Oh Pil-Gun | Improving performance of next-generation batteries

Received attention for suggesting a completely new doping method that enhances the performance of cathode materials for lithium-ion batteriesprofessor Oh Pil-GunA new doping method that can improve the performance of the cathode material of the next-generation secondary battery, lithium-ion battery, has been proposed and is attracting attention from the academic world. Pukyong National University announced that research on the new ion substitution method to enhance electrochemical reversibility of Co-rich layered materials for Li-ion Batteries, conducted jointly by professor Oh Pil-Gun and research professor Choi Jae-Hong from the department of nanotechnology engineering and professor Jo Jae-Pil from UNIST, was recently published in the internationally renowned journal (IF=29.698). In this study, the research team drew attention from the academia by presenting a doping method to secure the commercialization level and stability of ‘Co-rich layered’ material, which has higher energy density than cathode materials for conventional lithium-ion batteries. Doping is a process of adding a small amount of impurities to change the physical properties of a crystal. The research team doped sodium (Na) on the ‘cobalt-rich layered’ material and designed a material that shows high specific capacity and excellent stability under high operating conditions of 4.5 volts (V) or higher. Rather than finding conditions that allow the synthesis of existing simple doping through optimization, the research team has developed a new secondary doping method that helps sodium (Na) ions to be doped by partially substituting iron (Fe) ions for cobalt (Co) ions. Professor Oh Pil-Gun said, “I think that the new doping method we developed this time enables stable elemental substitution of new doping elements, so it can enable the performance of new materials such as nickel (Ni)-based materials and olivine materials as well as the performance of existing cathode materials,” he added, “If this can be applied to the current research on anode direct recycling, it is possible to develop a battery that is less than 80% cheaper and has more than 30% improved energy even with a commercial graphite anode.” As for the research, the research team carried out with the support of the national research foundation’s basic laboratory project selected in 2020 and the Korea institute of energy technology evaluation and planning's waste anode upcycling remanufacturing for circulation of low carbon resources project for low-carbon resource circulation that started in 2022.

Her Won-Bin & Oh Young-Sam| How do teenagers get cigarettes? The research results getting media attention

The ways teen-smokers get their cigarettes, ‘ttulgab, daelgu, angbari’Professor team of Her Won-Bin and Oh Young-Sam In a reality where it is illegal for teenagers to buy cigarettes, it was found that smoking teenagers purchase cigarettes through the processes of ‘ttulgab’, ’daelgu’ and ‘angbari’. This is the result of a research study by a team led by professor Her Won-Bin and Oh Young-Sam from the department of social welfare at Pukyong National University, in a paper titled ‘how do adolescent smokers evade cigarette sales restrictions: Focusing on how they purchase and acquire cigarettes’. This paper, published in the latest issue of , an academic journal published by the Korea institute for health and social affairs, volume 42, no. 3, research to review empirically examines the ways smoking adolescents obtain cigarettes, and examines the relationship between the method and situational factors. The research team at Pukyong National University conducted a case study using a single overall design method after in-depth interviews with 10 teen-smokers aged 14 to 18. As a result of their study, it was found that most teen-smokers get cigarettes by paying other people a certain fee and purchasing them on their behalf. It is an informal term commonly used by teen-smokers, the person who buys cigarettes instead of teenagers is called ‘angbari’, the brokerage fee with the store is called ‘ddulgap’, and the proxy purchase is called ‘daelgu’. In addition, high school students were able to purchase cigarettes more easily than middle school students when they went to a so-called ‘store breached in the cigarette trade to teenagers’ to purchase cigarettes or use a fake ID, and they also traded cigarettes through second-hand websites. When purchasing cigarettes by proxy purchase through adults or schoolmates in school, 'ddulgap' was usually 10% of the price of cigarettes, and middle school students paid relatively higher than high school students. Some girls said they had illegally dated adults to get cigarettes easily. Based on this, the research team proposed the mandatory installation of ID identification machines, the maximum limit system for cigarettes, and the ban on the sale, distribution, and advertisement of cigarettes online as practical alternatives to suppress the purchase and acquisition of cigarettes by adolescents. The research team said, “We expect that this study will contribute to the preparation of policies to constrain teen-smokers from purchasing cigarettes and will help to promote youth health by preventing and suppressing smoking among teenagers.” Meanwhile, the results of this study were reported in the on the 14th last month and received media attention.

Ko Min-Seong| New approaches to improve the performance of next-generation secondary batteries

Replacing the cathode of waste batteries as a catalyst to improve the performance of next-generation secondary batteriesProfessor Ko Min-SeongAs interest in the use of waste batteries is growing, interesting research results have been presented that the cathode materials of waste batteries can be recycled as catalysts for next-generation secondary batteries. A research team led by professor Ko Min-Seong from Pukyong National University (metallurgical engineering) announced that they have succeeded in improving the high-speed charging and discharging characteristics of vanadium redox-flow batteries, which are attracting attention as a next-generation large-capacity energy storage device because there is no fire risk, by using the cathode material of the waste lithium-ion battery. The electrode of a vanadium redox flow battery is where the reaction takes place and plays an important role in battery performance. Carbon material is mainly used for the electrode, but there is a problem in that the performance of the battery during charging and discharging is deteriorated due to the low reversibility (the property of changing to a certain state and returning to the original state). To solve this problem and improve the battery performance, a catalyst that usually increases the electrode reaction rate has to be applied, professor Ko Min-Seong's team used the cathode material of a spent lithium-ion battery as the catalyst. The research team paid attention to the fact that the electron structure of the cathode material of the waste lithium-ion battery was changed by repeated charging and discharging, and the number of oxygen vacancies increased. In the case of the electrode to which the catalyst was not applied in the evaluation of the full cell, the capacity decreased rapidly after 281 high-speed charging and discharging due to high resistance. On the other hand, in the case of a catalyst applied electrode, the characteristics of the cathode material of the spent lithium-ion battery greatly reduce the resistance when the redox reaction of the reactants occurs, enabling high-speed charging and discharging more than 1,000 times. Professor Ko Min-Seong's research team conducted joint research with Dr. Jang Hae-Seong from Lawrence Berkeley National Laboratory (LBNL) in the US, and reported to academia on a vanadium redox-flow battery with high reversibility and improved fast charging and discharging characteristics by applying the cathode material of a waste lithium-ion battery as a catalyst for a carbon electrode. He said, “This research is expected to contribute to the development of a vanadium redox-flow battery capable of high-speed charging and discharging, as well as a catalyst design using the cathode material of a waste lithium-ion battery. In the current situation where the amount of waste lithium-ion battery generation is expected to increase rapidly, recycling as a catalyst has been suggested as a novel alternative, so we can expect the effect of resource circulation.” His research was supported by the National research foundation of Korea, and was selected as a ‘hot paper' in 2022 in recognition of its excellence in research in (IF=12.732), an international academic journal in the field of materials and energy, and was also selected as the cover paper of the 36th issue published on September 28th.

“Calculate the appropriate quarantine period for the corona infected person based on the rapid antigen test result”Professor Kim Gwang-Soo While the discussion on the quarantine period for a person infected with COVID-19 continues, a study result from Pukyong National University that can calculate the quarantine period that can minimize the burden on the infected and the risk of infection is attracting academia attention. In Korea and other countries, people infected with COVID-19 are usually isolated for a certain period (5 to 10 days) after being confirmed, and individual may lose their infectivity before the quarantine period, or vice versa, remain infective. Therefore, criteria for determining an appropriate quarantine period have been required. Professor Kim Gwang-Soo (department of scientific computing) from Pukyong National University conducted a joint study with researchers Jeong Yong-Dam (ph.d. program in the department of mathematics), professor Jeong Yil-Hyo (department of mathematics) from Pusan national university, and researchers at Nagoya university in Japan and Indiana university in the US. The results of a study on the design of quarantine guidelines for COVID-19 infected people using the rapid antigen test results were presented. Professor Kim said, “It is possible to reduce the burden on the infected person while reducing the risk of infection if the quarantine termination conditions are well designed using the antigen test results to determine the quarantine period,” suggesting rather than isolating the infected for a fixed period, isolating them until the viral load falls below a threshold is suggested to reduce the burden on the infected. The joint research team conducted antigen testing under various conditions, such as testing interval and number of negative confirmations through computer simulation and calculated the risk of an infected person holding infectivity at the end of the quarantine and the duration of quarantine even after losing infectivity. According to the study, both risk and burden can be reduced by designing quarantine termination conditions based on the antigen test detection limit. If the threshold of antigen detection is higher than that of infectivity under the same level of risk control, multiple negative tests are required, conversely, if it is below the infectivity threshold, the quarantine period can be shortened by reducing the number of confirmations. Professor Kim Gwang-Soo of Pukyong National University recently published the paper ‘Designing isolation guidelines for COVID-19 patients with rapid antigen tests’ containing the results of this study as a co-first author in the international academic journal .

Moon Woo-Seok | What are the effects of the jet stream as the Arctic temperature rises?

“The arctic temperature rises may affect the jet stream pattern.”Professor Moon Woo-SeokRecently, as concerns about abnormal climates are growing around the world, a research result showing that the increase in temperature in the arctic affects the fluctuations of the jetstream is attracting academia attention. Professor Moon Woo-Seok’s team at Pukyong National University (Environmental atmospheric sciences) conducted joint research with professor John Wettlaufer from Yale university, USA, and published a paper ‘Wavier jet streams driven by zonally asymmetric surface thermal forcing' containing the research results recently and announced that it was published in (Proceedings of the national academy of sciences of the United states), a world-renowned academic journal. With the arctic warming four times faster than the global average, there has been growing interest in recent years about how the rapid rise in temperature in the arctic is related to the occurrence of abnormal climates. Until now, controversy has continued, with the hypothesis that the mid-latitude jet stream may be shaken due to an increase in the Arctic temperature, and opposing studies suggesting that the role of the Arctic in the change of the mid-latitude jet stream may be limited. However, both claims lacked theoretical or experimental evidence. In this study, prof. Moon's research team conducted computer experiments such as theoretical research and numerical simulations to present a theoretical basis for the first time in the academia. Through the study, the research team proved that the intensity of the jet stream weakens as the arctic temperature rises, and that when the intensity falls below a certain value, large-scale wave phenomena that connect to the upper atmosphere can occur rather than a reaction limited to the surface of the earth. The research team suggests that as the average velocity of the jet stream falls, the wave of the jet stream can become stronger as well. Prof. Moon said, “The study clarifies that temperature changes in the Arctic are an important factor that can increase extreme weather events not only in the region but also globally, especially in the mid-latitudes where we live,” and he added, “Especially, it is necessary to simultaneously study changes in the Arctic in order to find out the extent of climate change in Korea located in the middle of the mid-latitudes and the severity of meteorological disasters. I also think that the role of the Polar Research Institute, which visits the polar regions every year to study the climate conditions of the Arctic, should be further strengthened.”△ An image showing an increase in the arctic temperature and fluctuations in the jet stream.

Academia pays attention to research related to driving IoT sensors with discarded micromagnetic fieldsProfessor Hwang Gun-Tae A new technology that produces electric energy that can drive Internet of Things (IoT) sensors using a discarded micro-magnetic field is drawing attention from academia. Professor Hwang Gun-Tae (major of materials engineering) research team from Pukyong National University (President Jang Young-Soo) announced on September 1 that in collaboration with dr. Jang Jong-Moon's team at the Korea institute of materials science, professor Lee Sam-Nyeong's team from Korea maritime and ocean university, and professor Ryu Jeong-Ho's team from Yeungnam university, they have developed a 'magnetic field-driven hybrid energy harvesting device' with the highest output that can drive multi-functional IoT sensors. IoT, which has emerged as the core technology of the 4th industry, combines multi-function sensors and wireless communication functions, and can be utilized in society and industries, such as unmanned monitoring and early warning of national infrastructure. However, it is more important to ensure that electric energy can be smoothly supplied to the IoT sensor. It is inefficient to replace the batteries of many IoT sensors one by one, and it is difficult to periodically replace the batteries of IoT sensors installed in inaccessible places. In order to use the IoT sensor as an energy source, the magnetic field energy harvesting system, which collects micro-electric fields that are inevitably generated from power lines everywhere around us and converts them into energy, is a new and renewable energy technology that has been actively studied until recently. The previously developed magnetic field energy harvesting technology had a problem that real-time operation of multi-functional IoT sensors consuming tens of mW was impossible because the energy generation output was very low at the level of several milliwatts (mW). The hybrid magnetic field energy harvesting device developed by Professor Hwang Gun-Tae's team at Pukyong National University succeeded in outputting energy of up to 60 mW, which is about 10 times higher than that of the previous one. This research team succeeded in continuously driving a multifunctional IoT sensor that detects humidity, temperature, ultraviolet rays, light quantity, organic compounds, carbon dioxide, pressure, noise, and magnetic field in real time by applying this device. The research team discovered a new mechanical resonance mode while applying a hybrid method that simultaneously applies the piezoelectric effect and electromagnetic induction effect for the first time in the world. They introduced the new technology they discovered into a hybrid magnetic field energy harvesting device, and succeeded in dramatically increasing the energy generation output by controlling the oxygen vacancy concentration of Pb materials (Mg1/3Nb2/3) O3-Pb (Zr, Ti) O3(PMN-PZT) used to generate the piezo-electric effect.  The study was supported by the National research foundation and the Korea institute of materials science, and the results of this study were recently published as a cover paper in (IF: 19.9), a world-renowned academic journal in the field of materials engineering.△ A schematic diagram of a hybrid magnetic field energy harvesting system.△ Operation of multi-function IoT sensor using hybrid magnetic field energy harvesting (left) and item of multi-function IoT sensing (right)  △ An image of the paper cover.

Her Won-Bin and Oh Young-Sam | Published in an international academic journal on addiction

'Reliable' cigarette pack warnings reduce smoking among teenagers Professor Her Won-Bin and Oh Young-Sam A study found that the degree to which teenage smokers trust the warning images and text on cigarette packs have effects on the reduction in smoking rates. Professor Her Won-Bin and Oh Young-Sam from the department of social welfare at Pukyong National University, who are experts in addiction and social welfare, published a paper 'Examining the mediating effect of believability on the relationship between social influences and smoking behavior for smoking cessation among Korean youths' in the (IF: 11.555). The , where this paper is published, is a well-known academic journal that ranked first in the field of drug addiction (Journal impact factor/journal citation indicator) as of last year among SSCI-registered journals with international authority. According to the research results of the professor's team from Pukyong National University, teenagers who truly believe the warning images and texts on cigarette packs are more likely to quit smoking as their fearful feelings are transmitted to their cognition. The research team concluded this study result by analyzing the study sample data of 3,151 Korean youth smokers aged 13 to 18 in the 14th national youth risk behavior surveys (2018). The research team divided the factors influencing youth smoking into personal (family, friends, secondhand smoke, etc.) and social factors (cigarette advertisement, anti-smoking campaign, nonsmoking education), and found that 'believability' plays an important role in the process of these factors on smoking. As a result of the analysis, it was found that just looking at the warning labels on the cigarette packs caused a smoking reduction effect, and that it worked first on emotions such as fear and horror, and then on cognition (intention to quit smoking), and the key mediator in this process was 'reliability'. For the negative emotions from the warning images and texts on cigarette packs to act on the smoker's cognition, the smoker must accept it as 'reliable'. Professor Her Won-Bin said, "The study found that even when friends and family smokers influence adolescents, a stronger belief in the warning image or text of a cigarette pack is more likely to reduce the smoking factor." Professor Oh Young-Sam said, "This study is meaningful in that it conducted an empirical analysis of how the pictures and phrases of cigarette packs will be used in terms of social welfare and the relationship between addiction and social welfare."

Ko Min-Seong| Turning defects of secondary batteries into strengths

Contrarian research for 'securing additional capacity with explosive hazardous material in secondary batteries'Professor Ko Min-SeongContrarian research that can secure additional battery capacity by using a material known as the main cause of fire or explosion of secondary batteries is attracting attention. Pukyong National University announced that in case of overcharging exceeding the capacity of the graphite anode by leading the growth of defective carbon-nanotubes in the graphite anode, Prof. Ko Min-Seong (dept. of metallurgical engineering)'s team conducted research to effectively control the lithium formed on the graphite surface and utilize this as a battery capacity.  In addition to the disadvantage that the graphite anode material of the secondary battery has a low capacity, the formation of dendrite lithium on the graphite surface has been raised as a problem when overcharged or non-uniformly charged continuously. It is known that dendrite lithium causes deterioration of battery performance because of its low reversibility, and is known to be a major cause of deterioration of battery safety due to the risk of fire or explosion due to electric short circuit when continuously growing. Professor Ko Min-Seong's research team conducted joint research with Dr. Sung Jae-Kyung from the Massachusetts institute of technology (MIT) and Dr. Kim Nam-Hyung from Pacific Northwest National Laboratory (PNNL) to find a way to overcome the capacity limit of graphite anode materials with dendrite lithium, which threatens the stability of the battery. Their research turned flaws into strengths. The research team promoted the growth of carbon nanotubes with structural defects on the graphite surface by using a chemical vapor deposition process using a nickel catalyst and hydrocarbon gas. When this material was applied to the negative electrode, the research team confirmed that the lithium deposition was uniformly induced as the resistance of the electrode caused by the electrodeposition of lithium was alleviated. As a result of the experiment, it was found that the uniform lithium layer induced in this way showed high reversibility and operated with additional battery capacity. When driving a full cell in which the capacity of the positive electrode was designed to be larger than that of the negative electrode, the reversible capacity could be used even after 300 cycles. Professor Ko said, "I expect that defective carbon nanotubes can effectively control dendrite lithium to solve the battery stability problem, thereby reducing the unnecessary use of negative electrodes in electrode design, and at the same time improving battery energy density by using additional lithium." The research was supported by the Korea evaluation institute of industrial technology (KEIT) and National Research Foundation of Korea (NRF), and was recently published in (IF=12.732), an international academic journal in the field of materials and energy.

Oh Pil-Gun | Improving performance of next-generation batteries

Received attention for suggesting a completely new doping method that enhances the performance of cathode materials for lithium-ion batteriesprofessor Oh Pil-GunA new doping method that can improve the performance of the cathode material of the next-generation secondary battery, lithium-ion battery, has been proposed and is attracting attention from the academic world. Pukyong National University announced that research on the new ion substitution method to enhance electrochemical reversibility of Co-rich layered materials for Li-ion Batteries, conducted jointly by professor Oh Pil-Gun and research professor Choi Jae-Hong from the department of nanotechnology engineering and professor Jo Jae-Pil from UNIST, was recently published in the internationally renowned journal (IF=29.698). In this study, the research team drew attention from the academia by presenting a doping method to secure the commercialization level and stability of ‘Co-rich layered’ material, which has higher energy density than cathode materials for conventional lithium-ion batteries. Doping is a process of adding a small amount of impurities to change the physical properties of a crystal. The research team doped sodium (Na) on the ‘cobalt-rich layered’ material and designed a material that shows high specific capacity and excellent stability under high operating conditions of 4.5 volts (V) or higher. Rather than finding conditions that allow the synthesis of existing simple doping through optimization, the research team has developed a new secondary doping method that helps sodium (Na) ions to be doped by partially substituting iron (Fe) ions for cobalt (Co) ions. Professor Oh Pil-Gun said, “I think that the new doping method we developed this time enables stable elemental substitution of new doping elements, so it can enable the performance of new materials such as nickel (Ni)-based materials and olivine materials as well as the performance of existing cathode materials,” he added, “If this can be applied to the current research on anode direct recycling, it is possible to develop a battery that is less than 80% cheaper and has more than 30% improved energy even with a commercial graphite anode.” As for the research, the research team carried out with the support of the national research foundation’s basic laboratory project selected in 2020 and the Korea institute of energy technology evaluation and planning's waste anode upcycling remanufacturing for circulation of low carbon resources project for low-carbon resource circulation that started in 2022.

Her Won-Bin & Oh Young-Sam| How do teenagers get cigarettes? The research results getting media attention

The ways teen-smokers get their cigarettes, ‘ttulgab, daelgu, angbari’Professor team of Her Won-Bin and Oh Young-Sam In a reality where it is illegal for teenagers to buy cigarettes, it was found that smoking teenagers purchase cigarettes through the processes of ‘ttulgab’, ’daelgu’ and ‘angbari’. This is the result of a research study by a team led by professor Her Won-Bin and Oh Young-Sam from the department of social welfare at Pukyong National University, in a paper titled ‘how do adolescent smokers evade cigarette sales restrictions: Focusing on how they purchase and acquire cigarettes’. This paper, published in the latest issue of , an academic journal published by the Korea institute for health and social affairs, volume 42, no. 3, research to review empirically examines the ways smoking adolescents obtain cigarettes, and examines the relationship between the method and situational factors. The research team at Pukyong National University conducted a case study using a single overall design method after in-depth interviews with 10 teen-smokers aged 14 to 18. As a result of their study, it was found that most teen-smokers get cigarettes by paying other people a certain fee and purchasing them on their behalf. It is an informal term commonly used by teen-smokers, the person who buys cigarettes instead of teenagers is called ‘angbari’, the brokerage fee with the store is called ‘ddulgap’, and the proxy purchase is called ‘daelgu’. In addition, high school students were able to purchase cigarettes more easily than middle school students when they went to a so-called ‘store breached in the cigarette trade to teenagers’ to purchase cigarettes or use a fake ID, and they also traded cigarettes through second-hand websites. When purchasing cigarettes by proxy purchase through adults or schoolmates in school, 'ddulgap' was usually 10% of the price of cigarettes, and middle school students paid relatively higher than high school students. Some girls said they had illegally dated adults to get cigarettes easily. Based on this, the research team proposed the mandatory installation of ID identification machines, the maximum limit system for cigarettes, and the ban on the sale, distribution, and advertisement of cigarettes online as practical alternatives to suppress the purchase and acquisition of cigarettes by adolescents. The research team said, “We expect that this study will contribute to the preparation of policies to constrain teen-smokers from purchasing cigarettes and will help to promote youth health by preventing and suppressing smoking among teenagers.” Meanwhile, the results of this study were reported in the on the 14th last month and received media attention.

Ko Min-Seong| New approaches to improve the performance of next-generation secondary batteries

Replacing the cathode of waste batteries as a catalyst to improve the performance of next-generation secondary batteriesProfessor Ko Min-SeongAs interest in the use of waste batteries is growing, interesting research results have been presented that the cathode materials of waste batteries can be recycled as catalysts for next-generation secondary batteries. A research team led by professor Ko Min-Seong from Pukyong National University (metallurgical engineering) announced that they have succeeded in improving the high-speed charging and discharging characteristics of vanadium redox-flow batteries, which are attracting attention as a next-generation large-capacity energy storage device because there is no fire risk, by using the cathode material of the waste lithium-ion battery. The electrode of a vanadium redox flow battery is where the reaction takes place and plays an important role in battery performance. Carbon material is mainly used for the electrode, but there is a problem in that the performance of the battery during charging and discharging is deteriorated due to the low reversibility (the property of changing to a certain state and returning to the original state). To solve this problem and improve the battery performance, a catalyst that usually increases the electrode reaction rate has to be applied, professor Ko Min-Seong's team used the cathode material of a spent lithium-ion battery as the catalyst. The research team paid attention to the fact that the electron structure of the cathode material of the waste lithium-ion battery was changed by repeated charging and discharging, and the number of oxygen vacancies increased. In the case of the electrode to which the catalyst was not applied in the evaluation of the full cell, the capacity decreased rapidly after 281 high-speed charging and discharging due to high resistance. On the other hand, in the case of a catalyst applied electrode, the characteristics of the cathode material of the spent lithium-ion battery greatly reduce the resistance when the redox reaction of the reactants occurs, enabling high-speed charging and discharging more than 1,000 times. Professor Ko Min-Seong's research team conducted joint research with Dr. Jang Hae-Seong from Lawrence Berkeley National Laboratory (LBNL) in the US, and reported to academia on a vanadium redox-flow battery with high reversibility and improved fast charging and discharging characteristics by applying the cathode material of a waste lithium-ion battery as a catalyst for a carbon electrode. He said, “This research is expected to contribute to the development of a vanadium redox-flow battery capable of high-speed charging and discharging, as well as a catalyst design using the cathode material of a waste lithium-ion battery. In the current situation where the amount of waste lithium-ion battery generation is expected to increase rapidly, recycling as a catalyst has been suggested as a novel alternative, so we can expect the effect of resource circulation.” His research was supported by the National research foundation of Korea, and was selected as a ‘hot paper' in 2022 in recognition of its excellence in research in (IF=12.732), an international academic journal in the field of materials and energy, and was also selected as the cover paper of the 36th issue published on September 28th.

“Calculate the appropriate quarantine period for the corona infected person based on the rapid antigen test result”Professor Kim Gwang-Soo While the discussion on the quarantine period for a person infected with COVID-19 continues, a study result from Pukyong National University that can calculate the quarantine period that can minimize the burden on the infected and the risk of infection is attracting academia attention. In Korea and other countries, people infected with COVID-19 are usually isolated for a certain period (5 to 10 days) after being confirmed, and individual may lose their infectivity before the quarantine period, or vice versa, remain infective. Therefore, criteria for determining an appropriate quarantine period have been required. Professor Kim Gwang-Soo (department of scientific computing) from Pukyong National University conducted a joint study with researchers Jeong Yong-Dam (ph.d. program in the department of mathematics), professor Jeong Yil-Hyo (department of mathematics) from Pusan national university, and researchers at Nagoya university in Japan and Indiana university in the US. The results of a study on the design of quarantine guidelines for COVID-19 infected people using the rapid antigen test results were presented. Professor Kim said, “It is possible to reduce the burden on the infected person while reducing the risk of infection if the quarantine termination conditions are well designed using the antigen test results to determine the quarantine period,” suggesting rather than isolating the infected for a fixed period, isolating them until the viral load falls below a threshold is suggested to reduce the burden on the infected. The joint research team conducted antigen testing under various conditions, such as testing interval and number of negative confirmations through computer simulation and calculated the risk of an infected person holding infectivity at the end of the quarantine and the duration of quarantine even after losing infectivity. According to the study, both risk and burden can be reduced by designing quarantine termination conditions based on the antigen test detection limit. If the threshold of antigen detection is higher than that of infectivity under the same level of risk control, multiple negative tests are required, conversely, if it is below the infectivity threshold, the quarantine period can be shortened by reducing the number of confirmations. Professor Kim Gwang-Soo of Pukyong National University recently published the paper ‘Designing isolation guidelines for COVID-19 patients with rapid antigen tests’ containing the results of this study as a co-first author in the international academic journal .

Moon Woo-Seok | What are the effects of the jet stream as the Arctic temperature rises?

“The arctic temperature rises may affect the jet stream pattern.”Professor Moon Woo-SeokRecently, as concerns about abnormal climates are growing around the world, a research result showing that the increase in temperature in the arctic affects the fluctuations of the jetstream is attracting academia attention. Professor Moon Woo-Seok’s team at Pukyong National University (Environmental atmospheric sciences) conducted joint research with professor John Wettlaufer from Yale university, USA, and published a paper ‘Wavier jet streams driven by zonally asymmetric surface thermal forcing' containing the research results recently and announced that it was published in (Proceedings of the national academy of sciences of the United states), a world-renowned academic journal. With the arctic warming four times faster than the global average, there has been growing interest in recent years about how the rapid rise in temperature in the arctic is related to the occurrence of abnormal climates. Until now, controversy has continued, with the hypothesis that the mid-latitude jet stream may be shaken due to an increase in the Arctic temperature, and opposing studies suggesting that the role of the Arctic in the change of the mid-latitude jet stream may be limited. However, both claims lacked theoretical or experimental evidence. In this study, prof. Moon's research team conducted computer experiments such as theoretical research and numerical simulations to present a theoretical basis for the first time in the academia. Through the study, the research team proved that the intensity of the jet stream weakens as the arctic temperature rises, and that when the intensity falls below a certain value, large-scale wave phenomena that connect to the upper atmosphere can occur rather than a reaction limited to the surface of the earth. The research team suggests that as the average velocity of the jet stream falls, the wave of the jet stream can become stronger as well. Prof. Moon said, “The study clarifies that temperature changes in the Arctic are an important factor that can increase extreme weather events not only in the region but also globally, especially in the mid-latitudes where we live,” and he added, “Especially, it is necessary to simultaneously study changes in the Arctic in order to find out the extent of climate change in Korea located in the middle of the mid-latitudes and the severity of meteorological disasters. I also think that the role of the Polar Research Institute, which visits the polar regions every year to study the climate conditions of the Arctic, should be further strengthened.”△ An image showing an increase in the arctic temperature and fluctuations in the jet stream.

Hwang Gun-Tae | Development of a new technology that can produce electricity with a micro magnetic field

Academia pays attention to research related to driving IoT sensors with discarded micromagnetic fieldsProfessor Hwang Gun-Tae A new technology that produces electric energy that can drive Internet of Things (IoT) sensors using a discarded micro-magnetic field is drawing attention from academia. Professor Hwang Gun-Tae (major of materials engineering) research team from Pukyong National University (President Jang Young-Soo) announced on September 1 that in collaboration with dr. Jang Jong-Moon's team at the Korea institute of materials science, professor Lee Sam-Nyeong's team from Korea maritime and ocean university, and professor Ryu Jeong-Ho's team from Yeungnam university, they have developed a 'magnetic field-driven hybrid energy harvesting device' with the highest output that can drive multi-functional IoT sensors.

However, it is more important to ensure that electric energy can be smoothly supplied to the IoT sensor. It is inefficient to replace the batteries of many IoT sensors one by one, and it is difficult to periodically replace the batteries of IoT sensors installed in inaccessible places. In order to use the IoT sensor as an energy source, the magnetic field energy harvesting system, which collects micro-electric fields that are inevitably generated from power lines everywhere around us and converts them into energy, is a new and renewable energy technology that has been actively studied until recently. The previously developed magnetic field energy harvesting technology had a problem that real-time operation of multi-functional IoT sensors consuming tens of mW was impossible because the energy generation output was very low at the level of several milliwatts (mW). The hybrid magnetic field energy harvesting device developed by Professor Hwang Gun-Tae's team at Pukyong National University succeeded in outputting energy of up to 60 mW, which is about 10 times higher than that of the previous one. This research team succeeded in continuously driving a multifunctional IoT sensor that detects humidity, temperature, ultraviolet rays, light quantity, organic compounds, carbon dioxide, pressure, noise, and magnetic field in real time by applying this device. The research team discovered a new mechanical resonance mode while applying a hybrid method that simultaneously applies the piezoelectric effect and electromagnetic induction effect for the first time in the world. They introduced the new technology they discovered into a hybrid magnetic field energy harvesting device, and succeeded in dramatically increasing the energy generation output by controlling the oxygen vacancy concentration of Pb materials (Mg1/3Nb2/3) O3-Pb (Zr, Ti) O3(PMN-PZT) used to generate the piezo-electric effect.  The study was supported by the National research foundation and the Korea institute of materials science, and the results of this study were recently published as a cover paper in (IF: 19.9), a world-renowned academic journal in the field of materials engineering.△ A schematic diagram of a hybrid magnetic field energy harvesting system.△ Operation of multi-function IoT sensor using hybrid magnetic field energy harvesting (left) and item of multi-function IoT sensing (right)  △ An image of the paper cover.

'Reliable' cigarette pack warnings reduce smoking among teenagers Professor Her Won-Bin and Oh Young-Sam A study found that the degree to which teenage smokers trust the warning images and text on cigarette packs have effects on the reduction in smoking rates. Professor Her Won-Bin and Oh Young-Sam from the department of social welfare at Pukyong National University, who are experts in addiction and social welfare, published a paper 'Examining the mediating effect of believability on the relationship between social influences and smoking behavior for smoking cessation among Korean youths' in the (IF: 11.555). The , where this paper is published, is a well-known academic journal that ranked first in the field of drug addiction (Journal impact factor/journal citation indicator) as of last year among SSCI-registered journals with international authority. According to the research results of the professor's team from Pukyong National University, teenagers who truly believe the warning images and texts on cigarette packs are more likely to quit smoking as their fearful feelings are transmitted to their cognition. The research team concluded this study result by analyzing the study sample data of 3,151 Korean youth smokers aged 13 to 18 in the 14th national youth risk behavior surveys (2018). The research team divided the factors influencing youth smoking into personal (family, friends, secondhand smoke, etc.) and social factors (cigarette advertisement, anti-smoking campaign, nonsmoking education), and found that 'believability' plays an important role in the process of these factors on smoking. As a result of the analysis, it was found that just looking at the warning labels on the cigarette packs caused a smoking reduction effect, and that it worked first on emotions such as fear and horror, and then on cognition (intention to quit smoking), and the key mediator in this process was 'reliability'. For the negative emotions from the warning images and texts on cigarette packs to act on the smoker's cognition, the smoker must accept it as 'reliable'. Professor Her Won-Bin said, "The study found that even when friends and family smokers influence adolescents, a stronger belief in the warning image or text of a cigarette pack is more likely to reduce the smoking factor." Professor Oh Young-Sam said, "This study is meaningful in that it conducted an empirical analysis of how the pictures and phrases of cigarette packs will be used in terms of social welfare and the relationship between addiction and social welfare."

Ko Min-Seong| Turning defects of secondary batteries into strengths

Contrarian research for 'securing additional capacity with explosive hazardous material in secondary batteries'Professor Ko Min-SeongContrarian research that can secure additional battery capacity by using a material known as the main cause of fire or explosion of secondary batteries is attracting attention. Pukyong National University announced that in case of overcharging exceeding the capacity of the graphite anode by leading the growth of defective carbon-nanotubes in the graphite anode, Prof. Ko Min-Seong (dept. of metallurgical engineering)'s team conducted research to effectively control the lithium formed on the graphite surface and utilize this as a battery capacity.  In addition to the disadvantage that the graphite anode material of the secondary battery has a low capacity, the formation of dendrite lithium on the graphite surface has been raised as a problem when overcharged or non-uniformly charged continuously. It is known that dendrite lithium causes deterioration of battery performance because of its low reversibility, and is known to be a major cause of deterioration of battery safety due to the risk of fire or explosion due to electric short circuit when continuously growing. Professor Ko Min-Seong's research team conducted joint research with Dr. Sung Jae-Kyung from the Massachusetts institute of technology (MIT) and Dr. Kim Nam-Hyung from Pacific Northwest National Laboratory (PNNL) to find a way to overcome the capacity limit of graphite anode materials with dendrite lithium, which threatens the stability of the battery. Their research turned flaws into strengths. The research team promoted the growth of carbon nanotubes with structural defects on the graphite surface by using a chemical vapor deposition process using a nickel catalyst and hydrocarbon gas. When this material was applied to the negative electrode, the research team confirmed that the lithium deposition was uniformly induced as the resistance of the electrode caused by the electrodeposition of lithium was alleviated. As a result of the experiment, it was found that the uniform lithium layer induced in this way showed high reversibility and operated with additional battery capacity. When driving a full cell in which the capacity of the positive electrode was designed to be larger than that of the negative electrode, the reversible capacity could be used even after 300 cycles. Professor Ko said, "I expect that defective carbon nanotubes can effectively control dendrite lithium to solve the battery stability problem, thereby reducing the unnecessary use of negative electrodes in electrode design, and at the same time improving battery energy density by using additional lithium." The research was supported by the Korea evaluation institute of industrial technology (KEIT) and National Research Foundation of Korea (NRF), and was recently published in (IF=12.732), an international academic journal in the field of materials and energy.
