Adolescents who smoke and drink alcohol are more likely to use drugs- research results from the research team of professor Her Won-Bin and Oh Young-Sam at PKNU Reserch has shown that adolescents who have experienced smoking and alcohol are more likely to use drugs than those who have not. The team of professors Her Won-Bin and Oh Young-Sam in the department of social welfare at Pukyong National University, found out the correlation between adolescents' smoking, drinking, and drug use based on the gateway theory. The gateway theory is often used to explain the phenomenon where the use of safe or legally permitted drugs leads to the use of stronger (more addictive) drugs. It is in a similar context to the proverb, 'he that will steal an egg will steal an ox'. According to their study, the group with experience using narcotics had more experience with smoking and drinking at a statistically significant level than the group with no experience. Lifetime experience of using e-cigarette (incl. vape pen) was twice as high, lifetime experience of smoking was approximately 1.54 times higher, and lifetime experience of drinking alcohol was approximately 1.29 times higher. The results of the study showed that adolescents who had ever smoked e-cigarettes at least once in their lives were 2.42 times more likely to use narcotics than adolescents who had no experience at all. Additionally, the earlier (younger) one started smoking cigarettes during adolescence, the likelihood of using narcotics increased by 1.53 times each year, and the earlier one year of starting drinking, the likelihood of using narcotics increased by 1.58 times. The research team conducted the study using the results of the 17th (2021) online survey on adolescent health behavior conducted by the Korea disease control and prevention agency (KDCA) on 54,848 middle and high school students from 800 schools nationwide and analyzed the results of this study as supporting the gateway theory that the use of soft drugs such as smoking and drinking leads to the use of hard drugs such as narcotics. The paper 'Analyzing the relationship among adolescent alcohol, smoking, and drug use: utilizing the gateway theory’ containing this study was published in the latest issue (vol. 31, no. 2) of
PKNU research team presents a plan to improve electrolyte performance of all-solid-state batteries- research results of prof. Jung Sung-Chul's team published in the international journal of the Royal society of chemistry- the disorder of anions increases the stability of the solid electrolyte Pukyong National University (President Jang Young-Soo) announced that a research team led by professor Jung Sung-Chul (department of physics) proposed a method to improve the performance of Li6PS5Cl, a sulfide-based solid electrolyte used in solid-state batteries. In an ab initio calculation study conducted by professor Jung Sung-Chul with phd student Jeon Tae-Gon and master's researcher Cha Kyeong-Ho in the same department, he succeeded in quantitatively identifying the effect of the disordered arrangement of S and Cl anions in Li6PS5Cl, a solid electrolyte, on the physical properties of Li6PS5Cl. All-solid-state batteries are receiving a lot of attention because they can greatly increase the stability and energy density of the battery by replacing the flammable liquid electrolyte with a non-flammable solid electrolyte. Li6PS5Cl, based on the argyrodite structure, has excellent ionic conductivity, and its raw materials, Li2S, LiCl, and P2S5, are economical and easy to synthesize, so many studies are being pursued. In this study, professor Jung's team found that Li6PS5Cl is highly stabilized when disorder occurs compared to when there is no anion disorder, and the stabilized Li6PS5Cl shows high ionic conductivity (up to 4.6 mS cm 1). Additionally, the research team found that when anion disorder occurs, some of the Li ions move from around Cl to close to S, and that this rearrangement of Li contributes decisively to improving the stability and increasing conductivity of Li6PS5Cl. Professor Jung Sung-Chul said, "I believe that this study suggests that precisely controlling the ionic disorder of the solid electrolyte is another way to improve the electrochemical performance of not only Li6PS5Cl but also other solid electrolytes." The study was conducted through support from the mid-career researcher program supported by the Ministry of science and ICT and the LAMP project hosted by the Ministry of education, and recently published in
PKNU developed 'dual nanopatterning process' for the first time- joint research with Busan national univ., Korea university, POSTECH, and KICET△ Researchers at Pukyong National University. From the left, professor Park Woon-Ik, Dr. Park Tae-Wan, master candidate Kang Young-Lim, and Kang Eun-Bin in integrated bachelor and master's program. Pukyong National University announced that professor Park Woon-Ik's (materials science and engineering major) research team was the first to develop an advanced concept and technology of dual nanopatterning process that forms a 20-nano ultra-fine pattern on an 8-inch wafer in the semiconductor process. With the development of next-generation electronic devices, the development of nanopatterning processes to implement highly integrated semiconductor circuits is essential to produce various electronic devices. Photolithography is mainly used as the current representative nanopatterning process, but researchers have been developing new processes to replace it due to limitations in pattern resolution, expensive equipment, and complicated process steps. 'Nanotransfer printing', which exhibits high pattern resolution at a low cost, is considered one of the new alternative processes, but this has also been pointed out as a disadvantage in that the pattern resolution is largely dependent on the pattern size of the master mold. To solve this problem, the research team applied a method that combined the self-assembly phenomenon of block copolymers containing silicon (Si) with the nanotransfer printing process and finally they succeeded in developing a dual nanopatterning process to form regularly aligned 20-nanometer silica (SiOx) structures on an 8-inch wafer. Professor Park Woon-Ik said, "I expect that the dual nanopatterning process will greatly contribute to the development of next-generation semiconductor technology in the future because it can implement highly integrated patterns with more complex circuits at a cost that is one-tenth of that of existing patterning technologies." This research was conducted through the basic research laboratory (BRL) and mid-career researcher program provided by the National research foundation of Korea (NRF) under the Ministry of science and ICT (MSIT), and the paper containing the research results, 'direct printing of ultrathin block copolymer film with nano-in-micro pattern structures' was published in the international academic journal
Joint research team of prof.

The joint research team, which included researchers from Pukyong National University, Busan national university, Sungkyunkwan university, and Mississippi state college, identified the growth mechanism of colorless copper, the cause of oxidation resistance, and the specificity of the grown copper surface through theory and experiment. The paper 'self-oxidation resistance of the curved surface of achromatic copper' containing the results of this research was introduced in the world-renowned academic journal
Teen-smokers should try to quit smoking at least once, even if they fail- research result from prof. Her Won-Bin, and prof. Oh Young-Sam's team at PKNU draws attention from the academia△ Prof. Her Won-Bin, prof. Oh Young-Sam and prof. Jeong Hye-JinAmong the teen-smokers, those who try to quit smoking at least once had a significantly lower levels of addiction to nicotine than the group who do not try. This is the result of a study conducted by a joint research team led by professors Her Won-Bin and Oh Young-Sam from the department of social welfare at Pukyong National University and professor Jeong Hye-Jin from the department of public administration at Busan National University through a survey of 349 teen-smokers under the age of 18 who had smoking experience. The research team utilized an empirical study targeting Korean teenagers based on the research results (2019) of the health and tobacco control division of California, USA that smokers who did not try to quit smoking before the age of 26 are likely to remain smokers for life. As a result of collecting sample data in the form of a questionnaire survey, the average age of the respondents was about 16 years old, and the average duration of smoking was 2.6 years. The research team analyzed them by dividing them into a group that had tried to quit smoking and a group that had not tried. As a result of their study, 69% of the non-trial group who had never tried to quit smoking were male adolescents, which was significantly higher than the attempt group. Teens who did not go to school were more likely to be in the group who had tried to quit smoking at least once. The research team speculated that the reason for the large number of out-of-school youth in the trial group was economic factors or the effect of the youth center's anti-smoking program. The research team suggested, "Research results show that nicotine addiction increases if you do not try to quit smoking even once," and added, "For teenagers to be successful in quitting smoking in the long term, even if they fail, they should try to quit smoking as soon as possible, practice quitting and build up the stamina to quit." They said, "We expect that the results of this study will help design and develop smoking cessation programs that consider smoking-related factors and characteristics of each group." The paper 「Examining Predictors of Nicotine Dependence in Korean Adolescents: comparing ever quitters and never quitters」 containing the results of this study was introduced in an international journal,
Korean researchers have solved the problem of 'preservation of the parathyroid glands', the biggest challenge in thyroid surgery- a joint research by PKNU, Kosin Univ. & UNIST... obtained MFDS approval and a US, China patent△ professor Ahn Ye-Chan.Researchers in Korea have succeeded in resolving one of the biggest challenges in thyroid surgery, the preservation of the parathyroid glands. Pukyong National University (President Jang Young-Soo) announced that a research team led by professor Ahn Ye-Chan from the department of biomedical engineering developed a technology to preserve the parathyroid gland during thyroid surgery and completed FMDS approval as well as international patent registration. Thyroid cancer, which is the most common cancer in Korea, has a high survival rate, but patients who have undergone thyroid surgery often experience symptoms such as numbness in the hands and feet, abnormal sensations around the mouth, chest tightness, or body convulsions in the hands or face. These symptoms are the most common and serious complication of thyroid surgery and are caused by hypofunction of the parathyroid gland. Since the size of the parathyroid gland is very small, it is difficult to distinguish it with the naked eye from the surrounding adipose tissue and even if the parathyroid gland is found, preserving blood flow to this tiny organ is not easy even for experienced surgeons, so it has been considered the biggest challenge in thyroid surgery. To solve this problem, professor Ahn Ye-Chan at Pukyong National University developed a 'technology to detect invisible parathyroid glands using near-infrared autofluorescence imaging to preserve parathyroid glands during thyroid surgery' in collaboration with professor Lee Kang-Dae from the department of otorhinolaryngology at Kosin University Gospel Hospital and professor Bae Seong-Cheol from the Department of Biomedical Engineering and Kim Yi-Geun at the Ulsan National Institute of Science and Technology (UNIST). Based on high sensitivity and low noise performance, near-infrared imaging equipment using this technology detects very weak parathyroid autofluorescence signals without turning off the lights. Since the surgeon can check the position of the parathyroid gland in real time during surgery, the organ can be preserved accordingly. From February to the 4th of this month, the research team obtained approval from the Ministry of Food and Drug Safety for the manufacture and sale of near-infrared imaging equipment using this technology while registering four patents on this source technology in succession in the US and one in China. Professor Ahn Ye-Chan at Pukyong National University, explained that, "by registering this technology as a patent in the US and China for solving one of the biggest challenges in thyroid surgery, we secured an opportunity to enter the global market. I expect that it will attract a lot of attention especially in the Chinese market where the number of thyroid surgeries is rapidly increasing."
대외협력과 (2023-09-01)COUNT 134New technology development in 'photovoltaic & LED display in one'- joint research between PKNU and Korea institute of energy research published research paper in international academic journals and completed patent registrationA 'high-efficiency solar LED display module' has been developed that can utilize solar power generation during the day and LED display at night with a single module. Pukyong National University (President Jang Young-Soo) announced that a research team led by professor Shin Dong-Yoon (dept. of nanotechnology eng.) and the research team of senior researcher Kang Ki-Hwan from the photovoltaic research center at Korea institute of energy research developed a new solar display convergence technology through joint research. The joint research team succeeded in converging a solar module and an LED display module, while dramatically lowering the reduction in electricity production efficiency of the solar module by 3%. Unlike existing solar modules that only produce electricity, it is expected to be able to utilize not only electricity generation but also media playback functions when this developed module is installed on the outer wall of a building. Existing LED display modules excessively block sunlight reaching the solar module, reducing the solar module's electricity production efficiency by 23%, so there was a limit to the fusion of these two modules. In addition, since the lifetime of the LED display is shorter than that of the solar module, there has been a problem that even the solar module must be replaced when it malfunctions. The research team solved these problems by applying a lattice structure. By installing LEDs at the intersections of grids, solar light reaches the empty areas of the grids without interfering with the solar modules, developing detachable solar LED display modules. Especially when a lattice-type structure is applied, another problem arises in that electricity production efficiency decreases due to a lattice shadow when sunlight is incident on the module at an angle according to the altitude of the sun. In response, the research team solved this problem by installing a reflector on the wall of the lattice structure to reflect sunlight back to the solar module. As a result of the simulation after the research team installed this module in a building in Seoul, it was shown that the LED display module could be operated for up to 22 hours at night with the electricity produced during the day. Following the publication of the paper 'grid-type LED media facade with reflective walls for building-integrated photovoltaics with virtually no shading loss', which contains the results of this research, in the international journal

Identifying the paradoxical 'quantum scar mode' that keeps stable even in unstable quantum chaos- joint research result of PKNU, Hanyang university, and the IBS A joint research team from Pukyong National University, Hanyang university, and the Institute for basic science (IBS) succeeded in identifying the paradoxical 'quantum scar mode', which states that a stable state exists in photonic crystal quantum chaos for the first time. The joint research team of professor Park Hee-Chul (Physics) from Pukyong National University, professor Park Moon-Jip (physics) from Hanyang university, and doctor Lee Chang-Hwan from the physics of complex systems group in IBS, recently published a thesis titled ‘Bloch theorem dictated wave chaos in microcavity crystals’ in an international journal in the field of optics. It is common knowledge in physics that an object with high potential energy falls to a more stable position, but it can be distinguished by two states: a stable fixed point where the object balances forces and does not move, and an unstable fixed point where force balance is broken even if it is slightly out of position. On the other hand, this common sense can be defied in quantum mechanics. It has been suggested that particles can be stably located even at unstable fixed points due to interference caused by the duality of particles and waves. Such an interesting quantum state is called the 'quantum scar mode'. If a stable quantum scar mode can be implemented in a complex quantum chaotic structure even with external interference, it can be widely used in quantum technology such as quantum sensing. For this reason, attempts to implement a quantum scar state by confining photons to an unstable fixed point inside a micro-resonator are continuing in the physics world. Pukyong National University and the research team theoretically identified the existence of a quantum scar mode in a photonic crystal in which several resonators are arranged in a lattice structure. Focusing on the fact that the movement of light can be effectively controlled using photonic crystals in which multiple resonators interact, the research team proposed a new platform that can control the dynamic localization of chaotic states in an array of resonators by combining chaos and periodicity. Although the quantum scar mode has been proposed in a single resonator in the academia, this is the first time that it has been proposed in a photonic crystal structure in which multiple resonators are connected. Professor Park Hee-Chul said, "The fusion of quantum chaos and spatial regularity, which is the core of this research, is a method to effectively control quantum chaos. Through this, I see that it can be a window to look into and control quantum in the classical world, and I expect that it will be a new quantum platform that is widely used in quantum technology."
Developed carbon dots for UV-light sensing that measures UV rays with ‘a single film’- Professor Yang Hyun-Kyung A film-type UV sensor that can detect both the UV index and the cumulative amount of UV exposure has been developed and is attracting attention from the academic world. It is 'carbon quantum dots for UV-light sensing' recently developed by professor Yang Hyun-Kyung (dept. of electrical, electronics and software engineering, the BrainKorea 21 Four) and research professor Park Jin-Young (dept. of electrical, electronics and software engineering) from Pukyong National University. Ultraviolet rays are an essential element for producing vitamin D in the human body while exposed to the skin, but excessive exposure causes skin aging, melanoma, or burns, so ultraviolet rays are used in various fields such as medical and sports. Existing UV meters on the market require sophisticated systems such as amplifiers and are expensive and have low portability due to complicated assembly processes. There is a problem in that the cumulative amount of UV exposure cannot be intuitively checked. The team of professor Yang produced a film that detects ultraviolet rays using carbon quantum dots, a nano material made of carbon particles. As a result of the experiment, this film showed the effect of changing color differently according to the cumulative amount of UV exposure, and the speed of film color change according to the intensity of the exposed UV light. Using this 'UV sensor using carbon quantum dots', it is very attractive that the UV index and cumulative UV exposure can be intuitively monitored. It is also a great advantage of this sensor that it can be manufactured at low cost because it does not require the construction of an amplifier or system. Professor Yang said, "This sensor is highly portable in that it can be manufactured in various forms as well as film form, and is also very inexpensive, so I expect that it will be widely applied in real life." Professor Yang applied for a patent (domestic/PCT/USA) for this research result, and the paper 'photobleach effect of multi-color emitting carbon dots for UV-light sensing' containing the research result was recently published in the international journal

대외협력과 (2023-05-30)COUNT 181Prof. Oh Pil-Gun proposes research results on securing stability of lithium secondary batteries- his paper published on , an international journal of materials Pukyong National University announced that professor Oh Pil-Gun’s (dept. of nanotechnology engineering) research team recently published a study on the coating method for securing the stability of lithium secondary batteries in (Wiley, IF 15.153), a world-renowned academic journal of materials. In this study conducted by professor Oh Pil-Gun at Pukyong National University with phd student Embleton Tom James (UK), he presented the results of a coating study for stabilization of the surface of Ni (nickel)-based layered anode material, and the results of the research were recognized by the academic community. As the market for large-sized lithium secondary batteries has recently expanded, research to secure deterioration stability of lithium secondary battery cathode materials according to high-capacity characteristics, aiming at high energy and high stability, is a major concern. Ni (nickel)-based layered cathode materials are mostly used in lithium secondary batteries currently, this cathode material reacts with carbon dioxide and moisture in the atmosphere to deteriorate the surface structure and form residual lithium, which causes problems that decrease the capacity and lifespan of the secondary battery. Professor Oh Pil-Gun's research team applied a coating process to the surface of the anode material to prevent direct contact between the material and the electrolytes, thereby imparting electrochemical and physical stability. As a result of the study, it was found that the cathode material subjected to the coating process not only withstands exposure to high-temperature and high-humidity environments, but also minimizes material deterioration during the storage and transportation of high-nickel cathode materials and the manufacturing process of secondary batteries at industrial sites. Professor Oh Pil-Gun said, “This study is meaningful as a study that maximizes the performance of previously commercially available cathode materials. In this field, I believe that investment from the government and companies is also needed for research on converting current secondary particle-type materials into single particles and direct recycling research that heat-treats and reuses waste anode materials.” As for this research, it is carried out with the support of the National research foundation of Korea's basic research lab project, which was selected in 2020 by professor Oh Pil-Gun's research team, and the project, ‘development of waste anode upcycling remanufacturing innovation technology for low-carbon circulation’ managed by the Korea institute of energy technology evaluation and planning, which started in 2022.

The cover of this journal, dated February 15th, was covered by the research team of professor Lee Bo-Ram’s review article, ‘Passivation strategies for mitigating defect challenges in halide perovskite light-emitting diodes’. The research team is made up with great scholars such as professor Lee Bo-Ram and dr. Xinyu Shen from Pukyong National University, professor Kang Kee-Hoon from Seoul National University, professors Richard H. Friend and Samuele D. Stranks from university of Cambridge in England, and professor Henry J. Snaith from university of Oxford. In this paper, the research team presents problems and solutions to be overcome in current research on perovskite LEDs, and promotes research on the development of perovskite LEDs that maintain high efficiency and high stability. Especially, various previously reported defect passivation strategies are systematically reviewed, summarized, and presented through four basic principles (ionic bonding, coordinate covalent bonding, hydrogen bonding, and core-shell structure) and their synergistic multiple combinations. Metal halide perovskite (MHP) is a material with great potential for next-generation display applications due to its high color purity and high photoluminescence quantum yield. Perovskite materials are known to have higher defect tolerance than conventional semiconductor materials, but in fact, various defects occur in the process of thinning perovskite materials. In addition, defects occur on multilayer between the electron transport layer and the perovskite material, which limits the device performance of LEDs. To prevent device performance degradation, many researchers have continuously improved the performance of perovskite LEDs through various defect passivation strategies, and currently, external quantum efficiencies of up to 28.9%, which are close to commercialization, have been reported. Professor Lee Bo-Ram said, “We expect that the results of this paper will serve as a reference for industry and academia to discover the greater potential of perovskite for photoelectronic devices.” As for the research, it was carried out with support from the Ministry of science and ICT (MSIT) and the National research foundation's BrainLink project, nano and material technology development program, young researcher program, mid-career researcher program, and the key research institutes for universities support project.△ The research team.

대외협력과 (2023-03-23)COUNT 277A research team led by Prof. Jung Sung-Chul at PKNU identified the mechanism of ion diffusion in solid-state batteries- ion conduction at a commercially available level confirmed... published in the international journal of the Royal society of chemistry According to Pukyong National University, professor Jung Sung-Chul (dept. of physics) and his research team succeeded in identifying the mechanism of ion diffusion in solid electrolytes, a key element of solid-state batteries. Lithium-ion batteries currently used in portable electronic devices and electric vehicles use a flammable liquid electrolyte, which may cause ignition or explosion. Solid-state batteries are attracting attention as next-generation batteries because they use non-flammable solid electrolytes instead of liquid electrolytes to significantly improve the safety and energy density of batteries, however, the ion conductivity of the solid electrolyte is still not up to the level of the liquid electrolyte (more than 1 mS/cm), making it difficult to commercialize the product. Professor Jung and a combined master’s and doctoral student Jeon Tae-Gon identified the lithium-ion diffusion process of 'Li3Y(Br3Cl3)', a halide solid electrolytes that has recently attracted attention due to its high stability against oxidation and high ionic conductivity, at the atomic level through first-principles molecular dynamics simulation. The research team of professor Jung suggested that the ionic conductivity of the most thermodynamically stable Li3Y (Br3Cl3) structure can reach up to 22.3 mS/cm. It was also confirmed that at this conductivity, the diffusion of lithium ions proceeds through concerted diffusion, in which two ions move simultaneously, rather than a single ion. Professor Jung said, “The concerted diffusion mechanism is completely different from vacancy diffusion, which is known as the diffusion method of lithium in many solid electrolyte materials so far, suggesting that we should also consider concerted diffusion as one of the diffusion mechanisms of lithium in future studies.” The research team also confirmed that the conductivity of Li3Y (Br3Cl3) is 1.4 to 7.4 times higher than that of other halide solid electrolytes, Li3YCl6 and Li3YBr6, accordingly, they suggested that a halide solid electrolyte with more improved ionic conductivity could be developed through appropriate mixing of halide anions. The research, conducted by professor Jung’s research team with support from the Ministry of science and ICT (mid-level research), was published online on February 1st in an authoritative international journal
