What will the snacks our professor developed taste like?

'Hot Topic', Dried pollack snacks developed by a university professorProf. Cho Sueng-mok of PKNU transferred technology to SMEs ... Launched snack with 54% pollack content△ The research team of Prof. Cho Sueng-mok (3rd from the left)'s commemorative photo ⓒPhoto Lee Sung-jae (PR Team)How about making snacks from pollack, a 'national fish' that has a variety of ways to eat it as numbers of names it has, such as frozen pollack (Dong-tae), fresh pollack (Saeng-tae), dried Pollack (Hwang-tae).It is a hot topic that the technology for manufacturing pollack snacks developed by a university professor has been released as an actual product after SMEs received the technology transfer.This is the 'Badasori Fish Pop' released by Sunhae F&S (CEO Sim Ui-heon, Gwangju, Gyeonggi-do), a small and medium-sized business in the marine product sector.This snack was developed by the research team of Professor Cho Sueng-mok's (Dept. of Food Science and Technology) at Pukyong National University as part of the research project of the Ministry of Oceans and Fisheries (development and commercialization of processed traditional fishery foods considering the characteristics of each sea). Since the snack was released in earnest in February, reviews have been continued on social media and are getting word of mouth.Launched in three types of tastes, seaweed, cheese, and consomm?, this product is attracting attention as a nutritious snack with high nutrition and flavory taste.This snack attracts attention because it is a high-protein product with fully 54% of pollack, the raw material. In the case of a shrimp snack currently on sale, considering that the shrimp content is 8.5%, this is a very high proportion.Even though it has a high content of pollack, it does not have a strong fish taste, and the texture is the same as that of a well-known crunchy snack that does not feel like a grilled fish jerky or dry fish.Professor Cho said, "Unlike other snacks, we applied a technology that uses rice flour, not flour or starch, to create a two-layer structure to create a crunchy texture."Professor Cho is an expert in the field of aquatic processing and food chemistry, and is conducting research on customized health functional foods, research on the development and commercialization of processed aquatic foods, and research into functional materials of useful ingredients derived from seafood.He said, "So far, marine products have a low proportion in the snack market compared to agricultural products. Following this study, which suggested the possibility of developing applied premium products using fish, we plan to continue research on the use of various marine products."

PKNU student, "The medical laboratory equipment is too expensive, so I just made it."

PKNU student, "The medical laboratory equipment is too expensive, so I just made it." 'Antibody Dispenser' developed by Han Won at Dept. of Biomedical Engineering, the thesis published in international journals An undergraduate student at our university has been drawing public attention for developing an 'antibody dispenser', a medical laboratory equipment that costs hundreds to tens of millions Korean won. Pukyong National University (President Jang Young-Soo) announced on March 25 that Han Won (age 25), a fourth grader in the Department of Biomedical Engineering, developed a compact 'Antibody Dispenser' using a 3D printer. Antibody dispensers are essential equipment for manufacturing test kits that diagnose liquid samples such as corona test kits and pregnancy diagnosis apparatus. When the antibody dispenser sprays two or more antibodies in parallel with a even thickness on the test kit paper, the diagnoser cuts the paper to the required length for the test and uses it to diagnose antigens such as corona. The previously developed antibody dispenser was difficult to equip in a small laboratory due to its high price and large volume. In addition, since the test kit paper of a certain length is fixed, there is a limit to the length that can be printed at one time by moving the head spraying the antibody. The antibody dispenser developed by Mr. Han uses a method of moving the test kit paper with a fixed head that sprays the antibody, contrary to the previous one. In this way, the antibody can be sprayed in parallel at a certain thickness while being small, and the thickness of the antibody line can be adjusted. This is a similar actuation principle to office printers. This antibody dispenser can print constantly without limiting the length of the test kit paper if only paper and antibody are supplied repeatedly. In addition, it was developed with Arduino and 3D printer, which are public based developed hardware, so it is possible for researchers to make equipment themselves. An advisory professor Shin Joong-ho (Dept. of Biomedical Eng.) of Pukyong National University said, "The manufacturing cost of the antibody dispenser developed by Han this time is only 30,000 to 40,000 Korean won. I expect this antibody dispenser to be helpful in facilitating various experiments and research to quickly and inexpensively test antigens, like recent coronavirus-related research." Han Won's paper, 'Low-cost, open-source 3D printed antibody dispenser for development and small-scale production of lateral flow assay strips', research on the development of this antibody dispenser, was recently published in the international journal .

Give us a sec, professor | Prof. Jeong Geun-joo

The reason journalists keep visiting Prof. Jeong Geun-joo these days The media’s attention to the first case of the judgment role of ’harm caused by light reflection from skyscraper’ △ Professor Geun-joo Jeong is talking about light reflex research in the lab. ⓒPhoto Lee Sung-jae (PR Team) Recently, the university’s public relations team received a phone call from many reporters from the press asking for an interview with Professor Jeong Geun-joo (age 60, Dept. of Architectural Engineering) at Pukyong National University. What is the story here? That is because Professor Jeong’s research results played a decisive role in the Supreme Court’s judgment on ’harm caused by light reflection from skyscrapers’ that came out on March 11th. On that day, the Supreme Court affirmed the trial court that won lawsuit of some plaintiffs in the appellate court for compensation, in which residents U-dong, Haeundae-gu, Busan, filed a lawsuit against ’HDC Hyundai Industrial Development’, a construction company of Hyundai I-Park. The Supreme Court’s judgment is drawing public attention as it was the first to admit light reflex from skyscrapers causes harm. It was the conclusion after 12 years of the lawsuit. What happened in the meantime? Lawsuits by residents complaining of harm from light reflections from skyscrapers first began in 2009. Residents lost in the first trial. There was no evidence to admit that the residents were suffering. So, in August 2011, the second trial (Busan High Court) court commissioned the Architectural environment laboratory of Pukyong National University, where Professor Jeong is the lead researcher. They asked for research and investigation on the damage condition of residents. After two months of research by Professor Jeong’s research team, it was an investigation report titled 「Disability glare and life disturbance problems at the Gyeongnam Marina Apartment caused by Haeundae I-Park’s Specular reflection」. This investigation report marked the decisive beginning of the lawsuit. Based on this report, in June 2013, the Busan High Court admitted that residents are suffering the harm of ’disability glare’, making them difficult to identify objects due to excessively shining light. It was also decided that a total of about 200 million won was paid to some victims, ranging from 1.32 million won to 6.68 million won per person. However, due to the construction company’s objection to the second trial, the lawsuit went to the Supreme Court, and five years later, on the 11th, the Supreme Court confirmed judgment, "There is a disturbance in life that exceeds the limit of tolerance due to the sunlight reflected on the glass on the outer wall of the building." The residents finally won. Professor Jeong introduced the research results, "As a result of our research team’s on-site investigation and simulation, it was found that Haeundae I-Park (the defendant) reflected sunlight in a specular surface (mirror), causing a disability glare to exceed the limit in the Gyeongnam Marina Apartment (the plaintiff)." He continued, "The luminance of light exceeded 300,000 cd/m2 in the field survey, and the maximum was around 70,000,000 cd/m2 in computer simulation. This far exceeds the limit of 25,000 cd/m2." Professor Jeong said, "Buildings are getting higher and higher, and glass materials are inevitably used. This is because the higher the building, the lighter the building load. In addition, the attractive exterior and good see-through in the room is another reason to prefer glass." He stressed, "Therefore, it is necessary to review it in advance at the architectural design stage to prevent light reflection problems. It should be designed in consideration of whether it causes damage to nearby residents."   Professor Jeong, who provided clues to this unexampled judgment, is considered as an architectural engineer who is endowed with both practice and theory. His majors are in the fields of architectural engineering and architectural environment. Prior to his appointment as a professor at Pukyong National University in 2007, he stands unrivaled the genre of architectural environment based on his know-how accumulated in industrial sites such as Kunwon Engineering and Samsung Heavy Industries. He mainly teaches and studies the field of ▷’light environment’ dealing with indoor illumination and outdoor light pollution, including ▷’thermal environment’ such as heating and cooling for energy conservation, and ▷’acoustical environment’ dealing with noise problems and sound facilities. The mainstream in the field of ’architectural engineering’ has been recognized as the field of construction management and structure at the construction site so far. However, as shown in the case of the Supreme Court’s judgment, the importance of the architectural environment field has emerged and is attracting attention as a study with great growth potential. Professor Jeong has published 69 research papers (11 SCI papers) on the field of architectural environment and equipment. For his contributions to the development of the architectural culture, he received a citation from the Minister of Land, Infrastructure and Transport (MOLIT), and a thesis award from the Korean Institute of Architectural Sustainable Environment and Building Systems (KIAEBS). Having studied both his bachelor’s and master’s and doctoral degrees at Pukyong National University, he served as vice provost of Engineering College,  the vice director of Planning and Administration, and director of Planning and Administration, he devoted himself for the university development. He said, "The architectural environment is an important study that needs to be developed to solve humanity’s homework of environmental protection and energy conservation," he added, "I will do my best to help my students properly explore the field of architectural environment and develop their own dreams."

Pukyong National University (President Jang Young-Soo) announced that Jo Gwang-je (age 50), Owner of PukyongSa (Daeyeon-dong, Busan), which is a printing and copying service shop, donated 20 million won for the development of the university. On the morning of that day, Mr. Jo visited the president's office on the 3rd floor of the campus headquarters at Pukyong National University and said, "Our main customers, Pukyong National University professors, students, staff, used our service a lot, so we were able to settle down here in the campus street. I want to convey my appreciation even a little." Mr. Jo has been running a copy place near the side gate of Pukyong National University's Daeyeon Campus since 2015, which produces booklets for schools, companies, and government offices, or provides services such as printing and copying thesis for students. There were many difficulties at the beginning of the business, but the business stabilized with some buzz marketing among members of Pukyong National University, as a result, the number of users increased. Now I want to repay them. One of the important motives of this donation is his special affection for his alma mater, who is also an alumnus of Pukyong National University (class of '91, Dept. of Chemistry). He said, "Pukyong National University is a place where I spent all my twenties, both undergraduate and master's courses. I would be very happy if my donation is small but contributes to the development of my alma mater." Mr. Jo said, "The advice of Professor Kim Young-il, who was my supervisor when I was struggling with the IMF ahead of college graduation, helped me a lot, and now I am receiving a lot of help from professors at Pukyong National University, who are juniors and clients. Now, I want to give a little help to Pukyong National University and the students." Pukyong National University responded that the donation by Mr. Jo was more meaningful in that it was made in difficult conditions such as a decrease in sales due to Corona 19. "Although it is a difficult time, we are continuing our efforts to expand our customers. I believe that if everyone plucks up courage little by little and finds a way to support each other, we will be able to overcome this time wisely," Mr. Jo said. △ People who attended the development fund delivery ceremony are taking commemorative photos for the group.

We had a telephone interview with him on March 17th, who has been living in Seoul ever since graduating from Pukyong National University. The voice over the phone was as raspy and thick as when he was singing. Sometimes his accent had a Busan dialect. "The moment I saw the word 'Pukyong National University' in the text, I was so glad and delighted." That was what he said after seeing the message sent to him by the reporters of Pukyong Today, and we felt a strong sense of identity. How can we describe his campus life at Pukyong National University in the past? He was a youth who lived more addicted to music than his original major, design. In his campus life, he played the keyboard and sang in the band 'Auraji'. It is said that he enjoyed singing and playing in front of his juniors during lectures, hiding the keyboard at his place, under the computer in the laboratory of the Department of Industrial Design. I come up with his wonderful keyboard playing scene that I saw on the air. How did Kim come to have his own unique husky voice? It is said that he began singing in earnest in his early 20s, before and after enlisting in the military. Around that time, he encounters James Ingram (1952~2019), which is like his musical base camp. Kim said that the soul singer's 'tone of voice' was so nice. He said he was fascinated by R&B and sang the song countless times. "I could not help myself but to sang and sang again," he said. It was not a reason that he sang that he would become a singer later. After graduating from Pukyong National University, he got a job at a company that makes advertising music. His interest was composition things. Still, he said that he just liked the soul music, so he shouted from time to time and studied by repeating songs. He said that after 10 years of doing so, he has come to have his own husky voice and singing skills today. The background he was introduced as ‘the hidden master’ in the broadcast can be guessed. Now, he ended the life of having no name and has become a singer who is loved by many people. How has he been after the public appearance? "I was pretty busy preparing a new album." He is mentioning of his new song, 'Beautiful as Today'. "I also filmed a video for sound recording, and I also responded to interviews with media companies." The song was composed by Lee Sang-gyu (ROZ), Park Joon-sik, and Baek Hyeon-soo, who made theme songs for KBS2 drama . Kim participated in the lyrics of this ballad song. The lyrics contain the autobiographical story of him through a difficult underground life. What kind of song is 'Beautiful as Today'? He said, "I received a lot of love unexpectedly through the broadcast program. Everyone is having a hard time these days, but I wanted to express my gratitude to everyone who gave me their love. With this song, I wanted to touch their hearts, comfort and support them." Let's savor the lyric. The road is faraway, seems there is no end in sight/ faint expectations and days without promises/ The clock is ticking I try to hold my mind saying start again. The sun that screams loud the wind that blows cold/ I ain't got an answer but the sad memories are beautiful as today' As you can see, Kim writes poetry well and sings well. Since he majored in design, he paints well.   When I asked him a word for pukyong students who are looking for their dreams, he laughed and said, "If they do like me, it would take more than 20 years to achieve their dreams, oh my gosh, what should I say?" He said, "Isn't it possible that you are majoring in design only to do design things for your entire life? I think any study is a process of finding one's dream. I hope there are many pukyong students who don't decide what they want to do at once, who don't wander by the stories of the people around them, and have various experiences." He said he would come over anytime if his alma mater calls him. By the time the cherry blossoms bloomed, I thought it would be nice if his husky voice echoed on campus.

Thesis on , 'the world's top 3 scientific journal'

 gave an eye to the research of next-generation display materials by PKNU professorThe research achievement of Prof. Lee Boram ... Presenting the result of improving the efficiency and stability of 'PeLED'   The National Research Foundation of Korea announced on March 11 that the paper 'Ligand-engineered bandgap stability in mixed-halide perovskite LEDs' by Professor Lee Bo-ram (Department of Physics) at Pukyong National University had been published in the international journal .This paper is attracting attention by presenting the result of greatly improving the luminous efficiency and color stability of the Perovskite Light-Emitting Device (PeLED), which is emerging as a next-generation display following the organic light-emitting device (OLED).As a material with high color purity and easy color adjustment, the 'metal halide (organic-inorganic-halogen type compound) perovskite' luminous body, which has the conditions for ultra-high-definition display, is attracting attention, but in fact, securing color stability was a problem.To obtain red and blue, two or more halides must be mixed, but they are easily separated by external stimuli which changes the luminous colors.Prof. Lee has significantly improved the external quantum efficiency from 4.1% to 20.3% in this study conducted with international joint research teams at Oxford University in the UK, Cambridge University, the University of Oregon, and includes Pukyong National University and UNIST in Korea, it succeeded in developing red PeLED, which also secured high color stability.Professor Lee's research team successfully removed defects in the nanocrystals by treating perovskite nanocrystals with two types of ligands (atoms or molecules bonded to the central atom in a coordination compound or complex compound) that chelate bonds to lead (Pb).Perovskite nanocrystals from which surface defects were removed through ligand treatment showed 1.5 times higher luminous efficiency (photoluminescence quantum efficiency) than nanocrystals with surface defects, and when nanocrystals were applied to a light emitting elements, the external quantum efficiency was found to be greatly improved from 4.1% to 20.3%. In addition, the ligand-treated perovskite nanocrystalline light emitting display showed high color stability with a constant emission spectrum when the device was activated.Professor Lee said, "Through this research, we expect that the commercialization of PeLED will be accelerated to enable more realistic colors and realistic expressions required in the increasingly developing VR and AR fields as well as in displays such as TVs."Especially, local academia highly praised the fact that this research achievement was achieved in an international joint research environment which had become more difficult due to Corona 19, and that research led by a local university in Busan was published in one of the world's top 3 major scientific journals.Professor Lee said, "Although the labs of overseas universities were closed due to Corona 19, and it was difficult for further experiments, it was resolved with active support from domestic researchers at places such as UNIST, Seoul National University, and Hanyang University. We were able to achieve good results by contacting overseas researchers through video meetings and conducting research."Professor Lee, who was appointed as a professor of the Department of Physics at Pukyong National University in 2017, has published more than 40 SCI-level papers after his appointment. Among them, he has published articles such as  as corresponding authors in eminent international journals. Currently, Professor Lee is actively conducting research activities with a total of 70 SCI papers related to research on optoelectronic devices such as light emitting displays and solar cells. He received a bachelor's degree from Ulsan University and a doctorate from UNIST.He said, "Although physics is a basic science, in the end, I think that research enriches life, so I am working on applied research based on basic science. Since the manufacturing mechanism of a light-emitting device that converts energy into light and a solar cell that converts light into energy have similar manufacturing mechanisms, this research can be applied any number of ways to improve the performance of solar cells and transistors. In the future, we will continue to do our best on valuable research that can be used in real life."Meanwhile, Professor Lee conducted his research with the support of the Basic Research (rising research) project from the National Research Foundation of Korea. Pukyong National University also plans to separately provide a reward fund in accordance with the award system for excellent papers.  △ A graph showing the electroluminescence wavelength stability of a device not treated with a ligand and a device treated with a ligand. △ Schematic diagram of ligand treatment on the perovskite surface
