Comprehensive Analysis on Wrinkled Patterns Generated by Inflation and Contraction of Spherical Voids

임민철,박재윤,정지훈,김봉수,김영록,정운용 한국정밀공학회 2018 International Journal of Precision Engineering and Vol.5 No.5

We comprehensively investigated the wrinkles of a stiff layer covering a spherical void embedded in a rubber matrix after the void experienced inflation or contraction. We developed an easy experimental way to realize the inflation and contraction of the voids. The inflation took place in a void right beneath the surface of the matrix and the contraction happened in a void at the bottom of the rubber matrix. In the inflation, the wrinkle at the center of the deformation was random, and the pattern propagated into rabyrinthine, herringbone, and then oriented parallel lines as the position was away from the center of the inflation to the edge. The cracks were concentric, which were perpendicular to the parallel wrinkled pattern. In the contraction, the wrinkle was simply concentric around the surface of the void without any crack. The cracks were found only near the center of the deformation. The strain distribution in the stiff layer after the inflation and contraction was theoretically analyzed with simulations that were in excellent agreement with the experimental results.

폴리다이아세틸렌(Polydiacetylene) vesicle의 크기에 따른 색전이 특성 연구

임민철,이재은,김영록 慶熙大學校 食糧資源開發硏究所 2010 硏究論文集 Vol.29 No.-

Conjugated polydiacetylene (POA) vesicles have been intensively investigated as smart sensing materials due to its unique optical properties. POA vesicles change visible color from blue to red under extemal stimuli such as temperature, pH, solvent, and mechanical stress. A variety of methods to increase the sensitivity in polydiacetylene systems like variation of carbon chain length, polymerization temperature and strength of UV irradiation were previously reported. In this study we investigated the effect of color transition of POA vesicles according to vesicle size by extrusion technology with different pore size. The degree of color change was quantified by UV -vis spectrophotometer. In order to quantify the response of POA vesicles to the temperature, colorimetric response (CR%), represents degree of color change from blue to red, was used

The purpose of the present study was to investigate me effects of Hyunhosaiksan (HHS) on antithrombotic actions which include blood activation, thrombus removal, warming of circulating blood, and the control of pain on abdomen and lower and upper burning spaces. HHS significantly inhibited platelet aggregation induced by ADP and epinephrine in a HHS dose-dependent manner when analyzed by me Sigmoid Emax model in WinNonlin EC5O values of HHS were 1.71 μg/ml and 0.004 μg/ml for ADP and epinephrine respectively. In the vivo study, HHS inhibited pulmonary embolism induced by collagen and epinephrine, which was however statistically insignificant. HHS increased number of platelets, APTT and volume of fibrinogen significantly as compared with the control group in dextran-induced thrombus model. Furthermore, HHS stimulated levels of blood flow in vivo though its effect was not observed in vitro. These results suggest that Hyunhosaiksan (HHS) can be used for treating numerous diseases related with blood aggregation and circulation problems. Further systematic investigations on the synergic effects among drugs used in the oriental medicine as well as in me western medicine in relation to thrombosis therapy would provide an important insight into the potential therapeutic applications.

식중독균의 검출을 위한 시료전처리 및 핵산기반의 분석기술

임민철,김영록 한국산업식품공학회 2017 산업 식품공학 Vol.21 No.3

There have been great efforts to develop a rapid and sensitive detection method to monitor the presence of pathogenic bacteria in food. While a number of methods have been reported for bacterial detection with a detection limit to a single digit, most of them are suitable only for the bacteria in pure culture or buffered solution. On the other hand, foods are composed of highly complicated matrices containing carbohydrate, fat, protein, fibers, and many other components whose composition varies from one food to the other. Furthermore, many components in food interfere with the downstream detection process, which significantly affect the sensitivity and selectivity of the detection. Therefore, isolating and concentrating the target pathogenic bacteria from food matrices are of importance to enhance the detection power of the system. The present review provides an introduction to the representative sample preparation strategies to isolate target pathogenic bacteria from food sample. We further describe the nucleic acidbased detection methods, such as PCR, real-time PCR, NASBA, RCA, LCR, and LAMP. Nucleic acid-based methods are by far the most sensitive and effective for the detection of a low number of target pathogens whose performance is greatly improved by combining with the sample preparation methods.

스마트-해섭(Smart-HACCP) 적용을 위한 식품안전 검시기술 동향

임민철(Min-Cheol Lim),우민아(Min-Ah Woo),최성욱(Sung-Wook Choi) 한국식품과학회 2021 식품과학과 산업 Vol.54 No.4

식품안전사고는 2009년 이후 해마다 5천건 이상 매년 2%씩 증가하고 있는 추세이며 환경오염 및 농수산물 원산지표시 위반 등이 증가하고 있어 먹거리 안전에 대한 국민 불안은 가중되고 있는 실정이다. 식품안전사고를 예방할 수 있는 가장 좋은 방법은 빨리 검사하는 방법이라고 대부분 알고 있지만 식품생산 및 유통 현장에 분석 비전문가 수준에서 활용할 수 있는 검사기술이 부족한 실정이다. 최근 현장진단기술 중 시료에서 검사까지 가능한 STA 기술을 중심으로 유전자 기반 식중독균을 검사하는 방법에 대해 소개하였다. 사람이 아닌 원격지 무인으로 식품위해인자를 직접적으로 검사하여 식품안전정보를 위변조 없이 생성할 수 있다면 현재의 빅데이터와 인공지능 기술로부터 보다 정확한 위험을 예측할 수 있어 오염원을 관리할 수 있다. 이러한 정보 처리는 현재 클라우드 기술을 이용하여 스마트폰에서도 활용 가능한 수준이기 때문에 영세사업장이나 공공 단체급식 등에 활용 가능할 것으로 판단된다. Food safety accidents have been increasing by 2% over 5,000 cases every year since 2009. Most people know that the best method to prevent food safety accidents is a quick inspection, but there is a lack of inspection technology that can be used at the non-analytic level to food production and distribution sites. Among the recent on-site diagnostic technologies, the methods for testing gene-based food poisoning bacteria were introduced with the STA technology, which can range from sample to detection. If food safety information can be generated without forgery by directly inspecting food hazard factors by remote, unmanned, not human, pollution sources can be managed by predicting risks more accurately from current big-data and artificial intelligence technology. Since this information processing can be used on smartphones using the current cloud technology, it is judged that it can be used for food safety to small food businesses or catering services.

청소년의 학습적 능력믿음, 지각된 유능감, 내적 동기 간의 구조모형 검증

임민철(MinChul Lim) 마인드교육융합학회 2023 마인드 교육 Vol.2 No.1

본 연구는 그동안 스포츠 선수들에게 주로 적용되어 왔던 능력믿음을 청소년의 학습에 적용해봄으로써 효과적인 학습방법 개발에 일조하는 것에 목적을 둔다. 연구자는 학습에 대한 청소년들의 능력믿음이 지각된 유능감과 내적 동기에 어떠한 영향을 미치는지 다섯 가지 가설을 설정하여 350명의 고등학생을 대상으로 사회과학적 연구를 진행하였다. 연구 결과, 다음과 같은 사실을 확인할 수 있었다. 첫째, 학습에 대한 능력믿음 중 고정된 믿음이 높으면 지각된 유능감이 낮아진다. 둘째, 학습에 대한 능력믿음 중 증가된 믿음이 높으면 지각된 유능감이 높아진다. 셋째, 지각된 유능감이 높으면 내적 동기가 강해진다. 넷째, 증가된 믿음이 높으면 내적 동기가 강해진다. 이러한 연구 결과는 증가된 믿음을 높여줌으로서 결과적으로 학습능력을 향상시킬 수 있다는 것을 제시해준다. 이는 현재의 성적, 주변 환경, 경험 등과 상관없이 학생들의 내면으로부터 ‘나는 할 수 있는 사람’이라는 믿음을 형성시켜준다면, 이것이 지각된 유능감 및 내적 동기를 높여 가시적인 성적 향상으로 이어질 수 있다는 것을 의미한다. This study aims to contribute to the development of effective learning methods by applying ability beliefs that have been mainly applied to sports athletes to youth learning. The researcher conducted a social science study on 350 high-school students by setting five hypotheses on how ability beliefs in learning affect perceived competence and intrinsic motivation. As a result of the study, the following facts were confirmed. First, if the entity belief about learning is high, the perceived competence is lowered. Second, if the incremental belief about learning is high, the perceived competence increases. Third, when perceived competence is high, intrinsic motivation is strong. Fourth, if the incremental belief is high, the intrinsic motivation is strong. These research results suggest that learning ability can be improved as a result by increasing incremental beliefs. This means that if students believe that “I can do it” regardless of their current grades, surroundings, and experiences, this can lead to visible performance improvement by increasing perceived competence and intrinsic motivation.

비오 2세의 『비망록』 -15세기 휴머니스트 교황의 자기변론서-

Pope Pius Ⅱ(1458∼1464) was a well known humanist, also famous as a poet and orator. In 1462 he began writing Commentaries, a memoire of his life and work as a Pope. The title and structure of the book was derived from the ancient genre of Commentarii, which was the Italian literary trend of the Renaissance era. Scholars usually regard the Commentaries as “the only autobiography ever written by a reigning Pope” and also focus on the book`s political propagandistic character, similar to that of the ancient genre Commentarii. However, to fully understand the Commentaries, an approach in the direction of the author needs to be made. This means that to fully understand the historical context of the Commentaries, one needs to consider Pius Ⅱ`s personal life and the situation of the Fifteenth-century Christendom under the Ottoman invasions. The ‘anxiety’ which sprang from the conflict between Pius Ⅱ`s old universalism ideal and the awareness of the Papal authority failing, was an important factor in why this book was written. This study focuses on the ‘apologia’ character of the Commentaries, which aims to defend Pius Ⅱ`s failures in the crusading policies in the earlier years of his reign. His own description of his youth, conclave of 1458 and early years of his reign in Commentaries are further discussed. Nevertheless, Commentaries does not really concern itself with historical preciseness. Rather, how Pius Ⅱ reconstitutes historical facts to defend himself was one important point of this study. Pius Ⅱ selected certain facts and reorganized them in such a fashion to favorably describe his life and his work. This study argues that Pius Ⅱ wrote his book with readers in mind, and that the Commentaries is a result of his awareness of the public`s eye.

청소년의 리더십생활기술 교육 방안 연구

임민철(Minchul Im) 마인드교육융합학회 2022 마인드 교육 Vol.1 No.2

The purpose of this study is to help develop effective leadership life skills education plans through looking at how biblical figures can be used when educating leadership life skills for teenagers. Moreover, I would like to pioneer a new research field by converging and applying the characteristics of Christian leaders, which are strong beliefs, future orientation, sacrifice, humility, and serving, to general leadership research. For the purpose of the study, the theoretical background was first established through Previous studies related to leadership life skills and Bible-based pedagogy. Then, Moses, Joseph, David, and Apostle Paul, the representative leaders in the Bible, were selected to examine how the factors of leadership life skills were expressed and how they affected their members. Each scholar presents various sub-factors of leadership life skills, but four factors were selected as the subjects of this study, including two internal factors and two external factors. As the next step, the characters in the Bible who presented the selected sub-factors of leadership life skills were suggested. Finally, the study showed how each of the character gained the leadership life skills, how they led others successfully, and how the results were changed through their leadership. Through this study, we found that the Bible is worth using as a positive educational content in educating adolescents on leadership life skills. The reason is that, first, Christians account for about one-third of the Korean people. Due to the religious nature, education based on common beliefs is bound to be highly effective. Second, the Bible has a value as a historical book in addition to its religious value. It can be a desirable way to educate leaderships that adolescents should have in the future through the leadership of historical figures. Third, the Christian spirit can be the basis for effective leadership. Christianity basically encourages people to have a humble mind by discovering their own inadequacies in front of God, and teaches them to respect others without easily judging them by their own standards. Fourth, the Bible describes various kinds of leaders in great detail. The process by which successful leaders acquire leadership life skills and the results when acquired leadership is expressed are recorded in the Bible in detail. Through these narratives, modern researchers would be able to approach and draw the ideal leadership life skills from various angles. Considering that the relationships between past and present and between present and future are repeated and developed, a new research field will be created if Christian leadership and leadership life skills studied in general social science can be fused and complemented. Therefore, Christian leadership must differentiate its own unique characteristics. At the same time, this should be accompanied by general leadership research to the extent applicable to youth education through social science methods such as interviews, statistics, and quantification. This leaves a task to be studied further in the future. I hope that this study will help educate adolescents about the values of faith, trust, consideration, and service necessary for modern society beyond religion. 이 논문의 목적은 청소년을 대상으로 리더십생활기술을 교육함에 있어 성경의 인물들이 어떻게 적용될 수 있는지를 살펴봄으로서 효과적인 리더십생활기술 교육 방안 개발에 일조하고자 함이다. 더불어 기독교리더십이 가지는 특징, 즉 강한 신념, 미래지향성, 희생, 겸손, 섬김 등의 모습들을 일반적인 리더십 연구 분야에 융합 적용함으로서 새로운 연구의 장을 개척하고자 한다. 이를 위해 먼저 리더십생활기술, 그리고 성경과 현대교육에 관련된 선행연구들을 통해 이론적 배경을 정립하였다. 이어 성경 속 대표적 지도자인 모세, 요셉, 다윗, 사도바울 선택하여 이들을 통해 리더십생활기술의 요인들이 어떻게 발현되고 구성원들에게 어떠한 영향을 미쳤는지를 살펴보았다. 학자마다 리더십생활기술의 다양한 하위 요인을 제시하지만, 대체로 공통적으로 언급하는 요인 중 중 인간관계기술, 자기이해기술의 내면적 요소 2가지, 의사결정기술, 그룹활동기술의 외부적 요소 2가지 총 4가지 요인을 본 연구의 대상으로 선정하였다. 그리고 선정된 리더십생활기술의 요인들이 잘 발현되는 성경 속 인물과 발현 과정 및 그 결과를 각 요인과 매치하여 구체적으로 제시하였다. 본 연구를 통해 우리는 성경이 청소년들에게 리더십생활기술을 교육함에 있어 긍정적인 교육 콘텐츠로서 활용 가치가 있음을 보았다. 그 이유는 첫째, 기독교인이 우리나라 국민의 약 1/3을 차지한다는 점이다. 종교적인 특성상 공통된 믿음과 신념을 바탕으로 하는 교육은 효과가 높을 수밖에 없다. 둘째, 성경이 종교적 가치 외에 역사서로서의 가치도 지닌다는 점이다. 역사적 인물들의 리더십을 통해 미래 청소년들이 가져야 할 리더십을 교육하는 것이 바람직한 방법이 될 수 있다. 셋째, 기독교 정신이 효과적인 리더십의 바탕이 된다는 점이다. 기독교는 기본적으로 신 앞에 자신의 부족함을 발견하여 낮은 마음의 자세를 가지도록 권유하고, 자신만의 기준으로 타인을 쉽게 판단하지 않고 존중하도록 가르친다. 넷째, 성경에는 다양한 종류의 지도자들이 매우 상세히 묘사되어 있다는 점이다. 성공한 지도자들이 리더십생활기술을 습득하게 되는 과정과 습득된 리더십이 발현되었을 때의 결과가 상세히 기록되어 있으며 이러한 서사를 통해 현대 연구자들은 이상적인 리더십생활기술의 모습을 다양한 각도에서 접근하고 그려볼 수 있을 것이다. 과거와 현재, 그리고 현재와 미래가 유기적 관계 속에서 반복 및 발전된다는 점을 고려할 때, 성경을 바탕으로 하는 기독교적 리더십과 일반 사회과학 속에서 연구되는 리더십생활기술이 상호보완적 관계 및 융합학문으로서의 관계를 이루어나갈 수 있다면 지금까지의 연구와는 다른 새로운 연구의 장이 만들어질 수 있을 것이다. 그러므로 기독교리더십은 일반 리더십과의 공통점과 함께 기독교 리더십만의 고유한 특성들을 차별화함과 동시에 인터뷰, 통계, 수치화 등의 사회과학적 방법을 통해 실생활 및 청소년 교육에 적용 가능한 범위 내에서 연구되어야 할 것이며 이는 앞으로 더욱 연구되어야 할 과제를 남긴다고 할 수 있다. 본 연구가 종교를 초월하여 현대사회에 필요한 믿음과 신뢰, 배려와 섬김의 가치를 청소년에게 교육하는 데 일조하기를 바란다.
