윤민영,최윤미,최선근,김세중,안승익,김경래 연세대학교의과대학 2010 Yonsei medical journal Vol.51 No.5

Paraduodenal hernias are a rare congenital malformation, but they are the most common internal hernias. They develop secondary to a failure in midgut rotation,which may lead to small bowel obstruction or other clinical manifestations. The authors recently experienced a case of a left paraduodenal hernia presenting with unusual symptoms of left flank pain and vomiting.

The purpose of this study is to examine the effects of differential association, definitions, and low self-control variables to victim-offender overlap in the juvenile cyber crime, based on the “Self-Control Theory” and “Differential Association Theory”. This study used the data collected for “A Study on the Types and Countermeasures of Youth Cyber Violence” reported by Korean Institute of Criminology(KIC) in 2015. Cross tabulation, analysis of variance, and multinomial logistic regression were conducted to test the hypothesis. First, it turns out that there is victim-offender overlap in the juvenile cyber crime. Second, the results of multinomial logistic regression analysis showed that unlike self-control theory explaining every group’s differences, differential association theory explains differently according to detailed factors. Therefore, if a new juvenile cyber crime prevention policy is established based on differential association theory in the future, we suggest policy makers to consider the subject of prevention policy whether he/she was committed a crime or victimized before. 그동안 사이버범죄는 지속적으로 증가해 왔으며, 특히 코로나-19라는 상황적 요인으로 인해 그 증가폭이 더 커졌다. 본 연구는 인터넷 사용이 활발한 청소년들을 대상으로 사이버범죄의 가해·피해 중첩성에 영향을 미치는 요인에 대해 조사하였다. 한국형사정책연구원에서 수집한 ‘청소년 대상 사이버 폭력 인식조사’ 2015년도 자료를 활용하였으며, 자기통제이론과 차별적 접촉이론을 근거이론으로 하였다. 먼저 교차분석을 진행한 결과, 일반적인 청소년범죄와 마찬가지로 청소년 사이버범죄에서도 가해-피해경험 간의 중첩성이 확인되었다. 다음으로 다항 로지스틱 회귀분석을 실시한 결과 독립변수 중 낮은 자기통제는 가해경험, 피해경험, 중첩경험의 가능성을 높이는 것으로 나타났다. 차별접촉은 참조집단이 무경험 집단인 경우 중첩경험과 가해경험의 가능성을 높였으며, 범죄우호적 정의는 참조집단이 무경험 집단 또는 피해집단인 경우 중첩경험의 가능성을 높이는 것으로 확인되었다. 이러한 결과를 바탕으로 청소년 사이버범죄 예방정책 수립에 있어 교육대상자에 따른 차별화된 정책의 수립 필요성을 제시하였다.

The Traveling Salesman Problem (TSP) is a well-known NP-Complete problem. In the TSP, the salesman would like to visit each city while minimizing the cost of traveling among all the cities. He only visits a city once and returning to where he began after visiting all the cities. A genetic algorithm is an adaptive search technique based on the principles and mechanisms of 'natural selection' and 'survival of the fittest' from the natural evolution. A genetic algorithm can effictively search the problem domain and easily solve complex problems. This paper proposes the application of the genetic algorithm to the Traveling Salesman Problem using the edge recombination method.

Simulated annealing and genetic algorithms represent powerful combinatorial optimization methods with complementary strengths and weaknesses. Because trade-offs exist between these two classes of algorithms, there is an interest in identifying hybrid methods that combine features of both simulated annealing and genetic algorithm and exhibit performance superior to either method alone. In this paper, a new method that combines the recombinative power of genetic algorithm and annealing schedule of simulated annealing is presented. The new algorithm inherits those aspects of genetic algorithm that lend themselves to parallelization, and avoids serial bottlenecks of genetic algorithm approaches by incorporating elements of simulated annealing to provide a completely parallel, easily scalable hybrid genetic/simulated annealing method. The new method does not require parallelization of any problem-specific portions of a serial implementation.

Brief Review of Atomic Layer Etching Based on Radiofrequency-Biased Ar/C4F6 -Mixture-Based Inductively Coupled Plasma Characteristics

윤민영,염희중,정종렬,김정형,이효창 한국진공학회 2023 Applied Science and Convergence Technology Vol.32 No.2

Among the next-generation semiconductor manufacturing processes, plasma-assisted atomic layer etching (ALE) has garnered significant attention along with an increase in demand for damage-free and precise process technology. In typical ALE, an atomic layer is etched in each cycle by repeating a modification step through a chemical reaction using a reactive gas and a removal step through physical etching. Polymer-rich fluorocarbon gases, such as C4F8 and C4F6, are generally used as reactive gases for ALE to protect the sidewalls of high-aspect-ratio patterns. Compared with C4F8, C4F6 has a lower global warming potential and an excellent etch selectivity, thus, it can be a candidate for next-generation etching gas. Among the plasma sources for ALE, inductively coupled plasma (ICP) is widely used because of its low plasma potential and low electron temperature. Moreover, the ion energy and electron density in an ICP can be independently controlled using an additional bias system. In ALE performed using a radiofrequency (RF)-biased ICP, the plasma characteristics change in each step, because the reactive gas is injected and purged in the modification step, and a bias is applied in the removal step. Hence, an ALE process design or a recipe tuning based on an understanding of the plasma characteristics in each step is required for precisely controlling the process. This review introduces and discusses ALE process and plasma characteristics using RF-biased ICP and C4F6 (Hexafluoro-1,3-butadiene).

Transcriptomic profiling of soybean in response to UV-B and Xanthomonas axonopodis treatment reveals shared gene components in stress defense pathways

윤민영,김문영,이재언,이태영,김길현,하정민,김용환,이석하 한국유전학회 2017 Genes & Genomics Vol.39 No.2

Soybean (Glycine max [L.]) has evolved to survive under abiotic and biotic stress conditions by utilizing multiple signaling pathways. Although several studies have revealed shared defense signaling pathways in plants, the majority of components at the convergence points of signaling pathways triggered by both abiotic and biotic stress remain poorly understood. Here, we profiled the overall transcriptional responses of soybean to two different types of stress using the UV-B-resistant cultivar, Buseok, and the UV-B-sensitive cultivar, Cheongja 3, as well as two near isogenic lines carrying bacterial leaf pustule (BLP) diseaseresistant and -susceptible alleles. We compared transcript abundance and identified genes that commonly respond to UV-B stress and BLP disease. In addition, we surveyed the co-localization of differentially expressed genes (DEGs) and their paralogs with abiotic and biotic stress-related quantitative trait loci (QTLs) on the soybean genome. Among 14 DEGs that respond to both stresses, five DEGs are involved in the jasmonic acid (JA) metabolic pathway, encoding Jasmonate ZIM (Zinc-finger protein expressed in Inflorescence Meristem) domain-containing protein 1 (JAZ 1), a negative regulator of JA signaling. Two DEGs for JAZ 1 were co-localized with biotic stress-related QTLs. One DEG encoding the stress-induced protein starvationassociated message 22 and its two paralogs were co-localized with both abiotic and biotic stress-related QTLs. The results of this study help elucidate general responses to abiotic and biotic stress in soybean, thereby helping breeders improve stress-resistant soybean cultivars.
