Improvement in prenatal ultrasonography is leading to diagnose choledochal cyst before birth and before onset of classical symptom more frequently. But, there is a controversy about optimal timing for Cyst excision of prenatally diagnosed asymptomatic choledochal cyst. To identify the most appropriate timing for surgery in prenatally diagnosed choledochal Cysts, we analyzed 6 patients who had operation for choledochal cysts within 30days after birth at the division of Pediatric Surgery, Samsung Medical Center and Inha University School of Medicine, from June 1995 to June 2002. Males were four and females 2, the mean age at operation was 11.2 days, and the median age 8.0 days. The range of gestational ages of the antenatal diagnosis of bile duct dilatation was 24 weeks to 32 weeks, mean was 38.3 weeks, and mean birth weight was 3,298.3 g. After birth, abdominal ultrasonography, hepatobiliary scintigraphy, and magnetic resonance cholangiopancratography (MRCP) were performed. Mean age at operation was 11.2 days. All patients had the cyst excision and Rouxen-Y hepaticojejunostomy. Immediate postoperative complication was not found. During the median follow-up period of 41 months, one patient was admitted due to cholangitis, and the other due to variceal bleeding. Early operative treatment of asymptomatic newborn is safe and effective to prevent developing complications later in life.

쿼드로터의 보장 비용 제어를 위한 T-S 퍼지 모델 접근법

최윤미(Yun-mi Choi),김도완(Do Wan Kim) 제어로봇시스템학회 2017 제어·로봇·시스템학회 논문지 Vol.23 No.7

This paper presents a Takagi-Sugeno (T-S) fuzzy model approach to the position and attitude control of a class of nonlinear quadrotor with the guaranteed control performance. The concerned cost performance index considers the revolutions per minute (RPM) to minimize the energy cost of the given quadrotor. By using the partial linearization and the sector nonlinearity, the error dynamics of quadrotor with respect to the position and the attitude is modeled in Takagi-Sugeno (T-S) form. Then, we derive sufficient conditions for the stabilization of error dynamics as well as the guaranteed control performance in the format of linear matrix inequality. A simulation is provided to show the effectiveness of the proposed methodology.

The aim of this study is to make it sure how pupils` science inquiry skills and attitude are influenced when they are taught by using the work-sheets for the differentiated learning according to their ability. In order to accomplish this aim, two classes of the fourth grade in the elementary school were distinguished into two groups: one was the experimental class and the other, the comparative class. The experimental class was given 52 hours of science lessons using the above sheets, and the comparative class, the general method of teaching. In order to compare their scientific interest and learning ability of the two groups each other, pupils were tested the standardized achievement in advance. The two groups were also given ex post facto test to measure the variation of their inquiry skills and attitude after the lessons. In addition, the experimental class was tested to measure their learning attitude after they are learned the science with the sheets. The results of this study are as follows: 1. According to the percentile statistics of the science inquiry skills test between the two groups, the work-sheets for the differentiated learning helped pupils develope their inquiry skills remarkably. 2. The work-sheets did not lead to significant difference between the learning ability of boys and girls. 3. The science lesson using the work-sheets showed positive influences in increasing pupils` scientific attitude. 4. About 77.2 percent of pupils accepted the excellent records of the evaluation in the science lesson using the sheets. It can be, therefore, concluded that the science lesson using the work-sheets for differentiated learning is one of effective science lessons to increasing pupils` science inquiry skills, compared with the general teaching method.

전시작전통제권 전환 정책에 대한 영향요인 분석: 세 가지 분석 수준을 활용한 주요 변수들의 영향력 평가

최윤미 ( Choi Yunmi ) 국방대학교 안보문제연구소 2019 국방연구 Vol.62 No.4

본 논문은 전시 작전통제권 논의 배경과 변천 과정을 고찰함으로써 정책결정 변화에 미치는 주요 요인들을 분석한다. 한국군의 전작권 전환문제는 1950년 6.25전쟁 발발 직후 유엔군 사령관에게 단일 지휘권이 이양되면서부터 시작되었고, 1978년 한미연합사령관에게 작전 지휘권이 전환된 이후 현재에 이르기까지 국내 정치적 이데올로기의 뜨거운 쟁점이 되어왔다. 그러나 전작권이라는 동일한 사안을 두고도 정부마다 문제 인식과 접근방법이 상이했으며, 첨예한 정치적 갈등과 대립 속에서 국민적 공감대까지 부진하여 전작권 논의는 전환-연기-재연기-조속한 환수 등 서로 다른 정책 결과와 변화를 가져왔다. 이러한 배경하에 본 논문이 제기한 연구 질문은 명료하다. 전작권 전환 결정을 변화시키는 근본적인 요인은 무엇인가? 한 국가의 정책결정 변수를 연구하는 데 있어 가장 유용한 분석의 틀로 손꼽히는 ‘세 가지 분석 수준(three levels of analysis)’을 활용하여 전작권 전환 결정에 변화를 미치는 주요 변수들을 파악해보고자 한다. 즉, 대통령 개인 또는 집권 정당의 정치적 이념을 포함한 개인적 수준, 북한 위협에 따른 국내 안보환경과 위협인식을 반영한 국가적 수준, 그리고 미국의 국제안보전략 변화에 따른 영향력을 고려한 국제체제 수준으로 구분하여 각각의 분석 수준에서 도출한 주요 변수의 영향력을 평가할 것이다. 본 논문은 전작권의 핵심 개념 및 변천과정을 되짚어봄으로써 전작권 전환이 내포한 내·외부적 갈등 요소들을 도출하고 정책결정 시 고려되어야 할 교훈을 도출하는데 이바지할 수 있을 것으로 기대한다. This paper seeks to explore the main factors affecting the policy-making changes on the transition of wartime operational control(OPCON) by examining the history of Korean OPCON. The issue of transferring wartime operational control of South Korean troops to the U.N. commander immediately after the outbreak of the Korean War in 1950, and has been used as a key base for forming the Korea-U.S. military alliance to the present day and a useful issue in terms of domestic political ideology since the establishment of the ROK-U.S. Combined Forces Command in 1978. However, the problem perception and approach of each government differed over the same issue of wartime operational control, and the discussion of wartime control resulted in different policy outcomes and changes, including the conversion-delay-reaction-quiet return as the public consensus remained sluggish amid sharp political conflicts and conflicts. Against this backdrop, the question of research in this paper is simple. What are the fundamental factors that change the decision to transfer wartime control? Using the “Three levels of analysis,” which is considered the most useful framework for studying a nation's policy-making variables, we want to identify the key variables that affect the decision to transfer wartime control. In other words, the influence of major variables derived at each level of analysis will be assessed, divided into personal levels, including the political ideologies of an individual president or a ruling party, national levels that reflect the domestic security environment and threat awareness due to North Korean threats, and international system levels that take into account the influence of changes in the U.S. international security strategy. Based on the core concept of wartime operational control and internal and external conflict factors that the transfer of wartime control implies, the government will provide policy suggestions on the challenges of achieving a solid Korea-U.S. alliance after the transfer of wartime control.

한국 평화유지활동(PKO)의 새 지평

최윤미(Choi, Yunmi) 한국전략문제연구소 2016 전략연구 Vol.68 No.-

전쟁방지와 국제평화유지를 목적으로 설립된 유엔은 2015년 70주년을 맞이하였다. 더욱 강해진 유엔의 역할과 임무를 위해 유엔 평화활동 보고서가 새롭게 발간되었고 미래에 전개될 평화활동 동향에 국제사회의 이목이 집중되었다. 본 연구는 여성의 역할과 참여확대 방안이 새로운 세대를 준비하는 유엔 평화활동 논의의 핵심이 될 것이라는 전망을 바탕으로, 한국 평화유지활동의 개혁과제를 성인지적 통합과 여성참여 확대를 중심으로 고찰하였다. 국제평화와 안보분야에 있어서 여성의 역할은 중차대한 의제로서 유엔 안보리 결의안 1325호를 통해 그 중요성이 다각적으로 입증되었고, 제도적 · 정책적인 지원 하에 국제분쟁해결의 근본적인 대안으로 떠오르고 있다. 이러한 국제적인 변화와 개혁의지에도 불구하고, 국내적으로 관련 연구나 문헌들이 전혀 이루어지지 않았다는 문제의식에서 출발하여, 본 논문은 관련 의제에 관한 중요성 및 국제 논의동향에 대해 소개하고, 대한민국 평화유지활동의 새로운 패러다임 전환을 도모하고자 하였다. 이를 위해 다음의 세 가지 핵심 연구질문을 중심으로 논의가 전개되었다. 유엔 평화활동의 새로운 개혁과제의 핵심은 무엇인가? 성인지적 관점에서 평화활동의 여성참여 의미와 한계는 무엇인가? 한국 평화유지활동의 발전을 위해 여성인력을 활용할 수 있는 방안은 무엇인가? 국제동향 분석을 통한 연구 결과, 한국 평화유지활동의 발전을 위해서 첫째, 유엔안보리 결의안 1325호 이행을 위한 대한민국 국가행동계획의 현실화, 둘째, 평화활동분야 여성전문가 육성을 위한 구체적인 방안 모색, 셋째, 후속세대 양성을 위한 교육 추진, 넷째, 평화유지활동과 성인지 관점의 통합 등을 전략적 함의로 제시하였다. The year 2015 marked the 70th anniversary of the United Nations (UN) of which foremost purpose is to maintain international peace and security. It was also remarkable that the High-Level Independent Panel on Peace Operations (HIPPO) released the most comprehensive assessment of UN peace operations since the Brahimi Report issued in 2000. The HIPPO report put forward more than 100 recommendations for developing and improving UN peace operations, followed by the Secretary-General’s agenda outlining priorities and actions to make UN peace operations fit for purpose. Of the essential shifts to UN peace operations called for in the HIPPO report, this study primarily focuses on the gender perspective and seeks to scrutinize women’s role and participation in peace operations. UNSC Resolution 1325 on women, peace and security is often called a landmark resolution, because it both reaffirmed the importance of women’s participation and involvement at all levels of the peace and security agenda and called for the member states to incorporate a gender perspective into peacekeeping operations. Despite ongoing initiatives and essential agenda setting for peace operations at international UN level, it seems that such key aspects and reforms have not been sufficiently echoed at domestic level in Korea. Hence, recognizing significant lack of domestic understanding and awareness as well as the absence of related existing studies on women and peacekeeping, this paper seeks answers to the following three research questions: what are the new aspects of reform and strategies for the future of the UN Peace Operations?; what does a gender perspective signify in the specific realm of UN peace operations, and how can the issue overcome major hurdles ahead?; and what is a lesson learned to develop and refine the ROK’s peacekeeping operations? The study concludes by suggesting four essential aspects for the shaping of a new horizon of ROK’s PKO: paying special attention to active implementation of the National Action Plan on UNSCR 1325, making great efforts to promote and increase women’s participation in peacekeeping at both political and operational levels, nurturing and educating young female peacekeepers and peacekeeping officials, and incorporating gender perspective into peacekeeping operations.

Background/Aims: This study was carried out to evaluate prognostic significance of the clinicopathological features in colorectal cancer. Methods: The records of 413 patients who underwent a curative resection of colorectal cancer from June of 1996 to December of 2000 were examined focusing on the clinicopathological factors and difference of survival rates. Results: The numbers of lymph node metastasis were significantly related to age, depth of invasion, histologic differentiation, tumor size, lymphovascular invasion, perineural invasion, and preoperative serum CEA level. In the univariate analysis for 366 patients, the depth of invasion (p=0.0017), histologic differentiation (p=0.0069), lymph node metastasis (p=0.0000), lymphovascular invasion (p=0.0001), perineural invasion (p=0.0008), and preoperative serum CEA level (p=0.0005) turned out to be significant prognostic factors. The histologic differentiation between the primary lesion and the metastatic lymph node was the same in 90.7% of the studied cases. Capsular invasion was found in 92 cases (53.5%), but there was no significant difference in survival rates between the capsular invasion group and non-capsular invasion group (p=0.0510). Conclusions: In this study, the depth of invasion, lymph node metastasis, and the number of lymph node metastasis could be recognized as important prognostic factors for colorectal cancer. However, further follow-up studies are needed to determine the role of the various clinical and pathological factors in colorectal cancer prognosis. (Korean J Gastroenterol 2002;40:371-378)
