This study explores the mobility patterns of Korean Early Study Aborad (ESA, hereafter) students in Singapore through a follow-up longitudinal case study, which was initially conducted about five years before this study. This study takes up transnational migration approach, focusing on family strategies and mobilization, which steered their mobility. Interviews with seven original families as well as 7 families additionally recruited in Singapore in 2012 were collected and analyzed by NVivo 9. In short, this study found that transnational mobility is composed of mobilities at global, regional and local levels. There were four types of mobilities; continuation of stay in Singapore, move from a third county to Singapore, return to Korea, and, what this research calls, fluid mobility. Examining the process of these mobilities shows that we need to consider at least three factors (performance of children's schooling; change of family circumstances; context of reception for both Singapore and Korea) as basic backgrounds. On this basis, the interplay between the context of receptions when aspirations for children's advancement by these transnational families made either facilitate or constrain their mobilities: contexts of Singapore and Korea may play a role of hurdle or trampoline. Also, local context of Singapore largely facilitate mobilities of Korean ESA families at both local and global levels.

The aim of this study is to measure the application of prone compression study using compression paddle for obese patients in upper gastrointestinal series. Prone compression study using compression paddle was performed in fifty patients, who were not examined completely erect compression study for obesity. The radiographs of stomach were classified into the lower, middle, and high body and then we gave five points included 'very poor', 'poor', 'suspicious', 'good', and 'complete' according to level of detection for area gastrica and mucosal fold. Statistic analysis was performed using T-test and ANOVA, and confidence rate was fixed in 95%(P<0.05) for the significance. The results were as follows : 1. The compression marks on high body was 'poor' grades in erect and prone compression study. The points were 1.64 and 1.86, respectively. 2. The compression marks on middle body was 1.68 in erect compression study, and 'suspicious' in prone compression study. 3. The compression marks on lower body was 'poor' in erect compression study, and 'good' in prone compression study. 4. There was a high statistic signification between the two study on middle and lower body except for high body(P<0.01). 5. The average abdominal thickness of subjects was 23.98 centimeter. There was no statistic signification between the difference of average marks by the abdominal thickness(P>0.05). As these results, the prone compression study in upper gastrointestinal serie seem to be an useful study for obese patients, because it decreases pain and the feeling of uneasiness, and improve compression efficiency remarkably.

국내에서 디자인 제 영역에 걸친 이론적이고 실제적인 학문적 탐구는 1979년 한국디자인학회 창립 이후 80년부터 시작된 디자인학 연구를 필두로 한다. 이때부터 학술교류를 통한 사회적 공헌 및 학문적 연구는 많은 성장을 이루었다. 본 연구에서는 지난 24년간 이루어진 디자인학 연구동향에 대한 분석을 위해 국내 대표 학회지인 ‘디자인학연구’와 ‘기초조형학연구’를 각 1호부터 최근호까지의 논문을 총 2065편 수집하였다. 논문분석을 통해 현재까지 이루어진 국내 디자인학연구의 현황을 조명하고 향후 연구방향을 ㅈ시하고자 함이 본 연구의 주 목적이다. 자료분석을 위한 통계적 기법으로는 빈도분석과 기술통계를, 그리고 유목의 관찰빈도와 기대빈도의 차이를 검증하기 위해 카이스퀘어($X^2$) 검증을 실시하였다. 검증결과 학술적 교류를 통한 디자인학의 역할이 증대되면서 연구논문의수가 꾸준히 증가하는 것을 알 수 있었고, 전체적인 분포현황은 디자인기반연구, 디자인응용연구, 디자인기초연구의 순으로 나타났다. 연구방법론에 있어서는 실증연구가 꾸준히 증가하였는데, 이는 디자인학이 객관적이고 과학적인 연구를 우해 커뮤니케이션학의 사회조사방법론을 많이 활용하기 때문이다.

논문에서는 python 언어를 학습하고자 하는 학생을 위한 학습 도우미 'PyStudy'를 개발하였다. 'PyStudy'는 콘솔창, 학습창, 학습 진도창, 파이썬 도움말, 학습콘텐츠로 구성되어 있다. 학생은 통상적인 통합개발환경(IDE) 기능과 학습콘텐츠들을 학습창을 통해 이용할 수 있다. 학습도중 모르는 것이 있을 경우 파이썬 도움말을 이용해 빠르게 찾을 수 있다. 학생의 학습관리는 학습 진도창을 통해 이루어진다. PyStudy는 파이썬 언어에 대한 효율적 학습환경을 제공하며, 이를 통해 파이썬 기반 고급 프로그래밍 교육에 적용할 수 있다.

본 연구는 수학영재학생들의 독립연구 수행 능력이 어떠한지를 알아보고, 수학영재담당 교사들은 독립연구를 어떻게 인식하고 있으며, 현재 독립연구와 관련하여 산출물 제작 실태는 어떠한지를 분석하여 추후 수학영재학생들의 독립연구 수행에 대한 연구의 기초를 제공하는데 그 목적이 있다. 독립연구는 영재학생들이 매우 선호하는 학습스타일로 교사와 함께 주의 깊게 계획되고 빈번히 점검되어 학생들이 자기주도적으로 수행할 때 연구기능 또한 신장된다. 본 연구는 수학영재학생 85명과 수학영재담당 교사 51명을 대상으로 조사연구방법으로 수행되었다. 연구결과 수학영재학생들의 독립연구 수행능력은 매우 낮은 편이었으며, 영재교육경험이 많고 적음에 따라, 교사 관여 없이 과제로 수행된 독립연구 경험의 유무에 따라 능력의 차이는 없는 것으로 나타났다. 또한, 수학영재담당 교사들은 독립연구의 필요성은 인식하나 독립연구 방법에 대한 이해가 부족한 것으로 나타났다.

Purpose: Laparoscopic proximal gastrectomy with double-tract reconstruction (LPG-DTR) is a function-preserving procedure performed for treating upper early gastric cancer (EGC). However, few studies have compared the outcomes of LPG-DTR with those of laparoscopic total gastrectomy (LTG). This study aimed at comparing the short-term outcomes of LPG-DTR between LTG and upper EGC. Materials and Methods: For upper-third EGC, a multicenter, prospective, randomized trial was performed to compare those who underwent LPG-DTR with those who underwent LTG. Short-term outcomes, including clinicopathologic results, morbidity, mortality, and postoperative courses, were evaluated using a full analysis set based on the intention-to-treat principle and the per-protocol set. Results: Of the patients, 138 who fulfilled the criteria were randomized to each group. One patient in the LPG-DTR group withdrew consent. Sixty-eight patients underwent LPG-DTR and 69 underwent LTG. The operative time (LPG-DTR=219.4 minutes; LTG=201.8 minutes; P=0.085), estimated blood loss (LPG-DTR=76.0 mL; LTG=66.1 mL; P=0.413), and the morbidity rate (LPG-DTR=23.5%; LTG=17.4%; P=0.373) between the groups were not significantly different. No mortality occurred in either of the study groups. Two weeks post operation, the Visick scores for postprandial symptoms, including reflux symptoms, were not significantly different between the groups (P=0.749). Laboratory findings on postoperative day 5 were not significantly different between the groups. Conclusions: The short-term outcomes of LPG-DTR for upper EGC were comparable to those of LTG.

This study emphasizes the everyday life study based on the proper study method. From the sociological literatures, everyday life's concept, it's various characteristics, two different perspectives and life-history approach are introduced. One Home Economics Paradigm Study published in 1996 is summarized to point out the importance of paradigm shift from quantitative method based on positivism to qualitative study for human everyday life study. I examined our everyday life studies as a reader and a member of screening committee and introduced four articles using different qualitative study methods.

This study is continuous with the study I (A Study on the Modeling) and the sample impeller of this study is defined by the modeling process of the exclusive CAD/CAM system developed in the study Ⅰ. And, this study describes a method for the 5-axis machining of impeller blades formed by ruled surface. Therefore, the exclusive CAD/CAM system is the software for modeling md machining of impeller blades. By using the machining method suggested in this study, we could manufacture impeller blades on 5-axis CNC machining center and the machined impeller was very agreeable to the designed impeller. Thus, theories proposed in this study can be very useful for the 5-axis machining of impeller blades.
