Objectives: This study was performed to identify the associations of empowerment and social capital (such as social participation and trust) with self-rated health in Korean communities with poor health. Methods: This study used the data from community health interviews conducted at 29 administrative sections (dong, eup, or myeon) with high mortality from August to October in both 2010 and 2011 as part of the Health Plus Happiness Plus Projects in Gyeongsangnam-do Province. The study subjects comprised 6,383 individuals composed of approximately 220 adults randomly sampled from each administrative section. The empowerment was measured with five-point Likert scale responses to seven perceived control questions (two at the individual level, five at the community level). The social participation was measured with 'participation in formal and/or informal group' and trust using responses to three questions about trust of others. Results: The high empowerment scores at both individual and community levels, social participation in informal groups, and high trust level had independent and significant associations with good self-rated health after adjusting for socio-demographic factors (sex, age, marital status, occupation, and food affordability) and health behaviors (smoking, alcohol drinking, and exercise) in the logistic regressions. There were weak but significant associations among empowerment, social participation, and trust levels. Conclusions: Empowerment, social participation, and trust were weakly inter-related and significantly associated with self-rated health. More studies are warranted for empowerment and other social capital indices in health promotion.

Purpose : To analyze organization variables related to nursing between the doctors' strike and normal periods. Methods : The sample consisted of 1,220(600 for doctors' strike and 620 for normal periods) nurses working in 5 hospitals. Six instruments were used for data collection including Job Activity Scale(JAS; Laschinger, 1994), Organization Relationship Scale(ORS; Laschinger, 1994), Interpersonal Support Scale(developed by Firth et al., 1986 and revised by Ahn(2000), Self-efficacy Scale(Riggs & Knight, 1994),Job Satisfaction Scale(Slavitts et al., 1978), and Organizational Commitment Questionnaire(OCQ; Mowday et al., 1979). Results : There were significant differences among variables(i.e., formal power, interpersonal support, self-efficacy and organizational commitment)between doctors' strike and normal periods. The formal power was high during the normal period, however interpersonal support, self-efficacy and organizational commitment were high during the doctors' strike. Conclusion : Interpersonal support, self-efficacy and job satisfaction were change by working conditions, but organizational commitment was not changed by working conditions.

The purpose of this study was to analyze the effect of childcare teachers' empowerment on affective commitment. For that, a survey was conducted of childcare teachers working at private-sector childcare facilities located at S City of Jeollanam-do. Data collected from 247 questionnaires were used for analysis, excluding those containing insincere answers. The collected data were investigated using SPSS 18.0, a statistical program, through reliability analysis, confirmatory factor analysis, t/F-test, Scheffe post-hoc test, and hierarchical regression analysis. Major results of analysis were as follows: A difference in affective commitment was observed, depending on age and remuneration, the demographic characteristics of childcare teachers. Hierarchical regression analysis was conducted by factoring in each sub-variable of empowerment with demographic characteristics of childcare teachers being controlled. Among the empowerment variables of childcare teachers, significance, capability, and self-determination were found to have an effect on affective commitment. Meanwhile, the extent of influence did not have any effect on affective commitment. Finally, the variable that had the greatest effect on affective commitment of childcare teachers was significance among empowerment variables.

This study analyzes the relationship between NGOs and government assisting defecting North Korean residents and seeks a desirable model of a linkage between the two sectors. The factors used in this study for an analysis of the relationship between NGOs and government are frequency and direction of interaction between NGOs and government, government's acceptance or resistance of institutional pluralism. the degree of formality of the relationship, and the relative power balance in the relationship. Also, Coston's typology(l998) of NGO-government relationships is applied for the analysis. Results of the analysis indicates that, in resettlement assistance for defecting North Korean residents, Korean NGOs and government have a cooperative relationship at minimal level, which means that there is a low linkage, informal relationship, and asymmetrical power-relationship between the two sectors. Also, government's acceptance of institutional pluralism seems to be superficial and a tendency of one-way direction of interaction is identified. Based on the findings, this study suggests a more collaborative relationship or partnership between NGOs and the government to arrange more effective assistance programs and activities. Discussion of some controversial issues related to achieving the collaboration and suggestion of a possible model of linking government to the NGOs are followed in conclusion.

초등학교의 컴퓨터교육은 국가에서 발표한 정보통신기술교육 지침에 의해서 이루어지고 있다. 지금까지는 이 지침이 소프트웨어 활용에 치중하였던 관계로 초등학교 현장에서 이루어지는 정보통신기술교육의 비판 중 하나는 제7차 교육과정에서 강조하는 문제해결력, 창의력 등 고등 사고능력을 기르는 교육이 되지 못하고 워드프로세서, 파워포인트, 엑셀 등 주로 응용 소프트웨어를 다루는 교육에 치중해 왔다는 것이다. 2005년 12원에 발표된 초 중등학교 정보통신기술교육 운영지침에는 문제해결능력을 기르기 위한 논리적 사고력 향상을 위하여 초등학교 단계에서 프로그래밍 교육이 이루어져야 함을 공식적으로 밝히고 있다. 그러나 초등학교 현장에서 이러한 프로그래밍 교육을 시행할 때 어떠한 도구와 내용을 갖고 어떻게 교수해야 하는지에 관한 구체적인 연구가 없다. 본 논문에서는 초등학교 프로그래밍 교육을 위한 구체적이고 현실적인 방법으로 QBASIC 기반 프로그래밍 교육과정을 설계하였다.

This paper introduces a novel system-level framework that derives energy efficient electric vehicle (EV) driving speed profile to extend EV driving range without additional cost. This paper first implements an EV power train model considering forces acting on a driving vehicle and motor efficiency. Then, it derivate the minimum-energy driving speed profile for a given driving mission defined by the route. This framework first formulates an optimization problem and uses the dynamic programming algorithm with a weighting factor to derive a speed profile minimizing both of energy consumption and driving time. This paper introduces various weighting factor tracking methods to satisfy the driving time constraint. Simulation results show that runtime of the proposed scaling algorithm is 34% and 50% smaller than those of the binary search algorithm and greedy algorithm, respectively.

알루미늄과 그 합금은 내부식성(corrosion resistance)이 좋고, 밀도가 낮아 높은 연료소비 효율을 필요로 하는 항공기와 자동차 같은 운송수단의 내-외장 소재로 사용되고 있다. 또한 알루미늄의 높은 내부식성을 이용하여 철강소재의 부식을 방지하는 보호막으로도 폭 넓게 사용된다. 물리기상증착(physical vapor deposition)으로 알루미늄을 코팅하면 박막 성장 초기단계에서 핵(nucleus)을 형성하고, 형성된 핵을 중심으로 주상 구조(columnar structure)로 박막이 성장하는 것이 일반적으로 알려진 방식이다. 주상 구조의 알루미늄 박막은 주상정과 주상정 사이에 필연적으로 공극(pore)이 존재하게 되어 부식을 일으키는 물질이 박막으로 침투하게 되고, 부식 물질과 모재가 반응하여 공식(pitting corrosion)이 발생한다. 본 연구에서는 스퍼터링(magnetron sputtering)을 이용하여 치밀한 조직을 갖는 알루미늄 박막을 코팅할 수 있는 공정을 개발하고, 치밀한 알루미늄 조직이 내부식성에 어떠한 영향을 미치는지 평가하였다. 기판은 냉연강판(cold rolled steel sheet)이 사용되었으며, 알루미늄 타겟의 순도는 99.999%, 크기는 직경 4"이었다. 냉연강판은 진공용기(vacuum chamber)에 장착하기 전에 계면활성제를 이용하여 표면에 존재하는 기름성분을 제거하였으며, 진공용기에 장착한 후에는 아르곤 가스를 이용하여 발생시킨 글로우 방전으로 표면에 존재하는 산화물을 제거하였다. 알루미늄 박막의 조직에 영향을 미치는 공정변수를 확인하기 위해서 스퍼터링 파워, 공정 온도, 공정 압력, 외부 자기장 세기 등의 공정 조건을 변화시켜 코팅을 실시하였다. 실험을 통해서 얻어진 최적 조건으로 알루미늄을 코팅할 경우, 알루미늄 bulk의 밀도와 비교하여 약 94.7%의 밀도를 갖는 알루미늄 박막을 코팅할 수 있었다. 알루미늄 박막이 약 3 ${\mu}$m의 두께로 코팅된 냉연강판의 내부식성 평가(salt spray test, 5% NaCl) 결과, 평가를 시작한 후 72시간 후에도 적청이 발생하지 않았다.

This study aims to explore how the individual characteristics of the senior job placement project coordinators and the organizational structure in which they work affect their job performance. A survey of 251 coordinators who were working in the senior job placement project agencies were retrieved and used for empirical analysis using the SPSS Win.12 program. The result shows that a sense of self efficacy, the individual traits(understanding of the senior job placement project, attitude towards the elderly) and the organizational structure(the level of formalization of agency) were statistically significant predictors of the level of job performance. The results of this study show that the coordinators who were more confident about themselves, who had more understanding about the senior job placement project, who had more positive attitude towards the social activities of the elderly, and who were working in agencies with higher level of formalization had a higher level of job performance than their counterparts. Therefore, more policy and program considerations should be taken into account in empowering the coordinators, and in providing them with standardized organizational process. This in turn will ultimately enable them to better serve the elderly who participate in the senior job placement projects.
