Objective : The purpose of this study was to develop an assessment tool to measure Korean occupational balance. Methods : From March 2017 to July 2019, preliminary questionnaire was prepared through analysis of previous research and expert focus meeting, and preliminary questions were selected through the Delphi survey. In order to verify the validity of the items, Rash analysis was conducted to analyze the persons and items fitness, the distribution of item difficulty, separation reliability, and the appropriateness of the rating scale. Results : Among 141 subjects, 9 (6.38%) in time use and 11 (7.80%) in the occupation area were inappropriate subjects. As a result of analyzing the appropriateness of the items except for the inappropriate subjects, the 3 items were judged as ineligible items, but 1 item of the occupation characteristics was finally deleted based on the theoretical and clinical grounds. In the analysis of the scale, 4 points were more appropriate than the 5 point scale, and the separation reliability was .86~.94. Finally, 3 categories (time use, occupation area, occupation characteristics) and 18 items were selected. Conclusion : The occupational balance assessment tool was selected three categories and 18 questions finally, three categories and 18 questions, and was developed on a four-point Likert scale. Further research needs to prove the concurrent validity of the K-OBA and to analyze the factors that influence the occupational balance.

The purpose of this study was to investigate self-esteem item goodness-of-fit in sports talented children with socio-psychological aspect, which may be a basis of developing global sports leaders. Fifty children who were selected by 2010 sports talent identification program at Korea National Sport University participated in this study. All participants were asked to answer the questionnaire using Rogenberg (1965) self-esteem scale. Total 8 questions were used with 4 point Likert scale and high point stands for higher self-esteem status. Reliability of Cronbach's ${\alpha}$ was.785 in this study. Frequency analysis, descriptive statistics, and reliability analysis were conducted with SPSS 18.0. WINSTEPS 3.70 (Linacre, 2010) was used for calculating item goodness-of-fit and subject reliability, scale propriety, item goodness-of-fit and item level of difficulty, and level of difficulty were calculated. Statistical analysis showed results as follows. First, it was reported to be suitable for subject reliability in self-esteem as 1.01~1.03 and item reliability as 1.01~1.01. Second, 4 scale was suitable for scale propriety resulting from stage index judgment. Third, 2,7,8 and 3 question showed problems in item goodness-of-fit and item level of difficulty. Finally, scale propriety was reported to be inappropriate for considering sports talented children's ability distribution and scale level of difficulty.

The purpose of this study was to examine how parental stress coming from breeding children with disabilities affected their leisure constraints. The participants of this study were parents with mentally retarded children who were involved in physical activities in 6 places; 4 special schools for the children in Seoul and Kyunggi province, a physical education class in a university, a physical education class with a university and a private physical education class. We surveyed the parents selected through purposive sampling and data from total 355 participants involved in the survey were analysed. For this, frequency analysis, exploratory factor analysis, reliability analysis, one-way ANOVA and multiple regression analysis were used. The outcome of this study showed that there was not meaningful difference in breeding stress depending on the types of the disabilities. However the result presented meaningful difference in stress from children adaptation according to the degree of the disabilities. Moreover, the difference were found in some factors such as children's sex and family income. As a result, the finding indicated that parental stress had an effect on the limitation of parents' leisure ability.

Mathematical curriculum has been developed based on learners' level and difficulties of contents. Succeed in solving problem in mathematics depends on the completion of the precedent learning. Thus, it is important to diagnose students beforehand. It is also important to develop problem-solving skills for students. In this thesis, Q&A system is proposed to help students learn various problem solving skills in mathematics. Although the system is currently applicable to mathematics, it can be applied to any other subjects.

In this study I divided the development history of educational serious games into three periods. from 1995 to 2020 in Korea. I drew out some characteristics of each period. And I analyzed the correlation between the level of technology and learning effects or fun. so I found out some results. According to my analysis, the level of technology and learning effects and fun are not related to successful factors. While play style which is familiar and accessible to students like casual game has been commercially successful. It also confirmed that well-balanced games between fun and learning effects are a key factor in commercial success.

According to the 2007 Korea library yearbook, 162 out of 589 special libraries are one person libraries which means an individual librarian takes responsibilities of all librarian tasks. Due to its particularity and diversity, however, there is lack of research on special libraries compared to the other libraries and no job analysis for human resources to be effectively managed has been done. This study aims to understand the current status of one person library by investigating its tasks and frequency, importance, difficulty of its duties. This study also suggests plans to improve the job by analyzing its association with affiliated organizations of one person library.

반도체의 device design rule이 shrink 됨에 따라 공정이 난이도가 높아지고 이에 따른 관리가 어려워지고 있다. 특히 미세 particle에 대한 제어의 필요성은 보다 커졌다. 진공 chamber 발생하는 미세 particle의 주요 원인으로는 공정 중 발생한 polymer, chamber 내 부품의 식각 및 스퍼터링에 의한 부산물 등이 있다. Plasma 공정 도중 발생한 particle은 plasma 내 전자에 의해 대전되어 음의 전하량을 가지게 된다. 음의 전하량을 가진 particle은 plasma와 wafer의 경계면에서 형성되는 sheath 때문에 wafer에 도달하지 못하고 plasma 내에 부유하게 된다. 이러한 particle은 plasma가 꺼지게 되면 sheath가 사라지면서 wafer에 도달하게 되고 wafer의 오염을 유발하게 되고 생산 수율을 저하시키는 요인이 된다. 이러한 이유로 최근 plasma 공정에서는 공정 중 발생하는 부유성 particle에 대한 관리가 중요해졌다. 이를 관리하기 위해 plasma를 끄기 전 부유성 particle을 제거하는 방안을 고안하고 평가를 진행하였다. 공정이 끝나고 plasma가 꺼지기 전 plasma를 유지하여 부유성 particle이 wafer에 도달하지 못하는 상태에서 gas purge를 실시한다. 이러한 과정 후 plasma를 끄게 되면 부유성 particle이 wafer에 도달하는 것을 감소시키게 된다. 이번 평가를 통해 부유성 particle에 대해서 대략 20%의 감소 효과를 볼 수 있었다. 이를 토대로 향후 조건 최적화 후 적용 시 particle 감소뿐 만 아니라 수율 향상에도 기여할 수 있을 것이라 기대된다.
