For this study, a sample of 775 self-sufficiency program participating workers completed depression questionnaire, optimism scale and willingness for self-sufficiency scale. The data was analyzed using the Baron & Kenny's moderating effect verification method. The results of the analysis showed that depression had a significant negative effect on willingness for self-sufficiency, and optimism had a significant positive effect on willingness for self-sufficiency. The results verified the moderating effects of optimism on the relationship between depression and willingness for self-sufficiency. On the basis of the results, We discussed that optimism can reduce the negative effect of depression on willingness for self-sufficiency and improve willingness for self-sufficiency.

낙관적 기법은 실시간 데이터베이스 시스템을 위한 동시성 제어로서 적합하다. 특히, 종료시 한을 초과한 트랜잭션이 시스템으로부터 제거되는 펌 실시간 데이터베이스 시스템에서 낙관 적 기법은 잠금 기법보다 우수한 성능을 보인다. 그러나 낙관적 기법은 낭비적 수행과 과도 한 재시작의 문제를 안고 있다. 종료에 가까운 트랜잭션의 재시작은 시스템 자원의 낭비는 물론 종료시한 초과 가능성을 높인다. 발생되는 재시작의 수를 줄이기 위해서 충돌하는 트 랜잭션들간의 직렬화 순서를 동적으로 저장하는 방법이 이용되었다. 그러나 직렬화 순서의 동적 조정 기법을 이용함에도 불구하고 불필요한 재시작이 발생된다. 본 논문에서는 기존의 타임스탬프 기반 동시성 제어에서 이용되던 Thomas 기록 규칙을 이용하여 이러한 불필요 한 재시작을 제거한 개선된 실시간 낙관적 동시성 제어 기법을 제한한다. 제안된 방법은 요 구되는 데이터베이스 일관성을 보장하면서도 발생되는 재시작 수를 줄임으로써 성능을 향상 시킨다.

The purpose of this study was to investigate the degree of optimism, academic resilience, and major satisfaction of nursing students, and identify influencing factors of major satisfaction. The study was a cross-sectional descriptive correlational design. A convenience sample of 286 nursing students was conducted from a university in Busan. Data were analyzed through descriptive statistics, t-test, one way ANOVA, Pearson's correlation coefficient, and hierachical multiple regression analysis using IBM SPSS version 23.0. The average score of optimism, academic resilience and major satisfaction in nursing students were 3.85±0.54, 3.87±0.52 and 3.75±0.63 respectively. The degree of major satisfaction was positively correlated with optimism and academic resilience. The significant predictors of major satisfaction were optimism(β=.385, p<.001) and academic resilience(β=.356, p<.001), explaining 49.2% of the independent variables. Accordingly, in order to increase the major satisfaction level of nursing college students, it is necessary to develop a program that can improve optimism and academic resilience, and apply it in the nursing curriculum.

The subjects were 3 and 4 grade students who had clinical practice experience among 3 nursing students at G university, and 362 questionnaires were used as research data. The data analysis used regression analysis, SPSS macro and bootstrapping methods to examine the mediating effects of optimism on college students' stress and happiness. The results showed that stress, happiness, and optimism were significantly correlated, and stress had a direct effect on college students' happiness. In other words, the higher the level of stress, the lower the happiness index of college students. The optimism was partially mediated between stress and college students' happiness index. Therefore, in order to increase the happiness index of college students, it is necessary to develop and implement a program for happiness enhancement as one of the program strategies that can enhance stress.

Seligman argues that an optimistic athlete wins based on a study of US professional baseball and professional basketball players.(trans. Choi, 2008). So, the purpose of this study was to investigate whether optimism can predict the performance of badminton youth representatives. 60 high school students were divided into two groups according to their performance. We used the revised Life Orientation Test (LOT-R) developed by Scheier, Carver and Bridges(1994) and translated into Korean version by Shin Hyun-sook(2005). For this study, the data were analyzed by frequency analysis, reliability analysis, and independent t - test. As a result, there was a statistically significant higher level of optimism in the excellent group than in the non-excellent group. So, in order to improve sports performance, we need psychological skills training that can improve optimism as well as physical training and skills training.
