In this paper, we propose the moderating effects of self-efficacy and social support on the relationship between physical therapists' job stress and psychological burnout. Based on the previous studies, this study set up three types of variables: 1) independent variable, 2) moderating variable, 3) dependent variable. Job stress was identified as an independent variable, self-efficacy and social support was identified as a moderating variable and psychological burnout was identified as a dependent variable. To empirically conduct this study, a total of 200 questionnaires were distributed to physical therapists. Consequently, a total of 155 survey responses were collected. The survey results are as follows. First, the result showed a high-level of correlation among job stress, psychological burnout, self-efficacy, and social support. Second, self-efficacy was found to have a moderating effect on the relationship between the physical therapists' job stress and psychological burnout. Third, social support was found to have a moderating effect on the relationship between the art therapists' job stress and psychological burnout.

웹 로그 기반의 웹 사용 마이닝은 명시적 평가 의존, 확장성 결여, 그리고 다차원 및 희박한 데이터에 성능이 떨어지는 협력적 여과의 문제를 다소 해결할 수 있다. 그러나 k-Means 군집화 방법으로 생성된 군집속 유사 사용자 이동 패턴으로는 클러스터속 사용자 전체의 선호도를 표현할 수 없으므로 사용자 이동 패턴인 트랜잭션들로부터 사용 프로파일을 유도해야 한다. 본 논문에서는 유사 군집 사용자들의 관심과 기호를 표현할 수 있도록 클러스터 내부 데이타로부터 평균 가중치 및 빈발 지지도 임계값을 사용하여 개선된 사용 프로파일을 생성하고 실험 데이터를 통한 예측력과 추천에 대한 성능을 평가한다.

Recently, due to technical developments of various storage devices and networks, the amount of data increases rapidly. The large volume of data streams poses unique space and time constraints on the data mining process. The continuous characteristic of streaming data necessitates the use of algorithms that require only one scan over the stream for knowledge discovery. Most of the researches based on the support are concerned with the frequent itemsets, but ignore the infrequent itemsets even if it is crucial. In this paper, we propose an efficient method WSFI-Mine(Weighted Support Frequent Itemsets Mine) to mine all frequent itemsets by one scan from the data stream. This method can discover the closed frequent itemsets using DCT(Data Stream Closed Pattern Tree). We compare the performance of our algorithm with DSM-FI and THUI-Mine, under different minimum supports. As results show that WSFI-Mine not only run significant faster, but also consume less memory.

This study was examined relation to comprehensive needs and the quality of life in cancer patient. The Study period was 15 to 24 October 2012. The participants were 100 cancer patients more than 20 years old with cancer. Information and educational requirements are the highest need, and social support is the lowest one in patients with cancer. The longer survival time after diagnosis of cancer was, the higher social support requirements were needed. The Information and education requirement about healthy life showed higher in a family history of cancer. The cancer patients with stage IV ask higher service requirement significantly. and showed that physical and psychological requirements were getting higher, the quality of life became lower. As a result of this study, Physical and Psychological requirements were the most significant factors that affect the quality of life in cancer patients. Therefore, it is necessary to develop the physical and psychological supporting system and to provide appropriate Intervention for them.

This study The purpose of this study is to analyze the structural relationship among social support, job satisfaction, happiness, teacher efficacy. Participants were 249 teachers from teachers' training programs. Descriptive statistics analysis and path analysis were conducted. SPSS 22.0 and AMOS 21.0 were used. As a result of the analysis, it was found that teachers' social support had a significant effect on job satisfaction and happiness, and job satisfaction had a significant effect on happiness and teacher efficacy, but social support and happiness did not directly affect teacher efficacy. However, it was found that social support has a partial mediating effect through a sense of happiness through job satisfaction, and social support has a complete mediation effect through a sense of teacher efficacy through job satisfaction. This study is considered to be the basic data for preparing a plan to improve the teacher's sense of efficacy, an important factor in determining the quality of public education.

This study analyzed the relationship between the social support and life satisfaction of the new-middle aged job seekers, and the mediating effect of re-employment desire. Firstly, the relationship between social support and life satisfaction were significant, therefore it confirmed social support should be expanded to improve new-middle aged life satisfaction. Secondly, the desire for social status, self-realization and leisure utilization were significantly influenced in the relationship between the desire for re-employment and life satisfaction. Thirdly, the re-employment desire had a partial mediating effect in the relationship between social support and life satisfaction. These results suggest that it is important to establish a social network for emotional support continuously after retirement, in addition to career planning for re-employment in the process of preparing for retirement, in order to increase the level of life satisfaction of the new-middle age.

Sequential pattern mining finds all of the frequent sequences satisfying a minimum support threshold in a large database. However, when mining long frequent sequences, or when using very low support thresholds, the performance of currently reported algorithms often degrades dramatically. In this paper, we propose a novel sequential pattern algorithm using only closed frequent sequences which are small subset of very large frequent sequences. Our algorithm generates the candidate sequences by depth-first search strategy in order to effectively prune. using bitmap representation of underlying databases, we can effectively calculate supports in terms of bit operations and prune sequences in much less time. Performance study shows that our algorithm outperforms the previous algorithms.

This study intended to examine the correlation of career self-regulation (plan and check-up, positive thinking, career feedback, environment formation for career) and career identity (career decision, indecisiveness, career indecision) caused by parental career support (informative, emotional, financial, and empirical) among freshmen, sophomores, and juniors in the radiotechnology department. For assessment, a survey was conducted and according to the results, there existed correlation as follows. Regarding parental career support, emotional support is plan and check-up (r=.25, p<.001), Career feedback (r=.54, p<.001), and positive thinking (r=.46, p<.001) showed high positive correlation while informative support showed correlation in all factors showing high correlation with environment formation for career (r=.22, p<.001), plan and check-up (r=.20, p<.001), career feedback (r=.24, p<.001), and positive thinking (r=.26, p<.001). Financial support career feedback (r=.33, p<.001) and positive thinking (r=.34, p<.001) showed somewhat higher correlation. All factors of environment formation for career (r=.18, p<.001), plan and check-up (r=.25, p<.001), career feedback (r=.37, p<.001), and positive thinking (r=.30, p<.001) showed high correlation. Informative support showed high correlation only with career decision (r=.27, p<.001) and financial support also showed high correlation only with career decision (r=.18, p<.001). Also, empirical support was somewhat highly correlated only with career decision (r=.23, p<.001). Regarding school-year difference depending on parental career support, there was significant difference between emotional support (F=8.52, p<.001), financial support (F=8.97, p<.001), and empirical support (F=5.36, p<.05) while informative support was dismissed. Regarding school-year difference depending on career self-regulation, there was significant difference between career feedback (F=8.48, p<.001) and positive thinking (F=16.29, p<.001) while environment formation for career and plan and check-up were dismissed. Regarding school-year difference depending on career identity, there was significant difference between career indecision (F=4.01, p<.05) and career decision (F=11.72, p<.001) while indecisiveness was dismissed. According to the analysis results, parents' active support to their child like respecting and listening to their opinion on career, provision of career related experience or information, and provision of necessary financial aid for their study or academic preparation made the students plan and exploring their career, examine accomplishment progress, have positive idea to realize their objectives. In addition, the students were able to establish the objective of their career by forming the environment that helped them realize their objectives by seeking advices and encouragement from surroundings. Meanwhile, the parents' attitude to respect and listen to their child's career related opinion affected their career decision and indecision. Although informative support helped the students' career decision, financial and empirical support caused effect only to career decision.
