본 연구의 목적은 청소년기업가지수를 활용하여 청소년기업가정신교육이 청소년에게 어떠한 영역에서 효과가 있는지 JA Korea-삼성 청소년기업가정신교육을 중심으로 검증해 보는 데 있다. JA Korea-삼성 청소년기업가정신교육 프로그램에 참여한 고등학생 124명을 대상으로 청소년기업가정신지수의 3개 영역(인지, 사회, 정의), 9개 하위요소(혁신성, 적극적 문제해결, 대인관계, 리더십, 공감, 위험감수성, 진취성, 자기효능감, 모호함에 대한 인내)를 교육 사전-사후로 나누어 대응분석을 실시하였다. 주요 분석결과는 다음과 같다. 첫째, JA Korea-삼성 청소년기업가정신교육에 참가한 고등학생의 청소년기업가정신지수를 사전-사후 대응분석을 실시한 결과 통계적으로 유의미하게 상승하였다. 둘째, 청소년기업가정신지수를 구성하는 인지, 사회, 정의영역 중인지영역과 정의영역에서 유의미하게 상승하였다. 마지막으로 9개 하위요소에 대해 분석한 결과 대인관계 및 위험감수성 요소를 제외하고 7개 하위요소에서 통계적으로 유의미하게 높아졌다. 본 연구는 청소년기업가정신지수를 활용하여 교육의 효과성을 검증하고 청소년기업가정신교육의 바람직한 방향성을 수립하는데 필요한 객관적인 자료로 활용 가능할 것으로 기대된다.

In this paper, when the observations are distributed as inverse gaussian, we developed the noninformative priors for ratio of the parameters of inverse gaussian distribution. We developed the first order matching prior and proved that the second order matching prior does not exist. It turns out that one-at-a-time reference prior satisfies a first order matching criterion. Some simulation study is performed.

The performance testing system of temporary construction equipment and materials are a previous inspect institution to produce only goods beyond the limited-performance, be certificated through a previous test, the purpose of which is to prevent an illegal goods from spreading abroad. The formal certification not only pass the test in an ordinary means but also isn't the term of validity on a certificated goods. Because of the above two reasons, an accident doesn't reduce, and a illegal goods become to be circulated. So, in this study, we analysis the problem of the follow-up service based on the formal certification and we suggest the improvement through comparative study on the follow-up of domestic and foreign.

The aim of this study was to analyze the effectiveness of a crisis intervention program for the unemployed. The intervention included understanding one's experiences of unemployment and new dynamics of one's family, improving family relations, decreasing depressed mood through cognitive restructuring, assertiveness training, and job skill acquisition. Ss were 14 recently unemployed adults from Seoul area. A pretest and a posttest were administered. The effect of the program have been analyzed in terms of assertiveness, family relations, and depressed mood. The intervention yielded a statistically significant change in assertiveness for the unemployed who live with their families. The homeless unemployed have shown a statistically significant change in family relations. Qualitative analyses on the group processes also have been conducted. Implications for the future practice are discussed.

A model of cooperative learning, Pair Programming was applied to regular class for middle school students. Algorithm and programming skill were taught through the pair programming for two week and the achievement was analyzed based on 4Cs(Critical thinking, Communication, Collaboration, Creativity) proposed by the NEA(National Education Association). The control group was statistically significant on Critical Thinking between pre-test and post-test1, while the experimental group was statistically significant on all measurements of 4Cs. Between pre-test and post-test2, the control group showed overall little difference in range of 0.2 points on the 4Cs average scores. while the experimental group was statistically significant on all measurements of 4Cs. Between post-test1 and post-test2, there was no significant difference on 4Cs average scores in both groups. The experimental group showed higher score results on all 4Cs than the control group. This study verifies that the benefits of Pair Programming on 4Cs.

IR(Investor Relation) is an active management activity to provide well balanced information to investors which can reduce asymmetry of information between investors and management. This activity could contribute to the long-term development of corporation with increased mutual trust between investors and management. Consequently, in these days, ill is widely recognized as an effective measure of securing corporate transparency, maximization corporate value, and stock-holder oriented management. The purpose of this study is to examine the effect of corporate IR activity on investment behavior as well as stock price. It is assumed that if asymmetry of information between investors and management is cured by active ill activity from a corporation, with more transparent and reliable information of the firm at hand investors would more actively involved in trading. Statistically speaking, I assumed that the more information provided by ill activities, the higher value of a corporation at the stock trading.

The purpose of this study was to examine the effect that preferred music listening had on police officers' occupational stress and fatigue. The musical intervention took place over a total of six sessions from October 11 to October 19, 2016. At each session, the experimental group (n = 19) received 20 minutes of music listening with individually customized playlists that were compiled based on their preferred music list. The control group (n = 21) simply took a break from work for 20 minutes. Every participant checked his or her occupational stress and fatigue level before and after the experiment using the Occupational Stress Inventory and Subjective Symptoms of Fatigue Test. The data were then analyzed by the SPSS 22.0 statistics program. To examine the homogeneity and pretest-posttest results between groups, an independent t test was conducted, and a paired t test was used to examine the pretest-posttest results within groups. The results confirmed all hypotheses. Findings support that the use of preferred music listening is an effective way to help police officers to control their occupational stress and fatigue. This study used a convenience sample and has limited generalizability. Future research should explore interactive approaches in music therapy as well as receptive music listening for alleviating police officers' occupational stress and fatigue.

Objective : The purpose was the effect of sensory integration therapy combined with an eye tracker on the sensory processing and visual perception of children with developmental disabilities. Methods : It was a single-subject study with a multiple baseline design between subjects, and the intervention applied sensory integration therapy combined with an eye tracker. Visual-motor speed and saccadic eye movements were assessed at each session of baseline and intervention periods. As pre- and post-evaluation, sensory profile, Korean-Developmental Test of Visual Perception and Trail Making Test were conducted. The results of each session evaluation and pre- and post-evaluation researched the effectiveness of the intervention through visual analysis and trend line analysis. Results : As a result of the evaluation for each session, the slope of the trend line for all children in visual-motor speed and saccadic eye movement increased sharply during the intervention compared to the baseline. As a result of the pre- and post-evaluation, the sensory processing of movement, body position, and visual changed from more than that of peers to a level similar to that of peers. In visual perception, all children's ability of Visual Closure increased. As a result of Trail Making Test conducted to confirm the improvement of children's visual tracking and visual-motor abilities, all children showed a decrease in performance time after the test compared to before. Conclusion : It was confirmed that sensory integration therapy combined with an eye tracker for developmental disabilities has effect on sensory processing and visual perception. It is expected to play an important role clinically as it can stimulate children's interest and motivation in line with recent technological improvements and the spread of smart devices.
