The purpose of this study was to examine the effectiveness of drama education program for elementary school students by using method of meta-analysis. For the purpose of the study, master's theses, doctoral dissertations, and journal articles published in Korea up to July, 2013 were systematically reviewed. As a result, a total of 19 studies were eligible for the inclusion criteria. The mean effect sizes and test for homogeneity of effect size(Q-statistic) were analyzed by using Comprehensive Meta-Analysis software 2.0. The main findings of the study were as follows. First, the average effect sizes for drama education program were ES=1.103 of self-expression, ES=1.011 of self-esteem, ES= .858 of creativity and ES= .672 of sociality. Second, by analysing the moderate variables of the effect size for drama education program, 'sessions' were statistically significant. Based on the study results, the research and practice implications were discussed.

In this Paper, We Empirically Investigated what kind of Risks Exist that Drive high Failure rate of cloud Services, and whether Perception of such risks leads to the Adoption of the Abandonment Option of cloud Services. Such risk Perception is the Individual-level Factor, and we Empirically Tested whether Organizational Contexts such as CEO's Innovativeness and Dandwagon Effect can Moderate the Positive Effects of such Individual-level Risk Perception on the Adoption of Abandonment option. We Collected Survey data from IT Professionals Working for the Small and Medium-sized Companies near Seoul and found that the Perceived Technical Risk and Economic Risk Influence the Adoption of Abandonment Option. Out of two Organizational Contexts, only CEO's Innovativeness Moderates the Positive Influence of Technical Risk on the Adoption of Abandonment Option. Organizational Factors Demonstrated very Limited Moderation Effect on the Influence of Individual-level Perception of Cloud Service Risk on the Adoption of Abandonment Option.

The purpose of this study is to investigate the effects of informational diversity-sensitive orientation on employee attitudes, focusing on the moderating effects of communication. Recently, diversity within organizations has intensified and the importance of diversity management within organizations is increasing. Diversity studies have focused on the variance of objective diversity characteristics, and have provided mixed results. In order to overcome limitations in the research, this study focuses on members' perception of diversity. To this end, the variable of informational diversity-sensitive orientation(IDSO) was used. Sample data is derived from 301 surveys of employees in firms located in South Korea. Results show that informational diversity-sensitive orientation(IDSO) had a positive effect on job satisfaction and organizational commitment. Regarding the moderating effect of communication, a positive moderating effect was exhibited only in co-worker communication, and differential influence derived from communication type. Based on the analysis results, we discuss research implications and directions for future research.

This study explored the relationship between the Resilience and Organizational commitment, The police officers' perception on the resilience has been measured, and then how their perception on the resilience affects the organizational commitment has been examined. This study aimed at measuring the effects of police officers' perception on the resilience on organizational commitment By reviewing previous finding, police officers' resilience(Self-Regulation Skills(Regulation skills, Cause Analysis skills, Impulse control skills), Interpersonal Skills(Expansion skills, Communication skills, Empathy skills), Positive Capacity(Appreciate, Life satisfaction, Self-optimism)) were selected as independent variables, Organization Commitment(Affective commitment, Continuance commitment, Normative commitment) was selected as dependent variable. The result of analysis showed that Life satisfaction>Cause Analysis skills>Communication skills> Empathy skills> Appreciate> Impulse control skills influenced in Affective commitment (positive), Life satisfaction>Self-optimism>Regulation skills>Communication skills>Cause Analysis skills in Continuance commitment(positive), and Expansion skills>Empathy skills>Self-optimism>Life satisfaction>Impulse control skills in Normative commitment (positive).

수 MeV~수십 MeV 양성자빔을 이용해 백금, 은 등의 나노입자 제조실험을 수행하였다. 나노 입자는 의료분야와 산업 분야에서 그 응용성이 다양해 여러 지 방법을 이용한 제조기술이 개발되고 있다. 전자빔, 감마선, 양성자빔 등의 방사선을 이용한 나노입자 제조방법은 가장 널리 이용되고 있는 화학적 제조방법에 비해 비교적 공정이 단순하다는 장점을 가지고 있지만 공정 변수의 제어방법이 확립되어 있지 않아 이에 대한 연구가 필요한 실정이다. 특히, 양성자빔의 경우 에너지에 따른 투과깊이의 조절과 플럭스나 총 선량, LET (Linear Energy Transfer) 등의 변수와 제조된 나노입자의 상관관계 등에 대한 연구가 선행되어야 한다. 본 논문에서는 백금산 용액을 이용한 나노입자 제조 결과와 대면적 양성자빔을 이용하기 위한 초음파 이용 나노입자제조장치의 제작 및 실험결과에 대해 논하고 향후 건설될 100MeV 선형 양성자가속장치의 나노입자 제조실험에의 응용을 위한 이용시설을 소개하고자 한다. 나노입자 제조실험은 한국원자력의학원의 MC-50 싸이클로트론을 이용하여 수행하였으며, 가속기로부터 인출되는 에너지는 35, 45MeV, 빔전류는 수십 nA~수${\mu}A$의 범위 내에서 조절하였다. 제조된 나노입자는 TEM을 이용하여 그 크기와 분포를 관찰하였다. 대면적의 양성자빔을 이용하는 경우, 수mm의 두께와 수십 cm의 직경을 가지는 원반 모양의 시료용기를 사용하여 양성자빔의 에너지와 선량을 정확히 조절할 수 있게 되는데 이 때 용기 내 시료와 양성자빔간의 균일한 반응을 위해 용액을 적절하게 섞어 주어야만 한다. 이러한 목적으로 초음파를 이용하여 나노입자 제조장치를 제작하여 실험을 수행하였다. 나노입자 제조는 현재 교과부의 지원으로 경주 건천지역에 건설되고 있는 100MeV 선형양성자가속기의 주요 이용 분야 중의 하나로 20MeV 빔라인 중 한 개의 빔라인과 표적실을 나노입자 제조 등의 실험을 위한 시설로 구축 중이다. 최대 평균전류 1.6mA 까지 가능하고 펄스폭은 0.05~1.33 msec까지 조절가능하도록 개발되고 있다.

The purpose of this study is to verify effects between the place attachment and the place value in public libraries; and also to identify whether frequency and purpose of usage, length of residence, and website use play a moderating role in the influential relationship between users' place attachment and the perception of place value for public libraries. Users' place dependence affected the library's value positively(+) due to moderating effect of usage frequency of the library and the users' length of residence. In order to estimate the moderating effect by purpose of use, the groups were divided by purpose of library use and the relationship between place attachment and place value by groups were analyzed. However, website usage bore no effect on users' place attachment or perception of place value to their local library. This study showed that place attachment as an affective indicator on users is very useful variable to explain the value of libraries as a social and cultural place.

The aim of this study is to find the factors affecting attitude on u-health system using Pender's Health Promotion Model (HPM) and also, analyze the moderating effect of gender variable in research model. To assess the proposed research model based on HPM, this study adopted Partial Least Square (PLS) method using Smartpls 2.0 version for the evaluation of research model. Thus, this study used survey questionnaire in order to collect useful data to potential users of u-health system. As a result of analysis, the examined variables explain 29% of variance on attitude to use of the u-health system. According to the PLS analysis, self efficacy and perceived benefits showed significantly positive relationship on attitude to use of u-health system. In addition, on the moderating effect of gender variable, female had more interest on self efficacy for positive attitude on use of u-health system.

The concept of attachment between users and Information Systems; specifically on mobile devices was examined in this study. Furthermore, the moderating effect of users' past experience also was investigated. The empirical study was done involving 240 university students; to investigate the participants' perceived value, perceived enjoyment, attachment and also continuous usage of mobile devices. Additionally, participants' past experience was also enquired to examine its moderating effects. The results show that attachment is mediating both perceived value and perceived enjoyment with continuous usage. Meanwhile, past experience negatively moderates perceived enjoyment with attachment and also negatively moderates attachment with continuous usage.
