Perceptions of organizational politics(POPs) have stress-based effect as job demand and lead to employee's negative attitudes and behaviors. According to job demand resource model, burnout develops when high job demand deplete employee's resources, which lead employees to low levels of motivation and high levels of cynicism and frustration. Currently, in studying the relationship between POPs and burnout there is a lack of researches on certain settings and conditions. The present study examined a model in which relationship between POPs and burnout was mediated by psychological need satisfaction. And also, this study tested moderating role of psychological capital between POPs and need satisfaction. A total of 220 employees in telco and electronic manufacturing company in South Korea participated in this study. The result of this study showed that need satisfaction works as mediating variable between POPs and burnout and psychological capital had moderating effect between POPs and need satisfaction. This study proposes a new framework of POPs by examining linking mechanism of need satisfaction and psychological capital. The results of this study provide practical insight to HR practitioners and business leaders.

The objective of this study is to find out whether policy acceptance(attitude formation and intention of action) is affected by the message appeals(rational vs. emotional) when policy PR messages emphasize prosociality, and by various factors such as trust in government, involvement, and demographic factors as moderating variables. Although message appeals does not show any difference by itself, interaction effect is observed between trust in government and message appeals; the rational appeal is more effective to those with low trust in government while the emotional appeal is more effective to those with high trust. No other interaction effect is founded but involvement, gender, and age group show important main effect in policy acceptance; high-involvement group and female group are more favorable in attitude toward prosocial policy and behavior intention compare to the each of counterparts, whereas older group is more favorable in behavior intention.

This paper presents a study investigating the effects of VR learning style on user attention and memory. The study involved users performed the guided or unguided style learning in the virtual environment while user attention was measured through physiological sensors (EEG, ECG, and GSR) and an eye tracking system. The users experienced the five specific events in a virtual environment associated with different stimuli, while they were given more specific goals during the guided task whereas they were given more goal asking them to actively search for the interesting items during the unguided task. The subject's attentions workload, feelings, memories about VR experience were measured by using a variety of physiological sensors during the task, video analysis, and post test survey. The results showed that the unguided task followed by the guided task made a considerable learning effect by giving a preview effect to the user. Moreover, the guided task drew more user attention and mental workload than the unguided task did.

This study investigated the effects of job demand-resource variables that appear in a special organizational environment such as a hospital on job burnout and job engagement using the job demands-resources model of Schaufeli & Bakker(2004). And also the study investigated to verify discriminatory mediating roles of emotional labor strategies in the process. The main finding of this study was as follows: Job demands-resources showed a positive relationship in the job burnout and job engagement, and job demands induced surface acting and job resources induced deep acting. However, deep acting showed a positive relationship to job engagement, and surface acting showed a negative relationship with job burnout unlike in previous study results, which was not significant. The results of verifying the meditation model through Boostrap showed that since the two indirect effects were not significant, the meditating role of emotional labor strategies was not verified in the effects of job demand-resource levels on job attitudes, including job burn out and job engagement.

학습자들이 미래 사회에 능동적으로 대처하기 위해서는 기존의 지식을 축적, 활용하는 것뿐만 아니라, 새로운 행동 양식을 개발하고 환경의 변화에 적절히 대응해 나갈 수 있는 능동적인 자세와 상응하는 창의적인 힘을 키우기 위해 '창의성 신장'이 강조되고 있다. 선행연구에 따르면 교사의 발문이 학생의 수학 학업성취도, 수학적 사고력향상, 수학에 대한 관심과 흥미에 긍정적인 영향을 주고 있음을 시사하고 있지만, 수학교육에서 창의성 신장을 위한 교사의 발문에 관련한 구체적인 연구는 미흡한 실정이다. 따라서 2007 개정 교육과정에서 강조하는 수학적 의사소통능력과 창의성, 수학적 사고력 신장에 기여하고 학생들의 수학과 학업성취도 뿐만 아니라 정의적 영역(흥미, 태도, 호기심 등)의 향상을 도모할 수 있는 교사 발문의 특성 연구가 필요하다. 본 연구는 도형영역 수업에서 교사의 발문 특성을 분석하고, 수업에서 사용되는 자료와 수업에서 학생들의 수학적 창의성 신장을 효과적으로 도울 수 있는 교사 발문의 특성을 연구하는 것을 목적으로 하였다. 본 연구를 위하여 우리나라 2007개정 교육과정 수학과 4학년 1학기 도형 영역 관련 단원인 삼각형을 주제로 교과서에서 제시한 발문 내용을 분석하고, 실제 교수-학습 과정에서의 교사 발문의 실태를 알아보고자 제주교육인터넷방송국에 탑재되어 있는 7차 교육과정 4학년 1학기, 2학기 도형 관련 3개의 수업을 관찰 및 분석하였다. 이를 통해 수학적 창의성 신장을 위한 교사 발문의 특성을 수학적 창의성의 하위요소별로 나누어 분석하였다. 학생의 창의성 신장을 위해서 교사는 학생들이 다양하게 사고할 수 있도록 자극할 수 있는 발문을 준비하고, 수업 진행시 하나의 발문에 대해 다수의 반응을 유도하고, 학생의 응답에 대해 단순한 '맞다, 틀리다'의 판단을 내리기 보다는 그 근거를 설명할 수 있는 기회를 마련해 주어 학생이 수학 수업에 흥미를 갖고 스스로 참여할 수 있도록 유도해야 함을 제안하였다.

This study examined different individual and environmental factors that affect children's game addiction tendency. As individual variables, game user' motivation, self-control, and self-esteem were included in the analysis. As family variables, communications with mothers, parental control of children's computer use and parental internet use were examined, as school variables, school adjustment and teacher's supervision of children's computer use, and as peer variables, peer group's attitude toward computer games were used. The sample consisted of 994 fifth and sixth grade children. Statistics and methods used for the data analysis were Cronbach's alpha, frequency, percentage, two way ANOVA, Pearson's correlation and Hierarchical Regression. Several major results were found from the analysis. First, boys were addicted more than girls. No difference was found in the addiction tendency between the 5th graders and the 6th graders. Second, game users' motivation, that is, their interest-amusement motive, avoidance motive and aggressive motive, had a positive correlation with their game addiction tendency. However, self-control and self-esteem had a negative correlation with children's game addiction tendency. Third, problematic communications with mothers and parental control of children's computer use had a positive correlation with children's game addiction tendency. Open communications with mothers had a negative correlation with children's game addiction tendency. Fourth, school adjusaent had a negative correlation with children's game addiction tendency. And peer group's attitude towards computer games had a positive correlation with children's game addiction tendency. Fifth, low self-control, peer group's attitude towards computer games, children's interest-amusement motive, avoidance motive, aggressive motive, school lesson adjustment, parental control of children's computer use and school nile adjustment were important predicting variables of boy's game addiction tendency. Avoidance motive, low self-control, interest-amusement motive, peer group's attitude towards computer games, and parental control of children's computer use were important predicting variables of girl's game addiction tendency.

The objective of this study was to review how contract farming started in Gochang-gun and identified its characteristics among the contracting parties and the consequent changes in the region's dairy industry with regard to the contract production of organic milk in Gochang-gun, Jeollabuk-do, Korea in conjunction with the Maeil Dairy Industry Corporation. The contract was established in keeping with the product diversification strategy of the company after a crisis due to opening of the market, taking advantage of the clean environment of Gochang-gun and positive attitudes of the local government and dairy farmers. The expansion of the participating farms led to a production gap among dairy farms in the region; however, the overall concern over the conventional practice of contract farming was mitigated as the organic farming spread with the conversion of the contract farms to organic farms.
