This study was conducted to analyze the effects of person-environment fit on the job performance in the National Assembly legislative support organization. Job performance was classified into task performance, contextual performance, and adaptive performance. Impacts of each factors on the job performance were identified through structural equation model. From the results of analysis, it was confirmed that supplementary fit of officials of legislative support organization of the National Assembly had a positive effect on task performance, contextual performance, and adaptive performance. However, complementary-fit does not directly affect task performance, contextual performance, and adaptive performance. Rather complementary-fit affects job performance by the mediating role of variable self-efficacy. The implications of this study confirm that it is important to match between organization members and jobs in order to improve the job performance of civil servants in the legislative support organization. The necessity of introducing self-efficacy enhancement program into the education and training process of the legislative support organization was proposed.

Using open-ended questionnaires, two studies were conducted to explore social representations held by Korean undergraduates on children, adults and adolescents. Study 1 compared between children and adults with responses reported by 97 undergraduates(men: 28, women: 69). According to the results, characteristics of children distinctive from adults were basically personality-related and in particular, typical children were marked by high extroversion, low agreeableness, conscientiousness and culture. Further, happiness for both children and adults was determined mainly by interpersonal relationships, physical health and socio-economical status. However, good(or desirable) children characteristic of high agreeableness and conscientiousness were more similar to adults worthy of the name than to children worthy of the name. Using 57 undergraduates(men: 16, women: 41), Study 2 explored social representations of adolescents. The results indicated that overall adolescence were on the bridging state between childhood and adulthood. Happiness for adolescents, like both children and adults, was determined mainly by interpersonal relationships and socio-economical status. Finally, agreeableness, conscientiousness, self-, task- and relationship-related characteristics were involved in judging good(or desirable) adolescents. These findings were discussed in terms of features of Korean culture and human development.

Startup has lot of limitation such as time and budget shortage, and few human resources, and may be under the very stressful condition. Naturally in these context, there is always conflict among the startup team members, but the impact of conflict on teamwork or team performance has not been empirically tested. This study examines the relationship among the conflict, teamwork and team performance in startup context. Different two types of conflict and four factors of teamwork for team performance are identified from a literature review and tested; task conflict and relationship conflict as antecedents, teamwork was composed of communication, collaboration, coordination and cohesion, leading to team performance. 142 data points were collected from startup representatives to test these hypotheses. PLS data analysis indicated that the task conflict positively effects on all teamwork factors, but relationship conflict has statistically significant effect on only two teamwork factors, collaboration and coordination in negative relationship. Teamwork factors effects on team performance except communication. Based on the results, we proposed practically several team management skills for startup managers, leaders and even members, and explained theoretical contributions.

The purpose of the present study was to investigate the characteristics of disfluency in 3~5 year-old multicultural family children(MFC). 24 children(12 MFC, 12 Korean monolingual children, KMC with the same chronological age and language age) participated in this study. The experimental tasks consisted of story retelling tasks(SRT) and picture description tasks(PDT). In all the tasks, the scores of total disfluency of the MFC were significantly higher than those of the KMC. In all the tasks, the frequency of abnormal disfluency of the MFC were significantly higher than those of the KMC and the speech rates of the MFC were significantly lower than those of the KMC. The disfluency observed in MFC indicates that language ability influences on their disfluencies and fluency support of MFC is an important factor in general language support.

This study had three purposes. First, the effects of job-related affective states on emotional labor (deep acting and surface acting) of employees engaging in service job were examined. Second, previous studies focused on the negative effects of emotional labor on job attitudes. On the other hand, this study dealt with not only the negative effects of emotional labor but also its positive effects. In particular, this study examined the effects of emotional labor on positive job attitudes, such as job commitment and job involvement, as well as negative job attitudes, such as exhaustion and cynicism. Finally, this study examined the mediation effect of emotional labor on the relationship between the job-related affective state and job attitudes. The data was collected from 150 employees working in 15 service firms in Korea. The results were as follows. First, the positive job-related affective state increased the deep-acting. On the other hand, negative job-related affective state increased surface-acting. Second, the main effect of deep-acting on positive job attitudes (dedication and vigor) was significant. In addition, the main effects of surface-acting on the negative job attitudes (exhaustion and cynicism) was significant. Finally, the mediating effect of deep-acting on the relationship between positive job-related affective state and positive job attitudes was significant. In addition, surface-acting mediated the relationship between negative job-related affective state and negative job attitudes. The theoretical and practical implications of this study are provided in the discussion session.

우리 군은 창군이래 최대 규모의‘국방개혁추진위원희’를 편성·운영 중에 있다. 차제에 이 글은 군 개혁의 참고모델로서‘이스라엘의 군대’를 제시하여 군 개혁과업을 추진하는데 다소라도 기여하고자 한다. 이스라엘은 지난 50년간‘자주국방’의 정신으로 군사력을 꾸준히 발전시켜서 오늘날 전세계에서 작지만 가장 당찬 정예화군·기술군·과학군을 창조했다. 한국도 지난 50년간‘자구국방’을 위해 부단히 노력한 끝에 이제 외형적으로는 세계 10위권의 큰 군대가 되었다. 그러나, 양국이 지난 50년간 노력하여 만들어 낸 현재의 최종 산출물, 즉 전력수준과 군사태세는 양국의 지닌 저마다의 불가피한 특수한 사정이 있었지만 결과만을 놓고 볼 때는 이스라엘 군이 우리 군보다 우월한 것으로 보여진다. 우리는 우리보다 훨씬 작은 이스라엘이 우리보다 비교 우위의 군사력과 군사태세를 보유하고 있는 이유를 찾아내야 한다. 왜냐하면 그 이유가 곧 우리 군을 개혁해 나가는 데 있어서 참고해야 될 주요 지표가 될 수 있기 때문이다. 이와 같은 관점에서 이 글은 이스라엘의 특수한 안보환경과 건국과정을 살펴본 다음, 이스라엘 군의 특징 및 우수성을 분석하고, 우리 군이 개혁과업을 추진해 나갈 경우 참고될 수 있는 몇 가지 시사점을 개념적 차원에서 제시하였다.

This study highlights the main effect of job demand, work shift, work environment and stressors on the railway traffic controller's health, and the moderating effect of work0life balance. The result of empirical analysis based on questionnaires received from 328 traffic controllers working at 10 railway operating companies indicates that job demand, work shift, work environment and stressors have significant effect on their health, among which stressors is a major factor. In the respect of moderating effect, WLB showed no significance except for job demand. This result implies that controller's health can not be enhanced through their individual family or leisure life. Therefore, effective countermeasures and policy to mitigate their health problems and heal their symptoms are urgent.

It is expected that expanded use of smartphone and enhanced information technology will enable smartwork to change individuals and organizations. Smartwork is expected to allow people to perform their roles without barriers of time and space. However, people tend not to accept and actively utilize smartwork. The present study is to examine how important flexibility-willingness is for performance outcome in the context of smartwork. It was hypothesized that flexibility-willingness mediates between perceived smartwork usefulness and work-family conflict. It was also hypothesized based on technology acceptance model that task interdependence and process control moderates the relationship between flexibility-willingness and work-family conflict because the relationship is not consistent. The results show that the mediation effect of the flexibility-willingness is statistically significant. The moderator effects of task interdependence was marginal proved but process control wasn't. From these results, we discussed the theoretical implications of findings, limitations, suggestions for future research in discussion.
