The objective of the present study is to investigate the relationships among the perceptions of performance appraisal politics(POPAP)), employee's attitude to work, and team-based work system characteristics. Using survey data from various occupationally heterogeneous sample of white-collar employees(N=195) from various organizations, the results indicate that when employees perceive performance rating to be manipulated because of rater's personal bias and punishment motive, they reduce organizational commitment. Contrarily, the employees' POPAP with motivational motive increases organizational commitment. And task interdependency has positive effect on employees' POPAP.

Objective : The purpose of this study was to investigate the effect of occupational therapy intervention using a fully immersive virtual reality device on the upper extremity function of patients with chronic stroke. Methods : This study used a single subject (ABA) design. The study subjects was a chronic stroke patient with left lateral deviation. Four baseline periods, 12 intervention periods, and 4 baseline regression periods were performed for a total of 20 sessions for 10 weeks. OT intervention with a fully immersive virtual reality device was used every 30 minutes. BBT and WMFT evaluations were performed at each session and the results were displayed in a line graph. Results : The patient's upper limb function has improved. During baseline recurrence, efficacy of treatment was confirmed after removal of intervention, but no significant changes were observed. Conclusion : It has been found that OT intervention with a fully immersive virtual reality device for upper limb function in chronic stroke patients is an effective intervention. However, the effectiveness of maintaining treatment is not important, so we need to develop an easy-to-use home intervention program.

The current study investigated mediating effects of self-regulatory system in the context of public service announcements (PSAs). We conducted a survey to collect participants' orientation of self-regulatory systems, emotional response and evaluation of PSAs. A total of 70 undergraduate students with mean age of 22.49 (SD = 3.22). Results showed that emotional engagement to the PSAs is affected by ad liking and, in turn, directly influences intention to act as a campaign outcome. Furthermore, our findings suggested that promotion-oriented individuals are more likely to commit PSA messages than do the prevention-oriented individuals. Therefore, messages of the PSA campaign should include hope and aspiration, indicating the connection of accomplishment and advancement.

The purpose of the present study was to examine the effects of full immersion virtual reality (VR) on the autonomic nervous system. The study was conducted with 17 men in their 20s. The subjects were given full immersion VR content, and electrocardiogram (ECG) signals were measured for five minutes before and after the application of the full immersion VR. The autonomic nervous system was evaluated by analyzing the LF, HF, TP, and LF/HF ratio of the ECG signal. The obtained data was analyzed by conducting a paired sample t-test. After applying full immersion VR, the subjects' HF and TP decreased significantly, while their LF/HF ratio increased significantly. According to the results of this study, Full immersion VR provided stress to the autonomic nervous system, but the changes were within the normal range of healthy adults. Therefore, full immersion VR can be safely applied to healthy adults.

The purpose of this study was to gather basic data and measure job satisfaction and job engagement of dietitians and nutrition teachers in Chungbuk area. This study was conducted on 20 August, 2010. Out of 336 questionnaires, 266 were completed and made available for the purpose of statistical evaluation. As the main results, job satisfaction was classified into eight categories: task, wage, policies related to tasks, professional growth, promotion, relationships with colleagues, working environment, and supervision. In the case of wage, promotion, and policies related to tasks, the average scores of job satisfaction were around 2 points out of 5. Dietitians' job satisfaction levels according to employment type and school type significantly differed. In terms of job involvement and organizational commitment, average scores were 3.53 points and 3.12 points respectively. The survey showed significantly different results for job involvement and organizational commitment, depending on employment type, school type, and status as chef in charge or trainee. Dietitians working in elementary schools, as chef in charge, or with permanent employment showed higher job involvement and organizational commitment.

This study aims to empirically verify the positive impacts of PB(performance-based) HRM on the organizational effectiveness in a public corporation. The independent variables are 'PB staffing', 'PB appraisal', 'PB compensation'. The dependent variables are 'JS(job satisfaction)', 'OC(organizational commitment)'. The results are as follows. 'PB staffing' shows positive impact on both 'JS' and 'OC', but 'PB compensation' doesn't show positive impact on both 'JS' and 'OC'. Also, it is found that both 'PB appraisal' and 'PB compensation' do not show positive impact on 'OC'. 'PB appraisal' shows positive impact on 'JS', though. From the empirical analysis, the positive effects of the PB-HRM on the organizational effectiveness are partially verified. It is thought that these mixed results are originated from the particular situation in which the surveyed corporation is placed. After the merger of the corporation in 2009, even though it has introduced various PB-HRM systems, it has been through a harsh time such as wage freeze and return as measures of business normalization. This organizational situation may influence the verification of effectiveness of the normal PB-HRM.

최근 WEB 2.0 환경을 통해 사용자는 직접 응용 프로그램과 데이터를 이용하여 새로운 컨텐츠를 생산하는 주체로 변모하고 있다. 이러한 사용자의 자발적이고 적극적인 참여는 'UCC(사용자 제작 컨텐츠)'라고 불리는 새로운 문화 컨텐츠의 활성화로 이어지고 있다. 특히 글과 그림, 소리 등이 총체적으로 엮여 있는 동영상 UCC 의 경우, 이야기 구조나 캐릭터가 갖는 내용적인 특성과 제작자의 제작 취지를 훼손없이 살릴 수 있다는 제작의 특성으로 인해 WEB 2.0 환경에서 사용자의 참여가 더욱 두드러지고 있다. 본 연구에서 '사용자들이 열광하는 동영상 UCC 는 어떤 특징을 갖는가?' 라는 질문에 답하기 위해 동영상을 시청하는 사용자의 몰입과 창의성 평가를 진행하였고 이에 영향을 주는 요인으로 동영상 UCC 를 구성하는 내용적인 특성인 이야기의 내러티브와 캐릭터의 과장성을 살펴 보았다. 그리고 이 요인들의 상호작용에 영향을 주는 매개변인으로 제작자의 제작의도에 따른 컨텐츠의 특성을 선정하였다. 제작자의 의도에 따른 컨텐츠의 특성을 분류하기 위해 라캉의 주체이론과 퍼스의 기호학 이론을 바탕으로 모형을 제안하였으며 이를 검증하기 위해 UCC 사용자들을 대상으로 현재 서비스 중인 동영상 UCC 를 보여주고 설문을 실시하였다. 연구결과 제안하는 모형의 적용가능성이 입증되었으며 제작자의 의도에 따른 컨텐츠의 특성에 따라 이야기의 내러티브나 캐릭터의 과장성이 사용자의 몰입과 창의성평가에 미치는 영향력이 다르게 나타나는 것을 확인할 수 있었다.
