본 논문에서는 가상환경에서의 바둑 게임을 위하여 CyberGlove와 트랙킹 장비를 이용한 사용자 인터페이스를 구축하고 이의 사용성을 평가하였다. 먼저 바둑 게임을 위한 3차원 객체들을 생성한 후, WorldTookit을 이용하여 가상환경을 구축하였다. 그리고 트래킹 리시버가 부착된 CyberGlove를 끼고 바둑함으로부터 "바둑알 집기"와 바둑판 위의 화점에 "바둑알 두기"를 통해 가상환경에 익숙치 않은 사용자들을 대상으로 인터페이스의 사용성을 평가하였다. 실험 결과 현실 세계와 같이 손과 손가락을 움직여 바둑을 두는데 매우 흥미로와 했고, 사용자의 2가지 뷰에 따라 실험한 결과 직교 top 뷰에서의 정확도가 대각 원근 뷰 보다 높게 나타났다. 또한 주변 화점에 바둑알을 둘때의 정확도가 현저히 저하됨을 알 수 있었다. 장기간 사용시 불편함 호소 등 해결해야할 문제가 있음에도 불구하고 가상현실 인터페이스는 보다 몰입적이고 현실감 있는 게임을 위해 필요한 요소임을 확인할 수 있었다.

Purpose: This study was an analysis of the relationship between perception for appraisal of staff nurses in operating rooms and performance and organizational commitment. Method: The survey was conducted with 176 staff nurses in operating rooms in 2 hospitals in Seoul. Data were analyzed using frequency, one-way ANOVA, Pearson correlation analysis, and stepwise multiple regression. Result: 1. Perception for appraisal including accuracy and justice was significantly related to organizational commitment (r=.496, P=.000). Perception for appraisal including accuracy and justice was slightly related to performance (r=.220, P=.003). 2. In order to determine the percentage of the variance of performance and organizational commitment that could be predicted by perception for appraisal, perception for appraisal was entered in the regression equation. Accuracy accounted for 25% of the variance in the organizational commitment. To determine the percentage of the variance of performance that could be predicted by perception for appraisal and organizational commitment, the perception for appraisal and organizational commitment were entered in the regression equation. Organizational commitment accounted for 21% of the variance in the performance. Consequently accuracy predicted organizational commitment. Organizational commitment predicted performance. Conclusions: Findings indicate the need to increase accuracy of performance appraisal to promote organizational commitment and performance in perioperative nurses.

Multimedia element of the game graphics and sound, etc. 'commitment' that plays an important role in gameplay. Therefore, the quality of the game is closely related to the quality of multimedia elements that can be. In this study, various competitions in the field of content screening criteria based on previous studies and multimedia elements of the game area, and domain-specific details about the quality of sub-elements were extracted. Assessment areas and sub-elements extracted to verify the need for the game will be carried out surveys among the users. The findings in the next game production shall be deemed to be an important reference material.

Objective : This study aimed to develop evaluation items based on Parten's social play developmental stages to measure social play in preschool children. Methods : Through a literature review, the investigation items according to Parten's social play developmental stages were collected. Two Delphi surveys were conducted using 22 expert panels. An understanding of the contents of the preliminary items was determined via parents of preschool children. The evaluation method was established through an expert advisory meeting. Results : Through data collection and the Delphi survey, a total of 89 items were drawn, including 12 unoccupied behaviors, 7 onlooker behaviors, 14 solitary play, 16 parallel play, 17 associative play, and 23 cooperative play items. The average content validity ratio of the Delphi survey was 0.85. The stability was 0.15. The consensus was 0.78. The final preliminary evaluation items comprised a total of 40 items, including 17 for associative play and 23 for cooperative play. Conclusion : An evaluation items that can measure social play in preschool children was developed, and its content validity was verified. It is expected to be used as an evaluation tool in clinical practice.

Immersive media videos, such as panorama and 360-degree videos, must provide a sense of realism as if the user visited the space in the video, so they should be able to represent the reality of the real world. However, in panorama and 360-degree videos, objects appear to overlap or disappear due to parallax between cameras, and such parallax distortion may interfere with immersion of the user's content. Accordingly, although many video stitching algorithms have been proposed to overcome parallax distortion, parallax distortion still occurs due to the low performance of the Object detection module and limitations of the Seam generation method. Therefore, this paper analyzes the limitations of the existing video stitching technology and proposes a method for detecting and correcting parallax distortion of video stitching using the LDPM (Local Differential Pixel Mean) image evaluation method that overcomes the limitations of the video stitching technique.

The purposes of this study were to: a) provide evidences concerning the effects of emotional leadership b) examine the impacts of emotional leadership on employee-related variables, 'job satisfaction', 'organizational commitment', 'organizational performance' and 'turnover intention', and c) identify a conceptual framework underlying emotional leadership. A survey was conducted from August 23 to November 3, 2005 to collect data from mid-level managers in food service company headquarters (N=219). Statistical analyses were completed using SPSS Win (12.0) for descriptive, reliability, factor and correlation analyses and AMOS (5.0) for confirmatory factor analysis and structural equation modeling. The main results of this study were as follows. First, the managers gave the highest point to their leaders in the emotional leadership competence 'organizational awareness : reading the currents, decision networks, and politics at the organizational level' and gave the lowest point in the emotional leadership competence 'influence: wielding effective tactics for persuasion'. Second, the means of job satisfaction was above the midpoint (3 points). Employees' job satisfaction with 'coworkers' was relatively high. However, the extents of satisfaction with 'payroll' 'promotion', and 'work environment' were relatively low. Third, the organizational commitment was above the midpoint (3 points). In the organizational commitment, 'loyalty' factor was higher than 'commitment' factor. Fourth, the means of organizational performance was above the midpoint. The highest organizational performance variable was 'internal efficiency; trying to reduce cost' and the lowest organizational performance variable was 'internal fairness ; equitable treatment and all are treated with respect with no regard to status and grade'. Fifth, most respondents intended on 'thinking of quitting ; towards turnover process'. Sixth, the test of hypothesis using structural equation modeling found that emotional leadership produced p[Isitive effects on job attitude and job performance. Emotional leadership enhanced job satisfaction and organizational commitment, and in turn, employees' attitude positive effects on organizational performance; emotional leadership also had a direct impact on organizational performance
