Success in Knowledge Management depends critically on the evaluation system that managers of an organization evaluate objectively performance of members of the organization. In particular, the differences in the standard of Performance evaluation used by managers in Governmental Institution or Agency of make an issue of the standardization of Performance evaluation. Therefore, in this paper we propose the alternative evaluation method, which minimizes the bias resulted from the different standards by measuring ranking of knowledge workers, instead of quantitative analysis, using Median Rank method in Reliability and verify our proposition using the analysis of examples.

Face recognition technology has lately attracted considerable attention because of its non-intrusiveness, usability and applicability. Related companies insist that their commercial products show the recognition rates more than 95% according to their self-testing. But, the rates cannot be admitted as official recognition rates. So, performance evaluation methods and tools are necessary to objectively measure the accuracy and performance of face recognition systems. In this paper, I propose a reference model for biometrics recognition evaluation tools, and implement an evaluation tool for the face recognition system based on the proposed reference model.

The purpose of this study was to investigate the effects of the perceived facial attractiveness and appropriateness of clothing on the evaluation of task performance of target person mediated by subjects'likability toward and trait evaluation of the target person. The facial attractiveness of the female university students were used as index of physical attractiveness in this study. Three levels of facial attractiveness was manipulated based on the judgements by 30 female university students. Four types of clothes were selected perceived appropriate for two assumed situations by female university students. Three female faces having high. medium, and low attractiveness were simulated with the same body dressed four types of clothing respectively using CAD system, and a total of 12 stimulus persons were created. The design for the experiment was a $3\tiems4\times2$ randomaized factorial. with three levels of facial attractiveness(high, medium, low), and four types attire(formal-masculine, formal-feminine, casual-masculine, casual-feminine), two kinds of context (job interview, dating) in which perceptions were occurred. The subjects of this study was 524 male and female(262 of male, 262 of female) university students from 3 universities in Kwangju, Korea. The data were analysed using factor analysis. descriptive statistics, regression, path analysis. The results were as follows : 1. In bogus job interview. the direct effect of perceived facial attractiveness on task performance evaluation was .175 and the indirect effect mediated by likability and trait evaluation was .285 in path analysis model. The direct effect of perceived appropriateness of clothing on task performance evaluation was .111 and the indirect effect mediated by likability only was .0564 in pass analysis model. 2. In dating situation, the direct effect of perceived facial attractiveness on task performance evaluation was .355, the indirect effect mediated by likability and trait evaluation was .188 in path analysis model.

Objectives: The purpose of the study was to investigate the influences of job performance of dental hygienists on emotional labor evaluation. Methods: A self-administered questionnaire was completed by 203 dental hygienists working at dental hospitals and clinics in Gyeongnam and Busan from May 2014 and March 2015. The study instruments comprised general characteristics of the subjects (9 items), job performance competency (44 items), and emotional labor evaluation (29 items) by Likert 5 point scale. Data were analyzed by SPSS 21.0 program and AMOS 18.0 program. Results: Those who had turnover intention showed higher scores in the dental treatment cooperation category and overall job performance than those who had not. Higher job performance was shown in those who had more work experience and higher salary. The scores of emotional labor evaluation were higher in the group of higher salary and team and department leaders. The job performance had a significant impact of the emotional labor evaluation. Conclusions: The job performance of dental hygienists had a significant influence on the emotional labor evaluation. Psychologic stress by work caused the dental hygienists to have depression and lower quality of life.

A performance evaluation tool makes an important role in order to improve performance of an embedded software which has restricted computing resources. However, existing performance evaluation tools for embedded softwares cannot be used in collaborative development environment because they support only one developer with performance evaluation work under cross development environment. In this paper, we propose a performance evaluation tool for embedded softwares on collaborative development environment. A proposed tool is based on server and client model. It can have flexibility in offering and integrating the result information for the items. Through the suggested tool. developers can intuitively understand and analysis performance evaluation results each other.

There are many evaluation models to measure the informatization level of an organization and information system project in the ministry of National Defense of Korea. A information system has to keep up with the environment change as well as the advanced recent information technology (IT). Therefore, the evaluation of an information system project to enhance the performance of the information system should be different from the existing evaluation methods. This study suggests an evaluation case of information system projects to enhance the performance of an information system. In order to achieve the objective of this study, the following steps are taken. First, it reviews the background and the scope of the project to enhance the performance of the Defense Material Information System (DMIS). And it sets up the evaluation logic and develops performance indexes. Then it applies these newly developed performance indexes to the information system project and measures the performance. From this study, we found that both the diffusion and the experience accumulation by its continuous use are significant factors in such evaluations.

For the effective responsiveness toward Management Evaluation System of Public Institutions and continuous development as a public corporation, internal performance management is essential. In this study, the effect of employees' perceptions on the effectiveness and acceptability of the internal performance evaluation system on organizational commitment was tested, and we attempted to find implications for efficient performance management. For this purpose, we obtained valid responses from 208 members of A corporation and the hypotheses were verified through multiple regression analysis. As a result of the analysis, 'performance evaluation effectiveness' and 'performance evaluation acceptability' for internal performance evaluation had positive effects on 'organizational commitment'; however, the effect of 'differential performance compensation' on 'organizational commitment' was not significant. Also, among the control variables, 'age' and 'job group' were found to have a negative (-) effect on 'organizational commitment'. To derive more generalized conclusion, other researches using bigger samples are needed.

The most critical problem of MIS evaluation is the lack of the systematic framework to cover various factors and viewpoints. To solve this problem, this study takes the multi-level and contingent approach to performance evaluation, composed of three levels: evaluating the contribution of MIS to an organization [strategy level]; evaluating the activities of MIS department or MIS function as an organizational sub-function through the overall MIS lifecycle [function level]; and evaluating the quality or productivity of the application systems as MIS outputs [system level]. Ideal MIS evaluation should include all three levels of the hierarchy with balanced importance. However, MIS evaluationcanbedividedintothreetypes,suchasstrategy-oriented, function-oriented and system-oriented evaluation, depending on the focus and emphasis of evaluation. The usage pattern of each evaluation type is analyzed according to contingent variables of MIS evaluation such as MIS maturity, information intensity and firm size, and top management's intent. It is also found that the firms of higher MIS maturity and top management's intent use the strategy-oriented evaluation type, and the firms with strategy-oriented evaluation type show a higher MIS performance. Further, MIS maturity and top management's intent show contingent effects between evaluation type and MIS performance. Some managerial implications can be drawn based on the results of the study. First, strategy-oriented evaluation of MIS is more important as many firms more often use information technology as a strategic weapon. Second, MIS performance varies with evaluation type. Therefore, the design of MIS evaluation framework should be done carefully in the strategic and managerial contexts. Third, firms are recommend to use a different evaluation type according to organizational characteristics such as MIS maturity and information intensity.

Positron emission tomography-computed tomography (PET/CT) provides both functional and anatomical images of high quality non-invasively with better precision in localization than PET alone. Increase in the use of PET/CT, coupled with increasing concerns about the quality of medical services accrued the demands for accurate evaluation of system performance and quality assurance. Thus, well designed programs for performance evaluation and quality assurance are needed. Widely used protocols for performance evaluation of PET are the methods proposed by National Electrical Manufacturers Association (NEMA) in 1994 and 2001. In addition, in order to maintain high quality of PET/CT images, quality assurance programs including periodic (daily, monthly, and yearly). Therefore, in this article, the methods and present state of performance evaluation and quality assurance of PET/CT are reviewed.
