The Korean government amended the Facilities Safety Act in 2018 to establish a performance-based maintenance system. This system is designed to comprehensively evaluate the safety, durability, and usage performance of facilities required to maintain their function in use, and to establish corresponding maintenance plans. However, the current maintenance system of utility tunnels is managed by a safety-oriented evaluation method, which has limitations in conducting performance evaluations that consider durability and usage performance. Therefore, in this study, safety, durability, and usage performance items for utility tunnels were selected using the Delphi method, and the weight of each item was calculated using the entropy weighting method. The results of this study are expected to be used in future performance evaluations of utility tunnels to support rational decision making when establishing maintenance plans.

One of the important performance metrics of the World Wide Web is how fast and precise a request from users will be serviced successfully. Shared Web Caching (SWC) is one of the techniques to improve the performance of the network system. In Shared Web Caching Systems, the key issue is on deciding when and where an item is cached, and also how to transfer the correct and reliable information to the users quickly. Such SWC distributes the items to the proxies which have sufficient capacity such as the processing time and the cache sizes. In this study, the Hot Spot Prediction Algorithm (HSPA) has been suggested to improve the consistent hashing algorithm in the point of the load balancing, hit rate with a shorter response time. This method predicts the popular hot spots using a prediction model. The hot spots have been patched to the proper proxies according to the load-balancing algorithm. Also a simulator is developed to utilize the suggested algorithm using PERL language. The computer simulation result proves the performance of the suggested algorithm. The suggested algorithm is tested using the consistent hashing in the point of the load balancing and the hit rate.

Purpose: This study aimed to empirically demonstrate how self-esteem, self-efficacy, locus of control, and neuroticism, which is core self-evaluation factors of door-to-door salespersons within food and cosmetic retail industry, affected the sales performance of female salespersons via job satisfaction and organizational commitment. Research design, data and methodology: Using a 23-item questionnaire constructed based on previous studies, this study selected six domestic door-to-door sales companies and conducted a 1:1 face-to-face survey with female door-to-door salespersons belonging to branches and agencies in Seoul and the capital region. The data of 208 respondents were analyzed. The results of path analysis based on structural equation modeling and mediation analysis through the Sobel test were presented. Results: Self-efficacy and locus of control had the largest effect on job satisfaction and organizational commitment, respectively. Neuroticism, however, did not significantly influence job satisfaction and organizational commitment. Overall, core self-evaluation factors positively affected sales performance via job satisfaction but not via organizational commitment. Conclusions: This study found that factors which were oriented to female salespersons' ability and sales goals, such as self-efficacy and job satisfaction, were considered important in managing them in the door-to-door sales-distribution channels. In the future, policies should be developed for managing female door-to-door salespersons to help them achieve job satisfaction.

Purpose: The aim of this study was to share the experience of clinical performance examinations (CPXs) using standardized patients, which was to test comprehensive clinical competence of fourth-year nursing students for four years. Methods: The assessment strategies for CPXs were developed. It included clinical scenarios, the roles of standardized patients, and appraisal criteria in the areas of fundamental and comprehensive nursing care. The CPXs were implemented to about 60-70 fourth-year nursing students of C University in G-city, South Korea, during every second semester from the year of 2006 to 2009. Results: The effects of CPXs were measured by 10 or 25-item rating checklist. Internal reliability of the checklists was distributed from .511 to .956 and interrater agreement between faculties and standardized patients was moderate (r=.250-.949). Students' satisfaction level was 4.27 out of 5 points for four years. Conclusion: The use of CPXs was an innovative educational strategy to evaluate nursing students' comprehensive performance ability including knowledge, skills and attitude. Further studies are needed to evaluate the levels of critical thinking and problem solving skills of clinical nurses who were taken CPXs as well as employers' satisfaction.

We proposed a specialized model of performance measurement to measure the training performance of the trainees in cyber practical training. Cyber security professionals are cultivating their expertise, skills, and competencies through cyber practical training in specialized education and training institutions. The our proposed process of trainee evaluation is consisted of an evaluation component discovery, evaluation item selection, evaluation index catalog, ratings and criteria decision, and calculation formula. The trainee evaluation is consisted of a formative evaluation during the training and an overall evaluation after finished training. Formative evaluation includes progress evaluation and participation evaluation, and overall evaluation includes practice evaluation and learning evaluation. The evaluation is weighted according to the importance of evaluation type. Because it is evaluated actual skills and abilities, competencies are assigned a high weight, while knowledge and attitudes are assigned a low weight. If cyber security trainees are evaluated by the proposed evaluation model, cyber security professionals can be cultivated by each skill and knowledge level and can be deployed by importance of security task.
