The aim of this study is to develop travel time estimation model by using Self-Organized Neural network(in brief, SON) algorithm. Travel time data based on vehicles equipped with GPS and number-plate matching collected from National road number 3 (between Jangji-IC and Gonjiam-IC), which is pilot section of National Highway Traffic Management System were employed. We found that the accuracies of travel time are related to location of detector, the length of road section and land-use properties. In this paper, we try to develop travel time estimation using SON to remedy defects of existing neural network method, which could not additional learning and efficient structure modification. Furthermore, we knew that the estimation accuracy of travel time is superior to optimum located detectors than based on existing located detectors. We can expect the results of this study will make use of location allocation of detectors in highway.

전자기장의 인체 유해성 여부가 명확히 밝혀지지 않음에 따라, 국제조직 혹은 세계 각국은 저마다의 고유한 입장에 처해 있고, 따라서 전자파 정책은 나라별로 모두 다르다. 여기에서는 각국에서 전자기장 혹은 전자파에 관하여 이슈화가 된 것들을 모아 정리하였다. 한국의 상황에 관한 자료 이외에는 모든 자료가 영어로 되어 있어, 원 자료들에서 발췌한 것들을 그대로 실었음을 양해하여 주기 바란다.

Companies with ethical management can be said to influence the performance of an organization based on the ethical judgment of its members. In this study, ethical judgment was set up as the subject of the ethical judgment, and the ethical judgment was set up by bosses and colleagues who are members of the business and organization as the factors of ethical judgment. The research was designed to examine the impact of ethical judgment on job satisfaction and organizational civic behavior, the impact of ethical judgment on organizational trust, and analyzed the medium effect of organizational trust in the relationship between ethical judgment and job satisfaction and organized civic action. The target of this study was to survey 450 workers in Seoul, Gyeonggi Province and South Chungnam Province from October 7, 2019 to November 2, using them as empirical data. The SPS 24.0 Statistical Analysis Program was used for the analysis of data. The study confirmed that ethical judgment was affecting task satisfaction, organizational civic behavior, and organizational trust, and that parameters such as organizational trust affected task satisfaction and organizational civic behavior depending on how individuals perceive the organization. Ethical judgment has a high impact on organized citizen behavior and job satisfaction, and ethical management of how to improve ethical judgment is absolutely necessary to enhance organizational citizen behavior and job satisfaction, and it is necessary to develop and implement various programs that enable a sense of unity with the organization.

The purpose of this research is to explain what affects the volunteer center's performance on the basis on the program logic model. We assume that internal factors and external factors influence the organizational performance. For the empirical analysis, we use SUR(seemingly unrelated regression). The major findings of this research are as follows: Frist, organizational budget as internal factors are important influential factors. Second, civil society's capacity variable and stakeholder's support variable affect positively volunteer center's performance. Third, the contract out variable's effect as an operation types is not proven statistically. In case of estimating the multi organizational performance, lastly, the SUR method is prefer to the OLS method in the aspect methodology. However, more systemic study is complemented the panel data for organizational performance.

This study derives the main areas of information organization that should be covered in the formal curriculum of Library and Information Science, and suggests content elements for each area. Literature research, content analysis, survey and expert evaluation were conducted. Based upon these, information organization field was composed of four areas: information organization in general, classification, inventory, and practice, and a total of 31 content elements were presented. The content elements derived from each area through this study can be used as basic and helpful data when designing syllabus or teaching subjects in the field. In addition, it is possible to expand the content elements of each area of the information organization field through the research method used in this study. Finally, the results of this study will be used as basic materials when conducting the educational contents of information organization field.

This study explored a structural model that predicted the influencing factors of GRIT and job crafting on the organizational effectiveness of organizational commitment and job satisfaction of medical center employees and verified the relationship between them. This study was conducted on 450 subjects, including doctors, nurses, administrative staff, and technical health service staff working at a university-affiliated hospital, from June 1, 2020 to June 15, 2020, and collected data were analyzed using SPSS 26.0 and AMOS 26.0. The results of this study showed that the higher the GRIT, the more active the job crafting(β=.751, p<.001), which appeared to have a positive effect on organizational commitment (β=.297, p=.005) and job satisfaction(β=.353, p<.001). Although the GRIT of medical center employees did not show a direct effect on organizational commitment and job satisfaction, indicators of organizational effectiveness and employees' job crafting thoroughly played an intermediary role in the relationship between GRIT and organizational effectiveness. These results are expected to be utilized as useful information in developing measures for human resources management of medical center employees.

The purpose of this study was to empirically analyze the effect that the job satisfaction of care workers would have on the organization commitment. For this study, 230 care workers were surveyed via mail who were working at the long-term recuperation institutes for the elderly located in the eastern part of Jeollanam-do. 141 sets of questionnaires were used for analysis, excluding those with missing data. The collected data were processed by using the SPSS 18.0 to conduct the frequency analysis, reliability analysis, t/F-test, and hierarchical regression analysis. The results of analysis suggested the followings : First, the difference in organization commitment based on individual characteristics and job characteristics of care workers was found to exist, depending on the age related to individual characteristics and types of institutes and work types related to the job characteristics. Second, hierarchical regression analysis was conducted to analyze the effect that the job satisfaction of care workers would have on organization commitment. With the individual characteristics and occupation environment variables of care workers being controlled, it was found that the job satisfaction of care workers had the greatest effect on organization commitment. This implies that the extent of job satisfaction determines the commitment level of care workers for the concerned job.
