Present study conducted surveys and interviews to identify a solution to the issues concerning the work conditions, job satisfaction, and operational systems of archivists working in the Korean government agencies. Job characteristics were measured using the five-factor structures of Hackman and Oldham's(1976) Job Characteristic Models, professionalism, role conflict, stress, and turnover intentions. Job environment was measured in terms of communication, participation, social relations with coworkers and superiors, and job training. Job satisfaction was measured by general level of satisfaction, job meaningfulness, and commitment. Operational systems was analyzed in terms of organizational arrangement, role assignment, personnel management, and collaboration between the national archives and record centers. These analyses produced further implications and suggestions on personnel management of archivists and records managers.

The purpose of this study is to analyse the cases related with PBL and to suggest the activation plan of LAI based on the derived results. The analysis objects were the PBL cases which have been performed from 2000 to 2018 in Korean schools. The PBL cases were analysed in the aspects of school levels, target grades, subject clusters, teaching patterns, information sources, cooperative teaching status, library cooperative teaching status, and educational effects. The results were like these; 1)The PBL was applied at the elementary schools the most, the next middle schools, and high schools. 2)The teaching pattern was the exclusive teaching the most, and the next pattern was team teaching with other teacher, and the lowest pattern was with librarian teacher. 3)The subject cluster was natural science cluster the most and the next was the human & social science cluster and the art, music and physical education cluster. 4)The PBL performed with school library was low. 5)The main effects of PBL were the improvements of academic achievement, learning satisfaction degree, creative ability, problem-solving ability, and self-directed learning capability. As the results, it's proposed that it's important for librarian teachers to have the aggressive attitude for the activation of LAI as well as the cooperation with PBL subject teachers from the planning step to the evaluation.

This study aims to examine the relationship between the expertise of track and field coaches, the team atmosphere, and athletic satisfaction in elite sports. To achieve this research purpose, data were collected using questionnaires from 221 student athletes from junior high to university students registered with the Korea Association of Athletics Federation in 2021 and collected using Google online questionnaires in consideration of the pandemic situation. For data processing, frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis, and multiple regression analysis were performed using the statistical program SPSS 22.0, and the following conclusions were drawn. First, it was found that the expertise of the athletics coaches had a positive (+) effect on the team atmosphere. Second, among the sub-factors of athletics coach expertise, only athlete management was found to have a negative (-) effect on daily life satisfaction, a sub-factor of athletic satisfaction. Third, it was found that among the sub-factors of the team atmosphere, only role characteristics and leader characteristics had a positive (+) effect on social approval satisfaction, a sub-factor of athletic satisfaction.

The purpose of this study is to analyze components of conflicts and investigate causes of them between mentor teachers and mentee teachers, who participated in the collaborative mentoring program to improve beginning science teachers teaching practice. The most often occurring component of conflict for surveyed teams was class strategy on knowledge of teaching methods. Then, conflicts in understanding student characteristics as a component of understanding students and knowledge transfer of concepts in science as a component of teaching contents followed as main causes. Changes in conflicts showed that less frequency of conflict occurred with ongoing mentoring. Conflicts from class strategy decreased the most, which had been the most often occurring cause. This decrease was explained as mentees were changed gradually into the teacher's role recognition through continuous mentoring. This study suggests that education for mentor and mentee teachers be provided with consideration of causes of conflicts and reasons for those causes, which eventually lead sustainable and efficient mentoring program management.

For operation of IEEE 802.22 WRAN system, spectrum sensing is a essential function. However, due to strict sensing requirement of WRAN system, spectrum sensing process of CR nodes require long quiet period. In addition, CR nodes sometimes fail to detect licensed users due to shadowing effect of wireless communication environment. To overcome this problem, CR nodes collaborate with each other for increasing the sensing reliability or mitigating the sensitivity requirement. A general approach for decision fusion, the "k out of N" rule is often taken as the decision fusion rule for its simplicity. However, since k out of N rules can not achieve better performance than the highest SNR node when SNR is largely different among CR nodes, the local SNR of each node should be considered to achieve better performance. In this paper, we propose two novel data fusion methods by utilizing confidence vector which represents the confidence level of individual sensing result. The simulation results show that the proposed schemes improve the signal detection performance than the conventional data fusion algorithms.
