The purpose of this study is to understand the changes from adopting daily two-shift roster in child care institutions. To accomplish this purpose, we collected data mainly from depth interview with managers, child care workers, and children in child care institutions adopting daily two-shift roster, and analysed these data through qualitative case study approach. The results of this study are as follows. First, child care workers take the chance of recreation, their working conditions improved, they were participated in self-development activity, and they could make relationship with persons in social network. But, some participants worried about decrease of responsibility of workers. Second, one hand, possibility of high-quality care for child is increased, on the other hand, possibility of improving attachment relationship between workers and children is decreased. some children is confused by shift. But, most important strength is that partners have complementary parenting roles through discussion about parenting skills. They have developed communication skills by trial and error, and growed with children through sharing. Third, many qualified persons have applied for institution because of improvement of working conditions, thus institutions had the chance of adopting qualified workers. These workers have various abilities and resources, could mobilize resources from community, and could progress various programs and intervene for children. But, institutions had many difficulties in process adopting daily two-shift roster because of unstable financial support and previous structure. Most of participants worried about that local government may cut down a subsidy.

Archival reference service is the ultimate goal and outcome of records management. It encompasses a whole range of activities to connect records with the demands for them. Intellectual needs for records are met by the procedure of information disclosure to guarantee the people's right to know and to provide active responses to archival information needs. Thus, it is required to establish an efficient search system by unifying search tools for archives used in information disclosure and sorting out the classification systems and description items according to the archive types. The qualitative enhancement of information disclosure can be expected when there is a harmonious circulation of attributes-such as applicants, records, search tools, and information providers-for the smooth implementation of reading processes in the context of archival reference service. Therefore, the present study holds its significance in the following aspects. First, it presented a picture of pending issues and the reality of reading service processes from an internal perspective by examining the factors and characteristics that influence "reading service."Second, it demonstrated the phenomenon of close interactions among information providers, applicant, search tools, and records in the process of requesting, searching, and providing records. Third, it proposed the need for a total integrated search tool around the pending issues of reading processes at the National Archives of Korea. Fourth, it promoted an understanding of archival information utilization at the working level among information providers. Finally, it showed major differences in the quality of information provision of "reading service" according to the "perceptions" and "attitudes" of information providers.

An increase of national R&D has brought the growth of research performance such as paper and patent quantitatively. However, the results of technology transfer and commercialization still leave much to be desired in Korea. Therefore, it has to be drawn up a plan for effective management & application of research performance created by public research institutes. We select four leading institutes (two universities, two government-funded research institutes) that performed efficient performance management & application. Then, we analyze the best practices and suggest contributions. The results show that four institutes build up a framework of performance management & application from research planning to technology transfer and commercialization. At an early planning phase, institutes set up definite needs-oriented goals, and prior review as well as prior art search is executed through experts. Besides, they systematically promote strategic patent management, technology marketing, post management, and so forth. For such a performance management & application process, capabilities have to be supported with regard to specialized organization, system, routine. This study can give an hint to improve performance management & application from public research institutes in Korea.
