To improve nuclear transplantation(NT) efficiency and to produce a large scale genetically identical cloned calves, examined the in vitro development capacity after co-culture of bovine oviductal epithelial cells (BOEC) and granulosa cells in TCM-199 supplemented with 10% fetal calf serum (FCS) with early bovine embryos derived from in vitro matured fertilized(IVM-IVF) oocyte. In addition, the age dependence of IVM oocyte on electro-stimulation and the effective electric voltage on in ivtro development of bovine NT embryos were examined. The results obtained were summerized as follows; 1. The cleavage rates of IVM-IVF bovine embryos in co-culture with bovine oviductal epithelial cells and granulosa cells were not significantly different(P<0.05), but the developmental rate into morula and blastocyst stage were different showing 38.3 and 20.2%, respectively. 2. The activation (82.5%) and development in vitro(8.6%) into later embryo stages of the aging oocytes of 32 hours post-maturation (hpm) were significantly higher than those of 24 hpm at direct current (DC) voltage of 1.5kV/cm, 60$\mu$sec pulse duration and 1 pulse time. 3. The fusion rates of NT eggs of 32 hpm following to different DC voltages from range 0.75 to 1.5kV/cm were not differ, but the developmental rate into morula and blastocyst stages at DC voltages of 0.75 and 1.0kV/cm were higher(11.4 and 12.6%, respectively) than those of 1.5kV/cm(0%). From these results, it can be suggested the optimal culture system for in vitro culture of IVM-IVF bovine embryos is a co-culture system with BOEC in TCM-199 supplemented 10% FCS. The effective time and the DC voltage for activation, electrofusion and in vitro development of NT embryos derived from IVM-IVF bovine embryo are 32hpm and 0.75~1.0kV/cm. But to improve NT efficiency, the advanced research (cell cycle synchronization, micromanipulation, culture system, etc.) is needed.

The purpose of the this study was to investigate and analyze the various statistical data on the actual state of farmland uses given in Korea and Hokkaido of Japan. The results of this research are as follows ; 1. The rate of farmland uses was marked 118% and 99% in Korea and Hokkaido of Japan in 1988, respectively. That of Korea was higher than that of Hokkaido of Japan. The tendency of the value for Korea has been decreased since the value was shown peak in 1980, but that of the value for Hokkaido was found gradually the increased value. It was analyzed that the reason why the value was decreased in Korea was referred to avoid the crops culture, and the reason why the value was increased in Hokkaido was dueto increase the area of pasture. 2. The farmland use system according to region were d ue to be the mixing pattern of rice culture and dry-field crops in East region of korea and the type of mainly rice culture in West region. The pattern of farmland use system was used to be performed mainly the rice culture in Central region, the mixing type of rice culture and dry-field crops in South region, and the agriculture of mainly dry-field crops and dairy in East-North region in Hokkaido. 3. In the light of the rate of planting, the rate of rice culture and dry-field crops were 49% and 51% in Korea, respectively. As the values were 13% and 87% in Hokkaido of Japan, respectively, the dry-field crops attained the superiority. The main crop kinds was shown the rice culture in Korea and the feed plant in Hokkaido of Japan, respectively. 4. In considering the above results, there are much differences in agricultural style and industrialization processes in both country Korea and Japan. Especially much more differences were evident from farmland use system of Hokkaido Island where had unique agricultural style in Japan.

Objective: The objective of this research is to inquire about safety information from the standpoint of its usefulness to suggest the significance of the Reactive Safety Action Program, which serves to promote aviation safety culture. Background: Safety information plays an important role in operating safety programs. Each organization learns lessons from safety information collected from aviation accidents and incidents. When an accident occurs, it is only through safety investigation and a close inquiry on the cause that we can come up with an appropriate countermeasure which would contribute to preventing the recurrence of the same or similar accident. However, the usefulness of safety information produced from unsatisfactory safety investigation is insufficient. Method: This research analyzed the characteristics of aviation accidents, the differences between safety investigations and legal accident investigations in systematic and operative perspectives, and safety culture as a measure to activate reporting systems (compulsory/voluntary). Results: This research defined the investigation scope and processes of safety investigations and legal accident investigations. It also suggested factors such as just culture based on trust, non-punitiveness, confidentiality, the participation of the entire staff through the use of inclusive reporting base, ensuring the independence of the operating organization as a way to promote safety through reporting systems. Conclusion: The organization's effort is the important aspect in obtaining exact and accurate safety information from accidents/incidents. The separate running of SIB (Safety Investigation Board) and AIB (Accident Investigation Board), the systematization of safety information reporting system, and prescribing (legislating) the composition of related organizations are some representative programs. Application: This research inquired experiences that contributed in promoting aviation safety culture in a reactive perspective, and will serve a role in spreading safety culture by enabling the use of application experiences of the aviation field in other domains.

The free learning semester system focuses on the activation of career education of middle school students as an educational policy that links career recognition in elementary school, career search in middle school, and career planning in high school. This system was fully implemented in 2016 and public libraries also provided various programs. This study analyzed the free learning semester system programs of public libraries in Busan city and demonstrated the contribution of local development. As a result, career and job search, career exploration and experience, and information literacy enhancement programs contributed to local knowledge culture, reading culture, learning culture, living culture and leisure culture. However, contribution of reading exhibitions, job experience, information literacy enhancement to the leisure culture and local economy were limited. Therefore, it is desirable that all libraries should add programs related to knowledge ecosystem structure, digital information gap, human healing, social environment issues, future job prospects, and provide information literacy programs.

The purpose of this Study is to present the tasks and means of improving the operational system of public culture and arts institutes in the future on the basis of the analysis of the effectiveness of operation of public culture and arts institutes. The summary of the results of analysis in this Study is as follows: Firstly, it was found that the factor variables that impart effect on the operation of public culture and arts institutes included (1) artistic value, (2) convenience and (3) organizational management, while the performance variable of public culture and arts institutes was (4) operational performance. Secondly, in the analysis of the structure that explains the operational effects of public culture and arts institutes, convenience and organizational management were found to impart effects on the operational performances. However, artistic value was found to have no effect on operational performances. Therefore, these results of analysis imply that organizational management and convenience, rather than artistic value, need to be fortified in order to elevate the operational performances of public culture and arts institutes.
