The purpose of this study examines interaction between region and industries through industrial networks of the regional resource-based industry. To achieve this goal, the fermented soy products industry in Sunchang is selected as a case study. This study traces the process of adjustment of firm-activity networks. And then, it scrutinizes the coevolution process between region and industry. It shows that the fermented soy products industry in Sunchang is embedded in the region and it strengthens regional development potentials for the local/regional economy.

The value chain is analytically useful for the cultural industry that has the characteristics of both manufacture and service industry, as the focus of value chain analysis moves from manufacturing only to the other stages of activity involved in supplying goods and services to consumers. The aim of paper is to analyse the value chain of the cultural industry in Gyeongbuk, find out the strengths and weaknesses of it, and suggest the ways to enhance the innovation capabilities of cultural industry in Gyeongbuk. First, the firms in advertisement & marketing, and circulation & distribution have low percent in cultural industry and need the low level of human resource, but produce high value-added in value chain; so, we should facilitate the make-up of the firms in advertisement & marketing, and circulation & distribution. Second, we should strengthen inter-firm networks to facilitate the ex-change of the equipment, human resource, information and technology between them. Third, we should construct the system to development human resource with two levels and spread the open atmosphere of firms.

The operation of high-speed rail (HSR) has an effect on the agglomeration economies, and the impact is shown as a relocation of individual firm and worker to where business activity can be maximized. The proximity to the HSR station could be considered as a core district to maximize the industrial benefit through the HSR network. From this perspective, this study considers the agglomeration effect of HSR within the HSR station-area and analyzed the agglomerated spatial pattern through hotspot analysis by service industry in the cases of Korea and Japan using GIS. This study analyzed the service industry within 1km distance from 8 HSR stations of Korea and 4 Kyushu Shinkansen stations of Japan. The results suggest that the hotspot patterns are observed in the service industry within 1km distance from the HSR station of Korea and Japan, except for two HSR stations of Gupo station and Kagoshima-Chuo station. Leisure, amusement, association, and other specific service industries could be affected by HSR passengers and knowledge-spillovers through HSR station. Therefore, the observed hotspot districts near the HSR station-area could explain an agglomeration pattern of the service industry through a closeness to the HSR station. Further, we could expect that the impact of HSR affects the service industry, and the impact could attract business activities of the service-area to maximize their benefit from HSR travelers. With the result, it is required to build up a supportive policy to maximize the HSR's impact on the service industry when considering the HSR station-area development.

The nuclear maturation and developmental competence of immature, oocytes collected from donors at various morphology of corpus luteum (CL) and fertilized in vitro was investigated by comparing the meiotic activity and the yields of embryos. Ovaries were divided and classified into 4 groups as the following criteria : Group 1 ; ovaries showed evidence of recent ovulation (corpus hemorragicum). Group 2 ; apex of CL was red or brown. Vasculization was limited to periphery of CL. Group 3 ; apex of CL was orange or tan. Vasculization was covered over apex of CL. Group 4 ; CL was light yellow to white and firm in texture and the vascular network on the surface of CL had disappeared. Modified TCM 199 was used for maturation in vitro of immature oocytes and development was induced by using TLP-PVA as a basic medium. When oocytes collected from each group of donors had been matured for 4, 14, and 24 hours in vitro, the proportion of oocytes reaching metaphase I and metaphase II were not different among oocytes from 4 group of ovaries. Mature metaphase II stage of oocytes in each group was first observed at 14 hours, whereas completion of maturation of. oocytes in each group was at 24 hours. Luteal morphology of ovaries had little effect on the proportion of embryos reached 2 cells and 8 cell stage. However, the proportion of embryos cleaved to morula and blastocyst stage was significantly higher in the oocytes obtained from group 1 and 3 than in the oocytes from group 2 and 4 (p＜0.05). This data suggest that reproductive status of the donor significantly influence the yield of in vitro embryos.
