Since the middle of 80's, foodservice industry has steadily developed, as the national income has been increased in correspondence with economic growth. We can figure that the improvement of culture life such as the improvement of culture life such as the conspicuous trend forward nuclear families, increasing double income family and the rate of holding car, has had something close to do with development of foodservice industry in the such economic development. Therefore, this study is to analyze foodservice industry playing an important role in the culture life and the influence of culture life improvement to foodservice industry, directly or indirectly, in accordance with the brilliant economic development in Korea.

The developmental regulation of the preimplantation mammalian embryos is a fundamental step for preparing the implantation and it may be regulated by several autocrine and paracrine factors including platelet-activating factor. PAF improved the embryonic survival and implantation but its role during blastocyst development is still largely unknown. In this study, the effects and the possible pathway of PAF on developmental regulation of blastocyst to hatching stage were investigated. Developmental pattern in hatching embryo was a concentration-response curve showing maximal activity at 1 nM PAF, with decreasing activity at higher concentrations. $50{\mu}M$ 1-(5-isoquinolimnesulfonyl)-2-methylpiperazinme dihydrochloride (H-7), a PKC inhibitor, inhibited the progression of blastocyst to hatching embryo. In addition H-7 blocked the PAF effects on the blastocyst development. Besides tetradecanoylphorbol acetate (TPA), a PKC activator stimulated development of blastocyst to the hatching stage. These finding revealed that PAF support the blastocyst development to the hatching embryo. Also it is suggested that PAF action pathways in hatching supporting include the PKC signaling pathway.

Competitiveness strategies has been associated in the tourism literature as a crucial factor for the success of tourist. The study aims to explore the competitiveness strategies for tourism destinations by conducting in-depth interviews with probe questions. Thirteen community enterprises' managers in rural tourism communities were interviewed with a semi-structured interview questionnaire for one or two hours. From the interview data, eight themes in two dimensions were identified as competitiveness strategies of rural community enterprises in rural Korea. Differentiation strategies consist of new product development, service improvement, brand image improvement, advertise and public relation, and concentration. Cost leadership dimension includes cost reduction, increasing benefit, and long-term investment. The findings of this paper implicate the underlying the competitiveness strategies from managers' perspective.

The purpose of this study was to explore relationships among technology development strategy, marketing competence, knowledge management competence, and company performance of textile and clothing companies. Survey data collected from 187 employees in the textile and clothing companies were analyzed by descriptive statistics, factor analysis, reliability analysis, correlation analysis, and multiple regression analysis. In results, certain levels of correlations were found among technological development strategy, marketing competence, knowledge management competence, and company performance. Specifically, technological gap which was one of the technology development strategy factors was a variable significantly affecting innovation performance and financial performance of textile and clothing companies. Knowledge management competence affected innovation performance whereas marketing competence affected financial competence of textile and clothing companies.

In this study, factors affecting the development of new products and research about the relevance of the factors based on the research model was configured. Existing research and technology commercialization process of discrimination that occur in the importance of risk management and open innovation company's competitive advantage in new product development and affect the reporter know what the effect is used as a control variable effects. Factor in the development of new products through research and innovation capacity and knowledge management activities, the introduction of open innovation and enterprise level ever due to the level of risk management controls and the need for effective research to study the model was proposed.

The purpose of this study was to analyze vocational competencies of rural youths. The study was carried out by focus group interview and questionnaire. The data were collected from 200 rural youths by stratified random sampling. The SPSSWIN / ver13 was used for analyzing data with t-test, ANOVA, and factor analysis. The major findings of this study were as follows; Firstly, rural youths showed higher competencies in handling and fixing machines, selecting seeds, where as rural youths showed lower competencies in goal setting, envisioning, acquiring agricultural policy information, management evaluation. Secondly, rural youths predicted optimistic future of their own farming even though the future of national farming should get smaller. Lastly, rural youths who are higher education, extending farming size, establishing farm had higher vocational competencies than other youths. Conclusionally, the study suggests adult-farmers give rural youths an opportunity to participate in decision making and farming.

This study examined the effects of growth factors in TCM199 on bovine 1-cell embryos development in vitro. After 6 day to 11 day in culture, 15.8%(19/120), 15.3%(20/130), 21.8%(35/160), 27.0%(56/207), 26.3%(53/201) and 30.7%(40/130) of the 1-cell embryos developed into expanding blastocysts in su, pp.ementing TCM199 with control, insulin, IGF-I, IGF-II, FGF and EGF, respectively. Hatching rate of 1-cell embryos in su, pp.ementing TCM199 with FGF, EGF and IGF-II were 21.4%(53/247), 20.3%(42/206) and 16.8%(41/243), respectively. The beneficial effect of growth factors on embryo development in vitro could be duplicated. These data indicate that the presence of FGF, EGF or IGF-II in the culture medium is beneficial for embryo development in vitro and accelerate cell differentiation.

This study explores the development processes of organic farmers' groups that have tried to manage farming activities at the regional level. They formed the groups from different reasons and situation each other. The motives to set up the groups differ between them. Some set up for the local farmers movement, others aim to get more income from the group activities. Whatever the motives, they all have been succeeded in the agricultural sector. Many new-born farmer's groups in organic farming sector tend to be regarded them as the models for success. Therefore, it is important to clarify how they have overcome difficult situation that may differ from group to group. This study tries to find and compare the four organic farmers groups with the factors of the historical processes for establishment, the process of business development, and the development of networks.

Early environmental exposure is recognized as a key factor for long-term health based on the Developmental Origins of Health and Disease hypothesis. It considers that early-life nutrition is now being recognized as a major contributor that may permanently program change of organ structure and function toward the development of diseases, in which epigenetic mechanisms are involved. Recent researches indicate early-life environmental factors modulate the microbiome development and the microbiome might be mediate diet-epigenetic interaction. This review aims to define which nutrients involve microbiome development during the critical window of susceptibility to disease, and how microbiome modulation regulates epigenetic changes and influences human health and future prevention strategies.

There have been few attempts made to perform a systematic analysis of the various risk influence factors in building development projects. This study suggests an analysis of the risk influence factors in the process of feasibility studies for apartment building development projects. To reflect the voice of professionals, surveys were carried out. In addition, an FD-AHP method was applied to identify the importance of the risk influence factors. Through the surveys, major risk factors were separately identified as direct and/or indirect elements. An analysis of risk influence factors supports an effective feasibility study of apartment building development projects.
