Over the past decades, in vitro culture media have been developed to successfully support IVF embryo growth in a variety of species. Advanced reproductive technologies, such as somatic cell nuclear transfer (SCNT), challenge us with a new type of embryo, with special nutritional requirements and altered physiology under in vitro conditions. Numerous studies have successfully reconstructed cloned embryos of domestic animals for biomedical research and livestock production. However, studies evaluating suitable culture conditions for SCNT embryos in wildlife species are scarce (for both intra- and interspecies SCNT). Most of the existing studies derive from previous IVF work done in conventional domestic species. Extrapolation to non-domestic species presents significant challenges since we lack information on reproductive processes and embryo development in most wildlife species. Given the challenges in adapting culture media and conditions from IVF to SCNT embryos, developmental competence of SCNT embryos remains low. This review summarizes research efforts to tailor culture media to SCNT embryos and explore the different outcomes in diverse species. It will also consider how these culture media protocols have been extrapolated to wildlife species, most particularly using SCNT as a cutting-edge technical resource to assist in the preservation of endangered species.

The cold image of digital culture and its realistic limits force modern people to yearn for an emotional world characterized by a warm humanity. The kind of digital technology that appeals to such a human emotion is accepted as a new digital concept in the 21st century. The purpose of this study was to examine the characteristics of emotionality, which was a new trend in digital culture, and to discuss its form and meaning in fashion sector. It's basically meant to figure out a major trend in the 21st century's digital culture, to delve into its relationship with fashion reflecting sociocultural phenomena, and ultimately to describe in which direction future fashion would be led. Emotionality was highlighted as a reaction against an absolute pursuit of speed and cold digital technology. Emotionality of digital culture in fashion design were inserting of funology, Zen-based design and development of a clothing mixture. The emphasis of emotionality in digital culture is a new sociocultural trend that stresses the recovery of human nature. As futurologists predict that a human-centered and humanistic culture will reappear in the 21st century, fashion also will be in pursuit of human-oriented design.

The purpose of this study was to investigate the impact of organizational learning culture on job satisfaction and organizational commitment. Two streams of scholarly work have provided the theoretical foundations for this study. The first stream comes from the literature on learning organization. The second stream of the theoretical foundation comes from an extensive literature on attitude-intention-behavior relationships. In addition, this study was tested three alternative models. Alternative model 1 employed job satisfaction as the mediating commitments variable between learning culture and organizational commitment. Alternative model 2 used organizational commitment as the mediating variable between learning culture and job satisfaction. Finally, alternative model 3 specified a direct impact of learning culture on both job satisfaction and organizational commitment, and reciprocal linkages between these two variables. The results of this study support the hypothesized relations among an organization's learning culture, job satisfaction, and organizational commitment. The findings of this study are various congruent with a widely accepted hypothesis that job satisfaction serves as an appraisal function in evaluating various work environments and determining emotional responses such as organizational commitment. Organizational learning culture is one of the important factors that organizations cannot overlook. Therefore, the findings of this study provide a new direction for researchers seeking to explain the complex relations among these central organizational variables.

이 논문에서는 한국 과학기술정책의 시기별 특성과 전체적 특성을 검토하였다. 과학 기술정책의 발전단계는 형성기, 성장기, 전환기로 구분하였다. 한국에서는 과학기술의 진홍을 위한 제도적 기반이 공업화의 초기 단계부터 갖추어졌고, 1980년대 이후에는 정부연구개발사업이 전개되는 가운데 민간 부문의 기술혁신활동이 급속히 증가했으며, 1990년대 후반에는 과학기술정책에 대한 새로운 이념이 모색되면서 관련 법령 및 계획이 정비되기 시작하였다. 과학기술정책의 전체적 특성은 정책레짐이란 개념을 바탕으로 분석하였다. 지금까지 한국의 과학기술정책은 산업발전을 가장 중요한 정책목표로 삼아왔고, 정책수단의 측면에서는 외형적 투입요소가 증가하는 양상을 보였으며, 관료 중심의 정책문화가 지배적이어서 경제문화, 학문문화, 시민문화는 충분히 발전하지 못했다.

The purpose of this study is to investigate relations between the organizational culture and job satisfaction of ordinary dental technicians who are serving at dental laboratories. Findings of the study are summarized as follows. Ordinary dental technicians' job satisfaction as a whole was measured 3.40 in average score. In detail, those dental technicians were highest in satisfaction about their work, followed by their work conditions, organizational relations and occupation itself in order, but showed some dissatisfaction in terms of their self-realization. Regarding relations between the organizational culture and job satisfaction of ordinary dental technicians, the former was found significantly affecting the latter. Those dental technicians' job satisfaction was being most positively influenced by innovation-orientation as one of their organizational culture styles, followed by task-orientation. In regard to relations between sub-areas of the satisfaction and styles of the culture, ordinary dental technicians' organizational relations were being significantly, positively affected by such styles of their organizational culture as relation-orientation and task-orientation. Those technicians' occupational satisfaction, self-realization and work conditions were being strongly influenced by one of their organizational culture styles, that is, innovation-orientation. Originary dental technicians' work satisfaction was not being significantly affected by any of the organizational culture styles. The more relation- or task-orienting ordinary dental technicians were in organizational culture, the stronger their organizational relations were. The more innovation-orienting ordinary dental technicians were in organizational culture, the more those dental technicians' satisfaction regarding their occupation, self-realization and work conditions is likely to positively change. These findings indicate that ordinary dental technicians are even more orienting both relation and task in organizational culture, while being afraid of innovation and that their organizational culture as a whole is somewhat strict hierarchically.
