본 연구는 육아휴직제도가 출산에 미치는 정책효과에 대한 분석을 수행하였다. 육아휴직제도는 1차적으로 일과 가정의 양립을 취지로 하고 있다. 그러나 출산율 제고의 문제가 부각되면서 육아휴직제도 또한 출산장려책의 일환으로 기대되면서 육아휴직의 대상과 급여 혜택 또한 강화되어 왔다. 본 연구에서는 이러한 배경 하에서 복지패널 자료를 활용하여 가임기 여성 및 그 배우자의 육아휴직 혜택 이후 출산효과를 이중차분의 방법을 활용하여 분석하였다. 분석결과 육아휴직제도의 정책효과는 출산에 관한 한 아직까지 긍정적이지 않는 것으로 나타났다. 이러한 분석결과는 출산율 제고에 있어서 육아휴직제도의 실질적인 확대 외에 우리나라의 가정친화적인 노동환경 재정립의 필요성을 시사하고 있다.

본 연구는 Hofstede의 문화차원을 기준으로 온라인상에서의 문화적 차이를 사회 네트워크 분석을 통해 비교하는 것을 목적으로 한다. 이를 위해 동양 문화권에 속하는 한국과 영미 문화권에 속하는 미국, 영국의 온라인 커뮤니티에서 수집된 휴대폰 관련 구전 데이터를 활용하여 사회 네트워크 분석을 실시하였다. 분석결과 불확실성 회피성향을 반영하는 매개 중앙성을 제외한 모든 사회 네트워크 지표가 오프라인 상에서의 주장과 상반되는 결과를 보였다. 온라인상에서는 네트워크의 밀도와 연결 정도 중앙성, 위세 중앙성이 영미 문화권보다 한국에서 높게 나타나 한국이 영미 문화권보다 개인주의 성향이 강하고, 권력 거리가 작게 나타났다. 커뮤니케이션 속도 또한 한국보다 영미 문화권이 빠를 것으로 예상하였으나, 한국의 커뮤니케이션 속도가 영미 문화권에 비해 더 빠른 것으로 나타났다. 본 연구는 온라인상에서의 문화적 차이가 오프라인과 다르게 나타남을 발견하여 문화권에 대한 고정관념이 온라인 상에 그대로 적용되어서는 안 된다는 점을 확인함과 동시에, 온라인이 일탈의 공간으로써의 역할을 담당할 수 있음을 제시하였다. 또한 본 연구는 온라인상에서의 문화는 오프라인과는 다른 차원에서 접근할 필요가 있음을 확인하였다는 점에서 연구의 의의를 찾을 수 있을 것이다.

Epithelial-mesenchymal interaction plays a important role in cell growth and differentiation. This interaction is already well known to have an importance during the organ development as well as cell growth and differentiation. However, in vitro experimental model is not well developed to reproduce in vivo cellular microenvironment which provide a epithelial-mesenchymal interaction. Because conventional monolayer culture lacks epithelial-mensenchymal interaction, cultivated cells have an morphologic, biochemical, and functional characteristics differ from in vivo tissue. Moreover, it's condition is not able to induce cellular differention due to submerged culture condition. Therefore, the aims of this study were to develop and evaualte the in vitro experimental model that maintains epithelial-mesenchymal interaction by organotypic raft culture, and to characterize biologic properties of three-dimensionally reconstituted oral keratinocytes by histological and immunohistochemical analysis. The results were as follow; 1. Gingival keratinocytes reconstituted by three-dimensional organotypic culture revealed similar morphologic characteristics to biopsied patient specimen showing stratification, hyperkeratinosis, matutation of epithelial architecture. 2. Connective tissue structure was matured, and there is no difference during stratification period of epithelial 3-dimensional culture. 3. The longer of air-exposure culture on three-dimensionally reconstituted cells, the more epithelial maturation, increased epithelial thickness and surface keratinization 4. In reconstitued mucosa, the whole epidermis was positively stained by anti-involucrin antibody, and there is no difference according to air-exposured culture period. 5. The Hsp was expressed in the epithelial layer of three-dimensionally cultured cells, especially basal layer of epidermis. The change of Hsp expression was not significant by culture stratification. 6. Connexin 43, marker of cell-cell communication was revealed mild immunodeposition in reconstitued epithelium, and there is no significant expression change during stratification. These results suggest that three-dimensional oragnotypic co-culture of normal gingival keratinocytes with dermal equivalent consisting type I collagen and gingival fibroblasts results in similar morphologic and immunohistochemical characteristics to in vivo patient specimens. And this culture system seems to provide adequate micro-environment for in vitro tissue reconstitution. Therefore, further study will be focused to study of in vitro gingivitis model, development of novel perioodntal disease therapeutics and epithelial-mensenchymal interaction.

I studied about temperature and pH concentration having influence upon chlorophyll decrease on the Glucose culture of Chlorella variegata Beijerinck(211/10a). I cultured under $25^{\circ}C$(standard), $15^{\circ}C$ and $35^{\circ}C$ and compared with each other. The culture of $15^{\circ}C$ didn't have any large difference with the standard culture($25^{\circ}C$) but the culture of $35^{\circ}C$ had a large amount of chlorophyll decrease without carbohydrate accumulation, stimulation of cell division and nitrogen-deficiency. Chlorella variegata had optimum pH 6.5-7 and was a little weak in all phenomenon under pH 8 rather than under pH 6.5-7. Under pH 5 they had deep chlorophyll decrease without phephytin.

This paper considers the case study of the change management and business innovation of the rail construction agency fer overcoming the crisis it faced in early stage. It will provide the suitable innovation techniques of each change stage. Also, each phase it evaluated the change degree of organization culture especially by the six box model of Weisbord and the Quinn's model. For the Period of Change, organization culture will grow about 10% and harmonize with 4 competitive organization culture; community, innovation, hierarchy, product. Only, it discovered that the difference of the current culture and rho organizer' wish is considerable by the Quinn's model. It wilt be able to describe the innovation fatigue which the organizers feel in the change of organization culture. For the successful innovation, it wilt have to be managed properly and the new innovation technique will have to be developed for solving.
