Current criticism regarding the "uniformity" of Korean apartments has shown not only tendencies of emotional and unscholarly criticism, but also lack of academic discourse. They tend to stay at the common-sense level and be quite subjective without supporting facts. This research began with questioning the phenomenon of seeing Korean apartments as an object of negative criticism. The research questions for this study are: 1. Of the living space of so-called apartment houses, what elements should be called uniform?; 2. How should the implications of the findings be interpreted? In this context, this study aims to reinterpret criticisms on the uniformity of apartments from a new point of view. First, literature review is done to examine characteristics of Korean apartments in the social-cultural, economic, and physical contexts. Next, existing non-academic, abstract criticisms are classified into three trends, to show that the way of understanding architectural spaces by those criticisms are limited and weighted towards visual perceptions focused only on the shape of architectural structures. Finally, it is argued that the viewpoints of space and residents' experience should be treated as important for the reinterpretation of criticisms on the uniformity. This is validated through presenting relevant cases such as changes of space uses, diversified lifestyles being accepted, and the expansion of living space.

Various aspects of structural optimization techniques under transient loads are extensively reviewed. The main themes of the paper are treatment of time dependent constraints, calculation of design sensitivity, and approximation. Each subject is reviewed with the corresponding papers that have been published since 1970s. The treatment of time dependent constraints in both the direct method and the transformation method is discussed. Two ways of calculating design sensitivity of a structure under transient loads are discussed - direct differentiation method and adjoint variable method. The approximation concept mainly focuses on re- sponse surface method in crashworthiness and local approximation with the intermediate variable Especially, as an approximated optimization technique, Equivalent Static Load method which takes advantage of the well-established static response optimization technique is introduced. And as an application area of dynamic response optimization technique, the structural optimization in flexible multibody dynamic systems is re- viewed in the viewpoint of the above three themes

lonophores, uniquely, create specific pathways of ion permeability in model and cell membranes. Calcium-transporting ionophores of microbiological origin, such as A23187 and ionomycin, have been used as experimental tools to elucidate the physiological role of calcium as a second messenger in many cell types. These ionophores are believed to bypass the initial ligand-receptor step in the activation of cells by increasing membrane permeability to calcium. In this report, we shall discuss several naturally occurring substances that share some properties of calcium-ionophores, primarily concentrating on oxidized fatty acids. We have previously demonstrated that oxidized linoteic and arachidonic acids, obtained either by lipoxygenase catalysis or nonenzymatic processes, significantly promote calcium translocation in a two-phase partition model and modulate calcium-transporting function in the isolated sarcoplasmic reticulum vesicles obtained from mammalian hearts. We have also confirmed that calcium-ionophoric properties are due not to their general amphiphilic nature of certain lipids, but to distinct structural characteristics. Although there are some skeptical views on the occurrence of ionophores in higher organisms, increasing evidence suggests that membrane lipids or their derivatives may serve as physiological calcium-ionophores. Abnormal accumulation of lipid peroxidation products(particularly end products), however, may be associated with the general oxidative damages as seen in many pathological conditions.

Past research linking information technology and organizational structure has been inconclusive and contradictory. The purpose of this study is to resolve some of this confusion by taking into consideration one theoretical issue and three methodological problems. The one theoretical issue is an assessment of the importance of environment as a key external variable constraining both organizational structure and the use of information technology. To date, there has been no systematic, empirical research on the conceptual linkage among all three of these variables. The three methodological issues concern measurement problems associated with (1) controlling for different levels of analysis, (2) establishing a clear operationalization of information technology, and (3) differentiating institutional and questionnaire approaches to data collection. The research results in four conclusions. First, data confirm the environment as a key external variable in the linkage between information technology and organizational structure. Second, three central dimensions of information technology are identified: Growth of Capacity, extensiveness of information technology use, and information technology sophistication. Third, in order to maximize the explanatory power of information technology on other organizational constructs, it is necessary to differentiate between the actual use of information technology as opposed to the mere presence of information technology. Fourth, carefully designed questionnaire measures reveal no significant differences from institutional measures in the assessment of key organizational constructs.

Through reinvestigations of early years of King Young-Joe provincial castles, Jeonju Eupsung, this study seeks to broaden the understanding of castle construction of the later period of Chosun Dynasty. Jeonju Eupsung was established by reform-minded king and his loyalist Cho, Hyun Myung. Their new conceptual framework for reconstruction of Jeonju Eupsung was affected by Yoo, Hyung Won, a realist scholar of 17th century. It is obvious that adopted new administrative systems of financing, building and maintaining of Jeonju Eupsung were based on the his theories of castle. This study demonstrates that Jeonju Eupsung built by Cho, Hyun Myung, during the early years of King Young-Joe were based on those new concepts and systems of the new age. The study shows that the designer of this castle had in mind efficient construction design and execution and effective defense of provincial towns located on flat ground. And, the study explains how those original designer sought higher productivity through greater localization of securing resources and more detailed and improved organization of construction responsibilities. In short, this study seeks to prove that the provincial castles of the early 18th century reflected the new thinking on practicality that was spreading throughout the society of Chosun Dynasty at the time.

Gender equality has been expected to realize fully in the process of globalization. According to neo-liberal, which views globalization as a rational development, irrational discrimination by culture will disappear. But some feminists criticize globalization as a patriarchal phenomenon. So in this paper, the extent to which women in Korea have achieved equality with men in the workforce is assessed through an examination of the gender gap during 1993-2003. As the result, it was found that women had still lower status than men in spite of laws established to promote gender equality. Then to explore the direction for eliminating the patriarchal gaps, women in traditional Korea were reviewed. Traditionally women were oppressed by the practice of Naeoe differentiating between women and men. But on the other hand it made women to have equal status with men by maintaining their own productive area. So it was suggested that differentiation should be considered as a source of power to be adopted into women's activitism such as NGOs or international women' movement to achieve full equality in inequitable globalization.

This study aims to reinterpret Jeonggwanheon(靜觀軒) in terms of its use and architectural style after restoration work through the recently discovered [Deoksugung Palace's original plan](1915). It is presupposed that the existing interpretation of Jeonggwanheon, such as its status as the banquet hall of the Imperial Empire and the place where Emperor Gojong enjoyed coffee here, was a fantasy made from the transformation after the 1930s. When it was built around 1900, Jeonggwanheon arranged small and large rooms around the corridor in the center, and the porch surrounded the three sides of the building. From 1900 to 1907, there is no remaining record telling us who did what or when something happened in Jeonggwanheon except for several portraits of Emperor Gojong and his son which were drawn in 1902. The mixed use of brickwork and wooden porch are found in many of American style houses built in Incheon and Seoul at that time. Especially, the style and decoration of wooden porch seem to be influenced by Queen Anne style in the 19th century in America.

본 연구는 방송 통신 서비스의 경품 및 요금 감면 행위의 위법성 판단 기준과 규제 기관의 위법 행위 적발 및 시정조치 등을 분석함으로써 규제의 실효성 여부를 알아보고 효과적 규제 방안을 제안하고자 하는 연구목적을 지니고 있다. 연구 결과, 최근 들어 이용자에게 제공되는 경품과 요금 감면액의 차이가 급속히 증가하고 있음을 알 수 있었다. 또한 공정거래위원회는 부당성 판단 기준을 비용 이하로 요금을 책정하는 경우에만 부당염매로 판단하고 있지만 방송통신위원회는 '가입자 1인당 평균 예상이익'으로 적용하고 있는데, 모든 사업자의 평균값을 기준으로 함으로써 기업이 제공하는 서비스품질의 차이나 선발기업과 후발기업 간 비용 구조 차이를 고려하지 않아 후발 기업의 마케팅 비용을 상대적으로 높게 허용해주는 결과를 낳고 있다. 이용자 차별금지를 통해 후발 기업의 가입자 증가와 영업이익의 증가를 지원하는 결과를 가져오지만, 이는 직접적인 규제 목적이 아니며 적극적으로 정보를 추구하는 정보이용자의 후생이 감소하는 결과가 나타나고 있어 부당성 판단 기준에 대한 재고찰이 필요함을 제안하였다.
