  • The purpose of the study is to verify the effect of the Domus type on the modern housing-typology. This article specifies conceptual architectural typology through studying housing types and the changes by comparing experimental results over time since the ancient to the modern times. To successfully establish the purpose of this article, I cited Saussure's verbal methodology of system and representation along with Deleuze's philosophical cause of differentiation and repetition. Also adopting Aldo Rossi's architectural theory of typology, I established theory of housing continuation and alteration. I will compare and analyze particularly the Domus type, Adolf Loos's M$\ddot{u}$ller house, Luis Barragan's house, Le Corbusier's Villa Sovoye, and Mies van der Rohe's Three court house. And I research on the difference between architectural representation of hall and courtyard in modern housing. This research looks to emphasize historical comprehension and practical application of architectural history through housing studies.

  • In this study, thermal-hydrological-chemical modeling for the alteration of a bentonite buffer is carried out using a simulation code TOUGHREACT. The modeling results show that the water saturation of bentonite steadily increases and finally the bentonite is fully saturated after 10 years. In addition, the temperature rapidly increases and stabilizes after 0.5 year, exhibiting a constant thermal gradient as a function of distance from the copper tube. The change of thermal-hydrological conditions mainly results in the alteration of anhydrite and calcite. Anhydrite and calcite are dissolved along with the inflow of groundwater. They then tend to precipitate in the vicinity of the copper tube due to its high temperature. This behavior induces a slight decrease in porosity and permeability of bentonite near the copper tube. Furthermore, this study finds that the diffusion coefficient can significantly affect the alteration of anhydrite and calcite, which causes changes in the hydrological properties of bentonite such as porosity and permeability. This study may facilitate the safety assessment of high-level radioactive waste repositories.

  • The objectives of the study is to examine students concepts changes using a longitudinal study. The study compared two data sets collected in 1989 and in 1990 using the same instrument and subjects. The first data set was collected by Ahn(Ahn, 1989). In the study, students' patterns of misconceptions were examined in the following aspects : 1) Comparison of the students' misconception before observation of actual phenomenon in the first data between the two data sets. 2) The analysis of the patterns of students misconceptions of the second data set In terms of students' patterns of conceptual change before and after observation in the first data set. In the study, overall patterns of students' misconceptions appeared in the second data set were similar to those of the first data set ; however, about 40% of individual student's patterns of misconceptions were changed. Even the students who changed their opinion from misconception to scientific by observing the give phenomenon in the previous study(the first data set) returned to their original misconception after one year. The researcher interpreted this phenomenon in terms of the characteristics of the three kinds of cognitive conflict suggested by Kwon(Kwon, 1989).

  • One of the major activities in scientific inquiry, as well as in the process of conceptual change, is the generation of scientific hypothesis. In this study, the definition and the characteristics of scientific hypothesis are analyzed. Especially, differences between explanatory hypothesis and scientific explanation, predictive hypothesis and scientific prediction, and scientific hypothesis and the inductive generalization are analyzed. And the process of making scientific hypothesis is suggested as 4 stages, and the role and the characteristic of the abductive thinking, which can be viewed as one of the scientific inferences needed to generate hypothesis, are discussed. In analysis, concrete examples from integrated science textbook of high school are used for application to the classroom teaching.

  • The purpose of this study was to analyze changes in perceptions of the categories of environmental education and environmental education professionalism of teachers participating in a in-service teacher training programs for environmental education. For this study, surveys and interviews were conducted before and after participation of 20 elementary and secondary school teachers who had participated in 'in-service teacher training program for professional development in environmental education' in August of 2005. Before participation, most of teachers answered that 'Education for Environment' was essential factor among the categories for environmental education. After participation, 15 teachers retained their perception but 5 teachers had changed to 'Education about Environment' or 'Education for Environment'. Environmental professionalism was conducted in '5 ability categories of environment teachers' of Hungerford et al.(1994). Categories has goal domains such as 'Goal domain I (level of basic)', 'Goal domain II (level of conceptual perceptions)', 'Goal domain III (level of investigating and evaluation)', 'Goal domain IV(level of environmental action skill)', 'Goal domain V(level of educational apply)'. Before participation, teachers had a low level of professionalism in environmental areas, but after participation environmental education professionalism improved significantly into the all 'Goal domains'.

  • The growth in services has focused issues of service quality both for commercial enterprises and across a range of public services and government institutions. The education sector, in particular, has undergone radical change to meet the needs of its varied constituents. This paper examines key issues in internal service, customer satisfaction, service quality, relational commitment as they apply in one particular education sector. The purpose of this study is to analyze effect of internal service on customer satisfaction, educational service quality. First, In the dimension of internal service, many factors affect internal customer's evaluation for overall satisfaction. They are categorized as five factors; tangibles, reliability, responsiveness, assurance, empathy. The results of this study supported the proposed conceptual framework overall. Therefore, we identified that internal service quality is the antecedent of an internal customer satisfaction, and the consequent variables of an internal customer satisfaction are educational service quality, external customer satisfaction. The major findings of this study are summarized as follows. First, some factors(tangibles, reliability, responsiveness, assurance, empathy) affected positively internal customer satisfaction. Second, external service quality affected positively educational service quality, external satisfaction. In other words, the more internal customers have experienced internal service, the higher internal service quality deliver educational service quality.

  • Prior research has reported that student epistemological beliefs might affect their participation in learning and the process of conceptual change. The purposes of this study were to investigate the characteristics of sixth grade students epistemological beliefs about science and the relation between their epistemological beliefs about science and factors related their learning. For this research questions, 245 sixth grade students participated and various test instruments were used in this study. Students answered two types of questionnaires on epistemological beliefs about science and three test instruments on factors related students' learning(achievement in science, science inquiry skills, and cognitive levels). The results of this study were as follows. First, a large number of elementary school students believed that the purpose of science to perform activities like simple experiments. A lot of students believed that scientific knowledge was changeable according to the nature of scientific knowledge and that scientific knowledge could be learnt on their own. Also, many students believed experiment results to be basis on which to form personal scientific conceptions. Second, students who believed in more modern epistemology about science represented higher levels of science learning achievement, science inquiry skills, and cognitive levels. Therefore, when developing science curriculum, science educators need to consider how to develop student modern epistemological beliefs about science.

  • The purpose of this study is to define the concept of community based on the residential area and to review the issues on the research of community in related discipline area. The discourse about community has been developed in the field of social psychology, regional planning and architecture, housing studies, and research results by NGO. These studies of community has been dealt with social interaction and norm as well as the physical aspects of community. The research on community has been studied with the approach of structure and functionalist, systems theory approach, conflict theory approach, ecological approach, microsociological approach, and social construction approach. However, these approaches have not integrated together, but recognized community in a social or personal context. The social construction approach among these approaches suggest a useful conceptual framework for studying community in the point of view that social condition changes according to the autonomic individual. Understanding of community will influence to establishing a community norm, to planning a communal space, and to developing strategies of community. And it also takes a Important role t\ulcorner change the housing policy, institution and life style.

  • This study empirically investigates whether urbanization triggers urban disaster damages in the metropolitan areas of Korea by applying panel data analysis. Issues are approached with respect to the perspective that increased natural disaster damages are closely related with urbanization. This paper describes the conceptual framework of disaster management to understand the factors that determine urban disaster damages in Korea. This study used a simplified model with some key factors for analysis, because flood damage factors in urban areas are too diverse, and a full understanding of every cause is not feasible. The results indicate that urbanization does not necessarily lead to increasing urban disaster damages and if properly managed, urbanization can actually reduce urban disaster damage.
