This paper examined risk reduction methods utilized by consumers in apparel buying situation in multidimensional conceptual framework, and analyzed the relationships between risk types, consumer demographic variables and preferences of risk reduction methods. Samples of 224 consumers were deliberately selected to include various demographic characteristics such as sex, age, educational level, occupation, income level. The results of the principal axis factor analysis indicated that 26 item risk reduction methods could be summarized into 6 meaningful factors; Marketer-dominated Information Sources Use (MIS), Prepurchase Deliberation / Observation / Dependence on Past Buying Experience (DOE), Independent Information Sources Use (IIS), Interpersonal Information Sources Use (PIS), Brand Loyalty (BL), Label Reading / Guarantee Buying (RG). DOE were used most whereas IIS used least. Correlations of various types of risk perceived with the preference of risk reduction methods were significant especially for positive relationship between psychological and/or economic risk and DOE, and between social risk and/or fashionability loss and MIS. Results of ANOVA and Duncan test suggested that sex, age, educational level, occupation of consumers can act as ones of determinant variables on making differences in the use of risk reduction methods.

The purpose of this study is developing the new method of describing spatial configuration with considering degree of circulation quantitatively. That is named 'SCGC'(Spatial Configuration Graph of Circulation) in this thesis.The starting point of this study was reviewing 'the node-edge Graph'. The characters of SCGC are followings. At the first of all, SCGC is the method of spatial analysis and of spatial composition through quantification of moving circulation's connection. Secondly, SCGC is developed 'node-edge graph' which is based on 'node' of connection in unit space and 'edge' for capabilities of circulation elements. At the last, the SCGC can be showed correlations of 'unit spaces' about whole space which comes out from 'connectivity of connection line', 'connective control value', 'connective integration'.

The purpose of this study is to analyze the functional relations and proximity of facilities in commercial mixed-use buildings. This study particularly develops the evaluation method for functional relations and the proximity of facilities in terms of their location and circulation from user's perspective. By literature survey, the functional zones are defined. Questionnaire survey was conducted and analyzed to elicit the peoples' perception of the study area. Drawing analyses and user behavior observations allow us to develop evaluation system for the proximity of facilities. We carried out case study using the developed evaluation method.Research revealed following results. Many cases show that the functional relations and 'proximity' of facilities do not correspond each other. First, existing functional zone is needed strong functional relations although they have strong 'proximity' of facilities. Second, the 'popular-facilities' are needed stronger relations than the 'purpose-facilities'. Inversely, the 'purpose-facilities' have stronger proximity than 'popular-facilities'. Third, the public-zone(e.g. public plaza) is demanded high functional relation not just than 'proximity'.

In 2+1 dimensional nonrelativistic Chern-Simons gauge theories on S2 which has a global SU(M)symmetry, the semilocal Popov vortex equations are obtained as Bogomolny equations by minimizingthe energy in the presence of a uniform external magnetic field. We study the equations withmany flavors and find several families of exact solutions. The equations are transformed to thesemilocal Liouville equations for which some exact solutions are known. In this paper, we find newexact solutions of the semilocal Liouville equations. Using these solutions, we construct solutionsto the semilocal Popov equations. The solutions are expressed in terms of one or more arbitraryrational functions on S2. Some simple solutions reduce to CPM−1 lump configurations.
