This research investigated the purchasing behaviors of fur clothing consumers to verify fur clothing consumption and to establish marketing strategies for the fur clothing market. Since fur clothing has clear characteristics distinguishing it from other clothes, there are many differences in customers' interest. Therefore, it is needed to identify some differences in the customers' interest by their own buying habits. A survey was conducted with a questionnaire and revised by using a theoretical background. Questionnaires were given to 322 ladies in their over 20s. SPSS 12.0 was used to analyse the result with analysis of frequency, a primary factor, crossing, cluster and ANOVA. There were several results as follows. First, purchase behaviors of fur clothing were significantly different between groups divided by demographic variables such as marital status, age, and income level of household. Second, factor analysis on sought clothing benefits resulted in 4 dimensions such as symbolic value, brand value, economical value and practical value. Cluster analysis on the 4 factors of clothing benefits being sought resulted in 3 groups such as one group pursuing symbolism, one group pursuing practicism/economism and a group pursuing brand. Third, purchase behaviors of fur clothing and demographic variables were significantly different between the groups divided by clothing benefits being sought.

The purpose of this study is to look into the question-What kind of factors, among various influencing factors of temple architecture, change the development of villages with their its relationships to the temple. For the study, the villages located around a temple site with special geographic characteristics were chosen. It was analyzed and generalized what kind of social factors were chosen and applied to the design of residential buildings in those villages. The characteristics of the buildings in the villages that have relationships with the temple appeared to be as follows; Financial factor of the temple, rather than religious influences of it, appeared to influence strongly over the forms of building and the spaces of village. The village which formed along a new entrance axis to the temple were transformed to have a spatial organization along with added sightseeing and commercial functions. The villages have different spatial structures depending on their land uses. In short, the form of entrance axis to the temple has changed the economical dependence of villages on the temple, and becomes the major factor of transforming the spatial organization of the villages.

Although the round length for tunnel excavation has a major technical and economical impact in conventional tunnelling, there is no coherent procedure available for its determination. In this study, the influence of round length on the behaviour modes of weak rock tunnel was investigated by numerical analyses. Quantitative estimation of the behaviour modes of the face and the unsupported span was established by use of the safety factor for the face stability and the conditional chart. In addition, the optimum round length in the tunnel design stage was investigated based on the detail construction information such as cycle time and material costs. Although this proposed method has some restrictions, it is expected to provide useful information for the optimization of the tunnel excavation, especially in design stage.

This paper proposes an extension of the Improved Forced Based Design procedure to 3D steel structures. The Improved Forced Based Design (IFBD) procedure consists of a more rational sequence of the design checks proposed in Eurocode 8 and involves a more realistic selection of the behaviour factor instead of selecting an empirical value based on the ductility class and lateral resisting system adopted. The design procedure was tested on a group of four 3D steel structures, composed by moment-resisting frames with three storeys height and the same plan configuration in all storeys. The plan configuration was defined in order to target lateral restrained or unrestrained systems as well as plan regular or irregular structures. The same group of structures was also designed according to the force-based process prescribed in Eurocode 8. The member sizes obtained through the two approaches were compared and the seismic performance was assessed through nonlinear static and time-history analyses. The limit states referred to structural and non-structural damage, considering the two levels design approach, which are the serviceability and the ultimate limit states, were examined. The results obtained reveal that the IFBD leads to more economical structures that still comply with the performance requirements prescribed in Eurocode 8.
