The properties of a machine tool greatly affect machining quality since a machine tool has large variance in its features. Machine tool makers want to find best machining condition with the one that they have built. Machine builders need to develop test specimen since it helps finding characteristics of machine tools when the machining properties of the specimen are analyzed. This paper develops test specimen to identify features of the main spindle, the feeding device, and the frame of a machine tool. The specimen is machined with a high speed machine and the features of the machine are analyzed with test items. They are surface roughness, overshoot in axial movement, errors in circular movement, feeding with small movement, and compensational error. This work can improve usability for a machine tool in machining practice.

The purpose of this study is to investigate the sensibility of body exposure in contemporary fashion. 31 kinds of costume samples have been selected from photographs in fashion magazines. Those were divided into part of exposed body, the way of exposure and kinds of exposure. I have measured them by using Semantic Differential method. The subjects were 120 male and 120 female in twenties. The obtained data were analyzed by factor analysis, ANOVA, MDS and regression analysis. The results of analysis are as follow; 1. Factor analysis has extracted four factors which consist of the sensibility of body exposure. These factors are Attraction, Activity, Boldness, Simplicity. 2. There were significant differences in design of body exposure and demographics. 3. Evaluative dimensions of the sensibility of body exposure were identified by Hard-Soft, Active-Elegant. 4. Preference was related to words which are buying desirable, attractive, simple, natural, active appealed by design of body exposure costume and buying desirable was related to words which are favorite, modest, beautiful, natural appealed by mood of exposure costume.

The purpose of this study is to clarify the relationship between the visual sensibility and the decorative design of clothing. 41 kinds of costume samples have been selected from photographs in fashion magazines under detail and trimming, and divided into three types according to line, shape, and form. I have measured these images by using Semantic Differential method. The obtained data were analyzed by factor analysis ANOVA, discriminant analysis, regression analysis and MDS. The results of analysis are as follow; 1. Factor analysis has extracted five factors which consist of decorative design sensibility. These factors are Attractiveness, Hardness and Softness, Rhythm, Decorativeness, Cuteness. 2. There were significant differences in visual evaluation of decorative design and demographics 3. The discrimination among formative designs was closely related to decorative image, especially between line and form. 4. The Image effect on Preference, Buying needs, Riches and Pleasant was consist of complicated sensibility. 5. Evaluative dimensions of decorative design were identified by Simple-Complicated, Cubic -Plane perceptive image differed in degree of similarity in spite of same formative design.

An understanding of consumers' evaluative processes and the consumer variables that influence cross-cultural evaluations of foreign products is essential to effectively penetrate international markets. This study compared consumers in two developing countries, Korea and Mexico, regarding their product evaluations and purchase intentions for US Levi's jeans. Both Korean and Mexican consumers are generally quality and price conscious. Korean consumers appeared to be more value-conscious than Mexican consumers. Mexican consumers exhibited high level of brand and prestige conscious behavior. Findings in this study support that culture bound consumer characteristics vary from country to country resulting in differences in perception of quality, value and purchase intentions for a particular product. The perception of product quality differs from perception of value and subsequent willingness to buy. For a comprehensive understanding of consumer purchase behavior, the impact of value-conscious attitude on percetion of quality and on purchase intentions should be examined.

The purposes of the present study were (1) to examine the differences between the experienced group in buying foreign-brand formal wear and the non-experienced group in terms of demographic characteristics, clothing expenditures, and purchase behaviors of formal wear, and (2) to investigate the purchase behaviors of and the extent of post-purchase satisfaction to foreign-brand formal wears for purchase group of foreign-brand formal wear. By using questionnaire consisting of 20 questions, data were collected from 754 female consumers in age range of 20~59. Chi-square analysis and t-test were used for data analysis. Significant differences were found between the groups in educational levels, monthly clothing expenditures, monthly household income, the number of formal wear purchased per season, store patronage, items often purchased, perceived proper price per item, and criteria for selecting stores and evaluating products. The group with experiences in purchasing foreign-brand formal wear showed high satisfaction levels with the quality of foreign-brand formal wears. When buying foreign-brand formal wears, the experienced group considered styles and color as important evaluative criteria, and favored stores having sales with wide assortmetsn.

This paper presetns an adaptive critic self-learning control system with cerebellar model articulation controller (CMAC)-based decoder integrated with the associative search element (ASE) and adatpive critic element(ACE)- based scheme. The tast of the system is to balance a pole that is hinged to a movable cart by applying forces to the cart's base. The problem is that error feedback information is limited. This problem can be sloved when some adaptive control devices are involved. The ASE incorporates prediction information for reinforrcement from a critic to produce evaluative information for the plant. The CMAC-based decoder interprets one state to a set of patways into the ASE/ACE. These signals correspond to te current state and its possible preceding action states. The CMAC's information interpolation improves the learning speed. And design inverted pendulum hardware system to show control capability with neural network.
