    Because a paper pattern has two dimensions, it is easier to handle than a three-dimensional object. In contrast,it is difficult to assume the three-dimensional shape of a garment based on a paper pattern alone. Its shape must be confirmed by manufacturing a sample or by simulating the garment. In this paper, we propose a method using a Gaussian sphere to visualize “Gaussian curvature” and “meancurvature,“ which are geometric quantities of a three-dimensional shape. Angular defects,i.e., the Gaussian curvature of a polyhedron, are visualized as areas on the Gaussian sphere. This visualization relates to “conversion to the area of the Gaussian curvature“ directly, and provides information on the mean curvature of the Gaussian sphere. In addition, the examples are shown of the basic paper pattern and development charts of the polyhedron, polyhedral model, and Gaussian spheres.

    The purpose of this study is to investigate the relationship between the attitude in dressing behavior and the degree of interest to a sense of season. 306 women college students replied to the questionnaire concerning to the sense of season in daily life, the adaptability to season of clothes' types and the attitude in dressing behavior. These questionnaire data were analyzed by using statistical testing, cluster analysis and factor analysis. They wear upper garment properly by the season, but wear bottoms all the year round. Respondents were divided into high and low groups by the degree of interest to a sense of season. A tendency was recognized that the high group attaches importance to the dressing attitude with the low group. There were statistically significant differences between the high and low groups' factor score in factors of “trend”, “sense of season” and “self-expression”. It was recognized that there was relation between the dressing attitude and the degree of interest to a sense of season.

    There are many clothes that apply pressure and adhere to the body, such as girdles and spats. An attempt has been made to investigate the relationship between a pressure sensation and a comfortable sensation by applying various pressures on the human body. The experiment was carried out under the following conditions: seven women subjects, seven pressure body regions, ten pressurization levels, three widths of a pressure band, and standing posture. Maximum pressure level for the body is 4kPa. The body regions showing different pressure sensitivity for the different widths of a pressure band are chest, abdomen, hips, forearm, and thighs, even though the pressurization values are the same. In these body regions, if a width of a pressure band is wide, the pressure sensitivity is high. The pressure sensation is different by body region, even if they are the same pressurization value. The body regions of high pressure sensation are upper arm, chest, abdomen, and thighs, and the body regions of low pressure sensation are legs, forearm, hips, and thighs. In relation to pressure sensation and comfortable sensation, even though the pressure sensation and tight feeling is high, comfortable sensation is not high, at hips, legs, and forearm. On the other hand, if pressure sensation and tight feeling is high, it is easily felt uncomfortable, at chest, abdomen, and upper arm. In other words, it was clarified that it is necessary to pay attention to the diffence of pressure body region for not only pressure sensation but also comfortable sensation to design the clothing to feel comfortable with the clothing pressure.
