ジャーナル フリーFrom the position of pattern making, we searched for the relation between plane development and 3D torso surface curvature by examining angle at concentrated vertices. This method will be referred to as the “Angle at vertex method”. The body forms of 110 young women were recorded with a 3D digitizer, and simulated by a triangulated polyhedron. Each concentrated Angle θ at the vertex was calculated for either internal Concentrated Gaussian Curvature (2π-θ), or boundary line Concentrated Geodesic Curvature (7π-θ). The total of Concentrated Sum of Gaussian Curvature and Geodesic Curvature for each model was -4π. A pattern of angular conservation was established, in accordance with Gauss-Bonnet theorem. On a macro level, we evaluated the distribution of curvature and general features of curvature for each model. On a micro level, we examined the regional characteristics in terms of sum positive values and sum negative values independently for both curvatures types, using the simulated Standard Model. The areas of the bust and shoulder will be difficult to construct from plan due to the positive and negative Gaussian Curvatures. Geodesic Curvature is concave around the neck-base line and armscye line, and the waist line is almost straight when translated to plan. The curvatures of every point on the Standard Model were color displayed, making it a highly informative tool for understanding the torso surface form.抄録全体を表示PDF形式でダウンロード (2251K) -

ジャーナル フリーSeasonal variation of sweating response to the thermal stimuli was investigated by the power spectral analysis. Both the summer and winter experiments were performed on the same subjects. The sweat rate was measured by using a sweat capsule, and was analyzed by the fast fourier transform. In the spectra obtained, the low frequency components for the summer were larger than for the winter, and each of the peaks in the power spectra for the summer was shifted to the higher frequency from the corresponding peak for the winter. This shows the adapted changes in the rhythm of thermoregulation to the heat acclimatization. As a result of the examination for the frequency distribution of the sweat rate, the frequency component at 0.02Hz for the summer was found to be larger than that for the winter. This component was significantly correlated to the blood flow, so it suggests that the seasonal variation of dynamic property in sweating activity is affected by the blood flow.抄録全体を表示PDF形式でダウンロード (427K) -

ジャーナル フリーWe propose a modeling method of a human body for dress simulation using computer graphics. The body is modeled by primitives called metaballs which are useful for representing smooth surfaces. The method proposed here has two phases: In the first phase, we generate a human body model by adjusting the input of the metaballs by hand based on measured data obtained by the range data. In the second phase, the standard human model is deformed to other size bodies based on the range data. That is, once a standard human model is generated, various body types can be easily obtained. In the previous work, approximation precision was not enough sufficient. Our method can generate a human body with a small degree of error by using the following procedures: 1) metaballs are roughly set on the cross sections obtained by data sliced from the range data; these cross sections are selected so that they include special features such as nipple and waist point, 2) the metaballs on each slice are optimized by using the Steep Decent Method, 3) After combining these metaballs on slices, total metaballs are optimized using the Steep Decent Method again. In order to demonstrate the effectiveness of the proposed method, we show two examples of metaball human bodies based on the range data; a standard body model and a fat body model are deformed from it.抄録全体を表示PDF形式でダウンロード (4898K) -

ジャーナル フリーWhen we wear gloves, they are a part of hands in movements, and must be an object of evaluation. Evaluation of gloves needs a new point of view, from “active touch and passive touch”, especialy in cold regions where gloves are used daily, and at the same time they must move easily with hands in winter. Gibson noted that active touch is an exploratory rather than a merely receptive sense. The vital of this paper is that there should be some differences between vision and touch in evaluation of gloves if objectivity is strengthened by vision. Two tests for the evaluation of gloves were conducted under two conditions, touch and touch-and-vision conditions. The combination of some of hand, glove, object and movement was the key element in both tests. From the sensory test, the difference between the factors that affect the total sense of glove was derived between conditions. Secondly, the test was carried out as to the hand working functions. The functions were compared between the lap time in the seven processes of works by hand with glove to the one by bare hands. The outcome of two tests showed that senses through touch and/or vision, forming total evaluation independently, influenced our hand movements in the daily life. We could evaluate the gloves more objectively with touch and vision than with only touch, when we worked on objects like a brief case or a glass. Touch made subjects sensitive to evaluate the inherent property of gloves like weight and compressional energy. Since it is possible to judge the mechanical properties of gloves being helped by visual memory, the lap time to achieve the movements were quite different between results in both condition tests.抄録全体を表示PDF形式でダウンロード (1201K) -

ジャーナル フリーA mechanism of moisture permeability through ten-layered knitted fabrics was investigated by the method used in the previous report (Mechanism of Moisture Permeation through Cellulose Fabrics). The composition of the fabrics was each of untreated wool, treated wool with the membrane of polymer being forned by the different methods of treatment on the surface of fiber, and the crimped acrylic fiber.
Based on the characteristics of the fiber and the use of knitted fabrics, contrary to woven fabrics, it was showed that the moisture permeability through knitted fabrics occured by a diffusion of water vapour in the minite space among fibers in the layered fabrics, and the diffusion coefficient Dc was calculated. The volume of a space per a unit surface of the fiber in a unit volume of the fabrics was calculated as a qualitative indication of the minute space. As the volume cited above is larger, the Dc is larger. And the highest value of Dc was coincided with the diffusion coefficient of water vapour in the air.抄録全体を表示PDF形式でダウンロード (604K) -
