This experiment was intended to obtain a prefect casting body the same as the original wax patterns by melting metal into the opening of the ring. The investment ring was dried to the temperature between 600 and 700, when the wax pattern would be completely melted to leave an empty mould made in the ring. The main point to studied was the investing process for perfect casting body. This process was experimented on several important factors: the size and spatulation of investment particles, purity of wax patterns, investing time after the completion of model, and investing temperature. The results obtained from the above experiment were as follows: A desirable cast body with no fissure or pore would be mode by investing with smaller particles in the first time and with larger onces in the second, both at the temperature between 180.

This paper describes parameter identification techniques formulated for the estimation of maneuvering coefficients of a submerged body. The first part of this paper is concerned with the identifiability of the system parameters. The relationship between a stochastic linear time-invariant system and the equivalent dynamic system is investigated. The second is concerned with the development of the numerically stable identification technique. Two identification techniques are tested; one is the ma7mum likelihood (ML) methods using the Holder & Mead simplex search method and using the modified Newton-Raphson method, and the other is the modified extended Kalman filter (MEKF) method with a square-root algorithm, which can improve the numerical accuracy of the extended Kalman filter. As a results, it is said that the equations of motion for a submerged body have higher probability to generate simultaneous drift phenomenon compared to general state equations and only the ML method using the Holder & Mead simplex search method and the MEKF method with a square-root algorithm gives acceptable results.

The purpose of this study is to identify the expression methods of uncanny images shown in contemporary fashion through the visual expression methods of plastic arts. The study results are as following. First, there is a concept-forming element of 'The return of Repressed', which is a psychological mechanism for generating uncanny sets to the component of 'repression' and 'return'. 'Repression' herein consisted of 'unconsciousness', 'the other', and 'anxiety', while the return was composed of 'trauma' and 'repetition compulsion'. Second, there are visual expression methods of the uncanny in contemporary art. The subject of 'repressed things' was expressed as grotesque and having a terrible look. 'Fragmented body' was analyzed as 'dismantling' by mutilation, 'combination' placing cut body parts in other places, and 'damage' suffering from an illness or accident. 'Fear of death' was shown as 'anatomy' reminiscent of death and 'iconography of death' meaning return of the dead. 'Post-human' was a surrealistic being such as a monster and mechanized human, and was analyzed as 'gene variation' and 'cyborg'. Third, the methods of visual expression of the uncanny reflected on contemporary fashion was analyzed as 'fragmented body', 'fear of death', and 'post-human'. 'Fragmented body' appeared as the object reminiscent of the fragmented body, 'dismantling and combination of the body', and 'damage of the body' through the distortion of the clothing construction principle. 'Fear of death' visualized the characteristic elements of the subject reminiscent of death as 'iconography of death' and 'symbolic object of death' through the motif. 'Post-human' was the description of the subject beyond the body's function and form, and was shown as 'gene variation' and 'cyborg'.

The purpose of this study was to investigate the contributions of body joints to the kinetic energy of the clubhead in the golf swing. Three dimensional swing analysis was conducted on the seven KPGA golfers. The subjects were asked to swing with 45 inches of driver. The work done by body joints were computed by utilizing the inverse dynamics method. The order of work done by the body joints was lumbar > left hip > right shoulder > left wrist > right wrist > right hip at the first phase. At the second phase, the order of work done by the body joints was trunk > left elbow > right wrist > right shoulder > left wrist > right wrist. At the third phase, the order of work done by body joints was lumbar > right shoulder > left shoulder > left elbow > right wrist > right elbow. The sum of the work done by the body joints was lumbar > shoulder > wrist on the average. The kinetic energy of the club head was 430.11${\pm}$24.35 J and the subject's swing efficiency was shown as 31.82${\pm}$4.86% on the average. The contributions of body joints to the kinetic energy of the clubhead was the order of lumbar > upper right shoulder > left elbow > right wrist during the down swing.

Fashion have been expressed by a face through various a period, social change, and various culture changing. Human expresses as "Transformation" by applying these needs of changing to the fashion. A origin tribe expressed its own self by using direct body transformation and extreme decorations in the past. However, human express creative and esthetic desire based on shape, material, and transformation method in the present time characteristics of the body. Exceptional transformation breaking a existing fixed idea appeared frequently due to dissolution through transformation which is positive expression method in the fashion from 20th century. As a results, followings are obtained in this study. First, human body transforms by using a tool or intermediation in investigation of aesthetic meaning for human body. The object, Transformation, is stably transformed by disintegration, distortion, exaggeration and simplification reduction, as design's sensitivity. Second, transformation from relation of clothing composition is expressed by extension, reduction, simplification, and dissolution. In transformation from original tribe's sensitivity, past decorative desire lead to transformation of human body. To give variable change from past to present fashion, external formative will is introduced. Then, extreme expression is made by direct transformation of clothing type. It seems to be accomplished that human body's expression method is continuously changed into extension, exaggeration, reduction, and dissolution from transformation method as described before. Transformation of modem fashion is expression method by creative supervision. Extreme transformation substituted body's each part is based on immanent play and representative satisfaction. Through these transformation, it is judged that variety of creative type is achieved.

The present study was conducted to evaluate heterosis effects of body weight and jumping height for successive generations of rotational crossing using two subspecies of mice which are very different in body weight and in genetic relationship from each other. Domesticated laboratory mouse $CF_{{\sharp}1}$ (C) and Yonakuni wild mouse (Y) were used as materials. Two groups of rotational crossing was made according to the parent used at the beginning of crosses, C male$\times$Y female and Y male$\times$C female. These crosses were done to produce the first ($G_1$ and $G_1{^{\prime}}$), second ($G_2$ and $G_2{^{\prime}}$) and third generations ($G_3$ and $G_3{^{\prime}}$) with sire used was alternated. Individual body weights were weighed at 1 (wk1), 3 (wk3), 6 (wk6) and 10 weeks of age (wk10) and jumping heights were measured at six weeks of age (wk6). Only the first litter used. For body weight, results of this study showed that genetic group effects were significant (p<0.01) source of variation at all ages studied. Sex effects were significant (p<0.01) at wk3, wk6 and wk10, but not at wk1. Significant interaction effects (p<0.01) between genetic group and sex were found at wk6 and wk10. The C mice with large maternal effects produced heavier offspring body weight and crosses using sire of this subspecies maintained heavy weight compared to wild Y mouse sire that has small body size. Heterosis tended to exist at the rotational crossing started from Y male C female. For jumping height, effects of genetic group and sex were significant, sire and dam effects (heterosis) exhibited from the first to third generations, and no maternal effects were observed.
