  • This study aims to apply the formative aesthetic of human body to the form of clothing. For this purpose I try to find the various methods of analysis used in the work of sculpture. The method of inference and the checklists of design are used to relate the sculpture with the clothing design specifically. This methodology intends to regard human body as an artistic form and use the image of sculpture to the maximum. Especially I try to derive the motives of design and recreate them in clothing design emphasizing silhouette. On this methodology, following results were developed. First, the observations on the formative characteristic of human body show that the transformed form of human body expresses more perfect image of human body than the original form. The power of simplicity heightens the total beauty of the work. Second, the image of human body expressed in simplicity heightens the total beauty of the work. Second, the image of human body expressed in simplicity and exaggeration can be variously recreated in a silhouette with the formative and cubic effect, simplicity, and activity. Third, the elegant and static image found in the analysis and synthesis of human body can be used as a motive of clothing design and the changed details lead to the transformation of silhouette. Fourth, in developing designs by the item of checklists, one motive can be variously recreated according to the methods of designs.

  • The gas leak and explosion accident is able to give a fatal injury to nearby people from the explosion center and interest in effect of the explosion on the human body is increased. Accidents by Portable Butane Gas Range of a gas explosion accident occupy the most share. As a result, the injury on the human body frequently occur. However, It is situation that are experiencing difficulties in consequence analysis of explosion accidents owing to shortage of explosion power data and lack of research on the effect of the human body by the gas explosion. This paper acquire human injury data by performing the actual explosion experiment with Portable Butane Gas Range and evaluate power by explosion and effect of explosion on the human body to perform explosion simulation with LS-DYNA program. It is intended to contribute to the exact cause of the accident investigation and the same type of accident prevention.

  • Electromagnetic fields, radiated from an intestine-ingested source and propagated through an inhomogeneous human body model, are computed with the finite-difference time-domain (FDTD) method. The calculated results obtained at some receiving points vertically placed according to the abdomen of the human body model show unusual dip patterns in the frequency domain. The frequency of this unusual dip varies according to the location of the receiving points. Thus, the relationship between the frequency of the unusual dip and the incident angle of the line-of-sight is analyzed. The effect of the location of an ingested source on the above relationship is also investigated. The slope of the approximately linear relationship is affected by the location of the ingested source.

  • This paper investigates the effect of absorption loss by a human body to the received signal strength with respect to on-body transmitting antenna positions in on-to-off wireless body area networks. This investigation is based on measurement results obtained from experiments performed on human bodies (male and female) using planar inverted-F antennas in an anechoic chamber. The total absorption loss by the human body is also presented through the SEMCAD-X simulations. Our investigation showed that the received signal strength becomes lower when the transmitting antenna is mounted at a specific position where more absorption loss is experienced. The statistical analyses of on-to-off body channel characteristics based on the measurement results are presented.

  • In this study, we analyzed and experimented about electric continuity for human body safety from green cars. And we compared power systems of HEV and examined about human body effect of current and time. We investigated internal and external standards and regulations for human body safety from high voltage electrical equipments. Indirect contact refers to contact between the human body and exposed conductive parts. According to UNECE R100, ISO 23273-3, ISO 6469-3 and Japanese Regulation Attachment 101, electric continuity between any two exposed conductive parts shall not exceed $0.1{\Omega}$. The value of electric continuity was measured below $0.1{\Omega}$ at the actual condition of green car. We expected that the results of these experiments can utilize to data for electrical safety of green car.

  • Generally, we take a bath to obtain a clean body as well as a good health. Human body generates various physical and emotional changes by stimulations of therapeutic effect of heat and hydraulic pressures. Accordingly, we can obtain not only relaxations but also effects of hydrotherapy. The survey of bathing/showering behaviors and therapeutic effect of heat reactions present elementary data for development of a bathing/showering system. However, there are few existing data for bathing/showering behaviors and effects. Consequently, surveys were performed to know patterns of bathing and showering, and relations between physiological changes and water temperature were examined by partial bathing on human body in this study.

  • The purpose of this study is to analyze how the human body having more muscles than its degree-of-freedom modulates an effective stiffness using redundant actuation, and to apply this concept to the design and control of advanced machines which requires adaptable spring. To investigate the adaptable stiffness phenomenon due to redundant actuation in the human body, this paper derives a general stiffness model of the Human body. In particular, for a planar 1 DOF human arm model, a planar 2 DOF human arm model, a spherical 3 DOF shoulder model, a 4 DOF human arm model, and a 7 DOF human arm model, the required nonlinear geometry ad the number of required actuator for successful modulation of the effective stiffness are analyzed along with a load distribution method for modulation of the required stiffness of such systems. Secondly, the concept of motion frequency modulation is introduced to show the usefulness of adaptive stiffness modulation. The motion frequency modulation represents a control of stiffness and / or inertia properties of systems. To show the effectiveness of the proposed algorithm, simulations are performed for 2 DOF anthropomorphic robot.

  • The objective of this study is to review the expressive effect of fashion illustrations and to enlarge its expressive range by analysing the correlations between fashion illustrations and surrealistic expressive characteristics. The results are as follows. The surrealistic expressive methods of fashion illustration such as depaysement and automatism have been used by many foreign and domestic fashion illustrators. I think that these methods reinforce the subjective aspect of expressive effects and enlarge the transmitting function of fashion message. The elements of expression are divided into color, texture, shape/form and space. Subjective colors rather than natural colors are used for the surrealistic expressive effect of color in fashion illustrations, and illusion of space is expressed by the change of brightness. The surrealistic expressive effect in fashion illustrations distorted the experience of factual texture and disturbed the visual texture. The use of tactile texture presented strange effects perspectively. The objects of shape in fashion illustrations were mainly human body. The form of human body presents reconstituted and reinterpreted figure by transformation or distortion according to the intention of the artist rather than realistic and physical form. In fashion illustration, the transformation of the human body itself whose body parts get separated, superposition of exterior material and human body, and the distortion of human body by the change are done. Space is where background and shapes are inter-penetrated because they are ambiguous and untransparent, and where all are in disorder and unbalance. The method of projection uses distance perspective, multiple perspective and amplified perspective representation, and forms a psychological space feeling. And I think the use of surrealistic expressive methods are very useful for the subjective sensitiveness and the transmission of a fashion message, and presents a possibility to develop a new expressive method.
