To design a beautiful hood fitting an unspecific individual, focusing on body parts such as the head, neck and shoulder requires body size and type information, which applied by physical factors like size, types, and movements, etc. These parts consist of complicated types and structures. Accurate information should be a priority due to great individual differences and low correlation with other body parts. However, there is not a lot of detailed physical information nor design methods for hood design. Therefore, the purpose of this study is to select a study sample "hood" which is a recently emerging fashion item and to expand the necessary physical information for pattern design and draw body size of wearing part on Hood like head, cerbical portion and shoulder. Extract factors to consist on types and after divided into several types, a study comparing each type's physical characteristics was conducted. In order to do that, body measurement data have been collected by statistical treatment and analyzed reference with statistical treatment. The results of the study are predicted to be important data to develop various hood designs for the recent fashion trend. Factor analysis was conducted through main composition analysis about direct measured item on human body and index items. The results of factor analysis, composed factors of body type in this research object were extracted in total of 3 factors. To categorize the head, neck and shoulders of women in their early 20s women and determine their characteristics, variances with factor analysis became operative for Cluster analysis. With these clusters, women in their early 20s were categorized into three types. The results of this study are considered to affect largely for higher physical suitability on unspecified individuals when allowed absence of reference and the fact that body size only limited to item 'head circumstance' in terms of making hat and hood in the case of recent Korea. For the future, an experimental study of hood production should be conducted by using basic data from this study.

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.

The purpose of this study was to set up an effective marketing strategy targeting college women by researching the relationship between weight control behavior and satisfaction with fit of apparel. The results showed that 1) 85.5% of the college women participated in weight control behavior, and 53.5% of them wanted to lose more than 3kg of their weight, 2) both body cathexis and fit satisfaction of college women were generally low. College women were less satisfied with their body and fit of apparel according to the increase of weight control degree. The weight control parts and unsatisfied body parts were almost matched : thigh, abdomen, hip, calf, and weight. The unsatisfied fit of apparel parts were also found to be thigh, hip, abdomen, crotch, pant length that matched each parts, 3) fit satisfaction of neckline, shoulder, midriff, hip, crotch, thigh, calf, and skirt length decreased according to the increase of weight control degree, and 4) weight control group which wanted to lose weight at neck, shoulder, arm, breast, waist, abdomen, hip, thigh, and calf also had low fit satisfaction of neckline, shoulder, armhole, sleeve, breast, waist, abdomen, midriff, hip, thigh, crotch, calf, and skirt length in clothing.

A humanoid is a robot with its overall appearance based on that of the human body. When the humanoid moves or walks, dynamic forces act on the body structure. Although the humanoid keeps the balance by using a precise control, the dynamic forces generate unexpected deformation or vibration and cause difficulties on the control. Generally, the structure of the humanoid is designed by the designer's experience and intuition. Then the structure can be excessively heavy or fragile. A humanoid design scenario for a systematic design is proposed to reduce the weight of the structure while sufficient strength is kept. Lower parts of the humanoid are selected to apply the proposed design scenario. Multi-body dynamics is employed to calculate the external dynamic forces on the parts and structural optimization is carried out to design the lower parts. Because structural optimization using dynamic forces directly is fairly difficult, linear dynamic response structural optimization using equivalent static loads is utilized. Topology and shape optimizations are adopted for two steps of initial and detailed designs, respectively. Various commercial software systems are used for analysis and optimization. Improved designs are obtained and the design results are discussed.

This study investigates the concept of the body in Korean traditional costume by comparing the traditional costumes of the west and those of Korea while focusing on the relationship between the body and dress. In order to make a comparison of the traditional perspectives on the body in western and Korean costumes, this study examines the literature of history, art, medicine, philosophy as well as dress from the mid-fourteenth century to the nineteenth century pertaining to the west and those of the Joseon Dynasty Korea. Western dress assumes apparent formal structures and pursues overall harmony via the completeness of its entities, while traditional Korean dress subordinates the parts to the whole, emphasizing the organic total. Whereas the proportion of bodily structure is stressed in western traditional costume, in Korean costume the body is perceived as a whole. By revealing the body through the three dimensionalities of dress, the focus on the erogenous body parts is shifting in conventional western dress according to changes in aesthetic consciousness, which reflects the western ideas of objectiveness and self-centeredness. In traditional Korean dress, in the space between the body and dress, the emphasis is on planarization of the dress, which assumes the oriental relationship-centeredness concept.

In this study, the effects of oxide layer formed on the contact parts of TiN coated ball and steel disk on friction characteristics in various sliding conditions were investigated. AISI52100 steel ball was used for the substrate of coated ball specimens, which were prepared by depositing TiN coating with 1(m in coating thickness. AISI1045 steel was used for the disk type counter-body. To investigate the effect of oxide layer on the contact parts of two materials, the tests were performed both in air for forming oxide layer on the contact parts and in nitrogen environment to avoid oxidation. From the test results, the frictional characteristic between the two materials was predominated by iron oxide layer that formed on wear tract of counter-body and this layer caused friction transition and high friction. And the adhesive wear occurred from steel disk to TiN coated ball caused the formation of oxide layer on counter parts between the two materials.

The purpose of this study is to provide fundamental information for standardization of 3D body measurement. This research analyzes errors occurring in the process of extracting body size from 3D body scan data. First, as a result of analyzing basic state of the 3D body scanner's calibration, the point number of each section was almost the same, while the right and left as well as the front and back coordinates of the center of gravity are not, showing unstable data. Nevertheless, the latter does not influence on the size of cylinder such as width and circumference. Next, we analyzed point coordinates variations of scan data on a mannequin nude by life casting. The result was great deflection in case of complicated or horizontal sections including the reference point beyond proper distance from centers of four cameras. In case of the mannequin's size, accuracy proves comparatively high in that measurement errors in height, width, depth, and length dimension occurred all within allowable errors, only except chest depth, while there were a lot of measurement errors in a circumference dimension. Secondly, analysis of accuracy of automatic extraction identification program algorithm presented that a semi-automatic measurement program is better than an automatic measurement program. While both of them ate very acute in parts related to crotch, they are not in armpit related parts. Therefore, in extracting of human body size from 3D scan data, what really matters seems to parts related to armpits.
