  • Subject : The Association between Extraordinary Organs(奇恒之腑) and Eight Extra Meridians(奇經 八脈). Objectives : This study research some special aspects of Extraordinary Organs and Eight Extra Meridians which differentiated from ordinary Organs and Meridians, and the association between Extraordinary Organs and Eight Extra Meridians. Methods : First, researched classification standard and physiological characteristics of Extraordinary Organs through studying various chapters of HuangdiNeijing. Second, researched The Association between Extraordinary Organs and Eight Extra Meridians through studying on the origin of Eight Extra Meridians in HuangdiNeijing. Third, from accompanying researching the subject of Cheon-gye(天癸) and human body shape, draw synthetic hypothesis on the relationship among ordinary Meridians and Organs, muscles and skins of body shape, Extraordinary Organs and Eight Extra Meridians. Results & Conclusions : The following conclusions could be drawn. 1. Extraordinary Organs afford background for shaping human body. This is same as the properties of the earth which afford background for shaping all creations. The physiological characteristics of Extraordinary Organs is intermediation and regulation between Ki(氣) of Five Viscera & six Bowels and shape of muscles & skins in human body. 2. The origin of Eight Extra Meridians could be found in HuangdiNeijing. The collateral Meridians of the Uterus and Epiglottis Meridian are specifically formulated to supplying for the Uterus or Epiglottis. From this we can draw The Association between Extraordinary Organs and Eight Extra Meridians, that is Eight Extra Meridians are specifically formulated to supplying for Extraordinary Organs. 3. The Cheon-gye(天癸) is doing significant function in Eight Extra Meridians supplying for Extraordinary Organs. Cheon-gye concerned to growth, secondary sexual characters, generative function, aging process. Theses are all concerned with the changing of human body shape. Cheon-gye urge to change the body shape with following the human life cycle. 4. Human body has vertical symmetry because preserve its shape from the gravitational force. Eight Extra Meridians place at the middle or flank axis of human body, thus do physiological function that assistant human body have vertical symmetry shape. The purpose of shaping vertical symmetry is securing space what the inner Twelve Regular Meridians and Five Viscera & six Bowels create there own physical changes. On the other hand the inner changes need deviation between left and right because of mobility and circulation of force. But human body change the shape in the process of growth, reproduction, aging. Eight Extra Meridians play role at time of these processing, thus they deeply concerned to human's life cycle and reproduction. 5. Eight Extra Meridians and Extraordinary Organs were named 'Extra' because of some special aspects which differentiated from ordinary Meridians and Organs. All they play role to have vertical symmetry shape of human body and maintain the shape, thus they deeply concerned to the change of human life cycle. These shaping maintaining and the change of human life cycle are very special aspects of human body. So they needed to differently cognize separate to the ordinary changes of Five Viscera & six Bowels and Twelve Meridians at inner space.

  • On the human-rifle system, the human body is affected by the firing impact. The firing impact will reduce the firing accuracy and change the initial shooting posture. Therefore the study of biomechanical characteristics using human-rifle modeling and numerical investigation is needed. The musculoskeletal model is developed by finite element method using beam and spar elements. In this study structural analysis has been performed in order to investigate the human body impact by firing of 5.56mm small caliber machine gun. The firing experiments with the standing shooting postures were performed to verify analytical results. The result if this study shows analytical displacements of the human-rifle system and experimental displacements of the real firing. As the results, the analytical displacement and stress of human body are presented.

  • The purpose of this study is to categorize and analyze the body shape of obese Korean men that are needed for industrial design. Using the anthropometric data that were surveyed through the 5th Size Korea project, this study was conducted in four steps mostly through the multivariate statistical analysis. In the first step, Broca, BMI, WHR indices are used to define obesity and select obese men from Korean adults and teens. After 34 human anthropometric variables are supposed to be related to obesity were extracted through an expect survey. In the second step, a factor analysis was executed for those human anthropometric variables. Through this analysis, we obtained the human body factors that are related to the representation of obesity. Then the third step, we used a cluster analysis from the result of the factor analysis. And ANOVA analysis was also conducted to obtain the critical obese human anthropometric variables. In the final step, we found the characteristics of the body types of obese men according to clusters and ages. The body types of obese men classified in the study are expected to be applied to product design for clothing, furniture, automobile packaging, etc.

  • The purpose of this study is to investigate the characteristics of Grotesque in Contemporary Fashion. The study selected the 1990's or after fashion material by the material of both $pr{\hat{e}}t-{\grave{a}}-porter$ collection and haute couture collection based on Europe. These days, the characteristics of grotesque have been categorized into four groups based on the theory of representative scholars of the Post Modernism era. The results are as follows. ${\cdot}$ The devilism creates shocking and destructive cruelty and fear by using frightening object and mysterious and devilish motif which symbolize the death of fashion ${\cdot}$ Hatred produces physical destroy of human body, anatomical expression inside human body, cruelty by naked sex expression, pains, cruel treatment, disillusion and unpleasantness, which have been caused by the disturbance and ideological confrontation of the society, and is said to be a kind of self-confession against dislike and fear of the disclosure of human existence. ${\cdot}$ Playfulness distorts and exaggerates clothes and human body forms, and produces abnormality and mystery because of vague sex identity. The playfulness of fashion can open fixed and closed world and lead it flexibly. ${\cdot}$ Heterogeneity is divided into both primitiveness and virtuality The primitiveness distorts or transforms human body through the human body decoration of primitive race, and expresses a grotesque form combining human being and other animals. It gives a question to the existence of alienated and suppressed life through the world. in which everything is mixed and not separated. The virtuality introduces not only cyborg form combining human being and machines but also state of the art technology factors, so that it emphasizes non-mechanical and non-human grotesque images.

  • This research focuses its study on the expressions of the visual images of the fashion illustration as a part of visual art and utilizes it to formulate the theoretical basis. Main findings of our research are as follows: The structure of communications in the fashion illustration is based on the four elements. They are the expression of the texture, drawings, composition, and the human body and dress. The characteristics in expression of texture level in fashion illustration can be the expression of creative texture in pattern or crease, and also can be expressed as various collage and photomontage by computer graphics. Secondly, the analysis on the characteristics of the drawings show that the drawing skills are imagination and sequential drawings. Thirdly, the characteristics of composition method are mainly shown as the application of plane composition which was previously used in avant-garde arts. Fourthly, most of the human body in the fashion illustrations are shown as the results of simplification, exaggeration and deformation in human body and also expressed or analyzed by the method of the body modification. Based on the above findings of this research we conclude that the way of expression in the fashion illustration is very similar in its composition as in visual art. However, they also show differences between the two in expression method or the method for the image development in specific expressions.

  • In this paper, dynamic modeling with viscoelastic properties of a human body resting on a seat is presented to quantitatively analyze ride quality of passengers exposed to vertical vibrations. In describing the motions of a seated body, a 5 degree-of-freedom multibody model from the literature is investigated. The viscoelastic characteristics of seats used in railway vehicles are mathematically formulated with nonlinear stiffness characteristics and convolution integrals representing time delay terms. Transfer functions for the floor input are investigated and it is found that these are different in accordance with the input magnitude due to nonlinear characteristics of the seat. Measured floor input at the railway vehicle is used to analyze realistic human vibration characteristics. Frequency weighted RMS acceleration values are calculated and the effects of the seat design parameters on the frequency weighted RMS acceleration values are presented.
