  • Research on walking assistance exoskeletons that provide optimized torque to individuals has been conducted steadily, and these studies aim to help users feel stable when walking and get help that suits their intentions. Because exoskeleton auxiliary efficiency evaluation is based on metabolic cost savings, experiments on real people are needed to evaluate continuously evolving control algorithms. However, experiments with real people always require risks and high costs. Therefore, in this study, we intend to actively utilize human musculoskeletal simulation. First, to improve the accuracy of musculoskeletal models, we propose a body segment mass distribution algorithm using body composition analysis data that reflects body characteristics. Secondly, the efficiency of most exoskeleton torque control algorithms is evaluated as the reduction rate of Metabolic Cost. In this study, we assume that the torque minimizing the Metabolic Cost is the optimal torque and propose a method for obtaining the torque.

  • 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.

  • It is really hard for the material factors to basically improve quality of life, since it is the only partial means of the survival and activity of life. Development of Eigen Shin-Tou-Jil(Proper Body·Earth materials), therefore, must be concentrated on providing man with essential meaning of life, not with simply economic advantage. Eigen Shin-Tou-Jil(Proper Body·Earth materials) which is formed through long passage of time in the original environments that include the climate and nature features of a special region, the representative examples are like Korea Bong-sam(a kind of genseng) of Yellow Earth etc. Unfolding the Eigen Shin-Tou-Jil(Proper Body·Earth materials) by the Algorithm of Human-ware means the development for manifesting individual eigen motives and traits as subject of behavior(Gene-ware). It is because all plants, animals, inanimate objects, including Human, have evolved with their own values in the ecosystem. It was reported that a Baeksong(white pine tree), grown well up in TongEeDong, Seoul, Korea had rarely grown up during the period suppressed by Japan. By the developments of Bio-Engineering, we also found that 40% of gene base sequence of C. Elegance(a kind of worm) is identical to that of characteristic Human. In this reason, through considering common characteristics between Human and Nature, the developments of Eigen Shin-Tou-Jil(Proper Body·Earth materials) must begin with epoch for manifesting and understanding individual's Eigen motives and traits as subject of behavior(Gene-ware)

  • The resonance behaviour needs be understood to identify the mechanisms responsible for the dynamic characteristics of human body, to allow for the non-linearity when predicting the influence of seating dynamics, and to predict the adverse effects caused by various magnitudes of vibration. However, there are currently no known studies on the effect of vibration magnitude on the transmissibility to thoracic or lumbar spine of the seated person, despite low back pain(LBP) being the most common ailment associated with whole-body vibration. The objective of this paper is to develop a proper mathematical human model for LBP and musculoskeletal injury of the crew in a maritime vehicle. In this study, 7 degree-of-freedom including 2 non-rigid mass representing wobbling visceral and intestine mass, is proposed. Also, when compared with previously published experimental results, the model response was found to be well-matching. When exposed to various of vertical vibration, the human model shows appreciable non-linearity in its biodynamic responses. The relationships of resonance for LBP and musculoskeletal injury during whole-body vibration are also explained.

  • These days, the fantastic in opposition to classic beauty becomes a genre of creative body expression. The purpose of this study was to analyze the expressive characteristics of body types and meanings in recent fantastic fashion illustration. The method of this study was to analyze recent documentaries, fashion books, internet web site and so forth. The results were as follows: In literatures, pictures and movies, the category of the fantastic body's expressive types were classified as dominant mutant based on SF, multi body or fragment body by disruption, heterogeneous compound based on myth, personified humanoid and non substance in supernatural boundary. The dominant mutant based on SF was expressed image morphing, composition of machine image with body and modern metamorphosis of classic SF body. It means propensity to post-feminism and reservation of meaning analysis based on human unconsciousness. The multi body or fragment body by disruption in fashion illustration was expressed distorted composition of same body pictures, replacement of different bodies, deconstruction and partial omission of body and composition of meaning or non meaning images. It means permanence of self and basic narcissism. The heterogeneous compound based on myth was expressed general composition or optical illusion of various and aggressive animal motive. It means reinterpretation of original myth, metaphor of basic femme fatale, pursuit of permanence and sign of primitive mind in unconsciousness. The personified humanoid was expressed real human body description of mannequin or ball joint doll and anthropomorphism of robot image. It means representative satisfaction and nostalgia of childhood. The non substance in supernatural boundary was expressed grotesque description of ghost, zombie, vampire, angel, fairy, using of symbolic red, black color and non body. It means human's basic desire about immortality and taboo. Through the result of these study, the expression of fantastic body in fashion illustration will expend expressive method and we will understand human and cultural codes of today.

  • 오늘날 워크맨, 모비일폰, 노트북PC, PDA와 같은 제품들은 우리 몸과 함께 이동하고, 인터넷과 같은 가상헤계에서는 아바타(Avatar)라는 우리의 분신이 사이버상에서 우리들 육체를 대신해 행동하고 있다. 이러한 제품들은 우리 인간의 몸과 관련된 것들이며, 이렇게 인간의 몸에 물리적으로 붙으며 아울러 정신적 결합의 의미를 가지는 것을 인간과 제품의 결합이라 할 때에, 이러한 제품들을 현실과 가상을 포괄한 인간과 제품의 결합관계로서 접근하여 알아볼 필요성이 있다. 연구결과로서 고대로부터 지금 현재까지 인간의 몸과 결합한다고 하는 제품들을 꾸준히 발견할 수 있었고, 최근에 와서 그 양상은 긴밀한 관계로서 결합과 이동성향이 강하게 나타남을 알 수 있다. 이러한 배경에는 사회문화적으로 이분법적 사고의 붕괴, 혼성모방, 사이버문화, 테크노문화, 정보유목민개념 등이 나옴에 따라 인간과 기계의 구분이 모호해지는 현상과, 제품이 소형화되고 인간을 흉내 모방하거나 네트워크화되어 인간과의 결합성향이 더욱 가속화되는 변화에 있다. 따라서 상호간 결합성향이 더욱 가속화되는 변화에 있다. 따라서 상호간 결합성향이 짙어감에 따라 인간의 몸과 제품을 하나로 바라보아 신체적, 정신적측면, 제품적 특성을 모두 포용한 가장 적절한 복합체로서 접근하는 상호결합적 관점으로서의 변화가 필요하다. 상호결합제품은 인간의 정신, 육체와 전적, 부분적으로 결합하여 인간의 몸을 중심으로 물리적 안착을 하여 지속적 접촉을 가지는 것이라 정의할 수 있다. 그 결과 이동성을 가지는 고대의 도구들은 단순이 인간의 기능확장에 머무르고 신체와 관련된 결합들이 많았으나, 현재로 올수록 신체와 정신에 동시결합하는 제품들이 많아지고 있다. 이러한 제품들은 인간의 몸과 결합방식별로 여러가지 형태로 결합하고 있으며, 기능이 중층화되고 인간의 몸과 물리적으로 가까와지거나 커뮤니케이션형태가 고도화되고, 기존에 인간의 몸에 잇던 제품들을 통해 재발생되는 형식을 취하고 있다. 또한 제품들간에 적외선, 무선통신 같은 방식을 토해 교신하고 있으며, 외형발산성향이 강하여 장신구나 옷과 같이 변하고, 가상아바타의 경우 인간의 육체를 모방하고 인간의 행동을 대신하는 특징을 가지고 있다.
