  • This paper analysed the induced current density characteristics inside human body by extremely low frequency magnetic fields according to varying conductivities of human model. Human model was composed of several organs and other parts of 곳 human body, whose shapes were spheroids or cylinders. Organs taken into account were the brain, heart, lungs, liver and intestines. Applying the boundary element method to the human model, effects of the organ conductivity difference to the induced current distribution were estimated.

  • In this paper, we studied on the potential characteristics of human-body contacted the charging part. A charging part of electrical facilities and the earth are simulated by the e1ectrode pole and conductive rubber plates respectively. As the results of these follows, when the potential distribution of the human-body contacted the charging part is far from the electrode pole, a lot of currents flow through the human-body. Besides human-body non-contacted the charging part is affected by step voltage. Therefore, we could find out the causes of the electric shock accidents and be expected to the data for minimization of human error occurred the workspace.

  • This paper deals with modeling and analysis fer the landing motion of a human-body model. First, the dynamic model of a floating human body is derived. The external impulse exerted on the ground as well as the internal impulse experienced at the joints of the human body model is analyzed. Second, a motion planning algorithm exploiting the kinematic redundancy is suggested to ensure stability in terms of ZMP stability condition during a series of landing phases. Four phases of landing motion are investigated. In simulation, the external and internal impulses experienced at the human joints and the ZMP history resulting from the motion planning are analyzed for two different configurations. h desired landing posture is suggested by comparison of the simulation results.

  • This paper analysed the induced current density by electric field of human body under the 765 kV transmission line considering permittivity and conductivity. As permittivity of human body is very high as $10^6$ at 60 Hz, special numerical computation technique in Surface Charge Method(SCM) for composite media with extremely different properties is applied to reduce calculation error of induced current density and electric field inside the human body. Calculation results show that the average of the induced current density inside human body is about 3mA/$m^2$, which is less than ICNIRP criterion (10mA/$m^2$).

  • Space exploration is one of the dreams of humankind. However, the intriguing environment was a challenge for the human body, where we must counter with many extreme conditions such as thermal support, radiation, microgravity. Life, as well as the human body, developed and evolved in the continuous presence of gravity, especially when living creatures transfer from the ocean to the land. Once this gravitational force doesn't impact on the body, the drastic changes occur. Some of these changes were observed immediately, while others progress only slowly. Since the first orbital flight was performed, several hazards for the organs of the human body were identified [1]. These changes in human physiology can reverse when astronauts return to Earth. This article will review the published findings of the effects of microgravity exposure on the human body.

  • The purpose of this study was to identify the producing process for Korean nursing knowledge as applied by Foucault's discourse analytic method. By Foucault's discourse analytic method, the problem is not what is knowledge but what sort of knowledge is made up through specific level of practice. A Korean body of nursing knowledge has been discussed since 1980. At the end of 19th century, missionaries transplanted western nursing knowledge and method to Korea. Western nursing knowledge and methods have been developed continuously with both merits and demerits to Korean society. Recently our world has be come a global community via advances in transportation and correspondence. Although each person is different in skin color and shape. there is a clear line between Oriental people and Western people. Nursing science is only one in our world. but western humanistic nursing practice based on western worldview and human life has limits. It is natural that the Koreans as Oriental people have a systemic nursing science to reveal the specific experiential and concrete body of nursing knowledge rooted in the Korean worldview and human life. Nursing science is to understand human beings, to promote health. to prevent illness. to restore health. to alleviate suffering and to search for principles needed throughout all of human life. In Korea, now is the quickening period to shape a Korean body of nursing knowledge because of a shortage of nursing language in matters of intellectual recognition, and unfamiliar practical nursing field where there is no familiarity in the system of nursing research methodology. In reviewing articles from the Journal of the Nurses' Academic Society on Korean body of nursing knowledge, it was found that there are two common features. The first, human body and mind are inseperable that is one unit in this world and health is keeping a harmonious relationship between human body and mind. The second, Korean nursing practice is based on human nature and family ties. Accordingly discourse analysis has a good future prospect to produce a Korean body of nursing knowledge for analytic research on body and mind monism and family centered care based on human nature and family ties.

  • A prototype of 3D clothing design system with a direct pattern development function was suggested, reflecting intuitive design functions and design modifications while considering the fit of clothing patterns with the 3D human body in the virtual 3D space. The research method was as follows. Clothing models were created using a 3D design tool, 3ds max on the surface of 3D human body model made by scanning an actual human body. 3D illustrations were completed by revising the fit and sizing of the human body and clothing models. 2D T-shirt pattern was produced 3D illustrations using from a 3D scanning data modeling solution RapidForm 2004, a 2D conversion program for 3D data called 2C-AN, and Yuka CAD. As a result, the following conclusions were made. The fit of the clothing and human body can be adjusted by reflecting individual body figure characteristics and 3D illustrations over the actual 3D body model. Furthermore, intuitive design support functions were intensified overcoming the weak point of existing 3D clothing design system by developing the direct clothing design in the virtual 3D space. 3D illustration design modifications can be directly reflected on clothing patterns from 3D illustrations by 3D clothing design system developed in this study.

  • In this study, we tried to reveal the state of stillness of Cho Ji-Hoon's poem "Silent Night 1" as a healing modifier. The language of poem is synaptically linked to the calmness emotion of the human body, seeking a principle that leads to a state of healing. Therefore, this study was carried out for the purpose of applying the principle to literary therapy program. The silent signal embedded in the poem is encoded into the signals of the sound as it is synapsed to the human body. Encoding of auditory nerves by poem lines is like a Morse code that word and word leave in the human body. The action potential of the auditory nerve is further activated by the potential difference between the word and the word represented by the neural network, such as a Morse code, which is accessed to the human body by such a path. There is worked as amplified potential difference between the words perceived by a sound which is synapsed to the human body and by a silence which is synapsed to the human body. The phenomenon of the words approaching the human body and setting the absence of sound and amplifying the sound is because the words amplifies the Morse codes in the human neural network. At this time, the signals overlap each other. Thereby this poem is increasing the amplitude of the sound. This overlapping of auditory signals appears and amplifies the catharsis. If this Cho Ji-Hoon Poem's principle is applied to literary therapy program in the future, more effective treatment will be done.

민국시기 중국 여성들의 인체미 의식에 대한 연구 -푸뉘자즈(부녀잡지(婦女雜誌))와 링롱(영롱(玲瓏))을 중심으로- (A Study on the Aesthetics of Women's Body in the Chinese Republican Period -Focused on Women's Magazines, Funüzazhi & Linglong-)

  • The Republican Period of China (1912 to 1949) was when the archetypes of thought (constituting contemporary China) engaged in heated rivalry and were directly influenced by Korea through frequent exchanges. This study analyzes the characteristic of Chinese women's aesthetics towards the human body with a focus on visual materials (such as articles and illustrations concerning hairstyle, makeup, skincare, fashion, and gymnastics) featured in the Chinese women magazines of Fun$\ddot{u}$zazhi (婦女雜誌) and Linglong (玲瓏). This study analyzes these magazines and compares them with Korean counterparts. The movement of the developed and controlled human body was a common characteristic of this period; however, compared to the Chinese, the Japanese colonial period of Korea resulted in an introspective self-examination through excessively objectified eyes. Dress and adornment as the symbol of a new civilization acted as the most remarkable signifier. The overlapping of a western image with a Japanese image led to more resistance in Korea. The criterion for the value of a women's external appearance (that traditionally dualized womanly virtues) collapsed and dress was accepted as an expression of individuality instead of as a social class. The human body was traditionally recognized as a microcosm of the universe that dominated the natural principle of Yin-Yang and the Five Elements. However, the ideal human body was postulated and the aesthetic consciousness of the body changed into an imaginary view of the human body that proceeded to keep the body fit for and gave birth to the concept of supplementing the deficiency of the beauty of the human body with dress and makeup.
