  • The fashion of late Yi dynasty had explored a possibility of new fashional beauty from its own experiences throughout the history of Korean fashion excluding any interference of foreign fashions, and brought out some characteristics ; first, the aesthetical value focused on the more human fashion resulted in the exposure of waist. This aesthetical change in the fashion of late Yi dynasty produced out results as follows ; the length and width of jacket became short and narrow maintaining the basic form, while the width of skirt became increased to be contrasted exceptionally with the upper coat. This mode of fashion reveals the transitional movement from the emphasis on balance to that on unbalance in the late period of Yi dynasty. But regarding the fact that the proportional change by the ways of putting on skirt became to be similar to the golden ratio, we can see many examples throughout the folk paintings by Shin Yun bok, we find that the fashional beauty of that age pursued ideal harmony and unity all the time being in spite of its tendency toward non-refinement. Second, we see another peculiarity in the mode of woman's fashion from the paintings by Shin Yun-bok who always depicted the hu-man nature frankly. For example, the jacket became shorter to emphasize lady's slim waist, and underwears began to be exposed after the upper part of skirt had been to expose lady's waist while the bottom line pulled up highter than before. Thus, as the function of robe had changed from a mere means of covering into an expression of beauty, the fashion of late Yi dynasty began to express a perfectly new beauty possessing an erotic mood and sensu-ality of a woman, which was its inner aesthetic need. Third, this emergence of new fashional beauty made the mental value of man and the aesthetic views of that time quite different from the previous ones, and finally there came various expressions of a new beauty. There-fore, the woman's fashion of late Yi dynasty is noted for the exposure and emphasis on the body line of a woman after the aesthetic view-point had changed of time toward pragmatism and humanism, while upholding the traditions of Korean clothes and pride for the nation. And our ancestors realized very Korean fashional beauty by pursuing the expressional ways of gentle, indirect emphasis upon the feminine and natural beauty to exclude and ar-tificial, direct and straightforward exposures and images.

  • The purpose of this study is to develop the algorithm which can control muscle power assist robot especially for elderly. Recently, wearable robots for power assistance are developed by many researchers, and its application fields are also variable such as for medical or military equipment. However, there are many technical barriers to develop the wearable robot. This study suggest a control method improving performance of a wearable robot system by using a EMG signal of major muscles and a force sensor signal as command signal of system. The result of the robot Prototype efficiency experiment, the case of Maximum Isometric motion it suggest 100% power of muscle, the man need only 66% of MVIC(Maximum Voluntary Isometric Contraction) to lift 5kg dumbbell without robot assist. However the man needs only 52% of MVIC to lift 5kg dumbbell with robot assist. Therefore 20% muscle power increased with robot assist. Also, we designed light weight robot mechanism that extract the command signal verified and drive the wanted motions.

  • Myoepithelioma was recognized as a histological distinct entity by the World Health Organization (WHO) in 1991. Myoepithelial cells are believed to be of ectodermal origin. In salivary glands, the myoepithelial cells that surround the intercalated ducts are spindled, which is in contrast to the large stellate ones that envelop the acini. Myoepithelioma is a benign salivary gland tumor that consists entirely of myoepithelial cells. A 53-year-old man presented with a 1-year history of a painless mass originating from the right parotid gland. The mass grew rapidly reaching a size of approximately 6 cm. The patient had no facial paralysis. The authors performed right parotidectomy. Immunohistochemistry study of this tumor showed that it was positive for vimentin, positive for S-100, focally positive for pancytokeratin, and focally positive for p63 and that it had a Ki-67 labeling index (below 10%). Additionally, the tumor was negative for epithelial membrane antigen, negative for actin, negative for desmin, negative for CD34 and negative for anaplastic lymphoma kinase. The authors present a case of benign spindle cell myoepithelioma of the parotid gland in a 53-year-old man diagnosed after immunohistochemistry study, describing its importance, along with a brief review of the literature.

  • This paper is designed to show the relationship between the Daesoon Principle and the recent theories like transpersonal psychology(TP) and predicate logic. According to TP there are 3 categories and 8 elements inside of not only human consciousness but civilization; three are pre-ego, ego, trans-ego, and eight are Uroboros, Typhon, Greater Mother, solarization, and repetition of the previous fours. The former is called, for Ken Wilber, the Average mode and the latter, the Advanced mode. I think that Daesoon thought including general Korean National religions belongs to the Advanced mode. I applied the predicate logic or paradoxical logic to understand of the Harmony of God and Man as well as Correspondence of Yin with Yang. The paradoxical logic has been not acceptable through two thousands years in the western tradition. I call the paradoxical logic the E type logic in this paper. The E type logic is most suitable logic for apprehending the Daesoon philosophy to a large extent. Finally my paper may contribute to the globalization of Daesoon mind system.

  • This study was accomplished to investigate the recognition and the using practices about food-nutrition labeling system of 20's consumers. Two hundred and fifty-four man and women were examined using the questionnaire. The results were as follows. 1. The degree of recognition of subjects about food-nutrition labeling system was low (43.3%) and the using practices were even lower (18.1%). 2. The items considered as important were in the order of shelf life, manufactured date and cost. 3. The confidence score to the food-nutrition labeling system of consumers was 3.2 and was higher in the females compared to males. 4. The preferred method of food-nutrition labeling was in the order of picture and graphic type method, table type method and descriptive type method. 5. The expected effects of the current food-nutrition labeling system were easy to select foods for the prevention of the adult diseases and diet therapy. From these results, we might propose the conclusion as follows: Food-nutrition labeling system might be a good source of nutrition information and the consumers'demand for disease-prevention and dietary purpose. Therefore, the agencies concerned should make an every effort for the successful implementation of food-nutrition labeling system.

  • Hemodialysis is a way of treatment for the patients with acute and chronic renal failure. "Marginal man" depicts the enormous amount of stress that hemodialytic patients suffer. It is known that family with chronic illness get stressed along with the patients and they need nursing care also. This qualitative study was conducted in order to identify the family adaptation process in patients with hemodialysis. 6 dyads of hemodialytic patients and caregivers were interviewed for this research. By way of grounded theoretical strategy the data was collected from October 20, 1999 to November 20, 1999. at a hemodialytic unit that was located in Iksan, Chonbuk by the researcher. The main research questions were "What's the adaptation experience of a patient since after being received with hemodialysis?" to the patients, and "What's the family adaptation experience of hemodialysis?" to the caregivers. The collected data was analyzed by grounded theoretical strategy built by Glaser & Strauss in 1967. Results were as follows; 7 grounded concepts were observed from the patients with hemodialysis and 4 grounded concepts were found from the caregivers. Two categories were derived ; 1) Holding hope that is related with treatment 2) Changing a value system.
