  • This paper presents a methodology for satisfying the thermal comfort of Indoor environment and reducing the summer peak demand power by minimizing the power consumption for an Air-conditioner within a space. KEPCO(Korea Electric Power Corporation) use the fixed duty cycle control method regardless of the indoor thermal environment. This method has disadvantages that energy saying depends on the set-point value of the Air-Conditioner and DLC has no net effects on Air-conditioners if the appliance has a lower operating cycle than the fixed duty cycle. A variable duty cycle estimates the PMV(Predict Mean Vote) at the next step with a predicted temperature and humidity coming from the back propagation neural network model. It is possible to reduce the energy consumption by maintaining the Air-conditioner's OFF state when the PMV lies in the thermal comfort range. The proposed methodology uses the historical real data of Sep. 7th, 2001 from a classroom in seoul to verify the effectiveness of the variable duty cycle method comparing with fixed duty cycle. The result shows that the variable duty cycle reduces the peak demand to 2.6times more than fixed duty cycle and increases the load control ratio by 8% more. Based on the variable duty cycle control algorithm, the effectiveness of DLC is much more improved as compared with the fixed duty cycle.

  • Sediment cores were obtained from Upo and Mokpo in Upo Wetland and core samples were divided by depth into 20 ~ 21 subsamples. The heavy metal concentrations of Fe, Mn, Zn, AS, Cu, Cd, Ni, Pb, and Cr in the sediments of each depth were determined by ICP-MS. The texture of sediemnts from Upo Wetland appeared to be clayey silt with average grain size of $7.52{\sim}11.15{\mu}m$ for physical properties. It was found to have a clear tendency of depth profile with respect to TOC and ignition loss. Organics were stabilized in the range of 0.5 ~ 0.7 % TOC and 8 ~ 9 % ignition loss in 30 years, whereas, the surficial sediments have the highest concentrations of about 3.0 % of TOC and 13 ~ 15 % ignition loss. Those are much higher than the values of the main stream, the Nakdong River, which reflects the deposit of biodegradable organics from plants and other lifes. The vertical distribution of heavy metals in two sediment cores was investigated to elucidate historical trends of heavy metals deposited into Upo wetland. The depth profile concentrations of each heavy metal were compared and discussed with the Concensus-Based Sediment Quality Guidelines for freshwater ecosystems. All the Cd data for the vertical distribution in the sediments were detected above PEC value for Cd, which predict harmful effects on sediment-dwelling organisms expected to occur frequently. The concentrations of Zn, Cu, and Cr in all sediment samples for depth profile were detected below the TEC values, which provided a basis predicting the absence of toxicity by Zn, Cu, and Cr.

  • The purpose of this study was to understand sexuality expressed in fashion in a discursive view and reinterpret sexuality represented in fashion in the 19th century in Foucauldian post-structural perspective. As for methodology, at first the conception of sexuality was examined from structural feminism to post-structural pluralism by a literature review and discussed in relation with the matters of body and fashion on the basis of Foucault's discourse. Then, sexuality represented in the 19C fashion as a case study was re-estimated in terms of power relationship between dominant and oppositional discourses and mainstream fashion and anti-fashion as well. The conception of sexuality in Foucauldian post-structuralism maintains the view of plural sexuality, which floats by discourse and power produced in a specific historical context. In the Foucauldian perspective sexuality expressed in the mainstream fashion and anti-fashion in the nineteenth century shows the following aspects. The mainstream fashion in the middle and latter of the 19C made the clear sexual difference in dress of plain and functional male suit and extravagant and decorative female dress on the center of bourgeois masculinity in the context of modernity and capitalism. Although anti-fashion was also co-existed with the mainstream fashion, it was criticized by the Victorian people. It codifies sexual ideology of the binary opposition of male domination and female subordination. Therefore, the traditional sexual ideology in the 19C is a capitalist value, which gives a priority to bourgeois man's profits, and the Victorian discourses of sexuality constructs the clear sexual difference in dress in the period.

  • The area of domestic urban design and architecture has established its original characteristics as various programs and functions were created in the drastically changing society. Such features have been presented in a certain type of patterns or unique formations, which demand a gradual development of designs in harmony with the functions and roles of the city and thus designers are forced to continue thinking deeply on this matter in their own perspectives. In particular, such demands are outstandingly high in reality in historical cities such as Andong, which this study works on. As the design contest winner is based on the geographical characteristics and locality, Confucianism and seonbi(Korean classical scholar) spirit, which are regarded as a philosophy of value, how the traditional concepts could be reflected in the plan was the focus of the discussion. The conclusions deduced from such a background include the following. First, it is necessary to make an approach on the basis of the concept in traditional architecture at the complex planning level based on the ideology in the implementation plan that requires traditionality for a complex design with contemporary functions. Second, it is important to approach this as an exploration of a solution to globalize Confucian culture in the future based on the cultural characteristics of the region and the environmental characteristics of the surroundings. Third, beginning from a concept that explains the complex to a concept that explains individual buildings, it is necessary to reflect characteristics in which the realization of a traditional space is planned in three dimensions.

  • On the contrary to the general principle of private law, carriers' liability for passengers and cargo owners have been quantatively limited in some cases. The author traces the rule of liability limitation in the law of Korea and United States to verify two hypotheses. The first hypothesis is that the rule of liability limitation has been introduced to motivate investment when new technology with high risk has been adopted in business. The second hypothesis is that the rule of liability limitation can be maintained only when damages have been fully compensated. The former is a necessary condition for liability limation, and the latter sufficient condition. There are strong evidences for the first hypothesis. Navigation or aviation, artificial satellite lauching, urban transportation system are good examples. The second hypothesis is supported by the fact that there have been continuous controversies on the Warsaw System, including the failure of ratification of Montreal Additional Protocols No.3 & 4 by the U.S. Senate and voluntary removal of liability limitation by the Japanese airline companies. Loss of cargo can be compensated fully, but damages from personal injury and death not. The value of human body and life is not easy to be estimated. Passengers, moreover, do not usually buy insurance for accidents in travel. Passengers do not accept insurance premium as the cost of being whole and alive. They do not accept accident rates realistically. They have no bargaining power in dealing with insurers. The rule of liability limitation in personal losses would not be supported in future because damages have not fully compensated.

  • The Gamrotenghwa of the Choson Dynasty is a unique genre of buddhist painting in that the destiny of the dead souls and the guidance to nirvana are expressed in reality. More than 50 of the Gamrotenghwa are known to be present, and the lower part of the paintings includes a wide assortment of folk customary scenes reflecting the social life style of the time when the painting was drawn, such as difficulties in life. public life, punishment and war. Changes in the costume of the people shown on the customary scenes of the Gamrotenghwa according to the time based changes in painting style were investigated in this study. The results are summarized in three points. First, the costumes of bureaucrats showed a tendency of preservation without any major changes in the painting. On the other hand, costumes of public and entertainer in the scenes were very close to those worn by the people at that time. The realistic description of public life in the painting may establish the value of the Gamrotenghwa as the historical documents. Second, the costume of the people in the painting showed a dual structure as the social positions; bureaucrats wore various official hats, large coats and belts to expose their social prestige. while the general public wore simple and convenient clothing which is divided into shirt and pants. The dual structure of the costume in the painting is in well accordance with that of the later period of Choson dynasty, suggesting that the customary scenes in the painting represent the social life style of the period. Finally, the customary scenes in the Gamrotenghwa are very variegated. which shows a variety of beauty of wearing even though they look coarse in a sense. The diversity of wearing beauty in the picture may contribute to the recreation of the beauty of shape in the new design of Hanbok.

  • Yoon Gil-Young(1911-1987) was a frontier of the field of Traditional Korean Medical Physiology(TKMP) who was academically active since mid 1950s until early 1970s. He wrote several important papers and books. Among his writings, "A Study on the Methodology of Traditional Korean Medical Physiology", which was published serially in the "Korean Oriental Medical Journal" from June 1966 until March 1967, played an important role in establishing the contemporary TKMP and showed his academic stance on Traditional Korean Medicine(TKM). This review will evaluate this paper's contribution to the establishment of TKMP in historical context, summarize the unique characteristics of his understanding of TKMP by analyzing the text, and then based on those information, examine his view on TKMP and TKM. Historically, this paper was written in transition period from the traditional TKM knowledge system to the modernized one. Aim of this paper was to provide a methodology for establishing TKMP as a scientific knowledge system like that of the western medicine. Based on his study of Yin-Yang theory and theory of five circuits and six qi in Huangdi's Internal Classics, he suggested those theories as methods to observing life phenomena and systematizing the observations. And he regarded these methods as of great value in determining the unique characteristics of TKM compared to those of western medicine. Through re-reading this paper, it was found that he had pride and confidence in the methodology of TKM, and also that he thought in scientizing and modernizing TKM it was very important to understand and efficiently put in use the methodology of TKM. It was also found that his view on TKMP and TKM was pro modernization.

  • vcrtical filing 개념이 일본에 도입된 것은 20세기 초였다. 이것이 사무관리의 기원으로 간주되고 있다. 이차대전 후 점령군이 미국식의 문서관리법을 소개했고 filing system이 일반화되었다. 그러나 filing 방법은 사무직원에게 필요한 기술로 인식되었다. 사무문서는 양적으로 증가하고 사무관리에 있어 정보자원으로서의 가치를 인정받게 되었다. 이러한 움직임이 기록관리학의 도입과 발전에 기초가 되었다. 사무실에서의 기록관리 개념과 방법을 전파하기 위해 학술연구와 교육체제를 확립할 필요성이 생겼다. 그런 상황 속에서 1989년도에 일본기록관리학회가 설립되었고 1999년도에는 스루가다이대학교에 기록관리학 대학원 과정이 개설되었다. 이들은 일본에 있어 기록관리 연구와 학술활동의 중심이 되고 있다.
