Water reuse of effluent is limited, due to bacteria and chromaticity or turbidity which may result in low perception of water quality. Consequently, this study showed a method in the reuse of treated wastewater by a diversified treatment method, with separation of centralized reformation of aeration tank into pre-treatment with minimum installation of facilities, and post-treatment, applying advanced oxidation treatment. A pilot plant experiment was performed using Sym-Bio process adopting an NADH Sensor without modification of the exiting aeration tank. The Dissolved Ozone Flotation process, which is an advanced oxidation process, to treat the remaining organics, nutrients, chromaticity, turbidity and bacteria. As a result in the Sym-Bio process, the biological treatment, even on the condition of single stage reaction tank, the treatment efficiencies of BOD, $COD_{Mn}$, $COD_{Cr}$, SS and T-N were 96.6%, 84.6%, 88.25%, 95.1% and 71.0%, respectively, while that for T-P was 25.0%, which required further treatment. In the Dissolved Ozone Flotation process, the advanced oxidation treatment, the treatment efficiencies of BOD, $COD_{Mn}$, $COD_{Cr}$, SS, T-N, T-P, chromaticity, turbidity, bacteria, coliforms were 78.9%, 34.6%, 28.7%, 48.0%, 70.4%, 82.4%, 84.0%, 74.5%, 99.8% and 99.4%, respectively.

Nucleic acid and protein biosynthese of the glucose-bleached Chlorella cells in relation to the process of the chloroplast reformation were traced, by measuring the changes in the amounts of cell constituents and nuclease activities of the cells during the greening process. The contents of RNA and protein of the glucose-bleached cells decreased significantly, shile the contents of nucleotides and amino acids of the cells increased to compared with those of the control, showing that the biosynthetic activities of RNA and protein of the cells were inhibited severely in the glucose-bleaching process. In the early greening process of the glucose-bleached Chlorella cells the contents of RNA and protein of the cells increased significantly, while the contents of nucleotides nad amino acids of the cells increased to compared with those of the control, showing that the biosynthetic activities of RNA and protein of the cells were inhibited severely in the glucose-bleaching process. In the early greening process of the glucose-bleached Chlorella cells the contents of RNA and protein of the cells increased significantly wihout any increase in the chlorophyll contents showing that the massive biosynthese of RNA and protein proceed prior to the chlorophyll bioynthesis in the cells. The phosphate contents in the DNA fraction of the glucose-bleached cells decreased, but the contents of acid-insoluble polyphosphate increased to compared with those of the control in the early greening porcess, exhibiting that the incorporation of the phosphorus from acid-insoluble polyphosphate into DNA was retarded. In the greening process of the glucose-bleached cells the ribonuclease nad deoxyribonuclease activities of the cells decreased to compared with those of the control, although the initial activities of the both enzymes in the cell were far great compared with the control. Although the initial phosphate contents in the lipid fraction of the glucose-bleached Chlorella cells were more great than the control, the phosphate contents in the lipid fraction of the cells decreased in the early greening process to compared with control, and then increased in the late developmental stages in which massive chlorophyll biosynthesis occured.

Purpose: This study was done to describe the return to work experience of military officers with cancer. Methods: Individual in-depth interviews with 15 participants were conducted between September 2013 and April 2014. Participants were interviewed 1~4 times; interviews continued until the data became saturated. Data were analyzed using Strauss and Corbin's grounded theory. Results: The core category emerged as "living a new life after enduring difficulties". The return to work process consisted of four sequential phases: chaos, positive thought formation, behavior practices, and reformation. Action/interaction strategies used by military officers with cancer to resolve enduring difficulties were controlling emotions, accepting reality, prioritizing health, making efforts to improve relationships, and looking for future jobs. Conclusion: These results will promote understanding of military officers' return to work experience following cancer survival, and will be helpful in developing more effective nursing interventions through enhanced perspectives and insights of practitioners.

During the last half a century the Korean rural society have experienced drastic changes : the retreat of Japan from the colonial interference and suppression in 1945, the Korean war and disorder in the 1950s, the implementation of the first and second five-year economic development plans in the 1960s, the ambitious implementation of the new village movement called Saemaul Undong to modernize the traditionally stagnant rural village in the 1970s, and socioeconomic and political turmoil in the 1980s. In this complex process of change the rural health care system in Korea was grdually reformed. This paper reviews the socioeconomic change and the basis of the changing structure of the health care system in rural Korea, on the basis of the existing literature and secondary data. Thus this is not a research paper but a review article in its nature. After reviewing the past and present situation, the directions and strategies for the reformation of the rural health care system are suggested.

Thesedays, Home Economic in Korea is faced with the danger of a discord caused by the outer pressure of reorganization in the process educational reformation. The first purpose of this study was to examine the characteristics of the informatized society and the changes of families lived in the informatized society. The second was to assert to strengthen Home Economics in the informatized society. Ultimately we suggested an integrative and interdisciplinary model about Home Economics from the ecological and informative perspective. This model consist with three parts: Human development(Child studies, Gerontology, & Adolescent studies) and family studies division(Family relation studies, family resource management studies, & Consumer studies) Environmental division(Clothing and Textiles, Food and Nutrition, & Housing) and HEIS(Home Economics Information System). This classification is correspond with the one Human-Behavioral Environment and Human-Constructed Environment of Ecological theory.

This research surveys the forming process of Practical Korean Costume and its social factors and examines Hanbok reformation. The international mode of '86 Seoul Asian Games and '88 Seoul Olympic Games in the 1980's called for the modernization of Hanbok. It is necessary for us to inherit modernized Hanbok which is endowed with the traditional beauty. The purpose of this research is to develop Practical Korean Costume design for focused on functionality as well as on keeping the traditional beauty This study consist of theoretical study and positive study. Theoretical study has the esthetic characteristics(structure characteristic, formative characteristic and the characteristic of color). Grounded upon survey on brands, I have suggested designs that maintain Hanbok's superiority and functionality to fit modern life. Most of Practical Korean Costume shops could not fractionalize customer. So it need to subdivide and specialize customer and investment to improvement of design. Practical Korean Costume will have to be made to maintain dignity by using high quality materials and a coordinate goods will have to be developed.

During the seventeenth century, Amsterdam experienced unprecedented growth and affluence, and the city developed into the world's staple market playing an indispensable role in Silk Road trade. This era, which coincides with post-reformation Dutch society, also allowed artists to produce art works depicting objects from everyday life, moving away from the earlier religious subject matter. This paper intends to look into seventeenth century Dutch paintings from their social setting, especially focusing on the influence of the Silk Road in the art making process. The paper also looks into the Chinese side of Silk Road interaction and discusses how Chinese porcelain reflects cultural influence from the Dutch. The paper incorporates Silk Road as a methodology to discuss art works departing from earlier practices in art history. This approach allows us to understand art as a product of multi-disciplinary, multi-cultural experience. The methodology invites more discussion on numerous art forms which emerged along the Silk Road trading route to expand and explore the history of East-West cultural exchange.

Insulators for high-voltage and large-power should be endured mechanically the weight of mold bushing itself and the force of pushed from contact with circuit breaker and conductor. But dielectric breakdown could be occurred result from the external circumstances and internal factors such as chemical reaction, partial discharge, change of temperature and the relation of temperature-time in process of casting. Therefore, to get rid of external and internal factors of dielectric breakdown. Furthermore, to prevent the internal cracks, void, cavity which resulted from the contraction originated on the interface between copper and epoxy resin, formed semi-conductive layer with partially carbon painted on copper bar. The PD properties and the insulation qualities of epoxy molded insulators were improved by roles of cushions for the direction of diameter and natural sliding effects as like separated from conductor for the direction of length.
