The average BOD concentration was found to be about 269mg/L before a process innovation, but after the innovation, it became 30mg/L, which satisfied the effluent standard of 120mg/L. The removal effluent standard of 120mg/L. The removal efficiency was about 60～80%, and the concentration of the treated water was found th be low. after the process innovation, the average COD concentration was 29mg/L, and the CODmn removal efficiency became low to the level of about 65～76%, which was found lower than the effluent standard of 130mg/L. After the process innovation the SS average concentration of the treated water was 13mg/L, which was lower than that before the innovation (32mg/L). By the activated sludge process innovation, the SS removal efficiency was improved to be 30～70%. The average concentration of total coliform before the process innovation was 6100 count/mL because an Activated sludge process only occasionally pass over the allowed standard(The average number of the total coliform of Activated sludge process treated water was about 8100 count/mL), UV disinfection process was introduced. after the introduction, the average number of the total coliform was 1800 count/mL, which satisfied the allowed effluent standard of 3000 count/mL.

In spite of the increasing significance on a scale of building measurement unit and its system having been used in many areas of architecture, only a few researchers carried out the studies on a specific period. It is even harder to find a research results dealt in view of architecture. This research gives a focus on different types of scales employed in the ancient buildings and their sites, based on the research results of unit scale or scales found in recent excavations. After the review of literature on the scales widely used in the ancient times and of the various types of scales excavated archeologically, a kind of scale unit system that had been widely and extensively employed throughout the period of 'Three Kingdoms' could be revealed. The scale system is possibly able to be applied to estimate the exact scale of buildings and their sites as well in that era. The research results show that the scale and its system employed in the East and West buildings and their sites of 'Kum-dang' in 'Mi-ruk Sa' temple are different from 'Kokuryo' scale that was believed in to be used in the temple. Contrary to the suggestion by excavation report on the type of scale employed in the buildings their sites, a scale of 29 centimeters, similar to that of Tang, was employed. It was also found that one module consists of three 'Chuk's of 88.8 centimeters. Based on this scale system, we could conclude that three modules of the buildings on the front and two and half modules of them on the sides were explained by this scale and its system.

어육장과 시중 판매되는 소스의 휘발성 향기 성분들을 GC-SAW 전자코를 이용하여 분석하였다. 어육장은 담그고 1년 동안 발효·숙성 하면서 2개월 간격으로 액체부분만 취해서 분석하였고 숙성 1년이 지난 후에는 가열을 하였다. 소스는 주 원료가 다른 6종을 구입하여 시료로 이용하였다. 발효·숙성이 진행됨에 따라 어육장의 휘발성 향기 성분은 감소하였으며 숙성 후 가열 처리 한 결과 초기 머무름 시간에서 새로운 peak가 여러 개 생성 또는 증가함을 보였다. 쇠고기 추출물, 가쓰오부시, 멸치액젓이 주원료인 소스는 전자코 분석 결과 주 원료에 따라 peak의 분포와 면적의 크기가 서로 다른 패턴을 보였으며, 이는 어육장의 최종 시료와도 달랐다. 어육장과 소스의 향기 성분을 머무름 시간에 따라 주성분 분석을 하여 원료에 따른 향기 패턴에 차이가 있음을 나타내었으며 어육장은 제조 시 사용된 재료로 인하여 쇠고기와 멸치액젓이 주 원료인 소스 사이에 제 1주성분값이 나타났다. 이는 식품의 복잡하고 미묘한 향만을 객관적으로 관찰 한 것으로 향후 맛의 차이에 대한 연구도 병행되어야 할 듯 하다.

This survey was accomplished to compare the characteristics of water quality and algae at the Daechung Dam with those at its regulating reservoir from the year 2003 to 2005. In the case of Daechung Dam, three sites, such as the area near dam body, the Mooneui intake station, and Chudong intake station, were selected averaged data were used for the comparison. The water quality of the Daechung Dam are an follows; temperature is from 4 to 25℃(average 15), pH is from 7.3 to 8.6(average 7.9), DO is from 5.7 to 13.0mg/L(average 9.9), BOD is from 0.7 to 1.7mg/L(average 1.1), COD is from 2.5 to 4.4mg/L (average 3.1), SS is from 1.1 to 9.8mg/L(average 3.2), total coliform is from 0 to 37MPN/100mL(average 11), total phosphorus is from 0.008 to 0.074mg/L(average 0.022) and total nitrogen is from 1.087 to 2.175mg/L(average 1.492). The water quality of regulating reservoir are an follows; temperature is from 1.0 to 24.0℃(average 13), pH is from 6.7 to 8.2(average 7.6), DO is from 5.9 to 13.2mg/L(average 9.2), BOD is from 0.3 to 1.8mg/L(average 0.8), COD is from 2.4 to 5.3mg/L(average 3.8), SS is from 1.2 to 50mg/L(average 9.0), total coliform is from 0 to 260MPN/100mL(average 56), total phosphorus is from 0.005 to 0.224mg/L(average 0.04) and total nitrogen is from 1.123 to 5.227mg/L (average 2.3). The water quality of regulating reservoir had been the Class Ⅱ raw water criteria ein years ago, but it has been improved to Class I recently. Whereas the water quality of the Daechung Dam has been maintained as Ⅱ except COD.

This study was to investigate the effect of Jubak(Sulchigegie) on the physicochemical properties of pork. A pork was cooked in a pot opening the lid with the Jubak for 20 min and then covering the lid without Jubak for 20 min at 100℃. Effect of the added amounts of Jubak on the pork was examined by principal component analysis and electronic nose consisting of six metal oxide sensors. As a pork was cooked with 30g Jubak, ratio of resistance was increased. This condition removed unpleasant smell of pork. Effect of the pork with Jubak is better the end location than middle of pork. Also, first principal component score increased as the pork cooking time was increased. In the texture properties, hardness, chewiness, gumminess, and springness of the pork with 30g Jubak were significantly lower than others processed in this study. With sensory evaluation, the pork with 30g Jubak obtained the best score in taste, texture and overall acceptability. It could be concluded that the pork(400g) with 30g Jubak reduces the pork odor, increase the tenderness and improve the flavor and taste of pork.
