For studying this project, we selected a 2-storied detached house as a sample which was constructed in July 1976, the last year of the 3rd 5-years economic and social development plan and also the middle year between the years of the 1st oil crisis and the 2nd oil crisis, located In Gayang-dong, Daejeon City. The contents and scope of this project was to produce retrofit measures by theoretically analyzing the building energy use between both of pre-retrofit and post-retrofit conditions of this sample house, and to compare and analyze the predicated data with experimented data under post - retrofit condition. It is suggested in this report that we have to develop rational and practical retrofit measures for energy conservations in existing residences.

Standard Building Operation Conditions(SBOC) is to describe typical conditions under which a building would operate during the coulee of a day In order to develop SBOC profiles for office building, we surveyed the operating conditions of randomly selected 20 existing office buildings in Seoul by means of enquetes, and made SBOC profiles. SBOC profiles consist of human occupancy profile, light ins usage profile, system schedule and domestic hot water profile etc. SBOC profiles will be used as input data of DOE-2 computer program to estimate DER(Design Energy Requirements) and to develop EBL (Energy Budget Level), SBOC profiles are not meant to be exact description of how a building will actually be used by its respective users. Rather they are intended to be reasonable typical project ions of how buildings might be used.

In this study, the thermal environment of a certain building was investigated by using of concerned equipments and enquete sheets. The measured items were temperature, humidity, air flow and radiant heat, and thermal responses for the occupants were checked also, which are oriented to be used as basic data for environmental design. The results of this study are as followed. 1. The optimal room temperature was $24\~26.5^{\circ}C$ DBT in cooling season. 2. Under the condition from $50\%\;to\;70\%$ of relative humidity, the difference of relative humidity did not impact upon the feeling temperature. 3. In cooling season, the average clothing factor of occupants was 0.34 clo ; 0.49 clo for men and 0.25 clo for women. 4. The average working factor of occupants was $1.1\~1.3\;Met$ in that cooling season.

The organization of eukayotic chromatin into specific conformation that are associated with transcription, replication, reapir and other nuclear processes are achieved via a series of DNA-protein interaction. These interactions are mediated by a range of DNA-binding domains such as SAP domain et at. By searching S. pombe genomic DNA database, we have found a gene named SAPuvs (SAP UV Sensitive) whose amino acid sequence is in part similar to SAP domain of Arabidopsis poly (ADP-ribose) polymerase and Ku7O. Knock-out cell of S. pombe SAPuvs gene was constructed using Ura4 as a selection marker. Survival analysis of knock-out cell indicated that treatment with UV significantly reduces the survival compared to wild type cell. Potentiation of MMS-induced cytotoxicity by 3AB post-treatment was observed in wild type cells, but not in knock-out cells. These data suggested that the protein encoded by SAPuvs gene is associated with chromatin reorganization during DNA repair.

The goal of this study was to identify relationships between the composition of sulfate reducing bacterial assemblages and terminal restriction fragment length polymorphism (T-RFLP) patterns in rice paddy and dry farming soils. Samples of organic farming soils, conventional farming soils, and dry field farming soils were collected in August and November. Analyses of the soil chemical composition revealed similar total nitrogen, total carbon and total inorganic phosphorus levels; however, the moisture content and total carbon were higher than in the other soils in both August and November, respectively. Sulfate reducing bacteria utilizing lactic acid were more widely distributed than those that used acetic acid, and the number of sulfate reducing bacteria in organic farming soil was most abundant. Phylogenetic analysis based on 181 clones revealed that most showed low similarity with cultured sulfate reducing bacteria, but more than 90% similarity with an uncultured sulfate reducing bacteria isolated from the environment. T-RFLP analysis revealed that fragments of 91, 357, 395, and 474 bp were most common, and the community structure of sulfate reducing bacteria changed seasonally.

Coronaviridae에 속하는 transmissible gastroenteritis virus(TGEV)와 porcine epidemic diarrhea virus(PEDV)를 specific하게 detection할 수 있는 방법을 개발하고자 본 연구를 수행하였다. 두 바이러스 모두 RNA 바이러스이기 때문에 reverse transcription-polymerase chain reaction(RT-PCR)으로 nucleocapsid(N) protein gene의 cDNA를 증폭시켰다. SmaI으로 처리한 pTZ19R에 ligation시킨 후 염기서열을 밝히고자 sequencing하였다. 각각의 prototype virus와 비교하여 상동성을 밝혔다. 두 바이러스에 대한 cDNA probe를 제작하여 Southern blot hybridization을 실시하였다. TGEV의 경우 백신주인 P45와 병독주인 Miller strain을 사용하였다. cDNA를 증폭시키기 위해 N1/N1R과 N2/N2R 두 가지 primer를 이용한 결과, N1/N1R primer의 경우 586bp 크기의 PCR product를 얻을 수 있었고, N2/N2R primers로 582bp의 cDNA를 증폭시킬 수 있었다. PEDV 실험을 위하여 PED 임상 증상을 나타내는 분변을 이용하여 RT-PCR을 실시하였다. P2/P2R primer로 753bp의 PCR product를 얻을 수 있었다. TGEV의 두 가지 strain의 N protein gene을 sequencing하여 prototype인 Purdue strain과 염기서열 상동성을 조사한 결과, 97%이상의 높은 homology를 나타내었다. PED-V 역시 N protein gene을 sequencing하여 CV777과 염기서열 상동성을 조사한 결과 97%이상의 homology로 PEDV임을 알 수 있었다. TGEV와 PEDV의 염기서열을 비교한 결과 29%의 낮은 homology를 관찰할 수 있었다. 두 가지 바이러스의 N protein gene에 대한 cDNA probe를 제작하여 Southern blot hybridization을 한 결과, 각 바이러스에 매우 특이적 반응을 나타내었다.

A various building certification systems are being enforced in Korea. However, the enforcement of many building certification systems has brought on the concerned people's confusion and the operation of various building certification systems which have similar assesment items causes much time and economical losses. Therefore, in this paper, the features of the GBCS(Green Building Certification System), Housing Performance Indication System, Building Energy Rating System, and Green Home Standard and Performance Evaluation System are compared and the correlations among each building certification system are analysed. As a result, it is presented that a considerable number of assessment items were so similar and identical that integration of building certification systems is needed for effective operation of these systems.

Objective : Many methods have been used for treatment of facial nerve paralysis. The purpose of this study was to evaluate the clinical difference between acupuncture therapy and acupuncture-oriental herb medicine therapy. Materials and Methods : From 05-01-2000 to 01-30-2001, 46 facial paralysis patients who were hospitalzed and treated more than five times at the Department of Acupuncture & Moxibustion of Dongguk University Bundang Oriental Medical Hospital were selected for two group. One group(A group) was treated by acupuncture therapy, the other group(B group) was treated by acupuncture and oriental herb medicine therapy. A group was composed of 15 patients and B group was 31 patients. Results and Conclusion : As the results of study, both acupuncture therapy and acupunture-oriental herb medicine therapy were usable for facial nerve paralysis treatment. But, we could not discover any available difference between acupuncture therapy group and acupuncture-oriental herb medicine therapy group.

This study was designed and undertaken to identify objectively the degree and relationship of anxiety, depression which are chief essential elements of emotional status in Stroke medical examination patients. The subjects in this study were 58 Stroke medical examination patients and 58 Non-Stroke medical examination patients, and for the assessment of anxiety, depression. We used State-Trait Anxiety Inventory (STAI), Zung's Self-Rating Depression Scale(SDS). The results of this study are as follows : 1. There were significant, differences in the 16 items of State anxiety scale among 20 items and the 14 items of Trait anxiety scale among 20 items between Stroke medical examination patients and the control group(p<0.05 respectively). 2. There were significant differences in the 14 items of SDS among 20 items between Stroke medical examination patients and the control group(p<0.05 respectively). 3. There were significant differences in the mean scores of STAI and SDS between Stroke medical examination patients and the control group(p<0.001 respectively). 4. There were no significant relationships between State anxiety & Trait anxiety, State anxiety & Depression, Trait anxiety & Depression in the Stroke medical examination patients.
