In the view of the results investigated the effect of air pollutants that is emitted from a new generator facilities, the total estimated concentration which is the summation of a contributional concentration and observational concentration is much less than that of atmospheric environment criterion for the air pollutants. So we can predict that the operation of the new generator facilities with mitigation equipment don't seriously affect around environment. At the same time, we compared the contributional concentration of before mitigation equipment with that of after it to examine the decreasing amount due to mitigation equipment. The result showed that the concentration of SO2, NO2 and PM-10 is reduced to 25%, 30% and 26% of original value, respectively.

Hepatocellular carcinoma(HCC) is the second most common cause of cancer death in Korea. Generally, HCC was unresectable due to the frequently associated cirrhosis and advanced stage of tumor. As a palliative therapy of HCC, transcatheter arterial chemoembolization(TACE) was a proven effective mean of treating inoperable HCC. We have analyzed the effectiveness of TACE in inoperable HCC. TACE was performed in 20 patients from January in 1990 to May in 1993 at Chung Nam National University Hospital with the infusion of mixture of Lipiodol and Adriamycin. We analyzed the survival rates of the TACE group and the control group who received no specific treatment. The results were follows ; 1) The survival rate was significantly higher in TACE group than control group(p<0.01). The survival rate at the end sixth months and one year were 62.8% and 40.0% in TACE group, 26.6% and 0% in control group, respectively. 2) A declining level of AFP(Alph-fetoprotein) was shown in 8 among 10 cases who underwent TACE/and was higher than 500 ng/ml in pre-TACE level(p<0.01) and also tumor size was decreased in 7 among 20 cases who underwent TACE. 3) Side effects were fever(80.0%), and upper abdominal pain(75.0%) in TACE group but improved within 7 days after TACE and impairment of liver function was developed in most patients(TACE group) but improved within 2 weeks after TACE. As a palliative therapy of HCC, TACE is an effective and useful modality in treating and prolonging the survival time of patients with unresectable hepatocellular carcinoma.

To evaluate the safety and efficacy of Pd withdrawal followed by recombinant alpha- Interferon 2b therapy. Nine patients were given a single daily subcutaneous injection of ^α-Interferon at a dose of 3 x 10 exp(6) units/day for first weeks and thrice weekly for next 15 weeks (maintenance) after pd tappered over 6 weeks. To evaluate the efficacy of therapy, we measured serum aminotransferase activities monthly during and after therapy, and also measured serm HBsAg, HBeAg and DNA probe before and after therapy. To evaluate the safety of therapy, all patients checked peripheral blood WBC, Hemoglobin, Platelet, BUN and Creatinine. The results were as follows : 1. In control group, the normalization of s-AST & ALT level, negative seroconversion of DNA probe & HBeAg were observed in 1/12(8%) & 7/10(17%), 0/10(0%) & 0/12(0%) at 6 months later, and maintained response in 1/11(9%) & 1/11(9%), 2/9(22%) & 2/11(18%) until 1 years later. 2. In treatment group, Serum AST and ALT returned to normal in 8/9 & 8/9 cases (89%) after 1 montns Tx. (mean serum AST : 33±8, ALT : 34±12 IU/ml) and maintained to normal response in 5/9(56%) & 6/9 cases(67%)after 6 months Tx. (mean s-AST : 55±43, ALT : 66±84 IU/ml), 3/9(33%) & 4/9 cases(44%) after 1 years Tx. It was statistically significant reponse except s-AST of after 1 years Tx. 3. In treatment group, s- HBeAg returned to normal in 3/9 cases(33%) after 1 months Tx., and maintained to normal response in 1/7 & 1/4 cases among follow up patients in after 6 & 12 months Tx. Serm DNA probe level were observed significantly negative seroconversion in 8/9 cases(89%) after 1 months Tx. (p<0.003), and maintained to negative response in 2/6 & 1/3 cases after 6 & 12 months Tx. 4. Serum AST, ALT, HBeAg and DNA probe were not significantly correlated with therapeutic response in relation to histologic diagnosis. 5. Fever and myalgia were noted in 9(100%) & 6(67%) cases. Headache, mild hair loss, anorexia, nausea, facial flushing & diarrhea were noted in few cases. Peripheral WBC(3cases) & platelet counts(3cases) were decreased transiently. This study shows that Pd withdrawal followed by recombinant alpha Interferon 2b therapy may be safe and effective in decrease the level of s-DNA probe, transaminase activity, loss of HBeAg and less adverse effect of clinical and hematologic examinations in patients with CAH type B. But it was necessary for study with large number of patients, more prolonged follow up duration and more strict control study.

For the purpose of prediction air quality in Kimhae area, ISC3 and UAM were used. As the study area is located in a coastal area, the atmospheric flow is strong1y affected by the sea breeze. The air quality model results show that the dirunal variation pattern of pollutants is consistent with observed spatial and temporal features, as a whole.

The differences of the liver scintigraphic features between postnecrotic and nonpostnecrotic liver cirrhosis were studied for 69 patients. Degrees of mottling and splenomegaly were no different between two groups but shrinked form was more frequent finding in postnecrotic type(23:10), and normal shape & enlarged left lobe with shrinked right lobe were relatively dominant in non-postnecrotic group(15:6, 10:2). Grade of extrahepatic uptake of ^99mTc-tin colloid was significantly higher in Child-Pugh B & C group than A group(p<0.05), but there was no difference between postnecrotic and non-postnecrotic groups. These will be important results on the dicision for the presence of cirrhosis according to the variable causes.

In order to investigate the variation of meteological factors induced by construction of dam, the prediction model, WQRRS, is used. As a result, the effect of Dam construction showed that the amount of evaporation increases because of broad water surface area. Therefore, nighttime relative humidity is raised, and annual foggy days are increased more than 7days and sunshine hours are decreased.

Omental infarction, the end result of impaired perfusion to the greater omentum, is a rare benign self-limiting clinical entity. The main clinical symptom is non-specific localized abdominal pain with a moderately raised white blood cell and erythrocyte sedimentation rate. These findings often mimic an abdominal surgical emergency. This condition is often misdiagnosed as acute appendicitis or cholecystitis. The characteristic feature of CT scan and ultrasonography provide non-invasive diagnosis in most patients with omental infarction. We report a case of patient whose CT scan showed the characteristic finding of omental infarction. The patient was improved spontaneously only with conservative care.

PT-PCR법을 이용하여, 우리 나라 동해안의 양식 넙치에서 VHSV를 검출하였으며 5개의 VHSV isolates의 N gene과 G gene을 sequencing하였다. Phylogenetic analysis를 실시하여 이들 VHSV isolates와 지리적 분리 유래가 다른 VHSV strains간의 유전학적 상관관계를 조사하였다. 일반적으로 VHSV strains의 유전형은 그 지리적 분리 유래에 따라 American type (Genogroup Ⅰ), British Isles type (Genogroup Ⅱ), European type (Genogroup Ⅲ)으로 구분할 수 있으며, 본 연구에서는 우리 나라 양식 넙치에서 분리한 5개의 Korean isolates는 모두 Genogroup Ⅰ에 속하며, 일본의 Obama25 type과 유사하다는 것을 밝혔다. RT-PCR method was applied to detect and clone the nucleocapsid protein (N) gene and glycoprotein (G) gene for sequencing 5 Korean VHSV isolated from cultured olive flounder, Paralichthys olivaceus. Phylogenetic analysis was performed to investigate their relationship with the VHSV strains described previously and isolated from different geographical area. Generally, VHSV strains were separated phylogenetically according to the major geographical area of isolation: Genogroup Ⅰ(American type), Genogroup Ⅱ (British Isles) and Genogroup Ⅲ (European type). This study revealed that all 5 Korean VHSV isolated were belonged to Genogroup Ⅰ and closely related to Japanese Obama25 type.

The six kinds of natural factors(It refers to wind, cold, summer-heat, dampness, dryness and fire.) is constantly moving to maintain the balance of whole climate of one year. Four seasons are the largest mediation of whole climate of one year. The cold and the heat have the relationship of mutual intervention. The dampness and the dryness have it also. In this process they raise various climate appearance. And that various climate appearance influence the whole lives on the earth. This paper is concerned with the classification of them.
