Surface and bottom water samples were collected from 10 stations located in the coastal area of Tongyong in April, August and October 2000. Distribution of heterotrophic bacteria, coliform bacteria and fungi in the sea water samples was investigated by measuring the comrresponding viable cell number according to the plate counting method. Heterotrophic bacteria in the surface water counted 3.1×10 exp∼4.0×10 exp (3) cfu ml^1, 2.7×10 exp∼1.2×10 exp (5) cfu ml^-1 and 1.3×10 exp (2)∼7.2×10 exp (2) cfu ml^1 in April, August and October, respectively. The cell number of coliform bacteria in the surface water amounted to 0∼15×10 exp (1) cfu ml^-1, 3.5×10 exp (1)∼5.2×10 exp (3) cfu ml^-1 and 0∼1.8×10 exp (2) cfu ml^-1 in April, August and October, respectively. As for fungi, the cell number in the surface water was 0∼3.0×10 exp (1) propagules ml^-1, 3.0×10 exp (1)∼8.0×10 exp (1) propagules ml^-1 and 0∼2.2×10 exp (1) propagules ml^-1 in April, August and October respectively. The surface water samples from the station 3 in August were added with feed staffs for fish as much as 0.01gl^-1, 0.1gl^-1 and 1gl^-1 and cultured at 5℃, 15℃, 25℃ and 35℃. Microbial cells were not isolated at all when the culturing temperature was 5℃. However, the microbial cell number increased significantly in all the surface water samples containing 1gl^-1 of the feed stuffs when cultured at 15℃, 25℃ and 35℃.

국내 중증 만성정신질환자 수를 추정하기 위하여 일 농촌 및 대도시 지역의 지역의료보험 및 의료보호 대상자 중 1993년 1년간 의료기관에서 정신증 상병(ICD-9 code 상 290-299) 및 알콜 남용/중독, 성격장애 및 정신박약 진단하에 치료를 받은 적이 있는 사람에 대해 설문조사를 실시하였다. 연구자들이 개발한 진단도구를 이용하여 진단을 평가하고, Strauss-Carpenter scale 등을 이용하여 기능 장애를 평가하고 유병기간 등을 조사하였다. 결과를 요약하면 다음과 같다. 1) 진단평가상 정신분열병군(61.1%)이 가장 많았으며, 정동장애군(23.7%), 알콜장애군(11.2%), 기질성 정신장애군(4.0%)의 순서이었다. 2) 직업활동정도는 진단군별로 차이가 많았다. 지난 1년간 직업활동이 6개월 미만이거나 전혀 없는 환자 비율이 정신분열병군은 67.2%, 알콜장애군 52.0%, 정동장애20.8%의 순으로 정신분열병군이 가장 불량하였다. 3) 사회활동도 진단군별로 차이가 많아서 지난 1년간 의도적, 사회활동이 없는 비율이 정신분열병군이 가장 높았고(72.3%), 알콜장애군(32.0%), 정동장애군(20.7%)의 순이었다. 4) 국내 의료보험 및 사회복지시설 이용 자료 등을 토대로 본 조사 결과를 적용한 결과 국내중증 만성 정신질환자의 수는 약 8만 7천명으로 추산되었다. Objectives: The purpose of this study was to estimate the number of serious and persistent mentally ill patients in Korea. Methods : Study populations were recruited from medical insurance data of two district areas ; one rural and the other urban areas. Subject were all mentally ill who had ever visited any hospital in 1993 and were diagnosed as having psychosis, personality disorder and drug abuse. We conducted a home visiting survey applying semi-structured diagnostic interview, assessing the level of social adjustment with Strauss-Carpenter Scale, and past psychiatric history by the trained researchers, in October and November,1994. Results : According to diagnostic assessment schizophrenic patients constituted the major portion(61.1%) of study subjects. The distribution of occupational functions and social contacts was variable according to diagnosis. Most schizophrenic patients were unemployed or worked less than 6 months in the previous year(67.2%), and showed poor social contact(72.3%). But affective disorder patients were relatively independent in job maintenance and social relationship. Alcoholic patients lay between those of schizophrenic and affective disorder groups. It was estimated that about 87,000 adult Koreans were suffering from chronic mental disorders which seriously interfere with their daily life. Conclusions : Serious and persistent mentally ill patients were common in Korea. Community support program should be provided for them.

The graft polymerization of 2-Hydroxyethylmethacrylate (HEMA) and Vinyltriethoxysilane (VTES) onto Styrene-isoprene-styrene block copolymer (SIS) was carried out in toluene, with radical initiators such as benzoyl peroxide(BPO) and α, α`-Azobisisobutyronitrile(AIBN) under nitrogen atmosphere. The degree of grafting was increased with the increases of the reaction temperature and reaction time. The efficiency of BPO was superior to that of AIBN. The mechanical properties and molecular weight of graft products were measured and the applicability as a adhesive of plasticized PVC leather was examined. The hardness and the molecular weight of graft products was increased with the increases of the degree of grafting, but elongation at break was decreased with the increases of one. And the tensile strength was maximum at the degree of grafting of about 6.5%. It was found that a toluene solution of graft products was confirmed to be an effective hot melt adhesive for the bond of plasticized PVC leather.

This study was conducted to examine middleㆍhigh school 720 students in seven regions of middleㆍsmall city and town, Myon for 2 months from March 2 through April 30, 2002 in order to realize a side of school health education in middleㆍhigh school and health education need as well as health education specialist in school in the future. The results of this study can be summarized as follows. 1. Health condition is now 'normal' is 51.0%, 'good' is 45.0%, 'not good' is 4.1% and health condition of children is good as much as education level of mother is higher. 2. Experience to learn health education in school for one year recently is 'no' is 39.6%, 'don't know' is 32.6%, 'yes' is 27.8% and it represents health education in school doesn't work well and experience to learn health education is lower and lower in town and Myon. 3. Health education ways to work in school now are 'Movie, Video, Slide' is 40.7%, 'education as groups of nurse-teacher' is 38.6%, 'to distribute health education material and book' is 7.7%, 'education by setting an example' is 3.4%, 'the others' is 9.7%. 4. Time of appropriate health education for one time is 'about a hour' is 56.7%, 'about 30 minute' is 33.8%, 'about two hour' is 7.6%, it represents this situation is because of what students' time is lack and burden about a curriculum in an education administratin and school classed of a focused school score. 5. The average score of satisfaction of health education in school is 16.99±0.58, 'men' is 1.79±0.60, 'women' is 1.61±0.55 as the distinction of sex, satisfaction level of men is higher than women. 6. Learning route about health information is 'through mass media' is 59.9%. 'through family, friend' is 15.0% 'health education lecture' is 7.2%, 'printing media' is 6.1%, 'medical institution' is 5.6%, 'the others' is 5.1%, 'public health center' is 1.0%, 'through mass media' is the highest percent as each 59.1% and 60.6% in all of men and women. 7. The most efficient education way of health education is 'movie, video, slide' is 32.6%, 'health education specialist who works school' is 21.9%, 'school health education by nurse-teacher' is 16.0%, 'way through mass communication' is 11.6%. 8. The appropriate health education specialist in the future is 'health education specialist who has qualifications' is the highest as 64.5%, 'nurse-teacher' is 12.4%, 'medical personnel(doctor, a physician of oriental medicine etc.,)' is 11.0%, 'staff in public health center' is 7.2%, people in other regions(health and medical professor etc.,) is 7.0%, it represents school health education is not actual and is formal now in second hand. 9. The most necessary health education program is 'program of stress solution' is the highest as 24.9%, 'program of no smoking' is 22.7%, 'sexual education program' is 19.8%, 'school violence program' is 8.8%, 'isolate from their friends prevention program' is 8.0%, solution program of stress which gives student by school score was very necessary. Therefore, school health education is formal and inefficient because school education focuses on an entrance exam, so middleㆍhigh school students decrease concern and interest about health education. Furthermore, reliance is gotten down about nurse-teacher who takes charge of school health, a charged person of school health education wants more chargeable health education staff. And a solution program of stress that gives students by school score was very necessary. According to active concern and planned, systematic school health education is necessary to give right health knowledge, health maintenanceㆍpromotion and setting of appropriate health education specialist is very urgent.

김성용,남충현,주종우,채만규,백무준,이문수,김형철,안현철,김홍수,김창진,김창호 순천향의학연구소 2001 Journal of Soonchunhyang Medical Science Vol.7 No.1

Purpose: Angiogenesis is important for the proliferation and the metastasis of solid tumors. The growth of a solid tumor is widely recognized to depend on the process of neovascularrozation. Without angiogenesis, tumors cease to grow beyond even a few milimeters in diameter. It has been shown that tumor vascular density is an independent prognostic marker in several types of human tumors and is known to correlate with poor prognosis. To date, many angiogenic factors have been identified, such as transforming growth factor-α(TGF-α), transforming growth factor-β(TGF-β), fibroblast growth factor family(FGF), vascular endothelial growth factor(VEGF), platelet derived endothelial cell growth factor(PD-ECGF), tumor necrosis factor-α(TNF-α), and angiogenin. Hepatocellular carcinoma(HCC) is the second most common tumor in Korean males and is known as a typical hypervascular tumor with frequent portal vein invastion. The authors identified the expreesion of VEGF, TGF-β1, and b-FGF in HCC specimens and evaluated the relationship between these growth factors and the clinicopathologic characteristics of HCC. Method: We reviewed the medical records of 30 patients who were diagnosed as hepatocellular carinoma treated with hepatic resection between January 1994 and December 1998 in Soonchunhyang University Chunan Hospital. The selection of the cases was decided according to the condition of paraffin block fixation. The prognostic factors such as age, sex, tumor size, concentration of serum α-fetoprotein, presence of liver cirrhosis, presence of tumor emboli in portal vein, TMN stage, amount of transfusion during the operation, hepatitis B virus(HBV) infection, and Edmonson-Steiner(E-S) grade were investigated. Relationship between the prognostic factors and the immunopathologic expression of the TGF-β1, b-FGF, and VEGF was examined. Result: Thirty patients (24 males, 6 females) were included in the current study. The patient's mean age was 50.6 years and the age ranged from 36 to 65 years. The mean size of the tumor was found to be 5.2cm. All the patients were follewed up for 7 to 63 months. Child's classification A patients were 23(76.7%)cases, B patients were 7(23.3%)cases, and C was none. Immunohistochemical staining of HCC tumor mass in VEGF expression patients were 17(56.7%), b-FGF expression patients were 10(33.3%), and TGF-β1 expression patients were 10(33.3%). VEGF expression or more than one positive expression among the three factors correlated with tumor size and the stage of HCC but did not correlated with other clinicopathological characteristics. TGF-β1 and b-FGF did not correlate with any clinicopathological characteristics. Conclusion: The results suggest that the expression of VEGF or more than one positive expression among the three factors in HCC cells may be a significant prognostic factor of HCC.
