한강 수계 분지 내의 하천수 (지표수)와 서울 지역 지핫의 화학적 특성 규명과 용존 이온종의 기원을 연구하기 위해 1996년 3월-4월 동안 하천수 시료 60개에 대하여, pH, TDS 등과 용존이온의 화학분석을 실시하였다. 남한강과 북한강 하천수의 화학성분은 주로 수계분지 지역에 분포하는 암석에 의해 영향을 받고 있으며, 한강본류의 하천수는 인위적인 오염에 의한 영향이 크게 나타나고 있다. 즉, 남한강은 상류지역에 분포하는 탄산염암, 탄광 및 금속광산 폐수등에서 용출된 Ca(), Mg(), HCO(), SO() 등이 현저하며 북한강은 화강암질암의 풍화 산물인 K(), Na(), Ca()등의 이온종이 특징적이다. 한편 양수리에서 상기 2개 하천이 합류하여 서울 도심을 지나는 한강 본류는 SO(), NO(), PO(), Cl()등 생활하수 오염의 영향이 현저하게 나타나고 있다. 한강 본류로 유입되는 서울 지역의 왕숙천, 탄천, 중랑천, 안양천의 4개의 지천은 NO(), Cl(), PO(), SO(), Mn등 인위적인 오염현상이 크게 나타나고 있다. 한강 하천수의 화학 성분의 군집, 요인 및 회귀 분석 결과, 전체 자료 분산은 오염 인자에 의한 분산이 약 79%, 지질과의 물-암석 반응에 의한 분산이 약 7%이다. 남한강과 북한강의 합류 지점에서의 Cl에 대한 혼합 비율은 약 60:40이다. 1981년 분석 자료와 1996년 자료의 비교에서 암석 풍화에 의한 1차적 용존 성분인 Ca(), Mg(), HCO()등은 변화가 적으나 Na(), NO(), PO(), SO()등 인위적 오염원의 성분은 크게 증가하는 경향이 있다. To investigate geochemical characteristics and the sources of the dissolved ion species in the river water in the Han river drainage basin, samples were collected at 60 sites from the Han river drainage basin. The data for pH, conductivity, TDS(total dissolved solid), temperature, and concentrations of dissolved ions were obtained as follows:(1) The geochemical characteristics of the surface water in the South and North Han river drainage basins are mainly controlled by bed rock geology in the drainager basin and in the main stream of the Han river considerably affected by anthropogenic pollution. The South Han river water samples have high concentration of Ca() (ave. 15.42ppm), Mg()(ave. 2.74 ppm), HCO()(ave 51.9ppm), which evidently indicates that the bed rock geology in a limestone area mainly controls the surface water chemistry. The concentration of SO() is remarkably high(SHr10-2:129.9ppm) because of acid mine drainage from the metal and coal mines in the upper reaches of the South Han river. (2)The South Han river and the North Han river join the Han river in the Yangsuri, Kyounggido and flow through Seoul metropolitan city. The mixing ratio is about 60:40 at the meeting point(sample number HR10). (3)The result of factor analysis suggests that the pollution factor accounts for about 79% and the bed rock type factor accounts for about 7% of the data variation. This means that the geochemical characteristics of the Han river water mainly controlled by anthropogenic pollution in the South Han river and main stream of the Han river drainage basin. (4)The chmical data for four tributaries such as the Wangsukcheon, the Tancheon, the Zungrangcheon, and the Anyangcheon show that the concentration of pollution elements such as NO(), Cl(), PO(), SO() and Mn are high due to municipal waste disposal.

To obtain the prevalence rate of health related symptoms of white collar workers who were not exposed to hazardous agent and to investigate the relationship between subjective symptoms & health related variables, 11,266 subjects who were employed for government organization & private educational institute in Seoul, Chungnam, Kyungpook area were studied in order to provide basic information for the health management of white collar workers. All th subjects visited hospitals to take biannual health examination provided Medical Insurance Association for the purpose of screening of several important adult disease. Todai Health Index(THI) questionnaire which is modified questionnaire of CMI made by Todai was selected for the questionnaire form of this study. During hospital visit for health examination, Todai Health Index questionnaire of 88 questions were filled up by the subjects themselves and confirmed by medical doctor. Major findings obtained were as follows: 1. The abnormal rate of screening test was 22.7% in male, 8.5% in female, and 19.2% in total subjects. The prevalence rate of disease was 13.2% in male, 4.9% in female & 10.9% in total subjects. 2. The prevalence rate of all diseases increased by age and th prevalence rate of male subjects were higher than female subjects in all age categories except that of the anemic disease. 3. While highest prevalence rate in all subjects was observed in cardiovascular disease(4.8%), the prevalence rate were 3.4% in liver disease, 2.0% in diabetic disease, 1.9% in pulmonary tuberculosis & chest disease, 0.5% in kidney disease and 0.4% anemic disease. Liver disease was more frequent in age group of below 29 years old and age group of 30-39 years old, but in older age groups(40-49 years old, above 50 years), cardiovascular disease was most frequent. 4. The highest mean score of THI symptom category was mental instability and the lowest one was skin & anus symptoms. The most frequent symptom of THI was "think a lot before action" in nervousness symptom category and mean scores of the female subjects in all symptom category were higher that those of male subjects. 5. In symptoms and signs of recent 3 months, the most frequent symptom and sign was "generalized fatigue" and mean score of it was 1.85. Multiple comparison analysis of health related factors revealed that "illness in health status" was the highest score(23.54) in male and sometimes drink & drunken in alcohol intake was th highest score(26.13) in female. 6. In multiple comparison analysis, health related factors such as health status, health management, diet habit, taste character, vegetable intake, coffee & beverage, alcohol intake were found to be associated with th overall THI symptom category in both sex and age and smoking in male, type of job in female were associated THI symptom category. 7. In stepwise multiple regression analysis of mean score of THI symptom category(dependent variable) and health related factors(independent variables), the variables of health health status, taste character and alcohol were contributed to THI symptom category in order and the highest correlation coefficient(r) was 0.4085 in male and 0.397 in female in health status of mental instability. 8. The significant health factors contribution to THI symptoms score in male subjects were, in multiple regression analysis with THI symptom category with dependent variable and health related factors with independent variables, health status, diet habit, alcohol intake, taste character, final diagnosis, coffe & beverage, type of job, age, smoking, health management, meat intake and in female were health status, type of job, diet habit alcohol intake, coffee & beverage consumption, screening test, age, health management. The most significant contribution factor among health related variables was health status in over all THI symptom category.

Background and objectives : The long-term survival in patients with non-Hodgkin's lymphoma (NHL) after conventional dose chemotherapy is about 35% and the rest of the patients tend to have relapse. So, in relapsed or refractory NHL, we compared the outcome of patients undergoing high-dose chemotherapy with autologous peripheral blood stem cell transplantation(APBSCT) with only salvage chemotherapy of cisplatin, dexamethasone, mitoxantrone, and etoposide(CDME). Materials and methods : From June 1993 to December 1999, 25 patients with relapsed or resistant NHL were treated with CDME regimen as salvage chemotherapy. Twelve patients were received four cycles of CDME chemotherapy, and 13 patients were received high-dose chemotherapy with APBSCT following two cycles of CDME chemotherapy. Results : The median follow-up duration was 12.8 months(range:4-68). The overall response rate was 41.7% (complete response rate 25%, partial response rate 16.7%) in 12 patients with CDME only. Thirteen patients who were treated with high-dose chemotherapy with APBSCT achieved 61.5% complete response rate and 15.4% partial response rate, with an overall response rate of 76.9%. The estimated 3-year progression-free survival rate was significantly higher among patients who received high-dose therapy than patients who received CDME only(41.5% vs 20.0%, p<0.05). And, 3-year overall survival rate was significantly higher among patients who received high-dose therapy(51.3% vs 25.0%, p <0.05). Conclusions : In relapsed or refractory NHL, CDME chemotherapy is an effective salvage chemotherapy and allow peripheral blood stem cell collection. Also, high-dose chemotherapy with APBSCT following CDME is superior to CDME salvage chemotherapy only.

This study aimed to propose a program of support for establishing the identity of children from multicultural families on the basis of the basic principles of Phinney's (1989) stages to establish identity. Based on the principle that states the identity is established through unexamined identify, identity search and identity determination (resolution) stages, a support program for establishing the identity of children from multicultural families was presented. These 3-stage progression can be applied to human developmental stages of infant, childhood, adolescence and adulthood. In the stage of unexamined identity, a child care assistance program and a support program for verbal communications with a married immigrant mother or father are needed for close child-parent relationship. The stage of identity search requires support programs for helping adolescents from multicultural families to overcome self-identity crisis and resolve psychological conflicts in addition to bilingual (linguistic) support program. In the stage of identity determination (resolution), an employment and sociality cultivating empowerment program for establishing a cultural identity as a member of society in the process of forming a relationship with social system was presented.

한국탁,박혜진,이규승,김일중,김규섭,조성민 한국환경농학회 2002 한국환경농학회지 Vol.21 No.4

대전시 노은 도매 시장에 서 채취한 과실류와 6종의 농약잔류량을 조사한 후 이에 대한 위해성 평가를 실시하였다. 전체 120건 분석시료 중 70.8%가 농약 성분이 검출되었고 그중 1.67%가 잔류허용기준치을 초과하여 검출되었다. 검출 비율이 높은 시료는 사과, 복숭아, 포도 등이었다. 검출된 성분에서 살충제는 유기인계, 합성 pyrethroid계, 유기염소계가 비슷한 비율로 검출되었고, 살균제에서는 특히 procymidone(dicarboximide계)과 chlorothalonil(유기염소계)의 검출비율이 높았다. 검출빈도가 높은 성분은 chlorothalonil, chlorpyrifos, fenvalerate, procymidone, deltamethrin, EPN의 순이었다. 위해성을 평가하기 위해서 각 농작물에 대한 농약의 추정섭취량과 ADI를 비교한 결과, 추정섭취량의 비율이 1.221%이하로 나타나 그 영향이 매우 낮은 것으로 판단되었다. 이것은 농약 잔류 허용기준치를 초과한 농작물인 복숭아에서 chlorothalonil, EPN에 대해서도 동일한 결과를 나타내었다. Pesticide residues in some fruits collected at Noeun wholesale market, Daejeon were surveyed and assessed its risk. In 120 samples, the detection rate of pesticide was 70.8% and the rate exceed MRL was 1.67%. Highly detection rate of commodities was apple, peach and grape. Organophosphorus, organochlorine and pyrethroid insecticide were found with similar rate relatively, but most of fungicides were procymidone(dicarboximides) and chlorothalonil(organochlorine). The order of detected pesticide were chlorothalonil, chlorpyrifos, fenvalerate, procymidone, deltamethrin and EPN. In order to assess risk, estimated intake amount of each pesticide was compared to ADI. Although some peach were exceed MRL, the total amount and uptake pesticides was less than 1.22% comparing to ADI.

During the period from 1960s to 1970, the Korea's economy has recorded a rapied growth of average 7.8% per year, but such economic rapid growth disclosed economical interval appearence among regional areas. For the coming 1980s, economy policy will necessary a equilibrated industrialization strategy between regious to promote the export, getting out of the industrial policy and theory of disequlibrium growth that based on import substitute industry before in the direction to reduce the interval between regions. Through these studies, tried to gaind the basis theory of regional economy development and the political strategy theory, also we have concluded as follows as possible means to improve the regional economic policy instrument. 1.The equilibrium development of regional economy should be linking development between economic growth pole of advenced region and underdeveloped region, and it not only go through infrastructure investment by mutual adjustment between the measures and district, but also the enlargement of capital, labour power, the commodity market. 2.It should be enlarged the employed opportunity on the other except controlled area, and relatively the developed region, that is, the center of economic variation should be the core development or strategy for regional economy development. 3.Not only the growth pole formation should be used as a measures to promote the structural fluctuation at a rural community, but also industrial complex enlargement of other region should be made as a measure improvement policy industrial structure in the region.
