Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

박수정,주영미,김정락 인제대학교 1991 仁濟論叢 Vol.7 No.2

배양 근원세포 분화에 따른 세포융합에 직접적으로 관여하는 단백질을 찾기 위해 48 시간 배양한 근원세포를 항원으로 BALB/C mouse에 면역시켜 얻은 spleen cell과 myeloma cell(P3U-1)을 융합시켜 근원세포와 반응하는 항체를 분비하는 hybridoma를 얻었다. 세 차례 한계 희석 후 계대배양하여 분리한 clone들이 분비하는 항체를 근원세포 배양액에 첨가하여 근원세포의 융합을 억제하는 효과가 있는 단일클론항체인 MAb MII-3J3l을 얻었다. MAb MII-3J3l의 효과는 2 ㎍/ml의 농도에서 세포분열에 영향이 없이 근원세포의 융합을 완전히 억제하였으며 이 효과는 적어도 48 시간 지속되었고 항체를 제거할 경우 융합이 재개되어 가역적인 억제효과를 나타내었다. MAb MII-3J31이 인지하는 단백질은 38 kDa로 근원세포 표면을 trypsin 처리하였을 때 잘리워 나감으로 표면단백질로 추정된다. The present study describes the production of monoclonal antibodies against cultured chick myoblast to pursue a protein may play a critical function in muscle cell fusion. Among a panel of monoclonal antibodies, MAb MII-3J3l inhibits myoblast fusion completely, while cell growth proceeds normally and its effect is reversible. The antigen reactive with MAb MII-3J31 isolated by radioimmunoprecipitation and detected by immunoblot was found a 38 kDa protein. For trypsin-treated cell lost its antigenic determinant, the protein may be located in the cell surface.

Cerivastatin is effective and safe for patients with hypercholesterolemia who needs aggressive LDL cholesterol lowering.

한국인의 삭카린 섭취량 산정

박세미,이서래 이화여자대학교 생명과학연구소 1992 생명과학연구논문집 Vol.3 No.-

국내에서 유통되는 가공식품중 삭카린의 함량을 분석하였고, 이 자료와 삭카린 공급자료를 바탕으로 한국인의 1인당 1일 삭카린 섭취량을 추정하였다. 분석에 사용된 74개 시료중 60개에서 삭카린의 사용을 확인할 수 있었으며 검출 평균농도는 단무지 306ppm, 스낵과자 285ppm, 간장 153ppm, 빙과 51ppm, 유산균 음료 37ppm이었다. 허용기준에 대한 초과빈도를 보면 스낵과자가 시료의 70%에서 초과하였고, 허용기준에 대한 평균농도의 비율은 2.9배에 도달했으나 기타 식품에서는 그 기준을 초과하지 아니하였다. 1985년에서 1990년에 걸친 삭카린의 1인당 1일 평균섭취량은 소비자료에서 추정했을 경우 7~17mg, 공급자료에서 추정했을 경우 9~35mg이엇다. 이 수준은 미국, 일본의 경우보다 약간 많았으나, FAO/WHO에서 권고한 인체허용 1일 섭취량(ADI)의 11~22%수준이었다. 따라서 한국인에 대하여 삭카린의 안정성 문제는 현재와 같은 사용수준에서는 크게 걱정할 필요가 없는 것으로 판단된다. Out of 74 food samples including pickled radish, soy sauce, Lactobacilus drinks, frozen sweets and snack confections. 60 samples were found to contain saccharin. The contents of sacchrain in terms of maximum and positive mean were 541,306 ppm in pickled radish. 302, 153 ppm in soysauce. 66, 37 ppm in Lactobacillus drinks, 90,51 ppm in frozen sweets and 606,285 ppm in snack confections, respectively. Most food items did not exceed the tolerance limit of saccharin while 70% of snack confections exceeded the limit, the average concentration being 2.9 times of the limit. Total daily intake of saccharin by Korean population for the period of 1985~1990 was estimated to be 7~17mg/person from consumption data and 9~35mg/person from supply data. The intake level was 11~22% of acceptable daily intake for man (ADI) recommended by FAO/WHO whereas the level was slightly higher than that in USA or Japan. It is, therefore, judged that saccharin at the current pattern of usage will not exhibit any adverse effect on the safely of Korean population.

Background: With reports on the relation between smoking and depression appearing since 1980, it has become clear that depression is one of the psychodynamics of smoking, though there has been little or no progress made in the study of whether or not there is indeed a relation between depression and nicotine dependence. Purpose: The purpose of the study was to investigate the effects of depression on the amount and period of smoking and nicotine dependence among university man student smokers. Method: In periodical examination between 14 and 21, May, 2003, using 170 university male. The CES-D(Center for Epidemiologic Studies Depression) Scale and the FTQ(Fagerstrom Tolerance Qustionnaire) were utilized to measure the level of depression and nicotine dependency. The amount of smoking was calculated based on the number of cigarette used. Result: Results indicated that depression had something to do with amount of smoking. Nicotine dependence also was related to depression but total value was relatively low. finally the period of smoking had nothing to do with depression. Conclusion: The results of this study revealed that the amount of smoking of university man student smokers was very high. Both the amount of smoking and nicotine dependence were affected by levels of depression. Accordingly psychiatric nursing access such as emotional support is needed to manage depression and decrease smoking.

Background : Intravenous(Ⅳ) access is becoming an increasingly important part of health care today. The current drive for clinical effectiveness and cost-effective health care serves to increase the need for reliable vascular access. Venous access devices were developed to overcome problems associated with limited peripheral access and frequent venipuncture in patients with long-term therapy. Although the peripherally inserted central catheter(PICC) have become popular during recent years in USA, its procedure is rare in Korea. Purpose : The goal of this study was to analyze the PICC inserted patient data by Ⅳ CNS intervention. Method : A Total of 62 PICCs were inserted into 51 patients by the Ⅳ CNS during a 10-month period form November, 14, 2002, to October 2, 2W2. Data was obtained retrospectively through chart review. Result : The patient population included 34(54.8%) men and 28(45.2%) women, with a mean age 50.6 years. The main indication for PICC placement was to access vein in poor peripheral venous status(40.3%). The mean served interval for PICC insertions was 16.7 days(range, 2~61 days). The reasons for removal were completed therapy in 18 cases(29.0%), patient death in 13 cases(21.0%), and mechanical or functional PICC problem in 10cases(16.1%). The three PICCs removed for presumed infection, and one had only positive tip cultures(0.2%). Conclusion : PICCs are rapidly growing popularity and required an extended course of Ⅳ therapy.

In order to use leaf mustard Dolsan food preservative ingradient, acidity, antimicrobial activity and colors were investigated during pretreatment of leaf mustard Dolsan. pH was remarkably decreased after 8 hours to pretreatment(extracted on shaking) of leaf mustard Dolsan, and no changes were observed after that time. pH of leaf part was higher than stalk after 8 hours storage. Titratable acidity was opposite tendency to the pH, pH was gradually decreased than initial stage during pretreatment: of leaf mustard Dolsan at 30, 40 and 50℃. After 16 hours pretreatment, the higher pretreatment temperature was, the higher pH was, but after pretreatment for 48 hours, pH of sample pretreated at 50℃ was lower than that of sample pretreated at 40℃. Antimicrobial activity of leaf mustard Dolsan extract pretreated at 30℃ was the strongest of the samples pretreated at 30, 40 and 50℃, and that of stalk part was stronger than that of leaf part. L and b value in colors was gradually decreased, and a value was increased with the passage of pretreatment time. L and b value was higher in the order of samples pretreated at 40, 50 and 30℃, and the lower pretreatment temperature was, the higher a value was. L value of stalk part was higher than that of leaf part, but a and b value of of leaf part was higher than that of stalk part.

Apples were coated with various chitosan solutions (30 cps 1%, 30 cps 3%, 90 cps 0.5%, and 90 cps 2%) and changes in quality parameters such as weight loss, Hunter color values (L, a, and b), brix, pH, titrable acidity,and hardness were investigated during 70 day storage at room temperature. Weight loss of apples coated with 90 cps 2% chitosan was lower than those of other samples during storage. In color change, chitosan coating appeared to decrease red color and increase green color in apples. Brix of juices extracted from apples increased in all samples during storage. However, brix change in chitosan-coated apples were lower than that of control. The titrable acidity of juices of apples slowly decreased and pH increased. Significant differences were not observed between control and chitosan-coated apples. Hardness of apples decreased in all samples and the smallest change in hardness was observed in 30 cps 3% or 90 cps 2% chitosan-coated apples.

연구목적 : Catechol-O-Methyltransferase(COMT)는 카테콜아민 신경전달물질의 불활성화를 담당하는 효소로서, 정신분열병과 관련된 후보 유전자로서 알려져 왔다. 최근, 기능성 COMT유전자 다형성과 정신분열병의 관련성이 제기되었는데, 한국인 정신분열병에서도 이러한 관련성이 있는지를 살피기 위해 본 연구를 시행하였다. 방 법 : 정신분열병으로 진단된 환자군 103명과 성별 및 연령별로 1:1 짝짓기 대조군 사이에 유전자형과 대립유전자의 분포를 비교하였다. 또한, 환자군은 공격적 행동, 가족력, 아동기 발병 여부에 따라 두 군으로 나누어 비교하였다. DNA의 다형성 부의를 중합효소연쇄반응에 의해 증폭한 후 ,NlaⅢ제한효소법과 전기영동을 실시하여 유전자형을 판별하였다. 결 과 : 환자군 전체와 대조군 사이에 유전자형과 대립유전자 빈도의 차이가 없었다. 가족력이 있는 환자군을 대조군과 비교하였을 때는, 대립유전자 L을 포함하는 유전자형과 그렇지 않은 유전자형의 분포에 있어 유의한 차이를 보였다(p=0.02, OR=3.9, 95% Cl=1.1∼14.3). 결 론 : 한국인 정신분열병과 기능성 COMT 유전자 다형성 사이에 유의한 관련성이 없었다. 따라서, 기능성 COMT 유전자 다형성이 한국인 정신분열병의 발병에 영향을 주지 못한다. 그러나, 정신분열병 가족력과 기능성 COMT유전자 다형성의 관련성이 시시돠어, 향후 본 연구에서 나타난 방법론적인 문제점을 보완하고 추가 대상자를 확보한 연구가 필요하다. Objectives : Catechol-O-methyltransferase(COMT) is involved in the degradation of catecholamine meurotransmitters and has been investigated as a candidate gene in schizophrenia. Recently, possible relationship between functional COMT gene polymorphism and schizophrenia has been suggested. To address the possible role of functional COMT gene polymorphism in the predisposition to schizophrenia, we carried out an association study in Korean schizophrenic patients and controls. Methods : One hundred and three Korean inpatients diagnosed as schizophrenia and 103 age and sex matched controls were selected as study subjects. Patients were subgrouped into two groups on the basis of history of aggressive behavior, family history of schizophrenia and related disorders, and age at onset. We determined COMT genotypes using PCR of the relevant region followed by digestion with NlaⅢ and electrophoresis. Results : No significant differences of allele and genotype frequencies were noted between patients and controls. However, when patients were categorized by the presence of family history of schizophrenia and related disorders, patients with family history showed almost 4 fold higher frequency of having COMT L allele containing genotype compared to controls(p=0.02, OR=3.9, 9.5% CI=1.10-14.33). Conclusion : Although our results do not support an association between functional polymorphism of COMT gene and schizophrenia overall, the findings suggest an association between functional COMT gene polymorphism and familial schizophrenia. Further studies with large samples are needed to confirm this association.
