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.

To establish the way of processing of Gae-Woo jeot which used abalone intestine that has not been systematically used compare to its characteristic taste and fame as main ingredient and to develop as a local tourist good, the change of constituents the quality of salted fish products suring Gae-Woo jeot fermentation were examined. The results are as follows. 1. In the organoleptic test, Gae-Woo jeot which fermented through 65 days were dominant and the group of 105 salkt concentration were better than that of 20%. It was the best of 10% salted products to add small abalone. Both law salted(10%) and high salted (20%) Gae-Woo jeot were similar in general constityents, nutrients and texture. 2. Compositions of highly unsaturated acid were farely high to 45.6% and 46.1% in small abalone added froup and top sheel added group respectively. during 3 months fermentation low decreasing rate of 3~4% was shown. EPA(eicosapentaenoic acid) was approximately 7~8% and DHA(docosahexaenoic acid) was extremely low to be less than 0.3%. 3. In the changes General composition and pH, pH was within range of 4~5.5, 9~12% in protein, 3~5% in total sugar, 0.5~1% in lipid and approximately 1% in ash. 4. Gae-Woo jeot can be made with 10% low salting method, and 10% group gets all the better for taste, small abalone adding is recommended. 5. When low salt fermented fish of 10% is processed, it is highly recommended to put sorbitol, ethyl alcohol, lactic acid or other humectant for better taste and longer storage and good quality food additives must be developed for tourist and presently applied mil ordering transportation must be sought.

This study was to estimate the total amount of domestic and imported organic solvents production. Potential hazard was evaluated through the amount and physical properties. According to his primary risk assessment, toluene, MEK and perchloroethylene were chosen to analyze the solvents in air and their metabolites in blood and urine for using in biological monitoring in the future. The results were as follws. 1. The amount of organic solvent consumption was about 3 million tons in 1989. Of all organic solvents, 70% were aromatic hydrocabons, 12% alcohols, 5% ketones, 3% aliphatic hydrocabons respectively. Xylene in aromatic hydrocabons, cyclohexane in aliphatic hydrocarbons, methanol in alcohols, acetone in ketones, and trichloroethylene in chlorinated hydrocarbons have been more frequently consumed. 2. Benzene was the most hazardous solvent followed by carbon tetrachloride, methanol, toluene, xylene and its derivatives, dichloromethane, chloroform, ethylene tetrachloride, cyclohexane and MEK. respectively. Of the chlorinated hydrocabons, all except methylchloroform were relatively, hazardous in this assessment. 3. The MEK in urine was a good indicator to pridice MEK exposure. The MEK in blood had high correlation with the MEK in urine. Both the blood and urine MEK were more specific when subjects were exposed to higher level. The urine and blood MEK corresponded to exposure of 200ppm MEK were 1.37mg/l and 2.83mg/l 4. The perchloroethylene in blood and trichloroactic acid in urine were good indicators to predict perchloroethylene exposure. Both the pechloroethylene in blood and trichloroacetic acid in urine were more specific when subjects were exposed to higher level. The perchloroethylene in blood and trichloroacetic acid in urine corresponded to exposure of 50ppm perchloroethylene were 1.43 mg/l and 2.56mg/l 5. The hippuric acid in urine and toluene in blood were good indicators to predict toluene exposure. The corrected hippuric acid with creatinine was more useful to exposure to toluene. The toluene in blood was more useful than the hippuric acid in urine, even if subjects were exposed to lower level. The hippuric acid in urine and toluene in blood corresponed to exposure of 100ppm toluene were 1.71g/g creatinine and 2.06mg/1.

To investigate the effects on body components of sea bass by the supplemented carotenoids, fish were fed the diet each containing β-carotene, lutein ester, astaxanthin, astaxanthin monoester and astaxanthin diester for 8 weeks. Amino acids, nucleotides and their related compounds and fatty acids in muscle were analyzed. The contents of total amino acid were higher in astaxanthin monoester group than in other groups. The contens of total free acid were higher in astaxanthin monoester group than in other groups. In astaxanthin monoester group, the contents of taurine, threonine, proline, alanine, leucine, lysine, histidine and arginine were markedly higher than that of other groups, while the content of glutamic acid was lower. IMPlevel in astaxanthin monoester group was higher than that of other groups by the greatly increased during feeding experimental diet. In astaxanthin monoester group, saturated fatty acids were decreased during feeding experimental diet, while polyunsaturated fatty acids were increased. In summary, the level of amino acids, nucleotides and their related compounds and polyunsaturated fatty acids were higher in astaxanthin monoester group than in other groups. This suggested that the deposition of carotenoid was affected on these body components.

This experiment studied on the change of carotenoid pigments and its stability in modified oleoresin from tangerine peel during thermal treatment at high temperature. Violaxanthin among carotenoid pigments of raw tangerine peel, was most abundant colorant (18.84mg%) followed by cryptoxanthin-(17.88mg%), luteoxanthin(7.93mg%), antherxanthin(5.16%), phytoene(3.78%) and zeaxanthin(3.48mg%). Oleoresin was acquiesce in the same order of raw tangerine peel. The transmiting ranges of twelve color components from raw tangerine peel to oleoresin were 72.8~89.5%. Transmittal of carotenoid pigments was over 85% in neoxanthin, lycopene, violaxanthin and cryptoxanthin, and over 70% in α- carotene, lutein and luteoxanthin. The sums of twelve color component contents in oleoresin tangerine peel were remained 67.1% and 45.2%, respectively, after thermal treatment for 60 minutes at 10℃ and 200℃ under air circumstance, but those under nitrogen circumstance were 89.8% and 81.4% respectively.

The purpose of the study was to investigate the effects of the low level irradiation on the mitotic index of the basal cells in the buccal pouch of hamsters(golden hamster: APG strain). After colchicine was administrated to the hamsters through the intraperitoneal. the low level radiation(5460mR) was exposed on the buccal pouch of hamsters. The mitotic index of the basal cells was estimated 2 hours after irradiation. The results were as follows: 1. The mean mitotic index of the control group was 4.32. 2. The mean mitotic index of the irradiated group was 2.46. 3. T-test of data in the irradiated group showed significant difference from the mitotic index in the control group. These results suggested the lowered mitotic index of the irradiated group resulted from the low level irradiation.
