This study was designed to identify the general health conditions and high risk factors of the male & female environmental workers. Thereby. the results of this study were to provide useful data as a contribution to knowledge for health protection and promotion. The data used for this study were environmental workers' physical examination cards; the male environmental workers were 52 persons. and the female environmental workers 52 persons. The data were analyzed by descriptive statistics, t-test, Pearson correlation, and distinction analysis, using the SPSS program. The results of this study can be summarized as follows; 1. Thers was a significant statistical difference between the two groups as to height. eyesight. serum GPT, hematocrit. The variables having little difference between two groups were weight. systolic blood pressure. total cholesterol. creatinine. 2. The rate of revealed in significant health examination was extra-health discrimination rate $28.8\%$, significant result of illness rate $12.5\%$. injury-inflicting rate $7\%$. second-time urine test $5.7\%$. antigen positive 3.8%. hearing impairment $2.8\%$, urine protein positive $1.9\%$. and urine sugar positive $1.9%$. 3. The workers diagnosed as extra-health discrimination were 30 persons or $28.8\%$. There was a difference between two groups on the prevalence. In the male environmental workers. ten times live problems and six times pulmonary tuberculosis and three times circulatory problems were revealed the higher than thoes of the female environmental workers. 4. In the male environmental workers, the relationship between age and systolic blood pressure revealed a significant correlation (r=0.22. p<0.05). In the female environmental workers. there was a negative correlation between age and weight (r= 0.25, p<0.05). the relationship between age and total cholesterol correlated positively (r=0.30, p<'0.05). 5. In the male environmental workers, there was a negative correlation between working career and creatinine(r=-0. 22, p<0.05) In the female environmental workers, there was a positive correlation between working career and total cholesterol (r= 0.58, p<0.01). 6. There were significant differences on working career and creatinine accdording to the male and female environmental workers who had any problems through x-ray inspection. 7. There were significant differences on height. eyesight. serum GPT according to the male and female environmental workers who were diagnosed as extra-health discrimination. 8. The female environmental workers who were diagnosed as 'care' were positively correlated with weight (r= 0.26. p<0.05)' and systolic blood pressure (r= 0.30. p<0. 05). on the other hand. the left and right eyesight correlated nagatively(r=-0.15. r=-0.33. p<0.01). 9. The most influential variables on the male and female environmental workers' health condition were working career, height. and weight. And these three variables could help determine the two groups at the level of 81. 8 percentage.

식물세포의 느린 생장과 낮은 생산량의 이유로 지금까지 는 주로 미생물이나 동물세포에서 유전자 재조합 단백질을 생산하여 왔다. 그러나 저렴한 배지 가격, 동물 유래 바이러스 감염 위험성으로부터의 안정성, glycosylation 등의 post-translational modification이 가능하다는 장점들로 인하여 최근 들어 식물세포배양은 생물학적 활성을 가진 고부가가치의 단백질을 생산하는데 많이 이용되고 있다. 본 연구에서는 생장배지에 첨가했던 sucrose의 소비와 induction 배지로의 교환에서 오는 배지내의 삼투압을 조절하여 hCTLA4-Ig의 생산성을 높이고자 하였다. 다양한 삼투압 조절제 첨가 실험을 통해 sorbitol을 선별하고, 40 mM의 sorbitol 첨가에서 상대적으로 높은 생존도와 induction 후 7일째 대조구보다 1.7배 높은 생산성을 확인하였다. 또한, 저농도의 glucose 첨가를 통한 생산성 증대에 있어서는 8 mM glucose에서 induction 이후에도 높은 세포농도를 유지하면서 최대 37.3 mg/L까지 hCTLA4-Ig 생산량을 증가시켰다. 5-L bioreactor에서 회분식 배양과 induction시의 hCTLA4-Ig 생산량을 비교한 결과 induction시 배양 18일째 최고 45.3 mg/L까지 높일 수 있었으며, 회분식 배양에 비해 2.1배 증가됨을 확인하였다.

Bambusae caulis in Liquamen is one of the important herbal medicine produced by heating bamboo indirectly and is used for treatment of stroke, hypertension, and diabetes etc. Recently the mechanism of clinical effects on Bambusae caulis in Liquamen has been studied. This experiment was conducted to confirm the clinical effects of Bambusae caulis in Liquamen on type 1 diabetes and its related mechanism. We divided C57BL/6 mice into 3 groups and induced them to be type 1 diabetes by injection of streptozocin into peritoneum. The dosage of each group was 150 mg/kg once only, 140 mg/kg once only and 40 mg/kg for 5 days respectively. The two groups injected streptozocin for once took orally Bambusae caulis in Liquamen after the induction of diabetes, and the other one group was given Bambusae caulis in Liquamen during the diabetes inducing period. As the result, the two diabetes-induced groups showed blood glucose decreasing effect by Bambusae caulis in Liquamen on an average, but they didn't show the signiftcant differences statistically. But Bambusae caulis in Liquamen showed the anti-diabetic effect suppressing blood sugar rising trend during the diabetes inducing peried (P<0.05). The anti-oxidative effect of Bambusae caulis in Liquamen was measured with the hypoxanthine/xanthine oxidase (HX/XOD) system. The quantity of ROS was measured using DCFDA reagent indirectly. As the result, $10\%$ solution of Bambusae caulis in Liquamen showed anti-oxidative effect by scavenging $93.4\%$ superoxide as compared with control group. It is suspected that the anti-oxidative effect of Bambusae caulis in Liquamen suppressed the increase of blood glucose in the diabetes-inducing group. These results could be useful data to understand the effect of Bambusae caulis in Liquamen on type 1 diabetes and type 1 diabetes developing because ROS were closely connected with the induction and complications of diabetes.

To develop the low-temperature and long-term fermented kimchi, kimchi was prepared according to the recipe of a specific ratio of major and minor ingredients and adjusted its salinity to 3.7%. Prepared kimchi fermented at $15{\pm}1^{\circ}C$ for 24 hours and transferred and fermented in a refrigerator only used to make low-temperature and long-term fermented kimchi at $-1{\pm}1^{\circ}C$ for 30 weeks. During 30 weeks of fermentation the changes in physicochemical and microbiological properties of low-temperature and long-term fermented kimchi were studied. The initial pH of 6.47 decrease gradually and dropped to pH 4.0 after 14 weeks of fermentation, and then it maintained at same level. Acidity increased to 0.49% on 2 weeks of fermentation and kept at 0.47 $\sim$0.50% during 2 to 30 weeks fermentation. Salinity was slightly increased at early stage and started to decrease on 4 weeks of fermentation, and then it did not change. The change of reducing sugar content was closely related to the trend of pH change with a very high correlation coefficient(r =0.912). Lactic acid, citric acid, malic acid, succinic acid and acetic acid were major organic acids contained in low-temperature and long-term fermented kimchi. Vitamin C content decreased at initial stage of fermentation and then slightly increased up to the maximum of 22.3 mg% on 8weeks of fermentation. In color measurement, L value continued to increase during the fermentation and reached at the highest of 55.45 on 22 weeks of fermentation, and a and b values of 3.62 and 4.54 also increased to 31.26 and 37.32 on 30 weeks of fermentation, respectively. Total microbial count increased slowly from beginning and was the highest on 4 weeks of fermentation, and then began to decrease slowly. Count of Lactobacillus spp. was highest after 6weeks, but count of Lactobacillus spp. was highest on 2 weeks of fermentation, and then both showed a slow decrease. Yeast count wasn't increased until 4 weeks of fermentation and then increased rapidly to get the highest on 10 weeks of fermentation.

The purpose of this study is to determine the clinical nurses' knowledge of DM and diabetes patient education aptitude so as to provide a basis for clinical nurse training with respect to diabetes patient education program. The data has been collected through the questionnaires of 42 items from the Knowledge on DM and each 16 item from the Importance on the elements of diabetes patient and the Recognition for clinical nurses, respectfully. 166 nurses from a general hospital who had participated in clinical nurse training in Sep. 28 and Oct. 4, 2001 were subject to respond the questionnaires. Analysis has been done by using statistical method such as percentage, average, standard deviation, t-test, ANOVA, Duncan test and Pearson correlation coefficients. The findings are as follows: 1. Clinical nurses' knowledge levels of diabetes 1) The average level of nurses' knowledge about diabetes is 29.37 (right answer- finding rate: 70%), which is intermediate. 2) Amongst the nurses classified by their knowledge levels about diabetes, the group with less than one year career and that with more than 5 year careers are found to have higher knowledge levels. The item with the highest right answer-finding rate was 'Please find the wrong out of the following examples about foot care'. Meanwhile, the item with highest incorrect answer-finding rate was 'what does blood sugar control aims for amongst gestational diabetes?'. 2. Clinical nurses' importance and perception levels of educational training about diabetes 1) There were no differences amongst nurses' importance level about diabetes. 2) Nurses usually had high scores(4.30) in terms of the items related to the importances about educational training. 3) There were quite high recognitions of general characteristics and symptoms about diabetes, amongst the nurse cohorts working more than one year and less than 5 years, and over 5 years, the group belonging to the internal department, that having the previous experiences of dealing with diabetes, and that having their diabetic relatives and other close people. Meanwhile, strangely, the group who identified themselves as 'not good at treating diabetes' had a high recognition level of educational training about diabetes. 3. Relationship between knowledge levels and importance & perception levels of diabetes 1) The higher knowledge about diabetes nurses had, the more importance they recognized. 2) It is found that there was no relationship between knowledge and perception of diabetes. 3) The more importance about diabetes nurses had, the higher perception they obtained. In conclusion, there is an urgent need for systematic educational programs about diabetes including technical aspects, in order to upgrade and improve nurses knowledge levels. In addition, re-educational training should be provided at regular intervals. Further, we believe the nurses with high knowledge about diabetes and interests in the provision of educations for patients can be far more confident, and in return, patients can have better self-management about diabetes obtained through educations. Based on the above-mentioned findings, we would like to make the suggestion: re-evaluation about nurses' knowledge and cognition levels should be carried out after job training programs about diabetes.

The sensual quality of Bokbunja Teriyaki sauce and a roasted eel spread with Bokbunja Teriyaki sauce was analyzed to detemine the merchandising potential of this sauce. The moisture content of the Teriyaki sauce decreased as the amount of added Bokbunja increased, and the 3% group showed the highest decrease, which was 73.1%. As the amount of added Bokbunja increased the pH was showen to decreased, and the sweetness of the Teriyaki sauce increased. The sauce containing 12% Bokbunja had the highest increase of $36.9^{\circ}Brix$. The amount reducing sugar was significantly different between each sample. In terms of the L (lightness) value, highter amounts of added Bokbunja resulted in an increase in the L (lightness) of the sauce and significant differences were obsered between sample groups. In regards to the texture, no significant changes were shown for hardness even though the amount of Bokbunja added was different. There was a significant difference between samples for gumminess, a highter concentration of Bokbunja resulted in a higher gumminess of the sauce. As for adhesiveness, there was a significant difference between samples; as more Bokbunja was added, the sauce became betwkier. In regards to the preference of roasted eel containing this sauce, the 6% Bokbunja sauce was the most preferred with a score 7.98 points, and as for flavor, there was significant difference between sauces containing 3, 6 and 9% Bokbunja. In addition there wasn't any significant difference between each sample for sweetness. For softness, the 6% Bokbunja sauce was the most preferred with a score of 9.36 points. The overall-acceptability was in this order: 6>9>3>0>12%, Thus, from the physico-chemical and sensual perspective, the 6% Bokbunja sauce is highly recommended for potential commercial use. In conclusion, we examined the effect of combining Bokbunja, which has medicinal applications and excellent functionality, with Teriyaki sauce and the results of this study indicate that Bokbunja combined Teriyaki sauce produce a high quality food that holds promise for commercialization.

키토산 올리고당을 효율적으로 생산하기 위하여 고정화 효소 를 이용한 키토산의 효소적 가수분해를 시도하였다. Chitosanase는 Chitopearl계 고정화 담체에 대해서 높은 흡착율로 결합되었다. 키틴에 고정화된 효소는 비록 흡착율은 낮았지 만 그 활성은 가장 높게 나타났다. 키틴 고정화 효소는 유리 효소에 비해 약 90% 이상의 활성을 유지하였다. 고정화 효소의 최적 온도는 60°C로서 유리 효소보다 $15^{\circ}C$ 더 높았으며, 열에 대한 안정성도 유리 효소보다 넓은 온도범위에서 우수하였다 그러나 고정화 효소는 pH에 대해서는 어떠한 뚜렷한 효과도 보이지 않았다. 고정화 효소의 저장 안정성은 유리 효소보다 더 높은 저장온도인 60t에서도 더 안정한 것으로 나타났다. 키틴 고정화 효소에 의한 키토산의 가수분해반응은 반응 3시간까지 급격한 증가를 보이다 그 이후의 반응시간 경과에서도 더 이상 증가를 보이지 않았다. 고정화 효소에 의해 생성된 올리고당의 조성은 효소의 반응시간에 따라 크게 의존하였으며, 2시간의 반 응에서 비교적 고차 올라고당인 COS-4-6의 함량은 약 90% 이상이었다 두 효소에 대한 반용속도상수에서, 고정화 효소는 유리 효소에 비해 낮은 기질친화성과 낮은 반웅속도를 보였지 만, 높은 기질농도에서도 전혀 기질저해반응은 일어나지 않았다. 따라서 키틴 고정화 효소는 유리 효소에 비해 활성의 감소없이 효율적으로 키토산을 가수분해할 수 있었으며, 고차 올리고당의 생성 량도 매우 높았다.
