Objective: This study was performed to examine the relationship between community-based social support and psychosocial distress in workers. Methods: The study subjects were 596 workers recruited from 11 companies in Chungju city. A structured questionnaire was used to assess sociodemographics, health-related behaviors, job characteristics, job stress, work-based social support, community-based social support and level of psychosocial distress. Results: Hierarchical multiple regression analysis showed that workers with no chronic disease, exercise and sufficient sleep had a higher score of psychosocial distress than those with chronic disease, no exercise, and not enough sleep. Coworker's work-based social support and community-based social support were negatively associated with psychosocial distress. The R square value of total independent variables on psychosocial distress was 0.409, and that of community-based social support on psychosocial distress was 0.052. Conclusion: This study showed that community-based social support served as a protective factor against psychosocial distress in some workers. We recommend the establishment of a worksite stress reduction program in occupational level as well as community-based social support.

Excretory urography is a type of contrast study used to verify and localize upper urinary tract disease. It is an inexpensive and easy way to visualize of anatomic and functional status of the kidney and has been used as a primary imaging modality for the evaluation of urinary tract abnormalities. We describe urological signs of 7 dogs who examined with excretory urography and ultrasonography. Six cases were referred to veterinary medical teaching hospital. Chungnam national university (VMTH, CNU) to evaluate renal function after the treatment for renal failure and one case was referred showing hematuria. In case 1, 2 and 4, blood test and urinalysis was normal and the results of excretory urography presented that renal function were normal range. In case 3, the results of urinalysis, ultrasonography, and excretory urography except blood test presented abnormal kidney and hydronephrosis was diagnosed. In case 5 and 6, blood test, urinalysis, ultrasonography and excretory urography indicated renal failure. In case 7, blood test, urinalysis and ultrasonography presented partially abnormal signs, however, the results of excretory urography was normal range.

The purpose of this study was to investigate the effect of treadmill exercise programs on cardiopulmonary functions and serum lipids in adult obesity men. The subjects consisted of 33 obese adults between 30 and 70 years old and all of them had no other complications. Subjects participated in treadmill exercise programs for 12 weeks according to the exercise prescriptions. They started to exercise for 20 minutes per day, six times a week at 50% of maximum O_2 consumption (V˙O_2max), and later exercised for 50 minutes at 80% of V˙O_2max, which was the maximum exercise intensity of the program (Exercise intensity has been increased gradually). The changes of body composition, serum lipids, and cardiopulmonary functions in the subjects before and after the treadmill exercise program have been measured. The results are as follows. 1. Body weight, percent body fat, and fat body weight were reduced(p<0.05, p<0.01), and body fluid were increased after exercise programs(p<0.01). The group below 50 years old and above 25% of body fat showed more decrease in body weight and percent body fat, and more increase than that above 50 years old below 25% of body fat. 2. Resting heart rate, systolic and diastolic blood pressure were significantly reduced after exercise programs(p<0.05, p<0.01), but these parameters decreased approximately same for the groups of ages and percent body fat. 3. Vital capacity, forced expiratory volume for 1 second percent and maximal voluntary ventilation were increased after exercise programs. The group below 50 years old and above 25% of body fat showed more increase than that above 50 years old and below 25% of body fat. 4. Total cholesterol, LDL cholesterol, total cholesterol/HDL cholesterol rate and triglycerides were reduced (p<.05, p<0.01), and HDL cholesterol levles were increased after exercise programs. The group below 50 years old and above 25% of body fat showed more decrease in total cholesterol, LDL cholesterol, total cholesterol/HDL cholesterol rate and triglycerides, and more increase than that above 50 years old and below 25% of body fat. 5. Heart rate increase during exercise were reduced after exercise programs. The group below 50 years old and above 25% of body fat showed more decrease than that above 50 years old and below 25% of body fat. 6. Blood pressure increase during exercise were reduced after exercise programs. The group above 25% of body fat showed more decrease than that below 25% of body fat. 7. Oxygen uptake of during exercise were increased after exercise programs. 8. Maximal oxygen uptake were significantly increased after exercise programs (p<0.01). 9. The regression equations between heart rate, systolic blood pressure, and oxygen uptake were obtained. These correlation coefficients of the post-programs showed higher that those of pre-programs. In this study, the treadmill exercise programs suitable for the obese was developed and applying this programs weight, percent of body fat, body fat weight, and serum lipids levels ere reduced. Thus cardiopulmonary functions was improved. The group below 50 years old and above 25% of body fat showed more decrease than that above 50 years old and below 25% of body fat. It is to be noted that both systolic blood pressure and oxygen uptake can be estimated by heart rate only using the regression equations.

The fermentation characteristics such as pH, acidity, lactic acid bacterial counts and panel taste of kimchi, and antimutagenic activity of kimchi were studied when the kimchi prepared with different ratio of seed (S) pericarp (P) in red pepper powder and fermented at 15℃. The pHs of P:S = 9:1 kimchi and P:S = 7:3 kimchi decreased gradually during the kimchi fermentation, however, pHs of P:S = 5:5 kimchi and P:S = 3:7 kimchi decreased very fast during the fermentation. The counts of Leuconostoc sp were high in P:S = 9:1 kimchi and P:S = 7:3 kimchi but the levels were low in P:S = 5:5 kimchi and P:S = 3:7 kimchi. Whereas Lactobacillus sp counts were low in P:S = 9:1 kimchi and P:S = 7:3 kimchi, but the counts were high in P:S = 5:5 kimchi and P:S = 3:7 kimchi during the fermentation. P:S = 3:7 kimchi showed the highest prevalence in the panel taste of the kimchis and the P:S = 3:7 kimchi resulted in the lowest prevalence. The antimutagenic activities of the kimchi juices were studied by Ames test using Salmonella typhimurium TA100 and SOS chromotest using E. coil PQ37. As the ratio of the seed increased, the antimutagenicities increased. Among the kimchi samples, P:S = 5:5 kimchi significantly reduced (p<0.05) the mutagenicities induced by aflatoxin B_1(AFB_1) in Ames test and SOS response against N-methy1-N'-nitro-N-nitrosoguanidine (MNNG) in SOS chromotest. From the results of the experiments, the P:S = 7:3 kimchi seems to be the best seed ratio of red pepper powder for the preparation of kimchi in terms of fermentation characteristics and antimutagenicity of the kimchi.

The effect of electrochemical process to treat the industrial Wastewater for removal of COD_Mn was described in this study. The tests on COD_Mn, pH and conductivity were performed. It was shown from the tests that, in regard to efficiency of COD_Mn removal, 1.5㎝ between the electrodes for electical resistance was optimally appeared. The COD_Mn concentration and conductivity of the waste water were initially decreased when the voltage charge was increased. Removal of COD_Mn was predominantly occurred with addition of NaCl and increase of retension time. The optimal amount of NaCl solution was 2,000㎎/L. The effective removal of COD_Mn was appeared when current density was increased and pH was decreased.

The inhibitory effect of the fresh juice of kale on the genotoxicity induced by aflatoxin B_1 (AFB_1) in Salmonella and Drosophila was investigated. The kale juice had strong inhibitory activity for His^- to His^+ reverse-mutations induced by AFB_1 acting on S. typhimurium TA100. A similar inhibitory effect was detected in somatic cell mutation assaying system of D. melanogaster. Using the wing hairs spot test, we found that the formation of mutant hairs in adult flies as a result of feeding with AFB_1 in their larval stages was efficiently inhibited by coadministration of the fresh juice of kale, which revealed that it can inhibit gene mutation, deletion and mitotic chromosomal recombination. These results seem to suggest that kale juice may exert its inhibitory effect to mutagenic and/or carcinogenic properties of DNA damaging agents.

To develop kimchi for cancer patient, we studied on enhancing antimutagenic effect of kimchi by manipulating the recipe from the result of prevalence test on kimchi by cancer patients. According to the result of prevalence test, the patients wanted to reduce the level of red pepper powder and increase some sub-ingredients such as garlic and mustard compared to the standardized kimchi. The recipe-manipulated kimchi was fermented at 15℃ for 1 day and then ripened at 5℃ for several days up to pH 4.2~4.3. The antimutagenic effect of the methanol extracts of the kimchi was evaluated by using Ames mutagenicity test with Salmonella typhimurium TA100. Among the kimchi samples, CP_2-M kimchi (2.5% red pepper powder +7.5% mustard leaf added kimchi) exhibited higher inhibitory effect on the mutagenicity induced by aflatoxin B_1 in the Ames test. In vivo supravital staining micronucleus assay, anticlastogenic effect of the CP_2-M kimchi group was higher than that of the control group. The induction of chromosome aberration by mitomycin C was significantly suppressed by CP_2-M kimchi suggesting in post-treatment.

A Bicon Frise (7-month-old, intact female, B.W.: 3.5kg) was referred to the Veterinary Medical Teaching Hospital of Chungnam National University with the history of the murmur which was picked up during routine vaccination. The grade 3 of continuous murmur was identified on the auscultation. In the thoracic radiography, descending aorta and main pulmonary artery were enlarged and vertebral cardiac scale (VHS) was 10. In the echocardiography, turbulent and continuous positive flow was identified in the pulmonary artery at the right parasternal short axis view. We found the patent ductus arteriosus (PDA) connected the main pulmonary artery with the aorta by CT image. So, the diagnosis of PDA was made. The continuous murmur was not identified on the auscultation after surgical correction was achieved by ligation of PDA.

This experiment was done on 30 fencers that had joined the national competition and had a research on theft heart rates during the fencing bout and got the following results. 1. In average, a male fencer have a height of 178.40㎝, weight of 72.50㎏, the height when sitting of 93.70㎝, the chest perimeter of 94.70㎝, arm length of 56.50㎝, and thigh parameter of 60.20㎝. In average, for a female fencer, had a height of 167.98㎝, weight of 59.00㎏, the height when sitting of 87.00㎝, chest perimeter of 84.50㎝, the thigh perimeter of 58.30㎝, and the arm length of 50.90㎝. From the result of testing a fencer's endurance by general footwork, it was proofed that the evaluation of respiratory function was needed more. 3. When comparing the heart rates of male fencers in the fencing bout of fleuret and epee, we found out that the fleuret fencer had a higher heart rate, in average of 17.06beat/min, than the epee fencer. However, there was not much difference with the heart rates during the bouts of sabre and fleuret Clearly, the bout during epee showed lowest heart rate among these three subjects. 4. The heart rates during female's fencing bout, there was not much difference with the heart rates in the male's fencing bout, and the heart rate during a bout of epee was about 18.59beat/min lower than fleuret.
