Objectives : Rhodiola rosea L. (Crassulaceae) is a plant living at the areas of high-altitude mountain, and Rhodiolae Radix(the root of R. rosea) has been used as a traditional medicine to decrease the symptoms of mental- or physical-stress in Asia and Europe. To examine the efficacy of Rhodiolae Radix on the oxidative stress, the anti-oxidative effects of the radix were examined, Methods : The effects of Rhodiolae Radix on several oxidative factors were examined in vitro, and also the effects were tested in the liver of rats which were treated with a high dose of alcohol during 2 weeks. Results : The extract of Rhodiolae Radix in vitro scavenged some oxidants, such as DPPH, Superoxide anion radical and LDL, and the extract also inhibited the oxidative capacity of linoleic acid, significantly. Meanwhile, in the in vivo test, the methanol-extract decreased some oxidation parameters, such as relative liver weight, TBARS and SOD activities, and also increased catalase activity in the liver of alcohol-loaded rats, But, the extract had no effects on GSH content and GSH-px activiy in the rats. Conclusion : The root of Rhodiola rosea has a strong anti-oxidative capacity, and also has some preventive properties aginst the alcoholic stress.

The aims of this study were to compare the status of dental caries between mental retarded persons(MR) and normal persons and investigated the association among dental caries and oral factors(plaque index, S. mutans, Lactobacillus, buffering capacity, salivary total IgA and anti-S. mutans IgA titers). DMFS index and plaque index were significantly greater in the MR person group than in the normal person group. The concentration of S. mutans-specific IgA was significantly greater in the normal person group than in the MR person group, but that of salivary total IgA was not show the significant difference. Salivary buffering capacity was significantly greater in the normal person group than in the MR person group, but the counts of salivary S. mutans and Lactobacillus were not significantly different. By age group(I: 9-11Y, II: 12-14Y, III: 15-18Y), DMFS index and plaque index were significantly greater in the MR person group than in the normal person group at III. The S. mutans counts and Lactobacillus counts were significantly greater in the normal person group than in the MR person group at I, but those were contrary at II, III. There was a high correlation among caries index and buffering capacity, level of S. mutans and Lactobacillus, plaque index at III.

The demand of blasting work in civil engineering work is increasing because of the increasing social infra-structural construction work. The blasting method creates large benefit in regard to the economic aspect and shortening construction period. This method, however, has problems to be solved in respect to the blasting vibration and noise. Blasting vibration and noise have been studied by many workers, regarding to the impact on the structure and human body. This investigation is concerned on the affect of blasting vibration and noise on the animals which is relatively new. In general, animals have inferior mental capacity than human in hearing but have higher sensitivity on the vibration and noise due to blasting. The object of this study is to investigate an appropriate measurement of lessening damage on the animals by vibration and noise due to blasting.

Carbon dioxide is the fourth most abundant gas in the earth's atmosphere, and it is widely used in the chemical industry. Solid carbon dioxide is commonly known as dry ice. At low concentration, carbon dioxide appears to have little toxicological effect. At higher concentrations, however, it can produce an increased respiratory rate, tachycardia, cardiac arrhythmia, loss of consciousness, convulsion, and even death. Management of carbon dioxide poisoning requires the immediate removal of an individual from the toxic environment and administration of oxygen. It is important to know the concentration of carbon dioxide to which a patient has been exposed. We report a case of acute poisoning from solid carbon dioxide in a patient presenting with drowsiness and diminished mental capacity when she arrived in the emergency department. She recovered completely after administration of oxygen with conservative treatment.

In Korea accelerated industry development and urbanization during the last three decades have led serious water pollution problems in many parts of the nation. Especially in the regions of west and south coast have low fresh water in the dry season of spring and summer. In the place isolated from land it is important to secure the fresh water for drinking and general service. This study is concerned on the thermal system design to develop low-pressure evaporation type fresh water gen-erator of capacity 1 ton/day using the heat source of non-operating boiler in the season of spring and summer. The results obtained from this study are as follows. the water quantitieds generated from experi-mental evaporator showed good coincidence with the calculated values. The maximum production quantity was 1.38ton/day at pressure 40mmHg abs. and temperature $80^{\circ}C$.

Background: Physical exercise during leisure time is known to increase physical capacity; however, the long-term effects on work ability and work strain are inconclusive. The aim of this study was to investigate the effects of a 6-month physical exercise program on work ability and work strain after 6 months and 30 months, among women with menopausal symptoms at baseline. Methods: A questionnaire including questions on work ability and work strain was mailed in the beginning, at 6 months and after 30 months after the intervention to occupationally active women participating in a randomized controlled study on physical exercise and quality of life. The intervention included aerobic exercise training 4 times per week, 50 minutes per session. Work ability was measured with the Work Ability Index (WAI) and with questions about physical and mental work strain. Results: Women aged 47-62 years (N=89) who were occupationally active at baseline were included in the analyses. The increase in WAI from baseline to the end of the exercise intervention (6 months) was statistically significantly greater among the intervention group than among the control group (regression coefficient 2.08; 95% confidence interval 0.71-3.46). The difference between the groups persisted for 30 months. No significant short- or long-term effects on physical and mental work strain were found. Conclusion: A 6-month physical exercise intervention among symptomatic menopausal women had positive short-term as well as long-term effects on work ability.

This study is conducted to analyse the process and the pattern of motivation for musical expression in clinical music therapy for the adults in the mental health center. The participant were 8 adults purposive sampling who had more than one year music therapy experience in the mental health center and their age ranged from 27 to 53. A major category derived and analysed from the grounded theory method by Strauss and Corbin. The qualitative analysis indicated that motivation for musical expression in music therapy, which was the central phenomenon in this study, was determined by the music therapist and songs used in the sessions. The central phenomenon was caused by the therapist's friendly attitude, high musical capacity, the familarity of the selected songs and the significancy of the lyrics of selected songs. The levels of reliability about the therapist's personality and musical ability as a professional music therapist and the positive arousal of the songs used in sessions affected as the contextual condition. Spontaneous musical expression in music therapy brought the escape from reality, release of stress and sharing by the intervening condition 'empathy' and this resulted in mood regulation, the instillation of hope and group cohesion. It has been found that there were three types of motivation in music therapy: intrinsic motivation, relationship dependent extrinsic motivation and evasive motivation.
