Proceedings of International Symposium on East-West Medicine, Seoul. 244-254, 1999.-Obesity can be defined as a metabolic disease due to an increased state of fat tissues caused by an imbalance of calorie intake and use. Recently, in Korea by improvement and westernization of food intake, along with decrease in exercise activities, the prevalence of obesity has increased greatly. Our objectives were to study stability and effects of decrease in body fat by administering red ginseng compound preparation (known to have body fat decreasing effects in laboratory animals) to obesity patients on low calorie diets. Changes in weight and body fat were measured while carrying out calorie-restricted diets on patients for 4 weeks, then administering red ginseng compound preparation for another 4 weeks. The patients were 20 people whose BMI were 25kg/㎡ or over and whose percent body fat was also 30% or over when tested by bioelectrical conductivity. 1. Changes in weight were from 70.04kg(base line) to 67.43kg(after taking red ginseng compound preparation). 2. In similar sense, BMI decreased from 27.12kg/㎡(base line) to 26.56kg/㎡(after dieting), and further to 26.01kg/㎡ (after taking red ginseng compound preparation). The BMI seemed to decrease significantly compared to the baseline after the use of red ginseng compound. 3. Waist hip ratio was changed from 0.8858(base line) to 0.8728, but it was statistically insignificant. 4. The percent body fat was 35,16%(base line), 33.87%(after dieting), and 31.68%(after taking red ginseng compound preparation). 5. Complete blood cell count and blood chemisrty remained unaffected by the administration. 6. In concern to endocrinologic studies, T3 decreased from 118.7 to 98.2ng/dL, and T4 increased from 8.8 to 9.2㎕/ dL. Epinephrine showed a tendency to decreased from 0.27 to 0.25 ng/mL, and norepinephrine increased from 0.39 to 0.44ng/mL. 7. Leptin was not changed. 8. Some patients complained adverse effects; constipation(5 patients, may be due to diet therapy), fatigue (2 patients), pruritus(2 patients), flushing(s patients), dizziness(3 patients) and epigastric discomfort(2 patients). However their symptoms were mild, so medication did not stopped. In conclusion, loss of weight without significant side effects was observed during low calorie diet and red ginseng compound preparation administration. This is thought to be in relation to sympathetic nerve system rather than adrenal gland. Also, further long0term studies should be required, since the observed results were based on short-term changes in weight.

In this study, we evaluated genotoxicity of heavy metals among particulates with Tradescantia-micronucleus (Trad - MCN) assay in the various working environment. In a synthetic fiber factory and a rubber factory, chromium concentration was higher than any other heavy metals. On the other hand, nickel concentration was the highest in a semi-conductor factory. The difference in genotoxicity among the working environment was statistically significant as Trad-MCN frequencies were 4.67±0.35 MCN/100 tetrads (p<0.01) for the synthetic fiber factory, 5.73±0.81 MCN/100 tetrads (p<0.0I) for the rubber factory, and 15.60±2.58 (p< 0.01) (p< 0.001) for the semi-conductor factory. As a result, heavy metals among particulates in the working environment can be considered to have hazardous potential to human health, although they cannot directly induce DNA damage to the workers in the working environments.

Waste water-soluble cutting oil was treated with W1 type #1 and W1 type #2. The properties of the original water-soluble cutting oil were pH=10.4, viscosity=l.4cP, CODcr=44,750 ppm, and TOC=10,569 ppm. However, the properties of the oil used for more than 3 months were changed to pH=7.82, viscosity=2.1cP, CODcr=151,000 ppm, and TOC=74,556 ppm. It might be attributed to the fact that molecular chains were cut due to thermal oxidation and impurities such as metal chips were incorporated in to the oil during the operation processes. To prevent the putrefaction of oil, the sterilization effect of ozone and UV on the microorganism in the oil was investigated. Ozone treatment showed that 99.99% of the microorganism was annihilated with 30 minutes contact time and 60 minutes were necessary for the same effect when UV was used. Ozone treatment could cut molecular chains of the oil due to strong sterilization power, which was evidenced by the increase of TOC from 25,132 ppm at instantaneous contact to 28,888 ppm at 30 minutes contact time. However, UV treatment didn't show severe changes in TOC values and thus, seemed to cause of severe cut of molecular chains. When the activated carbon was used to treat the waste water-soluble cutting oil, TOC decreased to 25,417 ppm with 0.1g carbon and to 15,946 ppm with 5.0g carbon. This results indicated that the waste oil of small molecular chains could be eliminated by adsorption. From the results, it could be concluded that these treatment techniques could be proposed to remove the waste oil of small molecular chains resulting in the degradation of the oil properties. In addition, these experimental results could be used for the correlation with future works such as investigation of the molecular distribution according to the sizes, lengths, and molecular weight of the chains.

Korea has gone into the aging society since 2002, and is now expected to enter aged society by 2018 and super-aged society by 2026. As such the aging of Korean population is now progressing at a rapid rate from the global perspective. A life span of Korean has been greatly prolonged and thus the proportion of the aged in the whole population has been increased steadily. These, in turn, are worsening all the poverty problems related with the aged and national pension scheme of which may put more burdens on national finance. Moreover, medical, healthcare, social security and employment issues are also accompanied with those previously stated problems. If the population ratio of the aged goes over 25% of total population then the economical power of the nation and its competitiveness in a global world can be weakened. It can also cause a decrease in working age population and which in turn may have negative impacts on the nation's overall industrial sectors. Hence, in order to avoid or prevent these undesirable situations, legal and/or political countermeasures on a national level are required. Moreover, about 40% of the nation's total population is expected to be converted into the aged population in just a few decades. Therefore a huge social crisis is anticipated, and that kind of social phenomenon can bring a serious situation on national level. In this regard, the salary peak system was introduced to Korea as a substitute for the voluntary retirement after financial crisis in 1998 but it is considered that the objective of the salary peak system in Korea was mainly for reducing labor costs while it is regarded as an alternative for the aging society in other countries. Accordingly this articles is studied to establish rational policies of salary peak system for aging society in Korea and also concepts of salary peak system, practical cases of firms and issues and improvement devices. Therefore, its current system seems to have several problems. First, Korean salary peak system fails to provide proper jobs for aged workers due to its fundamental problem of not focusing on utilizing aged work force but reducing cost, initially. Second, there are insufficient support from government necessary for carrying out salary peak system. Third, Korea has experienced a difficulty in reaching a consensus on salary peak system. Therefore, for securing the success of salary peak system, it is essential to solve these problems before its being introduced.

목적: 중소규모 사업장 근로자들의 직무 스트레스로 인한 결근, 조퇴의 현황과 한국형 직무 스트레스 하부 요인과의 관련성을 알아보고자 하였다. 방법: 중소규모 사업장 83곳 근로자들에 대해 한국형 직무스트레스요인 평가도구-단축형(KOSS-SF)과 사회 일반적 특성, 직업적 특정 및 직무스트레스로 인한 결근이나 조퇴 경험여부 등을 묻는 구조화된 자가 기입식 설문을 실시하였고, 응답한 4,350명에 대해 최종 분석을 시행하였다. 직무스트레스로 인한 결근, 조퇴와 한국형 직무스트레스 하부 요인들과의 관련성을 확인하기 위하여 로지스틱 회귀분석을 시행 하였다. 결과: 직무 스트레스로 인한 결근, 조퇴를 한 근로자는 남자에서 7%(196명), 여자에서 8%(113명) 로 조사되었고 한국형 직무 스트레스 하부요인과의 관련성에서는 남, 여 모두 직무요구, 관계갈등, 조직체계, 보상부적절, 직장문화 영역의 스트레스가 높은 군에서 통계적으로 의미있게 직무스트레스로 인한 결근, 조퇴율이 증가하였다. 결론: 중소규모 사업장 근로자들의 직무 스트레스로 인한 결근, 조퇴와 한국형 직무 스트레스 하부요인과의 관련성은 남자에서는 조직체계 영역이 가장 높았고, 여자는 직장문화 영역에서 가장 높은 관련성을 보였다. Objective: The aim of this study was to examine the actual conditions of absence and early leave due to job stress of 4,350 workers in 83 small and medium scale industries, and its relationship to job stress factors using Korean Occupational Stress Scale-Short Form (KOSS-SF). Methods: A structured self-reported questionnaire was used to assess each respondent's Sociodemographics, job stress, experience of absence and early leave due to job stress. Seven KOSS-SF domains of job stress were used. We estimated the relation of absence and early leave due to job stress and job stress factors using logistic regression analyses. Results: Absence or early leave due to job stress occurred in 7% of male workers and 8% of female workers. Multiple regression analysis revealed a significantly positive association job stress-related absence/early leave and job demand, interpersonal conflict, organizational system, lack of rewards and occupational climate. Conclusions: Absence and early leave due to job stress is significantly attributed to organizational System and lack of reward for men, and occupational climate and organizational system for women.
