목적: 작업관련 근골격계질환은 중요한 직업관련성 질환 중의 하나이고 작업관련 수근관증후군은 이러한 작업관련 근골격계질환 중에서도 많은 부분을 차지한다. 이 연구는 작업관련 수근관증후군의 역학적 특성에 대해 알아보고자 수행되었다. 방법: 본 연구에서는 '수근관증후군 감시체계'를 통해 2000년 6월부터 2003년 2월까지 보고 된 672례의 수근관증후군 사례를 분석하였다. 직업력이 확인된 314명을 대상으로는 직업 및 작업내용에 따라 작업관련성 수근관증후군의 비율이 어떻게 달라지는지를 분석함으로써 수근관증후군 위험요인을 조사하였다. 결과: 직업력이 확인된 314명의 환자 중 작업 관련성이 의심되는 사람은 228명 (72.6%) 이었다. 직업별로는 '단순노무종사자', '농림어업숙련자', '서비스종사자' 등에서 작업관련 수근관증후군의 비율이 여성에서 유의하게 높게 나타났으나 연령, 비만도 지수, 과거병력 등에 따른 차이는 관찰되지 않았다. 주관적 증상 중에 '손을 많이 사용한 후 심해진다'와 '손을 털면 덜해진다'라는 항목을 작업관련성 수근관증후군 환자에서 더 많이 호소하였고 다른 증상은 별다른 차이를 보이지 않았다. 작업관련성 수근관증후군 환자가 비교적 많이 노출되는 작업은 '지나치게 손을 뻗쳐서 하는 일', '손을 불편한자세로 유지하는 일' 등이었다. 결론: 전체 수근관증후군 중 작업관련성이 있다는 비율이 매우 높은 것을 확인할 수 있었다. 수근관증후군 감시체계가 작업관련성 수근관증후군의 여러 특성을 밝히는데 매우 효과적인 것으로 나타났으나 현재까지는 중재 대상을 구체적으로 특정하기에는 한계가 있다. Objectives: Carpal tunnel syndrome (CTS) is one of the most important work related musculo-skeletal diseases in Korea. However, there are few epidemiologic studies on the work-related CTS (WR-CTS). This study aimed to investigate the epidemiologic characteristics of WR-CTS in Korea. Methods: Data obtained from the "CTS Surveillance System". Physician case-reports in the surveillance were used to document patterns of WR-CTS by age, gender, occupation, sign, symptom, working history. Results: Six hundred and seventy-two cases of WR-CTS were ascertained of which 3 14 with complete information on occupational history were analyzed. It has been estimated that as many as 72% of' all CTS cases are work-related. The highest proportion of WR-CTS was observed in 'elementary occupation workers', followed by 'skilled agricultural, forestry and fishery worker'. The distributions of WR-CTS cases were similar with respect to age, obesity, and past medical history. The proportion of WR-CTS was higher in females. There was no significant difference in physical examination findings between WR-CTS and non WR-CTS cases. Repetitive work and the inappropriate hand posture seemed to be the risks for WR-CTS. Conclusion: WR-CTS is a significant public health problem. The CTS surveillance system is quite useful to elucidate the characteristics of WR-CTS, but it remains of limited use in targeting specific industries and occupations for intervention.

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.

For the study on the type of self-care status according to gender, BMI and physical self- efficacy of high-school students, this study took a census at 1,810 students of 13 high-schools at area of U and P. This study took a Chi-square to compare the type of self-care status according to gender, BMI of high-school students. The study calculate mean, standard deviation and then perform one-way ANOVA to compare physical self-efficacy of high-school students. Verifications on those was executed by Duncan with the significance level of a=.05. The conclusions of this study are followed below. At both boy and girl students: average sleeping time -6 hours, average watching TV time - 1 hour, the methods of releasing a stress : listening to music, yes or no of eating a breakfast -Taking a breakfast everyday, how often they eat snack foods - everyday, the preferred snack foods - biscuit, bread, the frequency of eating fast-foods - 1~2 per week, the preferred foods - meats, the preferred beverage - juices, the cognition on body type - a little fat body. The reason why they don't excise - having no time to excise, the reason why they do excise - To have a healthy body, the frequency of drinking alcohol - zero, the affection of smoking and drinking alcohol on studying - It seems to be, yes of no of taking medicines such as tranquilizer, sleeping drug, stimulant - No. The time of using a computer - boys (2 hours) / girls (1 hour).Boy students have a better types of self-care status than girl students in watching TV time, yes or no of eating breakfast, the preferred beverage, cognition on the body type, yes of no of taking medicines such as tranquilizer, sleeping drug, stimulant. Girl students have a better types of self-care status than boy students in the time of using a computer, the preference of snack foods, the frequency of eating fast-foods, the preferred foods, the frequency of drinking alcohol, the affection of smokingㆍdrinking alcohol on studying. At all under, normal, over-weight students: the average sleeping time - 6 hours, the average watching TV time - 1 hour, the average time in using a computer - 1 hour, the methods of releasing a stress - listening to music, yes or no of eating a breakfast : -Taking a breakfast everyday, the preferred snack foods - biscuit, bread, the frequency of eating fast-foods - 1~2 per week, the preferred foods - meats, the preferred beverage - juices. The reason why they do exercise : -To have a healthy body, the reason why they don't excise -having no time to excise, the frequency of drinking alcohol - zero, the affection of smoking and drinking alcohol on studying - It seems to be, yes of no of taking medicines such as tranquilizer, sleeping drug, stimulant - No. The frequency of eating snack-foods : low & normal - everyday / over - 1~2 times. The normal weight students have a better types of self-care status than low or over-weight in the preferences of snack-foods. the over weight students have a better types of self-care status than the normal or low-weight in yes or no of eating a breakfast, the frequency of eating snack-foods, the preferred foods, the cognition on body type. On gender, it shows a meaningful difference that the boy students are higher than the girl students in the physical self-efficacy. On BMI, it shows a meaningful difference that normal weight are higher than low & over weight in the physical self-efficacy. These results show us that we have to develop a systematic and continuous health education programs for juveniles-self that enhance upright types of self-care status and fix the wrong living and eating habits. And these results also show us that we have to prepare the types of self-care status which can be generally tested for juveniles and the development of census on the physical self-efficacy and active practice plan on self-care status.

Background: Experimental data indicate that low-flow reperfusion following prolonged cardiocirculatory arrest may aggravate early cerebral microcirculatory reperfusion disorders. We investigated the influence of cerebral reperfusion flow change to the ischemic histopathologic damage of brain tissue after incomplete forebrain ischemia in rats. Materials and method: Anesthetized Sprague-Dawley rats were undergone ligation of both internal carotid artery by microvascular clamp for 10 minutes. After release of the clamp, reperfusion was started with several different flow levels (0, 10, 20, 30, 50, and 100%) of internal carotid artery comparing to pre-clamping phase using flowmeter. After 15minutes of reperfusion, rat brains were prepared by perfusion-fixation with 3% formaldehyde. Under light microscopic examination of Hematoxylin-Eosin stained tissue slide, histopathologic damage was examined at cortex, putamen, and hippocampus regions. Categorical hisotopathologic damage scores were derived in each regions by manual counts of ischemic neurons. Result: The histopathologic damage scores were 0, 10.2±0.5, 7.6±1.5, 5.9±1.4, 5.0±2.8, 3.5±0.7, and 1.0±0.0 in control, 0, 10,20, 30, 50, and 100% reperfusion groups, respectively(p<0.05). Conclusion: Our results showed significant increment of brain histopathologic damage scores along with decreasing amount of cerebral reperfusion flow after incomplete forebrain ischemia. We believe restoration of reperfusion flow to pre-ischemic level would be a critical component in attenuation of brain ischemic damage.

This study was undertaken to evaluate an antioxidative activity of silymarin and silybin obtained from Silybum marianum against oxidation of human low density lipoprotein (LDL). The electrophoretic mobility observed apparently was higher phase for LDL oxidized by macrophages compared to native LDL. Silymarin and silybin inhibited the copper-catalysed oxidation of human LDL in a dose-dependent manner. Silymarin and silybin at the concentration of 50μM/ml also inhibited the copper catalysed oxidation of LDL induced by the cell J774 and macrophages. LDL reisolated from the cell incubation in the presence of silymarin or silybin was degraded at rates similar with native LDL. Silymarin or silybin found to be potential inhibitors against oxidation of ^125I-LDL by macrophages and endothelial cells.

Corporate's mission is to creat values in market, to develop and to prolong. Management is to evaluate, to actualize values effectively in market. The thinking of outcomes in corporate has been changed from sales amount, profits to social contribution, environmental creation. The key of innovation is performance - The idea of intellectual performance. The management based performance focuses on the effective and high quality performance in individuals of organizations. The future role of H.R.M. is to develop High Performer at last, to raise the corporate's power of value creation. The realization of corporate's mission comes true through employee's job. Accountability is composed of performance and activity. the personnel management based job classification is quite different from person related. The most important definitions are Accountability and Competency. Job based compensation is different from Seniority based compensation. Job based compensation will actualize the corporate's needs for exemple reduction of persennel expenses and motivation of young employees. Performance Management System has an important role in Pay for Performance system. Competency is another important ability and characteristics to create performance. To recruit and to transfer someone who have motivation and characteristics, to teach them skills and knowledge will be realistic and effective.
