Recently, as the infection rate of Fasciola sp. has increased, many people have to understand its economic and public health significance and take more effective control measures. Such harmful effects as economic loss and public health problems should be reduced by proper managements against Fasciola infections. The author describes the economic loss and methods of control of Fasciola infection in Korea, with special references. The economic loss is reported below, also control measures which would help to break the chain of events in the life cycle of Fasciola sp. were proposed as follows. 1. The infection rate of Fasciola sp. in Korean cattle appeared to be 30.9% and the economic loss was estimated as 1,101,880,000 won for loss of meat, 246,928,599 won for loss of the liver, and 153,159,500 won for the annual loss of milk which reached a total of 1,501,968,000 won. 2. For the control of Fasciola infections of animal and human, (a) mass treatment of infected animals, (b) sanitary treatment of animal(herbivor) faeces containing Fasciola eggs, (c) molluscidal measures of the intermediate host, (d) protection of herbivors from feeding grasses contaminated with Fasciola metacercariae, (e) prohibition of human from eating vegetables contaminated with Fasciola metacercaeiae, and (f) prohibition of human from eating raw or improperly cooked liver or intestines of herbivors were recommended.

포괄적인 산업장 보건관리를 위해 1987년부터 개발하여 사용되어오던 포항제철 산업장 보건관리 전산시스템의 수정작업을 1992년 5월 1일에 착수하여 1994년 3월에 완성하였다. 포항제철 산업장 보건관리 전산시스템의 주요 구성분야는 건강진단분야, 작업환경분야 및 개인적 인사분야로 이루어져 있으며, 수정작업시 기존 시스템이 서로 다른 분야와의 연결이 어려웠던점을 보완하여 연결이 서로 용이하게 이루어 질 수 있도록 하는데에 역점을 두었다. 우선 건강관리분야에는 적정배치를 가능하게 하는 채용건강진단영역 및 건강이상자, 휴·복직자와 장애자를 관리할 수 있는 질병자관리영역이 있고, 개인 인사분야 및 유해물질정보가 기록되는 작업환경분야에 의해 일반, 성인병 및 특수건강진단대상자가 자동 선정되어 이루어지는 건강진단영역이 있으며, 동시에 작업환경분야에 의해 해당보호구 지급관리가 이루어질 수 있도록 하였다. 이외에도 각 분야에 관련된 보고서 작성, 통계 및 분석이 가능해져서 시간의 경과에 따른 질병발생의 변화를 관찰하며 예방사업을 포함한 산업장 보건사업의 평가로 포괄적인 보건관리가 이루어 질 수 있는 기능을 갖추도록 하였다. POSCO Health Care Center has collected health and environmental data using computerized system since 1987. One of the important roles of Industrial Health Care Center is to provide a comprehensive occupational health care, including therapeutic medical care, periodic medical examination and industrial hygiene control for the prevention of work-related illnesses. To strengthen the functions of an occupational health surveillance system, lots of effort have been made to modify and improve the existing computerized system since May, 1992, and it is scheduled to be completed by March, 1994. The modified POSCO Computerized Occupational Health Surveillance System(PCOHESS) contains three major areas: health care, environmental monitoring, and personal information. The linkage among three areas, lacking in the previous system, was emphasized in PCOHESS. The area of health care assists the management of preplacement examination data as well as the diseased and disabled data, and it will facilitate the preplacement for new employees and will efficient care for the diseased and disabled. Environmental and personal sampling data, and personal information data, such as age, education and jobcode etc, that are linked to each employee, can assist the health care professionals to decide the type and time of medical examination and to periodically supply proper protectors. Data collected from the time of one's employment until his/her retirement can be used for the epidemiologic surveillance which will enable to evaluate the employee's health status related to his/her work environments, and to identify the places that are necessary to be improved.

This study was examined to find out asbestos exposure level the factors which affected the level at asbestos abatement sites. We visited a total of thirteen building demolition sites(3 apartments, 3 schools, 4 stores, and 3 houses) were visited to collect samples and related data from August to November, 2006. The results of this study were as follows 1. The results of an analysis of bulk samples to identify types of asbestos at the asbestos abatement sites showed that the kinds of the asbestos detected were chrysotile by 50.0%, were tremolite by 2.6%, and were the contents of chrysotile by 3 to 20%. 2. The geometric mean concentration of asbestos was 0.007f/cc(range 0.001-0.34 f/cc) and its geometric standard deviation was 5.83. Of the samples, however, 12 exceeded the Korean Occupational Exposure Limit(0.1f/cc). 3. Of the materials, textile material had the highest concentration with geometric mean of 0.016f/cc. When asbestos-containing materials were removed using T type tools, the geometric mean concentration of asbestos was 0.061f/cc. The level by this method was much higher than by other removal methods. In analysis by the type of building, the geometric mean concentration of asbestos in stores was 0.042f/cc and was higher than in other buildings. 4. The Poisson regression analysis was applied to find out the factors that affect the airborne asbestos concentration. As a result of the analysis, removal using a T type tool was the most important factor affecting the asbestos concentration(p<0.01). In conclusion, the airborne asbestos concentration(geometric mean) in asbestos abatement sites was 0.007f/cc(0.001∼0.34f/cc), and 12(14.6%) of all samples were over the 0.1f/cc. These results showed that asbestos abatement workers have been exposed to the high level of airborne asbestos because they have not been keeping asbestos removal rule. In accordance with increases of the number of building demolition sites, the better government regulation on asbestos abatement methods should be made and be performed well at building demolition sites.

Objectives: We investigated the effects of changes in obesity and life style factors, such as cigarette smoking, alcohol drinking, and exercise, on the changes in blood pressure and serum cholesterol among Korean men. Methods: This study included 7,205 healthy male employees in the steel manufacturing industry. Each subject underwent health examination in 1994 and was re-examined in 1997. The study subjects were classified into four categories, according to changes in body mass index (BMI) (loss; stable; mild gain: severe gain), cigarette smoking (quitter; nor-smoker; smoker continued; smoker started), alcohol drinking (quitter; non-drinker; drinker continued; drinker started) and exercise (more exercise; continuous regular exercise; continuous irregular or no exercise; less exercise), respectively. We evaluated the relationship between the categories of change in those independent variables and the changes in blood pressure and serum cholesterol, adjusted for BMI in 1994 and age by analysis of variance. Results: The change in systolic blood pressure was positively associated with the changes in BMI (p<0.001) and drinking (p=0,001), but negatively with smoking (p=0,004), compared to the first category of each independent variables. The systolic blood pressure was significantly less increased in the continuous smoking group than quitter or hon-smoker. The changes in diastolic blood pressure and serum cholesterol appeared to have statistically significant linear relationships only with the change in BMI. The change in exercise showed a marginal significance with diastolic blood pressure (p=0.088). Conclusions: These prospective data emphasize the importance of obesity as a determinant of the changes in blood pressure and serum cholesterol. In addition, the changes in smoking and drinking habits can affect systolic blood pressure.

This study was conducted to examine lipid, blood pressure, glucose, and health behavior of normal people and obese people. The normal people and obese people received health examination in K and D hospitals. The normal group was composed of 243 men and 191 women, while the obese group was composed of 194 men and 190 women. Data were collected from May, 1999 to Decomber, 1999. The results of this study are summarized as follows. 1. Male was 56.0% and female was 44.0% in the normal group, while male was 50.5% and female was 49.5% in the obese group. In the case of age, in the normal group 24.9% was in twenties, 15.4% was in thirties, 16.4% was in forties, 18.9% was in fifties, and 24.4% was in sixties and over. In the obese group 14.1% was in twenties, 16.4% was in thirties, 21.4% was in forties, 23.7% was in fifties, and 24.4% was in sixties and over. 2. According to the distribution of lipid, blood pressure, and glucose by sex, the normal group displayed significant difference in BMI, triglyceride, high density lipoprotein (HDL) cholesterol, SBP, and DBP, while the obese group showed significant difference in BMI, triglyceride, SBP, and DBP. 3. In the case of the distribution of lipid. Blood pressure, and glucose by age, the normal group revealed significant difference in BMI, total cholesterol, triglyceride, low density lipoprotein (LDL) cholesterol, SBP, and DBP, shile the obese group displayed significant difference in BMI, total cholesterol, SBP, and DBP. 4. According to health behavior of the normal group and the obese group by sex, male showed significant difference in favorite food (p<0.05), while female displayed significant difference in eating habit (p<0.05). 5. The factors which significantly influenced BMI were SBP (p<0.05), total cholesterol (p<0.001), triglyceride (p<0.001), times of eating meat (p<0.05), and exercise (p<0.05). As seen in the above results, the obese group showed higher lipid, blood pressure, and glucose than the normal group. It seemed that especially, the lack of exercise, the unbalanced diet, and eating of meat affected obesity. Drinking and smoking had harmful influence on lipid, blood pressure, and glucose, It appeared that adequated exercise helped them prevent geriatric disease. It can be said that the diseases related to obesity will increase due to change in socio-economy and diet. It is important to prevent obesity through clinical test related to obesity and heal education.

This stud was carried out to evaluate health effects of noise using THI(Todai Health Index) from July 15 to August 30, 2001, 696 industrial workers whose health was managed by korea industrial Health Association were selected as subject of this study. The results were as follows ; 1. Study subjects, 696 workers, were divided into three groups, non-exposure group, 85-99dB group and 100dB≤group. the group who was exposed to high noise level(100dB(A)≤) showed the higher complain level than the other two groups who were exposed to less than 100dB(A). 2. Workers exposed to more than 100dB(A) displayed significantly different complaint level in aggressiveness scale, digestive scale and nervousness scale. 3. Depending on complaint level by all characteristics and noise level, workers exposed to more than 100dB(A) showed higher level in high aged workers, female, those who worked for a long time, heavy drinker, and heavy smoker and sitting workers. Form the results, we suggest that industrial hygienists have to formulate a comprehensive health management system for high level noise exposure workers included good life style, mental health, and noise deafness protection measures in order to technically control the health of noise exposure workers.
