Purpose: In Ulleung island, emergency medical transport by helicopter is very important. So, we analysized our experience with emergency medical transport by helicopter for 4 years and we were compared our data with other data for 1997-2001. Therefore we need to research public health development direction. Method: We analysized patient's medical record for 4 years. Result: During 4 years, 104 transports were done and 130 patients were trasported to tertiary hospital center, there was more increased than that from 1997 to 2001. Helicopters from Pohang coast guard, Donghae coast guard, Navy, and 119 rescue etc. were used, but 119 rescue transport was decreased more and more. The 60's patients was most, 22.3% and teenager's and 80's patients was lowest. The male was 65% but the female was increased more and more annually. In addition, the older patients was the more portion of female patient. The transport was concentrated in daytime. The traumatic patient was much in winter period. The cerebrovascular accident was 1st cause of patient and fracture was many also. Conclusioon: Except Fire service's helicopter, the other helicopter was not apt to emergency medical tansport. But Fire service's helicopter was not used commonly because Fire service's helicopter was in Daegu, so distant and time consumed. As a result, emergency medical transport helicopter is needed in east coast like Fire service's helicopter. In addition, trauma prevention education and public health education for hypertension and diabetes will be essential and public health system in Ulleung island will be prepared for aging society.

This study was carried out to obtain the basic data for the prevention of chronic poisoning by organic phosphorous pesticides and to estimate the normal range of plasma cholinesterase activity level for Korean agricultural workers. The 285 agricultural workers were randomly selected for the study in Jungup Gun, Jeonbug Province, 135 persons of them were tested in the period of pre-exposure of organophosphorous pesticides (April 1981) and rest of them were tested after exposure(August 1981). Cholinesterase activity levels were measured by the Micro-method of Takahashi Hiroshi. Major findings are as following: 1) There is significant difference in plasma cholinesterase activity levels between the pro-exposed and post exposed group(p > 0.01). Mean values of plasma cholinesterase activity levels were $7.60{\pm}1.74{\mu}M/20{\mu}{\ell}$/hr. in the pre-exposed group and $6.23{\pm}1.59{\mu}M/20{\mu}{\ell}$/hr. in the post-exposed group. 2) Plasma cholinesterase activity in Korean agricultural worker could be estimated $7.30-7.90{\mu}M/20{\mu}{\ell}$/hr. with 95% confidence interval.

This study was performed to investigate the prevalence and its related factors on the Clonorchis sinensis(C.S.) of inhabitants at Goksung-gun, Chollanam-do. After the population was stratified by gender, age, resident area, 651 residents living in eight villages were sampled by cluster sampling method. We interviewed the subjects to survey the various characteristics using the questionnaire, and examined stools to confirm the infection of C.S. from November to December, 1998. The prevalence of C.S. was 19.0%. The factors related with the infection of C.S. were male(adjusted odds ratio, of female=1.71, 95% confidence interval=1.07-2.72), 45-64 year old group(aOR of under 45 year old group=2.16. 95% CI=1.21-3.85), above 65 year old group(aOR of under 45 year old group=2.34, 95% CI=1.31-4.15), basin villagers(aOR of inland villagers=2.34, 95% CI=1.31-4.15), current drinker(aOR of nondrinker=1.83, 95% CI=1.12-2.98), those who took raw fish(aOR of persons who didn't it or take cooked fish=2.09, 95% CI=1.21-3.88) and persons who know the infection status(aQR of the persons who didn't know it=0.57, 95% CI=0.37-0.89). In conclusion, these results suggest that several life styles such as ingestion of raw fish, drinking habit. So we think that it is necessary to set up the efficient management programs for the treatment and prevention of C.S. infection.

Air pollution associated with the $NO_x$ emission from the ship engines is becoming one of the major environmental concerns these days. As the regulations on ship pollutants are strengthened, the wet absorption method, for controlling complex pollutants in a confined space, has the advantage of simultaneously removing various pollutants, but the low solubility of nitrogen monoxide is drawback. In this study, for improving existing denitrification scrubber system, NO oxidation process by hydroxyl radical produced from irradiating UV light on $H_2O_2$ is suggested and the $H_2O_2$ decomposition rates and hydroxyl radical quantum yields were measured to find the optimum condition of $H_2O_2$ photolysis reaction. As a result, the optimum quantum yield and photolysis rate of $H_2O_2$ were 0.8798, $0.6mol\;h^{-1}$ at 8 W, 2 M condition, and oxidation efficiency of 1000 ppm NO gas was 40%. In batch system, NO removal efficiency has a range of 65.0 ~ 67.3% according to input gas concentration of 100 ~ 1500 ppm. This results indicate that the scrubber system using hydrogen peroxide photolysis can be applied as air pollution prevention facility of ship engines.

The purpose of this study was to analyze the reasons and mean age for tooth extraction among patients living in Busan city. The researcher observed 1,119 patients' teeth extracted due to dental caries, periodontal disease and other reasons. This study examined the reasons for tooth extraction by age, sex, and tooth-kind. The reasons for tooth extraction were dental caries, periodontal disease, eruption problems and others. The obtained results were as follows; 1. Among the reasons for tooth extraction, dental caries accounted for 25.9%, periodontal disease 56.5%. 2. Periodontal disease was the main reason for tooth extraction and continued throughout life irrespective of sex. However dental caries was remarkably increasing in those aged 30 years old and under. 3. In the extraction of permanent teeth, males outnumbered females while upper teeth did lower teeth. 4. Although the third molars were most extracted in all kinds of teeth, the main reasons for the extraction were eruption problem. 5. The mean age of the tooth extracted was 47.9 years in both sexes for the mandibular first molars and the mandibular first molars had the shortest life except third molars of total teeth. The mandibular canines had the longest life of total teeth. Because dental caries and periodontal disease are the main causes of tooth extraction in Korea, the dental health policy should be focused on the prevention and treatment of these two diseases in the government level.

The purpose of this study was to make a comparative analysis of the oral health knowledge, attitude and awareness of students in schools equipped with and without a dental clinic in the city of Gwacheon. The subjects in this study were 782 students in that area. Out of them, 398 students attended a school furnished with a dental clinic, and 384 attended another school that wasn't equipped with a dental clinic. It's ultimately meant in this study to contribute to boosting the managerial efficiency of a school dental clinic and stepping up the development of quality oral health programs. The findings of the study were as follows: 1. When the students from the two schools were compared in terms of oral health knowledge, there wasn't any significant gap between the two groups in general. One difference was that the students from the school furnished with a dental clinic were more aware of presentive treatment provided by a dental clinic than the others from the other school. 2. As for attitude to oral health, there was no significant difference between the two in every regard except daily mean frequency of having a snack. 3. Regarding oral health belief, the students from the school equipped with a dental clinic had a better oral health belief in every aspect including health status, importance of oral health and interest than the others, and the difference between the two was significant. 4. Concerning perception of school dental clinic, the students from the school furnished with a dental clinic were better cognizant of it. As to the necessity of it, both groups viewed it as necessary for the prevention and treatment of dental caries. In terms of preference for school dental clinic, the students from the school furnished with a dental clinic had a greater preference for that.

This study aims to measure oral health knowledge and practice level among dental clinic patients, and examine their relationships with decayed, missing and filled teeth (DMF) index and the oral health-related quality of life (QOL). Empirical data have been collected from 311 patients through structured questionnaires and dental examinations conducted in Busan area. According to the analysis of causal relationship, oral health knowledge turned out to have a direct effect on oral health practices, which exerted both direct and indirect effects on DMF index and oral health-related QOL. While DMF index directly affected the oral health-related QOL, oral health knowledge proved to have only an indirect effect on DMF index and oral health-related QOL, mediated by oral health practices. Considering all these findings, effective oral health education and other intervention programs should focus on motivating people to participate in the active practices of desirable oral health behaviors, which will lead to the prevention of oral diseases and the subsequent improvement in the QOL.

HbA1c was recently adopted as a reliable indicator for screening diabetes. This study investigated the ability of nutrition consultation to prevent diabetes in overweight women (BMI 23 $kg/m^2$ or more) using HbA1c as an indicator. Twenty overweight and obese women (with $HbA1c{\geq}5.7$%) completed the 12-week nutritional study, with individual and personalized nutrition counseling performed every 2 weeks. The main study guidelines involved the following: 1) reducing the intake of high fat foods and alcohol, 2) consuming a large amount of vegetables, 3) reducing the intake of simple sugars and empty-calorie foods, and 4) increasing physical activity to ${\geq}30$ min/day. Anthropometric (height, weight, BMI, body muscle (kg), body fat (%), waist and hip circumference, blood pressure) and biochemical parameters (fasting blood sugar (FBS), HbA1c, lipid profiles, hs-CRP) were measured before and after the nutrition consultation. After 12 weeks, the HbA1c<5.7% group had significant decreases in BMI, WC, HC, WHR, HbA1c, hs-CRP and also dietary intake of energy (P<0.01), carbohydrates, lipids (P<0.01), proteins (P<0.01) and cholesterol was significantly decreased (P<0.05). In the HbA1c ${\geq}5.7$% group, HbA1c, TC, LDL, NON-HDL, hs-CRP and dietary intake of energy, carbohydrate, lipid, protein, and cholesterol significantly decreased (P<0.05). These results suggest that nutrition consultation effectively helps to prevent diabetes in overweight and obese women after applying HbA1c standards. Overall, the improvement in all markers measured suggest that HbA1c is a good indicator for blood glucose regulation, helping to prevent diabetes.
