The known risk factors for atherosclerosis include plasma low density lipoproteins (LDL)or Cholesterol, low PUFA in the diet, hypertension, and high Na intake, obesity, diabetes, lack of exercise, cigarette smoking, sugar, low fiber and nicotinic acid in the diet, sources of Protein foods, and Psychological factors. Among various dietary factors, fat is known as the most serious causative agent for atherosclerosis. The genetic factor is a18o known as an important one but is out of scope in this paper. Since atherosclerosis is a progressive disease which may develop for many years before showing any definitive symptoms, it is very important to develop preventive programs especially in the country like Korea that is not quite overdevelopted as some western countries. In this paper all the factors mentioned above were reviewed and the dietary suggestion were made on the basis of the content of polyunsaturated and saturated fat in the diet to prevent or/and to cure this disease. Most of the available data on diet therapy with emphasis. on P/S ratio were tabulated together. after tile patient's habitual dietary intake is analized the guidelines of personalized fat-controlled diet can be recommended. It is of utmost importance to develop Korean diets for beth prevention and cure of atherosclerosis emphasizing individual eating habit in the near future which can be more Practicaly used both at home and in the hospital.

This study was done to compare the nutritional status of antioxidant vitamins between college women smokers and nonsmokers. Dietary intakes and serum levels of antioxidant vitamins were determined in 33 smokers and 42 nonsmokers residing in the Seoul area. Dietary intakes of vitamin A and C were determined by a quick and convenient dietary intake method. Serum vitamin C level was measured by 2, 4-dinitrophenylhydrazine method and serum levels of vitamin A and E were measured by HPLC. The mean A intake of nonsmokers and smokers was 504.3$\mu$gR.E./day and 450. 4$\mu$gR.E./day and the mean vitamic C intake of nonsmokers and smokers was 51.6mg/day and 50.2mg/day, reapectively. There was no difference in the dietary intakes of antioxidant vitamins between smokers and nonsmokers. The serum vitamin A level, 0.71mg/1 in nonsmokers was not significantly different from that of 0.74mg/1 in smokers. However, the serum vitamin C level, 7.94mg/1 in smokers was 15% lower(p$\ll$0.05) than that of 9.30mg/1 in nonsmokers. The serum vitamin E level, 18.15mg/1 in smoders was also 34% lower(p$\ll$0.05) than that of 27.58mg/1 in nonsmokers. There was no significant correlation between dietary intakes and serum levels of vitamin A and C for both smokers and nonsmokers. These results suggest that cigarette smokers need more dietary intakes of vitamin C and E than do nonsmokers to reach the same serum level.

This study describes the manufacturing method of antioxidant filter and evaluate the reduction of free radical and biological activity from mainstream smoke. When we used spray-brush for the application of antioxidant solution to the filter, cv(coefficient of variation) levels of antioxidant added to filter ranged within 3 %, which means stable and constant feeding process. 0.3~0.5mg per cigarette of antioxidant were sprayed to acetate and active carbon part in the filter plug, respectively. It was considered that the use of antioxidant added filter resulted in the reduction of the gaseous compounds of free radicals from 17 % to 19 % in the mainstream smoke. Variation for removal efficiency of free radical in antioxidant filter added to acetate part was more pronounced than that of filter added to active carbon part. Smoking deliveries of tar, nicotine for the antioxidant added filters were similar when comparing to the non-antioxidant added filter, but the delivering amounts of isoprene were significantly reduced. The estimation of consumed GSH(glutathion) showed that the gaseous toxicity of the antioxidant added filter was 14 % ~ 23 % lower than that of non-antioxidant added filter. No significant differences were observed for the total taste quality in sensory evaluation.

We evaluated the status of Clonorchis sinensis infection and potential risk factors among residents of riverside areas (Geumgang) in Muju-gun, Jeollabuk-do (Province), Korea. From January to February 2010, a total of 349 (171 males, 178 females) stool samples were collected and examined by the formalin-ether concentration technique. Also, village residents were interviewed using questionnaires to obtain information about C. sinensis infection-related risk factors. Overall egg-positive rate of C. sinensis was 13.2%. Egg-positive rates were significantly higher in males, farmers, and residents who had lived there more than 20 years, and in residents who had eaten raw freshwater fish than in opposite groups, respectively. However, there was no significant difference between age groups, education levels, cigarette smoking, alcohol drinking, health status, past history of infection, and experience of clonorchiasis medication and examination. Logistic regression analysis was performed to determine risk factors for clonorchiasis. On univariate analysis, the odds ratios for males, farmers, those who had lived there more than 20 years, and who had eaten raw freshwater fish were 2.41, 4.44, 3.16, and 4.88 times higher than those of the opposites, respectively. On multivariate analysis, the odds ratio of residents who had eaten raw freshwater fish was 3.2-fold higher than that of those who had not. These results indicate that residents living in Muju-gun, along the Geum River, Korea, have relatively high C. sinensis egg-positive rates, and the habit of eating raw freshwater fish was the major factor for the maintenance of clonorchiasis.

This study was conducted to investigate the prevalence rate of low back pain during past one year and its risk factors. The data were collected from 1,384 manufacturing factory workers from March 1, 1992 to August 30, 1992. The results obtained were as follows: 1. The one year prevalence rate of low back pain by manufacturing company was 38.4% in textile manufacturing, 35.2% in concrete reenforcement, 31.0% in cigarette and 26.1% in metal part(P<0.01). 2. In textile manufacturing, age groups with high prevalence rate of low back pain were 30's(36.8%) and 40's(36.4%) (P<0.05), and the one year prevelence rates of low back pain by marital state were 34.9% in married workers and 28.5% in unmarried(P=0.0511). 3. The one year prevelence rates of low back pain by job part are 35.0% in labor workers and 26.1% in clerical(P<0.05), and by work hour per day it was 34.9% in 9 or more and 28.9% in 8 or less(P<0.05). 4. The highest group of low back pain by work posture was 43.5% in 'lifting and transfering materials', and it by fitness of chair was 56.0% in uncomfortable one, and by height of working board was 33.6% in low working one. 5. In logistic regression analysis, significant determinants with low back pain were marital state(p<0.05), work hour per day(P<0.05), height of working board(P<0.01), and work posture(P<0.01).

Objectives: The purpose of this study was to examine the relationship of meeting the recommended levels of physical activity (PA) with health status and preventive health behavior in adults. Methods: A total of 5630 adults 18 years of age or older were included in this study. PA was assessed using a series of questions that categorized activities based on their metabolic equivalent values and then categorized individuals based on the reported frequency and duration of such activities. Participants reporting 150 minutes or more of moderate-intensity PA per week were considered to have met the PA guidelines. Multiple logistic regression was used to model the relationships between meeting PA guidelines and health status and preventive health behavior, while controlling for confounding variables. Results: Overall, 53.9% (95% confidence interval [CI], 51.9 to 55.9%) of adults reported meeting the recommended levels of PA. Among adults with good general health, 56.9% (95% CI, 54.7 to 59.1%) reported meeting the recommended levels of PA versus 43.1% (95% CI, 40.9 to 45.3%) who did not. Adults who met the PA guidelines were significantly more likely not to report high cholesterol, diabetes, chronic obstructive pulmonary disease, arthritis, asthma, depression, or overweight. Furthermore, adults meeting the PA guidelines were significantly more likely to report having health insurance, consuming fruits daily, consuming vegetables daily, and not being a current cigarette smoker. Conclusions: In this study, we found meeting the current guidelines for PA to have a protective relationship with both health status and health behavior in adults. Health promotion programs should focus on strategies that help individuals meet the current guidelines of at least 150 minutes per week of moderate-intensity PA.

This study was conducted to investigate the effects of passive inhalation of cigarette smoke and the correlation between change of flicker value and active or passive smoking in poorly ventilated room. Forty five male students were tested by divided into four experimental groups composed of active and passive smokers and three control groups. Each four experimental groups were exposed to smoke for Two hours in enclosed room. Vital capacities, flicker values, blood carboxyhemoglobin levels and carbon monoxide concentration in room air were estimated before, during and after the exposure, and amounts of smoking or smoke exposure during two hours were also noted. The results obtained were as follows; 1. Concentration of carbon monoxide in air and increase of blood carboxyhemoglobin level (% COHb) were positively correlated with smoking amount. 2. Increase of blood carboxyhemoglobin in passive smokeres, in average, were about seventy six percent of that in smokers, as 2.2% vs. 2.9%. 3. Comparison with published data showed that Peterson's equation gave most similar result to this study in estimation of increase of blood carboxyhemoglobin level. 4. During the exposure, flicker values fell steadily in both experimental groups and control groups as time passed. Flicker values were, however, elevated again in experimental groups after exposure, despite the fact that values still fell in control groups. 5. Blood carboxyhemoglobin and flicker value were negatively correlated and this correlationship was stronger in passive smoker than in active smoker. 6. Multiple regression equation between flicker value and exposure time and blood carboxyhemoglobin level was expressed as: Flicker value=41.6-0.2 COHb%-0.9Hour, 7. In general, it is suggested that biological criteria would be more preferrable than chemical criteria in establishment of statutory limitation of smoking in enclosed spaces.

Essential oil in tobacco leaves influences the taste and aroma of cigarette smoke and is important to tobacco quality. This study was conducted to investigate the change in the level of essential oil components during flue-curing process of two flue-cured tobaccos, NC82 and KEl14. Flue-curing process was divided by six steps; harvest stage, the end of yellowing stage, the middle of color fixing stage, the end of color fixing stage, the middle of midrib drying stage, full-cured stage. NC82 in each stage contained 0.28%, 0.30%, 0.35%, 0.36%, 0.40% and 0.42% essential oil, respectively, and KF114 were 0.29%, 0.31%, 0.34%, 0.36%, 0.39% and 0.41%, respectively. Almost all hydrocarbons on the basis of relative peak area were gradually increased in two varieties with curing, neophytadiene content in them was highest at the full-cured stage. Most of alcohols and esters with curing showed a declining trend, but benzyl alcohol was increased in two tobaccos. Ketones were largely increased at the midrib drying stage during the curing process, especially, the most largely increasing constituent was $\beta$-damascenone among them. The content of 2-butylterahydrofuran, heterocyclic compounds, was largely increased at tile color fixing stage. There was no considerable difference between NC82 and KFl14 at the GC profile of essential oil and the pattern of each components during flue-curing process.

This study was conducted to evaluate the prediction of sensory characteristics of smoke from the leaf chemical compounds and characterize leaf chemical components for the best tobacco taste's leaves in oriental tobacco. For analytical and sensory evaluations, seventy two grades were used. Sensory evaluation of tobacco smoke for six attributes were scored on fifteen-point scale by $10{\sim}14$ expert panels trained to estimate smoking quality quantitatively. The major leaf chemical compounds to predict the sensory characteristics of smoke were ether extract for tobacco-like, nicotine for impact and total nitrogen/nicotine ratio for irritation, and total sugar for off taste & odor. Within ${\pm}20%$ range of difference, the predictable probabilities of sensory characteristics of smoke from the leaf chemical compounds were 87.5 % for off taste & odor and $94.4{\sim}98.6\;%$ for tobacco-like, impact and irritation. As a result of K-means cluster analysis on the basis of tobacco taste, the desirable leaf chemical compound contents were $5.9{\sim}8.3\;%$ in ether extract, $1.35{\sim}2.27\;%$ in nicotine and $1.17{\sim}2.24$ in total nitrogen/nicotine ratio. This study suggest that the some regression equations may be useful to predict the sensory characteristics of tobacco smoke with a few selected leaf chemical compounds in oriental tobacco and to select the oriental tobacco leaves by means of enhancing the tobacco taste of cigarette.
