The aim of this study was to determine the association between, smoking, exercise, sex, and dietary carotenoids ($\alpha$-carotene, $\beta$-carotene, $\beta$-cryptoxanthin, lutein + zeaxanthin, lycopne) intake in Korean middle-aged adults. Food-frequency questionnaire were analyzed from 304 healthy adults (115 men, 189 women) aged 20 - 59. The self-administered questionnaire contained subject s habitual diet and alcohol intake were the previous 3 months. Data on frequency of 102 foods, including vegetables, fruits, beverages and legumes were analyzed. Total dietary carotenoids intake were 27.13 $\pm$ 3.09 mg/d for men and 26.71$\pm$ 2.82 mg/d for women. It was found that smoking had no significant contribution to the dietary intake of carotenoids. Among other lifestyle factors that had significant correlation was the amount of exercise time. The increases in exercise time was associated with increase in carotenoids intake (r= 0.121, p : 0.04). The major contributors of $\alpha$-carotene and $\beta$-carotene were carrots consumed as single-food item or carrot juice. Lutein and Zeaxanthin intake mainly came from spinach and most lycopene intake was derived from tomato products not fresh tomatoes. Persimmon was the major contributor of $\beta$-cryptoxanthin. These findings provide valuable information on understanding the unique pattern of dietary intake of Korean, which might help identify the risks for developing various diseases.

본 연구는 고혈압전단계자들에 대한 지속적인 건 스트레치시 시간에 따른 생리학적 반응을 분석하여 정상혈압자와 고혈압전단계자에 대한 EPR의 한 요소인 기계적 수용기가 혈압 및 혈역학 반응에 어떠한 영향을 주는지를 검토하였다. 그 결과, 안정 시와 시간에 따른 혈압 반응은 고혈압전단계자에 있어 SBP, MAP가 평균 20sec에서 통계적으로 가장 높은 경향을 보였으며(p<0.05), 정상혈압자에서는 SBP, DBP, MAP가 평균 45sec에서 가장 높은 경향을 보였다(p<0.05). 이는 고혈압 전단계자의 지속적인 수동적 건 스트레치 시 정상혈압자에 비해 Group III mechanoreceptors의 역기능에 따른 상승된 혈압 반응이 초기에 나타내었다고 사료된다. 또한 혈역학 반응에서 안정 시와 비교하여 지속적인 수동적건 스트레치 시 고혈압전단계자에서의 HR, SV, CO, TPR 모두 유의한 차이를 보이지 않았으나 정상혈압자에서 SV, CO가 통계적으로 유의한 차이를 보였다(p<0.05). 이는 CO, SV, HR, TPR이 정상혈압자에 비해 고혈압전단계자에 있어 높은 경향을 나타내었지만, 혈역학 반응은 본 연구를 통해 차이를 보이지 않아 앞으로 연구가 필요할 것으로 사료된다.

Objectives: This study was designed to investigate the relationship between metabolic risk factors, Index of Nutrition Quality, and the dietary quality index score of Korean adults. Methods: The subjects were 18,652 Korean adults aged 19 years or older (7,899 males, 10,753 females) who participated in the 2016-2019 Korea National Health and Nutrition Examination Survey. Subjects were divided into normal, pre-metabolic syndrome, and metabolic syndrome (MetS) groups according to the number of their metabolic risk factors. Data were analyzed using the SPSS program. Results: About 44.7% of men in the MetS group were at least college graduates (P < 0.001), whereas 52.0% of women in the MetS group were middle school graduates or lower (P < 0.001). The frequency of fruit and dairy products intake tended to decrease as the number of metabolic risk factors increased in both men and women (P for trend < 0.001). As the number of metabolic risk factors decreased, the frequency of grain intake tended to decrease in men (P for trend < 0.001) while the frequency of intake of red meat (P for trend = 0.001), poultry (P for trend < 0.001), and eggs (P for trend < 0.001) decreased in women. The total scores of Diet Quality Index-International (DQI-I) (men P < 0.001, women P < 0.01) and Korean Healthy Eating Index (KHEI) (men and women P < 0.001) were significantly lower in the MetS group compared to the other groups, and the total score of DQI-I and KHEI tended to decrease as the number of metabolic risk factors increased. Conclusions: Dietary quality evaluation using various indices can provide more information on the dietary problems related to metabolic risk factors. Nutrients and foods that have been confirmed to be related to metabolic risk factors can be used to develop dietary guidelines for the nutritional management of metabolic diseases.

Vitamin E in the body system plays an important role in preventing chronic diseases by decreasing the oxidative stress by free-radicals. However, there are not enough researches on analyzing the primary factors affecting vitamin E levels in the blood in Korean adults. Therefore, the purpose of this research was to examine blood tocopherol levels and the primary factors affecting the status. A complete lifestyle survey was performed on 314 Korean adult men and surveyed their smoking, drinking and exercising habits. The average plasma level of ${\alpha}-\;and\;{\gamma}-tocopherol$ showed similar mutual relations with plasma total cholesterol (TC), triglyceride (TG), or low density lipoprotein cholesterol (LDL-C) levels (p<0.001). Plasma ${\alpha}-tocopherol$ level of the subjects did not show any difference as smoking, drinking and exercising habits changed. However, ${\gamma}-tocopherol$ per TG showed much lower figure in smokers than non smokers (p < 0.05). Amongst diet factors, plasma ${\alpha}-tocopherol$ level showed negative correlations with Vitamin E intake, while ${\gamma}-tocopherol$ level showed positive correlations with Vitamin E intake. Erythrocyte superoxide dismutase (SOD) activity and plasma tocopherol showed negative correlations, and catalase activity and plasma ${\alpha}-tocopherol$ showed positive correlationship. The level of cell DNA damage of Iymphocyte and plasma ${\alpha}-\;or\;{\gamma}-tocopherol$ showed negative correlations. As a result of this research, the factors that affect Korean adult men's plasma ${\alpha}-tocopherol$ level are plasma TG, LDL-C and cell DNA damage in Iymphocyte, while the factors that affect ${\gamma}-tocopherol$ level are plasma TG, LDL-C and vitamin E intake based on multiple regression analysis. These findings implies that the level of different types of tocopherol depends on slightly different factors. A further research is needed on the factors involved in the differentiation of the types of tocopherol.

This study was conducted because of the investigator's concern for the high incidence and fatal nature of cancer in prime years of human life. The purpose of this study was to investigate risk factors on compilance for preventive health behavior of cancer. The data on which the analysis was based come from a survey of 828 married men & women, 40-59 years old. The instrument of the study were 'Health Belief Model' by Becker. The Data was analyzed using X--test, t-test, ANOVA, Pearson's Correlation Coefficient, Stepwise Multiple Regression. The followings were the result; 1. The examined group had a higher scores than the non-examined group in health belief variables. (p<0.001) 2. The higher level of health belief variables, the higher level of compliance for preventive health behavior is. (p<0.001) 3. The Stepwise Multiple Regression of compliance for preventive health behavior on the variables in the health belief model; Approximataly 65.5% of the variance of compliance for preventive health behavior was accounted for by health concern, susceptibility and barriers in combination. This meant that other factors seemed to influence preventive health behavior since the linear combination of variables failed to explain the remaining 34.5% of preventive health behavior of cancer. It tended to cost doubt on the usefulness of 5 variables in this model. Therefore further study to investigate the influential factors preventive health behavior of cancer is necessary.

Objectives : To help develop strategies to cope with the changes arising from the rapid aging process by predicting the determining factors of intention to actual use of the charged long-term care services for elderly as perceived by the middle aged who play the major role of supports. Methods : Subjects were the parents (men 177, women 507) in their 40s of the students selected from a university of Busan city. A questionnaire survey was conducted for 4 weeks in October 2003 about the knowledge for long-term care service, the intention of actual use, and the preferences about the type of service suppliers. Data analysis was performed with frequency, chi-square test, and t-test using SPSS program (ver 10.0K), along with data mining using decision tree of Enterprise Miner V8.2 by SAS. Results : About half of the subjects (53.7%) had the actual experiences of elderly supports. Intentions to use the charged services were relatively high in home visiting nursing care service (40.1%) and long-term care facilities service (40.4%), and were influenced by previous knowledge about the services. The intentions were stronger in women, those with higher education, and those with greater income levels. Actual elderly supports were mostly (80%) done by women, and the perceived burdens for the supports were bigger in women and those of lower socioeconomic level. Desired charges were about 10,000 won for the bath service, 20,000 won for the rests services per day, and about 500,000 won for the long-term care facilities service per month. From the result of decision tree analysis, the job professionalism was the most important determining factor of intention to actual use of the services with validation as $63{\sim}71%$. Health and welfare mixed type facilities were preferred, and the most important consideration was the level of professionalism. Conclusions : Intention to actual use of the charged services was largely determined by the aspects of time and cost. Polices to increase the number of service suppliers and to decrease the burdens perceived by actual supporters were strongly recommended.

The purpose of this study was to investigate determinants of stop smoking. The data on which the analysis was based come from a survey of 355 middle-aged men in Seoul. The data was analyzed using proportion, x²-test, Pearson's Correlation Coefficient and Stepwise Multiple Regression. The following were the results; 1. Success rate of stop smoking is 19.9% of 229 persons who attempted to quit smoking. 2. As for the number of quit attempts, 33.3% of ex-smokers tried once; 25.4% of current smokers tried twice. 3. As for methods of quit attempts ex-smokers showed higher tendency in using will power and books/guides than current smokers who in using will power alone. 4. For the attitudes on smoking of family, the majority of ex-smokers and current smokers were opposed absolutely. 5. The main opposite to smoking were wives in cases of both ex-smokers and current smokers, but More ex-smokers answered that the main opposite to smoking were others than current smokers. 6. As for the measures of smoking in the office, more ex-smokers answered inviting than current smokers and more current smokers assigned a smoking spot than ex-smokers. 7. Majority of ex-smokers approve of restriction at public spot strongly. 8. As for the attitude about caution on a cigarette case, more ex-smokers insisted than current smokers. 9. There was a relation between the degree of exposure about knowledge and the degree of knowledge. 10. Stepwise Multiple Regression portray that following factors influence stop smoking in order named. (1) attitude on the smoking restriction at public spot, (2) methods of quit attempt, (3) attitude about caution on cigarette case. Even so, it turned out that these factors alone can explain only 20% of self-examination. Therefore study for the other factors ought to be continued. I submit following suggestions ending this study. 1. Continuous study of the other factors affecting stop smoking must be carried on. 2. Since there was a relation the degree of exposure about knowledge and the degree of knowledge, efficient health education is required using campaign and mass media.
