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.

The purpose of this study was to search and analyze the realities and needs of life long education, the necessity and perception of life competencies and the difference of competencies on experiences of education to support life long education system for adult learners in Busan and Ulsan. In this study, we conducted a questionnaire survey of 234 adult learners living in Busan and Ulsan. The results of this study were summarized as follows. First, adult learners perceived that life long education was very important to adults and appreciated an educational institution being managed by government. Second, adult learners thought that basic literacy competency and basic work competency were important and late fifties perceived that professional job is in important. Third, adult learners perceived that self directed learning and capacity of management are poor competencies. And they perceived that the government support adult learners who has economical difficulty. Forth, adult learners perceived that it was normal that 'professional job' and 'job transition abilities', 'women', 'the middle aged and old','the unemployed' and' low incomers' perceived that they have poor level. Fifth, according to the results of ${\chi}^2$ test for determining the statistical significance of differences in experience in lifelong learning among adult learner groups divided by their individual background, significant differences were observed in a few competencies(p<.05, p<.01).
This study identifies how people use bicycle wear, complaints about bicycle wear, and functions required for bicycle riding. This survey was conducted with bicycle club members (men and women) in their twenties to sixties who ride bicycles on a regular basis. A total of 373 subjects responded to questionnaires and 326 responses were used for further data analysis. The data was analyzed by descriptive analysis, multiple response analysis, crosstabulation analysis, factor analysis, reliability analysis, and one-way ANOVA. The results are as follow: First, the people surveyed were primarily men, young adults and middle-aged people. They ride bicycles mainly to participate in club activities, to exercise, and to spend their spare time with a well-being trend that focuses on leisure and health. Second, they often utilize bicycle wear when they ride bicycles. They are aware of bicycle wear brands. In addition, a majority have purchased bicycle wear that shows a very high awareness of bicycle wear. Third, as for complaints about bicycle wear worn when riding bicycles, a majority of people answered that the waist part of the top pulls up and they feel sore with the bottom part of the pants when riding bicycles for a long time. They also answered that it is inconvenient to put belongings in both tops and pants. Fourth, there is a high demand for safety-related functions for bicycle riding in regards to the functions required for bicycle wear. In addition, a majority of the members showed a customer awareness of functional bicycle wear and intended to purchase bicycle wear equipped with smart functions.
This study analyzes important urban characteristics according to location of large-scaled professional sports facilities based on a binary logistic regression model and t-test. For the empirical analysis, this study uses 24 urban characteristics within social, economic, cultural, traffic, and spatial categories in 228 cities. The results show that economic condition can be the main decision factor for the differential feature of the location as well as social and traffic conditions. Concretely, more the number of young adults and middle-aged people who have considerable purchasing power, and available land are more the beneficial to the presence of the sports facilities. Recently local governments focus on location of the facilities due to their impacts on regional economics as well as residents' quality of life. In this point of vies, this study gives good understanding why it is a great option for location of the facilities.
The purpose of this study was to compare the anthropometry, the serum lipid levels and the nutrient intakes of two groups according to their alcohol intake, smoking habits, regular exercise patterns, menopause status and obesity levels. The subjects consisted of 180 clinically normal adults (males 89, females 91) in the Youngdong area. There were significant differences in the triglyceride (TG) concentrations between the alcohol consumers (169.3 \pm 130.0 mg/dl) and the non-alcohol consumers (111.4 \pm 64.5 mg/dl), and the smokers (165.0 \pm 103.6 mg/dl) and the non-smokers (110.8 \pm 39.0 mg/dl). Although regular exercise did not affect the serum lipid levels, the dietary intakes of cholesterol, niacin and phosphate were significantly higher (p<0.05) in the male exercising group than in the male non-exercising group, and female exercising group consumed more polyunsaturated fatty acids (p<0.05) than the female non-exercising group. The waist/hip ratio. serum total cholesterol (198.4 \pm 36.3 mg/dl) and serum LDL-cholesterol (119.5 \pm 34.9 mg/dl) levels of the postmenopausal females were significantly higher than those of the premenopausal females (p<0.01). The obese males showed higher serum cholesterol, LDL-cholesterol, LDL/HDL, and relative cholesterol levels than those of the normal-weight males : and the obese females showed higher serum TG levels than that of the normal-weight females (p<0.01). These results suggested that drinking, smoking, menopause and obesity are risk factors for hyperlipidemia. Thus, moderation in alcohol consumption, non-smoking, regular exercise and the maintenance of normal weight are necessary to Prevent hyperlipidemia in middle-aged People.
To establish a basic cohort which can survey the nutrient and food intake related to the health status of the middle and old-aged vertically, a longitudinal survey of 110 adults over forty years old was conducted three times in Chon-ju city over 5 years (1994-1999), and the influences of health status by changes in their nutrient and food intake were examined in this study. The results were as follows ; The number of subjects was 110(43 man, 67 women), 10.0% in their forties, 28.2% in their fifties, 45.4% in their sixties 6.4% over seventy, and their average age was 61.4. There were decrease of height about 1cm , increase of body fat % and few changes of BMI during the testing period. As the subjects were aging, the percentage of anemia increased, but averages of blood pressure and blood glucose(men : 91.8mg/㎗, women : 90.3mg/㎗) were constant. Total cholesterol increased from 196.7mg/㎗ to 212.6mg/㎗(P 0.05) over five years, and the numerical values for women were higher than that of men. In many cases, lack of nutrient intake was shown, as compared with the Recommended Dietary allowance(RDA) especially calcium and vitamin A(71.7%, 64.9% of RDA). Grains intake showed a tendency to decrease(P 0.01). On the contrary, fruit intake showed a tendency to increase(P 0.001). On whole meal, plant foods were 85.1% and animal foods were 14.9%. As dietary factors influencing health status were investigated, blood glucose was influenced by vitamin B$_2$, potatoes and triglyceride, DBP and SBP were affected by vitamin B$_1$, vitamin C, legumes, fishes, triglyceride and age. Total cholesterol was under the influence of triglyceride, milk, seeds and fat. BMI was influenced by iron, SBP, animal food, and age.
This study was performed to determine the effect of carotenoid-rich food consumption and smoking on the lipid peroxidation and antioxidant status in human. The subjects consisted of the health 210 middle-aged adults who visited health care center in the Inha University hospital. The blood and urine samples of the subjects were taken to analyze serum lipid profiles, plasma TBARS, total antioxidant status (TAS) and urinary 8-isoprostanes concentration. The anthropometric indices of the subjects were measured. The nutritional intake and the frequency of carotenoid-rich food consumption was determined by semi-quantitative food frequency questionnaire survey. HDL-cholesterol level of the smoking subjects was significantly lower than that of the non-smoking subjects in men. In the analysis of the carotenoid-rich food consumption, the frequency of pepper and tomato consumption of the non-smoking subjects was significantly higher than that of the smoking subjects in men. In women, the Sequency of pear and peach consumption of the non-smoking subjects was significantly higher than that of the smoking subjects. HDL-cholesterol level of the high carotenoid rich food consumption group was significantly higher than that of medium and low group in women. TAS of the high carotenoid rich food consumption group was significantly higher than that of medium and low group. In conclusion, carotenoid intakes seemed to be effective to reduce lipid peroxidation and increase antioxidant status in the body. The frequency of the carotenoid-rich food consumption seemed to be lower in the smokers than in the non-smokers. However, further researches consisted of large-scaled and randomized clinical trials are required to determine whether carotenoids have any other beneficial effect in human.

Objectives: This study aims to develop a decent sallimyok program and provide basic data which are helpful in improving psychological wellbeing for adults who are exposed to stress and fatigue. Methods: Middle-aged women living in Cheongju, Chungbuk were divided into experimental and control groups (10 people each) through convenience sampling, and a questionnaire survey on psychological wellbeing was distributed to them and collected. For data analysis, IBM/SPSS 20.0 was used. In terms of statistical analysis, a reliability test (Cronbach's ${\alpha}$) was conducted. To test research questions 1 and 2, independent t-test and paired sample t-test were carried out. Results: First, a sallimyok program features meditation (floor-sitting, slow walk), forest therapy, stretching exercise, wrapping-up and sharing feelings. Second, it was confirmed that a sallimyok program has a positive effect on the improvement of psychological wellbeing and the depression for women. Conclusions: The sallimyok program improved participants' psychological wellbeing, which means that it could reduce their anxiety and stress.
This study investigated the effects of self-esteem on the depression of baby boomer and eco-boomer generation (the children of baby boomers) living alone. It was identified from the point of view of comparison between the two groups. Using the 15th data of the 2020 Korea Welfare Panel, an independent sample t-test and hierarchical regression analysis were conducted with the data of baby boomers who live alone (born in 1955-1963) and eco-boomers who live alone (born in 1979-1992). The results of this study show that baby boomers who live alone had lower levels of education, income, and health condition than the eco-boomers who live alone, and had higher level of depression, but relatively lower level of self-esteem. In both groups, self-esteem had an effect on depression, but it was confirmed that the influence was greater in the group of baby boomers (Adjusted R2 .259) than in eco-boomers (Adjusted R2 .083). Based on the results of this study, practical and policy alternatives were suggested to prevent the depression among middle-aged, elderly people, and young adults who live alone.
Objectives: The objective of this study was to perform a scoping review to describe clinical study trends on Qigong in order to identify further directions of Qigong in Korean medicine. Methods: Under the Arksey and O'Malley methodological framework, PubMed was searched to identify articles published from January 1, 2019 to June 28, 2021. A total of 224 articles were retrieved. Results were systematically filtered by two independent reviewers based on inclusion/exclusion criteria. Publication information, disease, intervention and research results of a total of 153 articles were extracted and analyzed. Results: Asia had the largest number of Qigong studies (82 studies, 65%). Most research studies were conducted in the academic field of Medicine (n=109, 86.5%), including Complementary and Alternative Medicine (n=35), Medicine (miscellaneous) (n=15), and Oncology (n=15). Based on ICD-10 classification, Mental and Behavioral Disorder (n=25, 19.8%) was the most frequently analyzed decease, followed by Neoplasm (n=24) and Disease of the Nervous system (n=12). Almost half of all studies were Systematic Reviews. RCTs only accounted for 25.4%. Interventions were very diverse and inconsistent. Sixty (47.6%) studies analyzed Qigong as a single intervention. In 66 cases, Qigong was analyzed as part of a large category such as Mind-Body intervention. Most studies designed a Donggong (動功) program. The age of the population was relatively high as 47.1% of all studies were conducted on middle aged or older adults. Conclusions: These findings suggest that further standardized research on Qigong, especially Junggong (靜功), needs to be conducted by developing research protocols and practice programs to verify effects of Qigong and utilize Qigong as a medical intervention in Korean Medicine.
