The purpose of this study was to analyze the effects of smart machine circulation exercise on body composition, lung function, blood lipid and insulin resistance in obesity middle-aged women among 40-60 years by dividing them into a smart machine circulation exercise group(n=8), and control group(n=6). The smart machine circulation exercise program included 55-minutes sessions thrice each week at the following intensities: The strength of aerobic exercise is applied to smart machines by linking the smart machine with the POLAR T31; the 1-4 week is 40-50%HRR, 5-8 week is 50-60%HRR, and 9-10 week is 60-70%HRR. The strength of the resistance exercise was tested using a smart machine based on the constant velocity motion, and then, using the 1-RM data value, applied 40% 1-RM for 1-4 weeks, 60% 1-RM for 5-8 weeks, and 80% 1-RM for 9-10 week. As a results, body composition indicated that weight, BMI, %BF, WHR had a significant interaction effect. Lung function indicated that FVC levels significantly changes in the exercise group and the between groups difference in changes at 10week was significant. Also, FVC and FEV₁ significantly showed interaction effect. TC, TG and HDL-C levels significantly changes in smart machine circulation exercise group and the between-group difference in changes after 10 weeks was significant. TC, TG and HDL-C significantly showed interaction effect. Insulin resistance demonstrated that Insulin, Glucose and HOMA-IR levels significantly showed difference over 10 weeks between group. Therefore, the 10 weeks smart machine circulation exercise positively effects on the body composition, lung function, blood lipids, and insulin resistance in obesity middle-aged women and this smart machine circulation exercise can improve their obesity and prevent obesity.

One hundred twenty healthy college students and housewives from urban middle income household were investigated in terms of food consumption patterns, nutrient intake and dietary fiber intake. Total food intake was slightly lower in college students(1059.9g/d) than in housewives(1160.g/d) . However, the ration of animal food to total food was considerably higher in college students(23.7%) than in housewives(16.8%). College students tended to consume more dairly products, meat & products, and cereals & grain products but less vegetables , fruits, fish and shellfish than housewives. Although nutrient intake was not much different (except for total calories, fats, and ascorbic acid), dietary fiber intake was slightly and significantly lower in college students(14.9g/d, 8.3g/1000kcal) than in housewives(16.9g/d, 103g/1000kcal) . That is partially due to college students irregular food habits and the change in their meal patterns from traditional to western diets. There was a significantly positive correlation between dietary fiber intake and thiamin, riboflavin, niacin and crude fiber intake.

The purpose of this study was to determine the health behaviors and nutritional status related to dyslipidemia in Korean middle-aged adults (between 50 and 64 years old) from the Korean National Health and Nutrition Examinations Survey data (2007~2010). A total of 4,721 subjects were analyzed in this study. The subjects were divided into three groups (normal, borderline, and dyslipidemia) according to serum lipid levels. Parameters included in this study were drinking and smoking, anthropometric parameters, blood and nutritional parameters. The latter parameter included food/nutrients intake. All data was adjusted by sex, region, education level, and age. General linear model and logistic regression model were used for statistical analysis. The dyslipidemia group was comprised of more men than women. By contrast, the borderline group was comprised of more women than men (p<0.001). No significant differences were observed for other general characteristics. There were more smokers and drinkers(drinking per time) in the dyslipidemia group (p<0.05). Anthropometric data showed significant difference, ie, height (p<0.05), weight, body mass index, waist circumference, percent body fat, and blood pressure were higher in the dyslipidemia group (p<0.001). Only blood urea nitrogen showed no significant difference among groups. The HbA1c (p<0.01), fasting blood glucose, GOT, GPT, creatinine levels were higher in the dyslipidemia group (p<0.001). So it is required for the management of obesity in dyslipidemia group. The dyslipidemia group ate less sea food (p<0.05). The nutrients intake of energy and protein, thiamin, riboflavin, niacin, calcium, phosphorus were lower in the dyslipidemia group (p<0.05). Therefore, to lower dyslipidemia prevalence rates, it is necessary to increase the intake of foods containing ${\omega}-3$ fatty acids. We also suggest a meal management program and nutritional education to recognize the risk of dyslipidemia, especially for people such as the individual in the borderline and dyslipidemia study groups.

The principal objective of this study was to provide basic data regarding health care services for middle-aged men, via an analysis of the relationships among stress level, food habits and well-being-related attitudes with social-demographic characteristics and health-related factors. The main findings of this study were as follows. The average age of the participants was $48.7{\pm}5.2$. With regard to health status, 18.8% of the participants were diagnosed with digestive diseases within the past year. Stress levels were higher in the participants with lower levels of educational attainment. Furthermore, participants who had become divorced or lived separately from their families, participants who did not have their own houses, and participants who reported low marital satisfaction also had high levels of stress. Our food habits scores revealed meaningful differences among the study subjects, and were shown to vary with marital satisfaction, occupation, and residence type. In terms of both the importance and practice level of well-being-associated food habits, the most frequent response in this study was 'Consume home-made food rather than processed or ready-to-eat food' ($4.30{\pm}0.86$, $3.68{\pm}1.04$). In terms of importance level, the factors most relevant to well-being in terms of food habits were education level, marital satisfaction, residence type, self-assessed health status, smoking, drinking, regular exercises and leisure activities. With regard to practice levels, the degree to which subjects engaged in food habits targeted toward well-being differed meaningfully depending on marital status, marital satisfaction, residence type, family type, self-assessed health status, smoking, drinking, nutritional supplement intake, regular exercises and leisure activities. After analyzing the correlation among stress level, food habit score and the attitude towards well-being-related dietary habits (importance and practice level), we observed a meaningful relationship between the four factors at the level of p<0.001. According to the above result, continuous attention to health, including the appropriate control of smoking and drinking, as well as, stress management, via regular exercises and appropriate food habits is expected to exert a positive influence on the prevention of disease, and is also expected to improve quality of life. For all well-being-associated items, the importance level was shown to be higher than the practice level. Thus, in order to foster health-oriented food habits, we recommend that a new plan be designed, targeted toward ease of active practice for middle-aged men.

This study was conducted to compare the validity of obese index among body mass index(BMI), waist to hip ratio(WHR), and waist circumference(WC) and to determine which is the best in relation to cardiovascular risk factors of middle aged Korean(40-64yr).Data from the 1998 Korean Health and Nutrition Survey were used(N=3380). Anthropometric indices and cardiovascular risk factors were measured. Chi-square test, analysis of variance following duncan's multiple range test, partial correlation analysis, and Receiver Operator characteristic(ROC) curves were used in the analysis. There was a significant increasing trend in WHR, systolic blood pressure(SBP), high density lipoprotein cholesterol(HDL), and fasting blood sugar(FBS) with age categories of male and in BMI, WC, WHR, diastolic blood pressure(DBP), SBP, total cholesterol(TC), low density lipoprotein cholesterol(LDL), triglycerol(TG), and FBS with those of female. Specially female had the characteristics of upper body fat and systolic blood pressure risk(p<0.05). Proportions of subjects with lifestyle factors related to cardiovascular risk in overweight or upper body fat group were higher than that of normal group. Higher proportions of subjects were practiced exercise in upper body fat group of male than in other groups. Among 7 cardiovascular risk factors in partial correlation analysis, BMI had the highest correlation coefficient in 6 risk factors in male, whereas WC in 4 risk factors in female. Mean of each obese index according to cardiovascular risk groups except smoker was higher than that of normal(p<0.05). These trends were shown in upper body fat group and female. In ROC analysis of 12 risk factors and health conditions, the largest area under curve among obese indices for risk factors were BMI in male and WHR in female. The optimal cutoff values of each index(BMI: WHR: WC) for one or more cardiovascular risk factors were 23.13: 0.89: 85.35 in male and 23.57: 0.84: 78.35 in female. The results showed that cardiovascular risk factors were prevalent in middle aged Koreans within normal limits of obese indices like another Asians. For the identification of cardiovascular risk factors of middle aged Koreans, BMI for men and WHR for women are appropriate indices. But it is recommended that BMI, WHR, and WC, all three indices should be considered, when using these indices.

The purpose of this study was to investigate the relationship between resilience, social support and caring burden of middle-aged caregivers caring for chronic disease. The data were collected from 175 caregivers at one rehabilitation centers in B City from July 2 to 31, 2018 and analyzed SPSS Win 21.0. Factors influencing caring burden were time for caregiving(F=6.70, p<.001), activities of daily living(F=4.70, p<.001), patient disease(F=4.61, p<.001), relationship with patients(F=3.68, p<.013), Health Status(F=3.08, p=.018), Marital status(t=-2.12, p<.036), Period after diagnosis(F=2.92, p=.036). The caring burden had not an influence on resilience and social support. a positive correlation was found between resilience and socail support(r=.487, p<.001). Therefore, it is essential to develop burden intervention programs that can reduce the burden in middle-aged caregivers caring for chronic disease and taking all the factors affecting burden into consideration.

This study attempted to explain how middle-aged married men and women prospected their family life in terms of their future coresident family members, caregivers, and residence, and what factors were associated with these prospects. The prospects reflected their realistic expectation rather than their preference based on their current life situations. Data were drawn from a survey of 800 married men and women in their 50s and 60s in Seoul and Gyunggi-do. Following previous research, we examined how resources (age, sex, health status, spouse's health status, number of children, current living arrangement, and household income), subjective perception on their responsibility for their parents and children, and relational satisfaction with their spouse and with their children were associated with the prospect. The results showed that these factors were associated with the prospect which is with whom they would live, who would care for them, and where they would live in different ways. The resources were more likely to be associated with the prospect on coresident family members and residence. The perceptions on responsibility were more likely to be associated with the prospect on caregivers. The relational satisfaction was more likely to be associated with the prospect on coresident members. These results underscored that the characteristics of caregiving and family life would change in 10-20 years. Family policymakers need to take these changes into consideration as they deal with issues of family policy.

The purpose of this study was to develop the pattern drafting method which would be suitable to their physical characteristics for the fatty body of 40∼55 aged Korean women who are more than 1.5 Rohrer's Index and 90㎝ bust girth. The study was composed as follows; 1. Body measurement and statistical analysis: One hundred and thirty women were measured on 29 items. Thirty-four items including 29 measured items and 5 calcutated items were analyzed statistically. 1) Mean, standard deviation, variance, maximum, minimum, range were computed. 2) Correlation coefficients between each items were computed. 2. Development of new bodice pattern drafting method: Measurement items necessary to draft new bodice pattern were bust girth, center back waist length, shoulder width, back width, chest and neck base girth. The new pattern was examined through three wearing tests for completion. 3. Evaluation of the new pattern drafting method: The new pattern was objectively evaluated by the sensory test. The sensory evaluation was applied to evaluate the new pattern for the fatty body women by comparint it with the conventional patterns. The results of sensory tests of the new pattern are as follows: 1) The composite reliability coefficient is 0.7698, and the reliability of sensory test shows high. 2) According to a statistical analysis of the result of the 23 items on the questionaire, all the items showed significant differences(α 0.01) between the two, with the new pattern having higher scores. The new pattern is better conventional pattern as the average mark of the former is 3.901 but that of latter is 2.926. The new pattern drafting method proved to be superior to the conventional one especially in the fitness at the center front neck point, shoulder point, side line, armscye depth, position of bust point, chest width line, under arm dart and the shoulder line.

Purpose: This study aims to identify differences in breast self-examination (BSE) performance and influencing factors between woman-groups under and over 45 years old. Methods: The subjects were 152 women aged from 35 to 65, who were recruited through convenient sampling in a metropolitan city. They were divided into two groups: under and over 45 years old. The data were collected using self-reporting questionnaires and analyzed by $x^2$ test, t-test, Pearson's correlation coefficient, and stepwise multiple regression. Results: Experience of BSE education ($x^2$=4.68, p=.030), BSE performance ($x^2$=20.12, p<.001), confidence (t=-2.97, p=.003), and self-efficacy (t=-2.44, p=.016) were significantly higher in the group over 45 years (the older group) than the one under 45 years (the younger group). Self-efficacy (${\beta}$=.346, p=.004) and susceptibility (${\beta}$=.238, p=.002) were 17.6% of the variance in the younger group's BSE performance. On the other hand, significantly influencing factors on the older group's BSE performance were self-efficacy (${\beta}$=.500, p<.001) and BSE education (${\beta}$=.217, p<.001), which accounted for 25% of the variance in the BSE performance. Conclusion: We conclude that differentiated strategies of considering age should be established in nursing intervention to detect breast cancer early.

We investigated whether socioeconomic differences affect fruit and vegetable (FV) consumption with respect to total intake and intake of various FV subgroups. Our study included 6667 adults aged 40-64 years who completed a dietary survey in the fourth Korean NHANES (2007-2009). FV intake was estimated from 24-hour recalls and food frequency questionnaires. Differences in FV consumption related to educational attainment were analyzed according to different nutritional categories of FV. Both men and women in the low-education group had the lowest intake of total FV and total fruits, and women also had the lowest intake of total vegetables. Also lowest in this group was consumption of mushrooms and vegetables (excluding kimchi) among men, and cruciferous and allium vegetables (excluding Chinese cabbage and radish) among women, while kimchi consumption was the highest in this group. Additionally, an association between educational level and intake of citrus fruits was evident among men. Adults in the low-education group consumed less carotene-rich FV, red fruit and/or vegetables, and dark-green leafy vegetables, fewer total vegetable dishes, and fewer types of fruit than in other groups. Men in this group had the lowest intake of yellow/orange fruit and/or vegetables, and women consumed the least folate-rich FV. There is a clear association between educational attainment and FV intake with regard to total intake, and to specific nutrients, bioactive compounds, colors, and variety.
