The purpose of this study is to examine the factors affecting on CRPI (capability of retirement planning and implementing) and to identify the critical point of financial factors to increase CRPI. 908 Korean individuals' data were used for descriptive statistics, t-test, F-test, and Generalized Linear Mixed Model Analysis. As a result, CRPI was influenced by attitude toward retirement planning, gender, income, and propensity to save. Some mid-group did not make a significant difference in CRPI compared to the lower-group. Men were more capable at CRPI than women in terms of sense of independence and getting a consulting service. Most consumers appear to have difficulty in calculating their retirement fund. People who have income over 3,000,000 won have dramatically greater CRPI than people who have income under 3,000,000 won. And people who have saving ratio over 23% have significantly greater CRPI than people who have propensity to save under 23%. The monthly income 3,000,000 won and propensity to save 23% were considered as critical points related to CRPI.

This study was conducted to investigate the effect of different fattening periods on the growth performance, carcass characteristics, and economic traits of Holstein steers. Sixty Holstein steers (8.0 ± 0.28 months old) with an average body weight (BW) of 231.88 ± 2.61 kg, were randomly allocated to five different fattening period treatments: 20, 21, 22, 23, and 24 months (n = 12 in each treatment group). Final BW and average daily gain (ADG) did not differ among the treatment groups during the early fattening period. At the late stage of the fattening period, the final BW of steers in the 24-month treatment group (812.84 kg) was greater (p < 0.05) than that of steers in the 20-month treatment group (750.39 kg). During the same period, steers in the 20- and 21-month treatment groups had a significantly higher (p < 0.05) ADG than those in the 22-month treatment group. The highest ADG (1.36 kg/day) was found in the 20-month treatment group (1.36), followed by the 21- (1.33 kg/day), 22- (1.22 kg/day), 23- (1.21 kg/day), and 24- (1.14 kg/day) month treatment groups. The feed conversion ratio (FCR) increased as the fattening period increased, and the FCR was 12.88% lower in the 20-month treatment group than in the 24-month treatment group. However, no significant differences were detected in back-fat thickness, loin area, marbling score, and chemical characteristics (water, crude protein, and crude fat content) among the treatment groups. The composition of fatty acids including C18:0, C18:1, saturated fatty acids, unsaturated fatty acids, and poly-unsaturated fatty acids did not differ among the experimental groups. As the fattening period increased, production costs increased, resulting in a decrease in gross income. The gross income for steers in the 24-month treatment group was 35.8% and 23.5% lower than that for steers in the 20- and 21-month treatment groups, respectively. Taken together, the best performance, including the ADG, FCR, and gross income, was obtained when the fattening program of the Holstein steers lasted 20 months.

This study attempted to classify the residents of rural area into some groups according to the level of their community satisfaction by decision tree model. The variable that has the greatest influence on grouping rural residents according to community satisfaction is income. However, it appears that the variable of participating in the community activities can weaken their influences. The second most satisfying group is the group of people who are lower-income and active in community activities. On the other hand, the group of people who are high-income and inactive in community activities are included to unsatisfying groups. These findings suggest that community participation can be a major factor in enhancing the quality of life of residents in the rural communities. What is noteworthy is that marital status is used as a major variable to classify the rural residents into some groups according to the level of community satisfaction. This suggests that the issue of marriage is still a major problem in rural communities.

As a society is becoming more and more complicated people living in modern times are experiencing more stresses for various reasons. Some past research results proved the role of clothing in reducing the stresses. The purpose of this study is to investigate how the preference of the mini-style which is recently most fashionable styles is related to the psychological factors such as stress and body satisfaction. Measure Instrument were Nolmes and Masuda(1973)'s SRRS(Social Readjustment Rating Scal) Secord and Jourard(1953)' Body Cathexis Scale and mini-style preference scale by author Survey questionnaires were distributed to two hundred seventy adult women living in Seoul area during may 25 1992. through June 8. 1992. The age range of the subjects was from 30 to 49 The final number of subjects in-cluded in the statistical analysis was 244. The result and conclusions are as follows: 1. Significant difference was existed in mini-style preference between high and low body satisfaction groups. Mini-style was pre-ferred by high body satisfaction group than low body satisfaction group. 2, Significant difference was existed in mini-style preference between high and low stress groups. Mini-style was preferred by low stress group than high stress group. 3. Regarding demographic characteristics unmarried 2 year college graduates with low family income in their early 30's pref. mini-style. 4. There was a marginal interaction effect of demographic characteristics on the relation-ship between mini-style preference and body satisfaction. The higher preference and body satisfaction. The higher preference for mini-style was found for the higher body satis-faction group mostly with the age range of 35 to 39 married 4 year college graduates as drop-puts and mid less income group. 5. There was a marginal interaction effect of demographic variables on the relatonship be-tween mini style preference and stress level The higher preference for mini-style was re-lated to the low stress level group mostly with age group of 35 to 44 high school graduates or lower and highest income group regardless of their marital status. In sum mini-style seems to be preferred by women who feel relatively less stress and are more satisfied with their bodies thus psycho-logically stable.

Purpose: The purpose of this research was to compare the effects of Danjeon Breathing exercise and walking exercise on blood lipids, physical symptoms and hemoglobin of middle-aged women to determine which of these two exercises was more beneficial. Methods: The Danjeon breathing exercise group(20) took health management counseling and performed an eighty-minute Danjeon breathing exercise three times a week for 12 weeks while the walking exercise group(25) took health management counseling and performed a walking exercise seven hours per week for 12 weeks. The control group(20) received only health management counseling. The groups were homogeneous on age, religion, marital status, education, profession, monthly income per household, menopause, smoking, drinking, fat intake and cholesterol intake. Likewise, the groups were homogeneous on total cholesterol, HDL-cholesterol,atherogenic index, hemoglobin and physical symptoms. The collected data were analyzed by using the SPSS PC program and $x^2$-test, ANOVA, repeated measures of ANOVA and LSD. Results: 1. Total cholesterol of the Danjeon breathing exercise group and the walking exercise group were lower than that of the control group. 2. HDL- cholesterol of the Danjeon breathing exercise group and the walking exercise group were not higher than that of the control group. 3. Atherogenic index of the Danjeon breathing exercise group was lower than that of the control group, but atherogenic index of the walking exercise group was not lower than that of the control group. 4. Hemoglobin of the Danjeon breathing exercise group and the walking exercise group were not higher than that of the control group. 5. Physical symptom score of the Danjeon breathing exercise group was lower than those of the walking exercise group and the control group, but Physical symptom score of the walking exercise group was not lower than that of the control group. Conclusion: Danjeon breathing exercise and walking exercise are effective for decreasing total cholesterol of middle-aged women. Danjeon breathing exercise is more effective for decreasing atherogenic index and physical symptoms of middle-aged women than walking exercise.

The purpose of this study is to investigate the effects of participation in cultural activities on happiness. The empirical results show that participation in cultural activities has a positive impact on individual happiness, because cultural activities cause entertainment and social contacts with people. Furthermore, the levels of income and education are analyzed by dividing them into high and low groups. Noteworthy is that the low-income and less-educated groups show lower participation in cultural activities than those in the high-income and well-educated groups, But the utility magnitude gained through cultural activities is higher. This implies that opportunity costs arising from financial and time constraints are greater in the low-income and less-educated groups than in the high-income and well-educated groups. Finally, for the low-income group, the marginal utility is reduced when spending on cultural activities exceeds certain levels, which means there exist a budget constraint for the low-income group.

The purpose of this study was to examine the health care expenditure of elderly single and elderly couple households whose head is more than 60 years old. The data analyzed for the study were Korean Retirement and Income Study(KRelS) conducted in 2007 by National Pension Corporation. The major finding of this study were as follows: First, the amount of health care expenditure of elderly single households was lower than that of elderly couple households. However, ratio of health care expenditure to total consumption expenditure of elderly single households was larger than that of elderly couple households. Second, the ratio of health care expenditure in consumption expenditure in this study was larger than the ratios in past analyse showed in the previous studies. Third, common factor affecting on health care expenditure of elderly single and elderly couple households was the existence of the family member with chronic disease or handicap. The health care expenditure of elderly singer households was influenced by income, gender and the ownership of national health insurance. The influence of income for elderly singer households seemed to be greater than for elderly couple households. The variables which affected health care expenditure of elderly couple households were age and housing tenure status. The amount and ratio health care expenditure were increased as the age increases. These results show that the health care expenditures for each groups varied according to socio-demographic variables and health-related behavior variables. It is suggested that there should be a discriminative health care policy for each elderly single and elderly couple households. In addition, the health care policy for the elderly households of which member has a chronic disease is certainly necessary. Especially a health care plan for the elderly single households with lower income is in need. For the elderly couple households, the priority group of health care policy would be the high age group.

This study was performed to evaluate the quality of nutrient intakes of the hemodialysis patients (26 men and 23 women) according to the socioeconomic status by 3-day dietary recall in Daejeon city and Chungnam area, Korea. Mean age of the subjects was 50.7 yrs and BMI was 22.0 $\pm$ 0.4 kg/$m^2$. Education level was divided into two groups ($\leq$ 9 years： LE group, 9 years： HE group), and monthly family income level was divided into three groups (< 500,000 won: LI group, 500,000-1,499,999 won: MI group, $\geq$ 1,500,000 won : HI group). The data were analyzed by Student t-test and Oneway ANOVA using SPSS 9.0 version at p < 0.05 level. Intakes of energy, carbohydrates, cholesterol, potassium, thiamin and riboflavin were significantly higher in HE group than in LE group (p < 0.05). Intakes of all the nutrients except protein and phosphorus were less than Korean RDA, and INQs (Index of Nutritional Quality) of most nutrients were lower than 1.0 but cholesterol, phosphorus. thiamin and niacin being over 1.0 in HE group. MAR (Mean adequacy ratio) of all the nutrients (e.g., energy, protein, calcium, phosphorus, iron, vitamin A, vitamin C, thiamin, riboflavin and niacin) was significantly higher in HE group (0.61 $\pm$ 0.04) than in LE group (0.48 $\pm$ 0.03) at p = 0.036. Intakes of energy, protein (total, animal and plant), fat, cholesterol, potassium, calcium, phosphorus, iron, vitamin A, thiamin and riboflavin were also significantly higher in HI group than in LI and MI group (p < 0.05). Daily intakes of most nutrients were less than Korean RDA except protein ed phosphorus in HI poop, and INQs of thiamin, niacin and phosphorus were higher than 1.0, while those of calcium, iron, vitamin A and riboflavin were lower than 1.0. MAR of energy and 9 nutrients was significantly higher in HI group (0.70 $\pm$ 0.04) than in LI group (0. 56 0.04) and MI poop (0.47 $\pm$ 0.03) at p = 0.000. In conclusion, quality of nutrient intakes, especially energy and protein, was significantly influenced by socioeconomic status such as education and monthly income (p < 0.05). This result suggests that it would be very helpful to develop nutritional education programs considering hemodialysis patients' education levels, and to improve public supports (e.g., medical insurance system, low-rate lease system of dialysis equipments, etc.) focusing on the patients' family income levels f3r their better nutrition and health.

This study investigated the influence of obesity on depression and stress by analyzing the results of the national survey on health and nutrition. Relationships between normal, obese, and severely obese groups were investigated. The results of the study are as follows. First, obesity caused by demographic variables showed a relationship to both gender and average monthly income. In the case of the seriously obese group, females had higher rates of depression than males, and the high obesity group had lower average monthly income than the normal and obese groups. Second, obesity caused by health-related variables found that high blood pressure, hyperlipidemia, and diabetes that was not angina-related displayed higher rates of depression in the serious obesity group than in the other groups. As for subjective evaluations of one's own health condition, the serious obesity group showed a high tendency to evaluate their own health conditions negatively. Third, the difference between depression and stress related to obesity level showed no difference between the normal weight group and the obesity group; however, the seriously obese group demonstrated relatively higher occurrences of depression and higher stress scores. Fourth, the result for depression and stress level caused by demographic variables, health-related variables, and obesity demonstrated a direct relationship to gender, subjective level of satisfaction with one's personal finances, average monthly income, subjective perception of one's own health and severely obesity status. More specifically, it was found that the ratio of depression and stress score was higher when the subject was female, among those whose subjective evaluation of their own finances and health condition was negative, and those who suffered from severe obesity.
