Purpose: To investigate factors related to cardio-cerebrovascular disease and groups disadvantaged by it in Korean middle-aged women, using the Korea National Health and Nutrition Examination Survey (KNHANES). Methods: The present study was conducted with 1,627 middle-aged women, aged 40 to 64 years, who participated in the 7th (2016) Korea National Health and Nutrition Examination Survey conducted by the Korea Centers for Disease Control and Prevention. Results: Cardio-cerebrovascular disease among middle-aged women was associated with quality of life, menopause, diabetes mellitus, body mass index, and family history of hypertension. The incidence of cardio-cerebrovascular disease in middle-aged women was found to be the most prevalent in women who have entered menopause, have a family history of hypertension, and have a body mass index greater than $30.0kg/m^2$. Conclusion: This study classifies the subjects according to the risk level of each disadvantaged group for cardio-cerebrovascular disease prevention and management in middle-aged women. The results provide evidence to support a tailored cardio-cerebrovascular disease prevention and management program based on the related factors of disadvantaged groups and to establish strategies in educational and practical aspects.

Purpose: The purpose of this study was to explore the self management and related factors that affect the self management of diabetes between the middle aged and elderly groups. Method: This study was based by the conceptual framework of Cox's interaction model of client health behavior. The subjects were two groups; the middle aged group, 80 and the elderly group, 85 who were diabetes mellitus patients. Result: In the middle aged group, gender, education and social support were significantly correlated with self-management of diabetes mellitus. In the elderly group, gender, education, social support and the duration of diagnosis were significantly correlated with self-management of diabetes mellitus. In too middle aged group, the intrinsic motivation of diabetes mellitus patients and their understanding of diabetes were significantly correlated with self-management of diabetes mellitus. Understanding of diabetes and self perception were significantly correlated with self-management in middle aged group. In the elderly group, intrinsic motivation, understanding of diabetes and the attitude of the patients were significantly correlated with self-management Conclusion: In the middle aged group, maintaining a positive attitude of diabetes, reducing stress and continuous social support were important for improving self-management of diabetes mellitus. In the elderly group, enhancing their knowledge of diabetes, and maintaining continuous social support were important to improve self-management of diabetes mellitus.

Objective: The objective of this study was to evaluate the physicochemical, sensory and taste characteristics of commercial, frozen, dry, and wet aged Hanwoo sirloin. Methods: Grade 2 sirloin from 6 Hanwoo steers (about 30 months old) were obtained after 5 days postmortem. Samples were assigned to four groups which were commercial beef (CON, control group), frozen beef (Hanwoo frozen, HF; 40 days in $-18^{\circ}C$ freezer), wet-aged beef (Hanwoo wet-aging, HW; 21 days), and dry-aged beef (Hanwoo dry-aging, HD; 40 days). HW and HD were stored in a $80%{\pm}5%$ relative humidity cooler at $1^{\circ}C$. Results: The HF group showed a significantly higher cooking loss and expressible drip with significantly higher pH compared to other groups. In addition, protein and fat contents in the HD group were higher than those in other groups (p<0.05). The shear forces in the HW and HD groups were significantly lower than those in the CON group. The HD group had significantly higher omega-3 and polyunsaturated fatty acids compared with other groups. Glutamic acid levels in the HD group were significantly higher compared with those in other groups. Electronic tongue analysis revealed that sourness of the HD group was lower than that of other groups, whereas the HD group showed significantly higher umami, richness, and saltiness compared to other groups (p<0.05). Sensory test results revealed that the HW group had significantly higher tenderness, while the HD group had significantly higher chewiness, juiciness, and overall acceptability scores. Conclusion: These results suggest that both wet- and dry-aging treatments can effectively improve sensory characteristics, and dry-aging was much more useful to enhance umami tastes and meat quality of 2 grade Hanwoo sirloins.

This study was performed to investigated the effect of dietary fat sources on renal senescence in aged rats. Seventeen month old male Sprague-Dawley rats were divided into 3 groups according to urinary protein excretion. Four month old rats were used as a control group. The rats were fed one of three different experimental diets ; 20% beef tallow, 20% corn oil 20% fish oil diet. They were fed experimental diets ad libitum for 16 weeks . The results are summarized as follows. Serum lipid concentrations were higher in aged rats than in control rats, with the beef tallow group showing the highest level, followed by the corn oil and fish oil groups. Old rats showed higher HDL and lower LDL levels than the control groups. Age and dietary fat had no effect on VLDL. GFR for the both age groups were increased with experimental period with the beef tallow group showing the highest value. Urinary protein excretion was also increased with experimental period in both age groups. There was a large increase in urinary protein in old rats that were fed beef tallow and corn oil, but not in old rats fed fish oil. On the contrary , the effect of dietary fat on urinary protein was not found in control groups. There was individual susceptibility in the effect of dietary fat on urinary protein. Old rats fed beef tallow with high initial urinary protein showed highest increase, but , the change was not significant in rats with a low initial value . It was also found that the increase was kept low in rats of the fish oil group with high initial urinary protein. The corn oil group showed in between values. There were no differences in urine and renal tissue concentrations of TXB2 . Aged rats showed a tendency of having higher urinary PGE2 excretion and lower renal cortex content. Since higher PGE2 excretion was reported to be associated with decreased renal function, this might suggest that the aged rats show renal function reduction. Light microscopic examination showed that glomerular segmental sclerosis, mesangial matrix expansion and tubular atrophy were more frequently present in aged rats, and that these changes were more significant in the beef tallow group, followed by corn oil and fish oil groups. The percentage of urinary protein excretion was increased in aged rats in association with increased glomerular sclerosis and mesangial matrix . This change could be partly due to a change in eicosanoids metabolism . Therefore, modification of dietary fat could affect the eicosanoids metabolism in kidney and renal senescence.

Objectives : The purpose of this study was to investigate the anti-oxidative effect of Suhwagije-decoction (SGT) pharmacopuncture solution on the liver and spleen cells of aged rats. Methods : The liver and spleen cells of 10, 52, and 72 week old Sprague Dawley (SD) rats were divided into three groups: distilled water (DW), Vit.C, and SGT groups, which were treated with DW, Vit.C and SGT pharmacopuncture solution respectively. The levels of superoxide dismutase (SOD), glutathione (GSH) and nitric oxide (NO) were then measured. Results : 1. Treatment of SGT pharmacopuncture solution significantly decreased NO concentration in spleen cells of 52 week old rats as compared with that of other groups. 2. Treatment of SGT pharmacopuncture solution significantly increased SOD activity in spleen cells of 72 week old rats as compared with that of other groups. Conclusions : Suhwagije-decoction (SGT) pharmacopuncture solution may have an anti-oxidative effect in the spleen cells of aged rats.

A study was performed to investigate the degree of similarities and differences in components of craniofacial complex between Korean twins and normal children by lateral cephalometric analysis. Dimensions of S-N, S-Ba, N-Ba, Go-Me, Ar-Go and Ar-Me were against linear measurement and angles of N-S-Ba and gonial against measurement in twins and control groups. The lateral cephalograms of twin were composed of 88 twins aged from 7 to 12:44 males aged 10.65 and 44 females aged 9.55, while those of 50 normalities were composed of 25 males and 25 females aged 10.9 respectively. In order to analyze growth proportion and sexual differences, twins were divided into 3 groups according to two year age intervals and the author compared male with female in 3 groups. For the purpose of observing similarities and differences in twins and normalities by sex, total twins were compared with normalities. The obtained results were as follows: 1. There was no difference in craniofacial complex between plotted angular normalities. 2. In general, the measurements of male were larger than both twins and normalities, but there were no statistical sexual differences in both groups. 3. The growth proportion of mandible by aging was larger than that of face twins and those of female significances of in twins. 4. The growth pattern of gonial angle showed slightly reducing tendency in twins by aging. 5. There was little difference in the growth proportion of both male and female.

Purpose: The purpose of this study was to develop a program promoting adjustment to hospital life and determining its effectiveness for school aged children. Method: The sample group consisted of 76 hospitalized children in 2 University Hospitals located in Busan. The experimental group was given the program on admission and feedback was obtained on the 3rd day and again 24 hours later. Data was analyzed using t-test and ANOVA in the SPSS program package. Result: There were significant differences, in information(t=4.235, p=0.000) and coping effort criteria (t=2.922, p=0.005) between the experimental and control groups. There was a non-significant difference in attitude criteria between the two groups(t=1.009, p=0.316). Conclusion: It was found that the adjustment promoting program for hospital life for school aged children was effective, but not enough to promote self-esteem. The program, based on a learning theory, was improved and shown to be an effective and strong method to promote adjustment of school-aged children.

The purpose of this study was to investigate effect of living condition and aging on food intake in Korea. 98 free-meal receivers and 81 members in well-being center for the aged were asked about their food frequency and food consumption and their socioeconomic status by a questionnaire. All data were analyzed by SPSS (Statistical Packages for the Social Sciences) 10.0 program. There were statistical differences of living condition, marital status, former job and teeth status between free-meal receivers and people with stable lives. Moreover, all age groups of free-meal receivers had lower income, living expenses, educational period and frequency of physical activity than those of people with stable lives. But smoking and drinking was much higher in free-meal receivers. Arthritis was the most prevalent disease in both groups. And free-meal receivers had higher blood pressure and lower Body Mass Index than people with stable lives. Food consumption of free-meal receivers was definitely lower than that of people with stable lives in terms of food frequency and standard amount of food eaten. But noodles, bean sprouts and eggs were very important foods for free-meal receives. Food consumption of the aged was affected by age, educational period, income, blood pressure, duration after retirement, frequency of physical activity and Body Mass Index. Therefore, as various socioeconomic status affects on food intakes of the aged, more effective and practical nutritional programs which consider the receivers'socioeconomic status are needed for the nutritionally at-risk groups like the aging free-meal receivers.

The purpose of this study was to compare the body compositions and food behaviors of middle aged men with different obesity indices. The subjects were 62 middle aged men who lived Gunsan city. Heights, body weights, soft/lean masses, fat masses, percentages of body fat, and fat distributions were measured. Food habits and health-related lifestyle habits were evaluated based on questionnaires. The subjects were assigned to one of the following groups based on their percentage of body fat ($\%$Fat) ; normal, overweight and obesity. The results were as follows: their heights, fat masses, percentages of body fat, WHR, RBW, BMI and fitness scores were significantly higher in the obese subjects when compared to the normal and overweight subjects. Self-perceptions of weight and desires of weight control were significantly related with their percents of Fat. The overweight and the obese groups skipped meals, ate supper out, ate snacks, smoked tobacco, and exercised less frequently than the normal group. There were no significant differences in the scores of the dietary habits and drinking of alcohol among the three groups. Therefore, proper nutritional education on regular meals and intervention is required if middle aged men want to be of normal weight and have healthy lifestyles.
