Objectives: This study aims to reveal the relationship between social relations and physical activity in the young-old and old-old elderly. Methods: Data from 2020 National survey of Older Koreans were used, and a total of 10,097 subjects over the age of 65 were included in analysis. The dependent variable was physical activity, and the independent variables were social relations barrier and motivational factors. x²-test and binary logistic regression were performed for data analysis. Results: The physical activity rate in the elderly were 40.8% in the young-old and 29.2% in the old-old. The socio-demographic characteristics affecting physical activity were the young-old elderly were sex, residential area, employment status and household income, and the old-old elderly were sex, age, residential area, education level and household income. The social relations barrier factors affecting physical activity were the young-old elderly were number of close friends, family care, exercise information search and video viewing, and the old-old elderly were household type, number of close friends, participation in exercise education, exercise information search and video viewing. The social relations motivational factors affecting physical activity were the young-old elderly were call with children/relative/friend, participation in sports activity, access time from home to parks, and the old-old elderly were call with children/relative/friend, participation in sports activity, satisfaction with green spaces. Conclusions: It was found that social relations barrier and motivational factors of the elderly are important factors to consider when developing physical activity promotion strategy, and there are also difference between the age of the elderly.

Purpose: The purpose of this study was to investigate the nutritional status of 3~5 year old children attending kindergarten and childcare facilities in 2010 and 2014. Methods: Data were obtained from the 2010 and 2014 Korea National Health and Nutrition Examination Surveys (KNHANES) and included 509 subjects aged 3~5 years old attending kindergarten and childcare facilities. Results: In 2014, rate of skipping meals by children was 16.2%, an increase of 5.5% compared with the rate of skipping meals by children in 2010. Calcium intake in 2014 was 397.41 mg at 3 years old, 419.27 mg at 4 years old, and 414.01 mg at 5 years old. For the mean nutrient adequacy ratio (MAR) of subjects in 2010 and 2014, MAR at 3 years old (0.86) was significantly lower than those at 4 and 5 years old (0.90, 0.91) (p < 0.01). In 2010 and 2014, EAR intake at 3 years old (2.72) was significantly higher than those at 4 years old (2.14) and 5 years olds (1.92) (p < 0.01). Conclusion: As a result, compared with 2010 before establishment of the Children's foodservice management center, there was no improvement in the polarization of nutrient intake of children in 2014. Therefore, researchers believe that a continuous monitoring system developed by nutrition experts and children's foodservice management center are needed to improve the nutritional status of children. Of children between the ages of 3~5 years old, those with intakes under EAR were mostly 3 years old. Therefore, researchers suggest that the infant age group of KDRIs, which is classified as 1~2 years old and 3~5 years old, needs to be reestablished considering the growth and development of infants.

Morphological difference of the renal glomerulus at different age groups have been studies in one week-old, five weeks-old, eight weeks-old, six months-old, twelve months-old, eighteen months-old, twenty-four months-old, and thirty months-old ICR mice. Pieces of the tissue taken from the renal corticies were fixed in 2.5% glutaraldehyde-1.5% paraformaldehyde solution (0.1 Millonig's phosphate buffer pH 7.3), and 1% osmium tetroxide solution (0.1 M Millonig's phosphate buffer, pH 7.3), and were embedded in araldite mixture. The ultrathin sections were stained with uranyl acetate and lead citrate solution, and were observed under a JEM 100CX-II electron microscope. The results were as follows: 1 In the one week-old mouse, thicknesses of the three layers of the glomeluar basal lamina (lamina densa, lamina rara interna and lamina rara externa) are similar, but in the five weeks-old mouse, thick lamina densa becomes a greater portion of the thickness of whole glomerular basal lamina. 2. No difference was noticed between thickness of the renal glomerular basal lamina of the five weeks-old mouse compare with that of the one week-old one, but basal lamina of the eight weeks-old one is thickened considerably and thicknesses were maintained through twelve months-old one. After eighteen months, the thickness of the glomerular basal lamina is increased remarkably. 3. After eighteen months, electron dense deposits within the basal lamina of the renal glomeruli are observed frequently. 4. Amount of the microfilaments in the mesangial cells and the mesangial matrices are increasing during aging. 5. The thicknesses of the basal laminae of the Bowman's capsule are increasing during aging. 6. After twenty four months, the proximal tubular cell-like parietal cells with well developed microvilli are observed frequently. From the above results, it was suggested that the renal glomerulus matures structurally in five weeks, and the function of the glomerulus is suppressed after eighteen months.

Methods The study was conducted on the subjects inputted /a/ 2.5-3 sec of 217 adult women voices to PSSC-2004. The statistical analyses are applied to three groups: total group, under 55 year-old group, over 55 year-old group. The group of total 216 was composed with 8 Taeyangins, 60 Soyangins, 66 Taeumins and 83 Soeumins. The under 55 year-old group was composed with 6 Taeyangins, 53 Soyangins, 55 Taeumins and 76 Soeumins. The over 55 year-old group was composed with 2 Taeyangins, 7 Soyangins, 11 Taeumins and 7 Soeumins. Results 1. In total group and under 55 year-old one, Soeumin's center pitch were significantly high compared with the others(P=0.005)(P=0.019). It was significant for distinction between Taeumin and Soeumin at the result of post mortem. 2. In over 55 year-old group, Soeumin's center freq.(total) and center freq.(1) were significantly high compared with the others(P=0.024)(P=0.016). In under 55 year-old group, Soeumin's center freq.(4) was significantly high(P=0.025). While Taeumin's center freq.(3) in under 55 year-old group and center freq.(4) in over 55 year-old group were significantly high(P=0.049)(P=0.043). 3. In over 55 year-old group, Soeumin's APQ(center), APQ(2/5), APQ(3/5), APQ(4/5) and APQ(2/3) were significantly high compared with the others. It was significant for distinction between Taeumin and Soeumin at the result of post mortem(P=0.004) (P=0.003) (P=0.004) (P=0.013) (P=0.004). 4. In over 55 year-old group, Soeumin's APQ(1/3), APQ(1/2), APQ(2/2) and zeroover APQ were significantly high compared with the others (P=0.013) (P=0.003) (P=0.008) (P=0.012). 5. In over 55 year-old group, Taeyangin's octave 3 shimmer was significantly high compared with the others(P=0.000). 6. In under 55 year-old group, Taeyangin's total energy was significantly high compared with the others(P=0.040). 7. In under 55 year-old group, Taeyangin's zeroover energy sum was significantly high compared with the others(P=0.038). Conclusions From above result, there is the possibility of efficiency standard guide for constitutional diagnosis by analyzation of the voices.

Due to the ageing-related degradation in physical and cognitive abilities, the elderly have difficulty in car driving and this is related to the high rate of car accidents among them. This study investigated the kinematic characteristics of old drivers' steering in right turning at intersections by comparing with young drivers. Thirteen old(60~70) and thirteen young(20~30) drivers who participated in the experiment turned their cars right side at intersections in a driving simulator. As results, the completion time of right turning at intersection of old drivers was larger than that of young drivers. The speeds of vehicle at the beginning and ending point of the right turning area of old drivers were smaller than those of young drivers, and also the steering angle at the ending point of the turning area of the former was smaller than that of the latter. The normalized jerk of old driver's steering was significantly larger than that of young drivers. These results indicate that old drivers modify their steering movement repeatedly and take the driving strategy of avoiding risks due to their reduced physical capabilities.

Purpose: This study was conducted to identify the differences of health patterns; health-related characteristics, health behaviors, health problems, and self-care levels of elderly, living alone in an urban area according to age roup. Method: The study design was a descriptive survey and the subjects were 1,800 elderly consisting of 937 young old, 704 middle old, and 159 old old. Data was collected from May to July 2003 using the structured questionnaire and analyzed by descriptive statistics, $\chi$$^2$-test, Fisher's exact probability test, ANOVA and Scheffe test using SPSS/PC. Result: The health related characteristics which involved body mass index, mental status, use of assistant devices, perceived health, concern of health, and social support were different among the groups and more aggravated by aging. Health behaviors and health problems were also significantly aggravated in the old old group. The self-care levels measured by ADL, physical activity, and self-care ability scores were also significantly decreased in the old old group. Conclusion: For the level of health status, health behaviors and self-care ability were significantly decreased by aging, health care services for the elderly should be planned considering the difference in the health pattern by age group.
