Recently, there shows a trend in Korea that the rate of the population entering into aging is the most rapidly increasing among the OECD countries. Consequently, This study, therefore, aims at analyzing the forms of portfolio establishment by group, the factors affecting the old age preparation, and the presence of middle-aged households' preparation for the old ages in order to forestall social problems like the poverty ration of elderly that have been caused by the rapidly aging society. The result shows that the portfolio for the old age preparation can be expanded if a combination product of finance and real estate is developed as a means of old age preparation. Upon the results of the study above, it can be seen that the old age preparations differ according to not only the demographic elements, but also the extent to how much resources one holds. Especially, the various factors affecting the holding resources vary householder by household depending on whether they prepare for the old ages or not.

We present a study of the metallicities, ages, and alpha-elements of globular clusters (GCs) in nearby giant elliptical galaxies (gEs) (M87, M49, M60, NGC 5128, NGC 1399, NGC 1407, and NGC 4636) using data in the literature. We used only the data for the GCs derived from the comparison of absorption line indices with the single stellar population model. The metallicity distributions of GCs in these gEs are bimodal, showing the existence of metal-poor and metal-rich populations. All these gEs harbor young GCs with ages less than 5 Gyr as well as old GCs. The mean age of the metal-rich GCs ([Fe/H]>-0.9) is about 3 Gyr younger than that of the metal-poor GCs. The mean values for the alpha-elements of the GCs are smaller than or similar to that of the Milky Way GCs. All the GCs in these gEs show an age-metallicity relation; the larger the metallicities of the GCs are, the younger the GCs are. Old GCs with ages > 10 Gyr have two distinct sub-populations (metal poor and metal rich), while young GCs show a broad metallicity distribution with a single peak. We discuss these results in relation with the formation of GCs in gEs.

The purpose of this study was to compare the expectations of mothers and teachers regarding development of three-year-old children and to analyze factors influencing the expectations. The results of this study showed that the mothers held higher expectations than the teachers regarding development of their children in all areas. Maternal expectations differed depending on the ages of the mothers and their children's birth order. Teaching experience with three-year-old children also made differences in the teacher's expectations. Implications to parent education and suggestions for future studies were provided.

The study consisted of all patients undergoing surgical repair of isolated secundum type atrial septal defect in patients ages 35 years or older for the period from October 1986 to October 1991. ASD was closed with direct suture in all patients. Response to surgery was excellent. Two patients who had atrial fibrillation was taken low-dose warfarin therapy to prevent stroke. All patients survived operation, and improved by at least one New York Heart Association functional classification. An old age was not a contraindication to surgery.

Recently with increasing interest in the natural science history education, a lot of natural science museums have been developed in various locations. This project is located in one of the biggest Paleozoic site, Taebak Kangwon-do. This kind museum has had important rolls in terms of education for student, destination for traveling and reservation of important holdover of the old ages. To do those kind of parts, this project has been designed with concepts and themes like; i. being organized with story telling structure with theme "secret of life and earth from Taebak" ii. combining experiences between outdoor experimental search for the real fossils and indoor educational interactions with real size model and moving films. iii. designing with strong identities of Paleozoic era. For the design identities the outer appearance was designed with motive of trilbites in an abstract way and inside was finished with exposed concrete and various size of moving films projected to walls and floor to emphasize real scale experience of the old ages.

The purpose of this study is to investigate children's liquid conservation concept according to their ages and task-situations in the water evaporation phenomenon. Thirty from each 4-, 6- and 8-year-old age groups (total of 90 subjects) were selected for this study. The subjects were recruited from two day-care centers, a kindergarten, and an elementary school, in Seoul. Statistical methods used for data analysis were frequencies, percentiles, means, standard deviations and repeated measures ANOVA. As a result, there was a significant difference in children's liquid conservation concept in the evaporation of water according to their ages and task-situations. 8-year-old children showed levels of cognition than 4- and 6-year-olds. Children showed higher levels of cognition in the task of drying than in the task of water level changes.

Of 633 children, 334 in male and 299 in female, whose ages ranged from 3 to 13 years old, the amounts of development of teeth germ were observed according to ages with oblique lateral cephalogram to study the developing state of teeth germ of mandibular premolars. The results were as followings; 1. The time of actively develop:ng tooth germ was observed about 10 years old both in male and in female. 2. The increasing rate of development of tooth germ a year was higher in female than in male at mandibular 1st premolar and in male than in female at mandibular 2nd premolar. 3. Age of complete tooth germ development was earlier in female than in male at mandibular 1st and 2nd premolars.

Elderly Koreans(<60 year old) living in Seoul were surveyed with questionnaire to Investigate their nutritional status and those factors affected. The result could be summarized as follows : Mean energy intakes of elderly men and women were 1,528 and 1,292 kcal, and 79.1 and 65.5% of RDA, respectively. Below 215 of RDA were Ca and vile. A in men and Ca, vile. A and riboflavin in women. Compared with elderly men, elderly women showed lower quality of diet. In men intakes of nutrients were markedly decreased after 80 years old but in women these tendency showed more early stages of ages. The factors that had effect on nutrient intakes were age, height in men and SES, body weight and BMI in women.

The purpose of this paper is to explore some aspects of functional foods and to give an prospective view of the foods. Recently the increasing rate of old ages is very rapid so that the functional foods is demanded as the treatment of cure and health foods for the old ages. Those are the foods which includes such elements as polyphenol, vitamin E & C, 𝛽-carotene, selenium, lycopene, lutein, isoflavon, capsaicin, DHA, lecithin, peptide, dietry fiber, alginic acid, lactic ferments, caffeine, kitin and kitosan, taurine, and phenylalanine. The total amounts of those foods are $ 112 billion in 2001, the American market marks $36.3 billion (32%) and Europe marks $32.6 billion (29%) and Japan marks $27.1 billion (24%), however, Korea marks $11 billion which equivalent to 1%. We are in need to develop the new foods for the antioxidant effect, anti-cancer, the prevention of cardio vascular disease, the control of intestine vacillius, control of diabetes, with those functional elements in order to secure the world market for the functional foods.
