This study analyzes the perception of the old age life effects on the preparation for old age plan for veterans who are somewhat isolated from our society in spite of the increasing importance of the old age plan due to the rapid population aging society in Korea. The result of the study shows that meaningful differences in terms of characteristics of sociology of population are rank, level of education, religion, composition of family members in old age life plan in two parts(economic, leisure), whereas only property in physical part has a meaningful difference. That indicates the result was reflected by the character of military. The study on how veterans' perception of the old life affects the old age plan applied two contrasting factors - 'the successful perception of old age life' and 'the perception of expected matters in old age'. That represents those factors(economic, leisure) made positive effects on preparation for old age plan, but not in physical part. 'Expected perception of matters' made regulation effect, but 'success of old age perception' didn't in terms of regulation effect of learning activity as part of the veterans vocational training programs.

The purpose of this study was to investigate the difference of body composition and IADL of between male elder and female elder. (This study consisted of elder male(n=10) and elder female(n=10),) The mean age of elder male and female was 67.20, 67.50 years. The data were analyzed with t-test, using SPSS PC+ program. Body composition was measured using Inbody 2.0(seoul, korea) of segmental multi-frequency impedance analyzer technique. IADL was measured with Philadelphia Geriatric Center IADL. The result of this study were the following: 1. The difference of Body composition 1) The %fat of elder female was significantly(p<0.05) higher than elder male by 11.48%. 2) The fat mass(kg) of elder female was significantly(p<0.05) higher than elder male by 6.28kg. 3) The free fat mass(kg) of elder male was significantly(p<0.05) higher than elder female by 9.03kg. 4) The muscle mass(kg) of elder male was significantly(p<0.05) higher than elder female by 8.63kg. 5) The WHR(%) elder female was no significantly higher than elder male by 0.03%. 6) The TBW(l) of elder male was significantly(p<0.05) higher than elder female by 6.321. The factor of significant difference of between elder male and female was %fat, fat mass(kg), free fat mass(kg), total body water(l). 2. The difference of IADL 1) IADL of elder male was no significantly higher than elder female by 1.20. As a result of this study, optimal body composition group was elder male group. Optimal body composition of elder had improved IADL. In addition to, this result of this study, it can suggested the consideration of the Health promotion program for elder.

An experiment was carried out to determine the effect of age and caponization on the development blood and bone characteristics development in male country chickens in Taiwan. A total of two hundred 8-wk-old LRI native chicken cockerels, Taishi meat No.13 from LRI-COA, were used as experimental animals. Cockerels were surgically caponized at 8 wks of age. Twelve birds in each group were bled and dressed from 8 wks to 35 wks of age at 1 to 5 wk intervals. The results indicated that the plasma testosterone concentration was significantly (p<0.05) lower in capons after 12 wks of age (caponized treatment after 4 wks) than that of the intact males. The relative tibia weight, bone breaking strength, cortical thickness, bone ash, bone calcium, bone phosphorus and bone magnesium contents were significantly (p<0.05) higher in intact males, while capons had higher (p<0.05) plasma ionized calcium, inorganic phosphorus and alkaline phosphatase concentration. The plasma testosterone concentration, relative tibia weight, tibia length, breaking strength, cortical thickness, bone ash, calcium, and phosphorus contents of intact males chickens increased significantly (p<0.05) with the advance of age. In addition, the relative tibia weight of capons peaked at 18 wks of age, and declined at 35 wks of age. The bone ash, calcium and phosphorus content increased most after 14 wks of age in male native chickens in Taiwan. Also, tibia length and cortical thickness peaked at 22 wks of age. However, the peak of bone strength was found at 26 wks of age. These findings support the assertion that androgens can directly influence bone composition fluxes in male chickens. Caponization caused a significant increase in bone loss at 4 wks post treatment, which reflected bone cell damage, and demonstrated reductions in the relative tibia weight, breaking strength, cortical thickness, bone ash, calcium, phosphorus and magnesium contents, and increases in plasma ionized calcium, inorganic phosphorus and alkaline phosphatase concentration.

An experiment involving 180 straight run one-day-Cobb broilers was conducted to evaluate the effect of supplementation of L-leucine with different levels of crude protein (CP) on carcass composition and sensory characteristics of broiler grower-finisher chickens. Six experimental diets comprising two levels of crude protein (CP) i.e., 20 and 20% with three levels of L-leucine i.e. 0, 0.5 and 0.67%, were offered to birds from 21-42 d of age. The birds were randomly divided into 36 experimental pens, 5 chickens in each pen, and there were 6 replicates under each diet. L-leucine supplementation did not affect the bone and lean, whereas fat was decreased (p<0.05) when L-leucine was added at 0.5%. Similarly, there were no significant differences (p>0.05) in the lean, fat and bone among chickens fed two levels of CP. No significant differences between dietary treatments were observed on any sensory characteristics affected by dietary L-leucine and CP. From this study, it is obvious that supplementation of up to 0.5% L-leucine reduced fat. However, other characteristics were not affected by supplementation of L-leucine. Similarly, reduction of body composition and sensory characteristics were not apparent on a diet low in CP.

Heat stress is major welfare problem in the poultry industry. Huge economic losses occur every year because of mortality and decreased production due to high environmental temperatures. This experiment was conducted to determine the effects of level of inclusion of ascorbic acid supplementation to the diet on performance, carcass composition and bone characteristics of male turkeys during high summer temperature. A total of 120 day-old turkey chicks were wing banded at hatch and randomly distributed into 3 treatment groups. Three diets were formulated to provide a similar nutrient profile with the exception of using three graded levels of ascorbic acid, namely 0, 150 and 300 mg/kg of the diet. The experimental diets were used from 0 to 18 weeks of age. Body weights, feed intake and feed conversion ratio, slaughter weight, carcass yield, portions, composition and thigh and breast pigmentation of the turkeys were not affected by ascorbic acid (p>0.05). Also, shank and tibia bone characteristics were not affected by ascorbic acid (p>0.05).

The purpose of this paper is to examine and analyse the features of plan type and space composition of the Siheyuan(courtyard house) which is one of the most remarkable types of the traditional dwellings in China. With the passage of time this house developed into one of the chinese house style. The technique of Siheyuan's spatial composition goes so far back in the New Stone Age. The relics of this are the colony layout, the system of four sides, the layout type of a palace, the picture of lacquered ware, the pictured brick, the earthenware of house type, the cave painting, the paintings of painters and others. The fundamental spatial conception of it arranges one or more courtyards to compose, sometimes in a very complex way, a general walled compound. The main longitudinal axis is mainly north-south, but the chief buildings, or halls are always placed transversely to it. These rectangular buildings mayor may not connect, by means of open galleries variously planned, with rows of smaller buildings flanking the courtyards on both sides. On this system, enlargement is never carried out by adding to height, but by continual duplication of existing units, and growth in breadth or preferably depth. The need for family security is thought to have led to the development of this rectangular houses with walls mainly blank on the outside, defensible entrances, and public service facilities in the center of the houses.

The aim of this study was to evaluate the body composition difference and obesity prevalence in grade 5 to 8 by gender. A total of 1,333 students, 707 boys and 631 girls, were recruited from one elementary and one middle school in Seoul, Korea. Anthropometric measurements including height, weight, lean body mass, and body fat were assessed. Height and weight were increased by grade, but Body Mass Index (BMI) by grade showed no significant difference among boys. Lean body mass had growth spurt between 7 and 8 grade among boys compared to gradual increase among girls. Overweight and obesity prevalence were higher among elementary schoolers than middle schoolers. Overweight (BMI for age> $85^{th}$ percentile) prevalence was about $44\%$ among $5^{th}$ grade boys compared $29\%$ among same grade girls. These results provided that there were prominent difference regarding body growth and obesity prevalence in gender and grade. Further studies for children and adolescents should be considered their body composition change.

The influence of $P_2O_5$ on clinker mineral composition and the cement quality was investigated. When the sewage sludge was used as a raw material in place of clay, the presence of $P_2O_5$ in sewage sludge affects the mineral composition and the clinker quality. As the $P_2O_5$ concentration in raw mix increases, the burnability of clinker becomes worse and the alite decomposes into belite and free-CaO, so belite increases with the decrease of alite. The early strength of mortar decreases with the increase of $P_2O_5$ concentration. On the other hand, later-age strength increases with the increase of belite content. The setting time of cement was delayed with the $P_2O_5$ concentration above 0.6 wt%.

This study considers the concept of schools and their spatial composition by John Dewey through literature review who argued for a new, children-centered education in the early 19th century, and it also mentions some suggestions for improvement of the elementary school facilities in Korea that the size and number of students in school has decreased sharply. John Dewey claimed that a school is a big household as well as a small society in which one studies the current occupation and experience in connection between the household-school-society. At the same time, he pursued an organic and open spatial composition which can effectively and efficiently enable educational curriculum's application, social occupation and project learning based on children's native impulse and stage in child growth. Korea's education policy should shift from quantity-based education production to quality-based production due to the reduction of school age population among other reasons. Especially this study emphasizes that small size schools need to be changed to local community facilities with environment-friendly, children-centered and open learning spatial composition with basis on John Dewey's educational philosophy.

The spatial composition of Korean traditional houses is based on the relation of spaces in the background of humanism, society, and composition. According to the analysis of it in this study, we make conclusions as follows; 1) Two compositive axises are formed according to age, sex and status which are the main factors of society and culture in the traditional society. 2) The house of '口-shaped' type in the traditional houses concentrates to the interior. To the exterior, it has the closed and conservative system. The wall in the outside of An-Chae intercepts the sight outward and the extension of space, while the wall in the inside is composed of doors and windows which make the sight and space concentrate to the interior. On the contrary, the doors and windows of Sarang-bang and Nu-maru of Sarang-chae open and extend to the exterior. 3) The spatial composition of the traditional houses is composed of geometrical order system and organic order system.
