  • The Principle of space composition in modern architecture is thought about functionalism that based on function and program but the present age attempt that escapes form of former space composition. The present age brings fast development than former ages, so we need the space which has correct flexibility on New Age for escaping in existing structural formality. Specially, the space that boundary of existing plate, column and wall is crumbled as becoming possible technological support with social backgrounds. What this study saying is the analysis about the relation between the concept of topology and the consecutive space composition. Therefore, there is the purpose understanding a characteristic of continuity of the plate through the topological concept and understanding the roll in interior space.

  • The fatty acid composition of muscle were investigated to compare muscle composition among the 9 domestic animals including cattle. In major domestic animals, analyzed the effects of age, part and sex of the animal on their fatty acid composition. The content of 4 types of major fatty acids of muscle was determined and calculated their ratio. Myristic acid and palmitic acid levels were high in chicken and sheep. Besides dog muscle contained a lot of stearic acid. Linoleic acid content showed evident difference in the content depending on the animal species. The ratios of linoleic acid/palmitic acid (L/P ratio) and linoleic acid/stearic acid(L/S ratio) were characteristically high in horse and pig, whereas the ratio of palmitic acid/stearic acid(P/S ratio) was $0.71{\pm}0.17$, showing very low level in dog. As for the content of stearic acid, in cattle and chicken it was higher in young animal than adults. In duck, the contents of all fatty acids and ratio were increased by the age. As for the content of fatty acids according to the part of chicken, high level was shown in thigh than in breast and wing, while there was no remarkable variation by the part in other animal. The differences in the content of myristic acid, palmitic acid and linoleic acid among some animal could be verified in muscle lipid composition. The L/P ratio which maintained certain level regardless of age, part, sex shown distinctive pattern between the species.

  • PURPOSE: This study examined the necessity of a musculoskeletal injury-prevention program for automobile parts manufacturing workers by assessing the body composition, muscle strength, and posture according to sex and age. METHODS: Two hundred eighty-two workers (men, 218; women, 64; mean age, 38.97 years; and mean work tenure, 10.29 years) participated in this study. They completed a questionnaire on their general characteristics, excluding personal identification codes. The participants were evaluated for body composition, muscle strength, and posture using InBody, a hand dynamometer, and the Image J program through photography, respectively. An independent t-test and one-way analysis of the variance were used for the comparisons according to sex and age, respectively. RESULTS: Significant sex-related differences in muscle strength and grip force were observed (p<.05). In addition, the left-side pelvic inclination was significantly higher in the female participants than in the male participants (p<.05). Significant age-related differences in the skeletal muscle mass and muscle strength were observed around 40 years (p<.05). Significant correlations were observed among the body composition (skeletal muscle and body fat masses), muscle strength, and posture (pelvic inclination; p<.01). CONCLUSION: Significant differences in pelvic inclination by sex and muscle strength by age were found, even in healthy workers. Additional posture and muscle strength measurements will be needed for workers who participate in the musculoskeletal injury prevention program because they are exposed to an incorrect posture for many hours or in many repetitive tasks.

  • This study purposed to identify the design and composition characteristics of mantle through a historical review of its change and development focusing on women's dress. This analysis was particularly focused on the Victorian age because the variety of mantle designs introduced and popularized was wider than ever since ancient times to the present. For this study, we collected historical literature on mantle from ancient times to the $19^{th}$ century and made comparative analysis of design and composition, and for the Victorian age we investigated also actual items from the period. During the early Victorian age when the crinoline style was popular, mantle was of A.line silhouette spreading downward from the shoulders and of around knee length. In the mid Victorian age from 1870 to 1889 when the bustle style was popular, the style of mantle was changed to be three-dimensional, exaggerating the rear side of the bustle skirt. In addition, with increase in women's suburban activities, walking costume became popular and mantle reached its climax. With the diversification of design and composition in this period, the name of mantle became more specific and as a result, mantle, mantelet, dolman, paletot, etc. were used. The styles popular were: it looked like half-jacket and half-cape. Ornaments such as tassels, fur, braids, rosettes, tufts and fringe were attached to create luxurious effects. In the late Victorian age when the hourglass style was in fashion, mantle returned again to plain design emphasizing the details of the shoulders. The results of this study are expected to present motives for the development of contemporary designs, to contribute to the new recognition of the value of mantles, and to open a new research area of clothing history.

  • The effects of castration on growth and body composition of Javan rusa (Cervus timorensis russa) stags were examined at three slaughter ages in three experiments. Castration had no effects on growth rates, or liveweights at periodic weighings, at any stage in Experiments 1 and 2, when the stags were slaughtered at 19 and 13 months of age, respectively. In Experiment 3, monthly liveweights of castrated and entire stags were not significantly different until the stags were 21 months old. From this age, when they had recovered from their first rut season and were in their second spring/early summer, the entires grew more rapidly than the castrates. There were seasonal changes in growth in both treatments, indicating that pasture conditions influenced performance. Liveweights of entires and castrates were similar in stags slaughtered at 13 and 19 months, but castrates were smaller than entires at 25 months. Castration reduced the size of the head and skin, but there was little important effect of castration on body components at any slaughter age. Castration can be recommended as a management tool for rusa stags, especially if the animals are to be slaughtered before they exceed 19 months of age.

  • Osteoporosis is a disease that increases the fracture rates and a major cause of increased mortality and morbidity in the elderly people. This study is to determine which components of body composition and metabolic syndrome risk factors are important to bone health, we analysed the relationship among bone mineral density (BMD), body composition and metabolic syndrome risk factors in females. Totally 630 females participated in a medical check-up program (mean age 47 years) were selected for this study. Body composition analysis was performed by segmental bioelectrical impedance method, muscle mass, and percent body fat were measured. We also measured metabolic syndrome risk factors including abdominal obesity, HDL-cholesterol, triglyceride, blood pressure and fasting glucose level. Metabolic syndrome was defined by NCEP-ATP III criteria. The lumbar spine and femoral neck BMD were measured using the dual energy X-ray absorptiometry. Osteopenia and osteoporosis were observed in 180 and 51 persons, respectively. Muscle mass and HDL-cholesterol decreased in osteopenia and osteoporosis groups compared to the control group, and the grade was shown progressively by the symptoms. Significant positive correlation between BMD and muscle mass was observed. Multi variable regression analyses showed that % body fat and muscle mass were independent predictors of BMD after adjustment of age, height and weight. In conclusion, the BMD showed negative correlation with the metabolic and body composition was associated with BMD.

  • In this study, batcher plant composition test and mock-up test were carried out to conduct comparison and analysis on flow behavior and strength properties of concrete at early age. As a result, it was found that slump and amount of air in batcher plant composition test reached the target range. As for compressive strength, composition using HESPC showed the most excellent strength development. In mock-up test which was carried out to find out the strength properties, two methods with specimen and core test body both revealed HESPC as the most excellent composition. However, strength estimation with ultrasonic survey presented less reliable data. As a result of the previously conducted indoor composition test and the mock-up test in this study, target performance of concrete at early age was 4day/cycle. It was found that the optimum conditions that meet the required strength, 5MPa/18hr and 14MPa/36hr in mullion and transom are; curing temperature above 15℃, W/B 45%, unit-water 165kg/㎥ and CHC cement.

  • This study was carried out to investigate the distribution of body composition, and to analyze its relationship to dietary behaviors and life style. The study subjects were divided into 3 age groups; 30' years (n = 78) 40' years (n = 71) and 50' years (n = 44). The data was collected by physical measurement (Inbody 230) and questionnaires. The rate of disease and general characteristics were higher in the 50 year old group than in the other groups. Average amount of body water, protein, mineral and body fat were 29.0 kg (50.4%), 7.7 kg (13.4%), 2.8 kg (4.8%), 18.7 kg (31.5%), respectively. The rate of menopause was significantly different with increasing age. Menopause was 1.3%, 9.1%, 79.6% by age respectively. Body fat percent was significantly increased and body water decreased with age (p < 0.01). The fat composition was higher and the mineral content was lower in 50' year old group. Dietary behavior scores of 30' year old group was significant lower than in the other two groups (p < 0.001). The means of salty eating, skipping meals, fruit intake and food habits total point were significantly higher in the 50 year old group than in the other groups. There were significant positive correlations between age, BMI, waist hip ratio respectively (p < 0.01). There were significant negative correlations between age and body water, body mineral, skeletal muscle (p < 0.01, p < 0.05, p < 0.01). The results of this study suggested that nutritional management and education for adult women differ by age group.
