This research is the trial for the computation of the ease-rate for the bodice pattern. The result of the analysis about the cross section figures of garment space by using a 3-D measuring instrument is that: The garment space of each bodice by each body size is definite. In the figure of cross section of the basic lines, an area of cross section of garment space and length of cross section of garment space are not increased in proportion to an area of cross section of the body. The ease rate is the same no matter that flat-rate of the body is same or different. The ease-rate is computed by length of cross section of garment space that is in proportion to the radius of the body.

Swim up fry of the Nile tilapia, Oreochromis niloticus, were fed 0 or 60 mg l7-methyltestos­terone (MT) per kg feed for 30 days. Fish that had been fed 0 or 60 ppm MT for the first 30 days were subsequently fed a commercial diet for 56 weeks to evaluate growth, survival, sex ratio, body composition, gonadosomatic index and the total edible portion. Mean body weight of MT treated group and untreated group were 1.7 g and 1.1 g, respectively at the end of the treatment for 30 days $(P<0.05)$. The experiment was terminated after a total of 60 weeks, the mean body weight of the MT treated population was 1,016 g and that of the untreated population was 762g $(P<0.05)$. However, the final mean body weight of untreated males (l, 086g) was not significantly different from treated males (l,016 g), but the mean body weight of the female group was 512 g. Therefore, the reason for the lower mean body weight of the untreated group was entirely due to stunted females. The percentage fillet yield of MT treated fish$(34.6\%)$ was not significantly different from that of the untreated males $(34.4\%)$, but the untreated females were lower than those of both treated and untreated male groups $(32.4\%)$ (P<0.05). There were no significant differences in the percentage of the all edible portion (AP) between MT treated and untreated males, but females were lower than males. Females are smaller fish in size and the gonads are larger in proportion which were discarded along with the intestine this explains the observed difference. Total biomass of the two groups were 134.8kg and 104.5kg per $m^3$, respectively. The proportion of fish reaching a marketable size of over 800 g in body weight within 14 months were $78\%$ in the MT treated group and $41\%$ in the untreated group.

화력발전소에서 배출되는 바닥재와 준설토를 70:30(wt%)로 혼합하고 이를 $6{\pm}2mm$ 크기 구형으로 성형 및 로터리 킬른에서 $1125^{\circ}C$/15 min으로 소성한 뒤, 그 물리적 특성을 평가함으로써 오염 토양을 복원하는데 사용되는 흡착제로의 적용 가능성을 분석하였다. 제조된 소결체(BD)는 100 ${\mu}m$ 이상의 거대 기공 및 10 ${\mu}m$ 이하의 미세기공을 모두 가지고 있었으며, 비표면적, 기공율 그리고 공극율은 각각 $12.0m^2/g$, 30.1%그리고 38.2%이었다. BD 소결체를 한번 분쇄한 시편(BD-C)은 종횡비$\fallingdotseq$2의 부정형이었으나, 부피비중 및 기공크기 분포는 BD와 비슷한 값을 나타내었다. 한편 BD-C 시편의 비표면적, 기공율 그리고 공극율은 BD에 비해 더 우수한 값을 나타내었는데 이는 내부에 존재하던 폐기공(closed pores)이 분쇄과정에서 개기공(open pores)으로 변환되면서 겉보기 부피가 감소했기 때문이다. 제조된 소결체의 영 전하점(IEP)는 약 pH=5이었고 따라서 미생물을 소결체에 결합시킬 때 반응용액의 최적 pH를 알 수 있었다. 본 연구에서 제조된 소결체는 오염 토양 복원에 사용되는 흡착제로의 적용이 가능하며, 더구나 측정된 데이터를 이용하여 BD와 BD-C를 적절한 비율로 혼합하면 적용 상황에 따라 다른 공극율, 기공율 등의 요구 조건을 최적으로 맞출 수 있을 것으로 기대된다.

When our body is immersed in water, we experience weightlessness. The degree of weightlessness that we experience varies depending on the proportion of the body immersed in water, being governed by the relationship between the weight of body and the buoyant force acting on the body. Human body during the performance of swimming in no exception to these influences. Swimmers body is subject to a time and position dependent force system. Even the magnitude of the buoyant force acting on the swimmers body at every given instant and the corresponding position of the CB change continuously. The findings of this study support the following conclusions. The buoyancy torque was the primary source of bodyroll exhibited by front crawl swimmers performing at distance pace, accounting for 88 % of the bodyroll. Faster swimmers used buoyancy more effectively to generate bodyroll, partially supporting the postulation that an effective use of buoyancy for bodyroll may reduce the generated hydrodynamic forces to be wasted in non-propulsive directions and maximize forward propulsion.

This study was conducted to examine the differences in perceived body weight and image and various lifestyles based on the self-rated health of university students when gender was adjusted. Five hundred fifty-five participants were asked their perceived health condition, and 58, 289, 160 and 48 students answered themselves as "very healthy", "healthy", "normal", and "unhealthy", respectively. As compared to the other 3 groups, "unhealthy" group showed higher proportions in dissatisfaction of body weight and negative perception of body image (P < 0.01). As health related lifestyles, "very healthy" group reported longer sleeping time than "unhealthy" group (P < 0.05), and had a higher proportion of people with regular exercise. Among the dietary behaviors, the frequencies of followings significantly different among the groups: "Regularity of meal time" (P < 0.01), "Eat protein foods more than twice a day" (P < 0.001), "Eat vegetables" (P < 0.01), "Eat fruit and fruit juice" (P < 0.01), "Eat vegetable oil added foods" (P < 0.01), "Eat seaweed" (P < 0.01), "Eat breakfast" (P < 0.01), "Modulation in animal fat and high in cholesterol intake" (P < 0.01). Particularly, higher proportion of subjects answered "very healthy" had higher frequencies (6-7 times/week) of these dietary behaviors. Overall results suggest that healthy lifestyle including adequate sleeping time, regular exercise, and good dietary behaviors might be potential factors affecting positive perception of health. In addition, positive perception of body weight and image were related with positive perception of health.

PURPOSE: This investigation in the study aimed to assess to determine proportion and susceptibility makers of sarcopenia in Korean younger female aged 30 to 39 years. METHODS: To address the complex sampling design of Korea National Health and Nutrition Examination Surveys, appropriate individual weights were incorporated into the analysis. The data employed a stratified, clustered, multistage probability sampling design. A total of 2,098 participants were enrolled and categorized into two groups based on their skeletal muscle mass index scores. One hundred and twenty-four individuals were placed in the sarcopenia group, while 2,024 were allocated to a normal group. The study examined various markers as variables, including age, height, weight, body mass index waist circumference, skeletal muscle mass index, systolic and diastolic blood pressure, fasting glucose, triglyceride, and total cholesterol levels, and smoking and drinking habits. RESULTS: The study found that proportion of sarcopenia in this population was 3.78% (CI: 2.89-4.94) in sarcopenia group and 96.22% (CI: 95.06-97.11) in normal with weighed values. Several susceptibilities including height, weight, BMI, waist circumference, diastolic blood pressure, and total cholesterol levels were risk factor for sarcopenia (p < .05), exhibited significant differences between the sarcopenia and normal groups. CONCLUSION: This investigation provides the proportion of sarcopenia and identifies relevant susceptibility markers among community dwelling younger women in Korea.

Background: Dietary fats can alter the deposition and distribution of body fats in ruminants. The deposition and distribution of body fat play a vital role in the quality of ruminant carcasses and are of great commercial value since they influence the profitability and consumer acceptability of ruminant meat. The current study examined the effects of dietary blend of 80 % canola oil and 20 % palm oil (BCPO) on carcass characteristics, meat yield and accretion of fatty acid (FA) in subcutaneous, omental, perirenal, and mesentery adipose depots and m. supraspinatus (SS) in goats. Methods: Twenty four Boer crossbred bucks (BW $20.54{\pm}0.47kg$) were randomly assigned to diets containing on DM basis 0, 4 and 8 % BCPO, fed for 100 d and harvested. Results: Diet had no effect (P > 0.05) on slaughter weight, dressing percentage, carcass and non-carcass components, meat yield, color, moisture and carotenoid contents and weight of adipose tissues in goats. The proportion of C18:1n-9 and cis-9 trans-11 CLA in the omental, perirenal and SS was higher (P < 0.05) in goats fed 4 and 8 % BCPO compared with the control goats. Dietary BCPO reduced (P < 0.05) the proportion of C14:0 in the omental, perirenal and mesentery depots, C18:0 in the perirenal depot, C16:0 in the SS and C16:1n-7 in the SS, omental and perirenal tissues. Dietary BCPO enhanced the proportion of C18:1 trans-11 Vaccenic and C18:3n-3 in SS and C20:5n-3 in SS and mesentery depot. No significant changes were found in the FA composition of subcutaneous depot. Conclusions: Results indicate that dietary BCPO can be utilized to alter the FA composition of adipose tissues without detrimental effects on carcass characteristics in goats. Nonetheless, dietary BCPO is not an effective repartitioning agent for body fats in goats.

This study was initiated to develop a methodology for devising Korean virtual models for apparel shopping at internet shopping site. The data base for this study was the Korean National Anthropometric Survey in 1997. The subjects were 493 women and 626 men in 20's. The researchers also measured 88 males and females in age 20's to suggest back and front depth proportions which are not available from the survey. The virtual models' figure types were classified by the heights, drop value and bust(chest) girth. It was evaluated whether it is needed to separate figure type with bust(chest) girth. The body sizes of virtual models were suggested for side view model and front view model in 13cm height. Four female virtual models were suggested for front view and side view. Eight male virtual models were suggested for front view and side view. Each virtual model's height, breadth and depth proportions were calculated. Shoulder breadth. Bust(chest) breadth, waist breadth, hip breadth and proportions were calculated for front view model. The bust(chest) depth, waist depth, abdomen depth, hip depth and proportions were calculated for side view model. Height proportions were suggested for female and male virtual models.
