  • Objectives: The effects of peroxisome proliferator-activated receptor ${\gamma}2\;(PPAR{\gamma}2)$ Pro12Ala (P12A) polymorphism on body mass index (BMI) and type 2 diabetes are well documented; however, until now, only a few studies have evaluated the effects of this polymorphism on body fat distribution. This study was conducted to elucidate the effects of this polymorphism on computed tomography (CT)-measured body fat distribution and other obesity-related parameters in Korean female subjects. Methods & Results: The frequencies of $PPAR{\gamma}2$ genotypes were: PP type, 93.0%; PA type, 6.8%; and AA type, 0.2%. The frequency of the A allele was 0.035. Body weight (P .012), BMI (P .012), and waist-to-hip ratio (WHR) (P .001) were significantly higher in subjects with PA/AA compared with subjects with PP. When body composition was analyzed by bioimpedance analysis, lean body mass and body water content were similar between the 2 groups. However, body fat mass (P .003) and body fat percent (P .025) were significantly higher in subjects with PA/AA compared with subjects with PP. Among overweight subjects with BMI of greater than 25, PA/AA was associated with significantly higher abdominal subcutaneous fat (P .000), abdominal visceral fat (P .031), and subcutaneous upper and lower thigh adipose tissue (P .010 and .013). However, among lean subjects with BMI of less than 25, no significant differences associated with $PPAR{\gamma}2$ genotype were found, suggesting that the fat-accumulating effects of the PA/AA genotype were evident only among overweight subjects, but not among lean subjects. When serum lipid profiles, glucose, and liver function indicators were compared among overweight subjects, no significant difference associated with $PPAR{\gamma}2$ genotype was found. Changes in body weight, BMI, WHR, and body fat mass were measured among overweight subjects who finished a 1-month weight lose program of a hypocaloric diet and exercise; no significant differences associated with $PPAR{\gamma}2$ genotype were found. Conclusions: The results of this study suggest that the $PPAR{\gamma}2$ PA/AA genotype is associated with increased subcutaneous and visceral fat areas in overweight Korean female subjects, but does not significantly affect serum biochemical parameters and outcomes of weight loss programs.

  • Breed differences in adult animals are determined during fetal development. If interventions are to be developed that influence growth of muscle and fat, it is important to know at which time during gestation breed differences appear and are fixed. The objective of this study was to characterize fetal development in cattle of different breeds. Pregnant cows of 4 cattle breeds with different growth impetus and muscularity were slaughtered under normal processing conditions and the fetuses were removed. German Angus, a typical beef cattle; Galloway, a smaller, environmentally resistant beef type; Holstein Friesian, a dairy type; and Belgian Blue, an extreme type for muscle growth were used. Fetuses of each breed were investigated at 3, 6, and 9 mo of gestation. Fetuses were weighed and dissected into carcass, organs, and muscles. Body fat weight was obtained using the Soxhlet extraction method. Fetal weight increased most rapidly in the third trimester of gestation mainly due to the accelerated muscle and fat deposition. The organ weight to body weight (BW) ratios decreased and the muscle and fat weight to BW ratios increased. At 3 mo of gestation, Galloway fetuses had the significantly smallest BW, half-carcass weight, leg weight, organ weight, muscle weight and shortest leg length. In contrast, Holstein fetuses had the significantly greatest BW, liver, kidney, and lung weights and significantly longest leg length among the 4 breeds, but no differences between Holstein Friesian and Belgian Blue were detected in half-carcass and leg weight. Indeed, Belgian Blue fetuses had the significantly greatest half-carcass weight, leg weight, and muscle weight at 9 mo of gestation, and Galloway had a significantly greater body fat to BW ratio than Holstein Friesian and Belgian Blue. These differences were not evident at 3 and 6 mo of gestation. These data show that the profound increase of tissue and organ weights occurred in later gestation in cattle fetuses even though breed differences were evident as early as 3 mo of gestation. Depending on the tissue of interest, impacting fetal growth likely needs to occur early in gestation before the appearance of breed-specific differences.

  • This study was designed to investigate the effects of 8-week resistance exercise by using dumbell on the body com-position, serum hormone profiles and feeding patterns in young and healthy female students with over 30% of body fat, aged 22 years in Masan, Korea. The subjects were all six, performed successfully the entire exercise-program. Anthropometry, serum lipid and neurohormone profiles of subjects were analyzed at 0, 4 and 8 weeks after exercise. And also their food and nutrient intakes were self-reported by 3-day record and food frequency questionnaire. Triceps skinfold-thickness of the subject students significantly reduced after the exercise to 46% less than before (p < 0.002) . The serum concentrations of leptin, insulin and catecholamine appeared to decrease steadily, but not significantly. Total protein in serum increased significantly (p<0.05), and Na (p<0.005), K (p<0.001) and Fe (p<0.058) concentrations increased remarkably within the normal range. The 8-week resistance exercise tended to induce fiber consumption (p<0.089) of subject students and changed the P/M/S ratio changed into the desirable way from 0.8 : 1 : 1 to 1 : 1 : 1, and that of n-6/n-3 PUPA from 11 : 1 to 6 : 1. After taking exercise, the intake frequency of cookies (p<0.058) and raymeun (p<0.085) decreased, but finally this feeding pattern returned to the way as before even though at marginal significance. Consequently the resistance exercise may induce the desirable changes of body fat and improve serum lipid profiles and feeding patterns in young obese females.

  • The purpose of this study was to evaluate the effect of a nutrition education program on 42 obese young adolescent girls. Nutrition education was performed for six months including both group and individual programs, and was focused on improving their eating habits and food composition. The topics discussed once a week included : eating habits, lifestyle management, 5 basic food groups, snack and fast-food, how to eliminate empty calories, fat and hyperlipidemia, food diary, benefits and methods of exercise, vitamin and minerals, evaluation of fad diets, yo-yo effects and so on. The effects of the nutrition education program were evaluated for nutrition education and exercise regimen group (NE+E), nutrition education only group(NE), and control group(C). NE+E group had additional exercise programs 3times each week, while NE group was educated about exercise only by a nutrition education program. In both NE+E and NE groups, there was a significant decrease in bodyfat compared to C group, but NE+E group had a greater change than NE group(5.5% vs 3.1%). In addition, serum triglycerides decreased about 40mg/dl and total cholesterol 20mg/dl in both NE+E and NE groups. But HDL-C level was increased only in NE+E group. The greater changes in body fat and blood lipid levels occurred between the pre- and mid terms fo the education regimen. They kept their changed measurement throughout the 6 months follow-up studies. The results of this study show that this nutrition education program is helpful for obese adolescent girls in decreasing body fat and serum lipid levels. Also, the combination of an exercise regimen with the nutrition education proved to be more effective.

  • Ijidang(二止堂) is a private village school (seodang, 書堂) established in Okcheon, north Chungcheong province where Jungbong Jo, Heon(重峯 趙憲, 1544-1592 AD) had trained for his sound mind and body(yusangcheo, 遊賞處). Jo, Heon was a notable Neo-Confucian scholar of the Kiho School and also a righteous general leading soldiers in Joseon Dynasty. According to Ijidanggi(二止堂記), Ijidang was constructed to honor Jo, Heon and to train local talents in 1647 with the support of Song, Si-yeol(宋時烈, 1607-1689 AD),a representative scholar belong to Kiho School and other local Confucian scholars. Ijidang currently consists of Main Body(本體) in the middle along with the East(Dong-lu 東樓) and the West Pavilions(Seo-lu 西樓) attached to each side. The Main Body and the Dong-lu firstly constructed were to give lectures and to rest within. Ijidang has undergone several changes in its form so far. The surrounding nearby Ijidang shows characteristics of the Confucian architecture for training(J eong-sa, 精舍) and the building itself was to be built in a scenic place apart from the secular world in which scholars stayed, cultivated their body and mind or taught disciples within. The lecture space of Ijidang is positioned next to the main hall(Dae-cheong 大廳) unlike other typical forms of a three-bay building(samganjije 三間之制) at that period. West lu, a two-story building added afterwards in the early 18th century representing characteristics of the Gate Pavilion(Mullu, 門樓) of Neo-Confucian Academies(Seo-won, 書院) in Joseon Dynasty was typically located where the entrance and the ground floor of the main building are visible simultaneously.

  • Effects of microstructure of two Mg-ferrite specimens with the same starting composition and relative density but with different grain size on B-H hysteresis loop, natural resonance frequency, and ferromagnetic resonance line width are reported. Such properties as B-H hysteresis loop, saturation magnetization, natural resonance frequency, and ferromagnetic resonance line width were influenced by the microstructure development during sintering. Large grain size specimen showed high saturation magnetization, low coercive force, low natural resonance frequency, and low ferromagnetic resonance line width compared with the specimen of small grain size. The main reason for the changes in properties can be explained by the variation in anisotropic characteristics due to Fe+2 content generated during sintering process.

  • A eight weeks feeding experiment was conducted to investigate the effects of different dietary dimethyl-$\beta$-propiothetin (DMPT) levels on growth and chemical components in red sea bream (Pagrus major). The content of DMPT extracted from Ulva pertusa by auroclaving was 32.5mg%. Body weight gain, feed efficiency and feed intake were significantly increased with dietary DMPT level. After eight weeks of feeding trial, moisture content decreased with supplemented DMPT level, while crude protein and lipid contents increased with dietary DMPT level. Amino acid contents of muscle was elevated in the DMPT added groups compared to control group. Amino acid composition of muscle in fish fed the diets supplemented DMPT was not different to that of control group. Fatty acid contents of muscle in fish increased with dietary DMPT level.

  • The aim of this study is to identify needed consumer education changes through the analysis of the consumer education in elementary schools. The findings of this study are:1. The current situation of elementary school consumer education was examined through analysis of the curricula of elementary schools. 2. Teacher attitudes and perceptions toward elementary school consumer education were also examined. Although the elementary school teachers clearly understood the importance of consumer education, the problem is that a training workshop or program has not been provided for them. This deficiency needs to be addressed quickly. 3. The third part of the study consisted of an analysis of the curriculum of the 11 Teacher’s Colleges in Korea. This partof study revealed that consumer education was not systematically addressed at Teacher’s Colleges. This finding suggests that it is important to have an included with other opening lecture on consumer education, cultural subject. The content of the consumer education must be positively emphasized and applied systematically.

  • The changes of the total body composition, internal organs, skeletal muscles, and epididymal fat pad in rats fed protein depletion diet and 4 different recovery diets were examined. Seventy-eight male Sprague-Dawley rats weighing $212{\pm}2$ gr were used, and the results were as follows : A) After the 2 weeks of protein depletion, body weight decreased about 20% from the initial weight. It was mainey due to the total body lipid reduction. Among various organ weights, liver and spleen reduced $35{\sim}58%$, kidney and heart reduced $18{\sim}30%$, and muscles reduced $2{\sim}13%$, while brain, epididymal fat pad were not changed significantly. In regarding protein and lipid contents of these tissues, protein in liver, lipid in muscle, and both in spleen were markedly reduced. B) With the 2 weeks of feeding recovery diets, the increases of body weight were different among 4 Groups. High-fat group gained at the highest level (67%), and high-CHO group the lowest (30%). Total body composition (%) cf the standard and high-protein groups recovered to the level of 0 day protein depletion, while protein in the high-fat group and water in the high-CHO group decreased, and fat in these 2 groups increased. Weights of organs and muscles of the high-protein and high-fat groups were similar to the standard group and tllose of the high-CHO group were lower than the standard group. Composition of organs and muscle in the high-protein group was similar to the standard group, while the N contents of the high-fat and high-CHO groups were lower an the lipid content of the high-fat group was higher than the standard group. The weight and lipid content of epididymal fat pad were the highest in the high-fat group.
