Three kinds of mangrove oysters, species of high commercial value in tropical regions, were collected in Cocineta Bay, Venezuella in 1976, at the mouth of Hoffman River, Liberia in 1978 and at the West Coast of Benzina, Indonesia in 1984. Crassostrea rhizophorae from Venezuella showed the most round shell form and greatest shell capacity. In addition, the fatness condition of $9.63\%$ topped the ether two species. Crassostrea tulipa inhabiting Liberia had the most elongated shell form. Although shell capacity of this species was almost similar to Crassostrea rhizophorae, it took up intermediate position in fatness condition with $8.15\%$. Crassostrea beleheri from Indonesia. just as rounded as C, rhizophorae, showed the biggest values in total weight and shell weight but the least fatness with $6.62\%$.

This study was performed to investigate the interrelationship between fasting serum insulin, eating behaviour, daily energy intake and the fatness in obese and non-obese women. The possibility of fasting serum insulin as potential predictive factor for eating behaviour and daily energy intake was also investigated. The results are as follows: 1) In obese women ; Subjects with higher fasting serum insulin were associated with higher speed of eating and shorter meal duration time. No association could be found between daily energy intake or the degree of obesity and fasting serum insulin. There was a significant positive correlation between obesity, daily energy intake and speed of eating. Obesity, daily energy intake were negatively related to meal duration time. Subjects with a rapid speed of eating were apt to overeat during eating behaviour experiment. Our findings suggested that a rapid speed of eating is a contributing factor to the development of obesity in obese women. 2) In non-obese women ; While subjects with higher insulin level were apt to overeat, we could not find any relation between overeating and daily energy intake. There was no correlation between eating speed and daily energy intake, but a significant positive correlation was found between meal duration time and daily energy intake. The degree of fatness was increased with the lower daily energy expenditure per body weight, or the higher waist hip girth ratio, fasting serum insulin and daily energy intake.

The seed of Japaness oyster, Crassostrea gigas(Thunberg), cultivated along the southerncoast of Korea have been transplanted and cultivated in both the Seonyu island and the Eocheong island of the western coast of Korea. The present study was carried out to investigate the growth of transplanted oysters, environmental factors influencing their fatness, and differences of two areas between the Seonyu island and the Eocheong island during the period from April to November, 1978. The results obtained were as follows: 1. Maximum height of the shell was 69.2mm (58.4mm on the average) in the island of Seonyu and 64.8mm(53.2mm) in the island of Eocheong, respectively. 2. The fatness of the oysters measured in the island of Seonyu (5.2g/month) was greater than in the island of Eocheong (2.5g/month) 3. The shell height was increased with high temperature while, the shell fatness with low temperature. 4. The growth rate of the transplanted seed oysters was twice as much as that of native ones in the western coast of Korea. 5. Environmental conditions of Seonyu island were more favorable in cultivating oysters than those of the Eocheong island.

The purpose of this study was to investigate the weight control behaviors, the degree of fatness and dance major on behalf of finding the effects of eating disorders. 779 female high school students, 283 dance major students and 496 general major students, were participated in the study. A self-reporting type of questionnaire survey was conducted during the period from $6^{th}$ May to $18^{th}$ April of 2005. Collected data were processed using SPSSW in 12.0; they were analysed through frequencies, percentages, means and standard deviation, and stepwise multiple regression analysis. The results of this study are as follows : 1. With regard to the level of eating disorders(EAT-26), 33.9% of risk group of eating disorder female dance students, and 13.7% of risk group of eating disorder female general major students. Weight-control behaviors in this research were 1) weight control concerns, 2) weight control trial, 3) weight control methods (prescription of M.D., ways of weight control), 4) eating habits. First, 56.6% of subjects had high concerns about weight control, and 92% of subjects had tried weight control. Second, only 5.1% of subjects were prescribed by M.D. Third, subjects had been using wrong methods(25.7%) of weigh control such as fasting, using drugs, vomiting, wearing laps etc. Fourth, 42.7% of the subjects had bad eating habits. The degree of fatness was as follows: 1) BMI(Body Mass Index), 2) self report about weight 3) distorted body image. Depending upon the BMI, the subjects with obesity were not found in female dance students; Comparatively, 36.9% of dance students were fat and 1.4% of the students were very fat. In terms of distorted body image, only 14.9% of all subjects were the same between the subjective degree of fatness and the objective degree of fatness. 2. As a result of multiple regression, six variables were found significant($R^2=11.6%$, P < 0.01). Concerns about the weight control significantly influenced on eating disorders(EAT-26). At the same time, major(dance), wrong methods of weight control, distorted body image, prescription of M.D, and eating habits had significantly influenced on eating disorders. This results indicates that the risk of eating disorders among female dancer students was very high. Therefore, professional intervention is needed for female dance students to prevent the eating disorders.

This study was intended to describe women's weight controlling by creating a hypothetic model on the weight adjustment behavior and by examining a cause and effect relationship, and to contribute to countermeasures for practicing their promotion of health and improving the quality of life through creating a predictable model. The subject of study was women who utilize the beauty shop located in Seoul, Busan and Daegu and the study period was 12 weeks from July 10 to September 30 in 2004. Gathered 1093 person's general specialty related with weight adjustment and analyzed covariance to prove the hypothesis using statistics compiled from authentic sources. Also proved coincidence of the hypothetical model. Exogenous variables of the hypothetical model are composed of recognition of her body shape, fatness level, age, stress, and self-respect. Endogenous variables are health- control mind, recognized health state, self-efficacy, intention, and behavior of weight adjustment. There were 5 measured variables for exogenous variable(x). There were 8 measured variable(y) for exogenous variable. And coincidence $x^2=297.38$, standard $x^2(x^2/df)=7.08$, GFI=0.962, AGFI=0.917, NFI=0.875, TLI=0.794, CFI=0.889, RMSEA=0.075. The result of hypothesis had an epoch-making record that 20 out of 27 hypothesis was proved positive way. Generally weight adjustment has been highly seen in housewives, the married and the old age. Health control mind seems to be high as fatness level, age, and self-respect are high and low stress. Recognized health state is high as age and self-respect are high and low stress. However, it is not much related with recognition of her body shape and fatness level. If age, self-respect, health control mind, recognized health state and self-efficacy are high intention of behavior is also high, but intention of behavior has no relation with recognition of her body shape, fatness level and stress. If fatness level, age, self-respect, health control mind, recognized health state and self-efficacy and intention of behavior are high, execution of weight adjustment will be high. However, recognized health state and stress has no influence for weight adjustment. To increase the coincidence of hypothesis and take a simple model I modified a model and then I got the coincidence $x^2=215.62$, standard $x^2(x^2/df)=6.34$, GFI=0.970, AGFI=0.931, NFI=0.902, TLI=0.901, CFI=0.915, RMSEA=0.070. This result is a bit better than original hypothetical model's so that this model might be more suitable. In this modification model, the factors of weight adjustment seems to be high according to this order self-efficacy, recognized health state, age, intention, health control mind, self-respect, fatness level and stress. With this result I suggest ; 1. Enforcement of IR that everybody can be controlled weight adjustment herself and continuous education, which is related with regular habit (food, exercise, restriction of a favorite food and behavior training etc.) is also needed. 2. Because self-efficacy is influenced to execution of weight adjustment specific program which can increase self-efficacy should have to develop and we need to utilize it to take care of herself. 3. To protect fatness and be active weight adjustment the peculiar program including the concept of self-respect, recognized health state, health control mind and intention must be developed and not only women but also all of people should be educated. 4. This hypothetical model is forecasting women's weight adjustment behavior and can be utilized for fundamental data to increase those people's health.

L- arabinose residues are widely distributed in plant cell walls, where they are present in polymers such as arabinans, arabinoxylans, arabinogalactans and arabinogalactan proteins. L-arabinose suppress intestinal sucrase and decrease the adsorption of sugar in the small intestine, consequently, weight loss and fatness prevent. Now, xylose be used replacement sugar and arabinose be utilized fatness prevent of our time. Various Agricultural surplus like com fiber, contain $20\;{\sim}\;40%$ of hemicellulose. Corn fiber from Agricultural Renewable Biomass was chosen the best suitable material for arabinose production. In this work, we searched about for L-arabinose gene in compost, metagenome pool and indonesian soil. So, the B1029 TS2-8 of L-arabinase gene in compost was selected by YNB media(5% yeast nitrogen base, 5% arabinogalactan). After enzyme reaction with corn fiver, B1029 TS2-8 produced 2.15 g/L of L-arabonose.

We examined the dB difference in target strength at multiple frequencies (ΔTS) for the identification of Antarctic krill (Euphausia superba) and ice krill (Euphausia crystallorophias) using a stochastic distorted-wave Born approximation model. Our investigation focused on ΔTS patterns at multiple frequencies in relation to size, along with key acoustic properties influencing TS, including density and sound speed contrast, fatness, and orientation. The findings revealed that the orientation and fatness significantly affect the ΔTS patterns. The results provide insight into the importance of the multi-frequency technique for estimating krill biomass and their ecological interactions with environmental features in the Southern Ocean.

The peroxisome proliferator-activated receptors (PPARs) are members of a superfamily of nuclear hormone receptors. Lots of studies in rodents and humans have shown that PPARs were involved in lipid metabolism and adipocyte differentiation. The main objective of this work was to detect the single nucleotide polymorphisms (SNPs) in whole coding regions of peroxisome proliferator-activated receptor alpha (PPAR-$\alpha$) and gamma (PPAR-$\gamma$) genes with approach of single strand conformation polymorphism (SSCP) in the chicken population of Arber Acres broiler, Hyline layer and three Chinese native breeds (Shiqiza, Beijing You, Bai'r). Two SNPs of C1029T and C297T were found in chicken PPAR-$\alpha$ and PPAR-$\gamma$ genes respectively and each SNP found three genotypes in the experimental populations. The results showed that the distribution frequency of 3 genotypes in Arber Acres broiler, Hyline layer and Chinese native breeds had significant differences on the PPAR-$\alpha$ and PPAR-$\gamma$ gene respectively (p<0.01). Furthermore, in the PPAR-$\alpha$ gene, the results of least square estimation for genotypes and body composition traits showed the BB genotype birds had higher abdominal fat weight (AFW) and percentage of abdominal fat (AFP) than AA genotype birds (p<0.05). From these we conjecture the PPAR-$\alpha$ and PPAR-$\gamma$ genes were suffered intensive selection during the long term commercial breeding and the PPAR-$\alpha$ gene may be a major gene or linked to the major genes that impact chicken fat metabolism and the SNPs could be used in molecular assistant selection (MAS) as a genetic marker for the chicken fatness traits.

Purpose: The purpose of this study was to investigate the effects of a walking and resistance exercise on body composition and lipid profile in obese women. Methods: Fourty three women were assigned to experimental group (n=21) or control group (n=22). The walking and resistance exercise using elastic band was provided three times a week for 12 weeks. Weight, height, body mass index, body fat percentage, abdominal fatness, skeletal muscle mass, body fatness, total cholesterol, triglyceride, HDL cholesterol, and LDL cholesterol were measured before and after the program. Paired and independent t-tests were performed using SAS program. Results: Weight (t=-5.35, p<.001), body mass index (t=-4.12, p<.001), body fat percentage (t=-2.33, p =.026), and body fatness (t=-4.32, p<.001) were significantly decreased and skeletal muscle mass (t=2.09, p =.044) was significantly increased after the walking and resistance exercise. Also, total cholesterol (t=-3.03, p =.006) and LDL cholesterol (t=-2.70, p =.011) were significantly decreased and HDL cholesterol (t=2.05, p =.046) was significantly increased after the exercise program. Conclusion: According to the study result, exercise led a positive outcome on obese women in their 30~40s. The walking and resistance exercise will contribute to the improving body composition and lipid profile in this population.

The prevalence of obesity and its related factors in adolescent girls in Seoul area were investigated from April, 18 to June, 29 1985 bymeans of anthropometry, dietary intakes and general environmental factors. Nine hundred and sixty junior high school girls were selected and invterviewed for 24-hour food intakes. Weight, height, a 우 skinfold thickness(triceps, abdominal) were measured and information on the general backgroun of the subjects were obtained by questinnaire. Subjects were divided into six groups according to their relative weights. It was observed that majority of the parents were under fifty years old and had high school education . In general, father was older and higher in educational levels than mother. Two thirds of subjects lived in their own houses and had three to four siblings. AVerage weight and height of subjects were 46.0kg and 154.4cm, which were higher than Korean natianl average. Average relative weight was 29.75 and average Kaup index was 1.925. Skinfold thickness was 13.4mm fo rtricepts and 16.4mm for abdominal . Prevalence of obesity was 12.9% and 4.8% by criteria of relative weight and skinfold thickness. Average intakes of most of nutrients except iron were acceptable but about one third of the subjects had less than 2/3 of RDa for calcium, iron, vitamin A, and riboflavin. As a whole, prevalence of obesity in this study was higher than those observed in the past surveys. Relationship of dietary intakes and general environmental factors that seemed to influence the obesity were integrated as such. As parents educational levels were higher, it tended to be higher in living standard and have fewer family members and siblings. These may influence more nutrient intakes so that fatness of the subjects seemed to be greater. In the meantime, parents fatness was closely related to those of children indicating an involvement of genetic factors. And also, food habits of individuals such as frequency of snack and bedtime snack were related to fatness significantly.
