The purposes of this study were 1) to investigate high school girls' overall clothing satisfac-tion and self concepts, 2) to clarify the relationship between clothing satisfaction and self concept in terms of body cathexis, school achievement and social self-esteem, and 3) to find out the social self-esteem differences among the groups related to the high and low levels of clothing satisfaction, body cathexis as well as school achievement. Body Cathexis was measured by the Secord and Jofrard's Body Cathexis Scale. School achievement and social self-esteem were assessed with the modified questionnaires based on the previous researches. Clothing satisfaction which included 3 aspects was measured by the questionnaires developed for this study. The questionnaire was administered to 464 high school students in Seoul, and the data were aiialyzed by frequency, 1-test, one-way·ANOVA and SNK test, Pearson's product moment correlation and factor analysis. The results of this study were as follows: 1) High-school girls 'body' cathexis showed low levels of mean and distribution, wheareas school achievement and social self-esteem showed high levels of those.2) There werf significant positive correlation between clothing satisfaction and all of the self concept variables. In addition, positive correlation were found among the three self concept variables. 3) Three clothing satisfaction factors were emerged and named as clothing possession, clothing selection ability and parent's clothing restriction. Clothing posses- sion and parent's clothing restriction were generally satisfied. 4) School achievement was the most influencial variable for the level of serial self-esteem. It was thought that body dissatisfac-tion would be relieved by the high clothing satisfaction.

Three experiments were conducted with broilers to study the effects of early feed restriction. In all studies, treatments were represented by three replicated floor pens, each containing 20 birds. In Experiment 1, broilers were fed at 0.75 kcal ME/g BW/sup0.67 for 3 d, 1.5kcal m/E BW/sup0.67 for 5 d or 2.25 kcal ME/g BW/sup0.67 for 7 d, all imposed beginning at 7 d of age. Birds were smaller following feed restriction(P<0.05), although growth compensation occurred, and at 49 d all restricted birds were same(P>0.05) to full-fed control buds in body weight. Growth compensation was associated with improved feed conversion(P<0.05), although carcass composition was unchanged. In a second study, all birds were fed at 0.75 kcal ME/g BW/sup0.67 for 3 or 5 d, starting at either 4, 7, or 10 d of age. When feed restriction was applied for shorter periods of time, growth compensation occurred(P>0.05). With more severe feed restriction, birds were smaller(P<0.05) at 49 d compared to control. Feed conversion was improved following prior feed restriction(P<0.05, 4 to 49). In a third trial, broilers were fed a starter diet diluted with 50% rice hulls. Birds failed to consume enough of this diluted feed, and so were initially smaller, However 49 d weight was not affected (P>0.05). When periods of 24 h feed withdrawal were imposed in conjunction with the diluted diets, birds were under weight at 49 d. It is concluded that physical feed restriction at 0.75 to 1.5 kcal ME/g BW$\^$0.67 imposed for 3 to 5 d in the early life currently presents the best option as a means of controlling broiler growth so as to improve feed efficiency.

BACKGROUND/OBJECTIVE: The goal of the present study was to investigate the effects of moderate caloric restriction on ${\beta}$-cell function and insulin sensitivity in middle-aged obese Korean women. SUBJECTS/METHODS: Fifty-seven obese pre-menopausal Korean women participated in a 12-week calorie restriction program. Data on total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglycerides (TG), and fasting serum levels of glucose, insulin, C-peptide, blood pressure, leptin and anthropometrics were collected. A dietary intake assessment was based on three days of food recording. Additionally, ${\beta}$-cell function [homeostasis model assessment of ${\beta}$-cell (HOMA-${\beta}$), insulinogenic index (ISI), C-peptide:glucose ratio, and area under curve insulin/glucose ($AUC_{ins/glu}$)] and insulin sensitivity [homeostasis model assessment for insulin resistance (HOMA-IR), Quantitative insulin-sensitivity check index (QUICKI) and Matsuda index (MI)] were recorded. RESULTS: When calories were reduced by an average of 422 kcal/day for 12 weeks, BMI (-2.7%), body fat mass (-10.2%), and waist circumference (-5%) all decreased significantly (P < 0.05). After calorie restriction, weight, body fat percentage, hip circumference, BP, TC, HDL-C, LDL-C, plasma glucose at fasting, insulin at fasting and 120 min, $AUC_{glu}$ and the insulin area under the curve all decreased significantly (all P < 0.05), while insulin sensitivity (HOMA-IR, QUICKI and Matsuda index) measured by OGTT improved significantly (P < 0.01). CONCLUSIONS: Moderate weight loss due to caloric restriction with reduction in insulin resistance improves glucose tolerance and insulin sensitivity in middle-aged obese women and thereby may help prevent the development of type 2 diabetes mellitus.

The effects of restricting feed [60% of ad libitum (AL) intake] (FR) or water provided from 0900 h to 1600 h, daily) (WR) or both (FWR) from 14 to 42 days of age on heterophil/lymphocyte (H/L) response and performance in broiler chickens under the hot humid tropical conditions were determined. Feed and/or water limitation retarded growth, but had no adverse effect on overall feed conversion ratio and survivability. The trend for total feed and water consumption was similar to body weight pattern with AL>WR>FR>FWR. The nutritional regimens had significant effect on overall water:feed ratios with FR>(AL=WR)>FWR. Restriction of feed and/or water resulted in marked elevation of H/L ratios. As measured by H/L ratios, the effect of adapting to FR dissipated between 16 to 21 days after the onset of feed restriction. The H/L ratios of WR and FWR birds remained elevated throughout the duration of the experiment.

인체가 균형상태에 있지않게 되면 중력으로부터 보상작용은 과도한 에너지소비로 구축을 야기시켜 이차적질병과 외부로부터 가해지는 충격을 흡수하지 못하고 약한 충격에서도 손상을 초래하게 된다. 또한 물리적 외상, 염증이나 감염의 진행으로부터 오는 구조적 불균형은 부적절한 근막의 긴장으로 초래하게 되고 이 긴장은 근육근막의 제한으로 신체에 기묘한 비특이적 반응으로 나타나 피부분절과 일치하지 않고 무관한 것처럼 보이나 통증이나 기능이상을 초래하여 그 인접관절과 근육에 기능적으로 방해가 되어 중력으로부터 정상적인 자세를 유지하지 못하고 신체의 불균형을 초래하게된다. 신체의 어느 한부분의 근육근막 제한은 인체전체의 균형을 파괴하여 골반 왜곡 또는 다리길이가 불일치한 경우도 나타나며 요천추부위에 긴장을 초래하게 되어 기능장애나 유연성이 감소되어 운동제한과 통증이 생기고 외상이 발생하기 쉽다. 1. 인체는 강력한 근막망(powerfull fascial network)의 상호관련된 통합된 전체로 보아야 한다. 2. 근막은 신체구조들의 응집을 방지, 지지해줄 뿐만아니라 외부로부터 충격을 적절히 분산하여 신체적 균형을 유지시킨다. 3. 근막의 장애는 근육긴장과 경축이 생기고 이완되지 않으면 근육결절로 진행하여 동통을 유발한다. 4. 근막장애는 탄력과 단축을 잃게하고 유연성이 없어져 중력으로부터 지지하는 능력이 떨어져 자세의 변화를 가져온다. 5. 국소부위의 근막장애는 중력으로부터 지탱하려는 인접관절과 근육에 영향을 미쳐 인체전체의 자세에 뷸균형을 초래한다. 6. 자세분석은 근육근막장애에 따른 중력의 역학적 변화를 고려하여 평가하여 분석하여야 것이다.

본 실험은 식이 제한 급여에 따른 비만형 당뇨병 환자의 체중 및 혈중 지질량의 변화에 대한 연구의 일환으로 사람의 비만형 당뇨병과 유사한 병리소견을 나타내는 OLETF 횐쥐를 이용하여 자유급식군, 식이 급여량 20% 제한군과 식이 급여량 40% 제한군으로 나누어 12주간 사육한 후 체중과 혈당, 혈청 콜레스테롤 및 중성지질량을 측정하여 식이 제한 급여 에 따른 혈청 지질량의 변화를 관찰하였다. LETO 횐쥐에서 자유급식군은 12주 후 체중이 41% 증가되었으나 식이 급여량 20% 제한군은 22%, 식이 급여량 40% 제한군은 10%의 체중 증가를 나타냈고, OLETF 횐쥐에서 자유급식군은 24%, 식이 급여량 20% 제한군은 10%, 식이 급여량 40% 제한군은 -2%의 체중 증가를 나타냈다. 혈당량은 LETO 흰쥐에서 식이 급여량 20% 제한군은 혈당량이 감소되지 않았으나, 식이 급여량 40% 제한군은 12% 감소되고, OLETF 횐쥐 혈당량은 식이 급여량 20% 제한군은 15%, 식이 급여량 40% 제한군은 20%가 감소되었다. 혈청 중성지질량은 LETO흰쥐에서 식이 급여량 20% 제한군은 24%, 식이 급여량 40% 제한군은 27%가 감소되었고, OLETF 횐쥐에서는 식이 급여량 20% 제한군은 32%, 식이 급여량 40% 제한군은 37% 정도가 각각 감소되었다. 혈청 총 콜레스테롤량은 LETO 횐쥐에서는 자유급식군, 식이 급여량 20% 제한군과 식이 급여량 40% 제한군에서 모두 차이를 나타내지 않았고, OLETF 횐쥐에서는 식이 급여량 20% 제한군은 15%, 식이 급여량 40% 제한군은 23% 정도가 감소되었다. HDL-콜레스테롤량은 LETO 흰쥐에서 식이 급여량 20% 제한군은 34%, 식이 급여량 40% 제한군은 43%가 증가되었다. 이상의 실험결과로서 식이 제한 급여에 의한 체중, 혈당, 혈청 지질량의 변화가 OLETF 횐쥐에서 LETO 횐쥐에서 보다 더 유의한 것으로 나타나서, 식이 제한 급여에 의한 혈청 중성지질량과 혈청 총콜레스테롤 및 HDL-콜레스테롤량의 변화는 당뇨병에서 더 큰 변화가 유발되는 것으로 추측된다.

A mutation in the promoter region of uncoupling protein 3 (UCF3), specifically the -55C longrightarrow T transition, may influence an individual's energy metabolism and body weight. The objective of this study was to investigate the effect of a weight reduction program on endocrine functions and body fat distribution, related to UCP3 promoter genotype. Ninety overweight pre-menopausal female subjects participated in the weight reduction program at Yonsei University Hospital, and were placed on a calorie-restricted diet (300 kcal less than their daily requirements) for 12 weeks. After 12 weeks, all subjects on the program lost approximately 5% of their initial body weights and had lower Body Mass Index (BMI) values. Among the 90 women, 56 had a normal (without mutation) UCP3 genotype, while 34 women had mutations in the promoter region of UCP3. Despite similar weight reductions in both groups, a significantly higher decrease in abdominal adipose tissue was observed in the normal UCP3 genotype group, compared to the group with mutations. In particular, there was a significant reduction of fat at the lumbar 1 (Ll) level in the without-mutation group. Serum levels of total cholesterol, apolipoprotein Al were significantly decreased in the without-mutation group, by 4.4% and 5.7% respectively. Serum levels of hormones were not significantly changed in both groups artier the intervention. However, in the group without the mutations, the leptin level significantly reduced by 23.4% (p<0.001). Serum free fatty acid (FFA) concentration was significantly increased in the group with mutation following the weight reduction program. On the other hand, FFA responses were shown similar increases in both groups. In conclusion, although no difference was found in the magnitude of weight reduction in both groups, there were significant differences in body fat distribution and in endocrine function between the groups.

Metabolic responses to the protein-free, high-carbohydrate diet and subsequent food restriction on the same diet at the level of 50% and 75% has been studied on the adult albino rats. The energy source was either corn starch or sugar. In experiment I, adult male rats weighing $509{\pm}8g$ were divided into two groups 10 rats each. Rats fed on the stock diet served as a control. Rats of restriction group received a protein free diet until they reduced their weight down to 400g and continue on a protein-calorie restriction diet until they reduced their weight down to 300g. In experiment II, 28 adult male rats and the same numbers of female rats weighing $329{\pm}5g$ and $223{\pm}4g$ respectively were divided into four groups, 7 males and females in each. Rats fed on a stock diet were sacrificed at the point when others started a protein free diet. These were served as the control. The protein free group received a protein free diet ad libitum for 4 weeks. The 50% restriction group and 75% restriction group were fed on a protein free diet coupled with food restriction at levels of 50% and 75% respectively for 3 weeks. In the result of this study: 1. The rate of body weight changes was similar between the males and the females. Feeding protein free diet ad lib. initiated a rapid weight lost of approximately 25% and protein free diet coupled with food restriction showed 37-43% reduction of their initial weight. 2. There was no significant differences in the value of the N concentration in liver, spleen, brain and muscle between controls and experimental groups. 3. Rats fed on protein free diet showed 1/10 value of the control in the nitrogen excretion in urine. However female showed less N excretion than male. 4. Observing blood picture, the effects of protein depletion and calorie restriction were not appeared any remarkable changes. 5. There was no sign of fatty liver which might result from protein depletion and calorie restriction. 6. Following semi-starvation, FAO and HMP-DH total enzyme activity was reduced, but activity per unit weight was relatively stable.

Previously, we used a rigid bronchoscope in removal of endotracheal granulation tissue and foreign body. But these method has poor visual field and difficulty in handling of the instruments, therefore there were restriction in removing the endotracheal granulation tissue and foreign body. Recently we underwent one case each of endotracheal granulation tissue and foreign body causing dyspnea and removed them by right angled forceps under visualization via nasal rigid endoscope inserted through the tracheal stoma. We suggest this method for removal of tracheal foreign body, granulation tissue and excision of tumorous condition in patients with tracheocutaneous fistula.

Objective: This study was conducted to investigate the effects of probiotic, prebiotic and synbiotic with and without feed restriction on broilers performance, blood parameters, carcass characteristics, and feed cost of production from 1 to 56 days of age. Methods: Two hundred and forty unsexed one day-old chicks of Arbor Acres breed were used. Two trials, I and II, were conducted, with 120 birds in both. Each trial was divided into 4 equal groups. The birds in trial I were fed ad libitum throughout the experiment, while the chicks in trial II were fed ad libitum during the first week of age, then subjected to 5 hours/d of feed restriction from the beginning of the second week up to the end of the experiment. In both trials, the birds in group 1 were fed on a control diet while the other groups were given the same control diet supplemented either with a probiotic in group 2, prebiotic in group 3, or synbiotic in group 4. Results: It was found that chicks fed diets supplemented with probiotic, prebiotic and synbiotic (with and without feed restriction) exhibited higher body weight and feed efficiency than chicks fed the control diets. The feed additives in both trials did not affect hemoglobin, serum total protein, albumin, globulin, glucose, and total cholesterol, except the packed cell volume which was increased in the additive treatments with restriction at the end of the experiment. Moreover, the dietary treatments did not influence the carcass yield. However, the relative weights of liver, gizzard and proventriculus, small intestine and bursa of fabricius were found to be increased. The additives decreased the visible fat in the carcass, with more decreasing effect in the additive groups with restriction. The lowest feed cost per kg of weight gain was observed in the birds fed diets supplemented with synbiotic, probiotic and prebiotic. Feed restriction improved the feed conversion ratio, economic return, but decreased the feed intake, serum total cholesterol and visible fat in comparison with non-restricted groups. Conclusion: The biological feed additives could be routinely added to broiler diets, especially when a feed restriction program is followed. Finally, it can be recommended to restrict feed, and add probiotic or synbiotic to increase weight, improve feed conversion rate and reduce feed cost of production.
