Thirty six female students participated in the experiment of the fat mass weight loss. they kept diary for foods they ate every day, took a picture of the foods, transmitted the picture to the experimenter by the camera phone, and consulted him about fat mass loss once a week for 8 weeks period. Fat mass weight and its related factors of the students had been measured repeatedly every week during 8 weeks, The repeated measurement data were used for applying various random coefficient models. And hence optimal random coefficient model was selected. From the optimal model, the baseline, body mass index, diastolic blood pressure, total cholesterol and time of the fixed factors were very significant. The fixed quadratic time effect existed. The variance components corresponding to the subject effect, linear time effect of the random coefficients were all positive. Thus random coefficients up to the linear terms were considered as the optimal model. The treatment effect reduced the weight loss to an average of 2.1kg at the end of the period.

The Clinical Study on the Body Weight Loss of Taeumin Inpatients in Stroke by Sasang Constitutional Medicinal Treatment. Purpose: It has been frequently noted that overweight and obesity have a stronger relationship to hypertension and diabetes mellitus than to the risk of stroke. The purpose of this study is to find out whether Sasang Constitutional Medicinal treatment in the stroke patients of Tae-um-in has an effect on local or general weight loss. Methods: Case-control study was applied. The experiment group is the 24 Taeumin stroke inpatients who were in hospital in Kyung-Hee Oriental Hospital from July 1, 2000 to October 1 and received Sasang Constitutional Medicinal treatment. The control group is the 13 Taeumin stroke inpatients who were in the hospital during the same period but didn't receive Sasang Constitutional Medicinal treatment. In the two groups, body weight, BMI, the skin fold(cm) of triceps, suprailiac, abdominal portion, and thigh and the circumference(cm) of wrist, biceps, triceps, and W/H ratio were compared and studied for three weeks. Results: 1. In the experiment group, there were 8 women and 15 men, 23 in total and in the control group, there were 5 women and 9 men, 14 in total. 2. From two weeks later, there was a significant decrease in the experiment group in weight loss, the ratio of loss, and BMI(p<0.05). 3. Concerned with the change in the skin fold of suprailiac portion, there was a significant decrease in each group(p<0.05). 4. Concerned with the change in the skin fold of Chunchu-Hyel portion(天樞穴), thigh and in the circumference of hip, W/H ratio, there was a significant decrease in the experiment group(p<0.05). 5. Concerned with the change in the value of Lipid Profile, GOT, and GPT, only Glucose(GLU) showed a significant decrease(p<0.05) in the experiment group(p<0.05). As Conclusion, Sasang Constitutional Medicinal treatment in the stroke patients of Tae-um-in has an effect on local or general weight loss.

Postharvest treatments such as polyethylene film wrapping, ethylene scrubber, and fruit coatings were compared to find a potential effect on the fruit quality in 'Fuji' apples during storage and simulated marketing. Polyethylene film wrapping appeared to be excellent in preventing weight loss during storage but fruits lost weight at a high rate when exposed to ambient temperature during simulated marketing. Also, surface cracking disorder was observed in parts of film-wrapped fruit under marketing condition after storage of 21 weeks. Ethylene scrubber effectively removed ethylene in polyetheylene bags but this effect reduced along with the increase of storage time. Although Prolong-treated fruits were good in appearance at 12-week storage, no beneficial effect was found on the inhibition of weight loss during storage as well as marketing. In addition, wax-like substances were accumulated on the surface after storage of 21 weeks, resulting in the reduction of marketability. Water soluble wax seemed highly effective on the inhibition of weight loss during storage and marketing. However, parts of fruit were severely injured probably due to the high concentration of wax. Undamaged fruit showed excellent appearance in shape and flesh quality even after 21 weeks of storage. Further study is required to find the proper concentration of wax.

Topical fluoride application for children is a widely performed procedure in the field of Pediatric Dentistry for its dental caries prevention effects. However, it is recently recognized as having some unwanted effects on several esthetic restorative materials as it roughens the surfaces of the restorative materials. In order to evaluate the surface changes in esthetic restorative materials, the author immersed composite resin, glass ionomer cement, and resin-modified glass ionomer cement specimens in various topical fluoride agents and measured the weight loss and also, examined the specimens under the scanning electron microscope. The followings are the results : 1. All the specimens immersed in APF gel for 4 minutes showed statistically significant weight loss. (paired t-test, P<0.05). 2. There was no statistically significant weight loss for the resin-modified glass ionomer cement and composite resin groups immersed in sodium fluoride solution (paired t-test, P>0.05). 3. When the glass ionomer cement group was immersed in APF gel for 1 and 4 minutes, there was a statistically significant weight loss compare to other esthetic restorative materials (ANOVA, P<0.05). 4. In the resin-modified glass ionomer cement group and the composite resin group, weight loss in the APF gel 4 minutes immersion group was greater than the 1 minute immersion group, and it was statistically significant (ANOVA, P<0.05). 5. When the specimens were examined under scanning electron microscope, the surface changes were greatest in the order of glass ionomer cement, resin-modified glass ionomer cement, composite resin and also in the order of APF gel 4 minute immersion group, 1 minute immersion group, sodium fluoride immersion group, and control group.

A total of 240 crossbred(Landrace ${\times}$ Yorkshire ${\times}$ Duroc) pigs were housed from 70 kg live weight and slaughtered at weights of 95, 105, 115 and 125 kg. The left side loins of carcass were obtained at 24 hr postmortem to measure pork quality. There were significant differences(p<0.01) in eye muscle area of pork loins between the slaughter weights of 95 and 105 kg. However, no differences were observed in pork than 105 kg of slaughter weight. Ultimate pH values were decreased with increasing slaughter weight and cooking loss was also reduced(p<0.01) at the heavier weights. Slaughter weights did not affect the shear force and intramuscular fat. However, dry matter(DM) and crude protein(CP) contents of loin were increased, and cooking loss and sarcomere length were decreased with increasing slaughter weight. The lightness(L$^{*}$) and redness(a$^{*}$) of pork loin were increased with increasing slaughter weight. Results suggested that pork quality may be improved when pig slaughter weight is increased from 95 to 125 kg.

This paper aims to probe the effect of Rosa rugosa, Thunbergii which streptozotocin induced hyperglycemic rats was examined by glucose contents, body weight, kidney weight and histological observation. The results obtained were as follows: 1. The glucose level is decreased in the adminstered group of the Rosa rugosa compared with control group. These effects are in order named root group, stem group and leaf group group. BUN is increased fold of 1.52 in the control group compared with normal group, but the administered group of Rosa rugosa are decreased., in order named leaf group, root group and stem group. 2. The kidney hypertrophy to body weight is the higest in the control group compared with the other group in rats, and glucose contents are in order named stem group, leaf group and root group. 3. The loss of body weight is the highest in the control group, and the loss is in order named stem group, leaf group and root group in rats. 4. In histological observations, pancreatic pancreatic islets of control group shows disrupted or condensed nuclei, and the intercellular space between acini are enlarged. In the experimental group, histological damages of the acini and pancreatic islet are recovered compared with control group. Thes results suggest that the extracts of Rosa rugosa are effected to diabetes mellitus, root extract correlated with the function of kidney, and leaf extract is decreased plasma glucose.

Salmon oil (SO) could be used as a great source of ω-3 fatty acids in pig diet. The purpose of the study was to investigate the SO effect on production performance of sows and their offspring. 48 lactating sows (Landrace × Yorkshire) from Dankook University experimental farm were used in this study. Sows were conceived using either guided natural mating or by artificial insemination. Pregnancy diagnosis was confirmed by ultrasonography on day 25 after mating. Sows and their offspring were assigned randomly to 1 of 2 treatments. Treatments included: 1), control (CON); 2), control + SO 0.5% (CS). The inclusion of SO did not affect (p > 0.05) the litter size throughout the experiment. No difference (p > 0.05) was observed on the average daily feed intake (ADFI), chest circumference, estrus interval and sow backfat thickness between CON and SO treatments. Dietary SO supplemented diet reduced (p < 0.05) body weight loss during lactation compared with control treatment. Pigs fed SO supplemented diet did not affect (p > 0.05) the fecal scores during lactation compared with those fed control treatments. Sows fed SO supplemented diet led to a higher (p < 0.05) initial weight, weaning weight and average daily gain of piglets than those fed control diets. No difference (p > 0.05) was observed on piglet survival and fecal scores throughout the experiment. Inclusion of SO could reduce the body weight loss of sows and improves piglet growth during lactation, indicating SO has beneficial effects for pigs.

Objectives: The purpose of this study was to determine whether gocho (苦椒) extract mesotherapy can effectively reduce weight and abdominal fat in obese patients. Methods: Forty obese participants were recruited and randomly assigned to two groups. Five participants dropped out voluntarily during the course of the study and four men were excluded from the analysis to avoid gender bias. Results are presented on a total of thirty-one women. Over an eight-week period, the treatment group (n=13) received gocho (苦椒) extract injections (100mcg/3cc) in the abdominal skin, twice per week; the control group (n=18) received normal saline injections (3cc). A mixed lidocaine and prilocaine cream (2.5%/2.5% EMLA cream) was applied before the injection. At baseline and 8 weeks, body weight, body-mass index (BMI), waist circumference (WC), waist-hip ratio (WHR), abdominal fat, energy expenditure, and questionnaires (eating attitudes and physical activity) were evaluated in both groups. Results: Reductions in body weight (p<0.005), BMI, and WC (p<0.05) were greater in the treatment group. WHR, total fat area, and visceral fat area decreased only in the treatment group (p<0.05). Resting metabolic rate (RMR) change was correlated with weight loss only in the control group (r=-0.498, p<0.05). Before and after the treatment, there were no significant differences between the two groups in questionnaire variables (p>0.05). Conclusion: his study suggests that abdominal gocho (苦椒) extract mesotherapy might be an effective way to promote weight and abdominal fat loss in obese Korean women.

Objectives: The aim of study was to investigate the effect of herbal medicine on obesity and to define which seasonal factor could be utilized to make an obesity treatment program more effective. Methods: Three hundred and forty-four subjects were recruited and data were analyzed for weight, body fat, muscular volume, body fat ratio, body mass index (BMI) change and treatment duration. At first, age classification was performed for the comparisons. Moreover, starting season of treatment was categorized to determine it's influence over the treatment. Results: It was found the administration of herbal medicine could diminish every analyzed fields of entire patients. Compared among age groups, there were no significant differences of all fields. However, the categorization of start season showed significant differences of weight, BMI change and treatment duration. In addition, the analysis of assumed 10% weight loss elicited patients started treatment in spring and winter should spend 12 and 13 weeks and summer would be 9.5 weeks. Conclusions: It was found herbal medicine would be effective for female obesity and expected patients could achieve 5.91 kg weight loss for 65.88 days treatment. Summer group had significant shorter treatment duration and it was presumed summer group had more concentration for achievement. Days required for assumed 10% weight loss was calculated to be 84 days in spring, 67 days in summer, 96 days in winter. Hereafter, further controlled study with more numbers of patients should be needed to determine the goal of medical treatment for obesity.

This study was carried out for the optimum predegumming in the protease degumming process of silk fabrics by ocmparing the physical properties of silk fabrics degummed with different weight losses of predegumming. 1. In twill habutai, the stiffness of fabric was reduced and the smoothness was improved with increasing weight loss of predegmming, however, the soft feeling value which means the total handle value of medium fabric for lady, was maximum at 20% of predegumming weight loss. 2. In the case of crepe de chine representing thin fabric for lady, the anti-drape stiffness was relatively increased with 22% weight loss of predegumming. However, the other physical properties, such as the flexibility with soft feeling were less related to the degrees of predegumming.
