Many arthritis patients experience weakness of muscles in extremities mainly due to disuse atrophy and weight gain because of the limited activities and exercises. This study examines the effects of the 6-week aquatic-exercise program on the body fat and the muscle of the rheumatoid arthritis patients. Seventeen patients in the experimental group and 18 in the control group were assigned depending on their preference and physical condition. These patients had more than 3 points of pain out of 10, deformities in knee, wrist and ankle joints. The amount of aquatic exercise increases from 35 minutes in the first week to 60 minutes in the 6th week. In the resting period they discussed their own experiences about exercise, personal and family affairs, and performed some recreation programs in order to increase the self-efficacy and promote the relationship with other patients by the group activities. Skinfold thickness and circumferences of both extremities were measured before and after experiment to compare the difference. For testing the body fat Saham Model was used. Prior to the experiment two group's body weight, skinfold thickness and skin circumferences were not significantly different which indicates the homogeneity of two groups. Body weight and most parts of skinfold thickness of the experimental group were significantly lower than the control group after 6-week aquatic exercise program. Circumference was not significantly lower than the control after the program. These findings indicate the in-crease of muscle sizes and the reduction of the body fat. Therefore a more active application of aquatic exercise into a variety of clients is strongly suggested.

The purpose of this study was to inform teachers or researchers relating teaching boys and girls of basic data for valid obesity education. The researcher collected 10 students(5 boys and 5 girls) and measured skinfold thickness and body-fat-percentile(% body fat) on 3 parts of the body every month during a year. The researcher checked the spring(March), summer(July), autumn(October) and winter(January) data consecutively and tried to answer the question that which season especially need the preventive education of obesity. The result as followed ; 1. The skinfold and BFP in summer were more bigger than those in winter but these differences were not significant. 2. Girls have a propensity to get higher skinfold and BFP than boys but these differences were not significant neither. Briefly speaking, in 12 months, the skinfold and BFP(compared in summer) in winter season has the highest and it showed that it was necessary to teach students to preserve their appropriate body fat through diverse activities. The researcher expects successive studies for much more students and by type of students are executed for supporting these results.

This study was to decided the proper garment pressure level on the human body parts. Six volunteers (female: 30-40years) put on the same types of bands, a brief, and a non-woven gown. Garment pressure was measured in regular order with the elastic band on the human body parts such as the upper arm, the waist, the thigh, and the calf. At the same time, physiological responses such as the skin blood flow rate on 2 fingers, 7 different skin temperatures, rectal temperature, heat rates, and subjective responses about the pressure sensation, thermal sensation, and humidity sensation were measured and inquired. The results were as follows; 1. The thicker subcutaneous fat thickness, the higher the mean garment pressure on pressurizing the upper arm(p<.001). Also the thicker subcutaneous fat thickness. the thicker the upper arm circumference. 2. Heart rates increased pressured the upper arm and decreased pressured the waist, the thigh, and the calf. The higher the garment pressure, the higher heart rates on all body parts were pressured. Especially lean subjects showed higher physiological load than others. 3. On pressurizing the upper arm, heart rates, rectal temperature, and mean skin temperature were higher than without pressured state and pressured other body parts.4. The proper garment pressure levels were decided 30gf/$cm^2$ for fat people, 20gf/$cm^2$ for others on the upper arms and 24gf/$cm^2$ on the calf.

The study of candidate genes is an important tool to identify genes associated with economic traits. Three genes were selected to study the association between polymorphism and economic traits and breed of pigs. Growth hormone releasing hormone (GHRH) takes part in growth metabolism and is one of the candidate genes known to be highly associated with economic traits in pigs. Heart fatty acid-binding protein (H-FABP) is related to back fat thickness and intramuscular fat (IMF) content, and myogenin (MYOG) is associated with the amount of growth rate and lean yield in pigs. By PCR-RFLP analysis, the association between the genotypes of the three genes and the average daily gain, back fat thickness, feed conversion, body length and meat percent in 352 pigs (112 Duroc pigs, 132 Landrace pigs and 108 Yorkshire pigs) were analyzed. GHRH polymorphisms showed differences depending on breed (p<0.01) and were associated with meat percent. H-FABP polymorphisms also showed significant differences among breeds and sex (p<0.01), and were highly associated with average daily gain, feed conversion and back fat thickness (p<0.01) and even showed an association with meat percent (p<0.05). However, the MYOG gene showed no significant effect in this study. These results reconfirmed that GHRH and H-FABP are potential major genes or markers for economic traits.

This study was aimed at evaluating the lipid status of 122 pregnant women, who were attending peripheral community clinics in low-income areas and were vulnerable in terms of public health, by anthropometric measurements, estimating dietary intakes and analyzing serum lipids content and fatty acids composition. Regarding the skinfold thickness, it has increased more significantly in suprailliac than in triceps, biceps, subscapular, which means body fat has been accumulated in central parts more than in distal parts of the pregnants. It is found that intakes of energy, protein, lipid and carbohydrate are desirable while calcium, zinc and copper are low and sodium is excessive. Regarding dietary fat intake, the energy $\%$ of fat was within the same range as RDA(20%) for adults, but energy $\%$ intake from each fatty acid was usually low, especially energy % of monoun-saturated fatty acid intake was below RDA for adult women. And intake ratio of $\omega$6$\omega$3 fatty acids was desirable. Accordingly, it is thought that dietary fat intake was balanced in quality. Serum lipids concentrations were increased with the length of pregnancy and were higher as compared with non-pregnant women. Polyunsaturated fatty acids, especially $\omega$6 fatty acids, have gradually decreased with the length of pregnancy. Serum lipids content and fatty acids composition were not greatly influenced by dietary fat but serum free fatty acid level was negatively related to energy, carbohydrate, fatty acids and cholesterol intake. On the basis of the above results, it can be predicted that lipid metabolism for mother and fetus is changed by pregnant status and multilateral research on maternal nutrition in terms of areas and income levels will have to be made.

The purpose of this paper it to investigate the differences in prevalence of obesity and body fat distribution on the variances of age. Height, weight, skinfold thickness and girth circumference on about 422 women residing in Cheju, Korea were surveyed. The results of analysis of the survey are as follows : 1) All the antropometric measurements except height were shown to increase with age. Weight is at its highest level between the age of 50-59. The measurement of skinfold thickness and girth circumference between the ages of 20-39 of the female subjects are significantly higher than the above 40's. However, there is no significant difference among the middle aged women. 2) Physical indices tend to increase according to age. Both BMI and RBW of women in their 50's are at their highest values, however, the index values of the women in their 60's decreased slightly (p<0.05). On the contrary, there is no significant difference in the percentage of body fat and total body fat content among the middle aged women surveyed. 3) According to this survey, 15.6% of the 422 subjects are assessed as being obese ; more specifically 4.4% of women in their 20's, 12.6% in 30's, 25.6% in 40's, 22.5% in 50's and 17.3% in 60's. 4) 39.4% among obese women proved to be upper body type women. Because the frequency of upper body type women became higher as the obese women aged, there is possibility that the pattern of fat distribution can change. 5) Weight is the most highly correlated with BMI(r=0.91), whereas weight as correlated with RBW, percentage of BF and WHR are 0.8, 0.66 and 0.44 respectfully. The conclusion of this survey is that it is better to estimate the value of total body fat and percentage of body fat than the value of BMI in the analysis of prevalence of obesity and its related factors of middle aged women.

This study was carried out to evaluate the body fat breakdown during topical seaweed extract treatment and in combination with the iontophoresis method to enhance skin absorption of lipolytic compounds. Of 14 female obesity subjects, 7 treated a gel types of seaweed extract only(control group) and 7 treated in combination with the iontophoresis(experimental group). Topical treatment of each sample was designed for 2 weeks, treated with 2 times a day about $10m{\ell}$ on the abdomen, triceps and thigh, respectively. Experimental group treat with the iontophoresis during 5 minutes immediately after topical treatment. After one and two weeks of topical treatment, measured body fat, skinfolds thickness, body circumference respectively. Then venous blood samples were taken and analyzed serum lipids. The results were as follows; 1) There were decrement of body weight, $\%$ of body fat, abdomen, triceps and thigh circumference and abdomen, triceps and thigh thickness between pre and post treatment in both group. These decrement were predominant in the iontophoresis treated group. Especially, there were $16\%$ of body fat decrement in the experimental group after two weeks iontophoresis treatment(control group VS experimental group = $33.54{\pm}2.70$ VS $28.37{\pm}3.38$, p<0.01). 2) There were decrement in total CHOL, LDL, TRIG and increment in HDL in both group. These phenomena were predominant in the iontophoresis treated group. CHOL decrement in the experimental group were significant after two weeks iontophoresis treatment(control group VS experimental group = $190.24{\pm}34.36$ VS $157.76{\pm}24.45$, p<0.001). These results suggest that the topical treatment of seaweed extract effective for fat breakdown and maximized in the combination with the topical seaweed extracts treatment and the iontophoresis.

This study was conducted to investigate the dietary intake, anthropometric data, and association between two factors and main food sources contributing macronutrients for overweight and obese females. Subjects were 85 adult females (overweight : 28, obese 57) where mean age was 38.7y. The results are summarized as follows. Mean fat percent, BMI, obesity rate were 29.3, 23.9 and 15.1%, respectively for overweight women and 32.7, 28.3, 36.4%, respectively for obese women. There were significant differences for most of the anthropometric data between groups. Fat percent for all subjects was significantly correlated with weight, waist circumference, hip circumference, mid arm circumference or skinfold thickness for the triceps, subscapular and suprailiac (p < 0.001). The parameter which showed the highest correlation coefficient (r=0.6156) with fat Percentage was the waist to hip ratio. Any significant differences were not found in dietary intake of nutrients or in diet composition between groups. The mean energy intake was 2090.1kcal (104% of RDA) for overweight women and 2113.0kcal (106% of RDA) for obese women. PFC ratio for overweight was 17 : 24 : 59 and 18 : 23 : 58 for obese subjects, which can be regarded as higher fat and lower carbohydrate percentages compared to recommended PFC ratio (15 20 65) .4) Fat intake was positively correlated (r : 0.2301, p < 0.05) with the triceps skinfold thickness, protein intake was also positively correlated with waist circumference (r=0.2668, p < 0.05) or fat weight(r: 0.2406, p < 0.05) .5) The main food items that contributed to energy intake for overweight or obese subjects were similar (rice, pork, bread, grapes, barley) except com oil in overweight or instant noodle for obese group. The subjects in this study were taking less energy from rice and more energy from pork and bread than women from 98 National Health and Nutrition Survey. Because there were no significant differences of dietary data between overweight and obese group, further investigation considering basal metabolic rate or activity would be needed.

Purpose: Although insulin is usually injected into the abdominal subcutaneous fat, in pregnancy women tend to avoid abdominal injections due to concern about fetal damage. Prior studies have been limited to only measuring skin-subcutaneous fat thickness (S-ScFT) at one site at specific pregnancy points. This study aimed to measure S-ScFT across several abdominal sites and over the gestational period in Korean pregnant women. This can identify which site would be relatively safe for subcutaneous injection during pregnancy. Methods: Healthy women over 24 weeks of pregnancy in Korea were invited to voluntarily participate in this descriptive study. For the 142 women, S-ScFT of 12 sites in the abdomen were measured by ultrasound, several times over the pregnancy. Each incidence was treated as a case and a total of 262 cases were analyzed. Results: The mean S-ScFT during pregnancy was 1.14±0.47 cm (1.25±0.54 cm at 24⁺⁰-27⁺⁶ weeks; 1.17±0.48 cm at 28⁺⁰-31⁺⁶ weeks; 1.09+0.40 cm at 32⁺⁰-35⁺⁶ weeks; and 1.06±0.47 cm at 36⁺⁰-40 weeks of pregnancy). Most S-ScFT were thicker than 10 mm. But S-ScFTs in the lateral abdomen and some sites were suboptimal (<6 mm), especially in the pre-pregnancy underweight body mass index group, who had a high rate of suboptimal thickness (27.1% overall and 33.9% in the lateral side). Conclusion: The whole abdomen seems to be appropriate for subcutaneous injection in most Korean women during pregnancy, with a 4 to 5-mm short needle. However, for the lateral abdomen, making the skin fold might be needed for fetal safety.
