This study was performed to obtain the basic data which could be used for the modification of the manual center-burner-type rice-husk furnace into a small scale automatic type for the multi-purpose use in the farm. For this purpose, first, the utilization feasibility of the rice-husk furnace in the farm was analyzed briefly in aspects of available amount of rice-husk for the fuel, annual operation time and replaceble amount of residential heating energy with rice-husk in the farm. For the experiment a prototype furnace geared with an automatic feeding device was fabricated, and feed rate, mold size and chimney height were changed to investigate the combustion efficiency of rice-husk and thermal efficiency of the furnace. Also, optimum and limiting operational factors were observed in each treatments. The results obtained are summarized as follows. 1. If the rice-husk is intensively used for residential heating in the farm for winter season, on an average 51 percent of the total heating energy can be replaced with the rice-husk. Therefore, development of a small scale automatic rice-husk furnace was recognized to be feasible. 2. The operational condition depending on husk-feed rates was very important factor for successive steady burning operation of the given furnace. When the feed-rate was 1.5 kg/hr, the top of the burning zone should be kept at the position about 55 cm from the bottom of the combustion chamber with the periodic removal of ash (termed as steady state position), which was 18 cm above the mold waist. When the feed rates were 2.4 kg/hr and 3.0 kg/hr, the steady state position was at about 4 cm above the mold waist. 3. The mold size affected inflow rate of air into the furnace and consequently CO content in the exhaust gas. The relatively bigger mold gave positive effect on the air-inflow rate. 4. When the husk-feed rates were 1.5 kg/hr, 2.4 kg/hr, 3.0 kg/hr, the combustion efficiencies of the rice-husk were 98.5%, 97.4% and 95.0%, the thermal efficiencies of the furnace were 93.4%, 93.2% and 87.6%, and CO content in the exhaust gas were 1.21%, 1.03%, and 2.43%, respectively. The air-inflow rates were decreased with the increase of feed rates. When the amount of excess air was 30-40%, the CO content in the exhaust gas was at the minimum level. 5. When the chimney height was lowered from 260 cm to 96 cm, the air-inflow rate was slightly decreased, but the average temperature in the combustion chamber, CO content in the exhaust gas and combustion and thermal efficiencies were not changed significantly. 6. The incidental problems associated with the protytype furnace were accumulation of the ash inside the mold, accumulation of the cinder between the outer-drum of the furnace and the combustion chamber wall, and accumulation of the cinder in the chimney.

Housewives' perception on obesity related variables to their family members according to the composition of children in the family was explored. Ninety housewives responded to a questionnaire consisted of sociodemographic informations, body weight perception, eating behaviors perception, and physical activity level for herself as well as her family. They were categorized into three groups based on child composition of the family; boys only (BO), girls only (GO), and boys and girls (BG) families. Boys in BO showed higher value of height, weight, and WHR than girls in GO (p <.05), while no differences were noticed in BMI and the waist girth between the groups. Mothers of BO perceived boys were active while mother of GO did girls were inactive (p <.05). Girls in GO ate meals less regularly than boys in BO and girls in BG. In general, housewives' perception on body weight of family members was relied on BMI and waist girth. As mother's BMI increased, the boy's BMI in BO was also elevated (p <.05), but not in others. Mothers' perception on caloric intake and activity encouragement were not accounted for morphological characteristics. Results suggest that housewives perceived obesity related variables differently based on the composition of children of the family.

The purpose of this study was to compare weight control behaviour, eating habits and health-related life habits according to the obesity degree by body fat percentage (%Fat) among middle-aged women. The subjects were 170 middle-aged women who lived Gunsan City, and they were assigned to one of the following groups based on their %Fat; normal weight group (18% - < 28%), overweight group (28% - < 33%) and obesity group (over 33%). The height, body weight, %Fat, the circumference of waist and hip of them were measured. Eating habits and health-related life habits were evaluated based on questionnaires. The results were as follows. Their weight, %Fat, body mass index (BMI), relative body weight (RBW), waist, hip, and waist-hip ratio (WHR) were significantly higher in the obesity subjects when compared to the normal and overweight subjects. Self-perception for weight (p < 0.001), desire for weight control (p < 0.01), and reasons of weight control (p < 0.05) were different among three groups. The main skipped meal was breakfast (67.9%), reasons of skipping meals were different among three groups (p < 0.05), and main reasons were "lose one's appetite" and "have not enough time". Food habits score for each food was not significantly different among three groups, but eating the meal on thinking with food combination in normal group was higher than overweight and obesity group (p < 0.01). Correlation coefficients of food habits score and anthropometric measurements were that salty of food was negative and food habits scores were positive correlation for anthropometric measurements and obesity index (p < 0.05 - p < 0.001). Frequency of exercise and fitting exercise for body were different among three groups (p < 0.05). Obesity group was lower frequency of exercise than the other groups. Regular diet was positive correlation with food combination (p < 0.01), taking fish (p < 0.05), taking vegetables (p < 0.01), taking bean products (p < 0.01) and food habits score (p < 0.01), frequency of eating out and snacks were negative correlation with taking fruits and fishes. Therefore, proper nutritional education for middle-aged women in obesity group is recommended regular diet, good food habits and exercise. The middle-aged women must decrease the frequency of eating out, snack and the salty foods, and increase the fruits and vegetables. They must have healthy life styles for exercise, smoking, and drinking.

Gallstone composition has changed over the past decades in the Korean with a prominent increase in the prevalence of cholesterol gallstone. This trend is possibly due to the westernization of dietary habits. The purpose of this study was descriptive of GB patient's health related eating behaviors and nutrient consumption patterns. One hundred and six gallstone patients who have had cholecystitis surgery enrolled in this study. Anthropomertic indices, such as height, weight, waist circumference, and hip circumference were measured and calculated BMI and WHR. As the biomarker, TC, TG, LDL-C, HDL-C, FBG level and SBP/DBP were measured and analyzed the relationship with GB stone formation. The structured checklist of health related eating behavior and the semiquantitative food frequency questionnaire after pre-test was used in the face to face interview study. The mean age was $54.9{\pm}13.3$ and gallstone disease was more frequent in the fifties and sixties. Mean BMI was $24.3{\pm}2.8$ in males, and $23.4{\pm}3.9$ in females, the average of waist circumference was $91.1{\pm}7.0cm$ in males and females were $85.4{\pm}9.6cm$. The WHR of men and women was $0.93{\pm}0.0,\;0.90{\pm}0.1$, respectively. The obesity and overweight trend was observed in gallstone patients. The mean blood sugar was researched at $114.5{\pm}35.0mg/dL$. And the ratio of both symptoms DM and gallstone was 26.4%. The rate of dramatic eating repast was significantly higher in the females (p<0.01). Males tended to more frequently consume meat, of high fat content meats and greasy food consumption when eating out. The CPF ratio was 57:16.5:26.5. There was a significant positive correlation between WC and energy (r=0.252, p<0.05), carbohydrate (r=0.255, p<0.05) and niacin (r=0.227, p<0.05). In addition, carbohydrate were significantly correlatied with TC (r=0.230, p<0.05). BMI appeared positive in correlation of protein (r=0.201, p<0.05) and fat (r=0.205, p<0.05). These findings provide a little association that dietary habits are related with cholesterol gallstone formation.

This study was carried out to investigate the nutrients intakes of hypertensive female farmers in Korea. The number of subjects in this survey was 40(normal 22, hypertensive 18). Body weight, height, circumferences of waist, hip and thigh, and systolic and diastolic blood pressure of them were measured, and lipids and mineral levels of venous blood, mineral contents of 24-hour urine and Na or K levels of some sodium sources were analyzed. The evaluation of nutritional status was performed by recording dietary intake for a day and analyzing it with food composition table. Body weight, waist circumference, waist to thigh ratio, and serum triglyceride were higher in hypertensive. The mean values of calcium, vitamin B2 and niacin intakes of the subjects didn't meet the Korean recommended allowances though there was no significant difference in nutrients intake between two groups. The value of sodium intake presumed from content of sodium excreted to urine, and Na content and Na/K in Korean cabbage Kimchi was higher in hypertensive. These results suggest that reducing of serum triglyceride, decreasing of sodium intake and changing the taste for saltiness can help develop the health status of the rural female hypertensive and control the blood pressure of them.

U.S. apparel brands are being imported to Korea more than any other country's apparel brands. Against this backdrop, this study intends to verify the fitness of U.S. apparels for Korean people in terms of size. To this end, the authors selected 25 American and 25 Korean women in their twenties and studied the differences of these two groups with regard to the size of their lower body parts. In addition, the authors analyzed how the size of each part of the lower body changes according to different postures. All the study subjects were required to be able to wear medium-sized pants of the U.S. apparel. The results of the present study are shown below. The American women were bigger than the Korean counterparts in leg length, hip circumference, thigh circumference, and all height-related sizes. However, the Koreans were bigger than their peers in lengths from waist to crotch; crotch length, body rise and the length from front waist point to hip line. Standing posture was used as a yardstick, when the changes in size according to the different postures were examined. The results indicate that hip and knee circumferences increased in the sitting posture. In particular, hip circumference significantly increased in the American women group. Regarding length-related sizes, increases and decreases in sizes for different lower body parts differed according to the posture. For a walking posture with ordinary strides, the front crotch length decreased while the back crotch length increased. This tendency was more notably observed for Korean women. The American woman clearly showed a decrease in outside leg length for all postures. The Korean women obviously presented an increase in the front center leg length for the sitting posture and for the posture where the knees were bent at $120^{\circ}$. The length from the front waist point to the hip line significantly declined in the Korean woman for the sitting posture and for the walking posture with ordinary strides.

Recently, people are becoming fatter in most parts of the world. Obesity is regarded as an important risk factor to adversely affect the health of humans, associated with hypertension, hyperlipidemia, diabetes, and cardiovascular diseases. In the present study, therefore, we tested the short time efficiency and safety of Bangpoongtongsungsan as a drug to decrease body weight in subjects with obesity. A total 48 volunteers (24 man, 24 woman) with body mass index (BMI : weight in kg divided by square of height in meters) of $23㎏/m^2$ participated in clinical study for 12 weeks, from 2008, March 01 to 2008, Jun 30. The subjects was received a dietary supplement of 12 pieces hard capsules per day (4 pieces in one, 3 times in a day) during the clinical study. At the end of clinical study, body weight of subjects was significantly decreased from $72.21{\pm}11.44\;kg$ to $70.53{\pm}11.67\;kg$ (p<0.05). Waist circumferences of subjects were reduced $91.58{\pm}6.43\;cm$ to $85.25{\pm}7.70\;cm$ (p<0.05). Also, a BMI of subjects was significantly decreased $26.07{\pm}2.35\;kg/m^2$ to $25.63{\pm}2.63\;kg/m^2$ (p<0.05). Particularly, a decrease in body weight, waist circumferences, and BMI was more significant in woman than man. But, other biochemical levels including lipid and glucose in plasma had no changes at the end of clinical study. In conclusion, administration of Bangpoongtongsungsan in subjects with high body weight fat could inhibit obesity associated with a decrease in body weight, waist circumferences, and BMI.
