The purpose of this study was to investigate the effect of Monacolin-inoculated rice embryo on the body fat and serum lipid profiles in 61 obese elementary school students. The subjects divided into two groups 31 obese children had the experimental diet (rice embryo inoculated Monacolin) and 30 obese children had the control diet three times a day after meals. The mean age, height, weight, and BMI of 61 subjects were $10.5\pm0.5$ years, $143.6\pm6.8cm,\;55.0\pm8.9kg,\;and\;26.1 \pm3.9$, respectively. The changes of body fat mass (kg) in experimental group and control group after 6 weeks were -0.60kg and -0.03kg, respectively. The changes of body fat $(\%)$ in experimental group and control group after 6weeks were $-1.44\%\;and\;-0.25\%$, respectively. These changes of body fat in experimental group were significantly higher than in control group (p<0.05). The change of total-cholesterol in experimental group and control group during 6weeks were -17.52mg/dL and -1.70mg/dL, respectively. The change of LDL-cholesterol in experimental group and control group during 6 weeks were -17.06mg/dL and - 2.80mg/dL, respectively. The change of triglyceride in experimental group and control group after 6 weeks were -9.58mg/dL and 11.67mg/dL. Total-cholesterol, LDL- cholesterol and triglyceride of experimental group after 6 weeks significantly decreased compared to control group (p<0.05). After experimental diet (6 weeks), total-cholesterol was negatively correlated with body water contents, soft lean mass and fat free mass (p<0.05). Triglyceride showed a significantly positive correlation with body weight and body fat mass, however, it was negatively correlated with fat free mass (p<0.05). HDL-cholesterol showed a significantly positive correlation with fat free mass (p<0.05). These results show that Monacolin-inoculated rice embryo is effective in decreasing body fat and blood lipid in obese children.

The purpose of this study is to observe the longitudinal changes in BMI (Body Mass Index) of obese and non-obese 3rd. grade high school students in Seoul for 12 years and to see the trends of overt weight gain in obese adolescents. The results are as follows; 1. The average annual increasing rates of body mass Indices in male students were $1.14kg/m^2$ in obese group and $0.59kg/m^2$ in non-obese group. In female students, the average annual increasing rates of body mass indices were $0.93kg/m^2$ in obese group and $0.53kg/m^2$ in non-obese group. 2. The change rate of BMI for 12 years was significantly higher in obese group than non-obese group. 3. Puberty had less influence on the change rate of BMI in obese group compared to non-obese group. 4. In obese group, 71.8% of the variance in BMI at 17 can be predicted by BMI at 16 years in male students. In female students 44.4% can be predicted by BMI at age 16. 5. Among the 17-year-old obese students, 58.8% of the males and 56.2% of females were found not to have been obese at 7 years of age. 6. Among the 17-year-old obese students, those who were obese at 7 years of age were found to have higher BMI at later ages than those who were in the non-obese group. Obese adolescents were more likely to be obese in their childhood than non-obese group. There was no optimal age for the significant weight gain and the increasing rate of BMI was constantly higher in obese group than in non-obese group. Due to the fact that child obesity in early age contributes to obesity in adolescence, close observation is advised. On the other hand, a large proportion of obese adolescents can be preventable by early interventions, because about 50% of obese adolescents were not obese in early elementary school age.

The purpose of this study was to investigate the effects of modified fasting therapy using Gamrosu and herbal medicine on the changes of body compositions in women. We analyzed the medical records of 11 patients, who carried out modified fasting therapy at Dunsan Korean Medicine Hospital of Daejeon University. Body compositions (body weight, body mass index, body fat mass, skeletal muscle mass, basal metabolic rate, extracellular water ratio, abdominal circumference, thickness of abdominal subcutaneous fat, visceral fat area) were reviewed before and after modified fasting therapy. The body composition values (body weight, body mass index, body fat mass, skeletal muscle mass, basal metabolic rate, extracellular water ratio, abdominal circumference, thickness of abdominal subcutaneous fat, visceral fat area) decreased after modified fasting therapy. Results from this investigation showed that modified fasting therapy using Gamrosu and herbal medicine has positive effects on changes of body compositions.

To determine whether 17$\beta$-estradiol induces the morphological changes in adipose and liver tissues, we measured the effects of 17$\beta$-estradiol on adipose tissue mass, adipocyte histology and hepatic lipid accumulation in female ovariectomized (OVX) C57BL/6J mice. Compared to vehicle-treated control mice, 17$\beta$-estradiol-treated mice decreased adipose tissue mass and the size of adipocytes, and concomitantly increased the number of adipocytes in a dose-dependent manner. In addition, the administration of 17$\beta$-estradiol resulted in reduced hepatic lipid accumulation in a dose-dependent manner. These results suggest that estrogen may regulate adipocyte development and lipid metabolism in female OVX C57BL/6J mice.

The adsorption experiment of phenol(Ph) from aqueous solution on granular activated carbon was studied in order to design the fixed-bed adsorption column. The experimental data were analyzed by unsteady-state, one-dimensional heterogeneous model. Finite element method(FEM) was applied to analyze the sensitivity of parameter and to predict the fixed-bed adsorption column performance on operation variable changes. The prediction model showed similar effect to mass transfer and intraparticle diffusion coefficient changes suggesting that both parameter present mass transfer rate limits for GAC-phenol system. The Freundlich constants had a greater effect than kinetic parameters for the performance of fixed-bed adsorption column. FEM solution facilitated prediction of concentration history in solution and within adsorbent particle.

Inside of working PDP, there exist highly reactive conditions in the gap between two glass panels. MgO film and phosphor have been investigated as a function of discharge, also phosphor and sealing frits have been investigated as a function of temperature. Changes of impurity generation of MgO, phosphor and sealing fits were measured by using x-ray photoelectron spectroscopy (XPS) and quadropole mass spectroscopy (XPS) and quadropole mass spectrometer (QMS). Impurities such as CO, $CO_2$, OH and $H_2O$ were increased during discharge and heating treatment. Gaseous impurities such as carbon compounds and water deteriorated the characteristics of PDP operation during of lifetime. So metal is used to remove the impurities of phosphor and sealing frits during hearting, the result that the quantity of the impurities such as carbon monoxide and water was reduced.

The modern architecture has to find more essential configuration order rather than the spatial order in the reasonable feint. In other side, paintings and sculptures as a part of the building in the past become a pure art and develop an abstract art. Also they make many affects on the modern architecture as a paradigm. New material has brought to the new forms and the changes of the overall culture and art. One of the new changes has made the object that is one of unique culture symptoms in the 20C and the general part of the modem art includes it. The wall that limits the inside area through mass and volume before the recent times had treated as the object to express the special mean and character. However, the wall has developed as a component that consists of the internal space through surface and volume rather than mass or structure since the recent times. Now, I survey the objective tendency of the wall in the modem interior architecture mainly focused on the relation between object in the abstract art and wall inside.

We fabricated the optical system of merocyanine dye using Langmuir-Blodgett(LB) technique because quite uniform orientation could be obtained, which is one of the most important factors to affect to its optical characteristics. The resonance frequency and other electrical parameters at the parallel resonance state were measured using the impedance analyser(HP 4294 A). Also the morphological changes of dye molecules after UV irradiation were observed using AFM. The parallel resonance frequency and resistance by electrical equivalent circuit were decreased with the UV irradiation and these aspects are different from general mass adsorption process. Therefore the structural changes of dye molecules are being considered, that is, the aggregated molecules become dissociated. It indicates that the shifts of the resonance frequency and the others occurred without mass absorption.

It is necessary to deal with the process capability index carefully because it has been developed with certain assumptions. Companies make a decision on processes through the results obtained by using and treating data extracted from the processes. However if they have incorrect or wrong results, they cannot lead to proper outputs but also bring to loss of the competition in quality. Therefore, this study will show a method to analysis Cp (process capability ; CP) and an idea of mass-production on Pp (process performance ; PP) based on the Sigma Estimate which is one of the uncertainty in the process capability index and makes a lot of error. To apply this method, it is essential to understand and to analyze the processes exactly. Especially, it is required to establish the more accurate process capability index that can quickly and properly respond to changes on processes to recognize the small changes on the process which lies in specification in mass production system that the continual monitoring of quality managers is required.

The objective of this study was to investigate the relationship between changes in body temperature, adiposity and sympathoadrenal activity in normal weight female college students, eating an instant-noodle lunch in a laboratory setting at ambient temperatures of 22-24.8$^{\circ}C$. Preprandial epinephrine(EPI) concentration, as an indicator of adrenal activity, was inversely and significantly correlated with body weight, body mass index(BMI), and waist girth. Changes in pre- and postprandial EPI concentrations showed positive correlations with % body fat, fat mass, waist girth, hip girth, and waist/hip girth ratio(WHR). The preprandial norepinephrine (NE) concentration was negatively correlated with recovery time from the peak postprandial core temperature to the meal-start core temperature(RTST). However, the NE concentration, an indicator of sympathetic neural activity, was not related to anthropometric measurements in normal weight young women. In conclusion, adrenal activity was negatively associated with adiposity and central body fat distribution. Sympathetic activity was related to body temperature regulation capacity after a meal, but was not related to adiposity in normal weight young women. (Korean J Nutrition 31(7) 1130-1138, 1998)
