This study aimed to compare energy nutrient intake, health related factors, physical characteristics, blood biochemical indices, prevalence of metabolic syndrome and odds ratio (OR) of metabolic syndrome based on dietary fat energy ratio. Subjects were 1,205 men aged 40~64 years. The average fat intake was 52.8 g. Subjects were divided into three groups (deficient, normal, excess) based on dietary fat energy ratio. The dietary fat energy rations of the three groups were 36.9%, 42.9% and 20.2%, respectively. Energy and protein intake were increased significantly with dietary fat energy ratio (p<0.001), whereas carbohydrate intake decreased (p<0.001). In health related factors, amount of smoking alone showed increase based on dietary fat energy ratio (p<0.001). In comparing physical characteristics, blood pressure and blood biochemical indices, excepting diastolic blood pressure, increased significantly based on dietary fat energy ratio (p<0.01~p<0.001). The rate that exceeded criteria in risk factors for metabolic syndrome was higher in the serum triglyceride (41.2%) and was lower in the waist circumference (22.2%). Prevalence of metabolic syndrome was 37.9%, and showed significant correlation to dietary fat energy ratio (p<0.05). The OR of metabolic syndrome was higher in deficient and excess group than in normal group, but it had no relationship between fat energy ratio and metabolic syndrome. The results of this study provide basic data to establish fat intake guidelines for prevention of metabolic syndrome in middle-aged men.

In this study, the authors applied a modified SRF product quality based on a mix of disposable plastic bags and bulky waste to estimate the mixing ratio which can be the energy efficiency of coal for fuel. This study was performed to find physical properties of bulky wasteand element analysis for the mixd disposable plastic bag. Also, SRF (solid recovery fuel) was tested to figure out, physicochemical properties by standard method. As the results, the physical properties of bulky waste shows 89.6% of wood. Then the author measured disposal plastic bag as follows : [3 : 7], [5 : 5], [7 : 3] quality criteria by the mixing ratio of bulky waste. The low calorific value was proportionally increased whenever the mixing ratio of disposable plastic bag was increased. Therefore, the author can surmise that the mixing ratio between bulky waste and disposable plastic bag was [6 : 4]. It shows 5,950 kcal / kg value as much as coal fuel.

Gd-157 material has very large neutron capture cross section in the thermal region. So it is very useful to shield material for thermal neutrons. Futhermore, in the neutron capture experiment and calculation, the neutron absorption and scattering are very important. Especially these effects are conspicuous in the resonance energy region and below the thermal energy region. In the case of very narrow resonance, the effect of scattering is to be more considerable factor. In the present study, we obtained energy dependent neutron absorption ratios of natural indium in energy region from 0.003 to 100 keV by MCNP-4B Code. The coefficients for neutron absorption was calculated for circular type and 1 mm thickness. In the lower energy region, neutron absorption is larger than higher region, because of large capture cross section (1/v). Furthermore it seems very different neutron absorption in the large resonance energy region. These results are very useful to decide the thickness of sample and shielding materials.
