A vitrification process is under development in KEPRI for the treatment of low-and medium-level radioactive waste. Although the project is for developing and building Vitrification Pilot Plant in Korea, one of KEPRI's concerns is the quality control of the vitrified glass. This paper discusses a methodology for the estimation of glass composition by on-line measurement of molten glass properties, which could be applied to the plant for real-time quality control of the glass product. By remotely measuring viscosity and density of the molten glass, the glass characteristics such as composition can be estimated and eventually controlled. For this purpose, using the database of glass composition vs. physical properties in isothermal three-component system of SiO$_2$-Na$_2$O-B$_2$O$_3$, a software TERNARY has been developed which determines the glass composition by using two known physical properties(e.g. density and viscosity).

Purpose : The purpose of this study was to investigate the effects of a combined exercise program using a ballet bar and elastic bands on the body composition, physical strength, and postural correction of middle-aged women. Methods : The subjects were 28 middle-aged women with no ballet experience. They were divided into an experimental group (n=14; exercise group) and a control group (n=14; non-exercise group) through random sampling. The experimental group underwent an exercise program using a ballet bar and elastic bands for 50 minutes twice a week for 12 weeks, whereas the control group performed no exercise. The subjects in both group had their body composition, physical fitness, and postural angles measured before and after the intervention. A paired t-test was used to compare pre- and post-test values within each group, and a two-way repeated measures ANOVA was employed to compare pre- and post-test changes between the two groups. Results : Regarding body composition, statistically significant differences in BMI (p<.05), body fat percentage (p<.001), and muscle mass (p<.001) were observed between the two groups before and after the intervention. For physical fitness, the experimental group showed statistically significant increases in quick reflexes (p<.001), muscle endurance (p<.001), and muscle strength (p<.001). For postural correction, the experimental group exhibited statistically significant decreases in all variables: the head (p<.001), shoulder (p<.001), cervical tilt (p<.001), right-left pelvic tilt (p<.001), and anterior-posterior pelvic tilt (p<.001). Conclusion : A combined exercise program using a ballet bar and elastic bands had positive effects on the body composition, physical fitness, and postural correction of middle-aged women.

The purpose of this study was to examine the effects of hemispheric damage in body composition of male adults with stroke experiences. The Fourth and Fifth Korea National Health and Nutrition Examination Surveys (KNHANES) with body composition results obtained from the DXA (dual-energy X-ray absorptiometry) assessments were used for this study. Survey data of 18 post-stroke men and 28 healthy controls were obtained. Both the lean and fat masses of the upper and lower limbs were utilized to compare for the compositions between the limbs in post-stroke subjects. In addition, the effect of exercise habit was also observed for the influence of physical activity in body composition. Mixed results in left and right limb compositions were shown between the groups. When the subjects were further divided based on walking days per week, sedentary (walk ${\leq}2d/wk$) post-stroke group showed significantly greater fat mass and less lean mass than the physically active people (walk ${\geq}3d/wk$). In comparison to the healthy sedentary and physically active controls, two post-stroke groups showed greater variations. The results indicate that physical activity maintains or improve the quality of both the upper and lower limb composition in patients with post-stroke men.
