Purpose : This study was conducted to evaluate the effect of denture placement on nutrition status and quality of life in the urban elderly Material and method : The first survey was conducted from 45 targeted elderly people(25 experimental group, 20 control). In the first survey, information on general characteristics, chewing ability, food intake and nutrient intake, anthropometric measurement, and degree of satisfaction in life were obtained. The second survey was conducted to evaluate the effect of denture placement with same method as the first survey. Results : Before denture placement, there are no statistical significant differences (in general characteristics, chewing ability, nutrient intake, anthropometric measurement, and degree of satisfaction in life) between experimental group and control. But after denture placement, survey shows that there is statistically significant difference in chewing ability between two groups. The experimental group have higher intake of energy, protein, carbohydrate, iron, and vitamin C. in nutrient intake. And after denture replacement, there is significant improvement in degree of satisfaction in life. After denture placement there are significant changes in agitation and attitude toward own aging according to Lawton's factor classification. Conclusion: In short, this study shows that chewing ability improvement of the elderly has strong positive effects to their food intake, nutrient status and quality of life.

To investigate processes of solute transport, the Navier-Stokes equation was used to represent flow structure and then advection-diffusion equation was used to simulate distribution of solute concentration. The QUICK and the central difference schemes were used to treat advective and diffusion terms. The QUICK (Quadratic Upstream Interpolation for Convective Kinematic) difference scheme, based upon assuming quadratic upstream interpolation rather than linear interpolation between the grid points, has a stable convective(advective) sensitivity. The distribution of COD concentration was simulated based on discharge and COD level of riverine inflower, with coastline given before and after reclamation respectively.

우리 벤처기업인도 세계화 시대의 흐름에 맞는 정신적 무장을 해야한다. 벤처기업의 세계화 전략은 매우 중요한 경영전략으로 인식되고 짜여야 한다. 벤처기업은 앞으로 더 큰 시장을 향한 세계지향적 기업으로 발전해 나가야만 한다.
