This study was carried out to estimate the daily intake of Cd and the relationship between dietary intakes, serum level, and urinary excretions of Cd and Ca in 30 healthy adults living in rural area of Korea (12 males and 18 females). Analyses for the nutritional status of the subjects were performed by 3-day dietary intake record, duplicated diet collection, 24-hour urine collection, and venous blood sampling. The results were as follows: 1. The mean daily intake of energy was 2176.25kcal and 1613.85kcal in males and females of 20~49 years, and 1914.76kcal and 1517.90kcal in males and females of 50~59 years, respectively. The ratio of carbohydrate : fat : protein was 73.4: 13.6 :13.0 in males and 76.4 : 10.3: 13.3 in females. 2. The mean daily intake of Cd was 30.21㎍ in males and 36.8㎍ in females. And the 24-hour urinary excretion of Cd was 4.61㎍ in males and 6.07㎍ in females, which was 15.26% and 16.68% of the Cd intake in males and females, respectively. There was no significance between the dietary intake and the urinary excretion of Cd. 3. No significant correlation was found between the dietary intake and urinary excretion of Cd and intakes of nutrients. 4. The mean daily intake, serum level, and urinary excretion of Ca were 491.07mg, 8.93mg/㎗, and 80.73mg in males and 426.71mg, 8.82mg/㎗, and 80.26mg in females, respectively. 5. No significant correlation was found between the dietary intakes, serum level, and urinary excretions of Cd and Ca. It was concluded that the daily Cd intake was lower than the acceptable daily Cd intake of FAO/WHO but a little higher than that of other investigations. And the level of Cd intake had no effect on Ca status.

In this study, open type wind tunnel has been restructured instead air blower. its designed and fabricated part are diffuser. settling chamber with screen, contraction or nozzle, and test section. Also inverter enable to control variable speeds. And basic experiments have been performed to check the flow characteristics for restructured open type wind tunnel. In these procedures, we have got some conclusion. the control of contraction is valid for X = 0.40 considering Morel's and Fang's suggestion. it is confirmed that the two pressure coefficients for avoiding separation is satisfied with Fang's result. Distribution of uniform velocity in test section are stabilized above 95~99%.
