  • This study was intended to examine the zinc status of free-living adult women living in the Taegu region. Zine intake of 102 female subjects was measured by food frequency method for 3 consecutive days. Urinary zine was assessed from urine samples collected fir twenty four hours. Average dietary zinc intake of adult female subjects using food record was 5.9$\pm$1.8mg which was 49$\%$of Korean RDA. When zine intake by frequency method was higher than by food record. Average urinary zine intake by frequency method was higher than that by food record. Thus, it appeared that zinc intake by frequency method was higher than that by food record. Average urinary zinc excretion of 102 adult female subjects was 0.28$\pm$0.16mg, which belonged to marginal zinc deficiency range. Fifty nine of 102 subjects showed marginal zinc deficiency as assessed by urinary zinc excretion. If we compare the zinc status of adult female subjects by age group, zinc intake in the 50s was significantly higher than any other age groups. However, there were no significant differences in zinc status according to BMI groups and BMI groups. Significant correlations were found between zinc intake and energy, protein, carbohydrate and fat intake. Based on dietary zinc intake and urinary zinc, we concluded that zinc status of adult female living in the Taegu region is marginally deficient.

  • This study was carried out to estimate the relationship between dietary intakes, blood levels, and urinary excretions of zine, copper, and iron and serum lipids in 30 healthy adults living in Korean rural area. Analyses for the nutritional status of the subjects were performed by 3-day intake recored, duplicated diet collections, 24-hour urine collection, and venous blood sampling before measuring of blood pressure. The daily intakes of zinc, copper, and iron estimated for 3 days were 8.2mg, 3.0mg, and 12.7mg in men and 8.4mg, 3.7mg, and 12.3mg in women, respectively. The serum contents of cholesterol, triglyceride, and HDL-cholesterol were 165.9mg/dl, 119.4mg/dl, and 43.7mg/dl in men and 154.1mg/dl, 88.2mg/dl, and 47.1mg/dl in women, respectively. The serum levels of zine, copper, and iron were 146.0ug/dl, 120.3ug/dl, and 131.1ug/dl in men and 140.6ug/dl, 117.3ug/dl, and 112.2ug/dl in women, respectively. In the relation between dietary intakes, serum levels, and urinary excretions of these minerals, there were significantly positive correlation between zine intake and copper intake(p<0.05), copper intake and urinary excretion(p<0.001), and iron intake and serum zine level(p<0.05). In the relation between these minerals and serum lipids, dietary zine showed positive correlation with triglyceride(p<0.05), and serum zine/copper ratio showed negative correlation with HDL-cholesterol (p<0.05).

  • The changes of selenium and zine contents of transitional milk and mature milk at 7 and 60 days postpartum were comparatively studied on 20 Korean lactating women. the selenium and zinc contents of transitional milk and mature milk were analyzed by atomic absorption spectrophotometer after wet-digestion. The mean selenium contents wer 12.2$\mu\textrm{g}$ /ι and 11.5$\mu\textrm{g}$/ι at 7 and 60 days postpartum, respectively. The mean zinc contents decreased significantly from 4.23mg/ι at 7 days to 1.62mg/ι at 60 days postpartum (p<0.05).

  • Spot welded structure is operated in diverse situation because of temperature, humidity and precipitation. In addition factors of environmental pollution such as acid rain, that courses corrosion, have the tendency to increase, But spot welded structure strength is affected by dampness and environment temperatures. Therefore, it is important to evaluate effect of temperature of spot welded part, In this study, the strength distribution of spot welded plates is evaluated about the environmental temperature of zine coated steel plates and test is conducted with welded part immersed in distilled and synthetic sea water. Specimens are immersed into water for 10, 100, 500 and 1000hours to evaluate the effects of water immersion time on tensile-shear strength under the conditions of -40, 0, 20 and $50^{\circ}C$. Strength is evaluated by tensile-shear test. The conditions of spot welding are 240kgf electrode force, 10KA welding current with 0 and 5mm clearance. From this study, spot welded specimens with clearance have lower tensile-shear strength in the distilled water or synthetic sea water comparing with spot welded specimens without clearance. And they have lower tensile-shear strength under $-40^{\circ}C$ and over $50^{\circ}C$.

  • The layered basic zinc p-toluenesulfonates has been directly synthesized by the surface modification. The chemical formula of layered basic zinc p-toluenesulfonate is determined by CHNS and TG-DTA. From the X-ray diffraction data and the guest size, the orientation of the p-toluenesulfonate onto the zinc hydroxide layer is determined. The molecular plane of the p-toluenesulfonate lies perpendicular to the zinc hydroxide layers.

  • The eliminating of organic compound is essential process of the recovery of zinc sulfate from zinc sulfate waste water contained organic compound. The ozone oxidation and adsorption treatment is good for eliminating of organic compound in waste water. The zinc oxide treated an excess of sulfuric acid for zinc sulfate. We got zinc sulfate 740g from water 1kg.
