The author conducted a retrospective study of 40 patients with uveitis, ages ranged from 14 to 73, and classified those patients as anterior uveitis, panuveitis and pars planitis. The frequencies of occurence, causes and clinical laboratory tests were compared to those. The results were as follows. 1. Of the 40, 33(82.5%) were anterior uveitis, 3(7.5%) were posterior uveitis, 2(5%) were panuveitis. 2(5%) were pars planitis. Of the 40, 22(55%) were idiopathic, 4(10%) were Behcet's disease, 3(7.5%) were traumatic. 2. Of the 40. 27(67.5%) have positive findings that is one or more among the 12 classes of clinical laboratory tests. 13(32.5%) have negative findings in overall tests. 3. In the roentgenography, 1(2.5%) has positive finding, and 3(7.5%) have positive findings in the routine urinary analysis. 4. In the test of complete blood count, 11(27.5%) showed increased blood count. Neutrophil count was higher in the posterior and panuveitis than in the anterior uveitis and panplanitis. 5. In the test of erythrocyte sedimentation rate, panuveitis showed the highest value, anterior uveitis showed the lowest value in average. 6. 1(2.5%) was positive in teh test of VDRL and FTA-ABS, all were negative in the test of antinuclear antibody test, 2(5%) were positive in teh test of rheumatoid factor. 7. In the Behcet's skin test, 2(5%) were positive, of whom, one was anterior uveitis, 1(33%) with posterior uveitis, 1(50%) with pars planitis. 8. In the test of ELISA, 18(55%) showed positive ratio in the patients with anterior uveitis, 1(33%) with posterior uveitis, 1(50%) with pars planitis. 9. In the test of serum electrophoresis, 1(33%) showed the positive ratio in the posterior uveitis, 1(50%) with panuveitis, 2(6%) with anterior uveitis. 10. All of 12 recurrent cases(30%) had anterior uveitis. Of these patients, 42% showed increased WBC count, while 27.5% showed increased WBC count in the uveitis patients with first attack.

A series of experiments were performed to investigate the kinetics of dissolution reaction between palladium powder and iodide solution. This investigation examined the effects of oxygen, pH, iodide and iodine concentration, initial PdI₄² concentration and temperature on the dissolution of palladium. A half order reaction rate was found with respect to I₃^- and a third order reaction rate with respect to I^-. But the reaction rate was decreased with increasing initial concentration of PdI₄^(2-). The activation energy of reaction was 2.4kJ/mole, which implied that the dissolution reaction was controlled by the diffusion reaction.

This study developed a new yanggaeng(red bean sweet jelly) by adding Peucedanum japonicum powder from 5% to 20%. It has been evaluated its physicochemical, sensory characteristics and antioxidant activity. The DPPH radical scavenging activity of Peucedanum japonicum powder was 40.53% and the total phenolic compound content was 13.36 mg/100 g. Moisture content of yanggaeng with Peucedanum japonicum powder added 5~15% was 50.24~48.32% significantly higher than in the control group(p<0.05). The hardness of yanggaeng was 2,748.25 g/m2 in control and the PY5 and PY10 were 4,012.05 g/m2 and 4,019.40 g/m2 respectively, significantly higher than control(p<0.05). However, when the amount of Peucedanum japonicum powder was increased by more than a certain rate, it decreased again, as 2,155.39 g/m2 in PY20. As a result of the acceptance test of the yanggaeng, the flavor of yanggaeng with Peucedanum japonicum powder was evaluated significantly higher than control(p<0.05), but PY20 was 5.20 not significantly difference with PY10. The overall acceptance of the yanggaeng showed the lowest value of 4.00 in the control, PY15 showed significantly high value as 7.80(p<0.05). Compared with the control, the acceptance of samples with Peucedanum japonicum powder 5~15% was higher than that of control. It was concluded that 10% and 15% of the Peucedanum japonicum powder could be added for the development of the yanggaeng. According to the above study result, to enhance the utilization of Peucedanum japonicum for developing functional food would be possible, and a new yanggaeng product by adding Peucedanum japonicum would have good potential.

In this study, the traditional takju was manufactured using the finger root, which was recognized as a health functional ingredient, and analyzed the physicochemical and sensory quality characteristics according to the period of fermentation. The pH was significantly low(p<0.05) in all samples until the second day of fermentation, and the pH tended to increase again from the third day of fermentation. The pH value was decreased as the amount of finger root was decreased(p<0.05). The acidity of takju was significantly lower at 0.17~0.21 immediately after fermentation(p<0.05). The acidity of FR0 showed significantly the highest value(p<0.05). The sugar content of takju was significantly increased in all the samples until the 2nd day of fermentation(p<0.05). On the 7th day, it showed the lowest value at 11.01~ 12.63 ° Brix. The sugar content of FR0 was significantly lowest value(p<0.05). The alcohol content of takju was significantly increased as the fermentation proceeded, and the highest value was 11.90~13.50% at 7 days(p<0.05). The alcohol content of RF0 was significantly higher than other samples(p<0.05). As a result of organic acid analysis of finger root takju fermented for 7 days, citric acid(3.35%) showed the highest content of FR3(p<0.05). The content of fructose increased with increasing finger root amount (p<0.05). As a result of sensory evaluation of finger root takju, FR1 and FR2 samples tended to be lower in score than FR0, and FR3 showed the highest score. The overall acceptance value of FR0 was 7.5 and FR3 was 7.57.

It was studied that the trace amounts of thorium in Na₂WO₄ solution was removed through the adsorption of thorium by ferric hydroxide. The adsorption of thorium in Na₂WO₄ solution took place above pH 10. When the concentration of Na₂WO₄ was higher than 0.050M, the adsorption of thorium was increased with increasing pH. The increase of Na₂WO₄ concentration caused the adsorption of thorium to decrease. The increase of temperature caused the adsorption of thorium to decrease. The adsorption of thorium by ferric hydroxide followed Freundlich isotherm.

A study has been made on the solvent extraction of platinum, one of the platinum group metals, with diluted tri-n-butyl phosphate(TBP). Systems involving hydrochloric acid as extract-promoting agent have been studied in the distribution of platinum(IV) chloride. The distribution coefficient for platinum(IV) chloride goes up through a maximum at just over 6M HCI and 50% TBP in toluene, but decreases at low and high HCI concentration. IL was found that the extracting species has the formula 3TBP·H₂PtCl_6·χH₂O. Unextracted platinum(IV) in the aqueous phase is determined directly and platinum(IV) in the organic phase is stripped with H₂O and determined by stannous chloride method, respectively. In a binary mixture of gold and platinum, the solvent exhibited toward gold that it could be extracted selectively from platinum.
