The prevalence of antibody against hepatitis C virus (anti-HCV) was investigated in 331 patients with various liver diseases from April 1992 to September 1992. The presence of anti-HCV was detected by Lucky HCD EIA test in 331 cases and by (Ortho HCV Antibody ELISA test 148 patients) The results are summarized as follows: 1. Overall, antibody to HCV(anti-HCV) was positive in 37(11%) of 331 patients with various liver diseases. 2. 16(11%) of 144 patients with chronic hepatitis, 2(5%) of 37 patients with alcoholic liver disease, 17(22%) of 76 patients with liver cirrhosis and 2(5%) of 38 HBsAg carriers were positive for anti-HCV.None of 12 patients with acute hepatitis, 11 patients with drug induced hepatitis and 13 patients with hepatocellular carcinoma was anti-HCV positive. 3. HBsAg positivity in patients who had anti-HCV was 24%(9/37). 4. A positive correlation was found between Lucky HCD and Ortho HCV test. Of 128 Lucky HCD negative cases, 124 cases were negative for Ortho HCV ELISA and 4 cases were positive for Ortho HCV ELISA Of 20 Lucky HCD positive cases, 11 cases were positive for Ortho HCV ELISA and 9 cases were negative for Ortho HCV ELISA. These results suggest that hepatitis C virus has an important etiologic role in HBsAg negative chronic hepatitis and liver cirrhosis in Korea. The diagnostic value of Lucky HCD EIA test may be slightly better or equivalent to Ortho HCV ELISA test in the diagnosis of Hepatitis C virus infection.

This study investigated participants who have taken part in Hapkido continuously, in view of age, carrier in exercise, and gender and then analysed how these factors affect continuous participation in Hapkido. 1) The significant factors which enable the participants to continue Hapkido were revealed as health/physical fitness(71.67%), enjoyment / interrest (58.13%), self-protetio / guard(48.28%), phychological benefits(20.94%) 2) The factors of continuing Hapkido were different in ages, which showed significant differences in phychological benefits, skill fulfilment / challenge, accomplishment / position, charm, recreational activity. The response represented specifically in one or two areas in case of younger participants. The more aged, it showed relatively even distribution to the various responses due to the broaden span of thoughts. 3) The factors of continuing Hapkido were different in carrier, which showed significant differences in self-protection / grard, skill fulfillment / challenge, accomplishment/ position in different experiences in exercise. By the time of reaching first phase and second phase, it is thought to show the psychological effect of continuing exercise unconsciously in various areas. 4) The factors of continuing Hapkido were not different in gender, which implicated the fact that the overall attitude and thoughts on Hapkido of female participants and male participants are similar.

This study investigated geochemical characteristics of acid mine drainage(AMD) discharged from the abandoned coal mine and gold mine. Water sample of acid mine drainage were collected from 9 locations at Hwasun, Kwangyang, Chonam, Taback and Sangdong area. The yellowish and brown color of evaporated material was prepared by air dry for 9 acid water samples during 20 days in the laboratory As the 9 acid water samples become fully drying, the concentration of this water become progressively more concentrated and its may be eventually reached saturation with respect to either gypsum or ferrohexahydrite. The value of density for acid mine drainage increase with increasing TDS and EC values. The value of activity for acid mine drainage increase with those real ion concentration. The x-ray powder diffraction studies identified that the evaporated materials were gypsum, ferrohexahydrite and kaolinite. Diagnostic peaks used for identification of gypsum were the 7.62, 4.28, 3.80, 3.07, 2.88, 2.68, 2.22, 1.90 and 1.62Å peaks. Diffraction peaks at 6.00, 5.48, 5.13, 4.89, 4.40, 3.46, 3.20, 3.03, 2.97, 2.94, 2.79, 2.27 2.09Å may indicate ferrohexahydrite. In the SEM and EDS analysis, the crystals of acicular and columnar in the evaporated materials probably shown the gypsum.

This study has focused on mineralogical and geochemical characteritics of evaporated minerals from the mine waters and on variation of constituents in mine water during the evaporation The evaporated minerals are shown in mine waters at the field. In order to form of evaporates in the laboratory, mine waters were sampled from the abandoned mine area(HS, LG and BJ) and were air dried in laboratory for room temperature. During the evaporation of mine waters, TDS, EC values and the concentration of major and minor ions increased, whereas dissolved oxygen(DO) values decreased with the sampling time. Gypsum, epsomite, kaolinite, dolomite and illite were identified in BJ sample, gypsum and epsomite were observed in LG sample, and gypsum, epsomite and vermiculite were founded in HS sample by x-ray powder diffraction studies. The infrared spectra for evaporated minerals show major absorption banded due to OH stretching, adsorbed molecular water and sulfate stretching, respectively. Evaporated minerals were heated at 65, 150, 250 and 350℃ for 1 hour in electrical Furnaces. Gypsum transformed the bassanite at 150℃ heating temperature and epsomite transformed the hexa-hydrite at 65℃, and then converted the kieserite at 250℃. With increasing heating temperature, the intensity of absorption OH band(3407 11㎝^(-1)), adsorbed molecular water band (1654.39㎝^(-1)) and sulfate stretching band (1113.46㎝^(-1)) were decreased, whereas sulfate stretching bands(668.35㎝^(-1) and 603.85㎝^(-1)) were relatively increased in IR due to dehydration.

This study investigated geochemical characteristics of the mine drainage discharged from the abandoned coal mine in the Hamback area. Sampling of stream waters(21) were carried out in the Hamback area. The pH, EC, TDS, Eh and Do contents were measured in field and ions such as Na, K, Mg, Ca, Mn. Fe, S r , Al. Cr, Cu. Zn, Ge, As, Mo, Cd, Sb, Ba, Pb, F, Cl. No₃ and SO₄ were analyzed by GFAAS, AAS, ICP-AES, ICP-MS and IC. In stream waters, pH values increased, whereas total dissolved solids(TDS), electrical conductivity(EC) and dissolved oxygen(D0) values decreased with distance. Eh negative values a t upstream site were found, suggesting that its caused by the organic material in the retention pond, and these value in stream water effluent from the retention pond increased progressively with distance. The concentration of toxic heavy metals and major cations except Na, Cl, No₃, Cu, Mo and Sb decreased rapidly due to retention pond, but the concentration of Na, Cl, No₃, Cu, Mo and Sb increased gradually with distance. The concentration of Na, Cl and No₃ increasing with distance, which indicate by domestic waste. Major ions, such as Na, K, Ca, Mg, F, Cl, SO₄ and HCO₃ were statically analyzed in order to investigate relationship with TDS contents. M is observed that TDS contents have-positive relation with K, Ca, Mg, F, so4 and HC0₃ contents, but negative relationships with Na, Cl and No₃ contents. Most stream surface waters showed a calcium-sulfate and noncarbonate hardness dominating water quality type. In geochemical modeling for stream surface waters, the saturation index of gibbsite were oversaturated with respect to gibbsite.

Nizatidine is a newly introduced potent H2-receptor antagonist of acid secretion with long duration of action. For evaluation of clinical efficancy and safety, twenty one patients with endoscopically proved thirteen gastric ulcers and eight duodenal ulcers were treated with nizatidine 300mg at bed time via per os for 6 weeks. The results were as follows 1. The rate of complete endoscopic healing of duodenal ulcer 92.3% and 87.5% after 6 weeks. The overall healing rate of peptic ulcer was achieved in 89.9% at 6 weeks. 2. Clinical symptoms disappeared in 84.6%, 92.3% and 100% of patients with duodenal ulcer and 75.0%, 87.5% and 87.5% patients with gastric ulcer at 2, 4 and 6 weeks respectively. 3. There were not developed any symptoms and signs suggesting side effect of drug. In conclusion, data from this study suggest that nizatidine 300mg p.o. at sleeping time is effective and safe in treatment of peptic ulcer disease, and is well tolerated on a short-term basis.
