In order to survey the prevalence of parasites in soil from playground in a housing development testate, 368 samples were taken from playground 184 unit. The survey was carried out during 2 months from september in 1999 to October in 1999. The results were obtained as follows; 1. Eggs of toxocara canis were detected in 25 samples (6.8%) from 368 cases of playground. 2. The 3 kinds of eggs were isolated from the soil of playground. Those were strongyloides spp 13.9%, toxocara canis 6.8% and toxascaris leonina 2.4%. 3. It was mixed infestation such as single (80.0%) and double (20.0%).

A total of 1,024 sera were collected from cattle(227), pigs(465), chickens(257) and dogs(75) raised or slaughtered in Daejeon metropolitan city from April to September 2002. Japanese enceplvlitis virus(JEV) antibodies in sera were detected by the haemagglutination inhibition test. The prevalence rates of JEV antibodies were 99.1%, 54.0%, 63.0% and 98.7% in cattle, pigs, chickens and dogs, respectively. In case of cattle and dogs, the monthly antibody-positive rates were as high as 85.7-100.0% and there were no differences among six months. In case of pigs, the monthly antibody-positive rate showed the lowest in April(6.4%) and the highest in July(100.0%) and it remained above 50% during the summer-time. In case of chickens, the monthly antibody-positive rate was 100.0% in July & August, 80.5% in June, 40.0% in May, 7.5% in September and 5.0% in April in order and there were distinct differences in seasons.

To evaluate the hypoglycemic effect of propolis, streptozotocin (STZ) induced diabetic rats were divided into 4 groups such as, diabetic control group, low dose of propolis (0.1 ml) group, medium dose of propolis (0.3 ml) group and high dose of propolis (0.9 ml) group and feeded with propolis extracts for 30 days. After experiment, oral glucose tolerance test (Oral GTT) was carried, and 16 hours fasting blood sugar levels, body weights, blood lipid levels were measured. Finally, pancreatic histopathological study was performed. In conclusion, the propolis is effective to the treatment diabetes due to the reduction of the blood sugar level and the regeneration of the damaged $\beta$-cells shown in streptozotocininduced diabetic rats.

In order to survey the prevalence of parasites in soil from playground in a detached dwelling area, 162 samples were taken from playground 54 unit. The survey was carried out during 3 months from July in 2000 to september in 2000. The results were obtained as follows: 1. Eggs of Toxocara canis were detected in 30 samples (18.5%) from 162 cases of playground. 2. The 3 kinds of eggs were isolated from the soil of playground. Those were Strongyloides spp 23.5%, Toxocara canis 18.5% and Trichuris vulpis 4.3%. 3. It was mixed infestation such as single (74.5%), double (23.7%) and triple(1.6%).

In order to survey the prevalence of Toxocara canis in soil of playground in a detached dwelling area, 150 samples were taken from playground 50 unit. The survey was carried out during 3 months from July to September in 2006. The Egg of Toxocara canis were detected in 6 samples(4.0%) from 150 cases of playground. The prevalence of T canis by month was 6.0% in July, 4.0% in August, 2.0% in September, respectively. This study results suggested that the prevalence of T canis were decreased in 2006 compared to 18.5% (30 positive/162 samples) in 2000.

Objective & Methods: This study aimed to evaluate the effects of Cistanches Herba herbal-acupuncture (CH-HA) at KI10 (Umgok) on osteoporosis induced by ovariectomy in mice. The results were as follows; Results: CH-HA at KI10 significantly inhibited the overgrowth of tibia, the elevation of serum osteocalcin Level, the reduction of tibial Ca and P Level, the increase of tibial osteoclast Like cells, the reduction of tibial TBV (trabecular bone volume), the overgrowth of tibial GPL (growth plate Length) in ovariectomized mice. NP at KI10 significantly inhibited the reduction of BMD (bone mineral density) in ovariectomized mice, but CH-HA did not. Conclusion: Taken together, CH-HA at KI10 has a protective or therapeutic effect for osteoporosis in ovariectomized mice. Therefore, it is suggested that CH-HA may be an useful therapeutics in clinical filed after further researches.

This study was conducted to investigate the geochemical factors governing the distribution of heavy metals(Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) in the marine surface sediment samples collected from the Samcheonpo coal-fired power plant. Variations of absolute metal concentrations were related to those in textural and/or carbonate and organic matter content. Most elements, except for Pb, showed generally lower contents compared with the average shale concentration, and the effect of anthropogenic input appeared to be minimal in the sediments. Computations of LF%(labile fraction) and EF(enrichment factor) based on all trace metal data indicated the presence of mineralogical control for Co, Cr, Cu, Ni, and Zn, and anthropogenic contamination for Pb, which needs to be considered in the design of long term monitoring programmes.
