  • This paper compares the difference between the village groves in the Jinan settlement region and the Hamyang settlment region in Honam and the Youngnam mountainous region. The results are as follows: Fifty-one village groves in the Jinan legion were found and 40 village groves were found in the Hamyang region. It was established that the village groves in the Jinan region of Honam province were conserved better than those of Hamyang region of Youngnam province. In the Jinan area, the village groves were principally found in the Jinan-eup and the Hamyang regions, primarily in Seosang-myun and Aneui-myun. So it was determined that the village groves were distributed inequitably in the two regions. In L / W ratio, the Jinan region is 3.6 and Hamyang region is 2.0 Jinan is 1.8 times greater than Hamyang. Therefore, it was concluded that Jinan is stronger than Hamyang in linear function of the village groves. Stone stooge for complementation function was found in 11 village groves in the Jinan region and 6 village groves in Hamyang. So the percentage of the remaining stone storage is 15-20 % of all village groves. Regarding grove makeup, the village gloves in Jinan region is deciduous forest principally. In contrast, the groves of Hamyang are principally coniferous forest. The dominant tree of the Jinan-gun region is Zelkova serrata, but in Hamyang it is Pinus densiflrora. By number, Hamyang region has two times the trees than Jinan region. In density of stand, the Hamyang region is 76.2% higher than Jinan region. In height and diameter of trees, the Jinan region is greater than the Hamyang region. It was identified that RSI of both region is 40%. So in density of trees, both region are sparse. This paper has a limit in ideiltiting the differences between Yolmg-nam ar\ulcorner Hnam village groves because comparative review only examined two regions.

  • Penicillium sp. CB-20 was selected for its strong polygalacturonase activity among various strains of molds found in soil. It was found that the production of polygalacturonase reached to maximum when on the wheat bran medium containing pectin as carbon source, the strain was cultured for 60 hours at 3$0^{\circ}C$. The enzyme was purified to 29.21 food by ammonium sulfate treatment, Sephadex G-25, G-15, G-150 gel filtration, DEAE-cellulose and DEAE-Sephadex A-50 ion-exchange chromatography. Yield of the enzyme purification was 2.31 %. When the purified enzyme was applied to sodium dodecyl sulfate polyacrylamide gel electrophoresis, the molecular weight was estimated 21, 000. The amino acid composition indicated relatively high contents of gultamic acid, glycine and histidine.

  • The intradermal(ID) test has been widely used in Korea and several reports about the results of the ID test are known. We examined the egg of Clonorchis sinensis(C. s.) by ID test in 443, stool's egg-counting technique in 79 and direct smear(cellophane thick smear technique) in 1304 subjects. The results are as follows.: 1. The positive rate of C. s. was 3.8% out of 1304 persons. 2. The sensitivity of ID test was 82.1% out of 39 persons and, the specificity was 64.6% out of 404 persons. 3. The false positive of ID test 35.4% out of 404 persons and, the false negative was 17.9% out of 39 persons. Intradermal test is a rapid, sensitive and useful supplementary diagnostic tool for the detection of Clonorchiasis infection and must be used as screening test with direct smear of stool but cross reaction with other helminth infections and moderate false reaction are the main disadvantages in its practical application.

  • We analyzed community forming patterns and forest vegetation of goldenrain tree communities in Anmyeondo, Daegu Naegokdong, Pohang Youkangri, Yanghakri, Balsanri, Daedongbaeri, Mophori and Seochonri. The vegetation data for analysis collected from 68 quadrats of 8 sites Using the Braun-Blanquet method, from April 2002 to September 2003. A total of 201 species were found and the area was covered with $30\~100\%$ of tree layer, $0\~90\%$ of shrub layer and $20\~100\%$ of herb layer. Oplismenus undulatifolius, Pueraria thunbergiana, Quercus dentata, Clematis apiifolia, Ligustrum obtusifolium, Rosa multiflora, Artemisia princeps var. orientalis, Humulus japonicus and Robinia pseudo -acacia were the species in high frequency. To analyze the community classification and ordination, we used the technique of TWINSPAN and DECORANA. The surveyed areas with 68 quadrats were divided into 3 groups by TWINSPAN and divided into 3 communities with axis 1 date volume by DECORANA.

  • The purpose of this study was to investigate the evaluation of regional antagonism in children and adolescents in Youngnam and Honam region. There were 684 subjects included in this study from three ages in the Youngnam and Honam regions: 12.8 years(6th grade, n=208), 14.8 years(8th grade, n=211), and 16.9 years(10th grade, n=265). Of the 684 subject, 357(53.3%) were boys and 327(47.8%) were girls. The instruments consisted of subjects' self-reported social distance, stereotype, and prejudice. The data were analyzed by frequencies, t-test, one-way ANOVA and the $Scheff\'{e}$ test. Major findings were as follows: The mean score of the out-group stereotype was greater than the median, so the in-group preference was greater than the out-group exclusion. The in-group stereotype was different based on the age and the sex. The 6th and 8th graders and the boys were higher than 10th and the girls. The prejudice was different based on the lesion. The social distance was different based on the age and the region.

  • Soil enzyme and microbial activities are affected by fertilizer and compost applications and can be used as sensitive indicators of ecological stability. Microbial population and soil enzymes viz., dehydrogenase, urease, acid phosphatase and aryl-sulphatase were determined in the long-term fertilizer and compost applied paddy soil. Soil samples were collected from the four treatments (control, compost, NPK and compost+NPK). Long-term NPK+compost application significantly increased activities of urease, dehydrogenase and acid phosphatase than all other treatments. The compost application enhanced activities of urease, dehydrogenase and acid phosphatase than the NPK application. However, arylsulfatase activity was not significantly different between compost and fertilizer application. The highest microbial population was recorded in the NPK+compost treatment. The compost application also resulted in higher microbial population than the NPK application. The above results indicate that ecological stability could be maintained by application of compost alone or with NPK.

  • Purpose : This study was conducted to evaluate the effect of denture placement on nutrition status and quality of life in the urban elderly Material and method : The first survey was conducted from 45 targeted elderly people(25 experimental group, 20 control). In the first survey, information on general characteristics, chewing ability, food intake and nutrient intake, anthropometric measurement, and degree of satisfaction in life were obtained. The second survey was conducted to evaluate the effect of denture placement with same method as the first survey. Results : Before denture placement, there are no statistical significant differences (in general characteristics, chewing ability, nutrient intake, anthropometric measurement, and degree of satisfaction in life) between experimental group and control. But after denture placement, survey shows that there is statistically significant difference in chewing ability between two groups. The experimental group have higher intake of energy, protein, carbohydrate, iron, and vitamin C. in nutrient intake. And after denture replacement, there is significant improvement in degree of satisfaction in life. After denture placement there are significant changes in agitation and attitude toward own aging according to Lawton's factor classification. Conclusion: In short, this study shows that chewing ability improvement of the elderly has strong positive effects to their food intake, nutrient status and quality of life.

  • This study was conducted to investigate the superoxide dismutase (SOD) characteristics and antioxidant activity by nonenzymatic(Fe$^{2+}$/Ascorbate) and Fe$^{3+}$-ADP/NADPH method in perilla(Perilla frutescens var. japonica Hara.) and jaso(Perilla frutescens Briton var. acuta Kudo.) leaves. The characteristics were evaluated by the nitro blue tetrazolium reduction method. Perilla leaves contained three or four major SODs depending on the varieties. The inhibitor test indicated that the Perilla leaves contained two Cu /ZnSODs and one or two FeSODs, but Jaso leaves have only Cu/ZnSOD. However, no varietal differences were detected in the Cu /ZnSOD isozyme patterns. FeSODs, however, showed different varietal isozyme patterns through the different combinations of the two FeSOD isozymes. Among MeOH extractes, "mil yang 2" showed very strong antioxidant activity. Relatively large differences in the levels of SOD and antioxidant activity detected in the Perilla varietites. There was significantly different in the comparison between perilla leaves and red jaso leaves.s.etween perilla leaves and red jaso leaves.
