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.

Igneolls rocks of the Hamyang area consist of Hamyang foliated granites and hornblende diorite. Hamyang foliated granites are classified into four rock types in terms of mineral composition and texture. The four rock types are foliated hornblende biotite granodiorite, foliated porphrytic granodiorite, foliated fine biotite granodiorite and foliated leuco granite. Petrochemical data of these rocks suggest that Hamyang foliated granites is calc-alkali rock series of differentiated products of cogenetic magma by fractional crystallization. Igneous rocks of studied area correspond to I-type, peraluminous and calc alkali rock series. Rb-Sr age and $Sr^{87}/Sr^{86}$ initial ratio for foliated prophrytic granodiorite is $200{\pm}Ma$and $0.711{\pm}0.0037$, respectively. K-Ar(hornblende) age of hornblende diorite is $179{\pm}9Ma$. These data come to an coincidence with Igneous activity of South Korea which were proposed by O.J. Kim(1975), that is, they correspond to Hamyang foliated granites of products of Songrim Disturbance, and to hornblende diorite of Daebo Orogeny.

Oriental liver fluke (Clonorchis sinensis) infection was surveyed among residents of Hamyang-gun, Gyeongsangnam-do, Korea during the period of January 2001 to March 2002. Total 1,041 stool samples were collected from residents who visited Public Health Center and its branches in Hamyang-gun and examined using formalin-ether sedimentation method. The overall egg positive rate was 16%, male showing higher positive rate (21%) than female (10%). The age group of 30 to 50 years had the highest egg positive rate of C. sinensis from 20% to 22%. The positive examinees were treated with praziquantel and educated individually to prevent reinfection . Egg positive rate in this area was decreased when compared with results recorded in the past, however, still remained more than 10%. This study suggests that periodic examination, treatment as well as education of residents should be continued and systematized.

U-Pb ages were determined from the granitic rocks from central and northeastern parts of Yeongnam massif. Porphyritic granite of Seosang-myeon, Hamyang-gun near the boundary with Anui-myeon shows age of $225.4{\pm}4.1Ma$. Foliated granodiorites of Anui-myeon, Hamyang-gun and Sinwon-myeon, Geochang-gun are $195.6{\pm}1.8Ma$ and $194.2{\pm}2.4Ma$ old respectively. Granites from Hari-myeon and Buksang-myeon of Geochang-gun show almost identical ages of $198.4{\pm}2.5Ma$ and $194.6{\pm}2.6Ma$ respectively, while foliated granodiorite of Yeongju shows an age ot $171.3{\pm}2.3Ma$. Combining with previously reported results, Triassic granitoids were emplaced almost identically at ca. 225 Ma throughout the areas of Hamyang and Sangju oi Yeongnam massif and Baengnok, Jeomchon and Goesan of Okcheon metamorphic belt. There were significant gap of non-magmatism before the resume of granitic activities over the large areas of Hamyang-gun, Geochang-gun, Gimcheon-si and Seongju-gun from Triassic-Jurassic boundary to early Jurassic, 200-194 Ma. Igneous activity within the Yeongnam massif of this period has not been reported from the Okcheon belt or Gyeonggi massif and may reflect distinct tectonic environment. Around 170 Ma, when Yeongju granodiorite was emplaced, there were active granitic magamtism throughout the Yeongnam massif, Okcheon belt and also Gyeonggi massif.

The objectives of this study were to form comparisons of total polyphenol compounds, the antioxidant activities and the urushiol contents of lacquer tree(Rhus verniciflua) bark and the sensory properties of chicken soup was made with lacquer tree bark that was cultivated from different cultivation areas; Hamyang, Wonju and China. Total polyphenol contents of Hamyang, Wonju and China were estimated as $375.28{\pm}3.48$, $403.60{\pm}6.6$ and $311.06{\pm}4.99$ mg/g. The total flavonoids contents of Hamyang, Wonju and China were measured as $374{\pm}14.12$, $683.70{\pm}12.64$ and $334.64{\pm}18.40$ mg/g. The total phenolic compounds and flavonoids concentration, DPPH radical scavenging activity, and ABTS radical scavenging of lacquer tree cultivated in Wonju were higher than the others; Hamyang and China. The urushiol content of lacquer tree bark from Hamyang was $4.59{\pm}0.04$ ppm and higher than others. Urushiol was not detected in China lacquer tree bark. Sensory evaluation tests for chicken soup containing lacquer tree bark showed that the scores of Wonju lacquer tree bark chicken soup was highest, however there are no differences between Hamyang, Wonju, and China significantly(p<0.05).

Pathogenicity of Korean entomopathogenic nematodes against local insect pests was different depending on strains or target-insect pests. Mortalities of diamondback moth, Plutella xylostella larvae were 51.8%, 77.8%, 96.3% or 100% in Hanrim Steinernema sp. and 50.0%, 74.1%, 96.3% or 98.1% in Hamyang Heterorhabditis sp. on filter paper when larvae were exposed to 3, 6, 12, or 24 nematodes per larva. Mortalities of them on kale leaves at the same concentration were 44.4%, 63.0%, 76.1%, or 94.5% in Hanrim Steinernema sp. and 79.7%, 81.6%, 94.4%, or 100% in Hamyang Heterorhabditis sp., respectively. In field test, control value of Hanrim Steinernema sp. was 72.0% and that of Hamyang Heterorhabditis sp. was 84.1% in 14 days when 300,000 nematodes were sprayed to each plot ($13.27\m^2$). Although mortalities of rice stem borer, Chilo suppressalis larvae showed no difference at high concentration, Hamyang Heterorhabditis sp. (47.3~100%) was more effective than Hanrim Steinernema sp. (34.3~83.3%) at low concentration, 50~200 nematodes/ml. When chestnut curculio, Curculio sikkimensis larvae were treated with Sancheong Steinernema sp. and Hamyang Heterorhabditis sp., respectively. When pellucid zygaenid, Pryeria sinica larvae were exposed to nematodes, Pocheon Steinernema sp. was effective ranging from 96.7% to 100% but mortalities of them were 63.3~76.7% in Dongrae Steinernema sp..

We investigated natural background and enrichment characteristics and predicted geochemical disaster for stream sediments in the Hamyang-Sancheong area. Stream sediments samples were collected 95 ea in study area. The stream sediments were well known that had not possibility of contamination effect and represented drainage basins. We got the major and hazardous elements concentrations by XRF, ICP-AES and NAA analysis methods. Acid decomposition for the ICP-AES has been used $HClO_4$ and HF with $200^{\circ}C$ heating at 1st and after that $HClO_4$ HF and HCl with $200^{\circ}C$ heating at 2nd stage. We could know the characteristics that concentration of Cu and Co decreased when concentration of $SiO_2$ increased in correlation analysis. The enrichment factor of the stream sediments was below 2 in study area. This result indicated that study area belonged to moderate enrichment. The stream sediments of Hamyang area were enriched in order of Pb>Th>Cr>V>Co>Cu and those of Sancheong area were enriched in order of Pb>Th>Cr>Co>V>Cu. The enrichment factor(E.F.) of the Pb, Cr, Co and V was similar between Hamyang and Sancheong area. The enrichment factor of the Th was higher in Hamyang area and that of the Cu was higher in Sancheong area. The enrichment factor of the Pb was highly enriched in all study area than earth crust mean. But we could know that study area was not exposed to the pollution of the Pb through the tolerable level.

This study was conducted to establish a management plan for the Sangrim Woodlands restoration by analyzing the site characteristics of the Sangrim Woodlands Natural Monument(Natural Monument 154) in Hamyang-Gun, Gyoungsangnam-Do, Korea. Site preparation to enhance soil aeration should be applied because soil bulk density in all study sites was higher than soil compaction of natural forest soil area. Herbaceous plants could be introduced to hard soil strength for restoration of areas compacted by visitors. Also, visitors around forest areas should be restricted to enhance natural soil restoration. Soil pH in the Sangrim Woodlands was between 4.18 and 4.90. The values were lower than pH 5.34 of Korean forest soil originated from metamorphic parent materials. Lime fertilizer could be applied to reduce soil acidification in the woodlands. Short and long-term management plans such as periodical fertilizations to improve plant growth should be established to restore the Sangrim Woodlands which have high soil compaction, low soil pH and organic matter content.
