This study was conducted to understand the distribution characteristics of old tree (protected tree) and propose the effective management plan for old tree to make hold a sustained function as natural and cultural resources in rural area. We surveyed 96 old trees at 69 farm villages in Yaesan-gun, South Chungcheong Province. The species of tree was investigated with Zelkova serrata, Ginkgo biloba, Quercus acutissima, Pinus densiflora, Celtis sinensis, and Juniperus cbinensis order. Most of them located at the inside (43.6%) and the entrance (35.1%) of a village, and at mountain slope (31.9%) and alluvial plain (25.3%) in terms of distribution topography. The existing place of pollution source was investigated with 61%, and the pollution sources were blocks, construction materials, cement packings, farm machines and living garbage. The place where the rates of bare ground were more than 50% for the root region of a protection tree was 63%. The tree surgical operation was investigated in 37.5% of protection trees, and 12.5% of protection trees were investigated with a tree surgical operation being immediately. The average score for health condition of old tree at study sites was 18.6 points. A monitoring class was divided by public monitor 59.3%, main monitor 38.5%, and dead tree 2.2% on the basis of that information. Hereafter, we will conduct to promote the management guideline and develope culture contents through additional investigation.

There is a need to analyze unconfined groundwater behavior since the demand of groundwater use has been increasing. While unconfined groundwater temperature is tend to be affected by air temperature, it is hard to find an empirical study in South Korea. In this research, we try to determine the relationship between daily average air temperature and daily average groundwater temperature by time-sequential analysis of groundwater monitoring wells in Galshin basin in Yesan-Gun, Chungcheongnam-Do. In addition, models to estimate groundwater temperature from air temperature were developed. In this research 101-day moving average method with measured air temperature is used to estimate groundwater temperature. To verify the developed model, estimated values of average groundwater temperature with 101 moving average are compared to the measured data from September 10 2007 to September 9 2008. And, Nash-Stucliff Efficiency and Coefficient of Determination were 0.970 and 0.976, therefore it was concluded that the model allowing groundwater temperature estimation from air temperature is with reasonable applicability.

To evaluate the value of a preserved tree as rural landscape resource, the growth environment and health condition was investigated, and the image evaluation was implemented on land~ape architectural major undergraduate students for zelkova trees in Yesan-gun. The image evaluation results of zelkova trees were as followings; 1) Typical image of preserved tree examined by Semantic Differential Scale were 'Old', 'Big', and 'Good'. 2) The 'big' image of zelkova tree and the height of tree, the width of tree crown, the breast girth of tree, the root girth of tree, the external formation of tree, and the health of tree bark is mutually related. Especially, the correlation between the 'big' and the external formation and the width of tree crown is high. 3) Typical image of preserved tree examined by Likert Scale were 'Natural', 'Green', 'Peaceful', and 'Rural'. 4) The preservation necessity for preserved tree was highly related with the state of ground, and the management necessity for preserved tree was highly related with contamination level and the state of ground. The appropriate management plan for preserved tree are proposed to improve the quality of rural landscape(basis of these results).

Pungsu theory is important one in the site selection and lay-out of traditional Korean village and house. In this aspect, Study with a view of Pungsu theory might be used as a proper method for understanding the traditional architecture in Korea. In this context, this study analyzes the Jeong, Dong-Ho's house which is designated no. 19 as an important folk cultural heritage, located in Jigok Ochu-gil 133-62, Godeok-myon, Yesan-gun, Chungnam province. The analysis of the site and space lay-out is carried out by Yong(Dragon), Hyoel(Auspicious Spot), Sa(Sands), Su(Water) aspects of the Pungsu(Fengshui) Hyungsei-ron. The house is depending upon soft dragon vein connecting with a earth type rear mountain. It looks southeast direction, Gonjwasonhyang(乾坐巽向). The hyeolseong(穴星) has classical venus shape, and there is no faults relatively. The Sasinsa condition is almost perfect that right blue dragon and left white tiger surround the hyeol with 3-4 layers and the facing mountain covers the front open area. The water flowing from inside of left and right mountain is joined in front of the house so it could stop flowing out of vital energy. Bibo forest(裨補樹) is placed properly to protect the easy disclose of water outlet. The house is well organized western house(西四宅) by analysis of Dongseosataek-ron(東西四宅論). Through the analysis, I found that the house has good Pungsu(Fengshui) environment fitted with Pungsu Hyungsei-ron. The house composed of small thatched roof is enclosed several times by low hills of back, left and right side. So it is believed that the site might be carefully evaluated by Yong, Hyoel, Sa, Su of Hyeongsei-ron for knowing whether the site condition could minimize the demage by strong winds and protect from the winter cold wind and secure water for drinking and farming and then selected. The method of Pungsu for evaluating the geographical condition of surrounding of a site is used as a traditional site analysis method for evaluating the suitability of long-term well and safe residence.

To investigate the effect of partial tillage seeding of hairy vetch on green manure biomass and rice yield, on-farm experiment was conducted at eco-friendly hairy vetch cultivation area located in Yesan-gun, Chungcheongnam-do. Seeding methods of hairy vetch consisted of partial tillage seeding (PTS) and broadcasting before rice harvesting (BBRH). Hairy vetch was incorporated into soil on May 18 and rice seedling was transplanted on May 26. The growths of hairy vetch before overwintering were investigated on November 11. Plant height of BBRH plot was longer than that of PTS plot, but somewhat larger number of seedling stand was found in PTS. Biomass and N production of hairy vetch were investigated on May 18. Results of the investigation showed no difference between two seeding methods. Although the seeding time was 21 days late in PTS, the biomass of hairy vetch and rice yield were equivalent to those of BBRH seeding, so we conclude that PTS could improve overwintering survival of hairy vetch in rice cropping system.
