One of the problems for cultivating crops in the mountainous highland is soil erosion and nutrients runoff. Alternative cropping ways were searched to reduce soil erosion and to ensure farm income in the mountainous highland agricultural region. Three edible wild plants including goatsbeard, Korean thistle, and aster, were selected to test as alternative crops to reduce soil erosion in mountain agriculture of highland area. In the first year, the soil losses from the alternative cropping were 26 to 63 percents of the soil loss from summer radish cultivated by conservation tillage with contour and plastic film mulching. The relative soil losses in the second year ranged from 2.8 to 5.5 percents in comparison with radish cultivation. Rapid surface coverage contributed to successive soil loss protection by these alternative crops. Farm net profit of these crops was greater than that of radish. Monitoring of yields of Korean thistle or aster for further experiments, however, might be necessary for economic cultivation due to yield reduction caused by consecutive production.

Nowadays, the lighting of urban nightscape has become important for improvement in city. Lighting the outdoor is different that lighting an interior. Outdoor lighting designs should be designed to minimize glare, light trespass, light clutter and energy conservation to avoid light pollution. Mokpo city launched into a large scale project of the city beautification using outdoor lighting. However, outcomes of outdoor lighting project have faced strong opposition from environmental groups. This study aims to analyze the light pollution of outdoor lighting in Mokpo-si for creating a health night environment. The Radiant Imaging Prometric-1400 was used to measure the luminance of Yudal Mountain, Goha Island and Luminarie Street. The result showed that the all the outdoor lighting produce light pollution and some places like mountain and island did not need a lot of lighting all the time.

경상북도 울진군 서면 왕피천 유역 생태·경관 보전지역 내 천축산 자락의 고해발지역에 위치한 4개의 소규모 산지습지 식물군락의 다양성과 그 분포 특성을 밝히고자 한다. 서식처 유형과 종조성의 균질성을 고려한 Z.-M. 학파의 식물사회학적 식생조사 방법에 따라 총 26개의 식생자료가 수집되었다. 우점 상관에 따른 식생 구분과 종조성을 고려한 식생 유형분류를 통해 9개 단위식생으로 구성된 4개 상관형의 식생 분포가 확인되었다. 진퍼리새-꽃창포군락은 연구지역을 대표하면서 우점하는 식물군락이다. 인간의 이용 이후 방치된 균질한 입지에 자연천이로 식생이 발달하고 있으나 면적이 좁아 기타 식물군락의 분포는 드물게 관찰되었다. 습지별 미세지형과 수문환경은 식생의 다양성과 분포에 영향을 미치는 핵심요소로 확인되었다.

A large number of metallic relics were excavated by a team of Kyungsang University museum (Nov. 25, 1985 - Jan. 29, 1986) from the groups of tombs located at No. 9 Mountain,Okchun Village, Sungsan-Ri, Ssangchak-Myon, Hyopchun-Kun, Kyungsangnam-Do which are believed to date back to Kaya period. The Research Institute of Cultural Properties was in charge performing scientific conservation and restoration for the iron cuirass and horse halmet (for one year and seven months, Feb. '86 - Sep. '87)The scientific processing for them are as follows :1. Taken Photo and record the actual conditions prior to conservation.2. Taken radiography3. Elimate Goethite ($\alpha$-FeOOH) layer on the surface using Air-brasive, remaining Magnetite ($Fe_3O_4$) layer.4. Treat to dechlorinize with 3% Sodium-Sesquicarbonate5. Protected the relics with Ruscoat acryl resin using vacuum infiltration method.6. Joint the sherd using Araldite and Microballoon mixture.7. Restored missing parts by Araldite SV 427 and HV 4278. Made record and taken photo after restoration Several hundred of sherds of relics, small or large, were restored by assortment which this method for the purpose of contributing to the further study of ancient Kaya history.* Conservator, National Research Institute of Cultural Properties.

A method of conserving the vegetation at Mt. Chonggye was established to persue a practical management of the natural ecosystem by the vegetative composition analysis. As a result, the vegetation of surveyed areas was classified into two communities and four subcommunities in Mt. Chonggye. Potentilla fragarioides var. major community, known as the roadside plant community, distributed near trails under heavy human impacts. Potentilla fragarioides var. major community included two subcommunities : Digitaria sanguinalis-Ambrosia artemisiifolia var. elatior subcommunity and Rhus chinensis subcommunities. In these communiyies, there were many naturalized plant species such as Aster pilosus and Artemisia princeps var. orientalis, known as heliophilous plant. Results indicated that the vegetation had been affected by intensive human activities. It is necessary to control the naturalized plant species such as Aster pilosus for conservation of the ecosystem and nature in this area. Quercus mongolica community, a common coppice woodland in central Korea, was mostly distributed around mountain tops and ridges above 529 m altitute. In the valley where the forests well conserved, the Quercus mongolica community contained the Syneilesis aconitifolia-Hemerocallis lilioasphodelus subcommunity. On the other hand, Potentilla dickinsii subcommunity was dominated in dry rocky ridge areas. In these areas, however, the vegetation and forest soil was not properly managed for conservation.

This study was carried out to evaluate the analysis of environmental change (forest resources and soil water conservation by land types) after planting for prevention of between 2003 and 2006 from the stone hazarding areas in Guizhou province, China. Mean diameter growth of the trees was highest for Melia azedarach, followed by Robinia pseudoacacia, Lonicera fulvotomentosa, Choerospondias axillaris, Cupressus duclouxiana, and Eucommia uimoides Oliv. Mean height growth of the trees was greatest for R. pseudoacacia, followed by Ilex kudincha, M. azedarach, C. duclouxiana, C. axillaris, E. uimoides Oliv, Zanthoxylum bungeanum, and L. fulvotomentosa. Tree biomass was greater at the afforestation sites by 1.22-1.71 ton/ha compared to that of severely eroded mountain areas. The capacities of soil water conservation by land types were 2,790 ton/ha at latent rock desertification farmland, 2,655 ton/ha at rock desertification farmland, 1,680 ton/ha at dolomite sandstone hilly country, 1,650 ton/ha at halfstony hilly country, and 1,590 ton/ha at karst physiognomy site. Soil erosion was estimated to be 1,285 ton/$km^2$ which had been 2,178 ton/$km^2$ before afforestation. Also, we should be continuative manage after planting for prevention of the stone hazarding areas in Guizhou province, China.

본 연구의 목적은 2002년에 습지보호지역으로 지정된 천성산 화엄늪의 형성과정을 밝혀 지속가능한 습지관리를 위한 기초자료를 제공하는 것이다. 퇴적물 주상 시료와 부식의 탄소연대측정 결과로 볼 때, 화엄늪 습지보호지역의 초지는 지난 빙기의 기후변화와 관련없이 주민들의 화전농업에 의하여 만들어진 것으로 판단된다. 그리고 화엄늪은 천성산 정상부에 내린 강우가 지하로 침투하여 흐르다가 절리를 따라 능선 부분에서 용출하여 형성된 산지습지이다. 화엄늪 습지의 수량을 유지하기 위하여 습지보호지역 남서부의 주능선에 밀생하는 숲을 유지하여야 하며, 습지 하류 말단부를 지지하는 계단상의 거력제(block dam)가 붕락되지 않도록 유지하여야 한다. 그리고 습지의 주기적인 모니터링을 통하여 화엄늪 습지보호지역 내 지형과 수문변화를 측정하고 분석하여야 할 것이다.
