Korean folk medicine 'ORiNaMu' has been used mainly to cure toothache and alcoholism. With regard to the botanical origin of 'ORiNaMu', it has been considered to designate the branch of Alnus species (Betulaceae), but there was no pharmacognostical confirmation on it. To clarify the botanical origin of 'ORiNaMu', the anatomical characteristics of the branch of Alnus firma, A. hirsuta, A. japonica and A. maximowiczii were studied. As a result, it was found the morphological criteria for the four Alnus species that could discriminate them the number of cork cell layer, fiber, stone cell and diameter of vessel. According to there criteria, it was clarified that the commercial folk medicine 'ORiNaMu' was the branch of Alnus firma.

The purpose of this study is to investigate the optimal dyeing conditions and human-friendly properties of the extract from the branches of Alnus firma tree which is widely used for forestation and to provide basic information for quantification and commercialization of natural dyeing by discovering such as dye material. The optimal dyeing conditions, as a result, were shown at 100% of dye concentration, $90^{\circ}C$ of dyeing temperature and 40 minutes of dyeing time. In terms of dye uptake depending on the mordanting methods, it showed the best result in order of Fe, Sn, Cu and Al at pre-mordanting while found strong in order of Fe, Cu, Al and Sn at post-mordanting. Color fastness to washing and dry cleaning was found strong at grade 4-5 and fastness to light was rated at 2. The grade of change in color to rubbing and perspiration was good at 4-5. In aspects of functional properties, it showed excellent results of 98% deodorization rate at 120 minutes of dyeing time, 96.1% UV protection rate and 99.9% bacterial reduction against Staphylococcus aureus and Klebsiella pneuminiae. It is considered, therefore, the extract from Alnus firma tree is of great value as an eco-friendly natural dyestuff.

골프장 조경수와 잔디해충인 주황긴다리풍뎅이(Ectinohoplia rufipes)의 몇 가지 살충제에 대한 감수성을 실내에서 조사하였고, 사방오리(Alnus firma), 벚나무(Prunus serrulata var. spontanae), 은목서(Osmantus asiaticus)의 세기주식물에서 기 주식물에 따른 치사효과의 차이를 검토하였다. Cabaryl 40％+phosalone 20％ WP, chlorpyrifos-methyl 25% EC, chlorpyrifos 20% + diflubenzuron 7% WP, deltamethrin 1% EC, ethopenprox 8% +diazinon 25% WP, fenitrothion 50％ EC를 권장농도로 희석한 용액에 사방오리 잎을 침지시켜 먹이로 공급한 결과 chlorpyrifos-methyl을 제외한 모든 약제에서 주황긴다리풍뎅이 성충이 100% 치사하였다. 같은 종류의 농약이라 하더라도 기주식물의 종류에 따라 LC5o값이 2~6배의 차이가 있었는데 이는 기주식물 잎 표면의 물리적 성질이 다르기 때문인 것으로 생각된다. 야외와 실내 실험을 통한 약효지속 기간 조사 결과 deltamethrin의 약효가 가장 우수하였다.

물오리나무와 사방오리나무의 뿌리 줄기 및 가지에 있어서 목부요소의 크기의 변이에 관해서 연구하였다. 도관요소의 직경은 뿌리에서 가장 넓고 그 다음은 줄기이며 가지에서 가장 좁다. 그런데 도관요소의 길이는 줄기에서 가장 길고 다음은 뿌리이며 가지에서 가장 짧은 것으로 밝혀졌다. 섬유의 직경 및 길이는 뿌리에서 가장 넓고 길며 그 다음은 줄기 가지의 순이다. 각 기관의 일정위치에서 중심부로부터 연륜이 증가함에 따라 목부요소의 크기는 뚜렷하게 증가되었다.

In order to estimate effects of air pollution for pinus thunbergii forests arounding onsan industrial complex, structure of forest vegrtation was surveyed. In the survey of forest vegetation, pinus densiflora have been died or being withered, and importance value(I.V) of rhododendron mucromulatum and lespedeza spp. were low at the vicinity of industrial complex. Especially lespedeza maximowiczii and l. maritima were not entirely appeared at the vicinity of industrial complex. I.V. of quercus serrata, robinia pseudoacacia and alnus firma were preferably high at the vicinity of industrial complex, and those of smilax china, rubus crataegifolius and rhus trichocarpa were similar at every site and it could be guessed that those had a tolerance. Number of species had a difference over 10 species at the vicinity of industrial complex as compared with those of remote sites, and species diversity showed highly at the farther sites of industrial complex, and also at the low layer, number of species, species diversity and evennes were low at the vicinity of industrialcomplex and species weakened to air pollution were disappearing. It was possible that forest vegetation would be changed from pinus spp. to community of a. firma and r. pseudoacacia.

오염물질에 노출된 수목에서 잎의 발달 단계와 항산화 기능의 관계를 구명하기 위하여, 1월부터 6월까지 색소 함량과 항산화 활성의 변화를 조사하였다. 폐광지역과 공단지역내 수목의 스트레스에 대한 항산화 기능은 잎 발달과 함께 변화하며, 6월에 가장 높은 항산화 활성을 나타내었다. 항산화 물질 중 계절 변화와 상관을 나타내는 것은 카로테노이드, SOD 및 CAT였으나, 카로테노이드와 SOD는 정(+)의 상관을 나타냈고, CAT는 부(-)의 상관을 보였다. 또한 $H_{2}O_{2}$,를 제거하는 데 관여하는 APX와 CAT는 상호 보완적인 관계를 나타냈다. 가장 낮은 항산화 활성을 나타내는 시기는 4월이었으며, 이 시기에는 스트레스로 인해 피해 수준도 낮았다.

Effects of forest thinning on community level properties have not been understood yet in Korea. We investigated regeneration patterns and trajectories after a disturbance by applying a chronosequence approach. Light availability, litter and woody debris cover, and species composition were determined for twenty 50 m line-transect samples representing a disturbance duration gradient (within 11 years). Environmental factors such as light availability and coverage of woody debris and litter changed abruptly after thinning and then returned to the pre-disturbance state. Although species richness was gained at shrub and ground layer in a limited way in both forests, cover of various functional types revealed diversity in their responses. Notably, Alnus firma stands exhibited a larger increment of cover in woody plants. Ordination analysis revealed different regeneration trajectories between natural and planted stands. Based on ordination analysis, rehabilitated stands showed movement to alternative states compared with natural ones, reflecting lower resilience to perturbation (i.e., lower stability). Our results suggest that community resilience to artificial thinning depends on properties of the dominant species. But to get more explanatory ecological information, longer-term static observations are required.

The flora of Kunsan Wolmyong park was 77 families, 168 genera, 240 species, 2 subspecies, 35 varieties, 1 formae or 278taxa. Using the Phytosociology method, 12 plant communities were recognized ; Alnus japonica, Pinus densiflora, Pinus thunbergii, Pinus rigida, Castanea crenata, Quercus acutissima, Robinia pseudo-acacia, Alnus hirsuta, Quercus serrata, Aluns firma, Liriope platyphylla and Reynoutria communities. Similarity between different communities was low for most of the cases except for Pinus densiflora, Pinus Thunbergii and Pinus rigida communities kept comparely high with ond another. Species diversity was analyzed by species richness(SR), species diversity index(H') and evenness(J'). Castanea crenata, Robinia pseudo-acacia and Alnus firma communities were higher in SR, H' than the other communities. But Pinus rigida, Quercus acutissima and castanea crenata communities were higher in evenness than the other communities. To investigate the plant community structure and to establish restoration counter plan of a Wolmyeng Park in Kunsan City. As a remedial approach, following is propesed. first, Establishment of an adequate planting plan and development of slope stalilization method by planting native species. second, Sellection of adequate species by planting experiments for pioneer species, native species, and dietary species. third, Landscape planting zones should be managed artificially, the others be managed with ecological approach.
