This study was carried out to analyze the vegetational structure of the express highway. Seven sites in roadside slopes of the Kyungboo express highway (the section Pankyo-Shingal) were selected and quadrats of three sizes, 25㎡, 5㎡, 1㎡, were set up for trees, blush, herbs, respectively. The results obtained are as follows; 1) For trees, R. pseudo-acacia showed the most high value, 45%, 39%, respectively in relative density and relative cover. Relative frequency was most high(31%) in P. rigida. Among invading species, Quercus spp. showed the most high value. For blush, Puerarica thunbergiana and Lespedeza bicolor showed very high value in R.D., R.F., and R.C. Arundinella was most high in R.D., R.F., and Miscanthus sinensis in R.C. for herbs. 2) In importance value, R. pseudo-acacia showed very high value over all polt. R. pseudo-acacia also showed markedly high value in phoytograph index, making the highest layer. 3) Species diversity was most high in Plot 2, the community of R. pseudo-acacia - Alnus hirsuta. Plot 1, the community of Quercus spp. - Alnus hirsuta, was most high in evenness. And dominance value was most high in Plot 5, the community of R. pseudo-acacia, showing the most low species diversity.

This study was to provide the fundamental data for vegetation recovery and efficient management of fire-burned forest area. For the purpose of this study, natural and artificial forests reproduced after fire burning were selected, including 7 sites of natural forests consisted of various fire-burned dates and 4 sites of artificial forests of 4 dominant tree species, Larix leptolepis, Pinus rigida, Chamaecyparis obtusa, Robinia pseudo acacia, and were investigated about species compositions and diversities. Obatained results are as follows : 1. By the community differential table the plant communities of this area are classified by Quercus acutissima - Lespedeza bicolor - Pteridium acquilinum community, Q. dentata - Pinus densiflora community, and Q. mongolica - Rododendron mucronulatum -Miscantus sinensis community centering around Quercus spp. in natural forests, and each Larix leptolepis, Pinus rigida, Chamaecyparis obtusa, Robinia pseudoacasia community consisting of species planted for the afforestation in artificial forests. 2. Natural forests are appeared to possess abundant species as the mean no. of species occured in the area are 49 species of natural forests and 39 species of artificial forests, and No. of species occured only in the natural forests and the artificial forests are 37 species and 31 species, respectively. 3. In natural forests Quercus acutissima, Quercus mongolica, and Rhododendron mucronulatum had the most high importance value in canopy layer, under layer, and shrub layer, respectively. Quercus mongolica and Rhododendron mucronulatum showed increased importance values with passing time after the fire. 4. In artificial forest, tree species that showed the most high importance value in each canopy - subtree - shrub layer were Chamaecyparis obtusa - Celtis sinensis - Deutzia parviflora in Chamaecyparis forest, Pinus rigida - Quercus acutissima - Quercus mongolica in Pinus rigica forest, Robinia pseudoacasia - Robinia pseudoacasia - Quercus serrata ini Robinia pseudoacasia forest, and Chmaecyparis obtusa - Callicarpa japonica without subtree layer in Chamaecyparis otusa forest. 5. Species diversity (H′) of natural forests was the most low value in Siljun area having the shortiest passing time after the fire, on the other hand Yumboksa area having the longgest one was the most high value and in artificial forests Larix leptolepis forest showed the most high value and Robinia pseudoacasia the most low one with the highest dominance. For species diversity of each crown layer, subtree layer in natural forests and shrub layer in artificial forest showed the most high value.

This study was to analyze the quantitive and structural changes and the distributional characteristics of forest communities in Mt. juwang area with respect to physiographic location. 16 sites were selected, including every 8 site of ridge part and glen part, slow slopes and steep slopes, respectively. Obtained results are as follows: 1. Mean D.B.H. of trees of upperstory was most gret in the steep slopes, mean tree height in the glen part, and tree age in steep slopes. 2. Mean D.B.H. and tree age of trees of middlestory was most great in the steep slopes, and mean tree height in the slow slopes. 3. In the upperstory, Pinus densiflora showed the highest importance value regardlessly topographical location. 4. In the middlestory, Quercus mongolica showed the highest importance value in the ridge part, and Acer pseudo-sieboldianum in the other part. 5. Lindera obtusilaba showed the most high importance value of lowerstory regardlessly topographical location. 6. Species diversity(H′) were the most high in glen part and slow slopes- and dominance (1-J′) in ridge part. 7. As a result of Cluster Analysis, it was appreared forest communities in this area formed one group. 8. As a result of Polar Ordination analysis, Pinus densiflora communities and Carpinus laxiflora communities were situated in the loggest distance due to very different structure of tree species and density of tree individuals. 9. Pinus densiflora, Quercus variabilis, and Quercus alieana appeared to be in the decline regardlessly topographical location, and those tree species were replacing with Fraxinus spp. in ridge part and steep slopes, and with carpinus laxiflora and Fraxinus spp. in glen part and steep slopes.

This study was Carried out to analyse species composition, species diversity and structure and variation trends of vegetation, of Mt. Odae, Mt. Sobaek, and Mt. Juwang following various latitudes and topographies which were in middle temperate zone in Korea. Obtained results are as follows : 1. As a result of the simple discriminant analysis, soil texture Showed the highest high percent contribution of each environmental factor to the discriminant of Studred area. And Mt. Odae showed high content of sand while Mt. Juwang Showed silt. 2. Mean stem density showed highest value in Mt. Juwang and mean D. B. H. was Mt. Odae, and on phisiographic locations showd high values of stem density and mean D. B. H in slow slope area, nothern aspect area, and high elevation area, in order. 3. Species that showed the highest importance value in each canopy-subtree-shrub layer in study area were Quercus mongolica-Acer pseudo-sieboldianum-Lindera obtusiloba were in Mt. Odae, Betula platyphylla var. japonica-Styrax obassia-Deutzia parviflora were in Mt. Sobaek, and Pinus densiflora-Acer pseudo-sieboldianum-Lindera obrusiloba were in Mt. Juwang. 4. Species that showed the highest importance value in each canopy-subtree-shrub layer on the physiographic location were Quercus mongolica-Acer pseudo-sieboldianum-Lindera obtusiloba in high elevation and southern aspect, Carpinus laxiflora-Acer pseudo-sieboldianum-Lindera obtusiloba in high elevation and southern aspect, Carpinus laxiflora-Acer pseudo-sieboldianum-Lindera obtusiloba in nothern slope, Carpinus laxiflora-Styrax obassia-Lindera obtusiloba in low elevation, and Betula platyphylla var. japonica-Styrax obassia-Deutzia parviflora in high elevation. 5. According to decrease of latitudes with going down from Mt. Odae to Mt. Juwang, the more Number of species and individuals were increased, and the deversity index was the highest value in Mt. Sobaek, the evenness was in southern aspect, and the dominance was in high elevation. 6. As a result of Cluster analysis, the study area were divided into 4 groups, Carpinus laxiflora community, Styurax obassia community, Deutzia parviflora community, and Quercus mongolica community. 7. As a result of COA analysis, communities of the study area were divided into Betula platyphylla var. japonica community, Deutzia parviflora community, Quercus mongolica-Acer pseudo-sieboldianum community, and species were divided into 4 groups as the major, the disturbed, the waterside, and the fertile. 8. As results of the simple discriminant analysis and the linear regression, sand and silt content, slope aspect, total nitrogen content, and elevation among environmental factors had high percent contribution to classification and ordination of vegetation communities of the study area. 9. Major tree species had the unstable layer structure due to lower importance values of canopies and subtrees than those of shrubs, and Pinus laxiflora and Betula platyphylla var. japonica were on the decline phase due to very low dominance and absence of next generation. while, Styrax obassia and Acer pseudo-sieboldianum were sustanable layer structure as being distributed on all the crown layer.

This study was to analyze comparatively for major chemical and nutritional components of Pinus densiflora needle that have widely used in Korean traditional medicine and to evaluate the pharmacological and nutritional values of that, and to provide the fundamental informations on development of the red pine needle medicine through verifying propriety of prescriptions of Korean traditional medicine. The results were summarized as follows: 1. In Correspondence Analysis to the similarity between species and terpenoids, terpinolene, bonyl acetate, and α-cadinol were closely situated to Pinus densiflora, while α-pinene, β-pinene, campene, β-phellandrene were so in relatively long distance to Pinus densiflora that the terpenoids were appeared to be impartially distributed in other needle species. 2. Each terpenoids in Pinus densiflora needle were contained as relatively even quantities, while terpenoids of needles of other species were very variant and contents of certain terpenoids were remarkably high, and, thus, such a variance would be background that peoples or animals did not choose other species that caused rejection when they ate. 3. By analysing the pharmacological effectiveness of plants containing plentifully certain components, terpenoids of Pinus densiflora needle were appeared to have varied function such as renewal promotion, blood­circulation promotion, analgesic, sedative, antiinflammatory, expectorant, antibiotics, vermicide, and fragrance. 4. In Correspondence Analysis to the similarity between species and terpenoids, salicylic acid and vanilic acid were closely situated to Pinus densiflora, and phenolic and tannin compounds of Pinus densiflora needle were considered to have the effect of anti­virus and vermicide, respectively. 5. Nutritional value of Pinus densiflora needle was appeared to be superior than other grains, and if the way to annex terpenoids to needle powder is developed, the fragrance and the preventative effect to geriatric diseases would be more excellent. 6. Korean traditional medicine seems to make prescriptions and preparations of red pine needles harmonizing with various diseases.

This study was to provide the fundamental data for efficient reservation and management of the Mt. Odae experiment forest of Dongguk University. Obtained results are as follows : 1. As results of simple discriminant analysis, contents of silt and sand showed the most high contribution percent to the discriminant between each physiographic location, ridge and glen parts, steep and slow slopes, and high and low elevation, and among those locations steep slopes were the poorest soil condition. 2. By the community differential table the plant communities of this area are classified by Quercus mongolica―Acer pseudo―Sieboldianum―Rhododendron schlippenbachii community, Carpinus laxiflora―Styrax obassia―Lindera obtusiloba community, Pinus densiflora―Quercus serrata―Lespedeza spp. community, and 3 species groups that mainly appear in ridge part, glen part, and high elevation area, respectively. 3. Quercus mongolica showed the high importance value in ridge part, steep slopes, high elevation area, Carpinus laxiflora n glen part, and Pinus densiflora in low elevation area. 4. Glen part had more rich species than ridge part, and slow slopes was the area where had the the rich species among all the physiographic location. 5. As species diversity(H´) and evenness(J´) were the most high value in slow slopes and the most low one in ridge parts, it were closely related to the degree of inclination of slope, and dominance(1­J´) were the high value in glen parts.

This study is to reveal problems of forest development, present environmental ethics against various activities disturbing forest ecosystems, and provide fundamental view for sustainable developmental policies of forest in Korea. In forest conversion to other uses in Korea, one-agricultural sectors are occupying large proportions, and the tendency of unsustainable development is appearing. Sustainability in the forestry sector is divided into that of forest resources and forest ecosystems, and, thus, how to introduce development methods that support the original forms of forest ecosystems and bring up as economic forest is linked to the future of forest in Korea. Golf courses and ski resorts are considered as ‘wrong’from the ethical view of the land ethics by Aldo Leopold because they do not contribute to integrity, security, beauty of biotic community of forest, and, thus, foresters need to express the clear standpoint and attitude against them. Reforestation in forested area is discrepant from the principles of land ethics and economic loic, forest plantation are presented as an alternative plan for maintaining of sustainability of forest plantation are presented as an alternative plan for maintaining of sustainability of forest resources. Foresters cannot pose a problem to livestock industry unless it converts forests to pastures, but views of animal liberation and animal right have ethical validity, and vegetarianism as personal ethics of forester has practical meanings of environmental preservation as we consider impacts of livestock industry on forest ecosystems. View of the animal right against hunting and poaching has ethically persuasive power than that of ecocentricism. With considering the present situation of forest ecosystem in our country, preclusion of poaching and illegal gathering rather than promotion of hunting accords with forester’s proper task. Approach to forest development should vary with main conditions of forest ecosystems. Strictly regulation for managing developmental projects that cause large­scale physical transformation and deny ontological value of forest are ot breaking the principles of free market economy, but are restoring a justice ethically for sustainable development.

This study was carried out to look back over the agricultural history and to consider various forms and developmental stages of agriculture, and to provide the fundamental information for sustainable agriculture in the future. The results are as follows: 1. Human has establshed villages to gather systematically more stable foods with more milder climate since last glacial period, and then human was faced with food ploblems and prefered agriculture as a new adaptation behavior, accumulating the same environmental and cultural experiences. 2. Agriculture were subdivided into wheat and barley millets(or miscellaneous cereals)ㆍpaddy riceㆍtuber ones by major cultured crops, and the origin and choise of major crops were depanded on the period for its early distribution and the climatic niche of them. 3. While wheat and barley agriculture were apread out centering around fertile crescent and its outskirts, paddy rice and new world agriculture have progressed with different pathways. 4.Reasons that agriculture in Korea were begun more lately than other agricultural regions were attributed to geopolitical location, very rich hunt-gathering resources, strong hunter-gatherer nature of inhabitants at that time, environmental and climatic conditions, and absence of major culturing crops in this region. 5. Early agriculture in Korea had a tendancy of miscellaneous cereals agriculture, and this agriculture has developed with a relation to Chinese one. 6. Crops of the new world were greatly contributed to famine relief and food multiplicity for human beings.

컴퓨터 소프트웨어 저작권 보호에 대한 일반인식과 지적재산권 법제도의 개선방향

이성섭,윤종욱,황동주 한국중소기업학회 2002 中小企業硏究 Vol.24 No.1

우리나라는 컴퓨터 소프트웨어(S/W) 지적재산권 보호제도에서 아직 개발도상국의 수준을 벗어나지 못하고 있다. 인터넷 서베이를 통한 S/W 사용자와 공급자를 대상으로 한 조사는 이들이 현행 지적재산권 보호제도의 문제점에 대하여 매우 비판적 시각을 가지고 있음을 보여주고 있다. 그리고 현행제도가 지적재산권 자산가치를 보호하는데 보다 적합한 민사적 방식으로 변화되어야 함을 지적하고 있다. In this research, an internet survey was conducted to collect information on the perception of computer software users and suppliers on the intellectual property right in computer software. The survey information reveals their critical view against the problems in current legal institutions of intellectual property right. Privy filing requirement for the indictment against infringement on intellectual property right is the dual-charactered institution. Its meritorious point is the ensured securement of property of intellectual property right holder when a case of property right infringement is apprehended. The weakness of current legal institution is the reliance on the criminal procedure in law enforcement. Current privy filing requirement system contains incentive effect to encourage illegal piracy. High piracy rate in Korea despite public sentiment against illegal infringement on intellectual property right seems to indicate the unfulfilled improvement of legal institution to protect intellectual property right up to the level of public awareness. Attention is called for efforts to make steps forward from negative stance of staging anti-piracy campaign to more active stance to change legal institutional environment and rely more on civil lawsuit litigation, which enables more responsive protection of intellectual property right accordingly to property value.

이윤원,이민순,윤상욱,김진수 中部大學校 自然科學硏究所 1999 自然科學硏究論文集 Vol.8 No.1

수락계곡에 있어서 산록시면 하부의 이치림의 군락구조에 대한 속성을 조사한 결과 다음과 같이 요약할 수 있다. 1. 본 군락은 54종의 식생으로 구성되었는데 교목층은 참나무류가 우점하고 있으며, 아교목층 저목층으로 내려갈수록 서어나무 신갈나무의 중요치가 높아지고, 초본층에서도 서어나무 물푸레나무 치묘가 많이 발생하고 있으므로 굴참나무가 우점하는 군락에서 신갈나무, 서어나무 군락으로 천이 cycle이 진행중인 것으로 판단된다. 2. 군락전체의 종다양도는 1.5452로 높았으나, 교목층의 종다양도는 낮았고, 종내경쟁이 심하였으며, 종간경쟁은 초본층이 가장 심하였다. 또한 저목층에서 안정도가 가장 높게 나타났으며, nich breadth는 초본층이 가장 높게 나타나는 것을 볼 때 초본층에서 교목층까지 차례로 생태적 지위가 재편성되는 과정으로 판단된다. 3. 수고 분포도와 흉고직경급 분포도를 토대로 군락동태를 예측해본 결과 천이 초기종인 굴참나무, 갈참나무가 교목층에 우점하는 군락에서, 천이 후기종인 신갈나무, 서어나무가 침입하여 천이가 진행중인 군락으로 판단된다. This research was aimed at figuring out the characteristics of community structre of secondary forest ecotone of deciduous broad leaved trees in foot slope of Wolsobong area, Which valley and foot slope and hill side doing net crossed. It can be expected to provide the fundamental data for tending and natural regeneration of broad leaved forest, in the Mt. Daedun as being known as temperature middle zone. The results are such as follows: The vegetation of the secondary forest ecotone, which foot slpoe and hill side being crossed, was composed of 54 species, the canopy domineted species, Quercus spp., for example. And under story, shurb layer was going lower, dominance species were Carpinus laxiflora, Quercus monglica. So it might be said that the investigated area is doing succession at the present time. Species diversity appeared 1.5452 at high values. Therefore the investigated area is reflecting species composition by environmental factors. On the other hand, at the each layer level, species diversity of the upper layer was lower values and interspecific encounter of herb layer the highest. And it may be concluded that niche breadth does appeared reforming, due to the stability of shurb layer strong of intraspecific encounter. Through analyzing dynamics of the community with using data, height distribution and D.B.H. class distribution range, Quercus variabilis, Quercus aliena species were rapidly growing well adapting. Afterwards it is assessed that the community structure of researched area will be obviously devoloped climax such as dominated Quercus monglica or Carpinus laxiflora community.
