  • 홍수와 가뭄의 증가, 수질악화, 물부족 등 물 문제 해결을 위한 대안으로 통합수자원관리에 대한 논의가 국제사회에서 활발하게 진행되고 있다. 국내에서도 많은 학자들이 수자원관리를 위한 새로운 대안으로 통합수자원관리를 주장하고 있지만, 추상적인 설명이 대부분이다. 따라서 본 연구는 통합수자원관리에 대한 정의, 원칙, 추진전략 등을 정리하여 통합수자원관리에 대한 종합적이고 체계적인 정보를 제공하고자 한다. 본 연구는 다음과 같은 흐름을 갖는다. 첫째, 수자원관리를 위한 새로운 대안으로 통합수자원관리가 등장하게 된 배경을 살펴보았다. 물문제를 해결하기 위해서는 연속적이고 상호작용하는 하나의 '시스템(係)'으로 수자원을 인식하고 관리해야 한다는 주장이 확산되고 있으며, 통합수자원관리가 그러한 인식을 갖고 있는 대안으로 등장하였다. 둘째, 통합수자원관리의 정의, 원칙 등을 조사하였다. 통합수자원관리는 자연의 지속가능성을 훼손하지 않으면서 경제적, 사회적 복지를 최대화하기 위하여 물, 토지 및 관련 자원의 조화로운 개발을 위한 과정으로 정의된다. 이러한 통합수자원관리를 위한 원칙으로는 지속가능한 수자원의 개발, 이용 및 관리원칙, 물순환 체계 고려 및 유역관리원칙, 이해당사자 참여 및 조정의 원칙, 비용부담 및 편익 균형배분의 원칙 등이 있다. 셋째, 통합수자원관리를 위한 추진방안을 제시하였다. 법제도 정비 및 부문별 통합관리강화, 수자원 관련 자료의 신뢰도 제고 및 의사결정 체계 구축, 관련계획과의 연계, 계획-실행-평가의 순환구축, 물관리 비용부담체계 구축 등이 통합수자원관리의 실행을 앞당길 수 있을 것이다. 본 연구는 통합수자원관리에 대하여 종합적인 정보를 제공하고 개선을 위한 추진방안을 제시하여 국내 수자원관리의 문제해결을 위한 기반을 구축하는 데에 기여할 것으로 기대된다. 범람범위의 1차적인 정보에서 수립할 수 있었던 계획이 가질 수 있었던 한계점을 좀 더 향상된 정보를 이용하여 극복함으로써 효율적이고 체계적인 치수 방재 계획수립이 가능할 것으로 판단된다.group) 67개, 속(family) 161개로 분류되었으며, 가장 저차단위인 통(series)이 390개 분류되었다. 또한 작물이용측면에서 실용적 분류를 실시하였는데, 논토양의 경우 보통논, 미숙논, 사질논, 습논, 염해논, 특이산성논으로 분류할 경우 각각의 분포면적이 31.9%, 23.0%, 31.9%, 9.1%, 3.9%, 0.2%이었다. 밭토양의 경우에도 보통밭, 사질밭, 미숙밭, 중점밭, 고원밭, 화산회밭으로 6개 유형으로 분류할 경우 각각의 분포면적은 41.9%, 23.3%, 17.5%, 13.9%, 1.1. 2.2% 이었다. 도시화 및 도로확대 등 다양한 토지이용 및 지형개변으로 과거의 토양정보가 많이 변경되었다. 그래서, 앞으로는 인공위성자료 및 항공사진을 이용하여 빠르고 쉽게 활용할 수 있는 토양조사 방법개발과 기 구축된 토양도의 수정, 보완 작업이 필요한 절실히 요구되고 있는 현실이다.브로 출시에 따른 마케팅 및 고객관리와 관련된 시사점을 논의한다.는 교합면에서 2, 3, 4군이 1군에 비해 변연적합도가 높았으며 (p < 0.05), 인접면과 치은면에서는 군간 유의차를 보이지 않았다 이번 연구를 통하여 복합레진을 간헐적 광중합시킴으로써 변연적합도가 향상될 수 있음을 알 수 있었다.시장에 비해 주가가 비교적 안정적인 수준을 유지해 왔다고 볼 수 있다.36.4%)와 외식을 선호(29.1%)${\lrcorner}$ 하기 때문에 패스트푸드를 이용하게 된 것으로 응답 하였으며, 남 여 대학생간에는 유의한 차이(p<0.05)가 인정되었다. 응답자의 체형은 ${\

  • Road development is considered an important factor in invasion and dispersion of ailen plants by damaging the natural ecosystems and connecting the detached landscapes into long tubular structures. In this study, vegetation survey was carried out according to the topographical characteristics of cut slope, fill slope, and flat land at the construction site in order to understand the effect of road developemt on the change of the floristic composition of ailen plants. Road developement projects caused a lot of changes in annual and biennial alien plants because of continuous disturbances. Changes in species composition of alien plants decreased in the cut slope. On the other hand, the ailen palnts of the fill slope increased. The increase or decrease alien plants on flat land were identified depending on where it occurred, and no major trend was found. The cause of these change was driven by unintentionally introduced alien plants. In particular, the cut slope with a high occurence of unintentional ailen plants should not be used as a source of high-risk alien plants such as ecosystem disturbances. Since the transplanted species were intentionally planted by the landscape plan, it was possible to identify colonies from early stages and spread to the nearby flat land. Therefore, in order to minimize the impact of road slope vegetation on the surrounding ecosystem during and after road construction, it is suggested to plant high viability plants in the landscape design during the environmental impact assessment consultation.

  • 국토의 효율적 이용과 여가공간의 개발에 있어서 산악지형의 개발 잠재력은 무궁무진하다고 볼 수 있다. 그간에 산악지형의 개발은 관광자원으로서의 활용이라는 견지에서 무분별한 개발과 자연환경 훼손을 방치해왔던 것이 사실이다. 산악지형의 관광자원 활용은 그 범위에 있어서나 방법에 있어서 매우 다양한 방식을 채택할 수 있다. 한국의 산이 보유하고 있는 자연경관과 문화유적이 접목된 명산사찰을 활용한 문화관광, 자연자원의 보존과 경제 개발, 도시민의 위락 여가공간 제공이라는 세 가지 목적을 동시에 충족시킬 수 있는 산악형 자연공원, 동계스포츠 활동을 위한 스키리조트의 개발과 이용, 마지막으로 산악지형의 경제 발전을 위한 대체산업 육성이라는 취지 하에 등장한 산지 카지노리조트 등 사회, 문화, 경제, 보건, 오락 등 산지는 그 효용성을 날로 더해가고 있다. 산은 더 이상 인간과 격리된 공간이 아니라, 인간의 생활 공간이자 휴식공간이며, 다양한 여가행위를 위한 공간이다. 유럽 등 구미 관광 선진국에서는 이미 산악지형 고유의 경제적, 사회적 중요성에 입각하여 공간의 효율적인 정비를 통해 합목적적이고 친환경적인 산악형 리조트 건설을 통해 지속적인 개발을 추진하고 있으며, 개발에 일부제약이 뒤따르기는 하지만, 관광개발을 위해서 환경보존을 필수적인 조건으로 인식하고 있다. 다시 말하면 관광개발과 환경보존은 불가분의 관계에 놓여있다는 것이다. 따라서 산이 우리에게 가져다주는 이로운 점을 생각할 때 인간의 지나친 개발욕구와 몰지각한 자원활용을 위한 관점에서 산을 보아서는 아니될 것이다. 산을 개발하고 정비하여 관광자원으로 활용할 때보다 친환경적인 시각으로 접근해야 하며, 우리의 산이 우리에게 돌려줄 것을 생각하기 보다 우리가 산에게 해주어야 할 것이 무엇인지를 먼저 생각한다면, 산은 우리에게 경제적 이득과 함께 우리의 여가생활을 위한 최적공간으로 다가설 것이다(요약 및 결론에서 발췌)는pocyanidin C-1-3'-3" -3.'S _0-trigallate는 100rM에서 70%의 강한 저해효과를 나타냈으며,epigallocatechin-(4$\beta$$\longrightarrow$8)-epigallo-catechin-(4$\beta$$\longrightarrow$8)-catechin는 51%의 저해효과를 나타내었다. 산업적응용을 위해 분획한 폴리페놀군은 미백효과 검증실험인 tyrosinase 저해율 측정평가에서 폴리페놀 함량이 가장 높은 Fraction 111의 경우 Sooppm에서 74.2%의 높은 저해율을 나타내었다. 항산화력 실험에서는500pw1이상에서 강한 활성능을 보인 SOD 유사활성능을 제외한 나머지 DPPH와 xanthine oxidase 저해효과에서는 Fraction II와III 모두가50ppm이상에서 80% 이상의 높은 유리라디칼 소거능력을 나타내었다. 그리고 각 Fraction별 항균력 측정 결과 Fraction 르와 111이 우수하게 나타났고 항균활성은 그람음성균보다 그람양성균에서 효과적이었으며, 농도별 항균력시험 결과 농도가 증가할수록 비례하여 저해율도 증가함을 알 수 있었다. 첨가농도를 달리하여 미생물의 생육도를 측정한 결과, fraction II磎꼭\ulcorner경우 그람양성균에 대해 500 ppm 이상에서 뚜렷한 증식억제효과를 나타내었다.서 뚜렷한 증식억제효과를 나타내었다.min/+}$계 수컷 이형접합체 형질전환 마우스에 AIN-76A 정제사료만을 투여한 대조군은 1.40$\pm$0.24(100%)에 비하여 I3C 저농도 투여 실험군(Group 1; 0.85$\pm$0.23; 61%, P<0.01), 그리고 I3C 고농도 투여 실험군(Group 2 ; 1.32$\pm$0.2

  • A plant diversity, which consists of indigenous plant community with Orientla thuja community (Natural monument no. 1) in Dodong, Daegu, is identified and analyzed as ecological characteristic to consider worth plants and vegetation resource of the region. The vascular plants of Thuja orientalis community were listed as 219 taxa (3.7% of all 4,881 taxa of Korean vascular plants); 67 families, 147 genera, 199 species, 16 varieties, and 4 forms. Vulnerable species (VU) and least concerned species (LC) were recorded based on IUCN standard; Koelretueria paniculata (VU), Thuja orientalis (LC), and Exochorda serratifolia (LC). Although the study site is a non-limestone area, a total of 15 taxa of calciphilous plants were identified; Cheilanthes argentea, Hypodematium glandulosopilosum, Asplenium retamuraria, Thuja orientalis, Spiraea blumei, Smilax sieboldii, etc. A total of 4 taxa endemic plants were identified; Prunus mandshurica for. barbinervis, Lespedeza maximowiczii var. tomentella, Forythia koreana (artificial origin), and Veronica pyrethrina. Among the list, 8 taxa of naturalized plants were identified; Fallopia dentatoalalta, Rumex crispus, Nasturtium officinale, Bidens frondosa, Erigeron annuus etc. Naturalization rate (NR) was 3.6%, of all 219 taxa of vascular plants and urbanization index (UI) was 2.2% of all 321 taxa of naturalized plants. Thuja orientalis occupies a lot of indigenous landscape in this study area which is the southern-limited part of a natural distribution where it can survive. The T. orientalis community, where indigenous plants have formed a characterful species composition based on habitat, has been confirmed as a worth national vegetation resource in an indigeous flora. It has been considered of plans for persistent conservation.

  • Traffic congestion in existing tunnels has increased due to increased traffic volume and enlarged vehicles. Enlarging existing tunnels has advantages over constructing new tunnels by reducing land purchasing costs as well as minimizing natural environment destruction. In fact, many overseas projects for enlarging existing tunnels have been reported. Thus, it appears that the demand on enlarging existing tunnels continues to rise in Korea in near future. Nonetheless, the studies related to the enlarged tunnels have been relatively rare since there have been few tunnel enlargement projects in Korea. In the present study, the tunnel behavior and the stability of rock pillar when enlarging existing parallel tunnels were investigated by performing FE analysis and using existing theory and empirical relationships. Four different enlarging cases, depending on the enlargement types and directions, were examined in the study. According to the results, for the tunnels with the same pillar width after enlarged, the uni-laterally enlarged tunnel indicated 5 to 20% higher crown settlement compared to the bi-laterally enlarged tunnel, and for the tunnel with the narrowest pillar, the highest shotcrete stress was observed. Also, the strength/stress ratio for rock pillar was more than 1.0 for all four enlargement cases, and the Matsuda's method was found to give higher strength/stress ratio by about 50% compared to the Peck's method.

  • The children's park, which was created uniformly during the industrialization period, is less utilized and is mainly used by the elderly during the day. In addition, sports facilities and rest facilities for the elderly are being installed, damaging the essence of children's parks. The main purpose of this study was to present the creation of a children's park that was appropriate to its essence and the utilization plan for the elderly. In this study, we conduct a survey to identify citizens' perception of children's parks and found that the opinions of children and the elderly were generally different. Children want to change and enjoy various games, while older people want to enjoy various programs while maintaining the status quo. As above, children do not dislike using the park with the elderly, but hope to create a separate park if possible. Meanwhile, the elderly want to renovate the current children's park and continue to use it. Therefore, in the future, some areas of children's parks will be created for the elderly or the entire area will be changed into small parks for the elderly, considering the location characteristics and population distribution of children's parks. In addition, the government should prepare measures for the introduction of programs for the elderly or maintenance using the elderly.

  • Actual vegetation map drown with the scale 1 to 100 and Alnus japonica population in Ja-neup and Woong-neup of the Mujechi moor were described in order to monitor long-termly and preserve permanently, where is a very rare Molinietea moor and a legally protected area. A total of 3036 plots of 5m $\times$ 5m were surveyed during summer 1996. Thiessen polygons of 1491 alder trees were derived from the plot data. Actual vegetation map was illustrated by 6 cover types such as needle spike-rush type, moor-grass type, alder-moor type, eulalia type, oak forest type, and exposed site. Molinia grasses native to the moor and Miscanthus grasses alien to the moor are reciprocally dominant. The area of Molinia grasslands was rapidly in decline and alder population size was dramatically in increase in the moor, particularly in Woong-neup. In Molinietea moor preservation more attention should be focused on the regulation of a nutrient rich soil from forest road and fire.

  • Due to habitat damage associated with climate change and human activities, biodiversity has decreased all over the world. In order to prevent further reduction in biodiversity, the international community has endeavored to establish a cooperative system, such as the Convention on Biological Diversity (CBD). Until now, most biodiversity strategic planning has been led by the national government. However, the National Biodiversity Strategy and Action Plan is conservative and its strategic plan is vague. Therefore, we propose a method for managing local biological resources called the Local Biodiversity Strategy and Action Plan. In order to provide the strategic plans and detailed plans for the Local Biodiversity Strategy and Action Plan, the report has examined several cases including Convention on Biological Diversity, Strategic Plan for Biodiversity 2011-2020, and the biodiversity strategies and action plans of the Republic of Korea and several other countries. As a result, the report demonstrates the survey and protection of bio-species, the designation and monitoring of conservation region, the management of the integrated eco-network, the establishment of biodiversity organizations and capacity building, the methods to promote networking and traditional knowledge, and the strategy for development in bioindustry. Consequently, the implementation of biodiversity management strategies by local governments will play a significant role in preserving and increasing biodiversity by realizing the goals of Strategic Plan for Biodiversity 2011-2020.
