This study was conducted to clarified the relationship between bird community and forest structure and present the counterplan for protection and management of bird community from February 1993 to July 1995 at deciduous and coniferous forest within Mt. Nam area, Seoul, Korea. DBH distribution has not significant differences in each study site. Deciduous forest had more foliage coverage in all layers than coniferous forest. Total 41 species of birds, which were 16 species of resident, 14 species of summer visitor, 4 species of winter visitor, and 7 species of passage migrant were recrded in two study sites. Leaf use rate of birds was increased the increase of coverage. The number of breeding species and pairs, breeding density, and diversity index were greater in deciduous forest than coniferous forest. The number of species and pairs on bush-nesting and foraging guild were greater than other guilds. And the nuber of species and pairs on hole nesting guild were the fewest in nesting guild. Use rate of artificial nests for improvement of habitat quality was greater in coniferous forest than deciduous forest. Maintenance of bush layer, increase of coverage and leaf layer diversity, supply of artificial nests, management of large trees, and control of natural enemy were necessary for protection and management of bird community in Mt. nam area.

After the IMF financial crisis, a lot of risks in construction industry have been increased gradually with the expansion of construction industry widely, higher stories of building, and the expansion of the underground space and excavation work. These risks are bringing out construction accidents such as the death, the injury of worker and so on, not so much as it would be effected the corporation's image. In spite of these situations, many construction industries still maintain the wrong methods and not try to decrease construction accidents. Recently, we should focus on the fact that management system of the larger construction also is being good, on the other hand, the condition of the work in the case of smaller construction industries is very poor, construction company have a particular safety management system but it has a difference according to the construction magnitude, construction companies have a particular safety management system but it has a difference depending on the construction according to the construction magnitude. Therefore, this study will suggest the developed way of construction safety management by the comparison and analysis from the difference between the higher and the smaller construction industries.

Construction work accidents have not decreased in spite of much effect such as new work methods education and research related to the safety management. Specially, many fatal accidents were mainly caused by unanticipated risk factors in reinforced concrete construction work, which was involved in apartment, building. school church, hotel hospital, bank work and the other works. According to the construction fatal accident book by KOSHA 1,903 workers were killed by the fatal accidents in reinforced concrete construction work during the 13 years$(1992\~2004)$. From these reasons, this study researched the cause of fatal accidents which were happened in reinforced concrete construction work during last 13 years and surveyed construction managers and specialists about risk factors according to the work type in the reinforced concrete construction work. Therefore, this study will suggest the counterplan about the construction safety management and prevent fatal accidents from construction site related to the reinforced concrete construction work.

본 연구에서는 가뭄지수를 간단하고, 신뢰성 있고 그리고 쉽게 구할 수 있는 방법을 제안함으로써, 가뭄식 도시지역의 생활용수 및 공업용수의 부족에 대비한 용수수급대책 마련에 이용할 수 있도록 하였다. 가뭄지수 산정은 Phillips 가뭄지수법을 이용하였다. Phillips 가뭄지수법은 월강수량의 초과확률에 근거를 두지만, 실시간 현 가뭄 상황을 파악할 필요가 있을 경우 일강수량자료를 이용할 수 있어 실용성이 아주 컸다. 적용성 검토를 위해 주요 공업지역인 울산시와 포항시의 생활용수 수급체계를 이용하였으며, 그 우수성이 확인되었다. 따라서 본 연구성과는 다른 도시 지역에서의 비상가뭄대책 수립에도 매우 유용한 방법으로 사용될 수 있다.

변산반도국립공원에서의 귀화식물은 24과 65속 83종 3변종 2품종으로 총 88종류가 확인되었다. 조사된 귀화식물을 유형별로 구분해보면, 생활형에는 1년생 초본이 38종류(43.2%)로 가장 많았으며, 그 다음으로 다년생 초본이 28종류(31.8%), 2년생 초본이 19종류(21.6%)로 구분되었다. 또한 목본 중 교목에는 아까시나무와 가죽나무가, 관목에는 족제비싸리가 확인되었다. 원산지별로는 유럽에서 이입된 종류가 26종류(37.1%)로 가장 많이 확인되었으며, 그 다음으로 북아메리카에서 이입된 종류가 23종류(32.8%)로 구분되었다. 또한 귀화도별로는 귀화도 3의 귀화식물이 28종류(31.8%)로 가장 높게 나타났으며, 귀화도 1의 귀화식물이 8종류(9.1%)로 가장 낮게 분석되었다. 이입시기별로는 이입 1기가 39종류(44.3%)로 가장 높게 나타났으며, 이입 2기가 16종류(18.2%)로 가장 낮게 분석되었다. 귀화식물 271종류에 대한 본 연구대상지의 도시화지수는 32.5%로 분석되었으며, 생태계교란야생식물인 돼지풀이 확인되었다. 돼지풀은 꽃가루 알레르기를 일으켜 인체에 피해를 주는 식물로서 변산반도국립공원 전 지역에 침입하여 분포하였다. 따라서 이에 대한 장기적인 모니터링을 통한 지속적인 관리대책이 필요하며, 이입된 귀화식물의 생태적인 특성을 파악하고 체계적인 관리방안이 요구된다.

The purpose of this study is to provide basic data for establishment of prevention counterplan against construction accidents in preparation for variation of climate conditions. In order to execution of this study, it was analyzed relations of climate factors and cases of construction accident occurred construction sites. In occurrence of construction accidents inducing death upon variation of Climate factors, precipitation and wind velocity were not related directly to construction accidents inducing death. On the other hand, the more temperature and humidity are high, the more construction accidents inducing death occurred. Especially, when temperature and humidity are above $24^{\circ}C,\;70\%$ respectively, field managers must pay attention to safety management of construction sites.

After the legal foundation for the Total Load Control System (TLCS) process is embedded in integrated water management counterplan for 4 major river basins (1998), Kyunggido Kwangju City prepared the implementation plan of TLCS at first time. There is little difference between TLCS and TMDL(Total Daily Maxium Loading; U.S.A). TMDL is applied only when mandatory effluent limitations are not stringent enough to attain any water quality standard. But object of TLCS not only attain water quality standard at distributed watershed but also consider development of area at non-distributed watershed. For applying of systematic and consistent TLCS, we need to establish a system integrated watershed and point source, non-point source and assessed massive database easily. Now we are study on applicable possibility of BASINS on Korea, we think that BASINS's tool and many models are more easily apply to TLCS, so we recommend TLCS will be applied using BASINS.

Recently, construction work's tendency has become a high-rise building, a complexity and a large size. According to the KOSHA data, construction work accidents have not been decreased. Looking at from the side of accident accidents of construction industry are occupied over 1/3 among all industry accidents. Therefore, this study will analyze the accident of the building construction work from the data of KOSHA which were collected during 11 years$(1992\~2002)$ data relating to serious accidents of the building construction work suggest the counterplan according to the each work type in building construction work.

CCS(Carbon Dioxide Capture and Storage) is considered as the most effective counterplan in the mitigation of climate change. Even though the risk of leakage of $CO_2$ stored in the geologic formation is very low, the public is expected to disagree with the initiation of a CCS project without proper management plans ensuring the safety. In this study, recognition of laypeople were surveyed about CCS, climate change, characteristics of carbon dioxide, storage concepts, ground pressure, the impact of carbon dioxide, and carbon dioxide for leakage. Thereafter the factors that could affect to recognition of CCS were analyzed by regression analysis. A survey was carried out to find out the public understanding and awareness about climate change and CCS. It is the purpose of this study to propose appropriate risk management strategies based on the findings from the survey.
