  • 항내로 침입하는 특정 주파수대의 파랑을 제어할 목적으로 파랑필터이론에 근거한 공진장치가 고안된 이후, 선박의 장주기운동을 제어하기 위하여 미국 Long Beach 항 J-부두와 이탈리아 로마 요트항 등지의 실해역에 공진장치가 적용된 사례가 보고되어 있다. 최근, 초장주기파 혹은 고립파로 근사된 지진해일파의 제어에 관한 공진장치의 유용성과 적용성은 확인되어 있지만, 실해역에서의 지진해일파를 대상으로 한 검토는 보고된 사례가 없다. 본 연구에서는 우리나라 동해안에 위치한 묵호항과 임원항에 기개발된 형상의 공진장치를 적용하여 1983년 동해중부지진해일과 1993년 북해도남서외해지진해일의 작용 하에 항내에서 지진해일고의 저감율을 COMCOT 모델에 의한 수치해석으로부터 검토하였다. 결과에 따르면 묵호항에서는 최대 40%~50% 정도, 임원항에서는 최대 21% 정도의 저감율을 각각 나타내었으며, 이로부터 실해역의 지진해일파에 대해서도 공진장치의 유용성을 확인할 수 있었다. 또한, 최적의 공진장치를 얻기 위해서는 현장 여건 등을 고려하여 공진장치의 형상, 배치 및 크기에 관해 다각도로 검토될 필요가 있는 것으로 판단된다.

  • The object of this study is to suggest some alternatives for environmental management towards sustainable urban development of Chongju city in Korea. This study analyses urban environmental indicators (population density, land use, road, park, car, etc.), level of air and water pollution and solids waste generation by comparing Chongju city and other large cities. Some alternatives towards sustainable development in Chongju city would be summerized and suggested as higher concentrated land use(compact city), mixed land use, supply of mass transit, establishment of regional environmental standards, total emission regulation of air and water pollutants, the preparation of Local Agenda21 of Chongju, and the introduction of strategic environmental assessment(SEA) into environmental impact assessment.

  • After laws for recycling promotion of construction wastes was established on December, 2003, successive technical and institutional measures related to construction wastes are driven. Typically quality standards for recycled aggregate were enacted and officially announced, and recently the quality assurance system for recycled aggregate is promoted to be established. In relation, this study reviewed major factors affecting certification examination necessary to carry out quality assurance system for recycled aggregate and related standards to guarantee the quality of recycled aggregate. More specifically it is suggested that working place examination related to manufacturing facility and planning, quality control manpower and system, environmental and safety control, etc, and quality inspection with classified by for road construction, for concrete, and for asphalt concrete are used as quality assurance standards.

  • A thematic land cover map of Pusan port area was developed using Landsat satellite TM(Thematic Mapper) image. Two types of digital data which are road and sea water layer are extracted from existing paper map were overlayed over the developed land cover map. SPIN-2(KNR-1000) image was utilized to make a facility map of JaSungDae port. SPIN-2 image, which has a cell resolution of 1.56 m showed higer accuracy than TM image, which has a cell resolution of 30 m for facility mapping. Overall, the techniques of digital mapping using satellite image are very useful, effective and efficient.

  • Port, one of nation's key infrastructures, is a point of road and sea transports meeting. As a key base of inter-modal transportation systems, the port is of ever increasing importance for realizing nation's vision of making Korea as an economic and logistics hub in the Northeast Asia. At present, Korean ports handle 99.7% of gross trade volumes in Korea, which requires considerable attention on its safety issues. However, due to the critical characteristics of the port and insufficient attention paid to it, the port industry meets more disasters compared to other industries. Therefore, this paper tries to analyze the disasters happened at the port to have better understanding on its reasons, further to use as learned lessons to prevent from potential disasters that may arise at the port.

  • Road and maritime transport which connecting main cities in the world is already fully saturated, and the loss cost caused by recent high oil prices is getting bigger. Transportation by inland waterway is rising as an alternative method of them. Concerning this, the GI Waterway is on construction to connect the Yellow sea and Seoul. Nevertheless, there are no existing aids to navigation around the area and no studies have been carried out for them. As the construction progresses, installation of proper aids to navigation should be considered and profound studies need to be carried out. This study focused on introduction of the cases and the systems of other countries inland waterway aids to navigation and suggested a suitable navigation aids system along the inland waterways in Korea and a way of installation for that system.

  • South Korea and Mongolia are both the member countries of the World Trade Organization, but neither was the country with FTA. Nowadays, South Korea widely concludes the FTA with other countries, and the trade area has extended toward the neighboring continents and seas. Mongolia is a country with smallest economic entity but large in area and with abundant underground resources. And it's a main strategic zone of Eurasia. After the disintegration of the Soviet Union, Mongolia began to turn to market economy, and eagerly made effort to open and reform. With the expanse of trade and economy cooperation between South Korea and Mongolia, Mongolia started its sea road expanding. And the south Korea went to inland to get the necessary resources. Both of them feed its needs and obtain its profits.

  • ODA projects such as multi-purpose dam, industrial complex, road construction etc. have resulted in environmental damage and resident relocation including destruction of site of living. Even the grandiose developments as ODA projects have made clear the value clashes between development and environmental conservation, and have brought about conflicts between public interests and public environmental right, and the discordance between public interests and private property rights in the recipient country. This study summarizes and analyses the Korea's ODA projects and will suggest the public participation and governance system based on Saemaul Movement, Strategic Environmental Assessment and Environmental Impact Assessment based on the guideline of OECD DAC, and emphasize Strategic Environmental Assessment and Social Impact Assessment in the procedure of ODA projects. In the future the ODA project should be implemented for the overcome of poverty and response to climate change based on the experience and trial and errors of Korea's compact growth and past ODA projects.

  • The safety degree of navigation for collision avoidance is closely related with the combination between mariner's behavior and navigational environment. The condition of navigational environment is mainly decided by navigable waters, ship traffic, rule of road, sea state, weather and so on. Especially, the condition of navigable waters and ship traffic in navigational environment are ones of the important factors to attain safe navigation when mariners are underway and crossing, head on or overtaking situation. Thus this paper is to analyze the characteristics of mariner's behavior for collision avoidance caused by ship traffic and navigable waters by analyzing the contents of questionnaire and the results of international collaborative research. As a result, it can be concluded that the density of ship traffic and the area of navigable waters affect mariner's ship handling for collision avoidance.
