  • This study attempts to establish a system extracting and monitoring cultural grounds of seaweeds (lavers, brown seaweeds and seaweed fulvescens) and abalone on the basis of both KOMPSAT-2 and Terrasar-X data. The study areas are located in the northwest and southwest coast of South Korea, famous for coastal cultural grounds. The northwest site is in a high tidal range area (on the average, 6.1 min Asan Bay) and has laver cultural grounds for the most. An semi-automatic detection system of laver facilities is described and assessed for spacebome optic images. On the other hand, the southwest cost is most famous for seaweeds. Aquaculture facilities, which cover extensive portions of this area, can be subdivided into three major groups: brown seaweeds, capsosiphon fulvescens and abalone farms. The study is based on interpretation of optic and SAR satellite data and a detailed image analysis procedure is described here. On May 25 and June 2, 2008 the TerraSAR-X radar satellite took some images of the area. SAR data are unique for mapping those farms. In case of abalone farms, the backscatters from surrounding dykes allows for recognition and separation of abalone ponds from all other water-covered surfaces. But identification of seaweeds such as laver, brown seaweeds and seaweed fulvescens depends on the dampening effect due to the presence of the facilities and is a complex task because objects that resemble seaweeds frequently occur, particularly in low wind or tidal conditions. Lastly, fusion of SAR and optic spatial images is tested to enhance the detection of aquaculture facilities by using the panchromatic image with spatial resolution 1 meter and the corresponding multi-spectral, with spatial resolution 4 meters and 4 spectrum bands, from KOMPSAT-2. The mapping accuracy achieved for farms will be estimated and discussed after field verification of preliminary results.

  • Recently, deep ocean water (DOW), which is plentiful in the East sea, has been recognized a global resources for 21st century. To develop DOW resource of 300m deep at Gosung sea, the pipeline of about 4 km long is essentially required to establish land based model complex of DOWA techno-park at coastal zone. This study aims to establish design procedure of DOW supplying and utilizing systems, and to complete basic design of every major facilities. To design, various numerical analysis and engineering consideration have been studied by cooperative works for practical use.

  • 항만 리모델링을 위한 콘크리트 시설물에 대한 평가가 필요하며, 특히 리모델링이 결정된 경우에는 소파 블럭이나 케이슨 블록 등에 대한 재활용 여부를 평가하여 재활용이 가능할 경우에는 유용하는 것이 경제적인 리모델링에 도움이 될 수 있다. 이 연구에서는 콘크리트 항만시설물에 대한 건전성 평가 및 재활용성 평가를 위하여 기존의 초음파 속도법을 비롯하여 슈미트 해머를 이용한 반발경도법, 충격반향법, 표면파 속도법 등의 비파괴시험을 실시하였다. 국내 5개 항만에 대하여 비파괴시험 및 시편을 채취하였으며, 채취한 시편에 대한 압축강도 시험을 수행하여 비파괴시험 결과와 비교하였다. 비파괴시험결과와 압축강도 시험을 통하여 콘크리트 재료의 탄성계수와 압축강도 등을 평가하였다.

  • The EXPO Ocean Park in Yeosu has taken on the apsect of a theme park and has specialized facilities. But the outdoor circulation system that has been used by Expo 2012 Yeosu Korea still remained. These conditions can occur unused circulation and a long walk between facilities. The Purpose of this study is to suggest the improvement of circulation system that uses walking and outdoor space at the Expo Ocean Park in Yeosu. The following researches are drawn based upon the purpose. First, Definition and existing academic literature of theme park is considered. Second, the type, utilization condition, and circulation of outdoor facilities of Expo Ocean Park are investigated through the field survey and analysis. The field survey is conducted on the Expo Ocean Park in Yeosu for five times from October. 2013 to March. 2014. The data is collected through the photographed outdoor park and interviewing the staff of 2012 Yeosu World Expo Foundation. Third, the case study on outdoor circulation of waterside park and park with amusement facilities that are similar to Expo Ocean Park are examined. The result of this study is expected to seek sustainable management of Expo Ocean Park for maximizing local resident and visitors' satisfaction and improving effective park image. Since the field survey was conducted before the park is reopened and The Expo Ocean Park is on the improve through the this study at present, the verification of improvement scheme based on Post-Occupancy Evaluation(POE) is needed for future study.

  • 본 연구에서는 바다낚시인의 증가 따른 낚시시설의 부족을 해결하고 바다낚시를 해양레저로 정착시키며 어촌의 경제 활성화를 돕기 위한 목적으로 조성된 바다낚시공원의 시설측면의 문제점을 실증적으로 파악하고, 이 결과를 바탕으로 바다낚시공원의 시설개선사항 및 새로운 바다낚시공원의 계획을 위한 시설계획방향을 제시하였다. 시설측면의 문제점 분석을 위하여 현재 운영 중인 9군데 바다낚시공원과 2군대 바다목장을 대상으로 시설운영 현황조사 및 시설관리인 인터뷰조사를 실시하고 바다낚시공원, 어촌체험마을 등 25군데 바다낚시시설에서 낚시인을 대상으로 시설요구사항에 대해 설문조사를 실시하였다. 조사결과 가족단위 낚시인구의 증가에 따른 안전시설 및 화장실, 휴게시설 등의 편의시설 확충에 대한 요구가 많았으며, 초보자를 위한 가두리낚시터 등의 교육, 체험시설의 필요성과 캠핑장, 해변공원, 산책로 등의 낚시활동 외 여가활동을 위한 시설 도입에 대한 요구가 높게 조사 되었다. 따라서 바다낚시공원은 낚시활동을 중심으로 한 복합레저공간으로 계획하여야 하며, 낚시공원 내 활동요구사항에 적합한 시설구성 및 시설계획이 필요하다.

  • 유럽 및 일본에서 건설되고 있는 폐쇄처분장(CDF)은 오염 준설물의 처분을 위해 세계적으로 널리 사용되는 방법으로 주변 환경과 생태계에 미치는 영향을 최소화하면서 오염 준설물을 차단하기 위한 시설이다. 폐쇄처분장의 개념은 간단하지만 이를 건설하는 것은 쉬운 것이 아니다. 폐쇄처분장(CDF) 시설을 계획하는 과정에서 토목공학, 조경, 화학, 입법, 사회적 영향, 환경공학과 같은 다양한 분야에 대한 전문지식과 기술이 고려되어야 한다. 본 고에서는 CDF의 일반적인 지침에 대해 간략히 소개하였다.

  • Despite technological developments and application advances of Acoustic Doppler Current Profilers (ADCPs), no standard procedure has been adopted or accepted for calibration of ADCPs. Limitations of existing facilities for calibrating ADCPs, the complexity of ADCP instruments, and rapid changes in ADCP technology are some of the reasons why a standard procedure has not been adopted. However, there is increasing realization of the need for effective Quality Assurance (QA) and as part of that the importance of standardized calibration. In this study, the significance of calibration and QA plans for ADCPs is discussed and the calibration facilities for ADCPs at home and abroad are reported. Furthermore, the method for calibrating ADCPs using a towed car and its limitations are discussed. This study contributes to discussions surrounding the establishment of standard procedures for calibrating ADCPs and QA plans, and the construction of calibration facilities in the future.

  • The purpose of this research is to grasp the present state of marine lifelong education and to provide direction for maritime industry. In this research, we first saw our country present ocean industry and the ocean lifelong education concept and definition besides formal school education to secure ocean human capital. Second, we researched about the ocean lifelong education that has been progressing by the organization, and by this, we inferred what to improve from our country ocean lifelong education. As a result, the improvement point for present ocean lifelong education of our country was first, the reflect of variety of marine related information in our country lifelong education is low, second, the learners were mostly children and teenagers, third, most of the were event education. Forth, it is good that there are a lot of experimenting programs, but most of them were experiment of ocean leisure sports and visiting the facilities, and because these are one-time thing so it was hard to secure marine citizenship or help them set their career in marine. Fifth, all facilities had similar contents for the experimenting program, and sixth, education period was concentrated on May and November.
