This study is part of a project to develop and improve mooring systems for oceanographic use that include an electro-optical sensor, 1MHz Nortek Aquadopp Doppler Profiler and AIRMAR multipurpose Sensor. The adaption of Doppler current profilers to measure directional wave spectra has provided a new instrumentation approach to coastal and nearshore oceanographic studies. The HEIOB is developed are light weight and of a compact design, and can be easily installed in marine environment. Since there are no base station and gateways in marine environments, we selected CDMA and Orbcomm to send the data information. Therefore, the data can be sent by either e-mail service or Short Message Service (SMS). This paper will present some of scientific sensor results regarding real-time oceanographic and meteorological parameters such as wind spend, wind direction, wave direction, and etc. The modeling and test results highlight the engineering challenges associated with designing these systems for long lifetimes. It can also be used in future application to build wave observation buoy network in real-time using multiple ubiquitous buoys that share wave data and allow analysis of multipoint, multi-layer wave profiler.

인터넷, HDTV, VoD 등 통신 및 방송 수요의 증가에 따라 가입자망까지 광섬유를 포설하는 이른바 FTTH의 구현이 현실화되고 있다. 광가입자망 기술은 전달망과 가입자간을 연결하기 위한 전송(선로종단, 망종단) 장치와 전송매체 등의 설비로 구성되며, 고속 액세스 전송은 일반적으로 가입자에게 수 Mb/s 사용대역을 제공하는 기술을 말하는 것이다. 특히 가입자망에서 수백 Mb/s 이상의 가입자 사용 대역을 제공할 수 있는 것은 광통신 기술만이 가능하다. 세계적으로 광가입자망의 구축은 이미 2002년부터 시작되어 미국의 경우 SBC, Verizon을 중심으로 FTTx 서비스를 시작하여 2005년5월 현재 37개 주의 217곳에서 서비스가 진행중이며 일본의 경우 e-Japan Project로2007년까지 FTTH 천만 가입자를 목표로 2004년 말에 이미 200만 가입자를 돌파하는 등 광가입자망 분야에서는 세계적으로 가장 앞서가고 있는 실정이다. 한국의 경우전세계적으로 초고속 인터넷 보급률 1위로 기존의 VDSL에 의한 초고속 전송망이 이미 미국, 유럽 등의 광가입자망 대역폭과 근접한 속도를 보이고 있어 FTTH 구축은 오히려 늦어지고 있는 실정이다. 그러나 향후 방송/통신 융합 등 급격히 늘어날 대역폭요구를 수용하기 위해서는 광가입자(FTTH) 기술로의 전개가 필수적이고 이를 수용할수 있는 광가입자망 기술에 대해 살펴 본다.

Marine biotechnology is one of the promising frontier of scientific exploration and commercial utilization for the next century. Compared with the terrestrial environment, the oceans of the world remain largely unexplored and include a major portion of bio-resources. Using the tools of biotechnology, the vast and diverse marine resources can be applied to produce new products and foods. Marine biotechnology has the characteristics of pro-environment, saying energy, and intensive knowledge. Therefore, we can take advantage of the marine biotechnology industry under our situation with the poor natural resources. The study focuses on the current status and administrative supports on marine biotechnology industry for upgrading the economic value of output. The status of our marine biotechnology industry is beginning stage in the economic aspects. Manpower and the level of most technologies are weaker than the ones of the advanced countries. More investment and recruiting skilled specialists are necessary because the improvement of marine biotechnology is depend on the technology and scientists. This study suggests the ways of administrative supports for domestic marine biotechnology: Efficient information network and supporting system for the development of marine biotechnology should be interrelated with other technical and scientific fields; The government should provide sustainable fund for the long-term research project and the infrastructure in the marine biotechnology.

Recently, with the beginning of the commercial operation of high-speed railway, there have been a number of changes in track structure fields. Also, it is expected that the development and introduction of new technology will be increased afterwards. However, it accompanies a lot of risk to install new track structures of which performance and safety are not verified on permanent ways with high traffic density. Therefore, to minimize the risk and enhance the adoption of new technology, it is required to develop a systemic verification system for track structure. To do this, in this paper, main contents of a draft of guidelines for track structure verification, and main issues in debate such as criteria and method for verification, test conditions and test periods are discussed. Also, a process to choose a most appropriate one for a specific project out of proven track structures by the above verification system, the selection process by the technical investigation committee and the VE process to analyze the economical and maintenance aspects based on LCC concept in Korea Rail Network Authority is introduced.

Many nuclear power plants in Japan are approaching the end of their planned operational life spans. They must be decommissioned safely in the near future. Using augmented reality (AR), workers can intuitively understand information related to decommissioning work. Three-dimensional (work-site) reconstruction models of dismantling fields are useful for workers to observe the conditions of dismantling field situations without visiting the actual fields. This study, based on AR and work-site reconstruction models, developed and evaluated an information reference system. The evaluation consists of questionnaires and interview surveys administered to six nuclear power plant workers who used this system, along with a scenario. Results highlight the possibility of reducing time and mitigating mistakes in dismantling fields. Results also show the ease of referring to information in dismantling fields. Nevertheless, it is apparently difficult for workers to build reconstruction models of dismantling fields independently.

Animal and crop production systems were integrated on a single farm. This integrated farming system recycled nutrients on the farm. The separation of animal and crop production with the introduction of cheap commercial fertilizers, farms were not used land-applied manure. The on-line manure matching is one of the emerging business in the achievement of recycling and resource recovery. The manure matching actively promotes the reuse and recycling of by-products and manure. This study constructs to manure matching information system to solve the exchange problems between herders and croppers. Manure matching web sites designed. This paper introduces a web-based animal manure matching system. A manure matching service, part of the manure transport, links farmers who produce excess manure with farmers who can use the manure. Farmers registered with the service have requested manure. The manure matching service supports the transport project by linking farmers with excess manure with those farmers who can utilize the manure safely as a nutrient source. The goal of the service is to protect water quality by fostering efficient land application. Benefits to those who use the manure network include reduced disposal costs, lower purchase costs and recycling of manure. The manure matching is based on the principle that 'one persons waste is another person's fertilizer.' It provides a free online matchmaking service for environmentally safe manure recycling management system.
