A key objective is to meet the requirements for safe marine transport and protection of the marine environment by providing a comprehensive mix of Aids to Navigation commensurate with the amount of traffic and the degree of risk. The development of e-Navigation is driven by the compelling need to equip the master of a vessel and those ashore responsible for the safety of shipping with modem, proven tools to improve the reliability of marine navigation and communications. Although position fixing using GNSS is widely used, radar and visual AtoNs continue to be needed to provide safe, secure and environmentally clean navigation. The paper considers the role, evolution and future provision of traditional aids to navigation in an e-Navigation environment from both a technical and mariner perspective.

Since 1960s. container shipping volume has increased dramatically and continuous on a trend of rapid growth, and so the number of containers handled at the port increases. In order to improve yard crane operating efficiency, the precise position measurement of the yard crane is important. This paper describes the method to measure the absolute position of yard crane using the output pulse of an encoder and infrared sensors. The crane position is calculated by counting the output pulse of an incremental encoder, which is mounted on the wheel in the crane. By the way, the wheel slippage on rail may cause some errors in crane position information obtained from encoder pulses, and the errors in the crane position information are compensated with infrared sensors. The performance of proposed method is verified on experimental results with the simulator of yard crane, the size of which is about 1/10 with the real crane.

According to the report prepared by Legl Committee of IMO, 1978, since the disaster of motor tanker Amoco Cadiz carrying approximate 220, 000 tons of crude oil was wrecked on the coast of France and damaged the largest oil pollution accident in shipping history, Legal Committee of IMO has studied and discussed a new Salvage Convention with assistance of CMI. CMI has prepared a new draft convention under the chairmanship of professor Erling Chr. Selvig and adopted it as a report of CMI to IMO in the 32 Internaltional Conference of CMI, Montreal, May, 1981. This paper has been written to study comparatively andinterprete the questions and/or considerations of the new draft convention by the delegates participated in the Legal Committee of IMO in particular on the private legal view of it. This Salvage Convention Draft has not yet been deliberated thoroughly to agreed the revisiion of the 1910 Convention in accordance with CMI Report 1981 until session 54, March 1985. Therefore this paper has been prepared in the light of the comments made at the Legal Committee in order to interpret the legal questions and contents of the new draft.

Domestic distribution warehouse has been developed as a strategic strategic point for inventory management and shipping of goods for companies. Warehouse is classified as distribution center, transport center, complex center depending on the role. Currently, at the same time it is considering the price factor such as rent price or land price and and logistical capabilities when considering the location of domestic warehouses. The price evaluation factors has specific methods for the evaluation but logistical elements is not currently clear. In this study, we have studied location selection of distribution center considering the logistical elements through expert surveys.

크루즈 페리 선박의 인테리어 섬유 내장부품은 고도의 난연성과 내구성, 그리고 높은 수준의 감성과 심미적 기능을 만족하는 고기능성 소재로 구성된 섬유 복합체이다. 이는 화재, 전복 등 돌발 사고에 대하여 탑승자를 보호하고, 쾌적한 실내 분위기를 제공함으로서 안전운행을 유도하며, 높은 수준의 감성과 심미적 기능을 부여함으로서 품위와 가치를 증가시키는 기능이 있다. 난연기능이 부가된 난연사의 경우 복합가공 즉, 방오, 항균, 소취 기능을 추가 부여하게 되면 난연 기능이 급격히 저하되는 결정적인 단점이 있다. 이로 인해 가혹한 난연 성능이 요구되는 선박용 인테리어 섬유제품의 경우 그 규격을 만족하기란 쉽지 않기 때문에 원사제조에서부터 염색공정, 가공공정에 걸쳐 각 단위 공정별로 복합적으로 난연, 방오, 항균소취 기능들의 추가 보완이 필요한 실정이다. 또한 최근 사용자 입장에서는 용도에 따라 여러 가지 기능이 복합된 원단을 요구하는 사례가 많아지고 있는 실정이며, 많은 후가공 공정시 난연가공과 더불어 복합적으로 추가 가공시 난연성 저하 등의 문제가 있다. 본 연구에서는 선박용 인테리어 섬유제품의 Spec.을 만족시키기 위해 난연 직물의 염색 후가공에 적용되는 염조제 성능을 조사하고 고견뢰 및 균염을 만족하는 난연 내광 등의 복합기능성을 확보하기 위한 기초기술을 검토하였다.

The Ministry of Maritime Affairs ＆ Fisheries have plaining the advancing fishery information integrated system for the fishing present condition, marine resource administration and applicability considering. The fishery information communication system is build up to the raw data ＆ process-network-content. The communication system must be small size, low cost and adapted SSB transceiver, that is using fishery shipping. In this paper We present digital data communication network to exchange information for fishery and safety between fishing ship and coast station in cheeper communication fee using SSB in HF band.

In these days, 8,000TEU container ship service launches in shipping service at latest based on the economy of scale, unit cost related with ship operation on ocean decreases in proportion to increase of ship scale and mega ship over 10,000TEU is on planning. Most of the exiting researches have performed from the perspective of total operation cost from mega port to mega port. However, the purpose of this paper is to estimate economic efficiency by ports selected Hub port from total cost point of view, operation cost, port charge, feeder cost, etc.

At the present, e-commerce takes the place of existing transaction form in structure in the world trade by advancement of Information Technology and diffusion of Internet. There is no exceptions of this tendency even in industry of maritime and logistics. So, global shipping lines and logistics companies try to construct the e-Business network system for increasing their competitiveness in an are of cyber. However, in Korea, most of companies prefer "final handshake" as the traditional way of transaction to "e-commerce", because they bear a distrust in mind about the outflow of transaction information and security of settlement. So, number of companies using e-commerce is very small, and this situation causes the limited factor for activating the transaction structure of it. The rate of using e-commerce in logistics industry is lower than other industries, even more higher effectiveness is expected when they use it. Especially, it is very necessary not only e-commerce but also e-Logistics which can serve information of freight cost on cargo flow, operation cost and schedule, and tracing information of cargo. Increasing the necessity of e-Logistics, this study research the rate rf using e-Logistics focused on maritime and logistics companies, and analyze the transaction form among members of these industries for improving them. In detail, this paper examine the drivers for activating e-Logistics, and present the effective factors for a successful development of these industries.

As the number of ships and goods shipped by marine transportation increases, almost all shipping companies adopted foreign crews in order to overcome lack of seafarers and be competitive for manning cost. Thus, these days it is inevitable to work with foreign crews aboard ships, but there occur many marine accidents due to language barriers and communication problems under multicultural and multilingual shipboard environments. In order to resolve troubles resulting from different languages, reduce miscommunication risks, and make working on ships safe and efficient, this study recognized the current status of ships with mixed crews, analyzed marine accidents caused by communication problems not only in Korea but also in other countries using analytical methodologies. Additionally, existing hazards affecting miscommunication were identified and risk of miscommunication was quantitatively evaluated while offering suggestions and future forecasts. Consequently, in this study we suggested that fundamental dialogues are to be necessarily educated on the ships with foreign crews so as to reduce the language barrier and risk of miscommunication. Furthermore, a standard maritime Korean language program and manual targeting Korean coastal vessels would be developed in the next step.
