Digital-ship is the next-generation ship with an one-man bridge system which consists of INS(Intelligent Navigation System), AIS(Automatic Identification System), and IMIT(Integrated Maritime Information Technology). INS implements the functions is related of the ship's navigation, and supports in the digital GIS environments optimal route planning, stranding and a collision avoidance among the ship, an economic navigation, and an integrated control of ship's engine. AIS prevents the ship's collision by means of transmitting periodically the own ship's information to the other ship or the shore control center. IMIT systems supports the integrated fiat-form in ships, the communication between a ship and a control center of the land using the INMARSAT, OrbComm, Ocean Observation Satellite, and etc. The satellite communication in ships can monitor the ship at an earth control renter. This paper deals with the method for system implementation of digital-ship and the detailed sub-system.

As container traffic is increasing, the introduction of mega-vessel has had a significant impact on the ports and terminals business. This movement of container shipping has led to intensely competitive environment among ports, so substantial pressures to develop new container ports or to expand existing ones, have been grown. However, it requires a huge investment, especially cost and time, to overcome environmental, geographical and financial restrictions generated from developing a port. This study addressed the Mobile Harbor, the new concept of marine logistics system as an alternative strategy. We performed an economic analysis on the introduction of the Mobile Harbor in coastal transport sector and also a sensitivity analysis to examine the effects of changing factors related on the economic evaluation. We have examined the value and application of Mobile Harbor as a preliminary study, which may contribute to further studies on the Mobile Harbor.

Based on the development of IT(information technology), the explosive diffusion and growth of the new media and services in Korea has attracted keen international attention. The construction of IT infrastructure driven by the proactive social informatization policy of the government has also been spectacular. Korea has persistently pursued strong 'new media-informatization policy' with three main objectives in mind: 1)Industrial-economic value creation; 2)socio-cultural value creation; and 3)building of the knowledge society-knowledge state. But its consequence is rather paradoxical. While its performance is excellent in terms of quantity growth of industry and technology, quality development of society, culture and knowledge creation is lagging far behind. This paradoxical outcome originates, not from any simple policy error, but from a structural problem inherent in new media-informatization policy in Korea which has long been captured by developmentalism. In order for Korea to harvest the reward of strong new media-informatization infrastructure, it needs to institute a policy structure based on a knowledge IT strategy such as research and development of core and patent technologies, design and production of quality contents, networking knowledge bases of society, etc.

This study is how to effectively apply this SNS based education to multicultural families and is to analyze how any change in the lives of multicultural families. Multicultural education in Korea has been steadily run by the government and local authorities, however the lack of free time, distances, for economic reasons and unfamiliarity of the new culture and language, immigrant women are not getting the education. To solve this problem, we provide the necessary information, such as culture, education, laws of the Korea for multicultural families and analyze their effect on life adjustment. And we also analyze changes to relieve loneliness. As a result multicultural family education utilizing SNS is verified that there is effectiveness to adapt and understand Korea. As well as inter-family, multicultural members to seamlessly communicate between each other that proved helpful to relieve loneliness.

The public-private partnership concept can encompass a broad range of cooperative relations and a broad variety of programmes in terns of size, objectives and design. This paper aims to analyze the components of public-private partnership mechanisms in the context of science and technology innovation policy. The research methodologies are based on semi-structured interviews with policy makers in four countries with six PPP programme : the France, the Netherlands, the Australia and Austria. It also attempts to understanding of the components that explain the increase of collaboration between national innovation system and PPPs. The taxonomy and essential components of PPPs were identified : mission-oriented PP/Ps, market-Oriented PP/Ps, cluster-oriented PP/Ps, and ISRs-Oriented PP/Ps. The taxonomy of regulatory regime can be a reference point for identifying the relative status of Korea's PPPs.

Korea has established an advanced infrastructure for real-time precise positioning such as CORS, virtual reference station service and perform continuous upgrading. However, in order to utilize the national infrastructure, it is necessary to process the acquired spatial information and take many steps to derive the final product. In addition, this process is highly dependent on foreign software. In this study, GNSS field survey system was developed and evaluation of its usability was performed. Real-time GNSS field survey system was developed and the system improves user̓s convenience and usability. The system was able to conduct survey effectively and produce the results. In addition, we compare the existing software with the survey performance to show the availability of the real-time GNSS surveying system. The system developed through the research can perform all the functions from real-time survey to the production of the outputs. It can create economical added value of the foreign software as a whole and simplify the work required for post-survey performance.

Different to other social infrastructures, bridge elements or bridges can be damaged or collapsed and this may cause death toll and severe social and economical damage, bridges should be managed to maintain a safety level. Diverse strengthening methods is developed to improve a deteriorated bridge performance up to original design level. But rational decision-making process and methodologies to select a optimum strengthening method are absence yet in Korea. This paper therefore derived items and proposed methodologies for quantity estimate considering uncertainty to select a optimum strengthening method among conceptually designed alternatives. And also, to demonstrate the applicability and verification of the proposed approach, it was applied to select the optimum strengthening method for the deteriorated T-shape concrete girder bridge. The model and the procedure can greatly contribute to the uncertainty-oriented alternative selection.

A research of grid computing that is the combination of computer resources from multiple distributed administrative domains to get large amount of computing power is underway. This research is an application of grid technology on a urban facilities management system based on u-GIS. The sensors are set up in the urban facilities to make it monitoring. If an amount of sensors and gateways is increased, the server needs more computing resources to process the data. In this study we developed the skills that can distribute jobs to idle gateway, in case of the server capacity had approached threshold. It will be possible to develop of economic and efficient system that will apply to large amount of data processing about u-City.
