New and renewable energy has attracted a significant attention since the Paris Agreement in 2015. Especially hydrogen energy is important for reducing greenhouse gas produced during transportation. The new government suggested that the eco-friendly vehicles, hydrogen infrastructure and the development of new and renewable energy are the major growth engines in the future. Hydrogen energy is also concerned as the main part of our economy in the national affairs. In the policy of Mission Innovation Strategy and the third Eco-Friendly Vehicle Master Plan, government presents the status, future direction, technical road map and distribution road map of hydrogen energy. With this trend, investments in the research and development on hydrogen and fuel cells have expanded and will continue to expand for the implementation of the policy. The cost reduction, technical innovation and the increase in the localization rate are required for the new and renewable energy, including hydrogen energy, to become the future growth engine.

Recently, the development of renewable energy sources in Korea has been needed due to climate change. One of powerful alternative energy resources to mitigate emission is to switch conventional fuels to renewable energy, such as bioenergy. In this study, current status of bioenergy conversion technology and its supply in Korea was investigate. Based on theoretical, technical and realizable potential of biomass in Korea, the amount of reduction of green house gases was estimated. The results shown that the contribution of biomass on 2020 reduction target of green house gases emission in power generation was $513,000\;tCO_2/yr$ and utilization ratio of technical potential of biomass was 6.4%. For the effective supply of bioenergy in Korea, more exact estimation of realizable potential of biomass in Korea and stable supply sources are needed.

In the maritime industry, the convergence of information and communication technology (ICT) occurs in two areas. The first one is the convergence of e-navigation technology to apply ICT to the maritime domain. This was led by EU's initiative and is also being promoted in our country. The other one is the convergence of autonomous ship technology to apply various ICT technologies for commercial purposes. This initiative is being led by maritime industries. In this paper, we describe trends of e-navigation and maritime autonomous surface ship technology convergence. Subsequently, we explain the standardization status of performance and technical standard bodies, international standardization organizations, and related standard-developing organizations to provide the interoperability of these technologies. Finally, we examine ongoing projects in Korea and suggest future directions for their R&D and standardization.

Recently one level higher intelligent switching board than established one by the application of intelligent building and digital system are being constructed. Therefore facility's high efficiency, high degree satisfaction, miniaturaization, standardization through application of communication technology and monitoring and controlling by computer system utilized by web-basis power control system and electric IT are practiced. Especially network must be constructed through unified IBS server that monitors every educational institute's switching boards in real time control system. And I intend to create methods to save energy and raise electricity quality by power demand prediction and remote-controled management and operation. In this thesis I intend to suggest measures of forming unified system through researching educational institute's ways of constructing switching board and status analysis and overcoming technical difficulties in user's side and saving and maintenance expense.

In this study, it was selected that in order to make an investigation into the status of the unit water content control of the ready-mixed concrete plants in the country, Capacitance Measurement Method out of various methods which are able to gauge the amount of unit water content in fresh concrete. Then, it were estimated that the quantity of unit water in fresh concrete and the technical standard of every mixture design of the six ready-mixed concrete plants chosen at random in the country. Finally, based on this study, it was proposed as fundamental data to utilize measurement techniques of the quantity of unit water for the quality control of the ready-mixed concrete in construction field.

Recent increases in the road and rail infrastructure, but the urban traffic problems such as accidents, congestion are increasing. The reason is that the high cost and lack of accessibility of railway transportation, the low quality of road services, and efficient transport links, etc.. The developments of a variety of policy and technical means are being performed to solve these problems. Among them, the Bimodal Tram which is combined low-cost of bus and high service quality of railway transportation is attracting attention. In this paper, the development status of technology and efficient utilization of operational and infrastructure elements for the operational efficiency, safety and passenger comfort of Bimodal Tram is studied.

This study develops a framework and instruments to diagnose the current knowledge management(KM) status of an organization and to suggest future KM implementation directions. Based on the comprehensive review of KM literature and KM case studies, we derive three main aspects(strategic, social and technical aspect) and seven critical factors(KM strategy, knowledge worker, organizational strucuture, organizational culture, KM processe, organizational knowledge, and information technology) for the successful KM implementation. The instruments developed in this study include every specific measurement items of each critical success factor, which are expected to help not only suggest a context-sensitive KM strategy but also evaluate current KM status of a designated organization. By introducing two dimensions of KM evaluation(effectiveness and necessity), a more holistic and contingent view of KM can be assured. Academic contributions as well as practical implications are discussed. Study limitations and future research directions are also provided.

A system of networked digital libraries will be a primary component of information infra-structure. The general strategy for digital libraries by the American university libraries is summarized as building of information infrastructure, content database construction, and project-based design. This paper describes the present feature and status of digital libray programs being implemented by the libraries of Michigan University, Carnegie Mellon University and Virginia PolyTech & State University.

In this paper, we are looking for requirements of software, hardware and application for use in network-based robots and also directions in building standardization and research activities by reviewing technical status of the robot industries developing robots. The questions are including awareness of RUPI(Robot Unifies Platform Initiative) activities, target market and applications, hardware specifications, software development technologies, and HRI(Human Robot Interaction). The RUPI committee creates standard and drives implementation software for network-based robots through industrial requirements as like of the results. Many robots have been developed and launched services based on RUPI 1.0 standards. Based on this achievement we are expanding RUPI standard to include thin and thick client robots. The results also show that which one is important and urgent technology in the sense of industrial robotic business.
