This study examines the issues regarding the selection competition process of offshore wind power operators conducted in Japan in 2020. It also explores the implications of the findings on the legal system of Korea for the introduction of offshore wind power in the future. Drawing on Japan's example, Korea must reconsider the importance of the price aspect when introducing offshore wind power and adopt policies that prioritize balanced industrial development and focus on regional and domestic economic ripple effects.

Opening 21th Century, all the Countries of the world has been focusing on build up the foundation of cultural infrastructure in a various way, since the awareness of importance for cultural design products has been turnover. For this reason, all the countries in the world, recognize that it is more important than any other things to plan to establish a structure which is suitable to the real conditions of a region in order to efficiently manage or operate their cultural environment, in particular, they think it is urgent they should contrive to develop their regional industries with new information media, introduction and spread of the up-to-date technique of design. However, our regional related industries very difficulty for the moment for them to apply new, designing technique or to settle technical bottlenecks themselves. Accordingly, in order to resolve such a structural point at issue, this study has carried the newly designed and developed, wooden, cultural craft items that were produced by utilizing the ultramodern digital technology installed at TIDIC, it would contribute to achieve some global cultural products.

Electrical or electronic products have been becoming smaller and high integrated recently, with printed circuit boards(PCB's) being the key components for these products. The introduction of new technology of surface mounted devices(SMD) opens new ways towards high integration on the PCB. Many plants in eletronical industry which produce high variety of PCB's to meet the demands of customer orders require flexibility in PCB's production lines. This survey paper describes the related optimization problems and solution methods to the automated surface mount technology(SMT) assembly lines, and provides with the research direction for improving flexibility.

In order to manufacture high quality goods, the engineers who will design them has to have board technical experience as well as profound engineering knowledge. The engineers also be able to design and manufacture well development goods base on new advanced technology. Design process can be defined as transforming activity raw material into finished producted for human needs. The wealth of nation depend on its ability to retrieve natural resources and manufacture goods. Its ability, creation of goods, is most fundamental component of economic wealth of rich country. The rich countries have combine their own design knowledge with computer technology and create new effective design process. In this paper, one of the useful and practice design process created for railway industry is introduced. Base on the concept of this design process, the automatic wheelchair lifter design for railway vehicle is performed.

The government introduced a mandatory installation system of new & renewable energy for public building to meet the target of greenhouse gas reduction and also suggest a correction factor for new renewable energy to expand the installation of various new & renewable energy systems. The introduction of correction factors, however, was followed by the reduction of installation size of new & renewable energy sources. Assuming that it was caused by a correction factor for each new renewable energy source calculated by the initial costs, this study proposed a new correction factor approach based on payback periods to reflect the technology element in the calculation process of correction factors additionally. The application results of new correction factors show that it was possible to do complex calculations including the economic and technological aspects to select a new & renewable energy system and that the installation size was also enlarged.

After general introduction for hyperbranched polymers, hyperbranched polysiloxysilanes (HBPS) were introduced as new functional polymers. Vinyl terminated HBPS was synthesized starting from AB2 type monomer by hydrosilylation reaction. Vinyl group can be converted various functional groups such as carboxylic acid and alcohol. HBPS had strong interaction to inorganic surface. As an example of this phenomenon, silica gel bead for HPLC was modified with thermo sensitive polymers. The resulting bead was successfully applied to Green Chronatography.

Laser cleaning has begun to attract a considerable amount of interest recently as a new cleaning technique among scientists and engineers. The unique characteristics of laser cleaning are currently finding successful applications in industry, in medicine as well as in the world of art conservation. This paper takes an overview of the laser cleaning technique itself including basic principles and characteristics, and provides an account of current trends especially with regard to practical applications. Experience with its successful applications in various fields shows that laser cleaning may be about to emerge as a real alternative to conventional cleaning methods.

Recently, due to the development of new technology and products, FA has been accelerating for obtaining high-quality and saving of resources and power. Introduction of automation to the field which has bad working condition is needed and welding is one of these field. In this study, solving algorithm for down hand control which requires in the automatic are welding system is proposed. For the verification of the algorithm, numerical examples are shown and visualization is carried out using developed graphic tools.

Growing qualitative and cost-based competition with the roads and air modes will be oblige the railways to make better use of their existing infrastructure than present. Development and use of new signalling and safety systems and introduction of wide-area control systems may make it possible to operate railway efficiently. Therefore. a comprehensive series of measures must be developed in the fields of technology, planning and management, measures which can operate today's korean railway systems intelligently and achieve cost savings, better quality services and improved results.

This paper is the introduction of our work on distributed load scheduling in single-level tree network. In this paper, we derive a new calculation model in single-level tree network and show a closed-form formulation of the time for computation system. There are so many examples of the application of this technology such as distributed database, biology computation on genus, grid computing, numerical computing, video and audio signal processing, etc.
