By Chinese growth, economic development and investment of the West-coast are consisting. Specially, the West-coast area need tourist development and tourism Import for the Incheon and the Pyeongtaekhang of the Gyeonggido Province, China trade through the Chungcheongdo Province area. According to such regional special quality, the railroad tourism industry should be activated. Sunset of tourism infra in the West-coast is high value as representative goods of the West coast. Development of the theme railroad tourism industry that utilize the tide may maximize regional advantage of China and capital region. This research is basis investigation to examine development possibility as sunset theme railroad tourism industry of the West-coast. Scope of this research limited by the sunset theme railroad tourism industry for the Chungchongdo Province area.

High-accuracy micropatterns such as V-shaped microgrooves are increasingly in demand for various engineering areas. And the technical trend goes for large surface areas in precision machining technology. So micropatterns with large surface areas are expected to play an increasingly important role in today's manufacturing technology In this study, we focused on developing machining technologies. First, a machine vision system for precise tool setting is developed. Second, an on-machine measurement (OMM) system for large-area measurement is implemented. And also software for tool path generation and simulation is developed. With these technologies we fabricated large-surface micropatterns in an electroless nickel-plated workpiece with single-crystal diamond tools and a 32-in, $675mm{\times}450mm$ mold with tens of V-and pyramid-shaped micropatterns.

The purpose of this study is to understand the high saline water phenomenon of Handong-ri area in the eastern coast of Jeju Island, were investigate the tidal effect of groundwater level, variation of electric conductivity and temperature, geological logging on the monitoring wells, chemical water quality, and ratios of oxygen istope of groundwater and seawater Results in investigating variation of interface zone of freshwater and saline water represented that the hyaloclastites formed at below groundwater table is developing toward the coast; this area consisted of stratum of good permeability. Hyaloclastites is presumed the main path of the high salinity water There are a lot of movement by the tide at upper layer. Salinity of lower layer spreads to upper up step in proportion to tidal energy. Because of hydrogeological characteristics, Interface zone of freshwater and saline water is made, High salinity of groundwater occur in east coastal area of Jeju Island. Therefore, I think that high saline groundwater phenomenon is natural condition by simple mixing.

China has been aware of the urgent need of developing electronic and information industry in order to improve its productivity. Since 1991, IT industry has been one of the main factors to influence China's economic growth. In the results of the efforts to develop its IT industry, China has achieved average 25% yearly growth rate of IT manufacturing industry since 1991. We will take a look at haw the main IT products' performances was, how the role of IT industry was in China economy and in China's trade and how the prospect of China IT industry will be. However, we need to know that, depending an the different areas, the environment of the China's IT industry will be quite different. In China, the east coastal area has the better environment of technology, menpower, infrastructure, and fund for the development of IT industry and the IT industry of this area is very competitive, comparing with the middle and west area.

Recently, rising of the convergence of technologies such as IT, GIS, GPS, and Sensors is developing the new information environment which enables man-to-man, man-to-object and object-to-object to exchange information anywhere and anytime. The Korean government has made great efforts to implement the virtual government with development of the next generation technologies continually and dynamically. These efforts for implementing e-government can be summarized by the citizen centered, integrated services, the customized personalization, the intellectual services, and the integration and cooperation between each offices for providing those services. Therefore, we wish to present the model of wide-area intelligent information systems which can provide services to form the future of this virtual government with GIS infrastructure in this study.

This study was carried out to survey the degree of the perception and necessity of wedding food prepared by housewives. The participants of the survey were 331 housewives lived in Busan and Kyungnam area. The findings could be summarized as follows: The housewives lived in Busan and Kyungnam area had evaluated the necessity of wedding foods, Paebaek foods or Yedan foods. The respondents of 36.6% answered that they will order wedding foods from specialists, whereas 28.7% said that they will prepare them by themselves. More than half of the respondents(56.2%) thought that current wedding foods were prodigal and have to be done in thrifty manner. Broadly 46.8% of the respondents considered that the ritual practices of wedding foods will decrease steadily. A conclusion was that lots of participants had a negative view of wedding foods and pointed out the necessity of developing them to reflect traditional wedding customs with economic costs.

The Emergency Exit System is evacuation equipment that operated by crew or passenger when emergency state such as fire, accident, etc in the rolling stock. Generally front emergency exit is installed in the drivers area and it is isolated to passenger area, so its design is little big easy. But front emergency exit that is installed in driverless vehicle have to consider not only anti-vandalism and failure but also its design because it is installed in the passenger area. Therefore, we survey the characteristic, function and needed condition the emergency front exit of driverless vehicle and present the developing system that can be a help to make design.

In reverse engineering area, it is rapidly developing reconstruction of surfaces from scanning or digitizing data, but geometric models of existing objects unavailable many industries. This paper describes new methodology of reverse engineering area, good strategies and important algorithms in reverse engineering area. Furthermore, proposing reconstruction of surface technique is presented. A method find base geometry and blending surface between them. Each based geometry is divided by triangular patch which are compared their normal vector for face grouping. Each group is categorized analytical surface such as a part of the cylinder, the sphere, the cone, and the plane that mean each based geometry surface. And then, each based geometry surface is implemented infinitive surface. Infinitive average surface's intersections are trimmed boundary representation model reconstruction. This method has several benefits such as the time efficiency and automatic functional modeling system in reverse engineering. Especially, it can be applied 3D scanner and 3D copier.
