The Chinese government portrays the One Belt One Road Initiative (BRI) and South Korea President Park Geun-hae's Eurasia Initiative as a win-win opportunity which will hurt nobody's interests, but some South Korean commentators have interpreted it as much more than just a trade and development deal: they focus on the geopolitical implications and the possibility that the balance of power in Asia will be disturbed. South Korea depends upon its maritime-oriented Sea Lanes of Communication (SLOC) in focusing on its alliance with the US to deter North Korean threats and explore its export-based economic growth and development, and yet cannot afford to be left out of these initiatives which could transform the economic and logistical linkage between South Korea and Europe. Given its negative reception by the some pundits, however, South Korea should be more precautious for expressing only full-fledged supports for the BRI and Eurasia Initiative. Opponents of these two initiatives doubt that its putative benefits can be realized, at least in the short term, arguing that creating the necessary rail interconnections may be too costly.

China and Korea are good neighbors and partners. Since the establishment of diplomatic relations in 1992, the two countries have made promising achievements in political, economic, and humanistic exchanges for over three decades. In particular, bilateral economic and trade relations have yielded fruitful results, attracting worldwide attention. There are also unavoidable issues in the rapid development of bilateral trade and economic cooperation. And it is of great significance to look back on the past and look forward to the future on the 30th anniversary of the establishment of diplomatic ties between China and the Korea. With the upgrading of China's industrial structure and technological level, the bilateral trade relationship has gradually shifted from a complementary one to a competitive one. It is essential that both countries keep in mind the mutually beneficial nature of their relationship and make due contribution to the development of the Northeast Asian region and the world economy.

The recent explosive use of the Internet and the development of computer communication technologies reveal serious computer security problem. Inspite of many studies on secure access to the system, generally, the attackers do not use the previous intrusion techniques or network flaw, rather they tend to use the vulnerabilities residing inside the program, which are the running programs on the system or the processes for the service. Therefore, the security managers must focus on updating the programs with lots of time and efforts. Developers also need to patch continuously to update the Program, which is a lot of burden for them. In order to solve the problem, we need to understand the vulnerabilities in the program, which has been studied for some time. And also we need to analyze the functions that contains some vulnerabilities inside. In this paper, we first analyzed the vulnerabilities of the standard C library, and Win32 API functions used in various programs. And then we described the design and implementation of the automated scanning tool for writing secure source code based on the analysis.

Recently, many car drivers were damaged by gas station which support similar oil product and not quantitative gas. It were expected to increase above-mentioned damages. By using similar oil products, caused damage are working of lubrication in the fuel line, elf-cleaning function, the part of the early deterioration, impure accumulation in the fuel line, toxicity material in exhaust emissions and unidentified chemical reaction. To prevent these damages, proposed system use in-vehicle state data with OBD-II protocol, measure quantitative gas and similar oil. In this paper, there have implemented similar oil identification and quantitative gas system through OBD-II scanner to provide WiFi communcation by using WinCe development Board.

Data networks at sea will be overlapped networks with not only traditional carriers such as RF, satellites but also BWA like wireless LAN, WiBro, and WCDMA in near future. In this paper, an overlapped MANET model for data networks at sea, and a routing protocol (OMH-MW) selecting optimal transmission medium for each hop in routes are proposed. OMH-MW measures the optimality of each medium regarding the transmission characteristics of each application and those of the medium in together. The most suitable medium to each link is selected as the link in routes. Performances are compared with those of the MWR (Max-Win based Routing protocol searching optimal routes with only one medium).

This paper introduces the design concepts and characteristics of WinDS3000$^{TM}$ which is a trade mark of Doosan's 3MW offshore/onshore wind turbine. WinDS3000$^{TM}$ has been designed in consideration of high RAMS (Reliability, Availability, Maintainability and Serviceability) and cost effectiveness for the TC Ia condition in GL guideline. An integrated drive train design with an innovative three-stage gearbox has been introduced to minimize nacelle weight of the wind turbine and to enhance a high reliability for transmission. A permanent magnet generator with full converter system has been introduced to get higher efficiency in part load operation, and grid friendliness use of 50 Hz and 60 Hz grid. A pitch regulated variable speed power control with individual pitch system has been introduced to regulate rotor torque while generator reaction torque can be adjusted almost instantaneously by the associated power electronics. An individual pitch control system has been introduced to reduce fatigue loads of blade and system. The wind turbine has been also equipped with condition monitoring and diagnostic systems in order to meet maintainability requirements. And internal maintenance crane in nacelle has been developed. As a result, the maintenance cost was dramatically reduced and maintenance convenience also enhanced in offshore condition.
