  • In this research, we investigate the method to support decision making of researcher when they estimate the safety on the subway using AHP of Saaty. To apply this technique, we apply to subway system. The AHP suggested by Saaty in 1971 is a tool to support a decision-making including the personal opinion and intuition, and it is easier than other method. Then, it has an advantage that control the complex object having multiple criteria simply. And we suggest the eight stage of accident type and the five criteria that must meet. Based on AHP, we concluded a safety in subway is more important factor than any other factors including economic points of view.

  • The primary objective of this paper is to investigate the corridor of Eurasia High-Speed Railway Network from the governmental view of the Republic of Korea, whose High-Speed Train has been recently operated. The country is also expected to figure out the changes of Eurasia infrastructure system under the assumption that Trans-Korean Railway is connected to the Continent. As a result of research, the corridor connecting the TKR to TSR seems to be more attractive to the Republic of Korea than that of the TKR-TCR under the current economic and operational environments. However, even in a case, the railway linkage through the TSR between Europe and Asia should remain a supplementary means of the sea transportation route. Lastly, TSR may need a program of structural reforms, in order to continuously provide preferable services like the Pan-European Transport Network (PETN) which is currently initiated by the European Union, such as to improve outdated infrastructure (railway, bridges, signal systems, etc.), to simplify and to standardize the process of custom clearance and internal tariffs, and ultimately to construct a uniform management system for the corridor linking the TKR to TSR.

  • The majority of small/medium sized shipbuilders in Korea is poor in capital and then, should be restructured as an efficient production system with low investment. Due to considering this situation, the cooperative work system is proposed, in this study, as more effective production system for small/medium sized shipbuilder The cooperative work system Is the production system that many small/medium sized shipbuilders in a group jointly share the common facilities except minimum equipments and have managerial cooperation such as joint purchase of raw materials. The efficiency of cooperative work system is proved from economic and technical point of view with the case study of FRP shipbuilders of Sapjin industrial complex located at Mokpo area.

  • Review of the global change in various energy usages and resulting environmental impacts were made in terms of population increase, economic development and energy consumption. Greater use of fossil fuels in past couple of centuries give rise to acid rain and gradual climate changes mainly due to Green House inducing gases emissions from fossil fuel combustion. In view of the forthcoming Kyoto conference in December, various alternative options were assessed. To cope with rapidly developing robust Korean economy, the alternative energy options for the sustainable development in 21st Century would be the wider use of Nuclear Energy in parallel with constrained use of fossil fuel and renewable energy development. However there are many hurdles to overcome. One of the most important element is to improve public acceptability of those alternatives. Since public acceptance depend heavily upon individual perception on specific energy technology applications, the basic energy technologies education from primary up to high school education and the related curriculum organization is important. The suggested improvement in education for Nuclear Energy Application was made on the basis of advanced industrial countries with substantial Nuclear Energy Application programs.

  • A country's macro developing strategies will greatly impose upon its water resources allocation. Based upon the relationship between national macro developing strategies and water diversion projects layout, the paper discusses the vital influence of water diversion projects caused by China's food security and sustainable development strategy implemented in recent years, and points out that it is an inevitable choice of constructing inter-basin water diversion projects in north China in view of local water resources can't meet the demand of socio-economic development and eco-environment protection, and then recommends China's water diversion projects layout in the current and future, which attaching most importance to the South-to-North Water Diversion Project.

  • This study is to summarize the contents for the investigation and design of the construction for oil storage. Since underground caverns are large scale, in their construction one should consider the mechanical stability of caverns and the economic view of construction. On the basis of them, cavern's section and layout were determined and water curtains were designed to maintain hydraulic equilibrium so that gases were sealed tightly. Also the supporting criterial for rock bolt and stotcrete were determined by means of the classification of rock masses and the results of finite element method. The criteria of grouting reinforcement were presented according to the results of injection test in the pilot holes of working face.

  • Analytic solutions of heat conduction during welding which were first found by Resenthal have some restrictions. One of these is that models to which analytic solutions can be applied must have simple geometric shape, and another is that quasi-stationary state must be created. On the other hand, computational methods developed recently with the aid of the computer can overcome these shortcomings, but the methods raise problems from economic point of view when they are applied to 3 dimensional problems. Taking account of these problems, a new method combinig the analytic method with the computational one is proposed. This method can be ued in weldments with complicated geometric shape in non-stationary state, but with the aid of the analytic method can reduce the computing time.

  • The purpose of this qualitative case study was to investigate the causes and processes of marital conflicts among intermarried families in Korea. The participants were 19 Korean men and their 19 Filipino spouses, who had experienced domestic violence. Their marital conflicts seemed to result from their lack of information about each other due to the short-term courtship, from the marital inequality based on the wives' lower economic status, and from the mother-in-law's interference in their marital relationships. Korean men showed ambivalent feelings about their wives' adaptation to Korean society. They wanted their wives to team Korean culture but worried that their young and educated wife might leave them, which could be called as "the fairy and woodman syndrome." The exploratory view of the study highlights the important psychosocial and cultural aspects of marital conflicts, and suggests the supporting systems for the intermarried families in Korea.

  • ICT 관련 규제들을 살펴보면 현실에 맞지 않거나 실행하기 어려운 규제들이 많다. 정부에서는 '경제혁신 3개년 계획'을 발표하여 ICT기술의 발전을 도모하였지만, 기업들은 정책으로 인해 발전하지 못한다고 생각하였으며, 세계 최고 수준에 도달해있는 기술이 있지만 규제로 인해 국제지표에서는 그다지 높은 성과를 내지 못하고 있다. 국내의 규제를 바라보는 몇가지 시선을 본문에서 다루고 문제점들의 해결방안을 모색하였다.

  • A real-time monitoring system for in-situ soil remediation technologies is developed and then applied to electrokinetic remediation technique in the field trial tests during 150days. The developed system is consisted the controlled program based on internet web page, data logger, measurement instruments and so on. In the measured items there are pH, temperature, electrical current and potential, vacuum pressure. The results indicated that the system is successively applied to electrokinetic remediation technique, and further research considering economic view and multi purpose system for in-situ soil remediation technologies is needed.
