Racetrack coils are used in many areas of superconductivity applications such as generators, motors, maglev, wiggler magnets and so on. Especially now a days a few advanced nations including U.S., Japan are developing high temperature superconducting(HTS) wire which has better performance than low temperature superconducting(LTS) wire. Most of HTS wires such as BSCCO-2223 are manufactured with PIT(Power In Tube) process, so the shape of the wire looks like tape different from LTS wire with round cross-sectional appearance like normal conductors. Generally HTS racetrack coils are composed of a few partial double-pancake colis and then the double-pancakes are jointed each other according to their applications.

EU is in the process of developing a new european global navigation satellite system - Galileo project - which technologies and capitals from member states of EU are put into, after determining to set up a separate GPS against that of US late in the 1990s. Galileo system is commercial global navigation satellite system, which allows other else nations outside of EU to participate in system development and operation, different from GPS. Korea also decided to join in the project on February in 2005. Galileo system provide 5 Services - Open Service, Safety of Life, Commercial Service, Public Regulated Service, Search and Rescue Service, and especially it can be applicable to safety-critical areas, and is to provide its part of services certified. In this paper, we are to compare the services of Galileo system, and to present necessary factors to be considered, and the applicability to use the Galileo system in safety-critical application areas, such as train control system

Many advanced nations have been developing the next generation logistic systems to effectively deal with gradually increased logistic flows over the world. Particularly, dual mode trailer(DMT) systems are significantly focused as a new alternative transportation which basically provides integrating of the land and railroad services. This paper presents new driving mechanism for DMT systems using the hydraulic pressure cylinder systems. Such is mechanically composed of supporting and rotating parts independently, which are mostly important for whole system performance. We analyze feasible operational problem occurred in driving mechanism from the conventional DMT systems and compare our proposed deign specification with the Modalohr DMT system to demonstrate its reliability and practicability.

I have already reported about the necessity of international cooperation, our role and measures under the present conditions of private technological exchange in the Japanese and Korean Consulting Engineers Meeting at Taejeon, Korea. Continuously I have been discussing whether we, Japanese ＆ Korean consulting engineers can give technological cooperation and support with the regard to industrial technological development, enhancement of industrial infrastructure, social and economic development. I am focusing on Vietnam which has been in the course of economic development to excess in a sense and this country attracts the world's attention. I probe the possibility of technological cooperation under the cooperation of Japanese & Korean consulting engineers while I introduce the present conditions of Vietnam. In addition Vietnam has become a member of ASEAN officially, and the foreign investment in Vietnam has gotten on the right track. Moreover, the regularization of lawsystem in Vietnam is well under way and they aim at joining advanced nations in the 21st century.

Ever since the United Nations Framework Convention on Climate Change(UNFCCC) was agreed to stabilized greenhouse gas(GHG) concentration in the atmosphere at 1992, most countries including Korea have been developing strategic plans and implementing a number of R＆D programs to develop the measures to reduce the emission of GHG. Therefore, it is necessary to investigate the plans and programs for our country to develop more competitive technologies and to be more active and attentive in international meetings. In this paper, the energy policies of advanced countries will be analysed and be compared each other along with the Korean policy. Furthermore, the carbon dioxide reduction and sequestration R＆D programs in the countries will also be studied.

As the United Nations announced Sustainable Development Goals (SDGs) in 2015, the world changed its development goals from focusing on efficiency to equity. As a result, in the health sector, universal health coverage (UHC) has become one of the main issues. This paper reviews and discusses on future direction and issue of official development assistance program for developing countries. Korea International Cooperation Agency under the Ministry of Foreign Affairs published on Korea International Cooperation Agency's mid-term health strategy 2016-2020 developed on participation program with stakeholder including governments, civil society partner organizations, and educational institutions. The SDGs expands non-communicable diseases, UHC, and global health security from the existing Millenium Development Goals health sector. Progress toward UHC underpins the achievement of all other targets under SDG Goal 3. Progress in reducing health inequality across the life course is drawing on overall data and from specific target. In order to achieve SDG 3, a multi-disciplinary approach, convergence between IT and u-health of this development, is desirable.

Background: Occupational injuries cause major health problems, which the developed, developing, and underdeveloped nations worldwide are facing today. The present study aimed to assess dental caries, periodontal health of stone mine workers, and the relationship between wasting diseases and the years of working experience. Methods: The study population comprised 510 men, selected based on the stratified cluster sampling procedure. Clinical oral examinations were carried out, and periodontal disease, dental caries, and wasting diseases were recorded. Results: Workers were in the age group of 17-56 years; the prevalence of dental caries in the workers was found to be 74%, with a mean decayed, missing, filled teeth index of 2.89. A periodontal pocket of more than 6 mm was observed in 6% of the workers. Conclusion: The oral health of mine workers is in a poor state; steps should be taken so as to provide basic medical and dental care facilities.

Safety of the Train Control System become more important along with the progress of the computer and the technology of communications in these days. Safety of the Train Traffic Control System needs an accurate analysis of the Hazard to reduce losses of a property and lives. Many of advanced railroad nations already had established safety standards when they set the system even considering scrap of railroad and put a great concern on developing safety system which is getting larger and more complicate. Domestic railroad system has to introduce improved technology and systematically prepare and make a scientific survey to achieve unparalleled reliability and safety as well. In this Study, ITCC CTC System will show the research and the analysis of the hazard to ensure the safety of software.

One of the fastest-growing job categories for women in both the developed and the developing nations of the world is that of self-employment. In 1990 women accounted for 29% of all self employed workers. In Korea, self-employed women including unpaid family workers accounted for 40.4% of all female workers. They are in economically low status and have heavy workload. So, this study examines the real state and problems of self-employed woman. For this purpose, the transition of the number of self-employed women is nationally compared. And the statistical data and time use data on them and role conflict due to paid work and household work are presented. In the future society, self-employment will be a good alternative to self-realization and career for women. So, for self-employed women, following education is needed according to stages of business and characteristics of managers; entrepreneurship, management, and balance of work and family.
