연강(mile steel)은 철도차량 차체의 주요 재질로 오랫동안 사용되어 왔으며, 다양한 강도 특성과 저렴한 가격, 용이한 작업성등의 이유로 현재까지도 널리 적용되고 있다. 그러나 연강은 부식에 취약하므로 도장작업이 필수적이고, 부식에 대한 여유로 인해 판두께의 감소가 제한적이므로 경량화가 곤란하고, 정기적인 유지보수가 필요한 단점이 있다. 반면에 스테인레스강(stainless steel)판재는 내부식성이 강하므로 무도장이 가능하고, 차체의 내구 수명이 증가하며, 유지보수가 편리하다는 장점이 있다. 또한 내부식성과 고강도 특성으로 차체 판재의 두께 감소가 가능하므로 경량화에 유리하고, 차체 표면의 다양한 표면처리가 가능하므로 외관의 미려함을 높일 수 있다. 스테인레스강는 연강에 비해 상대적으로 고가의 재질이지만 유지보수 측면과 경량화에 따른 운행비용 측면에서 볼 때 철도차량 차체의 재질로서 유용성을 가지고 있어 활발히 적용되고 있다. 국내에서는 1990년대초 과천선 전동차를 시작으로 스테인레스강 철도차량이 본격적으로 개발되어 상용화되었고, 새마을호를 비롯한객차에도 스테인레스강 차체를 적용하고 있다. 국내의 스테인레스강 철도차량 제작 기술은 이제 상당한 수준에 올라와 있으며 차량의 해외 수출은 물론 기술 이전도 활발히 진행되고 있다. 본 강좌에서는 스테인레스강 철도차량 차체의 특성과 함께 설계 방법을 정리하여 봄으로써, 향후 스테인레스강 철도차량 차체의 개선 및 발전을 위한 기초로 삼고자 한다.(중략)

South Korean universities have the common prevalent problem of significantly declining student populations. This study aims to explore the management strategy behind how the two South Korean maritime universities (Korea Maritime and Ocean University (KMOU) and Mokpo National Maritime University (MMU)) in particular, can solve the above problem by achieving internationalization through Twinning programs, taking advantage of their specialties in shipping and shipbuilding to export South Korean maritime education overseas. Twinning programs will also allow the universities to achieve the internationalization of their management, the globalization of their students, and the strengthening of the international competitiveness of the South Korean maritime industry. To achieve the above aim, this study will conduct a literature review on the internationalization background of general domestic and foreign universities. This study will also try to grasp the reality of, the obstacles to, and the factors that will accelerate the internationalization of the South Korean maritime universities. Finally, this study will research and propose directions the South Korean maritime universities can take to achieve pragmatic internationalization that comply with the current law on the export of higher education. This will be done by exploring the current status and trend of other universities' attraction of foreign international students, the legal feasibility and activation measures of the co-operation of curricula, and the researcher's own experiences.

This study is to clarify regional structure and connection of international physical distribution through clearance depot of Cheongju customs of inland location. The trade of clearance depot of Cheongju customs industrial characteristics reflects of territorial hinterland. As origins and destinations of freight as exports and imports region, territories of Cheongju customs trade mainly with Japan, China, and USA. Origin and destination of freight of Cheongju customs territory are hinterland and foreland of Incheon International Airport and Busan port. In case of export, foreland of Busan port is board, and in case of import, the hinterlands of Incheon International Airport and Busan port are similar. Clearance depot of inland-located Cheongju is construct by the advantages of rapidness and inexpensive cost. And the kind of freight and system of physical distribution of each enterprise show different characteristics. For each export and import freight, each shipper corporation has its own physical distribution system, and structure of international distribution is classified into export pattern of bonded industry and bonded warehouse. Again the patterns of bonded warehouse are distinguished free on board price system with division of labor in base of production in overseas, free on board price system, and cost-insurance-freight with division of labor in base of production in overseas. These Phenomena are caused by transaction between headquarter and its overseas corporation, initiative freight handling of export corporation, choice of inexpensive cost, and international convention.

During 40 years, clothing industry which took a charge of a pivotal role to lead Korea's economy development falls in a harsh state to maintain an international competitiveness by means of low wage-based-export and tech-deficit-past competitive advantage. From January first 2005 when the World Trade Organization started that developed countries abolished import quota on textile and apparel products. Therefore, the purpose of this study is to analyze Korea's apparel international market share, grasp Korea's apparel international competitiveness position, and examine the export features to enhance international competitiveness. We targeted members of Korea Apparel Industry Association among the 500's exporters of textile and clothing items in 'The Import and Export Textile Product 2003' Total 70 sheets were used of final data analyzing. Also, the statistical data of WTO wereselected for inquiry about the position of international competitiveness of clothing products made in Korea. First, the comparative analysis of the amount of export and international market share of each country's clothing products to capture the position of Korea's international competitiveness of clothing industry under the statistical data of WTO showed that Korea's international market share has been decreasing since 1989, and ranked in the 19th showing 1.31% in 2004. Second, as concerned with Korea's clothing export features, the experience of clothing companies in Korea was uniformly distributed like less than 10 to 30 and more than 30 years and knitted and woven male and female wears which cost mid price were exported to U.S.A. and Europe and Japan. Export items wereusually manufactured by Original Equipment Manufacturing way and directly exported through an exclusive responsible part for export.

최근 들어 내수용 및 수출용 자동차 보증 제도를 살펴보면 부품에 대한 방식 보증기간이 점차 연장되는 추세이며, 이에 따라 자동차사에서 요구하는 방식 및 내식성 평가 기준이 상향되어 가고 있다. 실제로 수출차에 대한 방청 품질 보증기간이 차체 구멍 발청 10년에서 12년으로 연장할 움직임을 보이는 등 점차 방식에 대한 관심이 높아지고 있다. 따라서 내식성 향상에 대한 끊임없는 연구가 지속적으로 이루어지고 있으며, 내식성 향상을 위해 구조/형상 변화, 도장 품질 향상, 최적화 설계 등 다방면에서 노력을 기울이고 있다. 그 중에서도 가장 근본적인 해결책인 소재의 내식성 향상에 대한 관심은 날로 높아지고 있는 실정이다. 특히 일본 등지에서는 GA 도금재의 사용이 증가하고 있으나, 아직은 내식성에 대한 효율적이고 체계적인 관리가 부족한 면이 있다. GA재는 합금화 과정에서 야기되는 Fe% 합금화도, 합금화 상분율(감마, 델타, 제타상), crater 등 복잡한 소재의 특성으로 인해 소재의 내식성 분석에 고려할 사항이 많다. 실제 여러 실험들을 통해서 GA재가 내식성에 영향이 있는 인자들에 대해 많은 연구가 진행되었지만 명확히 정량화되어 있지 않은 관계로 GA재의 내식성 관리 기준에 대해서도 명확하진 않은 상황이다. 본 연구에서는 당사재와 타사재의 고강도 GA재 (>440 MPa) 11종에 대해 crater분율, zeta상, 합금화도, 도금량 등의 다양한 도금 물성들을 조사하였다. 또한 이 시편들을 34일 동안의 복합염수 분무법(CCT)을 통해 얻은 최대 및 평균 블리스터 폭과 소재 표면품질 물성과의 상관관계를 통해서 부식과 연관된 관련인자들을 도출하고 정량적인 관계를 살펴보았다. GA재의 경우 다양한 물성들 중에서 도금 크레이터, 제타상, 합금화도 순으로 내식성에 영향을 주는 것으로 확인이 되었으며 이 세 인자들을 내식성 평가 지수화하여 GA재 생산시 효율적인 관리범위를 지정하는데 이용 가능할 수 있도록 diagram을 도출하였다. 따라서, 본 연구를 통하여 자동차사에서 요구하는 내식성 기준을 만족하기 위한 내식성 상관 인자들의 관리 수준을 정량화함으로써 보다 우수한 소재의 관리를 할 수 있도록 하고자 한다.
