Due to the industrialization and urbanization, the transport of hazardous materials increases, which rises possibilities in occurring prospective accidents in terms of hazardous material transport as well. This study applied the model developed from the previous research to analyze the scale of damage areas from the accidents related to hazardous material accidents, as well as suggested a method to measure automatically the scale of accident including casualties and environmental damage based on the guideline which suggests the quantities of hazardous materials exposed from an accident and was defined in the study of standardization for hazardous material classification. A buffering analysis technique of Geographic Information System (GIS) was applied for that. To apply the model which evaluates the scale of population and exposure to environment on each link, rail network, zones, rail accident data, rail freight trips, and locations of rivers etc were complied as a database for GIS analysis. In conclusion, a method to measure damage areas by the types of hazardous materials was introduced using a Clip and a Special Join technique for overlay analysis.

본 논문에서는 컨테이너의 육상, 해상 수송간 안전운송을 위해 CSD 시스템에 기반한 응용 서비스 개발에 대해 기술한다. CSD 시스템에 기반하여 표준에 따른 응용 서비스 및 보안 서비스의 개발과 개발결과의 테스트 과정에 대해 기술하였다. CSD에 의한 보안기능 외에 운송중의 재난 예방을 위해 온도, 습도 및 충격센서를 이용한 컨테이너 화물 상태감시 기능도 개발되었다. 응용 서비스와 CSD 시스템간에 교환되는 메시지 기밀성을 위해 데스크탑 PC 이상의 시스템 환경과 8 bit CPU 환경에서 각각 RC5, AES-128 알고리즘에 따른 암/복호화 기능을 구현하였다. 암/복호화 시간에 대한 측정 결과, 두 알고리즘 모두 사용 가능함을 확인하였다.

This paper discusses several topics associated with the densification caused by supertall buildings and their impact on city systems. The paper covers five key areas where a supertall tower creates a concentration of needs and effects. First, the paper comments on population shifts towards the city and how they affect carbon footprint, utilities infrastructure and transport. The effect of single- and mixed-use towers is discussed in the context of population density. The second section brings the issues of transit, accessibility and master planning into focus. The use and criticality of public transport, cycling and walking is described. Servicing and deliveries using freight consolidation and shared systems is also discussed along with their contribution to the culture of sustainable travel. In the third section the paper reflects on supertall buildings' below-ground utilities and drainage provision, particularly the challenges faced in established city infrastructures. The utilities issues associated with supertall concentration (in land-use terms) compared to equivalent low-rise distribution is also commented on in the context of surface water runoff. In the fourth section, the topic of supertall sustainability is discussed and how city systems need to respond to create desirable and affordable space for occupiers. The changing need for vertical communities, 'stacked neighbourhoods' and the notion of a micro-city is described. Finally, the paper considers the energy consumption and resilience of supertall buildings in the context of basic geometry, façade design, climate and mixed-use benefits as they impact city systems.

The decline of railway industry been a world-wide phenomenon. Recently, increased attention has therefore of railway systems has considerable impacts on the existing transport systems. Korea is expecting a era of high-speed railway and thus the need for the preexamination of such system emerges. This study is therefore concerned with the impacts on the conventional railway systems of the planned high-speed railway and its policy implication. The results revealed that the high-speed railway is almost exclusive to the conventional railway system emerges. This study is therefore concerned with the impacts on the conventional railway systems of the planned high-speed railway and its policy implication. The results revealed that the high-speed railway is almost exclusive to the conventional railway systems. The only impact is to induce some users of the conventional railway services, resulting in some excess track capacity of Kyungbu line. It dose however appear not to have any influence on the level of service for the conventional passenger services and rail freight transport. Consequently, it appears desirable to pay as much attention to the conventional railway systems as to the high-speed railway.

This study analyzes the effects of road transportation networks on the local economy in korea. The analysis methods are SNA and spatial panel regression model. The subjects of this study are inland areas of Korea, and the research period is from 2010 to 2019. The network analysis showed that the connection centrality of Gyeongg-do was high internally and externally. Gyeonggi-do has played a central role in the domestic road freight transportation industry. The results of spatial panel regression analysis showed that there was economic competition between regions. Domestic road transportation industry has been competitive among regions and has economic ripple effect. And Internal cargo has been shown to boost the economy of the region. But internal cargo has been shown to lower the economy of surrounding regions, but external cargo has been shown to increase the economy. In order to revitalize the local economy, it is necessary to increase road cargo.

The maritime industry, responsible for 80% of global freight transport, heavily pollutes the environment through traditional fossil fuels. The International Maritime Organization aims to reduce sulfur and greenhouse gas emissions, but faces technical and financial challenges. Hydrogen fuel cells present a promising alternative with high efficiency and low emissions. This study examines the legal and regulatory frameworks needed for hydrogen bunkering across land, port, and sea. Key legislation includes the High-pressure Gas Safety Control Act, Hydrogen Economy Promotion and Hydrogen Safety Management Act, Harbor Act, Harbor Authority Act, Marine Transportation Act, and Harbor Transport Business Act. The study identifies overlapping regulations and proposes integrated solutions. The findings underscore the necessity of strict safety standards and legislative amendments to recognize hydrogen as a ship fuel. Establishing a comprehensive legal framework is essential for safe and efficient hydrogen bunkering. Continuous updates through international cooperation and standardized regulations are crucial for adopting hydrogen fuel cells, ensuring a sustainable and environmentally friendly maritime industry.

국내 원자력발전소의 사용후핵연료는 소내저장시설에 보관되어 있으나 저장시설의 용량 확장이 어려움이 있으며, 연구기관의 연구로에서 발생하는 고준위 방사성폐기물도 자체 보관중이나 영구적으로 저장할 수 없다. 또한 원전의 해체 시에도 고준위 방사성폐기물이 발생할 것으로 예상된다. 이에 따라, 본 연구에서는 현재 개발된 사용후핵연료 운반용기를 사용하여 고준위 방사성폐기물을 가상의 관리시설로 철도를 통하여 운반하는 경우에 대하여 작업자 및 운반경로 주변 일반인의 예상 피폭선량을 평가하였으며, 그 결과를 국내 법적기준치와 비교하였다. 또한, 고준위 방사성폐기물의 상하차 작업 시 작업자와 운반용기 간 거리와 운반사고 시 방사성핵종의 누출율의 변화에 따른 피폭선량의 변화에 따른 피폭선량 추이와 운반에 사용되는 열차의 구성에 따른 운반작업자의 피폭선량 변화를 분석하였다. 본 연구에서 설정한 모든 조건에서의 예상피폭선량은 국내 법적제한치 이하임을 확인하였다.

The convergence of fixed and wireless networks in data communication is providing the necessary driver for M2M commerce to take-off. The opportunities provided by M2M Commerce areonly limited by imagination. Automotive Fleet and Freight, Tolling, Water and Power Metering, Supply Chain Management including Asset Management, Remote Monitoring and Diagnostics, Energy Management and Access Control and Security are among the many M2M applications that are currently getting rolled out. ARC Group expects the worldwide solutions market to be worth in excess of US$ 100 billion by 2007. In addition, operator revenues worldwide from the transport of Telematics data alone will rise from US$ 3.5 billion in 2002 to US$ 78 billion by 2007. This paper discusses some of the lifestyle and business opportunities provided by M2M Commerce in the new ear of network convergence. It also provides some case studies to demonstrate the benefits of M2M Commerce across the supply chain. The key focus of the paper is on achieving enhanced lifestyle, cost reduction, improved profitability and enhanced customer relationship management through M2M Commerce.
