Increasing ozone concentrations are observed over Japan from year to year. One cause of high ozone concentration in the Kanto region, which includes areas inland from large coastal cities such as metropolitan Tokyo, is the transportation of precursors by sea breezes. However, high ozone concentrations are also observed in the morning, before sea breezes approach inland areas. In this point, there would be a possibility of residual ozone existing above the nocturnal boundary layer affects the ozone concentration in the following morning. In this study, we utilized the Weather Research and Forecasting model and the Community Multiscale Air Quality model to evaluate the effect of regional precursors and residual ozone on ozone concentrations over the inland Kanto region. The results show that precursors emitted from non-metropolitan areas affected inland ozone concentrations more than did precursors from metropolitan areas. Moreover, calculated results indicate downward transportation of residual ozone, resulting in increased concentration. The residual ozone was also affected by precursors emitted from non-metropolitan areas.

Honam area is one of the under-industrial areas in Korea and because of this it has low weight in the total container transportation in Korea. Also the railway distance from honam area to the main container ports like Busan port and Gwangyang port is so short that the portion of rail container transportation occupies about 10 percent in total container transportation amount in Honam area. But on the contrary of those situations, 1st step Jangsung inland container depot (ICD) was finished as one of the main logistics facilities in Korea and 2nd Jangsung inland container depot is under construction. To promote rail container transportation in Honam area which has shortage of container transportation demand, it is necessary to give adequate transport service to the client. So, this research studied some methods for promoting rail container transportation in Honam area. The subject of survey is freight agent and survey items are selected to find the present situation of rail container transportation in Honam area. And from the survey results various strategies will be suggested to promote rail container transportation in Honam area.

China's 'One Belt One Road' initiative has had a profound impact on China's relationship with Central Asia, which shares borders at North-western region. Central Asia plays an important role in securing the export market of Chinese products, supply of raw materials, and transportation route to Europe. The inland port is of significance to facilitate the development of logistics, trade and industry in the surrounding areas by enabling the distribution and import and export clearance in the region by performing the role of the seaport on the hinterland. The purpose of this study is to analyze the effect of the development of inland ports in central and western China on the geopolitical relationship between China and Central Asia. To this end, we analyze the status of inland port development in China's Midwest by employing the SWOT-PEST analysis method to analyze the current status as well as prospects of trade, investment and transportation routes with Central Asia in terms of geopolitics. As a result of the analysis, the relations between China and Central Asian Countries are becoming more politically and economically close, but it has brought about serious challenges by domestic and foreign environmental changes. Therefore, the development of the inland ports in central and western China are determined by the geopolitical relations under 'One Belt One Road' initiative between China and Central Asia, while the development of the inland port is also expected to serve as a catalyst for the development of both regions.

Road and maritime transport which connecting main cities in the world is already fully saturated, and the loss cost caused by recent high oil prices is getting bigger. Transportation by inland waterway is rising as an alternative method of them. Concerning this, the GI Waterway is on construction to connect the Yellow sea and Seoul. Nevertheless, there are no existing aids to navigation around the area and no studies have been carried out for them. As the construction progresses, installation of proper aids to navigation should be considered and profound studies need to be carried out. This study focused on introduction of the cases and the systems of other countries inland waterway aids to navigation and suggested a suitable navigation aids system along the inland waterways in Korea and a way of installation for that system.

In the container transportation of inland depots the empty container is an important issue. The truck dispatching problem in this paper is considered under restriction about empty containers. When a full container arrives in a depot by truck, after unloading operation the full container is changed to an empty container. After loading operation an empty container is changed to a full container. We suggest an integrated approach to the problem of simultaneously managing empty truck and container movements. We suggest an integrated approach to the problem of simultaneously managing empty truck and container movements. We would like to find the truck dispatching method minimizing empty truck movements and empty container movements. In this paper, a mixed integer programming model is developed to obtain the optimal truck dispatching in container transportation and heuristic is developed to give a good solution in much shorter time. The numerical examples are studied and the proposed heuristic is also compared with the result of numerical examples.

Security systems for inland cargo truck transportation are mostly limited to route tracking for safe and efficient transportation. With this route tracking system, the status of cargo trucks can be monitored easily within inland boundaries. In case of oil transportation by land, however, security systems ensuring transportation of a designated quantity of products have been subject to extensive research since thefts and substitution by a similar product in the transportation process have emerged as a social problem. Security devices installed in an oil tank truck must meet the explosion-proof performance standards and be applicable to varying types of trucks. Accordingly, a wireless electronic seal with RF communication functions is considered to be the most appropriate method, but e-seals on moving vehicles require such levels of performance and reliability that can overcome certain challenges including changing radio waves and topographical impediments. Considering these characteristics of oil tank trucks, this study proposes an stabilization method to enhance the RF communication performance of e-seals, based on radio simulation and experiment findings.

자연경관이 우수한 도서지역을 찾는 관광객이 지속적으로 증가하고 있다. 또한 국민소득 수준과 여가시간의 증가로 장래 도서지역 관광객이 더욱 증가할 것으로 예상된다. 이들 관광객을 지원하는 관광교통의 측면에서 볼 때 연안여객터미널과 육상교통수단과의 연계교통 효율화는 매우 중요하지만 실상은 잘 이루어지고 있지 않다. 이는 연안여객터미널 위치가 육상교통수단의 터미널과 떨어져 있으며 이를 서로 연결해야 하는 시내버스 등 대중교통수단의 지원이 미흡하기 때문이다. 본 연구는 도서지역 관광 활성화를 위한 연계교통체계 개선 방향을 제시하였다. 주요 내용은 시내버스를 중심으로 하는 연계교통체계의 구축과 보행거리의 최소화, 도서지역 관광특성에 맞도록 여객선 운항계획의 조정, 관광객의 운임부담을 완화하기 위한 여객선의 대중교통화 방안, 교통수단간 시간적 공간적 연계 및 이를 통합교통정보로 제공하는 방안 등이다.
