This article aims to understand the meanings of urban regeneration utilizing culture and art focusing on a case of the waterfront development in Yokohama, and consider the role of culture and art playing in the cultural city strategy within the revitalization of regional cultures as a main intention by means of interrogation into the cultural policy and its practice in the waterfront development of a sea-port city. Yokohama has proceeded successfully the waterfront development through the creation of culture and art space by using the characterful and attractive urban scape and regional sources around the waterfront. In the cultural policy of 'the Creative City, Yokohama' as a part of 'Culture and Art Creatvie City' strategy of Japan, 'National Art Park plan' as a space planning policy realizes the regeneration of the waterfront through the creation of culture and art space. The examination on the basic intention of this venture and its practice helps comprehend a role of culture and art playing in the waterfront development of a sea-port city and shows the direction that the cultural policy would take in the waterfront regeneration.

Today, because the international community recognized happing of environmental crisis on the world the international environmental agreements and advanced country's environmental regulations are very tight. Especially, port cities are posed strong threats to the environment due to receiving high pollution from ships and cargo vehicle emissions. So many advanced country (ex. United States, Japan, EU) implement Natural-friendly Port Policy and Program. Environmental-Regulations become more stringent in the future, management of low carbon dioxide emissions brings the competitiveness.(중략)

In this letter, a new dual-port Multiple-Input Multiple-Output (MIMO) antenna is introduced which has two independent signal feeding ports in a single antenna element to achieve smaller antenna volumes for the 5G mobile applications. The dual-port structure is implemented by adding a cross coupled semi-loop (CCSL) antenna as the secondary radiator to the ground short of inverted-F antenna (IFA). It is found that the port to port isolation is not deteriorated when an IFA and CCSL is combined to form a dual-port structure. The isolation property of the proposed antenna is compared with a polarization diversity based dual-port antenna proposed in the literature [9]. The operating frequency range is 3.3-4.0 GHz which is suitable for places where $4{\times}4$ MIMO systems are supposed to be deployed such as in China, EU, Korea and Japan at the band ${\times}$ (3.3 - 3.8GHz. The measured 6-dB impedance bandwidths of the proposed antennas are larger than 700 MHz with isolation between the feeding ports higher than 18 dB [1-2]. The simulation and measurement results show that the proposed antenna concept is a very promising alternative for 5G mobile applications.

The 'One Belt One Road (OBOR)' initiative, which was promulgated as part of the enlargement policy along with the advent of Xi Jinping in 2013, is a policy to expand China's political and economic power externally through linkages with neighboring countries. China's overseas port investment plays an important role in the promotion of the 'OBOR' policy from the coast of China through maritime transportation routes from S.E Asia to Mediterranean and Europe. Since China's overseas port investment has been made from several factors such as political, economic, and military motives, it differs in purpose and character from investments made by private companies, such as Global Port Operators(GTO) which consider profitability first. This study aims to address future prospects and implications by analyzing the geopolitics of China's overseas port investment under the 'One Belt One Road' initiative. According to the results, China's overseas port investment is dominated by state-owned enterprises and political and security factors are more important than profitability. China's overseas port investment has been on a large scale in a short period of time, and China has faced with various problems both domestically and internationally. such as debt default, environmental problems, subordination problems from recipient countries and political and military confrontation with great countries such as United States, Japan and India etc.

This paper is the on-site case study of the shaping of townscape of port towns in Korea. Inchon has been experienced the rapid urbanization after the opening of a port. Inchon is selected because of the relatively rapid process, the apparent event and influence, and the enough referneces of data about the landscape formation and transformation. As the value of historical landscape, it is very significant to study Inchon and the causes of change in townscape depend on the external element-the opening of a port, Japan colonial policy, economic progress, nationwide development. The main purpose of this study is scrutinized the process, the cause and effect, and the contents and the form of shaping of townscape. The result of the interpretation of landscape is never perfect but only a starting point. Finally this study will be applied to the pragmatic task as a basic tool which construct the desirable image of the city.

The direct investment and export of Korean companies has increased to Russia. Korea and China have mostly accounted for the Russian far eastern port of import and export cargo since 2000, and the share of container volume from Vostochny port in 2009 was Korea(71%), China(26%) and Japan(3%) each countries. Like above mentioned, The development in TSR transportation has a huge significance in the position of Korea because Korea is actively utilizing TSR(Trans Siberian Railway) transportation. Therefore, this paper is to examine the development and prospects in Trans Siberian Railway transportation.

With the expansion of the global supply chain, the efficiency of maritime logistics is considered a crucial factor for countries' trade and competitiveness. Nevertheless, prior research has not thoroughly evaluated the efficiency of maritime logistics, including countries' ports and shipping capacities. Accordingly, this study examines integrated maritime logistics efficiency at the national level using DEA-CCR, BCC, and super-efficiency DEA. Furthermore, this study identifies a difference between the selected countries' maritime logistics efficiency and LPI (Logistics Performance Index) through Spearman's correlation test as an ad-hoc analysis. From this, Asian countries showed higher efficiency and European countries showed higher LPI scores. These results might be derived from this difference in port-city development patterns. Additionally, the main cause of inefficiency in Europe and Japan might be attributed to high fleet capacity of control. Consequently, this study can provide valuable implications for coastal countries to set more efficient directions for maritime logistics investment and policy.

It has been said from previous studies that the preconsolidation pressure (p$\sub$c/)of Nangton Rive. deposit is considerably less than the in situ effective burden pressure (p'$\sub$$\upsilon$ο/). Question has risen whether this small pc vale is due to under consolidation or unsuitable laboratory test including low small quality. As a cooperative research program between PHRI (Port and Harbor Research Institute) and Pusan National University, an extensive soil investigation was carried out at a site of Yangsan, Pusan, using the Japanese sampler. It Is found that although p$\sub$c/ value at the site is slightly greater than p'$\sub$$\upsilon$ο/, its over consolidation ratio (OCR) is quite small compared with aged normally consolidated clay in Japan.
