ABSTRACT：One of the reconstruction projects following the Great East Japan Earthquake is a project to move victims to higher ground. At the core of this project is whether the people could build a life and community after moving to higher ground. This research clarified the existence of jobs for which stable income could be anticipated and the work in community consciousness through retaining such jobs in settlements after moving to higher ground through local surveys of persons subject to moving to higher ground in 16 areas in Ogatsu-tyo, Ishinomaki City.

ABSTRACT : The Heisei Sanriku Tsunami caused by the earthquake off the Pacific coast of Tōhoku on March 11, 2011 has led to efforts to learn more about the horrors of tsunamis in the past in order to avoid the same suffering in the future. The tsunami stone monuments erected by the ancestors, stone monuments with lessons engraved on them telling how to take refuge, contribute by transmitting awareness of tsunamis to local residents. Some monuments in different places fulfill their function when natural disasters occur, while others do not, and local residents have not always abided these lessons. This study, based on fieldwork regarding such lesson stone monuments all over Japan, investigated the actual situation of lesson stone monuments; some of them were moved due to the construction associated with widening roads, and others that remained had weathered faces with letters that had disappeared.

ABSTRACT : In order to close the controlled disposal site at sea, the leachate quality must satisfy the Environmental Standards. However, it takes long time for stabilization process. In this paper, laboratory tests were carried out to investigate the variation of pH values of seawater mixed with fly ash, which has significant effect on the increasing of pH in seawater. As a result, pH values of seawater increased to more than 9.0 when hoisting only upper part of deposited fly ash with seawater with the volume ratio of 1:40. On the other hand, from the elution of the bottom part of the deposited fly ash, pH values of seawater slightly increased to below 9.0. Moreover, it was confirmed that fly ash with smaller grain size has more effect on the increasing of pH in seawater.

ABSTRACT : In this analysis, we developed a logit model to estimate the cargo flow of international ferries and RORO ships between Japan and Korea/Northern China by each region and export/import. Although the model doesn’t reproduce some regional cargo flow of international ferries and RORO ships, we developed a logit model that reproduces cargo flow of international ferries and RORO ships. And we confirmed that this model is useful to analysis of the cargo flow when a new international RORO ship line was opened.

ABSTRACT：According to the IPCC Fifth Assessment Report, it is predicted that such as typhoons and heavy rain to increase in the future. Due to increase of typhoons and heavy rain, it considered the frequency of flooding will increase. We shall create a hazard map in order to suppress the flood. In areas where high-resolution DSM is not developed to be used SRTM and GDEM, but SRTM and GDEM have missing values. In this study, we propose a simple method of correcting the missing values. Using this method, it is possible to correct the missing values in a wide range of global.

ABSTRACT : The objective of this study is to propose the mangrove distribution map in Myanmar coastal zone by using satellite remote sensing data based on the estimation method of mangrove area (Kuwahara et al. 2010). Global warming and sea-level rise are projected to affect seriously on low-land area. Therefore, recently, the mangrove forest is important to decrease the damage which is received from storm surge and sea-level rise. However, because of the mangrove forest distribution area decreases, it is thought that the monitoring becomes important to confirm the area. So we adopted this method to mangrove area extraction and verified the versatility of its method.

ABSTRACT: When large scale earthquakes and tsunamis occur, disposal of huge volume disaster rubble without delay is required. For the purpose, we assumed cases to construct a confined sea disposal facility in a place not far from damaged areas, and estimated and analyzed the numbers of days before receiving waste starts and the construction costs. To construct the sea disposal facilities in short period of time and at low cost, we assumed two construction methods. The first method is to transfer existing facilities to bulkheads of sea disposal facility in a long section. The second method is to build circumference bank with disaster rubble. After setting conditions, the numbers of days before receiving waste starts were estimated at 0.4 - 1.0 year from the start of the construction. Besides, 15 - 60% of the construction costs were reduced by using the construction methods, and the costs became superior or equivalent levels to those of land disposal facilities on suitable conditions. We surveyed disaster experience and found that for emergency construction of disposal facilities, its preparation and administrative procedure modification, e.g. port planning system, are considerably important.

Abstract: This paper aims to reveal the container shipping trends of Viet Nam focusing vessel flows and official container services to Viet Nam ports since 1995. Our approach is practical in order to obtain useful information for port operators and policy makers which play an important role for evaluating the degree of integration of Viet Nam ports with container networks. Our main findings are 1) Container shipping services to Viet Nam market have increased in both quantities (with larger vessels) and qualities (more frequent and reliable services). 2) Cai Mep ports emerge as a local hub port for cargo from South Eastern Viet Nam bounding for Transpacific and Trans Eurasian. 3) The shares of Hong Kong and Singapore decline with increase of direct shipping from/to Cai Mep ports. From our findings, we finally address two policy implications for enhancing the efficiency in container transport from/to Southern of Viet Nam: 1) shifting vessel flows to Cai Mep ports is necessary, 2) improving connectivity between Cai Mep ports and its hinterland is demanded.

The purpose of this paper is to clarify the overview of the structure and function of coastal management organization as a preliminary analysis. Recently, the number of Sato-umi, which is regarded as a type of integrated coastal management, has been increasing in Japan, but the overview has not been grasped yet. To achieve the purpose, we carried out literature survey and two types of questioner research. As a result, the number of coastal management in Japan was estimated as 232 cases. Furthermore, we could make the database of 103 cases through prefecture questioner researches. According to the database, the standard figure of coastal management organization is estimated like the follows; the main actors are the municipality government, the prefecture government, Fisherman’s Cooperative Associations (FCAs), and the central government. They become the management body or participate as a regular member. The form of the management organization is a council consisting of relevant organizations. According to the questioner research for cases, the working form of secretary possibly has relationship with the outcome of each activities.
