In the 2016 fiscal year, communication cases on general waste disposal facility construction plans in recent years were surveyed. Results suggested as follows: (1) Existing long-term relationships or agreements in local area promote local accepting. (2) An operator needs to consider alternative plans and explain reasons for the decision making to local stakeholders. (3) Even after first announcement of a new plan, an operator needs to review the plan depending on local concerns. (4) Announcement of a new plan will activate communications on local development including the site redevelopment.

JAEA Ningyo-toge Environmental Engineering Center and Fukushima Environmental Safety Center have same challenges in risk communication. As reference, similar domestic cases were investigated by our two Centers, and requirements for building long-term relationship were clarified. As follows; (1) Develop new relationship with various stakeholders in the region. (2) Make better use of existing resources (personnel, land and facilities, etc.). (3) Make a concerted effort to create new values with local stakeholders. (4) Make an opportunity which local stakeholders confirm safety and build confidence to the project. These efforts will enhance the opportunities for operators and residents to learn about environment management and environmental protection.

From 1955 to 2001, Japan Atomic Energy Agency (JAEA) carried out research and development projects related to uranium exploration, mining refining, conversion and enrichment at/around Ningyo-toge in Japan. Subsequently, JAEA has been conducting projects related to decommissioning of nuclear fuel cycle facilities and remediation of closed mine sites. JAEA had opportunities of communication with local stakeholders through the projects. Consensus building with local stakeholders and maintain it for over decades are important challenges for JAEA Ningyo-toge Environmental Engineering Center. For this aim, similar domestic case were investigated and compared, and evaluated about required measures for long term relationship with local stakeholder.

An understanding of the mechanisms responsible for formation or decomposition of GeO interlayer and Ge diffusion into high- layer is important to develop advanced metal/high- gate stacks for Ge MOSFETs. In this work, we fabricated HfO
/GeO/Ge gate stacks by 
oxidation of thin metal Hf layers on Ge substrates. The effect of plasma oxidation on the change in the bonding states of Ge atoms in HfO/GeO/Ge gate stacks and the structural changes induced by metal electrode deposition and thermal annealing was systematically investigated by synchrotron radiation photoemission spectroscopy (SR-PES) and electrical characterization.

J-PARC is a large scale facility of the proton accelerators for the multi-purpose of scientific researches in Japan. This facility consists of three accelerators and three experimental stations. Now, J-PARC is under construction, and LINAC is operated for one year, 3GeV synchrotron has just started the commissioning in this October the 1st. The completion of this facility will be next summer. The control system of accelerators established fundamental performance for the initial commissioning. The most important requirement to the control system of this facility is to minimize the activation of accelerator devices. In this paper, we show that the performances of each layer of this control system have been achieved in the initial stage.

Recently, researches of estimating a primary production are active by coupling an ocean general circulation model and a lower trophic level ecosystem model. This study aims to develop the vertically one-dimensional ecosystem model west of Hokkaido. The lower trophic level ecosystem model used in this study originates from the one-box NEMURO. It successfully reproduced spring and autumn phytoplankton bloom and maximum of phytoplankton concentration in the subsurface layer in summer.

Based on an operational ocean forecast system, a one dimensional lower trophic ecosystem model was applied for understanding seasonal and vertical variations of the primary production in the northern Japan Sea. The ecosystem model successfully showed realistic seasonal variations and their vertical distributions of nitrate, phytoplankton and zooplankton. For example, the spring bloom occurred with approximately 1.5
10
molN/l in early April from the surface to the depth of 50 m.

A three-dimensional lower trophic ecosystem model is applied to understand temporal and spatial variation of chlorophyll-a and nutrient in the Japan Sea. The lower trophic ecosystem model is driven by monthly solar radiation and daily temperature, current velocity and vertical diffusion coefficient calculated from the eddy-resolving ocean general circulation model. Satellite data of SeaWiFS on chlorophyll-a concentration at sea surface and long-term bimonthly data in the northern Japan Sea are used to validate model results. The lower trophic ecosystem model qualitatively reproduced seasonal variation of chlorophyll-a and nutrient. Spatial averages of correlation coefficient and RMS between the model results and the satellite-observed chlorophyll-a are 0.455 and 1.468 mg/m
, respectively.
