A method of structural synthesis is proposed to set disposed shape of a flexible frame within an allowable region. Members of the flexible frame, which are initially straight, are discretized into straight bar segments linked by virtual coil springs at nodes. Assuming total strain energy is independently separated into two contributions of bending deformation by the springs and rectilinear deformation by the segments, we find positions of the nodes in the disposed state by means of the Lagrange multiplier method that searches for a stationary point of the total strain energy under the constraints on geometrical boundry conditions. A new formulation of the sensitivity analysis is derived to approximate the change of the found nodal positions with respect to design variables in the first-order sense. A layout constraint to exclude all the nodes from convex prohibited regions in disposed state yields governing equation of design variables in the form of linear simultaneous equations with rectangular matrix of coefficients, which is dealt with by the Moore-Penrose generalized inverse. A numerical example concerning with Y-shaped frame whose disposed shape is constrained by three prohibited regions demonstrates the validity of the proposed formulation.

The efforts on material recycling conducted by Oki-town, Fukuoka-prefecture, have been reported through many preceding studies for its framework and results. The efforts of Oki-town have been extended beyond just “waste reduction programs”, to the town development project based around material recycling. The perspective of their efforts has not been summarized because of its diverse project contents. Thus, we made anattempt to summarize the whole image of the recycling project conducted by Oki-town.

Pseudo global warming experiments (PGW) were conducted with 1000m and 500m horizontal resolution for the 2012 Kameoka extreme rainfall event, which was the type of back-building convection system. As a result, the back-building system was very well represented in both of present and PGW experiments, and the rainfall intensity and total rainfall increased in PGW experiments. This is due to the fact that: in the future, the amount of condensation in cumulonimbus will increase and a convective unstable field will be realized (meso γ ~ β), the back-building structure will be strengthened (meso β), and the convective unstable atmosphere was continuously supplied from the south (meso α). We also showed that the result of 500m resolution can represent the back-building system much better than that of 1000m because 1000m resolution can capture future changes in meso-α, but cannot capture changes smaller than meso-β sufficiently.

和文：2000年代に入ってから欧州を中心に再生可能エネルギーの急成長が始まった。特に欧州各国では、化石燃料の削減のみならず原子力発電への限界も見据えて、100％再生可能エネルギーに向けた歩みをすでに始めている。2011年の福島第一原発事故をきっかけに日本においても再生可能エネルギーへの転換が急速にすすみつつある。そこで本論文では、再生可能エネルギーの普及政策の中で特に固定価格買取制度（以下、FIT 制度）等の果たしてきた役割とその評価について、海外と国内を比較しつつ、国内での現状と今後の見通しを論じる。その上で、地域における 100％再生可能エネルギーへの展望として、最終的に将来目指すべき100％再生可能エネルギー地域への取組みと可能性を論じる。長期的な100％再生可能エネルギーの実現向けては、中長期的な導入目標の設定が重要だが、再生可能エネルギーに占める割合や温室効果ガス削減目標など、欧州各国では2020年までに30％を超える野心的な目標を掲げる国が多数ある。さらにドイツを中心に 100％自然エネルギー地域の実現のため取り組みが行われている。その際には、電気だけではなく、熱利用や輸送燃料についてもエネルギー効率化と再生可能エネルギーへの転換が重要である。一方、日本では2012年からのFIT制度の導入により太陽光発電を中心に急成長を始めたが、100％再生可能エネルギーに向けた動きとして福島県のビジョンやエネルギー永続地帯での評価などがある。 ; 英文：Rapid growth of renewable energy in Europe and from the 2000s began. Especially in European countries, the limit of nuclear power generation is not the reduction of fossil fuel only be anticipation, have already started to walk towards 100% renewable energy. In Japan in the wake of the severe accident of Fukushima Daiichi Nuclear Plant of 2011 is progressing rapidly conversion to renewable energy. In this paper, especially feed-in tariffs (FIT) in the dissemination policy of renewable energy and the role that has played such as for the evaluation, while comparing the overseas and domestic, and the future status quo in Japan We discuss the outlook. On top of that, as the outlook to 100% renewable energy in the region, to discuss the efforts and possibilities to 100% renewable energy region and should aim ultimately future. Toward the realization of long-term 100% renewable energy, medium- and long-term introduction goal setting but important, such as the percentage and greenhouse gas reduction targets as a percentage of renewable energy, in the European countries 30% in 2020 country listed an ambitious goal that exceeds a certain number. In addition it has been made efforts for the realization of 100% renewable energy region around Germany. In doing so, not only electricity, is also important conversion to energy efficiency and renewable energy for heat utilization and transportation fuel. ...

和文：本論考の目的は、稲作を事例に事故から4年の放射能対策を検証し、その成果と課題を検証しながら、「緊急時対応」から「恒常的対策」への質的転換を図るための視座を獲得するとともに、持続可能で体系立った放射能対策をトータルに提案する事である。特に、本研究では今日の放射能対策が機能不全に陥っていることの原因を、食料循環系における①物質循環過程、②食料生成過程、③流通消費過程が、それぞれ個別分断的に捉えられ、対策の中での「連続性」や「連動性」が欠如しているという構造的要因に求め、食料循環系内での連続性や連動性を高め、真に持続可能な対策へと質的転換を遂げるための課題を明らかにする。 ; 英文：One of the major effects of the nuclear accident at the Fukushima Daiichi Nuclear Power Plant was the radioactive contamination of agricultural fields, and foods made in contamination Area. The chapter first explains the mechanisms whereby rice plants absorb cesium, a major radioactive substance released by the accident. This chapter then discusses the importance of the measurement and mapping of radioactivity in soils, the implementation of cultivation methods that reduce the transfer of radioactive substances to crops, and the development of radioactivity monitoring systems for agricultural products. In particular this chapter highlights the importance of linking the cultivation-level strategies, including mapping and radioactive absorption mitigation, with the distribution-level strategies, such as agricultural product inspection.

In this thesis, we consider dimensionality reduction of parameters in a piecewise linear model of boost converter with PV input. The circuit is subject to a bi-objective optimization problem where the first and second objectives evaluate efficiency of input power and stability of periodic orbits, respectively. A trade off exists between the two objectives and is represented by a Pareto front. An approximation of the Pareto front is a criterion for the dimensionality reduction. Performing precise numerical experiment, a simple dimensionality reduction from two-dimensional parameter space into a one-dimensional parameter subspace is achieved.

In this study, we analyze the mechanism of the future change of a occurrence frequency of Guerrilla-heavy rainfall in the Kinki region in August by focusing on the future change of lapse rate and water vapor inflow using a 5km-mesh regional climate model (RCM05). From the analysis, we show the frequency of days will increase when Showalter Stability Index (SSI), which expresses atmospheric stability, becomes lower in the Kinki region in late August although lapse rate will decrease. Lower SSI means that atmosphere is unstable. Then we show that the reason of destabilization of SSI is the increase of water vapor in lower layer. Finally, we use Self-Organizing Map (SOM), which is one cluster classification method, to reveal the main reason of the increase of water vapor in the lower layer in late August. The results show the wind field which blows from the Pacific to the Kinki region is increasing, and this explains rich water vapor flux is supplied to the Kinki region.

Ethanol, 0.8 g/kg or 1.6 g/kg was administered to mice and exposed to mercury vapor ((203)Hg(0)) with the control mice which did not receive ethanol at the concentration of 0.1-0.5mg/m3 for 10 minutes. The exhaled mercury, urinary mercury, mercury in the blood and organ distribution of mercury after 1 hour of exposure of mice administered ethanol compared with those of control mice. The results obtained were as follows. 1. The amounts of exhaled mercury in the mice treated with ethanol were more than that in control mice; and the exhalations of human who receive ethanol will overestimate the true concentration of exposure in the Biological Monitoring. 2. The mercury concentrations in the blood of mice treated with ethanol were less than the control mice. The bloods of human who receive ethanol underestimate the true concentration of exposure in the Biological Monitoring. 3. The concentrations of mercury of urine corrected at a urinary density of 1.024 in mice treated with ethanol at 0.8 g/kg is more, and at 1.6 g/kg is less than the control. The urines of human who receive ethanol in low quantity will overestimate and in high quantity will underestimate the true concentration in the Boilogical Monitoring. 4. The concentrations of mercury of urine corrected at a urinary density of 1.024 have a significant regression to the mercury concentration in the kidney and not to the blood in all group (ethanol and control).

Sunflower oil has different two types of the fatty acid composition, high oleic acid type and high linoleic acid type. In this study, to clarify which type is better as a biodiesel feedstock, the combustion characteristics of high oleic sunflower oil methyl ester (SfME-ho) and high linoleic sunflower oil methyl ester (SfME-hl) were investigated using a DI diesel engine. SfME-ho and SfME-hl have same thermal efficiency and similar exhaust emissions compared with rapeseed and soybean oil methyl esters. SfME-ho has lower pour point, shorter ignition delay and lower HC, CO and NOx emissions compared with SfME-hl. From the experimental results, it is concluded that SfME-ho is better alternative diesel fuel than SfME-hl.
