The purpose of this study is to gain knowledge on the spread of Photovoltaic in Germany. There are major differences between Japan and Germany in zoning, including building permits for PV installations and land use restrictions. Based on these, we will show the direction toward the spread of PV in Japan. The first point, Considering making all PV installation a registration system; The second point, Mandatory environmental impact assessment for ground-based PV in rural areas; The third point, Correspondence of cityscape conservation area of urban area utilizing landscape law; The fourth point, Ensuring high quality PV panels.

磁気計測による新規の化学・生化学センサの開発のために、磁性ナノ粒子を刺激応答性ハイドロゲルに内包した磁気ハイドロゲルをバイオセンシングのラベルとして創製した。磁性ナノ粒子の分散・凝集状態を制御するために、磁性ナノ粒子がpH等の化学的刺激に応答するハイドロゲル中に適切な配置で分散し、かつゲル中で物理的な回転・振動をすることができる、構造制御された磁気ハイドロゲルラベルである。pH応答性ゲルの膨潤特性の変化に伴い、磁性ナノ粒子の流体力学的振舞(物理的な運動)の変化を交流磁化計測により検出した。さらに、この磁気ハイドロゲルを用いて、交流磁化特性の計測によってアンモニアガスを検出することに成功した。

In this study we investigated the eye morphology and retinal topography of two owl species in relation to their visual environment. Although Short-eared Owl Asio flammeus is larger and weighs more than Japanese Scops Owl Otus semitorques, its eye dimensions (weight, corneal diameter, and axial length) are all smaller than the scops owl's. Owl retinas were examined in Nissl-stained whole-mount preparations. The total number of retinal ganglion cells (RGCs) was greater in the Japanese Scops Owl (4,703.0×103 cells) than in the Short-eared Owl (2,346.8×103 cells). The eye morphology of, and the number of RGCs in the Japanese Scops Owl indicate that it is more adapted to a nocturnal habit. An area of high-density RGCs was horizontally distributed in the temporal retina of the Short-eared Owl, with a peak density of 17.4×103 cells/mm2. In the Japanese Scops Owl's temporal retina, there was an oval-shaped arrangement with a peak density of 23.1×103 cells/mm2. These distributions indicate that whereas Short-eared Owl is adapted to open habitats, Japanese Scops Owl is adapted to enclosed habitats. The RGCs of both species were classified into three categories (small, medium, and large) based on the size and appearance of somas. In both species, medium-sized cells predominated, and the proportion of large-sized cells was smallest. The distribution and high-density areas differed among these groups, suggesting adaptation to the visual environment. The high-density areas of these groups cover the nasal visual fields, which include the overlap for binocular vision.

Wastewater containing tetrafluoroboric acid-hexavalent chromium was decomposed to fluorine (HF) and boron (H3BO3) in acidic conditions using excess aluminum sulfate at normal temperature. In subsequent processing, boron was separated by coagulation-sedimentation using ettringite and calcium hydroxide in highly alkaline conditions. This processing reduced the boron concentration to 10 mg dm-3 or less in the effluent standard. The ettringite used in this experiment was prepared using aluminum sulfate and calcium hydroxide. Alkaline filtered water containing aluminum ion and calcium ion was pH-adjusted to 6.5-7.0 for fluoride removal. This continuous process produced fluorine concentrations of 8 mg dm-3 or less in the effluent standard. Based on these experiments, we devised a practical advanced wastewater treatment system including processing of tetrafluoroboric acid using ettringite. The contents of this paper will contribute to solving treatment problems for metal surface treatment wastewater containing fluorine and boron, also help in the treatment of other industrial wastewater.

Background The Ca2+ regulatory proteins in the sarcoplasmic reticulum (SR) play a key role in the pathogenesis of heart failure. In the present study the effect of chronic β-receptor-stimulation on cardiac and SR functions was assessed, with or without angiotensin-II receptor antagonist treatment recently reported to have anti-β-adrenergic activity. Methods and Results Rats were treated with isoproterenol with (+) or without (-) candesartan (CAN) and then SR vesicles were isolated from the left ventricular muscle. Both Ca2+-uptake and the amount of SR Ca2+-ATPase were significantly lower in the CAN (-) group than in the shams, but those were almost normally restored in the CAN (+). Although the level of the protein kinase A (PKA)-phosphorylation of the SR Ca2+ release channel, known as the ryanodine receptor (RyR2), was elevated in the CAN (-), no Ca2+-leak was detected. However, SIN-1 (O2 - donor) induced Ca2+-leak in the CAN (-) at a 10-fold lower dose than in the sham and CAN (+). In cardiomyocytes, SIN-1 decreased cell shortening and the peak Ca2+ transient and prolonged time from peak to 70% decline in CAN (-), again at 10-fold lower dose than in the sham and CAN (+). Conclusion Chronic β-receptor-stimulation did not induce any Ca2+-leak from the SR, whereas Ca2+-leak was easily induced when oxidative stress was applied to the PKA-phosphorylated RyR2. Candesartan not only improved Ca2+-uptake, but also prevented PKA-phosphorylation, rendering the SR less susceptible to Ca2+-leak. (Circ J 2006; 70: 777 - 786)

日本海にある隠岐諸島では,氷河期の遺存的な樹種が暖温帯に生育するのが特徴である。氷河期遺存樹種の分布を調べた結果,北方系針葉樹のヒメコマツは山地の露岩地,クロベは海岸から山地まで,第三紀遺存種のカツラは渓流沿いに分布していた。冷温帯樹種のミズナラは海岸から山地まで生育するものの島の北側に偏って分布し,北西の季節風の影響により冷涼で降水量の多い環境が生育地となっていると考えられた。さらに,遺伝的多様性を調べた結果,クロベは隠岐諸島を氷河期の避難地とした可能性があった。隠岐諸島は日本の気候変動における樹木の変遷を知る上で重要な島嶼であるといえる。

This study examines the Social Department of Nagano Prefecture and the history of its establishment through material analysis based on an understanding of how society has worked in rural areas. Thus, the following points were clarified. First, in Nagano Prefecture’s administrative organization, the Social Department established in the administrative reorganization in 2010, traces its roots to the establishment of the Social Department in 1921. Second, after the abolition of the Social Department in 1938, there was no organization for society-related projects in the prefectural offices for about eight years before the establishment of the Ministry of Education and Civil Affairs in 1946 after World War II. Consequently, the Ministry of Education took over projects that were previously under the supervision of the Social Department. Third, after the Social Department was abolished in 1924, it was revived in 1926 to manage funds for the activities of Social Welfare Commissioners. Therefore, as a mechanism that underpins local social projects, the Nagano Prefectural Social Department has been one of the social security systems through repeated cycles of abolition, survival, and transformation before World War II. Hence, by referencing the Social Department, hints were obtained to elucidate how society was conceived.

ヒトの速度知覚は,刺激パターンの様々な要因(1)輝度コントラスト,(2)空間周波数,(3)形状などに影響を受ける.すなわち,パターンの速度が物理的に等しくても,知覚量としては異なることがある.この差は錯視量と呼ばれる.これらの視覚特性や要因を再現・説明するために,さまざまな視覚細胞特性や計算論的仮定などを導入した数理モデルが提案されてきた.本研究では,ヒトの視覚細胞特性や計算論的仮定を考慮・導入していない工学的画像処理アルゴリズムでも基本的な知覚特性が再現・説明できることを示す.具体的には時空間微分算法と呼ばれる手法の入出力特性を測定・分析・数理的考察を行い,上記(1)(2)(3)の視覚特性が再現・説明できることを示す.このような工学的観点から考察を行うことで,視覚特性の要因について新たな解釈を与えることを目的とする.具体的な手法としては,MATLABによるシミュレーションにより,上記の視覚特性の再現・説明を試みた.シミュレーションを行った結果,工学的画像処理アルゴリズムでも上記(1)(2)(3)の特性が再現できることを示した.さらに数理的な考察を行い,細胞ノイズ・生体ノイズなどのノイズが速度推定に影響を与え,結果として視覚特性が現れることを示した.また,刺激の形状や,物理的運動方向を定めることで,どの程度の錯視量が生じるか数式上で求められることを示した.これは,刺激の形状によって,錯視量が最大となる運動方向や,錯視が生じない運動方向を計算論的に定められることを意味している.この研究により,工学的観点から視覚特性が再現できることがわかり,視覚特性の要因についても新たな解釈,工学的考察の可能性を与えた.
