宮城協働モデルにおけるCloud for Innovative Teaching(CIT)システムの開発と活用

　本研究では，文部科学省の「地(知)の拠点プロジェタト(Center of Community)」にて，国内で唯一採択された教員養成大学として，宮城協働モデルによる次世代型教育の開発・普及に取り組んでいる。この中で，大学（学生, 教員)と地方自治体（学校，教育委員会)との協働により，学び続け質的向上を目指すイノベーティブ・ティーチャーを養成・育成している。その中核の「場」を提供するのがCIT(Cloud for Innovative Teaching）である。CITは， 「コミュニティ」機能，「データボックス」機能，そして「Multi-User Evaluation system(MUEs）」という3つの機能で構成されている。本学学生・教員および学校教育関係者のみが使用できるこのシステムにおいて，大学における教科教育法での活用や教育実習での活用を試行し，良好な成果を上げている

Plaque Assay Method for Adenovirus Type 5 with the Culture of HEK Cells Synchronously Infected with the Virus.

適宜に階段稀釈した抗血清とX×10^4 PFUのウイルスを混じ室温1時間放置した後,直ちに1:100まで稀釈する.この稀釈液と等量の維持に浮游させた2～3×10^6/mlのHEK細胞とを混和し,37℃30分間軽く振盪する.径5cmのシヤレーに1mlずつ入れ,細胞をガラス面に拡げ,0.5%仔牛血清,0.75%カルボオキシメチールセルローズを含んだ維持液を加え蔽う.5日ないし6日目に細胞をギムザ液で染色し,プラークを算える.以上が抗血清の中和抗体の測定法である.抗血清と抗原(分画その他)を加え充分反応させた後,更らにX×10^4PFUのウイルスを追加し室温60分放置し,以後の手順は上記の方法に従う,以上が抗原による抗血清中の抗体のブロック能を知る方法である.以上の方法を用いて,アデノウイルス5型の抗血清に対するA抗原,C抗原及びP抗原のブロック能を検査した.抗血清が完全にブロックされたのはA抗原によってのみであり, C抗原及びP抗原は抗血清のブロック能を有しないことを知った.The mixture of antiserum and antigen at each adequate dilution was added the seed virus contained X×10^4 PFU per ml. The mixture was diluted upto the concentration contained 50 to 100 plaques per ml per a dish and 2 ml of the last dilution was made. The last dilution of the mixture was added equal volume of HEK cell suspension contained 2 or 3×10^6 cells per ml and shaked at 37℃ for 20 or 30 minutes. One ml of these mixture of antiserum, antigen and seed virus was plated into a dish, and 4 ml of maintainance medium contained 0.5% calf serum and 0.75% carboxymethylcellulose was added and spread over in a dish. After incubation for 5 or 6 days, the cell sheet was fixed with 10% formaldehyde saline solution and washed and stained with Gimsa solution. The plaques formed in this method were clear and easy to count. The activity of antigen A, C and P of adenovirus type 5 for the blocking antibody against purified adenovirus type 5 was studied with the application of this plaque assay method

Regional Differences in Recreation and Tourism Activities owing to the Commodification of Rural Space in and around the Tokyo Metropolitan Area

　この報告では，首都圏とその周辺を含む15の都県の観光と農政の担当者から，それぞれの都県における農村空間の商品化による観光活動の種類と分布状況，そして地域差について聞き取り，さらに統計や既存の研究，そして観光パンフレット等の分析を加えて，現代社会で活発に行われているか，あるいはその潜在的可能性が高い，重要とみなされる観光活動を抽出した。それらは，散策と市民農園，農産物直売所・農家レストラン，観光農園，ハイキング，農林業・農山村生活体験，避暑，スキー，登山，そしてマリンレジャーの10種類であった。これらの分布に基づいて地域区分を行った結果，基本的には東京都心部を中心とした同心円状のパターンがみられた。それは，農村空間の商品化による観光活動は，主として大都市からの近接性や交通利便性によって，さらには自然環境や農林水産業の内容，既存の観光地の存在によって規定されるからである。Rural space in Japan is currently characterized by the increased role of consumption rather than the traditional activity of production, such as growing rice or other crops. This situation is often described as the “commodification of rural space”. Although the commodification of rural space can occur in various forms, recreation and tourism are the most visually appealing to people. The objective of this study is to examine how regional differences in central Japan affect the commodification of rural space for recreation and tourism activities. The study area ranged from the Tokyo metropolitan area (which contains the prefecture of Tokyo and three immediate prefectures) to 11 additional prefectures located in the central part of Japan. We visited the one main governmental office in each of the 15 prefectures to interview the officials in charge of tourism and agriculture, and asked them to identify important types of recreation and tourism activities owing to the commodification of rural space in their prefectures. We also asked them to show us typical rural recreation or tourism activities, in an effort to better characterize and divide the prefectural areas based on their experiential and subjective images of rural recreation and tourism. In addition to the experiential decisions of the officials, we examined the regional differences in recreation and tourism activities owing to the commodification of rural space based on our landscape observations and the analysis of statistics, previous studies, and tourist brochures. As a result, we chose 10 common types of rural recreation and tourism activities and examined their distribution and regional differences. Walking spaces were found in every prefecture but it was the most important and basic recreation activity in urban areas. While this provision of walking is typical of urban areas, allotment gardens were found to be dominant in suburban areas, and farm produce shops and farmers’ restaurants were typical in main plains where farming is thriving. In the same respect, “you-pick” farms were commonly found in fruit-growing basins, as was hiking in hills and low mountains, the availability of rural experiences in remote basins between mountains, and escaping the summer heat in highland resort areas. Mountainous areas offered downhill skiing in snowy areas and climbing in the higher mountains, while marine leisure activities were common in coastal and islands areas. These patterns formed concentric rings around the Tokyo metropolis. The differences in natural conditions, characteristics of farming, existence of current tourist sites, and proximity to metropolitan areas affect the commodification of rural space for recreation and tourism activities in central Japan

Study on the Boron-Nonstoichiometry and Properties of Perovskite-Type YRh3B

Polycrystalline samples ofYRh3Bx are prepared by the arc melting synthetic method. Perovskite-type cubic phase (space group : Pm3m) of YRh3 Bx exists in the range of 0.50 ≤x≤1. Lattice parameterαof YRh3Bx depends on x, and varies linearly from a = 0.416347(4) nm (x = 1.000) to 0.408776(7) nm (x = 0.500). The value of Vickers microhardness ofYRh3Bx ranges from 7.7 to 2.7 GPa. Hardness decreases with decreasing of boron content x. The TEM observation reveals that the anomalous softening of hardness in the vicinity of x = 0.5 for YRh3 Bx is caused by the appearance of the modulated structure. By the TG-DTA, oxidation of YRh3B1.ooo starts at 541 K. The weight gain by oxidation is 11.4 %. The oxidized product is mixed phase of YB03 and Rh. The densi!Y of states at the Fermi level, D (EF), of YRh3 B1 .ooo (20 at.%B) is indicated to be slightly larger than that of YRh3B0.706(15 at.%B)
