Recently, the cyber-physical-system (CPS) has attracted great interest in the information and communications technology (ICT) research field for the virtual test of wireless communication systems. Since the performance of wireless communication significantly depends on the radio propagation channel characteristics, the development of accurate radio propagation simulation technology becomes essential for the purpose. This paper proposed the scenario-specific radio propagation simulation method from LiDAR point cloud data. By the continuous environment measurement by LiDAR, the positions of dynamic objects like pedestrians are tracked, as well as the site-specific propagation environment characteristics and their influences are taken into the simulation. For performance evaluation, the radio propagation measurement was conducted in the 28GHz band in an indoor office. The result showed a significant improvement in the RMSE of received power prediction. The proposed method will be utilized for the radio channel emulation in the CPS.

Two studies using the minimal group paradigm were conducted to investigate the intergroup discrimination in an experimentally created minority and majority groups. In both studies, subjects were divided into the minority and the majority group by drawing lots, and asked to allocate points between other ingroup members and outgroup members. In the first study, it was found that the minority group showed significant ingroup favouritism whereas the majority group did not. The minority group was more aware of their membership in the group than their counterpart. In the second study, subjects were led to believe that the minority group and the majority group had either similar or different social attitude. On the whole, both the minority and the majority group favoured a similar group and discriminated against a dissimilar group. The effects of attitudinal similarity in minimal groups were discussed.

The purpose of this study is to clarify the function and the part of the reutilized ruins of roman amphitheater in the process of formation of italian cities. This paper is to clarify the general outline of this phenomenon with a classification of the 40 samples in 39 roman cities according to the four functions : "fortress", "house", "religious building", "public buiIding", showing a chronological chart of the functions. Particularly the function as a "fortress" is analysed by four factors : "fortification for the reinforcement of city defence in the latter term of roman imperial times" (3C-5C), "fortification for the domination of the city by another nations" (5C-9C), "fortification for the reutilization of ruins as housing" (11C), "fortification for the reinforcement of city defence in the latter term of medieval times" (11C).

Hachijo Island, located on the volcanic front of the Izu-Ogasawara (Bonin) arc, consists of two stratovolcanoes : Nishiyama and Higashiyama. Nishiyama (Alt. 854.3 m) is a scarcely dissected cone called “Hachijo-fuji”. Nishiyama began its volcanic activities about 10, 000 years ago. Many lateral volcanoes exist around Nishiyama, and one of them, Kandoyama (Alt. 194.9 m) is a tuff cone which was formed by a phreatomagmatic eruption. This study discusses the stratigraphy of deposits, and the eruptive types and the eruption ages of Nishiyama after the formation of Kandoyama. The results are summarized as follows.1) This study names four air-fall pyroclastic materials “Ny1-4”, which erupted from Nishiyama after the pyroclastic surge eruption of Kandoyama (ca. 2, 500 y.BP). All of them are scoriaceous.2) Ny2 erupted from a lateral volcano on the west of Kandoyama. This scoria cone is composed of agglutinate.3) Ny3 erupted from the summit crater of Nishiyama ca. 1, 100 y.BP. Ny3 was widely distributed on the southeast flank of Nishiyama, but it did not reach the foot of Higashiyama. Prior to the eruption of Ny3, a large amount of lava flowed down the southeast flank of Nishiyama.4) Ny4 erupted from a crater row along the southeast side of Nishiyama. From the description found in archives, it is clear that the eruption of Ny4 corresponds to A.D. 1605 (Keicho 10th) eruption. Ny4 deposited around the vents as agglutinate, and air-fall materials were widely distributed on the southeast side of Nishiyama. However, the total volume of Ny4 was the same or less than that of the Miyakejima 1983 eruption and the Izu-Oshima 1986 eruption.5) There are descriptions in the archives of at least four eruptions and about ten occurrences of earthquakes and tsunami in and around Hachijo Island. The fissures and tsunami deposits which followed historic earthquakes were found at the Yaene site located on the south side of Nishiyama. The pyroclastic materials from Nishiyama date these past earthquakes.

1990年代以降,日本各地で新たな「中華街」の建設が実施され,あるいは計画段階で頓挫した例もみられた。本稿は,これら両者がモデルとした横浜中華街の成功要因の究明を通して,日本における地域活性化におけるエスニック資源の活用要件について考察した。まず,屋内型中華街として,立川中華街,台場小香港,千里中華街,および大須中華街の四つの例を取り上げ,それぞれの設立の背景や特色,閉業の経過・要因などを検討した。次に,構想段階で消滅した中華街として,仙台空中中華街,新潟中華街,札幌中華街,苫小牧中華街,福岡21世紀中華街を取り上げ,構想に至るまでの経過や問題点などを検討した。これらの検討を受けて,地域活性化におけるエスニック資源活用の成功事例として,横浜中華街の観光地としての変遷とその背景などについて考察した。以上の結果,エスニック資源を活用した地域活性化には,エスニック集団,ホスト社会,そして行政の三者の協力関係の樹立が不可欠であることが明らかになった。

椎間板ヘルニアなどの退行性疾患に対するMRIの意義は,椎体椎間板などの形態評価と腫瘍などの他疾患除外とされてきた.ペインクリニック医にとって最も重要である疼痛責任部位の同定は神経学的評価に委ねられてきたが,大きな進歩を遂げた現在のMRI技術と最近の知見を踏まえた読影を行えば,画像側からの疼痛責任部位の推定もある程度可能と思われる.撮影に関して重要なのは,連続撮影と脂肪抑制T2強調画像であり,読影に関して重要なのは詳細な解剖学的検討に加えて,椎間板突出部の信号,椎体信号,末梢神経所見,傍脊柱筋信号の確認と考える.

脊椎疾患の診断において,画像検査は問診や身体所見から推察される疾患や病態を確認する手段である.現在の画像機器のほとんどが身体から取り出した情報をコンピューターによってデジタル化処理し画像へと再構築しているため,その過程においてさまざまなノイズやアーチファクトが入り込む危険性があることに留意する.また,再構築された画像を過剰評価してしまうという危険性を常に有していることに留意する.単純X線像は脊椎の配列や,不安定性を見るのに適している.X線CTは骨や骨化巣の描出に適している.MRIは軟部組織の描出に適している.X線CTとMRIは相補的であるため,両者をうまく組み合わせることで正確な診断につながることが多い.

本稿では,福島原発事故に立ち上がった,市民による放射線計測活動を広く見渡し,それらの特徴を分析するための4 つの指標,すなわち,放射線計測活動の実施主体,その計測対象となる被曝の型,その計測対象となる核種,市民計測活動の取り組み事項,を提示した.また市民計測活動を,その様々な取り組み内容を整理して8 つの類型に分け,それぞれについて先の指標を用いて,放射線防護の上でどういう意義を持つものであるかを述べた.従来行政側が一元的に担うものとみなされてきた原子力防災や放射線防護のあり方の限界を知りその打開策を探る上で,市民計測活動は大きな示唆を投げかける,歴史的な意義を持つ活動と考えることができる.

Alkaline ionized water (AKW) produced by electrolysis was given to gestational and lactational rats, and its effect on dams, growth of fetuses and offsprings were investigated. The results showed that the intake of food and water in dams increased significantly when AKW was given from the latter half of the gestation period and from the former half of the lactation period. Body weight of the offsprings in the test group, both males and females, increased significantly from the latter half of the lactation period. During the lactation period and after weaning, the offsprings in the test group showed significantly hastened appearance of abdominal hair, eruption of upper incisors, opening of eyelids and other postnatal morphological developments both in males and females, as well as earlier separation of auricle and descent of testes in males compared with the control was noted. As mentioned above, it was suggested from the observations conducted that the AKW has substantial biological effects on postnatal growth, since intake of food and water and body weight of the offsprings increased and postnatal morphological development was also accelerated.

Scapular movements and activation should be assessed in patients with shoulder disorders. In the evaluation and treatment of scapular motion, the focus must be on scapular muscle activity and scapulothoracic, sternoclavicular, and acromioclavicular joint movements. Evaluation of the relationships between the scapula and other adjacent joints such as the glenohumeral joint and trunk will also be helpful for shoulder rehabilitation. This paper presents an assessment of scapular function based on electromyographic data and a case report.

The green lacewing Plesiochrysa ramburi (Schneider, 1851) (Neuroptera: Chrysopidae) was recorded from Minami-Daito Island in the Daito Islands, representing the first report of this species in Japan. In the laboratory, larvae of P. ramburi were successfully reared by feeding on eggs of the flour moth Ephestia kuehniella (Zeller, 1879). The mean total development period at 25°C was 25.7 d for females and 23.2 d for males. I propose Semadara-nan-you-kusakagerou as the Japanese name for this lacewing species.
