Radionuclides were released into the environment as a consequence of the Fukushima Daiichi Nuclear Power Plant accident that occurred on 11 March 2011. Radiocesium at an abnormal concentration was detected in brown rice produced in paddy fields located in northern part of Fukushima Prefecture. We examined several hypotheses that could potentially explain the excessive radiocesium level in brown rice in some of the paddy fields, including (i) low exchangeable potassium content of the soil, (ii) low sorption sites for cesium (Cs) in the soil, and (iii) radiocesium enrichment of water that is flowing into the paddy fields from surrounding forests. The results of experiments using pots with contaminated soil indicated that the concentration of radiocesium in rice plants was decreased by applying potassium or clay minerals such as zeolite and vermiculite. The obtained results indicated that high concentrations of radiocesium in rice are potentially a result of the low exchangeable potassium and sorption sites for Cs in the soils. Application of potassium fertilizer and clay minerals should provide an effective countermeasure for reducing radiocesium uptake by plants. Radiocesium-enriched water produced by leaching contaminated leaf litter was used to irrigate rice plants in the cultivation experiments. The results indicated that the radiocesium concentrations in rice plants increased when the radiocesium-enriched water was applied to the potted rice plants. This indicated the possibility that the radiocesium levels in brown rice will increase if the nuclide is transported with water into the rice paddy fields from surrounding forests.

京都市の伏見区、かつての伏見城城下の西部にあたる場所で江戸時代の廃寺の墓地(伏見城跡遺跡)が調査でされ、約630人分におよぶ古人骨資料(伏見人骨資料)が発掘された。この資料を骨人類学や骨考古学的の方法で分析して、江戸時代人京都町民の顔立ちや体形などの身体特徴、平均寿命や人口曲線などに関する人口学的特徴、歯疾患や骨梅毒疾患などの罹患率を明らかにするとともに、主要なタンパク質摂取源を推定する食性分析、人骨の鉛濃度分析などを実施した。成人の平均身長は男性が158cmで女性が144cmほどと短躯であったこと、丸顔の人が多かったこと、出生児の平均余命は男性が40歳弱で女性が30歳弱ほどと短命であったこと、虫歯と梅毒の罹患が著しく高率であったこと、淡水産や海産の魚介類をタンパク質源として利用していたことなど、すくなからずの特記すべき研究成果を達成できた。

The SHINKAGE-YAGYU-RYU (one of the Kendo Schools) was founded by Muneyoshi YAGYU who had been influenced by Hidetsuna KAMIIZUMI (SHINKAGE-RYU). In the early 17th century, this school was succeeded by Toshitoshi YAGYU who was the Muneyosi's grandson. He had been to the Higo (Kumamoto district) and had met Kiyomasa KATO in 1603. He had been able to know the national situation, so he founded the original style of SHINKAGE-YAGU-RYU when he went back to the Yagyu (Nara district) again. Furthermore, his son Toshikane YAGYU, who was influenced by his father started to change the KATA (form)in this school.The porpose of this study is to clarify the change of KATA from Muneyoshi to Toshitoshi, Toshikane. The findings are as follows.1. As Toshitoshi denied his father's KATA, he founded the new style called “TSUTTATTAR U-MI-KAMAE”which was a form of changing one's weight from legs to waist.2. Although Muneyoshi didn't write down the mental things in letters, Toshitoshi started to write down these things. (for example, BOUSHIN, KI, the sound of wind and water)3. Toshikane changed the system of learning the KATA in this school, and after that he established the phased method of teaching.4. He contrived the “GASSHI-UCHI” which didn't exist before. Although this technique was an actual fighting, it was rater considered a technique to practice mental elements.

子どもが「おもしろい」と感じる絵本を推薦するシステム構築の基礎的準備として,絵本の主題が子どもの反応とどのような関連を持つのか検討を行った.そのために,34組の親子による絵本の読み聞かせを記録し,ページ毎の絵本の主題と子どもの反応の関連を分析した.その結果,「見る」,「座る」,「考える」,「失敗する」,「話す」,「住居」,「楽しむ」,「他者を認識する」の8主題について子どもが好きな絵本で見せる反応と関連があることが分かった.さらに,個々の反応と主題の関連を分析することで子どもの反応を扱う際の問題点を明らかにした.

It is shown by carrying out numerical calculations based on the stochastic Verhulst equation that the average value of the pupulation gives only a single peak, which contradicts with the previous result with several peaks.

The purpose of this study is to indicate career patterns and career orientations of youth players in J-league clubs. Questionnaires were distributed to 122 players over different four J-league clubs resulting in 100 (81.9%) usable data. In order to identify the usable participants, we used longitudinal method for the players' career patterns and comparison analysis of player's motives and career orientations for J-league youth clubs. The main results of our study were as follows: ●In the J-league youth clubs, 55.6% of players came from J-league junior youth clubs, whereas 31.3% of players came from other clubs, and 13.1% of players came from junior high school team. ●The comparison analysis of motives for J-league youth clubs showed no significant findings among three groups from junior high school, except for those that "used be a fan of the team." ●84.0% of the players of J-league youth clubs would like to play for a top team in the J-league in near the future and approximately 70% of players want to find a job related to soccer (e.g., coach, team staff, and so on).
