グローバル化が進行する現代において、指紋、静脈、虹彩、声紋、顔といった身体的特徴を利用して個人を識別する生体認証技術が世界的に普及している。そもそも19世紀末に植民地統治と国民国家形成ひいては帝国形成のもとで誕生し、使用されてきた生体認証技術が、今日ふたたび注目されている理由とは何か。そこで本研究では、近代から現代に至る身体管理の変容と特徴を、生体認証技術の歴史を軸に描き出した。

災害研究・災害科学の領域では、「災害を語る」ことの意味や効果について、真に検証されていなかった。本稿では、これまで筆者が「災害対応経験を語ること」の意味や効果について実証的に検証してきた内容を紹介する。1つめは、宮城県庁職員における東日本大震災発生以前の災害対応経験の継承事例をもとに、語り合いの効果を定性的に検証した事例を示す。2つめは、震災語り部の語りを受けた聞き手におよぼす生理反応・心理反応・記憶量の変化を実証した実験研究の事例を示す。最後に、これらのエビデンスにもとづいて実践されている東日本大震災発生後の宮城県庁職員における継承の実装事例を紹介する。

This study is to find the local damage and failure of concrete plate due to the contact and close-in explosion by C4 explosive. First, to examine the blast effects by C4 explosive, basic explosion tests were done. Then, the relation between the maximum overpressure and distance from an explosive source is formulated. Next, to examine the local damage and failure of concrete plate due to the contact and close-in explosion by C4 explosive, the small scale explosion tests were carried out. In tests, the concrete plates (50cm x 50cm square) were employed. And, to know the material model and parameter to be used for the hydro code AUTODYN, some of test cases were numerically simulated.

最近の映画はシーンの入れ替わりが早くて字幕を読むのが大変である。観賞中に映像ばかりに集中していると字幕を読み逃してしまう。反対に字幕ばかりに集中していると映像を見逃してしまう事がある。そこで、字幕のレイアウトを4種類用意し、それぞれ可読性が変化し向上するか調査した。実験ではアイマークレコーダーを使用して行った。実験の結果一番読みやすいサンプルはCであり、字幕との相性はサンプルAが一番を言う結果になった。今回の実験では対象のシーンに合った字幕とは一概に言えない。今後サンプル数を増やし正確な結果を追求する。

It is widely acknowledged that high viscosity water-soluble dietary fibers such as pectin and guar gum affect a lowering of blood glucose levels and a reducing of insulin secretion following a sugar load. However, as dietary fibers vary in origin and in chemical properties, their physiological functions differ as well. In this study the effects of Indigestible Dextrin (PF-C), a low viscosity, water-soluble dietary fiber obtained through acid and heat-treatment of potato starch, on various aspects of sugar tolerance were examined.First, the influence of PF-C on sucrose hydrolysis was examined in rat intestinal mucosa cell homogenate confirming that PF-C did not inhibit sucrase activity. Then, in order to investigate the influence of PF-C on sugar digestion-absorption, an experiment was performed by using the everted intestinal sac of the rat in vitro. PF-C did not have an effect on glucose-transport into the serosal medium, whereas PF-C did inhibit the transport of hydrolyzed-glucose from sucrose, with no change in the hydrolysis of sucrose.Recently, Crane et al. reported that there is a specific route for hydrolyzed glucose from sucrose in glucose-absorption on the enteric surface (disaccharidase related transport system). The possibility exists that PF-C specifically affects this pathway. Further, total glucagon released into the serosal medium stimulated by both glucose and sucrose were reduced by PF-C.On the basis of these results, an oral sugar tolerance test was conducted in both rats and healthy human subjects. In male Sprague-Dawley rats (8 weeks old, 250-280g) concurrent administration of PF-C (0.6g/kg body weight) reduced an increase in plasma insulin levels with no change in glucose levels following a glucose (1.5g/kg body weight) load. Further noted were reductions in increases in both plasma glucose and insulin levels following a sucrose (1.5g/kg body weight) plus PF-C (0.6g/kg body weight) load to that of the sucrose (1.5g/kg body weight) single load. These findings reflect the above mentioned in vitro results. Moreover, in healthy male subjects the increase in both plasma insulin and glucagon-like immunoreactivity (Gut GLI) levels following a Trelan-G75 load were significantly reduced by concurrent administration of PF-C.From these observations it would appear that the effectiveness of reducing insulin secretion by PF-C results due to the decrease in sugar absorption by inhibiting the disaccharidase-related transport system. As glucagon-like peptide 1 (GLP-1), [an incretin in the enteroinsular axis] secreted with Gut GLI from intestinal L cells, is known to enhance insulin secretion following a sugar load, the resulting effectiveness by PF-C to reduce insulin secretion is thought to be attributed to the action on this enteroinsular axis mechanism.

Since World War II Japanese villages have been transformed dramatically. With the shortage of agricultural labor in Japan, villages today have been hurt by the problems of an aging labor force. The Japanese government tried to reorganize the agricultural structure after World War II. But many farmers who hold small cultivated plots have maintained their operations. Under such conditions, it is important to research agricultural change from the point of view of how cultivation is maintained. Nevertheless, at this point in time, few investigations have provided detailed case studies. In particular, it is rare to find a case reported from the view of agricultural production from the agricultural labor side. This paper aims to clarify the mechanism of agricultural continuance by means of a detailed case study in Takamiya-cho, a village in Hiroshima Prefecture. The methodology is as follows. In the previous studies on the shortage of supply of agricultural labor, in addition to many discussions of part-time farmer, two main labor supply source systems have been discussed. One of them is the “weekend farmer” who lives outside his home village and returns to the village to help with his family's farm in the busy farming seasons or on weekends. The other is the trust system of agricultural lands and works. The former is a phenomenon that occurs in individual farm households, but the latter is a system that occurs in groups of farm households. This study investigates how these two systems function in a village with an aged population. Three types of farmer can be classified according to the labor supply situation. The first type is the successor who lives with his aged parents and works in the non-agricultural sector. Where this type of farm household is prevalent, cultivation can be continued because the agricultural labor force will be reproduced even with part-time farming. In such a situation only rice will be cultivated, by a small labor force using agricultural machinery. In the second type, the agricultural labor force is supplied by “weekend farmers.” In this type cultivation is maintained by the labor supply system in each farm household itself. The labor supply of “weekend farmers” is available for mechanized agriculture, but serious problems will occurred in the near future, because there is little probability of reproducing the agricultural labor force. In the third type, the labor force is supplied by an agricultural trust. This type is a labor supply system that works in groups of farm households. This type of labor supply is available not merely in villages with an aged population but also in villages where part-time farming is predominant.
