本稿ではBluetoothによる受信信号強度を用いたユーザの位置推定手法を提案する.本手法は医療事故の発生要因の分析などにおいて重要となる,看護師のインタラクション情報を得るためのものである.本手法ではユーザに装着した移動局が複数の固定局から一定時間で得られる受信信号強度の平均値,最大値,最小値,中央値を特徴量として用いて位置推定を行う.本手法の有効性を評価するために,2床のベッドを配置した模擬的な病室環境での実験を行い,ベッド際のどの位置にいるかおよびそれ以外にいるかという識別については80%以上,どちらのベッドの患者に対するインタラクションかの識別においては90%以上の識別率が得られることがわかった.

In the traditional theory of consumer's behavior, circulating money is nonexistent. It is the numeraire that plays a role in it. The reason Why the l traditional theory excludes circulating money is that money has no direct utility. This is quite true under static conditions, in the strictest sense, but we can recognize direct utility in holding money, if we develop the problem under the looser static conditions in the point that they contain some assumptions as to 'time'. So, in this paper, we are engaged in modifying the traditional theory so as to be able to describe the consumer's behavior in the case where the consumer demands not only commodities but money. We begin with setting necessary assumptions and explaining what sort of satisfaction the consumer derives from holding money under those assumptions. Then we proceed to introduce money into utility function. Both C.E.V. Leser and P. A. Samuelson introduce money into utility function in the form of purchasing power over each kind of commodity. But we choose the way of introducing money into it in the form of purchasing power over the commoditiy-in-general. Our method enables us to obtain the same results more easily than they did. These results are as follows. (1) Slutsky equation should be modified so as to include two new terms besides two ordinary income and substitution terms. The two terms measure indirect income, and indirect substitution, effect. (2) Between the γth commodity and the sth one, we can not say that the substituion effect on the γth commodity resulting from a change in the sth price is the same as the substitution effect on the sth commodity resulting from a change in the γth price. This fact is due to the existence of the indirect substitution effect. (3) Consumer's income remaining unchanged, an equi-proportionate change in all price has only an income, and not substitution, effect. (4) If consumer's income changes in the same proportion as all prices, the real condition of consumer's demand remains unchanged. Accordingly, in this case, the fundamental proposition of the Quantity Theory of money holds true ; the elasticity of demand for money is unity.

At the Nara Medical University Library,we started using Twitter in June 2012 to provide timely information regarding PC use to enable efficient use of the library. Before starting Twitter, we investigated Twitter use at other university libraries and found that 75 university libraries used Twitter. We decided to tweet 3 times a day and to provide information regarding opening hours, events, and book reviews, similar to the usage at other university libraries. A year has passed since we started to use Twitter, but we have only 22 followers. Information activities should be reconsidered so that Twitter may become helpful to library users.著作権者:日本医学図書館協会日本医学図書館協会及び著作者の許諾を得て登録

本研究では,国立大学の附属図書館が Twitter をどのように利用しているのか,簡単な実態調査を行い,大学図書館の PR ツールおよびサービスツールとしての Twitter の有効性について考察した.まず,全ての国立大学の附属図書館について,Twitter のアカウントを収集し,ツイートの発言者の属性をプロフィールや図書館の公式サイトを用いて公式アカウントを同定した.次に,TwitterAPI を用いて,各アカウントのユーザ情報およびツイート 100 件を抽出し,その内容をいくつかのカテゴリに分類した.結果として,大学図書館のツイートの内容は,従来の館報や掲示による広報の範囲内に収まっており,双方向的なやりとりやリツイートによる情報拡散などの Twitter の特性を十分活用しているものではなく,主に簡易的な広報ツールとして使用されていること,また,公式アカウントがフレンドとしてフォローしているユーザの 4 割はフォロワと重複しており,必ずしも,Twitter 上での有用な情報源をフレンドとして登録しているわけではないことなど,まだ,大学図書館の Twitter 利用には課題が多いことがわかった.

Interpersonal relationships are one of the most important factors that make students resilient to stressors. In the present study, we focused on social capital as an amount of available resources derived from human relationships. We examined two aspects of social capital, namely network size and subjective social capital, to determine which of the aspects is more predictive of depressive symptoms and subjective well-being. We collected data from 1,772 undergraduate students across 38 universities. Correlational analysis showed that network size was significantly associated with depressive symptoms and subjective well-being. However, the results of hierarchical multiple regression analysis indicated that subjective social capital significantly predicted depressive symptoms and subjective well-being even after controlling for network size. These findings suggest that subjective social capital in university life is an important factor for student’s psychological adjustment and well-being.

Objective In Japan, reducing the consumption of miso soup and Japanese pickles, both traditional Japanese dishes, is recommended in order to decrease dietary salt intake. With the Westernization of dietary habits, however, these dishes are now consumed less frequently, and thus a reduction in their effect on sodium intake is suspected. This study examined cross-sectional associations between the frequency of intake of miso soup and Japanese pickles and the estimated 24-hour urine sodium excretion using data obtained from health examination surveys conducted in 2013 in Sado City, Japan. Methods The level of daily salt intake was estimated based on spot urine sodium and creatinine measurements. The frequency of intake of miso soup and Japanese pickles was determined using a self-reported questionnaire. Multiple linear regression models were used to assess associations. Results Among a total of 8,821 participants (3,956 men; age range, 19-97 years), the mean daily salt intake was 9.4 g/day. The frequency of intake of miso soup and Japanese pickles increased with age and was associated with the level of daily salt intake (p for trend <0.0001). A linear regression model analysis adjusted for age, sex, body mass index, hypertension, diabetes, hypercholesterolemia and chronic kidney disease revealed that daily salt intake was associated with the frequency of intake of miso soup (p<0.0001) and Japanese pickles (p<0.0001) in all age groups, except those ≥80 years of age. Conclusion These findings suggest that reducing the consumption of miso soup and Japanese pickles may be an effective approach for decreasing the level of dietary salt intake in the general Japanese population, although not in octogenarians or nonagenarians.
