Despite the widespread popular belief in Japan about a relationship between personality and ABO blood type, this association has not been empirically substantiated. This study provides more robust evidence that there is no relationship between blood type and personality, through a secondary analysis of large-scale survey data. Recent data (after 2000) were collected using large-scale random sampling from over 10,000 people in total from both Japan and the US. Effect sizes were calculated. Japanese datasets from 2004 (N = 2,878–2,938), and 2,005 (N = 3,618–3,692) as well as one dataset from the US in 2004 (N = 3,037–3,092) were used. In all the datasets, 65 of 68 items yielded non-significant differences between blood groups. Effect sizes (η2) were less than .003. This means that blood type explained less than 0.3% of the total variance in personality. These results show the non-relevance of blood type for personality.

盲導犬は酷使されるので寿命が短い、という話を聞くことがあるが、この話は科学的な根拠はない。今回、日本に9つある盲導犬育成施設のうち8つの施設より、盲導犬として実働していた犬の447例の死亡年齢を調査する機会を得ることができた。その結果、これらの平均寿命は12歳11カ月であり、死亡年齢が15歳を超える割合は28%だった。そのうちラブラドールレトリバーの平均は13歳3カ月、ゴールデンレトリバーでは11歳5カ月であった。死亡年代別の平均死亡年齢は、80年代で11歳、90年代で12歳3カ月、2000年代では13歳7カ月であり、いずれも家庭犬の平均寿命についての調査に比較して高いことが明らかになった。

Our recent work has shown that cannabidiol (CBD) exhibits the most potent direct inhibition of human cytochrome P450 1A1 (CYP1A1) among the CYP enzymes examined. However, the mechanism underlying this CBD inhibition remains to be clarified. Thus, to elucidate the structural requirements for the potent inhibition by CBD, the effects of CBD and its structurally related compounds on CYP1A1 activity were investigated with recombinant human CYP1A1. Olivetol, which corresponds to the pentylresorcinol moiety of CBD, inhibited the 7-ethoxyresorufin O-deethylase activity of CYP1A1; its inhibitory effect (IC50=13.8 µM) was less potent than that of CBD (IC50=0.355 µM). In contrast, d-limonene, which corresponds to the terpene moiety of CBD, only slightly inhibited CYP1A1 activity. CBD-2′-monomethyl ether (CBDM) and CBD-2′,6′-dimethyl ether inhibited CYP1A1 activity with IC50 values of 4.07 and 23.0 µM, respectively, indicating that their inhibitory effects attenuated depending on the level of methylation on the free phenolic hydroxyl groups in the pentylresorcinol moiety of CBD. Cannabidivarin inhibited CYP1A1 activity, although its inhibitory potency (IC50=1.85 µM) was lower than that of CBD. The inhibitory effects of Δ9-tetrahydrocannabinol and cannabielsoin (IC50s ≈10 µM), which contain a free phenolic hydroxyl group and are structurally constrained, were less potent than that of CBDM, which contains a free phenolic hydroxyl group and is rotatable between pentylresorcinol and terpene moieties. These results suggest that the pentylresorcinol structure in CBD may have structurally important roles in direct CYP1A1 inhibition, although the whole structure of CBD is required for overall inhibition.

The effects of the administration of molecular hydrogen-saturated drinking water (hydrogen water) on hepatic gene expression were investigated in rats. Using DNA microarrays, 548 upregulated and 695 downregulated genes were detected in the liver after 4 weeks of administration of hydrogen water. Gene Ontology analysis revealed that genes for oxidoreduction-related proteins, including hydroxymethylglutaryl CoA reductase, were significantly enriched in the upregulated genes.

We measured the frictional coefficient under banana skin on floor material. Force transducer with six degrees of freedom was set under a flat panel of linoleum. Both frictional force and vertical force were simultaneously measured during a shoe sole was pushed and rubbed by a foot motion on the panel with banana skin. Measured frictional coefficient was about 0.07. This was much lower than the value on common materials and similar one on well lubricated surfaces. By the microscopic observation, it was estimated that polysaccharide follicular gel played the dominant role in lubricating effect of banana skin after the crush and the change to homogeneous sol.

The concentration of radioactive cesium in sediments of Tokyo-bay, released by the Fukushima Dai-ichi nuclear power station accident, was measured every half year from July ’10 to February ’13 in order to analyze the trend of concentration. The samples were collected at two artificial deeper sites in dredged trenches and one natural shallower site, which were located off Makuhari in Tokyo-bay, then they were brought into a Ge detector to measure the γ-rays. According to an analysis of the upper layer of the samples, both 134Cs and 137Cs had been detected since the samples of August ’11, and they must have been released by the accident. Furthermore, from February ’12 to February ’13, the concentrations of 134Cs and 137Cs in upper layer of sediments had been higher at deeper sites than shallower site. The deeper sites look like pitfall traps for fine particles clinging to 134Cs and 137Cs, so we can call these sites "the hotspot in the sea". We also examined the depth profiles of 134Cs and 137Cs in samples taken on August ’12 and February ’13. As a result, 134Cs and 137Cs were found to have gone deeper in the sediment on February ’13 than on August ’12, and the inventory of them was also larger on February ’13. In addition, this phenomenon was observed more clearly at deeper sites than shallower site. Though 134Cs and 137Cs had not increased very much in upper layer from August ’12 to February ’13, we clarified that they had been flowing into the Tokyo-bay.

近年,「反転授業」とよばれる授業形態が注目を集めている。反転授業とは,授業と宿題の役割を「反転」させ,授業時間外にデジタル教材等により知識習得を済ませ,教室では知識確認や問題解決学習を行う授業形態のことを指す。タブレット端末やデジタル教材,インターネット環境など情報通信技術(ICT)を活用した反転授業の教育実践が初中等・高等教育で広がっている。反転授業の普及の背景には,オープン教材(OER)とICTの普及があり,わが国においても初中等教育や高等教育での導入事例がみられる。反転授業の導入によって,学習時間を増やし教室内で知識を「使う」活動を促し,学習の進度を早め学習効果を向上させることが期待される。一方で,反転授業の実施にあたっては,学校や家庭におけるICTの環境整備やオープン教材の普及,自習時間の確保や教員の力量形成が課題となる。

The cholesterol hypothesis that intake of saturated fatty acids increases blood cholesterol levels, which in turn increases the incidence of coronary heart disease (CHD), has hardly been proved. Even the most famous intervention study in Finland (Finnish Mental Hospital Study) was questionable; it must have been very difficult to diagnose CHD in heavily sedated patients without bias. However, because diabetes mellitus (DM) is one of the major risk factors of myocardial infarction, diabetologists adopted the hypothesis above to reduce CHD incidence and educated DM patients not to eat much land animals’ meat and their fat, which means high-carbohydrate diets. Unfortunately the more carbohydrate people eat, the higher blood glucose and insulin levels. In fact, if DM patients are treated with low-carbohydrate diets, hemoglobin A1c levels markedly drop. Because insulin levels are also reduced, body weight is reduced too. (Insulin is probably the most powerful agent for fattening.) The prevailing idea that low-fat is good for you does not hold true anymore. The exploding number of obese and diabetic patients in the US was the most horrible example of iatrogenic disease in the last century.

はじめに:バイスタンダーによるBLS は,実施者に相当な精神的負担がかかると想定されるが,これに関する研究自体が少なく対策も進んでいない。そこで,バイスタンダーのストレス反応を明らかにし,心のケアに関する対策を検討することを目的として調査を行った。対象と方法:2008年8月から2011年10月までの間にバイスタンダーによるBLSが実施されて社会復帰した事案のうち,バイスタンダーの連絡先を把握している事案を抽出し,当該事案の救助に携わった者を対象に面接調査を実施した。結果:多くのバイスタンダーがさまざまなストレス反応を経験していた。また,その体験を他者に話して,自分の気持ちを理解してもらいたいと考える者が多かった。結論:BLS教育において,BLS実施によるストレスとその対処法に関する教育を考慮する必要がある。さらに対策の一環として,相談を受けるシステムを整備することが有用であり,急務であると考えられる。

Comprehensive whole-body counter surveys covering over 93% of the school children between the ages of 6 and 15 in Miharu town, Fukushima Prefecture, have been conducted for three consecutive years, in 2011, 2012 and 2013. Although the results of a questionnaire indicate that approximately 60% of the children have been regularly eating local or home-grown rice, in 2012 and 2013 no child was found to exceed the 137Cs detection limit of 300 Bq/body.

マイクロブログから特定の話題に対するユーザの反応を取得する技術が研究されている.マイクロブログをソーシャルセンサとして有効活用するには,ユーザごとの特性を知る必要がある.しかし,マイクロブログでは,ユーザが属性を公開していない場合が多々あるため,ユーザごとの特性を把握できない.このことから,マイクロブログのユーザ属性を推定する研究が注目されている.しかし,既存手法では,主にマイクロブログの投稿内容にのみ着目しており,リアルタイムに発信されるマイクロブログの特性を属性推定に活かせていない.そこで,本研究では,各単位時間の投稿数に基づきユーザをクラスタリングし,投稿内容,生活習慣と投稿時間帯から職業属性を推定する手法を提案する.実証実験では,投稿内容のみを使用して推定する既存手法と,時間的特徴をも考慮する本手法について比較実験を行い,本提案手法の有用性を確認した.Research is being conducted on technology to get users' reactions to specific topics in microblogs. It is necessary to know the users' characteristics in order to effectively utilize microblogs as social sensors. However, it cannot understand the users' characteristics, because user attributes are not often to the public in microblogs. For this reason, research on estimating user attributes in microblogs has been drawing attention. However, existing methods, which merely focus on the description contents in microblogs, do not take advantage of the characteristics in microblogs that transmit in real time to estimate users' attributes. This research proposes a method for classifying the users according to number of posts per unit time and estimating the occupation attributes by description contents, lifestyle and time zone of posts. Our demonstration experiments verify usability of the proposed method by comparing the existing methods of estimating merely using description contents with the proposed method of estimating using description contents and temporal characteristics.
