Xenopus laevis, a frog commercially traded as a laboratory and pet animal, was first recorded in the wild at four localities in the Kanto plain, central Japan. Frogs found in the Tonegawa River might be a feral population established in the past decade because several X. laevis have been collected intermittently since the late 1990's. It is uncertain, however, whether Xenopus found at three other localities (Hasuike Pond in Fujisawa City, Inbanuma Pond in Shisui Town, and A ditch in Nagara Town) have established feral populations because there are few or no subsequent capture records since the first record at each locality.

Reporting of reliability coefficients is an important procedure in articles describing the development of new psychological scales. However, it appears that Japanese psychology researchers have not yet arrived at a consensus regarding what constitutes a desirable magnitude for a reliability coefficient. In this study, I conducted a meta-analysis summarizing 65 test-retest correlations from 58 studies published in the Japanese Journal of Psychology, which is a highly-ranked peer-reviewed psychological journal in Japan. The results of a meta-analysis, which involved the use of a random effect model, showed that the desirable mean test-retest correlation was ρ =.76 (95% CI =.70–.81). There was no significant relationship between the test-retest correlations and coefficients alpha. The number of items of the scale correlated positively with the test-retest correlation coefficients. Researchers tended to mention problems regarding test-retest coefficients only when they were less than r =.50. The desirable usage of reliability coefficients was also discussed.

コンパクトな都市の方が1人当たり歳出は低いが,コンパクトな都市へ再構築することは簡単ではない。しかし,何もせずに手をこまねいていたらならば,今後予想される人口減少によって,今以上にコンパクトでない都市へと変貌(非コンパクト化)してしまう可能性がある。本稿では「基準化された標準距離」を都市のコンパクト化の度合いを示す指標として用いて,人口減少に伴って進む非コンパクト化が財政に与える影響をシミュレーションした。その結果,非コンパクト化による歳出増加額は,全体で2030年度は2867億円,2045年度は5549億円となった。特に,人口規模が小さい市町村において,非コンパクト化の影響が大きく出ることも明らかとなった。さらに,「基準化された標準距離」を現在よりも10%および20%縮小するという政策を実施すると,最大で10%の場合に4568億円,20%の場合に8640億円の削減効果が示された。

Castings in plate form of commercially pure titanium KS50 and three titanium alloys, Ti-5Al-2.5Sn, Ti-6Al-4V, Ti-15Mo-5Zr, were prepared by using graphite molds and an arc skull furnace which was of tilting pour type with consumable electrodes, as previously reported. Mechanical and corrosion resistant properties of these castings were studied and compared with those of forged materials. In the case of KS50 and the α alloy, Ti-5Al-2.5Sn, there was no significant difference ofmechanical properties between the as-cast and the annealed castings. However, the strength of the α + β alloy, Ti-6Al-4V, in which phase stabilization occured during annealing, was increased by annealing. The hardening and the reduction of ductility due to ω phase formation in the Ti-15Mo-5Zr alloy castings were suppressed by annealing. There was no large difference of mechanical properties between castings and forgings of KS50. However, the Ti-5Al-2.5Sn alloy castings showed significant decrease of strength, compared to the forged materials, while the Ti-6Al-4V alloy castings showed slight decrease of strength and large reduction of ductility. The inferior properties of the castings seemed to be due to the large grain size. The presence of pin holes in castings of 0.5mm in diameter had a negligibly small effect on the tensile and smooth rupture properties. Annealing of the KS50 and the Ti-15Mo-5Zr alloy castings showed a small effect on the corrosion resistant properties which were, thus, comparable to those of the forged materials. α precipitates due to dendritic micro-segregation were observed in the Ti-15Mo-5Zr alloy castings and were not eliminated by the annealing treatment.

The purpose of this study was to examine the similarity in chronic regulatory focus (promotion/prevention) among mothers and daughters of young, middle, and older ages. A survey was conducted using the shortened 10- item form of the Japanese version of the promotion/prevention focus scale, and 77 sets of grandmothers (77.79 ± 5.61 years), their daughters (49.26 ± 4.12 years), and their granddaughters (20.17 ± 3.89 years) were studied as a part of the analysis. I compared scores on the promotion/prevention focus scale between grandmothers and their daughters (older age group) and granddaughters and their mothers (younger age group). The results show that the strength of a daughters’ promotion and prevention focus was similar to that of their mothers’ in the younger age group. On the other hand, only the strength of daughters’ prevention focus was similar to that of their mothers’ in the older age group. The results of this study suggest that daughters may be similar to their mothers, as they age, in their strategies to adapt to changes that focus on loss and risk.

Urine should be a most valuable routine sample in clinical laboratory. Laboratory data in urine are, however, more or less influenced by many known or unknown, pre-renal, renal and post-renal factors, thus giving the measured value complex and equivocal. In relevance with physicochemical properties and structure of individual proteins, the present author reviewed the factors and their effects on laboratory data in the framework of quality assurance system. Taking properties of individual proteins into considerations we must need to strengthen their clinical significance continuously by investigating and eliminating what are affected by the participating factors.

東日本大震災に引き続いて発生した福島第一原子力発電所事故により,主に福島県内に放射性物質が飛散し,福島県民において小児甲状腺がんが心配されたため,福島県民健康調査の詳細調査として甲状腺検査が震災の約半年後に開始された。これまで実施された先行検査および本格検査(検査1回目)の結果において,悪性あるいは悪性疑いと診断された対象者の二次検査受診時の年齢は,ほとんどが10歳以上であり,診断例数は年齢と比例して増える傾向があったことや,推定甲状腺吸収線量と悪性あるいは悪性疑い結節の発見率との間に線量依存性が認められなかったことなどから,発見された甲状腺がんと放射線被ばくの間の関連は考えにくいと評価されている。また,甲状腺癌には生涯にわたって死亡や症状などの問題をきたさない可能性が高い甲状腺癌がみられることが知られているため,甲状腺検査においては,関係学会のガイドラインに従い,二次検査の実施基準と穿刺吸引細胞診の実施基準を設け,検査を実施している。本稿においては,これまでの甲状腺検査の方法と進捗状況について報告するとともに,これまで得られた結果について概説する。

The 'Communicative Approach', originated in Europe in the 1960's, encompasses a variety of methods that apply new concepts in the field of foreign language teaching. This term literally refers to a combination of language teaching approaches that aim to improve communicative language skills, discourse skills, and social linguistic skills. In Japan, for the last 40 years, the audio-lingual method, which emphasizes drilling and memorization, has been the main focus of elementary Japanese language teaching. But this authorized teaching method has come under criticism in recent years, and this has caused a certain amount of consternation amongst Japanese teachers accustomed to the previously established teaching system. This paper will propose a new style of teaching which combines the best of audio-lingual method and the communicative approach.

中国黄土高原の環境史をめぐる研究動向を分野横断的に整理し,今後の研究の課題と方向性を示した.黄土高原の環境史研究は,「人為的植生破壊が土壌侵食を加速させ,黄河の洪水頻度を高めた」という歴史地理学の主張の一方,地質学は「森林は山地のみにあって黄土高原の大半の原植生は草原であり,植生減少を駆動したのは寒冷乾燥化である」と反論するなど,分野ごとに切り分けられてきた.しかし,両者の研究対象のスケールが異なったため,黄土高原の土壌侵食に及ぼす人間活動と気候変動それぞれの影響はいまだ不明瞭である.この課題に対して本稿では,時間・空間スケールの指標として「地形」に着目する.地形が変化しているにもかかわらず,これまで多くの研究者は,現在の地形区分を過去に適用していた.人間活動と気候変動とが土壌侵食に与えた影響を解明するためには,地形の発達を踏まえて黄土高原の環境変遷を明らかにすることが必要である.

This paper examined the effect of the belt and road initiative by the Chinese government on the Central and Eastern European countries (CEEs), with focusing on the motorway project in Montenegro, named Bar-Boljare highway.For the Montenegro government, this project had been the national desire since its independence. But the European Union (EU) had not accept to assist Montenegrin highway project because of economic inefficiency and so on. In such a circumstance, the Chinese government supported the Bar-Boljare highway project by supplying loans 687 million euros to enhance its influence on the CEEs. As a result, the government of Montenegro increased its debt by 10 percent point of GDP. Western society criticized the China government because its loans made Montenegro to public debt crisis. However, this view was only one-side based on western values.The analysis in this paper concluded that the conflict between EU and China on Montenegrin highway project worked as one of the external pressures on forcing EU rethink its enlargement strategy to the Western Balkans, the peripheral countries in CEEs. Joining other pressures, for example, geopolitical confliction with Turkey and Russia and so on, EU changed its enlargement stance to Western Balkans from negative to positive. EU has started a summit with Western Balkans to communicate deeply. But EU has not yet provided the financial support for economic development.These facts asked EU whether its expansion strategy is correct or not. Its passive stance to Western Balkans allowed expansion of the Chinese political and economic power to there. If EU regards Western Balkans strategically important regions, EU must change its passive support stance to more vigorous one. As the same time, EU needs improve its lack of determination.
