EV category of the Student Formula Japan Competition will be an official event in 2013. In order to optimize the regulations of the category, we have developed an EV based on a vehicle driven by an engine for the student formula. At first, our prototype motor was applied to its traction motor and the test run was performed, and we developed an Interior Permanent Magnet Synchronous Motor (IPMSM) suitable for the formula by analyzing the test data. Furthermore, we developed a motor which achieved higher power density and correspondence to the regulation. This paper introduces the developed IPMSM.

本稿では、FUJI ROCK FESTIVAL 2015の経済的影響について考察した。現在、日本の音楽業界は大きな変化を遂げている。CDの販売量は減少しているが、音楽祭は250カ所以上で開催されている。音楽祭は盛んになり、音楽業界だけでなく地域の発展のためにも重要な位置を占めるようになった。フジロック2015の会場で、来訪者の居住地域と来訪者の購買行動について調査アンケート調査を実施し、221の有効回答を得た。経済波及効果金額は、主催者消費および、交通費、宿泊費などの来訪者消費から算出し、フジロック2015の経済波及効果は約150億円であった。これらの結果から、フジロック投資利益率は高く投資効率の良いイベントであること、来訪者消費行動に関しては初心者の訪問者よりも多額の消費傾向があることが明らかになった。また、ロックフェスティバルの構成要素を分析し、フジロックの優れた部分を明らかにした。今後、観光学の枠組みで、ロックフェスティバルを研究する必要があり、さらなる成長の為には地方自治体の関与が重要となるだろう。

In recent years, there has been a rise in the scientific threshold for establishing causality in the empirical development economics literature. In light of this development, this article discusses some specific contexts where 'endogeneity problems' arise (where systematic correlation between a right-hand-side variable and the error term in a regression equation is suspected) in microeconometric analysis using household-level data in developing countries. The article also reviews a few of the recent trends in the methodological advances in the empirical development literature that are likely to be behind the rising scientific standards in our profession. These are: the explosion in the availability of micro (household)-level data in developing countries; innovations in econometric methods (especially the search for ever 'cleverer' and 'more credible' instrumental variables, including 'natural experiments'); and innovations in data collection designs and set-ups (including randomized policy evaluations and field experiments by experimental economists). The article further argues that such recent developments in the literature could potentially provide great opportunities for agricultural economists in Japan, who have long traditions of conducting fieldwork and of being actively involved in primary data collection at the micro level. At the same time, however, we will need to pay a much closer attention to the distinction between the observation of simple statistical correlation, on the one hand, and the establishment of causality, on the other, in our empirical work.

<p>In order to increase the number of videos playback, we researched on the thumbnail images and the titles which were selected by the viewers. We built the samples and conducted the questionnaires in order to reveal the factors that make a great influence on the evaluation and be clear about the positive levels. We revealed the viewers decide the videos under the influence of the images rather than sentences and words. Also, Images factors are particularly effective for males. On the other hand, females are more affected by sentences and words than males. This research revealed the guidelines that YouTuber creates thumbnail images and titles and the elements to incorporate according to the target the males or the females. As a starting point of this research, we will be able to conduct more detailed research on thumbnail images and titles. </p>

近年,建築史や産業考古学の分野において,既存の古い構造物を価値ある資産として新たに見直す動きが見られる。そこでは主に技術史,意匠及び地域産業・生活史などの系譜の観点から価値付けが行われているが,年月を経た結果生起した「廃墟景観」としての美的特長に対する評価手法は殆ど確立していない。本研究では,主に18世紀英国の「ピクチャレスク庭園」における廃墟景観の評価論を分析し,「廃嘘」の価値付け法として,(1)アイキャッチャー,(2)自然(じねん)景観,(3)尚古象徴 及び(4)うつろい景観 の4点を指摘した。これをもとに国内の廃墟的産業構造物を例示し,価値ある景観へと昇華する可能性について検討を行った。

Mating behavior and early development of Cobitis sp. (BIWAE type D, TosaShima-dojo) were observed in the laboratory by inducing spawning of females with human chorionic gonadotropin (HCG). Subsequently, laboratory bred individuals were compared with spawned eggs and larvae obtained from the field. Mature adults, naturally spawned eggs, and larvae were collected from a river in eastern Kochi Prefecture, Shikoku Island, Japan, and a natural spawning ground adjacent to the river. Mating behavior was observed 15 times at night, and distinguished into four stages: phase 1, tracking; phase 2, approaching; phase 3, amplexus; and phase 4, spawning. Egg diameters after water absorption were 2.1–2.3 mm, the spherical, demersal eggs having a light-yellow yolk, no oil droplets, and slight viscosity. Newly hatched larvae [3.3–4.9 mm in total length (TL)] had 46 (32 + 14) myomeres, two pairs of outer gill filaments on the cheek, and melanophores on the head. Notochord flexion started at 6.0–7.2 mm TL (wild individuals at 6.0–6.3 mm TL) and was completed at 8.8 mm TL (6.6 mm TL). The formation of membranous fins and full fin-ray complements were attained in the fin order pectoral, caudal, dorsal, anal, and pelvic, and caudal, dorsal, anal, pectoral, and pelvic, respectively. Some individuals (7.0–8.0 mm TL at the flexion stage) had free neuromasts, each with a short cupula, laterally on the caudal region. In addition, following the postflexion stage, some morphological differences between artificially bred and wild individuals were observed but could not be quantified due to the small sample size.

In this paper, clarified the high school baseball culture that approve "pitching too much". One of the problems of high school baseball in Japan is "pitching too much". As a countermeasure, "pitch count limits" has not been implemented. Fans feel the appeal of "hometown" and "hard" in high school baseball. Such factors have created the ideal games for high school baseball. And fans think that "pitch count limits" loses the appeal of high school baseball. That's one of the reasons against "pitch count limits". However, it is clear that "pitching too much" has an adverse effect on the body of high school baseball players. This is a problem that should be tackled not only in high school baseball but also in the entire Japanese baseball world. High school baseball is the yearning and goal of many baseball boys and girls. And high school baseball has a great influence. The most effective reform is to change the high school baseball world. Even if the game of "pitch count limits" becomes basic, there is a possibility that a new appeal will be born there.
