(目的) 精巣捻転症は,診断治療が遅れると精巣を喪失するため,臨床的社会的に重要な救急疾患である.近年,精巣捻転と外気温との関連が指摘されているが,その詳細は明らかでない.今回,急性陰囊症手術症例を後方視的に集計し,精巣捻転発症と外気温との関係について検討を行った. (対象と方法) 対象は2004年10月から2014年10月までに精巣捻転症が否定できず,手術が行われた急性陰囊症105例.患者病歴より年齢・居住地域・発症日時・手術検査所見等の情報を収集した.発症日の外気温は,気象庁ホームページより居住地域に最も近い気象台のデータを用いた.χ2乗検定,ウィルコクソンの順位和検定,ロジスティック回帰分析で解析を行った. (結果) 年齢中央値13(1~43)歳,患側は右側46例,左側58例,両側1例であった.術中所見で67例が精巣捻転症,38例が非精巣捻転症と診断された.発症日平均外気温は捻転群で中央値10.8℃(1.8~29.4℃),非捻転群で19.4℃(1.9~29.1℃)あり,捻転群で有意に低かった(p=0.006).精巣捻転症の割合は,発症日平均外気温が15℃未満の場合45/56(80%)で同15℃以上での22/49(45%)と比べ有意に高頻度であった(p<0.001).また平均外気温15℃以上でも,最高最低気温の差(日内気温差)が10℃以上の場合に13/21(62%)で,同10℃未満の9/28(32%)と比べ精巣捻転症が高頻度であった(p=0.037).多変量解析の結果,年齢・血清CRP値・発症日外気温が急性陰囊症手術症例中から精巣捻転症を予測する有意な因子であった. (結論) 低外気温または日内気温差が大きい日の急性陰囊症は,精巣捻転症の可能性が高く,注意すべきである.

In recent years, there has been an increasing demand for position sensorless control in PMSM drives, and various methods have been studied. Switching noise is a problem in the low-speed sensorless control method that uses the current slope during PWM. Furthermore, another problem is that the inductance does not appear in a sinusoidal distribution owing to magnetic saturation.In this paper, we improve the sensorless control method that estimates the position from the current slope during PWM, which is greatly affected by switching. Additionally, we build a multi-layer neural network (NN) that directly estimates the position signals by learning a large amount of current data, and verify the driving results in the low-speed range when the learned NN is incorporated into real-time control.

本論文では,大型擦弦楽器において特定の音高を演奏した際に生じるウルフトーンを技術的に抑圧するための指針を示すため,擦弦条件(弓の速度や圧力の組み合わせ)と発生範囲の関係を数値計算により求めることを目的とする。まず楽器の等価モデルを用いてウルフトーンを再現した後,弓の速度や圧力を網羅的に変化させウルフトーン発生状態マップを作成し,これと実験結果を比較することでモデルの妥当性を検証した。その結果,弓の速度変化によるウルフトーンの周期変化の傾向や,圧力を維持したまま弓の速度を減速することで抑圧されるといった傾向が実験結果と定性的に一致し,本モデルの妥当性が示された。

This paper discusses female allegorical statues, that is, Motherland and the Lamenting Mother, as Soviet monuments and memorials about the German-Soviet War of the Second World War. In general, we do not meet female citizens in public monuments because modern nations purge women from public spaces to private areas, that is, family spaces. Instead of individual women, they use images of allegorical women, for example, the Archaic goddess Nike/Victoria as a symbol of an imagined community and Marianne in the French Republic.In Soviet war monumental/memorial space, we meet such a symbolic gender structure: Red Army soldiers and allegorical females. In this case, we consider the Archaic goddess featured in Motherland and the Lamenting Mother statue. Since the collapse of the Soviet Union, in the process of restructuring war memorial spaces, newborn nations have removed male statues, for example, Lenin, revolutionists, politicians, generals, academicians, artists, and Red Army soldiers, which commemorate great Soviet hegemony. In contrast, female allegory stays in public spaces even today because female unindividual statues are an empty medium that can introject any concept.It was found from the result of fieldwork in the former Soviet Union that Motherland, which has occupied a position as national symbol in the Russian Federation, has lost power to unite nation and people. In fact, the Motherland statue had not been built in Estonia, Lithuania, Azerbaijan, or Central Asia. Regarding Latvia, Moldova, Belarus, and Georgia, we meet small-size variants. On the other hand, Lamenting Mother statues, who mourn for the war dead, have been raised in the whole country, even today. Local communities find space to share the pain of loss of relations and friends, homes, property, and life, in memorials in the shape of the Lamenting Mother, who is similar to the Holy Mother.We are here concerned with the implications of social and cultural context of these two female allegories. In the first chapter, we focus on the period of Khrushchev. Stalin had oppressed all war memory and, after his death, people began to narrate personal experiences about war and build memorials for the dead in burial places. We cannot find a clear distinction in early female allegory statues. The 20th anniversary of the Victory, that is, the year 1965, brought a fundamental change in war memorial-commemoration spaces. In those days, Nike-type statues were raised as national symbols to unite the nation and people, such as The Motherland Calls at the top of Mamai Hill to commemorate the Battle of Stalingrad. In the second and third chapters, we illustrate distribution, location, size, shape of Motherland and Lamenting Mother statues in detail. Next, in the fourth chapter, we classify Lamenting Mother statues according to type of icons of the Holy Mother: Eleusa, Pieta, Our Lady of Sorrows, and Orans. We consider that the cult of the “Lamenting Mother” is based on the faith of the Holy Mother. Next, we surmise that early Christianity had united the faith of the Holy Mother with the cult of local great mothers in the course of Christian religion in Europe. Similarly, Islam assimilated local great mothers in Central Asia. It is possible that Soviet people, including Muslims, had a basis for accepting the Soviet secularized Holy Mother. And, finally, we examine threat factors inherent in the Lamenting Mother-type statue.

Keloids are chronic inflammatory fibrous tumors that cause excessive production of such extracellular macromolecules as collagen, due to the overexpression of various growth factors and cytokines. The etiology of keloids is unknown. They cause pain and itching, which together with the red mass leads to physical and mental stress in patients. No definitive treatment for keloids has been established, although various treatment methods have been reported, and the current consensus is that the recurrence of keloids cannot be completely suppressed. Elucidation is awaited of the pathologic mechanism of keloid development and identification of signal transduction pathways that will help establish a molecular targeted therapy for keloids.

National Aerospace Laboratory has been developing the STOL research aircraft named “ASKA” which underwent its maiden flight on October 28th, 1985. This project was started for the purpose of establishing STOL technology in Japan. In order to improve the stability and control of the ASKA in the low air speed region, the ASKA has a triplex digital stability and control augmentation system (SCAS) in which new technologies are introduced. This paper describes the outline of design objectives, functions, a series of development tests and results of the SCAS which include triplex digital computer systems, a triplex force summing electro hydraulic series servo actuator, a head-up display and a low airspeed sensor. Most of the development tests were devoted to verifying the system hardware and software through control system functional mockup tests, and flight simulator tests connecting with the digital computer systems. And finally the overall functions of the SCAS were tested in actual flight. The problems encountered during these tests are also presented.

A collection of the Hepaticae and Anthocerotae made by T. Makino was studied and 85 species were here reported. It included many specimens collected in the central area of Tokyo about 100 years ago; they are of great value in studying the drastic change of natural environment in the metropolis during this century. In the collection were found such epiphytic species as Frullania osumiensis, F. parvistipula, Macvicaria ulophylla, etc., and such terrestrial species as Chiloscyphus polyanthos, Jungermannia atrovirens, Lejeunea japonica, Mannia fragrans, Phaeoceros parvulus, etc.; they have not been found in the area in many decades. A biographical sketch of Tomitaro Makino (1862-1957) and Kiichi Miyake (1876-1964)was also given to show their activities in the early time of Japanese bryology.

This is a critical essay on Bill O’Reilly’s American best-seller, Killing the Rising Sun: How America Vanquished World War II Japan (2016), which, soon introduced through the Internet, shocked some Japanese intellectuals. Considering the pitiless, ill-intentioned content for the Japanese, the book will never be translated into Japanese and probably remain unknown to ordinary people in Japan, many of whom like the United States. The writer of this essay, a Japanese scholar of comparative literature, analyzes how the atomic bombings are justified in Killing the Rising Sun, and criticizes the book using relevant materials, like the TV drama The Pacific produced by Steven Spielberg and Tom Hunks, which describes how innocent patriots like Eugene Sledge were to become coldblooded killers through the bloody battles against Japanese counterparts in Pacific islands like Peleliu; such theme is so universal that the series still has fans in Japan. The Japanese translation of Tears in the Darkness: the Story of the Bataan Death March and Its Aftermath, a wonderful book by Michael & Elizabeth Norman, also has succeeded in moving the Japanese readers with the two different perspectives of America and Japan, and the authors’ sympathetic attitudes toward the ex-enemies. For example, the so-called beasts did not use Japanese swords so often as the fans of Killing the Rising Sun might imagine: in Mr. and Mrs. Norman’s book, a Japanese officer used his precious weapon just after he knew that the captive had stolen some money from one of his dead soldiers. Bill O’Reilly, on the contrary, only tells stories about good Americans fighting bad Japanese. Since he uses the present tense showing how America comes to drop the atomic bombs, it is understandable that his hatred is keen enough to appreciate Truman’s decision to kill hundreds of thousands of Japanese civilians even though the president seems to have regretted to know that innocent women and children also died the most violent deaths ever known in human history. As Yuko Tojo, granddaughter of war-time prime minister Hideki Tojo, was welcomed by American veterans, offering flowers at the memorial service for the US marines in Peleliu in 1999, Japan and the United States are now close friends, having forgiven each other. Japan’s war crimes were severely punished at the International Military Tribunal for the Far East and other trials in foreign countries such as China, the Philippines, and Russia. Nearly one thousand Japanese were executed, some of whom had been wrongly accused and spent their agonizing last days. General Iwane Matsui, one of the unfortunate, had respected China and had ordered all his soldiers to maintain military discipline, but was hanged for the now-called Rape of Nanking. Having built Koua-Kannon (a statue of the Goddess of Mercy for the Rising Asia) in Atami, Shizuoka Prefecture, Japan, the retired general had prayed every day for the souls of both the dead Japanese and Chinese soldiers. The Kannon statue still exists tenderly preserved by an elderly nun and her supporters. The world will admit that the Japanese are now peace-loving people. The atomic attacks are justified in Killing the Rising Sun in four ways: 1) by insisting that the Japanese were beasts; Tojo was a Hitler; Emperor Hirohito was incompetent, 2) by regarding the bombings as rightful revenge to Pearl Harbor, 3) by stressing that the two bombs saved "hundreds of thousands" of American soldiers, and 4) by mentioning that Bill O’Reilly was born thanks to the atomic bombs which saved the life of his future father who was about to take part in MacArthur’s land invasion of Japan. In answer to these, 1) The Japanese soldiers were not beasts, let alone women and children. Their violent acts were due to the nature of war itself. View PDF for the rest of the abstract.
