Sesoko Station, Okinawa, has been the site of many significant advances in coral reproductive research and it continues to be a preferred destination for both Japanese and international researchers. Consequently, there are decades of spawning observations, which we present and explore here with the aim of making it easier to predict when species spawn at Sesoko Station. The data include over 700 spawning observations from 87 species of reef-building hermatypic corals. Almost all spawning occurred between dusk and dawn, with most spawning activity concentrated in the 2 to 4 hours after sunset. Some phylogenetic patterns were evident: most Acropora species spawn on or around the 6th full moon after December 21st (the northern hemisphere winter solstice); spawning in common species of merulinids and Porites appears to be concentrated around the 7th full moon and spawning in the fungiids around the 8th and subsequent full moons. The night of peak spawning with respect to the night of the full moon varied considerably among years in common Acropora species, but was dependent on the calendar date of the full moon in May or June. Therefore, despite an extended spawning season of over three months and considerable variation in the calendar date of spawning in many species among years, the month and night of spawning are reasonably predictable for many species enhancing the value of Sesoko Station as a site for coral reproductive research.

In this research, I investigated the design of non-circular pulley for a force/torque profile adjustment mechanism. I proposed the generalized analytical design method of the non-circular pulley applicable to the majority of structures. By using this design method, the torque acting on the non-circular pulley and the force acting on the flexible part twisted around the non-circular pulley can be converted mutually to obtain a desired torque/force profile. Also I demonstrated the design of the non-circular pulley for a spring balancer and for an arm weight compensation mechanism. Furthermore, I investigated the design limit of the non-circular pulley, and showed that too long effective radius, too long offset length, and too short radius of curvature cause the problem of impractical non-circular pulley shape. From the analysis of the occurrence condition of each case, it became clear that the derivative of the effective radius is important for avoiding too long offset length and that the effective radius and the second derivative of that are important for avoiding too short radius of curvature.

本稿は,両大戦間期の日本における<女中>イメージの変容を,第一次世界大戦後に登場した「派出婦」(=家庭などに出向いて家事手伝いに従事する臨時雇いの女性)に焦点をあてて考察するものである。第一次世界大戦後,都市部では女中不足が深刻な社会問題となりつつあった。女中が見つからない,居着かない。そんな女中払底への対応策のひとつとして打ち出されたのが「派出婦」という臨時雇いの女中のシステムである。1918年,東京・四谷に「婦人共同派出会」が設立された。派出婦は,申込者の依頼内容に応じて適任者が派遣されるしくみ。賃金は従来の女中にくらべると割高だが,必要なとき必要なだけ雇えるという利点もある。「派出婦」はその後,家庭の手不足を補う労働力として,都市部を中心に急速に広まっていった。女中になることを"奉公に上がる"といったように,日本の女中は行儀見習や家事習得という修業的な性格を有していた。これに対して派出婦は,雇用期間や勤務時間,仕事内容が前もって決められるという点で,従来の女中とは大きく異なった。そこには"修業"という側面はない。主従関係から契約関係へ。「派出婦」の登場により女中は,"職業人"としての第一歩を踏み出すことになったのである。

Prostaglandins play various roles in the brain under physiological as well as pathological conditions. This review summarizes our present knowledge about brain localization of two isoforms of cyclooxygenase, enzymes responsible for prostaglandin biosynthesis, and their possible functions. Cyclooxygenase-1 (COX-1) is con-stitutively expressed in microglia throughout the brain. Little is known about COX-1 function there. COX-1 is also abundantly expressed in the primary sensory neurons both at their cell bodies and at the central terminals in the medulla and spinal cord suggesting its involvement in sensory signal transmissions. COX-2 is constitutively expressed in telencephalic neurons in an activity-dependent manner. This neuronal expression of COX-2 was reported to be involved in the regulation of regional cerebral blood flow. On the other hand, some studies have reported that COX-2 might exert adverse actions after brain ischemia and in Alzheimer's disease. Under various infectious as well as inflammatory conditions, COX-2 is expressed in brain endothelial cells. We presented a large body of evidence that elevation of prostaglandin EZ in the brain and occurrence of fever during infection/inflammation are the consequences of this endothelial expression of COX-2. Thus, brain endothelial cells seem to transmit blood borne cytokine signals to brain by producing prostaglandin E2.

林地残材や農作物非食用部などのセルロース系バイオマスと言われる資源は再利用できるにも関わらず、廃棄されている割合が高いのが現状である。その原因はいくつかあり、収集コストが高いこと、水分含有量が高いこと、さらに難分解性有機物質を多く含むことが挙げられる。難分解性有機物質の分解方法には熱処理や化学的処理などがあるが、これらの方法は環境に対して必ずしも良いとは言えない。そこで、本研究では廃棄されるセルロース系バイオマスの有効利用を目的とし、酵母菌によるセルロース系バイオマスの分解・資化実験を行った。 実験は単一炭素源として無機塩液体培地にセルロース系バイオマス(本研究はワラとスギを使用した)を加え、長期培養した。その間、一定期間ごとに生菌数を測定した。また使用する菌は前培養した。 実験の結果、単一炭素源にワラを加えた培地では菌の生育が確認できた。また、粉末加工した方が生育に適していることがわかった。

Masuno Kosetsu was a prominent figure in Tenrikyo becoming the Shikishima Grand Church head in his late 20’s, and the president of the company publishing the periodical, Michinotomo, where he edited and also contributed an article “Architecture and Clothing in our Religion” in its 1925 May edition. This article retains a vital role in understanding the architectural intent and thoughts of the Tenrikyo at the time being one of the oldest written disquisition about the architectural aspects of the religion. Here, Masuno categorizes the features and characteristics of the Tenrikyo architecture into five periods, each a decade long, starting in 1888 when the buildings for the regional churches began. In what Masuno defined as the first period from 1888 to 1897, he defines the regional churches built during this period to be the origins of Tenrikyo church designs. Analyzing the constructed churches in those periods, the features he did not describe revealed a style. Common features consist of a wood constructed single storied ceramic tile covered hipped roof with an entrance at the front with space extending further to the back. The similar architectural features among these first generation churches suggest some discussion took place within the followers to create a standard style for the church when it did not have one to follow. Masuno considers the churches from the first period to be “dark and fragile, ” and praises the architectural development of the churches from the second period of 1898 to 1907, to “give the impression of cheerful and glorious.” As the religion grew, the need for a larger building to house the followers pressed the development of the church constructed during this period to become larger. Churches in this period although still single storied, consist of double layered roof raising the ceiling height resulting in a more airy and brighter atmosphere inside relative to the first generation of churches leading to the before mentioned impression Masuno have had. The third period 1908 to 1917 was what Masuno called it as "a stale period" with no particular development to found in his view. It was a period when the colossal construction was taking place at the Tenrikyo headquarters. The completion of the headquarter buildings provided a new reference for the regional churches to follow. Masuno describes the fourth period of 1918 to 1925 as a period when "focus was placed into the regional dioceses." In numbers constructed, the third period has built more. However, those dioceses were mostly converted buildings. As such, Masuno's assessment is correct where all of the nine constructed dioceses was explicitly designed and built for this purpose including the Nara diocese where Masuno was the head then. The fifth period is the period after the published article. Masuno predicts several new churches constructed including those rebuilding after The Great Kanto Earthquake such as Azuma, the first concrete church completed in 1931. In the same year, Tohon church also completed reconstructing their church using a steel-framed concrete system. The use of new construction material reveals their concerns towards fires. This period was also the time wood constructed churches were at their peak in scale and glamour in the likes of Koriyama, Koga, Heishin, and Shikishima; the church Masuno was the head of until his early death in 1928. These churches were similar in size as the headquarter building, and in some cases more glamorous in its ornamentation. Further analyzing the built churches of the periods Masuno defined in his article confirms his assessment and revealed the architectural origins, trends, and shifts in regional churches and dioceses of Tenrikyo at the time.
