Torquigener albomaculosus has been found at depths of 10–30 m on the southern coast of Amami-Oshima Island, Kogoshima Prefecture, and at 100 m off Hamahika-jima Island, Okinawa Prefecture. However, there have been no reports on the morphology and pigmentation of the larvae and juveniles. Eggs of To. albomaculosus were collected from the southern coast of Kakeroma-jima Island, Kagoshima Prefecture, at a depth of 32 m, and development of eggs, larvae, and juveniles were observed in captivity. Comparisons were made with previous reports on the development of pufferfish species inhabiting Japan and adjacent seas. Eggs were 0.96 ± 0.02 mm (n = 20) in size, spherical in shape, colorless, transparent, demersal, and adhesive. Immediately after hatching, larvae were 2.43 ± 0.08 mm (n = 11) in total length and the number of myomeres was 8 + 11 = 19. Dendritic melanophores were present on the dorsal surfaces of the head and body, dorsal and ventral sides of the abdominal cavity, but were absent from the caudal region. The mouth and anus had already opened but the yolk still remained. The yolk was absorbed within 2 days of hatching. At 19 days after hatching, ossification of teeth began in the upper and lower jaws. Simple small spinules appeared on the gill covers and abdomen. They were pointed at the distal end and not divided. Black melanophores were distributed from the snout to the region between dorsal- and anal-fin bases, absent from the caudal region. The larvae became juveniles 36 days after hatching. At 61 days after hatching, the sides and dorsal surface of the body were silver, the ventral surface was yellow, and the area covered by small spinules extended posteriorly beyond the dorsal and anal fins. The larvae and juveniles of To. albomaculosus can be distinguished from those of other pufferfishes inhabiting the waters around Japan by the absence of black melanophores on the caudal region, the distribution and development process of small spinules, and body color.

紀伊山地中央部の秩父帯は大峯-大台スラストで四万十帯の構造的上位にある.大峯-大台スラストは弧状および半円形断層で変位している.秩父帯は東西幅30km以上の弧状断層および直径15km以上の半円形断層の内側にみられる.両断層は同心円状の形状を示す.安山岩と安山岩-石英斑岩複合岩脈からなる弧状岩脈群が弧状断層の内側に貫入している.半円形断層の外側に並行して火砕岩岩脈群が貫入する.中生界(秩父・四万十帯)は両断層と火砕岩岩脈群の内側が数百m陥没する.これを大峯・大台コールドロンと命名する.前者は弧状断層で囲まれる.後者は半円形断層と火砕岩岩脈群で囲まれている.これらの特徴はコールドロンが連続して形成された二重のコールドロンであることを示す.コールドロンにともなわれる岩脈群の放射年代はこれらが中期中新世に形成されたことを示す.大峯・大台コールドロンの形成機構は大量の火砕岩の噴出によるピストンシリンダータイプの陥没と考えられ,特に大台コールドロンはトラップドアタイプの陥没と考えられる.紀伊山地中央部の秩父帯はこれらのコールドロンの内側に残存する中生界である.紀伊山地の隆起と侵食により,これらのコールドロンから噴出したカルデラ充填火砕岩層はコールドロンの周囲には残っておらず,カルデラ床を構成していた中生界が露出するにいたった.

三都涼之図

京都の祇園祭の夜景を描いた「皇都祇園祭禮四條河原之涼」の図は、貞秀の傑作のひとつと言われている。無数の灯りの下、鴨の河原に涼み床を並べ、様々な人々が茶屋や見世物で夏の宵を遊び楽しんでいる。四条大橋の上では祇園の社から御旅所に向かう神輿と、群衆がひしめく。手前には「三條ノ小鍛冶作長刀」と由緒標記を画中に付した疫病邪鬼をはらう長刀鉾や、新月の鉾頭の月鉾が聳えている。背景には比叡山や、大文字の如意ヶ岳をはじめとする東山の連峰が描かれ、南は五条、北は遙か大原の里までパノラマのごとく眼下に広がる。寺院や地名も記されており、都の名所ガイドも兼ねる華やかで賑やかな錦絵である。早期の摺りで、構図、色調ともに優れ、赤い提灯と川面の青、緑の山膚が映え合って美しい。各図の下方に「五雲亭貞秀画」の落款と、「小泉彫兼」あるいは「彫兼」の彫師銘がある。「藤慶」は版元藤岡屋慶次郎の商標印、「未弐改」は安政六年己未歳三月の改印(検印)である。

Methane (CH4) is an important greenhouse gas and plays a significant role in tropospheric and stratospheric chemistry. Despite the relevance of methane (CH4) in human-induced climate change and air pollution chemistry, there is no scientific consensus on the causes of changes in its growth rates and variability over the past three decades. We use a well-validated chemistry-transport model for simulating CH4 concentration and estimation of regional CH4 emissions by inverse modelling for the period of 1988-2016. The control simulations are performed using a seasonally varying hydroxyl (OH) concentrations and assumed no interannual variability. Using inverse modelling of atmospheric observations, emission inventories, a wetland model, and a δ13C-CH4 box model, we show that reductions in emissions from Europe and Russia since 1988, particularly from oil-gas exploitation and enteric fermentation, led to decreased CH4 growth rates in the 1990s. This period was followed by a quasi-stationary state of CH4 in the atmosphere during the early 2000s. CH4 resumed growth from 2007, which we attribute to increases in emissions from coal mining mainly in China and intensification of ruminant farming in tropical regions. A sensitivity simulation using interannually varying OH shows that regional emission estimates by inversion are unaffected for the mid- and high latitude areas. We show that meridional shift in CH4 emissions toward the lower latitudes and the increase in CH4 loss by hydroxyl (OH) over the tropics finely balance out, which keep the CH4 gradients between the southern hemispheric tropical and polar sites relatively unchanged during 1988-2016. The latitudinal emissions shift is confirmed using the global distributions of the total column CH4 observations by satellite remote sensing. There is no evidence of emission enhancement due to climate warming, including the boreal regions, during our analysis period. These findings highlight key sectors for effective emission reduction strategies toward climate change mitigation.

アテネの疫病は, トゥキュディデスの『戦史』2巻には記載されているが, 『ヒポクラテス全集』(『全集』)には記載されていない.アテネの疫病は, 出血性, 発熱性ウイルス性感染症であるマールブルグ病, エボラ熱, 或いは, その類似疾患と考えられる.『戦史』と『全集』の色彩表現は関連性があったと推測される.『戦史』の3巻以降には色彩表現は殆ど認められないが, トゥキュディデスが疫病に罹り, その合併症であるブドウ膜炎による後天性色覚異常になったためと推測される.ヒポクラテスの生年をBC 460年頃とすると, アテネの疫病はBC 430年であるから, 彼は当時30歳代と推測される.『全集』にはアテネの疫病の記載がないが, ヒポクラテスがアテネの疫病に関与しなかったか, 或いは, 後に記載が脱落したかは不明である.

Organizations of clinical psychologist were organized on two occasions in Japan at the initiative of professional societies. The move toward professionalization in the 1960s used a strategy which gave priority to the acquisition of specialist status and autonomy than to obtaining a state-granted qualification. As a result, it failed to obtain the support of professionals working in the clinical field. However, in the 1970s, the whole clinical mental occupation reached consensus on the need to promote specialist status, from a sense of crisis brought about by the unwillingness of the Ministry of Health and Welfare and doctors to create a qualification. In the second professionalization in the 1980s, calls were made for the advancement of specialist status and the establishment of a training system. Thanks to a strategy of professionalization aimed at developing an educational field, it came to attain “miraculous” growth.This professionalization of clinical psychologists was based on the leadership of professional societies, which developed specialist attributes for the cultivation of a “science-profession” core based on a “dual strategy”, to gain professional status. The clinical psychologists used a dual strategy toward the Ministry of Health and Welfare and the Ministry of Education, expanded the market autonomously and produced a great deal of “science-profession.” However, it can be said that the professional society-led model has the danger of following the route of very unstable professionalization, which can be easily influenced of many domains although it has the potential for expanding new markets and the development of an autonomous training system.
