概要: In this photo essay, we take you on a visual journey to Akina Village in Amami Ōshima, Japan, through the work of Futosh i Hamada, an award-winning island photographer and ecologist. Based on the artist’s Mura (2001) photographic work that documented the natural cycle of the village’s rice cultivation and the harvest festivals associated with it, we aim to explore the concept of the island’s ecocultural identity as it manifests through the artist’s and the community’s unique connection with the island nature and culture. As Akina is the last remaining village on the island where rice cultivation is still taking place, and linked to the harvest festivals, the visual documentation of these practices provides us a rare glimpse into what was once an integral part of Amami’s natural, socio-cultural, and spiritual/animistic islandscape before sugarcane was imposed on the islanders by mainland Japanese agricultural interventions and impositions. 続きを見る

概要: The Nixon administration tried to limit textile imports from Japan to protect the US industry. In return, the US would agree to return the administrative rights of the Ryukyu Islands, including Okinawa. This stood as the most important agenda item for the Sato administration in Japan. To get such a textile concession agreement from the Japanese, US offi cials had considered refusing to sign the Okinawa Reversion Treaty or to return the Senkaku Islands. However, Nixon and his advisors opposed those options since they were afraid that a confrontation over trade would spill over into defense and other security issues. Linkages among different issue areas, such as trade and security, tend to be precarious since the leverage obtained could be unclear, and various repercussions might be diffi cult to measure. When one country attempts to solve its domestic issues by linking them to other sensitive topics, domestic opposition might disrupt negotiation of the agreement or cause it to be rescinded. 続きを見る

概要: The repurposing of former military land is essential to the constant reformations of the US military’s immense footprint in Okinawa. The local forms of land-use planning that guide these conversions remain infl uenced by the land rent-structure that emerged out of the militarized colonial settlement of the postwar decade and the uprisings it inspired. In this article, I ask how colonial dispossession in militarized contexts shapes urban planning processes and outcomes for closed military sites. Using qualitative research in Central Okinawa, I argue that planning goals seeking to restore public access to demilitarized sites are hindered where there is a predominance of private property claims to base land. This work contributes to an understanding of planning’s colonial formations, especially as they operate through militarism, and deepens our understanding of the range of considerations that planners must make when approaching the redevelopment of militarized land in indigenous places. 続きを見る

概要: Encysted metacercariae of a poorly investigated digenean, Scaphanocephalus adamsi, are commonly found on fins and under scales of coastal marine fishes in the Ryukyu Archipelago, Japan. We here report its host range, focusing on commercial fishes landed at the Yaeyama Fisheries Cooperative of Ishigaki Island. During the study period from February 2017 to May 2018, metacercariae were recovered from four species of goatfishes (Mullidae spp.) and 14 species of parrotfishes (Scaridae spp.), with new host records for four species. Since metacercaria infection decreases the rating of fish prices in local fishery cooperatives due to their poor appearance, the occurrence conditions in newly recognized hosts should be evaluated to help protect commercial values.<br />吸虫の一種Scaphanocephalus adamsiは, フィリピン周辺および琉球列島沿岸に生息する海産魚類のヒレや鱗下に被嚢幼虫(メタセルカリア)として寄生する. 市場に並ぶ水産魚種への寄生も日常的に確認されるため,宿主範囲を含めた情報の蓄積が求められる. そこで本稿では, 八重山漁協において被嚢幼虫が認められたヒメジ類およびブダイ類を報告する. 2017年2月から2018年5月までの間に, 4種のヒメジ科魚類および14種のブダイ科魚類から本種幼虫が得られ, 4種が新宿主記録に該当することが明らかとなった. 被嚢幼虫の存在は魚価低下の一要因であるため, 各宿主魚類における寄生条件を明らかにし, 価格安定へ向けた取り組みがなされる必要がある. 続きを見る

概要: During a recent ecological survey of the reefs of Iwotorishima Island in the Ryukyu Islands, three species of zoantharia ns were noted. Past knowledge of zoantharians from this island is sparse, and only one species has previously been reported; Palythoa tuberculosa. In our survey, we also noted Palythoa tuberculosa, along with two other zoantharian species recorded for the first time from this island (Palythoa mutuki and Zoanthus sansibaricus).<br />硫黄鳥島におけるスナギンチャク類の過去の記録はPalythoa tuberculosaイワスナギンチャク1種と少ない. 最近実施したサンゴ礁生態調査において,イワスナギンチャクに加え, 硫黄鳥島初記録となるPalythoa mutuki とZoanthus sansibaricusキクマメスナギンチャクも記録した. 続きを見る

概要: Background:Smoking among Japanese adolescents has decreased noticeably. However, little is known whether the decreasing trend in adolescent smoking can be seen across all socioeconomic status (SES) groups. This study aimed to examine trends in socioeconomic inequalities in smoking among Japanese adolescents between 2008 and 2016. Methods:We conducted a repeated cross-sectional study using data from three surveys of high school students in Okinawa, Japan, in 2008, 2012, and 2016. The study participants consisted of 7902 students in grades 10 through 12 (15–18 years). Smoking was assessed as current cigarette use. SES indicators included familial SES (parental education and family structure) and student’s own SES (school type). To evaluate absolute and relative inequalities, prevalence differences (PDs) and ratios (PRs) between low and high SES groups were estimated. The slope index of inequality (SII) and relative index of inequality (RII) were also calculated. Results:Smoking prevalence among boys and girls significantly declined from 11.5% and 6.2% in 2008 to 4.7% and 1.9% in 2016, respectively. Similar decreasing trends in smoking were found among most of the SES groups. The PDs and SII for parental education in boys and family structure in girls decreased over time while those for school type persisted among boys and girls. The PRs and RII for school type in boys increased while those for other SES indicators among both sexes remained stable over time. Conclusions:Smoking among Japanese adolescents has been declining and time trends of socioeconomic inequalities in smoking varied by absolute and relative measures. Further policies and/or interventions to reduce smoking inequalities should focus on the context of schools, especially in vocational high schools. 続きを見る

概要: The effect of solutal Marangoni convection on flow instabilities in the presence of thermal Marangoni convection in a Si-Ge liquid bridge with different aspect ratios A_s has been investigated by three-dimensional (3D) numerical simulations under zero gravity. We consider a half-zone model of a liquid bridge between a cold (top plane) and a hot (bottom plane) disks. The highest Si concentration is on the top of the liquid bridge. The aspect ratio (A_s) drastically affects the critical Marangoni numbers: the critical solutal Marangoni number (under small thermal Marangoni numbers (Ma_TA_s<_~1800)) has the same dependence on As as the critical thermal Marangoni number (under small solutal Marangoni numbers (400<_~Ma_CA_s<_~800)), i.e., it decreases with increasing A_s. The azimuthal wavenumber of the traveling wave mode increases as decreasing A_s, i.e., larger azimuthal wavenumbers (m=6,7,11,12, and 13) appear for A_s=0.25, and only m=2 appears when A_s is one and larger. The oscillatory modes of the hydro waves have been extracted as the spatiotemporal structures by using dynamic mode decomposition (DMD). The present study suggests a proper parameter region of quiescent steady flow suitable for crystal growth for smaller aspect ratios of the liquid bridge. 続きを見る
