El espacio arquitectónico de la contemporaneidad, específicamente en las primeras décadas del siglo XXI, ha buscado estrategias para acercarse a las dinámicas de la sociedad que la habita, catalogada por el sociólogo Zygmunt Bauman como líquida. El presente artículo tiene el propósito de evidenciar cómo la arquitectura de Junya Ishigami constituye una materialización tangible de la idea de liquidez en la arquitectura, convirtiéndose en referente para plasmar esta condición en el espacio habitable. El logro de este objetivo condujo a la investigación a traspasar referencias que transitan en la filosofía, como la apuesta de Bauman en la Modernidad Líquida. Estos planteamientos encuentran en los postulados del sociólogo, el fundamento necesario para explicar la impermanencia de la arquitectura a través de la liquidez. Las prácticas arquitectónicas de la postmodernidad muestran las fases germinales de lo que hoy puede conceptuarse como arquitectura y espacio líquido. Estas referencias y el análisis detallado de los proyectos de Ishigami: Table, Pabellón de la Bienal de Venecia y KAIT, demuestran que los aportes de su arquitectura a través de la indeterminación, la fluidez, la viscosidad, la transparencia y la tensión, constituyen las características fundamentales de un espacio líquido habitable.

Este texto analiza diferentes materializaciones arquitectónicas y escultóricas contemporáneas que se distinguen por un acercamiento relacional y contingente hacia todo aquello que nos rodea. Desde un acercamiento y articulación sensible hacia lo que coexiste, las configuraciones espaciales expuestas aquí son muestra de una manera de hacer, de una ética y una técnica, que tratan de habitar este mundo en relación. Eso es perceptible en el acercamiento y escucha hacia el entorno de la arquitectura de Junya Ishigami o en la configuración junto a las cosas de la escultura de suelo de Josu Bilbao. Son configuraciones estéticas que exponen, rescatando las palabras de Judith Butler, el carácter irremediablemente relacional y contingente de nuestra existencia. Y desde la interdependencia manifiesta hacia aquello que nos rodea y condiciona, estas configuraciones son ejemplo de lo que Adriana Cavarero propone como «geometría inclinada». Esta autora entiende por inclinación un acercarse que, asomándose fuera de sí, tiende al exterior, en manifiesta interdependencia estructural del sujeto hacia aquello con lo que coexiste. En este texto se expone esa geometría inclinada a través de las configuraciones espaciales de Junya Ishigami, Ryue Nishizawa, Gordon Matta-Clark y Josu Bilbao, como posibilidad de habitar un mundo inestable.

La descripción de los fenómenos atmosféricos según los grados de intensidad –vientos escala Beaufort 0, 1, 2,…– y su representación mediante diagramas sirven para medir futuras contribuciones energéticas y prevenir sequías e inundaciones a través de programas de simulación meteorológica como Real Flow o Flow Design en el entorno BIM. Como antecedente en el control de estos parámetros, determinados videos de obras de Land Art muestran cómo la acción del viento, la lluvia o los relámpagos potencian los efectos del tiempo sobre dichas obras como Air Art. Actualmente estas mediciones se utilizan en sistemas cerrados como las instalaciones domésticas Interior Weather de Philippe Rahm o Rain de Junya Ishigami o en sistemas abiertos como las redes de instalaciones Infraestructural Urbanism de Stan Allen o Landscape Urbanism de James Corner.

El presente artículo tiene por objeto indagar acerca de las dimensiones temporales del espacio arquitectónico. El estudio se centra en la percepción corporal y se sustenta tanto en referencias teóricas disciplinares como en la transversalidad de éstas con discursos filosóficos de la fenomenología, principalmente los de Merleau-Ponty, y críticos, como los de Benjamin, Sennett y Virilio, quiénes desde diferentes órbitas y momentos manifiestan un paulatino empobrecimiento de la experiencia sensible. Se parte de la hipótesis de que las cualidades del espacio arquitectónico pueden alterar la percepción de las dimensiones temporales. Desde un plano metodológico, el trabajo se precisa como una reflexión teórica que apelará a un doble caso de estudio con cualidades fuertemente vinculadas a la temática: El Workshop y la Plaza del Kanagawa Institute of Technology (KAIT) proyectados por el estudio japonés Junya Ishigami + associates. De los resultados se desprende que la naturaleza del espacio arquitectónico puede provocar diferentes estados perceptivos y que la escala temporal, relación poco atendida en las investigaciones de arquitectura, es un atributo significativo que podría estimular el desarrollo del proceso proyectual.

Streszczenie:

In this study, we present a novel method for quantifying dependencies in multivariate datasets, based on estimating the Rényi mutual information by minimum spanning trees (MSTs). The extent to which random variables are dependent is an important question, e.g., for uncertainty quantification and sensitivity analysis. The latter is closely related to the question how strongly dependent the output of, e.g., a computer simulation, is on the individual random input variables. To estimate the Rényi mutual information from data, we use a method due to Hero et al. that relies on computing minimum spanning trees (MSTs) of the data and uses the length of the MST in an estimator for the entropy. To reduce the computational cost of constructing the exact MST for large datasets, we explore methods to compute approximations to the exact MST, and find the multilevel approach introduced recently by Zhong et al. (2015) to be the most accurate. Because the MST computation does not require knowledge (or estimation) of the distributions, our methodology is well-suited for situations where only data are available. Furthermore, we show that, in the case where only the ranking of several dependencies is required rather than their exact value, it is not necessary to compute the Rényi divergence, but only an estimator derived from it. The main contributions of this paper are the introduction of this quantifier of dependency, as well as the novel combination of using approximate methods for MSTs with estimating the Rényi mutual information via MSTs. We applied our proposed method to an artificial test case based on the Ishigami function, as well as to a real-world test case involving an El Nino dataset.

170 Background: The prognosis of gastric cancer with peritoneal metastases remains dismal. Ishigami et al. have recently published a phase III study (PHOENIX-GC) aimed at clinical efficacy of intraperitoneal paclitaxel (PTX), which established intraperitoneal chemotherapy as a decent option for gastric cancer with peritoneal dissemination. According to this report, we have used various regimens of intraperitoneal chemotherapy, adjusted mainly based on previous treatments. Methods: Data from 82 patients with gastric cancer with peritoneal metastases who underwent intraperitoneal chemotherapy in our institute from February 2012 to July 2017 were retrospectively analyzed. The progression free survival (PFS), the overall survival (OS) and the 1-year survival rate were stratified by prior treatments. Results: Of the 82 patients, 38 (46.3%) were chemotherapy-naïve. The intraperitoneal regimens were assigned mainly according to the prior treatment: intraperitoneal PTX plus S-1/PTX was the most frequent (39 cases), followed by intraperitoneal PTX plus intravenous PTX (17 cases), intraperitoneal PTX only (6 cases), and the rest. The median PFS for the chemotherapy-naïve group and the previously treated group was 6.9 and 4.1 months, and the median OS was 12.8 and 7.9 months, and the 1-year survival rate was 72.2% and 34.4%, respectively. 10 patients (12.2%) achieved conversion surgery after confirmed complete response in the peritoneal metastases. Among these 10 patients, the median survival time is 22.7 months (7.6+-47.7). Adverse events were also analyzed for each regimen, as for intraperitoneal PTX plus S-1/PTX, leukopenia, neutropenia and anemia occurred frequently. All regimens were comprehensively tolerable, and there were no treatment-related deaths. Conclusions: Intraperitoneal chemotherapy is a promising and feasible option for gastric cancer with peritoneal dissemination. There were several cases with long-term prognosis where conversion surgery was achieved.

Abstract Dysregulated RNA splicing factors have been widely reported in tumorigenesis, but their involvement in pancreatic ductal adenocarcinoma (PDAC) is not well understood. We found that two proteins involved in different stages of spliceosome assembly contribute to PDAC tumorigenesis by regulating alternative splicing, either through direct or indirect interaction with RNA. First, we showed that the splicing factor SRSF1—an RNA-binding protein involved in early spliceosome assembly—can induce pancreatitis and accelerate KRASG12D-mediated PDAC by activating the MAPK pathway. Moreover, the expression of SRSF1 decreased in morphologically normal pancreatic cells expressing KRASG12D to maintain cellular homeostasis. Second, we found that breast cancer amplified sequence 2 (BCAS2, also known as SPF27)—a spliceosome scaffold protein associated with conformational changes—also contributes to PDAC progression. Although BCAS2 does not bind RNA directly, it can regulate alternative splicing events in a sequence-specific manner by promoting the usage of specific 5’ splice sites. BCAS2 promotes the inclusion of exon 21, which has a weak 5' splice site, in the SOS Ras/Rac Guanine Nucleotide Exchange Factor 1 (SOS1) pre-mRNA, resulting in a more oncogenic isoform. These studies not only improve our understanding of the oncogenic role of aberrant alternative splicing, but also provide insights into the mechanisms of alternative-splicing regulation at different stages of spliceosome assembly.

Nowadays artificial light with optimized spectrum is used in many different applications. For instance, it is widely used in museums and exhibitions to illuminate the art. Moreover, such light stimulates the growth of plants, or can be applied in industry and healthcare. To achieve the best results for each application, adjusting of dedicated spectrum is required, that is a complicated task. The ongoing research is focused on simplifying this process. In this paper we present the developed lamp with programmable spectrum, and its user interface. Predicted and measured output spectra are investigated.

SUMMARYWe previously revealed that Japanese encephalitis virus (JEV) seroprevalence was 4·5% in pigs on Ishigaki Island from 2005 to 2007. However, a partial E gene sequence (151 bp) of the JEV genome (JEV/sw/Ishigaki/1/2005) was detected in one pig. Phylogenetic analysis showed that JEV/sw/Ishigaki/1/2005 belonged to genotype III and to the same lineages isolated in Taiwan from 2006 to 2008. Serum samples were collected from 128 pigs on Ishigaki from 2009 to 2010, 24 wild boars on Ishigaki from 2008 to 2010, and 117 wild boars on Iriomote Island from 2008 to 2010. Four (3·1%) pigs on Ishigaki were positive for JEV antibody, but all wild boars on the island were negative. Fifty-two (44·4%) wild boars on Iriomote were positive for JEV antibody, in contrast to a seroprevalence of 3·7% in 2000 and 2004. JEV on Iriomote and/or in Taiwan might be related to transmission on Ishigaki.

Abstract Ishigamide was isolated as a metabolite of a recombinant strain of Streptomyces sp. MSC090213JE08 and its unsaturated fatty acid moiety has been confirmed in vitro to be synthesized by a type II PKS. Biosynthesis of such a highly reduced polyketide by a type II PKS is worthy of note. However, absolute configuration of ishigamide remained unknown. (R)-Ishigamide was synthesized enantioselectively employing Stille coupling and Wittig reaction between three units, vinyl iodide, stannyldienal, and Wittig salt. Stereochemistry of natural ishigamide was determined to be R by chiral HPLC analysis comparing with the synthesized standard.

Abstract. The southwestern Ryukyu area east of Taiwan Island is an arcuate boundary between Philippine Sea Plate and Eurasian Plate. The topographic features in the area are characterised by (1) a large-scale amphitheatre off Ishigaki Island, just on the estimated epicentre of the tsunamigenic earthquake in 1771, (2) lots of deep sea canyons located north of the amphitheatre, (3) 15–20 km wide fore-arc basin, (4) 15–20 km wide flat plane in the axial area of the trench, (5) E-W trending half grabens located on the fore-arc area, etc., which were revealed by several recent topographic survey expeditions. The diving survey by SHINKAI6500 in the fore-arc area on a spur located 120 km south of Ishigaki Island was carried out in 1992. The site is characterised dominantly by rough topography consisting of a series of steep slopes and escarpments. A part of the surface is eroded due to the weight of the sediment itself and consequently the basement layer is exposed. The site was covered with suspended particles during the diving, due to the present surface sliding and erosion. The same site was resurveyed in 1997 by ROV KAIKO, which confirmed the continuous slope failure taking place in the site. Another example that was observed by KAIKO expedition in 1997 is a largescale mud block on the southward dipping slope 80 km south of Ishigaki Island. This is apparently derived from the shallower part of the steep slope on the southern edge of the fan deposit south of Ishigaki Island. The topographic features suggest N-S or NE-SW tensional stress over the whole study area. In this sense, the relative motion between the two plates in this area is oblique to the plate boundary. So, the seaward migration of the plate boundary may occur due to the gravitational instability at the boundary of the two different lithospheric structures. This is evidenced by a lack of accretionary sediment on the fore-arc and the mechanism of a recent earthquake which occurred on 3 May 1998 in the Philippine Sea Plate 250 km SSE of Ishigaki Island.

Abstract In general, population genetics theory predicts that a fragmented smaller population will contain relatively less genetic diversity than a larger population, and so will have a higher rate of genetic fixation due to random genetic drift or inbreeding. However, in this study, having analysed the genetic structure of the mitochondrial DNA COI region between two closely related euphaeid damselflies, we obtained unexpected results which contradict the theoretically expected patterns. Despite their geographical proximity, Euphaea yayeyamana was clearly genetically isolated on Ishigaki and Iriomote Islands, and no haplotype crossovers were observed. Even within each island, several diverse haplotypes were observed, indicating a significantly high haplotype intra-island diversity. However, the genetic diversity within Taiwan’s population of Euphaea formosa was significantly lower than that within either Ishigaki or Iriomote Island, even though Taiwan is significantly larger, with high mountain ranges that reach c. 4000 m a.s.l. and an abundance of habitats, all factors that should contribute to high genetic diversity. The current low diversity status for Taiwan’s population may be due to genetic bottleneck effects. In contrast, despite the very small population sizes of Ishigaki and Iriomote Islands coupled with the effects of glacial and interglacial geological events, they have maintained markedly high genetic diversity.

The Ryukyu flying fox (Pteropus dasymallus) is distributed throughout the island chain spanning across southern Japan, Taiwan, and possibly the Philippines. AlthoughP.dasymallusis listed as VU (vulnerable) in the IUCN Red List, only few genetic works have been conducted to support its conservation. In this study we analyzed 19 markers (mtDNA haplotypes and 18 microsatellite markers) to evaluate genetic diversity and investigate the genetic structure of this species. mtDNA analysis was conducted with 142 DNA remote samples, mostly from faeces, and wing tissues collected on eight islands (Miyako, Ishigaki, Kohama, Kuroshima, Hateruma, Taketomi, Iriomote, Yonaguni). 39 haplotypes were identified in 526bp of the control region, and haplotype network showed no clear genetic structure. Microsatellite analysis was also conducted with 155 samples collected on six islands (Miyako, Ishigaki, Kohama, Taketomi, Iriomote, Yonaguni). It showed that the Yonaguni population exhibits low genetic diversity, high inbreeding, and clear genetic differentiation from other populations. Gene flow between Ishigaki and Miyako through small stepstone islands might be preventing inbreeding of the Miyako population. We provide for the first time indirect proof of long-distance inter-island dispersal in the Ryukyu flying fox and revealed genetic diversity, gene flow and genetic differentiation among the archipelago’s populations. These results will be useful for delineating conservation units and designing specific conservation policies for each island based on metapopulation genetic structure.

Streszczenie:

The concept of intercorporeality refers to a fundamental function of an individual’s body that enables them to be or feel interconnected with other human beings. Researchers at the Department of Sport and Health Science, Tokai Gakuen University, Japan, led by Professor Kenji Ishigaki are exploring whether intercorporeality can help inform the physical education, play and sports included in the school curriculum. They hope that by encouraging ‘corporeal feeling’ towards others, children can gain a better sense of morality and belonging. This, in turn, can improve mental health and engagement with physical education. Ishigaki believes that the intercorporeal approach will reveal what kind of exercise play will contribute to the development of children’s morality or what kind of ‘corporeal feeling’ is important for the children’s body. The expectation is that philosophical analysis of these ‘corporeal feelings’ will shed light on the types of exercise, play and sports that should be arranged and incorporated into the Japanese school curriculum. An important idea for Ishigaki and the team is that when we think in the same way as others do about a particular thing, an intersubjective ‘we’ is established but in practising physical education and exercise in sports, a different kind of ‘we’ is established. This is the the intercorporeal ‘we’ as corporeal feeling that is unknowingly generated in the dimension of the human body,’

Ishigaki Yaeyaman, a heavily minoritized Southern Ryukyuan language, is not a language of commerce, education, media, or government validated by the socioeconomic center. Nevertheless, it holds a certain value for a group of people in Ishigaki City that is intangible and deeply personal. In keeping with the goal of this special issue—to step out of the established dichotomies that impede the vision and practice of Ryukyuan language learning—this work sheds light on the ideologies and practices of new speakers of Ishigaki Yaeyaman, who traverse a ‘third space’ in their use of the language between public-and-private, polite-and-rude, spoken-and-written, and Japanese-and-Ryukyuan. It builds on the author’s findings, including field observations made during doctoral research at University of the Ryukyus. A participatory action research methodology is employed, drawing upon qualitative data from semi-structured personal interviews and the in-person observation of Master–Apprentice language learning sessions within a local grassroots initiative begun in December 2019. The analysis suggests a need to break away from the dichotomies dictating the environment and situations in which new speakers may interact with traditional speakers and among themselves. This is recommended to take the form of Master–Apprentice training in a context that encourages the transformation of language attitudes and awareness, creating a ‘safe space’ that is dialogic, collaborative, and transdisciplinary.

Skeletons of hermatypic corals (e.g., Porites) might have enormous potential as a high-resolution paleomagnetic recorder owing to their rapid and continuous growth over hundreds of years at a rate of up to 2 cm/year, although typical corals show an extremely weak intensity of remanence and low stability. We found that coral tsunami boulders with negligible amounts of calcite on Ishigaki Island show a measurable intensity of remanence; thus, we attempted to characterize the magnetic assemblages in this coral skeleton to determine whether it is of biogenic or detrital magnetite using first-order reversal curve (FORC) measurements, ferromagnetic resonance (FMR) spectroscopy, and petrological observations through field-emission type scanning electron microscope (FE-SEM) with an acid treatment. The FMR derivative spectra of coral skeleton samples represent multiple derivative maxima and extended low-field absorption, indicating the presence of intact biogenic magnetite chains. FORC diagrams represent a “central ridge” signature with a vertical spread. These FMR and FORC features indicate the magnetization of these coral skeletons that are mainly created using intact biogenic magnetites and mixtures of grains from collapsed biogenic magnetites, pseudo-single domain grains, and multi-domain grains such as detrital magnetite. FE-SEM observations confirm the presence of a chain-like structure of iron oxides corresponding to the features of biogenic magnetite. Therefore, the magnetic mineral assemblage in coralline boulders from Ishigaki Island consists of dominant biogenic-origin single-domain magnetite and a trace amount of detrital component, indicating that fossil coral skeletons in Ishigaki Island have potential for utilization in paleomagnetic studies.

AbstractThe Ishigaki high-pressure schist belt in the southern Ryukyu Arc is correlated with the Suo high-pressure schist belt in southwest Japan. The former metamorphic sequence is composed mainly of basic and pelitic schists and is subdivided into three zones, the lower-grade zone A, the medium-grade zone B and the high-grade zone C, based on the mineral assemblages of the basic schists. The K–Ar phengite age gives 188–205 Ma for zone A, 196–206 Ma for zone B and 208–220 Ma for zone C, while the apparent d002 spacing of carbonaceous materials is 3.590–3.437 Å, 3.415–3.390 Å and 3.387–3.364 Å, respectively. The age–d002 relationships suggest that the ages become older with increasing metamorphic temperature. This positive age–temperature relationship in the Ishigaki area contrasts with a negative relationship in the Nishiki area in the Suo belt. The two areas also display a contrasting thermal structure with the former area having an inverted metamorphic gradient and the latter displaying a normal thermal structure. These contrasting age–temperature–structure relationships in the metamorphic belt could be due to different tectonic styles relating to the exhumation of the metamorphic sequences. We suggest that the ages obtained are related directly to the ductile deformation history of the matrix phengite below the closure temperature (500°C) during exhumation of the host rocks. The duration from the beginning of exhumation to the apparent resetting of the phengite K–Ar system was different between the two metamorphic sequences, and significantly longer in the Ishigaki than the Nishiki.

DNA fingerprinting using random amplified polymorphic DNA (RAPD) markers was employed to investigate the genetic variation within and among populations of Miscanthus Anderss. sinensis var. condensatus (Hack.) Makino, an apomictic grass distributed along the coasts of Taiwan and Ryukyu Islands. A total of 250 plants from three Taiwanese populations (Southeast Coast, Orchid Islet, and Green Islet) and two populations from Ryukyu (Ishigaki and Amami-O-Shima Islets) were sampled. The amplified products of 40 random primers showed monomorphic banding patterns within all populations as well as among the three populations from Taiwan. Low genetic variation (with only two polymorphic loci), but significant differentiation, was detected between populations from Taiwan and Ryukyu (ΦCT = 0.864) and between populations (ΦST = 1.0) from Ishigaki and Amami-O-Shima Islets. In contrast, a high level of variation was exhibited in the outcrossing Miscanthus sinensis var. glaber (Nakai) Li. In addition to apomictic reproduction, low genetic variation across populations of M. sinensis var. condensatus may be a result of high salinity acting as a selective agent. With the cost of reduced genetic heterogeneity, apomixis may have provided a mechanism for avoiding the transmission of endophytic fungi. The phytogeographic pattern of M. sinensis var. condensatus, as reflected by the RAPD data, likely represents isolation between Taiwan and Ryukyu since the mid-Pleistocene.Key words: apomixis, Miscanthus sinensis var. condensatus, phytogeography, population differentiation, RAPD, system of mating.

Crown-of-thorns starfish, Acanthaster planci (COTS), are common in coral reefs of Indo-Pacific Ocean. Since they are highly fecund predators of corals, periodic outbreaks of COTS cause substantial loss of healthy coral reefs. Using complete mitochondrial DNA sequences, we here examined how COTS outbreaks in the Ryukyu Archipelago, Japan are reflected by the profile of their population genetics. Population genetics of the blue starfish, Linckia laevigata, which lives in the Ryukyu Archipelago, but not break out and the northern Pacific sea star, Asterias amurensis, which lives in colder seawater around the main Islands of Japan, were also examined as controls. Our results showed that As. amurensis has at least two local populations that diverged approximately 4.7 million years ago (MYA), and no genetic exchanges have occurred between the populations since then. Linckia laevigata shows two major populations in the Ryukyu Archipelago that likely diverged ∼6.8 MYA. The two populations, each comprised of individuals collected from coast of the Okinawa Island and those from the Ishigaki Island, suggest the presence of two cryptic species in the Ryukyu Archipelago. On the other hand, population genetics of COTS showed a profile quite different from those of Asterias and Linckia. At least five lineages of COTS have arisen since their divergence ∼0.7 MYA, and each of the lineages is present at the Okinawa Island, Miyako Island, and Ishigaki Island. These results suggest that COTS have experienced repeated genetic bottlenecks that may be associated with or caused by repeated outbreaks.

AbstractAs Typhoon Goni (2015) passed over Ishigaki Island, a maximum gust speed of 71 m s−1 was observed by a surface weather station. During Typhoon Goni’s passage, mountaintop radar recorded antenna elevation angle oscillations, with a maximum amplitude of ~0.2° at an elevation angle of 0.2°. This oscillation phenomenon was reflected in the reflectivity and Doppler velocity fields as Typhoon Goni’s eyewall encompassed Ishigaki Island. The main antenna oscillation period was approximately 0.21–0.38 s under an antenna rotational speed of ~4 rpm. The estimated fundamental vibration period of the radar tower is approximately 0.25–0.44 s, which is comparable to the predominant antenna oscillation period and agrees with the expected wind-induced vibrations of buildings. The reflectivity field at the 0.2° elevation angle exhibited a phase shift signature and a negative correlation of −0.5 with the antenna oscillation, associated with the negative vertical gradient of reflectivity. FFT analysis revealed two antenna oscillation periods at 0955–1205 and 1335–1445 UTC 23 August 2015. The oscillation phenomenon ceased between these two periods because Typhoon Goni’s eye moved over the radar site. The VAD analysis-estimated wind speeds at a range of 1 km for these two antenna oscillation periods exceeded 45 m s−1, with a maximum value of approximately 70 m s−1. A bandpass filter QC procedure is proposed to filter out the predominant wavenumbers (between 40 and 70) for the reflectivity and Doppler velocity fields. The proposed QC procedure is indicated to be capable of mitigating the major signals resulting from antenna oscillations.
