Liquid water, underwater volcanoes and possibly life forms have been suggested to be present beneath the estimated 10 km-thick ice shell of Europa, the Jovian satellite J2. Europa's possible ocean is estimated to be 100-200 km deep. Despite the great depth of the Europa's ocean, hydrostatic pressure at the seafloor would be 130-260 MPa, corresponding to 13-26 km depth of a theoretical Earth's ocean. The hydrostatic pressure is not beyond the edge of existing deep-sea technology. Here we propose exploration of Europa's deep-sea by the use of current technologies, taking a symbolic example of a deep submergence vehicle Shinkai 6500 which dives to a depth of 6.5 km deep (50 km depth of Europa's ocean). Shinkai 6500 is embarkable in the payload bay of the Space Shuttles in terms of size and weight for the transportation to a Low Earth Orbit (LEO). Secondary boost is needed for interplanetary flight from the LEO.On-orbit assembly of the secondary booster is a technological challenge. The International Space Station (ISS) and ISS-related technologies will facilitate the secondary boost. Also, ice shell drilling is a challenge and is needed before the dive into Europa's ocean. These challenges should be overcome during a certain leading time for matured experience in the ISS operation.

The activity concentration levels of 232Th, 238U, 40K and 137Cs in drinking water of different locations of Bangladesh were measured by using a high purity germanium (HPGe) detector. The average activity levels with one standard deviation (1σ) of 232Th, 238U and 40K were found to be 250±52mBq/L-1, 157±30mBq/L-1 and 9±3Bq/L-1, respectively. The 137Cs was detected only in 32% samples with an average 4±0.8Bq/L-1. A good correlation between the activities of 232Th and 238U was found. The radium equivalent activity (Raeq) and the representative level index (Iγr) due to natural radionuclides were also calculated. The average Raeq was found to be 1, 212±303mBq/L-1 and the average Iγr was found to be 10±3mBq/L-1. The annual individual committed effective dose (HE) due to intake of radionuclides in water was also evaluated and the average value was found to be 74±21μSv. The distribution of radionuclides was found to be normal except 137Cs. The radioactivity levels of these radionuclides were comparable to the corresponding reported values of drinking water of different countries. The results presented in this study may helpful in establishing a regulatory limit on radioactivity in drinking water in Bangladesh.

This paper examines the early stage of the geotectonic history of the Japanese Islands on the basis of finding hydrothermal jadeitite including zircons of ca. 520 Ma in serpentinite mélange of the Itoigawa-Omi area of the Hida-Gaien belt, Central Japan. Hydrothermal jadeitite contains euhedral jadeite in natrolite veins and patches, and consists of jadeite-albite and jadeite-natrolite without quartz. These minerals were crystallized from an aqueous fluid phase at the low-pressure and high-temperature side of the reaction boundary of albite = jadeite + quartz in the system NaAlSiO4-SiO2-H2O. The occurrence of rounded relict hornblende mantled by omphacite rimmed by fine-grained aggregates of jadeite in the matrix of jadeite and albite suggests a pervasive hydrothermal fluid flow, through which metabasite was extensively replaced by jadeitite. This rather high-temperature hydrothermal activity of ca. 520 Ma did not occur in an ordinary subduction zone but in a newly-formed mantle wedge suffering severe hydration from a subducting slab. Recently accumulated U-Pb ages of zircon of ca. 450-500 Ma from paleozoic sediments and granitic rocks of the Hida-Gaien belt were due to initiation of subduction followed by subduction zone magmatism. Protolith of serpentinite in the Hida-Gaien belt includes highly depleted harzburgite, thus requiring tectonic setting of a high-temperature-rift zone rather than a low-temperature-slow spreading ridge. Subduction was initiated at ca. 520 Ma along the boundary between low-density harzburgitic rift zone peridotite and lherzolitic spreading ridge peridotite with a slightly higher density, resulting in the common occurrence of harzburgitic serpentinite in the oldest part of the accretionary complex of Southwest Japan. An area including the Japanese Islands was born around the Yangtze block by the breaking up of the Rodinia supercontinent, because the oldest K-Ar age of biotite actinolit rock of 672 Ma (Matsumoto et al., 1981) and the subduction initiation of ca. 520 Ma are in accord with the paleogeographic history of the Yangtze block, and because ca. 300 Ma Renge schists of the Hida-Gaien belt did not suffer the ca. 280-200 Ma collision-type metamorphism of the Hida metamorphic belt that is an eastern extension of the suture between the Sino-Korea and Yangtze blocks.

Suo-Oshima, the main island in the west part of the Seto Inland Sea, lies between Japan proper and Sikoku. It is 158 square kilometres in area and of 406 inhabitants in every square kilometre. Because of the lack of the arable land, with its over-population, their daily life has been based on the utilization of the coast and its emigrants.The characters of the villages are as follows: Agenosho-Ura (Ura means ‘bay’) and Kuga-Ura are simply fishing villages, which were under the protection of the fishing right as Otate-Ura during the age of former clan. Otate-Ura gained its name because the villagers gave silver towards the government fund. Other Mura-Ura, called Ha-Ura in another name, are half-farming and half-fishing villages which have developed since the Meiji era.The chief products are sweet potatoes, mandarin oranges and dried sea-slugs. The villages are distributed in masses at the lower parts of the coast.The seine by sardine boats comes first in fishing. The individual administration of the first stage of Capitalism is carried on in Agenosho-Ura and in Kuga-Ura.The cooperative administration of stock system is in the other Mura-Ura. The fishing with a rod is for catching sea-breams, horse-mackerels, cuttlefish etc. Okikamurojima is famous for it. In Nasakejima of Yuda-Mura this way of fishing is practised by a Kajiko, child sea-man, employed for that purpose. The center of the net-fishing of sea-breams is Agenosho-Ura holding the 50 per cent of the whole island in the operation with roller. An octopus-trap is popular through-out the island, the west part of which is more famous.After all, in the fishing villages of Suo-Oshima they support a small way of living, relying upon their efficiency of labour, such as a side-job, emigration and a subsidiary work. As far as the number of fishing boats is concerned, in fishing villages it remains comparatively unchanged and the mechanization of the boats is advanced; while in half-farming and half-fishing villages the number has been rapidly increased since the Meiji era and their mechanization is unfavourable.

Awa Shijira fabric is a crepe cotton fabric made of cotton that is woven alternating the plain and the rib texture in the weft direction. Both the warp and weft yarns are usually sized with starch, before weaving. In the course of desizing process the fantastic crepe texture is formed due to the shrinkage of yarns especially in the weft direction. Thus, the geometrical roughness for the fabric desized tends to become obvious in the weft direction. The mechanical and surface properties for four kinds of traditional Awa Shijira fabrics were investigated comparing those for the plain cotton fabric. The roughness property measured based on KES has become marked in the weft direction for the fabrics having smaller values of the shear properties in the weft direction. Also, Shijira fabrics used in this study have shown higher frictional, bending and compression properties. Moreover, there observed no remarkable differences in the mechanical properties between nationally guaranteed traditional Shijira fabric and the one guaranteed by Tokushima prefecture.

It is known that bone marrow is a sensitive organ to ionizing radiation, and many patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) have been diagnosed in radiation-treated cases and atomic bomb survivors in Hiroshima and Nagasaki. The AML1/RUNX1 gene has been known to be frequently mutated in MDS/AML patients among atomic bomb survivors and radiation therapy-related MDS/AML patients. In this study, we investigated the AML1 mutations in radiation-exposed patients with MDS/AML among the residents near the Semipalatinsk Nuclear Test Site (SNTS), where the risk of solid cancers and leukemias was increased due to the radiation effects. AML1 mutations were identified in 7 (39%) of 18 radiation-exposed MDS/AML patients. In contrast, no AML1 mutation was found in 13 unexposed MDS/AML cases. The frequency of AML1 mutations in radiation-exposed patients with MDS/AML was significantly higher compared with unexposed patients (p < 0.05).We also found a significant correlation between individual estimated doses and AML1 mutations (p < 0.05). Considering these results, AML1 point mutations might be a useful biomarker that differentiates radio-induced MDS/AML from spontaneous MDS/AML.

The patient was hospitalized due to rapidly undulant fever and sore throat. Empirical antibiotic therapy was started, however, headache also occurred. Lumbar puncture disclosed polynuclear leukocyte-predominant pleocytosis indicating that the patient suffered from bacterial meningitis. The antibiotics therapy was increased, however, consciousness became impaired and erythema multiforme-like skin lesions appeared. T2-weighted brain magnetic resonance imaging showed high signal intensity in the brainstem. HLA testing revealed B54 and Cw1. The patient presented futures of Behçets disease at the same time as those of Sweets syndrome and it was difficult to distinguish between the two diseases. Administration of prednisolone showed remarkable effect.

Objective The prognosis of idiopathic pulmonary fibrosis (IPF) patients with acute exacerbation (AE) is reported to be extremely poor. Several clinical studies suggest that direct hemoperfusion with polymyxin B-immobilized fiber (PMX) may have beneficial effects on AE in patients with interstitial pneumonia (IP). The aim of this multicenter retrospective analysis was to investigate whether PMX treatment could provide improvement of oxygenation and survival benefits in IPF patients with AE. Methods We conducted a retrospective study of 160 IP patients (including 73 IPF) with AE treated by PMX at 18 institutions in Japan. PMX treatment was carried out twice. The total hemoperfusion time of PMX treatment was, on average, 12 hours. Data concerning oxygenation on PMX treatment and survival after AE were collected and analyzed. Results In IPF patients with AE, arterial oxygen tension (PaO2)/inspiratory oxygen fraction (FiO2), (P/F) ratio was significantly improved at the end of the 2nd treatment with PMX (173.9±105.4 to 195.2±106.8 Torr, p=0.003). White blood cell count was significantly reduced at the end of the 2nd treatment (13,330±7,002 to 9,426±5,188 /mm3, p<0.001). These clinical changes were also observed on analysis of all 160 IP patients with AE. The one- and three-month survival rates of IPF patients after AE were 70.1% and 34.4%, respectively. Conclusion PMX treatment may improve oxygenation and survival in IPF patients with AE. Prospective, controlled trials of PMX treatment for IPF with AE are warranted to verify this potential benefit.

評判分析などが自然言語処理技術によって進められているが,対象は主にWeb上のテキストであり,人文学的な批評文はその主たる対象となっていない.本研究では人文的な批評文の具体的批評対象を計量化することで,批評行為のより深い意味分析に向けての基礎固めを行う.本研究では批評文中の人名と作品に絞り,総合的作品である映画と演劇の批評において,誰についてどの作品について中心的に語られる傾向があるのかを計量し,カテゴリー分類と共起分析を行った.結果として演劇批評は集中的であり,映画批評は分散的・個別的であること,また演劇批評は強い芸術的指向性を持つことが明らかになった.

The risk of radiation-induced nodules is higher than the risk for radiation-induced cancer. Risk factors and specific modifiers of the dose-response relationship may vary among different populations and not be well recognized. Many thyroid studies have considered thyroid nodularity itself, but not specific morphological types of thyroid nodules. There are many specific types of thyroid nodules which follow a morphological classification of thyroid lesions, including some congenital and tumor-like conditions. Modern equipment and technique can help us to identify particular specific types of thyroid nodules. In this study we report some results of a clinically applicable approach to materials derived from three studies. From 1999 through 2002, we have screened 571 current residents from 4 exposed and 1 control village near the Semipalatinsk Nuclear Test Site area, who were of similar ages (<20) at the time of major radiation fallout events at the SNTS. Prevalent nodules were identified by ultrasound and fine-needle aspiration biopsy, cytopathology results. Analysis of ultrasound images and cytopathology of thyroid lesions among exposed and non-exposed population allowed us to distinguish some interesting ultrasound features for specific types of thyroid nodules. We believe that it would be interesting and possibly more informative for thyroid dosimetry studies to consider specific morphological types of thyroid nodules. We need more detailed research to clarify the feasibility of applying these findings for study of the dose-response relationship.
