Due to the advantages of coastal areas in the fields of agriculture, transport, and fishing, increasingly more people are moving to these areas. Sea level information is important for these people to survive after extreme sea level events. With the recent improvements in computing and storage capacities, image analysis as a new measuring method is being rapidly developed and widely applied. In this paper, a multi-camera-based sea level height measuring system was built along Japan's coast and a deep-learning-based stereo matching method has been proposed for this system to complete 3D measurements. In this system, cameras are set with long base distances to ensure the long-distance monitoring system's precision, which causes a huge difference between the fields of view of the left and right cameras. Since most common network structures complete stereo matching by depth-wise cross-correlation between left and right images, they rely too much on the high-quality rectification of two images and fail on our long-distance sea surface images. We established a feature detection and matching network to realize sea wave extraction and sparse stereo matching for the system. Based on our previous result using the traditional method, the initial disparity was computed to reduce the search range of stereo matching. A training set with 785 pairs of sea surface images and 10,172 pairs of well-matched sea wave images was constructed to supervise the network. The experimental results verified that the proposed method can realize sea wave extraction and mask generation. It can also realize sparse matching of sea surface images regardless of poor rectification. [ABSTRACT FROM AUTHOR]

• Joint experimental campaigns carried out in QST lab in Naka, Ibaraki, Japan. • Full compensation of magnetic criss-cross deflection of beamlets obtained. • Non-uniform extraction assumed for interpreting the experimental results. • Numerical simulations can reproduce the experimental results with good accuracy. In the framework of the collaboration between Consorzio RFX (Padova, Italy) and QST (Naka, Japan) two experimental campaigns have been organized on the Negative Ion Test Stand (NITS) in Naka, employing an ITER-like multi-beamlet configuration. These campaigns were aimed at compensating for the undesired magnetic deflection of the ion beam. The experiments have clarified the influence of operating parameters on the optical properties of the ion beam. The physical phenomena acting on the optics have been investigated, in particular the effect of an asymmetry of the ion current density at meniscus. Comparisons with simulations have been made and the modeling has been improved consequently. During the second experimental campaign, a perfect compensation of the ion deflection has been achieved.

Background: Breech presentation is observed in 3–4% at term of pregnancy and is one of the leading causes of cesarean section. There is no established treatment for breech presentation before 36 weeks. A retrospective cohort study was conducted to demonstrate that the lateral position is effective for breech presentation. However, there are no randomized controlled trials evaluating lateral position management for breech presentation. Here, we described the methodology of a randomized controlled trial of a cephalic version for breech presentation in the third trimester by lateral postural management (BRLT study). Methods: The BRLT study is an open-label, randomized controlled trial with two parallel groups allocated in a 1:1 ratio to examine the lateral position management for breech presentation, as compared with expectant management care. An academic hospital in Japan will enroll 200 patients diagnosed with a breech presentation by ultrasonography between 28 + 0 weeks and 30 + 0 weeks. Participants in the intervention group will be instructed to lie on their right sides for 15 min three times per day if the fetal back was on the left side or lie on their left sides if the fetal back was on the right side. The instruction will be given every 2 weeks after confirmation of fetal position, and the lateral position will be instructed until the cephalic version, and after the cephalic version, the reverse lateral position will be instructed until delivery. The primary outcome is cephalic presentation at term. The secondary outcomes are cesarean delivery, cephalic presentation 2, 4, and 6 weeks after the instruction, and at delivery, recurrent breech presentation after cephalic version, and adverse effects. Discussion: This trial will answer whether the lateral positioning technique is effective in treating breech presentation and, depending on the results, may provide a very simple, less painful, and safe option for treating breech presentation before 36 weeks, and it may impact breech presentation treatment.

Benefiting from rich agricultural land, easy transport and fishing, etc., more and more people are moving to live in coastal areas, with more than 200 million people now living in coastal areas that are vulnerable to extreme sea level events. Sea level information is useful for coastal societies. Image measurement is rapidly developing as a new type of measurement tool. A multicamera-based sea level monitoring system along Japan's coast near the Pacific is proposed in this paper, and a long-distance sea wave matching method for this system is described. The whole system employs multiple binocular vision systems to take sea surface images and obtain the sea level height based on the disparity between the field of views of the left and right cameras, forming a local measurement and overall analysis monitoring system. Sea level monitoring requires a high processing accuracy and speed to realize a timely response to extreme events. Thus, the paper extracts sea waves and integrates a sea wave's appearance features as feature points and descriptors and pioneers the idea of searching deterministic features for fast image processing. The average stereo matching precision of the proposed method is up to 89.9% with a running time smaller than 40 ms for most pairs of images. Experiments on various real sea surface image pairs are conducted to validate the effectiveness of the proposed method. [ABSTRACT FROM AUTHOR]

Objective To investigate outcomes following the tapering or discontinuation of tocilizumab in patients with diffuse cutaneous SSc (dcSSc) in a real-world setting. Methods Fifteen patients who were treated with tocilizumab for dcSSc were selected from a single-centre cohort database and were evaluated for serial changes in the modified Rodnan total skin thickness score (mRSS) and predicted forced vital capacity (FVC) and the occurrence of clinical worsening events after the introduction of tocilizumab. Results Over 12 months of treatment with tocilizumab, the mRSS decreased from 20.4 ± 10.7 to 12.3 ± 8.5 (P   =  0.003) and FVC increased from 84.3 ± 13.7% to 88.5 ± 16.4% (P   =  0.04). Tocilizumab was tapered or discontinued in seven and three patients, respectively, after improvement in skin thickening without occurrence or progression of organ manifestations. One (14%) of seven patients who underwent tocilizumab tapering experienced a worsening of skin thickening, while all three patients who discontinued tocilizumab experienced a worsening of skin thickening and/or new development of pericarditis, arthritis, interstitial lung disease or pulmonary arterial hypertension. The additional patient who discontinued tocilizumab due to an adverse event experienced subsequent progression of multiple organ manifestations, including skin, lung, lower gastrointestinal and renal involvement, leading to mortality. Conclusion Our findings suggest potential benefits of prolonged tocilizumab use in dcSSc patients. The discontinuation of tocilizumab can lead to the progression of skin and visceral manifestations. Tapering rather than the discontinuation of tocilizumab is a viable option in dcSSc patients who experience remarkable clinical improvement. [ABSTRACT FROM AUTHOR]

Background: Never smokers in Asia have a higher incidence of lung cancer than in Europe and North America. We aimed to assess the cost-effectiveness of lung cancer screening with low-dose computed tomography (LDCT) for never smokers in Japan and the United States.Methods: We developed a state-transition model for three strategies: LDCT, chest X-ray (CXR), and no screening, using a healthcare payer perspective over a lifetime horizon. Sensitivity analyses were also performed. Main outcomes were costs, quality-adjusted life-years (QALYs), life expectancy life-years (LYs), incremental cost-effectiveness ratios (ICERs), and deaths from lung cancer. The willingness-to-pay level was US$100,000 per QALY gained.Results: LDCT yielded the greatest benefits with the lowest cost in Japan, but the ICERs of LDCT compared with CXR were US$3,001,304 per QALY gained for American men and US$2,097,969 per QALY gained for American women. Cost-effectiveness was sensitive to the incidence of lung cancer. Probabilistic sensitivity analyses demonstrated that LDCT was cost-effective 99.3-99.7% for Japanese, no screening was cost-effective 77.7% for American men, and CXR was cost-effective 93.2% for American women. Compared with CXR, LDCT has the cumulative lifetime potential for 60-year-old Japanese to save US$117 billion, increase 2,339,349 QALYs and 3,020,102 LYs, and reduce 224,749 deaths, and the potential for 60-year-old Americans to cost US$120 billion, increase 48,651 QALYs and 67,988 LYs, and reduce 2,309 deaths.Conclusions: This modelling study suggests that LDCT screening for never smokers has the greatest benefits and cost savings in Japan, but is not cost-effective in the United States. Assessing the risk of lung cancer in never smokers is important for introducing population-based LDCT screening. [ABSTRACT FROM AUTHOR]

Riding a bicycle under the influence of alcohol is illegal in Japan. Nevertheless, intoxicated bicyclists are frequently treated at hospital emergency departments for bicycle-related injuries. This patient population usually requires more hospital resources, even for relatively minor injuries. Therefore, we hypothesized that bicycle-related crashes involving bicyclists under the influence of alcohol cost more to treat than those that do not involve alcohol intoxication. The aim of the present study was to examine the costs associated with bicycle-related minor injuries and alcohol intoxication of the bicyclist. The study was conducted at the Tokyo Bay Urayasu Ichikawa Medical Center Emergency Department, Japan. All minor bicycle crashes involving 217 individuals aged ≥20 years treated from September 1, 2012 to August 31, 2013 were included in the analysis of data obtained from medical records. Variables included alcohol intoxication, sex, age, collision with a motor vehicle, Glasgow Coma Scale, injury severity score (ISS), laboratory tests, treatment of wounds, number of X-ray images, number of computed tomography scans, and medical costs. Multiple linear regression analysis was performed to evaluate the association between alcohol intoxication and medical costs. Seventy (32%) patients consumed alcohol, and the median medical cost was 253 USD (interquartile range [IQR], 164–330). Multivariable analysis showed that alcohol intoxication was independently associated with higher medical costs (p = 0.030, adjusted R-square value = 0.55). These findings support our hypothesis and should encourage authorities to implement comprehensive measures to prohibit bicycling under the influence of alcohol to prevent injuries and to reduce medical costs.

Throughout the nineteenth and twentieth centuries, the natural monopoly features of infrastructure industries, together with their strategic roles, have been important elements in state intervention. The aim of this paper is to evaluate what relative weight was attached to market failure problems on the one hand and geo-political factors on the other. For the period 1830-1939, how far were geo-political factors stronger than natural monopoly problems in accounting for the scale of intervention in the various countries of the Western World? How far did the policy instruments for security and market failure overlap? Whilst most of the infrastructure sectors are covered - including internal telecommunications, coal, gas, shipping, electricity and water - special attention is devoted to international submarine telegraph tables and railways. The paper concludes by demonstrating strong differences between Britain and USA on the one hand and Continental Europe plus Japan on the other. [ABSTRACT FROM AUTHOR]

This article examines some of the difficulties of universalistic science in situations of deep conflict over global nature, using empirical material pertaining to ongoing controversies in the context of Japanese whaling practices. Within global-scale whaling assemblages since the 1970s, science has become a ‘‘post-sovereign’’ authority, unable to impose any stable definition of nature on all actors. Instead, across spaces of deep antagonistic differences, anti- and pro-whalers now ontologically enact a multiplicity of mutually irreconcilable versions of whales. Empirically, the article attempts to map out a ‘‘cosmogram’’ of Japanese pro-whaling enactments of abundant and ‘‘killable’’ whales. Following the political ecology of Bruno Latour, the global-scale situation is conceptualized as one of cosmopolitics, the politics of forging a common world across divergences in nature-cultures. Pointing to tensions inherent in this concept, the article ends by suggesting a move toward ‘‘agonistic cosmopolitics,’’ in clarifying the constructive potentials of a Latourian anti-essentialist political ecology.

The superior competitiveness of the Japanese cotton industry became so obvious in the interwar period. The sources of the Japanese competitive advantage have thus collected considerable scholarly interest. A series of past studies stressed the significance of planned coordination and managerial innovations within the industry as a whole, and this involved their findings that the leading spinners and trading companies realised the efficient coordination. This paper inquires into the Meiji industrial leaders' conceptualisation of the new nature of entrepreneurial management. This entails an analysis of their early entrepreneurial leadership in the 1880s that provided the developing industry with a long-range plan for exponential growth since then. The essence of industrial competitiveness resided in the noticeable cognitive commonality in their sustainable core competence for the upcoming global competition. [ABSTRACT FROM AUTHOR]

Investigation of plant morphological features, pollen, and habitat have been made for two shrub species from Barrow, Alaska, namely Dryas integrifolia M. Vahl and Salix rotundifolia Trautv., both of which are endemic to the Arctic floristic area. The former species has small lanceolate or plate leaves, whereas the latter has rounded leaves with distinct veins, rich in vitamin C. Both have dwarf and sprawling habits. Pollen studies showed that the pollen grains of the two species are spheroidal to sub-spheroidal or prolate. The type of aperture was tricolporate; pollen size 26.3–31.3 μm; ornamentation finely reticulate under a light microscope (LM) and striate-reticulate under a scanning electron microscope (SEM) for D. integrafolia and finely reticulate under the LM and SEM for S. rotundifolia. Comparisons were made between the pollen from the same species from Arctic collections with those from China and Japan. Investigation of pollen morphology of tundra plants can provide significant data for comparative studies of fossil pollen and for the reconstruction of paleovegetation and paleoclimate in the Barrow area.

Since the mid-1990s, several Japanese cities have responded to the gradual increase in their non-Japanese populations by setting up ‘foreigners' assemblies’—venues in which representative foreigners, generally appointed by local officials and civilian representatives, can come together to discuss the social, economic, and cultural challenges of life in Japan. These bodies have no administrative power, but serve as advisory panels to local governments. This paper uses ethnographic studies of two such bodies—those of Kanagawa prefecture and Kawasaki city—to ascertain their role in contemporary Japanese society. I find that they have powerful relevance to three hotly debated issues: internationalization, local empowerment, and the development of civil society in Japan. [ABSTRACT FROM PUBLISHER]

An essay is presented on some issues in Japanese film historiography since the period 1925-1940. It also looks at the aspects that makes Japanese film style in the said period differs from the dominant norms of Hollywood cinema. The author also stresses how the impact of traditional culture explain any such difference. He also notes the influence of China and Pacific hostilities have on the development of film style.

In wartime Japan, folklore studies (minzokugaku) as an academic discipline emerged at the same time as the rise of the culture film (bunka eiga). Both helped mobilize peripheral areas and firmly created the image of a unitary nation. This paper focuses on Living by the Earth (Tsuchi ni ikiru, 1941), directed by Miki Shigeru, and its spinoff photo album titled People of the Snow Country (Yukiguni no minzoku, 1944). Miki filmed rural life and ordinary people in the Tohoku region under the strong influence of Yanagita Kunio, a founder of Japanese folklore studies, and published the photo album in collaboration with Yanagita. In this project, vanishing customs were paradoxically regarded as objects impossible to photograph. However, that paradox enhanced the value of the project and made it easier to construct an imagined national community through the discourse of folklore studies. [ABSTRACT FROM AUTHOR]

While the prevalence of smoking has steadily declined over time, the absolute numbers of lung cancer cases and deaths have continued to increase in Japan. We employed a simple mathematical model that describes the relationship between demographic dynamics and smoking prevalence to predict future epidemiological trends of lung cancer by age and sex. Never-smokers, smokers, and ex-smokers were assumed to experience different hazard of lung cancer, and the model was parameterized using data from 2014 and before, as learning data, and a future forecast was obtained from 2015 onwards. The maximum numbers of lung cancer cases and deaths in men will be 76,978 (95% confidence interval (CI): 76,630–77,253) and 63,284 (95% CI: 62,991–63507) in 2024, while those in women will be 42,838 (95% CI: 42,601–43,095) and 32,267 (95% CI: 32,063–32,460) in 2035 and 2036, respectively. Afterwards, the absolute numbers of cases and deaths are predicted to decrease monotonically. Our compartmental modeling approach is well suited to predicting lung cancer in Japan with dynamic ageing and drastic decline in smoking prevalence. The predicted burden is useful for anticipating demands for diagnosis, treatment, and care in the healthcare sector. [ABSTRACT FROM AUTHOR]

The article presents the concerns of critics on the near-infrared imaging spectroscopy (NIRS) developed by Masato Fukuda, a neuroscientist and psychiatrist at Gunma University Hospital and Hitachi Medical Corp., in Tokyo, Japan. Despite the ability of the NIRS to diagnose psychiatric disorders, critics alleged that NIRS only has few studies to warrant its readiness for clinical use. Tamagawa University neuroscientist Masahiko Haruno believes that the NIRS is not convincing to denote its efficacy.
