A 25-year-old Japanese female was admitted with fever, headache and nausea. She had recurrent fever every 48 hours and a CT scan revealed splenomegaly. An automated hematology analyzer displayed an error message of platelet aggregation. The laboratory technician checked a blood smear with a microscope and found Plasmodium parasites. Suspecting malaria infection, we reconfirmed her travel history and found that she had visited India and Nepal 8 months ago. The PCR test revealed that she was infected with Plasmodium vivax (P. vivax) malaria. The average incubation period is 2-4 weeks for P. vivax malaria, but some cases of P. vivax malaria show a much longer incubation period up to a maximum of about 12 months. When a patient has malaria-like symptoms, it is of utmost importance to confirm his/her travel history within at least the previous 1 year.

In this paper, I clarify the significance of dark tourism from the viewpoint of sociomateriality. For that purpose, I will proceed with consideration of the keyword “experience economy” that is related to both dark tourism and sociomateriality. Therefore, this paper is structured as follows. First, the concept of dark tourism is reaffirmed. Next, the relationship between dark tourism and the experience economy is examined. After discussing the relationship between the experience economy and social materiality, we examine the relationship between dark tourism and social materiality.

Delanian et al. reported the efficacy of pentoxifylline-tocopherol-clodronate (PENTOCLO) treatment for osteoradionecrosis (ORN) of the mandible in 2011. Spontaneous sequestration and epithelialization of the mandibular lesion are induced by this method. We report a case of osteoradionecrosis of the mandible which responded to treatment with PENTOCLO. A 60-year-old man was referred to our department with persistent mandibular ORN after definitive chemoradiotherapy for oropharyngeal carcinoma (T2N0M0). Periodontitis of the right second molar caused ORN, followed by pathological fracture. PENTOCLO treatment was started following 4-week antibiotic therapy. The sequestrum spontaneously separated with mucosal epithelialization two months after the treatment started. The second molar was removed at 11 months because of its increasing mobility. The extraction socket had epithelized and computed tomography (CT) showed that the pathological fracture had healed. No adverse events occurred during this treatment course. PENTOCLO may be an organpreserving treatment option for ORN of the mandible.

This study investigates the quality of the Japanese 55-year Reanalysis (JRA-55), which is the second global reanalysis constructed by the Japan Meteorological Agency (JMA), by comparing it with other reanalyses and observational datasets. Improvements were found in the representation of atmospheric circulation on an isentropic surface and in the consistency of momentum budget based on the mass-weighted isentropic zonal mean method. The representation of climate variability in several regions was also examined. In the tropics, the frequencies of high spatial correlations with precipitation, which were estimated using the Tropical Rainfall Measuring Mission Multisatellite Precipitation Analysis, are clearly higher in JRA-55 than in JRA-25. The results indicate that JRA-55 generally improved the representations of phenomena on a wide range of space-time scales, such as equatorial waves, and transient eddies in the storm track regions, compared with JRA-25 during the satellite era. Moreover, JRA-55 improved the temporal consistency compared with the older reanalyses throughout the reanalysis period. In the stratosphere, we found larger discrepancies between reanalyses for the extra-tropical stratosphere during the Southern Hemisphere (SH) winter. Comparisons with radiosonde temperature revealed that JRA-55 has a smaller bias in temperature than the other reanalyses in the extra-tropical SH winter before 1979. Some issues in JRA-55 were also identified. The amplitude of equatorial waves and Madden-Julian oscillation in JRA-55 are weaker than in the other reanalyses. JRA-55 shows unrealistic strong cooling in South America and Australia, although the spatial distribution of the long-term temperature trends in JRA-55 is the closest to an observational dataset of global historical surface temperature.

Similarity search is an important and fundamental problem, and thus widely used in various fields of computer science including multimedia, computer vision, database, information retrieval, etc. Recently, since loitering behavior often leads to abnormal situations, such as pickpocketing and terrorist attacks, its analysis attracts increasing attention from research communities. In this paper, we present AntiLoiter, a loitering discovery system adopting efficient similarity search on surveillance videos. As we know, most of existing systems for loitering analysis, mainly focus on how to detect or identify loiterers by behavior tracking techniques. However, the difficulties of tracking-based methods are known as that their analysis results are heavily influenced by occlusions, overlaps, and shadows. Moreover, tracking-based methods need to track the human appearance continuously. Therefore, existing methods are not readily applied to real-world surveillance cameras due to the appearance discontinuity of criminal loiterers. To solve this problem, we abandon the tracking method, instead, propose AntiLoiter to efficiently discover loiterers based on their frequent appearance patterns in longtime multiple surveillance videos. In AntiLoiter, we propose a novel data structure Luigi that indexes data using only similarity value returned by a corresponding function (e.g., face matching). Luigi is adopted to perform efficient similarity search to realize loitering discovery. We conducted extensive experiments on both synthetic and real surveillance videos to evaluate the efficiency and efficacy of our approach. The experimental results show that our system can find out loitering candidates correctly and outperforms existing method by 100 times in terms of runtime.

Acidic electrolyzed water (acidic EW), which is prepared by the electrolysis of an aqueous NaCl solution, has recently become of great importance for disinfection in a variety of fields, including medicine, the food industry and agriculture. In a previous paper we showed that: 1) acidic EW is a mixture of hypocholorite ion, hypochlorous acid and chlorine, depending upon the pH; 2) hypochlorous acid is primarily responsible for disinfection in the case of Escherichia coli K12 and Bacillus subtilis PCI219, both in clean culture media. In practice, however, the use of acidic EW is in many cases severely hampered due to the presence of a variety of non-selective reducing agents. In view of the salient nature of acidic EW, it is therefore strongly urged to establish an optimum way to use acidic EW in a variety of systems. The present paper is the first report on our attempt along this line in order to characterize the nature of the chemical changes that the bactericidal activity of the acidic EW deteriorates in the presence of organic materials, which include amino acids and proteins.

To clarify the four processing stages in the Stroop task (input, decision, response selection, and output), and to examine on which stage or stages the interference occurs, seven undergraduates were used as subjects in a color-naming task with color names, words strongly associated with color, words weakly associated with color, a neutral word, and “xxx” as control stimulus. Color-patch pieces were also used to measure the operant level of reaction time. Main results were as follows: 1. On the congruent trials, the response time was shorter for color names than for the neutral word, control word, and words with weak association. 2. On the incongruent trials, the response time was longer for color names than for the neutral word, control word, and words with weak and strong association. Moreover, the interaction between pre-exposure duration and word conditions was significant; the difference of response time due to word conditions as significant when the pre-exposure duration was short, while it was not significant when the duration was long. 3. The neutral word and the control word gave similar response time, which was longer than that for color-patch pieces. From these results it is concluded that the interference in the Stroop task is most likely to occur on the decision and the output stages.

ヘルスツーリズムとは、医科学的な根拠に基づく健康回復・維持・増進につながる観光である。本研究では、思春期の女性を対象としたヘルスツーリズムを企画し、その中で望ましい食生活を実践できるよう食育を行った。ツアー前に実施した食事調査の結果、脂質の摂取量が目標値である総エネルギーに占める割合30%未満を超えていた。食品群別摂取量では、野菜の摂取量が160gと目標値である350gに達していなかった。また菓子類の摂取量が過剰であった。そこで食事バランスや野菜摂取の重要性を伝える講義を行い、バランスのよい食事をツアーで提供したところ、一食で235gの野菜を使用した料理にもかかわらず、71%の参加者が「野菜の量は気にならず食べることができた」と回答した。ツアー後に行った食事調査の結果、脂質の摂取量は有意に低下し目標値に近づいた。また菓子類の摂取量が少なくなったことから、ヘルスツーリズムでの食育は、食生活改善のための意識を高め、望ましい食生活への実践につながったと思われる。

円形脱毛症病変部の毛包周囲には著明なリンパ球浸潤が観察される。今回の実験を通して、その機序がTh1細胞、Tc1細胞の集合を誘引させるケモカインであるCXCL10が毛包周囲に強く発現し、また円形脱毛症ではそれに対する細胞走化性が亢進していることが明らかになった。急性期のみならず慢性期でもCD8陽性Tc1細胞が持続的に浸潤していた。この走化性を阻害することが治療につながると考えられるが、治療ガイドラインにて推奨されている抗ヒスタミン薬にその阻害効果がみられることがわかった。
