Background: The effect of natural disasters on secondary sex ratio (SSR) and perinatal outcomes has been suggested. This study aimed to examine effects of the Great East Japan Earthquake on perinatal outcomes using vital statistics of Japan.Methods: Birth registration data from vital statistics of Japan between March 2010 and March 2012 were used. Pregnant women who experienced the earthquake were categorized according to their gestational period as of March 11, 2011, as follows: gestational weeks 4–11, 12–19, 20–27, and 28–36 (2011 group). Similarly, pregnant women who did not experience the earthquake were categorized according to their gestational period as of March 11, 2010 and used as controls (2010 group). We also categorized prefectures as “extremely affected”, “moderately affected”, and “slightly or unaffected” regions. SSR, birth weight, and gestational period were compared between both groups.Results: The number of singleton births was 688 479 in the 2010 group and 679 131 in the 2011 group. In the extremely affected region, the SSR among women at 4–11 weeks of gestation was significantly lower in the 2011 group compared with the 2010 group (49.8% vs 52.1%, P = 0.009). In the extremely affected region, children born to women who experienced the earthquake at 28–36 weeks of gestation had significantly lower birth weights.Conclusions: The SSR declined among women who experienced the earthquake during early pregnancy, particularly in the extremely affected region. However, no apparent negative effect of the earthquake on perinatal outcomes was observed, although birth weight of infants who were born to women who experienced the earthquake at 28–36 weeks of gestation were lower.

Underwater propulsion that leaves little traceable wake structure while producing high levels of thrust is a highly desired goal. A potential biological model is the California sea lion, a highly maneuverable aquatic mammal that produces thrust primarily with its foreflippers without a characteristic flapping frequency. In an effort to mimic the sea lion flipper, a flipper from a sea lion carcass has been scanned using several non invasive methods with the goal of manufacturing a robotic flipper with identical geometry. The scanning methods are hereby compared for overall quality, accuracy, and level of detail captured.

By analyzing a TV program on the vulnerability of the Y chromosome and the possible extinct of human beings, it is shown that the program took a scientific evidence (the vulnerability of the Y chromosome) and put it in a context different from the original and academic one. The extinct of humans is not a subject of the normal science and is a type of trans-science question. Among many entertainment tools, this type of deconstruction is useful to make the program quickly understandable for non-experts. It is quite possible that the deconstruction reveals the context owned by the society. This can be unavoidable and the academy should not have right nor obligation to stop it. On the other hand, the scientists should be aware of the deconstruction mechanism of the media and the society and try to coexist with it as a different culture.

The microbial communities transported by Asian desert dust (KOSA) events have attracted much attention as bioaerosols, because the transported microorganisms are thought to influence the downwind ecosystems in Japan. In particular, halotolerant bacteria which are known to be tolerant to atmospheric environmental stresses were investigated for clarifying the long-range transport of microorganisms by KOSA. Bioaerosol samples were collected at high altitudes within the KOSA source area (Dunhuang City, China) and the KOSA arrival area (Suzu City, Japan). The microorganisms in bioaerosol samples grew in media containing up to 15 % NaCl, suggesting that bacteria tolerant to high salinities would remain viable in the atmosphere. The PCR-DGGE (Denaturing gradient gel electrophoresis) analysis using 16S rRNA genes sequences revealed that the halobacterial communities in bioaerosol samples belonged to the members of the genera Bacillus and Staphylococcus and that some bacterial species belonging to Bacillus subtilis group were similar among the samples of both cities. Moreover, some sequences of B. subtilis group were found to be identical for the species collected at high altitudes and on the ground surfaces. This suggests that active mixing of the boundary layer transports viable halotolerant bacteria up to the free atmosphere at the KOSA source area, while down to the ground surface at the KOSA arrival areas.

近年, ディジタル技術の高度化に伴い情報の高密度化が進んできたが, アナログ技術の観点からもディジタル技術の進歩に見合う高精度化が要求されると考える.本研究では, スピーカボックス, CDプレーヤ, アンプなどステレオ再生機器の機械的振動が, 再生音の音質や音像表現にどのように影響するかの関係解明を試みる.具体的には, 機械的振動の対策により機器振動の高調波成分の低減が観測され, 放射音や電気信号に含まれる高調波歪成分の低減にも寄与していることを確認している.さらに, 高調波歪の低減により再生音がどのように改善されるかを, 音質と音像表現力(定位と明確さ)についての試聴実験により検証している.
