Recently, “Nijiku” sports motion theory has been proposed and is being widely disseminated for many types of sports events including association football (soccer). It appears that this theory has some scientific basis for improving performance in sports. However, as the theory did not follow the necessary procedures, to date, its scientific validity has never been examined. This paper was designed to precisely examine the scientific validity of the “Nijiku” sports motion theory in relation to soccer from the viewpoint of science philosophy and biomechanics. Falsifiability is an important concept in science. However, only a few objective data—the ground reaction force of the supporting leg during soccer kicking and the peculiar motion referred to as “unfasten knee” motion—were demonstrated in the related literature with incorrect interpretation, and there were no falsifiable data to prove the existence of “Nijiku” during sports actions. Thus, it has been considered that the “Nijiku” sports motion theory runs contrary to the principle of science. Moreover, there are many misleading descriptions, particularly with regard to the effect of gravity. As a result, it can be considered that the “Nijiku” sports motion theory is classified as a “pseudoscience” labeled inaccurately or misleadingly portrayed as science. Scientific counterarguments to stimulate debate on these matters by the proponent and/or supporters are expected.

<p>The standard treatment for stroke risk patients with non-valvular atrial fibrillation (NVAF) is the use of oral anticoagulants (OACs). However, a substantial number of patients have relative or absolute contraindications to OACs due to concerns of major bleeding risk and other adverse effects while using oral anticoagulation therapy. Recently, occurrences of exclusion of the left atrial appendage (LAA) in patients with contraindication to anticoagulation therapy are widely expanding worldwide, causing major contentious discussions. The LAA is the commonest place of thrombus formation; therefore, the concept of LAA occlusion in reducing stroke and other embolic events in NVAF patients is very important. The current understanding of the available evidence on efficacy and safety of LAA closure (LAAC) with the Watchman device in patients contraindicated to OACs is the major aim of this focused review. After reviewing a significant body of literature, a world experience with no randomized trials, it is suggested that Watchman device implantation is effective and safe in high-risk patients with NVAF contraindicated to OACs therapy.</p>

Ishigaki Island is located in Okinawa prefecture. A few decades ago, Okinawa prefecture was independent country from Japan as Ryukyu Kingdom. Ryukyu was established in the fifteenth century. The emperor of Ryukyu Kingdom visited the king of Ch’ing of China and took an oath to subordinate to him. China was the Suzerain of Ryukyu Kingdom. The king of Ryukyu pay a tribute to the Edo Shogun, Ieyasu TOUGAWA, too. TOUGAWA Shogun (General TOKUGAWA) forced Satsuma feudal clan, feudal lord Shimazu, to attack the Ryukyu kingdom, and to force obedience to Tokugawa Shogun. This is why Ryukyu king took a long journey to Edo as a ceremonial tribute paid to the Tokugawa court. The Sino-Japanese War (1894-1895) changed the fate of Ryukyu conclusively. After the war, Japan reigned the Ryukyu kingdom. Japanese government in Meiji era incorporated the Ryukyu kingdom into Japanese country, which was newly called Okinawa prefecture. In nineteenth century, Japanese Army invaded the northern part of Asia, and expanded the Japanese colonies. In the middle of the nineteenth century, Japanese army power were declined, and defeated everywhere in the whole area of East Asia. Allied force, especially American troops concentrated their attack to the main land of Japan. Japanese government and Army had no equipment to protect the main land against the Allies. Okinawa was the first battle field, and ultimate most important protect wall for the government to keep time for defending Japanese mainland. Unconditional surrender of Japan, Okinawa had been conquered by Allies, America, till 1972. Japanese government realized the return of Okinawa prefecture to Japan. After the World War II, people of the islands and demobilization soldier suffered economic distress and difficulty of everyday life. Development of the “Yaeyama Islands” and pioneer emigrants began at that time. In spite of destruction by the war, traditional culture of Ryukyu are now inherited, succeeded and enriched by the youth. Though the life of the youth in islands aren’t so easy, they enjoy their everyday life and make efforts to create attractive activities. Now, the problem of the territory of Senkaku Islnds has been occurred between Japan and China. It is inevitable for us to know the historical processes profoundly, if we want to understand deeply the local reality, today.

【目的】我々は2009年より世界COPDデーに合わせて,医療従事者による肺年齢測定(以下,肺機能測定)とその結果説明,禁煙指導,吸入指導,栄養指導,呼吸リハビリ体験などを組み込んだCOPDの啓発活動を行ってきた。そして,2013年の世界COPDデーにおいて,「肺機能測定に参加した人数世界一」という世界記録に挑戦するイベントを企画し,1日の測定人数でギネス世界記録<sup>TM</sup>を大幅に更新した。肺機能測定は測定時の実施環境を整えることが重要であり,同日に同一地域で測定された本結果は非常に精度が高く,信頼性の高いものと考えられる。そこで,COPD問診票であるIPAG質問票(以下,IPAG)と肺機能測定より得られた結果を分析し,大規模なCOPD実態調査を行ったのでここに報告する。【方法】対象はイベントに参加した者のうち,肺機能測定を希望した1020名とした。調査内容は肺機能測定とIPAG,喫煙の有無の計3項目とした。分析対象は,40歳以上で肺機能測定およびIPAGともに記録の不備が無かった714名とした。肺機能測定では1秒率70%未満を気流閉塞と定義し,IPAGでは特異度の高い20点以上をカットオフ値とした。更に,肺機能測定で気流閉塞を認め,IPAGで20点以上であった者を「COPD疑い」と定義し,喫煙率についても算出した。【結果と考察】今回,肺機能測定とIPAGの結果を分析したところ,「COPD疑い」とされた者は13.2%であった。そのうち,継続喫煙者が14.9%,既喫煙者が46.8%であり,合わせると61.7%にものぼり,喫煙とCOPDの発症が深く関与していることを裏付けていた。しかしながら,本調査では「COPD疑い」とされた者の中で非喫煙者が38.3%と非常に高く,これまで考えられていた以上に受動喫煙を含む環境因子が大きな影響を及ぼす可能性があることが示唆された。
