The Bell Boeing V-22 Osprey is the tiltrotor aircraft. In 2012, U.S. Marine deployed Osprey at the U.S. Marine Corps' Futenma Air Station in Okinawa prefecture. But, Okinawa residents have opposed the move, citing safety fears. I think Osprey is the ideal aircraft blending the best of helicopters and airplanes, and it will be available for purposes other than military in a near future. This paper attempts to show that Japan should take note about the danger of unmanned aerial vehicle rather than Osprey. First, I explain the position of Osprey in the classification of aircraft and the history of aircraft. Next, I discuss the motivation of rapid development of aircrafts is war. Then, I describe the special features and manipulation of Osprey. Finally, I discuss the safety fears by the deployment of Osprey.

The majority of all ethnic Lao live in northeastern Thailand and their mother tongue is the Lao language. But Thai government prohibited the usage of the name “Lao” and forced to call the Lao language as the Isan language and ethnic Lao as Isan.This study discusses young Lao's linguistic recognition about the Thai language, the Isan language and the Lao language. In 1999, I conducted a survey of young Lao's linguistic recognition on 438 college students in the northeastern Thailand.In this study, I propose the idea of “distance between two languages” to analize the difference of languages. I also apply this idea to three languages used in the northeastern Thailand, that is, the Thai language, the Isan language and the Lao language.The conclusion is that young Lao regard the distance between the Thai language and the Isan language as the inbetween of the same language and different languages. They also regard the distance between the Isan language and the Lao language as the inbetween of the same language and different languages. And they regard the Thai language and the Lao language are different languages.I also came to the conclusion that which language each ethnic group use depends on the difference of the status they are in the northeastern Thailand. Lao is bilingual of the Thai language and the Lao language, and under the state of diglossia. Khmer is trilingual of the Khmer language, the Thai language and the Lao language. Khorat is bilingual of the Khorat language and Thai language.

全日本空手道連盟四大流派の一つである和道流空手において、大塚博紀氏の著書である「空手術之研究」は極めて重要な文献である。 筆者は、和道流空手の修行時に留意すべき点を考察し、「和やかな気持ち」、「脱力による、タメのない敏捷性」、「身体の中心の感覚」の3つの極意を明らかにした「『空手術之研究』から読み解く和道流空手3つの極意」を2010年に執筆した。本稿は、それに続き、空手の形の一つである「ナイハンチ」に関し、新たな気付きを3つの極意に沿って考察し、大塚氏が本部朝基氏のナイハンチに創意を加えた点を明らかにすることで、難解とされる和道流空手の疑問点を解消し、和道流空手技術の継承と発展に寄与することを目的とするものである。
