日本の特殊歯科医療
在来の歯科診療システムでは十分な対応が困難な一群の患者がいる.低年齢の幼児や重度の精神遅滞者には,治療処置への協力は期待できない.脳性麻痺などの肢体不自由者のなかには,安定した姿勢の保持や開口が困難な者がいる.重篤な全身疾患を合併した者や内部障害者では,不用意な治療侵襲は重大な危険を招きかねない.人口の高齢化の進行によって,寝たきり老人の口腔ケアも大きな問題となってきた.スペシャル・ペイシェントと呼ばれるこうした人たちの歯科的健康は,健常な人たち以上に重要な意義がある.そこで近年では小児歯科学,障害者歯科学,高齢者歯科学など,新しい臨床歯科医学の領域が発展しつつある.個人開業医を主体とした第一線医療と病院歯科との有機的連携による地域医療の組織化も,この分野へ取り組みを通じて進行しはじめた.各歯科大学での学部教育にも積極的に取り入れられるようになり,めざましい成果が挙がっている
ExTouch: Spatially-aware embodied manipulation of actuated objects mediated by augmented reality
As domestic robots and smart appliances become increasingly common, they require a simple, universal interface to control their motion. Such an interface must support a simple selection of a connected device, highlight its capabilities and allow for an intuitive manipulation. We propose "exTouch", an embodied spatially-aware approach to touch and control devices through an augmented reality mediated mobile interface. The "exTouch" system extends the users touchscreen interactions into the real world by enabling spatial control over the actuated object. When users touch a device shown in live video on the screen, they can change its position and orientation through multi-touch gestures or by physically moving the screen in relation to the controlled object. We demonstrate that the system can be used for applications such as an omnidirectional vehicle, a drone, and moving furniture for reconfigurable room
Construction and Use Examples of Private Electronic Notary Service in Educational Institutions
People have many documents. For example, a variety of documents are prepared and used in public institutions. As the internet becomes widely available in recent years, paper documents are being replaced with electronic data, which are often distributed in the form of electronic data without being printed out. Similarly, in educational institutions, increasing number of documents are distributed in the form of electronic data. Such data are distributed through various routes and means, and prone to the risk of alteration in the process. Data may be protected against alteration, but it is difficult to completely prevent data alteration in the distribution process. Data can be generated with electronic signature that allows for the identification of data creator and possible alterations by third parties. This method is, however, not valid if the data becomes separated from the electronic signature, making the validation of data creator or data alterations difficult or impossible. In this paper, we describe the invention of a system that, even in cases where data is separated form the electronic signature, enables easy identification of possible data alterations by the electronic signature management. And we describe here an exploratory construction of private electronic notary service in university. We also add a review on the utilization method of private electronic notary service in universities
Improvement of lung function and pulmonary hypertension after pulmonary aneurysm repair: case series
Pulmonary artery aneurysms (PAA) can be complicated with pulmonary arterial hypertension (PAH), causing sudden death due to PA rupture and dissection. Because treatment with PAH-targeted drugs does not always prevent PAA progression, prophylactic surgical repair of the PAA seems a promising alternative. However, although it avoids rupture and dissection of the PAs, additional benefits have not been forthcoming. We therefore present two patients with co-existing PAH and a PAA who underwent surgical repair of the aneurysm. Following the surgery, their lung function and pulmonary hypertension improved. Optimal treatment of PAA remains uncertain, however, with no clear guidelines regarding the best therapeutic approach. This case series provides physicians with reasons to repair PAA surgically in patients with PAH
Second surface: multi-user spatial collaboration system based on augmented reality
An environment for creative collaboration is significant for enhancing human communication and expressive activities, and many researchers have explored different collaborative spatial interaction technologies. However, most of these systems require special equipment and cannot adapt to everyday environment. We introduce Second Surface, a novel multi-user Augmented reality system that fosters a real-time interaction for user-generated contents on top of the physical environment. This interaction takes place in the physical surroundings of everyday objects such as trees or houses. Our system allows users to place three dimensional drawings, texts, and photos relative to such objects and share this expression with any other person who uses the same software at the same spot. Second Surface explores a vision that integrates collaborative virtual spaces into the physical space. Our system can provide an alternate reality that generates a playful and natural interaction in an everyday setup
