プロポフォール麻酔中に低濃度のセボフルランを使用することによって,夢や健忘の出現に変化があるかを検討するために,ASA Iの耳鼻科患者60名を無作為に,プロポフォール+亜酸化窒素(PN)群,セボフルラン+亜酸化窒素(SN)群及びプロポフオール+亜酸化窒素+30分間低濃度セボフルランを30分間隔で投与した(PNs)群の3群(各20例)に分けて比較した.夢の想起率は,PN群で55%,SN群で10%と後者で有意の減少があった.PNs群は45%で,PN群より減少傾向を示した.翌日の健忘については,色に関する回答において,PNs群は他の2群に比べ有意に健忘が増加した.手術室での出来事や覚醒後の出来事についての調査では,PNs群は他の2群に比べ有意に健忘が増加した.プロポフォール+亜酸化窒素麻酔中,低濃度のセボフルランを間歇的に併用すると,夢は減少し健忘は増加して,麻酔の「覚醒の質」の向上を得られることが示唆された.

With the advancement of information and communication technologies, to improve the interoperability between heterogeneous information systems by regularizing the syntax for information exchange is essential to achieve global seamless air traffic management operation. However, the current point-to-point aviation related information exchange among different systems and operators cannot satisfy the requirement for interoperability. The concept of System Wide Information Management (SWIM) has been promoted by the International Civil Aviation Organization (ICAO) to implement interoperability and harmonization in a global operation. In the SWIM environment, all the related stakeholders need to efficiently obtain the necessary ATM data with situational awareness from various information domains. However, this is difficult to realize in the current system, as different data are structured based on different data models. In this study, we construct domain ontologies based on flight, aeronautical, and weather information exchange models. Moreover, for semantic interoperability in the SWIM environment, we develop an upper ontology-based reference ontology that enables common situational awareness of spatiotemporal concepts. Furthermore, we propose a methodology for mapping heterogeneous domain ontologies to the reference ontology with the manual refinement. Finally, we apply the proposed ontologies to a SWIM test system. The applicability and scalability of the proposed ontologies are demonstrated through a case study in the SWIM environment.
