抄録: It is necessary for medical helicopters to take part in emergency services for highway accidents. Concerned ministries are creating guidelines to include medical helicopter in emergency services. Ambulance services with medical helicopters have been used gradually in Japan. However, for landing on highways, it’s necessary for both police and road management vehicle to be at the accident spot. This causes problems in starting primary treatment early. Our simulation model can show the solution on shorten the starting time of primary treatment which is main purpose of medical helicopters. In addition, cost-benefit analysis by the result of simulation has been done to clarify the effect of death rate reduction. As a result, it becomes clear the great effect of death rate reduction can be done by medical helicopter. If it is possible to conduct traffic regulation by one organization, a bigger effect can be provided. From the viewpoint of cost-benefit balance, the medical helicopter system is a good method.2008-03-30T15:00:00Z渦電流式センサ開発とその圧縮機への応用松村, 憲明http://hdl.handle.net/11133/14262013-10-25T02:29:47Z2008-03-30T15:00:00Zタイトル: 渦電流式センサ開発とその圧縮機への応用

抄録: The prospective impact of this paper lies in its contribution to the development of electrical insulating material technology, based on physical mechanisms that dominate discharge phenomena and electrical insulation performance, and the rationalization of insulation design for power equipment by understanding the current limits of size reduction and increased stress. In addition, technological guidelines on decision-making for life extension and refurbishment of future high-voltage power equipment with various kinds of insulating materials are expected to be developed. Concretely, the following contents are described. Common and divergent points on insulation techniques from material and equipment viewpoints were clarified. Especially, internal stresses of insulating materials for power equipment were compared, where the ratio of ac testing stress to operating stress can be used as an index to show the long-term deterioration or the complexity of insulation structure. The relationship between insulating material and electric charge behavior was investigated and systematically interpreted by introducing a new index. When the charge density was analyzed by the surface resistivity of solid insulators, comparative evaluation of insulation characteristics in different power equipment was possible. The relationship between the deterioration processes of the insulating material and insulation design of power equipment was investigated. Factors and evaluation parameters that will determine the life of equipment were analyzed. Then the differences were attributed to the basic insulation structure. The relationship between harmful partial discharge levels and kind of insulating material was discussed. Cross-equipment comparison was made in terms of preferable sensitivity, present possible sensitivity, decision criteria and the level determined by standard. The concept on insulation design stress for different insulating materials and power equipment was systematically summarized, taking into account various factors that appear explicitly in the procedure of determining the design stress, such as statistical data deviation, long-term deterioration, design margin and so on. And cross-equipment comparison was made from the view point of how severe design to carry out. Then the future prospects of the insulation design were discussed.2008-03-30T15:00:00Z社会的指標を用いたドクターヘリコプターシステム普及のための要因分析二村, 禎晃小池, 則満http://hdl.handle.net/11133/14282013-10-23T16:30:40Z2008-03-30T15:00:00Zタイトル: 社会的指標を用いたドクターヘリコプターシステム普及のための要因分析

抄録: Medical helicopter systems have been in place in Japan from 2001. However, there are only 12 systems operating in 2007. The high cost has been pointed out as the greatest problem for the spread of medical helicopter systems. There have not been any previous studies undertaken about the social factors such as finance, population and so on. This study aim to clarify the relationship between the regional social factors of places where medical helicopter systems do or do not exist. We will apply a logistic-regression analysis and a principal component analysis. As a result of study, the financial coefficient is an important factor for the spread. In addition, 47 prefectures of Japan have been classified into three groups by the regional social factors. We propose co-operative management between neighbor prefectures for systems to spread. Then, the efficient and economical management of medical helicopter systems can be realized.2008-03-30T15:00:00Z
