The equipment and techniques associated with magnetic resonance imaging (MRI) have rapidly evolved. The development of 3.0 Tesla MRI has enabled high-resolution imaging of the intracranial vessel wall. High-resolution MRI (HRMRI) can yield excellent visualization of both the arterial wall and lumen, thus facilitating the detection of the primary and secondary features of intracranial arterial dissection. In the present report, we describe the manner in which HRMRI affected our endovascular treatment planning strategy in 2 cases with unruptured intracranial vertebral artery dissection aneurysm. HRMRI provides further information about the vessel wall and the lumen of the unruptured intracranial vertebral artery dissecting aneurysm, which was treated by an endovascular approach in the 2 current cases.

Selection of optimal railway line is taken into consideration include of the purpose of railway, geographical features and facility of management. This study performed opinions of specialists, checking of industrial environment, analysis of bid guideline to select the optimal line and executed AHP method to make quality model and choose weight factors. Therefore, this study executed about six categories which are the efficiency of transportation, facility of planning and construction, economical efficiency, coincidency of planning, the civil appeal and environmental standards, connection with system, and indicated the differences of other method by analyze into specific factors of each categories.

The evolution of mobile communications is inducting several new issues belonging to the system engineering disciplines. this paper tires to underline some of the most important problems staring room the novel requirements and the application characteristics expected for Third Generation Mobile System. Based on these new service peculiarities. the radio resource control and the architectural solutions to be chosen for the Mobile core network are becoming key issues to be investigated for the forthcoming configurations. Particularly. the service acceptance control and the perspective of integration with the IP (internet Protocol) context are of great importance for the definition of the radio control functions and the specification of the switching and nobility control features respectively．The paper presents some basic considerations on the cellular planning issues arising in W-CDMA ( wideband -code division Multiple access) systems. by underlying the most significant innovative elements that are to be introduced in the planning process form the mobile operator viewpoint..

This work is concerned with the motion of propeller driven airplanes, flying at constant velocity on ascending or descending rectilinear trajectories. Its purpose is to provide important features of rectilinear flights that are required for airplane trajectory planning but that cannot be found already published. It presents a method for calculating the amount of fuel used, the restrictions on the trajectory parameters, as inclination and speed, which result from the load factor, the lift coefficient, the positivity and upper boundedness of the power available. It presents a complete discussion of both ascending and descending flights, including gliding. Some original remarks are made about the parameters of gliding. It shows how to construct tables of parameters allowing to identify rapidly flyable trajectories. Sample calculations are shown for the Cessna 182 and a Silver Fox like unmanned aerial vehicle.

The functions of a mobile robot such as obstacle knowledge and collision avoidance for in-door cleaning are necessary features, as has been much studied in the field of industrial automatic guided vehicle or general mobile robot. A mobile robot, in order to avoid collision with obstacles, has to gather data with environment knowledge sensors and recognize environment and the shape of obstacles from the data. In the study, a wall-following algorithm was suggested as a autonomous moving algorithm in which a mobile robot can recognize obstacles in indoor like environment and do cleaning work in effect. The system suggested in the study is for cleaning of nuclear material dusts generated in the process of nuclear fuel manufacturing and decontamination of devices in disorder which is performed in M6 radioactive ray shield hot-cell in IMEF(Irradiated Material Examination Facility) in the Korea Atomic Energy Research Institute.

The purpose of this study was to analyze the preferences for the physical features of senior congregate housing. The survey was conducted to target the elderly households living in senior congregate housing and general elderly households living in the rural. The results of this study were as follows. Showed that housing conditions are more important than environmental conditions, elderly households living in senior congregate housing. Among them was the most important house prices and rents. Also among the external factors such as environmental conditions is the distance to the workplace were very important. So the elderly households living in congregate housing showed that more important considering the economic aspects. Finally, want to be the foundation of sustainable housing policies for rural elderly households.

As the predominant mode of vertical urban development in China, mixed-use complexes provide the optimal case for the research of sustainable and vertical urbanism. This paper reviews three typical mixed-use complexes with various vertical space systems in Shanghai via the combination of field observation, questionnaires and software analysis. It then proceeds to determine which vertical space system is most effective for encouraging sustainable vertical urban development from the perspective of spatial efficiency. Finally, it concludes with an evaluation of the relative capabilities of the design features of a mixed-use complex: to create external dimensional-connections, to create multiple internal connections, and to organize overall composite functions.

The digital network system is one of the most important features in the resent hospital buildings. This study is to lay out a guideline of architectural planning according to the hospitals with digital network system. First, this study develops the concept of hospital building digital network system and reports the survey results of domestic general hospitals for this matter. Required spaces by digital network system in general hospital are classified into two categories. One is equipment room, main equipment room and a telecommunication closet, to accommodate network facilities. The other is the spaces related with medical information, medical archives and the department of radiology, because digital network system makes a change the form and use of information. In result, this study proposes models for each equipment room and raises the possibility of size change of information-spaces.

In modem society, the development of science and industrialization has brought economic growth, and better living environment, improved food life, advanced medicine, and increased span of life have leaded us into the aging society. In the current situation to move toward the aging society, it's needed to prepare housing planning for retirement community in consideration of the physical and psychological and behavioral features of the elderly to raise their quality of life. The purpose of this study was to map out proper housing planning for retirement community in consideration of the physical, psychological and behavioral characteristics of senior citizens, instead of just focusing on comfortable and convenient one.
