The Braxton-Shore house has been considered as an exemplar of 'space architecture' – an architecture of 'space forms' which R. M. Schindler believed distinguished his work from contemporary functionalists and internationalists. To achieve such' space architecture', Schindler utilized a proportional system of a space reference frame as a mental tool. This paper first outlines the spatial scheme of the Braxton-Shore house, explains Schindler's space reference frame, and finally interprets the prop

This paper presents a study on spatial construction in relation to chants and cathedrals in the medieval period. First, studies on musical space in relation to visual space are surveyed. The gestalt notions of figure and ground are then described. These are used as a basic tool for an analysis of how cathedral arches of the nave were assembled vertically with regard to musical sound. From a formal analysis it is found that the vertical spatial construction of chants and that of naves in medieval

본 논문에서는 bulk형 CdZnTe 감마선 검출기의 제작과 이를 이용한 개인용 선량율계의 제작 및 그 특성에 관하여 기술하였다. 감마선 검출기는 고압 Bridgman법으로 성장된 비저항이 $10^9ohm-cm$ 이상인 단결정을 사용하였으며 electroless deposition법으로 금전극을 형성시켜 사용하였다. 제작된 CdZnTe 검출기는 $^{109}Cd$ 의 22.2 keV 감마선과 $^{241}Am$ 의 59.6 keV 감마선에 대하여 상온에서 각각 4.8keV와 2.2keV의 분해능을 보였다. 또한 이 검출기를 이용하여 개인용 선량율계를 제작하였는데 662keV의 $^{l37}Cs$ 의 감마선에 대하여 1mR/hr에서 10R/hr의 선율에서 변동율 5%이하의 좋은 직진성을 보였고 온도변화 및 조사선율의 각도분포에 대하여도 좋은 응답 특성을 보였다. 【In this paper, we discussed the fabrication and characterization of

Vision-based recognition of the object as a general interface gives us high cost and complicated problem. This research suggests human tracking system by Arduino, and Laser-CdS cell system track wire that pass laser line. In this paper, we review existing literature on application systems of recognition which involves many interdisciplinary studies. We conclude that our method can only reduce cost, but is easy way to trace people's location with the use of wire. Furthermore, we apply several rec

We introduced mathematical economic analysis model for understanding the fairness of charge from VoIP providers for interconnection of access network. In order to set up this model we made four assumptions predictable in the real world. Also we proposed two accounting method that is flat-rate-pricing and usage-based-pricing and tried to propose which method is more desirable to charge for interconnection on the basis of social welfare and activation of market competitiveness. The outcome of this
