Along with the development in cutting-edge digital technology, the street space is also being changed. Mobile telecommunication units and internet give a big change in a human being's lifestyle. And the ubiquitous computing is proceeding with expanding its application range from the indoor space to the street space. As the street furniture is the convenient facility that allows a human being's life in street space to be abundant, it is getting advanced. First of all, in terms of such phenomenon, this study analyzed the cases of a research on application of street space and the actual condition of a change in the number of individuals for the street furniture, through a literature research of ubiquitous. Also, it researched into the realities of using the street furniture of the walking-desired streets at Daehac-ro and Hongdae district, where are two representative places related to digital generation. The next was carried out FGI (Focus Group Interview) with users of the street space in front of Hongik University and managers of the street furniture, and was researched into the use & management behavior, and recognition level on the street furniture. Thus, the key elements were extracted such as interchange of information for cultural activities, automation for interaction variability in function. Finally the core elements for future vision of street furniture in this digital era were extracted in 3I, namely, Information, Intellectualization, and Integration. This is considered to be applied to the establishment of direction in the process of high-tech digitalization in street furniture related to information hereafter.

Purpose of this paper is to research about new building type of Korean library and suggest the design of Library which based on the building type changes. This research is based on the idea that change of building type could be derived from Architects' designs. So, we analyzed space programs of Gunpo Library competition, redefined the space programs and suggested the direction of building type changes with program changes through design processes. The conclusions of this research are follows; first, we suggested new zoning system in library building design that is consisted of three separate building based on each building's own functions. Second, new zoning and library design would be helpful to making plan about library building competition. The method that we tried at this projec is useful to other complex building designs which have necessities to redefine building type.

Territory is determined by physical elements that provide the occupants an obvious boundary in a space. The creation of boundary is a interpersonal process by which a person or group regulates interactions with others. The perception of territory needs boundary regulations that mean the composition of horizontal and vertical elements in architectural space. The perception of territory can be defined as perceptual reaction considering not only visual perception on the physical elements in the architectural space and also various kinds of social activity in architectural environment. To achiever territory in architectural space, visible and invisible boundary regulation should be need. It means that territorial boundary regulation needs visual and audial boundary regulation as well as spatial boundary regulation.

Water plays significant roles in constructing architectural structures. This is because a comfortable human life is impossible without proper distribution of water. Here the notion of water space is introduced in the field of the modern architecture. This study examines the typological variations of water space in the outdoor space of architectural structures and concludes the contents discussed. Unlike the traditional architecture, the modern architecture takes the types of water into account. And in the modern architecture the multiple considerations of water space are being made for the public, not for the specific customers.

Presents age is diversified in all genres by fast development of information and digital, and expression of fixing is not. Architecture and interior space design is showing new paradigm through dematerializing, ex-formal, nonlinear. Glass material is expressing by various technique in space and outer skin to introduction of digital media and a high-tech technology. Expressive characteristics and Techniques of this glass material are showing form of homogenized life in this age, simulated life. Therefore, this study does theoretical investigation through dematerializing of glass material, and analyzes works after 2000. Wish to understand stream of indoor design of present age after analyzes expression special quality and technique of glass material that reflect age and make a study of symbolic expression characteristic.

A projection-based active information display system was proposed. The proposed system is based on Intelligent Space and a steerable projector mounted mobile robot which is called Ubiquitous Display (UD). In order to transfer visual information for a human in the Intelligent Space, the UD projects a certain shape of an image with a fixed size. Due to redundancy of degree of freedom (DOF), there are lots of situations to project a same shape and size of the image on a surface. In this paper, we describe a method to determine a goal posture of the UD. Here, the goal posture is the most efficient position and orientation of the UD so as to project visual information and it is determined by the Intelligent Space. To verify the proposed method, simulation and demonstration are carried out.

본 연구는 기본적으로 현대 디지털 사회에서의 게임의 공간 문제를 장소론적으로 해석하려는 목적을 갖고 있다. 디지털 게임에서의 공간과 장소성은 인류학적으로 보는 관점과는 어떠한 공통점과 차이점이 있는지를 탐구하여 게임의 비장소의 공간들이 어떻게 구현되고 장소적 특성을 보이고 있는지를 살펴봄으로써 장소론적 입장에서 게임공간을 연구하였다. 디지털 게임공간의 장소성에 관한 연구는 디지털게임을 이해하는데 있어 기존의 '매체 지향적 논의'들과 '서사중심'의 파편적인 논의를 통합하는 계기를 제공하고 다양한 방향으로서의 연구 가능성을 제시할 수 있으리라 본다.

This paper presents a servo control scheme for the surface-mounted permanent-magnet synchronous motor(SPMSM) which essentially uses vector control algorithm. The control system is composed of the PI controller for speed control and the current controller using space voltage vector PWM technique. The high-speed calculation and processing for vector control is carried out by TMS320C31 digital signal processor and IGBT module. The proposed scheme is verified through digital simulations and experiments for 2.2kW SPMSM and shows good dynamic performance.
