이동통신과 인터넷 기술의 결합으로 탄생한 무선 인터넷은 휴대의 편리성을 제공하고 있으나 모바일 환경의 제약 사항 때문에 대중적인 인터넷 서비스로는 발전하지 못하고 있다. 무선 환경의 제한 요소 중 협소한 메모리 공간으로 모바일 디바이스에서는 효율적인 자원 관리를 수행하지 못하는 단점을 가지고 있다. 휴대성이 고려되어야 하는 하드웨어 특성상 충분한 메모리 용량을 확보하는 데에는 한계가 있으므로 디바이스 내부의 저장 장치에서 외부의 영역까지 저장 공간을 확대하여 데이터 처리가 수행될 수 있는 모바일 플랫폼 구조로 발전되어야 할 것이다. 본 논문에서는 모바일 디바이스의 내부에서 외부의 서버까지 메모리 공간을 확장하여 데이터 활용을 가능하게 하고 디바이스 내부의 파일을 효율적으로 관리할 수 있는 모바일 에이전트를 제안하며 이를 실현하기 위한 자원 관리시스템(RMS: Resources Management System)을 설계하고 구현하였다. 제안된 RMS를 적용한 디바이스는‘모바일 공간확장’으로 확대된 프로세스 적용이 가능하며 내부 파일을 효과적으로 관리하여 최적의 메모리 공간을 유지하는 효과가 있다.

현재 자동차 대수 당 주차면 수가 충분한 상황이지만, 외부인이 사용할 수 없는 허수 주차 공간이 대부분이다. 이에 본 논문은 불법 주정차의 원인을 비효율적인 주차 공간 활용이라 판단하였다. 아파트 및 상가 주차 공간은 출근 시간대에 여유 주차면 수가 급격히 증가하는데, 이 잉여 공간 중 일부를 외부인에게 공유하여 주차 공간을 최대한 활용할 수 있도록 한다. 애플리케이션 이용자는 원하는 주차장을 예약하고, 출입통제 자동화 시스템의 QR코드 인식을 통해 주차장을 사용할 수 있다. 전체적인 예약 시스템 관리는 웹 브라우저를 이용한다.

This study examines the assessment systems of LEED v4.1, an eco-friendly building evaluation system in the United States, and SITE v2, an assessment system for sustainable outdoor spaces, and then compares and examines them from the perspective ofrelevant laws and institutional guidelines and standards in Korea. The conclusion is as follows. First, the US eco-friendly certification system basically not only establishes an independent evaluation system according to the field of expertise, but also provides a sustainable city and community through response to the climate crisis and the comfort of the external space environment. It can be evaluated that securing the quality of life of healthy and happy city dwellers is the top priority. Second, Korea's Green Building Certification System (G-LEED) was basically based on the American LEED system, but it was judged that there was a fundamental difference. It was judged that there is a limitation in not being able to achieve an integrated approach through the participation of various expert groups and stakeholders, but also in the accumulation of more scientific and reliable data and information through the application of cutting-edge information and communication equipment. Third, in the case of external space in Korea, a sustainable assessment system has not been established, and not only is it dispersed in various legal and institutional guidelines, but also its effectiveness is judged to be very low. Therefore, it is judged that it is urgent to introduce and secure the applicability of SITES v2, a sustainable outdoor space assessment system in the United States. It was judged that the effectiveness should be secured through the upward adjustment of the minimum Ecological Area Ratio.

The data model is a system model which abstracts the spatial and nonspatial fea¬tures of the real world. A system defines through its data model a framework for the inner rep¬resentation of and connections with the outside world. The spatial query language is one of the most efficent framework for defining connection with outside world in the GIS. Existing GIS uses a spatial data model based on relational data model. Therefore, it has some difficulties in data abstraction and representing complex objects through inheritance. In this paper, we pro-pose an object oriented data model-Topological Object Model(TOM). TOM combines object model in ODMG and the planer topological object. Based on this model, we present an object-oriented spatial query language-OQL/Geo. OQL/Geo extends OQL in ODMG and represents TOM effectively. It also provides several operators such as geometric, topological and visible ope-rators. Moreover, it represents with diverse flexivility the request for complex spatial analysis and presentation of query results.

In recent years space planning for modern city has been accomplished through scientific high technique and computer supported collaborative work. Relatively human being is treated as a component of the space or whole building and according to the social structure people tend to prefer private space. The necessity of the open space as an active place is emphasized now because the interaction created between users of the space and the nature, surrounding environment can influence on improving quality of outdoor life and giving the place specific identity. In this paper three ways of analyses of components which compose the open space are studied. Especially through the process of analyses derived from differenet areas, the necessity of communication model in collaborative work is proposed.

Since 1960's Mapo Apartment Housing, the apartment housing has been established as the typical urban housing type, and its design of outdoor spaces being transformed diversely. The purpose of this study is to identify the periodical trend of outdoor space design by analysing the elements of outdoor spaces in the apartment housing estates constructed in Daejon City.

One of the oldest chestnuts in economic geography is this: Cultural and creative industries strongly gather in large cities and this geographic concentration of economic activities leads to regional development. Of course, depending on the circumstances, such a proposition still holds good. But, under the current paradigm shift to knowledge-based economy, it may be open to question. This study aims to investigate financing and knowledge accumulation in the film industry through an alternative framework for explaining their spatial distributions, "formation mechanism of economic space." From the fact that their production organizations are formed on a project basis, project-based financing structure in the investment stage and knowledge accumulation process in the production stage form both axes of it. Film industry as the most mature industry among the cultural and creative industries does not always concentrate in a certain place (industrial agglomeration) or show metropolis-oriented preference. This allows us to reconsider our long brooding theory.

In a typical living space, windows are directly exposed to the external noise environment. The best way to reduce outside noise is to block it from the outside, not the inside. Exterior blinds for blocking sunlight are commercialized in various ways. However, it has not yet been actively utilized in Korea. In the previous study, an experiment was conducted in an accredited laboratory to verify the sound insulation performance of an external motorized blind manufactured for shading. And it was verified that there is a sound insulation performance of 6 dBA compared to the reduction performance of a general window. In this study, we tried to confirm the reduction performance by applying the sound insulation performance of external electric blinds to windows in actual living spaces. In addition, an improvement plan was sought to increase the effective noise reduction performance. As a result of the measurement, the reduction performance of the external motorized blind itself was insufficient at the level of 1 dBA to 3 dBA. However, additional reduction performance of the 2 dBA level was confirmed by filling the gap between the blind slits.
