본 연구는 공원녹지체계를 광의의 개념으로서 오픈스페이스적으로 접근하는 것이라고 설정하고, 그 방법론을 모색하고 실증적으로 대전광역시 도심지역에 적용하였으며, 그 적용 결과에 기초하여 대전광역시 오픈스페이스 네트워크 구축방안을 제시하였다. 연구방법으로 첫째, 대전광역시 구도심을 대상으로 오픈스페이스 네트워크의 적용 가능성을 검토하며, 둘째, 사례지역의 결과를 토대로 대전광역시의 오픈스페이스 유형별 네트워크를 분석하고, 이를 종합함으로써 대전광역시 오픈스페이스네트워크를 구상토록 하였다. 연구결과로서, 활동오픈스페이스 요소인 관공서 및 업무시설들은 자체적으로 또는 건물 전면부에 공개공지가 조성되어 있고, 이들 전면부 공개공지는 보행로(그레이 오픈스페이스)와 연결되어 있으며, 이들 보행로는 결과적으로 대규모 공원이나 하천(그린 및 블루 오픈스페이스)으로 연결되어, 통합하여 하나의 공간체계를 형성한다고 할 수 있다. 따라서 도시 중심부에는 그동안 공원녹지체계의 기본적 요소라고 할 수 있는 공원과 녹지가 상대적으로 적기 때문에, 공원녹지의 추가적 확보가 이루어져야 공원녹지체계의 개선이 진행된다고 볼 수 있다. 도심부에 새로운 공원녹지의 신규조성은 매우 어렵다는 전제하에 도심부에 마치 실핏줄처럼 분포하고 있는 오픈스페이스 네트워크체계로 접근할 경우, 도심부에 보다 건강한 휴식공간체계가 형성될 것이다.

This paper proposes a new framework for control system design, called the data-based control approach or data space approach, in which the input and output data of a dynamical system is directly and solely used to analyze or design a control system without the employment of any mathematical models like transfer functions, state space equations, and kernel representations. Since, in this approach, most of the analysis and design processes are carried out in the domain of the data space, we introduce some notions of geometrical objects, e.g., the openloop and closed-loop data spaces, which serve as the system representations in the data space. In addition, we establish a relationship between the open-loop and closed-loop data spaces that the closed-loop data space is contained in the open-loop data space as one of its subspaces. By using this relationship, we can derive the data-based stabilization condition for a linear time-invariant discrete-time system, which leads to a linear matrix inequality with a rank constraint.

Nowadays the parks in Shanghai tend to develop towards two directions. Small and medimn parks are being gradually transformed from closed management to open management, while large ones emphasize their nature of theme and nature of functions. Simultaneously, the number of large and open public green spaces has been significantly increased. Although the public green space does not adopt the management pattern for parks, there is almost no difference between public green space and ordinary parks so far as the functions and scales are concerned. Due to the fact that there is no obvious boundary between a public park and a public green space, this paper raises a suggestion to coordinate continuously their management and functions so that the distribution of and the connection between the urban green spaces can be more rational and more definite and a sound green network can be formed. Starting from the viewpoint of emphasizing accessibility to green spaces and enhancing the angle of linking green spaces, we aim at transforming a park system to a multifunctional green system, extending the effects and service radius of large green spaces, and strengthening the internal connections with the surrounding areas so that a high-quality green space can be formed with the connection of the green space network.

Recently, the necessity of open spaces is increased greatly in the city. But in many reasons, open spaces are diminishing gradually in the existing cities. It is more difficult to keep that space because of expensive land price, and the interests between the neighbors. To solve this problem, the local governments tries to change the street system more convenient to the pedestrian by adapting no vechile street system during some specific time. In this point of view, the street which include fence of school, house, and apartment can be the open space. Especially, removal of the school fence can be a useful solution providing open spaces to small cities suffering from lack of open spaces. In this researching background, several schools in Wonju were selected in this research, some has already been opened, and others yet. Opinions of students, presidents of these schools, and citizens are surveyed about removal of fence. In the basis of this result, we deduce problems followed by removing the fence, and reflect it in the plan of opening the fence to present the guidance to cross over the functional limitation of the fence and use it as a open space.

This paper presents a data-based stability analysis of a MIMO linear time-invariant discrete-time system, as an extension of the previous results for a SISO system. In the MIMO case, a similar discussion as in the case of a SISO system is also applied, except that an augmented input and output space is considered whose dimension is determined in relation to both the orders of the input and output vectors and the numbers of inputs and outputs. As certain subspaces of the input and output space, both output data space and closed-loop data space are defined, which contain all the behaviors of a system, respectively, with zero input in open-loop and with a control input in closed-loop. Then, we can derive the data-based stability conditions, in which the open-loop stability can be checked by using a data matrix whose column vectors span the output data space and the closed-loop stability can also be checked by using a data matrix whose column vectors span the closed-loop data space.

도시녹지공간의 수목은 체계적이고, 신속한 관리를 함으로써 인간에게 더 많은 혜택을 부여한다. 현재 도시 녹지공간에 있어서의 수목관리의 방법론적인 방안을 고려해 볼 때 수목관리의 유지관리를 위한 자료의 수집과 처리, 첨단 System을 활용한 관리체계가 극히 미흡한 실정이다. 이를 위해서는 먼저 녹지자원 관리를 위한 효율적이고 체계적인 자료의 수집 및 처리와 합리적인 분석과정이 필요하며 그 다음으로 이러한 자료를 토대로 하여 적절한 도시녹지공간에 있어서의 수목관리를 효율적으로 처리할 수 있는 시스템과 그 활용이 필요하다. 이러한 시스템으로 본 연구에서는 최근 여러 분야에서 이용되고 있는 GIS을 이용하여 도시녹지관리모델을 제시하고 이를 통하여 그 효율성을 극대화하였다.

The purpose of this study is to develop means to apply GIS and remote sensing technology to the analysis of Korean urban open spaces. To achieve this objective, a framework of analysis of urban open spaces was developed, and then the framework was applied for the evaluation of the potential and suitability of open spaces of Ansan City, which is a new town developed to accomodate industries relocation from Seoul, Korea, mainly due to their pollution problems. The software used in this study are IDRISI, a grid-based GIS, and KMIPS, a remote sensing analysis system. Both packages are based on IBM PC/AT computers with Microsoft DOS. Landsat MSS and TM data were used for the land use classification, land use change detection, and analysis of transformed vegetation indices. The size of the geographic data base is 110 rows and 150 columns with the spatial resolution of 100m$\times$100m. The framework of analysis includes both quanititative and qualitative analysis of open spaces. The quantitative analysis includes size and distribution of open spaces, urban develpment of open spaces, and the degree of vegree of vegetation removal of the study area. The qualitative analysis includes evaluative criteria for primary productivity of land, park use potential, major visual resources, and urban environmental control. The findings of this study can be summarized as follows. First, the size of builtup areas increased 18.73km$^2$, while the size of forest land decreased 10.86km$^2$ during last ten years. Agricultural lands maintained its size, but shifted toward outside of the city into forest. Second, the potential of open spaces for park use is limited mainly due to their lack of accessibility and connectivity among open spaces, in spite of ample acreage and good site conditions. Third, major landscape elements and historic sites should be connected to the open space system of the city by new accesses and buffers.

This research aimed at measuring Park and Green Satisfaction (PGS) using subjective indicators of 'surface, line and spot' green evaluated by citizens. Also frequency of visits to park and green measured using objective indicators (number of visits) to find the relationship with PGS. A conceptual model of PGS was developed to relate evaluation to satisfaction and finally to utilization of open spaces. A sample of 500 questionnaire survey was employed for Uijeongbu City in Korea. A Structual Equation Modeling (AMOS) techniques was used to test the hypothesized relationship among factors (construct). As a result, first, PGS was explained by three latent factors of 'urban park' (${\gamma}=0.54$), 'linear facilities' (${\gamma}=0.25$), and 'surface green' (${\gamma}=0.15$) respectively. These three exogenous construct was found very useful classification system for open spaces of cities. Second, PGS (${\gamma}=0.34$) was found as a mediating variable to utilization of open spaces and also PGS was closely related to citizens Environmental Quality Satisfaction (EQS), such concept as, 'livability' and 'aesthetic quality'. The more satisfied with park and green the more people use the space. The PGS was an important QOL indicator together with the subjective indicator of 'livability'. Third, jogging and walking trails and bike ways along the river corridor was the most important green facilities contribute to the PGS and EQS. The near the distance (within 500m) the more number of visit to river corridor (green way). The river corridor promote accessibility to nature and other parks.
