지하수 양수정 위치에 따라 대수층 및 하천바닥층의 수리지질학적 특성이 상이하여 양수로 인한 지하수위 저하 및 하천으로의 지하수 유출 감소의 시간적 반응과 그 크기가 공간적으로 다르게 나타난다. 따라서 본 연구에서는 지표수-지하수 통합모형 SWAT-MODFLOW를 죽산천 유역에 적용하여 지하수 양수정 위치에 따른 하천수 감소량을 모의 분석하였다. 대상 유역내에 위치한 전체 지하수 양수정을 고려하여 현재 이용 상태의 하천유량을 모의한 후, 다시 지하수 관정을 모두 제거하여 자연 상태일 때의 하천유량을 산정하여 하천수 감소의 정도를 평가하기 위한 기준유량으로 삼았다. 이어서 하천변 양안 500m 이내 임의 위치에 지하수 양수정을 개별적으로 입력하여 반복 모의를 통해 하천유량을 산정하고 자연 상태의 하천유량과의 차이로부터 하천수 감소량을 산정하였다. 임의 위치 각각에 대해 산정한 하천수 감소량을 크리깅 기법을 통해 공간 보간하여 표출한 결과 양수정 위치에 따라 하천에 미치는 영향의 공간적 편차가 크게 나타났고, 특히 양수 5년후에는 양수량 대비 하천수감소량이 60%를 초과하는 지역이 대부분인 것으로 분석되었다.

This study analyzes the key factors of 3D spatial information in accordance with the establishment of aerial and ground equipment fusion, and the quality improvement solutions are delivered from the preference survey. Furthermore, it investigates the factors affecting the quality of the individual technical elements through the establishment of three-dimensional spatial information. It is for identifying the priority which needs to be improved, and this data will be used to identify the evaluation for factors, the technology development and its application. For this purpose, the presence or absence of equality is judged by the quantitative techniques through the preference survey of the gap between the experts of spatial information and survey and the general users who have experiences on 3D spatial information.

According to many conceptual researches and discourses, development of information-communication technology(ICT) has made great influences upon activities on time and space. But some empirical studies have shown that its influence in the real world is not so great as we may expect In order to avoid these two oppositional views, this paper wants to put interests on socio-spatial relationships or networks, rather than individual phenomena or consciousness, which have been transformed under the influence of ICT. The development of ICT presupposes a creation of information network, and hence the term 'etwork social space' can be used to see its spatial influence, which would be further understood with the theory of actor-network. This paper also suggests that network social space has three strata, that is, 'nstant' 'unctional 'and 'aterial' and that network social space can be emphasized not only as newly emerging social space but also as reconstruction of subjects' identity through his/her participation into information network as its node.

Previous studies for routing In USN (Ubiquitous Sensor Networks) appear to be unreliable due to the dependence on non-spatial data and the lack of map overlay analysis. Multiple spatial parameters and radio propagation modeling techniques were integrated to derive RSSI (Received Signal Strength Indicator) value between route nodes and produce a highly reliable path map. It was possible to identify area-wide patterns of USN route subject to many different Influences (e.g. the specific effects of radio blocking factors such as the visible area, road area, cell duplicated area, and building density), which cannot be acquired by traditional non-spatial modeling. The quantitative evidence concerning the USN route for individual cell as well as entire study area would be utilized as major tools to visualize paths in real-time and to select alternative path when failure or audition of route node occurs.

Although the national government prepares and implements planning for securing various services and facilities based on the needs of welfare centers for leisure of the aged according to the increase of life expectancy. These efforts are still beyond the satisfaction for the needs of the aged. These efforts are only polling on in terms of the increase in quantity, and so therefore there is total lack of high level of welfare facilities for the aged with regard to the consumers' characteristics and behavior attitudes. Under these considerations, this study aims at investigating through indoor space check list, the reality of whether the present welfare centers for the aged are designed with the application of the characteristics and behavior attitudes of the aged to the indoor space. The results of this study are going to be utilized as basic materials for future designs that may consider the behavioral attitudes of the aged and be able to increase their quality of leisure and welfare when building welfare centers for the aged in the future.

In terms of the concept of space in urban planning and design, the modern city approaches from the perspective that all spaces are made up of different places based on identity. In this study, we analyzed disparate image by paying attention to the difference between the individual spaces that form the city. And the physical and behavioral factors that respond to the disparate spatial images are derived through legibility measurement. As a result, the urban space in Busan has disparate images such as closure, openness, dynamic + closure, dynamic + openness, quiet space. The following are the legibility factors that make each image stronger. The elements of closure are high-density and high-rise buildings, residence, work, openness appeared as a factor of water space, walking and viewing. Dynamic & Closure is the element of industrial activity, dynamic & openness is open space, water space, swimming element, quiet space image is green space, walking, stay factor.

This study aims to analyze whether facilities linked to the inside and outside of the station affect the revitalization of commercial spaces inside the station where individual rental stores are clustered. Rent, which can replace sales, was set as the determining factor for revitalization. In addition to the variables related to sales, culture, office work/residential, public institutions, and transportation facilities, the independent variables were the number of daily passengers, which is a location factor of the station, and the product sales business, which accounts for the largest number of industries in the commercial space inside the station. As a result of regression analysis, it was proved that rent has an effect on product sales business, linked sales facilities, transportation facilities, and the number of passengers on board. These results indicate that the formation of sales products that can increase purchasing power and the direction of facility linkage that can increase the inflow population into the station are needed to revitalize commercial spaces in the station. In this study, the establishment of a living-friendly SOC for residents' convenience daily life was suggested as a policy management plan for stations with a high vacancy rate due to reduced vitalization.

지역난방은 한 곳에 집중된 대규모 열원시설에서 경제적으로 생산된 열을 일정한 지역내 아파트, 빌딩, 공공 시설 등에 난방 및 냉방용으로 공급하는 도시 기반시설이다. 또한 지역난방은 개별난방이나 중앙난방의 간헐 난방방식과는 달리 24 시간 연속난방을 하므로써 건강하고 쾌적한 실내온도를 유지시켜 주며, 노후된 보일러 교체비 및 유지 보수가 들지 않고, 난방순환펌프 등 각종 부대시설의 축소로 동력비를 절감할 수 있으며 기존 보일러실을 주민복지 공간으로 활용할 수 있고, 연료탱크와 보조난방기구 등이 필요 없어 재해 발생의 우려가 없다. 본지에서는 한국지역난방공사에서 제공한 자료와 월간 설비기술에 게재된 내용을 요약 정리하여 게재한다.

최근 정보화 시대에 맞추어 교육부에서 제시한 새학교 문화 창조의 일환으로 교육 현장에서는 학습자의 전인적인 특성을 고려해서 평가할 수 있는 수행평가를 실시하고 있다. 하지만, 기존의 학습 평가는 학습자의 학습 수준에 따른 개별화 학습을 하기가 어려워 학습자의 학업 성취도에 따른 학습방향을 제시하기 곤란하고 교사와 학습자의 수업의 질 개선에 어려움이 많다. 따라서, 본 논문에서는 이러한 문제점들을 해결하기 위해서, 학습자가 작성하거나 만든 작품집이나 서류철 등을 이용하여 평가를 실시하는 포트폴리오 평가를 시간과 공간의 제약을 받지 않는 웹기반에서 가능하게 하는 웹 기반 수행평가 시스템을 설계하고 구현한다.
