The purpose of this study was to provide visual evaluation data in a workstation space when different lighting types were applied. For the performance evaluation, Radiance program was used for simulations, and the mock-up room(15.0x11.6x3m) was used for the actual test. The results of this study were as follows; 1) When the inidirect lighting simulation data using Radiance was compared with the actual data in a small workstation space, there was a 6.5% difference. Therefore, Radiance program was proved to be useful for the evaluation of lighting performance. 2) Higher light levels (higher light ratio (%)) were recorded in the straddled layout and lower light levels (lower light ratio (%)) were recorded in the centered layout condition in most cases. 3) Also, the results show that the indirect luminaires and the straddled layouts provide higher uniformity, whereas the direct luminaires and the centered layouts have lower uniformity.

수치지도를 구성하고 있는 요소 중 주기 데이터는 POI(Point of Interest)라는 원시 데이터의 정확한 위치 및 부가적인 속성정보를 요하는데, 이는 실사와 입력 그리고 여러 단계의 가공 체계를 통하여 구축된다. 본 연구는 구축된 POI로부터 주기 데이터로의 가공 공정에 대해서 수행하였고, 이를 다양한 수치지도 사양에 유연하게 적용하고 수작업을 최소화할 수 있도록 자동배치 알고리즘을 개발하였다. 또한, 본 연구는 그 결과로 시가지도 영역과 시가지도 외 지역으로 나누어 배치전과 배치 후 결과를 지도 레벨별로 분석하고, 연구 수행 중에 도출된 장점들과 향후 보완점에 대해서 언급하고자 한다.

The purpose of this research is to provide the rationality of placement of game objects using the space analysis for game map so that the game designers can find out the proper position for each object in the map. The significance of this research is beyond the limitations of the existing research using Space Syntax theory is confined to the analysis of the behavior of players in the map, this research suggest the method of the efficient placement of game objects in level design step. This paper as the worth of the industry is expected to be able to reduce the repetitive tasks that may occur during game level design steps. Through this, it is also expected by reducing game development period and development costs in accordance with the reasonable placement of game objects.

This study was carried out to suggest improvement plans for problems with the landscape areas of highway service areas. The survey factors were land use, placement of green area and land coverage in terms of spatial and environmental property. Noise and topographic structure in detached green areas were surveyed in terms of impact factor. The status of the planting area around each service area was analysed in regards to planting structure and planting landscape. As a result, the mean of rations of land use were 81.6% building and 18.4% green areas, which were composed of 5.4% landscape area, 9.1% buffer area, etc. Planting areas as usable space accounted for only 0.7%, and the result of noise measurement was different according to the distribution of highway and service area and type of detached green area. The mean of ratio of planting area was 18.4%, which consists of 6.7% landscape planting, 3.4% other green area, 4.6% buffer area, 2.0% buffer and landscape area, 1.1% shade planting and 0.5% landscape and shade planting. Most planting areas aim at landscape appreciation and areas in which visitors can relax and gain recreation were insufficient. The planting structures of service areas were 52.2% canopy layer, 11.8% shrubs and 9.4% canopy and shrub layers, and most of the planting areas were a single layer of green area. Multi-layered planting structures in the landscape and buffer areas were required and a shade planting area was needed to improve amenities as planting canopy layered trees. This study suggested improvement methods for based environments, spatial function and planting function in landscape areas.

본 논문에서는 가구 인테리어를 위해 사전에 제작된 가구의 배치를 인터렉티브하게 시뮬레이션할 수 있도록 3D Visual 시뮬레이터 시스템을 개발하고자 한다. AutoCAD에서 제작된 도면파일(*.dxf)로 가상공간을 구성하고 3D MAX에서 Import된 Object 파일(*.3ds)을 Load하여 사용자가 쉽게 배치할 수 있도록 하는 것에 주안점을 두었다. 구성된 장면에 현실감을 주기 위해 고급 Rendering 기술 구현 또한 목표로 한다. 구축된 공간과 Object에는 텍스쳐 매핑과 Display Edit 기능을 구현하여 최대한 현실적인 시뮬레이터의 기능을 살릴 수 있도록 개발한다.

In order to investigate the effects of foliage plants on the changes of indoor thermal- and hygro- environments, experiments were carried out in two rooms with similar physical factors. Changes of indoor environmental parameters according to the existence of plants, their arrangement methods, and the existence of wrapseal for protecting the loss of water from the pot soil were measured during certain periods in winter and summer season, using Pachira aquatica which is widely used as indoor plant and has higher photosynthetic and traspiration rate than other foliage plants. The data suggested that the existence of plants didn't affect directly on the indoor thermal environment, while relative humidity increased about 3~5%, regardless of season, by putting plants which had volume equivalent to 2.4% of room volume. In summer, there was no difference in increasing effect of relative humidity between parallel arrangement with window and spread arrangement in the room, but in winter the former arrangement was more effective than the later.

Loading zone is necessary to central business district(CBD) due to freight trucks coming into inner city. Currently truck drivers in metropolitan area are forced to illegally park their freight trucks on the roads close to the business facilities because there is no or few loading zones available in the CBD. This situation would bring into traffic congestion and even might block local roads in the CBD. This study reviews the existing improvement plans in city logistics, and examines delivery characteristics related to freight trucks and drivers in Seomyeon, the central downtown of Busan. Also it conducts a location planning for on-street loading/unloading bay using a technical method for arranging loading space. This research estimated the number of parking and stop bays for truck's operation using queueing theory based on truck-service rate and arrival rate, and found locations with the minimum resistance function values for freight movement in arranging on-street loading/unloading bays.

본 논문에서는 공간데이터의 병렬성을 고려한 클러스트 시스템을 제안하였다. 클러스트 시스템의 큰 단점인 다단계 프로토콜 스택에서 오는 메시지 전송 부하를 줄인 VIA(Virtual Interface Architecture)를 기반으로 클러스트 시스템을 구성하고 저장 서버들간에는 공간데이터의 지역성에 기반하여 데이터를 배치하며 저장 서버들 내에서는 공간 데이터의 병렬성을 고려하여 EPR(Enhanced Parallel R-tree)로 데이터를 배치하였다. 위의 클러스트 시스템을 기반으로 적절한 전송 데이터 크기와 전송 횟수를 구하기 위한 실험을 실시하였다.
