  • The functional change of university forest have led to need more complicated techniques for forest management strategies, and more information about forest and natural environment. Therefore the systematic tools, like the so-called Forest Information System to which apply the techniques of geographic information system, are eagerly required for collecting, editing, managing, analyzing the various data about forest and environment, and for supporting the decision-making process. The digital mapping, which could be a primary step to construct the Forest Information System, was carried out using the many kinds of thematic spatial data referring to the Seongju Experimental Forest of Taegu University. As a result, various digital maps including forest type, soil type and so on were constructed. And then we made an user-interface system to link the attributive data in management plan to the thematic spatial data. This system was regarded as the effective tool capable of the more rapid query, analysis and update of related data for systematic management of university forest. Moreover, it would be a useful tool of decision-making in devising, assessing and operating the plan of forest management and development. But there would be much room for supplementation and improvement to make the more convenient and powerful system for the external demands, therefore more concerns and efforts in collecting, revising and updating the data is continuously required.

  • Some infrastructure these days is usually constructed under the ground for it to not interfere the foot-traffic of pedestrians, and thus, it is difficult to visually confirm the accurate location of the site where the establishments must be buried. These technical difficulties increase the magnitude of the problems that could arise from over-reliance on the experience of the worker or a mere blueprint. Such problems include exposure to flood and collapse. This paper proposes a constructor-oriented visualization system via mobile gadgets in general construction sites with occluded structures. This proposal is consisted with three stages. First, "Stage of detecting manhole and extracting features" detects and extracts the basis point of occluded structures which is unoccluded manhole. Next, "Stage of tracking features" tracks down the extracted features in the previous stage. Lastly, "Stage of visualizing occluded constructions" analyzes and synthesizes the GPS data and 3D objects obtained from mobile gadgets in the previous stages. This proposal implemented ideal method through parallel analysis of manhole detection, feature extraction, and tracking techniques in indoor environment, and confirmed the possibility through occluded water-pipe augmentation in real environment. Also, it offers a practical constructor-oriented environment derived from the augmented 3D results of occluded water-pipings.

  • A grounding system in a large-scale apartment complex consists of a TT grounding system when viewed in each building unit, but the characteristics of TN grounding system appears when viewed in the total ground system function. Therefore, this study examined the characteristics of a grounding system in a large-scale apartment complex using design draft, field measurements and PSCAD/EMTDC modeling. This paper proposes an algorithm for fault analysis depending on the grounding system structure in large-scale apartment complexes considering the connection of the underground culvert as well as a design algorithm for each grounding system considering the contact voltage and step voltage. The simulation results based on the proposed modeling and algorithm confirmed that it is useful for analyzing the characteristics of a grounding system in a large-scale apartment complex.

  • As biodiversity and climate change have become main issues in recent times, the role of the forest ecosystem has been more important and forest conservation has been highlighted. The purpose of this study is to estimate forest area with high conservation values in Gapyung-gun by considering forest ecosystem services. The indicators of biodiversity, climate regulation, and water regulation were selected for assessment in this study. To assess biodiversity, habitat structural features and distribution characteristics of species were analyzed. Climate regulation and water regulation were assessed through analysis of carbon absorption volume and water storage. The result showed that, 50.1% of the forests in Gapyung-gun had high conservation values. The results were verified by comparing them with distribution tendencies of other environmental maps, which represent forest ecological values, and showed similar distribution tendencies. The study was conducted on only Gapyung-gun in Korea; however, the methods used in this study could be utilized for assessment of other areas to identify forests with high conservation values.

  • Control stations managed by national and local governmes are associated with other survey work and constructing geography information and they are important assets in the national level as the positional standard of the country. Since these control points are managed as some type of register and the control points could not be easily updated due to the loss of control stations from construction work or urban development. Therefore, the users could not understand the present situation of the changed control stations. In this background, the aim of this study was to develop control station management system which the managers can use to efficiently maintain control points and to support the usage of the survey control points. For developing this system, we have designed input, update, network, analysis and statistic functions, and have constructed the system using Mapobject as main engine with other languages such as Visual C++ and Visual Basic. The graphic data used in this system are 1/5,000 digital map and digital cadastral map, and the attribute data of each control station are point name, map tile name, longitude and latitude coordinates, TM coordinates, surveying data with the format of year-month-day and control situation photos and so on. In the result of constructing this control station management system, we could achieve integrated management of graphic, attribute and positioning information of each control station.

  • This paper investigates spatial composition and landscape characteristics of the royal tomb(Jangneung in Paju) where the 12th King(Injo) and the Queen(InnYeol) of the Joseon Dynasty are buried. Based on the investigations, the study suggests the management plan of the Royal tomb at the end. The study includes research on ancient literature and the on-site survey to estimate the ancient landscape architecture of the Royal tomb. Thereby, it is intended to provide the basic data for the identification, preservation, and restoration of the landscape architecture. As a result of the study, first, Jangneung is confirmed that it is a typical formal landscape structure of the Royal tomb in the Joseon Dynasty. Second, Ecological resources around the royal tombs are consistent with previous records and current field research. Third, although the Japanese colonial rule damaged much of the Royal tomb, it preserves much of its core facilities. However, the restoration of ancillary facilities is required, and a World Heritage Conservation Management Plan is required that complies with the ICOMOS Charter.

  • The type approval system of the railway safety law, which was enforced in 2014, has been preferentially applied to the field of railway vehicles. The type approval system addresses railway vehicles and railway constituents. Unlike the previous system, it requires serial verification stages divided, in consecutive order, into verification of design compatibility and conformity and type test. These stages are in accord with international certification systems including TSI certification of the European commission. This study has been carried out to find and meet the design requirements for a coupler head, which is a part of the automatic coupler system; requirements were drawn from TSI and technical specifications that are subordinate to the domestic railway approval system. Through this study, it has been found that there exist 34 design requirements to acquire a complete coupler head. Among those requirements, 32 were verified by document inspection and two were able to be verified by performing FEA and gathering range analysis data.

  • Since the Three Dimensional Computer Aided Design(3D CAD) appeared in 1990s, Building Information Modeling(BIM) has got the great issue in the construction project nowadays. BIM is the process of managing and generating building information during life cycle of a construction project. And information can be moved to 3D modeling flexibly in BIM. As a result, a field of estimating has also been doing researches in the calculation of the amount of building materials from 3D modeling. And the Construction Cost Estimating Software which is generally used over the world has been trying to be applied to the Construction project in Korea. But, when we consider the productivity, it is less efficient than the existing way in Korea which use the 2D Drawings when they take off the Quantity. Also, there are lots of difference how to estimate the construction cost. between Korea and the others. Because it is a bit hard to apply the software used in the other countries to the construction project in Korea, people couldn't use it well in the construction project actually. In this study, for developing the appropriate construction cost estimating software rooted in 3D in Korea, we suggest 3D CAD Add-on Program for a Quantity Take-off which can move quantitative information to 3D CAD.
