  • In recent years, LiDAR technology has been becoming more popular and important. Its applications are completely replacing the traditional remote sensing technique. One of these applications is creating Digital City Models in urban areas, which is essential for many others such as disaster management, cartographic mapping, simulation of new buildings, updating and keeping cadastral data. In most of these cases the building outlines is the primary feature of interest. In this paper, a method of extracting building outlines from LiDAR data will be performed.

  • Application examples of computational fluid dynamics (CFD) in the planning stage of high-rise buildings are introduced. First, we introduce examples of applications in the environmental field. The pedestrian wind environment was one of the earliest practical examples of CFD. CFD was also employed to validate the heat island mitigation measures proposed as part of the new construction plan. Second, application examples of wind-force evaluations are introduced. Prediction examples are presented for the peak wind pressure around a complex-shaped building and the wind force evaluation for a base-isolated building. The results prove that the results of the proper execution of CFD are equivalent to those of the wind tunnel experiment. As examples of CFD applications of other issues related to high-rise building planning, we introduce snow accretion on outer walls and high-temperature exhaust from emergency generators. Finally, the future prospects for the use of CFD are discussed.

  • In Korea, the occurrence and risk of similar fires are high, so setting up fire prevention measures through fire case investigation is considered the most basic measure in securing human safety. In particular, calculation of evacuation capacity in evacuation safety design of buildings is the most important factor that directly affects evacuation safety performance. However domestic standards is not consider about occupant characteristics. also the case of domestic, it has the problem that the law is partially applied when the fire safety design of buildings. Therefore, the purpose of this study is to study the current status and related regulations of the life safety code for the application of high fire risk buildings, and to analyze the difference in evacuation time through Case Study.

  • For the past several years, we have built various tools for automatic construction of biopathways to help biological experts, especially in the field of agriculture. We integrated several systems for constructing web applications for analyzing biological pathway information for agricultural species, constructing optimized pathway maps. In addition to building web applications for agricultural pathway information, we developed several stand-alone software tools, which are publicly downloadable under proper license agreements.

  • Nanowires have excellent properties such as high crystallinity, good mechanical properties, quantum confinement effect and high chemical activity, and thus are promising building blocks for many applications. Here we firstly review the fabrication of nanowires by top-down and bottom-up process. We then review nanowires as building blocks for bio applications including bio sensing, cell signaling and cell stimulating. It shows that nanowires are promising for the development of advanced bio technologies that can address ultrahigh sensitivity, and long term cell signaling and stimulating without cell damages.

  • Building Information Modeling (BIM) and modular construction are regarded as important technologies that address several issues faced by the construction industry. However, the application guidelines for BIM in current modular construction projects are insufficient. This paper presents the preliminary work on the analysis of BIM utilization in a modular construction project; a five-point likert scale questionnaire was conducted to assess the necessity of BIM applications by the Necessity Index(NI) of nine categories(U1~U9) across two construction phases (onsite and offsite). The survey results indicate that applications for BIM based quantity takeoff for offsite phase(U4) as well as BIM modeling for module joint details(U8) were deemed to be the most necessary in each phase. The results of this study can be used as detailed guidelines for the integration of BIM in modular construction projects.

  • Bong-amsa Temple is a special temple in the custody of Jogye sect, a branch of Buddhism in Korea. Due to limited public access to this temple, its Geungnakjeon(paradise shrine) has been little known to outside. But it is known that the Geungnakjeon has been not yet explored from academic standpoints in terms of its historical establishment as well as applications, and it would be two-storied wooden pagoda or the like. In order to examine its historical establishment, this study investigated historical records related to Bong-amsa Temple and its intrinsic architectural style. As a result, it was estimated that the building was established around the transitional period ranging from the late Koryo dynasty to the early Joseon dynasty. And it was found that the Geungnakjeon is not the two-storied wooden pagoda, but the unique building including an incidental component called Chayanggan(遮陽間; a sort of stepped penthouse) in Korea. In order to examine its possible applications, this study compared this building with other Buddhist funeral articles in forms similar thereto, such as Buddhist pagoda(僧塔), sarira container(舍利器) and Gamnodo(甘露圖) which depicts Byeoknyeon Daeban(碧蓮臺畔; a palanquin carrying malignant spirit). Then, this study estimated its possible applications on the basis of relevant historical literatures. As a result, it was found that this building was used as Wondang(願堂; a sort of Buddhist prayer house) to wish royal family's going to Nirvana after death, and it was not Confucian-style architecture popularized in the era of Joseon dynasty, but Buddhist-style architecture built widely from the era of Koryo dynasty to the early Joseon dynasty.

  • 본 논문에서는 VIOLA(VIsual Object-oriented Language for Multimedia Applications)이 시각 언어 프레임워크를 제안하다. VIOLA는 웹 응용 프로그램을 자동으로 생성시켜주는 도구이며, 사용자가 정확한 HTML 태그나 CGI 프로그래밍을 모르더라도 자동으로 고수준의 웹 응용 프로그램을 작성할 수 있게 해준다. VIOLA에서는 사용자 접속 설계 부분과 프로그램의 논리 설계 부분 자료흐름 방식에 의해 통합되어 나타난다. 사용자 접속 설계 부분은 직접 조작과 위지윅을 지원하고, 프로그램 논리 설계 부분은 추상화된 아이콘과 사용자 접속과의 연결을 위한 자료흐름 방식을 사용한다. 프로그램 논리는 도구에서 정의된 클래스를 재사용하여 결합함으로써 자동으로 CGI 프로그램으로 생성되어진다. 이러한 방법은 직관적이고 사용하기 쉬워서 초보자라도 쉽고 빠르게 고수준의 웹 응용 프로그램을 생성할 수 있다. 또한 웹 문서의 생성과 저작에 필요한 일련의 기능들이 통합되어 잇다. 생성된 CGI 프로그램은 java로 구현되기 때문에 HTML 문서와 더불어 플랫폼에 독립적이다.

  • Today's commercial high resolution satellite imagery such as IKONOS and QuickBird, offers the potential to extract useful spatial information for geographical database construction and GIS applications. Recognizing this potential use of high resolution satellite imagery, KARI is performing a project for developing Korea multipurpose satellite 3(KOMPSAT-3). Therefore, it is necessary to develop techniques for various GIS applications of KOMPSAT-3, using similar high resolution satellite imagery. As fundamental studies for this purpose, we focused on the extraction of 3D spatial information and the update of existing GIS data from QuickBird imagery. This paper examines the scheme for rectification of high resolution image, and suggests the convenient semi-automatic algorithm for extraction of 3D building information from a single image. The algorithm is based on triangular vector structure that consists of a building bottom point, its corresponding roof point and a shadow end point. The proposed method could increase the number of measurable building, and enhance the digitizing accuracy and the computation efficiency.
