Using information mapping methodology we will discover which of the multitude of information sources, services and systems used by corporation are actually resources and which are less important, redundant, or unnecessary. The discovery process of information resources will illuminate problems and opportunities related corporation's strengths and weeknesses in information quality, accessibility, performance, use, and effectiveness.

소프트웨어 설계 프로세스는 일반적으로 두 가지 활동을 통해 수행되는 데, 한 가지는 소프트웨어 시스템을 적절한 크기의 기능모듈로 분해해 나가는 것이며, 다른 한가지는 분해된 모듈을 구조적 패턴 위에 매핑 하는 것이다 본 논문의 관점은 분해된 기능모듈을 매핑 하는 구조적 패턴을 개발하는 데 있으며, 이러한 패턴들이 체계화하여 기능모듈을 구조화하는 작업을 보다 효율적으로 추진하여 높은 품질의 소프트웨어를 효율적으로 개발할 수 있도록 하고자 한다.

임베디드 시스템을 위한 가상기계 기술은 모바일 디바이스와 디지털 TV등의 다운로드 솔루션에 꼭 필요한 소프트웨어 기술이다. 현재 EVM(Embedded Virtual Machine)이라 명명되어진 임베디드 시스템을 위한 가상기계에 대한 연구가 진행 중이며, EVM의 중간 언어로 SIL(Standard Intermediate Language)이 설계되었다. 본 논문에서는 임베디드 시스템을 위한 가상기계의 표준 중간 언어로서 SIL의 완벽성을 증명한다. 기존에 이미 널리 사용되고 있는 가상기계 코드를 SIL 카테고리에 매핑시킴으로써 구조적으로 SIL의 완벽성을 증명한다. SIL은 표준 중간 언어로서의 요구 사항을 갖추고 있으며 6개의 메인 카테고리와 16개의 서브 카테고리로 나누어진다. Oolong과 .NET IL등 기존의 가상기계 코드들의 카테고리는 SIL카테고리에 매핑된다.

The mobile mapping system first introduced at Ohio State University in 1991 is being developed in various forms as sensor technology develops. The mobile mapping system can acquire geospatial information around amoving object quickly using the information gathered using the position and attitude information of the moving object and the data from various sensors. The mobile mapping system can rapidly acquire large amounts of Geospatial information and MMS provides maximum productivity in the same measurement methods as existing GNSS and total stations. Currently, a variety of systems are being launched, mainly by foreign companies, and they are applied to the construction of geospatial information. On the other hand, the application of domestic technology development or production is insufficient. This paper provides basic data for the introduction of a mobile mapping system to geospatial information related business by conducting the status survey and feature analysis of a commercialized system focusing on the ground-based mobile mapping system. The research identified the current status and characteristics of high-priced, low-priced, indoor, and handheld mobile mapping systems based on vehicles and suggest that the recent system development trends are moving toward lowering the unit prices. The mobile mapping system is currently being developed as a platform for the application of geospatial information construction and the launch of low-cost models. The development of data processing technologies, such as automatic matching and the launch of low-cost models, are forming a basis for the application of mobile mapping systems in the field of geospatial information construction.

Recently, BIM has become mandatory in the construction field, research on various use cases is increasing. In particular, when virtual reality technology, one of the core technologies of the 4th industrial revolution, and BIM are combined, it can be used in various fields such as preliminary design review and construction simulation. Until now, however, virtual reality grafting technology is only used as a simple prototype or as a model house. Also, it is difficult to activate virtual construction because it is expensive to produce high-quality virtual reality contents. Therefore, in this paper, in order to increase the utilization and quality of the virtual construction field, a study was conducted to shorten the material mapping time, which takes a lot of time when producing virtual reality contents using BIM. To this end, object properties were assigned to enable material mapping in the BIM model, and materials most used in the construction field were configured, and automated material function development and final tests were conducted that automatically map properties and materials. For the test, 10 models were used and the test was repeated three times, and the productivity improvement of about 50.16% was finally achieved. In the future, we plan to conduct research on physical data weight reduction based on the advanced material mapping automation function and the large-capacity BIM model.

In this paper, we studied projection mapping, which is being utilized as a digital canvas beyond space and time for theme parks, mega events, and exhibition performances. Since the existing projection technology used for fixed objects has the limitation that it is difficult to map moving objects in terms of utilization, it is urgent to develop a technology that can track and map moving objects and a real-time dynamic projection mapping system based on dynamically moving objects so that it can respond to various markets such as performances, exhibitions, and theme parks. In this paper, we propose a system that can track real-time objects in real time and eliminate the delay phenomenon by developing hardware and performing high-speed image processing. Specifically, we develop a real-time object image analysis and projection focusing control unit, an integrated operating system for a real-time object tracking system, and an image processing library for projection mapping. This research is expected to have a wide range of applications in the technology-intensive industry that utilizes real-time vision machine-based detection technology, as well as in the industry where cutting-edge science and technology are converged and produced.

In this paper we present INCUI, a user interface based on natural view of physical user interface of target devices and services in pervasive computing environment. We present a concept of Intuitively Natural and Consistent User Interface (INCUI) consisted of an image of physical user interface and a description XML file. Then we elaborate how INCUI template can be used to consistently map user interface components structurally and visually. We describe the process of INCUI mapping and a novel mapping method selection architecture based on domain size, types of source and target INCUI. Especially we developed and applied an extended LCS-based algorithm using prefix/postfix/synonym for similarity calculation.

According as the users can connect to remote hosts at anytime by using internet, the demand of non-stop system is increased. Also, the research about on-line adding/deleting disks and hosts are progressed. This paper suggests that the method of reducing additional operation when we add disks to the stripping system. That method can fast mapping like equation based mapping method because of using so-called SZIT(Striping Zone Information Table) and equations. And that method can reduce the relocation overhead in striping system at adding disks.

Recently many studies has been conducted for interactive game to contents immersion through visual stimuli. Among them, Multi-Plane Image tech is suitable for projecting video in wide views, but it is difficult to perform calibration and mapping tasks for viewing separately. In this paper, we developed a calibration mapping applies to the field archery game space in the form of CAVE. As a result, we maintained the resolution confirmed the space through the video without distortion and expect to be applicable to the fields requiring presence, such as training contents.

Research on mapping levees is an important task for assessing levee stability. The drone imagery acquired in river basins is useful for generating real-time levee maps. This research proposes a robust methodology for mapping levees in river basins using the drone imagery. In the first step, the multiple imagery taken in the test bed was acquired by the drone. Then, the orthorectified image and DEM (Digital Elevation Model) were generated by the photogrammetry and image processing process. Finally, the significant features on levee surfaces such as levee tops, levee lines, levee slopes, eroded areas were detected from the generated DEM and orthorectified image by manual labors and automatic methods. In future research, the automatic procedure for identifying the significant levee features from the drone imagery would be proposed.
