Visual analytic for intangible cultural heritage has recently developed in China. Using advanced interactive visualization tools experts can observe data distribution trends and explore the implicit relationships among data within a short time. It can enhance human cognitive and analytical abilities and improve the scientific preservation of intangible cultural heritage. To support this research topic, we have reviewed recent visualization works on intangible cultural heritage in China. We divide these works into three types: text visualization, multi-dimensional visualization, and geographical visualization. Each type is illustrated by several representative works. New development trends in this area are also discussed.

본 논문은 LonWorks 네트워크를 이용한 원격 홈오토메이션 시스템에 대해서 설명한다. 최근 홈네트워킹 개념의 확산에 따라 다양한 정보가전 기술의 발전이 가속화 되고 있다. 또한, 다양한 정보 가전 기기를 연동하기 위한 다양한 매체(IEEE1394, USB, PLC, TP, IRDA, BLUETOOTH 등)가 제시되고 있고 이를 제어하기 위한 미들웨어(Jini, Havi, LonWorks 등)가 거론되고 있다. 이러한 환경에서 가능한 서비스를 미리 살펴보고 이를 구성하기 위한 기본적인 요소 기술의 필요성을 살펴본다. 본 논문에서 설계한 원격 홈오토메이션 시스템은 제어 미들웨어에서 표준이 되고 있는 LonWorks를 이용하여 인터넷에서 홈내부의 디바이스를 모니터링 가능하도록 구축하였다.

The purpose of this paper was to present the method of progress efficiency of morphosyntaxical analyzer for French information processing in the view of multilingual information processing. This study indicated that he method prohibit the additional useless word type by decomposing word type by decomposing works which were created by morphological amalgamation. Findings also suggested the need of preprocessing in order to decrease the overload of morphosyntaxical analysis algorithm. In addition, general rules were proposed to divide word form and to decompose complex sentence.

In this paper, we implemented the voxel coloring method to reconstruct 3D object from synthetic input Images. Then compare the result between using standard voxel coloring and using coarse-to-fine method. We compared using different voxel space site to see the difference of time processing and the result of 3D object. Photorealistic 3D object reconstruction is a challenging problem in computer graphics. Vexel coloring considered the reconstruction problem as a color reconstruction problem, instead of shape reconstruction problem. This method works by discretizing scene space into yokels, then traversed and colored those in special order. Also there is an extension of voxel coloring method far decreasing the amount of processing time called coarse-to-fine method. This. method works using low resolution instead of high resolution as input and after processing finish, apply some kind of search strategy.

윈도우즈, 리눅스 등 시장 점유율이 높은 운영체제의 경우에는 다양한 디버깅 도구들로 인해 개발 효율성이 향상된다. 반면 VxWorks 운영체제의 경우에는 실시간성이 요구되는 임베디드 환경에서 제한적으로 사용되어 디버깅 도구 부족 등 개발 효율성 측면에서 여러 제약사항들이 존재한다. 다양한 소프트웨어 오류 가운데 임베디드 환경의 제약으로 인한 대표적인 하드웨어 리소스인 CPU, 메모리와 관련된 디버깅 방안에 관해 소개하고 디버깅 효율성을 개선하고자 한다.

Information superhighway and improvement of computing power result in increase of the requirements for distributed multimedia applications. But, developer of applications needs much time and efforts because of the difficulties of development, enhancement and maintenance of distributed applications. To solve this problem, CORBA is used widely. But, the definitions of CORBA services are required for the brief developments of distributed multimedia applications. Especially, collaboration service is required because multiple users use distributed multimedia service. Collaboration service manages user and group information of applications and makes the interoperability between of multi users. In this paper, we designed collaboration service for CORBA based distributed multimedia applications. Collaboration service is able to maintain group information and to present the ability for collaborative works between of multi users. Application developers can develop the applications easily because the ability of collaborative works is offered by collaboration service.

LonWorks 을 이용해 홈 네트워크를 구성할 수 있다. 기존에는 하나의 노드가 되는 조명, 딤머(dimmer), 스위치에 해당하는 디바이스를 중앙 집중식으로 제어할 수 있는 컨트롤러가 개발되어 왔다. 본 논문에서 제시하는 컨트롤러는 스위치와 조명사이에 데이터를 처리하는 중개자의 역할을 하는 중요한 오브젝트이다. 본 논문에서는 이 기술의 핵심인 LonTalk 프로토콜을 설명하고 네트워크에 구성되는 컨트롤러에 대해 주소 지정방식을 이용하여, 여러 개의 조명을 연결될 수 있도록 네트워크 변수 타입을 제시하였다. 뉴런(Neuron)C 로 펌웨어(Firmware)를 구성하여 결과값을 얻을 수 있었고, LonWorks의 어플리케이션인 LNS(Lonworks Network Service)를 통해 플러그 인 부분까지 구현하여 해당 결과값을 확인할 수 있었다.

Software maintenance is one of the major activities of the software development life cycle. Due to the time and cost constraint it is not possible to perform exhaustive regression testing. Thus, there is a need for a technique that selects and prioritizes the effective and important test cases so that the testing effort is reduced. In an analogous study we have proposed a new variable based algorithm that works on variables using the hybrid technique. However, in the real world the programs consist of multiple modules. Hence, in this work we propose a regression testing algorithm that works on interprocedural programs. In order to validate and analyze this technique we have used various programs. The result shows that the performance and accuracy of this technique is very high.

A simulator in Android is developed for Qualcomm Augmented Reality (QCAR) software development kit (SDK). The main purpose is to replace the testing of application on actual Android device. Bugs in the application can be found easily when testing is done in the simulator (with support of Android emulator) before the testing on real device. The simulator does not require a camera in testing augmented reality application. Works included study on QCAR SDK's behavior is done to ensure that the simulator performs similar to the SDK. Description on how would the simulator works with QCAR SDK is included in the paper.
