As recent multilateral collaboration design system has been advanced, BIM based data exchange is a key factor for successful next generation building project. Even though many studies have been trying to set up a data compatibility system for collaboration, There are still a lot of problem in data exchange between design and engineering phase. Therefore, In this study, we analysis causes of problem for information exchange and suggest a IFC based Information exchange framework for improving BIM based design collaboration environment. In order to find out problems that hinder establishment of advanced open BIM information exchange, proper analysis about transition of process from current and to-be BIM based design collaboration process is important, at first. From analysis of main obstacles to information exchange, this research suggests solution plan using open API and IFC based BIM collaboration supporting system. The suggested open API solution named Integrity feedback system perform a role making up for weak point derived from IFC based data exchange. And main system suggestion about framework for IFC based information exchange reflect technological system support, requirement of function for collaboration including API/BCF plug-in.

최근 정보기술의 급속한 발달 따라 사회 전반적인 체제의 정보화 현상으로 개인이나 조직의 활동이 정보와 밀접한 관련성을 가지게 됨으로써 이용자의 정보 수요에 적합한 정보원을 제공하는 매개자의 기능을 수행하고 있는 정보전문가의 역할이 한층 더 부각되고 있다. 이러한 영향이 도서관이나 정보센터의 모든 활동에 파급됨에 따라 정보를 수집, 가공, 분석. 저장 및 전달을 담당하고 있는 정보 전문가는 종래의 문헌중심봉사(book-based service)에서 정보중심봉사(information-based service) 형태로 역할 변환이 요구되고 있다. 특히 주제전문 봉사를 담당하고 있는 사서나 정보전문가는 이러한 정보기술의 파급효과를 더욱 실감하고 있는 실정이다. 이러한 상황에서 본 연구는 첫째, 정보기술의 발달이 사회과학 분야의 정보봉사에 미치는 영향과 효과를 살펴보고. 둘째로 사회과학 분야 정보제공을 위한 정보시스템의 특성 분석과 정보기술을 매체로 이용하고 있는 정보전문가의 정보기술에 대한 인식을 실증적으로 분석하고 있으며, 마지막으로 정보사회에서 다양한 정보제공을 담당할 사회과학 정보전문가의 새로운 역할 모델을 제시하고 있다. 사회과학 분야의 정보제공을 효율적으로 수행하기 위한 정보시스템의 구축은 학제적 성을 지니고 있는 사회과학 전반에 대한 이해와 특성을 파악함으로써 가능하다. 사회과학의 연구대상은 인간 상호작용에 관한 지식의 전반적인 분야를 포괄하고 있어 많은 주제분야가 서로 중복되거나 상호 호환적인 성격을 지니고 있기에. 사회과학 정보시스템이 이용자의 정보요구에 만족을 주기 위해서는 이용자의 유형, 정보요구의 형태 및 그 해결방안에 일차적 관심을 가져야한다. 사회과학 분야의 정보유통 체제를 살펴보면, 대부분 통계자료나 단편적인 데이타로 시작되는 원자료가 사회과학자나 연구자에 의해 "지적 변환(intellectual transformation)" 과정을 거쳐 논문이나 저서 등과 같은 정형화된 문헌의 형태로 나타나게 된다. 정형화된 문헌이 다른 이용자의 요구에 효율적으로 이용되기 위하여 다시 "서지적 변형(bibliographic transformation)" 과정이 수반됨으로써 도서관이나 정보센터의 정보시스템에서 문헌검색이 가능하게 된다. 정보기술의 발달과 보급 이전에는 서지적 변형 단계에서 대부분 정보제공시스템의 역할이 종결되었으나, 최근 정보기술의 활용으로 서지적 변형 후 각종 정보자료의 색인과 초록 및 네트웍 화를 통한 자동화 과정이 이루어짐으로써 이용자의 정보요구에 최대의 만족을 제공할 수 있는 정보자료의 체계적인 분석과 효율적인 통제로 포괄적인 정보관리 차원으로 이전되고 있음을 알 수 있다. 사회과학 분야를 담당하고 있는 사서를 대상으로 실시한 설문조사에서 새로운 정보기술의 활용에 따른 정보전문가의 인지적 혹은 업무 적 변화가 매우 긍정적인 방향으로 뚜렷이 나타나고 있음을 알 수 있다. 정보기술을 이용하고 있는 대부분의 사서들은 정보기술이 그들의 정보봉사 업무를 쉽게, 빠르게. 그리고 정확하게 처리하고 있으며, 새로운 정보기술 습득에 호의적인 반응을 보이고 있다. 아울러 정보기술의 이용에 따른 추가적인 책임이나 의무가 수반되고 있는 것으로 나타나고 있으며, 정보기술이 정보전문가의 역할을 완전히 대체할 정도로 위협을 느끼고 있지는 않는 것으로 조사되고 있다. 종합적인 반응은 대부분의 사서들이 정보 봉사 업무에 정보기술의 활용을 매우 바람직한 것으로 보고 있으며. 이용자 요구를 극대화하기 위한 정보관리에 필수불가결 한 도구로 인식하고 있다. 과거의 유능한 사서나 정보전문가는 자관의 정보원에 대한 철저한 이해로 이용자의 요구에 봉사하는 것으로 간주되었으나, 현재 그리고 미래의 유능한 정보전문가는 자관은 물론 국가적 혹은 세계적인 정보원에 접근할 수 있는 정보원 관리 능력은 물론 정보기술의 활용과 이용자에 대한 교육적 능력을 동시에 지녀야 할 것으로 여겨진다. 이러한 관점에서 사회과학 분야의 정보제공을 담당하고 있는 정보전문가의 새로운 역할을 크게 이용자 보조 역할, 주제전문가 역할. 시스템 전문가 역할, 그리고 정보원 관리자 역할로 구분할 수 있다.

Considering that decision in conservation treatment for damaged objects should consider not only various options of methodology of intervention but also possible consequences of different types of intervention, it is a difficult task to decide and propose clear and safest solution of preserving an object. In addition, it should be constantly challenged by conservators even if it is proved technique or methodology in a past treatment. Therefore, there is no absolute solution which can be applied to all practice but each decision can be different case by case. It is not possible to estimate the way how the present condition of material and environmental aspects would affect to the condition of an object in future. However if conservators keep trying to set out various ways of analysing pro and against effect of past treatments, it would be able to provide useful logics of proving efficiency and appropriateness of a certain treatment. Understanding that the advantage of laser technique is to adopt a way of cleaning an object without making a direct contact, which is different from other techniques, this paper aims at securing stability of laser techniques, although it remains a limitation in the compatibility to all other materials. This study has examined reacting process on the painted pigments against laser beam by using CLSM in order for it to display both the problems from such reacting process and the efficiency of it as a cleaning methodology. It has intended to estimate the result of laser techniques and propose the range of applicability.

Various documents, images, videos and other materials on the web has been increasing rapidly. Efficient search of those things has become an important topic. From keyword-based search, internet search has been transformed to semantic search which finds the implications and the relations between data elements. Many annotation processing systems manipulating the metadata for semantic search have been proposed. However, annotation data generated by different methods and forms are difficult to process integrated search between those systems. In this study, in order to resolve this problem, we categorized levels of many annotation documents, and we proposed the method to measure the similarity between the annotation documents. Similarity measure between annotation documents can be used for searching similar or related documents, images, and videos regardless of the forms of the source data.

We introduce a novel scheme to characterize and index events in TV golf programs using MPEG-7 descriptors. Our goal is to identify and localize the golf events of interest to facilitate highlight-based video indexing and summarization. In particular, we analyze multiple (low-level) visual features using domain-specific model to create a perceptual relation for semantically meaningful(high-level) event identification. Furthermore, we summarize a TV golf program with TV-Anytime segmentation metadata, a standard form of an XML-based metadata description, in which the golf events are represented by temporally localized segments and segment groups of highlights. Experimental results show that our proposed technique provides reasonable performance for identifying a variety of golf events.

Recently, the construction industry is getting more complex and sophisticated having the characteristics of a mega project. Mega project pursues a value that can't be gained with an approach of seeing a project as just a simple sum of different parts but a mutual combination. Hence to reach the goal, program management is needed rather than project management. program management can be seen as a 'total project management' and for an efficient program management prompt support for decision making is required. However, the current supporting method can't fulfill the requirements, therefore, need a tool to support the decision making and a IETM is expected to take this role. Despite the a lot of expected advantages of IETM, it is still difficult to apply because of the frequent changes of information in specifications and laws. In this research, as part of developing a IETM, we aim to propose a system frame which is based on the analysis of processes of a project. Moreover, based on this frame, a database will be built to contribute towards the application of construction IETM in the domestic construction industry.

As the system development environment moves from single core to multi core-based platforms, it becomes more important to maintain compatibility between single core-based implementations and multi core-based implementations. Moreover, it is very important to support real-time on multi core platforms especially in cases of embedded software or test equipments which need real-time as well as correctness. Since Windows operating system dopes not support real-time in itself, it has been supporting real-time using expensive third-party solutions such as RTX or INtime. So as to reduce this kind of development expenses, in this paper, we propose RTiK-MP(Real-Time implant Kernel-Multi Processor) which supports real-time on Windows using the Local APIC of x86 architectures, and evaluate the performance of the proposed RTiK-MP after deploying it on portable missile test equipments.

u-Park means national parks with environmentally sound information networks and integrated ubiquitous services are available. u-Park is totally managed based on u-IT (Ubiquitous IT Technologies) which provides ubiquitous service through sophisticated resources of national park and establishments. It is necessary in changing the existing park management system into u-IT based u-Park management system that park managers should accept new technology, u-Park management system, and be able to utilize it. The purposes of this research is to analyze managers' acceptance behavior on ubiquitous computing technology. Technology acceptance model (TAM) was introduced to specifies the causal relationships among variables related to managers' technology acceptance behavior. The hypothesized model was tested by surveying 157 managers at 5 national parks in Korea. TAM accounted for 55.2% of the variance in intention to use. The most important finding is that perceived compatibleness was the most influential variable in determining intention to use. This means that u-Park management system should be compatible with manager's task and business style.
