  • Building Information Modeling(BIM) technology continues to develop and is now being applied to infrastructure facilities. As smart technology based on BIM is applied to the construction industry, the construction of the same data in a common environment is considered to be a very important step in various applications. This study was conducted on methods to establish an open BIM-based airport facility information common data environment. Therefore, this study develops the element technology to establish a common data environment for the integrated management of airport facility information, and aims to standardize data in the common data environment among various technologies and applications. In order to achieve the aim, in this study, the required technologies were derived by examining the common data environment and examining the civil engineering facility field and the case of integrated airport facility management. Through this, standards and development for information standard framework, information requirement level, BIM guidebook, and BIM library were developed in connection with national and higher standards. Through these standards, it is expected that the integrated management of various airport facilities will be efficiently carried out through a standard data platform in the future.

  • There are a great number of Internet-connected devices and their information can be acquired through an Internet-wide scanning tool. By associating device information with publicly known security vulnerabilities, security experts are able to determine whether a particular device is vulnerable. Currently, the identification of the device information and its related vulnerabilities is manually carried out. It is necessary to automate the process to identify a huge number of Internet-connected devices in order to analyze more than one hundred thousand security vulnerabilities. In this paper, we propose a method of automatically generating device information in the Common Platform Enumeration (CPE) format from banner text to discover potentially weak devices having the Common Vulnerabilities Exposures (CVE) vulnerability. We demonstrated that our proposed method can distinguish as much adequate CPE information as possible in the service banner.

  • The professional duties of librarians and other information workers involve a generalized body of both theoretical and practical knowledge (the so-called, 'common core') which is a n.0, pplicable worldwide without regard to national boundaries, levels of economic and technical development or cultural context. The current study is an attempt to validate and su n.0, pport this common core concept through a detailed examination of its important role in the sound development of library and information science both as a learned subject and as a profession. Following an initial overview of generally agreed upon core areas in the education and training of librarians and information specialists, with particular attention to the manifold social changes rapidly being effected by computers and communication technology, the focus shifts to the proliferation of academic homes for information science education and its implications for core areas in information science. Of note here is the relationship between information science as a broadly accepted social science discipline and the evolving core curriculum in library schools. To this regard the fact that the popularization of computers and communication technology is increasingly blurring the once-sharp differences between traditional librarians and information specialists naturally favors common core concept. Major figures in library and information science education such as Shera, Saracevic and Foskette su n.0, pport this concept and have already identified its theoretical infrastructure. Finally, UNESCO and IFLA are also stressing the common core cure curriculum for library and information science both as guidelines for the Third World and as a means to achieve universally accepted academic standards. In conclusion, the search for a comprehensive common core curriculum in library and information science education is still in the elementary stages. The task of identifying the components of this common core is among the most crucial responsibilities facing today's educators and professionals for the successful elaboration of a common core would enable us to attain three highly desirable professional goals: 1) To determine the basic concepts and principles of library and information science. 2) To serve as the base for further professional education and specialized research. 3) To offer enhanced o n.0, pportunities for integrated library and information science education programs by providing a genuine two-way communication channel between the library and information science professions.

  • Because conventional switching converters have been usually using unbalanced circuit topologies, parasitic capacitance between the drain/collector of an active switch and the frame ground through its heat sink may generate the common-mode conducted noise. We have proposed a balanced switching converter circuit, which is an effective way to reduce the common-mode conducted noise. As an example, a boost converter version of the balanced switching converter was presented and the mechanism of the common-mode noise reduction was explained using equivalent circuits. This paper extends the concept of the balanced switching converter circuit and presents a buck-boost converter version of the balanced switching converter. The feature of common-mode noise reduction is confirmed by experimental results and the mechanism of the common-mode noise reduction is explained using equivalent circuits.

  • Lesson learned from the Gulf War, Information systems should be interoperable and integrated for taking information superiority. But most of Information systems that have been developed and operated by military departments are stove-pipe systems that are built over and over again incompatible ways even when requirements are the same, or slightly difference between systems. As a results of this development way, those systems have poor interoperability and portability. But, If some common functions could be extracted, developed as a set of extensible building blocks, the software for common functions could be reusable. Therefore interoperability would be improved because common software is used across systems for common functions. This concept led the development of COE(Common Operating Environment). US and UK COE have been developed and being implemented for the purpose of achieving above goals. Recently Korean Military try to develop the architecture of COE, but it is not easy because of the lack of COE concept, COE development methodology as well as expert In this paper we suggest Korean Common Operating Environment Implementing Strategy based on analysis of US and UK COE that have being implemented to their military systems.

  • Multilingual machine translation means the machine translation that is for more than two languages. Common transfer means the transfer in which we can reuse the transfer rules among similar languages according to linguistic typology. Therefore, the multilingual machine translation based on common transfer is the multilingual machine translation that can share the transfer rules among languages with similar linguistic typology. This paper describes the linguistic modeling for multilingual machine translation based on common transfer under development. This linguistic modeling consists of the linguistic devices such as 1) multilingual common Part-of-Speech set, 2) multilingual common transfer format, 3) multilingual common transfer chunking, and 4) multilingual common transfer rules based on linguistic typology. Validity of this linguistic modeling for multilingual machine translation is shown in the simulation. The multilingual machine translation system based on common transfer including Korean, English, Chinese, Spanish, and French will be developed till 2018.

  • In view of the deficiencies of existing weighted similarity indexes, a hierarchical clustering method initialize-expand-merge (IEM) is proposed based on the similarity of common neighbors for community discovery in weighted networks. Firstly, the similarity of the node pair is defined based on the attributes of their common neighbors. Secondly, the most closely related nodes are fast clustered according to their similarity to form initial communities and expand the communities. Finally, communities are merged through maximizing the modularity so as to optimize division results. Experiments are carried out on many weighted networks, which have verified the effectiveness of the proposed algorithm. And results show that IEM is superior to weighted common neighbor (CN), weighted Adamic-Adar (AA) and weighted resources allocation (RA) when using the weighted modularity as evaluation index. Moreover, the proposed algorithm can achieve more reasonable community division for weighted networks compared with cluster-recluster-merge-algorithm (CRMA) algorithm.

  • In this paper, We introduce effective handoff method from W-COMA system of 3$^{rd}$ generation to 15-95 system of 2$^{nd}$ generation. In case of this handoff, Ms should know long code state using traffic channel, timing information and pilot offset of 26 synchronous system during the compressed mode. So We establish additional common channel in order to obtain handoff information. Common channel transmits same information from all base stations and provides MS with timing information of zero offset. long code state and timing of super frame for sync. channel. Therefore during the compressed mode. MS can obtain information for handoff using common channel..

  • 디지털 정보환경의 변화에 따라 이용자의 서비스요구는 다양해지고 복잡해졌다. 본 논문에서는 미국 대학 도서관을 중심으로 도입 확산되고 있는 Information Commons의 정의, 개념, 유형 등에 대한 이론적 연구를 진행하였다. Information Commons는 단순한 도서관 시설이나 공간이 아니라 디지털 정보환경에서 비롯된 이용자의 다양한 정보요구를 이행하기 위한 협력적 서비스의 제공, 인적자원의 제휴, 물리적인 공간 및 시설의 재정의가 수반된 통합적 서비스 모델이라고 할 수 있다. Information Commons의 성공적인 도입 및 구축을 위해서는 디지털 정보자원에 대한 접근, 유기적이거나 연속적인 서비스의 제공, 이용자 중심의 서비스를 제공하기 위한 자원의 통합이 선행되어야 한다.

  • 정보환경과 이용자 요구의 변화, 그리고 이에 따른 도서관 역할변화에 대한 논의가 활발해짐에 따라 정보와 정보기술, 교육, 학습, 그리고 문화적 기능을 통합한 Information Commons의 개념에 대한 관심이 높아지고 있다. 하지만, Information Commons를 도입하기 위해서는 근본적인 요소에 대한 고려와 적용을 위한 모델이 필수적이다. 따라서, 본 연구는 Information Commons 도입을 위한 요소의 제시 및 적용과정의 제안과 함께, Information Commons의 적용이 비교적 잘 이루어져 있는 Arizona 대학도서관과 Indiana 대학도서관의 Information Commons를 모델로 S대학도서관에 Information commons의 개념을 도입한 가상의 리노베이션을 시도해 보았다. 이는 Information commons 적용의 예를 제시함으로써 보다 활발해질 논의에 대한 사례를 제공하기 위해 이루어졌다.
