In this paper, we propose the design of railway safety common data model to provide common transformation method for collecting data from railway facility fields to Real-time railway safety monitoring and control system. This common data model is divided into five abstract sub-models according to the characteristics of data such as 'StateInfoMessage', 'ControlMessage', 'RequestMessage', 'ResponseMessage' and 'ExtendedXXXMessage'. This kind of model structure allows diverse heterogeneous data acquisitions and its common conversion method to DDS (Data Distribution Service) format to share data to the sub-systems of Real-time railway safety monitoring and control system. This paper contains the design of common data model and its DDS Topic expression for DDS communication, and presents two kinds of data transformation case studied for verification of the model design.

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.

We consider two components parallel system in which the lifetimes have the bivariate Pareto model with bivariate random censored data. We assume that bivariate Pareto model is affected by common stress which is independent of the lifetimes of the components. We obtain estimators for the system reliability based on likelihood function and relative frequency. Also we construct approximated confidence intervals for the reliability based on maximum likelihood estimator and relative frequency estimator, respectively. Finally we present a numerical study.

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.

보안정책모델은 평가대상제품(Target of Evaluation, TOE)의 보안정책을 비정형적, 준정형적, 또는 정형적 방법을 사용하여 구조적으로 표현하는 한 것이다. 보안정책모델은 보안기능요구사항과 기능명세간의 일관성 및 완전성을 제공함으로써 평가대상제품이 요구사항과 기능명세간 불명확성으로 인한 보안결점을 최소화할 수 있도록 보증성을 보장한다. 이러한 이유로 ISO/IEC 15408(공통평가기준. CC) 등 IT 제품 및 시스템의 보안성 평가기준의 고등급 평가에서 보안정책모델을 요구하고 있다. 본 논문에서는 보안정책모델의 개념과 관련 연구 및 공통평가기준의 보안정책모델 보증요구사항을 분석하여 보안정책모델 평가방법을 제시한다.

In the community of software engineering, diverse modeling languages are used for representing all relevant information in the form of models. Also many different models such as business model, business process model, product models, interface models etc. are generated through software life cycles. In this situation, models need to be integrated for enterprise integration and enhancement of software productivity. Researchers propose rebuilding models by a specific modeling language, using a intemediate modeling language and using common reference for model integration. However, in the current approach it requires a lot of cost and time to integrate models. Also it is difficult to identify common objects from several models and to update objects in the repository of common model objects. This paper proposes software model integration using metadata model based on Linked data. We verify the effectiveness of the proposed approach through a case study.

Radio frequency identification (RFID) is an established technology and has the potential, in a variety of applications, to significantly reduce cost and improve performance. As RFID-enabled applications will fulfill similar tasks across a range of processes adapted to use the data gained from RFID tags, they can be considered as software products derived from a common infrastructure and assets that capture specific ions in the domain. This paper discusses a framework that supports the development of RFID-enabled applications based on a business process family model (BPFM), explicitly representing both commonalities and variabilities. To develop this framework, common activities are identified from RFID-enabled applications and the variabilities in the common activities are analyzed in detail using variation point concepts. Through this framework, RFID data is preprocessed, and thus, RFID-enabled applications can be developed without having to process RFID data. Sharing a common model and reusing assets to deploy recurrent services may be considered an advantage in terms of economic significance and the overall product quality afforded.

Distribution systems for operating the various systems should be operated organically. Distribution systems for organic operations extend the functionality of the system and system integration for the extension is doing. However, in systems integration for each unique non-standard definition of linkage and exchange systems are used. Non-standard definition of a unique linkage and exchange systems in the maintenance and expansion will result in many negative results. To solve these problems, the system and the exchange of information about the links between systems should define standards. IEC (International Electrotechnical Commission) power to solve these problems in the field of the Common Information Model (Common Information Model, CIM) standard (IEC61970, IEC61968) is defined as the transmission and distribution system integration and standardization for the exchange of information. In this paper, standardized system for building CIM-based distribution automation system should describe the process of building. In addition, the process of establishing a common information model needed (CIM) defined and associated services for a defined set of models is proposed in the standardization process.

In this study, we collect various side effect pairs which are appeared frequently at many drugs, and select side effect pairs that have higher severity. For every selected side effect pair, we extract common genetic networks which are shared by side effects' genes and drugs' target genes based on PPI(Protein-Protein Interaction) network. For this work, firstly, we gather drug related data, side effect data and PPI data. Secondly, for extracting common genetic network, we find shortest paths between drug target genes and side effect genes based on PPI network, and integrate these shortest paths. Thirdly, we develop a classification model which uses this common genetic network as a classifier. We calculate similarity score between the common genetic network and genetic network of a drug for classifying the drug. Lastly, we validate our classification model by means of AUC(Area Under the Curve) value.

With the advent of high technologies such as the 4th Industrial Revolution and artificial intelligence and big data, efforts are being made to solve urban problems and improve the quality of life by applying new technologies in the smart city field. In addition, as carbon neutrality has emerged as an important issue due to global warming, smart city energy platform technologies such as urban energy management, efficiency improvement, and carbon reduction are in the spotlight. In order to effectively manage urban energy, energy resource information such as electricity, water, gas, hot water, heating, etc. must be collected from the management system of various energy utilities and managed on the central platform. The centrally integrated data is delivered to external city management systems that require city energy information through an energy platform. This study developed a CIM profile for smart city energy monitoring required to provide energy data to external systems. Electric data model were designed using the CIM class of IEC 61970, and water, gas, and heat data model were designed in compliance with the UML-based design ideas of IEC 61970.
