As a way to solve the side effects of urban development, a smart city with information and communication technology converges in the city is being built. For this, a smart city platform should support the development and integration of smart city services. Therefore, the underlying technology and the functional and non-functional requirements that the smart platform must support were analyzed. As a result of this, we classified the Internet of Things, cloud computing, big data and cyber-physical systems into four categories as the underlying technologies supported by the smart city platform, and derived the functional and non-functional requirements that can be implemented and the reference model of the smart city platform. The reference model of the smart city platform is used for decision-making on investment in infrastructure technology and the development scope of services according to functional or non-functional requirements to solve specific city problems for city managers. It provides platform developers with guidelines to identify and determine the functional and non-functional requirements and implementation technologies of software platforms for building smart cities.

The current technological revolution pushes forward the innovation in the library information systems. This study proposes functional requirements and an architectural reference model of Semantic Library, recognized as a prototype of next-generation library information systems, that is a seamless convergence of the library information systems and the Internet technologies. Semantic Library can realize semantic interoperability and integration based on ontology and metadata, and also renovate information services for users with openness, sharing, participation and collaboration. Semantic Library will be effectively implemented by means of service-oriented architecture and the logical structure of FRBR. In this study, a reference model of Semantic Library consisting of 6 horizontal layers and 3 vertical elements is presented as a next-generation model of library information systems.

Much research has been recently accomplished for standardization in cloud computing. However, little research on standardization of data sharing and exchanging has been studied. Most of all, the corresponding standardization organization suggests no specific standardization items and reference model. This paper defines the current standardization problems and proposes a set of specific standardization items and a reference model for supporting the semantic interoperability. To achieve the goal of this paper, the overall standardization trend in cloud computing is first analyzed. Especially, this paper describes the status of standard development for addressing the semantic interoperability of data. This paper also defines the potential standardization items based on the concepts of standards in the data exchanging and management field, which are used for developing standards in various fields. Finally, the reference model is describe to show the relationships between items and overall semantic interoperability process. This paper can be used as a guideline for development of standards and also can facilitate standardization of cloud computing.

ITA (Information Technology Architecture) satisfies the requirements of information system, supports the information used in the institution's business to guarantee the interoperability and security, and analyzes the components of information system. ITA consists of EA (Enterprise Architecture), TRM (Technical Reference Manual) and SP (Standard Profile). The SP, one of the major components of ITA, is a set of information technology standards. In this paper, to construct and utilize the ITA, we mention the applications of information technology about the SP system implementation based on the TRM. The SP management system implemented in this paper is the first trial in Korea, and designs the software with object oriented programming languages such as JSP and Java. Moreover the basic and detailed specification based on the UML notation, system design using the component and system design pattern consisting of software architectures enhance the software reusability. And the constructed system in this paper shows less maintenance cost by using the public softwares such as Linux system, Korean DBMS, Apache and Tomcat, etc. Finally, the system includes the SP reference system which is used in the other institutions and cannot be found in other institutions. Also it includes the additional diverse service modules which support the subsequent processing for the establishment and revision of standards via internet.

정보통신기술의 발달로 인하여 최근 가업의 제품수명주기는 점점 짧아지고, 성장산업과 사양산업의 전환도 급격해졌다. 급변하는 정쟁 환경 속에서 기업의 가치사슬을 전략적으로 통 합하고, 핵심역량을 극대화하기 위해서 c- Commerce, RTE, 협업 등의 가상기업 관련 개념이 부상하고 있다. Ubiquitous 환경에서 기업 경쟁력을 제고하기 위한 목표로서 협업 네트워크를 기반으로 하는 가상기업으로의 전환이 필수적이다. 본 연구는 기존에 논의되었던 가상기업의 정의 및 개념에 대해 문헌연구 및 사례조사를 통해 가상기업의 확장된 범주를 알아보고, 가상기업 연구에 대한 포괄적인 틀을 제공하고자 한다. 또한 가상조직, 협업 네트워크 등의 가상기업 관련 문헌연구를 통해 u- Business 환경의 가상기업 연구의 참조모델을 제시하고, 연구방법론을 적용하여 분석, 연구하여 가상기업의 연구를 이해하고 흐름을 분류하고자 한다. 본 연구결과는 Ubiquitous 환경에 민첩하게 대응하고자 하는 기업들에게 환경 변화에 따른 전략 및 비즈니스 모델의 수정에도 의미를 제공하고자 한다.

OMG (Object Management Group) published a security service specification, called CORBA (Common Object Request Broker Architecture) security reference model because the integration of security and object-oriented techniques was critical for successful deployment of distributed object systems. The CORBA security reference model treats access control as an implementation independent semantic concept but has incomplete semantics of the access control function. Because of such imcompleteness it is difficult for the system administrator and the CORBA security implementor to have the same understanding for the meaning of access control in the CORBA security. We propose a formal model for access control the CORBA security using the formal description language, which is called Z language based on typed set theory. The proposed model provides concrete semantics of the access control function to both the system administrator and the implementor.

기존에 운영되고 있는 공공시설관리 시스템들을 효율적으로 관리하기 위해서는 유지관리 모형이 표준화되어 범정부EA 지원시스템에 목표아키텍처로 등록되고 더 나아가서는 범정부 표준시스템으로 만들어 필요한 기관에 보급할 필요가 있다. 이 연구에서는 도로, 터널, 철도 등 인프라 시설관리 정보시스템을 구축하는데 필수적인 성과참조모델을 범정부EA 관점에서 제시하였다. 제시한 참조모델을 기준으로한 자산관리모형 아키텍처 모습이 GEAP에 등록 관리 된다면 이것을 바탕으로 타 기관에서 향후 정보시스템을 구축할 때 사전에 파악하고 활용하도록 제안 할 수 있을 것이다.

Recently, convergence phenomena among industries are appeared with the rapid development of information and communication technology and technology convergence also is emerging as a key issue. Especially, geospatial information industry may be expected to conduct a role as a pioneer in this convergence era. In order to do this, all fields of geospatial information should be classified systematically and interoperability and compatibility among geospatial information systems should be acquired. In this paper, a technical reference model of intelligent geospatial information is proposed to show a hierarchical technical system in the field of geospatial information. The model is developed with five core research projects of Korean Land Spatialization Group (KLSG) and includes also the scope and importance of core technology in the system. The model would be helpful to manage and control all projects of KLSG.

Digital Twin for Land(DTL) is one of the national work projects in the Korean New Deal but there aren't still any standards and technical guides which would need to construct the DTL. This study presents the policies to develop reference model and data model based on geo-spatial information standards to ensure interoperability for the DTL. In this paper, we first extract the implications through reviewing definitions of Digital Twin used in various literatures and international standardization trends on Digital Twin. In addition, this study attempts to conceptualize the DTL through various ways such as defining the DTL and characterizing DTL domains. Finally, we propose three policies on the standardization of the DTS: (1) DTS reference model by using RM-ODP, (2) three-steps hierarchical data models, and (3) model registry to manage the data models efficiently. The proposed policies of the study would contribute to establish a way for DTS's standards development over the coming years.
