기존의 노심설계코드는 UNIX 시스템에 구현되어 있기 때문에 설계자가 입력 생성, 코드 실행, 결과 처리/분석 등의 모든 업무를 텍스트 형태로 작업을 수행해야 한다. 이 방법은 문법 오류 및 실행 오류와 같은 인적 오류를 범할 수 있는 문제가 있다. 본 논문에서는 이 문제를 해결하기 위해서 웹 환경에서 노심설계코드를 자동 실행하기 위한 아키텍처를 제안한다. 제안한 아키텍처는 노심설계코드를 직접 처리하는 CGI 프로그램과 WAS를 연동하여 웹에서 모니터링이 가능하다. 즉, CGI 프로그램은 실시간으로 WAS의 명령을 백그라운드로 실행하고, WAS는 CGI 프로그램의 수행 결과를 웹에서 모니터링 한다. 적용사례로써 제안한 방법으로 원자력발전소의 노심설계코드 프로그램을 수행시켜 실효성을 확인한다.

As massive increase in remote work since COVID-19, the boundaries between the inside and outside of corporate networks have become blurred. As a result, traditional perimeter security has stagnated business productivity and made it difficult to manage risks such as information leakage. The zero trust architecture model has emerged, but it is difficult to apply to IT environments composed of various companies. Therefore, using the remote work system configuration as an example, we presented a configuration and methodology that can apply zero trust models even in various network environments such as on-premise, cloud, and network separation. Through this, we aim to contribute to the creation of a safe and convenient cyber environment by providing guidance to companies that want to apply zero trust architecture, an intelligent system that actively responds to cyber threats.

It may not be strange to anticipate that the forth-coming epoch of electronic government would bring us lots of convenience on account of ubiquitous environment with mobile devices. Such environment enables us to access the up-to-date information anytime and also a worker to carry out administration services to perform one's line of duty at anytime with electronic, handy devices such as PDA. What we now recognize from the field of electronic traffic administration services is that the office work flow as well as the public services has been remarkably improved by using of not only text but video and image information under the distributed, mobile environment. One of key requirements of this kinds of services is the feature of exchanging various information among multiple information publishers and subscribers. We call this feature Messaging Services generally The study in this paper focuses on the architecture design of the Messaging Engine software, complying with the pattern-oriented software architecture design methodology. And our contribution also goes to the discovery of three architecture patterns found in the design process and the efficient multi-threading architecture compared to one of the Messaging Engine solutions.

The purpose of this research is to propose a practical guideline for activating EA which has been operated in the public institutions. For this purpose, how EA is being operated in the public sector, was analyzed from the viewpoint of IT Governance and on the basis of the result, key activities for EA managers could be developed. The key activities were also compared between the two different groups in terms of EA Maturity Level and the difference in the key activities between the two were examined. As a result, it was found that the use of EA has effect on building and improving IT management systems. It is suggested that the Relational Mechanism should be better understood and recognized as necessary activities for activating EA. In addition, the higher the level of EA maturity is, the more likely such various effects as the enhancement of IT management system, user satisfaction, IT utilization, and the improvement of business can be produced. This result could be interpreted that such desired outcomes of EA could be realized only when EA is actively utilized.

조직에조직에서 정보기술의 원칙과 Framework이 없는 청사진으로 인해 업무의 통합 및 효율적인 정보기술 관리가 불가능하고, 투자 비용만 증가하게 되었다. 정보기술아키텍쳐 (ITA)를 대상 엔터프라이즈에 적용하기 위해서는 다양한 관점에서 엔터프라이즈를 바라보며 현상을 분석하고 해결 할 수 있는 Framework이 필요하며 이 Framework를 통해 정보기술아키텍쳐가 개발 및 유지 되어야 한다. 따라서, Strategy Layer, Framework Layer, Architecture Layer로 구성된 TAPark Framework를 제안하였다. 먼저, Strategy Layer에서는 EAP를 통해서 정보화 청사진의 원칙과 전략을 수립하고, Framework Layer에서는 기술 참조모델로 HanTRM을 제안하였고 HanTRM 서비스에 해당 표준들을 매핑시켰다. 또한 통합과 상호운영의 근간인 상호운용성 능력모델(LISI-CM)과 조직의 기술 인프라 현황을 분석 및 평가할 수 있는 Control과 정보자산의 통합관리를 제공하는 Asset을 제안하였다. Architecture Layer에서는 Framework을 기준으로 EA, TA를 수행하며 마지막으로 Engineering Layer에 있는 S/W Engineering, Infrastructure를 통하여 효과적으로 정보기술 아키텍처를 개발할 수 있다.

The amount and diversity of information is increasing, as is the information integration connecting data among the related institutions. In the defense field, DTAQ, which is in charge of the quality of military supplies, is attempting to collect and analyze the information which is related with it. In addition, the object of information integration is to expand civil data as well as defense data. There are many ways to integrate data in various environments. In the defense field, which needs enhanced security, it is necessary to establish and apply the information integration methods which are enhanced with more security. In this study, the framework and architecture of information integration was designed by considering task requirements and security conditions. As a result of example application of this framework for information systems to the selected 4 institutions, it was confirmed that the task can be performed through data connections. From the study result, integration architecture which can be applied securely in defense field was suggested. The data accumulated by using this framework with strengthened security are expected to be utilized for the quality improvement of military supplies.

Construction companies are trying to apply process management to their business to improve efficiency in business circumstance of high competition and globalization. Since 1990s, construction firms adopted process management to improve internal and external business structure based on process. It however has a few improvement functions. In addition, business support systems for business process efficiency improvement were developed, but separation between business process and IT system occurred because it focused on function-based individual construction and data input/output. To solve this problem, this study proposed business process and IT integration model for supporting user to use business information and system based on visualized business process and improving use of previous business support system. Business efficiency is expected to be improved with this model which based on integration required business condition(stakeholder, business data, functions of business supporting system). This study developved process model, architecture, and BPA of whole construction management business. According to BPA, it analyzed business process stakeholder, detail activities, and input-output data. And also it examined 12 main business supporting system of Korean construction firms. Based on analyzed data, this study developed business process supporting integration model based on business process through PDCA and CRUD analysis.

Although the Korean government is making great effort to prevent the redundancy in IT investment and efficiently allocate the IT budget, actual achievements are quite limited because of the variety of IT resources and different architecture description among organizations and projects. Thus, a standardized description model of the system architecture is strongly needed to identify the common resources and improve the efficiency of IT investment. Therefore, in this paper, we have developed the function-network matrix model which can be used as the basic template for a standard for architecture description of e-Government systems. The function-network matrix model integrates the function tiers and the network areas into a single unified framework, which enables the functionality of each component and the flow of information clearly visible. Moreover, we described the architectures of Korean e-government’s citizen service systems using our model, resulting in clear demonstration of the similarities and differences between different systems, and easy identification of the common resources. Using the architecture description model developed in this research, the consolidation of national IT resources can be promoted, and non-expert IT users can easily recognize the architecture of their systems. In addition, more efficient and systematic IT resource management can be achieved using our model.
