According to a recent survey, over 18,000 government information systems have numerous different functions and characteristics. Although every dataset that is created and maintained in government information systems is declared as a collection of records according to the Public Records Management Act, current electronic records management policies cannot cover dataset records management. This study suggests the policy directions for dataset records management at the national level. It emphasizes the necessity to preserve the appearance and behavior (function) of database systems to ensure the authenticity of dataset records. In addition, this study investigates "emulation" as a representation and long-term preservation methodology for dataset-type records. It also suggests a dataset records model.

Many enterprises and public institutions are building their own server stabilization system. Nevertheless, many web servers including some public institutions have frequent obstacles due to the unexpected causes such as traffic concentration. Data loss during each of these situations and business interruption can cause a huge loss. In this study, we propose high-availability Web system that uses load balancing and session clustering. Each deals with the failure due to the over traffic by distributing incoming requests in the multiplexed web server and provides the continuous services by maintaining session information of the users in case of the failure of some servers.

Currently Korean government is rushing the new electronic government system introduced as 'platform e-government' with big data and cloud computing technologies and systems, ultimately intending to provide the public institution services customized from the integrated counter or window for the heterogeneous resident services. In this regard, this study suggested how to design the new metadata information system in which mutual integration of information systems can take place, where heterogeneous services can be shared efficiently at the application and data unit, as a separate application that can provide a single one- stop service for residents' petition at the integrated level in the back-office based on the public data in possession of each of government ministries and related organizations. If this proposed system is implemented, the achievement of customized public service can be advanced one step forward in processing the petitions of the residents by organically connected link between 'Demand Chain' and 'Supply Chain' in the integrated window. In other words, it could be made possible through the unification of both the 'Supply Chain' performed in the office space of the officials at the back-office level and the 'Demand Chain' performed in the living space of the residents at the front-office level.

This paper is conducted for automatically recommending and providing information services desired by users on websites of local governments and public institutions with vast amounts of information, In this system, we defined a method of collecting data based on the SiiRU CMS system that collects and preprocesses data, and a study that provides curation services (contents and menus) to users through a collaborative filtering algorithm based on machine learning. Also, the data used in the paper is conducted based on about 1 million data collected in 2019. The analyzed data can provide important information that cannot be easily accessed by providing a cloud tag service or recommended menu for users to conveniently view, and the environment configuration that can realize this service to local governments and public institutions is also provided.

인공지능(Artificial Intelligence: AI)이 사물인터넷, 빅데이터, 엄청나게 빠른 컴퓨팅 파워와 결합하고 있다. 이에 따라 인공지능이 인간과 같은 수준의 인지능력을 갖추게 되어 가까운 장래에 개인비서 기능뿐만 아니라 기업의 의사결정이나 고객관리를 비롯한 모든 비즈니스 부문에서 큰 역할을 할 것으로 기대된다. 해외의 주요 기술업체들은 AI를 핵심 R&D 분야로 삼고 각기 Application Programming Interface(APIs) 및 클라우드 서비스를 통한 인공지능 기술의 대중화에 힘쓰고 있으며, 개발자들은 이들 도구를 각자의 애플리케이션에 통합함으로써 수익기회를 창출하고 있다. 국내에서도 대기업 및 공공 R&D를 중심으로 인공지능 기술개발이 추진되고 있으나 관련 시장참여자 전체를 견인할 수 있는 기본 생태계 조성을 위한 정부의 지원이 필요한 상황이다. 본 연구는 인공지능 시장동향과 IBM 인공지능 생태계에 대해 개관하였으며, AI 산업체 의견을 반영한 국내 인공지능 산업 활성화 생태계 조성을 위한 제언으로 AI 플랫폼 지원, 인력문제 해결 그리고 공유의 장 마련이 필요하다는 점을 제시하였다.

전라남도 완도 연안여객선 터미널에서 2018년 10월 연안여객선 현대화편드 1호에 의한 선박 '한일고속페리 실버클라우드호'가 취항식을 가졌다. 국내 여객선 시장은 그간 해외 중고선에만 의존해왔는데 순수 국내 기술로 건조된 여객선이 등장한 것이다. 이에 따라 우리나라 여객선 산업은 기술발전과 디자인 등 그 품질이 향상 될 것이다. 그간 여객선 이용객의 수요는 꾸준히 증가하고 있으나 영세한 규모의 국내 선사는 비용 부담 때문에 신조를 건조하기 어려워 해외 중고선을 수입하였다. 이로 인해 국내 여객선의 실내 인테리어의 노후화, 인테리어 개조에 따르는 선박 성능의 저하 등 다양한 문제점을 가지고 있었다. 따라서 정부는 2018년 현대화펀드를 통해 노후된 연안여객선을 대체할 새로운 선박의 건조를 지원함으로써 연안여객선은 이제 선사의 사적 소유물을 넘어 공공적 성격이 교통수단이 되었다. 이로써 연안여객선은 이동 편의 향상을 비롯하여 승객에게 더 큰 만족을 줄 수 있는 디자인 개선방안이 요구된다.

최근 인터넷의 발달과 함께 웹을 기반으로 하는 클라이언트-서버 분산 구조의 웹서비스 시스템 구조가 점차 확산되고 있다. 게다가, 최근에는 스마트폰을 이용한 스마트폰 애플리케이션이 대중화 되면서, 웹서비스의 활용이 점차 확대되는 추세이다. REST 웹서비스는 일반적으로 기업이나 공공기관에서 자사의 정보시스템의 특정 Open API를 제공하는데 많이 활용된다. 본 연구에서는 REST 웹서비스를 조합/탑재/운용하는 시스템을 제안한다. 본 시스템을 활용하면 서비스 개발자로 하여금 서비스를 조합한 웹서비스를 일반적인 객체지향언어를 통해 개발하고 컴파일 후 업로드 하면 손쉽게 서비스를 운용할 수 있다. 본 논문에서는 REST 웹서비스 조합/탑재/운용 시스템을 제안한다. 웹서비스 조합/탑재/운용 시스템은 REST 웹서비스 개발자로 하여금 웹서비스를 손쉽게 조합하여 컴파일한 후 업로드함으로써 손쉽게 조합 REST 웹서비스를 운용할 수 있도록 한다. 이를 통해 REST 웹서비스 개발자들은 일반적인 객체지향언어를 통해 개발하고 업로드 할 수 있으며, 본 논문에서 제안하는 시스템을 통해 REST 웹서비스를 운용할 수 있다.

In the digital environment, electronic records are explosively increasing, but there are little concerns on how to effectively manage and service. On-Nara 2.0 and record management system, the information system of records production and management stage, are being developed and distributed on the cloud base. Archives management system requires the acquisition of new record management techniques because they need to acquire and manage various types of private records as well as public records. In this paper, we will discuss automation and intelligent technologies for archives management.

Both Platform as a Service (PaaS) as one of the cloud computing service models and the e-government (e-Gov) standard framework from the Ministry of the Interior and Safety (MOIS) provide developers with practical computing environments to build their applications in every web-based services. Web application developers in the geo-spatial information field can utilize and deploy many middleware software or common functions provided by either the cloud-based service or the e-Gov standard framework. However, there are few studies for their applicability and performance in the field of actual geo-spatial information application yet. Therefore, the motivation of this study was to investigate the relevance of these technologies or platform. The applicability of these computing environments and the performance evaluation were performed after a test application deployment of the spatial image processing case service using Web Processing Service (WPS) 2.0 on the e-Gov standard framework. This system was a test service supported by a cloud environment of Cloud Foundry, one of open source PaaS cloud platforms. Using these components, the performance of the test system in two cases of 300 and 500 threads was assessed through a comparison test with two kinds of service: a service case for only the PaaS and that on the e-Gov on the PaaS. The performance measurements were based on the recording of response time with respect to users' requests during 3,600 seconds. According to the experimental results, all the test cases of the e-Gov on PaaS considered showed a greater performance. It is expected that the e-Gov standard framework on the PaaS cloud would be important factors to build the web-based spatial information service, especially in public sectors.
