COVID-19의 확산과 급속한 디지털 전환으로 인해 비대면으로 소통하고 정보를 교류하는 메타버스 플랫폼이 최근 많은 주목을 받고 있다. 하지만 새로운 플랫폼의 등장에도 불구하고 대부분 게임이나 상용 시스템 위주로 적용되고 있으며 학술정보서비스 영역에서의 적용은 요원한 현실이다. 본 연구에서는 기술의 적용 형태와 지향범위에 따른 메타버스의 '증강현실, 일상기록, 미러월드, 가상세계' 등의 4가지 유형과 메타버스 플랫폼 주요 현황을 살펴보고, KISTI에서 제공하고 있는 과학기술지식인프라 통합서비스 ScienceON과 연계하여 디지털 연구환경 조성과 개방형 협업연구 활동을 지원하는 메타버스 플랫폼 키온버스의 제공서비스 유형과 주요 기능 등 학술정보서비스 영역에서의 메타버스 적용방안을 제시하였다. 본 연구는 학술정보서비스에 적용된 메타버스 플랫폼의 사례로서 향후 메타버스 활성화에 기여할 것으로 기대한다.

The purpose of this paper is to provide a convenient platform for bus users and a platform to provide tourist services suitable for bus tourism as integrated services. Recently, the number of FIT tourists for recreational purposes using public transportation is increasing as the bus use environment is improved. Accordingly, we need a tourist platform that meets the needs of tourists. In particular, a bus information providing algorithm is implemented using a bus information public API to more conveniently use the bus information providing system, and a user use behavior data collection module and a data mining module To develop a contents platform based on a bus stop for bus tourism services to FIT tourists using public transportation.

기존의 컴포넌트 기반으로 응용 프로그램을 개발하던 소프트웨어 개발 방법론이 분산 컴퓨팅 환경에서 대규모 시스템 통합의 요구가 생겨남에 따라 서비스-기반 구조(SOA: Service-Oriented Architecture)로 점차 변화하고 있다. SOA를 구현하기 위한 최신 통합 기술인 엔터프라이즈 서비스 버스(ESB: Enterprise Service Bus)상에서 상호 작용하는 시스템 간에 교환되는 데이터 품질을 보장할 수 있다면 더 나은 서비스를 제공할 수 있다. 본 논문은 기존에 개발된 DAQUM(Data Quality Measuring tool)(1)을 이용하여 ESB상에서 통합된 시스템들간의 상호 작용하는 데이터 품질을 보장하기 위한 서비스를 개발한다.

MDO(Multidisciplinary Design and Optimization) can be applied for design of complex systems such as aircraft and SLV(Space Launch Vehicle). MDO System can be an integrated environment or a system, which is for synthetic and instantaneous analysis and design optimization in various design fields. MDO System has to efficiently use and integrate distributed resources such as various analysis codes, optimization codes, CAD, DBMS, GUI, and etc. in heterogeneous environments. In this paper, we present Web Services-based MDO System that integrates resources for MDO using Globus Toolkit and provides organic autonomous execution using automation technique such as Workflow system and agent. And also, it provides collaborative design environment through web user interfaces.

Metaverse is one of the most frequently used words recently, with digitalization accelerated by the COVID-19 pandemic that started in 2019 and the development of information and communication technology. It is expected to bring a new revolution in our life as a whole in user experience. In particular, as telecommuting was adopted in the business area, interest in virtual office services such as digital video conferencing and remote offices, which are similar to the metaverse, has also increased. In this study, a study on the intention to use the metaverse service used in the work environment was applied to the Unified Theory of Acceptance and Use of Technology 2(UTAUT2). External variables for metaverse characteristics, such as self-presentation, telepresence, and technostress, were analyzed and discussed. In this study, PC-based Gather.town and VR-based Facebook Horizon, currently the most well-known and considered usable in work environments, were introduced to potential users and conducted a survey. This study has academic implications in that the research has examined the factors that affect the technology acceptance intention of users who want to apply the metaverse as a work environment based on the UTAUT2 model, unlike previous studies that have been mainly researched on the general metaverse. In practice, it may be helpful to suggest factors that should be considered when firms adopt the metaverse for business purposes.

Recently, the Seoul Metropolitan Government (SMG) has initiated several urban redevelopment projects to revitalize the downtown well equipped for transit oriented development (TOD). Since, TOD should incur higher density development in our context, it has negative impacts on travel patterns, congestion, and urban environmental quality. The purpose of this study is to develop new transportation service index which can facilitate higher density TOD. This study includes relevant foreign case studies, the development of multimodal transportation index, and the impact analysis of TOD when it is applied in the downtown Seoul. In chapter III, it developed a so-called ITLOS, new multimodal transportation service index which shows the possibility of accommodating further development by integrating roadway service index with public transportation service index. The study sets ten policy scenarios by varying densities, and run the Seoul Congestion Management Model (SECOMM) to estimate the sustainable transportation impacts of TOD in the downtown. Travel speed index that only represents the availability of road capacity for development reveal that higher density development in the downtown can deteriorate traffic congestion while improving region-wide transportation level of service in Seoul. Also, it is proved that higher density development is more feasible when using ITLOS as the index because it considers not only available road capacity but subway capacity in the analysis area.

메타버스는 다수 사용자의 협업이 가능한 3 차원 가상현실 환경을 제공한다. 메타버스 공간에서의 현실과 연결된 혹은 현실이 모사된 실시간/비실시간 시뮬레이션은 비용-효율적인 이점을 가진다. 연동-시뮬레이션은 서브시스템들의 통합 시뮬레이션으로, 메타버스 공간에서의 연동-시뮬레이션을 위해 데이터-레벨, 시스템-레벨, 서비스레벨에서 기술 성능 검증 및 메타버스 윤리 검증이 필요하다. 개별 서브시스템이 윤리적으로 동작하는지 뿐만 아니라 연동된 시스템의 활용도 윤리적인가를 살펴보아야 한다. 알고리즘 및 시스템 정책이 반영되어 검증된 모델은 메타버스의 더 적은 위험성을 가지고 자동화된 디지털 사회 체계나 현실세계의 시스템에 적용되어 활용될 수 있다.

In the development of MDMS(Meter Data Management System) based on CIM(Common Information Model), which is international standard in information model and data exchange on power system, the two focused issues are the effective management of data collected in a shorter time period and the way to integrate services supporting legacy system to use the AMI(AMI, Advanced Metering Infrastructure) data. In this paper, we propose MDMS implementation methods and functions in AMI environment which are differ from existing AMR system environments in that the methods support bi-directional service infrastructure. The proposed MDMS in this paper has two unique features, one is the secure of interoperability by utilizing the CIM and ESB, the other is the improvement of field application by implementing system module based on components. On an implementation of smart grid, the result of proposed methods is expected to contribute to the efficient development and operation of CIM-based power system.

최근 차량용 IT 기술이 발달함에 따라 네비게이션, 위치추적, 인터넷 접수, 원격 차량 진단, 사고감지, 긴급구난, 교통정보 등을 제공하는 서비스들이 등장하고 있다. 또한 차량의 편의성과 안정성을 추구함과 동시에 친환경 등에 대한 요구도 증가하고 있다. 그리고 최근 차량 상호간 정보의 교환이 더욱 필요해짐에 따라 차량간의 무선 통신 기능이 중요해지고 있으며 차량 내의 네트워크 기술에 대한 연구도 필요하다. 현재 차량 내 네트워크로는 CAN, LIN, MOST등의 유선으로 된 버스 시스템을 중심으로 한 차량 제어 시스템과 멀티미디어 시스템으로 크게 구분할 수 있다. 그러나 자동차 내에 장치 배선이 복잡해짐에 따라 차량의 무게 증가, 고장율의 증가, 연비 저하 등으로 이어지고 있다. 이러한 문제를 보완하기 위해 차량 내에 무선 센서 네트워크 시스템과의 통합 개발이 요구되고 있다. 본 논문에서는 빠르게 발전하고 있는 차량 내 네트워크에 대한 기술개발 동향을 분석하고, 유무선 통합형 차량 내 네트워크 응용 서비스들을 제시하고자 한다.

The aim of this study is to propose an integrated operation plan of information call services by multi-connecting call services which are now being serviced by each different call number services and by providing one stop service which organically links alternative transportations such as railroad, air, and bus and also related organizations as well as road traffic information. For the objective, we analyzed the current status of Korean and foreign country systems and reviewed operation technology and technical specifications of the integrated system according to 3 steps, i.e. infrastructure procurement, test bed and extended completion, stabilization and high valuable services completion. Throughout the result of this study, traffic information one stop service, convenient service, diverse related information provision service, real-time information provision, and efficient system are expected to be implemented in the traffic information call service.
