  • Recently, discussions on Metaverse, which represents the transcendent world, have been dominant for some time. Cases related to the Metaverse are introduced through various media and are continuously attracting attention as the next generation of the Internet. This study reviews the business model and the ecosystem overview, focusing on service cases related to the Metaverse. The widely used business models include content production and sales, media brokerage fee, and marketing fee. The Metaverse ecosystem is formed around games, with major players in game production, authoring tool & support SW, intelligent cloud service, and game platform expected to lead the market. Results show that a strategy to secure the leadership of the Metaverse, such as the business model expansion conditions, a strategy to foster a game-oriented Metaverse ecosystem, and technology development for the realization of the ultra-realistic Metaverse, is necessary.

  • Many researchers have carried out studies related to programming languages since the beginning of computer science. Besides programming with traditional programming languages (i.e., procedural, object-oriented, functional programming language, etc.), a new paradigm of programming is being carried out. It is programming with natural language. By programming with natural language, we expect that it will free our expressiveness in contrast to programming languages which have strong constraints in syntax. This paper surveys the approaches that generate source code automatically from a natural language description. We also categorize the approaches by their forms of input and output. Finally, we analyze the current trend of approaches and suggest the future direction of this research domain to improve automatic code generation with natural language. From the analysis, we state that researchers should work on customizing language models in the domain of source code and explore better representations of source code such as embedding techniques and pre-trained models which have been proved to work well on natural language processing tasks.

  • Owing to the need to establish a cooperative-intelligent transport system (C-ITS) environment in the transportation sector locally and abroad, various research and development efforts such as high-tech road infrastructure, connection technology between road components, and traffic information systems are currently underway. However, the current central control center-oriented information collection and provision service structure and the insufficient road infrastructure limit the realization of the C-ITS, which requires a diversity of traffic information, real-time data, advanced traffic safety management, and transportation convenience services. In this study, a network construction method based on the existing received signal strength indicator (RSSI) selected as a comparison target, and the experimental target and the proposed intelligent edge network compared and analyzed. The result of the analysis showed that the data transmission rate in the intelligent edge network was 97.48%, the data transmission time was 215 ms, and the recovery time of network failure was 49,983 ms.

  • The COVID-19 pandemic that occurred in 2020 had an impact on nearly every organization, including the technology-oriented ones. The effects have ranged from minimal hazards to serious interruptions, but also thriving enterprises, depending on the various industry areas of the companies. During this period, the ability to move quickly and to be resilient have been necessary for survival. To fight the pandemic, software developers worldwide had come up with several technological developments and advancements. This paper will focus on the changes COVID-19 brought to software development, the processes that software firms followed during the pandemic, and any recommendations needed to help software development during pandemics.

  • The purpose of this study is to objectively grasp the effect of the engineering education innovation support project among the national engineering-related financial support projects by dividing the groups according to the participation of support projects from 2018 to 2020 and dividing the university performance. As a result of the research the engineering education innovation support project has been consistently producing excellent results of field-based engineering education such as field-oriented industrial-educational collaboration capstone design, technology commercialization, and development and operation of corporate-linked education. It was found that the results showed that the dropout rate of college were lowered. In the future, it needs to be prepared as a place for new and free trials, innovations, and opportunities so that the engineering education innovation support projects can become the mother of other business groups.

  • 서비스 지향 아키텍처(Service-Oriented Architectrue : SOA)개발 프로젝트에서 서비스를 식별하는 단계는 가장 중요한 단계 중에 하나로써 이후 개발단계에서 성공적인 결과를 낳는데 큰 영향을 미친다. 더욱이 잘못 식별된 서비스는 향후 상세설계 및 구현시 여러 차례에 걸친 반복(iteration) 과정을 불러 일으켜 시간은 물론 비용을 낭비하게 된다. 서비스 식별을 위한 여러 가지 방법이 연구되어 왔다. 그러나 이러한 방법은 경쟁이 치열한 환경에서 경쟁력 있는 솔루션을 생산하기에는 부족한 면이 있다. 즉 잠재적인 시장 경쟁력을 확보하기 위한 방법으로서 고객에게 필요로 하는 서비스를 적절하게 판단하고 식별할 수 있는 서비스 식별방법이 필요하게 된 것이다. 따라서 본 논문에서는 요구공학에 기초를 둔 Value Innovative Requirements Engineering[1]을 적용하여 고객에게 필요한 서비스를 식별하는 방법을 제시하고 있다.

  • 객체 중심의 개발방법은 오브젝트(Object)를 중심으로 프로세스를 표현하고 있으며, 이에 반해 관계형 DBMS 로 표현 되는 데이터 영역에서는 테이블(Table)을 기반으로 데이터를 집합체로 제시하고 있다. 이러한 차이로 인해 상호 영역이 맺어지는 영구 저장 영역(Persistence Layer)의 구현과 유지보수에 어려움을 겪고 있다. 최근 대두된 Object-Relation Mapping(ORM) 기술은 이러한 영구 저장 영역의 구현을 상대적으로 쉽고 빠르게 해 준다고 하나 이 또한 기술 적용의 어려움과 테이블의 조합으로 만들어지는 조회와 같은 주요 아키텍처 품질 요소를 만족시키기가 어렵다. 이에 본 논문에서는 영구 저장 영역을 ORM 으로 설계하는 데 있어 고려해야 할 요소들을 정리하여 시스템 별로 적절한 아키텍처 선정에 참조할 수 있는 기준을 제시하였다. 또한 이동통신사의 실제 비즈니스 사례를 들어 ORM 이 적용되지 않은 시스템을 대상으로 제안한 기준에 의해 해당 아키텍처를 선정하고 구현하였으며, 적용 전과 적용 후를 비교하여 주요 요구사항을 만족시키는지 평가하였다.

  • 본 연구에서는 일반적인 시스템 통합 프로젝트에서 발생하는 문제점들을 살펴보면서 새로운 UI 기반의 시스템 통합에 대한 방법을 제시하고자 한다. 시스템통합 프로젝트 진행 시 많은 비용과 시간이 소요되고 있으며 업무시스템의 통합 및 인터페이스 산출물에 대한 검증으로 다양한 이슈들이 발생하고있다. 특히 통합 요구사항의 출현 및 EAI(Enterprise Application Integration), B2Bi(Business-to-Business Integration)에 대한 다양한 요구사항으로 일반적인 어플리케이션 통합프로젝트의 구성에 대한 논의와 새로운 시스템통합 방법론에 대한 정의가 필요하다. 이러한 문제를 해결하기 위하여 기존 방식에서 좀더 진화된 비주얼한 웹 화면통합 기반의 SOA(Service Oriented Architecture) 구축결과 물을 기반으로, VISUAL SOA 기반 프레임워크를 제안하고자 한다.

  • CMMI 도입은, 추진 이후 프로세스가 조직 내에 내재화되기까지, 상당한 기간과 인력이 소요되는 고비용의 조직 활동이다. 따라서 CMMI 도입 결정에 앞서 ROI 분석을 통한 정확한 의사결정이 필요하다. 지금까지의 CMMI 도입과 관련한 ROI산정방식은, CMMI 의 효과산정방식이 구체적이지 않고, 비용측면에 있어서도 프로세스 정의 및 수행비용을 중심으로 산정할 뿐, 지속적인 내재화에 소요되는 비용을 간과하고 있어, 의사결정지표로서 정확성이 결여되었다. 이에 본 논문은 수익성 개선과 생산성 개선에 기반을 두어 효과를 산정하고, 비용 산정은 프로세스 내재화에 따른 지속적 관리활동이라는 특징을 반영하여, 보다 실제적이고 정확한 ROI 분석 방법인 iROI 산정방법을 제안한다. 증명이 어려운 CMMI 투자성과 분석에 활용될 수 있으며, 타 투자분야와 비교할 수 있는 공정한 의사결정 판단근거로서 활용될 수 있다.
