소프트웨어 개발방법이 컴포넌트기반 개발방법으로 진화하고 최근 들어 형상관리 시스템의 도입이 대두되고 있다. 본 논문은 컴포넌트기반 개발방법론에서 발전한 컴포넌트 형상관리를 다루고 컴포넌트 명세는 정규화된 문서인 XML을 기반으로 하고 있다. 컴포넌트 버전관리와 의존관리는 컴포넌트 이름으로 수행하였다. 컴포넌트 의존정보는 컴포넌트 명세가 합성될 때 합성에 사용된 컴포넌트 이름을 사용하여 이를 반영하고 의존정보로 사용하여 명세서를 통한 버전관리와 의존관리의 가능을 확인하였다.

CBD 개발 방법론의 발전으로 많은 컴포넌트가 개발되면서 소프트웨어의 빠른 기술변화는 시스템 개발 생명주기가 갈수록 짧아지고 있으며, 최근 들어 시스템 개발에 있어서 오프라인보다 온라인으로 시스템 개발이 늘고 있다. 때문에 실시간으로 컴포넌트 형상관리의 필요성이 나타나고 있으며, 보다 향상된 기술의 개발방법이 요구되고 있다. 본 연구에서는 이를 위한 하나의 해결방법인 형상관리(Configuration Management)를 제안하고, 실시간 컴포넌트 형상관리 작업에 필요한 요구사항에 대해 기술하였다.

The study investigated the optimal configuration of SVC (Scalable Video Coding) to apply to the satellite broadcasting service, and compared the performance of the SVC with that of the AVC (Advanced Video Coding). To get the optimal configuration, we analyzed the optimal bit rate allocation between the layers and the optimal scalability which requires the least bit rate for the required PSNR for various kinds of contents using JSVM. As a result of investigation, we found that the optimal bit rate allocation occurs when the bit rate of the base layer is minimum, and the spatial scalability shows the best performance. The performance of SVC is similar to that of AVC for spatial scalability, but it depends on contents.

The smart factory promotion project is a project that improves the entire management environment system, including the production process, using ICT technology. According to the 2019 Smart Factory Survey and Analysis Research Report of the Ministry of SMEs and Startups, small and medium-sized enterprises that introduced smart factories reported positive effects such as increased productivity, improved quality, and reduced costs on average. On the other hand, the survey results of companies that promoted the project despite positive results showed that there was room for improvement. This study dealt with the contents of the survey conducted on companies by the smart factory promotion agency in 2020 regarding the infrastructure configuration for promoting smart factories. We examined the meaningful contents implied by the data related to the infrastructure configuration. These meaningful survey results can lead to more efficient business promotion in the future when promoting smart factory projects.

오늘날, 인터넷의 급격한 증가에 있어서 응답지연과 네트워크 트래픽의 양, 그리고 서버의 부하를 줄이기 위한 파일캐싱은 매우 중요해졌다. 실제로 하나의 네트워크에서 캐쉬를 사용함으로서 트래픽을 줄일 수 있게 되었고, 이것은 파일캐싱이 인터넷 링크의 용량을 늘리기 위한 비용 부분을 개선할 수 있음을 의미한다. 본 논문에서 확장성 문제를 해결하기 위하여 동적 캐쉬 그룹 구성 정책을 소개한다. 모의시험 결과는 본 논문에서 제안한 정책을 사용하는 캐쉬 그룹이 응답지연시간이 줄어들었음을 보여주며, 우리의 캐쉬그룹 구성이 정적 캐쉬 구성보다 더욱 확장성이 있음을 보여 준다.

When we conduct development of a large-size SI project, it is highly necessary to utilize an appropriate application framework which helps to build a qualified software with high productivity in a short period of time. In this paper, we propose the architecture of a dynamically reconfigurable CBD application integration framework that has been used for developing large-scale e-business applications to achieve high development productivity and maintainability. This Integration framework can easily extend its functionalities, and dynamically change its configuration during run time according to the business category, such as applying interaction patterns among main components in software architecture, rules, policies, and environmental parameters. Dynamic reconfiguration has the feature to make applications be easily customized for changeable requirements. Through our application integration framework, huge sizes of contents can be managed according to the business category as well, by keeping configuration informations and huge volumes of source codes. In order to evaluate out application integration framework in terms of performance criteria, we present experimental results of throughputs from the framework by yielding dynamic configuration without any performance degradation.

This subject is about the study on digital contents development of traditional Korean furniture to find our traditional peculiarity that is disappearing gradually in the rapid computerization. In order to carry out this subject, we established some methodology to industrialize the culture, the style, the manufacturing process and the configuration details of traditional furniture in the form of digital contents with reference to books regarding the furniture in Chosun Dynasty and furniture collection in possession of museum, gallery, etc. This study made a database about traditional Korean furniture systematically to be used as basic materials that are available for diverse culture business as a whole with Korean identity in the future. The contents of this study are as follows: 1) Style of traditional furniture 2) Decoration of traditional furniture 3) Manufacturing process of traditional furniture 4) Configuration details of traditional furniture The contents work of traditional Korean furniture was to secure the identity of Korean furniture from the point of culture and to provide an alternative of modernization by re-illuminating the superiority of traditional furniture in discontinuation from the point of industry.

In this study, contents of 'the 2007 revised curriculum handbook' and 16 kinds of mathematics textbooks were analyzed first. The purpose of this study is to examine the understanding state of students at general high schools by making questionnaires to survey the understanding state on contents of chapter of complex number based on above analysis. Results of research can be summarized as follows. First, the content of chapter of complex number in textbook was not logically organized. In the introduction of imaginary number unit, two kinds of marks were presented without any reason and it has led to two kinds of notation of negative square root. There was no explanation of difference between delimiter symbol and operator symbol at all. The concepts were presented as definition without logical explanations. Second, students who learned with textbook in which problems were pointed out above did not have concept of complex number for granted, and recognized it as expansion of operation of set of real numbers. It meant that they were confused of operation of complex numbers and did not form the image about number system itself of complex number. Implications from this study can be obtained as follows. First, as we came over to the 7th curriculum, the contents of chapter of complex number were too abbreviated to have the logical configuration of chapter in order to remove the burden for learning. Therefore, the quantitative expansion and logical configuration fit to the level for high school students corresponding to the formal operating stage are required for correct configuration of contents of chapter. Second, teachers realize the importance of chapter of complex number and reconstruct the contents of chapter to let students think conceptually and logically.
