본 연구는 고강도 콘크리트 실용화의 일환으로 국내에서 시판되고 있는 고성능 감수제의 품질성능을 평가하기 위한 것이다. 이러한 연구를 위하여 8종류의 고성능 감수제를 대상으로 첨가량에 따른 특성을 비교하였다. 또한 경시변화에 따른 특성을 비교, 분석하기 위하여 슬럼프, 공기량 그리고 압축강도비를 측정하였다. 이 때 고성능 감수제의 품질성능 평가 규준는 JASS 5T-402 규준에 따라 실시하였다. 실험결과 국내에서 시판되는 고성능 감수제는 공기량, 앞축강도비에 대해서는 모두 만족하였지만 슬럼프 경시 저하량은 DA를 제외한 모든 고성능 감수제가 규준치를 초과하였다. 따라서 현장에서 고강도콘크리트를 생산할 경우 배합방법이나 첨가방법을 개선하여 시공성을 확보하는 방안이 필요할 것이다.

Many Asian countries operate the national quality award systems. Most of the evaluation criteria of the award systems are generally based on the MalCom Baldrige National Quality Award System of U.S.A. which started since 1987. But their operation systems for awards are different by countries. Comparing the differences among them can give a good benchmark for Korean Quality Award systems. There are poor empirical results that the Korean Quality Awards systems improve the performances of the organizations awarded. This paper proposes some suggestions for the effective operations of Korean quality award systems through the comparison among Asian countries' awarding systems.

대학의 게임개발 프로젝트에서 품질관리를 수행할 때 폭포수 개발과 같은 전통적인 개발방법론을 적용하기는 어려움이 있다. 이에 대한 대안으로 신속한 개발을 진행하는 애자일 방법론의 적용을 권고하고 그 중에서도 일정한 주기를 기반으로 실행하는 스크럼 방법론의 적용방안을 제시하였다. 본 논문에서는 스크럼 방법론을 학기의 상황에 따라 적용할 수 있도록 일부 원칙을 수정하여 제시한다. 수정된 스크럼 방법을 적용할 경우 보다 체계적인 프로젝트 진행과 품질관리가 가능할 것으로 판단된다. 스크럼의 적용 후에는 회고 과정을 거쳐 프로세스를 지속적으로 개선하는 과정도 필요하다.

The next generation communication environment consists of various wireless access networks with distinct features that are configured as an overlay topology. In the network environments, the frequency of hand overs should be minimized and the error propagation should be solved in order to provide high-quality multimedia services to mobile users. Therefore, we propose an performance enhancement approach, based on mSCTP, that provides high quality multimedia services to mobile users by ameliorating the error propagation problem. We utilizes the following four functions: 1) the separation of transmission paths according to the types of frames. 2) retransmission strategy to minimize the loss rate of frames, 3) Foced vertical handover execution by utilizing bicasting, 4) using the stability period in order to reduce the effect of the ping pong phenomenon. The simulation results show that the proposed approach provides seamless multimedia service to mobile users by achieving error resilience.

다양하고 복잡해지는 소프트웨어 프로젝트를 효율적으로 수행하기 위한 방법론들 중에서 프로세스 평가와 개선에 대한 관심이 높아지고 있다. 그러나 소프트웨어 프로세스 개선을 위한 방법론들은 조직이 비즈니스 목표인 정량적인 품질 관리에 도달하게 하기 위한 측정과 분석활동에 대한 구체적인 가이드라인을 제시하지 않는다. 본 연구는 효과적인 정량적인 프로세스 및 프로젝트 관리를 위해 Six Sigma 방법론을 도입, CMM 레벨 2의 예측공수모델에 적용하여 제시, 프로세스 측정과 분석활동의 개선 가능성에 대해 모색하고자 한다.

The Cultural Heritage Administration is operating the resident supervision and non-resident supervision system to prevent poor repair and ensure the quality of cultural heritage repairs And recently, responsible supervision system was introduced to enhance the supervision of cultural heritage repairs. However, many problems have arisen in the operation of the supervision work, and need improvement. Accordingly, this study improved the resident and non-resident supervision of cultural heritage repair and developed work guidelines for the responsible supervision. First, this research has derived unreasonable sectors and problems of work guidelines for resident supervision about cultural heritage repair and has suggested supervision work guidelines which are improved. Second, we have derived the problems of work guidelines for non-resident supervision about cultural heritage repair and has suggested non-resident supervision work guidelines which are improved. Third, this paper has proposed the development direction and detailed supervision work to perform responsible supervision as a result of the adoption of the supervision system for cultural heritage repair.

The demand for promoting industrialization construction methods is increasing in Korea to cope with various construction environments, such as the lack of construction engineers, aging construction workers, and the government's 52-hour workweek policy. The industrial housing accreditation system was introduced in 1992 to recognize and improve the quality of industrial housing, but only six companies are currently certified, and there are no records of constructing industrial houses. Currently, the industrialized housing accreditation system in Korea comprises standards for the recognition, revocation of recognition, and promoting the construction of industrial houses. Therefore, this study analyzed the regulations of the industrialized housing accreditation system, derived the problems of each regulation, and derived improvement directions to promote the industrialized housing accreditation system in Korea. Specific measures include expanding the current industrial housing accreditation scope to quasi (semi)-housing, revising the performance and production standards of industrialized housing, relaxing the building standards, and providing financial support to promote industrialized housing.

The purpose of this study is to identify the current status of institutional research data repositories in the field of science and technology and to suggest ways to activate them. The study conducted literature research, case analysis, and interviews with repository managers both domestically and internationally. The study suggested strategies with a focus on establishing repository regulations and policies, improving awareness of research data sharing, and enhancing research data quality management. First, in terms of repository regulations and policy establishment, it was considered necessary to promote the status of the National R&D Information Processing Standards, a regulation related to research data, and clarify repository basis regulations. Second, to enhance awareness of research data sharing, the need for comprehensive research data education and the identification of exemplary cases were suggested. Third, in terms of strengthening research data quality management, the need for preparation for interaction between researchers-persons in charge-committees, standardization work, and long-term preservation was suggested.
