지금까지 국가연구개발사업은 체계적인 기술 확보전략이 없었다. 본 연구는 국가연구개발 사업도 기술확보 전략이 있어야 한다고 주장하면서, 국가연구개발사업에 적용할 수 있는 기술확보 의사결정프로세스를 제안한다. 국가연구개발사업은 자체개발(insourcing)과 해외위탁/용역, 라이센스, 공동연구의 외부기술(out-sourcing)으로 유형을 구분하였으며, 이에 적합한 기술확보 유형결정을 위한 다단계 의사 결정프로세스를 제시한다.

내장 시스템(Embedded System)기술은, 정부가 주도하는 기술과제로 여러 응용분야에서 각광을 받고 있다. 본 논문에서는 내장 시스템이 가지는 한계상황 하에서 프로세스가 좀더 빠르게 복구하는 기법을 제안하고자 한다. 빠른 복구를 위해서는 두 가지 조건이 만족되어야 한다. 첫째 조건은 실제 프로세스의 이상이 발생 했는지를 빠르게 감지해야 한다. 기존에는 주기적으로 프로세스를 감시하는 방법들이 많이 사용되었으나 이런 방법들은 내장 시스템에서 빠른 프로세스 복구를 하는데 한계점들이 나타냈다. 따라서 시스템 레벨에서 프로세스 종료를 시키는 시그널(signal)을 훔치는(hooking) 방법[1]과 프로세스 스케줄 순서를 조정하는 방법을 토대로 프로세스의 이상을 빠르게 감지할 수 있다. 두 번째는 한정된 자원 아래서 효율적으로 복구 데이터를 관리 및 복구해야 한다. 기존의 복구 기법에 경우 다양한 자원을 대한 복구를 위해서 자원을 많이 사용하였지만 우리가 사용하는 공유메모리 기법[1]은 자신의 필요한 정보만을 관리함으로써 한정된 자원 환경에서 복구가 가능하도록 하였다.

최근 디지털 컴퓨터와 정보처리기술의 발전과 더불어 원자력 발전소의 계측제어시스템과 같은 안전-필수 시스템에서도 디지털 기술을 채택하기 시작했다. 안전-필수 시스템에 사용되는 소프트웨어는 높은 신뢰도(dependability)가 요구된다. 소프트웨어의 신뢰도는 신뢰성(reliability), 안전성, 보안 등 다양한 속성들로 설명될 수 있다. 소프트웨어의 신뢰도 향상을 위한 프로세스는 결함예방프로세스, 결함허용프로세스, 결함제거프로세스 그리고 결함예측프로세스가 있으며 이들 프로세스는 소프트웨어 수명주기 초반부터 수행되어야 한다. 본 논문에서는 소프트웨어 신뢰도향상을 위한 신뢰도 프로세스 모델과 개발 단계별로 수행되어야 할 신뢰도 태스크를 제시한다.

Military vessels are complex weapon systems consisting of various integrated onboard equipment. Since their acquisition of military equipment takes a long period of time and a prototype ship is deployed and tested, vessel development has relied on its proprietary process. However, due to the growing complexity of onboard equipment technology, application of systems engineering (SE) process has become indispensable. Nonetheless, an effective design process complementing the existing design with the SE has not yet been developed. As such, we have studied an improved basic design process for submarines based on SE. To do so, we analyzed the processes for the basic design, technical review, and requirement management. Included reviews and requirements are SRR, SFR and PDR, and SSRS, SSS, and SSDD. By combining the results in the SE framework, we built an improved basic design process that can be applied in parallel with the SE-based technical review and requirement management. To assess the process, we applied our proposed model to the submarine development undergoing the basic design phase. It is possible to effectively manage the requirements, design artifacts and improve traceability, and also utilize them as test and evaluation materials. The SE-based basic design process is expected to be useful in other kinds of vessel design.

This paper studied the improvement of software process of the software firms. Software process infrastructure level of software process is very important. This study provided that software process infrastructure have an significant influence on the process level, process infrastructure management level, and software process performance. The result showed that software process high level is elevated through management activity of organization infrastructure and technical infrastructure. And organization performance is elevated through fit between process level and quality culture of software process. Problem factors of software process infrastructure improvement is lack of process improvement mind, leadership and investment. Therefore software firms must construct process improvement through supporting of process quality mind and investment with process infrastructure improvement.

The trend of R&D in automotive electronics industry is shifting towards ECU(Electronic Control Units) based on softwares which requires technology convergence to accommodate customers' requests on safety and convenience. The trend requires systemized R&D paradigm which reflects increased role of softwares. As the softwares became the core components in automotive innovation, there has been wide range of efforts to introduce software R&D processes and methodologies such as CMMI, A-SPICE and ISO-26262 etc. However, R&D departments in the industry fields are confronted with conflicts which arise from discrepancies among the individual process. In this study, we focus on suggesting our integrated and systematic R&D process with the aim of alleviating the conflicts and confusions. For this purpose, we analyze the cases of Korean automotive electronics companies to compare various R&D processes in the field and their relationships. Based on the analysis, we derive and suggest our model of R&D process which effectively integrate ISO/TS-16949 for manufacturing quality and CMMI, A-SPICE, ISO-26262 for system with softwares.

The growth of sensor and wireless communication technology enable us to monitor the status of things in real-time. There are many attempts to apply the real-time monitoring in various fields. Especially, the real-time monitoring in facility management fields has attracted much attentions recently. But it is difficult to apply recent technologies including sensor, wireless communication and Geospatial information technologies, etc, to the real situation directly. One of the reasons is that facility managers who are familiar with existing processes may resist the change induced by new technologies. So it is necessary to close the gap between new technologies and existing processes by improving the existing processes prior to putting them in the field. In this paper, we suggest the management process improvement focused on the district heating facilities.

In this paper, we propose a new type of process discovery framework, which is named as control-path-driven process group discovery framework, to be used for process mining and process reengineering in supporting life-cycle management of business process models. In addition, we develop a process mining system based on the proposed framework and perform experimental verification through it. The process execution event logs applied to the experimental effectiveness and verification are specially defined as Process BIG-Logs, and we use it as the input datasets for the proposed discovery framework. As an eventual goal of this paper, we design and implement a control path-driven process group discovery algorithm and framework that is improved from the ρ-algorithm, and we try to verify the functional correctness of the proposed algorithm and framework by using the implemented system with a BIG-Log dataset. Note that all the process mining algorithm, framework, and system developed in this paper are based on the structural information control net process modeling methodology.
