Recently, Distributed computing processing begins using both CPU(Central processing unit) and GPU(Graphic processing unit) to improve the performance to overcome darksilicon problem which cannot use all of the transistors because of the electric power limitation. There is an integrated graphics processor that CPU and GPU share memory and Last level cache(LLC). But, There is no LLC access rules between CPU and GPU, so if GPU and CPU processes run together at the same time, performance of both processes gets worse because of the contention on the LLC. This Paper gives evidence to prove the need of the Cache Partitioning and is mentioned about the cache partitioning design using page coloring to allocate the L3 Cache space only for the GPU process to guarantee GPU process performance.

Recently, numerous government institutions and information service organizations have shown interests in employing ISO 9001 Quality Management System(QMS) to increase their organizational performances. However, due to the gap between the system requirements and the process oriented goals in reality, they have not been able to merit from the ISO 9001 QMS. So, Korea Institute of Science and Technology Information(KISTI) has been designed a process oriented system by incorporating the process analysis results into the existing ISO 9001 system requirements for enhancing organizational competitiveness and promoting productivity through a process standardization. As a result, KISTI has been ISO 9001:2000 certificate in November 11, 2003. And we obtain a improvement of customer satisfaction and efficiency of work, reduction of work processing time using KQMS.

According to software growth, also software maintenance has been continuously improving. In addition, the existing concept of correct maintenance demands operational management and improvement of service. However, we have various limitation matters to reflect the requirements of service base for maintenance accomplishment. Therefore, we need the study of the service based process for solving such a problem. In this paper, we propose a Service based Software Maintenance Process. Proposed process based on ISO12207 standard for software development and maintenance and compares it with the service based representative standards. In a related works, we study activity of $SM^{MM}$, ITSCMM, ITIL and find out activities to be concerned with and compare it with activity of ISO 12207 and distinguish the maintenance process activity of the service base from maintenance activities. And then, we propose a service management stage. It define four activities and eight artifacts. Finally, we validate the result by comparing the proposed process with a general service operational process.

Ontology can be used as a formal and demonstrative knowledgebase that can express the thinking process of human. Software Development Process is a collection of ideal practices and procedural system that is performed by mature organization with high capability. Due to complexity of process, however, Software development Process often results in obstruction of introducing and improving simple process activity. While introducing and improving software development process, application of ontology to complex software development process is more approachable by showing deductive results of relationship between ISO/IEC 15504 and CMMI. In this paper, we demonstrate a methodology that utilizes the improved process database conceptually mapping between ISO/IEC 15504 and CMMI using ontology.

This study validated the strategic alignment approach for e-Transformation of the traditional firm through the case analysis of e-Transformation practices performed in Pulmuone Inc., which had been managed and operated in a traditional mode. The e-Transformation approach identified in this study was focused upon the strategic alignment among 4 domains of business strategy, organizational infrastructure and processes, IT strategy, and IT infrastructure and processes, and was performed in the following process: 1) developing IT strategy to perform business strategy, 2) building IT infrastructure and processes to support IT strategy, and then 3) transforming organizational infrastructure and processes based on IT infrastructure and processes. The theoretical implication of this study is to empirically verify the Strategic Alignment Model hypothesized by Henderson and Venkatraman(1994) through the case analysis on e-Transformation of Korean traditional firm, and the practical contribution is to provide a feasible and effective guideline in carrying out e-Transformation of the typical traditional organization.

As the competition between companies are deepened, the number of companies adopting six sigma principles, which is one of the innovative management strategies, are increasing. According to this trend, the changes in both strategies and methodologies of six sigma are continuous. However, the evaluations and the management principles included in the process after the six sigma applications are insufficient, and the cooperation between the parties in the company is also not enough because the application process of six sigma is too complex and not efficient. In order to solve this problem, a research for developing the methodology which can learn about and do six sigma applications is so necessary, specifically for expanding the six sigma applications and introducing the participation of all company members. The purpose of this study, therefore, was to develop and present more efficient Six Sigma applied process by reducing the existing unnecessary steps in improvement one, by applying the examination method of wasteful elements on the potential factors, through analyzing the Six Sigma DMAIC applied case in the construction industry. The result of those application showed that the detection of potential factors using wasting elements was possible in measurement step and that it was possible for the improved process with reduced steps compared to existing process while to remain the outcomes. It is considered that the performance rate of Six Sigma project will be improved significantly because the reduction in the improvement step does not affect the improvement effect within the whole Six Sigma project.

PLM과 ERP의 정보와 프로세스 통합은 개개인의 영향력을 합친 것보다 더 큰 전체적인 이익을 가져오는 조직 내에서 사용자의 생산성을 증진시킨다. 그러나 이러한 이익을 얻기 위해서는 조직을 통해 정보가 자유롭게 흘러가야 한다. 이러한 통합의 범위를 정의하는 것은 매우 복잡한 일이다. 반드시 포함되어야 할 중요한 요소는 데이터와 프로세스 소유권(ownership), 정보의 주원천 정의, 요구되는 통합 수준, 그리고 제품 설계와 생산 두 영역에 걸쳐있는 프로세스들을 어떻게 관리하느냐이다. 다음에 기고될 원고는 어떻게 PLM과 ERP의 통합이 비즈니스 가치를 극대화 하도록 수행될 수 있을까 하는 중요한 문제를 다루게 될 것이다.

본 논문은 리눅스 커널 운영체제에서 커널 개발자의 실수나 의도하지 않은 오류 및 시스템 오류로 인하여 발생되는 시스템 정지 현상을 줄이기 위한 커널 하드닝 기능을 설계한다. 본 논문에서 제안하는 커널 하드닝 기능은 문제가 발생한 커널 부분을 수행 중인 프로세스에 대한 동작을 정지시키는 기능과 오류가 발생한 코드에 대한 변수 값이나 주소 값이 가진 특정한 값을 복구시키는 기능을 가진다. 커널 하드닝 기능에서 문제가 있는 모든 프로세스를 무조건 복구하는 것이 아니라 복구 가능성을 판별하여, 복구 가능한 프로세스에 대해서만 복구 될 수 있도록 한다. 또한 오류가 발생한 커널 코드에 대해서 복구 가능한 경우에는 ASSERT() 함수에서 복구가 가능하도록 설계하였다.

감리 효과성에 관한 연구가 중요한 이유는 효과적인 감리 수행이 조직의 정보시스템 개발 및 자원관리에 어떠한 영향을 미치는 지를 파악하여, 그 결과 향후 감리 제도의 추진방향 제시 및 역할 정립을 할 수 있기 때문이다. 본 연구는 정보시스템 감리의 효과성을 프로세스 관점에서 정의하고 실제로 이러한 감리가 소프트웨어 프로세스를 향상시키는데 영향을 미치는 지를 살펴본다. 이를 위해 본 연구는 정보시스템 감리를 실시한 공기업을 대상으로 설문 조사를 실시하며 그 효과를 CMM 모델을 이용하여 분석한다.
