Fabrication and investigation of composite made of graphite, SiC, mullite and aluminum as the additive are the aim of this project. Aluminum acts as an anti-oxidant. SiC is a non-metallic anti-oxidant that increases composite strength. Different compositions with influent percents of aluminum have been selected to determine product specifications by XRD, SEM and STA methods. Results show that the composition of 40wt% graphite-20% SiC- 20% mullite-20% aluminum is a more robust and occurs at elevated temperatures than other graphite combustion composites.

Large-scaled hospital information system projects are often delayed than originally planned. Regarding project management, it is necessary to examine main factors triggering the schedule delay and to analyze the causality of such delay. This study tries to find the delay factors and causal relationship between them based on the case of the hospital information system development project by using the grounded theory method. It turned out that 'unrealistic scheduling' affects overall schedule delays like domino phenomenon, and 'poor analysis of existing systems' leads to poor quality of work analysis while 'poor subsystem integrated interface' triggers poor design quality. This study found out the factors affecting the delay of a project, analyzing cause-and-effect relationships between them in the academic side. From the practical view, it shows a solution to minimize delays in the project schedule for each of SI companies, hospitals and project managers.

Previously, we have identified 14 putative downstream target genes of Hoxc8 homeoprotein in F9 murine embryonic teratocarcinoma cells through proteomics analysis. Among those, we tested a possibility of a DNA-k type molecular chaperone, Grp78, as a direct downstream target of Hoxc8, by cloning a 2.4 kb upstream region of murine Grp78 into a reporter plasmid and by testing if Hoxc8 can regulate its expression. We observed that Hoxc8 proteins could transactivate the reporter gene, which was affected by small interference RNAs (siRNAs) against to Hoxc8, suggesting that Grp78 is a novel downstream target of Hoxc8 in vivo.

The chronic problems of Information System Outsourcing Development Project include frequent changes in the participants and their roles, and the evasion of project participation, which exert unfavorable influence to the outcome of the project. Such problems are due, in large part, to the low level of project participants' satisfaction in the project. However, little is known about the factors that influence project participants' satisfaction in the project development. This research identifies six potential factors such as project commitment, workload, control, communication within the organization, inter-organization communication, and system development methodology based on PMI(Project Management Institute) and empirically examines their efficacy in explaining the level of participants' satisfaction in the IS development projects based on data from 390 participants in 66 projects. The results indicate that the six factors are strong determinants of participants' satisfaction in system development projects. In other words, the level of satisfaction among project participants overall are largely influenced by project commitment and control, communication, project methodology. Especially, the results reveal that the level of satisfaction among participants from the vendor decreased largely by unrealistic project commitment, frequent changes in project planning and unreasonable control rather than by a significant amount of workload. In conclusion, there need to be a rational approach and solution based on the six factors presented in this research in order to increase participation satisfaction level of the project participants and ultimately enhance project outcome.

Korea has relied on top down development method, in which companies, research and education institutions move into the industrial complexes established by the government. However, to improve local competitiveness, the paradigm is shifting from the government initiated industrial complex to the clusters based on the cooperative network of the region. Representative case is 'Samcheok-si Fire & Emergency industry cluster construction project' that begun in 2007. AHP technique analysis results on first-stage showed that priority was on policy and network elements, and the results of second-stage analysis show that priority was on Policy incentives to internationalize the cluster and strengthen link,. Cluster branding, Sharing of organizational culture to cope with changes in environment, Creation of group learning culture. The subject of this research is limited to Samcheok-si's the Fire and Emergency Industry cluster formation project. Therefore, the research area and standard should be expanded to increase generality in further researches.

In order to accomplish large-size information systems successfully, one of the most improtant factor is the system integration(SI) of individual software projects which consist of the systems. A developer of each project should consider aspects of SI through the development cycle, and a manager of the entire system should manage, control, and evaluate each from a SI point of view. In this research, management models for the system managers, development models for the developers of unit projects, and standardized output documents for the management and evaluation purpose are presented based on the SI concepts.

Due to the global business environments and severe competitions, SMEs have carried out IS projects for their competitive advantages. However, numerous organizations have faced with difficulties in the IS project management such as large amounts of IT expenses and uncertainties in project implementations. Thus, this study is intended to discover critical risk factors in the IS project management. To achieve this research goal, we have mailed questionnaires to SMEs and SI companies that experienced IS project failures and 63 usual data were collected. The result of analysis with step wise regression showed that 6 factors are related with IS project failures. The study contributes to the literature in two ways. First, this paper empirically identifies IS risk factors for SME manufactures. Second, this research result can be utilized as a checklist for the successful IS implementations. Limitations and future research topics are also discussed.

Regarding project management, many organizations have developed and distributed general project management knowledge systems, and application fields use the knowledge systems to apply the process suitable for characteristics of a project. This study suggests project management process models to apply to system integration projects. This system integration project management process model is composed of six top processes of initiation, preparation for contract, planning, implementation management, coordination and control, and termination and transfer. The five processes are re-divided into 25 bottom processes. These processes are expressed as input, control, output, and mechanism by using the IDEF0 model. For this model development, it has chosen the items which constituted a process through a questionnaire of experts.

Despite rapid growth of the global SW market, the Korean market still has a long way to go to impact global power nations. What is the reason that holds back of the No. 1 high-speed Internet country in terms of SW development? It is lack of the foundation for development of the Korean SW industry. In this context, the Korean government declared SW-oriented society and developed polices for each sector; Regarding movement that tries to apply the SW partitioning order institution in public sector to IT projects, this research aims to study SI project problems expected when conducting the SW partitioning order institution and improvements focusing on the public sector that accounts for about 30% of the entire SW industry. SW partitioning order institution is divided into planning-design and development-realization stages, which may cause problems when it is applied to SI projects. As such, the study analyzed SI projects and separate and partitioning order, exemplary cases and examples of industrial projects related to partitioning order, and drew improvement measures from institutional, technological and managerial viewpoints. The research aims to help people involved in IT projects sell SW at proper prices and improve the environment, and presents directions to create a system that strengthens competitiveness of the SW industry and SI projects by providing solutions to problems that suppliers and demanders should recognize before implementing the SW partitioning order institution.
