IT 프로젝트는 많은 불확실성을 내포하고 있다. 이러한 불확실성은 프로젝트의 성공적인 수행에 좋지 않은 영향을 미치게 된다. 이처럼 악영향을 미치는 근본적인 이유는 프로젝트가 가지고 있는 잠재적 위험(Risk)이 중요한 원인이라 할 수 있다. CMMI-DEV(Capability Maturity Model Integration for Development, version 1.2)모델을 기반으로 IT 프로젝트를 수행하는 많은 조직에서 소프트웨어 개발시 실제 CMMI-DEV 모델을 적용하여 IT 프로젝트의 위험관리를 수행하고 있다. 그러나 대다수 기업에서 위험을 관리하기 위한 프로세스의 범위(영역)를 선정하는 것에는 많은 노력을 기울이지만 단위 프로세스별로 어떠한 방법(How)과 도구 및 관리기법을 사용하여 위험을 정량적으로 관리하고 완화시킬지에 대한 구체화된 노력은 미흡한 것이 사실이다. 본 논문에서는 CMMI-DEV 모델의 RSKM(Risk Management) 프로세스와 PMBOK(Project Management Body of Knowledge, 4th Edition)의 위험관리 지식영역(Knowledge Area)을 프로세스의 지속적인 개선을 위하여 PDCA(Plan-Do-Check-Action) Cycle의 각 단계별 목적에 맞게 통합(Integration)시켜 IT 프로젝트를 위한 개선된 위험관리 프로세스를 제안하였다. 제안 프로세스의 개선효과를 검증하고 분석하기 위하여 측정지표를 제시하였으며, 개선 프로세스의 적용 전후 결과를 정량적으로 비교 및 분석함으로써 개선효과를 도출하였다.

The research model was established by exploring exogenous variables based on the rational behavior theory and applying the Technology Acceptance Model (TAM). The acceptance of MSI provided to investors in the stock market was found to be influenced by the exogenous variables presented in this study. The results of causal analysis are as follows. First, self-efficacy, investment opportunities, Innovativeness, and perceived cost significantly affect perceived ease of use. Second, Diversity of services and perceived benefits have a statistically significant impact on perceived usefulness. Third, Perceived ease of use and perceived usefulness have a statistically significant effect on attitude to use. Fourth, Attitude to use statistically significantly influences the intention to use, and the investment opportunities as an independent variable affects the intention to use. Fifth, the intention to use statistically significantly affects the final dependent variable, the intention to use continuously. The mediating effect between the independent and dependent variables of the research model is as follows. First, The indirect effect on the causal route from diversity of services to continuous use intention was 0.1491, which was statistically significant at the significance level of 1%. Second, The indirect effect on the causal route from perceived benefit to continuous use intention was 0.1281, which was statistically significant at the significance level of 1%. The results of the multi-group analysis are as follows. First, for groups with and without stock investment experience, multi-group analysis was not possible because the measurement uniformity between the two groups was not secured. Second, the analysis result of the difference in the effect of independent variables of male and female groups on the intention to use continuously, where measurement uniformity was secured between the two groups, In the causal route from usage attitude to usage intention, women are higher than men. And in the causal route from use intention to continuous use intention, males were very high and showed statistically significant difference at significance level 5%.

In spite of the transitional changes in the shoe industry in Busan area, regular academic studies on the management plan to improve the practical competitiveness of footwear industry focused in the materials, bio-dynamics, components, and designs, etc. in the engineering viewpoint are very rare. Many reports of policies were published from late 190's to 2000's but they were limited to the identification of practical situations and the measures for strategic alternatives and were not developed to be the academic studies to improve the competitiveness in terms of management control. It is intended to seek for the measures to be reviewed as the alternatives to improve the self-competitiveness of footwear companies by approaching the problems limited to such specific area in the viewpoint of management control. The core of this study is to provide the alternative plans for expansion of the industrial foundation by seeking for the measures to improve competitiveness with application of knowledge management as an alternative for improvement of not transient but sustainable industrial competitiveness, in order to help the export of shoes from Busan area which has been rapidly increased since the Korea-USA FTA and Korea-EU FTA. In such viewpoint, in the study, a questionnaire survey was performed related with the issues of Busan's footwear industry and the plan to implement knowledge management was discussed for improvement of the competitiveness of footwear industry based on the result of such questionnaire survey. As most of studies and directions have been focused in functional shoes, designs, materials, and components, etc., which are related with the properties of human dynamics, as the alternatives for improvement of the footwear industry of Busan area and did not suggest the measures to make basic changes in the management of companies, the implementation of knowledge management was emphasized in order to seek for the direction of such plan. The purpose of this study is to suggest an alternative for construction of industrial eco-system for high added value by seeking for the probability of knowledge management for conversion of footwear industry into knowledge industry. In order to accomplish the effect of increased export as the result of FTA, current management method of footwear companies is limited and the effect of FTA should be maximized by improving the competitiveness with implementation of knowledge management methods.

The Korean government continuously increases the R&D investment in order to pursue an economic growth through technological innovation. Hence, the intensity of governmental R&D has increased rapidly. However, the whole amount of the R&D investment is still small compared to developed countries. And the type of R&D policies is more and more changing from the catch-up model to the technology-driven model. Therefore, there is a growing interest in the efficiency of public R&D investment. Hence, many studies on the efficiency of R&D investment have been researched. This study estimated the efficiency of governmental R&D programs considering the technological outcomes, e.g. theses, patents and so on, using DEA(Data Envelopment Analysis) with data of S&T investment and outcomes from NTIS(National S&D Information Service). In addition, we used the Mann-Whitney Test to investigate the characteristics of governmental R&D investment.
