Our government has concentrated its policy capabilities on Software industry in order to realize software-centric society. Through such efforts, software industry has developed continuously. As well, it has been a high-valued industry by the association with other various industries, so its importance has been great and its market has grown explosively. However, owing to the hasty support policies focused on software industry, various problems and adverse effects, such as the decline of construction quality due to the confusion of business operator selection and the business area conflict, has occurred. Therefore, in this thesis, I will find the problem and its cause about software support policies and relevant laws according to rapid market change, and will suggest the improvement plan about them. So, I intend to minimize the problems associated with the confusion of business operator selection, through the business area clarification(software industry and information communication construction industry) about complex ICT industry.

Recently, interest in alternative energy has been increasing to reduce greenhouse gas emissions and fossil fuel consumption in accordance with the United Nations Framework Convention on Climate Change(UNFCCC). Accordingly, there is a need to use waste heat that unused throughout industrial systems for lowering the concentration of energy on fossil fuels. In particular, government support projects for the energy recycling of agriculture and fisheries such as cultivation of tropical crops and aquaculture are being actively carried out by utilizing waste heat and thermal effluents caused from large-scale industrial complexes including power plants. The study was conducted on supplier (power plant), consumer (farmer) and stakeholders (constructor and local governments) of domestic demonstration areas using waste heat that is abandoned from the power plant in the form of thermal effluents. It investigated the overall improvement and feasibility of government funded projects through field interviews and questionnaire-type surveys. The results of this study are expected to provide basic directions for the operation of the project in terms of nationwide expansion and diffusion of the heat source supply project at horticultural greenhouse by utilizing the thermal effluents from power plant.

The enterprise resource planning (ERP) system is a standardized and advanced business process that many companies are implementing now-a-days through customization. However, it affects the efficiency of operations as these customizations are based on uniqueness. In this study, we analyzed the impact of customized modules and processing time on customer service request (CSR), by utilizing the stacked CSR data during the construction and operation of ERP, focusing on small and medium-sized enterprises (SMEs). As a result, a positive correlation was found between unit companies and the length of ERP implementation; ERP modules and the length of ERP implementation; ERP modules and unit companies; and the type of ERP implementation and ERP module. In terms of CSR, a comparison of CSR processing time of CBO (customized business object) module and STD (standard) module revealed that while the five modules did not display statistically significant differences, one module demonstrated a statistically very significant difference. In sum, the analysis indicates that the CBO-type CSR and its processing cost are higher than those of STD-type CSR. These results indicate that companies planning to implement an ERP system should consider the ERP module and their customization ratio and level. It not only gives the theoretical validity that should be considered as an indicator for decision making when ERP is constructed, but also its implications on the impact of processing time suggesting that the maintenance costs and project scheduling of ERP software must also be considered. This study is the first to present the degree of impact on the operation and maintenance of customized modules based on actual data and can provide a theoretical basis for applying SW change ratio in the cost estimation of ERP system maintenance.

Although the related regulations or guidelines are not specified in the defense weapon system R&D process, R&D authorities frequently encounter problems that require rational decision-making. If the rational process is not applied in the matter of alternative choice, the project could be disrupted, which can result in longer project periods or more resource provision. In particular, a variety of decision-making methods are needed for test&evaluation of missile R&D. The issue of selecting a test site is one of the representative decision-making problems. If it is needed to determine the priority of multiple sites, Delphi Method and Analytic Hierarchy Process(AHP) will be applied. However, if the input of cost is to be considered, Data Envelopment Analysis(DEA) is more valuable to solve the problem. This paper proposes a solution to handle quantitatively various decision-making problems that can occur in missile flight test, and shows how DEA is applied through a simulated case study of selecting a foreign test site.

OASIS(Online Archiving & Searching Internet Sources) is a web archiving project of the National Library of Korea started in 2004 to systematically collect, manage, and preserve online digital information resources. In this study, the following problems were derived by analyzing the access log of the OASIS website and conducting a user survey. First, people's awareness of the OASIS project was very low, and there were many first-time visitors to the website. Second, active promotion and service reorganization to improve the use of OASIS was insufficient. The study suggested that the improvement point of this was to strengthen its own direct promotion and indirect promotion in connection with other agencies. In addition, it was proposed to enhance the service through user-customized services and to reinforce content that induces interest and fun.

The Southeastern economic zone was centered on small and medium-sized manufacturing, but industrial changes and corona 19 caused the local economic downturn. This study presented the difficulties of companies related to the aviation specialization industry and suggested ways to revitalize the local economy in order to revitalize the local economy in the southeast region. First, aeronautical specialized parts companies need various support to improve the structural problems of passive industries. Second, the industry needs a systematic education system that develops products and technologies that meet international standards and conducts international certification education to support stable supply and demand of human resources by cultivating professional manpower for systematic project performance. Third, the industry needs financial and administrative support from the government to develop technologies and products that meet high standardization standards. In addition, it is necessary to provide support to systematically improve the limitations and difficulties of companies, such as finding and expanding customers of small and medium-sized companies and supporting investment for cost reduction.

Recently, the Ministry of Strategy and Finance announced a plan to reduce the proportion of economic evaluation in non-metropolitan areas and strengthen balanced development evaluation through the reorganization of the preliminary feasibility study system. In addition, the social value of the quality of life, such as job, environment, and safety, which may be affected by the implementation of transportation facility investment projects, was reflected as the main item of policy evaluation. In this study, the ripple effect of the project in terms of social value was reviewed for the Gangil-Chuncheon. The effect of highway opening was investigated by reviewing the feasibility report, post-evaluation report, and statistical indicators. Recently, the Gangil-Chuncheon highway is getting used by around 110,000 people per day. The number of tourists in Chuncheon rapidly has increased from 5 million a year to more than 11 million now. In addition, it was confirmed to produce effects such as population migration, net inflow and land price increase, improvement of living convenience, and expansion of emergency medical care. Although this ripple effect was influenced by various socio-economic factors as well as the opening of the highway, it is clear that it is difficult to occur without the opening of the highway. It is judged that the evaluation of indirect benefits and social values due to the opening of the highway can be quantified through continuous research and data construction. Post-evaluation of construction works, including project efficiency evaluation and ripple effect evaluation, is performed for construction works with a construction cost of more than 50 billion won. In the future, we will continuously improve the evaluation system in order to evaluate the indirect benefits and social values of public investment projects.
