To have global competitiveness in newly growing industry, good quality R&D's in convergence technology arerequired. Korean government also started to emphasize the importance of convergence technology as a new engine of growth for the future development. Since 2008, worldwide energy crisis and concerns on low carbon green growth made people focus on the convergence between information technology (IT) and energy technology (ET). However, the R&D performance comparison among the convergence technologies is not well explored so far. Therefore, this study uses Korea's patent citation database to measure the R&D performance of convergence technologies. We adopt technology development cycle, technology spillover analysis, and technology diffusion analysis to see the knowledge flow from R&D industry to others. We find that IT_ET convergence technology generally shows higher R&D performance than other convergence technologies. Contrary to public belief, convergence R&D by big companies has relatively low performance especially measures in technology spillover and technology diffusion. This implies that they might concentrate on delicate Fuel Cell Energy/Environment Technology (FEIT) or Nano Environment/Energy Information Technology (NEIT) rather than general energy information technologies. We also find that Korea's chemical industry may play a crucial role for the growth of other convergence technologies.

This paper summarizes the results of the government R&D funding for ICT SMEs over the past five years, and compares the differences in R&D performance of the government funding methods (grant and loan). Two major ICT SMEs funding programs were examined, and the data used in the comparison were based on the performance analysis report published by the MSIP (Ministry of Science, ICT and Future Planning) every year. Considering that the projects' conductors were SMEs and that the R&D stages were in development research, the comparison categories were the number of patents and employment (or jobs) positions created, and commercialization success rate and its sales. Comparative analysis results proved that the SME R&D programs were funded with grants had excellent technological achievements in terms of the number of patent applications and registrations. On the other hand, SME R&D programs that were funded by the government loans had relatively higher economic and social achievements, such as employment effects and commercialization sales. However, it was difficult to come to a comparative conclusion on the category of commercialization success rate between the two programs. As the result, this paper provides suggestions for the direction and policy of the government financial support for ICT SME R&D.

This study explores the application of the analytic network process (ANP) approach for the evaluation of R&D projects with heterogeneous objectives. The ANP model in this study produced the final priorities of projects with respect to several performance measures when there are interdependencies between research objectives and performance measures. The paper provides value to practitioners by providing a generic model for R&D project evaluation. The ANP approach is tested against empirical data drawn from fourteen R&D projects under six different objective programs sponsored by the Korean government.

When replacing hardware due to obsolescence, discontinuation, and expansion of software-equipped electronic equipment, software changes are required in the past, but if virtualization technology is applied, it can be applied without software changes. In this regard, we studied in order to apply virtualization technology in the development of naval multi-function radar signal processing, we studied hardware and OS independency for Docker and performance comparison between Docker and virtual machine. As a result, it was confirmed that hardware and OS independence exist when using Docker and that high-speed processing is possible compared to the virtual machine.

The present study introduces a comparison between 3D R-tree and octree which are noticeable candidates to index large point clouds gathered from a 3D terrestrial laser scanner. A query method, which is to find neighboring points within given distances, was devised for the comparison, and time lapses for the query along with memory usages were checked. From tests conducted on point clouds scanned from a building and a stone pagoda, it was shown that octree has the advantage of fast generation and query while 3D R-tree is more memory-efficient. Both index and leaf capacity were revealed to be ruling factors to get the best performance of 3D R-tree, while the number of level was of oetree.

This paper presents the performance investigation and design technology of a Line Start-up Permanent Magnet Synchronous Motor (LSPMSM) with super premium efficiency, including a design consideration and evaluation for motor start-up, key performance, and advanced finite element analysis FEA) for the design, improvement and verification, prototype build and test, design and test data comparison with a $Premium^{(R)}$ Efficient Induction Motor (PEIM). To assess the design technology, the LSPMSM prototype was built amended from a PEIM with the same frame, stator punching and rated output. Based on the prototype test, two novel design improvements and analyses have been done to eliminate noise and vibration. Additionally, the comparisons with the PEIM on the power factor, efficiency, frame size and active material consumption indicated that a significant performance improvement and active material cost reduction can be achieved by the LSPMSM.

This paper proposes various policies for improving the process of performance analysis on R&D expenditure of the public funds in the Korean ICT industry. In order to do so, this paper figures out the present issues relating to performance indicators, methodologies for performance evaluation, release and comparison of evaluation results, follow-up study, integrated management system for performance analysis in ICT industry. In this paper, we suggest some new policies such as consulting an expert for improving performance indicators, maintaining the pre-determined performance indicators, introducing the qualitative performance indicators for measuring effectiveness, adopting the new methodologies reflecting R&D characteristics, introducing the new performance index for comparing annual performance, requiring follow-up study for major ICT R&D, introducing the independent and temporary organization for R&D performance analysis in ICT industry. In conclusion, these new policies will raise effectiveness and efficiency of the government R&D expenditure in ICT industry as well as strengthen the industry competitiveness.

National research and development(R&D) project plays an important role in the economic growth of a country as well as a company. This article aim to examine the development of the performance evaluation framework for assessing the contribution of national research and development(R&D) program to productivity growth. The main idea of this paper begins with the employment of between-group analysis for evaluating the returns to R&D. The method of this study is based on the comparison of productivity growth between different groups with time series data, not cross-sectional approach with one period. In these regards, backward effect and forward effect are operationally defined as a measurement for contributions of R&D in this study. The results of analysis gives that the outcomes of between-group analysis shows the lower performance of R&D compared to the within-group analysis. while the difference was not especially evident with the case of operating profit variable, but sales variable.

Nonvolatile FRAMs with a design rule of 0.18 ${\mu}m$ were developed for the high performance smart card. A 1Mb FRAM was embedded in place of an EEPROM and a 64Kb FRAM was embedded in place of a. SRAM. It was confirmed that the FRAMs performed the roles of the EEPROM and SRAM successfully using the asynchronous write/read operation method and the one time programming (OTP) scheme. The cycle time of the FRAM was 10 MHz, which remarkably improved the write performance of the smart card in comparison with that of the conventional smart card with an EEPROM. Additionally, a simple and smart bit-line reference scheme for the future FRAM device having a 1T1C cell type was proposed.

The 4th Industrial Revolution is a revolutionary change through intelligence, big fusion and personalization, and the importance of sensor technology that is the basis of core technology is emerging. This study empirically analyzes the derivation of national strategy for R&D of sensor technology, and draws out the effect of technology internalization effort through strategic R&D activities on technical performance and further on national economy. The research and development results are calculated for each type of technology internalization, and the results of the research and development are verified to establish a structure that contributes to the national economic performance. As a national technology internalization strategy, considering its own R&D investment and joint research and development, we examine the impact of each factor on patents and GDP, focusing on causality and ripple effects. For causality analysis, Grandeur causality analysis shows that R&D investment and joint research and development in all countries have mutual causal relationship with GDP. The implications are as follows. First, it is necessary to establish the policy of national economic development through the internalization of technology and knowledge. Second, it is necessary to establish policies according to the type of knowledge internalization. Third, it will be necessary to create an ecosystem environment based on a virtuous relationship between knowledge internalization and national technology and economic development.
