The purpose of this study is to examine how two factors among various affecting factors of technological innovation, i.e. sectoral system of innovation and R&D support service, were actually applied in the case of NUC Electronics. This company has achieved high level of innovation performance through change of injection port and improvement of extracting rate. This was possible because each component of sectoral system of innovation system was matched with the innovation activity. The improvement of the performance in NUC Electronics was attributable to its own innovation efforts and R&D support service of government research institute. In the process of technological innovation, the company could receive high-level services in areas such as product design and virtual experiments that companies can not solve themselves. It can be said that the role of government and public institutions to support the shortage of SMEs was important. In terms of each component of sectoral system of innovation, we found that there were many opportunities of new technology; sustainability was low; imitation was easy; appropriability was low but it has dualily; accumulation of technology was relatively high, availability of external knowledge was high. At the same time, both of the company and the network played an important role, and market conditions were very favorable. In terms of R&D support services, it is a direct effect that a great deal of time and cost savings have been achieved through virtual experiments on the material and shape of the screw. As an indirect effect, the core competence of the company has been greatly strengthened by utilizing the momentum of technology development through external support, hence the company could establish the structure of virtuous circle of innovation.

최근 클라우드 기술이 확산되면서 여러 기업이 자신만의 클라우드를 다양하게 제공하고 있으며 세계 각지에 흩어져 있는 다양한 클라우드 공급자들과 여러 프라이빗 클라우드를 연결하여 하나의 서비스를 제공하는 클라우드 서비스 브로커리지(Cloud Services Brokerage) 기술이 등장하게 되었다. 하지만 현재의 CSB 기술은 가상 자원 관리, 가상 머신 라이프 사이클 관리에 초점이 맞추어져 있으며 CSB에서 제공되는 모니터링 요소는 사용자의 복잡한 요구를 만족하기에는 부족한 실정이다. 또한 추가 모니터링 도구를 사용하는 경우도 CSB의 데이터와의 일관성을 만족하지 않는 문제가 있다. 따라서 본 논문에서는 이종 CSB와 연동이 가능한 실시간 모니터링 시스템을 제안한다. 본 논문에서 제안하는 모니터링 기술은 Scalr 및 CompatibleOne을 사용하여 주기적으로 메타데이터 동기화를 진행하며 데이터 일관성을 충족시키고 다양한 모니터링 데이터를 실시간으로 수집하여 사용자에게 제공한다.

In Korea, we witness vivid evidences of changing trend in communication that insist the emergence of new networking architecture. To accommodate the changing trend and to hold current strong position in global IT industry, Korea have launched broadband convergence network (BcN) initiative. BcN vision for Korea is to be the first in the world to realize converged network infrastructure and ubiquitous service environment. In this paper, we have introduced the concept and the vision of BcN with a viewpoint of a new paradigm to prepare future-proof communication environment. And then, we have disclosed BcN research and development (R&D) activities including R&D philosophy, R&D phases, and key technologies required. Also, we have discussed current development issues in three technology branches including service and control technology, unified transport technology, and next-generation access technology.

This paper presents the evaluation of LPG (Liquefied petroleum gas) regulators for home use. For the evaluation, several properties of the regulators were experimentally analyzed, such as the operation of safety device, the adjusting and lock-up pressure, the adjusting spring and the diaphragm, with respect to the used time of the regulators. Experimental results showed that the initial operation performances of regulators were degraded with increase of the service time and also showed that the degradation of the performance and material property could become serious after about six-year-use of the regulators.

There are a great number of Internet-connected devices and their information can be acquired through an Internet-wide scanning tool. By associating device information with publicly known security vulnerabilities, security experts are able to determine whether a particular device is vulnerable. Currently, the identification of the device information and its related vulnerabilities is manually carried out. It is necessary to automate the process to identify a huge number of Internet-connected devices in order to analyze more than one hundred thousand security vulnerabilities. In this paper, we propose a method of automatically generating device information in the Common Platform Enumeration (CPE) format from banner text to discover potentially weak devices having the Common Vulnerabilities Exposures (CVE) vulnerability. We demonstrated that our proposed method can distinguish as much adequate CPE information as possible in the service banner.

The educational method of physical computing, where students can experience software programming principles and practices while making concrete objects beyond outputs residing just inside of computer monitors, are drawing attentions. This current research sought an instructional method for pre-service teachers that they can experience 3D printing and modeling and at the same time they can understand programming principles in the 3D modeling processes. To achieve this aim, the TinkerCAD $Codeblocks^{(R)}$ was analyzed based on the computational thinking framework and a course utilizing the $Codeblocks^{(R)}$ to 3D modeling was devised. The designed class was applied to pre-service teachers and the students' perceptions of the class were collected by using a semi-structured survey. This study provides implications to software education for pre-service teachers as an instructional case that 3D printing is used to connecting computational thinking skills.

Since R&D (Research and Development) of small companies is becoming more and more important, and government R&D grants are still increasing. This study aims to investigate the factors influencing R&D performance of small companies and necessary capabilities of them. Based on empirical study of 3,636 small companies which participated and completed government R&D grant project, technology innovation capability and technology commercializing capability of small companies are positively related with organizational competences, with moderating effects of entrepreneurship. In addition, their R&D capabilities are not significantly related with R&D commercializing performance directly, but mediated with organizational competences. The results of study suggest implications of measuring the R&D performance of small companies and government support policy with the importance of organizational competences as an intermediate variable of R&D performances.

Background: Although the importance of pharmaceutical care service has been growing to meet the needs of customers with the improvement of clinical and humanistic outcomes, there was not a systematic strategy to promote research in Korea. The aim of this study was to suggest the core agendas for pharmaceutical care services research and development (R&D) considering priorities. Methods: Based on desk researches, we developed R&D agendas for the needs of improving pharmaceutical care services in the area of institution, community, and public health. To determine the priority of agendas in developing pharmaceutical care service, analytic hierarchy process (AHP) analysis was performed by the 14 experts. Criteria and subcriteria were assessed for significance by pairwise comparisons. Then, agendas were evaluated for importance according to each subcriteria, and rank ordered considering the weight calculated by multiplying the importance scores of the criteria and the subcriteria. Results: We derived 25 agendas including 13 for institutional pharmaceutical care service, 8 for community pharmaceutical care service, and 4 for public-health related pharmaceutical care service. AHP model was constructed based on 4 criteria and 8 subcriteria by a hierarchical structure. From the AHP survey, the 'Development of pharmaceutical care service for metabolic and chronic disease' agenda accounted for the highest priority. Conclusion: We have developed the R&D agendas of the pharmaceutical care service which should be promoted. The results should be utilized by the government to nationally support the development of the standards and relevant regulations related to pharmaceutical care services in Korea.
