Time synchronization is crucial for ensuring the reliable operation of modern economic and social infrastructures. Techniques such as Global Navigation Satellite System (GNSS)-based methods and Two-Way Satellite Time and Frequency Transfer (TWSTFT) play key roles in precise time comparison and synchronization. TWSTFT, in particular, is recognized for its ability to achieve sub-nanosecond accuracy in time transfer, making it indispensable in fields such as satellite navigation. This paper proposes a comprehensive performance evaluation method for TWSTFT modems, emphasizing pre-validation in controlled environments to mitigate operational challenges. Using the proposed evaluation method, the study presents the standard deviation of RTT according to C/N₀ and compares it with the datasheet of a commercial TWSTFT modem. Through this approach, the aim of this study is to enhance the reliability and accuracy of TWSTFT-based time synchronization across diverse applications.

This research focused on the major determinants for the strategic utilization of technology tree as a strategic technology information repository after the adoption of the technology tree in the R&D intensive organization. The study was performed based on both theoretical study and qualitative case study approaches. The result is as follows; for the strategic utilization of the technology tree for the information repository, it should be the market base and be closely related with the technology roadmap. In terms of the needs of times, this study regarding the strategic utilization of technology tree as a strategic technology information repository and as a s strategic supplement for technology roadmap is anticipated to be a good reference for the R&D-oriented organizations and technology-related studies in coming years.

The purpose of this research was to examine the factors that affect colleges that play an important role in technology commercialization as technology provider, and enterprises as technology user engaging in technology transfer commercialization by dividing it into strategic resource factor. And this study was also intended to present a strategic meaning and perspective relative to colleges and enterprises as well. To do this, those factors that have influences on technology transfer commercialization were elicited through investigation of literatures, and classified into strategic resource factors to suit research purpose, and based on these information, research hypothesis and research model were established and designed. Research results improved that some enterprises among benefited from technology transfer.

In this paper, we study the relationship between factors influencing the strategic use of IT and business performance by conducting a survey of small and medium-size enterprises (SMEs). From the results of our survey we came to several conclusions which are presented here. First, IT investment has a significant impact on the strategic use of IT, and the strategic use of IT has a significant impact on business performance. Second, SME investment in IT and strategic use of IT are influenced by both the intensity of competition in the market environment and partnership with other organizations. Third, the support from the management group in SMEs is a core factor for IT investment and strategic use of IT. Finally, for SMEs to use IT strategically and successfully, it is necessary to combine members' participation with a flexible organizational structure and culture.

Government-sponsored Research Institutes (GRIs) have made a great contribution to the development of Korea's Science and Technology (S&T). However, recently, GRIs are facing the challenge of many problems, for instance, absence of reasonable strategies, insufficient resources, and so on. Therefore, many GRIs are required for solving these problems by enhancing their strategic management capabilities. For this purpose, this paper suggests a Strategic Management Audit Model for Korean GRIs. The concept of Strategic Management Audit Model has not been widely adopted in Korean GRIs. In this paper, we suggest GRI-specific Strategic Management Model and apply it to Korea Basic Science Institute (KBSI), which is under the Korea Research Council of Fundamental Science and Technology (KRCF). Based on our strategic management audit, we propose several potential strategies for Korean Basic Research Institutes (KBSI). Our model and its implications will also be helpful for other Korean GRIs.

This study uses theoretical perspectives and models from organizational ecology to examine the dynamics and viability of strategic groups. Integrating the ecological perspective and the contingency theoretical view of strategic management, this study developed propositions demonstrating the impact of environmental density and variation on the effectiveness of strategic groups. Justifications for linking ecological perspectives to strategic management theory are discussed and the importance of the integrative approach to strategic management is highlighted.

Government-sponsored Research Institutes(GRIs) have made a great contribution to the development of Korea's Science and Technology(S&T). However, recently GRIs are facing the challenge of many problems. For instance, absence of reasonable strategies, insufficient resources and so on. Therefore, many GRIs are being asked for solving their problems with successful strategic management. This paper suggests a strategic management model to solve their problems and to cope with the changing S&T environment. In this paper, The strategic management model for GRIs which was thoroughly considered strategic management process suggested to response the need of their change and to perform their strategic management successfully. As a case of GRIs to apply this model, in this paper, Korea Basic Science Institute(KBSI) that is part of the Korea Research Council of Fundamental Science and Technology(KRCF) was analyzed. As a result of analysis with this model which applied to KBSI, various strategies and alternatives were suggested.

The influence factors on the development of information technology(IT) infrastructure for knowledge management(KM) were not empirically investigated and identified. This study empirically examines the relationships among strategic performance measurement systems(SPMS), organizational learning, the strategic alignment of business strategy with information systems(IS) strategy, which is the necessary condition to provide the kinds of knowledge required for the successful realization of business strategy, and the active construction of IT infrastructure for KM. This study demonstrates that SPMS directly affects the organizational learning, with which the members of an organization acquire the types of knowledge about strategic goals or objectives and the ways attaining these goals, and indirectly influences the IS strategic alignment through organizational learning. Thus, the alignment between business strategy and IS strategy can be facilitated and activated by the adoption and implementation of SPMS. According to the results of this study, it is observed that the IS strategic alignment and organizational learning positively affect the activation of the development of KM IT infrastructure in a firm. The results of this study also shows that the construction of KM IT infrastructure, which supports the realization of KM activities, such as knowledge creation, transfer and sharing, can enhance the strategic position of a firm, and the intensified competitiveness of a firm can lead to the improvement of performance.

With limited resources, proper allocation of the national R&D budget is very crucial matter for reinforcing the national competence, and the importance of selecting strategic R&D fields have been increasingly emphasized by technology policy-makers and CTOs. This paper deals with technology relevance/cluster analysis, which measures technological dependency and relevancy among technologies, and how it can be used for selecting the strategic R&D fields especially satisfying SMEs(small and medium enterprises)' specific needs. As a result of this study, technology-product tree composed of 7 major technology fields, 22 clusters, 41 groups, 335 core-need technologies and hundreds of related business items are produced that can be used for designing SMEs' R&D/business portfolio as well as R&D investment decision-making of the Ministry of Small and Medium Business Administration.
