  • Base Isolation system is an effective design strategy that provides a practical substitute for the seismic design of bridge. In this study, the dynamic tests was performed on HDB (Hysteretic Damping Bearing) and Dynapot. Then, the dynamic analysis was carried out for a bridge using the experimental results to estimate the seismic performance of bearings. Analysis for bridge was performed for four types of earthquake loadings. The result of dynamic test and theoretical analysis indicate that the performance of HDB and Dynapot is appropriate for the earthquake loading.

  • For Wi-Fi and IoT wireless systems, high-capacity wireless communication technology is being applied using MIMO OFDM. Because of virtu0al subcarriers in the practical MIMO OFDM system, the pilot subcarriers cannot be spaced equally. Thus, it is difficult to obtain a good mean square error (MSE) performance of the channel estimate. This paper proposes applicable methods and the newly discovered locations of pilot subcarriers in four transmitted antennas resulting in a good MSE performance with proposed optimization algorithms.

  • 예산의 성과계획서는 예산과 성과를 연계하고 성과 중심적인 정책 수행을 위하여 도입되었다. 본 연구는 성과지표가 사업부서별로 어떻게 계획되고 달성되는지 알아보기 위하여 제주특별자치도의 2020년도 농업 분야 예산의 성과계획서를 대상으로 성과지표의 적정성에 대해 검토하였다. 분석결과 정책사업과 목표 간 낮은 연계성, 성과지표에 대한 가중치와 목표치에 대한 근거 불명확, 성과지표의 낮은 도전성 등의 문제점이 있었으며, 다수의 성과지표가 실적 중심의 산출지표였다. 이러한 문제점을 개선하기 위해서는 도전적인 성과지표와 인센티브를 통한 실질적인 성과지표 구축이 필요하다.

  • While many previous studies have emphasized that technological and learning capabilities have an important impact on internationalization, however, there have been few attempts to directly identify the mediating role of innovative performance in the relationship between them. Therefore, we tested the relationships among two organizational capabilities such as technological capability and learning capability, innovative performance and internationalization. Specifically, we explored the impact of two organizational capabilities on innovative performance and the mediating role of innovative performance on internationalization. We tested hypotheses based on 206 survey data of Gwangju and Jeonnam provinces' small and medium-sized enterprises (SMEs). The empirical results showed that both technological capability and learning capability had a significantly positive (+) effect on SMEs' innovation performance, and both technological capability and learning capability had a significantly positive (+) effect on internationalization performance. In addition, it was confirmed that the innovation performance is not only related to the relationship between technological capability and internationalization performance but also acts as a partial mediation role in the relationship between the learning capability and internationalization performance. Based on the results of this study, theoretical and practical implications were provided, and the limitations of this study and future research directions were also discussed.
