2009년 조선왕릉 40기가 제 33차 세계유산위원회에서 유네스코 세계유산으로 등재된 후 한국 정부는 "세계유산 조선왕릉 보존관리 및 활용 기본계획"을 발표하는 등 적극적인 정책을 추진하고 있다. 그럼에도 불구하고 조선왕릉의 활용사업은 아직 시작단계라고 할 수 있으며, 이에 관한 학술적 논의도 거의 없는 실정이다. 본 연구는 2009년부터 2014년까지 6년간 문화재청이 추진한 조선왕릉 활용사업 311개 전 사업을 대상으로 분석하였다. 연구방법으로는 문헌조사와 내용분석법을 사용하였다. 내용분석은 문화재청이 제시했던 문화재 활용유형을 바탕으로 교육적 활용, 관광적 활용, 복합적 활용 및 산업적 활용을 분석틀로 삼았다. 분석결과 조선왕릉 활용사업은 단순한 교육적, 관광적 활용사업에 머물러 있었고, 산업적 활용은 아직 수행되지 못하였다. 또 각 지구관리소별로 유사한 사업들로 구성되어 있고 왕릉별로 독특한 사업이 부족했다. 사업들도 주로 단발성사업이었으며, 투입된 예산도 규모가 작았다. 아울러 정보통신기술(IT)시대에 왕릉현장 위주의 사업에 치중되어 있고 디지털과 온라인을 활용한 융합사업이 미흡하였다. 앞으로 조선왕릉 활용사업에 대한 예산규모의 확대, 왕릉의 독특한 콘텐츠 개발, 산업적 활용사업의 개발, 온라인과 디지털 융합사업 개발, 조선왕릉 활용을 위한 새로운 중장기 계획의 수립 등이 필요하다.

In this paper, a miniaturized directional coupler utilizing lumped element is proposed as a interdigital capacitor. The traditional miniaturization technique of transmission line realized a utilizing MIM(Metal-Insulator-Metal) capacitor on CPW(Coplanar Waveguide). However, we present a simplified design procedure without additional manufacturing process utilizing interdigital capacitor on microstrip with ease of design. The similar characteristics between the conventional directional coupler with ${\lambda}/4$ transmission line and the miniaturized directional coupler with ${\lambda}/8$ transmission line are validated through simulation and measurement results. Miniaturization rate of total size is about 25% while coupled line is about 60%. As a result, this proposed directional coupler can reduce the size of mobile communication system at 2 GHz.

This paper investigates the effect of utilizing vacuum bagging process to enhance the bond behavior between fiber reinforced polymer (FRP) composites and concrete substrate. Sixty specimens were prepared and tested using double-shear bond test. The effect of various parameters such as vacuum, fiber type, and FRP sheet length and width on the bond strength were investigated. The experimental results revealed that utilizing vacuum leads to improve the bond behavior between FRP composites and concrete. Both the ultimate bond forces and the maximum displacements were enhanced when applying the vacuum which leads to reduction in the amount of FRP materials needed to achieve the required bond strength compared with the un-vacuumed specimens. The efficiency of the enhancement in bond behavior due to vacuum highly depends on the fiber type; using carbon fiber showed higher enhancement in the bond strength compared to the glass fiber when vacuum was applied. On the contrary, specimens with glass fiber showed higher enhancement in the maximum slippage compared to specimens with carbon fibers. Utilizing vacuum does not affect the debonding failure modes but lead to increase in the amount of attached concrete on the surface of the debonded FRP sheet.

This study aims to propose a Bayesian approach to consider changes in temperature and vehicle weight as environmental and operational factors for vibration-based long-term bridge health monitoring. The Bayesian approach consists of three steps: step 1 is to identify damage-sensitive features from coefficients of the auto-regressive model utilizing bridge accelerations; step 2 is to perform a regression analysis of the damage-sensitive features to consider environmental and operational changes by means of the Bayesian regression; and step 3 is to make a decision on the bridge health condition based on residuals, differences between the observed and predicted damage-sensitive features, utilizing 95% confidence interval and the Bayesian hypothesis testing. Feasibility of the proposed approach is examined utilizing monitoring data on an in-service bridge recorded over a one-year period. Observations through the study demonstrated that the Bayesian regression considering environmental and operational changes led to more accurate results than that without considering environmental and operational changes. The Bayesian hypothesis testing utilizing data from the healthy bridge, the damage probability of the bridge was judged as no damage.
