Summary: This study examines how information from the construction stage can enhance the reliability estimate for dikes during flood conditions, showing that reliability can significantly increase, especially for dikes on soft soil blankets. The main factors influencing the degree of reliability update were ground conditions and the criticality of slope stability during construction.

Summary: The rapid development of information technology has made security a crucial factor. This study addresses the challenges of quality and capacity in hiding data within video files by exploring histograms and prediction errors. Experimental results show that this method outperforms other algorithms in terms of peak signal to noise ratio (PSNR) and can hold more bits without sacrificing stego quality. Additionally, this approach is reversible, allowing for extraction of both cover and secret from the stego file.

Summary: This paper proposes a framework for supplying public services based on the TOD concept and GIS analysis technique, finding vulnerable residential buildings with poor environment and selecting old commercial buildings as candidate buildings for public services. The proposed decision-making methods can improve the environment of vulnerable residential buildings by selecting the locations of public services using computational analysis with GIS.

Summary: The use of cloud platforms in scientific workflows presents challenges for users in selecting resources efficiently. To address this issue, a provisioning service called CRCPs is proposed to predict resource and cost, allowing users to optimize performance and budget before workflow execution. The results demonstrate the adequacy of CRCPs in estimating and optimizing resources, time, and cost.

Summary: Electrical contractors often face challenges when subcontracting with general contractors, such as limited construction sites, schedule interference, and inefficient communication. This study compared successful and failed electrical construction projects, focusing on cost and schedule performance. The findings showed that most task strings had a positive impact on cost success, while only subcontractor management had a positive impact on schedule success.

Summary: The Korea Meteorological Administration (KMA) developed automatic focal mechanisms (AFMs) based on the time domain moment tensor inversion method to provide detailed hypocenter information after the earthquake early warning (EEW) service. AFMs automatically collect and reform waveform data using information from EEW. By reducing low variance reduction data, an additional module of iterative inversion was proposed, resulting in increased accuracy of the focal mechanisms.

Summary: This paper introduces a low-cost mobile augmented reality service prototype, which demonstrates its usability for pipe maintenance by supporting inspection, workflow management, data reduction, and augmented reality. User feedback from organizations in the UK and South Korea also indicates that integrating the augmented reality service with building automation tools enhances decision-making for onsite operations. The paper highlights the need for developing low-cost digital solutions to foster the digitalization of construction organizations with limited budgets.

Summary: This study examines the impact of venture capitalists' monitoring on mitigating cost stickiness in an IPO setting, which can result from overly optimistic issuers. Using data from the KOSDAQ market in Korea, we find that companies managed by optimistic issuers experience cost stickiness after the IPO. However, the presence and ownership percentage of long-term venture capitalists help reduce this cost stickiness. Our findings highlight the role of VC monitoring in curbing suboptimal decisions by issuers in emerging IPO markets.
