In modern times, with advances in semiconductor technology such as electronic devices, the need to improve the quality of onboard equipment with advanced electronic parts in automobiles, drones, airplanes, projectiles, and various fields, and reduce the impact of various disturbances on onboard equipment is becoming more important. Vibration control through hardware must be determined to prevent damage and improve quality to equipment operating in various environments such as automobiles, drones, airplanes, and projectiles. This study focuses on the study of vibration damping systems to protect mounted equipment from various disturbances and improve stability. Dynamic characteristics analysis, including compressive stiffness, damping rate, and frequency response, and vibration characteristics in the frequency domain of rubber dampers were identified through FEM analysis to identify the characteristics of rubber dampers. Through these findings, we would like to present the criteria for selecting a suitable rubber damper under various disturbance conditions.

This study aimed to translate and validate the Meta-cognition about Social Media Use Scale in Korean(MSMUS-K). For this purpose, the 12 items of the original scale were translated and reverse-translated after obtaining consent from the original author, and the final items were finalized through expert judgment. A survey was conducted with 404 consenting adult participants in Korea, and data from 367 individuals(156 males, 211 females), excluding unreliable responses, were analyzed. Exploratory and confirmatory factor analyses were conducted and the results indicate that all items had good fit, and the scale consisted of two subfactors as the original scale, negative metacognition and positive metacognition. To assess the construct validity, correlations were analyzed between MSMUS-K and the SNS Addiction Proneness Scale, the Smartphone Addiction Proneness Scale for Adults, the Korean version of the Center for Epidemiological Studies-Depression Scale, and the Brief Self Control Scale. MSMUS-K showed significant correlations with all these scales. Finally, the internal consistency reliability of MSMUS-K was adequate. These results indicate that MSMUS-K is reliable and valid scale. Based on these results, the study discussed the significance and limitations of the research, and suggestions for future research.
무선인터넷 상에서 Embedded Linux를 이용한 WPKI의 설계 및 구현

무선 단말기 기반 기술의 발달에 따라 많은 이용자들이 있고 일반 PC에서만 사용되던 기술들을 무선의 시간 공간 제약이 없는 작업환경에서 이용하고자 하는 욕구의 증가로 점차 확산되고 있다. 이에 발 맞추어 2003년 중반 4개 은행이 PC에서 사용되던 인터넷 뱅킹을 무선 단말기를 이용하는 서비스로 확장 시행하였다. 현재 단말기는 PPC(Pocket PC)와 Palm 사용되는 운영체제로는Window CE와 Palm을 운영체제로 하는 기기에서 서비스를 제공하고 있어, 위의 단말기를 제외한 이 기종에서 서비스 사용이 어렵다. 더 많은 사용자들의 사용을 위해서는 다양한 단말기에서의 사용이 가능하여야 하기 때문에 이 논문에서는 Linux를 OS로 하는 단말기에서의 WPKI인증 기술을 구현한다. Because the Internet diffusion has been increased, the service that used at the offline has been applied to the online, the saving time and portability has been emphasized, and the service has been increased from the wire to the wireless by the development of the mobile communication technology. There are a Pocket PC, Palm and so forth as devices that are used for it and the services are already used. However, because it is used at only limited operating systems like PCs have, there is the restriction to use for much more users. In order to allow various devices used by much more people the access services, the WPKI authentication should be implemented for devices using Linux OS.
