본 연구는 BIM을 활용한 그래프 기반의 동선 표현과 분석 접근 방법 제안을 목적으로 한다. 접근 방법의 제안을 위해 건물 동선 관련 요구사항 파악과 공간 네트워크, BIM에 관한 선행연구를 분석하였다. 또한, 본 연구는 선행연구인 UCN(Universal Circulation Network)을 기반으로 연구를 진행하였으며, 본 연구를 통해 UCN에 추가적으로 고려해야 할 사항을 파악하고 이를 확장하였다. 본 연구에서는 UCN을 기반으로 두 가지 관점에서 동선의 표현과 분석 접근 방법을 제안하고자한다: 1) UCN의 그래프 기반 동선 분석의 주요 요소를 파악한다, 2) 국내 건축법 등의 요구사항을 적용하여 UCN을 재구성한다. 결과적으로, 본 연구에서는 출구에서 가장 먼 점 (MRP) 기반의 동선 표현과 가상공간에서의 동선 분석이 추가적으로 제안되었다.

대부분의 기존 통합 리모컨은 동일한 제조회사의 특정 제품군만을 제어할 수 있다. 또한, 시그널 기반의 단방향 통신을 이용하므로 가전기기의 상태를 모니터링 할 수 없다. 본 연구에서는 Wireless Personal Area Network 상에서 가전기기의 상태를 관찰할 수 있는 동적 재구성이 가능한 양방향 통합 리모컨의 소프트웨어 프레임워크를 제안한다. 동적 재구성이 가능한 통합 리모컨은 제어 대상인 가전기기의 프로필에 따라 제어를 위한 GUI를 동적으로 생성함으로써 해당 가전기기를 제어할 수 있도록 재구성할 수 있다. 즉, 하나의 통합 리모컨을 통해 프로필을 가진 모든 가전기기를 제어하고 모니터링 할 수 있다.

Many students with disabilities and special needs are enrolled in higher education, which substantiated the need for research regarding faculty members' knowledge and willingness to implement supportive strategies in higher education in Saudi Arabia. This study explored Saudi university faculty members' knowledge and willingness to apply UDL (Universal Design for Learning) principles in their teaching practice. Surveys were used for data collection for this descriptive research. The findings indicated faculty members felt that they were knowledgeable regarding UDL and were willing to use UDL principles in teaching their students. Furthermore, there were no statistically significant differences between faculty members' knowledge levels regarding UDL based on their current position and years of experience. The findings indicated there was a significant relationship between gender and knowledge, with males having a significantly higher mean knowledge, although further analyses revealed it was a small effect. Finally, the results suggest more years of experience are related to greater willingness to use UDL principles, and this is particularly true for those in a lecturing position. These findings could be helpful, particularly for the Ministry of Education in Saudi Arabia to shed light on faculty members' UDL knowledge. Further research is needed to substantiate the findings.

A mobile agent system that searches for meaningful information from web XML documents is developed. For this, a domain information was conceptualized and a universal DTD generator is developed. A mobile agent with the universal DTD is dispatched to remote sites, extracts meaning information, and transmits the information back to a host. This way of information filtering is able to enhance the quality of information and reduce the network transmission overhead.

In this paper, we analyses of a traffic for authentication signaling in third generation mobile sensor network. In universal mobile telecommunication system, authentication functions are utilized to identify and authentication a mobile station and validate the service request network services. The authenticating parties are the authentication the serving general packet radio service support node access the authentication center to obtain the authentication with the mobile station. In this paper, we propose that the automatic cost-effective solution size of the authentication vector array.

Neuroprotection or prevention of neuronal loss is a complicated molecular process that is mediated by various cellular pathways. Use of different pharmacological agents as neuroprotectants has been reported especially in the last decades. These neuroprotective agents act through inhibition of inflammatory processes and apoptosis, attenuation of oxidative stress and reduction of free radicals. Control of this injurious molecular process is essential to the reduction of neuronal injuries and is associated with improved functional outcomes and recovery of the patients admitted to the intensive care unit. This study reviews neuroprotective agents and their mechanisms of action against central nervous system damages.

COVID-19 pandemic outbreak increased the use of Internet of Medical Things (IoMT), but the existing IoMT solutions are not free from attacks. This paper proposes a secure and resilient framework for IoMT, it computes the risk using Risk Impact Parameters (RIP) and Risk is also calculated based upon the Threat Events in the Internet of Medical Things (IoMT). UICC (Universal Integrated Circuit Card) and TPM (Trusted Platform Module) are used to ensure security in IoMT. PILAR Risk Management Tool is used to perform qualitative and quantitative risk analysis. It is designed to support the risk management process along long periods, providing incremental analysis as the safeguards improve.

Energy harvesting is an increasingly attractive source of power for cellular networks, and can be a promising solution for green networks. In this paper, we consider a cellular network with power beacons powering multiple mobile terminals with microwave power transfer in energy beamforming. In this network, the power beacons are powered by grid and renewable energy jointly. We adopt a dual-level control architecture, in which controllers collect information for a core controller, and the core controller has a real-time global view of the network. By implementing the water filling optimized power allocation strategy, the core controller optimizes the energy allocation among mobile terminals within the same cluster. In the proposed green energy cooperation paradigm, power beacons dynamically share their renewable energy by locally injecting/drawing renewable energy into/from other power beacons via the core controller. Then, we propose a new water filling optimized green energy cooperation management strategy, which jointly exploits water filling optimized power allocation strategy and green energy cooperation in cellular networks. Finally, we validate our works by simulations and show that the proposed water filling optimized green energy cooperation management strategy can achieve about 10% gains of MT's average rate and about 20% reduction of on-grid energy consumption.
