Nowadays, wireless sensor networks (WSNs) have been widely adopted in structural health monitoring (SHM) systems for social overhead capital (SOC) public infrastructures. Structural health information, environmental disturbances and sudden changes of weather conditions, damage detections, and external load quantizing are among the capabilities required of SHM systems. These information requires an efficient transmission with which an efficient mobility management support for wireless networks can provide. This paper deals with the analysis of mobility management schemes in order to address the real-time requirement of data traffic delivery for critical SHM information. The host-based and network-based mobility management protocols have been identified and the advantages of network mobility (NEMO) enabled Proxy Mobile Internet Protocol version 6 (PMIPv6) have been leveraged in order to address the SHM information transmission needs. The scheme allows an efficient information transmission as it improves the handover performance due to shortened handover latency as well as reduced signaling overhead.

As urbanization increases in UAE, the demand for housing and infrastructures also grows. The challenge is to continue to build but in a different way considering more energy-efficient sustainable buildings. Producing a sustainable design is highly dependent upon effective participation among the diverse parties involved. In the construction industry in the UAE, these parties are fragmented due to the multistage nature of construction projects and multidisciplinary participants, particularly during the design stage. The decisions made during this stage have an extensive impact on subsequent stages of a project's life cycle. Having a sustainability expert during the design stage is important and the awareness of sustainability requirements by all design participants is of equal importance. In this research, recent advances in information technology are used to develop an information model that will improve the sustainability of building during the design stage. An information framework for storing design information and sustainability performance criteria is developed, allowing design participants to collaborate in an integrated environment. This research is expected to help designers produce sustainable designs for building projects.

In reflection of road expansion and increasing use rates, interest has blossomed in predicting driving environment. In addition, a gigantic scale of big data is applied to almost every area around the world. Recently, technology development is being promoted in the area of road traffic particularly for traffic information service and analysis system in utilization of big data. This study examines actual cases of road management systems and road information analysis technologies, home and abroad. Based on the result, the limitations of existing technologies and road management systems are analyzed. In this study, a development direction and expected effort of the prediction of road information are presented. This study also examines regression analysis about relationship between guide name and traffic volume. According to the development of driving environment prediction platform, it will be possible to serve more reliable road information and also it will make safe and smart road infrastructures.

Nowadays, nations cyber security capabilities play an important role in a nation's defense. Security-critical infrastructures such as national defenses, public services, and financial services are now exposed to Advanced Persistent Threats (APT) and their resistance to such attacks effects the nations stability. Currently Cyber Threat Intelligence (CTI) is widely used by organizations to mitigate and deter APT for its ability to proactively protect their assets by using evidence-based knowledge. The evidence-based knowledge information can be exchanged among organizations and used by the receiving party to strengthen their cyber security management. This paper will discuss on the business process reengineering of the CTI information exchange management for a nationwide scaled control and governance by the government to better protect their national information security assets.

정보통신의 기술 발달로 인하여 국가안보와 직접적으로 관련된 국가사회의 주요인프라인 에너지 기반구조, 물류 기반구조, 금융 기반구조, 생활필수 기반구조가 상호 연결되면서 상호의존성이 크게 증가하고 있다. 국가기반구조가 정보통신 기반구조와 밀접하게 연결되면 다양한 정보서비스를 제공하는 긍정적인 측면과 더불어 새로운 위험요인을 내포하게 된다. 그러나 지금까지의 현대정보사회의 기술위험에 관한 논의는 원자력 사고, 화재, 교통재해, 가스안전사고 등 공중에게 직접적인 피해를 입히는 1차적 위험요소에 초점을 두고 있었던 반면, 그것 자체가 직접적인 위험요소는 아니지만 일단 사고가 발생하면 정보통신 기술의 발달로 인해 이루어진 국가기반구조 전반에 대한 운행(operation)을 저해하고 제반 위험관리기능을 마비시킴으로써 보다 광범위한 위험을 발생시킬 수 있는 제2차적인 위험요소에 대한 연구는 별로 없었다고 할 수 있다. 사회의 모든 부문에서 자동화와 정보화가 진행될수록 전기에 대한 의존이 커지는 이른 바 ‘전력화현상(electrification)'이 심화되고 있음을 감안할 때, 정보사회의 안보(安保)(security) 저해요소로서의 정전의 중요성이 갈수록 높아진다고 하겠다. 따라서 대규모 정전사태의 문제는 국가위기관리 차원에서 효과적으로 다루어야 하며 정보사회로의 진전이 급속도로 이루어질수록 대규모 정전사태에 대비한 관리체계가 매우 중요하다고 하겠다. 여기에서는 지금까지 발생한 대규모 정전사태의 사례를 분석하고 발생 원인을 심층적으로 살펴본 다음 한국의 정전관리체계를 국가위기관리 단계인 예방(완화 및 대비), 대응, 복구(보상) 단계에 대대 각각 조사해보았다. 결론에서는 보다 나은 효율적인 정전관리체계 수립을 위한 정책적 제안으로 전력의 안전공급체제 견지, 비상전원 설치에 대한 정책적 지원, 정전피해보상제도 개선 등을 제시하였다.

Mobile Ad Hoc Network (MANET) is a network architecture, which has no backbone network and is deployed temporarily and rapidly in emergency or war without fixed mobile infrastructures. All communications between network entities are carried in ad-hoc networks over the wireless medium. Due to the radio communications being extremely vulnerable to propagation impairments, connectivity between network nodes is not guaranteed. Therefore, previously developed routing algorithms in wired networks cannot be used. And many new algorithms have been undergone. This study proposes the secondary leader approach to the cluster based routing protocol(CBRP). In case, the primary leader becomes abnormal status so that the primary leader cannot participate the communications between network entities, the secondary leader immediately replaces the primary header without selecting process of the new primary leader. The performances of proposed algorithm ACBRP(Advanced Cluster. Based Routing Protocol;CBRP using secondary leader) are compared with CBRP and results are presented in order to show the effectiveness of the algorithm.
