Recently process industries from oil and gas procedures and mining companies to manufactures of chemicals, foods, and beverages has been exploring the USN (Ubiquitous Sensor Networks) technology to improve safety of production processes. However, to apply the USN technology in the large-scale plant industry, reliability and security issues are not fully addressed yet, and the absence of the industrial sensor networking standard causes a compatibility problem with legacy equipment and systems. Although this situation, process industry such as energy plants are looking for the secure wireless plant solution to provide detailed, accurate safety monitoring from previously hard-reach, unaccordable area. In this paper, SPSF (Smart Plant Safety Framework based on Reliable-Secure USN) is suggested to fulfill the requirements of high-risk industrial environments for highly secure, reliable data collection and plant monitoring that is resistant to interference. The SPSF consists of three main layers: 1) Smart Safety Sensing Layer, 2) Smart Safety Network Layers, 3) Plant Network System Layer.

도시가스 배관에서 노출배관 위험요소에 대한 모니터링이 필요하나 현재는 인위적으로 사람에 의해 확인하거나 유선 기반의 감시 시스템이 존재한다. 이에 대한 제반 비용을 감소시키면서 무선 기반의 감시 인프라를 구축하기 위해 본 연구에서는 노출배관의 위험요소 중에서 가장 중용한 응력과 진동을 측정하고 CDMA 방식을 이용하여 모니터링 시스템에 전달해주는 시스템을 구축하며 실제 환경에서 시험환경(Test-bed)을 조성하여 대상 시설 및 설치 환경에 따라 최적화된 기기 및 인프라를 구축하는 것을 본 연구에서 기밸반된 도시가스 안전 유비쿼터스 인프라에 통합시키는 것을 목적으로 한다.

Staphylococcus aureus is a ubiquitous pathogen associated with both human and animal diseases. In this study, we present the complete genome sequence of SA73-2, which was isolated from lettuce at an agricultural farm in South Korea. The assembled genome consists of a 2,750,304-bp circular chromosome and a 24,654-bp plasmid. This strain belongs to sequence type 188 (ST188), with spa type 189, and carries the β-lactamase gene (blaZ) on the plasmid.

In this paper, the u-Service system that is based on location-aware technology is designed for a silver town. It provides services such as emergency call, intelligent elevator operation, and hands-free door access based on the location of the residents with personal device as called smart tag. It can also be applied to other service areas such as the location-aware u-Service for Hospital, high-rising complex building, APT, etc.

RFID has been used as an identification tool substituting bar-code and its application areas are increasing due to its suitability in ubiquitous environment. This paper reviews RFID applications in some areas in which a serious amount of applications were reported such as material handling, physical distribution, and supply chain management of perishable products. The authors try to suggest research issues along with the limitations of RFID.
