  • 2008년 12월 1일 '눈에 보이지 않는 일'을 사고파는 시장이 열린다. 기존 구인 구직의 개념이 아닌, 웹상에서 기업은 '일'단위로 인력을 모집하고, 구직자는 회사가 아닌 '일'을 선택하는 전자일감시장 이워크랜드(www.eworkland.co.kr)가 이달의 첫날 정식 오픈하였다. 유비쿼터스 환경을 바탕으로 시공간의 제약을 받지 않는 새로운 전자일감시장을 연 주인공은 시너지 프레임이라는 개발 프레임워크로 널리 알려진 강소벤처 아토정보기술(www.attoit.co.kr). 야심찬 서비스를 준비하고 누구보다 떨리는 가슴으로 올해의 마지막 달을 맞이하는 아토정보기술의 강관식 대표를 만나본다.

  • As the Korea Railroad (KR) was privatized at the beginning of 2005, the Korean Railway Standards (KRS), which was managed previously by KR, have been managed by the Korean Ministry of Construction and Transportation. According to Railway Safety Law and ordinances, which are for the guarantee of safety in railway applications, the management of KRS including enactment and revision of technical standards for railway vehicle and components, was committed to Korea Railroad Research Institute. In this investigation, the detailed management plan and contents are introduced for the effective management of KRS.

  • We define a class of semi-symmetric metric connection on a Riemannian manifold for which the conformal, the projective, the concircular, the quasi conformal and the m-projective curvature tensors are invariant. We also study the properties of semisymmetric, Ricci semisymmetric and Eisenhart problems for solving second order parallel symmetric and skew-symmetric tensors on the Riemannian manifolds equipped with a semi-symmetric metric P-connection.

  • Neuronal hyperexcitability followed by high level of intracellular calcium and oxidative stress play critical roles in neuronal cell death in stroke and neurotrauma. Hence, KR-31378, a novel benzopyran derivative was designed as a new therapeutic strategy for neuroprotection possessing both anti-oxidant and potassium channel modulating activities. In the present study, we tested for its neuroprotective efficacy against oxidative stress-induced cell death in primary cortical cultures and further investigated its neuroprotective mechanism.
