  • The evolving internet-based services demand high-speed data transmission in conjunction with scalability. The next generation optical network has to exploit artificial intelligence and cognitive techniques to cope with the emerging requirements. This work proposes a novel way to solve the dynamic provisioning problem in optical network. The provisioning in optical network involves the computation of routes and the reservation of wavelenghs (Routing and Wavelength assignment-RWA). This is an extensively studied multi-objective optimization problem and its complexity is known to be NP-Complete. As the exact algorithms incurs more running time, the heuristic based approaches have been widely preferred to solve this problem. Recently the software-defined networking has impacted the way the optical pipes are configured and monitored. This work proposes the dynamic selection of path computation algorithms in response to the changing service requirements and network scenarios. A software-defined controller mechanism with a novel packet matching feature was proposed to dynamically match the traffic demands with the appropriate algorithm. A software-defined controller with Path Computation Element-PCE was created in the ONOS tool. A simulation study was performed with the case study of dynamic path establishment in ONOS-Open Network Operating System based software defined controller environment. A java based NOX controller was configured with a parent path computation element. The child path computation elements were configured with different path computation algorithms under the control of the parent path computation element. The use case of dynamic bulk path creation was considered. The algorithm selection method is compared with the existing single algorithm based method and the results are analyzed.

  • 세계지리경시대회는 비록 짧은 역사에도 불구하고 국제지리학연합(IGU)이 인정하는 최고의 국제적 공식학력경시대회이다. 본 연구에서는 우선 세계지리경시대회의 성격과 진행과정 그리고 대회규정을 정리하고, 경시대회를 통하여 한국 고등학생들이 거둔 학업성취도에 대한 국제적인 수준을 비교.분석하였다. 이를 위해 경시대회의 핵심인 시험성적을 국가별로 분석하였고, 참가한 한국 고등학생들의 성적을 시험 항목에 따라 재분류하여 평가함으로써 우리나라 고등학교 지리교육 학업성취도를 유추하였다. 또한 경시대회 출제문제를 주제별.나이도별로 나눠 평가하고 헤이그 대회와 비교하였으며, 서울 경시대회에서 팀 단위 우승국인 폴란드의 지리교육과 경시대회의 준비과정을 살펴보았다. 서울 대회는 13개 국에서 선발된 39명의 고교생을 비롯하여 총 76명이 참여하였다. 경시대회의 국가별 성적은 폴란드. 네덜란드, 한국, 라트비아, 루마니아, 벨기에, 러시아 등의 순위이며, S 자 형태의 성적분포패턴을 보여 학업성취도의 측면에서 상위권-중위권-하위권의 패턴을 어느 정도 확인하였다. 특히 지난 대회를 함께 고려할 때 폴란드가 계속 강세를 보이고 있다는 점이 특징이며, 처음 경시대회에 참가한 우리 나라는 전체적으로 2위라는 우수한 성적을 거두었지만 우리 국토를 대상으로 하는 답사시험에서 중위권에 머무른 결과는 어느 정도 현장교육의 문제점이 드러나고 있음을 의미하고 있다.

  • Recently the demand for civil security and security guards shows rapid growth. However the supply and training system have some limitations. Educational and training systems for civil body and security guards are in the basic level and private organizations trained the professional work force. So this paper is showing what a social dominant factor and a divice of development of the private security. Capitalism is based on a material desire of the human being. the social control of capital value and the management of capital ability reflects the actual condition of the capitalism well. The unconstrained growing and the expansion of capitalism, it finally lost social meaning and an importance of human being element and the safety of the civilian life, began to threat the security of citizen by forming over the material center structure of society. Improving human life quality and material richness on their life leads positive factor of capitalism whereas is causing several crimes through the society which is being threatened around a human being life for a negative factor of the capitalism. Therefore capitalistic social system has offered both a positive factor 'growing' and 'richness' and that of a negative 'structural poverty' and 'lack of security' and they have been remaining the assignment of capitalism 'poverty' and 'security' by settlement in the society for a extremely phenomenon of both sides. In Korea because their recognition of the study approach and the social safety for social security control function is still staying first step and our daily life is annoying from various threat of the society. many studies and the realistic necessity of experience related with social security is being studied. In addition. The development possibility of the civil guard and defense at the civil field which will be keep the social security has a wide position but its study approach and realistic comprehension is still in insufficient condition.
