네트워크 규모의 지속적인 확장으로 인해, 기존의 네트워크 트래픽 분류 방법으로 트래픽을 정확하게 식별하고 분류하기가 어려워졌다. 따라서, 최근에는 머신 러닝 기반 접근법이 네트워크 트래픽 분류에 가장 많이 사용되고 있으며, 앙상블 기법이 비교적 우수한 성능을 보인다. 본 논문에서는 앙상블 기법과 SDN 아키텍처를 활용한 네트워크 트래픽 분류 프레임워크를 제안하고, 제안된 프레임워크에서 실시간 네트워크 트래픽 분류가 잘 동작하는지 실험을 통해 확인한다.

Objectives:This study was conducted to compare emotional problems in children with neurosurgical diseases prior to surgery as well as levels of parenting stress experienced by mothers of children treated with surgery and those without surgery. The goals was to provide a basis on which comprehensive treatment interventions could be established. Methods:Subjects included 78 elementary school children who visited the Department of Pediatric Neurosurgery as well as their mothers. The Children’s Depression Inventory (CDI) and the Revised Children Manifest Anxiety Scale (RCMAS) were administered to children. The Parenting Stress Indexs (PSI) and Beck Depression Inventory (BDI) were administered to their mothers. Results:The children with neurosurgical diseases showed higher levels of depression prior to surgery. In their mothers, parenting stress was relatively higher and parenting competence was lower. In particular, for those children who underwent surgery, depression was significantly higher. Specifically, they exhibited more negative expectations, and negative self-image. In mothers of children who underwent surgery, depression was significantly higher. Conclusion:Our results suggest higher levels of emotional distress and parental stress in children who undergo neurosurgical operations and their mothers, respectively. Based on this, the necessity for surgical and comprehensive psychological intervention is suggested.
