  • 본 논문에서는 다중 컨트롤러가 존재하는 분산 SDN 환경에서 과도한 제어 메시지로 인한 과부하된 컨트롤러의 부하를 줄이기 위하여 이주할 스위치를 K-means 군집화와 Harmony Search(HS)를 기반으로 선정 하는 기법을 제안하였다. 기존에 HS를 이용하여 이주할 스위치를 선택하는 기법이 제시되었으나, 시간 소모에 비하여 정확도가 부족한 단점이 있다. 또한 Harmony Memory(HM) 구축을 위해 메모리 소모 또한 크다. 이를 해결하기 위하여 본 논문에서는 유클리드 거리를 기반으로 하는 K-means 군집화를 이용하여 이주할 스위치를 골라내어 HM의 크기를 줄이고 이주 효율을 향상 시킨다.

A Method of Using Digital Map to Improve Multicultural Education Efficiency: A Design of 'e-Atlas of Society and Culture' for Marriage Immigrant Women to Overcome Contextual Limitations (다문화교육 효율성 제고를 위한 전자지도의 활용방안 -결혼이주여성의 맥락적 한계 극복을 위한 'e-사회문화지도'설계-)

  • In this paper, we study on an 'e-Atlas of Society & Culture(e-ASC)', to develop and implement educational courseware for marriage immigrant women, to adapt Korean society. The 'e-ASC' can help cultural adaptation, such as the understanding of Korean people's common values and behaviors and can likewise provide opportunities to contribute to Korean society, for marriage immigrant women living in Korea. E-cultural map is a useful tool for providing educational experiences and sharing a sociocultural homogeneity, using three dimensional space, for both immigrants and residents. The 'e-Atlas of Society & Culture', suggested in this paper, using the notion of an E-cultural map, has a strong point. That is to say, the immigrants have contextual limitations about Korea and Korean culture, caused by some particular events in their motherland. This atlas provides an opportunity to overcome this contextual limitations and to help understand and adapt to Korean society for these immigrants. This 'e-Atlas of Society & Culture' can be an efficient educational tool for immigrants and can help marriage immigrant women understand and adapt Korean social and cultural phenomena. They might have contextual limitations about these phenomena in their motherland.
