김근혜(Geun Hye Kim),장은정(Eun Jung Chang),최황규(Hwang Kyu Choi) 한국정보과학회 1998 한국정보과학회 학술발표논문집 Vol.25 No.2Ⅲ

본 논문은 RAID5가 갖는 작은 쓰기 문제를 극복하기 위하여 지금까지의 연구 중에서 가장 우수한 성능을 나타내는 패리티 로깅 기법의 단점을 개선한 새로운 패리티 로깅 기법을 제안한다. 제안된 기법은 패리티 로깅기법에서 가장 큰 오버헤드인 패리티 로그의 크기를 줄이기 위하여 로그 데이터를 압축하는 방법을 사용한다. 로그 데이터의 압축은 로그 데이터의 저장에 필요한 비휘발성 버퍼의 크기와 로그 데이터 접근시간을 감소시켜 전체적인 성능을 향상시킬 수 있다. 시뮬레이션을 통한 성능분석 결과에서 제안된 기법은 기존의 패리티 로깅 기법에 비하여 디스크 접근시간에서 우수한 성능을 나타냄을 보인다.

There was a significant difference of mothers` parenting stress according to their husbands` educational backgrounds. Second, there were significant differences of mothers` parenting stress according to fathers` levels of parenting involvement. Third, mothers level of education and home total monthly income in the first and second step of the hierarchical multiple regression respectively. But mothers` total parenting stress was significantly influenced by one factor(R2=.22.8): fathers` ``guiding of the life``(β=-.280, P<.05) which was a sub-scale of father`s parenting involvement in the third step of the hierarchical multiple regression analysis. In conclusion, it is necessary to encourage fathers` parenting involvement in and out of the home to reduce mothers` parenting stress.
