DNA microarray 기술은 동시적으로 수천 개의 유전자의 발현상황을 탐색할 수 있다. 이 기술을 통해 얻어진 자료는 분석하기에 앞서 전처리 과정으로 배경보정 (background correction), 표준화 (normalization) 그리고 요약 (summarization)이 필요하다. 표준화란 microarray 실험에서 기술상의 문제로 첨가되는 일정한 잡음을 인식, 제거하기 위해 필요한 기법으로 그 동안 여러 방법들이 제시되어 왔다. 또한 마이크로어레이 자료의 분석을 위한 요약 방법으로도 많은 방법들이 연구되었다. 본 글에서는 표준화 방법들과 요약 방법들의 특성을 분석, 비교하고자 한다.

Objectives: The purpose of the study was to investigate the relationships among snack habits, oral health practice, and oral health status in preschool children. Methods: The subjects were 209 preschool children and their mothers in Jeonbuk from March 24 to May 30, 2014. The study instruments comprised snack habits, oral health practice, and oral health status. Data were analyzed for independent t-test, one way ANOVA and hierarchical multiple regression using SPSS Win 21.0 version. Results: Higher dft index was shown in the older age (p=0.033), lower mother`s education (p<0.001), lower mother`s daily toothbrushing (p<0.001), check-up after tooth-brushing (p<0.001), tooth-brushing practice before sleeping (p<0.001), tooth-brushing practice after snack (p<0.001), regular dental check-up (p<0.001), fluoride and sealant for prevention caries (p<0.001), limitation of sugar snack intake (p<0.007), periodic replacement toothbrush (p=0.022). The cause of higher dft index included soda (p<0.001), yogurt (p<0.001), snack (p=0.002), bread and cake (p=0.002) and caramel and candy (p<0.001). Fruit (p<0.001), vegetable (p<0.001) and milk (p=0.004) decreased dft index. Factors affecting oral health status were tooth-brushing practice before sleeping, tooth-brushing practice after snack, regular dental check-up, fluoride and sealant for prevention caries, and intake of soda, yogurt, caramel, candy, and fruit. The explanation power of the final model was 67.6%. Conclusions: It is necessary to develop the oral health education program for the preschool children and mothers to enhance the best oral health condition.

Objectives: This study was examine a relationship those variables with healt -related quality(HRQOL) of life in the elderly and provide basic information on HRQOL and evidence for establishing effective health policies for old ages ultimately. Methods: This research was conducted through individual interviews using a structured questionnaire and oral status examinations of 600 residents The data have been analyzed using ²-test through PASW Statistics 18.0.0(SPSS Korea Datasolution Inc.) and Structural Equation Modeling through LISREL ver8.8. Results: According to the Structural Equation Modeling, independent variables which influence the health-related quality of life are as follows: sex the highest, followed by existence of chronic diseases, perceived health, age, perceived oral health the lowest. Parameters are as follows: oral health-related quality of life the highest, followed by subjective oral symptoms, and oral health status the lowest. Conclusions: In order to improve the quality of life of olds, it is not only necessary to improve perceived health through reduce of chronic diseases, but is also required to regular tooth check-up to reduce subjective oral symptoms for increase oral health-related quality of life.
