The purpose of this research is to study the meanings and characteristics of qualitative research method in LIS. As the philosophy and epistemology of qualitative research are widely different from those of quantitative research, the meaning of validity and reliability must be interpreted in its ow9 structure and dimension. Essentially qualitative researchers seek to understand and interpret the world of others from their own viewpoints which basically tend to be subjective. Accordingly, qualitative researchers‘ understandings and interpretations are met with readers' subjectivity. By carefully analyzing the nature of qualitative research in LIS, I tried to point out some problems in terms of validity and reliability and practical strategies. Six problems issued in the qualitative research method are presented.

이 연구는 Hewitt과 Flett(1991c), 이기종(2006)이 제안한 완벽주의 척도 연구모형의 타당도를 확인적 요인분석을 통해 검증하고, Hewitt과 Flett(1991c)이 개발한 완벽주의 척도의 문항이 몇 개의 요인으로 구성되는지 알아보기 위해 탐색적 요인분석을 실시하였다. 확인적 요인분석 결과 Hewitt과 Flett(1991c), 이기종(2006)이 각각 제안한 연구모형과 수집된 자료가 잘 합치하지 않았다. 따라서 자료에 모형이 잘 맞도록 모형을 수정해야 하고, 의미 없는 자유모수가 모형에서 나타나지 않도록 모형을 다시 설정해야 함을 알 수 있다. 또한 Hewitt과 Flett(1991c)이 개발한 완벽주의 척도의 탐색적 요인분석을 통해 완벽주의 척도의 각 문항들이 완벽주의를 측정하는데 있어서 단일요인으로 제 기능을 하기 보다는 여러 문항에 걸쳐 공통요인이 존재함을 알 수 있다. 따라서 확인적 요인분석과 탐색적 요인분석을 통해 Hewitt과 Flett(1991c)이 개발한 완벽주의 척도가 측정하는 요인은 3개 요인으로 설명될 수 없다고 판단된다. 그러므로 Hewitt과 Flett(1991c)이 개발한 완벽주의 척도의 측정 문항이 수정되어야 하고, 나가서 우리의 사회 문화적 실정을 고려한 완벽주의 척도의 개발이 시급함을 알 수 있다.

To study reliability and validity of PWI, this newly developed self-administered questionnaire which measures stress, was given to medical students. All respondent(133) were followed 4 weeks later and 92 were retested. Cronbach's $\alpha$ coefficient of data was 0.93. Test-retest reliability measured by Pearson's correlation coefficient was 0.72(P<0.01). Exploratory factor analysis(EFA) performed by principal axis factor method without iteration and by varimax rotation explored 13 principal components(eigenvalues > 1). After exploring 4 factor structure according to previous study results, factor 1 showed good agreement but other factors did not. Confirmatory factor analysis(CFA) showed poor fit of 4 factor model to data. In the further study, it may be considered to model that has unidimensional factor structure.

The purpose of this study was to develop the classification of home-based long-term care activities and to test its validity. In this study, the taxonomy of long-term care activities was structured according to the service domain and process. Two expert groups participated in making a draft of the taxonomy that was composed of 7 service domains, 22 care needs, 22 service objectives, and 114 activities. Reliability and validity of the taxonomy was tested in a sample of 152 elderly subjects who used the home-based long-term care services. Based on the factor analysis of 114 activities, 21 factors were extracted from 114 activities. Internal consistency of the factors was high. Content validity was confirmed by the CVI. Long-term care insurance grade was used to assess the criterion validity. Among 21 care needs, 12 cares needs were significantly different from their grade. The classification of home-based long-term care activities demonstrated reliability and validity. In conclusion, the use of this classification is recommended while communicating with the elderly subjects, service providers, and the 3rd party payers.

This study aimed to investigate pre-service science teachers' perceptions of significance and usefulness of evolution and genetics. To this end, 82 pre-service biology teachers and 159 non-biology science teachers answered the items to measure the perceptions of significance and usefulness of evolution and genetics. The validity and reliability were examined using Cronbach alpha, two-dimensional rating scale model Rasch analysis, and factor analysis. The finding illustrated that the test items met the benchmark to be valid and reliable test items. Second, pre-service teachers' perception of significance and usefulness of evolution was independent to that of genetics. The level of pre-service teachers' perception of significance and usefulness of evolution was lower than the level of genetics. Lastly, the levels of pre-service teachers' perceptions of significance and usefulness of evolution and genetics were not significantly different across academic years and majors (biology and non-biology). The findings of this study stressed the importance of teaching significance and usefulness of evolution and genetics in pre-service science teacher education program.
