In the context of Korean educational research, the number of qualitative research studies has gradually increased since 2000. It has become one of the most important research methods today. The field of math education is no exception to this trend, and qualitative approaches are now becoming one of the main research methods. This increase in qualitative research has contributed to the provision of detailed information about educational practice, but at the same time, the overall level of credibility in the results of qualitative research seems to be lower than that of quantitative research. This study started with the problem consciousness that the number of qualitative studies is increasing in the field of mathematical education, but there is a lack of discussion on the methodology of applying qualitative research methods. In this study, among the papers published in the journal related to mathematical education, papers using a qualitative approach are analyzed focusing on cross-case analysis. Based on the analysis results, the tendency to use qualitative approaches is diagnosed, ways of improving the validity and trustworthiness of qualitative research results in the field of mathematical education are examined, and implications and suggestions are presented.

The objective of public works planning is being converted from economic growth to sustainable development. So, the demand for considering social & ecological influences as well as economic components had been increased in evaluation of public works planning. In evaluation of public works, its components related with benefit and cost in feasibility analysis can be classified to qualitative and qualitative elements. Qualitative elements are evaluated by qualitative methods which can manage various items, be commonly applied nationwide, and consider elements that can be calculated numerically such as environments, willingness, etc. In this study, using the concept of 'Information measure', a method to design planning of rural works is proposed. 'Information benefit model' for rural works can evaluate present plan in the side of provider's and demander's 'benefit'. And, optimizing method of rural works by 'Information benefit' can simulate present state and optimize the site and route of rural works.

Qualitative research is a method widely used in marketing research. However, the method has seldom been used in fashion marketing research in Korea. The purpose of this study was to prove that using both qualitative and quantitative research methods in main stage is much useful than using qualitative research method only in exploratory stage. Qualitative data were gathered by conducting Focus Group Interview(FGI) with 48 college students. Quantitative data were gathered by surveying college students, and 487 questionnaires were used in the statistical analysis. The data were analyzed using content analysis, mean, standard deviation, and t-test. As a result, FGI, one of the tools used in qualitative research methods, was proved to be useful in revealing consumers´deep emotional needs as well as purchase motives. FGI also revealed information which quantitative research method tools such as survey could have missed. Therefore, it is best to use multiple methods-simultaneous use of quantitative and qualitative methods-to understand fast changing consumers´needs and purchase motives.

정성적 추론은 자연 세계에 대한 정성적, 직관적인 지식을 밝혀내어 코드화하는 목표를 갖고 연구되어 왔다. 정성적 추론은 전자, 기계 등의 도메인에서 성공적으로 사용되어 그 실효성을 입증할 수 있었으나, 대부분의 추론은 시뮬레이션에 집중되어 왔다. 본 연구에서는 주어진 상황에서 변화가 발생했을 때, 이 변화가 어떻게 영향을 미치며 파급되는지를 예측할 수 있는 정성적 비교분석 기법을 소개하고자 한다. 본 연구에서는 파라미터의 상대적인 변화의 파급만을 예측한 기존의 연구에 상대적 변화의 증가율 변화에 대한 추론을 추가하여 확장하였다. 상대적인 주어진 상황에 대한 인과모델이 정성적 분야 모델로부터 형성되고, 여기에 비교분석 추론 기법을 적용하여 변화의 연쇄적인 인과 관계를 추적하게 된다. 이러한 기법은 변화의 예측 뿐 아니라, 이런 변화를 이끌어낸 인과 관계를 설명하는 기능을 제공하게 되어, 디자인, 진단, 지능형 교육 시스템, 환경 영향평가 등에 이용되리라 기대된다.

This study aims at introducing 'ethnography' which is one of the most representative qualitative research methods into Library and Information Science research in Korea.. Ethnography, derived from anthropology, helps researchers to understand the whole and deep aspect of the research object. That is because the researcher puts himself into the life-world of the research object and observes it for a long time. Ethnography can be used as an alternative method to quantitative research methods. Until now, Library and Information Science research in Korea has used quantitative research methods in almost every case. From the 1980s so-called 'scientific methods' using hypotheses testing, have provided the major premise for research methodology in Library and Information Science of Korea. And the researchers have seen their research object(Korean Libraries) not in the native perspective but largely in the western(especially American) perspective. There is a need in Korea for more culturally relative research. So the desirability of introducing ethnography and other qualitative research methods into Library and Information Science research in Korea can be summarized as follows : I. Ethnography and other qualitative methods are needed for the researchers to overcome the limitation of quantitative methods which have formed the main methodological paradigm in Library and Information Science research in Korea. While those quantitative scientific methods can be a n.0, pplied to the social sciences, they are not adequate for the social sciences. It is because the research objects of the social sciences are human and social phenomena. II. It is needed that Library and Information Science research in Korea pay more attention to the speciality of Korean libraries. To do researches based on the viewpoint of cultural-relativism, researchers should consider the cultural context of Korean libraries. During the past years researchers in other social science fields in Korea, especially sociology and pedagogy, have gradually a n.0, pplied the methods of ethnography to their fields. These social scientists have attempted to escape from ethnocentrism, a problem which has greatly influenced past and present research methods. To get a holistic and in-depth understanding of Korean libraries on the present stage, and to solve their problems radically, it seems imperative that Library and Information Science research in Korea pay more attention to qualitative research methods such as ethnography.
