Qualitative research methodology has been applied with increasing frequency in various fields, including in healthcare research, where quantitative research methodology has traditionally dominated, with an empirically driven approach involving statistical analysis. Drawing upon artifacts and verbal data collected from in-depth interviews or participatory observations, qualitative research examines the comprehensive experiences of research participants who have experienced salient yet unappreciated phenomena. In this study, we review 6 representative qualitative research methodologies in terms of their characteristics and analysis methods: consensual qualitative research, phenomenological research, qualitative case study, grounded theory, photovoice, and content analysis. We mainly focus on specific aspects of data analysis and the description of results, while also providing a brief overview of each methodology's philosophical background. Furthermore, since quantitative researchers have criticized qualitative research methodology for its perceived lack of validity, we examine various validation methods of qualitative research. This review article intends to assist researchers in employing an ideal qualitative research methodology and in reviewing and evaluating qualitative research with proper standards and criteria.

In order to examine the ways to improve the efficiency of R&D investment, this paper presents analysis on both quantitative and qualitative efficiency of R&D projects. As Korea's R&D investment has significantly increased in recent years, the efficiency of R&D investment has attracted attention. In this paper, a Data Envelopment Analysis(DEA) method is used to construct models for quantitative efficiency and qualitative efficiency analysis. Based on a cases of agricultural R&D projects of Korea, the efficiency of national R&D projects were analyzed and their quantitative and qualitative efficiencies are compared. As a result, statistically significant difference between quantitative and qualitative efficiency was found. Also, characteristics of Decision Making Units(DMUs) which can influence both quantitative and qualitative efficiency were identified. In particular, the stage of a R&D project has significant impact on R&D efficiency. This study suggests that in order to enhance R&D efficiency both quantitative and qualitative nature of outputs should be considered when measuring R&D efficiency.

Purpose: The purpose of this study was to analyze reports of qualitative research published in Journal of Korean Academy of Fundamentals of Nursing (JKAFN). Methods: Twenty four qualitative research studies using in-depth interviews and focus group interviews published in JKAFN from 1994 to 2014 were selected for analysis. Chosen reports were analyzed by consolidated criteria for reporting qualitative research (COREQ), which is a reporting guideline for qualitative research. COREQ consists of 32 items and 3 domains. Results: In the 1st domain, the relationship of researchers and research participants, bias and understanding of the researchers on the study phenomenon were analyzed less than other items. In the 2nd domain, methodological research was carried out across various qualitative studies, but the description of the research environment and research questions for the interview guidelines was insufficient. In the 3rd domain, research results and data were consistent, but data showing opposing content and explanations of negative practices were not done at all. Conclusion: These results indicate a need for the development of evaluation tools for qualitative research and items should be added to improve the reliability and validity, research should be related to the ethics in the framework of the COREQ.

Objectives: To analyze the reports of qualitative research about natural disasters in Korea. Methods: Nine published qualitative research studies were selected for the analysis. The selected reports were analyzed by Consolidated Criteria for Reporting Qualitative Research (COREQ), a reporting guideline for qualitative research. In addition, each subject of the study was qualitatively synthesized. Results: In the quality assessment using COREQ, detailed information about the researchers were insufficient. The results of the studies were integrated into six themes: "Disaster experience", "Disaster damage", "Dealing with disasters", "Disaster compensation issues", "Arbitration Resources", and "Post-disaster change". Conclusions: In further qualitative research on natural disasters, it is necessary to report the research according to the COREQ checklist. Based on the results of this study, continuous attention and research are needed to explore the areas of Korean medicine care in the event of a disaster.

Purpose: Exploring the variables that predict teachers' intent when referring students to mental health professionals is important. The Theory of Planned Behavio (TPB) is a theory of predicting people's intentions of performing a particular behavior; the intent to perform a certain behavior is determined by three factors. (1) attitudes toward the behavior, (2) subjective norms, and (3) perceived control. This study aimed to develop a TPB measurement to investigate what variables predict the intentions of teacher's referral behaviors. Methods: A qualitative study following standardized manuals and guidelines for developing a TPB measurement was used. As a qualitative research method, the Consensual Qualitative Research-Modified (CQR-M) was used. According to the findings from the qualitative study, the quantitative measurement to assess teachers' referral intention, attitude, subjective norm, and behavioral control was developed. Results: The reliability and validity of the newly developed measurement were tested and verified. Conclusion: The newly developed measurement would contribute to a future empirical study that will examine predictors of teachers' referral intention.

Objectives This research was aimed to analyze and assess the articles of qualitative research of Pediatrics by following Consolidated Criteria for Reporting Qualitative Research (COREQ). Methods Two researchers analyzed and assessed the reports' quality and appropriateness based on COREQ guideline. The articles that failed to achieve consensus from the two researchers, the third researcher made a final decision. Results A total of fifty-six reports which used caregivers as participants, were selected and adopted qualitative research methods were chosen. In most qualitative studies, COREQ was not implemented. Some parts of the studies were poorly described and elaborated when reviewing them based on the COREQ guidelines. In the 'Research team and reflexivity', there was lack of description about the researcher. In the 'Study design', there were no detailed descriptions on the approaches they took in recruiting their study participants. There was not enough detail reflexivity participants who refused, and where the recruitment took place. There were also no records of whether there was a pilot test or a data saturation. In 'Analysis and findings' section, there were few articles mentioning Participant checking, and the main opinion of the participants were well analyzed in all the papers, but excluding opinions of few participants. Conclusions There are still many qualitative studies that have caregivers as participants, in the field of pediatrics. However, methodological skills are insufficient. The use of the COREQ guidelines should be further implemented for more robust and methodological improvement.
