Quantitative and qualitative research explore various social phenomena using different methods. However, there has been a tendency to treat quantitative studies using complicated statistical techniques as more scientific and superior, whereas relatively few qualitative studies have been conducted in the medical and healthcare fields. This review aimed to provide a proper understanding of qualitative research. This review examined the characteristics of quantitative and qualitative research to help researchers select the appropriate qualitative research methodology. Qualitative research is applicable in following cases: (1) when an exploratory approach is required on a topic that is not well known, (2) when something cannot be explained fully with quantitative research, (3) when it is necessary to newly present a specific view on a research topic that is difficult to explain with existing views, (4) when it is inappropriate to present the rationale or theoretical proposition for designing hypotheses, as in quantitative research, and (5) when conducting research that requires detailed descriptive writing with literary expressions. Qualitative research is conducted in the following order: (1) selection of a research topic and question, (2) selection of a theoretical framework and methods, (3) literature analysis, (4) selection of the research participants and data collection methods, (5) data analysis and description of findings, and (6) research validation. This review can contribute to the more active use of qualitative research in healthcare, and the findings are expected to instill a proper understanding of qualitative research in researchers who review qualitative research reports and papers.

This study aims to construct the integrative performance evaluation model of informatization programs. In order to achieve the purpose of research, first of all, the three major theoretical paradigms (technical/functional, economic/financial, and interpretive/alternative paradigms) are comparatively analyzed concerning their philosophical and methodological perspectives. Also, a number of important studies and research model in the area of IS (Information Systems) evaluation are critically reviewed. And then actual problems and limitations on the process of implementing IS performance evaluation are sought through investigating domestic and foreign practices. Based upon theoretical and practical review of informatization evaluation and logical reasoning, the components of ideal performance evaluation scheme for informatization program are derived, and the integrative performance evaluation model which can comprehensively represent the relationship among the components is conceptually proposed. For researchers, this study provides the theoretical basis for reasonably deriving the performance variables of informatization programs and empirically validating the performance of managing informatization programs. And in real world, the results of this study are very likely to contribute to presenting the practical guideline for desirably implementing performance evaluation of informatization programs.

In this paper, we will examine the theoretical background and educational methodological basis of Novel engineering class cases published to date. For this purpose, we selected and investigated 30 Novel engineering-related academic papers and dissertations published from 2016 to 2023. As a result, the theoretical background is Seymour Papert's constructionism and Vygotsky's socio-cultural constructivism, and the educational methodological basis is creative problem-solving learning, problem-based learning, interdisciplinary convergence class, action learning, associating reading and writing education, possibility with integrated curriculum. We hope that this study will solidify the theoretical value of the Nobel Engineering convergence teaching model and serve as an alternative for teachers preparing for future education.

This study is based on education reforms related to strengthening information education in curriculums. This study develops and presents ' General Economics'Model Utilizing ICT(Information Communication & Technology) in Home Economics'which could be used as a concrete guidance and direction in teaching and learning Economics education in schools. To do so, this study reviews the necessity of adopting ICT in Home Economics instructional activities and it also reviews and analyzes previous studies of how ICT contribute to instructional activities. Such analysis was used as a theoretical basis for the Instructional Model. The Tool of ICT is a useful instructional strategy because it allows the learners'self-lead learning and Performance Assessment. Therefore the 'General Instructional Model Utilizing ICT'interprets the role of ICT tools to adequate class activities in each step of instruction which includes the conventional steps of introduction. development review and evaluation. It also develops and presents Lesson Plan that can be adopted in school education and thereby shows the possibility of practical application of the theory. This study has limits in that the Instructional Model and Lesson Plan are theoretical in nature. Therefore, in future studies it is desirable to critically review the Instructional Model an Lesson Plan and prove their applicability in real classes and the real learning effects.

Background & Objectives: Rising concerns about patient safety and looming health provider shortages were generating new recognition for an old idea. Interprofessional education means that two or more professions learn with, from and about other to improve collaboration and the quality of healthcare. The University of British Columbia established the College of Health Disciplines in 2001 to examine the merits of interprofessional health education. The objective of this study was to review UBC's interprofessional health education and to introduce the theoretical framework of interprofessional education for collaborative patient-centered practice. Methods: This study was conducted with the materials relevant to the interprofessional education. We reviewed the journals and Web site for this subject and we obtained interview data from administrators in the University of British Columbia, College of Health Disciplines. Results: We introduced interdisciplinary education for collaborative patient-centered practice model. It is assumed valuable model in preparing the interprofessional education as well as theoretical framework for implementation. We preseuted the example for interprofessional education of the College of Health Disciplines, University of British Columbia. Conclusion: We need to introduce the interprofessional education at the health care departments of University or College in Korea.

The purpose of this paper is to explore a new methodology for the historiography of Korean cos-tumes. In particular, I focus on the possibility for systematic, historical methods appropriate for the history of Korean costumes. First, I characterize the general historiography of costumes as involving two aspects-one as the social science and the other as historical science(Geschichteswissenschaft). My contention is that any historical study of costume should be established on the intersection of social and historical studies, and their entangling relations with many a neighboring field of sciences. It requires in other words, an interdisciplinary approach that combines various methodologies of social sciences as well as those of history. Second, I present an overall review of the historical methodology with a special emphasis on the“Quellenkunde”of orthodox historiography. Building on the review, third, I pay attention to recent innovations in historical methodologies, such as“New History”that draws on history, sociology and social history, and their applicability to the history of Korean costmes. In this regards. I adress among others, the following theoretical perspectives : 1) comparioson and comparative history, 2) the formatived and paternal approaches toward the history of costume, 3) particulartiy and universality of Korean costume. I conclued that the history of Korean costumes should broaden its theoretical horizon in order to accomodate a wider range of research agenda, including costumes of neighboring cultures, while remaining sensitive to new theories and methods of the neighboring social historical sciences. For this purpose, it is emphasized that an international collaboration among researchers of the region, as well as that across the different disciplinnary boundaries, is indispensable for successful studies that can embrace diverse fields and areas.

The prediction of diesel spray penetration has been the subject of several works and intensive investigations are still underway by many researchers. It is required to summarize the correlations developed before 1990 days and to introduce the correlations reported recently in the literature. The existing zero-dimensional models for the prediction of diesel fuel spray penetration can be classified as theoretical and empirical correlations. Of various correlations, the models considered in this paper were selected as based on the evaluation results of previous reviews and the recently published works in the literature. The existing theoretical correlations can be classified into seven categories and the existing empirical ones as two categories in this review. According to the review of existing models, the dominating factors for the prediction of spray tip penetration are the spray angle, discharge coefficient, pressure drop across nozzle, ambient density and orifice diameter and time after the start of injection. Especially, the definition for the measurement of spray angle is different with researchers. It is required to evaluate the existing spray tip penetration models for the very high injection pressure and other fuel sprays such as DME. It is also required to evaluate the correlations for the prediction of diesel spray penetration with the connection of liquid-phase penetration.
