The purpose of the study was to explore the general characteristics of sports for all through the patterns of sports for all policy and analysis of causal relation of the determinants. To achieve this goal, 26 countries among OECD 30 members which provide useful data sources were selected. The data were analyzed by Qualitative Comparative Analysis(QCA) with cluster analysis. GDP, leisure time, social expenditure, Gini's coefficient, poverty rate and tax burden ratio were used as casual variables for Qualitative Comparative Analysis. The findings of this study were as follows. First, three patterns were examined and Korea was classified into the pattern which has low sports for all participation and sportsclub participation. Second, as a result of Qualitative Comparative Analysis for analyzing the determinants of sports for all patterns, the pattern in which includes Korea showed that GDP, leisure time, social expenditure, tax burden ratio had negative relationship and Gini's coefficient, poverty rate had positive relationship.

The purpose of this study is to analyze how the qualitative research is applied to mixed method research and thereby to gain an insight to suggest reasonable ways of employing qualitative method in order to accomplish intended goal of research, especially in the field of mathematics education. For that purpose, this study carefully selects and analyzes 5 article that used mixed method and were published by Education of Primary School Mathematics Journal in 2012. Unlike those a few previous studied on mixed method that focused on producing general trend by simply showing quantitative information on what the frequence of used research topic, content, methods combination, quantitative methods, and qualitative methods, this study provides detailed result of qualitative analysis on mixed studies. In sum, this study concludes with practical and in-depth suggestions on how to improve validity of mixed research and qualitative research in the field of mathematic of education.

We examine how combinations of key factors affecting healthcare user innovation vary by innovation stages from idea generation through R&D to commercialization and venturing using a fuzzy-set Qualitative Comparative Analysis (fsQCA) of thirty Korean cases in the healthcare field. Our empirical analysis shows that well-functioning innovation network and easy resource acquisition facilitate ideation of radical user innovation. However, technological capability and governmental support are crucial to make a shift to R&D as well as commercialization stages. Differently, incremental user innovation depends heavily on technological capability of users. Our analysis can provide policy makers as well as corporate innovation mangers with a strategic framework for boosting user innovation along three stages.

본 논문에서는 응용범위가 넓고 비교적 복잡도가 높은 화물운송 계획문제들을 대상으로 몇 가지 실험을 통해 대표적인 인공지능 계획방식인 부분순서 계획법과 그래프 계획법의 성능을 비교 분석하였다. 또 동시에 이러한 실험을 통해 DVO 및 LPVO와 같은 대표적인 제어전략들을 중심으로 이들이 그래프 계획법의 성능에 미치는 효과를 비교 분석하여 보았다. 본 연구의 실험을 통해서는 부분순서 계획법에 비해 그래프 계획법이 메모리 사용량이나 CPU 계산시간 면에서 월등히 우수한 성능을 보여주었으며 비교적 복잡도가 큰 계획문제에서도 좋은 결과를 보여주었다. 하지만 도출된 해 계획의 질적인 면에서는 부분순서 계획법이 대부분 최적의 해를 찾아낸 것에 반해 그래프 계획법은 사용된 제어전략과 최적화 방법에 따라 해 계획의 질이 크게 달라질 수 있음을 보였다. 한편 그래프 계획법에서는 부속목표 선택 전략인 DVO는 그 효과를 뚜렷이 보이지 못한 반면 동작 선택 전략인 LPVO는 도출된 해 계획의 질적인 면이나 계산속도 면에서 모두 뛰어난 효과를 보여주었다.

This paper introduces a new qualitative measurement indicator, Relatively Rank-normalized Impact Factor ($R^2nIF$) that can overcome drawbacks of the existing research performance measures. With the help of this innovative indicator, this study analyzes and compares the quality of research papers across countries and National Science Indicators (NSI) standard academic fields. The development of an improved bibliometric indicator for evaluating the quality of research papers and disentangling the "international" dimension of research performance will be of interest to academics and practitioners alike.

The purpose of this study was to examine what kind of changes adolescents experienced in the process of returning from the school dropout. For this purpose, 'Qualitative Meta-Analysis' was conducted for seven papers of this area, which was published in Korean journals as a method. 'Qualitative Meta-Analysis' is a method of presenting new interpretations by synthesizing qualitative studies on the same topic. In this study, the qualitative research on the process of returning from the school dropout was selected. The final articles selected for the analysis were seven articles published in domestic journals. The results obtained by comparing and analyzing the selected individual papers were as follows. For adolescents, a series of the process of returning from school dropout was 'self-growth through introspection and support.' In this process, there were five stages of change: abandonment, drifting, self-awareness, decisive action, and struggles. Relevant factors that led to this change were self-perception, the awareness of a reality, resources and support. Based on these results, the characteristics of each step were explained and discussed. Finally, the implications and limitations of the study were clarified and the follow-up study was proposed for more detailed examination.

The purpose of this study is to classify welfare regimes using the method of qualitative comparative analysis(QCA). By formalizing the logic of qualitative analysis, QCA makes it possible to bring the logic and empirical intensity of qualitative approaches to studies that normally call for the use of quantitative methods. In QCA each case is conceived holistically, as a configuration of conditions, not a collection of scores on variables. Major findings of this study are as follows. Firstly, major explanations for welfare state differences are partly supported. Indicators relevant to each explanation can appear to be important only if other causal conditions are considered. For example, in the interventionist welfare states, high GDP per capita must be combined with the weakness of the Right and ethnic homogeneity. Otherwise, it can't discern interventionist from liberalist welfare states. Secondly, the equation for the interventionist welfare states includes multiple causal conjunctures. Many studies of welfare state find the same results. The third main finding is that IDV(individualism index) which is proxy for the weakness of informal network matters. Combining with other variables, IDV seems to be important in explaining the emergence of Confucian welfare states.

이 연구는 한국 학계가 그간 많은 성장을 일구어 왔음에도 질적 수준에 대해서 지속적인 비판을 받고 있는 현 상황에 의문을 갖고 연구를 시작하였다. 최근 연구의 질적 수준 제고를 위해 연구개발 성과평가 제도가 전면적인 변화를 겪고 있음에도 정작 한국 학술연구의 질적 수준 문제가 어떠한 양상으로 나타나고 있는지 과학적인 증거를 제시하고자 하는 노력은 지금까지 매우 미흡했다. 이에 이 연구에서는 한국 연구의 양적 성장과 질적 성장 간의 괴리가 어떠한 양상으로 나타나는지 가시적인 일면을 제시하기 위하여 한국 연구자가 포함된 모든 SCI 논문을 수집하고 이를 대학, 출연연, 기업, 해외기관, 기타 소속 저자로 구분하여 양적 추세와 피인용횟수 추세를 비교하고자 하였다. 분석결과 해외기관 소속 저자와 국내기관 소속 저자 간에 유의미한 수준의 피인용횟수 격차가 나타나고 있으며, 이러한 격차는 시간의 흐름에 따라 해소되지 않고 있는 것을 확인하였다. 또한 분야별로 격차가 다르게 나타나 생화학 분자생물학이나 신경과학 신경학 등의 분야에서 피인용횟수의 격차가 보다 높게 나타나고 있었다. 이러한 결과는 최근 한국 공공연구 영역에서 전면적으로 일어나고 있는 질적 평가체제로의 전환 움직임에 대해서 그 세부적인 설계와 차등 요건의 적절성에 대해 다시 한 번 생각해볼 수 있는 계기를 제공한다.
