김경화 한국미래교육학회 2019 미래교육연구 Vol.9 No.3
The purpose of this study was to analyze the meaning of the instructional experiences of preservice teachers having the experience of blended PBL instruction in college. A survey was conducted on 128 students at a college located in an urban community, and data were gathered to make a qualitative research including reflective journals, this researcher's journal and e-instruction materials. As a result of making this study, PBL was found to have the largest effect on "problem-solving skills," followed by "cooperative learning skills," "communicative competency," "self-directed learning capabilities" and "learning motivation." In addition, the students gained positive experiences through blended PBL instructions: "Feeling great as a motivated learner and significant activities," "feeling a sense of achievement through self-directed learning," "flexible thinking and extension of thinking," "better self-understanding and greater confidence." It suggests that blended PBL instruction is closely associated with the development of the competencies of talented people who will take the initiative in the future era of the 4th industrial revolution, To ensure the efficiency of blended PBL instruction, the kind of instructional design that could maximize the strengths of online and offline instructions is necessary, and the active participation of the learner and the teacher's role performance as a facilitator and guide are required as well. To make them happen, various kinds of support need to be provided sufficiently in consideration of the characteristics of teachers who intend to conduct blended PBL instruction. 이 연구는 대학교에서 블렌디드 PBL 수업을 경험한 예비교사들의 수업경험에 대한 의미를 분석하고자 하는데 주 목적이 있다. 연구를 위해 G시에 소재한 K대학교 재학생 128명을 대상으로 설문을 실시하였고 질적 연구를 위해 성찰일지, 연구자일지, e-class 탑재 자료 등을 통해 자료를 수집하였다. 연구결과 학습자의 주요변인별 블렌디드 PBL 효과는 ‘문제해결 능력’, ‘협동학습 능력’, ‘의사소통 능력’, ‘자기주도학습 능력’, ‘학습동기’ 순으로 높게 나타났다. 또한 블렌디드 PBL 수업을 통해 ‘학습의 주체자로서의 뿌듯함과 의미 있는 활동’, ‘자기주도학습에 대한 성취감’, ‘유연한 사고 및 사고의 확장’, ‘자기이해 및 자신감 향상’ 등 긍정적인 경험이 이루어졌다. 이는 블렌디드 PBL 수업방법이 4차 산업혁명 시대의 미래를 주도할 인재의 역량 제고와 깊은 연관성이 있음을 시사한다. 효율적인 블렌디드 PBL 수업을 위해 온·오프라인의 장점을 극대화할 수 있는 수업설계, 학습자의 능동적 참여, 그리고 촉진자, 가이드로서의 교수자의 역할 등이 더욱 요구되어진다. 이를 위해 블렌디드 PBL 수업을 적용하려는 교수자의 특성을 고려한 다양한 형태의 지원이 충분히 이루어질 필요가 있다.

인쇄출판에 의한 도서의 이용형태는 정보화사회와 더불어 기하급수적인 전자매체로 대체되었다. 대학도서관에서는 이러한 인쇄매체와 전자매체 자료들을 어떻게 수집, 축적, 보존하느냐의 문제가 대두되었고, 이용자 집단의 특성에 맞추어 서비스하게 됨으로서 대학도서관 조직의 변화를 가져왔다. 이러한 환경변화에 따라 효율적인 서비스를 제고하기 위하여 이용자의 요구를 분석하였다.

In this paper, we introduce the automatic speaker identification system ‘SPO(Supreme Prosecutors Office) Verifier’. SPO Verifier is a GMM(Gaussian mixture model)-UBM(universal background model) based automatic speaker recognition system and has been developed using Korean speakers’ utterances. This system uses a channel compensation algorithm to compensate recording device characteristics. The system can give the users the ability to manage reference models with utterances from various environments to get more accurate recognition results. To evaluate the performance of SPO Verifier on Korean speakers, we compared this system with one of the most widely used commercial systems in the forensic field. The results showed that SPO Verifier shows lower EER(equal error rate) than that of the commercial system.

김경화 대구효성가톨릭대학교 1996 연구논문집 Vol.53 No.1
This paper deals with the discourses developed by german feminists, which are focused on finding the common experences of women as victims of "Nazi-Patriarchy". Early in the 1980's, german feminists pointed out that traditional studies on Nazism are based upon male-centered values which conferred dominance of men and subordination of women. They argue that women's experience systematically differs from the male, and that sidtinctive aspects of women's experiences can provide resources for the construction of more represesntatively understanding of women's lives in Nazism. They attempt to demonstrate that women's politics and patriarchal ideology im National Sozialism confinde women to subordinated position in the private and public sectors. However, their studies on nazism are grounded on partial experience of german arian women, and cannot count for dominance and subordination between women. This tendency is due to not only the white women-centered perspective, but also the dichotomous epistemological standpoint. This article purses two complementary project. On the one hand, it contributes to the feminist "deconstructive" project. It identifies how white women-centered perspective has shaped the most fundamental thought in feminist research of Naziwm. On the other hand, this paper begins "reconstructive" project. It show what is required in sudy on Nazism to make women's multiple experiences into a foundation for a more adequate and truley feminist theory.

시몬느 드 부브와르의 실존주의 페미니즘과 여성학사적 의의
김경화 대구효성가톨릭대학교 1997 연구논문집 Vol.56 No.1
In fact, Simone de Beauvoir's The second Sex has within a short thirty-year span achieved the status of a brilliant classic in the feminist studies. Thus, no introduction to feminist studies would be nearly complete without argumentation of this work, which has helped many feminist papers comprehend the full significance of women's second human condition. This paper is an sttempt to understand the meaning and validity of Simone de Beauvoir's Eistentialist Feminist in the history of feminist Research. This thesis deals with the essential questionof feminist theory as, Why is woman the second sex? There have been two kinds of approaches to the subject: the liberal and Marxist perspective. The former accentuates the female subordination which is rooted in a set of custormary and legal constraints that blocks women's entrance and success in the so-called public world. On the countrary, the letter analyzes the materialistic production process and regards sexual oppression as a by-product of class relation determined by the mode of production. Simone de Beauvoir believes that neither her liberal nor her Marxist sisters have gone far enough. These sisters tend to be either too subjective or too objective, and thus view the subject and the object as separated from each other. The present study, in this regard, aims to show existential method developed by Simone de Beauvoir, which tries to overcome such dichotomy in the flow of feminist notions and thoughts.
