  • 중학교 '전기와 자기' 에 대한 개방적 탐구 과제는 관찰을 통한 서술적인 결과 처리가 특징인 정성적 과제와, 변인통제를 통한 정량적 결과 처리가 특징인 정량적 과제로 나눌 수 있다. 본 연구의 목적은 두 종류의 과제에 대한 중학교 2학년 학생들의 탐구 수행 특징을 탐구 과정을 중심으로 분석하는 것이다. 학생이 작성한 '탐구 보고서' 및 '탐구 활동 평가서' 그리고 연구자의 관찰 및 면담 자료를 분석하였다. 정성적인 과제에 대한 탐구에서는 자신의 생각과 다른 뜻밖의 관찰을 인지하고 처리하는 것이 어려운 점이었고, 정량적인 과제에 대한 탐구에서는 여러 개의 변인을 다루고, 신뢰롭고 타당한 측정을 하며, 정량적으로 결과를 처리하는 것이 어려운 점이었다. 정성적인 과제에 대한 탐구에서는 자신이 제시한 탐구 방법 및 결과의 부족한 점을 인지하고 있었는데 반해, 정량적인 과제에 대한 탐구에서는 부족한 점을 거의 인지하지 못했다. 이러한 결과는 기존의 실험실습과는 다른 개방적인 탐구를 지도할 때, 정성적인 과제의 경우 뜻밖의 관찰 결과를 신뢰롭고 타당하게 처리하도록 지도하는 것이 중요하며, 정량적인 과제의 경우 여러 개의 변인을 다루는 방법 및 신뢰롭고 타당한 측정 방법을 지도하는 것이 중요하다는 것을 시사한다.

  • The purpose of this research was to examine variables contributing to the father's role performance. The study has been designed to measure the quantitative(i.e. amount of involvement) and the qualitative(i.e. depth of affection/care) values in their modes of child-rearing practices by taking a clouter look at the father's views on their careers and on offspring. Subjects were 516 fathers of school-age children. Analyzing the factors that determine the quantitative and qualitative aspects of child-rearing practices by the fathers, the sense of fulfillment/value in life is the decisive factor behind the affection(i.e. qualitative) in the child-rearing practices. The resets indicated that the father's perceptions on their careers and on their children constitute the critical factors behind the qualitative and quantitative aspects of child-rearing practices, albeit holding such factors as the parents'working hour or as mothers with outside jobs under control.

  • As many organizations have adopted and implemented ERP systems, concerns about ERP performance also have increased. Former researches studied the ERP implementation of general large or medium size enterprises but there are not enough studies on ERP systems of a specific industry domain. In this paper, we introduce a case study on ERP adoption methodology of global leading company 'D' in shipbuilding and marine engineering industry. We examined ERP implementation background, method and scope and evaluated ERP performance in perspective of both quantitative and qualitative approaches. Quantitative research usually examines ERP performance based on financial statements and qualitative study typically examines organization change or improvement. As a result, ERP implementation in shipbuilding and marine industry can improve quantitative aspects such as cost, human resource and organization performance. As qualitative analysis, business process and tools can be unified and management transparency can be improved by ERP implementation. The result of this paper will be useful guideline for organizations which are considering ERP systems.

  • The various risk assessment methodologies have been introduced in the railway industries. The risk assessment suggested by CENELEC are described with two ways; quantitative and qualitative methods. However, in the industry application level, the quantitative method is hard to apply for a project because of somehow complicated or few statistical figures which was driven from the on-site and the qualitative method is too subject to have the confidence of its results fully. In this paper, the state-of-the-art methods which were suggested in Europe recently are introduced and compared to existing quantitative and qualitative methods. Furthermore, the application measures of railway projects are investigated.

  • 본 연구는 중학교 3학년 학생 2명을 대상으로 공변 추론 수준에 관련된 두 이론(Carlson et al.(2002), Thompson, & Carlson(2017))을 그래프 유형(양적 그래프, 질적 그래프)에 따라 분석하였다. 이에 대한 연구결과로 양적 그래프 과제에서 Thompson과 Carlson(2017)은 Carlson 외(2002)보다 학생의 수준을 세분화하였으며, 질적 그래프 과제에서 Thompson과 Carlson(2017)은 학생 수준을 범주화하기 어려웠지만, Carlson 외(2002)는 학생의 수준을 자세히 파악할 수 있었다. 이와 같은 연구결과는, 학생들의 공변 추론을 파악하는 데 있어 양에 따른 수치적 접근의 분석뿐만 아니라 두 양의 공변 양상을 비수치적으로 파악하는 질적 접근의 분석도 중요함을 시사하며, 또한 Thompson과 Carlson(2017)이 양에 따른 수치적 접근을 분석하는 데 있어 중요한 방법이며 Carlson외(2002)가 비수치적으로 파악하는 질적 접근을 분석하는 데 있어 중요한 방법임을 시사한다.

연구개발 프로젝트 정성·정량평가 비교 분석을 통한 성과평가 발전방향 연구 : K연구원 사례를 중심으로 (Comparison of a Qualitative and a Quantitative Approach to Evaluate the Performance of R&D Projects: A Case Study)

  • 본 연구에서는 정부출연연구기관 중 하나인 K 연구원 사례를 활용하여 연구개발 프로젝트에 대한 정성평가 결과와 정량평가 결과를 비교 분석함으로써 연구개발 프로젝트 성과평가 체계 개선을 위한 시사점을 도출하였다. 비교 분석을 위해 정성평가 결과는 국가과학기술연구회 규정에 따라 진행된 실제 평가결과를, 정량평가 결과는 연구개발 프로젝트의 산출물 데이터를 기반으로 자료포락분석(data envelopment analysis) 결과를 활용하였다. 비모수 상관관계 분석(Kendall's ${\tau}$)을 비롯한 다양한 분석 결과, 정성평가와 정량평가 결과 사이에는 분명한 차이점이 있는 것으로 확인되었다. 따라서 단순 정성 또는 정량평가로 연구개발 프로젝트를 평가하기보다 정성 및 정량평가가 상호보완적으로 진행된다면, 평가 시 각 연구개발 프로젝트의 특성을 반영함과 동시에 객관성도 보다 확보할 수 있을 것으로 기대된다.

  • This paper is a qualitative and quantitative study. The main purpose of the paper is to diagnose what makes English communication difficult at the Korean EFL adult level. In order to obtain data, this study employed interviews and a questionnaire. We identified thirty three factors blocking pathways to oral communication. Qualitative analysis repeatedly revealed patterns such as lack of grammar, lack of vocabulary, lack of background knowledge, and peer pressure, but quantitative analysis yielded somewhat different results: lack of colloquial expressions, lack of vocabulary, lack of various topics, problems in the educational system, difficulty in using existing knowledge, and lack of grammar. Findings which were common to both qualitative and quantitative analyses suggest that lack of linguistic knowledge and lack of background knowledge are major barriers learners encounter in communication. On the basis of the results, suggestions are made for overcoming these barriers.

  • This study performed qualitative and quantitative risk assessment of equipment for evaluating the protocol of hydrogen refueling stations and suggested measures to improve safety. Hazard and operability study was performed for qualitative risk assessment, and Hy-KoRAM was used for quantitative risk assessment. Through a qualitative risk assessment, additional ventilation devices were installed, simultaneous venting of the storage container was prohibited, and the number of repeated refilling of the evaluation equipment was identified to manage the number of fillings of the container. Through quantitative risk assessment, the area around the device was set as a restricted area when evaluating the station, and measures were suggested to reduce the frequency of accidents.
