This paper analyzes the effects of government-sponsored R&D on firm's employment and management performance, using the panel data of manufacturing firms in the area of Busan, Ulsan and Gyungnam. The paper applies PSM to estimate the treatment effects(ATT) without sample selection bias. The findings show that government-sponsored R&D in the area has positive effects on the participating firms' employment and R&D for several years after completing R&D projects.

질적인 측면을 충분히 감안하지 못한 양적 성과분석은 연구개발 과제의 성과를 제대로 반영하지 못하는 문제점을 안고 있다. 따라서 양적 성과와 질적 성과를 함께 종합적으로 고려할 수 있는 종합적인 성과분석지수를 개발할 필요가 있다. 본 연구에서는 주성분 분석과 동일 가중치를 부여하는 방식을 이용하여, 특허 출원 건수, SCI 게재논문 건수, 기술이전 건수라는 3가지 양적 성과지표와 이에 대응되는 특허 심사청구 항수, 논문게재 학술지의 IT, 총 연구비 대비기술료 비중의 3가지 질적 성과지표를 성과지표로 고려하면서 성과분석지수를 개발하고자 하였다. 주성분 분석의 적용 결과 특허 출원 건수(0.2160), SCI 논문게재 건수(0.1510), 기술이전 건수(0.1564), 특허 심사청구 항수(0.2257), 논문게재 학술지의 IF(0.2218), 기술료 비중(0.0291)의 가중치를 얻을 수 있었다. 이 6가지 평가지표는 종합평가지수라는 하나의 틀로 결합되어 개별 과제의 성과를 평가하는 데 활용될 수 있다. 더 나아가 양적 성과지표와 질적 성과지표로 구분하여 평가할 수 있다. 가중치 결정 방법에 따라 평가결과가 크게 달라지지는 않았지만, 가중치 결정 방법과 상관없이 양적 성과지표 평가결과와 질적 성과지표 평가결과는 크게 달랐다. 한 가지 흥미로운 점은 과제평가등급과의 상관관계를 따져보았더니 질적 성과지표와 과제등급과의 상관관계가 양적 성과지표와 과제등급과의 상관관계보다 더 크다는 것이다. 따라서 성과분석에 있어서 질적 성과지표를 반영한 질적 성과분석이 반드시 수행될 필요가 있다. 앞으로 특허 인용도 등 보다 다양한 질적 변수를 확보하여 성과분석지수를 보완할 필요가 있을 것이다.

고령화 혹은 국제화와 같은 변화 양상은 다가오는 21세기의 새 시대를 가치기준에서 뿐만 아니라 사회환경까지도 새로운 것을 추구하도록 요구해 가고 있다. 이것은 도로교통에 있어서도 마찬 가지로 지금까지 양적인 팽창 위주로 전개되던 것이 효율을 중시하지 않으면 안 되게 되었으며 특히 20세기 후반들어 반도체 기술과 함께 급격한 발전을 거듭하고 있는 컴퓨터 기술은 정보 통신 기술과 함께 도로교통의 새로운 장을 열어 갈 것으로 예측된다. 21세기의 도로 교통을 생 각할 때, 차량 보급 대수의 증가와 함께 지금도 교통사고가 커다란 사회 문제로 대두되고 있는 추세로 볼 때, 중심이 되는 단어는 역시 '안전'과 '환경'이겠지만 그 가운데에도 교통 사고의 저 감은 무엇보다 시급한 과제라 할 수 있으며 대기 오염을 비롯한 물리적 환경의 개선과 보다 원 활하고 쾌적하게 달릴 수 있는 교통 환경의 실현도 중요한 과제가 될 것이다. 이 글에서는 이 러한 관점에서 21세기의 도로교통과 이를 이루어가기 위한 기술적 과제들을 살펴보고자 한다.

This paper is to discover selection indicator for academia-industrial cooperation R&D project. Existing Project lacks careful consideration for participant enterprise. But, This project must be focused on enterprise for the goal of project is to improve business competition. Therefore, we analyze the survey result of enterprise satisfaction and deduct the factor of satisfaction by statistical analysis like One-way ANOVA and Regression. The study says that collaboration time, the time of planning of commercialization, technology transfer and the level of goal achievement improve enterprise satisfaction. And it implies needs for plan of manpower input and commercialization at the selecting phase. This paper is significant that it can improve project system by satisfaction. We expect that this result is utilized by planning and management.

Students need to have opportunities to share their ideas with peers by taking part in the conversation voluntarily that is, by persuading others and reflecting the consequences. Recognizing the importance of this point, this study intended to examine students' argumentation occurring in the process of performing tasks in the math classroom. Also, it tried to explore the types of the argument that students used in the classroom and the reason why they employed them with a focus on 'rebuttal', which is one of the six elements of the argument scheme such as claim, data, warrent, backing, qualifiers, and rebuttal. The analysis of argumentation is based on the five argumentation schemes suggested by Verheij(2005). The experimental class was conducted twice a week with four participants who are third grade middle school students. In the argumentation class students were promoted to address two different kinds of geometrical tasks. After the second session of class, the researcher conducted the semi-structured interview. Accordingly, this study contributes to the existing research by making students to have concrete and active argumentation while obtaining the sound understanding of the argumentation.

In this study, we examine the cases of instructors who conducted subject management by understanding the learning patterns of convergence major students taking programming courses Therefore, we intend to find implications for the operation of SW curriculum for convergence majors in the future. In the programming class of the convergence major, students of various grades and majors take the course, and a survey was conducted to understand their learning patterns in a non-face-to-face environment. The instructor studied whether it would be possible to induce learners' participation in class even when face-to-face communication was not possible, and tried to operate the class by understanding the learning propensity of the learners. As there are many students who have maintained successful experiences in self-directed learning amid COVID-19, weekly assignments were set so that they could solve their own problems independently, and almost all students submitted assignments. This study is meaningful in that it studied students' learning patterns, task performance, and programming achievement by operating 'Machine Learning' subject to students of the convergence major in a non-face-to-face situation due to COVID-19.

The aim of this study were to investigate the process of national R&D project planning by using the industry quantitative analysis(especially supply-chain enterprise ananlysis). In the selection process of funding project, the role and significance of the industry analysis can be identified as the effective guideline of using this methodology. Across the study, the following is noted : the factors of R&D effectiveness and R&D necessity are found reliable and valid. On the other hand, the emptiness of supply chain and the positive effect of foreign trade balance did not influence the selection of project. The information gained from this study will help us to define better expectations and industry analysis employing to the National R&D Project Planning.

The purpose of this study is to offer the implication for elementary school mathematics teaching by analyzing teachers' reflection on the cognitive demands of mathematical tasks they give in class. During the setup phase and the implementation phase in math class, the researchers analyzed the change of cognitive demands on mathematical tasks and the factors which had influence on such changes. After teachers' reflection on teaching, the researchers analyzed the change of cognitive demands on mathematical tasks and the factors which had influence on such changes in math classes. As a result, before teachers' reflection on the cognitive demands of mathematical tasks, the higher-level demands of mathematical tasks had a tendency to decline. However, after teachers' reflection on the cognitive demands of mathematical tasks, higher-level demands of mathematical tasks were maintained.

The purpose of the study is to analyze the levels of cognitive demands and components of the reasoning process presented in the mathematical sequence section of three high school mathematics textbooks in order to provide implications for the development of reasoning tasks in the future mathematics textbooks. The results of the study have revealed that most of the reasoning tasks presented in the mathematical sequence section of the three high school mathematics textbooks seemed to require low-level cognitive demands and that low-level cognitive demands reasoning tasks required only a component of one reasoning process. On the other hand, only a portion of the reasoning tasks appeared to require high-level of cognitive demands, and high-level cognitive demands reasoning tasks required various components of reasoning process. Considering the results of the study, it seems to suggest that we need more high-level cognitive demands reasoning tasks to develop high-level cognitive reasoning that would provide students with learning opportunities for various processes of reasoning, and that would provide a deeper understanding of the nature of reasoning.
