농업유역 내 적절한 배수시스템 활용은 농업생산성 향상에 있어 매우 중요한 요소이다. 하지만 농업유역은 상·하류 간 공간적 비대칭이 존재하며, 배수시스템 작동에 있어 물리적 불평등을 초래하게 된다. 그 결과, 배수관로에서 가까운 농민들과 배수관로에서 먼 농민들은 배수시스템의 건설 및 유지관리에 있어 서로 다른 선호 양상을 띠게 된다. 이와 같은 이해 당사자들 간의 입장 차이는 농업배수시스템 유지를 위한 농민들 간의 협력을 방해하게 되며, 이로 인해 유역 내 배수시스템이 적절하게 작동하지 않을 경우 해당 유역 전체의 농업생산성은 감소하게 된다. 본 연구에서는 농민들의 인식 차이에 따른 배수시스템의 기능 정도가 유역의 농업생산성에 영향을 주게 되는 사회수문학적 현상을 반영하여 인간과 농업배수시스템을 결합한 사회수문모형을 개발한다. 나아가, 개발한 모형의 매개변수 변화에 따른 시스템 반응 관찰을 통해 인간과 농업배수시스템의 관계와 상호작용을 탐구한다.

In this paper, we analyzed the utilization trend of technology in the secondary mathematics textbooks based on the 6th, 7th and 2007 revised mathematics curriculums in Korea. We analyzed 30, 60 and 90 mathematics books based on the 6th, 7th and 2007 revised mathematics curriculums respectively. The analysis focused on three aspects of using technology, i.e., contents areas in which technology used, technological tools and programs used, and methods of using technology in teaching and learning mathematics. The results shows that the frequency of using technology in mathematics books has been increased as mathematics curriculum has been revised. In the mathematics books based on th 6th curriculum, only 25 scenes were found, but in 7th and 2007 revised curriculum 248 and 355 scenes were found. In the 6th curriculum, calculators and graphing calculators were used mainly, but in the 7th and 2007 revised curriculum many kinds of technological tools and softwares were used including CAS, dynamic geometry software, spreadsheets, programming language, and the Internet. Especially the internet was used frequently in the 7th curriculum. And the methods of using technology has been diversified as time passed. In the 6th curriculum, the technology mainly used for introducing technology and simple calculation, but in the 7th and 2007 revised curriculum the technologies and software were also used for understanding mathematical laws, principles and concepts and students-centered exploring the mathematical properties.

This study developed an educational program to help students athletes explore their career options. In preparation for when students in the athletic department do not succeed in sports, the need for career guidance in other fields of our society was emphasized, existing research was analyzed, requirements were identified, and a study plan was designed. Based on this, it was established a career exploration education program for records management system development in a step-by-step. Referring to previous research on career guidance in elementary, middle, and high schools, the study was conducted in the following 4 stages: analysis, development, desingn, application. In addition, students in the athletics department were able to learn more with interest by developing software related to their field. It is expected that this studyresearchwill contribute to eht divesification of research on career guidance for student athletes.

Problem-Based Learning is focused, experiential learning organized around the investigation and resolution of messy, real-world problem. It is both a curriculum organizer and instructional strategy, two complementary processes. The PBL model developed in this study was composed the two components of Problem Design(curriculum organizer) and Problem Implementation(instructional strategy). The basic process of Problem Implementation Model were composed the 8 steps ; 1) the identification of problem, 2) the specification of problem, 3) the exploration and generation for solution, 4) the selecting of best idea, 5) the specific planning of best idea, 6) the implementation and realization, 7) the evaluation, 8) the applying and reflection.

This article explores how we pursue and operate the English medium instruction(EMI) in engineering colleges so as to educate global engineers. Engineering students in the 21st century society need to have fundamental work in languages, cultural differences, and strategies for working with diverse colleagues. EMI is not sufficient for preparing our engineering students to cope with the changed environments in our globalized society. Based on the case study, we emphasize that EMI needs to be located in the context of global engineering education which demands our understanding of different cultures and communication practices. We also suggest some programs how we develop our EMI circumstances.

In this paper, we developed an augmented reality learning tool suitable for chemical bond learning and proposed a process-oriented guided inquiry learning using mobile augmented reality (POGIL-MAR) to find out how it affects science achievement, science learning motivation and learning flow. Participants were 139 10^th-grade students from a coeducational high school in Gyeonggi-do, and they were randomly assigned to the control group (TL), the treatment group 1 (POGIL), and the treatment group 2 (POGIL-MAR). They learned the concept of the chemical bond from the Integrated Science subject for four class periods. Results of two-way ANCOVA revealed that the POGIL-MAR group scored significantly higher than the other groups in a science achievement test, science learning motivation test, and learning flow test, regardless of their prior science achievement. In addition, in the case of the low-level group, the POGIL-MAR group showed a statistically significant improvement in achievement compared to the TL and POGIL groups. The MANCOVA analysis for sub-factors of science learning motivation show that the POGIL-MAR group had significantly higher scores in intrinsic motivation, career motivation, self-determination, self-efficacy, and grade motivation. In particular, the interaction effect between the teaching and learning method and the level of prior achievement was significant in the intrinsic motivation. Meanwhile, the MANCOVA analysis for sub-factors of learning flow show that the POGIL-MAR group had significantly higher scores in clear goals, unambiguous feedback, action-awareness merging, sense of control, and autotelic experience. Based on the results, educational implications for effective teaching and learning strategy using mobile augmented reality are discussed.

The purposes of the study were to examine engineering students' concerns and problems while they were choosing a project topic in interdisciplinary collaboration and to suggest ways to support them in an early stage of collaboration phase. To answer the research questions, we conducted a case study with engineering participants in GCTI 2015, an interdisciplinary collaborative and creative group project. Multiple data sources including focus group interviews, online survey and researchers' observation notes were used to triangulate research findings. We found four main concerns of engineering students. These concerns include (1) lack of self-efficacy, (2) limited resources, (3) lack of shared, meaningful, and common goals, and (4) lack of content knowledge. Based on these concerns we proposed four supports in an early stage of the collaborative project. These supports includes (1) implementing an orientation program, (2) providing opportunities for social interactions, (3) providing expert feedback, and (4) providing consultation for team building.

구문분석은 자연언어처리의 오랜 관심 분야로 다양한 접근방법과 알고리즘이 시도되어 계속 발전하고 있다. 하지만 기존의 접근방법은, 학습단계에서는 정답으로부터 추출된 이전 정보를 사용하고 평가 단계에서는 예측으로 이루어진 정보를 활용한다는 근본적인 차이가 있다. 이러한 차이를 극복하기 위한 다양한 시도가 있었고 그 중 동적 오라클 기법이 합리적인 시간 증가와 성능향상을 보였다. 본 연구에서는 이러한 동적 오라클 기법을 한국어 구문분석에 적용하였다. 동적 오라클 기법을 한국어에 적용할 때 고려해야하는 부분에 대해 탐구하고 실험을 통해 동적 오라클 기법을 한국어 구문분석에 적용하여 결과를 살펴보았다.

이 연구는 '맞다'가 의미론적 기본개념으로서의 진리에 대한 대체후보가 될 수 있는가의 물음을 배경으로 삼고 이 논문에서는 맞음의 개념이란 무엇인가라는 문제에 초점을 두고 다음의 다섯가지를 일차적으로 고찰한다. (1) '맞다'에 대한 일상언어분석을 통하여 이것은 두자 리 관계술어라는 점을 보이고 (2) 단어의 표면적 다의성은 그 반대어인 '틀이다'의 분석을 통하여 궁극적으로는 동일한 뿌리를 가지고 잇다는 것을 주장한다. (3) 맞음은 대칭적 논리구조를 일반적으로 가지지만 화자의 관심에 의해 비대칭적 구조를 가질 수도 있을 것이다. (4) '맞다'라는 단어를 해명할 수 있는 세가지 후보를 필요충분조건적 해석, 의미론적 접근, 표준론적 고찰에서 탐구하여 보지만 (5) '맞다'에 대한 진화론적 해석이 의미론적 기초개념일 수 있다고 생각하게 되었다.
