Entering upon 21th, the internet which bring the digital era, are changing the paradigm of education and cultivating creative and challenging person, which is the core of competitive power in knowledge-information society, is more emphasized than ever. To meet the needs of the present times, it has been concentrating its effort to improve learning-environment using e-Learning in the field of teaching. E-schoolbooks that were introduced recently by way of showing an example are representative case of this intention. Though many e-learning contents are being developed, the more speedily a society grow, the shorter the life of contents are. Moreover, the contents developed are impossible to use directly for tele-education system, so standard types adjusted for various kind of system are showing up. Among them the leading standard type is SCORM(Sharable Content Object Reference Medel) made in ADL(Advanced Distributed Learning) Corporation. The KERIS' Cyber Home Education System adopted this and is using it. So, in this study, we set the goal at designing and developing an e-learning contents and an experiment-focused mathematics that suit the KERIS' Cyber Home Education System on the basis of SCORM.

In constructive view, acquiring knowledge is made by experiences among members or elements. The knowledge in e-learning system can be extended up to knowledge of teachers and knowledge. of operating managers. We have many difficult problems to develop and manage e-1earning system because demanders on e-learning system have various. requirements. In traditional education system demanders are learners but in constructive view demanders can be extended to learners and teachers, operating mangers on e-learning system., In this study, we design and implement e-learning system named kedu V.1. Kedu V.1 is developed considering interactions of extended demanders of e-learning system in constructive view. And this system based on Linux operation system and MySQL, PHP. Also this system have efficient transplantation and portability capabilities and reduced cost and labor in implementation of real e-learning system

The purpose of this study is to investigate determinants of partner opportunism in Korean discount store distribution channels. In addition, this study also try to examine moderating role of relational learning in the relationship. This study deals with transaction specific investment asymmetry, mutual hostages, payoff inequity, cultural diversity, and goal incompatibilities as determinants of partner opportunism. For empirical testing, 293 respondents of suppliers of discount store in Korea were surveyed and the analysis utilizing partial least square model indicated that TSI asymmetry, payoff inequity, and goal incompatibilities had positive effects on partner opportunism. On the other hand, mutual hostages had negative effect on partner opportunism. In addition, relational learning had moderating effect on the relationship between TSI asymmetry, mutual hostages, and payoff inequity and partner opportunism.

There is a need for education that can be effectively education rather than one-sided audiovisual-oriented education. Serious games capable of contextual design and iterative training of various scenarios are easy to use and spread contents. The effects of safety education in childhood and adolescence, which are the most active periods of cognitive development, are most effective compared to other age group. The purpose of this study is to propose the guideline and components of the contents development for youth safety education using functional games.

농축업에 ICT 기술을 접목한 스마트 팜은 생육환경을 자동으로 조절하여 노동력 등을 줄이고도 생산성과 품질을 향상시키는 것이 큰 장점이다. 하지만, 수익으로 이어지는 출하량과 품질 유지를 위해서 병충해에 주의를 기울여야 함은 여전하다. 따라서 토마토 잎 병충해 발생 시, 적절한 대응을 통해 더 큰 피해를 막을 수 있으므로, 초기 증상을 포착하는 기법을 개발한다. 오픈 데이터 셋인 Ai hub 의 시설작물 질병 데이터셋과 추가로 확보한 샘플을 포함해 2 개의 충해, 4 개의 병해에 1,231 장으로 데이터셋을 직접 구성해서 학습했다. 객체 탐지와 세그먼테이션이 동시에 가능하며 작은 병변도 잘 탐지하는 모델을 사용해서 총 6 가지 병충해에 대한 뚜렷한 증상 탐지를 보여주었다.

개체명 인식은 정보 추출의 하위 작업으로, 문서에서 개체명에 해당하는 단어를 찾아 알맞은 개체명을 분류하는 자연어처리 기술이다. 질의 응답, 관계 추출 등과 같은 자연어처리 작업에 대한 관심이 높아짐에 따라 세부 분류 개체명 인식에 대한 수요가 증가했다. 그러나 기존 개체명 인식 성능에 비해 세부 분류 개체명 인식의 성능이 낮다. 이러한 성능 차이의 원인은 세부 분류 개체명 데이터가 불균형하기 때문이다. 본 논문에서는 이러한 데이터 불균형 문제를 해결하기 위해 대분류 개체명 정보를 활용하여 세부 분류 개체명 인식을 수행하는 방법과 대분류 개체명 인식의 오류 전파를 완화하기 위한 2단계 학습 방법을 제안한다. 또한 레이블 주의집중 네트워크 기반의 구조에서 레이블의 공통 요소를 공유하여 세부 분류 개체명 인식에 효과적인 레이블 임베딩 구성 방법을 제안한다.

This study examined the effects of constructivist educational beliefs and self-regulated learning skills of children on teacher professional development. The study was conducted by sampling 273 teachers. Three kinds of variables, which included constructivist educational beliefs, self-regulated learning ability, and professional development level were measured and analyzed for this study. The results were as follows. First, early childhood teachers beliefs of constructivist education, self-regulated learning ability and professional development were found to be higher than average. Second, the professional development of early childhood teachers is shown to be correlated with constructivist educational beliefs and self-regulated learning ability. When constructivist educational beliefs and self-regulated learning ability scores increases, the professional development score is high. Third, metacognitive strategies, cognitive strategies and constructivist educational beliefs are factors that predict the professional development of early childhood teachers. According to results of this study, it suggests that constructivist educational beliefs and self-regulated learning ability are important factors to be addressed.

The purpose of this study is to develop a communication model of teaching-learning at culinary practical learning class in school. Statistically, the organizational culture of culinary schools was influenced by the nature of hierarchical culture, task outcomes, and the conservative culture of organizations in companies. First, in basic skill class, teaching and learning methods are based on a teacher who leads students according to his plans and decisions. Second, in a higher skill course, teaching and learning methods are based on students who take an active part by injecting some fresh ideas into their class. Third, the model of three courses for culinary skill development has an effect on processing into a modeling-scaffolding-fading method by teaching and learning in school. It was ascertained that organizational culture directly or indirectly influenced organizational effectiveness and organizational culture in culinary schools. Moreover, it was found that organizational culture was the biggest influencing concept for communication effectiveness between teachers and students.

Recently, the importance of team based learning has emerged as the method for conducting the constructivist learning theory. College students, however, have the low preference toward team projects. Thus, this research suggested that the information literacy education should be designed to overcome the problems in team project activities after analyzing the college students' information problem solving process. The in-depth interviews were conducted twice with 10 subjects. As a result, the main problems during team project activities were task definition, judgement on relevant information, evaluation of result and process, absence of accountability and synthesis. The recommendations for information literacy course are as follows: introduction to different types of information sources, support for communication problems between team members, education of credibility judgment on information and criteria for evaluating the results.

The purpose of this study is to analyse the Big6 model and the Big6 modification model to find out the characteristics of the Big6 model and to derive implications for applying the Big6 model in the field. For this purpose, the information literacy standards of the AASL and the ACRL were compared with the Big6 model. The Big6 model, influenced by Bloom's taxonomy was analyzed alongside the Big6+3 model, the Big8 model and the modified Big6 model, provided by LG Science Land. As a result, the Big6 model could be used as an information problem-solving model, metacognitive activation strategy, and scaffolding to improve students' information literacy. In addition, it could be used as a model for constructivism, inquiry-based learning, the integration of curriculum, collaborative education, and ICT technology. How teacher-librarians or librarians apply the Big6 model is related to the improvement of critical thinking skills. Teacher-librarians and librarians need to plan situations, subjects, topics, and methods in a systematic and specific way when applying the Big6 model to the information literacy curriculum.
