This study focused on the fact that limitations of implementing school-centric models and standards of information literacy construction. This study was conducted with the purpose of developing and validating an instructional model to effectively design and practice online information literacy instruction for upper elementary school students based on a public library. Through a review of prior literature and analysis of current status and cases, a primary model was developed including the definition and area of information literacy, learning stages and activities, conceptual and procedural model, and teaching and learning plan. In addition, the first and second expert surveys were conducted to evaluate the internal validity of the model. The final model was derived by synthesizing and converging the collected opinions. As a result of the study, the final model consisted of 7 areas: 'Information literacy concept', 'Instruction component area', 'Conceptual model', 'Procedure model', 'Design principles and detailed guidelines', and 'Learning Steps and Activities' and 'Teaching and Learning Plan'.

Circular motion has been one of the most difficult concepts for students to understand. To facilitate for students to form scientific mental models about circular motion, this study developed 4M learning cycle teaching model based on the integrated mental model theory and strategies. For this study, fifty-three eleventh graders at a technical high school in Inchon were taught for 3 class hours. We conducted tests of basic physics concept and mental model of circular motion before, after, and two months after instruction. In results, we found that there were statistically significant improvement in the test of basic physics concept and mental model related with circular motion after instruction. Especially, this teaching model affected learning effectiveness of Correctness and Coherence of mental model.

Compared to corporate social responsibility(CSR) as business practices, government CSR policy have not been given much attention by researchers. This paper suggests drivers of government CSR policies and a conceptual model through examining concepts and social needs of CSR. The conceptual model encompasses three government roles: CSR vision setting, promoting and partnering. CSR can be useful to facilitate international transfer of clean technology, globalization of resource development companies, support for energy consumption of low-income classes. This paper concludes with summary and directions for future research focusing on areas of environmental and energy policies.

The study presents work information classification system of apartment house which can organize all construction management services throughout the planning and management of a construction such as the decomposition of the design process, the assembly of construction process and cost estimating, etc. In addition, the study suggested a way to connect work information classification system based on a relational database in working order and built a conceptual model for automated cost estimating by utilizing established data base. A conceptual model for automated cost estimating will resolve the fundamental problems of the existing cost estimating system and will be able to take advantage of scientific cost estimating system at the construction site of apartment house.

A questionnaire on "atomic models and electron configuration" was performed on 34 of 11th grade and 38 of 12th grade students who took the Chemistry-II course in order to examine the degree of learning achievement. Also eight Chemistry-II textbooks published in the 6th curriculum were analyzed for the similarities and differences in dealing with this topic and possible improvements were discussed in conjunction with the questionnaire. The results of this questionnaire showed that the degree of learning achievement on the topics between two different classes were not much different in general, although a little difference was found. This indicates that the topics have been taught in early 11th grade but subsequent supplemental teaching has not been performed. To study on the topics of "atomic models and electron configuration" effectively and systematically, knowledge on the basic spectroscopy and quantum mechanics should be preceeded. However this could be practically difficult under the current high school curriculum. Therefore It would be necessary to describe the basic concepts for the quantum mechanics and spectroscopy schematically in the "Reference Materials" section of the textbook, even if it is not very long. On the other hand, the Chemistry-II textbooks analyzed in this work reveal, in general, to have the similar organization and explanation modes. However it has been analyzed that a connection between the Bohr and electron-cloud atomic models might be insufficient or position of electrons might be possible to be misunderstood by students in some textbooks.

개념적 강우-유출모형에서 토양수분과 관련된 물리적 거동은 간략화 된 형태로 강우 및 온도자료를 활용하여 중간변량(state variable)으로 간접적으로 고려되고 있다. 특히 강우-유출모형에 초기함수 조건은 선행함수조건을 고려하여 수문지질학적 평가를 통하여 결정되어야 하나, 일반적으로 가정되거나 모형에서 간략화 된 분석과정을 통해 추정되고 있다. 본 연구에서는 토양의 Water Balance 모형 기반의 개념적 토양수분 추정모형을 활용하였다. 토양수분의 시간적 변동성을 평가하는데 있어서 연속적으로 측정된 In-situ 토양수분 자료를 이용하여 모형의 적합성을 평가하였다. Green-Ampt 방법과 중력식 침투방법과 온도를 활용한 증발산 추정기법을 연계한 토양함수 평가 모형을 개발하였다. In-situ 토양수분 자료와 유역의 강수량 및 온도자료를 이용한 관련 매개변수를 Bayesian 기법을 통해 추정하였으며 매개변수의 민감도를 평가하여 제시하였다. 최종적으로 제안된 모형의 활용측면에서 강우-유출모형의 초기함수 조건으로써의 역할을 평가하였다. 구체적으로 첨두유량 및 유출고와 초기함수조건과의 관계를 제시하고 강우-유출모형에서 활용방안을 제시하고자 한다.

In this study, based on the analysis of FRBRoo, we tried to propose suggestions to expand and improve the FRBR family conceptual model. FRBRoo is a plug-in ontology of CIDOC CRM with cooperation of museum field. As FRBR family models also revised and integrated into IFLA Library Reference Model, the additional analysis on IFLA LRM was performed. If bibliographic information is required to support the technical and user services of the library, the way to analyze the bibliographic information should be improved in order to cope with the new challenges faced by the library. To do this, time-related event concepts should be reflected in the modeling of bibliographic information. It is also necessary to expand the creation and exchange unit of bibliographic information to smaller units or larger units than legacy bibliographic records. Using FRBRoo as a linkage tool for the sharing of bibliographic information is also suggested.

As the usage of computer and internet is growing, ICT-based teaching is required in education. So far almost web-based coursewares are learner-based individual teaching. Current learning theories and learning model in WBI are too focusing on courseware or too general to apply in education directly. In this view, learning model with subject-specific search engine might be a solution. In this thesis, we developed systematic concept learning model, promoting traditional concept learning to suitable model in education field and also, we developed CEhunt(Computer Education Hunter), that is computer education search engine providing the teaching materials and supporting the design of teaching and effective concept learning environment to learners. Also, we verified that this model could have a positive effect in systematic concept forming process of learners for subject concerned.
