In this paper, we propose an adaptive tutoring system, which analyzes learning process, subject materials, and test items of students, diagnoses learning problems of them, and then gives proper advice accordingly. In the system, learning materials are constructed using concept map, on which the relationships among learning concepts are represented. Concept map can be used for several purposes in instruction process. Our work considers that new learning knowledge is dependent on what is already known. That is, it means that precedent concepts should be thoroughly learned for students to comprehend new concepts. After grasping the learning state of students for precedent concepts to be required before learning new concepts, our system provides proper learning materials for want of them, diagnoses the concepts which students have trouble to understand in the learning process, and provides suggestions for it.

Collaborative filtering systems based on ｛user-document｝ matrix are effective in recommending web documents to user. But they have a shortcoming of decreasing the accuracy of recommendations by the first rater problem and the sparsity. This paper proposes the automatic preference rating method that generates user profile to solve the shortcoming. The profile in this paper is content-based collaborative user profile. The content-based collaborative user profile is generated by combining a content-based user profile with a collaborative user profile by mutual information method. Collaborative user profile is based on ｛user-document｝ matrix in collaborative filtering system, thus, content-based user profile is generated by relevance feedback in content-based filtering systems. After normalizing combined content-based collaborative user profiles, it automatically rates user preference by reflecting normalized profile in ｛user-document｝matrix of collaborative filtering systems. We evaluated our method on a large database of user ratings for web document and it was certified that was more efficient than existent methods.

This study attempts to analyze fifteen computer textbooks for the first and second grades. The textbooks were analyzed by the following characteristics: goals, contents, and formative evaluation. Evaluation criteria from previous works were selected for advantages and identify the problems. In addition, advice for teachers using these books is proposed. The results of the analyses of current computer textbooks are the following: Firstly, in the area of goals and contents, most textbooks clearly define learning goals for each unit. Secondly, in the area of content, some textbooks have a large volume for first and second grade students, and they do not provide enough integration with other subjects. Finally, they do not provide formative evaluation to achieve for goals.

We developed $21^{st}$ century scientific literacy assessment instrument and applied it to explore the contents of seven Korean science textbooks. The $21^{st}$ century scientific literacy assessment instrument involved three dimensions (habits of mind, character and values, science as human endeavor). Each dimension consists of three sub-dimensions. Five science education experts assessed the content of textbook using criteria. We discussed issues in which the examiners responses did not match and reached an agreement on initial disagreement. As a result, we found that most Korean textbook contained contents on habits of mind, especially, communication, collaboration, and information management. We also found that most materials lacked information about character and values and science as human endeavor. Based on the result, we suggest that researchers and science educators need to consider all dimensions of the $21^{st}$ century scientific literacy when they develop curriculum and teaching materials. In addition, the rubric for $21^{st}$ century scientific literacy can be adopted as an assessment tool for examining curriculum, teaching materials.

현재까지 많은 공조용 빙축열 시스템이 전력수요 평준화를 목적으로 개발되어 설비에 적용되어 왔다. 지금까지 각종 학회에서 발표된 내용들은 기업에서 개발된 빙축열 시스템의 제빙 방식의 특징이나 시운전 결과가 중심이고, 빙축열 시스템의 평가, 특히 실제 설비의 운전 데이터에 기초한 시스템 성능 평가에 대한 내용은 많지 않았다. 이번에 소개하고자 하는 기술은 현장 제조형의 과냉각 방식 빙축열시스템의 실제 설비를 대상으로 제빙조의 제빙성능과 해빙성능에 관하여 모델해석를 기초로 평가하고, 제빙효율, 소비전력, 운전비용과 관련하여 설명함으로서 열원시스템을 평가하고자 한다.

Cognitive-pragmatic language ability decreases during the normal aging process. Evaluating the ability might be useful in testing predicting cognitive level and diseases such as dementia. The aim of this study is to analyze various assessment protocols for normal aging, and evaluate the content validity of the currently developing cognitive-pragmatic language test domains and items. Content Validity Index(CVI) was calculated based on ratings judged by 17 experts including speech-language pathologists and clinical psychologists. As a result, it was found that CVIs of all 7 domains including attention, memory, organization, reasoning, problem solving, executive function, pragmatic language were above .75. It was concluded that the test items contained the appropriate content validity to assess cognitive-pragmatic language for normal aging.
