셋탑 박스와 같은 내장형 타겟 시스템의 자원 제약으로 인해 내장형 실시간 응용을 효율적으로 개발하기 위해서는 원격 호스트 상에서 동작하는 응용 개발 도구가 필요시 된다. 본 논문에서는 호스트 상의 원격 디버거, 대화형 쉘, 자원 모니터와 같은 응용 개발 도구들의 타겟 접근을 최소화하고 통신 채널을 하나로 유지하기 위해 호스트와 타겟 간의 중개자 역할을 하는 타겟 서버를 설계 구현한 내용에 대해 기술한다. 우리가 개발한 타겟 서버는 호스트-타겟 통신 방식, 실행 모듈 형식에 독립적인 구조이며, 도구의 확장성을 고려하여 Open API를 제공한다.

현대건설의 후원으로 교수 30명으로 구성된 중도지역방문교수단의 일원으로 Saudi Arabia, Bahrain 및 Kuwait에서의 현대건설의 작업현장을 시찰한 후, 필자는 약 2주일 예정으로 현대중공업의 전기사업부의 사람들과 더불어 북구제국에서의 전기공업시찰의 길로 떠났다. 필자로서는 첫 경험이 될 스웨덴의 ASEA와 서독의 Siemens 및 AEG-TELEFUNKEN계열의 공장과 연구소 시찰계획은 서울출발때부터 본인으로 하여금 여러가지 공상을 갖게 하였다. 짧은 시간이나마 중동지역 및 스웨덴과 서독에서 필자이 눈으로 직접보았고 그곳 회사중역 혹은 투사들과의 대화를 통하여 얻은 단편적인 이야기를 잡기형식으로 기술하고자 하나 독자들에게 혹시 지루한 감을 주지 않을지 염려된다.

영상회의 시스템과 같이 그룹의 멤버들이 서로 다른 지점에 위치하면서 실시간으로 대화하는 시스템을 실시간 분산 그룹웨어 시스템(real-time distributed groupware system)으로 정의한다. 회의 관리는 영상회의를 원하는 사용자가 네트웍 상에서 현재 열리고 있는 회의세션을 검색하거나, 새로운 회의세션을 생성하여 영상회의를 시작시키거나, 앞으로 열릴 회의세션을 예약하거나 등의 서비스를 제공한다. 여기서 회의세션의 의미는 분산된 시스템들과 그 시스템의 사용자들이 하나의 그룹을 형성하고, 그룹내에서 클라이언트와 서버 형식의 상호작용을 하도록 하는 연결 고리로 정의한다. 본 논문에서는 이러한 서비스를 제공하는 회의 관리구조를 설계하였고, 앞으로 구현 및 확장을 할 예정이다.

The purpose of this research was to investigate the change of argumentation of middle school students when they participated in argument tasks with CASE(Cognitive acceleration through science education) programs. Students argumentations were divided into two categories; 'explanatory argumentation' and 'dialogic argumentation'. Several argumentation components were used in their argumentation. Among argumentation components, claim and ground took place more than half of argumentation components. The percentage of 'dialogic argumentation' was lower than the percentage of 'explanatory argumentation'. The percentage of 'dialogic argumentation' was getting higher during CASE intervention. CASE programs had more effect on symmetric group than asymmetric group, however it was unstable. In general, participation ratio in argumentation of the formal operational student was high and the ratio in argumentation of the transitional student was getting higher.

As Internet grows, many web sites have been built, therefore much information has been registered. Because the web sites have more information, it is more difficult that the user can find the information wanted. Therefore, to get information that user wants easily, the full-text engine may be embedded to the web site. This paper is about developing the help conversational agent for a user to find the information that he wants through conversation with agent. The proposed method is based on the pattern matching of artificial intelligence, not natural language processing. If a user inputs any sentence, the help conversational agent responds to the sentence through preprocessing and pattern matching with knowledge. The knowledge is built with the XML format. With the approximate pattern matching, the agent picks up the appropriate response with some degree of similarities. At the experiment, some different sentences with the same meaning have been entered, then the agent recognized them as the same pattern, and it made a correct answer.

The purpose of this study was to explore the characteristics of children's interactive learning focusing on the Vygotsky's ZPD (the zone of proximal development) in a natural history museum as a representative free-choice learning context. We focused on the understanding of peer dyadic discourses and data were collected from 13 peer groups of children (3rd and 4th graders) who were videotaped all conversations occurred as they visited around the exhibits with no predetermined path. The transcribed data were analyzed by the developmental level of ZPD system and the discourse within an ADL (an actual developmental level) was overwhelmingly common in the conversations between child-child dyads. The representative discourse by discourse types were parsed according to three constructs of ZPD. Children formed the intersubjectivity through semiotic mediation such as conversations and exhibits and ended up with the similar situation definition. In conclusion, the details of discourses of the most impressive dyad were looked into focusing on the scientific concept. The study implies that a natural history museum becomes a meaningful resource to offer a deeper understanding of the nature of children's learning as an informal learning setting.

Gemäß der lernerorientierten Didaktik und Methodik des deutschen neuen Schulfaches "Praktische Philosophie" studiert die vorliegende Forschung die Unterrichtsmethoden zum fruchtbaren Philosophie-, Essay- und Ethikunterricht. Sie stellt die Unterrichtsmethoden unter der Gliederung von 1) Methoden für die Einführung in den Unterricht, 2) die für den Hauptteil des Unterrichts, 3) die für den Abschluss des Unterrichts, 4) die für Strukturierung des ganzen Unterrichts dar. Der zweite Teil wird wiederum in die Methoden der Form vom Sprechen und Horen, vom Lesen und vom Schreiben unterteilt. Wegen der Einschränkung vom erlaubten Umfang für den Aufsatz wird diese Forschung in zwei Aufsätze geteilt. Der erste Aufsatz behandelte den Teil 1) und den ersten Unterteil des Teils 2). Als Methoden für die Einführung in den Unterricht stellten sich Partnerinterview, Brainstorming und Schneeball dar und als Methoden der Form vom Sprechen und Horen Fishbowl, Pro-Kontra-Argumention, Gruppenarbeit und das sokratische Gespräch. Dieser zweite Aufsatz stellt Lesekompetenz, Lesestrategie, Textanalyse, Mindmapping, Dilemma, kooperatives Lesen und Placemat im Bezug auf Methoden der Form vom Lesen dar und das einfache und dialektische Argumentieren, das kreative Schreiben und Gedankenexperiment als Methoden der Form vom Schreiben. Als Methoden für den Abschluss des Unterrichts werden Blitzlicht, Feedback und Postersession und als Methoden für Strukturierung des ganzen Unterrichts Sandwich und Lernstop betrachtet.

Web access sequence mining can discover the frequently accessed web pages pursued by users. Utility-based web access sequence mining handles non-binary occurrences of web pages and extracts more useful knowledge from web logs. However, the existing utility-based web access sequence mining approach considers web access sequences from the very beginning of web logs and therefore it is not suitable for mining data streams where the volume of data is huge and unbounded. At the same time, it cannot find the recent change of knowledge in data streams adaptively. The existing approach has many other limitations such as considering only forward references of web access sequences, suffers in the level-wise candidate generation-and-test methodology, needs several database scans, etc. In this paper, we propose a new approach for high utility web access sequence mining over data streams with a sliding window method. Our approach can not only handle large-scale data but also efficiently discover the recently generated information from data streams. Moreover, it can solve the other limitations of the existing algorithm over data streams. Extensive performance analyses show that our approach is very efficient and outperforms the existing algorithm.

In this paper, we present the results of implementing an interactive lecturer introduction game that allows new students or freshmen to learn about their lecturer's information using a Digital Game-based Learning (DGBL) methodology. This game provides information such as the lecturer's name, photo, the courses that they teach in the form of a quiz game, with Unity and PHP used as the development environment. Communication between the game, Content Management System (CMS), and the database is by using the REST API, which enables the administrator to manage the content of the game such as score and number of questions for each level, user's password, and performance threshold, as well as the lecturer's information itself. Since the developed interactive game uses an integrated CMS, the content can be updated dynamically according to the situation, therefore, it can be easily applied to other departments, as well as other various educational games.

Didier Éribon's dialogue with Ernst Gombrich, first published in 1991 in France, stands as a curious example of interpreting a scientific mind into a popular narrative. On the occasion of its brand new translation in Korean, this essay examines the encounter of two different languages, that of scholarly art history and the other, of "entretien". Éribon's previous interviews with Georges Dumézil and Claude Lévi-Strauss have already shown the perfect use of dialogue that interprets in simple words some currents of European thoughts of 20th century at its highest level. The double identity found in the extraordinary profile of the author of The Story of Art should help us deal with this particular form of dialogue in depth, and expect another possibility of explaining and reconstructing academia.
