인터넷의 발달과 함께 많은 학교들이 홈페이지를 운영하게 되었다. 학교 홈페이지는 온라인 상에서 이루어지는 학생과 학생, 학생과 교사 등 상호작용의 장으로서 그 역할을 담당하고 있고, 그 수단으로서 보드를 통해 생성된 게시판을 많이 이용하고 있다. 기존에 학교에서 사용되고 있는 게시판들은 일반 홈페이지에서 사용되는 보드를 이용한 것이 대부분이어서 학교상황에 최적화된 것이라고 보기는 어렵다. 본 논문에서는 사용자의 사용도를 중심으로 적응형 웹사이트를 구축할 수 있도록 지원해주는 학교용 웹보드를 설계하고 구현하였다. 특히 사용도를 평가하기 위한 알고리즘을 제시하고, 일반 학교에서 사용되고 있는 게시판을 분석하여 학교현장에 필요한 웹보드를 설계 및 구현함으로 사용자들은 쉽고 친숙하게 사용하고, 이를 이용한 학교홈페이지는 활용면에 있어 성과가 있을 것이라 기대된다.

최근 온라인교육의 필요성이 높아지고 요구 수준이 커짐에 따라 교육 서비스를 제공하는 시스템의 지능화된 처리능력이 필요하다. 퍼지신경회로망은 각각의 가중치(weight)를 갖는 채널로 연결한 망형태의 계산모델이다. 퍼지신경회로망을 학습시스템에 적용하여 학습자의 문항테스트 결과에서 학습과정을 재설정 할 수 있는 출력 값을 생성한다. 적응형 학습시스템은 퍼지신경회로망을 적용하여 개별화된 강의 코스로 학습을 진행하고 결과의 feedback을 통해 학습자의 최적 커리큘럼을 찾아내는 방법을 구현하였다.

E-learning is the application of e-business technology and services to teaching and learning. It use of new multimedia technologies and Internet to improved the qualify of learning by facilitating access to remote resources and services. In this paper, we show a computer-based test system, which is carefully designed and implemented. The system consists of a contents delivery mechanism, computer-adaptive test algorithm, and review engine. In this papepr, we describe what are points to be considered when design and implementing a computer-based test system. In addition, this paper shows how to control the bias value for computer-adaptive algorithm using real data.

Recently software complexity will continue to increase dramatically in the coming decades because of the dynamic and distributed nature of both data and applications. Not only must software systems assist in coordinating tasks among humans, they must also help mannage cooperation among distributed programs. Software agent may properly respond to these requirements. This paper investigates the adaptive characteristics found in adaptive tutoring agents. To funcion effectively throughout the range of situations presented by such a dynamic and extremely-distributed information entities, an agent must be highly adaptive. Adaptivity exists in several key aspects of agent's behavior to its dynamic situation. My goal is to show the various aspects of internal adaptivity that could be applied to build comprehensive agents that function effectively in tutoring agent system.

The purposes of this study are to find out the differences of parent-adolescent communication patterns, family cohesion and adaptability according to socio-demographic variables, to estimate the differences of family cohesion and adaptability according to parent-adolescent communication variables and to offer the basic data that are needed to improve desirable parent-adolescent communication, family cohesion and adaptability. Results of these analysis can be summarized as follows. 1. Open communication with father was showed significant difference according to adolescent's birth order. Close communication with father was showed significant difference according to adolescent's sex, adolescent's birth order and family type. Open communication with mother was showed significant difference according to adolescent's sex. Close communication with mother was showed significant difference according to adolescent's sex and birth order. 2. Family cohesion was significantly different adolescent's sex and income level. And family adaptability was significantly different adolescent's set adolescent's birth order and income level. 3. Family cohesion was influenced by open communication with father, open communication with mother, income level and adolescent's sex. And family adaptability was influenced by open communication with father, open communication with mother, close communication with father, income level and adolescent's sex.

몰입형 고품질 가상 현실 영상 스트리밍을 위한 360도 영상 부호화 및 전송 기술 중 하나로 사용자 시점 기반 타일 스트리밍 기법이 활발히 연구되고 있다. 360도 영상은 용량이 크기 때문에 개별 타일 기반 스트리밍 방법을 사용해 사용자 시점만 보내는 것이 효율적이다. 본 논문은 시점 기반 가상 현실 영상 복호화 시스템을 위한 복호기 적응적 타일 클러스터링 알고리즘을 제안한다. 제안하는 방법은 클라이언트의 복호기가 최대로 복호화 가능한 해상도를 탐색한 후, 사용자 시점 데이터와 복호기 적응적 타일 클러스터링 알고리즘을 이용해 클러스터화할 복수 개의 사용자 시점 타일들의 목록을 생성한 후, 타일 병합기를 이용해 타일들을 병합하여 클러스터 비트스트림을 생성한다. 이후 클라이언트는 병합된 클러스터 비트스트림들을 복호화한 후 사용자 시점을 생성한다. 제안하는 방법을 이용하면 클라이언트의 복호기 환경에 제약받지 않는 복호화가 가능하며, 제안하는 방법 중 하나인 4K_clustering 방법의 경우 8%의 복호화 속도 개선 효과를 얻을 수 있어 몰입형 고품질 가상 현실 영상을 위한 실시간 타일 스트리밍이 가능하다.

This paper presents a Web-based interactive and adaptive learning system that helps students learn the pumping lemma for the family of regular languages. Our system allows the students to proceed with their learning according to their individual differences through Web-Based Instruction and gives them opportunities for the interaction so that they can practice exercise related to the learning and gain feedbacks on the results of the exercises immediately. Especially, the system provides adaptive scaffolding that helps learners understand each step for the proof of the pumping lemma. Unlike existing systems that support learning the pumping lemma, the proposed system defines possible errors in advance and provides appropriate messages for corresponding errors. In addition, the system allows the learners to decompose a string into three parts so that they can understand the pumping lemma precisely.

The purpose of this study is to identify the types of subjectivity on communication styles of nursing freshmen by using the Q Methodology, and examine interpersonal relationship anxiety and college adjustment according to communication styles. Participants were 89 nursing freshmen, and data were collected from 7. March to 23. September 2016. Data were analyzed by using PC-QUANL program for communication styles, and using descriptive statistics, Mann-Whitney U test, Kruskal-Wallis test with SPSS windows version 24.0 program for interpersonal relationship anxiety and college adjustment according to communication styles. As a result, 4 communication styles were identified, 'Considerate-empathetic', 'Tense-passive', 'Vulnerable-easily distracted', and 'Facilitative-leading'. 'Tense-passive', 'Vulnerable-easily distracted' showed significantly higher interpersonal relationship anxiety than 'Considerate -empathetic'. 'Considerate-empathetic' showed significantly higher college adjustment than 'Vulnerable-easily distracted'. The result of this study is expected to be used for developing communication educational programs and provide a foundation to improve college adjustment of nursing freshmen.

The Korean society has been dramatically changed in its population, with rapidly increasing number of multicultural families through international marriages. The objective is to investigate the dietary patterns as an acculturation for multicultural families in urban area. The research target was 89 marriage immigrant females in Daejeon, in whom 50.6 % was in their twenties and 49.4 % was in their thirties to forties. 39.3% of the subjects was from China and 28.1 % from Vietnam, which showed similar pattern to the ratio of marriage immigrants' homeland in Korea. As age goes higher, cultural adaptation in Korea was the integration pattern. Marriage immigrant females from Vietnam showed the highest rates of marginalization pattern as cultural adaptation. Moreover, those with longer marriage duration and with children tend to show higher rates of integration pattern. 'Food attitude', 'food diversity', and 'balance life' as eating behaviors are related with acculturation. In conclusion, the multicultural families in urban area showed integration acculturation patterns, which could be influenced by their socioeconomic factors, such as residence period and Korean language ability and food diversity as dietary patterns factors. Further study with a quantitative analysis is needed in order to understand the effect of dietary patterns on acculturation in the multicultural families.

평가는 교수와 함께 교육 목표를 이루는데 있어 핵심적인 역할을 한다. 그렇지만 평가는 교수법의 발전 속도에 비교하면 상당히 느릴 뿐만 아니라, 교사는 물론 학생들에게 부정적으로 비추어지고 있다. 본 논문에서는 시험이 학생들을 동기화시킬 뿐만 아니라 그 자체로 중요한 학습 경험임을 강조하면서, 학습을 위한 평가를 활성화시키기 위해 테크놀러지를 이용한 평가 방식들을 소개하였다. 개발을 물론 어느 정도 연구가 이루어진 테크놀러지를 활용한 평가 기법을, 수행평가와 선다형의 개선안으로 대별하였다. 수행평가를 위한 기법에서는 논술채점, 지식 지도 제작법, 그리고 학습자 모형을 이용한 평가기법이, 선다형의 개선안으로 적응형 컴퓨터화 검사, 다중평가 및 변형선다형 방식이 각각 상술되었다. 결론에서는 평가를 통한 교육 효과를 극대화하기 위해서는, 교사는 물론 학생들의 평가에 대한 태도 변화 교육과 실제 교육 현장에서 쉽게 활용될 수 있는 컴퓨터를 이용한 평가기법의 개발과 보급의 중요성이 강조되었다.
