본 연구는 학습자 수준에 맞는 학습 내용과 평가 문제를 제공하고, 그 평가 결과에 기반하여 반복학습 및 심화학습을 효과적으로 제공하며, 차기 학습을 할 경우에 이에 기초하여 적절한 학습이 이루어질 수 있도록 하는 적응형 웹기반 교수 시스템을 제안한다. 이를 위해 코스웨어 설계시 학습목표의 중요도, 학습내용의 난이도, 학습목표와 학습내용과의 관련도에 따라 퍼지 수준 집합을 구성하고 이를 기반으로 학습자의 수준에 맞는 내용을 제공한다. 또한, 학습의 평가시에도 문제의 난이도, 평가문항과의 관련도를 고려하여 평가 결과를 제시하게 된다. 본 논문에서 제시하는 퍼지 집합에 의한 학습 내용의 제공과 평가 결과는 학습과정에 나타나는 여러 가지 다양하고 불확실한 요소들을 고려하여 처리함으로써 보다 융통성 있고 효과적인 교수 학습 방법을 제공할 수 있도록 한다.

국토해양부에서는 건설산업의 정보화 수준을 향상시키고 건설 생산체계를 효율화시키기 위해서 건설 CALS(Continuous Acquisition & Life-cycle Support)사업을 추진하고 있다. 건설CALS사업은 1998년부터 시작되었지만 건설CALS의 정보화수준은 어느 정도인지에 대한 측정이 없었다. 본 연구에서는 선행연구에서 도출된 평가지표를 사용하여 건설CALS의 정보화수준을 측정하였다. 연구는 설문항 및 표본 구성, 설문조사, 설문조사 결과 분석의 절차로 진행하였다. 설문조사 결과, 빠른 시스템 장애복구, 시스템의 웹환경 구축, 높은 표준분류체계 활용, 체계적인 정보전략 계획 수립 측면에서 우수한 것으로 판단된다. 본 연구에서 제시하는 결과는 건설CALS의 정보화수준을 정확히 파악하는데 기여할 것이라 생각된다.

The purpose of this study is to examine the difference between wife and husband in the level of stress recognition and distress subsequent to the life events, and thus 5 kinds of study questions have been established for the achievement of this purpose. Data were obtained from 371 couples who resided in Seoul through Likert-Type questionaire, and Frequency, Percentage, Mean, T-Test, One Way ANOVA, Pearson ${\gamma}$ Correlation, Multiple Regression, Cronbach ${\alpha}$ Coefficient were calculated. As the result of this studay, the experiences subsequent to life events, the level stress recognition and distress was different from wife and husband, and it was generally shown that those are higher for wife rather than husband.

The purpose of this study was to investigate the elementary and middle school students' understanding of observation, prediction, and hypothesis in everyday and science educational contexts. The questionnaires for testing understanding of three categories were developed, which obtained Cronbach alpha .91. It was consisted of 40 questions of 10 items related to observation, prediction, and hypothesis. Thy test was administrated to 868 subjects from grade 3 to grade 9. The results showed that the each level of their understanding of observation, prediction, and hypothesis ranged between $29{\~}58\%$, $43{\~}53\%$, and $10{\~}25\%$. The level of understanding of observation and prediction showed tendency to promote increasingly from grade 3 to grade 9, but the level of hypothesis did not.

Nurses play an important role in patient education, including providing patients with useful and appropriate information. The purpose of this study was to explore what particular types of information were important to women diagnosed with breast cancer. Sixty seven women with breast cancer an outpatient clinic in W Christian Hospital responded to the structured questionnaires developed by the investigator. Interviews and mail surveys were used in this study. The findings in this study showed that six kinds of information needs arose, ranked as the signs and symptoms of recurrence, the possibility of recurrence, the possibility of metastasis, treatment, diet and physical activities in daily living. Marital status, level of education, and level of monthly income were not related to level of informational need. Younger women rather than older women had a greater need to seek information(r=-.471, p<.01). There was a significantly negative relationship between duration of disease and the score on information needs(r=-.32, p<.05). The findings have implications that the opportunity to ask questions and have accurate information on the recurrence should be provided to women with breast cancer.

Virtuality is a product of the information age, and as it plays a larger role in the activities of individuals, groups and organizations, the issue of how human behavior varies between virtual and physical space has become one of the most important questions facing the management environment of today. The purpose of this article is to examine how virtuality shapes individuals' social relationships within and outside their work groups. We developed a conceptual framework that explores the links between virtuality and social network based on computer-mediated communication theory and social network theory. Using data from 172 individuals of 42 project teams in 5 global business consulting firms, we tested cross-level hypotheses. The results of hierarchical linear modeling (HLM) indicate that virtuality significantly influences individual's internal tie strength as well as external bridging ties. The results also show the effects of virtual process via CMC vary along with the virtual context.

This study investigates learners' perception on their engagement in rating activities in the EFL essay-writing context. The current study aims to address the answers to the following research questions: 1) What attitude do students show about their participation in the rating tasks? and 2) which of three aspects (e.g. the degree of rating experience, the exposure to English composition instruction and learning, and proficiency level) significantly influences learners' rating activities? 104 EFL learners participated in the rater training session. After participants finished rater training session, they rated three sample essays and peer essays using the given scoring guide. Based on the analysis of survey responses that students made, students showed positive attitude toward their engagement in rating tasks. For research question 2, only L2 writing proficiency seriously affected students' perception on the rating tasks. Advanced level of subjects did not feel stressed by a grade of peers as low level of subjects did. They were also critical about the benefits of self- and peer-assessment, suggesting that a peer's feedback on their own essay was not so useful and that a self-rating does not fully help learners identify their writing proficiency.

본 연구에서는 중학교 3학년 학생들의 공변 추론에 대해 알아보기 위해 학생마다 또래교수자와 또래학습자의 역할을 모두 경험할 수 있는 상호또래교수과정을 통한 교수 학습을 진행하였다. 학생들은 또래교수자로서 자신의 공변 추론을 가르치는 경험을 하고, 또래학습자로서 다른 학생의 공변 추론을 학습하는 기회를 제공받는다. 상호또래교수과정을 통한 교수 학습과정에서 비계가 제공될 수 있도록 이질집단으로 모둠을 형성하였다. 양적 그래프 유형 4문항, 질적 그래프 유형 4문항을 모둠에 제시하고 총 8차시에 걸친 상호또래교수를 진행하여 나타난 반응을 분석한 결과는 다음과 같다. 상호또래교수과정에서 학생들은 자신보다 높은 수준의 공변 추론 경험의 기회를 제공 받아 공변 추론 수준의 상승이 일어났다. 상호또래교수과정에서 학생들은 자신의 공변 추론을 수정하거나 보완하여 추론의 완성도를 높였다. 문제해결 결과의 피드백을 위해 최소한의 교사의 개입이나 수준 높은 또래의 중재가 필요함을 알 수 있었다.

In this paper, we propose a Korean speech understanding model using dictionary and thesaurus. The proposed model search the dictionary for the same word with in input text. If it is not in the dictionary, the proposed model search the high level words in the high level word dictionary based on the thesaurus. We compare the probability of sentence understanding model with threshold probability, and we'll get the speech understanding rate. We evaluated the performance of the sentence speech understanding system by applying twenty questions game. As the experiment results, we got sentence speech understanding accuracy of 79.8％. In this case probability of high level word is 0.9 and threshold probability is 0.38.

The purpose of this study was to analyze of career exploration and career decision-making by identity statuses(diffusion, foreclosure, moratorium, achievement) of vocational high school students. The research questions were formulated as follows. (1) Is there a difference in identity statuses by level of the career exploration? (2) Is there a difference in identity statuses by level of the career decision-making? (3) How much identity statuses-identity diffusion, identity foreclosure, identity moratorium, identity achievement-effect to the career exploration and career decision-making? 255 vocational high school students in Pusan were sampled. For the statistical analysis, Oneway, analysis of covariance structure by AMOS 4.0 was applied. The results of the study were as follows. (1) The identity diffusion was low in the level of career exploration, but the identity moratorium and achievement were high in the level of career exploration. (3) The identity diffusion was low in the level of career decision-making, but the identity achievement was high in the level of career decision-making. (4) The identity diffusion effected to negatively career exploration and career decision-making, identity foreclosure effected to low positively career exploration and career decision-making, identity moratorium effected to positively career exploration but negatively career decision-making, identity achievement effected to positively career exploration and career decision-making.
