본 연구에서는 플랜트 잡음이 강한 음향 환경에서 기존의 인버스 필터링 방법에 적용 선형 증진기를 부착하여 부가경로 전달함수의 온라인 모델링과 주소음원에 대한 제어 시뮬레이션을 수행하여 다음과 같은 결과를 얻었다. 첫째로, 신호대 잡음비가 낮은 음향 환경에서 적응 선형 증진기를 이용하여 플랜트 잡음을 제거함으로써 부가경로 전달함수의 온라인 모델링을 수행할 수 있었다. 둘째로, 실제의 부가경로 전달함수가 변한 상태에서 제안된 알고리즘을 이용하여 제어 시뮬레이션을 수행하여 주소음원에 대한 제어와 정확하게 새로운 부가경로 전달함수를 예측할 수 있었다. 향후 본 연구에서 제안된 알고리즘을 실시간 어셈블리화하여 능동 소음 제어 실험한 결과를 발표할 예정이다.

Objectives: The objective of this paper is to study influence of self esteem, family support and adaptation to school life on adolscents' suicidal ideation adjsuted for general characteristics effect. Methods: Using cluster sampling, 318 high school freshmen from T city were extracted as survey subjects. Independent t-test, ANOVA, Duncan test, Pearson's correlation coefficients and multiple regression analysis were applied for statistical analysis. Results: Among general characteristics, religion, family income, single-parentedness, health status and school grades were statistically significant with suicidal ideation. Controlling the above variables, increase in self-esteem (${\beta}$=-.300) and family support (${\beta}$=-.267) showed statistically significant decrease in suicidal ideation but adaptation to school life did not. Conclusions: Therefore, it is proposed that measures for enhancement of self esteem and family support to be included in development of suicide prevention programs.

Purpose: The purpose of this study was to develop a program promoting adjustment to hospital life and determining its effectiveness for school aged children. Method: The sample group consisted of 76 hospitalized children in 2 University Hospitals located in Busan. The experimental group was given the program on admission and feedback was obtained on the 3rd day and again 24 hours later. Data was analyzed using t-test and ANOVA in the SPSS program package. Result: There were significant differences, in information(t=4.235, p=0.000) and coping effort criteria (t=2.922, p=0.005) between the experimental and control groups. There was a non-significant difference in attitude criteria between the two groups(t=1.009, p=0.316). Conclusion: It was found that the adjustment promoting program for hospital life for school aged children was effective, but not enough to promote self-esteem. The program, based on a learning theory, was improved and shown to be an effective and strong method to promote adjustment of school-aged children.

In the case of the transfer function for the secondary path is dependent on time, the on-line method which can model it is continuously must be applied to the active noise control technique. And the adaptive random noise technique among the on-line methods is effective in the narrow-band control. In this method, the signal to noise ratio between random noise for modeling and primary noise is low. Therefore, the estimations of transfer function will be prone to inaccuracies and the convergence time will be too long. Such imperfections will have an influence upon the performance of an active noise controller. In this study, t enhance the signal to noise ratio, the on-line method that is combined the conventional adaptive random noise technique and the adaptive line enhancer, is proposed. By using proposed on-line method, a rigorous system identification and control of primary noise have been implemented.

The purpose of this study is to examine the associations among family cohesion, self-efficacy, and school adjustment in adolescence. This study investigated these interrelationships using structural equation modeling. The results indicated that family cohesion had effects on school adjustment both directly and indirectly through self-efficacy. The mediating effect of self-efficacy was statistically significant. These results imply that family cohesion and self-efficacy need to be emphasized as a strategy to improve school adjustment among adolescents.

Due to the rapid development of computer technology, online learning using ICT technology is already quickly settling in our lives. Music education was conducted mainly in an offline-based environment, but research is being conducted to switch to online because there is no time and space constraint of online education and interactive education led by learners is possible. In this study, we propose design and implement an adaptive learning system to enable adaptive learning online among music education. This system has the following advantages. First, by providing an LMS-based platform, one can solve the social education problem corresponding to economic and geographical factors. Second, both objective learning feedback provided automatically by the online adaptive harmony learning system and teaching feedback. Third, learners can be provided with recommended answers to given harmony exercises. The adaptive online learning system of harmony will lead professors and learners to effectively teach and study.

Purpose: The purpose of this study was to examine the effects of the simulation-based cooperation program on self-efficacy, social problem-solving ability and college life adjustment of health college students. Methods: A nonequivalent control group pre-posttest design was used. Sixty-eight students were in the experimental group receiving the simulation-based cooperation program, and 68 were in the control group with no treatment. Results: There were significant increases in self-efficacy(z=-4.70, p<.001) and college life adjustment(t=2.03, p<.05) in the experimental group compared to the control group. However, there was no difference in the social problem-solving ability (z=-1.87, p=.061) between the experimental and control groups. Conclusion: The findings indicate that the simulation-based cooperation program has a significant effect on improving self-efficacy and college life adjustment in health college students. Thus the simulation-based cooperation program to promote the social problem-solving ability needs to be more developed and research related with cooperation program is further needed.

This study aims to examine the effects of teachers' critical consciousness on their attribution of cause and responsibility about multicultural students' school violence victimization and their prediction on students' school adjustment. To this end, we presented four scenarios depicting multicultural students' school violence victimization and measured teachers' critical consciousness, cause and responsibility attribution, and school adjustment prediction. Results showed that teachers endorsing higher levels of Egalitarianism tended to attribute causes and responsibility to situational factors, rather than to a multicultural adolescent being victimized by school violence. The levels of Perceived Inequality of critical consciousness did not have significant effects on these variables. Also, teachers with a higher level of Egalitarianism tended to predict multicultural adolescents' school adjustment more negatively. Based on the current findings, we discussed implications on teacher education for promoting teachers' multicultural competence, along with limitations and directions for future research.

도서관은 전통적으로 지식과 정보자료를 수집하여 보존하는 기능을 담당해 왔다. 그러나 현대 후기산업사회에 적응하기 위해서는 이러한 전통적 기능 외에 과학기술정보의 신속한 공급은 물론, 개인의 지적 활동과 문화향수 및 여가선용의 극대화를 도모하고, 특히 지역사회 주민들의 문화복지를 증진시키기 위해 도서관 프로그램을 적극적으로 활용토록 자극하는 사회문화적 역할이 더욱 강조돼야 한다. 공공도서관 업무의 문화부이관을 골자로 하는 '도서진흥법'의 시행으로 이제까지와는 전혀 다른 질적 변화의 계기를 맞고 있는 우리 도서관은, 과연 이같은 역할과 과제의 수행을 위해 어떤 노력들을 기울여야 할 것인가. 지난 도서관주간에 열렸던 학술대회에서의 논의를 정리한다.

맞춤형 이러닝은 학습효과의 증진을 위한 방안으로 개인 맞춤형, 개인화 혹은 적응화 등의 개념이 제안되고 확장되었다. 본 논문에서는 초기 선호도, 흥미도 혹은 검색습관을 고려하는 방식으로부터, 특정한 학습객체를 자율 선택하여 반복 학습할 수 있도록 개념단위를 적용한 방식, 학습자의 능력을 고려한 최적 난이도 학습객체를 제공하는 방식 등 다양하게 제안되고 있는 현대적 개인 맞춤형 이러닝 체계들을 비교 분석한다. 개별 시스템에 따라 '평가'에 국한되거나 '평가'와 '학습'을 연계하는 경우가 존재하며, 이에 따른 적용에 의하여 학습환경과 맞춤형 제공방식 및 학습효과를 상호 연계할 수 있음을 밝힌다.
