This paper presents a model for supporting the adaptive interaction between the computer and the learner. To design an adaptive interaction model, the strategy to support the adaptive interaction in the web-based educational system was established. And then. the necessary components for executing each strategy were selected. Also. the logical relations among the components were verified. To verify the effectiveness of the proposed adaptive interaction model, we applied the existing web-based courseware and the new courseware using the adaptive interaction models to two groups respectively, and then measured the performance of each group. Experimental results reveal that the adaptive interaction model actually has positive effects on the learning activities of the learner.

본 연구의 목적은 초기~후기 청소년기의 학교적응력을 향상시키기 위하여 이에 영향을 미치는 가족 및 개인 요인과의 관계를 검증하고자 하는 것이다. 보다 구체적으로, 가족요인으로서 가족응집력과 개인요인으로서 자기효능감, 그리고 학교적응 간의 관계에 대한 연구모형을 설정하고 이들 간의 관계를 검증하고자 하였다. 이를 위하여 본 연구에서는 2010 한국청소년건강실태조사(Korean Survey on the Health of Youth and Children in 2010)를 통하여 9,844명의 제주도를 제외한 전국 초등학교 4~6학년생과 중 고등학생을 대상으로 수집된 자료에 대하여 구조방정식모형을 이용하여 그 적합도와 주요 변수들 간의 경로의 유의성을 확인하였다. 분석 결과, 본 연구에서 설정된 연구모형의 적합도는 양호한 것으로 나타났으며, 가족응집력은 자기효능감과 학교적응에 각각 정적으로 유의한 영향을 미치며, 자기효능감 역시 학교적응에 정적으로 유의한 영향을 미치는 것으로 확인되었다. 그리고 가족응집력과 학교적응 사이에서의 자기효능감은 통계적으로도 유의한 매개효과를 가지는 것으로 나타났다. 이러한 연구결과에 근거하여 학령기 청소년의 학교적응을 향상시킬 수 있는 개입 방안에 대한 함의를 제시하였다.

This study aimed to empirically test the causal model of stress-coping-adaptation for unwed mothers, which was built upon the Lazarus and Folkman's(1984) "Stress-Coping-Adaptation" model. In doing so researchers endeavored to provide practice implications as well as theoretical ones which would be helpful both to alleviate the unwed mothers' stress level, and to facilitate social adaptation of the unwed mothers. In order to fulfill research purpose data were collected from the national sample of 423 unwed mothers in Korea. The results showed that the overall goodness of the fit of the proposed causal model was excellent. Most of the path coefficients between social support, stress, coping, and adaption turned out to be statistically significant. The moderating effects of "pursuit of social support" between stress and adaption was not significant statistically, though. Implications and suggestions were provided to reduce the level of stress of the unwed mothers, and to facilitate the adaptation of the unwed mothers.

The purpose of this study was to investigate the casual relationship between school adjustment, self-esteem and life satisfaction and academic achievement in elementary school students. This study utilized the NYPI's longitudinal data collected on elementary school students nationwide for 2012. Equation Modeling analysis was used to analyze 2,254 5th grade students' data. It was found that school adjustment was positively correlated with self-esteem, life satisfaction and academic achievement. School adjustment was directly associated with academic achievement. It was also confirmed that school adjustment indirectly explained academic achievement through self-esteem and life satisfaction. Future research directions and implications to teacher and institutions were discussed.

In the actual case, a model of noise canceller using adaptive filter has both a channel transfer function from noise source to main signal input and to noise canceller input. The previous models of noise canceller have been considered to be only one side channel transfer function. Therefore, it is proposed that a new model has two channel transfer functions and derives an optimal tranfer function of adaptive noise canceller. The adaptive filter is using the joint process lattice filter that has fast adaptive speed. The signal noise radio has been improved by a model of ANC-ALE and it is confirmed with computer simulation. Beside, a dc bias is very effective for noise cancelling, especially to the particular signal.

This study designed a mediating pathways models to examine the theory, 'the influence of attachment relationship between adolescents and their parents affects on adolescents' psycho-social adjustment through the mediating variable of optimism'. Authors tried to examine if this theory is applied to group-home adolescents who live with surrogate care-givers instead of their parents. For this study, two models, 'Psychological Adjustment Model' and 'Social Adjustment Model' were constructed. Each model has path, 'Attachment with Care-givers → Psychological Adjustment' and ''Attachment with Care-givers → Social Adjustment' respectively. 'Optimism' is mediating variable in between these two variables. The results were very clear. In two models, no direct effects from 'Attachment' to 'Psychological Adjustment' and from 'Attachment' to 'Social Adjustment' were found. However, indirect effects from 'Attachment' to 'Psychological Adjustment' and from 'Attachment' to 'Social Adjustment' were statistically significant through the mediating variable of 'Optimism'. This study suggests that more research on 'Optimism' which has not been focused among social welfare researchers needs to be followed.

The purpose of the study was to estimate the trajectories of elementary school adjustment in grades 1 through 4. For the purpose, the Korean Children's Panel data were analyzed using potential growth model and the growth mixture model. As the result, the linear model was selected as the optimal model. The four potential groups were derived as trajectories: high-level maintenance, low-level maintenance, low-level increase, and high-level decrease. In terms of group distribution, the most children were in high-level maintenance group and then low-level maintenance, low-level increase, and high-level decrease in order. Based on the findings that trajectories of elementary school adjustment changes as children growth, we suggest that schools and families need to carefully investigate and support their school adjustment in individual levels.

Education is the largest application area of adaptive hypermedia systems. The user modeling is considered a very important part of the field of adpative hypermedia systems. In this paper we present the developed user model which provides different educational contents using a neural network. The user model has been verified on hypermedia for learning about basic web concepts, multimedia and HTML. This paper reports the results of simulation. Our simulation shows that the user model exactly can provide contextual different links for different students.

The purpose of this study was to investigate the relationship between child maltreatment, protective factors, and resilience in elementary school students. It was especially focused on what direct effect of the risk factor(child maltreatment) and protective factors to child resilience, and how protective factors affect the resilience of maltreated child. In the concrete, this study intended to find out whether protective factors mediate between child maltreatment and resilience. This study based on data from the first wave of 'Korean Youth Panel Survey(KYPS)' and subjects consisted of 2,844 4th grade elementary school students. In addition, to test the proposed models, the Mplus-structural equation modeling-was used. The major findings are as follows: First, when child maltreatment increased, resilience decreased. Second, when protective factors increased, resilience increased. Third, protective factors act as buffers against the negative effects of child maltreatment on resilience by mediation. Results indicated that child maltreatment related negatively to resilience and protective factors related positively to resilience. In addition, a mediational model in which protective factors mediates child maltreatment and resilience was supported. In conclusion, various theoretical and practical implications for social work practice focusing on the maltreated children were discussed.
