This study was executed to give a help in planning and implementing online learning. For this purpose this study investigated the effect of contents presentation types, levels and metacognition on concept map composition and learning process in online learning. Learning contents types were two, meaning-centered or context-centered. Contents levels were divided into two; basic or deficient. Metacognition was divided into two levels according to the scores of scale. Results showed that meaning-centered type(M=45.00, SE=1.97) got better scores in concept map than context-centered(M=34.71, SE=1.98), Presentation levels and metacognition had no significant influence on concept map. There were interaction effect(F=.002, p>.05) between presentation levels and metacogntion levels. The upper group in metacognition got higher score in deficient types whereas the lower group got higher score in basic type. In online learning process, learner's metacognition was an important factor to complement the contents' defect and lack.

This study investigates what older adults have image of older adult with relation to their self-identity. Fourteen participants are interviewed in this study. The main findings are as follows. Their response to image of older adult is divided in the form of 'denial' and 'accommodation' about social images of older adults. 'Denial' has 'total denial' and 'selective denial' while 'accommodation' includes 'acceptive accommodation', 'selective accommodation' and 'unwilling accommodation'. 'Total denial' indicates that the participants describe older adults very negatively, and they regard themselves as a person who is totally different from the older person they describe. 'Selective denial' represents that the participants have two types of older adults: negative and positive. They describe that they are close to the positive type of older adults themselves although they do not admit that they are older adults. 'Acceptive accommodating' does not describe older adults negatively, and they identify themselves as older adults. 'Selective accommodating' are very similar to 'selective denial' although the former differs from the latter in that they accept that they are older adults. 'Selective accommodating' also includes negative and positive types of older adults, and this type of participants admit that they are older adults, and believe that they belong to the positive type. In contrast to 'acceptive accommodating', 'unwilling accommodating' describes older adults very negatively. However, the participants belonging to 'unwilling accommodating' comes to accept that they are older adults due to irresistible realities.

This study investigated how latent groups depend on the longitudinal trajectories observed in fathers' involvement in parenting over a five year period, and the study also determined differences in children's behavioral problems and mother's parenting stress, marital satisfaction, and depression among these groups. By utilizing 1,316 sets of data from 1st to 5th Panel Survey of PSKC beginning in 2008, we examined the patterns of the latent groups and the differences among them. The results showed that, first, a changing pattern of fathers' involvement in parenting is classified into four groups: a low-stable group, a decreasing group. a middle-high changeable group, and a highest changeable group. According to the results of the latent groups, the fathers' involvement in parenting commonly started to decrease at the children's age of 4 years old. Second, problematic behaviors of children appeared more from the fathers in the decreasing group. Third, parenting stress, marital conflict, and depression were more often found in the low-stable group that in the decreasing group. the middle-high changeable group and the highest changeable group (in that order), while marital satisfaction showed a completely opposite pattern. Based on these results, political intervention and the future direction of research for fathers' involvement in parenting are needed in order to increase better behaviors of their children as well as the psychological well-being of their mothers.

The method of being composed of small groups has a strong influence on mathematics and cooperative learning and therefore, the group classification should be made in a way of considering not only a learner's cognitive factor but also a affective factor in order to maximize the effects. In this research, we regarded personality as the important standard of the group classification for cooperative learning and tried to find out the influence on the mathematical attitude and achievement in mathematics by means of conducting mathematics and cooperative learning according to the personality types. In order to resolve this problem, we performed the cooperative learning of small group subject to the students at year 6 in an elementary school by making up a similar personality type of group and a different personality type of group through MMTIC examination, and also tried to find out any significant difference in terms of mathematical attitude and achievement in mathematics between two groups. The results obtained in this research are as follows; First, organizing groups in accordance with personality types did not affect on mathematical attitude. Although there were some positive opinions towards mathematics and cooperative learning, the both similar personality type of group and different personality type of group showed no significant difference in terms of mathematical attitude between two groups. Second, organizing groups in accordance with personality types showed positive effects on the achievement in mathematics. The similar personality type of group showed the better achievement in mathematics than the different personality type of group.

The purpose of this study was to compare communication and mother-child interactions of reactive attachment disordered children with normal children. The subjects were 24 children and their mothers participated in this study'12 reactive attachment disordered children and mothers, 12 normal children and mothers. The mother and her child were brought into a p]lay room and the mother was instructed to play with her child as she normally would at home. The play situations were videotaped. Tapes were transcribed and transcribed data was analyzed with 13 mutually exclusive categories encompassing pragmatic functions represented in communication form the early stage of multiword speech in childhood. The tapes were analyzed with 10 behavioral mother-child interaction patterns. As the statistical method, t-test and correlation was calculated. The results of this study were as follows : 1) Reactive attachment disordered children used significantly fewer 'filler', 'information', 'requests', 'describes' and 'disscus self'. 2) Reactive attachment disordered children's mother used significantly fewer 'filler' and 'names'. 3) Reactive attachment disordered children used significantly more 'independent play', fewer 'intiates interaction', 'responsiveness' and 'answer' Reactive attachment disordered children's mother used more 'control play', 'observe' and fewer 'initiates interaction'. 4) Children's communication patterns were related lo mother·'s communication and mother-child interaction types. Children's 'filler', 'information requests', 'describes' and 'disscus self' were consistantly related to mother's 'filler' and 'names', (Children's 'filler', 'information requests', 'describes'. 'disscus self' and mother-child's intiates interaction 'responsivness' were significantly positively correlationed and 'independant play', 'control play', 'observation' were significantly negatively correlationed. The results of reveal that communication and mother-child interaction pattern of reactive attachment disordered group was different from normal group and children's communication pattern were influenced by mother's communication and interaction patterns.

The objective of this study is to explore audience perceptions of and responses to broadcasting deliberation and analyze their characteristics. The study employed factor and cluster analyses to categorize audience perceptions of broadcasting deliberation, resulting in the identification of six types of preferences: strict standards applied to positive deliberation etc. The results indicate that audiences, which can be categorized into three types, are more likely to prefer positive deliberation over broadcasting codes. The ratio of civil compliance to a minimum standard of positive deliberation is higher than ratios involving the other standards that were included in the study. The study applied a range of theories, such as cognitive dissonance, inconsistency of perception and response, and psychological reactance, to examine and distinguish audience perceptions and responses. The study's findings provide valuable information for researchers and interested organizations and can help to lay a cornerstone for systematically classifying audience perceptions and needs in the future.
