This study examined how the relationship between grandmother-adult child solidarity, caregiving satisfaction, and grandmother's child-rearing role varies according to the relation with the grandchild. Mediation effects and moderated mediation effects were analyzed to investigate the relationship between these variables. The participants were 295 grandmothers raising preschool-aged grandchildren in the Seoul and Gyeonggi areas. Data was analyzed using SPSS 23.0 and PROCESS macro, performing correlation analysis and hierarchical regression analysis. The statistical significance of the indirect effect was examined using a bootstrapping procedure. The results are as follows. First, grandmother-adult child solidarity directly affects the grandmother's child-rearing role. Second, grandmother-adult child solidarity indirectly affects the grandmother's child-rearing role through caregiving satisfaction. Third, the direct and indirect effects of grandmother-adult child solidarity on the grandmother's child-rearing role are moderated by the relation with the grandchild. The direct effect of grandmother-adult child solidarity on grandmother's child-rearing role was therefore shown to be significant on the maternal grandmother. Fourth, the indirect effect of grandmother-adult child solidarity on the grandmother's child-rearing role through caregiving satisfaction was shown to be significant on the paternal grandmother. Based on the results of this study, we discussed ways to strengthen the capacity of co-parenting between grandparents and adult children.

This study examined the moderating role of teacher-child relationship on the relation between children's shyness and peer victimization. Participants were 200 children(97 boys, 103 girls; recruited from classes with 5-6 year olds) and their kindergarten teachers. The teachers completed rating scales to measure the children's peer victimization, shyness and teacher-child relationship. The collected data were analyzed using descriptive statistics, t-tests, correlations, and hierarchical multiple regressions. Boys and girls were analyzed separately. Results showed that children's shyness had a positive relation to their peer victimization. Teacher-child relationship significantly related to children's peer victimization. Hierarchical regression analysis indicated that the interaction of boys' shyness and teacher-child closeness predicted boys' peer victimization. Boys' shyness, whose teachers demonstrated the lowest level of teacher-child closeness, was significantly associated with their peer victimization. Boys' shyness had a significant relation to their peer victimization, especially for the highest level of teacher-child conflictual relationship. Results are discussed in terms of the role of teachers to shy boys' peer victimization.

This study investigated the relations among a child's emotionality, mother's depression and parenting behaviors in predicting a child's happiness. Participants were 384 children(175 boys, 209 girls) and their mothers. The teachers completed the rating scale to measure a child's happiness. A child's emotionality, mother's depression and parenting behaviors were assessed by a mother-reported questionnaire. The collected data was analyzed using descriptive statistics, correlations, and hierarchical multiple regressions. Results showed that child's emotionality was negatively related to their happiness. Mother's depression had a negative relation to child's happiness. Mother's warmth-encouragement, overprotection-permission, and reject-nonintervention was significantly related to a child's happiness. Hierarchical regression analysis indicated that the interaction of child's emotionality and mother's reject-nonintervention predicted child's happiness. Child's emotionality, whose mother demonstrated a higher level of reject-nonintervention, was associated significantly with happiness. In addition, the association between mother's depression and child's happiness was mediated by mother's warmth-encouragement and reject-nonintervention. Results suggest the importance of mother's role in the context of intervention planning for child's happiness.

Ontology defines the terms used in a specific domain and the relationships between them and represents them as hierarchical taxonomy. The present paper proposes a semi-automatic domain-specific ontology construction method based on terminology Processing. For this purpose, it presents an algorithm to extract terminology according to the noun/suffix pattern of terminology in domain texts and find their hierarchical structure. The experiment was carried out using pharmacy-related documents. As singleton terminology with noun/suffix were identified, the average accuracy was 92.57%. In case of multi-word terminology, the average accuracy was 66.64%. The constructed ontology forms natural semantic clusters with based on suffices and semantic information, so can be utilized in approaches to specific knowledge such as information look-up or as the base of inference to improve searching abilities.

In this study, we present an extended complex event model by considering both of the complex event and the aspect-oriented programming. We propose an advanced scheme for the event specification suited for the event correlation based network management systems by merging these two models. Specifically, we extend the model to support hierarchical event structures and let the model recognize point-cuts of aspect-oriented programming as events. We provide the event operators designed to specify the events on instances and handle temporal relations of the instances. Lastly, we compare the proposed model with other event models and present the benefits of it.

Owing to the increase in consumption of multimedia content and the improvement of device capacity, user demand for high-quality content has increased. However, it is difficult to transport such large amounts of content over the existing broadcasting network with limited bandwidth. To provide high-definition broadcasting, some studies suggest methods of transporting multimedia over heterogeneous networks after encoding content hierarchically. MPEG Media Transport (MMT), standardized by Moving Picture Experts Group (MPEG), is a solution that enables large-volume media transport over heterogeneous networks such as digital broadcasting networks and packet-switched networks. In the case of delivering a scalable encoded video over different networks, synchronization of each stream is an important issue. MMT defines a synchronization scheme, but does not contain sufficient functions to implement it. In this paper, we propose a synchronization scheme for media streams that are encoded hierarchically, divided into layers, and transported over heterogeneous networks. We implement our scheme using MMT and HTTP, and experimented using three encapsulated video streams with different durations. As a result, we show that the proposed scheme can reduce the waiting time to display high-quality video, relative to Dynamic Adaptive Streaming over HTTP-Scalable Video Coding (DASH-SVC) by requesting segments of enhanced layers after calculating the transmission time. Additionally, we find out that the selection of durations have a relation to the characteristics of the video.

One of the main problems in evaluating complex objects, such as an ill-defined system, is how to treat ambiguous aspect of the evaluation. Due to the Complexity and ambiguity of the objects, many types of evaluation attributes should be identified based on the rational dsision. One of these attributes is an analytical hierarchy process (AHP). the weight of evaluation attribtes in AHP however comes from the probability measure based on the additivity. Therefore, it is notapplicable to the objects which have the property of non-additivity. In the previous studies by other researchers they intriduced the Hierarchical Fuzzy Integral method or mergd AHP and fuzzy measure for the analysis of the overlaps among the evaluation objects. But, they need more anlyses in terms of transformation of the probability measure into fuzzy measure which fits for the additivity and overlapping coefficient which affects to the fuzzy measure. Considering these matters, this paper deals that, ⅰ) clarifying the relation between the fuzzy and probability measure adopted in AHP, ii) calculating directly the family of fuzzy measure from the overlapping coefficient and probability measure. A simple algorithm for the calculation of fuzzy measures and set family of those from the above results is also proposed. Finally, the effectiveness of the algorithm developed by applying this to the problems for estimation of safety in ship berthing and for evaluation of ports in competition is verified. This implied that the new algoritnm gives better description of the system evaluation.

Objective: The purpose of the present study was to examine the moderating role of childcare teachers' sense of humor in the relationship between their job stress and happiness Methods: Participants were 294 childcare teachers working at 83 childcare centers located in Busan and Gyeongnam. Teachers completed a rating scale in order to examine their demographic variables, job stress, sense of humor, and happiness. The collected data were analyzed using product-moment correlation and hierarchical multiple regression. Results: Childcare teachers' job stress was negatively correlated with their happiness. And childcare teachers' sense of humor had a positive relationship with their happiness. Hierarchical regression analysis indicated that the interaction of childcare teachers' job stress and sense of humor predicted their happiness. Childcare teachers' job stress was significantly associated with their happiness among those who demonstrated the lowest level of sense of humor. Childcare teachers' job stress had no relationship with their happiness, especially for those with the highest level of sense of humor Conclusion/Implications: We suggested that having a sense of humor might be valuable for childcare teachers in order to buffer the link between their job stress and happiness.
