The general bus architecture consists of masters, slaves, arbiter, decoder and so on in shared bus. Specially, as several masters do not concurrently receive the right of bus usage, the arbiter plays an important role in arbitrating between shared bus and masters. Fixed priority, round-robin, TDMA and Lottery methods are developed in general arbitration policies, which lead the efficiency of bus usage in shared bus. On the other hand, the bus architecture can be modified to maximize the system performance. In the paper, we propose the flying master bus architecture that supports the parallel bus communication and analyze its merits and demerits following various arbitration policies that are mentioned above, compared with normal shared bus. From the results of performance verification using TLM(Transaction Level Model), we find that more than 40% of the data communication performance improves, regardless of arbitration policies. As the flying master bus architecture advances its studies and applies various SoCs, it becomes the leading candidate of the high performance bus architecture.

The purpose of this study was to investigate and compare how the Enneargram personality types of teachers in early childhood education and care would affect their job satisfaction and stress coping strategies. The findings are as follows. First, as to the distribution of the participants' Enneargram personality types, the most common was the Peacemaker type and the least common was the Achiever type. Second, for teachers' job satisfaction, there was a statistically significant difference in the job-related subcategory according to their personality types. The post-hot comparison showed that the Loyalist type showed the lowest score in job-related job satisfaction. Third, in terms of stress coping strategies, there was a statistically significant difference in the psychological coping strategy according to their personality types. The post-hot comparison showed that the Individualist type showed the highest score in psychological coping strategy. The implications for future studies are also discussed.

As a means to support maternal transition, a home-based music intervention was employed to facilitate mothers' singing to their infants. Four mothers were recruited as volunteers for this study their typically developing infants ranged in age from 2 months to 11 months. Interviews were conducted after the completion of the intervention. An educational music intervention was used to introduce the benefits of mothers' singing to their infants and to encourage four mothers to perform regular singing to their infants for the two-week period. In the interview, mothers provided valuable information regarding their personal experiences, thoughts, abilities to carry out the daily singing, and additional support needs in singing. All mothers demonstrated positive experiences and needs for future intervention development. Overall, the results showed that music-involved educational intervention is beneficial for mothers to support their maternal transition. The need emerged for future studies to develop music-involved educational intervention to support maternal transition.

This study aims to look for care quality factors reduce the daily stress of young children placed in care centers for long hours. Therefore, the research questions look into how the hours and care quality factors in child care centers affect young children's daily stress, and whether the care quality factor moderates the impact of the hours children spent in centers. The subjects in this study were 380 children from 3 to 5 years old from 10 child care centers. The Korean Preschool Daily Stress Scale(KPDSS) for children's daily stress and Early Childhood Environmental Rating Scale-Revised(ECERS-R) for quality of each classroom of centers were implemented. The main findings were summarized as following: (1) The more hours he/she spent in the center, the more stress he/she had. Children who spent 9 hours or more had more stress than children with 7 hours or less. (2) Among the 7 quality factors including space and furnishings, personal care routines, language reasoning, activities, interaction, program structure, parents staff, the interaction level between a teacher and a child and the level of parents and staff had the most impact on children's daily stress. (3) The qualitative factors of child care, language reasoning level, interaction level, parental support, and level of teachers reduced children's daily stress which was affected by the hours they spent in centers. Thus in order to reduce the daily stress of children who attend more than 9 hours a day, it is crucial to promote language reasoning activities and interaction between teachers and children and to improve parental support and teachers' professionalism.
