Energy flow and C-$H_{methyl}$ and C-$H_{ring}$ bond dissociations in vibrationally excited toluene in the collision with $N_2$ and $O_2$ have been studied by use of classical trajectory procedures. The energy lost by the vibrationally excited toluene upon collision is not large and it increases slowly with increasing total vibrational energy content between 5,000 and 45,000 $cm^{-1}$. Intermolecular energy transfer occurs via both of V-T and V-V transfers. Both of V-T and V-V transfers increase as the total vibrational energy of toluene increases. When the total energy content $E_T$ of toluene is sufficiently high, either C-H bond can dissociate. The C-$H_{methyl}$ dissociation probability is higher than the C-$H_{ring}$ dissociation probability, and that in the collision with $N_2$ is larger than with $O_2$.

This study sought to analyze the trends in research on Korean fathers with young children. In this study, journal articles related to child and family studies, early childhood education and childcare published between 1980 and 2006 were analyzed for research frequency, content, and methodology. The study results were as follows. First, 56 research articles on Korean fathers with young children were published during this period of time. Second, the research was primarily focused on fathering attitudes and the relationships between the characteristics of the father and the development of the child. Third, the majority of the studies used methods categorized as quantitative and non-experimental: the subjects included more than 100 fathers with 3-5-year-old children. Research instruments validated in foreign countries (52.4%), surveys (75.4%), and quantitative data analysis methods (98.2%) were primarily used in these research studies. Finally, the results of this study suggest that further studies concerning Korean fathers with young children need to be conducted according to current research trends, content, and methodology.

Internet-based client/server architecture of Contents Delivery System suffers from frequent disconnections and security treats caused by dependency of the server or overload. But, We reached the limit to the increase of the server because a contents quality enhance and Internet user explosively increase. Therefore, a P2P based computing methods are used for sloving these issues. In this paper, We implement and design the Education Content Delivery System for cyber education system using idle Computing Power in P2P computing to share computing resources. We implement not only Internet infrastructure but also satellite infrastructure system, and designed to transfer real-time or non real-time contents.

For preservice teachers' instrumental-to-relational pedagogical content knowledge transformations, this research designed several didactical tasks based on Kinach's cognitive strategies. The researcher identified preservice teachers' understanding about what is a definition and how to teach it. By challenging their fixed ideas about definitions, the researcher could motivate them to embrace the new teaching approach which guides reinvention of definitions. The PCK development was not the simple process of filling their tabular rasa PCK with theories of mathematics education, but the dialectical process of identifying, challenging, changing and extending preservice teachers' existent PCK. This research will contribute to explore new directions of mathematics teachers' PCK development and the method of teacher education.

Purpose: This study was conducted to investigate the educational needs for practicing neonatal intensive care among Korean nursing students. Methods: An explorative, sequential, mixed-methods design was used. Qualitative content analysis was conducted of in-depth interviews of six nursing students, five clinical practice faculty members, and five nurses in the neonatal intensive care unit. The results of a survey of 174 nursing students were analyzed quantitatively. Results: Nursing students, clinical practice faculty members, and nurses wanted opportunities for direct nursing practice and education in school during neonatal intensive care practice. In terms of specific educational content, nursing students expressed the highest observation-related educational needs for communication with medical team members, and they expressed the highest practice-related educational needs for operating medical equipment used for neonatal intensive care. The nursing students' needs with regard to the method of practice education were highest for orientation from the head nurses. Conclusion: Communication and operating medical equipment were found to be areas with high educational needs for practicing neonatal intensive care among Korean nursing students. Further research is needed to develop an educational framework and setting for practicing neonatal intensive care that would meet their needs.

This study developed radiation therapy contents based on virtual reality technology and applied them to radiation students. A survey was conducted to analyze the relationship between learning effects and learning satisfaction to students who used virtual reality education videos to analyze their learning performance. 71 students radiology department were classified into two groups one that experienced virtual reality and the other that did not experienced virtual reality. We surveyed between the two groups analyzed self-directed learning, self-learning efficacy and learning satisfaction. As a result, the comparison between the two groups showed no difference between self-directed learning and self-learning efficacy. But the learning satisfaction was significant from 2.64±0.83 to 3.20±0.88 in the problem solving process for groups applying virtual reality contents. Therefore, learning satisfaction has improved experienced group virtual reality content and the materials for virtual reality education can be applied more efficiently in non-face-to-face lectures.

Liquid silicon rubber (LSR) has fine thermal compatibility and is widely used in various fields such as medical care and automobiles because it is easy to implement products with good fluidity. With the recent development of flexible sensors, the focus has been on manufacturing conductive elastomers, such as silicone as elastic materials, and carbon black, CNT, and graphene are mainly used as nanomaterials that impart conductive phases. In this study, mechanical behavior and curing behavior were measured and analyzed to manufacture a CB-LSR complex by adding Carbon Black to LSR and to identify properties. As a result of the compression test, the elastic modulus tended to increase as carbon black was added. When the swelling test and the compression set test were conducted, the swelling rate tended to decrease as the content of carbon black increased, and the compression set tended to increase. In addition, DSC measurements showed that the total amount of reaction heat increased slightly as the carbon black content increased. It is considered that carbon black was involved in the crosslinking of LSR to increase the crosslinking density and have a positive effect on oil resistance reinforcement.
