Nowcasting algorithms using weather radar data are mostly based on extrapolating the radar echoes. We estimate the echo motion vectors that are used to extrapolate the echo properly. Therefore, understanding the general characteristics of these motion vectors is important to improve the performance of nowcasting. General characteristics of radar-based motions are analyzed for warm season precipitation over Jeju region. Three-year summer season data (June~August, 2011~2013) from two radars (GSN, SSP) in Jeju are used to obtain echo motion vectors that are retrieved by Variational Echo Tracking (VET) method which is widely used in nowcasting. The highest frequency occurs in precipitation motion toward east-northeast with the speed of $15{\sim}16m\;s^{-1}$ during the warm season. Precipitation system moves faster and eastward in June-July while it moves slower and northeastward in August. The maximum frequency of speed appears in $10{\sim}20m\;s^{-1}$ and $5{\sim}10m\;s^{-1}$ in June~July and August respectively while average speed is about $14{\sim}15m\;s^{-1}$ in June~July and $8m\;s^{-1}$ in August. In addition, the direction of precipitation motion is highly variable in time in August. The speed of motion in Lee side of the island is smaller than that of the windward side.

Purpose: Most of the currently used concepts and measurements of social support have been relevant for general population. The main purpose of this study is to conduct the concept analysis of perceived social support(PSS) of family caregivers for people with dementia. Methods: This study adopted the Walker and Avant concept analysis methodology. Results: Findings from this concept analysis suggested four defining attributes of PSS of family caregivers for people with dementia: 1) PSS is help or assistance that family caregivers perceive as available when needed; 2) PSS is offered through socio-ecological structure; 3) PSS has a specific function to meet the needs of family caregivers; and 4) PSS includes quality aspects where family caregivers choose, use, or evaluate it. Borrowing from the socio-ecological model, this study proposed the structural aspects of PSS. This study also identified functional aspects of PSS, such as emotional support, informational support, appraisal support, and practical support. Finally, this study assessed quality aspects of PSS, such as satisfaction, timeliness, usefulness, accessibility, and coordination. Conclusion: Focusing on family caregivers for people with dementia, we proposed a new model of PSS. The present study helped refine and clarify the concept of PSS of family caregivers for people with dementia. The results of this study may also contribute to promoting the development of more effective instruments for the concept.

As the age in which the importance of sensitivity has increased, education for the future generation regarding emotion engineering, affective recognition and cognitive science have taken center stage. We measure human's emotion quantitatively, analyze evaluation and apply them to various services in life, which are based on human technology. Therefore, we need the education which is related to emotion science to cultivate talented people. The goal of this paper is to suggest the possibility of emotion science education and effective methods through development of the STEAM (Science, Technology, Engineering, Arts, Mathematics) program which can teach emotion science to early elementary school students by applying it to pilot classes. For this study, first, we build a program, 'The mind made by figure' for student of early elementary school. The method of STEAM was used in this program, because it is an effective system to educate the emotion science. We recognize the needs and value of this program development through theory and benchmarking of STEAM related to emotion science. And then the contents of class, activities, course book and kit are designed with elementary school textbook of pertinent grade. Secondly, we analyze the result which is applied in two pilot classes of second grade by satisfaction survey and teacher interview. As a result, the average of satisfaction level was very high (4.40/5), Class participation was especially high. Third, we discuss the ability, value and limits of this program based on the result of analysis. The outcome of this research shows that students of early elementary school who have difficulty in understanding science can approach the education program related to emotion science with ease and interest. We hope this education will help students understand emotion science effectively, and to train people to lead the emotion centered era.
