This study investigated the difference of perception and needs among director, teacher, and parent for an open-childcare center focused on parent participation. The subjects of this study consisted of 56 directors, 231 teachers, and 299 parents in childcare centers in Seoul, Gyeonggi, Incheon, Chungcheong, and Gyeongsang province. They completed a questionnaire about the perception and needs of an open-childcare center, which was later analyzed by SPSS ver. 23.0. The findings were as follows. First, five areas of open-childcare center were 'participating activities as various roles,' 'willingness of parent participation,' 'reflection of parent needs,' 'concern about CCTV,' and 'sharing outdoor spaces.' Second, the perception of directors concerning open-childcare centers were higher than the ones for teachers or parents; however, there were differences in perception depending on their perspective position. The biggest perception of directors was 'participating activities as various roles,' and parents' one was 'concerned about CCTV.' However, the perceptions of teachers were a lower level than the other two groups'. Third, the directors showed a higher level of needs to promote an open-childcare center (except for one concerned about CCTV). Parents also showed their needs 'increasing awareness of open-childcare program,' 'promoting to parent's participation,' 'communication with on-line,' and 'concerning CCTV.' The implication of these results were discussed as action plans to promote an open-childcare center.

Mobile device users are sensitive to pay telecommunication charge for downloading Internet data, because the cost is proportional to the amount of data received. If there are device users who want to download the same content, they may cooperate each other to form an ad hoc network and share the partially downloaded content in order to reduce the amount of data downloaded. Each mobile device, called a peer, downloads a specific portion of the whole content using fee-based telecommunication channel, and exchanges the portion with other peers with free ad hoc channel in order that all participating peers are able to reconstruct the whole content in this situation, al1 participating peers become senders and receivers at the same time. In order to distribute the partial content to other peers, the ad hoc network requires a control led distribution mechanism. This paper introduces the per-peer-based distribution method in which one designated peer can transmit partial data to its neighbors at a time. Simulation results show that 90$\%$ of the telecommunication cost is saved with as few as 10 peers .

The purpose of this study is to analyze the performance of ABEEK accredited engineering program in D University. Based on engineering students' perceptions, this study explores how well the students are aware of the accredited engineering program, what change has been made to the courses, to what extent they have been participating in class and interacting with teachers and other students, to what extent they have been actively participating in extra-curricular activities, and to what extent they have achieved program outcomes. The survey was conducted in Fall 2014. The results are as follows: First, the students are well aware of the accredited engineering program; however, they are rarely aware of program outcomes. Second, the students were more satisfied with the major and design courses compared to the MSC and general education courses. Third, the students were more actively participated in the major and design courses compared to the MSC and general education courses. Fourth, the students were passively engaged in extra-curricular activities. Finally, the program outcomes related to soft skills showed low-achievement.

The purpose of this study is to infer how is the effect of a governmental funding project to graduate schools by taking an example of World Class University Project's potential impact on the change of world university rankings in an international university ranking survey. Systematic results show that WCU contributes to improving academic peer reviews for both individual and institutional standings and discipline-based rankings. The potential effect of improving world rankings of participating universities could be ascribed to relatively higher weight of the survey to international peer review and invitation of world class scholars to the participating universities, which is a core device of the project. This implies a need to affirmatively utilize WCU foreign scholars over the course of facilitating international academic networking. The results should also be taken into consideration by universities and the government when developing evaluation systems and restructuring the project.

It was only 2010 when start-up education spread to undergraduate education in South Korea. Start-up education was conducted so late that there are insufficient studies of evaluation and feedback on the effectiveness of start-up education. Education is a complex concept of teaching people in a desirable direction and developing their inherent abilities. Based on this, start-up education can be defined as cultivating students' entrepreneurial spirit internally and making them exhibit start-up competence externally by teaching them the knowledge, skills and attitudes necessary for business start-up and developing abilities such as creativity, challenge spirit and problem-solving skills. This study conducted pre and post survey to check if the education camp for the technology start-up, which is a practice-oriented start-up education, has an effect on the change of the participating students' perceptions about the business start-up. This study would analyze various factors of college students' business start-up through a factorial analysis so that the quantitative accumulation of start-up education can lead to a qualitative change and propose measures for the management of the quality of the education.

This study investigates the flow that customers experience when they participate in a design process for the mass customization of apparel products according to participation level and individual personalities. In addition, how the flow influences the satisfaction and final purchase intention is also examined. The subjects were 600 female consumers. The following results were found: First, the level of mass customization was higher, the enjoyment, concentration, product satisfaction, and total satisfaction were higher. Second, the paths of 'participating ability'$\rightarrow$'flow', 'flow'$\rightarrow$'satisfaction'$\rightarrow$'satisfaction' 'final purchase intention' were significant. The process satisfaction had a more significant influence on the final purchase intention than the product satisfaction. Finally, the participation ability had a moderating effect for the flow experience according to the level of mass customization.

IoT can be connected through a single network not only objects which can be connected to existing internet but also objects which has communication capability. This IoT environment will be a huge change to the existing communication paradigm. However, the big security problem must be solved in order to develop further IoT. Security mechanisms reflecting these characteristics should be applied because devices participating in the IoT have low processing ability and low power. In addition, devices which perform abnormal behaviors between objects should be also detected. Therefore, in this paper, we proposed D-IDS technique for efficient detection of malicious attack nodes between devices participating in the IoT. The proposed technique performs the central detection and distribution detection to improve the performance of attack detection. The central detection monitors the entire network traffic at the boundary router using SVM technique and detects abnormal behavior. And the distribution detection combines RSSI value and reliability of node and detects Sybil attack node. The performance of attack detection against malicious nodes is improved through the attack detection process. The superiority of the proposed technique can be verified by experiments.

Background Interest in global health and international mission trips among medical student and resident trainees is growing rapidly. How these electives and international mission experiences affect future practice is still being elucidated. No study has identified if participation in international surgical missions during residency is a predictor of participation in international surgical missions in practice after training completion. Methods All trainees of our plastic surgery residency program from 1990 to 2011, during the implementation of optional annual international surgical missions, were surveyed to determine if the graduate had gone on a mission as a resident and as a plastic surgeon. Data were compared between graduates who participated in missions as residents and graduates who did not, from 1990 to 2011 and 1990 to 2007. Results Of Plastic Surgery graduates from 1990 to 2011 who participated in international missions as residents, 60% participated in missions when in practice, versus 5.9% of graduates participating in missions in practice but not residency (P<0.0001). When excluding last 5 years, graduates participating in international missions in practice after doing so as residents increases to 85.7%, versus 7.41% who participate in practice but not residency P<0.002. Conclusions Results reveal plastic surgeons who participate in international surgical missions as residents participate in international surgical missions in practice at higher rates than graduates who did not participate in missions during residency. International missions have significant intrinsic value both to trainee and international communities served, and this opportunity should be readily and easily accessible to all plastic surgery residents nationwide.

The purpose of this study was to analyze the Jeju beach science camp program and to survey the participating students'' preference levels for the activities included therein. The camp programs were analyzed on the basis of the standards set for the HASA curriculum. The program's "manipulatory skill" area included many manipulatory and creative activities while the "inquiry area" included many basic and integrated inquiry activities. It was also indicated that the "knowledge area" included many activities appropriate for understanding concepts and principles while the "attitude area" included many activities appropriate for stimulating curiosity and enjoyment. Thus, it could be seen that the areas stipulated for the HASA curriculum were considerably consistent with the purpose of the science camp. The participating students showed preference for manipulatory and creative activities included in the program. They also preferred basic, inquiry level activities included under the area of "inquiry skills." It was identified that the students most preferred the conceptual stage included under the area of "knowledge" where they were required to grasp the common characteristics of events, things, and phenomena, as also the enjoyment stage included under the "attitude" area, where they were required to participate in pleasant science activities. These findings indicate that science camp programs should be composed of manipulatory and creative activities as well as activities that aim at basic research and the understanding of concepts.
