The national curriculum includes the problem solving process, algorithms, and programming of SW education. The education using robots is one of attractive alternatives for students who have no interest of SW or are poor at programming. We have developed a courseware using robots for SW education based on paper art activities with narrative storytelling to enhance students' creative thinking and problem solving within limitation of class time in schools. We apply the courseware and obtained the result of pre and post-test on the creative problem solving ability of third graders in the elementary school The four factors of creative problem solving have shown significantly increase. In addition, it had an significant effects for understanding robot technology and for learning attitude using robots of SW or programming.

Researchers in the field of psychology used Electroencephalographic (EEG) to record activities of human brain lot many years. As technology develope, neural basis of functional areas of emotion processing is revealed gradually. So we measure fundamental areas of human brain that controls emotion of human by using EEG. Hands gestures such as shaking and head gesture such as nodding are often used as human body languages for communication with each other, and their recognition is important that it is a useful communication medium between human and computers. Research methods about gesture recognition are used of computer vision. Many researchers study emotion recognition method which uses one of physiological signals and gestures in the existing research. In this paper, we use together physiological signals and gestures for emotion recognition of human. And we select the driver emotion as a specific target. The experimental result shows that using of both physiological signals and gestures gets high recognition rates better than using physiological signals or gestures. Both physiological signals and gestures use Interactive Feature Selection(IFS) for the feature selection whose method is based on a reinforcement learning.

We are striving to strengthen environmental regulations and reduce household waste in all countries around the world. Korea is also striving for the circulation of energy resources by enacting laws to promote resource saving and recycling. The government has implemented an empty bottle deposit system for the recycling of empty bottles, but there is a limit to the collection through manpower and the reverse vending machine is not localized. In this paper, we propose a recyclable bottle recognition and classification algorithm which is essential in the reverser vending machine to promote energy resource circulation. The proposed algorithm is a complex identification algorithm using OpenCV and CNN(Convolution Neural Network). In order to evaluate the effectiveness of the proposed algorithm, we implement a classification system that operates in an reverse vending machine, so that it can easily acquire information about bottles and reverse vending machine in various devices.

As the Internet is widely used worldwide, digital asset on the internet becomes to be critical to protect from illegal copying and piracy which is an unlawful action that download or upload copyrighted materials from the Internet without having a right to use them from the copyright owners. Such an illegal and unethical behavior are pervading and becoming a big concern in many industries and business sectors over the world. This study examines the effect of the user's perception for piracy regulation and moral obligation on online piracy intention. Therefore, the purpose of this study is to see the different effect of regulation and moral obligation on piracy attitude and intention so as to suggest an effective method of piracy protection and to bring an attention on moral and ethical education for online piracy. The result of this study showed both punishment and moral obligation toward online piracy are significantly associated with users' attitude on piracy, indicating that higher level of punishment severity as well as moral obligation lead to decrease piracy attitude. This research also revealed that the level of users' moral obligation has a stronger relationship with piracy attitude than punishment.

Computer education currently executed at middle schools showed problems of system of education curriculum, repetition, and lack of consistent system as a result of analyzing index for information and communication technology curriculum, and related literatures, and most of the education contents have difficulty to nurture logic thinking and problem-solving ability since they are composed mainly of software function learning. Concerning this issue, this study suggests an innovated computer education curriculum with reinforced information ethics field with computer principle, algorithm, and programming, in other words, a corrected and supplemented version of former content system based on computer science guidance cases of ACM computer science curriculum model of USA, computer science curriculum of Florida state, and Unplugged Project(http://www.unplugged.canterbury.ac.nz) judging that introduction of computer science factors are desperate to improve computer education curriculum in middle schools.

This study explores what kinds of strategies are appropriate or needed for the academic librarians to upgrade their skills in the digital age. Printed and electronic sources related to this topic are gathered and examined, and communication with some academic librarians in USA is used for this study. The skills suggested in this paper mostly come from business-oriented concepts ike Learning Organization, Knowledge Management, Team Management, Customer-Oriented Services, and Change Management. As a result of this study, it is found that these skills can be used without much difficulties in academic libraries to improve their services. However academic librarians need to keep in mind the core values of academic libraries as an academic forum and non-profit organization when they endeavor to provide better services for customers in the digital age.

The purpose of this study seeks entry into a method to make the use of educational aids popular. To achieve it, it is observed that instructions applying worksheets to make an activation of use of educational aids have influences on mathematical achievement and mathematical disposition and attitude. All variables exception with the frequence of use of educational aids are controlled in both experimental group and comparative group. According to the result, there is no significant difference of mathematical achievement in pre t-test between two groups, while experimental group get 10 points higher than comparative group in average (t=0.519, p<0.01). On the other hand, within intra-experimental group the influences of use of educational aids on mathematical achievement is positive without the achievement levels of students. The difference dependent on the levels of student is sought by ANCOVA using prescores as a covariance, and it appears in the significance level of 5%(F=4.885, p<0.05), and the effect is more in the lower level of students than in the middle and high level.

The purpose of this study was to evaluate effects of mobile web-based cardiopulmonary resuscitation(CPR) convergence education for nurses. This study used a nonequivalent control group pretest-posttest design. A sample of 46 nurses was included. The experimental group was given mobile web-based online CPR education with self-directed offline CPR practice. The control group was given traditional CPR lecture education with CPR practice. The data were collected using a structured questionnaire and performance skill test and were analyzed using SPSS 21.0 program. The experimental group had higher scores on CPR knowledge and CPR self-efficacy than those of the control group. there were no significant differences between groups (p=.741; p=.162). CPR skill ability was significantly higher in the experimental group compared to the control group(p=.001). This findings indicate that mobile web-based CPR convergence education can be an effective to strengthen CPR capabilities for nurses. These contribute to expanding convergence of education program development.
