The purpose of image fusion is to combine the relevant information from a set of images into a single image, where the resultant fused image will be more informative and complete than any of the input images. Image fusion techniques can improve the quality and increase the application of these data important applications of the fusion of images include medical imaging, remote sensing, and robotics. In this paper, we suggest a new method to generate a fusion image using the close relation of image features obtained through maximum entropy threshold and mutual information. This method represents a good image registration in case of using a blurring image than other image fusion methods.

The purpose of this study was to analyze STEAM learning/teaching program that relates robots and to develop and redesign STEAM teaching/learning program with a robot for elementary and secondary schools. 'Learning with a robot' is considered as one of the best candidates for STEAM education. This article mainly concerns a robot that can be helpful to improve students' interests in learning science and mathematics in schools. As the results of the STEAM learning/teaching program analyzing, the program for elementary schools contained more contents of liberal arts and fine arts, and the program for secondary schools contained more contents of science, technology, and math. In the middle school program, context for learning, class activities of creative design and emotional touch, evaluation, and job and career information were evenly implemented. In the elementary and high school program, there were few information about robotics career. We extracted all robot utilizable subjects and units from school curriculums, and redesigned contents which can be applicable to regular classes for schools.

The goal of this study is to suggest evaluation tools to assess computational thinking(CT) skills in primary robot-based programs. In addition, the researcher has expanded its evaluation approaches to include interpersonal competencies from the socio-cultural perspectives, not just focusing on intrapersonal competencies. In order to pursue the research goal, one-semester robots programs for the fifth graders were designed, and evaluation tools including a learners' CT competencies survey and a learning process monitoring rubric were developed. The results of this study are meaningful because it has expanded the evaluation approaches to connect to the concepts of CT and to include interpersonal aspects from the socio-cultural perspectives.

Flexible tactile sensors, which are primarily used as grippers in robots, are mainly used to handle highly elastic or highly flexible objects. That is, flexible grippers are used when an object cannot be sufficiently controlled by applying a specific output force or taking a specific grabbing action. This is because a flexible tactile sensor needs to measure the pressure applied directly to held objects while deforming according to the shape of the object to be handled. CNT-based sensors used to be made from a highly flexible polymer to give flexibility and it is known that the sensors are greatly affected by the contact resistance of the terminal that connects the sensor to an electrical circuit; therefore, this paper clarifies the contact resistance of MWCNTs-based flexible tactile sensors and terminals. The effects of main and plating materials for terminals are investigated and the combinations of main and plating materials that exhibit contact resistance are measured in a typical industrial environment.

Rapid development of educational technology requires fundamental changes not only in the form of instruction and role of teachers in school education but also in the competency development of students. Specifically, the emergence of new technologies such as makerspace, virtual reality (VR), and robotics has made it more challenging for teachers and students in the 21st century. However, even with the argument for the changes, less has been discussed about how much in-service teachers are aware of and how they are preparing for such changes. Therefore, this study intends to explore what would be required to students and teachers, and for instructional changes with more technologies available through the lens of elementary school teachers. The study results suggest, similar to previous studies, in-service elementary teachers recognize that student competencies such as creativity, collaboration, communication, and problem-solving skills are important. They also perceived that teacher change in role and attitude, and for instructional method and classroom culture are crucial as catalysts of change. Unique and interesting finding from this study is about the importance of nurturing digital citizenship in technology-infused learning environment. The digital citizenship has been less highlighted in the past, but this study revealed it should be treated as a priority.

The uncanny valley is a hypothesis about robotics concerning the emotional response of humans to robots and other non-human entities. Although it stands today as one of the robots and synthetic characters, the uncanny valley was speculative and few studies have been performed to test the theory. In two experiments, a total of 183 participants were employed to explore this hypothesis. The results of experiment 1 indicate that the perceived human likeness of a robot is not a key factor causing uncanny valley. And the results of experiments 2 suggest that even if the appearance and motion of a robot become fully human, the emotional response of humans could not reach human-human empathy levels.
