The content of emerging hero is a material of many roles in the development of video content. In recent years, the hero story taking advantage of the powered suit are appearing, and the popularity is also high. The powered suit was first advocated by Robert Anson Heinlein called science fiction writer, and he contributed to creation of diverse and numerous powered suit content. In particular, the powered suit content combined with epic heroes has become popular with many crush to audiences. In this study, what is the powered suit content and analyzed characteristics within the content of the powered suit by content analysis of utilizing the powered suit materials. It is thought that the powered suit content is gaining popularity to a large audience because it focused on realistic, scientific storyline than a traditional hero narrative.

Wearable robots are receiving great attention from the public, as well as researchers, because its motivation is to improve the quality of lives of people. Above all, complete paraplegic patients due to spinal cord injury (SCI) might be the most adequate target users of the wearable robots, because they definitely need physical assistance due to the complete loss of muscular strength and sensory functions. Furthermore, the medical care of complete paraplegics by using the wearable robots have significantly reduced the mortality rate and improved the life expectancy. The requirements of the wearable robot for complete paraplegics are actuation torque, locomotion speed, wearing sensation, robust gait stability, safety, and practicality (i.e., size, volume, weight, and energy efficiency). A WalkON Suit is the wearable robot that has satisfied the requirements of the wearable robot for complete paraplegics and participated in the powered exoskeleton race of Cybathlon 2016. In this paper, configuration of the WalkON Suit, human-machine interface, gait pattern, control algorithm, and evaluation results are introduced.

In this paper we propose a wearable elbow rehabilitation robot applied the mirror therapy for elbow rehabilitation. To implement the mirror therapy, a data suit for measuring healthy elbow motion is developed. A powered elbow exoskeleton wearing in paralyzed arm is controlled by the measured data from the healthy elbow motion. In experiments, the elbow rehabilitation exercise by the mirror therapy is performed. From the experimental results we show the wearable exercise robot including the data suit is applicable to the mirror therapy for elbow rehabilitation.

The development of efficient systems for water quality improvement for water sources such as lakes, dams and reservoirs has become a necessity to provide not only a cleaner and safer water to the urban society, but also to provide a cleaner and safer environment for the aquatic organisms living in lakes, dams and reservoirs. This study concentrates on the outlet design and internal flow analysis of an axial flow pump used in a floating type water treatment system completely powered by renewable energy source. The treatment system is designed to raise water from depths of about 3~5m up to the water surface where it is naturally mixed with air as it is released back to the reservoir. The outlet of a typical axial flow pump is modified to suit the floating type water mixer. The performance of the axial flow pump is studied by investigating the internal flow of the system. Results show that the change in outlet shape does not alter the performance of the original pump at the maximum efficiency point as long as the cross sectional area of inlet is the same as the outlet. The axial pump for floating type water treatment system has good cavitation performance in the whole flow passage.
