Researches on contact current and human body resistance by using precise human model at power frequency were carried out. In this study, the absolute values of internal body resistances were calculated for the two current paths. Its showed good agreement with another numerical data. But, they were twice or three times higher than the experimental ones. This implies that the factors such as the difference between in vivo and in vitro conductivities need to be considered. In addition, it was found that the internal resistances are widely influenced by current path which include extremities or not. And then, the current density of extremely high magnitude exceeding 100mA/m2 appears concentrically at heart and spinal cord in the torso as well as at extremities. These results indicate that concentration of internal current is influenced by cross-section area of current path and tissue's conductivity.

Tahitian dance is a traditional dance in Tahiti located in the Polynesian Islands. Bold and glamorous dancing using the body line unique to women attracts the hearts of the viewers. Costumes used for Tahitian dance are important things that influence the atmosphere of dance, and it was basic to handmade. Currently, although it is increasingly being marketed, the number isn't a lot and it is difficult to find a design that you like. In this study, we made a prototype which can design simple pareo design for the user can easily use. In this prototype, we prepare several types of Polynesian-like motifs to design in advance. The user can arbitrarily arrange, move and delete the motif selected here on the costume type, and design the entire pareo. In this paper, we post a pareo and a coconut bra & skirt design as an example of execution.

Archery is a popular sport among people with disabilities because rules of games are played according to relatively general archery competitions. However, the characteristic of archery is due to take aim at a target with one's eyes, it is currently difficult for visually impaired people to implement it. There are two important points for archers. Before shooting the arrow, which direction does the arrow aim at? After shooting the arrow, how many points did the arrow get? Therefore, in this paper, we propose a system that informs archer of the aiming directions and the detecting scores by voice using video sequences obtained from two cameras.
