Method: Semi-structured interviews on whether to return were conducted with nine participants aged 60 - 80 years (eight males and one female) residing in areas where evacuation orders were canceled. The data obtained were analyzed qualitatively and inductively. Result: All participants were returning to their homes. Factors relevant to self-determination to return were represented by five categories: a desire to return 1) emerging from life-experience as a long-term evacuee, 2) retained after obtaining information about the original place of residence, 3) acquired from a long-term life as a refugee, 4) retained with the acceptance of the potential risks of returning, and finally 5) people’s apprehension over talking about the importance of the future of the younger generation. Discussion: These categories were based on the participants’ desire to return and they continued to maintain these thoughts by gathering information and preparing for their return after the long-term evacuation caused by the nuclear accident. It was suggested that the risk perception and the norm in that age group could be among the factors that promoted the choice in maintaining the desire to return.展开更多

Fractal geometry is a methodology through which size reduction is achieved. A Self-similar fractal antenna using multicantor technique is proposed and experimentally studied. Space-filling cantors and self-similarity properties of fractal geometry have been adopted in the proposed antenna to miniaturize the size of antenna. The antenna is designed in such a way to operate at MICS band (Medical Implant communication Service) for wireless telemedicine application. The prototype antenna exhibits wideband characteristics and provides a good agreement of return loss (S11). Experimental return loss has been compared with that which is obtained using method of moments. The objective of using self-similar concept in antenna makes it flexible in terms of controlling the resonance and bandwidth. In this paper, the Self-similar property of fractal geometry is examined by maintaining return loss (S11) more than –30 dB approximately in all the iterations (n) and the prototype antenna has return loss greater than –10 dB and exhibits wideband characteristics.展开更多
