The female leadership styles in the 21st century have been established as a major axis. Especially, the fashion of female politicians being exposed to the public during political activities has become a main element of a measure displaying visually female leadership styles in the 21st century and image making as well. Consequently, this study conducted qualitative research through the interview method to figure out regular voters' thoughts in depth about images being required for female political leaders and the fashion maximizing those images, and drew the detailed design elements. Suggesting the clothes design reflecting those elements for female political leaders by 3D virtual clothing works emerging as a new market creating profits related to fashion. The images which female political leaders have to have and were extracted through the interviews in this study, showed as feminine, strong leader, honest, and intelligent images, and also it was shown that female political leaders displaying proper images depending on the circumstances and using those images in politics rather than sticking to a fashion identity were favored by interviewees. The present study intends to contribute to being used as basic data of various research and fashion items of virtual reality and establishment of successful fashion strategy for female political leaders.

SRAM-based FPGAs are very sensitive to single event upset(SEU) induced by space irradiation. To mitigate SEU effects, space applications employ some mitigation schemes. The triple modular redundancy(TMR) is a well-known mitigation scheme. It uses one or three voters as well as three identical blocks performing the same work. The voters can mask out one error in the outputs from the three replicated blocks. One SEU error in TMRed circuits can be masked but it needs to be detected for some reasons such as to analyze the SEU effects in the satellite or to recover the circuits from the error before additional error occur. In this paper, we developed a fault detection circuit and reporting system to detect a fault on the TMRed circuits. To verify our error detection circuit and reporting circuit, we performed an irradiation test at MC-50 Cyclotron. Experimental results showed that error detection circuit can detect a fault on the TMRed test circuit in radiation environment.

Public opinion polls have a strong influence on modern society as a means of examining the tendency of social groups on specific issues. As the influence of the polls increases, the problem of forgery and falsification of the results becomes an important issue. So, to guarantee the reliability of the results, our society needs novel mechanisms. As one of such mechanisms, the Ethereum blockchain is an environment for developing decentralized applications with the reliable blockchain technology. Ethereum decentralized applications can utilize smart contracts to provide services for users in transparent and reliable ways. In this paper, we propose a polling method that guarantees reliability using the blockchain technology, which is a distributed ledger technique that makes forgery or falsification actually impossible. The proposed method provides a robust verification function on the results of the associated polls for individual voters and verification organizations. Also, we present a distributed opinion polling application running on our private Ethereum blockchain network, showing the effectiveness of the proposed method.
