This study concerns the understanding of 'social exclusion' which is getting poplular in Europe as the new term or paradigm in order to resolve poverty problem. As case study on the France, the purpose of this study is to extract the consideration of welfare policy and suggestions as to us. In order to understand comprehensively the concept 'social exclusion' and the situation of the France, this study analyzes the existing researches on its concept and tries to realize a comparative study. Thus, this study indicates that the France is the state which has taken the most interest in 'social exclusion'. The second parti of this study concerns the change of the concept 'social exclusion' and its policies in the France. The concept 'social exclusion' which has used in the 1960's, has settled as the term of policies in the 1980's, thanks to seriousness of poverty and unemployment problem and change of social consciousness (opinion). As policy on the 'social exclusion', there are Revenu minimum d'insertion of the 1988 and law on the social exclusion of the 1998. Through analysis of policies on the 'social exclusion' in the France, we can get the following consideration of welfare policy and suggestions: on the macro level, the necessity to establish the comprehensive perspective on the poverty problem, invention and development of the term as regard to social new problem; on the micro lever, planning of welfare program according to clients needs, importance of perpetual assessing of the existing welfare program and institutions, the institutional establishment of 'reserve budget', the application of decentralization principle and the active participation of the private sector in order to promote the effectiveness and the efficiency of the program and institutions.

Leaked Radioactive source in nuclear power station, radiation related facilities and the aging nuclear power plant for the dismantling must need to detect and remove early to prevent major accidents. In this paper, we implemented a single sensor-based gamma-ray detectors stereo which can provide the distance to the radiation source, a direction and doserate information for fast and efficient decontamination work the radiation source. And we have carried out an algorithm development for high-speed detection of the detection equipment. Two detectors are required for stereo structure for obtaining the distance information of the radioactive source, but we designed the only sensor-based detection device for the weight reduction. We have extracted the region of interest and obtained the distance calculation result and distribution of radiation source in order to minimize a stereo image acquisition time. Detection time of the algorithm showed a shorter time of about 41%.
