The open set recognition method should be used for the cases that the classes of test data are not known completely in the training phase. So it is required to include two processes of classification and the validation test. This kind of research is very necessary for commercialization of face recognition modules, but few domestic researches results about it have been published. In this paper, we propose an open set face recognition method that includes two sequential validation phases. In the first phase, with dummy classes we perform classification based on sparse representation. Here, when the test data is classified into a dummy class, we conclude that the data is invalid. If the data is classified into one of the regular training classes, for second validation test we extract four features and apply them for the proposed decision function. In experiments, we proposed a simulation method for open set recognition and showed that the proposed validation test outperform SCI of the well-known validation method

The formation of knowledge of the people of Korean society is the social practices of collective subjectivity. Subjectivity is the truth of the self, which is incessantly created, questioned and modified in the milieu of self-reflection. In an attempt to examine the hermeneutics of the subject of Korean society, a conceptual framework is proposed, which, with the notion of life embedded, consists of a historical sequence of the popular, minjung, multitude, people and community. The period of 1960s saw the ambiguous mass of lifes floating, the individual with his/her own interior world of consciousness emerge. The ideological solidarity is formed in the the next two decades, in contestation with immediate and physical threatening such as poverty and dictatorship. The democratization of Korean society and the global expansion of neoliberal regime gave a re-birth of multitude and people which is characterized with their pursuit of the co-existence and co-realization of singularity and universality on the ethical principle of the open and communicative radicality.
