A convolution neural networks (CNNs) has demonstrated outstanding performance compared to other algorithms in the field of face recognition. Regarding the over-fitting problem of CNN, researchers have proposed a residual network to ease the training for recognition accuracy improvement. In this study, a novel face recognition model based on game theory for call-over in the classroom was proposed. In the proposed scheme, an image with multiple faces was used as input, and the residual network identified each face with a confidence score to form a list of student identities. Face tracking of the same identity or low confidence were determined to be the optimisation objective, with the game participants set formed from the student identity list. Game theory optimises the authentication strategy according to the confidence value and identity set to improve recognition accuracy. We observed that there exists an optimal mapping relation between face and identity to avoid multiple faces associated with one identity in the proposed scheme and that the proposed game-based scheme can reduce the error rate, as compared to the existing schemes with deeper neural network.

The objectives of this study were to find relationships between ego identity and clothing benefits, and to examine the influence of ego identity, clothing attributes evaluation, and demographic variables on clothing benefits. The subjects were 405 college students(male : 164, female : 241) in Seoul. Six factors of clothing benefit derived by factor analysis : fashion, comfort, social recognition, self-expression, recognized brand, and economy. Males with higher goal-directedness of ego identity had less interest in the benefits of social recognition and recognized brand. The higher the uniqueness of ego identity females had, the higher the social recognition and the lower the comfort. Social recognition of males was influenced by self-acceptance(-), style, and fastener(R²=17.7%). and recognized brand influenced by parents\` education, goal-directedness(-), and allowance(R²=27.5%). Fashion of females was influenced by style, allowance(-), and goal-directedness(-)(R²=18.7%), comfort unfluenced by uniqueness(-), size, and allowance(-)(R²=14.6%), and self-expression influenced by style, allowance, fastener, and interpersonal relation(R²=28.0%). The present findings mean that allowance and ego identity such as goal-directedness, self-acceptance, interpersonal relation were meaningful variables that affect clothing benefits.

고유얼굴 기반 얼굴 인식 방법과 같은 얼굴 형태 기반 얼굴 인식 방법에 사용되는 1차원 PCA는 고차원의 얼굴 형태 데이터 벡터들의 처리로 인하여 부정확한 얼굴 표현과 과도한 계산량을 초래할 수 있다. 이에 개선 방안의 하나로 2차원 PCA 기반 얼굴 인식 방법이 개발되었다. 그러나 단순한 2차원 PCA 적용으로 얻어진 얼굴 표현 모델에는 얼굴 공통 특성 성분과 개인 식별 특성 성분이 모두 포함된다. 얼굴 공통 특성 성분은 오히려 개인 식별 능력을 방해할 수가 있고 또한 인식 처리 시간의 증가를 초래한다. 본 논문에서는 2차원 PCA 적용으로 얻어진 얼굴 특성 공간에서 얼굴 공통 특성 영향이 분리된 얼굴 고유 식별 특성 부분공간 모델을 개발하고 개발된 모델에 기반한 새로운 강인한 얼굴 인식 방법을 제안한다. 제안한 얼굴 고유식별 특성 부분공간 모델 기반 얼굴 인식 방법은 얼굴 고유 식별 특성에만 주로 의존하기 때문에 기존 1차원 PCA 및 2차원 PCA 기반 얼굴 인식 방법보다 얼굴 인식 성능 및 인식 속도에 대해서 더 우수한 성능을 보인다. 이는 다양한 조명 조건하에 다양한 얼굴 자세를 갖는 얼굴 이미지들로 구성된 Yale A 및 IMM 얼굴 데이터베이스를 이용한 실험을 통해 확인하였다.

The purpose of this study was to classify types in sense of gender role identity and to figure out the difference among sociocultural attitude, benefits of clothing pursuit, and appearance management behaviors by sense of gender role identity types. Questionnaires were administered to 455 people in their twenties and thirties living in Daegu and Kyoungbuk area. Data were analyzed by using frequency, factor analysis, credibility, $X^2$-test, ANOVA, Duncan-test, and t-test. The findings are as follows. First, Men of androgyny group showed the highest rate of 38.5% followed by undifferentiation(22.9%), masculineness(21.0%), and feminineness(17.6%). Women of undifferentiation group showed the highest rate of 33.2% followed by feminineness (25.2%), androgyny(22.0%), and masculineness(19.6%). Second, factors of sociocultural attitude were internalization and recognition. Benefits of clothing pursuit consists of the factors such as consciousness of others, personality, and vogue pursuit. Factors of appearance management behaviors were dressing, skin management, plastic surgery management, weight management, health management, and hair management. Third, the result from the difference between sociocultural attitude and benefits of clothing pursuit by sense of gender role identity types, men of androgyny and feminineness showed highest in recognition while women of androgyny showed highest in internalization and recognition. The result of the difference in benefits of clothing pursuit by sense of gender role identity shows that both men and women of androgyny group have high tendency for being conscious of others, personality pursuit, and vogue pursuit while men of undifferentiation and masculineness have low interest in dressing in relationship with others. Fourth, the examination of the difference in appearance management behavior by sense of gender role identity types found men of androgyny group managed dressing, skin, weight, health and hair most while women dress and health most. Men of undifferentiation group managed dressing and weight least, while men of masculineness health, and men of feminineness hair least.

This study focused on difference of the nation's concept between Ko un's Baekdusan and Lee uk's Gohyangsaramdul, Pungungi. These works are epics restructure nation's history. A epic's story provides framework of recognition to social members. An individual and community accept their story and then stories construct pesonal identity and community's identity. So we can say a epic configurates national identity by story nation history and nation territory. The nation's concept is understood steadfast and very pure as like a blood relationship in Korea. This is aspects of Korean nationalism. But the Nation is modern, social and historical concept. That is different from ethnic identity. This way throws open the door to analyze nation identity. Ko un's Baekdusan narrates permanence and sacralization of the nation for emphasizing the unification of North Korea and South Korea. Baekdusan expresses the social desire of Korea in the 1980s. In comparison, Lee uk's Gohyangsaramdul representate ambivalent attitude. One is a position as a settler and the other is a new master of Yanbian Korean Autonomous Prefecture. So Gohyangsaramdul narrates and remembers their motherland Chosun. But Pungungi exclude recognition of Chosun as motherland. This work's narration focuses on association with struggle of classes and anti-Japanese Movement during the Japanese colonial period. Because these events are able to unity Korean and Chines. Three works deal with same history and same background, but those show defferent recognition about the Nation. Because each society has different social desire and expect different future. The present desire and future prospect construct nation identity.

얼굴 인식 시스템의 성능은 조명 변화로 인하여 발생하는 개인내 (intra-person) 차이가 개인간 (inter-person)의 차이보다 클 수 있기 때문에 조명 변화에 많은 영향을 받는다. 본 연구에서는 이러한 문제를 해결하기 위해서 대칭형 bilinear 모델을 이용하여 조명 요소와 신원 요소를 분리하는 방법을 제안한다. Bilinear 모델로 조명 요소와 신원 요소를 얻기 위한 translation 과정은 반복적 역행렬을 구하는 것이 요구되는데 입력 데이타에 따라 수렴하지 않는 경우가 발생할 수 있다. 이러한 문제를 완화하기 위해서 ridge regression 모델과 bilinear 모델을 결합한 ridge regressive bilinear 모델을 제안하였다. 제안된 모델은 조명 요소와 신원 요소의 분산을 적절히 줄여줌으로서 bilinear 모델에 안정성을 제공하며, 인식에 더 많은 고차원 요소 정보를 이용하게 함으로써 인식 성능을 높여 준다. 실험 결과에서 제안한 ridge regressive bilinear 모델이 bilinear 모델, 고유얼굴(eigenface) 방법, Quotient image 보다 좋은 인식 성능을 보여줌을 확인 할 수 있다.
