정보화시대에 접어듦에 따라 많은 공공기관에서 고령층을 위한 정보화교육을 실시하고 있다. 대부분의 공공기관에서 정보화교육을 신청하기 위해 회원가입 또는 본인인증을 요구하고 있고 회원가입을 위해서는 본인인증이 본인인증을 위해서는 본인명의의 휴대폰 또는 아이핀이 필요하다. 하지만 휴대폰을 이용한 본인인증의 경우 본인명의의 휴대폰이 없을 경우 본인인증을 받을 수 없고 아이핀 발급의 경우 고령층 사용자가 발급하기에는 복잡한 것이 사실이다. 따라서 본 논문에서는 비회원 신청을 기반으로 신규 신청자와 재신청자를 구분하여 본인인증정보를 관리하는 시스템을 설계 및 구현하였다. 신규 신청자의 경우 휴대폰인증, 아이핀인증, 방문인증 중 인증방법을 선택할 수 있으며 추첨 시 선정자의 성명, 생년월일, 성별을 조합하여 인증코드를 생성하여 저장 후 재신청시 해당 인증코드를 확인하여 본인인증 없이 교육신청이 가능하도록 구현하였다.

The problem of classifying of age, gender, and race images still poses challenges. Despite deep and machine learning strides, convolutional neural networks (CNNs) remain pivotal in addressing these issues. This paper introduces a novel CNN-based approach for accurate and efficient age, gender, and race classification. Leveraging CNNs with residual blocks, our method enhances learning while minimizing computational complexity. The model effectively captures low-level and high-level features, yielding improved classification accuracy. Evaluation of the diverse 'fair face' dataset shows our model achieving 56.3%, 94.6%, and 58.4% accuracy for age, gender, and race, respectively.

Mathematical, verbal, and spatial abilities are known as three important indicators for the success in the STEM disciplines. In this study, Purdue Spatial Visualization Test-Rotation, College Entrance Scholastic Aptitude Test- Math and Verbal score of engineering freshmen students have been used to find the relationships among these areas. In addition, gender differences in spatial visualization, verbal achievement and mathematical achievement have been investigated, too. In this research, I found that gender difference was highest in spatial visualization ability, followed by verbal achievement and smallest in mathematical achievement. Substantial number of male students possess high level of spatial abilities, but only half of female students were at the same level where their male colleagues were. The correlation between spatial ability and mathematical ability was negligible, contrary to former researches on elementary and middle school students. But the correlation was stronger for female students than male students. The correlation between mathematical achievement and verbal achievement was negative. It reflects the fact that when one section of SAT score is low, score of other sections should be higher to get admitted to college. Gender difference in mathematics was smallest for high achieving spatial ability group. For low spatial ability group gender difference in mathematics achievement has been observed, too. To find the combined contribution of spatial and verbal abilities to mathematics achievement, students were divided into 4 ability groups. Mathematics achievement decreased in the order of (1) high spatial -low verbal group, (2) low spatial - low verbal group, (3) high spatial - high verbal group, (4) low spatial - high verbal group.

The purpose of this study was to find out early childhood teachers' personality and analysis on the status and awareness of character education for early childhood education by grouping according to level of personality. The results show that there was significantly difference career and age. While early childhood teachers sympathize importance and need of personality education, absence of methods for practice is obstacle. A high level personality group notices that respect for early children' life, humanity and virtue of relationship is importance virtue. Therefore they consider respecting people as aim of personality education and recognize that they need to teach right values through whole area as education contents. A low level personality group notices that performance of their duty and manners of early children is needed virtue. They consider manners education as aim and content of personality education also recognize guiding with connecting home teaching is desirable. Early childhood teachers recognize that ambiguity of personality education's aim and contents, a gap between reality and ideals and absence of teachers' personality is difficulty of personality education.

The nostalgia marketing is active in various industrial areas. The nostalgic theme is emerging as a new trend in the film industry. This thesis attempts to investigate empirically the effect of nostalgia, the expectation and the evaluation on the intention to watch a movie. Nostalgia is a sentimental yearning for a former place or time. Expectation is classified into the utilitarian and the hedonic one; the evaluation into the subjective and the objective one. This thesis analyzed the effects of these five factors on the intention to watch a movie. The result shows that the older group felt more nostalgic than the younger; women more than men. Regarding the age, 10-20s are affected by the hedonic expectation, the subjective evaluation, and nostalgia, and over 30s are affected in order of the hedonic expectation and nostalgia. In terms of sex, men are affected most in order of the hedonic expectation, nostalgia and the subjective evaluation. Women are affected most in order of the hedonic expectation and the subjective evaluation. These results indicate that the marketing strategy needs to vary according to age and sex.
