This study analyses on the history of uniform convergence, and discusses its educational implications. First, this study inspects 'overflowing of the Euclidean methodology' which was suggested by Lakatos as a cause of tardy appearance of uniform convergence, and reinterprets that cause in the perspective of 'symbolization'. Second, this study looks into the emergence of uniform convergence of Seidel and Weierstrass in this viewpoint of symbolization. As a result, of analysis, we come to know that the definition of uniform convergence had been changed into the theory of 'domain and graph' from that of 'point and function value' by the location change of the quantifier. As these results, this study puts forward an educational suggestion from an angle of epistemological obstacle, concept definition and concept image.

결합된 시변 상미분 방정식의 해외 점근적 성질에 관한 연구이다. 리아프노프 직접 방법에 의하면 평등 안정성(uniform stability)만 얻어졌을 경우이지만, 추가적으로 상태 벡터 중 일부가 0으로 점근적 수렴함을 보이는데 있다. 얻어진 결과는 특히 불변원리(invariance principle)가 성립하지 않는 시변 시스템에 유용하다.

The study is to grope for the unified device of the women's welfare policy in the United Korea by considering and comparing with the women's welfare in South Korea and North Korea centering on the women's welfare law and system among the social security laws and systems in the present both countries. The both Koreas have enforced the different women's welfare policies according to the different ideologies and constitutions. But in the welfare policy women are in the secondary stage by means of the ideology of sexual devision. It, therefore, is clear that the position of the North Korean woman goes in advance of the South Korean woman in the law and system. However, they are similar to the North Korean women in the aspects of the application of law and system. That is, both of them are discriminated not only in home and labor participation, but also in social welfare. There are the patriarchal family system and sexual devision of labor under the discrimination against woman. As though the both sexes are equal in law, the welfare law and system are applicated unequally to woman because of the ideology of sexual devision and familism which family should take the primary responsibility of welfare. From this perspective the women's welfare policy of the United Korea is not just to unify both laws and systems related women's welfare, but to search for the convergence on the higher level of quality and to make the real gender-equal society. The study suggests as the women's welfare the spread of the application of social welfare system, and social security network constructed through the mother protection policy, women's poverty and social security on basis of the primary principles such as the gender equal right as civil right, benefits of social welfare as social right, escape from the patriarchal familism, strengthening of resposibility of state and the principle of women participation in process of social welfare management. The device of women's welfare means building the social welfare system based on the real gender equality, so the unification will be the important turning point for the gender-equal society to the South-North Korean women.

The purpose of this study was to develop the first social work values scale in Korea. Its development would be expected to increase empirical studies on social work values. Based upon the literature review of social work values, the examination of codes of ethics as well as existing scales, and the comments from professionals in this field, 62 preliminary items were developed. Preliminary items were evaluated with a total of 521 social workers who were working in various fields of social work in Seoul and surrounding areas. A series of exploratory factor analyses were conducted to find out the optimal structure of the scale. After deleting 29 items with low factor loadings or being cross-loaded, the scale is composed of three factors with each factor having 11 items. Confirmatory factor analysis confirmed the factor structure of the scale obtained by exploratory factor analysis. The first factor was named autonomy, the second factor was named equality, and third factor was named paternalistic intervention. Each component of the social work values scale is found to be reliable and valid.

The aim of this study is to explore the paradigm shifts in culture and system related to life in terms of AI and the present point of view in which creating human values together are important. An approach that focuses on how AI-related phenomena work in modern society forms the basis of this research. Therefore, to clarify the meaning of "AI phenomenon" converging it as a part of social culture, this study was intended to find out the value incorporated in the social system such as ethics and equality together with the literature review. Inferring the technical culture that are combined with the AI that the members of society can do together is as important as technical understanding in the functional aspect. Therefore, this study was intended to suggest new culture that the cultural imagination and the social system create harmonizing each other, that is, the possibility of "AI culture".
