It is widely used that a network termination rate is calculated by using a Long Run Incremental Costing model. Interconnection Order issued Ministry of Information and Communication in Korea on December 2002 has declared that termination charges of local, national, payphone, and mobile calls are going to be determined by LRIC costingmodels after 2004. There are lots of preceding researches on a fixed network costing model for applying to LRIC method but on a mobile network not pretty much of them. Besides, Most important basis of current calculation models for termination charges are access costs to connect subscribers to network such as a local loop. In this paper, we look into being of access costs in mobile network and show the applicable standards for cost allocation of access costs in implementing LRIC costing model.

조은진,송연호,이영주,배현종 한국공업화학회 2016 Journal of Industrial and Engineering Chemistry Vol.40 No.-

This paper describes the preparation and characterization of a green magnetic nanocatalyst (GMN) thatis functionalized with carboxyl and imidazole groups, which hydrolyze b-1,4-glycosidic bonds with ahigh catalytic efficiency. The GMN mimics the structure of the active sites of polysaccharide-degradingenzymes under mild conditions (pH 5). The maximal glucose yield of 0.53 mg/mL and xylose yield of0.17 mg/mL were obtained from the enzyme cocktail of GMN and cellulase. The GMN also retained asignificant amount of activity after five consecutive reaction cycles.

1920년대 관립전문학교 대학 승격 운동의 추이와 성격: 경성법학전문학교와 경성의학전문학교를 중심으로

This study aims to explore the various aspects of the movement for promoting Government specialized schools to universities, which cannot be explained solely by the framework of existing student movements, through the case of the university promoting movement initiated by the students of Government specialized schools in the 1920s. The collective actions of the students of Government specialized schools in the 1920s were a prominent movement in Korean society. In particular, the movement initiated by students in Government specialized schools was extensively covered in the press, including Dong-a Ilbo and Chosun Ilbo. The internal movements in Government specialized Schools at that time can be divided into five categories: ① National issues, ② Promoting issues, ③ Equipment issues, ④ Faculty issues, and ⑤ Treatment issues. This study focuses on the movements related to promotion, especially the movement for university promotion centered on the Keijō Law and Medical Government specialized schools, which overlapped with the establishment of universities in Korea in the mid-1920s. In 1918, the Japanese University Ordinance, a law that became the basis for establishing universities, was promulgated in Japan. When the content of this law was conveyed to the Korean press, expectations for university promoting began to emerge in Keijō Law and Medical Government specialized schools. In particular, after the March 1st Movement, the colonial government was also planning to establish universities in Korea for smooth colonial rule. As news of the promoting of specialized schools to universities spread through the press in Japan, expectations for promoting state-run professional schools to universities in Korea also emerged. In particular Keijō Law and Medical Government specialized Schools, which were responsible for the newly established law and medical departments, began to actively engage in the movement for university promotion. In Keijō Law and Medical Government specialized schools, stuents became the center of the university promoting movement and began to show movement from 1923. However, the colonial government authorities stated that professional schools would be preserved and dismissed the demands for promoting the two schools. In Keijō Medical specialized school, the movement for upgrading became more active, as it was expected that human and material resources would be transferred to the university. In particular, Keijō Medical Government specialized school, which would face the situation of transferring facilities and professors to Imperial University when it was finally decided to establish it, showed a strong will for the promotion. However, in reality, the promotion of the two schools gradually became more distant, and the discussion on establishing universities in Chosun concluded with the establishment of Keijō Imperial University alone, as the government did not intend to allow multiple universities in the colonial era. In addition to the issue of the survival of two schools that overlap in department and content with Keijō Imperial University, the campus movements of the two schools thereafter were nothing but struggles for the survival of the students. Especially, Keijō Law Government specialized school reacted most sensitively to the problem of finding a new teacher, while Keijō Medical Government specialized school reacted most sensitively to the issue of local relocation. However, at that time, the students thought of the colonial government as a target for demand and negotiation, but not as a target for resistance. On the other hand, the colonial government reacted as if it was trying to reflect some of the students’ demands, but it was just a gesture to appease the students of Government specialized schools who had failed in their university promotion movements. .

층상자가조립법을 이용한 SiO₂나노입자증착 및 Silane물질코팅을 통한 초소수성 표면 구현

조은진,심봉섭 한국공업화학회 2016 한국공업화학회 연구논문 초록집 Vol.2016 No.1

물에 대한 친화도가 낮아 표면에서 물의 접촉각이 150° 이상인 경우 초소수성이라 한다. 초소수성이 있는 물질의 표면에서는 자가정화효과 (Self cleaning effect)가 나타나게 되는데, 이로 인해 초소수성은 산업분야에 다양하게 응용되고 있다. 이번 연구에서는 층상자가조립법(Layer-by-Layer assembly, LBL)을 이용해 유리 기판에 SiO₂를 10-20nm, 40-50nm, 80-90nm 크기 별로 코팅하여 나노구조를 형성시키고, Methyltrichlorosilane (MTCS)를 이용하여 소수성 표면을 구현하였다. SiO₂를 LBL한 시료를 SEM 촬영한 결과, 입자들이 유리표면에 증착되어 나노구조를 형성한 것을 확인할 수 있었다. 또한 접촉각 측정을 통하여 SiO₂를 코팅한 유리 기판이 코팅하기 전에 비해 훨씬 낮은 접촉각을 가지는 것을 확인하였다. 해당 시료에 MTCS로 코팅한 한 후에는 접촉각이 140° 이상으로 초소수성에 가까운 표면이 형성되었음을 확인하였다. 또한 초소수성 필름을 배 모형에 코팅한 결과, 항력효과에 의해 같은 힘으로 훨씬 빠른 속도로 움직이는 것을 확인할 수 있었다.

공감 중심의 유아 인성교육에 대한 고찰

조은진 서울여자대학교 사회과학연구소 2012 사회과학논총 Vol.19 No.-

학교 폭력을 비롯한 비인간화 현상의 심각성으로 인해 인성교육의 강화에 대한 요구가 커지고 있다. 공감은 다른 사람의 감정 상태를 수용하여 대리체험하는 것으로서 이타주의에 가장 근접하는 개념이며, 바람직한 사회적 관계를 지향하는 인성교육의 필수 요건으로 인식된다. 본 연구에서는 인성 형성의 결정적 시기라 할 수 있는 유아기부터 공감 중심의 인성교육을 확립하기 위한 기초로서, 관련 문헌과 선행연구의 고찰 및 분석을 바탕으로 공감의 의미와 형성, 발달적 특성, 교육적 함의 등을 탐구하였다. 유아 교실에서 공감능력을 기른 아이들이 사회적 관계를 향상시키고 공감과 배려가 풍성한 선진 문화사회의 성숙한 시민이 될 수 있다는 점에서 공감의 인성교육적 함의는 크다고 하겠다. Recently empathy has received considerable attention because of the impact such capacity has on children's interpersonal relations and the quality of human life. The capacity for empathy is generally considered an important mediator of prosocial behavior by philosophers and psychologists. The assumption is that people who vicariously experience another's distress, sadness, or other such reactions are motivated to alleviate the other's need. However, empathy is viewed a provocative construct, evoking argument over its concept and measurement. This paper is a review of research on the development of empathy in young children. The issues related to the development of empathy were discussed with respect to its implications for the educational settings. Focused on empathy, contents and methods of character education were reviewed critically. For parents and teachers of young children, teaching strategies that foster children's empathic abilities were also suggested. Key Words:Empathy, Character education, Young children.

유아의 상징놀이와 사회인지 발달: 통합적 고찰

조은진 서원대학교 교육연구소 1995 敎育發展 Vol.1995 No.14

This study is an integrative review of research on children's symbolic play development and its outcomes. The present study examines a developmental progression in the ability to engage in pretend play that seems to reach a crescendo during the preschool years. Recognition of make-believe as a central factor in play is reflected in a series of training studies n which adults have attempted to foster pretense in childern's play. The majority of training studies have investigated the transfer effects of training in pretend play to a variety of related social-cognitive skills, and mostly reported positive findings. These results provide credible evidence to support the theories of cognitive-structural-symbolic aspects of development(e.g., Piaget, Vygotsky), and underscore the educational value of training for the development of play ability. Results of these studies are reviewed and critiqued in terms of methodological issues. Then, areas in need of further inquiry are discussed with respect to issues that require empirical clarification

유아의 도덕성 발달과 도덕교육 연구

조은진 서원대학교 교육연구소 1994 敎育發展 Vol.13 No.1

Since theory or moral development has not yet settled down into an accepted system in many early childhood programs, this study was presented to review theories of moral development, to compare educational approaches to moral development, and to combine the most useful suggestions into an educational setting. From the theoretical ideas of Piaget and Kohlberg and some other research findings, it is indicated that the process of moral development is not imprinting rules and virtues, but rather the process of transforming mental sttuctures, a process that is contingent on cognitive growth combined with stimulation from the social environment. Influences on the Kohlberg stages include cognitive conflict, peer relation, and perspective taking. Criticisms include an overemphasis on cognition and an underemphasis on behavior, the quality of the research, an inadequate consideration of the care perspective, and an underestimation of the role of culture. As three educational approaches to moral development, character eduction, values clarification, and the cognitive-develomental approach were examind. Cognitive morl education was considered to help children understand and value the resoning behind the moral choices. With this approach, moral education means facilitating children's propgess through the stages of moral reasoning, leading to the adoption of freely chose moral values. Damon's view is more comprehensive than the traditional cognitive moral education viesws, because it recognizes the importance of emotions, parent-child relations, and culture in moral development, integrating them with the influence of schools, peers, and cognition in a meaningful way. Implications for future research and educational parctices were suggested, pursuing the development of a conscience and of a consistent set of moral behaviors.
