본 연구는 원형 터널에서 지반-라이닝 상호작용에 대한수학적 모델에 관한 연구를 다룬다. 정적, 동적 하중으로 인하여 터널 라이닝에서 발생하는 축력과 모멘트를 구하는 간단한 수학적 해가 제시되었다. 수학적 해를 유도하기 위하여 지반-라이닝의 경계면에서의 힘-변위 관계식을 고려하였고, 경계면에서의 상호작용을 고려하고자 새로운 계수비들을 제시하였다. 축력과 모멘트에 대한 계수비의 영향이 조사되었다.

본 연구는 아버지의 언어적 상호작용과 유아의 셀프리더십 및 유치원 적응력과의 관계를 분석하기 위하여 G시에 소재한 15개소 유아교육기관에 다니고 있는 만 4, 5세 유아 253명과 그들의 아버지 253을 대상으로 하였다. 연구결과는 아버지의 언어적 상호작용과 유아의 유치원 적응력은 통계적으로 유의한 정적 상관이 있는 것으로 나타났다. 아버지 언어적 상호작용의 하위영역인 의사소통 지향성, 화합 지향성은 유아의 셀프리더십과 통계적으로 유의한 정적 상관이 있는 것으로 나타났다. 반면에 통제지향성은 유아의 셀프리더십과 통계적으로 부적 상관이 있는 것으로 나타났다. 아버지의 언어적 상호작용과 유아의 셀프리더십은 통계적으로 유의한 정적상관이 있는 것으로 나타났다. 아버지의 언어적 상호작용의 하위영역인 의사소통 지향성에서 정적상관이 나타났으며, 반면에 통제 지향성에서는 부적상관이 있는 것으로 나타났다. 이는 유아교육현장에서 아버지와 유아의 언어적 상호작용의 중요성을 강조하여 유아교육기관의 부모교육 및 교사교육의 기초 자료로 활용하는데 도움이 되고자 한다.

Objectives: This study aims to investigate the effect of marital relationship on parenting stress among dual- and single-earner families. In particular, this study focuses on the interaction effect of marital relationship and father's child-rearing involvement on the parenting stress. To access factors associated with parenting stress, we included marital satisfaction and marital conflict as the dimensions of marital relationship in this study. Method: We employed data from the 5th wave of the Panel Study of Korean Children(PSKC) data. Our analysis sample consisted of 1,515 parents having at least one child aged under 4 years. Also, this study conducted descriptive statistics and multiple regression analysis. Results: First of all, marital satisfaction and marital conflict were significantly related to parenting stress for both mother and father in dual-earner families. While both indicators were significantly related to parenting stress for father, marital conflict only was a significant predictor for mother in single-earner families. Second, father involvement was a significant predictor for parenting stress for father in both dual- and single-earner families. Third, interaction effects were found between father involvement and marital conflict in the dual-earner families and between father involvement and marital satisfaction in the single-earner families. Conclusions: Based on the results, we recommended programs designed to enhance father's child-rearing involvement such as parenting education and community-based campaign. In addition, we recommended that policy and practice need to identify marital relationship dynamics to promote father's involvement and to reduce marital conflict in both dual- and single-earner families accordingly.

In this study, we operated science teacher learning community to enhance professionality of elementary science teachers. 8 participants with various background, which include their science content knowledge, teaching experience and beliefs about teaching, were involved in this study. Bales(1950)'s social interaction process framework was mainly used to understand the members' interaction, focusing particularly on process aspects not on contents aspects. The data analysis shows that the members in the science teacher learning community tried their best to maintain the positive reaction to other members in most occasions in the community meetings. On the other hand, there were also negative reaction process due to their different ideas and views, causing their emotional conflicts in some social relations and dialogical situations. Nevertheless, the results also imply that the dual reaction processes, which are positive and negative processes, are equally important to facilitate science teachers' professional knowledge and experience. The educational meanings are discussed in the aspects of science teacher education.

This paper presents a dynamic association and natural interaction method for multi-displays composed of smart devices. Users can intuitively associate relations among smart devices by shake gestures, flexibly modify the layout of the display by tilt gestures, and naturally interact with the multi-display by multi-touch interactions. First of all, users shake their smart devices to create and bind a group for a multi-display with a matrix configuration in an ad-hoc and collaborative situation. After the creation of the group, if needed, their display layout can be flexibly changed by tilt gestures that move the tilted device to the nearest vacant cell in the matrix configuration. During the tilt gestures, the system automatically modifies the relation, view, and configuration of the multi-display. Finally, users can interact with the multi-display through multi-touch interactions just as they interact with a single large display. Furthermore, depending on the context or role, synchronous or asynchronous mode is available to them for providing a split view or another UI. We will show the effectiveness and advantages of the proposed approach by demonstrating implementation results and evaluating the method by the usability study.

Purpose: This study aimed to identify the factors influencing the interaction between mothers and preschool-age children and construct a structural equation model based on the factors identified. Methods: The data were collected from the mothers of children aged three to six years enrolled in kindergartens in Seoul, Gyeonggi, Chungbuk, and Jeonbuk. A total of 328 questionnaires were used for the analysis. Analysis was performed using SPSS 26.0 and AMOS 26.0 programs. Results: The child's self-regulation (β = .42, p < .001) had the most significant influence on the interaction between mothers and preschool children, followed by the mother's parenting stress (β = - .23, p = .008), social support (β = .17, p < .001), and the child's active temperament (β = .15, p < .001). The child's gender, emotional temperament, social temperament, and mother's education level had indirect influences. Conclusion: These results suggest that interventions considering the child's temperament, mother's parenting stress, and social support are required to promote the interaction between preschool-age children and mothers.

This study was planned to examine the moderating effects of depression and anxiety and the relationship between online game addiction and adolescents' delinquency. Data were collected from children and youth's mental health advocacy research by National Youth Policy Institute. The subjects were 409 adolescents aged between 14 and 18. Correlational analysis and hierarchical regression analysis were conducted to test research hypotheses. Results of this study were as follows: first, online game addiction had a significant positive relations with adolescents' delinquency. Second, depression and anxiety were significant positive relations with each other. And depression and anxiety were significant positive relations with adolescents' delinquency. The result from hierarchical regression analysis showed that significant moderating effect of depression was found. But the result wasn't exhibited twithin hat the two-way interaction effects of depression. On the other hand, result from hierarchical regression analysis showed that significant moderating effect of anxiety wasn't found. In conclusion, this study proposed the need for counseling approach focused on 'depression' in order to reduce the adolescent's delinquency.

The innovative process of digitalization and creation of innovation from an idea to its commercialization requires certain financial costs, labor and mental efforts. The amount of investment (corporate and public) is the most important imperative to enhance innovation and is traditionally considered as the main "input" indicators of the development of innovation infrastructure, in this case, the financial infrastructure of innovation. At the same time, the modern theory of innovation development assumes a systematic approach to the organization of innovation activity, which provides for the close interaction of several subsystems: human (including intellectual) potential, financial and technological capital, as well as relevant institutions and methods of regulation.. Thus, the main task of the study is to analyze the features of investment support for the process of digitalization of socio-economic systems in the context of strengthening international economic relations. As a result of the study, current trends and prerequisites of investment support for the process of digitalization of socio-economic systems in the context of strengthening international economic relations were revealed.
