The semiotic approach to the mathematics education has been studied in last 20 years by PME, ICME conferences. New cultural developments in multi-media, digital documents and digital arts and cultures may influence mathematical education and teaching and learning activities. Hence semiotical interest in the mathematics education research and practice will be increasing. In this paper the basic ideas of semiotics, such as Peirce triad and Saussure's dyad, are introduced with some mathematical applications. There is some similarities between traditional research topics for concept, representation and social construction in mathematics education research and semiotic approach topics for the same subjects. some semiotic applications for an arithmetic problem for work, induction, deduction and abduction syllogisms with respect to Peirce's triad, its meaning in scientific discoveries and learning in geometry and symmetry.

도서관의 기본적인 목적은 지식의 생산 전달 및 사회에 대한 봉사이다. 도서관은 장서 및 정보봉사를 통해 이러한 목적을 달성하는데 기여하는 것이 필수적인 구성요소이다. 이런 목표를 달성하기 위해 장서의 질을 개선함으로써 이용자서비스의 질을 한층 더 향상시키기 위해 장서폐기가 필요하다. 하지만 현재 우리 도서관계에서는 장서 폐기의 중요성을 어느 정도 인식하고 있지만 회피하는 경향이 있다. 이러한 이유로 각 도서관별 장서의 양에 따라 도서관의 순위를 매기는 정책 요인과 실무 요인, 행정 요인 등이 있다. 결국 장서폐기에 대한 필요성은 인식하고 있지만 쉽게 실천을 못하는 실정이다. 장서폐기는 부족한 서고 공간 문제에 대한 해결책이 될 수 있을 뿐 아니라 장서의 품질관리를 위해서도 필수적인 활동이다. 따라서 장서폐기에 대한 필요성과 그에 따르는 저해요인을 분석함으로써 현실적인 도서관 관리를 재조명하고자 한다.

Contemporary literary writers engage in multiple jobs and activities in the changing industrial and institutional environments to manage careers and produce literary value. The notion of art entrepreneurship envisages writers as the actors pursuing optimal rewards at both literary and economic levels by applying creative knowledge and skills to the management of career. In contrast, the notion of creative labor argues that writers go through career insecurity as they pursue self-fulfillment through work. This paper critically reviews two notions and suggests the notion of cultural intermediaries to better understand their production of literary value within the variety of relational contexts where they are situated. This paper analyzes the structures and characteristics of a wide range of intermediary practices by literary writers. Based on the analysis, I argue that the autonomy of literary value the writers construct and their status of entrepreneur-labourer are contingent upon the relational contexts within which they practice the intermediary work. I also suggest that literary writers by utilizing a variety of tactics cope with the changes that shape the autonomy of literature and invent new roles and identities as cultural intermediaries. Furthermore, literary writers develop not only self-management skills to adapt to the changing environments but also the collective capacity to cope with the constraints derived from the structural change of literary production and circulation. Finally, I argue that the art management discipline can reflect upon and support the creative endeavors of literary writers by embracing the critical understanding of structural changes suggested by the disciplines of humanities and social sciences.

This study recognizes that the externalizing problem behaviors of child with disabilities are the result of the social interaction between mother and child, and empirically verifies its systematic causal structure and multidimensional influence relationship. It was attempted to derive practical implications that can help the smooth normalization process of children's families. Therefore, 135 children with disabilities and their mothers selected by convenience sampling were targeted, and in the relationship between maternal overprotective parenting and externalizing behaviors of child, effortful control was used as a mediating variable, and defense style of mothers and children was used as a moderating variable. A Conditional Process Analysis(CPA) that can verify the moderated mediation Effect was performed by establishing a research model. As a result of the analysis, first, the overprotective parenting behavior of mother was statistically significant in both direct and indirect effects in increasing externalizing behaviors of child, and the mediation effect by effortful control was also statistically significant. Second, it was confirmed that the moderated mediation effect of effortful control by the mother's defense style was statistically significant, and the moderated mediation effect of effortful control by the child's defense style was not statistically significant. Based on the above results, assuming the importance of the influence of maternal parenting, a direct strategy for change in maternal overprotective parenting, child's Practical implications of parallel strategies with the tendency toward effective control and suboptimal strategies through the application of mothers' coping strategies were discussed.

This study aims to analyze influences of self-perceived health, participation in social activities on life satisfaction and mediating effect of participation in social activities of the elderly by age group. For this, Structural Equation Model(SEM) was implemented by using data of the 6th wave of KLoSA with 2,106 young-olds and 2,219 old-olds. The results are as follows: The young-old elderly had higher level of self-perceived health, higher participation in social activities, and higher life satisfaction than the old-old elderly, and the mediating effect of participation in social activities was founded only in the young-old elderly. As a result of multi-group analysis, the influence of self-perceived health on life satisfaction was confirmed by no difference between both groups and the influence of self-perceived health on the participation in social activities was relatively higher in the old-old elderly. In the path of participation in social activities on the life satisfaction, the young-old elderly were found to have a significant effect. Through above results, the intervention plan considering the differences between groups was discussed in order to improve the elderly's life satisfaction.

The concept of citizen science(CS) is defined as "scientific work carried out by citizens." Here, 'citizen' means someone who has knowledge of everyday life, regardless of whether they have formal expertise in a related field. This definition may encompass scientists, as many scientists participate in scientific democracy and use their expertise in a citizen-oriented manner. That work is derived from their citizenship, so their scientific work is CS. CS in Korea has expanded from the Korea Pollution Research Institute, which was founded in 1982, to the Center for Democracy in Science & Technology, which was founded in 1997. Furthermore, in recent years, government agencies have started using CS approach. In this paper, I introduce Korean CS and examine its accomplishments and difficulties through eight cases. I show that Korea's CS activities have made a significant impact on Korean society and the experience of these activities has implications for the future directions of CS. I do so by examining four modes of CS and explore practical messages for more varied roles of CS. Until now CS has been mainly considered in the context of "CS as education" or "CS as movement" in Korea. However, governance and the platform mode of social decision-making or research, though still rare, have recently emerged as additional CS activities. Although it cannot be said with certainty that CS is better, it is undoubtedly better the more varieties of its modes coexist. The four types of CS will contribute individually or complementarily to social learning. Thus, because of its distinctive potential, CS is not exhausted by the supplementary concept of science.

This study aims to verify the mediating effect of mobile social participation on the relationship between the mobile device capability and life satisfaction. Using the data of 2018 Digital Divide Survey conducted by the National Information Society Agency(NIA), the mediating effect was verified by Baron & Kenny (1986)'s 3 step process, targeting 1,665 middle and older aged adults. The result is as follows: first, the mobile device capability of the middle and older aged people has a positive effect on life satisfaction. Second, the effect of the mobile device capability of middle and older aged people on life satisfaction is partially mediated by mobile social participation including expressing opinions on social concerns, proposing policies and filing a civil complaint, donation and volunteering work and online voting and responding to a poll. The result represents that the mobile device, such as a smart phone or a smart pad, capability of the middle and older aged group not only directly benefits the group but also helps expand their mobile social participation, which leads to, although indirectly, higher life satisfaction. Therefore, the study is expected to be a groundwork for a practical intervention for enlarging the use of mobile device and lifting digital information level of the elderly to encourage mobile social participation and drive life satisfaction.

The primary goal of the current study was to investigate the longitudinal relationship between household income, main caregiver depression, and youth aggression from the interactionist perspective. The data were derived by combining the 2006, 2009 and 2012 survey waves from the Korean Welfare Panel Study. This data set covered the full span of adolescence from elementary to high school. The study utilized 561 families as the final sample and conducted autoregressive cross-lagged analysis. As a result, the early income status, main caregiver depression and youth aggression were likely maintained over time. Second, the results provided support for a reciprocal relationship between income and main caregiver depression. On the other hand, the reciprocal relationship between main caregiver depression and youth aggression was not found in the current study. Finally, the mediating effect of main caregiver depression between income and youth aggression was not found in the present study. In conclusion, the results of this study support the interactionist model in that the association between family income and main caregiver depression involves reciprocity and mutual influence across time. These findings have major implications for policy and interventions in regards to low-income families.

The moral corruption or the reality of absence of humanity derived from the development of science and society is very serious. Especially the moral education which should provide new breakthroughs facing such issue will be the initial concern in the educational world and the key point that judges our future. This study, as a part of efforts made for such demands of the times, is an attempt to approach the field of the present elementary education specifically by deducing the abundant meaning that the Confucianism's Chungseojidoh(忠恕之道: the principle of "Faithfulness" and "Benevolence") stands for. To build an ethical social community also means to draw voluntary moral practices into this society and this is possible with our (the moral subject) struggling the problems within but not remaining in the limitations of physical norms. Chungseojidoh as universal ethics contains a virtue ethical meaning as Jenlogy, a meaning of identity recognition and self-esteem inspiration, a meaning of social community ethics as ethics of good offices, etc. Such meanings, in particular, can be discussed more profoundly in terms of educational prevention from violence or cliquish issues in school that are largely related to education of humanity if 'applying schemes for elementary education' is seen as the center of the issue. And furthermore, they will be able to open a discussion over problems of the situation which the Korean society is in - especially the insistence, egoism or conflicts between social communities - can be answered in actuality.
