학령 초기 아동의 미디어 이용시간과 어머니의 양육스트레스가 학교적응에 미치는 종단적 영향: 집행기능 곤란의 매개효과

This study examined the longitudinal effects of media usage by early school-age children and of maternal parenting stress on children's school adjustment. The study focused on the mediating effect of executive function difficulty. Longitudinal data to examine the hypothetical model were drawn from the eighth (2015) through tenth (2017) waves of the Panel Study of Korean Children (PSKC) collected by the Korea Institute of Child Care and Education (KICCE). A total of 581 children (293 boys and 288 girls) and their mothers were included. Confirmatory factor analysis, structural equation model, and bootstrapping analysis were applied using SPSS 25.0 and Amos 26.0. The results are as follows. First, no significant correlation was found between early school-age children's media usage and maternal parenting stress. Second, neither media usage by early school-age children nor maternal parenting stress were found to directly affect children's school adjustment. Third, media usage by early school-age children and maternal parenting stress were shown to indirectly affect children's school adjustment via executive function difficulties. In other words, higher levels of media usage by early school-age children and maternal parenting stress during the first grade lead to greater executive function difficulties after a year, which, in turn, lead to a lower level of school adjustment in the third grade. This study indicates the need to develop practical support for the psychological wellbeing of mothers while they are performing their role as a parent and for children in maintaining suitable levels of media usage during early childhood.

세계화의 영향에 따른 물자, 자본, 노동력의 교환이 증가함에 따라, 다양한 사회적 주체들과의 협업방식을 탐구하는 협업적 미술, 또는 참여미술이 현대미술의 주요한 형태로 성장하였다. 김홍석은 배우, 미술비평가, 미술관 도슨트, 일용직 노동자, 그리고 가상의 외국인 노동자 등 사회의 다양한 주체들과의 협업을 통해 미술제작과정에 발생하는 자본과 노동의 교환을 탐구해 온 대표적인 한국 작가이다. 본 논문은 김홍석의 번역관련 작업에서 주로 논의되어온 그의 텍스트 사용에 대한 연구에서 벗어나, 협업 작업 속 텍스트의 사용과 텍스트적 생산에 대해 주목하고자 한다. 김홍석은 협업 작업 속에서 텍스트를 사용하여 예술적, 사회적, 지적 노동을 작업 속에 교차시키고, 또한 작가, 참여자, 관객 간의 관계를 재정의하고 그들의 대화를 중재하고자 하는 시도를 보였다. 나아가 김홍석은 미술관 공간을 사회적 소통의 공간으로 전환시켜 미술의 생산과, 유통, 그리고 수용 과정에 대한 토론들을 생산하고자 했다. 본 논문에서는 김홍석의 협업 작업에서 발생하는 다층적인 대화와 텍스트 생산을 분석하여 김홍석의 작업이 협업 미술의 방식과 사고를 어떻게 확장하고, 또한 협업 미술에 대한 담론적 생산에 어떻게 기여하고 있는지에 대해 논의하고자 한다. With the increased exchange of product, capital, and labor, contemporary artists have explored ways of working with different subjects and techniques, and collaborative art is accepted as one of the major artistic practices. Gimhongsok creates his works based on collaborative practices with different subjects, including actors, museum docents, laborers, art critics, viewers, and fictional immigrant workers, and also explores issues of authorship, copyright, financial compensation, and the moral and ethical problems that occur within collaborative artistic production. This paper investigates Gim’s collaborative projects focusing on his use of texts and textual production within his works. Gim’s use of text has been discussed frequently in relation to his works on the serial translation, but text also plays a significant role in his collaborative works. Gim not only creates the exchange of artistic, social, and intellectual labor within his collaborative projects, but also redefines the relationships among the artist, participants, and viewers and mediates their communications through the use of texts. By transforming a gallery into part of a social communication space, Gim’s collaborative practices not only creates an opportunity to rethink the methodologies of collaborative art, but also to expand discourse on the production, circulation, and reception of art in the global art world.

Cells regulate their shapes and motility by sensing the cues from the internal and external microenvironment. Under different circumstances, microglia, the brain resident immune cells, undergo dynamic phenotypic changes, one of which is a remarkable periodic oscillatory migration in vitro. However, very little is known about the kinematic and dynamic perspectives of this oscillatory behavior. In this study, we tracked the changes in cell morphology and nuclear displacement, and visualized the forces using traction force microscopy (TFM). By correlation analyses, we confirmed that the lamellipodia formation preceded the nuclear translocation. Moreover, traction, developed following lamellipodia formation, was found to be localized and fluctuated at two ends of the oscillating cells. Taken together, our results imply that oscillatory microglial cells feature a viscoelastic migration, which will contribute to the field of cell mechanics.

Small enterprise suffer harsh competitive society because of there small business size. They need some method to overcome obstacles. I expect that the increase of size to help them compete for major company. Thus, I suggest group purchase to the small enterprise. The group purchase makes their bargaining power increase and grow their business profit. Some organization of group purchase have a role to play in U.S, Germany, Australia. However, there is no systematic support system of group purchase in Korea. That's why I study the plan of group purchase business model.
비교할 특징점의 제한을 통한 지문 인식 시스템의 성능 개선

기존의 지문 인식 시스템은 입력 영상이 회전되지 않는다는 가정 하에서 진행되어 왔다. 입력 영상이 회전되었을 경우에는 특징점의 위치가 많이 달라지기 때문에 정확한 매칭경과를 기대할 수 없다. 따라서 회전에 무관한 지문 인식을 위해 제한된 범위에서만 회전에 무관하게 지문을 인식할 수 있는 방법이 제시되기도 하고 범위를 제한하지 않은 알고리즘도 소개되었으나 특징점 간의 비교수가 많다는 문제점이 있다. 본 연구에서는 기존의 회전에 무관한 지문 인식 알고리즘을 이용하되 비교할 특징점의 대상을 줄여 처리 속도를 향상시킬 수 있는 방법을 제안하고 실험을 통해 그 타당성을 제시한다.
