An agricultural infrastructure is a representative social overhead capital to promote sustainable economic growth. To maximize economic improvement through infrastructure, agricultural infrastructure should be designed effectively because its shape or form can directly influence crop productivity. However, in the agricultural field, 2D drawings and specifications, which require training to interpret, are still widely employed to build agricultural infrastructure. Hence, building information modeling (BIM), which requires that 3D models of all infrastructure types or buildings be created, has been introduced. However, this 3D model is not sufficient to create the sense of presence when the agricultural infrastructure design reviewer walks through the 3D model presented on a monitor. The building information model computer-aided virtual environment (BIM CAVE) application, originally developed by Dr. Julian Kang, Texas A&M University, is employed in this study to increase a sense of presence. The existing application was updated in 2015 by an author after the existing source code associated with the vector product was revised to synchronize nine computers which surround the user in 2015. In addition, the application was updated again to be compatible with Autodesk Navisworks 2022 or later versions instead of Autodesk Navisworks 2012. Lastly, through interviews, the feasibility of the multimonitor system based on the updated application is investigated to determine its appropriateness as an agricultural infrastructure review system.
게슈탈트 놀이프로그램이 학령후기 아동의 자기수용에 미치는 효과
김채현,김숙희 한국아동심리재활학회 2020 놀이치료연구 Vol.24 No.1
본 연구는 게슈탈트 놀이 프로그램이 학령후기 아동의 자기수용에 미치는 효과를 알아보기 위해 실시되었다. 연구 대상은 초등학교 5, 6학년 아동 12명이다. 실험집단 6명, 통제집단 6명으로 각각 무선 배치하였다. 변화를 알아보기 위해, 자기보고식 자기수용검사를 실시하였고 프로그램 평가지를 분석하였으며, 자기수용 관련 행동을 관찰하였다. 본 연구 결과는 다음과 같다. 첫째, 실험집단 아동의 자기수용 척도 점수가 사전에 비해 사후에 향상되었다. 둘째, 실험집단의 자기수용이 낮은 행동은 감소하고 자기수용이 높은 행동이 증가하는 양상을 보였다. 본 연구는 학령후기 아동의 자기수용을 증진시키는 데에 게슈탈트 놀이 프로그램이 유용할 수 있음을 시사한다. This study referred to the effects of Gestalt play program on the self-acceptance in late-school children. The subjects of this study were 5th and 6th grade in the elementary school children, Each of 6 persons was randomly assigned to the experimental and control group. To identify the change, the children's self-report peer self-acceptance tests were conducted, program evaluation were analyzed, expressions related to self-acceptance were observed. The results were as follows. First, the self-acceptance scale score of children in the experimental group was improved. Second, expressions with low self-acceptance decreased. And expressions with high self-acceptance were increased. This study suggested that The Gestalt play program could be useful for promoting the self-acceptance of late school children.
머위(Petasites japonicus)의 피부장벽과 항염증 효과

본 연구에서는 머위에탄올추출물 (PJE)의 기능성 소재로서의 활용 가능성을 알아보기 위해UVB로 유도된 Human keratinocyte (HaCaT cell)를 통해 피부장벽과 염증 개선에 대한 활성을 알아보고자 하였다. DPPH 라디칼 소거능 측정, ABTS+ 라디칼 소거능 측정, Hydrogen peroxide 소거능 측정을 통해 항산화 효과를 확인한 결과, 1 mg/ml 농도에서 대조군인 ascorbic acid과 비슷한 항산화 효과를 가지고 있음을 확인하였다. UVB로 유도된 HaCaT 세포의 filaggrin과 aquaporin-3의 생성능의mRNA의 발현을 확인해본 결과, UVB 자극에 의해 줄어든 발현량이 머위 추출물 처리 시, 농도 의존적으로 증가하고 있음을 확인하였다. TNF-α와 IL-1β의 mRNA 발현은 UVB 자극에 의해 증가되었으며 머위 추출물을 처리하였을 때 감소되는 것을 확인할 수 있었다. Migration assay 결과 농도 의존적으로 피부 각질세포의 증식과 상처의 회복율을 증가시켰음을 확인하였다. 실험결과를 바탕으로 머위가피부 보습 및 피부장벽 기능을 개선할 수 있는 기능성 소재의 화장품으로 사용될 수 있음을 시사한다.
Effect of Co-Opted Board on Audit Fees
김채현,이은서,이준엽 한국국제회계학회 2020 국제회계연구 Vol.0 No.89
In this study, we examine the effect of co-opted board on audit fees (as a proxy for audit quality), wherein the board comprises directors who are appointed after the CEO assumes office. We use two measures developed by Coles et al.(2014) to calculate the co-opted board. First, we use CO-OPTION, which is the proportion of the board size comprising the co-opted board. Second, we use TW CO-OPTION, which is the sum of co-opted directors’ tenure divided by the sum of all directors’ tenure. Using a sample of 9,592 firm-year observations in the United States for the period 2000 to 2013, we find that having a high proportion of co-opted board members leads to a decrease in audit quality. This is reflected in the negative relationship between co-opted board and audit fees. This evidence is consistent with the notion that board composition and the effectiveness of board monitoring play significant roles in determining audit fees. Overall, our results are consistent with those of prior studies that co-opted board imposes weak monitoring. In addition, our study contributes to the auditing literature by showing how board composition and monitoring effectiveness influence audit fees.
