정호연,김진호 한국특수교육학회 2018 특수교육학연구 Vol.53 No.3
Educational drama usually means the educational activities and methods that use drama for the purpose of education. This study investigated the effects of an educational drama program on the social interactions of elementary students with intellectual disabilities in special education classes. The participants in this study were 16 elementary school students in special education classes in three elementary schools located in Chungbuck Province. The study consisted of intervention settings and general settings and used a multiple-baseline experimental design across the three groups of participants. The experimental phases were set up as baseline, intervention, and maintenance; in each stage generalization observations were also conducted. The intervention through the educational drama program included a total of 14 sessions. Data was measured through recorded videos of the social interactions and presented in a graph that was used to analyze the changes in social interaction. The results were as follows: First, throughout the study, social initiation occurred and positive effects were seen during treatment sessions as well as maintenance sessions. Second, after conducting the educational drama program, social reaction was observed to occur among the subjects and positive effects were also seen during treatment and maintenance sessions. Third, there was a positive effect of the educational drama program to improve social interactions of the participants. Based on the results, this study suggests that educational drama programs may be meaningful and effective educational activities to increase social interaction skills of elementary students with intellectual disabilities in special education sites. 교육연극은 교육을 목적으로 연극을 활용하는 교육 활동 및 방법을 의미한다. 본 연구는 교육연극 프로그램이 초등 지적장애 학생의 사회적 상호작용에 미치는 효과를 알아보는데 목적을 두었다. 이를 위하여 충북에 위치한 3개 초등학교 특수학급 지적장애학생 16명(각 학교 별 5명, 7명, 4명)을 대상으로 하였다. 먼저 대상자 집단 간(세 학교 간) 중다 간헐 기초선 설계를 사용하여 집단 간의 중재 효과를 살펴보고, 이어서 개별학생에 대한 효과를 알아보기 위하여 개별 대상자 간 중다 간헐 기초선 설계를 사용하여 각 대상학생에 대한 중재프로그램의 효과도 살펴보았다. 중재효과의 일반화는 기초선, 중재, 유지단계에 따라 측정하였다. 중재는 교육연극 프로그램으로 내용타당도를 검증 받았으며, 총 14회기로 구성되어 일주일에 1~2회기 씩 한 회기에 80분 동안 실시되었다. 연구 결과를 보면 교육연극 프로그램을 실시한 후에 대상학생들은 사회적 시작행동, 사회적 반응행동, 사회적 상호작용의 발생과 그 유지, 일반화에 긍정적인 효과를 보였으며, 개별학생의 사회적 시작행동과 사회적 반응행동의 발생과 유지, 일반화에도 긍정적인 효과를 보였다.

In the production of art ornaments expressing the Artist's thoughts the adopting of materials plays an important role in the expression of the subject. The purpose of this study is to study expressions and techniques for applying the interpretation of time to jewelry work using polyester mesh through the researcher's jewelry 'Time' series. To this end the author's case study which applied the characteristics of polyester mesh and mesh shape to jewelry showed the characteristics of plastic forming using the gap between projection and mesh and the weaving of mesh that can be made by hand work. The "Time" series organizes the interpretation of time into images, memories and repetitions and first the image focuses on colors expressed by the junction of polyester mesh and organza. The expression of the second image used thermoplasticity of polyester to study the three-dimensional forming method using urinary iron and the projection of polyester mesh was utilized. Repetition was a feature of the light weight of polyester which showed that it was free to repeat and possible to form space between objects. Through the expression study of polyester mesh for expression of time, we have learned the possibility of superposition using wearing lightness and projection, color concentration expression and stereoscopic formation and hope that polyester mesh can be applied to jewelry work through this study. 재료의 대입은 작가의 생각을 표현하는 예술 장신구 제작에서 주제의 전달에 중요한 역할을 한다. 본 연구는 연구자의 장신구 ‘시간(時間)’ 시리즈를 통하여 폴리에스터 메시를 이용하여 시간의 해석을 장신구 작업에 적용하기 위한 표현과 기법의 연구에 목적이 있다. 이를 위해 폴리에스터 메시의 특징과 메시 형태를 장신구에 적용한 작가 사례연구를 통해 투영성과 메시의 간격을 이용한 성형의 특징, 수공작업으로 만들 수 있는 메시의 짜임에 대해 알 수 있었다. 본 연구자의 장신구 ‘시간(時間)’ 시리즈는 시간의 해석을 이미지, 기억, 반복으로 정리하고 먼저 이미지는 폴리에스터 메시와 오간자의 접합으로 표현되는 색상에 중점을 두었다. 두 번째 이미지의 표현은 폴리에스터의 열가소성을 이용하여 요철을 이용한 입체성형 방법을 연구하였고 폴리에스터 메시의 투영성을 활용하였다. 반복의 표현은 폴리에스터의 가벼운 중량의 특징으로 반복적 표현이 자유로우며 개체 사이의 공간 형성이 가능함을 알 수 있었다. 시간의 표현을 위한 폴리에스터 메시의 표현연구를 통해 착용상의 가벼움과 투영성을 이용한 중첩의 표현, 색채의 표현, 입체성형의 가능성을 알게 되었으며 본 연구의 표현기법을 통해 폴리에스터 메시가 장신구 작업에 응용될 수 있기를 희망한다.

Actinomycosis is a common chronic suppurative and granulomatous infection caused by anaerobic or microphilic bacteria primarily from the genus Actinomyces. However, Actinomyces is a rare cause of pericarditis. We experienced a rare case of pericardial actinomycosis. A previously healthy 44-year-old man presented with 3 days of fever, chest pain, and clinical signs of congestive heart failure. Chest computed tomography showed pericardial effusion, pericardial thickening, and bilateral pleural effusion. A subxiphoidpericardiotomy was performed, and a histological specimen was taken from the pericardium. A histological section of the pericardium showed an actinomycotic granule (sulfur granule). His symptoms and signs improved after administration of piperacillin/tazobactam and steroids. He was uneventfully discharged on oral amoxicillin/clavulanate. He recovered fully with no recurrence after six months of follow-up.

Rolling noise, a type of railway noise, is generated by the vibration of rails and wheels. A proper noise reduction method for rolling noise is necessary. In this paper, experimental analysis was conducted on rail response reduction effect of a rail impact particle damper to reduce rolling noise. A comparison of rail responses before and after installation of the impact particle damper was performed. It was confirmed that the rail displacement decreased by an average of 15% and the stress decreased by about 19% after installation of the damper. It was also confirmed that the rail acceleration decreased by 27%. It was confirmed that the impact particle damper is effective not only at reducing rolling noise but also at reducing rail responses such as acceleration, displacement, and stress.

The purpose of this study is to investigate how the satisfaction of start-up business support affects the financial performance in order to provide theoretical and practical implications to the institutions and practitioners who run start-up support projects. The start-up business support are classified as external support and internal support, The relationship between organizational trust and financial performance was analyzed by corporate performance. In particular, the mediating effect of organizational trust was verified. For this purpose, a questionnaire survey was conducted from January 2 to February 1, 2018 for companies in the business incubation center related to carbon composite materials. A total of 247 responses were used for statistical analysis. Empirical analysis was carried out using reliability analysis, factor analysis, and correlation analysis using SPSS 23, and confirmatory factor analysis, structural equation model analysis and path analysis were conducted by Amos 23. First, the satisfaction of prototype, marketing, financial accounting, education, and consulting of start-up business support affects the financial performance positively, but the law does not affect the financial performance. Second, education and consulting, which are internal support of start-up business support, have positive effect on financial performance through organizational trust. In addition marketing and financial, which are external support, accounting did not show the indirect effect of trust between organizations but only direct effect on financial performance. This implies that programs for organizational trust should be considered in the case of internal support such as education and consulting. 본 연구에서는 창업지원사업을 실시하는 기관 및 실무자에게 이론적 실무적 시사점을 제공하고자 창업지원사업의 만족이 조직신뢰와 경영성과에 어떠한 영향을 미치는지를 살펴보고자 창업지원사업의 만족과 조직신뢰 및 경영성과의 관계를 실증분석하였으며 특히 조직신뢰의 매개효과를 검증하였다. 이를 위해 창업보육센터에 입주한 기업을 대상으로 2018년 7월 2일부터 8월 5일까지 설문조사를 실시하였으며 총 247개의 응답을 받아 통계분석에 사용하였다. 실증분석은 SPSS 23을 활용하여 신뢰도분석, 탐색적요인분석, 확인적요인분석, 상관관계분석을 실시하였으며 Amos 23을 통해 확인적요인분석, 구조방정식모형분석과 가설검증을 진행하였다. 분석결과 첫째, 창업지원사업의 시제품, 마케팅, 재무회계, 교육, 컨설팅에 대한 만족은 경영성과에 정(+)의 영향을 미치는 것을 확인하였으나 법률은 경영성과에 영향을 미치지 않는 것으로 나타났다. 둘째, 경영성과에 영향을 미치는 않은 법률을 제외한 창업지원사업의 교육과 컨설팅은 조직신뢰를 매개로 경영성과에 정(+)의 영향을 미치고 마케팅, 재무회계는 조직간 신뢰의 간접효과는 나타나지 않고 경영성과에 정(+)의 직접효과만 나타났다. 이는 교육과 컨설팅과 같은 지원사업의 경우 조직신뢰를 위한 프로그램을 고려해야 함을 의미한다.
