朴娘自 瑞逸專門大學 1993 論文集 Vol.11 No.-

The present day is marked by rapid development of science and technology, and calls for creativity more than ever in the human history. It is early childhood, especially, three to six years of age, that is critical to the development of creativity, many pedagogists of children, promotes creativity of children. This study attempts to analyze how play stimulates children to develop creativity, and find what kinds of play contribute to the development of their creativity. This study shows that children express their desire and experiences through play, play increases children's response-repertoire and enables them to respond differently to similar situations. In these ways, play promotes imagination of children, and thus functions as a motive power to develop their creativity. Among others, symbolic play, an activity which is not previously planned but naturally occurning through children's own imagination, experiences, and desire, provides the richest opportunities for children to develop their creativity. It provides various kinds of opportanities for children to develop imagination, and find out new kinds and ways of activity with toys and tools they were used to playing. By so doing, symbolic play contributes greatly to creativity of children. As such, play, a natural but important activity in children's daily life, is critical to the development of children's imagination and creativity. Thus, play should be given high priority to the other educational activities for children.

Polyvinyl alcohol anthranilate (PVA-A) has been prepared by the esterification of polyvinyl alcohol (PVA) with isatoic anhydride in water in the presence of alkali at pH 9. It has been found that the reaction proceeded according to the simple second order reaction. The rate constant of the reaction has been determined by a kinetic study at 70℃, and the following rate equation which can be explained as the mechanism of the reaction has been obtained: 0.20 θ_R= 1/C_o·(x/(1-x)) The activation energy of the reaction calculated according to Arrhenius equation is 4,960 cal/mole. PVA-A and it's aqueous solution fluoresce in the ultraviolet, with a peak emission in the wave length of 255mμ~420mμ. Diazotization of granular PVA-A, followed by coupling with appropriate aromatic compounds to form colored azo dyestuffs. Especially, colorfastness to laundering and light of loth for dyed synthetic textile fiber with β-naphthol azo dye of PVA-A has been found to a good grade. The physical characteristics as paste viscosity, tensile strength and elongation of the fluorescent PVA-A are adequate for many applications.

중학교에서의 골프수업에 대한 인식과 가능성 탐색 : 하나로 수업 모형을 통하여

김낭규,김영범 이화여자대학교 교과교육연구소 2016 교과교육학연구 Vol.20 No.2

본 연구는 ‘학생들이 골프 수업을 통해 어떤 인식을 하는가?’를 파악하여 중학교에서 골프 수업의 가능성을 탐색하는 데 그 목적이 있다. 본 연구의 참여자는 중학교 1학년 남학생 8명(운동수행능력 우수학생 4명, 운동수행능력 저조학생 4명)으로 선정하였다. 설문지, 심층면담, 체육노트와 참여관찰을 통한 질적 자료수집 방법으로 자료를 수집하였으며, 귀납적 범주분석에 의해 자료를 분석하였다. 연구결과는 다음과 같다. 첫째, 수업방법적인 측면에 대한 학생들의 반응으로 각각의 터에서 골프에 대한 인식정도가 다양하였다. 배움터에서는 ‘어렵지만 도전하고 싶은 종목’으로, 하기터에서는 ‘어렵지만 재미있는 종목’으로, 쓰기터에서는 ‘복잡하지만 기대되는 종목’으로 인식하였다. 둘째, 수업 초·중반까지는 모든 학생들이 골프 수업에 관심과 흥미를 가지고 참여하였다. 수업 초·중반까지는 기능적인 어려움과 학습경험에 대한 부족함을 인지하지 못한 단계로 인해 ‘골프는 모두의 스포츠!’로 인식하였다. 하지만 골프 수업이 후반으로 갈수록 운동 수행능력의 차이에 따라 다르게 인식하였다. 운동 수행능력이 우수한 학생들은 정적이고 변화 없는 골프 수업의 운영에 대하여 소극적인 자세와 부정적인 태도를 보이는 비참여적인 모습을 보였다. 즉, 기능의 향상에 대한 학습경험의 기회를 제공받지 못함으로써 과제에 대한 지속적인 참여가 부정적으로 나타났다. 운동 수행능력이 저조한 학생들은 기존의 체육수업과는 다른 수업 방법과 교사의 긍정적인 상호작용과 관심으로 인해 과제에 대한 지속성이 유지된 것이다. The purpose of this study is to inquire the feasibility of golf class in the middle school by grasping 'how the students perceive the golf class?' The research participants in this study were 8 second grade male students of middle school(4 students with excellent exercise performance and 4 students with low exercise performance). This study employed qualitative data collection procedure such as a questionnaire, in-depth interviews, physical activity notebooks, and participant observation. The data were analyzed via the inductive categorical system. The result of this research may be summed up as follows. First, Students recognized golf as a 'difficult but rewarding sport' in learning, a ‘difficult but interesting sport’ in doing, and a ‘complicated but promising sport’ in writing. Second, all the students participated in the golf class with attention and interest from the start of class to the middle. They recognized golf as a sport for everyone. Students did not notice functional difficulties and insufficient learning until the middle of the class. However, they perceived it differently depending on their exercise performance ability as the golf class progressed into the latter stage. Students with the excellent exercise performance ability showed passive and negative attitude against golf class implementation. They were disinterested in the monotonous repetitions of the golf swing. The result of repetition revealed negative aspect of golf class. The reason for the negative result is lack of opportunity to learn golf at a deeper level. On the other hand students with low exercise performance ability could join the class willingly thanks to the teaching methods different from the existing physical education class and teachers’ positive feedback.

이상호,이난영 大韓小兒齒科學會 2000 大韓小兒齒科學會誌 Vol.27 No.1

본 연구는 치아우식을 유발 할 수 있는 모든 요인이 종합적으로 작용하여 이루어진 치면의 최초의 변화 즉, 법랑질 초기우식증의 정도를 아르곤 레이저를 이용한 형광법으로 조기에 탐지하고 이와 같은 방법이 향후 개인에서의 우식이 유발된 수 있는 가능성을 예측할 수 있는 우식활성검사법으로서의 이용 가능성이 있는지의 여부를 규명하고자 하는데 목적이 있다. 조선대학교 부속치과병원 소아치과에 내원한 아동중 유구치의 탈락이 없는 7-10세 사이의 어린이 30명을 대상으로 하여 치아의 순면과 협면에 레이저 조사하고 특수필터를 사용하여 우식치아의 개수를 측정하여 기존의 우식활성도 측정방법인 Cariescreen ?test, 구강환경검사인 우식경험치아의 수 (dDfFtT)등 각종 검사법들과 상관관계를 비교, 평가한 바 다음과 같은 결론을 얻었다. 1. 레이저형광법에 의한 관찰이 육안에 의한 관찰에 비해 초기우식병소를 더 많이 관찰하였다. 2. 아르곤게이저 형광법을 이용한 우식활성도 측정법은 기존의 Cariescreen?? test, 그리고 dDfFtT검사 등과 높은 상관관계를 나타냈다. The purpose of this study was to develop a practical caries activity test using laser fluorescence. The subjects of study were 30 children of 7-10 years old. Fluorescence from initial carious lesion of teeth illuminated by an argon laser (488nm) was observed through barrier filter. For evaluation of accuracy and propriety of this method for caries activity test, teeth with initial caries lesion on buccal or labial surface of children was examined with visual inspection and laser fluorescence. Visual examination for the dDfFtT and the Cariescreen?? test were also done. The results from the present study can be summarized as follows: 1. Laser fluorescence test could differentiate initial caries lesions more easily than visiual inspection. 2. There was highest correlation(=0.73) between laser fluorescent test and Cariescreen?? test and. And also apparent correlation (=0.66) exists between laser fluorescent test and caries experience measured by dDfFtT.

정영택,김낭규 이화여자대학교 교과교육연구소 2014 교과교육학연구 Vol.18 No.3

The purpose of this study, conducted as a research on practical cases of underprivileged female students who have been excluded from physical education in middle schools, is to search for plans to integrate those students in physical education. To achieve this goal, after applying the Hanaro Teaching Model, the responses and changes of students who have lacked physical education were observed. Six female students were selected from among the second-year students of S Middle School, located in Gyeongsangnam-do, and data was collected using qualitative methods such as observation in classes, open questionnaires, in-depth interviewing, journals for physical education, and student assignments. Collected data were analyzed using qualitative research methods, including case recording and inductive categorical analysis. In order to secure the reliability of data, peer debriefing, associate or expert consultation, and the methods of triangulation were conducted. The result summary of the study is as follows. Firstly, the practice of the Hanaro Teaching Model was carried out in the order of 'start (lesson plan and teaching objectives)' and 'action (lesson contents, class management, and teaching methods).’ In particular, we consider a class in which alienated female students can gain accomplishment and confidence, and provide positive feedback regarding the activities of students through indirect method of teaching. Secondly, there are three categories when it comes to responses and changes of alienated female students after applying hanaro teaching model in physical education class. They are forming 'looking forward to physical education class' environment by performing a task at each student's level so that she can feel fun and excitement, 'positive relationship' through activities of Tao and Pae where students can share their abilities with others, 'happiness during physical education class' through positive interaction between teachers and students. 본연구는 중학교 체육수업에서 소외된 여학생들을 대상으로 실시한실천 사례연구로서 체육소외 여학생을 체육 수업에 참여시키기 위한대안을 탐색하는데 목적이 있다. 이를위해 하나로 수업 모형을 적용시켜 체육을 기피했던 학생들이 하나로 수업 모형 적용 후 어떠한 반응과 변화를 나타냈는지 탐색하였다. 연구참여자는 경남에 소재한 S중학교 2학년 여학생 6명을 선정하여, 수업관찰(참여관찰및 비참여관찰), 개방형설문지, 심층면담, 체육일기, 학생과제물 등의 질적 방법을 이용하여 자료를 수집하였다. 수집된 자료는 질적 연구 방법인사례기록과 귀납적 분석 방법을 활용하였고, 자료의 신뢰성을 추구하기 위해 구성원 간 검토, 동료 및 전문가 협의, 삼각검증법을 실시 하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 소외 여학생에 대한 하나로 수업모형의 실천은 시작하기(수업계획, 수업목표), 활동하기(수업내용, 수업운영, 수업방법) 로 진행되었다. 특히 활동하기에서는 소외 여학생들이 역할수행을 통해 성취감과 자신감을 가질 수 있는 수업내용을 고려하였으며, 수업방법적인 측면에서는 간접교수활동을 통해 학생들의 활동에 대한 긍정적인 피드백을 제공하였다. 둘째 하나로 수업 적용 후 체육소외 여학생들의 반응과 변화는자기 수준에 맞는 과제수행을 통해 재미와 흥미를 느낌으로써 ‘기다려지는 체육’으로, 터와 패의 활동에서 자신과 타인의 능력을 공유하는 관계로 인해‘긍정적관계’로, 교사와 학생과의 긍정적 상호작용에 의해 ‘체육에서의행복’으로 범주화하였다.
