The purpose of this study is to analyze the effect of trust and identification with physical education teachers on empathy and personality of secondary school students. To this end, a survey was conducted on 479 secondary school students, and as a result, the following conclusions were obtained. First, in terms of gender, male students were higher than female students in the ‘intimacy’ factor of the physical education teacher trust and the ‘confidence’ factor of character. Also, in all factors of empathy, female students were higher than male students. By grade, middle school students were higher than high school students in terms of class composition and athletic ability factors among the PE teacher trust factors. Second, there was a high correlation between the physical education teacher trust and identification, and all factors of empathy and character. Third, trust in physical education teacher had a significant effect on empathy and character. In particular, among PE teacher trust, ‘fairness’ had a meaningful effect on all factors of empathy, and ‘intimacy’ had a meaningful effect on all factors of character. Therefore, in order to cultivate the empathy ability and correct character of secondary school students, it is necessary to play a role of a physical education teacher whom students can trust and admire.

황성하(Hwang, Sung-Ha) 한국체육과학회 2021 한국체육과학회지 Vol.30 No.1

The purpose of this study is to understand the perceptions of student athletes, parents, and coaches, who are the subjects of school athletic sports about fostering studying-student-athletes. To achieve this purpose, 3 student athletes, 3 coaches, and 2 parents were selected as research participants. The data were collected by in-depth interview, and the collected data was analyzed by textual analysis. As a result, there were three major perceptions of the school athletic sports operator on fostering studying-student-athlete. The first was ‘the absence of a practical element capable of realizing the structure’. The gap between policy and reality was producing negative perceptions about fostering studying-student-athlete. The second was ‘dichotomous thinking based on false success discourse’. The false discourse of success about sports stars fixed the belief that exercise is the only way to success. This served as a driving force for solidifying the dichotomy between study and exercise. The third was ‘the narrow gaze at the student athlete and the tacit avoidance of schoolwork’. The skeptical questions and reactions to the student athletes who are studying acted as a mechanism for implicit avoidance of schoolwork for the student athletes.

The purpose of this study was to analyze factors that affect the continuity of leisure sports participation among employed workers. To collect data, 728 of the employed workers affiliated with a leisure sports club in D city were selected through stratified cluster random sampling and surveyed with an open-ended questionnaire. Collected data were processed through inductive categorical analysis. The results of the study are as follows:First, there is a social factor that affects the continuity of leisure sports participation among employed workers. Many respondents participated in sports to form social relations. So, in order to encourage employed workers to continuously participate in sports, it will be necessary to promote sports clubs activities in communities as well as in workplaces. Second, there is a physical factor that affects the continuity of leisure sports participation among employed workers. It was found that the continuity of leisure sports participation was closely related to physical development and enhancement. In addition, many people participated in sports activities for self-defense. Third, there is a psychological factor that affects the continuity of leisure sports participation among employed workers. Many respondents participated in sports activities to relieve stress from work and home. Thus, various sports programs should be developed in order to motivate employed workers to continuously participate in sports activities. Fourth, there is an environmental factor that affects the continuity of leisure sports participation among employed workers. It is not easy for employed workers to find time for leisure and cultural activities out of busy schedule. However, once people are committed to leisure and cultural activities, they tend to continue those activities rather than changing them. Because sports activities are part of leisure culture, this tendency will also apply to people``s participation in sports.

The purpose of this narrative study is to understand the various thoughts and emotions experienced as preliminary physical education teachers who were student athletes during the preparation process for the teacher recruitment examination, and to explore the social and educational implications of them. The research participant was selected as physical education teacher who passed the examination after three attempts, who was former student athletes using the decisive case sampling method. The data were collected in-depth interview, and the collected data were analyzed through inductive category analysis. Through the research participant Jung-Hyun"s ‘opinion’ I was able to understand the meaning, contradictions and improvements of the life of a preliminary physical education teacher. There are three main reasons for the hardships of life experienced by a preliminary physical education teacher in preparing for the teacher recruitment examination, and the first was the ‘lack of academic ability caused by failure to study and exercise at the same time’. Limits were revealed not only in basic learning, but also in posture, attitude, and career commitment. The second was ‘structural problems arising from the system of fostering student athletes’. The anguish of the preparation process for the theoretical test was not only a problem of individual effort or competence, but also a problem of wrong student athletes training system. The third is ‘biased socio-cultural awareness of student athletes.’ The socio-cultural perception that only hard work in sports can succeed served as a driving force behind the biased implicit belief.

황성하(Sung Ha Hwang) 한국체육교육학회 2010 한국체육교육학회지 Vol.15 No.3

본 연구는 스포츠교육모형을 적용한 체육수업이 신체활동의 즐거움 및 대인관계성향에 미치는 영향을 알아봄으로써 심리·사회학적인 관점에서의 분석과 교육적인 가치를 모색해 보는데 그 목적을 두고 있다. 이를 위해 중학교 1학년 4개 학급 132명을 대상으로 선정하여 연구를 진행하였다. 남·여 학급의 단위별로 스포츠교육모형을 적용한 실험집단 66명과 기능중심 수업모형을 적용한 통제집단 66명으로 분류하였다. 연구절차는 실험처지 전 사전검사를 실시하였으며, 실험집단에는 스포츠교육모형을 적용하였고, 통제집단에는 기능중심 수업모형을 적용하여 주3회 18차시의 수업을 실시한 후 사후 검사를 실시하였다. 사전·사후 검사를 통해 나타난 결과는 SPSS WIN-15.0을 이용하여 t검증 및 공변량분석(ANCOVA)을 통해 분석되었고, 다음과 같은 결론을 얻을 수 있었다. 첫째, 스포츠교육모형을 적용한 체육수업은 신체활동의 즐거움(자신감, 재미, 건강유지 및 미적체험, 협동심, 창의성)의 향상에 유의한 영향을 미치는 것으로 나타났다. 둘째, 스포츠교육모형을 적용한 체육수업은 대인관계성향 중 타인지향성과 규범지향성의 향상에 유의한 영향을 미치는 것으로 나타났으며, 기능중심 수업모형은 개인지향성의 향상에 유의한 영향을 미치는 것으로 나타났다. The aim of this study is to find out the educational value of the P.E. class with Sports Education Model and to analyze it in a socio-psychological viewpoint. Participants(132 first graders of D middle school) were divided into two groups: one with Sports Education Model embedded class as an experimental group and the other with function-oriented model. As the instruments of measurement, this study made use of (i) ``Checklists for Pleasure of Physical Activities`` and (ii) the modified checklists based on the ``The Development of the Directivity of Personal Relationship`` and ``An Experiential Approach - The Development of the Measurement of the Directivity of Personal Relationship``. After the execution of a pre-test, the experimental group was treated with Sports Education Model and the control group with Function-Oriented Model three times a week(18 periods in total), then both group took the post-tests to analyze and compare the results of the pre and post tests. Through the whole procedure, we reached the conclusion as following: First, it is found that the Sports Education Model embedded classes have meaningful influence on students` affective domain during the P. E. Classes. Second, Sports Education Model embedded class affects greatly on promoting an inclination of personal relationship especially on other-directedness and norm consciousness, while the classes based on function-oriented model have effect on self-directedness. Based on this study, Sports Education Model embedded P.E. class makes it possible for the teachers to manage more exciting P.E. classes. Furthermore, both direct and indirect experiences that students have got during the class seems to foster the consideration on others and observation of rules.

코로나19 상황에서 체육교사의 학교스포츠클럽 운영경험에 대한 내러티브 탐구

황성하(Hwang, Sung Ha) 한국체육교육학회 2021 한국체육교육학회지 Vol.26 No.3

목적: 이 내러티브 연구의 목적은 코로나19 상황에서 학교스포츠클럽을 운영한 체육교사의 운영경험을 이해하고, 그 안에 내포되어 있는 교육적 의미를 탐색하는 데 있다. 방법: 연구참여자는 결정적 사례표집법에 의해 코로나19 상황에서도 학교스포츠클럽 운영에 전념한 체육교사로 선정하였다. 자료는 심층면담으로 수집하였고, 수집된 자료는 넓게 바라보기와 깊게 바라보기를 병행하면서 텍스트화, 개념 생성, 상위‧하위범주 생성, 주제 생성의 과정을 거치면서 분석하였다. 결과: 코로나19 상황에서 학교스포츠클럽을 운영한 김교사의 이야기는 다시 이야기하는 과정에서 세 가지의 교육적 의미를 주었다. 그것의 첫 번째는 ‘신체활동 욕구의 충족과 일탈행위 예방’이고, 두 번째는 ‘능동적인 참여와 안전교육의 실현’이다. 마지막 세 번째는 ‘거리두기 속 새로운 또래관계 형성’이다. 결론: 코로나19 상황에서 학교스포츠클럽은 학생들의 신체활동 욕구를 충족시켜 일탈행위를 예방했다. 또한 코로나19 상황에서 제한된 활동만 하는 학생들에게 안전한 스포츠 환경을 제공해 능동적인 참여를 이끌었고, 학생 스스로 코로나19를 경계하는 기제로 작용했다. 더불어 거리두기 속에서 ‘넷볼’이라는 공통의 주제를 생성해 학생들의 상호작용을 지원했으며, 이를 바탕으로 새로운 또래관계를 형성하는데 기여했다. 따라서 코로나19 상황에서 학교스포츠클럽 운영 자체를 위험 요소로 인식하고 무조건 배제하거나 축소하는 교육 실천은 지양하고, 학생들이 안전하게 학교스포츠클럽에 참여할 수 있는 환경과 지원체계를 마련해야 한다. Purpose: The purpose of this narrative study is to understand the operating experience of a physical education teacher who operated a school sports club in the context of COVID-19, and to explore the educational meaning contained in it. Methods: The study participants were selected as physical education teachers who operated a school sports club under the COVID-19 situation according to the decisive case sampling method. The data were collected in-depth interview, and the collected data were analyzed through the processes of textualization, conceptualization, formation of uppper/sub category, and formation of themes. Results: The story of Teacher Kim, who ran a school sports club in the situation of COVID-19, gave three educational meanings in the process of re-storying. The first is "satisfaction of physical activity needs and prevention of deviant behavior", and the second is "realization of active participation and safety education". The third is ‘formation of new peer relationships while social distancing’. Conclusion: The school sports club, operated under the supervision of a physical education teacher at a school with guaranteed safety, prevented school violence by satisfying the students" needs for physical activity, and acted as a mechanism for self-guarding against COVID-19. In addition, they created a common theme of netball while social distancing, helping to form new peer relationships. Therefore, rather than a biased view that unconditionally opposes school sports clubs in the COVID-19 situation, it is necessary to prepare an environment and conditions for school sports clubs to operate safely.

황성하(Sung Ha Hwang),김동현(Dong Hyun Kim) 대한안과학회 2017 대한안과학회지 Vol.58 No.6

Purpose: We report a case of spontaneous corneal perforation combined with primary pterygium. Case summary: A 66-year-old male presented with a foreign body sensation in his right eye. He had no systemic or ocular inflammatory diseases. He had undergone penetrating keratoplasty following amniotic membrane transplantation for corneal perforation at 1 day after pterygium excision in his left eye. The uncorrected visual acuity (UCVA) and intraocular pressure (IOP) in his right eye were 0.8 and 2 mmHg, respectively. Active leakage of an aqueous humor on the head of the pterygium was found on slit lamp examination. With the impression of spontaneous corneal perforation combined with primary pterygium, emergent amniotic membrane transplantation was performed. Diffuse corneal thinning around the 2 mm-sized perforation site was found 3mm away from the limbus in the 5 o’clock after removing the pterygium. The perforation site was covered with amniotic membrane after applying fibrin glue. UCVA and IOP in his right eye were 1.0 and 9 mmHg, respectively, at postoperative 6 months. No definite recurrence of pterygium or additional corneal perforation was found. Conclusion: Spontaneous corneal perforation may be related to primary pterygium. 목적: 원발군날개와 동반된 자발적 각막 천공 1예를 보고하고자 한다. 증례요약: 66세 남자가 하루 전부터 발생한 우안의 이물감 및 눈물흘림을 주소로 내원하였다. 전신적인 특이병력은 없었으며, 6년전 좌안 군날개에 대해 타 병원에서 군날개절제술을 시행 후 하루만에 발생한 각막 천공으로 응급 양막이식술을 시행 받고, 이후 전층각막이식술을 받은 과거력이 있었다. 내원 시 우안 나안시력은 20/25, 안압은 2 mmHg였다. 세극등현미경 소견상 우안은 비측 군날개가 관찰되었고, 군날개 머리 부분 아래로 각막의 활동성 방수 누출이 관찰되었다. 군날개와 동반된 각막 천공 의심하에 응급 양막이식술을 진행하였다. 군날개를 제거한 뒤 5시 방향 윤부에서 3 mm 떨어진 각막에 2 mm 크기의 천공 부위가 관찰되었으며, 천공 주변으로 각막이 전반적으로 얇아져 있었다. 천공부위 위로 피브린 글루를 도포 후, 양막이식술을 시행하였다. 수술 후 6개월뒤 우안 교정시력 20/20, 안압 9 mmHg였으며 추가적인 천공이나 군날개 재발 등의 합병증은 관찰되지 않았다. 결론: 원발군날개 환자에서 자연적으로 각막 천공이 발생할 수도 있으므로, 군날개 진료 시 이에 대한 가능성에 대해서도 고려해야할 것으로 생각된다.
