This paper describes the development of sputtered tungsten electrode for discharge tube by making use of Sputtering method using plasma. The Xe discharge tube was designed and fabricated by using sputtered tungsten electrode, and the ICCD(Intensified Charged Coupled Device) and monochromator were used in order to observe the discharge image distribution and to measure the signal intensity. As a result, the emission light form the electrode was spreaded almost uniformly over a wide wavelength band, and the discharge image distribution and the signal intensity show quite a uniform distribution. The emission light from the Xe discharge tube was peaked at 488[nm] and 648[nm].

Stroke is a leading cause of death in Korea. Although the most cost-effective treatment is primary prevention, appropriate managements are influenced on mortality or disability during acute period after onset. Stroke is a vascular event secondary to real disease of blood vessels of the brain. Also, stroke is not one illness but rather it includes several diseases that lead to occlusion of a vessel and progression of neurologic symptoms. Neurologist or physicians must decide treatment options according to medical problems of individual patient. In this review, the process of diagnosis and the principles of evidence based management of patients with acute stroke were described.

We report a case of acquired hemophilia A following endoscopic sinus surgery. The patient was a 64-year-old man whose preoperative activated partial thromboplastin time (aPTT) was slightly prolonged. He underwent endoscopic sinus surgery for chronic rhinosinusitis with nasal polyp. Nasal bleeding occurred spontaneously on the postoperative day 3. The aPTT was prolonged at 58.9 s, with factor VIII activity of 21% and a positive factor VIII inhibitor. Treatment with factor VIII and methylprednisolone resulted in remission within 1 month. This is the first of such case reported in Korea; the patient was treated by recombinant factor VIII replacement and steroid therapy.

초등학교 생존수영교육 매뉴얼의 문제점 및 개선방안

안성환 한국스포츠학회 2020 한국스포츠학회지 Vol.18 No.2

본 연구는 2019년 07월 26일에 교육부가 홈페이지를 통하여 게재한 초등학교 생존수영교육 매뉴얼을 분석하고 문제점과 개선방안을 제시하는데 목적이 있다. 본 연구에서는 수영 활동의 가장 기본이 되는 호흡하기, 뜨기, 나아가기의 과정을 생존수영 초급단계의 필수과정으로 제안하고, 교육 장소에 따라 물 밖, 풀 사이드, 물속으로 구분하여 수행방법을 제시하였다. 호흡하기는 물 밖에서 기본 호흡 1, 2단계와 응용호흡을 연습하고, 이후 풀 사이드를 잡거나 걸어가면서 낮은 물 호흡하기와 깊은 물 호흡하기의 연습을 한다. 뜨기는 물 밖에서 바닥에 누워, 누워 뜨기를 단계별로 연습하고 이후 풀 사이드에 발뒤꿈치를 걸고 누워 뜨기를 하여, 숙달되면 몸속에서 맨몸 누워 뜨기를 한다. 나아가기는 물 밖에서와 풀 사이드에서 발차기와 기본 배영 팔 돌리기를 연습하고, 물속에서 맨몸으로 기본 배영을 연습한다. The purpose of this study is to analyze the survival swimming education manual of elementary which is the Ministry of Education posted on its website on July 26, 2019, and to suggest the problems and improvement measures of it. In this study, it was proposed breathing, floating, and moving forward, which is the most basic processes of swimming activities as an essential courses in beginning level of the survival swimming, and to suggest the training method by dividing them into out of water, poolside and in the water depending on educational site. In breathing, it practices basic breathing steps 1 and 2 and applied breathing outside of the water, and then practice breathing in shallow water and breathing in deep water while griping poolside and walking. In floating, you practice step by step floating and lying down on the floor outside the water and back floating while putting one’s heels on the poolside, and practice full floating when it being skillful. In moving, it practices kicking and arm stroking of basic backstroke outside the water and in the poolside, and practices basic backstroke in the water.

교수활동이 지닌 평생교육 및 인격교육적 속성: 수영교수의 학교, 가정, 사회에서의 교육활동을 중심으로

안성환 한국인격교육학회 2010 인격교육 Vol.4 No.2

Education is made up of teaching and learning. Educational achievement depends largely on teaching activities. In order to gain educational achievement, teaching activities should be educational. However, there have been upward trends for teachers to perform their teaching activities like employers at a company do work. In this regard, we say that there have disappeared true education between teacher and student. With Korean schools facing this educational situation, this paper analyzes ‘swimming teaching’ as a practical case and discusses the attributes of its lifelong education and saramdaum education. The results tell that teaching activities are not limited just to the domain of regular teaching time and the contents of official curriculum. Also, teaching activities are not limited to teaching class; in addition to the teaching class, they are desirable to be performed in a lifelong-educational way, at home and school, and in society. Also the contents should not be limited to regular subjects. They are desirable to be expanded to other contents rather than those of regular subjects and even to saramdaum education. Therefore, this paper casts light on the fact that teaching activities involve the attitudes of lifelong education and saramdaum education, and that these attitudes should be actively realized and reflected in teaching activities so as to attain more educational achievement. The teaching activities themselves should be performed in a lifelong-educational manner, and at the same time they need to go side by side with saramdaum education. 교육은 교수와 학습으로 이루어지고, 교육의 성과는 교수 활동에 의존하는 바가 크다. 교육이 소기의 성과를 거두기 위해선 교수 활동이 교육답게 이루어져야 한다. 그렇지만 교사들이 교수활동을 사기업의 회사원처럼 교직 환경에서 부과된 직무에만 한정하려는 경향이 늘고 있다. 이러한 교육현실에 직면하여, 본고에서는 교수활동의 실천 사례로서 현직 수영교수의 교육활동을 분석하여, 그 평생교육 및 인격교육적 속성을 논의하였다. 본고의 연구결과에 따르면, 교수활동은 한정된 수업 시간과 교과목 내용에 국한된 것이라 할 수 없다. 교수활동은 학교의 정규수업에만 한정된 것이 아니라, 정규수업 이외의 학교 활동과 가정 및 사회에서도 평생교육적으로 일어나는 것이다. 또한 그 내용은 정규 교과목 내용에만 한정된 것이 아니라, 학생들을 올바르게 가르치기 위해선 필요에 따라 정규 교과목 이외의 내용은 물론이거니와 인격교육 내용으로도 전개되어야 함을 파악할 수 있었다. 따라서 본고에서는 교수활동이 평생교육 및 인격교육적 속성을 지니고 있으며, 이러한 평생교육 및 인격교육적 속성이 교수활동에서 적극적으로 잘 발휘되어야 교육이 소기의 성과를 거둘 수 있음을 제시하였다. 각각의 교과목에서 가르치는 내용이 모두 동일한 것은 아니지만, 모든 교수활동은 그 자체가 평생교육적으로 수행되어야 하며, 이와 동시에 인격교육을 병행할 필요가 있음을 이해할 필요가 있다.

Warfarin is widely used for the prevention of cerebral infarction, especially in patients with atrial fibrillation or artificial valve. Although hemorrhagic problems are well known, skin necrosis is a rare complication. Failures of early diagnosis or management may lead to serious results. We report a case of skin necrosis induced by warfarin therapy.

안성환 한국스포츠학회 2019 한국스포츠학회지 Vol.17 No.4

The purpose of this study is to analyze the standard course of survival swimming in elementary schools announced by the Ministry of Education in 2017 and to suggest issues and improvement plans. In this study, the survival swimming curriculum is divided into the required course and elective course in order to improve the standard course for elementary schools and it suggested that the breathing is comfortable breathing, the floating is back float, and the moving is backstroke. It is necessary to develop play activities applying required courses to an elective courses and it should be developed the training programs for current and preservice teachers as well as the continuous and efficient manuals and systematic dissemination at the Ministry of Education level. It need to provide an institutional preparation that teachers can learn survival swimming and participate in its education initiatively through the program. 본 연구는 2017년도에 교육부에서 발표된 초등학교 생존수영 표준과정을 분석하고 문제점과 개선방안을 제시하는데 목적이 있다. 초등학교 생존수영교육 표준교육과정의 개선 방향으로 생존수영 교육과정을 필수 과정과 선택과정으로 나누고, 필수과정에서 호흡하기는 편안한 호흡을, 뜨기는 배면 뜨기를, 이동하기는 기본 배영을 제안하였다. 그리고 선택과정으로 필수과정을 응용한 놀이 활동의 개발이 필요하며, 교육부 차원에서 지속적이며 효율적인 매뉴얼 개발과 체계적인 보급과 더불어 현직교사와 직전교사들의 직무연수 프로그램을 통하여 생존수영을 익혀 교사들이 생존수영 교육에 주도적으로 참여하여 활동할 수 있는 제도적인 마련이 필요하다.

The purpose of this study was to identify the relationships between recognition of instructor image and exercise adherence on swimming participants, In order to achieve this purpose, 500 subjects were selected by the stratified cluster random sampling method among participants of swimming programs . Although 500 participants responded, only 424 were used for data analyses because 76 were considered to be incompletely or incorrectly responded to. The survey questionnaires were 1) the Image Description Questionnaire(IDQ) developed by Dowling(1996) and standardized in the Korean language by Park(2000). The statistical methods utilized in the study for analyzing the collected data were reliability analysis, descriptive statistics, one-way ANOVA, Chi-square test, correlation analysis. and from the results of this study, the following conclusions were drawn: First, recognition of instructor image and exercise adherence are partially different by socio-demographic characteristics. Second, recognition of swimming instructor image effect on exercise adherence.
