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].

This presents the method of large area analysis with laser process for the temperature distribution predicts of workpiece by using ANSYS Workbench, the commercial finite-element analysis software. From the method, It is possible to carried out that impossible analysis by past method because problems of great dimensions Following the results, we can expect that easily predicts temperature distribution of laser processed area. it can utilize on various purpose that thermal displacement, stress and etc.

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.

Background:Arteriovenous malformations (AVMs) with vascular abnormalities, including aneurysms, have been reported frequently. However, the coexistence of AVM and unilateral moyamoya disease is rare. We report herein an AVM patient who presented with acute ischemic stroke with unilateral moyamoya disease and occlusion of the feeding artery. Case Report:A-41-year old man was admitted with sudden dysarthria and facial palsy. Brain computed tomography and magnetic resonance imaging revealed an acute infarction adjacent to a large AVM in the right frontal lobe. Cerebral angiography revealed occlusions of the proximal right middle cerebral and proximal anterior cerebral arteries, which were the main feeders of the AVM. Innumerable telangiectatic moyamoya-type vessels between branches of the anterior cerebral artery and dilated lenticulostriate arteries on the occluded middle cerebral artery were detected. However,a nidus of the AVM was still opacified through the distal right callosomarginal artery, which was supplied by the remaining anterior cerebral artery and leptomeningeal collaterals from the posterior cerebral artery. Conclusions:While AVM accompanied by unilateral moyamoya disease is rare, our case suggests an association between these two dissimilar vascular diseases.

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.

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.

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.
