황우섭 한국방송공사 2003 방송 문화 연구 Vol.15 No.1

This article examines the reason why Korean broadcaster makes inroads into global market and what are the strategic management and programming for international TV broadcasting channel. This study include the following problems: First, how has been transforming the mission of international broadcasting since media environments have changed? Second, how have managed the international broadcasting and what strategies have made use the foreign broadcasters like BBC and NHK? Third, what should be the strategies of the channel management and programming for Korean international TV Broadcasting ‘KBS World’? In progressing media environments and digital technology, the mission of international TV broadcasting has changed. Currently, the main goal of international broadcasting is to enhance the power of national brand for global marketing and making profits with it rather than publicity activities for country. Many foreign broadcaster, especially BBC and NHK have successfully made use of a global network system for globalization of broadcasting. In South Korea, KBS has been working for this by building an international TV broadcasting, KBS World. This is very useful way for the globalization of Korean broadcasting. KBS World will be contributed to the globalization of broadcasting and development of broadcasting industry.

황우섭,정다은 대한신경집중치료학회 2018 대한신경집중치료학회지 Vol.11 No.1

Background: Herpes zoster of the head and neck commonly presents with Ramsay Hunt syndrome. However, vesicular eruptions may occur on the pharyngeal or laryngeal area with multiple lower cranial-nerve (CN) palsy. Case Report: We report on the case of a 54-year-old man with herpes zoster of the pharynx and larynx with multiple CN palsy and persistent hiccups. He initially developed progressive dysphagia, hoarseness, and persistent hiccups (CN IX and X). After admission, Dizziness, hearing impairment, and peripheral facial palsy (CN VII and VIII) were complicated. The results of a polymerase chain reaction test of saliva and vesicular fluid from the ear and throat were strongly positive for varicella zoster virus. The progression of CN palsy was in an ascending sequence. Conclusion: We suggest that the sequence of CN palsy may be either ascending or descending, depending on the initial site of involvement.

송사리과 Swordtail (Xiphophorus hellerii)의 난모세포 성숙과정에 관한 미세구조 연구

황우섭,김완종,류동석,Hwang, Woo-Sub,Kim, Wan-Jong,Reu, Dong-Suck 한국현미경학회 1998 Applied microscopy Vol.28 No.3

Oocyte maturation of the swordtail (Kiphophorus hellerii) was investigated by light and electron microscopy. In the ovary of the swordtail, various staged oocytes were observed, Mature oocytes were located in ovarian cortex, meanwhile immature ones were positioned in ovarian medulla. The oocyte was surrounded by several structures or cells such as chorion, follicle cells, follicular theaca and ovarian epithelium, respectively, from the inside toward outside. Growing and maturing oocytes healed numerous microvilli which interconnected the oocyte and the follicle cells to communicate each other. The mature oocyte had the electron dense chorion which appeared to be ultrastructure of two layers and contained pore canals. Oocyte maturation was characterized by not only the enlarged cell size and well differentiated cell organelles, brit also the increases of fat droplets, pinocytotic vesicles and yolk granules.

A Case Report of Three-Dimensional Fiber Tractography of Anterior Thalamic Radiation in a Capsular Genu Infarction

황우섭,오윤아,장성만,진주희,서미경,서상원 대한치매학회 2010 Dementia and Neurocognitive Disorders Vol.9 No.1

Interruption of the anterior thalamic radiation (ATR) might explain cognitive impairment in an infarction of the genu of the internal capsule. However, a defect of the ATR in the genu infarction has received little attention. We report on a patient who developed cognitive impairment following the genu infarction. Diffusion tensor imaging revealed an interruption of the white matter fibers in the ATR. We suggested that cognitive impairments in the genu infarction were caused by a defect in the ATR.

Hashimoto’s Encephalopathy with Reversible Diffuse Leukoencephalopathy

황우섭,정다은 대한신경집중치료학회 2018 대한신경집중치료학회지 Vol.11 No.1

Background: The magnetic resonance imaging (MRI) findings of Hashimoto's encephalopathy (HE) are variable; images range from having a normal appearance, to showing ischemic lesions, demyelination, or vasogenic edema. Case Report: A 57-year-old woman presented with a sudden onset of dysarthria and dizziness. Routine blood tests were normal and the MRI was unremarkable. After admission, she developed aphasic seizures and myoclonus, and eventually became comatose. A follow up MRI showed diffuse high signal intensities at the bilateral cerebral white matter on fluid attenuated inversion recovery imaging. The serum titers of the anti-thyroglobulin antibody and anti-thyroperoxidase antibody were increased. After 5 days of 1,000 mg/day of intravenous methylprednisolone infusion, she recovered rapidly. Conclusion: We propose that repeated brain MRIs are necessary for the diagnosis of HE. Diffuse leukoencephalopathy may be a pathologic finding on MRI and, in this case study, was shown to be reversible after applying an appropriate treatment.

삼킴장애를 보이는 뇌졸중환자의 침습 및 흡인에 따른 설골 이동범위 특성

황우섭(Wooseop Hwang),하승희(Seunghee Ha),황수진(Sujin Hwang) 한국언어청각임상학회 2011 Communication Sciences and Disorders Vol.16 No.3

배경 및 목적: 설골의 이동 범위는 후두덮개의 이동, 후두의 상승, 그리고 반지인두근의 열림에 영향을 미치며 흡인을 예측하기 위한 중요한 지표로 보고되고 있다. 현재까지 많은 선행연구에서 설골의 전방 이동, 상승 이동, 전방-상승이동으로 다양한 설골의 이동범위를 보고하였다. 본 연구는 현재까지 보고되고 있는 세 가지 정량화된 측정방법을 가지고 삼킴 장애를 보이는 뇌졸중 환자들을 대상으로 정상 삼킴, 침습, 흡인 삼킴에 따라 설골의 이동범위가 차이를 나타내는지를 살펴보고자 하였다. 또한 어떠한 측정 방법이 삼킴 유형에 따른 차이를 가장 잘 설명할 수 있는지를 살펴보았다. 방법: 연구대상은 삼킴 장애를 보이는 뇌졸중환자 30명을 대상으로 5cc액체를 2회씩 평가하였다. 그러나 첫 번째 삼킴에 흡인을 보였을 경우 안정상의 이유로 1회만 평가하도록 하였다. 각 대상자에게서 얻어진 총 삼킴 횟수는 58개이며 각 삼킴은 정상 삼킴 25개, 침습 18개, 흡인 15개의 삼킴 유형으로 평가되었다. 침습 및 흡인의 시기는 설골의 이동과 연관을 짓기 위해 삼킴 도중 및 삼킴 후로 제한하였다. 설골의 이동패턴을 고려하여 (1) 최대 전방 이동범위, (2) 최대 상승 이동범위, (3) 최대 전방-상승 이동범위를 측정하였다. 결과: 설골의 최대 전방 이동범위와 최대 상승 이동범위는 삼킴 유형 간(정상 삼킴, 침습, 흡인) 차이를 보이지 않았다. 그러나 설골의 최대 전방-상승이동범위는 정상 삼킴이 흡인 시 보다 큰 설골의 이동범위를 보였다. 논의 및 결론: 본 연구결과는 설골의 움직임 범위가 작을수록 흡인이 일어날 확률이 높음을 지지하고 있다. 또한 설골의 최대 전방 이동범위와 최대 상승이동범위를 각각 측정하는 것 보다 전방과 상승이동을 동시에 나타내는 설골의 최대 전방-상승이동범위를 측정하는 것이 흡인을 예견할 수 있는 지표로 보다 적절함을 제안하였다. 또한 설골 이동범위의 정량화된 측정은 환자의 치료 전과 후를 비교할 때에도 객관적인 정보를 제공할 수 있을 것임을 제안하고 있다. Background & Objectives: Displacement of the hyoid bone is important for predicting aspiration as it influences epiglottic inversion, laryngeal elevation, and cricopharyngeal muscle opening. The purpose of this study was to investigate whether there are differences in the displacement of the hyoid bone among normal, aspirated, and penetrated swallows in post-stroke patients with dysphagia using an objective and quantitative assessment method. Also, the study aimed to explore which quantitative measures best explained the differences among normal, aspirated, and penetrated swallows. Methods: Thirty post-stroke patients showing dysphagia received videofluoroscopic swallow assessment. Subjects performed two swallows of a 5cc bolus of liquid barium. Subjects who showed aspiration during the first swallow did not proceed to the next swallow for safety reasons. Fifty-eight swallows from 30 patients were divided into 25 normal swallows (non-penetration and aspiration), 15 aspirations, and 18 penetrations. Three measurements reflecting the movement patterns of the hyoid bone, (1) maximum anterior displacement of hyoid bone, (2) maximum superior displacement, and (3) maximum anterior-superior displacement, were obtained. Results: Maximum anterior displacement and maximum superior displacement of the hyoid bone did not show significant differences among the three types (penetration, aspiration, non-penetration and aspiration). However, maximum anterior-superior displacement in non-penetration and aspiration was significantly larger than that in aspiration. Discussion & Conclusions: The results of this study support the finding that the limited displacement of the hyoid bone increases the risk of aspiration during and after swallows. This study also suggests that maximum anterior-superior displacement, which reflects simultaneous anterior and superior displacement of the hyoid bone, might be a more appropriate predictor of aspiration. In addition, this study suggests that the quantitative measurement of the displacement of hyoid bone can be used to objectively evaluate patients’ swallowing abilities and the effectiveness of treatments.

인터넷의 발전으로 웹 서비스를 사용하는 사용자가 기하급수적으로 늘어났고 사용자에게 다양한 서비스를 제공하기 위해 많은 기술이 등장하고 있다. 서비스를 받는 사용자의 웹브라우저에서도 서버의 많은 기술을 구현할 수 있는 공간을 제공하고 있는데 바로 Web Storage와 Indexed DB이다. Web Storage는 용도에 따라 수 MB 정도를 사용하지만 많은 양의 데이터를 구조화하여 사용한다면 Indexed DB가 적합하다. 하지만 Web Storage뿐만 아니라 Indexed DB 역시 영속적이고 평문의 데이터를 저장하고 있다. 이러한 데이터는 웹 보안에 취약하여 XSS 등의 공격에 사용자의 데이터가 노출되어 탈취되거나 편집되어 악용될 우려가 매우 크다. 본 논문에서는 이와 같은 취약점을 보완하기 위해 운영체제와 디바이스 정보를 이용하여 사용자를 인증하고 암호화하는 기법을 구현하여 성능 평가를 하였다.
