Correlation between Respiratory Rates and the Degree of Bradycardia in Strabismus Surgery in Children Jong-Man Kang, M.D., Hee-Soo Kim, M.D., Chong0Sung Kim, M.D. and Myung-Kul Yum, M.D.^* Department of Anesthesiology, College of Medicine, Seoul National University, Seoul, and ^*Department of Pediatrics, College of Medicine, Hanyang University, Seoul, Korea Background: Strabismus surgery is frequent in pediatric ophthalmic surgery. Traction on the extra-ocular muscles can trigger an oculocardiac rdflex. We investigated the correlation between respiratoy rates and the degree of bradycardia to find another management for preventing oculocardiac reflex. Methods: NO premedications were administered. They were induced with thiopental and vecuronium and maintained with O_@-enflurane-N_2O. The tidal volume was 10 ml/kg. Respiratory rate of group 1 (n = 18) was fixed at 24 bpm, group 2 (n = 18) at 20 bpm, and group 3 (n = 19) at 16 bpm. We measured the mean heart rate from intubation to the beginning of surgery and defined this as the basal heart rate. We defined the lowest heart rate after traction of the extraocular muscles as the minimal heart rate. We calculated the correlation coefficient between the respiratory rate and basal heart rate, minimal heart rate, the change of heart rates and E_tCO_2. Results: There was a positive correlation between the respiratory rate and the basal heart rate, and minimal heart rate. There was no correlation between the respiratory rate and the change of heart rate. There was no difference in E_tCo_2 among the 3 groups. Conclusions: Can be increased both basal heart rate in anesthetized patients and minimal heart rate induced by oculocardiac reflex by making the respiratory rate more rapid if there is no significant difference of E_tCO_2. The oculocardiac reflex may be reduced by making respiratory rate more rapid if there is no significant influence on minute ventilation. (Korean J Anesthesiol 2001; 41: 450~454)

In this paper, the streaming electrification generated at a solid-liquid interface is studied. Electrification pipe modeled on the oil path of the high power transformer is designed and manufactured. The Streaming current is measured as a function of oil velosity, temperature at each electrification pipe. From the result of this study the following conclusions are obtained. 1) The streaming current increases linearly with increasing of oil velocity and It increases at lower temperature than 46[℃]and decreases at higher temperature than 46[℃] 2) The smoother the flow of insulating oil is the less the streaming current decreases.

在日 朝鮮人 姜桂重의 삶과 鬪爭

鄭熙鐥,金仁德 順天靑巖大學 2001 論文集-順天靑巖大學 Vol.25 No.-

HoSan, KangKyeJung was born on August 15, which is Korean Independence Day. He was an actionist to spend his life for the fraters and his country so that had been reached to a fraternity and a patriotism. As a Korean in Japan or Korean-Japanese in Korea, he stood without a peer. Ahead of time, he learned about a strong racial consciousness from his uncle, KangJinWon who was a chief of a righteous army. KangKyeJung fought as a leader of thousands armed Korean workers in SungJin factory against a discrimination and a mistreatment by Japanese. But also KangKyeJung worked for the Korean workers who were drafted from Hotkaido and were trodden down to rescue them. He worked for organizations and the fraters precedently than his private. He had never gave up for any business about the Korean Residents Union in Japan with any hard situation. After the war Korean-Japanese organizations were succeeded as one was JaeilbonChoseoninYeonmageng(在日本朝鮮人聯盟) - JaeilbonChoseonTongil Minjujeonseon(在日朝鮮統一民主戰線)-JaeilbonChoseoninChongyeonhabhoe(在日本朝鮮人總聯合會), the otherhand was ChoseonGeongugchogjinCheongnyeonDongmaeng(朝鮮建國促進靑年同盟) -JaeilbonChoseonGeoryunmindan(在日本朝鮮居留民團) - JaeilbonDaehanmingug Georyunmindan (在日本大韓民國居留民團) - The Korean Residents Union in Japan(在日本大韓民國民團) and some of the parts was succeeded IibonGongsandang Choseoninbu(日本共産黨朝鮮人部) -GogugBangwiwiwondhoe(祖國防衛委員會)- Gogug Bangwidae(祖國防衛隊), Undoubtedly, there were naturally prerequisited human interchanges between organizations. As roling a leader of The Koran Residents Union in Oosaka. He nomalized the Koran Residents Union and also organized the Korean Walfare Association that could be a role to solve the problems of fraters' mutual aid and union hall's registration. Also he had never stopped to support a material help to Korea in depression. Some of days KangKyeJung changed to a business man without any fund, he tried his new life only with his new ideas. He started from a rubber factory and had a hand in an organic business. He made prosperous his business with faithfulness, diligence and reliance that could be a basement of his recovery. KangKyeJung returned to Korea on August, 1957 just 20 years later and he made his mind to settle down in Korea permanently in 1981. KangKyeJung made every effort for Korean-Japanese and Korea, he was only who had limitations about a time and a spirit.

대학 글쓰기 교육의 목표 설정과 지식 정보화 시대의 대응

정희모 이화어문학회 : 이화여자대학교 한국어문학연구소. 2015 이화어문논집 Vol.36 No.-

이 논문에서는 우선 대학 글쓰기 교육의 목표가 무엇인가를 탐색하고 있다. 대학 글쓰기 교육의 목표는 일차적으로 신입생 글쓰기 교육을 통해 전공 글쓰기에 도움이 되고자 하는 것이다. 미국과 한국의 여러 대학들도 학생들이 대학의 학술 텍스트를 잘 쓰기 위해 대학. 글쓰기 교육을 도입하였다. 이런 측면에서 보면 대학 글쓰기 교육의 주된 목표는 학술적 글쓰기 교육이라고 말할 수 있을 것이다. 반면에 이와 다른 관점에서 대학 글쓰기 교육을 바라보는 관점도 있다. 그것은 표현주의 입장으로, 글쓰기를 통해 개인의 자기 탐색, 자기 성찰을 중요하게 생각하는 관점이다. 한국에서 표현주의의 입장은 학술적 글쓰기와의 결합을 통해 개인적 관점과 사회적 관점의 조합을 추구하고 있다. 세 번째로 대학 글쓰기 교육을 인문학적 사고의 학습으로 보는 관점이 있다. 외국어 교육과 다르게 자국어 대학 글쓰기 교육은 다양한 고전의 학습과 함께 인문학적 사고와 성철을 수반하기 때문에 인문학적 교육으로 보아야 한다는 것이다. 대학 글쓰기 교육에서 이렇게 다른 세 가지 관점은 서로 상이한 철학을 지니지만 서로 혼용되어 사용될 수도 있다. 국내 대학들은 대체로 이 세 가지 관점을 섞어서 많이 사용하고 있으며, 학생들의 학술적 쓰기 능력과 자기 성찰, 사회적 비판의식 모두들 소중하게 생각한다. 이보다 대학 글쓰기 교육에서 더 중요하게 바라보아야 할 관점은 지식 정보화 시대에 디지털 글쓰기의 도전과 대응이다. 디지털 시대의 글쓰기는 쓰기 주체의 문제, 소통의 문제, 쓰기 교육의 문제를 다시 돌아보게 한다. 디지털 시대 대학 글쓰기는 매체나 도구의 다양성에도 불구하고 여전히 학생들의 쓰기 능력을 향상시키는 데 중점을 두어야 한다. 아울러 학생들이 자신의 관점을 되돌아보고, 인문학적 자기 성찰을 할 수 있도록 도와주는 것도 중요하다. This article inquires into what the principal purpose of College Writing Education is. Many universities newly instituted College Writing Education for students to improve in their scholarship texts. From this perspective, it can be considered that College Writing Education’s main genre is Academic Writing. However, contrary to the previous perspective, there are also different points of view toward College Writing Education. It is Expressionism in writing. Expressionism’s stance puts importance on individual’s introspection and self-reflection through writing. In Korea, the expressionism’s stance on College Writing Education is that it pursuits a combination of personal perspective and societal perspective joining with Academic Writings. Another angle on the College Writing Education is viewing the writing education as a study of liberal art thinking. This notion is based on the contrary between foreign language education and native writing education that native writing education accompanies liberal art thinking and introspecting with various studies of native classics. College Writing Education’s aim is divided into these three disparate concepts, but these concepts can be used together as well. Universities of Korea mostly combine the three stances and value all their scholarly Academic Writing abilities, Introspection, and Societal criticism. Above all, the perspective that needs to be considered more important in the College Writing Education is preparedness and response toward the information and technology centric society. The digital era’s writing leads us to look back upon the problems within writing subject, communication, and writing education. Despite the divergence of media, digital era’s college writing should place emphasis again on advancement of writing ability, students’ introspection towards their perspectives, and strengthening the insight of humanities.

정현권,변준희,이종원,이종건,임풍,박성찬 大韓成形外科學會 1999 Archives of Plastic Surgery Vol.26 No.3

Cranial fasciitis is a rare morphological variant of nodular fasciitis. It is characterized by a rapid growing fibroblastic proliferative lesion that develops chiefly in childhood. It has varying size and involves the soft tissues of the scalp and the underlying skull. Accurate diagnosis and surgical excision is the key to management. Prognosis is good with rare recurrence. We report a case of cranial fasciitis in the temporal fossa of a 20-month-old girl and present a review of the literature.

정희원,이정일,김종수,오창완,정영섭,장선오,김종선,최길수 대한신경외과학회 1994 Journal of Korean neurosurgical society Vol.23 No.10

The results of a series of thirteen translabyrinthine removals of acoustic neurinomas are reported From 1990 March to 1993 May, thirteen patients with acoustic neummas underwent translabyrinthine removal at Seoul National University Hospital with cooperation of Department of Neurosurgery and Otolaryngology. In four patients with the medium-sized(ll-20mm) tumors, complete removal with preservation of the facial nerve was possible. In nine patients with the large(21-4Omm) tumors, complete removal of the tumor was possible in seven. Preservation of the facial nerve was possible in all but one, whose facial nerve was incidentally transected at the distal intracanalicular portion and was anastomosed end-to-endly. In one, postoperative leakage of cerebrospinal fluid required reoperation. The results of translabyrinthine approaches were compared With those of suboccipital approaches performed during the same period. In medium-sized or large acoustic tumors, translabyrinthine approach was comparable with suboccipital approach in the rate of total tumor removal, preservation of the facial nerves, and complication.

곽종흠,서명석,이태희,곽서연 公州大學校 基礎科學硏究所 2004 自然科學硏究 Vol.11 No.-

본 연구에서는 공주대학교 자연대 옥상에 설치된 분광복사측정기의 일종인 Skyradiometer로 측정된 직달 및 산란 일사량을 이용하여 간접적으로 공주지역의 에어러솔의 광학적 특성을 분석하였다. 분석기간은 2004년 1월부터 11월까지이며 에어러솔의 광학적 특성의 분석에 활용된 알고리즘은 Nakajima et al.(1996)이 개발한 Skyrad.pack.3이다. 주요 분석요소는 에어러솔의 광학두께(AOT), 단일 산란비율(SSA), 옹그스토롬 지수(α) 및 에어러솔의 크기별 분포이며 분석결과의 질을 높이기 위하여 초기 관측 자료의 품질검사를 수행하였다. 공주지역의 11개월 평균 AOT, α 및 SSA는 각가 0.6, 1.1, 그리고 0.9이며 계절 및 기상현상에 따라 큰 시간변동을 보이고 있다. 크기별 입자분포에서는 미세입자와 조대입자에서 최대치가 나타나는 바이 모달 형태를 보이고 있으며 황사(Asian dust) 기간인 봄철에는 조대입자의 총 부피가 크게 증가하였다. 이러한 현상은 봄철동안에 AOT와 SSA가 각각 크게 증가하고 감소하는 점에서도 확인되고 있다. 또한 공주지역의 에어러솔은 풍향에 큰 영향을 받지 않는 것으로 나타나고 있다. We investigate the optical properties of aerosols over Gongju by indirect method using the ground measurement, Skyradiometer. The analysis period is from January to November, 2004. Skyrad.pack.3 is used to estimate the optical properties, such as the aerosol optical thickness(AOT), single scattering albedo(SSA), Angstrom exponent(α) and size distribution, of aerosols from the ground measured radiance data. And quality control process is applied to the raw data to improve the quality of analysis results. The 11-month average of AOT, α and SSA are 0.6, 1.1, and 0.9 respectively. The averaged volume spectra of aerosols show a bi-modal distribution, first peak at fine mode and second peak at coarse mode. Asian dust events clearly increase the AOT and coarse particle, however it decrease the SSA. The effect of wind direction on the optical properties of aerosols over Gonju is not manifest.
