Many techniques have been tried to avoid the adverse effect of succinylcholine administered for endotracheal intubation especially wish the complication of increased IOP, hyperkalemia, aspirationl pneumonia and post·operative muscle pain. One of these is that the prior administration of a small, subparalyzing dose(15 ㎍/kg) of non-depolarizing muscle relaxant would shorten the onset time of an intubating dose(80 ㎍/kg) of muscle relaxant. Intra-venous lidocaine has bean effective in attenuating the reflex intra-ocular response to laryngoscopy Therefore, we determined the effectiveness of this drug regimen with and without intra venous lidocaine to attenuate the IOP, blood pressure and heart rate response to laryngos-copy and endotracheal intubation. Forty patients were divided intro two groups. Group I (n=20) administered saline 5 ml. Group Ⅱ(n=70) administered 2% preservative free lidocaine(1.5 mg/kg) as pretreatment drug. The results are as follows : 1) There was no statistically significant difference intubation condition between one and another group. Among the forer patients, Grade 1,2,3,4 are 8(20%), 19(47.5%), 13(32.5%),0, in orders. 2) In the Saline Group, IOP, BP, HR increased significantly after laryngoscopy compared wiith control value. (p$lt;0.001, P$lt;0.05/p$lt;0,001, p$lt;0.005) and maintained above control values to 4∼5 minutes later. 3) In the Lidocaine Group, IOP, BP, HR increased slightly after laryngoscopy compared with control value, but thege changes were not statistically significant, and decreased below control values in 2 min, 2min, 3 min after laryngoscopy each to each. From the above results, it is suggested that combined method of pretreatment of 2% lidofaine(1.5 mg/tg) and divided dose of pancuronium is valuable in general anesthesia of ophthalmic patient who need to attenuate the IOP.

경제성장에 있어서 대학교육의 영향

김선재 한국콘텐츠학회 2019 한국콘텐츠학회논문지 Vol.19 No.2

The purpose of this study is to reanalyze the impact of college education in the Korean economic growth during the period 1971-2017. The study estimates the impacts of monthly average income per worker without college education with respects to the ratio of workers with college education to worker without college education, capital per worker without college education, and the number of patients per worker with college education. The results showed that the effect of the ratio of workers who had college education was 0.433 at 5% of significant level. In addition, it was estimated that the effect of the capital for each worker who didn’t have college education was 0.45646 at 1% of significant level. These findings are similar to the results in the previous study of Kim and Lim. Finally, the number of patents per worker who had college education was estimated. Unfortunately, the coefficients on these were not statistically significant except for one period. Therefore, it is concluded that there is a positive spillover effect from the college education in the Korean economic growth. 본 연구는 한국에서의 대학교육이 경제 사회적 수익성 관점에서 얼마나 많은 긍정적인 파급효과를 가지고 있는지를 1971-2017년 기간의 자료를 이용하여 분석하였다. 첫 번째로 대졸자 수와 비대졸자수 비율 즉 비대졸자수 1인당 대졸자 수가 비대졸자의 월평균임금에 미치는 형향을 추정하였다. 추정된 계수는 0.433으로 95%의 신뢰수준에서 통계적으로 유의미한 결과를 보였다. 이 같은 결과는 대학교육이 비대졸 출신자들의 소득을 증대시켜 간접적으로 국민경제에 긍정적인 파급효과를 미치고 있음을 보여준다고 하겠다. 두 번째로 비대졸자 1인당 자본량이 월평균임금에 미치는 영향을 분석하였다. 계수는 0.45646으로 약 99%의 신뢰수준에서 통계적 유의성을 보이고 있음에 따라 1%의 비대졸자 1인당 자본량 증가는 비대졸자 1인당 월평균임금은 약 0.45646% 증가시키는 것으로 나타났다. 따라서 본 연구 결과는 선행연구와 유사하게 지난 40여 년간 한국에서의 대학교육은 국민경제에 긍정적인 파급효과를 준 것으로 보여진다. 끝으로 또 다른 파급효과를 추정하기 위하여 대졸 1인당 특허등록수를 독립변수로 추가하였으나 한 기간 외는 통계적으로 유의성이 증명되지 못하였다.

울프의 『파도』 속 사물의 신비

김선재 한국영어영문학회 2020 영어 영문학 Vol.66 No.2

Virginia Woolf’s conceptualization of life as “a luminous halo, a semi-transparent envelope surrounding us from the beginning of consciousness to the end” in her essay entitled “Modern Fiction” published in 1919 demonstrates her deep interest in an inseparable relation between human consciousness and things such as an envelope. However, although critics have noted with increasing urgency how Woolf formulates objects and things in relation with language and subjects in her works, there have been relatively few studies on Woolf’s exploration and representation of things in her full-length novels. Literary critics as eminent as Bill Brown and Douglas Mao have particularly focused on how Woolf’s short story entitled “Solid Objects” represents a new sensation of things by focalizing a man’s weird attachment to useless objects. While drawing on some of the significant arguments made by the critics who analyzed Woolf’s insight into things in the short story, this article mainly concerns Woolf’s thoughts about things in The Waves. This article’s central claim is that the mystery of things represented in The Waves lies in their paradoxical existence inside and outside of language at the same time. The mystery of things, I hope to show in this article, urges one to escape the dangerous confinement of narcissistic self, which can lead towards an imperialistic and totalitarian drive to subjugate disparate beings and things. The article also hopes to kindle an interest in Woolf’s reconceptualization of modernism’s public world as a place to radically rethink one’s relation with things.

In this study , short -circuit processes were analyzed via simulations and experiments by applying a principle that caninterpret the short-circuit marks, which are the most basic inspection criteria in fire-scene investigation. According toFleming's left-hand rule, a Lorentz force is generated when current and magnetic fields are applied. Railgun, one of thetypical applications, utilizes the same basic principle for generating trajectories. Using the same concept, it was interpretedthat the molten copper balls generated during a short-circuit process scatter in the load direction similar to a ballistic launch. The simulation and experimental results also confirmed that the copper balls were scattered in the load direction owing tothe Lorentz force. Although it is impossible to examine the source and load during a fire-scene investigation process, thestudy findings will aid in predicting the load by observing the portion where the copper bulbs are relatively frequent. Thus,based on an estimation of the cause of fire, it will be possible to infer reliable results through fire-scene investigation. 본 논문에서는 화재 현장 조사에서 가장 기본으로 검사하는 단락흔을 중심으로 단락 과정을 해석할 수 있는 법칙과 원리를 적용하여 시뮬레이션과 실험으로 분석하였다. 플레밍의 왼손 법칙에서 전류와 자기장이 작용할 경우, 로렌츠의 힘이 발생하게 된다. 이를 응용한 것이 레일 건으로써, 탄도가 발생되는 원리를 적용하였다. 이를 통해 탄도발사와 동일한 형태로, 단락 과정에서 발생되는 용융된 구리 망울이 부하측 방향으로 비산되는 것으로 해석하였다. 시뮬레이션 및 실험 결과에서도 로렌츠의 힘에 의해 구리 망울이 부하측 방향으로 비산되는 것을 확인하였다. 화재조사 과정에서 전원측과 부하측에 관한 검토가 불가능 하더라도, 연구를 통해 얻어진 결론을 적용하여 구리 망울이상대적으로 많이 형성된 부분을 부하측으로 예측할 수 있을 것이다. 이를 통해 발화원인을 추정할 수 있는 근거를마련할 수 있기 때문에 화재 조사의 신뢰성 있는 결과를 추론할 수 있을 것이다.

現代英語 前置詞的副詞 ‘down'의 敍述動詞 補文 硏究

金善再 慶熙大學校 1980 論文集 Vol.10 No.-

Among many constructions, a keen interest and enthusiasum are given to the particular structure of Verb + down (+ Prepositional Adverb_2)in contemporary English. Findings of present research, three major types of structure which convey menning in different process. The model of the construction is whown as below: Verb + down(+ Prepositional Adverb_2) Under Type One, two meanings of its constituents are expressed simeltenously: Verb expresses its own lexical meaning as well as the complement 'down' of its own lexical meaning. Under Type Two, the lexical meaning of Verb is thoroughly expressed whereas the meaning of 'down' is not expressed, serving as an intensitying function. Under Type Three, neither of lexical meaning of Verb nor down (including an additional Prepositional Adverb, if any). An entirely new meaning - idiomatic meaning is given. A brief historical survey is given on the Prepositional Adverbs and their constructions. Many collected examples are shown for the purpose of demonstrating the structural justification for three major types in contemporary English.

現代英語의 Collocation에 關한 硏究 : 名詞, 形容詞, 副詞+前置詞 /副詞를 中心으로

金善再 연세대학교 대학원 1963 延世論叢 Vol.2 No.1

In recent years there has been a growth of interest in the study of word sequences which, in traditional terminology are particles preceded by noun, adjective or adverb. This may be illustrated as follows : preposition + word1 The extention of the sequence may be word2 + preposition + words The principle of this study is based on grammatical sequences which have a tie between the x element (word2 : noun, adjective or adverb) and the y element (preposition or adverb). The occurrence of collocation is solely dependent on the environment and the position of x + y The method of this study is a) To collect examples of collocation form recently published novels in the United Kingdom and the United States, b) To classify them according to categories. The first step for this study was to collect examples extensively. In order to analyze the collcation between the r element and the y element, two systems of analysis were applied. 1) Immediate Constituent analysis 2) Bracket analysis 3,320 examples of 26 particles were collected by the writer (See Table I) Following are the results of this study : i. Selected examples of collocation are given in Section IV. ii. A list of high frequency collocations is given in Table II. iii. In Table III, collocations of Noun/adjective + Particle are shown iv. There is a list of collocations of non-Noun/non-Adjective + Particle in Table IV. v. A list open class form collocations is given in Table V. vi. A list of closed class form collocations is shown in Table IV. vii. Lexical variations in collocations are shown in Table VII. xiii. finally a tabular summary for the whole study is given in alphabetical order.

Broadband Phase-change Metagrating Design for Efficient Active Reflection Steering

김선재 한국광학회 2021 Current Optics and Photonics Vol.5 No.2

In this paper, I introduce a novel design method of a high performance nanophotonic beam deflector providing broadband operation, large active tunability, and signal efficiency, simultaneously. By combining thermo-optically tunable vanadium dioxide nano-ridges and a metallic mirror, reconfigurable local optical phase of reflected diffraction beams can be engineered in a desired manner over broad bandwidth. The active metagrating deflectors are systematically designed for tunable deflection of reflection beams according to the thermal phase-change of vanadium dioxide nano-ridges. Moreover, by multiplexing the phase-change supercells, a robust design of actively tunable beam splitter is also verified numerically. It is expected that the proposed intuitive and simple design method would contribute to development of next-generation optical interconnects and spatial light modulators with high performances. The author also envisions that this study would be fruitful for modern holographic displays and three-dimensional depth sensing technologies.

노인의 성공적인 노화를 위한 휴대폰 사용자 경험 : 자원 상황에 따른 가능한 자기 이론과 선택∙최적화∙보상 전략 이론을 바탕으로

김선재,양윤석,이규원,최주희,김진우 한국경영정보학회 2010 한국경영정보학회 학술대회논문집 Vol.2010 No.1

노인들의 연령이 증가함에 따라 신체적·인지적 능력이 저하되는 상황에서도 휴대폰은 가족을 포함한 타인들과 계속 소통하고 다양한 활동에 참여하는 것을 가능하게 한다. 따라서 휴대폰은 성공적인 노화에 있어 유용한 하나의 도구로써 작용할 수 있다. 그러나 현재의 휴대폰은 신체적, 사회적, 심리적 웰빙에 도달하고자 하는 노인의 욕구를 충분히 지원해 주지 못하고 있으며, 노인들은 여전히 휴대폰 사용에 있어 어려움을 표하고 있다. 이러한 배경에서 본 연구는 노인의 성공적인 노화를 지원하기 위한 휴대폰의 사용자 경험 요인이 무엇인지 알아보고, 실제로 노인의 가용 자원 상황에 따라 어떠한 사용자 경험 요인이 강조되는지 알아보려 하였다. 이를 위해 본 연구는 가능한 자기 (Possible Selves) 이론과 선택·최적화·보상 전략 (Selection, Optimization, and Compensation) 이론에 대한 문헌 조사와 정성적 조사를 바탕으로 노인의 휴대폰 사용자 경험에 관한 이론적 모형을 개발하고, 이를 설문 조사를 통해 검증하였다 (N = 182). 그 결과, 품격 (Dignity)과 새로운 기기 사용에 대한 혁신 저항감 (Image Resistance)이 노인의 휴대폰 사용 경험에 있어 영향을 미치는 주요 핵심 요인임을 알수 있었다. 또한 개인의 인지하는 가용 자원에 따라 자원이 적을 경우 품격을 중시하는 휴대폰 개발이 필요하며, 자원이 많을 경우 혁신 저항감을 줄이는 휴대폰을 개발하는 것이 노인의 성공적인 노화에 도움이 됨을 알수 있었다.
