Despite many theoretical advantages of humidification of anesthetic gas, the role and method of choice of humidification in anesthesia remains uncertain. With the recent introduction of disposable heat and moisture exchangers (HME), a paueity of information of the specific performance characteristics of various HMEs exists. Using an on-line humidity detector, based on the dry-wet bulb principle, with a fast response temperature sensor (0.l sec), I have reexamined the effectiveness in maintaining humidity and temperature of various commercially available HMEs in clinical settings, and the relationship of the effectiveness of the rate of fresh gas flow. Humid-Vent 2 demonstrated the best result that increased the inspired temperature from 22.78±0.2℃ to 31.35±0.89℃ (absolute humidity; 27.4±0.7mg H2O/L). Extreme low fresh gas flow(500ml/min) demonstrated low absolute humidity (18.87±1.28 mg H2O/L) that was lower than use of HME.

Competition Issues of the Korean Broadcast Service Provision Market in the Multimedia and Multichannel Era

윤석민,김희진 한국학중앙연구원 한국학중앙연구원 2006 Korea Journal Vol.46 No.3

The changes in the Korean broadcast service provision market for thelast few years are summed up as the advancement from a terrestrial to amultichannel TV situation. Terrestrial TV is weakening while cable SOsare experiencing rapid growth. Cable SOs, however, are also facing com-petition. Major over-the-air networks are spinning off PPs centered onentertainment, drama and sports in an effort to diversify their business.The production budgets are relatively focused on commercial content,which in turn are moved to the pay PP channels. In this vein, publicand universal service functions of over-the-air networks are weakening.Pay TV exists as a sub-low market, centered around cable SOs. PPs relyhighly on advertisements while adopting a low-cost programming strate-gy. Satellite TV is suffering from this sub-low market. The rising compe-tition in the broadcast service provision market does not mean thatsociocultural policy matters will fade away. On the contrary, the effortsto link competition in broadcast market to its desirable socioculturaloutcomes should persist.

PURPOSES : The objective of this study is to analyze factors affecting traffic accident severity for determining countermeasures on freeway climbing lanes. METHODS : In this study, an ordered probit model, which is a widely used discrete choice model for categorizing crash severity, was employed. RESULTS : Results suggest that factors affecting traffic accident severity on climbing lanes include speed, drowsy driving, grade of uphill 3%, gender (male offender and male victim), and cloud weather. CONCLUSIONS : Several countermeasures are proposed for improving traffic safety on freeway climbing lanes based on the analysis of crash severity. More extensive analysis with a larger data set and various modeling techniques are required for generalizing the results.

<농가월녕가>에 대한 텍스트언어학적 분석 : 텍스트 단위 설정 문제를 중심으로

윤석민 국어국문학회 2004 국어국문학 Vol.- No.137

This thesis is for the analysis of <Nonggaweollyeongga(농가월녕가)>(=N in followings) by text-linguistic method, specially cohesion and coherence. According to this analysis <N> has the properties as follows : 1) The basic text-unit of <N> are lines and a line is composed of two phrase and each phrase have commonly four syllables. In the case of less-four syllbles phrase there is a long sound in a syllable of it and in the case of over-four syllables phrase there is an ellipsis of syllable(s) in it. 2) Most of sentences of <N> are composed of one line. But there are also sentences formed by over two lines and a few sentences made of 5 or 6 lines. 3) Ending '-ni(니)' occurred in <N> is divided into two kind of ending, one is a linking ending meaning 'cause or reason' and the other is a closing ending which means 'representative' and is formed in 'banmal(반말)' type. Therefore the lines which have the latter '-ni' must be counted as a independent sentence. 4) There are cases in <N> in which a line is composed of two sentences. But because these lines can be rewritten to a sentence, these lines must be counted as just a unit for text-linguistic analysis of this text. There are also cases <N> in which sentence begins or closes in the middle of a line. In these cases, they need to be counted as a separate text unit because they are distinguished semantically and syntactically. 5. The integration structure (15) of the begging song of <N> which is resulted from text-linguistic analysis, specially cohesion and coherence show the structure of 'seasonal divisions of nature and human correspondence to it'. This is the same in all the each month's age songs of <N>

《易纬》的双层思想体系: 神秘宗教性和自然科学性的矛盾与否

윤석민 한국중국학회 2012 國際中國學硏究 Vol.0 No.15

Yiwei is the text of ZhouYi theory in han dynasty. Most of the modern scholars regard it as the repository of ‘Xiangshu’ ZhouYi theory and the numinous text. But there are two different aspects. One is religious words, the other is scientific words. There are for two primary reasons. First, there is the backgrounds of period that the religious theory(the response of nature and man-天人感應) was widespread and the astronomy developed in han dynasty. Second, there is the properties of ZhouYi that are the predicting and the philosophical elements. In regards to Yiwei's research, Most of the modern scholars have concentrated their attentions on the aspect of Xiangshu and numinous thing. There have been very rare to see the work about scientific thing of Yiwei. Analyzing this scientific things of ‘Xiangshu’ inside is the motive for this thesis. From this, this thesis analyze the problem that the numinous thing and the scientific thing is contradicting each other or harmonious in Yiwei and proposed solutions to it. In conclusion, two elements seemed to be contradiction are either the supplementary thing or th necessary thing each other in the concept of changing things in accordance with climate changing(物候). This concept indicates the harmony and supplementation of two elements in the backgrounds of period and the history of Xiangshu ZhouYi theory.

本稿的目的在於通過分析[周易]所揭示的生命活動而得出`由憂患意識自覺生命`道德意識`的結論。 『周易』裏的世界與人間都是生生不息的存在。 人間的存在是模?天地的生成`變化之勢而運動的, 其憂患意識是在?於自己的生命活動背離於天地生成`變化的原理中産生的。 在『周易』看來, 憂患意識是可否做到防患於未然的問題。 此?不單純是一個生命保存的問題, 還是一個德性修養的問題。 將人類包括的宇宙萬物隨著太極·乾坤·陰陽相通, 相生的生命活動而生成變化, 人類通過認識和實踐他們的運動方式, 在一方面保持生命活動, 在?外一方面發揚道德意識。 在此, 憂患意識的自覺成爲認識太極·乾坤·陰陽的運動變化的動力, 憂患意識的顯現就標示由生命自覺向道德修養的起點。 本稿裏, 通過分析`易`, `太極`, `乾坤`, `陰陽`, `易卦與難卦`而論述『周易』的憂患意識當聯結生命和道德的橋梁功能。

식생 침수비를 고려한 파고 감쇠에 관한 실험적 연구

윤석민,장대정 청운대학교 건설환경연구소 2012 청운대학교 건설환경연구소 논문집 Vol.7 No.1

This study was performed to examine the wave attenuation and the beach deformation due to vegetation inundation ratio by hydraulic experiment. The hydraulic experiment was performed by use of 2-D irregular wave tank(L=15m, H=0.6m, W=0.5m). The artificial seaweed was made of polypropylene strip with a specific gravity of 0.95. The experiment results show that the wave attenuation increase in proportion to vegetation inundation ratio. And beach deformation is changed from the erosion to the accretion or intermediate by increasing vegetation inundation ratio. 본 연구는 식생 침수에 따른 파고 감쇠와 해빈변형을 추정하기 위하여 수리 모형실험을 수행하였다. 수리 모형실험은 2차원 불규칙 조파수조를 사용하여 수행하였다(L=15m, H=0.6m, W=0.5m). 인공식생은 비중이 0.95인 폴리 프로필렌으로 제작하였다. 파고 감쇠는 식생 침수비에 비례하여 증가하는 결과를 나타내었고 해빈변형은 식생 침수비가 증가함에 따라 침식에서 퇴적 또는 천이로 변화하였다.
