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.

This study identified factors affecting the crash severity at freeway work zones. A nice feature of this study was to take into account the characteristics of work zone traffic management in analyzing traffic safety concerns. In addition to crash records, vehicle detection systems (VDS) data and work zone historical data were used for establishing a dataset to be used for statistical analyses based on an ordered probit model. A total of six safety improvement strategies for freeway work zones, including traffic merging method, guidance information provision, speed management, warning information systems, traffic safety facility, and monitoring of effectiveness for countermeasures, were also proposed. 공사구간에서는 교통류의 안전한 합류 및 통과를 위해 속도관리와 차로차단을 통한 체계적인 교통관리가 요구된다. 본 연구에서는 공사구간 교통관리특성을 교통안전분석에 반영하기 위해서 사고자료, 차량검기지에서 추출된 속도 및 교통자료, 공사 시․종점, 페쇄 차로 등의 정보가 포함된 공사장 이력자료를 활용하였다. 2010년부터 2014년까지 발생한 고속도로 공사구간 사고자료 중 총 231건의 사고에 대해 교통상황자료 및 공사장 이력자료를 매칭시킨 분석 대상 자료셋을 구축하고, 순서형 프로빗 모형을 적용하여 사고 심각도 영향 요인을 도출하였다. 분석결과, 속도, 차로 폐쇄에 따른 용량 감소량, 주의구간 내 사고 위치, 공사 작업 유형의 변수들이 공사구간 사고 심각도에 영향을 미치는 것으로 분석되었다. 분석결과를 바탕으로 6가지 공사구간 안전성 증진 방안을 수립하였다. 안전성 증진방안으로는 차로 합류 및 차단 방안, 주의구간 내 정보 제공 방안, 공사구간 속도 관리 방안, 공사구간 경고 정보 제공 방안, 공사구간 교통안전시설 도입, 공사구간 안전성 효과분석 및 모니터링 방안을 제시하였다.
