New Aggregation Algorithm for Tandem queue with Finite Buffers

김종환,Hur, Sung Kwan,徐承祿 大邱大學校附設 基礎科學硏究所 1991 基礎科學硏究 Vol.8 No.-

We consider a two-stage fmite tandem queueing system with Poisson arrivals and negative exponential service times. The customer who has completed his service at the first station has to go directlty to the second station. If the queue of the second station is full at the moment of the service completion of the customer at the first station, then the customer receives, another service at the first station. This is repeated until the customer completes a service at the first station at the moment that the second station is not fulL The problem of calculating the steady-state probabilities of this queueing system by the ordinary balance equations is time consuming. We develop an efficient algorithm to obtain the steady-state probabilities that utilize the two-way state aggregation techniques.

This study is a part of E. B. S(Environmental Behavior Study) and understanding the enviornmental recognition and perception and behavior attitude following the general psychological process of human in environment. For the being free in space, it is most desirable that the discrimination, namely, unique image is achived by the environmental information. In the behavior characteristics being showed on the behavior setting of man, the trend that people try to interpret and act the environmental information by himself is typical. In the light of behavioral attribute pelple try to interpret and act the environmential information by decision making, the methods that can enrich the information or the common image from the nature and funtion at place is demanded.

김종환,최은혁,박광서,윤대희,김이국,이광식,Kim, Jong-Whan,Choi, Eun-Hyuck,Park, Kwang-Seo,Yoon, Dae-Hee,Kim, Lee-Kook,Lee, Kwang-Sik 한국조명전기설비학회 2005 조명·전기설비학회논문지 Vol.19 No.8

고본 연구는 모의 GIS내 절연특성을 $SF_6$ Gas의 온도의 변화($+30{\sim}-40[^{\circ}C]$)에 따른 절연특성을 구명하였다. 절연 특성은 기체상태의 Paschen's law 적용구간, 기체와 액체 공존상태의 절연파괴전압이 대세적으로 높고, 편차가 심한 구간과 챔버 내부가 저밀도 $SF_6$와 잔류공기의 혼합체로 이루어지는 극히 낮은 압력상태로 되어 절여파괴 전압이 크게 낮아지는 구간으로 구분되었다. 또한 본 실험에서 액체 $SF_6$가 기체 $SF_6$보다 절연특성이 우수함을 확인하였다. 상전이와 절연특성을 구명함으로서 각종 고온초전도 및 극저온 응용 설비의 절연설계의 기초 자료로 제공하고자 한다. In this paper, insulations characteristics by temperature changes($+30{\sim}-40[^{\circ}C]$) of $SF_6$ gas in the experimental chamber were studied. From this result, The breakdown characteristics classify the vapor stage of $SF_6$ according the Paschen's law, the gas & liquid coexisted stage of voltage value increases & much deviation and the VB low stage as the interior of chamber gets filled with mixture of $SF_6$ that are not liquefacted and remaining air which couldn't be ventilated. In addition the ability of insulation of liquid $SF_6$ was higher than that of the highly pressurized $SF_6$ gas. In this research, we want to provide the base data on designing insulation of high-temperature superconductor and the cryogenic equipments by investigating the insulation characteristics of $SF_6$.

農村地域 靑小年들의 身長과 體重間의 相關性과 標準體重値에 關한 硏究

金宗煥 韓國體育大學校 1983 論文集 Vol.5 No.-

A study on 5671 (boys ; 2886, girls ; 2785) primary, middle and high school students in a rural area (Chun Ra province) was conducted for assessing their physical growth and development, an correlation coefficients and regression equation between body height and weight from May 1, to June 30, 1978 and the following results were obtained. 1. Physical growth and development 1) Body height Rapid growth of physical growth in terms of body height has been observed among males in the age 7-16 and among females 7-15. Growth in terms of body height turned out to be slower among students of height ages by both sexes. This indicates that girls enter a rapidly growing stage 2 years earlier than boys. The age of cross over between both sexes in between 9 to 12.5 year where upon female out grows male. The maximum annual growth rates were 6.8 cm from 12 to 13 years of age for male and 6.4 cm from 10 to 11 for female. 2) Body weight Rapid growth of physical growth in terms of body weight has been observed among both of sexes in the age 7-16. Growth in terms of body weight turned out to be slower among students of higher age by both sexes. This indicates that girls enter a rapidly growing stage 2 years earlier than boys. The age of cross over between both sexes in between 9.5 to 13.5 years where upon female out grows male. The maximum annual growth rates were 5.8 kg from 14 to 15 years of age for male and 4.9 kg from 12 to 13 for female. 3) The standard of growth of rescent Korean students show much improved than that of 1967. 2. The coreelation coefficients between body height and body weight are indicative of moderately correlated conditions by age and sex as showed in table 4. 3. Highly significant correlations helped estabish linear regression equation for body weight from height by age and sex as showed in table 4.

Today when everything is rapidly changing into the digital media-base circumstance, it is necessary to recognize the importance of basic modeling across the whole curriculums on image design and reestablish the province of basic modeling into a more extensive and comprehensive concept based on the analysis of new paradigms. Especially, it is true that a rapid shift of the production environment into the digital media brings a sense of estrangement from the analog method in concept, modeling and function, causing a substantial confusion in the first-line running of curriculum. The purpose of this study is to see in new lights the province of basic modeling in media design in a way that matches new cultural paradigms, and develop effective and realistic basic education programs capable of being commonly applied to the digital animation-related province with a high reliance on tools and actually apply them to new subjects. In addition, mistakes in operation can be corrected gradually by repeating a cyclic course whereby a few stages of exemplary subjects are run and realistic data are drawn. Also, this will help enhance the capabilities of students majoring in this field for adapting to and operating digital media by securing stable and effective basic data that can be reflected in basic subjects of actual special study, and ultimately promote their capabilities for adapting to reality and social competitiveness. 디지털미디어 기반의 환경으로 급속히 변모하는 오늘날, 영상디자인의 교과과정에 있어서 기초조형교육의 중요성을 인지하고 새로운 패러다임 분석을 바탕으로 보다 확장되고 포괄적인 개념으로 기초조형의 영역을 재조명할 필요가 있다. 특히 제작환경의 디지털 매체로의 급격한 변화는 기존 아날로그 방식의 조형교육과의 개념적, 조형적, 기능적 괴리감을 가져와 일선 교과과정 운영에 있어서 상당한 혼란을 야기 시키고 있다고 보여 진다. 본 연구의 목적은 영상디자인에 있어서 기초조형의 영역을 새로운 문화 패러다임에 걸맞게 재조명하고 툴 의존도가 높은 디지털 애니메이션 관련 영역에 공히 적용될 수 있는 효율적이고 현실적인 기초 교육 프로그램을 개발하여 신규교과목에 실제로 적용하는 것이다. 이의 효과적 적용을 위해서 기초조형교육의 유형을 전반적으로 파악하고 디지털미디어의 영역으로 확대 해석하여 기초조형의 원리의 재정립할 필요성이 있으며 이를 토대로 디지털 애니메이션 분야의 중요한 요소인 움직임, 시간, 상호작용, 등의 기초적 개념을 확립하고 해당 분야의 미디어환경에 포괄적 적용이 가능한 기초교육 프로그램의 개발을 위한 자료로 활용한다. 또한 몇 단계의 시범교과목을 운영하여 현실적인 데이터를 도출하는 순환 과정을 되풀이함으로써 점진적으로 운영상의 오류를 수정해 나갈 수 있는 기초 자료를 확보하여 보다 안정적이고 효율적으로 실제 전공 기초 교과목에 반영함으로서 전공학생들의 현실 적응력과 경쟁력 향상을 도모 한다.
