Real-time application programs have constraints which need to be met between media-data. These constraints represents the delay time ad quality of service between media-data to be presented. In order to efficiently describe the delay time and quality of service, a new synchronization mechanism is needed. Proposed paper is a dynamic synchronization that minimized the effects of adaptive transmission delay time. That is, the method meets the requirements of synchronization between media-dat by handling dynamically the adaptive waiting time resulted from variations of delay time. In addition, the mechanism has interval adjustment using maximum delay jitter time. This paper decreases the data loss resulted from variation of delay time and from loss time of media-data by means of applying delay jitter in order to deal with synchronization interval adjustment. Plus, the mechanism adaptively manages the waiting time of smoothing buffer, which leads to minimize the gap from the variation of delay time. The proposed paper is suitable to the system which requires the guarantee of high quality of service and mechanism improves quality of services such as decrease of loss rate, increase of playout rate.

출판학 연구 동향 및 특성에 관한 논문 - 한국출판학연구(1982~2006)를 중심으로 : 출판학 연구 동향 및 특성에 관한 논문

이기성(Lee Ki-Sung) 한국출판학회 2006 한국출판학연구 Vol.0 No.51

‘출판학 연구 동향 및 특성에 관한 논문―한국출판학연구(1982~2006)를 중심으로’ 연구 논문은 1982년도부터 2006년 6월 통권 제50호까지 한국출판학연구에 실린 272건의 논문을 분석한 것이다. 본 논문은 서론, 선행 연구 검토, 최종 매체별 구분, 출판 분야 및 단계별 구분, 언어 문자별 구분, 필자별 논문 구분, 결론의 7개 내용으로 구성되었다. 출판에 관한 분류 방법에 대하여는 민병덕 교수, 이기성 교수, 남석순 교수, 이종국 교수, 팽건염 교수, 기륜성남 교수 등 여러 학자가 이미 연구한 바 있다. 필자는 매체별 분류, 분야별 분류, 단계별 분류, 언어 문자별 분류의 4가지를 하나의 같은 범주 내에서 구분하는 것이 아니라 각기 다른 위치(차원)에서 구분하는 것이므로 논문이나 출판물은 하나이지만, 이것을 각기 4가지씩으로 분류하는 방법을 2000년도에 제안한 바 있다. 첫 번째 : 최종 매체(media)에 의한 논문 구분(① 종이 매체, ② 전자 매체(비종이 매체), ③ 공용의 3가지), 두 번째 : 분야(field)에 의한 논문 구분(① 교과서류, ② 단행본류, ③ 잡지류, ④ 신문류, ⑤ 일반), 세 번째 : 단계(step)에 의한 논문 구분(① 기획, ② 편집, ③ 제작, ④ 마케팅, ⑤ 총괄), 네 번째 : 언어(language) 문자에 의한 논문 구분(① 한국어, ② 영어, ③ 중국어, ④ 일본어, ⑤ 기타 문자) 결론적으로 첫째, 출판학이나 출판 산업을 분석하려면 2차원 이상으로 분류하는 방법(멀티차원분석법)이 필요하다. 둘째, 제작 단계와 편집 단계의 논문이 매우 필요하다. 셋째, 출판 관련 논문을 작성하는 필자가 절대적으로 부족하다. This study is divided into 7 parts ; Introduction, Classification systems, Classification -based on output media, Classification -based on publication fields and steps, Classification -based on language and letters, Classification -based on authors, and Conclusion. Theses given in the collection of learned papers of Studies of Korean Publishing Science have been issued from 1982 to 2006 are two hundred and seventy two. Many scholars have suggested the way of analyzing the publications and publishing industry. Professor B.D. Min’s method : General remark, Selection, Production, Distribution, Managing, and History. Professor K.S. Lee’s method : Divided with final output Media, Divide with publication Field(contnents), Divided with publication production Step, and Divided with typeset Language and letters. Professor S.S. Nam’s method : Theory of publishing, Education, Production, Circulation, Reception, Environment, Industry, Electronic Publishing, Law, and International Publishing. Professor J.G. Lee’s method : Theory, Copyright/Morals, Editing/Production, Textbook, Book, Magazine, Electronic Publishing, Management/Industry, Circumstances, International Publishing, and Reading/Reader. In this study, I propose the analyzing publications and publishing industry is not only one dimension but also more than two dimensions according to the angles of vision. The first dimension is divided into 3 sections based on output media, such as Paper, Electron(non-paper), and altogether. The second dimension is divided into 5 sections based on publishing field, such as Textbook, Book, Magazine, Newspaper, and General(the others). The third dimension is divided into 5 sections based on production step, such as Planning, Editing, Production, Marketing, and General(basis). The fourth dimension is also divided into 5 sections based on language and letters, such as Korean character, English, Chinese, Japanese, and the others. Multi Dimension Analysis(MDA) which is using more than two dimensions is the most suitable way of analyzing the publications and the theses related to publishing.

이방성 손상모델을 이용한 콘크리트 구성방정식의 도출

이기성,변근주,Lee, Ki Seong,Byun, Keun Joo 대한토목학회 1994 대한토목학회논문집 Vol.14 No.4

콘크리트는 초기부터 미세균열을 포함하고 있으며 이들의 성장과 전파에 의해 파손이 발생한다. 이와같은 과정을 손상이라 한다. 연속체 손상역학의 개념을 소개하고 열역학 법칙으로부터 자유에너지함수와 소산포텐셜을 가정하여 이차텐서로 나타낸 손상모델의 전개법칙과 구성방정식을 제안하였다. 구성방정식은 탄성과 손상 및 소성을 고려하도록 하였다. 도출된 모델을 이용하여 단조하중에 의한 일축과 이축응력을 받는 콘크리트에 적용하여 그 타당성을 검정하였다. Concrete contains numerous microcracks initially. The growth and propagation of microcracks cause failure of concrete. These processings are termed as "damage". The concepts of the continuum damage mechanics are presented and the damage evolution law and constitutive equation are derived by using the Helmholz free energy and the dissipation potential by means of the thermodynamic principles. The constitutive equation includes the effects of elasticity, damage and plasticity of concrete. The proposed model successfully predicts the nonlinear behavior of concrete subject to monotonic uniaxial and biaxial loadings.

As the basic study to solve the recent big problems upon the bacterial multi-drug resistance recognizing seriously from the viewpoint of microbial ecology, clinical medicine and public health, this study was carried out temporally and spatially upon Kum river area that has been recently accelerated the pollution for the purpose of analysis such as distribution of heterotrophic bacteria, distribution of resistant bacteria upon prevalently utilizing antibiotics(Ampicillin, Amp ; Chloramphenicol, Cm ; Tetracycline, Tc ; Kanamycin, Km ; Streptomycin, Sm) and heavy metal(mercury, Hg ; cadmium, Cd), frequency of multi-drug resistances, frequency of resistant factor transfer, compatibility and/or incompatibility. In May, 1992, community sizes of total heterotrophic bacteria reached to 5×10 exp (7)CFU/㎖ in site 1(1S, Kapchun stream`s water), 5×10 exp (8)CFU/㎖ in site 2(2S, Kapchun soil) where industrial and domestic sewages were chiefly flowed, and reached to 1×10 exp (8)CFU/㎖ in site 3(3S, Sanne stream`s water), 1×10 exp (7)CFU/㎖ in site 4(4S, Sanne soil) where agricultural domestic sewages were. Total heterotrophic bacteria in Kapchun area(1S, 2S) were distributed 50 times higher than those in Sanne area(3S, 4S) respectively. Compared with water, soil contained 10 times higher in heterotrophic bacteria. Of heterotrophic bacteria, compositional ratios of resistant bacteria upon antibiotics and heavy metals were shown to the level of 0.07% in May, 1992 and to the level of 0.2% in October, 1992. So, frequency of resistant bacteria increased in October about 3 times higher than in May. The frequent order of resistant factor was Tc, Km, Cd, Amp, Hg, Cm, in May, 1992 and was Cd, Amp, Sm, Hg, Km, Tc, Cm, in October, 1992, respectively. Especially, Cd resistant bacteria were distributed upon all experimental sites more frequently in October, 1992 than in May, 1992. Passing through the rainy period in summer, the distributional change of resistant bacteria indicate strong evidence for the influx of large amount of sewage containing lots of resistant bacteria and of pollutants to the Kum river area. Considering the genetic linkage between antibiotics resistance and heavy metal resistance and distributional change of multi-drug resistant bacteria, resistant factor such as Tc, Amp, Cd were shown the highest frequency of simultaneous coexistence, so they are closely linked with other resistant factors the most from the viewpoint of molecular genetics. Most of resistant bacteria comprise generally simultaneous multi-drug resistance upon 5 to 3 drugs. As especial results, considering the relationship of simultaneous coexistence in antibiotics and heavy metal resistance, Cd resistance bacteria comprise other resistance factors such as Tc(70%) and Amp(68%) simultaneously and frequently and Hg resistant bacteria, such as Tc(80%) and with Cd(70%). In the transferability and incompatibility upon resistant factors, only 1% of resistant factors was the conjugative, transferable type plasmid, and 99% of them showed the incompatibility in the other strains.
