실시간 스트림을 지원하기 위한 주문형 서버에서의 버퍼 공유 정책

박용운,홍규완 동의공업대학 2000 論文集 Vol.26 No.1

In this paper, we present a new buffer pool management scheme designed for video type news objects to build a cost-effective News On Demand storage server for serving users requests beyond the limitation of disk bandwidth. With our proposed buffer cache management scheme, a requested data is check to see whether or not it is worthy of caching by checking its average arrival interval and current disk traffic density, Subsequently, only granted news objects are permitted to get into the buffer pool, where buffer allocation is made not on the block basis but on the object basis. By using this caching policy, the frequently accessed objects are cached and then subsequent streams for those objects are serviced directly from the buffer pool, not contacting the disks where the original copies resides: this eventually leads to the construction of a storage server with relatively low costs.

The fluidity of high flowing concrete can be affected by numerous parameters which characterize either the cement or the admixture. The reactivity of a cement as determined by its chemical compositions (especially its C₃A content), its fineness and its content in sulfates and alkalies obviously plays a key role in rheology of high flowing concrete in fresh state. Specific properties of high range water reducing AE agent used to enhance the workability of high flowing concrete also exert important influence. The purpose of this experimental study is to investigate and analyze the effect of cement and high range water reducing AE agent in fluidity, setting, compressive strength of high flowing concrete. As a result, we found that fluidity of high flowing concrete is affected greatly by kind of cement and high range water reducing AE agent, also, there is harmonic character between high belite cement and polycarbonic acid high range water reducing AE agent.

Park,Yong-Jin,Cho,Gyu-Taek,Ma,Kyung-Ho,Lee,Sok-Young,Lee,Jung-Ro,Kim,Young-Chang,Cho,Eun-Gi,Kim Chang-Yung,Nam,Jung-Hyun,Rao,V,Ramanatha,Kang,Hee-Kyoung 한국자원식물학회 2004 Plant Resources Vol.7 No.2

Genetic background and phylogenetic relationships among 20 Korean wheat cultivars were assessed using microsatellites after amplifying with 13 SSR primer pairs. Average allele number per primer pair was 3.36. Genetic similarities for every pair of cultivars ranged from 0.42 to 0.97, with 0.69 of overall average. Korean cultivars were divided into two major groups based on microsatellite DNA polymorphisms. Group I consisted of relatively old cultivars developed until 1970s, and group II contained the recent cultivars developed during 1980s and 1990s. Amongst old elite cultivars/lines, ‘Yukseung 3’, ‘Norin 12’ and ‘Norin 72’ contributed most to the genetic background of cultivars belonging to group I, and ‘Norin 4’, ‘Norin 12’, ‘Norin 43’ and ‘Norin 72’ to group II, respectively. The phylogenetic relationship of Korean wheat cultivars was in accordance with the genealogical data of each cultivar. The genetic background of each cultivar was assessed from the point of breeding and germplasm management such as variety identification and duplicated accessions for assisting in developing a system for the registration of new variety based on the molecular characterization in future.

식민지 시기 문인기자들의 글쓰기와 검열

박용규 동국대학교 한국문학연구소 2005 한국문학연구 Vol.0 No.29

식민지 시기 민인들 중 상당수가 생계의 유지를 위해서,또는 발표의 장을 확보하기 위해 기자로서 활동했다. 작품 활동만으로는 생계유지가 어려웠고, 그나마도 작품 발표의 기회를 잡기도 쉽지 않았기 때문이다. 한편 신문사 입장에서는 훈련 받은 기자가 거의없는 상황에서 당장 활용할 수 있다는 점 때문에 문인들을 기자로 채용했던 것이다. 또한 원고료를 제대로 줄 수 없는 재정 상황 속에서 신문이나 잡지의 문예물 중 상당수를 소속 문인기자들이 해결해 줄 것을 기대했다는 점도 작용했다. 1920년대부터 이미 미디어에 대해 일제의 강력한 통제가 가해졌고, 특히 1930년대에 들어서서는 최소한의 비판적 내용조차 용납되지 않는 가혹한 탄압이 행해졌다. 한편 미디어들로서는 자본 규모가 커지고 경영도 안정되면서 압수와 같은 탄압이 가져 올 경제적 손실에 민감한 반응을 보이게 되었다. 이것은 곧 내적 통제를 가져와 기자들이 이제는 경영진이나 편집간부들의 눈치까지 보아야 하는 상황이 되었던 것이다. 이렇듯 외적 통제뿐만 아니라 내적 통제까지 받으면서 활동해 가는 과정에서 점차 자기 검열을 하게 되었다. 기자로서의 활동이 문인으로서 작품 활동을 하는 데 얼마나 영향을 주었는지를 정확히 알 수는 없다. 식민지 시기 작품 활동을 하며 검열을 경험했던 사실을 털어놓고 있는 문인들 중 대부분이 당시에 기자로서도 활동했던 인물들이다. 내적 통제가 강회되면서 검열에 더 민감했던 문인기자들은 검열의 고통을 호소하기도 했고, 또 다양한 방식으로 검열을 피해가려는 시도를 하기도 했다. 따라서 적어도 기자로서의 경험을 지닌 문인들이 검열에 대응하는 방식이 다른 문인들에 비해 더 적극적이었다고 할 수는 있을 것이다. Many writer-journalists who were writers and concurrently journalists worked for a newspaper or a magazine during the Japanese colonial period. Many writers wanted to get a job with the media to earn their living and to publish their works because they had a great difficulty in finding a job and publishing a work in those days. The media owner and manager preferred writers as a reporter who could write articles without a long training and provide many works for the media without charge. Permitting the Korean media, the Japanese colonial authorities did not want it to become a threat to their rule in Korea. And so they intensified control over the media contents and reconstructed media control system continually during the whole colonial period. The media-capitals gradually adapted to the rigid censorship system and imposed the self-censorship on journalists in the media. Confronted by the rigid exterior and interior control, most of writer-journalists were all under heavy pressure to self-censor to stay in the media. Many writer-journalists eagerly tried to escape from censorship in various ways because they had experienced the pain of censorship in writing articles and works. Although they usually used complaisant words which were permitted by the Japanese colonial authorities, they still attempted to escape from censorship in the way using a roundabout or a symbolic expression.

한국언론의 북한보도 현황과 통일 지향성에 관한 연구

박용규 尙志大學校 1998 論文集 Vol.19 No.-

The purpose of this study is to examine the present state of reporting about North Korea and the direction toward national unification in the Korean Press. The contents of articles reported by the Korean Press have given a great effect on Koreans' recognition of North Korea and formation of public opinion related North Korea. But there have been many elements restricting news gathering and reporting about North Korea. Among them, the most powerful has been the government. The government has restricted reporting about North Korea by controling and mobilizing the press. And the properties of the Korean press. which is substantially commercial and conservative, have exerted a vicious influence on reporting about North Korea. Owing to the commercialistic competition and the ideological constraints, reports on North Korea in the Korean press have been sensational and partial. Consequently the image of North Korea reported by the Korean press has been negative on the whole. As the Korean press has emphasized the warmongering and fabrication of North Korea, the heterogeneity between North and South Korea is solidified. This is considered to be caused by the distrust and hostility for North Korea. After all, there are so many things to improve in reporting about North Korea in the Korean press. First of all, the Korean press has to make efforts to report about North Korea correctly and impartially. And the Korean press must try to play an important role in national unification. In other words, the tasks of the Korean press, above all, are to make trust between North and South Korea and to recover national homogeneity.

모균증은 진균 감염증의 하나로 급성으로 진행되며 사망률이 높은 질환이다. 다양한 임상 양상으로 나타나며 두부 모균증이 가장 흔한 형태이다. 두부 모균증의 임상 경과는 감염의 해부학적 위치에 따라 두통, 안면 부종, 압통부터 안구 돌출, 안구 마비, 시력 소실 등 다양하게 나타난다. 모균증은 혈관계를 잘 침범하며, 두부 모균증의 경우 해면 정맥동의 침범뿐 아니라 아주 드물게 내 경동맥이나 두강 내 혈관을 침범하는 경우도 있다. 저자들은 뇌혈관 질환이 동반된 두부 모균증의 드문 합병증 3예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

고속도강을 이용한 CFRP 복합재료의 드릴가공 특성

조규재,박종남,정용운 朝鮮大學校 機械技術硏究所 2005 機械技術硏究 Vol.8 No.1

복합재료는 각 종 기계부품, 우주항공산업, 자동차의 내장재와 구조재, 건축구조물, 선박 재료, 스포츠용품 등 다방면에서 유용하게 사용되어지고 있다. 복합재료는 여러 가지의 대체 재료로서 타 산업에 비하여 활용의 가치가 높다. 그러나 기계가공분야에서는 가공의 어려움으로 인하여 활용도가 미흡한 상태이다. 따라서 본 논문에서는 CFRP를 수직형 머시닝센터에서 고속도강 드렬로 가공한 후 흘 가공 입 · 출구부에서 표면이 고르지 못함을 확인하였으며, 가공을 할수록 유동형의 긴 칩에서 분진형태로 변하는 칩의 형상 등을 관찰하였다. Composite materials are widely used in all kinds of machine parts, aerospace industries, internal and structural materials of cars, building structures, ship materials, sporting goods, and others. It is worth while to use the composite materials as various substitutions compared with others. But it is limited to use them in the field of the mechanical processing because of the difficulties in cutting. Thus it is proved that the surface roughness is in and out of the hole processing after cutting the CFRP with HSS drilling in the vertical machining center. And it is observed that the more it is processed, the more the fluid long chip is changed into the powdered chip.
