한국 신문의 과학 보도에 나타난 취재원 분석 : 조선일보와 한겨레신문의 미국 쇠고기 수입 관련 과학 기사의 경우
고흥석,이건호 梨花女子大學校 社會科學大學 社會科學硏究所 2010 사회과학연구논총 Vol.24 No.-
본 연구는 2008년 중반기 미국산 쇠고기 수입 문제와 관련, 각각 보수와 진보의 대표로 알려진 조선일보와 한겨레신문이 해당 이슈의 과학적 정보를 보도하는 과정에서 취재원을 어떻게 활용했는지 조사했다. 탐구 결과, 두 신문들의 취재원은 모두 행정부와 입법부에 편중되어 있으며, 제일 신뢰도가 높다고 인정되는 전문가 취재원들을 사용해 자신들의 이념 성향을 ‘명확히’하고, 또 신뢰도 순위가 전문가 보다 낮은 행정부 및 시민·사회단체, 일반 시민 취재원은 정치적 성향을 ‘은밀히’ 보완하는 도구로 활용된 점이 조사됐다. 또 두 신문 모두 일정 수준의 취재원 투명도를 확보하고 있으나 일부 취재원 범주에서는 투명도의 차이가 나타났다. 결국 과학적 사실마저도 언론의 이념적 성향에 따라 편향되게 보도된다는 것이다. Conducting a quantitative content analysis of science-related news articles about U.S. beef imports to Korea presented in Chosun Ilboand Hankyoreh Shinmun for six months in the middle of 2008, this study explores the newspapers’ source use. The study found that both the conservative Chosun Ilbo and the progressive Hankyoreh Shinmun used the experts, the most credible source, to endorse their own political agenda. In addition, the results of this study shows that they used the administration and NGOs as sources, which rank at the middle range in the credibility order, and the citizens, which are at the bottom of the order, as camouflages to hide the politically predisposed newspapers’ bias, but eventually to promote their ultimate political goals. The paper concludes that even the scientific facts that are supposed to be impartially reflected in the news stories are translated into politically value-laden information.
SM570 QT강 다층용접부에서 저온 균열방비를 위한 예열온도에 대한 연구
고진현,김건형 한국기술교육대학교 2006 論文集 Vol.13 No.1
A preheat temperature to prevent the cold cracking of SM570 QT structural steel weldments made by depositing multiple weld passes in the V-groove with FCAW was evaluated. The diffusible hydrogen content in the deposited weld metals increased linearly with increasing the hydrogen content in the shielding gas. It was confirmed that the cold cracking occurred in the weld specimens with preheat temperature at 50℃ and shielding gas of Ar+20%CO_(2) regardless of hydrogen content. On the other hand, the cracking did not occur in the wledments made with preheat and interpass temperatures at 75℃ and 100℃. Based on this study, it is suggested that the minimum preheat temperature to avoid the cold cracking for SM570 QT steel weld metal is 75℃.

The Idling time (IT) matrix is proposed to schedule job patching sequences in automated manufacturing systems. Using the method, the idling time of resources can be minimized. The job sequence is modeled by Neural Petri Nets with a time constraint to generate real time control signals. The results are applied a simple automated assembly system consisting two robots and a conveyor.

In this paper, I-PD controller by nearal network is designed using variable structure controller. The I-PD control system is stable in the sense that the error is inside the constraint set, the variable structure controller is idle. If the error hits the boundary of constraint, the variable structure controller begins operation to force the error back to the constraint set. Applying this control technique to the position control system using a DC servo motor as a driver, the control performance of controller is verified by the results of computer simulation.

주지역에 분포하고 있는 귀화식물의 분포 현황을 조사하고 분포특성을 분석하였다. 그 결과 제주지역의 외래식물은 47 과 161 속 248 종 6 변종으로 총 254 분류군이었다. 생육특성에 따른 구성은 일년생 초본이 107 분류군(42.13%)으로 가장 큰 비율을 차지하였으며, 생육형 구성은 직립형이 79 분류군으로서 전체의 31.1%를 차지하여 가장 높은 비율을 차지하였고, 번식형은 연결체가 없는 단위식물형이 203 분류군으로서 전체의 79.9%를 차지하였다. 생활형 분석결과 휴면형 구성은 일년생식물이 150 분류군으로 전체의 59%로서 대부분을 차지하였으며, 다음으로는 반지중식물이 53 분류군(20.9%), 지중식물이 26분류군(10.2%)의 순이었다. 원산지별 구성은 유럽이 115 분류군으로서 전체의 36.7%를 차지하여 가장 많았으며, 다음은 아시아가 69 분류군(22.0%), 북아메리카가 59 분류군(18.8%)의 순이었다. 도입배경은 사료 또는 곡물혼입이 가장 높은 비율을 차지하였다. The distribution and status of naturalized plants in Jeju Island were investigated in this study. As results, the naturalized plants in Jeju Island were total of 254 taxa including 47 families, 161 genera, 248 species and 6 varieties. By the growth habits, annuals held the most percentage including 107 taxa (42.13%). Seventy nine taxa (31.1%) were appeared to have erect type in growth forms and 203 taxa (79.9%) are non-clonal growth form in disseminule forms by radicoid. The most of dormancy form in life form were therophytes as 150 taxa (59%), and following as 53 taxa (20.9%) for hemicryptophytes, and 26 taxa(10.2%) for geophytes. Among the naturalized plants, 115 taxa (36.7%) were originated from Europe, 69 taxa (22%) from Asia and 59 taxa (18.8%) from North America. Twenty eight percent of them were introduced as feeds or mixed seeds of imported cereals.

Talus tuberculosis is a rare disease, even in an endemic tuberculosis area. In reviews of the worldwide literature, only 18 cases of talus tuberculosis have been reported. Recently, we experienced a case of a 70-year-old polycythemia vera patient with right metatarsopharyngeal joint pain for 2 months duration who was diagnosed with talus tuberculosis with prostate involvement. Tuberculosis should be considered as one of the causes of monoarticulitis, especially in countries, where the disease is endemic. Additionally, we highly recommend taking a biopsy of the site of suspected infection because an early diagnosis is the key to successful treatment.
