Shocks are ubiquitous in astrophysical plasmas: bow shocks are formed by the interaction of solar wind with planetary magnetic fields, and supernova explosions and jets produce shocks in interstellar and intergalactic spaces. The global morphologies of these shocks are usually described by a set of magnetohydrodynamic (MHD) equations which tacitly assumes local thermal equilibrium, and the resulting Rankine-Hugoniot shock jump conditions are applied to obtain the relationship between the upstream and downstream physical quantities. While thermal equilibrium can be achieved easily in collisional fluids, it is generally believed that collisions are infrequent in astrophysical settings. In fact, shock widths are much smaller than collisional mean free paths and a variety of kinetic phenomena are seen at the shock fronts according to in situ observations of planetary shocks. Hence, both the MHD and kinetic equations have been adopted in theoretical and numerical studies to describe different aspects of the physical phenomena associated with astrophysical shocks. In this paper, we present the results of 3D relativistic particle-in-cell (PIC) simulations for ion-electron plasmas, with focus on the shock structures: when a jet propagates into an unmagnetized ambient plasma, a shock forms in the nonlinear stage of the Weibel instability. As the shock shows the structures that resemble those predicted in MHD systems, we compare the results with those predicted in the MHD shocks. We also discuss the thermalization processes of the upstream flows based on the time evolutions of the phase space and the velocity distribution, as well as the wave spectra analyses.

This study examined whether scanning could be performed with minimum dose and minimumexposure to the patient after an attenuation correction. A Hoffman 3D Brain Phantom was used inBIO 40 and D 690 PET/CT scanners, and the CT dose for the equipment was classified as a low dose(minimum dose), medium dose (general dose for scanning) and high dose (dose with use of contrastmedium) before obtaining the image at a fixed kilo-voltage-peak (kVp) and milliampere (mA) thatwere adjusted gradually in 17 - 20 stages. A PET image was then obtained to perform an attenuationcorrection based on an attenuation map before analyzing the dose difference. Depending on tubecurrent in the range of 33-190 milliampere-second (mAs) when BIO 40 was used, a significantdifference in the effective dose was observed between the minimum and the maximum mAs (p <0.05). According to a Scheffe post-hoc test, the ratio of the minimum to the maximum of theeffective dose was increased by approximately 5.26-fold. Depending on the change in the tubecurrent in the range of 10-200 mA when D 690 was used, a significant difference in the effectivedose was observed between the minimum and the maximum of mA (p < 0.05). The Scheffe posthoctest revealed a 20.5-fold difference. In conclusion, because effective exposure dose increaseswith increasing operating current, it is possible to reduce the exposure limit in a brain scan can be reduced if the CT dose can be minimized for a transmission scan.

A Hoffman 3D Brain Phantom was used to evaluate two PET/CT scanners, BIO_40 and D_690, according to the radiation dose of CT (low, medium and high) at a fixed kilo-voltage-peak (kVp) with the tube current (mA) varied in 17~20 stages (Bio_40 PET/CT scanner: the tube voltage was fixed to 120 kVp, the effective tube current (mAs) was increased from 33 mAs to 190 mAs in 10 mAs increments, D_690 PET/CT scanner: the tube voltage was fixed to 140 kVp, tube current (mA) was increased from 10 mAs to 200 mAs in 10 mAs increments). After obtaining the PET image, an attenuation correction was conducted based on the attenuation map, which led to an analysis of the difference in the image. First, the ratio of white to gray matter for each scanner was examined by comparing the coefficient of variation (CV) depending on the average ratio. In addition, a blind test was carried out to evaluate the image. According to the study results, the BIO_40 and D_690 scanners showed a <1% change in CV value due to the tube current conversion. The change in the coefficients of white and gray matter showed that the Z value was negative for both scanners, indicating that the coefficient of gray matter was higher than that of white matter. Moreover, no difference was observed when the images were compared in a blind test.

Two cases of postoperative chylothorax treated with parenteral octreotide and conservative therapy

최은진,이섭,Choi, Eun Jin,Lee, Sub The Korean Pediatric Society 2007 Clinical and Experimental Pediatrics (CEP) Vol.50 No.3

Chylothorax is a rare complication following cardiac surgery for congenital heart diseases. Although conservative management is successful in the majority of cases, surgical intervention is required in a refractory one. Recently, subcutaneous or intravenous infusion of octreotide has been used as a safe treatment that helps avoiding surgical intervention. Herein, we report two cases of postoperative chylothorax treated with parenteral octreotide and conservative therapy. 선천성 심장병의 수술후 발생되는 유미흉은 드문 합병증이다. 이는 수분, 전해질 및 영양의 불균형을 초래할 뿐만 아니라 감염에 취약함을 보이기도 한다. 지금까지의 보존요법에 대해 비교적 치료성적이 좋으나 치료에 반응하지 않는 경우에는 수술적 중재가 불가피하다. 저자들은 보존요법과 octreotide 주입을 병행하여 수술적 중재를 피하고 효과적으로 치료한 수술후 발생된 유미흉 2례를 보고하는 바이다.

1920년대 말~1930년대 초 대공황기 식민지 조선 상인의 경제위기와 대응

최은진 한국역사연구회 2022 역사와 현실 Vol.- No.125

Due to the Great Depression, Japan pushed ahead with fiscal austerity and industrial rationalization, and a lot of small merchants in colony Chosun failed to be protected politically and went broke. Especially, it was the problem that Japanese merchants enjoyed convenience benefited by enormous capital and political support and snatched away Chosun people’s commercial supremacy. Coping with the economic crisis, the merchants held commercial meetings, asked for the installation of financial agencies for retailers, or engaged in movements to lower the rent in commercial associations. And there was a movement to organize separate chambers of commerce for Chosun people in order to advance the commerce for Chosun people by placing endeavors for joint purchase and consistent market price to maintain the status quo of small merchants. However, most chambers of commerce were organized by both merchants of Chosun people and Japanese that such a plan did not pan out as purported.

중국의 ‘중국학’연구의 지적구조와 네트워크: 텍스트 마이닝 기법을 활용한 새로운 분석방법의 모색

최은진 한국동북아학회 2016 한국동북아논총 Vol.21 No.2

This study explored the research trends in China Study carried out in China adopting informetrics method. To do this, I extracted 46 keywords from the 233 relevant articles listed up in CNKI until the end of 2015 and focused on co-words to grasp the theme of the research in terms of the overall and detailed aspects. On the whole, it could be ascertained that classical liberal arts formed a large and influential proportion in Chinese study which has been linked with advanced Sinology researches in overseas, the influence of Sinology in France and Japan was far-reaching than that of US Sinology. Therefore, it could be seen that the Chinese Study in China concentrated in understanding the Sinology of the West. It was indicated that the prominent scholar, such as Fairbanks and Schwartz(US),Paul Demiéville and Edouard Chavannes(France), MizoguchiYuzo(Japan) made great impact on, also became the main subjects of Chinese Study. According to author profiling analysis, the network of the agency was a major factor to form the connection between the researchers, but there's also the network connection unrelated to the agency. One interesting fact from the quantitive analysis was that the researchers of frequently quoted were made up the core group. Since the database construction of the current academic materials was underway in large parts and expected to be easily accessible to, using the quantitive method would enable to reveal the paradigm shift or the internal structure of the study and it is viewed to enrich the humanities research. 이 연구는 계량정보학적 기법을 사용하여 중국의 중국학 관련 연구의 동향을 분석한 것이다. 이를 위해 CNKI에서 검색된 2015년 12월말까지의 중국학을 주제로 하는 관련 주저자 57명 논문 223 편의 키워드 46종을 추출하여 분석 자료로 삼았다. 동시출현단어 분석을 통해 전체적 측면에서 또한 세부적 측면에서 연구영역의 주제를 파악해 보았다. 키워드 네트워크 분석을 통해 살펴본 중국학 연구의 지적 구조에는 중국학 연구가 지역연구로서의 중국학 보다는 학술연구의 차원에서 전통적 한학연구가 주요한 주제가 되는 것을 보여준다. 그러므로 중국에서 이루어지고 있는 중국학 연구는 서구의 전통적 한학을 이해하려는 입장이 강하며 각국의 중국학 가운데 일본과 미국 및 프랑스의 한학과 중국학에 대한 연구를 중심으로 하는 것을 알 수 있다. 주로 연구되는 대상이자 영향을 끼쳤던 주제는 페어뱅크, 슈워츠 등 미국 중국학자 및 프랑스의 펠리오와 드미에빌(戴密微 Paul Demiéville), 샤반느(Edouard Chavannes 沙畹)와 일본의 미조구찌유조(溝口雄三) 등 학자인 것으로도 나타났다. 저자들에 대한 프로파일링 기법에 따른 분석에 의하면 연구자의 소속기관에 따라 주로 연계를 맺지만 소속기관과 관련 없는 네트워크도 형성되는 것으로 드러났다. 흥미로운 것은 연구자의 양적 데이터를 통한 분석에서도 인용회수가 높은 연구자가 중요한 집단을 이루는 것으로 나타났다는 점이다.
