Water Gas Shift (WGS) 공정에 대한 분리막 반응기의 동적 모사

오민,이용,홍성욱 한국막학회 2010 멤브레인 Vol.20 No.3

본 연구에서는 Water Gas Shift (WGS) 반응이 일어나는 분리막 반응기 (MR) 대상공정에 대해서 동적모사 (dynamic simulation)를 실시하고 시간과 위치에 따른 온도 및 수소 농도 변화 등을 살펴보았다. 모사 결과에 의하면 도입부에서 반경방향으로의 수소 농도, 수소 분압 및 온도차가 가장 컸으며 출구에서 가장 작았다. 또한, 수소분압의 차이가 가장 큰 도입부에서 수소의 flux가 가장 크게 나타나며 출구에서 일산화탄소의 전환률은 0.65였다. In this study, dynamic simulation of membrane reactor was performed for water gas shift reaction and temperature, hydrogen concentration, etc. were investigated as a function of time and position. Simulation results indicated that differences of hydrogen concentration, hydrogen partial pressure, and temperature in the radial direction, were larger in the entrance than in the exit. In addition, the hydrogen flux was the largest in the entrance, where the hydrogen partial pressure difference was the largest, and the conversion of carbon monoxide in the exit was about 0.65.

A device was used to integrate side light from a Yb-doped optical fiber. The integrated side-light spectrum was analyzed by using a spectrometer. The side light from the fiber was measured as a function of the distance from the input end of diode-pumped fiber. Diodes with 915 nm or 976 nm wavelengths were used for pumping. When the pump power was very low, an exponentially decreasing fluorescence signal was observed. the absorption coefficient of the Yb-doped fiber at the pump diode's wavelength was measured by fitting the exponentially decreasing fluorescence signal. The measured results were compared with the results obtained by using the cutback method. When the pump's power intensity was larger than 2 W, the 976 nm fluorescence signal deviated from a simple exponentially-decreasing behavior due to amplified spontaneous emission in the case of the optical fiber with a 10 $\mu$m core diameter. The fluorescence signal increased with increasing distance from the fiber input end and reached a maximum, after which it decreased with increasing distance. The maximum position depended on the pump's power.

史述与想象——《回归天堂》的诗化策略

오민 한국중국언어문화연구회 2009 한중언어문화연구 Vol.- No.21

The paper, based on historical narrative and poetic strategies in "Return to Paradise", points out that Xia Niansheng is expert in characterization and rendering emotion by using imagery and area background. Due to giving full play to the characteristics’ strong emotion, the writer promoted plot and emotion ups and downs, by interview notes, narrative plot or the hero’s inner monologue alternately. Because the writer explored more deeply the heroic acts in the meaning of human life, "Return to Paradise" has distinctive difference from other novels about Korean in the war.

没有一次牺牲不是壮烈的 — 无名氏韩人抗日题材小说论

吳敏 한국중국언어문화연구회 2008 한중언어문화연구 Vol.- No.15

From the literature interior and exterior, the article researched seperately and detailedly to three novels written by Wu Ming Shi on the korean's resistance to Japanese. After analysing to their artistic technique, the article pointed out that the novels written by Wu Ming Shi have mixed expanse and expatiation with simpleness and realism. It is the extension and variation of "narration on hero", enthused over by enlightening writers in May 4th movement that Wu Ming Shi described and craved "others" hero. It expressed relativity of recognization between "others" and "ego" in modern China. The aim to discuss these "no attention" works is to research the novels on Korean in the Chinese modern literature completely and to call out attention and research to the early works written by Wu Ming Shi in academe.

치파오의 조형적 특성을 응용한 웨딩드레스 디자인 연구

오민,김정숙 한국패션디자인학회 2011 한국패션디자인학회지 Vol.11 No.1

2000년대 들어 중국은 국민들의 생활수준이 향상됨에 따라 일반 대중의 패션에 대한 욕구가 증대되고 있다. 더불어 중국민의 웨딩드레스에 대한 욕구 수준도 점차 높아져 웨딩드레스 디자인은 더욱 개성화 · 다양화 되고 있다. 따라서 이러한 요구에 부응하는 웨딩드레스의 경쟁력을 갖추기 위해서는 전통성과 국제화의 조화를 이룬 창의적 디자인이 필요하다. 이와 같이 중국적인 독창성과 차별성을 갖춘 웨딩드레스가 요구되는 실정이나 중국 전통 복식인 치파오 이미지를 응용한 웨딩드레스 디자인 연구는 전무한 실정이다. 본 연구에서는 문헌연구를 통해 치파오를 고찰한 후, 청대와 근 · 현대 치파오의 조형적 특징을 비교 분석하였다. 치파오의 조형적 특징을 실루엣, 개금의 형태, 칼라의 형태, 소재의 종류, 트리밍 기법으로 나누어 살펴보았다. 앞의 분석 결과를 토대로 치파오의 조형적 특성을 응용한 웨딩드레스 디자인으로 3작품을 제작하였다. 본 연구의 목적은 중국의 전통 문화와 중국인의 정서가 반영된 치파오를 응용한 창의적 웨딩드레스를 개발하고, 향후 중국시장을 비롯하여 세계시장에 적합한 경쟁력 있는 디자인을 제안하기 위함이다.

The proper management of the pediatric facial bone fracture is critical in the facial bone development. This study characterizes the surgically treated patient population suffering from facial bone fractures by the use of current data from a large series consisting of 201 cases. The data was gathered through a retrospective chart review of patients surgically treated for facial bone fractures at the department of plastic and reconstructive surgery, Sanggye Paik hospital, Inje university medical center, collected over 10-years period from January, 1993 to December, 2002. Data regarding patient demographics(age, sex), seasonal distribution, location of fractures, and the causes of injury with admission periods, were collected. In total, there were 201cases of pediatric facial bone fractures. Male patients outnumbered female patients by a 5.48: 1 ratio and were found to engage in a wider range of behaviors that resulted in facial bone fractures. Physical violence was the leading cause of pediatric facial bone fractures(27.9%), followed by sports-related mechanisms (22.9%) and falling down(17.9%). The most prevalent age group was 11-15 years-old(71.1%) and there was a 14.3% prevalence in March. Among the location of fractures, the nasal bone was the most prevalent, accounting for 82.3% of injuries, followed by the orbit(9.95%), and the mandible fractures(7.5%). Most patients(59.7%) were treated within 6-9 days after trauma and the mean hospitalization period was 8-11 days. We should follow up the surgically treated patients, and they will be further evaluated about postoperative sequele and effect on the facial bone development. These studies demonstrate differences in the demographics and clinical presentation that, if applied to patients, will enable a more accurate diagnosis and proper management.

Purpose: This study was designed to compare the wound healing effect of silk fibroin, alginate and fibroin/ alginate blend sponge with clinically used Nu gauze in a rat skin defect model.Methods: Two full thickness excisions were made on the back of Sprague-Dawley rat. The excised wound was covered with either of the silk fibroin(SF), alginate (SA), or fibroin/alginate blend sponge(SF/SA). On the postoperative days of 3, 7, 10 and 14, the wound area was calculated by image analysis software. At the same time, a skin wound tissue was biopsied.Results: Healing time 50% (HT50) of SF/SA sponge treated group was dramatically reduced as compared with that of control treatment. We also found that the HT50 of SF/SA sponge was significantly decreased as compared with either those of SF or SA treatment. Furthermore, SF/SA treatment significantly increased the size of epithelialization and collagen deposition as well as the number of PCNA positive cells on epidermal basement membrane as comapred with those of control treatment.Conclusion: Our results suggest that the wound healing effect of SF/SA blend sponge is the best among other treatments including SF and SA during the whole wound healing period.
