본 연구에서는 인뇨에서 분리 정제한 urokinase와 유전자 재조합 CHO(Chinese Hamster Ovary) 세포 배양액으로부터 분리 정제한 pro-urokinase의 물리화학적 특성과 혈액 내에서의 효소활성을 비교 분석하였다. Two chain form인 urokinase와 single chain form인 pro-urokinase를 각각 순수 분리한 후, electrophoresis한 결과 모두 54 kd의 단일밴드를 나타냈다. 그러나 urokinase는 환원시켰을 때 33 kd과 21 kd으로 나누어짐을 확인하였으나 gel filtration결과 분자량이 54 kd 정도임을 확인되어 용액 내에서 단일분자로 존재함을 알 수 있었다. Urokinase와 pro-urokinase가 물리화학적으로 거의 동일한 구조를 가졌다는 사실은 isoelectro focusing에 의한 pI 값이 모두 8.6으로 동일하다는 점과, 아미노산 조성을 분석한 결과 동일하다는 사실로도 알 수 있었다. N-terminal 아미노산 서열을 분석한 결과, urokinase는 이중사슬구조이므로 N-terminal이 두개 존재하여 pro-urokinase의 서열(Ser-Asn-Glu-Leu-His-Gln-Val-Pro-Ser-Asn)이외에도, 159번째의 Ile다음부터 Ile-Gly-Gly-Glu-Phe-Thr-Thr-Ile-Glu가 같은 peak로 나타남을 확인하였다. 효소활성 조사결과 pro-urokinase와 urokinase는 모두 농도 의존적으로 혈전용해 활성을 보였으나, 특이하게도 짧은 반응시간동안에는 urokinase가 동일 농도 하에서 강한 활성을 보인 반면, 2시간이 지난 오랜 반응조건에서는 pro-urokinase가 혈전용해활성을 나타내었다. Fibrinogen에 대한 분해활성을 조사한 결과, urokinase는 혈장 내 fibrinogen을 상당히 손상시키지만, pro-urokinase는 거의 영향을 주지 않아 혈전선택성이 매우 좋음을 알 수 있었다.

A life-long anticoagulation for the prevention of ischemic cerebral events by thromboemboli has been conventionally introduced for the treatment of an atrial septal aneurysm. However, due to the recent decrease of the risks in the open heart surgery, the alternative therapeutic modality has been introduced for the prevention of complications of the anticoagulation. A 41-year old female with dizziness was admitted to our hospital. She was diagnosed a shaving atrial fibrillation and a cerebellar infarction, and an atrial septal aneurysm was detected by transesophagel echocardiography that was not detected by the transthoracic echocardiography. Surgery was approached to the right submammarial anterolateral thoracotomy. The atrial septal aneurysm was obliterated by a purse-string suture and plication. Surgial results were excellent with normal sinus rhythms and esthetically satisfying appearance.

1. 브레히트와 현대연극 : 브레히트 시 번역의 어려움
이승진 ( Sung Jin Lee ) 한국브레히트학회 2014 브레히트와 현대연극 Vol.0 No.30
Ein Gedicht ist ein asthetisch-architektonisches Gebilde, das nicht nur inhaltlich, sondern metrisch gebaut wird. Die Ubersetzung der Gedichte ist darum eine der schwierigsten Aufgaben. Brecht hat uber 2,300 Gedichte, die ein breites Spektrum abdecken, geschrieben. Er hat verschiedene traditionelle lyrische Formen in seine Lyrik ubernommen: Ballade, Terzine, Sonett, Epigramm sowie Choral. Metrisch hat er seine eigene gestische Rhythmik Reimlose Lyrik mit unregelmaßigen Rhythmen entwickelt. An der Aufgabe, die die Weite und Vielfalt seiner Lyrik in eine fremde Sprache zu ubersetzen, konnen die Ubersetzer verzweifeln. Um seine Gedichte trotzdem zu ubertragen, sind die Merkmale der Lyrik Brechts in Betracht zu kommen. Dieser Aufsatz analysiert die Eigentumlichkeit seiner Lyrik, die die Ubersetzung erschwert, in 7 Aspekten: die gebundene Sprache, die Bildersprache, das ``Gedicht als das Lied``, ``die Dialektik der traditionellen Form``, ``die gestische Rhythmik (Sprache)``, ``die textkritische Schwierigkeit in der Auswahl der Fassung`` sowie die pornographische Erotik.

Purpose: It is well known that respiratory viral infection has epidemiological characteristics, including season. This study aimed to investigate the patterns of the prevalence of common respiratory viruses during a period of 10 years with regard to age, sex, and season in Korean children. Methods: From June 2006 to November 2016, we obtained 11,798 specimens from patients aged less than 18 years who were ad mitted with lower respiratory infections. Ten respiratory viruses were detected using multiplex reverse transcription-polymerase chain reaction. Results: Of 11,798 specimens, at least 1 virus was detected in 4,845 (41.1%). Respiratory syncytial virus (RSV, 18.9%) was the most common virus detected, followed by human rhinovirus (HRV, 14.8%), adenovirus (9.5%), and human bocavirus (HBoV, 7.4%). The detection rate of HRV was higher in male subjects (male 60.0% vs. female 40.0%, P=0.004), but the other viruses had no significant differences with regard to sex. The subjects who were positive for RSV test were youngest (median, 10.5 months; interquartile range, 3.0-25.0 months), followed by human coronavirus (median, 13.0 months), HRV (median, 14 months), and parainfluenza (median, 14 months). HBoV was most commonly detected in spring (29.3%), enterovirus in summer (25.8%), HRV in fall (22.6%), and RSV in Oc tober and winter (22.6%). Conclusion: We found that the prevalence of respiratory viruses in Korean children during a period of 10 years was associated with age, sex, and season when the infection occurred. Further nationwide data is warranted to infer clinical implication of our results. (Allergy Asthma Respir Dis 2017;5:320-325)

S. marcescens KCTC 2172로부터 유전자 은행을 작성하여 재조합 클론 pDH3를 얻었으며, pDH3 유래의 서브클론을 작성하였다. 플라스미드 pPH4의 전염기서열 5,137 bp 영역을 결정한 결과 3개의 ORF가 있음을 확인하였다. 이들은 pst 오페론의 pstC, pstA, 및 pstB, 세 유전자를 동일 전사방향으로 코드하고 있었다. 타 세균의 유전자와 비교한 결과 S. marcescens의 pst 오페론은 pstS와 phoU가 결손되어 있다. 조절영역에는 CRP 결합영역과 pho box 서열이 존재하였다. 보고된 유전자와 상동성 조사결과, PstC 단백질은 Yersinia sp., Vibrio sp. 및 Pseudomonas sp.와는 49, 37, 33%의 상동성을, PstA 단백질은 Yersinia sp., Vibrio sp. 및 Pseudomonas sp.와 64, 51, 47%의 상동성을, PstB 단백질은 Methanocaldococcus sp., E. coli 및 Mycoplasma sp.와 60, 50, 48%의 상동성을 나타내었다. Pst 유전자들은 조절영역의 cAMP-CRP 복합체에 의해 in vivo에서 양성적으로 발현됨을 확인하였다. Pst 오페론을 포함하는 플라스미드를 도입한 대장균은 인산운송에 관여하는 능력을 확인하였다. A recombinant plasmid, pDH3, was obtained from the genomic library of Serattia marcescens KCTC 2172, and several recombinant subclones constructed from pDH3. The nucleotide sequence of a 5,137 bp segment, pPH4, was determined and three open reading frames were detected. The three ORFs encoded the phosphate specific transport (pst) operon, which was pstC, pstA, and pstB, with the same direction of transcription. Comparison of the pst operon of S. marcescens with that of other organisms revealed that the genes for pstS and phoU were missing. A potential CRP bonding site and pho box sequence was found in the upstream of the putative promoter at the regulatory region. Analysis of the nucleotide sequence showed that homology in amino acid sequences between the PstC protein and Yersinia sp., Vibrio sp., and Pseudomonas sp. were 49, 37 and 33%, respectively. The PstA protein and Yersinia sp., Vibrio sp., and Pseudomonas sp. showed homologies of 64, 51, and 47%, respectively. PstB protein and Methanocaldococcus sp., E. coli, and Mycoplasma sp. showed homologies of 60, 50, and 48%, respectively. The pst genes could be expressed in vivo and positively regulated by cAMP-CRP. The E. coli strain harboring plasmid pPH7, with pst genes, increased with the transport of phosphate.

이승진(Lee, Seung-Jin),김지태(Kim, Ji-Tae),정연성(Jung, Yeon-Sung) 한국체육과학회 2015 한국체육과학회지 Vol.24 No.4
The purpose of this study was to analyze the relationship among self-management, sports confidence, and exercise commitment of inline skate players. In order to achieve these goals, a population was selected from male and female inline skate players in teams of the middle and high schools, universities, and businesses in 16 cities and provinces who were registered with the Korea Roller Sports Federation. And a total date of 291 players were collected from the players who competed in the 34th National Male and Female Roller Tournaments according to convenient sampling method. Hypothesis test on collected data was conducted by using SPSS 20.0 and AMOS 20.0. programs. The following are the conclusions of this research. First, self-management of inline skate players had a positively (+) significant effect on sports confidence. Second, self-management of inline skate players had a positively (+) significant effect on exercise commitment. Third, sports confidence of inline skate players had a positively (+) significant effect on exercise commitment. Fourth, self-management of inline skate players had a direct influence on exercise commitment yet through the partially mediating effect of sports confidence.
