Choi, Eui Yul,Jeon, Yong Bae The Institute of Internet 2020 International Journal of Internet, Broadcasting an Vol.12 No.3

The purpose of this research is to organize panels centered on professional workers and experts in the sports media industry, identify structures and items of sports media commentators' attributes that conform to the present era through the collective agreement process, and evaluate the derived measures according to the scale development procedure. We would like to shed new light on the nature of commentators due to the rapid development of broadcasting technology and the emergence of new media platforms, the emergence and expansion of smart media receptors and the changing environment of modern sports broadcasting. For this purpose, a panel of experts from academia and industry related to sports management and sports media was organized and the attributes of commentators were analyzed using the Delphi method. Technology development in the sports market has created a new sports consumption environment. In these consumer environments, various environmental factors influence the consumer's consumption culture of sports consumers. For example, professional information, as well as interpretations of sports culture, history and society are becoming their share for sports commentators, and viewers are demanding more diverse characteristics from sports commentators. In this respect, the study of sports commentator attributes can be a deep understanding of the rapidly changing culture of sports consumption.

Biochemical Strain - specificity of Endosymbiotic amoeba

( Eui Yul Choi,Tae In Ahn ) 한국유전학회 1985 Genes & Genomics Vol.7 No.2

By two dimensional gel electrophoresis and cell culture at sublethal temperature, the development of strain-specificity was studied in tD strain of Amoeba proteus that had been experimentally infected by bacteria isolated from symbiotic xD strain. The infected host irreversibly lost own strain-specific protein (m.wt. 45,000, pI 5.9) and obtained obligate dependence on the infected bacteria in 20 generations. Thus the apparent characteristics of the host strain chainged like those off xD strain. In a quantitative analysis of cellular total nitrogen, protein, and ammonia by micro Kjeldahl, biuret and Folinphenol, and indo-phenol blue method, respectively the two strains showed significant difference in quantity and the ratio of the reactants. From these results, biuret reactants and/or triuret that is enclosed in crystal vacuole appear to be the possible candidates on which the symbiotic bacteria depend.

Effects of Transforming Growth Factor Beta on Cytoskeleton Structure and Extracellular Matrix in Mv1Lu Mink Epithelial Cells

Choi, Eui-Yul,Lee, Kyung-Mee,Chung, So-Young,Nham, Sang-Uk,Yie, Se-Won,Chun, Gie-Taek,Kim, Pyeung-Hyun Korean Society for Biochemistry and Molecular Biol 1996 Journal of biochemistry and molecular biology Vol.29 No.5

Previous studies have shown that transforming growth factor beta ($TGF-{\beta}$) is a potent regulator of cell growth and differentiation. To study the effects of $TGF-{\beta}$ on cell morphology and cytoskeleton reorganization, we conducted a survey using Mv1Lu mink lung epithelial cells with antibodies to cytoskeletal proteins and an extracellular matrix protein. While the untreated cells showed a cuboidal shape of typical epithelia, the Mv1Lu cells displayed a drastic shape change in the presence of $TGF-{\beta}$. This alteration was most prominent when near-confluent cells were treated with $TGF-{\beta}$. Since the morphology alteration is known to be accompanied by the reorganization of cytoskeletal proteins in other cell types, we investigated the intracellular distribution of the three major cytoskeletal structures: microfilaments, microtubules, and intermediate filaments. In the microfilament system, $TGF-{\beta}$ induced new stress fiber formation, which was caused primarily by the polymerization of cytoplasmic G-actin. However, $TGF-{\beta}$ appeared not to induce any significant changes in microtubular structures and vimentin filaments as determined by indirect fluorescence microscopy. Finally we confirmed the rapid accumulation of fibronectin by immunoblot analysis and chased the protein locations by immunofluorescence microscopy.

The purpose of this study was to analyze determinants of demand and consumption expenditure in marine sports and provide fundamental marketing information that help attract consumers and increase profits for marine sports businesses. In order to accomplish the study purposes, the study employed a survey method with a total of 303 consumers using convenient sampling method in B metropolitan city. The determinants of demand and consumption expenditure include gender, age, education, income and residence, and physical, social, cultural and psychological factors that are the motivation for marine sports participation. Dependent variables used dichotomous data as demand (participation experience or not) and consumption expenditure (more than 50,000 won or less than 50,000 won). The collected valid questionnaires were analyzed using SPSS 22.0 through descriptive statistics, factor analysis, reliability test and logistic regression analysis at the significance level of .05. Accordingly, following main findings were derived from the study. First, gender, age, income and residence were found to be the significant determinants of demand. For gender, men were 1.708 times more likely to have experience in participating in marine sports than women. For age, 30s were 3.529 times more likely to have experience in participating in marine sports than 50s or older. For income, those who have monthly income less than 3~4 million won, compared to those who have monthly income more than 5 million won, were .353 times less likely to have experience in participating in marine sports. For residence, western residents were 3.232 times more likely to have experience in participating in marine sports than eastern locals. Second, physical, social and cultural factors were found to be the significant determinants of demand. For physical factor, one unit increase in physical factor regarding participation motivation led to .634 times decrease in the probability of participating in marine sports. For social factor, one unit increase in social factor regarding participation motivation led to 1.745 times increase in the probability of participating in marine sports. For cultural factor, one unit increase in cultural factor regarding participation motivation led to 1.689 times increase in the probability of participating in marine sports. Third, age and residence were found to be the significant determinants of consumption expenditure. For age, 40s were 5.809 times more likely to spend more than 50,000 won in marine sports than 50s or older. For residence, western residents, compared to easterners, were .261 times less likely to spend more than 50,000 won in maine sports.

6세 남아가 인플루엔자 A 바이러스 감염 이후 급성 호흡부전 상태에서 내원하였다. 기관 삽관 이후 인공 호흡 및 산화 질소 공급에도 호흡성 산증 및 저산소증의 호전이 없어 내원 9시간 이후 체외막 산소 공급을 이용하여 호흡 보조를 시행하였다. 내원 12시간 이후 기관지경을 이용하여 우측 중간 기관지부터 상엽 구멍을 막고 있는 단단한 점액 마개를 제거하였다. 이후 환자는 신경계와 호흡기계 후유증 없이 퇴원하였다. 저자들은 플라스틱 기관지염으로 인한 급성 호흡 부전 상태의 환자에서 신속한 체외막 산소 공급 및 기관지경술의 처치를 시행함으로써 후유증 없이 치료한 사례를 보고한다. A 6-year-old boy with underlying hemolytic anemia of unknown etiology, atopic dermatitis, and recurrent urticaria visited our hospital because of acute respiratory failure induced by influenza A. Despite mechanical ventilation after endotracheal intubation along with inhalation of nitric oxide, respiratory acidosis and hypoxemia persisted. Veno-venous extracorporeal membrane oxygenation (VV ECMO) insertion was performed to provide respiratory support. After performing flexible bronchoscopy, we found that thick mucus plugs were obstructing the right bronchus intermedius and the upper lobe orifice. After bronchial washing and removal of the plugs, we were able to wean the patient off VV ECMO and transfer him to the general ward. He was discharged without any neurologic or pulmonary sequelae.
