This study is to examine the spatial construction found in expositions in the 19^(th) century. The purpose is to understand architecture in the 19^(th) century as the origin of the modern architecture in the 20^(th) century, and to reveal the authenticity of modern spaces through spaces of expositions. Expositions in the 19^(th) century are one of the leading architectural themes in that age, Having a vast influence on entire Europe, they are new modern institutional buildings emerging with new modern technologies and culture. This study analysis expositions through three viewpoints in the modern institutional buildings which were 'time', 'threshold' and 'perception'. As a result, spatial construction in expositions were formed by things, people and space which were related to the three viewpoints. The phenomenon and the process in the spatial construction of exposition are related to the modern architecture, and also relations in the space of exposition are extended to the city and the architecture in the 20^(th) century. Therefore, the modern institutional buildings in the 19^(th) century will be studied as to reveal identity of the modern architecture and its modernity.

The biggest issue in the financial industry in recent years is PinTech. One of the earliest and fastest growing segments of FinTech is the easy payment service. The researches that are most actively carried out in various Pin-tec related studies conducted in Korea are contents related to the mobile easy payment service and the acceptance attitude of individual users. The main purpose of these studies was to intensify the intention of using mobile easy payment service or to understand what factors impede it. This study presents the perceived risk as a factor impeding the acceptance of mobile easy payment service and analyzed these models by comparing gender differences. The results of the analysis show that perceived risk has a significant effect on the usefulness of the easy payment service. However, in the case of the female group, the perceived risk has no effect on the usefulness of the easy payment service There is a cognitive difference between men and women. In addition, the results show that the ease of use does not affect acceptance intention for males, whereas the result shows that there is a difference between males and females in that the ease of use affects acceptance intention . 최근 금융산업의 가장 큰 이슈는 핀테크이며, 이중 가장 먼저 적용되고 성공적인 성장을 한 부분은 간편결제 서비스이다. 국내에서 수행되고 있는 여러 가지 핀테크 관련 연구에서도 가장 활발히 수행되고 있는 연구는 모바일 간편결제서비스와 개인 이용자의 수용태도에 관련된 내용들이다. 이들 연구들은 주로 모바일 간편 결제 서비스 이용의도를 강화시키거나 이를 저해하는 요인이 무엇인가를 파악하는 것이 주된 목적이다. 본 연구는 모바일 간편결제 서비스의 수용을 저해하는 요인으로 인지된 위험을 제시하였고, 제시된 연구모형을 성별간 차이비교를 통해 분석하였다. 분석결과 남성집단의 경우는 인지된 위험이 간편결제 서비스의 유용성에 유의한 영향을 미치는 것으로 나타났으나, 여성집단의 경우는 인지된 위험이 간편결제 서비스의 유용성에 아무런 영향을 미치는 못하는 결과를 보임으로서 남녀간의 인지차이를 보이고 있다. 이외에도 남성집단의 경우 사용편의성이 수용의도에 영향을 미치지 못하는 결과를 보이나 여성집단의 경우 사용편의성이 수용의도에 영향을 미친다는 결과를 보임으로서 성별간 차이가 존재함을 보여주고 있다.

Fetal bovine serum (FBS) is an essential element of cell growth and can also affect the viral replication. In this study, we tried to find out whether FBS concentration affects the viral infectivity titer of IHNV and IPNV. EPC cells were suspended with MEM supplemented with various concentrations of FBS (MEM0, MEM2, MEM5 and MEM10) and cultured in 96-well plate. Each virus was 10-fold diluted virus and inoculated in 96-well plate. The highest infectivity titer of IHNV was $10^{7.88}\;TCID_{50}/mL$ in 96-well plate using MEM5 and the lowest one was $10^{7.30}\;TCID_{50}/mL$ in 96-well plate using MEM10. The highest infectivity titer of IPNV was $10^{7.47}\;TCID_{50}/mL$ in 96-well plate using MEM5 and the lowest one was $10^{6.97}\;TCID_{50}/mL$ in 96-well plate using MEM10. This study showed that not only 0% FBS but 10% FBS leads low infectivity titer of IHNV and IPNV. Therefore, it is considered that the desirable concentration of FBS is 2% or 5% for measurement of infectivity titer of IHNV and IPNV.

Purpose: Colorectal cancer is believed to progress through an adenoma-carcinoma sequence. However, recent evidence increasingly supports the existence of an alternative route for colorectal carcinogenesis through a serrated adenoma, which combines the architectural features of hyperplastic polyps with the cytological features of traditional adenomas. We assessed the characteristics and the endoscopic features of serrated adenomas and compared them with those of hyperplastic polyps and traditional adenomas in Korea. Methods: The medical records of 344 consecutive patients who underwent a colonoscopic biopsy or polypectomy from January 2003 through August 2004 at Gyeongsang National University Hospital were analyzed retrospectively. Results: Serrated adenomas were seen in 12 cases (3.4%), and the most common site was the rectum (50%). Endoscopically in most cases, the serrated adenomas had small diameters (≤0.5 cm) and were single polyps. Morphologically, the serrated adenomas were flat and non- pedunculated. The coincidental rate of the carcinomas was 8.3%. Conclusions: According to this study, serrated adenomas are generally single, sessile adenomas with diameters less than 5 mm, and they are commonly observed in the left colon, especially in the rectum.
