한국 대학의 글로벌화를 위해서는 무엇보다도 우수한 CEO적 인사를 장기간 대학총장으로 재임토록 하면서, 학내외의 각종 난관을 극복하고 정부 및 사회 일반으로부터 필요로 하는 지원을 얻어낼 수 있어야 한다. 세계 명문대학의 경우처럼 한 대학에 장기간 재직하면서 소속 대학은 물론 고등교육 전체에 큰 기여를 할 수 있는 총장의 출현이 필요하다. 정부의 대학지원정책은 이를 보장할 수 있는데 초점이 맞춰져야 한다.

Jaundice is not uncommonly found as a symptom of hepatocellular carcinoma, particularly in the later stage due to the infiltrating hepatoma or to underlying cirrhosis. It is rare, however, for obstructive jaundice to occur initially and as a presenting symptom secondary to complete obstruction due to the hepatocellular carcinoma in the extrahepatic bile duct. Recently we have had the opportunity to experience three cases with hepatocellular carcinoma in whom jaundice was caused by extrahepatic biliary obstruction. The patients were presented with recurrent and progressive jaundice with or without right upper abdominal pain at admission. All of the three cases had underlying liver cirrhosis with hep- atosplenomegaly on examination with abdominal ultrasonogram and liver scan. ERC was performed in first two cases and showed smooth well defined filling defect in distal common bile duct with accompanying dilatation in one case and well defined filling defect adherant to common hepatic duct in another case. At operation, no tumor was found grossly on the surface of the cirrhotic liver in all cases. The common bile duct was explorated and multiple irregularly shaped yellowish soft tissue (chicken fat) and blood clots were evacuated, These materials revealed pathologically well differentiated hepatocellular carcinoma in all the cases. Abdominal ultrasonogram and ERC of this rare manifestation of hepatocellular carcinoma will help to establish diagnosis before surgery. But because these methods have diagnostic limitation, it is worthwhile to explorate this lesion and any material or hemobilia from the lesion should be confirmed pathologically. Therefore the authors wish to emphasize that the physician should be aware of the presentation with obstructive jaundice including both in intraluminal and extraluminal obstruction as a mechanical complication of hepatocellular carcinoma, especially with underlying liver cirrhosis.

To study the mechanisms of and conditions for adipogenesis, an accurate in situ observation tool is necessary to monitor the quantity of intracellular neutral lipids in differentiating preadipocytes. Although conventional fluorescence intensity imaging is a powerful tool for observing the formation and growth of an individual lipid droplet, it suffers from photobleaching and ambiguous autofluorescence or background signals from cells. In this paper, we present a fluorescence lifetime imaging microscopy (FLIM) technique that has the potential to quantify the ratio of neutral to polar lipids in a cell. Measurement of time-lapse FLIM images of differentiating 3T3-L1 cells that contained the Nile Red (NR) probe showed that the average lifetime of NR decreased from 4 ns in preadipocytes to 3 ns in fully differentiated adipocytes after 10 days of differentiation. This large change in the lifetime of NR can be used to monitor the early stages of adipogenesis, even when the lipid droplet is too small to be identified with a conventional microscope.

The purpose of this study is to investigate the relationship between the subjective well-being and the continuance intention by the heuristic decision-making of consumers who purchase maturity high-tech products (smart-phones and tablet PCs). The use of heuristics and selection factors consisted of personal factors (shopping tendency, knowledge, experience), product factors (brands, attributes, symbolism), environmental factors (overload of alternative choices, time constraints), and subjective well-being was divided into two dimension such as life satisfaction and emotional well-being. A total of 245 questionnaires were collected from JeJu consumers who has experience using smart-phones and tablet pc. As a structural equation model result, Other factors except environmental factors showed a significant effect on subjective well-being, and subjective well-being had a significant effect on continuance intention. These results suggest that the companies is to create a platform that can provide detailed information about the product and a positive experience so that heuristic decision-making can increase satisfaction.
