After Yahoo Korea opened up the Internet portal market in Korea in 1997, the Korean portal market has experienced fierce competition in the beginning of 2000s. After that period, however, Korean portal market looks relatively stable with top five rankers forming oligopoly and shows that Arthur's claim of network externalities can be applied to the portal industry. In this paper, based on case study of the Korean portals we empirically examined how portals have developed and evolved. In this course, we also investigated the sources of portal's competitiveness. The findings of the research suggest that portals develop and evolve through the reflexive four stages in which they compete over different goals: 1) service quality, 2) critical mass of customers, 3) interpersonal interactivity, and 4) innovative service. According to this framework of portal's evolution, we show that top ranking portals in the present have succeeded in accomplishing the goals of each stage.

This study examined relationship of effect between the characteristics of specialized portal and two branch dimension(cognitive and emotional e-trust) of e-trust on the specialized portal web-site. The characteristics of specialized portal web-site composed the guarantee factor, the structural factor, information factor, the entertainment factor and the flow factor by prior research. The model of e-trust strategy for specialized portal web-site is tested here using data from 122 samples. Result of factor and regression analysis show that the hypothesized relationships are significant. In examining the relationships of the factors in the study, the guarantee, structural and information fact effect on building of cognitive e-Trust. Second, the entertainment and flow factor effect on emotional e- Trust. Third, the cognitive and emotional e- Trust effect on the satisfaction of e-Service users. As these results, this study found out difference paths of e-Trust which effect on the satisfaction of e-Service by cognitive and emotional e- Trust approaches to the specialized portal web - sites.

Purpose: To evaluate the effect of portal hypertension on the tumor recurrence in patients with hepatocellular carcinoma (HCC) and without hepatic decompression following radiofrequency ablation (RFA). Materials and Methods: Treatment-naïve HCC patients within the Milan criteria and with Child-Pugh class A were included in this study, who had performed RFA in our hospital between January 2010 and March 2017. Univariate and multivariate analyses using the Cox proportional hazard model were performed to find the predictors of local or distant tumor recurrence. Results: Overall, 178 patients were included in this study. Median follow-up period was 40.2 months. The difference in the local tumor progression rates depending on the absence or presence of portal hypertension was not statistically significant (p = 0.195). The 1-, 3-, and 5-year distant intrahepatic tumor spread rates were 6.6%, 29.5%, and 537% in patients without portal hypertension, and 23.4%, 51.9%, and 63.6% in patients with portal hypertension, respectively. The difference was statistically significant (p = 0.011). Univariate and multivariate analysis showed that portal hypertension was an independent predictor for distant intrahepatic tumor spread (p = 0.008). Conclusion: For HCC patients with Child-Pugh class A, portal hypertension adversely affected distant intrahepatic tumor progression.
