The research looks at the structure of the Internet backbone and air transport networks between 82 cities in 2002, using Internet backbone bandwidth and air passenger traffic data. Centrality measures on individual city's hierarchy in the Internet and in the air traffic networks were significantly correlated, with London in the most dominant position in both networks. A quadratic assignment procedure (QAP) showed a structural equivalence between two systems. The division and membership of the clusters in both networks also showed similarity; both networks had a strongly cohesive North American‐European cluster with the London‐New York dyad as the strongest linkage in the global flow of information and people. These findings suggest that current trends in Internet infrastructure concentration reproduce and maintain global inequality and hierarchy among world cities.

This paper describes the structure of international Internet traffic based on data obtained from the Organization for Economic Co-operation and Development for July, 1998. It also describes the relationship between the structure of the Internet and international telecommunications, as well as telephone rates, language, physical location, trade blocs, international migration, student flows, and science and structural asynchrony. The results indicate that the structure of the Internet is significantly related to the structure of the international telecommunications, trade, science and student flow networks, as well language and asynchrony. In combination, only telecommunications, trade, science and asynchrony were significant, accounting for 49. 7% of the variance in the structure of the Internet.

This study examines characteristics of sports movies between Korea and the U.S. Especially, this paper focuses on three different characteristics including structural, internal characteristics and performance of sports movies. The major results are as follows: firstly, there were similarities between two countries in terms of opening year, genre, classification but movie subjects. More specifically, movie opening years were not related to global sports events. In addition, most sports movies were mainly produced by human genre and all age movie classification. However, in terms of sports subjects, although Korean movies were constructed by baseball game, the U.S. movies were based on football game. Secondly, there were also similarities between both sports movies in terms of external characteristics such as gender difference of hero or heroine, internal story structure and their story sources. Most of sports movies have used real stories as movie story. Finally, although many of the U.S. sports movies recorded the high degree of expenditures, three movies recorded the high degree of movie consumption.

This study examines determinants of user immersion for Korean drama and entertainment genre programs among Chinese students in Korea. The major results are as follows: firstly, user immersion for entertainment genre was more greater than that of drama genre. Although drama was tended to evaluated based on star appearance and narrative structure, entertainment program was favored by its pleasure and vividness. Secondly, there were gender differences for entertainment and drama genre programs between male and female respondents. Also, there was a correlation between drama immersion and duration of stay. Thirdly, although determinants of drama immersion were program characteristics, duration of stay and drama preference, those of entertainment immersion were program characteristics, appearance of star players and entertainment preference.
