Recently not only industry but also academy have shown an intense interest in social networking service. However, reckless imitation will not guarantee the successful eco-system of social networking service without rich understanding of growth driver and business model. Hence, this study aims at analyzing open platform strategy and business model conducted by a representative social networking service provider in order to provide platform operator, network operator, and portal provider with meaningful implications. Advertisers may pay great attention to social networking service because it has strong ability to provide users with spontaneous motivation to manage and update their profile, and these valuable information can be utilized for providing personalized advertisement on social networking service. As a result, one side of consumers in two side market, advertisers, tend to pay more expenditure to place advertisements. In addition, the open platform adopted by social networking service providers causes pro-sumers to participate in the eco-system, and thereby the explosive quantitative growth is realized. The fact of that this open social networking service can invade other web service area via an unified platform indicates that it may expand its service scope into a wide variety of web service areas. Hence, domestic portal services providers and network providers should consider social networking service not as one of new web services but as an disruptive service platform. Corresponding to the emergence of social networking service, especially if their business area is related to display advertising market, they should seek a way to provide social networking service access users's newly updated information and develop innovative media technologies to enter context awareness ads market.

As EU's enlargement toward Central and Eastern countries, it is expected to change of the economic activity space of EU. This paper aims to examine the changing of economic activity space of EU with a locational analysis of foreign direct investment in Central and Eastern countries. The foreign enterprises, particularly EU's firms are increasing the direct investment in the Central and Eastern countries from the middle 1990's for a raising of the efficiency of production and a prior occupation of the potential market. The foreign direct investment in Central and Eastern Europe has a tendency to concentrate in Poland, Hungary, Czech and Slovakia, which has relatively a large market, a cheap and plentiful labor, a stable political system and a positive inviting policy of foreign direct investment. And, the foreign direct investment shows a tendency to locate generally in a big city, which has a advantageous production factors by a well-developed infrastructure and a regional industrial organization, a skilled labors, a market, etc., and in a border area between East and West Europe because of a cheap and plentiful labor, a similar cultural environment and the low cost of transportation. In conclusion, as an integration of the Central and Eastern countries into EU, the capital territories of Hungary, Czech and Poland, and the border area between East and West Europe is becoming a new economic activity space of EU with a location of foreign direct investment. And. the Baltic zone is also expect to become a new economic activity space according to the augmentation of exchanges and direct investment inter near countries.

This study aims to verify whether service characteristic factors of theme park, consisting of ease of access, convenience of service, diversity of events and safety of facilities have positive effect on customer satisfaction and, in turn, customer satisfaction on intention of revisit for customers. We conducted surveys on 317 customers having experiences of visiting domestic theme parks and obtained the results that three factors except ease of access have positive effect on customer satisfaction and customer satisfaction on intention of revisit. As the further analysis, we checked if customer satisfaction has positive moderating effect on the relationship between four service characteristic factors and intention of revisit. We found that diversity of events and safety of facilities have full moderating effect and convenience of service partial moderating effect, while ease of access has not that effect, which offer implication that theme parks have to make more effort and investments related to diversity of events and safety of facilities to increase possibility of customer revisit.

Information sharing behavior in the Internet has raised much interest. Recently, social network sites provide a new information sharing channel for the users who want to connect with others based on common social background or tastes. Especially, we focus that a social network site becomes one of major routes for information sharing about socially influential issues. Therefore, studying how information is diffused via a social network site may give theoretically, practically significant implication. Based on the assertion, we investigated user's behavior to mediate other user's information messages. We define information mediating behavior as concurrent actions of filtering and distributing behavior of the digital content that is originated from one of the connected users. In this study, we intended to understand the effects of information mediating behavior, and tried to understand characteristics of re-mediating of previously mediated information. Using an agent-based simulation model, we found that information mediating behavior increased the extent of information diffusion significantly. In addition, even a small degree of mediating probability could boost up the level of information diffusion in the case of a re-mediating condition. We believe that those findings provide remarkable insight of research and business application on both of information sharing and diffusion in a social network site.

This study analyzes the process of growth of Busan from a fishing village to the capital city of South Gyeongsang Province and the central city of transportation and commerce, and an industry with records. The results of the analysis are as follows: after the port opened in 1876, there has been a decline in settlement spaces in Dongnae; on the other hand, there has been an increase in migration spaces around the port of Busan. Waegwan (倭館) nearby Yongdusan Mountain (龍頭山) was changed to the Japanese concession; thus, the number of Japanese moving into Busan had rapidly increased. As a result, the Japanese government carried out reclamation work for securing available lands for the construction of port facilities and other facilities. The Japanese government built public offices and houses, as well as production facilities for daily necessities around the port of Busan. The opening of the Seoul Busan railway (京釜線) and the cross-channel liner between Busan and Shimonoseki (釜關連絡船) led to the growth of Busan and the development of its status. At this time, as the main industry of Busan was trade, Busan had grown as a commercial city. As Busan had grown as a central city of transportation and commerce, the provincial government building of Gyeongsangnam-do (慶尙南道) moved to Busan. Thus, Busan became the central city of local politics and administration. After the Land Survey Project, a large scale of farmers were recruited for low-wage work in the new port. Because of the abolition of the corporation law, Japanese capitalists moved into their colony in Busan. There, large-scale factories, such as the Joseon cotton textile factory, were established. Through this process, the locality of Busan was changed from a fishing village to a commercial city and, finally, to a city of commerce and industry.

Display technology has recently made enormous progress. In particular, display companies are competing each other to develop flexible display. Curved display, as a precursor of flexible display, are now used for smart phones and TVs. Curved monitors have been just introduced in the market, and are used for office work or entertainment. The aim of the current study was to investigate whether the curvature of a 42" multi-monitor affects postural control when it is used for entertainment purpose. The current study used two curvature levels (flat and 600mm). Ten college students [mean(SD) age = 20.9 (1.5)] with at least 20/25 visual acuity, and without color blindness and musculoskeletal disorders participated in this study. In a typical VDT environment, each participant played a car racing video game using a steering wheel and pedals for 30 minutes at each curvature level. During the video game, a pressure mat on the seat pan measured the participant's COP (Center of Pressure), and from which four measures (Mean Velocity, Median Power Frequency, Root-Mean-Square Distance, and 95% Confidence Ellipse Area) were derived. A larger AP (Anterior-Posterior) RMS distance was observed in the flat condition, indicating more forward-backward upper body movements. It can be partly due to more variability in visual distance across display, and hence longer ocular accommodation time in the case of the flat display. In addition, a different level of presence or attention between two curvature conditions can lead to such a difference. Any potential effect of such a behavioral change by display curvature on musculoskeletal disorders should be further investigated.

For a long time, Disney has made animations including world views such as family-focused, conservative ideology, happy ending, etc. for families. Periodical situation and spectators' demands have been changed little by little, but Disney is still a company who is the most successful both nominally and virtually in animation industry. For the secrets of their success, there is fantasy world of fabricated animation, thoroughly organized story and image. When spectators watch animations, their sufficient immersion in the fantasy is to let them forget realities. In the introduction of Disney animations, spectators turn off the switch of realities and turn on the switch of fantasy world through the procedure to recognize and confirm virtual world sufficiently. In the switch of the introduction used frequently by Disney, there are four methods. First is to start while opening the cover of storybook. Second is to start while storyteller gives a talk directly. Third is to start with live action film and continue to animation. Fourth is musical method. Those four switches play a role of the gate which distinguishes spectators' realities from Disney's fantasy clearly. The process makes an opportunity to set spectators who feel uneasy due to the vague boundary between realities and fantasy at ease and let them immerse in animation sufficiently with mind at ease.

Internet is no longer a network for special communities but became a global means of communication infrastructure for everyday life. People are exchanging their personal messages using e-mails, students are getting their educational aids through the web, people are buying a variety of goods from cyber shopping malls, and companies are conducting their businesses over the Internet. Recently, such an explosive growth of the traffic in the Internet raised a big concern on how to accommodate ever-changing user's needs in terms of an amount of the traffic, characteristics of the traffic, and various service quality requirements, Over provisioning can be a simple solution but it is too expensive and inefficient. Thus many new technologies to solve this very difficult puzzle have bcen introduced recently, Any single solution, however, can be insufficient and a carefully designed architecture, which integrates a group of solutions, is required. In this paper, we propose a policy-based Internet QoS provisioning, traffic engineering and perfonnance management system as our solution to this problem. Our integrated management QoS solution can provide highly responsive flow-through service provisioning, more realistic service and resource policy control based on the real network performance information, and centralized control of traffic engineering for heterogeneous networks.

The Korean government designated 10 innovation cities throughout the country in 2005 in order to resolve concentration on the capital region and to promote balanced development of localities. An innovation city is a future-type city equipped with environment for innovation and high-quality settlement environment in terms of residence, education and culture by accommodating public institutions and facilitating close cooperation among companies, universities and research institutes. Thus, for the early settlement and activation of innovation cities, this study suggested a plan to operate the current innovation city business centers from a mid- and long-term viewpoint rather than for a limited time. Through this study, we attempt to establish the roles of the centers so that they can play central roles in the move of public institutions, the development of industry-university-research institute clusters, the creation of innovations, and the spread of innovations, which are the goals of the development of public institutions, after the sites have been prepared.

This paper aims to analyze factors affecting technology transfer performance according to different types of Korean universities and to conduct the research for the channel and extent of impact between these factors, utilizing 5 - year data for the technology transfers of 110 universities based on the survey by National Research Foundation of Korea. According to the analysis, incentive for researchers is the most crucial factor in local universities and small & medium-sized private universities located in the capital area. And numerical value of intellectual property rights owned by university is the key factor in universities specializing in science & engineering / industry. Also, Big-sized universities are heavily affected by the number of full-time faculty. In case of private universities, government subsidy relating to patents is critical factor for technology transfer performance. The mean value of all variables is a lot higher in participant universities than non-participant ones in CK(Connect Korea) project. In summary, it is suggested that steady financial support provided by the government is required and that mutual cooperation for industry-university-government is also needed for the commercialization of the technologies held by universities.
