In this paper, we suggest a visual language supporting collaboration with functional attributes. The visual language is a set of visual sentences that consist of object icons and operators. The object icon is a user who participates in collaboration. And, the operator means interactive relations between users according to a point of collaborative time. The functional attributes that support various computing orders provide flexibility of interactive relations on collaboration. Also, using representation both synchronous and asynchronous relations in collaboration, the visual language supports efficiently collaboration than conventional visual languages. And, functional attributes of visual sentences are analyzed using $\lambda$ expressions.

The purpose of this study was to examine differences in motivation of the tourists, who visited the Daegu Ole Palgong mountain courses, according to the slow tourism tourists' demographic characteristics and use-behavior, and to examine the relationships between motivation and the degree of satisfaction of tourists and behavioral intention. Also, it was to present motivations and characteristics of slow tourism tourists and the accompanying managerial implications. In order to achieve this research purpose, a survey was conducted from May 8, 2010 to May 23, 2010 on the tourists who visited Daegu Ole Palgong mountain courses. The results of testing the hypotheses through empirical analysis were as follows. First, differences in motivations according to demographic characteristics and demographic characteristics and the use behavior of the tourists were partially adopted. Second, there were significantly positive (+) relationships between the motivations of visitors to the Daegu Ole Palgong mountain courses and the overall degree of satisfaction. Finally, the overall degree of satisfaction with the visits to Daegu Ole Palgong mountain courses had significantly positive (+) relationships with revisit intentions. These imply that it is necessary to provide differentiated strategies and programs and inducing strategies in accordance with the results presented. as well, marketing strategies to enhance the degree of satisfaction of the tourists should be considered.

The latest movement in live video streaming service is mobile personal broadcasting (MPB), which refers to consumers accessing the service through social media with mobile devices, such as smartphones and tablet PCs. This service is possible through the advancements in mobile video technology and platforms. Features such as enhanced user interaction, personalization, and real-time broadcasting, combined with a greater variety of content, have led to the development of MPB. The increase in MPB users calls for research, including that on the hedonic motivational angle. This study aims to assess MPB users' intrinsic motives through the hedonic-motivation system adoption model (HMSAM) using seven factors: joy, temporal dissociation, escapism, focused immersion, perceived ease of use, perceived usefulness and intention to watch. Survey data collected from 154 samples were analyzed with statistical techniques, such as structural equation modeling. Results showed that time dissociation, escapism, and perceived ease of use have a positive relationship with heightened enjoyment. Joy significantly affects focused immersion and intention to watch. Escapism also had a statistically significant influence on focused immersion. This study contributes to the advancement of the MPB study under the HMSAM theoretical framework and offers practical suggestions to managers to enhance MPB content viewership.

This paper conducted a survey targeting online Korean drama viewers in Vietnam and Philippines, to investigate the relationships between viewing motivations of Korean drama, general attitude toward Korean drama, and Korea's national image. Factor analyses found six viewing motivations of Korean drama, and the most powerful viewing motivation of Korean drama were entertainment/relaxation(Vietnam) and longing for actor(actress)(Philippines), respectively. In addition, two path analyses showed that viewing motivations had a significant influence on general attitude toward Korean drama. Longing for actor(actress) and entertainment/relaxation motivations were critical factors in both countries' paths, but habit motivation was negatively related to general attitude toward Korean drama. In case of Korea's national image, the results showed that the more positive general attitude toward Korean drama, the more positive images of national image. Conclusions, implications, and limitations were also discussed.
