While the use of internet is routine nowadays, users receive and share information through a variety of media. Through the use of internet, information delivery media is diversifying from traditional media of one-way communication, such as newspaper, TV, and radio, into media of two-way communication. In contrast of traditional media, blogs enable individuals to directly upload and share news, which can be considered to have a differential speed of information diffusion than news media that convey information unilaterally. Therefore this Study focused on the difference between online news and social media blogs. Moreover, there are variations in the speed of information diffusion because that information closely related to one person boosts communications between individuals. We believe that users' standard of evaluation would change based on the types of information. As well, the speed of information diffusion would change based on the level of proximity. Therefore, the purpose of this study is to examine the differences in information diffusion based on the types of media. And then information is segmentalized and an examination is done to see how information diffusion differentiates based on the types of information. This study used the Bass diffusion model, which has been frequently used because this model has higher explanatory power than other models by explaining diffusion of market through innovation effect and imitation effect. Also this model has been applied a lot in other information diffusion related studies. The Bass diffusion model includes an innovation effect and an imitation effect. Innovation effect measures the early-stage impact, while the imitation effect measures the impact of word of mouth at the later stage. According to Mahajan et al. (2000), Innovation effect is emphasized by usefulness and ease-of-use, as well Imitation effect is emphasized by subjective norm and word-of-mouth. Also, according to Lee et al. (2011), Innovation effect is emphasized by mass communication. According to Moore and Benbasat (1996), Innovation effect is emphasized by relative advantage. Because Imitation effect is adopted by within-group influences and Innovation effects is adopted by product's or service's innovation. Therefore, ours study compared online news and social media blogs to examine the differences between media. We also choose different types of information including entertainment related information "Psy Gentelman", Current affair news "Earthquake in Sichuan, China", and product related information "Galaxy S4" in order to examine the variations on information diffusion. We considered that users' information proximity alters based on the types of information. Hence, we chose the three types of information mentioned above, which have different level of proximity from users' standpoint, in order to examine the flow of information diffusion. The first conclusion of this study is that different media has similar effect on information diffusion, even the types of media of information provider are different. Information diffusion has only been distinguished by a disparity between proximity of information. Second, information diffusions differ based on types of information. From the standpoint of users, product and entertainment related information has high imitation effect because of word of mouth. On the other hand, imitation effect dominates innovation effect on Current affair news. From the results of this study, the flow changes of information diffusion is examined and be applied to practical use. This study has some limitations, and those limitations would be able to provide opportunities and suggestions for future research. Presenting the difference of Information diffusion according to media and proximity has difficulties for generalization of theory due to small sample size. Therefore, if further studies adopt to a request for an increase of sample size and media diversity, difference of the information diffusion according to media type and information proximity could be understood more detailed.

Modern businesses are adopting new technologies to serve their markets better as well as to improve efficiency and productivity. The advertising industry has continuously experienced disruptions from the traditional channels (radio, television and print media) to new complex ones including internet, social media and mobile-based advertising. This case study focuses on proposing intelligent advertising business model in Seoul's metro network. Seoul has one of the world's busiest metro network and transports a huge number of travelers on a daily basis. The high number of travelers coupled with a well-planned metro network creates a platform where marketers can initiate engagement and interact with both customers and potential customers. In the current advertising model, advertising is on illuminated and framed posters in the stations and in-car, non-illuminated posters, and digital screens that show scheduled arrivals and departures of metros. Some stations have digital screens that show adverts but they do not have location capability. Most of the current advertising media have one key limitation: space. For posters whether illuminated or not, one space can host only one advert at a time. Empirical literatures show that there is room for improving this advertising model and eliminate the space limitation by replacing the poster adverts with digital advertising platform. This new model will not only be digital, but will also provide intelligent advertising platform that is driven by data. The digital platform will incorporate location sensing, e-commerce, and mobile platform to create new value to all stakeholders. Travel cards used in the metro will be registered and the card scanners will have a capability to capture traveler's data when travelers tap their cards. This data once analyzed will make it possible to identify different customer groups. Advertisers and marketers will then be able to target specific customer groups, customize adverts based on the targeted consumer group, and offer a wide variety of advertising formats. Format includes video, cinemagraphs, moving pictures, and animation. Different advert formats create different emotions in the customer's mind and the goal should be to use format or combination of formats that arouse the expected emotion and lead to an engagement. Combination of different formats will be more effective and this can only work in a digital platform. Adverts will be location based, ensuring that adverts will show more frequently when the metro is near the premises of an advertiser. The advertising platform will automatically detect the next station and screens inside the metro will prioritize adverts in the station where the metro will be stopping. In the mobile platform, customers who opt to receive notifications will receive them when they approach the business premises of advertiser. The mobile platform will have indoor navigation for the underground shopping malls that will allow customers to search for facilities within the mall, products they may want to buy as well as deals going on in the underground mall. To create an end-to-end solution, the mobile solution will have a capability to allow customers purchase products through their phones, get coupons for deals, and review products and shops where they have bought a product. The indoor navigation will host intelligent mobile-based advertisement and a recommendation system. The indoor navigation will have adverts such that when a customer is searching for information, the recommendation system shows adverts that are near the place traveler is searching or in the direction that the traveler is moving. These adverts will be linked to the e-commerce platform such that if a customer clicks on an advert, it leads them to the product description page. The whole system will have multi-language as well as text-to-speech capability such that both locals and tourists have no language barrier. The implications of implementing this model are varied including support for small and medium businesses operating in the underground malls, improved customer experience, new job opportunities, additional revenue to business model operator, and flexibility in advertising. The new value created will benefit all the stakeholders.

This study investigated the effects of 'K-POP' preference on purchase intention of Korean products. Especially, it revealed the mediating role between the participation intention of Korean culture event and the purchase intention of Korean products. Further, we examined the difference in the path relation according to the use-behavior of Korean wave contents. In this proposed model, we can see 'K-POP' preference had a positive effect on participation intention of Korean culture event, but it was not significant for purchase intention of common products. The participation in Korean culture event had significant effects on the purchase intention of Korean culture products and the purchase intention of common products. However, the purchase intention of Korean culture products had no significant effects on the purchase intention of common products. Thus, our finding showed that higher preference of 'K-POP' did not make cause purchase intention of common products. Further, the higher the preference of 'K-POP' was, the higher the participation intension of Korean culture event was and, as a result, the purchase intention of common products got higher. In addition, path analysis results according to the media usage behaviors show that Chinese consumer who uses the internet and has a higher preference of 'K-POP' had a positive effect on the purchase intention of common products. Furthermore, it has a positive effect on both purchase intension of Korean culture products and purchase intension of common products. In case of Chinese consumer who use the television, radio and newspapers, K-POP preference had no significant effect on the purchase intension of common products.

The continuous development of digital technology has actualized ubiquitous computing, and the environment of human life has come to face changes. Prediction of the future so that human life may be prepared can be very important. A number of predictions of ubiquitous space are presented, ranging from related professional research to mass media, However, proper analyses and understanding are required to understand ubiquitous space and apply it to design. This study seeks to understand ubiquitous space through analysis of the trend in digital technology from a new perspective, to research cases, and predict the future of ubiquitous space. Human, object, and environment have been set as basic factors as the subjects smoothly exchanges various types of information in the physical space, and the trend in digital technology is analyzed. From a human-oriented perspective, the background and development trend of digital technology has been analyzed under the theme of interaction and interlace. From an object-oriented perspective, an analysis was unfolded under the theme of products' evolvement from radios to robots. From an environment-focused perspective, an analysis has been carried out under the theme of situation recognition, intrinsic factors, and integration and connectivity. By applying the analytic results, the types of studies that predict the future of ubiquitous space and generate concepts have been classified and analyzed into three different types of studies for experiment, industry, and public. In this manner, ubiquitous space has been forecasted. This study seeks a systematic analysis of the understanding of the trends in digital technology and employs a case study of ubiquitous space based on systematic analysis. In consideration of all these, this study is expected to contribute to concept generation and development by designers.
