OSS(Open source software) pursues the freedom to have access to open source and offers several advantages, over the proprietary software, to enterprises. Based upon Rogers(1995)' innovation-diffusion process, we assume that attributes of innovations includes five characteristics of innovations: relative advantage, compatibility, complexity, trialability, and observability, and that firms' perceptions of these characteristics predict the rate of adoption of OSS. To test this hypothesis, we presents a survey result from 201 companies and institutions concerning the use of OSS. Statistical analysis shows that adoption is highly correlated with each of those characteristics of innovations, but the regression analysis indicates that only compatibility and observability have effects on the adoption of OSS. This implies that intrinsic value of OSS is important, but unless the appropriate service package for improving IT environment is provided, it is not easy to change the perspective of corporate customers more favorable toward OSS use. As a conclusion, the academic and practical implications are also discussed.

The purpose of this study is to search information attributes suitable for SNS and to identify the influence of individuals or groups who contribute to the creation and diffusion of information in the SNS. The researchers extracted the accuracy, two-sided information, novelty, diversity, and experiential factors that influence the acceptance and diffusion of information in the SNS, and identified the relationships among the variables, the usefulness of information and the degree of information diffusion intention. And researchers studied market maven who play the key role in creating and diffusing SNS information. A total of 600 questionnaires were collected and 549 questionnaires were used to test the research hypothesis. The results of the study are as follows. Consumers considered information, which had accuracy, two-sided, and experiential attributes, as useful. But novelty or diversity information were regarded as unuseful because of motive to avoid ambiguity. In the Market Maven Group who have the ability to acquire and edit SNS information, however, there were weak or negative causality between experience and accuracy and information usability factors. but positive causality between novelty and diversity factors of information and usability.

The rapid diffusion of using internet and technical development becomes a driving force creating and developing the industries based on internet and made up an electronic commerce market which is a new form of business market. The object of this study is the business form between the consumer and the enterprise having a rapid growth nowadays. We classified enterprises' characteristic factors in internet shopping mall into product's characteristic factors on shopping mall, characteristic factors of the system on shopping mall and characteristic factors of the interaction between customers and shopping mall in the internet shopping mall. And then we investigated how these classified characteristic factors on shopping mall could influence on customer loyalty.

Mobile banking, a type of digital convergence, has recently spread in the ubiquitous age. This study intends to identify the factors that affect the adoption of the mobile banking, which is a field similar to, but even more specialized than, the Internet banking. The results indicate that the significant factors affecting the usage of mobile banking are usefulness, service quality, and instant connectivity, while usability and social influences are not significant. These results are expected to be used for marketing the mobile banking and establishing the technological strategy by the telecommunication and banking organizations.

The purpose of this study is to investigate how the advertising campaign is spreading in social networks, and how the advertising model plays an important role in advertisement diffusion. In order to grasp the diffusion patterns of advertising, a text mining and social network analysis were conducted using the beer brand 'Kloud' as a collection keyword. After analyzing the social data for two months since the on-air of 'Good Body' advertisement, which was the first ad that "Sulhyun" appeared in. After the launch of the ad, Kloud has been mainly associated with keywords such as 'yavis & trendy style', 'beer brand', 'beer matching food', 'luxury beer drinking place', 'leisure trend', and 'SNS activity', etc. In addition, "Sul Hyun" also showed that an advertising model contributes to the spread of advertisement on social media in terms of image transition as well as brand's name and unique selling point.

In this paper, a water tank experiment using Binary Frequency Shift Keying (BFSK) method for text transmission performance by water surface fluctuation is conducted. Water surface fluctuation and delay spread which affect the channel coherence bandwidth is a limiting factor in underwater acoustic communication. The amplitude fluctuation and delay spread the smooth surface and fluctuation surface, were identified. The effective delay spread of both cases are 5ms, 4ms corresponding to the coherence bandwidth of 200Hz, 250Hz, respectively. The bit error rate of BFSK modulated text transmission is about $10^{-4}$ in less than 200bps in smooth surface but less than 250bps in fluctuation surface. Therefore, this experiment shows that the water surface fluctuation is important factor determining the performance of the underwater acoustic transmission.

일본 자동차 유통계열 구조에 변화의 조짐이 일어나고 있다. 가전 부문의 유통계열이 신유통업태의 정장이라는 외부적 요인에 의해 변화되었다면, 자동차 유통계열은 내적ㆍ외적 요인의 상호작용에 의해 그 문제점이 노정되고 있다. 내적인 요인으로는 메이커의 경직적인 도매가격 운용을 들 수 있는데, 이는 딜러 경영을 압박할 뿐만 아니라 메이커-딜러간 갈등을 야기하는 주된 요인이 되고있다. 한편 급속한 정보화는 딜러의 할인판매 경쟁만 가속시킬 뿐 유통계열의 개선에는 유용성이 없는 것으로 분석된다. 장기적으로는 자동차 유통계열의 내부적 모순이 점차 가시화되고 정보화가 확산됨으로써 정차 변화할 것으로 예상된다. 한국 국자동차기업은 이러한 유통계열의 약점을 전략적으로 이용하면서 차별화된 제품으로 승부하는 전략을 구사하는 것이 바람직할 것이다.

The purpose of the study is to identify the barriers to using mobile health applications based on the Diffusion of Innovations Theory. The study employed a purposive sampling to recruit college students who were non-adopters or rejecters. The study participants were a total of 44 students, who consist of 32 males and 12 females, and paper-based interviews were conducted. The findings of the study indicated that attributes such as relative advantages, complexity, trialability and observability were not considerable factors of impeding the adoption or continuous use of health applications, whereas relative disadvantages and compatibility were. The study suggests that health application developers and service providers minimize relative disadvantages and enhance compatibility of the innovation with consumers' life styles, rather than try to improve relative advantages and complexity, to more effectively encourage non-adopters to try and maintain using the innovation.

In this paper, we report the empirical study results theorizing IPTV user's loyalty formation process. Considering the convergent characteristics ofinnovative media and telecommunication, we employed innovation adoption and diffusion as our theoretical framework for research model development. As the purpose of this research includes verification of detail attributes of IPTV service, we formulated structural model which treats relative advantage as the second order factor, of which incorporates the seven detail attributes as the first order factors. Then, using the data collected from 250 Korean IPTV subscribers, the model is validated and relevant attributes are identified through PLS analysis. The results provide insights for future research on the adoption and diffusion of new digital convergent high-tech services.

This study analyzed the impact of various factors on the use-diffusion of smart speakers. 300 survey responses of Chinese consumers were analyzed using structured models. The results show that both autonomy and adaptability had significant impacts on perceived usefulness and perceived easy of use. Multifunctionality and ability to cooperate affected perceived usefulness, while reactivity did not affected perceived usefulness or perceived easy of use. Anthropomorphism increased perceived enjoyment. Both perceived usefulness and perceived easy of use have been identified to improve the use-diffusion of smart speakers. Perceived enjoyment enhanced the variety of use. We expect these results help understand the factors that need to be considered for the design or marketing communication of smart products.
