One of the systematic attempts for technological forecasting is Delphi Method that externalizes and manipulates unformalized experts opinion in a particular problem or subject. It has, however, a critical shortcoming that it can not reflect the degree of interaction that exists among forecast events or subject. Gordon and Hayward(1969) criticize that when the forecast events are strongly interrelated, a totally unrealistic consensus may result. They proposed a new forecasting method that considers the interaction of events, that is, Cross Impact Analysis (CIA). A number of related models have been developed after them. In this study, we examine a variety of research results related to CIA obtained by literature survey and propose the limitation and future research direction. This analysis would be expected to help us to create a strategic scenario on future technology development at the government and firm level.

The aim of this paper is to analyse the impacts of R&D cooperation and obstacles to technological innovation on the innovation failure of the Korean manufacturing firms. Two hierarchical regression models including interaction variables are employed for the analysis. Some interesting findings are: first, almost all the obstacles have positive and significant effects on the failure. Second, R&D cooperation positively or negatively moderates the impact of obstacles to technological innovation on the innovation failure, although R&D cooperation itself is not directly related to the failure. Third, the interaction effects between the cooperation and the obstacles influence the failure in various manners. This study is expected to help manufacturing firms which are under unfavourable environments to formulate their cooperation strategies successfully based on what they learn from the failure.

Ubiquitous interaction in a pervasive environment is the main attribute of smart spaces. Pervasive systems are weaving themselves in our daily life, making it possible to collect user information invisibly, in an unobtrusive manner by known and even unknown parties. Huge number of interactions between users and pervasive devices necessitate a comprehensive trust model which unifies different trust factors like context, recommendation, and history to calculate the trust level of each party precisely. Trusted computing enables effective solutions to verify the trustworthiness of computing platforms. In this paper, we elaborate Unified Trust Model (UTM) which calculates entity's trustworthiness based on history, recommendation, context and platform integrity measurement, and formally use these factors in trustworthiness calculation. We evaluate UTM behaviour by simulating in different scenario experiments using a Trust and Reputation Models Simulator for Wireless Sensor Networks. We show that UTM offers responsive behaviour and can be used effectively in the low interaction environments.

World health organization has recently published a strategic plan for the development and promotion of traditional system of medicine. Herbal pathies especially Unani and Ayurvedic systems of medicines have great scope in this aspect. But, there are several problems with these pathies in the current era, as the way of research and identification is still on classical system. The correct identification of medicinal plant is one of the major problems in both the system. This should be corrected with the modern tools and techniques. The various types of data including recent discoveries, economical growth, ethnobotanical literature and extremely rapid increase in herbal journals and books have emerged great scope for these pathies. At the same time several challenges and threats are present including herb-drug interaction, false reports, toxicity studies etc. In this review paper, opportunities, threats, and researches to be focused will be discussed.

The purpose of this paper was to examine various aspects of meaning negotiation process in online chatting. Korean college students were asked to engage in chatting on the Internet over the course of a semester-long period, and chatting transcripts were analyzed in terms of sources of communication breakdown, signals to indicate communication breakdown, strategies to overcome communication breakdown, and ways of closing meaning negotiation. According to the findings of the study, lack of background knowledge and incoherent string of sentences in text were two major barriers creating communication problems. Subjects were able to use signals to indicate their communication difficulties, and overcome them by using different strategies. In doing so, however, they were found to suffer a narrow range of signals and strategies, which showed their limited communicative ability in the management of interaction, and indicated a clear, strong need for an extension of discourse and strategic competences of Korean students for more effective and smoother transition of message in everyday interaction.

The aim of this study is to formulate a trust-based business model of Internet services in so called the "trust economy." For it, firstly concepts of trust and trust economy are discussed. Then, we present previous literatures' review of trust in social science prism and trust economy in economic prism. This study classified the literatures' stances with two viewpoints of the 'system' and the 'user'. With this backdrop, we discuss three contradictory stances: Internal optimization vs. external interaction, personal data control vs. orchestration, and end-user vs. ecosystem value. In the result, we formulate a trust-based business model framework with three trust issues in user perspective and suggests three strategic directions related three issues along with representative use cases.

The main purpose of this study is to understand how the characteristics of social network services' social group can impact customer satisfaction, trust and repurchase intention. For this, this study extracts five social group factors(word of mouth effect, social interaction, collectivism, variety seeking, information seeking) based on relevant literature reviews. In addition, the study examines the moderating effects of utilitarian value on the relationships between customer satisfaction and trust and intention to repurchase. The proposed model of this study is empirically tested using survey data collected from 220 social commerce users. The results indicated that social group factors except social interaction were positively related to customer satisfaction. In addition, social group factors except social interaction and information seeking were positively related to trust. The results also showed that customer satisfaction and trust had a significant influence on intention to repurchase. The moderating effects of utilitarian value also was significant. The results of this study presented the strategic implications for social commerce firms.
