Green credit card is the card service to revitalize the eco-friendly life of the people, offering a variety of benefits to card users for supporting environment. The present research aims to examine the effect of individuals' regulatory focus (promotion focus vs. prevention focus) on their ethical behavior in the context of green credit/debit card services. This research examines whether green credit/debit card users behave ethically according to their regulatory focus. The results indicate that green credit/debit card users with a prevention focus are more likely to behave ethically compared to those with a promotion focus. The findings imply that regulatory focus may be an effective marketing and segmentation tool in facilitating individuals' ethical behavior.

Purpose - In recent years, many companies include franchises have acquire customers by making an online stores and they are carrying out permission marketing activities with e-mail and SMS. Permission marketing requires voluntary customer approval for receiving commercial messages such as cross-selling and upselling. Therefore, it is necessary for the business to induce the customer's acceptance. The purpose of this study is to examine which type of different messages can affect higher in consumer persuasion. Thus, we investigated the impact of descriptive norm message on intention of reception in an online store context, and its interaction with chronic regulatory focus. Research design, data, and methodology - This study hypothesized that the descriptive norm message would affect positive influences to consumers' intension of reception. Specially, this study inquired into whether the interaction effect between descriptive norm and regulatory focus. To verify the hypothesis, we conducted 2 × 2 between-subject factorial design with message type (general message and descriptive norm message) and regulatory focus(promotion focus and prevention focus) as independent variables. Participants of the experiment were assigned to one of 2 kind experimental situations randomly according to characteristics of message type. A total of 131 participants (descriptive norm message: 65, general message: 66) responded for this study. The data were analyzed using frequency analysis, exploratory factor analysis, and two-way ANOVA. Result - The results of the study are as follows. First, we found main effects of the descriptive norm message. The intention of reception were significantly higher in the descriptive norm message rather than general message as in previous researches. Second, interaction effect between the descriptive norm message and regulatory focus was significant. The prevention focus (vs. promotion focus) were hight in a positive behavior intention when the descriptive norm message was given. Conclusions - This study verifies the main effect and interaction effect of descriptive norm message and regulatory focus on the consumers' intention of reception in permission marketing, and persuasive message in the online store context. The results of this study will provide various advantages to companies that want to establish long lasting relationship with customers by carrying out permission marketing in the future.

The metaverse is emerging as the next digital environment for people not only to interact and collaborate with others, but also to have virtual consumption experiences. In this study, virtual fashion items for the consumer's digital self are deemed significant products with consumption value. Drawing from the regulatory focus theory, this study examines how consumers' promotion and prevention focus influence value perception and buying behaviors of virtual fashion items in the metaverse context. The data were collected through an online survey. A total of 546 consumers in their twenties who are aware of the metaverse responded to a self-administered questionnaire. The results showed that promotion focus influenced all the perceived consumption values of virtual fashion items such as the economic, visual authority, hedonic, and social value, whereas prevention focus influenced only the visual authority value. Visual authority value negatively affected both purchase intention and willingness to pay premium price, while others had a positive effect. The findings provide theoretical evidence that consumers' regulatory focus is critical in buying virtual fashion items and suggest that marketers devise effective strategies to stimulate consumers' regulatory focus and to emphasize the economic, hedonic, and social value of the items in the metaverse context.

For the pervasive computing in ubiquitous environment, it is very important to manage the context model to provide pertinent context knowledge to context-aware applications. The context model should be able to support efficiently the context knowledge reusing and sharing as well as reasoning. Previous works focus mainly on the context knowledge representation scheme for reasoning. This paper proposes a context knowledge modeling scheme especially for reusing and sharing. This scheme provides well-established principles and guides for 1) context knowledge modularization and hierarchization, and for 2) context knowledge identification and organization. Once the context models are built according to the scheme, the structure of the context model and the meanings of the context knowledge elements become clear and consistent, so that context-aware applications can share and reuse the context knowledge in easy and error-reduced manner. This paper also discusses the implementation of a context model and an application for Presentation Helper scenario running on a software middleware system (CAMUS) for ubiquitous service robots which is being developed by ETRI Korea.

We review two specific risk management strategies of venture capitalists (VCs): deal syndication and domain specialization with respect to their explicit role in adjudging and managing the overall magnitude of information asymmetry risks. These are analyzed for three distinct categories of VC firms as classified by their funding stage focus (early vs. late), ownership type (foreign vs. domestic) and the human capital composition of the core VC team (entrepreneurial vs. investor). The analysis is based on both secondary data and primary data for active 72 VC firms in India. Syndication is moderately important for entrepreneurial VC firms, but not at all important for early-stage focused and foreign VC firms. This finding is distinctly different from what has been conventionally observed in the literature. Among the various arenas of domain specialization, high-technology focus is important for all segments of VC firms. In the context of investment-stage focus, foreign VC firms exhibit growth-stage specialization, while entrepreneurial VC firms concentrate on earlier investment stages.

The purpose of this paper is to investigate the phonetic characteristics of the 'focus' phrases associated with the particle '-man' in Korean. The particle '-man' is a bound morpheme which, like other postpositions such as the subject marker '-ka' and the object marker '-lil', the so-called 'case markers' in Korean, typically attaches to a noun (phrase). The semantics of '-man' roughly corresponds to that of only, its counterpart in English, and is thus classified as a 'delimiter' (Yang 1973). It is assumed in this paper that '-man', like only in English, should have a 'focus' associated with it (von Stechow 1991, Rooth 1992). In general, '-man' attached phrases get the focus, but sometimes the association is not clear-cut, especially in the cases of emphatic use of '-man' or when the context strongly favors other phrase as the focus (Choe 1996). In this paper, we compare the phonetic characteristics of the '-man' marked phrases with those to which '-ka'/'-lil' is attached, and conclude that the focused '-man' phrases show higher fundamental frequencies than their equally focused 'case' -marked counterparts. However, when the context clearly forces the focus to fall on phrases other than the '-man' or '-ka'/'-lil' attached ones, there is no meaningful difference in fundamental frequency between the '-man' and '-ka'/'-lil' attached phrases. We also compare the phonetic characteristics of the regular use of '-man' with those of the emphatic '-man'. According to our experiments, the emphatic '-man' does not bring forth its phonetic effects, namely, higher fundamental frequencies, on the' -man' attached words or phrases but rather in various other ways such as higher fundamental frequencies in '-man', lengthening of the following word-initial syllable, or the inclusion of the following word in the same accentual phrase. Finally, it is claimed that '-man' associated focus phenomena, especially the emphatic use of '-man', show some typical acoustic characteristics of the other well-known focus phenomena, namely, wh-interrogatives.

The performance of smartphone applications are usually constrained in user interactions due to resource limitation and it promises great opportunities to improve the performance by exploring the smartphone built-in and embedded sensing techniques. However, heterogeneity in techniques, semantic gap between sensor data and usable context, and complexity of contextual situations keep the techniques from seamless integration. Relevant studies mainly focus on feasibility demonstration of emerging sensing techniques, which rarely address both general architectures and comprehensive technical solutions. Based on a proposed functional model, this investigation provides a general architecture to deal with the dynamic context for context-aware automation and decision support. In order to take advantage of the built-in sensors to improve the performance of mobile applications, an ontology-based method is employed for context modelling, linguistic variables are used for heterogeneous context presentation, and semantic distance-based rule matching is employed to customise functions to the contextual situations. A case study on mobile application authentication is conducted with smartphone built-in hardware modules. The results demonstrate the feasibility of the proposed solutions and their effectiveness in improving operational efficiency.
