As a part of integrated study for technical communication between consumer and manufacturer of functional clothing, functional clothing consumers were categorized based on their perception of the functional outdoor jacket and the differences in the source of information and use of hang-tag were examined according to the groups. Questionnaire survey was conducted on 472 males and females in their 20s to 60s, who have experience of purchasing functional outdoor jackets. Perception of functional outdoor jackets was classified into four factors ('functionality', 'price', 'experience/knowledge' and 'brand/design') and the respondents were categorized into three groups according to the factors: 'unconversant/brand & design pursuing group', 'conversant/function pursuing group' and 'high-priced products preferring group'. 'Unconversant/brand & design pursuing group' was composed of high rate of office workers and students in their 20s and 30s who use internet most frequently as source of information while 'conversant/function pursuing group' was composed of high rate of professionals in their 40s and 50s who make the most frequent use of information on hang-tag. 'High-priced products preferring group', which has high rate of the elderly in their 60s and housewives, obtain their information mainly from salespersons. 'Unconversant/brand & design pursuing group' was satisfied with functional information more than other two groups and 'conversant/function pursuing group' concerned for the hang-tag and required more explanation of terminology used in hang-tag. The results effectively explained the features of consumer groups and their different responses toward the information of functional outdoor jacket.

This study analyzes appropriate government policy frameworks for promoting IPTV industry by studying the way of adoption and diffusion of IPTV services. Until recently, most researches on government policies for technology adoption have focused on the personal context. This research adopts two theories, i.e., innovation characteristics theory for personal context and implementation process theory for organizational context. It also hypothesizes that the innovation characteristics more influence on the behavioral intention for usage new media in the level of personal innovativeness is high. Moreover, in the level of expectancy for diffusion policy is high, the implementation of IPTV services more influences on the behavioral intention. The results by statistical analysis, it is found that the higher the level of personal innovativeness is, and the higher the level of expectancy for diffusion policy is, the more behavioral intention will be influenced by the characteristics of innovation and implementation of IPTV service. Thus it is important for government agencies to find the way to facilitate personal innovativeness as well as expectancy for diffusion policy.

In the rapidly expanding live-commerce market, one of the newer channels in e-commerce, consumer satisfaction appears to have plateaued. This study, therefore, aims to explore the impact of consumers' internal psychological states on the formation of service attitudes and offers practical solutions based on these findings. Whereas previous studies predominantly focused on external factors, this research examines the role of internal psychological states and perceived value in shaping consumer attitudes. Specifically, this study distinguishes between personal loneliness and social isolation, adding an altruistic dimension by incorporating interpersonal orientation, thereby setting it apart from earlier research. The focus of this study is on the psychological conditions of live-commerce consumers, investigating how factors such as loneliness, social isolation, and interpersonal orientation influence service attitudes, moderated by perceived economic value. The analysis reveals that both social isolation and interpersonal orientation significantly affect service attitudes, with social isolation exerting a stronger influence. However, no statistically significant relationship was found between loneliness and service attitude. Additionally, the effects of social isolation and interpersonal orientation on service attitudes were moderated by perceived economic value, which amplified their influence. These findings underscore the importance of incorporating consumer-centric psychological factors when developing strategies. A tailored approach that aligns with the unique characteristics of the live-commerce channel can help businesses provide customized services. This strategic approach is expected to support the development of effective operational strategies and practical solutions not only for live-commerce but also for future two-way communication channels that businesses and small enterprises may leverage.
