The study examines how stressful life experiences and negative affective conditions influence refugees' information seeking and uses. Fifty-five North Korean refugees living in South Korea were invited to participate in a survey to determine their level of PTSD and to investigate the relationship between activeness in information-seeking and their negative affect. Seven subjects with severe PTSD symptoms participated in an in-depth interview to describe their information practices in daily life contexts. The study found that participants with higher levels of PTSD tended to seek information more passively than those with lower levels of PTSD. Almost all refugees were unable to recognize their information needs clearly but some subjects stated latent socio-affective needs and financial needs. Most refugees avoided seeking information and learned information through interpersonal sources-staffs in the Hana Refugee Center and volunteers in local community churches-and mass media. Some unique social phenomena were discovered in North Korean refugees' information world and the emergent features were discussed. On the basis of the findings, some practical approaches for improving refugees' information world were also suggested.

Purpose: This study points out that psychological marketing practice can align to narcissism among women through showing urgency and scarcity. While women are competitive, jealous, and attention seeking, marketers can offer limited-time offers to increase the urge of customers to purchase. Research design, data, and methodology: To conduct a content analysis, the present author obtained data from various databases such as ABI/INFORM, EBSCO/ EBSCO, ProQuest, and EBSCO. Ultimately, this study investigated both latent and manifest themes of narcissism and psychological marketing concepts to find solutions that leaders can use to initiate change in organizations. Results: The current study suggests that narcissistic women insist on having the best things but still have the inability to acknowledge other people's feelings. Therefore, psychological marketing can utilize such traits to ensure that the quality of their commodities matches their promises during marketing and that their customer's needs are not infringed at the expense of another customer's needs Conclusions: One of the implications of narcissism in marketing provides is that brands can easily gravitate towards litigations especially amidst unhealthy competitions. In the process of getting customers to acknowledge another brand as a better option, the competition may stir corporate conflict.

Nowadays, users' reviews and feedback on e-commerce sites stored in text create a huge source of information for analyzing customers' experience with goods and services provided by a business. In other words, collecting and analyzing this information is necessary to better understand customer needs. In this study, we first collected a corpus with 99,322 customers' comments and opinions in English. From this corpus we chose the best number of topics (K) using Perplexity and Coherence Score measurements as the input parameters for the model. Finally, we conducted an experiment using the latent Dirichlet allocation (LDA) topic model with K coefficients to explore the topic. The model results found hidden topics and keyword sets with high probability that are interesting to users. The application of empirical results from the model will support decision-making to help businesses improve products and services as well as business management and development in the field of hotel services.

Objective: This study was conducted to investigate the potential of sematic network analysis for design research. Background: As HCD (Human-Centered Design) was emphasized, lots of design research methodologies were developed and used in order to find user needs. However, it is still difficult to discover users' latent needs. This study suggests the semantic network analysis as a complementary means for design research, and proved its potential through the practical application, which compares multi-screen purchase and usage behaviors between America and China. Method: We conducted an in-depth interview with 32 consumers from USA and China, and analyzed interview texts through semantic network analysis. Cross cultural differences in purchase and usage behaviors were investigated, based on measuring centrality and community modularity of devices, functions, key buying factors and brands. Results: Americans use more services and functions in the multi-screen environment, compared to Chinese. As a device substitutes other devices, traditional boundaries of the devices are disappearing in the USA. Americans consider function to recall Apple, but Chinese consider function, design and brand to recall Apple, Sony and Samsung as an important brand at the time of their purchase. Conclusion: This study shows the potential of semantic network analysis for design research through the practical application. Semantic network analysis presents how the concepts regarding a theme are structured in the cognitive map of users with visual images and quantitative data. Therefore, it can complement the qualitative analysis of the existing design research. Application: As the design environment becomes more and more complicated like multi-screen environment, semantic network analysis, which is able to provide design insights in the intuitive and holistic perspective, will be acknowledged as an effective tool for further design research.

Today, many companies realize that the effort to develop new products / services faster that customers want and continue to purchase is crucial for their survival. As the service sector is rapidly growing, one of the challenges faced by the service industries is the lack of effective methodologies for new service development. This paper proposes a systematic framework for developing new service concepts, with an emphasis on generating innovative, convergence-type service concepts from the customer‘s perspective. The framework consists of three phases-identification of customer needs (Phase I), extraction of new service opportunities (Phase II), and generation of new service concepts (Phase III). The proposed framework is demonstrated through a case study in the telecommunications industry. In the case study, a survey was conducted on ten customers to identify the latent customer needs; 61 new service opportunities were extracted; and 129 new service concepts were generated.
