The travel-related applications on a smartphone help tourists make a reservation before their trip conveniently; use a map, direction guidance, and translation services during the travel; evaluate and recommend travel services communicating with others after their journey. This study examines the relationships among affordances and constraints provided by the mini-program, users' perceived value, and travel-related mini-program (TRMP) usage by analyzing the structural equation modeling. An online questionnaire was developed from the available scales in the published literature. A total of 651 TRMP users responded to the survey, and 448 valid responses were included for analysis. Affordance, including physical, cognitive, sensory, and functional affordance, significantly influenced the hedonic value of TRMP; utilitarian value except for cognitive affordance. There were negative relationships between unfamiliarity and both types of value. The utilitarian and hedonic value of TRMP significantly influenced both the exploitative and explorative use of TRMP. Travel-related mobile applications are dramatically increased in the tourism field. This research sheds light on TRMP usage, as a new and smart device, from a user's perspective based on the affordance theory. This study represents a valuable direction regarding the emerging travel-related online platforms in tourism.

This study describes a set of user experience indicators developed for the evaluation of knowledge and information resource systems. The user experience perspectives had emerged as a new analysis standard in the field of information media and information service research. The study included a survey conducted to verify the derived experience factors and developed them as indicators. The survey data was gathered from 158 participants in the preliminary and 480 participants in the main study. The applied analysis techniques were descriptive statistics, the exploratory factor analysis, the confirmatory factor analysis, the correlation analysis, and the path analysis. The results introduced seven user experience factors, 37 detailed user experience factors, and 105 system perception factors as the final user experience indicators. The developed and verified indicators should measure the degree of user experience perceived by users of the knowledge and information resource system and conduct effective evaluations that reflect correlation rather than a simple comparison of each experience factor.

The purpose of this study is to explain the benefits of public libraries in Korea. While many studies had focused on measuring the economic value, this study sought to investigate how do user benefits from public library service and how are these benefits associated with major demographic factors. The questionnaire was developed by two question formats, which is open-ended and 5 Likert scale on 'enjoyment indicators' in earlier studies. Total 313 responses data were collected in S public library in Seoul. As a result, respondents most frequently perceived benefits from library services is reading, saving the money and relaxation. Also, user's benefits level had measured based on the 'enjoyment indicators'. According to the analysis, respondents perceived benefits from library for reading (4.31) and saving the money (4.14). The results show the public libraries' benefits differ in age and careers in 'family relations', 'reading of children', 'cultural life', 'career improvement', and 'saving the money'.

Marketing techniques developed for private organizations are being widely used in libraries. The primary focus in marketing has shifted to maximizing user perceived value from the perspective of library users. This paper examines library as an industry as a way to establish the basis for library's overall value, applies the R-I-R model and its taxonomy of value in using library and information services, and proposes market orientation approach to systematically plan and coordinate academic library marketing activities.

This paper studies a multiple user class variable demand user equilibrium and system optimal condition, and then establishes solution algorithms for them. The traffic network equilibrium is accomplished with basis on following assumptions. For considering heterogeneous road user, several user classes have discrete set of VOTs and the travel demand of each user classes varies according to generalized travel cost. this paper specifically investigates following question on multi-class variable demand: Are user equilibrium flows pattern dependent on the unit (time or money) perceived by road user classes? What is system optimal condition according to the unit used in measuring the travel cost or disutility? Finally, using this network equilibrium condition, The traffic assignment algorithm of each equilibrium condition are established.

The assessment of perceived naturalness aims to elucidate the human perception and explain the interaction between natural environments and humans. The perception of ecological assets that exhibit distinct characteristics within a specific region can manifest in various representations. Based on the users' perceptions and interviews regarding ecological assets, this study assessed the perceived naturalness from a cultural services perspective. Specifically, the discussions on Ansan City's ecological assets and revolved around the inherent value of naturalness in dimensions, such as the necessity for conservation and the sustainable development of ecological assets, the perception of ecosystem benefits, the representativeness as a local asset, and usability. Subsequently, the Q method was employed to present 25 representative ecological assets to 25 users. As a result, user groups with different value systems for each question were identified, and hypothetical personas for cultural service enjoyment were distinguished. The most representative persona among the 25 users was identified as AWP (a type that values the conservation of aquatic ecosystems, prefers waterfront landscapes, and enjoys walking). Since perceived naturalness is conceptually similar to the "benefits perceived by users" in evaluating ecosystem services, it can provide more practical evaluation criteria for cultural services.

This paper explores the framework in which MSNG(Mobile social network game) service providers' strategies to enhance users' intention of continuous usage. Users' perceived values have been considered as the key factors to solicit MSNG user's intention. Moreover, we suggest flow(user's psychological immersion to MSNG) as a mediator variable to inflame users' intention. Results based on 431 respondents shows that MSNG service providers' strategies(i.e., functional, emotional, and social values) directly influence users' intention to use, while those independent variables also show positive relationships towards dependent variables. So we can identify that the efforts to elaborate the users' perceived values are meaningful strategies of MSNG service providers. Also, user's psychological change(i.e. "flow" in this study) is the essential to mediate between MSNG service provider's strategies and building users' intention to use for that MSNG.

This study aims to understand how an influencer's social and physical attractiveness, background and value homophily influences consumer's emotional attachment, which in turn causes user stickiness with regards the influencer's live commerce. We tested all proposed hypotheses among users of the online shopping platform "TaoBao". Ultimately, 297 questionnaires were collected by means of an online survey. The results revealed that social and physical attractiveness positively influence emotional attachment. Meanwhile only value homophily significantly affected emotional attachment, whereas background homophily did not significantly affect emotional attachment. Additionally, emotional attachment was found to significantly influence live commerce stickiness. We also investigated the moderation effect of perceived beauty trends of products sold on live commerce, where the results indicated that high beauty tends to have a higher effect on live commerce stickiness behavior. Lastly, theoretical and managerial implications have been offered.

The primary aim of this paper is to propose a non-linear regression based technique for mapping different network Quality of Service (QoS) factors to an integrated end-user Quality of Experience (QoE) or Mean Opinion Score (MOS) value for an online video streaming service on a mobile phone. We use six network QoS factors for finding out the user QoE. The contribution of this paper is threefold. First, we investigate the impact of the network QoS factors on the perceived video quality. Next, we perform an individual mapping of the significant network QoS parameters obtained in stage 1 to the user QoE based upon a non-linear regression method. The optimal QoS to QoE mapping function is chosen based upon a decision variable. In the final stage, we evaluate the integrated QoE of the system by taking the combined effect of all the QoS factors considered. Extensive subjective tests comprising of over 50 people across a wide variety of video contents encoded with H.265/HEVC and VP9 codec have been conducted in order to gather the actual MOS data for the purpose of QoS to QoE mapping. Our proposed hybrid model has been validated against unseen data and reveals good prediction accuracy.
