People tend to perceive their loved others (e.g., children, spouse, romantic partner) as their extended selves and then control over the loved others' fashion style corresponding to their self-concept. The study conceptually suggested that people's perceptions on legitimacy to interfere the others and their own fashionability would separately or interactively influence their control over the loved others' fashion style. To investigate the suggestions, an experiment with female participants in their 20's was conducted by using a scenario. The results indicated that participants' perception of legitimacy to interfere their boyfriends or their own fashionability did not have a separate effect on control over their boyfriends' fashion style. However, the legitimacy and the fashionability did have an interactive effect on the control. In particular, for high legitimacy groups, there was no difference in the control between low and high fashionability groups. For low legitimacy groups, the control was stronger in high fashionability group than in low fashionability group.

As one of Virtual Reality devices, HMD(Head-Mounted Device) helps users to experience an extended actual environment by providing them with virtual environment flexibly through the device. HMD considers user experience as importance as well as technical factors. Therefore, this study intended to analyze how the factors such as information quality, enjoyment, self-efficacy can have influence on the adoption of VR device using the extended technology acceptance model. The results showed that information quality and enjoyment have significant influences on perceived ease of use and usefulness. Self-efficacy only affect perceived ease of use. In addition, perceived ease of use and usefulness have influences on intention to use.

This study investigates the change in two theoretical constructs, attitudes toward mathematics and mathematics self-efficacy, among college students involved in a learning community model. The case of this study was a developmental mathematics class offered at a historically black college located in the southeastern United States. Subjects included 31 students enrolled in an introductory mathematics course, some of whom participated in a learning community (treatment group). The participants completed mathematics attitudes and mathematics efficacy instruments twice: at the beginning of the semester and again at the end. Data was analyzed using descriptive statistics and a non-parametric statistic. The results showed that students' attitudes toward mathematics and mathematics self-efficacy are strongly correlated; the mathematical problem-solving efficacy changed significantly over time and it is significantly higher in the treatment group than in the control group; and the treatment group produced better outcomes. These findings indicate that a learning community model can increase students' mathematics self-efficacy beliefs. It is recommended that mathematics self-efficacy and attitudes toward mathematics be measured over an extended period of time when a learning community is implemented.

In this study, a new model to predict the effective elastic constants of composites with spherical fillers is proposed. The original Eshelby model is extended to a finite filler volume fraction without using Mori-Tanaka's mean field approach. When single filler is embedded in the matrix, the effective elastic constants of the composite are computed. The composite is in turn considered as a new matrix, where new single filler is again embedded in the matrix. The predicted results by the present model with a series of embedding procedures are compared with those by Mori-Tanaka, self-consistent, and generalized self-consistent models. It is revealed through parametric studies such as stiffness ratio of the filler to the matrix and filler volume fraction that the present model gives more accurate predictions than Mori-Tanaka model without using the complicated numerical scheme used in self-consistent and generalized self-consistent models.

The advance of information technology has changed the business environment, and the business process between the trading partners has been evolved with these changes. However, the business process between trading partners requires human interface for interchanging information or making a decision even though they collaborate each other or are coupled tightly, and this interrupts seamless business processes between them. To overcome this limitations, a new concept of self-integration has been emerged. The self-integration means a true integration among enterprise applications without human interface, and it might be the future direction of integrations. In this study, we introduced the concept of self-integration environment and business process model for supply chain planning. And, we analyzed the negotiation processes and classified the negotiation patterns for integrated supply chain planning in self-integration environment, and then we proposed a generic business process model for negotiation of extended and integrated supply chain planning by integrating the suggested negotiation pattern with business scenarios.

This study was undertaken to explore the determinants affecting behavioral intention to adopt airport self-service. Based on the theoretical model incorporating the Unified Theory of Acceptance and Use of Technology (UTAUT) and the Technology Acceptance Model (TAM), in this study, a revised and extended model was proposed in order to better explain Airport Self-service adoption. Moreover, the aim was to determine the mediating effect of hedonic motivation on Airport Self-service adoption. The proposed model was empirically tested using survey data provided by 323 respondents and was analyzed using a multiple regression analysis.

The aim of this study is to investigate how travelers' destination visit intentions are influenced by avatar self-congruence in the metaverse platform. We extended the impression management theory by considering both perceived enjoyment and social engagement, and illustrated the interaction effect based on users' digital age. To achieve this, we conducted an online survey with 302 users. The survey results revealed that avatar self-congruence significantly influenced users in terms of perceived enjoyment and social engagement, thereby affecting their destination visit intentions. This study also revealed a significant interaction effect between digital age type and avatar self-congruence on users' perceived enjoyment. The results of this study are expected to provide not only a theoretical reference for metaverse research and travel research but also managerial implications for destination management and metaverse applications.

In this paper, we have fabricated on extended-gate field effect transistor (EGFET)-type protein sensor for the application to a CRP detection. We used the self-assembled monolayer (SAM) to adhere or entrap biomolecules, namely CRP antibodies. The experimental result shows that the proposed SAM is well immobilized on the gold gate surface. So the drain current was varied by antigen-antibody interactions on the gate surface because of the CRP charge. Experimental results related to the formation of SAM, antibody, antigen were obtained by measuring the electrical characteristics of the EGFET device.

This paper analyzed catenary impedance characteristics of relays installed in substation and sectioning post to protect power feeding circuit in the extended power feeding conditions. For this, we modelled AT feeding system using PSCAD/EMTDC and calculated catenary impedance. The relay installed in substation calculated catenary impedance of the extended power feeding area adding catenary impedance of self protection zone. But, the relay installed in sectioning post calculated catenary impedance of the only protection area. Therefore, we confirmed that the more reliable protection way can be utilized using the relay installed in sectioning post.

Utilizing an interconnected set of neuron-like elements, the present study is to provide a method of parameter estimation for a second order linear time invariant system of self-tuning controller. The result from the proposed method is evaluated by comparing with those obtained by the recursive least square (RLS) identification algorithm and extended recursive least square (ERLS) algorithm, and it shows that, although the smoothness of system performance is still to be improved, the effectiveness of shorter computing time is demonstrated which may be of considerable value to real time computing.
