This paper presents a dynamic association and natural interaction method for multi-displays composed of smart devices. Users can intuitively associate relations among smart devices by shake gestures, flexibly modify the layout of the display by tilt gestures, and naturally interact with the multi-display by multi-touch interactions. First of all, users shake their smart devices to create and bind a group for a multi-display with a matrix configuration in an ad-hoc and collaborative situation. After the creation of the group, if needed, their display layout can be flexibly changed by tilt gestures that move the tilted device to the nearest vacant cell in the matrix configuration. During the tilt gestures, the system automatically modifies the relation, view, and configuration of the multi-display. Finally, users can interact with the multi-display through multi-touch interactions just as they interact with a single large display. Furthermore, depending on the context or role, synchronous or asynchronous mode is available to them for providing a split view or another UI. We will show the effectiveness and advantages of the proposed approach by demonstrating implementation results and evaluating the method by the usability study.

Purpose: Smoking temptation is the central concept related to relapse within the context of smoking. Therefore :or effective smoking cessation interventions, a scale to measure smoking temptation is necessary. This study was carried out to develop scale to measure smoking temptation. Method: This study utilized Cronbach's alpha, spilt-half coefficient and test-retest correlation in analyzing the reliability of the collected data and expert group, factor analysis, item analysis multitrait-multimethod method and known-group technique to analyze validity. Result: Twenty-five items were selected from a total of 33 items. The Cronbach's alpha coefficient for internal consistency was .93, spilt-half coefficient .91, and 2 week interval test-retest correlation .93 for the 25 items on the smoking temptation scale. Five factors evolved by factor analysis, which explained 57.28 % of the total variance. The smoking temptation scale was effective in differentiating the subjects at each stage of change for smoking cessation and there were significant negative correlations between smoking temptation and self efficacy for smoking cessation and significant positive correlations between smoking temptation and the Fagerstrom Tolerance Questionnaire. Conclusion: The scale for measuring smoking temptation in Korean in this study was evaluated as a tool with a high degree of reliability and validity.

The current advance of IT and the e-commerce triggers the wide practice of dynamic pricing in all industries although the price discrimination has been very cautiously applied in the limited areas in the past. The price discrimination which offers different prices for each customer depending on their preference and buying behaviors has recently gained attention as it could provide superior benefits to sellers. The wide adoption of price discrimination, on the other hand, is reported to face buyer resistances and complaints. Our limited understanding on the perception of price fairness, which we think is key concept in the price discrimination on the Internet-enabled transactions, motives us to investigate factors that affect the perception of price fairness. This study focuses on illusion of control and lateral customer relationship to investigate their effects on price fairness in online auction and group purchase context. By conducting laboratory experiments, our study demonstrates that customers' perception on illusion of control in price determination and advantageous lateral customer relationship significantly affect price fairness perception in both online auction and group purchase environment. The findings are expected to provide researchers and managers with useful insights to develop better pricing strategies and design effective dynamic pricing mechanisms.

Bacterial heat shock protein has been one of the components that are responsible to induce autoimmune disease mechanisms in the pathogenesis of atherosclerosis due to high level of homology in sequence with human counterpart. This mechanism may explain how bacterial infectious disease, such as periodontal disease, might contribute to the acceleration of the disease process of atherosclerosis. Porphyromonas gingivalis which is a major periodontal pathogenic bacterial species, has been implicated as one of the pathogenic bacteria playing the role in this context. The present study has been performed to evaluate the anti-atherosclerotic effect of adoptive transfer of Porphyromonas gingivalis heat shock protein epitope-specific T cell lines into severe combined immunodeficiency (SCID) mice. Peptide no. 15 with amino acid sequence VKEVASKTND-specific T cell line was selected for the transfer. When experimental atherosclerosis was induced in SCID mice adoptively transferred either by the T cell lines (experimental group) or by non-specific mouse T cells (control group), there was no significant difference in the severity and extent of the atherosclerosis induced by hypercholesterol diet.

Objectives : This research investigates the single oral dose toxicity of ACM in SD rats. Methods : ACMs were administered to female and male SD rats, as an oral dose of 5000 mg/kg. Animals were monitored for the mortality and changes in the body weight, clinical signs and gross observation during the 14 days after dosing, upon necropsy. Results : We could not find any mortality. Compared with the control group, significant weight change was not observed in the experimental group. First day after administration, compound-colored stool was observed in all rats. After the second day of administration, the more common symptoms were not observed. There were no gross abnormalities in all cases. [ED NOTE: highlight: given the context, this is very vague] Conclusions : The results obtained in this study suggest that the approximate lethal dose of ACM in both female and male rats were considered as over 5000 mg/kg.

This study investigates the gaps between ideal and actual corporate social responsibility (CSR) by comparing levels of CSR perceptions and examining the relationship differences between CSR perception, perceived quality, and affective trust from a consumer perspective. Data from 315 adult samples were collected through a nationwide online survey. In order to compare ideal and actual CSR, the study employed the approach of latent means analysis (LMA) and multi-group comparisons within the framework of a structural equation modeling (SEM). The result of latent means comparison showed significant differences of perceptions on fashion CSR across ideal and actual contexts. Only actual economic CSR was evaluated higher than in the ideal context and the effect size of inter-management CSR was the largest among seven domains. Multi-group SEM revealed a significant discrepancy between ideal and actual CSR structural models that exhibited relationships of CSR perception, perceived quality, and affective trust. The paths from internal management and ethical CSR to perceived quality and from economic and philanthropy CSR to affective trust were different across ideal and actual contexts. Implying the understanding of consumer CSR perceptions and the mediating role of perceived quality, this study suggests that marketers narrow the gap between ideal and actual CSR.

Despite the continuous efforts of academic libraries to develop various user-centered outreach programs, services and new processes, library anxiety still remains a threat to university students' full use of academic library resources. Meanwhile, a new generation of students, called the "Net Generation," has grown up with developed information and communication technology enter university and must be persuaded to turn to the library. To serve this new group of patrons better, libraries need to adopt new technologies. However, since an initial introduction cost and labor efforts are involved in the integration of the technology, identifying the right time for introduction and the right scope of innovation is essential but difficult. The study proposes a not-yet-well-known, novel experimental design, Regression Point Displacement (RPD), to evaluate an orientation program applying Mobile Augmented Reality (MAR) for STEM students. Since this RPD design requires only one treatment group, the model is expected to be the incomparable and rational way to evaluate the new MAR technology. In the context of an informal learning experience, the findings of the study will determine the effectiveness of an orientation employing the MAR technology.

This study aims to understand microaggressions directed toward international students from the perspective of international exchange professionals, who tend to be in relatively close contact with international students. This study targeted professionals who directly advise and support international students at university international exchange centers in J and G cities. The data were collected by conducting focus group interviews with seven participants in two groups from 25 May to 8 June 2023. Data were collected by conducting focus group interviews of seven participants in two groups from 25 May to 8 June 2023. After analyzing the interview data using thematic analysis, two themes emerged: the experiences of international students and the perspectives of international exchange professionals. The experience of international were further categorized into three sub-themes: differences in cultural context, academic discrimination, and discrimination due to lack of information. The perspectives of international exchange professionals were further categorized into three sub-themes: limited access to infrastructure, different perspectives depending on the level of the country, and consideration as a barrier. It is hoped that the findings of this study, obtained by exploring the microdiscrimination faced by international students at universities, will facilitate the development of different systems and policy recommendations to improve the experiences of international students.

Purpose: The purpose of this study is to analyze the relationship between characteristics of social media sites (SNS) and the intention of Pakistani tourists to visit South Korea while determining the role of usefulness, interestingness, and involvement of tourists. Research design, data and methodology: A research model was developed through the previous research, and the questioner-based survey was conducted on Pakistani tourists visiting Korea. The survey data was collected by following multiple hypotheses: the relationship between SNS tourism information and perception of SNS, the relationship between SNS perception and intention to visit, and adjustment of involvement in the relation between tourism information characteristics, and SNS perception. We used SPSS and AMOS24.0 statistical tools to analyze the hypothesis testing data. Results: Based on the data analysis, the study found that the characteristics of SNS have a positive effect on intention to visit via users' perception like usefulness and interestingness. The involvement has a moderating effect between SNS characteristics and users' perception. In the group with high involvement, the degree of influence of the quality factor of SNS on user perception was greater than in the group with low involvement. Conclusions: This study demonstrated that traveler's involvement has a moderating effect on the relationship between SNS characteristics and visit intention for Pakistani travelers visiting Korea. It shows that practitioners or researchers should establish and operate SNS strategies in consideration of user involvement.
