Purpose - The purpose of this study is to identify the preceding factors that form pro-social tourism behavior intent in a pendemic situation and to present theoretical and practical implications for the role of individuals for a safe tourism environment. Design/methodology/approach - This study conducted an analysis by collecting 420 valid questionnaires targeting citizens who have lived in Korea continuously for more than one year. For the analysis, a confirmatory factor analysis (CFA) and a structural equation model (SEM) were used, and a multi-group confirmatory factor analysis (MCFA) and a multi-group structural equation model (MSEM) were used to verify the difference by age group. Findings - First, cognitive and affective risk perception for Covid-19 had a significant (+) effect on the ascription of responsibility to tourists, and affective risk perception and ascription of responsibility had a significant (+) effect on personal norms. Second, personal norms have been shown to have a significant (+) influence on prosocial tourism behavior intention, and prosocial tourism behavior intention has a significant (+) influence on WTP on safety tourism. Research implications or Originality - Tourism behavior in a pendemic situation can affect the spread of infection. In this respect, this study attempted to confirm how moral norms affect pro-social tourism behavior from a personal point of view. In addition, we tried to present practical implications by identifying the impact of personal norms on willing to pay for a safe tourism environment.

The objective of this study is to examine the media richness theory and the social information processing model by analyzing the effect of media experience on media perception and communication process. To accomplish this objective, a laboratory experiment was conducted. The independent variable was text medium experience and a face-to-face medium was added as a control group. The dependent variables were medium perception and communication process. Medium perception includes perceived richness, medium feeling, task satisfaction, and communication satisfaction. Communication processes were also analyzed to compare each treatment group. The results can be summarized into two facts. First, face-to-face group showed higher perceived richness than text medium group. And experienced text medium group perceived their text medium richer than inexperienced text medium group. Second, experienced text medium groups showed more interactions between subjects than inexperienced text medium group. Experienced text medium group also showed more agreements and meta-communication which could be found in face-to-face group. The result of this study supported media richness theory by finding that face-to-face medium was perceived richer than text medium, And the results also proved social information processing model by comparing experienced text medium group and inexperienced text medium group. The text medium, although thought to be the leanest one, could be perceived richer if users had lots of experience on it.

This study aims to explore age-related differences with the assessment tools in the web-based 3D virtual model house and to propose the 3D model house criteria which everyone can use easily. The participants came from three age groups, ranging from their 20s to their over 40. Presence, Usability and Space perception and cognition in the experiment for navigating and evaluating the web-based 3D model house were measured and compared through one-way ANOVA and two-way ANOVA. The results and conclusions are as follows. (1) The younger the participants were, the more positive they evaluated the experiment on Presence. However, 20s needed higher presence than other two groups. (2) 30s and over 40 groups evaluated that the 3D virtual model house was more efficient than an actual model house on Usability. When the participants were younger, the values of 'expressivity' factor were higher. (3) The younger the participants were, the more positive they perceived the virtual environment (VE) on Space perception and cognition scale. There were no significant differences in the selection of dwelling size and the floor plan type. There were no significant differences of interaction effects between age and online gaming experience on Presence and Usability. The results of the current study demonstrate that there are differences among age groups and older groups have difficulty navigating and assessing in a VE. Although older groups take longer to adapt in the VE, they regard the 3D model house as an effective tool for purchase of house.

This study purposed to analyze difference in the perception of service quality between physical therapy patients and physical therapists and to provide basic materials for maintaining high service quality that meets patients' expectation in each service area. For this study, we conducted a questionnaire survey with physical therapy patients and physical therapists in Jeju from the 6 to 30 of January, 2010. In the survey, we received 133 questionnaires from patients and 125 from physical therapists, and used them in analysis. The instrument used in this study to measure service quality was prepared by the researcher through adapting and supplementing the SERVQUAL model developed by Parasuraman et al (1991). For our physical therapy environment, and it consisted of a total of 23 questions in five areas, namely, tangibility, reliability, responsiveness, assurance, and empathy. Patients' perception of service quality was high in order of reliability, assurance, empathy, responsiveness, and tangibility. In four areas with exception of reliability, quality perceived by patients was lower than that perceived by physical therapists, and particularly in responsiveness(t=2.82, p=.00) and empathy(t=2.02, p=.04), the difference between patients and physical therapists was statistically significant. In order to reduce the difference in the perception of service quality between patients and physical therapists, it is considered necessary to enhance physical therapists' perception of service quality and to prepare measures for improving service equality so that services would be provided through respectful communication with maintaining the dignity of patients, rather than focusing on disease.

Environment perception and three-dimensional (3D) reconstruction tasks are used to provide unmanned ground vehicle (UGV) with driving awareness interfaces. The speed of obstacle segmentation and surrounding terrain reconstruction crucially influences decision making in UGVs. To increase the processing speed of environment information analysis, we develop a CPU-GPU hybrid system of automatic environment perception and 3D terrain reconstruction based on the integration of multiple sensors. The system consists of three functional modules, namely, multi-sensor data collection and pre-processing, environment perception, and 3D reconstruction. To integrate individual datasets collected from different sensors, the pre-processing function registers the sensed LiDAR (light detection and ranging) point clouds, video sequences, and motion information into a global terrain model after filtering redundant and noise data according to the redundancy removal principle. In the environment perception module, the registered discrete points are clustered into ground surface and individual objects by using a ground segmentation method and a connected component labeling algorithm. The estimated ground surface and non-ground objects indicate the terrain to be traversed and obstacles in the environment, thus creating driving awareness. The 3D reconstruction module calibrates the projection matrix between the mounted LiDAR and cameras to map the local point clouds onto the captured video images. Texture meshes and color particle models are used to reconstruct the ground surface and objects of the 3D terrain model, respectively. To accelerate the proposed system, we apply the GPU parallel computation method to implement the applied computer graphics and image processing algorithms in parallel.
