Construction industry has a relatively higher industrial accident rate than other domestic industries. Thus, to reduce the accident rate, researches on the methodology of worker's safety education combined with new technologies like IT technology have increased. In the light of workers' safety information provision, this study develops a VR(Virtual Reality)-based construction site using the BIM(Building Information Modeling) data. The target structures and geographical features are included in the VR-based construction site where the construction machinery model and worker model are also created using a game engine. For highly effective provision of safety information, video clips with suitable captions corresponding to working processes were made with proper screen directing. They should be appropriately connected to correct worker's operations to improve the work commitment level, sense of reality and inducement of interest. From this scenario, the 3D VR-based construction site, which can be experienced through a VR equipment, was created and in the same platform, the safety information was provided by the video clip combined with the suitable captions. Although the real construction site involves various requirements depending on field situation and the expertness and experience of workers are not consistent, the developed safety information provision based on the VR construction site is expected to effectively reduce the incomplete factors leading to construction accidents by improving the worker's perception of workplace safety.

Effective traffic matrix estimation is the basis of efficient traffic engineering, and therefore, quality of service provision support in IP networks. In this study, traffic matrix estimation is investigated in IP networks and an Elman neural network-based traffic matrix inference (ENNTMI) method is proposed. In ENNTMI, the conventional Elman neural network is modified to capture the spatio-temporal correlations and the time-varying property, and certain side information is introduced to help estimate traffic matrix in a network accurately. The regular parameter is further introduced into the optimal equation. Thus, the highly ill-posed nature of traffic matrix estimation is overcome effectively and efficiently.

This study explores the effects of providing information on the price fairness perception and intention of continuous use in an online fashion platform, given a price difference due to AI algorithm pricing. We investigated the moderating roles of price inequality (loss vs. gain) and technology insecurity. The experiments used four stimuli based on price inequality (loss vs. gain) and information provision (provided or not) on price inequality. We developed a mock website and offered a scenario on the product presentation based on an AI algorithm pricing. Participants in their 20s and 30s were randomly allocated to one of the stimuli. To test the hypotheses, a total of 257 responses were analyzed using Process Macro 3.4. According to the results, price fairness perception mediated between information provision and continuous use intention when consumers saw the price inequality as a gain. When the consumers perceived high technology insecurity, information provision affected the intention of continuous use mediated by price fairness perception.

This study was conducted to compare and analyze the management status of internet homepage of catering companies in Korea for improving internet marketing. An evaluation tool with 6 categories consisting of contents, information update, user's convenience, design, provision of related information, and accessibility was developed and used for the analysis of 6 major catering companies. A five-point likert scale (1=very badly organized, 5=very well organized) was used for evaluating above six categories. The overall mean score for six categories was 2.91 out of 5, showing below the average. The categories received less than 3 points were information update (2.16), user's convenience (2.33), and provision of related information (2.83). The scores for design was the highest (3.66), followed by accessibility (3.33), and contents (3.16). These results suggest that the internet homepaee of the catering companies should be improved especially in the provision of enough information and its update in order to promote their internet marketing.

Objective: The provision of pharmaceutical care service in compliance with good pharmacy practice (GPP) standards is important, but there is lack of studies to investigate the barriers that significantly hinder community pharmacies in Korea from adhering to the standards. This study was aimed to identify the major barriers to provision of pharmaceutical care service in compliance with the proposed pharmacy practice standards which have been developed based on the GPP standards recommended jointly by WHO and FIP. Methods: Questionnaires reviewed by the expert committee were posted for 32 days on the website which is most frequently accessed by community pharmacists. The respondents completed them by checking the scores (Max=5, Min=1) for major barriers to provision of pharmaceutical care service focusing on patient information management and drug use review process in prescription fillings. The answered scores were automatically collected using online data processing. Mean differences between scored data were assessed by ANOVA. Results: Total 321 pharmacists participated in the survey. Results indicated that 'difficulty of diagnosis identification' (m=3.92, SD=1.21), 'lack of time' (m=3.48, SD=1.22) and 'lack of updated clinical information' (m=3.17, SD=1.10) were the major barriers to provision of pharmaceutical care service in patient information management. The main barriers to drug utilization review were 'lack of time' (m=3.32, SD=1.21), 'lack of updated clinical information' (m=3.11, SD=1.17), and 'negative feedbacks or refusals from prescribers' (m=3.00, SD=1.38). There were significant differences among the groups by location, employed number of pharmacists and acceptability to the proposed GPP standards. Conclusion: Difficulties in managing patient clinical information and lack of time were found to be the major barriers in providing pharmaceutical care services in community pharmacies in Korea. Further research is recommended to determine ways to reduce these barriers in order to provide quality pharmaceutical care service that is in compliance with the internationally recognized GPP guidelines.

Frequent outbreak of intrusion of private information is occurring recently not only at portal sites but also in electronic information service of public agencies. Due to these intrusions, it is observed that the citizens tend to avoid providing their private information even to the service for public agencies. Therefore, the object of this research can be explained as demonstrating the influence of the intention of provision for private information to foster the selectronic information ervice of the public agencies. In order to achieve this, this research intends to demonstrate how the experience of the intrusion of the private information affects the concern about the privacy and how the information factor from the public electronic information service has influence on the reliability toward the public. The results showed that the experience of intrusion of privacy, awareness of the danger of privacy, and the sense protection of the information from the manager at public agencies have direct influence on the concern of privacy. Meanwhile, it has been verified that the awareness of information protection of a manager, the systemicity of information protection, and the surveillance and punishment of information protection have influence on the reliability of public agencies.

In this study, we formulated rational criteria to efficiently provide traffic information services via a crafted approach. By utilizing this, we presented a detailed traffic information service providing method that can overcome the limitations of existing link unit information provision system. Three methodologies such as user survey, data mining, and KHCM (Korea Highway Capacity Manual) utilization method were applied to formulate a rational expression standard for traffic information service. Each method was designed to establish a quantitative criterion for various traffic conditions and to enable user-oriented traffic information service in consideration of the traffic principal/compatibility. Considering the results of each methodological analysis in a comprehensive manner, the basic expression standards for traffic information service was formulated. Then we presented improvements such as traffic condition step by road, speed range of traffic condition, expression term of traffic condition and so on. In order to complement the problems of the information provision system of the existing link unit based on the derived improvement criterion, we presented the detailed traffic information service provision method by using the traffic speed data of the second order. And we applied this to the two links of Daegu city. The method presented in this research can improve the quality of traffic information service. Not only it can be used for various fields such as optimal route search, traffic safety service and so on.
