The e-commerce market is growing faster as demand for non-face-to-face shopping increases due to COVID-19. These changes lead to the expansion of various opportunities for consumers, but companies are required to understand consumer characteristics and reflect them in their sales strategies so that they can be competitive in the market. This study examined how the perceived ease and utility of consumers affect the intention to use the platform according to the technology acceptance model (TAM). As a result, it was confirmed that the price competitiveness, awareness, and ease of use of the platform had a significant effect on the utility. In addition, it was confirmed that there was no moderating effect of user characteristics on the effect of ease of use on the platform intention. These results present important implications for a company's sales strategy, and in future studies, it is necessary to expand the study in consideration of more diverse variables.

Objectives: For diagnosis and evaluation, evaluation tools are needed. Various tools can be used to diagnose and evaluate mental disorders. Among them, psychological tests are widely used. For Korean Standard Classification of Diseases (KCD) diagnosis, psychological tests are also required. Currently developed critical pathway (CP) presented tools for diagnosis and evaluation of mental disorders. The CP suggests the use of tools based on the Clinical Practice Guideline (CPG). Therefore, CPG-based tools should be able to be used in the clinical scene of Korean Medicine for diagnosing and evaluating mental disorders according to CP. Methods: Tools suggested by CPs are summarized. The degree of utilization of tools in CPGs is also summarized. A review was conducted by Korean Medicine neuropsychiatrist experts on tools and user's usage plan. Results: As a result, developed CPs suggested using 19 tools for anxiety disorder, 13 tools for insomnia), 12 tools for Hwabyeong, and 9 tools for dementia. In CPG, 48, 34, 44, and 44 tools were used for anxiety disorder, insomnia, Hwabyeong, and dementia, respectively. Among tools presented in CP, HAM-A, HAM-D, CGI, SAS, and TESS for anxiety disorder, CPG, ISI, and PSQI for insomnia disorder, CPG, STAI, and STAXI for Hwabyeong were frequently used in CPG. For dementia CPG, MoCA, MMSE, HDS, ADL, and ADAS-cog were frequently used. Among them, MoCA, ADL, and ADAS-cog were suggested tools in CP. Conclusions: As a result of analyzing tools suggested and used in the developed CPs and CPGs, it was verified that various tools were used in each study. Most of them were symptom and behavioral evaluation scales. Therefore, symptoms and behavior evaluation scales used more frequently should be able to be used in the clinical scene of Korean Medicine.

A comparative study of a successful mobile payment service and a purported failed one was done as to have some insights to the factors affecting acceptance of the technology. Design/methodology/approach - The strength of three notable theories: theory of diffusion of innovation (DOI), the extended unified theory of user acceptance of information technology (UTAUT2) and self-efficacy theory were use. The self-efficacy of government support inclusion as, a moderating variable in the form of infrastructure, securing transaction and price value revealed the relevance of government in the success of mobile payment service. By means of a field survey of 705 subjects in two separate regions of Africa (East and West), the data was collected and use to test the research model. Findings - The study result shows the importance of the moderating factor of government support to the success of mobile payment of any nation. The result also shows the importance of the perception of relative advantage, compatibility, complexity, social influence as already revealed by other studies. Research implications or Originality - Mobile payment success in some part of Sub-Saharan Africa is well known but also suggested to fail in some Sub-Saharan African countries. Buttressing the need for understanding of the factors affecting mobile payment acceptance. This article empirically examined the factors influencing the success of mobile payment, and we implicated that if the implementation of mobile payment is to be successful for mobile commerce in any nation, adoption, acceptance and use by its citizen is imperative.

Various video conferencing and collaboration applications have emerged due to the global epidemic of new viral infections. In addition to real-time video conferencing, video conferencing applications provide features such as chat and file sharing on various platforms. Because various personal information is stored through functions such as chatting, file and screen sharing, these video conferencing applications are the major target of analysis from a digital forensic investigation. In the case of applications that provide cross-platform, the form of stored data is different depending on the platform. Therefore, to utilize data of video conferencing application for forensic investigation, preliminary research on artifacts stored by platform is required. In this paper, we used the video conferencing applications GoToWebinar and GoToMeeting and analyzed the artifacts generated. As a result, we list the main data from a digital forensic investigation. We identify data stored for each platform provided by GoToWebinar and GoToMeeting and organize artifacts that can estimate user behavior. Also, we classify the data that can be acquired according to the role and environment within the video conference.

This study chose the academic journals related with e-sports for analysis among the top tier journals of National Research Foundation of Korea from 2006 to 2011 to check the academic trend Beginning in 2006, the first study of e-sports was published in the journal related with e-sports. So, the studies from 2006 to 2011 were chosen for analysis. Using Research Information Sharing Service(RISS), the keyword 'e-sports' was searched. By virtue of this process, total 27 studies were selected as final analysis. So, the academic trends are as follows. In Korea, the studies related with e-sports have started from the beginning of 2000s with internet and then it spread out via cable TV. And then from the middle of 2000s, e-sports was discussed seriously. The early subject of the studies usually focused on the measurement of e-sports based on the strategic elements as a product. After that, game addiction and violent tendency which were one of the biggest issues were raised as a constant problem and it became the academic studies of user behavior. E-sports became a recreation culture of teenagers so it has been in charge of the role of exit and the problems related with it have continuously appeared. So, the academic studies tend to have departmentalization like immersion, addiction, sociality, self-regulation and etc. But, there was a tendency that the similar contents were repeated in the view point of subject and method while the subjects were departmentalized. So, for the systematic study of e-sports, development of the unique subject, study method and verification process should be conducted continuously.

The load distribution and deformation of rock-socketed drilled shafts subjected to axial loads are evaluated by a load-transfer method. The emphasis is on quantifying the effect of coupled soil resistance in rock-socketed drilled shafts using the 2D elasto-plastic finite element analysis. Slippage and shear load transfer behavior at the pile-soil interface are investigated by using a user-subroutine interface model (FRlC). It is shown that the coupled soil resistance provides the influence of pile toe settlement as the shaft resistance is increased to an ultimate limit state. The results show that the coupling effect is closely related to the value of pile diameter over rock mass modulus (D/$E_{mass}$) and the ratio of total shaft resistance against total applied load ($R_s$/Q). Through comparisons with field case studies, the 2D numerical analysis reseanably presented load transfer of pile and coupling effect due to the transfer of shaft shear loading, and thus represents a significant improvement in the prediction of load deflections of drilled shafts.

Gaze estimation, which automatically recognizes where a user is currently staring, and object detection based on estimated gaze point, can be a more accurate and efficient way to understand human visual behavior. in this paper, we propose a method to detect the objects within the region of interest around the gaze point. Specifically, after estimating the 3D gaze point, a region of interest based on the estimated gaze point is created to ensure that object detection occurs only within the region of interest. In our experiments, we compared the performance of general object detection, and the proposed object detection based on region of interest, and found that the processing time per frame was 1.4ms and 1.1ms, respectively, indicating that the proposed method was faster in terms of processing speed.
