This study was conducted to examine the effect of institutional mechanisms on customers' trust and continuous purchase intention in open market platforms, The research frame was expanded by setting institutional situations into positive and negative areas in order to examine the relationship between institutional mechanisms and trust in multiple dimensions. The results of this study confirmed that the feedback system, dispute resolution, and intermediary trust factors affect trust in positive areas, and dispute resolution, information security, and intermediary trust affect buyer trust in negative areas. For the relationship between trust and repurchase intention, it was confirmed that if the institutional situation is positive, trust leads to repurchase intention, and in negative areas, trust does not lead to repurchase intention. The results of this study show that institutional mechanisms are a key factor in building trust in online platforms according to institutional circumstances and play a role in offsetting trust in platforms in negative areas.

Background: With the emergent transition of online learning during the COVID-19 pandemic, the need for online/offline blended learning that can effectively be utilized in a team-based learning (TBL) course has emerged. Methods: We used the online metaverse platforms, Gather and Zoom, along with face-to-face teaching methods in a team-based Introductory Pharmacy Practice Experience (IPPE) course and examined students' learning satisfaction and achievement, as well as their preferences to the learning platforms. A survey questionnaire was distributed to the students after the IPPE course completion. All data were analyzed using Excel and SPSS. Results: Students had high levels of course satisfaction (4.61±0.57 out of 5) and achievement of course learning objectives (4.49±0.70 out of 5), and these were positively correlated with self-directed learning ability. While students believed that the face-to-face platform was the most effective method for many of the class activities, they responded that Gather was the most effective platform for team presentations. The majority of students (64.3%) indicated that blended learning was the most preferred method for a TBL course. Conclusion: Students in a blended TBL IPPE course had high satisfaction and achievements with the use of various online/offline platforms, and indicated that blended learning was the most preferred learning method. In the post-COVID-19 era, it is important to utilize the blended learning approach in a TBL setting that effectively applies online/offline platforms according to the learning contents and activities to maximize students' learning satisfaction and achievement.

Many areas are on the verge of disappearing soon due to low birth rates and an increasing number of elderly people. To overcome this crisis, efforts must be made to escape the destruction of the area through the village community. This study was conducted to find out the use of online platforms for village communities and through literature research, current status surveys, and surveys, we wanted to find out how online platforms are being utilized. The study results are summarized as follows. First, urban renewal support projects are currently being conducted under the government-led initiative to revitalize the village community, and online platforms are being used mainly by local governments' urban renewal support centers. Second, if you look at the frequency of online platform usage by ordinary people, you are using Naver the most in all age groups, and next, you are using the website. People in their 20s and 30s use Instagram more than Facebook, while those in their 40s and 50s use Facebook more than Instagram. In utilizing the online platform for the village community, the status and frequency of use of the online platform should be taken into account comprehensively.

Since the advent of the Internet, and the development of smart devices, people have begun to spend more time in online platforms; this phenomenon has created a large number of online Words of Mouth (WOM) daily. Under these changes, one of the important aspects to consider is the conformity effect in online WOM; that is, whether an individual's own opinion would be influenced by the majority opinion of other people. This study, therefore, investigates whether there is the conformity effect in online product ratings for Amazon.com using the method called Markov Chain analysis. Markov Chain analysis considers the stochastic process that satisfies the Markov property, and we assume that the generation of online product ratings follows the process. Under the assumption that people are usually independent when they express their opinion in online platforms, we analyze the interdependency among rating sequences, and we find weak evidence that there exists the conformity effect in online product rating. This suggests that people who leave online product ratings consider others' opinions.

This study aims to analyze the structure and characteristics of the domestic online game industry using network analysis. In particular, two-mode network analysis is employed to measure the network structure, centrality, and cluster for two types of online game platforms, online games and mobile games, from 1996 to 2014. We also conduct a dynamic analysis to capture the structural changes in the ecosystem by internal and external environmental changes before and after turning point for each online game platform. It is revealed that the online game econsystem has the higher number of clusters and higher concentration ratio than those of mobile game ecosystem. In dynamic analysis, both platforms exhibit similar trends over time with the increasing number of clusters, enlargement of largest cluster's size, and decreasing concentration ratio. This study is expected to provide fruitful implications for strategic decision making of online game companies and policy making for the online game industry.

This paper introduces a program structure that minimizes the client's business logic by reducing the client's specifications as a way of minimizing the limitations of online game platforms. The objective of this thesis is to design an online game that is based on a 3-tier client/server structure, and thus using this 3-tier structure to ultimately create an online Sutda game that anyone can enjoy. The progression of newly released games is highly based on the mobile market and the number of online games being launched is decreasing. As the mobile game market grows, more and more multi-platform games are being developed and target platforms within online games are greatly diversifying. Through these situations, this thesis minimizes the client's business logic through a 3-tier structure of application-middleware-database, and also proposes an online game client/server that allows three or more users to participate simultaneously through the server.

This study aims to derive policy implications by analyzing the experiences of Korean ICT startups that participated in the government's online export and trade consultation platform, designed to support ICT startups' overseas expansion during the COVID-19 pandemic. The research methodology involved the analysis of semi-structured, in-depth interviews with six startups who participated in an online export and trade consultation platform, using Giorgi's phenomenological methodology. The analysis resulted in the identification of ten subcategories, including two subcategories for each of the five categories. These categories and subcategories offer a comprehensive understanding of the experiences of ICT startups in navigating the online export and trade counseling platforms. The findings suggest that online export and trade consultation platforms for ICT startups offer efficiency benefits by reducing time and space constraints, but they also reveal limitations in terms of practical business continuity. This study holds academic and practical significance by providing insights into how ICT startups navigate online export and trade counseling platforms during the pandemic.
