Purpose: The purpose of the research is to explore the role of social media in attracting international patients for cosmetic services in South Korea during the COVID-19 pandemic. The study aims to conceptualize social media as an effective marketing tool for minimizing perceived risks associated with cosmetic services and increasing patient satisfaction. Methods: The study validated proposed hypotheses using the PROCESS macro for SPSS with overseas patients who received cosmetic treatment in private Korean plastic surgery clinics in Busan. Results: This study found that information delivery capability reduced perceived risk and contributed to patient satisfaction, while communication capability did not show any significant relationship with perceived risk and satisfaction. In addition, information delivery capability had a significant direct effect on patient satisfaction, but communication capability did not. Conclusion: It is expected that the outcomes of this study will broaden our understanding of the use of social media in reducing perceived risk and increasing satisfaction.

Purpose – This paper aims to examine the effects of foreign direct investment (FDI) and export on the economic growth of the Commonwealth of Independent States (CIS) and, based on the research results, provide some policy implications for the government of Uzbekistan. Design/Methodology/Approach – A panel data regression model and a panel dataset covering the period 1997 to 2020 were utilized for empirical investigation. The collected data were divided into two groups by income level and two groups by period, namely before and after the global financial crisis of 2008. This paper analyzes the aforementioned groups separately and provides a summary. Pooled OLS, fixed-effects models, and random-effects models were applied through panel data, and the Hausman test and the Breusch-Pagan Lagrange Multiplier test were performed. Findings – The findings corroborate the study’s hypothesis by proving that FDI facilitates growth in the former Soviet republics. Similarly, the comprehensive findings demonstrate that export is crucial for the economic growth of CIS countries, but the fixed-effects regression results for the first country group indicate that the influence of export on economic growth is insignificant when examined separately. Research Implications – The paper recommends that the government of the Republic of Uzbekistan enhance multilateral trade agreements to improve its international trade balance and adopt an export-stimulating strategy. To encourage FDI, the government should take steps to improve the country’s investment climate.

The glut of information aggravated the process of data analysis and other procedures including data mining. Many algorithms were devised in Big Data and Data Mining to solve such an intricate problem. In this paper, we conducted research about the comparison of several similarity measures and community detection algorithms in collaborative filtering for movie recommendation systems. Movielense data set was used to do an empirical experiment. We applied three different similarity measures: Cosine, Euclidean, and Pearson. Moreover, betweenness and eigenvector centrality were used to detect communities from the network. As a result, we elucidated which algorithm is more suitable than its counterpart in terms of recommendation accuracy.
