Abstract This research investigates players’ continuance intentions to play massively multiplayer online role-playing games (MMORPGs) by constructing a model based on the concepts of avatar coolness (i.e., avatar attractiveness, avatar originality, and avatar subculture appeal), social identity theory, and flow theory. Analyzing survey-based data from 375 Korean MMORPG players, we found that avatar attractiveness, avatar originality, and avatar subculture appeal were positively related to avatar coolness. In addition, avatar originality positively affects avatar subculture appeal. Moreover, avatar coolness positively affects the continuance intention to play MMORPGs via avatar identification and flow state. This study is the first to develop avatar coolness and explore its role in affecting the intention to play MMORPGs. To offer “cool” avatars, the implications are those game designers should continually update avatars for freshness based on current trends, provide a variety of skins for personalization for user preferences, and offer avatars that are visually appealing to the gaming population. These require continual assessments of the MMORPG player population. [ABSTRACT FROM AUTHOR]

As the concept of the Metaverse rapidly spread, massively multiplayer online role-playing game (MMORPG), one of the Metaverse games, received public's attention again. Additionally, MMORPGs have garnered significant academic interest in multidisciplinary fields, including human-computer interaction, computer science, and psychology. This study provides a general overview of the knowledge structures on MMORPGs in various academic fields using a bibliometric approach. To this end, we collected articles on MMORPGs published between 2001 and 2021 from the Web of Science. Then, main research forces in the field of MMORPGs are identified by examining productive authors, institutions, and countries/regions. Additionally, we applied VOSviewer to conduct co-citation analyses for identifying highly cited authors, journals, and literatures on MMORPGs. The results revealed that the USA and South Korea are the most productive countries. In addition, players' motivation, players' demographics, in-game social interaction, and pathological usage are the main research topics in the field. We expect that our results will help researchers and stakeholders to gain a general understanding of the development of the MMORPG academic field. [ABSTRACT FROM AUTHOR]

Background: The most important sequela of endobronchial tuberculosis (EBTB) is bronchial stenosis, which causes wheezing, dyspnea and obstructive pneumonia. But there have been no reports about applying cryotherapy for granular EBTB that did not show luminal narrowing of the bronchus at diagnosis. Whether this technique is useful for preventing granular EBTB from progressing into stenosis needs to be clarified. Objective: To investigate the efficacy and safety of bronchoscopic cryotherapy for granular endobronchial tuberculosis. Methods: In this study, we analyzed the records of 76 patients with granular EBTB. Diagnosis of TB was confirmed by microbiology or histopathology. Bronchoscopic examinations revealed that the patients had granular endobronchial tuberculosis. Thirty-eight patients received bronchoscopic cryotherapy plus routine anti-tuberculosis chemotherapy and the other 38 patients received routine anti-tuberculosis chemotherapy alone. We compared the treatment effect of these 2 groups. The outcome measures were the changes of lesions, the rate of disappearance of lesions and complications of bronchoscopic cryotherapy. Results: The complete removal rate was 100% in patients with bronchoscopic cryotherapy plus routine anti-tuberculosis chemotherapy; the complete removal rate was 78.9% in patients with anti-tuberculosis chemotherapy alone; the rate of disappearance of lesions in the bronchoscopic cryotherapy plus routine anti-tuberculosis chemotherapy group was faster than that of the anti-tuberculosis chemotherapy alone group. There were no severe complications from bronchoscopic cryotherapy. Conclusions: Bronchoscopic cryotherapy can accelerate the healing of granular EBTB and help to prevent progressive bronchial stenosis due to granular EBTB and is a very safe method.

Purpose: Massive multiplayer online role-playing games (MMORPGs) are representative metaverse games that are thriving in academia and the industry. This study aims to develop an integrated model based on Yee's motivations and the Proteus effect to explore individuals' intentions of playing MMORPGs. Design/methodology/approach: The data were gathered by conducting an online survey (n = 441) for the players of World of Warcraft, an MMORPG. The collected data were analyzed with a structural equation model. Findings: The outcomes of this research reveal that the Proteus effect positively influenced the intentions of the players to play the game via mediations of social, immersion, achievement motivations and enjoyment. Furthermore, the players influenced by the Proteus effect, which enables avatar embodiment and identification, exhibited a stronger intention to play MMORPGs. Originality/value: This research is one of the first attempts to establish a theoretical framework involving the Proteus effect and Yee's motivations. In addition, the findings of this study imply that the Proteus effect should be considered when investigating the individual experience of metaverse games. [ABSTRACT FROM AUTHOR]
