While social interaction and play in a VR environment are becoming ever more popular, little is known about how social VR games affect users. The purpose of this study was to elucidate the role of several contingent factors in social VR games by modeling the relationships between involvement, well-being, depression, self-esteem, and social connectedness. A conditional process-moderated mediation model of the measured variables was analyzed with 220 pieces of collected data. The result showed that: the direct effect of involvement on (...) well-being was significant, and the index of moderated mediation involving depression, self-esteem, and social connectedness was significant. We conclude that high levels of involvement in social VR games by socially isolated users with low self-esteem can negatively affect their well-being. The findings of this study contribute in several ways to our understanding of the effect of social VR games upon users and provide important practical implications. (shrink)

This study investigates the effects of cultural orientation and the degree of disdain for robots on the preferred conversational styles in human-to-robot interactions. 203 participants self-reported on questionnaires through a computer-based online survey. The two requesting situations were intended to simulate the participants' interactions with humanoid social robots through an Internet video-phone medium of communication. Structural equation modeling was performed to examine the mediating role of mechanistic disdain between multicultural orientation and conversational constraints. The findings reveal that between the two (...) dimensions of multicultural orientation, only open-mindedness inversely influences mechanistic disdain. Mechanistic disdain, in turn, negatively affects three face-related conversational constraints, thereby leading to a lesser concern for robots' feelings, for minimizing impositions on robots, and for avoiding robots' negative evaluations. The implications of our findings on humans' relations with virtual robot entities and on the future development of humanoid robots are discussed. (shrink)

BackgroundAlthough the Life-Sustaining Treatment (LST) Decision Act was enforced in 2018 in Korea, data on whether it is well established in actual clinical settings are limited. Hospital-acquired pneumonia (HAP) is a common nosocomial infection with high mortality. However, there are limited data on the end-of-life (EOL) decision of patients with HAP. Therefore, we aimed to examine clinical characteristics and outcomes according to the EOL decision for patients with HAP.MethodsThis multicenter study enrolled patients with HAP at 16 referral hospitals retrospectively from (...) January to December 2019. EOL decisions included do-not-resuscitate (DNR), withholding of LST, and withdrawal of LST. Descriptive and Kaplan–Meier curve analyses for survival were performed.ResultsOf 1,131 patients with HAP, 283 deceased patients with EOL decisions (105 cases of DNR, 108 cases of withholding of LST, and 70 cases of withdrawal of LST) were analyzed. The median age was 74 (IQR 63–81) years. The prevalence of solid malignant tumors was high (32.4% vs. 46.3% vs. 54.3%, P = 0.011), and the ICU admission rate was lower (42.9% vs. 35.2% vs. 24.3%, P = 0.042) in the withdrawal group. The prevalence of multidrug-resistant pathogens, impaired consciousness, and cough was significantly lower in the withdrawal group. Kaplan–Meier curve analysis revealed that 30-day and 60-day survival rates were higher in the withdrawal group than in the DNR and withholding groups (log-rank P = 0.021 and 0.018). The survival of the withdrawal group was markedly decreased after 40 days; thus, the withdrawal decision was made around this time. Among patients aged below 80 years, the rates of EOL decisions were not different (P = 0.430); however, mong patients aged over 80 years, the rate of withdrawal was significantly lower than that of DNR and withholding (P = 0.001).ConclusionsAfter the LST Decision Act was enforced in Korea, a DNR order was still common in EOL decisions. Baseline characteristics and outcomes were similar between the DNR and withholding groups; however, differences were observed in the withdrawal group. Withdrawal decisions seemed to be made at the late stage of dying. Therefore, advance care planning for patients with HAP is needed. (shrink)

ObjectiveThis pilot study aimed to evaluate the efficacy of a digital cognitive behavioral therapy in patients with cancer experiencing sleep problems.MethodsA total of 57 participants aged 25–65 years were randomly assigned to three groups—21 participants to a dCBT program, 20 participants to an app-based attentional control program, and 16 participants to a waitlist control group—and evaluated offline before and after the program completion. Of the 57 participants, there were a total of 45 study completers, 15 participants in each group. The (...) dependent variables were sleep quality scores, measured by the Pittsburgh Sleep Quality Index and health-related quality of life scores, measured using the Short-Form 36, and attentional bias scores from a dot-probe computer task.ResultsFor both the intention-to-treat and study-completers analyses, a significant increase supported by a large effect size was found in the quality of sleep score of the HARUToday Sleep group compared to both the app-based attentional control and the waitlist control group. However, no significant changes were found in the quality of life and attentional bias scores.ConclusionOur results suggest that the HARUToday Sleep app has the potential to serve as an intervention module to enhance the sleep quality of patients with cancer experiencing sleep problems.

Background: Infectious disease outbreaks such as COVID-19 and MERS pose a major threat to healthcare workers' physical and mental health. Studies exploring the positive changes gained from adapting to traumatic events, known as post-traumatic growth, have attracted much attention. However, it is unclear which factors or experiences lead to PTG among HCWs. The purpose of this mixed-method study was to investigate factors associated with PTG among HCWs who experienced the MERS outbreak in South Korea, and fully describe their experience of (...) developing PTG.Methods: Quantitative data from 78 participants were collected using psychometric tools for Psychological distress, Resilience, and Support for coping, and Post-traumatic growth. Qualitative interviews were conducted with seven nurses. Data were analyzed using the qualitative content analysis method according to the sub-themes of resilience, which was the main factor associated with PTG.Results: We found resilience to have a significant impact on PTG. Thus the qualitative interviews were analyzed using the core concepts of resilience. Qualitative interviews with nurses illustrated how participants experienced the development of resilience in terms of its sub-factors: hardiness, persistence, optimism, and support.Conclusion: HCWs who endured the MERS outbreak showed high levels of PTG, and the analysis of the interview data provided a fuller understanding on the experience of remaining resilient and developing PTG. These results provide practical and pragmatic information helpful for developing intervention strategies and protocols that can help HCWs transform adversity into growth and development. (shrink)

ABSTRACTDespite the wide and daunting array of cross‐cultural obstacles that the formulation of a global policy on advance directives will clearly pose, the need is equally evident. Specifically, the expansion of medical services driven by medical tourism, just to name one important example, makes this issue urgently relevant. While ensuring consistency across national borders, a global policy will have the additional and perhaps even more important effect of increasing the use of advance directives in clinical settings and enhancing their effectiveness (...) within each country, regardless of where that country's state of the law currently stands. One cross‐cultural issue that may represent a major obstacle in formulating, let alone applying, a global policy is whether patient autonomy as the underlying principle for the use of advance directives is a universal norm or a construct of western traditions that must be reconciled with alternative value systems that may place lesser significance on individual choice. A global policy, at a minimum, must emphasize respect for patient autonomy, provision of medical information, limits to the obligations for physicians, and portability. And though the development of a global policy will be no easy task, active engagement in close collaboration with the World Health Organization can make it possible. (shrink)

Tumor‐infiltrating lymphocyte (TIL) therapy is a promising approach for treating refractory or advanced solid cancers by using autologous TILs harvested from cancer tissues. Despite the heterogeneity of cancer, TIL therapy can potentially produce a positive therapeutic response, including complete remission.After decades of research on lymphocyte functions, culture/expansion methods, therapeutic protocols, and multiple clinical trials, TIL therapy has finally reached a stage where it can be formally approved for clinical use.TIL therapy is expected to hold a unique position among anti‐cancer therapeutic (...) options as a standard intervention. To successfully introduce TIL therapy into clinical settings, there is a need to expand therapeutic indications and set up the best protocols for cancer tissue sampling and manufacturing, and related clinical trials. Moreover, studies on next‐generation TIL therapy have already begun, and post‐approval real‐world data will promote and support further research. (shrink)

In the United States, targeted school shootings have become a distinct genre of violence. In this essay, Bryan Warnick, Sang Hyun Kim, and Shannon Robinson examine the social meanings that exist in American society that might contribute to this phenomenon, focusing on the question: “Why are schools conceptualized as appropriate places to enact this form of gun violence?” The authors analyze the social meaning of American schooling by using empirical data, everyday observations, films, and poetry, and then connect these (...) points of meaning to stories of individual school shooters. Through this analysis, three aspects of school stand out. First, schools are places of both real and symbolic violence, where force and power often rule the day. Second, schools are places connected to expectations of hope and refuge, friendship and romance, and when these expectations are not met, bitter resentment flows against schools. Third, suburban schools are seen as places of expressive individualism, which, in rare cases, is manifest in terms of “expressive violence.” Together, these points of meaning can make schools, for some youth, seem like appropriate places to express violent intentions. The essay concludes by speculating about how this analysis can be applied to prevent school shootings. (shrink)

This study focuses on CEO hubris and its detrimental effect on corporate financial performance along with an examination of critical corporate governance contingencies that may moderate the negative effect. From 654 observations of 164 Korean firms over the years 2001–2008, we found that CEO power exacerbated the negative effect of CEO hubris on corporate financial performance, whereas board vigilance mitigated it. This study provides empirical evidence that entrenchment problems arising from CEO hubris would be exacerbated as CEOs become more powerful, (...) but weakened as board of directors become more vigilant. Theoretical contributions and practical implications will be discussed. (shrink)

STS research has devoted relatively little attention to the promotion and reception of science and technology by non-scientific actors and institutions. One consequence is that the relationship of science and technology to political power has tended to remain undertheorized. This article aims to fill that gap by introducing the concept of sociotechnical imaginaries. Through a comparative examination of the development and regulation of nuclear power in the US and South Korea, the article demonstrates the analytic potential of the imaginaries concept. (...) Although nuclear power and nationhood have long been imagined together in both countries, the nature of those imaginations has remained strikingly different. In the US, the state’s central move was to present itself as a responsible regulator of a potentially runaway technology that demands effective containment. In South Korea, the dominant imaginary was of atoms for development which the state not only imported but incorporated into its scientific, technological and political practices. In turn, these disparate imaginaries have underwritten very different responses to a variety of nuclear shocks and challenges, such as Three Mile Island (TMI), Chernobyl, and the spread of the anti-nuclear movement.

This study integrates theories of diffusion and social identity to conceptualize the diffusion of Sustainability Report as a result of a firm’s identification with its reference groups. Specifically, we first hypothesize four different sources of external stakeholder pressures driving the diffusion. Next, we argue that the source of external stakeholder pressures has a differential effect on the adoption of SR for firms that claim their identity on sustainability management. For firms with organizational identity claims, in-group stakeholder pressure will amplify whereas (...) out-group stakeholder pressure will dampen the adoption. We test our theory using an event-history analysis of 675 publicly traded firms in Korea during the period of 2003–2010. The results show that all four sources of external pressure serve as mechanisms through which SR spread in Korea. More importantly, we find support for the moderating role of organizational identity claims in the effect of external pressures. We discuss how organizational identity matters in the diffusion of corporate social initiatives along with implications for policy makers. (shrink)

Dreamscapes of Modernity offers the first book-length treatment of sociotechnical imaginaries, a concept originated by Sheila Jasanoff and developed in close collaboration with Sang-Hyun Kim to describe how visions of scientific and technological progress carry with them implicit ideas about public purposes, collective futures, and the common good. The book presents a mix of case studies—including nuclear power in Austria, Chinese rice biotechnology, Korean stem cell research, the Indonesian Internet, US bioethics, global health, and more—to illustrate how the concept (...) of sociotechnical imaginaries can lead to more sophisticated understandings of the national and transnational politics of science and technology. A theoretical introduction sets the stage for the contributors’ wide-ranging analyses, and a conclusion gathers and synthesizes their collective findings. The book marks a major theoretical advance for a concept that has been rapidly taken up across the social sciences and promises to become central to scholarship in science and technology studies.

The present study examined the attitudes of Filipino middle school students toward physical education and the associations between PE attitude and various personal and external correlates of PE. In total, 659 middle school students, aged between 12 and 19 years, participated in the study. The Physical Education Attitude Scale was used to measure affective, cognitive, and motivational/behavioral attitudes of adolescent students toward PE. Results showed that middle school students had moderate general attitudes toward PE. Female students had more favorable attitudes (...) toward PE when their teacher was male than female. When the teacher was female, male students were more satisfied with the PE curriculum than female students. When the teacher was male, female students were more comfortable with the PE curriculum than male students. Finally, students' PE attitude did not decrease as they got older, regardless of student sex. The findings provide a different perspective for the field and underscore the importance of not only the PE curriculum but also the student–teacher relationship. To prevent the decline in students' positive attitude and encourage positive behaviors toward PE and activities, teachers should be very considerate about their interactions with students of the same sex; school administrators, meanwhile, should focus at providing PE teachers with special training courses to enhance both their teaching and communication capabilities.

A recent paradigm shift in music research has allowed scholars to examine the macro- and micro-processes taking place within musical performance and underlying cognitive processes. Tying in with phenomenological theories of embodied perception and cognition, this paper focuses on bodily musical activity relevant to the acquisition of instrumental musical skills—the process of learning music. Dynamic interaction with musical instruments, accompanied by the interplay of action and passion, involves body image and body schema, whose status oscillates in different phases of the (...) acquisition of instrumental musical skills; this interaction allows humans to direct attention from their bodily states—the proximal—to the quality of musical sounds and a unity of musical experience—the distal. It is thus argued that shaping music by means of playing a musical instrument can be conceived of as an embodied process, of understanding the forms of one’s own experience as related to the musical world that is created by one’s bodily activity.

Face recognition payment, an innovative financial technology service, is a recently developed mode of payment service that has garnered attention in the offline market, particularly in China. However, studies examining the adoption of FRP by consumers are scarce. Therefore, this study proposed a causal model built on the Unified Theory of Acceptance and Use of Technology, and key predictors related to the intention of using FRP were identified. The structural equation model-based results obtained from 305 Chinese participants demonstrated that the (...) intention was most affected by relative advantage. In addition, performance expectancy, effort expectancy, social influence, and perceived risk also had a significant impact. However, trust was found to not significantly affect consumers’ intentions, despite it negatively influencing perceived risk. Thus, the results of this study are expected to provide a set of guidelines for companies regarding the implementation of FRP. (shrink)

BackgroundExperience with open disclosure and its study are restricted to certain western countries. In addition, there are concerns that open disclosure may be less suitable in non-western countries. The present study explored and compared the in-depth perceptions of the general public and physicians regarding open disclosure in Korea.MethodsWe applied the COREQ checklist to this qualitative study. We conducted 20 in-depth interviews and four focus group discussions with 16 physicians and 18 members of the general public. In-depth interviews and focus group (...) discussions were performed according to semi-structured guidelines developed according to a systematic review of open disclosure. We conducted a directed content analysis by analyzing the verbatim transcripts and field notes in accordance with the predetermined guidelines.ResultsOpen disclosure perceptions were summarized in terms of the “five Ws and one H”. All physician and general public participants acknowledged the normative justifiability of open disclosure. The participants mostly agreed on the known effects of open disclosure, but the physicians had negative opinions on its expected effects, such as decreased intention of the general public to file lawsuits and increased credibility of medical professionals. Generally, the participants thought that open disclosure is required for medical errors causing major harm. However, the physicians and general public had conflicting opinions on the need for open disclosure of near misses. Most physicians did not know how to conduct open disclosure and some physicians had bad experiences due to inappropriate or incomplete open disclosure.ConclusionPhysicians and the general public in Korea acknowledge the need for open disclosure. Guidelines according to the type of patient safety incident are required to encourage physicians to more readily conduct open disclosure. Furthermore, hospitals need to consider organizing a dedicated team and hiring experts for open disclosure. (shrink)

We examined the associations between the characteristics of Instagram users and the features of their photographs. Narcissism, life satisfaction, and loneliness were employed for user variables and the features at high- and low-levels were employed to analyze the Instagram photographs. An online survey was conducted with 179 university students, and their Instagram photographs, 25,394 in total, were collected and analyzed. High-level features were extracted using Computer Vision and Emotion Application Programming Interfaces in Microsoft Azure Cognitive Services, and low-level features were (...) extracted utilizing the program written by the authors. The results of correlation analysis indicate that narcissism, life satisfaction, and loneliness were significantly associated with a part of photograph features at high- and low-levels. The results of the predictive analysis suggest that narcissism, loneliness in total, and social loneliness could be predicted with acceptable accuracy from Instagram photograph features, while characteristics such as life satisfaction, family loneliness, and romantic loneliness could not be predicted. Implications of this research and suggestions for further research were presented. (shrink)

An incoherent feed‐forward loop (FFL) is one of the most‐frequently observed motifs in biomolecular regulatory networks. It has been thought that the incoherent FFL is designed simply to induce a transient response shaped by a ‘fast activation and delayed inhibition’. We find that the dynamics of various incoherent FFLs can be further classified into two types: time‐dependent biphasic responses and dose‐dependent biphasic responses. Why do the structurally identical incoherent FFLs play such different dynamical roles? Through computational studies, we show that (...) the dynamics of the two types of incoherent FFLs are mutually exclusive. Following from further computational results and experimental observations, we hypothesize that incoherent FFLs have been optimally designed to achieve distinct biological function arising from different cellular contexts.

In light of the dramatic growth of Chinese learners worldwide and a need for cross-linguistic research on Chinese literacy development, this study drew upon theories of visual complexity effect (Su & Samuels, 2010) and dual-coding processing (Sadoski & Paivio, 2013) and investigated a) the effects of character properties (i.e., visual complexity and radical presence) on character acquisition and b) the relationship between individual learner differences in radical awareness and character acquisition. Participants included adolescent English-speaking beginning learners of Chinese in the (...) U.S. Following Kuo et al. (2014), a novel character acquisition task was used to investigate the process of acquiring the meaning of new characters. Results showed that a) characters with radicals and with less visual complexity were easier to acquire than characters without radicals and with greater visual complexity; and b) individual differences in radical awareness were associated with the acquisition of all types of characters, but the association was more pronounced with the acquisition of characters with radicals. Theoretical and practical implications of the findings were discussed. (shrink)

This study assessed the knowledge and perception of human biological materials (HBM) and biorepositories among three study groups in South Korea. The relationship between the knowledge and the perception among different groups was also examined by using factor and regression analyses. In a self‐reporting survey of 440 respondents, the expert group was found more likely to be knowledgeable and positively perceived than the others. Four factors emerged: Sale and Consent, Flexible Use, Self‐Confidence, and Korean Bioethics and Biosafety Action restriction perception. (...) The results indicate that those who are well aware of the existence of biobanks were more positively inclined to receive the Sale and Consent perception. As a result of the need for high quality HBMs and the use of appropriate sampling procedures for every aspect of the collection and use process, the biorepository community should pay attention to ethical, legal, and policy issues.

Background Nurses providing care to patients with end-of-life or terminal illnesses often encounter ethically challenging situations leading to moral distress. However, existing quantitative studies have examined moral distress using instruments that address general clinical situations rather than those specific to end-of-life care. Furthermore, qualitative studies have often been limited to participants from a single unit or those experiencing moral distress-induced circumstances. A comprehensive and integrated understanding of the overarching process of moral distress is vital to discern the unique circumstances surrounding (...) end-of-life care and its consequential impacts. Research objectives To explore the moral distress experiences of nurses who are frequently involved in caring for patients with end-of-life or terminal illnesses and apply it to two existing theories: the model of moral distress and the ecological model. Research design A qualitative descriptive approach was employed. Participants and research context Seven focus group interviews involving 30 nurses were performed. The subsequent transcriptions underwent rigorous content analysis. Ethical considerations We obtained Institutional Review Board approval from a university. Focus group interviews were conducted with nurses who agreed to participate and signed the consent form. Findings The moral distress-inducing factors and nurses’ perceived impact of moral distress were identified and categorized based on moral distress theories and ecological models. A total of 15 categories and 30 subcategories across the following 4 domains were derived: (1) intrapersonal, (2) interpersonal, (3) organizational, and (4) structural factors. Conclusions End-of-life-specific circumstances induced moral distress among nurses, with both negative and positive impacts identified. Effective organizational and policy support is essential to manage conflicts, form a healthy organizational culture, provide training, and prevent unnecessary expenses due to the negative consequences of moral distress.

This study provides an in-depth examination of the relationship between environmental, social, and governance (ESG) performance and the idiosyncratic volatility of Korean companies. In line with the risk-mitigation view, the study finds that strong ESG performance is associated with a reduction in a firm's idiosyncratic volatility. The impact of ESG performance on reducing firm volatility was particularly evident during the COVID-19 pandemic, highlighting the role of ESG performance in risk mitigation during crisis periods. The study also shows that companies with (...) strong ESG performance in industries that are highly sensitive to ESG factors are particularly adept at reducing idiosyncratic volatility. These findings underscore the importance of ESG enhancement for both firm managers and policymakers, particularly within ESG-sensitive industries. (shrink)

The aim of this study was to investigate factors associated with seriously ill patients’ preferences for their family and physicians making resuscitation decisions on their behalf. Using SUPPORT II data, the study revealed that, among 362 seriously ill patients who were experiencing pain, 277 (77%) answered that they would want their family and physicians to make resuscitation decisions for them instead of their own wishes being followed if they were to lose decision-making capacity. Even after controlling for other variables, patients (...) who preferred the option of undergoing cardiopulmonary resuscitation (CPR) in the future were twice as likely, and those who had had ventilator treatment were four-fifths less likely, to rely on their family and physicians than those who did not want CPR (odds ratio (OR)-2.28; 95% confidence interval (CI) 1.18-4.38) or those who had not received ventilator treatment (OR-0.23; 95% CI 0.06-0.90). Psychological variables (anxiety, quality of life, and depression), symptomatic variables (severity of pain and activities of daily living) and the existence of surrogates were not significantly associated with patients’ preferences for having their family and physicians make resuscitation decisions for them. Age was not a significant factor for predicting the decision-making role after controlling for other variables. (shrink)

Cover Photograph: Resolving developmental genetics in the fourth dimension: an illustration (by Kwang‐Hyun Cho himself) of the principle of dynamic network motifs in Drosophila development. Hitherto largely considered in terms of time‐invariant networks, drosophila development is viewed in the article by Man‐Sun Kim, Jeong‐Rae Kim, and Kwang‐Hyun Cho as the result of networks of gene interactions that change during the course of development. Using this paradigm, pivotal developmental events can be correlated with particular changes from one constellation of (...) gene interactions to a different one, and the method allows the identification of certain network motifs that are not identifiable using static approaches.
