Over the past decade AIDS research has turned toward the use of pharmacology in HIV prevention, including pre-exposure prophylaxis (PrEP): the use of HIV medication as a means of preventing HIV acquisition in those who do not have it. This paper explores the contradictory reasons offered in support of PrEP—to empower women, to provide another risk-reduction option for gay men—as the context for understanding the social meaning of the experimental trials that appear to show that PrEP works in gay men (...) and heterosexual couples but not single women. The PrEP debates reveal the different ideas about “demedicalization” in the earlier gay health and women’s health movements and highlight the relationship between health activism and critique of research ethics in the context of a global pharmaceutical market.

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)

BackgroundAttention deficit hyperactivity disorder is clinically diagnosed; however, quantitative analysis to statistically analyze the symptom severity of children with ADHD via the measurement of head movement is still in progress. Studies focusing on the cues that may influence the attention of children with ADHD in classroom settings, where children spend a considerable amount of time, are relatively scarce. Virtual reality allows real-life simulation of classroom environments and thus provides an opportunity to test a range of theories in a naturalistic and (...) controlled manner. The objective of this study was to investigate the correlation between participants’ head movements and their reports of inattention and hyperactivity, and to investigate how their head movements are affected by different social cues of different sensory modalities.MethodsThirty-seven children and adolescents with and without ADHD were recruited for this study. All participants were assessed for diagnoses, clinical symptoms, and self-reported symptoms. A virtual reality-continuous performance test was conducted under four conditions: control, no-cue, visual cue, and visual/audio cue. A quantitativecomparison of the participants’ head movements was conducted in three dimensions using a head-mounted display in a VR classroom environment. Task-irrelevant head movements were analyzed separately, considering the dimension of movement needed to perform the VR-CPT.ResultsThe magnitude of head movement, especially task-irrelevant head movement, significantly correlated with the current standard of clinical assessment in the ADHD group. Regarding the four conditions, head movement showed changes according to the complexity of social cues in both the ADHD and healthy control groups.ConclusionChildren and adolescents with ADHD showed decreasing task-irrelevant movements in the presence of social stimuli toward the intended orientation. As a proof-of-concept study, this study preliminarily identifies the potential of VR as a tool to understand and investigate the classroom behavior of children with ADHD in a controlled, systematic manner.

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)

ObjectivesHostile attribution bias is reportedly common from non-clinical population to those with serious mental illness, such as schizophrenia, and is known to be closely related to theory of mind. This study aimed to investigate whether ToM skills mediate the relationship among neurocognitive ability, personality traits, and attribution bias.MethodsA total of 198 non-clinical youths were recruited. To assess their neurocognitive ability and ToM skills, the participants were asked to complete Raven’s Standard Progressive Matrices and the Korean version of the Reading the (...) Mind in Eyes Test. To determine their personality traits, the Eysenck Personality Questionnaire and interpersonal reactivity index were used. To evaluate hostile attribution bias, the Ambiguous Intentions Hostility Questionnaire was administered. Path analysis and bias-corrected percentile bootstrap methods were used to estimate model fit and the parameters of the mediating effects.ResultsBased on model comparison, the best model characterized two direct pathways from psychoticism and the K-RMET to hostility attribution bias and three indirect pathways, wherein SPM, perspective taking, and psychoticism influenced hostile attribution bias through K-RMET. The final model fit indices were good [x2/df = 1.126; comparative fit index = 0.996; root mean square error of approximation = 0.026; standard root mean square residual = 0.026 and Akaike information criterion = 28.251] and the K-RMET fully mediated the association between SPM, perspective taking, psychoticism, and hostile attribution bias.ConclusionThe main findings suggested that ToM skills, such as the RMET, play an important role in explaining the relationship among neurocognitive ability, personality traits, and hostile attribution bias. ToM skills and a remediation strategy may need to be developed to balance the enhanced hostility bias that underlies the paranoia. (shrink)

Video news releases (VNRs) have been criticized when they are used within a newscast without source disclosure because they violate ethical codes related to transparency and consumers' “right to be informed” by whom they are being persuaded. In an experiment, we show how increased persuasion knowledge about VNRs is positively related to beliefs in news commercialization, beliefs in VNR inappropriateness without disclosure, and support for disclosure of VNR material. We suggest that increased knowledge about VNRs without source disclosure measures might (...) harm messages that are not employing the tactic (“false positives”) and lead to a general distrust of all media.

Kant points out the pleasure of the universal communicability of the judgment of taste in the 7th passage of § 9 in the Critique of Judgment. He promises to discuss the subject in a transcendental context further after discussing the Deduction of Pure Aesthetic Judgments. However, he seems to limit his discussion only in an empirical context, neglecting his own commitment. I differentiate the kind of pleasure (which Kant mentioned in the 7th passage) from the intrinsic pleasure of the pure (...) judgment of taste. The latter refers the pleasure in 'the harmonious play of the cognitive powers' stimulated by 'the merely formal purposiveness of a representation of an object'. It seems to have been overlooked that the pleasure of the universal communicability is independent from the intrinsic pleasure of the pure judgment of taste. My goal is to define the another feeling of pleasure by focusing on the analysis of the § 42 where Kant discussesthe possibility of one's interest combined with a pure judgment of taste. I come to the conclusion that another feeling of pleasure is a sort of practical pleasure. It is an interested pleasure in fulfilling the notion of generalizability of one’s state of mind, which is relevant to a moral judgment. Therefore, such pleasure is not actually common to everyone, as Kant insists in § 42, but restricted to those who have already developed the moral interest. (shrink)

Using an innovative fabrication technique, eco-friendly faux leather has been newly developed as a green leather alternative for the Chinese and Korean markets. Value–belief–attitude logic drawn from the heuristic-systemic model :621–642, 1998) and value–belief–norm theory :723–743, 1995) is proposed to explicate the consumer acceptance attitudes toward the EFFL product. The findings from the multi-group structural equation modeling analysis of online data support the relevancy of VBA logic in which utilitarian and hedonic value motivate pro-environmental belief, and the EFFL product attributes (...) significantly mediate belief and positive attitude toward the EFFL product. The discrepancies across two countries and two age cohorts are noteworthy when pro-environmental belief and product-related information lead to different consumer VBA processes in specific market segments. This study presents insights which provide novel opportunities for managerial implementations and theoretical advancements in eco-friendly related subjects and issues. (shrink)

To cope with economic globalization and improve the competitiveness of transnational start-ups, the impact of the work environment and innovation behavior on corporate performance of multinational new ventures is analyzed. First, a model of the interaction among environment, innovation behavior, and enterprise performance is proposed. Then, 296 transnational start-ups in coastal areas are surveyed, and the model results are analyzed. Finally, a series of results are obtained. The results show that from the perspective of psychology, work dynamic organizational learning environment (...) has a positive impact on enterprise performance, and resource environment has a significant positive impact on enterprise performance. Strategic environment also positively affects enterprise performance. Therefore, the working environment of multinational new ventures has a positive impact on firm performance, and the mediating function between the working environment and firm performance is firm innovation behavior. With the research to achieve enterprise innovation of multinational new ventures by improving their response to the dynamic environment, the corporate performance has been greatly promoted, and finally, the new ventures would participate in the international market competition.

An energy efficiency scenario (Joint Institute for a Sustainable Energy and Environmental Future) demonstrates that an energy future built on the use of cost-effective, high-efficiency technologies is clearly within the grasp of South Korea and would justify a nuclear power moratorium with significantly lower carbon dioxide emissions. This is a promising result, especially because applications of other sustainable energy options, such as renewables, decentralized technologies, material recycling/reuse, ecologically based land use planning, forest conservation, sustainable agriculture, and redirection of economic development (...) toward an environment-friendly industrial base, are not included in the analysis. Here lies one of the most fundamental policy choices of the newcentury: Will we build a sustainable energy and environmental future, or will we send forward the burdens and risks of a policy regime that is unwilling to value the future beyond the satisfaction of short-term interests and convenience? It is a critical time for South Korean policy making. (shrink)

Background: While nursing ethics education is commonly provided for undergraduate nursing students in most nursing colleges, consensus on the content and teaching modules for these ethics courses have still not been established. Objectives: This study aimed to examine the effects of nursing ethics education on the moral sensitivity and critical thinking disposition of nursing students in Korea. Research design: A one-group pre- and post-test design was used. Moral sensitivity was measured using the Korean version of the Moral Sensitivity Questionnaire. Critical (...) thinking disposition was measured using the Critical Thinking Disposition Questionnaire. Participants and research context: Participants were 70 undergraduate nursing students who were attending a university located in Seoul, Korea. The nursing ethics education was provided 7 times, from September to December 2010, and comprised 90-min sessions each week. Ethical considerations: This study was conducted in accordance with the Human Subject Research Ethics Committee guidelines. Findings: After the education, the levels for the patient-oriented care, a sub-domain of moral sensitivity, and inquisitiveness, a sub-domain of critical thinking disposition, significantly improved. There were no changes in overall scores for moral sensitivity and critical thinking disposition. There were significant positive correlations between moral sensitivity and critical thinking disposition both pre- and post-intervention. Conclusion: These results reflect the need for ongoing efforts to develop innovative content, structure, and instructional methods for undergraduate nursing ethics education programs. (shrink)

Background With the increasing ethical challenges and dilemmas faced by nurses due to various disasters such as COVID-19 worldwide, there is a need for a new public health ethics education curriculum to strengthen competencies for ethical responses in the nursing field. Objectives This study was aimed to identify the impact of a teaching method utilizing news articles and panel discussion material in the public health ethics education program on nursing students’ thinking regarding ethical issues. Design This was an exploratory study (...) to identify the thinking styles inherent in ethical reflection by analyzing the reflection contents written by nursing students using text mining techniques. Participants 73 among the students taking a nursing ethics course at a university in Seoul, South Korea, voluntarily participated in this study after providing informed consent. Methods The public health ethics program was conducted with sessions held once a week for a total of 7 weeks, and reflections written by nursing students were collected as text files during session 5 to 7. In this study, data preprocessing process, keyword analysis, and LDA topic modeling were sequentially conducted utilizing the R program according to the data analysis procedure of text mining techniques. Ethical considerations This study was conducted under ethics approval from the institution where participants were recruited. Findings and discussion The results of this study show that the teaching method utilizing news articles enhanced rational ethical deliberation from the cognitive aspect, whereas the teaching method utilizing panel discussion material strengthened the response to emotions on a more internal level. Conclusions The teaching method utilizing news articles and panel discussion materials in public health ethics education is expected to be mutually complementary and effective, so further studies are recommended.

Korean biobanks are now adapting to integrate the new paradigm of precision medicine into their fundamental role of promoting health technology. Since the enactment of Bioethics and Safety Act in 2004, the Republic of Korea has developed a regulatory framework that reflects ethical principles. However, the existing regulation of biobanks has recently proven to be limited in responding to newer ethical and legal issues that have arisen. First, as there is an emerging trend for human biospecimens to be stored, managed (...) and distributed as digitalized data, the current role of the Distributive Review Committee may become less important compared to the Data Access Committee. Second, even if public health data is anonymized, the risk of identifiability is growing. This makes a third point relevant, informed consent is crucial to respect the autonomy of patients and research subjects, but current consent rules need to change to reflect the interactive and dynamic communication process, in which information and communication technology plays an increasingly prominent role. Fourth, even though data sharing for research is expected to be altruistic and the sale of human biospecimens and genome data remains prohibited, data sharing practices have become more complicated and are closer to commercial use and commercialization. Given these challenges, there is a pressing need for continuing and deeper deliberation in order to develop a more comprehensive and responsive governance framework. (shrink)

A common view is that relativism requires tolerance. We argue that there is no deductive relation between relativism and tolerance, but also that relativism is not incompatible with tolerance. Next we note that there is no standard inductive relation between relativism and tolerance—no inductive enumeration, argument to the best explanation, or causal argument links the two. Two inductive arguments of a different sort that link them are then exposed and criticized at length. The first considers relativism from the objective point (...) of view ‘of the universe’, the second from the subjective point of view of the relativist herself. Both arguments fail. There is similarly no deductive relation between absolutism and tolerance—neither entails the other—and no inductive connection of any sort links the two. We conclude that tolerance, whether unlimited or restricted, is independent of both relativism and absolutism. A metaethical theory that says only that there is one true or valid ethical code, or that there is a plurality of equally true or valid ethical codes, tells us nothing about whether we should be tolerant, much less how tolerant we should be.

Adolescents often create social relationships with their gaming peers who take on the role of offline friends and peer groups. Through collaboration and competition in the games, the social relationships of adolescents are becoming broader and thicker. Although this is a common phenomenon in online games, few studies have focused on the formation and roles of social capital among adolescent gamers. In particular, longitudinal research that examines the role of social capital in terms of influencing gaming time on adolescent gamers’ (...) psychosocial factors has been minimal. This study was designed to fill this gap to see the long-term effect of social capital among adolescent gamers. Specifically, by using the three-year longitudinal data involving 403 adolescents, we analyzed the effect of gaming time on psychological factors with the moderating role of social capital. Results showed that social capital played a crucial moderating role. In the higher social capital group, gaming time enhanced the degree of self-esteem and life satisfaction. However, a vicious circle was found in the lower social capital group: Gaming time increased the degree of depression but decreased self-esteem, which in turn led to increase in gaming time. These results indicate that games work as an important tool for social capital cultivation among adolescent gamers, which imply successful cultivation of social capital is a key to positive gaming effects. Theoretical and practical implications are discussed. (shrink)

The central question in Aristotle' Metaphysics Zeta- Eta is "What is substance?" and Aristotle answers that substance is essence or substantial form. But it is not clear what in Zeta-Eta Aristotle is inquiring and what the conclusion implies. ;In this study I argue that in Zeta-Eta Aristotle advances a new theory of substance: he establishes a new criterion for substance and identifies substantial form as primary substance. ;The criteria for substance which I take Aristotle to offer are these two. A (...) thing is a substance if and only if its formula of essence is a definition. A thing is a substance if and only if it has no cause other than itself. The former criterion is derived from a consideration of essence and substance from the formulaic point of view, while the latter is derived from a consideration of essence and substance from the metaphysical point of view. ;However, Aristotle recognizes a problem in the logical or formulaic criterion. The difficulty is that the definition of substantial form doesn't seem to be different from the definition of a concrete particular in the composite structure of the formula. The definitions of substantial form and a concrete particular are all composed of parts. I claim that such dissatisfaction with the logical criterion is the main reason why Aristotle declares a new beginning in Zeta 17. ;In Zeta 17 Aristotle claims that it is impossible to identify the cause of the being of substantial form in the same way as the cause of the being of a concrete particular, since the thing asked about is ontologically simple. The cause of the being of a simple thing is itself. Aristotle claims that substantial form, which is the cause of the being of a concrete particular, does not have any cause other than itself. Substantial form is, therefore, primary substance on the metaphysical criterion. ;This interpretation implies that a concrete particular is not to be ranked as primary substance and that this revision can be taken as "a return to, or a renewal of sympathy with, Plato" as G. E. L. Owen described. (shrink)

This paper examines the phenomenon of music in relation to time and time-consciousness based on the philosophies of Augustine, Brentano and Husserl. They analyzed music, or more precisely, the melody of tones and rhythm in their theories of time and time-consciousness, because the process of perceiving music uncloaks the phenomenon of time-understanding.
