The purpose of this study was to identify how older Korean people seek information and their desire to participate in decision making about their health care. A total of 165 elderly people living in Seoul, South Korea, participated in the study. Data were collected during individual interviews using the Autonomy Preference Index. The mean information-seeking score was high. The mean score for their desire to participate with a physician in decision making was lower, but this was higher when family members (...) were involved. The study indicates that many older people want to receive information about their health care. Families (or guardians), as well as older people themselves, should be included in the decision-making process. Nurses can encourage older people to express their wishes, while treating each individual with respect. (shrink)

This study investigated the role of dispositional mindful attention in immediate reactivity to, and subsequent recovery from, laboratory-induced negative emotion. One hundred and fourteen undergraduates viewed blocks of negative pictures followed by neutral pictures. Participants’ emotional responses to negative pictures and subsequent neutral pictures were assessed via self-reported ratings. Participants’ emotional response to negative pictures was used to index level of emotional reactivity to unpleasant stimuli; emotional response to neutral pictures presented immediately after the negative pictures was used to index (...) level of emotional recovery from pre-induced negative emotion. Results indicated that mindful attention was not associated with the emotional response to negative pictures, but it was associated with reduced negative emotion in response to the neutral pictures presented immediately after the negative pictures, suggesting better recovery as opposed to reduced reactivity. This effect was especially pronounced in later experimental blocks when the accumulation of negative stimuli produced greater negative emotion from which participants had to recover. The current study extends previous findings on the relationship between dispositional mindfulness and reduced negative emotion by demonstrating that mindful attention may facilitate better recovery from negative emotion, possibly through more effective disengagement from previous stimuli.

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)

Algorithms increasingly make managerial decisions that people used to make. Perceptions of algorithms, regardless of the algorithms' actual performance, can significantly influence their adoption, yet we do not fully understand how people perceive decisions made by algorithms as compared with decisions made by humans. To explore perceptions of algorithmic management, we conducted an online experiment using four managerial decisions that required either mechanical or human skills. We manipulated the decision-maker, and measured perceived fairness, trust, and emotional response. With the mechanical (...) tasks, algorithmic and human-made decisions were perceived as equally fair and trustworthy and evoked similar emotions; however, human managers' fairness and trustworthiness were attributed to the manager's authority, whereas algorithms' fairness and trustworthiness were attributed to their perceived efficiency and objectivity. Human decisions evoked some positive emotion due to the possibility of social recognition, whereas algorithmic decisions generated a more mixed response – algorithms were seen as helpful tools but also possible tracking mechanisms. With the human tasks, algorithmic decisions were perceived as less fair and trustworthy and evoked more negative emotion than human decisions. Algorithms' perceived lack of intuition and subjective judgment capabilities contributed to the lower fairness and trustworthiness judgments. Positive emotion from human decisions was attributed to social recognition, while negative emotion from algorithmic decisions was attributed to the dehumanizing experience of being evaluated by machines. This work reveals people's lay concepts of algorithmic versus human decisions in a management context and suggests that task characteristics matter in understanding people's experiences with algorithmic technologies.

We develop an approach to the longstanding conjecture of Kierstead concerning the character of strongly nontrivial automorphisms of computable linear orderings. Our main result is that for any η-like computable linear ordering, such that has no interval of order type η, and such that the order type of is determined by a -limitwise monotonic maximal block function, there exists computable such that has no nontrivial automorphism.

Faced with the choice between saving one person and saving two others, what should we do? It seems intuitively plausible that we ought to save the two, and many forms of consequentialists offer a straightforward rationale for the intuition by appealing to interpersonal aggregation. But still many other philosophers attempt to provide a justification for the duty to save the greater number without combining utilities or claims of separate individuals. I argue against one such attempt proposed by Iwao Hirose. Despite (...) being consequentialist, his argument is aggregation-free since it relies on a non-aggregative value judgement method, instead of interpersonal aggregation, to establish that (other things being equal) a state of affairs is better when more people survive therein. I do not take issue with its consequentialist element; rather, I claim that there is no good reason to adopt the method in question, and thus no good reason to be moved by his argument overall. What we are in search of is not merely a logically possible method that can produce the conclusion that we already want, but one that we have good reason to adopt. Hirose's argument elegantly demonstrates how it could possibly be true that it is right to save the greater number; but it fails to show that we have reason to believe so - even when we do not combine the interests of different individuals.

The rapid development of machine-learning algorithms, which underpin contemporary artificial intelligence systems, has created new opportunities for the automation of work processes and management functions. While algorithmic management has been observed primarily within the platform-mediated gig economy, its transformative reach and consequences are also spreading to more standard work settings. Exploring algorithmic management as a sociotechnical concept, which reflects both technological infrastructures and organizational choices, we discuss how algorithmic management may influence existing power and social structures within organizations. We identify (...) three key issues. First, we explore how algorithmic management shapes pre-existing power dynamics between workers and managers. Second, we discuss how algorithmic management demands new roles and competencies while also fostering oppositional attitudes toward algorithms. Third, we explain how algorithmic management impacts knowledge and information exchange within an organization, unpacking the concept of opacity on both a technical and organizational level. We conclude by situating this piece in broader discussions on the future of work, accountability, and identifying future research steps. (shrink)

Background Conventional consent practices face ethical challenges in continuously evolving digital health environments due to their static, one-time nature. Dynamic consent offers a promising solution, providing adaptability and flexibility to address these ethical concerns. However, due to the immaturity of the concept and accompanying technology, dynamic consent has not yet been widely used in practice. This study aims to identify the facilitators of and barriers to adopting dynamic consent in real-world scenarios. Methods This scoping review, conducted in December 2022, adhered (...) to the PRISMA Extension for Scoping Reviews guidelines, focusing on dynamic consent within the health domain. A comprehensive search across Web of Science, PubMed, and Scopus yielded 22 selected articles based on predefined inclusion and exclusion criteria. Results The facilitators for the adoption of dynamic consent in digital health ecosystems were the provision of multiple consent modalities, personalized alternatives, continuous communication, and the dissemination of up-to-date information. Nevertheless, several barriers, such as consent fatigue, the digital divide, complexities in system implementation, and privacy and security concerns, needed to be addressed. This study also investigated current technological advancements and suggested considerations for further research aimed at resolving the remaining challenges surrounding dynamic consent. Conclusions Dynamic consent emerges as an ethically advantageous method for digital health ecosystems, driven by its adaptability and support for continuous, two-way communication between data subjects and consumers. Ethical implementation in real-world settings requires the development of a robust technical framework capable of accommodating the diverse needs of stakeholders, thereby ensuring ethical integrity and data privacy in the evolving digital health landscape.

ObjectivePrevious research has shown that adolescents in single-mother households are at heightened risk for adjustment problems. However, limited studies have investigated the mechanisms leading to adolescent problem behaviors in single-mother households. To address this research gap, this study applied the Family Stress Model to examine how single mothers’ material hardship is linked to adolescent problem behaviors, focusing on the mediating roles of mothers’ depression and mother-adolescent closeness. The moderating role of adolescent school connectedness in the relationships between mother-adolescent closeness and (...) school connectedness and between mothers’ depression and school connectedness was also investigated.Materials and methodsThe study analyzed data from 1,384 adolescents and their single mothers who participated in the Fragile Families and Child Wellbeing Study at Wave 6. The associations between study variables were analyzed using structural equation modeling by decomposing the direct, indirect, and total effects of material hardship on adolescent problem behaviors. School connectedness’s interactions with mother-adolescent closeness and mothers’ depression were also examined.ResultsResults showed a significant indirect relationship between material hardship and adolescent problem behaviors through sequential mediation of mothers’ depression and mother-adolescent closeness. Mothers’ depression also significantly mediated the relationship between material hardship and problem behaviors. Lastly, school connectedness moderated the relationship between mother-adolescent closeness and adolescents’ internalizing behaviors. The association between mother-adolescent closeness and adolescents’ internalizing behavior was weaker for adolescents with higher levels of school connectedness.ConclusionThe results indicate the important indirect effect of economic strain on adolescents’ problems behaviors in single-mother households, which has been less emphasized compared to the effects in earlier childhood. High rates of material hardship and adolescent problem behaviors in single-mother families call for multifaceted interventions focusing on family processes and protective factors, including school environment.

From the perspective of the system of systems development, system-level functional testing is required for designing subsystems. This study utilizes modeling and simulation techniques to analyze the operational behaviors of the subsystems and confirm data communication between them. The targeted system in the study is a naval combat system, which is a typical type of defense cyber-physical system. Three types of models were designed for the simulation testing of the NCS: a combat-management model for simulating the overall computational activities, physical (...) models to confirm the intrasubsystem behaviors, and data integration models to test the intersubsystem communications. These models are realized with the Model-View-ViewModel design pattern, which strongly facilitates graphical user interfaces being decoupled from model logic and data. We consider underwater combat scenarios as an application. Six significant physical subsystems within the NCS are simulated and tested: a ship-steering system, an inertial navigation system, a global navigation satellite system, a periscope, sonar systems, and a plotting board. We expect that the proposed work will play a principal role when analyzing the behaviors and communications of defense CPSs and providing an environment for functional testing as a digital twin.

Smartphone app-use patterns will predict professional golfers’ athletic performance, and the use time of serious apps would be associated with improved performance. This longitudinal 4-week observation of 79 professional golfers assessed golf handicaps and smartphone app-use patterns at the start of the Korean professional golf season and 2 and 4 weeks later. We classified use as social networking, entertainment, serious apps, and others. Use time of entertainment apps increased for non-improved golfers but did not change for improved golfers. Use time (...) of serious apps increased for improved golfers and decreased for non-improved ones. Changes in golf handicaps were positively correlated with changes in entertainment app use time and negatively correlated with changes in serious app use time. Professional golfers’ sports performance was not associated with smartphone use time but was with the smartphone app type. The management of smartphone app-use patterns is important for professional golfers’ performance. (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)

Molodtsov introduced 1999 the concept of soft set as a new mathematical tool for dealing with uncertainties that is free from the difficulties that have troubled the usual theoretical approaches. In this paper we apply the notion of soft sets by Molodtsov to ordered semigroups. The notions of soft ordered semigroup, soft ordered subsemigroup, soft left ideal, and left idealistic soft ordered semigroup are introduced, and various related properties are investigated.

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.

Comparative Political Theory and Cross-Cultural Philosophy explores new forms of philosophizing in the age of globalization by challenging the conventional border between the East and the West, as well as the traditional boundaries among different academic disciplines. This rich investigation demonstrates the importance of cross-cultural thinking in our reading of philosophical texts and explores how cross-cultural thinking transforms our understanding of the traditional philosophical paradigm.

BackgroundThis study aimed to identify the healthcare providers’ experience and perspectives toward end-of-life care decisions focusing on end-of-life discussion and physician’s order of life-sustaining treatment documentation in Korea which are major parts of the Life-Sustaining Treatment Act.MethodsA cross-sectional survey was conducted using a questionnaire developed by the authors. A total of 474 subjects—94 attending physicians, 87 resident physicians, and 293 nurses—participated in the survey, and the data analysis was performed in terms of frequency, percentage, mean and standard deviation using the (...) SPSS 24.0 program.ResultsStudy results showed that respondents were aware of terminal illness and physician’s order of life-sustaining treatment in Korea well enough except for some details. Physicians reported uncertainty in terminal state diagnosis and disease trajectory as the most challenging. Study participants regarded factors (related to relationships and communications) on the healthcare providers’ side as the major impediment to end-of-life discussion. Study respondents suggested that simplification of the process and more staff are required to facilitate end-of-life discussion and documentation.ConclusionBased on the study results, adequate education and training for better end-of-life discussion are required for future practice. Also, a simple and clear procedure for completing a physician’s order of life-sustaining treatment in Korea should be prepared and legal and ethical advice would be required. Since the enactment of the Life-Sustaining Treatment Act, several revisions already have been made including disease categories, thus continuous education to update and support clinicians is also called for.

Evidentials and Modals offers an in-depth account of the meaning of grammatical elements representing evidentiality in connection to modality, focusing on theoretical/formal perspectives by eminent pioneers in the field and on recently discovered phenomena in Korean evidential markers by native scholars in particular. Evidentiality became a hot topic in semantics and pragmatics, trying to see what kind of evidential justification is provided by evidentials to support or be related to the 'at-issue' prejacent propositions. This book aims to provide a deeper (...) understanding of such evidentiality in discourse contexts in a broad range of languages such as American Indian, Korean and Japanese, Turkish and African languages over the world. In addition, an introduction to the concept of evidentiality and theoretical perspectives and recent issues is also provided. Contributors are Alexandra Y.
