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.

This study assessed the demographic characteristics of Koreans engaged in leisure sports activities during the COVID-19 pandemic and the differences in their preventive health behaviors and constraints on leisure activities. For this study, the demographic characteristics of 544 leisure sport participants, who were recruited on a nationwide basis, were examined through an online survey. Then, comparisons between groups were performed using independent t-tests, one-way analysis of variance, and multivariate analysis of variance. Women who participated in both indoor and outdoor leisure (...) sports showed higher adoption of health prevention behaviors than their male counterparts, and married individuals who participated in indoor leisure sports showed higher adoption of health prevention behaviors than unmarried participants. Moreover, individuals who participated in both indoor and outdoor leisure sports by themselves had many interpersonal constraints overall, and the group of married individuals who participated in indoor leisure sports showed structural constraints. In conclusion, leisure sports participants have adopted many health prevention behaviors during the COVID-19 pandemic, but this had led to some interpersonal constraints. These results indicate that, in the case of future pandemics, personal and institutional efforts will need to be made to promote participation in leisure sports and prevent excessive social isolation.

SignificanceElectrical burns can cause severe damage to the nervous system, resulting in autonomic dysfunction with reduced cerebral perfusion. However, few studies have investigated these consequences.AimTo elucidate changes in prefrontal cerebral hemodynamics using functional near-infrared spectroscopy (fNIRS) during the head-up tilt table test (HUT) for patients with electrical burns.ApproachWe recruited 17 patients with acute electrical burns within 1 week after their accidents and 10 healthy volunteers. The NIRS parameters acquired using an fNIRS device attached to the forehead were analyzed in five (...) distinct HUT phases.ResultsBased on their HUT response patterns, patients with electrical burns were classified into the group with abnormal HUT results (APG, n = 4) or normal HUT results (NPG, n = 13) and compared with the healthy control (HC, n = 10) participants. We found trends in hemodynamic changes during the HUT that distinguished HC, NPG, and APG. Reduced cerebral perfusion and decreased blood oxygenation during the HUT were found in both the NPG and APG groups. Patients with electrical burns had autonomic dysfunction compared to the HC participants.ConclusionsUsing fNIRS, we observed that acute-stage electrical burn injuries could affect cerebral perfusion.

The sustainability labeling on the front of a package featured in a print advertisement may influence consumers’ product evaluations and purchase decisions. The findings of this exploratory study suggest that consumers seem to evaluate the sustainability claim more favorably if the advertisement highlights the personal impact on them. Moreover, environmental involvement appears to further moderate the effects of sustainability claims and environmental impact framing. The interactions that emerged in this study suggest that sustainability labeling effects constitute a complex phenomenon that (...) warrants future research. (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)

In the current era of the Sustainable Development Goals, many countries are attempting to strengthen their health system and achieving Universal Health Coverage. The Korean National Health Insurance system functions as a core element of health financing, contributing to achieving UHC by promoting public health and social security through insurance benefits for prevention, diagnosis, treatment, rehabilitation, childbirth, and health promotion. The Republic of Korea achieved 100% NHI coverage of the target population in 1989, 12 years after the introduction of the (...) social insurance system. However, poor coverage of health services and lack of financial protection are major obstacles to achieving UHC. Therefore, the Korean government announced and implemented ‘Moon Jae-in Care’ in August 2017 to enhance the coverage rate of NHI by 70%. First, this study reviews the existing health insurance system in Korea from the perspective of health financing and UHC. Second, it analyses ‘Moon Jae-in Care’, based on the main framework of UHC. Third, it considers the ethical implications of these developments, with focus on the principles of equity, fairness, autonomy, and solidarity. Although the NHI reform is expected to propel Korean health care closer to UHC, many ethical, social, and political issues remain. (shrink)

Chung-ying’s project of onto-hermeneutics draws in order to shed light on the relations between ontology and epistemology in the hermeneutic act. In the process, not only will we be thinking with Cheng and some Western hermeneutic theorists, but we will also be thinking through history by examining the Confucian act of reading. To the extent that any hermeneutic exercise, in accordance with Cheng’s construal, cannot merely be a disembodied act of theoretical knowing but is also moral effort that entails personal (...) cultivation—or, in Heidegger’s and Gadamer’s terms, Bildung—its espousal and its practice necessarily embody a larger conception of culture. In fact, precisely in terms of the intimate engagement with culture, Confucian insights, filtered through Cheng’s onto-hermeneutic lenses, may have much to offer contemporary hermeneutics. (shrink)

Digital contact tracing, in combination with widespread testing, has been a focal point for many plans to “reopen” economies while containing the spread of Covid‐19. Most digital contact tracing projects in the United States and Europe have prioritized privacy protections in the form of local storage of data on smartphones and the deidentification of information. However, in the prioritization of privacy in this narrow form, there is not sufficient attention given to weighing ethical trade‐offs within the context of a public (...) health pandemic or to the need to evaluate safety and effectiveness of software‐based technology applied to public health.

ABSTRACTBy showing its organic linkage between theories of human nature and governance, this article illustrates that the Huainanzi is a scripture that holds a systematic and unique theory. The ideal governance of the Huainanzi is mystical transformation, i.e. the Daoist concept of non-action. Rule by simple Confucian rituals is not at odds with mystical transformation. However, mystical transformation does not include the rule by rituals. Moreover, excessively complicated rituals are incompatible with mystical transformation. Human nature in the Huainanzi does not (...) contradict humanity and righteousness. Human nature’s growth into humanity and righteousness is as natural as the approach of a butterfly to flowers. However, the humanity and righteousness of the Huainanzi are not innate to human nature. Likewise, unlike a flower, a butterfly is not part of a plant. Moreover, artificial flowers, which correspond to excessively complicated rituals, are incompatible wi... (shrink)

Background Moral sensitivity and academic integrity discernment hold paramount importance for healthcare professionals. Owing to distinct undergraduate educational backgrounds, nurses and physicians may exhibit divergent moral perspectives, academic integrity cognisance, and moral sensitivity within clinical environments. A limited number of studies have investigated the disparities and congruencies pertaining to moral sensitivity and academic ethical awareness among nursing and medical students. Objective The study compares moral sensitivity and academic ethical awareness of undergraduate nursing and medical students with and without clinical exposure. (...) Research design A self-administered cross-sectional survey conducted from January to February 2022 was used to collect data from a medical school in Hong Kong. Participants and research context A total of 545 respondents, including 137 nursing students and 408 medical students, completed the questionnaire. Ethical consideration Ethics approval of the study was obtained. Written consent was waived to maintain anonymity because completing the questionnaire was considered implied consent. Findings Both groups of undergraduates demonstrated a high level of bioethics knowledge. In terms of academic integrity, medical students were found to have a less concerned attitude towards punctuality, attendance, and skipping classes. Regarding moral sensitivity, senior medical students with clinical experience put less emphasis on decision-making involving patient participation, while senior nursing students were more hesitant in withholding treatment for incompetent patients who refused treatment. Both nursing and medical students showed decreased moral sensitivity in the ‘conflicts’ domain with increased clinical exposure. Conclusion Study findings contribute to the discussion comparing the ethical attitudes of nursing and medical students. More effort should be made in nursing and medical education to promote practices in line with high academic integrity and to develop the ability to be morally sensitive in professional settings.

This study investigated how coda voicing contrast in English would be phonetically encoded in the temporal vs. spectral dimension of the preceding vowel (in vowel duration vs. F1/F2) by Korean L2 speakers of English, and how their L2 phonetic encoding pattern would be compared to that of native English speakers. Crucially, these questions were explored by taking into account the phonetics-prosody interface, testing effects of prominence by comparing target segments in three focus conditions (phonological focus, lexical focus, and no focus). (...) Results showed that Korean speakers utilized the temporal dimension (vowel duration) to encode coda voicing contrast, but failed to use the spectral dimension (F1/F2), reflecting their native language experience—i.e., with a more sparsely populated vowel space in Korean, they are less sensitive to small changes in the spectral dimension, and hence fine-grained spectral cues in English are not readily accessible. Results also showed that along the temporal dimension, both the L1 and L2 speakers hyperarticulated coda voicing contrast under prominence (when phonologically or lexically focused), but hypoarticulated it in the non-prominent condition. This indicates that low-level phonetic realization and high-order information structure interact in a communicatively efficient way, regardless of the speakers’ native language background. The Korean speakers, however, used the temporal phonetic space differently from the way the native speakers did, especially showing less reduction in the no focus condition. This was also attributable to their native language experience—i.e., the Korean speakers’ use of temporal dimension is constrained in a way that is not detrimental to the preservation of coda voicing contrast, given that they failed to add additional cues along the spectral dimension. The results imply that the L2 phonetic system can be more fully illuminated through an investigation of the phonetics-prosody interface in connection with the L2 speakers’ native language experience.

In this paper, we propose a conceptual framework for constructing a diffusion index of changes in overall perceptions with respect to corruption. The corruption diffusion index we construct lies between 0 (the greatest overall deterioration in corruption perceptions) and 100 (the greatest overall improvement in corruption perceptions) with 50 (no change in corruption perceptions) as the critical reference. The proposed methodology is applied to the 2010/2011 global corruption barometer survey data. Possible refinements of the proposed methodology to capture the potentially (...) multi-dimensional nature of corruption and the practical challenges associated with the empirical implementation are discussed.

A tic disorder (TD) is a neurodevelopmental disorder characterized by tics, which are repetitive movements and/or vocalizations that occur due to aberrant sensory gating. Its pathophysiology involves dysfunction in multiple parts of the cortico-striato-thalamo-cortical circuits. Spontaneous brain activity during the resting state can be used to evaluate the baseline brain state, and it is associated with various aspects of behavior and cognitive processes. Theta–gamma coupling (TGC) is an emerging technique for examining how neural networks process information through interactions. However, the (...) resting-state TGC of patients with TD and its correlation with cognitive function have not yet been studied. We investigated the resting-state TGC of 13 patients with TD and compared it with that of 13 age-matched healthy children. The participants underwent resting-state electroencephalography with their eyes closed. At the global level, patients with TD showed a significantly lower resting-state TGC than healthy children. Resting-state TGC with the eyes closed was significantly negatively correlated with the attention quotient calculated for omission errors in a selective visual attention test. These findings indicate that the resting-state brain network, which is important for the attentional processing of visual information, is dysfunctional in patients with TD. Additionally, these findings support the view that TGC reflects information processing and signal interactions at the global level. Patients with TD may have difficulty gating irrelevant sensory information in the resting state while their eyes are closed. (shrink)

The essay imagines a dialogic interlocution that features the points of convergence and divergence between Hans-Georg Gadamer’s philosophical hermeneutics and Chung-ying Cheng’s onto-hermeneutics, taking note of the fact the latter is an ongoing response to and revision of the former, to the extent it seeks to construct a theory of reading that takes into account both the phenomenological and ontological dimensions of interpretation and understanding.

Superior motor task success has been correlated with participants’ self-reports of a larger-than-actual size of a sport-related target. In the present study, we examined whether a putting practice condition with greater success would differentially impact participants’ self-reported perceptions of the size of the putting hole during acquisition and retention. We randomly assigned participants to one of three different practice conditions and had them self-report their perceived size of the putting hole upon completion of each required putting distance. Although there were (...) no statistically significant differences between motor task success in the acquisition or retention period for the practice conditions, self-reported perceptions of target size were impacted by practice condition. During the acquisition period, participants in the self-controlled success and success-late conditions self-reported that the putting hole was larger than did participants in the success-early condition. In the retention period, participants in the self-controlled success condition perceived the target as larger than those in the success-early condition. These findings are the first to show that practice condition, independent of task success, differentially impacted self-reported perception of a target size. (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.
