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.

Despite the prevailing discourses on the importance of top management ethical leadership, related theoretical and empirical developments are lacking. Drawing on institutional theory, we propose that top management ethical leadership contributes to organizational outcomes by promoting firm-level ethical and procedural justice climates. This theoretical framework was empirically tested using multi-source data obtained from 4,468 employees of 147 Korean companies from various industries. The firm-level analysis shows that top management ethical leadership significantly predicts ethical climate, which then results in procedural justice (...) climate that fully mediates the effects of top management ethical leadership on two organizational outcomes, namely, firm-level organizational citizenship behavior and firm financial performance. The present study provides a plausible theoretical account and empirical validation of a mechanism through which top management ethical leadership enhances organizational performance. (shrink)

Forecasting blood glucose values for patients can help prevent hypoglycemia and hyperglycemia events in advance. To this end, this study proposes an intelligent ensemble deep learning system to predict BG values in 15, 30, and 60 min prediction horizons based on historical BG values collected via continuous glucose monitoring devices as an endogenous factor and carbohydrate intake and insulin administration information as exogenous factors. Although there are numerous deep learning algorithms available, this study applied five algorithms, namely, recurrent neural network, (...) which is optimized for sequence data, and RNN-based algorithms, stacked LSTM, bidirectional LSTM, and gated recurrent unit). Then, a genetic algorithm was applied to the five prediction models to optimize their weights through ensemble techniques and to yield the final predicted BG values. The performance of the proposed model was compared to that of the autoregressive integrated moving average model as a baseline. The results show that the proposed model significantly outperforms the baseline in terms of the root mean square error and continuous glucose error grid analysis. For the valid 29 diabetic patients for the multivariate models, the RMSE was 11.08, 19.25, and 31.30 mg/DL for 15, 30, and 60 min PH, respectively. When the same data were applied to univariate models, the RMSE was 11.28, 19.99, and 33.13 mg/DL for 15, 30, and 60 min PH, respectively. Both the univariate and multivariate models showed a statistically significant difference compared with the baseline at a 5% statistical significance level. Instead of using a model with a single algorithm, applying a GA based on each output of a model with multiple algorithms was found to play a significant role in improving model performance. (shrink)

BackgroundMotor imagery training has a similar effect to that of physical training on motor performance. The objective of this study was to investigate the short-term effectiveness of motor imagery training on response inhibition using the stop signal task.MethodsParticipants were divided into a physical training group, a motor imagery training group, and a motor imagery combined with physical training group. All participants performed 10 SST training sessions over 5 days. Both stop signal reaction time and non-signal reaction time were measured before (...) and after SST training.ResultsThere were significant interaction and time effects, although the group effect was not statistically significant. Bonferroni post hoc analysis showed that MIPT group revealed a significantly greater change in SSRT than PT and MIT groups, while there was no significant difference between PT and MIT groups. SSRT significantly decreased after training in all groups. In NSRT, there was a significant effect of time, but there was no significant interaction effect or group effect.ConclusionResponse inhibition could be enhanced via training, and it was most effective when motor imagery and physical training were combined. We demonstrate that motor imagery training significantly improves response inhibition and should be accompanied by physical training when performing SST. (shrink)

The main purpose of this study was to validate a scale to examine the moral sensitivity of Korean nurses. A pre-existing scale, the Moral Sensitivity Questionnaire (MSQ), developed by Lützén, was used after deletion of three items. The reliability and validity of the scale were examined by using Cronbach’s alpha and factor analysis, respectively. According to the results, reliability of the scale was adequate but its construct validity was not fully supported. Through discussion on evidence of validity, five subconstructs emerged. (...) In particular, unlike the factor structure of the MSQ, two subconstructs, patient-oriented care and professional responsibility, were newly extracted. It was assumed that the other three MSQ subconstructs, conflict, meaning and benevolence (expressed as nurses being ethically good), would not be sensitive to cultural background. Given these findings, interpretations about the meaning of moral sensitivity of Korean nurses are discussed. (shrink)

Four Daoist texts illustrate the dynamic image of the Daoist immortal world on which a Daoist environmental ethics can be built. The first text is the Daodejing with two of the oldest commentaries. The second is Tao Hongjing’s Diagram of Rank and Functions of True Spirits. The third is the collection of poems by Immortal Changchun, titled Panxiji. The fourth is the Morning and Evening Liturgical Prayer Book of the Quanzhen Order, which represents Daoist ecological concerns for the natural world. (...) Daoism not only accords with the impetus and spirit of environmental ethics but can also make a concrete contribution to its implementation. (shrink)

Storytelling is getting increasing attention as one of the effective strategies for revitalizing the local festivals and even regional economies. Yet, the mechanisms through how storytelling helps the success of local festivals are still relatively less known. Using the data from 322 individuals who participated in local festivals using storytelling, our results showed that local festival storytelling is positively related to tourists’ revisit intention. Furthermore, the positive relationship between local festival storytelling and tourists’ revisit intention was serially mediated by authenticity (...) and positive emotion. Theoretical and practical implications are discussed. (shrink)

River water pollution by wastewater can cause significant negative impact on the aquatic sustainability. Hence, accurate modeling of this complicated system and its cost-effective treatment and reuse decision is very important because this optimization process is related to economic expenditure, societal health, and environmental deterioration. In order to optimize this complex system, we may consider three treatment or reuse options such as microscreening filtration, nitrification, and fertilization-oriented irrigation on top of two existing options such as settling and biological oxidation. The (...) objective of this environmental optimization is to minimize the economic expenditure of life cycle costs while satisfying the public health standard in terms of groundwater quality and the environmental standard in terms of river water quality. Particularly, this study improves existing optimization model by pinpointing the critical deficit location of dissolved oxygen sag curve by using analytic differentiation. Also, the proposed formulation considers more practical constraints such as maximal size of irrigation area and minimal amount of filtration treatment process. The results obtained by using an evolutionary algorithm, named a parameter-setting-free harmony search algorithm, show that the proposed model successfully finds optimal solutions while conveniently locating the critical deficit point.

The present study develops an artificial agent that plays the iterative chicken game based on a computational model that describes human behavior in competitive social interactions in terms of fairness. The computational model we adopted in this study, named as the self-concept fairness model, decides the agent’s action according to the evaluation of fairness of both opponent and self. We implemented the artificial agent in a computer program with a set of parameters adjustable by researchers. These parameters allow researchers to (...) determine the extent to which the agent behaves aggressively or cooperatively. To demonstrate the use of the proposed method for the investigation of human behavior, we performed an experiment in which human participants played the iterative chicken game against the artificial agent. Participants were divided into two groups, each being informed to play with either a person or the computer. The behavioral analysis results showed that the proposed method can induce changes in the behavioral pattern of human players by changing the agent’s behavioral pattern. Also, we found that participants tended to be more sensitive to fairness when they played with a human opponent than with a computer opponent. These results support that the artificial agent developed in this study will be useful to investigate human behavior in competitive social interactions. (shrink)

This paper examines the antecedents of organizational commitment for adopting corporate environmental responsibility and green practices in the case of the logistics industry in South Korea. Seven hundred and eighty employees and top management from logistics companies were sampled. The data were analyzed using factor analysis, structural equation modeling techniques, and one-way analysis of variance. The results showed that social expectations, organizational support, and stakeholder pressure were the important antecedents for the adoption of corporate environmental responsibility and green practices. In (...) the path analysis, social expectations had the greatest impact on both stakeholder pressure and green practice adoption. Moreover, we found that the higher the job titles were, the more willing they were to adopt green practices. This indicated that the current top management of Korean logistics companies is well aware of being mandated to make a commitment to corporate environmental responsibility and green practices.

DNA damage repair within telomeres are suppressed to maintain the integrity of linear chromosomes, but the accidental activation of repairs can lead to genome instability. This review develops the concept that mechanisms to repair DNA damage in telomeres contribute to genetic variability and karyotype evolution, rather than catastrophe. Spontaneous breaks in telomeres can be repaired by telomerase, but in some cases DNA repair pathways are activated, and can cause chromosomal rearrangements or fusions. The resultant changes can also affect subtelomeric regions (...) that are adjacent to telomeres. Subtelomeres are actively involved in such chromosomal changes, and are therefore the most variable regions in the genome. The case of Caenorhabditis elegans in the context of changes of subtelomeric structures revealed by long‐read sequencing is also discussed. Theoretical and methodological issues covered in this review will help to explore the mechanism of chromosome evolution by reconstruction of chromosomal ends in nature. (shrink)

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.

With the growing amount of clinical research, regulations and research ethics are becoming more stringent. This trend introduces a need for quality assurance measures for ensuring adherence to research ethics and human research protection beyond Institutional Review Board approval. Audits, one of the most effective tools for assessing quality assurance, are measures used to evaluate Good Clinical Practice and protocol compliance in clinical research. However, they are laborious, time consuming, and require expertise. Therefore, we developed a simple auditing process and (...) evaluated its feasibility and effectiveness. The screening audit was developed using a routine audit checklist based on the Severance Hospital’s Human Research Protection Program policies and procedures. The measure includes 20 questions, and results are summarized in five categories of audit findings. We analyzed 462 studies that were reviewed by the Severance Hospital Human Research Protection Center between 2013 and 2017. We retrospectively analyzed research characteristics, reply rate, audit findings, associated factors and post-screening audit compliance, etc. Investigator reply rates gradually increased, except for the first year. The studies were graded as “critical,” “major,” “minor,” and “not a finding”, based on findings and number of deficiencies. The auditors’ decisions showed fair agreement with weighted kappa values of 0.316, 0.339, and 0.373. Low-risk level studies, single center studies, and non-phase clinical research showed more prevalent frequencies of being “major” or “critical”. Inappropriateness of documents, failure to obtain informed consent, inappropriateness of informed consent process, and failure to protect participants’ personal information were associated with higher audit grade. We were able to observe critical GCP violations in the routine internal audit results of post-screening audit compliance checks in “non-responding” and “critical” studies upon applying the screening audit. Our screening audit is a simple and effective way to assess overall GCP compliance by institutions and to ensure medical ethics. The tool also provides useful selection criteria for conducting routine audits. (shrink)

Pathological gaming among adolescents has been reported to hamper the achievement of a balanced life and to threaten the development of social competencies. Despite the increasing social concerns on the adolescent users, however, the mechanism of gaming behavior of adolescents has not been sufficiently examined. This study explored the mechanism of pathological gaming among adolescents from 3-year longitudinal data of 778 Korean adolescent gamers, by analyzing the effects of negative affects on the degree of pathological gaming through the mediation variables (...) based on the stimulus-organism-response framework. Latent class analysis was used to uncover potential risk groups, and through partial least squares-structural equation modeling analysis, the mediation pathways to pathological gaming were compared between the risk group and the non-risk group. The results highlighted the key role of academic stress on the degree of pathological gaming. In the entire group, academic stress primarily increased pathological gaming through self-control. The mediation path of self-control was the most influential result in the risk group. Aggression was the key mediator between loneliness and pathological gaming in the non-risk group. The theoretical and practical implications of the results were discussed. (shrink)

This descriptive study was undertaken to identify the degree of ethical sensitivity of staff nurses and to analyze the differences in ethical sensitivity in terms of both general and ethics-related characteristics. Participants were 236 staff nurses working in general hospitals in Korea. Ethical sensitivity was measured by means of an instrument developed by the researchers. The results showed that the mean score for the degree of ethical sensitivity was 0.71 out of a possible maximum score of 1 (range 0.30 to (...) 0.97). For general characteristics, there was a significant difference in ethical sensitivity according to age (F (df 2233)-3.99, P-0.02). For characteristics related to ethics, there was a significant difference in ethical sensitivity according to attitude towards the nursing profession (F (df 4231)-2.94, P-0.03). It is therefore recommended that a training program reflecting these variables be developed to enhance staff nurses’ ethical sensitivity. (shrink)

This study proposes two identification cuing factors to understand how corporate social responsibility relates to employees’ identification with their firm. The results reveal that a firm’s CSR initiatives increase employee–company identification. E–C identification, in turn, influences employees’ commitment to their company. However, CSR associations do not directly influence employees’ identification with a firm, but rather influence their identification through perceived external prestige. Compared to CSR associations, CSR participation has a direct influence on E–C identification. On the basis of these findings, (...) it is argued that CSR performance can be an effective way for companies to maintain a positive relationship with their employees. (shrink)

If, today, ‘politics is in culture and culture is relentlessly political’ (Brown, 2002), if the domains of ‘the political’ and ‘the cultural’ can no longer be easily distinguished or kept separate, then contemporary political theory requires an understanding and analysis of cultural politics. This essay undertakes the first stages of such a project by trying to theorize ‘cultural politics’. I argue that ‘cultural politics’ proves to be an object of discourse — it indeed has a certain discursive existence — but (...) not an object of discipline, since no single field or discipline produces it as an object of knowledge. I read this disciplinary failure optimistically, arguing that the study of cultural politics requires a reorientation of theory. The sort of interdisciplinary and multiple-genre work needed to study cultural politics produces a conception of theory as fugitive. Fugitive theory must travel among disciplines, calling on a variety of theoretical and political resources to sustain itself; it refuses the very notion of ‘applied’ theory, insisting that theory ‘is already at work’ in politics (Butler, 1997). To link politics to culture is to practise fugitive theory. And the practice of fugitive theory therefore has the capacity to reveal and explore the workings of cultural politics. (shrink)

On the basis of these findings, it is argued that CSR performance can be an effective way for companies to maintain a positive relationship with their employees. (shrink)

This book is an in-depth interpretation of Max Weber as a political theorist of civil society. On the one hand, it reads Weber's ideas from the perspective of modern political thought, rather than the modern social sciences; on the other, it offers a liberal assessment of this complex political thinker without attempting to apologize for his shortcomings. Through an alternative reading of Weber's religious, epistemological and political writings, the book shows Weber's concern with public citizenship in a modern mass democracy (...) and civil society as its cultivating ground. Kim argues Weber's political thought, thus recast, was deeply informed by Kant, Hegel, Nietzsche and other German political thinkers and also reveals an affinity to the liberal-republican tradition best represented by Mill and Tocqueville. Kim has effectively resuscitated Weber as a political thinker for our time in which civic virtues and civil society have once again become one of the dominant issues. (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)

This longitudinal study examined how nursing students' moral judgment changes after they become qualified nurses working in a hospital environment. The sample used was a group of 80 nursing students attending a university in Suwon, Korea, between 2001 and 2003. By using a Korean version of the Judgment About Nursing Decisions questionnaire, an instrument used in nursing care research, moral judgment scores based on Ketefian's six nursing dilemmas were determined. The results were as follows: (1) the qualified nurses had significantly (...) higher idealistic moral judgment scores than the nursing students; (2) the qualified nurses showed significantly higher realistic moral judgment scores than the nursing students; and (3) when comparing idealistic and realistic moral judgment scores, both the qualified nurses and the nursing students had higher scores for idealistic moral judgment. Further study is recommended to examine changes in moral judgment. (shrink)

As humanoid social robots are developed rapidly in recent years and experimented in social situations, comparing them to humans provides insights into practical as well as philosophical concerns. This study uses the theoretical framework of communication constraints, derived in human–human communication research, to compare whether people apply social-oriented constraints and task-oriented constraints differently to human targets versus humanoid social robot targets. A total of 230 students from the University of Hawaii at Manoa participated in the study. The participants completed a (...) questionnaire, which determined their concern for the five communication constraints (feelings, non-imposition, disapproval, clarity, and effectiveness) in situations involving humans or robots. The results show people were more concerned with avoiding hurting the human’s feelings, avoiding inconveniencing the human interactive partner, and avoiding being disliked by the human and less concerned with avoiding hurting the robot’s feelings, avoiding inconveniencing the robot partner, and avoiding being disliked by the robot. But people did not differ in their concerns of the two task-oriented constraints (clarity and effectiveness) in response to humans versus humanoid robots. The results of the research suggest that people are more likely to emphasize the social-oriented constraints in communication with humans. (shrink)

This longitudinal study examined the development of moral judgement in 37 nursing students attending a university in Suwon, Korea. The participants completed the Korean version of the Defining Issues Test to allow analysis of their level of moral judgement. The development of moral judgement was quantified using ‘the moral development score’ at each stage (i.e. the six stages detailed by Kohlberg) and the ‘P(%) score’ (a measure of the overall moral judgement level). The results were as follows: (1) the moral (...) development score for stage 5A was consistently the highest across the four years of the students’ course, showing significant differences in some sociodemographic factors including home, birth order and monthly income; and (2) the P(%) score was higher in fourth-year (47.47 ± 11.21) than in first-year (46.13±9.73) students. There was no significant difference in the P(%) score according to sociodemographic factors. Further studies will examine in detail the correlation between curriculum and moral judgement development. We suggest that courses in ethics education should be made more relevant. (shrink)

Background: There is increasing evidence to support the efficacy of transcranial direct current stimulation applications in cognitive augmentation and rehabilitation. Neuromodulation achieved with tDCS may further regulate regional cerebral perfusion affiliated through the neurovascular unit; however, components of cerebral perfusion decrease across aging. A novel neuroimaging approach, functional near-infrared spectroscopy, can aid in quantifying these regional perfusional changes. To date, the interaction of the effects of tDCS on cognitive performance across the lifespan and obtained fNIRS hemodynamic responses remain unknown.Objective: This (...) review aims to examine the effects of tDCS on cognitive performance and fNIRS hemodynamic responses within the context of cognitive aging.Methods: Six databases were searched for studies. Quality appraisal and data extraction were conducted by two independent reviewers. Meta-analysis was carried out to determine overall and subgroup effect sizes.Results: Eight studies met inclusion criteria. The overall effect size demonstrates that tDCS can alter cognitive performance and fNIRS signals, with aging being a potential intermediary in tDCS efficacy.Conclusion: From the studies included, the effects of tDCS on cognitive performance and fNIRS metrics are most prominent in young healthy adults and appear to become less robust with increasing age. Given the small number of studies included in this review further investigation is recommended. (shrink)

Intelligent machines are no longer distant fantasies of the future or solely used for industrial purposes; they are real “living” things that operate similarly to humans with verbal and nonverbal communication capabilities. Humans see in such technology the horrifying dangers and the bliss enabled by the saving power. Entrenched in the emotions of hope and fear concerning intelligent machines, humans’ attitudes toward intelligent machines are not free of expectations, judgments, strategies, and selfish agendas. As the discovery of the New Worlds (...) has led to the development of an understanding of self as distinct from the other, narratives on intelligent robots have taken on similar forms of colonial discourse: contradictory manifestations of ethnocentrism (anthropocentrism) and exoticism. Similar to colonial encounters, the racialized Mechanical _Other_ operates like any other marginalized group. Colonial discourse often regards the mechanical _Other_ as both inferior yet exotic, which usually produces a mixed sense of blessing and curse, ambivalence composed of both desire and aversion. In these representations of machinic _otherness,_ one should not miss the fundamental injustice of creating the “Machinic Other” and imposing humans’ viewpoints. The field must expand the purview of intelligent machines to consider the larger historical and cultural forces shaping our understanding of who we are as reflected in the mirror of intelligent machines.
