Internet of Things-based environments pose various challenges due to their anytime/anywhere computing, and the efficient cryptographic based key management is one of the major challenges in Internet of Things. The key management life cycle consists of initialization, key generation, key registration, key backup, key update, key recovery, and key revocation. Our contribution in this paper is to summarize the state-of-the-art key management schemes and techniques in different scenarios, such as mobile ad hoc networks, wireless sensor networks, and the Internet of (...) Things environments. Further different issues related specifically to the Internet of Things environment are discussed and the causes and effects pertaining to the security breach for Internet of Things are identified. Furthermore, in this research work, we develop a novel permutation of threshold and identity-based key management schemes for the Internet of Things environment and have proposed future directions to counteract the attacks on confidentiality, integrity, authentication, and availability of security services in the Internet of Things environment and identified the two key management schemes, that is, identity and threshold schemes for Internet of Things, to resolve Internet of Things key management issues and maximum possible security services effective implementation. We evaluate our scheme with the help of mathematical and statistical techniques. (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)

This paper argues that Foucault’s genealogy of racism deserves appreciation due to the highly original concept of racism as biopolitical government. Modern racism, according to Foucault, is not merely an irrational prejudice, a form of socio-political discrimination, or an ideological motive in a political doctrine; rather, it is a form of government that is designed to manage a population. The paper seeks to advance this argument by reconstructing Foucault’s unfinished project of a genealogy of racism. Initially, the paper situates the (...) genealogy of racism within the context of Foucault’s work. It belongs to a period of transition between the mature and the late part of Foucault’s work, more specifically a period of transition from discipline to governmentality. The paper proceeds by reading closely key passages from the 1976 lectures at Collège de France in which Foucault proposes to rethink racism as a form of biopolitical government. While Foucault’s genealogy of racism remains an incomplete project, lacking for example any substantial treatment of European colonialism, the paper proposes to expand the Foucauldian analysis by linking it to the pan-German discourse between 1890 and 1914. Finally, the paper reflects on some of the implications of the Foucauldian analysis, in particular attempts to understand and counter contemporary forms of racism. Foucault’s genealogy of racism, in short, shows us the constructedness of our racialized world and challenges us to develop new and more effective strategies to change it. (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.

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)

Our narratives about intelligent machines reprise the same modes in which humans have historically dealt with "other" groups of humans, especially during the era of colonialism. Addressing unconscious assumptions involving race, gender, hierarchy, power, imperialism, and capitalism in the post-colonial world, this book argues that cultural narratives regarding intelligent machines have much to do with colonial attitudes and mindsets. Human attitudes toward intelligent machines, colored by such ideological and cultural biases, cumulatively manifest themselves as cultural narratives of a racialized Machine (...) Other. This book explores how examining the emotions underlying our narratives about intelligent machines can provide insights into the human psyche and be a catalyst for authentic encounters with intelligent machines. It will beckon you to question long-held assumptions, confront the complexities of AI and racial dynamics, and embark on a quest for deeper understanding of yourself. (shrink)

The demand for organ transplants, both globally and in South Korea, substantially exceeds the supply, a situation that might have been aggravated by the enactment of the Life-Sustaining Treatment Decision Act (LSTDA) in February 2018. This legislation may influence emergency medical procedures and the availability of organs from brain-dead donors. This study aimed to assess LSTDA’s impact, introduced in February 2018, on organ donation status in out-of-hospital cardiac arrest (OHCA) patients in a metropolitan city and identified related factors. We conducted (...) a retrospective analysis of a regional cardiac arrest registry. This study included patients aged 16 or older with cardiac arrest and a cerebral performance category (CPC) score of 5 from January 2015 to December 2022. The exclusion criteria were CPC scores of 1–4, patients under 16 years, and patients declared dead or transferred from emergency departments. Logistic regression analysis was used to analyse factors affecting organ donation. Of the 751 patients included in this study, 47 were organ donors, with a median age of 47 years. Before the LSTDA, there were 30 organ donations, which declined to 17 after its implementation. In the organ donation group, the causes of cardiac arrest included medical (34%), hanging (46.8%), and trauma (19.2%). The adjusted odds ratio for organ donation before the LSTDA implementation was 6.12 (95% CI 3.09–12.12), with non-medical aetiology as associated factors. The enactment of the LSTDA in 2018 in South Korea may be linked to reduced organ donations among patients with OHCA, underscoring the need to re-evaluate the medical and legal aspects of organ donation, especially considering end-of-life care decisions.

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 paper attempts to provide a concise but systematic presentation of the discursive ontology of the social that underpins the thought of the Argentinian political theorist Ernesto Laclau. First articulated by Laclau and his collaborator Chantal Mouffe at the historical conjuncture of the late twentieth century that witnessed the disintegration of established leftist political visions and the rise of a plurality of new social movements, the post-structuralist discursive ontology on which Laclau bases his theorization of hegemony as the paradigm of (...) politics is one that continues to exert a powerful influence on contemporary post-foundational political thought, discourse analysis, and “left populist” political movements. This paper traces the fundamental claims of that ontology, paying special attention to Laclau’s theses apropos the limits of universality and impossibility of “fullness.” In the final third of this paper, the French philosopher Alain Badiou’s approach to the conceptualization of social change is employed as a foil to draw some key implications of Laclau’s elevation of “hegemony” as the universal form of the political for political thought and practice.
