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.

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.

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)

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)

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)

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)

Kim Dong-ri et Seo Jeong-ju sont deux monuments de la littérature coréenne du XX e siècle. Les deux écrivains nouèrent une profonde amitié à partir des années 1930 et contribuèrent ensemble à la reconstruction du milieu littéraire de la Corée après la période de l’Occupation japonaise. Dans quel contexte le romancier et le poète se sont-ils rencontrés? Quelles sont les caractéristiques de leur lien amical? Comment celui a-t-il résisté aux vicissitudes du temps et au désaccord momentané lié aux circonstances? À (...) partir d’éléments biographiques, autobiographiques et de leurs témoignages réciproques, nous découvrons que la connaissance intime de l’univers de l’un par l’autre et leur inspiration mutuelle se fondent sur les valeurs littéraires et humanistes qu’ils partagent : fins connaisseurs de la littérature du monde, ils valorisent dans leur écriture des éléments proprement coréens.

This paper examines the theoretical background and actual behavior in a gaming tournament with endogenous timing where a person has more incentive, structure, and time to form a strategy. The baseline treatment suggests that subgame perfection is a reasonable predictor of behavior –- subjects made 170 of 208 theoretically predicted choices of best actions, with the majority of mistakes made in timing choices by the players who did not survive the cut to the second round. Four sensitivity treatments established that (...) the design feature that lead to more predictable behavior was time to think –- 745 of 960 correctly predicted decisions with more time versus 595 of 960 with less time. A random effects Probit model suggests that the key design feature that closed the gap between predicted and observed behavior was not necessarily the non-linear payoffs created by the tournament design, but rather that the key was providing people with more time to think about their strategy.

This paper focuses on the Korean suffix -te, which has been variously analyzed as a marker of tense, aspect, tense–aspect, mood, mood–tense, or evidentiality. I argue against all of these approaches and propose instead that -te is a spatial deictic past tense, which triggers an evidential environment. It refers to a certain past time when the speaker either observed an event or some evidence of the event within his (her) perceptual field. Thus, the denotation of -te is ‘overlap’, not between (...) the speaker's perceptual field and the event itself, but between the speaker's perceptual field and the evidence of the event at the past reference time. To account for this denotation, propose an ‘evidence trace’ function as well as a ‘speaker's perceptual trace’ function (cf. M. Faller, J Semantics 21:45–85, 2004). My analysis shows that suffixes like -ess (which is traditionally analyzed as a perfect) play two roles, as an indirect evidential and a perfect, depending on whether they appear with the spatial deictic tense -te or with a simple deictic tense. I argue that in Korean two distinct tense systems—the regular tense–aspect system and the spatial deictic tense–evidential system—exist in parallel. Thus the proposed analysis allows evidentials to be subsumed under the formal theory of tense, aspect, and mood. (shrink)

This article aims to contribute to the understanding of Roy Bhaskar's philosophical evolution from critical realism to the philosophy of meta-Reality. Following Bhaskar's own terminology, I define his intellectual journey as the ‘identification of dualism and duality within non-duality’ by proposing that anti-anthropism plays a key role in the developmental consistency of his system from critical realism via dialectical critical realism to meta-Reality. For this purpose, I compare Bhaskar's philosophy with Andrew Collier's theory of human rationality and spiritual emancipation based (...) on Christianity and Tu Wei-Ming's anthropocosmic understanding of human beings and nature based on Confucianism.

This article brings to light discourses that constituted the education of Asian-American children in California in the second half of the nineteenth century. Guided by Foucaultian ideas and critical race theory, I analyze California public school laws, speeches of a governor-elect and a superintendent, and a report of the board of supervisors, from the 1860s to the 1880s. During this targeted period, the images and narratives of Asian-American children were inscribed with racism. Racializing politics rendered them to be disqualified from (...) attending public schools. Segregated schooling for them was legally ordered and therefore unquestioned. It was a discursive practice implemented on their bodies by dint of a mechanism of a spatial division. This article reveals the shifting dominancy of discourses regarding Asian-American children. Rather than accepting the given historical facts, I intend to reread historical texts in order to rethink the education of Asian-American children through a Foucaultian encounter with critical race theory. Acknowledging different interpretations of the past events is a way of rethinking them and interrogating the history through the revelation of different histories in the education for Asian-American children.

Generally speaking, the ethics of Korean society today are going through an unstable stage, in which the traditional ethics of the East are becoming blended with the Western values that were introduced during the modern age. The resulting chaos has become a critical issue for debate, especially after the birth of a new subject, ‘national ethics’ in school education. Yet even nowadays, questions remain regarding whether the two systems of ethics are independent,complementary, or combinable in some way. I’m going to (...) propose a multi-layered structure of moral education; ‘ the three steps of Ethics’ for designing ethical system and moral education of South Korea. First, etiquette education, which is provided in the household prior to self-controlled critical thinking, will be discussed as an infrastructure of moral education. Then, one of the main purposes of schooling, moral thinking education will be described in terms ofdilemma model of organic form. Lastly, a long forgotten side of today’s moral education, the practical implications of ‘virtue education’, will be emphasized because of their cardinal importance to both Eastern and Western traditions.

Using a lens of cultural industry approach, this study explores the rise and fall of the political entertainment with a focus on specific moments associated with the trajectory of Korean political entertainment in public setting. A historical overview of Korean political entertainment traces back to the 1930s when Mandam, a unique kind of political satiric talk became popular in 1930s. Mandam played a satiric role in influencing public opinion on political affairs, particularly led by the early generation of Mandam storytellers. (...) Their criticism centered on Japanese colonial rule, even though Mandam was limited in terms of freedom of speech during this period. Furthermore, this study highlights that the great popularity of Mandam was driven by business organizations for the commercial purpose. Mandam was placed at the core of intricate relationships among the related industries. In sum, the present study concludes that as distinctive form blending political information and entertainment, Mandam played a vital role in expressing individuals‟ political opinions under the communicative circumstances during the Japanese colonial period.

The primary goal of this paper is to investigate the theoretical and methodological applicability of the relevant theories of Marcuse and Foucault to analyzing the relationship between comedic pleasure and the popular media. The researchers investigate the similarities of and the differences between the respective positions of Marcuse and Foucault as they relate to power relations, subjectivity, and practice. Likewise, the methodological applicability of these theorists’ work to a discourse analysis of how media content constructs comedic pleasure is considered. Overall, (...) the present study explored the arrangement and deployment of discourses of comedic pleasure as exploited by the power/knowledge mechanism of the media and the entertainment industry. And, through this discussion, the current study argued that three key statements constitute a discursive framework for the analysis of comedic pleasure in the popular media. (shrink)

Using a signaling framework, we argue that ethical behavior as evidenced by charitable donations is viewed more positively by investors when seen not to be based on self-serving motives but rather on authentic generosity that builds moral capital. The affirmed religiosity of CEOs may make their ethical position more credible, while their embeddedness within a family business suggests that CEOs are backed by powerful owners with long-time horizons and a desire to build moral capital with stakeholders. We find in a (...) study of market responses to 1572 corporate donations by S&P 1500 firms that financial markets react more positively to charitable initiatives from firms with religion-declared CEOs, but only if these are family businesses.
