Artificial intelligence techniques in general and convolutional neural networks in particular have attained successful results in medical image analysis and classification. A deep CNN architecture has been proposed in this paper for the diagnosis of COVID-19 based on the chest X-ray image classification. Due to the nonavailability of sufficient-size and good-quality chest X-ray image dataset, an effective and accurate CNN classification was a challenge. To deal with these complexities such as the availability of a very-small-sized and imbalanced dataset with image-quality (...) issues, the dataset has been preprocessed in different phases using different techniques to achieve an effective training dataset for the proposed CNN model to attain its best performance. The preprocessing stages of the datasets performed in this study include dataset balancing, medical experts’ image analysis, and data augmentation. The experimental results have shown the overall accuracy as high as 99.5% which demonstrates the good capability of the proposed CNN model in the current application domain. The CNN model has been tested in two scenarios. In the first scenario, the model has been tested using the 100 X-ray images of the original processed dataset which achieved an accuracy of 100%. In the second scenario, the model has been tested using an independent dataset of COVID-19 X-ray images. The performance in this test scenario was as high as 99.5%. To further prove that the proposed model outperforms other models, a comparative analysis has been done with some of the machine learning algorithms. The proposed model has outperformed all the models generally and specifically when the model testing was done using an independent testing set. (shrink)

The cognitive unbinding paradigm suggests that the synthesis of neural information is attenuated by general anesthesia. Here, we analyzed the functional organization of brain activities in the conscious and anesthetized states, based on functional segregation and integration. Electroencephalography recordings were obtained from 14 subjects undergoing induction of general anesthesia with propofol. We quantified changes in mean information integration capacity in each band of the EEG. After induction with propofol, mean information integration capacity was reduced most prominently in the γ band (...) of the EEG . Furthermore, we demonstrate that loss of consciousness is reflected by the breakdown of the spatiotemporal organization of γ waves. We conclude that induction of general anesthesia with propofol reduces the capacity for information integration in the brain. These data directly support the information integration theory of consciousness and the cognitive unbinding paradigm of general anesthesia. (shrink)

Frontoparietal connectivity has been suggested to be important in conscious processing and its interruption is thought to be one mechanism of general anesthesia. Data in animals demonstrate that feedforward processing of information may persist during the anesthetized state, while feedback processing is inhibited. We investigated the directionality and functional organization of frontoparietal connectivity in 10 human subjects anesthetized with propofol on two separate occasions. Multichannel electroencephalography and a computational method of assessing directed functional connectivity were employed. We demonstrate that directed (...) feedback connectivity is diminished with loss of consciousness and returns with responsiveness to verbal command. We also applied the Dendrogram classification method to assess the global organization of directed functional connectivity during consciousness and anesthesia. We demonstrate a state-specific hierarchy and subject-specific subhierarchy in functional organization. These data support the hypothesis that specific states of human consciousness are defined by specific states of frontoparietal connectivity. (shrink)

Service providers working for a service organization are asked to express such positive emotions as joy, pleasure, and politeness required at the organizational level rather than their natural emotions they are experiencing at the moment. They cannot express their emotion they are actually going through and accordingly, their level of emotional labor and emotional dissonance influence on their job commitment and trust toward their organization. This study thus set out to investigate the effects of leading variables of emotional labor on (...) the level of emotional labor and the impact of emotional labor on organizational trust and organizational commitment with a subject group of college administrative staffs. Three underlying factors such as job stress, intimacy, and professionalism were identified as the determinants of emotional labor. Conceptual background about job stress, intimacy, emotional labor, and organizational effectiveness as the core variables of the study was investigated. Based on the conceptual background and our research questions, 5 research hypotheses and the proposed research model regarding the effects of emotional labor on organizational commitment and trust were developed. We also tried to include the moderating effects of work environment and gender of service providers on the research model. Unlike many different studies on emotional labor from the traditional perspective of service, this study also offers a practical implication by expanding and applying it to the field of college administrative service, which is an area where service providers are in the different working environment from the traditional company work environment. Finally, the managerial implications and the limitations of the study were also discussed. (shrink)

Environmental, social, and governance is an indicator that measures a company’s non-financial performance. Many firms have recently emphasized the importance of ESG. Ascertaining what topics are being discussed around ESG and how they change over time will contribute significantly to gaining insight into ESG. Using 73,397,870 text data scraped and refined from publicly available Twitter data, this study applied Latent Dirichlet Allocation and the dynamic topic model to ascertain the hidden structure of the ESG-related document collection and the topics being (...) discussed. The study further conducts a sentiment analysis to examine the sentiment of the general public regarding ESG. Topic modeling shows that various topics regarding ESG are being discussed and evolve over time. Sentiment analysis shows that many people have neutral or positive sentiments toward ESG-related issues. This study contributes to exploring insights into ESG among the public and understanding public reactions toward ESG. We further conclude the study with a discussion of managerial implications and potential future research. (shrink)

The redemption thesis assumes that how events in a person’s life are related to one another is important in evaluating the person’s welfare throughout life. In particular, according to this thesis of welfare, the fact that a person’s previous hardships contribute to bringing out the same person’s later successes, and the person would regard the hardships as having been worthwhile in light of the successes makes the person’s life better for the person herself. Recently, Ian D. Dunkle provided four objections (...) to the redemption thesis: the intuition concern, the different redemptions argument, the downplaying hardships argument, and the reconciled irreconcilables argument. This paper examines these four objections. In particular, this paper dismisses all the objections showing that the redemption thesis bases on an appealing idea, does not consider the degree of hardship significant in itself, has plausible reasons to evaluate hardships not as serious as people think, and can successfully reconcile its synchronic and diachronic evaluations.

Jeong Jae-gyu (鄭載圭, 1843-1911) was a scholar in the late Joseon Dynasty who contributed to the solidification and formation of the Nosa school (蘆沙學派) through the publication of Nosajib (蘆沙集) and active lecture activities based on the independent acceptance of his teacher, Ki Jeong-jin (奇正鎭). He explained the concept of intelligence based on the definitions of Shen Gui-bao (沈貴珤), an early scholar of the Yuan Dynasty, and even though the volume was not large, he presented a deep analysis and a (...) unique interpretation. Few Joseon Neo-Confucian scholars had explained the concept of intelligence based on Shen Gui-bao, so his attempts are unique. Shen Gui-bao explained, “the Intelligence includes the axis of change in the real world where the heavenly principles are inherent and has a mirror to judge the conflicts of human affairs”. Hu Bing-wen (胡炳文) used the explanation to justify his concept of intelligence. However, since intelligence is a principle, and the “axis of change in the real world” is also a principle, an unreasonable proposition of ‘principle includes principle’ can be established according to Shen Gui-bao’s definitions. Therefore, Kim Chang-hyeop (金昌協) and others criticized Shen Gui-bao, saying that such a proposition cannot be accepted. However, in the 19th century, Lee Hang-ro (李恒老) and Lee Jin-sang (李震相) showed a positive attitude toward Shen Gui-bao’s definitions. Jeong Jae-gyu, who partially accepted the influence of Lee Jin-sang, reaffirmed the fundamental position of intelligence through the phrase “Intelligence includes the axis of change in the real world”, and emphasized that intelligence is the basis for both moral judgment and the principle of perception. Furthermore, in the Neo-Confucian system, intelligence corresponds to a quiet virtue, so Jung Jae-gyu’s emphasis on it might lead to a theory of cultivation centered on solitude (靜), which can be confirmed in questions and answers shared with Ki Jung-jin, his writings, and poems.

This paper deals with two different problems in which infinity plays a central role. I first respond to a claim that infinity renders counting knowledge-level beliefs an infeasible approach to measuring and comparing how much we know. There are two methods of comparing sizes of infinite sets, using the one-to-one correspondence principle or the subset principle, and I argue that we should use the subset principle for measuring knowledge. I then turn to the normalizability and coarse tuning objections to fine-tuning (...) arguments for the existence of God or a multiverse. These objections center on the difficulty of talking about the epistemic probability of a physical constant falling within a finite life-permitting range when the possible range of that constant is infinite. Applying the lessons learned regarding infinity and the measurement of knowledge, I hope to blunt much of the force of these objections to fine-tuning arguments. (shrink)

It has long been believed across languages that the Agent‐First strategy, a comprehension heuristic that maps the first noun onto the agent role, is a general cognitive bias which applies automatically and faithfully to children's comprehension. The present study asks how this strategy interplays with such grammatical cues as the number of overt arguments and the presence of case‐marking in Korean, an SOV language with case‐marking by dedicated markers. To investigate whether and how these cues affect the operation of this (...) strategy, we measure children's comprehension of a transitive construction (with scrambling and omission of sentential components) in a novel experimental setting where arguments and case markers were obscured to varying degrees through acoustic masking. We find that children do not demonstrate the agent‐first interpretation strongly in the noun–verb pattern without case‐marking, showing their uncertainty about the thematic role of the nominal when it is both the only argument in the sentence and lacks case‐marking. They perform significantly better in the patterns with additional cues, the impact of which is asymmetric by age and by the nature of alignment between cues from word order and case‐marking. These findings suggest that, for Korean‐speaking children's comprehension of a transitive construction, the Agent‐First strategy is activated properly only in conjunction with other types of interpretive cues.

Simion and Kelp explain the trustworthiness of an AI based on that AI’s disposition to meet its obligations. Roughly speaking, according to Simion and Kelp, an AI is trustworthy regarding its task if and only if that AI is obliged to complete the task and its disposition to complete the task is strong enough. Furthermore, an AI is obliged to complete a task in the case where the task is the AI’s etiological function or design function. This account has a (...) strength in that it can provide a unificatory rationale for the trustworthy-making properties of AIs. According to this account, being explainable, being safe, and being transparent are the trustworthy-making properties of an AI because an AI can fulfill its etiological or design functions in the case where it is explainable, safe, and transparent. This paper shows that though Simion and Kelp’s account has a strength, this account is not satisfactory for two reasons. The first reason is that an AI’s trustworthiness is not determined just by the AI’s disposition to meet obligations, and the second reason is that it is difficult to explain how an AI’s etiological function and design function have to do with that AI’s obligations. To provide a full-fledged account, Simion and Kelp should dismiss these concerns. (shrink)

When Western Christianity came to Asia, it merged with Eastern religions and histories and developed very differently in different places. Today Asian women in each country build up very unique images of God. They practice Eastern forms of worship and liturgical rites, and do indigenized theologies. They simultaneously try to find their own ways of naming, imaging, believing in and communicating with their own God. Korean Christianity has inherited many images of God from Western Christian doctrines and theologies. However, when (...) it meets and merges with Koreanized Buddhism, Confucianism, and Shamanism, some of the images of God in Christianity are transformed and re-imagined in Korean women's social cultural and religious contexts. As an Asian woman, especially a Korean woman, I would like to introduce one of the many Asian women's theologies, Korean women's images of God. It cannot represent all Asian women's ways of doing theologies, but it will give some clues to show how Asian women do theologies in their own context. In particular, I will examine three images of God that demonstrate how Western Christianity and Eastern religions meet and are transformed in Korean Christian women's living contexts. (shrink)

The Plight of Humanity in Paul In Paul and Palestinian Judaism, E. P. Sanders argues that, for Paul, humanity’s plight was not the condition that necessitated the solution of Jesus Christ. Instead, the solution was presented to Paul first on the Damascus road, and humanity’s plight was simply the logical corollary to the solution. This study will critically examine the particulars of Sanders’s argument— particularly with regard to Romans 7, Philippians 3, and Galatians 3—and offer some alternative exegetical analyses. This (...) essay will argue that, while the development of Paul’s thinking may indeed have run from solution to plight, the exposition of Paul’s thinking goes from plight to solution. The movement of Paul’s exposition may suggest that his conception of the plight of humanity was born out of his ideational milieu, which must have been fed, at least, by the Old Testament and evidenced, at least, by literature such as 4 Ezra.

This book investigates the different meanings and logics that the notion of qi/gi has acquired within the East Asian traditions in order to understand the diversity of these traditions. More specifically, this work focuses on investigating how the notion was understood by traditional Chinese and Korean philosophers.

Family disputes over the diagnosis of brain death have caused much controversy in the bioethics literature over the conceptual validity of the brain death standard. Given the tenuous status of brain death as death, it is pragmatically fruitful to reframe intractable debates about the metaphysical nature of brain death as metalinguistic disputes about its conceptual deployment. This new framework leaves the metaphysical debate open and brings into focus the social functions that are served by deploying the concept of brain death. (...) In doing so, it highlights the epistemic injustice of medicolegal authorities that force people to uniformly accept brain death as a diagnosis of death based on normative considerations of institutional interests, such as saving hospital resources and organ supplies, rather than empirical evidence of brain death as death, which is insufficient at best and nonexistent at worst. In light of this injustice, I propose the rejection of the uniform standard of brain death in favor of a choice-based system that respects families’ individualized views of death. (shrink)
