The structure of the deep artificial neural network is similar to the structure of the biological neural network, which can be well applied to the 3D visual image recognition of aerobics movements. A lot of results have been achieved by applying deep neural networks to the 3D visual image recognition of aerobics movements, but there are still many problems to be overcome. After analyzing the expression characteristics of the convolutional neural network model for the three-dimensional visual image characteristics of aerobics, (...) this paper builds a convolutional neural network model. The model is improved on the basis of the traditional model and unifies the process of aerobics 3D visual image segmentation, target feature extraction, and target recognition. The convolutional neural network and the deep neural network based on autoencoder are designed and applied to aerobics action 3D visual image test set for recognition and comparison. We improve the accuracy of network recognition by adjusting the configuration parameters in the network model. The experimental results show that compared with other simple models, the model based on the improved AdaBoost algorithm can improve the final result significantly when the accuracy of each model is average. Therefore, the method can improve the recognition accuracy when multiple neural network models with general accuracy are obtained, thereby avoiding the complicated parameter adjustment process to obtain a single optimal network model.

BackgroundExperience with open disclosure and its study are restricted to certain western countries. In addition, there are concerns that open disclosure may be less suitable in non-western countries. The present study explored and compared the in-depth perceptions of the general public and physicians regarding open disclosure in Korea.MethodsWe applied the COREQ checklist to this qualitative study. We conducted 20 in-depth interviews and four focus group discussions with 16 physicians and 18 members of the general public. In-depth interviews and focus group (...) discussions were performed according to semi-structured guidelines developed according to a systematic review of open disclosure. We conducted a directed content analysis by analyzing the verbatim transcripts and field notes in accordance with the predetermined guidelines.ResultsOpen disclosure perceptions were summarized in terms of the “five Ws and one H”. All physician and general public participants acknowledged the normative justifiability of open disclosure. The participants mostly agreed on the known effects of open disclosure, but the physicians had negative opinions on its expected effects, such as decreased intention of the general public to file lawsuits and increased credibility of medical professionals. Generally, the participants thought that open disclosure is required for medical errors causing major harm. However, the physicians and general public had conflicting opinions on the need for open disclosure of near misses. Most physicians did not know how to conduct open disclosure and some physicians had bad experiences due to inappropriate or incomplete open disclosure.ConclusionPhysicians and the general public in Korea acknowledge the need for open disclosure. Guidelines according to the type of patient safety incident are required to encourage physicians to more readily conduct open disclosure. Furthermore, hospitals need to consider organizing a dedicated team and hiring experts for open disclosure. (shrink)

This paper is about activities of ‘community of inquiry’ on the basis of Lipman’s model applied at a kindergarten in Seoul, Korea. The activities of community of inquiry, basically, includes a series of activities, for example, reading textbooks, making up questions, discussing on themes, working out exercises and further responding. At the beginning of P4C lessons, young children had difficulties in reading texts with no pictures, and making up questions. Having philosophy lessons repeatedly, they were accustomed to the activities, felt (...) joy of thinking by themselves, and enjoyed dialoguing with friends and discussing together. The young children in the community of inquiry showed intimacy and curiosity about the stories written by Dr, Chung, which described typical Korean young child’s daily life and were full of situations experienced in their families and kindergartens. The young children were interested in inquiring philosophical aspects of the stories, tried to think by themselves like philosophers, and finally could achieve the goals of P4C, in short, to think by themselves, to cultivate ethical and aesthetic mind, and to harmonize with others.

This study assessed the knowledge and perception of human biological materials (HBM) and biorepositories among three study groups in South Korea. The relationship between the knowledge and the perception among different groups was also examined by using factor and regression analyses. In a self-reporting survey of 440 respondents, the expert group was found more likely to be knowledgeable and positively perceived than the others. Four factors emerged: Sale and Consent, Flexible Use, Self-Confidence, and Korean Bioethics and Biosafety Action restriction perception. (...) The results indicate that those who are well aware of the existence of biobanks were more positively inclined to receive the Sale and Consent perception. As a result of the need for high quality HBMs and the use of appropriate sampling procedures for every aspect of the collection and use process, the biorepository community should pay attention to ethical, legal, and policy issues.

This study investigates the effects of cultural orientation and the degree of disdain for robots on the preferred conversational styles in human-to-robot interactions. 203 participants self-reported on questionnaires through a computer-based online survey. The two requesting situations were intended to simulate the participants' interactions with humanoid social robots through an Internet video-phone medium of communication. Structural equation modeling was performed to examine the mediating role of mechanistic disdain between multicultural orientation and conversational constraints. The findings reveal that between the two (...) dimensions of multicultural orientation, only open-mindedness inversely influences mechanistic disdain. Mechanistic disdain, in turn, negatively affects three face-related conversational constraints, thereby leading to a lesser concern for robots' feelings, for minimizing impositions on robots, and for avoiding robots' negative evaluations. The implications of our findings on humans' relations with virtual robot entities and on the future development of humanoid robots are discussed. (shrink)

This paper aims to clarify and resolve issues surrounding the so-called formal linking problem in interpreting the Internally Headed Relative Clause construction in Korean and Japanese, a problem that has been identified in recent E-type pronominal treatments of the construction (e.g., Hoshi, K. (1995). Structural and interpretive aspects of head-internal and head-external relative clauses. PhD dissertation, University of Rochester; Shimoyama, J. (2001). Wh-constructions in Japanese. PhD dissertation, University of Massachusetts at Amherst). In the literature, this problem refers to the difficulty (...) of capturing the delimited semantic variability of the E-type pronoun present in the embedding clause of the construction. I show that the E-type pronoun at issue is subject to a different licensing condition from a typical E-type pronoun and therefore presents a different linking problem. More specifically, it requires that the embedded clause describe a state of its antecedent and its descriptive content be supplied by a salient property represented in the logical form of the embedded clause. I propose an event-based semantic analysis that derives the effects of this novel generalization by establishing a binding relation between the event structure of the embedded clause and the denotation of the E-type pronoun.

In April 2011, the Korea Centers for Disease Control and Prevention announced the results of an epidemiological investigation that an unknown cause of lung disease that occurred throughout Korea was caused by humidifier disinfectants. The unprecedented social catastrophe caused by humidifier disinfectants, a household chemical, has so far reported 1,784 deaths and 5,984 survivors in South Korea. This study was designed to investigate the multi-layer relationships between psychological symptoms and adaptive functioning in survivors of the Humidifier disinfectants in South Korea (...) caused by chemical toxic substances. Specifically, this study aimed to explore how psychological symptoms affect actual interpersonal relationships and job adjustment with two variable sets, six internalizing and externalizing subscales, and three adaptation subscales. A total of 224 survivors recruited from a program to support humidifier disinfectant survivors by the government participated in this study. This research was approved by the Institutional Review Board of one of the Universities in South Korea. The age range of the participants was 18–73 years, 37.1% were male, and 62.9% were female. The participants responded to the Adult Self-Report of the Achenbach System of Empirically Based Assessment. A Canonical Correlation Analysis generated three unique patterns in the relationships between psychological symptoms and adaptive functions. Humidifier disinfectant survivors in the first pattern were more vulnerable to psychological symptoms and showed maladaptive functioning in life. Survivors in the second pattern showed intrusive behaviors and appeared to be adaptive in relationships with friends. Finally, survivors in the third pattern showed aggressive behaviors and reported poor partner relationships while showing good relationships with friends. The practical implications of the interventions are also discussed. (shrink)

Robot enthusiasts envision robots will become a “race unto themselves” as they cohabit with the humankind one day. Profound questions arise surrounding one of the major areas of research in the contemporary world—that concerning artificial intelligence. Fascination and anxiety that androids impose upon us hinges on how we come to conceive of the “Cultural Other.” Applying the notion of the “other” in multicultural research process, we will explore how the “Other” has been used to illustrate values and theories about robots, (...) as a mirror for the self. In this paper, we focus on the social, cultural, and religious implications of humans’ attitudes toward relationships between humans with robots. Six major views on humanoid robots are proposed: (1) robots as the “Frightening Other,” (2) robots as the “Subhuman Other,” (3) robots as the “Human Substitute,” (4) robots as the “Sentient Other,” (5) robots as the “Divine Other,” and (6) robots as the “Co-evolutionary Path to Immortality.” The likely and preferable scenario is the last one, which is compatible with an optimistic posthuman world in our evolutionary future. We imagine whether humans will meet the challenge of loving all living and non-living beings (including mechanical entities) might be the key to the co-evolution of both species and the ultimate happiness.

Theories of ethical leadership provide important insights about the effect of leader’s ethics on the relationship between leaders and followers. However, there is an increasing demand for addressing key constructs that enhance the capacity to explain theoretical aspects of ethical leadership. The purpose of this study is to expand the theoretical framework of ethical leadership based on Korean traditional leadership by focusing on personal cultivation, morality, and social responsibility. Using a framework of intrapersonal process as leadership and core value and (...) competence as components of leadership, this study examines the ethical aspects of Korean traditional leadership and provides the implications to further develop the theory of ethical leadership. It is found that ethical integrity ensued from sugi is an essential precondition to develop leadership, and the core value of ethical leadership includes Zhixin-Chijing and the competence co..

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)

Computerized relaxation training has been suggested as an effective and easily accessible intervention for individuals with psychological distress. To better elucidate the neural mechanism that underpins the effects of relaxation training, we investigated whether a 10-session computerized relaxation training program changed prefrontal gamma-aminobutyric acid levels and cerebral blood flow in women with psychological distress. We specifically focused on women since they were reported to be more vulnerable to develop stress-related disorders than men. Nineteen women with psychological distress but without a (...) diagnosis of psychiatric disorders received the 10-day computerized relaxation training program that consisted of 30-min cognitive-relaxation training and 10-min breathing-relaxation training per day. At baseline and post-intervention, perceived stress levels, anxiety, fatigue, and sleep quality were assessed by self-report questionnaires. Brain magnetic resonance spectroscopy and arterial spin labeling scans were also performed before and after the intervention to evaluate GABA levels and relative CBF in the prefrontal region. Levels of perceived stress, anxiety, fatigue, and sleep quality improved following 10 sessions of computerized relaxation training, resulting in a significant relief in composite scores of stress-related symptoms. The prefrontal GABA levels decreased, while relative CBF increased after the intervention. In addition, a greater increase in relative prefrontal CBF was associated with better composite scores of stress-related symptoms following the intervention. The current findings suggest that computerized relaxation training may improve stress-related symptoms through modulating the prefrontal GABA levels and CBF in women with psychological distress.

Virtual reality is a rapidly developing technology that simulates the real world. However, for some cybersickness-susceptible people, VR still has an unanswered problem—cybersickness—which becomes the main obstacle for users and content makers. Sensory conflict theory is a widely accepted theory for cybersickness. It proposes that conflict between afferent signals and internal models can cause cybersickness. This study analyzes the brain states that determine cybersickness occurrence and related uncomfortable feelings. Furthermore, we use the electroencephalogram microstates and functional connectivity approach based on (...) the sensory conflict theory. The microstate approach is a time–space analysis method that allows signals to be divided into several temporarily stable states, simultaneously allowing for the exploration of short- and long-range signals. These temporal dynamics can show the disturbances in mental processes associated with neurological and psychiatric conditions of cybersickness. Furthermore, the functional connectivity approach gives us in-depth insight and relationships between the sources related to cybersickness. We recruited 40 males, and they watched a VR video on a curved computer monitor for 10 min to experience cybersickness. We recorded the 5-min resting state EEG and 10-min EEG while watching the VR video. Then, we performed a microstate analysis, focusing on two temporal parameters: mean duration and global explained variance. Finally, we obtained the functional connectivity data using eLoreta and lagged phase synchronization. We discovered five sets of microstates, including four widely reported canonical microstates, during baseline and task conditions. The average duration increased in microstates A and B, which is related to the visual and auditory networks. The GEV and duration decreased in microstate C, whereas those in microstate D increased. Microstate C is related to the default mode network and D to the attention network. The temporal dynamics of the microstate parameters are from cybersickness disturbing the sensory, DMN, and attention networks. In the functional connectivity part, the LPS between the left and right parietal operculum significantly decreased compared with the baseline condition. Furthermore, the connectivity between the right OP and V5 significantly decreased. These results also support the disturbance of the sensory network because a conflict between the visual and vestibular system causes cybersickness. Changes in the microstates and functional connectivity support the sensory conflict theory. These results may provide additional information in understanding brain dynamics during cybersickness.

This study explores the transhuman from an East Asian perspective. In terms of cognitive science, mathematics, and theology, we define the transhuman system as characterized by transcendence, extension by compactification, and samtaegeuk. Compactification is conceptualized here in mathematical terms, as adding one or more elements so that a system becomes more complete—as one might join both ends of a line, and thereby create a circle. We assert that the East Asian transhuman could be defined as a three-point compactification: as an (...) extension of biophysical objects and events such as robots, cyborgs, and environments ; as an extension of culture, science, and art ; and as an extension of the interaction between the human and Cosmic Absolute such as in religions. Such a notion of the Transhuman might be associated with God, but any description of God, the Absolute Infinite, will apply to something less than God. (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.
