Background: An association between gaming disorder and the symptoms of common mental disorders is unraveled yet. In this preregistered study, we quantitatively synthesized reliability, convergent and discriminant validity of GD scales to examine association between GD and other constructs.Methods: Five representative GD instruments were chosen based on recommendations by the previous systematic review study to conduct correlation meta-analyses and reliability generalization. A systematic literature search was conducted through Pubmed, Proquest, Embase, and Google Scholar to identify studies that reported information on (...) either reliability or correlation with related variables. 2,124 studies were full-text assessed as of October 2020, and 184 were quantitatively synthesized. Conventional Hedges two-level meta-analytic method was utilized.Results: The result of reliability generalization reported a mean coefficient alpha of 0.86 and a mean test-retest estimate of 0.86. Estimated effect sizes of correlation between GD and the variables were as follows: 0.33 with depression, 0.29 with anxiety, 0.30 with aggression, –0.22 with quality of life, 0.29 with loneliness, 0.56 with internet addiction, and 0.40 with game playtime, respectively. The result of moderator analyses, funnel and forest plots, and publication bias analyses were also presented.Discussion and Conclusion: All five GD instruments have good internal consistency and test-retest reliability. Relatively few studies reported the test-retest reliability. The result of correlation meta-analysis revealed that GD scores were only moderately associated with game playtime. Common psychological problems such as depression and anxiety were found to have a slightly smaller association with GD than the gaming behavior. GD scores were strongly correlated with internet addiction. Further studies should adopt a rigorous methodological procedure to unravel the bidirectional relationship between GD and other psychopathologies.Limitations: The current study did not include gray literature. The representativeness of the five tools included in the current study could be questioned. High heterogeneity is another limitation of the study.Systematic Review Registration: [https://www.crd.york.ac.uk/PROSPERO/], identifier [CRD42020219781]. (shrink)

Human behavior is frequently described both in abstract, general terms and in concrete, specific terms. We asked whether these two ways of framing equivalent behaviors shift the inferences people make about the biological and psychological bases of those behaviors. In five experiments, we manipulated whether behaviors are presented concretely (i.e. with reference to a specific person, instantiated in the particular context of that person’s life) or abstractly (i.e. with reference to a category of people or behaviors across generalized contexts). People (...) judged concretely framed behaviors to be less biologically based and, on some dimensions, more psychologically based than the same behaviors framed in the abstract. These findings held true for both mental disorders (Experiments 1 and 2) and everyday behaviors (Experiments 4 and 5) and yielded downstream consequences for the perceived efficacy of disorder treatments (Experiment 3). Implications for science educators, students of science, and members of the lay public are discussed. (shrink)

This study assessed the demographic characteristics of Koreans engaged in leisure sports activities during the COVID-19 pandemic and the differences in their preventive health behaviors and constraints on leisure activities. For this study, the demographic characteristics of 544 leisure sport participants, who were recruited on a nationwide basis, were examined through an online survey. Then, comparisons between groups were performed using independent t-tests, one-way analysis of variance, and multivariate analysis of variance. Women who participated in both indoor and outdoor leisure (...) sports showed higher adoption of health prevention behaviors than their male counterparts, and married individuals who participated in indoor leisure sports showed higher adoption of health prevention behaviors than unmarried participants. Moreover, individuals who participated in both indoor and outdoor leisure sports by themselves had many interpersonal constraints overall, and the group of married individuals who participated in indoor leisure sports showed structural constraints. In conclusion, leisure sports participants have adopted many health prevention behaviors during the COVID-19 pandemic, but this had led to some interpersonal constraints. These results indicate that, in the case of future pandemics, personal and institutional efforts will need to be made to promote participation in leisure sports and prevent excessive social isolation.

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.

Background: Infectious disease outbreaks such as COVID-19 and MERS pose a major threat to healthcare workers' physical and mental health. Studies exploring the positive changes gained from adapting to traumatic events, known as post-traumatic growth, have attracted much attention. However, it is unclear which factors or experiences lead to PTG among HCWs. The purpose of this mixed-method study was to investigate factors associated with PTG among HCWs who experienced the MERS outbreak in South Korea, and fully describe their experience of (...) developing PTG.Methods: Quantitative data from 78 participants were collected using psychometric tools for Psychological distress, Resilience, and Support for coping, and Post-traumatic growth. Qualitative interviews were conducted with seven nurses. Data were analyzed using the qualitative content analysis method according to the sub-themes of resilience, which was the main factor associated with PTG.Results: We found resilience to have a significant impact on PTG. Thus the qualitative interviews were analyzed using the core concepts of resilience. Qualitative interviews with nurses illustrated how participants experienced the development of resilience in terms of its sub-factors: hardiness, persistence, optimism, and support.Conclusion: HCWs who endured the MERS outbreak showed high levels of PTG, and the analysis of the interview data provided a fuller understanding on the experience of remaining resilient and developing PTG. These results provide practical and pragmatic information helpful for developing intervention strategies and protocols that can help HCWs transform adversity into growth and development. (shrink)

The role of government in East Asian economic development has been a contentious issue. Two competing views have shaped enquiries into the source of the rapid growth of the high-performing Asian economies and attempts to derive a general lesson for other developing economies: the market-friendly view, according to which government intervenes little in the market, and the developmental state view, in which it governs the market. What these views share in common is a conception of market and government as alternative (...) mechanisms for resource allocation. They are distinct only in their judgement of the extent to which market failures have been, and ought to be, remedied by direct government intervention. This collection of essays suggests a breakthrough, third view: the market-enhancing view. Instead of viewing government and the market as mutually exclusive substitutes, it examines the capacity of government policy to facilitate or complement private sector co-ordination. The book starts from the premiss that private sector institutions have important comparative advantages over government, in particular in their ability to process information available on site. At the same time, it recognizes that the capabilities of the private sector are more limited in developing economies. The market-enhancing view thus stresses the mechanisms whereby government policy is directed at improving the ability of the private sector to solve co-ordination problems and overcome other market imperfections. In presenting the market-enhancing view, the book recognizes the wide diversity of the roles of government across various East Asian economiesincluding Japan, Korea, Hong Kong, Malaysia, and China and its path-dependent and developmental stage nature.

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)

While social interaction and play in a VR environment are becoming ever more popular, little is known about how social VR games affect users. The purpose of this study was to elucidate the role of several contingent factors in social VR games by modeling the relationships between involvement, well-being, depression, self-esteem, and social connectedness. A conditional process-moderated mediation model of the measured variables was analyzed with 220 pieces of collected data. The result showed that: the direct effect of involvement on (...) well-being was significant, and the index of moderated mediation involving depression, self-esteem, and social connectedness was significant. We conclude that high levels of involvement in social VR games by socially isolated users with low self-esteem can negatively affect their well-being. The findings of this study contribute in several ways to our understanding of the effect of social VR games upon users and provide important practical implications. (shrink)

Efficient management of low energy states is vital for cells to maintain basic functions and metabolism and avoid cell death. While autophagy has long been considered a critical mechanism for ensuring survival during energy depletion, recent research has presented conflicting evidence, challenging the long‐standing concept. This recent development suggests that cells prioritize preserving essential cellular components while restraining autophagy induction when cellular energy is limited. This essay explores the conceptual discourse on autophagy regulation during energy stress, navigating through the studies (...) that established the current paradigm and the recent research that has challenged its validity while proposing an alternative model. This exploration highlights the far‐reaching implications of the alternative model, which represents a conceptual departure from the established paradigm, offering new perspectives on how cells respond to energy stress.

This paper explores the question of embodiment/disembodiment discussed by Hwa Yol Jung mainly in his recent work, Rethinking Political Theory (1993a) in tandem with an examination of some recent developments in Korean scholarship on the same subject. To sum up, the following three points are emphasized. First, this living body does not exist except in specific modalities. In this sense, Gabriel Marcel''s paradigmatic affirmation that I am my body requires an elaboration of the specific modalities of the living body as (...) a being in the world. Second, the way a living body exists is not exclusively mental or physical, but both. In short, it is phenomenal. Third, the point of the whole argument can be summed up as follows: to conceal one''s own body is natural, but to forget it is dangerous. The primary task of phenomenology is not to denude human beings, but to reawaken ourselves to the idea that we are beings who live with and through bodies. (shrink)

This study investigates: the changes in three major health-related factors—physical activity, non-physical-activity health behavior, and depressive symptoms, and how changes in physical activity were associated with changes in one’s depressive symptoms among young adults, middle-aged adults, and older adults while controlling non-physical-activity health behavior and sociodemographic characteristics among young, middle-aged, and older adults before and after the COVID-19 outbreak lockdown in the United States. A total of 695 participants completed an online questionnaire via MTurk, and participants were asked to recall (...) their physical activity, depressive symptoms, and non-physical-activity health behavior status in January and May of 2020. The IPAQ-SF was used to evaluate individuals’ physical activity, while the CES-D-10 was used to assess depressive symptoms. Covariates included non-physical-activity health behavior and sociodemographic factors. A Bayesian significance testing of changes was used to examine significant changes in physical activity, non-physical-activity behavior, and depressive symptoms in each age group while Bayesian regression analysis was employed to examine how the changes in physical activity were associated with respondents’ depressive symptoms while controlling for individual NHB and sociodemographic characteristics. The results showed that the participants tended to maintain their physical activity levels after the lockdown despite significant increases in sitting time among young and older adults. Decreases in moderate physical activity frequency were associated with a higher level of depressive symptoms. Although young and middle-aged cohorts experienced fewer differences in depressive symptoms compared to their counterparts in the older group, we found no significant heterogeneity effects in the relationships of interest across all age groups. Considering different influences of physical activity on depressive symptoms depending on different levels of activity and ages, more randomized clinical trials with program-based intervention studies should be conducted with different physical activity programs for different age populations.

The result of 2007’s presidential election in South Korea symbolizes the decline of the Left and the growth of the new Right. They say it goes with the global retrogression of democracy, or the consolidation of the hegemony of the rightist versions of democracy. According to Choi Jang-jip, the general public in Korea has thought that the Roh Moo-hyun’s administration had betrayed them, handing power over to the market, and seeking to form a coalition government with theconservatives. Similarly, Professor Jang (...) Ha-jun asserts that the democratic governments of Kim Dae-jung and Roh Moo-hyun have mistaken economic democratization for neo-liberalistic structural adjustment.

본 논문은 에마뉘엘 레비나스(Emmanuel Levinas)와 주디스 버틀러(Judith Butler)를 종합적이고도 전면적으로 대면하려는 기획의 첫 번째 작업으로서, 레비나스에 대한 버틀러의 이해를 살피는 데 목적이 있다. 윤리 담론이 급진적인 정치 이론에서 수행하는 역할에 대해 회의적이었던 초기의 입장과 달리, 버틀러는 2000년 이후의 저작에서부턴 본격적으로 윤리를 정치적 문제의 중심에, 비판적 이론의 중심에 두고 자신의 사유를 전개해나간다. 이때 그녀가 참조한 대표적인 철학자가 레비나스다. 버틀러가 레비나스를 따라 윤리를 강조한다고 해서, 즉 그녀의 소위 ‘윤리로의 전환’이 정치의 포기나 도덕 만능주의를 의미하는 것은 결코 아니다. 버틀러에서 윤리는 정치의 대체물 혹은 (...) 대립물이 아니다. 그녀는 정치를 떠나 윤리로 이동하려한 것이 아니다. 도리어 그녀는 윤리를 통해 정치로 나아가려 한다. 레비나스에 대한 버틀러의 관심도 정확히 이에 값한다. 버틀러는 레비나스 철학의 핵심 개념 중 하나로 ‘얼굴’ 개념을 지목하고 이를 자신이 강조하는 ‘의존성’, ‘불확실성’, ‘취약성’ 개념과 연결 지을 뿐 아니라, 그녀 자신이 ‘유대주의적 비폭력의 윤리’라 명명한 것의 의미를 구체화하는 데 활용하고자 한다. 그렇다고 버틀러가 레비나스의 사유에 동의하기만 한 것은 아니다. 오히려 그 반대다. 버틀러는 레비나스가 강조하는 타자의 얼굴을, 그러니까 고유하고 대체 불가능한 그 특성을 현실 속의 타자로 정치화하고 그럼으로써 레비나스 사유의 한계를, 더 정확히는 레비나스가 어떻게 그 자신을 배반하게 되는지를 보여주려 한다.BR 레비나스에 대한 버틀러의 이해와 전유를, 또 이를 관통하는 버틀러의 기획과 그녀의 새로운 정치철학을 이 짧은 한 편의 논문에서 모두 다루기는 어려울 것이다. 그리하여 본 논문에서는 레비나스에 대한 버틀러의 이해를 확인하는 데 집중하기로 한다. 구체적으로는 얼굴, 주체와 타자의 관계로서의 책임, 레비나스의 문제, 이 3가지 주제에 대한 버틀러의 사유를 확인할 것이다. 이런 일은 레비나스에 대한 버틀러의 주된 인식을, 또 거기서 변화 발전하는 버틀러의 입장을 이해하는 데 도움이 될 것이며, 종국적으로는 버틀러의 사유에서 레비나스가 차지하는 위치, 그러니까 레비나스 윤리학을 통한 그녀의 정치철학의 면모를 확인하는 데 기여할 것이다.

The main purpose of this study was to investigate the impact of perceived HR practices on affective commitment and turnover intention. This study explored which HR practices were relatively more important in predicting affective commitment and turnover intention. A total of 302 employees from the United States and 317 from South Korea completed the same questionnaires for assessing the aforementioned relationships. The results illustrated that among perceived HR practices, internal mobility had the most significant association with turnover intention in both (...) the US and South Korea. While internal mobility was a stronger predictor of affective commitment for the US sample, training was the most important variable for predicting affective commitment in South Korea. The second purpose of the study was to examine whether individuals’ positive affect influences the relationship between perceived HR practices and affective commitment and turnover intention. In the US, positive affect moderated the relationship between perceived HR practices and affective commitment and turnover intention such that the relationships were stronger for individuals reporting high positive affect relative to those reporting low positive affect. However, these relationships were not significant in South Korea. We discuss the implications of these results, study limitations, and practical suggestions for future research. (shrink)

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)

Does the Ship of Theseus present a genuine puzzle about persistence due to conflicting intuitions based on “continuity of form” and “continuity of matter” pulling in opposite directions? Philosophers are divided. Some claim that it presents a genuine puzzle but disagree over whether there is a solution. Others claim that there is no puzzle at all since the case has an obvious solution. To assess these proposals, we conducted a cross-cultural study involving nearly 3,000 people across twenty-two countries, speaking eighteen (...) different languages. Our results speak against the proposal that there is no puzzle at all and against the proposal that there is a puzzle but one that has no solution. Our results suggest that there are two criteria—“continuity of form” and “continuity of matter”— that constitute our concept of persistence and these two criteria receive different weightings in settling matters concerning persistence.

The purpose of this study is to investigate the relationships among corporate social responsibility (CSR), corporate brand credibility, corporate brand equity, and corporate reputation. Structural equation modeling analysis provided support for the hypotheses from a sample of 867 consumers in South Korea. The results showed that CSR has a direct positive effect on corporate brand credibility and corporate reputation. In addition, the results indicate that corporate brand credibility mediates the relationship between CSR and corporate reputation. Moreover, corporate brand credibility mediates (...) the relationship between CSR and corporate reputation. Finally, the relationship between CSR and corporate brand equity is sequentially and fully mediated by corporate brand credibility and corporate reputation. The theoretical and managerial implications of the results and limitations are discussed, and future research directions are suggested. (shrink)
