Purpose: The neural processing of children with overweight/obesity (CWO), may affect their eating behavior. We investigated the visual information processing of CWO under response control condition, by event-related potential (ERP) study, an electrophysiologic study for cognitive mechanism. Methods: Seventeen CWO (mean age: $10.6{\pm}1.9$), and 17 age-matched non-obese children (NOC), participated in the study. Neurocognitive function tests and visual ERP under Go/NoGo conditions, were implemented. Area amplitudes of major ERP components (P1, N1, P2, N2, and P3) from four scalp locations (frontal, central, parietal, and occipital), were analyzed. Results: For Go and NoGo conditions, CWO had significantly greater occipital P1, frontocentral N1, and P2 amplitudes compared with NOC. P2 amplitude was significantly greater in CWO, than in NOC, at the frontal location. N2 amplitude was not significantly different, between CWO and NOC. For CWO and NOC, Go P3 amplitude was highest at the parietal location, and NoGo P3 amplitude was highest at the frontal location. In Go and NoGo conditions, P3 amplitude of CWO was significantly less than in NOC. Conclusion: The greater P1, N1, and P2 suggested hyper-vigilance to visual stimuli of CWO, but the smaller P3 suggested insufficient mental representation of them. Such altered visual processing, may affect the eating behavior of CWO.
Purpose - The break-even point refers to the point where total profit and total cost coincide, and from this point on, the entrepreneur's decision-making takes a different route. Strategic decisions can be made for more efficient operation and eventually for more likelihood for growth and sustainability if a startup figures out when it recoups the investment and switches to a net profit. Design/methodology/approach - 748 creativity and skill-based sole proprietors in manufacturing industry were examined to demonstrate the effect of the entrepreneur's entrepreneurial experience and education level, the business launch preparation time, or the self-financing on the achievement of break-even point. Findings - While the business launch preparation time lowered the likelihood of reaching a break-even point, self-financing increased the likelihood. As a result of further analysis by subdividing into subgroups according to skill level, only the business launch preparation time was statistically significant in the highly skilled industries. In the low skilled industries, in addition to the business launch preparation time, the CEO's education level and the self-financing were statistically significant. Research implications or Originality - The longer the business launch preparation time, the higher the start-up cost, which increases the burden of initial cost recovery, and the agile response to market changes is thereby delayed, resulting in the business idea losing its appeal. Self-financing not only provides stability and strong motivation for the business operation but also promotes careful spending which contributes to the achievement of break-even point. In particular, it is found that practical experience is more useful than theoretical knowledge in low skilled industries. Due to the limitation of secondary data based on the recollection, the time required to reach a break-even point, percentage of financing sources, etc. may include cognitive errors. In addition, variables are not included that explain the characteristics of creativity and skill-based sole proprietorship, so it is necessary to exercise caution with the actual application.

Alzheimer's disease (AD) is a neurodegenerative disease with progressive memory loss and the cognitive decline. AD is mainly caused by abnormal accumulation of misfolded amyloid β (Aβ), which leads to neurodegeneration via a number of possible mechanisms such as down-regulation of brain-derived neurotrophic factor-tropomyosin-related kinase B (BDNF-TRKB) signaling pathway. 7,8-Dihydroxyflavone (7,8-DHF), a TRKB agonist, has demonstrated potential to enhance BDNF-TRKB pathway in various neurodegenerative diseases. To expand the capacity of flavones as TRKB agonists, two natural flavones quercetin and apigenin, were evaluated. With tryptophan fluorescence quenching assay, we illustrated the direct interaction between quercetin/apigenin and TRKB extracellular domain. Employing Aβ folding reporter SH-SY5Y cells, we showed that quercetin and apigenin reduced Aβ-aggregation, oxidative stress, caspase-1 and acetylcholinesterase activities, as well as improved the neurite outgrowth. Treatments with quercetin and apigenin increased TRKB Tyr516 and Tyr817 and downstream cAMP-response-element binding protein (CREB) Ser133 to activate transcription of BDNF and BCL2 apoptosis regulator (BCL2), as well as reduced the expression of pro-apoptotic BCL2 associated X protein (BAX). Knockdown of TRKB counteracted the improvement of neurite outgrowth by quercetin and apigenin. Our results demonstrate that quercetin and apigenin are to work likely as a direct agonist on TRKB for their neuroprotective action, strengthening the therapeutic potential of quercetin and apigenin in treating AD.

There is a need to develop an app for a caregiver health management that can provide continuous management in response to changes over time, because elderly people have low digital utilization capabilities, difficulty maintaining regular and continuous self-management. Based on this need, this study designed an app with a user-friendly UI and simple structure for the elderly. The app developed in this study supports regular management of health data such as blood pressure, blood sugar, and heart rate, as well as specific information on physical, disease, cognitive, communication, and environment in the care field. The app developed in this study supports care services by automatically entering data through integration with health management devices, automatically analyzing and visually representing recorded data to understand trends and volatility, and adding scalability to connect with various health management and medical support platforms. The effectiveness and satisfaction of the developed app were confirmed to be significant in the field verification results.

In this study, we investigated students' responses to a discrepant event and an alternative hypothesis which had been presented in the conceptual change processes from the phlogiston theory to the oxygen theory, and compared them with scientists' responses. The data concerning scientists' responses to the discrepant event and the alternative hypothesis were gathered from the relevant literature on the history of science. Subjects were 148 eighth graders who possessed the target misconception about combustion through a preconception test. After having been presented with the discrepant event and the alternative hypothesis, students were asked to respond to the test of response to discrepant event. Although similar types of responses were obtained from both scientists and students, there was also a clear difference. Scientists tended to focus on explaining the problems of the discrepant event, whereas students tended to ignore and/or exclude the discrepant event in order to maintain their previous beliefs. Only a few students were also found to change their beliefs after having been presented with the alternative hypothesis.
The geriatric patients with chronic physical diseases are frequently associated with the continuous clusters of depression including nonpathological sadness, subsyndromal depression, minor depressive disorder, and major depressive disorder. Because of the complex and reciprocal relationships among depression, elderly, and chronic physical diseases, screening approaches with specific nosological methods should be needed in the realm of early detection of depression. Cognitive decline is frequently manifested in geriatric depression with medical or neurological diseases. Also, somatic symptoms of depression or emotional symptoms of physical diseases can play a role as a hampering factor in the early detection of depression. Furthermore, after-care has been regarded as an essential factor of depression screening in the geriatric patients with chronic physical diseases. We reviewed the most popular examples of integrated medicine for depression in primary care. Thus, we propose a general hospital-based model for early detection of depression which includes favorable response loop between screening and therapeutic intervention. Our model can be a basis for evidence-based detection and after-care for depression in the geriatric patients with chronic medical diseases.

Alzheimer's disease (AD) is a chronic and progressive neurodegenerative disease that can be described by the occurrence of dementia due to a decline in cognitive function. The disease is characterized by the formation of extracellular and intracellular amyloid plaques. Amyloid beta (Aβ) is a hallmark of AD, and microglia can be activated in the presence of Aβ. Activated microglia secrete pro-inflammatory cytokines. Furthermore, S100A9 is an important innate immunity pro-inflammatory contributor in inflammation and a potential contributor to AD. This study examined the effects of metformin and α-LA on the inflammatory response and NLRP3 inflammasome activation in Aβ- and S100A9-induced BV-2 microglial cells. Metformin and α-LA attenuated inflammatory cytokines, such as tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). In addition, metformin and α-LA inhibited the phosphorylation of JNK, ERK, and p38. They activated the nuclear factor kappa B (NF-κB) pathway and the NOD-like receptor pyrin domain containing 3 (NLRP3) inflammasome. Moreover, metformin and α-LA reduced the marker levels of the M1 phenotype, ICAM1, whereas the M2 phenotype, ARG1, was increased. These findings suggest that metformin and α-LA are therapeutic agents against the Aβ- and S100A9-induced neuroinflammatory responses.
Purpose - There have been numerous studies investigating the effects of corporate social responsibility initiatives on corporate associations or corporate images. In line of this research stream, current research examined the potential impact of customer participation in the process of corporate social responsibility initiatives on attitude toward the company. This research differentiates from previous studies that it is the first to connect corporate social responsibility and customer participation. Specifically, we suggest a structural model on corporate associations which was classified into corporate ability associations and corporate social responsibility associations that the more the customers participate in initiating corporate social responsibility, corporate associations were formed more positively. And this leads to the increase of revisit intentions through customer satisfaction. Research design, data, and methodology - To test our research model, we collected data of real consumers of a large discount store in Korea. At the large discount store, customers were given an opportunity to participate the discount store's CSR activity program. We performed field survey and collected data of 146 respondents. We analyzed the data using PASW statistics 21.0 and AMOS 16.0 in order to test our structural model. Results - The results showed that consumers who participated more in initiating corporate social responsibility revealed higher score for corporate ability associations and corporate social responsibility associations. These corporate associations had a positive effect on customer satisfaction, which leads to higher attitude toward revisit intentions. Specifically, hypothesis 1.1 "As Customer participation in CSR process increases, the evaluation of CA associations will be positive,"was supported. Hypothesis 1.2 "As Customer participation in CSR process increases, the evaluation of CSR associations will be positive," was supported. Hypothesis 2.1 "As the evaluation of CA associations is positive, satisfaction with the firm will increase," was supported. Hypothesis 2.1 "As the evaluation of CSR associations is positive, satisfaction with the firm will increase," was supported. Hypothesis 3 "As satisfaction with the firm increases, revisit intentions with the firm will increase," was supported. Conclusions - This research is the first to study the relationship between customer participation in CSR process, CSR, and consumer reactions. This research also contributes to customer participation and corporate social responsibility literature by suggesting customer participation as an antecedent and empirically demonstrating the positive relationships between the constructs. The findings of this research may offer managerial implications for marketing practitioners. When performing corporate social initiatives, it is better to let the customer participate in the process which leads to higher corporate ability associations and corporate social responsibility associations, also higher satisfaction and revisit intentions. Our results provide useful information to practioners that spontaneous participation of consumers makes CSR initiatives effective and successful. Limitations and ideas for further research remain in this research. For example, our focus on the logic was cognitive evaluations(e.g. corporate associations) but affective dimensions might be considered since recent researches are investigating the relationship between customer participation and affective reaction as a response. Despite the limitations, this research have unique and applicable implications for academics and practitioners.
