  • We investigated the effect of moderate- and high-intensity resistance training on hippocampal neurotrophic factors and peripheral CCL11 levels in high-fat diet (HFD)-induced obese mice. C57/black male mice received a 4 weeks diet of normal (control, CON; n = 9) or a high-fat diet (HF; n = 27) to induce obesity. Thereafter, the HF group was subdivided equally into the HF, HF + moderate-intensity exercise (HFME), and HF + high-intensity exercise (HFHE) groups (n = 9, respectively), and mice were subjected to ladder-climbing exercise for 8 weeks. The hippocampal brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) levels were significantly lower in the HF group than in the CON group (p < 0.05). In addition, in the HFME and HFHE groups were significantly higher than in the HF group (p < 0.05). The peripheral CCL11 levels were significantly higher in the HF group than in the CON group (p < 0.05). In addition, in the HFME and HFHE groups were significantly lower than in the HF group (p < 0.05). However, there was no significant difference according to the exercise intensity among the groups. Collectively, these results suggest that obesity can induce down-regulation of neurotrophic factors and inhibition of neurogenesis. In contrast, regardless of exercise intensity, resistance training may have a positive effect on improving brain function by inducing increased expression of neurotrophic factors.

  • Background: Both the rapid concentric and eccentric contractions during exercise repeatedly impose excessive stress on muscle tissue. The hamstring muscles are very susceptible to injury due to the tensile stress. Various interventions are currently being undertaken to prevent strain injury before exercise. Stretching is the most common method and is known to have a positive effect on flexibility and muscle performance. However, relatively few studies have investigated the potential negative factors of stretching. Objects: The purpose of this study was to examine changes in pain following the different intensity of the stretching and types of physical stress. Methods: The subjects were divided into three groups based on the intensity of stretching: 100% (S100), 75% (S75), and 50% (S50) of the measured force at the point of discomfort in static stretching and 100% (P100), 75% (P75), and 50% (P50) of the maximum voluntary isometric contraction in Proprioceptive Neuromuscular Facilitation (PNF) stretching. The pain individual subjects perceived after stretching was measured via a Visual Analog Scale (VAS) and compared between the groups Results: Despite the decrease in the intensity of static stretching, no decrease in VAS value was observed. In PNF stretching, a significant decrease was observed at P50 compared to P100. S100 was significantly higher than P75 and P50. Conclusion: Previous studies have shown that PNF has a superior or the same effect on flexibility in comparison with static stretching. This effect was maintained even in moderate intensity. PNF stretching performed under moderate rather than high intensive static stretching, which causes pain and discomfort, might be recommended in clinical settings.

  • Many public buildings such as schools, hospitals, etc., where partial infill walls are present in reinforced concrete (RC) structures, have undergone undesirable damage/failure attributed to captive column effect during a moderate to severe earthquake shaking. Often, the situation gets worsened when these RC frames are non-ductile in nature, thus reducing the deformable capability of the frame. Also, in many parts of the Indian subcontinent, it is mandatory to use fly-ash bricks for construction so as to reduce the burden on the disposal of fly-ash produced at thermal power plants. In some scenario, when the non-ductile RC frame, partially infilled by fly-ash bricks, suffers major structural damage, the challenge remains on how to retrofit and restore it. Thus, in this study, two full-scale one-bay, one-story non-ductile RC frame models, namely, bare frame and RC partially infilled frame with fly-ash bricks in 50% of its opening area are considered. In the previous experiments, these models were subjected to slow-cyclic displacement-controlled loading to replicate damage due to a moderate earthquake. Now, in this study these damaged frames were retrofitted and an experimental investigation was performed on the retrofitted specimens to examine the effectiveness of the proposed retrofitting scheme. A hybrid retrofitting technique combining epoxy injection grouting with an innovative and easy-to-implement steel jacketing technique was proposed. This proposed retrofitting method has ensured proper confinement of damaged concrete. The retrofitted models were subjected to the same slow cyclic displacement-controlled loading which was used to damage the frames. The experimental study concluded that the hybrid retrofitting technique was quite effective in enhancing and regaining various seismic performance parameters such as, lateral strength and lateral stiffness of partially fly-ash brick infilled RC frame. Thus, the steel jacketing retrofitting scheme along with the epoxy injection grouting can be relied on for possible repair of the structural members which are damaged due to the captive column effect during the seismic shaking.

  • The corporate logo symbolizes the company's value, goals and vision as a visual symbol representing the company. It serves as a communication tool for companies by conveying different messages depending on design and color. As demands for ESG management have recently increased, companies have begun to implicitly demonstrate values such as environmental protection and corporate transparency through logos. Companies use logos as a strategy to visually emphasize the value they pursue and project the desired image as a signal. In this process, stakeholders who see the logo experience cognitive bias. Therefore, this study seeks to find out that ESG value can be indirectly communicated by the design of corporate logos, which can also affect a company's ESG evaluation. In addition, this study will examine the moderate effect that logos expect to encounter a greater bias effect as the companies actively include ESG-related issues in corporate disclosure data. This study conducted an analysis of 617 KOSPI-listed companies using ESG evaluation data from 2020 to 2022. The analysis confirmed the significant relation of the type of logo and ESG disclosure on ESG evaluation but found partially moderate effect of ESG disclosure.

  • The purpose of this study was to examine the effect of family stress, coping, family resources on psychological distress and the interactions with family solidarity and coping in unemployed female head. The sample was 101 unemployed female heads(without husband) who are living in Seoul. The results of this study showed that family solidarity had significant buffering effect to moderate relationship between family stress and psychological distress. But the effect of coping on psychological distress was not significant. This means that the family solidarity was very important to decrease the psychological distress(somatization, anxiety, depression) of unemployed female head.

  • Recently the wearable technologies market has diversified to the point where even the leading fashion brands have adopted prototypes. For this reason, consumer- and fashion-centric perspectives on the consumption of wearable technologies are needed for a better understanding of the market. The author tests the effect of design aesthetics of a fictitious smartwatch (i.e., the wearable technology) as a key factor of non-functional hedonic consumption on consumer-perceived product value. The results of an online survey of 233 U.S. shoppers indicate a strong, positive effect of design aesthetics on both the perceived utilitarian and hedonic values of wearable technologies. Furthermore, the hypothesized moderation of gender is statistically confirmed in the mechanism of design aesthetics toward perceived utilitarian value, but gender is found to not moderate the effect of design aesthetics for the smartwatch on hedonic value. Male shoppers are found to be more positively influenced by perceived design aesthetics. Theoretical and managerial implications and study limitations are further discussed.

  • This study investigates the effect of depressive vulnerability on the interpersonal problems of university students. We explore the moderating effects of ego-resilience on the relation between depressive vulnerability and interpersonal problems. We selected 380 university students as participants from Daegu and Gyeongsan cities. Collected data was analyzed by descriptive statistics, Pearson's correlation, moderating effect with SPSS 23.0. PROCESS, a SPSS macro program developed by Hayes (2013). The findings are as follows. First, there were significant correlations between non-sociability and dependency, self-criticism, non-self-assertiveness, over-consideration, dominance, personal relations, emotion control, and optimism. Second, ego-resilience was found to moderate the relationship between depressive vulnerability and non-self- assertiveness, over-consideration, and dominance among university students. This study suggests that intervention to address ego-resilience are important to resolve the interpersonal problems of university students.

  • Companies are increasingly performing corporate social responsibility (CSR) as part of their strategic plans, but the effect of CSR activities on short-term financial performance is disputed. Researchers have found ambiguous relationships through mediating factors, but few studies have investigated internal stakeholders in this context and the firm characteristics that moderate these relationships. This study uses a competitive mediating model that examines job satisfaction as a mediator in the relationship between CSR and short-term financial performance for Korean companies. For the analysis, data from 195 companies covering 2014 to 2017 were collected and analyzed via panel regression. The findings indicate that CSR activities had a negative effect on short-term financial performance but a positive effect on job satisfaction; however, the larger the firm, the smaller the positive effect of CSR activities. Moreover, job satisfaction positively affects short-term financial performance, and this relationship is stronger in service firms.
