  • Purpose: This study aimed to identify influencing factors on the stress of employees in large corporations by examining relationships between self-esteem, emotional intelligence, and mindfulness. Methods: A hundred and sixty four employees from large corporations completed self-reporting questionnaires during November and December, 2019. The collected data were analyzed with SPSS/WIN 22.0 using descriptive statistics, the t-test, ANOVA, correlation, and multiple regression analysis. Results: The scores were 2.96±0.40 for "self-esteem", 3.56±0.61 for "emotional intelligence", 4.01±0.04 for "mindfulness", and 2.21±0.79 for "stress response". A regression analysis identifying factors affecting the stress response of employees in large corporations showed that "mindfulness" was the most significant factor (β=-.58, p<.001), followed by "emotional intelligence" (β=-.21, p=.005) and "self-esteem" (β=-.16, p=.009). The explanatory power of these variables for the stress response of employees in large corporations was 48%. Conclusion: Our findings suggest that self-esteem, emotional intelligence, and mindfulness are significantly related to employees' stress response in large corporations. Therefore, stress response management programs should be developed to improve self-esteem, emotional intelligence, and mindfulness.

  • Adverse environmental conditions such as drought, high salt and cold/freezing are major factors that reduces crop productivity worldwide. According to a survey, $50-80\%$ of the maximum potential yield is lost by these 'environmental or abiotic stresses', which is approximately ten times higher than the loss by biotic stresses. Thus, Improving stress-tolerance of crop plants is an important way to improve agricultural productivity. In order to develop such stress-tolerant crop plants, we set out to identify key stress signaling components that can be used to develop commercially viable crop varieties with enhanced stress tolerance. Our primary focus so far has been on the identification of transcription factors that regulate stress responsive gene expression, especially those involved in ABA-mediated stress response. Be sessile, plants have the unique capability to adapt themselves to the abiotic stresses. This adaptive capability is largely dependent on the plant hormone abscisic acid (ABA), whose level increases under various stress conditions, triggering adaptive response. Central to the response is ABA-regulated gene expression, which ultimately leads to physiological changes at the whole plant level. Thus, once identified, it would be possible to enhance stress tolerance of crop plants by manipulating the expression of the factors that mediate ABA-dependent stress response. Here, we present our work on the isolation and functional characterization of the transcription factors.

  • Purpose: The purpose of this study was to observe the effects of biofeedback training on the perceived stress, stress response, and academic resilience of nursing students. Methods: The research used a randomly assigned control group pretest-posttest design. The study participants were 34 senior students from the College of Nursing of S University. The study was conducted from March to April 2012. The biofeedback training conducted in this study consisted of eight sessions, each divided into two stages: 15 minutes each for breathing biofeedback training and electromyography (EMG) biofeedback training. The collected data were analyzed using SPSS version 19.0. Results: We found statistically significant decreases in perceived stress and EMG levels and an increase in academic resilience in the experimental group. Conclusion: The results showed that the biofeedback training for the nursing students was extremely effective in reducing their levels of perceived stress and EMG while increasing academic resilience. To clarify the effects of biofeedback training on the biological stress response, participants with a higher level of stress response should be recruited in future studies.

  • A diverse range of stresses such as heat, cold, salt, ethanol, oxygen starvation or nutrient starvation induces same stress-responsive proteins. This general stress response enhances bacterial survival significantly. In Bacillus subtilis and closely related Gram-positive bacteria Listeria monocytogenes, the general stress response is controlled by the alternative transcription factor ${\sigma}^B$. The activity of ${\sigma}^B$ is regulated post-translationally by a signal transduction network that has been extensively studied in B. subtilis, and serve as a model for L. monocytogenes. The proposed model of L. monocytogenes signal transduction network is similar to that of B. subtilis, but the energy stress pathway is missing. More than 150 general stress proteins belong to ${\sigma}^B$ regulon of B. subtilis and L. monocytogenes. In both bacteria, ${\sigma}^B$ function is primarily important for resistance to diverse stresses. In addition, ${\sigma}^B$ function contributes to the control of important virulence genes in food-borne pathogen L. monocytogenes. Therefore, understanding of the general stress response is important not only for bacterial physiology, but also for pathogenicity.

  • This study analyzed the correlation between sensory processing types and stress responses in university students. A survey was conducted on 99 university students in Gyeonggi-do and Chungcheong-do. The survey contents consisted of Adolescent/Adult Sensory Profile and Stress Response Inventory. Data were analyzed using SPSS version 21.0 for descriptive statistics and Pearson correlation. As a result of the study, low-registration and sensory sensitivity were all correlated except for aggression of stress response, and sensory avoiding was all correlated of stress response. Sensory seeking was net related to any domain of stress response. Based on the results of this study, taking into account the correlation between sensory processing types and stress responses, it is recommended for convergence with other treatments to develop self-regulation strategies for coping with stress in university students.

  • The Golgi apparatus modifies and transports secretory and membrane proteins. In some instances, the production of secretory and membrane proteins exceeds the capacity of the Golgi apparatus, including vesicle trafficking and the post-translational modification of macromolecules. These proteins are not modified or delivered appropriately due to the insufficiency in the Golgi function. These conditions disturb Golgi homeostasis and induce a cellular condition known as Golgi stress, causing cells to activate the 'Golgi stress response,' which is a homeostatic process to increase the capacity of the Golgi based on cellular requirements. Since the Golgi functions are diverse, several response pathways involving TFE3, HSP47, CREB3, proteoglycan, mucin, MAPK/ETS, and PERK regulate the capacity of each Golgi function separately. Understanding the Golgi stress response is crucial for revealing the mechanisms underlying Golgi dynamics and its effect on human health because many signaling molecules are related to diseases, ranging from viral infections to fatal neurodegenerative diseases. Therefore, it is valuable to summarize and investigate the mechanisms underlying Golgi stress response in disease pathogenesis, as they may contribute to developing novel therapeutic strategies. In this review, we investigate the perturbations and stress signaling of the Golgi, as well as the therapeutic potentials of new strategies for treating Golgi stress-associated diseases.

  • Aim of the study: Thermal stress is a central determinant of osseous surgical outcomes. Interestingly, the temperatures measured during endosseous surgeries coincide with the temperatures that elicit the heat shock response of mammalian cells. The heat shock response is a coordinated biochemical response that helps to protect cells from stresses of various forms. Several protective proteins, termed heat shock proteins (hsp) are produced as part of this response. To begin to understand the role of the stress response of osteoblasts during surgical manipulation of bone, the heat shock protein response was evaluated in osteoblastic cells. Materials & methods: With primary cell culture studies and ROS 17/2.8 osteoblastic cells transfected with hsp27 encoding vectors culture studies, the thermal stress response of mammalian osteoblastic cells was evaluated by immunohistochemistry and western blot analysis. Results: Immunocytochemistry indicated that hsp27 was present in unstressed osteoblastic cells, but not fibroblastic cells. Primarily cultured osteoblasts and fibroblasts expressed the major hsp in response to thermal stress, however, the small Mr hsp, hsp27 was shown to be a constitutive product only in osteoblasts. Creation of stable transformed osteoblastic cells expressing abundant hsp27 protein was used to demonstrate that hsp27 confers stress resistance to osteoblastic cells. Conclusions: The demonstrable presence and function of hsp27 in cultured bones and cells implicates this protein as a determinant of osteoblastic cell fate in vivo.

  • The purpose of this study was to determine the mediating effects of stress associated with university life and the stress response of university students' resilience towards the negative emotions of health department students. As a research method, 284 students in the health department of Gyeongsangnamdo were surveyed. Data were analyzed in terms of frequency, correlation and regression using SPSS 22.0 program. The results of the study were as follows. The mean score of resilience towards negative emotions among students in the health department was 4.49, while stress associated with university life was 2.74. As a result of the correlation analysis among resilience towards negative emotion, stress response and stress associated with university life, the negative emotion was found to have a negative correlation with the stress associated with university life and the stress response. Resilience towards negative emotions was found to reduce the stress associated with university life by mitigating the stress response. Therefore, in this study, resilience appears to affect the stress associated with university life and the students' response to it. Therefore, for students in the health department who are exposed to stress associated with university life, the resilience towards negative emotions may be a way of alleviating the stress response.
