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.

일부 그람양성세균들은 고온, 저온, 염, 에탄올, 산소와 영양분 고갈과 같은 다양한 스트레스 상태에 노출되면, 일반 스트레스반응(general stress response)에 의해서 일련의 스트레스 단백질군을 발현시켜 외부 스트레스를 극복하고 세균의 생존력을 증가시킨다. 비병원성균인 Bacillus subtilis의 일반 스트레스반응에 관해서는 많은 연구가 이루어져 있으므로 다른 균의 연구모델로 이용이 가능하다. 본 총설에서는 B. subtilis와 병원성균인 Listeria monocytogenes의 일반 스트레스반응의 유사성과 차이점을 B. subtilis를 모델로 하여 비교하였다. 두 균의 일반 스트레스반응은 대체 전사 인자인 ${\sigma}^B$ (alternative transcription factor sigma B)에 의해서 조절되고 신호전달 네트워크 또한 매우 유사하며, ${\sigma}^B$ 의존성 유전자들에 의해 150여 개의 스트레스 단백질들이 발현된다. 그러나 L. monocytogenes는 B. subtilis의 에너지 스트레스 신호 경로를 가지고 있지 않은 점과, 일반 스트레스반응에 의해 병독 유전자들(virulence genes)이 조절되는 것이 가장 큰 차이점이다. 그러므로 L. monocytogenes의 생리 및 병원성 규명을 위해서는 일반 스트레스반응에 관한 이해가 매우 중요하다.

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.

본 연구는 보건계열 대학생의 부정정서 극복력과 대학생활 스트레스, 스트레스 반응 관계에서 매개효과를 검증하고자 시행하였다. 연구의 방법으로는 경상남도 소재의 보건계열 대학생 284명을 대상으로 설문조사를 시행하였다. 자료의 분석은 SPSS 22.0 프로그램을 이용하여 빈도분석, 상관분석, 회귀분석을 실시하였다. 연구 결과는 다음과 같이 나타났다. 보건계열 학생의 부정정서 극복력은 평균 4.49로 나타났으며 대학생활 스트레스는 2.74로 나타났다. 스트레스 반응에 대해서는 공격성 반응이 1.76으로 가장 낮았고, 피로반응이 2.71로 가장 높았다. 부정정서 극복력과 스트레스 반응, 대학생활 스트레스의 관계를 상관분석 한 결과, 부정정서 극복력은 대학생활 스트레스, 스트레스 반응과 부적상관을 이루는 것으로 나타났다. 부정정서 극복력은 스트레스 반응을 완화시키는 과정을 통해 대학생활 스트레스를 해소하는 것으로 나타났으며 스트레스 반응 하위요인에서도 매개효과를 가지는 것으로 나타났다. 따라서 본 연구에서는 극복력은 대학생활 스트레스와 그에 따른 반응에 영향을 미치고 있는 것으로 보인다. 그러므로 보건계열 대학생 중 대학생활 스트레스에 노출되어 있는 학생에게는 부정정서 극복력이 스트레스 반응을 완화시키는 방법이 될 수 있으며, 스트레스 반응의 하위요인에 받는 적절한 스트레스 완화방법이 요구되어 진다.
