Abstract:
The diathesis-stress component hypothesis and the mediational role of hopelessness proposed by the hopelessness theory of depression were tested using data from a 16-week longitudinal study of Chinese university undergraduates. Participants (N = 240) completed self-report measures assessing attributional style, negative life events, hopelessness, and hopelessness depression symptoms at 3 time points. The diathesis-stress hypothesis was tested using the latent growth curve model and results showed that as postulated in the hopelessness theory, depressogenic attributional style predicted hopelessness depression following the occurrence of negative life events. Specifically, hopelessness played a partial mediating role in the etiological chain of hopelessness depression.

Abstract:
In recent years, an increasing amount of attention has been devoted to investigating the interpersonal origins of depression and depressive symptoms. Guided by attachment theory and interpersonal models of depression, we describe a diathesis-stress model that has guided our research on how romantic attachment orientations (or styles) are associated with depressive symptomatology. The model presented in this article suggests that when anxious-ambivalent people experience stressful events, they display specific perceptual and behavioral reactions that lead to depressive symptoms. Studies that provide empirical support for parts of the model are discussed. In addition to describing the psychological processes that might exacerbate depressive symptoms in highly ambivalent individuals, the model also identifies novel “pathways” to depression and briefly introduces new theoretical concepts—the constructs of dysfunctional relationship attitudes and relationship deprivation.

Abstract:
AbstractConcurrent and predictive relations among aggression, peer rejection, and self-reported depressive symptoms were examined in 521 third-, fourth-, and fifth-grade children at three time points over 1 year. Increases in aggression were significantly associated with increases in depression, and this relation was mediated, in part, through increases in peer rejection. The relation between peer-reported rejection and depression was mediated by perceived rejection. Finally, we found support for the cognitive diathesis-stress model of depression in children. Controlling for initial levels of depression and peer rejection, the interaction between stress (increases in peer rejection) and a depressogenic attributional style contributed significantly to the prediction of self-reported depressive symptoms 1 year later.

Abstract:
The present study sought to examine a diathesis-stress model involving hope and trauma history as predictors of depressive and anxious symptoms in a sample of 575 college students. Results from regression analyses indicated that hope and trauma were important and unique predictors of both depressive and anxious symptoms in students. Moreover, we found support for a significant Hope×Trauma interaction in predicting both depressive and anxious symptoms. Some implications of the present findings are discussed.

Abstract:
The current study examined the relationship between depression and uncertainty within the stress-diathesis model. Depression is a mental health disorder that is wide spread within our society. However, few causes of this disease have been able to be identified. Studies in uncertainty have shown that it is a major stressor in day-to-day life. Previous research has shown that individuals with high levels of uncertainty show higher levels of depression. The stress-diathesis model, a model originally developed to explain differences in development of schizophrenia, provides a theoretically meaningful way to combine these two concepts. The model states that a person who is likely to develop a disease has an internal mechanism, a diathesis, that will be triggered upon presentation of a stressor. This study tested the idea that uncertainty can be used as a stressor to activate diathesis within an individual, aiding in the prediction of depression. In total, 163 participants were randomly assigned one of three conditions, an uncertainty threat, an affirmation condition, and a control condition. Participants were given pre and post independent variable measures of depression and anxiety. Findings suggest that uncertainty activated negative emotions differentially within the participants, resulting in higher levels of negative affects after the uncertainty threat, especially for participants who already scored relatively higher on depression indicators. These results hint at a possible understanding of why depression rates and diagnosis rates of mental health issues rise during economic downturn and other times of strong uncertainty.

Abstract:
Epidemiological studies of depression give important insights into populations at higher risk of depression, but not everyone in certain high-risk circumstances will develop a clinical depression. ‘Models of depression’ highlights some of the most well-known biological, psychological, and social models ranging from the monoamine hypothesis to Beck’s cognitive model, and then discusses attempts to integrate these into a multi-dimensional psycho-bio-social theory. It highlights the interaction between stress and vulnerability factors, and the importance of considering the origins of the vulnerabilities. In reality, there is no one cause and no single pathway to depression and multiple factors increase vulnerability to depression.

Abstract:
Depression and wound healing are bidirectional processes for adults and children consistent with the conception of depression as systemic. This systemic interaction is similar to the “bidirectional impact of mood disorder on risk for development, progression, treatment, and outcomes of medical illness” generally. And, evidence is growing that the bidirectional impact of mood disorder may be true for injuries and for trauma surgery. Animal models have provided some support that treatment of depression may improve wound healing. An established biological model for a mechanism delaying wound healing is increased cortisol secretion secondary to depression and/or stress, and impaired immune response, in addition or together with the other factors such as genetic or epigenetic risk for depression. Cellular models relate both to wound healing and to depression include cytokines, the inflammatory response (Miller et al, 2008), and cellular aging (Telgenhoff and Shroot, 2005) reflected in shorter leukocyte telomere length (LTL) (Verhoeven et al, 2016). Another model of stress impacting wound healing investigated genetic correlates—immediate early gene expression or IEG from the medial prefrontal cortex, and locomotion, in isolation-reared juvenile rats. Levine et al (2008) compared isolation reared to group reared samples, and found that, immediate gene expression in the medial prefrontal cortex (mPFC) was reduced, and behavioral hyperactivity increased, in juvenile rats with 20% burn injuries. Wound healing in the isolation reared rats was significantly impaired. They concluded that these results provide candidates for behavioral biomarkers of isolation rearing during physical injury, i.e. reduced immediate mPFC gene expression and hyperactivity. They suggested that a biomarker such as IEGs might aid in demarcating patients with resilient and adaptive responses to physical illness from those with maladaptive responses

Abstract:
This chapter examines patterns of comorbidity between eating disorders and mood, anxiety, and substance use disorders along with evidence regarding support for different theoretical models that may account for these patterns. Although comorbidity estimates may be inflated by reliance on treatment-seeking samples and double counting of symptoms that overlap between syndromes, evidence supports elevated risk of mood, anxiety, and substance use disorders in anorexia nervosa, bulimia nervosa, and binge eating disorder. Data from family and twin studies support that eating and anxiety disorders may have a shared diathesis, consistent with the common cause model. Data from longitudinal studies suggest that eating disorders may increase vulnerability for developing a substance use disorder, consistent with the predisposition model. In contrast, comorbidity between eating and mood disorders, such as depression, remains poorly understood. Clinical issues regarding comorbidity of depression and eating disorders along with guidelines for clinicians treating patients with comorbid depression and eating disorders are discussed.

Abstract:
Major depression and posttraumatic stress disorder (PTSD) represent heterogeneous combinations of symptoms. Analyses focusing on these distinctive symptom dimensions can play an important role in explicating key diagnostic phenomena such as comorbidity. We review depression and PTSD from the perspective of the quadripartite model, which posits that it is important to consider two quantitative elements when analyzing the properties of symptoms: (a) the magnitude of their general distress component and (b) their level of specificity. Within both disorders, we identified certain symptoms—insomnia and appetite disturbance in the case of depression, dysphoria within PTSD—that both (a) exhibited poor diagnostic specificity and (b) provided little or no incremental information to their respective diagnoses. We therefore argue that deemphasizing these weak and nonspecific indicators and focusing primarily on more specific types of symptoms potentially can improve the diagnosis and assessment of these disorders.

Abstract:
Animal modeling has advanced our understanding of the underlying pathophysiology of human neuropsychiatric disorders and facilitated development of safer, more efficient medications. Similar to humans with depression, rodents exposed to various stress paradigms exhibit aberrant responses to rewarding stimuli, along with hormonal and immunological dysregulation. Development of more complex models, such as social defeat, has led to a firmer grasp of the mechanisms mediating resilience and susceptibility to stress; and adapted versions of social defeat have yielded insights into how emotional stress influences development of mood disorders. This chapter focuses on stress-induced models of mood disorders and outlines how a depression-like phenotype is induced and tested in rodents.

Abstract:
ABSTRACT Background: Geriatric depression is a mental and emotional disorder affecting older adults. Social support is an important factor known to moderate the deleterious effects of stress in elderly. This study aimed to determine factors affecting depression symptom in the elderly using PRECEDE PROCEED model. Subjects and Method: A cross sectional study was conducted in Surakarta, Central Java. A sample of 200 elderly was selected for this study by cluster random sampling. The dependent variable was depression. The independent variables were gender, marital status, residence, education, family support, and peer support. The data were collected by questionnaire and analyzed by a multiple linear regression run on Stata 13. Results: The risk of depression in elderly increased with female (b= 5.53; 95% CI= 3.38 to 7.70; p<0.001), unmarried (b= 4.15; 95% CI=1.36 to 6.95; p= 0.004), and living at nursing home (b= 8.16; 95% CI= 5.26 to 11.06; p<0.001). The risk of depression decreased with high education (b= -5.51; 95% CI= -7.49 to -3.51; p<0.001), strong peer support (b= -2.75; 95% CI= -4.92 to -0.58; p= 0.013), and strong family support (b= -5.02; 95% CI= -7.96 to -2.09; p<0.001). Conclusion: The risk of depression in elderly increases with female, unmarried, and living at nursing home. The risk of depression decreases with high education, strong peer support, and strong family support. Keywords: depression, elderly Correspondence: Zela Tunurrohmin.

Abstract:
Abstract Laizhouwan sag in Bohai Bay basin is a fault basin controlled by extensional fault depression and strike slip pull apart, which is an important oil and gas exploration area in Bohai Bay. Exploration practice shows that the prediction of high quality reservoir is the core problem of exploration in this area. Based on the analysis of drilling, seismic data and structural physical simulation in Laizhouwan depression, this paper analyzes the structural deformation under the stress field of strike slip extensional superposition, and points out the dynamic source controlled sand model in the strike slip extensional superposition area. Firstly, The structural response of "pressure relief settlement, pressure boosting uplift" under the mechanism of strike slip extension stress superposition stress is the root cause of block uplift drop alternation transformation. As a result, the southern slope zone of Laizhouwan depression shows the structural pattern of early uplift and late uplift in the East and early uplift and late uplift in the west, forming a "seesaw" structural evolution pattern. Secondly, the unique paleogeomorphology controls the orderly distribution of sedimentary system in time and space. In the Paleocene, the east uplifted, forming a local provenance system. In the denudation area above the slope break developed fracture weathering shell type reservoirs, and the subsidence area under the slope break developed fan delta deposits; In the early Eocene, the relatively flat platform palaeogeomorphology was developed, which created favorable conditions for the development of mixed sedimentary body of lacustrine carbonate and delta; At the end of Eocene, the West was pressurized and uplifted, the East was released and subsided, and the braided river delta sediments of Western provenance were developed. Under the guidance of this recognition, the hidden dynamic provenance was successfully identified in the study area.

Abstract:
Depression and anxiety are the most prevalent mental disorders, reaching million people worldwide. As they share many characteristics these two disorders can manifest themselves together. In addition, stress is one of the related factors with both depression and anxiety, being relevant in the analysis of these disorders. This paper proposes a model for ubiquitous care of patients with depression, anxiety and stress disorders (DASD) using gamification and biodata, called iAware. A/B tests evaluated with a clinical population the interaction engagement of the patient to the treatment provided by gamification. Based on the patient’s history, the iAware monitors and applies interventions for the patient at the most appropriate time. Six patients used a prototype with a smartband for two weeks to evaluate iAware. Interactions with intervention stages were greater in patients who used iAware gamified. A more detailed analysis is still required. The evaluated patients got more occurrences of anxiety at home. The patients also filled out a survey based on the Technology Acceptance Model (TAM). TAM results show that patients have found the iAware useful in their anxiety treatment routines.

Abstract:
"In our study, we were testing an online burnout prevention programme among Hungarian teachers between 2016-2019, focusing on the background factors of the intervention effect size. Firstly, we conceptualized teacher burnout factors, and after exploratory and confirmatory factor analysis on the incoming sample (N=224), structure equation model has been built up which relate to work-stressors like effort-reward imbalance and over-commitment, burnout factors, perceived stress, general self-efficacy and depression. Secondly, by testing the stress-management intervention on a cumulated sample (N=37) which based on a mini randomized control trial and a quasi-experiment sample data, the intervention effect size has been evaluated, linear regression and structure equation modelling was used to explore the intervention’ predictor and moderator variables. Results of the conceptualization (N=224) show work stressors alone do not lead to burnout factors. Perceived stress is mediator from effort–reward imbalance to burnout factors. General self-efficacy modifies negative impact of perceived stress on personal accomplishment and directly depersonalization. Coping mechanism of depersonalization and personal accomplishment strengthens one-dimensional approach of burnout. Results of the intervention evaluation show that significant high improvement can be achieved related to the emotional exhaustion (N=37 d=0.89, p?.01). For prevention, all kind of stress-management techniques, improving teachers’ perceptions of work success are presumable. In order to reach higher involvement of the participants for further research cultural adaptation is needed."

Abstract:
In this study an axisymmetric model is set up to study the impact of a spherical water droplet with a planar deformable solid surface using the Lagrange-Euler coupling method which is based on a penalty formulation. The diameter and velocity of the droplet are 0.4 mm and 500 m/s respectively, while the solid is a kind of steam turbine blade material. The generated pressure distribution in the droplet and its variation with time, the formation of lateral jet, the deformation and stress distribution in the solid are obtained and investigated. It is shown that the compressibility of the droplet and the solid plays a significant role during the impact. The water-hammer pressure and the maximum contact edge pressure are calculated and in good agreement with the existing theoretical predictions. The calculated contact radius for shock departure is larger than that of the conventional theoretical prediction, which is analyzed and attributable to the radial motion of the liquid in the compressed region. The formation of the high-speed lateral jet is calculated and the time for the observable jetting is much later than that of the shock departure. This delay is discussed and the reason needs more research. The pressure of the contact edge region remains highest even after a considerable time of shock departure and lateral jetting. In the mean time, a saucer-shaped depression is generated in the center of the impact. The stress waves in solid move faster even before shock departure in the liquid. This causes disturbance of the solid surface before the high-speed lateral jetting and provides site for the scouring action of it, and subsequently may cause material damage and erosion.

Abstract:
One of the standard procedures to test the formability of sheet material is the Erichsen cupping test, in which the metal sheet blank is held in its place over a circular space and depressed by a semi-spherical punch. The depth of depression that can be reached is the measure of the formability. In this work the elastoplastic deformation of the sheet is analyzed by multipurpose Finite Element Method software Comsol Multiphysics. The Comsol package is not specifically developed or focused on the analysis of solid mechanical problems with elastoplastic model behavior and contact problems, and still limited literature is available in which sheet forming processes are analyzed with Comsol. In this work, the development and testing of a simulation model in Comsol is reported and comparison is made with results reported with other FEM software. The development and testing is realized in successive steps of increasing complexity. First a uniaxial stretching is simulated in order to evaluate the implementation of the elastoplastic material behavior. Next, the bending of a plate over a straight line is analyzed, adding the contact boundary condition between tool and sheet surface into the model. Finally, the axisymmetric model of the Erichsen cupping test is implemented. It is found that the default Von Mises yield function results in incorrect stresses, and needs to be replaced by a yield function in which the Von Mises stress is calculated based on the Cauchy tensor. The non-linear contact condition is a source of oscillations in the local stresses near the zone where contact is established. The simulation results obtained with the final model are compared with punch forces, stresses and strains obtained in literature, showing an adequate comparison.

Abstract:
ABSTRACT Backgrund: A growing body of evidence suggests that activity of the stress-responsive hypothalamic-pituitary-adrenal axis and its end-product cortisol also may be associated with perinatal emotional well-being. A number of preventive interventions, such as Yoga, targeting psychosocial and physiological risk factors for perinatal depression have utilized mind-body practices, which embody the idea that the mind interacts with the body to influence physical functioning, improve symptoms, and promote health. This study aimed to investigate effectiveness of prenatal yoga in reducing cortisol hormone in pregnancy Subjects and Method: This was a meta-analysis and systematic review. This study collected published articles during 2000 to 2020 from PubMed, Science Direct, Springer, Proquest, and Chocrane electronic databases. The inclusion criteria were full text, randomized controlled trial, and prenatal yoga intervention. The study subjects were pregnant women who received prenatal yoga for 8 to 20 weeks. Outcome was cortisol hormone reduction during pregnancy. The selected articles were analyzed by PRISMA flow chart and RevMan 5.3. Results: 5 articles from America and Asia were met the inclusion criteria. This study had high heterogeneity (I2=88%; p<0.001). Therefore, this study used random effect model (REM). Prenatal yoga reduced cortisol level 0.59 times in pregnancy (Mean Difference= -0.59; 95% CI= 1.18 to 0.01; p= 0.050). Conclusion: Prenatal yoga is effective to reduce cortisol level in pregnant women. Keywords: prenatal yoga, cortisol hormone, pregnant women Correspondence: Shiva Aflahiyah.

Abstract:
Mental health has become a general concern of people nowadays. It is of vital importance to detect and manage mental health issues before they turn into severe problems. Traditional psychological interventions are reliable, but expensive and hysteretic. With the rapid development of social media, people are increasingly sharing their daily lives and interacting with friends online. Via harvesting social media data, we comprehensively study the detection of mental wellness, with two typical mental problems, stress and depression, as specific examples. Initializing with binary user-level detection, we expand our research towards multiple contexts, by considering the trigger and level of mental health problems, and involving different social media platforms of different cultures. We construct several benchmark real-world datasets for analysis and propose a series of multi-modal detection models, whose effectiveness are verified by extensive experiments. We also make in-depth analysis to reveal the underlying online behaviors regarding these mental health issues.

Abstract:
Traumatic brain injury due to blast exposure is quickly becoming the most frequently seen injury in today’s battlefields. Alterations in cognitive function, such as attention, memory, language and problem solving skills appear to occur as a result of blast-induced TBI. Furthermore, behavioral symptoms such as mood changes, depression, anxiety, impulsiveness and emotional outbursts are associated with blast-induced TBI (Okie et al, 2005). Observed overlaps between symptoms of post-traumatic stress disorder (PTSD) and TBI confound the differential diagnosis. Thus, soldiers with blast-induced TBI may be substantially under-diagnosed after exposure to blast waves. Animal models of blast-induced TBI are underdeveloped and there is a vital need for blast exposure biomarkers to help effectively diagnosis blast-induced TBI. In this study, we have investigated the mechanisms that underlie cognitive impairment of blast-induced neurotrauma. We have studied the cascade of neurochemical changes within the hippocampus of blast-exposed animals using 1H-Magnetic Resonance Spectroscopy (1HMRS). Furthermore, we examined changes in TBI protein markers using Western blotting and immunohistochemistry. Results suggest that exposure to blast waves has a significant effect on the hippocampus.
