Stress Level of Nursing Students in Completing Final Project

Background. The stress response can be experienced by anyone when something unpleasant, uncomfortable, or disturbing to someone's peace occurs. This is often experienced by some final-year students, who are required to be able to complete their final project (thesis) as a graduation requirement. Conditions felt by students such as feelings of anxiety, worry, lack of enthusiasm, excessive fatigue, feeling left behind by friends who are already at a faster stage, and difficulties in completing the final assignment (thesis) can cause a stress response.
 Aim. This study aim to identify the stress level of nursing students in the preparation of the final project.
 Methods. A cross-sectional study was conducted using the Perceived Stress Scale (PSS-10) questionnaire. Data collection was carried out by filling out a questionnaire that consisted of 2 parts, namely demographic data and the stress level variable experienced by the respondent within the last month. The sample in this study was 131 students who were taking thesis courses. The sampling technique is total sampling.
 Results. The results showed that 23 students were completing their final assignment (thesis) with low stress (17.6%), 106 respondents with moderate stress (80.9%), and 2 respondents with heavy stress (1.5%).
 Conclusion. The majority of students who are completing their final project (thesis) experience moderate stress. This shows that they feel an inconvenience or a burden but must still complete their duties to achieve a bachelor's degree.
 

Gender Differences in the Psychopathology of Mixed Depression in Adolescents with a Major Depressive Episode.

Gender differences have been reported in the severity and psychopathological features of major depressive disorders among adults but are poorly reported in adolescent samples. This study aimed to examine gender differences in the psychopathology of mixed depression among adolescents. We analyzed 341 outpatients with the current major depressive episode (MDE) retrospectively to identify patients with DSM-5 MDE with mixed features. We compared examiner-rated depressive and (hypo)manic symptoms and self- and parent-reported symptoms between sexes. We identified 76 patients with an MDE with mixed features (67.1% females, 32.9% with bipolar disorder). Depression severity was significantly greater in females versus males (CDRS-R total score 56.2 vs. 48.2, p = 0.014). Depressive symptoms were significantly and independently found to be more severe among females in a logistic regression model, including excessive fatigue (OR 1.68; p = 0.025), low self-esteem (OR 1.67; p = 0.04), excessive weeping (OR 1.62; p = 0.021), and CBCL AAA index (OR 1.04; p = 0.015). None of the depressive symptoms scored greater in males. Males had higher levels of motor activity (2.12 vs. 1.69; p = 0.048) and pressured speech (1.80 vs. 1.24; p = 0.004). Self-rated anxiety (69.3 vs. 56.8, p = 0.047) and CBCL AAA index (207 vs. 189; p = 0.007) were higher in females. Adolescent depression with mixed features is more severe in women, with a higher expression of core affective symptoms and excessive fatigue. While in males, slightly higher levels of psychomotor activation are reported, in females, emotional dysregulation and excessive weeping may subtend a difference in a broader spectrum of mixed features.

Acute Effects of Complex Conditioning Activities on Athletic Performance and Achilles Tendon Stiffness in Male Basketball Players.

The goal of this study was to compare the effects of a bilateral conditioning activity consisting of back squats and drop jumps with a unilateral one consisting of split squats and depth jumps to lateral hop over sequentially performed countermovement jump (CMJ), modified t-agility test (MAT), and Achilles tendon stiffness. Twenty-six basketball players participated in this study and were randomly and equally assigned to one of two different test groups: bilateral (B - CA) or unilateral (U - CA) conditioning activity group. The B - CA group completed 2 sets of 4 repetitions of back squats at 80% of one-repetition maximum (1RM), then 10 drop jumps, while the U - CA group performed 2 sets of 2 repetitions of split squats on each leg at 80%1RM, followed by 5 depth jumps to lateral hop on each leg as conditioning activity (CA) complexes. After a warm-up and 5 min before the CA the baseline Achilles tendon stiffness, CMJ, and MAT time measurement were performed. In the 6th min after the CA, all tests were re-tested in the same order. The two-way repeated measures mixed ANOVAs revealed that both B - CA and U - CA failed to produce significant improvements in CMJ and MAT performance. In addition, a significant increase in Achilles stiffness was demonstrated with both protocols (a main effect of time: p = 0.017; effect size = 0.47; medium). This study revealed that combining back squats and drop jumps, as well as split squats and depth jumps to a lateral hop, had no effect on subsequent CMJ and MAT performance in basketball players. Based on these results, it can be assumed that combinations of exercises, even if they have similar movement patterns, may cause excessive fatigue, resulting in no PAPE effect.

Deep venous thrombosis and hyponatremia associated with citalopram use for behavioral symptoms in Parkinson’s disease: a case report

BackgroundEvidence is limited regarding the optimal therapeutic approach for neuropsychiatric symptoms associated with Parkinson’s disease dementia (PDD). Selective serotonin reuptake inhibitors (SSRIs) are widely used for mood disorders and behavioral symptoms in older adults with cognitive impairment, but they have limited efficacy in patients with PDD. The effect of SSRIs on hemostasis is also unclear. This report describes a patient with PDD who developed deep venous thrombosis (DVT) and hyponatremia after initiating citalopram treatment.Case presentationAn 86-year-old woman with PDD presented to our emergency department with altered mental status, generalized weakness, and left lower leg swelling. Citalopram was begun 4 weeks previously for behavioral changes and was discontinued 2 days before presentation because of excessive fatigue. At presentation, her plasma sodium level was 123 mg/dL. Brain computed tomography showed age-related changes. Doppler ultrasound revealed a DVT in the left lower leg. The patient was treated with hypertonic saline and intravenous heparin. After normalization of her sodium, she was discharged on donepezil and apixaban. At follow-up, her sodium remained normal, and her cognition and behavior were noticeably improved.ConclusionOlder adults with Parkinson’s disease are sensitive to adverse effects of psychotropic agents, including SSRIs, which are not recommended first-line agents for behavioral symptoms in PDD. Upon initiating SSRIs in older patients with functional decline and multiple comorbidities, physicians need to evaluate the patient’s risk factors for bleeding or thrombosis. Physical activities should also be maintained as much as possible.

Enhancing Prosthetic Control through High-Fidelity Myoelectric Mapping with Molecular Anchoring Technology.

Myoelectric control utilizes electrical signals generated from the voluntary contraction of remaining muscles in an amputee's stump to operate a prosthesis. Precise and agile control requires low-level myoelectric signals (below 10% of maximum voluntary contraction, MVC) from weak muscle contractions such as phantom finger or wrist movements, but imbalanced calcium concentration in atrophic skin can distort the signals. This is due to poor ionic-electronic coupling between skin and electrode, which often causes excessive muscle contraction, fatigue and discomfort during delicate tasks. To overcome this challenge, a new strategy called molecular anchoring has been developed to drive hydrophobic molecular effectively interact with and embed into stratum corneum for high coupling regions between ionic fluxes and electronic currents. The use of hydrophobic poly(N-vinyl caprolactam) gel has resulted in an interface impedance of 20 kΩ, which is 1/100 of a commercial acrylic-based electrode, allowing the detection of ultralow myoelectric signals (∼1.5% MVC) that approach human limits. With this molecular anchoring technology, amputees operated a prosthesis with greater dexterity, as phantom finger and wrist movements w ere predicted with 97.6% accuracy. This strategy provides the potential for a comfortable human-machine interface when amputees accomplish day-to-day tasks through precise and dexterous myoelectric control.

1022 Two Teenagers with New Onset Insomnia post COVID

Abstract Introduction Sleep disturbances are increasingly seen in COVID-19 infection. Multiple reports have described the onset of insomnia, excessive daytime sleepiness, and fatigue in patients with both acute COVID infection and long COVID syndrome. Most of these are limited to adults. We report the cases of 2 teenagers with new onset chronic insomnia post COVID-19 infection. Report of case(s) The first patient is a 14-year-old male who presented with sleep onset and sleep maintenance insomnia, excessive daytime sleepiness, difficulty concentrating, fatigue, and chronic cough, with onset five months prior presentation to the sleep clinic. He developed these symptoms after testing positive for COVID-19. He had significant impairment with multiple school absences and tardies for which he required accommodation. He completed a 2-week actigraphy test which showed prolonged sleep latencies and insufficient sleep. He was scheduled for polysomnography (PSG) followed by a multiple sleep latency test (MSLT) but could not proceed to MSLT due to insufficient sleep the night before. The PSG did not reveal either obstructive sleep apnea or periodic limb movements of sleep. His laboratory testing was significant for a low ferritin level of 21. He was referred for IV iron infusion due to intolerance for oral iron. He was started on melatonin without benefit. He was offered clonidine and trazodone but declined. The second patient, a 17-year-old male, presented with insomnia of 3 months duration which started after an acute COVID infection. In addition to insomnia, he had comorbid mood symptoms. He went from being engaged in school and work to being unmotivated and listless. His actigraphy testing revealed he was having sufficient sleep on several days during which he reported not getting any sleep. He failed trials of multiple medications including melatonin, trazodone, hydroxyzine, and gabapentin. He also denied benefit with CBT-I. Conclusion These case reports link COVID 19 and chronic insomnia in pediatric patients. While it is yet unclear whether the development of sleep disturbances post COVID is as a result of an intrinsic characteristic of the COVID-19 virus or the biopsychosocial effects of the pandemic, it is important to develop and implement targeted interventions focused on recognizing and treating insomnia early.

Treatment of depression with a combination of mirtazapine and venlafaxine - a literature review

Clinical depression is a psychiatric disorder characterized by symptoms such as loss of interest and pleasure from typically enjoyable activities (anhedonia), pervasive low mood, and diminished energy leading to excessive fatigue and lower activity which have been present in a patient for at least two weeks. Available therapies consist primarily of pharmacological intervention. Indeed, some groups of medications such as SSRIs, SNRIs, TCA’s and tetracyclic antidepressants have been used to treat depression for decades, frequently in combinations. An example of such a combination is “California Rocket Fuel” composed of venlafaxine and mirtazapine Objective: To review the current literature on the efficacy of the combination of venlafaxine and mirtazapine in treating clinical depression both in drug-resistant depression and as a first-line option. To explore the risks and benefits of this choice of therapy and discuss its potential mechanism of action. Methods: Literature review of Pubmed, Google Scholar, Science Direct, and available medical textbooks. Conclusions: Treatment with venlafaxine and mirtazapine is safe, especially for drug-resistant depression. It is worth considering adding venlafaxine to already ongoing pharmacotherapy with mirtazapine when the patient experiences sleepiness and the symptoms of depression have not been sufficiently reduced. Augmenting venlafaxine treatment with mirtazapine also seems necessary when the patient complains of insomnia. One may consider implementing such therapy as a first-line treatment in patients who suffer from depression for a long time and experience insomnia in its course.

A Theoretical Training Plan and Facility for Ontario-Based Olympic Weightlifters

Olympic Weightlifting is a sport where athletes of different weight classes utilize either the Snatch or Clean and Jerk (CJ) technique to lift the heaviest load overhead. This case study describes the training program for a team of Senior (age; 18-35 years) Olympic weightlifters during a normal competitive season. The team of Olympic weightlifters will be participating in team training 3 to 4 times a week; however, variations will occur on the training schedule for each individual athlete based on the on-going testing results. Each athlete will also participate in an additional day of training noted as the “active rest” day which prioritizes injury management for the individual based on their test results, during the training season. In conclusion, the training program in this study provided an insight on implementing velocity profiling into an Olympic weightlifting training program. The device in this study (PUSH Band) quantifies the bar movement via the force velocity curve and the coach has a clearer means in which to determine the repetitions that follow. This study is based around the theoretical idea of implementing a means in which to avoid the traditional periodization rep schema to administer training volume, but rather utilize new technologies. To conclude, methods that accommodate for velocity profiles to determine volume in conjunction with 1RM percentages and a coach’s discretion may allow for more efficient training and a reduction in excess fatigue.

Development and Implementation of Prioritized Care in a Tertiary Hospital Intensive Care Unit During the Sars-Cov-2 Pandemic

Introduction:In the event of a major event or disaster, the intensive care unit (ICU) should be able to offer an adapted and proportional response, within a limited time frame, to the influx of patients who can benefit from the technical facilities of the University Hospitals of Geneva. We developed an innovative approach to ICU care aimed to guarantee continuity by protecting healthcare staff from excessive fatigue and by tailoring the care provided from individualized care to the best care for the most people.Method:A modified organizational and systematic investigation method (MINOS, Paries - 2013) was used to elaborate an ICU security model; threats to activity shut down were identified and their prevention, recovery, and mitigation were planned. These actions were updated following the evolution of the crisis. Crew resources management (CRM) and bedside simulations were used in the implementation phase.Results:The ICU security model pillars were staff protection and patient management; the identified threats to activity continuity were lack of human resources, activity overload, medical errors, pressure sores and healthcare acquired infections; they were evaluated at intermediate or high risk to patients’ safety. The prioritized care plan was developed to control, recover, and mitigate these threats. It consisted in: adaptable level of ICU care, modular organization by cell, huddles, matrix for activities prioritization and controlled delegation method. Before implementation, 55 nurses and 46 doctors were trained by CRM courses and simulations. The pilot phase was deployed in one cell, from December 2021 to January 2022; 67 patients were admitted in the period; 13 adaptations to the original plan were introduced. No critical safety issues were reported.Conclusion:The prioritized care could be an adapted and proportional ICU response to a major event allowing the continuity of the activity while protecting staff from overload. Further tests are needed.

0973 HGNS Sensing Lead Damage After 3D Mammogram Requiring HGNS IPG and Lead Re-Implantation

Abstract Introduction Obstructive sleep apnea (OSA) is associated with excessive daytime sleepiness, nocturnal hypoxemia, and daytime fatigue. Standard therapy is with positive airway pressure (PAP) therapy. If this is unsuccessful or poorly tolerated, a hypoglossal nerve stimulator (HGNS) can be surgically implanted for treatment. The goal of HGNS treatment is to advance the tongue with each respiration during sleep to relieve oropharyngeal obstruction causing OSA. This therapy has been shown to be efficacious and well tolerated for moderate to severe sleep apnea with a low complication rate. Report of case(s) A 61 year-old female with history of obesity and severe OSA presented to the sleep clinic with complaint of excessive daytime sleepiness and persistently elevated apnea-hypopnea index (AHI) of 42 events/hour despite adequate usage of CPAP therapy. She underwent an HGNS placement for treatment. Following HGNS activation she used it nightly and three months after implantation underwent an HGNS titration study which was successful (AHI 5.7) and the patient was started on optimal treatment settings with resulting resolution of OSA symptoms. After a period of successful device usage, she presented for follow up and reported complaints of excessive fatigue and sleepiness that was sudden. She attributed these changes to a 3D mammography study she underwent for breast cancer surveillance. Repeat home sleep apnea testing showed sudden worsening of her AHI to 50.6. During a thorough investigation of her device, HGNS sensing waveforms indicated possible sensing lead fracture. The patient was taken to the operating room for implanted pulse generator removal and replacement with new sensing and stimulation leads. Intra-operatively, it was noted that the distal sensing lead had several tears of the polyurethane insulation near the hub of the sensor. Following successful re-implantation sensing returned to normal and she has continued HGNS treatment. Conclusion We present a case of an unusual complication of HGNS sensing lead damage following a 3D mammography study. This led to surgical exploration with removal of a torn sensing lead and re-implantation of the HGNS generator and leads. Attention should be brought to patients and providers in the future regarding this rare, but potentially serious complication. Support (if any)

Research on Symptoms, Treatment and Prevention of Lumbar Muscle Strain

The rapid development of the medical industry has eased the health worries of many people. For example, uterine cancer and breast cancer are no longer as incurable as they used to be. Benign tumors basically do no harm to people's health. However, diseases such as lumbar muscle strain have not received much attention in today's medical field. Lumbar muscle strain is an injury caused by excessive fatigue. When the lumbar muscles are overused or overloaded, there will be ischemia, spasm, tension, pain, swelling and other inflammatory manifestations. That is, we feel "low back pain." This kind of illness cannot be improved very well by going to the hospital for surgery. Through this paper, we will introduce what lumbar muscle strain is, what its clinical manifestations are, and what solutions are available for different groups of people. The experimental conclusion of this paper is that there is still a lot of room for development in the field of treating lumbar muscle strain. At present, physiotherapy is the method to solve the least side effects of lumbar muscle fatigue, and the effect is relatively obvious. However, the way to avoid the disease is to pay attention to your posture, control your weight, and eat a healthy diet.

Associations between excessive fatigue and pain, sleep, mental-health and work factors in Norwegian nurses.

To investigate whether pain, sleep duration, insomnia, sleepiness, work-related factors, anxiety, and depression associate with excessive fatigue in nurses. Fatigue among nurses is a problem in the context of ongoing nursing shortages. While myriad factors are associated with fatigue not all relationships are understood. Prior studies have not examined excessive fatigue in the context of pain, sleep, mental health, and work factors in a working population to determine if associations between excessive fatigue and each of these factors remain when adjusting for each other. A cross-sectional questionnaire study among 1,335 Norwegian nurses. The questionnaire included measures for fatigue (Chalder Fatigue Questionnaire, score ≥4 categorized as excessive fatigue), pain, sleep duration, insomnia (Bergen Insomnia Scale), daytime sleepiness (Epworth Sleepiness Scale), anxiety and depression (Hospital Anxiety and Depression Scale), and work-related factors. Associations between the exposure variables and excessive fatigue were analyzed using chi-square tests and logistic regression analyses. In the fully adjusted model, significant associations were found between excessive fatigue and pain severity scores for arms/wrists/hands (adjusted OR (aOR) = 1.09, CI = 1.02-1.17), hips/legs/knees/feet (aOR = 1.11, CI = 1.05-1.18), and headaches/migraines (aOR = 1.16, CI = 1.07-1.27), sleep duration of <6 hours (aOR = 2.02, CI = 1.08-3.77), and total symptom scores for insomnia (aOR = 1.05, CI = 1.03-1.08), sleepiness (aOR = 1.11, CI = 1.06-1.17), anxiety (aOR = 1.09, CI = 1.03-1.16), and depression (aOR = 1.24, CI = 1.16-1.33). The musculoskeletal complaint-severity index score (aOR = 1.27, CI = 1.13-1.42) was associated with excessive fatigue in a separate model adjusted for all variables and demographics. Excessive fatigue was also associated with shift work disorder (OR = 2.25, CI = 1.76-2.89) in a model adjusted for demographics. We found no associations with shift work, number of night shifts and number of quick returns (<11 hours between shifts) in the fully adjusted model. Excessive fatigue was associated with pain, sleep- and mental health-factors in a fully adjusted model.

Research on fatigue identification methods based on low-load wearable ECG monitoring devices

The identification of fatigue in personal workers in particular environments can be achieved through early warning techniques. In order to prevent excessive fatigue of medical workers staying in infected areas in the early phase of the coronavirus disease pandemic, a system of low-load wearable electrocardiogram (ECG) devices was used as intelligent acquisition terminals to perform a continuous measurement ECG collection. While machine learning (ML) algorithms and heart rate variability (HRV) offer the promise of fatigue detection for many, there is a demand for ever-increasing reliability in this area, especially in real-life activities. This study proposes a random forest-based classification ML model to identify the four categories of fatigue levels in frontline medical workers using HRV. Based on the wavelet transform in ECG signal processing, stationary wavelet transform was applied to eliminate the main perturbation of ECG in the motion state. Feature selection was performed using ReliefF weighting analysis in combination with redundancy analysis to optimize modeling accuracy. The experimental results of the overall fatigue identification achieved an accuracy of 97.9% with an AUC value of 0.99. With the four-category identification model, the accuracy is 85.6%. These results proved that fatigue analysis based on low-load wearable ECG monitoring at low exertion can accurately determine the level of fatigue of caregivers and provide further ideas for researchers working on fatigue identification in special environments.

Analysis of the Physical Conditions of Men's Futsal Athletes at the Kenanga Futsal Club in Bengkulu City

Achievement sports are sports that foster and develop athletes in a planned, tiered and sustainable manner through competence to achieve high achievements with the support of sports science and technology. In accordance with the definition of achievement sport mentioned above, achievement sport is a sport of fostering and developing potential in a person which is carried out in a planned, tiered and competent manner with the aim of achieving high achievements.&#x0D; In carrying out sports activities a person must have a good physical condition so that he is able to carry out the sports activities he does without experiencing excessive fatigue, conversely if a person has a poor physical condition let alone bad then a person will have difficulty in carrying out these sports activities causing excessive fatigue. Achievement sports that are developing at this time range from individual sports to group sports or team sports.&#x0D; Through this futsal sport, teenagers get many benefits, especially in terms of good physical, mental and social growth. The purpose of people playing futsal is basically the same, namely to have fun, get physical fitness and to achieve optimal performance.&#x0D; This research is a descriptive type of research, which aims to find out the problems that occur in the men's Futsal athletes at the Bengkulu Kenanga Club, how the level of physical condition of futsal athletes decreases.&#x0D; Based on the results of the research above, it can be concluded that during training, many athletes are lazy. Because during practice the athletes feel they are too portioned during practice. Even though the purpose of physical exercise is to build strength, agility and balance. And there are also many factors that make the physical condition of male futsal athletes decline, including the effects of smoking, frequent staying up late, lack of regular exercise, these are some of the things that make athletes very weak.

Epidemiology of COVID-19 in two cities in southern Brazil: a cross-sectional population-based study

The first recommendations to prevent coronavirus disease 2019 (COVID-19) were made without epidemiological information on what would be people’s behaviors in view of the biopsychosocial and physical effects of confinement because of a health emergency with great economic impact. Objective: To determine the incidence of COVID-19; analyze the associated behavioral and sociodemographic factors. Methods: Cross-sectional population-based study with a representative sample of two cities in southern Brazil. 2,170 individuals aged 18 years or over were interviewed from October 2020 to January 2021. Data were collected in person at the place of residence of the individuals using a questionnaire. Results: The incidence of COVID-19 was 6.8% (95% confidence interval, CI: 5.4; 8.4), and was significantly higher in white people, aged between 18 and 59 years, married, with higher education, higher family income, and who lived in an apartment. The incidence of COVID-19 was associated with diabetes. People who stayed less time at home has a higher incidence (3.7% versus 7.5%). The most reported symptoms were excessive tiredness, reduced smell and taste. Most of the individuals (85%) sought a health facility and less than 5% were hospitalized. Conclusion: Almost one in ten individuals was infected by COVID-19. The incidence was higher for adults (because of being more exposed), individuals from higher socioeconomic level (because of having tested more) and in diabetics. Almost everyone stayed home after being diagnosed with the virus, and the main risk factor was having contact with someone infected.

Specialized palliative care for hospitalized patients with SARS-CoV-2 infection: an analysis of the LEOSS registry

PurposeSymptom control for patients who were severely ill or dying from COVID-19 was paramount while resources were strained and infection control measures were in place. We aimed to describe the characteristics of SARS-CoV-2 infected patients who received specialized palliative care (SPC) and the type of SPC provided in a larger cohort.MethodsFrom the multi-centre cohort study Lean European Open Survey on SARS-CoV-2 infected patients (LEOSS), data of patients hospitalized with SARS-CoV-2 infection documented between July 2020 and October 2021 were analysed.Results273/7292 patients (3.7%) received SPC. Those receiving SPC were older and suffered more often from comorbidities, but 59% presented with an estimated life expectancy > 1 year. Main symptoms were dyspnoea, delirium, and excessive tiredness. 224/273 patients (82%) died during the hospital stay compared to 789/7019 (11%) without SPC. Symptom control was provided most common (223/273; 95%), followed by family and psychological support (50% resp. 43%). Personal contact with friends or relatives before or during the dying phase was more often documented in patients receiving SPC compared to patients without SPC (52% vs. 30%).ConclusionIn 3.7% of SARS-CoV-2 infected hospitalized patients, the burden of the acute infection triggered palliative care involvement. Besides complex symptom management, SPC professionals also focused on psychosocial and family issues and aimed to enable personal contacts of dying patients with their family. The data underpin the need for further involvement of SPC in SARS-CoV-2 infected patients but also in other severe chronic infectious diseases.

PECULIARITIES OF SELF-ATTITUDE OF EDUCATIONISTS WITH DIFFERENT LEVELS OF EMOTIONAL BURNOUT

The article presents the results of an empirical study of the problem of emotional burnout of pedagogues. In particular, an analysis of the peculiarities of self-attitude of educationists with different levels of emotional burnout is made. &#x0D; The nature of the connection between the level of emotional burnout of educationists and the peculiarities of their professional self-consciousness, in particular self-attitude as one of the components of a specialist’s self-consciousness, is analyzed. The results of the comparative study proved that inspite rather high indicators of self-approval and positive self-esteem, the studied pedagogues are not sure that their personality is interesting for others, and they are also convinced that other people and colleagues are not interested in them. We came to the conclusion that most of the symptoms and phases of emotional burnout are not formed within the group of the studied educationists, but they are characterized with a certain emotional closedness, aloofness and indifference, which can be an indicator of their emotional exhaustion, and against this background any emotional involvement into professional affairs and communications can cause the feeling of excessive fatigue of pedagogues.&#x0D; The results of a comparative analysis of peculiarities of the self-attitude of educationists with different levels of emotional burnout indicate a general high level of self-attitude of the subjects, but do not exclude the formation of professional deformations of them. In general, it was found that a high level of positive self-attitude of educationists correlates with a low level of manifestation of symptoms and phases of burnout in their professional activities. Educationists with a positive self-attitude are less likely to feel emotional exhaustion, fatigue, and desolation caused by professional activity. In addition, pedagogues with positive self-attitude are less likely to experience the leveling of professional achievements, disruption of professional communications, dissatisfaction with themselves as professionals and their own professional activity, as well as psychosomatic diseases, perception of the conditions of professional activity and interpersonal relationships in the professional area as psychologically traumatic.

Effect of cryogenic machining-strengthening process on enhanced surface integrity and fatigue properties of ZK61M magnesium alloy

Excessive heat and fatigue are important factors affecting the machinability and service performance of magnesium alloy. Cryogenic processing is an effective method to reduce the temperature of the tool and the component, thus improving the machinability of magnesium alloys. The fatigue of workpieces is affected by machining and strengthening processes. However, the current studies on cryogenic processing hardly comprehensively consider the effect of cutting and rolling. To investigate the effect of cryogenic air and pre-cutting processes on rolling, the sequential cutting and rolling experiments were conducted on ZK61M magnesium alloy under dry and two cryogenic cooling conditions. Effects of coolant during sequential machining and rolling processes on forces, surface roughness, microstructure, hardness and residual stresses were investigated. The fatigue properties of ZK61M in the cryogenic processes were also studied. The results show that the rolling force is affected by the coolant lubrication and the surface hardening generated by the previous process. Cryogenic rolling can effectively reduce the surface roughness, increase the circumferential residual compressive stress and reduce the axial residual compressive stress. The feed force of the dry turning followed by rolling with liquid nitrogen (ST + NR) process is the smallest, which is 136.4 N. And the surface roughness (Ra) is also the smallest, which is 0.42 μm, 46.8 % lower than the traditional process. Meanwhile, the ST + NR process can prolong the fatigue life of ZK61M magnesium alloy by 62.9 % compared with conventional process. Moreover, the surface roughness and residual stress have significant influences on fatigue life of ZK61M magnesium alloy, followed by the depth of work hardening layer, and finally the surface hardness. Cryogenic cutting and strengthening process can effectively suppress the initiation and propagation of fatigue cracks.

Assessment of Sleep Quality among Medical Students During the Covid-19 Pandemic

Objective: To assess the sleep quality among medical students, comparing their sleep cycles during physical and online studies along with other factors associated with sleep patterns. Study Design: Cross-sectional Questionnaire based survey Place and Duration of Study: Department of Community Medicine, HITEC Institute of Medical Sciences Taxila from 1st January 2020 to 31st March 2020 Methodology: One hundred and forty seven students were surveyed in a time period of 1 month. The questionnaire included PSQI Pittsburgh Sleep Quality Index and other clinically validated questions. Students with known sleeping disorders were excluded from this survey. Results: There were 81 (55.1%) females and 65 (44.2%) males with mean age 20±1.4 years. Out of these 94(63.9%) were classified as “Poor Sleepers” and only 53 (36.1%) were “Good Sleepers”. Poor sleep quality was associated with female gender (p&lt;0.05), day-scholar residence status (p&lt;0.054), excessive time required to sleep (p&lt;0.00), excessive screen time usage (p&lt;0.007), increased hours of study (p&lt;0.089), experiencing trouble while driving, eating and socializing (p&lt;0.002), lack of enthusiasm (p&lt;0.000), unsatisfactory daily activities (p&lt;0.000) and poor daytime alertness levels (p&lt;0.360). 104 (70.7%) were aware of the effects of melatonin on sleep, only 51 (34.7%) admitted to have used coffee to stay awake at night. 98 (66.7%) subjects were pre-exam workers, 95 (64.6%) admitted not being able to wake up easily in the morning. Conclusion: The students and hostelites that used less screen time slept better. Excessive daytime tiredness was also a result of poor sleeping habits. Students who studied for longer periods of time and had difficulty waking up in the morning slept poorly. Poor sleepers also find it difficult to interact and are often unambitious about performing their daily menial tasks, as well as displeased with their daily activities. As a matter of fact, we deduce that sleep quality has unanticipated consequences for medical students' social and mental health.
