Haircuts are certainly a necessity for every human being, especially men. Every year, of course, haircut styles always change in popularity, this is what causes barbershops to become fiercely competitive, especially barbershops. Barbershops are better known for having more up-to-date models and styles than barbershops in general. The more competition, the more problems arise, one of which is The Cut Room Barbershop which is rarely empty of visitors, but has difficulties in measuring the level of customer satisfaction and has problems in providing information to potential new customers. Through this activity, The Cut Room Barbershop can assess the level of customer satisfaction and can provide clear information for potential new customers. By providing media to accommodate consumer ratings and providing brief information on The Cut Room barbershop accounts, it is hoped that this can solve problems and expand the information network to get new customers.

The important role of MSMEs is increasingly being felt in the process of national economic development in Indonesia. Branta Tinggi Village is one of the villages in Tlanakan District, Pamekasan Regency which has a large number of MSMEs. However, there are still many MSME owners in Branta Tinggi Village who do not understand the importance of business legality in the form of making a Business Identification Number (NIB), because some people have an understanding that obtaining business permits and legality is a complicated and time-consuming matter. Meanwhile, the Business Identification Number (NIB) itself plays an important role in running a business. In carrying out this community service activity, the University of Madura KKN 4 Team is trying to increase the potential of MSMEs to improve the welfare of the people of Branta Tinggi Village. One of them is by helping to make NIB (Business Identification Number) in 3 hamlets. This community service activity is given in making a Business Identification Number (NIB) which is carried out through the door to door method where this service activity is carried out in real time by visiting the residence of each UMKM in three hamlets in the village of Branta Tinggi.

Binary stars are ubiquitous; the majority of solar-type stars exist in binaries. Exoplanet occurrence rate is suppressed in binaries, but some multiples do still host planets. Binaries cause observational biases in planet parameters, with undetected multiplicity causing transiting planets to appear smaller than they truly are. We have analyzed the properties of a sample of 119 planet-host binary stars from the Kepler mission to study the underlying population of planets in binaries that fall in and around the radius valley, which is a demographic feature in period–radius space that marks the transition from predominantly rocky to predominantly gaseous planets. We found no statistically significant evidence for a radius gap for our sample of 122 planets in binaries when assuming that the primary stars are the planet hosts, with a low probability (p < 0.05) of the binary planet sample radius distribution being consistent with the single-star population of small planets via an Anderson–Darling test. These results reveal demographic differences in the planet size distribution between planets in binary and single stars for the first time, showing that stellar multiplicity may fundamentally alter the planet formation process. A larger sample and further assessment of circumprimary versus circumsecondary transits is needed to either validate this nondetection or explore other scenarios, such as a radius gap with a location that is dependent on binary separation.

We present a comprehensive analysis of the evolution of the morphological and structural properties of a large sample of galaxies at z = 3–9 using early James Webb Space Telescope (JWST) CEERS NIRCam observations. Our sample consists of 850 galaxies at z > 3 detected in both Hubble Space Telescope (HST)/WFC3 and CEERS JWST/NIRCam images, enabling a comparison of HST and JWST morphologies. We conduct a set of visual classifications, with each galaxy in the sample classified three times. We also measure quantitative morphologies across all NIRCam filters. We find that galaxies at z > 3 have a wide diversity of morphologies. Galaxies with disks make up 60% of galaxies at z = 3, and this fraction drops to ∼30% at z = 6–9, while galaxies with spheroids make up ∼30%–40% across the redshift range, and pure spheroids with no evidence for disks or irregular features make up ∼20%. The fraction of galaxies with irregular features is roughly constant at all redshifts (∼40%–50%), while those that are purely irregular increases from ∼12% to ∼20% at z > 4.5. We note that these are apparent fractions, as many observational effects impact the visibility of morphological features at high redshift. On average, Spheroid-only galaxies have a higher Sérsic index, smaller size, and higher axis ratio than disk or irregular galaxies. Across all redshifts, smaller spheroid and disk galaxies tend to be rounder. Overall, these trends suggest that galaxies with established disks and spheroids exist across the full redshift range of this study, and further work with large samples at higher redshift is needed to quantify when these features first formed.

Cryptomeria japonica var. sinensis Miquel in south China is currently overwhelmingly infested by a native caterpillar species, Dendrolimus houi (Lepidoptera), which is causing severe economic losses and ecological disasters in both planted and natural forests. Our results include report of five parasitoid species and eight parasitoid flies within D. houi and a dominant endoparasitoid species Kriechbaumerella dendrolimi, which attacks pupae of D. houi with a high parasitism rate. This result might be helpful to improve better identification and application in the future for potential biological control of D. houi in the forests of east Asia.

Intestinal microbiota correction in the therapy of irritable bowel syndrome (IBS) is an important medical problem. We conducted a laboratory and pilot clinical trial to investigate the effect of autoprobiotic bacteria, indigenous bifidobacteria and enterococci isolated from faeces and grown on artificial media to use as personified food additives in IBS treatment. Convincing evidence of the clinical efficacy of autoprobiotic was demonstrated by the disappearance of dyspeptic symptoms. The microbiome of patients with IBS was compared to a group of healthy volunteers and changes in the microbiome after autoprobiotic use were detected by quantitative polymerase chain reaction and 16S rRNA metagenome analysis. The possibility of reducing opportunistic microorganisms in the treatment of IBS with autoprobiotics has been convincingly proven. The quantitative content of enterococci in the intestinal microbiota was higher in IBS patients than in healthy volunteers and increased after therapy. An increase in the relative abundance of genera Coprococcus, Blautia and a decrease in the relative abundance of Paraprevotella spp. were found at the end of therapy. A metabolome study which was performed by gas chromatography and mass spectrometry demonstrated an increase in the content of oxalic acid, a decrease of dodecanoate, lauric acid, and other metabolome components after taking autoprobiotics. Some of these parameters correlated with the relative abundances of Paraprevotella spp., Enterococcus spp., and Coprococcus spp. representative of the microbiome. Apparently, they reflected the peculiarities of metabolic compensation and changes in the microbiota. Therefore, the use of autoprobiotics for treatment of IBS may lead to a stable positive clinical effect, associated with compensatory changes in the intestinal microbiota, and accompanied by corresponding changes in metabolic processes in the organism.

Authors: Liang Austin Rong-Da , Lim Wai Mun , Tung Wei , Lin Shu-Ying
Published: March 2023

The primary objective of this study is to identify categories of organic food consumers based on the CFL (convenience food related lifestyle). Secondarily, this study explores characteristics, motivations/barriers in consumption and perception regarding to self-focus perception (such as perceived consequence of purchasing organic food) and altruistic behaviour (such as recycling behavior and perception of transportation) in different CFL. 1,262 valid samples are collected in this study. Moderate, convenience-pursuing and quality-pursuing categories are separated by cluster analysis. Consumer attitudes toward ready-made meals and takeaway meal solutions, perceived consequences of purchasing organic food, purchase frequency and quantity are differential, and the influence of organic food purchasing perception of consequence on altruistic behaviour are differences in CFL. Only consumers who purchase organic food motivated by environmental concerns are able to improve their recycling behavior. This study believes that the CFL framework has enhanced the understanding of consumer buying behavior and characteristics.
Error estimates of mixed finite elements combined with Crank-Nicolson scheme for parabolic control problems
Authors: Tang Yuelong
Published: March 2023

In this paper, a mixed finite element method combined with Crank-Nicolson scheme approximation of parabolic optimal control problems with control constraint is investigated. For the state and co-state, the order $ m = 1 $ Raviart-Thomas mixed finite element spaces and Crank-Nicolson scheme are used for space and time discretization, respectively. The variational discretization technique is used for the control variable. We derive optimal priori error estimates for the control, state and co-state. Some numerical examples are presented to demonstrate the theoretical results.
Optimal control for co-infection with COVID-19-Associated Pulmonary Aspergillosis in ICU patients with environmental contamination
Authors: Mohankumar Nandhini , Rajagopal Lavanya , Nieto Juan J.
Published: March 2023

In this paper, we propose a mathematical model for COVID-19-Associated Pulmonary Aspergillosis (CAPA) co-infection, that enables the study of relationship between prevention and treatment. The next generation matrix is employed to find the reproduction number. We enhanced the co-infection model by incorporating time-dependent controls as interventions based on Pontryagin's maximum principle in obtaining the necessary conditions for optimal control. Finally, we perform numerical experiments with different control groups to assess the elimination of infection. In numerical results, transmission prevention control, treatment controls, and environmental disinfection control provide the best chance of preventing the spread of diseases more rapidly than any other combination of controls.
Predictive modeling of reliability engineering data using a new version of the flexible Weibull model
Authors: Emam Walid , Alomani Ghadah
Published: March 2023

The combined-unified hybrid sampling approach was introduced as a general model that combines the unified hybrid censoring sampling approach and the combined hybrid censoring approach into a unified approach. In this paper, we apply this censoring sampling approach to improve the estimation of the parameter via a novel five-parameter expansion distribution, which we call the generalized Weibull-modified Weibull model. The new distribution contains five parameters and is therefore very flexible in terms of accommodating different types of data. The new distribution provides graphs of the probability density function, e.g., symmetric or right skewed. The graph of the risk function can have a shape similar to a monomer of the increasing or decreasing model. Using the Monte Carlo method, the maximum likelihood approach is used in the estimation procedure. The Copula model was used to discuss the two marginal univariate distributions. The asymptotic confidence intervals of the parameters were developed. We present some simulation results to validate the theoretical results. Finally, a data set with failure times for 50 electronic components was analyzed to illustrate the applicability and potential of the proposed model.

Published: March 2023

Cheese whey is considered the main by-product obtained by the dairy industry and it is derived from coagulation during cheese production. Half of cheese whey production is used in well-established processes, like production of fresh products, animal feed, and a source of high-added-value compounds, such as whey protein and β-galactosidase. Unfortunately, the use of cheese whey as raw material requires expensive processes. Therefore, a high proportion of this product is wasted and discarded into industrial effluent treatment stations. Different research groups have been studying potential strategies to valorize cheese whey. The goal of this chapter is to present the main characteristics of cheese whey and introduce the possibilities of using this by-product for new biotechnological purposes. The challenge is the arrangement of these processing systems with the players involved in the dairy industry. A joint action between them can turn cheese whey waste into high-added-value products producing zero dairy waste and honoring environmental legislation and public policies.

Authors: Tan Lynde , Wang Tingjia
Published: March 2023

There is a rise in the integration of augmented reality (AR) in education in recent years. This emerging medium is less explored in literacy education, yet the new textual form is necessary for adapting to the changes in the world of literacy. The chapter examines students' active use of bodily movement in AR-mediated literacy learning and addresses the issue of the relationships between literacy, body, space, and new media in a primary school classroom in Australia. The findings presented are based on the systemic functional-multimodal discourse analysis of classroom observations. Data includes the multimodal instructions provided by an AR app as well as students' work samples, specifically their AR compositions. These findings provide insights into students' agentive meaning making processes and teachers' leadership in expanding students' metalanguages in AR-mediated learning.
Getting “Unstuck”
Authors: Buechner Barton D. , Worrell-George Kathlyn , Shienko Lilya
Published: March 2023

This chapter describes development of a literacy of lived experience, applying concepts of phenomenology, somatics, and the coordinated management of meaning (CMM) theory of social construction in communication. Structured writing exercises (protocols) are used to deeply examine poignant life experiences, which had a strong impact or raised important questions for individuals as well as at the collective level. This process can further expose the presence of “moral injuries” or difficult episodes of lived experience which challenge or disrupt core beliefs impacting the sense of identity and purpose. The tools and models presented here also offer some ways to exercise self-leadership through the acquired capacity for co-constructing more coherent social realities after this type of disruptive experience. The process is illustrated with the example of a military veteran who became “stuck” in life after leaving service, a problematic experience for many transitioning veterans that also has implications for other marginalized individuals.
Privatization and Public Sector Sustainability
Authors: Prathapagiri Vasantha Gouri , Upadhayay Varsha
Published: March 2023

Privatization seems to be the current trend for most of the public sector institutions that are loss-making and a burden for the government. In fact, public sector institutions work for public welfare and not for making profits. This was proved during the pandemic period that most of the government hospitals were active in treatment given to COVID-19 patients unlike private hospitals focusing on profits. Therefore, privatization cannot be the right solution for underperforming public sector enterprises. There needs to be a partnership forged between the public and private sectors or contracting out public sector work to private institutions. This chapter focuses on privatization and public sector sustainability in the Indian context.

Published: March 2023

Colombia is an emerging country and has reflected in the last decades a significant advance for the strategic positioning of both its private organizations at the national and international level, as well as its public organizations that are guided by schemes of the new public management. The organizational approach is guided towards a better state administration, based on transparency, efficiency, effectiveness, and focus on the citizen. For this, the chapter seeks to analyze the benefits and good practices of the VRIO methodology (valuable, rare, inimitable, and organized) as a bastion of the theory of resources and capacities that guide the design, redesign, and optimization of management models of state organizations. This study was conducted under the qualitative approach with documentary analysis and interviews with experts from the state administration, finding an ignorance of this tool to increase the competitiveness of public organizations created to achieve the maximum possible social welfare.

Published: March 2023

In 2022, there were more than 4,100 data breaches that were brought to public attention, which resulted in nearly 22 billion people's information being compromised. When compared to 2021, when the number of cybersecurity specialists stood at 2.72 million, this shows a significant rise in the severity of the problem. Many businesses run the danger of having their organizations put at a “moderate” or “severe” risk of being attacked by cybercriminals due to a lack of workers. This study explores the value of cybersecurity skill and workforce development programs in high schools, especially those on Native American reservations, rural areas, urban areas, and low-income areas.

Published: March 2023

As a result of COVID-19, the leaders' needs to be adaptable and innovative with their approaches has never been more significant. These adaptive management and risk strategy approaches should also consider the importance of planning around cybersecurity. As a result of COVID-19, more commercial transactions are now conducted electronically; nevertheless, companies may utilize a number of different adaptive techniques to become more adaptive and safeguard both themselves and their stakeholders. The systematic investigation of different methods for effecting positive social change is known as intervention research. It is distinguished by the process of designing and developing treatments at the same time. The specification of the intervention is part of the design process as the intent of the approach is to improve the world of practice and not reconstitute theory within that academic discipline.

Smart Nanomaterials for Photo-Catalytic Applications
Authors: Amdeha Enas
Published: March 2023

Smart nanomaterials are grabbing more significant attention. Photocatalysts are catalysts that can be stimuli by light with an appropriate wavelength. Photocatalysis is deemed to be a promising approach for the utilization of photo energy and has been extensively studied for many processes. Therefore, the synthesis of nanomaterials with tailored-made catalytic characteristics, are of great importance. For applications using visible light and hence solar energy, the modification of photocatalysts can occur via the formation of heterojunction nanocomposites by inhibiting the recombination of charge carriers. These applications are driven by solar energy, which is conducive to the sustainable development of energy resources with no impact on the environment. This chapter will include recent enhancements in the smart nanomaterials for photocatalytic applications, especially in the fields of removing environmental pollutants, self-cleaning surfaces, water splitting for hydrogen production to provide clean fuel resources, selective alcohol oxidation and CO2 reduction in the environment.
Twitter-Based Disaster Response Using Machine Learning
Authors: Lamsal Rabindra , Kumar T. V. Vijay
Published: March 2023

Twitter, a microblogging platform, receives real-time information via informal conversations, and it has, accordingly, become the main source of data for research studies based on emergency situational awareness. Millions of tweets are posted on Twitter every day, and during disasters, the frequency of tweets relating to an on-going crisis event grows exponentially. This unprecedented increase in the number of tweets during disasters needs to be monitored, identified, processed, and analyzed so that necessary measures can be taken at the earliest to reduce the loss or damage during emergencies. However, due to large voluminous data being available during crisis hours, it is almost impossible for a human to perform these tasks in real time. In this regard, a semi-automated AI-based disaster response system for Twitter data is proposed. The proposed disaster response system would be capable of extracting essential situational awareness information related to a disaster and would also be capable of sketching tentative area of critically affected population.

Temporal Transferability of Calibrated Hydrological Model Parameters: A Case Study of Gin Catchment, Sri Lanka
Authors: Wickramaarachchi T. N. , Gunasekara S. S. D. S.
Published: March 2023

Lack of observed data for model calibration hinders the application of hydrological models in many poorly-gauged catchments, particularly in the humid tropical region. Despite much less attention given, it is vital to assess transferability of calibrated parameters in order to apply hydrological models in such catchments to assist their water resources planning and management activities. Thus, this study investigated temporal transferability of a lumped conceptual hydrological model’s (MIKE 11 NAM) calibrated model parameters for rainfall-runoff simulations in two different time periods beyond its calibration period. Study area was selected as Gin catchment located in the humid tropical region. MIKE 11 NAM model was calibrated for the period 1995-1998 [Nash Sutcliffe coefficient (NSE) = 0.73, percent bias (PBIAS) = 3.9%, ratio of the root mean square error to the standard deviation of measured data (RSR) = 0.52] and validated for the period 1999-2002 (NSE=0.66, PBIAS = 8.7%, RSR = 0.59) for the Gin catchment. The temporal transferability of the calibrated model parameters was tested using two scenarios which formulated based on the temporal lag between the calibration period and the transfer period: scenario A having a 4-year time lag and scenario B having a 8-year time lag. Scenario A which evaluated the model performance using 2003-2006 streamflow data indicated only a marginal loss in the model performance in comparison to the calibration. It showed an overall ‘good’ performance (NSE=0.64, PBIAS = 8.6%, RSR = 0.59) including promising capability to reproduce the peak flows (<10th percentile) with Pearson’s correlation coefficient of 0.6. However, scenario B which evaluated the model performance using 2007-2010 streamflow data indicated ‘unsatisfactory’ model performance (NSE=0.42, PBIAS = 13.6%, RSR = 0.76). Therefore, this study suggests that the calibrated parameters of MIKE 11 NAM model can be temporally transferred within a catchment with a 4-year time lag from the calibration period implying the applicability of this modelling framework for rainfall-runoff simulations especially in the catchments where streamflow data is sparse.

Published: March 2023

Short-term intense precipitation is one of the hallmarks of climate change. Mi Oya River basin experiences severe seasonal floods annually, but the damage can be lessened by developing a numerical weather forecasting (NWF) model for the entire basin and incorporating it with effective reservoir management. Several areas in Sri Lanka have undergone NWF studies, however they are insufficient to determine the best physics schemes for the basin. This study investigates the Weather Research and Forecasting (WRF-ARW) model's predictability with varying three microphysics and two cumulus schemes to discover the optimal set of physics parameters for predicting heavy rainfall occurrences throughout the Southwest and Northeast monsoon seasons within a nested domain configuration. The WRF model's forecasting results at 3 km grid resolution were compared with four rainfall gauging stations in the basin for three rainfall events in May 2016, April 2018, and November 2015. Total Model Performance was derived for the evaluation utilizing bias, MAE, RMSE, Correlation Coefficient, and slope of each model's output data with observed rainfall data. After comparing the model output to data, WSM6 microphysics and Betts-Miller-Janjic cumulus with other default physics settings were determined to be the optimal physics combination to forecast weather across the region.

Commuters tend to shift from public to private transport modes due to various reasons. This results in an increased traffic volume in the urban road network. The ultimate consequence is traffic congestion which creates massive economic losses and adverse environmental pollution. To provide a feasible solution for the above problems, this study is set to examine the factors affecting transport mode choice. Factor analysis was used to identify the factors influencing the mode choice variability of the commuters. Parameter estimation is done using the Multinomial Logit (MNL) model based on the utility maximization theory. The adjusted likelihood ratio index is used to show the model fits. Also, t-statistics and the respective sign of parameters are used to show the validity of estimated parameters. The outcome of the factor analysis shows that age and occupation significantly affect the public transport mode choice under personal characteristics. For private mode choice, the contributing factors are gender, age, occupation and monthly income. Trip distance, invehicle travel time, and travel cost are significantly influencing both public and private transport mode choices. Results of the estimated parameters and elasticity analysis suggest that more commuters can be attracted to public transport by reducing the total travel time of buses.
Potential Environmental Impacts of the Use and Disposal of Personal Protective Equipment during the COVID-19 Pandemic in Sri Lanka

Published: March 2023

Personal protective equipment (PPE) is a critical step in preventing the spread of COVID 19. It is a relatively new phenomenon in many countries, including Sri Lanka. However, used PPE is classified as hazardous waste due to the possibility of pathogen contamination, and the majority of them are made of PET, making them non-biodegradable waste. This study estimated the daily disposal of PPE waste and gathered data on the disposal techniques used by people, ultimately estimating the environmental impact of this newly added waste stream. Data collection was solely based on a questionnaire circulated online. Almost 12 million face masks, 0.2 million gloves, and 0.3 million face shields are used in a single day in Sri Lanka. In addition, as empty sanitizer bottles, 0.7 million PET (polyethylene terephthalate) bottles are discarded. The estimated annual climate change impact of PPE use across the country was nearly 100 kT CO2 eq. Open burning is the most common method of disposal for face masks and gloves used by households; nearly half of all used face masks and gloves are burned. Transferring waste to municipal solid waste collections also results in waste ending up in open dumps with other waste. As a result of the toxins released into the air during open burning and the release of microplastics during photovoltaic degradation, PPE disposal practices in Sri Lanka have a massive environmental and public health impact. Nevertheless, PPE can be used to generate energy through incineration or pyrolysis, reducing environmental impacts while providing economic benefits if proper plans and policies are in place.

Posttranslational modifications expand the functions of immune-related proteins, especially during infections. The respiratory glycoprotein, hemocyanin, has been implicated in many other functions, but the role of phosphorylation modification in its functional diversity is not fully understood. In this study, we show that Penaeus vannamei hemocyanin (PvHMC) undergoes phosphorylation modification during bacterial infection. Dephosphorylation of PvHMC mediated by P. vannamei protein phosphatase 2A catalytic increases its in vitro antibacterial activity, whereas phosphorylation by P. vannamei casein kinase 2 catalytic subunit α decreases its oxygen-carrying capacity and attenuates its in vitro antibacterial activity. Mechanistically, we show that Thr517 is a critical phosphorylation modification site on PvHMC to modulate its functions, which when mutated attenuates the action of P. vannamei casein kinase 2 catalytic subunit α and P. vannamei protein phosphatase 2A catalytic, and hence abolishes the antibacterial activity of PvHMC. Our results reveal that phosphorylation of PvHMC modulates its antimicrobial functions in penaeid shrimp.

Foley’s catheter and nasogastric tubes are very commonly used at every medical facility and are usually safe for the patients. Ventriculo-peritoneal shunting is the most common pediatric neurosurgical procedure. Although Shunt failure is unfortunately quite common, knotting of an intraperitoneal end of shunt tubing is very rare. We report three cases of in vivo knotting in different body cavities and possible methods to remove the catheters.

Introduction:

Sepsis is the leading cause of mortality, and various scoring systems have been developed for its early identification and treatment. The objective was to test the ability of quick sequential organ failure assessment (qSOFA) score to identify sepsis and predict sepsis-related mortality in the emergency department (ED).

Methods:

We conducted a prospective study from July 2018 to April 2020. Consecutive patients with age ≥18 years who presented to the ED with a clinical suspicion of infection were included. Sensitivity, specificity, positive predictive value (PPV), negative predictive values (NPV), and odds ratio (OR) for sepsis related mortality on day 7 and 28 were measured.

Results:

A total of 1200 patients were recruited; of which 48 patients were excluded and 17 patients were lost to follow-up. 54 (45.4%) of 119 patients with positive qSOFA (qSOFA >2) died at 7 days and 76 (63.9%) died at 28 days. A total of 103 (10.1%) of 1016 patients with negative qSOFA (qSOFA score <2) died at 7 days and 207 (20.4%) died at 28 days. Patients with positive qSOFA score were at higher odds of dying at 7 days (OR: 3.9, 95% confidence interval [CI]: 3.1–5.2, P < 0.001) and 28 days (OR: 6.9, 95% CI: 4.6–10.3, P < 0.001). The PPV and NPV with positive qSOFA score to predict 7- and 28-day mortality were 45.4%, 89.9% and 63.9%, 79.6%, respectively.

Conclusion:

The qSOFA score can be used as a risk stratification tool in a resource-limited setting to identify infected patients at an increased risk of death.

Background:

High levels of burnout, stress, and stimulant abuse have been reported among medical and dental students worldwide, with country-specific factors being contributors. The association, risk factors, and predictors of these three variables have not sufficiently been reported from Saudi Arabia, especially from the Western region.

Objective:

To determine the prevalence, association, and predictors of burnout, stress, and stimulant abuse among medical and dental students in the Western region of Saudi Arabia.

Methods:

This cross-sectional study included all second to sixth year medical and dental students enrolled at Taibah University, Madinah, Saudi Arabia, during the 2019–2020 academic year. A self-administered, closed online questionnaire was administered. Data regarding stress were elicited using Cohen's 10-item Self-Perceived Stress Scale and regarding burnout using the Oldenburg Burnout Inventory Student Version questionnaire. Multiple logistic regression model to identify the risk of burnout was conducted, and univariate and multiple linear regression models were carried out to identify the predictors of stress.

Results:

Of 1016 eligible students, 732 responded (medical: 511; dental: 221). About half of the students experienced burnout (51.5%), with both high disengagement (49%) and exhaustion (45%). Most participants (90.3%) experienced moderate levels of stress. Eight (1.1%) respondents had experienced stimulant abuse; there was a no significant association between stimulant abuse and burnout in the multivariate analysis. Stress, age, gender, body mass index, GPA, study field, smoking, family income, and birth order were significant predictors of burnout, while burnout, age, gender, GPA, and physical exercise were significant predictors of stress.

Conclusion:

The findings in this study highlight the need for policymakers to devise strategies that target early identification as well as reduction of the high levels of burnout and stress.

An uncommon kind of cancer called angiosarcoma originates in the lining of lymph and blood arteries. The immune system includes the lymphatic vessels. The lymph vessels remove waste materials, viruses, and germs from the body. Any region of the body can develop cancer of this kind. Angiosarcoma is an aggressive tumour, It is a form of soft tissue sarcoma. The treatment of angiosarcoma is very difficult. Breast cancer arises in the breast's lymphatic or blood vessel networks eventually migrating to the breast and the skin of the arms. Most angiosarcomas have unknown origins. Researchers have found a number of variables that could raise the disease's risk. Angiosarcoma develops when the DNA of cells lining a blood artery or lymph channel changes. The instructions that inform a cell what to do are encoded in its DNA. The adjustment which scientists refer to as mutations, instruct the cells to divide quickly. When healthy cells would perish, the alterations prevent the cells from dying. As a result, cancer cells can accumulate and spread outside of the blood vessel or lymph channel. Cancerous cells are able to infiltrate and obliterate healthy body tissue. Cancer cells could eventually separate and travel to different parts of the body. Angiosarcomas have a rapid development rate and body-wide dissemination. Breast angiosarcomas come in two varieties, primary and secondary, and they are both treated surgically by removing the tumour. Angiosarcoma can be spread in other part of body from breast. Primary breast angiosarcoma is an uncommon kind of breast cancer that only affects women, typically developing in the third to fourth decade. For diagnosis, biopsy, mammogram, breast MRI, PET Scan, ultrasound were performed and for the treatment of breast cancer surgery, chemotherapy, radiotherapy were performed. Only 0.04% of malignant breast tumours are primary breast angiosarcomas, making it a rare form of breast cancer. Secondary malignant tumour growth is one of the dangers of therapeutic radiation. In this paper, various cases are reported of angiosarcoma of the breast.

Authors: Cornelius Tamekka L. , Mitchell Donald “DJ”
Published: March 2023

Within this multiple-case study, we explored the experiences of Black women in senior student affairs officer (SSAO) positions at four-year historically white institutions (HWIs) and Historically Black Colleges and Universities (HBCUs) in the United States. We used Black feminist thought and representational bureaucracy to theoretically frame the study. Participants included SSAOs representing three HWIs and two HBCUs. Four central themes—often expressed within experiences of marginalization—emerged across the cases: 1) I Have a Right to Be Here; 2) Creating Networks; 3) No Straight Line to the Top; and 4) I’m Thinking about the Black Girls Coming Behind Me. We conclude the study with a discussion, implications for practice, and recommendations for ongoing research.
