Published: October 2021

Background: Parental engagement is one of the key factors that can influence adolescents mentalhealth status, although these associations are not fully measured in the local context. This study willestimate the prevalence and association of parental engagement with adolescents and mental healthstatus in Sri Lanka. Method: This current study is a secondary analysis of nationally representativedata for Sri Lanka. The data was collected from 3262 school attending students in grades 8-12 inthe Sri Lankan Global School-based health survey (GSHS) 2016. A two-stage cluster sample designwas used to select the representation of samples. The binary variables i.e. loneliness, anxiety andsuicidal ideation, were modelled using multivariable logistic regression models with predictorsrepresenting gender, age, grade, parental supervision and parental understanding. Result: It isestimated that the prevalence of parental supervision and parental understanding is 85.3% and78.5%, respectively. The analysis of both good parental supervision and parenting understandinghas reduced the loneliness, anxiety and suicidal thoughts among the adolescents population,compared to those who don't have good parental engagement. Conclusion: It is seen that there isa higher prevalence of parental and children engagement in Sri Lanka compared to otherdemographical regions. However, the prevalence of mental health remains higher as compared tothe global average. The results suggest that national policies and programs should be integrated forboth parents and children. Parents need more knowledge on good parenting, while adolescents needsupport on coping with their mental health.
APPLICATION OF SYSTEMATIC APPROACH IN THE PROCESS OF FORMING THE READINESS OF AFU FUTURE OFFICERS FOR PROFESSIONAL ACTIVITY: THEORY AND PRACTICE
Authors: Ryzhykov V. , Didenko O.
Published: October 2021

The article discusses the use of the system approach of future officers training in higher military educational institutions, analyzes the basic principles of the pedagogical system, which are defined by the system as a holistic organized set of military training, which ensures stable behavior and effective results of military education. The basic systems of professional training in higher military educational institutions, which have the conditional level of involvement in the educational process, are revealed. However, the basis is the inalienability of all systems in the training of future officers of the Armed Forces, and the interchangeability or absence of any training system leads to irreparable consequences, the result of which is not fully formed professional readiness of an officer of the Armed Forces. Theoretically, professional readiness is formed as knowledge, skills and competencies fully acquired, but the important point remains whether psychological professional readiness is formed during the extreme situation of military service. In view of the material presented in the scientific article, the conclusion is that the training of officers of the Armed Forces in higher military educational institutions is a system one. The result of the training process of future officers in higher military educational institutions is a high level of cadets readiness for practical activities,
which can be achieved only by streamlining the system on the basis of certain principles to which we include: the principle of objectivity, completeness, specific historical (genetic) approach, systematics, contradictions of pedagogical experience. This makes it possible to organize the specific functioning of all subsystems of future officers training and their effective interaction in accordance with the aspect and general goals and objectives. When modeling the system approach of professional training in higher military educational institutions the main pedagogical systems (types of training) involved in the training of officers of the Armed Forces are used. Each of them has its purpose and objectives, specific content, means and methods. Because the
professional training of future officers of the Armed Forces is an integration process of formation of the same five basic systems (theoretical, psychological, physical, training and practical (officer training in combat units)).

Pandemic in the Context of on Environmental Consciousness
Authors: Mdivani M.O. , Alexandrova E.S.
Published: October 2021

The article is directly related to the subject of common interest — COVID-19 pandemic, which significantly impacts the entire world community. In the paper, we consider the spread of coronavirus infection as one of the consequences of active use of the natural environment and its resources by humans. Psychologically, the current ecological crisis stems from the regularities of the human consciousness formation. The present study empirically examines the impact of the COVID-19 hazard estimation on the nature-human interaction assessment. The study involved 372 participants (42% men and 58% women), the mean age of the subjects was 33.9 years (SD = 11.4 years). The data obtained shows that the perception of COVID-19 as a serious disease is associated with the apprehension of nature as adverse for humans, fear of natural forces (F = 12.307; p < 0.001), — perceptions characterizing the archaic type of environmental consciousness. At the same time, younger people assess the negative impact of nature on humans significantly lower than the older respondents (chi-square = 14.041; p < 0.001), and at the same time, recognizing the danger of the coronavirus, they are concerned about the natural environment preservation, demonstrating an ecocentric type of environmental consciousness.
Longitudinal Study on the Development of Giftedness
Authors: Bogoyavlenskaya D.B. , Artemenkov S.L. , Joukova E.S.
Published: October 2021

The article is devoted to the study of giftedness as the ability to create. The relevance of the topic is determined by the state program for the identification and support of gifted children. A longitudinal study of children aged 8—12 years (n = 42) using the “Creative Field” method allows us to trace the formation and development of their giftedness. This method allows for a differentiated diagnosis of the ability to develop activities on their own initiative (heuristic level of activity) or its absence (stimulus-productive level of activity). Intelligence was assessed by J. Raven’s test and the indicators of learning ability of the “Creative Field” method. In connection with the widespread understanding of giftedness, which reduces it to a high level of intelligence, a hypothesis was put forward about the range of IQ indices, which may be wider in the stimulus-productive group than in the group of heurists, but its upper bounds for these groups should be close. High values of intelligence in both groups are the basis for the conclusion that it is impossible to reduce giftedness only to a high level of intelligence. Giftedness is manifested in the integration of intelligence, the lower limit of which is determined by the ability to master the proposed activity, with the dominant cognitive motivation in the personality structure.

The article presents the results of the study of social media discourse in the context of the COVID-19 pandemic, which reflects opinions, perceptions, assessments of current events and makes a significant contribution to their formation. The aim of the study was to identify the peculiarities of the organization of discourse during the vaccination campaign, which related to the intentional orientation of the subjects of communication. The material of the study — 5 information messages about the vaccination against COVID-19 and their discussion on various Internet sites (126 people; 248 comments, М= 50, min=46, max=52). Using the method of intent analysis, it was found that the discussion of messages about vaccination was accompanied by the appearance of additional topical and interactive objects and a multiple increase in the number of realized categories of intentions. The prevalence of neutral intentions to analyze the problematic situation, to present and compare the positions, demonstrating the change in the tone of the discourse from the epidemic beginning, was detected. The leading role of interactive objects was identified, which indicated the presence of dialogic intentions and the needs for joint comprehension of the events.

Published: October 2021

The article presents research data on the identification of personality determinants of various types of deviant behavior of students of secondary vocational education institutions. The study is retrospective because based on the recorded objective manifestations of various types of deviant behavior of students during their training in an educational institution. The study involved 82 students — boys and girls aged 15 to 17 years. We studied the following types of deviant behavior: socio-psychological maladaptation, primary deviation, addictive behavior, aggressive behavior and delinquent behavior. Objective indicators for each type of deviant behavior were recorded on the basis of the personal data of students. Personal- ity determinants were evaluated using psychological testing techniques. The study found that the most common types of deviant behavior are primary deviation and delinquent behavior. The study found that the personal determinants of the socio-psychological maladaptation of students are dominance, affection, cooperation, respect for others, carefree, emotive and curious; primary deviation — the manifestation of feelings, plasticity; addictive behavior — a tendency to overcome norms and rules, a violation of volitional control of emotional reactions; aggressive behavior — respect for others, expressiveness, artistry, demon- strativeness, excitability, emotiveness, a tendency to self-destructive behavior; delinquent behavior — cooperation, respect for others, dymism cyclotymic, a tendency to overcome norms and rules, a tendency to addictive behavior. Common personal determinants that are characteristic of different types of deviant behavior are cooperation, respect for others, emotionality, a tendency to overcome norms and rules, hypertimity, cyclotimicity, stuck and exalted.
Platform Law and Platform Solutions in the Fight against the Pandemic
Authors: Altoukhov A. V. , Kashkin S. Yu. , Molchanov N. A.
Published: October 2021

The paper looks at the impact of the coronavirus pandemic, focusing upon the invaluable contribution of the platform technologies and artificial intelligence to the fight against this suddenly impending threat. Applying analytical techniques, we focus on some Asian countries (i.e. Singapore, China), Russia and the USA. The results demonstrate that rapid processing of large amounts of data, standardization protocols and quick analysis within a tight deadline cannot be overestimated. However, lack of the appropriate legal regulation significantly limits the functionality of platform solutions. We live in a modern legal state, where human rights arerecognized as the highest value, so implementation of new technologies, regardless of their efficiency and practical value, should not infringe the rights of citizens, but meet the requirements of the law. The article tackles the problem of global COVID-19 pandemic by focusing on the international experience in the use of artificial intelligence and arising legal issues associated with human rights and information privacy laws. This will help to determine the vector of the legislation development globally among the continents and in the Russian Federation specifically.
The Legal and Institutional Foundations of Silicon Valley’s Technological Innovation: An Interdisciplinary Literature Review
Authors: Stone S. D.
Published: October 2021

This article reviews interdisciplinary literature to explain how state legislation and the practice of law in California influenced the success of Silicon Valley in creating a startup business culture involving the commercialization of technologies built on venture capital finance. Scholarship has identified four major factors in the rise of Silicon Valley: business culture, symbiotic institutional relations with research universities, California contract and employment law, and Silicon Valley law firm culture. Both law and institutional support have been central to the commercialization of scientific knowledge that is the hallmark of Silicon Valley. Silicon Valley companies have remained leaders in technological innovation for over sixty years, encompassing various technologies from semiconductors to personal computers to the Internet. This entrepreneurial approach to technology continues to this day as exemplified by the successful DoorDash and Airbnb IPOs launched in 2020. The paradigmatic Silicon Valley technology company consists of a small group of entrepreneurs building a start-up technology company funded by a venture capital fund. The venture capitalists (VC) maintain hands-on management of the company and receive seats on the board of director and preferred stock rights. If the business plan is successful, the company offers shares to the public through an initial public offering (IPO), or arranges additional funding from another VC fund. This Silicon Valley model is characterized by a tolerance for failure and high labor mobility. Technology company employees have the freedom to leave established companies to start their own ventures.

Published: October 2021

Ultrasonic-based techniques allow the prediction of the energy required to break the aggregate and have been more commonly used to measure the stability of aggregates. Although they result in the same applied energy, certain combinations of time and power might correspond to different intensities of cavitation. Consequently, different responses in aggregation indexes can be obtained with different configurations of ultrasound techniques. Thus, this work was carried out to evaluate the effects of cavitation intensity in the distribution of aggregates of a Paleudalf under management systems with cover plants and to compare aggregate stability determination methods (ultrasound versus wet sieving). Aggregate samples of the BS (bare soil), OT (black oat + forage turnips) and OV (black oat + hairy vetch) treatments were exposed to ultrasonic irradiation in different combinations of potency and time: (U1) 74.5 W/4 s; (U2) 49.7 W/6 s; (U3) 74.5 W/10 s and (U4) 49.7 W/15 s. After each sonification, the samples were passed in the same set of sieves used in the standard method of wet sieving -WS (8.00 - 4.76, 4.76 - 2.00, 2.00 - 1.00, 1.00 - 0.25 and < 0.25 mm) and the geometric mean diameter (GMD) and mass-weighted mean diameter (WMD) were calculated. The amplitude of vibration exerted a greater influence on soil breakdown than the total energy applied. Compared to the ultrasound method, in the WS method observed higher percentage of retained aggregates in the size class 8-4.76 mm and, consequently, greater aggregation indexes GMD and WMD.

Published: October 2021

Research aims: This study aims to examine the effect of corporate governance, specifically relating to the ownership structure and board structure, on the possibility of financial distress.Design/Methodology/Approach: The sample used in this study are companies listed on the Indonesia Stock Exchange (IDX) from 2015 to 2019, excluding the financial industry. Conditional logistic regression is used as the study uses paired data based on the total assets of the company.Research findings: The results of this study indicate that board ownership, independent commissioners, and the board of directors can increase the likelihood of financial distress. On the other hand, institutional ownership and concentrated ownership are proven to have no effect on the likelihood of financial distress. The results of sensitivity testing using logistic regression showed different results on the variable institutional ownership, which is that institutional ownership can increase the likelihood of financial distress. Meanwhile, the other variables showed the same outcome as the main regression used in this study.Theoretical contribution/Originality: This study contributes to the knowledge on the relationship of board ownership, institutional ownership, concentrated ownership, independent commissioners and board size and the possibility of financial distress. Also, this research found that the provision of incentives in the form of shares to the board may not be an effective way to overcome financial distress in Indonesian firms.

Authors: Delgadillo-Aya Claudia Lorena , Espinosa C , Díaz V , Ruiz M , Marique E
Published: October 2021

En la última década se ha avanzado en la implementación de procesos de recobro químico en Colombia, incluyendo pilotos de inyección de geles obturantes para conformance químico, geles de dispersión coloidal, polímeros, álcali y surfactantes. Estos procesos han sido de marcada relevancia tanto para la promesa de incrementar el factor de recobro de los campos colombianos, como para revisar campos en sus planes de abandono mediante la aplicación de nuevas tecnologías. No obstante, estudios experimentales a condiciones de yacimiento han evidenciado que existen limitaciones para la aplicación de estas tecnologías principalmente en lo referente a: calidad del agua de inyección, salinidad del agua de formación, temperatura, entre otras; esto dificulta establecer la viabilidad técnica y/o económica de su implementación en activos con alto potencial de reservas y posibles escenarios de expansión. Por lo anterior y debido a la necesidad de incrementar las reservas de crudo, contribuyendo al entendimiento y desarrollo del recobro mejorado de hidrocarburos en el país, este artículo presenta una revisión de las limitaciones de las tecnologías de recobro químico convencionales, las oportunidades de las nuevas tendencias que permiten superar limitaciones técnicas y operacionales; además, de una estimación del potencial de las tecnologías emergentes evaluadas en el contexto nacional. Para esto, mediante la comparación de las ventanas operacionales de las tecnologías con las propiedades petrofísicas de los campos colombianos, fue posible establecer el potencial de incremento de reservas por efecto de la aplicación de nuevas tecnologías. Adicionalmente, se identificaron las necesidades en el diseño e instalación de nuevas facilidades para el tratamiento, almacenamiento e inyección de los químicos y sus costos asociados; teniendo como premisa que la aplicación de una nueva tecnología de recobro en este caso está condicionada a una viabilidad técnico-económica que permita aprovechar las facilidades existentes en campo optimizando en los posibles CAPEX (del inglés Capital Expenditures) asociados a los proyectos.

El principal aporte de este trabajo se centra en el resumen y organización cronológica de los principales temas en torno al problema de la excesiva producción de agua de los yacimientos petroleros y del uso de sistemas gelificantes para su control.
Aspectos ecológicos del uso de sorbentes para mejorar la eficiencia de bioremediación de suelos contaminados por petróleo
Authors: Mikhedova Elizaveta , Maria Uzorina
Published: October 2021

Nowadays, polluted soils are one of the primary environmental problems. Due to a large number of oil-contaminated lands, new methods are being developed more and more actively, as well as a combination of various existing methods for disposing of oil spills. In this paper, bioremediation with the use of adsorption is considered to reduce toxicity and accelerate the processes of microbial destruction of hydrocarbons. There is a large selection of sorbents based on carbon, mineral, and natural materials. The effectiveness of a particular sorbent will vary depending on the application region, weather and climate conditions, soil type, and the type and properties of the oil. In this work, peat was tested as an organic sorbent (S1), vermiculite as a mineral sorbent (S2), and sorbent based on carbon (S3). The sorbents were added to the soils contaminated by oil, evaluating the pH, humidity, and phytotoxicity of the soils. The results showed that the soils treated with sorbents maintained the neutral pH, increased the humidity, and decreased the phytotoxicity of the soil. The sorbent efficiency was S3> S2> S1.

Published: October 2021

The purpose of the article is to assess the current challenges in the implementation of the Digital Culture Environment among the rural community in Malaysia. The Covid-19 pandemic has changed the online environment where a drastic usage of digital tools has been observed among Malaysian. The digital culture is defined as the culture shaped by the emergence of digital technologies and their usage in the community. The literature survey approach has been applied as the methodology of study to explore the current challenges in the implementation of the Digital Culture Environment among the rural community in Malaysia. Several challenges have been identified, including the rural sustainable issues, digital divides, demographic factors, Information, Communication and Technology (ICT) factor, individual, as well as behavior factor. According to the literature review conducted, these challenges have been revealed to significantly hurdle the government’s movement in implementing the digital culture within the rural community. To overcome these challenges, a strong and effective supporting model should be formulated to assist the government in building and establish a digital culture environment in Malaysia, particularly among the rural community. Hence, a further in-depth study is required to acquire comprehensive literature information to address this issue.

Authors: Niknami Mahdi , Emami Elham , Mozaffari Abdolhosein , Sharifian Hashem , Safari Sanaz
Published: October 2021

Objectives: This study aimed to evaluate the correlation between the opacification degree of the paranasal sinuses on computed tomography (CT) with clinical symptoms, and anatomical variations of the nose and paranasal sinuses in patients with chronic rhinosinusitis (CRS).
Materials and Methods: This descriptive prospective study evaluated 100 patients (60 males and 40 females), who were diagnosed with CRS by ENT specialists according to the clinical findings, and were scheduled for a CT scan. The patients were requested to express the severity of their symptoms using a visual analog scale. The CT scans of the paranasal sinuses were assessed for the presence of anatomical variations and scored using the modified Lund-Mackay scoring system for the opacification degree of each sinus. The correlations between the anatomical variations and sinusitis, and also between the severity of symptoms/disease severity and CT scores were statistically analyzed. P<0.05 was considered statistically significant.
Results: The most common symptoms were purulent (discolored) nasal drainage and nasal obstruction. Septal deviation was the most common anatomical variation. The maxillary and anterior ethmoid sinuses were the most commonly involved areas. The Spearman’s correlation coefficient showed a significant correlation between the sinus involvement and some of the evaluated symptoms, as well as certain types of anatomical variations (P<0.05).
Conclusion: Some specific anatomical variations of the paranasal sinuses may predispose them to sinusitis. The CT scan score can predict the severity of many symptoms such as purulent (discolored) nasal drainage, nasal obstruction, hyposmia/anosmia, halitosis, cough, and fatigue, among the other symptoms of CRS.

Published: October 2021

Introduction: This study aimed to assess the association between the survival of patients and outcomes in Brain Stroke (BS) in the presence of competing risks utilizing a Weibull parametric model.
Methods: In this longitudinal study, 332 patients with BS were attended from Imam Khomeini Hospital in Ardabil, Iran. The stroke was diagnosed according to the medical history, current symptoms, and brain imaging during June 2008 and 2018. The survival of the patients, as the primary outcome, was modeled utilizing the best-chosen Weibull model in the presence of competing risks, including stroke and other factors (heart disease, blood pressure, etc.).
Results: Older age at diagnosis (59-68 years: hazard ratio [HR]=2.27; 90% confidence interval [CI]: 1.65 to 3.12; 69-75 years: HR=4.79; 95% CI: 3.56 to 6.44; ≥76 years: HR, 4.92; 95% CI: 3.55 to 6.80), being a male (HR, 1.39; 95% CI: 1.11 to 1.75), being unemployed (HR, 1.44; 95% CI: 1.39 to 1.82), having heart disease (HR, 1.68; 95% CI: 1.38 to 2.06), and hemorrhagic stroke (HR, 2.21; 95% CI: 1.378to 2.75) were directly related to death from BS. Older age at diagnosis (59-68 years: HR, 18.01; 90% CI, 5.33 to 64.92; 75-69 years: HR, 18.56; 95% CI: 6.97 to 86.57; ≥76 years: HR, 28.90; 95% CI: 15.77 to 218.49), and urban residence (HR, 0.46; 90% CI, 0.28 to 0.77) were directly related to death from other causes.
Conclusion: The recognition of the influential factors on the mortality of BS patients can allow increasing their survival.
Application of Multivariate Generalized Linear Mixed Model to Identify Effect of Dialysate Temperature on Physiologic Indicators among Hemodialysis Patients
Authors: Hamidi Omid , Borzu Seyed Reza , Maroufizadeh Saman , Amini Payam
Published: October 2021

Introduction: One of the complications of hemodialysis treatment is hypotension, which can increase morbidity and mortality and compromise dialysis efficacy. Dialysate temperature is an important factor that contributes to hemodynamic stability during hemodialysis. This study investigated the effect of dialysate temperature on the patients' blood pressure and pulse rate. Model-based approaches were used to produce more reliable results compared with traditional methods.
Methods: A total of 30 patients were studied during 9 dialysis sessions. Dialysate temperatures were 37° C, 36° C and 35° C. A joint longitudinal model was used to analyze both responses of blood pressure and pulse rate, simultaneously.
Results: The results showed that low-dialysate temperature was not significantly associated with higher systolic blood pressure (p>0.05) or a higher pulse rate (p>0.05) either during or after dialysis. Pulse rate and blood pressure were higher for women during dialysate (p<0.001). However, increasing age was associated with higher blood pressure and a lower pulse rate (p<0.001).
Conclusion: Using several separate, repeated measure analysis of variances may produce misleading results, when there is more than one response variable measured over time, Multivariate statistical methods (including joint longitudinal models), should be used.

Methods: A hospital-based retrospective study was conducted on 524 patients with type II diabetes, aged 18 years or older, who attended their medication between January 1, 2005, and December 31, 2017. Multistate models with different assumptions were considered to explore the effects of different prognostic factors on the transition intensity of type II diabetes mellitus patients.
Results: During a median follow-up time of 7.4 years (Inter-Quartile Range=4.01), 54.8% of diabetic patients developed either microvascular or macrovascular complications, and 10.5% of them experienced both microand macrocomplications, and 16.66% of diabetes patients died. The assumption Markov was assessed by using the likelihood ratio test showed that Markov assumption was not held just for the transition. The transition rate of patients from the macrovascular state to the death state was affected by the residence of the patients (P=0.05) and age at diagnosis (p=0.01). The transition rates of patients with microvascular complications to death were significantly affected by baseline triglyceride level (P<0.001), age at first diagnosis (P=0.01), baseline glucose level (P=0.03, and baseline serum creatinine level (P=0.04).
Conclusion: The semi-Markov model fitted the data well and could be used as a convenient model for the analysis of time to diabetes-related complications or death.
How to Reduce Misinterpretation of Quantitative Infection Risk by Assessment Parameters Associated with the COVID-19 Pandemic
Authors: Rassow Jürgen
Published: October 2021

Introduction: The quantitative information on the risk of infection in the COVID-19 pandemic is calculated currently exclusively on the base of new infections per day, which only contribute 6.60%±1.34% to the 100% contagious acute infections and are, therefore, not proportional to the risk of infection. All methods and results presented here are shown for data in Germany, but can be transferred to any other region worldwide.
Methods: More precise parameters as are used at present, are based on acute infections: stress index with information about the distance to the stress limit of the health system, the density of the sources of infection and the change in acute infections during the last 5 days are suggested here.
Results: The comparison of the results of the current and the new assessment parameters shows that large daily fluctuations in new infections of up to ±22% lead to unnecessary uncertainties. The new assessment parameters are correspondingly more precise. The 7-days incidence warning thresholds introduced by German law in November 2020 and April 2021 are defined on the base of new infections. As a result, the real infection risks can be incorrectly assessed due to the large fluctuations of the 7-days incidence values up to ±23%, so that legal conflicts can arise if legally prescribed protective measures are objectively unjustified or introduced too late.
Conclusion: By moving from new infections to acute infections as a base for calculation, infection risks can be described more precisely and even unjustified, expensive protective measures can be avoided.

Background & Aim: Routine treatment of burn injuries is dressing with Nitrofurazone ointment. It has several complications, including sensitivity. Aloe Vera is a traditional treatment for wound healing.  This study aimed to compare the effectiveness of Aloe Vera gel with Nitrofurazone ointment in the healing of superficial partial-thickness burns.
Methods & Materials: The present study was a split body controlled clinical trial which was carried out on 30 patients with superficial partial-thickness burns. The study was conducted in the Shafa Hospital in Kerman, Iran, in 2016. The sample was recruited from patients who had at least two burns, each burn on an alternate side of the body. On their burns, samples were allocated to two groups that received Aloe Vera gel or 2% Nitrofurazone ointment. Bates-Jensen Wound assessment tool was used to evaluate the healing of burns. Statistical analysis was conducted by SPSS-16 and using the repeated measure ANOVA.
Results: The repeated measure ANOVA showed that there was a significant change in the score of BWAT in all areas during the intervention period (p=0.001), but the trend of healing in the two groups during the intervention period was not significantly different (p=0.098).
Conclusion: Based on this study, it looks like Aloe vera gel is as effective as 2% Nitrofurazone ointment in healing wounds.
The effect of rosemary ointment on the pressure ulcer healing in patients admitted to the intensive care unit: A randomized clinical trial
Authors: Khoshoei Parizi Fatemeh , Sadeghi Tabandeh , Heidari Shahin
Published: October 2021

Background & Aim: Pressure ulcers have been identified as one of the most important and challenging issues in patient’s well-being. Based on the evidence, rosemary extract compounds can affect wound healing. The aim of this study was to determine the effect of rosemary ointment on pressure ulcer healing in patients admitted to the intensive care unit.
Methods & Materials: In this single-blind randomized parallel clinical trial, 70 patients who met the inclusion criteria were selected purposefully and assigned to the groups by stratified randomization method. In the intervention group, rosemary ointment was applied once a day for seven days. The control group received routine care. Data were collected using the Pressure Ulcer Scale for Healing before the intervention and on the third and seventh days after the intervention. Data were analyzed using independent t-test, chi-square test, and two-way repeated measurements ANOVA with SPSS 18 software.
Results: The mean scores of Pressure Ulcer Scale for Healing decreased significantly in the intervention group while remained unchanged in the control group (P=0.001) one week after the intervention. The effect of time and interaction effect was also significant (P=0.001). Comparison of the ratio of complete ulcer healing in the two groups showed a significant difference between the two groups (p=0.004).
Conclusion: Rosemary ointment facilitated healing and prevented the progression of grade І pressure ulcers in the Intensive Care Unit. Therefore, the use of this ointment as a low-risk, uncomplicated, available, and inexpensive intervention, is recommended in such patients.

Background & Aim: The current study aimed to investigate workplace bullying, specifically verbal abuse of working nurses, and its consequences on the physical and psychological levels.
Methods & Materials: A cross-sectional study was designed and implemented in 151 nurses working at a university hospital. The survey was conducted in 2018 at a university hospital in Greece, and the Verbal Abuse Scale (G-AVQ v.0/2015) was used to assess the verbal abuse level. Multiple linear regression analysis was applied, and distributions were tested for their symmetry using Blom's method (QQ plot).
Results: 88.1% were women as the mean age of all was 41.7 years and 16.1 years the mean length of employment. Almost all nurses (94.7%) reported experiencing verbal abuse, as 77.6% reported that the perpetrator was a patient's relative (p<0.05). Among cognitive assessment, coping, severity of effects, and strength of feeling, coping had the highest mean value the highest mean value, while severity of effects had the lowest (2.52 vs. 1.83, p<0.05). Multiple linear regression analysis showed that frequency of verbal abuse type has a significant correlation with higher coping (β=0.28, p=0.007) and strength of feeling values (β=0.29, p=0.010). Similarly, the severity of verbal abuse type has a significant correlation with higher strength of feeling values (β=0.30, p=0.014).
Conclusion: Almost all the nurses reported experiencing verbal abuse as the 'patients' relatives were the main perpetrators. Although the nurses seem to cope with verbal abuse successfully, this fact is described as stressful. Moreover, the frequency, severity of verbal abuse, and consequences are correlated to the emotions that arise from it.
Using Logbooks to Enhance Students’ Learning: Lessons From a Mixed-methods Study in an Undergraduate Surgical Rotation
Authors: AbdulAzeem Abdullah Omer Ahmad
Published: October 2021

Background: Logbooks are frequently used in medical education to enhance and monitor students’ learning. However, some barriers that may diminish their benefits have been reported. This study aims to evaluate the usefulness of logbooks to students’ learning and identify the factors, which may contribute to their outcomes in learning milieus.
Methods: The study used a mixed-methods approach. Quantitative and qualitative data were collected from the medical students in the fourth- and sixth-year classes and their teachers in the department of surgery at the Faculty of Medicine at University of Tabuk in the academic year 2016–2017. Data were collected using questionnaires, focused group discussions, and personal interviews.
Results: Eighty-nine (49 fourth year and 40 sixth year) students and six teachers participated in the study. Logbooks were perceived as useful to students’ learning by 83.3% of the teachers and 75.3% of the students. Logbooks enhanced students’ learning through identification of areas of weaknesses, encouraged seeing more patients’ problems and reading in-depth about some topics, and improved students’ writing skills. Barriers to learning from logbooks included poor-quality feedback, no opportunities for feedback discussion, and unfair marking. Differences in the students’ perceptions of the usefulness of logbooks were observed based on their learning stage.
Conclusion: Logbooks are useful to students’ learning in many aspects; however, certain factors could diminish their benefits. Students’ attitude toward the logbook was more favorable during their early clinical experience. Faculty development programs and careful supervision of students’ work may improve the outcome of logbooks in clinical placements.

Intraosseous Hemangioma of Nasal Bone: Unusual Location of a Common Tumor with Literature Review
Authors: Abdullah M. Osman Tagwa , Fatima Sohaila , Wajih Siddiqui Shiza
Published: October 2021

Hemangiomas are very common benign vascular tumors of head and neck. Intraosseous hemangiomas are rare and very few cases of involvement of nasal bone have been found in literature. A slowly growing hard nasal mass should draw clinical suspicion and should be included in differential diagnosis as it carries with it the risk of uncontrollable hemorrhage during surgical procedures. Clinical examination and radiology are contributory but histopathological examination is confirmatory for diagnosis.
