Published: May 2022

Background: To assess the prevalence of the most common sources of stress among graduating final year medical students and to compare the students on gender and on a relative belonging to a medical profession. Methods: Students from two consecutive batches of final year MBBS were requested to complete a self-developed questionnaire about the various sources of stress. The study commenced from September 2018 to January 2020. Results were entered and analyzed in SPSS version 23. Descriptive statistics and independent samples T-test were used to analyze the data gathered. Results: A total of 194 (102 female, 92 male) final year MBBS class students participated in the study. The three most common sources of stress reported were; dealing with the practical life after graduation; encountering senior doctors as bosses and the highest expectations of their family/friends. Nearly two thirds of students reported high over stress levels. Female students were significantly more likely to report higher overall stress levels. On individual stress related items, females were significantly more likely to be stressed about the practical life ahead, about not feeling capable enough to deal with human life, about actual encounter with patients, and about encounter with senior doctors as their bosses. Students who had a parent or a sibling who was a doctor were significantly more likely to be stressed about the highest expectation of family friends. Conclusions: A significant number of final year medical students are highly stressed about the transition to working life. Female medical students are more likely to report overall stress as well as on particular stress related aspects of practical life and undergraduate training.

Published: May 2022

Objective: The objective of our study is to compare the surgical outcomes of two surgical techniques namely Fisher’s technique and Millard’s Rotational Advancement Flap, particularly in terms of white roll symmetry, lip length, lip height, scar quality, notching, cupids bow and alar base symmetry. Study design: Prospective Randomized Clinical Trial study. Place and duration of study: Department of Pediatric surgery, Sheikh Zayed Hospital, Rahim Yar Khan for a period of six months from 1st March 2021 to 31st August 2021. Patients and method: A total of 56 patients were enrolled in the study, equally divided into two groups. Group 1 will include patients undergoing treatment via Millard's Rotational Advancement Flap technique, while group 2 will include those receiving Fisher's procedure. A single consultant performed the procedure. Variables like lip length, Alar base symmetry, scar quality, cupids bow symmetry, and notching were accessed postoperative via the Steffensen grading method, and Vernier caliper was used for anthropometric measurements. The SPSS v 23 was used to evaluate the data. All numerical data were provided in mean and standard deviation (SD) formats. Frequencies were computed for qualitative data. Nonparametric tests (paired and unpaired t-tests) and parametric tests (Fisher's exact test) were utilized to compare the variables. P-value of < 0.05 was considered statistical significant. Results: Both groups had identical outcomes in terms of lip length, nasal symmetry, and alar dome. On the other hand, Fisher's approach was superior in terms of vermilion roll symmetry, white roll symmetry, scar appearance, and Cupid Bow. Anthropometric measures, such as lip height and breadth, were taken; however, the results were statistically insignificant. There was no discernible difference between the outcomes of complete and incomplete cleft lip. Conclusion: We propose using the Fisher's surgical method in unilateral cleft lip repair since it produces better outcomes than the Millard's procedure. Keywords: Anthropometric measurement; Fisher; Lip Notching; Millard; Scar; Unilateral cleft lip.

Authors: Anyaehie Michelle N , Pardo Christian , Kaufman Daniel E , Piper Brian J
Published: May 2022

Introduction

The US opioid overdose epidemic has risen to an all-time high. Prescription opioids often serve as a gateway to illicit opioids, which have appreciable overdose potential. Recent investigations have highlighted the efficacy and safety of cannabis-based products for pain management. Providing alternative pain treatment options may help mitigate the opioid epidemic.

Methods

The distribution of codeine, fentanyl, hydrocodone, morphine, and oxycodone per 100 000 people and by 3-digit zip codes from 2014 to 2018 in California and Texas were compared. Overdose rates were also evaluated. California legalized recreational marijuana in 2016, but in Texas marijuana is functionally prohibited. Drug weights were obtained from the Automation of Reports and Consolidated Orders System and converted to oral morphine milligram equivalents. Overdose data was retrieved from the Centers for Disease Control’s WONDER database.

Results

California and Texas showed significant reductions in cumulative opioid distribution from 2014 to 2018 (− 43.7% and − 27.3%, respectively). Opioid distribution per 100 000 people decreased − 38.9% in California relative to − 26.4% in Texas. Opioid and heroin overdoses increased between 1999 and 2019 by + 11.6% in California but + 272.7% in Texas.

Discussion

This evidence supports marijuana legalization as a mitigating factor to the opioid epidemic and opioid misuse.

Apoptosis induced anticancer potential of aspirin on A549 Carcinoma Cell
Authors: Junaid Abu , Kumar Ajay
Published: May 2022

Recent research has discovered that using aspirin for a long time lowers the long-term risk of certain cancers, particularly colon cancer. However, the mechanism of anti-cancerous activity of aspirin against lung cancer is less studied. A molecular docking strategy was employed to identify the possible targets of aspirin while5-Fluorouracil (5-FU) was used as a positive control against lung cancer cell line A459. The In-silico analysis suggested that Caspase-3, Bax, andBcl-2could be potential targets for aspirin. The estimation of binding energies for these proteins resulted in -5.2, -5.8, and -5.7 Kcal/mol, respectively, which were better than 5FU (-4.8, -4.6, and -4.4, respectively).Trypan blues dye exclusion test exhibited a reduction in cell viability with the increase in Aspirin concentration. The IC50 values of Aspirin were calculated as 2.79 mM by MTT assay. The treatment of A459 cells with aspirin enhanced the levels of apoptotic genes at mRNA as well as at protein levels. The effect on the A549 lung cancer cell line, this study contributes to a better understanding of how Aspirin and 5-FU work in lung cancer.

Authors: Pandey Payal , Kumar Ajay
Published: May 2022

The pathogenicity of the bacteria is increasing at an alarming rate as they have developed several means to overcome the treatments done for their removal. The Biofilm formation is one of that major ways used by the bacteria to increase its sustainability. This biofilm provides rigidity and resistance to the bacteria against the antibiotics. There is a requirement of another approach to treat such pathogen forming this rigid barrier. Nanoparticles have proven to be effective against such type of barrier and have shown to be potent anti bio film agents. The present study aims on developing the selenium nanoparticles using the biological and chemical methods to act against the bio film forming bacteria that is S. aureus and P. aeruginosa. The biofilm forming bacteria were isolated from the sewage water sample on the selective media and further characterized through staining and biochemical test. The selenium nanoparticle was synthesized biologically using Emblica officinalis extract and chemically using ascorbic acid along with sodium selenite in both the cases. The synthesized nanoparticle was characterized by UV-visible spectra and its antibacterial activity was checked through ‘Agar well diffusion’ against the isolated bacteria. The antioxidant property of both nanoparticles was analyzed through FRAP assay.

Published: May 2022

Background: In developing countries, street vended foods continue to expand as an affordable food source which impacts the economy. However, the contamination of these foods leads to the outbreak of foodborne diseases and is considered a significant public health issue in Asian countries. This study assessed the microbial load and heavy metal contents in locally available street foods (shawarma, fruit chaat, and dahi baray) in different locations in Faisalabad city, Punjab province of Pakistan. Methods: A total of 60 food samples from five different locations in Faisalabad city were analyzed for microbial quality (Escherichia coli, Salmonella sp, and Staphylococcus aureus, and total viable count) and heavy metals levels (Zn, Cu, Pb, and Cd). A design was used to conduct questionnaires concerning vendors’ knowledge about food hygiene and sanitary practices. Data obtained were statistically analyzed by using the SPSS 21 Statistical Software. Results: The street foods were highly contaminated with Staphylococcus aureus (1.266×104 cfu g-1), Escherichia coli (0.370×104 cfu g-1), and Salmonella species (0.016×104 cfu g-1). The average heavy metal contamination of lead, zinc, copper, and cadmium were measured at 0.955 mg/kg, 3.712 mg/kg, 0.317 mg/kg, and 1.000 mg/kg, respectively. The survey questionnaire indicated the contamination of water and unhygienic conditions as significant sources of low-quality street foods. Conclusions: The results revealed that mostly the street foods sold in Faisalabad were contaminated with heavy metals and pathogenic bacteria. The unhygienic practices and contaminated water were the main factors for unhealthy street vended foods production. In this regard, food-safety practices, education, and regulations related to safe food production have been recognized as measures for ensuring the quality of vendor foods.

Published: May 2022

Gender and development issues and inclusive education are related to child protection, and these are very prevalent today as the Department of Education recognizes that there may be instances of violence at school due to the challenging situations faced by teachers and other officials inside and outside the school. Teachers face many overlapping obligations and obstacles to children's safety, inclusive environments, and gender and development issues, which creates many difficulties in their daily planning. The teacher's innate strength in dealing with a situation in the broad sense of child protection, as well as its incorporation into learning activities, has several considerations such as gender and development and inclusive education. With that, the researcher assessed the implementation of Gender and Development and Inclusive Learning Practices in the Department of Education in the Bayombong Districts as a basis for Organization Development Intervention. The descriptive research method was used, with a survey questionnaire used to collect data from 26 school heads and 153 teachers from the Bayombong Districts. Frequency and percentage, weighted mean, correlational procedure (f-test) and test of variance (t-test) were employed to analyze the data statistically. Findings revealed that gender and development, as well as inclusive learning practices, were sometimes implemented. When respondents are grouped according to their demographic profile, there is a significant difference in their perception, which is also significantly correlated with the level of implementation in learning practices. As a result, the proposed organization development intervention is expected to address the respondents' problems and challenges in implementing gender and development and inclusive learning practices in the teaching-learning process.

The following paper presents a Computational Fluid Dynamic (CFD) comparative study ofthe effect of side wall and roofs vents openings on canary greenhouse airflow circulation andclimate distribution under different ventilation processes. The investigation was conducted ina one hectare canary greenhouse type, which is the most widespread type in the wholeMediterranean and along the Atlantic coast area of Morocco, especially in souss vally region.The simulations were performed with the commercial code CFD2000 based on the solution ofthe partial differential equations, which describe the flows, and was obtained by discretizingthe space and time and solving the transport equations on the spatial grid as differenceequations, used a finite volume discretization. The standard two equations k-Îµ model wasused to describe the turbulent transport. The influence of external factors such the covertemperature, the wind speed, on the flow was simulated by boundary conditions, these valueswere obtained from experimental results. Simulations were conducted with a fixed windspeed equal 1.05 m/sec, tomato crop rows oriented north-south and the ventilation openingsare continuous and equipped with insects screen type 20/10. Results reveal that ventilationopening arrangements strongly affects the greenhouse wind speed, which can generate aheterogeneous climate, especially during daytime. But in the other hand, results confirm thatthere is no significant effect of the side wall vents opening on canary greenhouse airtemperature and humidity fields.
Spatio-temporal planning simulation of temporary elevators in construction using a game engine
Authors: Wu Keyi , Garcaí de Soto Borja
Published: May 2022

Designing a reasonable and efficient transportation system of temporary elevators from the perspective of spatio-temporal planning is beneficial for the successful completion of construction projects. Specifically, the determination of the service period and floor of temporary elevators and the consideration of the limited availability of time and space should be taken seriously. The spatio-temporal planning of temporary elevators puts forward higher requirements for the display of planning solutions due to the complexity considering both time and space. However, current display ways are generally abstract, low-dimensional, and static, and even when the 4D model is adopted, the display effect of spatio-temporal planning solutions is still limited. This research presents a spatio-temporal planning simulation of temporary elevators in construction using a game engine to address those challenges. The workflow of the spatio-temporal planning simulation divided into configuration and operation planning consists of three steps: 1) import data into the game engine platform, 2) generate the spatio-temporal planning simulation scheme, and 3) conduct the spatio-temporal planning simulation. The results of the experimental test show that the presented spatio-temporal planning simulation way is intuitive and convenient, various planning elements are clearly shown, and corresponding planning information is efficiently conveyed, which can effectively enhance the display effect of spatio-temporal planning solutions.
Bots2ReC - Analysis of Key Findings for the Application Development of Semi-Autonomous Asbestos Removal
Authors: Haschke Tobias , Hüsing Mathias , Corves Burkhard
Published: May 2022

The removal of asbestos from existing buildings is a socially important and challenging renovation process due to the handling of hazardous materials. The EU project Robots to Re-Construction (Bots2ReC) has developed a robotic system for semi-autonomous asbestos removal for apartment buildings. The removal of plaster and tiles and the associated tile adhesive is implemented as a semi-autonomous construction task by mobile manipulators and integrated into the existing construction process. The development is based on a test-driven approach in order to obtain information about the achievable performance and the acceptance of the human operators as early as possible. The identification of the control variables for the respective tools and the embedding in the on-site process flow are named as the main reasons for the test-driven approach. The analysis of selected key findings of the project shows for the developed semantic mapping via mobile robot that a minimal, application-specific data format favours an efficient overall process control via task planning up to execution. In the development of mobile bases for the application, it can be shown that a holonomic drive is preferable to a differential drive due to the partly narrow and angled parts of the building. To carry out the intended processes and to guide the automated power tools, the in-house development of serial manipulators is necessary, since the combination of the required working space with the occurring weight and process forces cannot be solved within the requirements by an industrial manipulator. Finally, the main benefit of this papers contribution is seen in the transferable outcomes to other on-site automation projects.
The Impact of the Covid-19 Pandemic on Multilateral Peace Operations
Authors: van der Lijn Jaïr
Published: May 2022

This paper looks at the direct operational impacts the Covid-19 pandemic has had on multilateral peace operations, and what these meant for mandate implementation. It also surveys the strategic and long-term impacts and how these may impact demand for peace operations. It closes by drawing up recommendations for the future. It finds that mostly peace operations have succeeded in holding on to the achievements they had made before and have prevented regressions, but little progress was made. The direct operational impacts of the Covid-19 crisis on mandate implementation were largely mission and time specific, and differed per mandate task. Although, strategically the Covid-19 pandemic may not have significantly changed the short-term global conflict map, its long-term negative impacts may increase the demand for peace operations.
Tourism Businesses’ Perceptions on Sustainable Practices and Barriers in Coastal North Carolina, USA
Authors: Hao Huili , Hill Jeffery M
Published: May 2022

The objective of this study was to investigate tourism business owners’ and operators’ perceptions of sustainable practices which would facilitate the success of their tourism businesses in the long term, as well as their perception of barriers to implementation of these sustainable practices. The study area was the North Carolina coastal counties where tourism is a major economic driver. Data were collected from 90 tourism businesses in 20 coastal counties in North Carolina. The study profiled the tourism business segments using a factor-cluster grouping approach that identified tourism business clusters. Three clusters were identified representing different levels of tourism business owners’ and operators’ perceptions of sustainable practices: Advocators, Accepters, and Anticipators. Comparative analyses were then conducted among these three groups to profile them based upon perceived barriers that prevent them from implementing sustainable practices. The results showed that prevalent barriers to implementing sustainable techniques were lack of funds, lack of financial incentives, complexity of implementation and cost. These findings could provide informed guidance to tourism entities when considering their sustainable actions, as well as provide data which may influence the role that state tourism officials play in advocating best practices that maintain and present tourism products in a sustainable manner.

In order to achieve this objective, a survey was carried out on nearly 30 farms: 13 are in the irrigated lands and 17 are in dry areas. As a first step, we proceeded through a socio-economic, technical and environmental assessment in order to determine the characteristics of each type of farms. As a second part, we tried to identify the strengths, weaknesses, opportunities and threats specific to the olive sector in this arid region, through SWOT method. The assessment shows that the irrigated farms were the object of modernization process, whose owners are really investors, aiming a rapid profitability by this farming activity. The farms are characterized by a high density of olive tree plantations and the stability of yields. Thus, they represent a source of employment in the region. On the other side, dry olive farms have a classic production system and low yields, generating not only a problem of profitability, but also of the viability of these farms, which explains the abandonment of these lands.

Purpose: Purpose of this study was to elucidate the differences in sprint performance between two different conditions in the 60 m dash: subjects ran alone (Alone Condition: AC) or two runners competed side-by-side (Competitive Condition: CC). Methods: Subjects were twenty-six male university sprinters. They were asked to perform two 60 m dash, the AC and CC, with maximal effort from crouching start. Running spatiotemporal variables were obtained from video images taken with two digital high-speed cameras. Results: Running speed (AC: 9.34 ± 0.45 ms-1 vs CC: 9.40 ± 0.43 ms-1, p = .011) and step length (AC: 2.04 ± 0.12 m vs CC: 2.06 ± 0.10 m, p = .021) in the maximal speed section (30-60m) were significantly increased in the CC. However, there was no significant difference in step frequency (AC: 4.58 ± 0.26 Hz vs CC: 4.57 ± 0.27 Hz, p = .595). There was no significant difference in any variables in the acceleration section (0-30m). Conclusion: These results indicate that running with a competitor improves running speed with increasing step length in the maximal speed section but does not affect performance in the acceleration section. We concluded that competition improves sprint performances in the maximal speed section.
