This research explores the of effective curriculum design for higher-ed in preparing agricultural education graduates for Nigeria’s labor market. The continuing professional education program planning theory serves as the framework guiding this study. The study involves a phenomenological inquiry into the conscientious meaning experience of the faculty and alumni in an agricultural education department. A purposeful sampling method of 14 participants (four professors and 10 alumni) was used to select participants since the study relied on individuals close to the phenomenon. Data was collected using a standardized open-ended questionnaire and the Department’s handbook. Three themes emerged: The Department's curriculum design/development; Stakeholder’s consultation; and Principles considered while designing the curriculum. Recommendations were made for the Department to continuously review and update the curriculum to reflect the current needs of the industry and students. Lastly, the current study was recommended to be replicated in other main agricultural institutions in Nigeria.

Published: May 2022

Atualmente, temos visto um aumento na disponibilidade de meios eletrônicos no ambiente domiciliar, onde novas tecnologias de mídia eletrônica (TV, computadores, wireless, banda larga, equipamentos multifuncionais e jogos de video-game interativos) são parte integrante do domicílio e com utilização diária pelos indivíduos, o que implica na redução das oportunidades de atividades físicas em casa e maior tempo em comportamentos sedentários, reduzindo o gasto energético total. Desta forma, o objetivo do presente ensaio é apresentar, em reflexão os fatores associados a prática de atividade física ao longo da vida, frente a diferentes determinantes da atividade física. Tratou-se de um ensaio reflexivo que nos proporcionou uma ampla análise dos comportamentos sedentários. Dessa forma, diariamente as crianças são expostas a múltiplos equipamentos que podem estimular comportamentos sedentários, ou a atividade física, sendo que o ambiente da casa provavelmente influencie nessa escolha. Teorias sugerem que para definir entre comportamento sedentário ou ativo depende em parte, da facilidade de acesso a atividade física ou sedentárias na casa e vizinhança. Em relação as diferentes fases da vida, observamos maior quantidade e utilização de equipamentos para atividade física na infância, exceto skate e equipamentos de “fitness” do que em adolescentes e adultos. Nossos resultados parecem contribuir para o desenvolvimento de programas de promoção da saúde em diferentes fases da nossa vida necessitando desta forma um maior entendimento a respeito da transitoriedade ao longo das fases da vida.

On the Jewish Havruta Learning Method
Authors: Xiaodong Yu
Published: May 2022

China pays attention to test-oriented education and emphasizes the role of a teacher as a knowledge distributor. Thus, the classroom teaching is mainly based on the injection of knowledge, while our public education is lacking in setting general education courses for Arts and Humanities. Taking competitive advancement as the core, our students complete the independent learning model in the traditionally competitive way and emphasize the accumulation of personal knowledge to increase personal competitiveness. This article studies the Jewish learning method, that is, the Havruta learning method theory. This article starts from investigating the initial application scope of the Havruta learning method. Then it gives the definition, constituent elements, deployment and implementation of the Havruta learning method. Meanwhile, it demonstrates how to set in the process of teaching to make use of the teaching method. According to the research, we suggest that it is rather necessary for us to introduce the Havruta learning method in order to promote the students' moral education, cultivate their wisdom, and establish the way of critical thinking, especially under the current test-oriented education for schools that uses competitive individual learning as a means of entering a higher education, extracurricular tutoring classes that focus on strengthening test-oriented classroom knowledge, and utilitarian families that blindly pursue scores.
The Diagnosis and Prevention of Fluorosis in Humans
Authors: Choubisa Shanti Lal
Published: May 2022

Chronic fluoride intoxication in the form of fluorosis is a worldwide health problem and endemic at least in 25 countries. The principal cause of fluorosis in humans is the prolonged exposure of fluoride through drinking of fluoridated water. However, industrial fluoride emission and fluoride containing foods are also potential sources of fluoride exposures for the genesis of fluorosis. As per guidelines of the World Health Organization (WHO) fluoride content in the drinking water should not be higher than 1.5 mg/L (ppm). Above this limit of fluoride in drinking water, it becomes toxic and injurious for human health and causes diverse deformities in teeth and bones. In humans, basically three forms of fluorosis namely dental, skeletal and non-skeletal fluorosis have been recognised. The diagnosis of fluoride intoxication (fluorosis) in humans is made on the basis of history, clinical or pathognomonic signs and testing of biological samples. The current status of endemic fluorosis could be assessed by estimation of fluoride in the blood serum and urine. The presence of dental mottling and calcification of interosseous membrane on a forearm radiograph may be helpful in the diagnosis of dental and skeletal fluorosis, respectively. For the prevention of fluorosis, fluoride free drinking water and food items, diet having ample amount of nutrients, general awakening in people and collective efforts are important and highly needed. This editorial will be useful for researchers and health workers in the diagnosis and prevention of fluorosis in humans, respectively.
Molecules Absorption Prediction Using Support Vector, Adaboost, Random Forest and Decision Tree Classification
Authors: Suprapto Suprapto , Nimah Yatim Lailun
Published: May 2022

Classification is supervised machine learning applicable to predict chemicals based on their properties. The chemical properties are derived from its structural and functional groups. Many molecular descriptors have been developed, one of which, was pharmacophore. Pharmacophore is a quantitative measure of molecules in their application as a pharmaceutical ingredient. The training datasets were 59 molecules categorized on their adsorption properties. The classification was carried out to divide the training set into their adsorption class using their pharmacophores. The prediction of enolic curcumin and its degradation product was used to verify the trueness of classification methods based on their pharmacophores. Curcumin and its degradation product were used because there were many studies carried out about curcumin and its pharmaceutical effect.
New Zero-Velocity Detector for Low-Cost Inertial Pedestrian Navigation
Authors: Muhammad Syahmi Hamdan  , Khairi Abdulrahim
Published: May 2022

A new Zero Velocity Interval (ZVI) detector is proposed and investigated in this article to augment the computation of a pedestrian’s position. In a low-cost pedestrian navigation system, the position of a pedestrian can be computed by using inertial navigation algorithms. The low-cost pedestrian navigation system employs an inertial measurement unit (IMU) comprised of accelerometer and gyroscope sensors to record acceleration and attitude rate. These measurements, when integrated mathematically, yield velocity and position. Similarly, attitude rate changes to attitude. The algorithm will then be able to figure out the changes in pedestrian position with the proper attitude. However, due to its low-cost nature, these sensors are built in such a way that their measurements are easily corrupted by noise, and once integrated mathematically, the measurement error grows exponentially. Zero Velocity Update (ZUPT) algorithm is frequently used to limit these errors. It works by detecting the ZVI that occur when the foot is on the ground. Assuming that the foot on the ground should have zero velocity, any remaining velocity measurements detected during this period are considered an error and are fed back to the navigation algorithm for correction. To detect the ZVI, a few commonly used detectors, namely Angular Rate Energy (ARE), Acceleration Moving Variance (MV), Acceleration Magnitude (MAG), and Generalized Likehood Ratio Test (GLRT) were revisited. These detectors were tested with real-world datasets of walking pedestrians. Then, a new detector, the Angular Rate Moving Variance (ARMV) detector, is proposed, and its performance is compared to that of the existing detectors.
DEEP NEURAL NETWORK BASED DATA-DRIVEN VIRTUAL SENSOR IN VEHICLE SEMI-ACTIVE SUSPENSION REAL-TIME CONTROL
Authors: Kojis Paulius , Šabanovič Eldar , Skrickij Viktor
Published: May 2022

This research presents a data-driven Neural Network (NN)-based Virtual Sensor (VS) that estimates vehicles’ Unsprung Mass (UM) vertical velocity in real-time. UM vertical velocity is an input parameter used to control a vehicle’s semi-active suspension. The extensive simulation-based dataset covering 95 scenarios was created and used to obtain training, validation and testing data for Deep Neural Network (DNN). The simulations have been performed with an experimentally validated full vehicle model using software for advanced vehicle dynamics simulation. VS was developed and tested, taking into account the Root Mean Square (RMS) of Sprung Mass (SM) acceleration as a comfort metric. The RMS was calculated for two cases: using actual UM velocity and estimations from the VS as input to the suspension controller. The comparison shows that RMS change is less than the difference threshold that vehicle occupants could perceive. The achieved result indicates the great potential of using the proposed VS in place of the physical sensor in vehicles.
The Long-term Spectroscopic and Photometric Behavior of the Carbon Star RS Cygni
Authors: Cadmus Robert R.
Published: May 2022

RS Cygni is a semiregular variable carbon star that has a distinctive light curve. Twenty-one years of optical spectroscopic and photometric observations of this star made at Grinnell College have been used not only to produce a comprehensive survey of the behavior of this star but also to compare these two sets of data. A number of spectral features vary in strength with the cycle of the star and some, but not all, of this variation is correlated with the dips that often occur near the maxima of the light curve. In particular, the strengths of the Balmer emission lines often have two peaks per cycle. Such correlation might be consistent with a mechanism for producing the dips, such as dust formation, that reduces the brightness in a way that does not involve rapid changes in photospheric characteristics. The large amount of data and the precision of the photometry presented give an unusually detailed view of how the light of RS Cyg varies over time.

Dynamical models are crucial for uncovering the internal dynamics of galaxies; however, most of the results to date assume axisymmetry, which is not representative of a significant fraction of massive galaxies. Here, we build triaxial Schwarzschild orbit-superposition models of galaxies taken from the SAMI Galaxy Survey, in order to reconstruct their inner orbital structure and mass distribution. The sample consists of 161 passive galaxies with total stellar masses in the range 109.5–1012

The discovery of the electromagnetic counterpart to the binary neutron star (NS) merger GW170817 has opened the era of gravitational-wave multimessenger astronomy. Rapid identification of the optical/infrared kilonova enabled a precise localization of the source, which paved the way to deep multiwavelength follow-up and its myriad of related science results. Fully exploiting this new territory of exploration requires the acquisition of electromagnetic data from samples of NS mergers and other gravitational-wave sources. After GW170817, the frontier is now to map the diversity of kilonova properties and provide more stringent constraints on the Hubble constant, and enable new tests of fundamental physics. The Vera C. Rubin Observatory’s Legacy Survey of Space and Time can play a key role in this field in the 2020s, when an improved network of gravitational-wave detectors is expected to reach a sensitivity that will enable the discovery of a high rate of merger events involving NSs (∼tens per year) out to distances of several hundred megaparsecs. We design comprehensive target-of-opportunity observing strategies for follow-up of gravitational-wave triggers that will make the Rubin Observatory the premier instrument for discovery and early characterization of NS and other compact-object mergers, and yet unknown classes of gravitational-wave events.

Biogeographic assessment of Gorgonian associated bacteria with antipathogenic Urinary Tract Infections (UTIs) in Karimunjawa Marine National Park, Java Sea, Indonesia
Authors: Sabdono Agus , Lestari Endang Sri , Sibero Mada T.
Published: May 2022

Gorgonian corals of Karimunjawa are impacted by anthropogenic activities, such as increasing high mariculture intensity with consequent eutrophication, overfishing, tourism, sewage, and other pollutant discharge, which result in changes in the microbial community structure. In this study, bacterial communities associated with six species of gorgonian, Viminella sp., Ellisella sp., Antipathes sp., Melithaea sp., Astrogorgia sp, and Junceella sp. from both the Marine Protected Area (MPA) and non-Marine Protected Area (non-MPA) zones were screened for their antipathogenic potential against Urinary Tract Infections (UTIs) pathogens. The selected bacterial isolates were identified and compared for their abundance and diversity between the two zones. 156  bacterial strains were assayed for their prospective antipathogenic compounds against seven UTI pathogens, including Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Streptococcus saptophyticus, Acinetobacter baumannii, Klebsiella pneumonia, Candida albicans. The result showed that 17 of  92 (18.48%) and 6 of 64 (9.37 %) bacterial isolates from MPA and non-MPA, respectively, exhibited antimicrobial activity in at least one UTIs pathogens. Analyzing the gene of 16S rRNA discovered that the 17 isolates of MPA were associated with phyla Actinobacteria, Firmicutes, and Proteobacteria, including Streptomyces zhaozhoue, Nocardiopsis salina, Micrococcus endophyticus, Brevibacterium casei, Micrococcus yunnanensis, Saccharopolyspora coralli, Bacillus paramycoides, Virgibacillus salarius, Oceanobacillus iheyensis, Vibrio alginolyticus. In contrast, only six selected isolates of non-MPA were associated with phyla Actinobacteria and Proteobacteria, including  Nocardiopsis salina, Micrococcus yunnanensis, and Acinetobacter soli. The diversity index (H'), species richness (S), and relative abundance of the MPA zone were higher than that of non-MPA. These results demonstrated that gorgonian octocoral species in the MPA region harbor varied bacteria and propose that many gorgonian-associated bacteria have the prospective for advancing broad-spectrum antibiotics.
Studying local species assemblages of salt-affected vegetation for monitoring Natura 2000 habitats

Published: May 2022

This study aims to characterize saline habitats of the Tuscan coast based on the Natura 2000 Habitats Directive ﻿92/43/ECC. These habitats include Atlantic salt meadows (1330), Mediterranean salt meadows (1410) Mediterranean and thermo-Atlantic halophilous scrubs (1420), and Mediterranean salt steppes (1510). We compiled vegetation data from a total of 418 plots carried out during our own fieldwork (N = 157) and published scientific literature (N = 261). We performed a Linear Discriminant Analysis to associate species to habitats and used the phi coefficient of association to identify diagnostic species of each habitat. For each habitat, we provide a regional syntaxonomic framework, constant species, cover coefficients, diagnostic species (phi) and “typical species”. We identified groups of species, that we called “local assembly of typical species”, composed by species with a phi coefficient > 20 and/or a cover coefficient > 50 that can be used to identify the habitats and to monitor their conservation status at the local level. This study revealed differences in the “local assembly of typical species” among habitats, characterized by fewer species in habitats 1420 and 1510, and many species in habitats 1410 and 1310. Our results showed that the habitat 1510 was recognizable only for the high cover value of Limonium narbonense and, at least in Tuscany, its syntaxonomic attribution to the order Limonietalia is uncertain. We tested this approach only for a few habitats, but a broader applicability based on other habitats is desirable.

Well-posedness of an inverse problem for two- and three-dimensional convective Brinkman-Forchheimer equations with the final overdetermination
Authors: Kumar Pardeep , Mohan Manil T.
Published: May 2022

In this article, we study an inverse problem for the following convective Brinkman-Forchheimer (CBF) equations:

   \begin{document}$ \begin{align*} \boldsymbol{u}_t-\mu \Delta\boldsymbol{u}+(\boldsymbol{u}\cdot\nabla)\boldsymbol{u}+\alpha\boldsymbol{u}+\beta|\boldsymbol{u}|^{r-1}\boldsymbol{u}+\nabla p = \boldsymbol{F}: = \boldsymbol{f} g, \ \ \ \nabla\cdot\boldsymbol{u} = 0, \end{align*} $\end{document}

in bounded domains \begin{document}$ \Omega\subset\mathbb{R}^d $\end{document} (\begin{document}$ d = 2, 3 $\end{document}) with smooth boundary, where \begin{document}$ \alpha, \beta, \mu>0 $\end{document} and \begin{document}$ r\in[1, \infty) $\end{document}. The CBF equations describe the motion of incompressible fluid flows in a saturated porous medium. The inverse problem under our consideration consists of reconstructing the vector-valued velocity function \begin{document}$ \boldsymbol{u} $\end{document}, the pressure gradient \begin{document}$ \nabla p $\end{document} and the vector-valued function \begin{document}$ \boldsymbol{f} $\end{document}. We prove the well-posedness result (existence, uniqueness and stability) of an inverse problem for 2D and 3D CBF equations with the final overdetermination condition using Schauder's fixed point theorem for arbitrary smooth initial data. The well-posedness results hold for \begin{document}$ r\geq 1 $\end{document} in two dimensions and for \begin{document}$ r \geq 3 $\end{document} in three dimensions. The global solvability results available in the literature helped us to obtain the uniqueness and stability results for the model with fast growing nonlinearities.

Published: May 2022

In this paper we use the topological degree and the fountain theorem to study the existence of weak solutions for a fractional $ p $-Laplacian equation in a bounded domain. For the nonlinearity $ f $, we consider two situations: (1) the non-resonance case where $ f $ is $ (p-1) $-asymptotically linear at infinity; (2) the resonance case where $ f $ satisfies the Landesman-Lazer type condition.
Éditorial : Nouvelles questions ethniques
Authors: Raulin Anne , Crenn Chantal
Published: May 2022

La question ethnique a toujours été polémique. Dans les années 1980, certains anthropologues ont estimé devoir s’en détourner afin de créer une rupture avec des représentations perçues comme liées à la colonisation. Dans les dernières décennies, nombre de chercheurs ont complexifié son approche théorique, et il importe de faire le point en relation avec les nouvelles conditions historiques, postcoloniales et postsocialistes, la généralisation du marché mondial et celle de la circulation des personnes et des biens, ainsi qu’avec le renforcement du phénomène diasporique. Les contributions à ce dossier montrent que, loin de s’apparenter à un archaïsme, les appartenances ethniques manifestent une réelle capacité d’adaptation dans un contexte toujours dominé par les entités nationales. L’identification ethnique, une des modalités de la perception de l’altérité, ne saurait cependant être limitée aux minorités. Ce dossier donne à connaître les points de vue de l’intérieur de ces appartenances à partir de terrains ethnographiques diversifiés : migrations entre Sénégal et France, marchandisation du « mariage marocain », pratique d’un islam mahorais, diaspora asiatique à Paris, soins ethnicisés à l’hôpital. Il apporte aussi de nouvelles approches théoriques en ouvrant la « situation ethnique » aux dynamiques de globalisation, ou en la différenciant des problématiques liées au racisme et aux discriminations

Comment les rituels du pays d’origine se transforment en marchandise ? Cet article entend réfléchir aux liens entre appartenance, consommation et fabrique de l’entrepreneur·e en problématisant le recours aux catégories ethniques en sciences sociales. Plus précisément, il montre comment la relégation sociale et urbaine des descendant·e·s d’immigré·e·s — d’origine marocaine en France — peut servir de levier pour une ascension socioéconomique à travers les économies festives. Par le biais d’une enquête ethnographique à Avignon, l’article examine de nouvelles figures du travail autonome dans le monde du « mariage marocain » en France et rattache les stratégies de profitabilité propres au capitalisme à divers « arrangements » avec les esthétismes de la culture d’origine. L’article se conclut sur une critique du paradigme de l’ethnicité en faisant valoir l’importance des études des styles de vie pour comprendre comment ceux-ci marquent les sociétés européennes postmigratoires.
Le rôle de l’ethnicité dans les associations culturelles de migrants. Le cas des Sereer (Sénégal) de Dakar et d’Île-de-France
Authors: Ndour Rébecca
Published: May 2022

Croyance subjective en des origines communes dans de nombreuses parties du monde, l’ethnicité suscite souvent chez ceux qui s’en réclament comme chez ceux qui la rejettent l’idée d’une totalité d’être. Avec les migrations, comment est-ce que cette croyance se perpétue à travers le temps et les espaces ? Cet article traite de cette question à travers l’exemple d’associations de migrants Sereer à Dakar et en Île-de-France rencontrées entre 2012 et 2014. L’observation montre que les associations de migrants, en quête d’intégration sociale dans leurs nouvelles zones d’installation, mobilisent la même ethnicité, mais en s’arrangeant avec les exigences de leur cadre national et les propriétés sociales des membres associatifs, pour valoriser des éléments de l’ethnicité en cohérence avec l’objectif d’intégration sociale. Rendue saillante ou voilée, l’ethnicité se révèle une dimension parmi d’autres de l’expérience sociale, dépendante d’elle et la transformant en même temps.
Assessment of primary healthcare accessibility and inequality in north-eastern Kazakhstan
Authors: Shaltynov Askhat , Rocha Jorge , Jamedinova Ulzhan , Myssayev Ayan
Published: May 2022

Out of the many aspects of health care, the concept of physical accessibility is a priority that not only encompasses availability of health care resources, but also requires that they are easily accessible for all. To assess this factor as expressed in terms of the number of available physicians in the north-eastern part of Kazakhstan, we used the enhanced two-step float catchment area in a geographic information system approach. The Gini index and the Lorentz curve were used to evaluate the economic inequality within this region. Based on the data obtained, we developed models to increase the availability of health care considering allocation of additional primary health care resources. A low to zero index was found to be typical for most rural settlements, which currently make up less than 15% of the total population. We also identified a correlation between the index of accessibility and that of inequality, which indicates that areas with high accessibility show a more equitable distribution of resources. The developed location/ allocation models of additional primary health care resources can be useful in implementing government initiatives to improve the availability of primary health care in rural areas.

Background

Monoclonal protein detection and characterization is integral component of myeloma workup and is at times used as the first step toward diagnosis. Costs of these tests are major concern in developing countries.

Recent studies have emphasized on the prognostic importance of risk stratification with cytogenetic in patients with myeloma.

Aims

We intend to analyze additional information obtained by two costly tests, namely, serum free light chain assay (sFLC) and fluorescent in situ hybridization (FISH), for high-risk cytogenetic abnormalities during baseline workup of patients with myeloma and their necessity.

Patients and methods

We retrospectively analyzed laboratory data of 130 patients with myeloma enrolled at our institute between years 2016 and 2019. Subset analyses of 71 patients who underwent all three tests, namely, serum protein electrophoresis (SPEP), immunofixation electrophoresis (IFE), and sFLC for monoclonal protein detection, were done.

Patterns of cytogenetic abnormalities were noted in 70 patients undergoing FISH testing for high-risk cytogenetic abnormalities and serum lactate dehydrogenase (LDH) level. International staging system (ISS) and revised international staging system (RISS) categories were compared among this group of patients.

Statistical analysis used

A proportion test was used.

Results

SPEP detected and quantified M protein in 55 (77.4%) patients. IFE detected M protein in 68 (95.7%) patients and typing was done. sFLC ratio was abnormal in 66 (92.6%) patients. IFE and sFLC were more sensitive in detecting monoclonal protein as compared with SPEP (P=0.001 and 0.009, respectively) at diagnosis.

In 70 patients with FISH and LDH results available, seven (10%) patients had high-risk karyotype on FISH, and LDH was raised in five (7.1%). Based on these results, three (4.2%) patients who were ISS stage I were upgraded to RISS stage II and 21 (30%) ISS III patients were downgraded to RISS II category, thereby helping in 34.2% patients for accurate prognostication.

Conclusion

In resource-constrained setting, using sFLC sequentially after SPEP is noninformative, but UPEP/IFE shows M band, which can be a viable approach at diagnosis. For better prognostication, FISH for high-risk karyotypic abnormalities is required.

Published: May 2022

Context

Acute leukemia (AL) is the commonest hematological malignancy in childhood. The cause is largely multifactorial and unknown, with exogenous and endogenous factors interacting with genetic susceptibility. Its incidence is on the rise globally including developing countries like Nigeria. Although the prognosis in developed countries has improved, poor outcomes are still the norm in resource-poor areas.

Aims

This review was undertaken to document the sociodemographic characteristics, management challenges, and outcomes of leukemia in an African tertiary care setting.

Settings and design

The study was a retrospective review of patients managed for AL over a 30-month period.

Patients and methods

This is a retrospective review of clinical case notes of children admitted with diagnosis of AL.

Results

A total of 31 children had morphological diagnosis of AL; half of them had acute lymphoblastic leukemia, a third acute myeloid leukemia, and one-sixth bilineal leukemia, respectively. Most patients were from low socioeconomic status. All patients sought alternative or complimentary care, and source of health care expenditure was out of pocket. The mean duration of symptoms was 12.9±10.3, time to diagnosis in our hospital was 3.7±2.1 days, and duration of hospital stay was 36.7±43.4 days. The mean packed cell volume, white blood cell, and platelet counts were 14.2±5.3, 37.9±30.2×109/l, and 45.4±54.3×109/l, respectively. Only four patients attained remission of the 15 (48.4%) who received chemotherapy. The mortality was 11 (35.5%) cases, with eight cases being owing to hemorrhage from severe thrombocytopenia.

Conclusions

The study shows delay in time from symptoms to presentation, time to diagnosis, and commencement of chemotherapy with associated poor outcomes. All patients sought alternative and/or complementary interventions before presentation.

BACKGROUND:

Workplace bullying (WPB) is any sort of repeated and unjustified verbal, sexual, or physical intimidation that a person is exposed to by a group or another person in the workplace. In healthcare environments, practitioners are occasionally victims of WPB incidents. Bullying in surgical environments is an important issue that needs attention as it could affect patient care either directly or indirectly. The objective of this study was to assess the prevalence of bullying in surgical environments in multiple regions in Saudi Arabia.

MATERIALS AND METHODS:

This cross-sectional study was conducted among surgeons, trainees, interns, nurses, and students in surgical specialties in multiple Saudi regions. The survey was designed by Survey Monkey and posted online. The data were analyzed through SPSS Version-21 by computing descriptive statistics as frequency and percentages with graph construction.

RESULTS:

About two-thirds (65.2%) of the 788 study participants were male and were between the age of 20 and 29 years (67.8%). Consultants came first as perpetrators of bullying in the past 12 months (44.3%) and residents and interns were the major victims. The NAQ-R score ranged from 22.00 to 110.00, with a mean score of 42.47 (SD=17.9). Statistically significant association was found between mean NAQ-R score and age (P = 0.007), specialty (P = 0.002), and position (P < 0.001).

CONCLUSION:

WPB is a pervasive problem in surgical environments in multiple regions of Saudi Arabia. Consultants and specialists are the primary offenders in bullying, which makes the hospital an environment for bullying behaviors.

BACKGROUND:

Video games have become popular in the last few decades, resulting in an increase in reported negative consequences. This study aimed to assess the prevalence of internet gaming disorder (IGD), its association with gaming behavior, depression, and anxiety in male high school students.

MATERIALS AND METHODS:

This cross-sectional study involved male high school students in Dammam. Schools were selected using stratified random sampling, and data were collected using a self-administered questionnaire. Data analyzed using SPSS v23.0; the initial analysis included descriptive statistics. Continuous and ordinal variables were compared using t-test or Mann–Whitney U test, and ANOVA or Kruskal–Wallis test, as appropriate; Chi-square test was used for categorical variables. Spearman correlation coefficient was calculated to determine the correlation between IGD score and depression and anxiety scores.

RESULTS:

A total of 726 high school gamers were involved, 87% of whom were Saudi, with a mean age of 16.92 years and 45% were from public schools. The mean IGD score was 18.12, and the prevalence of IGD was 21.85%. Students who spent ≥4 h/day on weekdays or ≥6 h/day at weekends on videogames and gamers who spent ≥200 Saudi Riyals per month on gaming had significantly higher mean IGD scores (P < 0.001). Gamers who used PC/laptop for gaming had significantly higher IGD scores compared to those who used other devices (P = 0.002). Action, fight, open-world games, and games with violence were associated with significantly higher IGD scores. Among students with IGD, 21.7% had moderately severe/severe depression and 11.4% had severe anxiety.

CONCLUSION:

IGD is a concerning psychiatric disorder in male high school students. It is associated with certain gaming behavior and other mental problems. We recommend future larger-scale research that includes females as well.
On the sharp interface limit of a phase field model for near spherical two phase biomembranes
Authors: Elliott Charles M. , Hatcher Luke , Stinner Björn
Published: May 2022

We consider sharp interface asymptotics for a phase field model motivated by lipid raft formation on near spherical biomembranes involving a coupling between the local mean curvature and the local composition. A reduced diffuse interface energy depending only on the membrane composition is introduced and a

\Gamma

-limit is derived. It is shown that the Euler–Lagrange equations for the limiting functional and the sharp interface energy coincide. Finally, we consider a system of gradient flow equations with conserved Allen–Cahn dynamics for the phase field model. Performing a formal asymptotic analysis, we obtain a system of gradient flow equations for the sharp interface energy coupling geodesic curvature flow for the phase interface to a fourth order PDE free boundary problem for the surface deformation.
