Introduction
Work-related musculoskeletal disorders (WRMSDs) are the leading cause of disability worldwide. Shopkeepers are prone to developing work-related musculoskeletal disorders, but they are largely overlooked in research and policy actions, particularly in developing countries. So far, there is a lack of data on the magnitude and factors influencing work-related musculoskeletal disorders among shopkeepers in Ethiopia. Therefore, the current study aimed to explore the prevalence and risk factors of work-related musculoskeletal disorders among shopkeepers in Gondar City, Ethiopia.

Methods
A workplace-based cross-sectional study was conducted from July to August 2022, in Gondar city, Northwest Ethiopia. A multistage sampling technique was used to select 625 shopkeepers. The data were collected using an interviewer-administered standardized Nordic Musculoskeletal Questionnaire. Analysis was made using Stata version 14. Factors associated with the prevalence of work-related musculoskeletal disorders were identified using the multivariable Poisson regression model. The adjusted prevalence ratio with 95% confidence intervals (CIs) and p-value < 0.05 were applied to establish the significance of associations.

Results
The overall prevalence of work-related musculoskeletal disorders among shopkeepers in the past 12 months was found to be 81.1% (N = 507). The most frequently affected body part was the lower back (46.6%), followed by the upper back (43.8%) and shoulder (35.4%). Being female (p = 0.043), being in the age group of ≥40 years (p = 0.028), being overweight (p = 0.035), experiencing job stress (p = 0.006) and prolonged sitting (p = 0.045) were significant factors for the prevalence of work-related musculoskeletal disorders among shopkeepers.

Conclusion
This study revealed that shopkeepers face an alarmingly high prevalence of work-related musculoskeletal disorders. Female, older, overweight, stressed and shopkeepers who sit in the same position for long periods of time were identified as particularly vulnerable groups. These findings call for the urgent development and implementation of preventive measures, including ergonomic adjustments, education and training programs, stress management techniques and the promotion of physical activity, to protect this vulnerable workforce from the debilitating effects of work-related musculoskeletal disorders and to ensure their long-term health and well-being.

This work aims to investigate the correlation between the bulk modulus as well as the microhardness and the lattice parameter of several cubic zinc-blende III-V semiconductors. Our study shows that both the bulk modulus and the microhardness correlate no-linearly with the lattice parameter of III-V binary compounds. The best fits were obtained using the Gaussian model, the coefficients of the correlation were found at around 0.993 for the bulk modulus, and 0.996 for the microhardness, respectively. Our expressions perhaps used with high accurate to predict the bulk modulus and the microhardness of other binary compounds and ternary semiconductor alloys.Â Â Â
ANALYSIS OF CREATIVE THINKING SKILLS ON THE PHYTHAGOREAN THEOREM MATERIAL IN TERMS OF SELF-CONFIDENCE
Authors: Alyani Fitri , Mercury Aminanti Narin Ledy 
Published: March 2024

The purpose of this study is to describe the ability of students' creative thinking processes on the Pythagorean theorem material which is reviewed based on self-confidence. The subjects of this study were Junior High School students at grade VIII in Jakarta, as many as 120 students. This study uses a qualitative method with a descriptive approach. The stages carried out are: filling out a self-confidence questionnaire, testing creative thinking skills with Pythagoras theorem questions, interviews, analyzing data, drawing conclusions. Based on the results obtained, the high self-confidence classification of students affects the students' high mathematical creative thinking skills as well. Classification of self-confidence is moderate, then the students' mathematical creative thinking ability is quite good. Conversely, if the classification of a student's self-confidence is low, then a student’s mathematical creative thinking skills is also low.

Published: March 2024

Abstract
Concrete is considered one of the greatest innovations in the construction industry since it has significant applications in the construction field. The main limitation of concrete is the low flexural and tensile strength, especially for concrete tiles used for floors and roofs. Therefore, this study aims to enhance the behavior of concrete tiles by using both nano-papyrus (NP) and carbon fibers (CF). Eleven different concrete mixtures with different content of NP and CF were prepared using various models, and the percentage of NP content ranged from 1.5 to 7.5%, while the percentage of CF content ranged from 0.2 to 1%; flexural strength and water absorption tests were also conducted. It was found that employing NP enhanced the flexural strength of concrete tile by up to 48%, whereas using both NP and CF optimized the flexural strength by up to 57%. Also, the surface and total absorption rates decreased by up to 47.1 and 52.6%, respectively.

Abstract
Fiedler, MJ, Triplett, NT, Hamilton, KC, Needle, AR, and van Werkhoven, H. The effect of different weight plate widths (bumper vs. standard) on the biomechanics of the bench press. J Strength Cond Res 38(4): e143–e149, 2024—Anecdotal evidence suggests that bumper plates impact lifts in powerlifting and weightlifting differently than standard cast iron plates, but whether biomechanical differences exist between lifts using bumper versus standard plates has not been investigated. Eleven resistance-trained subjects performed the bench press at 70, 80, and 90% of their 1 repetition maximum (1RM) while being blinded to whether they were lifting with bumper or standard plates. Motion data were captured by an 8-camera motion capture system, and electromyography (EMG) data were recorded for the anterior deltoid, pectoralis major, and triceps brachii. Repeated-measures analysis of variances showed a significant main weight effect for time under tension (p < 0.001), total work (p < 0.001), and muscle activity through EMG (across all muscles; p < 0.001) and a significant weight × joint interaction effect for average joint moment (p < 0.001) and peak joint moment (p < 0.001). However, there were no significant differences observed between the different weight plates for any of the measures. The main finding of the study suggests that there are no biomechanical differences between using bumper plates compared with standard plates during the bench press lift.

Abstract
Nunes, JP, Blazevich, AJ, Schoenfeld, BJ, Kassiano, W, Costa, BDV, Ribeiro, AS, Nakamura, M, Nosaka, K, and Cyrino, ES. Determining changes in muscle size and architecture after exercise training: One site does not fit all. J Strength Cond Res 38(4): 787–790, 2024—Different methods can be used to assess muscle hypertrophy, but the effects of training on regional changes in muscle size can be detected only using direct muscle measurements such as muscle thickness, cross-sectional area, or volume. Importantly, muscle size increases vary across regions within and between muscles after resistance training programs (i.e., heterogeneous, or nonuniform, muscle hypertrophy). Muscle architectural changes, including fascicle length and pennation angle, after resistance and stretch training programs are also region-specific. In this paper, we show that the literature indicates that a single-site measure of muscle shape does not properly capture the effects achieved after exercise training interventions and that conclusions concerning the magnitude of muscle adaptations can vary substantially depending on the muscle site to be examined. Thus, we propose that measurements of muscle size and architecture should be completed at multiple sites across regions between the agonist muscles within a muscle group and along the length of the muscles to provide an adequate picture of training effects.
Serotonin signaling in hippocampus during initial cocaine abstinence drives persistent drug seeking
Authors: Kohtz Amy S. , Zhao Joshua , Aston-Jones Gary 
Published: March 2024

The initiation of abstinence after chronic drug self-administration is a stressful event. Cocaine-seeking behavior on the first day of the absence of expected drug (extinction day 1, ED1) is reduced by blocking 5-HT signaling in dorsal hippocampus CA1 (CA1) in both male and female rats. We hypothesized that the experience of ED1 can substantially influence later relapse behavior, and that dorsal raphe serotonin (DR 5-HT) input to CA1 may be involved. We inhibited 5-HT1A/1B receptors (WAY100,635 plus GR127935), or DR input (chemogenetics), in CA1 on ED1 to test the role of this pathway on cocaine-seeking persistence 2wk later. We also inhibited 5-HT1A or 5-HT1B receptors in CA1 during conditioned place preference (CPP) for cocaine, to examine mechanisms involved in persistent effects of ED1 manipulations. Inhibition of DR inputs, or 5-HT1A/1B signaling, in CA1 decreased drug-seeking on ED1 and decreased cocaine-seeking 2wk later revealing that 5-HT signaling in CA1 during ED1 contributes to persistent drug-seeking during abstinence. In addition, 5-HT1B antagonism alone transiently decreased drug-associated memory performance when given prior to a conditioned place preference (CPP) test, whereas similar antagonism of 5-HT1A alone had no such effect but blocked CPP retrieval on a test 24h later. These CPP findings are consistent with prior work showing that DR inputs to CA1 augments recall of the drug-associated context and drug-seeking via 5-HT1B receptors and prevents consolidation of the updated non-drug context via 5-HT1A receptors. Thus, treatments that modulate 5-HT dependent memory mechanisms in CA1 during initial abstinence may facilitate later maintenance of abstinence.Significance StatementOne of the most complex issues associated with substance use disorder (SUD) treatment is the development of strategies that assist in the initiation and maintenance of abstinence from drug taking. Herein, we show that the persistent propensity for cocaine-seeking during abstinence can be attenuated by 5-HT1A/5-HT1B receptor antagonists, or by inhibition of dorsal raphe signaling to dorsal hippocampus. Our results provide insight towards potential clinical applications for treatment of addiction in human populations.

Pre-Service Teachers’ Conceptual Understanding and Retention When Taught Osmosis Using Group Discussions
Authors: Kibirige Israel 
Published: March 2024

The effect of Group Discussions (GD) on pre-service teachers taught Osmosis was investigated using a quasi-experimental design with pre-and post-tests. Ninety-four pre-service teachers (N=47) for the Experimental Group (EG) taught using GD, and (N=47) for the Control Group (CG) were taught using the Traditional Approach (TA). Results from post-tests show EG performed better than CG, as indicated by Analysis of Covariance (ANCOVA), p < .05, suggesting that GD improved conceptual understanding. A Mann-Whitney U-test shows no significant differences in performance between males and females in EG, implying GD favoured both genders. In addition, EG retention was higher than CG when tested after an extended period. Thus, the results show that GD improves pre-service teachers’ conceptual understanding and retention. The implication for educators is that the use of GD in teaching biology improves pre-service teachers’ conceptual understanding of Osmosis, and these results have far-reaching implications in teacher education.

Армяне юга России – современная геодемографическая динамика региональных общин (2010-е – начало 2020-х гг.)
Authors: Сущий Сергей Яковлевич 
Published: March 2024

В статье анализируются особенности естественной, миграционной, ассимиляционной динамики армян Юга России в 2010-е – начале 2020-х годов. На основе сравнительного анализа параметров естественного воспроизводства населения Армении, южнороссийских регионов и региональных армянских общин делается вывод, что для большинства последних результирующей их естественной динамики в 2010-е годы являлся минимальный прирост или демографическое равновесие. В межрегиональном взаимообмене с другими территориями России часть южнороссийских армянских общин в 2010-е годы преимущественно теряла население (Астраханская, Волгоградская, Ростовская области, Калмыкия), другая часть увеличивала его (Краснодарский край, Адыгея, Крым, Севастополь). Но в международной компоненте миграционной динамики все региональные группы имели положительное сальдо, которое по размеру значительно превышало межрегиональную составляющую, обеспечивая общий приток армянского населения (наиболее значительным он был в Краснодарском крае, Ростовской и Волгоградской областях). Анализ динамики ассимиляционного процесса позволяет сделать вывод о примерном равновесии в 2010-е годы во всех армянских общинах Юга России демографической убыли и пополнения, связанных с распространением межнациональной брачности и количественным ростом смешанного потомства, обладающего сложной самоидентичностью. Таким образом, зафиксированное Всероссийской переписью 2020 (2021) г. сокращение численности этнических армян на Юге России в 2010-е годы на 24,6% не могло быть следствием ни одного из факторов демографической динамики региональных общин. Согласно выполненному расчету, численность южнороссийских армян в 2010–2021 гг. должна была вырасти на 11,1-11,2% (сокращение могла продемонстрировать только община Калмыкии). Основной причиной данного количественного расхождения представляется существенный недоучет армянского населения во время переписи. Этот недоучет имел серьезную расселенческую специфику: прежде всего были недоучтены горожане (их численность по официальной статистике сократилась за 2010-2021 гг. на 32,3%; сельских армян – на 14,4%). Согласно проведенному исследованию, использование в исследовательской и административной деятельности этнодемографических результатов переписи 2021 г. предполагает проведение предварительного анализа, позволяющего оценить уровень их достоверности (как для России в целом, так и каждой из ее территорий).

The Hidden Indonesian Language Literacy Curriculum In Arabic Language Textbooks For Islamic Junior High School
Authors: Sodiq Syamsul , Alindah Lutfiyah 
Published: March 2024

Many religious-based schools and universities in Indonesia have widely implemented Arabic language textbooks as a learning material. However, Arabic is often considered challenging to learn due to its distinct linguistic origin from the Indonesian language. Therefore, there is a need for effective methods to facilitate students in learning Arabic just as they learn Indonesian. Surprisingly, a covert approach to learning Indonesian is also applied to studying Arabic. There are influential Arabic language textbooks that teach Indonesian grammar implicitly. This research aims to analyze the presence of curriculum of Indonesian language literacy in Arabic language textbooks, mainly for grades VII, VIII, and IX in Indonesian Islamic Junior High Schools (Madrasah Tsanawiyah or MTs). These textbooks were published by the Ministry of Religious Affairs of the Republic of Indonesia in 2020. The research method used is a qualitative descriptive approach, which involves content analysis of each chapter in these three books. The research findings reveal a significant amount of Indonesian language literacy content in Arabic textbooks. This content appears as explanations that serve as material clarification for students. Notably, the Indonesian language explanations account for 10% of the grade VII textbooks and 2% of the grade VIII and IX textbooks. Three forms of Indonesian language literacy content were successfully identified: language for comprehension introduction, comparison, and grammar contextualization.

Published: March 2024

Highlights:

Most homicide victims were predominantly in the productive age range of 21-40 years old.
Males were more likely to be homicide victims than females.

Abstract
Introduction: The injuries of homicide victims are clues in forensic medicine to uncover a possible crime. In Indonesia, there are not many studies on trauma profiles, specifically in homicide cases. This study aimed to provide an overview of the trauma profile of homicide victims at Dr. Soetomo General Academic Hospital, Surabaya.
Methods: This was a descriptive study. Secondary data was collected from 34 forensic examination reports at Dr. Soetomo General Academic Hospital, Surabaya. Data such as age, sex, type of injury, sites of injury, number of injuries, cause of death, and mechanism of death were analyzed statistically.
Results: Most victims were between 21 and 30 years old and 31 and 40 years old (26.47%). Sex was dominated by men (76.47%). The most common type of injury was abrasion (25.71%). The most common injury sites were head-neck (34.34%) and chest-upper back (34.34%). The most common number of injuries was ≥10 (44.12%). The most common cause of death was sharp-force trauma (54.54%), and the most common mechanism of death was exsanguination (54.54%).
Conclusion: Males predominated in the age ranges of 21 to 30 years old and 31 to 40 years old. The most common type of injury was abrasion. The most common sites of injury were the head, neck, and chest upper back. The most common number of injuries was ≥10. Most victims died of sharp-force trauma. Exsanguination was the most common mechanism of death.

Highlights:

ABI was not influenced by diabetic status.
A more severe form of diabetic ulcer was associated with a lower ABI value.

Abstract
Introduction: Diabetic foot ulcer (DFU) is one of the most significant complications of uncontrolled type 2 diabetes mellitus (T2DM) that may affect a patient’s prognosis and quality of life. This study aimed to identify the association between diabetic status, DFU severity, and other clinical factors with ankle-brachial index (ABI) score and category.
Methods: This was a cross-sectional study under a consecutive sampling frame conducted for three months at Universitas Airlangga Hospital, Surabaya. Primary data for ABl were measured from T2DM patients with DFU in the Thoracic and Cardiovascular Polyclinic, while secondary clinical data were collected from the Department of Internal Medicine based on the inclusion and exclusion criteria specified in the patient's medical records.
Results: Out of 30 included patients, 63.33% had uncontrolled diabetic status, and the average ABI score was 0.999 ± 0.19. DFU severity was significantly associated with the ABI score and ABI category. Patients indicated with angioplasty exhibited a markedly lower ABI score than those without (mean 0.32 vs 1.01; p < 0.001). Indication of angioplasty was the only clinical factor significantly associated with a lower ABI score (p < 0.001).
Conclusion: Although the status of T2DM was unrelated to ABI, future research is recommended to advance the understanding of peripheral artery disease in diabetic foot ulcer patients.
