Professional English language teachers are expected to master subject knowledge that includes not only their knowledge of English language but also their proficiency in using the language. They can self-assess their proficiency and use their assessment result as the basis for their professional growth since it can inform which areas that still need improvement. Despite the importance of teachers’ self-assessment, there has not been much research on this, especially one that investigates the teachers’ perceived receptive skills. This study, therefore, aims to explore the in-service teachers’ perception of their proficiency level, particularly of their receptive skills. This research uses a descriptive quantitative approach utilizing a survey containing 48 questions of self-perceived reading and listening skills which was distributed to in-service teachers in lower and higher secondary schools in Indonesia. This snowball survey received responses from 449 in-service teachers from various islands in Indonesia such as Java, Bali, Sumatera, Sulawesi, Kalimantan, and Papua. The results show that, in general, the participants considered themselves to be able to comprehend various text types concerning personal and daily issues in both written and spoken modes. However, when it came to comprehending longer texts with more complex linguistic choices and structures in both modes, an increase in the number of participants who struggled was evident. These findings indicate that while most of the in-service teachers were confident in their receptive skills. However, while only limited numbers of in-service teachers’ facing difficulties in comprehend longer and more specialized texts containing complex linguistic resources, support is still needed. Based on these findings, this study discusses several important implications for teacher educators and English teachers in Indonesia and offers recommendations for future research in EFL contexts.

Oral diseases, such as dental caries and periodontal diseases are major worldwide oral health problems. Poor oral health has a profound effect on general health and quality of life. Dental caries is still a major health problem in most industrialized countries, school-aged children and the vast majority of adults. Streptococcus mutans is considered as one of the most important cariogenic species of the human oral microbial flora. Studies have proved the association between S. mutans and dental caries. Traditional Indian system of medicine “Ayurveda” includes several important medicinal herbs, which are used since ancient days. Triphala, which has a wide range of systemic benefits, is one among them. Studies have shown that Triphala has good antimicrobial effects against S. mutans. Ferula assa-foetida (F.assa-foetida), is a large herbaceous perennial plant from the Apiaceae family. The properties of Assa-foetida according to Traditional Persian Medicine resources suggest it is very effective for relieving toothache. Different parts of F. assa-foetida have a wide variety of medicinal applications including antifungal, anti-diabetic, anti-inflammatory, anti-mutagenic and anti-microbial effects. To compare and evaluate the antimicrobial efficacy of Triphala, Assa-foetida and 0.2% Chlorhexidine mouth rinses on the salivary Streptococcus mutans level. Saliva samples were collected from children of age group of 5-11 years with a DMFT/def score ≥4 and with minimum of four active caries. Triphala and Asafoetida mouth rinses were prepared indigenously. Samples were plated on the culture media and then smeared on MHA media for assessing the antimicrobial efficacy against Chlorhexidine. The zone of inhibition was measured which showed the resistance against S.mutans. Results were statistically analyzed using one way ANOVA. Significant resistance was noted with asafoetida mouth rinse by measuring the zone of inhibition. Considering the results, Triphala and asafoetida mouth rinses serve as effective herbal mouth rinses for reducing the salivary Streptococcus mutans load and can be considered as an alternative to chemical mouthwash, like Chlorhexidine.

Background: Current medications especially the pentavalent antimonial compounds have been used as the first line treatment of cutaneous leishmaniasis (CL), but they have limitations due to serious side effects such as drug resistance, cardio and nephrotoxicity, and high costs. Hence, the demand to find more usable drugs is evident. Synthesis and devel­opment of natural, effective, biocompatible, and harmless compounds against Leishmania major is the principal priority of this study.
Methods: By electrospinning method, a new type of nanofiber were synthesized from royal jelly and propolis with dif­ferent ratios. Nanofibers were characterized by Scanning Electron Microscope (SEM), Transmission Electron Micros­copy (TEM), Thermogravimetric Analysis (TGA), Contact angle, and Fourier-transform infrared spectroscopy (FTIR). The Half-maximal inhibitory concentration (IC50), Half-maximal effective concentration (EC50) and the 50% cytotoxic concentration (CC50) for different concentrations of nanofibers were determined using quantitative calorimetric meth­ods. Inductively coupled plasma-optical emission spectrometry (ICP-OES) and flow cytometry were performed as com­plementary tests.
Results: The results showed that the proposed formulas provide a new achievement that, despite the significant killing activity on L. major, has negligible cytotoxicity on the host cells. Royal jelly nanofibers have significantly shown the best 72 hours results (IC50= 35 μg/ml and EC50=16.4 μg/ml) and the least cytotoxicity.
Conclusion: This study presents a great challenge to introduce a new low-cost treatment method for CL, accelerate wound healing, and reduce scarring with minimal side effects and biocompatible materials. Royal jelly and propolis nanofibers significantly inhibit the growth of L. major in-vitro.

Background: Malaria has remained the most dreadful vector-borne disease; hence, vector control is the most affordable and achievable approach to mitigate the disease burden. Due to the emergence of resistance and environmental pollu­tion, herbal larvicides are considered an alternative to chemical types. Also, nanotechnology has been proposed as a prom­ising solution to improve the efficiency of plant larvicides. This study aimed to develop an effective herbal larvi­cide.
Methods: The chemical composition of Elettaria cardamomum essential oil (EO) was first investigated. Nanolipo­somes containing the EO were then prepared using the ethanol injection method. After that, the larvicidal efficacy of the EO and its liposomal state were compared against Anopheles stephensi in laboratory conditions.
Results: Alpha-terpinyl acetate (77.59%), eucalyptol (4.38%), nerolidol (2.96%), linalool (1.77%), and limonene (1.69%) were the five major compounds of the EO. Nanoliposomes containing the EO with a particle size of 73±5 nm and a zeta potential of -16.3±0.8 mV were prepared. Additionally, the ATR-FTIR analysis verified the successful load­ing of the EO into nanoliposomes. The larvicidal activity of nanoliposomes exhibited remarkable potency, with an LC50 value of 14.35 (10–18) µg/mL, significantly more potent than the non-formulated EO, which had an LC50 value of 33.47 (28–39) µg/mL against Anopheles stephensi larvae.
Conclusion: The nanoliposomes containing E. cardamomum EO showed promising efficacy against An. stephensi lar­vae. It could thus be considered for further application against other species of mosquitoes.

Background: Indoor residual spraying (IRS) and long-lasting insecticidal nets (LLINs) are two core interventions for control and prevention of malaria infection. This descriptive cross-sectional study aimed to determine the knowledge and practices of women regarding malaria and its preventive measures in a malarious area in the Jask County, southeast of Iran.
Methods: Data was collected from 400 households through a two-stage random cluster sampling method in six villages. Pre-tested structured questionnaire was used to collect data. During the survey, visual observations were also made by the interviewers to check use of LLINs and IRS. The data were analyzed by SPSS software version 21.
Results: The majority of households had a high level of knowledge about symptoms (98%, n=392) and transmission (74.5%, n=298) of malaria. The main preventive measures against malaria were: LLINS (39.5%, n=158), IRS (32%, n=128), and screens on doors/windows (16.7%, n=67). In addition, participants with primary or higher educational level reported that they practice more malaria preventive measures, compared to those who were illiterate (OR=3.3, 95% CI= 1.6–6.6, p=0.0001, Table 6). In spite of positive perceptions about IRS and LLINs, only 35.5% (n=142) and 17% (n=68) of households used IRS and LLINs, respectively.
Conclusion: According to the results of this study, despite a high level of knowledge about malaria and its preventive measures, a small number of participants use LLINs and IRS for malaria prevention. Therefore, implementation of ef­fective educational interventions is recommended to improve preventive practices against malaria in the study area.

Published: April 2024

In this paper morphological-hydrographic changes in the area of the coal open pit "Turija" in Banovići basin (north-eastern Bosnia and Herzegovina) are researched. The study was based on the field data and comparative analysis of topographic maps, satellite images, Digital Elevation Model and situational plans of the open pit area. With conducted GIS analysis of natural and anthropogenic relief of open pit "Turija" the changes in the structure of hypsometric level, slope and aspect, and the changes in the surface hydrographical network etc. are determined. The general trend of ground levelling, decrease in altitude differences, gradual disappearance of physical micro relief, disappearance of geomorphologic boundaries on the surface, disorganization of hydrographical network, the development of positive and negative forms of relief, and greater presence of physical-anthropogenic processes and forms in relation to physical ones are determined. Reduction of territories with southerly, easterly and westerly aspects, and a significant increase in territories with northerly aspect is also determined. Geospatial data obtained by GIS after their analytical and synthetic processing are geovisualized. Ten thematic maps were made and they provide insight into resulted changes in the researched geographical area. The explored indicators can serve as a significant factor in the future planning and selection of the type of re-cultivation of degraded areas in the area of research.

Published: April 2024

Children frequently suffer from motor impairments which hinder their development. Every movement requires stability therefore; musculoskeletal malfunction leads to poor movement. Task-oriented training is one of many methods and techniques used to promote motor skills and daily physical activities in children. The present study's goal is to investigate how task-oriented training contributes to developing motor skills and daily physical activities in learners with cerebral palsy. The study employed a mixed- data collection strategy. The study included a total of 12 students with cerebral palsy. The promotion of a child's motor abilities and regular physical activity can be accomplished with the help of task-oriented training. The study's findings supported our hypothesis that task-oriented training that has been devised and a series of exercises to increase range of motion (flexibility) led to positive dynamics in all groups of indicators regardless of the severity of the pathology. The proposed program allowed children to increase muscle strength and range of motion in the joints. Thus, after the experimental work, the functional state of the musculoskeletal system improved and qualitative and significant changes occurred in the independence of learners. It is suggested that teachers use task-oriented training when instructing school-age children who have this disorder.
Reducing stereotypical behaviors using augmented reality in children with autism spectrum disorder
Authors: Gaber Sherif Adel 
Published: April 2024

Augmented reality (AR) has been shown to have a positive impact on children with autism spectrum disorder (ASD) because it can effectively simulate the real environment through interactive experiences created by the integration of digital elements with the outside world. This research aimed to verify the effectiveness of a training program based on AR for reducing stereotypical behavior (SB) in a sample of children with ASD. The study sample consisted of 16 male students with ASD who were enrolled in the Autism Institute in Al-Ahsa, Saudi Arabia, ranging from 8 to 13 years of age. The researcher also developed a training program and employed a quasi-experimental method in addition to research instruments including the Stereotypic Behavior Scale (SBS). The results of the analysis show statistically significant differences between the mean ranks of the participants in the three tests (pre-, post- and follow-up) on the SBS (x2 = 30.471, p < 0.001) which indicates the effectiveness of AR in reducing participants’ SB. Additionally, it demonstrates that the training impact lasts for two months after the end of the program. According to the research, AR-based software applications have the potential to improve children with ASD's socialization and interaction abilities. It is recommended to do additional research using larger sample sizes and controlled designs.
