Authors: Selvia Selvi - 
Published: April 2024

Infertility is a condition in married couples who have regular and adequate sexual intercourse for more than one year without using contraception, but have not had a pregnancy or offspring. Factors that cause infertility can be caused by men, women, or even both. Approximately 10% - 15% of couples of reproductive age experience infertility, with the contribution of the male factor, which is equal to 40% -50%. The analysis of embryo development and spermatozoa DNA fragmentation aims to analyze the function of spermatozoa in infertile men and to determine the relationship between sperm DNA fragmentation and embryo development in IVF patients. This study was an experimental study with a total of 30 samples of husband's patients who carried out the IVF program who met the researcher's inclusion criteria. The statistical test results obtained showed that there was a significant relationship between the DNA fragmentation index (DFI) (P<0.05), therefore it can be concluded that further research is needed so that many more things can be explored. of other causes of infertility.

Evaluating the phylogenetic relationship of a dwarf honey bee through cytochrome oxidase subunit 1 (COX1) gene sequence databases
Authors: Shullia Nurul Insani 
Published: April 2024

Dwarf honey bees, Apis florea, and Apis andreniformis are known as the potential wild pollinator in Asia. Apis florea was introduced to Indonesia, West Asia, and Africa. Based on the cytochrome oxidase subunit 1 (COX1) gene, introduced A. florea in Iran is suggested to come from India. Although the databases of the dwarf honey bee COX1 gene are available in GenBank, however, the phylogeny analysis was focused on the restricted area. Thus, this study aims to evaluate the phylogenetic relationship and genetic diversity of dwarf honey bees based on the COX1 gene sequence from GenBank databases. The COX1 gene sequence databases are collected from NCBI. The genetic diversity and phylogenetic relationship are analyzed using MEGAX. Alignment of 530 bp COX1 gene of dwarf honey bee showed that there are 60 nucleotide variations between A. florea and A. andreniformis. Our analysis indicated that the genetic diversity between A. andreniformis is low (0-0.19%). On the other hand, there are 28 nucleotide variations between A. florea and eight nucleotide sites that are suggested as a marker to differentiate A. florea1 India+Egypt+Iran and A. florea2 Thailand+China with 1.7-3.4% genetic distance. The high genetic distance of A. florea is supported by the separation sub-clade of A. florea1 and A. florea2 in the phylogenetic tree.
Public Diplomacy and Democratic Backsliding in Turkey: A Retrospective Look at Government Investment in Soft Power
Authors: Demir Vedat 
Published: April 2024

This paper discusses the development of public diplomacy policies and their implementation by the Turkish government through aggregate investment data and within the broader regional and global context in which the country’s policies evolved. Its main aim is to show how regime type is interrelated with foreign policy in general and public diplomacy as a branch of it. Turkey is a fruitful case because the country has experienced significant democratic backsliding since 2011, unlike the first period when the Justice and Development Party (henceforth AKP) came to power in 2002. The discussion over the data on budgets of various institutions responsible for adopting public diplomacy policies shows that cultural and educational public diplomacy received a major increase in investment, especially within the last six years, whereas the budgets for other institutions have fluctuated over the last ten years. Although the paper’s purpose was to provide a comprehensive picture of Turkey’s public diplomacy throughout the AKP rule since 2002, its main data source remains limited to the last decade. Thus, the availability and transparency of the data and its indication of the relationship between regime qualities and public diplomacy policies are also noted.

Authors: Kurniasih  , Suhartoyo Eko , Fransiskus Ferdinan 
Published: April 2024

At higher education, students at the end of the study are required to write a final project. Writing English papers is challenging and might create writing anxiety. Therefore, it is necessary to look at what strategies are used by the teachers and their effect on anxiety levels and performance. Furthermore, it is also crucial to accommodate students’ perceptions of the strategies so that students’ voices provide valid information on how the classroom should be. This research uses a mixed-method methodology to analyze lecturers' anxiety-reduction strategies and students' perceptions of them. Three instruments were used to collect data, namely a Second Language Writing Anxiety Inventory (SLWAI), open-ended questions about the perception, and students’ writing scores. A paired sample t-test was used to compare students' writing anxiety and performance before and after treatment. Content analysis was used to assess student opinions of the strategies. The statistics showed that students' writing anxiety fell from high (71.35) to moderate (66.47). Meanwhile, students' writing grade rises from 72.00 to 79.03. SPSS analysis showed that anxiety-reducing strategies significantly affect writing anxiety and student performance (p = 0.000). Consequently, this study's findings should be beneficial in writing classes.

Authors: Afidawati Hilda , Arrasyid Farouk Imam , Ikawati Listiana 
Published: April 2024

The COVID-19 pandemic, which lasted for more than 2 years, had a tremendous impact in Indonesia. One of its impacts on the education sector that is still affecting the post-pandemic period is learning loss. Learning loss is a phenomenon where students lose their knowledge and skills due to certain conditions. Learning loss also affects students’ psychology. In speaking learning, anxiety is one of the students' obstacles to speaking fluently. This study aimed to investigate the strategies employed by students to mitigate speaking anxiety in the post-pandemic era. The case study design was used to do an in-depth investigation of complex problems regarding students' speaking anxiety in a school. The study involved six students in grade seven at a junior high school in West Java, Indonesia, as participants. The participants selected were those representing different speaking abilities based on their speaking test results. The data was collected through semi-structured interviews. The findings show that students employ several strategies to mitigate their speaking anxiety, including preparation, relaxation, positive thinking, and peer-seeking. In other words, those strategies reflect students’ resilience to deal with learning loss in the post-pandemic era. This study is intended to serve as a valuable resource for educators and EFL learners by providing strategies to alleviate speaking anxiety effectively.
Moral Values Representation through Speech Acts in Indonesian EFL Textbooks: A Critical Discourse Analysis
Authors: Arwanto Harun , Djatmika Djatmika , Drajati Nur Arifah , Putra Kristian Adi 
Published: April 2024

Abstract: In the last ten years, studies of the representation of moral values in English textbooks have been growing. However, little empirical evidence reveals the use of speech acts to represent moral values through utterances. This study aims to investigate the representation of moral values depicted through utterances in English textbooks for elementary school grades 2 and 5 in Indonesia. By adopting a socio-cognitive critical discourse analysis (Van Dijk, 2015) framework integrated with Searle’s (1969) speech acts, this qualitative study elucidates the representation of moral values only in the verbal text. The data were analyzed by applying several steps, including unitizing, sampling, recording/coding, reducing, inferring, and narrating. The findings of this study showed that curiosity, honesty, and friendliness are the most dominant moral values depicted in two English textbooks for elementary schools in Indonesia. Dialogue/conversation, chapter cover, and instruction for students’ activity are the strategies to promote moral values in the textbooks. This study implies that teachers and textbook writers should provide students with more examples of moral values, particularly those related to daily life communication.
Esoteric Dance Practices of the Early Twentieth Century: Case Study of George Gurdjieff’s Movements
Authors: Maltabarova Makhabbad 
Published: April 2024

Abstract
The beginning of the twentieth century was marked by colossal changes in various spheres of life, including art, where appeared numerous choreographies produced by both professional dancers and esoteric teachers. This article analyzes the choreography of George Gurdjieff, a dance practice simply called “Movements.” This practice was often considered as closely related to and being a product of the artistic environment of the time. The article argues that even though being the product of the time, Gurdjieff’s dance requires a close attention. It will show that his approach to dance downplays aesthetic and emotional aspects. Applying the hybrid methodology, this article will first identify the place of the Movements in Gurdjieff’s teaching. It will then illustrate how the Movements differ from modern German dance. Finally, it will analyze and describe the author’s ethnographic experiences in the study and practice of the Movements.

Authors: Tharinda D. De Silva  , Subhani A. Sarada  , Mailvaganam Pagthinathan  , Wimal A. Perera  
Published: April 2024

Heat stress in livestock animals is one of the promising topics discussed especially with climate change. Even though it is complicated to accurately measure at which point the cattle may suffer from heat stress due to different external and internal factors, mitigation of heat stress is quite important because a cow can lead to hyperthermia if it couldn’t maintain the thermoneutrality of its body. A great number of researches were conducted to find out the factors that lead to heat stress and the effects of heat stress on the production, reproduction, respiratory rates, heart rate, and feeding behaviors of cattle. Mitigation strategies for heat stress were also revealed under different means by mitigating heat exchange pathways which lead to accumulate the heat within the body, and management strategies including nutritional management. The present review was to elaborate on those findings to critically evaluate how dairy cattle are affected by heat stress in the livestock industry and the investigated mitigation strategies of heat stress to regulate the body heat of cattle.

Authors: Oishi Tatsuya , Van Gompel Jamie J. , Link Michael J. , Peris Celda Maria , Daniels David J. , Morris Jonathan M. , Hoffman Ernest M. 
Published: April 2024

OBJECTIVE
The objective of this study was to describe the quantitative features of intraoperative electromyographic recordings obtained from cranial nerve III, IV, and VI neuromonitoring using 25-mm intraorbital electrodes, in the larger context of demonstrating the practicality of this technique during neurosurgical cases.

METHODS
A 25-mm-long shaft-insulated intraorbital needle electrode is routinely used at the authors’ institution for extraocular muscle (EOM) electromyographic monitoring of the inferior rectus, superior oblique, and/or lateral rectus muscles when their function is at risk. Cases monitored between January 1, 2021, and December 31, 2022, were reviewed for patient demographics, tumor location and pathology, EOMs monitored, pre- and postoperative examination, and complications from electrode placement. Compound muscle action potentials on triggered electromyography, as well as neurotonic discharges on free-run electromyography, were described quantitatively.

RESULTS
There were 141 cases in 139 patients reviewed during the 24-month time span, with 278 EOMs monitored (inferior rectus/superior oblique/lateral rectus muscles 68/68/142). Triggered electromyography yielded biphasic or triphasic compound muscle action potentials from EOMs with a mean onset latency of 1.51 msec (range 0.94–3.22 msec), mean maximal peak-to-trough amplitude of 1073.93 μV (range 76.75–7796.29 μV), and high specificity for the channel in nearly all cases. Neurotonic discharges were recorded in 30 of the 278 EOMs (with all 3 muscles represented) and associated with a greater incidence of new or worsened ophthalmoparesis (OR 4.62, 95% CI 1.3–16.4). There were 2 cases of small periorbital ecchymosis attributed to needle placement; additionally, 1 case of needle-related intraorbital hematoma occurred after the review period.

CONCLUSIONS
The 25-mm shaft-insulated intraorbital electrode facilitates robust and consistent electromyographic recordings of EOMs that are advantageous over existing techniques. Combined with the relative ease of needle placement and low rate of complications, the technique is practical for neuromonitoring during craniotomies.

Published: April 2024

OBJECTIVE
This study aimed to investigate whether high homocysteine (Hcy) levels associated with the MTHFR gene influence the formation of the collateral vascular network in patients with moyamoya disease (MMD) after encephaloduroarteriosynangiosis (EDAS) by influencing the number of endothelial progenitor cells (EPCs) in peripheral blood.

METHODS
A total of 118 Chinese patients with bilateral primary MMD were prospectively included. Blood samples were collected from the anterior cubital vein before surgery, and MTHFR rs9651118 was genotyped using high-throughput mass spectrometry to determine the genotype of the test specimen. Serum Hcy and EPC levels were measured, the latter with flow cytometry. Digital subtraction angiography was performed 6 months after EDAS, and the formation of collateral circulation was evaluated using the Matsushima grade system. The correlations between MTHFR rs9651118 genotype, Hcy and EPC levels, and Matsushima grade were compared.

RESULTS
Among the 118 patients, 53 had the TT genotype (wild type) of MTHFR rs9651118, 33 TC genotype (heterozygous mutation), and 32 CC genotype (homozygous mutation). The mean ± SD Hcy level was 13.4 ± 9.5 μmol/L in TT patients, 9.8 ± 3.2 μmol/L in TC patients, and 8.9 ± 2.9 μmol/L in CC patients (p < 0.001). The level of EPCs in the venous blood of TT patients was 0.039% ± 0.016%, that of TC patients 0.088% ± 0.061%, and that of CC patients 0.103% ± 0.062% (p < 0.001). When the rs9651118 gene locus was mutated, Matsushima grade was better (p < 0.001) but there was no difference between heterozygous and homozygous mutations.

CONCLUSIONS
The results suggest that the MTHFR rs9651118 polymorphism is a good biomarker for collateral vascular network formation after EDAS in MMD patients.

Published: April 2024

OBJECTIVE
The aim of this study was to delineate the clinical and socioeconomic variables associated with shunt revision in pediatric patients presenting to the emergency department (ED) with concerns of ventricular shunt malfunction.

METHODS
A retrospective analysis of pediatric ED consultations for shunt malfunction over a 1-year period was conducted, examining clinical symptoms, radiographic findings, and socioeconomic variables. Sensitivities, specificities, and positive and negative predictive values were calculated for each presenting symptom collected. Logistic regression models were used to estimate the odds ratios for shunt revision based on these variables, and multivariate analyses were used to adjust for potential confounders.

RESULTS
Of the 271 ED visits from 137 patients, 19.2% resulted in shunt revision. Increased ventricle size on imaging (OR 11.38, p < 0.001), shunt site swelling (OR 9.04, p = 0.01), bradycardia (OR 7.08, p < 0.001), and lethargy (OR 5.77, p < 0.001) were significantly associated with shunt revision. Seizure-like activity was inversely related to revision needs (OR 0.24, p < 0.001). Patients with private or self-pay insurance were more likely to undergo revision compared with those with public insurance (p = 0.028). Multivariate analysis further confirmed the significant associations of increased ventricle size, lethargy, and bradycardia with shunt revision, while also revealing that seizure-like activity inversely affected the likelihood of revision. Patients with severe cognitive and language disabilities were more likely to be admitted to the hospital from the ED but were not more likely to undergo revision.

CONCLUSIONS
Clinical signs such as increased ventricle size, shunt site swelling, bradycardia, and lethargy may be strong predictors of the need for shunt revision in pediatric patients presenting to the ED with concerns of shunt malfunction. Socioeconomic factors play a less clear role in predicting shunt revision and admission from the ED; however, the nature of their influence is unclear. These findings can help inform clinical decision-making and optimize resource utilization in the ED.
Silence, Well-being and Learning
Authors: Maley Alan 
Published: April 2024

I am approaching this article from the viewpoint of an ordinary human being, condemned to live in the 21st century – and of a language teaching practitioner. I have no pretensions to academic scholarship, nor to research into silence, so this will be a purely personal view.I will first examine the negative effects that loss of silence has had on us as individuals and society. I will then suggest some ways in which we can palliate these effects in our individual lives. Finally, I will discuss the value of silence in learning (with a focus on language learning) and suggest some ways we might incorporate positive aspects of silence in our teaching.
