Authors: Álvarez García Horacio Balam , Lugo-González Isaías Vicente , González Betanzos Fabiola
Published: May 2023

Background: Insomnia is the sleep disorder with the highest incidence worldwide. It is estimated that this condition increases the risk of developing psychiatric, neurological, and cardiovascular problems. Due to this, it is important to have brief, reliable and valid psychometric instruments that allow health personnel their timely detection in first level health centers. Objectives: Analyze the psychometric properties of the Insomnia Severity Index (ISI) in its version adapted to Spanish in a sample of Mexican adults. Methods: The sample consisted of 310 adults, 223 (71.9%) women and 87 (28.1%) men. The comparison of four ISI measurement models of one, two and three factors and a bifactor model was carried out, its internal consistency was analyzed, an analysis of invariance by sex and correlation analysis with the Athens and Epworth scales. Results: The ISI bifactor model with a general factor (G) and a specific factor for insomnia impact (I) showed the best fit indices (χ2= 29.48, gl = 11, SRMR= 0.03, CFI= 0.98, TLI= 0.96, RMSEA= 0.07), and demonstrated configural, metric, and scalar invariance by sex. Adequate reliability was demonstrated by Omega coefficients (General: ωG= 0.86, Impact: ωI= 0.86) showed adequate reliability; the scale showed very strong correlations with the Athens scale (rAGoverall= 0.84; rAImpact=0.75) and weak to moderate correlations with the Epworth scale (rEGeneral= 0.39; rEImpact=0.44). Conclusions: The ISI bifactor version in Spanish presents adequate psychometric properties for the measurement of insomnia and, as it is a brief tool, it can be used at different levels of health care.

Published: May 2023

This study compares the result of the PID controller to the LQR controller when used in the on-orbit stabilization of a satellite in the low earth orbit. The results from the PID controller show that the controller is too weak when used alone as the controller could not stabilize the system after 500 s which is not even allowable in practical application. For the LQR controller, a performance metric was set which is: i. the settling time is to be ≤ 10 seconds, ii. Maximum power consumption ≤ 1.5 Watts and iii. Zero (0) steady-state error / final value. The LQR controller meets system performance by achieving a settling time of roll (peak amplitude=0.26 s, settling time=10.0 s), Pitch (peak amplitude=0.395 s, settling time=5.52 s), Yaw (peak amplitude=0.350 s, settling time=5.52 s) and Total power consumption are 1.26 watt with a maximum torque of 3.22 mNm. Because power consumption and precision are critical in satellite applications, particularly military surveillance satellites. As a result, for an aerospace engineer to achieve their space mission, for instance, space mission like low earth orbit surveillance satellites, flexible solar panels, a high accuracy pointing accuracy, it will be impossible to adopt a PID controller except the engineer is ready for the complexity of design filters and compensators. An LQR design in this study can take care of all this complexity with minimum power consumption.

Published: May 2023

Problem-solving Skills and Reading-Writing Literacy are two necessary things students must have to compete in the 21st century. This study aims at determining the effectiveness of Problem-based Learning with Integrated Reading and Writing tasks to improve students' problem-solving and reading-writing literacy skills. A quantitative method using a quasi-experimental design with a non-equivalent control group was employed in this study. The sampling technique used in this study was the purposive sampling technique. The sample used in this study was 36 students divided into two groups: the control group and the experimental group. The instrument used in this study was a physics problem-solving skill test instrument and a reading-writing literacy instrument. The data analysis technique in this study was a quantitative analysis technique. The results showed that the N-gain value of the physics problem-solving skill test for the experimental group was 0.67 in the medium category, and the control group was 0.65 in the medium category. In the reading-writing literacy test, the N-gain value for the experimental group was 0.55 in the medium category and 0.29 in the low category for the control group. The Problem-based Learning model with Integrated Reading and Writing Tasks has little impact on improving students' problem-solving skills. However, it has a significant effect on increasing students' reading-writing literacy.

Prescriptions for the positron emission tomography-computed tomography (PET-CT) in adult cancer patients are based on the results of multicenter studies, systematic reviews, and meta-analyses. Thus, published international guidelines help nuclear medicine specialists, oncologists and radiologists in determining the most appropriate diagnostic algorithms for each patient with the purpose of selecting the most appropriate treatment as well as allowing the introduction of the new prognostic factors. Compared with adult patients, the use of PET-CT in pediatric oncology is somewhat limited due to the lack of systematic, large multicenter studies and, therefore, precise and clear guidelines. The reasons for the lack of the large studies may be the relatively low incidence of malignant neoplasms in pediatric practice and the fear for the delayed effects of exposure of ionizing radiation on the growing child's body. The purpose of this bibliographical review was to provide a summary of the use and the role of PET-CT in children with the most frequent malignancies.

Thromboses in children represent the serious pathology that can lead to disability and even death of a pediatric patient. At certain localizations of thrombosis, the most rapid restoration of vascular patency (reperfusion) becomes prognostically significant. The most accessible method for reperfusion is drug therapy, in which a drug is injected into the patient's blood, which in its turn significantly accelerates the process of fibrinolysis, i.e., thrombolytic therapy (TT). The purpose of this bibliographical review was to familiarize physicians, especially pediatricians with the place of TT in modern clinical practice. The article represents bibliographical review of published works for over 50 years (since 1966). Authors have used both domestic Russian resources and the PUBMED database. Articles were selected based on the relevance. Statistical analysis was not performed. A review and analysis of bibliographical data on the modern use of TT in pediatric practice is presented. Preference was given to the most modern publications containing analytical information with full text available both pro bono and online. Authors emphasize pediatric practitioners’ attention on the fact that TT at the current level of knowledge is a fairly effective and predictable method for rapid reperfusion.

Reactive blood changes are a heterogeneous group of pathological conditions that can occur in response to various conditions: viral, bacterial infections, helminth toxins, allergic agents. These reactions often require differential diagnosis with malignant neoplasms (MN) of the blood and hematopoietic organs (leukemias, lymphomas). It is important to note that only with a comprehensive examination of the patient with the involvement of a pediatric oncologist and hematologist, it is possible to exclude MN and carry out etiotropic treatment that contributes to the normalization of hemogram parameters. Article represents current data on the etiopathogenesis of leukemoid reactions, reactive thrombocytosis, secondary erythrocytosis and a clinical case observation of the development of a pseudoblast leukemoid reaction and reactive thrombocytosis against the background of an infectious process in a patient with Peutz-Jeghers syndrome, which will be of use to a wide range of pediatric practitioners.

The article is about the experience in treating of pediatric patients with tumors of the pancreas who have undergone the gastro-pancreatoduodenal resection (GPDR) and pancreatoduodenal resection (PDR) at the Research Institute of Pediatric Oncology and Hematology named after Academician L.A. Durnov with the N.N. Blokhin Russian Cancer Research Center (Moscow, Russia). These kinds of surgical interventions are performed both with local neoplasms of the pancreatic head and with the spread of the tumor process to the duodenum, distal part of the stomach, and parapancreatic tissue. Materials and methods used: 13 GPDR, PDR surgical interventions were performed in children aged 5 to 16 y/o in 2010-2022. The results of treatment of these patients were assessed as satisfactory despite the complications that arose in some patients in the early and late postoperative periods. All patients are alive. GPDR surgical interventions were performed in 6 patients, and PDR in 7. The most frequently verified were solid pseudopapillary tumor of the pancreatic head (in 10 cases), neuroendocrine tumor (in 2 cases) and paraganglioma in a single case. Discussion and conclusions: bleeding from the pancreatic branch of the splenic artery and acute pancreatitis were noted among the early postoperative complications. Recurrent phenomenon of enzyme evasion and syndrome of excessive bacterial growth were revealed in the late postoperative period. Despite the complications arisen all patients are alive without signs of recurrence of the disease. The prognosis for this category of patients with radically performed surgical intervention is favorable.
Analisis Kontrastif Strategi Penterjemahan Harf al-Jar dalam Kisah Ibnu Yaqzan
Authors:   Universiti Sultan Zainal Abidin, BINTI ZULKIFLI SITI ZUBAIDAH
Published: May 2023

The field of translating Arabic into Malay is gaining ground among translators and students of Arabic. In fact, studies related to the field of Arabic-Malay translation are widely studied in various branches of linguistics, but studies related to contrastive analysis of Arabic-Malay translators are still relatively under-studied, mostly on harf al-jar. The main reason for the translation of the harf al-jar into Malay is the translator's inability to produce an accurate match of the harf al-jar in Malay, which can affect the original meaning of the original source text. Therefore, this paper aims to highlight aspects of the good translation of harf al-jar through the matching of harf al-jar to the Malay language in the Arabic-Malay translation of Ibnu Yaqzan's novel. In addition, this paper also identifies the strategy used by the translator Ibnu Yaqzan in translating harf al-jar into Malay. This study was conducted using a qualitative method through a contrastive and descriptive analysis of the translation of harf al-jar in the story of Ibnu Yaqzan. The research findings suggest that the letters al-jar in Ibnu Yaqzan's story are not translated literally, but instead are translated according to the meaning intended by the author. In addition, the translation of harf al-jar into Malay in this story uses communication strategies, dynamic strategies, and relevant theories. Accordingly, this paper suggests that the contrastive analysis of the translation of harf al-jar should be given attention and highlighted to translators and Arabic language students so that they do not get confused in translating letters. The aspects of the translation of the harf al-jar presented in this study can be used as a guide and reference for students and Arabic-Malay translators in producing an accurate and authentic translation of the harf al-jar into the Malay language.
All Too Well Versus Uptown Funk: An Indirect Theory of Mind Replication Using Writerly and Readerly Song Lyrics in a Plurilingual Setting
Authors:   Universiti Sultan Zainal Abidin, Ashari Siti Auji
Published: May 2023

The theory of mind, at its core, concerns the emotional intelligence, our empathy, and the ability to read and interpret the mental states of others we interact with. In the early 2010s, Kidd and Castano (2013) carried out a seminal research to investigate the theory of mind effects of reading literary fiction versus reading popular genre fiction, nonfiction, and no reading. The researchers found that the former enhanced the performance in the theory of mind test, namely the Reading the Mind in the Eyes Test (RMET), more than the latter three did. Consequently, the original researchers encouraged the replications of their research, either directly or indirectly using other media. The present paper reports on one such replication, using song lyrics as the indirect medium. Conducted with 29 undergraduate medical students at plurilingual UCSI University Terengganu Campus, the results show that the writerly All Too Well group performed the best in the RMET, whereas there was no significant difference in the RMET performance between the readerly Uptown Funk group and the control group. For this study, therefore, the theory of mind effects were positive only for the writerly texts, but not for the readerly. Accordingly, this paper calls for more future replications, especially indirectly using media other than book excerpts, on the theory of mind effects.

Published: May 2023

We have successfully synthesized magnetic chitin (MCH) by incorporating iron oxide nanoparticles into biodegradable and abundantly naturally available chitin by the coprecipitation method. X-ray diffraction (XRD) characterization revealed formation of cubic inverse spinel structure of Fe3O4 nanoparticles. In addition to this, other characterization studies like energy dispersive X-ray analysis (EDX) and vibrating sample magnetometry (VSM) were also performed to have an insight into the compositional and functional nature of the structure. A detailed spectroscopic study of complex impedance and dielectric constant for a wide frequency range of ~1 Hz to 10 MHz at discrete temperatures ~300–400 K has been performed by us for the first time on MCH in order to understand various relaxation processes. From permittivity, we have estimated the height of the potential barrier to be ~95.8 ± 0.3 meV. Impedance measurements yielded an activation energy of ~35.85 meV. Thermogravimetric analysis (TGA) of the sample showed exceptionally high thermal stability of the sample with percentage of residual mass at 800 ℃ being ~73% in MCH, which is quite high in comparison to the pristine chitin. An S shaped curve obtained through VSM measurement confirmed the superparamagnetic nature of the nanocomposite. The study assumes significance in the present scenario of rising awareness about the environment and demand to explore alternative green materials with numerous biomedical/environmental applications ranging from drug delivery vehicles in COVID-19 treatment to food packaging.

Using artificial neural networks to predict the reference evapotranspiration
Authors: El-Magd Amal Abo , Baraka Shaimaa M. , Eid Samir F.M.
Published: May 2023

Artificial neural network models (ANNs) were used in this study to predict reference evapotranspiration ( ETo) using climatic data from the meteorological station at the test station in Kafr El-Sheikh Governorate as inputs and reference evaporation values computed using the Penman–Monteith (PM) equation. These datasets were used to train and test seven different ANN models that included different combinations of the five diurnal meteorological variables used in this study, namely, maximum and minimum air temperature ( Tmax and Tmin), dew point temperature ( Tdw), wind speed ( u), and precipitation (P), how well artificial neural networks could predict ETo values. A feed- forward multi-layer artificial neural network was used as the optimization algorithm. Using the tansig transfer function, the final architected has a 6-5-1 structure with 6 neurons in the input layer, 5 neurons in the hidden layer, and 1 neuron in the output layer that corresponds to the reference evapotranspiration. The root mean square error ( RMSE) of 0.1295 mm∙day –1 and the correlation coefficient ( r) of 0.996 are estimated by artificial neural network ETo models. When fewer inputs are used, ETo values are affected. When three separate variables were employed, the RMSE test values were 0.379 and 0.411 mm∙day –1 and r values of 0.971 and 0.966, respectively, and when two input variables were used, the RMSE test was 0.595 mm∙day –1 and the r of 0.927. The study found that including the time indicator as an input to all groups increases the prediction of ETo values significantly, and that including the rain factor has no effect on network performance. Then, using the Penman–Monteith method to estimate the missing variables by using the ETo calculator the normalised root mean squared error ( NRMSE) reached about 30% to predict ETo if all data except temperature is calculated, while the NRMSE reached about of 13.6% when used ANN to predict ETo using variables of temperature only.

Authors: Chang Nicholas , McKee James , Marmolejo Valerie , Cua Arnold
Published: May 2023

Introduction. Mucormycosis is a rare but serious angioinvasive fungal infection that can affect the cutaneous system. Primary cutaneous mucormycosis is caused by direct inoculation and is most prevalent in immunocompromised hosts, particularly those with diabetes. A high index of suspicion is necessary for this condition in patients with rapid and deep extension of necrosis despite aggressive surgical intervention. Deep tissue specimens should be sent for fungal culture and histologic analysis for confirmation of the diagnosis. Early and aggressive debridement to prevent spread to deeper tissues and organs, concurrent antifungal therapy, and medical management of comorbidities are paramount to the treatment of primary cutaneous mucormycosis. Case Report. This case report highlights the presentation and recommended treatment of primary cutaneous mucormycosis in 1 patient for reduced morbidity and mortality associated with this type of infection.

Published: May 2023

The continuous discharge and the presence of the plastic wastes are global environmental issues requiring immediate mitigation and prevention measures to avoid and safeguard the marine biota and human health. Distribution, fate and effects of microplastics on the environment have gained more attention in recent years. The present study aims to synthesize the available data of microplastics to identify the load and trend of abundance in marine environment of South China Sea and the Gulf of Thailand based on mounting evidences on the microplastics reports. The major input of the microplastics to the South China Sea was contributed by Pearl River and the Mekong Rivers of Vietnam and Cambodia. Among the available literature, the Gulf of Thailand found medium plastic abundance level when compared to the other surrounding areas. The outcome of these findings will be an aid in providing the management strategies and decision making in decreasing the entry of microplastics into the South China Sea and Gulf of Thailand which are considered as the most sensitive hotspots in contributing the discharge of plastics into the marine environment.

A radical-polar crossover approach to complex nitrogen heterocycles via the triplet state
Authors: Lockhart Zachariah , Popescu Mihai , Alegre-Requena Juan , Ahuja Jay , Paton Robert , Smith Martin
Published: May 2023

The transition from radical to ionic reactivity is a key design feature of many photochemical reactions, enabling complex transformations not possible under either mechanistic regime alone. Ground state alkenes are common substrates in existing methods of this type, serving as radical acceptors to generate open-shell intermediates from which the radical–polar crossover (RPC) event is oxidatively or reductively triggered by a photocatalyst. Here, we describe an alternative RPC mechanism proceeding via an alkene triplet diradical. In this transformation, an iodine radical liberated during a homolytic aromatic substitution step functions as a single electron oxidant to generate an iminium electrophile that can be intercepted en route to complex natural product-like amines. An enantioselective variant of the reaction, enabled by an oxidatively installed sulfinyl leaving group, points to the generality of this underdeveloped pattern of diradical reactivity, paving the way to other triplet-state reactions that incorporate both one and two electron bond-forming processes.

Linker structures were systematically investigated for use in designing halogen-bond donor catalysts with two-point activation modes based on perfluoroiodobenzenes. Tetrafluorophenylene, phenylene, and acetylene were examined as potential linkers, and perfluoroiodobenzenes containing these linkers were successfully synthesized. Their activities were evaluated in terms of binding constant K (M–1) for Cl– and reaction yield (%) in the Mukaiyama- Mannich-type reaction of isoquinoline, and the catalyst with the acetylene linker exhibited the highest activity. The significance of the two-point mode was postulated based on the X-ray diffraction analysis of the acetylene-linked halogen-bond donor with two halogen-bond donor sites. Computational studies revealed the effect of the linker on Cl– binding via halogen bonding. Finally, the utility of the acetylene- linked two-point halogen-bond donor catalyst in the Mukaiyama- Mannich-type reaction was established using various substituted isoquinolines, chloroformates, and ketene silyl acetals.

Aim. To evaluate the age dependence of efficacy and safety in high-pressure balloon dilatation (HPBD) for primary obstructive megaureter (POM) in children under 2 years.
Materials and methods. From 2020 to 2022, we performed a single-center, unblinded study, with a total of 200 children, treated with HPBD for POM: 117 boys and 83 girls. Study included patients from 1 month to 2 years. The follow-up period was 1 year.
Results. In this series the overall treatment effectiveness was 92.5%. In 15 cases treatment was not effective and these children proceeded with ureteral reimplantation. We didn’t achieve positive treatment results in children older than 15 months and our statistical model was not significant for failed cases. Treatment failure we presumed to be due to hard to dilate severe stenosis and extreme length of the stenotic area.
Conclusion. In our study we found HPBD of uretero-vesical junction to be safe and effective method for treatment of primary obstructive megaureter in young children. The overall success rate was 92.5%. We recommend considering HPBD as the first line treatment for POM in young children. In failure cases we suggest to perform ureteral reimplantation.

The lack of security in Internet of Things (IoT) infrastructure across different applications has attracted the attention of researchers to work on IoT security issues. The paper presents a scenario where blockchain technology is combined with IoT to provide a decentralized security mechanism. Secure authentication and Key-Agreement technique are proposed for IoT nodes and peers to ensure proper authorization before communication can take place. The proposed protocol uses public key cryptography to generate a shared symmetric key for mutual authentication and two-party conversation. The protocol was tested using Scyther and was found to be robust enough to withstand all known authentication-related attacks, including replay, and typing attacks. Hyperledger, a blockchain technology, was employed to provide a more efficient IoT-enabled infrastructure for the scalability of IoT devices on the network. The proposed technique provides a secure and scalable system for device authentication in a blockchain-enabled IoT environment.

Background: Considering the development model adopted in Brazilian agriculture, which is based on the increasing demand for chemicals, studies that analyze the impact of pesticide use are relevant to measure the developments in affected populations. Objective: The aim of this study was to conduct a literature review using the digital platform, searching for scientific publications from 2009–2019 on exposure of pregnant women to pesticides. Methods: We used PubMed to search for scientific articles published between January 1, 2009, and December 31, 2019, and related to exposure of pregnant women to pesticides in rural areas. Results: Initially, 207 publications were selected considering the titles and abstracts. Literature works that did not meet the inclusion criteria were excluded. After selection, 15 studies remained. According to the publications on the exposure of pregnant women to pesticides in rural areas from 2009 to 2019, it was found that the damage caused by pesticide exposure to the health of pregnant women and their babies includes problems in gestational weight gain, premature birth, low birth weight, presence of pesticides in blood of both mother and newborn, presence of agricultural pesticides in the cerebral cortex of fetus, and miscarriages. Conclusion: Future prospective studies at individual level are needed to better assess the potential impact of pesticide exposure on the health of pregnant women and newborns.

Studying innovative work behaviour in the Industrial Age 4.0 is an interesting research issue. Using an internal locus of control as a moderator, this study seeks to understand how transformational leadership and organisational climate might promote innovative work behaviour. One hundred and twenty-five respondents participated in this quantitative research, where they were selected based on a purposive sampling method. A cross-sectional survey was conducted to collect the data utilising established instruments looking into the perspectives of the respondents about transformational leadership, organisational climate, innovative work behaviour, and internal locus of control. Data analyses were conducted using SPSS 24 version, where descriptive and inferential analyses, multiple linear analysis and moderated regression analysis (MRA) were undertaken. Based on the analysis, the study's results showed that transformational leadership has a negative and small impact on innovative work behaviour. Organisational climate and internal locus of control were found to positively and moderately impact innovative work behaviour. However, the internal locus of control is needed to moderate the impact of transformational leadership on innovative work behaviour. Based on these results, the hotel industry needs to consider transformational leadership attitudes to create innovative behaviour in human resources, especially in this industry. In addition, it is hoped that future research in this area can be focused on different types of job and gender to produce even better results.

This study responds to the Technological Acceptance Model (TAM) critics regarding the model's missing self-regulatory and motivational variables. The research integrates personal innovativeness and perceived risk in the TAM model and explores the interrelationships among those constructs. A self-administered questionnaire was used to collect the data for this study, and 293 consumers of the Indonesia Online Travel Agent (OTA) industry participated. The data were analysed using Partial Least Square, which employed the inner and outer model evaluations to analyse the data. The results demonstrated that Generation Z's attitude toward using the OTA application is positively affected by its perceived usefulness and ease of use. Moreover, three variables significantly affect Generation Z's behavioural intention to use e-commerce applications. Personal innovativeness significantly affects perceived transaction risks and attitudes toward using the OTA application. These results imply that in order to enhance customers’ willingness to keep using the application, the OTA practitioners should ensure that their customers experiencing the ease-of-use dan the usefulness of the application, so that the customers will have a greater willingness to use the same application in the future.
