Published: January 2025

Oxazole, a versatile and significant heteroarene, serves as a bridge between synthetic organic chemistry and applications in the medicinal, pharmaceutical, and industrial fields. Polycyclic aromatic compounds with amino groups substituted at the 2-position of an oxazole, such as 2-aminonaphthoxazoles, are expected to be functional probes, but their synthetic methods are extremely limited. Herein, we describe electrochemical reactions of 3-amino-2-naphthol or 3-amino-2-anthracenol and isothiocyanates in DMSO, using a graphite electrode as an anode and a platinum electrode as a cathode in the presence of potassium iodide (KI), which afford N-arylnaphtho- and N-arylanthra[2,3-d]oxazol-2-amines via cyclodesulfurization. This reaction is the first example of synthesis of 2-aminoxazole-based polycyclic compounds using an electrochemical reaction. An examination of the spectroscopic properties of polycyclic oxazoles revealed that the λabs value of the tetracyclic oxazoles was redshifted relative to that of the tricyclic oxazoles. Moreover, synthesized naphthalene/anthracene-fused tricyclic and tetracyclic oxazoles exhibited extended π-conjugated skeletons and fluoresced in the 340–430 nm region in chloroform.

Agomelatine (AGM) is an effective antidepressant with low oral bioavailability due to intensive hepatic metabolism. Transdermal administration of agomelatine may increase its bioavailability and reduce the doses necessary for therapeutic effects. However, transdermal delivery requires crossing the stratum corneum barrier. For this purpose, the use of microneedles may increase the efficiency of administration. The aim of this study was to prepare an agomelatine-loaded hydrogel suitable for coating microneedles for the transdermal drug delivery of AGM. The optimized formulations were subjected to spectroscopic and rheological characterization and mechanical tests, as well as tested for release through an artificial membrane and permeation through human skin ex vivo. Both hydrogels were found to have suitable parameters for coating microneedles using the dip-coating method, including the stability of the substance at the process temperature, shear-thinning behavior, and appropriate textural parameters such as adhesion or hardness. Additionally, two formulations were tested for potential application to the skin alone because the gels showed suitable mechanical properties for the skin application. In this case, the ethanol gel was characterized by higher skin permeability and better spreadability. The information obtained in this study will allow the preparation of coated microneedles for the transdermal administration of agomelatine.

Published: January 2025

In recent years, metal surface plasmon resonance sensors and dielectric guided-mode resonance sensors have attracted the attention of researchers. Metal sensors are sensitive to environmental disturbances but have high optical losses, while dielectric sensors have low losses but limited sensitivity. To overcome these limitations, hybrid resonance sensors that combine the advantages of metal and dielectric were proposed to achieve a high sensitivity and a high Q factor at the same time. In this paper, a hybrid hollow cylindrical tetramer array was designed, and the effects of the hole radius, external radius, height, period, incidence angle, and polarization angle of the hollow cylindrical tetramer array on the refractive index sensing properties were quantitatively analyzed using the finite difference time domain method. It is found that the position of the resonance peaks can be freely tuned in the visible and near-infrared regions, and a sensitivity of up to 542.8 nm/RIU can be achieved, with a Q factor of 1495.1 and a figure of merit of 1103.3 RIU−1. The hybrid metal–dielectric nanostructured array provides a possibility for the realization of high-performance sensing devices.

Published: January 2025

Dental caries remains a prevalent chronic disease driven by dysbiosis in the oral biofilm, with Streptococcus mutans playing a central role in its pathogenesis. Objective: This study aimed to assess the effect of D-tagatose on cariogenic risk by analyzing randomized clinical trials (RCTs). Methods: A systematic literature review was conducted targeting RCTs published up to 2024 in eight databases and two gray literature sources. The search strategy utilized Medical Subject Headings (MeSHs) and relevant keywords combined via Boolean operators using the query “Tagatose OR D-tagatose AND Dental Caries”. Eligible studies must evaluate the impact of D-tagatose on cariogenic risk, as indicated by reductions in colony-forming units (CFUs) and improvements in salivary pH levels in treatment groups. Results: From 1139 retrieved records, three studies met the inclusion criteria. These studies consistently demonstrated significant reductions in CFU counts and improvements in salivary pH levels in groups treated with D-tagatose compared to controls using other non-caloric sweeteners or placebos (p < 0.01). However, the quality of the evidence was heterogeneous, with certain methodological concerns. Conclusions: Although the findings suggest potential benefits of D-tagatose in reducing cariogenic risk, limitations such as small sample sizes and variability in study methodologies warrant caution. Further robust investigations are needed to substantiate these promising results and support the integration of D-tagatose into oral care formulations aimed at reducing cariogenic risk.

Published: January 2025

The COVID-19 pandemic was a risky period for childhood obesity, due to the increase in unhealthy behaviors. Online interventions could prevent this problem. The aim of this study was to evaluate the feasibility and explore the effect of an online program on the BMI z-score of Mexican schoolchildren at 4 months during the pandemic. A pilot randomized controlled trial was conducted with 54 children. The intervention included three online sessions per week of nutrition and physical activity, as well as nutrition information for parents during 4 months. The control group received one nutrition digital brochure. Of the schoolchildren enrolled, 87% completed the study, and the intervention group attended 46% of the classes. At the end of the intervention, no significant difference between groups in the BMI z-score was observed (−0.02, 95% CI −0.19 to 0.15). However, the intervention group improved their quality of life and daily fruit consumption. This online intervention implemented during the COVID-19 pandemic was feasible, and the exploratory analysis showed positive trends in quality of life and daily fruit consumption but not in the BMI z-score and other secondary variables of Mexican schoolchildren. Additional strategies may be needed to improve attendance in online interventions and their impact on BMI in this age group.
Hybrid Nanocomposite Mini-Tablet to Be Applied into the Post-Extraction Socket: Matching the Potentialities of Resveratrol-Loaded Lipid Nanoparticles and Hydroxyapatite to Promote Alveolar Wound Healing

Published: January 2025

Background/Objectives: Following tooth extraction, resveratrol (RSV) can support healing by reducing inflammation and microbial risks, though its poor solubility limits its effectiveness. This study aims to develop a solid nanocomposite by embedding RSV in lipid nanoparticles (mLNP) within a hydrophilic matrix, to the scope of improving local delivery and enhancing healing. Hydroxyapatite (HXA), often used as a bone substitute, was added to prevent post-extraction alveolus volume reduction. Methods: The mLNP-RSV dispersion was mixed with seven different polymers in various mLNP/polymer ratios. Following freeze-drying, the powders were redispersed, and the resulting dispersions were tested by DLS experiments. Then, the best two nanocomposites underwent extensive characterization by SEM, XRD, FTIR, Raman spectroscopy, and thermal analysis as well as in vitro partitioning studies aimed at verifying their ability to yield the mLNP-RSV from the hydrophilic matrix to a lipophilic tissue. The characterizations led to identify the best nanocomposite, which was further combined with HXA to obtain hybrid nanocomposites, further evaluated as pharmaceutical powders or in form of mini-tablets. Results: PEG-based nanocomposites emerged as optimal and, following HXA insertion, the resulting powders revealed adequate bulk properties, making them useful as a pharmaceutical intermediate to produce ≈59 mm3 mini-tablets, compliant with the post-extraction socket. Moreover, they were proven ex vivo to be able to promote RSV and GA accumulation into the buccal tissue over time. Conclusions: The here-proposed mini-tablet offers an innovative therapeutic approach for alveolar wound healing promotion as they led to a standardized dose administration, while being handy and stable in terms of physical solid identity as long as it takes to suture the wound.

Finnish North Karelia is a region with a rich cultural history of ethnomedicinal plant use, shaped by centuries of interactions among various ethnic groups. This study identified both similarities and divergences between local Finns, Karelians war refugees, and individuals of mixed origin compared to historical records. Based on 67 semi-structured interviews, we documented the use of 43 medicinal plant taxa from 25 families, of which 31 remain in use. Notably, the number of medicinal plants continuously used in North Karelia is considerably lower than in other parts of Europe, with less than 25% of historically utilised species still in practice, which reflects the fragile state of this knowledge. Factors such as forced relocation, the loss of traditional lands, and the need to adapt to new environments might have contributed to this decline. Another influencing factor is official healthcare attitudes, which have prompted Finnish residents to shift from traditional herbal remedies to modern medical practices. Understanding the circulation of ethnomedicinal knowledge and its transformation over time is essential for identifying pathways to revitalise these practices within the framework of modern healthcare systems and cultural revitalisation efforts.
Adsorption and Bulk Assembly of Quaternized Hydroxyethylcellulose–Anionic Surfactant Complexes on Negatively Charged Substrates
Authors: Nivard Maud , Ortega Francisco , Rubio Ramón G. , Guzmán Eduardo
Published: January 2025

This study examines the adsorption and bulk assembly behaviour of quaternized hydroxyethylcellulose ethoxylate (QHECE)–sodium dodecyl sulphate (SDS) complexes on negatively charged substrates. Due to its quaternized structure, QHECE, which is used in several industries, including cosmetics, exhibits enhanced electrostatic interactions. The phase behaviour and adsorption mechanisms of QHECE–SDS complexes are investigated using model substrates that mimic the wettability and surface charge of damaged hair fibres. Two preparation methodologies, high-concentration mixing and gradient-free mixing, were employed to examine their impact on the complex equilibrium, phase behaviour, and adsorption properties of the complexes. The measurements of turbidity, electrophoretic mobility, and conductivity demonstrate the existence of nonequilibrium dynamics during the mixing process, which exert a significant influence on the structural and functional characteristics of the complexes. The quartz crystal microbalance with dissipation monitoring (QCM-D) was employed to investigate the adsorption of the complexes onto the substrates. The results demonstrated the critical role of intermediate SDS concentrations in enhancing deposition. The findings emphasise the importance of formulation and preparation protocols in designing stable, high-performance cosmetic products. This research advances our understanding of polyelectrolyte–surfactant interactions and provides insights into optimising QHECE-based formulations.

Published: January 2025

Analysis of the temporal relationship between meteorological drought and hydrological drought is crucial in monitoring water resource availability. This study examined the linear and lagged relationships of the spread of meteorological drought to hydrological drought and their joint effects on low-flow drought variability in the Oum Er-Rbia (OER) watershed. To this end, random forest (RF) model and statistical methods were used to study the characteristics of the temporal relationships between meteorological and hydrological drought indices at monthly, seasonal, and annual scales. The various analyses revealed that the relationship between hydrological and meteorological drought is mainly a function of the time scale considered, the choice of indices to describe each type of drought and the season considered. The hydrological drought of surface water and snow cover is synchronized with the meteorological drought at the monthly, seasonal, and annual scales. In contrast, the transition from meteorological drought to groundwater drought has a lag time of 1 month and is statistically significant up to t − 5 and t + 5, i.e., 6 months. The linear correlation between the annual rainfall deficit and the monthly groundwater storage index was the lowest (0.15) in December and the highest (0.83) in March. This suggests a seasonal response of groundwater drought to the cumulative effects of precipitation deficits. The RF analysis highlighted the importance of the cumulative characteristics of meteorological drought regarding the severity of low-flow drought. The meteorological drought indices at longer time scales have a greater impact on the severity of low-flow drought, with a contribution of approximately 10% per index. However, the relative contributions of meteorological factors and hydrological indices rarely exceed 5%. Thus, by exploring for the first time the complex interactions among the severity of low-flow regimes, meteorological and hydrological drought indices and meteorological factors, this study provides a new perspective for understanding the characteristics of propagation from meteorological to severe hydrological drought.

Published: January 2025

The extensive peatlands of the Tibetan Plateau (TP) play a vital role in sustaining the global ecological balance. However, the distribution of peatlands across this region and the related environmental factors remain poorly understood. To address this issue, we created a high-resolution (10 m) map for peatland distribution in the TP region using 6146 Sentinel-1 and 23,730 Sentinel-2 images obtained through the Google Earth Engine platform in 2023. We employed a random forest algorithm that integrated spatiotemporal features with field training samples. The overall accuracy of the peatland distribution map produced is high, at 86.33%. According to the classification results, the total area of peatlands on the TP is 57,671.55 km2, and they are predominantly located in the northeast and southwest, particularly in the Zoige Protected Area. The classification primarily relied on the NDVI, NDWI, and RVI, while the DVI and MNDWI were also used in peatland mapping. B11, B12, NDWI, RVI, NDVI, and slope are the most significant features for peatland mapping, while roughness, correlation, entropy, and ASM have relatively slight significance. The methodology and peatland map developed in this work will enhance the conservation and management of peatlands on the TP while informing policy decisions and supporting sustainable development assessments.
Three-Dimensional Non-Uniform Sampled Data Visualization from Multibeam Echosounder Systems for Underwater Imaging and Environmental Monitoring
Authors: Cao Wenjing , Fang Shiliang , Zhu Chuanqi , Feng Miao , Zhou Yifan , Cao Hongli
Published: January 2025

This paper proposes a method for visualizing three-dimensional non-uniformly sampled data from multibeam echosounder systems (MBESs), aimed at addressing the requirements of monitoring complex and dynamic underwater flow fields. To tackle the challenges associated with spatially non-uniform sampling, the proposed method employs linear interpolation along the radial direction and arc length weighted interpolation in the beam direction. This approach ensures consistent resolution of three-dimensional data across the same dimension. Additionally, an opacity transfer function is generated to enhance the visualization performance of the ray casting algorithm. This function leverages data values and gradient information, including the first and second directional derivatives, to suppress the rendering of background and non-interest regions while emphasizing target areas and boundary features. The simulation and experimental results demonstrate that, compared to conventional two-dimensional beam images and three-dimensional images, the proposed algorithm provides a more intuitive and accurate representation of three-dimensional data, offering significant support for the observation and analysis of spatial flow field characteristics.
Research on the Classification of Traditional Building Materials in Southern Fujian Using the Reflection Intensity Values of Ground-Based LiDAR
Authors: Wu Tsung-Chiang , Kuan Neng-Gang , Lu Wei-Cheng
Published: January 2025

Ground-based LiDAR technology has been widely applied in various fields for acquiring 3D point cloud data, including spatial coordinates, digital color information, and laser reflectance intensities (I-values). These datasets preserve the digital information of scanned objects, supporting value-added applications. However, raw point cloud data visually represent spatial features but lack attribute information, posing challenges for automated object classification and effective management. Commercial software primarily relies on manual classification, which is time-intensive. This study addresses these challenges by using the laser reflectance intensity (I-value) for automated classification. Boxplot theory is applied to calibrate the data, remove noise, and establish polynomial regression equations correlating intensity with scanning distances. These equations serve as attribute functions for classifying datasets. Focusing on materials in traditional Minnan architecture on Kinmen Island, controlled indoor experiments and outdoor case studies validate the approach. The results show classification accuracies of 74% for wood, 98% for stone, and 93% for brick, demonstrating this method’s effectiveness in enhancing point cloud data applications and management.

Published: January 2025

In 2022, the federal government initiated two grant programs geared to enhance education specifically for Afghan and Ukrainian populations: the Afghan Refugee School Impact and Support to Schools supplements, both part of the Refugee School Impact (RSI) program. In Missouri, the context of our research, RSI funding has been coordinated by a non-profit organization, the Missouri Office for Refugee Administration (MO-ORA). In partnership with MO-ORA, we designed a qualitative study and used content analysis to examine 39 RSI grant applications to MO-ORA from 35 different districts. We explored two key research questions: (1) what did K-12 schools in Missouri identify as priorities to support refugee students in their RSI grant applications? and (2) how did districts plan to allocate resources to meet refugee students’ and families’ perceived needs? Analyses identified that districts’ biggest priorities were to support: (1) family engagement activities, (2) English Learners’ education, and (3) student English language proficiency. Meanwhile, districts’ top three areas of funding allocation went to the pre-named categories of Student Services for Els, Professional Development for Staff, and Facilitating Partnerships.

Published: January 2025

In this paper, we propose a weighted Lindley (NWLi) model for the analysis of extreme historical insurance claims. It extends the classical Lindley distribution by incorporating a weight parameter, enabling more flexibility in modeling insurance claim severity. We provide a comprehensive theoretical overview of the new model and explore two practical applications. First, we investigate the mean-of-order P (MOOP(P)) approach for quantifying the expected claim severity based on the NWLi model. Second, we implement a peaks over a random threshold (PORT) analysis using the value-at-risk metric to assess extreme claim occurrences under the new model. Further, we provide a simulation study to evaluate the accuracy of the estimators under various methods. The proposed model and its applications provide a versatile tool for actuaries and risk analysts to analyze and predict extreme insurance claim severity, offering insights into risk management and decision-making within the insurance industry.
Chiral Effective Model of Cold and Dense Two-Color QCD: The Linear Sigma Model Approach
Authors: Suenaga Daiki
Published: January 2025

This review is devoted to summarizing recent developments of the linear sigma model (LSM) in cold and dense two-color QCD (QC2D), in which lattice simulations are straightforwardly applicable thanks to the disappearance of the sign problem. In QC2D, both theoretical and numerical studies derive the presence of the so-called baryon superfluid phase at a sufficiently large chemical potential (μq), where diquark condensates govern the ground state. The hadron mass spectrum simulated in this phase shows that the mass of an iso-singlet (I=0) and 0− state is remarkably reduced, but such a mode cannot be described by the chiral perturbation theory. Motivated by this fact, I have invented a LSM constructed upon the linear representation of chiral symmetry, more precisely Pauli–Gürsey symmetry. It is shown that my LSM successfully reproduces the low-lying hadron mass spectrum in a broad range of μq simulated on the lattice. As applications of the LSM, topological susceptibility and sound velocity in cold and dense QC2D are evaluated to compare with the lattice results. Additionally, the generalized Gell–Mann–Oakes–Renner relation and hardon mass spectrum in the presence of a diquark source are analyzed. I also introduce an extended version of the LSM incorporating spin-1 hadrons.

Sources, Water Quality, and Potential Risk Assessment of Heavy Metal Contamination in Typical Megacity River: Insights from Monte Carlo Simulation
Authors: Gao Xi , Han Guilin , Zhang Shitong , Zeng Jie
Published: January 2025

Due to the intense human activities and rapid development of economy, dissolved heavy metals (DHMs) pose a significant threat to urban river ecosystems. Therefore, the distribution, sources, and potential risks of DHMs in the Chaobai River (typical urban river) were investigated via ICP-MS in detail. Results revealed considerable spatial heterogeneity of heavy metals with various concentrations from the upper to lower reach. Principal component analysis (PCA) revealed that V, Ni, As, Mo, and Pb mainly originated from a mixing process of industrial input and natural process, Cr and Cu were mainly derived from urban activities, and Zn was mainly influenced by agriculture activities. Furthermore, land use types within the buffer zone near sampling points were innovatively analyzed, revealing strong correlations between DHMs and regional land use patterns. Monte Carlo simulations were employed to assess the differentiated non-carcinogenic and carcinogenic risks associated with DHMs across four age groups. This study provided scientific references for the sustainable management of urban rivers and aquatic systems in such a megacity region.

Published: January 2025

As aves são seres dotados de peculiaridades físicas, sonoras e comportamentais, e estes aspectos despertam vínculos afetivos, curiosidade e engajamento. O turismo de observação de aves cresce cada vez mais no território nacional, e no estado do Rio de Janeiro não é diferente. Teresópolis, município localizado na região serrana, está entre os principais roteiros dos observadores de aves do RJ, e isso se dá pelo fato de estar em meio à Serra dos Órgãos e cercada por três Parques, sendo um deles o Parque Natural Municipal Montanhas de Teresópolis-PNMMT. Atualmente o PNMMT vem investindo na implementação de um roteiro de observação de aves juntamente com infraestrutura adaptada a esta atividade. O objetivo deste artigo é destacar as principais experiências, motivações e investimentos do PNMMT para o desenvolvimento da observação de aves considerando os seguintes fatores: as primeiras ações da observação no Parque; a construção do roteiro de observação de aves e; o desenvolvimento do Vem Passarinhar. Essas experiências são discutidas a partir das relações entre a gestão e os produtores rurais da região de Santa Rita, que desenvolvem territorialidades socioambientais específicas. Este trabalho se baseia na experiência direta dos autores na concepção e implementação do roteiro, além da análise das diversas fontes documentais utilizadas e desenvolvidas ao longo do processo. Quanto as primeiras ações que impulsionam o Parque na implementação da observação de aves, a publicação do livro comemorativo Admiraves foi o principal documento que reunia à época as espécies de aves da UC. Foi verificado que, a partir da estruturação do setor de biodiversidade, o incentivo da observação de aves foi despertado, principalmente a partir da criação do roteiro de observação de aves. Além disso, o investimento em infraestrutura, como torre de observação de aves e um observatório na margem do lago natural, foram fundamentais para impulsionar as atividades de observação. A implementação do Vem Passarinhar nas Montanhas de Teresópolis possibilitou que observadores de todos os perfis conhecessem a unidade de conservação. Verificou-se, também, a partir das práticas e intervenções desenvolvidas pelos gestores e autores desta pesquisa, que, apesar das tensões que são próprias da relação entre gestores e agentes do território, os serviços turísticos de apoio à observação de aves têm se fortalecido e as iniciativas institucionais estão possibilitando a formação de redes de cooperação para o turismo, o que permite a valorização e envolvimento das territorialidades socioambientais aliadas à conservação da avifauna local através da ciência-cidadã.

Determination of gender dimorphism of the morphometric indicators of the human orbit depending on the craniotype
Authors: Melnyk B.I.
Published: January 2025

The issue of studying sexual dimorphism of skull structures depending on the craniotype remains relevant. The purpose was to study the morphometric parameters of the human orbit depending on the craniotype and gender. The study was conducted on 125 computed tomography scans of people's heads aged 25 to 85 years, performed using a computer tomography Neusoft, NeuViz 16 Essence 16-Slice CT Scanner System (Neusoft Medical Sytems Co, USA). Craniometric measurements were performed using programs Horos, ver. 4.0.1 (Neusoft Medical Sytems Co, USA) and RadiAnt Dicom Viewer, ver. 2024.1 (Medixant, Poland). The study was conducted with a slice thickness of 1.5 mm, followed by reconstruction in three planes. The basic facial index was calculated using the Garson-Kolman formula. It has been established that the height, width, perimeter, area, and conditional radius of the orbital opening of male euriprosopes are significantly different from similar indicators of females. In mesoprosopes, only the height of the orbital opening of men and women has a reliably significant difference. No statistically significant difference in the above indicators between representatives of different sexes was found in leptoprosops. No statistically significant differences in arithmetic mean values of the investigated indicators of the right and left eye sockets, as well as persons of different age groups, were found. According to the orbital index, all research objects were divided into 3 groups: khameconchs, mesoconchs, hypsiconchs. It has been established that the majority of both males and females belong to hypsiconchs, mesoconchs occupy an intermediate position, and the smallest group is khameconchs. The most widespread groups are hypsiconchs with euryprosopic facial skull shape and hypsiconchs with mesoprosopic shape.

Keywords: skull, morphometry, orbital index, orbital opening.

Published: January 2025

Nowadays, a variety of techniques exist for mitigating the effects of corrosion, including the use of anticorrosive
coatings. In this study, we investigate the impact of viscosity on the final quality of a silica/PDMS-based ceramic
coating, synthesized through sol-gel methodology. The polycondensation of tetraethylorthosilicate (TEOS) with
polydimethylsiloxane (PDMS) was conducted at concentrations of 10, 20, and 40 wt.%, employing DBTL as a
catalyst. The coatings were deposited on Al-6061 surfaces via immersion. Infrared spectroscopy indicates the
integration of the inorganic phase (SiO₂; 1100 cm⁻¹, 720 cm⁻¹) with the siloxane chain (PDMS; 2900 cm⁻¹, 1250
cm⁻¹, 920 cm⁻¹, 785 cm⁻¹). As the siloxane chain length increased, modifications to the silica structure were
observed, with the appearance of signals at 889 cm-1, 867 cm-1, and 835 cm-1. Conversely, the gelation times are
reduced in proportion to the PDMS content in the sol solution. Therefore, to obtain smooth and homogeneous
finishes, different gelation times are required when applying solutions with viscosities between 5 and 12 mPa·s.
These coatings exhibited the most significant increase in corrosion resistance, reaching approximately 75%.

Published: January 2025

The advent of Mobile-Assisted Language Learning (MALL) has revolutionized the field of English as a Foreign Language (EFL) education by providing learners with unprecedented access to language learning resources anytime and anywhere. Among the various skills in language acquisition, listening is often considered one of the most challenging to master. Therefore, it is important to implement effective strategies to enhance listening comprehension. This study examined the role of cognitive strategies in enhancing EFL listening abilities among learners by using MALL, with the aim to investigate what cognitive strategies students used during their listening practice with the MALL method. The qualitative research method was adopted and the students’ listening journals were collected and analyzed by using the thematic analysis to conduct the research. Results of the study indicated that meta-cognitive, cognitive, and social-affective strategies were used in students’ listening practice. Some other useful points were also found to guide the future MALL research in EFL listening practice. The findings are expected to provide insights for effectively incorporating cognitive strategies with MALL method in EFL listening studies so as to improve listening efficiency and inform instructional practices in the EFL classroom.

The hybrid synchronization of tangible military logistics provides the formulae for military preparedness in anticipation of combat duties common for militaries globally. The military combat readiness is formulated with a mathematical formula for the tangible military logistics requirements at all times. Situational Forces Scoring (SFS) provides the quantitative numerical measurement for military combat readiness preparedness in anticipation for operational duties in logistics and manpower planning. In addition to identifying and measuring the intangible human components of soldiers in the areas of morale, quality of life, and military psychological aspects, this study will consists of four antecedents for each domain. This quantitative research was conducted with 2466 military personnels working in operational areas throughout Malaysia. PLS-SEM provided the statistical validation of the model with the data (n = 2466). The outcomes of the statistical analysis shows that the R2 value of 62.9% of intangible human elements is explained by exogenous variables of morale, quality of life, and psychological. Results indicate that morale (β= 0.578) has the highest direct effect on the measure of combat readiness as compared to psychological (β= 0.171) and quality of life (β= 0.091). The morale variable of soldiers provides the platform for high performance in combat duties. The results of this research indicate that the morale of soldiers must be consistently reinforced so that individual soldiers provide the dimensions for collectively team performance in the Malaysian Armed Forces during combat duties. Efforts to effectively improve quality of life and psychological problems should also be emphasized with greater emphasis on improving overall unseen combat readiness. Many defence and security agencies will benefit from this research as they can adopt this research model for their operational prepardness and readiness in their organizations.

Assessment plays an essential role in learning and must be designed to measure the student's learning and align with the intended learning outcomes. Prior to the pandemic, most of the assessments were performed face-to-face. However, during the pandemic, the assessment could not be conducted as face-to-face activities, which caused challenges to the assessment that required face-to-face implementation. This study seeks to critically examine the implementation of the online assessment conducted during the COVID-19 pandemic to assess the psychomotor learning domain. The study used a qualitative case study that utilized document analysis and interview protocol. Purposive sampling was adopted, and the sample population consists of 60 students taking the course during the March – July 2020 semester. The data collection procedure was separated into Stages 1 and 2, Document Analysis and Semi-structured in-depth interviews analyzed using thematic analysis. The findings show that certain conducted assessments are unsuitable for assessing the psychomotor learning domain due to the nature of the assessment and the criteria adopted to assess the students. It is suggested that the implementation of assessment in assessing students' psychomotor skills through online be re-examined. This study also found that the students had to face four main challenges in conducting the online assessment that could affect the students’ performance: internet connectivity, accessibility to a decent device to complete the assessment, lack of explanation on the assessment and the environment while conducting the assessment.
