Published: February 2025

This study explores the process of design and optimization of exoskeleton for lower
extremities using methods of generative design. Due to the unique characteristics and features of the
human body, every exoskeleton needs to be adjusted to the working condition of each user, but the
development of individual product designs by engineers is highly expensive and takes a lot of time.
The study objective is the optimization of the base model of the exoskeleton to working conditions
using generative design technology. Optimization is based on human movements and biomechanics,
especially on joint torque, which allows to design of construction with acceptable safety factors.
Results show highly optimized designs for different materials and a significant reduction in mass
and volume relative to the base model. Usage of such technologies saves development time,
allowing engineers to focus on more complex aspects of design.

A new computer program (CP) has been created as a website for ATX classification
groups to search for lists of medicinal products (MPs) as potential candidates for import substitution.
The development of the CP with the conditional name ―Computer Program for Import Substitution
of Medicines‖ (CPISM) was carried out using open databases, which are regulated by the regulatory
legal acts of the pharmaceutical industry of Ukraine. CPISM helps to quickly find lists of necessary
medicinal products (MPs) subject to import substitution since these medicines are represented only
by imported drugs in the Ukrainian pharmaceutical market. Using the CPISM website, you can
obtain a list of pharmacological groups of MPs that require import substitution, which is especially
important in martial law conditions. The production of these drugs can be implemented in domestic
pharmaceutical enterprises. The advantages of the CPISM website, compared to other similar search
programs, are the use and processing of 3 main drug databases with a convenient presentation: The
State Register of Medicinal Products of Ukraine, the National List of Essential Medicinal Products,
and the Register of Wholesale Prices of Manufacturers of Medicinal Products. This also allows
searching for drugs by international non-proprietary names in all dosage forms with different
dosages. CPISM is implemented as a web page and adapted for various devices. The architecture of
the developed CPISM website is built based on a modular monolith. The web part and the data
processing program are written in C++. The web part is implemented using the Drogon framework,
providing an ORM for working with MySQL.

Problem statement. Ensuring precise and convenient control of mobile platforms
through a discrete joystick is a current challenge in modern automation systems. One of the primary
issues is the uneven sensitivity of the joystick in different directions due to the heterogeneous
distribution of the areas of its virtual field segments. Purpose. The aim is to develop and optimize a
methodology for balancing the areas of virtual field segments of the discrete joystick in rectangular,
diagonal, and polar coordinate systems to ensure uniform control sensitivity. Methodology. The
study is based on the use of analytical methods for determining the areas of virtual field segments
for three coordinate systems. A geometric transformation method was applied to derive area
formulas. The analysis took into account the conditions for equalizing the areas of the central, axial,
and diagonal groups of segments. Graphs of the dependence of segment areas on the parameter
determining the size of the central segment were obtained. Findings. Analytical formulas for
determining the areas of virtual field segments in three coordinate systems are proposed. Conditions
for balancing the areas of segments for different groups are established, enabling uniform sensitivity
or adaptation for specific control tasks. The optimal parameter values for achieving balance in each
coordinate system are identified. Originality. This work presents, for the first time, a methodology
for analytically balancing the areas of joystick virtual field segments in various coordinate systems.
A mathematical model accounting for the geometry of the segments in rectangular, diagonal, and
polar coordinate systems is developed. Practical value. The results of this study allow for adjusting
joystick parameters based on mobile platform control tasks. This contributes to improved precision,
reduced control errors, and adaptation of the joystick to operator needs in various operational
conditions. Scopes of further investigations. Further research may focus on the development of
adaptive algorithms for real-time joystick parameter adjustments. Another promising direction is to
incorporate the dynamic characteristics of mobile platforms and test the proposed models in practical conditions

The constant growth of data volumes requires the development of effective
methods for managing, processing, and storing information. Additionally, it is advisable to apply
multimodal approaches for knowledge aggregation to extract additional knowledge. Usually, the
problem of efficient processing of multimodal data is associated with high-quality data

preprocessing. One of the most critical preprocessing steps is synchronizing multimodal data stre-
ams to analyze complex interactions in different data types. In this article, we evaluate existing

approaches to synchronization, focusing on strategies based on real-time classifiers, which are based
on comprehensive platforms for data integration and management. After the synchronization of
multimodal sets, the key stage is data fusion, data identification in different channels, such as text,
video, and audio. The results demonstrate the feasibility of the proposed synchronization approach
for revealing subtle relationships between various data sets. An architectural solution was also
suggested to integrate the proposed method into existing multimodal data processing pipelines. This
work contributes to developing synchronization tools for multimodal data analysis in dynamic real-
world scenarios.

Published: February 2025

This study investigates the process of 3D printing a model with several types of
filament at different percentages of material moisture. Due to the unique characteristics of individual
plastics, each print requires preliminary setup of both the printer and the printing process, it is also
important to prepare the appropriate material. Neglecting at least one of these nuances will lead to an
incorrect printing process and, as a result, a deterioration in the quality of the part. The purpose of
the study is to determine the value of the percentage of moisture content in the most common types
of filament under the condition of high-quality printing, by comparing physical objects printed under
different conditions and at different material moisture. An exoskeleton vertebra model was chosen as
a test object. The result shows a significant improvement in quality when observing the correct
filament moisture requirements and adjusting the printing process accordingly for each plastic.

This paper focuses on the quality assurance culture in a college in a multicultural setting. Its purpose is to explore the role of higher education leaders in creating a culture of quality assurance practices in a multicultural environment. The external stakeholders’ perceived value of the institution has been declining over the past ten years, and it is unknown if the lack of a common culture of quality assurance practices within the institution contributes to its decline. The overarching research question is, how do educational leaders create a culture of quality assurance practice and standards in a multicultural environment to improve the perceived value of the institution? The qualitative approach to this research engaged a single case study design. Data was collected using semi-structured interviews, observation, and document review. The data were analysed using manual coding that extracted themes such as the need for a curriculum committee and the creation of policy documents. The conceptual framework outlined the concepts and theories that contributed to the analysis and discussion of the findings. The literature reviewed addressed the use of Hofstede’s six-dimension framework in determining the current culture in the institution and the ISO-9001 quality management system’s application in the multicultural setting. The findings of the research were that the college lacked a common culture of quality assurance. Participants believed that adapting a quality control model would improve the perceived value of the institution and that the leader played a critical role in creating a culture of quality assurance practices.

Published: February 2025

Introduction: Preeclampsia (PE) is a major cause of maternal morbidity and mortality, particularly in low-resource settings. Although Magnesium Sulfate (MgSO4) is the standard treatment for preventing eclampsia, its precise effects on vascular function, especially regarding Endothelin-1 (ET-1) levels, remain unclear. ET-1, a potent vasoconstrictor, is elevated in hypertensive disorders of pregnancy, contributing to endothelial dysfunction in PE. This study aims to investigate the impact of MgSO4 therapy on plasma ET-1 levels in pregnant women diagnosed with severe PE.
Method: This observational follow-up study was conducted at RSUP Prof. Dr. I. G. N. G. Ngoerah, Denpasar, starting in October 2022. Participants included pregnant women with severe PE, aged 20–40 weeks of gestation, receiving MgSO4 therapy. Patients with chronic conditions such as diabetes or pre-existing hypertension were excluded. Blood samples were collected before and after MgSO4 administration, and plasma ET-1 levels were measured using enzyme-linked immunosorbent assay (ELISA). Statistical analysis was conducted using the Wilcoxon test, with a significance level set at p < 0.05.
Results: A total of 31 participants, with a mean age of 32.09 ± 6.48 years, were included. Most patients were nulliparous (32.3%) and had a single marriage history (71.0%). Baseline characteristics showed high systolic and diastolic blood pressures (mean 165 and 110 mmHg, respectively), elevated MAP (131 mmHg), and significant proteinuria (+3 in 38.7% of cases). Laboratory results indicated abnormal levels of AST, ALT, LDH, and creatinine, with an average platelet count of 241.35 ± 69.77 x 103/L. Following MgSO4 therapy, ET-1 levels significantly decreased from a median of 12.45 ng/mL to 5.55 ng/mL (p = 0.004), suggesting an improvement in endothelial function.
Conclusion: The study findings suggest that MgSO4 not only prevents seizures but also plays a role in reducing vasoconstriction in PE patients through the modulation of ET-1 levels. This supports the potential use of ET-1 as a marker to evaluate the therapeutic efficacy of MgSO4 in PE management, highlighting MgSO4’s broader vascular benefits in treating PE.

Authors: Suparman Suparman , Juandi Dadang , Turmudi Turmudi
Published: February 2025

In the last ten years, there has been considerable growth in empirical studies examining the effects of digital games on mathematics learning and computational thinking (CT). However, a review of the existing literature indicates that the outcomes of digital game-enhanced math instruction on students' CT skills have yielded inconsistent results. This research intends to evaluate how effective digital game-supported mathematics education is in developing students' CT abilities, while taking into account various factors such as educational level, duration of the intervention, learning context, game developer, and type of game. A meta-analytic review was conducted, analyzing 15 pertinent studies published between 2011 and 2023, which produced 21 effect sizes and included a total of 8,911 students. Statistical analyses, including the Q Cochrane test, publication bias assessment, Z test, and sensitivity analyses, were performed using CMA software to scrutinize the data. The results indicated a statistically significant but modest positive effect (g = 0.344; p < 0.05) of digital game-supported math education on students' CT skills. Several factors, including the length of the intervention, the software developer, and the type of game, significantly impacted CT outcomes, whereas other factors, such as educational level and learning environment, did not show a significant influence. These findings suggest that digital game-supported mathematics instruction can be an effective technological approach to enhance students' computational thinking abilities.

Published: February 2025

It is crucial to communicate using a language. However, a lot of EFL students had trouble expressing their ideas. 25 freshmen joined the therapy to make it better. To improve the effectiveness of the teaching-learning process, the teacher created a WhatsApp group application during pre-learning. The instructor guided the pupils in creating sentences by teaching them the lexico-grammar of bilingualism. The teacher displayed the podcast's URL on the screen to help students coordinate their contextual usage. Using this kind of content, the students improved their noticing, listening, repeating, shadowing, and translating skills. It is the audio and video version of the podcast. The pupils must improve their capacity for information exchange. In order to appease them, the instructor displayed the URL of an online drama script on the screen. The pupils rehearsed the role play in order to finish the assignment. The study's results were then qualitatively examined. As a result of using podcasts and online theatrical scripts to study speaking, the students' capacity for presenting ideas increased. The novelty is this approach leverages the power of multimedia to create an engaging and authentic learning experience that goes beyond traditional classroom activities. Teachers must use these kinds of findings when instructing related subjects. It also encourages other researchers to carry out studies in related disciplines.

Authors: Shaikh Hasan , Hossen Md. Iqbal
Published: February 2025

In an era where educational reforms serve as both a beacon of hope and a source of contention, the New Education Policy (NEP) of Bangladesh emerges as a critical site for exploring the dynamic interplay between policy ideals and classroom realities. Grounded in the Theory of Planned Behavior, it seeks to examine teachers’ interpretations and responses to policy reforms, their challenges and opportunities, and the impact of the NEP on education quality. The study employs a mixed-methods approach, combining a survey of 48 teachers from seven distinct schools, with nine providing in-depth interviews. The findings reveal significant discrepancies in teachers’ understanding of the policy’s objectives, with a notable portion expressing dissatisfaction with its clarity and alignment with student needs. While some educators acknowledge a shift towards student-centered learning, others highlight the obstacles posed by insufficient resources, professional development, and curriculum adjustments. However, to address the limitations of this study, future studies can expand the scope to include different regions and explore the long-term effects of NEP on student outcomes. Furthermore, educators and policymakers must collaborate to ensure that ongoing professional development and resource allocation are prioritized to facilitate successful educational reform.

Kangkung (Ipomoea reptans Poir) merupakan salah satu sayuran daun yang banyak digemari masyarakat karena kandungan gizi tinggi. Peningkatan kebutuhan kangkung perlu diikuti dengan peningkatan produksinya. Salah satu cara peningkatan produksi kangkung dapat dilakukan dengan perluasan area budidaya. Pemanfaatan areal dengan intesitas cahaya yang minim seperti di antara tanaman tahunan atau pekarangan di kawasan urban dapat menjadi alternative tempat budidaya tanaman kangkung. Tujuan penelitian ini yaitu untuk mengetahui tingkat toleransi tanaman kangkung terhadap naungan dan menentukan varietas kangkung yang toleran terhadap kondisi cahaya minimum. Penelitian dilaksanakan di lahan percobaan Desa Permata Baru (104º46’44”E; 3º01’35”S) Kabupaten Ogan Ilir Sumatera Selatan dengan mengunakan naungan artificial pada bulan Juli hingga September 2023. Penelitian ini menggunakan rancangan petak terbagi dengan 2 faktor. Taraf naungan sebagai petak utama terdiri dari 0% (tanpa naungan), 55%, 70% dan 95%. Varietas sebagai anak petak terdiri dari varietas Bangkok LP-1 dan varietas Bika. Hasil penelitian menunjukkan bahwa dengan menurunnya intensitas cahaya matahari akan menurunkan pertumbuhan tanaman kangkung. Naungan 55% menurunkan secara signifikan pertumbuhan dan hasil kangkung, semakin bertambahnya tingkat naungan maka semakin menekan pertumbuhan kangkung. Varietas Bangkok LP-1 dan varietas Bika tidak terdapat perbedaan baik pertumbuhan maupun hasil.

Tembakau merupakan salah satu komoditas unggulan di Kabupaten Jember dimana 90% produksinya dikirim untuk ekspor. Penelitian ini bertujuan untuk mengetahui strategi peningkatan produktivitas tembakau Besuki Na-Oogst dengan melihat peran aktor dan hubungan antar aktor terhadap pengembangan tembakau Besuki Na-Oogst di Kabupaten Jember. Penelitian dilaksanakan di Kabupaten Jember, Provinsi Jawa Timur sebagai produsen tembakau nomor satu di Jawa Timur. Penelitan ini merupakan jenis penelitian deskriptif kuantitatif. Metode penentuan sampel yang digunakan dalam penelitian ini adalah purposive sampling, sementara itu metode analisis data yang digunakan dalam penelitian ini adalah analisis Mactor (Matrix of Alliances and Conflicts: Tactics, Objectives and Recommendations). Data penelitian merupakan data primer yang diperoleh melalui observasi, wawancara, dan kuesioner. Wawancara dilakukan kepada 25 orang sebagai responden meliputi petani tembakau, bea cukai, Dinas Tanaman Pangan, Hortikultura dan Perkebunan, Dinas Perindustrian dan Perdagangan, perusahaan tembakau, perokok aktif dan pasif, perguruan tinggi, dan Asosiasi Petani Tembakau Indonesia (APTI) yang diambil acak dikarenakan sudah dapat mewakili seluruh populasi. Hasil penelitian ini menunjukkan bahwa Bea Cukai memiliki peranan tinggi dengan ketergantungan yang tinggi yang berarti aktor Bea Cukai merupakan aktor utama yang sangat memengaruhi pengembangan produktivitas perkebunan tembakau namun tidak memiliki akses secara langsung untuk mengembangkan perkebunan tembakau. Aktor petani tembakau dan APTI memiliki peranan tinggi dengan ketergantungan rendah yang artinya aktor ini bisa memengaruhi pengembangan produktivitas perkebunan tembakau dan memiliki akses secara langsung untuk mengembangkan perkebunan tembakau. Oleh karena itu, diperoleh strategi termasuk peningkatan produktivitas tembakau, peningkatkan permintaan tembakau, melakukan peningkatan infrastruktur, melakukan pengembangan dalam penerapan teknologi, peningkatan lapangan pekerjaan, peningkatan persediaan pupuk subsidi; dan pengembangan pasar yang lebih luas atau peluang ekspor.

Peningkatan produksi kopi harus disertai dengan pemeliharaan mutu biji kopi yaitu dengan cara penyimpanan dan pemilihan jenis kemasan yang tepat sehingga dapat mempertahankan mutu biji kopi. Penurunan mutu biji kopi dapat berakibat pada penurunan umur simpannya. Umur simpan biji kopi dapat ditentukan berdasarkan perubahan yang terjadi pada mutu biji kopi selama penyimpanan yaitu dapat dilakukan dengan menggunakan metode Accelerated Shelf-Life Test (ASLT). Penelitian ini bertujuan untuk mengetahui dugaan umur simpan biji kopi arabika dari Sidikalang dengan menggunakan metode ASLT model Arrhenius berdasarkan parameter kadar air. Penelitian ini dilakukan dengan menggunakan empat jenis kemasan, yaitu aluminium foil, Grainpro, kertas, dan goni rami dengan tiga suhu penyimpanan, yaitu 30 °C, 40 °C, dan 50 °C. Hasil penelitian menunjukkan bahwa umur simpan biji kopi dengan kemasan kantong aluminium foil, kantong Grainpro, kantong kertas, dan karung goni adalah 42 hari, 46 hari, 29 hari, dan 28 hari pada suhu 30°C; 20 hari, 21 hari, 15 hari, dan 13 hari pada suhu 40°C; dan 10 hari, 11 hari, 8 hari, dan 6 hari pada suhu 50°C.

Cabai jawa (Piper retrofractum) merupakan tanaman asli Indonesia yang sering disebut juga cabai jamu, memiliki peran penting dalam sektor pertanian dan industri herbal. Tanaman ini terkenal karena buahnya yang memiliki rasa pedas dan khasiat kesehatan, serta digunakan sebagai bahan baku obat tradisional dan produk farmasi. Mengingat potensi ekonomi dan kesehatannya, penting untuk menganalisis daya saing dan dampak kebijakan pemerintah terhadap pengembangan usahatani cabai jawa di Provinsi Lampung. Penelitian ini bertujuan menganalisis daya saing dan dampak kebijakan pemerintah terhadap input-output usahatani cabai jawa di Provinsi Lampung. Metode penelitian yang digunakan ialah survei yang dilakukan di tiga desa berbeda yaitu Desa Sukoharjo III Barat, Kabupaten Pringsewu, Desa Bandar Rejo, Kabupaten Lampung Selatan, dan Desa Bandar Jaya Barat, Kabupaten Lampung Tengah. Responden ditetapkan menggunakan metode purposive sampling dengan total 18 petani cabai Jawa. Data penelitian diperoleh dari bulan September hingga November 2023. Metode analisis yang digunakan ialah metode Policy Analysis Matrix (PAM). Hasil penelitian menunjukkan bahwa usahatani cabai jawa di Provinsi Lampung sudah berdaya saing karena memiliki keunggulan kompetitif dan keunggulan komparatif dengan nilai Private Cost Ratio sebesar 0,41 dan nilai Domestic Resources Cost Ratio sebesar 0,23. Kebijakan pemerintah yang ada berdampak negatif terhadap usahatani cabai jawa di Provinsi Lampung karena menyebabkan petani membayar biaya input tradable lebih mahal dengan keuntungan yang diterima masih jauh lebih rendah daripada yang seharusnya.
