Authors: Syahri Wilda , Yusnaidar Yusnaidar
Published: January 2025

Physical Chemistry II course in the Chemistry Education Study Program is one of the subjects with an abstract nature, such as Electrochemistry materials. The abstract nature of Electrochemistry makes it difficult for students to observe the processes occurring in Electrochemical systems directly. When explained theoretically, these concepts are often challenging for students to understand. Therefore, teaching Electrochemistry requires an e-book that incorporates chemical representations, particularly multiple representations. To address this, it is deemed necessary to develop an Electrochemistry e-book based on multiple representations using 3D PageFlip. This e-book integrates multiple representations, enabling students to independently study and comprehend Electrochemistry materials while providing flexibility and convenience. An Electrochemistry e-book with multiple representations, particularly in a computer-assisted learning format, is a viable alternative to support student learning. This study aims to develop an Electrochemistry e-book using 3D PageFlip based on multiple representations. This software allows the creation of interactive and engaging educational resources. The resulting e-book aims to enhance students' individual abilities and increase their interest and motivation, which in turn is expected to improve their academic performance and learning outcomes. Moreover, this multimedia learning tool is intended to address challenges related to students' limited comprehension during classroom learning processes, accommodate individual characteristics, and offer alternative solutions to the low self-actualization of students. Through this e-book, students can revisit and explore difficult concepts, facilitating deeper understanding. The ultimate goal of this research is to produce an Electrochemistry e-book based on multiple representations across macroscopic, microscopic, and symbolic levels using 3D PageFlip.

Authors: Armas Kenneth L. , Fernandez Khriz N. , Faigal Aileen Vigilia , Garcia-Reyes Alma Pia
Published: January 2025

This exploratory study examines the marketing practices and distribution strategies of an agricultural industry in San Antonio, Nueva Ecija, the Philippines, with a focus on the local broom reed or “tambo”, which holds significant ecological and economic value. The research investigates production methods, marketing strategies, distribution channels, and pricing practices, revealing that small-scale enterprises predominantly use markup pricing and selective distribution. Geographic reach extends beyond San Antonio to neighboring provinces and metropolitan areas, with many producers utilizing their own delivery vehicles and offering free delivery services. However, these enterprises face challenges, including limited access to capital, inadequate marketing infrastructure, and logistical difficulties, which restrict their ability to scale. The findings emphasize the need for sustainable development initiatives and government support to address these constraints and promote growth. This study provides valuable insights into the marketing dynamics of the broom reed sector, offering recommendations for targeted interventions that could improve production efficiency and market reach, ensuring long-term sustainability and economic viability for the industry.

Reevaluating the institutional autonomy of 14th century Mount Athos under the Ottomans: The “confiscation issue” concerning Athonian landholdings in post-Byzantine Macedonia
Authors: Nikopoulos Anastasios
Published: January 2025

The dependances of the monasteries of Mount Athos, from the emergence of the
Athonian monastic community, constituted a unique and particular institution
which had certain legal characteristics; it was recognized by both the
Byzantine and the post-Byzantine legal order and was always respected by
every sovereign in the history of Mount Athos. These features were that they
constituted the property of each monastery, according to its legal type as a
foundation of Byzantine-Roman law; they could come from any legal cause and
be subject to ratification or recognition, directly or indirectly, by an
imperial act and had a privileged character and enjoyed special protection,
rendering them inalienable. The Byzantine institution of monastic dependance
institutionally and historically influenced the development of the kinship
institution of the Ottoman and Islamic vakif, and it is known that the
Ottomans recognized and protected the dependances, especially those of the
Athonite monasteries. The opinions regarding the alleged confiscations of
dependances of Athonian monasteries during the early period of Ottoman rule,
around the end of the 14th century, are incorrect. The study examines in
detail the cases of two dependances of the Zographou monastery in 1392, one
dependance of the Esphigmenou monastery from 1388 and some dependances of
the Vatopedi monastery, based on two documents (from 1404 and 1408) from its
archive.

Published: January 2025

Objectives

To develop facial growth prediction models using artificial intelligence (AI) under various conditions, and to compare performance of these models with each other as well as with the partial least squares (PLS) growth prediction model.

Materials and Methods

Longitudinal lateral cephalograms from 33 subjects in the Mathews growth collection were utilized. A total of 1257 pairs of before and after growth lateral cephalograms were included. In each image, 46 hard and 32 soft tissue landmarks were manually identified. Growth prediction models were constructed using a deep learning method based on TabNet deep neural network and partial least squares (PLS) method. Prediction accuracies of the two methods were compared.

Results

On average, artificial intelligence (AI) showed 0.61 mm less prediction error than PLS. Among the 77 predicted landmarks, AI was more accurate than PLS in 60 landmarks. When comparing AI models with varying numbers of training epochs, those with higher epochs yielded more accurate predictions. Overall, PLS and AI exhibited greater prediction errors for soft tissue and mandibular landmarks compared to hard tissue and maxillary landmarks. However, AI showed a smaller increase in prediction error in areas with greater variability.

Conclusions

AI proved to be a valuable growth prediction method, with clinically acceptable prediction errors averaging 1.49 mm for 45 hard tissue landmarks and 1.71 mm for 32 soft tissue landmarks. PLS accurately predicted landmarks with low variability. However, AI generally outperformed PLS, particularly for landmarks in the lower part of the craniofacial structure and soft tissue, where uncertainty is considerable.

Authors: Kluvers Katla R. , Tryggvason Thordur , Stefansdottir Vigdis , Jonasson Jon G. , Snaebjornsson Petur , Haraldsdottir Sigurdis
Published: January 2025

Background and purpose: Screening for Lynch syndrome (LS) with mismatch repair (MMR) protein immunohistochemistry (IHC) in all patients with newly diagnosed colorectal (CRC) and endometrial cancer (EC) was implemented in Iceland in 2017. The aim of the study is to assess the accuracy of screening in 2020–2022 and compare it to 2017–2019 when screening was initiated.
Patients/materials and methods: All patients diagnosed with CRC and EC according to the Icelandic Cancer Registry in 2020–2022 were included. Screening results were crossmatched with a genotyping database from deCODE to calculate sensitivity and specificity for LS detection.  
Results: In 2020–2022, 429 of 522 (82%) diagnosed CRCs were stained and 90 of 106 (85%) ECs, compared to 74% of CRCs and 82% of ECs in 2017–2019. The screening protocol was followed in 90% of cases for CRCs and 95% of cases for ECs compared to 89% and 68% during 2017–2019. The sensitivity of IHC as a screening method for LS was 70% and specificity 88% with a positive and negative predictive value of 8.4% and 99.4%, respectively.
Interpretation: Three LS cases were missed with MMR IHC (1 MSH6 and 2 PMS2 carriers), it is possible these patients had sporadic cancers unrelated to their LS carrier status. MSH6 and PMS2 deficiency strongly predicts LS in Iceland.

Background: Antiviral therapy is an essential treatment for chronic hepatitis B (CHB) infection. Although hypophosphatemia is an important adverse effect of antiviral agents, its clinical significance remains unclear. We investigated the incidence and clinical consequences of hypophosphatemia in a large cohort of CHB patients. Methods: This retrospective cohort study included CHB patients who started antiviral therapy between 2005 and 2015 and continued it for at least 1 year. Patients with decompensated liver cirrhosis, diabetes mellitus, hypertension, concomitant diuretic administration, and end-stage renal disease were excluded. The primary outcome was a change in renal function. Secondary outcomes included the incidence of infection and changes in serum potassium, uric acid, and total carbon dioxide (tCO2). Results: Among the 4,335 patients, hypophosphatemia developed in 75 (1.7%). During the median 2-year follow-up period, patients with hypophosphatemia showed a lower estimated glomerular filtration rate than those in the control group. The incidence of infection and changes in serum potassium, uric acid, and tCO2 were similar between groups. Conclusion: Hypophosphatemia was associated with a renal function decline in patients with CHB receiving antiviral therapy.

Published: January 2025

Pediatric hypertension (HTN) is a significant, growing health concern worldwide and also in Korea. Diagnosis, evaluation, and treatment of HTN in Korean children and adolescents are uncertain due to limitations in using the current international guidelines, since the recommendations by the American Academy of Pediatrics (AAP) and European Society of Hypertension (ESH) guidelines differ. Furthermore, these are guidelines for Western youth, who are racially and ethnically different from Koreans. In addition, reference blood pressure values for all pediatric age groups, which are essential for the diagnosis of HTN according to these two guidelines, are absent in Korea. Therefore, HTN guidelines for Korean children and adolescents should be established. The Korean Working Group of Pediatric Hypertension established clinical guidelines for the diagnosis, evaluation, and management of HTN in Korean children and adolescents. These guidelines were based on reported clinical evidence, expert recommendations, and AAP and ESH guidelines. The characteristics of Korean youth and the Korean medical and insurance system were considered during the establishment of the guidelines. By providing recommendations suitable for Korean youth, these guidelines will help in the prevention and management of childhood HTN, thus relieving the burden of cardiovascular disease in adulthood in Korea.

Published: January 2025

Introduction: Leishmaniasis is an insect-borne disease caused by Leishmania. In East Africa, Sudan has the highest prevalence
rate (50-60%) of post-Kala-azar cutaneous leishmaniasis. The Central African Republic, which borders the two Sudanese
countries, is subject to population movements linked to military and political crises on both sides, which are conducive to the
spread of the disease. The aim of this study was to assess the knowledge and attitudes of the population of the city of Birao.
Patients and Methods: This was a prospective, descriptive, cross-sectional study carried out in Birao from August to
September 2024.
Results: Age ranged from 20 to 57 years, with an average of 36 years. The 31 to 40 age group was the most represented
(40.64%). The sex ratio was 1.5. Leishmaniasis is known to the population of Birao, with the vernacular name Am-Chabach
(98%); the people surveyed (86.45%) declared the disease transmissible by mosquito bites. Some respondents (65.80%) did
not know the degree of impact of leishmaniasis on their general condition; others (98%) said they had never had leishmaniasis.
Treatment by the population consisted in applying oil to the pimple or wound before applying a braised knife.
Conclusion: leishmaniasis is known in the population of Birao, along with its mode of transmission. Treatment remains
traditional, but means of prevention do not exist, hence the need to raise awareness and provide health facilities with antileishmanial drugs.
Cyber VAT Fraud in the EU: A Criminological Analysis
Authors: G Baratto , D Boriero , A Di Nicola , G Perrone
Published: January 2025

This article is an anticipation of the criminological analysis of cyber VAT fraud in the European Union carried out in the
framework of the project "EU CYBER VAT - Fighting cyber-VAT fraud in the EU: a comparative criminological and criminal
law study", co-founded by the Union Anti-Fraud Program (EUAF) of the European Anti-Fraud Office (OLAF). In its empirical
criminological perspective, the EU CYBER VAT project investigates behaviors in cyberspace that harm the EU's financial
interests through VAT evasion and assesses how digitalization affects the commission of these crimes. More specifically,
it investigates how the Internet creates new criminal opportunities for VAT fraud and influences the organization of these
crimes, both in terms of criminal activities and the means of communication between network members. To achieve this goal,
a script analysis was used to classify the criminal opportunities that the Internet provides to fraudsters; for each criminal
activity considered, the script framework was used to determine how the Internet has an impact. Data was collected through
case studies, focusing on court cases selected by national experts and relevant stakeholders (e.g. national and supranational
authorities and bodies involved in the fight against VAT fraud). The analysis shows, among other things, that the Internet not
only facilitates connections between sellers, intermediaries and buyers, but also speeds up transactions and promotes trade
by enabling the easy sale of transferable intangible goods. More comprehensive results will be presented in the final report of
the project and will contribute to the development of more effective counter measures.

Entrepreneurship education is a crucial process for digital entrepreneurs in the era of escalating digital transformation. Teachers represent one of the key elements who must possess adequate competencies in teaching digital entrepreneurship. The research aims to analyze the factors influencing the digital entrepreneurship competence of teachers derived from the institutional school environment and the background of business ownership and gender. This research is a quantitative study employing survey methodology, and data collection techniques involving the use of questionnaires. The survey was conducted in 11 Vocational High Schools, comprising 81 teachers. The research findings indicate that institutional environmental support in the form of cognitive, normative, and regulative aspects significantly influences the digital entrepreneurship competence possessed by entrepreneurship teachers. Other influences can be observed from teachers' internal factors (entrepreneurial background and gender), however, these influences have low significance in affecting teachers' digital entrepreneurship competence. Researchers may conduct broader explorations regarding other factors that may influence teachers' digital entrepreneurship competence.

Teachers' understanding of how to improve students' reading skills and the lack of attention to measuring students' reading results, which causes students to need more information on their reading results. This study analysed the correlation between reading comprehension ability, metacognitive components, and inferential ability using digital big books. This research method uses a factorial analysis design to see the role of metacognitive variables and inferential ability on reading comprehension. This study involved 200 elementary school students from 4 schools. The sample was taken randomly. The data collection method used was a test. In contrast, the data collection instrument for students' metacomprehension skills was measured using the ESCOLA reading awareness scale, commonly used in students aged 10-15. The reading awareness measurement scale consists of 55 multiple-choice questions to assess three dimensions of metacomprehension, namely planning, monitoring, and evaluation. The data analysis used in this study was the Bonferroni analysis. The researcher selects the data obtained from the reading awareness scale, reading comprehension test, and its acquisition before analysis. The results showed that individual reading comprehension ability can predict metacomprehension accuracy. This study implies that teachers can consider these aspects while optimizing the role of these variables to improve students' reading comprehension skills.
