Published: January 2025

High energy consumption in classrooms is a significant concern, often resulting from inefficient lighting and air conditioning systems. Specifically, the problem lies in the lack of automated control mechanisms that adjust energy use based on real-time occupancy data. This study aims to develop and evaluate a system that employs a camera integrated with the YOLOv8 algorithm to detect human presence and optimize energy usage by controlling lights and air conditioning. The system's performance was assessed in three different classroom environments: two large and one small. The system's accuracy for occupancy detection varied from 13.64% to 100%, depending on lighting conditions and room size. Light control accuracy was highest in the classrooms with consistent lighting, reaching 99.77%. Air conditioning control achieved perfect accuracy of 100% in the classroom with a SHARP brand AC, with a maximum remote-control range of 7 meters. These findings indicate that the system's performance is influenced by lighting conditions and room size, with smaller rooms showing better results. The system demonstrates promising potential for reducing energy consumption in classroom settings, thereby contributing to more sustainable energy practices.

In today’s digital era, ensuring website security is crucial, especially in the education sector which is frequently targeted by cyber attacks. This  research aims to test security of the Universitas Internasional Batam (UIB) website using OWASP ZAP and Nessus. The method will be used in this research was vulnerability assessment. It will involve gathering information with the tools such as, Nmap, whois and nslookup. OWASP ZAP detected 11 vulnerabilities, categorized into 6 medium level and 5 low level, including Content Security Policies (CSP) and anti-clickjacking headers. Otherwise, Nessus only detected one medium level vulnerability, the absence of HTTP Strict Transport Security (HSTS). The difference in detection results from the tools that OWASP ZAP is better at finding web application weakness that are consistent with the OWASP Top Ten 2021, while Nessus specifically targets server and network configuration. For educational institutions, these results emphasize the importance of conducting regular vulnerability assessment to protect sensitive data. Recommended action include implementing CSP to prevent Cross-site scripting (XSS) and other injection attacks, enforcing HSTS to secure communication, and its recommend to updating software to mitigate the unknown vulnerabilities. By adopting these measures, institutions can reduce their exposure to cyber attacks, its also can maintain user trust, and strengthen overall security. This research provides a pratical framework for stregthening the security of educational websites against evolving threats. These findings highlight that the importance of using multiple tools can provide a more comprehensive view of security gaps.

On the Format and Layout of Athenian Building Accounts (Again)
Authors: Carusi Cristina
Published: January 2025

Athenian building accounts inscribed on stone underwent a gradual evolution in classical Athens. The first preserved specimens, dating to the third quarter of the fifth century BCE, adopted a “list-like format,” with receipt and expenditure entries with their relevant monetary figures organized in multiple columns. In the last quarter of the same century, by contrast, they began to accommodate many more details, attaining a decidedly “narrative format” at the expense of the user-friendly layout chosen previously. This evolution, rather than being interpreted in light of the dichotomy between the symbolic and functional purpose of inscribed documents, should be attributed to a change in the ways in which the city chose to celebrate its building achievements. Whereas “list-like” accounts emphasized the financial means the city had deployed to realize its building projects, “narrative” accounts focused on describing how a building project was carried out, pointing less to the financial aspects and more to the deployment of the human and technical resources necessary to realize it. As regards the columnar format that features prominently in building accounts, at first glance it seems to recall the uses of writing on non-stone media. However, one should not assume a direct derivation of inscribed accounts from contemporary accounting documents written on perishable materials. In fact, the two-sub-column format with numerals on the left that characterizes earlier building accounts was originally and expressly designed for inscribing financial documents in which monetary figures were to occupy a prominent position. Notably, even later “narrative” accounts, in which entries proceed in a continuous-line format with numerals embedded in the text, did not abandon the columnar format, which remained a layout feature inextricably linked to this type of epigraphic document.
Genealogical Writing and Epigraphic Layout: Some Preliminary Remarks
Authors: Marchiandi Daniela
Published: January 2025

After some preliminary reflections on the ancient Greeks’ genealogical attitude, the chapter focuses on the layout of genealogical gravestones, which consist of two main types. The first type includes individual gravestones, where the name of the deceased is followed by a linear, ascending genealogy that relates the male ancestors, expressed in a list-like style without lateral branches. The second type consists of the so-called family-tree gravestones, a typical product of classical Attica consistently associated with funerary periboloi, where names of various family members were inscribed in descending order, starting from a forefather and moving down through the generations, according to a predominantly age criterion. In both cases the layout contributes significantly to the visual communication of the genealogical message. In the first case, the mise en page was carefully planned to emphasize the line of ancestry, as in the pedigrees of Homeric heroes: long sequences of names arranged in columns stress the antiquity of the lineage and the direct filial relationships linking the deceased to a (presumably) illustrious forefather. In the second case, the attention shifts from ancestry to dynasty: the focus is on the development of the forefather’s family over time through its various ramifications. The difficulty of progressively adding the names of the most recently deceased and graphically representing the lateral branches, without abandoning the list-format, posed difficult challenges for the stonecutters. They responded with a sort of predictive layout, reserving empty spaces for individuals still living.

Inappropriate sales and processing practices in the market-to-fork beef chain were studied in major cities representative of the main regions of Côte d'Ivoire. The study was initiated to identify the risk factors associated with the processing and consumption of beef sold on Côte d'Ivoire markets. Surveys were carried out among 900 consumers, 195 butchers (fresh beef) and 195 sellers of braised beef, commonly known as Choukouya. The results showed that a total of 94.1% of respondents, including 45.1% of men and 54.9% of women, consumed beef, compared with 5.9% who did not. The average age of consumers was 31 ± 15 years (min > 15 years; max = 60 years). Potential risk factors for infection were the use of inadequate packaging, which was 89.6% for fresh beef and 49.3% (Choukouya), and weekly consumption frequency, which was 51.3% for fresh beef and 22.5% (Choukouya). The average ambient temperature was 32 ± 0.5°C. The average time taken by consumers from meat purchase to the household was two hours. 25.7% of Choukouya consumers and 12.9% of household-cooked beef consumers reported gastroenteritis symptoms (diarrhea, vomiting, fever) following consumption of these two culinary forms. The unhealthy environment was identified as a source of contamination at all the sites studied. Poor hygiene practices during the sale and processing of meat led to the possibility of infections such as gastroenteritis.

The Impact of Tibial Slope on Anterior Cruciate Ligament Reconstruction Outcomes – University Hospital Study
Authors: César Torre, , Pedro Rasteiro, , Joana Barreto, , João Gamelas, , Mykola Stasyuk, , João Torrinha, , Nuno Oliveira,
Published: January 2025

Anterior cruciate ligament (ACL) injuries are common knee injuries that often require surgical reconstruction to restore knee function and stability. Despite advances in surgical techniques, the failure rate for ACL reconstruction remains approximately 15%, emphasizing the need to understand factors contributing to suboptimal outcomes. One factor that has garnered attention is the tibial slope, particularly the posterior tibial slope (PTS), which may influence ACL injury and graft failure. Biomechanical studies suggest that an increased PTS can elevate anterior tibial translation, potentially increasing stress on the ACL and raising the risk of both primary ACL injury and graft failure. However, the clinical significance of tibial slope in ACL reconstruction outcomes remains debated. This retrospective study investigates whether an increased PTS is associated with a higher likelihood of revision surgery or poor surgical outcomes. A total of 152 patients who underwent primary ACL reconstruction or revision surgery between 2018 and 2022 with at least two years of follow-up were included. Tibial slope measurements were obtained from lateral tibial radiographs, and patients were categorized into three groups based on post-surgical outcomes: Group A (successful return to prior sport levels), Group B (stable knee without return to sport), and Group C (requiring revision surgery). The Mann-Whitney U test was used to compare tibial slope measurements across groups. No significant differences were found in tibial slope between the groups (p > 0.05). Group A had a median tibial slope of 6.08°, Group B had 6.68°, and Group C had 5.85°. These findings suggest that tibial slope may not be a major factor influencing ACL reconstruction success or failure. Other factors, including surgical technique, rehabilitation, and patient-specific characteristics, may play more significant roles. Further research is needed to explore the relationship between tibial slope and ACL ...

Published: January 2025

Odontogenic keratocysts (OKCs) are benign cystic lesions of the jaws. They are aggressive with a relatively high recurrence rate. Most often they are discovered by chance during routine radiographic examination, they typically grow in an anteroposterior direction within the jawbone without causing significant expansion. OKCs generally occur in the second third, and fourth decades of life and are rare in pediatric patients. The management of these cysts is diverse and depends on several factors. The aim of the present study was to report an odontogenic keratocyst in a 13-year-old patient, associated with an impacted mandibular canine on the right side. The case was characterized by significant vestibulolingual expansion, a feature that differentiates it from typical presentations and underscores the importance of recognizing such variations in clinical practice. Management involved an initial decompression procedure, followed by subsequent enucleation of the lesion.

Published: January 2025

Insect attacks on plants are a severe problem in the agricultural sector. The damages caused by insects have an adverse impact on plant growth which leads to slow economic growth, particularly in countries dependent on agriculture. Plant growth-promoting rhizobacteria (PGPR) are widely utilized in agriculture because they offer a viable alternative to pesticides and artificial fertilizers. The growth and life cycle of insects/pests is inhibited by the insect growth regulators (IGRs), which belong to third-generation insecticides. Lufenuron is an IGR having a broad-spectrum insecticidal activity. Lufenuron inhibits insect growth by reducing chitin synthesis. A field experiment was carried out at Ayyub Agricultural Research Institute, Faisalabad, to evaluate the effect of MUR-4 (a potential PGRP) and lufenuron on cauliflower under insect attack. Cauliflower (Naran F1) seedlings were grown with and without a potential PGPR (MUR-4) using a randomized complete block design (RCBD). Attacks of cutworms, diamondback moths, armyworms and aphids were recorded periodically. Lufenuron was applied as a foliar spray, to inoculated as well as non-inoculated plants, upon insect attack. A foliar spray of lufenuron exerted a positive effect and reduced the insect attack. Plant biochemical analysis manifested the higher activities of phenolics and proline (secondary metabolites) in MUR-4 PGPR inoculated plants. Increased levels of malondialdehyde (MDA) and H2O2 indicated oxidative stress in plants. Peroxidase (POD), catalase (CAT) and superoxide dismutase (SOD) enzymes play a very important role in defence against insect-induced biotic stress. MUR-4 PGPR inoculation enhanced the activity of the mentioned enzymes i.e. POD, CAT and SOD. We concluded that lufenuron spray can positively assist farmers in insect control strategies. Furthermore, MUR-4 PGPR inoculation improved the plant defence system against insect herbivory.

Published: January 2025

Tax revenue is the major source of public resources and tax compliance is vital for any government to have adequate financial resources for implementing development projects and provision of social services to its citizens. Effective strategies for enhancing tax compliance are those informed by research. One of the taxes that companies pay is Fringe Benefit Tax (FBT). This study investigated determinants of FBT compliance among private sector companies in Malawi, grounded in the Expected Utility Theory. The study employed a multistage cluster sampling technique through which 128 registered private sector companies out of 1133 were surveyed. The surveyed companies were those that are located in Malawi’s three major cities of Blantyre, Lilongwe and Mzuzu, where corporate concentration is highest. Data analysis was conducted in STATA by applying a Probit model to identify factors influencing FBT compliance. The findings indicate that firm size, method of tax remittance and trust of good usage significantly affect compliance. The study recommended that MRA should enhance promotion of electronic platforms for paying taxes and consider developing a special FBT package that could be more convenient to small companies. The government should work hard towards gaining more trust from taxpayers through improvements on accountability and transparency in the way public finances are spent. With the existence of Access to Information Act, it should be easy for the public to access information on government spending there by increasing trust and tax compliance.

Hydrogen production through water electrolysis is an effective method to utilize surplus renewable energy efficiently, offering advantages in energy conversion and storage, where catalysis or electrocatalysis plays a pivotal role. The development of active, cost effective, and stable catalysts or electrocatalysts is a critical prerequisite for efficient electrocatalytic hydrogen production from water splitting for practical applications, which is primary focus of this review. On the one hand, precious metals are commonly utilized to investigate the two half-cell reactions namely the HER and OER. However, the use of precious metals such as Au, Ag, Pt, Ru, as electrocatalysts, is limited by their cost and less availability, hindering their practical application. In contrast, non-precious metal-based electrocatalysts are abundant, environmentally friendly, and low-cost, which demonstrating high electrical conductivity and electrocatalytic performance comparable to noble metals. Thus, these electrocatalysts have the potential to replace precious metals in the water electrolysis process. In this review, we present key fundamental insights into water electrolysis, which not only enables higher hydrogen production but is also cost-effective.

Hughes-Stovin Syndrome (HSS) is a rare and severe disorder characterized by the combination of pulmonary artery aneurysms and deep vein thrombosis. We report the case of a 42-year-old male presenting with recurrent hemoptysis revealing HSS. Management consisted of high-dose corticosteroids and cyclophosphamide. The patient showed marked clinical and radiological improvement. HSS, as a rare form of Behçet’s disease, is associated with high morbidity and mortality due to thrombosis and potential rupture of aneurysms. Immunosuppression remains the cornerstone of management. Anticoagulation is controversial and requires careful consideration. Early diagnosis and prompt treatment are critical in managing HSS.

This study examined the structural relationships among positive perceptions of ChatGPT, creative self-beliefs, and student agency to identify psychological factors that can alleviate dependence on AI tools. Data from 889 students enrolled in 11 four-year universities nationwide were analyzed. The results of the study are as follows: First, creative self-beliefs did not have a direct, significant effect on ChatGPT dependence but exerted an indirect effect mediated by student agency. Second, positive perceptions of ChatGPT had a direct and significant impact on ChatGPT dependence. Third, creative self-beliefs and student agency demonstrated a dual mediation effect in the relationship between positive perceptions of ChatGPT and ChatGPT dependence. These findings suggest that, to ensure that positive perceptions of ChatGPT lead to beneficial usage outcomes, attention must be paid to the role of psychological factors that can alleviate dependence, such as creative self-beliefs and student agency. To promote the positive utilization of AI in the future and minimize its side effects, integrated educational strategies are required that strengthen learners' psychological competencies—such as creative self-beliefs and student agency—in addition to technical skills.

The Korean Intellectual Property Office and the Korea Invention Promotion Association developed a ‘regular curriculum-linked invention education program’ from 2022 to 2024 to integrate invention education,into regular classes, moving traditional focus on of invention education centered on after-school programs. This study examined theperceptions of 256 students from four school subjects before and after the program’s implementation, investigating whether any changes occurred. A questionnairebased on the Semantic differential method (Osgood, Suci, Tannenbaum, 1957) was employed. the result shows that the students' perception sensitivity increased in ethics and physical education after the program, whereas mathematics and music displayed more adjective groups with low perception sensitivity both before and after. Notably, the number of adjective groups that showed statistically significant changes particularly in ethics, increased significantly post-program. espite the limitations of the pilot implementation, students overall demonstrated a positive changes in their perceptions of the subjects after participating in the program, offering meaningful implications for future policy implementation.

This study aimed to examine the relationships between academic achievement goal orientation, science self-concept, and academic engagement of students who entered a science high school through the social integration admission process. Specifically, this study investigated whether there were differences in students' science self-concept and academic engagement before and after their entry into the science high school. Furthermore, the study explored how their achievement goal orientation influenced their science self-concept and academic engagement. For this purpose, 60 students(45 male and 15 female) who entered the science high school through the social integration process participated in the study, and academic achievement goal orientation, science self-concept, and academic engagement were measured using self-report questionnaires. The results showed that there was no significant difference in science self-concept before and after entering the science high school, however, academic engagement significantly decreased. Among the types of academic achievement goal orientation (performance-avoidance, performance-approach, mastery-approach), only performance-avoidance goal orientation had a significantly negative impact on science self-concept, while it did not affect academic engagement. Based on these findings, the study suggests specific educational strategies to prevent school maladjustment and support school adjustment for students entering science high schools through the social integration admission process.

O Transtorno do Espectro Autista (TEA) é um transtorno neurodesenvolvimental complexo, caracterizado por déficits na interação social, dificuldades na comunicação e comportamentos repetitivos e restritos. Estudos recentes sugerem que, além dos fatores genéticos, mecanismos epigenéticos — como metilação do DNA, modificações de histonas e RNA não codificante — desempenham papéis essenciais na regulação da expressão gênica relacionada ao desenvolvimento cerebral. Esses mecanismos são frequentemente modulados por fatores ambientais, incluindo exposição a substâncias químicas, nutrição materna, estresse e infecções durante a gestação. A integração entre predisposição genética, alterações epigenéticas e influências ambientais pode explicar a heterogeneidade clínica observada no TEA. Pesquisas apontam que abordagens baseadas em assinaturas epigenéticas têm potencial para refinar diagnósticos, identificar novos alvos terapêuticos e personalizar intervenções clínicas. Portanto, a compreensão aprofundada dessas interações é crucial para o desenvolvimento de estratégias mais eficazes no diagnóstico precoce e no manejo terapêutico do TEA.
