The construction industry is one of the fields where the implementation of Occupational Safety and Health (K3) is still not optimal, as evidenced by the still high number of work accidents. Efforts to increase this awareness can be done early on through education and training, one of which is through Vocational High Schools (SMK). In general, students are still not aware of the possibility of work accidents. Providing K3 training from an early age can help students develop the knowledge, attitudes, and behaviors that will be needed in the workplace later. The purpose of this program is to provide knowledge and skills to students of SMKN 1 Kemlagi, Mojokerto Regency regarding the basics of construction K3. The methods used to educate students through K3 learning include lectures and socialization, as well as evaluation through pre- and post-tests. Overall, K3 education activities are able to improve the understanding of students in the Building Design Modeling and Information Department of all topics discussed, including risk control strategies, preventing and dealing with fires in the work area, recognizing personal protective equipment.

Background: Atherosclerosis is a chronic inflammatory cardiovascular disorder strongly associated with elevated low-density lipoprotein cholesterol (LDL-C) levels and serves as a major predictor of adverse cardiovascular events. This study aimed to investigate the relationship between inflammatory markers (adiponectin and TNF-?) and key biochemical parameters in atherosclerosis patients. Methods:  A case-control study was conducted on 60 participants (aged 40–65 years) recruited from private cardiac clinics in Fallujah, Iraq, between October and December 2024. Subjects were stratified into two groups: 30 atherosclerosis patients (diagnosed by specialists) and 30 age-matched healthy controls. Blood samples were collected, centrifuged, and analyzed for CRP, TNF-?, adiponectin, PAI-1, MDA, GSH, sodium (Na), and magnesium (Mg) levels using standardized biochemical assays. Statistical analysis was performed using SPSS, with significance set at *p* ? 0.001. Results: Atherosclerosis patients exhibited significantly elevated serum levels of CRP (2.21 ± 14.46 vs. 1.07 ± 7.76 mg/dL), TNF-? (15.14 ± 120.86 vs. 4.27 ± 65.16 pg/mL), PAI-1 (6.52 ± 0.82 vs. 2.02 ± 0.42 ng/dL), MDA (590.26 ± 29.64 vs. 155.52 ± 25.19 ng/mL), and Na (140.16 ± 1.18 vs. 125.46 ± 6.17 nmol/L) compared to controls (*p* ? 0.001). Conversely, adiponectin (0.18 ± 1.81 vs. 0.67 ± 4.18 mg/dL), GSH (22.79 ± 1.37 vs. 40.81 ± 3.05 ?g/mL), and Mg (1.46 ± 0.175 vs. 1.84 ± 0.67 nmol/L) were markedly reduced in patients. ROC curve analysis demonstrated perfect diagnostic accuracy (AUC = 1.0) for CRP, TNF-?, and adiponectin in distinguishing patients from controls. Conclusion: The study highlights pronounced dysregulation of inflammatory, oxidative, and metabolic pathways in atherosclerosis, with CRP, TNF-?, and adiponectin serving as robust discriminative biomarkers. These findings underscore the potential of targeting these pathways for therapeutic intervention and early diagnosis.

Communication is an essential part of day-to-day life. However, people who have disabling hearing loss, which in general is known as deafness, or have a severe loss of hearing use sign language for their communication. Those people learn this language through their respective schools, whereas hearing people rarely get to know this communication tool, leaving a wide communication gap. To bridge this gap, an automated communication system that can convert text to sign language without depending on human interpreters. This literature review overviews sign language and discusses the different technologies used for text-to-sign conversion systems. The paper evaluates computer-based text processing methods, machine translation techniques (rule-based, corpus-based, and neural architectures), and sign synthesis approaches (avatar animation, video concatenation, neural generation). The paper compares each method's strengths and limitations and presents quantitative performance data from recent systems. The review also provides a comprehensive summary of widely used datasets and introduces a visual taxonomy of translation approaches. Furthermore, the paper discusses the current limitations, including scalability, data limitations, the need for more expressive synthesis, and future scope for improvement. The expected outcome of this review is to find and gather information on various sign language systems worldwide, identify research gaps, and propose further enhancements in text-to-sign language conversion.

In line with current technological developments, the use of electric vehicles is expected to increase due to their environmentally friendly nature—primarily because they produce no exhaust emissions. One of the critical structural components of an electric car is the lower body. The lower body of the Rekarya EV has been specifically designed to accommodate three rows of seating. This study aims to evaluate the structural strength of the Rekarya EV's lower body under static loading conditions by analyzing von Mises stress, displacement, and safety factor values. The analysis was carried out using the Finite Element Method (FEM) through Autodesk Inventor Professional 2020. A static stress analysis was performed using ASTM A36 steel material with three different thickness variations: 1.0 mm, 1.2 mm, and 1.4 mm. The resulting von Mises stress values were 72.88 MPa, 62.24 MPa, and 51.66 MPa, respectively. The corresponding displacement values were 1.366 mm, 1.295 mm, and 1.212 mm. The calculated safety factors were 3.41, 3.99, and 4.8. Additionally, the total weight of the lower body for each thickness was calculated as 88.012 kg, 100.823 kg, and 113.613 kg. The results indicate that all three thickness variations provide adequate safety factors; however, increasing material thickness significantly affects the overall weight of the structure. Therefore, a balance between strength and weight must be considered in the design process.

Diesel engines are essential for transporting heavy loads, requiring significant engine power. This study aims to evaluate the effect of adding PTT (diesel fuel conditioner) additives to Dexlite fuel, focusing on mixtures of D0, D1, and D2. Additionally, variations in fuel pre-heating and engine cooling system fluids are examined. This research employs an experimental approach with descriptive analysis. The findings indicate that the optimal torque occurs with the D2 mixture, achieving 136.57 N·m at 2267 rpm with standard coolant, 152.03 N·m at 2100 rpm with a 50%:50% fluid ratio, and 160.70 N·m at 2033 rpm with a 30%:70% fluid ratio, all without pre-heating. The optimal power values for the D2 mixture are 74.60 HP at 4600 rpm with standard fluid, 75.23 HP at 4100 rpm with a 50%:50% fluid ratio, and 78.03 HP at 4000 rpm with a 30%:70% fluid ratio, also without pre-heating. The average results show that the D1 and D2 mixtures improve torque values by 0.77% and 4.75%, respectively, and enhance power by 0.19% and 1.53% compared to pure Dexlite. In contrast, pre-heating at 50°C, 60°C, and 70°C resulted in a decrease in torque of 1.00%, 2.26%, and 3.62%, respectively, and a reduction in power of 0.56%, 2.29%, and 4.79% compared to normal temperature conditions.
