Abstract

Posters remain a strategic medium in visual communication due to their ability to attract attention quickly and convey information efficiently in public spaces. Beyond graphic design elements such as layout, typography, and imagery, surface finishing plays a critical role in shaping visual perception, readability, and audience response. Among the most widely used finishing techniques, glossy and matte (doff) lamination exhibit distinct optical, psychological, and functional characteristics that directly influence communication effectiveness. This study aims to comparatively review glossy and matte lamination applied to posters through a narrative literature review approach. Peer-reviewed journal articles, conference proceedings, and authoritative books indexed in reputable databases including Scopus, Web of Science, IEEE Xplore, ScienceDirect, SpringerLink, and Google Scholar were systematically collected. A total of 42 relevant publications published between 2013 and 2023 were selected and thematically synthesized. The review reveals that glossy lamination enhances color vibrancy and contrast through specular reflection, thereby increasing immediate visual attraction, but often introduces glare that compromises readability and visual comfort. In contrast, matte lamination provides superior readability and reduced visual fatigue under diverse lighting conditions, conveying a professional and elegant impression, although with slightly reduced color saturation. The findings highlight that lamination selection is not absolute but context-dependent, influenced by message objectives, target audience characteristics, and installation environment. This review also identifies significant research gaps, particularly in neuro-cognitive audience response measurement, long-term durability under tropical environmental conditions, and cross-cultural perception of surface finishes. Based on these gaps, a structured research roadmap is proposed. The study contributes an evidence-based framework to support designers, printing practitioners, and visual communication scholars in making informed finishing decisions.

Abstract

The rapid development of information and communication technologies has significantly increased both the number and complexity of cybercrime cases. These crimes often involve sophisticated technical processes that exceed the professional competence of investigators, prosecutors, and judges who are primarily trained in legal sciences. As a result, the effectiveness of cybercrime investigations largely depends on the proper use of expert examinations based on specialized technical knowledge. This study aims to analyze the role and significance of cyber expertise in solving cybercrime cases, identify the shortcomings of existing computer-technical (digital forensic) expertise, and justify the need for a more comprehensive and specialized classification of expertise in the field of information and communication technologies. The research employs doctrinal legal analysis, comparative analysis, and a descriptive-analytical method. National legislation of the Republic of Uzbekistan, law enforcement and judicial practice, and foreign experience in the application of cyber and digital forensic expertise were examined, alongside technical aspects of telecommunication networks, information systems, software, cryptography, and communication quality. The findings demonstrate that the prevailing reliance on computer-technical expertise is insufficient to address the multifaceted nature of cybercrimes, which frequently involve telecommunication infrastructure, encryption technologies, software applications, and communication quality issues beyond the traditional scope of digital forensics. The study substantiates the need to introduce specialized types of expertise, including telecommunication network and infrastructure expertise, information systems and computer data expertise, software and application expertise, cryptographic expertise, communication coverage and quality expertise, and cyber forensic auditing. Particular emphasis is placed on cyber forensic auditing as a mechanism for ensuring the admissibility and reliability of digital evidence. The study concludes that the current forensic framework should be expanded and systematized, and recommends developing specialized expert training and updating procedural legislation to enhance the effectiveness of cybercrime investigations.

Abstract

The rapid advancement of artificial intelligence (AI)-driven personalization in e-commerce has introduced algorithm-based dark patterns that subtly manipulate consumer behavior and potentially distort decision-making processes. This study aims to analyze the effect of personalization-based dark patterns on consumer decision distortion by integrating perspectives from behavioral economics and business ethics. A quantitative approach was employed using a scenario-based survey involving 212 active e-commerce users. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) to examine both direct and indirect relationships among variables. The results indicate that personalization-based dark patterns have a positive and significant effect on consumer decision distortion. Additionally, cognitive biases, particularly loss aversion and anchoring effect, significantly mediate this relationship. Loss aversion is found to be the more dominant mediating factor, suggesting that consumers are more influenced by the fear of missing out than by reference-based judgments. These findings confirm that digital consumers are not fully rational, as their decisions are shaped by psychological biases exploited through system design. In conclusion, algorithm-based dark patterns significantly contribute to distorted consumer decisions through both direct influence and cognitive mechanisms. This study recommends the implementation of more transparent and ethical interface designs, as well as stronger regulatory frameworks to limit manipulative practices. The findings provide theoretical implications by integrating technological, behavioral, and ethical perspectives into a unified framework, and practical implications for developers and policymakers in promoting responsible and sustainable digital platforms.

Abstract

Fine motor development is an essential aspect of early childhood education because it supports children’s readiness for writing, drawing, and other daily learning activities. However, learning activities in many early childhood education institutions are still dominated by conventional approaches that provide limited opportunities for children to engage in direct and meaningful experiences. This study aimed to analyze the effectiveness of cooking class learning on early childhood fine motor development based on N-Gain scores at RA Baitul Ibadah. The study employed a quantitative approach using a quasi-experimental design involving 40 children aged 5–6 years divided into experimental and control classes. Data were collected through observation sheets, pretest-posttest assessments, and documentation, then analyzed using descriptive statistics, N-Gain analysis, normality tests, homogeneity tests, and independent sample t-tests. The results showed that the experimental class achieved a higher posttest mean score (37.55) compared to the control class (26.75). The average N-Gain score in the experimental class reached 66.35%, while the control class obtained 29.16%. Hypothesis testing indicated a significant difference between both classes with a significance value of 0.000 < 0.05. These findings indicate that cooking class learning effectively improves children’s fine motor development through hands-on learning experiences. Therefore, cooking class activities are recommended as innovative and child-centered learning strategies in early childhood education.

Abstract

Aircraft component reliability is essential for maintaining flight safety and operational continuity. The Pressure Regulator Shut-Off Valve (PRSOV) is a critical component of the CN235 bleed air system because it regulates and shuts off pressurized air supplied to the aircraft environmental control system. Historical maintenance records indicated 17 PRSOV-related failures during 0–8,952 flight hours, including failures involving the valve, connector, diaphragm, seal O-ring, spring, and solenoid. This study aims to characterize PRSOV reliability, identify dominant failure modes and their causes, and develop reliability-based preventive maintenance recommendations. A quantitative reliability analysis was conducted using a two-parameter Weibull distribution, supported by Failure Mode and Effects Analysis (FMEA) and Fault Tree Analysis (FTA). Weibull analysis indicated a shape parameter greater than one, representing an increasing failure-rate pattern and suggesting the influence of component aging and wear-out mechanisms. FMEA was used to prioritize failure modes based on severity, occurrence, and detection, while FTA was applied to identify the logical relationships among basic failure causes. The integrated results indicate that preventive maintenance intervals should be differentiated according to component-specific reliability characteristics and failure risks rather than relying solely on the manufacturer's general maintenance interval. The proposed approach provides a basis for improving PRSOV reliability, reducing unscheduled maintenance, and supporting CN235 operational safety.

Abstract

Menstrual health is an important component of reproductive health and overall well-being among adolescent girls and young women. This study assessed menstrual health awareness, menstrual characteristics, and hygiene management practices among college-going girls. A cross-sectional observational study was conducted at Malineni Perumallu Educational Society between January and April 2026. Data were collected using a structured questionnaire administered through Google Forms after informed consent was obtained. Of 473 students who participated in the survey, 372 met the study criteria and were included in the analysis. Descriptive data were presented as frequencies and percentages. Among the participants, 44.1% were aged 20–21 years. Regular menstrual cycles were reported by 77.1% of participants, while 22.9% reported irregular cycles. Most participants (75.8%) reported cycle intervals of 21–35 days, and 52.3% reported menstrual bleeding lasting 4–6 days. Sanitary pads were the most commonly used menstrual product, and most participants reported changing pads every 2–4 hours. Academic stress was the most frequently reported stress-related factor affecting menstruation. The findings indicate generally satisfactory menstrual hygiene practices, but menstrual irregularities and stress-related disturbances remain important concerns. Comprehensive menstrual health education, stress management, appropriate healthcare-seeking behavior, and improved access to affordable menstrual hygiene products are recommended to support reproductive health among college-going girls.

Abstract

The transition toward low-carbon and environmentally responsible shipping is creating new competency requirements for maritime vocational graduates. This study examined the gap between sustainability competencies required by the maritime industry and those addressed in Nautika curricula, developed a Green Compass curriculum framework, and evaluated its initial instructional effectiveness. A sequential mixed-methods design was conducted across AMANJAYA, AMD, and STMT Malahayati from April 2025 to January 2026. The study involved 180 cadets and 15 industry stakeholders in the needs analysis, a 20-expert Delphi panel for framework validation, and a six-week pilot involving 60 cadets and a 60-cadet comparison group. Baseline competency was low, particularly in ESG Leadership (M=2.18/5.00), followed by Green Port Operations (M=2.61) and Technical Green Competency (M=2.84). Sustainability content represented approximately 5.3% of mapped curriculum contact hours, while ESG Leadership was not explicitly addressed. The pilot produced significant improvements in all domains, with the strongest gain in ESG Leadership (d=2.12). Delphi validation reached 88.4% consensus. The findings support integrating technical green competencies, green port operations, and ESG literacy into existing Nautika courses through interdisciplinary curriculum integration and lecturer professional development.

Abstract

Maritime vocational education commonly evaluates cadet competence through academic examinations, seamanship assessments, and English communication proficiency, while physical fitness, mental well-being, and cognitive load management receive comparatively limited attention as integrated dimensions of career readiness. This study examined the relationships among physical fitness, mental well-being, cognitive load, and career readiness among Nautika cadets and evaluated an eight-week integrated wellness programme. A two-phase sequential design was employed. In Phase 1, data were collected from 180 Nautika cadets at three Jakarta-area maritime institutions using the 20-metre shuttle run test for estimated VO₂max, the Patient Health Questionnaire-9 (PHQ-9), the Paas Cognitive Load Questionnaire, and the Maritime Career Readiness Inventory (MCRI). In Phase 2, 90 cadets were randomly assigned to intervention (n=45) and waitlist control (n=45) groups. Baseline findings indicated that 61.1% of cadets had VO₂max values below 38 ml/kg/min, 28.3% reported at least mild depressive symptoms, and 47.2% reported high cognitive load during bridge simulation. Career readiness was significantly associated with VO₂max (r=0.61, p<0.001), PHQ-9 scores (r=-0.58, p<0.001), and cognitive load (r=-0.54, p<0.001). Following the intervention, the intervention group demonstrated significantly higher career readiness than the control group (F(1,87)=24.83, p<0.001, η²=0.222). The findings indicate that maritime career readiness should be addressed as an integrated academic, physical, psychological, and cognitive construct. Maritime vocational institutions should incorporate structured physical training, progressive simulation design, and psychological skills development into Nautika education.
