Summary: Computer vision is a challenging field of artificial intelligence that allows computers to interpret, analyze, and derive meaningful information from the visual world. There are various applications of computer vision algorithms, with object and shape recognition being common. Pen and paper tests, which are commonly used in education, can be automated using computer vision to ease the burden on teaching staff. An automated answer recognition system has been developed to process scanned test pages and accurately identify multiple-choice questions, providing a solution to the grading process.

Summary: The need for cybersecurity education has become increasingly important for all citizens, yet it has not received sufficient attention in fields outside of the cybersecurity domain. There is a need to enhance the involvement and advancement of cybersecurity education at all levels and in every discipline. Education, audit, and enforcement are critical aspects, and the responsibility lies with all system stakeholders. It is imperative to involve and commit all stakeholders, rather than relying solely on the security team, to combat cyber threats. This paper discusses the necessity of delivering cybersecurity education across all disciplines and at all levels, with a focus on K-12, college, technical professionals, and other citizens. It proposes a curriculum roadmap that integrates cybersecurity into both technical and nontechnical curricula as a foundation for future cybersecurity education planning, aiming to introduce and apply cybersecurity concepts to students and citizens and expose them to various approaches for solving cybersecurity-related problems.

Summary: The present study investigated the validity of the paper-and-pencil Implicit Association Test (IAT) in assessing implicit preferences for English. It also examined whether these implicit preferences can predict engagement, which is indicative of performance and involvement in English. The results showed a small but significant correlation between implicit and explicit preferences. Furthermore, female participants and students majoring in foreign languages exhibited more positive implicit preferences for English. These findings confirm the validity of the paper-and-pencil IAT and highlight the impact of implicit preferences on actual English test performance through engagement.

Summary: In the context of climate change and resource depletion, sustainability and sustainable development have become the focus of industries and organizations. The higher education sector plays an important role in sustainable development by educating future academic employees. However, there are significant limitations in the available life cycle assessments (LCAs) and assessment methodologies for higher education institutions (HEIs). To address this gap, a guideline based on current LCA standards is developed to increase the availability of LCA information for HEIs. The guideline is applied in a case study for LUH, one of the leading technical universities in Germany, and the results show the major contributors to environmental impacts are transport activities, infrastructure, and energy supply.

Summary: The study found that students generally believe that assessment feedback should be specific, clear, and presented in a positive tone, preferably in a standardized format with personalized elements to be effective. They consider feedback focusing on grammar errors rather than content, provided by anonymous graders, overly personalized, and lacking in timeliness as ineffective.

Summary: This study investigated the photocatalytic degradation of rhodamine B and phenol using TiO2/SiO2 composite nanoparticles under visible-light irradiation. The results showed that the composite material achieved 100% and 43.19% degradation of rhodamine B and phenol, respectively, within 210 minutes. The major reactive oxygen species involved in the photocatalytic degradation were found to be O-2(-), h(+) and e(-) for rhodamine B, and ?OH radicals for phenol. The TiO2/SiO2 composite catalyst demonstrated stable degradation efficiency after five cycles of reuse.

Summary: In this study, the researchers successfully anchored graphene oxide (GO) layers on porous ceramic substrates using three different linkers. The same procedure was replicated on commercial ZrO2 substrates. By studying the gas permeance and water permeance properties, conclusions were drawn about the deposition morphology of the GO layers, the mode of chemical bonding with the linker, and the stability of the deposited GO laminate.
