The circular economy model is gaining traction in a multitude of sectors, including construction. Incorporating this model into construction operations is anticipated to promote environmental sustainability while improving the industry’s notorious reputation. This study investigates the knowledge level and comprehension of circular economy among 13 experienced professionals in the construction industry in Ghana. The research employed a qualitative methodology and used a semi-structured interview schedule to gather data. Participants’ responses were analyzed using a thematic approach. Seven themes were established after participants shared their opinions. The themes included reuse and recycling, waste minimization, resource management, environmental approach, passive design concepts, sustainable/eco-friendly material selection, and collaborating/partnering, with reuse and recycling being the dominant theme. The study’s findings indicate that construction practitioners were primarily concerned with reuse and recycling, with little awareness of circular economy applications. The limited knowledge and huge comprehension gap surrounding the theory and practice of circular economy must be addressed if construction professionals want a sustainable environment.

This study examined the impact of no-code platform on the efficiency of complex processes, specifically in the context of the university admission process. Using AppSheet as a case study, the study collected data for two years prior to the adoption of the platform and for one year following its adoption. The results showed a significant reduction in terms of submission time, processing time, and human/facility resources required to manage the admission process after the adoption of AppSheet. The reduction in the number of personnel required to manage the admission process, as well as the reduction in processing time, highlights the potential for no-code platforms to improve organizational efficiency and reduce costs. However, the study has several limitations, including a relatively short data collection period and a limited range of metrics used to evaluate the impact of AppSheet on the admission process. Additional investigation is required to fully evaluate the effectiveness of no-code platforms in managing complex processes and to determine the potential ethical or legal issues associated with their use. Overall, the results of the study suggest that no-code platforms have the potential to significantly improve the efficiency of complex processes and improve overall organizational performance.

The government, along with all of its branches, subdivisions, instrumentalities, and agencies, is required by Republic Act 9520’s Article 2 to guarantee that technical assistance, financial support, and other services are provided to cooperatives in order to help them grow into sustainable businesses and, in turn, create a strong cooperative movement free from any restrictions that could compromise the autonomy or organizational integrity of cooperatives. This study determined the extent of thirty (30) Negros Occidental cooperatives’ compliance with training and the extent of the cooperative performance in governance and management using standardized instruments. The result of the quantitative aspect was further validated using open – ended questions, the responses to which were gathered using Focus Group Discussion (FGD) and face-to-face interviews. A descriptive quantitative-qualitative research design was used. Statistical analyses required the use of frequency, percentage, and Chi-square. Results revealed that the majority of the participants in this study were Multipurpose Cooperatives, cooperatives with longer years of existence, and small cooperatives. Availability of funds, lack of time, and lack of training needs assessment were attributed by the cooperatives as factors for their non-compliance to mandatory and optional training. Majority of cooperatives performed to a great extent in governance and management. No significant relationship between the extent of compliance to mandatory training; optional training; and the extent of performance in governance and management at 0.05 level of significance. It is concluded that there is a need to improve the extent of compliance to the cooperatives to both mandatory and optional training as well as their performance to governance and management. It is recommended that the CDA consider reviewing the practices of cooperatives in the utilization of the CET Fund to ensure that this is used solely for training and seminars of officers, management staff, and members of the cooperatives.

The learning community has been profoundly affected by the COVID-19 pandemic. In the Philippines, Filipino teachers faced challenges such as adjustment to new pedagogical concepts, styles of delivery, and different environments due to the limitations imposed by the nationwide lockdown. The Department of Education (DepEd) shifted promptly to switch to online learning and develop the Basic Education Learning Continuity Plan (BE-LCP). This plan outlines how education will continue during the pandemic, with a primary focus on protecting the well-being and safety of students, instructors, and staff. Furthermore, the Department of Education mandated the return of five days of in-person classes two years later, when education had recovered to normal, following the effects of COVID-19. The aim of this study is to describe the levels of teachers’ self-efficacy, adjustment, and the relationship between these variables when the reopening to five-day face-to-face classes was implemented. The respondents of the study were teachers from Beata Elementary School at Pandacan, Manila. A correlational method was used to perform the research. The researchers utilized a survey questionnaire that included the Teachers’ Sense of Efficacy Scale (TSES), created by Megan Tschannen-Moran and Anita Woolfolk Hoy in 2001, as well as the Teachers’ Adjustment Scale developed by the researchers. Data revealed that there is a high level of self-efficacy (x̄ =8.04) and adjustment (x=8.38) among the Filipino elementary teachers. The study revealed a positive correlation between self-efficacy and teacher adjustment, indicating that the higher the level of self-efficacy, the higher the level of teacher adjustment.

This research determined how different preservatives affected Chrysanthemum cut flowers’ visual quality and vase life (Chrysanthemum morifolium L.). The study’s findings will benefit farmers, particularly chrysanthemum growers, producers, and dealers, by enabling them to enhance and prolong the Chrysanthemum cut flowers’ visual appeal and vase life. The study took place over a period of 23 days. There were four treatments: t0- tap water, t1- three (3) tablespoons of sugar with two (2) tablespoons of vinegar per liter of distilled water, t2- fifty percent coconut water per liter of distilled water, and t3- 200 mg ascorbic acid per 100ml of distilled water. The Complete Randomized Design (CRD) was utilized to arrange these treatments, and four replications were carried out. As a statistical tool for the study, the Analysis of Variance (ANOVA) and Tukey’s Significant Difference at a 5% significance level were used to compare means. The highest visual quality was obtained from Chrysanthemum cut flowers treated with three tablespoons of sugar with two tablespoons of vinegar in the first, second, and third week, respectively, compared to all other treatments. Also, it got the highest mean for vase life. It was found that the application of three tablespoons of sugar with two tablespoons of vinegar per liter of distilled water is significantly different and can maintain and extend the visual quality or freshness of Chrysanthemum cut flowers as well as the vase life of those flowers. As a result, three tablespoons of sugar with two tablespoons of vinegar is suggested as an alternative to other preservatives for cut flowers. Additional research studies of using sugar with vinegar on other kinds of cut flowers is recommended to validate the results.

As the world becomes increasingly complex, the demand for individuals with strong general reasoning abilities has never been more important. To meet this demand, educators and employers need a reliable way to measure the general reasoning ability of their students and employees. The Test of General Reasoning Ability (TOGRA) has emerged as a promising tool for measuring general reasoning ability. However, it has not been used in developing nations like Africa, including Nigeria. One possible reason for this is the lack of revalidation of the TOGRA in Nigeria. Therefore, to gain recognition in Nigeria’s research community and also be used with confidence, it is necessary to revalidate the test in the local context. This prompted the study. Eight research questions were drawn, a triangulation research design was adopted, and a sample of 400 persons was drawn using a multi-stage sampling approach from the Port Harcourt metropolis in Rivers State, Nigeria. Two instruments were used for data collection: the Test of General Reasoning Ability (TOGRA) and the Reynold Adaptable Intelligence Test Nonverbal (RAIT-NV). The data were analysed using various statistical tools and software. Results revealed that TOGRA possesses adequate difficulty and discrimination indices, high-reliability indices, and validity. The conclusion was that TOGRA is a reliable and valid measure of reasoning ability in Nigeria. It was recommended that it be used for research and practical purposes in educational and occupational settings.

This study investigates HIV-related behaviors, knowledge, attitudes, and practices (KAP) among college students in Region XI. It aims to understand the impact of stigma reduction initiatives on HIV testing rates, assess safer sex practices, examine KAP regarding HIV/AIDS, and investigate the mediating role of safer sex practices. Stigma reduction initiatives were found to foster supportive environments but did not significantly increase HIV testing rates. Instead, age, gender, and type of educational institution were more influential determinants of testing behavior. Demographic factors had limited impact on the choice of abstinence as a safer sex practice, emphasizing unaccounted variables in decision-making. While participants exhibited good knowledge and positive attitudes toward HIV/AIDS, variability within the sample highlighted the need for tailored interventions. Sociodemographic factors had minimal influence on KAP. The promotion of safer sex practices did not serve as a mediating factor in the relationship between efforts to reduce stigma and the rates of HIV testing. Neither stigma reduction initiatives nor safer sex practices directly impacted testing rates, suggesting the presence of unexplored variables. The study underscores the complexity of HIV-related behaviors among college students. Tailored interventions that consider demographic diversity and go beyond stigma reduction are essential. Comprehensive sexual education programs should address diverse determinants of safer sex practices. Inclusive education on HIV/AIDS is crucial, and further research is needed to explore nuanced factors influencing HIV testing and safer sex practices.

Duplication or imitation of individual keystroke rhymes is very difficult which can make it very efficient to be used for identity authentication. Over time, it is possible that the keystroke style of an individual to be learned by following keystroke information obtained when the person types text. The user’s identity can always be verified by studying the user’s keyboard input styles anytime the user uses the keyboard. The technique suggested in this study uses the keystrokes that users make while typing to verify their identities. To provide an accurate verification of whether a user is authentic or fraudulent, a model that integrates machine learning and dynamic keystroke models—Decision Tree, Random Forest, Support Vector Machine, and K-nearest Neighbors—is compared and utilized. The keystroke dynamics dataset was gathered from Kaggle and consists of 51 subjects’ keyboard dynamics data, which was collected over the course of eight sessions and six months. There are 20400 samples in all in the data. This study assessed the effectiveness of machine learning algorithms with a focus on the keystroke dynamic authentication system. Python is used for the development work, while Jupyter notebook is used as the IDE. The performance of the models for different variables is assessed using the following metrics: accuracy, error equal rate, parameter performance, threshold, training time, and testing time. According to the results, the accuracy of the Random Forest, Support Vector Machine, KNN, and Decision Tree algorithms are, respectively, 98, 97.55, 97.28, and 94.26%. Based on the comparing results, Random Forest outperforms the other models, suggesting that Random Forest can be used as the system model for Keystroke Dynamic authentication.

This research centers on language anxiety, a persistent issue impeding students’ ability to learn a new language. Language anxiety can cause students to feel inadequate in their language skills, experience self-doubt, and worry about what others think of them. This can negatively impact their performance and self-esteem. The goal of the study is to understand the perspectives of Grade 12 students at the Philippine Science High School-Ilocos Region Campus when it comes to their anxiety while using the Filipino language in their day-to-day activities. To achieve this, the researcher used a quantitative research approach, specifically focusing on Grade 12 students enrolled in the Specialization Years program. The researcher created a survey questionnaire adapted from Jugo (2020) to better suit the student respondents. The data analysis included descriptive statistics using a 5-point Likert Scale. The results showed that students experience varying anxiety levels when using different aspects of language, such as speaking (x̄ =3.19, moderate anxiety), writing (x̄ =3.41, moderate anxiety), receiving corrections (x̄ =3.28, moderate anxiety), selfperceptions (x̄ =3.45, moderate anxiety), and comprehension (x̄ =3.46, moderate anxiety). These findings emphasize the importance of recognizing and addressing language anxiety to create supportive learning environments. In conclusion, this research highlights the complex nature of Filipino language anxiety among Grade 12 students and stresses the need for customized interventions and support systems to enhance their language learning experience. The study provides valuable insights into the ongoing discourse on language anxiety and how it impacts language acquisition in educational settings.
