Environment and natural resources were crucial to the existence of abiotic and biotic organisms, which included human beings. As the environment degraded, one of the key solutions was the next generation’s perception, understanding, and attitude toward environmental laws. Thus, the paper studied the knowledge and attitude of Bachelor of Science in Agriculture students toward environmental laws in the Philippines. The study was conducted through a structured survey questionnaire and interview. The study revealed that students of the Bachelor of Science in Agriculture of the DEBESMSCAT-Cawayan Campus had poor knowledge and awareness of environmental laws. However, their attitude towards environmental law enforcement was considered essential. Additionally, students believed that the government was not effective in enforcing environmental laws in the country, their level of confidence in the government towards environmental law was low, and they perceived that most people were not aware of environmental laws. Lastly, community clean-up drives, tree planting, conservation of electricity, and everyone’s responsibility were pro-environmental behaviors of Bachelor of Science in Agriculture students. Therefore, strict implementation and molding of agriculture students in their subjects were necessary to strengthen their attitude toward environmental laws. It was also vital to enhance their leadership skills to influence the community as they had positive behavior in the implementation of environmental laws.

Reading is vital for learning. It makes a reader more empathetic, knowledgeable, and creative and stimulates imagination. It also helps in boosting communication, improving vocabulary and helps to discover the world. Given this context, the present study seeks to improve grade five students’ recreational reading habits through measures such as uninterrupted sustained silent reading, creating reading corner and providing reading incentives. Grounded on the pragmatism paradigm, the study employs convergent parallel design. The quantitative and qualitative data were collected through survey of 25 students and six students, respectively. The quantitative data was analysed using descriptive statistics. The qualitative data from interview were used to support the findings of quantitative data. The result of the current study revealed that intervention measures employed for this study are effective in enhancing grade five students’ attitude towards reading. The recreational reading habits also improved after implementing the intervention measures. In addition, it was also found that reading incentives motivates students the most followed by uninterrupted sustained silent reading. Therefore, teachers and parents need to encourage students to read by creating reading platform and providing incentives for the students to enhance their recreational reading habits.

Social Work (SW) educators are increasingly using a number of visual aids in their lessons to make the learning process more effective. To teach the dominant SW courses, educators in this discipline are likely to use relevant photographs, videos, posters, graphs and other visual contents in addition to textbooks. The goal of this study is to explore the current beliefs and challenges of educators by using multimedia for teaching visuals in SW courses at the tertiary level. Due to the COVID-19 pandemic and the fact that this study took place at a government institution, only educators were chosen based on their availability, experience, and willingness to take part in this research. The data was gathered through qualitative methodology. A semi-structured interview schedule was used to collect information, and finally, using the thematic approach, the data was analyzed. The findings show that incorporating visual aids with multimedia in the classroom provides a number of benefits. It enhances student comprehension, boosts participation, and keeps students’ attention focused on the substance of the lesson. The research findings also reveal that educators encounter certain obstacles, such as inadequate proficiency in utilizing multimedia with visual aids, insufficient availability of multimedia classrooms and equipment, a lack of proper training and low internet speed, the absence of backup power sources, and a lack of additional financial incentives for their supplementary efforts. The results of this study indicate that the integration of visual multimedia can augment the attractiveness and comprehensibility of instructional sessions. The participation of students in a multimedia-based classroom environment has the potential to function as a catalyst for their academic motivation.

In higher education, students’ interactions are crucial to their learning in general and to their character development in particular for various reasons. Students’ interactions can be at different levels such as student students’ interactions, student-teachers’ interactions and student-faculty interactions. Knowing the importance of students’ interaction, the aim of this study is to investigate the correlation between students’ interactions and their character in Moroccan higher education. Student’s interactions, in this study, refer to students’ interactions with their friends and classmates, teachers and the administrative staff while students’ character is defined in this study as their morals, ethics, values and citizenship. The main research question answers the question if there is a statistically significant relationship between students’ interactions and their character. 220 students filled in the online questionnaires to study the targeted correlations in addition to 17 students participated in the focus groups to elicit their opinions about their interactions among themselves, with their teachers and the administrative staff in relation to their character as well as the underlying correlations. This study is mixed methods research in that both questionnaires and focus groups are implemented to answer the aforementioned research question. The quantitative data revealed a positive correlation between students’ interactions and their character while the qualitative date confirmed previous quantitative results concerning such correlations. The results suggested that university presidents, deans, faculty staff, teachers and policy makers have to be cautious about the importance of students’ interactions in developing students’ character as well as the positive correlation students’ interactions have with their morals, ethics, values and citizenship.

The main objective of this research is determination of the situation of backyard swine production in northern Negros by describing the socio[1]demographic characteristics of backyard swine raisers in the said area; identifying the management practices they employed and the common issues they encountered in backyard swine production. A survey was conducted in the three cities and municipalities in the 2nd district of Negros Occidental which include Sagay, Cadiz, and Manapla from January to March 2022. Utilizing a questionnaire, a total of 339 respondents were interviewed on different aspects of socio-demographics, management practices, and issues confronted in backyard swine production. The data were analyzed and interpreted using the frequencies and percentages through the Statistical Package for Social Sciences (SPSS). In the aspect of socio-demographic profile, the majority of the backyard swine raisers in the 2nd district of Negros Occidental were females, were primarily housewives, and have not attended any seminar or training related to swine raising. In terms of their management practices, the majority provide commercial feeds, provide concrete housing, and practice vitamin-mineral supplementation. The majority preferred to raise fattening pigs and those who practiced breeding preferred natural mating in breeding the sow. Respondents also indicated that scours is the primary cause of piglet mortality and the respiratory problem is the leading disease observed in growing and adult pigs. The major constraints faced by the respondents include expensive commercial feeds, the low market value of pigs, and the lack of sure buyers at the time of harvest, which often resulted in no profit. Despite the problems encountered, most backyard swine raisers manage to find alternative solutions to these problems to sustain production.

Effective mitigation and control of environmental damage brought on by the improper disposal of textiles industrial effluent is particularly noteworthy. Biodegradation of textile wastewater is emerging as a successful, environmentally friendly, and promising strategy and microbial cells that contain plasmids have specific capabilities. The present study aimed to determine the presence or absence of plasmid-mediated indigenous isolates in the decolourisation of vat dyes. Studies were carried out with four bacterial isolates, namely: Klebsiella oxytoca, Bacillus firmus, Staphylococcus aureus as well as Bacillus macerans using 100 mg/L of vat dyes (vat red 15, vat brown 1 and vat black 27) in mineral salt medium for 5 days. Bacterial isolates were cured of their plasmid using sodium dodecylsulphate (0.06 g, 0.08 g, 0.11 g, 0.22 g, 5 g and 10 g) and 10 µL of ethidium bromide (EtBr) at 40 ᴼC and decolourisation was rebated. The results showed that the plasmid weight of the bacterial isolates were 1500 bps and their plasmids were not cured until when sodium dodecylsulphate and ethidium bromide were combined. High decolourisation occurred before plasmid curing with the highest value of 96% by Bacillus macerans for vat black 27 dye and vat red dye decolorization activity of Staphylococcus aureus was the lowest at 40%. After plasmid curing, the decolourisation activity of the isolate reduced tremendously to 7% by Klebsiella oxytoca. The result obtained revealed the decolourisation abilities of selected isolates and also showed that decolourisation of vat dye is plasmid-mediated revealing that the gene encoding for dye decolourisation is harbored in the plasmid.

The study employed a descriptive correlational research design, in which the graduates’ academic performance and other factors that significantly predicted their LET performance were examined from the Academic Year 2016-2018. Respondents were randomly selected from a list of NONESCOST LET takers requested from the Professional Regulatory Commission, with a total of 175 respondents identified in this study. The data were analyzed using percentages, means, standard deviations, t-tests, Pearson r, and linear regression analysis. The results revealed that LET takers have difficulty passing the specialization areas in the Licensure examination for teachers. BSEd graduates perform better in the three areas of the exam than non-BSEd graduates. High scholastic ratings and passing admission scores have a better performance in the Licensure examination. Likewise, there was a significant difference between the age, mothers’ educational attainment, course, GPA, and admission entrance score, and no significant difference in civil status, father’s educational attainment, and type of school to the LET performance of respondents. There is a significant indirect relationship between the profile of the respondents such as age, course, Entrance Exam, and Grade point average. Lastly, the respondent’s mother’s educational attainment, course, GPA, and entrance examination are significant predictors of LET performance. It is recommended the college will concentrate on the area of specialization in the conduct of review classes and strengthen the college-wide admission and retention policy. Non-education graduates who wish to take education units should be given priority to be admitted to the college’s post-undergraduate program and given enough seminars and review classes.

To evaluate the effectiveness of biometric security systems, an information theoretic framework is constructed. First, two performance metrics privacy, determined by the biometric measurements’ normalized equivocation rate, and security, determined by the biometric measurements’ key generation rate are specified. Then, it is decided that there is a fundamental tradeoff between these two measurements. First, we investigate the case where a potential attacker has no side knowledge. For this situation, the privacy-security region which defines the tradeoff mentioned above is derived. In perfect privacy biometric security systems, common knowledge among random variables plays a significant role. The case where the adversary possesses side knowledge is then considered. In this scenario, the privacy-security tradeoff has inner and outside bounds. Client-server and locally installable apps, which are getting older, have lost a considerable amount of market share to web applications. It is now possible because of some special benefits that web applications provide. They can function just as well as locally installed software and are accessible through web browsers without the need for installation or upkeep. Due to the lack of resources required by enterprises to administer them locally, web applications have gained popularity more swiftly. Now that new technologies, standards, and APIs have been developed, it is possible to employ more information security safeguards. The following sections of this article go into greater detail about web apps, web-based biometrics, and the integration of biometric authentication in web applications.

Increased efficiency in ruminant production through rumen manipulation have been of great interest to animal nutritionist, practitioners, and researchers. This study sought to understand the effect of Buffered Banana Blossom Pellets (BBBP) on rumen pH and population dynamics of ruminal bacteria and protozoa. Four treatments with four replications were randomly allocated to sixteen goats aged 4 to 6 months old. Data were analyzed using Analysis of Variance (ANOVA) in Randomized Complete Block Design (RCBD) in Statistical Tool for Agricultural Reaserch (STAR) version 2.0.1.. Treatment 1 (control), Treatment 2 (1% BBBP + basal diet), Treatment 3 (2% BBBP + basal diet), and Treatment 4 (3% BBBP + basal diet) were subjected to a 35 days experiment with the first 7 days establishment period. The result shows an increase in rumen pH. T4 with 3% BBBP obtained the highest increase in pH. The highest reduction in the ruminal bacterial count was observed in T1 with -95%. But an increase in the bacterial count was observed in T2 with 1% supplementation of BBBP. A decrease in the ruminal protozoal count was also observed in T1 with -3.01%. In comparison, there is an increase in protozoal count in treatments with the supplementation of BBBP. The nutrient content of Buffered Banana Blossom Pellets revealed a high content of minerals that neutralize the rumen ecology. It has protein (5.4%), fiber (24.8%), fat (1.5%), and carbohydrates (31.8%). It was therefore concluded that supplementation of BBBP, which is high in minerals, could buffer the rumen environment and a subsequent improvement in the population of ruminal protozoa and improvement of ruminal bacteria at 1% BBBP supplementation.
