The level of readiness and competence of the TVL-Home Economics Graduates are measured practical execution of skills and knowledge in their workplaces which reflects the effectivity of the K-12 program to equipping the mind and skills of the learners. The K-12 starts in the Philippines in the Academic Year 2016-2017, in this connection, graduates from the strand of TVL-Home Economics are expected to respond with the conceptual and practical learnings they have grasped in their Senior High School Days. Hence, this study seeks to realize the extent level of employment readiness of TVL-HE graduates as perceived by the graduates along communication skills, conceptual sills, numeracy skills, and maturity to handle a job. Another, it seeks to know the significant difference between the level of employment readiness of TVL – HE graduates and the level of competence of TVL employed graduates in the foodservice industry. The researcher used the average weighted mean to find out the extent of readiness of the employed respondents. Survey questionnaire is used for employed TVL-graduates which is focused on the competence of the respondents in the food service industry using communication skills, conceptual skills, numeracy skills, and maturity to handle a job. Analysis of Variance (ANOVA) and Pearson were used to determine the significant difference of the level of employment readiness and competence of the TVL-HE graduates. The study revealed that the TVL-HE graduates have expressed very high readiness and high competence in the workplace which implies that they are equipped to an industry which is related to the strand they took. The significant difference between the level of TVL-HE graduates’ readiness is not significant and competence is significant. Thus, the respondents’ competence is a factor to their TVL-HE program and to the foodservice industry.

The increased rate of vehicle theft led to increasing concern among vehicle owners. In addition, most of the smaller car rental companies or personal car rental are also a concern when their rented vehicles are not returned on the date line. Thus, the purpose of this project is to study and analyse the existing vehicle tracking system. Next, a tracking system is configured and developed using the Internet of Things platform (Arduino) and web-based application. Then, the usability and functionality of the Global Positioning System and Global System for Mobile Communications module are tested together with Arduino to get the location for vehicle tracking. This project is developed using the Extreme Programming methodology. During the planning phase, requirements are gathered through a questionnaire from 40 participants. Requirements and data collected are analysed, and features that need to be included are identified. Iteration starts at design phase where every time there are changes to the system, the design needs to be changed first. Coding is done based on the features, functions, flows, and interfaces from the design phase. The code is tested before small release of part of the system. Feedback is gathered from the user after every small release of the system during the iteration. The completed system enables vehicle owners to track their vehicle through web application or Short Message Service (SMS) anytime, anywhere.

One of the major challenges of integrated water resources management is the lack of rainfall data in some regions. Satellite precipitation products could be an effective solution for the lack of data. In response to this challenge, this study evaluates the use of Integrated Multi-Satellite Retrievals for Global Precipitation Measurement (IMERG-GPM) Final satellite products, applying the Soil Conservation Service (SCS) hydrological modeling method to estimate the depth of runoff and cumulative infiltration in a basin without any rain gauge station (El Hallouf). We first compared the GPM-Final rainfall with rainfall data observed in five rainfall stations (Sidi Rahal, Marrakech, Abadla, Chichaoua and Talmest). The result reveals that the GPM-F products showed an average bias overestimation of 21.49 % and an improvement in the correlation coefficient of 0.59; 0.85; 0.78 at the daily, monthly and yearly time scale, respectively, was examined. The estimation of the depth of runoff and cumulative infiltration is done with a Curve Number (CN) sec. Using GPM-F products, the result over an 18-year period was 166.81 mm and 4.98 mm for the average depth of runoff and cumulative infiltration, respectively. This article clearly demonstrates that the integration of GPM Final products with the SCS-CN method provides a powerful tool for estimating the depth of runoff and infiltrated water in El Hallouf basin. Hydrologists and water management administrations in developing countries can benefit from the proposed method to estimate water inflows in regions where there is a lack of rainfall data.

The high population in urban areas makes the area of green open space decrease as the time goes by. Jakarta Megapolitan Area (Jabodetabek) is one of the megapolitans that are affected. The reduction of green open spaces in this area slowly impacts temperatures increase in urban areas or commonly called urban heat islands (UHI). IPB University and the University of Indonesia are two campuses located in the Jabodetabek and have contributed to urban green open space. The study was conducted to see the greenness index (NDVI) effect and size of green open space in reducing air temperature in both campuses. QGIS software was used to obtain the total area of each GOS sample. This software was also used to obtain the NDVI and LST value. NDVI values were used to analyze the relationship between vegetation coverage with LST. From the result, the comparison of NDVI and LST values in the both campuses did not show a strong correlation. In IPB University, the comparison between GOS size and LST value showed a weak negative correlation with R2 0.35. In contrast, in the University of Indonesia, GOS Size and LST value showed a strong negative correlation.

Through this research we seek to determine the implications in the relationship between the roles of human capital and the adoption of artificial intelligence in industrial revolution 4.0. A qualitative research approach was used. The research approach was qualitative, for it a literature review was carried out through the review and analysis of 79 articles related to the variables of the proposed model. The findings suggest that companies, postsecondary education institutions and governments should be prepared to re-educate and train the human capital so that they can assume the roles that artificial intelligence implies in their areas of work. Manual work will disappear over time, but careers related to administration, science, computer science, communications, health and education will become those in greatest demand. Therefore, human capital will not be able to possess the accuracy, lightness, and perfection of machines, but it will be able to take advantage of the opportunities that artificial intelligence could offer. As in many industrial revolutions of the past, many jobs will disappear, but others will emerge in which human capital will overcome automation due to its knowledge, good judgment, critical thinking and decision-making power.

This study examined vitamin C levels in smoothies made with raw versus cooked broccoli. Humans are unable to synthesize or store vitamin C and must obtain it through their daily diet. Vitamin C is a powerful antioxidant and an essential vitamin in the human diet. Broccoli is a vegetable with one of the higher levels of vitamin C versus even oranges, strawberries and spinach. Three common cooking methods used in the United States, steaming, grilling and baking were evaluated. Vitamin C levels were measured using 2,6-dichlorophenol-indophenol (DCPIP). This experiment found significantly lower levels of vitamin C in the smoothie prepared with the uncooked broccoli. The smoothie prepared with the steamed broccoli had the highest levels of vitamin C. Currently, most people prepare smoothies with raw vegetables. Using some cooked vegetables may increase specific nutrient content in smoothies and warrants further study.

The recommendation letter (RL) is a vital part of a student's academic life especially for higher studies. These letters also represent the additional skills, attitudes, and other characters of an individual. Students have to collect this letter from their institution's teacher but whom he/she knows very well. On the other hand, students are struggling to get a recommendation letter if a teacher does not know very much about a student. Nowadays universities sometimes receive fake recommendation letters. As these recommendation letters need to be checked manually for this reason, finding the true validity of a recommendation letter is extremely time consuming and the procedure to find it out is very much monotonous. Therefore in this paper, a digital recommendation letter verification system has been proposed based on blockchain technology to prevent forgery recommendation letters. This research paper shows a process on how to develop digital recommendation letters which is easy to validate through the blockchain technology. In our proposed work, a digital recommendation letter is provided through the blockchain based system instead of hardcopy or portable document format(PDF). A number of functions, algorithm, and server including HTTP API, index, data, timestamp, has, Sha256, in-memory Javascript array, HTTP server, and websocket are used to implement the proposed model.

The study was conducted from April to August, 2021 to investigate the water quality in Langahan Spring, Langahan, Sampagar, Damulog, Bukidnon, Philippines. Specifically, it aimed to: (1) determine the physical geography of the spring; (2) examine the water’s physico-chemical and microbial parameters; and (3) create precautionary measures in treating, conserving, and preserving the quality of water in Langahan Spring. Three (3) strategic water sampling stations were chosen subject for laboratory testing at Central Mindanao University. Results revealed that pH in stations 1 and 2, HPC in stations 2 and 3 and total coliform, and E. coli of all stations exceeded the maximum allowable level set by the Department of Health (DOH) in the Philippine National Standards for Drinking Water of 2017. Phosphate concentration and TSS in all water samples were also high. Enterobacter sp., Pseudomonas sp., and Shigella sp. were bacteriologically isolated. Thus, the spring’s water is not safe to drink as it can be the source of various illnesses. Information dissemination through attending sessions, limited face to face meetings and posting videos and photographs to other social media platforms were done to spread awareness and advocacy to the general public about the research study. A water reservoir with ceramic water filter, intake box, and riprap were then proposed for water treatment as intervention of this study and construction is on-going with the collaboration of LGU – Damulog and Provincial Science and Technology Center – Bukidnon, Department of Science and Technology – 10 on the progress of the study. The researchers recommended to further assess other parameters not included in this study. Recipients are encouraged to maintain, conserve and preserve the good water quality. Regular monitoring of the parameters should also be done as per advised by the DOH.

This paper is an exposition of the effects of industrial and environmental noise on humans, and how this subsequently impacts human capital development which will in turn affect sustainable national development. It equally considers the existing noise regulations in Nigeria with a view to identify the negative effects of industrial and environmental noise, is also considered. When people are unhealthy, they can hardly contribute their own quota to national development. Hence, there cannot be sustainable development without a healthy workforce or citizenry. Having identified the negative health effects associated with industrial and environmental noise and acknowledging the contribution of human capital to economic growth and development, it becomes very imperative that noise is effectively regulated. Since industrial and environmental noise affects people’s health, it will also have a negative impact on the attainment of sustainable national development. Noise pollution must therefore be controlled, using instruments of law, to reduce its effects on people and Nigeria at large. Finally, health and safety professional bodies such as the Institute of Safety Professionals of Nigeria (ISPON) can educate the citizenry by creating awareness on the harmful effects of industrial and environmental noise pollution.

The study was conducted from April to August, 2021 to produce an ecobag from Mauritius Hemp (Furcraea foetida L.) fibers. Specifically, it aimed to: (1) examine the effectiveness of the plant’s fibers in the production of ecobag; (2) compare the product’s durability to the existing ecobags in the market; and (3) create precautionary measures in improving the product. One (1) fiber rope and two (2) fiber sheet samples were chosen from the ecobag produced out of the plant’s fibers subject for laboratory testing at Central Mindanao University. Results revealed that the fiber rope has the highest breaking strength as compared to the rest of the fiber sheet samples. The produced ecobag from the plant’s fibers is durable despite of the traditional processes it went through and with lacking materials to make it sturdier like those ecobags bought and available in the market since it can withstand a load of 3.3 kgf to 5.0 kgf when its thickness is ranging from 1.6 mm - 1.8 mm. For every 0.1 mm added to its thickness, there is an additional 8.3 N or 0.841 kgf breaking strength in every fiber sheet. Hence, Mauritius Hemp (Furcraea foetida L.) fibers has the potential to be made as high-quality, world-class ecobag as alternative to single-used plastic bags and other non-biodegradable materials available in the market. Currently, the researchers collaborated with the Provincial Science and Technology Center – Bukidnon, Department of Science and Technology – 10 on the progress of the study. They recommended that local officials may plan an area/site for the propagation and cultivation of the plant and include livelihood programs out of this product. Local farmers may be encouraged for wide propagation and cultivation too. The national government may fully support the said product by establishing a machinery/factory for manufacturing ecobags from the plant’s fibers located in the municipality.

The halftone sparse bitmap image (printed quantum dots image), which is a kind of information carrier, can be used to record and hide information. This technology has attracted a lot of attention in the field of printed information anti-counterfeiting. However, because the size of the bitmap image unit is usually below 20-30(µm), when using a mobile phone to read directly, generally only low-quality images can be obtained, which is difficult to meet the allowable bit error rate requirements for information detection, correction, and decoding. Through the Generative Adversarial Networks is used to restore the low-quality image read by the mobile phone to a high-quality image and realizes the direct generation of printed quantum dots images from its complex carrier image. The experimental with a 2× upscaling factor results show that the average bit error rate of directly generating the printed quantum dots image from the carrier image has reduced by compared to recovering all the carrier images and then extracting the printed quantum dots image when the printed quantum dots are 2×2 (pixel) and the average bit error rate of directly generating the printed quantum dots image from the carrier image has reduced by compared to recovering all the carrier images and then extracting the printed quantum dots image when the printed quantum dots are 1×1 (pixel). This algorithm effectively solves the technical bottleneck problem of poor image quality of mobile phone reading probability.

The affliction of COVID-19 pandemic resulted in total technology immersion compelling teachers to digitize instructional materials and use online tools without proper training. This study investigated the utilization of Digital Instructional Materials and Digital Tools for online learning in a university. It described the DIMs and DTs used by the teachers, examined how DIMs and DTs were integrated into classroom instruction, found out how skills in utilizing the DIMs and DTs were acquired, determined the challenges impeding utilization, and identified ways of overcoming the challenges. Employing qualitative single-case study, Atkinson’s four-step investigation directed the descriptive analysis with purposively selected participants for the semi-structured interview and Focus Group Discussion. The results reported that teachers used few DIMs and DTs for discussion or lecture, pre-discussion, class activity, assessment, as main references, and as supplementary resources. The teachers acquired their skills through webinar or seminar, self-directed exploratory inquiry, peer-to-peer professional learning, online training, academic training, and experience. Teachers encountered challenges: unstable internet connection, not uploadable sizeable videos, power outage, poor video quality, students’ device incompatibility, lack of familiarity, proper training insufficiency, resistance to change, monetary resources deficiency, and time inadequacy. In overcoming challenges, teachers established communication with students, customized sizeable video, showed flexibility, utilized sound proof room, used non-noise absorbent device, and resorted to untimely video recording, converted materials to Portable Document Format, continued self-directed exploratory inquiry, online training, and webinar, asked students to take submission screenshots, opted for shared app account, and managed time.
