Customer relationship management (CRM) can be used to build relationships with customers and consistently acquire, retain, and create extra value for customers, even when a crisis like the COVID-19 pandemic has occurred. The study’s primary objective was to determine and understand the customer relationship management strategies of selected resorts in Cavite during the pandemic. A descriptive[1]correlational research design was utilized in the study, and a purposive sampling technique was used in selecting targeted respondents. The researchers utilized a self-constructed survey questionnaire that 20 resort owners and managers answered in Dasmariñas City, General Trias City, Naic, and Tanza, Cavite. The result revealed that most of the respondents had operated their business for a long period of time, mostly as a sole proprietorship, and had a considerably small number of employees. The study found that the social media network was the most utilized customer relationship management strategy in the acquisition of potential customers. The marketing incentives were most used in retaining the customers. Lastly, most respondents utilized multiple channels supports to create extra value for customers. Considerably, there is no significant relationship between the business profile of the respondents and the perceived effectiveness of customer relationship management strategies except between the length of business operations and customer expansion. Despite the uncertainties brought by the pandemic to the hospitality and tourism industry, customer relationship management strategies aided the business sustainability of the resort businesses. In line with the existing new normal, this study recommended that resort firms should employ innovative strategies that are sensitive to customer trends.

5S (SORT, SET, SHINE, STANDARDIZE, SUSTAIN) implementation in a public high school of Baguio City is a community extension program of the Industrial Engineering department of Saint Louis University. The goal of this program is to address the cluttered and unorganized classrooms that also resulted to some safety issues in the school. The role of the faculty of the university was to provide training to the teachers and staff of the high school, develop activities pertinent to each level of the 5S program, guide and monitor the teachers and staff throughout the implementation of the 5S program, make periodic reports and do the impact assessment. Direct assessment was used to measure the 5S ratings of the classrooms before and after the extension program. Qualitative assessment was used to measure the impact of the extension program in increasing knowledge level and applying 5S in the school setting. The paired t-test indicated a significant improvement in the 5S rating of the school from “minimal acceptable level” to “excellent” after implementation of the extension program. The qualitative assessment results indicated that the teachers found the extension program “definitely useful” in meeting their needs for information, “significantly increased their knowledge” about 5S, and that they “definitely plan to adopt/continue with the program” in the future. The experiences shared by the teachers reveal the changes that they have undergone in the way they do things as a result of learning about 5S. Their personal account of the changes they underwent is evidence of shift in behavior as a result of imbibing 5S into their system.

The aim of this study was to provide insight on productivity and profitability of citrus nursery operation in Abia State, Nigeria. Data such as socio-economic features of the nursery operators, quantities and prices of inputs and outputs of their operation were obtained through multi-stage sampling techniques from 54 citrus nursery operators. Costs and returns analysis, productivity models and multiple regression analysis were used to analyze the data from the survey. It was shown that majority of the operators were male with average age of 47.98years, year of education of 11.35years and household size of 5 persons. The variable cost of nursery operation was 92.84% of the total cost (N637,117.56) while the fixed cost was 7.16% of the total cost. The revenue from the sales of citrus seedlings was N1,140,856.69 therefore the gross and net margin of the ventures wereN503,739.13 and N454,580.08 respectively. In addition, rate of return on investment was 66.24%. The total factor cost and value of citrus output was N686,276.63 and N1,140,856.69 respectively hence the productivity index of citrus nursery production was 1.66. Results of the regression indicated that costs of labor and planting materials had negative significant while household size, years of experience and access to credit had positive significant effects on the profitability. In conclusion, Citrus nursery operation is dominated by middle – aged, educated, experience with moderate household size. It has good return on investment (ROI) with productivity above unity but high costs of labor and planting materials reduces profitability while household size, years of experience and access to credit enhanced profitability. It was recommended that youth education about gains of citrus nursery production business should be advocated considering its viability and profitability to reduce unemployment and government should prioritized extension of necessary assistance such as inputs subsidy and access to credit to the nursery operators.

Radio for advertisers is often seen as an outdated type of media. Today, the media is changing rapidly to digitalization and on-line advertising, which can be seen in radio as well. This study aims to determine the influence of radio advertisement, client radio-selection factors, and client satisfaction of radio broadcasting. Using a validated survey questionnaire and desk and filed research conducted by the researchers themselves, a descriptive research design was used to examine the 27 local advertisers of a single radio station in one city of the Province of Negros Occidental, Philippines. The advertisers were grouped according to their nature of business, organization type, length of advertising engagement, client type, and advertising package. The Mean, the Mann Whitney-U, and the Kruskal-Wallis were utilized for viewing and analyzing the study’s outcomes. Findings revealed that the influence of radio advertisement is generally high. Specifically, results showed that the influence of radio advertisement on sales is high while moderate on market shares and the extent of radio selection factors is high. The study also revealed that advertisement cost is of utmost consideration among advertisers when selecting which station to advertise and that they are happy with the services of the radio advertising. Likewise, the digital broadcasting revealed a moderate influence both on sales and on market shares. The absence of differences on the extent of advertising influence to sales and market shares, the extent of radio selection factors, and the extent of advertisers’ satisfaction is also evident. Further, the findings revealed no significant difference between the advertising package and sales and between advertising package and market shares. The study’s findings enable radio advertisers and radio stations to investigate novel programs and marketing strategies that will support business operations and boost profit margins year after year.

This study conducted identification of phytochemicals in guava and expunge the antimicrobial capacity possessed by the plant on some bacteria. Ethanol and water were utilized to make the plant extracts that are used against Escherichia coli, and Shigella dysenteriae all isolated from clinical isolates. The results showed that the phytochemicals were present in leave extracts of P. guajava. The plant contains alkaloid, saponins, flavonoids, tannins, steroid. The antibacterial activity of aqueous and ethanolic leaves extract of P. guajava revealed the mean diameter of zone of inhibition of extract on the test isolate with E. coli spp being the most susceptible isolate at 200 mg/ml concentration (20 mm). The ethanol extracts revealed the highest activity against the test bacteria, Escherichia coli (20mm zone of inhibition, MIC of 12.5mg/ml, and MBC of 25mg/ml) followed by Shigella (18.3mm zone of inhibition, MIC of 6.25mg/ml and MBC of 25mg/ml). The aqueous extracts showed slightly lower activity on the test organisms compare to the water extracts. Escherichia coli (8.6mm zone of inhibition, MIC of 12.5mg/ml and MBC of 12.5mg/ml), followed by Shigella (5mm zone of inhibition, MIC of 12.5mg/ml and MBC of 25mg/ml). The obtained result displayed that both extracts impede the growth of the test isolates using 6.25 – 25mg/ml concentration. In turn, the leave contains of the plant can be improved to benefit from its antibacterial and phytochemical compounds.

According to the Agriculture and Consumer Health Department (2017), odor is associated with the main environmental and societal problems throughout pig farms affecting 72% of nearby residents and 30% of workers in the Philippines (Drucker et al., 2007). The synergistic activity of Malunggay (Moringa oleifera) leaves with Sodium percarbonate (2Na2CO3•3H2O2) was aimed at deodorizing pig farm wastewaters to decrease the presence of odorant compounds. Investigations were: I. Screening for peroxidase, II. Laboratory analyses for Volatile Organic Compounds (VOCs), Hydrogen sulfide (H2S), and Ammonia (NH3), III. Perceptual Odor Assessment of Human Panel, IV. Shelf-life determination. Screening showed that malunggay leaves contain peroxidase, an enzyme that can convert toxic materials into less harmful substances (Albuquerque et al., 2019). For laboratory analyses in the experimental and negative control groups, the Colorimetry for H2S showed 48 mg/L and <1.0 mg/L respectively; Phenate method for NH3 showed 124 mg/L and 121 mg/L respectively; Gas Chromatography detected no other VOC except chloroform. 32 µg/L and 17 µg/L were found, respectively. Using the 9-point Hedonic scale for perceptual odor assessment of a human panel, results showed that in terms of odor intensity, there was an 82.76% decrease in the negative control (Strongest Odor Imaginable) to the experimental (Moderate Odor). While there was an 80% decrease in unpleasantness from the negative control (Extremely Unpleasant) to the experimental (Neutral Pleasantness). After shelf-life determination, the malunggay leaves powder lasted for 8 weeks. For further validation of results, additional studies on the synergistic activity of plant peroxidases and peroxides must be conducted with various methods of application and testing.

Active Learning techniques, designed to make the students active and collaborative participants in the learning process, are gaining popularity as a supplement and alternative to traditional lectures. The purpose of this paper is to assess and evaluate the use of TPS as an active learning technique in the urban land use planning class of the surveying engineering department. Quantitative research was deployed. The class has a 50-sample size. The results of students’ average result of the pretest (without TPS) and posttest using the Think Pair Share (TPS) method has increased from 8.975(44.98%) to 11.43(58.23%) out of 20(100%). The normalized gain for each student is 0.24(i.e. low and better than the pretest), but the value denotes a positive gain in the performance of the student’s result. The witnessed level of satisfaction of students with this teaching intervention showed that the students have positively perceived that the use of the lecture method is not enough to learn urban land use planning courses effectively. On the other hand, the result of Cronbach’s alpha coefficient data analysis of the witnessed level of satisfaction of students with TPS teaching intervention for the ten items is 0.797, suggesting that the items have relatively high internal consistency. So the majority of the respondents’ students perceived the use of TPS as active learning is more essential than the traditional lecture.

An empirical gap was observed concerning published scholarly works conducted focusing on the relationship and direct effect of TikTok utilization on students’ engagement. Therefore, conducting an inquiry regarding this issue is highly recommended. In this regard, this comparative, correlational, and causal study is focused on examining the relationship and direct effect of utilizing the said application to the engagement of students in the City College of Angeles, Angeles City, Philippines. Data are obtained by conducting an online survey to a sample of undergraduate students (NMale = 238(38.5%), NFemale = 380(61.5%). Based on the findings, it was discovered that no observed significant variance concerning TikTok utilization [Male (Mdn = 2.67) and Female (Mdn = 2.62), U(NMale = 238, NFemale = 380) = 116236.000, z = -.637 p = .524, r = -0.025)] and students’ engagement [Male (Mdn = 3.29) and Female (Mdn = 3.19), U(NMale = 238, NFemale = 380) = 114478.000, z = -1.451 p = .147, r = -0.058)] with respect to gender. Interestingly, a positive association was observed between the two variables [r(616) = .336, p < .05)]. Finally, it was found that TikTok utilization positively predicts students’ engagement [F(1, 616) = 82.574, p < .001], and the R 2 = .118 displayed that the model explains 11.8% of the variance in students’ engagement. Based on the findings, proposals for students, teachers, and future studies are presented as a result of this investigation.

The Philippine General Hospital (PGH) is a tertiary hospital in Ermita, Manila, that was founded on August 17, 1907. It adheres to the philosophy of providing all Filipinos with internationally competitive, cost-effective, compassionate, and accessible health care. It was recently one of the COVID-19 facilities. The PGH sits 9.2 kilometers east of the West Valley Fault, making it more vulnerable to ‘The Big One,’ a 7.2 magnitude earthquake. Until present, no research has been done to examine the PGH’s seismic susceptibility in the case of a large-magnitude earthquake. In keeping with this, the study intended to analyze the seismic susceptibility of the Spine Building, one of PGH’s oldest structures. It focused on constructing fragility curves to assess if the building could sustain a 0.4g peak ground acceleration (PGA) earthquake with a maximum likelihood of exceedance of 10%, as required by the Philippine National Structural Code (NSCP) for Seismic Zone 4 sites. The study employed 12 worldwide and 12 local earthquakes from the Incorporated Research Institutions for Seismology, with PGA excitation levels ranging from 0.1g to 3.0g (with a 0.1g gap) (IRIS). The structural model of the PGH Spine Building was created using SAP2000, which was subsequently utilized to perform Pushover Analysis using the Capacity Spectrum Method (CSM). The PGH Spine Building might collapse with 0.538g PGA, which corresponds to Intensity VIII, according to the results of the developed fragility curves, producing significant structural shaking. Furthermore, for 0.4g PGA, the calculated highest likelihood of exceedance in the ‘collapse damage’ condition was 5.24 percent, with no results above 10%, implying that the PGH Spine Building complies with the NSCP seismic requirement for structures located in Seismic Zone 4. As a result, an adequate retrofitting strategy is not required for the PGH Spine Building.
