Item Antifungal activities of lemongrass (Cymbopogon citratus) essential oil -B-cyclodextrin inclusion complex incorporated in commercial fish feedsBaure, Jiaren G. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2019-06)During the wet season in the Philippines, fish feeds can be contaminated with mycotoxins, affecting fish production. The addition of essential oil (EO) is one of the ways to prevent this, but it is prone to physical and chemical reactions. Thus, this study aims to encapsulate lemongrass essential oil (LGEO) in B-cyclodextrin (B-CD) to produce an inclusion complex (IC) that can be used as an additive in commercial tilapia feeds to prevent or minimize fungal contamination. The inclusion complex was made using the co-precipitation method and was characterized by Fourier Transform Infrared (FTIR) Spectroscopy. The spectrum was similar to that of citral, a major component of lemongrass essential oil that is responsible for inhibiting fungi. The antifungal activities of pure and encapsulated LGEO at varying concentrations against Aspergillus species were carried out by the Agar Well Diffusion assay. Results showed that A. flavus was more susceptible in LGEO and IC compared with A. fumigatus. The tested concentration of EO could inhibit both fungi. However, it would take 50% IC to effectively inhibit the growth of both fungi. The stability of the inclusion complex in commercial fish feeds was also evaluated. The feeds were stored in an area with the appropriate conditions that could promote the growth of molds, such as temperature (>27°C), moisture levels (14%), and relative humidity levels (>70%). The results showed that the encapsulated LGEO was effective in extending the shelf life of the feeds and was best observed at a concentration of 5 g kg-1 IC. The oil remained active for nine days, wherein about 10- 40% of the feeds with 5 g kg-1 IC were covered with molds. On the other hand, about 70-100% of the surface of the feeds with essential oil was contaminated with molds after nine days, which indicated that encapsulation of EO was needed to maintain its effectiveness as an antifungal agent.Item Critical analysis of local newspapers' designBarbon, Krisna C.; Macahilo, September Noon A. (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)The study, "Critical Analysis of Local Newspaper Design", gives the idea of how local newspapers in Iloilo are designed through evaluation of the four elements of design namely headline, text, photo, cutline and the over-all layout of the front page. The duration for the evaluation occurred for a span of four weeks. The subjects for the study were the seven newspapers found in Iloilo City. As a result of the evaluation, it has been found out that in headline layouting, all seven newspapers failed to be consistent in following the line-column formula and the 5-10 words headline guideline. In text layouting, the common problems are the measurements of the legs of columns and jump stories. For photos found in the front page, most of them do not have borders and with excessive use of photo cliches. The photos all look natural but do not suggest actions. For cutline, not all newspapers observed proper placement which should be outside the photo. For the overall layout, majority of the newspapers have balance. The researchers observed that there is a need to improve the front page layout of local newspapers in Iloilo City.Item Study and stream: University students' behavior on online academic learning and their motivations for binge-watching on NetflixBanting, Ericka Marie; Bitoca, Joyce Anne Marie; Buergo, Angelika (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2022-06)The Covid 19 pandemic brought Netflix to unprecedented heights, especially among people aged 18 to 24. The remote setup of learning enabled students to multi-task between their schoolwork and non-academic activities. In particular, this study looks into the phenomenon of binge-watching among communication students from a selected university who are direct subscribers of Netflix. Using the framework designed by Panda and Pandey (2017) on the motivations and outcomes of binge-watching among college students, this research investigates if there is a relationship between the university students' behaviors on online academic learning and the factors that motivate them to binge-watch TV shows/series on Netflix. The research design is quantitative in nature and data analysis utilizes the Pearson's R correlation. Findings show a moderately small, positive correlation between the university students' behavior towards online academic learning and their motivations to binge-watch TV shows/series on Netflix. This means that progress in the student's behavior on online academic learning signifies an increase in their motivations for binge-watching.Item Community structure of beach forest species in Mag-aba, Pandan, AntiqueBanogon, Tharrah Anne O. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2019-06)The Philippine beach forest is one of the understudied and less-popular important ecosystem that provides great number of food and economic products in the country. In fact, we lost them much earlier than the mangrove community that there is miniscule information is existing about them. There is a need for understanding the forest status and community structure due to the rising threats of natural and anthropogenic factors. The unexplored forest patch in Barangay Mag-aba, Pandan, Antique can provide additional information on beach forest diversity and abundance in the country, thus the need for this study. This study aimed to record the different species and to provide description of the community of beach forest in Mag-aba, Pandan. Specifically, the objectives of this study are (1) identify, describe and classify the beach forest species present in the area, and (2) describe the community structure in terms of species composition, diameter at breast height and stand height, stand basal area, importance value, evenness and Shannon- Weiner Index of Diversity. The transect plot method adopted from English et al (1994) was used to obtained quantitative data. A total of 80 beach forest species representing 41 families were recorded. The family Fabaceae and the species Cocos nucifera dominated the forest community. The stand basal area of 83.24 m2 ha-1 reflects a mature beach forest community, however the community is made up of mostly low DBH classes (saplings and seedling) also indicating a regenerating forest. Mag-aba is characterized to have a low species diversity (H'=1.17), however the individual species are fairly distributed (J'- 0.83). These results are addition to the existing knowledge of beach forest community that would serve as information for conservation measures.Item Continuity and change: A generational comparison of the social representations of Martial Law in the Philippines (1972-1986)Bandoy, Laarni Lee V.; Mecenas, Eunice Marinelle Pamela C. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2023-07)A nation’s understanding of past events has implications on its national identity since it provides a point of commonality and continuation especially for nationally significant events. For the Philippines, this would be the Martial Law Period (1972-1986). Social psychological inquiries into the representation of military7 dictatorship were explored through the construct of collective memories, and previous studies on the representations of history have found that they arc aligned with Mannheim’s theory of generational effects. The current study intended to explore the generational differences in the social representations of Martial Law in the Philippines using a structural approach to Moscovici’s Social Representation Theory. Employing a mixed-method approach, this study made use of the Hierarchical Evocation Model to analyze the data collected. The findings of this study show that there is both continuity and change in the social representations of the two generational cohorts who experienced and did not experience living through the Martial Law Period. The social representations of both cohorts were grounded on concepts like politics, power, and social values such as human rights and freedom. One difference was how their social representations of the Martial Law Period were structured since the younger cohort lacked a central core, indicating a gradual change of social representations of the period over time. The way the period was objectified also differed, as the older cohort mentioned a larger selection of socio-economic changes during the period, and the younger cohort mentioned concepts of democracy and the EDSA Revolution. This study supports the generational effects conceptualized by Mannheim (1952), reflects the convergence of social representations of two generations through time as observed by Montiel (2010), and may be useful in identifying the changes in the social representations of the Martial Law Period because of historical distortion.Item The classification and regulation of AM Radio programsBalagosa, Sheena Marie K. (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)The study "The Classification and Regulation of AM Radio Programs" provides us the reasons why there is a need to classify and reinforce regulation on AM radio programs based on the MTRCB guidelines, the KBP Code, and the opinion of Ilonggo radio listeners and broadcast practitioners. The study covered 12 barangays with 400 respondents and eight broadcast practitioners from four AM radio stations in Iloilo City. From the results of the study, we have found out that radio stations created program innovations that affected the listeners. There is a need to put classification in order to separate sensitive topics that are not suitable for all listeners, to protect children by knowing which programs they can listen to, to avoid hearing double meaning words, extremely violent stories and sensitive topics about sex. There is a need to reinforce regulation because of the failure to adhere to broadcast standards of some radio programs, KBP's leniency in the implementation of its rules and regulation and the effectiveness of self-regulation. Thus, we have the determined that there is a need to put classification and to reinforce regulation in AM radio programs to protect the moral values of Filipino radio listeners.Item Court-annexed mediation: Fair and speedy administration of justice in the PhilippinesBaes, Marty V. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2010-04)The Philippine Judicial System experiences a problem characterized by clogged court dockets. Courts are having a hard time in resolving the cases brought before them. Court-annexed mediation (CAM) was adopted to supplement the traditional due process (DPL) method of resolving cases. To understand how CAM speeds up the administration of justice, the CAM and DPL method was compared to determine the differences in the length of time and the amount of resources spent for case resolution. Interviews, archival research, and participant observations were conducted. The results revealed that CAM resolve cases in a short period of time involving lesser amount of resources spent compared to the DPL method. Though CAM proves to be a speedy and expedient method of case resolution, it is not yet able to solve the problem of clogged court dockets for the reason that it is still a new method of resolving cases.Item Signification of Filipino culture in the film RPG MetanoiaAsuncion, April Angeli B.; Zante, Sheena Angelique D.; Piñano, Von Janatius (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2014-04)This study identifies and describes the different significations of Filipino Culture in the 3D animated film RPG Metanoia. It is supported by Semiotics’ basic claim that media texts are made up of signs, which are composed of two elements: the signifier and the signified. The signifier is the physical representation of a sign that is being perceived by the senses, while the signified are the meanings that are being associated with the sign. The signifiers in this study are the different physical representations of the different Components of Culture according to Panopio et al. (1978), namely, Norms, Ideas and Material Culture. Data were gathered through observation and were further analyzed using content analysis. An interview with the creators of the film was also conducted. Results show that the different significations of Filipino Culture in the film are Norms like Barkada System and Kwentuhan, Ideas which include the value of Pagkamasayahin and Belief in the Supernatural, and Material Culture which is signified by Filipino Clothing.Item Willingness to pay for the barangay loudspeaker system as an early warning device among the residents of Sebaste, AntiqueAlonzo, Dumcel Kay J.; Bangero, Denevieve Y. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2017-06)The municipality of Sebaste in Antique Province is along the path of strong typhoons that can cause damage to lives and properties. The likely effects of these typhoons and other natural or man-made disasters can be mitigated by prompt information dissemination and early warning devices. Correct information and warnings that reach people at the right time can help them prepare for the impending disaster and avoid its likely effects. In Sebaste, there is no community-wide early warning system. This study focused on the value placed by the local residents of Sebaste, Antique for the establishment of an early warning device in the form of the Barangay Loud Speaker System (BLS) by estimating their willingness-to-pay (WTP) using Contingent Valuation Method. A total of 320 study participants representing their households, equally distributed in eight barangays of Sebaste, Antique were interviewed in January to March 2017 using a pilot-tested interview schedule. Seventy-five percent of the study participants were willing to pay for the BLS. The binary logit regression showed that bid price was the only factor that significantly (and negatively) affects WTP at 1% level of significance. The estimated monthly mean WTP with and without adjustment for the level of certainty were P68.00 and P60.75, respectively. The monthly Social WTP with and without adjustment for the level of certainty were Pl84,084.16 and Pl62,293.63, respectively. This study recommends that the local government of Sebaste should invest in the establishment of the BLS in each of 10 barangays of the municipality.Item Values beyond entertainment: Audience reception on satirical film “Ded na si Lolo”Albesa, Adrianne; Dusaban, Edwin, Jr.; Paguntalan, Angela (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2015-06)This study looks into whether or not film enthusiasts recognize socio-cultural verisimilitude in the film Ded na si Lolo. The respondents of this study are film enthusiasts from the University of the Philippines Visayas who are active filmmakers and participate film festivals in Western Visayas. Data collection is done in two sessions of focus group discussion with a total of 12 participants. The film Ded na si Lolo is shown to the participants after which they are asked open-ended questions on their perception. Responses are coded and interpreted through thematic analysis. An observation in this research is that the encoded message in the film is easily decoded if the viewers are familiar with the film elements (i.e. characters, setting, plot., etc.) and also with real life issues and scenarios. However, being too familiar with film elements puts the viewer at risk of misinterpreting the message content or assigning meanings that were not intended by the filmmaker. All are able to recognize the socio-cultural verisimilitude of the film Ded na si Lolo and most of the audience, still, are able to decode the encoded message of the filmmaker. The results imply that Ded na si Lolo, being satirical in nature, has not been very successfull in delivering its message to criticize the funeral customs and beliefs of the Philippine culture. The study concludes that if the satirical purpose of the film is not fully grasped by film enthusiasts who have the ability to analyze and decode messages from the film, this might be even more challenging for the general population.
