Item Negrosanon, indi tikalon: The severed ties between Ilonggo and Negrense identity and the creation of Negrense "Tikalon" stereotypeCaberte, Kizhi G. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2023-07)The Negrense "tikalon" stereotype has acquired popularity in recent years as a result of its virality on numerous social media platforms. The amusing banter between Ilonggos and Negrenses culminated in the return of the long-established "tikalon" stereotype. This piqued the researchers' curiosity in investigating the phenomenon and studying its emergence. This study investigates the "tikalon" stereotype of Negrense identity and how it can be explained using economic scarcity theory. The researchers argues that the Ilonggo people's creation of negative stereotypes about their Negrense neighbors, such as "tikalon" and "hambog" (proud), was a result of their insecurity over their own economic shortcomings in comparison to Negros Occidental’s economic affluence during the 1930s. When the sugar industry prospered in Negros due to a new generation of entrepreneurs who established big plantations at the time, it created a significant gap between Negros Occidental and Iloilo. This study utilizes narrative by Ilonggos in addition to a literary analysis of the works of Ramon Muzones through Ma. Cecilia Locsin-Nava. This paper asserts that Ilonggos who experienced economic deprivation channeled their anxiety and frustrations by creating the stereotypes about Bacolodnon in order to maintain and uphold the preexisting status quo.Item Antidiarrheal activity of Pterocarpus indicus bark extracts using castor oil-induced diarrhea model on miceCabatea, Norberto C. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2010-04)This study evaluated the antidiarrheal activity of the bark of Pterocarpus indicus (Narra). The crude methanolic extract of the bark was subjected to sequential extraction using hexane, DCM, and ethyl acetate. These extracts were tested for antidiarrheal activity in vitro using the castor oil induced diarrhea model in mice employing charcoal tracing method. Thin Layer Chromatography (TLC) was used in determining the chemical constituents present in every extracts using spraying reagents to aid in the visualization of spots. Crude methanolic extract dosage 200 mg/kg body weight is the comparable dosage to the reference drug loperamide (2 mg/kg body weight). The hexane extract was the most active fraction and 200 mg/kg dosage was more effective than with the positive control loperamide (2 mg/kg). No antidiarrheal activity found in the fraction of DCM and ethyl acetate extracts. Phytochemical screening revealed positive tests for tannins, phenolics, terpenes, cardiac glycosides, saponins and reducing sugars in all fractions. Tests for flavonoids and alkaloids, however, were negative.Item In vitro antibacterial activity of Hibiscus rosa sinensis leaf extracts against some pathogens associated with urinary tract infectionsCabayao, Coney B. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2011-04)The in vitro antibacterial activity of Hibiscus rosa sinensis leaf ( methanolic, dichloromethane, ethyl acetate, n-hexane, and aqueous ) extracts were studied against Gram-negative (Escherichia coli and Pseudomonas aeruginosa ) and Gram-positive ( Streptococcus faecalis) bacteria. The methanolic extract was subjected to sequential liquid-liquid extraction using solvents of varying polarity and concentrations. Out of the 5 extracts, methanolic and dichloromethane extracts exhibited the highest antibacterial activity as measured using the zone of inhibition. This was followed by ethyl acetate and n-hexane extracts. At 200 mg/ml concentration, all extracts were considered active when tested with E. coli and S. faecalis, and were partially active against P. aeruginosa. The aqueous extract was inactive towards the three bacteria. The 200 mg/ml concentration showed no significant difference when compared with the positive control, amoxicillin (12.51μg/ml). This shows that Hibiscus rosa sinensis exhibits a promising antibacterial activity. Phytochemical analysis of the active fraction- the methanolic extract- showed the presence of alkaloids, tannins, glycosides, saponins, steroids, flavonoids, terpenoids, and anthraquinones. These bioactive components could be responsible for the antibacterial activity of Hibiscus rosa sinensis leaf extracts.Item Conviviality and rebranding the T'nalak Festival's celebration of cultural diversity towards unity in South CotabatoCaaya, Hinz Benedict S., III (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2022-07)The T’nalak Festival in South Cotabato has gained attention in recent years due to its entertaining activities and unique cultural experience. During the festival, the multi- ethnoreligious cultures of the province are being highlighted especially in its street dancing event despite the history of conflicts in Mindanao. With an increasing interest in the festival, this study explores the T’nalak festival in the field of Festival Research particularly on the Cultural Studies perspective. Guided by Gerard Delanty’s Theory on Cultural Encounters specifically the encounter of cultural acceptance and Orly Levy et al’s definition of Cosmopolitanism, this study argues that in South Cotabato’s T’nalak Festival cultural acceptance is actively being reinforced for promoting unity in diversity and cosmopolitanism. Furthermore, this allows the province to utilize the festival in rebranding its image away from a province pictured with conflict and violence to a province of peaceful coexistence. Through an oral interview of festival organizers, initiators, tourism employees, community workers, volunteer, and festival participants along with analyzing government reports, pictures, videos, and existing literatures. This study finds that the T’nalak festival is a conscious effort - an invented tradition for the promotion of harmonious relationship among the multi-ethnoreligious population and a strategy that counters the negative perception about South Cotabato. The festival serves as an avenue for promotion, celebration, education and information, preservation, and unity along with the assertion of the individual local and collective community identities.Item Abundance, composition and vertical distribution of calanoid copepods in Central Sulu seaBurgos, Lora A. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2018-06)Calanoid copepods are dominant component of the copepod community, which in turn highlights their influence on the overall zooplankton assemblage of the water column. Studying their abundance and distribution, is important on understanding their role in the dynamics of commercially important organism like the fish. Calanoid samples in study, were part of the zooplankton samples taken during the Joint PhilEx oceanographic cruise on board RAZ Melville in December 2007 in the Central Sulu Sea from MOCNESS station 29. Calanoid abundance, composition and distribution were investigated. Fifteen (15) calanoid families were identified all throughout the water column (0 - 400 m). The calanoid assemblage was dominated by 27 % Eucalanidae, 12 % Rhincalanidae, Scolecitrichidae with 7 % and other families contributing to roughly 19 % of the total. The water column was divided into 2 distinct depth cluster based on species distributions; (1) layers above thermocline (0 - 150m) and (2) deeper layers (200 - 400m). Furthermore, upper layers were characterized by distinctive calanoid family assemblage which includes; Calanidae, Euchaetidae, Eucalanidae, Candaciidae, Rhincalanidae, and Temoridae. While deeper layers, calanoid families includes; Metridinidae, Scolecitrichidae, Rhincalanidae, and Euchaetidae. ANOSIM results showed significant differences between these depth clusters, with global R = 0.81 and p = 0.01. These appear to be highly related to the thermocline in both stations, where typically higher upper-layer primary productivity can support dense communities of zooplankton.Item Growing up in culture of gambling: Explaining adolescent students' academic performance using the Theory of Planned BehaviorBurgos, Jaclyn Gay S. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2017-06)Integrating lcek Ajzen’s Theory of Planned Behavior, this study seeks to explain the factors that influence the academic performance of adolescent students. In assessing the academic performance: questionnaires for attitudes towards behavior, subjective norm, perceived behavioral control, and intention were administered to adolescent students (n=88) in rural areas of Iloilo. A Pearson-product moment correlation was used to examine the correlation between the factors and academic performance. There were five participants who joined the focused group discussion and their answers provided an indepth connection of the variables. Results of the quantitative analysis stated that attitude towards behavior, subjective norm, and perceived behavioral control are individually correlated with intention but only attitude towards behavior is significantly correlated with academic performance. The results from this study can be used in schools and related government agencies in shaping students to have a more positive outlook with regards to academic performance.Item The adsorption capacity of silica gel and rice hull ash on phenol and anilineBulatao, Ben Fermin P. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2011-04)Chemical waste has been a problem here in the University of the Philippines Visayas, Miagao, Iloilo. Various methods of removal have been utilized. Extraction of silica gel from rice hull and rice hull ash was used to remove organic compounds (phenol and aniline). In this study, silica gel and rice hull ash adsorption on phenol and aniline were investigated with varying contact time and initial concentration. Silica gel reaches its optimum adsorption of both phenol and aniline at 60 minutes contact time. Silica gel was the basis for rice hull ash’s contact time because rice hull ash is 90% by weight silica gel.. Silica gel-phenol system decreases it adsorption capacity as the initial concentration is increased from 25 ppm to 100 ppm. Rice hull ash- phenol system, on the other hand, shows that the adsorption capacity increases as the initial concentration is increased. Both on silica gel-aniline system and rice hull ash- aniline system have increasing adsorption as initial concentration is increased. As the contact time is increased, adsorption increases only until it reaches its optimum adsorption which is 60 minutes contact time where saturation is reached. Increasing initial concentration however has different effect on adsorption on all system explained by the adsorption isotherms. The isotherms show that phenol has the fastest rate to form a monolayer (K and Q°) with the greatest binding strength (b) on silica gel. It is also observed that phenol and aniline formed a monolayer (1/n) on the surface of the silica gel and rice hull ash.Item The uses and gratifications of reading fan fiction among Ilongga teensBuenaflor, Daphne Claire; Haro, Samantha Gabrielle; Rojas, Jerlyn Joy (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2017-05)Fan fiction has become quite the internet trend especially among female teens that the researchers sought to find out why readers read fan fiction and what underlying needs of the readers are gratified by fan fiction. Fan fiction is all about fictional stories written by fans on real celebrities that are either published or posted online. The study is based on Katz and Blumler’s Uses and Gratifications theory, which explains the uses and functions of the media for individuals, be it of groups, and society in general. It is a survey done on to 350 female students at the Iloilo National High School (INHS) using descriptive statistics as its method of analysis. Findings reveal that Wattpad is the most used platform in accessing fan fiction and the most read stories are under Romance. The results also show the primary use for the respondents as to why they read fan fiction is stimulation or to develop their creativity and spark their imagination. Moreover, the gratifications acquired by the readers, which are cognitive or acquiring knowledge, information, and comprehensions are parallel to why they read fan fiction in the first place. The lowest rated use is socialization and the lowest rated gratification is social integrative which are also parallel to each other Reading fan fiction for the respondents, allows them to be more motivated and to be more inventive. Although, fan fiction does not necessarily help in improving the social lives of the readers.Item Antifungal activities of alginate films incorporated with lemon grass (Cymbopogon citratus) essential oil on sliced breadBronzal, Lucile A. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2018-06)The accumulation of non-degradable and non-recyclable waste materials leads researches to venture on biopolymer films which have been regarded as the promising green substitutes of non-biodegradable plastic materials. However, food products can be subjected to contamination by bacteria and fungi. The addition of plant derived essential oil can control microbial contamination of foods by reducing the growth rate of target microorganisms or by inactivating microorganisms by direct or indirect contact. Incorporating antimicrobial compounds into films provides a different way to improve the safety of ready-to-eat foods. In this study, the efficiency of synthesized alginate films incorporated with lemon grass essential oil (LGEO) for antifungal activity on white bread was evaluated. Two sets of film were prepared the (1) LGEO - Ethanol incorporated films and (2) LGEO — β-cyclodextrin inclusion complex films via solution casting method. Furthermore, the FTIR analysis of the generated films was also assessed to identify the functional groups present in the film that facilitates its antifungal property. Experimental results showed that LGEO enhanced the antifungal properties in the films and significantly slowed down the propagation of fungi on white sliced bread. After two weeks of storage, all bread samples packed with various film samples showed fungal growth. It was found out that citral is the main component of essential oil which contributes to the inhibition of fungal growth. The incorporation of LGEO in the film decreased the O-H peak absorbance while the inclusion complex in the film increases the O-H peak absorbance and broad O-H peaks were also obtained.Item Magandang lalake: A relational study on the level of exposure to the Korean flower boy image and the male K - drama viewers' concept of masculinity and gender performativityBritanico, Hannah D.; Figuracion, Ejay Christine L.; Gelvosa, Alysha Mae S. (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2022-06)The research looks into the relationship between the male K-Drama viewers' level of exposure to the Korean flower boy image and their concept of masculinity and gender performativity, which are both in terms of appearance and demeanor. The flower boy image or the kkonminam represents a soft version of masculinity, which holds the balance of having good looks and proper demeanor, and is often seen portrayed by male K-Drama protagonists. This study is mainly grounded on Gerbner and Gross' Cultivation Theory, which gives emphasis to the media's impact on viewers' attitude and perception based on their amount of exposure. Judith Butler's Gender Performativity then serves as a supporting theory as it gives emphasis to an individual's understanding of gender and how they conduct themselves, as well as the media's role in producing and transmitting ideals of masculinity. This study uses a quantitative research design and uses the correlational method. In the analysis and interpretation of data, Spearman's Rank Correlation is used to answer the study's research problem. The results show that all the variables have a very weak positive relationship. Amongst the variables mentioned, only the level of exposure and gender performativity in terms of demeanor has statistical significance. Overall, the study concludes K-Dramas may have played a role in the respondents' concept of masculinity and gender performativity although there may be external variables involved, and that the media is a gateway for the presentation and recognition of various forms of masculinities.
