Item Effects of alginate coating loaded with lemongrass essential oil-cyclodextrin inclusion complex on the postharvest quality of calamansi(Citrus microcarpa)Astorga, Krizzia Anne B. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2018-06)Calamansi (Citrus microcarpa) is locally grown in the Philippines and is considered to be an important commodity because of its wide range of uses. Losses of this fruit in the country already reached up to 30% because of postharvest degradation. To address this problem, three coating treatments (1% alginate, 1% alginate loaded with lemongrass essential oil-B-cyclodextrin inclusion complex, and 1% alginate loaded with lemongrass essential oil-hp-B-cyclodextrin inclusion complex) were made for the purpose of examining their potential in the preservation of the postharvest quality of calamansi. Quality parameters such as color and weight loss of calamansi, as well as pH, FTIR spectra, total soluble solids, and titratable acidity of the fruit juice were evaluated in a span of 15 days at room temperature storage. Results show that the prepared edible coatings did not significantly preserve the postharvest quality of calamansi (p > 0.05) as coated samples resulted to earlier appearances of yellow and brown peel color, higher weight loss percentages, pH, and total soluble solids content. Out of the three coating treatments, fruit samples coated with 1% alginate resulted to lower weight loss percentages, pH, TSS, and TA. Fruit samples coated with 1% alginate loaded with lemongrass essential oil-hp-B-cyclodextrin inclusion complex resulted to the highest pH, TSS, and TA, while those coated with 1% alginate loaded with lemongrass essential oil-B-cyclodextrin inclusion complex resulted to the highest weight loss percentages. Data on the titratable acidity weren’t conclusive since the results obtained were not in agreement to the expected outcome. The ineffectiveness of the coatings may be a result of unfavorable storage conditions and incompatibility of the coating materials or formulations on the calamansi.Item Effect of soil amendments on damping-off disease of tomatoBalofiños, Junnel B. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1998-04)Different soil amendments obtained commercially were tested for their ability to suppress damping-off disease of tomato. Compost, animal manure, inorganic fertilizer, and green manure were applied to autoclaved soil prior to addition of a pathogenic inoculum. The biological control of the damping-off disease was evaluated by monitoring disease incidence in every plot of 50 seedlings for 25 days. Compost and animal manure significantly reduced disease incidence while green manure and inorganic fertilizer did not yield significant results as compared to the nonamended control soil. Percent emergence, dry matter content, and height were not at all affected by the different treatments.Item A descriptive study on how adolescents respond to value-bearing communicationAsong, Mariver A.; Bobe, Minnie Marie M.; Guadalquiver, Nanette L.; Jalover, Carol P.; Niembra, Lorlyn C.; Rasmo, Anna Vina Lisa L.; Salazar, Ma. Jonalyn U.; Tupas, Euridice L. (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 1995-03)This study is an attempt to re-validate the study framework of Dr. Jacobson Kliatchko, which he used in his dissertation entitled, Communication and Attitude Development: A Philosophical Perspective. The framework deals with the development of attitudes after exposure to value-bearing communication. Because this study does not deal with the cause and effect relationship, the variables are rather called as components. The components of such study framework are: environment, value-bearing communication, and attitude. In this study, the environment is Marillac Academy. The value-bearing communication is the module on good study habits. And the attitude is the study habits of the respondents. needed data. Purposive sampling was used to determine the respondents. The essays and interviews with the students and the questionnaires filled up by the parents were the instruments designed to elicit the needed data. The general objective of this study is to determine how adolescents respond to value-bearing communication. Results reveal that although most of the respondents did not follow their study schedule, all of them have allotted time for their studies as reflected by the filled up observation sheets accomplished by the parents. This suggests that there is favorable response on the part of the respondents towards value-bearing communication. The study framework of Dr. Kliatchko that was used in the study shows that there is indeed an attitude formed when a value-bearing communication is inputted to a certain environment.Item Baranugun kang tarangban: A Shounen MangaBagarinao, Andrea F. (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2009-04)Manga is a very popular form of popular literature. It is the Japanese term for comics, but outside Japan, "manga" is exclusively used to refer to Japanese comics or Japanese-style comics. Shounen manga are comics intended for male readers. They focus on action, adventures and development of male heroes. The Rescue, the latter part of the third courting adventure consisted in The Epic of Labaw Donggon, was enhanced using styles and concepts of shounen manga. The themes and characters, which are very important elements of manga, involved in the epic and the story itself were explored and improved to create the shounen manga, Baranugun kang Tarangban.Item A benchmark survey on the cyanide and protein content in the leaves and roots of cassava (Manihot esculenta Crantz) in IloiloBacolod, Hanny Joy C. (Division of Physical Sciences and Mathematics, College of Arts and Sciences, University of the Philippines Visayas, 2006-04)The cyanide and protein content of the roots and the leaves of the cassava samples were determined. Samples were taken from five locations, namely, Mambatad, Miagao; Poblacion, Lambunao; Ambarihon, Tubungan; Naclub, Miagao; and Calampitao, Miagao. This study shows the levels of cyanide and protein in the roots and leaves of the cassava samples from the five selected locations in the province of Iloilo only. It does not establish any concrete conclusion on the cyanide and protein content of the cassava in Iloilo. Based on the results, the amount of cyanide varies among parts of the plant with an average of 229 ppm in the leaves and 100 ppm in the roots. It also varies among varieties in the same location, the white root variety having 125 ppm cyanide in the roots and 202 ppm in the leaves, while the yellow root variety has an average of 58.2 ppm cyanide in the roots and 263 ppm in the leaves. Different locations also have different levels of cyanide. Cyanide content also decreases in the roots as the period of storage is prolonged. The level of cyanide in the white root variety from Lambunao decreased by 17.1% on the 2nd day and 61.5% on the 3rd day, while the yellow root variety, also from Lambunao, decreased by only 4.3% on the 2nd day and 30.1% on the third day. Total soluble protein in the leaves (0.12%) of the samples is higher than in the roots (0.11%) . Among the roots, the amount of protein varies. It was found out that there is a significant correlation (0.750 at 0.05 level) between the amount of protein in the roots and that in the leaves of the samples.Item Molluscicidal effect of quicklime, CaO on golden snail (Pomacea canaliculata)Baibado, Joewel Tarra (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1998-03)The golden snail (Pomacea canaliculata) is presently a major pest of rice in lowland and rainfed areas through out the Philippines . The problem of golden snail infestation in rice farming system includes damage to the rice plants, rice yield losses, additional expense, side effects of chemicals and destructive effect on native snails . The study was conducted to evaluate the molluscicidal effect of calcium oxide for the control of golden snails in farmlands and to determine the 96hour LC50 in order to know the lethal concentration of calcium oxide to golden snails. Calcium oxide was found to have a molluscicidal activity on golden snails The golden snails were exposed to different concentrations namely. 100 ppm. 200 ppm. 300 ppm .400 ppm. and 500 ppm Remarkable lethal effects of calcium oxide (p<0.05) has been found in 4(H) and 500 ppm concentrations which has reached 60-100 % after the 96 hour treatment. The 96-hour LC50 within the 95% confidence interval was 322.02 ppm as computed Calcium oxide is safe on rice when used as a molluscicide It performs dual function as fertilizer/soil stabilizer and molluscide. These dual effects are very significant because it means big savings on the part of the rice farmers. Considering the prevalence of this pest, farmers spend much on molluscicides and their application. With calcium oxide, the farmer has a molluscicide and soil stabilizer in one application.Item Cytotoxicity and anti-vibriotic activity of Noni as an ethnobotanicalArrojo, Marley C. (Division of Physical Sciences and Mathematics, College of Arts and Sciences, University of the Philippines Visayas, 2005-12)The crude methanolic extract of Acacia, Alibutbut, Bayabas, Biab, Botolan, Bulobitu-un, Buyo, Kamunsil, Kasla, Kayos, Langka-langka, Noni, Pasaw, Sampaguita, Tabong, Talisay, Yellow bell, were bioassayed for their cytotoxicity using brine shrimp nauplii assay. Among the plant extracts, Noni gave the highest LCso equal to 943.329 pg/mL. Noni was the least toxic among the plants tested and its crude methanolic extract was found to have activity against V. harveyi with an anti-vibriotic index of 0.256. Sequential extraction using solvents with increasing polarity gave fractions that exhibited anti-vibriotic property but the more polar ethyl acetate fraction gave the highest anti-vibriotic index of 0.513. It appears that the anti-vibrio constituent is polar. Using VLC, the ethyl acetate fraction was further separated into eighteen fractions which were in turn pooled into five fractions, Fa, Fb, Fc, Fd, and Fe based on their TLC profile. Anti-vibriotic activity of each fraction was determined. Fraction Fa has the highest anti-vibriotic index (0.192) but this is much lower than 0.513. There must be some synergy among the polar constituents that exhibited a higher anti-vibriotic index in the ethyl acetate fraction compared to fraction Fa. Based on several color reactions, ethyl acetate fraction may contain any of the following plant metabolites such as tannins, saponins, phenolic groups, conjugated double bonds, flavonoids, sterols, terpenes, except alkaloids.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 Guerilla movement in Oton during the Japanese occupation of Panay: History and significanceAntiquiera, Remigio G. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1989-03)This is a research paper on the guerrilla movement in Oton during the Japanese occupation of Panay from April 15, 1942, up to the final disbandment of the different guerrilla units on July 31, 1945. The objectives of the study are: to find out the origin, goals, and objectives of the guerrilla movement in Oton; to identify the persons involve in the founding of the guerrilla movement in the area during the Japanese occupation of Panay; and to find out the significance of the guerrilla movement in Oton in relation to Panay's struggle to be liberated from the Japanese forces. The purpose of this study is to present, in a descriptive manner, the guerrilla movement in Oton during the Japanese occupation of Panay. The sources used are published and unpublished materials of soldiers and guerrillas, regarding their activities and experiences during the occupations. Also, the researcher was able to interview persons were actively participating in the guerrilla movement at that time, and other persons who had witnessed the Japanese occupation. The study was able to bring into light the nature of the guerrilla movement in Oton during the Japanese occupation of Panay and its significance in the defeat of the Japanese. The guerrillas of Oton, together with other unite attached to the 63rd RCT, were able to fill the gap in the overall plan of resistance in the southern towns of Iloilo. It was their active resistance that help facilitate the drive of the Americans to liberate the southern part of Iloilo. This, subsequently, weakened the southern defenses of the Japanese and enabled the combined force of Filipinos and Americans to liberate the rest of Panay.Item Relationship between media exposure and attitude of Iloilo City Junior High School students towards indigenous peoplesAmon, Abigail; Garzon, Ma. Mercedes (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2017-05)This research discusses the relationship between media exposure and the attitude of selected Iloilo City public junior high school students towards the indigenous peoples. Three hundred junior high school students from Bo. Obrero National High School, Iloilo City National High School, Mandurriao National High School, Ramon Avanceña National High School, and SPED - Integrated School for Exceptional Children served as respondents to a five-part questionnaire that included demographics, exposure to media and IPs, attitude, additional questions regarding the relationship between their media exposure and their attitude towards IPs, and the information they received and wished to receive from media. The researchers found that students were most exposed to online media and that they had low exposure to mediated content on indigenous peoples on all media platforms. It was concluded that respondents had an overall positive attitude towards indigenous peoples. Moreover, both the media industry and the educational system should be more responsible in supporting the IPs through wider media coverage and introduction to more media platforms.
