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 Factors affecting fertility choice among married couples in Oton, IloiloAutentico, Sheila M.; Cagalagawan, Aiza Maris G. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2008-03)The study identified the different factors affecting fertility choice of married couples in Oton, Iloilo. There were 100 participants from the three barangays in Oton. Iloilo namely: Trapiche, Poblacion South, and Buray. The dependent variable is measured by the actual number of living children the married couples have. The independent variables were classified into four categories: economic factors, biological factors, psychological factors, and geographical factors. The multivariate analysis revealed that the significant variables found to significantly affect the decision on the number of children by married couples (at 5% level of significance) are gross monthly income of the household, years of formal education of the wife, age of wife at first marriage, ideal number of children by the couple and perception of children to be of help in old age. However, the R-squared value of 30.78 indicates that there are still some factors that were not included in the model. Nevertheless, the significant variables had the expected signs.Item Marital satisfaction, gender equity, and marital conflict among selected elderly couples in Guimbal, IloiloAsorio, Shiela Mae S.; Pradilla, Lea Angela S. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2007-03)The study was conducted to find out the relationship among marital satisfaction, gender equity, and marital conflict among old married couples, as well as their pattern of conflict resolution. Nineteen (19) elderly couples from Guimbal, Iloilo married for at least 25 years and living with their families at the time of the study participated. The instruments used were the shortened version of the Comprehensive Marital Satisfaction Scale by Blum and Mehrabian (1999), the Gender Equity on Household Labor Scale, and the Conflict Resolution Questionnaire. Results show that marital satisfaction and marital conflict have a significant negative correlation at -0.460 [a=0.01 level of significance (2-tailed test)]. However, there was no correlation between marital satisfaction and gender equity at -0.214 and gender equity and marital conflict at 0.252 [a=0.01 level of significance (2-tailed test)]. The mean score (19.29) on the shortened version of the Comprehensive Marital Satisfaction Scale by Blum and Mehrabian (1999) indicates that the respondents have a high level of marital satisfaction. There was also a significant gender difference in the distribution of household labor as perceived by the males and the females with to=-16.36 (tc=<-2.042 or >2.042). Lastly, with regards conflict resolution, majority of the respondents use the compromise style. The outcomes of the study support previous studies which state that elderly marriages experience high level of marital satisfaction and less marital conflict.Item Effects of Chromolaena odorata leaves as amendments to poultry manure and inorganic fertilizer to improve growth, yield, biomass accumulation and inorganic content of tomato (Lycopersicum esculentum)Balinas, Chona Mae D. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2012-04)Chromolaena odorata (a weed in the family Asteraceae) has been shown to enhance the buildup of organic matter in a fallow system in tropical soil. Therefore, the aim of this study was to to determine the effects of Chromolaena odorata leaves as an amendment to poultry manure and triple 14 inorganic fertilizer on the growth, yield, biomass accumulation and inorganic contents of Lycopersicum esculentum. The field experiment was conducted at Agsanayan Buenavista Guimaras where the weed has wide distribution. The leaves of C. odorata were air dried and composted using Berkeley method. The compost obtained was used as an amendment to either poultry manure and inorganic fertilizer and was tested on tomato for three months in RCBD. Obtained results proved that tested treatments with amendments of C. odorata were significantly higher in lengths of shoots and roots, flower and fruit yield, amount of biomass accumulated and inorganic contents of tomato than those with no amendments of C. odorata. Therefore, C. odorata is an efficient amendment to both organic and inorganic fertilizers. It was suggested that the weed should be utilized to serve as a green manure.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 Spatial variations of Benthic meiofauna communities from Palompon Bay, Northern LeyteBalasa, Melvy June (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)Meiofauna play a significant role in maintaining ecological balance in marine ecosystems especially in the dynamics of the seagrass meadows. The meiofauna links the upper trophic level with detritus-feeding organisms. Only few studies have been conducted in the Philippines, while no studies have been. This study was conducted in Palompon, northern Leyte in November 2011, to determine the spatial distribution of meiobenthic fauna in the area and to compare community structure in terms of species composition, species density, and species diversity among five stations included in the survey. Twenty taxa were identified with nematodes being numerically dominant, followed by harpacticoid copepods. It also showed the highest mean abundance for the entire habitat type. The overall mean density was 194585.1528 ind. m2, with the highest population at station 4. And the lowest population was recorded at station 2. Soft bottom habitat showed the highest recorded mean density among the 5 stations, Harpacticoids mostly dominated sandy substrate while nematodes were widely distributed.Item Life after loss: A phenomenological study of adolescents who lost a parentBahague, April Dawn G. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2016-05)The aim of this phenomenological study was to achieve deeper and broader understanding on the lived experiences of adolescents who lost a parent. Interviews were conducted with six participants, ages 17-19 years old using Interpretative Phenomenological Analysis. The tape- recorded interviews with the adolescent participants were analysed using IPA. The data identified three general themes that reveal the adolescents’ lived experiences: experiencing changes in family pattern, changes in relationship with other people and changes in one’s inner. Findings of the study indicated that the adolescents’ relationship with other family members, relatives and friends or peers provided them with social, emotional and financial support at the time they needed it the most. However, the relationship with this same set of people also caused conflict and other negatively-themed experiences.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 Fungal pathogen associated with Rhizophora stylosa: A comparative study between oiled and unoiled sites within Taklong Island National Marine Reserve (TINMAR), Nueva Valencia, GuimarasBalanga-an, Kristoffer (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2009-03)Mangroves, refer to an assemblage of trees and shrubs that inhabit the coastal intertidal zone in tropical and subtropical regions. They help in the soil formation, protection, and stabilization of our coastal environment as well as serve as shelter and breeding grounds for some of our marine organisms. A mangrove habitat represents the borderline between land and sea and is considered as one of the principal places where spilled oil and associated impacts converge. Oil spill threaten mangroves by predisposing the plants to fungal attacks thereby reducing their resistance to stress and diseases. Studies also show that certain fungi species are able to utilize oil in contaminated mangrove species. This study generally aims to compare the fungal population found on the diseased leaves of Rhizophora stylosa between oiled and unoiled sites in the Taklong Island National Marine Reserve (TINMAR). It also aims to isolate, characterize and identify fungi present in diseased leaves of Rhizophora stylosa using potato dextrose agar (PDA) culture media and determine their frequency of occurrence. Leaf samples were collected from two sites in TINMAR, one of which was contaminated by oil and the other one was not. Three trees were selected to represent each of the two sampling sites (oiled and unoiled), and to each of the selected trees, three diseased leaves were collected. The results of this study showed the dominance of some species of fungi namely, Aspergillus (40%), Penicillium (20%), Cladosporium (13.33%), Monilia (6.67%), Mycelia (6.67%), Humicola (6.67%), and Pestalotiopsis (6.67%). Five out of these seven genera were isolated from the unoiled site while six of these were isolated from the oiled site. Generally, the fungal population was observed to be greater in the oiled site than in the unoiled. This preliminary data indicate that R. stylosa might still be undergoing stress due to the remaining components of the spilled oil in the area. However, this can only be resolved by further monitoring.
