Item Antimicrobial, antioxidant and phytochemical properties of ethanolic and water extracts of selected local spices from Miagao, IloiloBesinga, Yvonne Grace M. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2016-06)Spices such as garlic, pepper and turmeric are indispensable in the daily food preparation and are reported to have compounds which prevent the microbial spoilage of food. This study evaluates the antimicrobial and antioxidant activities as well as the phytochemical properties of the ethanol and aqueous spice extracts of garlic, pepper and turmeric. The antioxidant activity was performed using l,l-diphenyl-2-picryl- hydrazyl (DPPH) Radical Scavenging Method and the antimicrobial activity was evaluated by Disk Diffusion Assay. Phytochemical compounds tested were alkaloids, flavonoids, terpenoids, phenol and saponins. In decreasing order, the potency of the antioxidant activities showed Ascorbic acid > turmeric ethanol extract >pepper water extract> pepper ethanol extract> turmeric water extract> garlic ethanol extract> garlic water extract. The antimicrobial activity was highest in turmeric aqueous extract in terms of mean inhibition zone (7.5±2.10) against E. coli. The most effective treatment against B. subtilis was turmeric ethanol with highest mean inhibition zone (6.87±1.13). And for S. aureus, garlic ethanol extract has the highest mean inhibition zone (7.80±1.32). Phytochemical screening tests showed that in all treatments, the most abundant phytochemical were alkaloids and terpenoids. This study indicates that the spices like garlic, pepper and turmeric have antimicrobial and antioxidant activity.Item Economics of different alternative livelihood projects in Southern Municipalities of IloiloBesana, Nikkei M.; Cang, Marianne S. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2006-03)Poverty incidence in the Philippines is continuously increasing. In line with this the government seeks for opportunities for poverty alleviation. The Food and Agriculture Organization (FAO) of the United Nations in cooperation with the University of the Philippines in the Visayas (UPV) offered different alternative livelihood projects in southern municipalities of Iloilo namely: Tigbauan (shrimp paste making), Miag-ao (salt making) and San Joaquin (fish sauce making). The study described the socio- demographic profiles of the beneficiaries of the projects along with the problems encountered during and after the project implementation. The production processes were also described along with the costs of production. Revenues and profit were derived based on the existing price of the product in the market. Private cost was identified from first up to fourth liquidations. Profit was calculated in every livelihood project and accounted to 728.34 Php for shrimp paste making in Tigbauan, 2,205.54 for salt making Php in Miagao and 1,570 Php for fish sauce making in San Joaquin per individual. Payback period derived was 1.07 that means the initial investment will be recovered in no less than a year. Return on investment was 0.93, which implies that for every peso invested, 1.14 Php returns to the investmentItem Ascariasis and protein energy malnutrition among schoolchildren of Monteclaro Elementary School, Miag-ao, IloiloBerlin, Nellisa Marie; Chua, Enrique III; Daquilenea, Miko; Dorde, Cristy Joy; Hosillos, Juls; Libo-on, Dyann Dolour; Panizales, Katherine Royce; Robleza, Xela Patricia; Sanchez, Maria Lourdes; Sumayo, Marilyn (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2008-04)Ascaris infections lead to malnutrition and poor cognitive development especially to children aged 5-15 years of age. In the Philippines, protein-energy malnutrition is one of the ten leading causes of child mortality. From January to February 2008, a cross- sectional descriptive study was carried out in Monteclaro Elementary School to describe the prevalence of ascariasis and the prevalence of protein energy malnutrition and relate it to the demographic factors such as age group, educational attainment of the mother, annual family income, availability of toilet, and proper hand washing practice. Sixty eight pupils of the said school were included in the study with ages ranging from 6-13 years. Fecal sample of the participants were collected, processed using the Kato-Katz smear technique, and microscopically examined to determine the prevalence of infections. The weight was measured for weight for age index. A self administered questionnaire was given to know about socio-economic factors. Handwashing activities were utilized as a basis for personal hygiene. The result of the study shows that 12% of the study population has a mild A. lumbricoides infection. Weight for age measurement shows that 21% of the pupils are underweight. Pupils of the age group 12-14 were of the highest frequency of ascaris infection and pupils of the age group of 6-8 were of the lowest frequency. Twelve percent of pupils who have toilets in their household are positive for ascaris infection. All pupils failed in the handwashing activity. Twenty seven percent of the pupils whose mothers have no formal education were underweight. This is due to the level of education that the mother has achieved. Mothers who have undergone tertiary education know more about the proper ways to nourish their children thereby minimizing children who are underweight. Twenty-three percent of the pupils included in the study were below normal in the weight for age index. Trend shows that those families with lower income have a higher frequency of respondents that are underweight. For pupils with below normal weight for age 50% are without toilet while 19% with toilet. There is low prevalence of ascariasis in Monteclaro Elementary School. The results of this study do not truly show the relationship of ascariasis with protein energy malnutrition. Inconsistencies of the results with the findings of other studies are possibly due to low number of positive ascaris-infected participants and the low number of overall participants. Increase in the sample size and ascariasis positive participants within the sample are recommended to get more accurate results.Item Acceptability of the newly-formulated food recipes among selected age groups at Brgy. Tabat Tubungan, IloiloBeluso, Heziel F.; Buaron, Michelle Jane A.; Hubag, Angelie Rose C.; Macahilo, Judeilan A.; Mationg, Mary Lorraine S.; Nismal, Myles C.; Pido,Dianah D.; Simaurio, Geraldine C.; Sodusta, Valerie Joy M.; Yasa, Kutch V. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2007-03)This research study is a cross-sectional survey done among 90 conveniently selected residents of Brgy. Tabat Tubungan, Iloilo in order to determine the acceptability of the newly-formulated food recipes based on sensory analysis (appearance, smell, taste and texture), general acceptability, cost, and food action response. The ingredients used in each of the three new recipes namely tortang malunggay, alugbati-squash ukoy and Palawan delight are nutritious, cheap and indigenous to the community. The acceptability test was done among the three selected age groups: school-age children (6-12 yrs old), adolescents (13-19 yrs old) and adult (20-40 yrs old). Pre-tested structured questionnaires were used in the evaluation of the acceptability of the three recipes. Results were analyzed using frequency distribution and test of proportion to determine whether or not the prepared recipes are acceptable. Chi-square analysis was used to test the independence of acceptability of the food items based on the set criteria and the age group categories of the panelists. The results show that three newly formulated recipes namely tortang malunggay, alugbati-squash ukoy and Palawan delight were found to contain high amount of energy content (107 kcal, 181 kcal and 160 kcal) and essential nutrients such as vitamins A and C, calcium and iron which are needed and vital to the body. The percent Recommended Dietary Allowance requirements derived from the three newly formulated food recipes were 5.35% of the total caloric need per serving for the tortang malunggay, alugbati-squash ukoy and palawan delight could supply 9.05% and 8.00% of the total caloric needs. For the sensory test, results show that in terms of the appearance, the three recipes: tortang malunggay, alugbati-squash ukoy and Palawan delight are acceptable to 82.22%, 95.56%, and 84.44% of the panelists respectively. Smell of the three recipes is acceptable to 87.78% of the panelists. Among the ninety panelists, 87.78% and 83.33% said that the taste of the food recipes is acceptable. In terms of texture, tortang malunggay received the highest acceptance level of 88.89%. Based on general acceptability, Palawan delight was liked by 93.33% panelist. The computed Chi-square values show that the acceptability based on sensory analysis and general acceptability of the three food recipes (except the taste of alugbati-squash ukoy) is not dependent on the age group category of the panelists. The costs of the three recipes were also acceptable to 95.56% of the panelists. As to the food action-response, 95.56% expressed a favorable response. Because of the positive results obtained during the acceptability test on the three food items, the researchers recommend these recipes be included in Food Supplementation and Nutrition Education activities.Item The effect of the NFA rice subsidy program "Tindahan Natin" on the political attitudes of its rural poor household beneficiaries in Barangay Caraudan, Janiuay, IloiloBebelone, Diana Mae R.; Fernandez, Charity T. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2009-03)This study described the food security situation in a rural village where an NFA Rice Subsidy Program “Tindahan Natin” is in operation. It analyzes whether or not the Tindahan Natin program (IV) affects the political attitudes (DV) of its rural poor household beneficiaries. The research assessed the various levels of external political efficacy, political cynicism, political trust, and cynical statism of thirty-three (33) rural poor households (16 non-beneficiaries and 17 beneficiaries) in Barangay Caraudan, Janiuay, Iloilo. The study employed the Quasi-Experimental Method, specifically the Nonequivalent Control Group Design (NCGD). Using the non-probability purposive snow-ball sampling technique, a survey was conducted which assessed the sociodemographic profile of the respondents and measured their levels of political attitudes through Likert-Scale statements. Results show that the “Tindahan Natin” program by the government has been effective in increasing the accessibility and availability of basic food resources— specifically rice—in Barangay Caraudan. The levels of political trust among the beneficiaries of the food subsidy program is a a little bit higher compared to the nonbeneficiaries, which means that the government program has possibly strengthened the positive attitude and outlook towards the government, its institutions, and bureaucracy in general. All rural poor household respondents are highly cynical towards the government and the elected leaders and politicians. A substantial majority—regardless of being a beneficiary or a non-beneficiary of the Tindahan Natin—are highly dependent on the government’s provision of public services addressing food insecurity. There is no difference in the respondents’ assessment of the responsiveness of the government.Item Worldview, life aspirations and quality of life of visually impaired children of SPED Integrated School, Iloilo CityBedia, Nadine Grace D.; Petrola, Mary Anne G. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2009-03)A large number of the Philippine population has visual impairment problems and many of them are children. The study explored on the worldview, life aspirations and quality of life of visually impaired children. Five (5) visually impaired children aged 11-18 years old who studied at SPED Integrated School, Iloilo City were the participants of the study. Using a descriptive and phenomenological approach, the visually impaired children were purposively selected to answer the interview guide. Findings show that children under study came from nurturing homes and they get different reactions from their peers when they were mainstreamed unlike that when they are inside the SPED classroom. Also, they regarded some life aspirations to be important but the likelihood of attaining these goals was low. Generally, these children have moderate to good quality of life. Their level of superiority is low, thus, they have this feeling of inadequacy.Item Decision making in the practice of birth control in a rural communityBarrios, Ritchie P. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1992-07)This is a study on the decision-making pattern of couples in the use of birth control in a rural community. The study sought to determine: 1. Who the decision-maker is in the couple structure: 2. how the decision to practice was reached by them and 3. what are the basis for the choice of a particular birth control method. Based on the findings it was concluded that for the couples in Brgy. Tuburan, Pototan, Iloilo it was both the husband and the wife who decided that they will practice birth control. This is contrary to the popular notion that it is the husband who decides. It was also found out that the midwife who was at the same time the family planning implementor, played a major role in the decision to practice birth control. Having reached the decision to practice birth control, certain considerations like convenience, effectiveness, no side effects, etc. were taken by the couples in the selection of the method to adopt. It was however found out that the final choice of the method to be used was made by the family planning implementor. It is interesting to note, however, that in the barangay only forty-one couples out of the one hundred seventy have or are practicing birth control. This is attributed to the fact that the family planning implementors failed to get the message across to a larger audience. The mothers' class which was used as a strategy to attract couples to take interest in family planning failed to reach large segment of the population.Item Isolation and partial characterization of globulin from Cassava (Manihot esculenta Crantz) tubersBarbosa, May R. (Division of Physical Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2007-04)Soluble globulin was isolated using an extraction buffer (0.4 M NaCl in 35 mM potassium phosphate buffer, pH 7.6 with 0.02% Na azide). The isolated globulin was subjected to solubility tests with different NaCl concentrations. It has the highest solubility in 1.25M NaCl (1.09%), but no significant differences existed among the NaCl concentrations by analysis using one-way ANOVA at a = 0.05. Three major bands existed at LOOM NaCl dissolved globulin with molecular weight ranges of 28-33kDa, 38- 43kDa, and 65-70kDa relative to BSA. Two of these bands (38-43kDa and 65-70kDa) were observed in 0.50M and 0.75M NaCl soluble globulin. The 1.25M and 1.50M NaCl concentrations gave a single band (28-33kDa) each, while no clear bands were observed in other NaCl concentrations. Amino acid analysis revealed glutamic acid (12.09%) as the most abundant amino acid component of cassava globulin. Nine (9) essential amino acids were present. Of these nine, lysine (10.50%) is the most predominant. Cystine (0.39%) has the lowest percentage, followed by methionine (1.76%).Item Gonadal maturation Stages of Pinkfingered Vinegar Crab Episesarma chengtongense (Serene and Soh 1967) from Capiz, PhilippinesBarredo, Elilyn Farrah Belle B. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2015-06)The pink-fingered vinegar crab Episesarma chengtongense is a growing fishery resource in the mangrove areas of the Philippines and may have potential for aquaculture and stock enhancement. To determine the gonadal maturation stages for both male and female for this species, a study was conducted from February to May 2015 of the pink-fingered crab from Capiz, Philippines. The determination of the gonadal maturation stages was based on the gross morphology and histological characteristics of the male and female gonads. In both sexes, gonad activity occurred throughout the study duration but for females, the peak egg bearing month was in May (87%). Body sizes of ovierous females were from 31.9 - 42.3 mm (CW). The greatest prevalence of ovigerous females was in the size range of 35-39 mm CW; the lowest percentage at 40-44 mm CW. Male crabs with mature testes were consistently high (70- 100%) in the four months duration of the study. The smallest female carrying eggs was 31.9 mm CW. Four stages of ovarian maturation were identified namely: developing (Stage II) with a yellow colored gonad, ripe (Stage III) with orange colored gonad, mature (Stage IV) with brown colored gonad and spent (Stage V) with light brown colored gonad. Two stages of male gondal maturation were identified namely immature (Stage I) with translucent to off white testes and mature.(Stage II) with creamy white testes.Item Economic cost of dengue fever treatment in Miagao, IloiloBanehit, Gracesel Faith D.; Napulan, Macie Carlyn A. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2017-06)Dengue, the most rapidly spreading mosquito-borne viral infection in the world, has caused many deaths in the Philippines. The municipality of Miagao, Iloilo Province, has recorded a high number of dengue cases in recent years. This study determined the economic cost of dengue fever treatment among affected households and patients with dengue in 2016 in Miagao. The study used a cross-sectional data collected from 169 interviews with the study participants for 201 dengue patients from 62 barangays in Miagao in February to April 2017. The study identified, measured, and valued the various costs related to dengue fever treatment. Results showed that the total economic cost for home-treated patients averaged at Pl2,522.08 for both the patient and the caregiver (household), with the following breakdown: P5,068.82 for monetary costs (direct medical and non-medical costs) and P7,453.26 as opportunity cost. For those who were admitted in the hospital, the total economic cost averaged at P22,213.31 with the following breakdown: P9,504.77 for monetary costs and P12,708.54 for opportunity cost. As expected, patients treated at home had lower costs both in monetary and nonmonetary aspects compared to those confined in the hospital. Although the majority of the study participants are knowledgeable about dengue, it is still necessary to increase their awareness of dengue prevention in order to prevent dengue treatment costs for the households. The local government must also strengthen the implementation of its existing dengue prevention policies and programs to mobilize cooperation and involvement of the people in dengue prevention.
