Item The health status of school-age children in Barangay Ingore, La Paz, Iloilo CityAmamanglon, Keanne Paula H.; Bragancia, Ira May Joy E.; Gulmatico, Gideon M.; Guzman, Virgi Chrisbelle A.; Mercado, Pauline Victoria M.; Orbase, Jannina Faye O.; Reyes, Mary Camille E.; Yap, Maria Lorna Christy C. March (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2011-03)The study is a cross sectional survey to assess the health status of school-age children in barangay Ingore, La Paz, Iloilo City. The health status of the children was evaluated using nutritional status assessment, child care practices of mothers/caretakers and past and present clinical history of disease, and respiratory function. Anthropometry and Clinical Signs were used to directly assess the nutritional status of the children. An Interview Schedule, with mothers/caretakers as respondents was used to determine the socio-demographic characteristics of the household to where the children belong and also to obtain information on their child health care practices. Respiratory or Lung Function was assessed using Lung Peak Flow and Chest Expansion. The results of Anthropometry using the parameters for Weight-for-Age (WFA), Weight-for-Height (WFH) and Height-for-Age (HFA) revealed that 16.3% of the school-aged children were underweight; 10.7% were thin or wasted; 24.4% were stunted, and 4.0% were overweight/obese. The most common clinical signs indicative of malnutrition were pale conjunctiva and the occurrence of dental carries. Most of the children have been breastfed and availed of complete immunization during their pre-school age period. Almost half of them experienced childhood diseases like upper respiratory tract infections (e.g. cough, common colds, asthma, etc.). Peak flow analysis showed that among male, school-age children the average peak flow was 210.6L/minute while among female it was 195.7 L/minute. The computed average peak flow was 203.2 L/minute. The average chest expansion of the subjects was 2.4 cm and the chest expansion of male and female school-age children was 2.4 centimetres. The results obtained in this study can be used as a baseline for future studies especially in the light of the recent operation of a coal-fired power plant which might affect the health status of vulnerable age groups like pre-school and school-age childrenItem Cost and return analysis of van operation in the Municipality of Miag-ao, IloiloAlvizo, Marjorie V.; Laura, Cecille R. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2003-03)Generally, this study aimed to evaluate or assess the profitability of van operation in Miag-ao, Iloilo. It specifically dealt with the cost and return structures of the said business. The study was conducted in the municipality of Miag-ao, which is one of the towns in the province of Iloilo. There were 11 respondents who are all van operators and at the same time members of the Miag-ao Association of Van Owners and Drivers, Inc. (MAVAD). Two of them owned or operate two vans, so in the data presented there were 13 vans. A one-shot survey using recall method was used as a source of data. An interview schedule was also utilized in gathering the needed data for the study. In analyzing the data, frequency distribution, percentage, ranking and weighted mean were employed. Likewise, cost and return analysis was used to determine the profitability of the van operation. Results of the study showed that almost half of the respondents have an age range of 30-40 years. Majority (73%) of them were males and already married. All van operators earned college degrees and have well-paying jobs. Roman Catholic was the dominant religion and most of them have or belong to medium family size. The cost and return analysis of the study showed that the average initial investment in the van operation was P 238,000. The total annual operating cost was P 434,366. Forty nine percent of it was paid for the salaries and allowances of the laborers. The annual gross revenue was P 505,210 with a net income (or pure economic profit) of P 70,844. Rate of return on investment was 30% and it will take 3.4 years for the business to recover its initial capital outlay. Based on the results presented, with positive net profit and gross revenue it is profitable to engage in this business venture.Item The role of women rebel returnees in the armed conflict and transformation politics in Leon, IloiloApatan, Mildred V. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1998-03)The study focuses on the role of the women rebel returnees in the armed conflict and transformative politics in Leon, Iloilo. Descriptive in nature, it pioneers in the study of women rebel returnees in the region. It has the following objectives: to determine the reasons of the women rebel returnees for joining the insurgency movement, to determine the nature of their political participation and role in the ai med conflict, to identify the reasons which brought them back into the mainstream of society, and to describe the role they played in transformative politics. The method used in gathering the data was personal interview with an interview guide. Also, a questionnaire on their socio- demographic profile was provided. The study found out that, in general, the women rebel returnees joined the insurgency movement for social reasons such as influence of those who were already members of the movement. Their role inside die movement was mostly reproductive in nature, that is, works that deals mostly with or involves their comrades and the movement. Their reasons for leaving the movement were also socially motivated. Their participation in transformative politics is also reproductive in nature and that their positions in various organizations and institutions belong to a relatively upper level. Their problems are mostly financial and could be addressed by giving them more projects, opportunities, and network with other women's organizations.Item Effects of high and low protein diets on the gut evacuation rate of Tilapia niloticaAndrada, Bryan Andrew S. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1999-03)Gut evacuation rate of young Nile tilapia, Tilapia nilotica fed commercial pelleted diets containing high or low protein diet were determined in the laboratory. The decline in gut fullness of the fish with time was examined at low and high protein diets. Two mathematical models were used to express the decline in gut fullness of the fish with time. Fish fed the low protein diet followed more closely the linear model while those fed the high protein diet followed the logarithmic model. The level of protein resulted in different gut evacuation rates (GER), expressed as coefficients b of the gut fullnesstime curve. GER values were higher in either linear or logarithmic models for fish fed low protein diet than for those fed high protein diet.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 Risk zone mapping of 2010 dengue fever and dengue hemorrhagic fever cases in the Province of Iloilo based on land coverAndrada, Thresdale; Cañonero, Gertrude Mikee; España, Regine Marie; Puno, Abigail; Sarangaya, Dorothy Rose; Tan, Leonard; Tejada, Ma. Corazon (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)Dengue is considered as one of the most important vector-borne diseases in many tropical and subtropical countries. Iloilo Province had 8201 cases in 2010. Heterogeneity in the risk of disease transmission results from spatial heterogeneity in both land use and land cover. Thus, the present study was conducted to identify the risk zones of Dengue Fever and Dengue Hemorrhagic Fever in Province of Iloilo in 2010 based on land cover types by using GIS software. Results of the study show that all land covers in the 6th district pose moderately low risk on dengue incidence. In the case of the 1st district of Iloilo, on the other hand, water bodies have the highest probability of dengue incidence, while the rest of the districts (2nd, 3rd, 4th, 5th). built-up areas have the highest probability of dengue incidence. The land cover type in Iloilo, therefore, with the highest risk for dengue incidence are built up areas due to its high population density, multitude of households and stagnant water areas.Item Removal of Harmful Algal Bloom (HAB)-forming organisms using ball clay: Factors and effects of clay additionRivera, Peter Paolo L. (Marine Science Institute, College of Science, University of the Philippines Visayas, 2015-05)Global concern for Harmful Algal Blooms (HABs) has increased due to their frequency of occurrence and associated negative health and economic effects. Control measures for HABs/red tides have been developed to alleviate their effects in the marine and coastal environments. The use of clays and modified sands/sediments to remove/control HABs is one of the promising and attractive direct control options for areas with persistent HAB problems. However, factors such as pH and ionic strength and mechanisms and kinetics of algal removal through clay addition/spreading are not fully understood. This study examined the effect of different pH levels and varying ionic strength on the removal efficiency (RE) of ball clay on toxic dinoflagellates: Pyrodinium bahamense var. compression, Gymnodinium catenation, and Alexandrium tamarense complex. High REs by ball clay were observed on Pyrodinium and Gymnodinium. On the other hand, only minimal removal was observed with Alexandrium. This implies that ball clay has a varying affinity towards different HAB species. Removal was also found to be highly dependent on bloom stages and varies for a given target species. RE of ball clay for the three test organisms increases as the pH of the solution decreases (83.1% for Pyrodinium, 81.2% for Gymnodinium, 89.4% for Alexandrium at pH 6. Results from this study show that with increasing salinity and/or ionic strength, RE also increases (82.7% for Pyrodinium, 88% for Gymnodinium, and 79.5% for Alexandrium at ionic strength of 1.0). Results show that changing the pH and ionic strength influenced the zeta potential (electrokinetic potential) of both the toxic algal cells and ball clay, hence affecting algal flocculation and leading to the effective removal of the algal cells. Microalgal cells are negatively charged in growth media at pH values (7-9 for most algal species) typical for growth and the charges cause adjacent cells to repel each other and remain suspended in the medium. The negative charges apparently derived from the water and dissociation of functional groups on algal cell walls, and vary among different algal species. The changes in pH influence the degree of surface dissociation, thus affecting the cell surface charge. The zeta potential of ball clay as a function of varying ionic strength and salt concentrations showed that zeta potential decreases (more negative) with increasing ionic strength from 0 to 1 and/or salinity from 0 to 36 ppt (in contrast to algal cells). When the ionic strength of the solution is increased, the charge potential difference between clay particles and algal cells also increases, thereby increasing the affinity between the two particles. Cell death and lysis were evident within the suspended and settled clay matrix from direct microscopic observation. The cells appeared moribund, and stained cytoplasmic material could be seen leaking into the medium. Cell death may have been due to the direct physical contact between the cells and clay particles. Cell lysis occurred over a 1–2-hour period in single-species cultures of HAB organisms. Measurement of fluorescence properties through confocal laser scanning microscopy (CLSM) of microalgae has proven that a rapid and sensitive ecotoxicity method could be developed where the motility and viability of cells flocculated with clay could be examined. The substantial release of the nucleotides and intracellular materials from the algal cells indicates the expulsion of the thecal plates and cell membrane leading to the disintegration of the algal cells upon clay addition. Cellular damage was further confirmed by metabolic imaging through an esterase activity assay. Esterase activity in control and treated cells was studied by fluorescence imaging after staining with fluorescence diacetate (FDA), a technique to probe cell membrane integrity and cell viability. FDA-positive cells decreased through time until 24-hour upon exposure to ball clay. Future studies are needed to investigate the actual mechanism of how clay induces cell lysis or mortality. Cell mortality may be due to natural senescence or programmed cell death (PCD) under stress-promoting conditions and not related to any chemical or physical interaction between the clay and the algal cells. It is also interesting to look at the possible formation of ecdysal and temporary pellicle cysts upon clay treatment. The possible formation of temporary cysts by HAB cells may play a role in bloom regrowth. The encystment and excystment may enable HAB cells to escape entrapment, allowing a bloom to reform.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.Item Dengue knowledge, policies, and Aedes Larval population in selected low and high dengue priority areas in Miagao, IloiloAmihan, April Rose D.; Basco, Arriane Mae P.; Escosia, Edmon B.; Monsale, April Joy P.; Solis, Jann Christian V.; Varon, Marianne Joy C. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2009-03)This cross-sectional study aimed to compare the knowledge, practices, and Aedes larval populations between low and high dengue priority areas of Miagao, Iloilo. Questionnaire-guided interviews were conducted to assess the knowledge and practices of the study population. Larval surveys were done to determine Aedes larval populations, expressed as House Index (HI), Container Index (CI), and Breteau Index (BI). Results showed that respondents from the low priority area were more knowledgeable on dengue than the respondents from the high priority area (p<0.05). Dengue preventive practices were found to be the same for both low and high priority areas. There was, however, no significant relationship between dengue knowledge and dengue preventive measures (p<0.05). Results from (he larval survey revealed that both low and high priority areas have HI and BI above the WHO standards (HI<5%; BI<20) and are considered “high risk” areas. Lastly, age (p<0.01) and educational attainment (p<0.05) were found to affect an individual’s dengue knowledge.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.
