Item 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 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 Community structure of mangroves in selected barangays in Sebaste, AntiqueAlorro, Mary Juandin Grace F. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2007-03)Mangroves are higher plants that are primarily found predominantly in the intertidal areas such as estuaries and lagoons of the tropical and subtropical shorelines. This study was conducted to assess the community structure of mangroves in Barangay Callan, Barangay Idio, Barangay Poblacion, Barangay Abiera, and Barangay Bacalan, Sebaste, Antique, using the transect line method. Specifically, it aimed to determine selected physical and chemical factors such as salinity, pH, temperature for water and soil as well as characterization of the substrate; identify and classify true mangrove species present in the area; and describe the community structure in terms of stand basal area, stems per hectare, relative density, relative frequency, relative dominance, importance value, Shannon index of diversity, zonation patterns, seedling and sapling density. No study has been done to document the community structure of mangroves in Sebaste, Antique thus, this study was done to provide vital information needed for its proper management. Three stations were selected in Sebaste, Antique. Four (4) species of true mangroves were identified, belonging to three (3) families: Palmae - Nypa fruticans; Rhizophoraceae - Rhizophora apiculata, Bruguiera gymnorrhiza; and Euphorbiaceae - Excoecaria agallocha. The study area had a water salinity range of 0.6 ppt to 15.3 ppt; water temperature range of 28.3°C to 35.4°C; water pH range of 7.1 to 7.7; soil temperature range of 28.3°C to 34.7°C; and soil pH range of 6.5 to 7.2. Basal area ranges from 3.16 m2/ha (Rhizophora apiculata) to 5.88 m2/ha (Excoecaria agallochd) to 8.19 m2/ha (Bruguiera gymnorrhiza) . The species with the highest average of stems per hectare were Excoecaria agallocha and Bruguiera gymnorrhiza with 300 as well as the highest average density value of 100 for Excoecaria agallocha. Nypa fruticans had the highest relative frequency and relative dominance. Among the four species, the most important species was Nypa fruticans. The Shannon Index of Dominance was 0.403 which was quite low in terms of diversity as influenced by the dominance of Nypa fruticans.Item Gross alpha and gross beta radioactivity and heavy metal concentration profiles of well water of the Calahunan dump site, Mandurriao, Iloilo CityAmarante, Hena Charma; Basquez, Mark Anthony; Brunio, Christian Allan; Dable, Nesel; De la Pena, Pamela-Di; Genterola, Janis; Oredina, Josette Marie; Padayhag, Dave (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2005-03)The study aimed to establish presence of radioactivity and concentration of heavy metals specifically lead and chromium in drinking water from wells within one-kilometer radius from the approximated center of the Calahunan dump site. Results showed that four out of twelve wells have positive results fro gross alpha activity and gross beta activity: wells 2A, 2C, 3A, and 3D. Well 2A, 2C and 3D registered alpha activities of 0.54, 0.033 and 0.369 Bq/L respectively while Well 3A registered beta activity of 1.0 Bq/L. Wells 2A and 3D exceeded the radiological limits set by WHO and PNSDW of 0.1 Bq/L for alpha activity and 1.0 Bq/L for beta activity. These wells that are found adjacent to the perimeter fence of the dump site registered alpha activity (wells 2A, 2C and 3D) and beta activity (well 3A). Radiological activities in all other wells sampled registered less than lower limit of detection. For gamma activity, all wells recorded 137- Cs and 134-Cs activity less than the lower limit of detection. For chromium and lead concentration using FAAS, only well 3C has a chromium concentration of 0.0952 ppm and this exceeded the PNSDW standard for chromium in drinking water (0.05 ppm) FAAS has not recorded any value for lead. For chemical constituent analysis using XRF, two wells in zone 1 (LA and IC), have recorded lead concentration of 0.9 and 0.136 ppm, respectively. In zone two, only well 2D registered a lead concentration of 0.248 ppm. In zone 3, well 3C registered a lead concentration of 0.397 ppm. For chromium concentration, only well 2A in zone 2 has a chromium concentration of 1.79 ppm. The spot interview and ocular inspection found out that the following garbage are disposed of indiscriminately tn the dump site: (1) Television picture tubes, (2) Dysfunctional Computer Monitors, (3) Used syringes and needles, (4) Hospital wastes, (5) Automobile batteries and dry cells, (6) scrap iron, tin cans, paint cans, paint cans, etc., (7) polyethylene bottle, glass bottles, and containers of similar types, and (8) other organic and inorganic wastes. Wells whose values for gross alpha, lead, and chromium concentration exceeded the standard are unsuitable for dinking and other domestic uses. The observation that wells (2A and 3D) near the Calahunan dump site registered higher-than-standard alpha activity may be a good basis to conduct further research particularly on the effect of leachate from dump site.Item Fourier transform -infrared-attenuated total reflectance spectroscopy in conjunction with the principal component analysis and agglomerative hierarchical clustering to classify virgin coconut oil and other edible oilsAloba, Eugene J. (Division of Physical Sciences and Mathematics, College of Arts and Sciences, University of the Philippines Visayas, 2006-04)This work investigates the potential of Fourier Transform Infrared-Attenuated Total Reflectance (FTIR-ATR) Spectroscopy in conjunction with Principal Component Analysis (PCA) and Agglomerative Hierarchical Clustering (AHC) to classify virgin coconut oil (VCO) from other different edible oils in the test set. Among the PCA types, Pearson produced the best biplot graphs that showed both the separation of VCO and coconut oil (only in one group) from other oils, and the separation of VCO and coconut oil (CCO) into two distinct groups using the fingerprint region of the spectra. Kendall dissimilarity/Ward’s method successfully clustered VCO and CCO as separate classes using the same region of the spectra. These results showed that the highest percent variability in the spectra of different oils occurs in the fingerprint region, and hence where spectroscopic classification of oils can be performed best.Item Perceived body image of female college studentsAlmonte, Darby April Gaye Q.; Tinsay, Shiela Mae B. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2003-03)The study aims to describe the perceived body image of female college students. Specifically, it wants to find out the activities of female college students relative to their body image; their exposure to the mass media in terms of enhancing body image; and to find out the influence of mass media exposure to their perceived body image. The study was conducted in the College of Arts and Sciences, University of the Philippines in the Visayas, Miag-ao, Iloilo. Sixty respondents were obtained from the population of Social Sciences students using the fishbowl method of simple random sampling. The Body Parts Satisfaction Scale (Spainhour, 2000), together with a set of questions developed by the researchers, were used in gathering the data. Generally, the results showed that the female college students have a positive perception of their body image. Also, the female college students do not engage in any activity related to body image, such as dieting and exercising. Lastly, they are well exposed to the mass mediated messages about body image in the television and the magazine but they are not negatively influenced by those messages, that is, they neither compare their bodies with nor do they want to look like the models in television and magazine.Item The dynamics of going legitimate and running for Barangay position among rebel returnees in Leon, IloiloAllones, April Joy G.; Fillaro, Geraldine M. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2005-03)This study explains the process of going back to the mainstream of society of former rebels and their political participation in the barangay politics. Descriptive in nature, it has the following objectives; first, is to identify the social climate and political recruitment patterns (reasons, mindset, and community situation) of rebel returnees; second, is to identify the resources from national or local politicians and “partido”, who endorsed the rebel returnees; third to identify the factors behind the success or failure of rebel returnee candidates in barangay elections. The method used in gathering of the data was personal interview with an interview guide. The study found out that in the recruitment, selection and election patterns of individuals, whether a private individual or a rebel returnee, several factors are considered before the people decides who they wanted to vote. Personality traits, kinship ties and political machineries are always important to dominate local or national politics in the Philippines. Motivation and political were also popular reasons for winning the elections. Inspired and influence by the doctrines of the underground movement, the rebel returnees joined politics due to their strong conviction to effect changes they had been advocating ever since. But, their rebel background had been a setback for their election into public position. They refused endorsement from local partidos for they believe and adhered to their genuine cause of fielding themselves in politics without political backings. Some of these rebel returnees succeeded in their quest for barangay position and some did not. The success and failure of each rebel returnees had been determined by varying factors present in the society.Item Television viewing patterns of children in a rural communityAllones, Christine Marie G; Montalvo, Nica M. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2007-03)The general objective of the study is to find out if there is a relationship between TV viewing patterns of children in a rural community and the socio-demographic characteristics such as age, sex, and the parents’ educational attainment. Specifically, it aims to (1) describe the socio-demographic profile of the respondents; (2) determine if there is a relationship between children’s age and their TV viewing pattern; (3) determine if there is a relationship between children’s sex and their TV viewing pattern; (4) determine if there is a relationship between parents’ educational attainment and TV viewing pattern. The data analyzed in this study are obtained through conducting guided interviews with 80 children. The areas included by the researchers in the study are the hours and days of TV viewing of children, their program preferences, their sleeping time, and the frequency of scolding of the parents. It was found that majority of the respondents are 10-12 years olds, males, and have parents who have both high educational attainments. Results reveal that majority of respondents spend between one to five hours watching television everyday. Their usual sleeping time is before or at nine in the evening. Nonetheless, many are scolded for watching television on weekdays but never on weekends. The results of the study concluded that there is a significant relationship between sex and hours of television viewing while age and parent’s educational attainment have no significant relationship in the hours of television viewing. There is no apparent difference between the number of hours of television viewing and the age and parent’s educational attainment. The only difference is that majority of male children watch television for one to five hours a day, while most female children watch more than five hours of TV viewing. Thus, there is a significant relationship between sex and hours of television viewing. On the other hand, there is no significant relationship between the days of TV viewing and the socio-demographic characteristics of the respondents. The researchers recommended that a similar study could be conducted in an urban area, covering a bigger sample size, and using other set of variables that can affect the TV viewing patterns of children. Other researchers are also encouraged to explore the field since there are not so many studies about them in the country.Item Sodium and potassium concentration ratio in mangrove leaves as sublethal indicator of oil stress in mangrove trees, Taklong Island National Marine Reserve (TINMAR), Nueva Valencia, GuimarasAlianza, Carmen Gabrielle H. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2009-04)This study is in the second year of the five-year research that was assigned to UPV to monitor the effects of the oil spill in TINMAR. This research primarily focuses on the Sodium and Potassium ion concentration ratios in the leaves of the mangroves which will be used as sub-lethal indicators of oil stress in the mangrove trees. Specifically, this study determined the total amount of Sodium and Potassium ions present in the mangrove leaves using Flame-Atomic Absorption Spectrometer, compared the Potassium and Sodium ion concentrations among the different species and between sampling sites and determined the sensitivity of the species based on the changes in Na/K ratio. Results showed that the total Sodium concentrations were within the values under normal conditions except for Rhizophora apiculata and Rhizophora mucronata and the total Potassium concentrations were also within the values under normal conditions except for the Sonneratia alba species in Bagatnan. The Na/K ratio determined the sensitivity of the mangrove species studied to oils stress. A lower ratio of Na/K compared to the control area means that the mangroves trees were able to cope up with stress and an elevated Na/K ratio means the mangrove trees are still undergoing stress. The Control area, however, have elevated Na/K ratio because of high Sodium concentrations and very low concentrations of Potassium in the plant leaves tissues.Item Waist-to-hip ratio, body mass index and hypertension among adult in the San Rafael Catchment Area in Miagao, IloiloAlfabeto, Ace Robert; Anglopez, Mae Therese; Arzaga, Rhodora; Jocsing, Christy Joy; Sandoy, Rovi Floresa; Tan. Louie Lito (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2009-03)A cross sectional study was conducted among 169 randomly selected adults of selected barangays served by the San Rafael Health Center in Miagao, Iloilo. The study determined the relationship of anthropometric measures Body Mass Index and Waist to Hip Ratio with hypertension. Several biological and socio-demographic variables including age, physical activity, family history, family income, smoking and alcohol consumption were studied to determine their possible association with hypertension. These were analyzed with binary logistic regression for their possible association with hypertension. The prevalence of hypertension in the San Rafael Catchment Area was found to be 47.3%. This value is greater than the 22% national prevalence obtained in the 6th National Nutrition Survey of Filipino adults in 2003-2004. A higher prevalence of hypertension was found to be higher among males (51.4%) than in females (44.2%). the prevalence of hypertension obtained using BMI as an indicator of overweight and obese individuals was 51.2%. On the other hand, the prevalence of hypertension using WHR as a measure of android obesity was found to be lower (45.6%). Based on analysis with binary logistic regression, none of the confounding factors (sex, age, family history, physical activity, smoking and alcohol consumption) was significantly associated with hypertension. Body Mass Index was used in the study to identify those who were overweight and obese and Waist to Hip ratio to identify those who had android obesity. Based on body mass index, the prevalence of overweight and obesity was found to be 15.38%. The prevalence of android obesity based on Waist to Hip Ratio was found to be 40.24%. Body Mass Index was positively correlated to SBP but not to DBP based on analysis by linear regression. However, low R squared values show that BMI is a poor indicator for hypertension. Likewise, WHR was positively correlated to both SBP and DBP by linear regression, but was also found to be a poor indicator of hypertension. The results obtained recommend further study in the San Rafael Catchment area. The prevalence of hypertension and android obesity are found to be much higher than national statistics. However, no significant relationship between the anthropometric measurements and hypertension could be drawn from the present study.
