Item Comparison of direct microscopy and concentration techniques using household bleach for the detection of acid-fast bacilli in sputumBernabe, John Marvin S.; Biaoco, Beverly G.; Castillanes, Melvic A.; Fernandez, Ia Jean F.; Geraldoy, Ruffa V.; Molina, Ryge Albert D.; Pluma, Zyra April D.; Que, Agnes Karen B.; Servidad, Mercy Jeane C.; Tamayo, Kyria Mae Marre P. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2008-03-29)Several published studies have demonstrated that the sedimentation and centrifugation concentration techniques which utilize sodium hypochlorite are more efficient in detecting acid fast bacilli in sputum smears compared to the conventional direct smear method. This study was conducted to (1) compare the proportion of AFB-positive samples by direct microscopy with the household bleach centrifugation concentration technique; (2) compare the proportion of AFB-positive samples by direct microscopy with the household bleach sedimentation concentration technique;(3) compare the proportion of AFB-positive samples by household bleach sedimentation with the centrifugation concentration techniques; and (4) compare the cost of the direct smear method, centrifugation concentration technique, and sedimentation concentration technique for detection of AFB. Sputum specimens were collected from TB-DOTS clinics in Miag-ao and San Joaquin, Iloilo and from Medicus laboratories in Iloilo City. The specimens were then processed through the direct smear method, centrifugation concentration method, and sedimentation concentration method. Out of 174 sputum samples included in this study, results revealed that (1) there was no significant difference in the proportions of AFB-positive slides detected using the direct microscopy and centrifugation concentration technique; (2) there was no significant difference in the proportions of AFB-positive slides detected using the direct microscopy and sedimentation concentration technique; (3) there was no significant difference in the proportions of AFB-positive slides detected using the centrifugation and the sedimentation concentration techniques; and (4) simple cost analysis of the three methods suggests that the direct smear method is the most cost efficient. The findings indicate that whichever method is used would yield almost the same proportions of AFB-positive slides. Internal quality control should be maintained throughout the laboratory work to obtain reliable results, as it is the manner of processing that determines the outcome of this study and its validity.Item The community structure of mangroves in Ivisan, CapizBermoy, Gian Carlo A. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2004-04)The structure of the mangrove community in Ivisan, Capiz was studied using the transect line plot method with fifteen plots established. This study aims to assess the community structure of mangroves in Barangay Agustin Navarra and Barangay Balaring, Ivisan, Capiz using accepted ecological indicators. Community structure is described in terms of the following parameters: basal area, stems per hectare, relative density, relative frequency, relative dominance, importance value of the species, and the Shannon Index of Diversity. Variations in these parameters are correlated with certain physico-chemical factors such as air and water temperature, soil pH, and water salinity. Little study has been done to document the mangroves in Barangay Agustin Navarra and Barangay Balaring, Ivisan, Capiz. This is the first systematic study done in the area; thus, the present study will provide vital information needed for its proper management. A total of nineteen true mangrove species represented by ten families were identified on Barangay Agustin Navarra and Barangay Balaring, Ivisan, Capiz. The true mangroves consisted of Aegiceras corniculatum, Avicennia alba, Avicennia marina, Avicennia officinales, Avicennia rumphiana, Bruguiera cylindrica, Bruguiera parviflora, Camptostemon philippinensis, Ceriops decandra, Exoecaria agallocha, Nypa fruticans, Osbornia octodonta, Rhizophora apiculata, Rhizophora mucronata, Rhizophora stylosa, Sonneratia alba, Scyphiphora hydrophyllacea, Xylocarpus granatum and Xylocarpus moluccensis. All the species were present in Station 1 except Scyphiphora hydrophyllacea. The species present in Station 2 and in both stations were Avicennia marina, Avicennia rumphiana, Exoecaria agallocha, Osbornia oclodonta, Rhizophora apiculata, Rhizophora mucronata, Scyphiphora hydrophyllacea, and Sonneratia alba. Avicennia marina has the overall highest relative density of 340 trees per hectare, relative frequency of 22%, relative dominance of 266.655%, and importance value of 628.841%. Seedlings and saplings of Avicennia marina dominate the area indicating that the mangrove community is young and regenerating stand. Barangay Agustin Navarra has the highest index of diversity of 0.87 while Barangay Balaring has an index of diversity of 0.47. The overall index of diversity is 0.674.Item Community structure, biomass productivity and carbon stock assessment of mangroves in Barangay Tabon, Batan Bay, AklanBermeo, Ma. Ramela Angela C. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)The study aimed to assess the community structure, biomass productivity, and carbon stock assessment of mangroves in Barangay Tabon, Batan Bay, Aklan using the plot method. Specifically, it aimed to: 1. determine selected physical and chemical factors such as water salinity, water pH, soil temperature and characterization of soil substrates, 2. identify true mangrove species present in the area, 3. 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 Pattern, Seedling and Sapling Density, 4. assess the biomass productivity (both wood biomass, and litter fall), 5. estimate the amount of carbon stored in the mangrove forest (using allometric equation). A total of twenty-one true mangrove species belonging to 12 families were identified. Family Rhizophoraceae was the most represented with five species namely Bruguiera cylindrica, Ceriops decandra, Rhizophora apiculata, R. mucronata, and R. stylosa. The rest were also well represented namely Family Avicenniaceae- Avicennia alba, A. officinalis, A. marina, and A. rumphiana; Family Combretaceae- Lumnitzera littorea and Limnutzera racemosa; Family Sonneratiaceae- Sonneratia alba, and Sonneratia caseolaris; Family Acanthaceae- Acanthus ebracteatus; Family Bombacaceae- Camptostemon philippinensis; Family Euphorbiaceae- Excoecaria agallocha; Family Meliaceae- Xylocarpus moluccensis; Family Myrsinaceae- Aegiceras corniculatum; Family Myrtaceae- Osbornia octodonta; Family Arecaceae- Nypa fruticans; Family Rubiaceae- Scyphiphora hydrophyllacea. Basal area ranged from 0.11m2/ha for Ceriops decandra to 68.78m2/ha for Sonneratia alba. Avicennia marina had the highest stems per hectare with 22,600 stems/ha, while Bruguiera cylindrica had the lowest with 100 stems/ha. Avicennia marina occurred in all plots with 137 trees/ha and had the highest relative density of 38.38% and relative frequency of 38.42%. Sonneratia alba had the highest relative dominance of 48.49% while the lowest was Ceriops decandra with 0.08%. Avicennia alba, Bruguiera cylindrica, and Ceriops decandra had the lowest relative densities and frequencies at 0.3%. The most important species was Avicennia marina (107.6) and the least important species was Ceriops decandra (0.68). The area was considered to be diverse at 0.7206. On per transect basis, the highest index of diversity recorded was in Transect 2, while the lowest was in Transect 1. Avicennia and Sonneratia species occured both in the low intertidal zone (seaward) and mid-intertidal zone (transitional zone). Rhizophora, Nypa, Camptostemon, Osbornia, Lumnitzera, Bruguiera, Ceriops, Exoecaria, and Aegiceras were found in the mid-intertidal zone (transitional zone). Xylocarpus, Scyphiphora, and Acanthus occurred in high intertidal zone (landward). Avicennia rumphiana had the highest seedlings density of 1001 seedlings/ha, whereas Rhizophora mucronata had the highest saplings density of 96 saplings/ha. The lowest seedling and sapling density was Rhizophora apiculata (Iseedling/ha) and Camptostemon philippinensis (lsapling/ha) respectively. The species with the highest computed biomass of 1,287.78 tons/ha and carbon stock of 579.5 tons/ha was Sonneratia alba. The lowest was Ceriops decandra with biomass of 0.06 tons/ha and carbon stock of 0.03 tons/ha. A total of 2,080 tons/ha biomass and 936.34 tons/ha carbon stock was determined. Based on the litter fall, Transect 2 has the highest leaf fall weighing 580.4g. Litter weight was highest in January 2013 and lowest in December 2012 in all sampling sites.Item Karyotype analysis of Kutsay Allium odoratum L. (Alliales: Alliaceae)Bermejo, Jo-am Asis (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1995-05)The C-metaphase count of Allium odoratum revealed that the chromosome number was 2n=32, consisting of the following centromeric groups based on Levan's method of chromosome classification: Group I chromosomes with subterminal centromeres (1 pair); Group II with submedian centromeres (2 pairs), and Group III with median centromeres (13 pairs). The mean total lengths of chromosome ranged from 8.534±0.504-16.624±0.600 μ. Mitotic index for the species was found to be 10.87%.Item A study on the preference of the UPV Social Science student between violence and non-violence as a progress on change in the Philippine societyBerlin, Sharon Joy (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1983-04)The study was conducted among 100 students of the Division of Social Sciences, University of the Philippines in the Visayas, Iloilo City. It attempted to answer the following questions: 1. Violence and Non-violence: which would the students prefer in changing society? 2. Is their preference related to some observable factors like sex, religiousity and family income? 3. What is the attitude of students towards the present government? The respondents were almost unanimous (94%) in their belief that Philippine society needs social changes. Moreover, they perceived the monopoly of power by the few’ as the primary problem of the nation. In the question of political preferences between the different methods of social transformation a considerable number (59%) preferred the use of both violent and nonviolent conduct in effecting changes. When factors like sex, religiousity and family income, were subjected to Chi —Square test, the result is as follows: 1. Female students were not politically less violent than their male counterparts. 2. The more religious the student the less likely he is violent. 3.High family income do not necessarily produce a preference on non-violent method. As to the third question, "What is the attitude of students towards the present Government?", there was a high (91%) percentage that the present government works for the service of the few. A moderate number (52%) believed that the government can not solve the country’s problem, but in terms of the national leadership, a considerable number (61%) categorized it as fairly responsive.Item #Communitypantry: Perceived impact of online public opinion on government policy amongst college students and local government officials of Iloilo CityBernal, Xyrille Joy P.; Socias, Pearl Rylene Mae S. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2022-06)Public opinion, accommodated through public policies, is a precondition to democracy. This study aimed to determine the perceptions of college students and local government officials concerning the impact of public opinion and online activism on Iloilo City’s COVID 19 pandemic responses, specifically on community pantries. It probes how public opinion expressed through the social media trending topic of community pantries shaped local government responses. A descriptive design was employed to determine the perceptions of the college students (n=108) and local government officials (n=3). Hybrid quantitative-qualitative research approach was used thorough survey, interview data and online archives (i.e.., social media postings and news reports). Major findings include: college students perceive moderate effectiveness of public opinion in influencing government policies but depict overall low Twitter outputs; local government officials perceive public opinion as essential in governance but not as important as directives from the national government; and the city's local government officials have reservations about social media-conveyed public opinion’s direct effect on pandemic-related policies. Employing the Normative Framework of Democratic Theory that deals with the foundations of democracy, democratic institutions, and policy deliberation processes, the theory explained how respondents & key informants varied in their perception of social media as a tool for public policies.Item Navigating the redevelopment dilemma: The impact of Iloilo City central and super market rehabilitation project on ambulant vendors from rural areasBermil, Dannah Veronica M.; Magbanua, Gwyne Winnah B. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2024-06)This study examines the marginalization of ambulant vendors in Iloilo City's Super and Central markets during ongoing public-private partnership (PPP)-driven market rehabilitation projects. It explores factors influencing vendors' experiences and perceptions, focusing on the impact of PPP projects and the city government's response to their needs and participation in consultations. Employing a cross-sectional and exploratory approach, it used data from interviews from ambulant vendors and key informants and utilized purposive sampling and thematic analysis. Findings point to challenges encountered during redevelopment, such as sales decline and exclusion from decision-making processes. Ambulant vendors respond by diversifying products, yet they confront negative perceptions and insufficient support. Recommendations include advocating for fair operating conditions and city government assistance to ensure sustainable livelihoods. Drawing upon Urban Politics Theory and Resource Dependency Theory, the study underscores systematic marginalization and emphasizes the necessity of inclusive decision-making mechanisms to empower ambulant vendors within urban governance structures. Recognizing their agency and advocating for their rights can catalyze equitable urban development, benefiting all stakeholders. This research offers valuable insights into the intricate dynamics of urban development and the marginalized role of ambulant vendors, urging policymakers to prioritize their inclusion in future planning initiatives.Item 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 Comparative analysis of the program format of TV Patrol and 24 OrasBerja, Alice Bernadette F.; Nidoy, Michelle Gay M. (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)This descriptive-comparative study aims to determine the program format of the two mainstream TV news programs here in the Philippines: TV Patrol (ABSCBN) and 24 Oras (GMA). There are two types of TV news program format, standard format and tabloid format. Both formats are guided by four elements: segment, news selection, news delivery and language. Survey was used in measuring the knowledge of Ilonggo viewers on the program format of TV Patrol and 24 Oras. The study covered 12 barangays in Iloilo City with 400 respondents. Results of the data-gathering process showed that TV Patrol is in tabloid format while 24 Oras is in standard format. News delivery is the most tabloid element of TV Patrol while Language is the most standard element of 24 Oras. Both formats have implications to the viewers’ knowledge and perception towards the reality of news stories.Item The political elites of Tubungan, Iloilo: Their characteristics and contributions to the municipality, 1992-2001Beriones, Beben C.; Garbe, Adeste B. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2001-03)This is a descriptive study on the characteristics and contributions of the political elites of Tubungan, Iloilo to their Municipality from 1992 to 2001. It is focused on the mayors, the vice-mayors and the members of the Sangguniang Bayan. The researchers presented the characteristics and the contributions they have made for the development of their municipality. The political elites’ contributions were measured in terms of the programs, the projects and the ordinances they have made. There are three factors that helped the researchers in the discussion of the topic: (1) The political careers of the political elites, (2) the characteristics of the political elites, and (3) their contributions to the municipality of Tubungan, Iloilo. In as much as ideal and necessary, the researchers tried to gather all documents about the topic, and tried to interview all the political elites; however, it was not possible due to some constraints like some documents were already lost, and two of the political elites are already living outside the province. The findings of the study is that the political elites of Tubungan share some common characteristics such as: (1) all have landholdings, (2) all are active members of organizations in their municipality, (3) all are earning more than Pl00, 000 a year, (4) all are Roman Catholics, & (5) all are contributing to their municipality’s development. The mayors’ contributions are viewed in terms of projects and programs such as infrastructures, delivery of social services and improved agricultural productions. For the vice-mayors and the Sangguniang Bayan members, their contributions are measured in terms of the number of ordinances that they have legislated aimed at improving the lives of the people of Tubungan. Finally, the people of Tubungan viewed their contributions to be beneficial.
