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 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 Agrarian reform implementation in Barangay Indag-an, Miag-ao, IloiloBeñosa, Zoraida P. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1996-03)Agrarian Reform is a program set by the government to correct socio-economic imbalances by distributing lands to the farmers who are landless It is a means of uplifting the farmers from social inequalities and the bondage of poverty. Given the nature of the program, it is therefore important to assess the effectiveness of Agrarian Reform Implementation in the community level. Specifically, this is a study of Agrarian Reform Implementation in barangay Indag-an, Miag-ao, Iloilo. The objectives of the study are to describe the processes involved in the implementation of Agrarian Reform in Indag-an, to identify the benefits and support services extended by the program to its beneficiaries, to assess the effectiveness particularly the strengths and weaknesses of the program as perceived by its beneficiaries, to describe the relative effects on male and female household members and lastly, to draw implications on how to improve the Agrarian Reform implementation in the community level. Given these objectives, data were gathered from 35 respondents through a focus group discussion method. Personal interview and a case study were also done to assess the effectiveness of the program. The findings revealed that some beneficiaries believed that they benefitted from the program. Others, however, were a bit cynical towards its implementation. They claimed that the program was biased in Its implementation wherein it caters to the demands of the landlords disregarding the needs and problems of the farmers concerning the distribution of lands. The study further revealed that the support services extended by the program to farmer-beneficiaries centered mainly on agricultural extension, agricultural credit, education and trainings, cooperatives and legal services. Other support services such as infrastructures, health assistance, potable water supply and irrigation system were not provided by the program. As to the strengths and weaknesses of the program, it has been found out that the farmers repressed an ambivalent view about its implementation. They perceived the program as both having strengths and weaknesses wherein the former focused mainly on the processes involved in the distribution of lands while the latter focused more on the insufficient support services provided by the program. Finally, the study revealed that majority of the beneficiaries was male and women beneficiaries comprise only a small number. The male beneficiaries dominated the farm works, relegating women to household chores and aspects of farm work such as planting, weeding, preparing and bringing the food to the fields. However, women were given the opportunity as men in giving opinions, airing their views in the organization. Generally, both had gained from the program, where each has his/her role in farm production, even though the extent of their benefits variesItem Gender analysis on the modes and extent of participation in Community-based Fishery Resource Management (CFRM) project in Malalison island, Culasi, AntiqueBenliro, Patriana Z P.; Eraste, Concepcion E. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2003-03)A Gender Analysis on the Modes and Extent of Community Participation on CFRM in Malalison Island, Culasi, Antique was conducted in June 2002-Feruary 3003. The study aimed to determine the modes and extent of participation in Community- based Coastal Resource Management through the Community-based Fishery Resource Management (CFRM) Project using Program Monitoring with interview and focused group discussion. The difference on the modes and extent of participation of sex and membership in the association was also assessed. The study found out that male and female modes of participation in CFRM had no significant difference. The difference was in the extent of their participation, which was caused by the social roles they played. On the other hand membership in the organization was found to be a significant variable in analysing the modes and extent of participation.Item A survey study on the motivations, gender roles and gender perspectives of elected women officials in Iloilo Province from 1988-1992Belloga, NC C. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1995-12-12)One hundred elected Iloggas from 28 municipalities of Iloilo Province were interviewed to define their demographic profile, motivations in joining the electoral politics, gender roles, and perspectives based on selected sociopolitical gender issues. This study revealed that most of the respondents are married, aged 40 to 74, have an average of 4- 5 children. Majority of them acquired secondary education, and only 28% are degree holders with female gender courses such as BS Nursing, BS Education, and BS Commerce. Most of these women entered politics in 1988, and most of them came from political clans in their municipalities. All of them joined civic or religious organizations in their municipality. Majority of the respondents supported or initiated government projects during their term of office in the areas of beautification, sanitation, health, and environment arid mostly are geared towards the upliftment of the standard of living in their areas. This study established that most of the respondents performed traditionally female gender roles such as housekeepers, wives and mothers. They also assumed male gender roles such as elected public servant and farmer. Only a few performed non-gender roles such as being a student and engaged in business. Majority of them assumed a triple role? by simultaneously fulfilling their domestic reproduction, production and community management obligations. Majority of these women officials were initially motivated to join politics by their desire to serve the people. Most of them are hesitant to join because they lack political knowledge and public service experience. However, despite of their hesitations, these women decided to run for public office because of the assured support given by their family and friends. Majority of these women did not perceive that their being women marginalizes them in politics. Instead, they view such factor victory which proved that constituents preferred them over leading to their male candidates. Most of these women did not perceive that politics is a man's world with reference to the success of Cory Aquino and Miriam Santiago as female politicians. Majority of then? qualified their opinion on woman's exclusive dominion of home, arguing that women cam only go beyond their household duties if they know they are capable to perform public functions. They define their gender role in Philippine society as helpers, assistants and character molders of the youth. Majority of these women also qualified their opinion on the equality of men and women, asserting that in terms of physical capabilities men are more superior and in areas such as home management arid child tearing. Majority of these women did not perceive that Filipino society is a male-biased society. They view women as capable of occupying national political positions ar?d bias numeric advantage over men. However, majority agreed that Filipino women occupy subordinate roles to men in society because women are weak, less aggressive, receive insufficient support, and have scarce opportunities. Most of the respondents find politics difficult, especially in settling disputes. They contend that once they gained the? respect, of their constituents, they feel competent to tackle the tasks. It is evident that women politicians still adhere to the patriarchal belief and have unresolved gender definition, which are contributory factors to the discrimination of women in politics.Item Cost and return analysis of milkfish operations in different farm sizes in Barotac Nuevo, IloiloBelgira, Gay Nanette (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1996-07)Milkfish (Chanos chanos) is the most important pond cultured fish specie in the Philippines. Barotac Nuevo, where the study was conducted, is among the most productive in the province of Iloilo in terms of milkfish culture. Cost and Return Analysis of Milkfish Production evaluates the economic performance of 30 milkfish farms in Barotac Nuevo, Iloilo. The economic performance of milkfish farms were assessed using profit, revenue, return on investment, rate of return on operating cost, and payback period. Investment and cost structure were also presented. Comparative analysis was done by farm size namely; small farms (less than 5ha), medium farms (5.01 to 20ha) and large farms (above 20ha). Farm investment increased as farm size increased. The highest yield per hectare per crop was obtained by medium farms (708.86kg) followed by large farms (566.76kg) and small farms (394.16kg). For all farms, economic profit decreased as fann size increased on a per farm basis. Small farms had an economic profit of P7,525.25. Medium farms had P55,157.66 while large farms had P131,575.59. Results showed that variable cost of medium farms(21,056.97) on a per hectare basis was higher than that of the large farms(20,298.67) while fixed cost of all farms on a per hectare basis decreased as farms size increased. Opportunity cost of farms on a per hectare basis decreased as farm size increased. Small farms had the lowest return on investment (14.30%) followed by medium farms (30.68%) and large farms (42.31%). Rate of return on operating cost for small farms was 56.03% while medium farms had 26.53% and large farms had 13.14%. Payback period of all farms decreased as farms size increased. Small farms had 6.99 years, medium farms had 3.29 years and large farms had 2.36 years. From all economic indicators presented, milkfish pond culture remains a profitable business venture in Barotac Nuevo, Iloilo. Small farms were found to be productive due to the close farm supervision devoted by owners themselves, but medium farms were found to be most profitable farm size to operate in milkfish pond culture in Barotac Nuevo, Iloilo. Large farms has lower yield because of the large area it occupies that an operator can hardly check all areas.Item Social responsibility on the use of media technologyBeloya, Marian Kristina C.; Camancho, Rea Micah C.; Perez, Mary Lydannie V.; Villanueva, Ma. Emilie M. (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 2005-10-21)This study is about responsibility on the use of media technology specifically cellular phones. The study is done through a survey measuring on respondents’ behavior and awareness of social responsibility pertaining to the use of cellular phone. Residents of UPV Miagao dormitories (Balay Apitong, Balay Gumamela, Balay Lampirong, Balay Kanlaon, and Balay Madyaas) were chosen as respondents to the study. The results of the study show that the respondents are Aware of their social responsibility but they are Sometimes responsible in using their cellular phone and as senders and receivers. Therefore, the UPV Miagao dormitory residents are Quite Socially Responsible on the use of media technology specifically cellular phones.Item Histomorphological study of the gonads of Pholas orientalisBeluso, Michelle O. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1994-04)A total of five "diwal", Pholas orientalis, two of which wore obtained from Hinigaran, Neg. Occ. on January 1995 and three from Lanas, Barotac Nuevo on February 1994, were examined for the histomorphological study of the gonads of the species. Among the five samples, two were males and three were females. No hermaphrodites were encountered. Macroscopical examination showed that the gonads were diffused in the visceral mass extending from the anterior to the posterior part of the animal. The gonads were arborescent in form and creamy in color. No external sexual differences were observed. Histological examination showed that male and female gonads were scattered in the visceral mass and concentrate most around the stomach. Male and female gonads consist of follicles which were lobular and embedded in the connective tissues. Three sexual maturity stages were observed among the five specimens, which are the late active, ripe, and partially spent stages. During the late active stages in both male arid female gonads, developing gametes (spermatocytes and young oocytes, respectively) are attached to the follicular wall with maturing gametes lying free in the follicular lumen. At the ripe stage, male gonads showed mature sperms free in the follicle lumen with sperm tails radiating into the center of the lumen. In females, ripe oocytes are free in the follicle lumen with some maturing oocytes still attached to the folli- cular wall by a slender stalk. Partially spent stage was observed only in females. Spent gonads showed spaces in ovarian follicles due to loss of ova through spawning (1938). Since there is a growing demand for "diwal", interest on this species had picked up lately. One of the earliest studies on P. orientalis was the study on the "diwal" fishery in Neg. Occ. conducted by Ablan (1938). The larval biology and mariculture of the angelwing clam, Cyrtopleura cos- tata, were studied by Gustafson, et al. (1991) and investigations into spawning and hatchery technique for P. orientalis are underway (Gustafson, et al., 1991). Studies on the biology of P. orientalis are few and in fact no literature regarding reproductive biology of the species was obtained. Thus, this study was carried out with the following objectives: (1) to determine the location of the gonads in the visceral mass of P. orientalis, (2) to describe the histomorphology of the gonads, and (3) to differentiate the gonadal conditions histologicallyItem Community structure of riverine mangrove stand in Brgy. Talokgangan, Municipality of Banate, Iloilo ProvinceBelaño, Keith Dominador L. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2001-04)The community structure of riverine mangrove stand in Brgy. Talokgangan, Municipality of Banate, Iloilo was studied. Ten “true” mangrove species representing seven families were encountered in the “mangals” of Balandra creek community in Brgy. Talokgangan. They were Avicennia marina, Avicennia lanata and Avicennia alba representing Family Avicenniaceae; Rhizophora apiculata and Rhizophora mucronata under Family Rhizophoraceae; Sonneratia alba of the Family Sonneratiaceae; Excoecaria agallocha under Family Euphorbiaceae; Camptostemon philippinense of the Family Bombacaceae; one from the Family Meliaceae namely Xylocarpus granatum, and Family Palmae represented by Nypa fruticans. Stand Basal Area was computed highest in Station 1 with 10.22 m2/ha. Station 1 was also the densest among the four stations with a density value of 2533 trees/ha. In terms of data evaluated per zone, the landward zone has a Stand Basal Area of 10.87 m2/ha which is slightly higher than the middle and riverward zones. The middle zone, however, was found to be the densest with 1850 trees/ha. The most dominant station was Station 1 with the highest Index of Dominance of 0.3319, however, was found to be the least diverse station. The highest Index of Diversity was computed in Stations 2 and 3, with diversity indices of 0.8976 and 0.8989 respectively. Avicennia marina was found common in all stations and the most dominant, making it the most important mangrove species. They were found to occupy the whole site, growing abundantly in wide range of conditions from areas frequently inundated by tidal flow in Station 1 to the firmer muddy substratum in the back mangrove areas. Rhizophora apiculata and Rhizophora mucronata was observed to occupy waterlogged soil conditions. Excoecaria agaliocha tend to flourish in firmer muddy substratum in open sites, whereas, Xylocarpus granatum was observed to occupy zones where salinity is lowest in areas rarely affected by tidal flow. Sonneratia alba and Camptostemon philippinense tend to grow in zones directly inundated by tidal flow.
