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 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 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 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 The effect of seaweed (Kappaphycus alvarezii) as a partial substitute for commercial feed on the growth of chickenBedia, Alma Mae S. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1994-08)The study determined whether the use of seaweed (Kappaphycus aIvarezii) in different amounts as a partial substitute to commercial feeds would enhance the growth of chickens, reduce feed consumption, increase feed efficiency, and increase profit. The chickens were first fed with commercial broiler starter mash feeds for 15 days. Then, on the 16th day to the 35th day, the chickens were fed with different combinations in 1:1, 1:2, and 1:3 ratios of commercial broiler finisher feeds to K. alvarezii. Chickens fed with purely commercial broiler finisher feeds served as the control. Feed consumption, liveweight gain, and feed efficiency were computed every three days, while Profitability was determined at the end of the experimental period. Results showed that the use of K. alvarezii as a partial substitute to commercial broiler finisher feeds in a 1: 1 ratio increased the profit as well as the growth of the chickens, and it is comparable to that in the control (fed with purely commercial broiler finisher feeds). When the amount of K. alvarezii in the feed ration is more than 50% (1:1 ratio), it was observed that it would hamper the growth of the broilers.Item A comparative study of the microorganisms found in the vaginal flora of pill and non pill user by Pap smearBayate, Aimee Sarena L. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1994-03)This study was conducted to identify and classify the organisms that are present in pill users and non-pill users. It will determine if taking of pills cause changes in the microflora of pill (combined) users and will describe the profile of both pill and non-pill users. The study use 200 prepared smears of the vagina, divided equally to both pill and non-pill users. The slides were collected at Dr. Ricardo Y. Ladrido Memorial Hospital, Lambunao, Iloilo by the family planning physician with the help of the medical technologist. The profile of the patients were also gathered to provide more information about the subjects. The organisms were identified according to their basic morphological characteristic. The results indicate that bacilli which is the normal inhabitant of the vagina is present in 200 samples. Cocci is present in both groups but occure more in women who are pill users. In the parasite group, Trichomonas vaginalis is present in women who are pill user and Candida is present in both groups but occur more in women who are pill users. The test for the estimation of the difference between two proportions reveal that the z values obtained from the experiment falls between the critical region which has a value of 2.58. Such a value indicate that the prevalence of parasites and bacteria are equal among pill and non-pill users.Item The agricultural education outreach project in Aklan: Barangay Sibalew, BangaBautista, Reynold R. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1992-07)This study uses the concept of agricultural extension as a catalyst of change for rural development. Suffice it to say, the objective of agricultural extension is to provide the rural people the appropriate information, technology and values to make them self-reliant in the context of their own environment. However, the realisation of this goal is dependent on the extent of acceptance and participation of the rural people themselves. In this study, the Aklan Agricultural College-Agricultural Education Outreach Project in Aklan is supposed to bring self- reliance among the farmers of barangay Sibalew, Bangs by effective transfer of appropriate technology. Based on the principles of extension service, it has been determined that the A.E.0.p project in Sibalew, particularly its economic and social services, has been instrumental in improving the productivity and income and broadly, the social and economic aspects or the farmers life. Needless to say, the A.E.0.P-introduced technologies have been embraced by the majority of farmers in the barangay--which exemplifies the effectiveness of the A.E.O.P project.Item Marketing of milkfish fry in Pandan, AntiqueBayaras, Dinah A. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1995-03)This study describes and analyses the marketing, channels, functions/practices, costs, margins, and shares received by each marketing channel, net price of milk-fish fry received by fry catchers, and the problems encountered in the marketing of milkfish fry in Pandan, Antique. Using a separate interview schedule for each kind of respondent, 40 fry catchers are asked about their latest catch on a per-day basis, and the ten middlemen were interviewed about their last transaction/s. Results showed that from the fry catchers, the 4,218 milkfish fry are sold to three types of middlemen: the commissionman, wholesaler and facilitative organization. Fifty-nine percent of the milkfish fry go to the facilitative organisation, twenty-three percent to the commissionman, and eighteen percent to the wholesaler. From the three types of middlemen, only 86 7, of what they’ve purchased were sold of the 3,610 milkfish fry sold, 55% of it go to the wholesaler/retailer. Others go outside of the municipality. All of the wholesaler/retailer purchases go outside of the municipality. The pre-sale practices performed by the fry catchers include gathering, counting, sorting, storing, and transporting, while the middlemen perform counting, sorting, storing, packaging, and transporting. In performing the five pre-sale practices by the fry catchers, the cost of P16.95 is incurred. These are all noncash costs. The cost of P4.0012 for the depreciation cost of marketing investment items and the mortality cost of P12.95 - This includes the allowance for mortality given to the buyer as well as the actual deaths of milkfish fry - are the composition of the marketing costs. The net. The price of milkfish fry is P0.24/piece. But 23% of the opportunity cost of labor was forgone. The pre-sale practices performed by each type of middleman involved in the marketing of milkfish fry accumulated a distinct cost for each type. For the commissionman, he has a total of P87,3367 marketing cost. The wholesaler incurred — 117.996, the facilitative organization has P570.4867, and the wholesaler/retailer has Pl,365.7987. The middleman who has the highest net return in terms of percentage of average revenue is the commissionman (70.62%), followed by the wholesaler (69.76%), then the facilitative organization (57.89%), and the smallest is received by the wholesaler/retailer (37.54). followed by the facilitative middleman (P0.21), and then the In terms of gross margin received by each type of middleman, the highest shareholder is the wholesaler /retailer (P0.28), then the wholesaler (PC, 23), and the commissionman (P0.06). The problems of poor transportation facilities, insufficient capital, communications in pricing, excessive mortality rates, and the absence of a buyer are the bottlenecks in the marketing system. These problems produce a bad outcome for the middlemen by increasing their losses.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.
