    A correlational study on the self-evaluation of job performance and job satisfaction among CAS-UPV teachers
    Cabardo, Liberty Rose A. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1997-04)
    The purpose of this study was to determine the job performance and job satisfaction of CAS-UPV teachers, and to examine the relationship between performance and satisfaction. Specifically, three elements were included in this study: (1) the self-evaluation of job performance among CAS-UPV teachers by division, educational attainment and years of teaching experience; (2) the self-reported job satisfaction among CAS- UPV teachers; and (3) the relationship between job performance and job satisfaction. A non-experimental correlation research design was used in this study. The population of the study consisted of all College of Arts and Sciences (CAS) teachers of the University of the Philippines in the Visayas (UPV), Miagao campus, Iloilo. Out of the 107 possible respondents, 74 respondents returned their questionnaire which had three parts: the PERSONAL INVENTORY PROFILE, the SELFEVALUATION QUESTIONNAIRE ON JOB PERFORMANCE, and the JOB SATISFACTION SCALE. Using the one-way ANOVA, it was found that: (1) there was no significant difference in the self-evaluation of job performance when the CAS-UPV teachers were grouped according to division and educational attainment; (2) there was no significant difference in job satisfaction when the CAS-UPV teachers were grouped according to their respective division; (3) there was a significant difference in the self-evaluation of job performance when the CAS-UPV teachers were grouped according to years of teaching experience; (4) there was a significant difference on job satisfaction when the CAS-UPV teachers were grouped according to educational attainment and years of teaching experience; and (5) there was a significant relationship between job performance and job satisfaction.

    The pharmacological screening of Moringa oleifera Lam.
    Burgos, Karen J. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1998-07)
    Moringa oleifera, Lam, or malunggay, belongs to Family Moringaceae. The medicinal value of this plant has long been recognized in folk medicine. Not all the claims, however, are proven scientifically. This study aimed to (1) test the crude extracts from the seeds and leaves of M. oleifera for pharmacological properties and (2) to compare its efficacy with the drugs commonly used to alleviate particular ailment. Phytochemical assay for alkaloid using Culvenor-Fitzgerald method was done to test the presence of alkaloids. The dried seeds and young leaves were extracted with methanol and concentrated under reduced pressure at 45°C. The resulting extracts were partitioned and used for the different assays: Brine shrimp assay for cytotoxicity, Acetic acid-induced writhing assay for analgesic activity, Charcoal tracing assay for antispasmodic activity and paper disc diffusion method for antimicrobial activity. Result showed that only the seeds have alkaloids. Toxicity test revealed that the seeds are practically non-toxic but the leaves were toxic with an LC50 of 550 μg/mL after 24 hours of exposure. Of the two extracts, only the leaves exhibited analgesic activity although not as effective as Mefenamic Acid in reducing pain. The leaf extract, was also found active against Bacillus subtilis, Staphylococcus aureus , Escherichia coli,and Pseudomonas aeruginosa. The seed extract was active only against B. subtilis. Both extracts, however, are not as effective as the antibiotic drug, Amoxicillin. Results also showed that both extracts do not have antispasmodic activity. The study confirmed the antimicrobial and analgesic activities for the use of the leaves of this plant in folk medicine.

    TV exposure and study habits of UPV high school students
    Brasileño, Hazel Alice P. (Division of Humanities, College of Arts and Sciences, University of the Philippines Visayas, 1987-03)
    This study was conducted to find out the level of television exposure of high school students, to know their study habits, and to find out the relationship between TV exposure and the study habits of UPV high school students. A study was conducted among VP Visayas High School students, where a total of 137 respondents from first, second, third, and fourth year levels provided the major data of the study. A three-page questionnaire was the instrument used in gathering data. It included: respondent’s level of exposure to TV and the student’s study habits. The least part related TV exposure with study habits. Findings revealed that there is 99% television viewer- ship which means that there is a high level of TV exposure among respondents. Number of hours of viewing ranges from 30 minutes to a maximum of six hours. Most of the programs watched were foreign canned shows and were entertainment in nature. Preferred viewing schedule of most students is 7-9 p.m. Findings also showed that most (54%) of the parents imposed restrictions on their children’s viewing, particularly on the number of hours students watched TV. On the other hand, ninety-six percent (96%) of the students studied their lessons. For those who studied majority do 30 everyday for a minimum of 30 minutes and a maximum of three hours. Students preferred to study between 8-10 p.m. Students study mainly to attain high grades. In relating TV exposure and study habits results showed that TV viewing consumes most of the free time of students and that time slotted for study is utilized for viewing the medium. However, TV viewing is also helpful to the students in that it gives them information and ideas which they applied to their lessons. The chi-square test for independence was used to find out if there is a relationship between the two variables TV exposure and study habits. Results showed that there is a relationship between TV exposure and study habits, that is, the more exposed the students are to TV, the greater is the probability that the number of time spent for studying will be lessened.

    Development of probiotics determination of LD50 of previously isolated indigenous vibriolytic bacteria, Pseudomonas aerugginosa JP4, to Penaeus monodon postlarvae
    Billena, Ma. Thesa M. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2000-06)
    Previous studies showed that Pseudomonas aeruginosa JP4 is effective in eliminating pathogenic Vibrio spp. on shrimp. However, virulence studies on this strain are lacking. Hence, this study was conducted to test the pathogenicity of P. aeruginosa JP4, using different bacterial densities of 105, 106, 107, 108, 109 and 1010 CFU/ml. These were introduced to Penaeus monodon postlarvae 13 (PL13)and early juvenile (PL25) stages. After 3 days of monitoring, mortality rates and LD50 values were determined using Reed-Muench method. Results showed that shrimps can not tolerate higher bacterial densities with LD50 of 1.15 x 107 CFU/ml and 1.12 x 108 CFU/ml for PL13 and PL25 respectively. The relatively high LD50 values on shrimp stages PL13 and PL25 indicate a low virulence of the bacterial strain. Hence, P. aeruginosa JP4 maybe used as potential vibriolytic bacteria.

    Comparison of direct microscopy and concentration techniques using household bleach for the detection of acid-fast bacilli in sputum
    Bernabe, 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.

    A comparative study of the microorganisms found in the vaginal flora of pill and non pill user by Pap smear
    Bayate, 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.

    Marketing of milkfish fry in Pandan, Antique
    Bayaras, 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.

    The relationship between selected social factors and adolescent pregnancy in Iloilo City
    Bautista, Joseph Raymund I.; Funclara, Melinda Tordesillas (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2004-03)
    This study attempts to ascertain if there is a relationship between selected social factors and adolescent pregnancy. Specifically, it aims to find out if school engagement, parental supervision, foster and kinship care, religiosity, contraceptive knowledge, and mass media exposure is related to adolescent pregnancy. The researchers hypothesized that there is a relationship between these selected factors and adolescent pregnancy. Adolescent mothers between 14 to 21 years old and were either pregnant or had given birth before December 2003 from three barangays in Iloilo City were interviewed. The gathered data were then subjected to Yates corrected chi-square test of independence to find out if there is any relationship between the dependent and independent variables. It was found out that school engagement, parental supervision, level of religiosity, exposure to mass media, and knowledge in contraceptive use have no relationship with adolescent pregnancy. On the other hand, foster and kinship care was found to have a relationship with adolescent pregnancy. For future research directions, the researchers recommend to those who are interested in adolescent pregnancy to explore the interrelationship between the factors that contribute to adolescent pregnancy. The researchers further suggest that other factors, such as economic status, be explored. Increasing the number of respondents might also be helpful. Finally, the possibility that staying away from compromising situations with the opposite sex is an effective factor to prevent adolescent pregnancy could be an interesting topic.

    Decision making in the practice of birth control in a rural community
    Barrios, 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.
