    Family characteristics related to malnutrition among preschool children
    Cajilo, Ma. Donna C. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2000-03)
    This is a co-relational study of family characteristics related to malnutrition among preschool children. It aimed to: 1.) find out if there is a relationship between family size and malnutrition among preschool children, 2.) find out if there is a relationship between birth spacing and malnutrition among preschool children, and 3.) find out if there is a relationship between mother’s work and malnutrition among preschool children. The study used interview guide to gather data. It utilizes materials from books, journals, and magazines. There were 30 respondents. These were the mothers of the identified 2nd and 3rd degree malnourished preschool children of Barangay Pitogo, San Joaquin, Iloilo. The researcher utilized the entire population of the mothers of the identified 2nd and 3rd degree malnourished preschool children because there were 30 only. The researcher didn’t include the mothers of the 1st degree malnourished preschool children due to fact that nutritional status of the child easily shifts to normal condition, therefore, data gathered maybe true for a short period of time and is not reliable for further study. The data was analyzed using frequency counts, percentages, and the chi-square test for independence. The study found out that: 1) there is no significant relationship between family size and malnutrition among preschool children, 2.) There is no significant relationship between birth spacing and malnutrition among preschool children, and 3.) there is no significant relationship between mother's work and malnutrition among preschool children.

    Processing of sweet potato (Ipomoea Batatas var Bnas) into flour for bread making
    Cajilig, Ma. Madeline R. (Division of Physical Sciences and Mathematics, College of Arts and Sciences, University of the Philippines Visayas, 1984-04)
    Sweet potatoes of Bnas variety were processed into flour and its chemical composition such as moisture, fat, ash, crude fiber, protein and carbohydrates content were analyzed. Sweet potato flour has approximately 12.41% protein and an average value of 76.7% carbohydrates. The sweet potato flour was used as wheat flour extender where "pan de sal” was the test bread prepared from 50%, 40% and 30% formulation of sweet potato flour and wheat flour. These three formulations were compared with the control sample made of 100% wheat flour. A straight dough method was used in the preparation of the samples. Sensory evaluation test revealed that "pan de sal” was acceptable in all levels of substitution at 5% level of significance. This would mean that 50%, 40% and 30% sweet potato flour substitution is possible. It was also found that the samples with sweet potato flour produces more yield of "pan de sal” compared to the control sample. The cost involved in the control is considerably higher than the experimental samples.

    Utilization of morphometric and meristic characteristics to identify cultured Tilapias (Oreochromis spp.)
    Caipang, Christina Joy Rossetti A. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1995-03)
    Meristic characters (DSC, DFRC, AFRO, CFBC and GRC) and morphometric characters (SL, HL, BD, CD and IOW) were utilized to identify five small-sized, with standard lengths ranging from 55- 100 mm., and five big-sized tilapia populations, with standard lengths ranging from 110-195 mm., of forty samples each. Dorsal spine count (DSC) is the least variable while the caudal fin bar count (CFBC) is the most variable meristic character in the tilapia species studied. Analysis of variance (ANOVA) showed that all meristic characters have highly significant differences (p<0.01) among the big-sized tilapias; while in the small-sized tilapias all have highly significant differences (p<0.01) except in caudal fin bar count which was not significantly different (p>0.05). Data on morphometric characters were log-transformed and the four other characters (HL, BD, CD and IOW) were divided by the standard length (SL) to eliminate the effect of size. ANOVA showed that all morphometric characters have highly significant differences (p<0.01) in the big-sized group. Likewise, in the small-sized tilapia species, all morphometric characters have highly significant differences (pU.O5). The study also confirmed that tilapia species studied are morphometrically and meristically distinct.

    Marketing of palay and rice in the Municipality of Bugasong, Antique
    Cainap, Ma. Liza A.; Vios, Gregg Louie O. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2003-03)
    This study describes the marketing practices and cost, net farm price received by the producers, gross margin received by the middlemen and the problems encountered in palay and rice marketing in the Municipality of Bugasong, Antique. Primary data were gathered from 24 palay producers who were interviewed about their last harvest and ten middlemen who were interviewed about their last week's transactions. Of the total volume sold by the producers (164,700kg), 79.67% went to the wholesaler-retailer-miller. The highest price of Php9.50kg was received by the producers from the National Food Authority (NFA), an institutional buyer. The lowest price of Php6.43/kg was received from the wholesaler-retailer-millers. The marketing costs incurred were Php3.81/kg and Php4.32/kg by the producers who sold within and outside the Municipality, respectively. The depreciation of investments accounted for the largest share of marketing costs of both the producers who sold within and outside of Bugasong. The palay producers who had sold to the NFA received the highest net farm price of Php7.38/kg. The producers who sold palay to the wholesaler- retailer-millers in Bugasong and wholesaler-retailers based outside of Bugasong received the lowest net farm price of Php4.06/kg. By market function, three types of middlemen were identified: wholesaler-retailer-miller, wholesaler-retailer and retailer. The middlemen sold a total volume of 3,603,486.67kg of palay within Bugasong and 972,250.58kg of rice within (45.44%) and outside (54.56%) of Bugasong. The wholesaler-retailers sold the highest volume (63.45%) of palay and the wholesaler-retailer-millers sold the highest volume (23.97%) of rice. The wholesaler-retailer-millers of palay received the highest average selling price of Php8.42/kg while the retailers of rice who sold outside of Bugasong received the highest selling price of Phpl6.50/kg. Among the middlemen who sold outside of Bugasong, the wholesaler-retailer-millers of palay (Phpl.Ol/kg) and wholesaler-retailers of rice (Php7.39/kg) received the highest gross margin. For those who sold within Bugasong, wholesaler-retailer-millers of rice had the highest gross margin received at Php9.10/kg. The retailers received the least gross margin at Phpl.l5/kg. Moreover, the wholesaler-retailer-millers of palay who sold outside of Bugasong and wholesaler-retailers of rice who sold within Bugasong received the highest net return of Php0.33/kg and Php8.22/kg, respectively. The low price of palay and rice was the main problem cited by the producers and the middlemen.

    A preliminary study on the average yield of crude capsaicin from common varieties of Capsicum frutescens L. at two stages (Young and mature) using three extracting solvent
    Cadornigara, Ma. Sylvia C. (Division of Physical Sciences and Mathematics, College of Arts and Sciences, University of the Philippines Visayas, 1998)
    Crude capsaicin content of the air dried and homogenized plant material of the three varieties of Capsicum frutescens L. namely cayenne, tobasco and ‘kitikot’ were determined using diethyl ether, 99.5 % ethanol and 1.0N NaOH as extracting reagents. Statistical analysis showed no significant difference on the average percent yield of crude capsaicin on the three varieties of Capsicum frutescens L. using similar extracting solvent, but a significantly higher yield of crude capsaicin was found with 99.5% ethanol and 1.0N NaOH. Through thin layer chromatography the major components of the extracts identified could probably be capsaicinoids (Rf 15-17), carotenoids (only in 99.5% ethanol, Rf 96-97), and capsanthin (Rf 27-29) using n-hexane-acetone.

    Myths and rituals among the Babaylan of Tubungan, Iloilo
    Cadiz, Fel T. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1996-03)
    This paper is an exploratory study on myths, an important, genre in folk literature, and their relation to binabaylan in Tubungan, Iloilo. Specifically it aims to identify and discuss myths found in the locale; to describe specific agricultural rituals, beliefs, and practices; to analyze the relationship between agricultural myths and rituals; and lastly, to describe and analyze the function(s) of rituals and myths in the context of binabaylan in Tubungan. The study discusses six myths namely: Apik and Manampunay, Pinihakang Daraga, the Datu and the Panaet, the seven Bacam jars and the Panaitan, the origin of rice, corn and beans and the origin of rice varieties. These myths are then analyzed to reveal their importance in the binabaylan symbolism and ideology. The study also discusses seven agricultural rituals, namely: paminhi, patubong, panaet, panudlak, tuos, tuqurabong, and panguyanq. Each ritual is discussed including their accompanying hurabaton (ritual-chant), taboos observed and food being offered. After examining the relationship between the agricultural rituals and the myths, the paper concludes that not all myths have corresponding rituals. Certain rituals have retained their mythic explanation, some have not. Myths and rituals reveal an orientation about the world and of reality. Through the recitation of myths in rituals, people? learn not only to adjust themselves within the society to which they are? born, but also to match their personal pains and conflicts to those of the? heroes narrated in these stories. In these ways, they gain guidance and, eventually, wisdom.

    Marketing of sweet pepper in Leon, Iloilo
    Cadarin, Eden C. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1998-07)
    This study describes the marketing system of sweet pepper in Leon, Iloilo. The marketing operations of sweet pepper farmers and middlemen were surveyed. A total of fifty two (52) respondents, were interviewed, forty (40) of which are farmers and twelve (12) are middlemen . The data were based on the recent harvest of the farmers and the last transaction activity of the middlemen. The respondents are from Brgy. Buga and Brgy. Mocol, the top sweet pepper producing barangays in Leon, Iloilo. The farmers received an average P 28.69 per kg of sweet pepper sold. The marketing costs incurred amounted to P 14.19 per kg, which include the pre-sale costs, expenses on tickets, permits, ”arcabala"/bills, depreciation costs on investments and other miscellaneous expenses. The net farm price received by farmers was P 15.50 per kg. The most common problems cited by the farmers in sweet pepper marketing include pests and diseases and the perishability of the product brought about by delayed market. It was recommended that for farmers to increase their production, they need to have irrigation facilities and enough financial capital so that they will not resort to borrowing . Farmers are concern more on the financial aspect of sweet pepper production. The middlemen on the other hand, received a gross margin of P 8.39 per kg. On the average, their marketing costs amounted to P4.34 per kg. The marketing margin they received was P 4.05 per kg. Findings show that the middlemen need to procure sweet pepper in bulk to cover the high marketing costs incurred. Their primary concern is in maintaining the quality of sweet pepper to avoid losses.

    A preliminary study on the freezing tolerance of milkfish (Chanos chanos, Forskal) embryos
    Buendia, Jeremiah C. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1994-03)
    Milkfish embryos of blastula and C-shaped stages were tested for cryoprotectant toxicity using DMSO and glycerol at 10%, 12% and 15% concentrations. Survival and hatching as well as the effects of freezing were observed. Glycerol was more toxic than DMSO. Freezing at 4°C resulted in the decrease of hatching, and ice crystal formation killed the embryos during the process of freezing to -80°C. C-shaped embryos had a higher survival and hatching than the blastula stage embryos in the toxicity and cold shock tests.

    Antifungal activities of alginate films incorporated with lemon grass (Cymbopogon citratus) essential oil on sliced bread
    Bronzal, Lucile A. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2018-06)
    The accumulation of non-degradable and non-recyclable waste materials leads researches to venture on biopolymer films which have been regarded as the promising green substitutes of non-biodegradable plastic materials. However, food products can be subjected to contamination by bacteria and fungi. The addition of plant derived essential oil can control microbial contamination of foods by reducing the growth rate of target microorganisms or by inactivating microorganisms by direct or indirect contact. Incorporating antimicrobial compounds into films provides a different way to improve the safety of ready-to-eat foods. In this study, the efficiency of synthesized alginate films incorporated with lemon grass essential oil (LGEO) for antifungal activity on white bread was evaluated. Two sets of film were prepared the (1) LGEO - Ethanol incorporated films and (2) LGEO — β-cyclodextrin inclusion complex films via solution casting method. Furthermore, the FTIR analysis of the generated films was also assessed to identify the functional groups present in the film that facilitates its antifungal property. Experimental results showed that LGEO enhanced the antifungal properties in the films and significantly slowed down the propagation of fungi on white sliced bread. After two weeks of storage, all bread samples packed with various film samples showed fungal growth. It was found out that citral is the main component of essential oil which contributes to the inhibition of fungal growth. The incorporation of LGEO in the film decreased the O-H peak absorbance while the inclusion complex in the film increases the O-H peak absorbance and broad O-H peaks were also obtained.

    The effect of different levels of salinity on the spanning of ablated mudcrab Scylla serrata
    Bueno, Jesse L. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1994-04)
    Four salinity treatments with salinity levels of 15 ppt, 25 ppt, 35 ppt and 45 ppt with six replicates per treatment were utilized to determine its effect on the spawning of sexually mature bilaterally ablated mud crab Scylla serrata. The crabs range in weight from 250 grams to 580 grams and carapace width from 12.5 cm. to 16.5 cm. The results of the study showed significant difference (P<0.05) in the number of days when spawning occurred. The shortest duration when spawning occurred was at 25 ppt salinity with a mean value of 9.5 days. This was followed by 35 ppt and 15 ppt salinities with mean values of 15.69 days and 19.83 days respectively. Highest number of days when spawning occurred was at 45 ppt salinity at 24 days. All crabs died 2-3 days after spawning.
