    The health status of school-age children in Barangay Ingore, La Paz, Iloilo City
    Amamanglon, Keanne Paula H.; Bragancia, Ira May Joy E.; Gulmatico, Gideon M.; Guzman, Virgi Chrisbelle A.; Mercado, Pauline Victoria M.; Orbase, Jannina Faye O.; Reyes, Mary Camille E.; Yap, Maria Lorna Christy C. March (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2011-03)
    The study is a cross sectional survey to assess the health status of school-age children in barangay Ingore, La Paz, Iloilo City. The health status of the children was evaluated using nutritional status assessment, child care practices of mothers/caretakers and past and present clinical history of disease, and respiratory function. Anthropometry and Clinical Signs were used to directly assess the nutritional status of the children. An Interview Schedule, with mothers/caretakers as respondents was used to determine the socio-demographic characteristics of the household to where the children belong and also to obtain information on their child health care practices. Respiratory or Lung Function was assessed using Lung Peak Flow and Chest Expansion. The results of Anthropometry using the parameters for Weight-for-Age (WFA), Weight-for-Height (WFH) and Height-for-Age (HFA) revealed that 16.3% of the school-aged children were underweight; 10.7% were thin or wasted; 24.4% were stunted, and 4.0% were overweight/obese. The most common clinical signs indicative of malnutrition were pale conjunctiva and the occurrence of dental carries. Most of the children have been breastfed and availed of complete immunization during their pre-school age period. Almost half of them experienced childhood diseases like upper respiratory tract infections (e.g. cough, common colds, asthma, etc.). Peak flow analysis showed that among male, school-age children the average peak flow was 210.6L/minute while among female it was 195.7 L/minute. The computed average peak flow was 203.2 L/minute. The average chest expansion of the subjects was 2.4 cm and the chest expansion of male and female school-age children was 2.4 centimetres. The results obtained in this study can be used as a baseline for future studies especially in the light of the recent operation of a coal-fired power plant which might affect the health status of vulnerable age groups like pre-school and school-age children

    Salinity tolerance of the angelwing clam, Pholas orientalis larvae
    Aguaras, Lovie Grace P. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2011-03)
    Pholas orientalis, locally known as “diwal” is one of the commercially important bivalves in the Philippines due to its delicate and sweet taste. An experiment was conducted to determine the salinity tolerance of the 24-hour-old larvae of this clam when reared in different salinity levels of 25, 30, 35, and 40 ppt. The experiment lasted for 15 days at a rearing temperature of 25° C - 27° C. Determination of survival rates and water change were done twice every week. The data gathered were then analyzed using one-way ANOVA. Results showed that survival rates were significantly high at salinities of 30-35 ppt and were significantly low at salinity levels of 25 and 40 ppt. It was also observed that there was an increasing trend of mortality with prolonged exposure to different salinity levels. This could be attributed to the limited osmoregulatory capabilities of the larvae. When reared at low salinity levels, larvae were faced with the danger of too much water entry which eventually led to death. Meanwhile, when reared at high salinity levels, the larvae died due to outward movement of water which resulted to dehydration. Information on the salinity levels that could be tolerated by diwal larvae will be an important factor in the development of larval rearing techniques for successful hatchery operations. The juveniles or seeds produced in the hatchery could be used to restock the depleted resources in the wild.

    Determination of the concentration of essential minerals (Ca, Fe, K, Mg, Na, Zn) in honey samples from Negros Occidental
    Arellano, Lory Mae F. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2018-06)
    Honey is a natural, sweet and highly nutritional substance produced by bees through a series of nectar collection and chemical processes. Due to the popularity of the product, certain regions in the Philippines has been producing honey and recently, different apiaries from Negros Occidental has been producing its own share of popular product in the market. The products are well received by the consumers, but the problem is the lack of characterization which gives the product doubtful and unconfirmed nutritional value. This study focuses on the quantification of essential minerals (Ca, Fe, K, Mg, Na, Zn) present in local honey samples from Negros Occidental. Eight honey samples were obtained from the different apiaries including an external sample from Mindoro. Samples were acid digested using HNO3/H2O2 solution at 130 °C. The concentration of each minerals in the honey samples were analyzed using AAS. The data reported high concentration (5.71 to 93.20 ppm) of K on most of the samples. The second most abundant mineral in the local honey is Ca ranging from 13.67 to 45.88 ppm. The Mg concentration ranges from 1.19 to 4.09 ppm while Na is in between 0.82 to 3.14 ppm. The mineral Zn and Fe contained the lowest concentration in most of the samples with Zn at 0.46 to 0.86 ppm and Fe at 0.04 to 0.30 ppm.

    An estimation of the supply of cattle in the livestock auction market in Leon, Iloilo
    Andrada, Clyde (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 1991-05)
    This study was an economic analysis of the supply of cattle by the direct cattle producers in Leon Livestock Auction Market in Leon, Iloilo in 1989. The study includes the estimation of the supply function, the identification of the significant factors affecting the supply and the analysis of the price elasticity. The supply function of cattle were hypothesized to be affected by four (4) factors, namely: price of cattle (X1) value of inputs used in cattle production (Xz), price of related commodities (X3) and the availability of credit (X4). Simple Random Sampling was used in choosing the thirty (30) respondents who, were direct cattle producers who sold their cattle in Leon Livestock Auction Market in 1989. These cattle producers were interviewed with the use of an interview schedule. The data gathered includes total weight and number of cattle supplied in the market by the producers and the prices of resource inputs used in the cattle production. Other data such as the price of cattle per kilogram liveweight were taken from the records of the Bureau of Agricultural Statistics. Regression Analysis was applied to determine the coefficients of the supply function. Specifically, stepwise regression analysis was used. Results of the study showed that the estimated supply function of cattle was Qs = — 1843.4461 + 96.6056 X1, where x; is the average price of cattle per kilogram liveweight. Thus, the only significant factor affecting the supply of cattle was the variable X1. The price elasticity supply is 4.6984. The supply of cattle is therefore price elastic because the percentage change in cattle supplied is greater than the percentage change in price.

    Indigenous knowledge, beliefs, and practices in rice farming of people in Cuyo Island, Palawan
    Acero, Agnes B.; Prado, Edelyn A. (Division of Social Scviences, College of Arts and Sciences, University of the Philippines Visayas, 2005-03)
    This study was conducted to determine the indigenous knowledge, beliefs, and practices in rice farming of people in Cuyo Island, Palawan. It also aims to find out the indigenous knowledge, beliefs and practices in planting, harvesting, storing, processing, and selling rice products. Both primary and secondary data are used in this study. Data collection was done using interview schedule. Two sets of respondents were interviewed to collect data - the farmers and some key informants such as the barangay captains, and the oldest people of the two (2) barangays. The study was conducted in the barangays of the Municipality of Magsaysay, Cuyo Island, Palawan. These barangays are Igabas, Emilod, and Balaguen. Data were analyzed using descriptive statistics. Results of the study show that Cuyunon farmers have many existing traditional practices related to planting, harvesting, storing, processing, and selling rice products. It also shows that Cuyunons practice traditional farming in the same way that upland rice farmers in some parts of the Philippines do. Based on the results the researchers recommend that the following aspects about the Cuyunon farmers should also be studied: (1) existing development programs implemented by the Government Agencies, and NGOs related to rice farming in the locality; (2) assessments of farmers attitude towards these programs; (3) accessibility of the technology introduced by these agencies; and (4) feasibility of establishment of a people’s organization among the farmers.
