The effects of the Gawad Kalinga Resettlement program to the general self-efficacy, task orientation and functional social contacts of the schooled adolescents in Gawad Kalinga Villages in Iloilo City
Caminos, Ann Marie P.; Deveza, Ma. Catalina G. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2010-03)
There had been a lot of studies conducted about the Gawad Kalinga (GK) adult residents. This descriptive study will venture on the schooled adolescents (13-19 yrs. old) in the two (2) GK sites, the Sooc, Manduriao Village and the Buntatala, Jaro Village, specifically about their General Self-Efficacy(GSE), Task-orientation and Functional Social Contacts (FSC). General Self-efficacy Test by Schwarzer (2009) and FGD questionnaires are the materials used in this study. There were 47 schooled adolescents. Each GK site was divided into 2 groups (highest and lowest GSE) with 5 participants for each FGD session. It is found that GK program helped the respondents in terms of their adaptation in their new environment. However, the program does not affect their task-orientation because it is mainly influenced by their families. The program does not also serve as a direct functional social contact because of the type of social network they seek in times of problem.
Anti-inflammatory activity study and vitamin C analysis of fruit wine from "BIKA" Vitis quadrangularis wall (Vitaceae)
Camillon, Imee Ruth B. (Division of Physical Sciences and Mathematics, College of Arts and Sciences, University of the Philippines Visayas, 2003-05)
"Bika" Vitis quadrangularis Wall fruits are non-toxic raw material for wine making. Cytotoxicity test using the Brine Shrimp Assay showed that the crude ethanolic extract has an LC50 higher than 1000 pg/mL.
Using the Standard Iodine Method, "bika" fruit was found to contain 789 ppm vitamin C however, analysis of the "bika" wine showed a lower amount (10.8-29.1 ppm vitamin C) .
Using the Carrageenan-Induced Edema Assay, "bika" fruit was observed to have a notable anti-inflammatory activity. The crude ethanolic extract and the positive control showed a 75.0% and 38.5% inhibitions respectively, with the latter at a lower concentration than the extract. "Bika" wine's anti-inflammatory activity was slightly lower than the fruit. The wine showed a percentage inhibition of 30.2-56.6%.
The first five days of the fermentation was the peak of the yeast activity as indicated by a significant change in the specific gravity, pH and total acidity of the must.
Extraction, partial, isolation and detection of borapetoside A from the leaves of Tinospora crispa (L.) Hook. f. & Thomson (Makabuhay)
Camelote, Rammela Ann B. (Department of Chemistry, College of Arts and Sciences, University of the Philippines Visayas, 2018-06)
Borapetoside A was extracted from the leaves of Tinospora crispa by a series of liquid-liquid extraction using solvents of different polarities (chloroform, CHCl3; ethyl acetate, EtOAc; n-butanol, n-BuOH). The n-BuOH extract was concentrated and partially purified by column chromatography using solvents of increasing polarity (100% dichloromethane (DCM), 1:1 DCM-EtOAc, 100% EtOAc) to yield Al, A2 and A3 fractions, respectively. TLC profiles of each fractions revealed that A2 fraction has the most distinct and relatively well-separated spots among the other fractions. For this reason, A2 was subjected for targeted detection of borapetoside A using LC-MS. Results revealed the presence of LC peak at m/z 537.3380 Da that eluted at approximately 2.59 min. Based on several published literatures on T. crispa (Bisset and Nwaiwu, 1983; Fukuda et al., 1983, 1985, 1986; Pathak et al.,1995; Martin et al., 1996; Cavin et al., 1998; Kongkathip et al., 2002; Choudhary et al., 2010), there is no known compound in T. crispa that corresponds to this m/z value. The closest molecule that we can come up with, given the LC result in this study, is borapetoside A having an exact molecular ion mass of 538.2050 Da. The mass difference of 1 Da maybe brought about by a loss of a neutral H atom which was previously observed in samples subjected to ESI (Ramalho et al., 1997; He et al., 2013; Guo et al., 2014). Results therefore suggest that the method for partial extraction, isolation and detection of borapetoside A in the leaves of T. crispa outlined in this study is successfill. The method, however, must be validated by subjecting A2 into further purification by preparative HPLC and characterization of the resulting LC fractions using MS and NMR spectroscopy.
Effect of size on spawning of Imbaw, Anodontia edentula (Linnaeus, 1758)
Cambel, Marianne P. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2008-04)
The effect of shell size to spawning of imbaw, Anodontia edentula was examined. A total of 120 clams with shell length ranging from 34.90 to 68.20 mm were collected. Basing on shell length, 3 class sizes were used to group these clams, namely: < 45 mm, 45-50 mm, and > 50 mm. Thirty-five percent of the clams had shell length of < 45 mm, 21.7% in the range of 45-50 mm, and 43.3% had shell length of > 50 mm. Overall result showed that a high percentage of the clams in the range of 35 to 50 mm responded to spawning induction. Result showed that 41 (98%) of the clams in class size < 45 mm spawned. Twenty-six (100%) of the clams in 45-50 mm spawned and 31 (60%) spawned in class size > 50 mm. A mortality of 2 occurred among the broodstock and had shell lengths of > 50 mm. Among the clams induced to spawn, males predominated in the sample. Only 1 case of hermaphroditism was observed in < 45 mm and no females were observed to spawn. The only immature male in class size < 45 mm has a GSI value of 22.3. The mean GSI value of the 19 immature clams in class size > 50 mm was found to be 23.9 (±7.62).
Households' participation in community-based solid waste management program
Camayra, Zyllette G.; Casimero, Joeuella M. (Division of Social Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2007-04)
Proper management, of solid waste is the answer to the worsening problem of garbage. The participation of the household sector, as the primary source of solid waste, plays an important role in the successful implementation of Community-Based Solid Waste Management Program (CBSWMP).
The study aims to determine whether there is a relationship between households' participation in Community-Based Solid Waste Management Program and the age and awareness of the household head as well as the monthly income of the household, it seeks to accomplish the following objectives: (1) To describe the profile of the households in barangay Mat-y, Miagao, Iloilo, with active CBSWMP; (2) To determine if there is a relationship between households’ participation in CBSWMP and age of the household head; (3) To determine if there is a relationship between households' participation in CBSWMP and income of the household; (4) To determine if there is a relationship between households’ participation in CBSWMP and awareness of the household head.
The sample of the study involved residents of barangay Mat-y. Miagao, Iloilo. Eighty respondents, from the total 320 probable respondents, were randomly selected and interviewed. The interview was made possible using an interview schedule.
Statistical analysis of the data revealed that, age, monthly income and level of awareness did not show direct correlation with respondents’ participation with CBSWMP. Although, a relationship exists among variables and participation on CBSWMP, the nature of relationship is weak and inverse thereby not giving significant findings.
From the results, it can be said therefore that, the participation of households in CBSWMP may depend on households’ attitudes and behavior towards the program. The researchers recommend further research to be conducted on households’ participation in CBSWMP but using other variables not included in this study.
