Online Community of Student Organizations
No full textIn the University of the Philippines Manila (UPM), a student organization is de- fined as a group of at least fifteen students that share common goals and interests, meet regularly and work together to achieve their common goals and to form close relationships. They are classified into two: university-based and college-based. University-based student organizations are supervised by the Office of Student Affairs (OSA) Coordinator while college-based ones are supervised by the Office of Student Services (OSS) Coordinators. The Online Community of Student Or- ganizations (OCSO) provides tools that can help accredited student organizations in their organizational activities. In OCSO, each student organization is managed by administrators who are organization members assigned by either the OSA Co- ordinator (if university-based) or OSS Coordinator (if college-based). OCSO al- lows these student organization administrators to activate/deactivate organization members, create public and exclusive posts, polls, collaboration threads, activity planner and events where they can invite users. The OCSO also allows the OSA and OSS Coordinators to create announcements or posts related to students or student organizations and to review and approve first public posts made by student organizations before they will be displayed
Lead bioaccumulation in Nassarius sp., Perna viridis, and Crassostrea iredalei found in LPPCHEA.
No full textThe Las Piñas-Parañaque Critical Habitat and Ecotourism Area (LPPCHEA) is a 175-hectare protected area that serves as a home to a wide array of mangroves and marine organisms, and a sanctuary for both local and migratory birds. However, its location deems strategic for anthropogenic activities, which makes it inclined to environmental degradation including lead contamination. This study assessed the quality of LPPCHEA’s waters through the measurement of the amount of lead present in the soft tissues of three mollusc species, namely: Nassarius sp., Perna viridis, and Crassostrea iredalei. Inter-and intraspecific variations in lead concentrations were analysed statistically in terms of weight, length, and width. Results showed significant interspecific differences between P. viridis and C. iredalei (p < 0.05). Significant intraspecific differences (p < 0.05) in terms of weight were found in P. viridis and C. iredalei; length and width in C. iredalei. It was also found out that the lead accumulated in the aforementioned species, exceeding the permissible limit of lead in fresh tissues for human and animal consumption set by the international standards, indicates that the marine organisms living in the area are unsafe for consumption
Schistosomiasis Snail Surveillance and Human Prevalence Geographic Information System
No full textSchistosomiasis is a water-borne parasitic disease endemic in tropical areas such
as the Philippines. Its transmission is dependent on the presence of intermediate
host snails. This study proposes a GIS that visually maps schistosomiasis prevalence in the Philippines by plotting infected snails and human cases by allowing fi eld workers to input snail sample information and by integrating with the DOH schistosomiasis system
Survival outcome of Aedes (Stegomyia) aegypti larvae exposed to varying dilutions of Bacillus thuringiensis var. israelensis (Bti) sero 14 spores.
No full textThe larvicidal action of Bacillus thuringiensis var. israelensis (Bti) Sero 14 spores was tested against Aedes (Stegomyia) aegypti fourth instar (L4) larvae, the primary vector of dengue fever in the Philippines. Treatments of Bti spore concentrations (1 mg/mL to 1 x 10-5 mg/mL) and distilled water (negative control) were prepared for two groups (with and without Purina feeds) to determine survival outcomes of L4 Aedes (Stegomyia) aegypti larvae. Life Tables Analysis with Wilcoxon (Gehan) Statistic pairwise comparison determined that Bti spore concentrations of 1 mg/mL, 1 x 10-1 mg/mL, and 1 x 10-2 mg/mL were lethal to Aedes (Stegomyia) larvae within 1.5 days compared to spore concentrations of 1 x 10-3 mg/mL, 1 x 10-4 mg/mL, 1 x 10-5 mg/mL, and negative control (p=0.001) for both groups. Pupal and adult emergence cases were only observed in larvae administered with Purina feeds and Bti Sero 14 spore concentrations of 1 x 10-4 mg/mL and 1 x 10-5 mg/mL. Thus, the spores of the Philippine Bti Sero 14 strain can be further explored as a biological control agent against larval Aedes (Stegomyia)
Makina at pakikibaka: sosyo-ekonomikong kalagayan at pampolitikang kamalayan ng kababaihang mananahi sa San Miguel, Bulacan.
No full textMasunurin, matiyaga, pasibo – ilan lamang ito sa pagsasalarawan sa mga kababaihan. Higit sa mga salita, ang mga istiryotipong ito na ikinakabit sa mga kababaihan ay ang siyang humuhubog sa pagtingin at pagtrato ng lipunan sa kanila. Ito rin ang nagtatakda ng kanilang magiging katayuan sa iba't ibang larangan, lalo na sa usapin ng empleyo. Nagpapatuloy ang kanilang pakikibaka laban sa makitid na pananaw na ito kasama ang mga salik na kumakasangkapan dito upang lalo silang mapagsamantalahan at pagkaitan ng karapatan. Upang maunawaan at mapalalim ang kaalaman ukol sa tunay na kalagayan ng mga kababaihang manggagawa, napiling maging sentro ng pag-aaral ang isa sa mga trabahong malimit na pinapasok nila – ang pananahi. Sa pamamagitan ng pakikisalamuha at pakikipag-ugnayan sa 15 kababaihang mananahi sa bayan ng San Miguel, probinsya ng Bulacan, nakita ang mga rural, kapitalista, at global na kondisyong kinapapalooban ng kanilang karanasan at kamalayan. Ang salimbayan ng pagiging babae, pagiging mahirap, at paninirahan sa pook-rural ang nagtulak sa mga kababaihan upang pasukin ang pagiging mananahi at pwersadong manatili rito sa kabila ng hindi makataong kalakaran sa loob ng patahian. Samantala, ang hindi makatarungang pasahod, at mga problemang pangkalusugan at pangkaligtasan na kinakaharap ng mga mananahi ang manipestasyon ng kanilang masahol na kalagayan bilang manggagawa. Batay naman sa kanilang mga testimonya, napagtibay na ang pinalalaganap na huwad na ideolohiya ang pumipigil upang kanilang makamit ang mataas na antas ng pampolitika at makauring kamalayan na mahalaga sa pagtataguyod ng kanilang interes. Ang apat na bahagi ng presentasyon ng datos na pinamagatang Espasyo, Retaso, Makina, at Pakikibaka, ang kumakatawan sa apat na sulok ng kahong binuo ng globalisadong industriya ng pananahi na lalong nagpakitid sa mundong ginagalawan ng mga kababaihang mananahi. Gayunpaman, ang konkretong kalagayan ng mga kababaihang mananahi na sumasalamin rin sa katayuan ng laksa-laksang mamamayan ay ang mismong magiging daan upang makamit ang makabuluhang panlipunang pagbabago
A Comparative study of two endemic limestone begonia species of Northern Palawan.
No full textBegonia of the family Begoniaceae is widely used for ornamentation because of its distinctly patterned leaves and flowers. Currently, there are 104 known Philippine species, 14 of which are located in Palawan thriving on limestone topographies. In this study, we reported a Begonia species in El Nido, Palawan which is observed to be very similar to Begonia wadei in Coron Island, Palawan. Both species were found to be different from the other members of the Begonia section Baryandra because of their suffrutescent stem and found in limestone crevices splashed with seawater compared with the other members, which prefer shaded, moist primary forest. Based on comparison of morphological, anatomical and molecular data, Begonia sp. of El Nido, Palawan was found to be a different species from Begonia wadei. The two species were morphologically different due to the asymmetric, clasping leaves and undulate leaf margin of B. sp. as compared to the subsymmetric, non-clasping leaves and denticulate leaf margin of B. wadei. Anatomical analysis also showed significant differences in terms of thickness of protective covering, width of interfascicular parenchyma between vascular bundles, length of vascular bundles and length of xylem tissues. Lastly, cladogram showed that B. sp. and B. wadei belong to two separate clades. This set of evidence may eventually lead to the identification of Begonia sp. as a novel species
Effect of a modified earthworm formulated feed (MEF) on the growth and development of juvenile giant freshwater prawns Macrobrachiumrosenbergii.
No full textThe use of commercial feeds for prawn aquaculture constitutes a significant investment amounting to approximately 40-60% of the total cost of operations (Mitra et al., 2005). This study aims to describe the effects of a modified earthworm-formulated feed (MEF) on the growth and development of juvenile M. rosenbergii prawns by comparing it to a brand of commercial feed. Two aquaria for the experiment (each with 39 prawns) were used: one was fed with modified earthworm formulated feed (MEF) and the other fed with the commercially-formulated feed (CF). Data was collected every week for 7 weeks, namely weight, length, width, survival. There was a slow but steady increase in the values of the weight, length and width of both treatments. The initial and final values of the two treatments for weight are 0.677g-1.902g for CF and 0.408g-1.294g for MEF, for length 48.699mm-60.028mm for CF and 38.046mm-51.028mm for MEF, lastly for width 7.791mm-10.399mm for CF while 6.224mm-8.639mm for MEF respectively. The CF feed fed prawns achieved significant gain in weight, length and width earlier compared to MEF-fed prawns. However, the differences in growth rate between the two test groups were not significant. The survival rate for the CF feed fed prawns was 79% while for MEF- fed prawns was 74%. Both survival rates were similar to the observed survival rates of Abdel-Hakim et al. (2013). In both test groups, behaviors observed such as preening, territoriality, zoning of available space, lack of communal interaction and isolation from other prawns revolved around the prawns exhibiting intraspecific competition for the limited resources. These behaviors observed were similar with those of Saravanan et al (2008)

Molecular and Morphological Evidence for Novel Begonia species from Puerto Princesa Subterranean River National Park
No full textMany endemic Begonia species are present in the Philippines especially in limestone, karst forests (Rubite, 2010). In a recent visit to Puerto Princesa Subterranean River National Park, three species of Begonia were found and were suspected to be novel. The study aimed to provide evidence that the suspected Begonia species are different from known species of Begonia by performing morphological and phylogenetic analysis. The morphological characters were recorded and compared to the closest known affinities of the suspected species. The ITS region of the nrDNA of the suspected novel species was sequenced and subjected to phylogenetic analysis. B. sp. nov. 1 closely resembles B. gutierrezii but differs in multiple morphological characters. ITS data for B. gutierrezii is unavailable so no molecular analysis was done. B. sp. nov. 2 closely resembles B. suborbiculata but differs by having a three-winged fruit. They form separate clades and have pairwise difference of 0.044. B. sp. nov. 3 closely resembles B. cleopatrae but differs in many morphological characteristics. They form separate clades and have pairwise difference of 0.035
Mobi-MAPP: A Mobile Application for Quick Alert and Monitoring of Disasters
No full textSeveral calamities have already been observed here in the Philippines. With its
geographic location, it is not surprising that the country has been considered as
one of the most disaster-prone in the world. In times of these disasters, that come
unpredictably, alertness and preparedness of the people is important as these could
prevent possible damages and save lives.
With the advent of modern technological tools and gadgets such as smartphones,
with its advanced computing ability and connectivity, it is not impossible to cre-
ate a mobile early warning system and quick monitoring for these kinds of disaster.
In this project, we propose a system called Mobi-MAPP, a mobile application
for quick alert and monitoring of disasters. Here, Mobi-MAPP users can send
their reports on a particular disaster situation through the application. Also, data
from di erent concerned local and national agencies are gathered. These data will
then be quickly re
ected on the Mobi-MAPPs interactive map which will display
di erent disaster information across the country. Mobi-MAPP also provides an
alert system wherein users are noti ed of nearby disaster. Mobi-MAPP also pro-
vides a means in which national disaster risk reduction and management units can
share disaster information and activate disaster response to a ected areas
