Ovitrap surveillance of Aedes (Stegomyia) aegypti (L.) in selected areas in the City of Manila, Philippines.
No full textBaseline information is provided on the larval density of Aedes (Stegomyia) aegypti (L.) populations in two urban communities in the City of Manila, Philippines, named Barangay 690 and Barangay 693, with varying vegetation densities, drainage systems, and waste disposal practices. Ovitrap surveillance was conducted in twenty households at four-day intervals for six consecutive trials using three ovitrap designs. Populations of Ae. aegypti were detected in the study areas with a mean larval density count of 26.7, a total larval density count of 1389, Ovitrap Index (OI) of 46.8%, and House Index (HI) of 84.2%. A field evaluation of the larvicidal effects of pelletized fruits of Piper nigrum and sundried leaves of Lansium domesticum was performed. Results showed that P. nigrum type ovitraps consistently yielded lower OI, HI, total and mean larval density counts than both the untreated control type and L. domesticum type ovitraps, although the difference was not statistically significant (p = 0.19). There were no significant differences in mean larval densities of indoor and outdoor ovitraps (p = 0.15) and ovitraps placed in Barangay 690 and Barangay 693 (p = 0.18). This indicates that breeding and larval populations of Ae. aegypti are consistently present throughout the study areas
Comparison of plant diversity between native and non-native tree plantations in the La Mesa Nature Reserve.
No full textThe La Mesa Nature Reserve (LMNR) has been a site of reforestation projects over the years. Reforestation stands in the area includes plantation of mixed and monoculture of either native or non-native trees. Monoculture native tree plantation has been observed to harbor the same diversity as the nearby primary forest (Lima and Vieira, 2013). To investigate the plant diversity between monoculture native and non-native tree plantations in LMNR, a vegetation survey was conducted in Narra and Mahogany plantations. Plots were established in each plantation and the list of trees and understory plants found in Narra and Mahogany plantations were recorded. The importance values and diversity indices such as Simpson’s index (1-D), Shannon-Wiener index (H), and Fisher’s alpha Diversity index were computed to describe the diversity in the plots. The diversity indices between two plantations were then computed using t-test. The result showed that the diversity values of Narra and Mahogany plantations are similar. However, results also showed that each plantation has unique floristic compositions. The Narra plantation contains more native fleshy fruit-bearing tree species than the Mahogany plantation. It could have attracted dispersal agents such as birds or bats which play an important role in forest regeneration. Furthermore, the Narra plantation acquired a higher number of unique native tree species compared to the Mahogany plantation
Online Student Evaluation of Teachers (OSET) 4.0: Data Collection and Anonymization
No full textWith an OSET that allows for the exporting of the student answers, it would
be possible to use the system itself as a platform to test the effectiveness of a
SET instrument. Since the data set of responses will be de-identified, they cannot be associated or linked to a particular respondent, protecting the privacy of the students. The used of module-based questions would also be a new feature of the system which will offer greater flexibility in modifying the SET instrument

This study proposes a monitoring information system with the aid of geographic information system maps to help health offi cials in the surveillance of these diseases and for the immediate response and intervention
Section of Pediatric Gastroenterology, Hepatology, and Nutrition's Out-Patient Database System
No full textMonitoring patient records manually has been quite a problem ever since. Human errors are inevitable that may lead to false records. The system speci fically designed for PGH's Section of Pediatric Gastroenterology, Hepatology, and Nutrition aims to
improve the storage and utilization of medical records originally written on paper by providing an electronic means of taking in forms to be used for data retention, data gathering and report generation. The data in the system can be used for scientifi c research and to keep track of the patient's medical history for signs and previous occurrences of malnutrition via growth charts
Cytotoxicity assessment of organic extracts obtained from indoor air dust from selected primary public school buildings in Metro Manila, Philippines on A549 human adenocarcinoma epithelial cell lines.
No full textEstablishments located in Metro Manila are repositories for various environmental contaminants harboring in indoor air dust making it the most significant source of exposure particularly for children. This study aimed to assess the cytotoxicity potential of organic compound-laden indoor extracts from a primary public school in Navotas City, Philippines using the MTT (3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyltetrasodium bromide) assay. The indoor air dust samples were extracted with the use of methanol: ethyl acetate solvent to produce pure compounds that were then further identified using Gas Chromatography-Mass Spectrometry. These organic acids were tested to A549 human adenocarcinoma epithelial cell line using the MTT assay. Results showed that organic components include various alkanoic acids, n-alkanes, a phthalate, and a lanostene triterpenoid coming from both biogenic and anthropogenic emissions. The organic compounds exhibited strong cytotoxic activity (IC50 well above the maximum IC50 = 7.1542 µg/ml) that is threshold (30 µg/ml) set by the American National Cancer Institute for determining compounds with cytotoxic capabilities
Isang kritikal na pag-aaral ukol sa epekto ng malawakang pagpapalit-gamit ng lupa sa kita at pang-ekonomikong kasiguruhan ng mga pesante sa barangay Santiago ng General Trias, Cavite
No full textHanggang sa kasalukuyan, laganap pa rin ang mga pagpapalit-gamit ng lupa sa Pilipinas at isa ang probinsya ng Cavite sa dumadanas nito. Bagamat mayroon nang mga pag-aaral ang nagawa ukol sa pagpapalit-gamit ng lupa sa ibang bahagi ng Cavite, napag-iiwanan ang munisipalidad ng General Trias pagdating sa usaping ito. Tiningnan ng pag-aaral na ito ang epekto ng pagpapalit-gamit ng lupa sa General Trias partikular na sa barangay Santiago. Upang malaman ang mga epekto ng pagpapalit-gamit ng lupa, gumamit ng sariling questionnaire ang mananaliksik at ipinasagot sa limampung pesante. Nakipanayam din ng mga kinatawan ng isang pangmasang organisasyon—KAMAGSASAKA-KA, at isang kinatawan mula sa lokal na pamahalaan ang mananaliksik upang mas maintindihan pa ang pagpapalit-gamit ng lupa sa lugar. Epekto sa kita, pang-ekonomikong kasiguruhan (economic security), at pangangamkam ng lupa ang sentro ng pag-aaral. Ipinakita sa resulta na marami sa mga pesante (38%) ang nanatili sa dati ang kinikita matapos ang pagpapalit-gamit ng lupa bagaman dumami ang bilang ng pesanteng tiyak na mas mababa pa sa minimum wage ang kita (mula 22% tungong 52%). Sa kabila ng pagpapalit-gamit ng lupa, marami sa kanila ang nanatiling magsasaka (36%). Ipinakita sa resulta na maraming pesante ang naniniwalang hindi pangmatagalan ang mabuting dulot ng pagpapalit-gamit ng lupa(66%). Dahil dito, nagkaroon sila ng impermanence syndrome o kawalan ng kumpyansa sa katatagan at pangmatagalang silbi ng pagsasaka kaya ang kanilang naipon ay ipinundar nila sa ibang pagkakakitaan(28.66%). Walang naiulat na pangangamkam ng lupa sa barangay Santiago bagaman 62% sa mga nagsagot ay walang sariling lupa
Danger zone to death zone: a case study on the relocated families in Bayan ni Juan before and after the Estero de Paco Project.
No full textThe country’s waterways have long been victimized by improper waste disposal by residential and industrial establishments. Pasig River that was once a center of trade and carries the nation’s history and culture has turned into a national symbol of pollution. Though there were efforts to save the river, it is ironic that the lives of the people were traded for its survival. This study examines the rehabilitation and relocation program of the government. It is made possible through conducting survey and interviews with key informants. Reports, journals, news and necessary materials are evaluated to support arguments. Results show that in Bayan ni Juan relocation site, residents turned into temporary and low-income workers, health became luxury while necessities turned commodities. Thus, it is mandatory to create concrete and long-term plan for the resettler’s sustenance
Anti-hyperglycemic effect of Ficusulmifolia Lam. (Moraceae) crude leaf extract on the blood and urine glucose levels of mice fed on a high carbohydrate diet.
No full textThe study aims to assess Ficus ulmifolia as a possible alternative source of antihyperglycemic agent. In order to test if F. ulmifolia crude leaf extract can lower blood glucose levels in a person with diabetes, a temporary hyperglycemic condition was induced in the mice. A high carbohydrate diet was provided to the test mice for 21 days, followed by administration of the F. ulmifolia leaf extract at doses 100 mg/kg and 1000 mg/kg and metformin at 150 mg/kg for 14 days. Each mouse then orally received 70% glucose and blood glucose levels were monitored. Results showed that the oral administration of 100 mg/kg of F. ulmifolia leaf extract lowered blood glucose levels by 2.5% relative to the group that received no extract while the ingestion of the 1000 mg/kg extractsignificantly decreased blood glucose concentration by 47.5% relative to the group that received no extract. The blood glucose levels of the group that were orally administered with 1000 mg/kg of the plant extract were significantly different from that of the untreated group and the group that received 100 mg/kg of the extract. However, there were no significant differences in blood glucose levels of the mice which received 1000 mg/kg and the mice which received 150 mg/kg of metformin, indicating that the two treatments have similar hypoglycemic effects. There was minimal glucose excretion observed in the test mice, suggesting that other mechanisms are involved in the reduction of blood glucose levels of F. ulmifolia. The findings of the studydemonstrate that the dietary supplementation of the crude leaf extract of F. ulmifoliahas blood glucose lowering effectson mice fed on a high carbohydrate diet
Lung Cancer Classification Tool Using Microarray Data and Support Vector Machines
No full textLung cancer is one of the deadliest types of cancer in country and around the world. Epidemiologic studies have shown that genetic variability is among the factors that affect a person’s susceptibility to lung cancer. This study proposes a system that will utilize gene expression data to predict the presence or absence of lung cancer, predict the specific type of lung cancer should it be present, and determine marker genes that are attributable to the specific kind of the disease. The proposed system would help in the faster diagnosis and serve as a reliable adjunct approach to current lung cancer classification methods
