Don Mariano Marcos Memorial State University
Bacnotan, Philippines

The Don Mariano Marcos Memorial State University, more often referred to by the acronym "DMMMSU" is the state university serving the province of La Union in the Philippines. Its main campus is in Bacnotan, La Union. It was created by former president Ferdinand Marcos by using Presidential Decree 1778 to combine a number of state-run schools in La Union into a single state college in 1981. Like Mariano Marcos State University in Ilocos Norte, it is named for the former president's father, Mariano Marcos.Before 1993, DMMMSU occupied seven campuses throughout the province. After a reorganization that year, these campuses were grouped into three administrative units, simply called the North La Union Main Campus , the Mid La Union Campus , and the South La Union Campus . Each unit is headed by a chancellor, while the whole system is headed by the university president Atty. Benjamin P. Sapitula . Wikipedia.

This study seeks to assess the groundwater and leachate quality in Balaoan sanitary landfill using physicochemical and biological parameters and to compare the results to quality standards. Groundwater and leachate samples were collected through grab sampling during the months of February and April and sent for laboratory analyses. Except for the Total coliform and E. coli counts, the physico-chemical parameters of the groundwater samples such as pH, turbidity, total dissolved solids, and nitrate were found to conform to the Philippine National Standards for Drinking Water (PNSDW). Leachate samples in terms of pH, chemical oxygen demand were found to conform to the regulatory limit while toxic metals such as cadmium, chromium, copper, lead and mercury showed very low concentration based on DAO 35, series of 1990 Class C waters. Groundwater samples from tube wells near the sanitary landfill are no longer safe for human consumption. Copyright © 2017, AIDIC Servizi S.r.l..

This research study deals with the formulation of an algorithm in finding lucky primes while methodically testing the primality of each. New and different behaviors of lucky primes and related concepts have been explored and exploited to come up with underlying propositions that were supported by proofs made by the researchers. Using these properties, the researchers developed a computer application using the Python programming language in order to generate lucky primes up to certain limit. They tested the viability of using lucky primes as a substitute cryptovariable in a computer program that implements the RSA cryptosystem in encrypting and decrypting messages. © 2016 Author(s).

This study analyzes the dynamics of the socio-ecological system of Baguio City, the summer capital of the Philippines, in order to derive meaningful information for use in planning its sustainable development. Remote sensing data and geographic information systems techniques, in conjunction with spatial metrics and socio-economic information, were used to facilitate the analysis. The spatial and socio-economic components of Baguio's rapid urbanization over the past 21 years (1988-2009) were the major factors that contributed to dramatic changes in the setting's natural landscape, as indicated by an almost threefold increase in its built-up area, at the expense of other land-use/land-cover classes. Its rapid growth has seen the city's population exceed its designed ceiling of 25,000 people by a factor of at least twelve. Such landscape changes and population growth have resulted in a substantial decrease in the overall annual ecosystem service value (ESV) of Baguio of approximately 60%. The human-to-ESV ratio in the city has also decreased over this same period, from 1:31 (US$/year) in 1988 to just 1:7 in 2009. Although Baguio has enjoyed economic, political and social prominence for more than a century, its rapid population growth and urban expansion are now exerting pressure on its natural landscape, jeopardizing the environmental sustainability of this highly valued hill station. This study offers important insights to all, but especially those in fast-urbanizing regions, as Baguio's case offers learning experience valuable for achieving more successful landscape and urban planning. © 2013 Elsevier B.V.

The main purpose of this study is to examine the potential impacts of the past and future land use/cover (LUC) changes on the ecosystem services of Baguio city, the Philippines, and discuss their implications for policy development and implementation. Remote sensing-derived LUC maps for 1988, 1998 and 2009, along with GEOMOD, a Geographic Information Systems-based LUC change model, and ecosystem service value (ESV) coefficients were used to facilitate the analysis. The results revealed a decrease in the ESV of Baguio for the past 21 years (1988-2009), of which a substantial amount was due to loss of forest cover. Consequently, the human-to-ESV (H-ESV) ratio has decreased over the years. The scenario-based LUC change analysis revealed that if the urban LUC change pattern continues, the total ESV and the H-ESV ratio will also continue to decrease in 2020, especially if the forest cover is not fully protected and conserved. Geospatial tools and techniques facilitate exploratory analysis critical to the understanding of the potential impacts of future LUC changes under different scenarios. Our results highlighted that under the great pressure of urbanization, there is a need to strengthen the proper implementation of policies in order to maintain and improve ecosystem services. Although there are limitations to the estimated ESVs of Baguio to be taken into account in future studies, the magnitude of the estimated changes in the LUC is substantial. Thus, it may still be possible to draw general inferences about the effect of the perceived LUC changes on the estimated ESVs. © 2012 Elsevier Ltd.

Leaf extracts of Cassia alata L (akapulko), traditionally used for treatment of a variety of diseases, were evaluated for their potential antitumor properties in vitro. MTT assays were used to examine the cytotoxic effects of crude extracts on five human cancer cell lines, namely MCF-7, derived from a breast carcinoma, SK-BR-3, another breast carcinoma, T24 a bladder carcinoma, Col 2, a colorectal carcinoma, and A549, a nonsmall cell lung adenocarcinoma. Hexane extracts showed remarkable cytotoxicity against MCF-7, T24, and Col 2 in a dose-dependent manner. This observation was confirmed by morphological investigation using light microscopy. Further bioassay-directed fractionation of the cytotoxic extract led to the isolation of a TLC-pure isolate labeled as f6l. Isolate f6l was further evaluated using MTT assay and morphological and biochemical investigations, which likewise showed selectivity to MCF-7, T24, and Col 2 cells with IC50 values of 16, 17, and 17 μg/ml, respectively. Isolate f6l, however, showed no cytotoxicity towards the non-cancer Chinese hamster ovarian cell line (CHO-AA8). Cytochemical investigation using DAPI staining and biochemical investigation using terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL)-a method used to detect DNA fragmentation-together with caspase assay, demonstrated apoptotic cell death. Spectral characterization of isolate f6l revealed that it contained polyunsaturated fatty acid esters. Considering the cytotoxicity profile and its mode of action, f6l might represent a new promising compound with potential for development as an anticancer drug with low or no toxicity to non-cancer cells used in this study.

Free radicals have significant effects on the structure and general function of the cell. They play a role in the body's defense against infection by microorganisms. At the same time, they cause a number of diseases by inducing damage to DNA and other important biomolecules. Hence, the search for additional free radical scavengers or antioxidants, especially from plant sources, is of prime importance. Leaf extracts from Cassia alata L. (locally known as 'akapulko'), traditionally used for the treatment of a variety of diseases, were evaluated as free radical scavengers using the diphenyl picryl hydrazyl hydrochloride (DPPH) assay. The ethyl acetate (EtOAc) fraction showed scavenging activity of 100%, comparable to gallic acid, a widely used antioxidant. Repeated column fractionation of the EtOAc fraction yielded a new indole alkaloid, 1-(4'-hydroxyphenyl)-2,4,6-trihydroxy-indole-3-carboxylic acid, which demonstrated a dose-dependent scavenging activity against DPPH with an IC 50 of 0.0311 μM ± 0.002, indicating strong antioxidant potential.

Geographic Information System (GIS) has been proven in many studies and experiences to aid in the decision-making process based on Multi-Criteria Evaluation (MCE) techniques. This study aims to evaluate the suitability of the Province of La Union, Philippines for beekeeping using GIS and MCE techniques. This study presents an empirical method for suitability analysis involving GIS and the participation of stakeholders and experts in the decision-making process. The empirical conceptual model used in this study contains three main components: database creation and management; spatial and multi-criteria analysis and validation process. As an integral part of the model, the final suitability map was validated through a correlation analysis method involving the existing beekeeping projects honey yield data and the calculated suitability values. Results showed relatively high correlation between the suitability index and honey yield. This indicates some degree of reliability of the model used and the output produced. The results of this study may be used as a basis in evaluating the suitability of other areas for beekeeping. It may also serve as a take-off board for more complex studies in the future. © Medwell Journals, 2010.

This study evaluated the psychometric properties of the Filipino versions of the Duke University Religion Index (DUREL-F) and the Spiritual Coping Strategies scale (SCS-F) for hemodialysis (HD) patients in the Philippines. A convenient sample of 162 HD patients was included in this descriptive, cross-sectional study. The DUREL-F and SCS-F exhibited acceptable internal consistency and stability reliability, as well as excellent content and construct validity. The findings confirmed the soundness of the psychometric properties of the two scales. Thus, they can be used for timely and accurate assessment of religiosity and spiritual coping utilization among Filipino patients receiving HD.

With the continued emigration of Filipino nurses and increasing globalization, there is a need for globally competent nurses. Thus, the development of cultural competence among nursing students is critical in their preparation to assume their future responsibilities in the profession.This study investigated the predictors of cultural competence among nursing students in the Philippines.This is a descriptive, cross-section study.This study included 332 Bachelor of Science in nursing students in three nursing schools situated in the northern Philippines.The Cultural Capacity Scale was used to gather data from the respondents. The demographic characteristics and cultural background of the students were entered in a regression analysis to predict their cultural competence.The respondents manifested appreciably good cultural competence with a mean score of 68.9811.73. The ability to understand the beliefs of various cultural groups received the highest mean of 3.650.86, while the ability to identify the care needs of patients with diverse cultural backgrounds received the lowest (mean, 3.310.74). Living in an environment with culturally diverse people, prior diversity training, being in the latter years of the nursing program, and with experience of caring for patients from diverse cultures and special population groups, were identified as predictors, accounting for 68.1% of the variance of cultural competence.Nursing education should devise strategies to ensure future culturally competent Filipino nurses. Considering the fact that most of the Filipino nurses will potentially work overseas, they should be well prepared to provide competent care that is culturally sensitive.
