Edgardo E. Tulin,Zenaida T. Ecleo 한국식품영양과학회 2007 Journal of medicinal food Vol.10 No.2

This study evaluated Philippine indigenous plants for cytokine-mimetic properties and partially characterizedcandidate mimetics for their stability as well as their sensitivity to variations in temperature and pH. Forty-five plant extractpreparations were tested for their ability to stimulate proliferation of mouse spleen cells and bone marrow cells. Temperatureand pH effects were determined by subjecting the extracts to different temperature and pH levels and measuring their resid-ual proliferative activities. Results revealed that 24 and 14 extracts were able to stimulate proliferation of bone marrow cellsand spleen cells, respectively. Extracts from yam (Dioscorea alata L.) (Dioscoreaceae) roots and leaves, taro (Colocasia es-culenta L.) (Araceae) roots, and buyo (Piper betleL.) (Piperaceae) leaf were among the extracts that strongly stimulated pro-liferation of both bone marrow cells and splenocytes, significantly increasing cell concentrations. Heating the extracts beyond40°C markedly reduced their proliferative ability, while a pH level below 4.0 and above 8.0 also significantly decreased theextracts’ activity. Three protein-mimetics with sizes of 26 kDa, 35 kDa, and 50 kDa were isolated from buyo leaf, yam root,and taro root extracts, respectively. All three molecules are biologically active and stimulate a dose-dependent proliferativeresponse.

A Multidimensional View of SNS Usage: Conceptualization and Validation

Edgardo R. Bravo,Christian Fernando Libaque-Saenz 한국경영정보학회 2022 Asia Pacific Journal of Information Systems Vol.32 No.3

Social networking sites (SNSs) have become an essential part of people’s lives. It is thus crucial to understand how individuals use these platforms. Previous literature has divided usage into numerous activities and then grouped them into dimensions to avoid excessive granularity. However, these categories have not been derived from a uniform theoretical background; consequently, these dimensions are dispersed, overlapping, and disconnected from each other. This study argues that “SNS usage” is a complex phenomenon consisting of multiple activities that can be grouped into dimensions under the umbrella of communication theories and these dimensions are related to each other in a particular multi-dimensional architecture. “SNS usage” is conceptualized as a third-order construct formed by “producing,” “consuming,” and “communicating.” “Producing,” in turn, is proposed as a second-order construct manifested by “commenting,” “general information sharing,” and “self-disclosure.” The proposed model was assessed with data collected from 414 USA adult users and PLS-SEM technique. The results show empirical support for the theorized model. SNS providers now have this architecture that clarifies the role of each dimension of use, which will allow them to design effective strategies to encourage the use of these networks.

Edgardo P. Lillo,Edwino S. Fernando,Mary Jane R. Lillo 국립중앙과학관 2019 Journal of Asia-Pacific Biodiversity Vol.12 No.1

Logging, mining and land conversion together threaten Dinagat Island. Diversity and structure of foresthabitat types were determined as basis for conservation and management. Identification of forest habitattypes was based on habitat’s physical characteristics. Six forest habitat types were identified covered by 432 native plant species classified into 87 familiesand 203 genera, 40 plant species were endemic to Dinagat Island. Of the 432 species, 58% recorded inlowland evergreen forest (LEF), 16% in upper montane, 15% in forest over limestone, 6% in lower montaneforest (LMF), 4% in mangrove forest, and 1% in beach forest, with average species diversity of 3.32. Trees in LEF were bigger, taller and larger in basal area as compared with other habitat types. Dominant species was Xanthostemon verdugonianus Náves ex Fern.-Vill with importance value of 9.857%. Native plant species was an asset for the mineral resource industry for site rehabilitation andconservation.

Students’ Motivational Beliefs, Values and Goals as Related to Academic Hardiness : Implications to Mathematics Teaching and Learning

Edgardo M. Santos ASCONS 2018 INTERNATIONAL JOURNAL OF EMERGING MULTIDISCIPLINAR Vol.2 No.1

The study examined the relationship between the Academic Hardiness and Motivational Beliefs, Goals and Values of tertiary students towards mathematics learning. The respondents of the study consist of about 167 BS Mathematics third year students of the Bulacan State University during Academic Year 2016-2017. The descriptive – correlational method of research was employed in the study. To gather the necessary data, the researcher adopted two instruments - the Academic Hardiness Scale developed by Benishek and Lopez (2001) and the Learning Motivation Questionnaire, a section from the Motivated Strategies for Learning Questionnaire (MSLQ) developed by Duncan and McKeachie (2005). Pearson correlation analysis and Test of significance were used to interpret the results. The study showed that among the three related attitudes of Academic Hardiness (Commitment, Control and Challenge), the students posted the highest mean in the Commitment domain. Seemingly, the difficulty posed by mathematics has not negated students’ interest and involvement in doing their mathematical tasks. Regarding the status of the students’ Motivational Beliefs, Goals and Values toward mathematics learning, results yielded a high overall mean rating reflective of the high ratings received in almost all the motivational constructs: Intrinsic Goal Orientation, Extrinsic Goal Orientation, Task Value, Controls of Learning Beliefs, Self-Efficacy for Learning and Performance except Test anxiety. The highest perceived mean is on Task Value which demonstrates the respondents expressed interest in mathematics and their acknowledge importance of the subject in their preparation to life-long learning. For Test Anxiety, perceived mean rating is average. This result simply reiterates the psychological distress experienced by students when taking examinations in mathematics. Lastly, analysis also showed that students’ Academic Hardiness and the identified motivational constructs has significant positive correlation with each other.

Locating the Filipino as Malay: A Reassertion of Historical Identity from the Regional Periphery

José Edgardo Abaya Gomez Jr. 서강대학교 동아연구소 2020 TRaNS(Trans –Regional and –National Studies of Sou Vol.8 No.2

In Malaysia, Brunei, Singapore, and Indonesia, being Malay usually means being a practitioner of Islam and a speaker of standard Bahasa. However, such understandings no longer comprehend other members of the so-called brown-skinned race who were once united with the Malay aggrupation: numerous Filipinos (and East Timorese), who inhabit the same broad geopolitical region. Challenging the recent narrowly defined conceptions of who is, or was Malay, this study recalls an inclusive borderless understanding acquired in antiquity by the Filipino nation, whose peoples were considered by Spanish and American colonisers and educated by their government to consider themselves as part of a pre-modern “Malay” world. Geohistorical evidence shows how such auto-consciousness evolved and preceded the entry of the term into the nearby British colonisers’ lexicon, before its social-reconstruction for the perpetuation of post-colonial polities as well. The author interweaves his textual survey with the problematisation of the location of ethnicity, and points out the seemingly neglected corpus of Iberian works that demonstrate how the knowledge of Malayness could only have been approached by Europeans from a geographic periphery, of which the Philippine archipelago was very much a part, especially the Mindanao area. The author builds on and constructively critiques work by one scholar who had initiated the claims of the Filipino to Malayness. It is shown how sociocultural and geopolitical priorities can help or hinder the relaxation of definitions of who is Malay and where Malays are properly situated, if only because these counter perceptual rigidities, and allow the creation of hybrid third spaces that admit new possibilities of coexistence.

Wind and Gust Forecasts Assessment of Weather Research and Forecast (WRF) Model in Córdoba, Argentina

Matías Suárez,Denis Poffo,Edgardo Pierobon,Agustín Martina,Jorge Saffe,Andrés Rodríguez 한국대기환경학회 2022 Asian Journal of Atmospheric Environment (AJAE) Vol.16 No.1

WRF wind forecasts from four operative schemes used by OHMC (Observatorio HidroMeteorológico de Córdoba), a test scheme (WRF-E) and two daily runs with 4 km horizontal resolution were analyzed. Wind simulations were compared with measurements from eight ground stations with anemometers at 10 m high during the period from June, 2019 to June, 2020. WRF-E incorporates more vertical levels, and an activated topo_wind option. The wind speed results show that WRF overestimates wind speed at most stations and the WRF-E model reduces the BIAS and the RMSE when compared with the operational models. The wind direction analysis shows that the higher the wind speed is, the more accurate the models are. In addition, a wind gust forecasting has been implemented and evaluated in this work. Wind gust correlation coefficient values are between 0.3 and 0.6, RMSE is between 3 and 5 m/s, and a positive BIAS (<2 m/s) at most stations.

Burkholderia tropica as a Potential Microalgal Growth-Promoting Bacterium in the Biosorption of Mercury from Aqueous Solutions

The use of microalgal biomass is an interesting technology for the removal of heavy metals from aqueous solutions owing to its high metal-binding capacity, but the interactions with bacteria as a strategy for the removal of toxic metals have been poorly studied. The goal of the current research was to investigate the potential of Burkholderia tropica co-immobilized with Chlorella sp. in polyurethane discs for the biosorption of Hg(II) from aqueous solutions and to evaluate the influence of different Hg(II) concentrations (0.041, 1.0, and 10 mg/l) and their exposure to different contact times corresponding to intervals of 1, 2, 4, 8, 16, and 32 h. As expected, microalgal bacterial biomass adhered and grew to form a biofilm on the support. The biosorption data followed pseudo-second-order kinetics, and the adsorption equilibrium was well described by either Langmuir or Freundlich adsorption isotherm, reaching equilibrium from 1 h. In both bacterial and microalgal immobilization systems in the coimmobilization of Chlorella sp. and B. tropica to different concentrations of Hg(II), the kinetics of biosorption of Hg(II) was significantly higher before 60 min of contact time. The highest percentage of biosorption of Hg(II) achieved in the co-immobilization system was 95% at pH 6.4, at 3.6 g of biosorbent, 30 ± 1°C, and a mercury concentration of 1 mg/l before 60 min of contact time. This study showed that co-immobilization with B. tropica has synergistic effects on biosorption of Hg(II) ions and merits consideration in the design of future strategies for the removal of toxic metals.
