In a constantly changing environment, accountants must not only acquire technical accounting knowledge and skills, but also acquire integrity, objectivity and the skills that enable them to take a firm stand in difficult situations. The purpose of this study is to know how to effectively incorporate business ethics in the Bachelor of Science in Accountancy (BSA) curriculum at De La Salle University (DLSU), Manila. Discussions in this paper focused on the responses of the students on what teaching strategies may prove to be effective when teaching business ethics subjects. Results of this study revealed that students ranked as the most effective the teaching strategy sub-group learning through ethical discussion and collaborative learning followed by the lecture method. Role playing and/or film viewing was ranked third. Inviting guest speaker for practitioner participation, case study method, personal value journals, and service learning were ranked fourth, fifth, sixth and seventh respectively. It is interesting to note that students ranked last/eighth the teaching strategy using the technology-enhanced learning or E-learning when teaching business ethics. This can give us an idea that even though the current generations of students are adept in using the computer and the Internet, they would still prefer actual classroom experiences in learning ethics courses. 展开更多

Cardiac disease is a chronic condition that impairs the heart’s functionality.It includes conditions such as coronary artery disease,heart failure,arrhythmias,and valvular heart disease.These conditions can lead to serious complications and even be life-threatening if not detected and managed in time.Researchers have utilized Machine Learning(ML)and Deep Learning(DL)to identify heart abnormalities swiftly and consistently.Various approaches have been applied to predict and treat heart disease utilizing ML and DL.This paper proposes a Machine and Deep Learning-based Stacked Model(MDLSM)to predict heart disease accurately.ML approaches such as eXtreme Gradient Boosting(XGB),Random Forest(RF),Naive Bayes(NB),Decision Tree(DT),and KNearest Neighbor(KNN),along with two DL models:Deep Neural Network(DNN)and Fine Tuned Deep Neural Network(FT-DNN)are used to detect heart disease.These models rely on electronic medical data that increases the likelihood of correctly identifying and diagnosing heart disease.Well-known evaluation measures(i.e.,accuracy,precision,recall,F1-score,confusion matrix,and area under the Receiver Operating Characteristic(ROC)curve)are employed to check the efficacy of the proposed approach.Results reveal that the MDLSM achieves 94.14%prediction accuracy,which is 8.30%better than the results from the baseline experiments recommending our proposed approach for identifying and diagnosing heart disease. 展开更多

Vaccination plays a vital role in protecting against communicable infections like measles and their associated complications[1,2].While vaccination doesn't guarantee complete immunity,the authors also highlighted that vaccinated individuals tend to experience milder infections compared to those who are unvaccinated[1].Despite the availability of free vaccines for measles,polio,and pertussis through the national vaccination program[3],the Philippines faced outbreaks of measles and pertussis across its islands in 2024[4].The Bangsamoro Autonomous Region in Muslim Mindanao reported 500 measles cases,while pertussis outbreaks were recorded in various parts of Luzon and Visayas,prompting several cities to declare states of calamity[4,5].Additionally,despite successfully eradicating poliomyelitis in 2000,approximately 70 percent of provinces and cities remained at high risk of polio outbreaks[3,4]. 展开更多

Objective: To explore cytotoxicity of Synsepalum dulcificum(S. dulcificum) Daniell(Sapotaceae) on human colon cancer(HCT-116 and HT-29), human monocytic leukemia(THP-1) and normal(HDFn) cell lines, and its effect on the expression of early apoptotic genes, c-fos and c-jun. Methods: Leaf, stem and berry of S. dulcificum were separately extracted by using 2 solvents, 10% ethanol(EtOH) and 80% methanol(MeOH). PrestoB lue~? cell viability assay and q RT-PCR assay were conducted to examine the above objectives respectively. Results: Stem MeOH, stem EtOH, and berry EtOH extracts of S. dulcificum were cytotoxic to HCT-116 and HT-29 human colon cancer cells. For HCT-116, IC_(50) values of these 3 extracts were not significantly different(P>0.05) from that of the positive control bleomycin(IC_(50) of 33.57 μg/mL), while for HT-29, IC_(50) values of these 3 extracts were significantly lower(P<0.05) than that of bleomycin(IC_(50) of 25.24 μg/mL). None of the extracts were cytotoxic to the THP-1 monocytic leukemia cells and HDFn normal human dermal fibroblasts. For both HCT-116 and HT-29, these extracts significantly up-regulated(P<0.05) the expression of c-fos and c-jun compared to the untreated negative control. Conclusions: The results of this study suggest that cytotoxicity of stem MeOH, stem EtOH, and berry EtOH extracts of S. dulcificum on HCT-116 and HT-29 colon cancer cells is due to the induced apoptosis which is caused by the up-regulation of the expression of early apoptotic genes, c-fos and c-jun. 展开更多

The underfloor air distribution(UFAD)system has not been able to penetrate the residential and commercial air conditioning industry significantly until now.To date,the most notable applications are found in datacenters because of their more demanding thermal stratification and cooling requirements.In addition to highlighting the advantages of the UFAD system over the traditional overhead(OH)system,this study compares various ventilation layouts for a UFAD system.Four different UFAD ventilation layouts are compared and one OH layout.The results show that using multiple swirl-type diffusers creates a more uniform floor-to-knee temperature and less air recirculation than the rectangular grille-type diffusers.Placing the return vents on the sides of the room creates a cooler environment by isolating recirculating air to a smaller space.At the end of the study,a design guide matrix is presented to summarize how the supply and return vent layout affects air conditioning performance. 展开更多

China’s swift and substantial economic growth over the past 20 years has made the country one of the top industrial powers in the world, second only the United States. From the perspective of ecology and the impact on the environment produced by economic and industrial growth, the exports that have driven rapid growth have also resulted in an alarming level of environmental pollution in major Chinese cities. Research has shown that the Chinese government’s investment in bringing down pollution levels has been insufficient and ineffective. The monetary amount allocated for pollution reduction has barely reached 0.15% of the country’s GDP and has failed to meaningfully reverse the effects of industrialization, including increased exports and economic growth rates affecting China’s ecology. The present study investigated China’s ecological situation in terms of the industrial production that has generated its level of exports, with special focus on problems related to water, air, and solid waste. An econometric analysis was conducted to determine the relationship between the main variables. The exports and GDP (dependent variable), air pollution, water pollution, and industrial solid waste (independent variables) were provided by the Institute of Statistics and the Environment Institute of China for this study. The data was managed in Econometric Eviews 7.0 software and yielded an adjusted R<sup>2 </sup>of 96.09% (high correlation) with an interesting correlation between the exports and three independent variables;after subsequent variable analysis, we found that investments in water and industrial solid waste were not significant (i.e., that said investments have failed to solve the pollution problem). It is necessary to review the Chinese investment policy with special attention to these variables to appropriately respond to China’s ecological crisis. 展开更多

Tourism is rapidly becoming a sustainable pathway toward economic prosperity for host countries and communities. Recent advances in information and communications technology, the smartphone, the Internet and Wi-Fi have given a boost to the tourism industry. The city bus tour (CBT) service is one of the most successful businesses in the tourism industry. However, there exists no smart decision support system determining the most efficient way to plan the itinerary of a CBT. In this research, we report on the ongoing development of a mobile application (app) and a website for tourists, hoteliers and travel agents to connect with city bus operators and book/purchase the best CBT both in terms of cost and time. Firstly, the CBT problem is formulated as an asymmetric sequential three-stage arc routing problem. All places of interest (PoI) and pickup/dropout points are identified with arcs of the network (instead of nodes), each of which can be visited at least once (instead of exactly once). Secondly, the resulting pure integer programming (IP) problem is solved using a leading optimization soft- ware known as General Algebraic Modeling System (GAMS). The GAMS code developed for this project returns: (1) the exact optimal solution identifying the footprints of the city bus relative to all the arcs forming the minimal cost network; (2) the augmenting paths corre- sponding to the pickup stage, the PoI visiting stage and the drop-off stage. Finally, we demonstrate the applicability of the mobile app/website via a pilot study in the city of Melbourne (Australia). All the computations relative to the initial tests show that the ability of the app to answer users' inquiries in a fraction of a minute. 展开更多

Objective: To evaluate the effects of lead in the morphology and viability of Fasciola gigantica(F. gigantica)(giant liver fluke) isolated from infected livers of carabaos in vitro using the following concentrations of lead: 0, 100, 150 and 200 mg/L. Methods: In vitro viability and motility assay was conducted to evaluate the ef ects of lead using 1% methylene blue as the vital dye for assessment of the l ukes' viability. Results: Results indicate that F. gigantica can tolerate lead exposure as high as 200 mg/L with visible morphological variations. Upon exposure to lead, liver l ukes tend to curl and excrete black precipitates as a sign of physiological stress response. Furthermore, the lethal concentration(LC50) of lead against F. gigantica in vitro was 160 mg/L. Conclusions: In conclusion, tolerance of liver flukes to high levels of lead suggests its potential as a possible biomarker of environmental pollution. 展开更多

Objective: To investigate the antibacterial activities of crude ethanol extracts of 12 Philippine medicinal plants.Methods: Crude ethanol extracts from 12 Philippine medicinal plants were evaluated for their antibacterial activity against methicillin-resistant Staphylococcus aureus, vancomycinresistant Enterococcus, extended spectrum β-lactamase-producing, carbapenem-resistant Enterobacteriaceae and metallo-β-lactamase-producing Pseudomonas aeruginosa and Acinetobacter baumannii. Results: The leaf extracts of Psidium guajava, Phyllanthus niruri, Ehretia microphylla and Piper betle(P. betle) showed antibacterial activity against the Gram-positive methicillinresistant Staphylococcus aureus and vancomycin-resistant Enterococcus. P. betle showed the highest antibacterial activity for these bacteria in the disk diffusion(16-33 mm inhibition diameter), minimum inhibitory concentration(19-156 μg/m L) and minimum bactericidal concentration(312 μg/m L) assays. P. betle leaf extracts only showed remarkable antibacterial activity for all the Gram-negative multidrug-resistant bacteria(extended spectrum β-lactamaseproducing, carbapenem-resistant Enterobacteriaceae and metallo-β-lactamase-producing) in the disk diffusion(17-21 mm inhibition diameter), minimum inhibitory concentration(312-625 μg/m L) and minimum bactericidal concentration(312-625 μg/m L) assays. Conclusions: P. betle had the greatest potential value against both Gram-negative and Grampositive multidrug-resistant bacteria. Favorable antagonistic activities were also exhibited by the ethanol extracts of Psidium guajava, Phyllanthus niruri and Ehretia microphylla. 展开更多

Difference in sub-cellular trafficking of glycosylated and naked peptides, between normal and lung cancer cells, was established. Normal lung tissue discriminately sorted glycosylated from non-glycosylated peptides by allowing golgi localization of the glycosylated peptides while restricting golgi entry of the naked peptides. This mechanism was surprisingly not observed in its cancer cell counterpart. Lung cancer cells tend to allow unrestricted localization of both glycosylated and naked peptides in the golgi apparatus. This newly discovered difference in sub-cellular trafficking between normal and lung cancer cells could potentially be used as an effective strategy in targeted intracellular delivery, especially targeting golgi-resident enzymes for possible treatment of diseases associated with glycans and glycoproteins, such as, congenital disease of glycosylation(CDG). This very important detail in intracellular trafficking inside normal and cancer cells is an indispensable part in nanoparticle-based intracellular drug delivery. 展开更多

Objective:To investigate if the protective effect ofα-tocopherol against the impact of ethanol on brain morphogenesis involved the activity of the selenoproteins phospholipid hydroperoxide glutathione peroxidase (PHGPx;GPx4) and selenoprotein P (SelPP) that have roles against oxidative stress.Methods:Forty female mice were randomly assigned into natural control (CON), positive control (ETOH), low-, medium-, and high-α-tocopherol-supplemented-ethanol groups (LTOC, MTOC, HTOC, respectively). CON received drinking water without ethanol while ETOH, LTOC, MTOC and HTOC groups received 20% ethanol in drinking water. The supplemented groups were given respective dosages ofα-tocopherol, 0.410, 0.819, and 1.640 mg/g body weight, at day 14 before mating onwards to the day 9 of gestation. At 10.5 ED of gestation (1100 h), the pregnant females were sacrificed by cervical dislocation and the embryos were harvested. Total RNA were extracted, cDNA synthesis and qRT- PCR analyses were carried out.Results: The level of expression of PHGPx in the positive control was significantly lower than that of the natural control. Among the threeα-tocopherol-supplemented groups, only the medium dose- group was significantly higher than the positive control. The level of expression of SelPP in the positive control was significantly lower than those of the natural control, the low- and medium- dose -tocopherol supplemented groups. In the high dose-α-tocopherol supplemented group, the level of expression was not significantly different from the positive control but significantly lower than the natural control.Conclusions: The activity of the selenoproteins PHGPx and SelPP are involved in the internetwork of antioxidative enzymes with vitamin E when given up to a medium dose only and is one of the possible pathways of shielding embryonic development against the impact of ethanol on brain morphogenesis. This study strengthens the impact of dietaryα-tocopherol and Selenium supplement during the critical period of pregnancy. 展开更多

BACKGROUND Colorectal cancer(CRC)ranks third in terms of incidence and second in mortality worldwide.In CRC,the silencing of mismatch repair genes,including the mutL homolog 1(hMLH1)has been linked to microsatellite instability(MSI),the lengthening or shortening of microsatellite repeats.Very limited data have been presented so far on the link of hMLH1 methylation and MSI in Southeast Asia populations with sporadic CRC,and on its clinical significance.AIM To investigate the significance of the MSI status and hMLH1 methylation in CRC Filipino patients.METHODS Fifty-four sporadic CRC patients with complete clinical data were included in this study.Genomic DNA from CRC tumor biopsies and their normal tissue counterparts were profiled for MSI by high resolution melting(HRM)analysis using the Bethesda Panel of Markers(BAT25,BAT26,D2S123,D5S346,and D17S250).hMLH1 methylation screening was performed using bisulfite conversion and methylation specific polymerase chain reaction.Statistical analysis was conducted to calculate their associations to clinicopathological characteristics and survival relevance(Kaplan-Meier curves and the log-rank test).RESULTS hMLH1 methylation was observed in 9%and 35%of CRC and normal samples,respectively.Higher incidence of consistently methylated hMLH1 found in both normal and CRC was noticed for relation to location of tumor(P<0.05).As for MSI status,D2S123 the most common unstable microsatellite and MSI-high(MSIH)was the most common MSI profile,counted for 46%and 50%of normal and CRC tissues,respectively.The presence of MSI-low(MSI-L)and microsatellite stable(MSS)was 43%and 11%for normal,and 31%and 19%for CRC samples.The mean month of patients’survival was shorter in patients whose normal and tumor tissues had methylated compared to those with unmethylated hMLH1 and with MSI-H compared to those with MSI-L/MSS(P<0.05).This was supported by significant difference in Kaplan-Meier with log-rank analysis.This data indicated that hMLH1 methylation and high MSI status have prognostic value.CONCLUSION This study showed the clinical significance of hMLH1 methylation and MSI status in sporadic CRC Filipino patients,especially in the normal part of the tumor. 展开更多

Socially-responsible business and ethical behavior of companies have been of interest to academia and practice for decades, but the focus has almost exclusively been on large corporations, while small and medium-sized enterprises (SMEs) have not received as much attention (Hammann, et al., 2009). Worthington, et al (2006) recognized the need to encourage socially-responsible business practices among the 90 per cent or more of the world's businesses that are classified as SMEs. Perrini, et al (2007) found that size explains the differences in firms' willingness to define and implement such specific corporate social responsibility (CSR) strategies, while Murillo and Lozano (2006) concluded that it still remains to be explored whether manufacturing companies tend to apply CSR more extensively, or whether businesses oriented to other business have a tendency to incorporate CSR into their management patterns to a higher degree. Moreover, President Gloria Macapagal-Arroyo, in her 7 June, 2002 speech, recognized the importance of Chinese-Filipinos in helping improve the Philippine economy, and yet, not much research had been done on this sub-sector. Thus, this paper focuses on the effect of finn size and finn activities on the social responsibility practices of selected 30 micro, small and medium-sized enterprises (MSMEs) in Metro Manila which are owned by Chinese-Filipinos. Survey questionnaires and interview were used for gathering data, while a correlations test was used to analyze the data and to conclude whether finn size and finn activities have an effect on the sampled companies' CSR practices. 展开更多

The present study was conducted primarily,to determine the diversity of basidiomycetous fungi and their taxonomy,in the northeastern side of Quezon Protected Landscape,bordering the municipalities of Pagbilao,Padre Burgos and Atimonan in Quezon province,Southern Philippines.Ten quadrats measuring 10 m×15 m with an interval of 50 m were established from a transect line set up from the baseline to the peak of the landscape.Species of basidiomycetous fungi were pre-identified in the field.Substratum,form,texture,size,color and other noteworthy characteristics were recorded during the time of collection.Confirmation of identities was done using published textbooks,literature and consultation with mycology expert.A total of 863 individuals of basidiomycetous fungi were collected and identified belonging to 19 different families,31 genera and 53 species.Polyporaceae family has the highest number of species representing 30%of the total number of individuals documented.Most of the species belong to Hexagonia and Polyporus genera.The current research revealed that most of the substrates used by these fungal organisms are woody substrate,specifically rotten woods.The results of Shannon-Wiener diversity index showed that the area has a high basidiomycetous fungal diversity.There was also a high species richness of these fungal organisms,but there was a low dominance and the species were not evenly distributed in the area.As this area is open for hikers,it is recommended that a continuous monitoring of the macrofungi community be done for sustainability and conservation. 展开更多

Changes in seaweed biodiversity reflect ecological changes and management of coastal communities.Calatagan Bay is a tourism,agriculture and aquaculture hotspot fronting the Verde Island Passage,touted to be the global center of marine biodiversity.Detection of stressors through monitoring is the key in the proper management of the area.This study surveyed existing seaweed species of the coast,and contrasted it with reported species in the area together with fluctuations in sea surface temperatures for the past two decades,contrasted with the local knowledge and perspectives of local coast-dwellers.Seaweed along the coast were collected from a representative area of 50 km^2 with species identification based on morphology and pigment.Ten species that were previously unreported were found while fourteen previously reported species were no longer observed.Caulerpa,Kappaphycus and Sargassum,all with known market demands,were the dominant genera.Sea surface temperature data from local weather stations and the NOMADs database indicate significant warming events from June 1998 to present,with peak sea surface temperature at 31.9oC.Focused group discussions with local communities indicate increased incidences of ice-ice disease,and issues with the uncontrolled use of fertilizers of neighboring farms contaminating their coastal fronts. 展开更多
