The purpose of this study is to determine which airlines Davao City-bound and outbound passengers prefer. Passenger information was acquired via survey questionnaires employing the Likert scale. In this study, non-experimental quantitative research employing a casual research method was employed. Using descriptive and informal research methodologies, this study investigated whether demographic variables and airline service quality influence the airline service choices of Davao City passengers. This investigation employs artificial neural network research to determine which factors influence airline preference. The majority of air carrier respondents are between the ages of 21 and 35, are predominantly female, and are employed by private companies. The airline preferences of passengers are influenced by price, cabin services, flight schedule, safety, on-time performance, and employee conduct. Important airline demographics included age, occupation, and sex. Price is the most significant criterion when selecting an airline, followed by flight schedule, on-time performance, and employee conduct. Flights should offer discounts to students and senior citizens. They may adjust fares based on the findings. To attract a broader age range of customers, airlines should strategically organize their marketing and focus on specific market niches. To increase sales, airlines may consider offering discounted, low-cost, or one-peso fares during certain times. To assist time-sensitive travelers in reaching their destinations in the event of airline delays or cancellations, alternative flights are advised. To gain a deeper understanding of airline carrier selection, research should be extended, employing a larger sample or alternative statistical methods. This study employs a non-experimental quantitative approach and artificial neural networks to analyze how demographic factors and service quality metrics specifically identifying price and scheduling as the most critical drivers influence the airline preferences of travelers in Davao City. 2023-02-05T00:00:00Z https://repository.umindanao.edu.ph/handle/123456789/2325 Predictive soil-crop suitability pattern extraction using machine learning algorithms Soberano, Kristine T.; Pisueña, Jeffric S.; Tee, Shara Mae R.; Arroyo, Jan Carlo T.; Delima, Allemar Jhone P. Machine learning has experienced notable advancements in recent times. Furthermore, this field facilitates the automation of human evaluation and processing, leading to a reduced demand for manual labor. This research paper employs data mining techniques and Knowledge Discovery in Databases (KDD) to conduct an evaluation and classification of various algorithms for pattern extraction and soil suitability prediction. The study utilizes experimental data, data transformation, and pattern extraction techniques on diverse soil samples obtained from different regions of Negros Occidental, Philippines. Specifically, the Naive Bayes, Deep Learning, Decision Tree, and Random Forest algorithms are selected for the classification and prediction of soil suitability based on the available datasets. The assessment of soil-crop suitability is based on data sourced from the Philippine Rice Research Institute, considering 14 parameters including inherent fertility, soil pH, organic matter, phosphorus, potassium, nutrient retention (CEC), base saturation, salinity hazard, water retention, drainage, permeability, stoniness, root depth, and erosion. The findings indicate that the Random Forest algorithm achieved the highest accuracy rate at 94.6% and the lowest classification error rate at 5.4%, suggesting a high level of confidence in the model's predictions. The model's predictions reveal that most soil samples in the area are only marginally suitable for banana, maize, and papaya crops. Furthermore, the study demonstrates that the majority of soil samples have a low fertility rating, which significantly impacts crop suitability. The information obtained from this study can serve as a basis for local farmers to develop improved soil management programs aimed at ensuring more productive soil. Simultaneously, it can contribute to active soil protection initiatives addressing issues such as acidity and salinity in Negros Occidental, Philippines. This research paper investigates the use of machine learning algorithms, specifically identifying Random Forest as the most effective, to analyze soil data from various regions in the Philippines and predict its suitability for crops like banana, maize, and papaya. 2023-04-04T00:00:00Z https://repository.umindanao.edu.ph/handle/123456789/2318 Stomach content analyses of lizard species from Mindanao island, Philippines Camino, Fritzie A.; Parba, Faith Jane; Tagoon, Marian Dara; Susulan, Treaseur B.; Vitor, Karyn Chrislene A.; Delima-Baron, Elsa May The Philippines is home to 209 lizard species (Uetz et al. 2021), of which 74% are endemic (Brown et al. 2013a). Knowledge of lizard species in the country has been focused mainlyon species accounts in various localities from Luzon (Diesmos et al. 2004, Devan-Song and Brown 2012, Siler et al. 2012, Brown et al. 2013b, Binaday et al. 2017, Cruz et al. 2018); Visayas (Denzer et al. 1994, Ferner et al. 2000, Bucol et al. 2011, Supsup et al. 2016, Obeña et al. 2021); and Mindanao (Delima et al. 2007, Nuñeza et al. 2010, Beukema 2011, Supsup et al. 2017, Venturina et al. 2020, Pitogo et al. 2021, Solania et al. 2021). Data on the diet of lizards from the country remain limited (Villadolid 1934, Reyes 1957, Auffenberg and Auffenberg 1988, Struck et al. 2002, Bucol et al. 2011, Law et al. 2018, Tabug et al. 2018). Information on diets from earlier reports used field observations (Bucol et al. 2011, Bennett 2014), claw material subjected to isotope analysis (Struck et al. 2002), individual tracing, and fecal sample examination (Law et al. 2018), in addition to inspection of stomach contents from captured wild specimens prior to preservation (Tabug et al. 2018) and stomach content analysis of preserved specimens (Villadolid 1934, Auffenberg and Auffenberg 1988). This study addresses the limited data on Philippine herpetofauna by analyzing the stomach contents of lizard species from Mindanao to provide essential insights into their dietary habits and ecological roles. 2023-06-01T00:00:00Z https://repository.umindanao.edu.ph/handle/123456789/2312 “Kolori, Sirkuli”: semantic relations of the indigenized English lexemes in Cebuano Talde, D.K.J.R.C; Lovitos, A.H.R This study investigated the use of indigenized English lexemes (IELs) in Cebuano, specifically focusing on the Mother Tongue-Based Multilingual Language Education (MTB-MLE) Sinugbuanong Binisaya textbooks. These IELs have been prevalent despite the existence of the equivalent words and language policy being enforced. Specifically, this study sought to: identify the linguistic features of the IELs; determine the semantic relations associated with the IELs; and explore how Cebuano IELs reflect the cultural norms of its users. A qualitative research design was employed, utilizing textual analysis and thematic analysis. The findings reveal notable phonological and morphological features in the IELs. Phonologically, insertion, deletion, and substitution processes were observed, while morphologically, changes in the inflectional affixes of verbs were highlighted, specifically through the use of the common affixes gi, i-, -i, and nag-. Furthermore, the IELs exhibit various semantic relations that include contrasts, similarities, class inclusion, case relations, and part-whole relationships. Finally, emergent themes demonstrate how IELs in Cebuano reflect the cultural norms of its users, encompassing preferences in teaching styles, classroom observations involving IELs, teaching goals and intentions, thoughts and attitudes, and challenges encountered with the MTB-MLE program. The study concludes that language borrowing offers functional advantages and remains essential even in the teaching of a mother tongue such as Cebuano. Future studies could explore IELs in informal contexts such as magazines, advertisements, and social media, investigate the semantic changes of IELs in Cebuano, and conduct longitudinal studies on the effects of the MTB-MLE program on its learners. This study analyzes the linguistic features and semantic relations of English loanwords in Cebuano MTB-MLE textbooks, concluding that these indigenized lexemes serve essential functional roles and reflect the cultural norms and pedagogical attitudes of their users. 2023-06-23T00:00:00Z
