http://ijaems.com/ Open Access international Journal to publish research paper en-us September Clustering is one of the important techniques in data mining. It is an unsupervised task of grouping similar data. It has been applied in various fields with high degree of success. This study aimed to determine the learner segments based on readiness to online learning modality using K-means algorithm. A dataset was collected, tabulated and pre-processed. Further, the values were scaled and transformed using t-distributed Stochastic Neighbor Embedding. Using elbow method and determining the silhouette score, the best K value was determined. Then clustering was conducted using the selected number of clusters. Results revealed three groups of learners; Moderate-signal mobile users, Low-signal mobile users, and mixed group of Low/moderate-signal mobile/broadband users. Students from the different clusters are more suited for flexible learning as opposed to online learning. Varied learning modalities can be catered for students from the different learner segments. Formulation and adoption of new policies are needed to offset the effect of the pandemic towards the students. http://ijaems.com/detail/clustering-of-learners-based-on-readiness-to-online-modality-using-k-means-algorithm/ Daryl B.

AL-Qassim region, Saudi Arabia, is facing enormous challenges in dealing with pavement networks because the current pavement management system is not capable to maintain the pavement network at desirable condition, leading them to taking improper decisions regarding maintenance and rehabilitation activities. Therefore, it is important to maintain the current roads at an acceptable level of service by coordinating the maintenance works and evaluating the pavement condition periodically to reduce the deterioration rate. The goal of this paper is to review the practiced PMS and study how it can be implemented in Al-Qassim roads with some adjustments. The proposed PMS will assist the decision-makers in Al-Qassim municipality in planning the maintenance and rehabilitation works during the roads design life. http://ijaems.com/detail/a-review-of-pms-systems-and-how-can-be-implemented-in-al-qassim-municipality-roads/ Fawaz Alharbi http://ijaems.com/upload_images/issue_files/2IJAEMS-10820217-AReview.pdf This study aimed to identify, analyze and determine the level of self-efficacy and self-esteem of B.S. Information Technology (BSIT) students of a higher learning institution in Nueva Ecija, Philippines. It was conducted during the 1st Semester of the academic year 2019-2020. This research utilized descriptive approach to describe the level of self-esteem and self-efficacy of the students and to draw valuable insights that may contribute to the improvement of the teaching and learning practices of the faculty members in the college. The researchers used random sampling to ensure that all year levels are well represented in the study. There were 285 students who voluntarily responded after the researchers explained to them the purpose of this study. Responses were tallied, summarized and interpreted. Results show that the level of self-esteem and self-efficacy of the students were moderate/medium (WM=2.03, WM=2.08). This indicates that depending on the given situation or context, students may increase or decrease the level of their self-esteem and self-efficacy. This study suggest that students may be exposed to more activities that may help them improve their self-esteem and self-efficacy to greatly contribute to their holistic development. Future studies may be conducted to a larger number of respondents and to understand the link between self-efficacy and self-esteem on their academic performance, drop-out rates, and retention rates. http://ijaems.com/detail/an-inquiry-on-the-self-esteem-and-self-efficacy-level-of-information-technology-students/ Ruth G.

Olipas http://ijaems.com/upload_images/issue_files/3IJAEMS-10920213-AnInquiry.pdf The Philippines adapted the K+12 program to uplift its educational standards in order to become comparable to those of other countries. RA 10533 was enacted and mandated that all schools both public and private must comply with its provisions/guidelines to better equip its citizens with the necessary knowledge and skills to meet the higher educational demands of life and work of the 21st century. This study assessed the curriculum, instruction, challenges, adjustments, and compliance to the standard of the K+12 program implementation of teachers together with their principal/school heads in the Laboratory High School of Nueva Ecija University of Science and Technology, during the academic year 2019-2020. The study utilized the descriptive method in order to describe the current status of the K+12 curriculum implementation in the said school. A total of 69 respondents were selected through purposive sampling coming from the four campuses of NEUST namely Gabaldon Campus, San Isidro Campus, Fort Magsaysay campus and General Tinio Campus. Weighted means were used to analyze their assessment of the curriculum, instructional-related factors and the challenges and adjustments encountered. The findings showed that the curriculum content, objectives and instructional-related factors are in conformity with the standards, policies or guidelines set by RA 10533, or otherwise known as “Enhanced Basic Education Act of 2013”, subject to some improvements due to the addition of elective subjects. Respondents consider their learners as the center of the educational process, use varied types of teaching strategies and techniques depending upon the learners need, and has individual, paired or group applications. Resource materials and facilities are available but they are not adequate, nonetheless, school environment is generally conducive to learning. No significant relationship exists on their assessments with respect to the challenges experienced and the adjustments made in the implementation of the K+12 curriculum. http://ijaems.com/detail/challenges-and-adjustments-in-the-curriculum-and-instruction-of-the-k-12-program-basis-for-strategic-plan/ Dr. Gerald A. Quijano http://ijaems.com/upload_images/issue_files/4IJAEMS-10920211-Challenges.pdf The purpose of this study was to investigate the influence of information technology on tax administration in the Kurdistan. The impact of information technology on tax productivity as well as the link between information technology on tax implementation and tax planning were especially studied in this study. In this study, a descriptive research approach was adopted, with a questionnaire being used to collect data, which was then analyzed using multiple regression and Pearson product moment correlation. The findings of the study revealed that information technology (online tax filing, online tax registration and online tax remittance) has a positive impact on efficient tax management. http://ijaems.com/detail/analysis-the-impact-of-information-technology-on-efficient-tax-management/ Pshdar Abdalla Hamza, Khowanas Saeed Qader, Bayar Gardi, Hawkar Anwar Hamad, Dr. Govand Anwar http://ijaems.com/upload_images/issue_files/5JAEMS-11020218-Analysisthe.pdf
