Design and Development of a Comprehensive, Robust and KM-Scalable Database (Backend) for a PILI (Canarium ovatum Engl.) Information System
No full textThis paper presents the results of efforts to design and develop a comprehensive repository of knowledge for Pili (Canarium ovatum Engl.), an endemic crop in the Bicol Region known for its various uses. This study, in general, responds to the challenges entailed in the national government’s having identified “PILI” as the flagship commodity of the Bicol region. In particular, it seeks to address the dearth of accessible knowledge on the Pili industry. Enabling users around the world to become acquainted with this endemic crop. The database’s initial goal is to provide key facts on population dynamics of Pili crop (Canarium ovatum Engl.) varieties and is designed and structured towards knowledge management (KM) buildup.
Many similar information systems applied in agriculture were consulted and visited by the researchers in the literature such as the International Rice Research Institute (IRRI’s) comprehensive crop information system [1], and the more recent Mango Resource Information System [2] which was developed for the management of the phenotypic, genetic, molecular to chemical and other information on mango cultivars.
The breadth and depth of information in the database are designed to cater to the different needs of diverse groups of stakeholders (farmers, vendors, processors, scientists, researchers, policy-makers, teachers, and students). Its various applications range from basic Pili bio-ecological data management to e-commerce and analytics. This Pili database covers the more than 14 NSIC (National Seed Industry Council) accredited pili varieties, 200 accessions compiled from more than 150 references in partnership with more than 10 collaborators, and more than 500 pictures taken from different cultivars in the Bicol region.
At present, the database has 180 tables, enriched by the collection of various Pili related information ranging from its nomenclature, accession, NSIC registration, distribution, morphological characteristics, genetic resources, geo-mapping and characterization, propagation techniques, emerging diseases, growth and yield response, postharvest processing, to products, e-commerce, data analytics and other related data present in different cultivars. The database is normalized to handle complex queries needed to generate knowledge not only for Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (PCAARRD) and its member-agencies but for Pili farmers/producers, vendors, enthusiasts, retail outlets, and the market as a whole. It is designed with flexibility in mind to interface and interconnect/link with other PCAARRD systems for a dynamic web of knowledge. It is believed that making information and data on Pili publicly available will enliven and invigorate the stakeholders in this industry and help boost yield/production, encourage more research and development efforts, promote innovation, step up marketability of various pili-related products, and consequently improve the living conditions of marginalized farmers and vendors
Modified Vigenere Cryptosystem Using Matrix Manipulation and Base94 Encoding Scheme
No full textSecurity in the field of Information Technology is the defense of digital information along with its assets against internal and/or external malicious and accidental threats. To secure such valuable information, cryptography is used. A cryptography or encryption algorithm is the process of transforming sensitive data into confounding data in such a way that the person or the machine with a key can decode the hidden information. Among these algorithms is the Vigenere matrix. In this article, a hybrid approach is used in the encryption algorithm. This approach implements the matrix manipulation principle and Base94 encoding algorithm. In order to measure the performance of the proposed algorithm, the Avalanche Effect is used. The result of the study shows a significant high avalanche effect compared to the traditional Vigenere cryptosystem
Internet Diffusion Rate among ASEAN Countries
No full textThis paper examines the rate of Internet diffusion among the Association of Southeast Asian Nations (ASEAN) countries during the period 2001-2018. The Bass diffusion model was used to estimate the total number of potential adopters, the coefficient of innovation, and the coefficient of imitation. This paper uses the International Telecommunication Union (ITU) 2001-2018 dataset to study the rate of Internet diffusion. The results show that Internet diffusion among ASEAN countries was characterized by different S-shaped curves of the diffusion process. The estimated diffusion curves provide evidence that high-income countries in the ASEAN have higher diffusion rate as compared to the lower-income countries. Further, the study found that the country that has the highest rate in the point of inflection is also the country that has the lowest rate of Internet diffusion. The results also indicate that among the 10 members of the ASEAN countries, four of which have reached their peak of adoption before 2018, and two of which have reached the saturation point of the diffusion process, and one of which is continuously dominating since the launch of Internet up to the present while the rests are closely following the path made by high-income countries
Developing “Genesis” Instructional Material in Learning the Different Theories on the Origin of Life
Get PDFThe utilization of technologies in learning has been exercised by educators in order to make classroom discussions more engaging and enhance learning among students. In this regard, developing instructional materials that integrate technologies on the different sets of learning tasks is essentially important. This paper deals with the development of an instructional material called “Genesis” in learning the theories on the origin of life and Biology unifying theories. This instructional material was developed to capture the student’s 21st century learning skills in Biology

This study aims to match two text files and get their average rate of accuracy. A file comparison prototype has been developed to perform the match, and its accuracy was determined with regards to the number of files and their sizes. The prototype’s acceptability will be determined with regards to usability, performance, and design. The arithmetic mean will be used to determine the accuracy of the matching text file, and the prototype will display the matched and unmatched results. The results show that the acceptability level for matching two text files is accurate, and the design of the GUI is easy to learn and use.
A Study of a Local Search Engine for Desktop PCs using an Enhanced Boyer-Moore Algorithm
No full textThe volume of digital information and documents stored on desktop computers and over the Internet has been rapidly increasing in the past few years. Thus, search algorithms, methods, and programs are becoming popular to help in finding the intended information or files. This study proposes a string-matching algorithm to improve the pattern-matching technique of the traditional Boyer-Moore (BM) search algorithm. The proposed enhanced BM algorithm simultaneously scans the text from both sides (left and right) using two windows wherein each window has a size that is equal to the pattern length
