Integrating machine learning and blockchain: Conceptual frameworks for real-time fraud detection and prevention
Authors: Halima Oluwabunmi Bello  , Courage Idemudia  , Toluwalase Vanessa Iyelolu
Published: July 2024

Integrating machine learning (ML) and blockchain technologies presents a groundbreaking approach to real-time fraud detection and prevention, addressing the growing complexity and sophistication of financial fraud schemes. This integration leverages the strengths of both technologies: the predictive power of ML algorithms and the transparency, security, and immutability of blockchain. Machine learning algorithms are proficient at analyzing large datasets, detecting patterns, and identifying anomalies that signify potential fraud. By employing supervised learning models such as logistic regression, decision trees, and neural networks, financial institutions can classify transactions and predict fraudulent activities with high accuracy. Unsupervised learning techniques, such as clustering and anomaly detection, are instrumental in discovering new fraud patterns without the need for labeled data, thus enhancing the detection of novel fraudulent behaviors. Blockchain technology, on the other hand, provides a decentralized and tamper-proof ledger that ensures data integrity and traceability. Transactions recorded on a blockchain are immutable and transparent, allowing for real-time monitoring and auditing. Smart contracts, self-executing contracts with the terms directly written into code, can be programmed to trigger alerts or actions when suspicious transactions are detected, further automating the fraud prevention process. The conceptual framework for integrating ML and blockchain involves several key components. First, data from financial transactions are continuously collected and stored on a blockchain, ensuring transparency and security. ML algorithms analyze this data in real time, identifying suspicious patterns and flagging potential fraud. When a potential fraud is detected, a smart contract is executed, which can instantly block the transaction, alert the relevant authorities, or initiate further verification processes. This integrated approach addresses several challenges in traditional fraud detection systems. The decentralized nature of blockchain eliminates single points of failure and reduces the risk of data tampering. The transparency of blockchain enhances the trustworthiness of the detection process, while the predictive capabilities of ML provide high accuracy and adaptability to new fraud tactics. Additionally, the real-time processing capabilities of both technologies ensure prompt detection and prevention of fraudulent activities. In conclusion, the integration of machine learning and blockchain offers a robust framework for real-time fraud detection and prevention. This synergy not only enhances the security and reliability of financial transactions but also paves the way for more advanced and automated compliance systems, ultimately strengthening the financial ecosystem against fraudulent threats.

Authors: Breno Bitencourt Brás  , Gabriel Toledo  , Sérgio Murta Maciel
Published: July 2024

Introduction: The anatomical study cannot be limited to memorization and identification of structures. It is essential that, in a modern and dynamic approach to this discipline, contextualization is adopted, and above all, the clinical applications of what is studied, in addition to other methods such as 3D images. It is necessary to understand the student's conception of such methods – the didactic and scientific evidence at the moment – so that they can make the connection – in the present and the future – with professional life. Methodology: The research, carried out with 163 medical students from two educational institutions in Juiz de Fora, aimed to find out which methodologies were used in their anatomy course; Which one(s) among them is(are) seen as the most effective, and most facilitator(s) of the learning process and approach to clinical practice. The data obtained were processed using the SPSS program, version 20.0. Results: It was evident that the approach to anatomical content based on clinical direction, contextualization of the subject, and use of radiological images is more widespread in Medicine. The application of seminars and clinical debates was scarcely explored. The use of alternative technologies to slides was notable in the Medicine course. Medical students, markedly, advocate for contextualizations and clinical applications. Conclusions: Students, in general, recognize the effectiveness of contextualization, clinical correlations, and the use of images. Few students support the use of seminars. As much as the interviewees do not prefer more summarized theoretical classes, they would like fewer structures to lean about, with more direct books.

This study examines the utilization of rice husk ash (RHA) and slaked lime as substitutes for a portion of the cement in manufacturing concrete. The RHA was acquired from a nearby source, subjected to calcination at temperatures ranging from 500 to 700 °C, and then passed through a sieve to obtain particles with a size of 150 microns. Concrete mixes were made using Ordinary Portland cement (OPC), fine and coarse aggregates, and water, with different amounts of RHA and slaked lime. The concrete mix design adhered to established standards, with a mix ratio of 1:1.5:3 (cement: fine aggregate: coarse aggregate). The experiment was designed using response surface methods, with RHA, slaked lime, and cement as factors, each having five levels. Concrete cubes were formed using 100 mm steel moulds and then submerged in water to assess their workability. The compressive strength was measured using universal testing equipment after 7, 28, and 90 days of cure. The flexural strength of concrete beams was assessed after 7 and 28 days. Samples were subjected to scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) examination after 28 days. The compressive and flexural strengths increased as the curing period progressed, with the 10% RHA substitution showing the maximum strength. The SEM analysis showed that RHA10 exhibited the maximum concentration of silicon, which corresponds to the recommended 10% replacement level of OPC and meets the concrete specifications specified by ASTM M20 grade. Utilising RHA decreases expenses and minimises the amount of concrete that is discarded. The most effective replacement for OPC was 10% RHA, which produced long-lasting and strong concrete.

Published: July 2024

Heavy metal pollution has become a global problem threatening the health of humans and other living things. It is crucial to monitor the changes in air concentrations and reduce pollution, mainly due to the potential harm of heavy metals taken into the body by inhalation. For these purposes, plants have begun to be used extensively as biomonitors or accumulators. However, since each heavy metal accumulates in different plants at different levels, the appropriate biomonitor or accumulator species for each heavy metal must be determined separately. This study aimed to assess the usability of Cedrus atlantica, grown in Düzce, where heavy metal pollution is at high levels, for monitoring and reducing the change in palladium (Pd) pollution in the air. Within the scope of the study, changes in Pd concentration in Cedrus atlantica stem sections grown in Düzce, which is among the five most polluted cities in Europe, depending on organ, direction, and age range in the last 60 years, were evaluated. As a result, it was determined that Pd pollution in the region has increased significantly in recent years, and traffic density is thought to be effective in this increase. It was also determined that Cedrus atlantica is a highly suitable species for monitoring the changes in Pd pollution and reducing pollution.

ChatGPT, developed by OpenAI, represents a significant advancement in AI technology, particularly noted for its ability to engage in human-like conversations. This review article is about role of ChatGPT in antenatal care during pregnancy and its limitations in addressing health-related issues. While ChatGPT offers accessible and empathetic responses to queries about pregnancy and childbirth, its reliability and accuracy remain concerns. The model's reliance on statistical patterns in data often leads to biased or incomplete information, lacking necessary citations. Despite these limitations, ChatGPT shows promise in supporting clinical decision-making but requires oversight to ensure medical advice is precise and appropriate. Ethical considerations, including privacy and misuse risks, underscore the need for further development and validation in healthcare applications.

Abstract. The 172 street children depicted are in vulnerable, marginal, and exploited conditions in the middle of the urban district of Bandung. To this day, the church as a spiritual institution and a community is still engaged in charitable diocese with a sporadic approach in responding to the street child phenomenon in the city. This research aimed to produce and develop a model of education of Christian character values as a contextual mission service for street children in Bandung City. This research was conducted by the Research and Development (R&D) method with the R2D2 model (Recursive, Reflective, Design, and Development. Through the Contextual Teaching & Learning (CTL) model in the implementation of Christian character education values, street children construct values given and shown in positive and beneficial actions and behaviors for empowerment. The church is expected to be able to build a positive image as a missionary who not only focuses on charitable diocese, but also meets the basic needs of street children through the implementation of a model of education of Christian character values.Abstrak. Sebanyak 172 anak jalanan digambarkan berada pada kondisi rentan, marginal, dan tereksploitasi di tengah perkotaan Bandung. Hingga saat ini gereja sebagai lembaga rohani, sekaligus komunitas, masih berkutat dengan diakonia karitatif dengan pendekatan sporadis dalam merespons fenomena anak jalanan di perkotaan. Penelitian ini bertujuan untuk menghasilkan dan mengembangkan produk berupa model pendidikan nilai karakter Kristiani sebagai pelayanan misi kontekstual bagi anak jalanan di Kota Bandung. Metode yang digunakan dalam penelitian ini adalah metode Research and Development (R&D) dengan model R2D2 (Recursive, Reflective, Design, and Development). Melalui model Contextual Teaching & Learning (CTL) dalam implementasi pendidikan nilai karakter Kristiani, anak jalanan mengonstruksi nilai yang diberikan dan ditunjukkan dalam tindakan dan tingkah laku positif dan bermanfaat untuk pemberdayaan dirinya. Gereja diharapkan mampu membangun citra positif sebagai pelaku misi yang tidak hanya bertumpu pada diakonia karitatif, akan tetapi memenuhi kebutuhan dasar anak jalanan melalui implementasi model pendidikan nilai karakter Kristiani.

Moda transportasi KRL Commuter Line menjadi salah satu transportasi publik yang jumlah penumpangnya mengalami kenaikan secara signifikan selama periode Januari – Maret 2023, sehingga terjadi penumpukan penumpang dan berdesakan di peron stasiun Manggarai saat jam sibuk. Salah satu penyebabnya adanya pembangunan stasiun Manggarai yang akan dijadikan sebagai stasiun sentral, sehingga membuat PT KCI harus menata ulang rute perjalanan kereta dan menjadikan banyaknya pengguna yang melakukan pindah peron di stasiun Manggarai. Kualitas pelayanan pada stasiun perlu dievaluasi dan diperbaiki jika masih belum memenuhi harapan, agar memberikan rasa nyaman dan aman pada pengguna. Penelitian dimulai dengan penyebaran kuesioner Servqual  dan Kano kepada 100 responden sesuai kriteria, kemudian diintegrasikan dan dianalisis menggunakan metode Gap 5 dan Kano dengan bantuan SPSS 23.0. Hasil integrasi metode tersebut kemudian diterapkan kedalam metode QFD (Quality Function Deployment). Pengolahan kedua metode tersebut menunjukkan dari 31 atribut pertanya­an yang diajukan kepada pengguna, terdapat 14 atribut yang dijadikan Customer Require­ment untuk selanjutnya dirancang perbaikan kualitas pelayanannya menggunakan HOQ (House of Quality). Technical Requirements yang dijadikan sebagai prioritas perbaikan adalah membuka eskalator/ tangga yang ditutup dengan nilai technical response 15%, sosialisasi SOP 13%, standarisasi waktu pelayanan 13%, dan standarisasi waktu pela­ya­nan 10%. Penelitian menunjukkan informasi faktor-faktor yang menjadi pengaruh kualitas pelayanan di stasiun Manggarai dan dapat dijadikan sebagai benchmarking kualitas pelayanan dengan stasiun lainnya, karena dengan peningkatan kualitas pelayanan dapat membangun reputasi yang baik dan citra yang positif bagi penumpang.

Produk mudah rusak memiliki karakteristik cepat kadaluarsa atau rusak serta kehilangan kualitas karena faktor eksternal seperti kelembaban, suhu, atau tekanan atmosfer. produk unggas beserta turunannya termasuk barang mudah rusak. CV Sinar Pangan Mandiri (SPM) merupakan perusahaan kelas menengah yang bergerak di bidang peternakan broiler, ayam petelur (layer farm), dan ayam pejantan.  Permasalahan yang terjadi pada CV Sinar Pangan Mandiri yaitu kompleksnya jaringan distribusi serta tidak meratanya pembagian jumlah agen yang dilayani setiap Truk. Akibatnya beberapa Truk terlalu padat jumlah muatannya. Akhirnya keterlambatan pengiriman produk, dan terjadinya susut bobot unggas yang didistribusikan dikarenakan unggas mengalami stres selama perjalanan distribusi tidak dapat dihindari. Penelitian ini bertujuan untuk meminimasi biaya pengiriman, serta membagi jumlah muatan untuk setiap Truk supaya lebih merata pada saat mengangkut produk unggas. Metode yang digunakan yaitu VRP berbasis Geographic Information System (GIS). Penelitian ini menggabungkan tiga jenis Vehicle routing problem (VRP) capacitated VRP, VRP with time windows, dan VRP with pick-up delivery, (CVRPTWPD) menggunakan Network Analyst VRP pada software ArcGIS yang meng­gunakan pendekatan Dijkstra dalam penentuan rute optimal. Hasil penelitian menunjuk­kan bahwa rute usulan mampu mengurangi waktu tempuh total sebanyak 163 menit (2,71 jam) dan jarak tempuh total sebesar 77,85 km, yang berarti penurunan waktu tempuh sebesar 10% dan penurunan jarak tempuh sebesar 37% dibandingkan dengan rute distribusi awal. Selain itu pembagian agen untuk setiap kendaraan menjadi lebih merata. Penelitian ini mendukung studi sebelumnya bahwa penggunaan VRP berbasis GIS dapat menghasilkan rute distribusi yang lebih optimal dengan menggabungkan tiga jenis VRP: capacitated VRP, VRP with time windows, dan VRP with pick-up delivery. Namun, penelitian ini belum mempertimbangkan kondisi kepadatan jalan raya secara real-time dan total waktu pengiriman. Untuk penelitian selanjutnya, disarankan mempertim­bang­kan faktor-faktor tersebut dan mengeksplorasi metode lain untuk menyelesaikan permasalah­an VRP dengan lebih cepat dan efisien.
