Modelling and Verification of Multi-agent Hybrid Systems
Authors: Das Sarthak
Published: August 2024

Multi-agent hybrid systems are widely seen in applications such as highly autonomous vehicles, robotics and telecommunication networks, distributed real-time systems, distributed artificial intelligence, surveillance systems, industrial control systems, power systems and smartgrids, coordinated defence systems, and healthcare. Multi-agent hybrid systems are often safety-critical, where ensuring the operational correctness is absolutely necessary. Examples of safety-critical multi-agent hybrid systems are autonomous vehicles, systems in healthcare such as insulin infusion pumps, and so on. Due to this safety-critical nature, the formal verification of multi-agent hybrid systems becomes necessary to ensure their correctness and integrity. In this work, we study the mathematical modelling of such systems by hybrid automaton and by the parallel composition of hybrid automata. Subsequently, we study the usage of model-checking tools for multi-agent hybrid systems, particularly Verse and SpaceEx, for their simulation and verification. We then address two exercises in modelling of multi-agent hybrid systems. Firstly, we propose two hybrid models to achieve clock synchronization in swarm robotic systems via pulse coupling, verify whether a global synchronization is at all achieved, and compare it with existing models in literature. Secondly, we model Dijkstra's $k$-state solution to the self-stabilizing token ring problem as a multi-agent hybrid system and prove its convergence for a specific case using formal verification techniques. Then, we study the model checking via reachability analysis approach to formal verification of multi-agent hybrid systems, and propose a path-oriented reachability analysis algorithm within the framework of the Verse library.

Authors: Parajuli Krishna Prasad
Published: August 2024

The growing use of smartphones in daily communications has emerged as a dynamic device in terms of storing information, searching online materials, and disseminating ideas. The technology has the potential to enhance teachers’ instructional activities. This study presents an analysis of secondary teachers' use of smartphones in their professional development. Twelve teachers were purposely selected to participate in this case study. The data collected through the semi-structured interviews and participant observation were thematically analysed. The study found that although teachers were not compelled to use digital technology in their professional activities, they used smartphones to update their professional knowledge and skills, monitor their performance, and seek support from other teachers by networking and collaborating . The findings indicate that the use of smartphones in instructional activities did not transform their traditional pedagogies. However, teachers harnessed their smartphones as educational technology for professional development, particularly in learning subject matter and monitoring self performance and problem solving by networking and collaborating with teachers because of the perceived usefulness and ease of use of the technology. Researchers, teacher trainers, teachers, and policymakers need to reconsider the benefits of the educational use of smartphones in teachers' professional development as has given its presence in the personal and professional lives of teachers.

Published: August 2024

Professional development for English language teachers is the process of becoming professionally competent in the classroom and keeping up with the most recent advancements in teaching and learning. In this context, this study explores the factors that influence the secondary level English language teachers’ professional development. Employing the phenomenological research design, four English language teachers were purposively selected from four community schools of Kailali district. Semi-structured interviews and open-ended questions were used as the tools of data collection. The participants were provided open-ended questions to collect information and later on, semi-structured interviews were conducted with each participant for supplementary information. The study reveals that for the professional enhancement of teachers, it is essential to provide sufficient time, resources, chances to attend workshops, equal treatment to all staff, collaboration, support, encouragement, incentive and feedback from administration, peers and students. The findings suggest that since professional development is crucial for improving pedagogical skills and keeping up with current educational trends, English language teachers need institutional, financial, social, and psychological supports.

Neste relato de experiência, socializamos as ações do projeto de extensão intitulado “IFAM-CMC e o resgate da tradição da festa junina, cultura popular e das políticas afirmativas raciais”, iniciado em 2021 e continuado em 2022, desenvolvidas em Manaus-AM, envolvendo 450 participantes. O objetivo geral do PIBEX de 2021 foi socializar o conhecimento técnico sobre fotografia e produção audiovisual, além de divulgar por meio de memorial audiovisual a paisagem arquitetônica da EETI Marquês de Santa Cruz e do bairro São Raimundo. Já o objetivo do PIBEX de 2022 foi sensibilizar a comunidade escolar e acadêmica e sociedade manauara sobre a importância das ações afirmativas étnico-raciais na escola, além de valorizar o folclore popular. Nesse contexto, as ações desenvolvidas demonstraram sua relevância cultural, social e educacional por valorizar essa festa tão popular no Brasil, agregando a tradição dos povos da floresta. E, para evitar a fragmentação que, geralmente, é feita das particularidades pertencentes à pesquisa, à extensão e ao ensino, foi realizada atividade de campo que consistiu em saber quais demandas sociais que o nosso projeto de extensão poderia contribuir para interligar com a comunidade conhecimentos e vivências sobre cultura popular, além da pesquisa bibliográfica e documental. Como resultado, podemos compreender que a extensão é uma forma de influenciar o protagonismo da comunidade escolar e acadêmica, envolvendo os alunos, como sujeitos ativos do processo educativo, no diálogo com a comunidade externa, dessa forma produzindo e reconstruindo conhecimentos, que foram disseminados a partir da produção do memorial audiovisual e do e-book.

Por muito tempo, a merenda escolar não era oferecida para os alunos do Brasil. Mas essa realidade veio mudando com o passar dos anos, sendo percebido que a alimentação dos alunos é parte importante no seu desenvolvimento físico, intelectual e pedagógico. Dessa forma, o governo passou a incentivar programas como o PNAE, que incentiva ações de apoio a regionalização da merenda escolar, através dos CECANEs. No ano de 2021, o CECANE/IFAM foi criado com o apoio do FNDE, que aprovou um plano de trabalho para o ano seguinte, contendo quatro produtos, sendo o terceiro, objeto desse relato, Formação de Merendeiras – enriquecimento nutricional com PANC. Seu principal objetivo foi fomentar a regionalização dos cardápios e a inserção das PANC junto aos profissionais da rede pública de ensino do Estado do Amazonas e do IFAM, responsáveis pela alimentação escolar, as merendeiras e nutricionistas. Como resultado, foram realizados sete cursos no período de novembro de 2022 a janeiro de 2023, alcançando 141 merendeiras e 12 nutricionistas atuantes em escolas públicas da Semed e Seduc dos municípios de Manaus, Careiro da Várzea e Iranduba. A incorporação da aprendizagem das merendeiras, realizando as práticas em suas escolas e nos seus lares, além da troca de experiências com seus colegas que não puderam participar da formação, pôde ser comprovado através de postagens nas redes sociais que elas nos encaminham até hoje.

Published: August 2024

A extensão consiste em um processo educativo, político, social, cultural, científico e tecnológico que possibilita a interação dialógica e transformadora da sociedade. O Plano Nacional de Educação 2014/2024 prevê a garantia de um percentual mínimo de 10% do total de créditos curriculares dos cursos superiores em atividades de extensão. O processo de adaptação dos Projetos Pedagógicos dos Cursos – PPCs - para o cumprimento dessa obrigatoriedade é chamado de curricularização. Este estudo objetivou compreender como a curricularização da extensão está sendo incorporada nos Institutos Federais – IF por meio da análise das produções acadêmico-científicas que relatam essas experiências. Foi realizado um estudo qualitativo, de levantamento do estado do conhecimento, no Repositório da Coordenação de Aperfeiçoamento de Pessoa de Nível Superior (Capes), que identificou e analisou oito publicações que trazem a temática. A maioria dos artigos trata o tema no IF de Santa Catarina, sendo a instituição que mais buscou publicizar suas experiências.  Os trabalhos encontrados trazem duas abordagens: o planejamento do processo de curricularização; e o relato da curricularização já ocorrendo na prática. No primeiro caso, está presente a preocupação com o levantamento diagnóstico das demandas comunitárias e a construção da extensão dialogada com a comunidade. A segunda abordagem mostra as várias possibilidades da inserção da extensão nos PPPs. Destaca-se como desafio o engajamento dos estudantes nas atividades. Em geral, está presente o reconhecimento da importância da extensão para a formação humana.

O presente trabalho tem como objetivo relatar as contribuições de especialistas (Zootecnia e Veterinária) a partir de uma ação extensionista. Nesta ação, foram realizadas palestras sobre a cadeia leiteira para alunos da última série do Ensino Médio. A temática da situação de estudo emergiu do interesse dos alunos, da localidade da escola e da experiência que muitos possuíam com a produção leiteira. Os especialistas apresentaram e construíram cálculos de custo de produção leiteira que consideram diferentes cenários produtivos, variadas maneiras de comercialização, apresentação de parâmetros de qualidade, além de técnicas de análise deste gênero alimentício. Com essa ação extensionista, foi possível contribuir para esclarecer as dúvidas encontradas nessa comunidade escolar e ainda promover novas possibilidades de pensamentos e saberes. Assim, os alunos tiveram a oportunidade de relacionar os conhecimentos curriculares com a solução de problemas presentes no contexto em que vivem. Por fim, esse estudo evidencia a necessidade de intervenções de profissionais especialistas para o desenvolvimento de propostas interdisciplinares no contexto escolar, uma vez que apenas os conhecimentos específicos previstos nos currículos das escolas não permitem que os alunos compreendam a complexidade do mundo que os cerca.

A questão do saneamento básico, intrinsecamente ligada à saúde pública, enfrenta desafios consideráveis no Brasil, especialmente em áreas rurais e comunidades tradicionais. Assim, são relevantes pesquisas e ações que venham contribuir para o preenchimento das lacunas do saneamento dessas regiões. Este estudo buscou avaliar o sistema de abastecimento de água na Comunidade Quilombola Sagrado Coração de Jesus do Lago de Serpa, Itacoatiara/AM, visando à melhoria da saúde coletiva local. A pesquisa foi descritiva e exploratória, com informações de cunho qualiquantitativo, obtidas por entrevistas semiestruturadas, observação direta e coleta e avaliação de amostras de água de consumo, analisados à luz das teorias de cada tema. Visando a conscientização da comunidade sobre as características, importância e boas práticas do saneamento básico, foram realizadas ações de sensibilização e educação ambiental, via realização de encontros e diálogos. Para promover a saúde dos moradores e prevenir problemas relacionados à ingestão de água não potável, foram distribuídos filtros de barro com vela na comunidade. O sistema de abastecimento de água local é deficitário, atendendo somente uma parcela da população, em geral sem tratamento. Análises de água indicam padrões de contaminação sendo consideradas fora do padrão de potabilidade. Vulnerabilidades socioambientais na comunidade ainda persistem com desafios significativos de infraestrutura sanitária, influenciando negativamente a qualidade de vida dessas pessoas. A abordagem mais eficaz para promover mudanças envolve uma combinação de várias estratégias adaptadas a contextos locais, com participação ativa da comunidade, campanhas educativas de sensibilização e conscientização, implementação de tecnologias apropriadas e gestão pública eficaz e atuante.

Este relato de experiência é fruto do desenvolvimento do projeto “Resíduos de frutas amazônicas como matéria-prima para a produção de adubos orgânicos”, financiado pelo Programa de Apoio ao Desenvolvimento de Pesquisa Científica Aplicada à Inovação Tecnológica – PADCIT/IFAM. A proposta valida-se ao considerar que as frutas e frutos do Amazonas têm cada vez mais aceitabilidade no paladar nacional e internacional, crescendo a escala de beneficiamento desses produtos, contudo há a desvantagem de que os resíduos são descartados em grandes quantidades, o que resulta em problemas ambientais e econômicos. Verifica-se, também, o raso conhecimento sobre os benefícios desses subprodutos e sua baixa ou nenhuma aplicabilidade. Este estudo teve o objetivo de utilizar os resíduos de frutas amazônicas como matéria-prima em adubos orgânicos para produção de couve-manteiga (Brassica oleracea) e, assim, disseminar essas técnicas por meio de cartilhas informativas e oficinas sobre fertilidade do solo e adubação orgânica, levando os produtores a uma produção orgânica e sustentável. Concluímos que as práticas educacionais e formativas são necessárias para a difusão de técnicas inovadoras para produção agrícola dos agricultores familiares que,  a médio e longo prazo, constituir-se-ão em futuros produtores orgânicos da região de Coari-Amazonas, voltados para as ações agroecológicas indispensáveis na produção de qualidade, promovendo a sustentabilidade ambiental, diminuindo custos de produção, agregando valor ao produto e promovendo qualidade de vida para a sociedade por meio de alimentos saudáveis.

Published: August 2024

The paper contains proposals for radioactively contaminated concrete structures (RCCS) management, which will be formed, removing fuel-containing materials (FCM) from the Shelter object. RCCS will be characterized by different intensity of radioactive contamination, which is only in the near-surface layer of concrete. In the case of containerized storage of such RW, significant costs will be required, first, for the fragmentation of RCCS in order to convert them into a loose form and for conducting dosimetric and radiometric measurements. A significant reduction in the total costs of handling RCCS can be achieved by burying the overall structures in the modules of the superficial storage by the bulk method, without additional fragmentation, followed by immobilization with a cement-sand or clay solution. The given approach for determining the specific activity of the entire concrete structure is based on conducting direct dosimetric and radiometric measurements and finding conversion coefficients, namely from the dose rate (DR, μSv /h) into radioactive surface pollution (RSP, Bq/m2). In order to convert the structure’s RSP into specific activity, it is necessary to distribute the volume of the radioactively contaminated part over the entire structure’s volume. The following are technical proposals for management and burying RCCS in a near-surface disposal facility with multi-barrier protection, which ensures reliable isolation of RCCS from the environment. It is noted the need to use safe technologies, which are based on the involvement of technical means and devices that make it possible to completely eliminate or minimize the involvement of personnel. Thus, the requirements of regulatory and operational-technical documents regarding the safe handling and disposal of RCCS must be met.

Published: August 2024

World experience in using industrially developed methods to condition radioactive waste (RAW) by way of their vitrification is addressed. The properties of waste forms produced in the countries with developed nuclear fuel cycle were analyzed using various glass formulations for further transportation, storage and burial of radioactive waste. It was stated that the use of borosilicate immobilizing matrices is recognized to be fully justified from the point of view of technological and economic advantages of their production, as well as the possibilities in ensuring the conditions for RAW safe temporary storage and transportation. In a number of phosphate glass modifications, lead-iron-phosphate formulations turned out to be the best from the point of view of provision of chemical resistance to the waste forms, as well as its resistance to devitrification during cooling and low corrosion impact on the equipment materials. The characteristics of vitrified radwaste and lava-like fuel-containing materials (LFCM) temporarily stored inside the Confinement complex (New Safe Confinement) and Shelter object of the SSE “Chornobyl NPP”, were compared. The conclusions were made regarding the influence of various factors on the properties of glass matrices and LFCM to retain hazardous radionuclides under the influence of various factors, including the self-radiation.
Promising Role of Machine learning and Artificial Intelligence in Pharmacy
Authors: Pounikar Yogesh
Published: August 2024

Machine learning (ML), a subset of Artificial intelligence (AI), has seen explosive growth in healthcare applications during the last several decades. In pharmacology, for example, AI and ML methods are used to analyze a wide variety of data, including the drug’s chemical structure, patient demographics, genetic information, and so on. The growing body of research on the use of AI in pharmacy is more evidence of this trend. Drug development and target identification are two areas where AI has been used effectively for some time now. Recently, however, AI models have emerged that can characterize patient populations and forecast an individual’s treatment response, thereby spanning the full drug development to the personalized medicine process. The use of AI in clinical pharmacology was a hot topic in 2020. Many of these programs have continued success and widespread usage. Many advances, however, have occurred since then.[1]
VACUUM BIREFRINGENCE AND DICHROISM IN A STRONG PLANE-WAVE BACKGROUND
Authors: Aleksandrov I. A. , Shabaev V. M.
Published: August 2024

In the present study, we consider the effects of vacuum birefringence and dichroism in strong electromagnetic fields. According to quantum electrodynamics, the vacuum state exhibits different refractive properties depending on the probe photon polarization and one also obtains different probabilities of the photon decay via production of electron-positron pairs. Here we investigate these two phenomena by means of several different approaches to computing the polarization operator. The external field is assumed to be a linearly polarized plane electromagnetic wave of arbitrary amplitude and frequency. Varying the probe-photon energy and the field parameters, we thoroughly examine the validity of the locally-constant field approximation (LCFA) and techniques involving perturbative expansions in terms of the external-field amplitude. Within the latter approach, we develop a numerical method based on a direct evaluation of the weak-field Feynman diagrams, which can be employed for investigating more complex external backgrounds. The polarization operator depends on two parameters: classical nonlinearity parameter ξ and the product η = ωq0/m2 of the laser field frequency ω and the photon energy q0 (m is the electron mass). The domains of validity of the approximate techniques in the ξη plane are explicitly identified.
BKT TRANSITION IN PHYLLOTAXIS
Authors: Nechaev S. K.
Published: August 2024

We explore a two-parameter renormalization group (RG) within the framework of the «energetic approach» introduced by L. Levitov, for the phyllotaxis model. Our focus lies on an equilibrium distribution of strongly repulsive particles situated on the surface of a finite cylinder. We investigate how these particles redistribute as the cylinder undergoes compression along its axis. Specifically, we construct the modular-invariant β-function for the system, which is explicitly expressed in terms of the Dedekind η-function. Utilizing this β-function, we derive equations that describe the RG flow near the bifurcation points, which mark the boundaries between different lattice configurations. By analyzing the structure of these RG equations, we assert the emergence of Berezinskii – Kosterlitz – Thouless transitions under significant cylinder compression.

Based on ethyl 1-amino-3,3-dimethyl-3,4-dihydronaphthalene-2-carboxylate (amino ester), a method for the synthesis of 5,5-dimethyl-3-(2-methylallyl)-2-thioxo-2,3,5,6-tetrahydrobenzo[h]quinazoline-4(1H)-one was developed. The latter was alkylated with halides of various structures, resulting in the production of 2-alkylsulfanyl-5,5-dimethyl-3-(2-methylallyl)-5, 6-dihydrobenzo[h]quinazoline-4(3H)-ones. By condensation of thioxobenzoquinazoline with hydrazine hydrate, 2-hydrazinyl-5,5-dimethyl-3-(2-methylallyl)-5,6-dihydrobenzo[h]quinazoline-4(3H)-one was synthesized, but similar reactions with 2-ethanolamine and 3-propanolamine proceeded abnormally with the formation of 2-(2-hydroxyethyl)amino-5,5-dimethyl-5,6-dihydrobenzo[h]quinazoline-4(3H)-one and 2-(3-hydroxypropyl)amino-5,5-dimethyl-5,6-dihydrobenzo[h]quinazoline-4(3H)-one, respectively. The interaction of the indicated thioxobenzoquinazoline with benzylamine proceeds with intramolecular cyclization with the formation of 6,6,10,10-tetramethyl-9,10-dihydro-5H-benzo[h]thiazolo[2,3-b]quinazoline-7(6H)-one. The antibacterial properties of the synthesized compounds were studied. It was found that the studied compounds have antibacterial activity.
South Africa: New Era?

Published: August 2024

The article is devoted to the general elections in South Africa, held on May 29, 2024 and their consequences. For the first time in 30 years after the dismantling of the apartheid regime, the African National Congress did not achieve a majority in parliament and had to look for cooperation with the parties that were in opposition. As a result, Cyril Ramaphosa was re-elected as president, and after difficult and long negotiations, on June 30, the formation of the Government of National Unity was announced. It was supported by 11 political parties, including the Democratic Alliance, which previously was the main opposition force. However, other major political parties - the Economic Freedom Fighters (EFF) and the Umkhonto We Sizwe party headed by former South African President Jacob Zuma - found themselves outside of it.
Food Security of African Small Island Developing States

Published: August 2024

The food security of African Small Island Developing States (SIDS) is one of the most important economic, social and humanitarian problems. A third of all the world’s hungry will come live on the African continent. The picture is even more acute for the SIDS due to the specifics of their geographical location, the structure of economy, the level of agricultural and food production development. Agriculture accounts for between 36% of GDP in the Comoros and 2.9% in the Seychelles. Along with undernourishment and nutritional deficiencies (“hidden hunger”), this group of countries is characterized by high rates of obesity and overweight. While there are common food security challenges, especially high levels of economic and environmental vulnerability, African SIDS approach them differently. Despite the illusory nature of achieving self-sufficiency in food, they nevertheless adopt government programs aimed at improving the efficiency of agri-food systems. However, some of them only (Seychelles and Mauritius) have government programs or strategies aimed at comprehensively addressing the food security problem. International organizations provide a lot of assistance to ensure food security for the population of African SIDS.

Jalan menuju Kantor Pusat Pemerintahan Provinsi Banten (KP3B) yang menjadi tujuan utama berbagai aktivitas administratif dan layanan publik sering kali menjadi titik kemacetan, meskipun kemacetan ini hanya terjadi pada beberapa lokasi tertentu namun masih menjadi masalah. Umumnya masyarakat atau pengguna jalan yang hendak melakukan rute perjalanan menuju/melewati kawasan tersebut menggunakan jalur jalan raya utama atau jalan raya provinsi, khususnya bagi masyarakat yang belum familiar terhadap rute/jalur perjalanan dari arah kawasan industri modern Kecamatan Cikande. Padahal jika dilihat dari jarak dan lalu lintas perjalanan, rute ini cukup padat. Untuk mengatasi permasalahan tersebut, diperlukan pendekatan sistematis guna mengoptimalkan perjalanan. Salah satu pendekatan teknik pencarian rute/jalur perjalanan adalah dengan menggunakan pendekatan algoritma Uniform Cost Search (UCS). Hasil analisis dan implementasi yang dilakukan menunjukkan bahwa rute alternatif yang direkomendasikan oleh algoritma UCS lebih efektif dibandingkan dengan jalur yang saat ini umumnya digunakan, berdasarkan kriteria jarak, kepadatan lalu lintas, kondisi jalan dan waktu tempuh.

Semakin pesatnya perkembangan teknologi informasi saat ini diperlukan kecepatan, ketepatan, serta keakuratan dalam pengolahan data. Teknologi Informasi dapat mempermudah manusia dalam pencarian informasi, hal ini membuat banyak instansi pemerintah memanfaatkannya dari sistem semi manual ke komputerisasi sehingga penyimpanan data dan informasi menjadi lebih efesien. Pada Stasiun Klimatologi terdapat 2 (dua) Stasiun Meteorologi Pertanian Khusus yaitu yang berada di Muaro Bulian dan Sunga 3. Dimana dalam proses pengiriman data SMPK masih dilakukan secara manual (Tulis tangan). Petugas yang bertugas di Stasiun Meteorologi Pertanian Khusus Muaro bulian dan Sungai 3 akan mendata informasi mengenai Pos Hujan, AGM1A (Bola Kering dan Bola Basah), AGM1B (Suhu Tanah Gundul, Suhu Tanah Rumput, Kecepatan Angin, Kelembapan Udara (RH) dan Suhu Air), intensitas Hujan dan Penguapan. Data tersebut akan dikirimkan kepada Stasiun Klimatologi Jambi secara berkala setiap bulannya. Berdasarkan kondisi tersebut, maka dalam hal ini penulis membuat sebuah aplikasi yang dituangkan dalam laporan hasil Kerja Praktek yang berjudul “Perancangan Sistem Informasi SMPK (Stasiun Meteorologi Pertanian Khusus) Berbasis Website Pada Stasiun Klimatologi Jambi. Yang akan dikembangan menggunakan model Waterfall, menggunakan Framework Laravel, lalu diimplementasikan menggunakan Bahasa pemograman PHP dan MySQL sebagai database.

Teknologi informasi sangat penting untuk lingkungan kerja modern, memfasilitasi penyelesaian tugas secara efisien dan memungkinkan penyebaran informasi secara global melalui internet. Didirikan pada tahun 2008, SMK Al-Bukhari di kecamatan Raas menawarkan dua jurusan: Rekayasa Perangkat Lunak (RPL) dan Teknik Komputer Jaringan (TKJ), yang melayani total 60 siswa. Saat ini, sekolah memiliki prosedur untuk mengusulkan surat keputusan terkait profesi mengajar yang diajukan ke dinas pendidikan bagi guru yang mencari peluang profesional. Namun, metode yang ada bermasalah karena mengandalkan proses manual dengan Ms. Excel untuk manajemen data dan Ms. Word untuk membuat surat pernyataan mengenai surat keputusan tunjangan profesi (SKTP). Untuk mengatasi masalah ini, sistem aplikasi prototipe untuk SKTP sedang dikembangkan. Sistem ini bertujuan untuk merampingkan proses penilaian yang dilakukan oleh guru dan menyederhanakan manajemen data SKTP bagi petugas administrasi. Dengan menerapkan aplikasi ini, SMK Al-Bukhari akan meningkatkan efisiensi dan akurasi penanganan data SKTP, menyediakan cara yang lebih mudah bagi guru untuk mengajukan usulan dan bagi petugas TU untuk mengelola data SKTP.

Published: August 2024

Background: CT Coronary Angiography (CTCA) is a non-invasive imaging modality with a high spatial and temporal resolution to diagnose coronary vascular disease. FBP (Filtered Back Projection) has limitations in improving the image quality, so iterative reconstruction is used on CTCA. Adaptive Iterative Dose Reduction (AIDR 3D) is one of the iterative reconstructions developed by Toshiba, which has three levels of strength: mild, standard, and strong. The study aimed to explain the application of AIDR 3D in improving image quality on coronary CT angiography examination. Methods: This research is descriptive with a literature study approach, using articles from NCBI, Science Direct, and Google Scholar. The keywords used are CT Coronary Angiography, AIDR 3D, and Image Quality. The articles obtained are reduced based on inclusion and exclusion criteria so that seven relevant articles are conducted for extraction.Results: The results showed that AIDR 3D could improve the quality of CTCA images with the most significant percentage in AIDR 3D strong by reducing noise 18-46.1% and increasing SNR 21-84.7% and CNR 21-82.2%.Conclusions: The application of AIDR 3D strong in obese patients with CTCA is good to use with standard kVp and 250-450 mA without increasing mA so that it does not increase the dose. AIDR 3D strong can also be used in patients with normal body mass with tube current adjusted according to the patient's body mass if there is no indication on the right coronary artery. AIDR 3D standard can be used in overweight patients and normal body mass.

The current healthcare insurance claim requires more procedures to be claimed from an insurance company. Healthcare insurance companies are crucial for patient financial assistance, but efficient claim processing can lead to lower the levels of care. Patients have already claimed insurance in certain locations and are attempting to claim it again in another location. This work proposes to increase claim speed, avoid fraudulent claims, and provide privacy for patient data on decentralized storage through permissioned blockchain. To ensure patient data privacy and assist insurance agents and individuals in verifying eligibility and claim status, hash values are used to store data in a block. Every claim’s information is stored in a block. If the patient attempts to claim again, the agent will validate the block and have the option to accept or reject the request. The integrity, speed, and security of patient health information can be achieved through this technique.
