Indicador de integridad de datos para un escenario de contratos futuros en una Blockchain
Authors: Ordóñez Quintero Cristian Camilo
Published: October 2023

La agricultura por contrato futuro se utiliza para acordar una serie de características especiales del producto para su posterior venta, la implementación de estos en una blockchain validado mediante contratos inteligentes conlleva una serie de desafíos, tal como la evaluación de las cláusulas utilizando datos externos a la blockchain (e.g, precio de moneda, alza de precios de fertilizantes, datos de sensores, bases de datos externas, datos meteorológicos o APIs que caracterizan cambios al validar las cláusulas estipuladas en el contrato) lo cual la manipulación o cambio sobre ellos perjudica los acuerdos pactados y afecta la iniciativa de comercio justo. La conexión de datos externos a una blockchain se conoce en la actualidad como dependencia del oráculo. Ahora bien, en caso de desconexión o falla de los datos proporcionados por el oráculo el contrato inteligente puede dejar de funcionar o incluso ejecutarse de manera incorrecta, lo cual conlleva a una serie de desafíos en su implementación. En ese sentido los indicadores de integridad de datos juegan un papel importante en este proceso, las firmas digitales, y el consenso distribuido, son algunos de los métodos que facilitan la verificación de integridad de los datos en los contratos inteligentes; si bien es cierto que son bastante utilizados, ninguno de los dos analiza el origen de los datos cuando éstos provienen de fuentes externas a la red. De esta manera la integridad del dato de oráculo es un proceso crítico que requiere una revisión detallada y medible teniendo en cuenta estándares que permitan comprender y validar la integridad del dato. Esto significa que los datos deben ser validados desde la procedencia del oráculo verificando fuentes confiables antes de ser incluidos en el contrato inteligente garantizando que el contrato se ejecute de manera efectiva y justa para todas las partes involucradas.
Rediseño del ciclo común de los programas de ingeniería. Una oportunidad para el trabajo transdisciplinar
Authors: García Vergara Sandra , Chacón Arias Olga Patricia , Lizcano Dallos Adriana , Carrillo Escobar Julio César
Published: October 2023

La apuesta nacional por el aseguramiento de la calidad de la Educación Superior centrada en el logro de los resultados de aprendizaje y el desarrollo de las competencias de los estudiantes ha llevado al interior de las instituciones universitarias a repensar sus procesos formativos. Para el caso de la Universidad Industrial de Santander-UIS esta revisión se ve permeada además por la apuesta institucional por la internacionalización, que promueve el abordaje de procesos de acreditación internacional como valor agregado. Actualmente, la UIS cuenta con tres programas de ingeniería acreditados con ABET y tres en proceso. La apropiación del modelo ABET y la normativa nacional dejaron en evidencia la necesidad de revisión del proceso formativo en los programas de ingeniería, particularmente durante los primeros cuatro semestres que conforman el ciclo básico (matemáticas, física y química) para asegurar una articulación efectiva entre el desarrollo de las competencias en ciencias básicas, con las previstas en el ciclo profesional. Este trabajo presenta la experiencia de la reformulación de un ciclo básico para los programas de ingeniería, a partir de la construcción colectiva entre los profesores de las Facultades de Ingenierías y de Ciencias, partiendo de los resultados de aprendizaje, las experiencias de diseño y las observaciones planteadas por los comités consultivos de los programas. La experiencia implementada ha mostrado la necesidad de lograr una comunicación asertiva y eficaz para consolidar acuerdos didácticos que se expresan en los planes de actividad académica, pero que trascienden la estructura organizacional por Escuelas y Facultades, e implican la comunicación continua en la implementación y seguimiento a dichos planes, así como el desarrollo de estrategias institucionales de mejoramiento continuo, diagnóstico y apoyo al estudiante en la transición a la Educación Superior.

Effect of streaming process on the quality of wheat (Triticum aestivum L.) kernel
during extraction
Authors: Sulaimana A.S. , Yudhistira B.
Published: October 2023

Streaming is a process of routing wheat flour streams to produce flour products and
continuing with the milling process using plan-sifters. This machine has six ranges of
opening mesh that produce six-grain granulations divided into several flour streams. This
study aimed to assess the streaming process effect on the quality changes of wheat kernel
extraction. The triplicates observation was conducted on the same 56 flour streams with
different multi-wheat blends. The ash, protein, moisture, and gluten quality of blended
wheat were analyzed. The streaming process significantly changed grain quality
(p<0.001). Increasing the mesh width in the streaming process increased ash content
(p<0.05) and protein content (p<0.05). In addition, there was a decrease in water content
(p<0.05) and gluten content (p<0.05) at a wider mesh opening. The streaming process
produces more than 72% wheat flour. This study showed the vital role of the streaming
process in the quality determination of wheat flour produced.
Constraining factors influencing the production of coconut among smallholders
in Batu Pahat, Johor, Malaysia
Authors: Omar Z. , Saili A.R. , Abdul Fatah F. , Wan Noranida W.M.N.
Published: October 2023

Malaysia is one of the top ten coconut-producing nations in the world, and coconut is the
country's fourth-most significant industrial crop after oil palm, rice, and rubber. Coconut
production is an important source of income and employment for over 100,000
households that rely entirely or partially on coconut, particularly among smallholders. The
sector has given smallholder farmers the option to diversify their resources for coconut
farming while also meeting local demand for fresh consumption and the coconut
processing industry. Coconut smallholders were experiencing a productivity gap as a
result of differences in agricultural techniques, socioeconomic situations, and economic
factors such as demand and supply, which resulted in price volatility and varying
profitability of coconut. The current study looked into topics such as socioeconomic status
as well as factors and constraints that affected coconut production profitability and
technical efficiency among smallholders in Batu Pahat, Johor, Malaysia. A random
selection procedure was used to pick a sample of 152 smallholders. The Kaiser-MeyerOlkin (KMO) for exploratory factor analysis (EFA), was 0.716, indicating that all items
were of excellent quality and reliability. A higher EFA score indicates that the government
factor, followed by knowledge and agronomic methods, was the most important factor
influencing smallholders' profitability and technical efficiency in their coconut production
in Batu Pahat, Johor. The major constraints were a lack of expertise, the volatility of the
coconut price, and a lack of technology.
The industrial design of a robotic device for upper-limb stroke rehabilitation
Authors:   , ChongSheng Guo Tiger
Published: October 2023

Over 16.9 million people worldwide suffer a stroke annually (Feigin et al., 2014, p. 2). Up to 80% of stroke survivors suffer weakness or paralysis in one half of their body, frequently compromising their ability to lead an independent life (Alankus, Lazar, May, & Kelleher, 2010; Buma, Lindeman, Ramsey, & Kwakkel, 2010, p. 589). In order to promote recovery, stroke survivors are recommended to participate in rehabilitation through intensive and repetitive training (McLaren et al., 2020). Robotic rehabilitative devices are a promising tool in assisting stroke rehabilitation, increasing the ability for clinicians to treat more individuals, and facilitating the ability for rehabilitation to be completed at home. However, robotic rehabilitative devices are poorly accepted by users, and experience high levels of rejection and abandonment (Cruz, Emmel, Manzini, & Braga Mendes, 2016). Based on current models of acceptability, it is suggested that this low acceptability is derived from poor user perceptions of ease of use, usefulness, enjoyment, adaptivity, around robotic rehabilitative devices, as well as product- related stigma (Heerink, Kröse, Evers, & Wielinga, 2010; Vaes, 2014a). Instigated by this, this study adopted an empathic, user-centred design model that aimed to implement industrial design to improve the acceptability of these devices. This comprised of the extensive iterative redesign of an existing robotic rehabilitative device, with frequent engagement from stakeholders. This device, alongside the original device, was then tested through trials, questionnaires, and interviews. Results from our study indicate industrial design strategies facilitated meaningful improvements to many dimensions of acceptability. Furthermore, our research identified several novel connections between dimensions of acceptability, and that design may strongly influence them.
Microemulsion electrolytes for electrochemical energy storage devices
Authors:   , Hughson Fraser
Published: October 2023

The demand for electrical energy storage technology is growing at a rapid pace. The current market leader is the lithium ion battery which has found use in many applications from stationary, grid level storage to transportation and smaller applications like mobile phones.

Supercapacitors are an up-and-coming alternative energy storage technology that compliments lithium ion batteries in many ways. Where lithium ion batteries have a high energy density, delivering energy for a long time, supercapacitors have a high power density which means they are capable of being charged and discharged within seconds.

Both of these technologies rely on organic electrolytes that are toxic and flammable. Replacing these organic electrolytes with alternatives would go a long way to improving their sustainability and lessening the environmental impact. Using a water based electrolyte is an attractive option however water is limited by its electrochemical window. Above a voltage of 1.23 V it is thermodynamically favourable for water to be split into hydrogen and oxygen gasses. This voltage restriction limits the energy density of water based batteries and supercapacitors making them economically non-viable. The research in this thesis was investigating the use of microemulsions as an alternative class of electrolytes in ion batteries and supercapacitors. Microemulsions are a thermodynamically stable mixture of two immiscible phases. Despite being mostly made up of water, microemulsions can have a greatly extended electrochemical window, as much as 5 V. This means that they could have all of the benefits of aqueous and organic electrolytes in one solvent. Microemsulions have never been applied to supercapacitors or ion batteries before. They were found to retain their enhanced electrochemical stability and still allow for the devices to perform. In almost all aspects the devices presented within out-perform any other water based electrolyte in the literature and in many cases show comparable performance to organic electrolytes.
An Artistic Wasteland? Visual Images of the 1920s in New Zealand
Authors:   , Lineham Brett
Published: October 2023

Commentary in art history and criticism about the art of the 1920s in New Zealand is limited, with contemporary discussion focusing on art education and La Trobe scheme teachers, local admiration for British Victorian art and the rejection of modernist painting, as well as the work of some of New Zealand’s most talented artists as expatriates in Europe. The most egregious verdict about art in the 1920s was that of Auckland Art Gallery Director Peter Tomory in the 1950s, subsequently endorsed by some influential art historians, that fine arts in New Zealand was a “wasteland” in the 1920s. This view provided the motivation for this thesis.

The thesis uses a visual culture approach, supplemented by Foucauldian discourse analysis, to investigate the broader arts environment of the 1920s. This provides a much broader and more diverse position and data set than if the analysis was limited to fine art alone. Visual material created by cartoon artists, commercial artists and photographers, as well as fine artists, enhances an understanding of the discourses covering an important period in New Zealand’s art history.

The 1920s were a period of significant societal change. Having emerged from a period of war and pandemic, New Zealand embarked on a sweeping process of social, economic and political development. In chapters on Society, the Economy, Politics and Art and Culture, a number of common themes are evident such as immigration, economic change including land ownership, recession, meeting infrastructural needs, and uncertainties in New Zealand’s relations with Great Britain.

Political discourses explored in the thesis include politicians grappling with recession and working class demands, quality and effectiveness of political leadership, the rise of the Labour Party and debate over “Bolshevist” allegiances. All these issues appear to have stimulated socially-conscious artists to develop a range of imagery that tells a compelling story of the time.

Examples of the art being created by New Zealand artists here and overseas are reviewed with visual evidence supporting the rejection of the criticism that the 1920s were a wasteland for art. With new art galleries opening, modernism becoming more widely accepted, and the large number of amateur artists unwilling to accept the critics’ judgement that their art did not fit in the pursuit of a national cultural identity, a firm foundation for the future of New Zealand’s art was laid in the 1920s.

El odio digital, presente en el ecosistema mediático, emergió durante el partido de fútbol de la primera división española entre el Cádiz C.F y el Valencia C.F. Tras un incidente presuntamente racista —que posteriormente no pudo ser oficialmente comprobado— se originó una polémica en Twitter de impacto nacional e internacional. El objetivo principal es analizar el comportamiento de los usuarios de Twitter que participaron de dicha polémica generada en el campo de fútbol. A través de un análisis cualitativo sustentado en la Teoría Fundamentada, profundizamos en las 7.890 respuestas que se produjeron a raíz de los tuits emitidos desde las cuentas oficiales de los clubes y de los jugadores implicados. De los resultados recogidos extraemos las conclusiones: a) El sentimiento de odio y de crispación está presente mientras permanece la polémica; b) Se detecta una ausencia total de debate objetivo cuando el odio está presente; c) En ninguna de las cuentas oficiales analizadas se observa un intervencionismo a través del community manager.
Predicting Software Change-Proneness From Software Evolution Using Machine Learning Methods
Authors: A Shatnawi Raed
Published: October 2023

Aim/Purpose: To predict the change-proneness of software from the continuous evolution using machine learning methods. To identify when software changes become statistically significant and how metrics change.

Background: Software evolution is the most time-consuming activity after a software release. Understanding evolution patterns aids in understanding post-release software activities. Many methodologies have been proposed to comprehend software evolution and growth. As a result, change prediction is critical for future software maintenance.

Methodology: I propose using machine learning methods to predict change-prone classes. Classes that are expected to change in future releases were defined as change-prone. The previous release was only considered by the researchers to define change-proneness. In this study, I use the evolution of software to redefine change-proneness. Many snapshots of software were studied to determine when changes became statistically significant, and snapshots were taken biweekly. The research was validated by looking at the evolution of five large open-source systems.

Contribution: In this study, I use the evolution of software to redefine change-proneness. The research was validated by looking at the evolution of five large open-source systems.

Findings: Software metrics can measure the significance of evolution in software. In addition, metric values change within different periods and the significance of change should be considered for each metric separately. For five classifiers, change-proneness prediction models were trained on one snapshot and tested on the next. In most snapshots, the prediction performance was excellent. For example, for Eclipse, the F-measure values were between 80 and 94. For other systems, the F-measure values were higher than 75 for most snapshots.

Recommendations for Practitioners: Software change happens frequently in the evolution of software; however, the significance of change happens over a considerable length of time and this time should be considered when evaluating the quality of software.

Recommendation for Researchers: Researchers should consider the significance of change when studying software evolution. Software changes should be taken from different perspectives besides the size or length of the code.

Impact on Society: Software quality management is affected by the continuous evolution of projects. Knowing the appropriate time for software maintenance reduces the costs and impacts of software changes.

Future Research: Studying the significance of software evolution for software refactoring helps improve the internal quality of software code.
ГЕЙМІФІКАЦІЯ ЯК ІНСТРУМЕНТ СТРАТЕГІЧНОГО УПРАВЛІННЯ РОЗВИТКОМ ЛЮДСЬКОГО КАПІТАЛУ
Authors: Ліпич Любов
Published: October 2023

Мета статті  - охарактеризувати такий  інструмент стратегічного управління як  геймифікація та її здатність за короткий час підвищувати ефективність управління людським капіталом при збереженні раціональності цього управління. Встановлено, що сучасні визначення стратегічного управління акцентують увагу на таких його аспектах: стабільність конкурентних позицій, стійкість довготривалих результатів, правильність реакцій на зміни у зовнішньому середовищі.  Це вказує на необхідність співвіднесення стратегічного управління людським капіталом зі стратегічним управлінням  підприємством таким чином, щоб цілі щодо потреб у ресурсах для досягнення цих цілей були максимально співставними. Тобто, стратегія розвитку людського капіталу повинна випливати із загальної стратегії розвитку підприємства.

Доведено, що стратегія розвитку людського капіталу повинна ідентифікувати методи управління ним, щоб максимально швидко і ефективно досягати поставлених цілей.  Найефективнішим методом переконання команди досягти цілей є  мотивація. Проте популярні форми мотивації  не працюють в довгостроковій перспективі. Тобто, йдеться про перехід від купівлі працівників до формування їхньої відданості. Ефективне залучення є результатом не  економічних вигод, а внутрішніх переконань, які є результатом змінних, пов’язаних з організаційною культурою.

Обґрунтована необхідність впровадження такого інструменту стратегічного управління як геймифікація в загальну стратегію розвитку людського капіталу. Завдання стратегічного управління людським капіталом полягає в тому, щоб  зібрати лояльних, висококваліфікованих і відповідальних працівників, відданих і мотивованих для досягнення довгострокових цілей. Відповіддю на ці вимоги є гейміфікація -  спосіб впливу на людську поведінку, який базується на використанні ігрових елементів. За своєю концепцією ігри схожі на стратегію, оскільки вони мають структуру, правила та цілі. Подібно до стратегічного управління на підприємстві, у грі ми досягаємо мети (перемоги), виконуючи певні завдання. Висока варіативність  ігор забезпечує здатність працівників адаптуватися до середовища. У сучасній економіці лише гнучкі організації здатні швидко реалізовувати нестандартні замовлення, і цьому сприяє гейміфікація.
THE INTERACTION BETWEEN COGNITIVE BIASES AND THE CULTURAL DIMENSIONS OF THE COUNTRY IN INDIVIDUAL INVESTMENT DECISIONS
Authors: KOMŞUOĞLU YILMAZ Nurgün
Published: October 2023

There are many physical, psychological, and social factors that have an impact on the decision-making process. Subjective cognitive factors that affect this process are called cognitive biases. Cognitive biases can impede people from making the right decisions by affecting their objective behavior in decision-making. This situation comes to the fore, especially in financial investment decisions and investors move away from making optimal decisions due to various cognitive biases. Culture has a significant impact on the way of life and thinking of people living in a country. The cultural characteristics of the country may have an impact on the prominence of different cognitive biases. In this study, the relationship between cultural dimensions and cognitive biases was examined in terms of individual financial investments in Türkiye.

Authors: Hadi Amerah Abdel , Hassan Alaa Jawad
Published: October 2023

Background : Scabies (Sarcoptes scabiei var. hominis) is one of the parasitic diseases that is often ignored. It results in problems that trigger an allergic and inflammatory immunological response. Cytokines are crucial to the development of disease and its pathophysiology. This investigation looked at how scabies risk and a variation in the gene IL-6 affected IL-6 production.

Materials and Methods : The goal of the current investigation was to determine the level of IL-6 by ELISA and its linked with IL-6(-174 G/C) polymorphisms in 60 scabietic patients and 30 healthy individuals.

Results : In contrast, the IL-6(-174 G/C) CC genotype and C allele carrier frequencies were highly significant (P0.05) in the patients who had their first infestation. The results showed a significant increase (P0.05) in the IL-6(-174 G/C) GG genotype and G allele in the re-infestation group of patients compared to the healthy group. According to IL-6 genetic variations, low serum levels were connected with the CC genotype.

Conclusion : IL-6(-174 G/C) Scabies susceptibility and polymorphism were related, providing evidence for the hereditary basis of the illness

Authors: Hanny Nirwani  , Hidayati Rini , Perdinan
Published: October 2023

Thermal comfort refers to the suitability of meteorological conditions for humans with the environment. Temperature is the main meteorological variable, which determines the thermal comfort as expressed in various climate indices. This study aims to analysis the distribution of thermal comfort, and to identify environmental factors influencing the comfort situated in North Sumatra, Indonesia. We applied the Universal Thermal Climate Index (UTCI) to determine the heat stress level for 2011 - 2020. The higher UTCI value indicates more uncomfortable conditions related to the higher heat stress. The results showed that the average value of UTCI in North Sumatra was categorised at moderate heat stress. Densely urbanised area in the eastern region contributed to high heat stress, whereas mountainous areas in central to west regions were at low level. Our findings found that climate season affected the distribution of heat stress level. The low heat stress occurred in December-February, while high heat stress happened in June-August. Further, findings revealed that altitude and land cover have contributed to UTCI variation by more than 75% variance.

Analisis Faktor-Faktor yang Berpengaruh terhadap Sikap Pengguna Aset Digital Non-Fungible Token Berbasis Blockchain pada Komunitas NFT Indonesia
Authors: Muhamad Ramdani Risma , Sumarwan Ujang , Hermadi Irman
Published: October 2023

Blockchain is an inspiring new technology that requires a lot of attention from various researchers and companies. This technology offers various benefits, where the newest derivative of this technology is Non-Fungible Tokens (NFT). In NFT, various digital assets such as images, videos, music or virtual creations are traded. The relatively new NFT creates a lack of user knowledge to be able to utilize this technology as a digital asset for trading. On the one hand, users welcome the use of NFTs as a tool to gain financial gain, but on the other hand, there are users who doubt the long-term success of NFTs as a form of investment and see them as a temporary trend that may be detrimental in the event of a market crash. The purpose of this research is to explore various factors that can impact the attitudes of NFT users. The research used a quantitative method which was carried out at the Indonesian NFT Community, involving 377 respondents as a sample. Questionnaires were distributed online using the Google form on the Telegram platform. The data analysis used in this research is by using Structural Equation Modeling (SEM). The results of the study show that there are five factors that significantly influence the attitude of NFT users. Perceived ease of use, perceived usefulness, perceived trust, and personal innovativeness have a positive and significant effect on user attitudes, while perceived risk has a negative effect and is one of the factors that has the most impact on user attitudes than other factors, followed by perceived trust in the second position as the most dominant variable. So like any new technology, NFTs have risks and trust issues that most users consider.
Evaluasi Emergent Strategy Bisnis PLTS Atap PT X sehubungan dengan Ketidakpastian Strategis Permintaan Pasar
Authors: Sutopo Primisita , Rossieta Hilda
Published: October 2023

PT X is one of the developers of rooftop solar photovoltaic (PV) power plants in the commercial and industrial sectors in Indonesia. Over time, there has been a strategic uncertainty of market demand since 2022, mainly affected by the strong bargaining position of Wilayah Usaha's state-owned enterprise (Wilus SOE). Wilus SOE plays a significant role, is given priority in the provision of electricity for the public interest as stipulated in the regulation, and also has a dominant share (95 percent in 2020), making it a de facto monopoly in the electricity business in Indonesia. Wilus SOE has legitimacy as a power distributor and therefore has the authority to approve the capacity of rooftop solar PV power plants. Referring to this situation, this research aims to identify the intended strategy of PT X and the emergent strategy in dealing with the strategic uncertainty of market demand. PESTEL analysis (political, economic, sociocultural, technological, environmental, legal) and five-forces framework (competitive rivalry, new entrants, substitute products, suppliers, customers), as well as emergent strategy evaluation, were used as the framework of this research. To strengthen the analysis results, in-depth interviews were also conducted with the management team of PT X. Based on the series of analyses, it can be concluded that PT X's business is strongly influenced by legal factors while the competitive rivalry and customers' factor have very strong forces. On the other hand, PT X has implemented an emergent strategy well in dealing with the strategic uncertainty of market demand, as an effort to maintain the company's profitability. This research is expected to provide benefits for PT X and other rooftop solar PV power plant developers to understand the emergent strategy in order to remain competitive in its business implementation.

In developing countries like Nigeria, malaria and typhoid fever are major health challenges in society today. The symptoms vary and can lead to other illnesses in the body which include prolonged fever, fatigue, nausea, headaches, and the risk of contracting infection occurring concurrently if not properly diagnosed and treated. There is a strong need for cost-effective technologies to manage disease processes and reduce morbidity and mortality in developing countries. Some of the challenging issues confronting healthcare are lack of proper processing of data and delay in the dissemination of health information, which often causes delays in the provision of results and poor quality of service delivery. This paper addressed the weaknesses of the existing system through the development of an Artificial Intelligence (AI) driven extended diagnostic system (EDS). The dataset was obtained from patients’ historical records from the Lagos University Teaching Hospital (LUTH) and contained two-hundred and fifty (250) records with five (5) attributes such as risk level, gender, symptom 1, symptom 2, and ailment type. The malaria and typhoid dataset was pre-processed and cleansed to remove unwanted data and information. The EDS was developed using the Naive Bayes technique and implemented using software development tools. The performance of the system was evaluated using the following known metrics: accuracies of true positive (TP), true negative (TN), false positive (FP), and false negative (FN). The performance of the EDS was substantially significant for both malaria and typhoid fevers.

У статті розглянуто питання оцінки математичного сподівання кількості знищених засобів повітряного нападу угрупованням зенітних ракетних військ при здійсненні зенітного ракетного прикриття об’єктів. Даний показник оцінюється в умовах максимальної реалізації вогневих можливостей при застосуванні способу вогневого ураження – розосередження вогню для нанесення повітряному противнику максимальних втрат. Виходячи з наявної інформації про повітряного противника, запропоновано дві різні моделі (стохастична і детермінована) визначення математичного сподівання кількості знищених засобів повітряного нападу, які враховують кількісно-якісний склад повітряного удару противника. Розроблена методика оцінки математичного сподівання кількості знищених засобів повітряного нападу угрупованням зенітних ракетних військ може бути реалізована без застосування геоінформаційних систем і застосована для проведення швидких оперативно-тактичних розрахунків, з урахуванням кількісно-якісного складу повітряного удару по об’єкту прикриття. Також можливо її використовувати для рішення задач оптимізації бойових порядків через врахування розміщення позицій вогневих підрозділів відносно об’єкта прикриття і відносно невеликої кількості розрахунків.

Розглядається завдання підвищення оперативності та адекватності автоматизованого пошуку зображень, які найбільш близькі до заданого зображення за складом представлених у ньому об’єктів та їх локальності, у системах управління великими сховищами зображень. Пропонується метод порівняння зображень, який забезпечить вилучення інформації про об’єкти зображення на основі використання на першому етапі каскадного процесу парадигми клітинних нейронних мереж, зберігання цієї інформації у службових полях файлів зображень, а також можливості використання різних метрик порівняння зображень, виходячи з особливостей завдання, що вирішується. Базовий показник визначає коефіцієнт подібності на основі типів та кількості об’єктів на порівнюваних зображеннях. Рамковий показник визначає коефіцієнт подібності з урахуванням розташування окремих об’єктів та їх перетинів на зображеннях. Матричний показник, орієнтований на обробку зображення з великою кількістю об’єктів, визначає коефіцієнти подібності з урахуванням площі перетину, займаної об’єктами певного типу. Ефективність показників порівняння залежить від типу зображень і певних умов, що робить доцільним їх системне застосування в рамках одного методу.

Розглянуто проблему кластеризації великих масивів даних, що послідовно надходять на обробку. В основі підходу, що пропонується, покладено ідею достовірної кластеризації, представлену у рекурентній формі. Оскільки у загальному випадку цільова функція кластеризації є багатоекстремальною, з невідомою кількістю локальних оптимумів, запропоновано алгоритм пошуку глобального екстремуму, що за суттю є гібридом ройового алгоритму косяків риб, випадкового пошуку та еволюційного планування на основі метода Нелдера-Міда. Запропонований підхід є достатньо простим у числовій реалізації, дозволяє знаходити глобальні екстремуми складних функцій, що підтверджується результатами числового експерименту.

Although hearing impaired people represent a significant group of handicapped people, only a few studies examine their physical activities. This study was performed in the Spring of 2019 in Debrecen, Hungary by recruiting 86 hearing impaired people. Here the frequency and type of their physical activity as well as their motivation was examined. Average age of the subjects was 42.0±16.9 years, 41.9% of them performs regular physical activity. Out of them 54.1% excercises twice a week, the rest even more often. Soccer, jogging, and cycling were the most preferred sports. Percentage of hearing impaired people performing regular physical activity was about the same as it was for people with normal hearing. Reason for motivation – it makes them happy and they feel better due to the physical activity – or staying at home – their health condition limits them and they have little free time – was also similar in both groups. However, 80% of the people with impaired hearing preferred to do physicial activity together other hearing impaired.

Water quality and treatment are becoming of increasing concern. It is important to develop renewable bio-coagulants to treat turbid water. This study suggests plant-based coagulants as substitute for chemical coagulants. The plants used were Moringa oleifera (MO), Carica papaya (CP) seeds, and aloe vera (AV) rind which are readily available in most communities. These contain water-soluble substances that have coagulation activity in water. The coagulation efficiency of these plants, at different dose were studied and compared with aluminum sulfate (AS), the most used chemical coagulant.
All coagulants were most effective at 0.40 g/L dose. Among the coagulants used, MO outstands in interface height variation, settling rate and TSS removal of 71.79%. With 98.00%, it also has the highest color removal together with alum. The latter also has the highest turbidity removal with 96.40% and contributed to greater rise in DO levels. However, using alum turned the water acidic. The pH exhibited variations through coagulation, Moringa oleifera yielded to smallest pH variation.

Climate change and greenhouse gas emissions are some of the most noted topics of the last years. Carbon footprint calculators provide an interesting solution when it comes to informing people about the above topic. These calculators try to estimate the carbon footprint, the total amount of greenhouse gas emissions, based on information provided by the user that is related to various activities that may result in creating emissions. Some of the calculators also provide recommendations to the users, based on their results, in order to reduce their carbon emissions. This study provides a comparative analysis of the indicators used for calculating carbon footprint in available household calculators, as well as the recommendations provided for the users to reduce their footprint. The goal of this paper is to present the current state of household carbon footprint calculators regarding the data they require from their users in order for them to calculate their carbon footprint and any recommendation they may provide based on the results. This is achieved by analyzing a list of carbon footprint calculators that are freely available online and, specifically, the domains and indicators each calculator uses, along with the associated resulting recommendations.

Honey is rich in phenolic and flavonoid compounds that have the potential as antioxidants. The heating treatment of honey is also known to affect the honey compound. This study aimed to determine the best Indonesian A. dorsata honey from various locations based on the level of total phenolics compounds, flavonoids, and antioxidant capacity due to variations in heating temperature. The procedures carried out in this study included: heating the sample with variations (room temperature, 65 oC, and 121 oC), measuring total phenolic content using the Folin-Ciocalteau method, measuring total flavonoid content using the AlCl3 colorimetric method, and testing antioxidant activity using the DPPH method. Each honey's total phenolic, flavonoid, and antioxidant activity are affected by its origin. The impact of heating at 65 oC and 121 oC resulted in various changes between honey samples (p<0.05). The best A. dorsata honey overall was found in Flores honey after heating at 121 oC heating treatment with total phenolic content of 4.96 mgGAE/mL, total flavonoids of 1.173 mg QE/mL, and IC50 5.76 g/L.
