Published: June 2023

Learning Health System (LHS) and integrated care are challenged due to a fragmented health data landscape. An information model is agnostic to the underlying data structures and can potentially contribute to mitigating some of the gaps. In a research project, Valkyrie, we are exploring how metadata can be organized and used to promote service coordination and interoperability across levels of care. An information model is viewed as central in this context and as a future integrated LHS support. We examined the literature regarding property requirements for data, information and knowledge models in the context of semantic interoperability and an LHS. The requirements were elicited and synthesized into five guiding principles as a vocabulary to inform the information model design of Valkyrie. Further research on requirements and guiding principles for information model design and evaluation are welcomed.

Loneliness is a global public health issues contributing to a variety of mental and physical health issues. It also increases the risk of life-threatening conditions as well as contributes to burden on the economy in terms of the number of days lost to productivity. Loneliness is a highly varied concept though, which is a result of multiple factors. To understand loneliness this paper carries out a comparative analysis of USA and India through Twitter data on the keywords associated with loneliness. The comparative analysis on loneliness is in the vein of comparative public health literature and to contribute to develop a global public health map on loneliness. The results showed that the dynamics of loneliness through the topics correlated vary across geographical locations. Social media data can be used to capture the dynamics of loneliness which can vary from one place to another depending on the socioeconomic and cultural norms and sociopolitical policies.
The use of fluorescence laparoscopy in the resection of splenic tissue replantation in the right lobe of the liver: A case report and literature review
Authors: Wu Bao-Qiang , Zhang Xu-Dong , Zhu Chun-Fu , Qin Xi-Hu
Published: June 2023

BACKGROUND: Ectopic replantation and regeneration of splenic tissue fragments following splenic trauma or splenectomy is known as replantation of splenic tissue. It typically takes place in the abdominal cavity, however, splenic tissue replantation in the liver is extremely rare and difficult to diagnose. It is often misdiagnosed as a liver tumor and removed. CASE PRESENTATION: We present the case of a patient with a history of traumatic splenectomy 15 years prior to the replantation of splenic tissue in the liver. A 4 cm mass in the liver was found during the most recent physical examination, and a computed tomography scan indicated the possibility of a malignant tumor. The tumor was then removed using fluorescence laparoscopy. CONCLUSION: There is a possibility of intrahepatic replantation of splenic tissue in patients who have had a splenectomy in the past, have recently discovered an intrahepatic space-occupying lesion, and do not have any high-risk factors for liver cancer. Unnecessary surgery can be avoided if 99mTc-labeled red blood cells imaging using mass puncture or radionuclide examination provides a clear preoperative diagnosis. Globally, there are no reports of the use of fluorescence laparoscopy in resecting replanted splenic tissue in the liver. Specifically, in the current case, there was no indocyanine green uptake in the mass, and only a small amount was found in the normally functioning liver tissue surrounding the tumor.

Published: June 2023

BACKGROUND: Stress urinary incontinence is prevalent among women and the incidence increases with age. OBJECTIVE: To explore the effect of intelligent pelvic floor muscle rehabilitation on elderly female patients with incontinence. METHODS: A total of 209 patients with urinary incontinence who were treated with pelvic floor muscle rehabilitation at Peking University International Hospital from September 2020 to January 2022 were selected by convenient sampling. All subjects were divided into the 50–60 year old patient group (n= 51) and over 60 years old patient group according to age (n= 158). The subjects of different age group were divided into an experimental group and a control group. The patients in the control group received routine nursing and health education, and the patients in the observation group received a combination of mobile application use and smart dumbbells. Based on this, we constructed an intervention model for intelligent, continuous pelvic floor rehabilitation. After 7 and 12 weeks, pelvic floor muscle function knowledge and exercise compliance in the two groups were evaluated. The improvement of urinary incontinence symptoms, pelvic floor muscle strength grades and quality-of-life scales were evaluated. RESULTS: The results showed that pelvic floor knowledge and exercise compliance in the experimental group were better than in the control group at 7 and 12 weeks after intervention (P< 0.05). There was no significant difference in pelvic floor muscle strength and quality of life between the two groups at 7 weeks after intervention (P> 0.05). However, there was a significant difference in pelvic floor muscle strength and quality of life between the two groups at 12 weeks after intervention (P< 0.05). There was no significant difference between different age groups. CONCLUSION: The intelligent pelvic floor rehabilitation model that combines a mobile application with smart dumbbells can maintain and strengthen the clinical treatment effect for elderly patients with urinary incontinence.

Published: June 2023

BACKGROUND: Hepatitis B Virus (HBV) reactivation is the most common complication for patients with primary liver cancer (PLC) after radiotherapy. How to reduce the reactivation of HBV has been a hot topic in the study of postoperative radiotherapy for liver cancer. OBJECTIVE: To find out the inducement of HBV reactivation, a feature selection algorithm (MIC-CS) using maximum information coefficient (MIC) combined with cosine similarity (CS) was proposed to screen the risk factors that may affect HBV reactivation. METHOD: Firstly, different factors were coded and MIC between patients was calculated to acquire the association between different factors and HBV reactivation. Secondly, a cosine similarity algorithm was constructed to calculate the similarity relationship between different factors, thus removing redundant information. Finally, combined with the weight of the two, the potential risk factors were sorted and the key factors leading to HBV reactivation were selected. RESULTS: The results indicated that HBV baseline, external boundary, TNM, KPS score, VD, AFP, and Child-Pugh could lead to HBV reactivation after radiotherapy. The classification model was constructed for the above factors, with the highest classification accuracy of 84% and the AUC value of 0.71. CONCLUSION: Comparing multiple feature selection methods, the results showed that the effect of the MIC-CS was significantly better than MIM, CMIM, and mRMR, so it has a very broad application prospect.

BACKGROUND: Situation, Background, Assessment, and Recommendation (SBAR) is a structured method for communicating critical information that requires immediate attention and action. OBJECTIVE: To study the effects of empathy nursing combined with the SBAR communication system on the negative emotions and nursing quality of children undergoing tracheotomy. METHODS: This is a clinical observational study. A total of 100 tracheotomy patients who were cared for in the pediatric intensive care unit (subsequent treatment in the tracheotomy clinic or otolaryngology ward) of our hospital from September 2021 to June 2022 were recruited and assigned at a ratio of 1:1 either into a control group (empathic care) or an observation group (empathic care combined with SBAR) using a randomized method. Further, the postoperative anxiety self-rating scale scores, negative emotions, hope index, and nursing quality were compared between the two groups. RESULTS: After nursing, the psychological resilience scale score of the observation group was higher than that of the control group, whereas the anxiety self-rating scale score was significantly lower than that of the control group (all P< 0.05). Basic and special nursing, knowledge awareness, and safety management of the two groups of patients improved significantly, with higher results in the observation group than in the control group (P< 0.05). CONCLUSION: Empathy nursing combined with the SBAR communication system considerably improves postoperative negative emotions and enhances the quality of nursing care for patients undergoing tracheotomy.

Authors: Chorna Kristina
Published: June 2023

The purpose of the article is to identify the features of documentary drama as a new genre education of domestic television; to study and generalize the subjective and objective aspects of its effective functioning in the context of postmodern tendencies and the process of infotainment of the media space. Methodology. The historical-cultural method was applied, which helped to study various aspects of the origin and development of documentary drama in retrospect, as well as to understand the formation of the genre in the context of the specifics of domestic television space at the beginning of the XXI century; typological, thanks to which the attributive characteristics of the docudrama are revealed; a comparative method, the application of which made it possible to compare the characteristic features of foreign and domestic docudrama. Scientific novelty. Documentary drama as a specific genre education of foreign television in the second half of the twentieth century has been studied. and the peculiarities of the origin and development of the docudrama on Ukrainian television have been clarified. It is stated that the direction of development of modern television documentary in general and the genre of documentary drama in particular, is due to the specifics of the artistic search for postmodernism, aimed at expressing the inner life of man. It was revealed that the typical features of infotainment (artificially enhanced plot drama; thematic direction designed to enhance the emotional response of the viewer; approximation of drama to the formulas of the Hollywood film industry, etc.) first clearly manifested in the American docudrama. Conclusions. In the process of finding ways to synthesize documentary and non-documentary, Ukrainian television art seeks to find ways to solve complex in-depth problems, in particular innovative opportunities to create universal genre and species forms. The study showed that the development of domestic television documentaries (the early 2000s) takes place mainly in the format of infotainment - the desire to make it commercially successful and popular leads to integration into the global process of creating entertainment television. At the present stage, the docudrama, which tells about real events and emphasizes expensive reconstructions, is positioned as an important strategic direction of the Ukrainian documentary. The focus on the entertainment of the viewer determines the specifics of its subject.

La polilla guatemalteca es considerada una plaga que afecta principalmente al tubérculo de la papa a nivel de cosecha y postcosecha, ocasiona pérdidas a gran escala de la producción y afecta económicamente al bolsillo de los agricultores, por su alto costo en el control químico. El presente artículo es una revisión bibliográfica sobre la resistencia a insecticidas que presenta la polilla guatemalteca Tecia solanivora y otros productos químicos utilizados en el cultivo de papa Solanum tuberosum, uno de los principales cultivos a nivel de Latinoamérica. Específicamente se analizaron investigaciones regionales, conceptos y métodos de control que se han empleado: se tomaron polillas de localidades de Colombia país con alta presencia poblacional de la plaga y se evaluó insecticidas que se usan para el control de la plaga a diferentes concentraciones. La investigación se basó en una metodología descriptiva sobre investigaciones propuestas respecto al tema de interés, donde se ha encontrado resistencia confirmada, en cada una de las poblaciones consideradas que han presentado susceptibilidad o resistencia en base a los resultados obtenidos. Se valoró la resistencia de Tecia solanivora ante los insecticidas: carbofurán, clorpirifos y permetrina, productos altamente tóxicos, de mayor uso dentro de la producción de papa ycon los cuales no se ha obtenido excelentes resultados en el control de la plaga, debido al uso excesivo e indiscriminado de los mismos. Los bioensayos se realizaron en todos los casos bajo condiciones de laboratorio, con productos que fueron usados en la región donde la plaga se encuentra presente a mayor escala, los productos químicos evaluados fueron utilizados en diferentes concentraciones, teniendo en cuenta la concentración letal media (CL50) medida con la cual el 50% de los organismos mueren en un período de exposición al producto. De igual manera se presenta otras formas de control para esta plaga y los productos químicos que se encuentran autorizados por la institución sanitaria encargada principalmente en nuestro país.

Ship technology, slavery, repatriation and air transportation: continuity and change
Authors: Adu-Gyamfi Samuel , Osei-Egyir Helena , Darkwa Benjamin Dompreh
Published: June 2023

The Trans-Atlantic Slave Trade, which occurred between the fifteenth and nineteenth centuries, displaced Africans and people of African descent into the New World. The trade affected and influenced several aspects of the world economy, boosting the economies of participating countries and creating what would become the African diaspora. While several elements of the trade have gained recognition in scholarship, ships, as the single most important medium of transportation for African slaves, have received little attention. We contribute to the discourse by placing ships at the center of discussion by highlighting the relevance and importance of this human and cargo carriage as a vehicle of slavery. We also paid attention to air transportation in the era of voluntary repatriation of people of African descent back to Africa for tourism, business and to pay homage to the motherland. We achieved these objectives through the use of written sources. These included books, journal articles and relevant sites and databases relating to the history of science, technology and slavery among others. The research highlights, among others, the following: the invention of ships has changed the course of world history. It has been the single most tremendous medium of transportation responsible for transporting millions of Africans into Europe and the New World creating the African Diaspora. The era of sailing and the cruise period have offered man the opportunity to navigate oceans and seas that were hitherto uncharted. It also ensured that trade relations between and among countries were solidified. Beginning in the XIV century when ships used rudders that ran on shallow waters, trade was organized on as small scale between countries. The fifteenth century became a significant date in the history of ship building as there was an improvement in sea faring and oceanic navigation. The double-ended ship gave way for full-rigged ships. An even greater milestone was achieved in the eighteenth century when the steam was invented. This period produced fast sailing ships which were less costly and it greatly influenced the triangular trade which had begun some two centuries earlier.
The nuances of the organizational preparation the electrification of the Kharkiv plant of the Russian Locomotive-building and Mechanical Society (1895–1896)

The transition to an electromechanical drive of equipment has become a new milestone in industrialization, which has led to significant: an increase in labor productivy and a decrease in the energy intensity of production processes. But on the Ukrainian lands of the Russian Empire, this innovation was not introduced until the mid-1890s, and only since that time the process of electrification of production at Ukrainian enterprises has been developed, however, with a simultaneous retain the steam-mechanical drive of equipment also. The Kharkiv plant of the Joint-Stock Company Russian Locomotive-building and Mechanical Society became the first enterprise not only in the Ukrainian provinces of the Russian Empire, but throughout the country, which used solely an electromechanical drive for all equipment. Taking into account this priority, the organizational preparation for the process of electrification of this enterprise also became the first experience in the country of introducing such an innovation, comparable, perhaps, only with the experience of switching from a mechanical to a steam-mechanical drive, which, however, was not studied in the Russian Empire. Simultaneously, the level of technical literacy of a part of the management of the Joint-Stock Company Russian Locomotive-building and Mechanical Society was not high enough to give a technical and economic assessment of the relevant innovations. Therefore, the organizational preparation for the electrification of the Kharkov plant of this Society was carried out without any clear methodological approaches, which in the discussion regarding the electrification scheme of the enterprise led to the replacement of the issue of choosing the best option from the most effective ones to the question of choosing the best one from the cheap ones. As a result, the Society's experts developed terms of reference for a compromise version of the electrification project, the essence of which was to install relatively new electrical equipment in terms of technical level, but operated according to an already outdated scheme, which made this electrification option neither efficient nor cheap, but politically acceptable for the entire leadership of Society. Eventually, it was possible to achieve the expected benefits from the electrification of the plant not from the implantation of the chosen scheme for its implementation, but by concluding strategic agreements with Siemens & Halske, according to which the Company's Management Board ensured it won the competition for the electrification of Society's enterprise at an affordable price, and Siemens & Halske, in turn, subsequently supplied the Company with its products at significant discounts.
Metal ornaments from the burial mound necropolis Chornyanka of the Bilozerka culture (11th–10th centuries BC)
Authors: Hoshko Tetiana
Published: June 2023

The flat cemetery near the village of Chornyanka, Kakhovka district, Kherson region, is one of the largest row grave fields of the Late Bronze Age archaeological culture of Bilozerka in the northern Black Sea region. The cultural and chronological location of the Chornyanka burial ground was determined on the basis of an analysis of the main features of the funerary constructions, ceremonies and equipment. The established date of its functioning is the 11th‒10th century BC. 24 graves were identified and investigated. Most contained grave goods: pottery, bone and bronze tools, jewellery of bronze, bone, agate, mother-of-pearl, chitin and glass. This paper presents the results of metallographic and X-ray spectral analysis of bronze jewellery from Chornyanka cemetery: pins, temple rings and earrings. It presents and describes the characteristic microstructures of the metal finds. In addition, the process of production of various metal objects was investigated. Several chemical and metallurgical groups stand out in the spectral analyses of metals from Chornianka: Сu-Sn; Сu-Sn-As; Сu-As(Sn) and possibly remelting. Correlation diagrams of the characteristic pairs of elements are also given. In all the analyses, arsenic is present in tenths of a per cent. There is also a stable presence of an impurity such as antimony, mostly in tenths of a per cent, with concentrations in two cases reaching whole per cent. This means that they were probably included in the original ores. Some scientists believe that this feature is characteristic of the metallurgy of the Greater Caucasus. The results are compared with similar analyses from another cemetery of the Bilozerka Culture – Shyroke. Despite the general similarity and tradition, it is possible to highlight some differences in metalworking in both Bilozerka cemeteries (Chornyanka and Shyroke). Jewellery was made not only by casting. It was also forged with the help of mandrels. In addition, some products were made by welding several metal strips. Most researchers pay attention to the influence of the cultures of the Northwest region on the Bilozerka culture. Metalworking is traditionally thought of as having a Volga-Urals orientation. In this article, we propose to take into account new data on the chemical composition of metal and technology, which testify to the contacts of the Bilozerka culture with the Caucasus.

Retrospective analysis of production of main active ingredients and assortment of disinfectants in Ukraine
Authors: Myronchuk V. O. , Peleno R. A.
Published: June 2023

There are practically no disinfectants on the market of veterinary drugs that fully meet the requirements. This is due to the significant diversity and peculiarity of the structure of microorganisms and their ability to form resistance during long-term use of the same disinfectants. This is one of the reasons for the active search for effective active substances, the development of new drugs, and their registration, contributing to quite intensive changes in the range of disinfectants on the market. The work aimed to analyze the production, determine the share of domestic and imported disinfectants, determine the main active substances, and the range of disinfectants registered in Ukraine. The research material was a list of disinfectants registered in Ukraine used in animal husbandry, veterinary and humane medicine, and the food industry. It was established that from 2018 to 2022, 66 domestic and imported disinfectants were registered in Ukraine. Imported disinfectants are produced mainly in Great Britain, France, Belgium, Spain, Germany, Israel, Slovenia, Denmark, and the Netherlands. From among domestic companies, PP “Kronos Agro”, LLC “BioTestLab”, LLC “SANFORT-P”, LLC “Brovapharma”, LLC “Ukrvetprompostach”, LLC “Ukrainian-Polish joint enterprise “ZVK”, LLC “VetAgro” are engaged in the production of disinfectants, LLC “Inter-Syntez”, LLC “Ukrainian Chemical Technologies LTD”, LLC “GREENPAKS”, LLC NVK “Globus”, LLC “Vetsyntez”, PF “Termit”, LLC “ABM-Trade”, LLC “Dezsystema”, LLC “Tandem-2002”, NVPP “DEZO” and LLC “UKRTEK KO”. It was determined that manufacturers often use chlorine and oxygen as active ingredients, and the number of products with one active ingredient is relatively insignificant. Most often, the active substance of modern disinfectants is quaternary ammonium salts in combination with aldehydes. Their number is 33.4 % of all registered means. This means combining QAS and acids and QAS and oxygen compounds takes 3.2 times less time. Means containing other combinations of active substances are from 1.5 to 4.6 %. It was established that the leader in the production of imported “cleansing probiotics” (PIP – Probiotics In Progress) is the British company “Ingenious Probiotics”, which produces 66.7 % of registered products. Three companies produce this kind of disinfectant in our country; their assortment includes 23 names, and the largest share belongs to the company “Sirion”.

Although teat disinfection before milking has advantages, some producers believe the use of disinfectants to be unprofitable compared to qualitative teat processing using warm water with skin drying using paper towels. The aim of the work was to compare the effect of pre-milking treatment of cows' udders with Oxy Foam and Pre-Dip on the reduction of mastitis pathogens on the skin of teats cows on large dairy farms. The study was conducted in the winter-spring period on two dairy plants with a stable-free range cow breeding system. In the first group of animals: the right anterior and the right posterior teats of the udder were processed using disinfectant Oxy Foam and the left anterior and the left posterior teats were washed using warm water (control). Pre-milking treatment of the studied teats using disinfectant included foam application, keeping it for 30 seconds, and further wiping dry using disposable paper towels. In the second group of animals: the right teats were treated with Pre-Dip with the help of a cup by immersion with a subsequent exposure of 15 seconds. Swish from the skin of udder teats were taken using sterile tampons before the processing before milking and repeatedly after the end of the milking process. The ordinary treatment using warm water and drying using paper towels was found to reduce the number of microorganisms on the teat skin by 2.5 times (Р ≤ 0.001), while the use of disinfectant Oxy Foam –  by 6.4 times (Р ≤ 0.001), and Pre-Dip – 4.8 times (Р ≤ 0.001). Herewith, treatment with water reduced the amount of hemolytic staphylococci on the teat skin – by 1.9 times (Р ≤ 0.01), disinfection using Oxy Foam – by 4.4 times (Р ≤ 0.001) to 13.2 ± 3.14 CFU/cm3 of the wash, and with Pre-Dip – 4 times (Р ≤ 0.001) to 14.6 ± 3.05 CFU/cm3 of wash. After using warm water, the number of pathogenic streptococcus reduced by 1.8 times (Р ≤ 0.01), and by 2.5 times (Р ≤ 0.001), when using Oxy Foam and Pre-Dip – 2.1 times (Р ≤ 0.001) to 7.5–8.9 CFU/cm3 of the wash. Microorganisms of Escherichia kind were well-removed with the use of ordinary -pre-milking treatment and were distinguished from the cow teat skin in single cases in the number of only a few cultures. Therefore, Oxy Foam based on hydrogen peroxide and lactic acid turned out to be a more effective means for treating the udder of cows before milking, compared to Pre-Dip with a content of 0.15 % of free iodine. Further research will be aimed at creating new domestic ecologically safe means for the pre-milking treatment of cow udders.
Revuelta y resistencia: Indígenas, ciudadanía mestiza y Estado en la movilización social de octubre de 2019 en Ecuador
Authors: Narváez Collaguazo Roberto Esteban
Published: June 2023

En octubre de 2019, el rechazo a la política económica en Ecuador impulsó la movilización de organizaciones indígenas y de otros segmentos poblacionales. El Gobierno promovió procesos judiciales contra indígenas, estudiantes y trabajadores, quienes fueron detenidos y procesados penalmente, acusados de actos terroristas. La defensa de los procesados solicitó las consideraciones de interculturalidad que el caso ameritaba, a través de una pericia de antropología cultural que permitiese comprender los elementos implícitos en los hechos relacionados con el proceso penal por sabotaje y terrorismo. El artículo aporta con un análisis antropológico, en el contexto del proceso judicial, desde una mirada etnográfica, cuya interpretación se ancla en los elementos históricos y sociales analizados, que exponen un vínculo entre la construcción y reconstrucción de la etnicidad indígena y el rechazo a políticas públicas que afectan a la economía de la población de bajos ingresos económicos.
El derecho a la participación política de pueblos y nacionalidades en la Ley de Aguas de 2014
Authors: Michilena Proaño Sylvia Paola
Published: June 2023

El presente artículo busca situar la importancia de una estrategia de descorporativismo llevada a cabo por sujetos sociales inscritos en el marco del Estado de derecho —promulgado en la Constitución política de Ecuador de 2008— bajo el marco explicativo del populismo, para pasar a ubicar a los sujetos de derechos colectivos, en este caso el movimiento indígena ecuatoriano con su demanda de gestión comunitaria del agua, anunciada como un problema público que forma parte de la elaboración de la nueva Ley de Aguas (2014). Es decir, se busca explicar el corporativismo que ejercen diversos actores sociales en sus formas de participación política en el Estado, a la que dotan de un contenido gremial y económico que considera las partes sobre el todo. Entonces, lo que habría de tener cabida primero es un descorporativismo eficiente, para posteriormente articular un Estado plurinacional, o de derechos.

The cost of feed is the largest proportion in raising livestock. This study aims to determine the effect of the administration of fermented kepok banana stem waste using eco enzymes as an alternative feed on local sheep. This research was conducted at Alvino Farm in September - December 2022. The design used was completely randomized (RAL) with four treatments and five replications so that 20 experimental units were obtained. The sheep used were 20 local sheep with an initial weight of 19.65 ± 1 kg. The treatments given were P0 (80% field grass + 20% concentrate without fermented banana stems), P1 (70% field grass + 20% concentrate + 10% fermented banana stems), P2 (60% field grass + 20% concentrate + 20 % fermented banana stems), and P3 (50% field grass + 20% concentrate + 30% fermented banana stems). The parameters studied were final weight, slaughter weight, empty body weight, carcass weight, and carcass percentage. The results showed that the provision of fermented banana stems up to a level of 30%  improve empty body weight.  However, it do not improve final weight, slaughter weight, carcass weight, and carcass percentage.
Could Information About Honey Fraud Increase Consumers’ Valuation of Domestic Honey in the Face of Rising Honey Imports in the U.S. and EU?
Authors: Gustafson Christopher , Champetier Antoine
Published: June 2023

The consumption of honey, which has been sought out by humans for use as food and medicine for thousands of years, has been increasing in recent decades with rising incomes and attention paid to food choices and health. In two decades, honey consumption in the U.S. has risen from 1.2 pound per capita per year to 1.9 in 2021. In the European Union, per capita consumption rose from 1.5 to 2.1 pounds per capita over the same period. While this might appear to be a boon for U.S. and EU beekeepers, honey is a heavily traded product, and imports from large producers such as Argentina, China, Brazil, or India have captured much of the demand growth on U.S. and European honey markets. The two regions are now the two largest importers of honey globally, with 20% of all traded honey going to the U.S. and 40% to the EU, according to the United Nations Food and Agriculture Organization’s trade data for 2015-2020. The figures below show that imported quantities have grown to surpass domestic production in both regions. In the United States, from where exports are small, over 60% of honey available for consumption is imported. Trade and production figures in value terms confirm the growing presence of imports in the two markets but also reflect the fact that imports are more often used in manufactured products and fetch lower prices than domestic honeys on average. International trade increases the variety of products available and lowers the prices for consumer products. However, for certain food items, including honey, consumers face a risk that imported products have been purposefully adulterated—predominantly with low-cost alternative sweeteners—and/or mislabeled.
Gold Exchange Traded Funds (ETFs), Take Profit / Stop Loss Prediction using Machine Learning
Authors: Shawky Tamer

Investment vehicles called Gold-Traded Funds (ETFs) try to follow the price of gold and are traded on stock markets. Without having to actually buy or store the metal, they provide investors with access to gold. Like stocks, gold ETF shares may be purchased and sold. Stop loss and take profit are common risk-management techniques for trading and investing that are automatically generated when the price of an asset rises above or below a certain threshold. Stop loss orders are used to minimize possible losses by closing out a trade before the price falls any lower. All earlier mentions combined; Our research showed that in order for an investor to get the maximum profit or the smallest loss, the movement of the points used to halt a loss or take gains must be adjusted. In our study, we used a series of algorithms to anticipate the market's direction and the progress in that direction. The points were adjusted automatically based on the outcomes. This study demonstrates how to establish an easy-to-use machine-learning model that aims to forecast the gold market, Stop Losses and take profit. We shall predict market trends to determine stop loss or take profit pips based on supervised machine learning models. Yahoo Finance released the dataset that was utilized to forecast market trends and (Stop Loss / Take Profit) Pips. Tree, Support Vector Classifier (SVM), random forest, Neural Network and K-Nearest Neighbour (KNN) Classifier are used with an accuracy of 83%,56%,91%,99% and 92% in sequential.
