EXACERBATION OF ORAL LICHEN PLANUS: IS IT THE SIGN OF SYSTEMIC COMPLICATION?
Authors: Rambe Sarinah , Paramita Felicia , Wulandari Endah Ayu Tri , Rahmayanti Febrina
Published: November 2022

Oral lichen planus (OLP) is a chronic inflammatory mucocutaneous disease with periods of remission and exacerbation. A 23-year-old male came to Oral Medicine clinic, Cipto Mangunkusumo General Hospital (RSCM) with complaint of painful sore mouth in the oral cavity. Previously in 2019 the patient was diagnosed with erosive oral lichen planus and was absent for follow-up for almost 2 years. The patient also had a history of hematologic disorder with indefinite diagnosis. Intra oral examination showed sloughing, erosion, atrophic and hyperkeratosis at several locations in oral mucosa. The diagnosis was OLP with the differential diagnosis being discoid or systemic lupus erythematosus and other bullous diseases. He was then prescribed corticosteroid swish and spit and an antioxidant supplement. The patient was referred to hematology-oncologist for hematologic pathology and diagnosed as suspected polycythemia, but definitive diagnosis cannot be obtained due to patient’s refusal for bone marrow puncture. The change of OLP type within 2 years and the presence of suspected polycythemia is a matter of concern. The exacerbation of OLP should alarm clinicians for the possibility of systemic involvement. Thus, deep exploration and multidisciplinary collaboration are critically needed in the management of OLP.

Published: November 2022

Nanotechnology is the study of materials associated with components which are less than 1 to 100 nanometer .[1]The word (NANO) is derived from the greek word nanos which means dwarf which symbolises the word ‘Billionth’.It explains that a nanoparticle(10-9 )m is billion times smaller than a normal macro scale particle .These nano size particles cannot be viewed under ordinary microscope they need specialised high resolution microcopic devices devices to view them. The word nanotechnology was a controversy in the last centuries ,as it was not used in various fields in our life but nowadays it is evident that it is being used in several fields and also having various applications especaially in the field of dentistry. This usage is due its advantages that shows the good working of nanotechnolgy in nanoscales than in usual micro or macro scales .Due to its nano size it is expected to have various properties than normal particles because of its greater surface area . In denistry these nanoparticles has been started to be used to prepare more useful efficient materials and several devices These Nanoparticles have many advantages in dental field, such as (i) storing capacity and good stability in dental fluids , (ii) preparation methods are getting easier, (iii) easier large-scale manufacturing, (iv) Area specific controlled or timed release. Nowadays ,nanoparticles satisfy the needs of dentistry in deliver of medicated drug directly to diseased site , for example in to the gingival pocket or dento-gingival pouch /sac and also have controlled timely release of drugs.

Published: November 2022

The stir-squeeze casting technique generally alters a material’s physical and mechanical properties. This research investigates the effect of adding fly ash and alumina to the stir-squeeze casting of old aluminum cans. The stir-squeeze casting research parameters were carried out at a pouring temperature of 750oC with a stirring speed of 350 rpm for 3 minutes, with pressure variations ranging from 6 MPa, 8 MPa, and 10 MPa to fabricate Aluminum Matrix Composites (AMC) with an alumina weight fraction of 15% and fly ash of 12%. Aluminum Matrix Composites are metal matrix composites that use alumina and fly ash as reinforcing components. AMC development has also shown promise, owing to good mechanical qualities such as high hardness, impact strength, and relatively easy-to-find basic materials. On composites, X-Ray Fluorescence (XRF) testing or chemical composition testing, X-Ray Diffraction (XRD), impact strength Brinell hardness, and Scanning Electron Microscope (SEM) was performed; the test results obtained the highest value of the highest hardness at the bottom, and on composites were obtained at a pressure of 6 MPa at 1.577 gr/cm3 and 0.577 percent, the highest impact value at

Authors: Arief Alkahfi  , Pratiwi Diah Kusuma
Published: November 2022

Most of Indonesia's land is covered in swamps, and many infrastructure projects, including bridge construction, factory construction, and pipe installation, are completed in swampy environments. Swamp water typically has a high acid content and higher than normal concentrations of sulfates and chlorides, which are known to be more active in producing corrosion under normal conditions. This study aims to analyze and understand the corrosion rate and changes in the physical and mechanical properties of ASTM A36 steel that has undergone quenching heat treatment. Compared to steel ASTM A36 as received immersion in corrosive media using swamp water from The Village of Rambutan, South Sumatra Province, which has a pH of 3.00 with variations in immersion time of 48 hours, 96 hours, and 144 hours. The method used to determine the hardness value was the Brinell method, the corrosion rate was determined by the weight loss method, and SEM tests were carried out to determine the surface morphology of the specimens after immersion and XRD tests. The results showed that ASTM A36 steel specimens with quenching heat treatment had a higher hardness value than the as-received specimens; the greatest value was obtained in specimens with quenching treatment with immersion time. 48 hours, which is 497.97 BHN. The immersion test results showed that the highest corrosion rate occurred in the as-received specimen with a 144-hour immersion time of 17.6 mpy. Observation of the microstructure on the surface of the specimen found uniform corrosion and fitting corrosion; this was evidenced by the detection of iron oxide (Fe2O3), known as iron rust which is brownish-yellow in XRD testing.

Authors: NOSACH Nataliia
Published: November 2022

Management of the enterprise in modern conditions requires a comprehensive solution to many problems caused by both external and internal factors. The effectiveness of the enterprise management system is the ability to anticipate the economic and commercial situation, prevent the negative impact of internal and external factors, take measures to minimize costs, ensure the achievement of goals and above all get a positive financial result - the desired profit. These circumstances require the formation of new approaches to management and tools for their application. Controlling is such a tool today. The ability to make timely, sound, and rational strategic and operational decisions, coordination of the functioning of structural units of the enterprise is the basis for the introduction of controlling tools in enterprises. To realize such opportunities, it is necessary to ensure the regular receipt of accurate and reliable information about the processes taking place in enterprises, about deviations from the planned indicators provided by the controlling system and its tools. These methods of controlling can be said to be used in practice in the work of the enterprise - at the intuitive level. and for the company the consequences of the decisions made will become even clearer. It is determined that the tools also depend on the period of activity of the enterprise - operational or strategic. As a result of the study, a classification of controlling tools was proposed. The basis for the practical use of the controlling system is its understanding as a process of rational management using specific ways to influence the activities of enterprises, to identify the most promising areas of development.

Published: November 2022

The terminological basis of investment management is considered in the article, the approaches of scientists to the interpretation of the term "investment" are defined and generalized. The article presents the views of various scholars on the interpretation of the term "investment", so most authors understand investment as investing capital in all its forms in various objects (instruments) of its economic activity for profit and other economic or social effects, implementation of which is based on market principles and is related to factors of time, risk and liquidity. Based on the existing approaches, the proposed definition of investment is a set of all values that are invested in various objects of business and other activities in order to increase them and / or achieve a certain goal (effect). The article presents the interpretation of investments by the following groups: the totality of all types of values, investment of capital / resources / money, the method of capital allocation, the cost of creation. The classification of investments is carried out and the main features of classifications of investments are analyzed. It is established that the institutional structures of most countries lag far behind the pace of digitalization of markets and therefore cannot fully perform their regulatory functions, which creates a chaotic development of both markets and the main instruments of such markets. It is noted that money laundering and the implementation of shadow capital schemes are only a part of illegal transactions through the use of cryptocurrencies and other financial instruments. Prospects for further research in the subject area are identified.
Keywords: investments, classification of investments, tools, theoretical bases, digital economy.

Published: November 2022

The article presents the study of the current state of the logistics sector of Ukraine, its problems and prospects for development. Based on the collected statistics, conclusions were made about the situation of the logistics market, the problems it faces and possible directions for further development. The purpose of the study is to show the situation of the modern logistics sector, its problems, as well as prospects for development by analyzing logistics expenditures, the share of export-import logistics services, and the positions of Ukraine in the rate of Logistic Performance Index. From the point of view of transport and logistics, Ukraine occupies a favorable geographical position, as its powerful transport potential takes into account road, rail, sea, river, air and pipeline transport. However, from the viewpoint of the global logistics market, Ukraine continues to be at a disadvantage, yielding to Western countries in conducting international trade in terms of logistics services. Such difference between the favorable geographical location and the insufficiently high level of development of the logistics system does not allow Ukraine to take a leading place in the global economy. In addition, in the context of globalization of international markets and expansion of economic development, the logistics sector of Ukraine needs more and more attention. Hence, only effective solutions can improve the situation. Otherwise, Ukraine risks to get into crisis. Problems of international transport and logistics systems functioning are revealed and the ways to improve the market of logistics services in Ukraine are proposed. Thus, it is more important nowadays to analyze the problems of this sector taking into consideration independent data and identify its prospects.
Keywords: logistics sector, logistics market problems, global logistics market, import-export, logistics services.
AN UNORTHODOX VIEW OF RURAL DEVELOPMENT
Authors: SHIBAEVA Natalia , BABAN Tetiana
Published: November 2022

The article identifies the role of agricultural enterprises, rural communities, and the state in the development of rural areas of Ukraine.
The author gives her vision of the category “rural areas” for this study and summarizes the functions inherent in rural areas. This paper determines the integrated function of rural areas, which is to create a spatial basis for comfortable living, economic activity, preservation, and enhancement of bio- and landscape diversity.
The article analyzes the main indicators of activity of agricultural enterprises, indicators of agricultural development, and socioeconomic indicators of the level and quality of life of rural residents. It is determined that the positive dynamics of agricultural production in Ukraine is not accompanied with a corresponding improvement in living standards of rural residents. It is concluded that it is necessary to modify the role of agricultural enterprises through compliance with the principles of sustainable development while maximizing their target functions.
The paper examines the participation of the state and united territorial communities (UTC) in rural development. It is outlined that in Ukraine support for rural development at the state level is carried out mainly based on a sectoral approach in the presence of elements of a territorial approach. Such elements include the financing of infrastructure projects in rural areas. Decentralization in the country has strengthened the role of UTC in rural development. The paper identifies the advantages and challenges faced by UTC in the process of rural development planning.
The importance of maintaining the advantages of rural areas is substantiated. It is emphasized that the development of rural infrastructure, the improvement of its ecological condition is possible with the common efforts of the state, local governments, and enterprises.
Keywords: rural areas, rurbanization, decentralization, agricultural enterprises, sustainable development.

Плацента, Placenta – це комплекс тканинних утворень, які мають розвиток з судинної оболонки плода та  слизової оболонки матки для зв’язку плода з материнським організмом. Плацента це орган , який забезпечує організм плода киснем, поживними речовинами. Вона перероблює поживні речовини материнського організму ( гемоглобін, білки, вуглеводи) та синтезує нові.  В плаценті синтезується біологічно активні речовини, які мають великий вплив на перебіг вагітності, розвиток плода, а у подальшому і на розвиток новонародженого. Плацента у всіх ссавців відіграє дуже важливу роль, а саме забезпечує зв'язок ембріону з материнським організмом. Плацента формується тільки в період вагітності, а важливу роль  у її формуванні відіграють - судинна оболонка плоду та слизова оболонка матки.  Плацента у кожного виду тварин має свої певні особливості: по-перше, це форма та розмір ділянок контакту судинної оболонки ембріону з тканинами матки самиці; по-друге, рівень розгалуження судинної оболонки ембріону в тканинах матки та її заглиблення в оточуючі тканини матки.  

За період вагітності матка значно збільшує свої розміри та вагу, за даними фахівців таке збільшення знаходиться в межах 10-20 разів. Плацента є основним органом завдяки якому ембріон отримує поживні  речовини для подальшого росту та розвитку, а також отримує захист від чинників зовнішнього середовища. Від маси та розвитку плаценти залежить також і ступінь розвитку новонародженого молодняку та здатність пристосування до зовнішнього середовища.

Маса плаценти та кількість в ній котіледонів залежить від віку вагітної тварини та маси теляти при народженні. В середньому у корів віком 6-8  років та  масі теляти 27-30 кг маса плаценти складає 18,20 ± 2,10 кг, це більше ніж у віці 3-6 років на 22%, збільшується також і кількість котіледонів на 20%. Маса плаценти у свиней породи велика біла збільшується поступово з віком тварини і досягає максимальної маси при 2-3 опоросі. Поступово до 5-6 опоросу маса її знижується, що має негативний вплив на кількість приплоду та розвиток поросят. Зміна маси плаценти може бути пов’язана з поступовим згасанням впливу гормональної регуляції на  рівень обміну речовин, дією стрес факторів та в зв’язку з перенесеними захворюваннями.

The Perception of Snack Healthiness and Preferences in Children is Related to Health Parameter Measures
Authors: Althubaiti Heba
Published: November 2022

The relationship between snack preferences/healthiness and health parameters is still poorly defined. Most children choose snacks low in nutritional value, which may contribute to the rise in childhood obesity. This study has examined children’s snack preferences and healthiness by age and gender and correlated them with their health parameters. Scottish Nursery and Primary children aged 3–12 years (n = 472) performed snack card sorting exercises in which they were presented with 18 different colored snack images, which counted as one portion, followed by two main snack questions related to snack healthiness and preferences. Health parameters were measured. Older children were better able to determine which snacks were healthier based on their energy content. Children with a higher body mass index percentile were not found to have a specific preference for unhealthy snacks based on the four nutritional components. However, snacks high in fat and sugar (and low in energy and salt) were preferred by children with higher body fat. A positive relationship was observed between the energy content of the children’s top five snacks selected for healthiness and their weight, waist circumference, hip circumference, waist-to-hip ratio, and waist-to-height ratio. There was only a negative relationship with height and body fat. The relationship between children’s perceptions of snack preferences and healthiness and their health parameters is still unclear and needs further investigation.

Published: November 2022

La enfermedad asociada al biofilm está siendo evaluada con profundidad en diferentes campos de la Microbiología Clínica, en tanto que representa un importante problema de salud pública. La formación de biofilms constituye un modo de crecimiento que hace que las células que lo forman sean menos susceptibles a los antimicrobianos y a la acción del sistema inmune del huésped y, permite que los patógenos sobrevivan en entornos hostiles, se dispersen y colonicen nuevos nichos no previstos. En lo relativo a la infección fúngica de gravedad, aún hoy constituye un gran reto para la salud pública por su elevada morbi-mortalidad a pesar de los avances en diagnóstico y estrategias de tratamiento. Para avanzar en el conocimiento de los procesos que motivan la invasión fúngica, los modelos in vitro de biofilm constituyen una herramienta interesante para hallar respuestas que puedan trasladarse y aplicarse en la práctica clínica. En el laboratorio de Referencia e Investigación en Micología, del CNM-ISCIII mantenemos una línea de investigación, utilizando un modelo de biofilm de Aspergillus fumigatus, y cepas de diferentes orígenes y fondos genéticos, que nos ayudarán a desarrollar herramientas complementarias para establecer nuevos test diagnósticos y estrategias de tratamiento, así como relacionar resistencia con la capacidad de formar biofilms y con la patogenia y virulencia del hongo. En este estudio se analiza fenotípicamente esta estructura mediante técnicas de imagen basadas en microscopia de fluorescencia con marcajes específicos para evaluar la arquitectura del biofilm intraespecie y el efecto de factores que puedan alterar su desarrollo e integridad.

Oblidens bornholmensis, known from isolated upper posterior (palatine) and lower posterior (mandibular) tooth plates, was the first myriacanthid holocephalian to be described from the Hasle Formation (Pliensbachian, Early Jurassic) of Bornholm (Denmark). Further collecting in the Hasle Formation has yielded seven more specimens of myriacanthid tooth plates. Two mandibular tooth plates are assigned to Myriacanthus paradoxus, thereby extending both the geographical and stratigraphic range of the genus. In addition to new material of Oblidens bornholmensis, some distinctive myriacanthid palatine and mandibular tooth plates are described and left in open nomenclature. The Early Pliensbachian deposits of Bornholm preserve the most diverse myriacanthid fauna known to date.

En escenarios de emergencia usualmente es difícil contar con una infraestructura de red, especialmente en lugares remotos o geográficamente complicados por el difícil acceso. Sin embargo, es necesario disponer de herramientas para comunicarse o realizar una valoración de la situación. En este sentido, las redes ad hoc surgen como una opción para solucionar esta problemática. En el presente artículo se propone el desarrollo de un sistema de comunicación de emergencia para la transmisión de tráfico multimedia en un escenario real, entre los diferentes pisos de un edificio. Para tal objetivo, se realizaron múltiples experimentos para determinar los valores de métricas fundamentales (v.g. packet loss, delay y throughput) para la transmisión de audio y video en tiempo real. En concreto, se desarrollaron herramientas de código abierto con capacidad de extraer las métricas requeridas y comparar de forma objetiva la calidad del video empleando mecanismos de codificación actuales (v.g. VP8, VP9, H.264, H.265). Los resultados obtenidos muestran que VP8 es el códec más adecuado para el escenario propuesto. Además, se desarrolló una herramienta de videoconferencia con capacidad de adaptar las características del video (v.g. bitrate) acorde a las condiciones de la red.

Authors: Córdova Paúl , Tobar Andrés
Published: November 2022

La movilidad humana hacia Ecuador ha sido una temática en creciente difusión en la coyuntura actual, por las condiciones post pandemia que atraviesa el país. En tal motivo, este artículo examina la información concerniente a los ciudadanos que han recibido su visado por parte del Ministerio de Relaciones Exteriores y Movilidad Humana. Con base en los datos disponibles, el análisis se ha enfocado en los solicitantes que se encuentran en territorio nacional provenientes de Colombia y Venezuela. Se han empleado dos modelos de aprendizaje automático con la finalidad de destacar y validar una posible relación entre las características socioeconómicas de los ciudadanos con respeto a su categoría migratoria; identificando si variables como la edad, género, estado civil y nacionalidad pueden influir en la solicitud de visado respecto al tipo de residencia. Según los hallazgos encontrados, ciudadanos colombianos solteros independiente de su edad optan por una residencia temporal; mientras que, para el caso de los divorciados, por una residencia permanente. Para los ciudadanos venezolanos solteros con una edad menor a 23 años la mayoría posee una residencia permanente; no obstante, aquellos con una edad mayor acceden a una residencia temporal.

En la agricultura, el agua es vital para el cultivo. Conocer cuándo regar y cuánto regar se puede responder técnicamente, a partir de datos provistos por estaciones meteorológicas. Estos datos no siempre están disponibles. Además, si bien en el mercado existen controladores de riego, estos no están integrados a las estaciones y son de arquitectura cerrada. Por otro lado, el desarrollo de la electrónica, la disponibilidad de sensores de costo asequible, protocolos, estándares y código abierto, facilitan la integración de componentes de hardware y software.  Este trabajo propone un prototipo de estación meteorológica inteligente que provee en tiempo real datos de temperatura, humedad del ambiente, humedad del suelo, lluvia, como entrada para que un controlador active el riego en dos casos: i) por necesidad de agua para el desarrollo del cultivo; o ii) para mitigar heladas, apoyando al desarrollo sostenible agrícola con tecnología local, de código abierto y de costo asequible. Se aplicó la metodología basada en prototipos rápidos, evaluando la operatividad de cada dispositivo electrónico y su integración en ambiente controlado, y luego en una parcela experimental, en la granja Nero de la Universidad de Cuenca. Para el desarrollo se empleó hardware y software de código abierto, utilizando IDE de Arduino y Visual Studio Code. Para energizar se usó un panel solar y baterías, optimizando el consumo energético. Este prototipo ha mostrado un funcionamiento continuo y estable, operando a 3100 m.s.n.m. Se continuará monitoreando y mejorando, para en el futuro poner a disposición de usuario final.

La industrialización y el rápido crecimiento de zonas urbanas aumentan alarmantemente la presencia de contaminantes atmosféricos. Estos contaminantes afectan la calidad de vida de las personas y se crea una oportunidad de estudio para determinar su comportamiento atmosférico y la relación entre variables meteorológicas presentes en el ambiente. Previo a esto, se aplicaron ventanas rodantes de tiempo para eliminar datos anómalos. A continuación, se identificaron variables y se segmentaron los datos a través del algoritmo X-means. También, dos clústeres que representan las relaciones entre pares de variables y la temporalidad de las ventanas de tiempo. Como resultado, se encontró una correlación inversa de -0,78 entre las variables de ozono y punto de rocío dentro de las horas de la jornada laboral.
Diagramas de estados para la conversión del protocolo MQTT-SN a MQTT utilizando UML
Authors: Panchi Carlos , Egas Acosta Carlos
Published: November 2022

Las implementaciones del convertidor de protocolos MQTT-SN a MQTT han considerado que MQTT-SN opera sobre capa de red. En redes inalámbricas de sensores con topología lineal, existe una sola ruta y los nodos inalámbricos tienen una única interface, por lo tanto, no serían necesarios protocolos de enrutamiento. En este artículo se presenta el diagrama de estados del convertidor de protocolos para ser utilizado en una red con MQTT-SN encapsulado en capa de enlace como un insumo para su posterior implementación. Para desarrollar el diagrama de estados se utilizó la metodología del lenguaje de modelado unificado, los diagramas de estados contienen procesos que permiten la codificación del convertidor de protocolos. Se realizó una revisión teórica y funcional de los protocolos MQTT y MQTT-SN para conocer los mensajes incluidos en cada uno, así como de los campos de mensaje que interactúan en el proceso de conversión. El evento asociado con la llegada de mensajes al convertidor, activan los cambios de estados y desencadena una serie de procesos que concluyen en la generación de un mensaje convertido. Para encontrar inconsistencias o solucionar problemas de lógica en los estados y procesos obtenidos en el diagrama de estados, se utilizó la herramienta UPPAAL.

Технологические приемы выравнивания поля температур в помещении
Authors: Толстов Сергей , Панченко Сергей
Published: November 2022

Необходимым требованием для жизни человека и выполнения им своих профессиональных обязанностей является обеспечение определенного температурного режима в помещении. Этот режим обеспечивается системой отопления. В настоящее время традиционным способом обогрева как жилых, так и производственных помещений остается обогрев при помощи радиаторов отопления. В этом случае теплота от теплоотдающей поверхности радиатора передается окружающему воздуху в помещении путем теплоотдачи. В результате температура воздуха по объему помещения распределяется неравномерно. Причем, что особенно значимо, более теплый воздух, как более легкий, скапливается вверху у потолка, а холодный, как более тяжелый, опускается вниз, к полу. Человек в таком случае находится в неблагоприятных температурных условиях. Поэтому поиск решений, позволяющих более равномерно распределить температурное поле по объему помещения, является актуальной задачей. В работе предлагается технический вариант, позволяющий решить данную проблему. Апробация предлагаемого способа дала определенный положительный результат и показала возможность выравнивания поля температур в помещении.

FROM RITUAL TO ROMANCE: AN ETHNOCENTRIC READING OF SOME TRIBAL FOLKLORE OF SOUTH GUJARAT REGION
Authors: Joshi Jagdish , Hariyani Neha
Published: November 2022

A study of any culture may involve its anthropological roots, genealogy of the families, its taboos and the gradual being and becoming of the culture group. The paper tries to study the ethnicity of the tribal natives of the South Gujarat, located in the Western part of India, through its folklores as the study of folklores is one of the impetuses all over the globe and is a remarkable component of identity formation. These tribal communities flourished since six hundred years and gradually the acid of modernity, acculturation and assimilation have washed away their past tribal originality, but if we minutely observe their culture, their residues remain in their rituals, in their religiosity, in their communal life in some form or other. The paper is an attempt to bring to the limelight the rich cultural heritage from ritual to romance in the tribals of south Gujarat through their folk songs, tales, riddles, and dances, which contributes to the enrichment of the Indian culture.
