EFFECT OF CROSS-COUPLING ON STABILITY MARGIN OF GYROVERTICAL PLATFORM AND DECOUPLING METHOD
Authors:   Le Quy Don Technical University, Hoang Manh Tuong
Published: May 2023

The paper investigates the effect of cross-couplings in gyrovertical platform and proposes a method to decouple. The gyroplatform uses two gyroscopes whose axial precession is perpendicular to the respective axis of platform and has an angular momentum vector in opposite directions. This layout will reduce the influence of the rotation of gyro motors. However, between the gyroplatform channels there appears cross-coupling that reduces the stability of system stabilization. The simulation results show effect of cross-couplings on the stability and method to overcome these problems.

The Glucagon-Like Peptide-1 Analogues therapy in the non-diabetic patients
Authors: Sienicka Agnieszka , Kubasik Krzysztof , Pisula Agata
Published: May 2023

Glucagon like peptide-1 (GLP-1) receptor agonists are a group of hypoglycemic drugs that are used primarily to treat type 2 diabetes both as monotherapy and in combination with other antidiabetic drugs. In contrast to most hypoglycemic drugs, GLP-1 receptor agonists not only do not cause weight gain, but can even lead to weight reduction. This is why they are recently also increasingly used in the treatment of obesity in patients without type 2 diabetes. Current research indicate that liraglutide and semaglutide are effective and safe methods of treatment for overweight and obesity in patients without diabetes. GLP-1 receptor agonists’ mechanism of action is related to the incretin system. They lowers glucose concentrations by increasing insulin secretion and suppressing glucagon release. Moreover, they cause a retardation of gastric emptying and affect the central nervous system, resulting in a decrease in appetite and stimulation of satiety. In addition, a rising number of research studies show that GLP-1 receptor agonists may also have beneficial effects in the treatment of other conditions, such as nervous and cardiovascular diseases, metabolic diseases or endocrine disorders. Due to the new findings, even more research should be carried out to further investigate and describe the multidirectional effects of these drugs.

Authors: Mohammed Falah Saleh , Uysal İmran , Sevindik Mustafa
Published: May 2023

The treatment of microbial infections has proven challenging for humans in recent years. Synthetic medications, such as antimicrobial agents, are used for treating these infections. Antimicrobials derived from natural sources have gained popularity as an alternative to manufactured medications due to their lack of adverse effects. Plants, which play a significant role in this setting, have historically served as a reliable natural defence against several pathogens. In this study, studies on plants used against viral diseases are mentioned. Studies on viruses that cause disease have been compiled in the literature. According to the findings, it has been reported in the literature that many different plant species are effective against herpes simplex virus (HSV-1, HSV-2), human immunodeficiency virus (HIV), influenza virus (A, B) and parainfluenza, Poliovirus, Astrovirus, Parvovirus, Sindbis virus (SINV), Feline calicivirus (FCV), Rhinovirus, Echovirus, Rotavirus, Bovine alphaherpesvirus 1 (BoHV-1), Reovirus, Vaccinia virus (VACV), Cardiovirus A (Encephalomyocarditis virus; EMCV), Coxsackie virus, Semliki forest, Measles virus, Newcastle disease virus (NDV), Coronavirus, Adenovirus (ADV-3, ADV-5, ADV-8, ADV -11), Canine distemper virus (CDV), Lumpy skin disease virus (LSDV), Hepatitis A, B, C virus and Enterovirus. To combat viruses, plants can be considered a potentially invaluable natural resource.

Democratisation and Conflict in Nigeria
Authors: Ahmed Iyanda Kamoru , Adjah Adjah Ekwang
Published: May 2023

This paper discusses Democratisation And Conflict In Nigeria. The contemporary history of Nigeria is a tale of internecine conflicts and economic woes. The post-independence vision of Nigeria as a giant of Africa primed to take off into sustained development and democracy has long evaporated. Four decades of nation-building appear to have availed veiy1ittle. Rather than greater integration, there has been, across the nation, a succession of ethnic/religious conflicts, with monumental human ‘casualties and tragedies in their wake. Consequently, various views and strategies are currently being canvassed for peace and ethnic/religious conflict management in a democratic Nigeria. In a plural society like Nigeria, conflicts have been more associated with economic, religious, political, ethnic and communal issues. The surge and spate of such conflicts in Nigeria since the return of democratic dispensation, and their unprecedented spread, longevity and intensity have greatly complicated the political, social, economic and environmental problems of the country. Violent conflict threatens everything, including lives, property, development, democracy, and the viability and sustainability of our nation-state. Thus, the need to resolve conflicts in Nigeria is urgent. This chapter is, therefore, an attempt to contribute to the current debate • on civil society and ethnic/religious conflict management in a democratic Nigeria.
Implementation of Lean Manufacturing to Identify and Minimize Waste in The Welding Framebody Department of PT XYZ
Authors: Awanis Anggita , Vikaliana Resista
Published: May 2023

PT XYZ is a transportation equipment manufacturing company that must always maintain that the products it produces can achieve sales targets. However, in carrying out the production process, PT XYZ often experiences shortages in the production process, one of which is due to problems in the welding frame body department.  Thus, the objectives of this research are to determine the flow of the production process in the welding frame body department, then analyze the waste that occurs in the body parts of the welding frame. This frame body welding department has a production process flow starting from St. Rear Frame 1 to St. Rear Frame 4, then St. Front Frame 1 to St. Front Frame 3, after that St. General Assy, Permanent Robot/Robot Handling, Fine Boring, Manual 1 and Manual 2, and ending in Tapping and Numbering. Based on the flow of the production process, it was found that St. Rear Frame 3 is the most problematic with a percentage of 21%. By using the DMAIC method, in the Define stage, it was found that the most common problem that occurred in St. Rear Frame 3 was a torn pipe in lower jig B with a percentage of 6%. At the Define stage, it is also known that the root cause of the problem is the lack of accuracy from the operator, who may be sleepy at work due to lack of rest, or even chatting, which results in setting teaching too far because it is more dominant to the lower, not to the iron connection between the lower and the subframe. Then, at the measurement stage, the target is to reduce 6% of the problems to 4%. Furthermore, at the analysis stage, an analysis is carried out to determine if the potential problem occurs and then what next steps will be conducted which is useful for minimizing waste. At the Improve and Control stage, namely, the steps taken to minimize the problem or waste (preventive actions) and what steps or ways to do if the problem or waste occurs again (contingent actions).

Authors: Kurnia Gita , Hanan Fatika Adzkia  , Nur Layli Rachmawati
Published: May 2023

A dry port is established as an inland extension of a port. Tanjung Intan Port, which is located in Cilacap and within the range of tsunami risk zones, has no dry port to accommodate its distant customers. This research proposes a dry port location selection for Tanjung Intan Port with the following main criteria: safer from tsunami risks and achieve maximal demand coverage. By applying AHP (Analytical Hierarchy Process), the location candidates were ranked and further selected using MCLP (Maximum Coverage Location Problem) to choose the best candidate. The study result selects Maos railway station as the most attractive dry port location. The feasibility study result shows that the location has: (1) a lower risk of tsunami impact, (2) potential for the port’s market expansion, (3) less pollution potential, (4) adequate railway tracks, (5) large area, (6) good location away from densely populated areas and, (7) easy access for trucks.

Published: May 2023

This paper presents recommendations for a Multicampus course, developed through a Student as Partners project. In this project students, a teacher and an educational developer collaborated following the principles of the Students as Partners framework. Through interpretation of previous course evaluations and discussions, we created a shared understanding of how the course had worked and what to improve. Our main recommendations are to have lectures and learning activities that are diverse and adapted to the students’ different needs. These recommendations are not groundbreaking in themselves, however, the grounding in a common understanding through the use of the Student as Partners framework is novel and gives new perspectives to course development and educational development in general.

Published: May 2023

The study of hepatic hemodynamics is of importance in understanding both hepatic physiology and diseases as well assessing the effects of portosystemic shunting and liver transplantation. The liver has the most complicated circulation of any organ many physiological and pathological processes can affect it (1,2). This review surveys the methods available for assessing liver blood flow, examines the different parameters being measured and outlines problems of applicability and interpretation for each technique. The classification of these techniques is to some extent arbitrary and several so called 'different' methods may share certain common principles. The methods reviewed have classified into two groups (Table I):Those primarily reflecting flow thorough discrete vessels or to the whole organ and those used to assess local microcirculatory blood flow. All techniques have their advantages and disadvantages and in some situations a combination may provide the most information. in addition, because of the many factors affecting liver blood flow and sinusoidal perfusion, readings in a single subject may vary depending on positioning, recent food intake, anxiety, anesthesia and drug therapy. This must be borne in mind if different studies are to be meaningfully compared .

Objetivo. Determinar la distribución por sexo de los residentes de ortopedia y traumatología en Colombia en tres momentos fundamentales: la inscripción al proceso de selección, la admisión a la especialidad y la terminación del programa académico y obtención del correspondiente título.
Metodología. Estudio transversal en el que se analizaron los datos registrados entre 2001 y 2021 en el Sistema Nacional de Información de la Educación Superior - SNIES para los programas de posgrado de ortopedia y traumatología.
Resultados. En comparación con 2001, la proporción de mujeres egresadas de especialidades quirúrgicas en 2021 aumentó (26,56% vs. 44,84%). En el caso de los programas de postgrado en ortopedia y traumatología, entre 2007 y 2021, 16 979 individuos se postularon al proceso de admisión, 975 fueron admitidos y 702 se graduaron como ortopedistas, siendo la proporción de mujeres en cada etapa 22,47%, 22,56% y 16,80%, respectivamente. Además, en relación con el número de admitidos estratificado por sexo, el porcentaje de mujeres que se graduaron como ortopedistas fue notablemente menor que en los hombres (53,64% vs. 77,35%).
Conclusiones. A pesar del aumento en la proporción de mujeres egresadas de las especialidades médicas, en el caso de ortopedia y traumatología, las mujeres siguen teniendo una participación muy baja en términos de aspirantes inscritos, admitidos y egresados.

Introducción: la histiocitosis sinusal con linfadenopatía masiva (HSLM) es un trastorno histiocítico benigno que afecta con mayor frecuencia a adultos jóvenes. La afectación ósea es poco frecuente y se suele presentar en huesos largos.
Presentación del caso: hombre de 38 años con diagnóstico de HSLM según biopsia de nódulo cutáneo. Seis meses después del diagnóstico, presentó dolor mecánico en el pie derecho, por lo que asistió a una nueva consulta. Se realizó exploración física y radiografía simple, encontrando una lesión lítica en el hueso cuneiforme medial que posteriormente fue confirmada con tomografía computarizada y resonancia magnética nuclear. Por lo anterior, se realizó la resección de la lesión lítica, curetaje y relleno con cemento de fosfato de calcio HydraSet (Stryker®). Se realizaron pruebas inmunohistoquímicas y estudio anatomopatológico en el tejido resecado, evidenciando tinción de proteínas CD68 y S100 positivas, y tinción de proteina CD1a negativa, así como proliferación histiocitaria. Un año después de la cirugía, el paciente se encontraba asintomático y realizaba actividades sin ninguna restricción.
Conclusiones: esta enfermedad es poco frecuente; no obstante, debe considerarse en el diagnóstico diferencial de lesiones líticas en huesos, especialmente cuando hay lesiones en otras partes del cuerpo.

Introducción: el enclavijamiento endomedular (EE) es una opción terapéutica para fracturas de la diáfisis humeral; sin embargo, algunos pacientes tratados con EE desarrollan signos de pinzamiento subacromial y disminución de la fuerza en movimientos de flexión y abducción.
Objetivo: evaluar el impacto en el hombro del uso del EE anterógrado para el tratamiento de fracturas de la diáfisis humeral en términos de dolor, funcionalidad y signos de pinzamiento subacromial.
Metodología: estudio observacional retrospectivo realizado en 25 pacientes adultos con fracturas de la diáfisis humeral tratadas con EE anterógrado. Se realizó seguimiento entre 6 y 12 meses después del procedimiento, valorando la funcionalidad (arcos de movimiento y escala QuickDASH) y la presencia de dolor (escala visual análoga [EVA]) y signos de pinzamiento subacromial (según Yocum, Neer y Hawkins-Kennedy). Los datos se describen utilizando frecuencias absolutas y relativas para las variables cualitativas, y medias y desviaciones estándar para las cuantitativas.
Resultados: las medias de la flexión anterior, puntaje en la escala QuickDASH y escala EVA fueron 145° (±31,6), 6,1 (±8,5) y 2,32 (±2,06), respectivamente. El 32% de los pacientes presentó uno o más signos de pinzamiento subacromial. Además, la consolidación completa de la fractura ocurrió en todos los casos.
Conclusiones: dado que no se evidenció un impacto significativo en el hombro en términos de movilidad, dolor o signos de pinzamiento subacromial y que la consolidación de la fractura ocurrió en todos los casos, el EE fue adecuado para el tratamiento de fracturas de la diáfisis humeral.

Introducción: los síntomas, signos y hallazgos imagenológicos e histológicos del quiste óseo aneurismático (QOA) y el osteosarcoma telangiectásico (OT) son similares, por lo que constituyen uno de los diagnósticos diferenciales más difíciles de establecer.
Presentación del caso: mujer de 19 años que asistió al servicio de urgencias de un hospital de cuarto nivel de atención en Bogotá por dolor en la cadera izquierda, donde se identificó lesión lítica en el cuello del fémur y se remitió a consulta externa. Tres días después, la paciente regresó al servicio de urgencias por dolor en la cadera izquierda e incapacidad funcional. Mediante radiografía y resonancia magnética, se identificó fractura transcervical de la cadera en el lugar de la lesión lítica, por lo que se sospechó la presencia de QOA u OT. La paciente fue llevada a cirugía y se realizó biopsia por congelación, confirmando el diagnóstico de QOA; por lo tanto, se realizó curetaje y fresado de la lesión, reducción y fijación de la fractura con sistema DHS (dynamic hip screw), y aplicación de injerto y cemento óseo. Cuatro días después del procedimiento, la paciente fue dada de alta. En el seguimiento a los ocho meses, se evidenció recuperación completa de la funcionalidad de la cadera y ausencia de dolor.
Conclusión: en pacientes en los que hay una alta sospecha de este tipo de lesiones óseas, es importante realizar un estudio histopatológico para confirmar el diagnóstico de QOA u OT, e instaurar un tratamiento adecuado y oportuno, que sin duda contribuirá a un mejor pronóstico, particularmente en términos de supervivencia.

Introducción. La ruptura del ligamento anterior cruzado (LCA) es una condición frecuente a nivel global y la reconstrucción artroscópica con autoinjerto de hueso-tendón-hueso (HTH) constituye una de las técnicas quirúrgicas para su tratamiento. No obstante, esta técnica puede generar complicaciones como dolor anterior de rodilla. Actualmente, se desconoce su prevalencia en Colombia.
Objetivo. Determinar la frecuencia de dolor anterior de rodilla luego de la reconstrucción de LCA con autoinjerto HTH en pacientes operados en un periodo de 4 años en el Hospital San José en Bogotá, Colombia.
Metodología. Estudio descriptivo realizado en pacientes con diagnóstico de ruptura del LCA llevados a cirugía de reconstrucción de este ligamento mediante HTH entre enero de 2014 y diciembre de 2017. Se realizó una encuesta telefónica y, en los pacientes con dolor, una valoración clínica para caracterizar dicho dolor. Los datos se describen usando frecuencias absolutas y relativas, así como medianas y rangos.
Resultados. Se incluyeron 257 pacientes, la mayoría de los cuales eran hombres (87,5%) y adultos jóvenes (42,4%). La prevalencia del dolor anterior de rodilla fue 11,6%. Además, ninguno de los pacientes operados en 2014 presentó dolor anterior de rodilla en el momento de la valoración (a 4 o más años de seguimiento).
Conclusiones. La reconstrucción del LCA mediante HTH es una técnica quirúrgica que ofrece excelentes resultados en términos de escalas funcionales y estabilidad de la rodilla. La prevalencia de dolor anterior de rodilla fue inferior a la reportada en otros estudios y se localizó con mayor frecuencia en el sitio donante (polo inferior de la rótula y tuberosidad tibial anterior).

In general, home automation means controlling the utilities and features of the household appliances. To achieve this most automation systems use Wi-Fi as a communication technology. But when it comes to Wi-Fi the overall setup cost will be higher and it also not possible to connect all the household appliances to the network. For that we had proposed a system called smart home automation system based on Li-Fi technology. Since its Li-Fi, a VLC, we can use our domestic household LED lights as a transmitting source. This system will control the power up function of the appliances. And the overall setup of this system is very simple on both the hardware and software sides. The specific light encoded data will be transmitted by the LEDs and decoded by photodiode at the receiver section. By implementing this Li-Fi technology in home automation will bring the new era of automation with simple, speed, cost-effective and secure features. And this will be the dual benefits of both luminance and automation in a single implementation setup. And on the security side also it will provide secure communication with the ability to be impenetrable through physical objects because of the nature of light. Not only smart devices, every electrical device can be operated with this technology implementation. Key Word: Home Automation; LI-FI; Sensor; Connection; Future

Melamine formaldehyde-based composites have been preferred in many sectors. Various reinforcing materials are used to improve the physical and chemical properties of these composites. To lighten melamine formaldehyde-based composites, low-density organic and inorganic industrial wastes are reinforced. Inorganic factory wastes are used to increase the hardness of the composites. Besides, mineral fillers are preferred to improve the thermophysical properties of composites. In industrial applications, many modification processes have been carried out to develop both the physical and chemical properties of such composites. For composites, importance is given to optimum mechanical strength, nonflammability, surface morphology, pore structure, and distribution. Depending on the intended use of composites, the desired properties may differ in each sector. For example, there are prominent standards in every sector such as home appliances, furniture, automotive, construction, electronics, and decoration. In these standards, it is desirable to have optimum properties such as mechanical strength, hardness, density, thermal conductivity, non-flammability, and thermal stability. Therefore, these standards can be achieved by applying appropriate reinforcements and modification processes to improve the properties of melamine formaldehyde-based composites.

Substitution box (s-box) is one of the important structures that perform the mixing process for encryption algorithms. Therefore, strong s-box structures are needed to develop effective encryption algorithms. The most important feature of the S-box is that it has a nonlinear structure. In this way, it can effectively scramble the data to be encrypted. More than a hundred new algorithms have been proposed using many approaches to obtain s-box structures with high nonlinearity. In this study, the performances of the s-box generation approaches in recent years were compared according to their non-linearity values. In addition, the advantages and disadvantages of these approaches have been discussed and suggestions have been made especially for researchers who will just start in this field.
