Authors: Derin Paşaoğlu Derya ,   Karadeniz Technical University, Mirgaleev Il’nur M. ,   Marjani Institute of History of the Tatarstan Academy of Sciences
Published: July 2024

Research Objective: To analyze the laws by which the Nogai society existed. Research Materials: An archival document numbered BOA.A.MKT.UM.414-24 in the Ottoman Archives of the Prime Minister’s Office, in the State Archives of the Republic of Turkey. Results and Scientific Novelty of the Study: The laws of the Nogais, recorded by Ottoman officials, are introduced into scientific circulation. The lifestyle of the Nogais corresponded to the steppe culture; they moved between pastures and winter quarters and were engaged in cattle breeding. The Nogais, living in tribes, were under the authority of their bek. The steppe culture of the Nogai lifestyle complicates the study of their laws. The problems faced by the Nogais upon resettlement to Ottoman lands in the 19th century became a topic for official correspondence between provincial structures of the Ottoman state and the center, and some of the mentioned Nogai laws were recorded as the main reason for the problems that arose. The archival document, registered under number BOA.A.MKT.UM.414-24 in the Ottoman Archives of the Prime Minister’s Office, in the State Archives of the Republic of Turkey, is a document written by the mutasarrif of Adana to the center, who had problems with the Nogai settlers they wanted to resettle in Adana.

Authors: Subramanya Vinita , Spychalski Julia , Coats Sarah , Gottstein Elisheva , Chancellor John , Kulshreshtha Ambar
Published: July 2024

Background and Objectives: In health care, empathy is a clinician’s ability to understand a patient’s emotional state and convey that understanding in their care; and being culturally sensitive is communicating and respecting cultural differences. Providing health care on digital platforms introduces a new challenge of conveying empathy and cultural sensitivity. This study aimed to evaluate whether patients who were seen in-person had different perceptions of clinicians’ empathy and cultural sensitivity compared to those who were seen via telemedicine.
Methods: In this cross-sectional pilot study, we recruited primary care clinicians (N=8) and their telemedicine (N=14) and in-person patients (N=20) from two clinics at Emory University in Atlanta, Georgia. We evaluated clinicians’ empathy and cultural sensitivity by self-report and from patients’ standpoints.
Results: Patient perception of clinician empathy scores were similar (P value=.31) for in-person appointments (mean=33.8) and telemedicine appointments (mean=31.3). Patient perception of culturally sensitive communication varied in the sensitivity domain and was consistently low for the domain of discrimination (suggesting low discrimination among the clinicians) regardless of the modality of the visit.
Conclusions: This novel pilot study demonstrated comparable empathy and culturally sensitive communication scores in telemedicine and in-person visits, highlighting the potential for continued use of telemedicine in outpatient primary care. Delivery of care via telemedicine can enable an expansion of high-quality care to underserved communities. Future studies are needed to confirm our findings to enhance the experience of telemedicine visits for patients and clinicians.

A DATA-DRIVEN ANALYSIS OF THE IMPACT OF THE DIGITAL RENMINBI ON MULTILATERAL CURRENCY SWAP AGREEMENTS WITH COUNTRIES IN THE ISLAMIC WORLD
Authors: Yu Shanxuan
Published: July 2024

China was once among the world's poorest countries, but during the past forty years, it has turned into an economic powerhouse. Bilateral exchange lines are one of PBC's patented methods of promoting RMB internationalization. Swap lines were initially created to assist with RMB settlement in international trade due to the limited RMB liquidity overseas. Prior to eventually expanding to other rising economies, the first geographic reach concentrated on Asian neighbors. Swap lines can boost a loan's usage and reduce the apparent risk distribution of a loan in a rising currency. Swap lines have an impact that extends beyond their core usage in order to create a larger safety net. The PBC has established bilateral swap lines in addition to offshore clearing institutions in 25 markets to facilitate RMB payments. The e-CNY was created by the PBC for four main reasons. The general public's accessibility to digital money is the initial objective of the e-CNY. Additionally, it aspires to promote efficient, secure, and equitable retail payment systems. Third, the e-CNY will improve the efficiency of international payments. The fourth is that financial inclusion should be benefited. The empirical analysis underlined the crucial hopes that the e-CNY may promote bilateral currency exchanges between Islamic nations and China and may serve as a big economic boost for those nations.

This book was first published in 1977 as a chapter in the book Islam and Modernism by Wan Muhammad Ali, published by the Bureau of Education and Research, Malaysian Islamic Youth. Since the first issue this book has never been reprinted or published again. After 40 years passed, and after the author Sheikh Muhammad Uthman El-Muhammady died on 2013, the author felt called to revisit this writing, editing it and at the same time working on the publication of the edition so it can be read and studied by the young people now that seems to be in dire need of spiritual guidance and Islamic moral discourse in the lives of those who chaotic and seems to lose this common sense. As the author said, the cultivation of Islamiyyah morals can solve moral problems faced by humans in all ages, because of the truth in it is based on human nature does not change, whether those facts are about his own occurrence or about his main attributes, or about the properties that are opposite to it. In the face ambiguities about human nature in philosophical teachings relatively modern, Islam came to bring its teachings about human beings with attributes and with concepts that can save us. Understanding of Islamic morals as which is expressed in this book as well as its implementation in individual and community life will lead to the success of human life which is truly in saniyyah, which can save them from false teachings about human.
Evaluation of Municipal Solid Waste Management in Brazilian Cities According to the Updated Waste Management Condition Index –ICGRA
Authors: GP Mendez
Published: July 2024

The present study evaluates municipal solid waste management through environmental indicators. To this end, the updated Waste Management Condition Index (ICGRA), formulated through changes to the ICGR, a proposed index validated by Dantas KMC, et al. was designed and used as a tool. To create the ICGRA, 22 environmental performance indicators were inserted with the purpose of adjusting the index to the requirements of Brazil’s National Solid Waste Policy (PNRS) and to the current conditions of the solid waste treatment. The scores were obtained by assigning weights to the indicators and with the value found for each municipality, the waste management was classified as adequate or inadequate, in a range between zero and ten points. The ICGRA method was applied in ten municipalities of small and medium size in the state of Rio de Janeiro. None of them reached the level of management considered adequate by the method. In addition to the 22 indicators inserted, the ICGRA worksheet contains the 40 original ICGR indicators used in the evaluation carried out in 2008. Thus, it was possible to evaluate the results in a comparative way, showing that only four of the ten municipalities studied improved. The improvement seen in the 4 municipalities is in relation to the index used in the evaluation, the ICGR, same index used in 2008. It does not mean that all aspects of solid waste management have evolved, but that the index composed of waste management evaluation indicators improved in relation to 2008. The results also reveal that the PNRS was not effective in its first seven years. The proposed method proved to be practical and easy to apply, helping to improve the evaluation methods in the area of waste management already developed in Brazil.

Taken decisions, strategies and polices of the companies owned these fields are also presented. Recommendations to develop those fields are obviously presented.
The development and integration of microfluidic devices and electrochemical sensors for potential use in clinical and environmental applications
Authors:   , Naserikarimvand Shirin
Published: July 2024

The objectives of this research has been the development of various microﬂuidic devices for diﬀerent applications, these applications include cell capture and integrating with sensing platforms. Novel microﬂuidic devices have been developed, these have been functionalised to contain antibodies that are able to capture cells that are pumped through the device. The device has been demonstrated as working successfully by microscopic analysis of the captured cancer cells in the device. This work demonstrates the successful proof of concept that these novel devices are functional and are ready to be taken forward for further development. A microﬂuidic adapter containing activated charcoal ﬁlter paper has been created that integrates with a DMSO-melanin pH sensor in order to overcome stability problems that occur when the sensor is used with blood samples. It is theorised that anions in the blood interfere with the silver reference electrode on the sensor. Anions bind to activated charcoal and as such can be removed by this ﬁlter paper. An increase in signal stability was observed however further investigation is required to see whether this impacts on the pH sensitivity of the sensor. Photonic measurements on novel waveguide chips have been demonstrated an initial proof of concept for the creation of a sensing platform that is based on this technology. The waveguide chips have been shown to be sensitive to changes in the refractive index measured when the device was tested with diﬀerent samples including water, air and gold nanoparticles. The waveguide chips are also sensitive to changes in temperature. Future work involving functionalising these chips in order to make them respond to speciﬁc changes and analytes shows promise for the development of a novel sensor platform that has potentially useful environmental and clinical applications. Research into using square wave voltammetry and screen printed electrodes to investigate bacterial characteristics has been expanded and the suitability of using this technique for identifying bacteria has been investigated by testing multiple diﬀerent bacterial species with these electrodes. This work has also introduced screen printed electrodes with gold working electrodes as well as the carbon working electrodes that have been used in previous work carried out in this research group. The voltammograms produced using the gold working electrode were better than those that were produced using the carbon working electrode as the shape of the voltammograms did show some correlation with the bacterial species that they were tested with. This could be investigated further by expanding on the number of diﬀerent species tested and increasing the number of replicates.

Published: July 2024

The purpose of this research is to investigate public service motivation and examine the influences of organizational factors within Bahamian public and non-profit organizations of health and social welfare services from the perspective of Herzberg’s dual-factor theory along with self-determination theory and person-organization fits. A multiple case study is used with a mixed method design. Data were obtained using q-technique and semi-structured interviews. Public service motivation is tested with q-technique approach using revised public service motivation and continuous commitment scales. The sample consists of 12 first line managers and 25 employees. Data collection was conducted from January to March 2020. The results show that two dimensions of public service motivation are significant and contextual. Within public organizations commitment to public values is significant, and non-profits regard compassion dimension as important. The results further reveal differences in public servants and non-profit workers’ attitudes and perceptions about organizational factors. The evidence shows within public organizations, public service motivation is enhanced by teamwork, workload support, and harmonious working environment. However, the evidence also shows that inhibiting access to advanced education, rules and regulations, lack of autonomy, and inadequate working conditions negatively influence public services within government organizations. The results within non-profit organizations reveal that autonomy, easy access to user-specific training, manager-employee association, and working conditions promote public service motivation and are significant. Employee to employee interactions and insufficient supplies, however, are shown to negatively impact public services. Overall public organizations have greater challenges, but public services are delivered with team approach and public servants supporting one another. Non-profit organizations have fewer difficulties and deliver public services to meet service users’ needs.

Published: July 2024

This research analyzes the sister city cooperation between Magelang City-Tula City using three layers of paradiplomacy. The layers determine the focus of cooperation and its potential for future smart city implementation in Magelang City. Paradiplomacy has become a promising instrument in the context of sister-city cooperation proposed by regional governments, mostly in forging relations with global cities. Although paradiplomacy is considered the practice of ‘high politics’, various sectors can be operated within the activity, including trades, education, culture, tourism, and technology. As qualitative research, the data was gathered through field and literature studies. Findings highlight that the cooperation has not been further performed by related regional offices beyond the agreement stage (Letter of Intent). Therefore, little can be measured about the impacts it has brought to Magelang City's development, particularly in the pursuit of smart city adoption. Regardless, improvement and programs related to the second layer of paradiplomacy through sister-city cooperation might benefit the Magelang City government in smart city implementation.

Published: July 2024

Renewable energy and power utilities inspection by autonomous aircraft enables rapid and effective risk-free assessment of the state of systems, and provides a qualitative and accurate assessment of defects and damages. To realize maximum operational benefits of aerial inspections, effective controls for autonomous aircraft must be ensured and the system should be operated in an optimal policy. Hence, the objective of this paper is to consider optimal control strategies for a quadrotor helicopter type UAV. Based on some structural properties of the considered system, in particular the flatness property, we suggest a control strategy that ensures tracking a time parameterized path that connects two given points in the state space while minimizing the energy consumption. The proposed controller enables longer-endurance missions for the quadrotor and effective supervision and inspection of large energy systems and power plants. In this paper the analysis of the control law takes into consideration the highly nonlinear dynamic model of the quadrotor and the electrical actuator model. The current approach in solving the optimal control problem under consideration allows one to eliminate the differential equation and to reformulate the optimal control problem to a nonlinear dynamic programming problem. The current approach can make monitoring operations of renewable energy plants by aerial vehicles, more efficient. Key words Aerial inspections for power utilities, quadrotors, nonlinear systems, optimal control, minimum energy.
Is Objection to Wind Energy Justified?
Authors: Alrefai M. ,   Mechanical Engineering. Kettering University Flint, Michigan. USA, Pourmovahed A.
Published: July 2024

Wind power has been used by humans for over 7000 years. The first known example of wind power use is most likely the utilization of sailboats used by Phoenicians and Egyptians. Windmills have been used on a small scale for many centuries primarily for the purpose of milling grains and pumping water. The use of wind turbines to produce large amounts of electricity has occurred in recent times. The most powerful wind turbine today is an 8-MW turbine for offshore use. According to the U.S Energy Information Administration (EIA), as of March 2017, wind and solar power were contributing about 10% of the electricity generated in the United States. Resistance to change is a part of human nature and, as expected, has prompted some individuals and groups to oppose the development of wind power in their communities. The “Not In My Back Yard” (NIMBY) phenomenon is well known and has been cited as the force against many new developments in numerous communities around the world. This paper reports the results of a study investigating common reasons cited for objections to wind power installations. Under some circumstances, some of the claims against wind power may be justifiable while in other cases the objections appear to be completely baseless. Key words Wind Power, Renewable Energy, Objection to Wind Power, Wind Power Disadvantages

One effort to increase the number of young workers absorbed in the agricultural sector is through agricultural vocational school education which is expected to grow the interest of agricultural vocational school students to work in the agricultural sector in order to overcome the decline in farmer regeneration in Indonesia. The research objectives are to: (1) Identify the interest of agricultural vocational school students in agriculture to work in the agricultural sector, and (2) analyze the factors that influence agricultural vocational school students' interest in working in the agricultural sector. The research was carried out in September 2023 at one of the vocational schools specializing in agricultural skills in Ciamis Regency. The research sample consisted of 78 students who were determined using cluster random sampling. Agricultural vocational school students' interest in working in the agricultural sector was analyzed descriptively, while the factors that influenced agricultural vocational school students' interest in working in the agricultural sector were analyzed using multiple linear regression analysis. The research results show: (1) The majority of agricultural vocational school students who are interested in working in the agricultural sector are in the medium category, and (2) The social environment, community environment and social status have a significant influence on agricultural vocational school students' interest in working in the agricultural sector, while their parents' income has no significant influence.

Se examina la economía mundial en él periodo reciente en que ha ocurrido el resurgimiento de una nueva etapa de proteccionismo y, por ello, cambios y ajustes en las relaciónes entre las naciones. El centro del problema es la imposición unilateral de aranceles por parte de Estados Unidos a China y otros países, entre ellos México, así como la reacción de las naciones afectadas, implicando nuevas relaciones comerciales. Las tradicionales alianzas norteamericanas con otros países y en especial con otras potencias se vieron alteradas, así como las relaciones multilaterales y las políticas de cooperación, ya de por si deficientes. El déficit comercial estadounidense es un problema de déficit de ahorro interno. Por tanto, el déficit comercial no se resuelve mediante políticas comerciales proteccionistas, sino mediante políticas macroeconómicas. Otro ajuste internacional importante es la separación de Gran Bretaña de la Unión Europea, Brexit. Se hace una revisión de las delicadas relaciones de Estados Unidos con China y Rusia, así como entre la Unión Europea y Rusia.

Universal Health Coverage is a health insurance system that ensures every citizen in the population has equitable access to quality and effective promotive, preventive, curative, and rehabilitative health services. Meanwhile, the Medan City Government of Indonesia is trying to improve health services through the Medan Berkah Health Insurance Program by adopting Universal Health Coverage, which aims to provide Universal Health Coverage to the entire community. This study aims to explain the implementation and projection of the development of health services of the Medan City Government with the Universal Health Coverage System in the Medan Berkah Health Insurance Program which is intended as a step in providing opportunities for all people to get equal opportunities in health services, especially for the poor. This research uses qualitative research by using the literacy study method by studying related documents and conducting in-depth observations. Data analysis included data reduction, presentation, and conclusion drawing. The Medan City Government implemented the Universal Health Coverage Program in Jaminan Kesehatan Medan Berkah, which aims to improve health services in the city. The government is committed to simplifying the bureaucracy, managing the medical workforce, and collaborating with stakeholders and the community. However, challenges include low community participation, limited resources, lack of coordination, and limited access to information, which hinder the successful implementation of the program.
Análisis comparativo de redes neuronales profundas para la predicción del precio de mercado de bitcoin
Authors: López-García Aarón
Published: July 2024

Uno de los problemas más desafiantes de los últimos años es el estudio financiero de las criptomonedas con el fin de conocer su comportamiento futuro. El auge de la inteligencia artificial nos está ofreciendo herramientas que nos permiten abordar el asunto con mayor precisión. En particular, el aprendizaje profundo nos permite generar redes neuronales que aprenden de grandes volúmenes de datos, identificando así patrones imperceptibles para los humanos. En este trabajo, nos centramos en el estudio de Bitcoin, la criptomoneda de mayor valor y popularidad del mercado actualmente. A la hora de pronosticar su precio, se han implementado tres tipos de redes neuronales profundas y un modelo comparativo. Los resultados del análisis comparativo concluyen que los patrones temporales resultan ser mías representativos que los espaciales al estimar el comportamiento del precio de cierre futuro de Bitcoin.
Modalidades de reaseguro basadas en el número de siniestros
Authors: Pons Cardell M. Àngels , Sarrasí Vizcarra Francisco Javier
Published: July 2024

En este artículo se presentan diferentes modalidades de reaseguro basadas en el número de siniestros. Para su estudio se propone dividirlas en dos categorías, reaseguro de los k siniestros más grandes y reaseguro del exceso de los k siniestros más pequeños, en función de si es el reasegurador o la cedente quien establece el número de siniestros a su cargo. Dentro de cada categoría se proponen tres modalidades, cuota parte, exceso de pérdida y exceso de siniestralidad, las cuales dependerán de la forma en que se haga la transferencia de riesgo entre la cedente y el reasegurador. Para calcular la prima de la cedente y del reasegurador se deben de determinar las funciones de distribución del coste de los k siniestros más grandes y de los k siniestros más pequeños. El problema radica en que sus expresiones analíticas son poco operativas, resolviendo este problema ordenando directamente los siniestros aplicando el método de simulación de Montecarlo.
Experimental validation of asymmetric PZT optimal shape in the active vibration reduction of triangular plates
Authors: Kuras Romuald , Hajder Sebastian
Published: July 2024

In the active vibration reduction of two-dimensional structures, piezoelectric actuators of regular shapes, e.g. rectangular, circular, are commonly used. However, the shape of the transducers can be irregular, asymmetric (a-PZT), and its geometry can be an object for optimization. The paper presents an experimental validation of the application of optimal shaped a- PZT in the active reduction of triangular plate vibrations. Optimization was based on the criterion of the maximum bending moment. This means that the center of a-PZT is located at the point where the bending moment of the plate has reached its absolute maximum. The isosceles right triangular plate with simply supported edges was chosen as the research object. The research confirms the validity of the criterion used for optimization and may be an introduction to considering the use of optimal a-PZT in the active reduction of vibrations for more complex structures.
Sound power level as a measure of efficiency of Distributed Mode Loudspeakers
Authors: Czesak Karol , Kleczkowski Piotr
Published: July 2024

Distributed Mode Loudspeakers (DMLs) are characterized by properties, which make them significantly different from conventional electrodynamic loudspeakers. Such differences occur due to the design assumptions of the DML. In this work, a series of SPL measurements of DML in a reverberation chamber has been carried out, which were compared with those for an electrodynamic loudspeaker. Sound power level was determined from the results of conducted measurements for both types of transducers. It was calculated in 1/3 octave bands, for the pink noise excitation. The sound power level obtained with these two different types of loudspeakers is not significantly differing between each other.
Profile Analysis: A framework for the study of auditory sound spectrum analysis
Authors: Żera Jan
Published: July 2024

Profile Analysis (PA) is a research approach developed by David M. Green and his associates, aimed at measuring listeners’ ability to discern changes in the spectral envelope shape of complex tones. PA introduces an innovative method by separating across-frequency spectral envelope shape comparisons within a complex tone and across-time level comparisons within specific frequency channels. This paper revisits the outcomes of several PA studies and examines the correlations between PA and the results obtained from experiments involving harmonic signals and listening tests designed to enhance timbre evaluation skills among sound engineering students at the Chopin University of Music in Warsaw.
