Este escrito registra la construcción de un artefacto móvil que se transporta mediante mecanismos internos, carentes de electricidad para su funcionalidad. Su apariencia formal se basó en las características estructurales de un ave exótica colombiana y el requerimiento de diseño planteado por el docente fue que la mínima longitud recorrida por el elemento móvil fuera de 2 metros, además de la adición de un movimiento que, igual que el mecanismo de desplazamiento, no tuviera componentes eléctricos. Esta ha sido una experiencia de fabricación, estudio formal, y aprendizaje de mecanismos efectiva, práctica y con enseñanza progresiva.
La belleza en la Grecia antigua y en el diseño contemporáneo
Authors: Tamayo Castellanos Carlos Julián
Published: February 2023

Es frecuente observar cómo elementos del diseño actual son retomados de tendencias clásicas; de hecho, son fuente de inspiración constante para nuevos diseñadores que buscan significado en ellas. Sin embargo, relucen diferencias sustanciales que deberían tenerse en cuenta a la hora de tomar, por ejemplo, a la Antigua Grecia como eje de creación. Analizando el ideal de belleza, la producción artística y la funcionalidad contenida en el diseño griego, se puede encontrar que la exaltación helénica de lo bello por medio de las formas simétricas, naturales y masculinas difiere de la intención contemporánea de valorar la subjetividad y la influencia del contexto. Asimismo, la jerarquía que suponían las bellas artes en la antigua Grecia es rebatida por la tendencia actual de generar experiencias desde materiales autóctonos. Por último, se expone el giro que toma la idea griega del diseño como una herramienta básicamente decorativa, pasando a ser hoy un commodity.

Claims that women are weak, not authoritative, and tend to use their feelings, make women discriminated against in the public sphere. Even in Islamic history, women are considered worthless so when a baby girl is born, it is considered a disgrace, and many are buried alive. Thus, in accordance with the times and knowledge, this paper will review the roles and gait of women, especially in their capacity as leaders. This paper will examine the text of the prophet's hadith about women's leadership and try to contextualize it with Indonesian reality. The conclusion of this article is that women are given things and obligations to become leaders as long as they have the capacity, capability, and quality to carry out their duties and responsibilities. So, in the context of 'worldly' leadership, it is not seen from gender, but from the qualifications, capabilities, and qualities possessed by a person.

Authors: Ismail Nurhidayati
Published: February 2023

Sanad is important in Islam. The existence of sanad in a hadith determines whether a hadith can be accepted (Maqbul) or ditolah (mardud). In addition, many of the famous (popular) hadiths circulating in the community are not necessarily the hadith considered shahih or even false. This study aims to examine several hadiths that are popular in the community. The method used in this study is the takhrij method, by examining the historical sanad-sanad in question. In this study, the history studied was three pieces. From the results of oenelitian, the three histories that were originally considered hadith, it turns out that none of the hadiths have a history from the Prophet Muhammad SAW, some are maudhu' (false), and are also popular Arabic syi'ir.

Authors: Jamal Johari
Published: February 2023

Artikel ini mencoba untuk membahas perilaku berbagi pengetahuan dalam Islam dan kelengkapan teknologi yang memfasilitasi dan meningkatkan sarana berbagi pengetahuan di dunia saat ini. Berbagi pengetahuan memainkan peran yang sangat penting bagi organisasi dan masyarakat dalam mendorong orang untuk berbagi pengetahuan, ide, keterampilan, pengalaman dan pemahaman satu sama lain di dalam dan di luar organisasi atau ke dunia luar. Berbagi atau menyebarkan ilmu adalah bagian dari dakwah dalam Islam dan dianggap sebagai amal bahwa orang berniat menyumbangkan ilmunya dengan cara mentransfer atau menukarnya. Selanjutnya, teknologi bertindak sebagai alat untuk berbagi pengetahuan yang memungkinkan pengetahuan untuk didistribusikan di seluruh atau di dalam organisasi dan komunitas. Namun, Teknologi tidak ada artinya jika kemauan untuk berbagi pengetahuan satu sama lain tidak dilakukan. Namun, ada beberapa tantangan dalam upaya manajemen pengetahuan terutama tentang berbagi pengetahuan. Kebanyakan orang enggan membagikan ilmunya karena beberapa alasan seperti kehilangan kekuasaan, rasa tidak aman tentang nilai ilmunya, masalah kepercayaan, takut akan konsekuensi negatif dan masalah keuntungan. Sebagian besar masalah ini terkait dengan masalah pribadi atau manusia. Banyak yang telah dikatakan berdasarkan praktik konvensional tentang masalah ini tetapi sedikit yang dieksplorasi dari perspektif Islam. Artikel ini bertujuan untuk mengeksplorasi berdasarkan perspektif Islam mengenai pengetahuan, berbagi pengetahuan dan faktor motivasi untuk mendorong berbagi pengetahuan berdasarkan sudut pandang Islam sehingga cara lain untuk mendorong praktik berbagi pengetahuan dapat terungkap. Penelitian ini menggunakan pendekatan kualitatif berdasarkan kajian literatur yang bersumber dari Al-Qur‟an, Al-Hadits, dan literatur sebelumnya yang relevan. Kajian ini diharapkan dapat memberikan kontribusi bagi pengembangan teoriteori yang berkaitan dengan berbagi pengetahuan dalam perspektif Islam. Hasil penelitian menunjukkan bahwa pengetahuan dapat dipelajari dan diperoleh manusia dari berbagai sumber dan tuturan dalam Al-Qur‟an dan Al-Hadits.

Authors: Rohmi Misfi Laili
Published: February 2023

Poverty is still a central issue in developing countries like Indonesia. The government has made various efforts to reduce poverty, one of which is through the Family Hope Program (PKH). In contrast to other types of poverty reduction policies in general, PKH focuses on improving the quality of Human Resources (HR) through increasing access to health and education. The hope is that with quality human resources, the poverty rate can decrease in the future. In its implementation, PKH cannot be separated from various problems that are suspected to be incompatible with values in Islamic economics. Therefore, this study aims to determine the implementation of PKH from the perspective of Islamic economics. This type of research is field research by taking the location in Pringsewu Regency, Lampung. The method of data collection was carried out by interviewing purposively selected informants sampling. The collected data then analyzed by using a qualitative descriptive approach. Finally, this study concludes that the implementation of PKH in Pringsewu Regency successfully fulfilled 3 (three) criteria, namely: right on target, right in number, and appropriate in use. The criteria for being on time have not been achieved because of delays in distributing PKH assistance. Meanwhile, in the perspective of Islamic economics, PKH is considered to have met the criteria of justice, responsibility, and takaful (social security)

Published: February 2023

In papers [2,4,5] the solution relations and the algorithm of the method of block iterations of solving linear and nonlinear equations by the semivanalytic finite element method for curvilinear inhomogeneous prismatic bodies are realized. In paper [1], a numerical study of the convergence of solutions was performed, and a wide range of test problems for bodies with smoothly and abruptly changing physical and geometric characteristics in elastic and resilient-plastic formulation was considered. In paper [6], to confirm the reliability of the results obtained on the basis of the semi-analytical finite element method, the effectiveness of this approach for the calculation of curvilinear inhomogeneous prismatic objects is shown. Solving control problems of the theory of elasticity, thermoelasticity and thermoplasticity, as well as problems of shape change makes it possible to draw conclusions about the reliability of the results of the study of a selected class of objects based on the developed methodology and implements its application package.

In this work, using the methodology outlined in the above works, the solution of the spatial problem of plastic deformation of a prismatic body was solved on the basis of the semi-analytical method of finite elements, and the process of broaching a strip in the process of metal embossing was analyzed. The purpose of this study is to determine the spatial picture of the stress-strain state of the strip during drawing and to compare the spatial resolution with the flat one. A comparison of the parameters of the stress-strain state of the workpiece during the broaching process, obtained in flat and spatial settings, allows us to conclude that the research must be carried out on the basis of spatial calculation.
Investigation of the dynamic behavior of three-layer cylindrical shells of elliptical form under internal axisymmetric pulse loading
Authors: Gaidaichuk Viktor , Kotenko Kostiantyn
Published: February 2023

The results of the assessment of the dynamic behavior of three-layer cylindrical shells of circular and elliptical cross-sections under internal impulse loading are given. The finite-element method was used to calculate the indicators of the stress-strain state (SSS) of such structures by the NASTRAN software complex. The values normal deflections and normal stresses of circular and three elliptical forms of intersection of cylindrical structures are determined. A comparative analysis of the values of these indicators with the results of the dynamic behavior of uneven cylindrical shells was performed.

The shape and curvature of the cross section of three-layer cylindrical thin-walled composite shells significantly affect their SSS under dynamic impulse loading.

Replacing the circular shape of the cross section of a cylindrical structure with an elliptical one and increasing the ratio of the semiaxes of the elliptical section leads to an increase in normal deflections and normal stresses of the middle surface of the structure.
Study of the reliability and efficiency of using reinforced soil models within the framework of the finite element method
Authors: Solodei Ivan , Zatyliuk Gherman
Published: February 2023

Within the framework of the finite element method, the influence of the dimensions of the calculation model on the values of subsidence when using different soil models was studied.

Numerical calculations of the soil environment based on FEM differ from analytical ones in that a necessary condition for their application is the choice of a soil model, which is characterized by a different theoretical basis, which, with the help of equations of different complexity and input parameters of a different number, describe the behaviour of the simulated soil massif.

Given that the numerical solution of problems based on FEM involves the modeling of objects as a finite limited area, the question of choosing the lower limit of the calculation model in the study of subsidence is acute.

The stiffness of soils in their natural state increases with the depth of their occurrence. In simple soil models, such as the Mohr-Coulomb model, soil stiffness is a constant value. This circumstance leads to the fact that during numerical calculations, the deformations of subsidence increase linearly when the dimensions of the calculation model increase vertically.

Advanced models, such as Hardening Soil, can take into account the soil strengthening when the stress level increases, however they require a wide range of soil characteristics, which are determined by experimental methods, using special equipment, and the determination of a number of parameters is not regulated by regulatory documents.

It is shown that the use of the reinforced soil model proposed by the authors, which, on the one hand, complies with state building regulations, and on the other hand, does not require the involvement of additional physical and mechanical characteristics of soils, allows obtaining more accurate values of the parameters of the stress-strain state of the foundation.
Optimization of manipulator's motion mode on elastic base according to the criteria of the minimum central square value of drive torque
Authors: Loveykin Viacheslav , Mishchuk Dmytro , Mishchuk Yevhen
Published: February 2023

The results of studies of optimizing the mode of movement of the manipulator boom, mounted on an elastic base with a known stiffness the paper presents. The purpose of this scientific research is to reduce the oscillations of the manipulator turnout system, which will increase the overall efficiency of the manipulator, durability and reliability of the metal structure elements. The implementation of this goal have achieved by applying a controlled mode of operation of the drive with dynamic balancing of the drive mechanism. Using the Lagrange equation of the second kind, the equation of motion of the manipulator boom was compile and the expression for the generalized driving moment of the drive mechanism of the manipulator boom system was determined. This study considers only the angular displacement of the manipulator boom.  The unbalanced drive driving moment of the manipulator boom had estimated by the component of the total inertial moment of the moving mass of the boom and load and the static load from the mass of the boom and load on the drive mechanism. The elastic base of the manipulator was present in the form of a linear spring with a given coefficient of elasticity. Since the main external factor of oscillation, perturbation in the metal structure of the manipulator is the driving moment of the drive, so we used the target optimization function, which estimates the root mean square value of the driving moment of the drive mechanism. The main criterion for optimizing the mode of motion was present in the form of an integral functional, and the search for its minimum value is carried out using the methods of calculus of variations.

The results of this work can used by the drive control system at the design stage of the manipulator and during its operation. The dynamics of oscillations of such structural elements of boom systems of cranes is also estimated. The implementation of the obtained optimal modes of movement can be carried out using a hydraulic drive.
Analysis of concentrations of biogenic compounds discharged into water bodies with municipal wastewater
Authors: Shamanskyi Sergii , Pavliukh Lesia , Horbachova Olena , Repeta Victor
Published: February 2023

There were analyzed the effect of increased concentration of biogenic elements, as well as increased temperature on the frequency and magnitude of cyanobacteria reproduction. The goal was to identify the main causes of poor water quality in surface water bodies of Ukraine compared to European countries, as well as the impact of municipal wastewater entering water bodies on the quality of water in them. It is shown that pollution with biogenic elements (compounds of nitrogen and phosphorus) is one of the main reasons for unsatisfactory water quality in water bodies. This, in turn, is the cause of a number of such problems as the change in biological diversity and productivity of water bodies due to the eutrophication of freshwater and marine ecosystems, and the spread of diseases associated with unsatisfactory drinking water quality. One of the main sources of biogenic elements entering surface water bodies is municipal wastewater. Long-term observations of the composition of wastewater from municipal sewage systems indicate that the concentration of biogenic elements in them can be different. It largely depends on the sources of the effluents. In the total amount of nitrogen and phosphorus compounds entering the wastewater, a significant place is occupied by the economic activity of the inhabitants of the residential areas. Experience shows that, regardless of the level of water supply, the total mass of biogens entering the sewage systems from one inhabitant over a certain period of time is constant. However, taking into account the fact that the water availability for residents is different, the concentration of biogens in wastewater will also be different due to different dilutions. The calculation shows that for the entire possible range of water consumption levels (from 100 to 285 l/day per inhabitant according to the standards), the concentration of biogenic elements in wastewater can be: total nitrogen – from 38.6 to 110 mg/l; ammonium nitrogen – from 36.1 to 102.8 mg/l; nitrites – from 2.35 to 6.74 mg/l; nitrates – from 43.27 to 123.67 mg/l; total phosphorus – from 6.31 to 18 mg/l; phosphates – from 15.49 to 44.17 mg/l; organic phosphorus – from 1.26 to 3.60 mg/l.

Today, the anthropogenic impact on the environment is increasing, especially in urbanized areas and territories where active hostilities are taking place. Among a number of urgent environmental problems, it is possible to single out atmospheric air pollution, which occurs as a result of the concentration of road transport and industry in safe areas. The article presents the results of research into the state of atmospheric air pollution in the city of Vinnytsia using phytoindication methods, namely the degree of fluctuating asymmetry of warty birch leaves, and established the dependence of the fluctuating asymmetry on the level of traffic load. The research was conducted at the end of July in 2021 and 2022, after the end of the growing season of warty birch (Betula pendula). In the city of Vinnytsia, six representative experimental sites with different levels of anthropogenic load were identified. Fluctuation asymmetry coefficients of warty birch leaves were calculated for each experimental site and indicators of the asymmetry coefficient were determined. The level of motor vehicle load on experimental sites was established and a correlation-regression model of the dependence of the coefficient of fluctuation asymmetry of the leaves of the warty birch on the level of motor vehicle load was calculated. Conducting biomonitoring of aerotechnogenic pollution of urban ecosystems is necessary for finding ways to optimize its quality.

Solving the problem of the lack of effective technologies for the recovery of solid municipal waste consists, first of all, of the construction of an effective technological scheme for the collection, transportation, recovery and disposal of municipal waste. Achieving the goals of reducing the volume of municipal waste disposal to 30% in 2030, which are set by the National Strategy for Waste Management in Ukraine until 2030, is possible by applying coordinated technological stages of collection, transportation, recovery and disposal of municipal waste in settlements and territorial communities.Research is aimed at organizing effective and unified management of solid waste flows, their proper storage, collection, transportation, processing, and disposal taking into account the resource potential of solid waste, the need and feasibility of implementing a certain technology for processing, recovery and disposal of waste, taking into account its characteristics and application limitations, and the need to minimize the environmental burden associated with waste.The purpose and task of this publication are to describe the complete technological cycle of waste management and establish a sequence of unified methodical approaches to the stages and technological processes of solid household waste management (collection, transportation, recovery and disposal).
A Dispositional Account of Self-Deception: A Critical Analysis of Sartre’s Theory of Bad Faith
Authors: Du Plessis Guy
Published: February 2023

This essay addresses the notion of self-deception as articulated by Sigmund Freud and Jean-Paul Sartre. More specifically, I will critically assess Sartre’s notion of ‘bad faith’ (_mauvaise foi_) as a critique of Freud’s depth-psychological account of self-deception. Sartre’s main objection to Freud’s account of self-deception rests on his argument that for self-deception to occur there needs to be a conscious awareness of the coexistence of mutually incompatible beliefs, and that Freud had obscured this fact by splitting the self and with a mixture of jargon. In conclusion, I suggest a speculative and tentative hypothesis for self-deception that suggests an alternative to Freud and Sartre’s account of self-deception, one that views the self or self-system as having a disposition for self-deception when understood as having the capacity for fluid working self-states that are ‘expandable’ and ‘contractable’ that differ in self-complexity.

BACKGROUND: The world is experiencing an increasing number of people with cancer. Cancer care is an important but expensive specialized care requiring continuing research and funding. Private and public participation are key areas of care. We explored key elements of patient care in two centers; Medisprof Cancer center, University of Calabar Teaching Hospital (UCTH).

METHODS: This was a descriptive cross-sectional study. A researcher-assisted questionnaire was used to collect data, which was inputted and analysed using EpiInfo 7. Descriptive statistics were presented in tables and graphs.

RESULT: There was no statistically significant difference when all the responses in the areas of cancer care were compared for variance. Overall, 98% and 88% of patients were satisfied with services received at Medisprof and UCTH respectively. However, lack of communication between hospital departments and patients was reported in 5% at Medisprof and 64% at UCTH with 88% of the patients wanting to be better informed about the hospital services and availability. In Medisprof, on the other hand, only 5% of respondents undergoing diagnostic tests and imaging wanted to be better informed about the services.

CONCLUSION: Patient satisfaction and communication about services are integral parts of oncology patientcare. Effective oncology patient care can be achieved in both private and public hospitals with effective communication of services, proper navigation to the point of service stations and physician-patient communication.
Levels of methodological competence in foreign language teaching
Authors: Martynova R. , Bodnar S.
Published: February 2023

The notions “methodological competence” and “methodological competency” are differentiated in the scientific literature but their use in the methodological works is not always appropriate according to their essence. There is no gradation of these terms to different levels depending on knowledge, skills and abilities in teaching if to speak about people having different scientific and methodological potential. Therefore, it brings to the necessary to determine the level of methodological competence/competency of pedagogues who teach foreign languages in preschool, secondary, higher educational institutions and scholars-didacts and methodists. Due to the limited number of pages of a scholar paper only the problem of “methodological competence” differentiation is highlighted in the presented work. Purpose is to determine the levels of methodological competence of foreign language teachers with different scientific and methodological potential. Methods. Literature review on the topic of the research, comparative analysis of different definitions of methodological competence, generalization of the scholars-didacts and methodists’ experience. Results. This study analyses the notion “methodological competence” and determines its definition. Three levels of methodological competence have been developed and substantiated. The precise distinction between three levels has been defined and described taking into account the content of seven links of the teaching process introduced by us in the work. The first level of methodical competence correlates with the first level of language and speech competences (Martynova, Bodnar, 2022), as well as with the ability of calendar and lesson planning; the second correlates with the second level of language and speech competences, as well as with the ability to plana foreign language teaching process during the academic year and semesters, with the subsequent composing professional educational programs and syllabus; the third correlates with the third level of language and speech competences, as well as with the ability to plan foreign language self-study process, both in language and communicative and speech aspects, to the possibility of students creating their own speech products in a foreign language. Conclusion. It has been concluded that three established levels of methodological competence will clarify the essence of this concept, detail its components and become objective characteristics of educators’ methodological knowledge and skills.

Background: A variety of gas heaters are used in residential, administrative, and commercial buildings in Iran. Home packages (HP) and central heating boiler rooms (CHBRs) are among the most common types of heating systems that can be damaged during earthquakes and, thus, harm the building and the residents. Methods: By doing a survey and an interview in 50 residential buildings in District 16 of Tehran, the risks of these facilities were assessed during earthquakes from the viewpoint of the residents. To do the risk assessment, the failure mode and effects analysis (FMEA) model in the fuzzy space were applied. To analyze the risk priority number (RPN), defuzzification and the center of gravity method were used. Based on the results, 11 indicators were identified and evaluated for each system. Results: The mean RPNs obtained for both systems were almost equal (the difference was about 2%). Thus, no definitive superiority can be presumed for HP or CHBR when earthquakes happen. The major difference in the risk of each system can be separately evaluated based on the conditions of each building, confidence about the quality of installation, connections, pipe materials, electric wire corrosion, etc. Conclusion: It is suggested that the risks of CHBR and HP during earthquakes are the same, and some issues such as design, economy, and technical issues play a greater role in contractors’ selection of the system.
