Authors:   ,   Universidad Peruana de Ciencias Aplicadas (UPC), León Martell Daphne Reyna de Jesús
Published: November 2020

La responsabilidad social empresarial es un concepto que guía el comportamiento de las organizaciones y eleva la competitividad - reduce riesgos, incrementa la motivación, cuida al medio ambiente - y se preocupa en las percepciones de los diferentes grupos de interés (Argenti, 2014; Díaz, Filomeno & Rizo Patrón, 2007). En ese proceso la comunicación cumple un rol fundamental, porque informa y genera consenso entre la comunidad y la empresa. Este estudio tuvo por objetivo analizar las percepciones de los pobladores de tres comunidades de la provincia de San Vicente de Cañete acerca de las estrategias de comunicación que utiliza una empresa del sector industrial como parte de su política de responsabilidad social. La metodología de investigación utiliza el paradigma naturalista y enfoque cualitativo. Se aplicaron 11 entrevistas en profundidad, 2 de ellas dirigidas a la organización y 9 a las comunidades. Los pobladores, en su mayoría, tienen la percepción de que los medios empleados por la empresa carecen de utilidad puesto que el lenguaje e información utilizada no resulta entendible. La empresa se centra en desplegar únicamente estrategias informativas y no realiza estudios post- entrega para conocer la aceptación de los medios empleados.

One of the main arrangements that aim to guarantee the Universities social integration is through networks. In Macaé, a city in the interior of the Rio de Janeiro State, the local government encouraged the scientific potential with cooperation between the various Higher Education Institutions (HEIs) located in the region, through the implementation of the Macaé City Observatory. This article aims to discuss the creation of an interinstitutional and intersectoral study and research center, with shared spaces for analysis and reflection. For that were opted for a practical research on the history of the nucleus for the intervention purpose. It was possible to verify that the sharing of physical spaces and the production of knowledge about different points of view occur with political, ideological, varied knowledge clashes, with the possibility of advances, sometimes inherent in the dialogue between people and institutions. In this process, it was noticed the incorporation of several actors - municipal managers, public agents, professors, students, private institutions representatives and society - streamlining the production and dissemination of knowledge with an emphasis on Macaé and the region.

Conclusion: Turning your head in the direction of the teacher or colleague's voice when speaking and having difficulty hearing what the teacher says when writing from the back were the major audiological changes.
VOICE ON QUANTITATIVE METHODS IN RISK MANAGEMENT BY AN AIR OPERATOR
Authors: MAKOWSKI Piotr
Published: November 2020

This article is devoted to the diagnosis of problems arising from risk management obligations under the safety management system implemented in civil organisations of certified air operators (carriers). Focus was on the use of quantitative methods in safety risk analysis. The idea of an approach to determine the probability of accidents and serious incidents based on the intensity of symptoms with lower consequences and risk factors as a function of time or number of performed air operations was proposed, based on Markov discrete processes [6,10-12,16]. The essence of this approach is explained by the mathematical model of Runway Excursion probability during landing operations. The concept of improvement of operators' cooperation in the exchange of information about safety indicators by profiling the organisation was presented. The last proposal concerns the construction of a comprehensive risk assessment indicator using a safety risk matrix.

Despite constant efforts to improve safety in the railway environment, various accidents and incidents happen, resulting in material damage and in the worst case, loss of human lives. This article emphasises the need for proper identification of risks, their constant monitoring, and evaluation of all causes that arise at railway crossings. Furthermore, this paper aims to apply the Reason model to the problems of railway crossings within the case study on the railway network in Slovakia. The timeliness of the problem lies in the possibility of preventing such issues in the operation of rail transport using this model. Prevention is an effective way of averting the serious consequences of accidents in the future.
REFINEMENT OF THE PARAMETERS OF A MATHEMATICAL MODEL OF QUADCOPTER DYNAMICS
Authors: PASHAYEV Adalat , SABZIEV Elkhan
Published: November 2020

Errors in the calculation of the parameters of quadcopter control models at design stage significantly change the desired aerodynamic properties of the drone and make it difficult to control its flight along the intended path. Therefore, to calculate the adequate operation modes of the blades, it becomes necessary to refine some parameters of the mathematical model of the drone as accurately as possible. This paper shows the possibility of using control parameters (rotational speed of the blades) and information received from navigation devices of the drone to refine the values of the parameters of the mathematical model of the drone. For this purpose, a mathematical model of a quadcopter is built, and the problem of refining the parameters of its dynamic model is investigated based on the information received from navigation devices and the control parameters in the initial period of its flight. From the results obtained from several consecutive measurements, a system of equations expressing a mathematical model is solved. The mean value of the corresponding solutions of the system of three-dimensional linear equations obtained at different time intervals is the refined value of the parameters.

Authors: RAHMAN Faysal Ibna
Published: November 2020

For transport planning and policy-making, visualising the relationship among attributes; gender, education, occupation, age with travel pattern and mode choice is important. Household Interview Survey (HIS) is one of the major inputs in transport study which contains information about travel and demographic characteristics. From the analysis of 28,235 households in Dhaka city, this study represents the social demographic characteristic of Dhaka city based on the household survey. It was found that 89.79% of dwellers make double trips in a day and the trip rate per trip maker is 2.16, where 14% of total trips are generated at morning peak time between 7 to 8 am. The bus is the most preferable mode share and its contribution is about 35%. The scenario changed in a multimodal trip case and walking was the domination mode share with about 45% of total trips. Vehicle ownership had a vital rule in particular mode choice, especially in car and motorcycle household ownership case. Significant impact on travel patterns and mode choice criteria was found with gender, education, occupation, age, household income, trip purpose and time and vehicle ownership, which can help to formulate the strategic plan to solve the transport-related problem in Dhaka.

Authors: JILEK Petr , VRÁBEL Luboš
Published: November 2020

This paper deals with finding out the influence of the type of light source of car brake lights on the reaction time of the driver of the preceding vehicle. The driver’s reaction time was measured in the form of pressing the brake pedal depending on the lighting of brake lights on the leading vehicle. The measurement evaluation consists of a comparison of the phase shift between the brake light signal of the first vehicle and the brake light signal of the second vehicle. The experimental measurement was performed for five people using the classic light bulb, afterwards, an LED light source for the brake lights of the first vehicle. The records confirmed that the driver’s reaction time depends on many factors, with the source and intensity of the brake lights also playing an important role. Further, it affects the reaction time and the activity or inactivity of the rear sidelights. The reaction time of the driver of the preceding vehicle was extended with their activation.
SAMPLE STRUCTURAL SOLUTION FOR A CITY TRICYCLE WITH AN ADDITIONAL SOLAR DRIVE
Authors: KOWALSKI Sławomir
Published: November 2020

The everyday use of the bicycle is becoming increasingly common. People noticed the need to take care of both their health and the environment. The geographical location of Poland encourages cycling, which is the reason new kilometres of cycling routes are being built every year. This is associated with the rising interest in buying a bicycle. A conceptual tricycle with an additional electric drive powered by solar panels is presented in this article. The photovoltaic panel is installed on the basket roof. The electric motor may be used during an uphill ride and when the driver has run out of energy for pedalling. In the crank mechanism, there is a sensor which starts the motor when a small foot pressing force on the pedal is detected. The tricycle has an all-purpose structure, owing to which the seat mounted in the basket can be easily replaced with a double seat, a shopping bin or a child's safety seat. The tricycle may be used by both private persons and companies involved in tourist transport. The cost of the structural details of the tricycle suggested in this article does vary considerably from standard electric bikes, however, that solution has several important advantages, which may be decisive in the purchase of this solution.
A control algorithm for joint flight of a group of drones
Authors: SABZIEV Elkhan
Published: November 2020

Using drones in groups in the military field is not a novel idea. A massive attack by a large amount of equipment is known to be very difficult to prevent. Therefore, it is a good tactic to sacrifice some of the relatively cheap drones to destroy special enemy targets in a massive attack. This raises the issue of joint control of the behaviour of a group of drones. This paper proposes a System of Systems ideology-based decision-making system that allows to individually control each drone in a group flight. An algorithm is developed that allows controlling drones by controlling their speed.
Autonomous transmission control of a 2017 Yamaha Grizzly 700 all-terrain vehicle
Authors: WHEATLEY Greg , POPOOLA Samuel
Published: November 2020

Investigation on a designed and modified standard automatic transmission for a 2017 Yamaha Grizzly All-Terrain Vehicle was carried out to allow it to be controlled remotely and autonomously while maintaining its ability to be manually operated. The vehicle is a part of a project named AutoWeed. This project aims at developing a vehicle which can be used in the Australian outback to control and eradicate weeds. Preliminary tests were conducted on the vehicle to determine the performance parameters required to replace the movement supplied by the operator. Several devices used to achieve this motion were explored. It was concluded that the Motion Dynamics HB-DJ806 - LALI10010 electromechanical linear actuator be used as a proof of concept device for this application. This device is capable of exerting 200 N at 35 mm/seconds. It has a stroke length of 50 mm and was powered by a 12V DC motor, which drew 3 amps at maximum load. Through testing, it was found that the selected actuator did not have enough stroke length to cycle through the five gears on the ATV. This error was rectified allowing the system to function as intended. To achieve a reliable design, however, the Linak LA14 actuator was purchased as a final design as it was stronger, faster and had feedback capabilities. Before procurement, the new actuator was digitally modelled using SolidWorks 2017 and 3D printed to confirm the mounting position and method. An ANSYS FEA was conducted on all the custom-made components including the actuator bracket and mounting plate to ensure reliability. The bracket model was manufactured using 3D printing from ABS. It was recommended that for reliability, the bracket should be constructed from a stronger material such as aluminium. The results gained from testing proved that the autonomous transmission system implemented was reliable and repeatable. This was justified as the system achieved a 100% success rate when cycling through gears.
Tension force equalizer in a rope system using a proximity sensor
Authors: HRABOVSKÝ Leopold
Published: November 2020

Different values of tension forces in the load-bearing ropes of elevators, which push the rope into the grooves of the traction discs with different pressure, are the cause of uneven wear of the grooves of the traction discs under operating conditions. Current technical standards in the EU stipulate that the load suspended on load-bearing ropes be evenly distributed to all ropes used, using one of the many construction designs for tension force equalizers in the rope system. The main subject and primary objective of this paper are to present the construction design, 3D model and produced device of one of four produced prototypes, which were constructed in the “Research and Testing Laboratory”, and allow setting of differing values of tension forces in the system of ropes of a traction elevator, to values of the same size. Laboratory measurements were performed on the produced device, which enables the detection of tension forces in ropes and the magnitude of these forces in the required period to be graphically displayed on a PC. The prototype tension force equalizer can show the functionality and practical applicability of the procedure of balancing the levels of tension forces, which are of unequal strengths at the start of the laboratory measurement.

Published: November 2020

Fluoride is one of the few chemical contaminants in drinking water, even
though; it is known as an essential chemical component in water due to its beneficial effect
at a very low concentration. However, when present excessively in drinking water it has
detrimental effects on human health in terms of the prevalence of dental caries, skeletal
fluorosis and bone fractures. Endemic fluorosis, especially dental mottling and discoloration
has been prevalent in many parts of Eritrea. However, no well-established study has been
carried out to ascertain the fluoride content in the groundwater of the affected villages,
except a couple of researches conducted to estimate fluoride level in drinking water of the
villages around Keren and Elabered, where dental mottling and fluorosis is prevalent.
According to the researches the fluoride level in the underground water was found to be
higher than the maximum WHO limit of 1.5 mg/L. Butthe fluoride content of other places
(villages) with endemic dental fluorosis has not been determined and documented, and
therefore it is necessary to conduct this research in the affected areas to ascertain the fluoride
level in the drinking water of the community and compare it with the WHO standards.

Published: November 2020

The problems faced by the various industries are high energy consumption which
further increases the cost of production followed by reduced productivity and conversion, longer
residence time, and pollution caused by industrial waste. Many researchers have found various
alternative pathways to overcome these drawbacks. The same products were obtained in a better
way by process intensification. Any process can be intensified either by introducing entirely a
new process or by combing two or more conventional methods to form a new hybrid process e.greactive
distillation, micro-reactors, etc. Due to an increase in population and less availability of
land, reducing the chemical plant footprints is highly appreciable which is possible by process
intensification. In this paper, we have reviewed the majority of the processes that have been
intensified into a new process such as bioprocesses, extraction, distillation, leaching, Biofuels
production, Desalination, etc.

Oxidative stress may lead to a number of diseases such as atherosclerosis, nephrotoxicity,
liver cirrhosis, cancers, diabetes, and Alzheimer disease. Medicinal plants are an important source of
antioxidants. Therefore, the antioxidant potential of Cetraria islandica was evaluated in this work. The
coarse powder of leaf of Cetraria islandica was extracted in Soxhlet apparatus, with ethanol (90%) and
ethanolic extract of Cetraria islandica (EECI) was further processed for phytochemical screening, total
phenol content, total flavonoid content, and various in vitro antioxidant assays. The phytochemicals
present in EECI were glycosides, carbohydrates, triterpenoids, proteins and amino acids, gums and
mucilages, and flavonoids. The content of extractives was 8.3 mg/ml for Cetraria islandica еxtract 70%.
The content of polyphenolic compounds in terms of per head acid was the highest for the sample of 70%
and amounted to 0.586 mg/ml, and the content of flavonoids per standard solution quercetin - 0,012
mg/ml - also for 70% extract. By DPPH, the percentage of radicals of absorbing activity for 70% of the
extract was 86%, and the antiradical activity of 0,417, indicating a sufficiently high rate of Cetraria
islandica antioxidant activity at such a concentration of ethanol. The tested extracts showed next results
by FRAP assay: 486 μmol/L (EE96) 135 μmol/L (EE70) and 158 μmol/L (EE40). ABTS method showed
the highest result of the extract of Cetraria islandica 40%. The obtained results confirmed the high
potential of the extracts as a source of phenolic compounds, in particular flavonoids.

Authors:   Mindanao State University - Lanao National College of Arts and Trades, Tabao Shamseda Azis
Published: November 2020

There is no denying that professionals, including teachers, need to develop their knowledge and skills to be able to deliver their duties exemplarily. As expected, school heads should be supportive of the teachers’ quest. Hence, this study ventured to determine the practices of school heads that foster teachers’ professional development in terms of four aspects: (1) provisions of opportunities for professional growth; (2) assessment of teachers’ training needs; (3) conduct of in-service trainings; and (4) financial support. The investigation also included assessing the teachers’ development in terms of pedagogical knowledge and skills. A total of 172 teachers from seven (7) public high schools representing nine (9) districts of Marawi City, Philippines participated in this study. Data were collected through a survey questionnaire constructed based on the indicators of the Performance Appraisal System for School Administrators under Staff Development and the National Competency-Based Teachers Standards (NCBTS). Based on the findings, the respondents disclosed that their school heads show only moderate support for the first three aspects of professional development, with conducting of in-service trainings receiving the highest support among them. However, financial support for teachers’ professional development was low due to the lack of funds for public schools. These led to the conclusion that professional development is difficult to some teachers, especially in the context of the study, because school heads do not fully support them. Conspicuously, some impeding factors are behind this phenomenon, and immediate solutions are imperative to address such hindrances.

This research originated from a phenomenon that shows the low ability of students to think logically. This study aims to provide solutions to improve students' logical thinking skills by using discovery learning with truth or dare techniques. This type of research is a quasi-experimental design with a two-group pretest-posttest. The data were collected using a pre-test and post-test of students' logical thinking skills. The population in this study were students of class VII SMPN 5 Ponorogo. Those who were randomly selected as samples were class VII-F as the experimental class and class VII-I as the control class. Furthermore, data analysis was performed using the t-test. The results showed that the effectiveness of the discovery learning model of truth or dare learning technique with conventional learning has a significant difference. The ability to think logically between students who use the Discovery Learning learning model truth or dare technique is higher than the logical thinking skills of students who use conventional learning. The use of this learning model provides the opportunity for students to find concepts related to the material independently. As a result, students can hone and optimize their logical thinking skills to solve the problems they face during the learning process.

Published: November 2020

The objective of this investigation was to investigate the content, viscosity, and major functional groups of the native alginates extracted from 4 alginophytes collected from the Red Sea coast of Sudan in order to evaluate the quality of the polymer for potential applications. The content of the polymer ranged from 7.99±2.60% to 19.1±1.62% based on dry weight in the 4 seaweeds. The peak characteristics of the major functional groups of alginates were identified between 3469.70 cm-1 to 451.31 cm-1. These peaks specify the presence of hydroxyl (OH), carbonyl (C=O), and carboxyl (COOH) groups, respectively. The M/G ratios of the alginate extracted from the Sudanese brown macroalgae are ≤ 1 indicating that the proportion of guluronic acid is slightly greater than the mannuronic acid. The alginate with highest viscosity was that of Padina pavonica (Linnaeus) Thivy (190.7±1.14 mPa.s) followed by Dictyota dichotoma (Hudson) J.V.Lamouroux (146.96±1.2 mPa.s), Turbinaria ornata (Turner) J.Agardh (140.1±1.14 mPa.s), and Hormophysa cuneiformis (J.F.Gmelin) P.C.Silva (109±0.6 mPa.s). The values of the parameters of the native alginates extracted from the Sudanese macroalgae are comparatively in conformity with values reported for some species from similar geographical regions. These values indicated that the present biopolymer is of a potential with regard to pharmaceutical and industrial applications.

Published: November 2020

Studying the second language (L2) was happens around the world because of some reasons such as education. Studying another language can be important in intellectual human activities after studying first language (L1). However using L2 is quite hard because some of them use L2 just for some their activities, not for the whole of their activities, such as students who use English only when studying English subject only or on the contrary. Nowadays, some people use two language at the same time, which is called code mixing. The use of two codes for communication can help them to make clear their explanation from another language that they used. The purpose of this research is concerning on the use of code mixing in college students’ presentation in Intercultural Communication class. Apart from that, there is an attempt to find out the language dominate in their presentation, the reasons of code mixing use in their presentation and the response of the audience about code mixing in presentation. The Method use is qualitative by using class presentation as the instrument, the writer collected the data of the college students’ presentation, questionnaire to the audience and interview to the presenters. The research findings showed that the languages dominate in the presentation are English language and Bahasa Indonesia equally. The reasons’ student in use code mixing is to make the explanation clear, and the response of the audience is 56.83% of the students give positive response in using code mixing of the presenter.

This research examines TV advertisements for beauty products on local TV from the perspective of Critical Discourse Analysis. This research mainly focuses on the use of language in beauty advertisements and the strategies used by advertisers to manipulate and influence their customers. This analysis is based on Fairclough's three-dimensional framework, which shows how the ideology of “beauty” is produced and reproduced through advertisements on TV. Qualitative research was conducted on beauty product advertisements from ten TV advertisements for beauty products in 2019. The advertisements taken and analyzed were advertisements for facial beauty products from various brands and types. The findings suggest that advertisers use a variety of strategies to manipulate women. Advertising language is used to control people's thoughts. The better the words the advertisers used to manipulate the viewers, the better reaction that they will get from the viewers. This research shows advertisers are not only promoting their products but highlighting society's standards of beauty and cultural values into the viewers’ lifestyle and how the TV advertisements have shaped the beauty ideology of social practice in Indonesia.

The present study evaluates the reliability of the latest generation five best general circulation models (GCMs) under the Coupled Model Intercomparison Project Phase 5 (CMIP5) and their corresponding regional climate models (RCMs) of Coordinated Regional Climate Downscaling Experiment (CORDEX) for the Bundelkhand region in central India. The study is performed on a microscale due to frequent drought events and more climate susceptibility in the study region. Observed daily precipitation data of 35 years (1971–2005) from the Indian Meteorological Department (IMD) have been chosen to check the performance of the models. Bilinear interpolation has been adopted to prepare all the data to obtain them on a common grid platform at a half-degree (0.5° × 0.5°) resolution. The data of the models have been bias-corrected using quantile mapping. Uncertainty of the models has been assessed using Nash–Sutcliffe efficiency (NSE), coefficient of determination (r2) and a modified method known as skill score (SS). The study concluded that the bias-corrected GCMs played a better role than the CORDEX RCMs for the Bundelkhand region. Earth System Model, ESM-2M of the Geophysical Fluid Dynamics Laboratory (GFDL) has shown better accuracy than all the CORDEX RCMs and their driving GCMs for the study region.

Medium- and long-term runoff forecasting has always been a problem, especially in the wet season. Forecasting performance can be improved using complementary ensemble empirical mode decomposition (CEEMD) to produce clearer signals as model inputs. In the forecasting models based on CEEMD, the entire time series is decomposed into several sub-series, each sub-series is divided into training and validation datasets and forecasted by some common models, such as least squares support vector machine (LSSVM), and finally an ensemble forecasting result is obtained by summing the forecasted results of each sub-series. This model was applied to forecast the inflow runoff of the Shitouxia Reservoir (STX Reservoir). The forecasting results show that the Nash efficiency coefficient of the LSSVM model is 0.815, and the Nash efficiency coefficient of the CEEMD-LSSVM model is 0.954, an increase of 13.9%. The root mean square error value is reduced from 20.654 to 10.235, a decrease of 50.4%. The runoff forecasting performance can be effectively improved by applying the CEEMD-LSSVM model. When analyzing the annual runoff forecasting results month by month, it was found that the forecasting results for November to April were unsatisfactory compared results from the nearest neighbor bootstrapping regressive (NNBR) model, which was more suitable for the dry season, but the forecasting results for May to October improved significantly. This also proves that the CEEMD-LSSVM model has a great advantage in the forecasting of inflow runoff during the wet season. In the optimized operation of reservoirs, the forecasting result of inflow runoff in the wet season is more important than in the dry season. Therefore, when forecasting annual runoff month by month, the CEEMD-LSSVM model is recommended for the wet season combined with the NNBR model for the dry season.
Metals removal from automobile workshop stormwater runoff using rice husk, GAC and gravel filtration
Authors: Ataguba Clement Oguche , Brink Isobel
Published: November 2020

The efficiency of combined filtration media consisting of rice husk (RH), granular activated carbon (GAC) and gravel (GR) for the removal of metals cadmium, copper, lead and iron from stormwater runoff emanating from automobile workshops in Nigeria was investigated. Stormwater runoff samples were collected from five sites over a period of nine (9) weeks and filtered using two filter combinations, GAC – RH, GR – GAC as well as a RH-only filter. All the filters removed metals. Highest average singular metals removals were: approximately 74% copper for GR – GAC; 70% lead for RH, 67% iron for GAC – RH and 46% cadmium for GAC – RH. Average metals removal efficiencies (all metals combined) were GAC – RH 61%, GR – GAC 52% and RH-only 46%. The combined filter materials therefore showed better metals removal efficiencies than the RH-only filter. Further filtration of metals polluted stormwater would be required to lower the average metals concentration to meet local and international discharge standards. Future research into low cost modifications towards optimising the filter materials to improve metals removal efficiencies is recommended.
Forecasting Confidence Intervals: Sensitivity Respecting Panel-Data Point-Value Replacement Protocols
Authors: Heilig Frank , Lusk Edward J.
Published: November 2020

In the practice of Time Series [TS] forecasting there are very often situations where it is prudent to modify certain “outlier” values in the TS-Panel. A simple modification protocol is to replace selected TS-points by the Average of their adjacent Near-Neighbor-points [ANN]. Thus, a research question, not previously addressed and thus of interest, is: Are ANN-TS modifications balanced—50% of the time provoking OLS-forecasting variation, thus reducing the predicative acuity of the 95% Confidence Intervals; and, by symmetry, 50% of the time smoothing resulting in more predicative resolution. Research Plan To address this question, we: (i) collected accounting information to be forecasted from firms on the Bloomberg™ terminals for Income Statement and Balance Sheet sensitive variables, (ii) formed three ANN-modifications, and (iii) computed 95% Confidence Intervals using the firm-Panel and the three modified Panels. Results Regarding the research question, surprisingly the ANN-replacement protocols were not balanced. In fact, about 2/3 of the time the ANN was smoothing in nature, and thus about 1/3 of the time the ANN-protocol provoked OLS-variation. We discuss the important implication of this result for forecasting in the economic context.
A Review of the Influence of Rural Public Goods Supply on Rural Residents’ Consumption—A Case Study of 2009-2019
Authors: Yinlei Yang
Published: November 2020

The supply of rural public goods and the consumption of rural residents are not only an important symbol of the quality of life of rural residents, but also reflect the satisfaction of the majority of rural residents to a better life. At the same time, the supply of rural public goods and the consumption of rural residents are also the “engine” and “ballast stone”. The supply of rural public goods and the consumption of rural residents are the “Chinese experience” to solve the crisis. In the early days of the founding of the people’s Republic of China, the reform and opening up of the production package, the soft landing of the 2008 financial tsunami was a solution to the crisis by adjusting the supply of rural public goods. In the face of the complex situation of the current international economy and the influence of the epidemic situation, a new development pattern with the large domestic circulation as the main body and the domestic and international double circulation promoting each other can not only resolve the overproduction of the city, but also realize the redistribution of urban and rural resources by stimulating consumption. The research on the supply of rural public goods in China has been fruitful. From 2009 to 2019, there were 2729 articles on the supply of rural public goods and the consumption of rural residents.
