The pedagogical conditions of future primary school teacher training for the formation of primary school pupils’ social competence are determined in the article. They have been represented as a set of interrelated circumstances based on a focused and systematic coordination of activities of subjects of educational interactions in higher educational establishments, in order to improve the future primary school teacher training to the formation of social competence of primary school pupils. The essence and methods of implementation of one of them, namely the formation of motivational sphere of future teachers as for the formation of social competence of primary school pupils based on attributive approach have been studied.

The analysis of the ideas of foreign psychologists that reveal the influence of motives of learning and achievements of the educational process efficiency in secondary and higher educational institutions was made. The psychologists’ generalization concerning the peculiarities of the attributive style (optimistic, pessimistic) of students was presented as the characteristics of their personality that has as individual expression and can be measured by means of specific diagnostic techniques and also changed with the help of advisory accompaniment or support.

The basic directions of attributive approach introduction in training the future primary school teachers on the basis of principles of teacher’s behavior introduced by B. Takman, were determined.

The attention was focused on the feasibility of developing and implementing the program of motivational sphere development of primary school teachers to the formation of social competence of primary school pupils. Based on the conducted analysis, the main directions of its realization were summarized, such as: the work with students on the optimistic attributive style development, high motivation of achievement and self-determination, increasing motivation to personal and professional self-improvement in a future profession, support of positive results of motivating development etc.

It is concluded that the use of attributive approach in general will contribute to the enhancement of students’ learning motivation, prevention of their state of helplessness that may occur as a result of their own frustration. It also may help to learn the skills of the own results evaluation and planning of their actions based on the high achievement motivation.

Dirty hands will be a source of disease. Soap is a pharmaceutical preparation used to maintain health. Celery (Apium graveolens L.) is a plant of the Apiaceae tribe with a distinctive menthol aroma. This study aimed to determine the inhibitory power of celery leaf extract formulation (Apium graveolens L.) as an antibacterial hand-washing soap. This research method is a type of experimental research. The stages of the research were collecting samples, identifying plants, making simplicia, characterizing simplicia, screening phytochemicals, making extracts and making hand soap formulations of celery leaf extract (Apium graveolens L) at concentrations of 5%, 10%, 15% and antibacterial testing of celery leaves, against Escherichia coli bacteria. The results showed the celery leaf extract soap formulation contained phytochemical compounds of flavonoids, tannins and saponins. The organoleptic test found that the best soap formulation was the F2 formulation with a concentration of 10% at an average level of preference value, namely 3.67 for colour, 3.27 for aroma, and 3.80 for texture. The homogeneity test performed showed that all formulations produced soap with good homogeneity. The height and stability test of the resulting celery extract soap foam ranged from 61-71 mm. The irritation test of the resulting celery extract soap also showed no irritation for all the formulations. The value of the antibacterial activity test found that the F1 formulation showed antibacterial activity with an inhibition zone diameter of 3 (weak), F2 with an inhibition zone of 9 (moderate) and F3 with the antibacterial activity of 12 (strong).

DNA origami is a rapidly emerging nanotechnology that enables researchers to create nanostructures with unprecedented geometric precision that have tremendous potential to advance a variety of fields, including molecular sensing, robotics, and nanomedicine. Hence, many students could benefit from exposure to basic knowledge of DNA origami nanotechnology. However, due to the complexity of design, cost of materials, and cost of equipment, experiments with DNA origami have been limited mainly to research institutions in graduate-level laboratories with significant prior expertise and well-equipped laboratories. This work focuses on overcoming critical barriers to translating DNA origami methods to educational laboratory settings. In particular, we present a streamlined protocol for fabrication and analysis of DNA origami nanostructures that can be carried out within a 2-h laboratory course using low-cost equipment, much of which is readily available in educational laboratories and science classrooms. We focus this educational experiment module on a DNA origami nanorod structure that was previously developed for drug delivery applications. In addition to fabricating nanostructures, we demonstrate a protocol for students to analyze structures via gel electrophoresis using classroom-ready gel equipment. These results establish a basis to expose students to DNA origami nanotechnology and can enable or reinforce valuable learning milestones in fields such as biomaterials, biological engineering, and nanomedicine. Furthermore, introducing students to DNA nanotechnology and related fields can also have the potential to increase interest and future involvement by young students.

Re-defining the Rural-urban: Discovering Spatial Patterns of Chinese Rural Development
Authors:   North Carolina State University, Lok Leslie
Published: May 2023

The perception of the rural has shifted and has been incarnated with various narratives and policies of urbanization since the founding of the People’s Republic of China. Although the most intense periods of rapid urbanization have been mainly driven by the incessant development of cities and megacities, the countryside has played a central role in the country’s urbanization process through in situ transformations of towns and villages as integral parts of urban economics, the industrialization of the countryside, and the steady conurbation of rural towns and urban centers1. Reaching 58.52%2 of urban population in 2017 and with the goal of continuing to urbanize its population to 75% by 2025, the growth of rural villages and townships emerged as the predominant context for urbanization under the 2005 New Socialist Countryside policies. The rural context, and in particular, the ambiguous zones of rural-urban, have shifted to the focal point of urbanization. More recently in 2014, China’s National New Townization Plan directs the focus to develop small cities, towns, and villages. The process of townization engages a wide range of territorial landscapes that are neither distinctly urban nor distinctly rural. With much at stake in the transformation of the rural- urban context, there lacks a clear spatial characterization and definition which defines the multivalent landscape. First by outlining the changing narratives and policy phases of rural development, the paper aims to identify limitations in the current administrative and binary classification of the urban cities and rural villages. By further analyzing five case study cities, the paper attempts to reveal emerged and collaged architectural and growth patterns of the rural-urban context, to provide methods of mapping the transformation of their spatial structure at the territorial scale, and lastly, to argue for the importance of the rural-urban as a valuable condition for designing better urbanization models.
Beyond the Centralized Paradigm: Retrofitting Cities with Decentralized Energy, Transportation, and Water
Authors:   University of Arizona, Crosson Courtney
Published: May 2023

Our cities will increasingly rely on decentralized infrastructure for the collection, storage, and distribution of renewable re-sources (e.g. rainwater harvesting, photovoltaic micro-grids, electric autonomous vehicle hubs). Existing centralized transportation, energy, and water systems will need to be retrofitted to integrate these new decentralized system tech-nologies. How this will occur is yet to be fully understood. To maximize benefit and minimize disruption, models for the integration of these three systems and coordinated retrofit of existing infrastructure is needed. This paper provides a replicable model for academia to join with practice and local governments to fill this knowledge gap in one mid-sized city toward future policy adoption and implementation. This paper presents three adaptive solutions of how to accomplish new sustainable infrastructure beyond the existing centralized paradigms for transportation, energy, and water.
Apendicitis aguda como manifestación clínica secundaria a metástasis de un carcinoma de células escamosas del cérvix. Reporte de caso
Authors: Parra Medina Rafael , López-Correa Patricia , Pacheco Marwil , Romero Rojas Alfredo Ernesto
Published: May 2023

Las neoplasias primarias y secundarias del apéndice son raras y se encuentran en aproximadamente el 1% de las muestras de apendicectomía quirúrgica. El carcinoma de células escamosas del cuello uterino (CECU) se disemina principalmente por invasión local directa de los tejidos y por vía linfática, y con menor frecuencia a través de los vasos sanguíneos. La diseminación de CECU por vía linfática ocurre de manera temprana y está presente en el 25-50% de los pacientes con carcinomas en estadio IB y II. Presentamos el caso de una mujer de 31 años con antecedente de CECU estadio IVB. La paciente recibió radioterapia paliativa (3 Gy fraccionada para un total de 30 Gy) y posteriormente quimioterapia (cisplatino 50 mg/m2 IV y paclitaxel 175 mg/m2 IV). Dos meses después del inicio de la terapia con radioterapia y quimioterapia, ingresó al hospital presentando dolor abdominal, fiebre y vómitos. La laparotomía reveló apendicitis perforada y un absceso intraabdominal sin evidencia de compromiso de ovario o trompa de Falopio. El examen histopatológico del espécimen extirpado evidenció un proceso inflamatorio agudo severo y la presencia de CECU. En conclusión, describimos el segundo caso de apendicitis aguda secundaria a CECU metastásico, publicado en la literatura médica. Este es un caso interesante debido a la rareza de la apendicitis aguda asociada con el cáncer de cuello uterino metastásico en el apéndice a través de los vasos linfáticos. La historia previa de CECU tuvo un papel importante para definir el diagnóstico histopatológico.

Authors: Giraldo Osorio Alexandra , Ruano-Ravina Alberto , Arias Ortiz Nelson Enrique , Pérez Ríos Mónica
Published: May 2023

En Colombia, los estudios y encuestas poblacionales han incorporado preguntas sobre consumo de tabaco en adultos, aunque no existe un cuestionario estandarizado. Se buscó identificar los estudios o encuestas que han caracterizado el consumo de tabaco en adultos en Colombia y analizar las variables que se incluyen con ese fin, según su utilidad. Se revisaron las páginas web de organismos oficiales y se realizó una revisión narrativa de los estudios y encuestas publicados hasta febrero de 2022. Se identificaron 11 estudios o encuestas que incluyeron un número variable de preguntas sobre consumo de tabaco, todos permitieron estimar prevalencias de fumadores actuales, pero no las de exfumadores. La edad objetivo del estudio no es homogénea, el ámbito es nacional en la mayoría y muestran una enorme variabilidad en las preguntas. Estandarizar los instrumentos que permiten estimar la prevalencia de consumo de tabaco debería ser una prioridad en Colombia.

Objetivo. Analizar las diferencias en la presentación de variables clínico-patológicas, de acuerdo con la expresión proteica de GRB7, en tumores HER2 positivos en mujeres colombianas con cáncer de mama invasivo, diagnosticado entre los años 2013 y 2015 en el Instituto Nacional de Cancerología E.S.E (INC).
Métodos. Se incluyeron 158 pacientes con diagnóstico confirmado de cáncer de mama ductal invasivo. Se evaluó la expresión de los receptores hormonales (receptor de estrógeno (RE) y de progesterona (RP)), HER2, Ki67 y GRB7, mediante inmunohistoquímica (IHQ), y a partir de estos, se clasificaron los tumores en subtipos intrínsecos. Los análisis estadísticos incluyeron las pruebas de Chi-cuadrado/test exacto de Fisher para las variables categóricas, y la prueba U Mann Whitney/ Kruskal Wallis para las variables cuantitativas. Se evaluó la supervivencia global (SG) y libre de enfermedad (SLR) según la coexpresión de HER2/GRB7 usando el método de Kaplan-Meier y el test de log-rank.
Resultados. La expresión de GRB7 se observó exclusivamente en tumores HER2-positivos (luminal B/HER2+ y HER2-enriquecidos: p<0,001). Los casos HER2+/GRB7+ mostraron una mayor expresión de Ki67 (40% vs. 27,5%, p=0,029), pero una tendencia a presentar un menor tamaño tumoral (30 mm vs. 51 mm, p=0,097), comparado con los tumores HER2+/GRB7-. No obstante, no se observaron diferencias en la supervivencia según la coexpresión de HER2/GRB7 (SG: p=0,6; SLR: p=0,07).
Conclusiones. En nuestra muestra de estudio, la expresión de GRB7 en tumores HER2+ no se asoció con características clínico-patológicas de pronóstico desfavorable.

The State of Public Health in Constituent Entities of the Russian Federation
in Times of a Large-Scale Epidemiological Challenge: The Example
of the COVID-19 Pandemic

Published: May 2023

Introduction: In 2020–2022, Russia, like the rest of the world, faced the COVID-19 pandemic. The necessity to overcome its challenges has led to the expansion of powers of the regions. To improve public policy, it is expedient to evaluate the effectiveness of measures taken by the regions for public health preservation. Such an evaluation is proposed to be carried out using the public health index, which requires the development of appropriate methodological approaches.
Objective: To develop and test a methodological approach to analyzing the effectiveness of public policy measures in terms of preserving public health. Materials and methods: This work continues a series of studies on establishing the public health index in the Russian Federation, which has already developed an approach to calculating this indicator in view of medical and social resources of the population. The approach is based on the recommendations of the World Health Organization standard "The Urban
Health Index". The evaluation of the effectiveness of public policy measures involves the implementation of several stages for calculating the public health index and the classification of Russian regions depending on the degree of its change for
2019-2022. When performing calculations, correlation analysis is used to identify indicators that do not contradict each other. Through the normalization of indicators, as well as the calculation of average geometric values, the calculation of the public health index is carried out. The data for calculating the public health index are taken from the website of Rosstat and the Ministry of Health of Russia.
Results: We established deterioration of public health indicators in most regions. We believe that this finding is primarily related to the COVID-19 pandemic as a large–scale challenge. In 2022, the public health index for the Russian Federation has decreased by 13.15 % compared with 2019. The largest decline has been observed in the Saratov Region (69.14 %). At the same time, an increase in the public health index has been registered in several regions, e.g. by 6 % over the study period in the Tyumen Region.
Conclusion: The analysis of the components of the public health index makes it possible to ascertain the cause of public health worsening in the region and to assess its determinants. Having classified the regions, it is important to identify the determinants of public health that can be influenced through public policy instruments.

Published: May 2023

For the problem of lacking reliable parameters during simulation analysis of the crushed corn stalk (CCS) micro-comminution process with gas-solid coupling method, the simulation parameters are calibrated using a combination of physical measurements and virtual experiments with CCS as the research object. The intrinsic parameters of CCS are obtained by physical experiment, and the stacking test is carried out by cylinder lifting method, and the actual angle of repose(AoR) is obtained as 44.12° by fitting the boundary line with Matlab software; the discrete element model of CCS is established, and the virtual stacking test is carried out by EDEM software; CCS-CCS dynamic friction coefficient, CCS-CCS static friction coefficient and JKR (Johnson-Kendall-Roberts) surface energy are identified as the parameters with significant effects on the AoR by Plackett-Burman test; the steepest climb test is leveraged to determine the center of response surface analysis; the quadratic polynomial regression model of the simulation parameters and the AoR is established by the Box-Behnken test using the AoR as the evaluation index, and the optimal combination of the significant parameters are obtained as follows: the CCS-CCS dynamic friction coefficient is 0.55, the CCS-CCS static friction coefficient is 0.14, and the JKR surface energy is 0.12; the AoR verification test is conducted based on the optimal combination of the significant parameters The results show that the AoR of the CCS is 43.82°, which is 0.68% of the actual AoR, indicating that the parameter combination is reliable. The data obtained in this research can provide corresponding simulation parameters for CCS discrete element simulation and the development of straw micro-crushing equipment.

Published: May 2023

In the buckwheat industry, buckwheat sizing effect has played a significant role in the subsequent hulling effect and food quality in its deep processing. In order to study the influence of inclination angle of linear vibrating screen on buckwheat sizing effect, EDEM was used for numerical simulation of sizing process with the inclination angle of the screen separately at 2°, 3°, 4°, and 5°. By observing particle distribution on the screen deck and calculating the different types of particles in various statistical areas, qualitative comparison and quantitative analysis on the conveying capability of the screen and the penetrating capability of particles at different inclination angles were made, and the results revealed that with the increase in the inclination angle of the screen, the conveying capability of the screen was enhanced, while particles became less capable of penetrating through the sieve. When the inclination angle was increased from 2° to 3°, the conveying capability of the screen was significantly improved, while the penetrating capability of particles on both screen decks was slightly reduced. By taking the penetrating capability of particles and the conveying capability of the screen into comprehensive consideration, it turned out that better sizing effect would be achieved at the inclination angle of 3o. Our research will provide a reference for optimizing the processing parameters during the vibrating separation of buckwheat.

Smart agriculture, which combines the Internet of Things (IoT) with agriculture, is the future of agricultural development. In China, manual irrigation is currently the dominant method for seedling irrigation management, but it is inefficient and can lead to water waste. To improve seedling quality and output, reduce labor costs, and conserve water resources, this paper presents a design for an IoT system that uses soil moisture detection and remote precision irrigation for seedlings. The system includes a STC12C5A60S2 microcontroller, an ESP8266-01S communication module, a PRISON PR-3000-ECTH-N01 soil temperature and humidity module, and a 12V water pump. The system is connected to the OneNET platform via the MQTT protocol of the Wi-Fi module and includes software modules for data processing, Wi-Fi communication, and relay control. The OneNET platform allows users to monitor and record real-time temperature and humidity data and switch between automatic and manual modes and seedling threshold types. The system was tested for 24 hours and collected 28,000 temperature and humidity data points every 3 seconds with a packet loss rate of less than 5%. The results show that the system is stable and reliable.

A study on the Li of 『Jian』 by Zheng Xuan
Authors:   The Society For Chinese Humanities In Korea, Jo Hae Jin
Published: May 2023

This thesis, through the study of Zheng Xuan's 『Jian』, was ultimately compared with the interpretation of hair poetry in order to trace the way of thinking of scholars of the Han Dynasty reflected in it. Since Zheng Xuan was well versed in rites, he inevitably quoted the three rites a lot in the process of interpreting 『Shijing』 as rites, and reflected the contents of rites in the commentary. Examples of commenting on the interpretation of the Book of Poetry from the perspective of ceremonies were analyzed in Zheng Xuan's 『Jian』. A new way of interpreting poetry, including the achievements of Han Confucian studies on the Book of Poetry, was presented. Zheng Xuan's 『Jian』 is to interpret the sutra with the sutra, which is the way of interpreting the sutras of Confucian scholars, with other sutras, with the exhortation of letters, with the interpretation of the sutras as the Buddhist scriptures, and with concrete events. All methods such as interpreting the sutra were properly used to interpret the sutra. He extensively quoted the Confucian classics and major historical sources, exerting a great influence on the Han Dynasty. Through the process of completing 『Zhuan』 and 『Xu』 in the Han Dynasty as the Confucian family's interpretation system of the scriptures began to be established from the early Qin period, the interpretation system of mother poems through Zheng Xuan's 『Jian』, and through the process of Zheng Xuan completing 『Jian』 It shows the process of gradual materialization. It played an important intermediate stage in the formation of the interpretation system of hair poetry. 『Jian』, which was annotated on 『Shijing』 by Zheng Xuan during the Donghan period, was developed based on the interpretation of 『Xu』 and 『Zhuan』, which are the interpretation systems of mother poetry, and is the most basic and important data in the study of poetry and scripture.

Gangguan Stres Pascatrauma Dan Panggilan Penginjilan: Sebuah Refleksi Teologis dan Psikologis dari Kitab Yunus
Authors: Hutagalung Stimson
Published: May 2023

Penginjilan adalah Amanat Agung dari Tuhan untuk setiap manusia. Amanat yang sama juga dimandatkan Tuhan untuk Yunus, namun Yunus menolak dengan berani panggilan Agung tersebut. Penelitian ini mencoba untuk mencari tahu mengapa Yunus “terlalu berani” menampik panggilan Agung Tuhan dan bertolak ke Tarsis? Dan mengapa kemudian dia bertukar haluan dari Tarsis ke Niniwe?. Penelitian ini menggunakan metode kualitatif dengan pendekatan deskriptif analisis melalui kajian literatur terhadap teks Alkitab dengan mengkaji sisi teologis dan psikologis Yunus melalui tiga tahap analisis. Sebagai kesimpulan, tindakan “terlalu berani” Yunus menampik panggilan Agung Tuhan diakibatkan oleh gangguan stres pasca trauma yang dialaminya bersama keluarga sejak ia kecil hingga dewasa selama invasi Suriah ke Israel Utara sehingga muncul sikap antagonisme intensnya terhadap Niniwe yang membuatnya menjauh dari Tuhan. Ketika gangguan stres pasca trauma yang dialami Yunus diobati dengan penyerahan sepenuhnya melalui doa, Yunus diberikan ketangguhan, ketabahan, dan ketegaran hati untuk mengabarkan berita keselamatan ke kota Niniwe.

More specifically, antennas are recognized as a vital technology to support the continuously growing demand for 5G/6G connectivity and data rates. In the development of wireless communication systems, an effective antenna design is critical. In this work, we present the design and modeling of a hexagonal microstrip antenna for using in ultra-wide band applications such as 5G mobile networks. The suggested antenna has a frequency range of 3.3 GHz to 4.5 GHz, dimensions of 20 mm × 14 mm, and is built on a FR-4 substrate, with a relative permittivity of 4.3, and of 1.6 mm in height. It is expected that this antenna will operate in two notched bands with resonance frequencies of 3.3 GHz and 4.5 GHz and a voltage standing wave ratio (VSWR) of less than 2. The proposed antenna, which has been expanded to be a multiple-input multiple-output (MIMO) antenna, was created and modeled using CST Microwave Studio. The comparison against the recent works is given to show the efficiency of the proposed design.

A p-type graphene–oxide–semiconductor (GOS) planar-type electron emission device holds promise as a photocathode with a high quantum efficiency (QE) for generating a high-speed modulated electron beam. We report the electron emission properties of a planar-type electron emission device based on a GOS structure using lightly doped p-type silicon as a substrate under laser light irradiation. The electron emission efficiency is 12% with and without laser light irradiation. The emission current shows a four-order of magnitude enhancement in the high field region compared to that in the dark, and a 0.3% QE is obtained without a negative electron affinity surface. This GOS device exhibits advanced photoassisted electron emission characteristics with high photosensitivity on the order of mA/W. The photoemission from the p-type GOS device shows a fast photoresponse with a rise time of less than 0.2 µs, which is the same as that of the current amplifier. By contrast, it shows a slow response of about 2.4 µs at the fall time, which is determined by the diffusion process of the photoexcited electrons in the bulk. The use of a highly doped p-type silicon substrate can be a practical route for further improvement.

Conventional mock circulatory loops (MCLs) cannot replicate realistic hemodynamic conditions without inducing blood trauma. This constrains in-vitro hemocompatibility examinations of blood pumps to static operating conditions that do not reflect clinical scenarios. This study aimed at developing an atraumatic MCL based on a hardware-in-the-loop concept (H-MCL) that enables hemocompatibility assessment under realistic hemodynamic conditions. The atraumatic H-MCL was designed for 450±50 ml of blood with the sole blood-contacting components being the polycarbonate reservoirs, the silicone/polyvinyl-chloride tubing and the blood pump under investigation. To account for inherent coupling effects a decoupling pressure control was derived by feedback linearization, whereas the level control was addressed by an optimization task to overcome periodic loss of controllability. The HeartMate 3 was showcased to evaluate the H-MCL’s accuracy at typical hemodynamic conditions and to demonstrate the H-MCL’s atraumatic properties. Pilot hemolysis experiments were conducted with bovine (n=2) and human (n=2) blood, and evaluated in terms of the normalized index of hemolysis (NIH). Typical hemodynamic scenarios of patients with full and partial support were replicated with marginal coupling effects and root mean square error (RMSE) of 1.74±1.37 mmHg and 0.94±0.83 mmHg, respectively, while the fluid level did not exceed a range of ±4% of its target value. The initial examinations of hemolysis demonstrated the atraumatic characteristics of the novel H-MCL, as evidenced by levels of NIH (bovine: 5.1-7.2mg/100L; human: 1.6-1.8mg/100L) that are consistent with those reported in existing literature. Collectively, these findings indicated the H-MCL’s potential for in-vitro hemocompatibiltiy assessment of blood pumps within realistic hemodynamic conditions.

Virtual synchronous machines (VSMs) have become popular solutions for grid-tied inverters, suited to work on AC-grids with an increasing share of distributed energy sources and storage. However, just like real synchronous machines, VSMs may experience power oscillations. Recently, a new damping concept called virtual friction (VF) has been proposed that makes use of real time communication between several inverters. VF introduces an additional damping torque in the swing equation of the VSM, proportional to the deviation of the virtual rotor frequency from the center of inertia (COI)-frequency. VF can apply high damping without imposing a strong response in the output power of the VSM during frequency transients. However, VF requires the transmission of frequencies over a communication network, which may suffer from transmission delays. We give an experimental proof of concept of VF both in an isolated microgrid and in grid connected operation of a 45kVA setup consisting of three VSMs realized by three-phase two-level IGBT-based inverters1. We consider continuous constant and discontinuous varying time delays and show theoretically and experimentally under what conditions delays can impact the output powers of the VSMs. Further, we show how to correctly estimate the COI-frequency with transmission delays using timestamps to align individual signals.

Efficient resource allocation strategies are pivotal in vehicular communications as connected devices steeply increase in scenarios with much more stringent requirements. In this work, we propose a deep reinforcement learning (DRL)-based sequential scheduling approach for sum-rate maximization in the uplink of intelligent reflecting surface (IRS)-assisted multiuser (MU) multiple-input multiple-output (MIMO) vehicular communications. We formulate the scheduling task as a partially observable Markov decision process (POMDP) and propose a novel stream-level sequential solution based on the proximal policy optimization (PPO) algorithm. We consider a realistic imperfect channel state information (ICSI) model and assess the proposal in several communication setups comprising both spatially uncorrelated and correlated links. Simulation results show that the proposed DRL-based sequential scheduling approach is a robust alternative to more computationally demanding benchmarks.

Papaya fruit is in great demand by people at home and abroad, thus proving that this one agricultural product has become a global need that is in great demand and sought after. To determine the papaya harvest based on the color of the fruit skin, the ripeness of the papaya starts from unripe, unripe (half-ripe) and overripe so that the researchers put forward an idea to answer the problem in determining the ripeness of papaya fruit, which is mostly done manually, still has some weaknesses and requires the process is quite long, has low accuracy and is inconsistent. Based on these problems, a system was created to classify the ripeness level of papaya by utilizing the HSV color features using the K-Nearest Neighbor (K-NN) algorithm. This classification uses image processing by utilizing MATLAB software to create a classification system with three classification classes, namely raw, half cooked and cooked. The classification generated using the K-Nearest Neighbor (K-NN) algorithm shows an accuracy of 86.6667%.
