Authors: Popovych Igor , Gozhenko Anatoliy , Bombushkar Igor , Anchev Anatoliy , Zukow Walery
Published: January 2023

Background. We previously showed that the factor structure of the relationships between the plasma levels of nitrogenous metabolites (uric acid, bilirubin, urea, and creatinine), on the one hand, and the parameters of anxiety and neuro-endocrine status, on the other hand, is significantly different in men and women of reproductive age and postmenopausal. The purpose of this study is to identify the metabolic and psycho-neuro-endocrine features of these three cohorts of people. Materials and methods. The object of observation were 31 males (24÷69 y) and 30 females, from among them 18 postmenopausal (45÷76 y) and 12 of reproductive age (30÷42 y), with dysfunction of neuro-endocrine-immune complex. In basal conditions we determined plasma levels of nitrogenous metabolites and adaptation hormones, estimated the severity of the trait and reactive anxiety, recorded the ongoing HRV and EEG. After 4 or 7 days, repeated testing was performed. Results. To achieve the goal, the registered parameters were subjected to discriminant analysis. Along with the quite expected nitrogenous metabolites, age, testosterone and calcitonin (both raw and sex- and age-standardized values), trait anxiety, Kerdö's Vegetative Index, one of the vagal markers (SDNN), as well as 10 EEG parameters emerged as characteristic features of the cohorts. In the information space of two discriminant roots, three cohorts are clearly demarcated. Conclusion. We interpret this as another proof of the existence of connections between nitrogenous metabolites and psycho-neuro-endocrine parameters in line with the concept of the functional-metabolic continuum.
Short-term scheduling of hybrid thermal, pumped-storage, and wind plants using firefly optimization algorithm
Authors: Moghaddas Alireza , Hosseini S. M. Hassan
Published: December 2022

This paper presents a novel method based on an enhanced firefly algorithm (EFA) to solve scheduling hybrid thermal, pumped-storage, and wind plants. Since the scheduling problem is inherently discrete, basic EFA and binary encoding/decoding techniques are used in the proposed EFA approach. Optimal power values of thermal and pumped-storage units are determined separately in the presence of uncertainty caused by wind speed. The proposed method is applied to a real plant, including four pumped-storage units, 34 thermal units with different characteristics, and one wind turbine plant. In addition, dynamic constraints of upstream and downstream sources and constraints regarding thermal and wind units are also considered for finding the optimal solution. In addition, the proposed EFA is successfully applied to a real plant, and the results are compared with those of the three available methods. The results show that the proposed method has converted to a more optimal cost than the other methods.
Ecpoc: an evolutionary computation-based proof of criteria consensus protocol

Published: December 2022

Recently, blockchain technology has been applied in many domains in our life. Blockchain networks typically utilize a consensus protocol to achieve consistency among network nodes in a decentralized environment. Delegated Proof of Stake (DPoS) is a popular mechanism adopted in many networks such as BitShares, EOS, and Cardano because of its speed and scalability advantages. However, votes that come from nodes on a DPoS network tend to support a set of specific nodes that have a greater chance of becoming block producers after voting rounds. Therefore, only a small group of nodes can be selected to become block producers. To address this issue, we propose a new protocol called Evolutionary Computation-based Proof of Criteria (ECPoC), which uses ten criteria to evaluate and select a new block procedure in each round. Next, a set of optimal weights used for maximizing the network’s decentralization level is identified through the use of evolutionary computation algorithms. The experimental results show that our consensus significantly enhances the degree of decentralization in the selection process of witness nodes compared to DPoS. As a result, ECPoC facilitates fairness between nodes and creates momentum for blockchain network development
Minimizing production cost for kendang djembe production through goal programming model
Authors: Puspanola Nabila , Sumiati Sumiati
Published: December 2022

Kendang djembe is a percussion instrument played by striking with the fingers and palms. The body of the kendang djembe is generally made of wood and shaped like a cup or mug, carved either by machine or traditionally only by hand. This problem affects the production costs, the employee working house, and the profit of kendang djembe. Customer orders and requirements determine the production process for kendang djembe. It leads to fluctuations in market demand, affecting production costs and the working hours of kendang djembe employees. As a result, employees work overtime when orders rush in, resulting in poor product finishes such as crude engraving and painting. This research aims to minimize the production cost of kendang djembe, maximize the employee working hours, and maximize the profit by using the goal programming method. Goal programming is applied to decide the number of kendang djembe, the minimum production cost, and the time for each kendang djembe. The result of this research is that CV. Maharani Abadi has to make 237 units of kendang djembe paintings, 1266 kendang djembe carvings, 870 kendang djembe painting carvings, and 91 kendang djembe deep carvings. CV. Maharani spent a production cost of Rp 399,413,400, with the employee working 1846.36 hours, and obtained a maximum profit of Rp 126,526,600. This research helps the company to avoid unprofitable options in the production process of kendang djembe.

Published: January 2023

ABSTRACT: The major goal of this project is to develop a saline drip detection and control system used to inject saline or intravenous fluids into a patient's veins. This project presents an IoT-based system to address issues such as fluid backflow, blood loss, and so on. Solution to concerns like fluid backflow and blood loss, among others. As a result, we devised the Automated Intravenous Drip Monitoring System. In this project, we utilize an Arduino-based microcontroller to manage the drop rate, detect tube obstruction, and warn the user when the drips are emptied. Here we are going to monitor the drip rate whether it is low or over, by using ultrasonic sensor. By using the MEMS motion sensor, we can also detect the patient's movement while taking drips after they have undergone some surgery or in ICU condition. In addition, we are going to estimate the possibilities of blood clotting in the veins of the patient. If motion is detected in the infusion hose, the sensors will alert the doctors or nurses with a buzzer and an LED light. The flow rate and infusion interruption problems were monitored by transmitting the data wirelessly via Bluetooth via their smart phones using mobile applications and computer-based applications. As a result, at the nurse's station, the developing system can closely monitor the drip infusion situation of numerous patients.

Published: January 2023

Non-ionic surfactants, poly oxyethylene sorbitan adipose acid esters (polysorbate), were used in this work to explore the consequence of temperature on CMC throughout a wide temperature range. The phase separation model is used to analyze the enthalpy and entropy of micelle conformation. The Du Nöuys ring was used to determine the results' face pressure. The CMC standards were derived after the strong break down in surfactant attention plots of face pressure vs. logarithms. The CMC at continuous temperature decreases as the chain length of the surfactants rises, which is completely connected to the reduction in hydrophilicity of the motes. Because of the lower possibility of hydrogen bond conformation on high temperatures, the CMC of each surfactant initially declines and then increases as the system temperature rises. As the temperature rises, the commencement of micellization tends to happen at a faster rate. The focus of this research is on the characterization of solubilization of drugs that aren't sufficiently responsive. Face pressure measurements for nonionic surfactant TritonX-100 were also taken in order to assess the solubilization features. In the presence of colourful organic detergent, the medium's opposition and the likely positions of SMX and TMP were also discussed. TritonX-100, a nonionic surfactant, was also tested. In the presence of colourful organic detergents, the medium's opposition and the likely position of SMX and TMP were also discussed.

Published: December 2022

The incidence of heart failure (particularly heart failure with reduced ejection fraction/HFREF) is increasing over time, especially in developing nations. Based on the most recent data from Riset Kesehatan Dasar 2020 (RISKESDAS/Baseline Health Research), heart failure has become the highest etiology of mortality for patients with heart disease in Bali. Moreover, in patients with chronic kidney disease that have already undergone hemodialysis, the incidence of heart failure is increasing to more than 80% of the population. The correlation between renal dysfunction and heart failure has been known extensively with the term “Cardiorenal syndrome”. However, there is a paucity of literature regarding the prevention of renal dysfunction in heart failure patients and the control of dyslipidemia risk factors for preventing renal dysfunction. Renal dysfunction is not only a cause of morbidity but also a risk factor for heart failure patients' mortality; therefore, prevention is essential for improving heart failure patients' prognosis. We conduct research to compare the lipid profiles of patients with acute renal dysfunction and those without acute renal dysfunction who have heart failure. Based on the results of the lipid profile, we enrolled 70 consecutive heart failure patients with dyslipidemia or non-dyslipidemia. The incidence of renal failure in the group with dyslipidemia is 84.2%. We found that acute renal dysfunction patients had a statistically significant (p<0.05) increase in dyslipidemia compared to non-renal dysfunction patients, particularly with high LDL levels. The association between statin therapy and a low incidence of acute renal failure in patients with heart failure was statistically significant (p<0.05), according to additional findings from our study.
Variation in the Oxidative Status of Testicular Tissues During Critical Pubertal Age Under Influence of Bisphenol A
Authors: Srivastava Seema , Sharma Manish Kumar , S Sharey
Published: December 2022

Pubertal development of testis requires stringent regulations and precise expansion of germ cells. Reactive oxygen species (ROS) are involved in regulation and proliferation of spermatogonia. Bisphenol A (BPA) is well known for the induction of oxidative stress in testicular tissues leading to major adversities including reduced fertility in male. In the present study, BPA led response of antioxidants was assessed during critical period of pubertal maturation of testis. Four groups of Wistar albino rats were formed containing 15 animals each; Group I-Control, Group II-administered with 5 mg/kg/d BPA, Group III- administered with 25 mg/kg/d BPA and Group IV- administered with 50 mg/kg/d BPA. These groups were further bifurcated into three distinct periods of exposure i.e. 42-63 PND, 42-91 PND and 42-105 PND, containing 5 animals each. Level of CAT, SOD, GSH, GPx, and LPO was analysed. Linear regression for individual antioxidants and Pearson’s correlation between antioxidants were applied for age-wise analysis of variance. Results showed that during first three weeks (i.e. 42-63 PND) of BPA administration were better tolerated, irrespective of doses. Later intervals indicated significant decline (p<0.05) in the activity and level of antioxidants. Relatedness between variables of antioxidants following BPA exposure and control were extremely low (R2<0.1) indicating differential activity. Nonetheless, between antioxidants strong strength of association (r>0.9) was evident. Although initial toleration against BPA’s oxidative insult was evident, it could not be sustained following 91 or 105 PND. Extremely lower activity of antioxidant at later stage suggested potential delay in testicular maturity.
Detection and Classification of Brain Tumor Using Machine Learning Algorithms
Authors: Refaat Fatma M. , Gouda M. M. , Omar Mohamed
Published: December 2022

The brain is the organ that controls the activities of all parts of the body. The tumor is familiar as an irregular outgrowth of tissue. Brain tumors are an abnormal lump of tissue in which cells grow up and redouble uncontrollably. It is categorized into different types based on their nature, origin, growth rate, and stage of progress. Detection of the tumor by traditional methods is time-consuming and does not widen to diagnose a large amount of data and is less accurate. So, the automatic diagnosis of the tumors in the brain by magnetic resonance imaging (MRI) plays a very important role in computer-aided diagnosis. This paper concentrates on the diagnosis of three kinds of brain tumors (a meningioma, a glioma, and a pituitary tumor). Machine learning algorithms: KNN, SVM, and GRNN are suggested to increase accuracy and reduce diagnostic time by using a publicly available dataset, features that are extracted of images, data pre-processing methods, and the principal component analysis (PCA). This paper aims to minimize the training time of the suggested algorithms. The dimensionality reducing technique is applied to the dataset and diagnosis using machine learning algorithms, such as Support Vector Machines (SVM), K-Nearest Neighbor (KNN), and Generalized Regression Neural Networks (GRNN). The accuracies of the algorithms used in diagnosing tumors are 97%, 96.24%, and 94.7% for KNN, SVM, and GRNN, respectively. The KNN is therefore regarded as the algorithm of choice.

Published: January 2023

Aims

Management of displaced paediatric supracondylar elbow fractures remains widely debated and actual practice is unclear. This national trainee collaboration aimed to evaluate surgical and postoperative management of these injuries across the UK.

Methods

This study was led by the South West Orthopaedic Research Division (SWORD) and performed by the Supra Man Collaborative. Displaced paediatric supracondylar elbow fractures undergoing surgery between 1 January 2019 and 31 December 2019 were retrospectively identified and their anonymized data were collected via Research Electronic Data Capture (REDCap).

Results

A total of 972 patients were identified across 41 hospitals. Mean age at injury was 6.3 years (1 to 15), 504 were male (52%), 583 involved the left side (60%), and 538 were Gartland type 3 fractures (55%). Median time from injury to theatre was 16 hours (interquartile range (IQR) 6.6 to 22), 300 patients (31%) underwent surgery on the day of injury, and 91 (9%) underwent surgery between 10:00 pm and 8:00 am. Overall, 910 patients (94%) had Kirschner (K)-wire) fixation and these were left percutaneous in 869 (95%), while 62 patients (6%) had manipulation under anaesthetic (MUA) and casting. Crossed K-wire configuration was used as fixation in 544 cases (59.5%). Overall, 208 of the fixation cases (61%) performed or supervised by a paediatric orthopaedic consultant underwent lateral-only fixation, whereas 153 (27%) of the fixation cases performed or supervised by a non-paediatric orthopaedic consultant used lateral-only fixation. In total, 129 percutaneous wires (16%) were removed in theatre. Of the 341 percutaneous wire fixations performed or supervised by a paediatric orthopaedic consultant, 11 (3%) underwent wire removal in theatre, whereas 118 (22%) of the 528 percutaneous wire fixation cases performed or supervised by a non-paediatric orthopaedic consultant underwent wire removal in theatre. Four MUA patients (6%) and seven K-wire fixation patients (0.8%) required revision surgery within 30 days for displacement.

Conclusion

The treatment of supracondylar elbow fractures in children varies across the UK. Patient cases where a paediatric orthopaedic consultant was involved had an increased tendency for lateral only K-wire fixation and for wire removal in clinic. Low rates of displacement requiring revision surgery were identified in all fixation configurations. Cite this article: Bone Joint J 2023;105-B(1):82–87.

Foreign Body Impaction in the Buccal Mucosa of a Child – A Case Report
Authors: Subalakshmi Krishnamurthy  , Loganayagi Ramalingam  , Karthikeyan Thirugnanasambandam
Published: December 2022

Foreign bodies may be traumatically or iatrogenically embedded in the oral cavity. Traumatic impaction of foreign bodies intraorally in children is common, as they are playful and are unaware of the consequences. A case of traumatic penetration of glass shards in the cheek of a 10-year-old female child which is present for three years, and its management is discussed here and the importance of detailed case history, clinical and radiographic examinations in arriving at the diagnosis and planning the treatment are presented in this article.

Foreign bodies are objects that are not native to the human body, and they may be ingested, inserted into a body cavity, or deposited into the body by traumatic or iatrogenic injury.[1] Traumatic foreign body impaction in oral cavity is mostly due to assaults and motor vehicle accidents[2] or sometimes may be due to blast injury. Foreign bodies generally in oral cavity may be broken instruments, restorative materials, needles etc., or may range from fish bones, coins, stapler pins, small toys, metal pieces which may be quite common in younger age groups.[3]

The foreign bodies once impacted get localized and ensue fibrosis and host response depending on the type of the material impacted. They may cause swelling, abscess formation, septicaemia, or lead to severe haemorrhage; may also undergo distant embolization.[1]

Here we report a case of traumatic penetration of glass shards into the buccal mucosa of a female child due to a blast injury which was there for three years without any major complaints.

Rapid urbanization has become an immense problem in Lahore city, causing various socio-economic and environmental problems. Therefore, it is noteworthy to monitor land use/land cover (LULC) change detection and future LULC patterns in Lahore. The present study focuses on evaluating
the current extent and modeling the future LULC developments in Lahore, Pakistan. Therefore, the semi-automatic classification model has been applied for the classification of Landsat satellite imagery from 2000 to 2020. And the Modules of Land Use Change Evaluation (MOLUSCE) cellular automata
(CA-ANN) model was implemented to simulate future land use trends for the years 2030 and 2040. This study project made use of Landsat, Shuttle Radar Topography Mission Digital Elevation Model, and vector data. The research methodology includes three main steps: (i) semi-automatic land use
classification using Landsat data from 2000 to 2020; (ii) future land use prediction using the CA-ANN (MOLUSCE) model; and (iii) monitoring change detection and interpretation of results. The research findings indicated that there was a rise in urban areas and a decline in vegetation, barren
land, and water bodies for both the past and future projections. The results also revealed that about 27.41% of the urban area has been increased from 2000 to 2020 with a decrease of 42.13% in vegetation, 2.3% in barren land, and 6.51% in water bodies, respectively. The urban area is also
expected to grow by 23.15% between 2020 and 2040, whereas vegetation, barren land, and water bodies will all decline by 28.05%, 1.8%, and 12.31%, respectively. Results can also aid in the long-term, sustainable planning of the city. It was also observed that the majority of the city's urban
area expansion was found to have occurred in the city's eastern and southern regions. This research also suggests that decision-makers and municipal Government should reconsider city expansion strategies. Moreover, the future city master plans of 2050 must emphasize the relevance of rooftop
urban planting and natural resource conservation.
Influência da Incerteza da Política Econômica nos níveis de Accruals e Retornos Anormais
Authors: Santos Wesley Cirino dos , Souza Gustavo Henrique Dias , Coaguila Robert Aldo Iquiapaza , Takamatsu Renata Turola
Published: January 2023

Objetivo: Analisar a relação entre a incerteza da política econômica no mercado acionário brasileiro e a anomalia dos accruals no período de 2010 a 2019.
Método: Foram realizados procedimentos de séries temporais usando o modelo CAPM com a inclusão do fator de accruals, para se obter o retorno anormal do fator analisado. A partir disso, avaliou-se como a incerteza da política econômica afetou o retorno anormal devido aos accruals, calculado por meio da abordagem de dados em painel de efeitos fixos com erros padrão robustos clusterizados.
Resultados e Discussão: Os resultados do estudo sugerem que a incerteza da política econômica influencia os retornos anormais dos accruals, indicando que as ações apresentam menores retornos em períodos de maior incerteza da política econômica. Os resultados são consistentes com o fato de que aumentos na incerteza da política econômica podem induzir investidores a vender ações, reduzindo os preços das ações e, consequentemente, seus retornos. Apesar disso, investidores racionais poderiam colher prêmios de incerteza conforme houvesse recuperação dos preços em momentos seguintes.
Contribuições: A incerteza de política econômica pode ser considerada um tópico importante para a academia e para entidades formuladoras de políticas, bem como a análise dos impactos dos retornos nos mercados de ações. Além disso, o estudo pode auxiliar gestores de portfólio e investidores nos mercados financeiros, a fim de melhorar a estabilidade de implementação de políticas e evitar flutuações anormais nos mercados acionários, além de sugerir estratégias de investimento com perspectivas baseadas na incerteza da política econômica.

O Atlântico Negro de Paul Gilroy é costurado por  dinamismos econômicos e políticos que embarcam as vidas negras em um oscilante processo de pertencimento e não-pertencimento ao local cultural em que desaguam. A demarcação histórica desses movimentos remete, de maneira inadiável, à internacionalização do capitalismo e à sua face equivalente: a designação dos povos não-brancos e não-europeus pelo fator raça. O presente trabalho busca apontar o que se oculta quando não é observada a expansão mundial do Capitalismo em uma relação causal para com a categorização racial dos indivíduos negros. Para tanto, será investigada a díade América e Modernidade em suas formulações correspondentes. Em seguida, será pensada a raça enquanto “instrumento mental” da Modernidade e fator de exploração colonial capitalista. Por fim, serão consideradas as estruturas racistas para além de suas manifestações físicas, combinando elementos investigativos da História e da Psicologia. O esforço metodológico, então, compreende dialogar com a bibliografia rica e relevante dos estudos decoloniais e racializados sobre a colonização e a história colonial dos povos afro-americanos. O trabalho, ciente das suas limitações, conclui que há espaço para esquecimento ao se tratar do esplendor da Modernidade, em função de fazer lugar para a memória da Colonialidade.

El objetivo de esta investigación fue evaluar el sistema agroforestal Milpa Intercalada con Árboles Frutales (MIAF) durante un ciclo productivo (2020-2021) en la comunidad Icalumtic, Municipio de Chamula, Chiapas, comunidad que ha desarrollado una experiencia de diez años con este sistema agroforestal. Se utilizó un método de evaluación de la sustentabilidad agroecológica propuesto por Altieri y Nicholls (2002) usando 30 indicadores cuantitativos y cualitativos, los cuales fueron definidos con la comunidad de manera participativa. Estos indicadores estuvieron categorizados en tres ejes de sustentabilidad: eje ecológico-técnico-productivo, eje socioeconómico y eje sociopolítico-cultural, abordados desde los conceptos de la agricultura sustentable y los sistemas agroforestales. Se aplicó el cuestionario a ocho hombres y ocho mujeres y en cada parcela se hicieron muestreos de área en cuadrados de 5x5m. Los resultados se sistematizaron en hojas excel, para ser analizados con gráficas “ameba”, para lo cual se usó una escala de 0 a 10 para calificar la sustentabilidad del sistema de acuerdo con los indicadores propuestos, 0 para el menos sustentable y 10 para el más sustentable. Para el análisis de los resultados de los muestreos en parcelas y los cuestionarios también se usó estadística descriptiva y análisis del discurso. Entre los resultados se obtuvo un promedio general y mediante el análisis de los gráficos radiales, encontramos un promedio de 8.16 para el eje ecológico técnico productivo, de 7.23 para el eje sociopolítico-cultural, ambos dentro de la sustentabilidad medianamente aceptable; para el eje socioeconómicos fue de 4.04, dentro de la sustentabilidad no aceptable.
Komunikasi Pernikahan Beda Budaya (Studi Komunikasi Antarpribadi Pasangan Arab Alawiyyin dan Non-Alawiyyin di Kampung Arab Solo, Jawa Tengah)
Authors: Menzelthe Caecilia
Published: December 2022

This study aims to find out how the processes, communication barriers, and adaptations carried out by different cultural couples between Arab Alawiyyin and Non-Arab Alawiyyin in their married life. Communication is the main key in a marriage. Especially in a marriage between two people with different cultural backgrounds, interpersonal communication is important to achieve harmony in a family. This research is a phenomenological study that aims to determine the subjective experience of interpersonal communication between Alawiyyin and non-Alawiyyin Arab marriage couples. The results showed that interpersonal communication between Alawiyyin and non-Alawiyyin Arab couples took place harmoniously because of adjustments made before and during the marriage period. Commitments and agreements are made and negotiated with effective communication between the two. Communication barriers in general can be overcome well, even though at the beginning of marriage it was the toughest moment for couples to adjust. Differences in culture, customs, norms and values between partners are other factors that hinder communication. Openness, empathy, mindfulness, cultural sensitivity, and other effective interpersonal communication skills are keys to success in intercultural marriage relationships. In addition, the extended family and its values are the main factors that must be compromised, especially in the early moments of marriage.

Second, when involving the audience when voting to support the contestants through the RCTI+ and MotionPay applications with top-up balances. The two applications were developed by MNC Group as the owner of the media that broadcast The Voice: All-Stars GTV. Apart from being successful in gaining advertisements, the television stations also succeeded in promoting other products in the form of applications developed by the company.
Thomistic Simplicity and Distinguishing the Immanent and Economic Trinities
Authors: Hollingsworth Andrew
Published: December 2022

I argue that there is a discrepancy between the Thomistic doctrine of divine simplicity and affirming the immanent-economic distinctions in the Trinity. Since God is an absolutely simple essence whose essence it is to exist, and since the simple God exists as pure act—lacking all potential—there exist no real distinctions in God, such as physical or metaphysical parts, and there exist no divisions in the life of God, who exists in atemporal eternity. Per the immanent-economic distinctions in the Trinity, the Son is submissive to the will of the Father in the latter but not the former. This appears to be a distinction in the life of the Triune God, which is not acceptable per divine simplicity. After examining the Trinity doctrine and christology of Thomas along with possible solutions to the problem proposed, I conclude that said solutions fail to eliminate the discrepancy between Thomas’s account of simplicity and the immanent-economic distinctions in the life of the Trinity.

Bu araştırmanın amacı; özel eğitim öğretmen adaylarının “özel eğitim öğretmenliği” mesleğine ilişkin metaforik algılarını ortaya çıkarmaktır. Nitel araştırma desenlerinden betimsel tarama modelinde tasarlanan araştırmanın katılımcıları, birinci ve dördüncü sınıf düzeyindeki 134 özel eğitim öğretmen adayıdır. Veriler öğretmen adaylarından, “özel eğitim öğretmenliği ……. gibidir/benzer, çünkü ….….” cümlesini tamamlamaları istenerek toplanmış ve içerik analizi ile çözümlenmiştir. Öğretmen adayları toplam 124 geçerli metafor üretmişlerdir. Üretilen bu metaforlar ortak özellikleri ve benzetme yönleri dikkate alınarak yedi kategori altında toplanmıştır. Kategoriler incelendiğinde en fazla metafor, farklılıkların bir araya geldiği yer (27,41) daha sonra ise emek, özveri ve gayret gerektiren (25,80) kategorilerinde toplanmıştır. Ayrıca öğretmen adayları; farklılıkların bir araya geldiği yer ve sabır abidesi kategorilerinde birbirlerine yakın sayıda, ışık kaynağı/yön gösterici ve şekil veren kategorisinde birinci sınıf, emek, özveri, gayret ve ekip çalışması kategorilerinde ise dördüncü sınıf öğretmen adayları daha fazla metafor üretmişlerdir. Son olarak katılımcıların “özel eğitim öğretmenliğine” ilişkin algılarının olumlu yönde olduğu görülmüştür.

Published: January 2023

Millî Eğitim Bakanlığına bağlı bilim ve sanat merkezlerinde sanat veya genel yetenek alanında özel yetenekli çocuklara yönelik öğretim desteği verilmektedir. Her ne kadar homojen bir grup olduğu varsayılsa da her okulda karşılaşıldığı gibi bilim ve sanat merkezlerinde de farklı özel gereksinimlere sahip öğrenciler bulunmaktadır. Bu öğrenciler özel yeteneğine ek olarak sahip oldukları farklılıklar nedeniyle “iki kere farklı” olarak adlandırılmaktadır. Özel yetenekli öğrencilerin bu farklılıklarının öğretmenler tarafından bilinmesi ve buna göre öğrenme-öğretme sürecini tasarlaması bu öğrencilerin daha iyi kazanımlar elde etmesi için önemlidir. Bu araştırmanın odak noktasını ise her 25 çocuktan birinde görülmekte olan dikkat eksikliği ve hiperaktivite bozukluğu oluşturmaktadır. Bu bağlamda araştırmanın amacı iki kere farklı öğrencilere yönelik bilim ve sanat merkezi öğretmenlerinin düşünce ve yaklaşımlarını ortaya koymaktır. Araştırmanın çalışma grubunu bir bilim ve sanat merkezinde görev yapmakta olan farklı branşlardan 20 öğretmen oluşturmaktadır. Nitel araştırma yöntemlerinden temel nitel araştırmanın kullanıldığı bu araştırmada veriler yarı yapılandırılmış görüşme formu aracılığıyla toplanmıştır. Veriler nitel veri tekniklerinden betimsel ve içerik analizi kullanılarak çözümlenmiştir. Araştırma sonucunda öğretmenlerin iki kere farklı öğrencilere ilişkin yeterli bilgiye ve uygulama yaklaşımına sahip olmadıkları sonucuna ulaşılmıştır.

Published: December 2022

Production scheduling, which directly influences the completion time and throughput of workshops, has received extensive research. However, due to the high cost of real-world production verification, most literature did not verify the optimized scheduling scheme in real-world workshops. This paper studied the verification of scheduling schemes and environments, using a discrete event simulation (DES) platform. The aim of this study is to provide an efficient way to verify the correctness of scheduling environments established by programming languages and scheduling results obtained by intelligent algorithms. The system architecture of scheduling verification based on DES is established. The modelling approach via DES is proposed by designing parametric workshop generation, flexible production control, and real-time data processing. The popular distributed permutation flowshop scheduling problem is selected as a case study, where the optimal scheduling scheme obtained by a deep reinforcement learning algorithm is fed into the production simulation model in Plant Simulation software. The experiment results show that the proposed scheduling verification approach can validate the scheduling scheme and environment effectively. The utilization and Gantt charts clearly show the performance of scheduling schemes. This work can help to verify the scheduling schemes and programmed scheduling environment efficiently without costly real-world validation.

With the gradual normalization of the COVID-19, unmanned delivery has gradually become an important contactless distribution method around China. In this paper, we study the routing problem of unmanned vehicles considering path flexibility and the number of traffic lights in the road network to reduce the complexity of road conditions faced by unmanned vehicles as much as possible. We use Monte Carlo Tree Search algorithm to improve the Genetic Algorithm to solve this problem, first use Monte Carlo Tree Search Algorithm to compute the time-saving path between two nodes among multiple feasible paths and then transfer the paths results to Genetic Algorithm to obtain the final sequence of the unmanned vehicles fleet. And the hybrid algorithm was tested on the actual road network data around four hospitals in Beijing. The results showed that compared with normal vehicle routing problem, considering path flexibility can save the delivery time, the more complex the road network composition, the better results could be obtained by the algorithm.

Logistics is an important guarantee for economic and social development. Among the various aspects of logistics, the urban logistics end distribution link, which involves the direct connection between distribution personnel and customers, has a direct impact on customers' sense of experience and satisfaction with logistics services. At present, there are unscientific and unreasonable selection methods for logistics end distribution paths, often based on the subjective experience of distribution personnel, which often results in a mismatch between distribution paths and distribution needs, affecting market demand while further increasing the distribution costs of enterprises. Therefore, based on the characteristics of customer-consumers, this paper considers that consumers can select multiple receiving addresses, and each address has a corresponding time window limit. This paper finds that it needs to spend a lot of costs for the enterprise to improve the service level of distribution, and the enterprise can save the cost from time window, as well as obtain the better distribution time by using alternative addresses through the verification and analysis of an example. Based on the above analysis, this paper proposes the urban logistics terminal distribution path optimization path based on large-scale neighbourhood search algorithm, which can promote the further matching between logistics distribution enterprises and customer needs, so as to improve the probability of consumers receiving goods in time as well as reduce the cost of enterprises.
