In this paper, we present a novel numerical scheme for a model involving novel mathematical concepts of significant importance for interpreting and examining real-world problems. This paper presents a numerical method for chaotic problems. Using differential and integral operators in the sense of Caputo-Fabrizio, we investigated the chaotic system of mathematical equations able to capture chaotic behaviour. Solutions are obtained for the fractional-order chaotic model using a fractional operator with a non-singular kernel. Uniqueness and boundedness for solution are proved through fixed point theory. Finally, we applied a numerical power series method to solve the proposed fractional model. Due to the high non-linearity of our problem, we used a suitable numerical scheme to solve this system of equations numerically.

This theoretical research explores the potential of applying the learning organisation metaphor within the context of a local municipality to enhance service delivery to its communities. The study examines the implications of embracing Senge's disciplines, namely personal mastery, mental models, shared vision, team learning, and systems thinking, for driving a transformation toward a learning organisation. It establishes how the concept of a learning organisation can be understood and applied to facilitate individual, team, and organisational learning within the municipality. By investigating various case studies and examining literature from various authorities, this article also aims to stimulate dialogue among practitioners and scholars on the efficacy of adopting a learning organisation approach within the municipal context, therefore, the grounded theory method was followed to attain the aim. Findings highlight the potential of the learning organisation metaphor as a catalyst for improving service delivery and enhancing community engagement. The limitation of the current study is its focus on a literature review and the study of one local municipality. It is suggested that its implementation warrants further research and practice in the realm of local governance; and that further study could include three or more municipalities located in various provinces within South Africa, using either qualitative, quantitative research methods or the mixed methods approach.

We presents four patients with respiratory symptoms and radiological finding but without pulmonary diagnosis at the end. The first case is mitral chordae rupture, which is understood as a COPD exacerbation due to the dyspnea and fatigue. Considering normal auscultation finding, not smoker, the overall finding did not indicate COPD. Urgent heart ultrasound gave right diagnosis. The second was admitted as bilateral pneumonia. CT scan showed that it was a large intestinal hernia. The third case was presented as pleural effusion after the onset of acute chest pain. Profile radiography and CT scan diagnosed aortic aneurysm dissection and the patient underwent emergency surgery. The fourth patient underwent chest X-ray as part of the preoperative preparation of gallbladder calculosis, where a nodular tumor shadow was seen. CT scan showed that was a pericardial cyst. Imaging findings must be correlated with clinical manifestations. This paper presents some of the faces of non-pulmonary diseases with respiratory manifestations that can lead us a misdiagnosis and sometimes lethal outcome. A multidisciplinary approach, more diagnostic procedures with an adequate history of illness will give us the right diagnosis. In this way, the patient will receive appropriate treatment

Backgroud. About 50 percent woman had psychiatry symptom before pregnant. They had consumed drug for the rest life. The drug was valproic acid. Consumtion this drug during pregnancy would made neurodevelopmental disorder like Autism Spectrum Disorder (ASD). Brain Derived Neurothropic Factor (BDNF) have a role in development of Nervous system dams. The serum level increase during pregnancy and exercise Valproid acid which is consumed in pregnant may cause the decrease of BDNF level. Aims. Our study aims to investigate serum level of pregnant mice exposed to valproic acid and to investigate relationship level of BDNF with two condition exercise or not in short time. It is important to study to know, if BDNF level of mother is the better marker risk factor born child with ASD. Method. Pregnant mice differed into 4 group (control/1, control with exercise/ 2, valproid acid / 3, valproid acid with exercise /4). Valproic acid 500 mg/weight single dose was given at 16 days pregnant continue exercise for 4 days. Serum BDNF mother was examined. Result. Statistically, All groups had no significant value (p>0,05). But mean of both valproid acid groups, relatively decreased than control group. Exercise did not change the level.Conclusion. It could be concluded that consumtion of valproic acid could changed physiology of secretion of BDNF during prenatal, this is may be the causa of neurodevelopmental Disorder.

The digitalization era is being sparked by Industry 4.0. Manufacturing companies are increasingly implementing Industry 4.0 as a way to boost customized productivity since they provide a number of benefits over conventional manufacturing systems. To keep up with the present level of market rivalry, manufacturing firms are quickly switching from mass production to customized production. The development of customized goods as well as increased operational flexibility, efficiency, and productivity are all made possible by the new technology available to manufacturing industries. The concern of why and how Industry 4.0 is needed for the new market is raised in this situation. So, a survey became required to learn more about the empirical investigations related to the term "Industry 4.0". This review paper covers the empirical investigation that has been carried out on Industry 4.0 implementation with the goal of better understanding these processes, by emphasizing the potential for future research.

The main objective of the study is to analyze the efficiency of resource use levels in corn production using the Data Envelopment Analysis method in Almaty region, Kazakhstan. In the course of the study, data were collected from 96 farmers growing corn in the Almaty region by proportional sampling using a face-to-face survey. According to the research results: the average of maize production area in the farms is 112.63 ha. It was determined that the average maize production amount was 961192.91 kg, and the maize yield per hectare was 8534.07 kg. The average corn price received by the farmers is 0,080 $/kg. Average maize production cost per hectare was calculated as 222,18 $. Average net profit per hectare from maize production has been determined as 462,64 $. It has been determined that the most important criterion for the farmers in selecting and using inputs is the input price. According to the efficiency analysis results, the average efficiency of 96 maize farmers was calculated as 0.74 under the assumption of constant return to scale and 0.95 under the assumption of variable return to scale. A data coverage method was used to analyze the efficiency of the use of inputs in corn production. In Data Envelopment Analysis, data were analyzed according to the CRS (Constant Return to Scale) and VRS (Variable Return to Scale) models, and estimates were made according to both models in the analysis. According to both model assumptions, efficiency results for the input were obtained. In an input-driven model approach, target results can be achieved with minimal use of input resources. It was determined that the most important criterion for farmers in the selection and use of inputs is the cost of inputs. According to the results of the efficiency analysis, the average efficiency of 96 corn farmers was calculated as 0.74 assuming constant returns to scale and 0.95 assuming variable returns to scale.
本研究的主要目的是利用数据包络分析法分析哈萨克斯坦阿拉木图地区玉米生产中资源利用水平的效率。在研究过程中，通过面对面调查的比例抽样，从阿拉木图地区96名种植玉米的农民中收集数据。研究结果表明:各农场玉米生产面积平均为112.63 ha。测定玉米平均产量为961192.91 kg，每公顷玉米产量为8534.07 kg。农民收到的平均玉米价格为0.080美元/公斤。每公顷玉米的平均生产成本计算为222.18美元。每公顷玉米生产的平均净利润已确定为462,64美元。研究表明，农民选择和使用投入品的最重要标准是投入品价格。根据效率分析结果，计算出96个玉米农户在规模报酬不变假设下的平均效率为0.74，在规模报酬变假设下的平均效率为0.95。采用数据覆盖法对玉米生产投入品的利用效率进行了分析。在数据包络分析中，数据分析采用CRS (Constant Return to Scale)和VRS (Variable Return to Scale)模型，并在分析中分别采用这两种模型进行估计。根据两种模型的假设，得到了输入效率的结果。在输入驱动模型方法中，可以用最少的输入资源实现目标结果。经确定，农民选择和使用投入物的最重要标准是投入物的成本。根据效率分析结果，96个玉米农户的平均效率在规模收益不变的情况下为0.74，在规模收益可变的情况下为0.95。

The main purpose of this research is to determine the benefits and satisfaction levels enabled by the agricultural aids for dairy cattle farms that are members of S.S. Çavuşlu Village Agricultural Development Cooperative in the Derince district of Kocaeli province and to provide policy proposals for ensuring the sustainability of farms. For this purpose, the data collected from 61 dairy farmers, who are members of the S.S. Çavuşlu Village Agricultural Development Cooperative, through the face-to-face questionnaire method were analyzed. The dairy farms' activities in 2020 were analyzed under three groups based on the number of dairy cows. Farms with 5 or fewer dairy cows were designated as Group I (19 farms), farms with 6-10 dairy cows as Group II (21 farms), and farms with 11 and more dairy animals as Group III (21 farms). While evaluating the data, simple average and percentage calculations were performed. The Five-Point Likert Scale was used to evaluate the farmers’ opinions, expectations, and satisfaction levels regarding livestock support programs in the farms examined. The research employed the fuzzy pairwise comparison method to determine the support preferences of farmers in dairy cattle breeding. According to the results of the research, the average farm age was determined as 52.41 years, the average education level was 6.60 years, and the agricultural experience was 38.46 years. The average farmland size was 151.41 decares. The average number of dairy cows on the farms was 8.64. The average daily milk yield per animal was 12.68 kg. The average milk selling price was 0.37 USD/kg. According to the Fuzzy Pairwise Comparison, six different support tools were provided to farmers, and they chose milk and forage crop aids as priority support tools. High production costs, especially high feed prices, the inability to sell milk at an affordable price, and lack of support were the most significant problems identified in the farms. As a result, support policies for dairy cattle should be reviewed, payments should be made earlier, the amount of support provided should be increased, and farmers should be made aware of the organization.

Çavuşlu Village Agricultural Development Cooperative in the Derince district of Kocaeli province and to provide policy proposals for ensuring the sustainability of farms. For this purpose, the data collected from 61 dairy farmers, who are members of the S.S. Çavuşlu Village Agricultural Development Cooperative, through the face-to-face questionnaire method were analyzed. The dairy farms' activities in 2020 were analyzed under three groups based on the number of dairy cows. Farms with 5 or fewer dairy cows were designated as Group I (19 farms), farms with 6-10 dairy cows as Group II (21 farms), and farms with 11 and more dairy animals as Group III (21 farms).
