In the domain of Industrial Internet of Things (IIoT), the demand for robust and secure methods for goods tracking and management has become growingly critical. Conventional methods face significant challenges, including authentication, computational overhead, cyber security, and data integrity. To address these issues, this paper proposes a block-chain based system for goods management and tracking with enhanced authentication mechanism by leveraging the decentralized nature of block-chain technology and integrating Elliptic Curve Digital Signature Algorithm (ECDSA) with Elliptic Curve Cryptography-Zero Knowledge Proof (ECC-ZKP). The proposed solution aims to ensure the authenticity and the integrity for all the transaction while providing high level privacy-preserving verification without revealing information. The research in this paper demonstrates that the proposed block-chain-based system significantly enhances security performance, key management and operational efficiency, addressing the existing challenges in IIoT goods tracking and management, providing a resilient framework for more secure industrial operations in managing goods.

CELIAC DISEASE: NEW POSSIBILITIES FOR DIAGNOSIS AND MANAGEMENT

Вackground. Celiac disease is an autoimmune disease that occurs in genetically predisposed individuals and is characterized by damage to the mucous membrane of the small intestine due to exposure to gluten. The interest of researchers in gluten-associated diseases is growing every year. The true prevalence of celiac disease is not sufficiently studied due to the rarity of "classic" cases and the higher frequency of atypical and various clinical manifestations of this disease. Manifestation of celiac disease is possible at any age, the disease is more often diagnosed in adults. All this dictates the need to develop new algorithms for examining patients for timely detection and treatment of сеliacia. Aim: To review updated key consensus documents on the diagnosis and treatment of celiac disease. Matherials and methods. The results of scientific research related to celiac disease were searched. The studies that are included were selected based on searches in the online databases PubMed, Web of Science, Scopus, Google Scholar and others and relate to the basic methods of diagnosis and management of celiac disease. 110 sources were selected for analysis, of which were used that met the search criteria. Results. Based on the analysis of experimental and clinical studies, difficulties were identified in diagnosing celiac disease associated with a greater prevalence of extraintestinal manifestations and a rarity of "classical" cases. Methods of approach to the diagnosis of celiac disease in children and adults have been developed, taking into account invasiveness and accessibility. The basic approach in the treatment of celiac disease is a observed gluten-free diet. Regarding the selection of products, the individual characteristics of each patient are taken into account. Conclusion. To verify the diagnosis, adults and children with suspected celiac disease are recommended to perform esophagogastroduodenoscopy with biopsy of the duodenal mucosa at several points. An alternative method of diagnosis can be a combination of a very high level of antibodies of the imonoglobulin (Ig) A class to tissue transglutaminase (TGAs) and positive antibodies to endomysium (anti EMA) in two blood samples, however, no single analysis is 100% specific for celiac disease, and the diagnostic accuracy varies significantly between different laboratories. The only proven effective treatment for celiac disease is a lifelong gluten-free diet. In the absence of a complete clinical and serological response to diet, treatment goals are determined individually for each patient. The development of new treatments for celiac disease continues.

HRD Conducts Research Using Public Sector Banks and Private Sector Banks

The banking sector, which is reliant on the health of the public, was discussed in this article. Only people use its services, and they are also the only ones who directly influence productivity. Up until 1969, banking was still in some ways a traditional enterprise. when the Indian government took over major banks. Banks became a powerful force for social change after being nationalized and ceased to be the sole source of finance for industry. The assertion that the banking industry is increasing astronomically is supported by additional proof in the form of statistics. The Indian banking industry needs to be governed by banking professionals if it is to profit from the sector on a global scale. The goal of the study is to look at four important factors that have a big impact on how the banking industry develops in private sector banks: selection and recruitment policies, training, performance appraisal, and compensation. For this descriptive and exploratory analysis, the researcher used a standard random sampling technique. In the study, employee impressions of the HRD environment in the two largest banks are assessed. Additionally, it looks to examine if bank employees working for public and private sector banks have different perspectives on each facet of the HRD climate. The HRD climate is divided into three categories: General Climate, OCTAPACE, and HRD Mechanisms. 200 employees submitted the primary data using a standardized questionnaire with 40 items. KEY WORDS Performance review, bank employees, private banks, and methods of human resource management.

Overview of the Impact of Compost on Bulk Density, Aggregate Consistency and Cation Exchange Capacity of Soils and its Consequential Effect on Crop Productivity

Organic fertilizers offer several advantages over chemical fertilizers and are an environmentally friendly alternative that could help sustainably farmed land. Reviewing indigenous knowledge of the agronomic applications of organic manure and its possible contribution to agricultural growth was the goal of this article. It is evident that organic manures from various plant and animal sources can be used to satisfy certain field needs. However, the use of organic manures is still primarily conventional since they have not been well received by agricultural strategies. When bulky organic manures are directly applied to soil, they accelerate mineralization and reduce the rate at which nutrients, especially nitrogen, are released. Compared to raw resources, which have limited value and certain disadvantages, composting these wastes appears to offer significant potential. The majority of researchers verified that adding compost might enhance the soil's organic matter content, nutrient status, and physical, chemical, and biological properties. Soil organic matter concentrations rise in every long-term compost treatment study. But since they contain more stable carbon than fresh or immature composts, mature composts raise Soil organic matter considerably more effectively. Furthermore, because compost has so many beneficial effects on the physical, chemical, and biological aspects of soil, it helps to stabilize and improve crop quality and yield. As a result, the majority of studies have demonstrated that compost has an equalizing influence on seasonal and annual variations in soil temperature, air, water, and plant nutrient availability, as well as crop yields. mostly due to the nutrients' gradual release and availability in compost-combined fertilization techniques, which frequently yield positive outcomes. Therefore, composting can be a useful choice for building effective plant-nutrient management methods in many settings for sustainable agricultural systems within small-scale farming in impoverished nations.

Sheath Blight and Bacterial Blight Resistance in Rice: Mechanisms, Progress and Future Perspectives for Sustainable Rice Production

Rice (Oryza sativa L.) is a staple food for nearly half of the world's population, including Pakistan. But several diseases are always posing a threat to rice farming, with bacterial blight and sheath blight being the two most common causes. R. solani is the main source of rice sheath blight and stood crop’s most destructive diseases. Reviewing published data on pathogenicity and disease management is crucial to developing effective crop protection against sheath blight. It also helps identify research gaps that need more in-depth investigation. Although there has been progress in identifying rice and pathogen-related genes linked to pathogenesis, the underlying processes are still unknown. Research on the applications of; agronomic techniques, chemical control, biological control, and genetic improvement in disease management strategies has been conducted. Optimizing the application of nitrogen fertilizer in combination to plant-plant spacing can minimize the transmission of infection, whereas SMART agricultural technologies; like crop monitoring using Unmanned Aerial Systems help detect and treat sheath blight disease early on. Biological agents and natural fungicides can be used to effectively prevent sheath blight while reducing the negative effects on the environment. Genetic strategies that hold potential to control sheath blight include the use of exogenous dsRNA to suppress pathogen gene expression, genome editing to create rice lines less susceptible to sheath blight, and the development of transgenic rice lines that over express or silence genes related to pathogenesis. The pathogen’s flexibility, the absence of resistant rice types, the lack of single resistance genes for breeding, and farmers' restricted access to informative programs about optimum management methods all work against effective crop protection against sheath blight.

Improving the overall equipment effectiveness of Sheet-Fed offset printers: A case study

This study investigates a framework for enhancing the Overall Equipment Effectiveness (OEE) of sheet-fed offset printers, focusing on the packaging sector. The research explores the understanding and implementation of OEE valuation within this context. Through a specific case study, the OEE value is 22%, with contributions from Availability, Performance, and Quality rates at 41%, 58%, and 94%, respectively. These findings underscore a substantial deviation from the world-class standard of 85%, indicating significant room for improvement. Based on Six Big Losses (SBL) and Cause and Defect diagram analysis, workers' lack of knowledge and skill and ineffective management methods are critical contributors to low OEE rates. In response, an action plan is proposed to improve OEE, aiming to reduce time losses by approximately 60% and achieve a standard OEE value. This research offers valuable insights into optimizing the efficiency of sheet-fed offset printers, offering practical strategies for enhancing productivity and competitiveness in the printing industry.

A Multi-Objective Evaluation Method for Smart Highway Operation and Management

Smart highways represent a novel highway concept in the era of big data, emphasizing the synergy among people, vehicles, road facilities, and the environment. However, the operation and management of smart highways have become more intricate, surpassing the adaptability of traditional highway evaluation and management methods. This study integrates the distinctive characteristics of smart highway facilities and operational objectives to enhance and modernize the existing highway evaluation system. Drawing from research on smart highway construction projects, a smart highway evaluation system encompassing facility structure, electromechanical facilities, and operation services is formulated based on a hierarchical analysis method. The quantitative evaluation of each indicator is achieved by combining existing specifications and expert questionnaire solicitation. The group decision-making method is initially employed to optimize subjective weights, followed by the calculation of combined weights using both the entropy weight method and critic method in objective evaluation. Finally, a comprehensive evaluation model is established and validated through engineering projects. The results demonstrate that the evaluation system effectively highlights the advantages and disadvantages in the operation and management of smart highways, thereby fostering the advancement of smart highway iteration.

BUILDING SHOWCASE PLATFORM

Abstract : Formal project management is not widespread in SMEs. Most of the office work and normal business activities are looked by the staff in an informal manner and in most cases without any project management training. This is not to say that their projects are not successful. Many SMEs handle projects well and are successful. This could be due to their tactical knowledge and the individuals involved rather than a conscious effort. But these companies could be falling short of their potential and may perform better if they follow a proper formal system of project management practices. Management, produces a degree of predictability, focuses on systems, relays on control, organizes and staffs, accepts the status quo and motivates people to comply with standards. This project aims to study the approach of small and informal construction firms towards construction management and the various techniques adopted by them and thereby suggest systems and methods in project management to improve their performance. A startup construction firm that did not have formal project management systems and techniques in place was identified and upon discussion with their owners and employees regarding their practices, they were willing to let us assist them in their projects by setting up a project management function there by analyzing their work. During the course of the study, significant improvements were observed in the system adopted by the firm in various aspects like quality control, project monitoring & tracking and safety. It can thus be concluded that introduction of project management techniques even though on a small but systematic way can help bring improvement in the performance of the firm and contribute to the organization’s growth in the long run.

Mapping Stakeholders in the Development of Eco-Cities: Insights from Nepal and Indonesia

Urban areas are dynamic and intricate, encompassing various social, economic, ecological, and cultural aspects. It's crucial to employ effective approaches and management methods to achieve sustainable urban development. Stakeholder analysis is pivotal in understanding their roles and responsibilities in this process. By analyzing potential stakeholders and their responsibilities, enhances achieving development goals. This paper uses ‘solid waste bank’ and ‘socio-cultural water management approach’ case of Surabaya, Indonesia and Lalitpur, Nepal respectively. The challenges stakeholders face when implementing have been studied and mapped. Additionally, the significance of stakeholders in implementing development plans and policies has been reviewed through relevant journals and reports, considering the current cases of solid waste management and water management only. The mapping of stakeholders’ problems and prospects revealed that none of the stakeholders had low influence and low importance in both Nepal and Indonesia. This finding suggests that further studies could explore other relevant aspects of the stakeholder dynamics that could contribute to developing eco-city in both the countries. Also mapping, synthesizing both situation and stakeholder of other practices, and upgrading the practices as well may help achieve eco-city, which is unique, inclusive and has the contextual flavors.

Avian Orthoreoviruses: A Systematic Review of Their Distribution, Dissemination Patterns, and Genotypic Clustering.

Avian orthoreviruses have become a global challenge to the poultry industry, causing significant economic impacts on commercial poultry. Avian reoviruses (ARVs) are resistant to heat, proteolytic enzymes, a wide range of pH values, and disinfectants, so keeping chicken farms free of ARV infections is difficult. This review focuses on the global prevalence of ARVs and associated clinical signs and symptoms. The most common signs and symptoms include tenosynovitis/arthritis, malabsorption syndrome, runting-stunting syndrome, and respiratory diseases. Moreover, this review also focused on the characterization of ARVs in genotypic clusters (I-VI) and their relation to tissue tropism or viral distribution. The prevailing strains of ARV in Africa belong to all genotypic clusters (GCs) except for GC VI, whereas all GCs are present in Asia and the Americas. In addition, all ARV strains are associated with or belong to GC I-VI in Europe. Moreover, in Oceania, only GC V and VI are prevalent. This review also showed that, regardless of the genotypic cluster, tenosynovitis/arthritis was the predominant clinical manifestation, indicating its universal occurrence across all clusters. Globally, most avian reovirus infections can be prevented by vaccination against four major strains: S1133, 1733, 2408, and 2177. Nevertheless, these vaccines may not a provide sufficient defense against field isolates. Due to the increase in the number of ARV variants, classical vaccine approaches are being developed depending on the degree of antigenic similarity between the vaccine and field strains, which determines how successful the vaccination will be. Moreover, there is a need to look more closely at the antigenic and pathogenic properties of reported ARV strains. The information acquired will aid in the selection of more effective vaccine strains in combination with biosecurity and farm management methods to prevent ARV infections.

Development of a method for managing technical systems using a bio-inspired algorithm

Today’s management solutions depend precisely on the successful solution of optimization problems, which are discontinuous, undifferentiated and multimodal. One of the approaches to increase the efficiency of solving optimization problems is bio-inspired algorithms. The object of the study is complex dynamic objects. The subject of the study is the decision-making process in the problems of managing complex dynamic objects. A management method using a bio-inspired algorithm is proposed. The research is based on the goose algorithm – for finding a solution to the state of dynamic objects with a hierarchical structure. Evolving artificial neural networks are used to train goose agents (GA) and an advanced genetic algorithm is used to select the best ones in the combined swarm algorithm. The originality of the proposed method lies in setting GA taking into account the uncertainty of the initial data, improved global and local search procedures. Also, the originality of the study lies in determining GA food locations, which allows choosing the priority of search in a given direction. The next element in the originality of the study is the ability to determine the indicators of guard GA, which allows adjusting the amount of time during which the GA flock will be located. Another original element of the study is the determination of the initial velocity of each GA. This makes it possible to optimize the speed of conducting exploration by each GA in a certain research direction. The method allows increasing the efficiency of data processing at the level of 10–12 % by using additional improved procedures. The proposed method should be used to solve problems of evaluating complex dynamic objects
