Design Solution On Keramzit Production and Justification On Its Breakeven Points

Roza Narmanova — 2025-06-01

The article considers the issues of determining the effectiveness of a design solution for organizing the production of keramzit based on low-intumescent loams, barchan sands and oil sludge using plastic processing and molding. By calculations it is proven that the use of substandard natural raw materials and industrial waste makes it possible to reduce the market value of keramzit. The justification for the efficiency of organizing the production of new products was carried out considering the costs of keramzit production and drawing up a break-even format for the design solution in accordance with certain formulas and accepted models for determining the economic efficiency of production options (existing and proposed technology). The economic effect was obtained from the use of new technology with an increasing amount of revenue and profitability, and there was also a reduction in the payback period of capital investments, allowing us to conclude that it is advisable to introduce the developed technology for the production of keramzit.

Challenges Facing Employee Training and Development: A Case of Kazakhstan Service Sector

Narmanova Medina — 2025-07-13

The goal of this research is to investigate the issues encountered in staff training and development within the Kazakhstani service industry, pinpointing significant barriers and suggesting viable alternatives to improve worker competencies. A qualitative study technique was employed, which included semi-structured interviews with human resource managers and training specialists from a variety of service sectors in Kazakhstan. Secondary data, including academic literature and industry reports, were examined to contextualize the findings. Furthermore, the internal consistency of the questionnaire was evaluated using statistical tools such as Cronbach's alpha, and the adequacy of the sample for factor analysis was assessed using the Kaiser-Meyer-Olkin (KMO) measure and Bartlett's test of sphericity. The research revealed numerous critical challenges: a discrepancy between educational curricula and industry requirements resulting in skill deficiencies; dependence on antiquated training methodologies; restricted access to quality training due to geographical and financial barriers; language and cultural diversity hindering standardized training; technological obstacles such as a digital divide and swift technological advancements; resistance to change from personnel and management; regulatory and compliance complications; elevated employee turnover; a scarcity of qualified trainers; and financial constraints impacting training investments. The study's shortcomings stem from its qualitative emphasis and the particular environment of Kazakhstan's service industry, potentially impacting the generalizability of the findings. Future investigations may include quantitative analysis and expanded geographic scope. This study enhances the sparse literature on human resource development problems in developing nations by providing insights pertinent to Kazakhstan's service industry. The results may guide politicians, educators, and business leaders in formulating specific solutions to address these difficulties.

BIM and Primavera Integration in Structural Project Planning: A Simulation Based Study

Noor Jameel Mohammed — 2025-08-22

The integration of structural design and construction scheduling has become increasingly important in enhancing the efficiency and success of civil engineering projects. Traditionally, these two phases have been treated separately, often leading to miscommunication, delays, and cost overruns. With the development of digital tools such as Building Information Modeling (BIM) and project scheduling software like Primavera P6, there is a growing opportunity to bridge this gap through integrated workflows. This study aims to explore how modern digital tools can improve coordination between design and execution stages in civil engineering projects. Specifically, it investigates the impact of integrating BIM with construction scheduling on time management, resource utilization, and interdisciplinary coordination through a simulated practical approach. A five-story residential building was modeled using BIM software (Revit), and its construction schedule was developed using Primavera P6. These tools were integrated to create a 4D BIM model that visualizes the construction sequence and enables early detection of potential conflicts before actual implementation. The findings demonstrated that the integrated approach significantly improved project performance. It reduced the total project duration by up to 13.5%, decreased the number of design changes from 14 to only 5, and increased resource utilization efficiency from 78% to 92%. Clash detection identified 48 conflicts prior to execution, highlighting the benefits of early-stage coordination. This research concludes that integrating structural design with construction scheduling using BIM and scheduling tools enhances time management, cost control, and collaboration across disciplines. It also emphasizes the need for training and investment in digital technologies to support broader adoption in the construction industry.
