This study presents a systematic optimization methodology for minimizing lateral displacement in reinforced concrete (RC) high-rise buildings subjected to combined wind and seismic loading. Grounded in Smith–Coull frame–wall interaction theory and validated through three-dimensional finite element analysis (ETABS 2022), the procedure was applied to a representative 20-story RC structure (H = 72 m) in Thai Nguyen, Vietnam, designed per TCVN 2737-2023 and TCVN 9386:2012. A two-stage optimization strategy was developed: (i) maximizing the non-dimensional stiffness parameter.......

Keywords: RC high-rise buildings; frame–shear wall system; lateral displacement; stiffness optimization; ETABS; TCVN 2737-2023.

This paper proposes an integrated Building Information Modeling (BIM) and Data Mining model to improve the efficiency of high-rise building construction management.The model was implemented in practice on a 25-story high-rise apartment building with a total floor area of 32,000 m² in Thai Nguyen City, during a construction period of 24 months (January 2024 – December 2025).The actual construction data includes daily labor logs (a total of 1,642 workers-days during the floor slab concrete pouring phase), material costs for each structural item (total material value of VND 70.6 billion), actual progress compared to the EVM.......

This paper presents a comprehensive engineering philosophy for the design of flanged nozzle connections between pressure vessels and piping systems, focusing on the interaction between structural integrity, piping flexibility, thermal loading, and gasket sealing performance. Flanged nozzle interfaces are treated not as simple static pressure-retaining joints, but as deformation-sensitive systems whose reliability is governed by the combined effects of internal pressure, external piping loads, thermal expansion and contraction, bolt preload, and flange rotation........

Keywords: Flanged nozzle connections; pressure vessels; piping systems; piping flexibility; thermal expansion; thermal contraction; flange rotation; gasket sealing performance; nozzle loads; bolt preload; leakage prevention; pressure vessel design; piping stress analysis; structural integrity; flange joint reliability.

Bacillus thuringiensis (Bt) has emerged as a promising biological control agent for sustainable pest management in agriculture. This review examines the current understanding of Bt's potential as a biopesticide from both international and national perspectives. The mechanism of action involves the production of crystalline toxins (δ-endotoxins and Cry proteins) that disrupt the intestinal epithelium of susceptible insect larvae, leading to their mortality while remaining.......

This study evaluates the success of the Self-Help Housing Stimulant Assistance (BSPS) Program in Tolitoli Regency by analyzing the impact of planning quality and field supervision on beneficiary satisfaction. Using an explanatory quantitative approach, data were collected from 240 program beneficiaries (2023–2024) via purposive sampling and analyzed using Partial Least Squares-Structural Equation Modeling (PLS-SEM). The results show that planning quality and field supervision have a positive and significant effect, both partially and simultaneously, on beneficiary satisfaction........

Keywords: Satisfaction, Planning Quality, Field Supervision, Stimulus Assistance, PLS-SEM.

This study provides a comprehensive geological characterization and evaluates the slope stability in Segment 5 of the Kalawara-Kulawi Road, a highly earthquake-prone zone in Central Sulawesi. Field investigations and laboratory analyses, including Petrography, X-Ray Fluorescence (XRF), and kinematic analysis, were conducted to assess the rock mass quality. The computational stability analysis was performed using the Limit Equilibrium Method (LEM) with the Morgenstern.......

Keywords: Slope Stability, Limit Equilibrium Method, Factor of Safety, Seismic Load, Pseudostatic.

Karl Raimund Popper was one of the major philosophers of science of the twentieth century. Although Popperian philosophy did not develop into a closed school of thought, his contributions have been widely welcomed and acknowledged. Among his notable contributions is social liberalism, the political standpoint from which he criticized historicism and the enemies of the open society. Therefore, to understand Popper's view of the open society and historicism, it is necessary to examine the substance and defining features of his social liberalism. This article analyzes the basic elements of Popper's social-liberal position and, on that basis, identifies several of his philosophical contributions.

Keywords: Philosophy of science; social liberalism; open society; historicism.
