Abstract

Architectural engineering in the digital era is increasingly shaped by parametric design methodologies that enable complex form generation and performance-driven optimization. Rapid advancements in computational tools have transformed design processes, yet a persistent gap remains between architectural exploration and structural rationalization, often resulting in inefficiencies and post-design adjustments. This study aims to develop an integrated computational framework that aligns parametric design with structural performance, ensuring that architectural forms are both innovative and structurally feasible. A computational design-based methodology was employed, combining parametric modeling, finite element analysis, and algorithmic optimization across representative architectural typologies. Iterative workflows were implemented to establish continuous feedback between geometric parameters and structural responses. Results indicate that integrated parametric-structural models achieve higher structural efficiency, reduced material consumption, and improved deformation control compared to conventional and non-integrated approaches. Statistical analysis confirms significant performance improvements, while case-based validation demonstrates strong alignment between simulated and expected structural behavior. Findings further reveal that real-time integration enhances design adaptability and decision-making efficiency. This study concludes that the integration of parametric design and structural rationalization represents a robust and scalable paradigm for contemporary architectural engineering, offering significant implications for sustainability, performance optimization, and interdisciplinary collaboration.

Abstract

Increasing exposure of infrastructure systems to extreme hazards, aging effects, and climate-induced uncertainties has revealed fundamental limitations of conventional strength- and safety-oriented design approaches. Structural performance can no longer be evaluated solely in terms of damage prevention, but must also account for functionality loss, system interdependencies, and recovery capacity. This study aims to reengineer the concept of structural resilience by developing a multiscale framework that integrates resilience explicitly into performance-based infrastructure design. The research adopts an analytical and framework-oriented methodology, combining critical synthesis of performance-based design theories, structural resilience metrics, and systems engineering concepts. Multiscale linkages are established among component-level behavior, system-level functionality, and network-level performance, with explicit consideration of temporal recovery processes. The results demonstrate that resilience is an emergent and time-dependent system property that cannot be inferred directly from component-level performance indicators. Local strengthening strategies are shown to yield limited resilience gains unless supported by system redundancy, connectivity, and recovery-oriented design. The proposed framework reveals hidden vulnerabilities and recovery bottlenecks that remain unaddressed in conventional performance-based approaches. The study concludes that effective resilience-oriented infrastructure design requires a paradigm shift toward multiscale, system-aware, and recovery-informed performance objectives. Embedding these principles into performance-based design provides a robust foundation for enhancing infrastructure reliability, functionality, and societal resilience under extreme and uncertain conditions.

Abstract

Ovarian cancer is one of the most lethal gynecologic malignancies due to late diagnosis. Early detection is critical for improving survival rates, yet current screening methods are inadequate. To identify and validate non-invasive biomarkers for the early detection of ovarian cancer, focusing on improving diagnostic accuracy and patient outcomes. This study utilized proteomic and genomic approaches, including mass spectrometry for protein profiling and next-generation sequencing for analyzing cfDNA and miRNAs. Blood samples from patients with early-stage ovarian cancer, healthy controls, and individuals with benign conditions were analyzed. The combination of CA-125 and HE4 biomarkers significantly increased sensitivity (85%) and specificity (90%) for early detection of ovarian cancer compared to CA-125 alone. Proteomic analysis identified significant differences in protein profiles between cancer patients and healthy controls. Genomic analysis revealed specific mutations in cfDNA associated with ovarian cancer. The study demonstrates that a combination of CA-125 and HE4, along with multi-omic approaches, can enhance the early detection of ovarian cancer, providing a basis for the development of more accurate diagnostic tests. Further clinical trials are necessary to validate these findings.
