Rapid urbanization has significantly altered landscape environments in both urban and rural regions, and these landscapes have been demonstrated to play a pivotal role in human well-being. This study develops a coherent framework that integrates landscape change, landscape ecological indicators, and landscape preferences within the context of the evolving landscape environments of rural communities in Taiwan. Four distinct types of rural communities were selected, and a quantitative methodology was employed to investigate the variations and transformations in landscape preferences among rural residents in the context of landscape change.

This study investigated the closed-loop recycling of 3D-printed wood fiber (WF)-filled polylactic acid (PLA) composites via fused filament fabrication (FFF). The WF-PLA composites (WPCs) were extruded into WPC filaments (WPCs) to produce FFF-printed WPC parts (WPCs). The printed WPCs were reprocessed three times via extrusion and 3D-printing processes.

Wood fibers (WFs) were treated at a fixed heat temperature (180 °C) for 2-6 h and added to a polylactic acid (PLA) matrix to produce wood-PLA composite (WPC) filaments. Additionally, the effects of the heat-treated WFs on the physicomechanical properties and impact strength of the WPC filaments and 3D-printed WPC parts using fused filament fabrication (FFF) were examined. The results revealed that heat-treated WFs caused an increase in crystallinity and a significant reduction in the number of pores on the failure cross section of the WPC filament, resulting in a higher tensile modulus and lower elongation at break.

The demand for highly specific and complex materials has made the development of controllable manufacturing processes crucial. Among the numerous manufacturing methods, casting is important because it is economical and highly flexible regarding the geometry of manufactured parts. Since solidification is an important stage in the casting process that influences the properties of the final product, the development of a controllable solidification process using modeling methods is necessary to create superior structural properties.

Purpose: Aberrant right subclavian artery (ARSA) associated with Kommerell's diverticulum (KD) is a common congenital arch anomaly. It can be complicated by type B aortic dissection (TBAD) or aneurysmal formation at its ostium. Recently, hybrid repair with thoracic endovascular aortic repair (TEVAR) has appeared to be more favorable.

Objective: Both temporomandibular disorders (TMDs) and sleep bruxism (SB) are known to be destructive to the masticatory system. However, the association between the 2 conditions is poorly understood. The aim of our study was to assess the relationship between TMD and SB through the signs and symptoms in 2 patient groups: TMD only and TMD with SB.

Aminoacyl-tRNA synthetase cofactors play important roles in coordinating aminoacylation and translation. In this study, we describe an additional function of the fission yeast minoacyl-tRNA ynthetase ofactor (Asc1) in translation. We found that Asc1 directly binds and stabilizes the interaction between small ribosomal protein Rps0A/uS2 and eukaryotic initiation factor 3a (eIF3a).

The purpose of this study was to develop a gellan gum-based multifunctional embolic agent. Calibrated spherical gellan gum and nanoparticle-containing gellan gum microspheres were prepared via water-in oil emulsification method. Self-assembled nanoparticles composed of short-chain hyaluronic acid and polyethylenimine as the doxorubicin carrier were prepared.
