Incorporating an illumination optimization plan into the worker safety management process in industrials is essential since the quality of workplace illumination has a significant impact on workers' well-being. The purpose of this study was to optimize illumination conditions in industrial workspaces using light-emitting diode (LED) technology with a color temperature of 6500 K and a CRI of 85 %. To accomplish this, the DIALux illumination simulation tool was utilized.

Objectives: Since the formation of skeletal malocclusions is closely linked to general craniofacial development, it is crucial to understand the anatomy and growth patterns of the skull base. This study aimed to assess the morphometry of the occipital condyle (OC) on CBCT scans of Class III skeletal malocclusion subjects and compare the findings with those of skeletal Class I malocclusion subjects.
Methods: A retrospective analysis was performed on CBCT images based on predefined inclusion and exclusion criteria.

We report the case of a 9-year-old male with severe congenital pulmonary valve stenosis referred to our centre for percutaneous valvotomy. On admission, trans-thoracic echocardiogram confirmed a unicuspid pulmonary valve with a peak/mean pulmonary valve gradient of 91/53 mmHg and a pulmonary annulus of 13.8 mm (-0.

Background: Root remodeling is one form of valve-preserving root replacement for aortic regurgitation and root aneurysm. The objective of this review was to summarize our experience with root remodeling encompassing 28 years.
Methods: We performed root remodeling in 1,189 patients (76% male, mean age 53±14 years) between October 1995 and September 2022.

Background: Isolated repair of the regurgitant tricuspid aortic valve has become an increasingly practiced alternative to replacement, even though durability data are scarce. We analyzed the midterm results of tricuspid aortic valve repair to determine whether the mechanism of regurgitation or operative technique influences the results.
Methods: Between December 1997 and August 2014, 264 patients underwent isolated tricuspid aortic valve repair in our institution.
