The epidemiology of male lower urinary tract symptoms associated with benign prostatic hyperplasia: Results of 20 years of Korean community care and surveys.

Purpose: To investigate the prevalence of lower urinary tract symptoms/benign prostatic hyperplasia in a Korean population.

Materials And Methods: The Korean Prostate & Voiding Health Association provided free prostate-related community health care and conducted surveys in all regions of Korea from 2001 to 2022 with the cooperation of local government public health centers. A total of 72,068 males older than 50 were surveyed and analyzed.

Fluorine plasma treatment on carbon-based perovskite solar cells for rapid moisture protection layer formation and performance enhancement.

A fluorine plasma-treated carbon electrode is used in HTM-free perovskite solar cells for high efficiency and moisture resistance. The fluorine-treated device with a champion power conversion efficiency (PCE) of 14.86% is achieved with a highly enhanced FF (FF = 0.

ZnO quantum dot-decorated carbon nanofibers derived from electrospun ZIF-8/PVA nanofibers for high-performance energy storage electrodes.

Hierarchical fibrous structures composed of ZnO quantum dots, amorphous carbons, and carbon nanofibers are synthesized via a single carbonization process of electrospun ZIF-8/PVA nanofibers. This newly designed electrode material for supercapacitors exhibits outstanding electrochemical performances with high capacitance, reliable rate capability, and long cycle life.

High-Performance Three-Dimensional Mesoporous Graphene Electrode for Supercapacitors using Lyophilization and Plasma Reduction.

In this study, a three-dimensional (3D) mesoporous plasma-reduced graphene oxide web (mPrGO web) was fabricated via lyophilization of graphene oxide (GO) solution and subsequent plasma reduction. The lyophilized graphene oxide web (GO web) was successfully reduced by a short plasma treatment (<2 s) using a commercially available plasma apparatus. The degree of reduction of the mPrGO web was determined by the applied plasma power (W) of the apparatus; the optimum power level for effective reduction was identified.

A comparative study of the electrorheological properties of various N-doped nanomaterials using ammonia plasma treatment.

A new, simple method is reported to enhance the electrorheological (ER) activity of nanomaterials. Plasma treatment was the ideal technique owing to its ease of use, versatility, and common usage in mass production. Multi-gram quantities of ER nanomaterials with different morphologies, sizes, and compositions were successfully treated by ammonia plasma.
