Industry Culture Matters: Sexual Harassment in the South Korean Film Industry.

This study analyzes factors of sexual harassment in the workplace based on sample survey data on women working in the Korean film industry ( = 449) using logistic regression analysis. It finds higher education, younger age, and union membership increase harassment risk, suggesting backlash against feminism post-#MeToo. A higher proportion of men at shooting locations raises harassment likelihood, reflecting the industry's unique conditions.

A synthetic approach to N-aryl carbamates via copper-catalyzed Chan-Lam coupling at room temperature.

A mild and efficient synthesis of N-arylcarbamates was achieved by reacting azidoformates with boronic acids in the presence of 10 mol % of copper chloride catalyst. The reaction proceeds readily in an open flask at room temperature without additional base, ligand, or additive. Rapid access to urea analogues via a two-step one-pot procedure is enabled by reacting N-arylcarbamates with aluminum-amine complexes.

Copper-catalyzed Chan-Lam coupling between sulfonyl azides and boronic acids at room temperature.

A mild and efficient method for the synthesis of N-arylsulfonamides in the presence of 10 mol % of CuCl is demonstrated. The reaction proceeds readily at room temperature in an open flask using a variety of sulfonyl azides and boronic acids without any base, ligand, or additive.

Blood flow resistance with vibration and its effect on blood cell migration.

The present study investigated the effect of transverse vibration on the hemo-rheological characteristics of blood flow using a newly designed pressure-scanning capillary viscometer. As a transverse vibration was applied, aggregated blood cells become disaggregated. Frequency of vibration was found to be the main parameter causing hemo-rheological changes.
