Fabrication of 3D Printed Polylactic Acid/Polycaprolactone Nanocomposites with Favorable Thermo-Responsive Cyclic Shape Memory Effects, and Crystallization and Mechanical Properties.

In this work, 3D printed polylactic acid (PLA)/polycaprolactone (PCL) nanocomposites with favorable thermo-responsive cyclic shape memory effects (SMEs) and crystallization and mechanical properties were fabricated using a two-step method. First, an isocyanate-terminated PCL diol (PCL-NCO) was synthesized through the reaction between isocyanate groups of hexamethylene diisocyanate and active hydroxyl groups of PCL diol, and its physicochemical properties were characterized. A PLA/PCL blend with a PCL content of 50 wt% was fabricated via fused filament fabrication (FFF) 3D printing, and the influence of the PCL-NCO on the SME of the PLA/PCL blend was studied.

Domestic Violence in Single- and Multi-child families in China: a ten-year comparison in the same communities.

Chinese one-child policy has been practiced for more than 30 years. With the policy that one couple can have two children being fully implemented from Jan 1, 2016 in China, the families with two or more children are increasing, and the family size, family structure and family relationship has been largely changed. Little is known about the difference in domestic violence (DV) among single- and multi-child families in China.

Effective intervention in domestic violence in Chinese communities: an eight-year prospective study.

Background: Domestic violence is increasing in China. To explore the effective intervention, we intervened three large independent Chinese communities with different approaches over an eight-year period from 2005 to 2012, with a fourth independent community as a peer control.

Methods: The intervention approaches included the psychological intervention with traditional Chinese culture characteristics, the social governance and the poverty relief.

[An epidemiological study on domestic violence in Hunan, China].

Objective: To investigate the prevalence of domestic violence (DV) in Hunan.

Methods: Using a multi-stage sampling strategy, 9451 households involving 32 720 persons in urban, rural and industrial areas in Hunan, China were studied. Multiform clue investigation and face-to-face interviews were combined to investigate the prevalence of DV.
