Association between in-hospital exclusive breastfeeding and subsequent exclusive breastfeeding until 6 months postpartum in Japan: A cross-sectional study.

Breastfeeding practices during hospitalisation may influence subsequent breastfeeding practices; however, this association has not been well studied in Japan. Therefore, we aimed to examine the association between exclusive breastfeeding (EBF) during hospitalisation and that under 6 months and describe the change in breastfeeding patterns from the first to the sixth month based on the breastfeeding status during hospitalisation. This nationwide cross-sectional internet survey conducted in Japan included 1,433 postpartum women of < 6 months who underwent live singleton deliveries between January 2021 and August 2021.

Enhancing hospital quality management and patient safety in Vietnam: a technical assistance project utilizing online solutions during COVID-19 pandemic.

Since 2015, the National Center for Global Health and Medicine in Japan has been conducting a technical assistance project for improving patient safety in Vietnamese hospitals. During the COVID-19 pandemic, the project conducted a patient safety training program utilizing online solutions for participants from Vietnam. This resulted in an increase in the number of participants, and ensured access from remote locations.

Coverage-dependent geometries of nanowires on Ge(0 0 1)-Au surfaces: modification of trenches.

Despite intense research the microscopic atomic structure of Au-induced nanowires on Ge(0 0 1) substrates is still under discussion. We analyse a variety of structural models for Au-induced nanowires on the Ge(0 0 1) surface using first-principles calculations. Here we focus on subridge modifications at higher Au coverages and study geometries based on the giant missing row model with Ge-Ge dimers in the grooves between the nanowires due to replacing them by Ge-Au heterodimers or Au-Au homodimers.

Metal-to-Insulator Transition in Au Chains on Si(111)-5×2-Au by Band Filling: Infrared Plasmonic Signal and Ab Initio Band Structure Calculation.

The Si(111)-5×2-Au surface is increasingly of interest because it is one of the rare atomic chain systems with quasi-one-dimensional properties. For the deposition of 0.7 monolayers of Au, these chains are metallic.

Metallic Properties of the Si(111) - 5 × 2 - Au Surface from Infrared Plasmon Polaritons and Ab Initio Theory.

The metal-atom chains on the Si(111) - 5 × 2 - Au surface represent an exceedingly interesting system for the understanding of one-dimensional electrical interconnects. While other metal-atom chain structures on silicon suffer from metal-to-insulator transitions, Si(111) - 5 × 2 - Au stays metallic at least down to 20 K as we have proven by the anisotropic absorption from localized plasmon polaritons in the infrared. A quantitative analysis of the infrared plasmonic signal done here for the first time yields valuable band structure information in agreement with the theoretically derived data.

Ga-rich limit of surface reconstructions on GaAs(001): atomic structure of the (4 x 6) phase.

The Ga-rich reconstruction of the GaAs(001) surface has been studied. Using scanning tunneling microscopy (STM), we have found the existence of a well-ordered (4 x 6) reconstruction under extreme Ga-rich conditions. A structure model, consisting of subsurface Ga-Ga dimers and surface Ga-As dimers, is proposed for the (4 x 6) surface.
