Objectives Maternal attachment to promote role development in mothers of preterm infants is critical for babies' optimal growth and development. However, few models specify how neonatal intensive care units (NICUs) and their environments work to foster postpartum attachment (PPA) after preterm birth. We investigated relationships of quality of family-centered care and NICU environmental stressors with maternal PPA, to determine whether these are mediated by mothers' psycho-emotional response and whether pathways to PPA are moderated by developmental immaturity (gestation, birthweight). Methods A cross-sectional study using structural equation modeling was conducted on 294 mothers of premature infants with experience in NICUs in over 49 tertiary hospitals in 12 cities or provinces of South Korea. Data were collected using Korean versions of instruments including the Quality of Family-centered Care, Parental Stressor Scale: NICU, and Maternal Postpartum Attachment Scale. Results Maternal self-representation was a key predictor of PPA ([beta] = .68), accounting for 42.2% of variance. Multi-group analysis indicated that NICU environmental stressor sensitivity ([beta] = .26) and maternal self-representation ([beta] = .67) were predictive of PPA in mothers of moderately preterm and low birthweight (32-36 weeks' gestation, 1500-2499 g birthweight) infants. Quality of family-centered developmental care ([beta] = .11) and NICU environmental stressor sensitivity ([beta] = - .16) had significant indirect effects on PPA through psycho-emotional responses.

Aim: This study aims to investigate the effect and methods of cryotherapy in reducing swelling after total knee arthroplasty. Design: Systematic review. Methods: We searched PubMed, Embase, CINAHL, Cochrane Library, KoreaMed, KERIS and National Science Digital Library for randomized controlled trials on 19 August 2021. This systematic review was conducted according to the PRISMA 2009 checklist. Results: A total of eight randomized controlled trials were systematically reviewed to determine the effect and methods of cryotherapy on reducing postoperative swelling. The effects were not significantly different in six studies. Application time per cryotherapy session was 10–20 min when using an ice pack and up to 48 h when using an automated device. The duration ranged from 2 days to 1 week or until discharge, and the frequency varied from 2 to 72 times per day. [ABSTRACT FROM AUTHOR]

Atmospheric concentration of sulfur dioxide (SO2) was intermittently measured at an air quality monitoring (AQM) station in the Yong-san district of Seoul, Korea, between 1987 and 2013. The SO2level was compared with other important pollutants concurrently measured, including methane (CH4), carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO2), ozone (O3), and particulate matter (PM10). If split into three different periods (period 1, 1987–1988, period 2, 1999–2000, and period 3, 2004–2013), the respective mean [SO2] values (6.57 ± 4.29, 6.30 ± 2.44, and 5.29 ± 0.63 ppb) showed a slight reduction across the entire study period. The concentrations of SO2are found to be strongly correlated with other pollutants such as CO (r= 0.614,p= 0.02), which tracked reductions in reported emissions due to tighter emissions standards enacted by the South Korean government. There was also a clear seasonal trend in the SO2level, especially in periods 2 and 3, reflecting the combined effects of domestic heating by coal briquettes and meteorological conditions. Although only a 16% concentration reduction was achieved during the 27-year study duration, this is significant if one considers rapid urbanization, an 83.2% increase in population, and rapid industrialization that took place during that period. Implications: Since 1970, a network of air quality monitoring (AQM) stations has been operated by the Korean Ministry of Environment (KMOE) for routine nationwide monitoring of air pollutant concentrations in urban/suburban areas. To date, the information obtained from these stations has provided a platform for analyzing long-term trends of major pollutant species. In this study, we examined the long-term trends of SO2levels and relevant environmental parameters monitored continuously in the Yong-san district of Seoul between 1987 and 2013. The data were analyzed over various time scales (i.e., monthly, seasonal, and annual intervals). The results obtained from this study will allow us to assess the effectiveness of abatement strategy and to predict future concentrations trends in association with future abatement strategies and technologies.
