Societal concerns about air quality in East Asia are still growing despite country-level efforts to reduce air pollution emissions. In coping with this growing concern, the government and the public demand a longer‑lead forecast of air quality to ensure sufficient response time until society prepares for countermeasures such as a temporary reduction of specific emission sources. Here we propose a novel method that produces skillful seasonal forecasting of wintertime (December to February) PM concentration over South Korea.

Palliative care should be integrated into routine disease management for all patients with serious illness, regardless of settings or prognosis. The purposes of this integrative review were to identify the features of randomized controlled trials for adult patients with heart failure and to provide basic references for the development of future trials. Using Whittemore and Knafl's integrative literature review method, comprehensive searches of the PubMed, Cochrane Library, CINAHL, EMBASE, and Korean databases were conducted, integrating keywords about heart failure and palliative care interventions.

Background: The number of gastric cancer survivors has been increasing, and such survivors experience various changes in their lives post-recovery. Adapting to these changes requires appropriate interventions that can improve their quality of life (QoL). This study was conducted to investigate the factors affecting the QoL of gastric cancer survivors and provide basic data for effective intervention.

Purpose: This study aimed to systematically review published research on the use of the teach-back method among cancer patients and provide basic data for developing effective nursing interventions.

Methods: Using a PICOS (Population, Intervention, Comparisons, Outcomes, Study Designs) framework, we reviewed 246 studies from selected electronic databases-CINAHL, EMBASE, PubMed, PsycInfo, RISS, KISS, DBpia, NDSL, and KCI-and selected five studies for further analysis. We evaluated the reference quality using Cochrane's risk of bias and risk of bias assessment tool for non-randomized studies, following which we performed reviews and analyses.

Patients with end-stage liver disease undergo repetitive patterns of recovery and deterioration and are burdened with uncertainty. Although quality of life is low in patients with end-stage liver disease and their family members, few studies have been conducted to identify what palliative care should be provided for them. This integrative review aimed to explore palliative care for patients with end-stage liver disease, focusing on the components and outcome measurements for further research.

Initially identified as a protein implicated in human mental deficit, cereblon (CRBN) was recently recognized as a negative regulator of adenosine monophosphate-activated protein kinase (AMPK) in vivo and in vitro. Here, we present results showing that CRBN can effectively regulate new protein synthesis through the mammalian target of rapamycin (mTOR) signaling pathway, a downstream target of AMPK. Whereas deficiency of Crbn repressed protein translation via activation of the AMPK-mTOR cascade in Crbn-knock-out mice, ectopic expression of the wild-type CRBN increased protein synthesis by inhibiting endogenous AMPK.
