Relationship between optimism, emotional intelligence, and academic resilience of nursing students: the mediating effect of self-directed learning competency.

Background: The evolution toward future education following the 4th industrial revolution and the coronavirus disease 2019 (COVID-19) pandemic have changed nursing education dramatically. Online classes have become a new paradigm of education, and are expected to develop and be maintained in various forms even after the end of COVID-19. Therefore, attention is focused on finding ways to improve learners' achievements in a distance learning environment.

University Students' Sleep and Mental Health Correlates in South Korea.

Sleep closely relates to emotional instability. Recent studies report an increase in young adults’ poor sleep and associated mental health problems, including attention deficit hyperactivity disorder (ADHD), anxiety, depression, and so on. However, the information on related modifiable factors of these variables is still lacking.

Quality of Gerontological Nursing and Ageism: What Factors Influence on Nurses' Ageism in South Korea?

With the aging of the population, age-related problems are emerging, which has caused age discrimination. Particularly, most nurses care for a large number of old patients in the clinical setting. Nurses' attitude toward the clients has a significant effect on the quality of nursing, so it is time to identify their perspective to the aged.

Metacognitive beliefs predict early response to pharmacological treatment in patients with obsessive-compulsive disorder.

Rationale: Metacognitions, beliefs that monitor or control thoughts and coping, are considered to be important components for development and maintenance of obsessive-compulsive disorder (OCD).

Objectives: This study prospectively investigated whether metacognitive beliefs can predict early treatment response after serotonin reuptake inhibitor (SRI) initiation in patients with OCD.

Methods: Drug-naïve or medication-free patients with OCD (N = 156) were assessed for various characteristics, including metacognitions.

Anti-Diabetic Effects of Acankoreagenin from the Leaves of Acanthopanax Gracilistylus Herb in RIN-m5F Cells via Suppression of NF-κB Activation.

Diabetes mellitus is a chronic degenerative disease that causes long-term complications and represents a serious public health problem. In this manuscript, acankoreagenin isolated from the leaves of (LAG) is thought to possess excellent anti-diabetic properties. In vitro, anti-diabetic activities were assessed based on the inhibitory activities with α-glucosidase (IC 13.

Multidimensional impulsivity as a mediator of early life stress and alcohol dependence.

Early life stress (ELS) leads to increased susceptibility to serious psychiatric problems such as alcohol dependence, but the mechanisms through which ELS affects alcohol dependence are unclear. We investigated the mediating role of multi-dimensional impulsivity in the associations between ELS and alcohol dependence. 330 male patients with alcohol dependence (mean age = 48.

Association between glutamate transporter gene polymorphisms and obsessive-compulsive disorder/trait empathy in a Korean population.

Accumulating evidence suggests that the glutamatergic system plays a major role in the pathophysiology of obsessive compulsive disorder (OCD) and empathic processing. Particularly, genetic influence of glutamate transporter gene (SLC1A1) on OCD has been frequently replicated in previous studies, but several studies did not replicate the result. Therefore, we aimed to replicate the associations between the SLC1A1 and OCD in a Korean population.

Oxytocin receptor gene polymorphisms exert a modulating effect on the onset age in patients with obsessive-compulsive disorder.

The oxytocin receptor (OXTR) is a potential candidate in the pathophysiology of obsessive-compulsive disorder (OCD). The present study investigated the association between common single-nucleotide polymorphism (SNPs) of the OXTR gene and the affected status of OCD or distinct clinical subtypes of OCD including the age at onset and symptom dimensions. Ten SNPs of OXTR were examined in 615 patients with OCD and 581 healthy controls.

Common variants of HTR3 genes are associated with obsessive-compulsive disorder and its phenotypic expression.

Evidence from literature supports the existence of associations between serotonin-related genetic variants and obsessive-compulsive disorder (OCD), but few studies have explored the involvement of serotonin receptor type 3 genes (HTR3) in OCD. To identify whether HTR3 variability affects an individual's susceptibility to OCD, we examined 10 HTR3 variants in 596 individuals with OCD and 599 controls. A significant difference existed in the genotypic distribution of the HTR3B variant rs1176744 between individuals with OCD and controls (odds ratio [OR] = 0.

Composition Analysis and Inhibitory Effect of Sterculia lychnophora against Biofilm Formation by Streptococcus mutans.

Pangdahai is a traditional Chinese drug, specifically described in the Chinese Pharmacopoeia as the seeds of Sterculia lychnophora Hance. Here, we separated S. lychnophora husk and kernel, analyzed the nutrient contents, and investigated the inhibitory effects of S.

Comparison of quality of sleep, depression, and life satisfaction between older adults in nursing homes and long-term care hospitals in Korea.

Aim: The purpose of the present study was to identify the sleep quality, depression, and life satisfaction between nursing home and long-term care hospital residents.

Methods: Data was collected through a structured questionnaire survey of 61 nursing home residents and 74 long-term care hospital residents. Descriptive statistics, t-test, χ -test, anova, Pearson's correlation were used to analyze the data.
