Nutritional Risk, Depression, and Physical Function in Older People Living Alone.

This study investigated depression and physical function as factors associated with nutritional risk in older adults living alone. The study included 2896 people 65 years or older who lived alone. Data were collected in South Korea between September and November 2020.

The Effects of Manual Acupuncture on Mitochondrial Fusion and Fission Gene Expression in Rat Spleen.

Background: A significant amount of research has been conducted to establish the validity of acupuncture, and it has been demonstrated through animal disease model studies that acupuncture influences mitochondrial changes. However, to more accurately examine the mechanisms of acupuncture treatment effectiveness in pathological models, it is crucial to investigate changes in disease-free animals. Among various hypotheses regarding the effects of acupuncture on the body, we focused on the result that acupuncture stimulation is related to mitochondria.

Factors Related to Life Satisfaction of Older Adults at Home: A Focus on Residential Conditions.

This study examined which residential conditions increase older adults’ life satisfaction at home. We used data from 8903 participants over 65 years old who did not need help in their daily lives from a 2020 survey of older adults conducted by the Korea Institute for Health and Social Affairs. Data analysis was conducted using descriptive statistics, independent sample t-test, Pearson correlation analysis, and hierarchical multiple regression with weights.

College Life Adjustment, Life Stress, Career Barriers, and Career Decision-Making Self-Efficacy of College Students Who Have Experienced COVID-19 in South Korea.

University life is challenging for students, given the college life adjustment, life stress, career barriers, and career decision-making self-efficacy required. COVID-19 has made this even more complex. This study investigated the relationships among these factors in college students who experienced COVID-19.

Nursing Students' Acceptance Intention of a Smart Device, Information Literacy, and Problem-Solving Confidence.

The purpose of this study was to investigate the relationship between nursing students' acceptance intention of a smart device, information literacy, and problem-solving confidence to explore the factors that may improve nursing students' problem-solving confidence. Data were collected from 450 nursing students between July and August 2019 in two cities in Korea. The results showed that there is a positive correlation between problem-solving confidence and acceptance intention (r = 0.

Smartphone use patterns and problematic smartphone use among preschool children.

Background: The purpose of the present study was to identify smartphone use patterns associated with problematic smartphone use (PSU) among preschool children. Little is known about PSU patterns in younger children, although the age for first smartphone use is decreasing.

Methods: We applied a cross-sectional study design to analyze data obtained from a nationwide survey on smartphone overdependence conducted in 2017 by the South Korean Ministry of Science and ICT and the National Information Society Agency.

Temporal Dynamics of Visually Induced Motion Perception and Neural Evidence of Alterations in the Motion Perception Process in an Immersive Virtual Reality Environment.

Even though reciprocal inhibitory vestibular interactions following visual stimulation have been understood as sensory-reweighting mechanisms to stabilize motion perception; this hypothesis has not been thoroughly investigated with temporal dynamic measurements. Recently, virtual reality technology has been implemented in different medical domains. However, exposure in virtual reality environments can cause discomfort, including nausea or headache, due to visual-vestibular conflicts.

Smartphone Use Patterns of Smartphone-dependent Children.

Purpose: The purpose of this study was to identify the smartphone use patterns of smartphone-dependent children.

Methods: The study design was a cross-sectional descriptive study. The data were derived from the 2017 survey on smartphone overdependence conducted by the Ministry of Science and ICT and the National Information Society Agency.

Developing a Diagnostic Decision Support System for Benign Paroxysmal Positional Vertigo Using a Deep-Learning Model.

: Diagnosis of benign paroxysmal positional vertigo (BPPV) depends on the accurate interpretation of nystagmus induced by positional tests. However, difficulties in interpreting eye-movement often can arise in primary care practice or emergency room. We hypothesized that the use of machine learning would be helpful for the interpretation.

Feasibility of Eye Tracking Assisted Vestibular Rehabilitation Strategy Using Immersive Virtual Reality.

Objectives: Even though vestibular rehabilitation therapy (VRT) using head-mounted display (HMD) has been highlighted recently as a popular virtual reality platform, we should consider that HMD itself do not provide interactive environment for VRT. This study aimed to test the feasibility of interactive components using eye tracking assisted strategy through neurophysiologic evidence.

Methods: HMD implemented with an infrared-based eye tracker was used to generate a virtual environment for VRT.

Intention to leave among staff nurses in small- and medium-sized hospitals.

Aims And Objectives: To explore the factors associated with the intention to leave among nurses in small- and medium-sized hospitals and to determine the predictors about work environment and rewards.

Background: Compared with large hospitals, insight into the working conditions, rewards and turnover of nurses working for these hospitals is lacking internationally.

Design: Cross-sectional study design.

Synergistic Effect between Cryptotanshinone and Antibiotics against Clinic Methicillin and Vancomycin-Resistant Staphylococcus aureus.

Cryptotanshinone (CT), a major tanshinone of medicinal plant Salvia miltiorrhiza Bunge, demonstrated strong antibacterial activity against clinic isolated methicillin and vancomycin-resistant Staphylococcus aureus (MRSA and VRSA) in this experiment. The CT was determined against clinic isolated MRSA 1-16 with MIC and MBC values ranging from 4 to 32 and 8 to 128  μ g/mL; for MSSA 1-2 from 16 to 32  μ g/mL and 64 to 128  μ g/mL; for VRSA 1-2 from 2 to 4  μ g/mL and 4 to 16  μ g/mL, respectively. The range of MIC50 and MIC90 of CT was 0.
