Forest-based interventions are a promising alternative therapy for enhancing mental health. The current study investigated the effects of forest therapy on anxiety, depression, and negative and positive mental condition through a meta-analysis of recent randomized controlled trials, using the PRISMA guideline. Of 825 articles retrieved from databases including PubMed, EMBASE, CINAHL, Cochrane, and PsycINFO, 6 met the inclusion criteria. The results of this study showed that forest-based interventions improved the mental health of participants in the intervention groups when compared to those in the control groups. Thirty-four outcome variables were analyzed from six studies. The overall effect size of the forest therapy programs was 1.25 (95% CI = 0.93–1.57, p < 0.001), which was large and statistically significant. These findings imply that forest-based interventions can improve mental health as a nonpharmacological intervention. This study is significant in that it is a meta-analysis of mental health that included only high-quality domestic and international RCTs. In future studies, more RCTs related to various forest interventions and studies involving many participants should be undertaken, which will complement heterogeneity in future meta-analysis studies.

The present study aimed to confirm latent classes in health-related quality of life (HRQOL) in older adults and investigate the characteristics of participants in each class. It aimed to provide basic data to develop interventions for each quality-of-life class by analysing the predictors of each class. Secondary data from a community health survey in G province since 2019 found a total of 41,872 participants. Of them, 9027 were 65 years or older and residing in G Province in 2019, participated in this study. Mplus 8.5 was used to conduct a latent class analysis of five domains of HRQOL. Four latent classes in the HRQOL of older adults, namely, stable type, physical disability type, emotional disability type, and crisis type were found. Certain variables predicted these classes. Based on the findings of the present study, training on functional mobility and balance to prevent falls in older populations and individualised programmes to promote mental health in them should be provided. Moreover, policies should increase medical accessibility and provide social support for older people with low-incomes. Additionally, since physical, psychological, and social health in older adults are inter-connected, a comprehensive care plan is needed to improve their HRQOL.

This study evaluated the recognition and attitude toward microplastic and zero waste among college students and investigated the factors influencing their zero-waste behaviours. The study was conducted from 20 August 2021 to 10 September 2021, including students at a university in G metropolitan city, Republic of Korea. A total of 196 data were analysed. Statements were developed to verify how the use of disposables and the recognition, attitude, and behaviours related to zero waste were affected during the COVID-19 pandemic. Family type and usage of disposables were the factors affecting zero-waste behaviour in Model 1. In Model 2, which included the subcategory of zero-waste recognition, the health effects of microplastics and environmental preservation were significant factors. In Model 3, which included the subcategory of zero-waste attitude, the health effects of microplastics (β = 0.149, p = 0.016), use of eco-friendly products (β = 0.342, p < 0.001), and environmental preservation (β = 0.317, p < 0.001) were significant factors. The use of plastic products increased dramatically during the COVID-19 pandemic. Research and education are needed to promote zero-waste behaviours with a focus on microplastics. Raising awareness of the health effects of microplastics can enhance the effectiveness of education.

Patients with coronavirus disease 2019 (COVID-19) usually complain of fever, cough, and sore throat. This study examined the effects of aromatherapy on sore throat, nasal symptoms, stress, fatigue, and sleep quality by administering it to adults with post-COVID-19 condition. This study was conducted in a randomised controlled design. Its target population were adults who were released from COVID-19 quarantine treatment within 45 days from infection onset and capable of performing daily activities after isolation treatment. The participants were randomised into aromatherapy group (AG) and control group (CG). To test experimental treatment effects, the levels of sore throat, nasal symptoms, stress, fatigue and sleep quality were measured at the baseline (pre-test) and after the trial (post-test), using the numerical rating scale for sore throat, stress and fatigue, the Total Nasal Symptoms Score for nasal symptoms, and the Korean Version of Modified Leeds Sleep Evaluation Questionnaire for quality of sleep. After experimental treatment, there was a significant difference in sore throat in AG compared to CG on the 3rd day (t=-2.022 p=0.048) and 4th day (t=-2.450, p=0.017) of treatment. There was also a significant difference in fatigue between AG and CG on the 2nd day(t=-2.748, p=0.008), 3rd day (t=-2.948, p=0.005) and 4th day (t=-3.084, p=0.003) of treatment. There was no significant difference in TNSS, stress, and sleep quality between the two groups after the experimental treatment. Inhaling aroma essential oils reduced sore throat and fatigue in adults with post-COVID-19 condition, demonstrating the feasibility of aromatherapy as an effective treatment. The study was registered with Clinical Research Information Service (KCT0008029).

Purpose: The aim of this meta-analysis was to identify the effects of horticultural therapy on Korean elderly with dementia.Methods: We searched the PubMed, EMBASE, Cochrane, CINAHL, and eight domestic databases, until February 2021. Data extraction and the risk of bias assessment were independently conducted by two authors. Standardized mean differences (SMDs) with 95% confidence intervals (CIs) were calculated using a random-effects meta-analysis.Results: Of the 478 studies retrieved from the databases, 21 studies were included in the final analysis. A total of 93 outcome variables were analyzed in 21 literatures. The overall effect size of the horticultural treatment program was 0.91 (95% CI: 0.74~1.09, p<.001), which was statistically significant. Compared to the control group, horticultural therapy improved cognitive functions (SMD=0.71, 95% CI: 0.42~0.99, I2=79.9%), psychosocial functions (SMD=1.01, 95% CI: -0.70~1.31, I2=67.8%), and physical functions (SMD=1.05, 95% CI: 0.77~1.33, I2=72%) in Korean elderly with dementia.Conclusion: This meta-analysis found that horticultural therapy improved the cognitive, psychosocial, and physical functions of dementia patients compared to subjects in the control group.

Purpose: The purpose of this study was to investigate the trends in domestic and foreign studies on the various effects of parental phubbing behavior on adolescent children.Methods: This scoping review was conducted according to the Joanna Briggs Institute (JBI) protocol. Literature published in five foreign databases and four domestic databases was searched. Two researchers independently reviewed and selected the literature, and the extracted data included the author, publication year, country of study, research methodology, study participants, independent variables and tools used, dependent variables, and influencing factors.Results: A total of 575 articles were identified, and 43 articles were finally included in the analysis. The publication years ranged from 2018 to 2022, and most studies were cross-sectional studies. The dependent variables were broadly classified into cognitive-behavioral, psychological, and social variables, with smartphone addiction and depression being the most commonly reported.Conclusion: This study represents a significant attempt to investigate the trends in domestic and foreign research on the effects of parental phubbing on adolescent children, and is expected to be utilized as a foundation for developing programs to promote mental health, including interpersonal relationships for adolescents.
