Effects of Ego-resilience Interventions among Children and Adolescents in Korea: A Meta-analysis / 정신간호학회지

PURPOSE: This study was a meta-analysis planned to exam effects of ego-resilience interventions among children and adolescents in Korea. METHODS: Search for relevant articles included several electronic databases and hand-search from article references. Thirteen studies met inclusion criteria from 1,638 studies. Comprehensive Meta-Analysis (version 3) and Review Manager (version 5) were used to analyze effect sizes, investigate possible causes of heterogeneity and check publication bias with a funnel plot and its trim-and-fill analysis. RESULTS: Overall effect size of ego-resilience interventions were medium (Hedges'g=0.66) and medium heterogeneity (I²=54%). Subgroup analysis was performed to estimate causes of heterogeneity. The effect size for normal populations (g=0.70) was larger than for risk populations (g=0.64). Interventions for primary school students (g=0.74) were more effective than interventions for adolescents (g=0.51). Interventions in the community (g=0.72) shown larger effect size than intervention at school (g=0.51). Art therapy (g=0.79) had a better effect than cognitive behavior therapy (g=0.62). Interventions with over 1,000 minutes (g=1.10) and intervention with over 11 sessions (g=1.40) were effective. This study found no significant publication bias. CONCLUSION: Based on current findings, there is obvious evidence that ego-resilience interventions have significant effects in improving ego-resilience among children and adolescents in Korea.

Taxonomic Studies on the Genus Crepidotus in Korea

For investigation of the species diversity of the Genus Crepidotus in Korea and constructing a key to Korean Crepidotus species, a total of 65 specimens, collected from 18 locations from 1982 to 2002, were observed for morphological characters of carpophores and other features. All the specimens have been preserved in the herbarium of the National Institute of Agricultural Sciences and Technology, R.D.A., Suwon, Korea. The specimens were identified according to the classification systems given by Hesler and Smith(1965), Nordstein(1990), Orton(1960), Pilat(1948), Senn-Irlet(1991, 1992, 1993) and Singer(1951, 1973, 1986). In this study, a total of 10 Crepidotus species were confirmed. Among them, Korean common names were designated to six unrecorded species as follows: C. uber; C. hygrophanus; C. latifolius; C. obscurus; C. subverrucisporus; and C. circinatus. A key to 10 Crepidotus species has been constructed.
