  • Background: This study investigated the effect of soil properties and soil bacterial community on early growth characteristics of wild-simulated ginseng (Panax ginseng C. A. Meyer) in coniferous and mixed forest experimental fields. Methods and Results: The soil bacterial community was analyzed using a high throughput sequencing technique (Illumina MiSeq sequencing). The relationship between the soil bacterial community, soil properties, and growth characteristics of wild-simulated ginseng were analyzed using principal coordinate analysis (PCoA) and the Pearson's correlation analysis. Soil properties and soil bacterial community showed significant difference with forest physiognomy. Results of Pearson's correlation analysis and PCoA showed that the soil properties (soil pH, organic matter, total nitrogen, and cation exchange capacity) and soil bacterial community had significant correlation with tree species ratio and early growth characteristics of wild-simulated ginseng. Conclusions: This study clearly demonstrated the effect of soil properties and soil bacterial community on early growth characteristics of wild-simulated ginseng in coniferous and mixed forest. Moreover, these results will help in the selection of suitable cultivation sites for wild-simulated ginseng.

  • Purpose: The purpose of this study was to determine relationships between academic achievement, clinical competence, and confidence in the clinical performance of nursing students, and to identify factors that influence them. Methods: This was a descriptive correlation study. Data were collected from 118 nursing students at a nursing college in Seoul. One-way variance analysis, Pearson's correlation coefficient, and multiple linear regression analysis were used to examine relationships between academic achievement, clinical competence, and confidence in clinical performance. Results: Clinical competence was related to academic achievement in students' previous semester and to students' academic scores in a fundamental of nursing course. Clinical competence showed a weak positive correlation with academic achievement in students' previous semester and academic scores in a fundamental of nursing course in both evaluations by the professor and students' self-evaluations. However, confidence in clinical performance had no significant correlation with academic achievement. The factor affecting the clinical competence was academic scores in a fundamental of nursing course, and factors affecting confidence in clinical performance were health status, personality, major suitability, and class satisfaction in a fundamental of nursing skills course. Conclusion: These findings indicate that students with high academic achievement have better clinical performance, but confidence in clinical performance is not related to academic achievement.

  • The purpose of this study was to investigate the several types of Korean parent's child rearing attitudes perceived by their children and the related variables. The study included the development of a "Children's Report of Korean Parent's Behavior Inventory"(CKPBI). Subjects were 1722 5th and 6th grade elementary school children from 5 urban cities in Korea. CKPBI and a Home Environment Questionnaire were used to gather data for the study. Stepwise multiple regression analysis, cross-tabulation analysis, Pearson correlation analysis, and factor analysis were conducted for the purpose of the study. A CKPBI which consists of 46 items for father's and 48 items for mother's was found as both a valid and reliable instrument for measuring the child rearing attitudes of Korean parents. A factor analysis resulted in identifying two factors both for mothers and fathers; they were the "Warmth factor" and "Rejection-Authority factor". Eight types of child rearing attitudes were found for Korean parents. The SES of family significantly predicted Korean parent's child rearing attitudes. The SES of the family, and sex of the child determined variations in Korean parents' child rearing attitudes. Maternal religion had a significant correlation with both boys' and girls' perceptions of parental attitudes. The results of this study indicate high inconsistency within each parent and high consistency between both parents.

  • The purpose of this study was to examine the validity and reliability of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)-VA3.0 in patients with hip and knee osteoarthritis (OA). The sample consisted of 301 patients who had received treatments at the physical therapy units of 5 medical institutions in Andong City in june 2006. Questionnaires on the WOMAC were recruited by 12 physical therapists. The internal structure and reliability of the scales were evaluated by means of item-internal consistency (Cronbach's alpha coefficient: ${\alpha}$), item-discriminant validity, and Pearson's relation coefficient. To explore construct validity, we conducted a principal component factor analysis with varimax rotation analysis. The criterion for factor extraction was an eigenvalue >1.0. The average age of the patients was 62.1 years. All WOMAC subscales (pain, stiffness, and physical function) were internally consistent with Cronbach's coefficients of .81, .91, and .80, respectively. The internal consistency reliability of item-each scale were also internally consistent with Cronbach's coefficient of .89 (Pearson's correlation coefficient: .71~.84), .93 (.89~.91), and .96 (.67~.91), respectively. However, high correlation was found among 3 items (.66~.83, .66~.67, and .67~.83), so the item-discriminant validity was low (${\alpha}$ coefficient: .81, .91, .80, respectively). The construct validity by factor analysis was low because it was not consistent With WOMAC-VA3.0. In conclusion, the results reported here confirm the reliability of the WOMAC in patients with OA of the hip and knee. The collection of information on the hip and knee osteoarthritis using this instrument was acceptable to patients. A further prospective multi-center study will be necessary to prove the construct validity.

  • The purpose of this study is to identify the level of polypharmacy use, drug knowledge, and drug misuse behavior in the elderly, and to understand the correlation between them and their effect on drug misuse behavior. The study design was a descriptive survey study, and the participants of the study were 215 elderly people from the local community center. The research tool used drug knowledge, drug misuse behavior, and the data collection period was from February 8 to 19, 2021. The data analysis were descriptive statistics, t-test, one-way ANOVA, Pearson's correlation coefficient, and regression analysis. As a result of the study, a significant correlation variable for the drug knowledge of the elderly showed a significant correlation with prescription and non-prescription, r=.145 (p<0.05), and r=.-. 136, which showed a negative significant correlation (p<0.05). As for the significant correlation variable in the drug misuse behavior of the elderly, when prescription and non-prescription were combined, there was a significant correlation with r=.256 (p<0.01), and when not using drugs, r=.-.225 was negative. showed a significant correlation (p<0.01). In terms of the effect on drug misuse behavior, chronic disease =.145, prescription and non-prescription use = .233, which had a positive effect, and non-prescription = -.328, indicating a negative and significant effect. The provision of education on the safe use of drugs by the elderly should first be provided in the community. In addition, we need systematic education and social support for the transmission of correct knowledge on multi-drug use by the elderly and for health management.

  • Purpose: This study investigated the effect of depression, life stress and resilience on quality of life among middle-aged women. Methods: A descriptive correlation study design was used with a convenience sample consisting of 201 middle-aged women recruited from an urban area. SPSS 21.0 was used for a descriptive analysis, t-test, ANOVA, Pearson's correlations and multiple-regression analysis. Results: Quality of life had a significant positive correlation with resilience(r=.53, p<.001) and negative correlation with life stress(r=-.27, p<.001). The significant factors for quality of life were resilience (B=.425, p<.001) marital-status (B=.227, p=.001) and health status (B=-216, p=.001). These factors explained 36.8% of the variance in quality of life. Conclusions: In conclusion, to promote quality of life middle-aged women, there is a need to develop an intervention program to improve resilience.
