  • Purpose: A network meta-analysis was conducted to assess the comparative effects and ranks of repositioning for pressure ulcer prevention in adults. Methods: A network meta-analysis was performed in a frequency method, using the "netmeta" package of R software version 4.1. The effects of repositioning intervention were confirmed by the odds ratio. The comparative ranking of the repositioning effects was confirmed using the cumulative probability (P-score). Results: Seven intervention studies were included in this study. Based on the P-score, the use of the repositioning system was ranked as the most effective among all interventions (P-score 78.7%). Next was 3~4-hour repositioning combined with memory foam mattress use (P-score 77.2%), use of wearable sensor (P-Score 61.4%), 2-hour repositioning combined with memory foam mattress use (P-score 59.1%), 2-hour repositioning combined with powered air pressure redistribution mattress use (P-score 18.0%), and 4-hour repositioning combined with powered air pressure redistribution mattress use (P-score 18.0%). Conclusion: This study provides information on the relative comparative value of various repositioning interventions to prevent pressure ulcers using network meta-analysis. This is expected to be useful for nurses' decision-making when applying repositioning interventions in clinical practice

  • The purpose of this research is to develop a full-spectral fatigue analysis program, based on rigid-body ship motion analysis, in order to perform a full-spectral fatigue analysis that considers hydroelasticity effects. To gain credibility, fatigue analysis results of two ship types, performed by the developed program, were compared with those of a classification society, and it was found that both are identical. Full-spectral fatigue analysis considering hydroelasticity effects would be developed in further studies by including flexible-body ship motion analysis results and by supplementing the developed program with a wide-band fatigue damage model.

  • The purpose of this paper is to examine the effects of interior landscape that influence preference at a department store in order to answer the research question; What are the effective factors of interior landscape that affect preference at a department store. After review of the effect of interior landscape, and the interior landscape at a department store, we constructed a literature framework and have formulated the hypothesis of this research. We have analyzed the data which surveyed 108 visitors about the interior landscape in a department store, using factor analysis, Pearson's correlation analysis, and the multiple linear regression method. We found that; 1) eleven variables can be selected for the effects of interior landscape at department store: accessibility, image, stay, distinction, comfort, complexity, cleanness, mystery, purification of atmosphere, noise and harmony. Among the 11 independent variables used to study the effect of interior landscape at a department store, the image and purification of atmosphere highly affect preference. 2) These 11 variables are grouped by factor analysis as effects of amenity, attractiveness and identity. 3) As a result of multiple regression analysis, independent variables influencing preference were proved statistically significant at one percent level. 4) Regarding their relative contribution of interior landscape effect at a department store, the effects of amenity was the most important and it showed a level of importance 1.4 times higher than the effect of identity, and 1.25 times higher than the effect of attractiveness. The research results suggest the need for guidelines for the creation of interior landscape at department stores. The approach and analysis method adopted by this research is highly useful for the evaluation of interior landscape criteria at a department store. It is recommended that more practical study on factors affecting user's preference be performed in the future.

  • Objectives: Obesity is a chronic metabolic disease that negatively affects quality of life and health. It is associated with various disease and its prevalence is on the rise. Although various treatments for obesity are used, they have several adverse effects. Pharmacoacupuncture is a widely used method for treating various diseases and has the advantage of having fewer adverse effects. This systematic review and meta-analysis evaluate the efficacy of pharmacoacupuncture in treating obesity. Methods: Eight electronic databases were searched from their inception to August 2023. Only randomized controlled trials were included in this review. Intervention groups included pharmacoacupuncture. Control groups had no limitation. The primary outcome was body mass index (BMI), and the secondary outcomes were body weight (BW), waist circumference (WC), and adverse effects. Continuous outcome data were presented as mean differences (MD) with 95% confidence intervals (CI). Results: Four randomized controlled trials (RCTs) involving 139 participants were included in this systematic review and meta-analysis. Results revealed that BMI ((MD)=-0.98, 95% CI -1.84 to -0.11, Z=2.22, P=0.03, I2=0%), WC (MD=-4.29, 95% CI -7.51 to -1.08, Z=2.62, P=0.009, I2=38%) were significantly improved in the intervention groups compared to control groups. Adverse effects were reported in two studies. Conclusions: This systematic review and meta-analysis suggests that pharmacoacupuncture is an effective and safe therapy for simple obesity. Further detailed studies should be conducted on effects of pharmacoacupuncture for obesity to increase reliability.

  • Cichorium intybus (Compositae) has been used for fevers, dyspepsia, headache and jaundice, as a demulcent. Also, it has relaxation effects and relief effects against coffee and teas, and is widely used as food. We investigated anti-lipid peroxidative effects and liver protective activity on $CCl_4$ induced lipid peroxidation and hepatotoxicity in rats. MeOH Ex. enhanced the inhibition of anti-lipid peroxidative effects in liver lipid. In chemical parameters obtained from serum analysis, MeOH Ex. revealed significant decrease on hepatotoxicity. The results were as follows; 1. The inhibitory effects of lipid peroxidation were shown in accordance with the increase of samples' concentration level. 2. In chemical parameters obtained from serum analysis, the activities of GOT, GPT, AlP were restored to near the normal level. The contents of cholesterol and BUN showed inhibitory effects with valence. 3. The weights of liver and spleen were not able to restore to the normal level. But on a general level, they were reduced more than the control group.

  • This study aimed to verify the mediating effects of cognitive function and social support and to establish a structural relationship between child maltreatment and resilience in school-age children (n=357) taken in by child protection service. In the first model (linear arrangement), each protective factor mediates independently between maltreatment and resilience; in the second model (arrangement in due order), cognitive function has mediating effects prior to social support. Analysis of data included descriptive statistics, Cronbach's a, confirmatory factor analysis, and structural equation modeling. Results of the first model showed indirect effects of cognitive function and social support. Results of the second model significantly affirmed that the mediators, cognitive function and social support, diminish negative effects of maltreatment by bolstering resilience.
