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

Purpose: The purpose of this study was to investigate the effect of auricular acupressure on insomnia. Methods: Forty-four adults with insomnia for >1 month were recruited and randomly assigned to either the experimental or control group. In the experimental group, acupressure stickers were attached to the areas of Pineal Gland (TG1), Aggressivity point (LO2), Point Zero (HX1), and Occiput (AT3) for 1 week. Sleep hygiene education materials were provided to the control group, but acupressure was not provided. The collected data were analyzed using the SPSS ver. 26 program. Results: As a result of controlling for the severity of insomnia (F=5.40, p=.025) and headache (F=4.60, p=.038), which showed a significant difference in the homogeneity test as covariates, the Pittsburgh Sleep Quality Index score in the experimental group decreased compared to that in the control group . Conclusion: The result of this study showed that auricular acupressure was helpful in improving insomnia.

Purpose: The aim of this study was to examine the effects of sling exercise on fall risk score, ankle dorsiflexion and balance in community-dwelling elderly women. Method: A 6-week prospective study was conducted to examine the effects of sling exercise. Participants were required to attend their assigned exercise classes three times a week for 6 weeks. Result: After the 6 week study period, PPA fall-risk scores were reduced by 0.90 for the exercise group, which was a significant change (p<.001). Dorsiflexion strength increased significantly (p<.01) by 1.56 kg after the sling exercise. There was a 2.0 cm-increase (p<.05) in FRT and 0.38 second-improvement (p<.01) in TUGT. A 7.88 second-increase in One-leg standing with Eyes Open and a 3.12 second-increase in One-leg standing with Eyes Closed were reported during the 6-week intervention period. Conclusion: The 6-week sling exercise reduced falls risk score significantly (p<=.001) in community-dwelling elderly women by improving fall risk related factors such as reaction time, balance and strength.

Purpose: The purpose of this study was to examine the effects of a Tai Chi exercise program on physical function and physiological variables in patients with degenerative arthritis. Methods: The study utilized a nonequivalent control group with pretest-posttest design. Data collection was done with the elders from two welfare institutions in C-city between July I and September 22, 2007. The participants were assigned either to an experimental group (n=24) or to a control group (n=22). The experimental group participated in Tai Chi exercise for 60 minutes per session, twice a week for 12 weeks and the control group received the education about arthritis for 3 weeks. Results: Except for $VO_2max$, weight, and body fat rate, the elders in the experimental group showed significant improvement in physical function (grip strength, flexibility, balance), and physiological variables (BP) compared to the control group. Conclusion: The results suggest that Tai Chi exercise would partially improve physical function, and physiological variables. Further studies are needed to determine the effects on physical fitness and physiological variables after Tai Chi exercise in this population.

Purpose: This study aimed to verify the effects of a swallowing training program on swallowing function and depression for nursing home residents with dysphagia after stroke. Methods: This is a quasi-experimental study with non-equivalent control group pre-post test design. The program (oro-facial muscle strengthening exercises, swallowing exercises, expiratory muscle strengthening exercises, and brain stimulation exercises) applied to the experimental group three times per week for eight weeks, 40-45 minutes for each intervention. The final data from 42 people (21 experimental and 21 control) were analyzed by SPSS/WIN 25.0 using descriptive statistics. 𝜒² test, t-test, Wilcoxon rank sum test, and Friedman test. Results: The experimental group was significantly improved than control group in oro-facial muscle strength, swallowing symptoms (Z=-2.22, p=.026), and oral intake function level (Z=-2.00, p=.046). However, there was no significant difference between two groups in depression. Conclusion: This study is meaningful in that it reorganized and mediated a swallowing training program as a safe, non-invasive exercise that nurses can implement in a nursing facility with limited medical personnel and it could be easily followed by older adults.

Objectives: To compared the effect of different levels of moisture of root canal on the sealing ability after filling with four different types of sealer. Materials and Methods: Single-rooted teeth (n = 90) instrumented to and apical size of 0.06 / 45 were randomly assigned to 12 experimental groups (n = 7 per group), positive/negative control groups (n = 3 per group). The teeth of the experimental groups (a. DRY; b. PAPER POINT DRY; c. WET) were obturated with sealer (Group 1-3: Sealapex; Group 4-6: AH plus; Group 7-9: Tubuli-seal; Group 10-12: EndoRez) and warm vertical compaction method. After 7 days in $37^{\circ}C$, 100% humidity, the coronal-to-apical microleakage was evaluated quantitatively using a glucose leakage model. The leaked glucose concentration was measured with spectrophotometer at 1, 3, 7, 14, 21, and 30 days. Data were recorded ad mmol/L and statistically analysed with the two-way ANOVA and Duncan test (p = 0.05). Results: Throughout the experimental period Tubuli-seal/WET (Group 9) showed the highest mean cumulative glucose penetration (178.75 mmol/L), whereas AH plus/DRY (Group 4) had the least (20.78 mmol/L). Conclusions: The results of this study demonstrated that the moisture condition of root canals at the time of obturation and the type of sealer that was used had a significant effect on leakage and sealing ability. Thus drying procedure according to sealer types is a critical step and should not be missed in endodontic treatment.

Purpose: The aim of this study was to assess the physical properties of a novel resin-based endodontic sealer, Any-Seal, in comparison with AH Plus Jet. Materials and Methods: Flow, radiopacity and compressive strength were examined according to ISO 6876/2001. For flow test, 0.05 mL of sealer was placed between glass plate and 100 g weight were applied. Ten minutes after mixing the sealers, the load was removed and the diameters of the compressed sealer discs were measured. For radiopacity, 10 mm diameter and 1 mm thickness sample were fabricated and took radiograph with an aluminum step-wedge and analyzed using imaging program. For compressive strength test, $4mm{\times}6mm$ cylindrical specimen was fabricated and tested after 24 hours and 1 week using Universal testing machine. Results: Both tested sealers were consistent with ISO 6876/2001 in the flow and radiopacity test. The flow values of both sealers were not significantly different (P > 0.05). AH Plus Jet had significantly higher radiopacity (P < 0.05). AH Plus Jet showed higher compressive strength at both time intervals (P < 0.05). Conclusion: Any-Seal showed low compressive strength until after 1 week, so its physical and biological aspect should be evaluated more before clinical use.

Purpose: The purpose of this study was to assess nurses' educational needs for developing advanced nursing education program for musculoskeletal care. Methods: The participants consisted of 272 clinical nurses who had experience of taking care of patients with musculoskeletal problems. A structured questionnaire with 28 items was used to assess educational needs and priority perceived by clinical nurses. Collected data were analyzed using SPSSWIN V.18.0 program for descriptive statistics. This survey was conducted in accordance with standard ethical guidelines for all research involving human participants. Results: While the majority (93.4%) perceived needs for advanced education program, about half of the participants (48.5%) reported no educational experience about musculoskeletal care. The clinical nurses perceived important for 23 out of 28 areas to be included in advanced nursing education. Especially, the areas of pain management, surgical care, and medication were perceived high priority for education program in caring musculoskeletal patients. Conclusion: The study findings showed that most nurses perceived the need for advanced nursing education program in musculoskeletal care, and the areas with higher priority as perceived by nurses should be reflected in the program.
