OBJECTIVES: The purpose of this study was to evaluate the cyclic fatigue, bending resistance, and surface roughness of EdgeEvolve (EdgeEndo) and ProTaper Gold (Dentsply Tulsa Dental Specialties) nickel-titanium (NiTi) rotary files. MATERIALS AND METHODS: The instruments (n = 15/each) were tested for cyclic fatigue in single- (60° curvature, 5-mm radius) and double-curved (coronal curvature 60°, 5-mm radius, and apical curvature of 30° and 2-mm radius) artificial canals. The number of cycles to fracture was calculated. The bending resistance of both files were tested using a universal testing machine where the files were bent until reach 45°. Scanning electron microscopy and x-ray energy-dispersive spectrometric analysis were used for imaging the fractured segments, while the atomic force microscope was used to quantify the surface roughness average (Ra). RESULTS: EdgeEvolve files exhibited higher cyclic fatigue resistance than ProTaper Gold files in single- and double-curved canals (p < 0.05) and both files were more resistant to cyclic fatigue in single-curved canals than double-curved canals (p < 0.05). EdgeEvolve files exhibited significantly more flexibility than did ProTaper Gold files (p < 0.05). Both files had approximately similar Ni and Ti contents (p > 0.05). EdgeEvolve files showed significantly lower Ra values than ProTaper Gold files (p < 0.05). CONCLUSIONS: Within the limitation of this study, EdgeEvolve files exhibited significantly higher cyclic fatigue resistance than ProTaper Gold files in both single- and double-curved canals.

PURPOSE: The purpose of this study was to (1) develop an acceptance commitment therapy (ACT) based recovery enhancement program for inpatients with mental illness and (2) test the effects of the program on patients' psychological flexibility, recovery attitude, and quality of life. METHODS: A mixed methods design was used: a combination of a repeated-measure design with a non-equivalent control group and qualitative data collection. The participants were 41 inpatients with mental illness (experimental group: 20, control group: 21). The ACT based recovery enhancement program was conducted over four sessions for a total of two weeks. Data were collected from December 2018 to January 2019. RESULTS: Study results revealed that the ACT based recovery enhancement program was effective for psychological flexibility (F=150.71, p<.001), recovery attitude (F=60.22, p<.001), and quality of life (F=31.59, p<.001) for inpatients with mental illness. CONCLUSION: The results of this study suggest that the ACT based recovery enhancement program can be used as an effective mental health nursing intervention for psychological flexibility, recovery attitude, and quality of life of inpatients with mental illness.

PURPOSE: This study aimed to use a web-based survey to investigate the correlation between job satisfaction and marital quality and to identify the association of demographics with job satisfaction and marital quality. METHODS: Married nurses (N = 2,296) completed the questionnaires. Correlations and linear regression analyses were carried out. RESULTS: Both marital quality and job satisfaction were relatively low. Additionally, marital quality was positively correlated with job satisfaction. Age, marital status (in years) and average daily hours spent with spouse had positive impact on job satisfaction. Multiple linear regression analyses showed that age, monthly income, average daily hours spent with spouse and marital quality were positively associated with job satisfaction. CONCLUSION: Because of the shifts nurses working, there is little time for nurses to spend with their spouses and family. It is recommended that hospital leaders could provide more flexibility with nurses' shift choices so nurses can arrange their work-life balance better. Other considerations like reducing workload and reducing working hours should be promoted as options. Nurse managers could offer counseling services including strategies to cope with the balance between work and life. This effort could improve job satisfaction and reduce the rate of turnover of nurses.

BACKGROUND AND OBJECTIVES: This study compared two types of skin graft reconstruction for the defect of the radial forearm free flap. SUBJECTS AND METHOD: Ten cases of split-thickness skin graft (STSG) harvested from the thigh were analyzed. Also, ten cases of full-thickness skin graft (FTSG) harvest from the inguinal area applied with vacuum-assisted closure (VAC) system were analyzed. RESULTS: The defect size of the radial forearm was increased more in the STSG group than in the FTSG group (p<0.05). Skin grafts were recovered completely sooner in the FTSG group than in the STSG group although it was not statistically significant (p=0.082). Five complications (pruritus, hypertrophic scar) were found in the donor site in the STSG group (p<0.05). FTSG gave better scores according to the Vancouver Scar Scale in terms of pigmentation, pliability, and height (p<0.05). CONCLUSION: FTSG harvested from the inguinal area with the application of VAC system has many advantages for the defect of the radial forearm free flap although it is usually used for smaller size defects than for STSGs.

OBJECTIVE: The aim of this study is to perform validity and reliability examination of the Turkish form of Acceptance and Action Diabetes Questionnaire, and to investigate whether this scale is a measurement tool for evaluation of psychological flexibility levels in a sample of patients with diabetes in Turkey. METHODS: This study was conducted with 105 patients. Turkish forms of the Beck Depression Inventory (BDI), Problem Areas in Diabetes Questionnaire (PAID), State-Trait Anxiety Inventory (STAI-I and STAI-II), Audit of Diabetes-Dependent Quality of Life (ADDQoL) and Turkish form of Acceptance and Action Diabetes Questionnaire (TAADQ) were applied. SPSS 20.0 and AMOS was used in statistical analysis. RESULTS: 56.12% of the patients were female and the mean of age was 54 (SD=±9.9) years. The mean duration of education was found 7.65 (SD=3.97) years. 74.8% of the patients most of whom (83.3%, n=85) had diabetes mellitus and the mean glycemic control calculated with HbA1c was 8.02±1.91. According to the final fit indices, we found that the revised and corrected 9-item model was superior over the previous model. Cronbach Alpha coefficient of TAADQ was found as 0.836. CONCLUSION: TAADQ is a valid and reliable assessment tool in Turkish population. So TAADQ will be a powerfull tool in assessing psychological flexibility in diabetes patients.

BACKGROUND: Ice cooling vests can cause tissue damage and have no flexibility. Therefore, these two undesirable properties of ice cooling vest were optimized, and the present study was aimed to compare the impact of the optimized ice cooling vest and a commercial paraffin cooling vest on physiological and perceptual strain under controlled conditions. METHODS: For optimizing, hydrogel was used to increase the flexibility and a layer of the ethylene vinyl acetate foam was placed into the inside layer of packs to prevent tissue damage. Then, 15 men with an optimized ice cooling vest, with a commercial paraffin cooling vest, and without a cooling vest performed tests including exercise on a treadmill (speed of 2.8 km/hr and slope of %0) under hot (40℃) and dry (40 %) condition for 60 min. The physiological strain index and skin temperature were measured every 5 and 15 minutes, respectively. The heat strain score index and perceptual strain index were also assessed every 15 minutes. RESULTS: The mean values of the physiological and perceptual indices differed significantly between exercise with and without cooling vests (P < 0.05). However, the difference of the mean values of the indices except the value of the skin temperature during the exercises with the commercial paraffin cooling vest and the optimized ice cooling vest was not significant (P > 0.05). CONCLUSIONS: The optimized ice cooling vest was as effective as the commercial paraffin cooling vest to control the thermal strain. However, ice has a greater latent heat and less production cost.

PURPOSE: There are several commercially approved stent grafts in Korea for the treatment of abdominal aortic aneurysms (AAAs). Each device has its advantages and disadvantages based on the patient’s anatomy and the clinical situation. The Zenith device allows accurate and precise endograft placement, whereas the Endurant device has improved flexibility and trackability. We reviewed 5 cases in which a combination of the Zenith main body and the Endurant iliac limb was used. MATERIALS AND METHODS: From January 2010 to February 2015, 90 patients with AAA underwent endovascular aneurysm repair (EVAR) using the Zenith body at Daegu Catholic University Hospital. Among them, 5 patients who underwent EVAR with the Zenith body and Endurant iliac limb were included in this study. RESULTS: The mean age of the patients was 74.20±3.35 years. All patients were men. The main reason for use of the Endurant iliac limb was aortoiliac angulation. Type III endoleak, stent migration, and stent kinking were not noted. Comparing 85 patients who received a Zenith endograft with 5 patients who received the hybrid endograft, there were no statistical differences in clinical characteristics, intraoperative details and post procedural complications. The mean admission duration was 19.00±13.60 days, and the mean follow-up duration was 1,018.11±925.34 days. In the hybrid endograft group, there was no mortality during the follow-up duration. CONCLUSION: Although the material, radial force, diameter, and length of the overlap zone differ between the two devices, EVAR with the hybrid endograft is safe and effective.

PURPOSE: Relaxin (RLX) is a transforming growth factor-β1 (TGF-β1) antagonist that is believed to function as a potent collagen re-arranger and a major suppressor of extracellular matrix components. Adenoviruses (Ads) are accepted vectors for cancer gene therapy. However, repeated treatments of Ad are limited by short-term biological activity in vivo. The efficacy of sustained RLX expression to scar remodeling was assessed using an injectable alginate gel-matrix system. MATERIALS AND METHODS: Pig scar tissue was treated with relaxin-expressing Ad loaded in alginate gel (gel/Ad-RLX). Surface areas, color, and pliability of scars were compared, and various factors influencing scar formation and collagen arrangement were analyzed. RESULTS: Gel/Ad-RLX decreased scar size, color index, and pliability. Immunohistochemistry showed decreased levels of major extracellular matrix proteins in the gel/Ad-RLX-treated group. Furthermore, treatment with gel/Ad-RLX reduced expression of tissue inhibitor of metalloproteinase-1 and alpha-smooth muscle actin and markedly increased expression of matrix metalloproteinase-1 in pig scar tissues. Gel/Ad-RLX also significantly downregulated TGF-β1 and upregulated TGF-β3 mRNAs in pig scar tissues. CONCLUSION: These results support a prominent role for RLX in scar remodeling and suggest that gel/Ad-RLX may have therapeutic effects on scar formation.
