Buckling-restrained braces (BRBs) have excellent hysteretic behavior while buckling-restrained braced frames (BRBFs) are susceptible to residual lateral deformations. To address this drawback, a novel self-centering (SC) BRB with Basalt fiber reinforced polymer (BFRP) composite tendons is presented in this work. The configuration and mechanics of proposed BFRP-SC-BRBs are first discussed. Then an 1840-mm-long BFRP-SC-BRB specimen is fabricated and tested to verify its hysteric and self-centering performance. The tested specimen has an expected flag-shaped hysteresis character, showing a distinct self-centering tendency. During the test, the residual deformation of the specimen is only about 0.6 mm. The gap between anchorage plates and welding ends of bracing tubes performs as expected with the maximum opening value 6 mm when brace is in compression. The OpenSEES software is employed to conduct numerical analysis. Experiment results are used to validate the modeling methodology. Then the proposed numerical model is used to evaluate the influence of initial prestress, tendon diameter and core plate thickness on the performance of BFRP-SC-BRBs. Results show that both the increase of initial prestress and tendon diameters can obviously improve the self-centering effect of BFRP-SC-BRBs. With the increase of core plate thickness, the energy dissipation is improved while the residual deformation is generated when the core plate strength exceeds initial prestress force.

Purpose: This study was to examine the impact of acculturation and social support on the mental health among Korean-American registered nurses. Methods: Data were collected with a convenience sample of 203 Korean-American registered nurses living in New York state and New Jersey state from 8th May to 25th August in 2012. The structured questionnaires measured the degree of acculturation, social support, and mental health. Data analysis was conducted using t-test, ANOVA, Pearson correlation efficient, and Stepwise multiple regression. Results: Lower level of integration and higher level of marginalization were associated with the lower mental health. Social support was also positively related to mental health and had mediating effect on the relationship between acculturation and mental health. The five variables, including participants' educational background, work shift, integration, marginalization, and social support were significant to predict the level of mental health among Korean-American registered nurses, accounting for 41% of the variability. Conclusion: The results imply that higher level of social support and strong identity of both home and host culture will enable Korean-American registered nurses to maintain sound mental health.

Purpose: The objective of this study was to define the predictors of health related quality of life(HRQoL) of women caregivers of the demented elderly patients. Methods: The subjects of this study were 140 pairs of patients with dementia and their caregivers. The characteristics of dementia patients and caregivers, Barthel index and SF-36 were measured in this study. T-test, ANOVA, Pearson correlation coefficient, and stepwise multiple regression were used for data analysis. Results: The health related quality of life(HRQoL) score of women caregivers was $288.35{\pm}66.10$ for norm based scoring. HRQoL of women caregivers was correlated with patients' ADL, severity of dementia, caregivers' age, burden, and family support. The major factors that affected the physical components of women caregivers of patients with dementia was the age of the caregiver, burden, and ADL which explained 36.0% of HRQoL. The main predictors of women caregivers' emotional state was the caregiver's burden. Conclusion: Patients' support systems must be implemented to improve the physical HRQoL of caregivers. A caregivers' burden relief program needs to be prepared to increase their emotional HRQoL and further studies and efforts will be needed to evaluate those effects.

Background: Cigarette smoking is as the leading cause of cancer mortality and other chronic diseases in males worldwide. The prevalence of cigarette smoking is different across and within countries by age, education level, occupation, and so on. This study aimed to determine the prevalence of cigarette smoking and its relationship with individuals' demographic factors and BMI in adolescent men living in Tehran, Iran. Materials and Methods: This study involved secondary analysis of the 'Urban Health Equity Assessment and Response Tool-2' survey conducted in Tehran, Iran, among men aged 20+, 2011-2012. Using a multistage sampling method, 45,990 men were included in the study. The cigarette smoking status, BMI and demographic factors measured through a self-administered questionnaire. Chi-square, t-test, and logistic regression model were used to examine the relationships between the independents variables and cigarette smoking behavior, using SPSS software version 21. Results: In the total of 45,990 men, the overall prevalence of cigarette smoking was 14.6% (CI 95%: 14.29-14.94). Age (OR=0.96; CI 95%:0.94-0.98), house ownership (OR=0.68; CI 95%: 0.64-0.72), job status (OR=0.60; CI 95%: 0.46-0.86), marital status (OR=0.42; CI 95%: 0.39-0.47) and educational levels (OR=0.50; CI95%: 0.45-0.54) were associated with the prevalence of cigarette smoking. However, associations with BMI, family size, residency years, and district were not statistically significant. Conclusions: Given the relatively high prevalence of cigarette smoking in the study population, policy interventions are required to address this major public health issue, with a focus on the population demographic influences.

Background: The aim of this study was to assess the predictive role of religious coping in quality of life of breast cancer patients. Materials and Methods: This multi-center cross-sectional study was conducted in Tehran, Iran, from October 2014 to May 2015. A total of 224 women with breast cancer completed measures of socio-demographic information, religious coping (brief RCOPE), and quality of life (FACT-B). Data were analyzed using descriptive statistics and the t-test, ANOVA, and linear regression analysis. Results: The mean age was 47.1 (SD=9.07) years and the majority were married (81.3%). The mean score for positive religious coping was 22.98 (SD=4.09) while it was 10.13 (SD=3.90) for negative religious coping. Multiple linear regression showed positive and negative religious coping as predictor variables explained a significant amount of variance in overall QOL score ($R^2=.22$, P=.001) after controlling for socio-demographic, and clinical variables. Positive religious coping was associated with improved QOL (${\beta}=0.29$; p=0.001). In contrast, negative religious coping was significantly associated with worse QOL (${\beta}=-0.26$; p=0.005). Conclusions: The results indicated the used types of religious coping strategies are related to better or poorer QOL and highlight the importance of religious support in breast cancer care.

Aim: In this study we aimed to investigate the healthy life-style behaviour of Turkish women and establish influencing features. Methods: This descriptive study performed by a questionnaire method was conducted in a primary health care centre, in an urban region in Kayseri, Turkey. Every midwife region belonging to the health care centre was accepted as a cluster, and a sample of 450 women between ages 18-64, was gathered from 9 midwife regions. The Health Promotion Life-style Profile (HPLP) was applied to evaluated the healthy lifestyle behaviour of 421 women that could be reached. T test, Tukey HSD with ANOVA, and chi square tests were used for analysis. Results: The mean total HPLP was $126.8{\pm}19.2$ (interpersonal support subscale, $74.3{\pm}14.1$; nutrition subscale, $73.6{\pm}12.6$; self-actualisation subscale, $70.6{\pm}11.9$; stress management subscale, $63.4{\pm}13.0$; health responsibility subscale, $61.2{\pm}13.2$; and exercise subscale, $47.1{\pm}15.0$). There was no statistically significant variation when evaluated for age, marital state, family type, economic status, and perception of self-health, smoking, and BMI. HPLP was high in people with an education of primary school and lower in university graduates, in people who lived mostly in the city centre and in individuals with chronic diseases. In conclusion, it was established that the health promoting behaviour in Turkish women is, in general, at a medium level, and women should be enlightened in order to develop and increase the habit of health preservation and promotion.

Background: Data regarding childhood and adolescent non Hodgkin lymphomas in Iran are limited. The aim of this study was to assess the epidemiological and histomorphological features and survival of affected patients in our center. Materials and Methods: The clinicopathologic features and outcome of 44 children and adolescents with non Hodgkin lymphoma diagnosed during 2004-2012, were investigated retrospectively. The influence of potential prognostic parameters in overall survival was investigated by log-rank test and Cox regression analysis. Results: The mean age at presentation was $13.8{\pm}6.16$ years with a male predilection (M: F=3:1). Malignant lymphoma, not otherwise specified, diffuse large cell lymphoma and Burkitt lymphoma were the three most common histological types observed. The tumors were 36.4% intermediate grade, 27.3% high grade and 34.1% belonged to the malignant lymphoma not otherwise specified group. Immunohistochemistry findings were available in 39 cases. Out of these cases 33 (84.6%) had B cell lineage, 4 (10.25%) T cell lineage and 2 (5.12%) of the cases belonged to miscellaneous group. 3 year and 5 year survivals were 48% and 30% respectively and median survival was 36 months (95%CI=21.7-50.3 months). Overall survival in patients with high grade tumors was 19.5 months, in the intermediate group,79 months, and for malignant lymphomas not otherwise specified it was 33.6 months (p value=0.000). Conclusions: The survival rate for children and adolescents with non Hodgkin lymphomas at our center during 2004-2012 was at a low level.

The main objective of this research is to find out whether there exist any user interface factors that influence service information management professionals(SIMP)'s business activities on the web. The result of this study shows that there exists a significant level of difference between two groups of office Professionals： SIMP and general office management professionals on user interface factors. We analyzed the past and current research results and focused on four major evaluation categories： (1) web design, (2) structure, (3) navigation, and (4) interaction and identified 26 evaluation items in those categories. The study has been initiated by an intuition that there might be a significant difference in sets of user interface factors that influence SIMP and general office professionals. From the list of Best 100 Web Sites the best 30 information-providing web sites and the best 30 service-providing web sites were carefully chosen by a panel of 10 members for each group. To evaluate 60 web sites, another panel was formed by 30 professionals from each group, and they conducted evaluation in their own work settings. Reliability analysis on user interface factors and T-test to find out any influencing factors on SIMP were performed. As a result of this study, we have recognized that clarity, formation, consciseness, economics, and robustness are the most influencing user interface factors for web designers to concern when they develop web sites for SIMP. The study result can be improved by enhancing reliability of choosing target web sites In investigate and panel members. Also, in the future study it is recommended to investigate influencing factors for office professionals in terms of. age, sex, experience, academic background, etc.
