Utilization of mineral and chemical admixtures in concrete technology has led to changes in the formulation and mix design in recent decades, which has, in turn, made the concrete stronger and more durable. Lightweight concrete is an excellent solution in terms of decreasing the dead load of the structure, while self-compacting concrete eases the pouring and removes the construction problems. Combining the advantages of lightweight concrete and self-compacting concrete is a new and interesting research topic. Considering its light weight of structure and ease of placement, self-compacting lightweight concrete may be the answer to the increasing construction requirements of slender and more heavily reinforced structural elements. Twenty one laboratory experimental investigations published on the mix proportion, density and mechanical properties of lightweight self-compacting concrete from the last 12 years are analyzed in this study. The collected information is used to investigate the mix proportions including the chemical and mineral admixtures, light weight and normal weight aggregates, fillers, cement and water. Analyzed results are presented in terms of statistical expressions. It is very helpful for future research to choose the proper components with different ratios and curing conditions to attain the desired concrete grade according to the planned application.

Purpose: The purpose of this study was to examine the relationship of psychosocial wellbeing status and self leadership with job satisfaction of fire officers. The effects of these variables on job satisfaction were also examined. Methods: The study design was a descriptive, correlational design. For this study, data were collected from 189 fire officers in B metropolitan city, K and Y cities. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, and multiple regression analysis with SPSS 21.0 program. Results: The results showed that job satisfaction had a significant correlation with psychosocial wellbeing status (r=-.38, p<.001) and self leadership (r=.26, p<.001). Psychosocial wellbeing status had a significant correlation with self leadership(r=-.47, p<.001). Multiple regression analysis for job satisfaction revealed that the most powerful predictor was psychosocial wellbeing status followed by self leadership. Pychosocial wellbeing status, self leadership, age, marital status and current job task career explained 25.0% of the variance in job satisfaction. Conclusion: Findings indicate that various factors are related to the job satisfaction of fire officers. Based on the results of this study, further development and application of programs to improve fire officers' job satisfaction are needed.

This study develops and numerically verifies an innovative seismically resilient bracing system. The proposed self-centering tension-only brace (SC-TOB) is composed of a tensioning system to provide a self-centering response, a frictional device for energy dissipation, and a high-strength steel cable as a bracing element. It is considered to be an improvement over the traditional self-centering braces in terms of lightness, high bearing capacity, load relief, and double-elongation capacity. In this paper, the mechanics of the system are first described. Governing equations deduced from the developed analytical model to predict the behavior of the system are then provided. The results from a finite element validation confirm that the SC-TOB performs as analytically predicted. Key parameters including the activation displacement and load, the self-centering parameter, and equivalent viscous damping are investigated, and their influences on the system behavior are discussed. Finally, a design procedure considering controlled softening behavior is developed and illustrated through a design example.

Purpose: The purpose of this study was to examine the effect of a medication self-management education program on medication awareness, communication with health care provider, medication misuse behavior, and blood pressure in elders with hypertension. Methods: The research design for this study was a non-equivalent control group quasi-experimental design. Participants were 23 elders for the control group, and 26 elders for the experimental group. The experimental group participated in the medication self-management education program which included the following, verbal education, 1:1 consultation, practice in medication self-management, and discussion over 5 sessions. Data were analyzed using the SPSS 18.0 program. Results: There were statistically significant differences between the experimental and control group for medication awareness, medication misuse behavior, and communication with health care providers. However, no significant difference was found between the two groups for blood pressure. Conclusion: The results indicate that the education program is effective in improving medication awareness and communication with health care providers and in decreasing medication misuse behavior. Therefore, it is recommended that this education program be used as an effective intervention for improving medication self-management for elders with hypertension.

In recent years, ubiquitous and pervasive scenarios have emerged as a complex ecosystem where differentiated software/hardware components interoperate wirelessly and seamlessly. The goal is to enable users to continuously access services and contents, and to always get the best out of their current environment and available resources. In such dynamic and flexible scenarios, the need emerges for flexible and general solutions for continuous runtime self-reconfiguration and self-optimization of ubiquitous support software systems. This paper proposes a fully reconfigurable middleware approach that aims at reconfiguring complex software systems made up of heterogeneous off-the-shelf components from both functional and non-functional perspectives. Our middleware can also extend already existing and non-reconfigurable middleware/applications in an easy and flexible way, with no need to re-design them. The proposed design principles have been practically applied to the implementation of a runtime self-reconfigurable middleware called Off-The-Shelf Ready To Go (OTS-RTG), implemented on top of iPOJO. The reported experimental results both exhibit a limited overhead and show the wide applicability of the proposed solution to many application scenarios, including complex, industrial, Enterprise Service Bus-based ones.

Purpose: The purpose of this study was to investigate the level of uncertainty, physiological risk factors, self-efficacy, and self-management among stroke patients and to identify factors influencing their self-management. Methods: A descriptive correlational design was used for this study. A convenience sample of 149 patients with stroke were enrolled at C national university hospital from February to April in 2016. Data were collected using a structured questionnaire and electronic medical record. Collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlations, and multiple regression analysis with the SPSS/WIN 21.0 program. Results: There were significant negative correlations between uncertainty and self-efficacy (r=-.56, p<.001); between uncertainty and self-management (r=-.56, p<.001); and between total cholesterol and self-management (r=-.23, p=.005). There were significant positive correlations between self-efficacy and self-management (r=.78, p<.001); between uncertainty and total cholesterol (r=.24, p=.003). The significant factors influencing self-management were uncertainty and self-efficacy. Theses variables explained 62.7% of the variance in self-management. Conclusion: The results suggest that intervention programs to reduce the level of uncertainty and to increase the level of self-efficacy among patients would improve the self-management of stroke patients.
