Basic LIFE support (BLS) following by Advanced cardiac LIFE support (ACLS) is intended to rescue the patients with acute circulatory or respiratory failure or both. The most important determinant of short and long-term neurologically intact survival is the interval from the onset of the cardiac or respiratory onset to restoration of effective spontaneous functions of these vital activities.It is commonly accepted that every physician, regardless of specialty, should be able to  perform CPR. It must be also emphasized that CPR, almost invariably, necessitates a rapid interventional follow-care with ACLS procedure.Without well-performed basic LIFE support, advanced cardiac LIFE support is of no remark-: able benefit, BLS and ACLS are processes that must be performed step by step and with respect to the patient's condition.

Nowadays, the fundamental role of having a purpose for LIFE in physical and mental health has been confirmed. According to victor frankl, presence of a purpose in LIFE gives LIFE a meaning and increases resilience against pains and traumas. The importance of the purpose in LIFE construct reveals the need for a reliable and valid TOOL to measure it. Crumbaugh and Maholick's purpose in LIFE questionnaire is the first and one of the most applied TOOLs for the assessment of LIFE's purposefulness. The aim of this research is to determine the factor structure of purpose in LIFE questionnaire. The questionnaire was administered on 206 students who were selected through random stratified sampling at Ferdowsi University of Mashhad. Exploratory factor analysis showed that there are two factors "comprehension" and "purpose" and this finding were confirmed by confirmatory factor analysis. Altogether results of this research showed factor validity of the purpose in LIFE questionnaire with a two factor pattern

Background and Objective: Responsiveness is one of the important properties of health-related questionnaires in demonstrating the changes in a patient's clinical conditions before and after therapy. The present study was carried out with the aim of assessing the responsiveness of the Western Ontario Meniscal Evaluation TOOL (WOMET) and determining its minimal clinically important difference in patients undergoing physical therapy interventions after meniscus injuries. Methods: This cross-sectional methodological study was performed on 100 patients aged 18-70 years with meniscus injuries who underwent physical therapy interventions. Patients completed WOMET and Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaires in the first and tenth sessions. The minimum score obtained from the WOMET questionnaire was zero and the maximum was 1600, and the minimum score obtained from the KOOS questionnaire was zero and the maximum was 168. Internal and external responsiveness were the primary outcomes, and effect size tests, ROC curves, and correlation coefficients were used to examine them. The relationship between the WOMET and KOOS questionnaires were considered as secondary outcomes, which were evaluated by calculating the correlation coefficient. Findings: The results of internal responsiveness showed that the standardized response mean for the entire WOMET questionnaire was 0.11 (insignificant) and Cohen's d score for the entire WOMET questionnaire was -1.586 (large). The difference in the mean internal responsiveness between recovered (20%) and unrecovered (80%) patients reached a significant level (p<0.001). This questionnaire had an acceptable external responsiveness; the area under the curve of the ROC curve was greater and equal to 0.7 and the optimal cut-off point was 20.031 (p<0.001). The Pearson correlation coefficient between WOMET and KOOS questionnaires (except the emotions subscale) was moderate to large (0.5-0.8) with p<0.001. Conclusion: The findings of the study showed that the Persian version of the WOMET questionnaire has a high level of responsiveness and is a suitable TOOL for evaluating the quality of LIFE among patients suffering from meniscus injury.

The purpose this research was to examine the validity and reliability of questionnaire on teachers’ work LIFE quality. This research was conducted in the form of descriptive-analytical and cross-sectional method. The statistical population included all 2747 secondary school teachers in Tabriz in 2016 that were selected through cluster random sampling method. The sample size was determined as 340 individuals according to Routes and Error Formula. The measurement TOOL included the Questionnaire of Teachers’ Work LIFE Quality Ilgan et al. (2014). Next, the data were analyzed using Spss20 and Amos24 software. The results showed that the concerned questionnaire had acceptable level of face and content validity (0. 87). In the case of reliability, it was found that the Intra-class Correlation Coefficient was more than 0. 61. Furthermore, the Cronbach's Alpha Coefficient was 0. 97 and Test-Retest Correlation Coefficient was located in the range of 0. 65 to 0. 89. The results of Exploratory Factor Analysis showed that 5 factors could explain about %77 of the total variance. The results of Confirmatory Factor Analysis represented the appropriate fitness of information with the five-component structure (P

2The current research was conducted with the aim of compiling and validating the educational package of the 10th grade religion and LIFE lesson based on Choice Theory. The research method for the stage of designing and compiling the educational package was descriptive-analytical method mixed . The main themes of the training package and the time required for training were taken from written sources such as the model of G schools and internal and external research projects. To validate the package, while using the face validity method, the content validity method was used in a qualitative and quantitative way. It was used with a panel of 14 experts. 14 experts were considered as the statistical population, 10 of them were in the field of psychology, two were in the field of curriculum planning, and two were in the field of education. In addition, two relative coefficients of content validity and content validity index were used. The minimum and maximum relative content validity coefficients for each item of the package were calculated as 1 and 0.71, and the content validity index in most sessions reached the number (0.85) for all goals in the educational protocol. The results revealed that the educational package of the Religion and LIFE lesson based on Choice Theory for 10th grade students have good formal and content validity and has the necessary validity for educational applications and research use.

Selecting TOOL materials, TOOL sizes and determining the cutting parameters presents a great challenge in machining operations especially in high speed machining processes. In this study effect of feed rate which is one of the important machining parameters and TOOL size on TOOL LIFE in high speed machining of Ti-6Al-4V alloy were investigated. Fixed cutting speed of 200 m/min, feed rate of 0.03 and 0.06 mm/tooth together with axial cutting depth of cut 5.0 mm, and radial cutting depth of cut 1.5 mm were employed as the cutting parameters. TiAlN+TiN coated tungsten cemented carbide insert in two different sizes was used during machining operations. Flank wear land measurement was taken by using a TOOLmakers’ microscope and recorded accordingly throughout the machining processes. The results showed during the machining employing both feed rate and using smaller TOOL size chipping occurred on the TOOL nose along with gradual TOOL flank wear. Also by increasing the feed rates utilizing the smaller size of TOOL highly affected TOOL LIFE compared to employing the larger one during the high speed machining operations. Reducing the feed rate by 50 percent increased the TOOL LIFE of smaller TOOL size by 200 percent.
