Main objective of this study is to assess relationship between self-esteem and psychological empowerment of Ground Force commanders of the Islamic Republic of Iran Army. By purpose, it is practical and by method it is classified as correlative. Data collected through a questionnaire with Likert response spectrum and the questions according to the variables in the theory of standard questionnaires (Smith and Spreitzer) was extracted. The population of this research includes the commanders of the Iranian army units who were engaged in the task. 384 questionnaires were distributed and used. Pearson correlation test and SPSS 19 software was used for data analysis. The results show that there is a significant positive relationship between the two variables, namely, self-esteem and psychological empowerment of Ground Force commanders of the Islamic Republic of Iran Army.

The role of innovative, experienced, and quality employees to perform assigned missions has been incredibly important. Field studies show that there have been some concerns regarding the possible loss of specialists due to early job abandoning in air defense Khatam- ol - anbya (pbuh) headquarters. Hence, the aim of this study is to determine and measure the effectiveness of factors (individual, organizational and environmental) which affect personnel to decide to quit their job. This is a descriptive type of research with mixed approach. The population used in this study is 2100 members of air defense headquarters.Information was gathered through questionnaire and interviews with experts and some of those who left air defense headquarters. After reliability of questionnaire was confirmed by experts, they were sent to 100 members of air defense headquarters who were chosen through Cochran formula in a way that include all three different officers, noncommissioned officers and civil. Validity of questionnaire was confirmed through Cronbach’s alpha test and split-half method.

Today, education must develop in people capability so that they can keep pace with rapid social changes. To achieve these goals requires diagnosing the talents and abilities of individual students based on ongoing research and investigations according to methodology and scientific standards and to help each student according to his resources and capabilities on the one hand and needs of changing society on the other hand. The purpose of this study is to evaluate advisor services effectiveness in reducing behavioral and academic problems of students in Military University of Imam Ali (AS). Data collection is questionnaire which includes 22 items and the validity and reliability test of questions using a five-item Likert has been confirmed.They have been performed in the Military University of Imam Ali(AS) individually. Statistical methods for data description is descriptive statistics and for data analysis T test independent groups, Pearson's correlation test, Mean test and one-way ANOVA were used.The results indicate that the overall effectiveness are different from the perspective of students and faculty advisors.The rate of overall effectiveness of advisors are also different from the view point of freshmen, sophomore and junior students.

Strong dependence of any organization on the quality of staff employed (quality staff) caused managers and authorities to look for selection and acceptance of the best. This research initiated the work with this question "what are the best practices for recruitment of the quality personnel in the Islamic Republic of Iran Army?" Identifying characteristics of quality manpower and factors affecting the quality of recruitment in the Islamic Republic of Iran Army were determined as the objectives of this research. Naturally, the type of research is qualitative and analytical-descriptive research method by selecting a 20 member community expertise was sought. Data collection for the survey was questionnaire distributed among the two study areas. The data obtained from this study using the Delphi consensus and expert opinion and the results obtained which are sum opinion of at least 95% research experts, has been stated as research outcome. The steps of the scientific method of research starts with initial questions and continues with exploratory studies, conceptual design of the research, making the research model, observation, information analysis and ultimately research conclusion. Firstly, in this research project, the characteristics of qualitative personnel explored from all sources and interviews through questionnaires and interviews with experts, and then the priority ranking of each feature were determined in five categories. Determining the courses of action to recruit different branch categories of a family of twenty-eight branches, four strategies R1, R2, R3 R4 were defined and prioritized strategies courses of action I and II to recruit were found.

Transferring data in remote sensing systems and their coding methods are one of the most practical and advanced sciences in the world. Scientists try to invent new methods for this purpose. Telemetry channel coding is a method to process transferring data from source to destination, through which separated message can be generatedin a way that can be easily and simply distinguished from each other. Coding reduces error probability and increases channel efficiency. Although introduced channel coding themes is not the only code used in space missions but investigating the best coding schemes by CCSDS standard is the aim of this paper. We first would explain cross convolutional coding with ½ symbol rate, punctured convolutional coding and also Reed Solomon (RS) Code that have many advantages in bandwidth and error recognition. At the end, turbo code and also code block synchronization will be introduced.
