Abstract: Introduction: Appendicitis is a common urgent surgical operation. Since early diagnosis and treatment of appendicitis is necessary and also some disease mimic its clinical manifestation and rate of negative appendectomy was high (15-30%), so surgeons were trying to increase the accuracy of diagnosis of appendicitis by using laboratory facilities. The main aim of this study were to investigation of Sensitivity and Specificity CRP in the diagnosis of acute appendicitis and compare it with routine laboratory tests such as leukocyte count and neutrophil count.Material and Methods: In this descriptive - analytical study, blood samples of 191 patients with diagnosis of acute appendicitis that underwent appendectomy at the Besat hospital, were used to measuring of CRP. The surgical specimens were reviewed by pathologists and pathologic findings were considered as gold standard. Then by using of the results of pathology tests, sensitivity, specificity and positive and negative predictive value of CRP, WBC and neutrophils were measured. Data were analysed by SPSS-14 software and t test and chi square test.Results: 74/3% of patients were male and 25/7% female and the mean age was 26 ± 3/4 years. The most common symptom, sign and pathologic stage of patients were loss of appetite (95/2%), local tenderness (95/8%) and Acute suppurative (64/9%). 08/13% of patients had normal appendectomies that consist of 35% of women and 6% of men appendectomy. The sensitivity and specificity of CRP, WBC and neutrophils respectively were: 98/1%, 61/5%, 84/8%, 50%, 93/3% and 19.2%.Conclusion: According to the results, the CRP test at diagnosis and in finding of negative appendectomy has high value. But wasn't reliable as an exclusive test. Therefore, the use of CRP as a paraclinical criterion along with other criteria of Alvarado scoring system can be very useful in diagnosis of appendicitis.
Asymptomatic Bacteriuria in Pregnant Women

Urology Journal , 2007,
Abstract: Introduction: The aim of this study was to evaluate the frequency of bacteriuria in pregnant women referred to the medical centers of Tabriz, Iran, for prenatal care. Materials and Methods: A total of 1100 healthy pregnant women who were referred to 50 medical centers in Tabriz for a regular prenatal care were evaluated for bacteriuria. Results: The frequency of asymptomatic bacteriuria was 6.1%. Maternal age was lower in the women with a positive urine culture (P = .02). Asymptomatic bacteriuria had no relationship with gestational age, parity, level of education, and body mass index. Conclusion: We found a relatively high rate of bacteriuria in our cohort of asymptomatic pregnant subjects, especially the younger ones. For prevention from the complications of the asymptomatic bacteriuria in pregnant women, such as pyelonephritis, hypertension, preeclampsia, low birth weight, prematurity, septicemia, and even maternal and neonatal death, it is recommended to perform urine culture as a routine evaluation during the pregnancy.
Directly Specifying the Power Semicircle Distribution

Abstract: A new proof for a newly proved conjecture of Soltani and Roozegar (2012) is provided; our proof does not make any use of the Stieltjes transform unlike the proof of Roozegar and Soltani (2013), and the distribution of power semicircle has been directly specified, contrary to the authors' claim in (Roozegar and Soltani 2013).
A Novel Extension of Randomly Weighted Average
Hazhir Homei
Statistics , 2013,
Abstract: We study a well-known problem concerning a random variable $Z$ uniformly distributed between two independent random variables. A new extension has been introduced for this problem and fairly large classes of randomly weighted average distributions are identified by their generalized Stieltjes transforms. In this article we employ the Schwartz distribution theory for finding distributions of this extension; we also study some of their properties.
Uniform Random Sample and Symmetric Beta Distribution

Abstract: N.L. Johnson and S. Kotz introduced in 1990 an interesting family of symmetric distributions which is based on randomly weighted average from uniform random samples. The only example that could be addressed to their work is the so-called "uniformly randomly modified tin" distribution from which two random samples have been computed. In this paper, we generalize a subfamily of their symmetric distributions and identify a concrete instance of this generalized subfamily. That instance turns out to belong to the family of Johnson and Kotz, which had not seemingly received proper attention in the literature.
Another Generalization of Unimodality

Abstract: A general characterization for \alpha-unimodal distributions was provided by Alamatsaz (1985) who later introduced a multivariate extension of them (Alamatsaz 1993). Here, by solving the related equations, another generalization for unimodality is presented. As a result of this generalization, a simpler proof of a conjecture, as well as a characterization for generalized arcsin distributions and some generalizations of the author's earlier works, have been obtained. Last, but not the least, it is shown that some elementary methods can be more powerful than some more advanced techniques.
An empirical study on measuring the impact of personality type on employee capabilities

Management Science Letters , 2011,
Abstract: Personality is a stable set of characteristics and tendencies, which specifies similarities, and differences of people' psychological behavior. Personality is normally a permanent behavior through time and may not be comprehended easily or recognized as immediate or direct situations due to some environmental and social stresses. In this paper, we study the relationship between employees' personality and ability types. The paper identifies that there are some relationships between employees' personality type and their ability. There is also a relationship between introvert, extrovert, sensitive, emotive, thoughtful, considerate and judging personality type and employees' ability.
On the Analysis of PLC Programs: Software Quality and Code Dynamics  [PDF]

Intelligent Control and Automation (ICA) , 2015, DOI: 10.4236/ica.2015.61007
Abstract: As a result of sudden failure in the Programmable Logic Control (PLC) controlled process, the need of diagnosis arises. Diagnosis problem plays an important role to monitor failures in PLC, used to control the whole process. Nowadays and due to the lack of the needed tools availability to perform this action automatically, it is accomplished manually. Usually, the time consuming method is used by back-tracking the failure on an actuator due to the corresponding sensors. This paper analyzes the software quality metrics and their application on the PLC programs. Aiming to implement metrics that gives predictive information about diagnosability of an Instruction List (IL) PLC programs, this could minimize the needed effort to check the program in case of mistakes. Furthermore, to get a better prediction about diagnosability, new metrics are introduced which are able to give more information about the semantics of a program. But they are not yet fully developed and have to be analyzed.

Abstract: Background: Diabetes mellitus (DM) prevalence is increasing in Arabian Gulf countries and Saudi Arabia is ranked as the 7th country world widely estimated to have the highest numbers of people with diabetes in 2000 and 2030. Objectives: This study intended to estimate the prevalence, risk factors of diabetes among adult population of Jazan region, Saudi Arabia. Methods: Observational cross sectional survey conducted among adult Saudi population aged 15 years of age and over who attended eight Primary Health Care Centers (PHCCs) in Jazan region. Standardized questionnaire as well as diabetic registry was utilized for this research. The questionnaire involved risk factors of DM and sociodemographic variables. Statistical analysis involved: chi-square test (or Fisher exact test where applicable) was used to evaluate the prevalence of DM among different sub-groups. The crude odds ratios (OR) were estimated by univariate analysis to observe the association of each variable with DM. Results: The overall prevalence of DM among study participants was found to be 12.3% (95% CI: 10.9 - 13.8). The prevalence of DM according to gender showed that women are of significantly higher prevalence 19.0% with confidence interval (95% C.I. 15.9 - 22.6), compared with only 9.8% for male (95% CI. 8.4 - 11.4). Participant’s body mass index, age, family history of diabetes and daily exercise and work involved physical activities that showed a significant association with DM. Conclusion: Increased prevalence of diabetes calls for urgent steps towards prevention and health promotion, programs designed to reduce its burden.
