Abstract
Aims: Evaluation of Patient Satisfaction (PS) is one of the most essential factors in improving the quality of healthcare systems. The aim of this study is to determine the norms and to evaluate the validity and reliability of the Najmiyeh Outpatients Satisfaction Questionnaire (NOSQ). Methods and Materials: This study has been conducted on 240 outpatients in Najmiyeh subspecialty hospital (Tehran-Iran) in 2011. They were selected using the proportional simple random sampling method. Following the confirmation of the content validity, we considered the construct validity and reliability applying Confirmatory Factor Analysis (CFA) and Explanatory Factor Analysis (EFA) and Cronbach's Alpha. Also, SPSS and AMOS version 18 were used for data analysis. Findings: The sample population consisted of 240 subjects, including 132 females (55.1%) and 108 males (44.9%). The EFA reported three important factors in this regard, with a variance of 54% and Kaiser-Meyer-Olkin index of 0.82, all approved by the CFA (RMSEA= 0.04, CFI= 0.96). The outpatients' satisfaction factors were: “hospital information system, treatment and conditions”. The reliability of the questionnaire was reported at %71 based on the Cronbach's alpha. Conclusions: Both validity and the reliability indexes of the NOSQ have been reported at a desirable level; therefore it can be used as a valid and reliable instrument to measure the outpatients' satisfaction.

Abstract
Aim: Patients' satisfaction (PS) is a dominant concept in medical care, due to the gap in the literature on Persian version of PS instruments, this study has conducted with aim to analyze the validity and reliability of self-designed Najmiyeh Inpatient Satisfaction Questionnaire (NISQ). Methods: This study was carried out on 247 inpatients that came in Najmiyeh subspecialty hospital in Tehran (the capital city of Iran) during year 2011 who were selected by proportional stratified sampling method. Statistical analysis used: In this study, after checking content validity we used confirmatory and explanatory factor analysis and Cronbach's Alpha in order to examine construct validity and reliability, respectively. SPSS (version18) and AMOS (version 20) programmer were used to analyze data. Findings: Samples consisted of 247 subjects (222 women (90%) and 25 men (10%)). The explanatory factor analysis showed 5 factors with 64% total variance and 0.91 Kaser-Meyer-Olkin Index, the result also confirmed with confirmatory factor analysis (PNFI=0.71, RMR=0.03, PCFI=0.76). Extracted factors consisted of: “satisfaction from nursing services and their behaviour”, “satisfaction from one’s doctor”, “satisfaction from inpatient department”, “companions’ satisfaction”, “satisfaction from one’s room”. Also the questionnaire’s reliability was 0.96 using the Cronbach's Alpha method. Conclusions: Because validity and reliability indexes of NISQ were reported in suitable range, we can confirm that this questionnaire is a valid and reliable tool for measuring inpatient satisfaction.

Abstract
Background: Age-related differences in the ethoxyresorufin O-deethylase (EROD) activity of CYP1A1 and its inducibility in rats may determine the toxic potential of acetaminophen. This study was carried out to compare the effects of acetaminophen (APAP) and β-naphthoflavone (βNF) on CYP1A1 activity in young and adult rats.
Methods: For this purpose, young and adult rats (n = four / group) were treated with different doses of APAP. Likewise groups of young and adult rats were treated with a single dose of β-naphthoflavone (βNF, 67 mg / kg b.w). EROD was measured in microsomal fraction using resorufin as the substrate.
Results:The results showed that a single i. p. injection of APAP (25 mg / kg B.W.) failed to alter liver microsomal EROD in young and adults. Whereas, in adults treated with 250 and 450 mg APAP / kg B.W, liver CYP1A1 was elevated to about 45 and 60% respectively. The rate of CYP1A1 induction in young rats with single dose of APAP (450 mg/kg B.W) was approximately 32%. Induction in CYP1A1 was noticed 4 h after APAP injection and returned to normal levels in 24 h. The inducibility of CYP1A1 in rats treated with a toxic dose of APAP was comparable to the data obtained from animals treated βNF, 67 mg / kg b.w.
Conclusion: These results together with our previous reports indicate a similar pattern of changes in CYP1A1 in both the age-groups treated with toxic doses of APAP may suggest that the inducible CYP1A1 can equally contribute to protection against liver damage in young and adult rats.

Abstract
Background: Fusobacterium necrophorum as a non-spore-forming Gram-negative anaerobic bacillus is an important human and animal pathogen. It may cause severe systemic infections (Lemierre's syndrome) and some other infections. The aim of this study was to subtype Fusobacterium necrophorum by using PCR methods. Materials and Methods: Twenty five strains of Fusobacterium necrophorum subspecies funduliformis were used. Extraction of DNA and typing of the strains using REP-PCR, ERIC-PCR and BOX-PCR were done. Results: Molecular typing of Fusobacterium necrophorum using REP1-R-I and REP-2-I primers generated 2 to 5 amplicons ranging in size from 1500bp to 2000bp. GelCompar comparison of banding patterns revealed seven distinct ribotype strains from 25 strains tested of which most were 2 and 4 with 8 and 7 strains respectively. BOX-PCR subtyping generated 2 to 7 comparable amplicons ranging in size from approximately 600bp to more than 2000bp. ERIC-PCR subtyping generated 6 to 11 amplicons ranging in size from approximately 100bp to 1500bp. Conclusions: F. necrophorum strains have genomic variations that suggest they are never truly clonal in nature, or they may have undergone localized genetic variation across worldwide. This study also showed subtypes existing in Fusobacterium necrophorum species. We have demonstrated that Fusobacterium necrophorum REP-PCR types can be divided into seven, three subtypes by BOX-PCR and six subtypes by ERIC-PCR. BOX-PCR typing proved to be the most discriminatory method, yielding two-seven major bands. The sample size was too small to interpret statistically.

Abstract
The main purpose of this study was to determine the degree of using cognitive learning and strategies of learning by Iranian French Language Learners. Furthermore, it aimed at determining the effect of using cognitive strategies on learner autonomy. In doing so, a questionnaire of 12 questions was filled in by 38 post-graduate students of TMU. The frequency of utilization of cognitive strategies including summarizing, memorizing, guessing the meaning of words, repetition, extra-curricular practicing, learning through comparative reasoning, note taking, using mnemo techniques, paraphrasing, review and research is studied. The results of Freidman test showed that the difference between the mean ranks was significant, and the most frequent strategies were note-taking (76.3%), guessing the meaning (75.65%), and elaboration (71.71%). In general, the results showed that among the cognitive strategies, there was almost a correlation between documentary research and extra-curricular activities. There was also a positive correlation with autonomy(58%).

Abstract
Background: Gram-negative organisms producing Extended-spectrum beta-lactamases (ESBLs) are presented as a global problem. Klebsiella pneumoniae is considered as one of the most important microorganism of this group. The prevalence rate of K. pneumoniae species is increasing, and this increase is higher in the ESBL group, indicating the increase in antibiotic resistance. We must have sufficient knowledge about regional antibiotics resistance in order to monitor the prevalence rate and antimicrobial resistance among the isolates by appropriate treatment. In this regard, the objective of our study was to evaluate antimicrobial susceptibility among K. pneumoniae isolates by E-test method in Khatam ol Anbia hospital during 2015.
Materials and methods: This descriptive cross-sectional study was carried out during 2015. All clinical samples were collected from intensive care unit (ICU) and general wards of Khatam ol Anbia hospital. All of the K. pneumoniae strains were detected by biochemical and microscopic tests. Antimicrobial susceptibility and minimum inhibitory concentration (MIC) were determined by disk diffusion and E-test methods. Descriptive statistics was used to analyze data.
Results: About 62 K. pneumoniae strains were isolated from clinical samples of ICU and general wards during one year. Of these, 38 (61.3%) isolates were isolated from intensive care unit, and 24 (38.7%) isolates were isolated from the general wards. In this review, the least resistance was related to colistin (4.8%) and Amikacin (14.5%), respectively, and the most resistance was observed to the antibiotics of ciprofloxacin (66.1%), ceftriaxone (62.9%) and gentamicin (59.7%), respectively. Resistance to imipenem was observed in 38.7% of the isolates.
Conclusion: The current study demonstrates that antibiotic resistance pattern is changing, and resistance to imipenem and colistin is rising, so this should be considered as a serious risk for admitted patients in hospital.

Abstract
Learning a foreign language, like other fields, undergoes forgetting. Paying attention to forgetting in foreign language writing and speaking abilities is more important since these two realms indicate the learner's competence and performance. This study aimed to investigate the phenomenon of forgetting of Iranian Language learners (French) at the level of language production. To achieve this objective, descriptive and analytical methods were used for reviewing the related theories of forgetting, memory and data storage. In the field study, forgetting of concrete and abstract words between two sexes and two age groups (25-30, 31- 40) was measured by two different tests. According to the results, forgetting depends on the type of words. On this basis, abstract words are more frequently forgotten. The obtained data demonstrated that age and sex have a significant impact on forgetting words. More precisely, these factors affect forgetting, when words appear in a context. So in the age group of 25-30 years, forgetting of abstract words is significant among men and 1.82% more in comparison with women. While in the age group of 31- 40 years, the forgetting degree of women is 2.5% more.

The purpose of this paper is to describe domestic violence which is a widespread problem affecting families, law enforcement agencies, and the court system Studies investigating the effects of arrests on recidivism in domestic violence cases have led to the implementation of pro-arrest policies in many police agencies. The changing policies have lead to an increase in the number ol domestic violence cases in the court system with limited prosecution of these cases. Police training in the specific dynamics of domestic violence is believed to provide officers with skills necessary in handling these calls safely and accurately, The Lakeland Police Department has developed a comprehensive community project, the Domestic Abuse Response Team (DART), that is designed to reduce the recidivism of domestic violence .in order to serve the victims more efficiently. Examination of components of this program may help to target specific aspects of the training that are useful in reducing recidivism rates, Specific attention is paid to concepts, theories, and models that support the findings that batterers and victims are reacting in a manner they have learned through their family environment and as part of a pattern or cycle of violence in which the abuse is expressed.

Abstract
Entering into the Arabic language and literature in the early Islamic centuries, Iranian culture generally turned to become a position of Arabic culture and common among the people in the 4th century (A.H.). This culture has been transferred though the language tool; therefore, it has influenced on the Iranian authors who used to write in Arabic. Abu-Hahyyan Al-Tawhidi is one of the greatest scientists in the Islamic world in the 4th century (A.D.) whose works have Iranian vein. In his book, Titled Al-Amtaa Wal-Muanassa, there are almost100 pension load words, among which 20 words, have appeared for the first time in his work, 21 words have been taken from the Ignorance Age introduced into the Arabic language, and 57 words are loan words borrowed from the Islamic and Arabic eras. The Persian loan words mainly include the names of food stuff, birds, animals, and mechanic herbs. The names of flowers, musical instruments, plays, building tools, etc. have rarely been used in this books. Since, the Persian loanwords are meaningful by themselves; hence, the goal of this study is to assign the cultural meaning/concept of Persian words, which have conveyed in to Arabic Language. As such, through knowing the Semitics of words, the kind of influencing culture can be easily specified.

Abstract
Firefly luciferase is a light generating enzyme, which is used in different fields of biotechnology and molecular biology. Luciferase has found widespread applications in many areas of genetic analysis such as detecting gene expression, reporter gene assay and proteomics studies such as protein-protein interactions. Despite many advantages, there are some limitations in luciferase-based systems, the most important of which is its low stability. One of the newly developed methods to solve this problem is to take advantage of Deep Eutectic Solvents (DES). One group of DESs is those that composed of organic salts with hydrogen donor, due to which, intermolecular hydrogen bonds cause lower melting point in comparison with each of the component. In this study, we investigated the effects of DES on kinetic properties of wild type and I232R - E354R/Arg356 mutant Lampyris turkestanicus luciferases. For this, both enzymes, wild type and mutant, expressed in BL21, the protein of interest purified through affinity chromatography and used for kinetic studies. Here, we used choline chloride: glycerol as DES. According to the results, the wild type luciferase is much more thermostable in DES than I232R - E354R/Arg356 mutant. Furthermore, the remaining activity of both wild type and mutant luciferases are greater in the presence of DES than those in the absence of DES.

Abstract
Cultural area is a geographical area in which an approximately large of group with shared cultural characteristics are present. In the Islamic period, Nishabur city (the remains of which are located in the South East of the modern city of Nishabur), Balkh, Merv and Heart were the four quarters of Great Khorasan in the early centuries until the Mongol invasion, from which only Nishabur in Iran has remained. Based on the historical and geographical sources of the early and middle centuries of the Islamic period, Nishabur has had a broad cultural context, including twelve provinces, a dozen quarters, as well as several towns and villages. Buzhgan, as one of the easternmost twelve provinces of Nishabur, is located within Nilabad Plain, 17 km southeast of Torbatejam, and has been the result of interaction between climatic conditions and political, economic and social relations as in close association with the capital city of Nishabur in the first to seventh centuryies (AH). In this paper, the literature on Buzhgan has been dealt with using a historical analysis approach. The evaluation of written sources indicates the distinct political, economic and cultural role of Nishabur as the most important eastern province in the road from Nishabur to Heart.

Abstract
Aims: Since communication problems between caregivers and the elderly cause reduction and deficiency in caring and issues such as ignoring elderly people and negligence in caring by the caregivers, therefore, this study aimed at evaluating the interpersonal communication skills of elderlies and their caregivers in Khorzugh, Isfahan province.
Materials & Methods: In this descriptive-analytical research, 140 elderly people in Khorzugh were selected by as a target community. Data collection tools were demographic information questionnaire and Queendam's communication skills questionnaire. Spss16 software, Kolmogorov-Smirnov test, Chi-square tests, and Spearman correlation were used for data analysis.
Findings: The mean and standard deviation of elderly people and their caregivers were 66.39±6.16 and 55.0+6.38, respectively. Average score of communication skills of caregivers and elderly from 170 scores was 75.83±11.79 and 90.37±3.81, respectively. The communication skills showed a significant statistical relationship with the age caregivers group and age and occupation in the elderly group (p<0.05). Also, in the elderlies, there was a significant statistical relationship between attitude toward communication with marriage status, listening with living , and emotion control with of children (p<0.05).
Conclusion: According to the results of this study, the level of communication skills of caregivers and most of the elderly was moderate regarding the importance of these skills in establishing effective communication between caregivers and the elderly. The necessity of creating appropriate conditions is felt for improving these skills and it is better to conduct educational programs to enhance the communication skills of the elderly and their caregivers.

Abstract
Abstract This comparative study examines the ar is one of the ly,rical works of the military that symbolically narrates the spiritual transformation of Bahram Gour, who housed seven martyrs from seven countries who were the symbol of their homeland's culture in seven palaces, and heard a story from them every night. The Shah overnight began on Saturday with the Princess of the Black Dome, and Adineh ended in the White Dome, which belonged to the "correctness" of the Iranian Princess. With a story centered on following Iranian culture and rationality, Dorsati transformed the Shah spiritually and brought him to immortality. While acquainting himself with Persian culture and literature, William Jones created the system of the Seven Springs based on the stories of the seven military figures. Aware of the influence of the number seven in various ethnic groups and its application in Eastern mythology, he set the foundation of the Haft Cheshmeh on the number seven, which corresponds to the seven figures in terms of morphology. , Examined the similarities and differences between the two systems and came to the conclusion that the young king of the Jones system finally evolved in dealing with a mythical maiden and reached immortality with the purification of body and soul. Haft Cheshmeh, in terms of structure and content, flows like streams from the areas of seven military palaces and calmly joins the ocean of Persian poetry and literature

Abstract
The Oriental culture, literature and myths have long been the focus of Orientalists and Western scholars. William Morris is a British poet who was interested in Persian poetry and literature. He was familiar with Persian culture and literature, and wrote “The Man Who Never Laughed Again” based on “The Black Dome” in Nizami Ganjavi’s Haft Peykar. He imitated the character, atmosphere of the story, the symbols, the colors, the costumes and other elements of the story from Haft Peykar. Haft Peykar or Haft Gonbad is one of Nizami’s lyrical poems that symbolically portrays the spiritual transformation of King Bahram of Iran. Bahram proposed to marry seven princesses from seven countries, and made them the first ladies of the seven palaces. He was the guest of one of them every night to spend time and rejoice when he heard stories. Finally, at the end of the week, when he was the guest of the Black Dome, Dorsati the Persian princess told a story about the Persian culture that influenced Bahram. This research, like other researches, has examined the impact of Nizami’s “The Black Dome” on William Morris’ work through the analysis of the content of the texts. It is based on library studies. In conclusion, this research is going to prove that William Morris’ work in terms of structure and content, like a refreshing seedling, is originated under the shade of the thick tree of Haft Peykar, then it has borne fruit in European literature.

Abstract
Condition monitoring of BLDC motors due to their important applications is gaining more and more significance. Rotor eccentricity is one of the most important sources of faults in these motors. Up to now, detection methods of this fault under nonstationary conditions are limited to complicated and time-consuming methods using wavelets and Cohen class algorithms which are difficult to implement and need heavy computations to run. In this paper a novel method based on the modified Motor Current Signature Analysis method is proposed to detect the rotor eccentricity fault of BLDC motor operating under varying speed conditions. Stator current of healthy and faulty motor which are modeled by the Finite Element Method are simulated. By changing the representation of stator current from time basis to angle basis, the current signal will become stationary. Thus there is no need for methods using time-frequency analysis. Afterwards the Order Analysis Method is applied to the simulated healthy and faulty angle-based current signal and the results are compared with each other. Finally, the fault is detected by this comparison.

Abstract
This paper gives a detailed analysis of direct torque control (DTC) strategy in a five-level drive and proposes a 24-sector switching table. The overvoltage problem due to high dv/dt is reduced compared to the 12-sector DTC. Using all vectors leads to better flexibility and reduces speed oscillations. Simulation and experimental results for a 3kVA prototype confirm the proposed solutions. A TMS320F2812 is used to implement the above strategy.

Abstract
The movement of “Cognitive Semantics” appears against the independence of the syntax from lexical domain and calls into question the semantics being peripheral as it is mentioned in Chomsky's (1982) “Generative theory”. In this regard, Fillmore's (1982) “Frame Semantics theory” is one of the major achievements of cognitive semantics. In this theory Fillmore states that understanding the meanings of words is possible through frames that each word calls for. He also maintains that “Semantic Frames” display sections of an event used for connecting a group of words to a set of meanings and the meanings of words are perceived within a system of knowledge arising from the human's social and cultural experience. In fact, the difference between Frame Semantics with other lexico semantic hypotheses is its emphasis on the background knowledge based on which the meaning of words can be interpreted (Fillmore & Atkins, 1992, 1994, 2000; Fillmore & Baker, 2010). Also, the “FrameNet Project” is a Corpus-based study based on Fillmore's theory (Fillmore, et al., 2003). It is a lexicographic research project housed and administered at the International Computer Science Institute in Berkeley, California. In this system, the meaning of words can be understood on the basis of semantic frames that are mental concepts. On the other hand, verbs are present as the most important element in most of the situations of an event and play significant role in the interpretation of the meaning; thus, working on it is a useful idea.
The purpose of this study is to present a quantitative and corpus-based analysis in order to recognize the semantic domains and frames of the verb “Goftan” (to Tell) in Persian and sketch its main frame within the framework of Frame Semantics theory and the fact-finding model of FrameNet lexicography. In fact, it attempts to investigate what Fillmore and his colleagues did in English FrameNet and others in different languages as well as in the domain of Frame Semantics to be considered in Persian too. So, the main questions of this study are:
- What are the semantic domains and frames of the verb “Goftan” (to Tell) in Persian based on the major concepts of Frame Semantics theory and FrameNet?
- Is it possible to design the main semantic frame of the verb “Goftan” (to Tell) in Persian?
To answer these questions, the authors investigate the background of studies and introduce Frame semantics theory and FrameNet lexicography. Then, they tried to be familiar with the verb “Goftan” and it’s frequency in Persian based on Persian Language Database (PLDB). To this end, 44 semantic domains and frames of the verb “Goftan” were recognized using encyclopedias, Persian contemporary corpora and FrameNet database. Then, the concept of “bar zabân Ɂâvardan va bayân kardan” (to express) was determined as the main meaning and prototype of this verb and for the first time its “Radial category” the authors sketched. Finally, the main frame of “Goftan” was created using principles and concepts proposed in Fillmore's Frame Semantics theory
