Aim: Currently, the issue of adolescents’ health literacy is particularly important because it is an essential component in improving their quality of life. Due to the lack of enormous studies on this issue, this study aimed to determine the level of health literacy and factors influencing it among high school students in Tehran, Iran.
Methods: This research is a cross-sectional and descriptive-analytic study, which was conducted on 400 male and female students studying in the second period of high school, who were selected using multi-stage random sampling. Data were collected through a questionnaire, which included personal characteristics, and the questionnaire of HELMA (Health Literacy Measure for Adolescents). The obtained data were analyzed using SPSS 20 and descriptive statistics as well as t-test and ANOVA tests.
Findings: The mean age of students was 17.01±0.87 years. 50% (n=200) of the participants were female, 50.5% (n=202) were from the North part of Tehran, and 34.5% (n=138) were in the third grade. 37.5% (n=150) had inadequate health literacy, 37% (n=148) relatively adequate health literacy, 22.5% (n=90) adequate health literacy, and 3% (n=12) excellent health literacy. Health literacy was correlated significantly with the level of education, parents’ education, source of information, the assessment of health status and interest in the issues of health (p<0.05).
Conclusion: The results indicated that most of the students had limited health literacy. Due to the role of health literacy in promoting the adolescence quality of life, it is necessary to pay more attention to promote health literacy and gain sufficient skills in order to make health information be practical and working.

Stroke can negatively affect a person’s ability to utilize properly acoustic measurements as a cue to prosody at the sentence level. The objective of this study was to determine the nature of the prosodic disturbances in Persian Broca’s aphasics at the sentence level in the framework of Autosegmental-Metrical Phonology. The subjects of this experimental study included three Persian-speaking males. They were selected by simple purposive sampling method from patients directed to the speech therapy unit in the Ghaem Educational, Research and Treatment Centre (Mashhad, Iran). Aphasic subjects sustained a lesion to the left hemisphere and particularly to the Fronto-temporal region. Acoustic measurements of duration, intensity, and terminal components of fundamental frequency (F0) that distinguish statements from their yes-no question counterparts were examined in the reading task in Persian-speaking aphasic patients. The findings of the present research revealed that the aphasic individuals were able to produce statements from their yes-no question counterparts in terms of terminal components of fundamental frequency (F0); however, they demonstrated a poorer performance than the control group. So, generally speaking, the present study confirms that linguistic ability of Persian-speaking aphasic patients to differentiate statements from questions may be preserved to some extent. The findings also support the notion that the left hemisphere may be important in the production of prosody and the Fronto-temporal region is sensitive to sentence-level prosodic contours.

The sociological study of the impact of the clergy's approaches, on the transition to democratic procedures of governing the society, has many advantages over the theological study of relationship between religion and democracy. This impact can be inferred and began from social movements of the first half of 20th century in Iran. The most appropriate approach for investigating this issue is comparative-historical analysis, and three democratic transitions in three historical periods- Constitutional Movement, the Nationalist Movement in the first cabinet of Mussadegh, and the Nationalist Movement in his second cabinet- are appropriate for comparison. Theoretical studies in the areas of cultural change (Secularization theories regarding modernity and religion), social change (world-system theories and social movements), and political change (transition theories), provides a useful theoretical framework from which it can be extracted a model to explain the transition in Iran, according to the conditions of Iran's history and the world during the period. This model will be on the basis of historical comparison of the three democratic transitions, and will be examined by method of agreement, Boolean analysis and ordinal comparison. In this scientific test, accurate understanding of causal factors in the transition to democracy in Iran will be provided. Theoretical and practical revisions of religious elites in the face of the modern world, as well as, contexts, causes and political consequences of the transitions will be clarified by narrative analysis, and finally, the position of the clergy's approaches among the causal factors of the transition will be understood. Religious leaders were influenced by macro transition contexts, and they created relatively stable and unstable changes in religious institution. Their appropriate and inappropriate positions to the transition process and their effective functioning in transition process are usually important to the transition.

In the framework of stylistic discourse analysis, literature is a container to express ideas and concepts which are not only relevant to their creator, but also they are in connection with the context in which the text is produced. Yet, literature is the product of discourse where it is developed and all factors like environment, context, cultural issues and dominant ideology of the period in which the specific text is generated affect the growth and visibility of it. In Persian literature, Khorasani style is the product of discourse that its dominant face is full of philosophical thoughts and particularly rationality. This period is influenced by rational thoughts and intellectuality and NaserKhosro's poems, as one of well- known and effective poets and one of the most noticeable representatives of 5^th century literature, is regarded as a dominant sample of this conceptual indicators. Notable point in his poems is the influence of philosophical and religious thoughts, so that a large part of his odes court was devoted to this subject matter. In stylistic layered analysis of this poet's odes, dominant and cultural discourse of Khorasani period in which frequency of philosophical and logical subjects are notable shows specific style of the poet. In this study, based on stylistic layer analysis, in order to specify appearance of dominant- intellectual and cultural discourse of the period in the light of lexical and syntactic style, two layers of vocabulary and syntax of a number of his odes' court are analyzed.

Aims: Diabetic Neuropathy Pain (DNP) is a chronic condition that arises from nerve damage caused by prolonged hyperglycemia. It leads to burning, tingling, and sharp pain, primarily in the extremities. This study examines the effectiveness of Cognitive-Behavioral Therapy (CBT) in mitigating recurrent negative thoughts, reducing anxiety sensitivity, and enhancing emotional adjustment in individuals with DNP.
Method and Materials: The study employed a quasi-experimental pre-test-post-test design with a control group, involving 36 patients with DNP from Ardabil clinics located in Ardabil, Iran in 2024. Patients were purposively sampled and randomly assigned to intervention (n = 18) and control (n = 18) groups. The intervention group underwent eight 90-minute CBT sessions, while the control group received no intervention. Data were gathered using the Repetitive Negative Thinking Questionnaire, Anxiety Sensitivity Index-3, and Emotional Adjustment Measure. The collected data were analyzed using MANCOVA in SPSS-27.
Findings: The results demonstrated that CBT significantly improves emotional adjustment (F = 49.46) and reduces recurrent negative thoughts (F = 45.41), as well as physical (F = 52.27), cognitive (F = 59.61), and social dimensions of anxiety sensitivity (F = 38.34) in individuals with DNP (P < 0.001).
Conclusion: The findings highlight CBT's transformative impact on the psychological resilience of DNP patients, fostering adaptive emotional regulation and diminishing maladaptive thought patterns. By addressing the interconnected dimensions of anxiety sensitivity and emotional adjustment, CBT offers a pathway to holistic pain management, emphasizing its potential as a cornerstone in the psychological care of chronic pain conditions.

By presenting the concept of Paratopy, Dominique Maingueneau gives a new definition of the relationships between text, author, and society in the analysis of literary discourse. According to Maingueneau, the creation of a literary text cannot solely be result and locus of the author's conflict with his/her society but are the consequences of the writer's presence in his/her context called Paratopy. According to him, paratopy is an essential condition for emergence of a literary text and the literary creation is a necessary criterion for paratopy's existence. Therefore, this study aims to investigate the paratopy's effect in literary discourse of two writers whom both narrated the same individual's life. Considering the importance of Hallaj in the field of Islamic mysticism, he has been constantly subject of many works. To clarify Hallaj's teachings and claims, the writers have also created narratives, describing his life. Louis Massignon and Abdul-Hussein Zarrinkoub in two works: The Passions of Hallaj and The Flames of Tour, despite using the same sources, as well as a relative agreement on the rightfulness of this Muslim mystic, have offered a rather different discourse of Hallaj's life. Understanding the reason for the attention of these two outstanding authors despite their different ideological backgrounds and approaches to historiography, as well as the differences between narrative and discourse of the two texts are questions that the authors have tried to answer. Therefore, with emphasis on Maingueneau's theories in this study, the authors examined the paratopy of the two writers and its manifestation in the two mentioned literary discourses in order to understand the genesis conditions of the two works, and also, through understanding their differences, come to a clearer reading of them.

Decision making and pedagogical reasoning are regarded as two of the important concepts underlying teaching skills. This study aimed to first identify the novice Iranian English as a Foreign Language (EFL) teachers’ initial decision making and pedagogical reasoning in terms of managerial mode. More importantly, it sought to inform the teachers’ decisions and reasoning through some one-to-one feedback sessions, which were interactively held between every novice teacher and an experienced teacher. The participants were one experienced (male) and five novice (four females and one male) teachers. To collect the data, a number of teaching scenarios, classroom observations, stimulated recalls, and the Self-Evaluation of Teacher Talk (SETT) framework were used. The analysis of the data using conversation analysis showed that the novice teachers benefited from their negotiated interactions with the experienced teacher and applied the points regarding all five pedagogic goals of managerial mode in the framework. After the feedback sessions, the teachers could confidently defend their decisions pedagogically when enquired for reasons. The findings showed that modifying the teachers’ decision would not be successfully ensured until they reached the “aha” of the moment or a new understanding, which is the last stage in reforming one’s pedagogical reasoning. One way to achieve this moment is through raising the teachers’ awareness of the essential metalanguage. It is thus suggested that officials in charge and institute managers provide such learning opportunities for teachers so that they take more serious steps toward their own professional development through such frameworks as SETT

AbstractText Self-Evaluation of Teacher Talk (SETT), comprised of four modes and 14 interactures, aims to make teachers cognizant of the importance of their classroom interactions. This study specifically elaborates on the skills and systems mode, which generally gives primacy to accuracy and is pertinent to the reading and writing literacy development course. The data were collected from five experienced elementary teachers - one female and four males - taking part in the official ‘Superior Teaching Style Contest’ of the Ministry of Education in Iran. The data were analyzed using Walsh’s (2006b) adapted SETT framework. The results showed that all of the interactures and pedagogic goals of the mode were observed in the analyzed data. Code-switching, as an added interacture to the mode, happened in all five teachers’ recorded classes, especially when moving from one activity to another. The findings of the study provided robust evidence regarding the overuse of teacher echo in the mode.

Blade forging is an intricate process due to complicated geometry, high dimensional accuracy, complicated material flow, varying and sometimes very thin thicknesses. As a powerful tool, numerical simulation is used in different steps of designing process. Mechanical properties (stress-strain curves) of the material and friction factor of contact surface are of the most important inputs of the simulation. Thus, cylinder and ring compression experiments were conducted to obtain these inputs for Al-2024 used in forging of 202 MVA Siemens generator fan blade. Because of high costs of blade forging and suitability of cylinder side-pressing this experiments were used to evaluate the compression tests and simulations. Good accordance was observed between simulation and experiment. Final forging die cavity and then preforms needed to produce a sound part are modeled. Designed preforming steps include extrusion, bending and upsetting. Blade final forging step was simulated in different temperatures of die and workpiece and strain rates and the optimum condition was determined.

Delamination is the most common failure mode in composite materials. It takes place in different modes, i.e. mode I, mode II or the combination of these modes. The present study is concerned with an investigation of mechanical and acoustic emission behavior of delamination. In this work, various lay-ups of glass/epoxy composite laminates have been used to study the delamination behavior when subjected to mode I, mode II and the mixed-mode I/II tests. First, the characterization of load-displacement curves of the specimens is done based on the AE parameters and mechanical responses and the curves were divided into three parts. The crack growth in the mode I was stable state and in the mixed-mode and mode II was unstable. In the next, interlaminar fracture toughness of the specimens, Gc, were measured using standard methodologies and acoustomechanical methodologies which is based on the mechanical behavior and AE information. It was found that the acoustomechanical method presents the lower limit of the interlaminar fracture toughness and agrees with the results that obtained from standard. The images were captured with Scanning electron microscope (SEM) from damage surfaces verifies the results that obtained from Acoustic emission.

Sandwich composites are widely used in structural applications because of their appropriate mechanical properties and low strength/weight ratio. Delamination is common failure mode in these structures that lead to a reduction in strength and stiffness of composite. In this paper, using acoustic emission, initiation and propagation of delamination in sandwich composite specimens was investigated. The specimens were loaded under mode I loading. Then the characteristics of the signals related to different damage mechanisms were specified. The acoustic emission signals were classified based on their frequency ranges. Then the acoustic emission signals were recorded during the test specimens were processed using wavelet transform. Thus the percentage of energy in each components of the acoustic emission signal was specified. Each of these components has a certain frequency range corresponding to a damage mechanism. Thus the percentages of different damage mechanisms in each specimen were specified. The Scanning Electron Microscopy (SEM) was also employed to verify the results which were obtained from acoustic emission and wavelet transform method. The results showed acoustic emission is efficient tool for identification and separation of different damage mechanisms in sandwich structures.

In this article the effect of hot rolling process on properties and microstructure of Al-B4C composite is investigated. To produce the composite samples, 3 vol.% B4C particles with 300 nm average grain size added to melted Al-356 alloy. Rolling process was done at 350 °C on vortex samples that is made after 15 minutes mixing at 850 °C. Porosimetry, hardness and tensile strength tests were carried out to investigate the physical and mechanical properties of composite samples. Microstructures of the samples were also investigated by using scanning electron microscopy. The results indicate lowering the amount of porosity, increasing hardness and increasing tensile strength of rolling composites. The amount of porosity before rolling process was 2.05% that is decreased to 0.35% after rolling process. Tensile strength and hardness of composites before and after rolling process achieved 178 MPa and 293 MPa and 62 HBN and 101 HBN respectively. Also hot rolling process caused to more ductile fracture of composites that is produced by vortex. Tensile strength and hardness of composites before and after rolling process achieved 178 MPa and 293 MPa and 62 HBN and 101 HBN respectively. Also hot rolling process caused to more ductile fracture of composites that is produced by vortex.

In this study, the first mode of stress intensity factor of semi-elliptical circumferential crack in the outer surface of a cylinder with radius to thickness ratio of 30, is investigated. The cylinder is applied in semi-submersible drilling platforms. First, the stress field of the cylinder under thermal and mechanical loads is extracted based on semi couple thermo-elastic equations. Then, the weight functions are derived for deepest and surface points using three reference loads results. Explicit expressions of stress intensity factors for surface and deepest points are presented using thermo-elastic stress field and the weight functions of the cracked cylinder. The results obtained by proposed weight functions and those obtained by finite element method and those presented in the literatures have a good accuracy. The interaction effects of thermal and mechanical loads on the stress intensity factors are studied. The results show that with increasing load ratio, the dimensionless stress intensity factors of deepest and surface points, decrease and increase, respectively.

The AISI D2 steel is a high-chromium and high-carbon tool steel which has good mechanical properties such as high compressive strength and good through-hardening. Despite these advantages, fracture toughness of this steel is moderate. In this study, fracture toughness of AISI D2 steel was determined using Finite Element and Acoustic Emission methods. Selected steel (AISI D2 cold-work tool steel) was heat treated and tempered at different conditions. Then Compact testing specimens were prepared according to ASTM E399 standard and fracture toughness of the specimens was specified according to the standard method. The specimens were modeled in the commercial FE software (ABAQUS) and fracture toughness of the specimens was determined using FEM. Determination of fracture toughness using AE technique was carried out according to three methods: Acoustic Emission Energy Rate (AEER), Acoustic Emission Count Rate (AECR) and integral of sentry function. The results obtained from ASTM E399, Finite Element and Acoustic Emission methods were compared with each other. It was found that fracture toughness values which were obtained using AECR and integral of sentry function techniques are lower bound and the results obtained from FEM are upper bound values of the fracture toughness. Furthermore, fracture toughness values obtained using AEER were the most consistent with the results obtained from ASTM E399 standard method. Finally, it could be concluded that Acoustic Emission method can be used as a useful method for determination of fracture toughness of engineering materials.
