Abstract
In the current research, based on the descriptive-analytical method, the phonological and morphological changes of Persian loanwords in the process of localization, as well as the influence and impact of the Persian language on the Ottoman Turkish language, have been studied. For this purpose, by referring to all the dictionaries, the dictionary of definitions and allusions, thematic dictionaries and encyclopedias that were written during the period of the Ottoman Empire in Anatolia, the data required for this research, which were about 6000 Persian loanwords, were collected and examined. In this research, using Excel software and with the help of computer, the percentage and frequency of occurrence of common processes in the field of phonology and morphology have been determined. The results of the research show that among phonetic and phonological processes including vowel harmony, phonetic over differentiation, assimilation, metathesis, insertion, omitition, lenition, and weakening; Vowel harmony, which is one of the prominent features of Turkish as an agglutinating language, has the highest frequency. In the morphological field where the processes of composition and derivation were examined, derivation has the most frequency. Despite the different typological characteristics of the Persian and Turkish languages, the relationship between these two languages has been extensive and its consequences have been remarkably one-sided, the consequence of which is the existence of many Persian words in the Ottoman Turkish language.

Abstract
Soil stabilization techniques have traditionally relied on cement or lime, yet there remains a significant knowledge gap regarding the mechanical behavior of soil treated with innovative materials. Addressing this gap, this study delves into the mechanical properties of soil stabilized with polyurethane (PU) foam, nano-silica, and basalt fiber. Through rigorous experimentation, unconfined compressive strength (UCS) and direct shear tests were conducted on reconstituted silica and calcareous samples, each treated with various combinations of these additives. A comprehensive examination of parameters such as additive content and curing time was undertaken to elucidate their effects. The results unveiled a noteworthy enhancement in UCS and shear strength parameters (cohesion and friction angle) with the incorporation of PU foam, nano-silica, or their amalgamation with fiber. Particularly striking was the superior performance observed with the combination of PU and basalt fiber, showcasing remarkable improvements in the mechanical behavior of both silica and calcareous sand, especially when considering shorter curing times. The synergistic effects of PU and basalt fiber proved instrumental in fortifying the soil's structural integrity against environmental challenges. Furthermore, it was consistently observed that calcareous samples exhibited elevated UCS, and shear strength values compared to their silica counterparts. This discrepancy underscores the inherent differences in mechanical behavior between these two types of sand, highlighting the need for tailored stabilization approaches. Moreover, the investigation delved into the failure patterns and microstructural changes within the stabilized samples, employing Scanning Electron Microscopy (SEM) for detailed analysis. This microscopic examination offered valuable insights into the efficacy of the stabilizing agents and their impact on the soil's mechanical properties. For instance, SEM imaging revealed significant bonding in fiber-reinforced samples, indicating enhanced load transfer mechanisms. Similarly, the presence of clusters of nano-silica particles adhering to sand particles showcased an improved cohesion within the stabilized soil. PU-stabilized samples, on the other hand, exhibited a cohesive layer enveloping sand particle, thereby enhancing interparticle connectivity and overall stability. The superior performance of PU over nano-silica was underscored by its ability to create a more cohesive matrix and foster stronger interparticle bonds, as evidenced by the SEM analysis. In conclusion, this study sheds light on the potential of innovative stabilization materials such as PU foam, nano-silica, and basalt fiber in bolstering the mechanical properties of soil. The findings not only offer valuable insights into the efficacy of these additives but also pave the way for the development of tailored soil stabilization techniques geared towards enhancing infrastructure resilience and sustainability.

Abstract
Child sexual abuse is one of the social problems that has devastating effects on various aspects of children's personality. In this article, an attempt has been made to examine the psychological consequences of sexual harassment in related to children. The main purpose of this study is to identify the psychological, behavioral, cognitive and emotional consequences of sexual victimization of children under 15 years of age among those referred to four social emergency centers located in Tehran province.
In this research - which is quantitative in terms of type and descriptive-analytical in terms of method - First, different indicators were selected as the effective factors of sexual victimization and each of the selected data was entered into the statistical tables using the available sampling method and using the researcher questionnaire. Then, the relationship between the variables was measured using statistical tests and the correlations were analyzed.
The results of the analysis of child sexual abuse cases referred to the social emergency confirm that there is a significant relationship between child sexual abuse and subsequent mental disorders. Hypothesis testing suggests that sexual abuse has psychological, behavioral, cognitive, and emotional consequences for children's personality. Due to the need to identify these factors in order to prevent the occurrence of psycho-behavioral disorders afterwards and increase ways to eliminate or reduce it, early detection of child abuse, intervention, treatment and prevention of horrific complications of child abuse seems necessary.

Abstract
Vitamin D is one of the essential metabolic and physiological processes in the human body. Generally all people need 200-600 IU daily (Koutkia, Chen & Holick 2001). Production of vitamin D in the skin depends on some factors such as age, skin pigmentation and the amount of ultraviolet B (UVB)) available. The amount of UVB radiation is affected by geographic location, season, time and level of atmospheric pollution. The highest amount of vitamin D is provided to sunlight exposure (Gartner & Greer 2003) as well as obtaining from oily fish, fortified foods and supplement. The recommended vitamin D receiving depends on age, gender and deficiency treatment (Dobnig et al 2008).
Despite excessive oral vitamin D intake cause toxicity (Koutkia, Chen & Holick 2001), excessive sunlight exposure cannot cause vitamin D toxicity because UVB converts excess vitamin D3 to biologically inert isomers (Holick 2007).
Different factors like physical inactivity, chronic acidosis, malnutrition, delayed puberty and mal-absorption effect on bone mineralized (De Schepper 1990).
Parathyroid hormone (PTH) compensate for reduced serum calcium with calcium absorption from the bones, causing bone deformities and that this action has been done through activating osteoclasts inhabit. Excessive activate osteoclasts inhabit can lead to osteoporosis and increased PTH and serum calcium or metastatic calcification (Holick 2007).
Severe vitamin D deficiency with corresponding elevations of PTH were reported in 88% of women who presented with muscle pains and weakness. Myalgia is generally the first manifestation of vitamin D deficiency(Glerup et al 2000). Vitamin D deficiency affects in all parts of the body (Gartner & Greer 2003).
The high prevalence of vitamin D deficiency in patients with unspecified origin musculoskeletal pain was observed in the existed evidence (Gartner & Greer 2003). These studies represent there is significant relationship between unspecific pain and vitamin D deficiency that this relationship is independent of age group (Gartner & Greer 2003).
There is a strong relationship between vitamin D deficiency and persistent non-specific musculoskeletal pain. Therefore, the patients who suffering from unknown origin pain may be required to control their serum levels of vitamin D consequent to vitamin D therapy (Mascarenhas & Mobarhan 2004).
Studies have also shown that vitamin D therapy could improves extensive clinical complains regarding their bone pain and muscle weakness of women who referred to different clinics (Torrente de La Jara, Pecoud & Favrat 2004).

Abstract
Due to increasing global pressure on the environment caused by human interventions, the studies on interaction of traditional building and their components with nature has been increased. These studies attempt to identify natural building design and determine how to use them in the climatic design of today's architectural design. Building performance simulation enables the examination of the effectiveness of innovative energy efficiency measures and control strategies. Daylighting is an effective approach to allow architectural design and construction practice to have a more flexible design of building facade, and to enhance a more energy-efficient and greener building development. Energy savings resulting from daylighting not only would mean low electric-lighting and reduced-peak electrical demands, but also it means reduced cooling loads and the potential for smaller heating, ventilating and air-conditioning. The absorbed solar radiation acts to raise the surface temperatures and consequently the temperature of the adjacent air layers. This has a significant effect on the generated thermal conditions, which is, in turn, reflected on the thermal behavior of the surrounding habitable spaces. In tropical areas, especially in warm humid areas, the need for shade and air ventilation are most important factors used for the provision of thermal comfort. In climatical and morphological studies of dezful historical context, great appliance of shade and ventilation can be seen. Among the hundreds of ways to do this, one of them is using khavoon (brick work) that creates shadow on the inner and outer walls and increase visual richness of the environment. This paper attempts to understand patterns of the brick khavoon in the way they were used; and to evaluate their shadows. These patterns became 3D using schetchup software and their shadow have been prepared at different hours of day and different directions. The amount of shadow has been calculated and analyzed by the image processing, IMAGEJ software. It seems that such patterns, in different orientation, increase amount of shadow (2.5 - 4.5 times). Given the size of the hourly solar radiation on the walls in each direction, the best direction of using this patterns can be identified.

Abstract
In recent years, with the advancement of nanoscience, many scientists have used nano materials to solve existing problems in various sectors of oil industry. Nanofluids made with these materials can facilitate the separation of oil and gas in a reservoir and increase oil recovery factor compared to current methods. Therefore, in this work, the effect of clay nanoparticles on oil recovery factor was investigated. For this purpose, two different base fluids, water and ethanol, were used to disperse the nanoparticles. The effect of adding clay nanoparticles on viscosity changes and interfacial surface tension was determined. Also, in order to investigate the effect of nanoparticle concentration in the base fluid on the ultimate oil recovery factor, nanofluids with 3 and 5 wt% were prepared. Results show that oil recovery factor increases significantly in these conditions by adding them into the base fluid, though nanofluids included clay nanoparticles have less stability. Also, the effect of these nanoparticles dispersed in water is greater than in ethanol. For example, at 5 wt%, oil recovery factor for water based nanofluid was 49.7% and for ethanol based nanofluid was 46%.

Abstract
The attitude or behavior, which is not based on logical actions- and cause and effect relations, has irrational origins; it happens due to a person's fear, threat, habits, and the unknown factors which he she believes to prevent the unbecoming events, called “superstition”. An increase in the literacy level and the popular culture in the society leads to a decrease in superstitious beliefs. It must be acknowledged that even modern people cannot reject superstitions, or get rid of them actually. This study has examined the causes of these prevalent beliefs and the way people apply them, via content analysis. Although the prevalence of superstition origins is established on irrational bases, people have applied them to gain benefit by impelling and propagating the folklore, preventing harm by inhibition, alleviation, turning the evil (scapegoat), and empathy.

Abstract
Analysis of the spatial and temporal trends of precipitation and temperature are pertinent for future development and sustainable management of water resources in a given region. In this paper, we present a study concerning the climatic behavior of two principal observables Variables, viz. monthly temperature (maximum and minimum) and mean precipitations obtained from the measurements carried out in 60 Iranian meteorological stations for 40 years from 1969 to 2008. The Mann-Kendall test was used to detect the significant trends.Results showed that during summer and autumn, the precipitation had a negative trend (at 5% significant level) in the south-eastern parts of Iran and this trend is less during spring, but no special trend was observed in winter. The minimum and the maximum temperatures did not have any particular trend in winter. Spring was accompanied by an increase in positive trend in the maximum temperatures in the south-west and north-east, while the minimum temperature only limited in the south-west parts. Positive and negative trends of the minimum temperature were very dispersed during the summer. The maximum temperatures had a negative trend in the north-west and no positive trend was observed at 5% significant level. During autumn, the temperatures indices had positive and negative trends with a wide range of dispersion.
