Endometriosis affects approximately 10% of women and girls of reproductive age. The present study was designed and implemented with the aim of determining the relative frequency of endometriosis symptoms and related factors in women referring to health and treatment centers in Yasuj, Iran, in 2023.

In the present descriptive-analytical study conducted in 2023, the studied population were non-pregnant women of reproductive age of 15-50 years who were referred to health centers of Yasuj, Iran, and 865 of them were selected by convenient sampling method. The participants were interviewed with the self-assessment questionnaire included in the educational booklet of the Ministry of Health, Treatment and Medical Education, including 12 symptoms of endometriosis, in order to identify suspected cases of the disease, if they have five or more symptoms. The data was analyzed with SPSS version 27 statistical software and using descriptive statistics indicators such as mean, standard deviation, frequency distribution tables and inferential statistics of Chi square test.

The findings indicated that the highest frequency of endometriosis symptoms related to irregular menstrual periods in the last 6 months was 413 (47.7%) and the lowest was infertility in 91 (10.5%). In 209 (24.2%) they were suspected to have the disease and 94 (10.9%) had a history of endometriosis. The frequency of endometriosis symptoms in women aged 21-30, married, housewives, with a family history of endometriosis, history of using tobacco in the last 6 months, exposure to tobacco smoke, daily use of caffeinated substances were significantly higher(p<0.001).

In the present study, approximately a quarter of women of reproductive age needed to be referred to a specialist physician and follow-up due to the possibility of contracting this disease, which indicated the importance of screening women of reproductive age and timely diagnosis of this disease in order to prevent its complications and consequences, including infertility.

Reproduction (regeneration) is a fundamental process that drives the dynamics of a forest, occurring continuously in a healthy and natural forest with a specific spatial and temporal pattern. Natural regeneration poses significant challenges in Zagros forests, Iran. This research was undertaken to examine and analyze the current state of reproduction of tree and shrub species in the monitoring sample plots of Zagros forests. This study, while scrutinizing the species composition, origin, distribution curves, and health of seedlings and saplings, explores the interrelationship between reproduction and nurse species. It will serve as the foundation for long-term studies that determine the temporal changes in reproduction and its characteristics in the Zagros forests.

This research was conducted in the permanent monitoring plots of Zagros, spanning from West Azerbaijan to Fars province. A total of 120 sample plots of 100 square meters were studied within these plots. Each province had 30 studied sites in the typical forests, with 10 of them located in the protected forests. The variables studied included reproduction density by species, origin and type of reproduction, nurse species, height of seedling, terminal bud, and health status of reproduction. A height of 0.5 meters was set as the criterion to distinguish reproduction. The t-test was used to compare parametric data in two groups, while the Kruskal Wallis and Mann-Whitney U tests were employed for non-parametric data.

In the studied area, the reproduction of 20 forest tree and shrub species was recorded, and the density of seedlings and saplings was calculated to be 366 plants per hectare. However, the reproduction was not uniformly distributed, with 37% of the sample plots lacking reproduction. The abundance distribution diagram in the height classes revealed a decrease in the number of oak (Quercus spp.) and hawthorn (Crataegus spp.) reproduction with a height of less than 5 cm. Of the total number of recorded reproduction, 72.5% originated from seeds and 25% were shoots. Overall, 66% of reproduction was dependent on nurses, with oak, hawthorn, stone, and rock playing the greatest roles as nurses. Stones and rocks played a more significant role in the revival of seedlings. Cerasus microcarpa (C.A.Mey.) Boiss., Q. infectoria Oliv., and Q. libani Oliv. had the highest dependence on the nurse, while Pyrus spp., Daphne mucronata Royle, and Crataegus spp. had the least dependence on nurse species. Reproduction sheltered by nurses was significantly healthier than those without nurses. Also, reproduction sheltered by stones and rocks had a higher health rate than reproduction sheltered by trees, although this difference was not significant. Lonicera nummulariifolia Jaub. & Spach, Fraxinus angustifolia Vahl, and Acer monspessulanum L. had the worst condition in terms of reproduction. Despite the presence of mature trees, they had no reproduction (L. nummulariifolia and F. angustifolia) or had very low reproduction (A. monspessulanum). The results showed that the number of reproduction in protected sites was higher than non-protected sites. Although this difference was not significant, the reproduction in the protected sites was significantly healthier.

The results indicated that the reproduction in the Zagros forests is not in a normal situation. However, given suitable spatial and temporal conditions, reproduction occurs and establishes. Although in conditions of disturbance and overgrazing, reproduction attempts to survive by taking shelter near stones, pits, or under thorny shrubs, the conservation of the forest stand by maintaining the tree canopy (oak, hawthorn, and other species) and the forest’s natural structure provides the best conditions for the establishment and survival of reproduction, thereby ensuring the sustainability of the ecosystem.

The expansion of the use of the Internet and virtual networks among teenagers has provided a platform for exposure to some cyber violence. The present study was conducted with the aim of determining the mediating role of internet addiction, internet roaming and social exclusion in the relationship between social support and cyberbullying among second year high school students in Shiraz using path analysis method.

Research, application and the method of collecting and analyzing its data is descriptive of the correlation type. The research population is the students of the second year of high school in Shiraz city in the academic year of 2001-2011. 381 people were selected by multi-stage cluster sampling and answered a self-report questionnaire consisting of internet victimization and internet harassment subscales, perceived social support questionnaire, internet addiction scale, internet roaming scale and social exclusion questionnaire. . The data were analyzed using path analysis method and Imus software.
 

According to the findings, internet addiction, internet roaming and social deprivation play a mediating role in relation to cyber immorality.

If students have social support from family, friends, and important others, they will be less likely to be cyber-bullied in the face of cyberspace harm.

By behind the scene truth, we mean interpretation of a mathematical result. This means that we setermine that mathematical result is manifestation of which higher truth. There, we will try to find that Chebotarev's density theorem, which both its formulation and its proof had a determining role in the history of algebraic number theory, is manifestation of which higher truth.

In this ‎paper‎‎, ‎we study the historical background of class field theory‎. ‎First‎, ‎we investigate Kummer's theory‎, ‎which is one of the algebraic backgrounds of class field theory‎. ‎Then we turn to Comer's youthful dream that led to the question of finding all Abelian extensions of number fields‎. ‎After this‎, ‎we state Takagi's theorems and finally study Hilbert's problems‎. ‎By examining the historical course of the above‎, ‎we are trying to present a better picture of the historical background of class field theory‎, ‎which is one of the basic foundations of mathematics.

There exists a continuous family of disjoint smooth curves, partitioning the unit square, such that one can choose only one point from each curve to construct a measurable set whose area is equal to 1. This contradicts our intuition which resembles Cavalieri’s principle and Fubini’s theorem! So, what is the problem? In this note, we discuss the theorem (due to A. Katok) and answer this question.

The main purpose of this current study is Presenting Causal Model of Goals Orientation Dimensions Relations and Academic help seeking with the role of academic engagement and self-efficacy occur in analysis method. The research  method was correlation. The population includes all high school students (second level) in Shiraz city (N=43700). According to the Cochran formula, the sample size was 265 people who were selected by multi-stage cluster sampling method. For data collection used academic help seeking questionnaire (Ryan & pintrich), academic engagement (Brink Lynn & pintrich), goal orientation (Elliot & Mc Greger) and self-efficiency (Morris).

According to the results, education goal orientation and its component through academic of the indirect effects to students' academic help seeking. All variables in this study of current changes explain 0/37 of help seeking variable.  Paying attention to fit features is in a suitable level.

The purpose of this study is to identify and classify the dimensions and components of the employee engagement for indigenous and authentic knowledge in accordance with the Holy Quran guidelines and the translation of Sharif al-Mizan's interpretation.

In this study, using the MAXQDA 11 software, the 20-volume interpretation of al-Mizan in the use of the NOOR Comprehensive Software was reviewed and coded.

In this context, more than 284 primary topics were identified which reduced to 104 after final refinement. Primary themes were grouped into 29 main themes and then organized in the form of 8 organizer themes. The 8 organizer themes were categorized as two general themes of individual and organizational engagement.

From the Qur'an's point of view, engagement refers to the individual aspect and pays particular attention to the nature of man; therefore, paying attention to one's belief system and nurturing it according to human nature leads to the formation of one's inner beliefs and desires in order to reach the Lord's satisfaction and one's happiness and engagement.

The reliability of structures under different loading conditions is the main objective of civil engineers. Progressive collapse is a catastrophic phenomenon which has been of greatest interest to many researchers and engineers during the last decade. The incidence of diverse accidents such as burst, fire, vehicle collision, miscalculation, mistake in construction can result in a partial failure in a structure, which sometimes extends to collapse the majority of or entire a building. This phenomenon is called the progressive collapse. This collapse is defined in some regulations in the same way. For example in NISTIR-7396 ``the progressive collapse is the expansion of a primary damage triggered by a primer incident from an organ to others consequently causing either major or entire damage to a construction''. The main aim of this project is to study the reaction of the steel moment frame with the rigid connection of SP, WUF-B and RBS under the progressive collapse.To pursue the study, we used six-, nine- and 12-floor buildings representing short, mid and tall structures equipped by the steel moment frame system. The alternative path method and UFC 4-023-03 regulation were used as standard methods to estimate the progressive collapse. The modelling of the buildings was run by software SAP 2000 which is in 3D, and then non-linear dynamic time history performed to analyze the data. Moreover, we predicted the different scenarios of column removals regarding the regulation criteria in order to study the progressive collapse.The results from the alternative path method showed that unlike the WUF-B and SP connections, the RBS has more potential resistance due to higher ductility. Furthermore, the tall buildings presented the better resistance against collapse as well, because of the higher indeterminate degree. The results from column removals in the given models showed the more destruction in the upper floors unlike the removals of columns in downward floors.

Humans are always exposed to ionizing radiation that could potentially have harmful effects. The aim of this study was to evaluate the background gamma dose rate, the estimated annual effective dose, and the excess cancer risk assessment in Dargaz. This study was a cross sectional study which was conducted in January- March and July – September 2016. In this study, 5 stations (4 in the main geographical directions and 1 in the center city) were selected based on the map of the city to determine the dose rate of background gamma radiation in outdoor areas. A dosimeter was used (Geiger Müller detector STEP OD-02 with sensitivity of 0-2000 mSv/h) to measure gamma rays. The device was designed to monitore X-rays, gamma rays and beta rays. The results showed that the maximum and minimum mean values of background gamma dose rate were 147±12 nSv/h and 113±11 nSv/h in the center and west-direction of the city, respectively. The annual effective dose for Dargaz residents in outdoor was determined to be 0/15 mSv/yr, and the amount of excess lifetime cancer risk was estimated as 0.6×10-3. The results indicated that there are significant differences between the rates dose in the center and other parts of the city (p≤0.05).

This study was conducted with the aim of investigating the effect of providing specialized training for learning disabilities to teachers on dictation achievement of students with learning disabilities in third grade elementary school. For this purpose, using purposive sampling, 16 third grade elementary school teachers were chosen. Thirty one students with learning disorder (previously identified) were from their classes. They were then assigned to two experimental and control groups (8 teachers in each group). The experimental group participated in nine sessions of the learning disabilities training course. It should be noted that the dictation achievement of students with learning disabilities was measured before and after the teachers’ training course. ANCOVA results showed that the dictation achievement of students with learning disabilities whose teachers were in the experimental group was significantly better than other students.
