Muscle weakness and shortness have a profound effect on the length and function of the body, causing abnormal pressure on the joints and other tissues. Deficiency or increase in flexibility is a factor in the stiffness and instability of moving parts and affects the maintenance of the desired condition. Therefore, the aim of this study was to compare the flexibility of Iranian adolescents and young people in two selected groups with healthy and spinal deformity. The statistical population of this study consisted of adolescents and young people across the country. The statistical sample consisted of 1263 girls and boys (with age range of 18-12 years old) from 5 geographical regions of the country, which could represent the whole country in terms of environment, culture, economy, and genetics and accounted for about 50% of the country's population. The flexible ruler was used to measure the arches of the spine in the sagittal plane, and the flexibility of the back and lumbar muscles, the trunk flexor muscles, and the trunk lateral flexor muscles were measured. The results showed that there was a significant difference between the flexibility of the two groups of kyphotic and kypholordotic with healthy subjects among the adolescents and young girls, and adolescent boys (P<0.05), but in the two groups, lordotic and healthy, this difference was not significant (P>0.05). The flexibility was significantly different between the gender in both the kyphotic and kypholordotic groups among adolescents (P<0.05), but in the healthy and lordotic groups was not significant (P>0.05). Finally, the results showed that there was only a significant difference between the flexibility of young girls with kyphotics and kypholordotics compared with h

Protection of the children is one of the most important concerns in international human rights law. Child marriage is recognized as one of the forms of child abuse. The first step for elimination of child marriage is legal definition of the child. Lots of treaties have tried to determine the minimum age of a person before which he or she cannot marry. This article examines the criteria for recognizing an individual as a child and consequently child marriage in the international human rights system and domestic laws of the Islamic Republic of Iran. Treaties relating rights of the child do not clarify a specified minimum age for marriage except the Convention on the Rights of the Child in which a child is defined as a person below the age of 18. This criterion is based on an age-oriented approach and is aimed at homogenization of girls and boys. In contrast, in the law of Iran it is based on an interest-oriented one and it is relied on a multiple-criteria approach comprised of legal (physical or sexual) maturity, mental growth, religious maturity and guardian consent which has resulted in a more rational and defensible approach.

Reza Shah's government can also be considered a government based on an ideology. This ideology has different components and at the same time, based on it, various institutions were created during Pahlavi's rule. Accurate knowledge of the Pahlavi government, especially in the era of Reza Shah, is obtained with a correct understanding of this ideology. Therefore, the state of the Pahlavi government is "linked" to this ideology in a very fundamental way. Looking at its situation, the three most important elements in it were considered the main ideological components of the government, which are: "authoritarianism", "monopolism" and "personalization of power". Of course, nationalism and antiquarianism can also be added to these. In this research, the focus is on the political components of the government's ideology. In sum, according to these three components, the ideological characteristic of Reza Shah's government can be considered as "concentration of exclusive personal power". In the meantime, the military institutions, which Reza Shah had placed the main support of his power on, played a very important role in the continuation of the government and the implementation of its ideology. The "police" was one of the most important of these institutions, which was completely at the service of the "person" of Reza Shah, and before and after he reached the throne, he fulfilled his wishes completely. This article seeks to understand the "problem" of the "police" in the ideology of the government with a descriptive and analytical method. And at the same time, its most important findings are that the "police" based on the principle of "concentration of exclusive personal power", was one of the main tools for creating order and suppressing Reza Shah's opponents. The most important result of this research is that the police played a role in establishing the "concentration of exclusive personal power" mostly by "suppressing and censoring the press", "dominating the elections and parliament" and "suppressing the opponents of the king". And this act was exactly based on the ideology of Reza Shah's government.
