Semantics is one of the new approaches in Quranology of the last century. This knowledge has been very effective in the growth and promotion of Quranology today and has been welcomed by Quran scholars. One of the branches of semantics is structural semantics, and among them, one of its topics is determining the semantic domains of a word. In the following article, the semantic domain of Lail in the Holy Quran is explained. The research method is textual analysis based on the pattern of accompaniment and substitution of words with the word Lail. This study shows that the words that are related to this word in the process of companionship and succession can be examined as the semantic pairs and subsets of semantic relations day and night (inclusiveness of night and day, etc. ),Phenomena accompanying the night (moon, stars and darkness),The sections of Lail (Shafaq, Maghrib, etc. ), the functions of Lail (devotional, social, calendar, natural) and the semantic-conceptual types of Lail (complementary, intensifying, distributive and reciprocal) in the Qur'an were examined.

Every single word and sentence of eloquent words have been selected and arranged in a purposeful and logical way. The Quranic researchers have sought to discover the way of relation and the philosophy of the arrangement (order and formation) of the Qur'anic verses since the Quran is the most eloquent word. The process (semantic relations) is also defined in this way in order to provide a simple understanding of how the verses of the Qur'anic chapters are related. The content of each sura is divided into several semantic domains and the relationship between these relations is examined based on this new process. In this paper, the process (semantic relations) is adapted to the two suras (Arabic: سورة, chapters) of Ash-Shams (Arabic: الشمس) and al-Layl (Arabic: اللیل) in a descriptive analytical method to find an answer to the question of how the application of the process of semantic relations leads to the discovery of the textual coherence of Suras Ash-Shams and al-Layl. Finally, it is concluded that there is a central semantic relation in each of these two surahs that the rest of the relations are arranged in different methods of expressing in order to prove or believability and better understanding of that central meaning.

In the linguistics and semantics of the words of a text, it is important to analyze a set of words with the same meaning that are in a "semantic field" of that text. This linguistic approach, in better identification of a purposeful text such as the Holy Quran, is effective as the best example of rhetorical text and the most expensive literary text; Because the Qur'an has a frequency of words that are semantically convergent and related to each other and are in the same field of meaning. Undoubtedly, with different methods and approaches, including semantics, it is possible to understand some of the symbolic aspects of these words and the rhetoric of the Qur'an. Based on this, in the following research, with analytical-descriptive method, the words included in the field of meaning (mediational field) of extraction and the semantic relations between them have been examined and explained, and it has been found that: words that despite the difference in words in the field of meaning, describe the resurrection, are compatible with the name of this surah and its opening verses. Also, different words that are based on the relation of opposition (contradiction) in the same field of meaning, have a common meaning in describing the event of Qiyamah.

This research is a semantic study in Hatem Taei's poetry. After a brief look at the science of semantics and semantic domains and a brief look at Hatam's life, we studied every word in the semantic realm of forgiveness that either indicates the generosity of the poet or exists to gain the praise of God and people in his poetry. In examining all the words and combinations in this research, it is tried to deal with Hatam's poetry analytically, because the analysis can reveal to us the most accurate details of the issues, clarify the relationship between these words for us. This study intends to analyze the obvious or hidden relationships between these words by examining the semantics of Hatam's poetry. By extracting the words of this semantic domain, such as al-Bazal, al-Jud, Al-Khargh, Al-Ata, Al-Fazl, Al-Karam, Al-Nadi, Al-Naam, Al-Vahab, etc., and studying their semantic relations with other words, we performed a semantic analysis of Hatam Taei's poetry.

The breadth and scope of power of housewives is subject to limitations due to their fragile and vulnerable position in the economic and social structures. One of the areas on the basis of which women’s empowerment could be assessed is the decision-making process in everyday life. The purpose of this research is to semantically reconstruct the lived experience of married women of decision-making and explore the fields, consequences and ways of women’s exposure to the phenomenon of decision-making through the perception and mental conceptualization of the actions that women exploit in their everyday life a source of power to enhance their agency in the environment. The present study was carried out with a qualitative approach, couched in the grounded theory. Targeted sampling with maximum diversity was used to select the samples; and semi-structured interview was used to collect the data. The results of interview with 28 samples of Sanandaj women indicate that self-esteem, re-conceptualization and risk-taking, family support, gender stereotypes, experience (of decision making), and resources available to women, constitute the grounds for decision making of women. The semantic reconstruction of the experience and understanding of women of decision making shows that women appeal to such strategies as logical dialogue, due and timely fulfillment of responsibilities, financial independence and support, raising the expectations, and strike. The decision-making experience for women contributes to their sense of value, collective belonging, self-reliance, empowerment and self-esteem.

In this article, the difference between the meaning of the word Alaa and Nemat has been investigated. These two words are used in the Qur'an, but the translators also translated the word "Ala" as "Blessing". If we believe that every word in the Qur'an has its own meaning, there must be a difference in the meaning of these two words. Therefore, to understand the conceptual difference between these two words, we conducted this research. After examining the literal and interpretative meaning of these two words, it is understood that the word "Ala" tells the story of the peak of God's mercy and love, which is one of its examples. From this point of view, "Ala" is a blessing. Also, in blessing, the only consideration is the blessing itself from the material or spiritual aspect, external or internal and [...] But in "ala" in addition to its generality and including all types and examples of "nemat"; It also expresses the attribute of God's power. In the final part, the conceptual commonalities of blessing and blessing with grace, kindness, mercy and grace were pointed out and the difference in meaning of each was explained. This article has been written using library sources and analytical-descriptive method.

Structural semantics, based on Structural Linguistics, was affected by Ferdinand de Saussure's ideas which ensued many semantic studies. This approach explains the methodological study of meaning in the structure of text in terms of how linguistic units become meaningful. In this approach, the value of each linguistic unit is determined in relation to other linguistic units, and to examine the meaning of each unit, all relationships such as semantic contrast must be considered in semantic network analysis. The frequency of linguistic unit "Nazar" and its role in stylistic examination of Saadi's sonnets can show the significance of methodological study of these sonnets in relation to how the mentioned linguistic unit becomes meaningful. Excerpts from Saadi's sonnets provide us with a way to conduct a more detailed analysis of the semantic stylistics of Saadi's sonnets. This qualitative research explores the study of a literary text via a linguistic and stylistic method and aims to deal with the semantic implications of the "Nazar" unit in two semantic domains of love and mysticism and analyze it in a coherent semantic network.

Molecular epidemiology is relatively a new scientific field that explores the epidemiological aspects of diseases using molecular techniques. Genetic epidemiology is a branch of molecular epidemiology that explores the expression of genes and the interactions between genes and environment. Moreover, molecular epidemiology is one of the best methods to address some specific issues such as:1. Exploring how diseases such as HIV/AIDS had expanded among countries and in the world 2. Exploring the distribution of diseases in populations and tracking their transmission chains 3. Exploring the virulence of pathogens using molecular markers and linking their characteristics to the epidemiological indicators such as incidence and prevalence in this paper written for general practitioners and medical experts, the applications of molecular epidemiology in public health and medicine by unfolding simple and practical examples have been discussed.

In this article by using G-type domains, we introduce strong G-type domains and locally countable quotient rings (lcqr). Morover, G-type ideals are classified. Finally some relations between prime ideals and G-type ideals in valuation rings have been investigated.
