Background Appropriate mammary positioning is an important factor in optimizing image quality in mammography (MMG). Purpose To study the correlation of quality criteria and breast density classification proposed by the American College of Radiology (ACR) and European Guidelines and its influence to achieve a proper positioning, therefore an adequate MMG. Material and methods A total of 128 routine MMG examinations were reviewed for the definition of breast composition parenchyma and assessment of several quality criteria proposed by the ACR and European Guidelines to achieve an adequate MMG. Adequate MMG was defined as a difference between the posterior nipple line (PNL), difference of the mediolateral oblique (MLO) and craniocaudal (CC) incidences > 1 cm. The quality criteria were analyzed as a function of correlation coefficient in order to evaluate the individual impact of each factor and analysis of variance (ANOVA) for all criteria. Receiver operating characteristic (ROC) curves were plotted to evaluate the performance of the criteria on each type of parenchyma. Results Negative correlation of fatty breasts and visibility of the mammary angle, a greater number of skin folds and PNL > 1 cm (r < 0). Dense MMG presented less visibility of the lateral tissue compared with other categories. Area under the curve of ROC analysis revealed values of 53.1% and 54.7% for the right and left breasts, respectively. Conclusion Several factors influenced in the MMG process, but we find that breast parenchyma has a substantial role in affecting these criteria and therefore a correct position for diagnosis, which could compromise MMG diagnostic performance.

The Impact

<p>Settling in the cities and the numerous efforts being made for massive supply of houses in a short time period, makes difficult the access to a pattern as appropriate for family life with increase in concentration in building construction, the individual and family borders, too, are neglected.</p><p>Though due to the extensiveness and complexity of the concept of housing, one cannot give a comprehensive, unique definition of it, but the housing, as a shelter, is regarded as the primary and basic needs of the family.</p><p>House as a place for relaxation and comfort and a shelter for removing tiredness has been a peace and security locality from a long time ago. House demand is one of the most essential human`s demands. According to Article 31 of fundamental law of Islamic Republic of Iran also, possessing a suitable house is considered as the right for every person and every Iranian family. House not only as a shelter, but also as a place for humans raise, has a great importance in the initial and most fundamental society union, namely family.</p><p>Identifying the identity and investigating the residential complexes in regard to the aesthetics implies the precise and conscious observing and noticing their beauties and or ugliness.</p><p>Main Questions in this paper are:</p><ul><li>What are the consequences of disregarding the identity of today's housing architecture, especially the architecture of the ancient towns?</li><li>Can the components of Iranian traditional architecture be applied in today contemporary residential architecture and be effective to create a sense of place?</li></ul><p>So the main purpose of this article is Pathology of Today Contemporary Iranian housing Architecture and Comparison with traditional Iranian architecture.</p><p>The method explored is a descriptive-analytical and field method to gather information and documents are available. The impact of known factors and variables in Iranian contemporary and traditional residential architecture has been evaluated and compared.</p><p>Accordingly, having some criteria for achieving a suitable house design pattern is essential in a way that makes it possible to understand all its visual embodiments and identify its identity.</p>This research also state the reasons for disability of today`s architecture and urban development against house problem and recommend some criteria for achieving a house design pattern after an overview of the definition of housing and examination of Iranian housing.

The Right

The right to life is the highest value, is the basis of all other human rights and freedoms, but Russian legislation does not contain a definition of a person's life. In legal science, the right to life is interpreted as the right of the individual to freedom and personal integrity, health protection, reducing the problem to the abolition of the death penalty and euthanasia. The article deals with issues that are especially relevant in connection with the development of artificial methods of reproduction: from when does the right to life arise and whether the embryo has a legal value.

Abstract The Asylum Procedures Directive stipulates that asylum applications are examined ‘impartially’ by the national authorities. This paper explores the meaning of the term impartiality in administrative settings in EU asylum law focussing on three levels: the Common European Asylum System, the administrative organisational level and the level of the individual immigration officer. CEAS does not provide for a definition of impartiality. The article connects impartiality to the right to good administration as in the Charter of Fundamental Rights of the EU. It includes jurisprudence of the Court of Justice of the European Union and the European Court of Human Rights as well as the approach of the EU Ombudsman and EASO in its scope. These sources provide more concrete aspects of impartiality. The article is finalized with recommendations for a code of conduct.
