Introduction. The article deals with the main traditional outbuildings of the Mordvinians, reported on their functional purpose in economic activity. The forms and types of outbuildings, as well as the main building materials used by Mordvinians are described in details. Their significance in the religious and ceremonial life of the ethnic group is shown. Materials and Methods. The research is based on traditional methods of ethnographic science, such as field observation, survey and interviews, and a comprehensive approach. Among the methods of historical science comparative-historical, historical-genetic, problem-chronological, structural-system were used. Among the general scientific methods of research logical, descriptive, narrative, generalization, classification and systematization were involved. To achieve the results of the study, the materials collected by the authors in the course of field surveys conducted in the Mordovian villages were mainly used. Results and Discussion. Traditional outbuildings were of great importance in the economic activity of the Mordovian ethnic group. According to their functional purpose, they can be divided into the following groups: for livestock and poultry (stable, chicken coop, stable, kalda), sanitary and hygienic (bath), warehouse buildings for storage of food, utensils, firewood, animal feed (barn, cellar, woodshed, hayloft), for processing of grain (sheep, riga, mill). Depending on the welfare and financial capacity of the family, the number of outbuildings was different. As a rule, the wealthier families had more outbuildings than the less wealthier ones. The main building material for the construction of these buildings was wood. Conclusion. Thus, the traditional outbuildings of the Mordvinians occupied an important place in its economic activities. At the same time, each of them had its own purpose and performed certain functions. Some buildings, such as a bath and a barn, had not only economic purpose, but also were the venue for a number of prayers and ceremonies. It is now ordinarily they have banya (bath-house), outdoor courtyard with standing in different places sheds, barn and cellar.

The conceptions about stuttering vary amongst cultures. Culturally specific findings regarding stuttering help in understanding the peoples' views and conceptions about stuttering and devising awareness and counselling strategies. A total of 132 passengers on the Coromandal Express from Chennai to Howrah participated in this study. All of them belonged to the upper middle socio-economic class. Preliminary Stuttering Conception Questionnaire (PSCQ) was used to understand their conceptions of stuttering. 23% had no idea and 12% had myths about the etiology of stuttering. 11% assumed it was a genetic problem and 5—6% a physical-mental problem. 31% had no idea of treatment options. 25% preferred medicine, 23% rehabilitation for treatment of stuttering. For rehabilitation, only 45% precisely knew about the speech language pathologist; the remaining 55% were unaware of this profession. Steps need to be taken towards educating the common man about stuttering.

Genetic Problem

Background: Turner syndrome occurs in nearly one in every 2000-5000 female births. This syndrome is a genetic problem in the female phenotype and the most common sex chromosome anomaly. It is diagnosed based on clinical manifestations and cytogenetic examinations. The classic syndrome (i.e., monosomy X) makes up 50% of the cases while other forms contain X chromosome variants, which do not typically manifest as the classic X phenotype. Case Presentation: This study, presents a rare variant of Turner syndrome reported in a 20-year-old woman presenting with primary amenorrhea, hypothyroidism, and short stature who had hypergonadotropic hypogonadism with hypoplastic ovaries while without the clinical manifestations of the classic Turner syndrome. The karyotype was determined as X isochromosome-X syndrome [46 XXi (Xq)]. Conclusion: This rare syndrome occurs in approximately 7% of the cases of Turner syndrome. Rare variants of the syndrome should also be considered in female patients without the classic manifestations of Turner syndrome.

Genetic Problem

Subacute combined degeneration (SCD) is a metabolic disease caused by deficiency of vitamin B12. Rarely, it could be associated with genetic problem. An old male presented with progressive both hands weakness. Laboratory study showed deficiency of vitamin B12, but the cause was not clear. We performed a genetic study and methylenetetrahydrofolate reductase (MTHFR) C677T homozygous polymorphism with 30% of normal enzyme activity was confirmed. This case suggests SCD may occur in association with a genetic problem with MTHFR C677T polymorphism.

Fertility Traits

National dairy records have shown that correlations between production and fertility are generally unfavourable. There has therefore been a genetic downward trend for fertility due to the increase selection pressure on yield and as a genetic problem it requires a genetic solution. The effect of sire genetics on daughter fertility is included in many genetic indices around the world. As part of a DEFRA LINK project to produce an UK fertility index this study estimates genetic parameters and sire predicted transmitting ability (PTAs) for fertility traits in the UK.
