Prevalence and Pattern of Consanguineous Marriages Among Different Communities in Mangalore

Introduction: Consanguineous marriages are a common practice in the Middle East, Asian and African populations. Many studies have stated an association between first cousin marriages and the incidence of autosomal recessive diseases and congenital malformations. High frequency of consanguinity is reported by researchers among South India. The objectives of this study were to determine the prevalence and type of consanguineous marriages among the different communities of Mangalore. Methods: This study was conducted on 1164 married women in Mangalore to investigate the prevalence and type of consanguineous marriages. All the women were interviewed personally using a structured questionnaire. Family pedigree was constructed to study the type of consanguineous marriages. Data analysis was done by SPSS Win 13.0. Results: A low percentage of consanguinity (6.53%) was observed with a mean inbreeding coefficient of 0.0339. Frequency of consanguinity between religions was highly significant. Of these the most frequent were first cousin marriages (43.42%). Within Hindu religion the highest rate of consanguinity was among the Billavas (47.62%) of which the most frequent were distant relative marriages (75%) followed by second cousin marriages (57.14%). There was no significant difference in the frequency distribution of the types of consanguinity between the religions and also between the different groups among Hindus. Conclusion: The frequency of consanguinity was found to be low in Mangalore. The findings contradict with the earlier reports of high prevalence of consanguineous marriages in South India. Increased female education, increased socio-economic status and decrease in parental decisions in marriages may be the reasons

Computational aspects of a three dimensional non-intrusive particle motion tracking system

Development of a technique for non-intrusive particle motion tracking in three dimensions is considered. This technique is based on the principle of magnetic induction. In particular, the determination of the position and onentation of the particle from the information gathered is the pnncipal focus of this thesis. The development of such a system is motivated by the need to understand the flow patterns of granular material. This is of cntical importance in dealing with problems associated with bulk solids flows which occur in almost all industries and in natural geological events. A study of the current diagnostic techniques reveals the limitations in their ability to track the motion of an individual particle in a mass flow of other particles. These techniques fail when the particle must be tracked in three dimensions in a non-intrusive manner. The diagnostic technique we consider results in an unconstrained minimization problem of an overdetennined system of nonlinear equations. The Levenberg-Marquardt algorithm is used to solve such a system to predict the location of the particle. The viability of this technique is established through simulated and actual expenmental results. Practical problems such as the effect of noise are considered. Directions for future work are provided

A Novel Approach to Communicate Secret Message Between Users Using Sponge Function Technique on NTRU

This paper presents a novel approach for a (key distribution) for secret message communication among a group (G). In order to increase security to distribute secret message (key), we introduce sponge functions using these at a specific permutation. We generate a key and distribute this key using (PKCS)(public key crypto systems), the absorbing, squeezing functions are used. In this paper an introduction part which briefs regarding sponge functions, key distribution centre, group communication and NTRU, key generation authentication, in literature review we describe about the research states of sponge functions, lightweight hash functions-KDC – NTRU. In proposed work we propose how the group communication establishes registration of users, entry and exit of a user. The encryption and decryption algorithm are used between sender and receiver. The entire proposed work is verified in VHDL and ‘MATLABS'. doi: http://dx.doi.org/10.12777/ijse.4.2.2013.44-51 [How to cite this article: Varaprasad, S., Rao, K. V., & Avadhani, P. S. (2013).

Study of craniofacial skeletal patterns and body measurements in south Indians

Introduction:Craniofacial skeletal pattern and body measurements have been studied in anthropology, orthodontics, cosmetology and garment industries. The purpose of this study was to find the relationship between craniofacial skeletal pattern and body measurements, Ratios and BMI. Methods: Digital lateral cephalogram was recorded for all the two hundred subjects and were traced and analysed using six cephalometric measurements to identify craniofacial skeletal pattern. These two hundred subjects were divided into three groups Vertical, Horizontal and Average. Then twenty five subjects from each group were randomly selected for this study. Each subject’s height, weight, chest, waist and hip were measured and the ratios and BMI were derived. Data was tabulated and statistically analysed. Results: Waist measurement showed significant difference between Vertical and Horizontal groups.  The body mass index showed significant differences between Vertical and Average group. However, there were no significant differences in any measurements taken between Horizontal and Average. Conclusion: The data recorded by the present study shows that waist and BMI are significantly associated with each other between three groups. We would like to conclude by suggesting that these data can be used in identifying the craniofacial skeletal patterns in early age and preventive methods can be used in cardiovascular risk factors. Additionally these results can be used by forensic anthropologists as well as fashion designers to correlate the ratio and craniofacial skeletal patterns.  &nbsp
