A modified bow-tie dipole antenna fed by a 50 coaxial cable is proposed for dual band operations. By asymmetrically cutting the lateral sides of the conventional bow-tie dipole antenna results in two operating frequencies at 915 MHz and 2.45 GHz. The main attraction of this novel antenna is improved band width with a considerable antenna size reduction for dual band operation particularly in RFID bands. Simulated results with CST microwave Studio are presented along with measured results and good agreement between them is obtained. © 2015 IEEE.

This paper deals with the recognition of handwritten Malayalam characters. Most of the pattern recognition systems will go through the steps like preprocessing, feature extraction and classification. Here, we have presented edge detection in the preprocessing stage. It is important that the edge detector should give the character edges without fragmentation and displacement of edge pixels. Canny edge detector is used to produce thinned edges of the character. But for high resolution images, it gives spurious branches corresponding to noise and texture of the image. So a technique is applied prior to this process to focus the edge regions using nonlinear anisotropic diffusion via partial differential equations (PDE). Even though this method helped to get accurate edge points, the final result shows some broken edges. These broken parts are then linked using ant colony optimization (ACO) method. This image is further partitioned into different zones for the purpose of feature extraction. Multi layer perceptron (MLP) used these features and classified the characters with a recognition accuracy of 95.16%. © 2010 IEEE.

Coronary heart disease (CHD) is epidemic in India and one of the major causes of disease-burden and deaths. As a chronic disease it may confront a patient with numerous threats and challenges. Several studies have shown that identifying resilient factors are important in the psychosocial management of the patients. The aim of the study was to identify cognitions about illness, self efficacy and its relation to anxiety and depression. Sample consisted of 43 CHD patients 22 in Group 1(diagnosed within 3 months) 21 in Group2 (diagnosed more than 3 mths -up to 1yr).Results shows that both groups showed significant statistical difference in many dimensions. Helplessness was more in Group 2. Also anxiety and depression was slightly more in Group 2.Compared to Group 2, for Group1 there was significant negative correlation between acceptance, perceived benefits and self efficacy with anxiety and depression. This study has implication for enhancing resilient factors in order to enhance the psychological management in case of life style disorders.

Preoperative Anxiety is an important problem involving patients who are about to undergo surgery. Patients may perceive the day of surgery as the biggest and the most threatening day in their lives. The degree to which each patient manifests anxiety related to future experiences depends on many factors. Apart from other surgeries caesarean section is associated with a positive outcome. The current study aims to find out whether there is any significant difference in hospital anxiety, depression and psychological well being among women undergoing caesarean section and general surgical procedures. The study was conducted among 30 women posted for caesarean section and 30 women posted for general surgeries. It was found out that hospital anxiety and depression was significantly higher in patients who underwent general surgical procedure that caesarean. General psychological well being was significantly higher in patients who underwent caesarean, compared to the other group.

Acne and eczema are common skin disorders with a significant psychological and social impact for female adolescents and young adults. The present study was conducted to evaluate quality of life, perceived social support and self efficacy of patients with acne and eczema. A study was done in which data collected from dermatology department of Amala Institute of Medical Sciences which comprises 56 females aged 16-25yrs. 30 of them were suffering from severe acne and 26 of them were suffering from chronic eczema. Dermatology Life Quality Index, The General Self Efficacy Scale, Multidimensional Scale for Perceived Social Support was the major measures used. Findings from the present study show that Greater quality of life was associated with high self efficacy for females with eczema. There were positive relationship between self efficacy and perceived social support on quality of life in acne and eczema patients. Acne and eczema significantly affects quality of life of patients especially when they are affected during adolescent and early adulthood period of life. Along with pharmacological management, enhancement of self efficacy and social support through psychotherapeutic interventions may benefit them to enhance quality of life and in turn better adjust in future life.

An unwed mother is a girl or woman who is not legally married to a man by whom she has conceived a child. Research indicates that single mothers experience excessive stress and that the stress is a result of various factors like of social isolation, lack of family support, the need to provide financially for the family. The purpose of this study was to assess the psychological wellbeing of unwed mothers in comparison with wed mothers. The first objective was to find out the level of depression among wed and unwed mothers. The study is also aimed to find out the different dimensions of social support of wed and unwed mothers and the relationship among the level of depression, and social support in wed and unwed mothers. The sample for the present study consisted of two groups: wed mothers and unwed mothers. The wed and unwed mothers are comprised of 30 each between the ages of 20-35 years. Tools used were Beck depression inventory (BDI-II) and the multidimensional scale oferceived social support. To know the difference between the wed and unwed t-test was administered. Pearson product-moment correlation coefficient was administered to know the correlation between the depression level and different dimensions of social support. Result reveals that there is much higher depression level in the unwed mothers. 36.66% of the unwed mothers were found to have severe depression where as none of the wed mothers had the same. Social support from the significant other, family and friends were found to be lower in the unwed mothers compared to wed mothers. The result shows that a very high negative correlation is obtained in different dimensions of social support and depression, indicating that when the social support decreases the level of depression increases.

A modified bow-tie antenna, which finds potential use in Radio Frequency Identification (RFID) / Industrial, Scientific and Medical (ISM) applications, is proposed. Triple band operation is facilitated by applying trapezoidal truncations on both arms of the bow-tie antenna. The major attractive feature of the proposed antenna is its improved bandwidth for triple band operation particularly in different RFID bands. A considerable size reduction of the patch area is also achieved for the proposed structure. The simulated results for the return loss characteristics are in good agreement with the measured results. © 2016 The Authors. Published by Elsevier B.V.

How the children with handicap perceive themselves and their self esteem levels are important yet not much focussed aspect in disability research. If we have a correct evaluation of their motivational level and self esteem it may help us to modify their training interventions and also would make them feel more satisfied and confident. So we planned to study achievement motivation and self esteem levels of handicapped children. The Objective of the study is that to to compare achievement motivation of physically handicapped to that of non-handicapped school children, and to compare self esteem of physically handicapped to that of non-handicapped school children. Methodology 40 physically handicapped school students and 40 age, gender and education matched non handicapped students were included in the study. Handicapped children of other categories like sensory disability, visual impairment, hearing impairment and speech impairment were excluded. Achievement motivation questionnaire was used to measure the motivational behaviour and Rosenberg self-esteem scale was applied by asking the respondents to reflect on their current feelings. Results and Conclusions Achievement motivation and self esteem were observed to be significantly lower in physically handicapped students compared to healthy controls. Significant gender difference in favour of females was observed i.e., self esteem and achievement motivation was significantly higher in females of both the groups compared to males. The study emphasizes need for interventions to improve self esteem and motivation levels of handicapped children.
