Abstract: Importance: This post-marketing surveillance study was conducted to evaluate real-world information about the efficacy and safety of oral Tinefcon? tablets (Sphaeranthus indicus based) in plaque psoriasis patients. Materials and Methods: Patients aged at least 18 years and older with clinical diagnosis of plaque psoriasis, were enrolled in this open label, non-comparative, multicenter trial. All eligible subjects received four 700 mg Tinefcon? tablets/day for 12 weeks. The primary outcome measure was percent change in Psoriasis Area Severity Index (PASI) score from baseline to week 12. The secondary outcome measures were Physician Global Assessment (PGA), Nail Psoriasis Severity Index (NAPSI), Psoriatic Arthritis Evaluation and Gene Expression Profiling and Immunohistochemistry. Results: After completion of Tinefcon? treatment at 12 weeks, more than half of subjects (52%) achieved PASI 50 response; PASI 75 response was attained in 68 (23%) subjects and PASI 90 response in 22 (7%) subjects. Five subjects with severe psoriasis achieved PASI 90 without receiving any concomitant medication. Reduction in severity as assessed by PGA was observed in more than half of patients with moderate disease. Histopathological evaluation revealed that epidermal thickness was considerably reduced in 66% of subjects. The expression of inflammatory marker S100A9 protein was(meaningfully reduced in 60% patients with non-significant reduction of Keratin 10 protein expression. Gene expression analysis showed increase down regulation of SERPINB4; PI3 and KRT16 genes after a 12-week treatment period in subjects with higher PASI scores. Conclusion: Oral Tinefcon? tablets showed good efficacy and had a

Abstract: Student Response Systems (Clickers) have been adopted by a number of instructors to increase interactions, student engagement and/or formative assessment and feedback especially in large group sessions. Clickers are well known as tools for active learning strategy particularly in formative assessments. However, they are rarely used in assessments that count. With the advent of clickers with a display screen, attempts are being made to use clickers in summative exams. We examined the feasibility of their use in high stakes summative assessment by piloting such an assessment in a simulated setting. Utilizing the lessons learned in the pilot study, clickers were used in formative and summative assessments in various iterations of a computer course taught by one of the authors (CC). At the end of the course, perceptions of students on the use of clickers for high-stake examinations were obtained using an online survey. The instructor was interviewed to identify factors that facilitated clicker use and the challenges faced. In general, students were accepting of the use of this technology in high stakes exams and found it engaging and satisfying, primarily because of instant feedback. The instructor found the process less time consuming and efficient, and more secure compared to scan sheets. Clickers are best used for examinations of short duration, with multiple-choice questions or questions with minimal text or mathematical entry.

Abstract: Because of the low maintenance and robustness induction motors have many applications in the industries. Most of these applications need fast and smart speed control system. This paper introduces a smart speed control system for induction motor using fuzzy logic controller. Induction motor is modeled in synchronous reference frame in terms of dq form. The speed control of induction motor is the main issue achieves maximum torque and efficiency. Two speed control techniques, Scalar Control and Indirect Field Oriented Control are used to compare the performance of the control system with fuzzy logic controller. Indirect field oriented control technique with fuzzy logic controller provides better speed control of induction motor especially with high dynamic disturbances. The model is carried out using Matlab/Simulink computer package. The simulation results show the superiority of the fuzzy logic controller in controlling three-phase induction motor with indirect field oriented control technique.

Abstract: Recent research work in the Wireless Sensor Networks involves the homogeneous networks in which the sensor nodes in the specific cluster can get the key value from any other cluster. Most existing key management schemes try to establish shared keys for all pairs of neighbor sensors, no matter whether these nodes communicate with each other or not, and this causes large overhead . The security implementation analysis is separated into two levels, 1. Encryption and Authentication from Sensor modes to Cluster Head. 2. Encryption and Authentication from Cluster Heads to Base Station. This Dual level Encryption standards not only blocks the malicious data fromoverspreading the network traffic all along the network path but also efficiently shares the dynamic keys. In this research the second level of security has considered and the dynamic keys are generated based on pass pattern or graphical picture. Here dynamic means both 1). The display and selection of characters from a 7x7 matrix calledpattern square changes in every session and 2). The strength and degree of security changes dynamically. This pattern consists of a set of symbols such as special characters, alphabets, numbers, etc. by default. The character entered by the user is subjected to the first level of encryption. The encrypted string is placed in 5x5 matrix called magic square. The second level of encryption applied to the pattern value and finally stored in the database in row major. The pass pattern is selected from the pattern square characters which are randomly displayed for each session. This random change in display of characters leads to higher level of security. Also the user is allowed to select their pattern in reverse order which ensures more degree of security against the attack by crackers. This method is strong and robust against all possible attacks and works in the existing infrastructure without compromising the user’s comfort.

Abstract: Background: Fluorosis is one of the common but major emerging areas of research in the tropics. It is considered endemic in 17 states of India. However, the Cuddalore district of Tamil Nadu is categorised as a fluorosis non-endemic area. But clinical cases of dental fluorosis were reported in the field practice area of Department of Community Medicine, Rajah Muthiah Medical College, Annamalai University, Chidambaram. Since dental fluorosis has been described as a biomarker of exposure to fluoride, we assessed the prevalence and severity of dental fluorosis among primary school children in the service area. Materials and Methods: Children studying in six primary schools of six villages in the field practice area of Rural Health Centre of Faculty of Medicine, Annamalai University, Chidambaram, were surveyed. Every child was clinically examined at the school by calibrated examiners with Dean′s fluorosis index recommended by WHO (1997). Chi-square test, Chi-square trend test and Spearman′s rank correlation coefficient test were used for statistical analysis. Results: Five hundred and twenty-five 5- to 12-year-old school children (255 boys and 270 girls) were surveyed. The overall dental fluorosis prevalence was found to be 31.4% in our study sample. Dental fluorosis increased with age P < 0.001, whereas gender difference was not statistically significant. Aesthetically objectionable dental fluorosis was found in 2.1% of the sample. Villages Senjicherry, Keezhaperambai and Kanagarapattu revealed a community fluorosis index (CFI) score of 0.43, 0.54 and 0.54 with 5.6%, 4.8% and 1.4% of objectionable dental fluorosis, respectively. Correlation between water fluoride content and CFI values in four villages was noted to be positively significant. Conclusion: Three out of six villages studied were in ′borderline′ public health significance (CFI score 0.4-0.6). A well-designed epidemiological investigation can be undertaken to evaluate the risk factors associated with the condition in the study region.

Abstract: This study was undertaken to identify occupation related skin problems among hotel workers. One thousand three hindered and ninety employees of a chain of vegetarian hotels were examined. Of the 273 people working in the kitchen, 206 (75.4%) had dermatosis related to work. The Kitchen workers were classified according to the type of work they routinely performed. Forty eight out of the 63 (76.1%) cooks who were involved in stirring had callosity at sites of contact with ladle and 28 of the40 (70%) cooks who were involved in frying had pigmentation and scars due to contact with hot oil and water. All the onion peelers had staining and fissuring of the palmer aspect of the fingers. Thirty two of the 46(69.5%) vegetable cutters had callosity on the palm at areas of contact with knife. Poori markers had pigmentation and callosity of knuckles due to pressing the dough with their knuckles. Nine of the 12 (66%) rice cleaners had chapping of nails. Seven of the 12 (58.3%) paratha markers had erythema of palm due to contact with hot tava. Tandoori experts had singing of hair over right forearm. Two workers (0.73%) had pigmentation of the face probably due to prolonged exposure to heat. Two of the16 (12.5%) grinders had paronychia and onychomycosis due to constant contact with water and dough. Nine of the 15 (60%) coconut graters had callosities of the palms. We conclude the minor occupational dermatosis is prevalent among kitchen workers employed in hotels
