Facial Expression is one of the most natural, and powerful means for human beings to Communicate their emotions and intentions. The recognition of facial expressions is very important for interactive Human Computer Interfaces. One crucial step for facial expression recognition (FER) is the accurate extraction of emotional features. Numerous feature extraction techniques have been developed for recognition of expressions from static images as well as videos. This paper put forward an approach using distance features that are obtained by extracting patch based 3D Gabor features and conducting patch matching operations. The experimental results shows high correct recognition rate (CRR), fast processing time and significant performance improvements because of the consideration of facial components and muscle movements. Comparison with the state-of-the art indicates that the proposed approach achieves high CRR for JAFFE database and is one among the top performers on the Cohn-Kanade (CK) database.

Introduction: Probiotics are microbes that positively influence health an individual when ingested in appropriate quantities. This study is done to assess the variation in salivary buffering capacity and salivary pH in moderate gingivitis patients before and after probiotic intake. Aim and Objective: To assess the role of probiotics on buffering capacity and salivary pH. To study the effect of probiotics in controlling gingivitis. Methodology: A study group of 10 subjects between the age group of 25 - 35 years with moderate gingivitis. Gingival Index was recorded. pH and buffering capacity of the saliva is determined using GC saliva buffer kit before and after probiotic intake. Results: There was significant improvement in gingival health after 14 days consumption of probiotic yogurt. However, there is no significant difference between gingival index, buffering capacity and pH before and after probiotic consumption. Conclusion: There was significant improvement in gingival health after 14 days consumption of probiotic yogurt. Long term research and clinical trials are required to reveal whether the probiotics can be used for preventing or treating oral diseases.

Background: Adverse events results in unintended harm to the patients including permanent disability and death. MEWS was introduced to identify and document the deteriorating patients in hospital settings. Adequate training and education of nurses will enhance early recognition and response in preventing adverse events. Objective: The objective of the study was to assess the effectiveness of competency training program on MEWS among nurses. Methodology: A Quasi experimental study was conducted among nurses who were working in inpatient units of selected hospitals, Chennai. 140 nurses were selected as participants out of which (n=70) is constituted to experimental group and (n=70) was constituted to control group. Pre-test knowledge was assessed in both groups. Competency training program on MEWS was given to experimental group of nurses and post test was assessed after one month. Results: The mean post-test knowledge scores was significantly higher in experimental group (M=18.2) to that of control group (M=10.6) which shows the effectiveness of competency training program on MEWS with (t=22.29, p less than 0.001). Conclusion: The present study reveals that Competency training program on MEWS had a significant increase in the knowledge of nurses in the experimental group.
