A bstract Background Incontinence-associated dermatitis (IAD) is a potentially serious skin injury that can lead to pressure ulcers (PUs). Many studies have indicated the need for evidence to find the most effective skin care protocol to reduce the incidence and severity of IAD in critically ill patients. Aim and objective To develop a need-based interventional skin care protocol on IAD after identifying the risk of developing IAD in critically ill patients and by assessing the nurse's knowledge and practice on IAD. Materials and methods Quantitative research approach with an exploratory research design was adopted in the study. A total of 40 staff nurses and 100 patients were included. To assess the knowledge of staff nurses regarding IAD, a knowledge questionnaire was administered and the IAD prevention practice among staff nurses was assessed with the help of an observation checklist. The risk of IAD among 100 critically ill patients was observed by the investigator, using a perineal risk assessment tool. The obtained data were analyzed by using descriptive and inferential statistics. The protocol was developed by the researcher and it was validated by 5 experts. Results The results revealed that most of patients (60%) had a high risk for development of IAD. Most of the nurses had poor knowledge (40%) and had poor practice in assessment, perineal area, and prevention of infection area. Hence considering all these aspects, a protocol was developed. Conclusion The researchers developed a need-based skin care protocol to decrease the development of IAD. How to cite this article Sharma P, Latha S, Sharma RK.

Wireless sensor networks consist of a network of autonomous sensors that can reconfigure themselves so as to sense the environment in the most significant manner. However, a significant challenge in the practical application of these networks exists in credible authentication and network security. This paper proposes a secure authentication protocol which is considered as a pro-active method, where a user is strongly verified before accessing the data, it is the modified Adhoc On-Demand Distance vector (AODV) Routing protocol that provides many security principles to the user such as checking sequence number, IP address and threshold values. The performance of proposed algorithm is compared with the existing alogorithm based on the following parameters such as Throughput, End to End delay and packet delivery ratio. The results shows that the proposed protocol possesses many advantages against the popular black hole attack. This work has been carried out using NS2 software and the result obtained testifies the effectiveness of the proposed protocol.
