Mobile computing and technology are becoming more common in many parts of private life and public services, and they are playing an increasingly important role in healthcare, not just for sensory devices but also for communication, recording, and display. They are used for more than only sensory devices but also for communications, recording, and display. Numerous medical indications and postoperative days must be monitored carefully. As a result, the most recent development in Internet of Things- (IoT-) based healthcare communication has been embraced. The Internet of Things (IoT), which is employed in a wide range of applications, is a catalyst for the healthcare industry. Healthcare data is complicated, making it difficult to handle and evaluate in order to derive useful information for decision-making. On the other hand, data security is a vital requirement in a healthcare data systems. Determining the need for a smart and secure IoT platform for healthcare applications, we create one in this study. Here, a cutting-edge encryption algorithm is used to protect the health data. Normalization is first used to preprocess the data and remove any irrelevant information. Using principal component analysis and logistic regression, the data’s features are extracted (LR-PCA). To choose the pertinent features, a feature selection process based on genetic algorithms is used. We have put out a brand-new kernel homomorphism. To increase the security of the IoT network, use the two-fish Encryption algorithm (KHTEA). EBSMO (exponential Boolean spider monkey optimization) is used to further boost the encryption process’ effectiveness. Utilizing the MATLAB simulation tool, the proposed system is assessed, and the metrics are contrasted with the accepted practices. Our suggested solution has been shown to be effective in protecting medical healthcare data. The effectiveness of the proposed and existing approaches is assessed using metrics for encryption time, execution time, and security level. The security precautions we suggested for healthcare data worked well.

Distillery industry is an important segment of world economy. However, a large amount of waste water generates during the alcohol production. This waste water contains very high organic load (COD ∼ 9080). Pollution regulatory agencies are very strict to maintain the standards of pollutants in treated effluent before the discharge in any water receiving body. In this context, combined technologies are very effective to manage dischargeable limit as compared to stand alone treatment process. This work is an attempt to treat distillery industry wastewater with electrochemical and chemical process by using iron as electrode. Electrochemical treatment has provided 91% chemical oxygen demand and 71.5% color reduction at pH 7, electrode gap 20 mm, current density 26 mA/cm2 and 70 min of reaction time. Whereas, in combined process of treatment maximum 97% (24.51 mg/dm3) COD reduction and 92.6 % (10.79 PCU) color reduction were achieved at mass loading of 1 g/dm3 and pH 7 with ferrous sulphate.

BACKGROUND: In recent years, a lot of research work has been done to transmit vital parameters of the patient usingIOT (Internet of Things). The information related to Patient is sent by means of WBAN (Wireless Body Area Network)and sensors to the healthcare database. This has been shown a great potential to transmit vital parameter of the patient at aremote location. Remote monitoring of patient(s), including vital signs, sound and video is to be transmitted, particularlywhen a patient is in transit. By transmitting the imperative parameters of the patient to a specialist diminishes, the idealopportunity for starting treatment and permits the emergency crew to be better prepared. This will facilitate a doctor tomake a diagnostic conclusion.OBJECTIVES: This study aims to develop an advance system to transmit the vital parameters of the patient to the smartphone of the doctor at a remote location. After seeing essential parameters of the patient, the specialist can convey/endorsethe medication from the remote area.METHODS: To monitor patient’s data in real-time an android application is developed which helps the medical staff tomonitor the patient from remote location. All the patient related information is stored in Real Time Clinical Database.RESULTS: The proposed model will allow the doctors to monitor physiological parameters (HR, NIBP, Temp, ECG,SPO2) of the patient, as well as endorse medication from the remote location. This system will be helpful to providevirtual presence of the doctor inside the ambulance and to provide lifesaving drugs to the patient while the patient is intransit.CONCLUSION: The present invention provides a fully integrated system for the doctor to view the vital signs of thepatient from the remote location in real-time.
