The Internet of Things (IoT) and Cloud computing are gaining popularity due to their numerous advantages, including the efficient utilization of internetand computing resources. In recent years, many more IoT applications have beenextensively used. For instance, Healthcare applications execute computations utilizing the user’s private data stored on cloud servers. However, the main obstaclesfaced by the extensive acceptance and usage of these emerging technologies aresecurity and privacy. Moreover, many healthcare data management system applications have emerged, offering solutions for distinct circumstances. But still, theexisting system has issues with specific security issues, privacy-preserving rate,information loss, etc. Hence, the overall system performance is reduced significantly. A unique blockchain-based technique is proposed to improve anonymityin terms of data access and data privacy to overcome the above-mentioned ***, the registration phase is done for the device and the user. After that, theGeo-Location and IP Address values collected during registration are convertedinto Hash values using Adler 32 hashing algorithm, and the private and publickeys are generated using the key generation centre. Then the authentication is performed through login. The user then submits a request to the blockchain server,which redirects the request to the associated IoT device in order to obtain thesensed IoT data. The detected data is anonymized in the device and stored inthe cloud server using the Linear Scaling based Rider Optimization algorithmwith integrated kL Anonymity (LSR-kLA) approach. After that, the Time-stamp-based Public and Private key Schnorr Signature (TSPP-SS) mechanismis used to permit the authorized user to access the data, and the blockchain servertracks the entire transaction. The experimental findings showed that the proposedLSR-kLA and TSPP-SS technique provides better performance in terms of higherprivacy-preserving rate, lower info

Correlations between estrogenic activity and DOC/UV260 ratio in wastewater treatment processes were investigated to propose a simple, reliable and comprehensive indicator for the presence of estrogenic substances. Contrary to this, when short-term bioassays such as the E-SCREEN, receptor binding and reporter gene expression assays are used for detecting estrogenic activity in the wastewater sample, they require a long time, at least a few days. The major factors contributing to the estrogenic activity were found to be 17β-estradiol （E2） and estrone （El）. A good relationship between the DOC/ UV260 ratio and the concentration of estrogens （El and E2） in the effluent of the activated sludge process was found： the E2 concentration increased as the DOC/UV260 ratio increased while the E1 concentration decreased. The relative estrogenic activity and DOC/UV260 ratio showed a good correlation （R^2 = 0.84） for all sewage samples except the ozonized samples in the sewage treatment plants. This study shows that the estrogenic compounds are hard to be mineralized by the conventional biological processes. Advanced oxidation processes are required to further remove estrogenic substances in the secondary effluent. By analysis of DOC and UV260, the estrogenic activity in the wastewater can be rapidly estimated.

Software development teams communicate differently by using a variety of communication tools. Successful communication leads to competitive software based on clear and quickly delivered re-quirements, as well as smoothness in bug reporting and explanation. Agile and Waterfall software development approaches have both addressed the importance of communication for their process. However, neither Agile nor Waterfall has guaranteed communication effectiveness during their development lifecycle. In this study we highlight the main differences between Agile and Waterfall approaches in the light of Media Richness Theory (MRT). We also identify the preferred commu-nication tools during a project’s lifecycle using both Agile and Waterfall models separately. A mixed-method approach was employed in this study incorporating quantitative and qualitative data from interviews and a multilingual web-based survey. The results are presented descriptively and statistically and a rank ordering of communication tools based on our participants’ preferences leads to a better understanding of how to select the best tool in a given situation. Thus a new updated MRT ranking model tailored for software development environment was developed, as well as, we conclude that communication tools are employed differently based on project stages and team member’s role. These differences in using communication tools could be also attributed to the type of transferable information or personal preferences.
