Digitisation of research data is widely increasing all around the world because it needs more and development of enormous digital technologies. Data curation services are starting to offer many libraries. Research data curation is the collective invaluable and reusable information of the researchers. Collected data preservation is more important. The majority of the higher education institutes preserved the research data for their students and researchers. It is stored for a long time using various formats. It is called research data preservation. Without proper research data management plan and implementation cannot curate the research data. The aim of the study is to identify the Asian Library and Information Science (LIS) faculties’ experiences in the research data preservation and curation during their research. Data management, curation and preservation all are interlinked. For reuse of the research data; data curation is an essential role. For this research, we adopted a survey method and an online questionnaire was shared with 1400 LIS professionals, belonging to the Asian region but the completed study respondents are 125 university faculties from various Asian countries. The study findings are 76.8 per cent generated statistical data followed by 58.4 per cent textual files. By far, the most preferable data analysis tool is Microsoft Excel 82.4 per cent. Moreover, the result shows that generated data is mostly stored by personal computers and laptop hard disks. This study concludes LIS faculties having adequate skills and knowledge on data curation and preservation even though they are expecting more services from their academic institute libraries.
The periodontal regeneration is one of the main objective in periodontal management and can be achieved by use of barrier membrane, bone grafts and growth factors. Calcium sulphate, an alloplast material and platelet rich fibrin was used in this clinical trial. Aims: To compare medical grade calcium sulphate hemihydrate with and without platelet rich fibrin as a bone regenerative material in the treatment of intraosseous periodontal defects by clinical and CBCT assessment. Materials and Methods: 30 defect sites were included in the study and were randomly allocated to either Group A, Group B or Group C. Group A was the control group, Group B included the placement of medical grade calcium sulphate hemihydrate whereas Group C included the placement of medical grade calcium sulphate hemihydrate with platelet rich fibrin in periodontal intrabony defects. Statistical analysis of plaque index, gingival index, probing pocket depth, clinical attachment loss and defect fill by CBCT was performed. Statistical analysis used: Kruskal Walis test and Chi‑square test for categorical variables were used for analysis. The critical levels of significance of the results were considered at 0.05 levels, i.e., P < 0.05 was considered statistically significant. Results: Statistically more significant difference in probing pocket depth, clinical attachment loss and defect fill was observed in Group C (MGCSH+PRF) in comparison to Group B (Medical Grade Calcium Sulphate Hemihydrate) which showed better results than Group A. Conclusion: MGCSH with PRF produced more favourable results than MGCSH alone.
HTTP is a stateless protocol thus we tend to use cookie to maintain session. For maintaining a session server creates a unique identifier to remember on going session for particular client. This distinctive identifier is nothing but a randomly generated text which is stored on client browser in the form of cookie. These cookies are generally created in the login process, after successful authentication process, server generates unique id for requested client and send it to client. Browser sends this cookie on every request where authentication of user is required. Authentication of cookie become temporary replacement of user password authentication for the entire session. Cookies are static in nature, they do not change in the session life time, because of this nature anyone can steal and use this cookie for their benefit. Use of cookies introduces a number of risks in security especially in session authentication. For secure communication use of HTTPS is not easy for those applications that are highly distributed due to performance and financial issues and HTTPS provide security at network only there are many ways were attacker can steal cookie by using different attack like cross site scripting attack, cross site tracing attack, domain related attack etc. Hence, creating a system using Concept of one-time dynamic cookie (OTDC) for authentication instead of HTTPS. OTDC will prevent various attacks on servers. A reverse proxy server with OTDC, IP Address, session ID and browser fingerprinting are used to prevent opponent from capturing session credentials. Setting up HTTPS to HTTP Reverse Proxy Server, Session time out implementation on Proxy server because "The less time you give your account to be cracked, the better for you." Generating log on attack detection and reporting to administrator.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
