A reliable next generation cyber security architecture for industrial internet of things environment

Architectural changes are happening in the modern industries due to the adaption and the deployment of ‘Internet of Things (IoT)’ for monitoring and controlling various devices remotely from the external world. The most predominant place where the IoT technology makes the most sense is the industrial automation processes in smart industries (Industry 4.0). In this paper, a reliable ‘Next Generation Cyber Security Architecture (NCSA)’ is presented for Industrial IoT (IIoT) environment that detects and thwarts cybersecurity threats and vulnerabilities. It helps to automate the processes of exchanging real-time critical information between devices without any human intervention. It proposes an analytical framework that can be used to protect entities and network traffics involved in the IIoT wireless communication. It incorporates an automated cyber-defense authentication mechanism that detects and prevents security attacks when a network session has been established. The defense mechanism accomplishes the required level of security protection in the network by generating an identity token which is cryptographically encrypted and verified by a virtual gateway system. The proposed NCSA improves security in the IIoT environment and reduces operational management cost

Lobster breeding, Sea ranching and juvenile fattening

Lobsters are one of the highly esteemed seafood delicacies and cu r re n t ly fetch the highest unit value among commercially exploited marine resources. These are decapod crustaceans belonging to fo u r fami l ie s : Nephropidae {clawed / true lobsters), Palinuridae {Spiny/ rock lobsters), Scyllaridae (Sand /slipper lobsters) and Synaxidae (Coral lobsters). Representatives of the families Palinuridae and Scyllaridae constitute the lobster fisher000y of India

Fecundity and viability of eggs in wild breeders of spiny lobsters, Panulirus homarus (Linnaeus, 1758), Panulirus versicolor (Latrielle, 1804) and Panulirus ornatus (Fabricius, 1798)

Berried lobsters collected from landing centres and lobster holding centres were used for larval rearing of the spiny lobsters, Panulirus homarus (Linnaeus, 1758), Panulirus ornatus (Fabricius, 1798) and Panulirus versicolor (Latrielle, 1804). Fecundity of the lobsters used for larval rearing was calculated as the number of eggs deposited on the ovigerous setae on the pleopods. The number of eggs in a single brood ranged from 1,20,544 to 4,49,585 in P. homarus. 5,18,181 to P.ornatus 1,979,522 and that of P. versicolor as 1,70,212 to P.versicolor 7,33,752. The tropical lobsters are reported to and therefore breed two times or more in a year. The absolute (annual) fecundity of these lobsters is expected to be higher. The phyllosoma larvae released, as percentage of fecundity, was maximum in P. homarus 85.7, 49.7 in P. ornatus and 74.0 in P. versicolor. Handling of lobsters at the landing and holding centres and aerial transport resulted in high percentage of eggs in arrested development, complete or partial shedding of eggs and release of weak phyllosoma larvae. Severe bacterial infection leading to complete shedding of eggs was recorded in a few breeders collected from holding centres

Leprosy among Patient Contacts: A Multilevel Study of Risk Factors

Leprosy is an infectious disease that can lead to physical disabilities, social stigma, and great hardship. Transmitted from person to person, it is still endemic in developing countries, like Brazil and India. Effective treatment has been available since 1960, but early diagnosis of the disease remains the most effective way to stop the transmission chain and avoid late diagnoses and subsequent disabilities. Knowledge of the risk factors for leprosy can facilitate early detection; therefore, our study aimed to investigate the factors presented by leprosy patients and their contacts, who are considered at highest risk of contracting the disease. We studied 6,158 contacts of 1,201 patients under surveillance from 1987 to 2007 in a Public Health Care Center in the City of Rio de Janeiro, Brazil. We evaluated the ways patient and contact demographics and epidemiological characteristics were associated with the detection of leprosy. Statistical analyses took into account both individual and group characteristics and their interrelationships. The main characteristics facilitating the contraction of leprosy among contacts were shown to be consanguinity and household association. Conversely, the bacillary load index of leprosy patients was the principle factor leading to disease among their contacts

Impact of PGL-I Seropositivity on the Protective Effect of BCG Vaccination among Leprosy Contacts: A Cohort Study

Although leprosy has become a neglected disease, it is an important cause of disability, and 250,000 new cases are still diagnosed worldwide every year. The current study was carried out in Brazil, where almost 40,000 new cases of leprosy are diagnosed every year. The study targeted contacts of leprosy patients, who are at the highest risk of contracting the disease. We studied 2,135 contacts who were diagnosed at the Leprosy Outpatient Clinic at the Oswaldo Cruz Foundation in Rio de Janeiro, RJ, Brazil, between 1987 and 2007. The presence of antibodies against a specific Mycobacterium leprae antigen (PGL-I) at the first examination and BCG vaccination status were evaluated. PGL-I-positive contacts had a higher risk of developing leprosy than PGL-I-negative contacts. Among the former, vaccinated contacts were at higher risk than unvaccinated contacts. Our results indicate that contact examination combined with PGL-I testing and BCG vaccination appears to justify the targeting of PGL-I-positive individuals for enhanced surveillance. Furthermore, it is highly recommended that PGL-I-positive contacts and contacts with a high familial bacterial index (i.e., the sum of results from index and co-prevalent cases), regardless of serological response, should be monitored. This group could be considered as a target for chemoprophylaxis

Patient Monitoring for Personalized Mobile Health (PMH) based on Medical Virtual Instruments

One of the newest technologies, mobile health, has the potential to support the provision of care for older adults and offer them individualised treatment. This study’s goal is to evaluate the benefits and challenges of personalised mobile health (PMH) for elderly residential care. Virtual worlds are quickly integrating into the landscape of instructional technologies. One of the most well-known of these settings is Second Life (SL). Despite the potential of SL for health professions education, there aren’t many official SL applications for this purpose, and the effectiveness of these applications hasn’t been evaluated to the fullest extent possible. Similarly, it appears that nothing is known about the use of virtual worlds for continuing medical education. In order to better grasp the fundamentals of the aid of MVIs for personal health monitoring (PHM), we were able to pinpoint the key disease regions, sensors, channels, calculations and communication protocols. The main obstacles limiting MVIs’ degree of integration into the international health care system were also identified. The analysis demonstrates that MVIs offer an excellent possibility for the creation of affordable, personalised health systems that meet the unique equipment requirements of a certain field of medicine
