SALMAKA: Secured, Anonymity Preserving and Lightweight Mutual Authentication and Key Agreement Scheme for WBAN
Authors: Narwal Bhawna , Mohapatra Amar Kumar 
Published: May 2020

Background:
It is paramount to secure the healthcare system from unauthorized users
and security attacks through appropriate security mechanisms as a break in the communication
process and which leads to leaked or blurred messages, which is totally unacceptable. Moreover,
mutual authentication is a core requirement for privacy protection as it is paramount to control
who is accessing the sensed data and whether they are authenticated or not. In addition to this, energy
efficiency is a major issue to be discussed.

Objective:
After examination of the present related schemes, we proposed a novel Secured,
Anonymity Preserving and Lightweight Mutual Authentication and Key Agreement Scheme
(SALMAKA) for two-hop WBAN topology; where the scheme mutually authenticates the
sensing nodes with the controller node in an anonymous, energy efficient manner and establishes
session key securely.

Method:
To corroborate the accuracy of the proposed scheme, Burrows-Abadi-Needham (BAN)
logic and Automated Validation of Internet Security Protocols and Applications (AVISPA)
simulator are used. Apart from this, informal security evaluation is also performed in detail.

Results:
To exhibit the practical application and performance of the proposed scheme, it is
compared with the existing related schemes and the results reveal that the proposed scheme
reduces energy consumption, processing cost and processing time significantly.

Conclusion:
A Secured, Anonymity Preserving and Lightweight Mutual Authentication and Key
Agreement Scheme (SALMAKA) for two-hop WBAN topology is propounded.

Objective: To develop a new cationic nanoemulsion (NE) for ophthalmic delivery of indomethacin (IND) to improve the permeability and retention time of formulations, thereby improving the drug's ocular bioavailability.
Methods: Based on the solubility profile of indomethacin in various solvents, captex 8000 was selected as oil phase, span 20 as a surfactant and tween 20 as co-surfactant to construct pseudo ternary phase diagrams and nanoemulsion region was recognized. Sonication was used as the method of NE preparation. Optimization was done using 32 factorial designs by considering the oil and the ratio of surfactant to co-surfactant (Smix) quantities as independent variables and evaluated for different physicochemical properties. Ex vivo transcorneal permeability was studied using bovine cornea, the In vivo drug pharmacokinetics of optimized NE and marketed formulation were assessed in rabbit aqueous humor and also in plasma.
Results: The mean globule size, zeta potential, viscosity, refractive index, pH, surface tension and the osmolarity values for the prepared indomethacin nanoemulsions (IND-NEs) were found between 129.8±1.1 to 191.4±1.6 nm,+13.20±4.6 to+23.45±4.82, 15.3±0.1 to 32.7±0.0 mPas, 1.346±0.007 to 1.386±0.005, 5.5±0.4 to 6.9±0.9, 32.0±2.6 to 52.3±3.4 mN/m and 303-395 mOsm/l respectively and all these values found to be falling under the recommended values for ophthalmic use. From the In vitro release studies, it was found that the IND-NEs exhibited sustained drug release with 67.91±2.01 to 95.90±1.93 % drug release at 24h when compared to the drug solution which showed 99.81±5.21 % drug release within 2h. The Ex vivo drug permeation through the corneal membrane at 4h from the optimized NE and drug solution was found to be 524±1.5 µg/cm2 and 175±2.6 µg/cm2 respectively. Further, the optimized NE was found to be nonirritant with the lowest ocular irritation potential (Iirr) of 1 towards the rabbit's eyes. The area under the drug concentration vs. time curve for 24h (AUC (0–24h)) for optimized NE and the marketed formulation was found to be 1514.99 ng/ml/h and 974.14 ng/ml/h in aqueous humour; 2266.83 ng/ml/h and 778.15 ng/ml/h in plasma respectively.
Conclusion: Due to its improved corneal absorption and prolonged drug release along with less systemic absorption, the optimized NE offers an effective postoperative treatment with increased ocular bioavailability and improved patient compliance with a decrease in the number of installations per day and a decrease or disappearance of systemic side effects of IND.

Published: May 2020

The interest to do this research is to investigate the impact of technology transformation on the lecturer's performance. The terms technical performance in this research are divided into five (5) indicators: engaging and empowering learning, and teaching with technology, leadership, accommodation (syllabus and lesson scheme), and infrastructure provided by the campus. The findings indicate that many lecturers have a lack of knowledge in technology transformation. However, all lecturers must have it for the teaching and learning process in the 21st-century. The research methods used were descriptive analysis, observations, quantitative and semi-structured qualitative research, and the questionnaires done using Google Form. There were sixty-four (64) respondents in this research. The result shows that the use of technology proves its significant impact on the lecturer's performance.

Summary

Most recirculation aquaculture systems (RAS) use aerated biofilters to maintain suitable water quality for fish production. However, application of non-aerated biofilters may provide opportunities to lower aeration costs, water usage and concentration of all nitrogenous wastes in the effluent water. Our study aimed at comparing the biofiltration performance characteristics of two biofilters: a conventional aerated biofilter and a non-aerated biofilter receiving the same effluent water from a small-scale RAS. The two biofilters were evaluated in triplicate and tested concurrently for seven months. Water quality parameters were monitored at the biofilter inlets and outlets and in the fish tanks. At the beginning of the experiment, the concentration of ammonia at the two biofilter outlets were not significantly different. However, the concentrations decreased with time reaching mean values of 1.33 ± 0.02 mg L−1 and 1.23 ± 0.21 mg L−1 N-NH4 in the aerated and non-aerated biofilters, respectively. Whereas phosphorus and nitrate levels were significantly high in the aerated biofilter. There was no significant difference in the growth of fish between the aerated and non-aerated biofilters. The results suggest that non-aerated biofilters can be as effective as aerated biofilters in maintaining suitable water quality for O. niloticus production.

Abstract
Improving collaboration in Dutch maternity care is seen as essential to improve continuity of care and thereby safety, client satisfaction, and health outcomes. This study aims to monitor and evaluate whether the regional Maternity Care Network Northwest Netherlands (MCNNN) and its local multidisciplinary obstetric partnerships contributed to collaboration. This mixed-method study followed the methodology of reflexive monitoring in action. Data were collected from 2014 to 2016 through interviews (n=73), questionnaires (n=430), and reflection sessions (n=4) and analyzed inductively and deductively based on a model for interprofessional and interorganizational collaboration. The findings outline (1) MCNNN-activities, (2) experienced collaboration within obstetric partnerships, and (3) MCNNN as supporting structure. The findings showed improvements on both the relational and organizational level of interprofessional and interorganizational collaboration. The MCNNN’s meetings, products, and research projects facilitated knowledge development and dissemination and its obstetric partnerships fostered contact and deliberation among maternity care professionals. However, collaborative challenges were also experienced, including mistrust and difficulties in information sharing, influenced by lacking financial and organizational facilitation. The MCNNN could improve its supporting role in the system innovation toward integration in maternity care by means of a further transformation to a knowledge network that is focused on reflexively overcoming collaborative challenges at all levels in the maternity care system.
On-site inspections: the shift from forms to digital capture
Authors: Rolfsen Christian Nordahl , Lassen Ann Karina 
Published: May 2020

AbstractThe building, construction, and real estate industry is undergoing a major transition with traditional ways of working being replaced by novel three-dimensional modeling technologies. Such transitions take place incrementally as more and more actors see the advantages. While new systems (e.g., building information modeling) have become increasingly diffused in the industry, many practices have been left intact. On-site inspections using the old method of filling out forms for the registration of errors and omissions are eventually replaced by defect management systems, where an app on a mobile device is used to take a photo, note position, and write notes, which are directly sent to the responsible people involved. A case study was conducted in a large residential project under completion by a contractor. Project managers and skilled workers were introduced to a specific app and given the opportunity to try it out. Data were subsequently collected based on a series of qualitative interviews conducted with the on-site personnel. This was analyzed according to the technology acceptance model, a theory of user acceptance of new information technologies. Our contribution is that we compare the technology acceptance of new and existing defect management methods and unearth their relative advantages, while registering how users’ perceptions of new technology affect their intention to use as well as their actual continued use of the technology. This work is important for managers planning development of their on-site management tools, enabling them to run their projects more efficiently.
Detecting unbalanced bids via an improved grading-based model
Authors: Polat Gul , Turkoglu Harun , Damci Atilla , Akin Firat Dogu 
Published: May 2020

Abstract
Unbalanced bidding, also known as skewed bidding, is the process of increasing and/or decreasing the prices of various bid items without altering the total offered bid price. Bids can be unbalanced either mathematically (front-end loading) or materially (quantity error exploitation). Owners should be very careful when evaluating the tenders as awarding a contract to an unbalanced bid may result in severe cost overruns because the prices of those items do not reflect their true costs and markup allocations. Unbalanced bidding is still a contentious issue in the construction industry. While some researchers consider it as a legal bidding strategy in such a fierce competitive business environment, others view it as an unethical practice and claim that unbalanced bids should be disqualified. Studies regarding unbalanced bidding can be categorized into two groups: (1) the ones focusing on detecting or preventing this practice to help owners; and 2) the ones focusing on optimizing unbalanced bidding to help contractors. This study aims to develop a model, which consists of eight grading systems, to assist owners in detecting materially unbalanced bids. The proposed model is the improved version of the previous model, which was composed of five grading systems. In order to demonstrate how this grading-based model can be used by owners, an illustrative example is presented. It was found that owners can easily and successfully detect unbalanced bids via the proposed model.
Industrialization of construction: Implications on standards, business models and project orientation
Authors: Andersson Niclas , Lessing Jerker 
Published: May 2020

Abstract
Digitalization has the potential to radically change the way buildings are designed, produced, and operated. In this digital transformation, the establishment of information standards play an important role. However, despite substantial efforts in the development of both technology and standards, these are not yet fully adopted in construction. This study aims to review the adoption of standards and to examine whether suppliers of prefabricated concrete elements have transformed their business models. The purpose is to strengthen the understanding of the interplay between the adoption of standards and business model renewal. Driving forces for the adoption of standards are identified and coupled with suppliers’ arguments for business model protection and renewal, explained in terms of a market and a hierarchy approach. The market approach embraces the adoption of open standards for improved competition and information exchange along with the further adoption of industrialized construction. This study identifies that common standards for precast elements are lacking, which leads to waste in terms of structural re-design and liability uncertainties. On the other hand, a market situation with open standards is challenging for suppliers to utilize and benefit from their existing operational platforms. Suppliers of precast elements strive for a hierarchy approach, that is, the adoption of the whole value chain, to protect their market position and continue offering structural frameworks and services. This concurs with arguments for industrialized construction, which emphasize the benefits of continuous improvements. This study contributes to the understanding of drivers and impediments for the uptake of standards versus business model renewal in construction.

Published: May 2020

Abstract
The coordinates of 18°26′ and 19°22′ east latitude and 41°52′ and 43°32′ north longitude set geographic position of Montenegro. The total length of its land borders is 614 km. The border alongside Croatia is 14 km long, alongside Bosnia and Herzegovina 225 km, alongside Serbia 20 km, and alongside Albania 172 km of the state border (partly across the Scadar lake and alongside the river Bojana). There is a 100 km of air distance between the furthest points at the sea. The factual length of the Montenegrin coast is about 280 km, which makes the serrated coefficient of 2.8. Montenegro is in proportion to its territory and population the smallest of all ex-Yugoslav republics. It spreads over the area of 13,812 square kilometres which makes 5.4% of ex-Yugoslav territory. According to 2003 census, 620.145 citizens lived in 1240 settlements, which were 45 citizens on a square kilometre. Out of 21 municipalities six are in the coastal region. The largest municipality in Montenegro (as well as in both ex-Yugoslavia and in the State union of Serbia and Montenegro) is Nikšić with 2,065 square kilometres, and the smallest is Tivat with 46 square kilometres. The capital of Montenegro is Podgorica with population of 96,076.
“Dúthaigh Na Súpanna”: An Insight Into “Souper Territory” from the Folkloric Repertoire of Seán Mac Criomhthain
Authors: Mac An tSionnaigh Seaghan 
Published: May 2020

Abstract
West Kerry storyteller Seán Mac Criomhthain (1873-1955) was born almost a quarter-century after the Great Irish Famine. Nevertheless, his upbringing occurred in a context which included both overt and covert references to the kinds of sectarian divisions which initially had contributed to the famine, and which later were entrenched by it. Sectarian division in the Irish context expressed itself primarily via denominational attachment, and to a lesser extent, along linguistic lines. Such divisions were explored across the country through traditional lore and through song; and in the specific repertoire of Seán Mac Criomhthain, through the medium of a mellifluous ‘brand’ of Munster Irish for which the Corca Dhuibhne peninsula has since become renowned. This article attempts to describe attitudes to sectarian division in the evidence of Mac Criomhthain’s repertoire. With extensive reference to a composition translated for the first time to English, it will be argued that concerns of immediate social pragmatism are afforded much greater importance than those of denominational or linguistic attachments.

Summary

Objectives
. To assess the association between education degree and attitude towards the treatment after myocardial infarction (MI).

Design and Methods
. The participants of this cross-sectional study were 191 (140 men and 51 women) outpatients in a period of 3 months – 5 years after acute MI (mean age 59 ± 9.2 years) from Vilnius University Hospital Santaros Klinikos. All patients were asked to complete two questionnaires: “Quality of Life and Treatment after Myocardial Infarction” and “Cholesterol-lowering Drugs Consumption Peculiarities”. The data was analyzed using the SPSS software.

Results
. The education degree (a higher (post-secondary education provided by a college or university) vs. a lower (secondary or vocational education) education degree) had similar influence on the patients’ occasional concern (43.2%; n = 35 vs. 52.9%; n = 55, respectively; p = 0.226) and on the frequent concern (25.9%; n =21 vs. 26.9%; n = 28, respectively; p = 0.226) about MI. Patients with a higher education degree were more likely to identify themselves as the main subjects in MI treatment in comparison with patients that had a lower education degree (30.5%; n = 25 vs. 15.2%; n = 16, respectively, p = 0.033). More educated patients found it easier to follow up the doctor’s treatment plan than less educated patients (23.2%; n = 19 vs. 9.5%; n = 10, respectively; p = 0.035).

Conclusions
. More educated patients are more likely to follow up the doctor’s treatment plan and see it easier than less educated patients. Thus, more attention should be paid to less educated patients in order to increase their own impact on their post-MI treatment.

Published: May 2020

Abstract
Research on the state and dynamics of the gene pool (an important natural resource that determines the potential fitness of living organisms and, ultimately, their long-term survival) becomes an important problem in the context of increased anthropogenic environmental impact. They are especially important for key species of ecosystems of a global scale importance. Larix sibirica Ledeb., which spreads from the Western Siberia to the Russian North-West, is one of such forest tree species. We identified patterns of genetic structure of populations on the example of the species’ Western race on the Middle and Northern Urals. The analysis of nucleotide polymorphism of genes of ABA-inducible protein, MADS-box-transcription factor and of 4-kumarat: CoA ligase (a part of the gene) was used as a method. Evidences were obtained that a part of the populations previously formed a single large population. At the same time, populations with different gene pools were found. As a result, differences between populations within the region were more pronounced (fixation index FST = -0.021 – 0.260, total haplotype diversity Hd = 0.636 – 0.911; nucleotide diversity π = 0.005 – 0.009; number of mutations θW = 0.005 – 0.012) than in other parts of the race. Causes of this phenomenon are discussed. It was concluded that the larch forests with a unique gene pool and/or high genetic diversity should be objects of population-oriented forestry and conservation.

Abstract
Genetic variability in date palm genotypes collected from different regions of southern Tunisia was analyzed using a Start Codon Targeted (SCoT) marker system. Thirty-one accessions collected from three locations were investigated. One hundred and nine amplicons were produced among which 84 % were polymorphic. The PIC value and the Rp values testified of the efficiency of used primers. The percentage of polymorphic loci (Pp) varied from 44.57 to 83.70 %, Nei‘s gene diversity (H) from 0.175 to 0.273 with a mean of 0.228, and Shannon‘s information index (I) values ranging from 0.257 to 0.409 with an average value of 0.338 were illustrated. The Tunisian date palm populations exhibited high genetic differentiation (GST = 0.319) and gene flow (Nm = 1.063). The AMOVA analysis presented 70 % of the variation within the population and 30 % of the variation between them. Phylogenetic analysis and the Bayesian clustering approach also revealed high genetic variation among genetic variants with a net divergence of the wild insular population of Kerkennah from other cultivars. The present investigation suggests the effectiveness of the SCoT marker system to estimate the genetic diversity of Phoenix dactylifera genotypes.
Using the potential of peripheral green areas of cities for educational and recreational purposes on the example of Stary Sącz, Nowy Targ and Kraków
Authors: Kulig Mateusz , Przeniczny Anna , Ogórek Piotr 
Published: May 2020

AbstractGreen areas located on the peripheries of cities have the potential to become green public spaces not only of recreational but also educational character, promoting at the same time the knowledge about environmental protection. The cities included in the research belong to the małopolskie voivodeship (Lesser Poland voivodeship). With the use of geospatial data of land cover, as well as territorial forms of environmental protection, it was pointed that 48.4% of forest, wooded and shrub green areas located within city borders are covered by a form of environmental protection, thus being a valuable resource of significant nature potential. Making such spaces available in a conscious and attractive way is presented on the example of projects implemented in the cities of: Stary Sącz, Nowy Targ and Kraków. The presented projects were used to make recommendations for city authorities to create green public spaces.
