Some Correlates of Risky User Behavior and ICT Security Awareness of Secondary School Students
Authors: Borić Letica Ivana
Published: April 2020

The aim of the research was to examine some correlates of security awareness and risky behavior while using information technology. The sample consisted of 206 participants; i.e., 150 female and 56 male students from three secondary schools. The Users’ Information Security Awareness Questionnaire, the Consciousness Subscale and the Self-Control Questionnaire were used. Results showed that there are statistically significant (low to moderate) correlations between some personality traits (self-control and consciousness) and time spent on the Internet, borrowing access data, different risky behaviors, computer maintenance and proper data storage. Adolescents show low levels of security awareness. Parents talk more about privacy and security risks with girls than with boys. Girls show more security awareness than boys but behave equally risky. Those with whom parents talk more about security risks show less risky behavior and more security awareness.

Efficient Physiological and Nutrient Use Efficiency Responses of Maize Leaves to Drought Stress under Different Field Nitrogen Conditions
Authors: Wang Yang , Huang Yufang , Fu Wen , Guo Wenqing , Ren Ning , Zhao Yanan , Ye Youliang
Published: April 2020

Inadequate water and nitrogen (N) supplies can limit the productivity of maize. Climate change will likely increase drought in many regions on a global scale. The determination of N fertilizer rates under field drought conditions will be critical toward the reduction of agricultural risk. For this study, drought-resistant/sensitive cultivars were selected as experimental samples. Our results revealed that drought stress reduced the relative water content (RWC) of leaves, which resulted in leaf curling, while decreasing photosynthesis levels and N accumulation. In contrast to those without N treatments, the application of N significantly increased grain yields by 26.8% during the wet year but increased only by 5.4% during the dry year. Under the same N levels, the reduction in yield caused by drought increased with the increased application of N. This was because the application of the N fertilizer translated to increase the leaf area and transpiration, exacerbated the soil water loss and induced a leaf curling state in maize, which had deleterious effects on photosynthesis and N absorption. During the dry year, the yields of drought-sensitive cultivars were even less than those without the application of N. Compared with those of drought-sensitive cultivars, the RWCs of drought-resistant cultivars decreased more rapidly, and they entered the state of leaf curling earlier. Thus, N fertilizer inputs should be reduced, and the extent of N fertilization for drought-sensitive cultivars should be reduced even further.
The Road Not Taken with Pyrrole-Imidazole Polyamides: Off-Target Effects and Genomic Binding
Authors: Lin Jason , Nagase Hiroki
Published: April 2020

The high sequence specificity of minor groove-binding N-methylpyrrole-N-methylimidazole polyamides have made significant advances in cancer and disease biology, yet there have been few comprehensive reports on their off-target effects, most likely as a consequence of the lack of available tools in evaluating genomic binding, an essential aspect that has gone seriously underexplored. Compared to other N-heterocycles, the off-target effects of these polyamides and their specificity for the DNA minor groove and primary base pair recognition require the development of new analytical methods, which are missing in the field today. This review aims to highlight the current progress in deciphering the off-target effects of these N-heterocyclic molecules and suggests new ways that next-generating sequencing can be used in addressing off-target effects.

Published: April 2020

An adverse reaction of dry skin occurs frequently during treatment with anticancer epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). In this study, we conducted basic research to clarify the mechanism of EGFR-TKI-induced dry skin and propose new treatments or preventative measures. Dermal water content was significantly lower in the erlotinib-treated mice than in the control group. An assessment of the expression levels of functional genes in the skin revealed that only the expression of the water channel aquaporin-3 (AQP3) was significantly decreased in the erlotinib-treated group. When erlotinib was added to epidermal keratinocyte HaCaT cells, the expression levels of both AQP3 mRNA and protein decreased. Erlotinib treatment also significantly decreased the expression levels of phospho-EGFR and phospho-extracellular signal-regulated kinase (ERK), both in HaCaT cells and mouse skin. Dry skin due to erlotinib may be caused by the decreased expression of AQP3 in the skin, thereby limiting water transport from the vascular side to the corneum side. The decrease in AQP3 may also be attributable to ERK suppression via inhibition of EGFR activity by erlotinib. Therefore, substances that increase AQP3 expression may be effective for erlotinib-induced dry skin.

Published: April 2020

Despite being referred to as the guardian of the genome, when impacted by mutations, p53 can lose its protective functions and become a renegade. The malignant transformation of p53 occurs on multiple levels, such as altered DNA binding properties, acquisition of novel cellular partners, or associating into different oligomeric states. The consequences of these transformations can be catastrophic. Ongoing studies have implicated different oligomeric p53 species as having a central role in cancer biology; however, the correlation between p53 oligomerization status and oncogenic activities in cancer progression remains an open conundrum. In this review, we summarize the roles of different p53 oligomeric states in cancer and discuss potential research directions for overcoming aberrant p53 function associated with them. We address how misfolding and prion-like amyloid aggregation of p53 seem to play a crucial role in cancer development. The misfolded and aggregated states of mutant p53 are prospective targets for the development of novel therapeutic strategies against tumoral diseases.
Spirochete Flagella and Motility
Authors: Nakamura Shuichi
Published: April 2020

Spirochetes can be distinguished from other flagellated bacteria by their long, thin, spiral (or wavy) cell bodies and endoflagella that reside within the periplasmic space, designated as periplasmic flagella (PFs). Some members of the spirochetes are pathogenic, including the causative agents of syphilis, Lyme disease, swine dysentery, and leptospirosis. Furthermore, their unique morphologies have attracted attention of structural biologists; however, the underlying physics of viscoelasticity-dependent spirochetal motility is a longstanding mystery. Elucidating the molecular basis of spirochetal invasion and interaction with hosts, resulting in the appearance of symptoms or the generation of asymptomatic reservoirs, will lead to a deeper understanding of host–pathogen relationships and the development of antimicrobials. Moreover, the mechanism of propulsion in fluids or on surfaces by the rotation of PFs within the narrow periplasmic space could be a designing base for an autonomously driving micro-robot with high efficiency. This review describes diverse morphology and motility observed among the spirochetes and further summarizes the current knowledge on their mechanisms and relations to pathogenicity, mainly from the standpoint of experimental biophysics.

Bariatric surgery improves glycemic control better than medical therapy; however, the effect of bariatric surgery on HDL function is not well characterized. Serum samples were available at baseline, 1-, and 5-years post procedures, for 90 patients with obesity and type 2 diabetes who were randomized to intensive medical therapy (n = 20), Roux-en-Y gastric bypass (RYGB, n = 37), or sleeve gastrectomy (SG, n = 33) as part of the STAMPEDE clinical trial. We examined serum HDL function by two independent assays, apolipoprotein A-1 exchange rate (AER) and cholesterol efflux capacity (CEC). Compared with baseline, AER was significantly higher at 5 years for participants in all treatment groups, but only increased significantly at 1 year in the RYGB and SG groups. CEC was divided into ABCA1-dependent and independent fractions, and the later was correlated with AER. ABCA1-independent CEC increased significantly only at 5 years in both surgical groups, but did not significantly change in the medical therapy group. There was no significant change in ABCA1-dependent CEC in any group. The increase in AER, but not ABCA1-independent CEC, was correlated with the reduction in body mass index and glycated hemoglobin levels among all subjects at 5 years, indicating that AER as a measure of HDL function would be a better reflection of therapy versus CEC.

Published: April 2020

Triple-negative breast cancer (TNBC) is a highly heterogeneous disease, representing the most aggressive breast cancer (BC) subtype with limited treatment options due to a lack of estrogen receptor alpha (ERα), progesterone receptor (PR), and Erb-B2 receptor tyrosine kinase 2 (HER2/neu) expression. Estrogen receptor beta (ERβ) is present in a fraction of TNBC patients, where its expression correlates with improved patient outcomes, supported by the fact that it exerts oncosuppressive effects in TNBC cell models in vitro. ERβ is involved in microRNA-mediated regulation of gene expression in hormone-responsive BC cells and could mediate its actions through small noncoding RNAs (sncRNAs) in TNBCs also. To verify this possibility, smallRNA sequencing was performed on three ERβ-expressing cell lines from different TNBC molecular subtypes. Several sncRNAs resulted modulated by ERβ, with a subset being regulated in a tumor subtype-independent manner. Interestingly, sncRNA profiling of 12 ERβ+and 32 ERβ− primary TNBC biopsies identified 7 microRNAs, 1 PIWI-interacting RNA (piRNA), and 1 transfer RNA (tRNA) differentially expressed in ERβ+ compared to ERβ− tumors and cell lines. Among them, miR-181a-5p was found to be overexpressed in ERβ+ tumors and predicted target key components of the cholesterol biosynthesis pathway previously found to be inhibited by ERβ in TNBC cells.
Large Animal Models of Inherited Retinal Degenerations: A Review
Authors: Winkler Paige A. , Occelli Laurence M. , Petersen-Jones Simon M.
Published: April 2020

Studies utilizing large animal models of inherited retinal degeneration (IRD) have proven important in not only the development of translational therapeutic approaches, but also in improving our understanding of disease mechanisms. The dog is the predominant species utilized because spontaneous IRD is common in the canine pet population. Cats are also a source of spontaneous IRDs. Other large animal models with spontaneous IRDs include sheep, horses and non-human primates (NHP). The pig has also proven valuable due to the ease in which transgenic animals can be generated and work is ongoing to produce engineered models of other large animal species including NHP. These large animal models offer important advantages over the widely used laboratory rodent models. The globe size and dimensions more closely parallel those of humans and, most importantly, they have a retinal region of high cone density and denser photoreceptor packing for high acuity vision. Laboratory rodents lack such a retinal region and, as macular disease is a critical cause for vision loss in humans, having a comparable retinal region in model species is particularly important. This review will discuss several large animal models which have been used to study disease mechanisms relevant for the equivalent human IRD.
Incorporation of Sustainability Concepts into the Engineering Core Program by Adopting a Micro Curriculum Approach: A Case Study in Saudi Arabia
Authors: Ashraf Muhammad Waqar , Alanezi Faisal
Published: April 2020

Higher education institutions are increasingly pursuing sustainable development goals in engineering and technology education. The concepts related to operations, production, and consumption continue to gain importance and significance for engineering students. In the engineering profession, the incorporation of sustainability means integrating environmental, economic, and social factors into the evaluation of design processes, products, and services. Therefore, it is necessary to develop an engineering program that along with the technical content, also fosters a critical sense regarding the social and environmental aspects of the field. The current status of sustainability education in engineering programs offered in Saudi universities is not very promising. In this paper, we explore the use of existing university curricula to incorporate sustainability elements into engineering education and training. Sustainability concepts were introduced into selected courses by using a micro-curriculum approach. Moreover, a standalone course is also introduced. We observed that this approach has been successful in integrating sustainability into the engineering curriculum. We recommend that such an approach be used to develop sustainability awareness in engineering programs.

How Bauhaus movement informs not only modern architecture but also modern theatre, dance, art, music, the structure of the stage, the idea of the space, etc.? The ‘theatre of Bauhaus’ is not a clear system of ideas shared by all the participants in the movement. On the contrary, there are many internal conflicts. But we could speak of concepts that were developed and became influential through Bauhaus, especially after the ‘branding’ of the movement in the US in the second half of 20th century.

This study embarked on an in‑depth content analysis of the
information literacy environment in the South African education
sector. The review of literature encompasses a comprehensive
critical analysis of available appropriate and contemporary
literature, which further expounds the research problem. This
research adopted the qualitative method of data collection; hence,
policy documents, conference proceedings and journal articles about
the subject matter were analytically evaluated to identify whether
there is a research gap that may have remained unanswered in
previous studies. The study emphasises various ICT tools and
techniques that will promote e‑learning in South African educational
sector; this was done in recognition of its essential role. South
Africa struggles with challenges associated with the digital divide,
a result of the inability of many to access ICT tools capable of
enhancing their performance, particularly in a racially divided
country such as South Africa, where a separate educational
development policy was pursued during the apartheid era, in favour
of the white minority. The trends in information literacy and
essential issues regarding information literacy skills in South
Africa are highlighted. The challenges associated with information
literacy in South Africa are presented, and different opportunities
in information literacy are also discussed. The paper concludes with
the gaps and options in information literacy in South Africa.
Finally, this paper offers a comprehensive review of the information
literacy development in the South African education sector, which
constitutes an essential perspective in the understanding of the

Poverty in Indonesia is still one of the social problems. Central Bureau of Statistics (BPS) noted, as of March 2017 the number of poor people, namely residents with per capita expenditure per month below the poverty line) in lndonesia reached 27.77 million people (10.64 percent of the total population). As quoted by the Head of BPS, that number increased 6.90 thousand people compared to September 2016 which amounted to 27.76 million people (10.70 percent). Although the percentage of poverty rates has decreased, in total the number has increased. Women's empowerment is an effective way to eliminate poverty, hunger, and disease and to support sustainable development. Some things must be considered in order shaping the model of empowering poor women is: the empowerment stage is preceded with the formation of empowerment models that are arranged systematically and scientifically, with combining theoretical aspects of empowerment, needs in the field, consultation with relevant agencies, literature review, as well as input from empowerment and gender experts, the existence of cooperatives was formed after the production system ran smoothly. Establishment of this cooperative need to be supported by motivating the consultant. High potential in undergoing an entrepreneurial profession or possessing high potential as a prospective entrepreneur or entrepreneur. Entrepreneurship training for Poor women in using the Project Based Learning model are considered effective because most participants are successful in terms of the level of mastery of personality (soul) entrepreneurship and skills possessed while gaining learning experience real business.
The site of Shaym Qalʿa, Marw oasis: reconsidering the chain of information
Authors: Francavilla Costanza
Published: April 2020

The ancient city of Marw, Turkmenistan, represents a unique case study for having been the object of many archaeological expeditions, from the pioneering mission of R. Pumpelly (1903-1904) to the most recent aerial-topographic studies of T. Williams “The Ancient Merv Project” (2001-2003). Nevertheless, the settlement dynamics during the transition from Late Sasanian to Early Islamic period (7th-8th cs. A.D.) are not well understood. This contribution focuses on some observations on the site of Shaym Qal.a, a quadrangular area close to the modern tepe of Gyaur Qal.a. The latter one represents the hellenistic Antiochia Margiana later determined to be an important shahrestan of the Sasanian’s northeastern territories. At first, it was hypothesized that Shaym Qal.a was a Seljuks military camp (11th-12th cs.), however recent archaeological studies have uncovered elements which could backdate the site to the 8th century. These data go along with Yakubovskii and Bosworth (1991) statements about the ancient Marw; so, the actual hypothesis is that Shaym Qal.a is an Early Islamic military camp, that is a mi.r. This paper illustrates this latter hypothesis including the favorable points challenges. In addition, this paper verifies two ancient authors, al-.abari and al-Muqaddasi. Through the readings of the Islamic historians the identification of Shaym Qal.a can be reconsidered.

Introduction: Histiocytosis is a heterogeneous group of rare diseases of unknown etiology. LCH is characterized by an abnormal proliferation of histiocytes (activated dendric cells and macrophages). Langerhans cell histiocytosis (LCH) is the most common form of histiocytosis, it is a potentially fatal diseases. Early detection of LCH plays an important role in its prognosis and outcome. However, the role of advanced methods of nuclear medicine in diagnosis of LCH is still to be researched. We have long-term experience in observing pediatric patients with LCH. Taking into the account the difficulty of diagnostic task for bone scintigraphy in identifying lytic bone destruction, we stated the following objective of the study.

Purpose: Retrospective and prospective analysis of bone scintigraphy examinations of treatment-naive pediatric patients with LCH and calculate the diagnostic efficacy of bone scintigraphy. Material and methods: We analyzed 60 examinations of treatment-naive pediatric patients with proven case of LCH (2014-2019). The scanning was performed using whole body mode, 3 hours after intravenous injection of bone-seeking radiopharmaceutical 99mTc-MDP on Symbia E, T2 (Siemens, Germany). The median age was 5.6 years.

Results: During examination we visualized 88 lesions with pathological level of accumulation of radiopharmaceutical in 60 patients. 84 with high level of accumulation (>120 %); 3 with slightly increased level of accumulation (100–120 %) and 1 with lower than normal level of accumulation (<100 %). The median level of accumulation of radiopharmaceutical was 268 %. Max level of accumulation was 1422 % (patient with subtotal involvement of femoral bone). Min — 60 % (patient with lytic destruction in orbital bone). During X-Ray we found out 97 pathological focuses of bone lytic destruction. In 3 patients with polyostotic form we found extra focuses on scintigraphy, which were confirmed with following examination and X-Ray. 8 lesions were not found on scintigraphy in 8 patients.

Сonclusions: We evaluated diagnostic accuracy of bone scintigraphy with 99mTc-MDP in treatment-naïve pediatric patients with proven case of LCH. Sensitivity, specificity, NPV and PPV — 91.6, 50.0, 11.1, 98.6 %, respectively.

One primary drawback of enzyme catalysis at industrial scale is the short term service life of the enzymes. Enzymes lose their activity due to oxidation or other processes which results in less stability and a shorter lifetime thereby rendering them less efficient. An effective way to increase the stability, longevity and reusability of the enzymes is to attach them to nanoparticles by applying the double-emulsion technique. In this work the polymer Eudragit® L 100-55 sensitive to pH was used to prepare laccase polymeric nanoparticles by the double-emulsion solvent evaporation approach. The size and morphology of the nanoparticles obtained was evaluated by Scanning Electron Microscope and particle size distribution was assessed by Photon Correlation Spectroscopy. Encapsulation efficiency and zeta potential were calculated. The effect of pH on laccase activity and stability was compared between free laccase and the immobilized one. Their stability was also determined in a sequential assay involving acidic pHs up to alkaline ones. The nanoparticles had a spherical shape with a mean size of 289 nm, zeta potential of -22.7 mV at pH 7.0, and load efficiency of 87%. The optimum pH of both free and immobilized laccases was 3.0, being the nanoparticles more stable at acidic pHs (2.0-4.0). Howevwe, this last kept 80% of enzyme activity at pH 2.0 approx., after 24 h. The polymer Eudragit® L 100-55 also conferred them resistance towards the pHs usually found at the gastrointestinal tract. These results suggest the potential use of nanoparticles as adjuvants in animal feed, serving as carriers for oral laccase delivery.
Civil responsibility in air transport: a perspective after the uptodate Rome 1952 international treaty
Authors: Da Rocha Artur Antonio , De Araujo Junior Antonio Henriques
Published: April 2020

This paper analyzes the civil responsibility of air transport carriers in accordance with the “Unification Convention Rules for International Air Transportation”. The matter of civil responsibility is a complicated and conflicting theme for analysis due to the difficulty even greater to the additional problem of having to define responsibilities when a disaster of great proportions takes place. Contrary to other modes of transportation, in the case of air transport there is rarely partial damage (when an accident occurs), therefore it is important to remember that in an aeronautical accident, the damages (or sinister) are not partial, they are total. On the other hand, should be considered that the airline industry is global, in which parts of a whole can come from distant countries involving partners from different countries with different realities and legal liability. The existence of joint responsibility of partners involved in the airline industry is what is meant to identify with this article.
ENHANCING AIRLINE PASSENGERS’ SATISFACTION THROUGH SERVICE QUALITY: THE IMPORTANCE OF THE “HUMAN FACTOR”
Authors: Salamoura Maria , Chaniotakis Ioannis , Lymperopoulos Constantine
Published: April 2020

The aim of this paper is to investigate the effect of service quality dimensions to overall satisfaction in the Greek airline industry. Data were collected through field research among 300 respondents, who have used a specific airline industry recently. Data analysis using structural equation modelling suggests that the performance of in-flight attendants and ground-service personnel are important factors in determining perceptions of service quality and overall satisfaction, together with reliability and satisfactory pricing arrangements. These “human factors” are shown to play a role both directly and indirectly in determining customer satisfaction in the airline context.

A density matrix approach to the convergence of the self-consistent field iteration
Authors: Upadhyaya Parikshit , Jarlebring Elias , Rubensson Emanuel H.
Published: April 2020

In this paper, we present a local convergence analysis of the self-consistent field (SCF) iteration using the density matrix as the state of a fixed-point iteration. Conditions for local convergence are formulated in terms of the spectral radius of the Jacobian of a fixed-point map. The relationship between convergence and certain properties of the problem is explored by deriving upper bounds expressed in terms of higher gaps. This gives more information regarding how the gaps between eigenvalues of the problem affect the convergence, and hence these bounds are more insightful on the convergence behaviour than standard convergence results. We also provide a detailed analysis to describe the difference between the bounds and the exact convergence factor for an illustrative example. Finally we present numerical examples and compare the exact value of the convergence factor with the observed behaviour of SCF, along with our new bounds and the characterization using the higher gaps. We provide heuristic convergence factor estimates in situations where the bounds fail to well capture the convergence.
