Authors: Skulberg Knut Ragnvald , Hamid Samarullah , Vaktskjold Arild
Published: October 2019

Background: Use of tobacco may cause severe diseases like cardiovascular diseases and lung cancer. Smoking is a major threat to public health in many low- and middle-income countries.Objective: The aim of this study is to assess the prevalence of smoking among boys in the age group 13-15 years at Pulau Weh in Indonesia, and identify factors associated with smoking.Methods: A cross-sectional study was conducted of 291 male students, aged 13-15 years, in three participating secondary schools. A modified version of the Global Youth Tobacco Survey questionnaire was used to collect data. The association between active smoking within the previous 30 days, and social and demographic factors was analysed by multiple logistic regressions.Results: 40.2% of the male students were habitual smokers at the time of the study. The adjusted odds of current smoking increased with increasing age (odds ratio [OR] = 5.1, 95% CI: 2.2–12.3); having a father with a university or university college education (OR = 2.7, 95% CI: 1.0–7.1); having friends who smoke (OR = 5.2, 95% CI: 1.6–16.5), having sibling who smoke (OR = 2.7, 95% CI: 1.2–6.2); having a father who smokes (OR = 2.1, 95% CI: 1.1–3.9) and attending a rural school (OR = 7.4, 95% CI: 2.8–19.6).Conclusions: Cigarette smoking was found to be prevalent among 13 to 15-year-old male students in Pulau Weh, Indonesia, significantly higher in students attending a rural school compared to those attending an urban school. Indonesia should take steps to redress the smoking epidemic among adolescents by various means, e.g., minimizing access to tobacco products, stricter enforcement of tobacco control laws and changing attitudes to smoking.
Ultrafast processes triggered by one- and two-photon excitation of a photochromic and luminescent hydrazone

Published: October 2019

In this work we apply a combination of steady state and time resolved luminescence and absorption spectroscopies to investigate the excited-state dynamics of a recently developed molecular photoswitch, belonging to the hydrazone family. The outstanding properties of this molecule, involving fluorescence toggling, bistability, high isomerization quantum yield and non-negligible two-photon absorption cross section, make it very promising for numerous applications. Here we show that the light induced Z/E isomerization occurs on a fast <1 ps timescale in both toluene and acetonitrile, while the excited state lifetime of the Z-form depends on solvent polarity, suggesting a partial charge transfer nature of its low lying excited state. Time-resolved luminescence measurements evidence the presence of a main emission component in the 500–520 nm spectral range, attributed to the Z-isomer, and a very short living blue-shifted emission, attributed to the E-isomer. Finally, transient absorption measurements performed upon far-red excitation are employed as an alternative method to determine the two-photon absorption cross-section of the molecule.

From systemic perspective reconstruction and restoration of industrial buildings are similar to historical and cultural
heritage buildings. The maintenance and reuse of these buildings becoming more and more important research area worldwide. This
importance must increase the information management demand but however, the most advanced digital technologies are rarely used.
Use of 3D modelling technologies or whole building information modelling (BIM) methodology can help to save digital information
of historic buildings is a significant effort to preserve the heritage and retain its most valuable features.
Sustainable modernization method to increase energy performance of the public buildings using BIM techniques
Authors: Starynina Jovita , Ustinovičius Leonas , Vaišnoras Mantas
Published: October 2019

This research represents sustainable building modernization model, which creates knowledge-based decision-making
method for old public buildings refurbishment seeking to reach the best energy performance during the design stage. Despite the fast
development and spreading standards, challenging research opportunities arise from process automation and BIM adaptation for
existing buildings’ requirements. To aid decision-making, building simulation is widely used in the late design stages, but its
application is still limited in the early stages in which design decisions have a major impact on final building performance. Building
design is a multi-collaborator discipline, where architects influence design decisions, engineers, contractors, and building owners.
Using digital systems and simulations this modernization method performs already expected building energy consumption in a
quickest and economic way. This model is BIM-based where design and refurbishment are based on pre-built indicators, which
allows assessing the building energy demand and eco-building parameters.

Published: October 2019

Performance measurement encourages Decision Making Units (DMUs) to improve their level of performance by comparing their current financial positions with that of their peers. Data Envelopment Analysis (DEA) is a widely used approach to performance measurement, though it is susceptible when the data is heterogeneous. The main objective of this study is to examine the performance of Mongolian listed companies by combining DEA and a k-medoid clustering method. Clustering facilitates the characterization and patterns of data and identification of homogenous groups. This study applies the integration of k-medoids and performance measurement. The research used 89 Mongolian companies’ financial statements from 2012 to 2015 - obtained from the Mongolian Stock Exchange website. The companies are grouped by k-medoids clustering, and efficiency of each cluster is evaluated by DEA. According to the silhouette method, the companies are classified into two clusters which are considered first cluster as small and medium-sized (80), and second cluster as big (9) companies. Both clusters are analyzed and compared by financial ratios. The mean efficiency score of big companies’ is much higher than that of small and medium-sized companies. Integrated results show that cluster-specific efficiency provides better performance than pre-clustering efficiency results.
Detection of Phosphorus-bearing Molecules toward a Solar-type Protostar

Published: October 2019

Phosphorus is a key ingredient in terrestrial biochemistry, but is rarely observed in the molecular interstellar medium and therefore little is known about how it is inherited during the star and planet formation sequence. We present observations of the phosphorus-bearing molecules PO and PN toward the Class I low-mass protostar B1-a using the IRAM 30 m telescope, representing the second detection of phosphorus carriers in a solar-type star-forming region. The P/H abundance contained in PO and PN is ∼10−10−10−9 depending on the assumed source size, accounting for just 0.05%–0.5% of the solar phosphorus abundance and implying significant sequestration of phosphorus in refractory material. Based on a comparison of the PO and PN line profiles with the shock tracers SiO, SO2, and CH3OH, the phosphorus molecule emission seems to originate from shocked gas and is likely associated with a protostellar outflow. We find a PO/PN column density ratio of ∼1–3, which is consistent with the values measured in the shocked outflow of the low-mass protostar L1157, the massive star-forming regions W51 and W3(OH), and the galactic center GMC G+0.693-0.03. This narrow range of PO/PN ratios across sources with a range of environmental conditions is surprising, and likely encodes information on how phosphorus carriers are stored in grain mantles.

Published: October 2019

Introduction: Enterococci have emerged in last two decades as serious hospital acquired pathogens particularly vancomycin resistant strains (VRE). The study aimed to identify the prevalence of enterococcal isolation from hospital infections and colonization as well as determine vancomycin resistance phenotypes and genotypes. Methods: Sixty enterococcus isolates were isolated from patients, health care workers and hospital environment, identified and tested for antimicrobial susceptibility. Enterococcus species were identified by Real-time PCR and vancomycin resistance was assessed by agar dilution method and Real-time PCR.

Results; out of 300 samples (20%) were enterococci (53.3% were E. faecium, 31.7% E. faecalis and 10% other enterococci). Among of them 40/60 (66, 6%) were isolated from infections and 33.3% were isolated from colonization. multiple drug resistance was reported in (100%) of isolates, while (95%) and (45%) of isolates were resistant to vancomycin and ticoplanin respectively. VanA phenotype, vanA genotype was identified in (47.4%) of isolates, while vanB phenotype, vanA genotype was identified in (33.3%) of vancomycin resistant isolates.

Conclusion; VanB phenotype-vanA genotype was identified in (33.3%) of vancomycin resistant enterococcal isolates. To our knowledge it is the first identified incidence of such strains in Egypt and Africa.

Published: October 2019

Introduction: Whooping cough-like respiratory tract infections (WCLRTI) caused by factors other than the Bordetella pertussis are available. Clinical picture is difficult to differentiate between the B. pertussis and viral respiratory infections.

Methodology: Eighty-five patients with the diagnosis of WCLRTI were divided into 3 groups. Group 1 involved patients with pertussis shown by nasopharyngeal aspirate culture (NAC) and/or PCR. Group 2 consisted of patients who B. pertussis was not detected by NAC however, clinicians still evaluated them as potential patients of pertussis. Group 3 involved patients with the diagnosis of WCLRTI and those with VRTI detected by antigen detection/PCR.

Results: Patients with pertussis had longer duration of the symptoms prior to admission. Paroxysmal cough, whooping, vomiting after coughing, cyanosis, apnea, seizures and abdominal hernias were more common in patients with pertussis. Fever, wheezing, tachypnea, retraction, fine crackles and rhonchi were more common in Group 3. Chest radiographs of patients in Group 3 revealed more bronchopneumonic infiltration, increased aeration, and atelectasis. CRP (C-reactive protein) and ESR (erythrocyte sedimentation rate) were significantly higher in Group 3. Of the patients 43.6% had no pertussis vaccination due to being < 2 months in age and 29.4% had 1 dose.

Conclusions: Pertussis should be thought in differential diagnosis of children with complaints of episodes of paroxysmal cough, cough accompanied by gasping, vomiting after coughing; with leukocytosis, lymphocytosis and a normal chest X-ray. The majority of children with pertussis infection are those who have not had the opportunity for vaccination.

Published: October 2019

Introduction: Staphylococcal colonization is a risk factor for healthcare-associated infections, which are frequent in Neonatal Intensive Care Units (NICU). This study analyzed microbiology, epidemiology and clinical aspects of Staphylococcus spp. colonizing neonates.

Methodology: Nasal or periumbilical swabs were evaluated from 175 newborns admitted to a NICU of a Rio de Janeiro hospital from March to September 2009. Clinical data were obtained from the medical records. SCCmec typing and the mecA and Panton-Valentine Leukocidin (PVL) genes were detected by PCR. Clonal diversity was evaluated by pulsed-field gel electrophoresis.

Results: Staphylococcus spp. isolates were detected in 98 (56%) neonates, 66.3% of them had birth weight ≤ 2500 g, 62.2% were preterm (˂ 37 weeks) and the mean length of hospitalization was 14.9 days. Among the 133 isolates identified, 48.1% were S. epidermidis, 23.3% S. haemolyticus and 13.5% S. aureus. Methicillin-resistant Staphylococcus isolate was detected in 77.6% of neonates. The methicillin-resistant S. aureus isolates carried the SCCmec type IV, while 94.6% of S. epidermidis and 85.7% of S. haemolyticus presented non-typeable cassettes. Among the S. aureus, 55.6% had PVL genes and the USA800 genotype was prevalent. Two genotypes of S. epidermidis and one of S. haemolyticus clustered 42.2% and 25.8% of the isolates, respectively. S haemolyticus colonization was associated with the use of parenteral nutrition and mechanical ventilation.

Conclusion: High rate of neonates colonized by methicillin-resistant Staphylococcus species and the permanence of clones circulating in the NICU highlight the importance for continuous and preventive surveillance in this high-risk population.

Published: October 2019

Introduction: Clostridium chauvoei (C. chauvoei) is an anaerobic, histotoxic Gram-positive, bacterium causing fatal myonecrosis in livestock with high mortalities. The disease is common in dairy animals, but little is known about the pathophysiology of the disease in exotic (non-native) animals kept under local conditions in Pakistan.

Methodology: Diagnosis of blackleg was made based on hematological and serum biochemical analysis, PCR, necropsy and histopathology.

Results: Clinically sick animals exhibited fever, lameness, subcutaneous gaseous swelling and edema particularly in hindquarter and front legs. Hematological analysis showed increases in erythrocyte sedimentation rate and reduces in number of red blood cells, packed cell volume, leukocytes and differential leukocyte count. Serum aspartate aminotransferase, lactate dehydrogenase, alkaline phosphates, alanine aminotransferase, urea, creatinine, creatine kinase, and creatinine phosphokinase were significantly (P < 0.05) higher in the infected animals. At necropsy, swelling areas contained straw-colored fluid with gas bubbles. The muscles were swollen, dark to black and exhibited crepitation sounds at the time of incisions with a rancid odor. Severe pulmonary edema, myocarditis along with petechial hemorrhages, as well as enlargement and congestion of liver and spleen have been observed. Microscopic examination revealed severe inflammatory reaction, edema, and disruption of the myofibrils. Examination of heart, spleen, liver, kidneys, intestine, and lungs showed congestion, severe inflammatory changes with neutrophilic infiltration and necrosis accompanied by dissociation of the normal tissue structure. PCR confirmed C. chauvoei in exudates and different samples of muscles.

Conclusion: The pathophysiology should be considered in diagnosis of blackleg. The disease is exist in the non-native cattle farms and biosecurity measures have to be elevated.

Authors: Pakchotanon Rattapol , Ye Justine Yang , Cook Richard J. , Chandran Vinod , Gladman Dafna D.
Published: October 2019

Objective.

We aimed to determine the prevalence and incidence, and to identify the factors associated with liver abnormalities in patients with psoriatic arthritis (PsA).

Methods.

From a longitudinal cohort study, we identified PsA patients with either elevated serum transaminase or alkaline phosphatase levels or liver disease after the first visit to the PsA clinic (cases). Controls were subjects from the same cohort who never had such abnormalities or liver disease. Cases and controls were matched 1:1 by sex, age at the first clinic visit, and followup duration; variables at the onset of the first appearance of liver test abnormality associated with liver abnormalities were identified using univariate logistic and multivariate logistic regression analyses.

Results.

Among 1061 patients followed in the PsA clinic, 343 had liver abnormalities. Two hundred fifty-six patients who developed liver abnormalities after the first visit were identified as cases, and 718 patients were identified as controls. The prevalence of liver abnormalities was 32% and the incidence was 39/1000 patient-years where there were 256 cases over 6533 total person-years in the PsA cohort. Liver abnormalities were detected after a mean (SD) followup duration of 8.3 ± 7.8 years. The common causes of liver abnormalities were drug-induced hepatitis and fatty liver. Independent factors associated with liver abnormalities were higher body mass index (BMI), daily alcohol intake, higher damaged joint count, elevated C-reactive protein, and use of methotrexate, leflunomide, or tumor necrosis factor inhibitors.

Conclusion.

Liver abnormalities are common among patients with PsA and are associated with higher BMI, more severe disease, and certain therapies.
Comparison of Effect on Sicca Symptoms of Anticentromere Antibody–positive Sjögren Syndrome and Primary Sjögren Syndrome Alone
Authors: Li Yifan , Bookman Arthur A.M.
Published: October 2019

Objective.

To determine whether positive anticentromere antibody (ACA) serology affects the severity of sicca symptoms in patients with primary Sjögren syndrome (pSS).

Methods.

Evaluation to detect subjective and objective sicca symptoms included questionnaires, physical examination, and pathology. Cases of pSS were classified according to the 2002 American-European Consensus Group (AECG) criteria. All patients were evaluated for presence of anti-Ro, anti-La, and ACA serology. Patients with pSS were categorized into ACA+ SS and ACA–SS. The groups were compared for measures of severity of oral and ocular sicca.

Results.

The pSS group had 446 patients, of whom 26 were ACA+ SS. Subjective ocular sicca measured 7.0 ± 2.4 (out of 10) in ACA+ SS and 6.4 ± 2.6 in ACA–SS (p = 0.197). Objective ocular sicca measured 3.2 mm ± 1.8 mm/5 min in ACA+ SS and 4.2 mm ± 4.4 mm/5 min in ACA–SS (p = 0.038). Subjective oral sicca measured 8.5 ± 1.4 in ACA+ SS and 6.7 ± 2.4 in ACA–SS (p < 0.001). Objective oral sicca measured 0.1 ml ± 0.2 ml/15 min in ACA+ SS and 0.4 ml ± 1.0 ml/15 min in ACA–SS (p < 0.001). Only 35% of ACA+ patients with SS were anti-Ro–positive or anti-La–positive compared with 77% of the ACA–patients with SS (p < 0.001). There was no significant difference in minor salivary gland fibrosis or focus scores between ACA+ SS and ACA–patients with SS.

Conclusion.

ACA+ SS is associated with more severe objective ocular sicca and more severe subjective and objective oral sicca compared to ACA–SS. The majority of ACA+ patients with SS meet AECG criteria for pSS despite negative serology for anti-Ro/La antibodies.
Relationship between Gout and Diabetes Mellitus after Acute Pancreatitis: A Nationwide Cohort Study
Authors: Cho Jaelim , Dalbeth Nicola , Petrov Maxim S.
Published: October 2019

Objective.

After acute pancreatitis, individuals often have low-grade inflammation, and subsequently develop metabolic sequelae such as post-pancreatitis diabetes mellitus (PPDM). Although numerous studies have investigated the relationship between gout and type 2 diabetes, little is known about the relationship between gout and PPDM. The aim was to investigate the associations between gout and PPDM.

Methods.

Using nationwide pharmaceutical dispensing data linked to hospital discharge data in New Zealand, gout and PPDM were identified among individuals after first episode of acute pancreatitis between January 1, 2007, and December 31, 2015. Multivariable Cox regression analyses were conducted, adjusting for age, sex, ethnicity, social deprivation index, alcohol consumption, tobacco smoking, comorbidities, medications (glucocorticoids, statins, and estrogens), and characteristics of acute pancreatitis.

Results.

A total of 10,117 individuals were included in the analysis of risk for gout and 9471 in the analysis of risk for PPDM. PPDM was significantly associated with a higher risk of gout in the overall cohort (adjusted HR 1.88, 95% CI 1.15–3.06) and women (2.72, 95% CI 1.31–5.65), but not in men (1.42, 95% CI 0.73–2.78). Preexisting gout was significantly associated with a higher risk of PPDM in the overall cohort (adjusted HR 1.58, 95% CI 1.04–2.41) and women (2.66, 95% CI 1.29–5.49), but not in men (1.31, 95% CI 0.78–2.20).

Conclusion.

The relationship between gout and PPDM is bidirectional in the post-pancreatitis setting. A history of gout is a risk factor of PPDM, particularly in women.
The ecology of resilience learning in ubiquitous environments to adverse situations
Authors: Martínez-Rodríguez Reyna-C. , Benítez-Corona Lilia
Published: October 2019

Primary education in Mexico is facing a growing set of challenges that the government has tried to counteract through the use of communication technologies (ICT) in formal education. While these efforts provide support for students and educators, there remains a need for a renewed and contextualized awareness that will re-conceptualize the adverse experiences of students and the importance of resilience in the context of the learning environment. The objective of this document is to give an account of the learning acquired by nine telesecondary students in a rural area of Hidalgo and the student’s benefits of building awareness about the ecology of learning. The paper highlights the process of re-envisioning their experiences that emerged from the various points of views shared in discussion. The study was triangulated by quantitative and qualitative phenomenological and hermeneutical analyses. It was organized into three stages and employed a survey, semi-structured interviews, focus groups and use of the Google-Classroom platform. The hermeneutical analysis of autobiographies and the use of technological resources enhanced the personal analysis of the experiences of the participants. These experiences generated learning that may often be invisible in formal education but can empower critical thinking, collaboration and autonomy of students to become aware of their learning and the scope of their social contribution.

La Educación Básica en México contempla desafíos crecientes a los que se enfrenta mediante el uso de Tecnologías de la Información y la Comunicación (TIC). Sin embargo, en la educación formal se requiere detonar una toma de conciencia crítica y contextualizada que rescate las experiencias del estudiantado para resignificar situaciones adversas, así como dar importancia a la resiliencia a partir de las ecologías del aprendizaje. El objetivo de este documento es dar cuenta de los aprendizajes ubicuos que adquirieron nueve estudiantes de telesecundaria en un contexto rural de Hidalgo y los beneficios de la concienciación de la propia ecología del aprendizaje. Se hace énfasis en el proceso de resignificación que emergió a través de las diferentes aristas de comunicación. El estudio presenta resultados de un caso abordado con una metodología mixta por medio de una triangulación de información multifuente, cuantitativa y cualitativa fenomenológica con análisis hermenéutico, organizada en tres etapas, mediante un cuestionario, entrevistas semiestructuradas, grupos focales y uso de la plataforma Google Classroom. El análisis hermenéutico de las autobiografías y el uso de recursos tecnológicos potenció el análisis personal de experiencias generadoras de aprendizajes quizá invisibles en la educación formal, pero que pueden empoderar el pensamiento crítico, la colaboración y autonomía del estudiantado para la toma de conciencia de sus propios aprendizajes y el alcance de su aportación social a lo largo de su vida.
NEW WAY TO DETERMINE THE NAVIGATION AREA AND RESTRICTIONS ON WEATHER CONDITIONS FOR HIGH-SPEED MEGA YACHTS
Authors: Kanifolskyi O O
Published: October 2019

Several different versions of the Rules governing the navigation areas for small vessels currently exist. For example, various categories of vessels are proposed in International Standards ISO, European Union Directives and the Rules of various classification societies (GL, BV, RINA, Shipping Register of Ukraine and others). These regulatory documents contain various names of navigation areas and various values of permissible wave height characterizing the category of the vessel. Some Rules offer formulas for calculating the maximum height of a significant wave that a ship can meet in a voyage. The need to compare the existing requirements of various Rules, as well as to propose a new way of calculating permissible wave heights, which will determine the effective operation of the vessel, are actual tasks. The new way of calculation will be based on a comparison of the total energy of the wave and the kinetic energy of the vessel.
Spatial Modelling of Migration Decision-Selectivity in the Klang Valley Region, Malaysia
Authors: Rashid Mohd Fadzil Abdul
Published: October 2019

In the era of global urbanization, migration phenomena—particularly urban-to-urban migration—is one of the key drivers of urban development. This has led to a higher demand for spatial-social and spatial-economic activities, tremendously spurring the changes in demographic, size, and urban socio-economics. However, many researchers agree that this phenomenon is quite difficult to understand, particularly destination choices, due to complexity in migration behavioral factors. Inspired by this, this article attempts to demonstrate the capability of the ‘MGP model', the so-called ‘migration potential model'—a GIS-based multicriteria decision analysis approach, which incorporates migration decision-selectivity factors—for spatial migration modelling in the Klang Valley, Malaysia. Empirically tested, the MGP model, intended to be an advanced approach in migration analysis, GIS, and MCDA applications that provides urban planners with information about the areas that will be the centers of potential migration, will look at locations and expected levels. Finally, this article concludes with a discussion on the advantages of the MGP model, particularly for urban planning purposes and suggestions for further research.
Learning Path Recommendation System for Programming Education Based on Neural Networks
Authors: Saito Tomohiro , Watanobe Yutaka
Published: October 2019

Programming education has recently received increased attention due to growing demand for programming and information technology skills. However, a lack of teaching materials and human resources presents a major challenge to meeting this demand. One way to compensate for a shortage of trained teachers is to use machine learning techniques to assist learners. This article proposes a learning path recommendation system that applies a recurrent neural network to a learner's ability chart, which displays the learner's scores. In brief, a learning path is constructed from a learner's submission history using a trial-and-error process, and the learner's ability chart is used as an indicator of their current knowledge. An approach for constructing a learning path recommendation system using ability charts and its implementation based on a sequential prediction model and a recurrent neural network, are presented. Experimental evaluation is conducted with data from an e-learning system.

Authors: Nicholas Howard , Ng Wan
Published: October 2019

The vast majority of adolescents own and use mobile devices on a daily basis for learning and other everyday activities. Mobile digital literacy is a term that captures the various capabilities that these young people have to interact effectively and safely with information and people in virtual environments, as well as to sustain their formal and informal learning across time and space as they develop into independent, self-directed lifelong learners. As part of understanding adolescents' mobile digital practices, this research developed a framework for investigating the students' mobile digital literacy. This research used a quantitative methodology and adapted a generic digital literacy framework to investigate Years 7-10 Australian students' perceptions of their ability to use mobile technology for learning and everyday activities. The results show that the framework can effectively capture students' perceptions of themselves as having high levels of mobile digital literacy in all the three components (technical, cognitive, and social-emotional) of the digital literacy framework. The implications are discussed.

Authors: Shukla Shipra , Kumar Mahesh
Published: October 2019

The global routing performance is essential for the services provided by the internet applications on the Internet. Border Gateway Protocol (BGP) is the extensively used routing protocol for the autonomous systems which constructs the internet. The reduction in convergence time is a crucial challenge for BGP. The past studies confirm that the Minimum Route Advertisement Interval (MRAI) decreases the convergence time. However, most of the approaches are focused on finding the optimum MRAI value. The techniques to implement the MRAI timers are less addressed by the researcher in compare to finding the optimum MRAI value. The implementation of reusable MRAI timers for large networks is critical at different load conditions. Therefore, this article presents the novel approach Optimized MRAI timer in a large network which reduces the convergence time. The proposed approach reduces the end-to-end delay, the number of exchanged updates message, and convergence time of BGP events and enhances the number of delivered packets in compare to related techniques.

Authors: Park Jin Yong , Thangam Dhanabalan
Published: October 2019

To understand customer repurchase intention in online stores, the present study has evolved with three variables: customer trust, loyalty, and satisfaction. A theoretical model was also developed to examine customer repurchase intention towards online shopping. The observation unit of this research is online stores and the analytical unit is the customers who have been purchasing grocery products via online. A random sampling technique was used to select the respondents and who are easily accessible. The data was collected from 645 online customers in Seoul. The data was analyzed with a structural measurement equation model by using Partial Least Square 3.0. Outcomes of study showed that, customer satisfaction and trust were the significant predictors of customer repurchase intention. The effect of customer loyalty towards repurchase intention seems to be very low. Hence, online retailers have advised to concentrate more on the activities needed to increase customer loyalty and to purchase more.

This study examines how the number of choices offered on a website influences consumers' internal states (affective and cognitive responses) and their approach/avoidance behavior during online apparel shopping. Focus-group and questionnaire data collection methods with a 3 (number of choices) by 3 (presentation formats) factorial experimental design were employed. The theoretical frameworks, “choice overload” and “online store atmospherics and shopper response,” were applied. A total of 382 usable responses were collected. Although the interaction proposed in the study was not statistically significant, the findings of the study show that the effect of choice overload may not only influence the in-task generated responses but also have a deeper and long-lasting impact on the online consumer behavior. The respondents react to the large choice set on the basis of feelings and emotions (affective responses), and these responses ultimately lead to a subsequent attitude and approach behavior.

This study investigated the most common challenges of human-computer interaction (HCI) while using electronic health records (EHR) based on the experience of a large Russian medical research center. The article presents the results of testing DSS implemented in the mode of an additional interface with the EHR. The percentage of erroneous data for two groups of users (with and without notifications) is presented for the entire period of the experiment and the weekly dynamics of changes. The implementation of CDSS in the supplemented interface mode of the main medical information system (MIS) has had a positive effect in reducing user errors in the data. The results of users' survey are presented, showing a satisfactory evaluation of the implemented system. This study is part of a larger project to develop complex CDSS on cardiovascular disorders for medical research centers.

Aging causes loss of muscle strength, especially on the lower limbs, resulting in a higher risk of injuries during functional activities. To regain mobility and strength from injuries, physiotherapy prescribes rehabilitation exercise to assist the patients' recovery. In this article, the authors survey the existing work in exercise assessment and state identification which contributes to innovating the biofeedback for patient home guidance. The initial study on a machine-learning-based model is proposed to identify the 4-state motion of rehabilitation exercise using wearable sensors on the lower limbs. The study analyses the impact of the feature extracted from the sensor signals while classifying using the linear kernel of the support vector machine method. The evaluation results show that the method has an average accuracy of 95.83% using the raw sensor signal, which has more impact than the sensor fused Euler and joint angles in the state prediction model. This study will both enable real-time biofeedback and provide complementary support to clinical assessment and performance tracking.

This article addresses the challenges of routing hole and network partitioning often experienced in hierarchical wireless sensor networks (WSNs). This developed model classifies network nodes into sets for effective energy management and formulates two cluster networks namely: switching and non-switching networks. Both networks are considered homogeneous and static WSNs and adopted approaches of residual energy, multi-hop and minimal distance as routing decision parameters. The switching network in addition introduces an energy switching factor as a major decision parameter for the switching of cluster head roles amongst cluster nodes. Network simulation was done using Truetime 2.0 and energy dissipation of the respective nodes and cluster heads was observed against a threshold. Results showed the introduction of the energy switching factor gave a significant energy balancing effect as nodes exhibited uniform energy dissipation. Furthermore, the residual energies for most nodes were above the threshold eliminating the possibility of the presence of routing hole and network partitioning.

A Parallel Neural Network Approach for Faster Rumor Identification in Online Social Networks
Authors: Srinivasan Santhoshkumar , Dhinesh Babu L D
Published: October 2019

The unprecedented scale of rumor propagation in online social networks urges the necessity of faster rumor identification and control. The identification of rumors in the inception itself is imperative to bring down the harm it could cause to the society at large. But, the available information regarding rumors in inception stages is minimal. To identify rumors with data sparsity, we have proposed a twofold convolutional neural network approach with a new activation function which generalizes faster with higher accuracy. The proposed approach utilizes prominent features such as temporal and content for the classification. This rumor detection method is compared with the state-of-the-art rumor detection approaches and results prove the proposed method identifies rumor earlier than other approaches. Using this approach, the detected rumors with 88% accuracy and 92% precision for experimental datasets is 5% to 35% better than the existing approaches. This automated approach provides better results for larger and scale-free networks.

Steganography is a widely-used technique for digital data hiding. Image steganography is the most popular among all other kinds of steganography. In this article, a novel key-based blind method for RGB image steganography where multiple images can be hidden simultaneously is described. The proposed method is based on Discrete Cosine Transformation (DCT) and Discrete Wavelet Transformation (DWT) which provides enhanced security as well as improve the quality of the stego. Here, the cover image has been taken as RGB although the method can be implemented on grayscale images as well. The fundamental concept of visual cryptography has been utilized here in order to increase the capacity to a great extent. To make the method more robust and imperceptible, pseudo-random number sequence and a correlation coefficient have been used for embedding and the extraction of the secrets, respectively. The robustness of the method is tested against steganalysis attacks such as crop, rotate, resize, noise addition, and histogram equalization. The method has been applied on multiple sets of images and the quality of the resultant images have been analyzed through various matrices namely ‘Peak Signal to Noise Ratio,' ‘Structural Similarity index,' ‘Structural Content,' and ‘Maximum Difference.' The results obtained are very promising and have been compared with existing methods to prove its efficiency.
La falsa analogia tra rifiuto-rinuncia alle cure e suicidio medicalmente assistito. Riflessioni bioetiche sull’ordinanza della Corte Costituzionale n. 207/2018
Authors: Da Re Antonio
Published: October 2019

Il saggio sviluppa alcune riflessioni di carattere bioetico, singolarmente carenti nella recente ordinanza della Corte Costituzionale n. 207/2018. Tale ordinanza è intervenuta sulla sospetta illegittimità costituzionale dell’art. 580 del codice penale, con riferimento al caso di Fabiano Antoniani, meglio conosciuto come DJ Fabo, che, accompagnato in Svizzera da Marco Cappato, aveva chiesto e ottenuto di porre termine alla propria vita attraverso il suicidio medicalmente assistito. Il saggio per un verso mette in luce come secondo la Corte l’incriminazione del reato di aiuto al suicidio non sia in generale contraria alla Costituzione; per un altro verso critica la giustificazione dell’aiuto medico al suicidio che la Corte propone, sia pure rispetto ad alcune situazioni eccezionali ed estreme. Tale giustificazione si basa sull’indebita presupposizione che non vi siano differenze sostanziali tra il rifiuto e la rinuncia alle cure da un lato e il suicidio medicalmente assistito dall’altro. Sulla base di tale assunto la Corte perviene alla proposta, assai discutibile, di modificare la recentissima legge n. 219/2017 su “Norme in materia di consenso informato e di disposizioni anticipate di trattamento”. Il saggio critica pertanto la fallacia logica della falsa analogia nella quale incorre l’ordinanza della Corte. Tale fallacia si sviluppa in quattro momenti, nei quali si fa valere un’equiparazione indebita tra concetti e situazioni tra loro ben differenti. I quattro momenti riguardano 1) il binomio concettuale uccidere – lasciar morire; 2) il significato di morte; 3) il significato del trattamento farmacologico; 4) il valore della relazione medico – paziente.
