  • J, Vol. 2, Pages 247-267: A Building-Block Approach to State-Space
           Modeling of DC-DC Converter Systems

    • Authors: Gernot Herbst
      First page: 247
      Abstract: Small-signal models of DC-DC converters are often based on a state-space averaging approach, from which both control-oriented and other frequency-domain characteristics, such as input or output impedance, can be derived. Updating these models when extending the converter by filters or non-trivial loads, or adding control loops, can become a tedious task, however. To simplify this potentially error-prone process, a modular modeling approach is being proposed in this article. It consists of small state-space models for certain building blocks of a converter system on the one hand, and standardized operations for connecting these subsystem models to an overall converter system model on the other hand. The resulting state-space system model builds upon a two-port converter description and allows the extraction of control-oriented and impedance characteristics at any modeling stage, be it open loop or closed loop, single converter or series connections of converters. The ease of creating more complex models enabled by the proposed approach is also demonstrated with examples comprising multiple control loops or cascaded converters.

  • J, Vol. 2, Pages 268-275: The Confidence of Undergraduate Dental Students
           When Undertaking Indirect Restorations

    • Authors: James Puryer, Shaikho Khalaf, Maryam Ilkhani
      First page: 268
      Abstract: The General Dental Council expects United Kingdom graduating dentists to be competent at providing crown and bridge treatments and graduating students should feel confident to undertake these treatments. The aim of this study was to explore the confidence of undergraduate dental students when providing crown and fixed dental prosthesis treatments. An anonymous questionnaire was distributed to all (n = 198) undergraduate students in Years 3 to 5 at Bristol Dental School. The questionnaire comprised confidence interval ranked responses, and respondents’ data was analysed using SPSS. The response rate was 76%. Undergraduate perception of confidence increased throughout the three years of study (p < 0.01). There was a strong association between the amount of exposure students had to certain treatment stages and their perceived confidence levels. Confidence levels may be increased further with increased clinical experience.

  • J, Vol. 2, Pages 276-299: Selected Lyrics of Bontok’s “Antoway,
           Ayoweng, and Chag-Ay” Songs: An Initial Stylistic Assessment

    • Authors: Jonnelle D. Fagsao
      First page: 276
      Abstract: Most of the studies of Bontok songs in Bontoc, Mountain Province, Philippines have focused on the need to preserve an aspect of the “Ifuntok” (people of Bontoc) society, but the major aim of this paper first proposes an understanding of the Tokwifi’s “Antoway”, Bacwaden’s “Ayyoweng”, and Khensay’s “Chag-ay”, commonly regarded as songs of the Bontoks during wakes and funerals, taking into consideration its intrinsic potential on literary themes and musicality. This paper then organizes the framework of Prototype and Relevance Theory and applies it to the selected songs found in the three collections. It attempts to express how prototype and relevance theory can improve not only a thematic analysis of the selected songs, but also the extra-textual interpretations that can be drawn from them. In doing so, it adds to the contemporary thoughtful understanding of Bontok indigenous tradition, as they are deceptively eliminated of the impression of the past, recontextualized in today’s literature and music curriculum, and associated in contemporary free issues and concerns in the Bontok community.

  • J, Vol. 2, Pages 300-325: Crypto Hash Algorithm-Based Blockchain
           Technology for Managing Decentralized Ledger Database in Oil and Gas

    • Authors: Lukman Adewale Ajao, James Agajo, Emmanuel Adewale Adedokun, Loveth Karngong
      First page: 300
      Abstract: This research work proposes a method for the securing and monitoring of petroleum product distribution records in a decentralized ledger database using blockchain technology. The aim of using this technique is to secure the transaction of distributed ledgers in a database and to protect records from tampering, fraudulent activity, and corruption by the chain participants. The blockchain technology approach offers an efficient security measure and novel advantages, such as in the transaction existence and distribution ledger management between the depot, transporter, and retailing filling station. Others advantages are transparency, immunity to fraud, insusceptibility to tampering, and maintaining record order. The technique adopted for this secure distributed ledger database is crypto hash algorithm-1 (SHA-1)-based public permissioned blockchain and telematics, while this telematics approach is an embedded system integrated into an in-vehicle model for remote tracking of geolocation (using Global Positioning System (GPS)), monitoring, and far-off data acquisition in a real-time. The scope of the data in the secure distributed ledger database (using blockchain) developed are identification (ID) of the tanker operator, Depot name, Source station ID, Destination station ID, Petroleum product volume, Transporter ID, and Geographic automobiles location. This system proved to be efficient, secure, and easy to maintain as it does not permit any individual for records tampering, but supports agreement of ~75% of participants in the chain to make changes.

  • J, Vol. 2, Pages 326-339: The Unique Immunoregulatory Function of
           Staphylococcus Aureus Lipoteichoic Acid in Dendritic Cells

    • Authors: Saito, Lin, Wu
      First page: 326
      Abstract: Background and objectives: Lipoteichoic acid (LTA) is a structural component of Staphylococcus aureus (S. aureus) that induces severe infection disease and skin inflammation such as atopic dermatitis (AD); the biological function of LTA is still unclear. Dendritic cells (DC) are important regulators in the immune system, and the cells ectopically recognize agents that have an influence on the host immune response. We aimed to reveal the DC-based immune response against LTA to understand the novel mechanism in S. aureus related acute skin inflammation. Materials and Methods: Different doses of LTA were applied on the epidermal barrier dysfunction mice in order to evaluate the epidermal thickness, DC activation, and subsequent immunological response such as effector T-cell (Teff) activation. In addition, bone marrow-derived dendritic cells (BMDCs) were also treated with LTA, and the immunoregulatory mechanism was investigated. Results: A low dose of LTA did not induce skin inflammation at all; however, a high dose of LTA induced severe skin inflammation on epidermalba rrier dysfunction mice. Those symptoms were correlated with the DC and Teff activation status. The low-dose treatment of LTA showed a suppressive effect in pro-inflammatory cytokine production via a Toll-like receptor 2 (TLR2)-dominant manner, and the effect was significant regarding the co-treatment with another stimulatory signal such as TLR4 by lipopolysaccharide (LPS). Meanwhile, a high-dose treatment of LTA completely abolished the suppressive effect of a low-dose treatment. This phenomenon was based on C-type lectin receptors (CLRs), because the high dose of LTA greatly enhanced the expression of CLRs in the activated DCs. Conclusions: DCs sensed the dose difference of LTA, and the mechanism contributed to regulating immune responses such as effector T-cell activation, which was directly correlated with inflammatory response. This finding might provide an understanding for the novel immunological effect of LTA and S. aureus pathogenesis under inflammation, as well as the mechanism of symbiosis.

  • J, Vol. 2, Pages 340-351: Chernobyl’s Lesser Known Design Flaw: The
           Chernobyl Liquidator Medal—An Educational Essay

    • Authors: Michael McIntire, John Luczaj
      First page: 340
      Abstract: The honorary Chernobyl Liquidator Medal depicts pathways of alpha, gamma, and beta rays over a drop of blood, signifying the human health impacts of the Chernobyl accident. A relativistic analysis of the trajectories depicted on the Chernobyl Liquidator Medal is conducted assuming static uniform magnetic and electric fields. The parametric trajectories are determined using the energies of alpha (α) and beta (β) particles relevant to the Chernobyl nuclear power plant accident and compared with the trajectories depicted on the liquidator medal. For minimum alpha particle velocity of 0.0512c, the beta particle trajectory depicted on the medal is highly unlikely to have come from a naturally occurring nuclear decay process. The parametric equations are used to determine the necessary beta energies to reproduce the depicted trajectories. This article documents the unfortunate misrepresentation of a famous scientific experiment on an honorary medal and illustrates the importance of better communication between artists and scientists.

           Management of Parkinson’s Disease'

    • Authors: António Moreira, Luís Carlos Matos, Ana Maria Conceição
      First page: 352
      Abstract: Parkinson’s disease (PD) is a progressive neurological disorder leading to loss of autonomy and a decline in quality of life. Qigong, a practice rooted in traditional Chinese medicine, has been positively reported on a variety of complaints of chronically ill patients and on gait imbalance in the elderly. PubMed and B-On databases were accessed during March 2018 to carry out an inventory of relevant scientific papers relating PD to Qigong. Fifteen articles were found and analyzed allowing us to highlight that: (1) in addition to medication, Qigong shows potential gains in PD management; (2) there is a stabilizing effect of motor symptoms and positive results in several frequent autonomy symptoms; (3) Qigong is highly accepted by patients, and is a cost-effective treatment that can be self-practiced, improving sleep quality, gait speed, functional mobility and quality of life, thus reducing the risk of falling; (4) Qigong improves muscle hardness, functional ability to walk, hand–eye coordination and balance. Despite the promising results, the limitations and the disparity of experimental designs of the included studies do not allow us to have a conclusive answer to the question whether Qigong benefits the management of PD or not.

  • J, Vol. 2, Pages 364-383: Examining Consumers’ Attitudes toward
           Gmarket Online Shopping

    • Authors: Ronald Baganzi, Geon-Cheol Shin, Shali Wu
      First page: 364
      Abstract: In this study, we examine the consumers’ attitudes toward Gmarket online shopping in Korea. We use a model to explain that consumers’ attitudes toward online shopping are influenced by psychological, personal, and technological characteristics. We hypothesize that three major behavioral beliefs; perceived trust (psychological), perceived benefits (personal), and perceived website quality (technological) influence consumers’ attitudes toward online shopping. A questionnaire was designed and administered by surveying the Gmarket online shoppers in Korea. A total of 338 valid responses were collected and Partial Least Squares (PLS) Structural Equation Modelling (SEM) was used for data analysis. The findings indicate that consumers’ online shopping attitudes are a function of perceived benefits, trust, and perceived website quality. We found that 57.9 percent of the variation in online shopping attitudes results from perceived benefits, trust, and perceived website quality. Trust was found to be the most important predictor of consumers’ online shopping attitudes. We offer academic and practical implications that are useful in designing e-marketing strategies for competing in the online shopping cyberspace market in Korea. We recommend for the replication of a similar model in other parts of the world like Uganda (Jumia), China (Taobao), Japan (Rakuten), and the United States of America (eBay).

  • J, Vol. 2, Pages 384-409: On Some New Neighborhood Degree-Based Indices
           for Some Oxide and Silicate Networks

    • Authors: Sourav Mondal, Nilanjan De, Anita Pal
      First page: 384
      Abstract: Topological indices are numeric quantities that describes the topology of molecular structure in mathematical chemistry. An important area of applied mathematics is the chemical reaction network theory. Real-world problems can be modeled using this theory. Due to its worldwide applications, chemical networks have attracted researchers since their foundation. In this report, some silicate and oxide networks are studied, and exact expressions of some newly-developed neighborhood degree-based topological indices named as the neighborhood Zagreb index ( M N ), the neighborhood version of the forgotten topological index ( F N ), the modified neighborhood version of the forgotten topological index ( F N ∗ ), the neighborhood version of the second Zagreb index ( M 2 ∗ ), and neighborhood version of the hyper Zagreb index ( H M N ) are obtained for the aforementioned networks. In addition, a comparison among all the indices is shown graphically.

  • J, Vol. 2, Pages 102-115: Concept, Possibilities and Pilot-Testing of a
           New Smartphone Application for the Social and Life Sciences to Study Human
           Behavior Including Validation Data from Personality Psychology

    • Authors: Christian Montag, Harald Baumeister, Christopher Kannen, Rayna Sariyska, Eva-Maria Meßner, Matthias Brand
      First page: 102
      Abstract: With the advent of the World Wide Web, the smartphone and the Internet of Things, not only society but also the sciences are rapidly changing. In particular, the social sciences can profit from these digital developments, because now scientists have the power to study real-life human behavior via smartphones and other devices connected to the Internet of Things on a large-scale level. Although this sounds easy, scientists often face the problem that no practicable solution exists to participate in such a new scientific movement, due to a lack of an interdisciplinary network. If so, the development time of a new product, such as a smartphone application to get insights into human behavior takes an enormous amount of time and resources. Given this problem, the present work presents an easy way to use a smartphone application, which can be applied by social scientists to study a large range of scientific questions. The application provides measurements of variables via tracking smartphone–use patterns, such as call behavior, application use (e.g., social media), GPS and many others. In addition, the presented Android-based smartphone application, called Insights, can also be used to administer self-report questionnaires for conducting experience sampling and to search for co-variations between smartphone usage/smartphone data and self-report data. Of importance, the present work gives a detailed overview on how to conduct a study using an application such as Insights, starting from designing the study, installing the application to analyzing the data. In the present work, server requirements and privacy issues are also discussed. Furthermore, first validation data from personality psychology are presented. Such validation data are important in establishing trust in the applied technology to track behavior. In sum, the aim of the present work is (i) to provide interested scientists a short overview on how to conduct a study with smartphone app tracking technology, (ii) to present the features of the designed smartphone application and (iii) to demonstrate its validity with a proof of concept study, hence correlating smartphone usage with personality measures.

           Reference to the Molecular Mechanisms

    • Authors: Pengxiang Zhu, Masahiro Sakanaka
      First page: 116
      Abstract: Red ginseng, as an effective herbal medicine, has been traditionally and empirically used for the treatment of neuronal diseases. Many studies suggest that red ginseng and its ingredients protect the brain and spinal cord from neural injuries such as ischemia, trauma, and neurodegeneration. This review focuses on the molecular mechanisms underlying the neuroprotective effects of red ginseng and its ingredients. Ginsenoside Rb1 and other ginsenosides are regarded as the active ingredients of red ginseng; the anti-apoptotic, anti-inflammatory, and anti-oxidative actions of ginsenosides, together with a series of bioactive molecules relevant to the above actions, appear to account for the neuroprotective effects in vivo and/or in vitro. Moreover, in this review, the possibility is raised that more effective or stable neuroprotective derivatives based on the chemical structures of ginsenosides could be developed. Although further studies, including clinical trials, are necessary to confirm the pharmacological properties of red ginseng and its ingredients, red ginseng and its ingredients could be promising candidate drugs for the treatment of neural injuries.

      Abstract: It is likely that tardive dyskinsesia is caused by the oxidation of dopamine in dopaminergic neurons. This oxidation produces oxygen radicals that damage neurons. Damage accumulates until tardive dyskinesia occurs. The use of dopamine D2 receptor inhibitors should be limited to the lowest doses for the shortest duration possible.

      Abstract: Peripheral arterial disease (PAD) is an atherosclerotic disease closely associated with high morbidity and mortality in cardiac events. Inflammation is crucial in atherosclerosis both at triggering and in progression. Numerous inflammatory biomarkers (cytokines, matrix metalloproteinases (MMPs), selectin, intracellular adhesion molecule (ICAM), vascular cell adhesion molecule (VCAM) C-reactive protein (CRP), fibrinogen) have been measured in atherosclerotic diseases including PAD. This paper summarizes the data on the inflammatory biomarkers for PAD pathophysiology and highlights the most useful markers in monitoring PAD outcomes.

           Democratic Republic of the Congo Are Not Associated with Nighttime Light

      Abstract: Maintaining records of artisanal and small-scale mining sites in developing countries requires considerable effort, so it would be beneficial if Earth observation data from space could assist in the identifying and monitoring of such sites. Artificial light emissions are common at industrial-scale mining sites and have been associated with small-scale illegal mining in some contexts. Here, we examine whether known artisanal and small-scale mining sites in the Democratic Republic of the Congo (DRC) are associated with observations of night light emissions by the Visible Infrared Imaging Radiometer Suite Day/Night Band (DNB). Light emissions from the mining sites were not observed: the radiance observed from the sites was near zero and nearly identical to that observed for a set of randomly-chosen locations in the same region. While it is the case that DNB night lights’ products provide useful data in other resource extraction contexts, they do not appear to be useful for identifying artisanal mining sites in the DRC.

    • Authors: Rafail Abramov
      First page: 162
      Abstract: The inconsistency between the time-reversible Liouville equation and time-irreversible Boltzmann equation has been pointed out by Loschmidt. To avoid Loschmidt’s objection, here we propose a new dynamical system to model the motion of atoms of gas, with their interactions triggered by a random point process. Despite being random, this model can approximate the collision dynamics of rigid spheres via adjustable parameters. We compute the exact statistical steady state of the system, and determine the form of its marginal distributions for a large number of spheres. We find that the Kullback–Leibler entropy (a generalization of the conventional Boltzmann entropy) of the full system of random gas spheres is a non-increasing function of time. Unlike the conventional hard sphere model, the proposed random gas system results in a variant of the Enskog equation, which is known to be a more accurate model of dense gas than the Boltzmann equation. We examine the hydrodynamic limit of the derived Enskog equation for spheres of constant mass density, and find that the corresponding Enskog–Euler and Enskog–Navier–Stokes equations acquire additional effects in both the advective and viscous terms.

      Abstract: Study of emotions has gained interest in the field of sensory and consumer research. Accurate information can be obtained by studying physiological behavior along with self-reported-responses. The aim was to identify physiological and self-reported-responses towards visual stimuli and predict self-reported-responses using biometrics. Panelists (N = 63) were exposed to 12 images (ten from Geneva Affective PicturE Database (GAPED), two based on common fears) and a questionnaire (Face scale and EsSense). Emotions from facial expressions (FaceReaderTM), heart rate (HR), systolic pressure (SP), diastolic pressure (DP), and skin temperature (ST) were analyzed. Multiple regression analysis was used to predict self-reported-responses based on biometrics. Results showed that physiological along with self-reported responses were able to separate images based on cluster analysis as positive, neutral, or negative according to GAPED classification. Emotional terms with high or low valence were predicted by a general linear regression model using biometrics, while calm, which is in the center of emotion dimensional model, was not predicted. After separating images, positive and neutral categories could predict all emotional terms, while negative predicted Happy, Sad, and Scared. Heart Rate predicted emotions in positive (R2 = 0.52 for Scared) and neutral (R2 = 0.55 for Sad) categories while ST in positive images (R2 = 0.55 for Sad, R2 = 0.45 for Calm).

      Abstract: Among many clustering algorithms, the K-means clustering algorithm is widely used because of its simple algorithm and fast convergence. However, the K-value of clustering needs to be given in advance and the choice of K-value directly affect the convergence result. To solve this problem, we mainly analyze four K-value selection algorithms, namely Elbow Method, Gap Statistic, Silhouette Coefficient, and Canopy; give the pseudo code of the algorithm; and use the standard data set Iris for experimental verification. Finally, the verification results are evaluated, the advantages and disadvantages of the above four algorithms in a K-value selection are given, and the clustering range of the data set is pointed out.

    • Authors: Ann Hemingway
      First page: 236
      Abstract: This paper presents the findings from a study of an equine assisted intervention (EAI), which is currently referred over 150 predominantly young people with mental health and behavioural problems each year. The young people are referred to this intervention when other services such as Child & Adolescent Mental Health Services (CAMHS) are not effective. Performing an exploratory study of implementation may be indicated when, there are few previously published studies or existing data using a specific intervention technique. This study showed some positive changes for participants across eight dimensions including; assertiveness, engagement with learning, calmness, planning, taking responsibility, empathy, communication and focus and perseverance. The equine intervention literature has shown mixed results across a variety of study designs and target groups, in terms of the gold standard of evidence, randomised controlled studies however the evidence currently is very limited. This study used a non-randomised sample, no control group and an unstandardised measurement filled out by those who refer young people to the intervention (social workers and teachers). The outcomes however from this exploratory study would suggest that a randomised control trial may be warranted and achievable.

  • J, Vol. 2, Pages 17-40: Ionic Imbalances and Coupling in Synchronization
           of Responses in Neurons

    • Authors: Seyed-Ali Sadegh-Zadeh, Chandrasekhar Kambhampati, Darryl N. Davis
      First page: 17
      Abstract: Most neurodegenerative diseases (NDD) are a result of changes in the chemical composition of neurons. For example, Alzheimer’s disease (AD) is the product of Aβ peptide deposition which results in changes in the ion concentration. These changes in ion concentration affect the responses of the neuron to stimuli and often result in inducing excessive excitation or inhibition. This paper investigates the dynamics of a single neuron as ion changes occur. These changes are incorporated using the Nernst equation. Within the central and peripheral nervous system, signals and hence rhythms, are propagated through the coupling of the neurons. It was found that under certain conditions the coupling strength between two neurons could mitigate changes in ion concentration. By defining the state of perfect synchrony, it was shown that the effect of ion imbalance in coupled neurons was reduced while in uncoupled neurons these changes had a more significant impact on the neuronal behavior.

           Scheme for the Development of Computer-Based Testing (CBT)-Items in
           Traditional Test Software

    • Authors: Thilo J. Ketschau, Janne Kleinhans
      First page: 41
      Abstract: Computer-based testing (CBT) is gaining importance for studies addressing the diagnosis of competencies, because it is possible to simulate authentic action situations and may reduce the effort of analyzing the data. This benefit is most important for the phase of item design. In this phase of assessment construction, the pattern of answers of a sample is used to draw conclusions on the functionality of the items. Currently, there are no standards for the encodement of items which consider the specifications of CBT-instruments. These specifications are, for example, the a posteriori non-variability of the coding, a lack of information when using conventional test scores and the need of standardization of different formats of items. Taking these specifications into consideration, this paper proposes and discusses a two-stage coding systematization for CBT-items. For this, a distinction between item-coding and answer-coding was done. The coding is discussed for single-section and multi-section formats as well as dichotomous and polytomous answer modes. Therefore, this paper is for users of CBT-instruments who want to achieve the optimal information value of their test results with efficient coding.

           in the Operating Room

    • Authors: Alexandre Hurstel, Dominique Bechmann
      First page: 50
      Abstract: The consultation of medical images, 2D or 3D, has a crucial role for planned or ongoing surgical operations. During an intervention, this consultation induces a sterility loss for the surgeon due to the fact that the classical interaction devices are non-sterile. A solution to this problem would be to replace conventional devices by touchless interaction technologies, thereby enabling sterile interventions. In this paper, we present the conceptual development of an intuitive “gesture vocabulary” allowing the implementation of an effective touchless interactive system that is well adapted to the specificities of the surgical context. Our methodology and its implementation as well as our results are detailed. The suggested methodology and its implementation were both shown to be a valid approach to integrating this mean of interaction in the operating room.

  • J, Vol. 2, Pages 65-83: Improved Rainfall Prediction Using Combined
           Pre-Processing Methods and Feed-Forward Neural Networks

    • Authors: Duong Tran Anh, Thanh Duc Dang, Song Pham Van
      First page: 65
      Abstract: Rainfall prediction is a fundamental process in providing inputs for climate impact studies and hydrological process assessments. Rainfall events are, however, a complicated phenomenon and continues to be a challenge in forecasting. This paper introduces novel hybrid models for monthly rainfall prediction in which we combined two pre-processing methods (Seasonal Decomposition and Discrete Wavelet Transform) and two feed-forward neural networks (Artificial Neural Network and Seasonal Artificial Neural Network). In detail, observed monthly rainfall time series at the Ca Mau hydrological station in Vietnam were decomposed by using the two pre-processing data methods applied to five sub-signals at four levels by wavelet analysis, and three sub-sets by seasonal decomposition. After that, the processed data were used to feed the feed-forward Neural Network (ANN) and Seasonal Artificial Neural Network (SANN) rainfall prediction models. For model evaluations, the anticipated models were compared with the traditional Genetic Algorithm and Simulated Annealing algorithm (GA-SA) supported by Autoregressive Moving Average (ARMA) and Autoregressive Integrated Moving Average (ARIMA). Results showed both the wavelet transform and seasonal decomposition methods combined with the SANN model could satisfactorily simulate non-stationary and non-linear time series-related problems such as rainfall prediction, but wavelet transform along with SANN provided the most accurately predicted monthly rainfall.

  • J, Vol. 2, Pages 84-101: The 2016 US Presidential Elections: What Went
           Wrong in Pre-Election Polls' Demographics Help to Explain

    • Authors: Rami Zeedan
      First page: 84
      Abstract: This study examined the accuracy of the various forecasting methods of the 2016 US Presidential Elections. The findings revealed a high accuracy in predicting the popular vote. However, this is most suitable in an electoral system which is not divided into constituencies. Instead, due to the Electoral College method used in the US elections, forecasting should focus on predicting the winner in every state separately. Nevertheless, miss-predicted results in only a few states led to false forecasting of the elected president in 2016. The current methods proved less accurate in predicting the vote in states that are less urbanized and with less diverse society regarding race, ethnicity, and religion. The most challenging was predicting the vote of people who are White, Protestant Christians, and highly religious. In order to improve pre-election polls, this study suggests a few changes to the current methods, mainly to adopt the “Cleavage Sampling” method that can better predict the expected turnout of specific social groups, thus leading to higher accuracy of pre-election polling.
