An integrated analysis of critical factor selection and service quality evaluation for shopping platform services

Nowadays, online and television (TV) shopping platforms, such as the shopping platform service, are becoming extremely popular. Despite these technological advances, there are some disputes resulting from the misunderstanding between real products and virtual ones. Consequently, many traditional physical sellers have been transforming their businesses to sell goods on TV. In recent years, the development of internet — applied shopping, such as MOD (Multimedia on Demand) in Taiwan, has brought shopping platform services to another new milestone. Shopping platform services have no limitations in relation to showcase space and business closing times. Therefore, shopping platform services are becoming more important than ever. Understanding customers' attitudes about shopping platforms efficiently helps shopping platform service providers to improve their service qualities and increase their market size. In this study, a novel MCDM (Multiple Criteria Decision Making) approach is used to solve the decision of service quality for shopping platform services. By applying this analytical process, this study determines the critical factors of shopping platform services that customers care about and identifies the service aspects/criteria and their corresponding service strategy groups.
Oral and maxillofacial lesions in a Thai pediatric population: a retrospective review from two dental schools.

OBJECTIVE To determine the prevalence of oral and maxillofacial lesions in a Thai pediatric population. MATERIAL AND METHOD Oral biopsy records from pediatric patients between the ages of 0 and 15 years in the files ofFaculty of Dentistry, Mahidol University, and the files of Faculty of Dentistry, Khon Kaen University were reviewed. The patients were divided into three age groups, including 0 to 5, 6 to 10, and 11 to 15 years. Excluding the diagnosis of normal tissues, the oral and maxillofacial lesions were classified into nine categories. RESULTS Of 13,050 biopsied oral and maxillofacial lesions, 1,389 cases (10.6%) came from pediatric patients. The largest number of lesions was odontogenic cysts and tumors, followed by inflammatory and reactive lesions, and salivary gland pathology The top ten most prevalent lesions contributed 73% of all oral biopsies. The most common lesion was dentigerous cyst, followed by mucocele and pyogenic granuloma. CONCLUSION The vast majority of oral diseases in children were benign and related to either developmental or tissue reaction, while malignant lesions were found in a very small proportion of all oral biopsies.
Reduced E-cadherin expression is correlated with poor prognosis in patients with bladder cancer: a systematic review and meta-analysis

The prognostic significance of E-cadherin expression in bladder cancer (BC) has been elevated for years, but published results remain controversial and inconsistent. We thus performed a systematic review and meta-analysis to determine the association between E-cadherin expression and BC prognosis. We systematically searched PubMed, Embase, Cochrane Library, and Web of Science databases to identify eligible studies published until March 2017. On the basis of our inclusion and exclusion criteria, a total of 2,089 patients from 19 studies were eligible for final analysis. Our results showed that reduced E-cadherin expression in BC was associated with poor overall survival (hazard ratio [HR] = 2.73, 95% CI: 1.74–4.27, p < 0.001), poor progression-free survival (HR = 6.39, 95% CI: 3.48–11.73, p < 0.001), and poor recurrence-free survival (HR = 2.48, 95% CI: 1.68–3.64, p < 0.001). Moreover, reduced E-cadherin expression was significantly correlated with pathological T stage (T2-4 vs. Ta-1: risk ratio [RR] = 2.14, 95% CI: 1.70–2.71), metastasis (yes vs. no: RR = 1.68, 95% CI: 1.17–2.40), grade (3 vs. 1/2: RR = 1.58, 95% CI: 1.29–1.93), and carcinoma in situ (yes vs. no: RR = 1.68, 95% CI: 1.09–2.58). This meta-analysis suggested that reduced E-cadherin expression was associated with poor prognosis and advanced clinicopathological characteristics and can serve as a useful biomarker for the clinical management of BC.
Single‐step nested polymerase chain reaction for detection of different genotypes of hepatitis C virus

Hepatitis C virus (HCV) exhibits considerable sequence variability and circulates in the blood at extremely low levels. Current methods for detecting HCV RNA are based mostly on nested polymerase chain reaction (PCR), in which part of the first amplification product is reamplified in the second tube by an internal primer pair. A novel nested PCR method was developed in which the two successive amplification processes are carried out in the same tube with a single step of physical manipulation. Careful selection of highly conserved sequences of the 5′ noncoding region as primers enabled successful detection of all three major genotypes circulating in France, including the one with variation in this region. Retaining high sensitivity of the conventional nested PCR, the novel method reduced greatly the risk of carry‐over contaminations. It was also cost‐ and time‐saving. The one‐step nested PCR method is especially suitable for routine diagnosis of HCV infection in clinical laboratories. © 1995 Wiley‐Liss, Inc.
The eradication of leprosy: molecular modeling techniques for novel drug discovery

Introduction: Leprosy is a slowly progressing bacterial infection caused by Mycobacterium leprae. The World Health Organization recommended multidrug therapy (MDT) which is extremely effective and halts the progress of the disease. Even though the objective of eliminating leprosy as a public health problem has been achieved successfully, leprosy is not yet eradicated. Furthermore, the long-term use of MDT results in single- and multidrug resistance. Therefore, there is still a need for new drug discovery for leprosy. Areas covered: The authors explain the importance of discovery of new drug to leprosy and the significance of homology modeling to drug discovery. This review highlights the principle steps, applications, and the resources of homology modeling. Finally, the authors emphasize the application of different structure-based drug design (SBDD) approaches to design novel therapeutics for leprosy. Expert opinion: MDT has proved to be effective in controlling infection, with prevalence of leprosy now predominantly isolated to the developing countries. The emergence of single- and multidrug-resistant strains of M. leprae has, however, provided some concern with the need for newer antibacterial agents. Drug resistance can be overcome by multi-targeted therapy. SBDD approaches, which reported many successful drugs, depend predominantly on the three-dimensional (3D) structure of drug targets. As of 2013, only very few experimental structures are available for M. leprae proteins. Hence, SBDD, in leprosy research, relies heavily on homology modeling to predict the 3D structure of drug targets and to design better therapeutics.
Parameter estimation of moving target for stepped-frequency radar under temporal-correlated clutter

Proposed is a maximum likelihood (ML) estimation method to estimate the parameter of the moving target for high range resolution stepped-frequency radar in strong clutter background. In this study the temporal correlated clutter is used. By transmitting frequency-hopping waveform and using the spectrum density of the clutter, the method may accurately estimate the moving target parameter in strong clutter. Numerical experiments illustrate the effectiveness of the proposed method.

Suitability of the unidirectional approach for describing laser-driven terahertz emission

Over the past decade, the increasing potential of terahertz (THz) radiation has stimulated intensive efforts to develop efficient emitters based on the ionization of gases by ultrashort laser pulses [1]. In order to properly calibrate dedicated experiments, nonlinear propagation codes have to be particularly accurate to describe the low-frequency part of the pulse spectrum. Usually, solving full Maxwell models accounting for multiple ionization processes as well as optical and plasma nonlinear effects is computationally expensive when simulating long propagation ranges. Therefore, reduced models such as the Unidirectional Pulse Propagation Equation (uppe) [2] are often preferred, assuming that the forward propagating component conveys the major part of the laser energy. So far, no detailed numerical comparison has been performed to confirm the validity of this uppe approach, which is widely used in the scope of laser-driven THz generation [3]. Here, we examine by means of 1D simulations the differences occurring in the THz pulse spectra and fields when these quantities are described either by a full Maxwell-fluid (maxflu) model, encompassing both backward and forward propagations, or by its uppe approximation, modeling only the forward propagating wave.
Cardiovascular Risk Profile at the Onset of Psoriatic Arthritis: A Population‐Based Cohort Study

The role of cardiovascular disease (CVD) risk factors in psoriatic arthritis (PsA) is poorly understood. We examined the prevalence of CVD risk factors at initial onset of PsA and compared the observed incidence of CVD events with that predicted by the Framingham Risk Score (FRS) to determine its applicability in this patient population.
Importance of KPI in BI System, Case Study: Iranian Industries

In today’s competitive world, having an effective business intelligent (BI) system for monitoring and evaluation of industrial and product oriented organizations is vital. A perfect BI must help managers not only to speed up his decision making process; but also to increase quality of their decision. But how? One of the main specifications of an effective BI system is providing managers by correct format of information and at the correct time. Critical Success Factors (CSFs) are a kind of significant factors that must be considered in attaining an organization’s goal; and key performance indicators (KPIs) are a type of quantitative and measurable CSF; and one character of an effective BI is reflecting relevant and valid KPIs. This work focuses on recognizing managerial weakness of Iranian industries; based on overall national diagnosing method, weakness of Iranian industries has been recognized and highly recommend to industrial BI analyzers and producers to cover these areas by defining and designing relevant KPIs and dashboard to weakness areas which has importance for managers on BI system; as result of that BI by helping to growth of industry performance can satisfy product oriented company managers.
Design and analysis of a novel fault tolerant permanent magnet synchronous motor for aircraft application

This paper proposes a novel ten-phase permanent magnet synchronous motor, which is characterized by two stators and two rotors mounted on the same shaft. Each segment of the motor can be considered as an 8-pole/10-slot five-phase permanent magnet synchronous motor with the concentrated, single-layer, and alternative teeth wound winding. Therefore, the structure can effectively improve the fault isolation of the motor. In addition, the two segment of the proposed motor has a circumferential displacement of 4.5 mechanical angle, which is used to reduce the cogging torque. Furthermore, we analyze the influence of the key design parameters on the short-circuit current of the motor. Then a phase inductance design approach is proposed to restrain the short-circuit current of the motor by increasing the self-inductance. Finally, the fault tolerant system performance of the proposed motor is verified by both the finite element analysis of the electromagnetic field and the prototype motor. The simulation and experimental results show that the proposed motor has excellent fault tolerant capacity.

Nine-switch controlled induction motor drive with unity and leading power factor

Back to back (B2B) voltage source converter is used for HVDC system and ac drive system to control active-reactive power. In this paper reduced switch back to back converter is used for induction motor drive system which is operated in unity as well as leading power factor. Active and reactive power flow are independently controlled. The active power transfer is controlled by angle delta; where delta is angle between input phase voltage and rectifier fundamental voltage. Reactive power flow is controlled by controlling dc link capacitor voltage. DC link capacitor voltage is regulated using PI controller. Appropriate gate signals are generated adding dc-offset in sinusoidal pulse width modulation technique. Microchip dsPIC33EP256MU810 digital signal controller is used for generating gate signals for nine switch converter (NSC) made up of FGA25N120 IGBTs. MATLAB/Simulink and prototype experimental results are presented to validate proposed concept. By tracking overall industrial power factor; this NSC drive system can made to run at leading power factor improving overall industrial power factor.
Causes of death and renal tubular dysfunction in residents exposed to cadmium in the environment

Objectives: To clarify the causes of death of residents with renal tubular dysfunction induced by cadmium (Cd) in the environment. Methods: A 15 year follow up study was performed with the inhabitants living in the Cd polluted Kakehashi River basin in Japan. Standardised mortality ratios (SMRs) for causes of death, classified by ICD-9, were computed using the person-years method to investigate the excess mortality of subjects with urinary β2-MG (microglobulin) ⩾1000 μg/gCr. Mortality risk analysis was performed using Cox’s proportional model to compare mortality between subjects with urinary β2-MG ⩾1000 and <1000 μg/gCr, and to investigate the relationship between the degree of urinary β2-MG and mortality. Results: Excess mortality due to heart failure and cerebral infarction in both sexes, and nephritis and nephrosis in men, was observed among subjects with urinary β2-MG ⩾1000 μg/gCr. Significant increases in mortality risk for cerebral infarction in men and for malignant neoplasms in women with urinary β2-MG ⩾1000 μg/gCr were observed during the first five year observation period. For nephritis and nephrosis, the mortality risks for men and women with urinary β2-MG ⩾1000 μg/gCr significantly increased over the 15 year observation period. The mortality risks for heart failure and cerebral infarction increased in proportion to the increased urinary β2-MG in both sexes. Increased mortality risks for nephritis and nephrosis were identified in the subjects with urinary β2-MG ⩾10000 μg/gCr in both sexes. Conclusion: Renal tubular dysfunction induced by Cd affected the causes of death, and mortality for heart failure, cerebral infarction, and nephritis and nephrosis was increased among inhabitants living in a Cd polluted area in Japan. In women, cancer mortality may have been increased while Cd pollution was ongoing.
A new horizon for organizational change and development scholarship: Connecting planned and emergent change

Research on organizational change and development is limited in how it addresses the processes that encompass change initiatives. In this chapter, we explore one dimension of these processes, the ways that research frames relationships between planned and emergent organizational change. We discuss five ways in which organization development (OD) research has addressed dichotomies between planned emergent change: separation, selection, integration, transcendence, and connection. We suggest that the most effective approach for considering this dichotomy is likely to be one that connects planned and emergent change over time. We further suggest that a means by which connection can usefully be created is through attention to a transient outcome of change attempts, the vitality associated with a change initiative at any moment. We present an example of how a connection frame was utilized in an extended research project. We also suggest an analytic framework and specific research methods consistent with a connection frame. In doing so, we suggest how the adoption of a connection frame by OD researchers and practitioners may lead to a more complete picture of organizational change.
Psychometric Properties of the MyotonPRO in Dementia Patients with Paratonia

Background: Paratonia is a distinctive form of hypertonia, causing loss of functional mobility in early stages of dementia to severe high muscle tone and pain in the late stages. For assessing and evaluating therapeutic interventions, objective instruments are required. Objective: Determine the psychometric properties of the MyotonPRO, a portable device that objectively measures muscle properties, in dementia patients with paratonia. Methods: Muscle properties were assessed with the MyotonPRO by 2 assessors within one session and repeated by the main researcher after 30 min and again after 6 months. Receiver operating characteristic curves were constructed for all MyotonPRO outcomes to discriminate between participants with (n = 70) and without paratonia (n = 82). In the participants with paratonia, correlation coefficients were established between the MyotonPRO outcomes and the Modified Ashworth Scale for paratonia (MAS-P) and muscle palpation. In participants with paratonia, reliability (intraclass correlation coefficient) and agreement values (standard error of measurement and minimal detectable change) were established. Longitudinal outcome from participants with paratonia throughout the study (n = 48) was used to establish the sensitivity for change (correlation coefficient) and responsiveness (minimal clinical important difference). Results: Included were 152 participants with dementia (mean [standard deviation] age of 83.5 [98.2]). The area under the curve ranged from 0.60 to 0.67 indicating the MyotonPRO is able to differentiate between participants with and without paratonia. The MyotonPRO explained 10-18% of the MAS-P score and 8-14% of the palpation score. Interclass correlation coefficients for interrater reliability ranged from 0.57 to 0.75 and from 0.54 to 0.71 for intrarater. The best agreement values were found for tone, elasticity, and stiffness. The change between baseline and 6 months in the MyotonPRO outcomes explained 8-13% of the change in the MAS-P scores. The minimal clinically important difference values were all smaller than the measurement error. Conclusion: The MyotonPRO is potentially applicable for cross-sectional studies between groups of paratonia patients and appears less suitable to measure intraindividual changes in paratonia. Because of the inherent variability in movement resistance in paratonia, the outcomes from the MyotonPRO should be interpreted with care; therefore, future research should focus on additional guidelines to increase the clinical interpretation and improving reproducibility.
Fibroblast growth factor-2-induced cardioprotection against myocardial infarction occurs via the interplay between nitric oxide, protein kinase signaling, and ATP-sensitive potassium channels

Fibroblast growth factor-2 (FGF2) protects the heart from ischemia–reperfusion (I-R) injury via a vast network of protein kinases. In the heart, downstream effectors of these FGF2-triggered signals have not yet been identified. It is hypothesized that nitric oxide (NO) signaling and ATP-sensitive potassium (KATP) channel activity are key effectors of protein kinases activated by FGF2-mediated cardioprotection. Hearts with a cardiac-specific overexpression of FGF2 (FGF2 Tg) were subjected to I-R injury in the absence or the presence of selective inhibitors of NO synthase (NOS) isoforms or sarcolemmal (sarcKATP) and mitochondrial (mitoKATP) KATP channels. Multiple NOS isoforms are necessary for FGF2-mediated cardioprotection, and nitrite levels are significantly reduced in FGF2 Tg hearts upon inhibition of protein kinase C or mitogen-activated protein kinases. Likewise, sarcKATP and mitoKATP channels are important for cardioprotection elicited by endogenous FGF2. These findings suggest that FGF2-induced cardioprotection occurs via protein kinase-NOS pathways as well as KATP channel activity.
An Automatic Measurement Method for Absolute Depth of Objects in Two Monocular Images Based on SIFT Feature

Recovering depth information of objects from two-dimensional images is one of the very important and basic problems in the field of computer vision. In view of the shortcomings of existing methods of depth estimation, a novel approach based on SIFT (the Scale Invariant Feature Transform) is presented in this paper. The approach can estimate the depths of objects in two images which are captured by an un-calibrated ordinary monocular camera. In this approach, above all, the first image is captured. All of the camera parameters remain unchanged, and the second image is acquired after moving the camera a distance d along the optical axis. Then image segmentation and SIFT feature extraction are implemented on the two images separately, and objects in the images are matched. Lastly, an object’s depth can be computed by the lengths of a pair of straight line segments. In order to ensure that the most appropriate pair of straight line segments are chosen, and also reduce computation, convex hull theory and knowledge of triangle similarity are employed. The experimental results show our approach is effective and practical.
South Africa's real business cycles: The cycle is the trend

This paper tests the `cycle is the trend' hypothesis. We investigate how far permanent and transitory productivity shocks can account for the dynamics observed in the South African business cycle over the period 1946--2014. By estimating a standard small open economy real business cycle model and its financial frictions augmented counterpart, we show that permanent productivity shocks are more important than transitory ones in explaining this country's business cycle fluctuations. This finding supports the `cycle is the trend' hypothesis in the South African business cycle. The model with financial frictions successfully mimics the downward-sloping high autocorrelation of trade balance to output ratio observed in the data, whereas the benchmark model produces a flat autocorrelation function. Financial frictions such as country risk premium shocks help to explain the fluctuations in investment and in the trade balance to output ratio.
