The use of 'Precision Teaching' in enhancing medical students’ dermatological diagnostic skills

Abstract BackgroundBackground Educators have been challenged to provide more effective dermatology teaching methods. Drawing from the discipline of Applied Behaviour Analysis, Precision Training (PT) (e.g. using flashcards during timed learning sessions) can promote fluency i.e. accuracy and speed in a particular skill. We aimed to determine the impact of PT on medical students’ dermatology diagnostic skills. MethodsMethods A between-groups controlled interventional study was conducted. Third year medical students were allocated to an intervention (PT + traditional teaching) or control (traditional teaching) group. For the PT group, we designed 50 dermatological image flashcards. Flashcard practice (using the Say All Fast Minute Each Day Shuffle method) took place 2-3 times/day and students’ data on accuracy recorded over 5 days. Pre / post-training tests were carried out to determine the impact of PT on students’ diagnostic skills. ResultsResults In total, 70 students (intervention group) / 65 (control group). Analysis of covariance was used to calculate the change score (comparing pre- and post-test). A statistically significant improvement of 8.8% (95% CIs; 4.9-12.7, p<0.001) was detected in the intervention group. ConclusionsConclusions The findings of this study demonstrated a positive effect of PT on medical students’ dermatology diagnostic skills. This study signals new pedagogical opportunities for PT in undergraduate dermatology teaching. the pre- and post- dermatology diagnostic tests. to self-guide their dermatological skill development in a timely and resource efficient manner. Dermatology PT has the potential of being integrated with other forms of traditional dermatological teaching methods in a blended fashion. The findings of this study warrant further research to determine the full potential of this educational method in dermatology and other areas of medical education. Developed from the discipline of Applied Behaviour Analysis, Precision Teaching (PT) is an educational method used to develop behavioural fluency, i.e. accuracy and speed in skill performance We aimed to determine the impact of PT on medical students’ dermatology diagnostic skills compared to traditional teaching methods. Our results indicate that PT had a positive impact on learners’ ability to describe and diagnose a range of important skin conditions. The use of PT in dermatology education shows promise in enhancing medical students’ dermatological diagnostic skills.
Exploring the nexus of green information technology capital, environmental corporate social responsibility, environmental performance and the business competitiveness of Thai sports industry firms

The prime objective of the current study is exploring the nexus of green information technology capital, environmental corporate social responsibility, environmental performance and the business competitiveness of Thai sports industry firms. The final sample of the study comprises of 434 respondents. Moreover, the study explains the way in which the competitiveness of business and environmental performance is increased through green information technology capital and environmental corporate and social responsibility. The SEM-PLS is used to analyses the data. The previous research studies did not incorporate the environmental performance, green issues of enterprise management, and competitiveness of business with reference to green IT capital. Therefore, to increase the investment on green IT capital by environmental corporate and social responsibility has been provided in this study. This ultimately improves the competitiveness of business and environmental performance. Moreover, a research framework has been developed for the competitiveness of business and environmental performance and for defining their association with the green IT capital and ECSR. It is found that the investment in structural capital support the organization in meeting the demand of market and this makes them bias towards investment in the relational and structural capital.
MEASURING TEST COVERAGE IN EMBEDDED SOFTWARE DEVELOPMENT BRANCHES

Most of the hardware products today, especially those that people interact with, are controlled by software. There are many devices with inbuilt software which many people do not bother to notice. Software may be critical in terms of strict quality requirements due to failures which enable risks of endangering the production and more importantly the lives of people. The testing team of Westermo Network Technologies AB faced a challenge with not being able to identify the coverage of tested cases in software. Identifying the coverage of total executed test cases enables the possibility of knowing the potential future quality of a software. By reaching such a stage a software will likely not suffer from failures due to higher quality, therefore the lives of people and the production at stake will not get harmed. The essential problem is that test cases are both tested and skipped, which makes it more difficult for the company to identify what has been actually tested and skipped. The purpose of this thesis is to identify and calculate the coverage of test cases, the process was mainly to understand the essence in the identification of executed test cases. The ethical aspect of putting people's lives at stake is what inspired us to investigate software failures. Software is typically tested before a release, therefore our investigation was to research testing process of software. When investigating test result over many days and test systems we developed a coverage calculator system which helps Westermo to decide and determine the release of tested software, either the software test result is acceptable for a release or not.
THz spectroscopic imaging using optical parametric generator

In this study, the spectral imaging system that we built using injection-seeded THz parametric generation and detection can successfully identify reagents through thicker material than the previously used thin envelopes. In 2003, we reported the first-ever development of a spectral imaging system using THz-wave parametric oscillator (TPO) [1]. At that time, the TPO had a dynamic range below four orders of magnitude, which enables it to identify reagents only through thin (0.1mmt) envelopes using spectral imaging. Recently, we have succeeded in the development of high power and high sensitivity THz wave spectral imaging system using injection-seeded THz parametric generation (is-TPG) and detection [2] as shown in Fig. 1. A dynamic range of 100 dB has been obtained, which is much higher than that of the 2003 TPO. The peak output power of is-TPG approached 50 kW by introducing a microchip YAG laser with shorter pulse width of 420ps. In the detection section of our system, THz-wave was converted back into near infrared beam by nonlinear optical wavelength conversion. We have realized ten orders of dynamic range using commercially available near infrared photo detector. Now we can detect drugs under much thicker obstacles than before using evolved is-TPG spectroscopic imaging system as shown in Fig. 2. Our evolved is-TPG system has potential applications in spectroscopic sensing and imaging of chemicals through obstacles [3] and nondestructive CT imaging of plastic/ceramic products [4]. We have also compared our is-TPG spectrometer and TDS (THz Time Domain Spectroscopy) for the purpose of drug detection through thick envelopes.
Correlation of Cd147 with pituitary adenoma invasiveness, size, and shape

The aim of this study was to elucidate a more convincing and precise relationship between CD147 expression levels with pituitary adenoma invasiveness, tumor size, and shape. Examining whether the suprasellar region or sphenoidal sinus was invaded, the present meta-analysis was conducted. A total of 11 eligible studies, with 686 patients, were included in the present meta-analysis. CD147 expression in pituitary adenoma tissues was positively associated with invasiveness (dichotomous: OR 5.971, 95% CI 2.375, 15.014; p < 0.001; continuous: SMD -2.228, 95% CI -2.831, -1.625; p < 0.001), tumor size (OR 2.700, 95% CI 1.690, 4.316; p < 0.001), and suprasellar invasion (OR 3.605, 95% CI 1.723, 7.543; p = 0.001). There was no significant correlation between CD147 and tumor shape (OR 1.547, 95% CI 0.321, 7.463; p = 0.587) or sphenoidal sinus invasion (OR 1.754, 95% CI 0.189, 16.296; p = 0.621). In conclusion, present results suggest that CD147 expression levels are associated with pituitary adenoma invasiveness. CD147 correlated to tumor size and suprasellar invasion rather than tumor shape and sphenoidal sinus invasion. CD147 may serve as a potential diagnostic marker or useful therapy target.
Equivalent crossed products of monoidal Hom-Hopf algebras

In this paper, we give a Maschke-type theorem for a Hom-crossed product on a finite dimensional monoidal Hom-Hopf algebra, and investigate a sufficient and necessary condition for two Hom-crossed products to be equivalent. Furthermore, we construct an equivalent Homcrossed system based on a same Hom-crossed product by using lazy Hom2-cocyle.
Steam Flow Pressure Reduction Valve Mass Flow Calculation

In this paper an analysis of the three different calculation methods for the steam mass low through the linear pressure reduction valve is presented. Two different makers developed their own mass low calculation method while one is following recommendation as per ISO standard calculation guidance. All three methods were varied and compared. For calculation model a superheated steam reduction valve was taken, which is reducing superheated steam pressure from 6 to 2 MPa, with ixed Kv value and with variations of the inlet superheated steam temperature from 310 to 280 °C.
B cell phenotype and function in granulomatosis with polyangiitis

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is strongly associated with autoantibodies against myeloperoxidase (MPO) and proteinase 3 (PR3). No clear consensus has been reached on the pathogenicity of these autoantibodies. Animal models for MPO-ANCA, in vitro data suggesting pathogenicity of ANCA, and one case of a neonate showing symptoms of vasculitis after transplacental transfer of MPO, argue in favour of a pathogenic role for ANCA. On the other hand, the presence of natural MPO and PR3 autoantibodies in healthy individuals, lack of a strong correlation between ANCA titers and disease activity, and the occurrence of ANCA-negative AAV patients argue against pathogenicity of ANCA. Recent papers have drawn attention to the possibility of epitope specificity defining ANCA pathogenicity. Certain MPO epitopes were found to be specific for active disease, and others remained present during remission or were also present in healthy individuals. One linear epitope, aa447-459, was not only exclusive for active disease, but also detected in the total Ig fraction of ANCA-negative patients, reactivity being masked in serum by ceruloplasmin. So, not all ANCA seems to be equal, some could be pathogenic while others are not. For development of an autoimmune response, a specific ANCA repertoire is required, which may occur through intra-molecular epitope spreading in patients.
Cartographer SLAM Method for Optimization with an Adaptive Multi-Distance Scan Scheduler

This paper presents the use of Google’s simultaneous localization and mapping (SLAM) technique, namely Cartographer, and adaptive multistage distance scheduler (AMDS) to improve the processing speed. This approach optimizes the processing speed of SLAM which is known to have performance degradation as the map grows due to a larger scan matcher. In this proposed work, the adaptive method was successfully tested in an actual vehicle to map roads in real time. The AMDS performs a local pose correction by controlling the LiDAR sensor scan range and scan matcher search window with the help of scheduling algorithms. The scheduling algorithms manage the SLAM that swaps between short and long distances during map data collection. As a result, the algorithms efficiently improved performance speed similar to short distance LiDAR scans while maintaining the accuracy of the full distance of LiDAR. By swapping the scan distance of the sensor, and adaptively limiting the search size of the scan matcher to handle difference scan sizes, the pose’s generation performance time is improved by approximately 16% as compared with a fixed scan distance, while maintaining similar accuracy.
Graphene-Based Heterogeneous Catalysis: Role of Graphene

Graphene, the reincarnation of a surface, offers new opportunities in catalytic applications, not only because of its peculiar electronic structure, but also because of the ease of modulating it. A vast number of proposals have been made to support this point, but there has been a lack of a systematic understanding of the different roles of graphene, as many other reviews published have focused on the synthesis and characterization of the various graphene-based catalysts. In this review, we surveyed the vast literature related to various theoretical proposals and experimental realizations of graphene-based catalysts to first classify and then elucidate the different roles played by graphene in solid-state heterogeneous catalysis. Owing to its one-atom thickness and zero bandgap with low density of states around Fermi level, graphene has great potential in catalysis applications. In general, graphene can function as a support for catalysts, a cover to protect catalysts, or the catalytic center itself. Understanding these functions is important in the design of catalysts in terms of how to optimize the electronic structure of the active sites for particular applications, a few case studies of which will be presented for each role.
SHAPE MEMORY MATERIALS AND THEIR APPLICATIONS IN AIRCRAFT MORPHING: AN INTROSPECTIVE STUDY

Smart materials are intelligent materials that are capable of responding to external stimulus, viz., heat, light, and chemical. Among the smart materials, there is a class of stimulus-responsive materials which are capable of recovering their original shape when subjected to even large loads and inelastic deformations. These materials are termed as shape memory materials. These materials are employed in a various disciplines due to their characteristic properties. In our study, we will enumerate the important class of shape memory materials i.e., shape memory alloys and shape memory polymers and their applications of shape memory materials in the field of aircraft morphing. A brief discussion of these materials will be provided along with the phenomenon of aircraft morphing. The study will contribute in providing an insight review of the shape memory materials being developed for aircraft morphing.
Optimization of the 2 ½ D Processing Method of Complex Parts, through a Predictive Algorithm for Controlling the Geometric Shape Deviations Resulting from Processing

This article intends to define a new methodology that allows the processing of complex surfaces in space through processing cycles, in parallel superposed planes—the variant known as generic processing in 2 ½ D—but with predictable control over the deviation from the geometric form of the surface to be processed. The novel methodology consists of identifying the optimal distances between the working planes and the corresponding successive positions so that the deviations from the resulting geometric form fall within the prescribed limits. It is also envisaged that the method will provide facilities in terms of the possibilities for evaluation of deviations from the given form of the surface, and keeping them under control by the stage of elaboration of the numerical control programs. The new optimization is designed to determine the maximum distances between successive processing planes and their position in space, depending on the spatial shape of the surface to be processed. Thus, the aim is to obtain a small number of processing planes with a favorable effect on productivity, but under conditions that respect the tolerances of the surface or the profile, a restriction that otherwise has a negative effect on the same process.
The treatment efficacy of vitamin D3 for heart failure patients: a meta-analysis of randomized controlled trials

Introduction: The efficacy of vitamin D3 for heart failure remains controversial. We conducted a systematic review and meta-analysis to explore the impact of vitamin D3 on heart failure patients. Methods: We searched PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through September 2018 for randomized controlled trials (RCTs) assessing the effects of vitamin D3 versus placebo on heart failure. This meta-analysis is performed using a random-effect model. The primary outcome is a change in left ventricular ejection fraction (LVEF). Secondary outcomes include 6 minute walking test (6MWT) change, 25-hydroxyvitamin D (25(OH)D) change, brain natriuretic peptide (BNP), hospitalization rate and mortality. Results: Eight RCTs are included in the metaanalysis. Overall, compared with the control group for heart failure, vitamin D3 supplementation results in improvement in LVEF (MD=7.89; 95% CI=7.17 to 8.60; P<0.00001), 6MWT change (MD=11.55; 95% CI=10.94 to 12.16; P<0.00001) and 25(OH)D (MD=47.03; 95% CI=31.68 to 62.38; P<0.00001), but has no significant effect on BNP (MD=-447.02; 95% CI=-1262.67 to 368.62; P=0.28), hospitalization rate (RR=1.64; 95% CI=0.37 to 7.20; P=0.51) and mortality (RR=1.12; 95% CI=0.77 to 1.64; P=0.55). Conclusions: Vitamin D3 supplementation can provide some benefits for heart failure patients.
The relationship between male pattern baldness and prostate cancer risk: a meta-analysis

Background: Both male pattern baldness and prostate cancer are age-dependent and androgen-related conditions. Many studies have investigated the relationship between male pattern baldness and prostate cancer risk, but have shown inconsistent results. Hence, we performed a meta-analysis to assess the correlation between male pattern baldness and prostate cancer risk. Material/Methods: A meta-analysis was conducted to evaluate the association of these two conditions. PubMed, Embase, and Medline were used to search the studies that considered the relationship between these two diseases through June 2017. OR and 95% CI were used to calculate the pooled risk with a fixed-effects model. Results: Ten studies that involved 5091 cases and 6423 controls were included in our study to assess the relationship between male pattern baldness and the risk of prostate cancer. No significant relationship between male pattern baldness and prostate cancer risk was found based on a summary OR (95% CI) of 1.06 (0.97, 1.16). However, in subgroup analysis, a significantly positive association between vertex pattern baldness and prostate cancer risk was found, with the pooled OR (95% CI) being 1.26 (1.12, 1.43). Frontal and frontal + vertex pattern baldness, however, were not associated with an increased risk of prostate cancer, with pooled OR (95% CI) of 1.03 (0.85, 1.24) and 1.05 (0.92, 1.20) respectively. Conclusions: This study suggests a significantly positive association between vertex pattern baldness and prostate cancer risk, but no significantly positive association between other types of male pattern baldness and prostate cancer risk. However, further studies are warranted to confirm these findings.
Stability and Thermal Properties Study of Metal Chalcogenide-Based Nanofluids for Concentrating Solar Power

Nanofluids are colloidal suspensions of nanomaterials in a fluid which exhibit enhanced thermophysical properties compared to conventional fluids. The addition of nanomaterials to a fluid can increase the thermal conductivity, isobaric-specific heat, diffusivity, and the convective heat transfer coefficient of the original fluid. For this reason, nanofluids have been studied over the last decades in many fields such as biomedicine, industrial cooling, nuclear reactors, and also in solar thermal applications. In this paper, we report the preparation and characterization of nanofluids based on one-dimensional MoS2 and WS2 nanosheets to improve the thermal properties of the heat transfer fluid currently used in concentrating solar plants (CSP). A comparative study of both types of nanofluids was performed for explaining the influence of nanostructure morphologies on nanofluid stability and thermal properties. The nanofluids prepared in this work present a high stability over time and thermal conductivity enhancements of up to 46% for MoS2-based nanofluid and up to 35% for WS2-based nanofluid. These results led to an increase in the efficiency of the solar collectors of 21.3% and 16.8% when the nanofluids based on MoS2 nanowires or WS2 nanosheets were used instead of the typical thermal oil.
The effect of prednisone acetate combined with cyclophosphamide on systemic lupus erythematosus and serum IL-4, IL-6, and IL-10 expressions

Objective: To investigate the efficacy of prednisone acetate combined with cyclophosphamide for the treatment of systemic lupus erythematosus and their effects on serum interleukin (IL)-4, IL-6, and IL-10. Methods: A total of 90 patients with systemic lupus erythematosus were randomly assigned into a control group and an observation group. The control group was treated with prednisone (n=45), while the observation group was given an additional cyclophosphamide (n=45). The serum levels of IL-4, IL-6, and IL-10 were measured by ELISA after 28 days of treatment. The changes in the IL-4, IL-6, and IL-10 expressions, efficacy and adverse reactions after treatment were compared between the two groups. According to the efficacy after 90 days of treatment, the patients were divided into two subgroups, the favorable efficacy subgroup (patients of markedly effective efficacy) and the poor efficacy subgroup (patients of effective and ineffective efficacy). The expressions of IL-4, IL-6, and IL-10 were compared between the two subgroups. A receiver operating characteristic curve was plotted to observe the predictive value of each indicator for efficacy. Results: There were no statistical differences in the baseline data between the two groups (all P>0.05). After treatment, the expressions of serum IL-4, IL-6, and IL-10 in the observation group were significantly lower than they were in the control group (all P<0.05). The total incidence of adverse reactions between the two groups was not significant (P>0.05). The clinical outcomes between the two groups were significantly different (P<0.05). The expressions of serum IL-4, IL-6, and IL-10 in the patients with favorable efficacy were significantly lower than those in the patients with poor efficacy (all P<0.05). The receiver operating characteristic curve analysis showed that the areas under the curve of IL-4, IL-6, and IL-10 were 0.703, 0.782, and 0.670, respectively. Conclusion: Prednisone acetate combined with cyclophosphamide can effectively improve the conditions of patients with systemic lupus erythematosus, and the expressions of IL-4, IL-6, and IL-10 in the serum can be used as potential indicators for the prediction of clinical efficacy.
