Application of a New Non-Invasive Skin Cholesterol Detection Technology in Atherosclerosis Screening

Background: Establishing a high-accuracy and non-invasive method is essential for evaluating cardiovascular disease. Skin cholesterol is a novel marker for assessing the risk of atherosclerosis and can be used as an independent risk factor for early assessment of atherosclerotic risk.Methods: we propose a non-invasive skin cholesterol detection method based on absorption spectroscopy. Detection reagents specifically bind to skin cholesterol and react with indicator to produce colored products, the skin cholesterol content can be obtained through absorption spectrum information of colored products detected by noninvasive technology. Gas chromatography is used to measure cholesterol extracted from the skin to verify the accuracy of the noninvasive test method. A total of 163 subjects were divided into normal group(n=58), disease group (n=26) and risk group(n=79). All subjects underwent noninvasive skin cholesterol test. The diagnostic accuracy of the measured value was analyzed by receiver-operating characteristic (ROC) curve.Results: The proposed method is able to identify porcine skin containing gradient concentration of cholesterol and the values measured by non-invasive detection method were significantly correlated with gas chromatography measured results (r=0.9074, n=73, p<0.001). We further evaluated the method on patients with atherosclerosis and high risk population as well as normal group, patients and high risk atherosclerosis group exhibited higher skin cholesterol content than normal group (all P<0.001). The area under the ROC curve for distinguishing Normal/Disease group was 0.8243(95% confidence interval, 0.7165 to 0.9321), however, the area under the ROC curve for distinguishing Normal/Risk group was 0.8488(95% confidence interval, 0.7793 to 0.9182). Conclusions: The method demonstrated its capability of detecting different concentration of skin cholesterol. This non-invasive skin cholesterol detection system may potentially be used as a risk assessment tool for atherosclerosis screening, especially in a large population.
Is depression associated with the risk of cardiovascular disease or vice versa?

The comorbidity between cardiovascular disease (CVD) and depression has been observed for many years. Several biological and behavioral hypotheses have been proposed to explain this comorbidity. However, the underlying common mechanisms are still unclear. Evidence suggests a bidirectional relationship between depression and CVD. Inflammation has been implicated in the etiology of both depression and CVD. In this review, we aim to increase awareness for CVD and depression comorbidity and provide some insights about the possible role of inflammation.
Engaging Medical Students During Covid-19 – Challenges and Novel Opportunities for Clinical Training

Introduction: The COVID-19 pandemic has disrupted undergraduate clinical training in an unprecedented manner. With face-face student-patient interaction severely curtailed and hands-on training limited, the pandemic has upended experiential learning in a major way. Methods: The aim of this review was to examine the challenges faced and actions taken by medical schools and explore opportunities to overcome the loss of clinical training due to constrains by the public health measures to the COVID-19 crisis. The relevant literature was searched in PubMed, and Google Scholar using specific keywords, e.g., “COVID-19 “medical education,” “challenges,” and “opportunities. ” Results: Four themes were explored; initial response, mitigation measures, innovative solutions and future plans. Halting undergraduate clinical training was widespread except in a few countries where student’s graduation was fast-tracked to serve the national healthcare workforce or assigned to nonclinical work. The loss of experiential learning was replaced by successfully transitioning to emergency remote online teaching through lectures, videos, quizzes and webinars. These are perceived as stopgap measures and falls short of replacing the authentic face to face learning in a clinical environment. Several innovative immersive methods were showcased using telehealth and virtual reality technologies and found to be useful and meaningful solutions to the loss of clinical interactions in the circumstances. Although these are attractive technological solutions, it is unlikely to be adopted in low resource setting until cost and training issues are resolved. Future plans will need to take the new-normal post covid environment into consideration and embrace the emergent technology to mitigate against further disruption. Conclusions: Significant widespread disruption to medical education has impacted clinical learning and delayed graduation. The rapid institutional response has mitigated the impact and kept students educationally engaged. The pandemic has highlighted that the immersive clinical experience in wards and interactive small group sessions are not easily replaceable. The challenge is to develop an innovative post-COVID medical education plan that will ensure a continuity in learning with academic competency.
Reduciendo la brecha de seguridad del IoT con una arquitectura de microservicios basada en TLS y OAuth2

El Internet de las cosas es una de las tendencias más prometedoras en la actualidad. La rapidez de su adopción, sin embargo, ha provocado ciertas brechas críticas en la seguridad de los sistemas involucrados. Este proyecto analizó el problema de seguridad de una manera amplia, pero enfocándose en entornos de tipo hogar inteligente, donde el uso de dispositivos con tecnologías ampliamente heterogéneas genera problemas en la autenticación con múltiples servicios, y en la confidencialidad de los datos, si la red llegara a verse comprometida. Para atacar estos problemas, se juntaron tecnologías de última generación como OAuth2 y TLS, entre otras, junto a una metodología arquitectural de microservicios de acoplamiento ligero, para generar una arquitectura IoT segura y de amplio alcance, respaldada y validada por una implementación de referencia. La división en capas funcionales permite que tanto los dispositivos y sensores fijos como aquellos móviles, puedan acoplarse al sistema de manera transparente y fluida. El esquema de seguridad estructurado en tres niveles incrementales permite que cada equipo pueda integrarse al que mejor se adapte tanto a sus recursos computacionales como al tipo de información que debe entregar o consumir. Los resultados muestran la flexibilidad de la solución y la solidez del esquema de seguridad presentado.
Biochar properties: Transport, fate, and impact

ABSTRACT Biochar is the name given to charcoal produced from pyrolyzed biomass with the purpose to add into soils to enhance soil properties and sequestrate carbon. Biochar has been a very popular research topic and a large amount of scientific literature has been produced in the last decade. Papers show biochar production from almost any type of biomass available using diverse types of thermochemical processes which have variations in technology, design, and conditions. All this variability in biomass feedstock and production has made biochar a very heterogeneous product, making it difficult to understand the biochar characteristics and qualities and what are the benefits and risks of its application in soils. This review presents a comprehensive vision of biochar properties, and their impact when biochar is applied to soils. To better understand this impact, biochar-collected data were classified in six types according to the main biomass used in its production, and divided into two thermochemical treatments: convectional pyrolysis methods and Hydrothermal Carbonization (HTC). Four biochar properties were studied: (i) physical and structural characteristics, (ii) chemical properties, (iii) agronomical properties, and (iv) contaminants. Outcomes of this review suggest that biochar can be a good soil amendment with capacity to enhance physical, chemical, and agronomic soil qualities. Nevertheless, results show the current lack of appropriate methodological analytical determination of some of the biochar characteristics. This can mislead to erroneous biochar characterization which could lead to future environmental issues. The review of the data suggested that some types of biomass could be not suitable for biochar soil application due to high levels of contaminants, although the information about solubility and availability of these contaminants in many cases is not clear. A consistent methodology, protocol, or index to measure biochar carbon stability in soils was not found; data suggest that a small proportion of biochars would not be suitable for carbon sequestration in soils but they could have good agronomical properties—this finding suggested that biochar production can be customized based on its final use. However, before proceeding to recommend massive use of biochar in soil, more research is necessary to have enough knowledge and understanding of biochar properties to develop models to predict biochar transport, fate, and impact.

Efisiensi Penyerbukan oleh Penyerbuk Liar dan Lebah Tetragonula laeviceps pada Bunga Ranti dan Kacang Panjang

Insect pollination is an effort to increase the efficiency of fruit production on limited land. The research aimed to observe the activity and pollination efficiency of wild insects and Tetragonula laeviceps on black nightshade plants and yardlong beans using an intercropping system in Sukawangi Village, Sumedang Regency from September to January 2020. Observations were made at 08:00-15:00 WIB during the flowering period. Observations were made on the treatment of T. laeviceps application, open-pollination, and self-pollination, each treatment consisting of 100 black nightshade flowers and 100 yardlong bean flowers and analyzed using one-way analysis of variance (α = 0.05). Insect activity was measured based on flower handling time, foraging rate, visitation rate, and fruit set. Fruit quality was measured based on diameter, weight, length, and oBrix. The study recorded 3 visiting insect flowers in black nightshade and yardlong, which potentially act as a pollinator, with varying visit patterns in open-pollination. The highest fruit set efficiency of black nightshade occurred in the application treatment of T. laeviceps and yardlong beans in the open-pollination treatment. There was significant in oBrix of black nightshade fruit and yardlong beans, whereas self-pollination only yielded significantly longer fruit in yardlong beans. Thus, T. laeviceps could be used as one possible domesticated pollinator to improve fruit set efficiency and fruit quality of black nightshade and yardlong beans. Keywords: fruit quality, fruit set, insect activity
Okul Öncesi Eğitim Programının 21. Yüzyıl Becerileri ve STEAM Eğitimi Bağlamında İncelenmesi

In order for an individual to have good skills and holistic development, he/she needs to have a good education in early childhood years. The importance of early childhood, which forms the basis of an individual's education, is well-known. The quality and content of the program, which forms the basis of education given to children in early childhood, is important in this sense. In this study, it is aimed to examine the 2013 preschool education program in terms of 21st century skills and STEAM education. Document analysis, one of the qualitative research methods, was used in the research. Descriptive statistics method was used to analyze the data, and the qualitative analysis program MAXQDA was used. Within the 2013 Preschool Education Program, the basic principles, development characteristics, achievements and indicators of preschool education, planning, implementation, evaluation sections of pre-school education were examined. As a result of the research, it was found that 2013 pre-school education program is a communication-based program that focuses on character traits and competence, which are among the 21st century skills, but it is insufficient in terms of information technology and media literacy. However, it was seen that the program emphasized art education in the context of STEAM education, focused on science and mathematics, but had no content in engineering and design. In line with the results, it may be suggested to revise the 2013 preschool education program in the context of 21st century skills and STEAM.
Numerical Simulation of the Ignition of Fuel/Air Gas Mixtures Around Small Hot Particles

Abstract This study presents the simulation and detailed analysis of the ignition of initially quiescent fuel/air mixtures by small, stationary, laser-heated spherical particles. Our simulations cover a wide parameter space by varying the kind of fuel, stoichiometry, heating rate, radical surface destruction efficiencies as well as particle size. The results agree well with experimentally determined particle surface temperatures at the time of ignition over the whole range of parameters. The surface temperatures required for ignition strongly depends on the kind of fuel and increases in the order hydrogen, acetylene, ethylene, ethane, propane and methane. It also increases with decreasing particle size. By contrast, mixture stoichiometry and heating rate have a minor influence on the ignition temperatures. Comparisons with two-dimensional direct numerical simulations show that fast, but fully coupled one-dimensional simulations are sufficient to capture the details of the ignition event, permitting a systematic investigation for large number of conditions. At small particle radii (r≤2 mm) there exists a simple mapping of only two parameters, an apparent activation energy and a factor comprising thermo-physical properties of the gas phase that is able to estimate the particle surface temperature required for ignition. Such a map might be used for the safety assessment of ignition hazards by small hot particles as function of fuel, stoichiometry and particle size.
Investigation of the Exchange Kinetics and Surface Recovery of CdxHg1–xTe Quantum Dots during Cation Exchange Using a Microfluidic Flow Reactor

Detailed analyses of coupled photoluminescence, emission lifetime, and absorption measurements have been made on the products of cation exchange reactions between CdTe nanocrystals and Hg2+ salt/ligand solutions in a microfluidic flow reactor and capillary measurement cell to probe the reaction kinetics over the seconds to hours time scale and to establish the influence of the reaction conditions on the spatial distribution of the mixed cations within the resulting CdxHg1–xTe colloidal quantum dots. The establishment of the evolution of the radiative and nonradiative rates allowed the recovery of the emission quantum yield in CdxHg1–xTe quantum dots to be quantified to almost 50% and the necessary time scales to be determined for each set of reaction conditions. The reaction kinetics showed clear indication of a fast surface exchange process followed by a slower internal rearrangement of the cation distribution.
A review of Register Variation Online (Biber & Egbert, 2018) — Cambridge University Press

Register variation online is aimed at language researchers interested in registers available online. The study describes register variation in the searchable web, in other words, texts that are publicly available when doing a Google search. Biber and Egbert (2018) argue that previous studies in web registers have focused on registers that emerged online and that only exist in the web, for example, tweets or Facebook posts. Nevertheless, when conducting a Google search on a random word -horsethey found that these registers are not the ones most commonly found by internet users. They also argue that previous research has focused on analyzing only one registers at a time. Therefore, they set out to investigate the different registers that emerge from a Google search, in order to identify their linguistic patterns. To do so, they conducted a multi-dimensional (MD) analysis in a corpus of online registers. Multi-dimensional analysis (Biber 1988) is an approach in which constellations of linguistic features are identified based on statistical co-occurrence patterns in texts. These patterns are interpreted as ‘dimensions’ of variation that are associated with the shared communicative functions of the co-occurring features. MD analysis demonstrates that linguistic features do not co-occur by chance, but rather because of shared underlying communicative functions that in turn correspond to shared situational features of the texts (Goulart et al. 2020). The authors also use keyword and key feature analysis to explore the register differences encountered online. In chapter 1, Biber and Egbert (2018) motivate their study by first discussing how the internet has spread in the past years and how, consequently, different websites have emerged as more people have access to the internet. They mention that, as a consequence of the proliferation of new websites, there is a range of new registers that have not been studied and that might not be similar to printed registers. Thus, there is a gap in this field of research. The authors also argue that there are more web pages accessible online than there are items in the British Library and the Library of Congress; hence, it is important to study the linguistic characteristics of these texts that are readily available for users to access.

The Logistic NHE Distribution with Properties and Applications

: In this paper, we have presented a univariate three-parameter continuous distribution called Logistic NHE distribution. We have discussed some mathematical and statistical characteristics of the distribution like the probability density function, cumulative distribution function and hazard rate function, survival function, quantile function, the skewness, and kurtosis measures. The proposed distribution's model parameters are estimated with the help of three well-accepted estimation methods which are maximum likelihood estimation (MLE), least-square estimation (LSE), and Cramer-Von-Mises estimation (CVME) methods. The proposed distribution's goodness of fit, is also evaluated by fitting it in comparison with some other existing distributions using a real data set.
KONSTRUKSI SOSIAL ISLAM MODERAT JAMAAH MAIYAH MOCOPAT SYAFAAT PADA GENERASI MILENIAL DI YOGYAKARTA

Understanding moderate Islam is very important to millennial Muslim generations in Indonesia. Today, this millennial generation is threatened by exposure to radicalism and intolerance, such as environmental studies, reading books and the Internet. This paper is a phenomenological study of the recitation of the congregation of intercessors Maiyah mocopat to inculcate moderate Islamic understanding in the millennial generation in Yogyakarta. The externalization of moderate Islam towards the millennial generation is achieved by creating a comfortable and enjoyable learning environment. Activities that occurred during this interfaith prayer session included Al-Quran, Shalawatan, Group Discussions, delivery of resource materials, sharing, and events interspersed with Kyai Kanjeng music performances. The activity makes the millennial generation have an objective understanding (objectivation) about peaceful Islam, soothing Islam, and moderate Islam. The internalization of moderate Islam is carried through primary socialization and secondary socialization. Primary socialization is carried in the family environment with the exemplary method. Whereas secondary socialization is carried in educational institutions such as schools, recitals, including through interfaith recitation sessions which held every 17th of the month
Unpacking vulnerability in academic writing and publishing: a tale of two non-native English speaker scholars in China

ABSTRACT Adopting ‘vulnerability’ as an analytical lens and informed by a qualitative case study approach, the present study investigates two Chinese scholars’ academic writing and publishing practice. The findings reveal different sources and forms of vulnerability that influenced the participants’ professional engagements, social interactions and emotional experiences in academic writing and publishing. The findings also demonstrate how the participants developed their advanced academic literacy about writing and micropolitical literacy about publishing to cope with potential vulnerability, and went on to construct their preferred identities as academic researchers and writers. The paper ends with some practical implications on how to promote a supportive and sustainable publishing culture in higher education.
An Evaluation of Online Proctoring Tools

COVID’19 is hastening the adoption of online learning and teaching worldwide, and across all levels of education. While many of the typical learning and teaching transactions such as lecturing and communicating are easily handled by contemporary online learning technologies, others, such as assessment of learning outcomes with closed book examinations are fraught with challenges. Among other issues to do with students and teachers, these challenges have to do with the ability of teachers and educational organizations to ensure academic integrity in the absence of a live proctor when an examination is being taken remotely and from a private location. A number of online proctoring tools are appearing on the market that portend to offer solutions to some of the major challenges. But for the moment, they too remain untried and tested on any large scale. This includes the cost of the service and their technical requirements. This paper reports on one of the first attempts to properly evaluate a selection of these tools and offer recommendations for educational institutions. This investigation, which was carried out at the University of the South Pacific, comprised a four-phased approach, starting with desk research that was followed with pilot testing by a group of experts as well as students. The elimination of a tool in every phase was based on the ‘survival of the fittest’ approach with each phase building upon the milestones and deliverables from the previous phase. This paper presents the results of this investigation and discusses its key findings.
