Indoor acoustic localization: a survey
Authors: Liu Manni , Cheng Linsong , Qian Kun , Wang Jiliang , Wang Jin , Liu Yunhao
Published: January 2020

Applications of localization range from body tracking, gesture capturing, indoor plan construction to mobile health sensing. Technologies such as inertial sensors, radio frequency signals and cameras have been deeply excavated to locate targets. Among all the technologies, the acoustic signal gains enormous favor considering its comparatively high accuracy with common infrastructure and low time latency. Range-based localization falls into two categories: absolute range and relative range. Different mechanisms, such as Time of Flight, Doppler effect and phase shift, are widely studied to achieve the two genres of localization. The subcategories show distinguishing features but also face diverse challenges. In this survey, we present a comprehensive overview on various indoor localization systems derived from the various mechanisms. We also discuss the remaining issues and the future work.

Authors: Tewabe Tilahun , Belachew Amare , Miskir Yihun , Mekuria Getnet
Published: January 2020

Background

Malnutrition with its constituents of protein energy malnutrition and micro-nutrient deficiencies continues to be a major health burden in low and middle-income countries. To end all forms of malnutrition, we need to address poverty, which is associated with the insecure supply of food and diversified nutrition. The objective of this study was to determine the level of dietary diversity and household food security among urban school-age children in Merawi town, Ethiopia.

Methods

A community based cross-sectional study was conducted in Merawi town among 422 households having school age children from April 1 to June 15, 2018. The association between dietary diversity and determinants was assessed using binary logistic regression analysis. Socio-demographic, maternal and child related variables; food security and diversity determinants were studied.

Results

The overall level of good dietary diversity was 91.7%, i.e.; 8.3% had a low, 59.1% had a good, 32.6% had better dietary diversity, respectively. Most households (95.2%) were secured with food access. The factors associated with good dietary diversity were the age of the child [AOR = 0.31 (0.14, 0.70)], and access to information [AOR = 3.18 (1.07,9.47)].

Conclusion

The prevalence of good dietary diversity was relatively high. Among different socio-cultural and economic factors studied, age of the child and access to information were the factors associated with dietary diversity. Increasing maternal and child awareness towards good dietary diversity practices through the mass media (radio and Television) and working with mothers with early school-age children to improve dietary diversity are recommended.
The term structure, leading indicators, and recessions: evidence from Switzerland, 1974–2017
Authors: Stuart Rebecca
Published: January 2020

This paper studies the predictive power for recessions of the slope of the Swiss term structure using monthly data for 1974–2017. Dynamic probit models indicate that the term structure contains information useful for predicting recessions for horizons up to 19 months. Whether the economy is currently in recession or not is also useful for forecasting recessions. These relationships prove stable over the sample. Robustness tests indicate that the KOF business course indicator and some monetary aggregates contain different information from the term structure which can improve the in- and out-of-sample fit of the model.

Authors: Hamdy Omar , Raafat Sara , Saleh Gehad A. , Awny Shadi , Shebl Abdelhadi M. , Hegazy Mohammed A.
Published: January 2020

Background

Ameloblastoma is the commonest odontogenic tumour of epithelial origin with a high incidence for developing local recurrence. We present a patient who developed local recurrence in both soft tissue and bone graft 17 years after the initial presentation.

Case presentation

A 75-year-old female with a previous history of right hemimandibulectomy and rib reconstruction for ameloblastoma in 1999 presented to our centre with a large cystic mouth floor swelling, biopsy from which revealed recurrent ameloblastoma. The patient underwent excision of the recurrent mass en bloc with the cystic swelling through oral and cervical approaches. The patient was discharged after 5 days with an uneventful postoperative course and with a free 2-year follow-up from further recurrence.

Conclusion

Ameloblastoma is a locally aggressive tumour for which wide local excision with adequate margins is the best management approach. Recurrence of ameloblastoma even after adequate resection is not uncommon, and its management is considered a surgical challenge. A very long time may pass between the initial presentation and the development of recurrence.
Endoscopic versus open harvesting of radial artery for CABG
Authors: Fouly Mohamed Abdel Hafez
Published: January 2020

Background

Endoscopic harvest of the radial artery avoids long forearm incisions and has better cosmesis compared to the open technique. The objective of this study was to compare the short-term results and wound-related complications of endoscopic radial artery harvest versus open technique.

Results

From 2013 to 2017, 800 patients had coronary artery bypass grafting; 88 patients of them had radial artery harvesting (11%). Two groups were included in the study according to the surgeon preference, endoscopic radial harvest (group 1, n = 30; 3.75% of total CABG patients) and open harvest (group 2, n = 58; 7.25% of total CABG patients). Group 1 had more males (25 (83.33%) vs. 35 (60.34%); p = 0.028). There was no difference in the preoperative comorbidities between both groups. The duration of the harvest was significantly longer in group 1 (median 40 min ranges from 38 to 42 min vs. 49 min ranges from 47 to 52 min in groups 1 and 2, respectively; p < 0.001). The operative time was longer in group 1 (median 302.5 min ranges from 295 to 310 min vs. 277 min ranges from 273 to 280 min in groups 1 and 2, respectively; p < 0.001). The hospital stay in the endoscopic radial artery harvest group was significantly shorter than that of open technique (median 7 days ranges from 6 to 7 days vs. 7.5 days ranges from 7 to 9 days; p < 0.001). There was no significant difference in the postoperative complications between both groups. One case (3.3%) was transformed from the endoscopic to open technique due to uncontrolled bleeding. Endoscopic technique was associated with more patients presenting with hand numbness (6 cases; 20% versus 3 cases 5.2%) and radial nerve injury (2 cases; 6.6% versus none), while open technique showed more cases of local hematoma (8 cases; 13.8% versus 1 case; 3.3%) and wound infection (6 cases; 10.34% versus none); p > 0.05.

Conclusion

Endoscopic radial artery harvest is associated with shorter harvest time and shorter hospital stay. Endoscopic radial artery harvest is a safe technique with good short-term outcomes. Longer follow-up is recommended.
Association between childhood trauma and multimodal early-onset hallucinations
Authors: Medjkane François , Notredame Charles-Edouard , Sharkey Lucie , D'Hondt Fabien , Vaiva Guillaume , Jardri Renaud
Published: January 2020

Previous reports suggest that adverse events during childhood could be related to an array of psychiatric problems. Here, we question the relationship between childhood traumatic experiences and the sensory complexity of hallucinations in a cohort of 75 children and adolescents. We evidence a positive link between the number of sensory modalities involved in hallucinations and history of childhood trauma, even after controlling for the co-occurrence of suicidal ideation or the number of ICD-10 diagnoses. These findings support initiatives in which a routine exploration of traumatic events in childhood is performed when multimodal hallucinations are present.

Duplex kidney formation: developmental mechanisms and genetic predisposition
Authors: Kozlov Vladimir M. , Schedl Andreas
Published: January 2020

Congenital abnormalities of the kidney and urinary tract (CAKUT) are a highly diverse group of diseases that together belong to the most common abnormalities detected in the new-born child. Consistent with this diversity, CAKUT are caused by mutations in a large number of genes and present a wide spectrum of phenotypes. In this review, we will focus on duplex kidneys, a relatively frequent form of CAKUT that is often asymptomatic but predisposes to vesicoureteral reflux and hydronephrosis. We will summarise the molecular programs responsible for ureter induction, review the genes that have been identified as risk factors in duplex kidney formation and discuss molecular and cellular mechanisms that may lead to this malformation.

Authors: Fadhilah Khusnul , Wahyuono Subagus , Astuti Puji
Published: January 2020

Background: Breast cancer is a major health problem for women globally. Many attempts have been promoted to cure cancer by finding new anticancer medicines from natural resources. Despite the richness of biodiversity discovered, there are some natural resources that remain unexplored. Fruit peels of Duku (Lansium domesticum Corr.) are rich with compounds that may have the potential to be developed as anticancer drugs. This study aimed to isolate cytotoxic compounds from the fruit peels of L. domesticum and assess their cytotoxic nature against T47D cells.

Methods: Powdered peels were macerated with ethyl acetate and the filtrate was evaporated to give EtOAc extract A. Dried extract A was triturated with n-hexane to give n-hexane soluble fraction B and insoluble fraction C. The cytotoxic nature of these three  samples were assessed using MTT assay using T47D cells and doxorubicin as a control.

Results: Fraction C that showed the smallest IC50 (25.56 ± 0.64μg/mL) value compared to  extract A and fraction B. Fraction C was further fractionated by vacuum liquid chromatography to give 6 subfractions. Subfraction 2 showed a single compound based on thin layer chromatography, and this compound was identified as Lamesticumin A on the basis of its spectroscopic data. Lamesticumin A demonstrated cytotoxic activity against T47D cell lines with an IC50 value of 15.68 ± 0.30µg/mL.

Conclusions: Further research is needed to investigate the potential of the natural compound Lamesticumin A derived from L. domesticum fruit peel as an anticancer therapy.

Published: January 2020

Background: Myanmar has the third highest number of people living with HIV in Southeast Asia behind Indonesia and Thailand. The independent predictors of comprehensive HIV knowledge among general population are not known.

Methods: In this nationally representative study, we adopted a cross-sectional design using secondary data from the Myanmar Demographic and Health Survey (2015-16). We included all women and men aged 15-49 years who participated in the survey. We have provided weighted estimates as the analyses were weighted for the multi-stage sampling design. We used modified Poisson regression with robust variance estimates model to identify independent predictors of comprehensive knowledge.

Results: Of 17,622 analyzed, 3,599 (20.4%, 95% CI: 19.7, 21.1) had comprehensive knowledge of HIV. Late adolescents, those with less than a high school education, those involved in agriculture and the poorest two quintiles were less likely to have comprehensive knowledge of HIV.

Conclusion: In Myanmar, comprehensive knowledge of HIV among the general population needs to be improved and we identified certain independent predictors that could be specifically targeted by the national programme.
CARACTERIZAÇÃO DAS POLÍTICAS EDUCACIONAIS NO BRASIL A PARTIR DA SISTEMATIZAÇÃO DO ESTADO DA ARTE
Authors: Estevão Larissa Dos Santos , Silva Katharine Ninive Pinto
Published: January 2020

O estudo versa sobre o estado da arte no campo das políticas educacionais considerando o cenário político-econômico do país e sua inserção na totalidade internacional, em um contexto de intensas transformações na sociedade. As reflexões e contribuição encontradas estão fundamentadas nos aportes teóricos do marxismo e apontam para três categorias: Imperialismo; Agenda Internacional para a Educação e Paradigmas na Educação. A partir dessas, compreende-se que o imperialismo, por meio dos organismos internacionais, utiliza a educação como um instrumento tanto para preparar o trabalhador com habilidades e competências exigidas pelo mercado como para prevenir distúrbios sociais diante da intensificação da exploração do capital. Nesse contexto, a pesquisa científica no campo da educação assume papel crucial na crítica aos caminhos pelos quais se têm conduzido a escola pública, objetivando a construção de uma educação científica e popular.

Light-assisted drying for anhydrous preservation of biological samples: optical characterization of the trehalose preservation matrix
Authors: Young Madison A. , Furr Daniel P. , McKeough Riley Q. , Elliott Gloria D. , Trammell Susan R.
Published: January 2020

Protein-based drugs have been developed to treat a variety of conditions and assays use immobilized capture proteins for disease detection. Freeze-drying is currently the standard for the preservation of proteins, but this method is expensive and requires lengthy processing times. Anhydrous preservation in a trehalose amorphous solid matrix offers a promising alternative to freeze-drying. Light assisted drying (LAD) is a processing method to create an amorphous trehalose matrix. Proteins suspended in a trehalose solution are dehydrated using near-infrared laser light. The laser radiation accelerates drying and as water is removed the trehalose forms a protective matrix. In this work, LAD samples are characterized to determine the crystallization kinetics of the trehalose after LAD processing and the distribution of amorphous trehalose in the samples. These characteristics influence the long-term stability of the samples. Polarized light imaging revealed that LAD processed samples are stable against crystallization during low-humidity storage at room temperature. Scanning white light interferometry and Raman spectroscopy indicated that trehalose was present across samples in an amorphous form. In addition, differential scanning microcalorimetry was used to measure the thermodynamic characteristics of the protein lysozyme after LAD processing. These results demonstrate that LAD does not change the properties of this protein.
Tissue imaging depth limit of stimulated Raman scattering microscopy
Authors: Hill Andrew H. , Manifold Bryce , Fu Dan
Published: January 2020

Stimulated Raman scattering (SRS) microscopy is a promising technique for studying tissue structure, physiology, and function. Similar to other nonlinear optical imaging techniques, SRS is severely limited in imaging depth due to the turbidity and heterogeneity of tissue, regardless of whether imaging in the transmissive or epi mode. While this challenge is well known, important imaging parameters (namely maximum imaging depth and imaging signal to noise ratio) have rarely been reported in the literature. It is also important to compare epi mode and transmissive mode imaging to determine the best geometry for many tissue imaging applications. In this manuscript we report the achievable signal sizes and imaging depths using a simultaneous epi/transmissive imaging approach in four different murine tissues; brain, lung, kidney, and liver. For all four cases we report maximum signal sizes, scattering lengths, and achievable imaging depths as a function of tissue type and sample thickness. We report that for murine brain samples thinner than 2 mm transmissive imaging provides better results, while samples 2 mm and thicker are best imaged with epi imaging. We also demonstrate the use of a CNN-based denoising algorithm to yield a 40 µm (24%) increase in achievable imaging depth.
Vectorial birefringence imaging by optical coherence microscopy for assessing fibrillar microstructures in the cornea and limbus

Published: January 2020

The organization of fibrillar tissue on the micrometer scale carries direct implications for health and disease but remains difficult to assess in vivo. Polarization-sensitive optical coherence tomography measures birefringence, which relates to the microscopic arrangement of fibrillar tissue components. Here, we demonstrate a critical improvement in leveraging this contrast mechanism by employing the improved spatial resolution of focus-extended optical coherence microscopy (1.4 µm axially in air and 1.6 µm laterally, over more than 70 µm depth of field). Vectorial birefringence imaging of sheep cornea ex vivo reveals its lamellar organization into thin sections with distinct local optic axis orientations, paving the way to resolving similar features in vivo.
Relating wavefront error to visual acuity in pre- and post-LASIK eyes: a comparison of methods
Authors: Dehoog Edward , Van Dine Robert , Fitzgerald-Dehoog Lindsay , Schwiegerling Jim
Published: January 2020

Contrast threshold and visual Strehl ratio methods are used to predict visual acuity from wavefront error for a sample population of pre- and post-LASIK patients. Relative error (in logMAR) between predicted and measured visual acuity values are computed for each method and compared using paired t-tests. Differences in aberration data between pre- and post-LASIK eyes are then evaluated. The visual acuity prediction using visual Strehl proved to be more accurate for pre-LASIK patients than contrast threshold. However, both methods are comparable for post-LASIK patients.
Molecular spin–photovoltaic device based on a graphene nanoflake
Authors: Zamani Sara , Farghadan Rouhollah
Published: January 2020

We generate a spin-polarized current in a hexagonal zigzag graphene nanoflake (hZGNF) by integrating the photovoltaic and spin-dependent transport effects. We consider three different hZGNF configurations and simulate their spin–photovoltaic properties using two probe models in the presence of ferromagnetic contacts as well as the magnetization of zigzag edges. Our results reveal acceptable spin-dependent quantum efficiency, full optical spin polarization, and good optically induced magnetoresistance up to 900%, which can be modified by adjusting the photon energy, by varying the configuration, and also by introducing monovacancy. Interestingly, switching the magnetization of ferromagnetic contacts can approximately invert the spin characteristic of the photocurrent, and so the sign of optical spin polarization. Our findings may provide an efficient way to enhance radiation-induced magnetoresistance in carbon-based molecular junctions.
Fiber motion-insensitive fiber-based polarization-sensitive optical coherence tomography for optic axis determination
Authors: Lu Zenghai , Liu Cheng
Published: January 2020

Polarization-sensitive optical coherence tomography (PS-OCT) is widely
used to image fibrous biological tissues, providing additional image
contrast compared to intensity-based OCT, including birefringence and
optic axis orientation information. Here a theoretical and
experimental analysis of the effect of the system fiber on
determination of sample optic axis orientation using a previously
reported algorithm based on the angle between Stokes vectors on the
Poincaré sphere in fiber-based PS-OCT experimentally confirms that the
algorithm only works correctly when the parameters of the system fiber
are kept constant during the imaging acquisition of each frame. To
extend the use of the algorithm to situations in which the parameters
of the system fiber are varied among A-scans or image frames, which is
true when the OCT probe scanning does move the sample arm fiber, we
propose the use of polarization maintaining fiber (PMF) with a special
polarization axis orientation as the sample arm fiber for extracting
sample optic axis orientation using fiber-based PS-OCT systems. The
use of the PMF makes the system insensitive to variations of the
sample fiber birefringence for determining optic axis orientation by
automatically removing the offset ambiguity from each A-scan. We
demonstrated by using a computer evaluation model that the proposed
method is capable of extracting the relative optic axis orientation
correctly when the PMF birefringence is varied among A-scans due to
external disturbances to the system fiber, provided that the
polarization axis orientation (slow or fast) of the PMF is kept
constant during the measurement.

Deploying performance poetry in dispelling HIV and AIDS stigma: An applied theatre approach
Authors: Moyo Cletus , Sibanda Nkululeko
Published: January 2020

Abstract The article is based on an applied theatre project facilitated by Cletus Moyo at the University of the Witwatersrand, Johannesburg, South Africa from 2009 to 2010. We argue that performance poetry deployed within an applied theatre paradigm has the potential to unlock
the silence around HIV and AIDS issues in a way that opens up these issues for discussion and makes them accessible for exploration, even in contexts where speaking about these issues is taboo. The project targeted young people belonging to the age group that is most heavily hit by the HIV
and AIDS pandemic. Notably, the young generation is also more open to performance poetry as an artform, making it more appropriate in dealing with issues affecting them. Performance poetry is a language of emotions and an artform that emphasizes speaking out. These two qualities render performance
poetry a powerful medium for addressing HIV and AIDS stigma, a phenomenon that is embedded in the culture of silence.
A systematic review of applied theatre practice in the Indian context of mental health, resilience and wellbeing
Authors: Crossley Mark , Barrett Andy , Brown Brian J. , Coope Jonathan , Raghaven Raghu
Published: January 2020

Abstract This systematic review seeks to evaluate the documented uses of applied theatre practice within an Indian context. For the purposes of this review, specific applied theatre practices were focused upon, notably community theatre, theatre in education, theatre in health
education and Theatre for Development. This article was written in preparation for a collaborative research project (http://mhri-project.org) utilizing community theatre practices to investigate mental health and resilience within
slum (basti) communities in the city of Pune, in the state of Maharashtra in India. At its most particular level, the review focuses on theatre interventions within migrant slum communities. Of specific interest is the conjunction of applied theatre with research and practice in mental health
and wellbeing, and how such collaborations have investigated levels and modes of mental resilience within migrant communities. The review also draws upon related global research to contextualize and inform the Indian context. At present, systematic reviews are not prevalent within the research
fields of theatre generally or applied theatre specifically, yet these reviews arguably offer the breadth of objective evidence required to interrogate the efficacy of this practice. This review is therefore intended to rigorously map the existing academic research and the more diffuse online
dialogues within India that are pertinent to the subject; to consider the relations, contradictions, absences and inconsistencies within this literature; and, from this, to articulate key findings that may be integrated into the planning and delivery of new initiatives within this field.

In this study, the antioxidants and photosynthetic compounds of Verdolaga were examined. Compounds were extracted from distinctive segments of the verdolaga using various solvents such as methanol (40, 60, 80%), ethanol (40, 60, 80%), acetone (40, 60, 80%), and deionized water. The use of 80% methanol led to the highest extracted concentration of phenolic substances and flavonoids. The extracted products (Leaves, Stem strips, and Root strips) were evaluated for their radical scavenging capabilities with DPPH (IC50= 22.26, 20.56, and 32.10), and ABTS (IC50= 2.86, 3.70, and 5.24), reducing power (EC50= 15.70, 16.39, and 21.69), and peroxide scavenging activity (1C50= 1.717, 2.937, and 3.255), respectively. The extracted products were analyzed by a gas chromatography-mass spectrometer. Peroxidase, catalase, and polyphenol oxidase assays were completed for the crude extract of verdolaga’s leave, stem strips, and root strips. As indicated by these tests, extracts of the verdolaga’s roots, stems and leaves using 80% methanol yielded high antioxidant activity. The most elevated concentrations of extracted chlorophyll, lycopene, and carotenoids were from the leaves and the highest concentration of extracted tannin was noted from strips of stems. The highest measures of peroxidase and polyphenol oxidase were identified in root strips and the highest units of catalase was identified in leaves.

Published: January 2020

İsveç diğer Avrupa devletleriyle karşılaştırıldığında, ılımlı, hoşgörülü ve eşitlikçi mülteci politikalarını
uzun süre koruyan bir ülke olmuştur. İsveç’te mülteci politikaları 1980’lerin sonlarına kadar,
benzeri görülmemiş biçimde, farklı ideolojilere sahip siyasi partilerin işbirlikleriyle yürütülmüştür.
1990’ların başında çeşitli sebeplerle (Doğu-bloğu ülkelerinin çözülmesi, Balkanlarda yaşanan savaşlar,
ekonomik krizler, diktatör yönetimler gibi) ülkelerini terk eden kalabalıkların İsveç’i tercih etmesi,
mülteci politikalarında görece istikrarlı sürdürülen partiler arası işbirliğinin bozulmasına yol açmış
ve partiler arası fikir ayrılıklarını tetiklemiştir. 1990’ların sonu ve 2000’lerde sayıları belirgin biçimde
artan mültecilere ilişkin siyasi partiler arasında ortaya çıkan fikir ayrılıkları, 2015 yılında çoğunluğu
Suriye’deki iç savaştan kaçanların oluşturduğu rekor sayıda mülteci başvurusuyla krize dönüşmüştür.
Nitekim 2016 yılı OECD verilerine göre İsveç, diğer Avrupalı devletlere kıyasla nüfusuna göre en fazla
mülteci kabul eden devlet olmuş, bu durum ülke siyasetini alarma geçirmiştir. Bunun bir sonucu olarak
siyasi partilerin mülteci politikaları ve söylemlerinde belirgin bir ‘U’ dönüşü yaşanmıştır. Bu bağlamda

Decision trees in environmental justice research — a case study on the floods of 2001 and 2010 in Hungary
Authors: Nagy Gyula , Vida György , Boros Lajos , Ćirić Danijela
Published: January 2020

Environmental justice is a normative framework for the analysis of environmental impacts on the wellbeing of individuals and social groups. According to the framework, the deprived social groups and ethnic minorities are often more exposed to environmental risks and hazards due to their disadvantaged situation, and due to the lack of representation and political power. To manage the impacts of injustices and to include the citizen in the decision-making processes, proper information is needed on local attitudes and decision-making processes. Therefore, this study sought to (i) identify the main factors shaping the attitudes towards environmental injustices and (ii) to analyse the attitudes and perception of the various social groups and (iii) to identify the main factors which are shaping the attitudes and actions of those who were affected by the floods of 2001 and 2010 through the use of decision tree method. The data for the predictive model was acquired from a questionnaire survey conducted in two disadvantaged and flood-hit Hungarian regions. Based on the survey data, a principal component analysis (PCA) was conducted, which resulted in three principal components; fear, social change, and change in the built environment. The study focused only on the elements of the “fear principal component”, due to the decision tree tool homogenous groups identified in relation to this component. Our analysis showed that ethnicity has a determinative role in the emergence and the level of fear from floods; the Roma respondents expressed a significantly higher level of fear than others.

Published: January 2020

Learning in any context involves acquisition, storage and utilization of information by the human memory system. Teaching and learning in health professions is a complex process since it demands learners interact with a number of novel information and concepts and critically analyze them to make important clinical decisions. Therefore, it is imperative for Instructional designers and instructors in health professions education to optimize learning content by considering the characteristics of memory and learning processes of students. This review explores stages of the human memory system, the process of learning, the various types of cognitive loads a learner experiences while learning, and the implications of these factors on instructional designs on the basis of a fairly new theory in educational psychology – the Cognitive Load Theory (CLT). By analyzing the unique features of the processing, storage and retrieval of information by human memory system, this article advocates for health professional educators to plan and design instructional strategies that facilitate student learning.

Background: The knowledge and experience sharing of faculty and staff at universities and research institutes with their communities is a key element of success in achieving the organizational goals. Faculty members play a key role in universities. Accordingly, recognizing the importance of this capability in faculty members, this study aimed to investigate the status of knowledge and experience sharing based on the Ajzen model in faculty members at the ShahidBeheshti University of Medical Sciences in 2018. Methods: This descriptive-analytical study was conducted with 300 faculty members at the Shahid Beheshti University of Medical Sciences using stratified random sampling and simple random sampling. Data was gathered using a researcher created questionnaire and the analysis was conducted using SPSS 25 and LISREL 8.8. Results: The results showed that the significance level of a test for the relationship between knowledge and experience sharing components was less than α = 0.05, and there was a positive and significant correlation between knowledge and experience sharing components in faculty members at the Shahid Beheshti University of Medical Sciences. Most of the respondents’agreement regarding "knowledge and experience sharing" were related to behavioral control(mean=3.87; SD=0.353), behavior (mean=3.56; SD=0.328), attitude (mean=3.30; SD=0.344)subjective norm (mean=3.16; SD=0.435) and intention (mean=2.76; SD=0.284). Conclusion: This tool can be used by managers and university presidents to manage and translate knowledge in medical sciences universities.

Background: This study aimed to evaluate the effectiveness of debate as a learning tool for changing audiences’ views regarding the use of clinical guidelines in routine clinical practice. Methods: A debate scenario including different rationales for and against using guidelines in clinical practice, presented by the student section of Iranian Evidence Based Medicine Center of Excellence, was held at the first International Student Congress of Research Integrity and Evidence-Based Practice (Kish Island, Iran, December, 2015). The audience was first asked to check the papers given to them, and if they agreed to the terms, they were asked to choose,"Yes", "No", or "I don’t know". Results: Of the 400 individuals participating in the congress, 100 were present during the scheduled debate time. Among the 71 people completing pretest questionnaires, 73% (52)answered "yes" to the question, "Should we use guidelines? "About 7% (5) claimed that we shouldn’t use guidelines, and 20% (14) had no opinion about using them. Following the debate,the participants who chose "yes" to the guidelines remained in favor of their use in clinical practice. Of the 14 who did not have an opinion for guideline use, all agreed to use guidelines in clinical practice. Surprisingly, the five participants who were against guideline implementation remained fixed in their view, continuing to disagree regarding their use in clinical encounters. Conclusion: Although we were unable to change the attitudes of physicians who were against the use of guidelines in clinical practice, the debate caused a positive shift among participants who did not have an opinion regarding their use in clinical scenarios.

Seeds of eight lots of four tobacco varieties differing in vigour were studied. The initial germination percentage (GPUT) was 81-100% and the controlled greenhouse emergence percentage (CEP) was 55-91%. All seeds were treated by controlled deterioration (CD) at 20% moisture content
and 45°C for 24 hours, then some seeds were subjected to a standard germination test and the rest of the seeds were subjected to a conductivity test. The electrical conductivity (EC) of seed soak water was measured every six hours up to 54 hours. The results showed that relative conductivity
after CD (RCCD) was highly significantly correlated with GPCD after 30 to 48 hours soaking (r = -0.9324 to -0.9409, P < 0.001). After 36 and 42 hours, RCCD was significantly correlated (P < 0.01) with CEP (correlation coefficients
of -0.9120 and -0.9137, respectively). Therefore, it is suggested that measuring relative conductivity after CD could be used to rank tobacco seed lots for vigour. In addition, the best seed soaking time for EC measurement is 36 to 42 hours, with respect to both efficiency and accuracy.
Vyshnivetsky Castle Library of Prince Mychailo Servaty Vyshnivetsky – Historical Book Heritage and Object of Bibliological and Historical Reconstruction

Published: January 2020

The article has as its object the elucidation of the history of the Vyshnivetsky Castle Library, definition of the content of its fund, its historical and cultural significance, correlation of the founder of the Library Mychailo Servaty Vyshnivetsky with the Book.The Vyshnivetsky Castle Library was formed in the Ukrainian historical region of Volyn’, in the Vyshnivets town – “family nest” of the old Ukrainian noble family of the Vyshnivetskies under the “Korybut” coat of arm. The founder of the Library was Prince Mychailo Servaty Vyshnivetsky (1680–1744) – Grand Hetman and Grand Chancellor of the Grand Duchy of Lithuania, Vilno Voievoda. He was a politician, an erudite and great bibliophile. In the 30th–40th of the 18th century the main Prince’s residence Vyshnivets became an important centre of magnate’s culture in Rich Pospolyta. M. S. Vyshnivetsky’s contemporaries from the noble class and clergy knew quite well about his library and really appreciated it. According to historical documents 5 periods are defined in the Library’s history. In the historical sources the first place is occupied by old-printed books of Library collection and 7 Library manuscript catalogues dating from 1745 up to the 1835 which give information about quantity and topical structures of Library collection.The Library is a historical and cultural symbol of the Enlightenment epoch. The Enlightenment and those particular concepts and cultural images pertaining to that epoch had their effect on the formation of Library’s fund. Its main features are as follow: comprehensive nature of the stock, predominance of French eighteenth century editions, presence of academic books and editions on orientalistics as well as works of the ideologues of the Enlightenment and new kinds of literature, which generated as a result of this movement – encyclopaedias, encyclopaedian dictionaries, almanacs, etc. Besides the universal nature of its stock books on history, social and political thought, fiction were dominating.The reconstruction of the history of Vyshnivetsky’s Library, the historical analysis of the provenances in its editions give us better understanding of the personality of its owners and in some cases their philanthropic activities, and a better ability to identify the role of this Library in the culture life of society in a certain epoch.

OBJECTIVE:

To study the longitudinal associations of 12th-grade binge drinking with driving while impaired (DWI), riding with an impaired driver (RWI), blackouts, extreme binge drinking, and risky driving (self-reported Checkpoints Risky Driving Scale) among emerging adults up to 4 years after leaving high school.

METHODS:

The data were all 7 waves (W 1 to W 7 of the NEXT Generation Health Study; a US nationally representative study (N = 2785) with a probability cohort of 10th-graders (mean age = 16.2 years; SE = 0.03) starting in the 2009–2010 year. Binary and ordinal logistic regressions were used for the analysis.

RESULTS:

Binge drinking prevalence in W1 to W3 was 27.2%, 23.8%, and 26.8%, respectively. Twelfth-grade binge drinking was associated with a higher likelihood of DWI, RWI, blackouts, and risky driving in W4 to W7 and extreme binge drinking in W7. Adolescents who binged ≥3 times in high school were more likely to DWI, RWI, blackout (W4 to W7), be involved in extreme binge drinking (W7), and report riskier driving several years after high school. In some waves, parental practices appeared to have enduring effects in protecting against DWI, RWI, and blackouts.

CONCLUSIONS:

Twelfth-grade binge drinking is a robust predictor of early adulthood DWI, RWI, blackout, extreme binge drinking, and risky driving. Our study suggests that ongoing parental practices could be protective against DWI, RWI, and blackouts once adolescents transition from high school into early adulthood. Prevention programs that incorporate binge drinking–focused screening and bolster parental practices may reduce the likelihood of later major alcohol-related health-risk behaviors and consequences in emerging adults.
Evaluating the Analytic - Continental Divide: Impact on Education in Croatia
Authors: Novak Ivona
Published: January 2020

Contemporary Western philosophy has been generally perceived as one that encompasses two divergent traditions of philosophical thought: analytic and continental. A number of writers have drawn attention to the difficulty of explaining the differences between them. A small number of authors have even questioned the credibility of the analytic-continental division. In this paper I argue that the gulf between traditions is real and has a negative impact on three elements of education in Croatia: philosophy as an academic subject, students and university professors. Before delving into the aforementioned issue, I briefly specify areas of philosophical inquiry where the gulf is the most evident. I end paper with several suppositions concerning the future path of both traditions, which are mostly based on the idea of cooperation between analytic and continental philosophers as it would profoundly contribute to the advancement of teaching philosophy.
