Evaluating Wellness Interventions for Resident Physicians: A Systematic Review
Authors: Eskander Jessica , Rajaguru Praveen P. , Greenberg Paul B.
Published: January 2021

Background

Wellness initiatives implemented by graduate medical education programs can help mitigate burnout in resident physicians.

Objective

This systematic review seeks to identify factors that impact the effectiveness of resident wellness interventions and to provide a conceptual framework to guide future interventions.

Methods

Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, 6 electronic databases were searched in November 2019 using variations of the keywords “resident physicians,” “wellness,” and “intervention.” Peer-reviewed full-text English-language articles on controlled studies were considered for inclusion. The quality of the studies was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) guidelines.

Results

The initial search disclosed 1196 articles, of which 18 studies enrolling 666 resident physicians met inclusion criteria for qualitative review. Interventions using peer support and individual meditation enhanced well-being. Effective wellness interventions also used educational theory to guide program development, surveyed participants to guide intervention design, incorporated programming into existing didactic curricula, and recruited voluntary participants. The quality of most of the included studies was poor (13 of 18, 72%) and could be improved by using standardized wellness assessments supported by validity evidence.

Conclusions

This systematic review suggests that future resident wellness initiatives should focus on grounding interventions in educational theory, forging consensus on wellness instruments with validity evidence, and examining the impact of initiatives on patient outcomes. A logic model can provide a framework for designing and implementing effective wellness interventions.

Authors: Scicchitano Emily , Stark Phillip , Koetter Paige , Michalak Nathan , Zurca Adrian D.
Published: January 2021

Background

Closed-loop communication (CLC) is associated with decreased medical errors and improved time-to-task completion during resuscitations. Depriving team leaders of sight during training may accelerate the acquisition of favorable communication skills; however, its effect on the frequency of CLC is unclear, especially with trainees.

Objective

We assessed the effect of depriving interns of sight during advanced cardiovascular life support (ACLS) on verbal communication patterns and resuscitation confidence.

Methods

All interns undergoing ACLS training in June 2019 at a single center were eligible. Interns were randomized to blindfolded training (BT) or standard training (ST). BT team leaders were blindfolded during practice sessions and permitted to use sight during testing. Testing scenarios were video- and audio-recorded. Recordings were assessed for teams' performance and communication patterns. Participants were surveyed for confidence with resuscitation skills before and after ACLS training.

Results

All 87 eligible interns participated in the study (100% participation). Eighty-five of 87 (98%) interns were included for analysis; 46 were randomized to BT and 39 to ST. Interns in the BT group were significantly more likely to exhibit CLC (mean: BT 20.3, ST 16.6; P = .003), directed communication (mean: BT 4.3, ST 1.5; P < .001), and follower-initiated communication (mean: BT 12.8, ST 10.2; P = .028). There was no significant difference in clinical performance measures or self-reported confidence with resuscitation between BT and ST groups.

Conclusions

Blindfolding trainees results in greater instances of CLC, directed communication, and follower-initiated communication during ACLS training.

Objektif. Proses pemodelan karakter 3D memegang peranan penting dalam menghasilkan model karakter 3D yang baik. Proses ini merupakan proses awal yang harus dilalui oleh seorang desainer dalam membuat sebuah model karakter 3D. Setelah proses pemodelan dikerjakan dengan baik agar karakter tersebut bisa dibuat bergerak maka diperlukan proses rigging. Dengan proses pemodelan dan rigging tersebut model karakter 3D bisa digunakan untuk menghasilkan animasi sesuai dengan keinginan animator. Tentunya seorang animator akan memerlukan kerja keras untuk membuat suatu adegan gerakan apabila animasi yang dibuat masih manual. Untuk itu dengan memanfaatkan data BVH, animator akan lebih ringan dalam membuat adegan animasinya. Hasil animasi karakter di tunjukkan kepada 40 responden untuk menilai dan menghasilkan rata-rata tingkat humanoid animasi karakter bernilai 65%.

Material and Metode. Menganimasikan model karakter 3D memanfaatkan hasil motion capture (.bvh)

Hasil. Animasi karakter 3D dengan menggunakan hasil motion capture menghasilkan animasi yang humanoid.

Kesimpulan. Hasil motion capture merupakan susunan tulang yang sudah dilengkapi dengan hasil perekaman gerakan sehingga untuk memproduksi animasi model karakter 3D akan lebih mudah karena animator tidak perlu menggambar tiap gerakan yang diinginkan.

Abstrack

Objective. The process of modeling 3D characters plays an important role in producing good 3D character models. This process is the initial process that must be passed by a designer in creating a 3D character model. After the modeling process is done well so that the character can be moved, a rigging process is needed. With the modeling and rigging process, 3D character models can be used to produce animations in accordance with the wishes of the animator. Of course, an animator will need to work hard to create a motion scene if the animation created is still manual. For this reason, by utilizing BVH data, animators will be lighter in making their animated scenes. The results of the character animation were shown to 40 respondents to rate and produce an average humanoid character animation level of 65%.  

Materials and Methods. Menganimasikan model karakter 3D memanfaatkan hasil motion capture (.bvh)

Results. 3D character animation using the results of motion capture produces humanoid animation.

Conclusion. The result of motion capture is the arrangement of bones that has been equipped with the results of recording the motion so that to produce animated 3D character models will be easier because the animator does not need to draw every desired movement.

Authors: MT Bolori , SB Mustapha , B Jidda
Published: January 2021

The study assessed health hazards associated with agrochemicals usage among vegetable farmers in Maiduguri and its Environs, Nigeria. Multi - stage sampling techniques was employed to select 160 vegetable farmers for this study. Both descriptive (frequency distribution and percentages) and inferential (logit regression) statistics were used to analyze the data. The study revealed that majority (59.37%) of the respondents were members of vegetable farmers’ organization and half (50.00%) of them were visited by extension agents less than thrice with majority (85.00%) of them had no access to credit during the period under study. The study revealed the most common symptoms of health hazards associated with agro-chemicals usage among respondents were skin problems (67.70%), dizziness (57.50%) and headache (52.50) in the study area. The logit regression revealed that extension contact had a positively significant influence at p < 0.05 level, while access to credit, sources of credit, availability of agro-chemicals shop and membership of FBOs had significant influence at p < 0.10 level each on wearing of PPEs during agro-chemicals application. The most important constraint affecting PPEs use was high cost of PPEs as reported by 55.00% of the respondents. The study recommended that vegetable farmers in the study area should be encouraged to form strong farmer organisations that will enable them to work as a team in order to eradicate or minimize the constraints of high cost of PPEs by obtaining subsidized PPEs from government for improved use of the same.

Authors: KÖPRÜ Ferhat , AYAS Bahadır
Published: January 2021

In this study, the criterion validity of the Anadolu-Sak Intelligence Scale (ASIS) was examined within the scope of the identification system of Education Programs for Talented Students (EPTS). The research participant consisted of 153 students. 30 of them were mathematically and scientifically gifted and 123 were non-gifted by the EPTS identification system. Intelligence scores were obtained by ASIS and talent and creativity scores were obtained by Math Ability Test (MAT) and Creative Scientific Ability Test (CSAT). Findings of the study showed that gifted group’s ASIS scores were significantly higher than the non-gifted group’s scores. Participants were divided into three groups (upper 27% middle 46% lower 27%) according EPTS scores and significant differences were found between the average intelligence scores of these three groups [(F(2.128) = 49.361, p< .001; Ƞ2 = 0.435]. To examine the predictive validity of the ASIS, binary logistic regression analysis was conducted and the model correctly classified 84.3% of the participants as gifted and non-gifted. For the ASIS’s concurrent validity significant correlation coefficients were found between the ASIS scores and EPTS, MAT and CSAT scores (rEPTS = .77; rMAT = .72; rCSAT = .55; p <.001). As a result of research findings it can be concluded that ASIS has satisfying criterion validity.

The mobile user would be able to use any application that requires an e-signature is called as Mobile Signature (m-signature). Msignature can be created by different ways, such as Server-based signatures, Mobile Signature Service (MSS), Mobile Signature Application Unit (MSAU). But those have several limitations. In this work, we present the implementation of mobile payment system using m- signature service to an insurance company and for a mobile shop.
AUTHENTICATION OF DIGITAL DOCUMENTS USING SECRET KEY BIOMETRIC WATERMARKING
Authors: ANITHA V. , VELUSAMY R.LEELA
Published: January 2021

Digital documents play a major role in modern era. They are easy to generate, modify and manage. The easy modifiable property of digital document makes it more vulnerable to forgery. It can be easily tampered or forged. So the challenge is to produce digital documents that are highly resistant to forgery and reliably confirms the real owner of the document. This can be resolved by biometric watermarking which make a direct relation between the document and its owner. A new biometric watermarking technique with secret key is proposed to digitize the authoritative documents issued by government / other organizations as a part of UID / Aadhar card project of India using biometric watermarking. Biometric code is generated from the biometric data collected from the owner of the document. The biometric code is watermarked in the document with a secret key to generate a biometric watermarked document that authenticates the real owner. Dewatermarking the document with the same key yields the biometric code that can be used for authentication of the document. If the document is tampered in any way it will be indicated in the extracted watermark. Experimental results show that 100% accuracy is obtained in authenticating the genuine documents.
HYBRID CHANNEL ALLOCATION IN WIRELESS CELLULAR NETWORKS
Authors: PANCHOLI SHRUTI , SHUKLA PANKAJ
Published: January 2021

The enormous growth of mobile telephone traffic, along with the limited number of channels available, requires efficient reuse of channels. Channel allocation schemes can be divided into three categories: Fixed Channel Allocation (FCA), Dynamic Channel Allocation (DCA) and Hybrid Channel Allocation (HCA). In HCA, channels are divided into two disjoint sets: one set of channels is assigned to each cell on FCA basis, while the others are kept in a central pool for dynamic assignment. This paper presents a hybrid channel allocation notification to the central pool on each channel request that cannot be satisfied locally at the base station. This notification will request more than one channel to be assigned to the requesting cell. When FCA would not support call then borrowed channels will be in use. The simulation study of the protocol indicates that the blocking probability of HCA will be low for less traffic and high for high traffic.

Authors: VOHRA RASHI , PATEL BRAJESH
Published: January 2021

The utmost negative impact of advancement of technology is an exponential increase in security threats, due to which tremendous demand for effective electronic security is increasing importantly. The principles of any security mechanism are confidentiality, authentication, integrity, non-repudiation, access control and availability. Cryptography is an essential aspect for secure communications. Many chaotic cryptosystem has been developed, as a result of the interesting relationship between the two field chaos and cryptography phenomenological behavior. In this paper, an overview of cryptography, optimization algorithm and chaos theory is provided and a novel approach for encryption and decryption based on chaos and optimization algorithms is discussed. In this article, the basic idea is to encrypt and decrypt the information using the concept of genetic algorithm with the pseudorandom sequence further used as a key in genetic algorithm operation for encryption: which is generated by application of chaotic map. This attempt result in good desirable cryptographic properties as a change in key will produce undesired result in receiver side. The suggested approach complements standard, algorithmic procedures, providing security solutions with novel features.
LANGUAGE INDEPENDENT ROBUST SKEW DETECTION AND CORRECTION TECHNIQUE FOR DOCUMENT IMAGES
Authors: N Neha.
Published: January 2021

Document image processing is an increasingly important technology essential in all optical character recognition (OCR) systems and for automation of various office documents. A document originally has zero-skew (tilt), but when a page is scanned or photo copied, skew may be introduced due to various factors and is practically unavoidable. Presence even a small amount of skew (0.50) will have detrimental effects on document analysis as it has a direct effect on the reliability and efficiency of segmentation, recognition and feature extraction stages. Therefore removal of skew is of paramount importance in the field of document analysis and OCR and is the first step to be accomplished. This paper presents a novel technique for skew detection and correction which is both language and content independent. The proposed technique is based on the maximum density of the foreground pixels and their orientation in the document image. Unlike other conventional algorithms which work only for machine printed textual documents scripted in English, this technique works well for all kinds of document images (machine printed, hand written, complex, noisy and simple). The technique presented here is tested with 150 different document image samples and is found to provide results with an accuracy of 0.10

Published: January 2021

Iris recognition is an automated method of biometric identification that uses mathematical pattern-recognition techniques on video images of the irises of an individual’s eyes, whose complex random patterns are unique and can be seen from some distance. Modern iris recognition algorithms can be computationally intensive, yet are designed for traditional sequential processing elements, such as a personal computer. However, a parallel processing alternative using Field Programmable Gate Array offers an opportunity to speed up iris recognition. Within the means of this project, iris template generation with directional filtering, which is a computationally expensive, yet parallel portion of a modern iris recognition algorithm, is parallelized on an FPGA system. An algorithm that is both accurate and fast in a hardware design that is small and transportable are crucial to the implementation of this tool. As part of an ongoing effort to meet these criteria, this method improves a iris recognition algorithm, namely pupil isolation. A significant speed-up of pupil isolation by implementing this portion of the algorithm on a Field Programmable Gate Array.

Published: January 2021

Clinical investigation of some sleep disorders, stress testing, ambulatory monitoring requires simultaneous monitoring of heart rate and respiratory rates. [3] Numerous methods have been reported for deriving respiratory information from the electrocardiogram (ECG). [1] Initially ECG signal is sent to microcontroller AT89S52 through ADC0848. The digital samples are once again transmitted to personal computer via a cable. The digital data is read with the help of graphical user interface software – Visual C++ (serial port programming). The data is stored in an array and the QRS peaks per minute are detected & heart rate is calculated. As these QRS peaks consist of respiratory information, an algorithm will be applied onto the QRS data to find the number of slopes per minute, which gives the respiratory rate. Hence the Heart Rate & Respiratory Rate per minute will be calculated and displayed real time on PC.

Cotidiano escolar e justificação científica do fazer pedagógico: contradições, distanciamentos e perspectivas de luta no campo da formação humana
Authors: Silva Jeferson Luis da , Ratto Cleber Gibbon , Link Elmer Erico
Published: January 2021

Neste trabalho, buscamos refletir sobre uma possível contradição entre a alta produção de conhecimento das ciências humanas em educação e a constatação de uma crescente perda da qualidade da educação básica no país. Questionamos a possibilidade de um possível distanciamento da prática educativa em relação ao projeto de humanização e civilizatório próximo da noção de paideia, em especial, pela imposição de demandas econômicas e ausência de oportunidades de autorrealização social, com baixa redistribuição de recursos, gerando ressentimentos numa significativa parcela da sociedade. Por fim, sinalizamos para uma necessidade da retomada do exercício de valorização das lutas por  reconhecimento ético, da valorização qualitativa das relações sociais, bem como, da prática focada na emancipação dos sujeitos enquanto fundamento das ciências da educação e da própria escola. Para produção desta reflexão, adotamos o caminho do ensaio teórico dada sua natureza interpretativa e reflexiva.

Material and methods

This study included 178 pregnant women with sonographically detected SCH in the 1st trimester, and 350 pregnant controls without SCH. Data on maternal age, smoking status, gestational week at diagnosis, location of SCH, medications before diagnosis, gestational week at delivery, delivery route and pregnancy outcomes (first trimester vaginal bleeding, pre-eclampsia, gestational diabetes, intrauterine growth restriction (IUGR), placental abruption, preterm delivery < 37 weeks, early pregnancy loss and intrauterine death) were retrieved retrospectively from hospital records. Pregnant women with SCH were divided into 3 groups according to the size of hematoma including small SCH (SCH-I group, n = 47), medium- size SCH (SCH-II group, n = 110) and large SCH (SCH-III group, n = 21) groups.

Results

Subchorionic hematoma was associated with significantly lower gestational age at delivery (p < 0.001) and higher rate of first trimester bleeding (p < 0.001) compared with the control group, regardless of the size of the hematoma. Placental abruption (p = 0.002) and early pregnancy loss (p < 0.001) were significantly more common in SCH-II and -III groups than in the control group. SCH-III group was associated with a significantly higher rate of < 37 gestational weeks at delivery (p < 0.001), first trimester vaginal bleeding (p < 0.001), early pregnancy loss (p < 0.001), IUGR (p = 0.003) and preterm delivery (p < 0.001) compared to both lesser size hematoma and control groups.

Conclusions

In conclusion, our findings suggest that large SCH might indicate an increased risk of adverse pregnancy outcomes such as 1st trimester vaginal bleeding, early pregnancy loss, IUGR, placental abruption or preterm delivery. These findings are important to guide the patients with SCH for detailed clinical evaluation.
The impact of selected food additives on the gastrointestinal tract in the example of nonspecific inflammatory bowel diseases
Authors: Jarmakiewicz - Czaja Sara , Piątek Dominika , Filip Rafał
Published: January 2021

Various types of food additives are widely used in the food industry. Due to their properties extending the usefulness for consuming food products, they give them different colours, consistency, or taste. The products are marked ‘E’ and the code is assigned to the subscription used. Many of the supplements affect human health negatively. Emulsifiers or stabilizers can lead to epithelial loads and the development of inflammation. Sucrose and other sweeteners may change the composition of the intestinal microflora and thus lead to intestinal blockage. Some additives classified as preservatives are available and may predispose to intestinal dysbiosis. Available substances belonging to food dyes may predispose to genotoxic and cytotoxic effects and cause inflammation in the intestines. Substances added to food can also cause disorders of intestinal homeostasis.

Представлены результаты численного моделирования взаимодействия аккреционных дисков при прохождении периастра в двойной звезде типа Т Тельца с эллиптичной орбитой. Рассмотрена структура системы ударных волн в аккреционных дисках и между ними и ее изменение с течением времени. Обсуждается возможность построения аналитической модели взаимодействия аккреционных дисков.

We present the results of numerical simulation of interacting accretion disks in a T Tauri type binary with elliptic orbit. Using these results we study structure and evolution of the system of shock waves in accretion disks and between them. Finally we discuss the possibility of bringing up an analytical model for accretion disk interaction.
Observational signs of wide binary stars dissolution in Gaia DR2 data

По данным Gaia DR2 в радиусе 100 пк от Солнца исследованы двойные звезды с общим собственным движением до расстояния между компонентами 3 пк. Для исключения возможных случайных совпадений смоделирована искусственная выборка случайных пар. Показано, что принятый способ отбора пар с общим собственным движением делает загрязнение выборки случайными совпадениями незначительным даже при больших расстояниях между компонентами; величина такого загрязнения оценена численно. Получено бимодальное распределение по логарифму расстояния между компонентами, демонстрирующее для очень широких пар минимум, связанный с распадом систем, на расстоянии ≈ 0.5 пк, и дальнейший рост, формируемый распавшимися, медленно расходящимися компонентами.

Binary and common proper motion stars within 100 pc of the Sun are being investigated using Gaia DR2 data. An artificial random pairs sample is constructed to exclude possible random pairing contamination. Numerical estimation of this contamination shows that the chosen method to select the common proper motion stars yields little contamination even at high separations. In a logarithmic scale the separation distribution appear to have a minimum at ≈ 0.5 pc, most likely related to binary star dissolution, with further increase formed by dissolved, slowly distancing components.

Сообщается о завершении очередного этапа работ по созданию эшелле-спектрографа ESPriF, предназначенного для спектроскопии и спектрополяриметрии звезд и планетарных туманностей. Потенциальное качество нового спектрографа оценивается относительно характеристик Основного звездного спектрографа (ОЗСП) БТА, используемого сегодня для обеспечения большей части программ спектроскопии и спектрополяриметрии звезд в РФ. Спектрограф ESPriF планируется использовать в качестве одного из средств наземной поддержки проекта «Спектр-УФ».

In this paper we inform that the next step of a creation of echellé spectropolarimeter ESPriF for the primary focus of the 6-m BTA telescope has finished. The instrument will be used for spectroscopy and spectropolarimetry of stars and planetary nebulae. The instrument potential quality was estimated in comparison with the Main Stellar Spectrograph (MSS) of BTA, which is used currently for the most Russian spectroscopic and spectropolarimetric programs. The ESPriF spectrograph will be used as an instrument for ground support observations of the “Spektr-Uf” space mission.
Reflexivity and the Symbolic We-Relation
Authors: Gattamorta Lorenza
Published: January 2021

This essay considers the features constituting the symbolic We-relation to seek how the reflexive Self can generate changes to the Self, the You, and the We-relation itself. While critically dialoguing with phenomenological and pragmatist social theories, the essay investigates how subjectivity emerges in the interaction with (verbal and non-verbal) symbols and tries to avoid both subjectivism and the relationism.
