Few-Shot Rolling Bearing Fault Diagnosis with Metric-Based Meta Learning
Authors: Wang Sihan , Wang Dazhi , Kong Deshan , Wang Jiaxing , Li Wenhui , Zhou Shuai
Published: November 2020

Fault diagnosis methods based on deep learning and big data have achieved good results on rotating machinery. However, the conventional deep learning method of bearing fault diagnosis is mostly based on laboratory artificial simulation data, and there is an error with actual fault data, which will reduce the generalization performance of the deep learning method. In addition, labeled data are very precious in real industrial environment. Due to expensive equipment and personnel safety issues, it is difficult to obtain a large amount of high-quality fault labeling data. Therefore, in this paper, we propose a metric-based meta-learning method named Reinforce Relation Network (RRN) for diagnosing bearing faults with few-shot samples. In the proposed method, a 1D convolution neural network is used to extract fault features, and a metric learner is used to predict the similarity between samples under different transfer conditions. Label smoothing and the Adabound algorithm are utilized to further improve the performance of network classification. The performance of the proposed method is verified on a dataset which contains artificial damage and natural damage data. The comparison studies with other methods demonstrate the superiority of the proposed method in the few-shot scenario.
Intelligent Calibration of Static FEA Computations Based on Terrestrial Laser Scanning Reference
Authors: Xu Wei , Bao Xiangyu , Chen Genglin , Neumann Ingo
Published: November 2020

The demand for efficient and accurate finite element analysis (FEA) is becoming more prevalent with the increase in advanced calibration technologies and sensor-based monitoring methods. The current research explores a deep learning-based methodology to calibrate FEA results. The utilization of monitoring reference results from measurements, e.g., terrestrial laser scanning, can help to capture the actual features in the static loading process. We learn the deviation sequence results between the standard FEA computations with the simplified geometry and refined reference values by the long short-term memory method. The complex changing principles in different deviations are trained and captured effectively in the training process of deep learning. Hence, we generate the FEA sequence results corresponding to next adjacent loading steps. The final FEA computations are calibrated by the threshold control. The calibration reduces the mean square errors of the FEA future sequence results significantly. This strengthens the calibration depth. Consequently, the calibration of FEA computations with deep learning can play a helpful role in the prediction and monitoring problems regarding the future structural behaviors.

Published: November 2020

The environmental challenges the world faces nowadays have never been greater or more complex. Global areas covered by forests and urban woodlands are threatened by natural disasters that have increased dramatically during the last decades, in terms of both frequency and magnitude. Large-scale forest fires are one of the most harmful natural hazards affecting climate change and life around the world. Thus, to minimize their impacts on people and nature, the adoption of well-planned and closely coordinated effective prevention, early warning, and response approaches are necessary. This paper presents an overview of the optical remote sensing technologies used in early fire warning systems and provides an extensive survey on both flame and smoke detection algorithms employed by each technology. Three types of systems are identified, namely terrestrial, airborne, and spaceborne-based systems, while various models aiming to detect fire occurrences with high accuracy in challenging environments are studied. Finally, the strengths and weaknesses of fire detection systems based on optical remote sensing are discussed aiming to contribute to future research projects for the development of early warning fire systems.
An sEMG-Controlled 3D Game for Rehabilitation Therapies: Real-Time Time Hand Gesture Recognition Using Deep Learning Techniques
Authors: Nasri Nadia , Orts-Escolano Sergio , Cazorla Miguel
Published: November 2020

In recent years the advances in Artificial Intelligence (AI) have been seen to play an important role in human well-being, in particular enabling novel forms of human-computer interaction for people with a disability. In this paper, we propose a sEMG-controlled 3D game that leverages a deep learning-based architecture for real-time gesture recognition. The 3D game experience developed in the study is focused on rehabilitation exercises, allowing individuals with certain disabilities to use low-cost sEMG sensors to control the game experience. For this purpose, we acquired a novel dataset of seven gestures using the Myo armband device, which we utilized to train the proposed deep learning model. The signals captured were used as an input of a Conv-GRU architecture to classify the gestures. Further, we ran a live system with the participation of different individuals and analyzed the neural network’s classification for hand gestures. Finally, we also evaluated our system, testing it for 20 rounds with new participants and analyzed its results in a user study.
First-Order Linear Mechatronics Model for Closed-Loop MEMS Disk Resonator Gyroscope
Authors: Wang Hao , Wang Xiupu , Xie Jianbing
Published: November 2020

In this paper, a first-order closed-loop mechatronics model of a micro-electromechanical system (MEMS) disk resonator gyroscope (DRG) with a configurable ASIC is established for closed-loop design and performance analysis. There are usually some nonlinear modules in the gyroscope mechatronics model, and it is difficult to design the closed-loop controllers using classical automatic control theory. An order-reduction method (ORM) based on the Laplace transform and inverse Laplace transform is proposed to linearize the nonlinear modules. The linearized model is proved to show good agreement with the original mechatronics model in terms of system response. The experimental verification was conducted to demonstrate the validation of this method.
Blockchain Reference System Architecture Description for the ISA95 Compliant Traditional and Smart Manufacturing Systems
Authors: Yalcinkaya Erkan , Maffei Antonio , Onori Mauro
Published: November 2020

The next-generation technologies enabled by the industry 4.0 revolution put immense pressure on traditional ISA95 compliant manufacturing systems to evolve into smart manufacturing systems. Unfortunately, the transformation of old to new manufacturing technologies is a slow process. Therefore, the manufacturing industry is currently in a situation that the legacy and modern manufacturing systems share the same factory environment. This heterogeneous ecosystem leads to challenges in systems scalability, interoperability, information security, and data quality domains. Our former research effort concluded that blockchain technology has promising features to address these challenges. Moreover, our systematic assessment revealed that most of the ISA95 enterprise functions are suitable for applying blockchain technology. However, no blockchain reference architecture explicitly focuses on the ISA95 compliant traditional and smart manufacturing systems available in the literature. This research aims to fill the gap by first methodically specifying the design requirements and then meticulously elaborating on how the reference architecture components fulfill the design requirements.

Authors: Adeluyi Olufemi , Risco-Castillo Miguel A. , Liz Crespo María , Cicuttin Andres , Lee Jeong-A
Published: November 2020

Personalized health monitoring of neural signals usually results in a very large dataset, the processing and transmission of which require considerable energy, storage, and processing time. We present bioinspired electroceptive compressive sensing (BeCoS) as an approach for minimizing these penalties. It is a lightweight and reliable approach for the compression and transmission of neural signals inspired by active electroceptive sensing used by weakly electric fish. It uses a signature signal and a sensed pseudo-sparse differential signal to transmit and reconstruct the signals remotely. We have used EEG datasets to compare BeCoS with the block sparse Bayesian learning-bound optimization (BSBL-BO) technique—A popular compressive sensing technique used for low-energy wireless telemonitoring of EEG signals. We achieved average coherence, latency, compression ratio, and estimated per-epoch power values that were 35.38%, 62.85%, 53.26%, and 13 mW better than BSBL-BO, respectively, while structural similarity was only 6.295% worse. However, the original and reconstructed signals remain visually similar. BeCoS senses the signals as a derivative of a predefined signature signal resulting in a pseudo-sparse signal that significantly improves the efficiency of the monitoring process. The results show that BeCoS is a promising approach for the health monitoring of neural signals.

Published: November 2020

The increasing recognition of minimally invasive thermal treatment of tumors motivate the development of accurate thermometry approaches for guaranteeing the therapeutic efficacy and safety. Magnetic Resonance Thermometry Imaging (MRTI) is nowadays considered the gold-standard in thermometry for tumor thermal therapy, and assessment of its performances is required for clinical applications. This study evaluates the accuracy of fast MRTI on a synthetic phantom, using dense ultra-short Fiber Bragg Grating (FBG) array, as a reference. Fast MRTI is achieved with a multi-slice gradient-echo echo-planar imaging (GRE-EPI) sequence, allowing monitoring the temperature increase induced with a 980 nm laser source. The temperature distributions measured with 1 mm-spatial resolution with both FBGs and MRTI were compared. The root mean squared error (RMSE) value obtained by comparing temperature profiles showed a maximum error of 1.2 °C. The Bland-Altman analysis revealed a mean of difference of 0.1 °C and limits of agreement 1.5/−1.3 °C. FBG sensors allowed to extensively assess the performances of the GRE-EPI sequence, in addition to the information on the MRTI precision estimated by considering the signal-to-noise ratio of the images (0.4 °C). Overall, the results obtained for the GRE-EPI fully satisfy the accuracy (~2 °C) required for proper temperature monitoring during thermal therapies.

MICROETHNONYMS IN SOUTH PSKOV DIALECTS: BULBASHI, MOSKALI, SKOBARI AND POLYAKI
Authors: Ryko A.I.
Published: November 2020

The article analyzes microethnonyms - collective group names “bulbashi”, “moskali”, “skobari” and “poliaki” used in the Nevelsky district of the Pskov region. From the explanations of the dialect speakers, it follows that the word “bulbashi” is familiar rather from the outside - this is how speakers of other dialects often call them themselves. The word “skobari” is almost unknown in the usual meaning of ‘resident of Pskov or Pskov region', but it was used in relation to newcomers - the old believers. The ethnonym “moskali” is also used in the same meaning. It was recorded in a similar meaning in neighboring dialects, where the word “poliaki” was also used to designate the old believers. Thus, in places of South- Western migration of the old believers, local residents called them “moskali”, “skobari” or “poliaki”; the first ethnonym had a more general meaning, and “skobari” and “poliaki” are self-names of the old believers, depending on their initial settlement in the Pskov region.

Katav-Ivanovsk earthquake on 04.09.2018, mb=5.4 (Urals)
Authors: Dyagilev Ruslan , Verkholantsev Filipp , Varlashova Yuliya , Shulakov Denis , Gabsatarova Irina , Epifanskiy Aleksey
Published: November 2020

The article summarizes the instrumental and macroseismic data obtained in the area of Katav-Ivanovsk earthquake, which occurred on September 4, 2018, in Chelyabinsk region, Russia. The earthquake was the strongest instrumentally recorded earthquake in the Urals (mb=5.4) and at the same time, it had the most seismic intensity among other earthquakes in Russia in 2018 (I0=6 points). The uniqueness of this event was given by the fact that after it for the first time for the Urals the aftershock process was recorded, the active stage of which lasted more than 1 year. Like the mainshock, some aftershocks had a significant macroseismic effect. The work contains the results of studies that allowed to determine the exact
coordinates of the epicenter in conditions of lack of near stations using the relative location technique. New processing approaches also made it possible to estimate the depth of the focus through a function of phase spectrum matching. Finally, a considerable amount of macroseismic data formed the basis of the macroseismic field map.

Even if the alarm caused by coronavirus in Italy has actually arisen as a medical emergency, it soon became apparent that there would be may other spill-over effects. The education system has been one of the first areas which have been adversely affected by this pandemic, as schools and university have been closed since the very first weeks. Schools have thus begun to build new ways of schooling in order to keep in contact with students and families and to go on with teaching activities. This article aims to focus on students’, parents’ and teachers’ educational experience in the time of the Covid-19 emergency. After a brief study of the situation of the Italian school before this pandemic, the paper seeks to investigate the lockdown effect on the school-family relationships and on the way of schooling during this emergency time. Findings show that distant learning has caused tensions and difficulties among teachers, students and parents, but at the same time it has enabled to reflect and to build new unexpected ways of drawing connections, guaranteeing socializing and refiguring the school on its role both of transmitting knowledge and of training the future citizen
¿Por qué desde la didáctica no se favorece la formación del profesorado?
Authors: De la Herrán Gascón Agustín , Fortunato Iván
Published: November 2020

Este ensayo también podría haberse titulado: “¿Y si la formación del profesorado estuviese desorientada radicalmente?”. Se inscribe en otra pregunta, más amplia: “¿Y si nuestra educación y la Pedagogía estuviesen radicalmente equivocadas?”. En su contenido se exponen argumentos con el objetivo de expresar posibles insuficiencias de la formación del profesorado y, por tanto, de la Didáctica, como ciencia de la formación por antonomasia. Se presenta la posibilidad de que en educación y formación predomine un sesgo general hacia lo externo y, consecuentemente, un déficit de atención radical, deduciéndose el imperativo de reenfocar completamente la formación del profesorado. En las siguientes líneas se condensan más de dos décadas de observaciones en este sentido. Desde una perspectiva metodológica, se procederá con una orientación dialéctica y hermenéutica, apoyada en el “enfoque radical e inclusivo de la formación”, desde el que se ofrecerán argumentos críticos con una finalidad constructiva. Tras responder al objetivo, el trabajo ofrece un modelo de formación alternativo, que aporta novedad al conocimiento pedagógico en una temática relevante para investigadores y profesionales de la enseñanza.

Authors: Putranto W. A. , Khaeruman Khaeruman , Susanto Susanto
Published: November 2020

Pada industri kimia, desalinasi dan minyak banyak sekali terjadi pembentukan kerak kalsium karbonat di dalam pipa yang berakibat pada penyempitan diameter dalam pipa dan pengurangan kinerja perpindahan panas. Makalah ini memaparkan proses kristalisasi CaCO3 di dalam pipa dengan aliran laminer. Percobaan ini dilakukan dengan mencampurkan dua larutan ekuimolar CaCl2 dan Na2CO3 dengan konsentrasi Ca2+ 3.000 ppm. Parameter yang diteliti adalah laju alir larutan 50 ml/menit), suhu (27 oC, 35 oC, 50 oC) dan penambahan aditif asam tartarat (0,00; 1,00; 10,00 ppm) sebagai penghambat proses pengerakan. Proses pembentukan kerak CaCO3 dipantau dengan mengukur perubahan konduktivitas larutan yang bertujuan untuk mengetahui waktu induksi sebagai pertanda awal terbentuknya kerak CaCO3. Waktu induksi yang diperoleh adalah bervariasi dari 20 menit hingga 38 menit. Laju aliran dengan suhu yang tinggi menghasilkan banyak endapan kerak CaCO3. Parameter suhu dapat meningkatkan kristalisasi CaCO3. Kerak yang diperoleh dari percobaan dikeringkan dan ditimbang untuk diperoleh massa kerak kemudian dikarakterisasi. SEM/EDS untuk mengetahui morfologi dan unsur kimianya. XRD untuk mengetahui fasa kristal yang terbentuk beserta prosentasenya. Semakin tinggi konsentrasi asam tartarat pada larutan menyebabkan massa kerak yang terbentuk semakin sedikit menurun hingga 80%. Ini berarti asam tartarat bisa menjadi aditif yang efektif untuk mengahambat kristalisasi CaCO3. Analisis SEM/EDS menunjukkan bahwa morfologi kerak ada yang berbentuk kubus (calcit), bola (vaterite dan jarum (aragonite). Analisis XRD menunjukkan fasa kerak adalah vaterite, aragonite dan calcite. Kerak mineral aragonit terbentuk karena pengaruh asam tartarat dan suhu. Hal Ini menunjukkan asam tartarat dapat menunda transformasi kerak kalsium karbonat menjadi fase stabil calsit.

Published: November 2020

Introduction: There are limited data on the relationship between the severity of community-acquired pneumonia (CAP), biomarkers of inflammation and coagulation as well.
The aim was to evaluate the association between the severity of CAP and risk of thrombosis in patients with moderate and severe CAP. To estimate the role of parameters of systemic inflammation, endothelial dysfunction, hemostasis, coagulation on different phases of treatment.
Materials and methods: The main group was 75 patients CAP. We divided the main group according severity: subgroup 1 – 41 patients with moderate CAP, subgroup 2 – 34 patients with severe CAP. Blood coagulation test, determination of biomarkers was performed at admission before starting of antibacterial treatment and after clinical stability on 7–10 day after hospitalization.
Results: We found that in both subgroup 1 and subgroup 2 the mean levels of CRP and fibrinogen were higher than in control group. Moreover, the mean level of
D-dimer was significantly higher and protein C (PC) was significantly lower in both subgroups in comparison with control group.
Normalization of PC is coming after 7–10 days of antibacterial treatment, vice versa ET-1, which reflects prolong endothelial dysfunction in patients with severe CAP.
Conclusions: patients with severe CAP have the high risk of thrombosis which can be associated with endothelial dysfunction; definition of such parameters as ET-1 and PC
can be useful for establishment of different coagulant disorders in patient with mild and moderate CAP, and their dynamic changes could be the initial point of prescribing or cancelling of anticoagulant treatment.

Published: November 2020

Introduction: Negative demographic trends are often associated with high levels of infertility, including male. In the modern literature there are data on morphofunctional
changes in various organs and tissues during inflammation of various origins, obtained in experiments on animals. At the same time, there are practically no studies on changes in the seminal glands in inflammation of different etiologies.
The aim of this study is to identify the morphofunctional features of the seminal glands in the dynamics of acute infectious (staphylococcal) inflammation in rats.
Materials and methods: Experimental studies were performed on 40 nonlinear male rats weighing 180-200 g. Microscopic and histochemical studies were performed on
the 7th, 14th, and 28th day.
Results: On the 7th day of staphylococcal inflammation, morphofunctional changes in the seminal glands were detected in rats in the form of a moderate rearrangement of
the spermatogenic epithelium, which was manifested by a decrease in Sertoli cells and the number of type A light spermatogonia along with an increase in the number of type
A dark spermatogonia and type B spermatogonia. The described changes were accompanied by a decrease in the metabolism of nucleoproteins in epithelial cells. On the 14th day, the morphological changes were characterized by a sharp decrease in Sertoli cells, the absence of type A light spermatogonia and an increase in the number of type A dark spermatogonia and type B spermatogonia. After 28 days, there is an increase in the number of tubules with the presence of type A light and dark spermatogonia, as well as single Sertoli cells, which indicates the restoration of the morphofunctional state of the seminal glands.
Conclusions: More pronounced compensatory-adaptive processes in the seminal glands occur within a period of 28 days from the start of modeling of staphylococcal inflammation.
The latter is confirmed by the appearance of various shapes and sizes of tubules with restored spermatogenic epithelium of various stages of development. The presence of type A light and dark spermatogonia indicates the reserve capacity of the seminal glands.

Introduction: The article highlights the basic principles of the use of animals in biomedical research raised the main problems of vivisection. It also suggests specific steps to enhance the humanization of this process. The conclusions are the following: it is very important to prevent cruelty to animals in the context of resolving bioethical and legal problems associated with the implementation of the principle of humanism and the protection of animal rights. Modern science and the practice of preclinical and clinical tests should be involved into serious challenge in order to improve and universalize the process of medical and biological research technology in vitro.
The aim:: The purpose of the article is to study the main international legal principles of using animals in biomedical experiments, as well as to determine the main problems
on this issue and to outline the ways to resolve them.
Materials and methods: The research material is a modern international regulatory framework that establishes the basic principles for the animals treatment. The methods of information retrieval, analysis, systematization, and generalization were used in this article.
Review: As it is well-known, human treatment of people begins with a human attitude towards animals. Nowadays the international community has adopted enough legal acts regulating the proper behavior with animals, including those specially cultivated for such studies (laboratory) when conducting biomedical experiments. Recently, both, in the national legislation of European countries and international legislation, there have been trends in the protection of both the general rights of animals as well as intensification of their protection in the field of biomedical research.
Conclusions: it is imperative, both at the international and national levels, to adopt programs for development and support of scientific study of the in vitro biosystems
introduction into the practice of toxicological studies.
At the national level, it is necessary to criminalize the violation of international standards for conducting biomedical research using animals, strengthen other types of responsibility, and create a special system of state bodies responsible for the policy of using animals for biomedical purposes and exercising control in this area. Both, international and national legislation should impose a direct ban on the use of in vivo technologies in case of the possibility of using in vitro technologies.

Artykuł bada dorobek artystyczny Aleksandry Śląskiej (1925–1989), aktorki teatralnej i filmowej, którą zapamiętano głównie jako specjalistkę od ról Niemek i arystokratek. Pokazuje okoliczności powstania tego stereotypu i rozbija go poprzez prezentację jej mniej znanego oblicza zawodowego. Zawiera analizę szerokiego wachlarza zróżnicowanych portretów kobiecych w jej wykonaniu, od kreacji w Niemcach Kruczkowskiego, przez rolę tytułową w Martwej królowej Montherlanta i Blanche w Tramwaju zwanym pożądaniem Williamsa, po ciekawe wcielenia komediowe, jak Elwira w Mężu i żonie Fredry. Śląska należała do pokolenia kształtującego polską kulturę w latach PRL-u i rozwijającego nowe media. Współtworzyła polską szkołą słuchowiska, polską szkołą dubbingu oraz Teatr Telewizji. Mitowi chłodnej, nieprzystępnej aktorki przeciwstawiono wizerunek wszechstronnie utalentowanej interpretatorki, wnikliwie studiującej złożoność ludzkiej natury, kobiety teatru realizującej się na wielu artystycznych polach.
Dramatopisarki w «republice braci»: Komu potrzebna jest (i jaka) kobieca historia polskiego teatru?
Authors: Świerkosz Monika
Published: November 2020

Artykuł omawia efekty projektu feministycznej historii teatru HyPaTia w kontekście szerszego zjawiska, jakim jest uprawiana od lat siedemdziesiątych XX wieku historia kobiet. Autorka stawia pytania o rewindykacyjny charakter podjętego w projekcie dialogu z kanonem i konstruktorski gest (od)tworzenia kobiecej historii polskiego teatru. Poprzez figury „siostry Szekspira” i „sióstr Hypatii” zwrócona zostaje uwaga na specyficzne uwikłanie biografii i twórczości dramatopisarek w patriarchalną ramę (określaną jako „republika braci”), które problematyzuje rozumienie emancypacji jako uwalniania się od męskiej opresji czy ucieczki na marginesy.
Le burn-out en réanimation : évaluation, prévention et dispositifs d’intervention
Authors: Fournier Alicia , Laurent Alexandra
Published: November 2020

Les professionnels de réanimation sont confrontés de façon répétitives et intenses à de nombreux facteurs de stress les rendant plus vulnérables au développement d’un burn-out. Le burn-out constitue le stade final d’une rupture d’adaptation suite à un déséquilibre entre les exigences professionnelles et les ressources de l’individu. Il affecte directement la santé mentale et physique des professionnels et est associé à une diminution de la qualité et de la sécurité des soins et à une augmentation des départs des professionnels les plus expérimentés pour d’autres services. En réanimation de nombreuses études ont été menées sur les professionnels et les organisations lancent des appels à l’action pour lutter contre cette souffrance au travail. Le présent article fait un état des lieux de la prévalence du burn-out en réanimation. Il présente également des dispositifs d’interventions individuelles et organisationnelles qui peuvent être utilisés pour prévenir et traiter le burn-out.
Application of contact-resonance AFM methods to polymer samples
Authors: Friedrich Sebastian , Cappella Brunero
Published: November 2020

Contact-resonance AFM (CR-AFM) has been used in recent years for the measurement of mechanical properties of rather stiff materials, such as ceramics or metals, but also of some polymers. Compared with other techniques providing information on the mechanical properties of a sample, notably force–distance curves, CR-AFM has a much shorter acquisition time. This compensates in part the incomplete theoretical understanding of the underlying physical phenomena and of factors influencing the measurements. A commonly used method to analyze CR data requires the determination of the relative position of the tip, the calculation of the normalized contact stiffness, and the use of a calibration sample for the calculation of the elastic modulus of the sample. In the present paper, we propose an alternative procedure, based on approximations of the equations describing the system, which allows one to determine the elastic modulus of the sample as a parameter of the fit of the CR frequency as a function of the load. After showing that CR modes including scanning under continuous contact wear and damage the sample and/or alter the surface roughness, the results of point CR measurements on bulk and thin films are presented. Though Young’s moduli of bulk polystyrene and poly(methyl methacrylate) could be determined through the presented analysis, it is concluded that CR measurements are not appropriate for polymer samples. Major drawbacks are the bad resolution for moduli lower than ca. 10 GPa and the lack of a comprehensive physical model accounting for many factors affecting the dynamic response of a cantilever in contact with a sample.

The technique of obtaining a new bioplastic material based on collagen, elastin and hyaluronic acid is described. The results of a study of the biomaterial structure and properties in order to assess the prospects for its further use in clinical practice are presented. Co-culturing of the bioplastic material and human fibroblasts did not reveal any its cytotoxic effects on cells in culture. It was shown that the biomaterial samples were able to maintain physical properties in the culture medium for more than 10 days. Due to its physical properties and structure, the use of created biomaterial provides effective conditions for good cell proliferation, which allows us to consider it as a promising biomaterial for use in clinical practice.

Introduction: Despite progressive statistics, the oral healthcare system suffers from an unevenly distributed workforce, lack of infrastructure, and reduced quality of dental education. As a result, dental graduates have decreased job satisfaction and limited career prospects. This article assesses the perceptions of dental graduates regarding their workforce skills, abilities, and employment preferences.
Methodology: This was a cross-sectional, questionnaire-based study targeting House-Officers from various randomly selected dental teaching institutes of Lahore. The study tool was a modified version of the questionnaire used by Manakil and George [13] and assessed the perceptions of dental graduates regarding their workforce skills and preferences. This study aimed to evaluate self-perceived confidence of new dental graduates, and investigate the relationship between gender perceptions.
 
Results: The sample size was of 256 House- Officers. Most participants were confident in their skills and abilities with 167 (65.4%) individuals confident in workforce integration, 166 (64.8%) confident in their patient management skills, 154(60.2%) confident in their interpersonal skills and 163 (63.7%) confident in their leadership abilities. Mentorship was considered to be crucial by 207 (80.9%) individuals. Two hundred and thirty-three (91%) individuals were willing for an additional year of internship and 174 (68%) participants chose a city-based employment. The government sector was the most preferred for employment by 122 (47.7%) individuals whereas research was least preferred. Conclusion:  It is imperative that career development and mentorship programs are put into practice, incentives are provided to work in rural areas and research culture is promoted.
