A song and a dance: Being inclusive and creative in practicing and documenting reflection for learning
Authors: Harvey Marina , Walkerden Greg , Semple Anne-Louise , McLachlan Kath , Lloyd Kate , Baker Michaela
Published: August 2021

As the number of students engaging in higher education increases, so too does their diversity. Additionally, there is growing pressure on universities to better prepare graduates for the varied paths they will pursue beyond study. In responding to these conditions it is important to develop pedagogical approaches that are both inclusive and engaging. One adaptation needed is in relation to the practice and documentation of reflection for learning. Reflection is widely practiced across higher education, and is favoured by the Work-Integrated Learning field for the ways it helps students make sense of their learning. The ongoing reliance on journals for practising and documenting reflection has several benefits; however, a diverse student body, engaging with diverse learning experiences, is likely to benefit from being offered diverse, flexible ways of engaging with reflective practice. Informed by student and practitioner reflective data gathered at an Australian university, this conceptual paper accepts the challenge to “disrupt” (deFreitas 2007) the text and “move beyond the diary” (Harvey et al. 2012) to present an argument for the value and role of alternative modes of reflection, spanning arts-based, embodied, mindful and technological approaches. Underpinning this advocacy of diverse mediums for reflection are the principles of inclusivity and universal design.
Teaching how to Listen. Blended Learning for the Development and Assessment of Listening Skills in a Second Language
Authors: Caruso Marinella , Gadd Colombi Anna , Tebbit Simon
Published: August 2021

This paper discusses the integration and effectiveness of blended learning for the development and assessment of listening skills in a second language. The development of oral abilities (listening and speaking) is one of the most challenging and neglected aspects of second language learning (Vandergrift & Goh 2012, Graham & Santos 2015). Listening comprehension work in particular is crucial in the early stages of second language acquisition, and, therefore, for ab-initio language students, for whom processing and decoding auditory input can be very challenging. In 2014 a set of online listening quizzes was created and integrated into two ab-initio Italian courses. The aim was to offer engaging, flexible listening comprehension practice and assessment, which would extend the students’ learning experience, stimulate their learning motivation and allow for a better use of face-to-face teaching in the classroom environment. Having conceptualised listening as a process rather than a product we designed tasks to teach learners how to listen, rather than merely test their comprehension. The validity of the quizzes as a means for the development of listening skills and as a tool for formative and summative assessment was subjected to systematic analysis via an online student survey. The large amount of data collected reveals that the quizzes were a key element in the development of listening skills and the delivery mode did not only meet the students’ learning needs but it was clearly preferred to in-class assessment.
Improving Digital Assessment Practice: A Case Study of a Cross-Institutional Initiative
Authors: Chase Anne-Marie , Ross Bella , Robbie Diane
Published: August 2021

Assessment practice is a crucial component of higher education learning and teaching, however many academic teachers lack formal teaching qualifications and often fall back on teaching and assessing the way they themselves were taught. Furthermore, with increasingly diverse student cohorts, larger classes and increasing components of teaching delivered online, it is unsurprising that students rate assessment as one of the poorest features of their learning experiences. For these reasons, understanding the specific contexts of assessment is important now more than ever. This paper will present the findings of a case study of a cross-institutional initiative aimed at exploring how to improve digital assessment practice by focusing on context, and encouraging and facilitating collegial collaboration. The aim of the case study was to progress a digital assessment project at an Australian higher education provider. Teams of staff from two higher education providers collaborated to develop and implement eight prototype assessments to reform digital assessment practices. The assessments were selected from online undergraduate academic subjects across a range of disciplines. Findings reveal that both staff and students felt that there were benefits to the cross-institutional collaboration. The resulting assessment was perceived as improving student motivation and engagement and more tailored for the online environment than the existing assessment.
Comparative Evaluation of Online and In-Class Student Team Presentations
Authors: Braun Michael
Published: August 2021

Student team presentations are commonly utilised in tertiary science courses to help students develop skills in communication, teamwork and literature research, but they are subject to constraints arising from class size, available time, and limited facilities. In an alternative approach, student teams present online using a variety of tools, such as screencast and blended media, but it is not clear whether this offers an authentic alternative to in-class experience. In this study, the two modes of presentation were compared in terms of student perceptions and academic performance. A survey probed students’ familiarity with digital technology, presentation anxiety, and differential perceptions of the two modes. Aside from a confirmation bias, no significant difference was found between those who presented in class and online. In a notable exception, a clear asymmetry appeared when students were asked to choose a mode for a future presentation: none of the online presenters opted for the in-class mode while a third of in-class presenters selected the online mode. Presentation anxiety was similar for in-class and online presenters and was insensitive to gender and familiarity with English. No significant difference was detected between the modes in terms of academic performance.

Published: August 2021

This research is motivated by the Covid-19 pandemic in Indonesia which has an impact on the economic inequality of society and also the impact of education which hinders the learning process. This has led to a new learning method called online learning or distance learning which is now being implemented by the government. Students are required to take online learning because the Covid-19 pandemic does not allow students to take face-to-face learning with the teacher. The purpose of this study is to analyze online learning in Upper Middle School Students in the Mranggen District. The method used in this research is the descriptive qualitative method. Test the validity of the data using validity and credibility tests. The data analysis used is reduction, display data, and conclusion drawing/verification. The results of this study indicate that online learning or distance learning has many advantages and disadvantages experienced by students, parents, and physical education teachers in SMA Mranggen District. In its strength, students know more about information technology or what is called IT. The drawback of online learning itself is that the limited facilities and infrastructure that are owned by the teacher and students make learning less optimal. The conclusion of this research is that research can get results that the Covid-19 pandemic has advantages and disadvantages of online learning from Physical Education and Health in Mranggen District.
Second-Language Reading Process for Professional English: A Case Study
Authors: Chen Che-Han
Published: August 2021

Although much research on English for specific purposes (ESP) has been conducted, little focus has been placed on investigating the mechanisms involved in ESP readers’ comprehension process. This case study explored the reading process that characterizes a competent ESP reader’s comprehension. A juris doctor student attending a major university in the United States was selected for the case study. Qualitative data were gathered through a semi-structured interview, recall protocol, and document analysis, and were thematically coded. The findings revealed the following: (a) The professional domain determines the major purposes of ESP reading. (b) Institutional demands and inadequate L2 proficiency within the target discourse prevent background knowledge in the first language (L1) from being transferred to L2 texts are the major sources of comprehension difficulty. (c) Three strategies can be used to overcome such difficulties. First, schemata (background knowledge) in L1 can facilitate comprehension and enhance the reading process. Second, genre knowledge learned in L1 can be used to dissect the information structure of L2 texts. Finally, the use of L1-based materials can help to overcome the comprehension difficulties arising from the L2 material. The implications for L2 reading instruction and future ESP reading research are discussed.

Influence of hard segments content on thermal, morphological and mechanical properties of homo and co-polyurethanes: a comparative study
Authors: Alobad Z.K. , Albozahid M. , Naji H.Z. , Alraheem H.S. , Saiani A.
Published: August 2021

Purpose: This work aims to study the effect of hard segments (HS) content on the thermal, morphological and mechanical properties of polyurethane polymers based on 1.5 pentanediol chain extenders. Design/methodology/approach: Two comparable series of polyurethanes were synthesised including homo-polyurethane (Homo-PU) and copolyurethane (Co-PU). The Homo-PU consists of 100% wt. of hard segments (HS). The Co-PU composes of 30%wt. of soft segments (SS) using a poly(ethylene glycol)-block-poly(propylene glycol)-blockpoly( ethylene glycol) material. The effect of hard segments content on the morphology of Homo-PU and Co-PU was also studied. Findings: The Homo-PU and Co-PU materials show three distinct degradation steps with the higher thermal stability of the Co-PU compared to the Homo-PU. Enthalpy of fusion (ΔHM) and heat capacity (ΔCP) of polyurethane (PU) samples decrease with decreasing HS content. In the cooling cycle, the higher exothermic peak of crystallization is observed in the Co-PU. In contrast, the cold crystalline peak is observed in the 2nd heating cycle of the Homo-PU. Melting temperature (TM) increases with increasing SS content. Glass transition temperature (Tg) of PU samples shifts to higher temperature with increasing HS content. Storage modulus (E’) of the Co-PU is higher than E’ of the Homo-PU. All N-H groups in PU samples are hydrogen-bonded, whilst most of the C=O groups are hydrogen-bonded. The degree of hydrogen bonding in PU samples decreases with decreasing HS content. The Homo-PU shows better hardness than the Co-PU and higher brittleness at low temperature. WAXS results of the Homo-PU display better crystallinity compared to the Co-PU. Research limitations/implications: The main challenge in this work was how to synthesis Thermoplastic polyurethanes (TPUs) with specific properties to compete other common polymer such as Polyamides (PA) and Polypropylene (PP).Practical implications: Thermoplastic polyurethanes (TPUs) can be used in various application such as backageing, foot,automobiles and constructions. Originality/value: A new type of TPUs that synthesized using different type of chain extender (1.5 pentanediol). Two different types of TPUs were synthesized one contained 30% SS and 70% HS and a second one contained 100% HS.

Authors: Tsamroh D.I.
Published: August 2021

Purpose: To analyze and estimate the strength of duralium rivets which had been treated by using multistage artificial aging compared with duralium that had not been treated. This processwas necessary to be conducted in riveting process effectively. Duralium has been widely used in aerospace industry, one of duralium usage in aerospace industry is aircraft fittings such as rivet. Riveting is one of method that used for joining airframe structural components. During riveting process, the load transfer causing stress that led to the fatigue. Riveting process also causes deformation on the rivet and sheet metal. Deformation that occurs on the rivet will affect the performance of rivet structure. Thus, duralium rivet was analyzed its total deformation, shear stress, and its equivalent stress Von Misses. Design/methodology/approach: that used in this study was finite element analysis. Geometry of rivet that used in this study was drawn by using Autodesk Inventor Professional 2018. While total deformation, shear stress and equivalent stress Von Mises on duralium rivets were found out by using ANSYS Workbench 18.1. Findings: Comparison result was obtained between duralium rivet with and without treatment of multistage artificial aging. The result shown that total deformation, shear stress and equivalent stress Von Mises which obtained by duralium rivet with multistage artificial aging had the lower value than duralium rivet without multistage artificial aging. Duralium rivet with multistage artificial aging could be used as aircraft fitting which had the higher strength. Research limitations/implications: Direct experiment on duralium rivet had not been done yet, this study only did simulation based on data that obtained form previous research that had been conducted by the researcher. Practical implications: Duralium rivet with multistage artificial aging had lower value on total deformation, shear stress, and equivalent stress Von Misses, thus duralium rivet with multistage aritificial aging had a higher strength.

Published: August 2021

Purpose: The article contains the results of research and development of a system for active noise damping of an automobile engine. The proposed system of active noise suppression can significantly reduce the sound pressure level in the frequency band up to 500 Hz. The robotic principle of the developed system is based on the addition of an additional buffer tank with a variable volume in the silencer system. The use of high-temperature sensors with strain gauges based on silicon microcrystals to obtain information on the parameters of sound vibrations arising during the exhaust gas outflow made it possible to create a control system for changing the volume of the buffer tank. The results of testing the proposed system of active noise suppression of an internal combustion engine are presented. Design/methodology/approach: The active noise suppression system based on the Helmholtz resonator used tools to control general noise levels, experimental tests, complex mathematical modelling of acoustic processes in Solidworks, taking into account the conditions of propagation and attenuation of sound energy by intermediate closed volumes. Findings: The use of an additional resonator chamber with variable volume in the exhaust muffler of the internal combustion engine allowed to reduce the resonant phenomena in the zone of low-frequency pulsations of exhaust gas pressure from 57 Hz to 43 Hz at frequency drift in the range of 310… 350 Hz, which significantly improved its noise characteristics. Research limitations/implications: For further research, to improve the characteristics of the active noise suppression system, it is advisable to consider the use of several inadditional cameras of the Helmholtz resonator and to clarify the algorithm of the controller in transient modes of engine operation. Practical implications: The developed design of active noise reduction is simpler in comparison with analogs and allows reducing the noise of exhaust gases in a low-frequency range. Originality/value: To reduce the noise, a variable-volume Helmholtz resonator was used, the efficiency of which is provided by high-temperature sensors of the original design.

Background: Considering the excellent safety profile and the high efficacy rates, great benefits were expected with the availability of the new direct-acting antivirals (DAAs) in treating hepatitis C virus (HCV) infection. Following the publication of two articles in 2016 on the high incidence rates of hepatocelullar carcinoma (HCC) following DAAs, several papers revealed contradictory results, thereby casting shadows on the role of DAAs in hepatocarcinogenesis. Objectives: The present study aimed to assess the incidence and risk factors of HCC in patients with HCV genotype 1b infection and compensated cirrhosis with the sustained virological response (SVR) following DAAs. Methods: This multicentric prospective study encompassed 479 patients with HCV genotype 1b compensated cirrhosis treated with paritaprevir/ritonavir/ombitasvir and dasabuvir (PrOD) +/- ribavirin (RBV) for 12 weeks in two tertiary centers in Northeastern Romania. The patients were prospectively followed up in the Institute of Gastroenterology Iasi, Romania, from November 2015 to December 2020. Results: During the follow-up period (mean 60.11 ± 3.87 months), 23 patients (4.8%) developed HCC. The 1-, 3-, and 5-year cumulative incidence rates of HCC were 1.1, 1.9, and 2.6%, respectively. At the time of the diagnosis, 15 patients (65%) had a single tumor, 12 patients (52.2%) were within the Milan criteria, and nine persons (39%) had Barcelona liver cancer stage 0-A. In this regard, the mean AFP level was 35.3 ± 93.1 ng/mL. A multivariate analysis, age above 65 years, and a cutoff point of AFP ≥ 10 ng/mL at the end of treatment were independent factors associated with HCC. A majority of the patients (n = 11, 47.8%) received curative treatment by surgical resection. In this study, histopathological examination identified a moderately differentiated tumor (G2) in 5 patients, five patients had a poorly differentiated tumor (G3), and only one patient had a well-differentiated tumor (G1). Conclusions: Our study revealed no evidence of the high incidence rate of HCC after the long-term follow-up of patients with HCV-related liver cirrhosis and SVR following DAA treatment. However, the cumulative 5-year risk remained above the cutoff point, and this makes the HCC screening cost-effective. The HCC occurrence appears to be associated with aging and a moderately increased AFP level at EOT (≥ 10 ng/mL).

Published: August 2021

Background: Social-cognitive theorists suggest that cognitive-emotional factors play essential roles in academic outputs like academic engagement. Objectives: The purpose of the present study was to investigate the relationship between social achievement goals and academic engagement by mediating role of academic and social positive emotions. Methods: The method of present study was descriptive cross-sectional study based on correlational research. Using cluster multi-stage sampling method, this study included 566 undergraduate students (278 male and 288 female) in the first semester of 2018. The research instruments were Social Achievement Goals scale, Academic Hope scale, Admiration scale, and Academic Engagement inventory. Data were analyzed using correlation matrix and structural equation modeling. Results: Results of analyzing data showed that social development goal had a positive indirect effect (β = 0.41, P = 0.01) on academic engagement through academic hope and admiration. Also, social demonstration-approach goal had an indirect and negative effect (β = -0.08, P = 0.01) on academic engagement by the mediating role of admiration. Finally, the research model was able to explain 31% of the variance of academic engagement with two latent variables of social achievement goals and academic and social positive emotions. Conclusions: In general, social achievement goals and positive emotions significantly explained the variance of academic engagement. The findings provide supportive evidence for how motivations and emotions can affect academic engagement.

Published: August 2021

Background: Adnexal mass is one of the most common gynecologic diseases among women of all ages. Methods: In this cross-sectional study, we enrolled 126 patients with large adnexal masses (≥ 10 cm) managed by laparoscopic surgery during 2013 - 2020. The rates of intraoperative complications, conversion to open surgery, and incidence of cancer were assessed. Results: Mean mass size was 15.08 ± 5.03 in all participants without significant difference based on the tumor type (P = 0.624). Mean age and operation time were higher in the malignant type compared to the benign type (P < 0.001). Type of surgery and frequency of intraoperative complications were also different among patients with different tumor types (P < 0.001 and P = 0.816, respectively). Conclusions: Our study showed that large adnexal tumors can be operated by laparoscopic approach, while the most important factor for increased surgical complications and duration was malignancy.

O TRIBUNAL DE NUREMBERG E A TEORIA PURA DO DIREITO
Authors: Borrmann Ricardo , Cruz Eugeniusz
Published: August 2021

Este ensaio aborda o panorama histórico em que se desenvolveram duas teorias que viabilizaram, no contexto do direito internacional, a responsabilização pelas violações de direitos humanos ocorridas durante a Segunda Guerra Mundial. A análise focaliza (I) a Teoria Pura do Direito (TPD) de Hans Kelsen e (II) a “Fórmula de Radbruch”, problematizando a acusação ao positivismo jurídico de que este compactuou com o regime nazista, deixando os juízes alemães de “mãos atadas”. A hipótese é a de que o vínculo do positivismo de Kelsen com os crimes cometidos pelo regime nazista não encontra sustentação (I) nem no processo histórico, portanto, em fatores externos à sua teoria, ligados ao percurso intelectual de Hans Kelsen como jurista e teórico do Direito, (II) nem nos pressupostos de sua TPD. O estudo analisa ainda os processos de Nuremberg em sua conjuntura histórica, a adequação das críticas de Radbruch ao positivismo kelseniano, bem como as críticas de Kelsen ao Tribunal de Nuremberg.

Published: August 2021

Purpose: the objective of this study is to analyze the career anchors (Schein, 1974) of university students involved in social activities. Design/methodology/approach: we chose a quantitative descriptive approach, with the application of a questionnaire to 68 young students participating in the CHOICE ambassador program. Findings: results showed the predominance of the service and dedication to a cause anchor, and the relevance of acting in student and volunteer organizations. The career anchor acts as an influencing factor for the interest in social businesses, while previous involvement in other social activities (volunteering and student entities) seems to be the indicator that shows how much the individual will effectively move in the direction of social businesses. Originality/value: this result demonstrates the existing alignment between the search for a purpose and working in social businesses. Although the involvement in social activities is becoming increasingly present in university life, companies still do not know how to determine the value of these experiences. Therefore, we emphasize the importance of studying this phenomenon and bringing information that allows these barriers to break, after all, society increasingly needs new solutions to social problems.
INFLUÊNCIAS DA TELEVISÃO NA PRODUÇÃO BRASILEIRA DE DOCUMENTÁRIOS DE PERIFERIA
Authors: Souza Gustavo , Alves-Silva Jamilson José
Published: August 2021

Com cerca de 20 anos de existência, a produção audiovisual periférica tem, na sua origem, uma forte influência da televisão tanto em termos narrativos quanto estéticos. O objetivo deste trabalho é voltar aos “primórdios” e debater como as oficinas e coletivos de realização incorporaram esse referencial. Partimos da hipótese de que tal referência se manifesta de duas formas: uma inclusão praticamente literal dos referenciais televisivos, por meio do docudrama e de reportagens de TV, e outra que tenta contemplar a estética televisiva e a cinematográfica. Esse debate permite também relativizar as supostas hierarquias existentes entre cinema e televisão, de modo a ver essas duas mídias como contíguas e não como discrepantes.
REDRESSING DIGITAL ORIENTALISM: VIETNAMESE CULTURAL PROFESSIONALS’ DIGITAL WORK DURING THE COVID-19 PANDEMIC
Authors: Duester Emma , Teague Michal
Published: August 2021

The current study investigates how digital technologies can potentially be used to re-orientate the global narrative on Vietnam, overcome an imbalance in representation and help redress digital orientalism. Global digital technologies allow Vietnamese cultural professionals to reach beyond the borders of their nation and to become part of the global art world. With this,they can participate in the production, dissemination, and circulation of discourses on art and culture globally. In doing so, they can redress digital orientalism by contemporizing narratives on Vietnam. However, there is an underlying tension, as the very means by which their voicesare heard is achieved by using global (western) technologies, tools and platforms. The research uses a digital ethnography of the Facebook pages of 7 contemporary art spaces in Hanoi and 20 semi-structured interviews with art and cultural professionals in Hanoi. The interviews were carried out during the Covid-19 Pandemic and addressed its impact and use of digital technology in their work during this time.
Management of Class II Division 1 Subdivision malocclusion using unilateral bicuspid extractions and fixed functional appliance: A Two Year Follow-Up
Authors: Kohli Sarvraj , Kohli Virinder , Kochhar Gagan Deep
Published: August 2021

Introduction:  Management of Class II Subdivision cases pose a clinical dilemma and require a careful diagnosis to ascertain the source of asymmetry. Various treatment modalities involving: different protocols of tooth extractions; molar distalization; fixed functional appliances or orthognathic surgery have been proposed for the same.

Objective:       This article reports a unique approach for management of a severe skeletal Class II with Angle’s Class II Division 1 subdivision malocclusion using unilateral bicuspid extractions in mandibular and maxillary arches  and a fixed functional appliance.

Results:         A 13 year 1 month old male in CVMI transition stage was successfully treated. Extraction of #44 was done to alleviate crowding in the mandibular anterior region and #15 was extracted to protract #16 to achieve a Class II molar relationship. A pre-functional Class II molar and canine relationship with co-incident midlines was achieved. The functional phase consisted of a fixed functional appliance (Forsus FRD) for mandibular advancement to correct the severe skeletal Class II. Class I molar and canine relationships were achieved with reduction of facial convexity and overjet. Result remained stable 24 months after treatment. The improvement can be quantified by the reduction in scores of orthodontic indices measured pre and post treatment.

Conclusions:                        Management of Class II subdivision malocclusion requires careful planning. This paper presents a unique approach utilizing unilateral extractions and fixed functional appliance to address severe skeletal Class II discrepancy and the subdivision dilemma.
Evaluation of the effects of cotton roll-biting on debonding pain: a split-mouth study
Authors: Celebi Fatih
Published: August 2021

Introduction: Debonding pain is an unpleasant sensation that is frequently encountered during debonding procedure.

Aim of the study: To investigate the effectiveness of cotton roll-biting on pain caused by the debonding procedure.

Materials and methods: 102 patients (61 females, 41 males) who were at the debonding stage in orthodontic treatment were included in the research. The study was planned using a split-mouth design: one side of the jaw was the study, and the other side was the control. The anxiety level of participants was measured before debonding. On the study side, debonding was performed while patients were biting a cotton roll. On the control side, debonding was implemented as a routine debonding procedure. Study and control sides were assigned differently in each successive patient. The debonding pain of each tooth was recorded using the Visual Analog Scale prepared separately for each tooth. Shapiro–Wilk and Mann–Whitney U tests were used for statistical analysis. For both gender groups, patients were sequenced according to the average amount of pain per tooth. Subsequently, statistical analysis was repeated by using 50% of patients suffering more pain.

Results: In the lower second premolar tooth, a statistically significant difference was detected. Pain scores were statistically higher in the study side for this tooth. No statistically significant differences were found for all other teeth.

Conclusions: Cotton roll-biting has no alleviating effect on debonding pain. When debonding is performed gently using a squeezing action without applying torsional forces, additional pain relief methods are not required.

To promote the low-carbonization of rural logistics, the embeddedness among low-carbon rural logistics potential (LRLP), low-carbon rural logistics strength (LRLS) and environmental regulations (ERs) was clarified by using the analytical paradigm of impetus–basis–target. According to the embeddedness, an evolutionary framework of the low-carbon rural logistics system was constructed to analyze the evolutionary process of this system. Then, a three-dimensional evolutionary equation of the low-carbon rural logistics system was proposed based on the evolutionary framework, and the evolutionary threshold criterion of the system was obtained through the stability analysis of the evolutionary equation. The interaction mechanism within the evolutionary process of the low-carbon rural logistics system in China was verified through data simulation in MATLAB. The results show that in an environment with lower ERs, the effect of simply relying on LRLS to promote the sustainable development of low-carbon rural logistics is not obvious, and the overall effect is not significant. In the long term, under the influence of different external control variables, LRLP plays a pivotal role in evolution, and improving LRLP is conducive to promoting the sustainable development process of low-carbon rural logistics.

In this work, several studies of aging pipes have been compiled and, starting on the basis of circulating flow through a pipe of t years of age is based on the inner diameter and driving age, some design life tables have been made corresponding to the main materials and components of pipes specifically: iron, steel, concrete, fibre cement and plastics, determining the corresponding ageing by multiple linear regression equations, obtained for all these materials. Several proposals of analytical configuration of the mathematic functions of aging (flow-time) that can be useful for the study and prevention of this phenomenon are also made.
THE APPRENTICESHIP IN CRAFT GUILDS IN PREINDUSTRIAL EUROPE: A MODEL FOR ENGINEERING EDUCATION IN THE EUROPEAN HIGHER EDUCATION AREA
Authors: MARTIN LLORENTE OSCAR
Published: August 2021

This work aims to carry out a comparative study between the apprenticeship system in the craft guilds in preindustrial Europe and the educational methods used in the European Higher Education Area (EHEA), with the aim of highlighting the role, within the field of engineering education in the EHEA, of the practice-driven approach (learning by doing), which yielded excellent results during centuries to craft guilds, since their institutionalized apprenticeship system was one of the reasons for their long-term survival. The transmission of technical skills and associated innovation were effectively supported by craft guilds but not as a main objective and even, sometimes, as a cause of undesired effects (formation of future competitors, revelation of secrets or shift of control over the production process from the owners of skills to the owners of capital. It has been demonstrated that both the organizational modalities or scenarios and the educational methods of the EHEA (except the binomial scenario-method formed by the theoretical class and the master lecture) used in engineering education, have a clear precedent in the preindustrial craft guilds, which emphasize the learning process instead of the teaching process and established, several centuries in advance and without intending to, a model for the EHEA.

Primary palatoplasty for cleft palate places patients at high risk for scarring, altered vascularity, and persistent tension. Palatal fistulas are a challenging complication of primary palatoplasty that typically form around the hard palate–soft palate junction. Repairing palatal fistulas, particularly wide fistulas, is extremely difficult because there are not many choices for closure. However, a few techniques are commonly used to close the remaining fistula after primary palatoplasty. Herein, we report the revision of a palatal fistula using a pedicled buccal fat pad and palatal lengthening with a buccinator myomucosal flap and sphincter pharyngoplasty to treat a patient with a wide palatal fistula. Tension-free closure of the palatal fistula was achieved, as well as velopharyngeal insufficiency (VPI) correction. This surgical method enhanced healing, minimized palatal contracture and shortening, and reduced the risk of infection. The palate healed with mucosalization at 2 weeks, and no complications were noted after 4 years of follow-up. Therefore, these flaps should be considered as an option for closure of large oronasal fistulas and VPI correction in young patients with wide palatal defects and VPI.

Based on the global surface temperature data, the global temperature correlation networks corresponding to El Niño and La Niña events are constructed respectively, and the differences in their effects on the network topological structure properties are analyzed. The results show that compared with the La Niña temperature network, the correlation between grid temperature series in El Niño temperature network is weakened, and the connectivity of the network is significantly reduced, especially in the tropical region and the southern temperate region. The network connectivity degree of equatorial eastern Pacific, equatorial western Pacific, equatorial Indian Ocean and equatorial Atlantic Ocean are relatively large, and the decrease in El Niño network is notable. They are also the four key regions leading to the differences of the structural characteristics of the two types of network. On this basis, the reason for the difference between the two types of network characteristics is preliminarily discussed. With the increase of SST in Niño3.4 region, the SST in equatorial eastern Pacific, equatorial Indian Ocean and other areas rise, which strengthenes outgoing long wave radiation and convection activities, and the interaction between low latitude and mid-latitude areas, and the variance of air temperature changes in the north and south temperate regions increase. As a result, the correlation between the temperature series of the four key regions and the rest of the world is weakened, therefore the connectivity of the global grid temperature network is reduced.

The method of estimating matched field power solves the problem that the traditional method of estimating power under the assumption of spherical or cylindrical wave is greatly affected by the shallow water waveguide. However, the accuracy of the matched field power estimation is seriously affected by the environmental uncertainty. In this work, the environmental sensitivity in source power estimation is defined, and the loss of the source power estimation performance is quantified when the environment is uncertain. The relation between the loss of the source power estimation performance and the estimation deviation of the acoustic transfer function is derived by using the modulus deviation and the angle between the estimated acoustic transfer function and the ideal value. On this basis, we study the mechanism of the influence of environmental uncertainty on source power estimation, and the influences of water depth, sound speed of water and sound speed of sedimentary layer on the estimation of source power. The results show that the influences of different environmental parameters on the modulus are small, and the decline of the power estimation performance is mainly due to the fact that the angle varies greatly. The change of water depth has the most significant influence on the power estimation results, and the change of sound speed of sedimentary layer exerts little influence on the power estimation results. Beside the water depth, the change of sound speed of water has a greater influence on the power estimation results at high frequencies.
