Transformation of Rural Teachers Earning Graduate Degrees
Authors: Santo Susan
Published: February 2021

This study tells the stories of four successful graduate students within a cohort of learners who were earning graduate degrees in technology for education and training by distance. The students were practicing teachers in the Dakota Interactive Academic Link (DIAL) consortium. Courses were offered by the University of South Dakota, using videoconferencing through the statewide Digital Distance Network (DDN) and WebCT asynchronous discussions. Mezirows 1991 theory of transformative learning suggests that adult learners may experience a transformational experience. Results showed that the four study participants experienced major changes in their way of thinking about learning and themselves. Conducting longitudinal studies in which adults are interviewed throughout their graduate school experience is recommended.
The Rise and Fall of a Songwriting Partnership
Authors: DeVries Peter
Published: February 2021

The working relationship of two novice songwriters is examined in this ethnographic study, which highlights the importance of common goals and values in a songwriting collaboration. Stemming from this core there are a number of sub-themes: the pair saw a popular song as consisting of melody, harmony, and lyrics; they played on the strengths and offset the weaknesses of each others songwriting skills; both writers valued originality; and they believed songwriting had a mystical element to it. Finally, it will be shown how conflict in their status as writing partners resulted in the demise of the collaboration. The difficulty of being a participant observer researcher when only two people are being observed is also discussed.

Published: February 2021

Aeromonas spp. are prevalent pathogens in farmed eel, which induce highly infectious diseases, such as hemorrhagic septicemia and gill-rot disease. Research on the application of ethanol and water extracts from traditional Chinese herbs in controlling the diseases has increased. However, the exact antibacterial components in majority of these herbs were not well-studied. Four fractions or components were isolated from Terminalia chebula Retz. ethanol extract in our previous study. In the present study, their antibacterial effects on A. hydrophila and A. veronii were assessed using microcalorimetry. The results showed that component III (a single chemical constituent, gallic acid) had the strongest antibacterial effect compared with three other fractions. The inhibitory effect was enhanced as the concentration of component III increased, and the minimum inhibitory concentrations of component III to A. hydrophila and A. veronii were found to be 0.56 mg/ml and 0.74 mg/ml respectively. This is the first study in which the antibacterial component of T. chebula extract on aquatic bacteria growth was screened and determined by microcalorimetry.

Authors: Anwar Mohammed Omer , Al Omran Yasser , Al-Hindi Saeed
Published: February 2021

Background: A modified laparoscopic pyloromyotomy (LP) technique may provide an alternative to treating infantile hypertrophic pyloric stenosis (IHPS) by improving operative timing with reduction of postoperative complication rates, compared with a three-port trocar system.Methods: Thirty-three infants were treated with IHPS at a single-centre between January 2002 and December 2011. The local surgical incision to the pylorus was performed according to Ramstedt’s pyloromyotomy; but with a two-port trocar system (umbilical and right lower abdominal crease ports), following a controlled stab wound into the epigastric region and a 3mm incision to allow introduction of ophthalmic knife. With the aid of atraumatic forceps and camera guidance, the ophthalmic knife was used to carefully incise the seromuscular layer, which allows improved manual tactile sensation compared to ergonomic laparoscopic spreaders. A Benson pyloric spreader was then used to further separate the pyloric muscle layer to complete the procedure.Results: In all 33 infants treated, LP was safely performed with no evidence of duodenal or mucosal perforation with complete pyloromyotomy achieved in each case. The postoperative course was rather uneventful apart from an umbilical wound infection.Conclusion: This modified approach is simple, safe and allows improved operative timing, whilst increasing surgeon’s confidence by tactile sensation.

LİBERALİZMİN TEMELLERİ: FAYDACILIK VE DOĞAL HUKUK ÜZERİNE BİR İNCELEME
Authors: AYDAR Selahattin
Published: February 2021

Son birkaç yüzyılda Avrupa ve Amerika’da siyasi ve iktisadi açıdan geniş anlamda kabul gören liberalizm hem etik ve hem de siyaset felsefesinin yüzyıllar boyunca geliştirdiği fikirlere dayanmaktadır. Özellikle klasik liberalizmin mirasçısı hükmünde olan 20. yüzyıl liberalizmi genel hatlarıyla doğal hukuk teorisinden türemiştir. Buna göre insanın doğuştan sahip olduğu ve devredilmesi mümkün olmayan yaşama, özgürlük ve mülkiyet gibi temel hakları vardır ve her türden siyasal oluşum bu hakları gözetip korumakla yükümlüdür. Ayrıca pozitif hukukun yine doğal hukuka bağlı olarak geliştirilmesi öngörülür. Öte taraftan felsefede etik bir öğreti olarak gelişen faydacılığın da liberalizmin gelişiminde önemli bir yere sahip olduğunu söylemekte herhangi bir sakınca görünmemektedir. Yöntem açısından doğal hukuk teorisi ile farklılık gösterse de esasında faydacılık kuramı da insanı merkeze alır, onun bireyselliğine ve özgürlüğüne dayanan bir dünyanın yaşanılabilir olduğuna inanır. Dolayısıyla genel hatlarıyla liberalizm, iki temel doktrin yani doğal hukuk ve faydacılık üzerine gelişmiş bir öğreti olarak kabul edilmektedir.

Building with Nature perspectives
Authors: Van Bergen Janneke , Nijhuis Steffen , Brand Nikki , Hertogh Marcel
Published: February 2021

This publication offers an overview of the latest cross-disciplinary developments in the field of Building with Nature (BwN) for the protection of coastal regions. The key philosophy of BwN is the employment of natural processes to serve societal goals, such as flood safety. The starting point is a systems-based approach, making interventions that employ the shaping forces of the natural system to perform measures by self-regulation. Initial pilots of this innovative approach originate from coastal engineering, with the Sand Motor along the coast of South Holland as one of the prime examples. From here, the BwN approach has evolved into a new generation of nature-based hydraulic solutions, such as mangrove forests, coastal reefs, and green dikes.
Engineering roles in Building with Nature interdisciplinary design
Authors: Klaassen Renate , Kothuis Baukje , Slinger Jill
Published: February 2021

Building with Nature (BwN) infrastructure designs are characterised by disciplinary integration, non-linearity, diverse and fluid design requirements, and long-term time frames that balance the limitations of earth’s natural systems and the socio-technical systems created by humans. Differentiating roles in the engineering design process may offer strategies for better solutions. Four complementary engineering design roles were distinguished, namely: Specialists, System Integrators, Front-end Innovators, and Contextual Engineers. The key research question addressed in this paper asks, how can the introduction of engineering roles enhance interdisciplinary processes for BwN design? Three Building with Nature design workshops with international groups of students from multiple disciplines and various education levels provided the ideal context for investigating whether engineering roles enhance such interdisciplinary ways of working. Results indicate that the application of engineering roles in each of the three workshops indeed supported interdisciplinary design. A number of conditions for successful implementation within an authentic learning environment could be identified. The engineering roles sustain an early, divergent way of looking at the design problem and support the search for common ground across the diverse perspectives of the team members, each bringing different disciplinary backgrounds to the design table. The chapter closes with a discussion on the value of engineering design roles and their significance for the Building with Nature approach.
A novel coastal landscape model for sandy systems
Authors: Luijendijk Arjen
Published: February 2021

A common measure to mitigate erosion along sandy beaches is the implementation of sand nourishments. The design and societal acceptance of such a soft mitigation measure demands information on the expected evolution at various time scales ranging from a storm event to multiple decades. Process-based morphodynamic models are increasingly applied to obtain detailed information on temporal behaviour. This paper discusses the process-based morphodynamic model applied to the Sand Motor and how the morphodynamic forecasts have benefitted from the findings of an interdisciplinary research program called NatureCoast. The starting point is the morphodynamic prediction of the Sand Motor made for an Environmental Impact Assessment in 2008 before construction began. After the construction, the model computations were optimized using the first-year field measurements and insights by applying advanced model features. Next, an integrated model was developed that seamlessly predicts the morphodynamics in both the subaqueous and subaerial domains of the Sand Motor. Decadal predictions illustrate the need to be able to resolve the marine and aeolian processes simultaneously in one modelling framework in the case of dynamic coastal landscapes. Finally, a novel morphodynamic acceleration technique was developed that allows for predicting the morphodynamics for multiple decades while incorporating storm events in one simulation. Combining the above-mentioned developments has led to a unique, open-source, process-based landscape tool for (complex) coastal sandy systems, which can stimulate further collaboration between research communities. Moreover, this work demonstrates the evolution from mono- to interdisciplinary forecasts of coastal evolution.

Authors: Maddalone Marcello , Bianco Edoardo , Nanussi Alessandro , Cortese Marina , Varisco Margherita , Scali Jessica
Published: February 2021

Aim and objective

The purpose of this work is to investigate by electromyographic (EMG) surface analysis whether and how the variations in the occlusion due to the correction of the posterior crossbite using a rapid palatal expander (RPE) is accompanied by changes in the activity of the elevator muscles in the pediatric patients.

Background

Posterior crossbite is a disgnathic jaw relationship common in patients undergoing growth. In the last 10 years, several studies demonstrated the effectiveness and reproducibility of surface EMG in the objective evaluation of temporal muscle and masseter activity and how this evidence can be an interesting aid in dental clinical practice.

Case description

The case subject BF is an 11-year-old boy with a right I class relationship and a left II class relationship treated with a rapid palatal expansion protocol with a turn of the transversal screw twice a day (0.25 mm each turn) for a week. In this case report, EMG was used to evaluate the temporal muscle and masseter activity immediately before, immediately after, and 4 months after the RPE protocol.

Conclusion

Four months after the treatment, a condition of well-being and neuromuscular equilibrium such as that of starting was preserved.

Clinical significance

Electromyography is a noninvasive exam which evaluates the masticatory muscle activity by facial application of electrodes on masseter and temporal muscles. It can be an interesting aid in orthodontic clinical practice to evaluate preservation of a good muscular balance following orthodontic and orthognathic movements.

Published: February 2021

Aim and objective

To evaluate the possible genotoxic effect of X-rays on buccal mucosa while exposing to dental panoramic radiography using micronucleus test.

Materials and methods

The study group comprised of 30 healthy subjects, 15 males and 15 females, aged between 24 years and 65 years. Samples were obtained from the exfoliated oral mucosa cells of buccal mucosa before and 12 days after exposing the patients to panoramic radiography.

Results

The study reported that there was no significant increase in the number of micronuclei cells present before and after panoramic radiography. Positive correlation existed between age with pre- and postexposure micronuclei.

Conclusion

Diagnostic dental panoramic radiograph does not induce micronuclei in the target buccal epithelium cells. A positive correlation between age and micronuclei frequency was established.

Clinical significance

Panoramic radiographs does not induce cytotoxicity but increase frequency may be vulnerable to genotoxic effects in buccal mucosal cells. Hence, dental radiographs should be prescribed only when necessary.

Aim

This study aims to evaluate the difference in fracture resistance of the short fiber-reinforced composite (SFRC) thickness as intermediate layer of class II composite restoration.

Materials and methods

Thirty human maxillary premolars were selected and divided into three groups. In groups I, II, and III, class II cavities were prepared. Groups I and II were restored with 2 mm and 4 mm thickness of SRFC as intermediate layer. Group III as control group was restored with nanohybrid composite. Thermocycling procedure was performed manually 250 times. Fracture resistance was measured by using Universal Testing Machine. Data were analyzed statistically using One-way Analysis of Variance (ANOVA) and post hoc least significant difference (LSD) test.

Results

The result showed that group II had the highest fracture resistance and group III had the lowest fracture resistance. The difference between groups was statistically significant (p value < 0.05).

Conclusion

The conclusion showed that adding 4 mm of SFRC as an intermediate layer increased the fracture resistance.

Clinical significance

The use of SFRC as intermediate layer enhanced the fracture resistance of class II composite restoration.

A sala de aula e estratégias de ensino-aprendizagem têm sido debatidos como forma de explorar a importância dos processos de educação na construção da realidade. Assim, este artigo objetiva verificar a relação entre a percepção de prática docente de professores de cursos superiores de Administração e as concepções de liderança expressas em sala de aula. Com abordagem qualitativa, entrevistou-se quatorze professores de Universidades de Santa Catarina. Os resultados demonstraram as expressões de liderança nas práticas docentes de cada docente, quando consideradas suas dimensões: universidade, aluno, regulação, professor e processo educativo. Em geral, os professores consideram a universidade local ideal para educação, seus alunos precisam ser sujeitos dos processos de ensino e a lei tem impacto positivo em suas práticas. Os docentes consideram que seus papéis sejam de transmissores dos conteúdos e autoridades em sala; assim escolhem a aula expositiva e dialogada como estratégia. Quando relacionada ‘prática docente’ com as abordagens da liderança concluiu-se que, embora expressem liderança em suas práticas, não é possível delimitar seus comportamentos a uma única concepção de liderança.

O objetivo deste estudo foi desenvolver uma teoria substantiva sobre os desdobramentos da regulação no contexto de uma Universidade Comunitária Catarinense que aderiu ao PROIES. Para isso, sob a ótica de Strauss e Corbin (2008), utilizou-se a estratégia metodológica da Grounded Theory, considerando as entrevistas e as análises documentais como técnicas de coleta de dados e os gestores do processo de adesão, como sujeitos da pesquisa. Os resultados relevaram seis elementos um conjunto de categorias, propriedades e dimensões que contribuem para explicar o fenômeno que, integradas a hipótese fundamental da teoria, contribuem para o desenho de um esquema teórico que sustentam o processo em investigação. As conclusões do estudo mostram que a adesão ao PROIES proporcionou o desenvolvimento de novas competências institucionais, traduzidas em novos processos e novos comportamentos nas pessoas, materializadas em um conjunto de conhecimentos, habilidades e atitudes, consideradas, portanto, como os principais desdobramentos da regulação no contexto em estudo.

Objetivo: Determinar la relación entre el estilo de vida y el estado nutricional de adultos que mantienen una alimentación y comportamiento basado en su convicción o credo. Material y Métodos: Fue una investigación de tipo aplicada no experimental, con nivel descriptivo, transversal, y diseño transeccional correlacional, con un tamaño de muestra de 190 participantes. Se aplicó un cuestionario de estilo de vida y los datos del estado nutricional se obtuvieron mediante medidas antropométricas (peso, talla y circunferencia de cintura) y bioimpedancia (grasa corporal y visceral). Resultados: Se encontró que el estilo de vida fue saludable en 65,8% y el estado nutricional deficiente en el 58,4% de los participantes. El Índice de masa corporal es normal en el 48,4% (25,9±3,6) y su relación es estadísticamente significativa con el estilo de vida (p=0,023); la circunferencia de cintura resultó normal en el 43,2% (86,3±10,0), no encontrándose una relación significativa con el estilo de vida (p=0,221); la grasa corporal resultó normal en el 28,4% (35,1±7,4) y su relación con el estilo de vida fue significativa (p=0,000); mientras, la grasa visceral obtuvo un óptimo en el 80% de los participantes (8,0±2,9) y no presentó relación significativa con el estilo de vida (p=0,178). Conclusión: Se encontró una relación significativa (p=0,004) entre el estilo de vida y el estado nutricional, concluyendo que el estado nutricional de los adultos participantes es afectado por su creencia.
