Published: June 2021

Learning models that are not precise have an impact on low student understanding so that the student completeness score is still below 50%, so appropriate action is needed to improve the quality of learning so that students' understanding in learning mathematics increases. The purpose of this study was to determine the increase in mathematical understanding of students by using cooperative learning model type Snawbal throwing. This type of research is classroom action research through 3 cycles. The increase in learning outcomes is determined based on an increase in the average understanding of students, the attainment of absorption and learning completeness. Increment refers to the ratio between the value of cycle I, cycle II and cycle III. The results showed that the implementation of the snowball throwing type of cooperative learning model could improve students' mathematical understanding of set material. It can be seen from the students' average understanding of mathematics increased from 75 (cycle I) to 9 (cycle II), and 82 (cycle III). The increase also occurred in the attainment of absorption and learning completeness. The absorption capacity increased from 50% to 70% and 73%. The learning completeness has increased from 50% to 70% and 73%.
Comments about the relationship between Science and Faith in the Magisterium of the Church
Authors: Parra Contreras Reyber Antonio
Published: June 2021

The text analyzes the relationship between Science and Faith in the Magisterium of the Catholic Church. The analysis is based on the position of the Vatican Councils I and II about the importance of Faith and Reason for man, in his search for truth; simultaneously, the orientations of popes Leo XIII and John Paul II were taken into account, in their Encyclicals Aeterni Patris and Fides et Ratio, respectively; some speeches by Popes Paul VI, Benedict XVI and Francis before the Pontifical Academy of Sciences were also analyzed. The Church has sought - from the First Vatican Council to the present - to bring, harmonize and complement the relationship between Faith and Reason; its interest is not limited to promoting scientific research; it also aspires that knowledge be ordered to the welfare of the human being, and the horizon of faith is recognized in the search for truth.
An Observational Study of a “Rosetta Stone” Solar Eruption
Authors: Mason E. I. , Antiochos Spiro K. , Vourlidas Angelos
Published: June 2021

This Letter reports observations of an event that connects all major classes of solar eruptions: those that erupt fully into the heliosphere versus those that fail and are confined to the Sun, and those that eject new flux into the heliosphere, in the form of a flux rope, versus those that eject only new plasma in the form of a jet. The event originated in a filament channel overlying a circular polarity inversion line and occurred on 2016 March 13 during the extended decay phase of the active region designated NOAA 12488/12501. The event was especially well observed by multiple spacecraft and exhibited the well-studied null-point topology. We analyze all aspects of the eruption using Solar Dynamics Observatory Atmospheric Imaging Assembly and Helioseismic and Magnetic Imager, Solar-Terrestrial Relations Observatory Extreme Ultraviolet Imager, and Solar and Heliospheric Observatory Large Angle and Spectrometric Coronagraph (SOHO LASCO) imagery. One section of the filament undergoes a classic failed eruption with cool plasma subsequently draining onto the section that did not erupt, but a complex structured coronal mass ejection/jet is clearly observed by SOHO/LASCO C2 shortly after the failed filament eruption. We describe in detail the slow buildup to eruption, the lack of an obvious trigger, and the immediate reappearance of the filament after the event. The unique mixture of major eruption properties observed during this event places severe constraints on the structure of the filament channel field and, consequently, on the possible eruption mechanism.

Authors: Kurniawan Albert , Lainama Maria Steffany , Diarsvitri Wienta
Published: June 2021

BACKGROUND: The occurrence of febrile seizure is affected by numerous factors, but some studies indicated that inflammatory cytokines might contribute to the development of febrile seizure. In resource limited settings, complete blood count (CBC) might serve as potential indices for inflammatory response.

AIM: The aim of the present study was to determine the role of mean platelet ratio and neutrophil to lymphocyte ratio (NLR) on the risk of febrile seizures in children aged 6–24 months and 25–59 months at S.K. Lerik Regional Public Hospital in Kupang City, East Nusa Tenggara, Indonesia.

METHODS: A case-control study was carried out in 104 patients (52 in the case group and 52 in the control group) aged 6–59 months. The CBC tests were taken on the first visit in the emergency room at S.K. Lerik Regional Public Hospital.

RESULTS: Our study found that the odds for experiencing febrile seizure in younger children aged 6–24 months were 3.281 (95% confidence interval 1.470, 7.324) times as large as the odds for older children aged 25–59 months. There was a significant but weak correlation between the types of febrile seizure or fever and age of children (r = 0.279; p = 0.012).

CONCLUSIONS: Children aged 6–24 months had higher risk of developing febrile seizure, compared to children aged 25–59 months. Further, for each unit decrease in NLR, we expected a 0.883 decrease in the odds for febrile seizures in the case group, compared to control group.

Authors: Alagha Ebaa , Alagha Mustafa Ibrahim
Published: June 2021

AIM: This study compared the impact of two resin infiltration systems on microhardness of demineralized enamel before and after an acidic challenge.

MATERIALS AND METHODS: A total of forty human maxillary molar teeth were used in this study. Each tooth has 4 groups (four standardized windows onto each tooth). Group A1: Untreated sound enamel surface (positive control), Group A2: Artificially demineralized enamel surface (negative control), Group A3: Icon resin infiltrating to demineralized enamel, while Group A4: Single bond universal adhesive applied to the demineralized enamel surface. All teeth were immersed in a demineralizing solution. The groups (A3 and A4) were further subdivided into two subgroups according to acidic ethanol challenge Subgroup B1: Specimens tested before an acidic challenge and B2: Specimens tested after an acidic challenge. Vickers microhardness test was done for all groups. One-way analysis of variance (ANOVA) was used to study the difference between tested groups on mean microhardness within each group. Tukey’s post-hoc test was used for pair-wise comparison between the means when ANOVA test was performed, and the significance level was set at p ≤ 0.05.

RESULTS: Icon resin infiltration and single bond universal adhesive showed significantly higher mean microhardness than negative control, but significantly lower mean microhardness than positive control. However, insignificant difference was found between icon and single bond universal adhesive. After the acidic challenge, icon resin infiltration showed significantly higher mean microhardness than negative control. However, single bond universal adhesive showed insignificant difference as compared to the negative control.

CONCLUSION: After an acidic challenge, icon resin infiltration was more successful than single bond universal total-etch adhesive system in microhardness.

RECOMMENDATION: Icon resin infiltration technique is a promising, noninvasive approach that prevents the progress of the carious lesion.
A Seven-year Follow-up Study of Patient Satisfaction with Three-implant-retained Mandibular Overdentures
Authors: ElGabry Hisham Samir
Published: June 2021

PURPOSE: This study aimed to compare patients’ satisfaction with mandibular overdentures retained by three-splinted implants versus conventional complete denture wearers during a 7-year follow-up study period.

MATERIALS AND METHODS: Thirty edentulous male patients (mean age: 60 years) were carefully selected and divided into two equal groups. All patients received a new set of complete dentures. Group I patients received three implants in the anterior mandible and were connected after 3 months with bars, clips, and loaded. Group II patients received conventional complete dentures. Patients’ satisfaction was recorded for both groups at 3 weeks (baseline) and after 1, 3, 5, and 7 years. Patients were then asked to grade their overdentures/dentures on a visual analog scale and written questionnaire to evaluate their overall satisfaction.

RESULTS: Satisfaction scores of Group I patients were found to be statistically significantly higher than that of Group II patients (p < 0.05) at 3, 5, and 7 years follow-up, meanwhile, no statistically significant difference was found at baseline or after 12 months.

CONCLUSION: The long-term results suggest that three-implant-retained mandibular overdenture with a clip-bar attachment appears to be a successful rehabilitation strategy which is superior to conventional dentures for patients with advanced ridge resorption.

Published: June 2021

BACKGROUND: Atherosclerosis causes acute myocardial necrosis and inflammation characterized by increased mean platelet volume (MPV) and serum amyloid A (SAA). Creatine Kinase Myocardial Band (CKMB) is known as myocardial necrosis marker commonly used in daily practice to help diagnosing acute coronary syndrome.

AIM: The purpose of this study was to determine the correlation between MPV, SAA, and CKMB in patients with acute coronary syndrome.

METHODS: An analytic observational study with a cross-sectional approach was conducted from May to July 2019. This study involved 32 patients with ACS at the Emergency Department of Dr Kariadi Public Hospital. The inclusion criteria of this study were patients with chest pain, aged 30–75 years, and normal body temperature while the exclusion criteria were malignancy, undergoing chemotherapy/radiation, renal failure, hypertension, and liver disease. Examination of CKMB was done using the spectrophotometry method, MPV value was measured using a hematology analyzer, and SAA level was measured using the ELISA method. Statistical test was done using Spearman correlation.

RESULTS: The median (min-max) of MPV and SAA values was 9.85 (2.78-11.7) fL and 40.454 (5.879–66.059) μg/ml, while the mean ± SD (min-max) value of CKMB was 115.47 ± 155.97 (10–608) U/L. The correlation coefficient between CKMB level with MPV and SAA levels were r = −0.244 (p = 0.179) and r = 0.442 (p = 0.011), respectively.

CONCLUSION: There was a significant positive moderate correlation between CKMB and SAA levels which could be used as a marker of acute inflammation in ACS, whereas inflammatory marker of MPV did not have a significant correlation.

Published: June 2021

BACKGROUND: Ichthyosis vulgaris is the most common type of Mendelian disorders of cornification, caused by loss-of-function mutations in the gene encoding epidermal protein filaggrin (FLG), namely R501X and 2282del4. FLG 2282del4 mutation in heterozygotes is incompletely penetrant. Polymorphisms in one-carbon metabolism genes could be associated with clinical manifestation of ichthyosis vulgaris. AIM: The purpose of the present study was to analyze the effects of MTHFR, MTR and MTRR polymorphisms in patients with ichthyosis vulgaris. METHODS: 31 patients with ichthyosis vulgaris, 7 their FLG heterozygous relatives without symptoms of disorder, and 150 healthy controls were enrolled in study. FLG null mutations —R501X (rs61816761) and 2282del4 (rs558269137) — and one-carbon metabolism gene polymorphisms — MTHFR C677T (rs1801133), MTHFR A1298C (rs1801131), MTR A2756G (rs1805087) and MTRR A66G (rs1801394) — were analyzed by a polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) assay. RESULTS: Among patients with ichthyosis, heterozygous for FLG 2282del4 mutation, the distributions of genotypes for folate metabolism genes were: MTHFR C677T CC:CT:TT —29.4%:70.6%:0.0%; MTHFR A1298C AA:AC:CC — 52.9%:47.1%:0.0%; MTR A2756G AA:AG:GG — 70.3%:23.5%:5.9%; MTRR A66G AA:AG:GG — 23.4%:52.9%:23.5%. The frequencies of MTR 2756AA and MTRR 66GG genotypes were 1.4–1.6 times higher in affected individuals heterozygous for 2282del4 than in patients with other FLG genotypes. In affected 2282del4 heterozygotes, the frequency of MTR 2756AA genotype was 1.6 times greater than in healthy controls (p<0.01). The strongest association was found between MTHFR 677CT/MTHFR 1298AA/MTR 2756AA/MTRR 66AG genotype and ichthyosis — OR=11.23 (95% CI 2.51−50.21, p=0.002). CONCLUSIONS: Various genotypes of one-carbon metabolism genes increase the risk of ichthyosis in heterozygotes for the FLG 2282del4 mutation (OR 2.799‑11.231). The most probable predisposing genotype is 677CT/1298AA/2756AA+AG/66AG.
De novo Stage IV Luminal Breast Cancer: Yes or No for Local Treatment? Serial Cases and Review
Authors: Karakolevska-Ilova Marija , Simeonovska Joveva Elena , Serafimov Aleksandar
Published: June 2021

BACKGROUND: Primary stage IV breast cancer accounts about of 3–5% of newly diagnosed breast cancer cases. The management of this patient subset mostly comprises systemic therapy, with additional surgery or radiotherapy to control locoregional symptoms. Some of the retrospective studies showed the benefit of locoregional treatment as the first treatment of choice for overall survival (OS), but the efficacy of primary site surgery remains controversial for OS in prospective, controlled trials.

AIM: We aimed to presents series of cases with primary metastatic breast cancer with diffuse bone metastasis.

MATERIALS AND METHODS: This study was serial of cases with primary metastatic breast cancer with diffuse bone metastasis and a review of the literature. All of the cases were treated with upfront surgical resection of the primary in the breast.

RESULTS: During the follow-up period of 36 months, all of our patients were still alive.

CONCLUSION: Retrospective studies about resection of primary tumor as the first treatment of choice are with conflicting results, which may be related to randomization bias, including different biological types of breast cancer, different metastatic sites, and patients with different menopausal status. On the other hand, prospective studies did not show any powerful results that would lead the treatment in de novo stage IV breast cancer because of few limitations such a short follow-up period (between 23 and 40 months), younger patients, ER-positive/HER2 negative tumors, and type of chemotherapy given or not upfront. The effect of upfront surgery in newly metastatic breast cancer patients is still challenging, so there is a need to identify the exact cohort of patients who could benefit from surgery.

Published: June 2021

BACKGROUND: Aortic graft infection is one of the most serious complications of vascular reconstruction with the incidence of 1%. The clinical presentation can vary, which delays the diagnosis.

CASE REPORTS: Infections in our patients affected iliac, inguinal region, and retroperitoneum, which are not relatively common sites of graft infection. We present clinical presentation, imaging procedures, and surgical treatment of three patients with unknown cause of late graft infection after 6, 7, and 9 years.

CONCLUSION: In our presentations, the etiological factors of the infection are not known, but they suggest that events in the gastrointestinal tract may be related to them. Aggressive surgery should be taken into consideration as a first choice in the similar cases.

Estructura familiar, deterioro del mercado laboral y desigualdad en España para el período 2008-2017
Authors: Pérez Corral Antonio Luis , Moreno Mínguez Almudena
Published: June 2021

En este artículo se estudia cómo el deterioro del mercado de trabajo español, a raíz de la crisis económica del año 2008, ha repercutido en la desigualdad laboral y económica de los hogares según la estructura familiar. Para ello, a partir de los datos de la Encuesta de Condiciones de Vida, comparamos la situación de los hogares monoparentales y biparentales en términos de intensidad laboral y bajos ingresos por trabajo. Los principales resultados muestran que, en relación con la intensidad laboral, tanto en el periodo de crisis económica como en el posterior de recuperación ha disminuido la ventaja que las familias monoparentales presentaban con respecto a la biparentales. Por otro lado, aunque los hogares monoparentales registran una mayor probabilidad de experimentar pobreza de ingresos laborales, la diferencia con los hogares biparentales no ha variado a lo largo del periodo de estudio.
EFFECT OF PHYSICAL ACTIVITIES ON HEART RATE VARIABILITY AND SKIN CONDUCTANCE
Authors: Soni Ankita , Rawal Kirti
Published: June 2021

The sympathetic and parasympathetic function of the Autonomic Nervous System (ANS) is the primary cause of the variations in Heart Rate and Skin Conductance (SC) during different physical activities.

This paper aims to analyze the effect of different physical activities i.e. (a) Supine (b) Standing and (c) Warm-up, on Heart Rate Variability (HRV) and SC. The standard dataset of 18 subjects has been used to analyze the effect of physical activities on the HRV and SC. In the used dataset, the subjects are in supine, standing, and warm-up positions. The linear methods (time domain & frequency domain) of HRV are implemented on the standard dataset for analyzing the effect of physical activities. It has been observed with the analysis of the HRV that the mean value of time domain methods i.e. the NN interval’s standard deviation (SDNN), the successive RR interval’s root mean square (RMSSD), RR intervals with more than 50 ms differences in between them (NN50), percentage of successive RR intervals that have the difference of more than 50 ms (pNN50) are decreased and the value of Heart rate (HR) increased when the activity has been changed from supine to standing and standing to the warm-up positions. The value of frequency domain methods, such as low frequency (LF) and the ratio of low and high frequency (LF/HF) increased, while the value of HF decreases as activity changes from supine to standing and from supine to warm-up position. Further, the increment is also observed in the value of SC when activity is switched from supine to standing and from standing to the warm-up position. It is concluded from the results that there is a significant decrement that is observed in the value of HRV, while the increment is observed in the value of SC and HR. Decrement of HRV reflects that the sympathetic activity is increased as activity changed from supine to standing and further from standing to warm-up positions.

Authors: Handa Anand , Agarwal Rashi , Kohli Narendra
Published: June 2021

Due to the highly variant face geometry and appearances, Facial Expression Recognition (FER) is still a challenging problem. CNN can characterize 2-D signals. Therefore, for emotion recognition in a video, the authors propose a feature selection model in AlexNet architecture to extract and filter facial features automatically. Similarly, for emotion recognition in audio, the authors use a deep LSTM-RNN. Finally, they propose a probabilistic model for the fusion of audio and visual models using facial features and speech of a subject. The model combines all the extracted features and use them to train the linear SVM (Support Vector Machine) classifiers. The proposed model outperforms the other existing models and achieves state-of-the-art performance for audio, visual and fusion models. The model classifies the seven known facial expressions, namely anger, happy, surprise, fear, disgust, sad, and neutral on the eNTERFACE’05 dataset with an overall accuracy of 76.61%.

Lipiodol lymphangiography as a treatment for refractory postoperative chylothorax: a case report
Authors: Lamine Nesrine , Agrafiotis Apostolos C. , Lardinois Ines
Published: June 2021

Postoperative chylothorax is the most frequent cause of traumatic thoracic chyle leakage. Conservative treatment is primarily used to treat low flow rate chylothoraces and should be initiated as soon as the diagnosis has been made. In case of high flow rate chylothorax or failure of initial treatment, surgery and radiological treatment are indicated. Despite this fact, there is a lack of consensus regarding the best therapeutic option to choose. In the case reported herein, a postoperative chylothorax with a low flow chyle leakage which didn’t respond to conservative treatment is demonstrated. We used lipiodol lymphangiography to determine the site of chyle leakage and to successfully treat our patient. Risk factors for non-response to conservative treatment are also discussed.
Recurrent aplastic anemia with donor-type aplasia
Authors: Majumder A , Misra S , Kumar V
Published: June 2021

Donor-type aplasia (DTA) is a condition where an individual continues to be aplastic even after a successful engraftment of a hematopoeitic stem cell transplant with a majority of donor type cells in the bone marrow. This entity has been seen with varying frequency around the world, especially in Southeast Asia. However, its incidence in the Indian subcontinent remains fairly low. Here is a case of a 17-year-old child with DTA who had a 89% population of donor cells after a successful transplant and presented with recurrent severe aplastic anemia later. The patient eventually succumbed to his condition before a second transplant could be performed. The awareness about the seriousness of this relatively rare condition, therefore, needs to be emphasized.

is of type-

I

, then the rescaled flow at the first finite singular time converges smoothly to a self-shrinker flow with multiplicity one. This result confirms Ilmanen's multiplicity-one conjecture under the assumption that the mean curvature is of type-

Published: June 2021

Background: Isolated sphenoid sinus disease (ISSD) is rare. Fungus ball (FB) is the third most common ISSD. We analysed the characteristics of isolated sphenoid FB based on demographic data, presenting symptoms, preoperative computed tomography (CT), magnetic resonance imaging (MRI), and treatment outcomes. Methodology: From 1999 to 2012, 29 patients were identified with isolated sphenoid FB. Demographic data; clinical characteristics; endoscopic, CT, and MRI findings and treatment outcomes were retrospectively analysed. Results: The most common symptom was headaches, which were localized in various regions of the brain. Other symptoms were uncommon. The most common CT findings were sclerosis, calcification, enlarged sinus and total opacification. On T2-weighted MRI images, we most commonly observed signal void. Endoscopic transnasal paraseptal sphenoidotomy was performed in all patients, and for most, this was performed under local anaesthesia. No recurrence was observed in any patient. Conclusion: Isolated sphenoid FB is predominantly observed in older women, and it is characterised by headaches and sclerosis of the sinus wall observed on CT scans. In cases of isolated sphenoid FB, endoscopic transnasal paraseptal sphenoidotomy can be successfully performed under local anaesthesia, which may facilitate rapid recovery and a low morbidity rate.

Background: The paranasal sinuses can be a bacterial reservoir for pulmonary infections in patients with cystic fibrosis (CF) METHODOLOGY: In this prospective, non-randomised, uncontrolled, intervention cohort study, the clinical effect of sinus surgery followed by two weeks` intravenous antibiotics, 6 months` antibiotic nasal irrigations was assessed in 106 CF patients. Results: One year after sinus surgery, the prevalence of intermittently colonised patients had decreased by 38%, while the prevalence of non-colonised patients had increased by 150%. The frequency of pulmonary samples with CF pathogens was reduced after surgery. Specific IgG against P. aeruginosa decreased after six months. Additionally, the self reported symptoms of chronic rhinosinusitis and quality of life improved. Conclusion: Combined sinus surgery and postoperative systemic and topical antibiotic treatment significantly reduced the frequency of pulmonary samples positive for CF pathogens in the first year after sinus surgery.

This study aimed at investigating the guests’ experience dimensions and their effects on destination marketing bottom lines of satisfaction and revisit intention. This is borne of the overarching importance of customer experience (CX) which has been acknowledged by scholars and practitioners and understanding of the concept been sought from various sectoral perspectives. Admittedly, experience-based investigations in the hotel service sector have been scarce, particularly from a non-western context. The study utilised an intercept approach to collect data from 400 hotel guests in a city in Southern Nigeria. The research model and the formulated hypotheses were tested using partial least square structural equation model (PLS-SEM) with the aid of SmartPLS software. The study findings reveal that guest experience dimensions (utilitarian, hedonic and relational) have a positive and significant influence on guests’ revisit intention and satisfaction with the exception of hedonic experience whose relationship with satisfaction was statistically insignificant. Overall, the research model explained 56.5 per cent of the variance in guest satisfaction and 68.7 per cent on guest revisit intention. This study adds an empirically supported strategic direction for proper guest experience management in hotels from a non-western context.

Description: The COVID-19 pandemic compelled the traditional higher educational institutions to make a quick transition to the virtual instruction model. Considering the COVID-19 restrictions, the Department of Clinical Pharmacy and Pharmacology at Ras Al Khaimah College of Pharmaceutical Sciences, United Arab Emirates restructured their original onsite experiential training for final year Bachelor of Pharmacy students as a virtual online experience to ensure educational continuity.  
Evaluation: The virtual experiential training was conducted over two weeks and was imparted employing different virtual platforms like Google Classroom, Google Meet, Google Forms, Google Docs, etc. As a part of the community pharmacy training, the students were given different e-activities and tasks like e-case scenario analysis and interpretation, e-prescription screening, virtual patient education and were shown various 3-D animated videos related to community pharmacy. For the hospital training, the students were given different e-cases for developing pharmaceutical care plans, e-case scenario analysis, e-drug information query and were shown different animated videos related to rounds of different hospital departments.   
Conclusion: The virtual experiential training was successfully conducted achieving the desired learning outcomes and was well received by the students. Based on this experience, it is recommended that efforts should be made to develop an integrated model for experiential training in the future, which can be an amalgamation of online tools and traditional experiential methods.

Availability of Some Tropical Plants as Alternative Roughage Source in Ruminant Feeding
Authors: GBAGUIDI Gbetolossi , SARIÇİÇEK Zehra
Published: June 2021

Roughages have vital importance in the diet of ruminants because they are cheap and absolutely necessary for digestive physiology. Ruminant nutrition requires quality feeds to obtain high amounts of product. As more than half of the business inputs are made up of feed expenses, the necessity of high-quality roughage sources, which are cheaper compared to concentrate, arises. The high quality of roughage means that the amount of mixed feed that can be put into the ruminant ration to meet the nutrient requirement is less. Thus, the cost of the product to be obtained will decrease and the net profit will increase. Since the leaves of some plants grown in the tropical region and the fruits and shells that cannot be used as human food are not utilized, they cause environmental pollution, and the feed cost cannot be reduced because the vegetable waste is not used in animal feeding. Many tropical plant leaves and waste are rich in protein and crude fiber. Crude protein levels in the leaves of some tropical plants can be up to 30%. The usability of tropical plant leaves and fruit peels, which are rich in nutrients, as roughage has not been adequately studied. These plants can be used as an alternative roughage source for ruminants in times of shortage of quality roughage and in times of famine, increasing animal production and preventing problems in the environment. The purpose of this review is to examine the possibilities of using leaves and fruits and wastes of some tropical plants (Guava, papaya, banana, mango, pineapple, cassava, moringa and avocado) as an alternative roughage source in ruminants.

Published: June 2021

Esse artigo é fruto de uma pesquisa que investigou, a partir das perspectivas de estudantes de licenciaturas de uma Universidade Federal mineira, como o vídeo tem sido utilizado enquanto recurso didático na formação docente. Partimos do princípio que o vídeo consiste em um recurso que pode despertar a criatividade, o interesse e favorecer diferentes dimensões cognitivas de estudantes em contextos educacionais diversos, podendo vir a assumir um papel relevante nos processos de ensino e aprendizagem. Para fins de produção de dados, foram realizadas entrevistas semiestruturadas com grupos de estudantes dos cursos de licenciatura em Pedagogia, História e Letras, visando identificar as visões desses futuros professores em relação ao uso de recursos audiovisuais na sua formação docente. Como resultados, obtivemos que os estudantes entendem que este tipo de tecnologia digital pode potencializar a aprendizagem, porém não se reconhecem totalmente preparados para utilizá-la na futura prática como docentes e sentem falta de uma formação específica que aborde sobre a produção e a utilização dessa tecnologia no ensino. Assim, esse estudo se mostrou importante, uma vez que ofereceu elementos que contribuem com o debate atual acerca do uso do vídeo e das tecnologias digitais, em geral, na Educação.
A model for Enhancing Academic Staff Promotion System in Vocational and Technical Education: College of Technological Studies, As A Case Kuwait
Authors: Al-Ali Salah
Published: June 2021

Vocational and technical colleges and schools is a type of education which place students on apprenticeship system. It is through which students can spend certain time in industry premises to gain the necessary skills and attitudes mostly required by industries. Vocational and technical education is completely different from a formal education that is taught in classrooms. Developing countries (e.g., Kuwait, Oman, Qatar), has realized the importance of vocational and technical education in vital sectors of the economy (e.g., oil, electricity and water, construction), where expatriates are the dominate workforce and the need to reduce dependence on expatriates is one of high governments manpower strategy. In Kuwait, the government has absorbed the need to reduce dependence on expatriates and thus established the College of Technological Studies, CTS, to respond to the urgent need of skilled and semi-skilled indigenous workforce. Thus, the management of the College of Technological Studies has to apricate and value the significant role of the College of Technological Studies in meeting government workforce objectives. This can be accomplished by ensuring that academic staff has the necessary skills to prepare students to meet industrial needs and ambitious. The academic staff promotion system must be one of the CTS management priorities. The constant review and update the academic staff promotion system is crucial to maintain high standard of vocational and technical graduates. A model is introduced in this research for academic staff promotion system that enable the CTS management to review and assess the quality of the CTS academic staff competencies and their ability in meeting industrial requirements. The new model for academic staff promotion system would overcome and/or reduce the deficiencies of the current academic staff promotion system. The new model would encompass more realistic and efficient criteria’s for assessing the performance of vocational and technical academic staff and introduce a proper work methodology and procedure for minimizing the percentage of errors while promoting a candidate to a higher academic status.
