FLETTNER ROTORS PERFORMANCE AND INTERACTION EFFECTS ON THE MARIN HYBRID TRANSITION COASTER
Authors: Garenaux M , Schot J J A
Published: October 2022

In the context of ship design, including wind propulsion, knowing the aerodynamic performance of a ship and its wind propulsors is essential. In the literature, the performance of wind propulsors is generally derived from wind tunnel test data, full scale tests or CFD. Those experimental or numerical databases are often omitting the interactions with the ship and its superstructures and atmospheric boundary layer. In this research, a numerical approach using RANS simulations is developed to estimate the effects of the interaction between the MARIN Hybrid Transition Coaster (MHTC) and its three Flettner rotors. In order to assess the effects of these interactions, the performance of a Flettner rotor positioned on the deck of the vessel is compared to the performance of a free standing Flettner rotor. Large interaction effects are found to depend on the apparent wind angle. Accounting for these interactions is essential. A model is proposed to correct the performance of a free standing Flettner rotor to the performance of a rotor on the deck of the vessel. In addition the effects of multiple wind propulsors are studied in relation to this model.

How relevant are socio-economic-demographic factors for the South African marketer?
Authors: Simpson John
Published: October 2022

In hierdie artikel ondersoek die skrywer die toepaslikheid daarvan om sosio-ekonomies-demografiese (SED) veranderlikes te gebruik as basis vir marksegmentasie in Suid-Afrika. Uit die literatuur blyk dit dat hierdie benadering sekere tekortkominge het; desondanks maak talle bemarkers steeds daarvan gebruik en dan met groot sukses. Die skrywer oorweeg die kritiek wat teen die gebruik van SED-veranderlikes gemik is en kom dan tot die gevolgtrekking dat, tot tyd-en-wyl die nuwere, akademies meer modieuse tegnieke soos psigografika empiriese geldigheid verwerf het, die Suid-Afrikaanse bemarker wys sal wees om voort te gaan om die SED-benadering te gebruik, miskien tesame met ander tegnieke, om sy mark te segmenteer.

Enhanced recovery after surgery (ERAS) measures have not been systematically applied in transurethral surgery for benign prostatic hyperplasia (BPH). This study was performed on patients with BPH who required surgical intervention. From July 2019 to June 2020, the ERAS program was applied to 248 patients, and the conventional program was applied to 238 patients. After 1 year of follow-up, the differences between the ERAS group and the conventional group were evaluated. The ERAS group had a shorter time of urinary catheterization compared with the conventional group (mean ± standard deviation [s.d.]: 1.0 ± 0.4 days vs 2.7 ± 0.8 days, P < 0.01), and the pain (mean ± s.d.) was significantly reduced through postoperative hospitalization days (PODs) 0–2 (POD 0: 1.7 ± 0.8 vs 2.4 ± 1.0, P < 0.01; POD 1: 1.6 ± 0.9 vs 3.5 ± 1.3, P < 0.01; POD 2: 1.2 ± 0.7 vs 3.0 ± 1.3, P < 0.01). No statistically significant difference was found in the rate of postoperative complications, such as postoperative bleeding (P = 0.79), urinary retention (P = 0.40), fever (P = 0.55), and readmission (P = 0.71). The hospitalization cost of the ERAS group was similar to that of the conventional group (mean ± s.d.: 16 927.8 ± 5808.1 Chinese Yuan [CNY] vs 17 044.1 ± 5830.7 CNY, P =0.85). The International Prostate Symptom Scores (IPSS) and quality of life (QoL) scores in the two groups were also similar when compared at 1 month, 3 months, 6 months, and 12 months after discharge. The ERAS program we conducted was safe, repeatable, and efficient. In conclusion, patients undergoing the ERAS program experienced less postoperative stress than those undergoing the conventional program.

Authors: Kopeya Abdelrahman Elsayed , Elshamy Ahmed A. , Moussa Mahmoud Abdelhady
Published: October 2022

Background and aim

Many complications have been recorded after hypospadias repair surgeries. The most common one is the urethrocutaneous fistula (UCF). In this study, we aimed to compare the closure outcome of the small-sized and medium-sized UCF after hypospadias repair with and without autologs platelet-rich plasma (PRP) graft.

Patients and methods

This is a prospective comparative study for managing UCF in the pediatric age group of over 1 year. They were randomly divided into two groups: group A included 20 patients who underwent repair without PRP and group B included 20 patients who underwent repair with PRP. Complication rates were compared between the two groups.

Results

There was a significant difference in the occurrence of complications between the two groups. Recurrence of the fistula was observed in five cases, three (15%) in group A and two (10%) in group B. In group A, the three cases with fistula failed to be treated conservatively and needed another operation 6 months after the primary repair, while in group B, two cases were treated conservatively, and spontaneous closure of the fistula occurred while only one case required another operation for closure of the fistula. Postoperative infection was reported in two (10%) cases in group A and three (15%) cases in group B; they were treated using topical and systemic antibiotics. An extensive scar was reported in one case in group A.

Conclusion

Autologs PRP graft could be used in hypospadias surgeries and the repair of post-hypospadias repair UCF as it is safe, easily applicable, and proven its role in decreasing complications.

Published: October 2022

Background and aim

Chronic rhinosinusitis (CRS) is an upper respiratory-tract disease, which affects general health of patients. This study aims to detect Helicobacter pylori in paranasal sinus specimens of patients having CRS and to approve if there is a relation between H. pylori and CRS.

Patients and methods

This study included 60 patients complaining of nasal and gastroesophageal reflux disease (GERD) symptoms. According to computed tomography findings, patients were divided into group A: this included 30 patients, they had chronic sinusitis, or nasal polyp and GERD symptoms, and group B: this included 30 patients, they had inferior-turbinate hypertrophy without sinus affection and with GERD symptoms. All patients were submitted to endoscopic surgery, under general anesthesia, and the samples of diseased sinus mucosa or nasal polyp in group A and the samples of inferior turbinate in group B were sent for histopathological and microbiological examination.

Results

In group A, rapid urease test (RUT) was positive in 10 (33.3%) patients and negative in 20 (66.6%) patients, while immunohistochemistry (IHC) was positive in five (16.5%) patients and negative in 25 (83.5%) patients. In group B, RUT was positive in five (16.5%) patients and negative in 25 (83.5%) patients, while IHC was positive in 0 (0%) patients and negative in 30 (100%) patients.

There was a significant difference between RUT and IHC results in both groups (P=0.032).

Conclusion

H. pylori infection has possible role in chronic sinusitis. More studies are required to confirm this correlation.

Authors: Yousef Hassan S. , Salih Mohamed A. , Sayed Shimaa B.
Published: October 2022

Background and aim

Collagen cross-linking (CXL) is the available treatment to arrest the progression of keratoconus (KC). It consists of photopolymerization of collagen induced by combined action of a photosensitizing substance, and ultraviolet-A light.

The aim of the study is to assess higher-order aberrations (HOAs) of cornea in patients with early KC before and after cross-linking using the Bausch & Lomb Zywave II aberrometer.

Patients and methods

In total, 30 patients (nine males and 21 females), aged 19–35-years old with mild KC. HOAs examination was done using Zywave device before and after corneal CXL and followed up 1, 3, and 6 months postoperative.

Results

Preoperative and postoperative 1-month Root Mean Square (RMS) of the total HOA differences was statistically insignificant with P value of 0.102, however, preoperative and postoperative 3 and 6 months showed higher significance with P value of 0.007 and P value less than 0.001, respectively. Preoperative and postoperative 1-month RMS of total coma-order aberration differences was statistically insignificant (P=0.211), however preoperative and postoperative 3 and 6 months showed higher significance with P value of 0.024 and value less than 0.001, respectively. Preoperative and postoperative 1- and 3-month secondary astigmatism-aberration differences were statistically insignificant (P=0.070 and 0.216, respectively), however preoperative and postoperative 6 months showed higher significance with P value less than 0.001.

Conclusion

There is reduction in the parameters of HOAs after CXL in patients with KC, especially total HOA, coma, and secondary astigmatism aberrations.
Course and outcome of bipolar I disorder among Indian patients: A retrospective life-chart study
Authors: Dhiman Shallu , Subodh BN , Chakrabarti Subho
Published: October 2022

Background:

Indian studies on the course and outcome of bipolar disorder (BD) are scarce and their methodologies vary. Nevertheless, differences from Western ones have been noted.

Methods:

A systematic random sample of 200 patients with BD attending a general hospital psychiatric unit was chosen. They were assessed using the clinician and self-rated versions of the National Institute of Mental Health—Retrospective Life Charts, the lifetime version of the Columbia Suicide Severity Rating Scale, the Medication Adherence Questionnaire, the Indian Disability Evaluation and Assessment Scale, and the Presumptive Stressful Life Events Scale.

Results:

The mean age of onset of BD was 26 years. About 11%–13% of the illness was spent in acute episodes, mostly in depression (60%). Episode frequency was 0.4–0.6 annually. The first episode was more likely to be manic, and manic episodes outnumbered depressive episodes. The average duration of episodes was 3 months. Depressive episodes were longer and the time spent in depression was greater than mania. Psychotic symptoms (48%), a mania-depression-interval pattern (61%), and recurrent mania (19%) were common while rapid cycling and seasonal patterns were uncommon. Comorbidity (40%), functional impairment (77%), and lifetime nonadherence (58%) were high, whereas lifetime suicide attempts (16%) were low. Stressful life events were very common prior to episodes (80%), particularly early in the illness.

Conclusion:

This study suggests differences between Indian and Western patients in the demographic profile and the course and outcome of BD. A more benign presentation in the current study including Indian studies is indicated by their later age of presentation and illness onset, higher rates of marriage, education, and employment, a mania predominant course, lower rates of rapid cycling, comorbidity, and suicidal attempts. Factors associated with better outcomes such as longer time to recurrence, Manic Depressive pattern of illness, and low rates of hospitalizations also appear to be commoner in our study and also in other Indian studies.

Authors: Sahu Manoj K. , Dubey Rajesh K. , Chandrakar Alka , Kumar Mahesh , Kumar Mahendra
Published: October 2022

Depression is associated with hyperactivity of the hypothalamo pituitary adrenal axis. Cortisol is a steroid hormone, released from the adrenal gland and is considered to be a biological marker of stress and anxiety. Serum or plasma cortisol levels have been previously studied in depressive patients but reported contradictory results. The present meta analysis aims to assess the serum or plasma concentration of cortisol in depressive patients compared with controls. We have conducted a systematic review with sequential meta analysis according to the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) guidelines. Web of Science, PubMed, Scopus, and PsycINFO databases, and published reference lists were searched up to January 2021. We have conducted a systematic review on PubMed for the following search (MeSH) terms (“Hydrocortisone”[Mesh]) AND “Depressive Disorder”[Mesh]). The RevMan 5.3 and Open Meta Analyst software was used with the standard mean difference (SMD) and 95% confidence intervals (CIs). The Jamovi and Open Meta Analyst Software were used to evaluate the publication bias, sensitivity analysis, and meta regression as possible sources of heterogeneity. Seventeen studies having a combined population (n) of 1400 (743 depressive patients and 657 controls) had satisfied the inclusion criteria for serum or plasma cortisol. The pooled SMD of the serum or plasma cortisol levels in depressive patients compared with controls was 1.18, (95% CI: 0.84, 1.52; P < 0.00001) with I2 = 85% (Ph < 0.00001). This meta analysis indicates a statistically significant mean difference in serum or plasma cortisol between depressed patients and controls. Meta analysis concluded that serum or plasma cortisol can differentiate depressed patients from nondepressed controls.

Authors: Ghosh Abhishek , Mahintamani Tathagata , Sharma Kshitiz , Singh Geetesh Kumar , Pillai Renjith R. , Subodh BN , Basu Debasish , Mattoo Surendra K.
Published: October 2022

Context:

Telemedicine has become one of the essential modes of healthcare delivery. Different aspects of the physician–patient relationship during tele and in-person consultation need to be studied.

Aims:

This study aimed to compare perceived empathy and therapeutic relationship between tele and in-person consultation and assess the patient’s satisfaction during teleconsultation for substance use disorder (SUD).

Methodology:

We consecutively recruited 100 adult patients with SUD, registered to the tele-addiction service between June and September 2020, and experienced both video and in-person consultations. We assessed therapeutic relationships, perceived empathy (for teleconsultation and in-person consultation), and patients’ satisfaction (with teleconsultation) with specific scales. We compared the scores of the therapeutic relationship and physician empathy scales for tele and in-person consultation.

Results:

The mean age of the patients was 35.5 (±10.4) years. Sixty percent had alcohol, followed by opioids (42%) and cannabis dependence (24%). Sixty percent of patients had comorbid tobacco dependence. Telehealth satisfaction (TSS) rating shows around 40% of patients had difficulty accessing the telehealth service and 7% felt their privacy was poorly respected. The mean total therapeutic relation (STAR) (t = −14.4; P < .001), positive collaboration (t = −12.8; P < .001), positive clinical input (t = −11.9; P < .001), and total Patient’s Perceptions of Physician Empathy (PPPE) score (t = −8.4; P < .001) were lower in the teleconsultation than in-person consultation group. TSS was positively correlated with positive collaboration, positive clinician input, and STAR total score.

Conclusions:

Our study suggests a stronger therapeutic relationship and higher physician empathy during in-person consultations. Poor accessibility and privacy concerns were critical challenges in telehealth service. TSS and therapeutic relationships positively influence each other.
Demographic Characteristics, Predisposing Factors, Clinical Presentations, Echocardiographic Findings, Complications, and Outcomes of Patients with Viridans Streptococcal Endocarditis
Authors: Moradnejad Pardis , Boudagh Shabnam
Published: October 2022

Background:

Several microorganisms are associated with infective endocarditis (IE), but the most common IE causes are staphylococci and streptococci. Among streptococci, the viridans group streptococci are responsible for a considerable percentage of all IE cases.

Methods:

Since 2006, the Iranian Registry of Infective Endocarditis has recorded information regarding all adult patients with a definite or possible IE diagnosis according to the modified Duke criteria. Patients with viridans streptococcal endocarditis were detected through three blood culture sets. The patients' demographic characteristics, predisposing factors, clinical presentations, and echocardiographic findings were recorded.

Results:

Of 731 patients diagnosed with endocarditis, viridans streptococci were found in 46 (6.3%) patients, consisting of 28 (60.9%) men and 18 (39.1%) women at a mean age of 42.56 ± 15.46 years, who were subsequently included in the study. Among the 46 patients with viridans streptococcal endocarditis, 26 had a subacute course, whereas 20 had an acute course. Vegetation was detected in 35 patients. All the patients were treated with the standard antibiotic regimen for viridans streptococcal endocarditis, and cardiac surgery was performed on 16 patients.

Conclusions:

Clinicians should pay sufficient heed to the following points in all cases of viridans streptococcal endocarditis: firstly, an appropriate antibiotic regimen must be based on a precise minimal inhibitory concentration determination for the usual antibiotics. Secondly, since prolonged antibiotic therapy is crucial to the eradication of microorganisms within vegetation, all patients with viridans streptococcal endocarditis must receive an adequate therapy course.

Published: October 2022

Reports of cases of noma in Nigeria remain scarce despite its known and devastating effects on victims. This report presents a retrospective cross-sectional study based on data regarding on patients with noma encountered incidentally during Oral Health Advocacy Initiative outreach on orofacial diseases across 34 states and the Federal Capital Territory in Nigeria over 10 years (2011–2020), which was aimed at contributing to an understanding of the epidemiology of noma in Nigeria. The data were collated and analyzed, and are presented in frequency distribution tables and charts. A total of 7,195 patients with noma were encountered. The northeastern region had the greatest number of patients (n = 1,785, 24.8%) whereas the southwestern region had the least (n = 196, 2.7%). When aggregated by state, Ondo State had the least number of patients (n = 31, 0.4%) whereas Kano State had the greatest (n = 623, 8.7%). Patient age ranged from 3 to 70 years, with a slight male preponderance (56.9%). This report highlights the fact that noma is prevalent in Nigeria but remains neglected, with extensive but preventable physical, emotional, and social debilitation and devastation of the victims across all age groups. There is a need for a more robust survey to determine the true burden of the disease. There is also an urgent need for collaboration between governments and nongovernmental organizations to institute appropriate interventions by way of public education and enlightenment, as well as case detection and early treatment to mitigate the devastating consequences of delayed or poorly managed cases.
The profile of Hip and Knee Periprosthetic Joint Infection cases at Dr. Cipto Mangunkusumo Central National Referral Hospital
Authors: Wibowo Eko Prasetyo Adi , Dilogo Ismail Hadisoebroto
Published: October 2022

Background: The most troubling complication of joint replacement procedures is periprosthetic joint infection (PJI). Pathogen identification increases the likelihood of successful treatment. The data of PJI are mostly unpublished in Indonesia. In this study we aimed to investigate the characteristics of PJI of a national hospital in Indonesia. Material and methods: This research was a cross-sectional study. The inclusion criteria were patients diagnosed with PJI confirmed by examination of fluid exudate culture, sedimentation rate and C-Reactive Protein, which was accompanied by dislocation, fracture and/or loosening of the prosthetic joint and diagnosed between January 2019 to July 2020. Result: The mean age of patients who underwent revision surgery for PJI was 50.0 ± 14.69 years-old with a slightly higher proportion of men (63.6%). Of the 21 patients, some patients had a history of surgery more than once. The clinical outcome was assessed with the Harris Hip Score (HHS) and the Visual Analog Scale (VAS). The mean HHS of all hip replacement surgeries increased from 61.4 (48.15 to 68) before surgery to 82.5 (75.7 to 84) at the 12-month follow-up post last surgery (p=0.03). Likewise, the VAS value decreased from 3 (2 to 4) before surgery to 2 (1 to 2). Conclusion: Gram positive bacteria were more prevalent compared to gram negative bacteria. The difference in the microorganism spectrum could be one of several factors. This pattern should be explored in the future by adding more samples to the study. Overall, the clinical outcome was better in both total hip and knee arthroplasty patients, measured by the Harris hip score, visual analog scale, and the knee society score
Treatment of Severe Knee Flexion Contracture After Below Knee Amputation Using Hinged Ilizarov Ring External Fixator
Authors: Brilianto Bagus Iman , Mariyanto Ismail
Published: October 2022

Flexion contracture of the knee is a common complication found after Below Knee Amputation (BKA). This condition is caused by muscle imbalance and prolonged stump malpositioning after BKA. Acute surgical correction of this deformity associated with high rates of complications.A 39-years-old man with chief complaint flexion contracture after BKA 3 months before. Physical examination showed flexion contracture deformity with knee range of motion at 90° to 120° with no possibility of further knee extension. This condition prevented him to use prosthesis and start walking exercises. Gradual correction of flexion deformity was performed using hinged Ilizarov ring external fixator with the rate of distraction was 1mm/day to prevent soft tissue and neurovascular complications. After 90 days of distraction, full extension of the knee joint was achieved with no complications.Gradual correction of knee flexion contracture using hinged Ilizarov device greatly reduced the complications risk of acute deformity correction with open surgery. This technique provides more advantage of minor operative trauma with a gradually controlled correction, permitting the soft tissue to regenerate, thus lowering the risk of neurovascular complications.
Study of the Effect of Adding Dune Sand to Tuff in Saharan Road Construction

Published: October 2022

The south region of Algeria is characterized by a wide surface, a scattered population and a very small ratio of road length per habitant. To allow the development of agricultural, industrial and touristic activities between different cities in the south of Algeria, it is necessary to maintain and to develop the road infrastructure.  However the development of these infrastructures necessitates the use of huge amount of certified aggregates from quarries which is not available in the vicinity of the need. For these raisons, in the framework of sustainable development, a strategy which consists in using local materials like fine sediments (dune sand) and other types of material is engaged. The materials constituting the road layers, until today, have been limited to certain so-called noble materials (gravel, aggregates, etc.), but these are being depleted as a result of the intensive exploitation and the scarcity of quality careers. Gypso-limestone encrustation tuffs, the most used materials in pavements (base course and base course) in the Saharan areas such as southern Algeria, have shown acceptable behavior for many years until these last days, when this type of material begins to present certain limits under the effect of the intensity of the traffic. In order to promote the abundant wind sands in these regions, we are interested in developing the dune sands in the pavement as a mixture with the tuffs. The present work presents a contribution to the study of the behavior of the tuff of the Adrar region (South of Algeria) alone and mixed with the sand dunes in different formulations. The aim is to evaluate the evolution of mechanical properties including resistance to simple compression, the ability to compaction and punching (RBC). The work also discusses the influence of the addition of cement in low levels on the performance of the mixture.

Authors: Dahia Ahmed , Zidouni Faiza , Boualouache Amine , Cheridi Amina Lyria , Dadda Amel
Published: October 2022

The present paper consists of a numerical investigation carried out for primary break up analysis of a vertical water jet. Many parameters impact the flow development such as velocity, turbulence and nozzle shape. In this work, two types of nozzle geometries have been performed, the first is a capillary circular and the second is conical. The calculations have been performed using the CFD Code Fluent of ANSYS, considering laminar and turbulent flow regimes. While turbulence was modelled using RNG k-ε of RANS approach. The main results show that the jet evolves differently in the two considered nozzle geometries comparing the jet intact lengths, drop sizes and distance between successive drops. It is observed that the turbulence increases substantially the jet intact length and enables the jet breakup at the lower part of the water column. For the conical nozzle case, the jet instabilities grow quickly resulting a drop size in the same order of the jet diameter and an intact length larger in comparison with the circular nozzle case.
A New combined MPPT-Pitch Angle control of a Large Variable Speed Wind Turbine in Different Operating Areas based on Synergetic control
Authors: Mahgoun Mohemmed Seddik , Badoud Abd Essalam
Published: October 2022

The aim of this paper is to create a novel combination between two controls, maximum power point tracking (MPPT) and Pitch angle control system of a variable-speed wind turbine. The main objective sought is to achieve the maximization of the power produced by the fixed pitch angle turbine through the MPPT control in the zone 02 of operation. Then, limit the power to its nominal value by using the Pitch control with variable pitch angle in zone 03 of operation. Our contribution will be to propose strategies based on two types of controllers. The first is the control by the MPPT control, it is applied in light winds to extract the maximum power. The second is Variable Pitch Control, which is applied in strong winds to keep power constant at its nominal value, as well as protecting the wind turbine from high winds. For this, linear and non-linear control laws (PI, SC) respectively are implemented to achieve the defined objective. The simulation results show the feasibility and effectiveness of the techniques used.

Principio precautorio ambiental y derecho del trabajo: propuesta de integración a partir de un fallo argentino
Authors: Lerussi Romina Carla
Published: October 2022

El presente texto tiene dos objetivos. En primer lugar, exponer sintéticamente cuatro argumentos de un fallo argentino dictado hace ocho años a partir de un juicio de sobrevaloración del principio precautorio como garante de bienes públicos ambientales. En segundo lugar, introducir algunas reflexiones a partir de la siguiente paradoja: el trabajo que ensucia (destruye, contamina) y atenta contra bienes públicos ambientales es el trabajo que también protege el Derecho del Trabajo. La integración sistemática, no ilustrativa, del principio precautorio ambiental en el Derecho del Trabajo supone seguir robusteciendo sus bases sociales desde el punto de vista del control de constitucionalidad en Argentina.

relación del becario frente a la nueva regulación del contrato formativo. Zonas de concurrencia y elementos de distinción
Authors: Montes Adalid Gloria María
Published: October 2022

Los debates en torno al empleo juvenil han adquirido en España una importancia creciente en los últimos años. Aquellos que terminan sus estudios y preparan su entrada en el mercado laboral se enfrentan a una carencia de formación práctica y experiencia en los entornos de trabajo.

A este tenor, existen diversas figuras contractuales o relaciones jurídicas que se ajustan a lo que el nuevo profesional requiere y le facilitan y aceleran su inmersión en el mundo laboral, entre las que encontramos la figura del becario o los contratos formativos. Que, si bien pueden tener notas comunes, tienen naturalezas distintas: uno se considera una relación laboral propiamente dicha, y otro no.

A través de un recorrido normativo en el panorama español y europeo, el cuerpo de este artículo establece el marco regulador de las mencionadas figuras, aludiendo al origen del problema (discernir en la práctica la frontera que existe entre la relación de beca y el contrato de trabajo), contribuyendo al debate sobre la relación jurídica especial de los becarios, su diferenciación con los contratos formativos y un acercamiento a la doctrina y a la jurisprudencia, a través del análisis de las figuras del becario, falso becario, contratos formativos y las bases que determinan la naturaleza del vínculo. Se anotan, como colofón, algunas posibles soluciones; y lo más importante para la determinación de la existencia o no de beca: la realidad fáctica.

Indonesia is committed to innovating and making breakthroughs in micro- hydro energy development. However, the problem is the lack of multi-stakeholder roles, especially local communities in its development, causing the poor operation of micro- hydropower plants. This research aims to apply the Spiral Cycle Micro-hydro Community System (SCMCS) Model through an eight-stage cycle process for the development of the Kedungrong micro-hydro power plant (MHPP) in Yogyakarta. The methods used are a qualitative approach, collecting data in the form of field observations, in-depth interviews and forum group discussion. The results and new findings indicate that SCMCS requires at least four cycles to be useful and sustainable. First is enhancing institutional, social and environmental aspects. Second is enhancing the technical aspects. Third involves improving the economic aspects. Fourth is optimizing the use of micro-hydro energy for micro-small enterprises. This model has successfully developed and preserved the MHPP project through integrated multi-stakeholder community participation in rural areas.

Published: October 2022

Learning mathematics is strongly related to brain function. Neuroscience research has defined how different areas of the brain will mechanise and respond to the complex process of learning mathematics. This interrelationship requires practical details and clarification. However, a lack of neuroscience information and literacy inhibits efforts to improve the mathematics learning environment. Therefore, this study aims to determine the impact of neuroscience literacy on the mathematics learning environment of students. A systematic literature review was conducted using the PRISMA strategy, with the input of keywords into databases such as Scopus, ScienceDirect, Google Scholar, Pubmed and Web of Science, to search for the best articles on the subject. The year of publication, objective, content, results and dense discussions were analysed. The results suggest that several aspects of neuroscience literacy like principles, mechanisms and practices, are deemed important and may bring a positive impact in learning mathematics. The attributes affect cognition, psychology and behaviour in shaping and sustaining the students’ mathematics learning environment based on personal, social, organisational and physical components or virtual spaces. As a result, neuroscience should be considered as an alternative to transforming and improving the outcome of mathematics learning among students.

SPBU (Stasiun Pengisian Bahan Bakar untuk Umum) merupakan prasarana umum yang disediakan untuk masyarakat luas, guna memenuhi kebutuhan bahan bakar. Untuk meningkatkan efisiensi perusahan dan memperbaiki kualitas layanan, Pertamina menawarkan beberapa layanan di SPBU, salah satunya penerapan konsep self service atau pelayanan mandiri. Konsep ini menjadi persoalan ketika banyak pengendara yang tidak mengetahui cara mengoperasikan gagang selang bensin, sehingga antrian berjalan lambat. Kelemahan lainnya, dengan konsep self service yakni pengendara tidak dapat lagi mengisi bensin full tank, karena sebelum mengisi tangki pengendara terlebih dahulu menentukan berapa jumlah pembelian Perancangan ini bertujuan mengubah tampilan desain guna mempermudah pengguna stasiun pengisian bahan bakar tersebut. Perancangan ini menggunakan metode psikologi desain untuk mendapatkan sebuah solusi baru tentang permasalahan yang ada, dengan menganalisis kebiasaan pengguna dalam mengoperasikan dispenser dan melakukan analisis paper prototyping. Hal ini bertujuan untuk mendapatkan desain interface yang sesuai dengan kebutuhan pengguna. Dengan adanya permasalahan yang dihadapi tersebut maka, akan ditelaah lebih lanjut korelasi antara dispenser SPBU dengan cara orang menggunakannya. Sehingga dengan didapatkannya hasil tersebut diharapkan agar pengguna menjadi lebih mudah dalam melakukan pengisian bahan bakar di SPBU.

Increasing video content on social media has led to more people doing video blogging or referred as video bloggers (vloggers). It affects the number of vloggers in Indonesia, reaching half the total number in the world. Vloggers need a bag to carry equipment so that the equipment is stored correctly and undamaged when creating content outdoors. The specific bags for camera equipment on the market still do not fulfill their requirement.  These conditions require vloggers to provide various bags, while vlogger activities and equipment always change according to content needs. This study aims to answer the problems experienced by vloggers by increasing the effectiveness of the bag through concepts, systems, access, and compartment layouts. The method used in developing the compartment starts from collecting data such as questionnaires and interviews to identify problems, observation of existing products and product references, activities studies, continued analysis data, design concepts to production, and product testing.

Authors: Chen Jui-Lung
Published: October 2022

Abstract

Technological and vocational education has developed in Taiwan for over 60 years and played a crucial role in cultivating talents for infrastructure construction and driving industries and economic growth there. Universities and colleges across Taiwan have introduced resources from various industries and adopted the two-teacher system to strengthen their practical teaching in recent years. To be specific, these schools hire experts in various industries for collaborative teaching and encourage enterprise visits, thereby presenting more opportunities for students to get involved in experiential learning. This study explored the learning outcomes of industry expert collaborative teaching and enterprise visits on students studying in business schools of universities of technology in Taiwan. Moreover, policies announced by the Ministry of Education in Taiwan were introduced and analyzed. Finally, the specific suggestions proposed in this study can be served as a reference to industries, the government, universities, and institutions in their effort to innovate teaching methods and improve teaching quality.

Published: October 2022

Background: This is an experiment report on Health Information Systems’ (HIS) integration project. It reports a successful implementation experience of HIS integration with the pharmaceutical Pyxis system that is used for medication dispensing. The Information Technology (IT) department in King Khalid Eye Specialist Hospital (KKESH) in the Kingdom of Saudi Arabia led this project to its final successful deployment. Rhapsody Engine successful adoption in the integration process helped KKESH achieve their productivity goals by improving hospital’s staff daily duties and clinical workflow. It also eliminated the system’s errors and alerting notifications. Objective: This experience paper discusses three main questions: What is the power of systems integration? What are the systems’ integration standards? What are the main key performance indicators for IT related projects? It also discusses the implemented solutions that solved many potential problems that could be encountered by similar big organizations such as the KKESH. Several drawbacks of having isolated internal systems will be discussed. Similarly, many difficulties encountered during the integration process were demonstrated in detail. Henceforth, this experiment report can be considered as a road map for medical organizations with similar size and limitations should they consider integrating their internal systems for better health care management and productivity
Myeloproliferative Syndrome – A Diagnosis on The Border Between Medical Specialties: Case Report
Authors:   Dr. Ion Cantacuzino” Clinical Hospital, Bucharest, Romania, Scarlat Gabriel
Published: October 2022

Background: Myeloproliferative disorders define a vast and heteregenous group of neoplastic entities, characterized by malignant proliferation of blood cells. These may affect multiple tissues, some of these malignancies involving organs in which there is lymphoid tissue. Case Report: A 81-year-old female patient was admitted to the Department of Internal Medicine with moderate-to-intense spontaneous pain in the left hypochondrial and in the left abdominal flank, associated with generalized fatigue and loss of appetite. According to the personal medical history, the patient is known with type II diabetes mellitus, being under treatment with oral antidiabetics (metformin 1000 mg), and arterial hypertension under treatment with candesartan. Upon admission, the physical examination revealed cutaneous and mucosal pallor and marked physical weakness. Abdominal palpation revealed pain in the left hypochondrial and in the left abdominal flank, associated with firm and massive splenomegaly, descending towards the umbilicus. Abdominal ultrasound confirmed massive splenomegaly, associated with moderate hepatomegaly. Blood analysis revealed several modifications, indicative of hypochromic normocytic anemia, associated with lymphocytosis, thrombocytopenia and neutropenia. C-reactive protein (CRP) serum levels were in normal range upon admission. All of these modifications suggested a possible leukemogenous or lymphoid malignancy, which resulted in the patient’s transfer towards the Department of Hematology, for further investigations
Navigating the Rural Clinical Education Pathway in the Time of a Pandemic: Opportunities and Challenges
Authors:   Monash University, Hall Lisa
Published: October 2022

The outbreak of the COVID-19 pandemic has changed everything about the world we live in, in 2020. It is having obvious impacts on the way we teach and the way we learn. In Victoria, Monash Rural Health Bendigo is one of the few places that has managed to continue clinical health education and clinical placements throughout 2020 - albeit in modified forms. Monash Rural Health Bendigo provides clinical years education to a cohort of between 100 and 130 Third, Fourth- and Fifth-Year Monash Medical students in a rural setting. It is largely an 'apprentice based' model of learning where the students get access to rural clinical sites and rural health experts as well as a state-of-the-art clinical skills and simulation lab to undertake the clinical years of their medical degree. But what happens to this kind of model during a pandemic induced shut down such as was experienced in 2020? This paper explores the challenges but also opportunities for students pursuing a rural health pathway in the midst of a public health emergency. It examines the findings of the COVID-19 Educational Evaluation conducted in Bendigo throughout 2020 and reveals the advantages but also the unanticipated consequences of students choosing to study rurally in the midst of a global pandemic.

Authors: Sezer Ozlem , Gunal Ozgur , Aci Recai , Keskin Adem
Published: October 2022

Background and objective: Thrombotic and microangiopathic effects have been reported in Coronavirus Disease-2019 (COVID-19) patients. In the present study, we aimed to examine the relationship between hereditary thrombophilia factors and the clinical picture severity of COVID-19 patients.
Methods: Ninety COVID-19 patients were included and grouped according to the severity to three groups: severe/critical (n=30), mild/moderate (n=30) and asymptomatic (n=30). Hereditary thrombophilia genetic markers [prothrombin (FII) G20210A, factor V Leiden (FVL) G1691A, factor XIII (FXIII) V34L, methylene tetrahydrofolate reductase (MTHFR) A1298C and C677T, and plasminogen activator inhibitor-1 (PAI-1) 4G & 5G] were genotyped for all patients.
Results: Seventeen (18.9%) patients had the polymorphism 4G/4G PAI-1 and 48 (53.3%) had 4G/5G. In addition, the heterozygous GA FVL, MTHRF677CT, and MTHRF1298AC polymorphisms were detected in 11 (12.2%), 26 (28.9%), and 38 (42.2%) patients, respectively. The rate of severe/critical patients with PAI 4G/5G gene polymorphism was higher than the asymptomatic+moderate/mild patients, and the rate of severe/critically ill patients with PAI 4G/4G polymorphism was found to be lower than the asymptomatic+moderate/mild patients. No difference was evidenced between the distribution of deceased and survivors of the genotype groups.
Conclusions: In the present study, we found that heterozygous 4G/5G PAI-1 polymorphism is associated with critical or severe COVID-19 picture, and that FVL, MTHFR, FXIII, and prothrombin polymorphisms were not directly related to COVID-19 severity.
