Diagnosing Mathematics Ability of Technology Students: Misconceptions in Algebra
Authors: Rathnayake Rovini , Jayakody Gaya N 
Published: May 2022

Catering to a long-standing need in the country, the technology stream was introduced to the G.C.E. (A/L) in Sri Lanka in 2015 with one compulsory subject Science for Technology formed by combining six Science subjects including Mathematics. There is no argument that a sound Mathematics background is essential to produce a good technology graduate. Not only do technologists need Mathematics knowledge in technological applications, but also the logical, analytical, and critical thinking developed through the learning of mathematics is essential for them in solving problems. Hence, technology faculties around the country observe that the command in mathematics of their new entrants needs improvement. As a diagnosis and to uplift their mathematics achievement, this study aims to explore one aspect of their mathematics knowledge: common mistakes and misconceptions. This paper reports on the extent to which algebraic mistakes are made by students entering Technology Faculties. The data for this study comes from a three-week online intensive mathematics course that students follow, prior to commencing their degree program. Students ask to respond to ten questions designed to capture errors in algebraic manipulations. The analysis of data shows a lack of understanding of the intricacies of division by zero consequently resulting in cancellation errors, erroneous manipulations of algebraic expressions, and improper use of parenthesis and priority of exponents in the order of operations. Another mistake is extending the distributive property of multiplication over addition erroneously to distributing multiplication over multiplication. More importantly, the data reveals a training these students have received in school that is mathematically less precise and therefore highlights the need to make students unlearn these erroneous habits that is ingrained in them for many years. Further, these results urge instructors to incorporate purposeful remedial actions into their early mathematics courses to better prepare them for their future technology.

Published: May 2022

The quality of the components of the environment significantly affects the level of health of the athlete, his ability to work, vitality and life expectancy.
Living in an environmentally friendly, healthy and safe environment is one of the most important conditions for great achievements in sports. This paper presents data on the physical factors of negative air pollution that can affect the health and performance of athletes. Physical components of the environment, the content of which should not exceed the norm, are solid physical compounds, temperature and humidity, the presence and natural level of radioactivity, magnetic field strength and others. Hygienic standards are set for all physical negative factors - maximum permissible concentrations, doses, levels, which must be taken into account when assessing the environment of athletes, because high sports achievements are provided by a multi-vector set of measures, tools, technologies, including an important component of stressful, exhausting lifestyle of athletes is to be in the most harmonious environment, which corresponds to scientifically sound indicators. It is inadmissible to neglect any element.
It should also be borne in mind that at low levels of exposure close to acceptable, the most likely (frequent) is the summation negative effect, ie at low concentrations may increase the effect (potentiation).)
Atmospheric pollution has toxic, mutagenic, carcinogenic and allergenic effects, causes deterioration of the athlete, reduces his life expectancy, reduces efficiency, reduces biological productivity, counteracts normal development.
Air pollution negatively affects not only the athlete, but also the various purposes of the building, the vehicles in which he is. Therefore, a differentiated approach is required when choosing a location for the construction of sports facilities, training and competitions of athletes. To use it, you need to know the negative effects of the complex as a whole changed the properties of air and each of its components separately. Some data on the issues raised are reflected in this paper.
Giant sacrococcygeal teratoma in a neonate: illustrative case
Authors: Neupane Durga , Dahal Alok , Lageju Nimesh , Jaiswal Lokesh Shekher , Bista Nimesh , Sapkota Aakriti 
Published: May 2022

BACKGROUND
Sacrococcygeal teratomas (SCTs) are tumors that emerge in the sacrococcygeal area and contain tissue from all three germ layers. SCT affects about 1 in every 35,000–40,000 live births, with malignant transformation becoming more common as the patient gets older. Ultrasound helps in prenatal diagnosis. Surgical resection is the mainstay of treatment.

OBSERVATIONS
A couple gave birth to a neonate with a small mass over his sacral region that progressively increased in size. Diagnostic magnetic resonance imaging was performed, and a diagnosis of giant SCT was established. Complete resection with flap reconstruction was performed. In regular follow-up, he is in a good state of health.

LESSONS
One of the most common tumors in infancy, SCT should be carefully diagnosed. SCT is often confused with neural tube defects such as myelocystocele or myelomeningocele. Complete resection with appropriate reconstruction can ensure better treatment, and close follow-up until adulthood is recommended to keep a close view on its possible recurrence and to improve prognosis. Postoperative complications such as infection, bleeding, and urethral complications should be carefully watched.

BACKGROUND
Intraoperative indocyanine green video angiography (ICG-VA) is useful for determining the extent of lesion removal during cerebral arteriovenous malformation (AVM) surgery. The authors described a case of surgical removal of an AVM presenting with early venous filling mimicking a residual nidus on intraoperative ICG-VA.

OBSERVATIONS
A 7-year-old girl experienced a sudden disturbance of consciousness. Computed tomography revealed right frontal intracerebral hemorrhage. Digital subtraction angiography showed a Spetzler-Martin grade 1 AVM in the right frontal lobe. The patient received surgical removal of the AVM after endovascular embolization. After removal of the nidus, the first intraoperative ICG-VA revealed early venous filling of the cortex around the excision cavity. Additional resection of the cortex around this area was performed. Histopathological examination of the lesion revealed a dilated normal vascular structure without an AVM.

LESSONS
Early venous filling in the surrounding brain tissue after AVM removal does not necessarily indicate a residual nidus. The need for additional resection of the lesion depends on the eloquence of the area.

Published: May 2022

Pengetahuan dasar topografi anatomi dari nervus fasialis sangat penting untuk pada aplikasi klinis. Ukuran nervus fasialis yang sangat kecil dan kurang nya penanda struktur saraf tersebut padadaerah wajah menjadikan cabang ekstra kranial dari nervus fasialis sulit untuk diidentifikasi. Untuk itu pentingnya kemampuan ketrampilan diseksi pada beberapa jaringan seperti jaringan yang segar dan jaringan yang sudah dilakukan preservasi. Tujuan penelitian ini adalah untuk membandingkan diseksi anatomi dari nervus fasialis preaparat dari jaringan yang segar dan dari jaringan yang sudah dilakukan preservasi. Metode yang digunakan untuk menentukan topografi ekstra kranial nervus fasialis dilakukan dengan diseksi anatomi pada daerah kepala dari 3 jenazah yang berasal dari Departemen Forensik dan 3 kadaver laboratorium. Garis insisi dimulai dari garis tengah melewati glabela,menuju puncak hidung dan sampai pada lekukan vertikal antara hidung dan mulut. Kemudian dengan menyusuri bagian-bagian kulit, lapisan demi lapisan akan dipisahkan untuk mengidentifikasi cabang dari nervus fasialis. Hasil penelitian ini menunjukkan bahwa pada diseksi anatomi dengan menggunakan jaringan yang sudah dipreservasi, nervus fasialis dan cabang-cabangnya mudah untuk diidentifikasi, tetapi sulit untuk memisahkan lapisan-lapisan kulit daerah wajah dari lapisan Superfisial Musculo Aponeurotic System (SMAS).Kesimpulan penelitian menunjukkan bahwa identifikasi ekstra kanial nervus fasialis lebih mudah dilakukan pada jaringan yang sudah terpreservasi. Sedangkan untuk mengidentifikasi lapisan lapisan kulit pada bagian wajah lebih mudah dilakukan pada jaringan yang masih segar.
Modelización climática a escala regional: ¿Modelos globales o regionales?
Authors: Tapiador Francisco J. 
Published: May 2022

Estamos inmersos en una emergencia climática que afecta a todo el planeta y que ejerce impactos muy diferentes sobre diferentes regiones. Conocer cuáles van a ser los mayores cambios en el futuro en función de una serie de caminos socioeconómicos es de una importancia fundamental para evaluar las respuestas de nuestras sociedades a los retos que se presentan. Las dos variables de mayor interés para atender a esta emergencia climática son la temperatura y la precipitación. Los cambios en ambas variables afectan no solo a la biota sino también a la actividad humana, por lo que el estudio de su variabilidad es primordial en sectores tales como la agricultura, la industria o el turismo.
Para conocer cuáles van a ser los cambios en la precipitación y en la temperatura es necesario recurrir a los modelos de clima, de los cuales hay casi un centenar hoy el día. Solo con ellos podemos analizar, por ejemplo, los cambios en los ciclos de las precipitaciones, un tema crítico para la agricultura y la gestión ambiental (Tapiador et al. 2016). Para realizar estos estudios contamos con dos estrategias principales de modelización: usar modelos regionales, o modelos globales. En esta breve nota pretendo apuntar los pros y los contras de cada uno de ellos, resumiendo sin entrar en profundidad algunos resultados de las contribuciones propias sobre el tema. Para una información más en detalle, se remite al lector a los artículos correspondientes.
¿Qué es un modelo de clima? Un modelo de clima es un programa informático que recoge todo nuestro conocimiento actual sobre cómo funciona la atmósfera, el océano, la criosfera y la biosfera. Gracias a ellos, y a partir de sobre todo las ecuaciones básicas del movimiento de los fluidos, podemos predecir el comportamiento del clima. Esto es muy diferente a los métodos puramente estadísticos, los basados en el análisis de las series temporales. Aquí no se trata de aprovechar funciones de autocorrelación espacial o temporal, o de explotar covariabilidades. Los modelos de clima emplean ecuaciones físicas básicas (en el sentido de fundamentales) y son mucho más potentes, mucho más precisos, y en resumen, las únicas herramientas viables que tenemos para saber algo sobre los impactos del clima en el futuro.
Comparing NGOs and Public Health Services Treating Leprosy and Tuberculosis in a City of Bangladesh

Published: May 2022

Background: Leprosy and Tuberculosis (TB) patients have choices of receiving treatment between Non-government Organization (NGO) operated and public hospital.
Objective: This study compared patients’ level of satisfaction between NGO and public hospitals treating Leprosy and TB.
Methodology: The study was conducted in Khulna city during February-April, 2020. Using random sampling technique, questionnaire survey among patients and in-depth interviews among seven doctors and health service providers were conducted. Wilcoxon Signed Rank Test was employed to compare the difference in the level of satisfaction between NGOs and public hospitals. The sample patients’ opinion on NGO and public health services for Leprosy and TB were synthesized from the perspectives of doctors and health service providers.
Results: A total number of 53 patients were recruited for this study. The findings of the study suggested that most of the Leprosy and TB patients belonged to the low-income group, which led to ignoring the symptoms and delayed disease detection. In contrast to the NGO led health facility where the level of patients’ satisfaction was high, public hospitals performed poorly for Leprosy and TB treatment. The stark difference between NGO operated and the public hospital was due to the specialized care by NGO hospitals, and due to the overwhelming number of non-communicable disease patients at the public hospitals. Access to funding, logistics and training, and a small number of patients, spurred better services by the NGO operated hospitals than their public counterparts.
Conclusion: The study conclusively proved that NGO operated hospitals offered better health services than public ones for Leprosy and TB patients in Khulna.
