Published: June 2023

El diseño de sistemas de monitoreo y/o control se basa en modelos matemáticos en el tiempo t, que implican ecuaciones diferenciales y transformadas de Laplace para su solución. Al asociar estos modelos con sistemas discretos y al usar microcontroladores o computadoras para digitalizar estos sistemas, se hace necesario el uso de la Transformada-z. Esta última requiere que se conozca el tiempo de muestreo utilizado, para que todos los modelos concuerden en sus resultados.
El presente trabajo muestra un método práctico para determinar el tiempo de muestreo. Se utilizó el kit de desarrollo ESP-32-S2 y una red con una resistencia y un condensador. Mediante un programa en lenguaje C/C++ y un osciloscopio, se midió el tiempo de muestreo. Se realizaron experimentos para diferentes condiciones de operación del sistema de adquisición de datos, registrando el voltaje del condensador en respuesta a una alimentación escalón unitario. Los resultados reales se compararon gráficamente con los resultados en t, s y z, y se calculó el error entre la respuesta en t y los resultados prácticos.
Esto demostró que el método propuesto genera una buena medida del tiempo de muestreo y que los resultados de los modelos en todos los planos concuerdan con los obtenidos en la práctica. Con esto, esperamos motivar a estudiantes y profesionales a aplicar las matemáticas en el diseño de sistemas digitales, fomentando el uso de herramientas de simulación que permitan el desarrollo de sistemas más rápidos y eficientes. Además, buscamos fortalecer trabajos relacionados con sistemas embebidos, sensores inteligentes, la Internet de las cosas y la industria 4.0.

Abstract

Objective. Hypothyroidism is a syndrome characterized by clinical manifestations associated with thyroid hormone deficiency. The thyroid hormone plays a pivotal role in the hematopoietic system and stimulates precursors of erythropoietin gene expression. Therefore, anemia is a common clinical manifestation in hypothyroid individuals. The goal of this study was to carry out a prospective analysis of the prevalence of anemia, its types, and the etiology behind the differing anemia morphology among hypothyroid patients.

Methods. The study was conducted with a sample size of 100 patients suffering from hypothyroidism. The methodology of the study included a questionnaire and consent filling for general information followed by a complete blood test for assessment of blood count, peripheral smear, FT3/FT4 (free triiodothyronine/thyroxine), anemia profile, vitamin B12, folate, LDH (lactate dehydrogenase), reticulocyte count, and thyroid stimulating hormone (TSH).

Results. The results of the study are in line with the previous studies and showed severe anemia and prevalence among women of reproductive age. Microcyte hypochromic anemia was found to be the most common type of morphological anemia, which was validated with low hemoglobin (Hb) levels, vitamin B12, FT3, and FT4. Additionally, TSH showed a positive correlation with reticulocyte count, LDH, and Hb in Pearson’s correlation test.

Conclusion. The study summarizes the need to investigate the underlying etiological agent responsible for better therapy and management of hypothyroidism and anemia suggesting also the use of oral iron supplements along with levothyroxine therapy.

Abstract

Objective. Pheochromocytomas and paragangliomas are rare neuroendocrine tumors that arise from the chromaffin cells of the adrenal medulla or extra-adrenal tissues. These tumors are characterized by an excessive secretion of catecholamines, which are responsible for the clinical manifestation of the disease. Although most of these tumors are sporadic, underlying genetic abnormalities may be present in up to 24% of the cases. A succinate dehydrogenase subunit B (SDHB) mutation represents one of the rare presentations of the disease. In this study, we represent a rare case of pheochromocytoma associated with SDHB mutation.

Methods. We performed a retrospective review of our case in addition to reviewing the available literature on the same topic.

Results. A 17-year-old patient presented with sustained hypertension. Clinical, laboratory, and radiological evaluations confirmed the diagnosis of catecholamine-secreting tumor. Laparoscopic adrenalectomy was performed. Histopathological and genetic testing confirmed a pheochromocytoma associated with SDHB mutation. No recurrence was detected on two-years of follow up.

Conclusion. Pheochromocytoma associated with SDHB mutation is a rare presentation. Genetic testing for suspecting cases is essential to help to establish the appropriate follow-up plan.

People's driving behavior in Indonesia is very diverse. Some drive in an orderly manner, some drive in a dangerous way. One example that is still often encountered is the use of fast lanes which should be intended for vehicles that want to get ahead of and for vehicles with high speeds. It is still found that driving behavior uses fast lanes by driving the vehicle slowly or not to get ahead of other vehicles. Even though this is very annoying and will affect the driving behavior of other people who both also use fast lanes according to their functions. What is behind the driving behavior and what factors describe the behavior. This study aims to analyze the perceptions and reactions of perpetrators and victims of these driving behaviors. This study used a quantitative descriptive approach and data acquisition was carried out by distributing questionnaires to motorists who drive private cars and drive on the Jakarta-Tangerang Toll Road. The results of the analysis showed similarities that both the perpetrator and the victim felt uncomfortable with slow driving behavior and tended to avoid slow vehicles. However, the perpetrator still abuses the fast lane on the grounds that the road conditions are congested, want to keep their distance, and are not focused. In addition, there are 7 factors that describe slow driving behavior that have similar opinions on the position of respondents as perpetrators and victims.
Perilaku berkendara masyarakat di Indonesia sangatlah beraneka ragam. Ada yang berkendara dengan tertib berlalu lintas, ada juga berkendara dengan cara yang berbahaya. Salah satu contoh yang masih sering ditemui yaitu penggunaan lajur cepat yang semestinya diperuntukan bagi kendaraan yang ingin mendahului dan untuk kendaraan dengan kecepatan tinggi. Masih ditemukan perilaku berkendara yang menggunakan lajur cepat dengan mengemudi kendaraannya lambat atau bukan untuk mendahului kendaraan lain. Padahal ini sangat mengganggu dan akan memengaruhi perilaku berkendara masyarakat lainnya yang sama-sama juga menggunakan lajur cepat sesuai dengan fungsinya. Apa yang melatarbelakangi perilaku berkendara tersebut dan faktor apa saja yang menggambarkan perilaku tersebut. Penelitian ini, bertujuan untuk menganalisis persepsi dan reaksi pelaku maupun korban dari perilaku berkendara tersebut. Penelitian ini menggunakan pendekatan deskriptif kuantitatif dan perolehan data dilakukan dengan penyebaran kuesioner kepada pengendara yang mengemudi mobil pribadi dan berkendara di Jalan Tol Jakarta-Tangerang.

Relevance. Destruction of toxic chemicals is impregnated with hazardous working conditions. In this regard, health monitoring in such workers is subject to more stringent requirements. Occupation-related difficulties in dental care availability cause faster dental health deterioration in the military. This adds relevance to finding and developing modern, rational and effective therapy and prevention measures tailored to specific working conditions the sites of toxic waste destruction.The objective is to evaluate the prevalence and structure of dental diseases and oral cavity disorders in the military exposed to toxic chemicals.Methods. A total of 178 male and female contracted military aged 27-50 years were examined within general medical examination required for admission to work with toxic chemicals. Standard dental methods were used during the examination: interview, visual, physical, and instrumental examinations. Examination data were fed into individual military medical records (form No. 2), as well as into earlier record forms.Results and discussion. Examined patients showed high prevalence of dental diseases (99.4 %), in particular, diseases of dental hard tissues and complicated dental caries. No less than half of the examined (54.5 %) required orthopedic dental treatment. More than 80 % of the examined revealed poor oral hygiene.Conclusion. Considering the high demand (90 %) for sanitation among the military, causing the 25% level of complicated f caries, with average tooth crown destruction score of 0.9 and absence of a staff dentist due to the small size of military units, it is deemed reasonable to involve specialists based on a prior agreed schedule and ensure compliance with developed methods and recommendations.

Relevance. Considering the demand for additional efficient methods among clinicians to assess military mental health, instrumental methods, including psychophysiological and neuropsychological tools, providing objectifying detection of mental disorders (MD) are of particular importance. Event-related potentials (ERP) are a promising additional method of objectification of psychopathological manifestations, allowing to obtain neurophysiological parameters for processes associated with arbitrary attention, identification and decision-making.Objective. The study provides a generalized analysis of contemporary investigations and research outcomes regarding event-related potentials as a diagnostic tool for mental disorders, its diagnostic and prognostic potential in medical examination of military mental disorders.Methods. To assess the ERP diagnostic informative value, we analyzed over 40 scientific studies published within the last 10 years dealing with event-related potentials and their implementation in MDs, various brain structure damages and associated functional disorders. We also summarized the results of applying this method to study patients’ cognitive abilities and integrative functions.Results and discussion. Our analysis of scientific studies shows that the ERP value differs significantly for various MDs, such as: schizophrenic spectrum disorders, affective disorders, or addictive pathology. The conclusion suggests that the assessment of the parameters associated with various ERP modifications can improve objectivity of diagnostic and prognostic outcomes in military mental disorders.Conclusion. Event-related potentials is a promising method of diagnostic significance to assess severity of perception, attention, short-term memory damage, as well as cognitive disorders. ERP can help determine the boundary values and diagnostic criteria, as well as evaluate treatment efficiency and outcomes in military mental disorders. Moreover, ERP could be a promise as an additional research method to objectify MDs in mental state assessment of the military at military medical examination.
