Published: March 2022

Lembaga pendidikan yang bermutu atau berkualitas pasti selalu menganalisis situasi atau keadaan baik diluar atau didalam lembaga itu sendiri. Oleh karena itu kemampuan suatu lembaga untuk menganalisis lingkungan (internal dan eksternal) akan berpengaruh terhadap eksistensi atau kemajuan suatu lembaga pendidikan. Banyak hal yang harus dianalisa, salah satunya lingkungan internal lembaga pendidikan. Lingkungan internal biasanya ada didalam organisasi. Sehingga sangat penting untuk menganalisis lingkungan internal lembaga pendidikan. Dengan demikian lembaga akan mengetahui apa saja yang menjadi kekuatan dan kelemahan. Sehingga lembaga pendidikan dapat merumuskan rencana (action plan) yang tepat.

El legado de la Escuela de Salamanca
Authors: Schwartz Pedro
Published: March 2022

Resumen: La denominación de «Escuela de Economía de Salamanca» para designar importantes contribuciones de los moralistas católicos de los siglos XVI y XVII a la economía política ha hecho fortuna pese a no ser del todo exacta: ni todos estudiaron en la Universidad de Salamanca ni enseñaron exclusivamente en sus aulas. Sería más exacto hablar de ‘las doctrinas económicas de la Escolástica tardía’. No importa. Ese nombre llama la atenciónsobre las contribuciones de un notable grupo de clérigos y seglares que, con sus aciertos y errores, aplicaron los métodos de la filosofía y teología escolástica a los problemas morales planteados por la economía mercantil y financiera del Renacimiento. Sus controversias en materia de formación de los precios, de dinero e inflación, de tipos de cambio e interés, deberían atraer a los economistas actuales, cuyos debates sobre la moral económica pecan a veces de superficiales. Además, podrían servirles para afinar sus instrumentos analíticos, pues un excesivo formalismo a veces les hace olvidar cómo funciona el libre mercado.
Palabras clave: Filosofía Escolástica; ética aristotélica; nominalismo v. realismo; liberalismo económico; oro y plata de las Indias; inflación secular; las dos leyes de Gresham; precio justo; usura e interesse; damnum emergens y lucrum cessans; banqueros de los reyes; comercio internacional; cambio de monedas; teoría cuantitativa; la inflación como impuesto.

Positivism and intrapreneurship: Austrian analysis and alternative
Authors: MARION CEOLIN ARTUR
Published: March 2022

Resumen: El positivismo ha sido una tendencia mayoritaria en las Ciencias Sociales, teniendo un impacto en la intraempresarialidad, que es una actividad creativa y disruptiva que no encaja en los modelos y planificación positivista. El presente artículo trata de entender cómo el Positivismo afecta a la intraempresarialidad y presenta una alternativa basada en la teoría austriaca, utilizando la metodología de explicación en tres partes propuesta por Hayek y posteriormente mejorada por Huerta de Soto. La intraempresarialidad, conceptualizada como innovación dentro de organizaciones existentes, fue afectada por elobjetivismo cuantitativo positivista, dinámica estática, y gestión social. Por otro lado, la teoría austriaca, basada en el subjetivismo y agudeza y juicio empresarial, otorga una aproximación teórica más apropiada a la cuestión – haciendo posible su desencadenamiento hacia las habilidades corporativas necesarias para desarrollar un ambiente intraempresarial: adaptabilidad; descentralización de estructuras, estratégicas entendidas como un proceso, y de cultura organizacional entendidas como resultado de las interacciones sociales dentro de una organización.

Published: March 2022

Resumen: Este artículo revisa y discute las observaciones del profesor Maxi Nieto sobre algunos temas importantes de la moderna teoría del socialismo. En particular, su interpretación del argumento contra la «posibilidad» del cálculo económico sin derechos de propiedad privada desarrollado por la nueva generación de autores de la escuela austriaca. Centra la atención en cuestiones metodológicas para resaltar las deficiencias teóricas de algunas de las principales ideas defendidas por Nieto. También analiza su propuesta del ciber-comunismo como alternativa para superar el desafío del cálculo económico a través de las nuevas tecnologías de la información y la comunicación. Argumenta que su análisis es superficial y que el desafío de los austriacos sobre la imposibilidad del socialismo sigue siendo sólido.

Published: March 2022

En materia de inclusión en Educación Física (EF), la actitud del alumnado sin discapacidad repercute en la per- cepción del alumnado con discapacidad sobre su propia inclusión. Esta actitud está influenciada por factores personales como el sexo, la edad y la experiencia previa, pero no existen instrumentos que valoren diferencias sobre cómo varía en función del tipo de discapacidad. El objetivo de este estudio fue elaborar y validar dos cuestionarios para comparar las actitudes del alumnado de secundaria hacia dos tipos diferentes de discapa- cidad, la visual (CAIPE-Vi) y la intelectual (CAIPE-In). La validez de contenido fue estudiada mediante el juicio de expertos, mientras que la validez de constructo y la fiabilidad se obtuvieron a través del análisis factorial y el alfa de Cronbach. En total, 209 participantes respondieron al CAIPE-Vi (n = 100, 47 chicos y 53 chicas, 14,30 [1,38] años) y al CAIPE-In (n = 109, 53 chicos y 56 chicas, 14,40 [1,40] años). Ambos cuestionarios mostraron una misma estructura bifactorial de siete ítems que explicó el 71,64% de la varianza del CAIPE-Vi y el 65,97% del CAIPE-In, y obtuvo un alfa ordinal superior a 0,70 para cada factor. En conclusión, el CAIPE-Vi y el CAIPE-In han mostrado ser dos instrumentos válidos y fiables para evaluar la actitud del alumnado teniendo en cuenta el tipo de discapacidad. El uso de estos cuestionarios permite obtener información más concreta y desarrollar intervenciones y recursos adecuados que favorezcan la inclusión de alumnado con discapacidad en las clases de EF.

Published: March 2022

The Galang-Galang River or also known as the Binanga Karaeng River is a border river between the Polewali Mandar Regency (Polman) which was formerly known as Polmas before separating from South Sulawesi Province. During the rainy season, the water in this river often overflows and can even pose a danger to plantation and rice field farmers around the two border areas. Some of the rainwater that falls on the surface erodes the soil so that it is carried by the flow of water into the river downstream to make the sediment deposits increase. Sediment formed in the flow of the Galang - Galang river will cause a lack of river capacity during the dry season and in the rainy season, it will cause flooding. In this study, direct measurements and sampling of bottom sediment and floating sediment were carried out at three river points. The purpose of the study was to analyze deductions of basic sedimentary transports and sediments floating in the galange-Galang river. The study conducted direct measurements as well as retrieval of basic sedimentary samples and sediment rising at three points of the river. Basic sedimentary transport was calculated using the van rjin method, and for levitating sediments, it was calculated by a momentary method. From the results of the analysis, the bottom sediment transport discharge in the upstream is 4x10-4 tons/day, in the middle, it is 0.0891 tons/day, and in the downstream, it is 1x10-4 tons/day. Meanwhile, the floating sediment transport discharge is 0.208 tons/day upstream, 0.278 tons/day in the middle, and 0.121 tons/day downstream, where floating sediment transport is measured at a very small discharge so that the results are obtained are also small.

Management of segmental mandibulectomy defects present a major challenge to the rehabilitation team. Mandibular discontinuity obliterates the equilibrium and mandibular function’s symmetry, which leads to altered mandibular movements, facial disFigurement, incomprehensible swallowing, impaired speech and deviation of the remaining fragment towards the surgical side. While opening the mouth, this deviation intensifies, leading to the opening and closing in the angular pathway. A definitive mandibular guiding flange prosthesis on the resected side can be used productively to stabilize the occlusion and correct the deviation. A new prospective for treating segmental mandibulectomy patients by using only one device both for Physiotherapy and Mastication. Keywords: flange prosthesis; mandibular defects; mandibular resection; hemimandibulectomy.

Since the discovery of X-rays and its first use in imaging of a hand, bone tissue has been the chapter of interest in medical imaging. However, X-ray imaging poses limitations nowadays owing to the augmented complexity of implant scaffolds as well as with the advances in bone engineering. As a result, advanced follow-up imaging techniques are of paramount necessity for effective postoperative characterization. Moreover, it is also needed to search for non-invasive, high-sensitivity, and high-resolution structural, functional, and molecular imaging techniques such as acoustic, optical, magnetic, X-Ray, electron, ultrasound, and nuclear imaging, etc. as an alternative to normally used X-ray computed tomography. Further, enthusiastic preclinical scanners have turned out to be accessible, with sensitivity and resolution even superior to clinical scanners, as a consequence helping a rapid transformation from preclinical to clinical applications. Besides, recently, bone-specific probes and contrast agents are developing for better imaging tools in bone-tissue engineering applications. This review highlights such emerging preclinical imaging tools, each with its individual potencies and flaws, either used only or in combination. In particular, multimodal imaging will significantly add to improve the present understanding in the characterization of bone regenerative processes.

Introduced more than 100 years ago by William Einthoven, Electrocardiograms (EKG) remain an essential tool for doctors in diagnosing a variety of conditions. An abnormal EKG remains part of the criteria for diagnosing and activating the response for ST-Elevation Myocardial Infarction (STEMI), one of the most important causes of mortality nationwide [1]. Interpretation of EKGs is an essential tool for any physician, especially in the field of internal medicine, often one of the first lines of defense for diagnosing EKG abnormalities. It is a skill that is learned during medical school and residency training [2]. Despite this, the diagnosis of life-threatening pathology on EKG remains suboptimal in trainees [3]. This poor performance may be attributed to a lack of a standard methodology of teaching EKGs across the United States [3]. Also, with the introduction of computerized interpretation, this may have led to over-reliance on automated readings and less effort to interpret and teach EKGs [4].

Adrenal tumors are very common in medical practice, including a wide spectrum of etiologies. Although most of them are adenomas, infrequent lesions can become a diagnostic and therapeutic challenge for clinicians. Here we present two atypical cases of non-adenomas adrenal tumors with specific imaging, biochemical profile, and surgical resolution. The first case is a 54-year-old woman with a history of hypertension and type 2 diabetes, with an incidentally discovered 7 cm adrenal mass on CT, compatible with a myelolipoma. Biochemical work-up was remarkable for hypersecretion of both cortisol and aldosterone. She underwent laparoscopic adrenalectomy. During follow-up, biochemical cure of hormonal hypersecretion was confirmed. The second case is a 44-year-old woman in whom a 7 cm left non-adenoma adrenal mass was diagnosed incidentally by magnetic resonance. Complete hormonal screening was normal. Laparoscopic adrenalectomy was performed. Biopsy informed a solid neoplasm separated from normal adrenal tissue, with immunohistochemistry compatible with a Schwannoma. These case vignettes describe atypical adrenal cases that should be considered in the differential diagnosis of non-adenomas adrenal tumors. They represent uncommon presentations and illustrate the importance of an appropriate multidisciplinary evaluation of adrenal tumors, in order to improve the surgical and clinicalmanagement of these patients. Keywords: adrenal incidentaloma; adrenal tumor; adrenal myelolipoma; adrenal schwannoma.

Stereolithographic models are three-dimensional reproductions of digital data, created using CAD-CAM software. In recent years, the use of these three-dimensional models has increased as an aid in orthodontic diagnostics and in the planning of oral and maxillofacial surgery [1]. Unlike conventional diagnostic imaging techniques, such as Orthopanoramic radiographs and Cone-Beam CT (CBCT), which provide valuable digital information on bone size and geometry, stereolithographic models exhibit a physical three-dimensional reproduction of the anatomical area of interest with maximum accuracy. These truly guide both the diagnosis process and the surgical operation itself, in order to improve preoperative planning and minimize operative and postoperative morbidity. For the reproduction of these models, a CBCT scan is necessary. Through a 3D printing software, the data is converted into a stereolithographic model in scale. It is produced with transparent resin for better visualization of the bone structures and internal anatomical structures involved, such as the path of the inferior alveolar nerve or, as in this case report, the presence of dental elements totally impacted in the bone [2,3]. The use of these three-dimensional models has demonstrated a series of advantages such as a more accurate planning both orthodontic and surgical treatment, a significant reduction of operating times, a reduction in the time of exposure of the wound, better communication with colleagues and patients and more predictable surgical results [1]. Toothimpaction is defined as the failed eruption of a tooth, which remains embedded in the maxillary or mandibular bone after its period of physiological eruption. It can be partial or total and it most commonly happensto third molars, especially mandibular wisdom teeth, followed by the maxillary canines. Unlike the third molars, the maxillary canines constitute dental elements of great functional importance. They play agreat role of control in the movements of mandibular excursion. According to the classification of included maxillary canines by Yamamoto et al. there are 7 types (Figure 1), with the first three types showing more predictable results in the surgical orthodontic treatment and the following four types considered untreatable with orthodontic anchorage [4].

Hair loss is a very serious problem that men and women struggle with almost every day. Given that many people suffer from this disease, scientists try to find optimal solutions every year. There are many products and methods that claim to restore hair growth or reduce hair loss. Some of these methods seem to be almost completely useless, while others make significant changes. Fortunately, there are many inventions within the field of hair restoration in recent years. Nowadays, many hair loss treatments are available, and therefore the hottest ones are Mesotherapy and PRP. Both these treatments have completely modified the planet of hair loss treatments. Both methods are approved by the World Health Organization. PRP and mesotherapy are among the tried and tested methods of hair restoration which will make an enormous difference. It is not uncommon to mistake these two hair restoration methods, many people make this mistake. However, knowing the difference between PRP and mesotherapy will assist you opt which option is best for you. Because, although both try to repair hair, their performance is slightly different. Therefore, one of these methods may help you to get better results according to your individual characteristics. Although these two treatments have proven effective, people are often confused about choosing one. Each therapy has its pros and cons, so we’ve administered a comparison of mesotherapy vs PRP for hair.

A 17-year-old primigravida developed acute onset postpartum pleuritic chest pain following a prolonged second stage. The clinical syndrome rapidly progressed to chest, neck and facial swelling. Clinical evaluation in parallel with urgent investigations led to the diagnosis of Hamman syndrome, a rare though important benign cause of postpartum chest pain and shortness of breath. Conservative management consisting of close observation, supplemental oxygen, analgesia and reassurance lead to complete resolution of signs and symptoms by the third postpartum day.

A 24 year old woman presented to our institution with a two week history of multiple discrete, painful, nodular and indurated foci of erythema on her lower limbs against a six week background history of a constellation of more nonspecific symptoms including intermittent dry cough, malaise, migrating arthralgias, subjective fevers, anorexia and weight loss. She denied B symptoms. There were no ophthalmic, neurological or cardiovascular symptoms. Examination was significant for features of mild hyper-metabolism manifest by low grade pyrexia with accompanying diaphoresis in conjunction with bilateral lower limb predominant erythema nodosum. Laboratory studies revealed a neutrophilic leucocytosis, raised acute phase reactants/ inflammatory markers, normal serum calcium, ACE, Vitamin D, renal and liver indices. Chest radiography revealed bilateral hilar adenopathy with minimal interstitial involvement. A diagnosis of Löfgren’s syndrome was suspected, an uncommon variant of multisystem sarcoidosis. Subsequent bronchoscopy with trans-bronchial tissue biopsy revealed non-caseating granulomas. The diagnosis was confirmed and treatment instituted with non-steroidal anti-inflammatory medication.

Background: Emotional neglects is the mostly widespread type of childhood experience which is believed to affect the overall psychological adjustment of the child as a result, victims may experience psychological distress with symptoms of low self-esteem, depression and anxiety. There is limited published data on this subject in Tanzania. This study investigates emotional neglect as a risk factor for psychological distress among adolescents in Dar es salaam, Tanzania. Methods: This was a cross-sectional, community-based study of adolescents that was conducted in randomly selected schools in Dar es salaam, Tanzania. The data collection process started July 2019 and was completed in July 2020. Each participant was contacted and informed about the purpose of the research, confidentiality issues, and reporting of the results. A multistage cluster sampling technique was employed to obtain a required number of the study participants. Kessler psychological distress scale (K10) and the Adverse Childhood Experience (ACE) questionnaires were used to measure the variables under this study. Results: Out of 3193 participants enrolled in the study, 1543(48.3%) participants were male and 1650(51.7%) were female. The participants’ age ranged from 13 to 18 years old (mean ± standard deviation= 16.44 ± 2.58 years). Childhood emotional neglect was reported in 51.9% of participants. There was a strong positive correlation between childhood emotional neglect and psychological distress during adolescence (r= 0.55, p<0.001). Conclusion: Finding from this study demonstrated that childhood emotional neglect is prevalent in our setting and is associated with psychological distress during adolescence. Urgent intervention targeting at reducing occurrence of childhood psychological maltreatment is necessary to reduce the incidence of psychological distress among Tanzanian adolescents.

X-linked myotubular myopathy, a rare disorder is part of a group of congenital myopathies that present in the neonatal period. While the clinical presentation in the antenatal period may be varied, the postnatal presentation is of a delayed cry, hypotonia and weakness resembling fetal hypoxia and acidosis. The presence of such features without any factors predisposing towards hypoxia, or a recurring phenotype should prompt a detailed evaluation of the neonate, including genetic evaluation in selected cases. A genetic diagnosis will also aid in evaluation of family members, including an early prenatal diagnosis in future siblings. Keywords: X-linked myotubular myopathy; MTM1; prenatal diagnosis.

Long QT Syndrome (LQTS) can present in the neonate with bradycardia and AV block and confers significant risk for life threatening ventricular arrhythmias. We report a case of a neonate presenting with complex bradyarrhythmias secondary to acquired LQTS after maternal overdose of QT-prolonging medications (haloperidol and sertraline). When the mother was brought in to the delivery center unconscious, fetal bradycardia was noted and the baby was emergently delivered prematurely. The newborn’s initial ECG showed bradycardia with AV node conduction block, rate related His-Purkinje conduction aberration with varying QRS morphology and a QTc >600 ms. She continued to be bradycardic through her first day of life with echocardiogram showing mild cardiac dysfunction. With the elimination of the offending medication from her circulation, the infant’s rate and function abnormalities resolved and QTc normalized. Both haloperidol and sertraline are known to be strong suppressors of the HERG potassium channel that plays an important role in myocardial repolarization and both medications can cross the placenta. Maternal overdose can cause transient QT-prolonging effect similar to that of inherited LQTS type 2. Given the high risk for sudden death in affected newborns, reporting this case is aimed to raise the awareness of acquired LQTS by placental transfer of medication. Early identification of neonates at risk should prompt ECG testing. If long QT is identified, the newborn should be closely monitored with care to avoid any further QT prolonging medications or conditions, until the toxic medication effect resolves.

Purpose: Unprotected sex in men who have sex with men is considered the main current mechanism of HIV infection in Westernculture countries. Chemsex refers to the use of different drugs and substances before or during sexual activities to enhance the sexual experience. Men who have sex with men are a population at risk for chemsex practices and chemsex has also been associated with an altered perception of risk, which leads to increased risk of sexually transmitted diseases, such as HIV. Cariprazine, a novel antipsychotic agent has shown promising results in animal models of substance abuse. Design/methodology/approach: We present three patients diagnosed with VIH and chemsex practices who received off-label treatment with cariprazine in addition to their usual medication regimens. Findings: All of the patients showed an improvement in the risk domain of the Maudsley Addiction Profile, a brief interviewer-administered questionnaire that assesses behavioral aspects in patients with substance abuse. None of them referred side effects. Research limitations/implications - Cariprazine could be a therapeutic weapon for the treatment of HIV patients who engage in chemsex practices. Originality/value - This is the first study to examine the off-label use of cariprazine in a population of HIV and chemsex users’ patients. Keywords: HIV; chemsex; slamming; MSM; cariprazine; maudsley addiction Profile.
