A pilot plant scale of Yellow Konjac (Amorphophallus muelleri Blume) flour production by a centrifugal mill using response surface methodology
Authors: Witoyo Jatmiko Eko , Argo Bambang Dwi , Yuwono Sudarminto Setyo , Widjanarko Simon Bambang
Published: March 2021

This study aimed at investigating the effects of polishing conditions on the physicochemical properties of polished yellow konjac flour (PYKF) with a centrifugal mill using Central Composite Design-Response Surface Methodology (CCD-RSM). Micro-mill milled yellow konjac flour (MMYKF) mass and polishing cycles were the independent variables, with four observed responses (calcium oxalate, viscosity, degree of whiteness (DoW), and glucomannan). The lower limit (-1) and upper limit (+1) for MMYKF mass in this study are 10 and 15 kg, respectively, while the -1 and +1 for the polishing cycle are three times, and seven times, respectively. The optimum prediction occurred at 10 kg of MMYKF mass and six times the polishing cycle with the following characteristics: 0.52 ±0.00% w.b. calcium oxalate, 20362.00 ±16.00 cP viscosity, 62.22 ±0.01 DoW, and 69.43 ±0.02% d.b. glucomannan content, which agreed with the verification data with p-value >0.05 for all observed responses using the paired T-test. Polishing using a centrifugal mill is feasible and promises to be scaled up to industrial scale for yellow konjac flour polishing before the wet extraction process.

Announcement Effects of Unconventional Monetary Policies on Portfolio Flows to Hong Kong
Authors: Lam Rex
Published: March 2021

As the Federal Reserve continues its bond purchases to support the economy, the spillover effects created by unconventional monetary policies in the U.S. have garnered more attention. In particular, there is a need to better understand hot money and to determine whether unconventional bond purchases have played a role in increasing capital flows to emerging markets. Since former Federal Reserve Chairman Ben Bernanke’s testimony, weekly equity fund flow out of emerging markets has averaged a staggering $3.4 billion 1. Although it is unclear whether such rapid outflow has negative consequences on economies, policymakers must make every effort to end unconventional purchases with minimal damage on the financial stability of the global economy. As an important financial center in the Asia Pacific region, Hong Kong is an interesting case to study because of its currency peg to the USD and the possibility that investors use Hong Kong as an entry point to China and other emerging and developing economies in that region. If the latter point were true, examining portfolio flows to Hong Kong would be an essential step towards understanding whether unconventional monetary policies have changed the nature of portfolio flows to emerging markets in Asia and whether these flows have brought about booms in local markets.
A Racist Little Hat: The MSG Debate and American Culture
Authors: Germain Thomas
Published: March 2021

Stop for a moment and ask yourself what you know about monosodium glutamate. If you’re anything like most Americans, your thoughts on the subject are probably simple: MSG is an artificial flavoring most often used with Chinese food, which should be avoided because it’s bad for you and gives you headaches. If this is your thinking, you’re not alone. For the past fifty years, this has been the conventional American understanding of MSG. But times change.

Recently, a vocal movement has sprung up that advocates for an end to the stigma surrounding MSG, as detailed in a Buzzfeed article by John Mahoney titled, “The Notorious MSG’s Unlikely Formula For Success.” Mahoney suggests that a new cultural context is emerging, spearheaded by a group of celebrity chefs who take the iconoclastic position that we should reintroduce MSG to our palates. They argue that beyond the merits of its delicious savory flavor, referred to as “umami,” society’s trepidations about the ingredient are based on research born out of stark racism and bad science which have perpetuated a myth about MSG’s toxicity [1]. But the old guard isn’t going quietly, and just as vocal as the pro-MSG camp are those who fear a change to the status quo.
Refiguring the Romantic Body: Chinese Women Pianists in the American Conservatory
Authors: Vardanega Audrey
Published: March 2021

When the twenty-four-year-old pianist Yuja Wang walked on the stage of the Hollywood Bowl in a tight, short orange dress on August 2, 2011 to play the Third Rachmaninoff Piano Concerto under the direction of conductor Lionel Bringuier, Wang’s attire was interpreted as a transgression of normative expectations for classical performers. The Los Angeles Times reviewer Mark Swed described her dress as “so short and so tight that had there been any less of it, the Bowl might have been forced to restrict admission to any music lover under eighteen not accompanied by an adult…had her heels been any higher, walking, to say nothing of her sensitive pedaling, would have been unfeasible” (Swed 2011). The New Criterion reviewer Jay Nordlinger characterized it as “stripper-wear,” raising the question of how perceptions would change if the “pianist sitting before us were not a [tasteless] brash girl…but an antique, venerable Austro-German Meister” (Nordlinger 2011). Both critics’ comments highlight the significance of the body in classical music performances—where Wang’s clothing style or “stripper-wear” heightens the visibility of her body and draws attention to her sexiness, problematizing critics’ expectations for the comportment of the performing body (Ameer 2011).
One Step Forward, Two Steps Back
Authors: Kirkland Caroline Miller
Published: March 2021

Peace efforts in Palestine are continuous and failing. In order to explain the failed peace attempts, experts draw different conclusions. Thomas Getman, member of a private consulting group specializing in international affairs, explains the conflict in terms of Christian Zionism, a religious doctrine prominent in the United States, and its detrimental role in the peace process. While social justice manifests itself in the cultural practices of traditional, mainstream religions, Christian Zionism ignores the rights-based approach to theology, and it perpetuates myths (Getman). Dennis Ross, the principle informant in the Israeli-Arab conflict under the Bush and Clinton administrations, blames a number of factors. He explains, “The lack of public conditioning for peace, the reluctance to acknowledge the legitimacy of the other side’s grievance and needs, the inability to confront comfortable myths, the difficulty of transforming behavior and acknowledging mistakes, the inherent challenges of getting both sides ready to move at the same time, the unwillingness to make choices, and the absence of leadership, especially among Palestinians, are all factors that have made peace difficult to achieve” (Ross 14). Ultimately, Ross says that it is “myths that prevent all sides from seeing reality and adjusting to it” (Ross 14). The failed peace efforts can be better understood by combining the two stances. Due to the stronghold Christian Zionism has held on United States politics, the Christian Zionist narrative has upheld peace talks in Israel-Palestine and disrupted the process.

In the land of Hum
Authors:   Faculty of Humanities, Džemal Bijedić University, Mostar, Velagić Adnan
Published: March 2021

The paper deals with the position of Herzegovina in the Middle Ages. Although the significance and role of the surrounding causes and phenomena have been elaborated, which have undoubtedly influenced the situation of this area in certain periods, the main focus of the paper was placed on the position of Herzegovina within the Bosnian state, to which it belonged during the Middle Ages. However, the pronounced animosity among the Bosnian authorities and the inability of the central authorities to put the situation under control were often the main cause of the struggle against Hum. The foreign forces, especially the Hungarian Empire and the Ottoman Empire, contributed to this, as they supported their state interests for their interests.
Opportunities in the school of Bosnia and Herzegovina for the time of the temporary state organization in the Kingdom of Srba, Croatia and Slovenia
Authors:   Faculty of Philosophy, University of Tuzla, Selimović Sead
Published: March 2021

The school system represents for each country and society one of the most important segments. Because of this, but also a number of other reasons the authorities try to put schools under their control. Through the education of Bosnia and Herzegovina, political, economic, cultural, national and other goals of the ruling political elites were realized. Curricula and curricula eliminated content whose educational goals were in line with the interests of the Austro-Hungarian regime. The ruling elite spread the idea of a "one-tribe nation", striving to create a unique political, economic, educational and cultural space. Teachers who had to respond to the "spirit of time", and curricula and curriculum, had an important place in achieving goals. Significant changes have been made in the group of national subjects (history, geography, Serbian or Croatian language), with emphasis on the history and geography of Serbs, Croats and Slovenians, and works for Serbian school, literature in literature, literature and literature from the Serbian, Croatian or Slovenian literature. The largest number of workbooks were written by authors from Croatia and Serbia, while only a small number were from Bosnia and Herzegovina.

Between deosmanization and balkanization: refugee’s steps of bosniak history
Authors:   Institute of History, University of Sarajevo, Bandžović Safet
Published: March 2021

The past and the present are inseparable, one interprets the other. Many "long-lasting" processes go beyond local frameworks and regional borders. This also applies to the complex "Eastern question", as well as the problem of the deosmanization of the Balkans, whose political geography in the 19th and 20th centuries was exposed to radical overlaps. Wars and persecutions are important factors in the history of Balkan Muslims. In the seventies of the XIX century, they constituted half of the population in the Ottoman part of the Balkans. With war devastation, a considerable part was killed or expelled to Anadolia between 1870 and 1890. The emergent "Turkish islands" in the Balkans after 1878 were increasingly narrowed, or disappeared due to the displacement of Muslims. Multiethnic and religious color of the Balkans disturbed accounts with simple categorizations. The term "balkanization" signified, after the Balkan wars of 1912-1913, "not only the fragmentation of large and powerful political units, but became synonymous with returning tribal, backward, primitive, and barbaric." The Balkanization of "Ottoman Europe" and the violent changes in its ethnic-religious structure led to discontinuity, the erosion of history, as well as fragmentation of the minds of the remaining Muslims and their afflicted communities, the lack of knowledge of the interconnectedness of their fates. The emigration of Bosniaks and other Muslims of different ethnic and linguistic backgrounds from the Balkans to various parts of the Ottoman Empire, and then to Turkey, during the XIX and XX centuries, had a number of consequences.
Tendencia de actividades odontológicas realizadas en atención primaria del Servicio de Salud Valparaíso - San Antonio, chile: 2008 a 2018
Authors: Moraga Aros Lorena , Espinoza Espinoza Sebastián , García Frías Mariela , Cáceres Lillo Dante
Published: March 2021

Introducción: La actual Política de Salud Bucal chilena indica que la atención odontológica está orientada a la promoción y prevención, reforzando la atención odontológica en Atención Primaria de Salud (APS). Se desconoce cómo esta política se ha materializado en el tiempo, pues, a la fecha, no existen estudios que analicen la tendencia de este tipo de actividades. El objetivo de este estudio fue analizar la tendencia de las actividades odontológicas, realizadas en adultos y adultos mayores, en APS del Servicio de Salud Valparaíso - San Antonio (SSVSA). Material y Métodos: Se realizó un estudio ecológico de tipo mixto entre los años 2008-2018, en 8 de las 9 comunas del SSVSA. Se analizó la tendencia del porcentaje de actividades promocionales-preventivas (APP) y de exodoncias utilizando las bases de datos “Resúmenes Estadísticos Mensuales-A09” (REM-A09). Resultados: El 24,53% y 11,36% de las actividades realizadas correspondieron a APP y a exodoncias, respectivamente. El grupo de 20-64 años presentó un mayor porcentaje de APP y un menor porcentaje de exodoncias que el grupo de 65 y más años, en cada una de las comunas. Hubo una tendencia al aumento del porcentaje de APP y a la disminución del porcentaje de exodoncia en la mayoría de las comunas estudiadas. Discusión: La tendencia de las actividades odontológicas realizadas en APS ha evolucionado a lo largo de los años, con diferencias entre comunas del SSVSA. Para poder determinar cuáles son los motivos que explican los resultados encontrados, se sugiere realizar otros estudios enfocados a la gestión odontológica local de APS.
Aporte de un sistema predictivo de contraloría médica en la gestión de licencias médicas electrónicas
Authors: Bernales Bélgica , Bravo Stéphanie , Causa Leonardo , Gómez Najely , Valdés Macarena
Published: March 2021

Introducción: El retraso del procesamiento de las licencias médicas (LMs) representa un problema de salud pública en Chile, considerando que esto afecta el pago del subsidio a las personas destinado a realizar el reposo médico prescrito mientras no se pueda trabajar. El objetivo de este estudio fue explorar las diferencias en el tiempo de procesamiento de las licencias médicas electrónicas (LMEs) evaluadas por contraloría médica (CM) y las evaluadas por un sistema predictivo de contraloría médica (SPCM) basado en redes neuronales artificiales. Materiales y métodos: El tiempo de procesamiento de LMEs procesadas con SPCM fue comparado con el tiempo de procesamiento de LMEs examinadas solo con CM, usando curvas de Kaplan Meier, prueba de log-rank y modelos multivariados de Cox. Resultados: La tasa de procesamiento del SPCM fue entre 1,7 a 5,5 veces más rápida que la tasa de procesamiento de la CM, ajustando por potenciales confusores. Discusión: La implementación del SPCM permitió disminuir el tiempo de procesamiento de las LMEs, beneficiando a los trabajadores afiliados al seguro público.
El ferrocarril en El Salvador: de la ilusión al abandono en una breve cronología (1872-2018)
Authors: Flores-Guzmán Oscar
Published: March 2021

El sistema ferroviario surgió en el salvador como uno de los proyectos más ambiciosos en siglo XIX. Impulsado por el estado salvadoreño y por comerciantes de la época. El primer tramo de vías férreas en el país significó la apertura de la producción agrícola nacional a los mercados regionales, de Europa y EE. UU. Generó grandes transformaciones en todas las esferas de la vida social del país, pero a su vez este fue cohibido por las mismas fuerzas que lo impulsaban. A final de cuentas, terminó con más pena y con la añoranza de “lo que una vez fue”, pero que no resta ni lo más mínimo a su relevancia histórica.
El Arte Taíno
Authors: López Nuila Jaime Alberto
Published: March 2021

Este artículo describe de forma somera el quehacer social y cultural de los pueblos Taínos; sus características particulares muy propias, como lo fueron sobre todo el uso de aros de piedra para sus ofrendas religiosas, a su vez, nos muestra quehaceres de este pueblo como, por ejemplo, su vocación para la agricultura mediante el uso de sistemas relativamente desarrollados que no impidieron su dependencia histórica de la caza y muy especialmente de la pesca. Las probadas experiencias de este pueblo para el uso de la yuca, de la cual ellos sacaban lo que llamaban Cazabi que es el mismo Casabe que hoy consume el pueblo dominicano. Ese cazabi era el pan de los indios Taínos, que luego de Colón se convierte en el pan de las Indias, porque a falta de trigo, importado de España, el colonizador europeo, conocedor acostumbrado al sabor de la yuca lo utiliza con mucha amplitud y con aceptación general. Las plantaciones de yuca eran los conocidos conucos para aquel pueblo originario.
Mitología en las cosmovisiones Izalqueñas: universo simbólico de nahuales y contra nahuales
Authors: Hernández Vásquez Miguel Ángel
Published: March 2021

La mitología es parte fundamental en las cosmovisiones de la especie humana, en donde se ubican la fundación de los pueblos originarios y su desarrollo evolutivo, en el universo simbólico que condensa sus paradigmas. En ese sentido, el presente artículo es parte de los acápites de los hallazgos del trabajo de tesis titulado “Cosmovisiones locales: tradiciones, costumbres y oralitura en las cofradías izalqueñas” para optar al grado de Licenciado en Antropología por la Universidad Tecnológica de El Salvador. Por lo consiguiente, uno de los objetivos específicos fue inferir, a través de la oralitura izalqueña, la presencia de mitos fundacionales y de creación presentes en las cofradías indígenas de Izalco en torno al relativismo lingüístico.
Dicho proceso de tesis de grado se realizó en el periodo comprendido de marzo a noviembre de 2018, en el casco urbano de la ciudad de Izalco, en donde, a través de las siguientes técnicas del método etnográfco el rapport, la entrevista guiada y no dirigida, se realizó el levantamiento de datos cualitativos en sesiones de trabajo con los mayordomos Alonso García, de la cofradía “Padre Eterno”, y don Lipe Pilia Chile, de la cofradía de San Francisco de Asís, así como con Miguel Ángel Palma Gómez, touroperador izalqueño.
El predominio intelectual de los mulatos a fines de la dominación colonial hispana
Authors: Pérez Memén Fernando
Published: March 2021

A fin de garantizar su dominio en Santo Domingo, la corona española, estableció una política racial de valoración y reconocimiento legal del blanco y de subvaloración al indio, el negro, el árabe, el judío, el mestizo y los mulatos. En la segunda mitad del siglo XVIII, en las universidades de Santo Tomás de Aquino, de los dominicos, y la de Santiago de la Paz, de los jesuitas, en la iglesia, las milicias, en las oficinas reales y el comercio, iban penetrando los mulatos y ocupando posiciones de dirección a pesar de la política segregacionista de la corona, lo que preocupaba y atemorizaba a las autoridades españolas, como lo reveló el gobernador Azlor, en un informe secreto al rey sobre que de seguir esto los mulatos en poco tiempo tomarían el poder.

Los niños que calculaban: en situación de riesgo social y de exclusión del aprendizaje matemático
Authors: Muniz Cristiano Alberto , Candray Jeser
Published: March 2021

La búsqueda por la comprensión de la constitución del ser matemático como sujeto que aprende y produce sentidos subjetivos de su capacidad en elaborar conocimientos matemáticos encuentra en la categoría “sujeto que aprende”, de la Teoría de la Subjetividad – TS, un concepto que amplia como profundiza los análisis interpretativos de la constitución matemática de los niños. La TS posibilita la ampliación de la comprensión del fenómeno del aprendizaje matemático más allá del análisis estrictamente cognitivo, de análisis microgenética de las producciones de registros matemáticos, lo que realizamos en las últimas décadas apoyados en la Teoría de los Campos Conceptuales. Apoyados en diálogos producidos en talleres de matemática lúdica y en la conversación con madres sobre sus historias educativas, buscamos sentidos subjetivos en la historia del aprendizaje matemático de cuatro niños en situación de riesgo. Además del diálogo establecido a lo largo de los talleres lúdicos, recolectamos sus producciones matemáticas. Ese registro, sumado a los constantes diálogos en contexto, permitieron el análisis y la explicación de esquemas matemáticos implícitos en esas producciones matemáticas y reflejaron importantes elementos constituidores de los complejos procesos de aprendizaje matemático. Ahora bien, los análisis microgenéticos no fueron suficientes para el develar la compleja dimensión simbólica-emocional de significación de aprendizajes matemáticos por los sujetos. El diálogo de los niños y sus respetivas madres, por medio de conversación videograbada, permitió comprender mejor la naturaleza de las producciones y sus significados más allá de la situación de la actividad lúdica. Este artículo se limita a traer al análisis de uno de esos casos investigados, un niño con deficiencia auditiva y que, por tanto, presenta dificultad en la organización de los algoritmos matemáticos.

Enseñanza de la Estadística con sentido y en contexto a través de la resolución de problemas
Authors: León Gómez Nelly
Published: March 2021

En la actualidad se tiene conciencia de la necesidad de formar ciudadanos estadísticamente cultos, en el sentido de que posean las habilidades y capacidades para manejar eficiente y críticamente la información, comprender la variabilidad de los fenómenos y tomar decisiones inteligentes en situaciones cambiantes e inciertas. Esto requiere una enseñanza de la Estadística con sentido y en contexto. En este artículo iniciamos refiriéndonos a la Estadística como una herramienta para la vida, ostensible en una cultura estadística que abarca: la alfabetización, el razonamiento y el pensamiento estadístico; luego nos detenemos un poco en la conceptualización de la Educación Estadística y en los elementos clave de la enseñanza de esta disciplina, para finalmente concentrarnos en la resolución de problemas como vía para el desarrollo de una cultura estadística. Mediante ejemplos se presentan los niveles de lectura de datos de Curcio, distintos tipos de contextos como los propuestos por Díaz y Poblete y la OCDE y el ciclo investigativo Wild y Pfannkuch. Las conclusiones apuntan a reforzar la investigación sobre la preparación del docente para llevar al aula una enseñanza de la estadística contextualizada y con sentido, que realmente contribuya a la formación de ciudadanos críticos.

A transcrição fonética da fala nem sempre é algo consensual, devido às próprias limitações das ferramentas disponíveis para este fim, como observa Ladefoged (1990). Esse problema se acentua nos casos de fala espontânea. Pretende-se, assim, tecer algumas considerações sobre a problemática da transcrição do Questionário Fonético-Fonológico (QFF) dos Atlas lingüísticos do Brasil. Sabe-se que é quase impossível fazer uma análise acústica de todos os dados do QFF, por questões óbvias, e, além disso, uma transcrição fina talvez dificultasse o acesso aos dados por quem não fosse especialista em Fonética; mas, por outro lado, uma transcrição imprecisa pode levar a erros de interpretação.

With the deepening of reform and opening-up, the economy of China has developed rapidly. In recent years, shared farms have been one of the popular forms for the Chinese government to help the rural areas to shake off poverty. However, despite of many achievements, the business model of traditional shared farms cannot satisfy the growing market demands. Based on the research conducted under a national undergraduate innovation and entrepreneurship program, this paper starts with an analysis of the advantages and disadvantages of traditional shared farms and then proposes a business model that provides customized products and services. The feasibility of the proposed business model is discussed by using the IDIC model and some suggestions are put forth for the optimization of the business model for customized shared farms.
How to Respond to Customer Complaints -from the Perspective of Argument Strength
Authors: Tsao Wen-Chin , Su Fang-Yu
Published: March 2021

In this era of rapid network technology development, more and more people are sharing or receiving complaints about products or companies via online platforms. Related research finds that negative electronic word of mouth is perceived as credible and will have an adverse impact on companies. The purpose of this study is to explore how company response strategies to negative reviews affect corporate image and purchase intention. We aim to provide appropriate processing mechanisms to help companies reduce the damage of negative word-of-mouth. This study used an experimental design method, manipulating the experimental situation so that the subjects had a simulated personal experience with a company. A questionnaire was provided to collect subjects’ opinions. There were 180 valid subjects. We utilized variance analysis to verify the hypotheses. This study had three primary findings: (1) Different response strategies to negative reviews will have different effects on corporate image and purchase intention. Among them, the accommodative strategy is significantly better than the other strategies – defensiveness and no action – for enhancing corporate image and purchase intention. (2) The impact of the response strategy on purchase intention will be moderated by the strength of the reviews’ arguments, especially for accommodative strategies; however, this moderating effect does not occurred with respect to the impact of response strategies on corporate image. (3) Corporate image has a positive impact on purchase intention. Managerial implications for marketing managers are also discussed.

Published: March 2021

Non-additive entropy measures are important for many applications. In this paper, we introduce a quantile-based non-additive entropy measure, based on Tsallis entropy and study their properties. Some relationships of this measure with well-known reliability mea- sures and ageing classes are studied and some characterization results are presented. Also the concept of quantile-based shift independent entropy measures has been introduced and studied various properties.
A rare case of acute pancreatitis: a diagnostic
conundrum and unusual complications

Published: March 2021

A 63-year-old man with a history of recurrent idiopathic acute pancreatitis (AP) was admitted to our surgical ward due to severe abdominal pain. He denied chronic excessive alcohol use. Other typical causes of AP, such as gallstones, hypertriglyceridemia, and trauma, were ruled out. After considering all possible etiologies, the most likely factor producing AP was medication that had been administered to him two weeks before the very first episode of the disease. Medication should always be considered as a possible trigger of AP, especially if the first episode occurs shortly after drug administration and the etiology is unclear. During patient’s hospitalization, laboratory reports revealed significant fluctuations in the serum levels of pancreatic enzymes, which can be attributed to recurrent bacteremia. After the 30-day period of hospitalization and long-lasting antibiotic therapy, he was discharged in a good condition with normal levels of serum pancreatic enzymes.
Persisting bleeding from the duodenal ulcer in patients with occlusion of the celiac trunk: a case report
Authors: Żyluk Andrzej , Zeair Samir , Gabrysz-Trybek Ewa
Published: March 2021

Introduction: Endoscopic measures have continued to be the primary procedures in the management of ulcer bleeding. Nevertheless, in cases of failed endoscopic hemostasis and re-bleedings, endovascular techniques have gradually gained increased acceptance as an alternative to surgery, allowing to avoid surgical intervention in some cases.
Case report: A case of a 42-year-old patient presenting to the authors’ institution with massive bleeding from the duodenal ulcer, sprang from a pathologically enlarged gastroduodenal artery is reported. This vascular anomaly was a consequence of occlusion of the coeliac trunk (Dunbar syndrome), which was shown on an angio-CT scan. In spite of several endoscopic and endovascular measures, as well as three operations, the bleeding persistently recurred (a total of 6 episodes) and the patient eventually died. The article presents details of operative and endovascular treatments. Contemporary trends in management in cases of failed endoscopic interventions and re-bleedings form peptic ulcers are shown in the discussion.
Radiological changes in maxillary sinus
morphology after lateral sinus floor
augmentation
Authors: Shpachynskyi Oleksandr , Didkovskyi Vyacheslav , Kopchak Andrii
Published: March 2021

Background: Restoration of the masticatory function in patients with edentulous posterior maxilla is often challenging due
to the severe atrophy of the alveolar ridges and proximity of the maxillary sinus, resulting in insufficient bone quantity for
implant-supported dentures.

Aim: The purpose of this study was to analyze the changes in Schneiderian membrane thickness after lateral sinus floor augmentation
(LSFA) using cone beam computed tomography (CBCT).

Material and methods: W LSFA procedures using different bone grafting materials were performed in 87 patients, operated
on in two clinical institutions from 2016 to 2018. CBCT examination was performed in all patients before the LSFA procedure,
at 1 month after surgery, and after 6 months, before implant placement or loading.

Results: Minor r adiological changes in mucous membrane morphology were observed preoperatively in 17.1% of patients.
Postoperative CBCT in the early postsurgical period demonstrated that the number of intact non-specific sinuses decreased significantly,
i.e. from 86.7% to 26.7%. The number of cases with local hypertrophia of the mucous membrane increased from 20.3%
to 26.7%. Mucosal thickening was observed in 41.7% vs 7.5%. The number of intact sinuses increased to 57.8%. The number of cases
with local membrane hypertrophia also increased – to 37.4%. The number of cases with mucosal thickening or fluid accumulation
decreased significantly to 11.8 and 5.3% respectively. In 2 cases the development of chronic sinusitis required secondary surgeries.

Conclusion: The present retrospective study revealed that minor radiological changes in the morphology of the maxillary sinus
mucosa were observed preoperatively in 17.1% of patients who underwent LSFA procedures. In the early and late postoperative
period their frequency increased to 68.5% and 47.1%, r espectively. However, the clinical signs o f sinusitis developed only in
19.26% of patients. No significant correlations were found between the frequency and severity of postoperative radiological
changes and residual bone height, sinus anatomy, initial state of the mucous membrane and type of the grafting material.
Trudne drogi adaptacji rodziców wobec głębokiej niepełnosprawności intelektualnej dziecka
Authors: Aksamit Diana , Kruś-Kubaszewska Katarzyna
Published: March 2021

Przeanalizowana zostanie droga rodziców do przystosowania się do głębokiej niepełnosprawności intelektualnej małego dziecka, dziecka starszego i osoby dorosłej. Proces adaptacji do głębokiej niepełnosprawności jest nieodłącznie związany z różnymi emocjami i kryzysem psychicznym całej rodziny. Rozciąga się na całe życie, szczególnie w rodzinach wychowujących dzieci z głębokim stopniem niepełnosprawności. Specjalistyczna literatura naukowa rzadko opisuje sytuację rodzin wychowujących małe dzieci oraz dorosłe osoby z głębokim stopniem niepełnosprawności. Rozważania mają zwrócić uwagę na to, że tylko dogłębne poznanie i przeanalizowanie sposobów adaptacji rodziców może mieć oddźwięk w systemie wsparcia rodzin z małym dzieckiem, może też być przydatne opiekunom dorosłych osób z głęboką niepełnosprawnością w ich funkcjonowaniu psychicznym przez całe życie.
Blogi – nowe forum rodziców dzieci z niepełnosprawnościami
Authors: Palak Zofia
Published: March 2021

Jedną z form mediów społecznościowych są blogi – sieciowe pamiętniki, które funkcjonują tylko w przestrzeni internetowej i podporządkowane są w swojej formie wymogom Internetu. Jest to nowe forum wymiany informacji, a także relacji między ludźmi. Autorami blogów są często również rodzice dzieci z niepełnosprawnościami, którzy w takiej formie dzielą się swoimi doświadczeniami związanymi ze skomplikowanym, trudniejszym rodzicielstwem, poszukując niejednokrotnie pomocy, jakiegoś rodzaju wsparcia, ale i dzieląc się problemami, potrzebami, możliwościami i sukcesami swoich dzieci.
Polskie regulacje dotyczące zapewnienia dostępności dla osób z niepełnosprawnością
Authors: Szeroczyńska Małgorzata
Published: March 2021

W artykule prezentuję ustawę o zapewnianiu dostępności osobom ze szczególnymi potrzebami. Omawiam nie tylko szczegółowo rozwiązania ustawowe już obowiązujące i wchodzące w życie w 2021 r., ale także wskazuję na wdrożone w praktyce do tej pory działania Rady Dostępności i Programu Dostępność Plus. Ukazuję również ryzyko spowolnienia procesu zapewniania dostępności zarówno w ramach działalności publicznej, jak i przede wszystkim w sektorze prywatnym, który nie jest w zasadzie w ogóle zobligowany do przestrzegania przedmiotowej ustawy.
Fremtidens grafikk – Visuelle stiluttrykk i multimodal klimaformidling
Authors: Granly Foss Eirik
Published: March 2021

Organisasjoner, selskaper og institusjoner involverer stadig oftere profesjonelle grafiske designere i sin tekstproduksjon, som skal sørge for at tekstene har et visuelt stiluttrykk som tjener avsenderens interesser. Denne artikkelen benytter et sosialsemiotisk rammeverk influert av kognitiv metaforteori og fenomenologisk filosofi, for å undersøke hvordan form og bevegelse i slike visuelle stiluttrykk brukes i multimodal klimaformidling, og hvordan dette virker inn på framstillingen av klimaendringene. Studiens materiale består av tre digitalt tilgjengelige videoserier, to produsert av Norges rikskringkasting (NRK) og en av Opplysningskontoret for egg og kjøtt, der alle seriene har som formål å formidle påstander om menneskeskapte klimaendringer. Funnene illustrerer hvordan bruken av form og bevegelse knytter samtlige serier til brede ansamlinger av affektivt orienterte menings-potensialer – snarere enn å spisse serienes budskap, har de potensial til å øke grunnlaget for engasjement og gjenkjennelse, og til å assosiere avsender og budskap med ulike presumptivt verdsatte kvaliteter. Implikasjonene av disse funnene drøftes i lys av tidligere forskning i kritisk diskursanalyse, multimodalitet og sakprosa.
