Published: May 2021

Unmanned aerial vehicles (UAVs) are being used in many applications,such as surveillance and product delivery. Currently, manyUAVs are controlled by WiFi or proprietary radio technologies.However, it is envisioned that 5G and beyond 5G (B5G) networkscan connect the UAVs and increase the overall security due to improvedcontrol by operators and governments. Soon, UAVs willalso be used as mobile radio base stations to extend reach or improvethe network capacity. All this motivates intense research on5G technologies for supporting UAV-based applications. However,there are currently few simulation tools for testing and investigatingtelecommunication systems that involve UAV solutions. Forinstance, modern 5G networks use multiple antennas that enablebeamforming. A realistic simulation, in this case, requires not onlysupport for beamforming but also for realistic UAV trajectories,which impact the communication channel evolution over time. Toevaluate scenarios with connected UAVs, this paper presents a toolthat simulates flights in a virtual environment, gathers informationabout the channels among UAVs and the mobile network, andcalculates performance indicators regarding the communicationsystem.

Published: May 2021

The Internet is one of the main ways of interaction, production and consumption of content. The active participation of individuals in this environment, disseminating ideas and defending or proposing political agendas, can be considered as a new form of social mobilization, especially in the current pandemic context in which social distance is recommended. Based on this, this article presents the results of a project that aimed to investigate and learn about popular participation in the administrative sphere through the Internet in the municipalities that make up the Vale do Caí region. To achieve this goal, through exploratory research and a qualitative approach, all available technologies were mapped for citizens to participate in the political life of the 20 municipalities that make up the region from the websites of their prefectures. The analysis of these technologies is essential to understand how the interaction between the government and the citizen occurs in the Vale do Caí region.

Intellectual property protection by incubated companies: Using formal and non-formal methods
Authors: Roncalio Luciano Benvenuti , Richartz Fernando
Published: May 2021

Objective: to verify and characterize the use of formal and non-formal methods to protect intellectual property by incubated companies that operate in the health sector. Methodology/approach: bibliographic research, research with primary sources, and comparative study of the interaction of organizations with the environment. The incubated companies' primary source information was obtained through face-to-face interviews in field research carried out at the Celta incubator, in Florianópolis/SC, Brazil. Main results: there was an intense use of non-formal methods by the companies studied. The literature adequately predicted non-formal methods adopted by companies. It was also identified that regularity in certifications with Anvisa – Brazilian National Health Surveillance Agency, constitutes an important complementary asset for the appropriation of intellectual property (Teece, 1986) for the companies studied. Theoretical/methodological contributions: identification of the use of non-formal methods by companies and their composition of use with formal methods contributes to the advancement of literature and business practice. Relevance/originality: this study emphasized research on the use of non-formal methods to protect intellectual property by incubated companies, a topic little explored in the literature. Social and practical contribution: the use of non-formal methods is of particular interest to small and medium-sized companies because their implementation is under the company's control and, also, because they circumvent the time and costs incurred in the formal registration. It is recommended to expand the understanding concerning the role of complementary assets (Teece, 1986) for technology-based companies.

This paper presents the start-up methodology for a project that leverages the opportunities that social media affords to give teachers voice and agency. In response to negative press about teachers in mainstream media, coupled with research that shows that teachers are working hard to meet student academic and wellbeing needs, the researchers employed the assertive technologies of social media and started a campaign to promote the work of pre-service and in-service teachers. The paper presents the theorising behind the start-up methodology for the social media campaign and outlines a response to an identified opportunity. It argues that social media provides new opportunities for professional connectedness, story sharing and collegial support.

This qualitativestudy investigatesthe changes and continuities in conceptions of teaching and learning from course commencement to course completion for a group of international pre-service teachers undertaking a two-year Masters-level degree in Initial Teacher Education (ITE). Data were collected through a series of graphic elicitation activities and ranking tasks at baseline and endpoint. Findings indicate that there was:a growing emphasis on student engagement and its linkages to student learning; a shift from viewing teaching as the transfer of knowledge to learning as anactive process; and a more developed repertoire of professional language to explain what is valued and why. This study provides valuable insights into international pre-service teachers’ evolving conceptions of teaching and learning. These findings suggest that international pre-service teachersneed many opportunities to interrogate and refine their understanding of teaching and learning and how this appliesto the contexts in which they will teach.
Brain as Transducer: What if the brain is not a self-contained information processor? What if it is simply a transducer?
Authors: Epstein Robert
Published: May 2021

Evolution has not only produced millions of different species; it has also produced millions of different transducers. Our bodies are encased in transducers that convert distinctive properties of electromagnetic radiation, air pressure waves, airborne chemicals, liquid-borne chemicals, textures, pressure, and temperature into similarly distinctive patterns of electrical and chemical activity in the brain. What if, at some point - perhaps when humans first developed language and consciousness - the random mixing of genes produced a brain that could send signals to and receive signals from an alternate universe? Unlike string theory or theories of parallel universes, the theory that the brain is bidirectional transducer is directly testable, and empirical support for this theory has the potential to profoundly change our understanding both of ourselves and of our universe. It will help to explain, in rational and objective terms, more than 50 odd phenomena that have baffled humans for eons, among them: dreams, hallucinations, schizophrenia, and even claims about bizarre experiences such as demonic possession and communication with the dead. Neuroscience has been hamstrung for half a century by its reliance on the information processing model of the brain - a metaphor that has shed no light on how the human brain actually works. Let’s set aside the metaphors we have used for 2,000 years to "explain" human intelligence. Transduction theory is a testable theory consistent with evolutionary theory and with three core theories of modern physics - string theory, inflation theory, and quantum theory - each of which predicts the existence of alternate universes.
ADMINISTRATION SYSTEM FOR END TO END LUXURY APARTMENT MANAGEMENT SOFTWARE
Authors: Joseph Kevin
Published: May 2021

A majority of unpleasant issues faced by landlords and tenants seem to grow due to lack of communication. Late rent payments turns into an eviction. A non-functional AC or a broken window becomes a reason to break a lease. Fortunately, building a positive relationship doesn't take much effort and it all starts with one basic idea: communication.

This project is entitled as “Administration System for end to end luxury apartment management software”, which is a software for managing highly customizable multiple apartments, flat, building or any kind of real estate properties.

The software is to ease property management burdens on small and independent landlords.The challenge was to conceptualize and develop a simple,streamlined managementtool for smaller property owners.The toolneeded tobe able to managemarketing for the property, encourageon-time payments by tenants, keeptrack of transactions, and handle maintenance requests.

The key technologies used for creating the software are HTML, CSS, Bootstrap, JavaScript, Python, MySQL and jQuery.

In this modern world, cognitive behavioral therapy is increasingly becoming a popular psychotherapeutic method amongst other talking therapies. CBT is a short term psychological technique which can help to modify patient’s attitude. It should be considered that CBT is nothing but learning and doing. So it could be impossible without patient’s cooperation. It could be argued that CBT has been identified as a remarkable treatment for considerable numbers of mental diseases specially mood disorders such as depression and anxiety. There are a wide range of arguments for and against Cognitive behavioral therapy. In this framework, firstly, CBT and its principles will be completely introduced. Secondly, application of CBT will be mentioned. Thirdly, some criticism will be expressed. Finally, in this paper, some collusion will be drawn.

Published: May 2021

Fetal mesentric lymphangioma, a congenital fetal abdominal cystic malformation has a rare occurrence. Antenatal detection, its differential diagnosis, prenatal management options and parental counseling regarding postnatal prognosis of such a case are thus rarely discussed. We report two cases of antenatally detected fetal cystic abdominal mass with a provisional diagnosis of abdominal lymphangioma. Postnatally one of the neonates developed features of intestinal obstruction and required surgical intervention. Intra-operative findings and histopathology report confirmed a mesentric lymphangioma. The other neonate had associated subcutaneous lymphangiectasia in left lumbar region, left sided inguinal hernia, undescended testes and was asymptomatic postnatally and managed conservatively.
Nutrient Drinking Test as Biomarker in Functional Dyspepsia
Authors: Scarpellini Emidio , Van den Houte Karen , Schol Jolien , Huang I-Hsuan , Colomier Ester , Carbone Florencia , Tack Jan
Published: May 2021

INTRODUCTION:

Functional dyspepsia (FD) is a prevalent condition with multifactorial pathophysiology, including impaired gastric accommodation (GA), hypersensitivity to gastric distention, and delayed gastric emptying. Drink tests (DT) have been proposed as a potential biomarker for the presence and severity of gastric sensorimotor dysfunction. Thus, we aimed to summarize the state of knowledge on different DT and their potential as a biomarker for FD.

METHODS:

A PubMed and MEDLINE search was conducted for English language articles, reviews, meta-analyses, case series, and randomized controlled trials, including also published meeting abstracts.

RESULTS:

Several DT have been described in literature (e.g., different type of liquid, number of calories used, pace of drinking, and subject's awareness of the amount of liquid drunk). FD patients ingest significantly less volume in the different variants of the tests. The slow nutrient (“satiety drinking”) test (SDT) studies show the most consistent separation between health and FD and correlation with GA. However, sensitivity to distention may be correlated with rapid DT. SDTs were used to evaluate the effect of several pharmacological agents, often showing concordance between their effects on GA and tolerated nutrient volume. This correlation was not found mainly for agents with central actions.

DISCUSSION:

An SDT is a potential diagnostic biomarker in FD, reflecting GA. Additional studies are required to confirm its role as a predictive biomarker for treatment outcome in FD.

Published: May 2021

INTRODUCTION:

Comparative data on scores that predict outcome in primary biliary cholangitis (PBC) are scarce. We aimed to assess and compare the prognostic value of the Mayo Risk Score (MRS, 1989 and 1994), UK-PBC score, and GLOBE score in a large international cohort of patients with PBC.

METHODS:

Ursodeoxycholic acid–treated patients from 7 centers participating in the GLOBAL PBC Study Group were included. The discriminatory performance of the scores was assessed with concordance statistics at yearly intervals up to 5 years. Model for End-stage Liver Disease was included for comparison. Prediction accuracy was assessed by comparing predicted survival and actual survival in Kaplan-Meier analyses.

RESULTS:

A total of 1,100 ursodeoxycholic acid–treated patients with PBC were included, with a mean (SD) age of 53.6 (12.0) years, of whom 1,003 (91%) were female. During a median follow-up of 7.6 (interquartile range 4.1–11.7) years, 42 patients underwent liver transplantation, and 127 patients died. At 1 year, the concordance statistic for Model for End-stage Liver Disease was 0.68 (95% confidence interval [CI] 0.64–0.72), 0.74 (95% CI 0.67–0.80) for the UK-PBC score, 0.76 (95% CI 0.72–0.81) for the MRS (1989 and 1994), and 0.80 (95% CI 0.76–0.84) for the GLOBE score. The GLOBE score showed superior discriminatory performance, but differences were not statistically different. For all scores, discriminatory performance increased in those with bilirubin >0.6 × ULN and advanced fibrosis estimated with Fibrosis-4. The predicted (median) minus observed 5-year transplant-free survival was +0.4% and +2.5% for the MRS (1989) and GLOBE score, respectively.

DISCUSSION:

All prognostic scores developed for PBC (GLOBE, UK-PBC, and MRS) demonstrated comparable discriminating performance for liver transplantation or death as well as good prediction accuracy.

MEJORAMIENTO GENÉTICO DE ALSTROEMERIA EN LA ARGENTINA: OBTENCIÓN DE HÍBRIDOS A TRAVÉS DE RESCATE DE EMBRIONES
Authors: PAKOCA C. , BUGALLO V. , FACCIUTO G.
Published: May 2021

El género Alstroemeria comprende cerca de 90 especies restrictas a América del Sur, de las cuales, 10 se distribuyen en la Argentina. Su cultivo ha crecido en popularidad debido a la variedad de colores y calidad postcosecha de sus ﬂores.

El objetivo de este trabajo fue el estudio de la compatibilidad entre A. psittacina y 9 variedades de alstroemeria y el ajuste de la técnica de rescate de embriones.

El estudio del crecimiento del tubo polínico permitió detectar distintas situaciones según las variedades. El número de embriones germinados y la obtención de plántulas normales varió respecto a la variedad y al tiempo al rescate. En el caso de los cruzamientos con “Belvedere”, la mayor cantidad de embriones germinados se produjo a los 14 días post polinización (DPP), para “Cartagena” a los 7 DPP y para “Costa Azul” no se detectaron diferencias signiﬁcativas entre ambos tiempos. Se obtuvieron plántulas en los cruzamientos con “Belvedere”, “Cartagena”, “Costa Azul”, “Himalaya” y “Virginia”. La eﬁciencia reproductiva mayor fue en “Costa Azul” siendo 6,6 y 8,4 para los rescates a 7 y 14 DPP, respectivamente. Estos resultados permitirán el avance del plan de mejoramiento de Alstroemeria para la obtención de variedades argentinas.
The Effect of Growth and Systematic Risk on the Firmâ€™s Value: Profitability as a Mediating Variable
Authors: Nugroho Mulyanto , Halik Abdul
Published: May 2021

This research aimed to examine the impact of growth and systematic risk on company value, mediated by profitability in insurance companies listed on the Indonesia Stock Exchange (IDX). There are 88 companies in the financial sector in the insurance sub-sector listed on the IDX. They were taken as the population by using the purposive sampling technique. The sample of this study consisted of fourteen insurance companies. The data is analyzed using partial least square structural equation modeling (PLS-SEM). It was found that growth has a significant positive effect on profitability, and profitability has a significant positive effect on firm value. It means that profitability fully mediates the effect of growth on firm value. On the contrary, growth does not have a significant direct effect on firm value. Systematic risk has no significant effect on profitability and firm value. These findings are expected to have a good impact on investors and firmsâ€™ managers in Indonesia by looking at the growth and its impact on current corporate values.

Published: May 2021

The bio-oil produced from pyrolysis of woody biomass typically shows unfavourable characteristics such as high acidity, hence it becomes highly corrosive. An upgrading process, e.g., esterification, is necessary to improve the bio-oil quality prior to its use as a transportation fuel. In this work, the bio-oil was produced through a fast pyrolysis of Sengon wood in a fixed-bed pyrolyser at various temperatures. The characteristics (density, viscosity, total acid number, relative concentration of acetic acid, etc.) of the bio-oil were evaluated. The bio-oil with the highest acidity underwent an esterification catalysed by Indonesian natural zeolites at 70 oC for 0-180 min with a ratio of bio-oil to methanol of 1:3. The catalytic performance of the Indonesian natural zeolites during the esterification was investigated. A significant decrease in the total acid number in the bio-oil was observed, indicating the zeolite catalyst’s good performance. No significant coke formation (0.002-3.704 wt.%) was obtained during the esterification. An interesting phenomenon was observed; a significant decrease in the total acid number was found in the heating up of the bio-oil in the presence of the catalyst but in the absence of methanol. Possibly, other reactions catalysed by the Brønsted and Lewis acids at the zeolite catalyst surface also occurred during the esterification.
Mangrove floristics, forest structure and mapping of Neil Island (Andaman and Nicobar Islands, India) with emphasis on the diversity of Rhizophora species and the significance of small island mangroves
Authors: Kannan Sivakumar , Ragavan P. , Gopalakrishnan K. , Salah Maryam , Balasubramani K.
Published: May 2021

Mangroves in small islands are critical resources for the stability of the island and the livelihood of local coastal communities. However, scientific inventories of mangroves in small islands are rare due to their limited distribution. Considering this, the present study was conducted during 2014–2015 to determine the species composition, biomass, vegetative carbon stock and spatial distribution of mangroves at Neil Island, one of the small islands of the Andaman and Nicobar Islands, India. The spatial locations of different species of mangroves identified from our extensive field surveys were compared with high-resolution images, and the coverage of mangroves (genus level distribution) was interpreted entirely based on the elements of tone and texture. The results show that the mangroves of Neil Island consist of 17 true mangrove species belonging to 12 genera in eight families. The co-existence of all three Indo-West Pacific mangrove species of the genus Rhizophora (Rhizophora apiculata, Rhizophora mucronata and Rhizophora stylosa), and their hybrids (Rhizophora × annamalayana, Rhizophora × lamarckii and Rhizophora × mohanii) shows that this island is a unique place for studying the hybridization and speciation of Rhizophora, a worldwide dominant mangrove genus. Rhizophora mucronata was found to be the dominant species in terms of density, basal area and biomass estimated from forest structural assessments using the quadrat method. The mean density and basal area were 1162 trees ha−1 and 28 m2 ha−1, respectively. The mean above-ground biomass was 271 Mg ha−1, while the mean below-ground biomass was 104 Mg ha−1. The total mean biomass of Neil Island mangroves was 375 Mg ha−1 and its corresponding vegetative carbon stock was 171 Mg C ha−1. The present study provides a practical approach to species-level mapping and assessment to gain site-specific knowledge of the mangroves of Neil Island. Since mangroves are vital for small islands such as Neil Island to cope with rising sea level and increases in natural calamities, the baseline scientific information provided by this study will be beneficial for Integrated Island Management.
Self-Driven Reverse Thermal Engines Under Monotonous and Oscillatory Optimal Operation
Authors: Badescu Viorel
Published: May 2021

The complex time-dependent heat and electromagnetic energy transfer in a new type of reverse thermal engine is analyzed. The reverse thermal engine consists of a cold body, a Peltier element and an electric circuit containing an inductor with controllable inductance. This system allows cooling a body below the ambient temperature. The inductor acts as an accumulator of magnetic energy, receiving electrical work from the Peltier element during some time intervals and supplying the Peltier element with electrical work during other time intervals. The system is named self-driven reverse thermal engine since one of its subsystems (the inductor) receives and releases work. The new type of engine has features which make it different from classical reverse thermal engines: it cannot operate in steady state and it operates for a finite time interval. Instead of usual indicators of performance such as the coefficient of performance, other performance indicators should be used, such as the minimum cooled body temperature and the interval of time needed to reach a given cooled body temperature. Significant cooling effects do not necessarily need high inductance values. The operation of the new engine has been optimized by using direct optimal control procedures. The open-source program package BOCOP has been used to transform the optimal control problem into a non-linear dynamic problem. The minimum temperature reached by the cooled body depends on its mass. There exists, however, a global minimum temperature, for a specified optimum mass of the cooled body. The minimum temperature decreases by increasing the value of the Seebeck coefficient and by decreasing the thermal conductance. Thermal damped oscillations may arise under special circumstances. This implies a very small difference between the initial temperatures of the cold and cooled bodies and a specific range of variation for the conductance of the Peltier element.
Italian wh-questions and the low periphery
Authors: Badan Linda , Crocco Claudia
Published: May 2021

This article deals with Italian questions with a post-verbal wh-element, which are generally defined asin situ. We show that post-verbal wh-questions can be interpreted as information-seeking questions, and provide syntactic arguments supporting the hypothesis that the post-verbal wh-element is only apparentlyin situ. We claim that, in certain contexts, the post-verbal wh-element undergoes a syntactic movement targeting a low-peripheral focus position dedicated to the expression of informational focus. We integrate our analysis with the examination of a number of cases of low-peripheral wh-elements from the CLIPS and LIP corpora of spoken Italian. As for prosody, the available data show that a sentence-final wh-element carries the nuclear accent of the utterance. Moreover, low-peripheral wh-questions seem pragmatically more restricted compared to their counterparts with a fronted wh-. Although further investigation may reveal additional contexts for the questions at stake, low-peripheral wh-questions need to be linked to the preceding discourse context and can be used to add emphasis to the missing piece of information represented by the wh-element.

Our low-peripheral analysis complements the current left-peripheral analysis of Italian wh-questions: wh-elements in left and low periphery display different interpretive and prosodic properties, indicating that they are involved in different phenomena. The results of this study also support the view that the low periphery is more subject to pragmatic restrictions compared to the left periphery.
Vers une sémiotique sadienne
Authors: Torres-Martínez Sergio
Published: May 2021

La présente étude aborde la question de savoir comment l’œuvre du Marquis de Sade reste sur les développements des jeux du langage wittgensteniens, c’est-à-dire des pratiques langagières associées à la communication dans un contexte donné. Tout d’abord, une identification de la règle (en tant qu’élément organique d’une pratique langagière), et du rôle de l’abduction peircienne pour son application, montre que pour Sade « faire la même chose » (c’est-à-dire suivre la règle) lui permet de créer un système sémiotique pour justifier une idéologie du privilège bourgeois. Ainsi conçue, la règle d’auteur devient expérience iconique d’hypervisibilité (fondée sur la frontalité de la sexualité) lorsqu’elle est appliquée par le lecteur (participant potentiel) à des nouveaux jeux du langage. En ce sens, les jeux du langage proposés par Sade visent à franchir les rets du livre pour justifier les illusions (im)morales de l’auteur, clés de voûte de toute son œuvre.
L’ innovation en santé est-elle perçue comme étant technologique ou sociale? Une réflexion conceptuelle dans le domaine de la santé publique
Authors: Niang Marietou , Dupéré Sophie , Gagnon Marie-Pierre
Published: May 2021

Les innovations en santé se produisent dans différents services, organisations et communautés.De plus, elles font face à de multiples logiques institutionnelles, qui sont souvent contradictoires. La logique du marché axée principalement sur la rentabilité et sur la création de la valeur économique à travers les innovations détient le monopole dans les systèmes d’innovation actuels. Cette orientation s’appuie sur une vision techno-économique de l’innovation, selon laquelle les technologies sont considérées comme une fin en soi. Par conséquent, la valeur économique de l’innovation est privilégiée par rapport à sa valeur sociale. Cette perspective dominante comporte différents défis et enjeux dans le domaine de la santé publique et communautaire, où maints acteurs concourent et ont des intérêts divergents. Cet article s’intéresse de près à la notion d’innovation dans le but de clarifier sa signification et de repenser ses différentes orientations paradigmatiques, notamment techno-économique et sociale. La discussion portera sur l’intérêt de l’innovation sociale comme paradigme à promouvoir dans le domaine de la santé publique.

L’objectif du présent travail est d’identifier les stratégies développées par les femmes entrepreneures engagées dans les microentreprises et de vérifier si celles-ci constituent des innovations sociales ou de simples stratégies. Pour ce faire, des récits de vie ont été recueillis, pendant la période du confinement pandémique, notamment au mois d’avril 2020. L’analyse de ces récits a montré que les stratégies mises en place par ces femmes sont ambidextres, c’est-à-dire qu’elles associent aussi bien les stratégies d’exploitation que d’exploration. Les stratégies d’exploitation portent sur les déplacements, sur la flexibilité dans la gestion de la main-d’oeuvre et sur l’ajustement des jours et des horaires de travail afin de maintenir un certain niveau d’activité en pleine crise pandémique. Les secondes stratégies d’exploration, quant à elles, portent sur la recherche d’une nouvelle clientèle et sur le développement de nouveaux produits pendant cette période. Les critères de Bund et ses collaborateurs (2013) permettent de montrer que les objectifs visés par les stratégies d’exploration constituent bien des innovations sociales. Enfin, ces résultats ont des implications sur les stratégies d’adaptation et de survie des microentreprises des femmes en période de crise.

Le paiement mobile apparait comme une solution idéale dans cette période de lutte mondiale contre la pandémie de COVID-19. Cependant, plus de la moitié des Ivoiriens (soit 53,13 %) continuent d’être réticents à l’utilisation du paiement mobile. Dans cette perspective, cette recherche explore les déterminants de l’utilisation du paiement mobile et de leur influence sur l’intention d’utilisation. L’influence de ces facteurs a été testée à l’aide d’un modèle d’équations structurelles sur un échantillon de 250 Ivoiriens. Les résultats montrent que la confiance et la facilité d’utilisation influencent positivement l’intention des Ivoiriens d’utiliser le paiement mobile. Quant à la sécurité perçue, une bonne perception de la sécurité n’a aucune influence sur l’intention d’utilisation, tandis qu’une mauvaise perception de la sécurité influence négativement l’intention d’utilisation.

The Covid-19 pandemic is a global pandemic that has a big impact to conditions of a country. However, in a country, sometimes there is a difference in the influence of the Covid-19 pandemic on one region to another. This study aims to analyze the impact of the Covid-19 pandemic on the economic performance of provinces in Indonesia. The method used in this research is the descriptive statistical method using secondary data from the Central Bureau of Statistics, related ministries, previous research, and other internet sources. The analysis found 1) the Covid-19 pandemic had a negative impact on the variables of economic growth, unemployment, poverty, and inequality; 2) The Covid-19 pandemic affected economic conditions through the implementation of large-scale social restrictions (PSBB) with the consequence of limiting the space/activities of the community so that the economic process was hampered. 3) The Covid 19 pandemic has a greater impact on provinces with high mobility and a high population, where these characteristics are mostly owned by provinces on the island of Java

Background and Aims: Nonalcoholic fatty liver disease (NAFLD) and sarcopenic obesity share several pathophysiologic backgrounds. No prior studies have determined a plausible association between sarcopenic obesity and NAFLD and NAFLD-associated fibrosis. We aim to investigate the association between sarcopenic obesity and NAFLD, and NAFLD-associated fibrosis detected by transient elastography.

Methods: In a cross-sectional study from the 2017-2018 National Health and Nutrition Examination Survey, 1,925 participants were identified. NAFLD was defined by controlled attenuation parameter (CAP) scores and significant fibrosis (≥F2)/cirrhosis by liver stiffness measurements on transient elastography. Sarcopenic obesity was defined by appendicular lean mass and body fat.

Results: Individuals with sarcopenic obesity had a significantly higher odds of having NAFLD [CAP score ≥263 dB/m, odds ratio (OR): 2.88, 95% confidence interval (CI): 1.82-4.57, and CAP score ≥285, OR: 3.71, 95%CI: 2.24-6.14] after adjusting for age, gender, and race/ethnicity. The association remained statistically significant after adjustment for socioeconomic status, lifestyle and behavioral risk factors, and metabolic conditions (CAP score ≥263, OR: 2.61, 95%CI: 1.51-4.50, and CAP score ≥285, OR: 3.31, 95%CI: 1.85-5.96). Sarcopenic obesity was also associated with higher odds of having NAFLD-associated significant fibrosis (OR 2.22, 95% CI: 1.03-4.80) in the multivariate model. While those with sarcopenic obesity had a higher prevalence of NAFLD-associated cirrhosis, this association did not reach statistical significance.

Conclusions: Sarcopenic obesity was independently associated with an increased risk of NAFLD and NAFLD- associated significant fibrosis independent of well-defined risk factors. Targeted interventions to improve sarcopenic obesity may reduce the risk of NAFLD and NAFLD-associated siginificant fibrosis.

Home is a space for the seeds of democracy to grow. Democracy in the family matures the democratic process in society and the state. A democraticperson in  family is a democratic cittizen in state life. The purpose of this paper is to explore democratic values in the family as a place for the development of democracy at the state level, and how the shift in democracy at the family level occurs due to the presence of digital technology which distorts communication, relationships, and the value of equality. The description in this paper comes to the conclusion that there is a good side to democracy in a family that grows above physical and emotional relationships, direct and face-to-face relationships. The facts that occur in today's families, the breakdown, estrangement, and disharmony in today's families, one of which is triggered by the lack of direct communication due to excessive entry of digital technology.Keywords: Democracy; Family; Communication; Digital Technology AbstrakTulisan ini bertolak dari kemunduran nilai-nilai demokrasi di dalam seperti kesetaraan, kejujuran, keterbukaan, kebebasan, akibat intervensi teknologi digital. Asumsi dasar tulisan ini adalah bahwa demokrasi yang dikenal publik pun diterima dan berakar kuat dalam keluarga. Keluarga adalah tempat pertama kali seorang mengenal demokrasi. Rumah adalah ruang bagi bertumbuhnya bibit-bibit demokrasi. Demokrasi dalam keluarga mematangkan proses demokrasi dalam masyarakat dan negara. Seorang yang demokratis dalam keluarga berarti demokratis dalam kehidupan negara. Tujuan penulisan ini adalah untuk mengeksplorasi nilai-nilai demokrasi dalam keluarga sebagai tempat bertumbuh-kembangnya demokrasi di tingkat negara, dan bagaimana pergeseran demokrasi pada tataran keluarga terjadi akibat kehadiran teknologi digital yang mendistorsi komunikasi, relasi, dan nilai kesetaraan. Uraian dalam tulisan ini sampai pada kesimpulan bahwa terdapat sisi baik demokrasi dalam keluarga bertumbuh di atas hubungan fisik dan emosi, hubungan langsung dan tatap muka. Fakta yang terjadi pada keluarga-keluarga masa kini, keretakan, kerenggangan, dan disharmonisasi dalam keluarga-keluarga masa kini, salah satunya dipicu oleh kurangnya komunikasi langsung akibat masuknya teknologi digital yang berlebihan.Kata Kunci: Demokrasi; Keluarga; Komunikasi; Teknologi Digital

Ideally, an interpretation that uses the tahlili method in classical interpretation is comprehensive and can produce human problems. But in fact, the interpretation of this model does not touch human issues. Instead, it tends to be rigid and very fixated on the text. This study aims to determine the maudhu'i (thematic) method of Hassan Hanafi in his work al-Din wa al-Tsaurah. This study seeks to answer the orientation of the interpretation of the al-Qur'an Hassan Hanafi towards the people's revolutionary movement. By using the content analysis method, namely by analyzing and processing messages or a tool to observe and analyze the content of open communication behavior of the selected research object. The results showed that the characteristics of Hassan Hanafi's maudhu'i method could include the following: first, Hassan Hanafi's thematic interpretation was juz'iyyah (specific) not kuliyah (comprehensive); secondly, Hassan Hanafi's thematic interpretation is thematic, which more analyzes on certain themes which are closely related to humanity; third, Hassan Hanafi's thematic interpretation is temporal; fourth, Hassan Hanafi's thematic interpretation is realistic; Hassan Hanafi's five thematic interpretations are oriented towards specific meanings and not just rhetoric about letters and words; sixth, thematic experimental interpretation; seventh, thematic interpretations that pay attention to contemporary problems, eighth, this shows that the interpreter's social position has changed the pattern of interpretation.
The Dynamics of Spiritual Care Among Swedish Hospital Chaplains: Approaching the Future in the Present
Authors: Grimell Jan , Bradby Hannah
Published: May 2021

This article presents a pilot study on pastors and deacons serving as hospital chaplains who provide spiritual care within a large urban hospital in Sweden. This descriptive study presents a unique contextual insight into Swedish hospital chaplains’ experiences. The purpose of this article, through the analysis of semi-structured interview material, is to describe hospital chaplains’ ability to meet medical staff and patients’ expectations. The results of the analysis are presented under three headings: chaplains in secularized spaces; chaplains filling in gaps; and cultural diversity. This will hopefully promote a conversation about the developing role of Swedish hospital chaplains in times of societal change. More research is encouraged to better detail the topic of the developing role through voices of hospital chaplains from other faith communities.
