ALTERNATIVE MEDIA PRACTICES OF MIGRANT COMMUNITIES IN TURKEY: THE CASE OF AL HARMAL NEWSPAPER
Authors: RAĞBETLİ İlker , AYDIN Bayram Oğuz
Published: October 2022

Alternatif medya, ana akım medyada kendine yer bulamayan hâkim söylemin dışında kalan kesimlerin kendi seslerini kamusal alanda duyurmak için oluşturdukları medya pratiklerini ifade eder. Yine alternatif medya, yerel kültürlerin yaşatılmasına, demokratik bir kamuoyunun oluşmasına, medyada çok sesliliğin sağlanmasına; göçmenlerin, azınlıkların, marjinal grupların ya da belirli ilgi gruplarının medyada seslerini duyurmasına katkı sunabilir. Bu yönüyle ana akım medyadan farklılaşır. Özellikle göçmen toplulukların, göç ettikleri coğrafyada seslerini duyurmada, anadillerini yaşatmada ya da anavatanları ile iletişim kurmada alternatif medyanın olanaklarından faydalandıkları söylenebilir. Alternatif medya ister organizasyon yapısıyla isterse üretim biçimiyle ana akım medyadan farklı özellikler gösterir. Bu çerçevede bir medya pratiğinin alternatif medya olarak tanımlanabilmesi için onun doğasından kaynaklanan niteliklere sahip olması beklenir. Bu düşünceler ışığında çalışmamızda Şanlıurfa’da Suriyeli göçmenler tarafından çıkarılan Al Harmal Gazetesi’nin alternatif medyanın yapısal ve işlevsel özellikleri gösterip göstermediği içerik analizi yöntemi ile incelenmiştir. Elde edilen veriler incelendiğinde ise Al Harmal Gazetesi’nin yapısal ve işlevsel özellikler bakımından ana akım medyaya alternatif bir bakış açısı sunduğu anlaşılmıştır.

Social Security Rights and Social Protection Policies of Migrant Workers in the Light of International Standards
Authors: YAMAN KENNEDY Ezgi , ÇELİK Abdulhalim , KAYAGİL Muhammet Enes
Published: October 2022

ABSTRACT

Migration is a phenomenon encountered in almost every period of human history. However, today it has become a global problem. In addition to economic reasons, it is seen that the number of people who migrate due to reasons such as war and disasters is increasing. Immigrants face various risks during and after the migration process. In some countries, migrant workers are perceived as cheap labor and are generally preferred in the informal sector. This causes migrant workers, who are already vulnerable, to be socially unprotected and in an insecure environment. With Covid-19, the fact that immigrants are at a higher risk of losing their jobs and social protection inadequacies forced them to live in more difficult conditions. This study aims to emphasize the importance of social protection and social security problems of immigrants, who are more vulnerable and vulnerable in socio-economic terms, and to offer suggestions for this. For this purpose, relevant international standards and country practices were among the topics discussed.
Das Familienfideikommiss von Ostrog im Lichte des Testaments von Paweł Karol Sanguszko aus dem Jahr 1743
Authors: Graczyk Waldemar
Published: October 2022

Ordynacja zwana Ostrogską została założona przez księcia Janusza Ostrogskiego za zgodą sejmu Rzeczypospolitej w 1609 roku. W jej skład miały wchodzić dobra Ostrogskiego położone w województwach wołyńskim, kijowskim, sandomierskim i krakowskim. Ordynacja Ostrogska dostała się w ręce książąt Sanguszków za sprawą drugiej żony Pawła Karola Sanguszki (1680-1750), Marianny z Lubomirskich Sanguszkowej (zm. 1729), córki Józefa Karola Lubomirskiego i Teofili z Zasławskich, oraz siostry Aleksandra Dominika Lubomirskiego, ordynata Ostrogskiego. Po śmierci brata w 1720 roku  weszła w posiadanie ordynacji Ostrogskiej. Dobra wchodzące w skład ordynacji ostrogskiej zostały wymienione w testamencie księcia Pawła Karola Sanguszki ze wskazaniem swego syna Janusza Aleksandra jako do niego należące.
„Bizantynizm i ,,styl bizantyjski” w dyskursie komitetu troski o rosyjskie malarstwo ikonowe (1901 – 1918)
Authors: Walczak Dorota
Published: October 2022

Głównym celem niniejszego artykułu jest pokazanie odniesień do sztuki bizantyjskiej, które pojawiają się w dyskursie Komitetu Troski o Rosyjskie Malarstwo Ikonowe (ros. Комитет попечительства о русской иконописи, 1901-1918), a także wskazanie ich funkcji ideologicznych. Autor stara się pokazać, czy i w jaki sposób wzorce bizantyjskie były wykorzystywane w publikacjach tej instytucji (przede wszystkim w podlinniku ikonopisarskim Nikodima Kondakowa). Udowadnia, że zastosowanie nawiązań do sztuki bizantyjskiej było elementem postulowanego przez Mikołaja II programu odrodzenia religijnego, a także doskonale wpisywało się w teocentryczną utopię, stworzoną przez tego cara.
Management of Anaphylaxis in Pediatric Population
Authors: Kuyucu Semanur , Arıkoğlu Tuğba , Ozhan Aylin Kont
Published: October 2022

Although an increase in the incidence of childhood anaphylaxis has been reported, it remains underdiagnosed.
Foods are the most common triggers for anaphylaxis, particularly cow’s milk, hen’s egg, and nuts.
Other common causes of anaphylaxis in children and adolescents include venom and drugs. The skin is the
most commonly affected organ, but approximately 10% of patients with anaphylaxis may present without skin
symptoms, which can lead to misdiagnosis. Recognition of anaphylaxis is a great challenge in children, possibly
due to a lack of vigilance among patients, caregivers, and healthcare professionals, but also in part due to
discrepancies in the clinical definition of anaphylaxis. In addition, anaphylaxis in infants often poses a distinct
challenge because the wide spectrum of clinical manifestations and the inability of infants to describe their
symptoms may hinder prompt diagnosis and treatment. Given the rapid onset of anaphylaxis and its unpredictable
severity, rapid assessment and appropriate treatment are critical. Although the morbidity and mortality associated
with anaphylaxis are potentially preventable with the timely administration of life-saving epinephrine,
anaphylaxis is still undertreated worldwide. Long-term management of pediatric anaphylaxis is a patientcentered,
multidimensional approach that focuses on the recognition of anaphylaxis, the use of epinephrine auto-
injectors, and prevention of recurrences. Therefore, close communication and collaboration between the
child, caregivers, healthcare professionals, and schools are the cornerstone of long-term care. This paper is designed
to provide a comprehensive overview of current perspectives and concepts related to anaphylaxis in the
pediatric population in light of recent guidelines and literature.
Synthesis and Preliminary Evaluations of [18F]fluorinated Pyridine-2-
carboxamide Derivatives for Targeting PD-L1 in Cancer
Authors: Samnick Samuel , Maier Philipp , Riehl Gabriele , Israel Ina
Published: October 2022

Background:

Treatment with immune checkpoint inhibitors has improved both progression-free survival and overall survival in a subset of patients with tumors. However, the selection of patients who benefit from immune checkpoint inhibitor treatment remains challenging. Positron Emission Tomography (PET) is a non-invasive molecular imaging tool, which offers a promising alternative to the current IHC for detecting the PD-L1 expression in malignant cells in vivo, enabling patient selection and predicting the response to individual patient immunotherapy treatment.

Objective:

Herein, we report the development of novel [18F]labeled pyridine-2-carboxamide derivatives [18F]2 and [18F]3 as small-molecule probes for imaging immune checkpoint (PD-1/PD-L1) in cancer using PET.

Results:

[18F]2 and [18F]3 were prepared by an one-step radiofluorination in and 44 ± 5% and 30 ± 4% radiochemical yield and > 98% radiochemical purity for a potential clinical translation. The total synthesis time including HPLC purification was less than 45 min. [18F]2 and [18F]3 showed an excellent stability in injection solution and a significant accumulation and retention in PD-1/PD-L1 expressing MDA-MB-231 breast cancer and in HeLa cervix carcinoma cells (2- 5 cpm/1000 cells). In addition, autoradiographic analysis and inhibition experiments on tumor slices confirm the potential of both compounds as specific imaging probes for the PD-1/PD-L1 axis in tumors.

Conclusion:

The in vitro evaluation in PD-L1 expressing cells together with results from autoradiographic analysis in PD-L1 positive tumor sections suggest that [18F]2 and [18F]3 could be potential imaging probes for assessing PD-L1 expression in tumors, and warrant further biological evaluations in vivo.

Authors: Eslamzadeh Mahboubeh , Najjari Bita , Emadzadeh Maryam , Feyzi Zhaleh , Modaresi Farzaneh , Mirzaeian Sara , Behdani Fatemeh , Yazdi Aazam Sadat Heydari
Published: October 2022

Background:

Many of women and pregnant women are front-line health care workers in the COVID-19 era and are worried about the possible impacts of COVID-19 on their fetus. Due to the pressure and high working load on the healthcare workers during the COVID-19 crisis, the healthcare workers were potentially at risk of different types of mental health disorders.

Objective:

We aimed to evaluate the correlation between mental health status and the level of COVID-19 related anxiety in pregnant healthcare workers in the COVID-19 era in Iran from August 2020 to December 2020.

Methods:

This cross-sectional study included 64 pregnant clinical residents, general physicians, nurses and other medical staff who worked in the hospitals in Iran, from August 2020 to December 2020 using an anonymous online survey available on Google Form platform. The online survey consisted of socio-demographic questions, pregnancy-related questions, and questions about medical/drug history. The Persian versions of General Health Questionnaire – 28 [GHQ-28], and Corona Disease Anxiety Scale [CDAS] were also filled by the participants.

Results:

The mean age and gestational age of the participants were 31.3±3.9 years, and 24.5±10.1 weeks respectively. Psychological problems were moderate [total score GHQ-28> 40] in 9.4% [n: 6] of the pregnant healthcare workers. The frequency of moderate/severe problems in the four subclasses, including somatic symptoms, anxiety/insomnia, social dysfunction, and depression were 9[14.1%], 25[39.0%], 7[10.9%], and 10[15.6%], respectively. According to CDAS, 26.5% of participants had moderate to severe COVID-19 related anxiety. COVID-19 related anxiety and its subclasses, physical and psychological, were significantly correlated with GHQ-28 total score and its subclasses, including somatic symptoms, anxiety/insomnia, social dysfunction, and depression among pregnant health care workers [P<0.01].

Conclusion:

According to the results of the current study, over 25% of the pregnant health care workers have moderate to severe COVID-19 related anxiety; so, it is crucial for policymakers to focus on the mental health of the pregnant health care workers during the COVID-19 pandemic.
Energy Efficiency and Resource Allocation Optimization with MIMONOMA
and Backhaul Beam-forming in User-centric Ultra-dense
Networks
Authors: Mancharla Ravi , Sheikh Tasher Ali , Bulo Yaka
Published: October 2022

Background:

Non-orthogonal multiple access (NOMA) is viewed as the key multiple access
technology for 5G and beyond networks, attracting the attention of academics and industries.
NOMA and the multiple input multiple output (MIMO-NOMA) technology can improve a system’s
throughput, latency, and energy efficiency (EE) in future-generation communication networks.

Objective:

The objective of this paper is to achieve maximum EE by applying the Max-min Power
Control Algorithm (MMPCA) through sub-channel optimization, resource allocation (RA) optimization,
access point selection (APS), and user association. The EE results obtained with and without using
MMPCA are compared to the RA optimization from a conventional water-filling algorithm
(WFA).

Method:

This paper formulates a framework for user-centric (UC) joint resource allocation, such as
backhaul connection via beam-forming and Access point (AP) to user connection via MIMO-NOMA.
The user without interference is decoded using the NOMA principle. The MMPCA was also used to
optimize cooperative power allocation, sub-channel allocation, and efficient user association. The RA
for EE is framed as a mixed non-convex and non-linear function using successive convex approximation
and sum ratio decoupling converted into convex and linear. A bisection method was used to
achieve optimal RA, user association, and sub-channel assignment.

Results and Conclusion:

The simulation shows energy efficiency (EE) improvement. Similarly, it is
observed that MMPCA outperforms the WFA.

Politics and Agricultural Policy Implementation in Tanzania
Authors: Kawishe Palme Thadey , Mallya Ernest Theobald
Published: October 2022

Despite the fact that there is high agricultural policy density in Tanzania, implementation of the agricultural policies has remained ineffective. Studies to explain the causes of implementation ineffectiveness are vast. However, the political dimension of agricultural policy implementation is seldom systematically examined. Thus politics as a variable that can steer implementation has hitherto received a narrow focus. The article examines how the political dynamic has led to ineffective agricultural policy implementation in Tanzania. The article applies qualitative research methods. We used in-depth interviews with key agricultural and political stakeholders to uncover the effects of politics on agricultural policy implementation. Empirical data shows that the implementation of agricultural policies in Tanzania is vastly affected by politics. Politics has affected the allocation of resources required for effective policy implementation. The paper has also noted incidences of political capture in the form of threats, political interference, imprecise prioritisation, resource diversion, rent-seeking and embezzlement of policy implementation resources. Our analysis shows that politics matters in policy implementation. Politics has been a source of implementation disruptions when it is misapplied. This article champions the body of knowledge on the policy-politics dichotomy by arguing that applying politics rightly in the policy process can reduce implementation disruptions.

The Juxtaposition of Ritual Worlds. Maintaining Relationship in Anglican Indigenous Christian Funerals
Authors: Larson-Miller Lizette
Published: October 2022

The juxtaposition and maintenance of inherited and indigenous rituals suggests there is something in each of those sources which are felt necessary to retain as both create and express identity and faith at the heart of the ritual processes. Counter to many conversations in liturgy which advocate for full inculturation as the goal, I suggest that acculturation, rather than inculturation, may be, for certain cultures and liturgies, the preferred ritual pattern, a ritual technique to continue two identities in the midst of diversity, especially in Christian communities who live in the ongoing reality of the move from colonialism to postcolonialism. To argue this assumption first requires a conversation between incarnationally-based inculturation and the newer conversation partners of hybridity and syncretism, placing that conversation in the context of colonial and postcolonial realities before turning to an example of acculturated funeral rituals amongst the Swampy Cree of Manitoba, Canada.
Magnetic and magnetocaloric properties of Ho-=SUB=-1-x-=/SUB=-Y-=SUB=-x-=/SUB=-(Co-=SUB=-0.84-=/SUB=-Fe-=SUB=-0.16-=/SUB=-)-=SUB=-2-=/SUB=- compounds

Crystal structure, temperature and field dependences of magnetization, high-field susceptibility, and magnetocaloric effect (MCE) of Ho1-xYx(Co0.84Fe0.16)2 polycrystalline compounds (x=0-1) in magnetic fields up to 90 kOe in a temperature range of 5-400 K are investigated. An analysis of temperature dependences of magnetization (sigma) showed that, depending on the yttrium content (x), up to three "critical" temperatures can be simultaneously present in the studied samples: spin-reorientation (Tsr), magnetic compensation point (Tcomp), and Curie temperature (TC). The temperature dependence of the high-field susceptibility (chihf) of all samples with x<1 has an extremum in the vicinity of 100 K, where a significant MCE is observed, associated with a sharp change in the magnetization of the rare-earth sublattice. The temperature dependences of the magnetic entropy change (Delta Sm) and the adiabatic temperature change (Delta Tad) have a complex shape and reflect all the above-mentioned "critical" temperatures observed at different x. Keywords: magnetic properties, direct and inverse magnetocaloric effect, adiabatic temperature change, magnetic moment, Laves phases, Curie temperature, compensation point, spin-reorientation transition.

Registration of the time dependence of the number of emission sites as a tool for analyzing field cathodes current fluctuations
Authors: Kolosko A.G.  , Filippov S.V.  , Popov E.O.
Published: October 2022

A new tool for obtaining the frequency characteristics of the interaction of emission sites with adsorbates was developed. The technique is based on the use of a computerized field projector with online processing of patterns of the distribution of emission sites over the cathode surface. The resulting dependences reflect the frequency of fluctuations in the activity of individual sites. The influence of the choice of the threshold brightness parameter, the proximity of the sites to each other and the stability of the total emission current on the shape of these curves is considered. The coincidence of the shapes of curves constructed by various methods (in online mode, in post-processing mode and in the mode of random processes modeling) is analyzed. Keywords: field emission, emission current fluctuations, carbon nanotubes, registration of emission sites, adsorption processes on the surface.
Motion Artifact Reduction in Electrocardiogram Signals Through a Redundant Denoising Independent Component Analysis Method for Wearable Health Care Monitoring Systems: Algorithm Development and Validation
Authors: Castaño Usuga Fabian Andres , Gissel Christian , Hernández Alher Mauricio
Published: October 2022

Background

The quest for improved diagnosis and treatment in home health care models has led to the development of wearable medical devices for remote vital signs monitoring. An accurate signal and a high diagnostic yield are critical for the cost-effectiveness of wearable health care monitoring systems and their widespread application in resource-constrained environments. Despite technological advances, the information acquired by these devices can be contaminated by motion artifacts (MA) leading to misdiagnosis or repeated procedures with increases in associated costs. This makes it necessary to develop methods to improve the quality of the signal acquired by these devices.

Objective

We aimed to present a novel method for electrocardiogram (ECG) signal denoising to reduce MA. We aimed to analyze the method’s performance and to compare its performance to that of existing approaches.

Methods

We present the novel Redundant denoising Independent Component Analysis method for ECG signal denoising based on the redundant and simultaneous acquisition of ECG signals and movement information, multichannel processing, and performance assessment considering the information contained in the signal waveform. The method is based on data including ECG signals from the patient’s chest and back, the acquisition of triaxial movement signals from inertial measurement units, a reference signal synthesized from an autoregressive model, and the separation of interest and noise sources through multichannel independent component analysis.

Results

The proposed method significantly reduced MA, showing better performance and introducing a smaller distortion in the interest signal compared with other methods. Finally, the performance of the proposed method was compared to that of wavelet shrinkage and wavelet independent component analysis through the assessment of signal-to-noise ratio, dynamic time warping, and a proposed index based on the signal waveform evaluation with an ensemble average ECG.

Conclusions

Our novel ECG denoising method is a contribution to converting wearable devices into medical monitoring tools that can be used to support the remote diagnosis and monitoring of cardiovascular diseases. A more accurate signal substantially improves the diagnostic yield of wearable devices. A better yield improves the devices’ cost-effectiveness and contributes to their widespread application.
Prescribing Patterns of Oral Antibiotics and Isotretinoin for Acne in a Colorado Hospital System: Retrospective Cohort Study (Preprint)
Authors: Adelman Madeline J , Sivesind Torunn E , Weber Isaac , Bosma Grace , Hochheimer Camille , Karimkhani Chante , Schilling Lisa M , Barbieri John S , Dellavalle Robert P
Published: October 2022

BACKGROUND

Guidelines established by the American Academy of Dermatology recommend oral antibiotics as first-line therapy for mild, moderate, and severe acne. However, it is recommended to minimize the duration of oral antibiotic use, and there is increasing support for other systemic agents for acne.

OBJECTIVE

We sought to characterize the use of oral antibiotics and isotretinoin for the treatment of acne in the pediatric and young adult population aged 10 through 20 years and the adult population aged 21 to 45 years from 2011 to 2019.

METHODS

We conducted a retrospective, observational cohort study using electronic data from the enterprise data warehouse of the University of Colorado Anschutz Medical Campus and its affiliates, with data in the format of the Observational Health Data Sciences and Informatics (OHDSI) Observational Medical Outcomes Partnership (OMOP) common data model. Categorical values (sex, race, and ethnicity) were compared using chi-square tests, and continuous variables (age) were compared using 2-tailed t tests.

RESULTS

Our cohort of 15,704 patients was composed of mostly White (12,776/15,704, 81.4%), non-Hispanic or Latino (13,307/15,704, 84.7%), and female (11,093/15,704, 70.6%) patients. Among the 4605 male patients in the eligible cohort, 1810 (39%) received an oral antibiotic treatment, in comparison to 3109 (28%) of the 11,093 eligible women (P<.001). Among the 4605 men who were eligible for treatment with isotretinoin in this population, 988 (21.5%) received a course of isotretinoin, compared to only 10.4% (1159/11,093) eligible women (P<.001). Male patients were 1.67 times more likely to have received an antibiotic prescription (odds ratio [OR] 1.67, 95% CI 1.55-1.79) and over twice as likely to have received an isotretinoin prescription (OR 2.34, 95% CI 2.13-2.57) than female patients.

CONCLUSIONS

Minocycline was the most frequently prescribed antibiotic for the treatment of acne in this study cohort. From 2015 to 2019, there was no significant change in the number of antibiotic prescriptions over time. Men were significantly more likely to receive both oral antibiotics and isotretinoin than female patients. Multiple factors could be contributing to this discrepancy, including the burden of iPLEDGE, additional systemic treatment options for female patients, and the difference in acne severity across sexes. We could not determine the difference in severity of acne between male and female patients in our cohort, and further research is needed to ascertain the variation across sexes.

BACKGROUND

Children with medical complexity (CMC) are individuals with complex chronic conditions who have substantial health care needs, functional limitations, and significant use of health care. By nature of their health status, they have many care providers across multiple settings, making information sharing critical to their health and safety. Connecting2gether (C2), a web- and mobile-based patient-facing platform, was codeveloped with families to support and empower parental caregivers, improve information sharing, and facilitate care delivery. C2 also provided a live platform coach to conduct parental feedback and coaching sessions, which included answering questions, providing advice on usage, and addressing technological issues.

OBJECTIVE

This study was conducted to understand the experience of parental caregivers using the C2 platform and the role of the live platform coach. This study is a subset of a larger study assessing the feasibility of C2 in the care of CMC.

METHODS

Parental caregivers (n=33) participated in biweekly sessions to provide feedback and receive real-time platform use support from a trained research team member acting as a live platform coach. Parental caregivers were asked about the utility and usability of C2’s features. Questions, platform issues, and feedback were recorded on a standardized electronic data collection tool. A thematic analysis was performed to analyze parental comments, and codes were categorized into key themes. The number of comments corresponding with each code was quantified.

RESULTS

A total of 166 parental feedback and coaching sessions were conducted, with an average of 5 sessions per parental caregiver (range 1-7). There were 33 (85%) parental caregivers that participated in at least one coaching session. Technical issues and difficulties navigating C2 were addressed in real time during the sessions to encourage platform engagement. Four key themes were identified: (1) live platform coach, (2) barriers to platform usage and technical challenges, (3) platform requests and modifications, and (4) parent partnership and empowerment.

CONCLUSIONS

Parental caregivers describe C2 as a valuable tool, acting as a facilitator for enhanced care coordination and communication. Parental caregiver feedback showed that the live platform coach was a critical tool in educating on platform use and addressing technological concerns. Further study of the use of the C2 platform and its role in the care of CMC is needed to understand the possible benefits and cost-effectiveness of this technology.
Adaptation Patterns of the Berbers in Morocco and Algeria: Julian Steward's Cultural Ecological Perspectives

Published: October 2022

The relationship between the environment and humans is not one-way. How humans adapt to their environment affects the culture and environment that will be formed in the region. Berber which is one of the largest ethnic groups in the Middle East, especially North Africa, has a unique and diverse pattern of adaptation. This paper focuses on research on the adaptation pattern of the Berbers in the two regions with the largest populations, namely Algeria and Morocco. Viewed from the perspective of Julian Steward's cultural ecology, the Berber tribe which is synonymous with nomadic and herding habits is a form of environmental adaptation in the Sahara desert, while trading and farming is a form of adaptation of the Berber tribes who live and settle in the Rifs mountains in Morocco and some hilly valleys such as Kabylie , Aures, and M'azb in Algeria. The results showed that herding, nomads, exploring water holes in the desert, navigating the stars, making tents and clothes from wool and sheepskin were the result of the adaptation of the Berbers to the environment they inhabited.

Makna pada Muqaddimah Thalāliyyah dalam Al-Mu’allaqāt Karya Imru`ul-Qays
Authors: Sudarmawan Habib
Published: October 2022

Al-Mu’allaqāt merupakan syair Arab yang paling terkenal pada masa Jahiliyah. Dalam muqaddimahnya, syair ini menggunakan muqaddimah thalāliyyah, yaitu permulaan syair yang menggunakan Ghazal untuk meratapi puing-puing peninggalan sang kekasih. Puisi Al-Mu’allaqāt karya Imru`ul-Qays adalah syair yang paling banyak menggunakan Ghazal di dalamnya. Syair jahiliyah sering kali dianggap sebagai syair yang sederhana, namun layaknya puisi yang lain, syair jahiliyah juga mengungkapkan makna dengan cara tidak langsung. Tujuan penelitian ini adalah untuk mengetahui makna muqaddimah thalāliyyah dalam Al-Mu’allaqāt karya Imru`ul-Qays. Penelitian ini menggunakan teori semiotika dari Michael Riffaterre, sekaligus menggunakan metode yang digagas oleh Riffaterre yaitu pembacaan heuristik, pembacaan hermeneutik, mencari matriks, model, dan varian, serta hipogramnya. Sumber data berupa muqaddimah thalāliyyah yang ada di dalam syair Al-Mu’allaqāt karya Imru`ul-Qays. Hasil penelitian ini adalah bahwa muqaddimah thalāliyyah dalam syair ini mengadung makna kerinduan si aku terhadap kekasihnya, sehingga membuat si aku menderita sakit pada psikisnya. Kerinduan itu diungkapkan dengan menyebut-nyebut reruntuhan tempat tinggal sang kekasih yang tak lagi dihuni olehnya.

This study aimed to reveal the functions of the jumlah ismiyyah which consist anna al-maṣdariyyah in the novel Abwābu al-Madīnati by Ilyās Khūrī by utilizing syntactic theory related to functions. The data in this study were in the form of jumlah ismiyyah consisting of anna al-maṣdariyyah. Technique of collecting data in this study used the referral method with tapping technique as a basic technique and note-taking technique as an advanced technique. This study used the agih method as the analysis stage with the Direct Element Technique (BUL) as a basic technique with i‘rāb model and substitution technique as an advanced technique. Furthermore, the presentation of the results of data analysis was done by using informal methods.

Based on the research that has been done, it can be concluded that in the Abwābu al-Madīnati novel by Ilyās Khūrī, there were 101 jumlah ismiyyah consisting of anna al-maṣdariyyah. Those 101 jumlah ismiyyah were classified based on their functions, such as khabar mubtada`, fā‘il, maf‘ūl bih, mustaṡnā, ma‘ṭūf, and ism majrūr. Jumlah ismiyyah consisting of anna al-maṣdariyyah with the form maṣdar mu`awwal can be replaced with ism in the form of maṣdar ṣarīḥ. The substitution of maṣdar mu`awwal with the form maṣdar ṣarīḥ did not cause a change in meaning and grammatical function because both of them get the same position in a sentence. Then the use of maṣdar mu`awwal in that novel gives a specific time marker for an action in a sentence and makes the meaning of the sentence become more cultured.

Authors: D’Angelo Verónica Sofía , Albino Airasca Daniel
Published: October 2022

Introducción: En una universidad privada se propusieron algunas estrategias para disminuir los niveles de deserción en el ciclo introductorio, mediante innovaciones en asignaturas con elevado número de contenidos que evidencian un bajo rendimiento académico. Se propuso incluir el uso de aplicaciones 3D para el aprendizaje de anatomía humana en una Licenciatura de Kinesiología y Fisiatría, con una estrategia pedagógica colaborativa basada en recomendaciones internacionales para aplicaciones de anatomía 3D educativas –tales como el uso de planos canónicos y referencias de orientación espacial– y en sugerencias para el aprendizaje colaborativo.

Objetivo: Explorar la percepción de un grupo de estudiantes de kinesiología en relación a dos aplicaciones 3D para el aprendizaje de anatomía humana mediante una estrategia pedagógica colaborativa y metacognitiva.

Método: Estudio exploratorio. Cuestionario TAM de aceptación de tecnología a través de Google Forms a 60 estudiantes de ciclo básico de Kinesiología y Fisiatría. Las variables principales son la facilidad de uso y la utilidad percibidas.

Resultados: Los resultados de la encuesta indicaron una alta aceptación general de ambas aplicaciones. La utilidad percibida es favorable en un 82% y muy favorable en un 18%. La facilidad de uso percibida es favorable en un 72% y desfavorable en un 28%. Se mostró cierta preferencia por Visible Body en la encuesta de opinión (83.33% vs 16.67%).

Conclusiones: La percepción general es positiva para la manipulación de la aplicación con la estrategia mencionada. Dada la alta probabilidad de uso futuro, es viable realizar nuevos estudios para investigar la relación entre el aprendizaje de conceptos anatómicos y el uso de aplicaciones 3D.

Published: October 2022

Introducción: Se puede definir al cuidado progresivo (CP) del paciente como la organización del cuidado en función de sus necesidades médicas y de enfermería, desde el ingreso al establecimiento hasta el seguimiento externo. Se diseñó un programa de residencia en CP basado en actividades profesionales a confiar (APC).

Objetivo: Describir el proceso de identificación, desarrollo y validación de APC para el programa de Residencia en CP.

Método: Se realizó una revisión teórica sobre la especialidad en CP para definir el perfil del especialista en CP. Se redactaron las APC para el programa. Su validación se implementó mediante metodología Delphi en dos rondas donde participaron 24 profesionales. Cada APC fue consultada por su representatividad y su indispensabilidad, conservando aquellas que alcanzasen el 70% de acuerdo. También se evaluó la exhaustividad de cada espacio de aprendizaje. En la segunda ronda se sometieron aquellas APC que no alcanzaron el 70% de representatividad incorporando modificaciones de redacción sugeridas.

Resultados: Un especialista en CP entiende al hospital como un conjunto de instrumentos y herramientas que integran y abordan al paciente y que utiliza para gestionar su cuidado desde el ingreso y continúa incluso fuera del establecimiento.

Se definieron 52 APC organizadas en 9 espacios de aprendizaje que permitieron alcanzar el perfil profesional establecido.

De las 52 APC evaluadas, 47 alcanzaron el 70% de representatividad e indispensabilidad. Las 5 APC restantes fueron sometidas a una segunda ronda Delphi luego de introducir modificaciones en su redacción, logrando representatividad en 3 de ellas.

Conclusiones: La formación de profesionales de la salud se dirige hacia una adquisición de competencias, que les permitan transitar logros en distintos tiempos según necesidad.
