Laminectomy alone versus laminectomy with lateral mass screw fixation in the treatment of multisegment cervical spinal canal stenosis: a comparative analysis
Authors: Elkholy Hany , El Tabl Mohamed Ahmed , El Sherif Osama Saber
Published: November 2023

Background

Multisegment cervical canal stenosis is one of the most common causes of spinal cord dysfunction. Cervical laminectomy affords direct relief from dorsal stenosis, but many concerns were raised regarding its effect on spinal stability and cervical sagittal alignment. Laminectomy in conjunction with lateral mass screws is aiming to prevent recurrence of stenosis and to achieve much improvement of the cervical spine range of motion and curvature.

Objectives

To compare the clinical and radiological outcome of laminectomy alone versus laminectomy with lateral mass screw fixation in the treatment of patients with multisegment cervical canal stenosis.

Patients and methods

A retrospective study conducted on 46 patients with multisegment cervical canal stenosis who were treated between April 2018 and April 2021. Patients were divided into two groups. The 20 cases in group (A) underwent conventional laminectomies and the 26 cases in group (B) underwent laminectomies with lateral mass screw fixation. Operative complications, visual analogue scale (VAS), neurological functional recovery and cervical curvature changes were compared between the two groups.

Results

Operative times in group A were significantly less than it was in group B (P < 0.001). The postoperative VAS scores in group B were significantly lower than those in group A (P < 0.05). No statistical differences in the modified Japanese Orthopedic Association score could be found between the two groups after surgery. Patients in group B in comparison with those in group A had good alignment of the cervical spine with maintenance of curvature index (P < 0.001).

Conclusions

In multilevel cervical canal stenosis, internal fixation using lateral mass screws in conjunction with laminectomy can be of a considerable significance than laminectomy alone in improving the axial symptoms and ceasing further disease progression through stabilization of the cervical spine and maintaining the sagittal alignment.

Introduction

Choreiform movement disorders are characterized by involuntary, rapid, irregular, and unpredictable movements of the limbs, face, neck, and trunk. These movements often initially go unnoticed by the affected individuals and may blend together with seemingly intended, random motions. Choreiform movements can occur both at rest and during voluntary movements. They typically increase in intensity with stress and physical activity and essentially cease during deep sleep stages. In particularly in advanced stages of Huntington disease (HD), choreiform hyperkinesia occurs alongside with dystonic postures of the limbs or trunk before they typically decrease in intensity.

Summary or definition of the topic

The differential diagnosis of HD can be complex. Here, the authors aim to provide guidance for the diagnostic process. This guidance was prepared for the German Neurological Society (DGN) for German-speaking countries.

Recommendations

Hereditary (inherited) and non-hereditary (non-inherited) forms of chorea can be distinguished. Therefore, the family history is crucial. However, even in conditions with autosomal-dominant transmission such as HD, unremarkable family histories do not necessarily rule out a hereditary form (e.g., in cases of early deceased or unknown parents, uncertainties in familial relationships, as well as in offspring of parents with CAG repeats in the expandable range (27–35 CAG repeats) which may display expansions into the pathogenic range).

Conclusions

The differential diagnosis of chorea can be challenging. This guidance prepared for the German Neurological Society (DGN) reflects the state of the art as of 2023.

Background

Late-life depression has been associated with volume changes of the hippocampus. However, little is known about its association with specific hippocampal subfields over time.

Aims

We investigated whether hippocampal subfield volumes were associated with prevalence, course and incidence of depressive symptoms.

Method

We extracted 12 hippocampal subfield volumes per hemisphere with FreeSurfer v6.0 using T1-weighted and fluid-attenuated inversion recovery 3T magnetic resonance images. Depressive symptoms were assessed at baseline and annually over 7 years of follow-up (9-item Patient Health Questionnaire). We used negative binominal, logistic, and Cox regression analyses, corrected for multiple comparisons, and adjusted for demographic, cardiovascular and lifestyle factors.

Results

A total of n = 4174 participants were included (mean age 60.0 years, s.d. = 8.6, 51.8% female). Larger right hippocampal fissure volume was associated with prevalent depressive symptoms (odds ratio (OR) = 1.26, 95% CI 1.08–1.48). Larger bilateral hippocampal fissure (OR = 1.37–1.40, 95% CI 1.14–1.71), larger right molecular layer (OR = 1.51, 95% CI 1.14–2.00) and smaller right cornu ammonis (CA)3 volumes (OR = 0.61, 95% CI 0.48–0.79) were associated with prevalent depressive symptoms with a chronic course. No associations of hippocampal subfield volumes with incident depressive symptoms were found. Yet, lower left hippocampal amygdala transition area (HATA) volume was associated with incident depressive symptoms with chronic course (hazard ratio = 0.70, 95% CI 0.55–0.89).

Conclusions

Differences in hippocampal fissure, molecular layer and CA volumes might co-occur or follow the onset of depressive symptoms, in particular with a chronic course. Smaller HATA was associated with an increased risk of incident (chronic) depression. Our results could capture a biological foundation for the development of chronic depressive symptoms, and stresses the need to discriminate subtypes of depression to unravel its biological underpinnings.
AP-1 signaling modulates cardiac fibroblast stress responses

Published: November 2023

Matrix remodeling outcomes largely dictate patient survival post myocardial infarction. Moreover, human-restricted noncoding regulatory elements have been shown to worsen fibrosis, but their mechanism of action remains elusive. Here, we demonstrate, using induced pluripotent stem cell-derived cardiac fibroblasts (iCFs), that inflammatory ligands abundant in the remodeling heart after infarction activate AP-1 transcription factor signaling pathways resulting in fibrotic responses. This observed signaling induces deposition of fibronectin matrix and is further capable of supporting immune cell adhesion; pathway inhibition blocks iCF matrix production and cell adhesion. Polymorphisms in the noncoding regulatory elements within the 9p21 locus (also referred to as ANRIL) redirect stress programs, and in iCFs, they transcriptionally silence the AP-1 inducible transcription factor GATA5. The presence of these polymorphisms modulate iCF matrix production and assembly and reduce cell–cell signaling. These data suggest that this signaling axis is a critical modulator of cardiac disease models and might be influenced by noncoding regulatory elements.

Purpose

Short periods of limb immobilization lower myofibrillar protein synthesis rates. Within skeletal muscle, the extracellular matrix of connective proteins is recognized as an important factor determining the capacity to transmit contractile force. Little is known regarding the impact of immobilization and subsequent recovery on muscle connective protein synthesis rates. This study examined the impact of one week of leg immobilization and two weeks of subsequent ambulant recovery on daily muscle connective protein synthesis rates.

Methods

Thirty healthy, young (24 ± 5 y) men were subjected to 7 days of one-legged knee immobilization followed by 14 days of ambulant recovery. Deuterium oxide ingestion was applied over the entire period and muscle biopsy samples were collected before immobilization, after immobilization, and after recovery to measure muscle connective protein synthesis rates and mRNA expression of key extracellular matrix proteins (collagen I, collagen III), glycoproteins (fibronectin, tenascin-C), and proteoglycans (fibromodulin, and decorin). A two-way repeated measures (time x leg) ANOVA was used to compare changes in muscle connective protein synthesis rates during immobilization and recovery.

Results

During immobilization, muscle connective protein synthesis rates were lower in the immobilized (1.07 ± 0.30 %/d) compared with the non-immobilized (1.48 ± 0.44 %/d; P < 0.01) leg. When compared to the immobilization period, connective protein synthesis rates in the immobilized leg increased during subsequent recovery (1.48 ± 0.64 %/d; P < 0.01). Following recovery, skeletal muscle collagen I, collagen III, fibronectin, fibromodulin, and decorin mRNA expression increased when compared to the post-immobilization timepoint (all P < 0.001).

Conclusions

One week of leg immobilization lowers muscle connective protein synthesis rates. Muscle connective protein synthesis rates increase during subsequent ambulant recovery, which is accompanied by increased mRNA expression of key extracellular matrix proteins.

Bala o Hustisya?: A comparative contextual analysis on the representation of extrajudicial killings in selected Filipino narrative films
Authors: Corpus Faye III , Ticlao Angelique Mira , Rojo Joanna Juvyjoy
Published: November 2023

Background: The war on drugs campaign led by President Duterte increased the prevalence of extrajudicial killing themes in Philippine cinema, reflecting societal issues and influencing the film industry. This study analyzed the representation of extrajudicial killings (EJK) through the mise-en-scene elements of aesthetics and configuration, and the common themes of the genres such as war and society, drama, action, and crime/thriller of the selected extrajudicial killings related films: Buybust (2018), Respeto (2017), and Neomanila (2017). The EJK-related films were selected due to their categorization as narrative films and exposure to the 17th New York Asian Film Festival. This study aims: (1) to identify the representation and the common themes used when representing EJK under the film genres, (2) to analyze the mise-en-scene elements of aesthetics and configuration used in the genres, (3) and to develop an understanding of how EJK-related films can represent the voiceless. Methods: This study analyzed selected films across the respective genres in determining the filmmakers’ creativity using comparative contextual analysis. Results: The results have shown that EJK in films is represented by configuration: genre conventions, aesthetics: cinematic techniques, and common themes. (1) Configuration: the genre conventions of the films similarly fall under the genre of society and war, drama, and crime and thriller which are similar in the portrayal of the catalyst, and avatars in the EJK-related films. (2) Aesthetics: cinematic techniques are only a component of a film, but not all of them can depict real events since they simply provide a filter of roles and materials used. (3) Common themes were structural inequality, competition, and war. Conclusions: The selected EJK-related films have the same commonalities of themes, film elements, and film genres. The study concludes that the three films were represented through their depiction of EJK as an ongoing societal issue in the country.

Published: November 2023

Background During the last decade, the demand for fish oil as a feed component has increased. Therefore, identifying sources of fish oil from processed catfish waste is an important task. This study aimed to analyse the relationship between fresh weight and mesenteric weight in each group of fish and determine how variations in the size of catfish (Pangasianodon hypophtalmus) and heating temperature affect fatty acid profiles. Methods The primary source of raw material used to produce fish oil is the mesenteric organ, specifically the belly fat of catfish. This material was obtained from catfish in the following categories: Group A (290-390 g), Group B (440-685 g), and Group C (890-1,100 g). The fish oil was subjected to four different levels of heating temperature (45°C, 60°C, 75°C, and 90°C). The parameters that were analysed included biometry measurements, the correlation between fish weight and mesenteric tissue, and fatty acid content. Results Significant positive linear correlations were found between body weight and mesenteric tissue in Group A (p < 0.001, r 2 = 0.65), Group B (p < 0.001, r 2 = 0.72), and Group C (p < 0.001, r 2 = 0.64). Notably, significant differences in fatty acid composition were observed among fish groups and varied heating temperatures. Within the fish group, unsaturated fatty acids ranged from 51.25% to 56.61%, n-3 fatty acids from 1.44% to 1.77%, n-6 fatty acids from 9.04% to 10.1%, and n-9 fatty acids from 35.35% to 37.43%. Temperature fluctuations led to unsaturated fatty acid contents of 52.06% to 55.55%, n-3 fatty acids of 1.28% to 1.46%, n-6 fatty acids of 8.14% to 8,45%, and n-9 fatty acids of 34.9% to 36.92%. Conclusions The best fatty acid composition in fish oil was found in Group B (with a weight between 440 g to 685 g) through a heating process at 45°C

Published: November 2023

Background It is significant to investigate students’ mathematical self-efficacy, self-concept and anxiety constructs since they have an effect on not only the process of acquiring mathematics, and academic achievement but also potential professional choices and general welfare. This study was aimed at exploring the effects of mathematical self-beliefs, namely self-concept, self-efficacy, and math anxiety on the mathematics achievement of high school adolescents. Methods The sample contains 384 randomly selected grade 12 students (M=199, F= 185) from three preparatory schools in Kafa zone. Tools were adapted from Butler (2016) and Al Mutawah (2015). The Mathematics Achievement Test (MAT) was administered to get information on mathematics achievement. Confirmatory factor analysis along with structural equation modeling was used to analyze the data. Results The results reveal that self-concept and self-efficacy have a positive and significant association with math achievement whereas anxiety has a negative relationship with math achievement but is not significant. Conclusions From the results, we conclude that self-concept and self-efficacy have significant and positive effects on mathematics achievement. We recommend that every concerned body should pay concerted effort to these motivational variables so as to encourage students’ achievements in mathematics.
A triple helix model for the diffusion of Industry 4.0 technologies in firms in the Marche Region
Authors: Testi Niccolò
Published: November 2023

Background Firms in the Marche Region, Italy, seem to struggle with understanding the importance of Industry 4.0 technologies, including blockchain technology, and delay the adoption of these innovative technologies. Methods This paper is based on findings of three levels of qualitative analysis: the first one is a literature review; the second uses secondary sources about the diffusion of Industry 4.0 in the Marche Region and the local institutions and policies favouring it, retrieved from institutional websites and web searches; the third uses primary data which has been collected through an explorative survey conducted by sending a questionnaire to local innovative firms between 25th and the 27th of October 2022. Results The literature review shows that collaboration between triple helix actors can foster innovation in firms. Secondary data about firms in the Marche Region describes an economy made prevalently of micro enterprises not capable of adopting Industry 4.0 technologies, and individuates some institutions located in the region having the role of innovation intermediaries that help firms innovate. Among the secondary sources, the new Smart Specialisation Strategy 2021-2027 of the Marche Region emphasises the role of Industry 4.0 for economic development which requires the involvement of the research and innovation actors present in the region. The survey conducted for this study shows that the firms that adopted Industry 4.0 technologies have strong ties and collaboration with triple helix institutions. Conclusions Based on the findings, a triple helix model is proposed to foster the diffusion of Industry 4.0 technologies in the Marche Region, where innovation intermediaries are called to manage knowledge flows both among them and between academia, government, and industry, to activate a virtuous cycle of innovation adoption and valorisation.

Published: November 2023

The COVID-19 pandemic has generated many fundamental and challenging implications regarding security, for both states and people. This article addresses the pandemic as a security threat, whereby societal and human dimensions of security are intertwined with the narrower (so-called traditional) state dimensions, culminating in comprehensive security. This article uses mixed methods, combining desk research and a selection of narratives or stories from several parts of the world that signify how the intersection of disinformation and populist discourses exacerbated the COVID-19 security challenges. These are analysed through an innovative comprehensive security analytical approach. Drawing on both security theory and policy, the article examines how the COVID-19 pandemic jeopardised security on multiple levels. First, the state’s capacity to effectively act and deliver in the domestic sphere waned. Second, the social contract between the state and its citizens eroded as public trust dissipated. This article argues, however, that the most pervasive threat to security during the pandemic pertained to the exploitation of the information domain in relation to the state, society, and people. The article interrogates how mis- and disinformation about the pandemic compounded and exacerbated the security challenges it posed, often relying on existing narratives within right-wing populism movements to increase mistrust and discontent. These largely right-wing populist narratives contributed to broadening the gap between states and people, besides weakening public compliance with state health security measures. The nature of populism and the narratives of particularly right-wing populism contributed to increases in fragmentation, polarisation, and discrimination impacting societal trust. The article concludes with recommendations to mitigate the adverse impacts of mis- and disinformation, including reinvigorating the relationship between state institutions and the people to strengthen comprehensive security.
A Mean-Field Control Problem of Optimal Portfolio Liquidation with Semimartingale Strategies
Authors: Fu Guanxing , Horst Ulrich , Xia Xiaonyu
Published: November 2023

We consider a mean-field control problem with càdlàg semimartingale strategies arising in portfolio liquidation models with transient market impact and self-exciting order flow. We show that the value function depends on the state process only through its law, and we show that it is of linear-quadratic form and that its coefficients satisfy a coupled system of nonstandard Riccati-type equations. The Riccati equations are obtained heuristically by passing to the continuous-time limit from a sequence of discrete-time models. A sophisticated transformation shows that the system can be brought into standard Riccati form, from which we deduce the existence of a global solution. Our analysis shows that the optimal strategy jumps only at the beginning and the end of the trading period.

Smart library utilization strategy to enhance teachers' reading interest in elementary schools
Authors: Indrayani Indrayani , Hidayati Dian
Published: November 2023

Reading is a crucial tool for unlocking the gateway to knowledge and plays a vital role in personal development. Engaging in reading allows individuals to refine comprehension skills from various angles, preventing engagement in risky behaviors due to a lack of knowledge. In educational settings, students look to their teachers for guidance and inspiration, including setting an example through reading books. Despite quality libraries and literacy programs, student interest in reading may not reach its full potential if teachers fail to act as reading role models. Unfortunately, enthusiasm for reading among teachers in Indonesia remains low. This research aims to uncover the availability of reading media in elementary schools utilizing the e-Library application (Smart Library). It focuses on the design of a reading media utilization program and the strategic implementation to enhance teachers' reading interest. Additionally, the research evaluates the impact of this media and program on teachers. A descriptive qualitative approach is employed, with research subjects from elementary schools in Bandung using Smart Library. Data collection techniques include observation, interviews, and documentation. Findings reveal the Smart Library Utilization Strategy Model to Increase Teachers' Reading Interest in Elementary Schools, comprising four steps: (1) Schools should provide comfortable reading media meeting teachers' needs, digital and physical; (2) School principals must design an innovative and diverse reading media utilization program to effectively enhance teachers' reading interest; (3) Implementation should proceed through strategic steps, from socialization to appreciation; and (4) Regular evaluation of teachers' reading interest improvement is essential to assess quality and identify factors influencing it.

Published: November 2023

BACKGROUND

Postpartum depression (PPD) is a common psychological disease among puerperal women, and postpartum pelvic floor dysfunction is a common disease among pregnant women. The occurrence of postpartum pelvic floor dysfunction will increase the incidence of PPD.

AIM

To explore the therapeutic effect of integrated traditional Chinese and Western medicine nursing combined with electrical stimulation of pelvic floor muscles and the rectus abdominis on PPD.

METHODS

From April 2020 to January 2022, 100 parturients with a rectus abdominis muscle separation distance > 2.0 cm who underwent reexamination 6 wk after delivery at our hospital were selected as the research subjects. According to the random number table method, the patients were divided into either an observation group (n = 50) or a control group (n = 50). There was no significant difference in the general data between the two groups (P > 0.05). Both groups were treated by electrical stimulation. The observation group was additionally treated by integrated traditional Chinese and Western medicine nursing. A self-designed Depression Knowledge Questionnaire was used to evaluate the awareness of knowledge on depression in all patients 3 wk after intervention. The Hamilton Depression Scale (HAMD) was used to evaluate the depression before intervention and 1 wk and 3 wk after intervention, and the Morisky Medication Adherence Scale (MMAS-8) was used to evaluate the medication compliance. SPSS19.0 was used for statistical analyses.

RESULTS

The rate of awareness of knowledge on depression in the observation group was significantly higher than that of the control group (P < 0.05). The scores of MMAS-8 were comparable between the two groups before intervention (P > 0.05), but were significantly higher in the observation group than in the control group at 1 wk and 3 wk after intervention (P < 0.05). The HAMD scores were comparable between the two groups before intervention (P > 0.05), but were significantly lower in the observation group than in the control group at 1 wk and 3 wk after intervention (P < 0.05).

CONCLUSION

Integrated traditional Chinese and Western medicine nursing combined with electrical stimulation of pelvic floor muscles and the rectus abdominis is effective in the treatment of postpartum depression and worthy of clinical promotion.
Breaking the Silence: Io and Philomela in Ovid's Metamorphoses
Authors: Celotto Giulio
Published: November 2023

ABSTRACT: This paper, which serves as the introduction to the volume, suggests that stories of ancient Roman women shattering the curtain of silence that surrounds them can be repurposed to support contemporary women's struggle to make their voice heard. In particular, the tales of Io and Philomela in Ovid's Metamorphoses can be used to amplify the powerful message of the recently developed Me Too movement, as they show that women victim of sexual assault can reaffirm their identity and reclaim their role in the community by speaking up and denouncing the violence they have suffered.

A double key (DK) real-time update and hybrid five-dimensional (5-D) hyperchaotic deoxyribonucleic acid (DNA) dynamic encryption scheme is proposed, which can ensure the security in the orthogonal frequency division multiplexing passive optical network (OFDM-PON). Chaotic sequences for DNA dynamic encryption are produced using a four-dimensional (4-D) hyperchaotic Lü system and a one-dimensional (1-D) logistic map. In this scheme, the DK consists of an external key set, which is stored locally, and an internal key, which is associated with the plaintext and external key. In addition, a pilot cluster is used as the carrier of key transmission and key embedding is achieved by converting key to phase information of the pilot. To verify the feasibility of the scheme, a simulation validation is performed on a 46.5Gb/s 16 quadrature amplitude modulation (QAM) coherent OFDM-PON system transmitted over an 80 km transmission distance. The results show that the proposed scheme can improve the security performance of OFDM-PON at a low OSNR cost of 0.3 dB and the key space is expanded to (8.514 × 10102)
S
. When the correlation redundancy (CR) G⩾7, the 0 bit error rate (BER) of key can be achieved and the key can be updated and distributed in real-time without occupying additional secure channels.
Optical analysis of aligned Ni nanowire arrays with different degree of oxidation for terahertz polarizer application

Published: November 2023

The optical properties of aligned nickel nanowire arrays (NiNWAs) with different degrees of oxidation for terahertz (THz) polarizer applications have been investigated by using THz time-domain spectroscopy. In frequency-domain spectra, the full width at half maxima of transmitted peaks was broadened and the peak positions have a blue shift with increasing oxidation levels, besides the enhancement in peak intensity. It is indicated that the oxidation of Ni nanowires (NWs) has a significant influence on the interaction between Ni NWs and THz wave. The transmittance of the aligned NiNWAs increases with annealing temperature increasing. Conversely, the degree of polarization and extinction ratio (ER) decreases. A corresponding relationship between the change of ER and degree of oxidation is summarized by means of thermogravimetric analysis. The change of ER for the annealing sample with the degree of oxidation of 0.507% is 27.32%, which induced the polarization properties of aligned NiNWAs to be sensitive to the oxidation of Ni NWs. These findings can provide new positive features in the development of future polarization-based device applications for THz electronics and photonics.
All-fiber function devices for twisted lights

Published: November 2023

Lights carrying orbital angular momentum (OAM), also called twisted lights, have been applied in fields of optical manipulation, imaging, quantum communication, and mode-division-multiplexing (MDM) optical communication systems. Traditional approaches for manipulating twisted lights carrying OAM in free space paths such as Q-plates, spiral phase plates (SPPs), and spatial light modulators (SLMs) that are usually affected by diffraction effect and imperfect alignment between different optical components, limiting the practical applications of twisted lights. Here we design, fabricated, and package all-fiber function devices for twisted light carrying OAM such as all-fiber broadband OAM generator, all-fiber OAM (de)multiplexer, all-fiber OAM & WDM coupler, and all-fiber OAM 1 × 2 coupler. Base on coupled mode theory and phase-matching condition, twisted light can be generated and detected by pre-tapered single mode fiber (SMF) fusing with multi-mode fiber (MMF). The results show that the proposed all-fiber function devices for twist light have large working broadband (at least C band), high purity (above 95%), and low insert loss (less than 3 dB). The proposed devices will open a reliable way for twisted light applied in optical fiber communications and optical interconnections.
Wavelength and polarisation dependence of pump-induced loss in Ti:sapphire
Authors: Simpson Niall , Lee Martin , Kemp Alan
Published: November 2023

We use pump beam wavelength and polarisation to demonstrate that the phenomenon of pump-induced loss in Ti:sapphire is linked to simultaneous excitation of two separate absorption bands: the Ti3+ pump band and the parasitic 400 nm residual absorption. We find that the degree of pump-induced loss is linked to the relative absorption strengths of the residual absorption band and the Ti3+ pump band at the wavelength(s) of excitation.

La noción de víctima vista desde la violencia sobre el cuerpo
Authors: Buitrago Arria Daniel , Jiménez Guzmán Camila
Published: November 2023

El propósito del presente artículo es abordar la siguiente pregunta: ¿cuál es la relación entre la noción de víctima y la violencia que se ejerce sobre su cuerpo? Para estudiar esta pregunta se parte de los estudios de Giorgio Agamben y Roberto Esposito para proponer un marco hermenéutico que permita ofrecer una nueva comprensión de la condición de víctima ejemplificada en dos contextos: los campos de concentración nazis (con base en los testimonios recopilados por Primo Levi) y el conflicto armado en Colombia (con base en los testimonios recogidos por el Centro de Memoria Histórica). Entre los resultados más interesantes que se encuentran en esta reflexión cabe destacar el rol del lenguaje en el despojo de la calidad de persona de la víctima y la ideología subyacente a todo proceso de victimización que se materializa en el cuerpo de la víctima.
Elegir en tiempos de incertidumbre
Authors: Peralta Núñez Cristian Rafael
Published: November 2023

La capacidad de elegir se ha erigido como una de las notas características de la libertad en la cultura contemporánea, pero si esta capacidad se ejerce de modo autorreferente puede meter a las personas en dinámicas que les suman en la incertidumbre. Partiendo de un estudio interdisciplinar en el que interactúan filosofía, sociología y teología, en este artículo se pretende analizar la categoría «elección» desde una de las espiritualidades más influyentes de la historia de la Iglesia Católica moderna, la espiritualidad ignaciana. El hecho de que los proyectos vitales, en los que desplegar y cargar de significado la existencia, se vean inmersos en la incertidumbre nos avoca al diálogo interdisciplinar desde el cual colaborar a la toma de decisiones del sujeto contemporáneo.

Published: November 2023

O propósito deste estudo foi realizar um levantamento da literatura publicada sobre as atividades de trabalho do profissional que atua no Serviço de Informação Aeronáutica/Aeronautical Information Service - AIS, no contexto da segurança da navegação aérea, sob a ótica da ergonomia centrada na atividade. Foi realizada uma revisão integrativa que incluiu a avaliação de artigos até julho de 2023. Para a busca dos artigos utilizou-se o Portal de Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior – CAPES em 4 quatro bases de dados: Literatura Latino-Americana e do Caribe em Ciências da Saúde - SciELO, PsycInfo (APA), Scopus e AeroSpace Data Base. Utilizou-se os seguintes descritores: aeronautical information service and/or ergonomics; aeronautical information service and/or human factors; aeronautical information service and/or decision making; aeronautical information service and/or operational safety; aeronautical information service and/or flight plan; aeronautical information service and/or air navigation. A análise dos dados dos estudos selecionados foi feita pelo método Principais Itens para Relatar Revisões Sistemáticas e Meta-análises/Preferred Reporting Items for Systematic Reviews and Meta-Analyses – PRISMA. Após ser realizada a triagem, dezesseis artigos foram incluídos nesta revisão. As publicações abordaram o uso de tecnologias de automação e segurança operacional para a navegação aérea, principalmente no que se refere ao controle de tráfego aéreo e ao planejamento de voo. Essas novas tecnologias são apresentadas como melhorias para a navegação aérea em nível mundial. Entretanto, não foram relatadas interfaces com os fatores humanos nessas publicações, particularmente o trabalho desenvolvido pelos profissionais da linha de frente. Isso demonstra uma lacuna na literatura que permita compreender as atividades reais do trabalho nos serviços de informação aeronáutica, incluindo as dificuldades em conduzi-las. Há a necessidade de serem avaliadas as atividades de trabalho numa perspectiva da ergonomia centrada na atividade, que aborde os profissionais AIS como protagonistas das situações de trabalho, no sentido de se aprimorar a segurança operacional. É importante frisar que, as estratégias de ações desses profissionais, são fundamentais para a manutenção/melhoria da segurança, regularidade e eficiência da navegação aérea.
