Authors: Zhang Lei , Zha Xiaoxiong , Ning Jiaqian , Li Wentao
Published: April 2023

Curing early age concrete (hereinafter referred to as EAC) with CO2 as a new method for capturing and storing CO2 can not only result in energy savings and emission reductions, but can also improve the performance of early age concrete and shorten the curing time, which leads to various application prospects. In this paper, we collect the existing research results at home and abroad to explain the reaction mechanisms of early age CO2-cured concrete (hereinafter referred to as EACC); summarize the effects of external factors such as carbonation time, CO2 pressure and concentration, and intrinsic factors (such as the active admixture, the water/cement ratio, and the water content) on the carbonation effect of early age CO2; detail the existing theoretical and numerical models of EACC; investigate the technology of EACC in four fields, i.e., precast concrete, cast-in-place concrete, recycled concrete, and fibre-reinforced concrete; and summarize the problems faced by existing research in application.

Published: April 2023

In this work, a coaxial dielectric barrier discharge (DBD) reactor was constructed to degrade the mixture of toluene and o-xylene, two typical benzene series. The Cu-MnO2/γ-Al2O3 series catalysts prepared by redox and impregnation methods were filled into the plasma device to degrade VOCs synergistically and explore the degradation effect. The experimental results showed that the introduction of a Cu-doped MnO2 catalyst significantly improved the pollutants’ removal efficiency and CO2 selectivity, and greatly inhibited the formation of by-products. Among them, Cu0.15Mn/γ-Al2O3 showed the highest removal efficiency (toluene was 100% and o-xylene was 100%), and the best CO2 selectivity (92.73%). The XRD, BET, XPS and SEM results confirmed that the synergistic effect between Cu and Mn in the Cu-Mn solid solution could promote the amount and reducibility of the surface active oxygen species, which improved the catalytic performance. Finally, the toluene and o-xylene decomposition pathways in the NTP catalytic system were speculated according to the detected organic matter. This work provides a theoretical and experimental basis for the application of DBD-catalyzed hybrid benzene series VOCs.

Published: April 2023

Steatohepatitic hepatocellular carcinoma (SH-HCC) is a distinctive histologic variant of HCC for the presence of steatohepatitis. This study intended to evaluate the contrast-enhanced imaging features and clinicopathological characteristics of 26 SH-HCCs in comparison with 26 age-and-sex-matched non-SH-HCCs. The frequency of obesity (34.6%, p = 0.048) and type 2 diabetes mellitus (23.1%, p = 0.042) were significantly higher in SH-HCC patients. As seen via B-mode ultrasound (BMUS), SH-HCCs were predominantly hyperechoic (65.4%, p = 0.002) lesions, while non-SH-HCCs were mainly hypo-echoic. As seen via contrast-enhanced ultrasound (CEUS), 96.2% of SH-HCCs exhibited hyperenhancement in the arterial phase. During the portal venous and late phase, 88.5% of SH-HCCs showed late and mild washout. Consequently, most SH-HCCs and all non-SH-HCCs were categorized as LR-4 or LR-5. As seen via magnetic resonance imaging (MRI), a signal drop in the T1WI opposed-phase was observed in 84.6% of SH-HCCs (p = 0.000). Notably, diffuse fat in mass was detected in 57.7% (15/26) SH-HCCs (p < 0.001). As seen via contrast-enhanced MRI (CEMRI), most of the SH-HCCs and non-SH-HCCs exhibited heterogeneous hyperenhancement in the arterial phase (80.8% versus 69.2%, p = 0.337). During the delayed phase, 76.9% SH-HCCs and 88.5% non-SH-HCCs exhibited hypo-enhancement. Histopathologically, the rate of microvascular invasion (MVI) was significantly lower in SH-HCCs than non-SH-HCCs (42.3% versus 73.1%, p = 0.025). The frequency of hepatic steatosis >5% in non-tumoral liver parenchyma of SH-HCCs was significantly higher than in non-SH-HCCs (88.5% versus 26.9%, p = 0.000). Additionally, the fibrotic stages of S0, S1 and S2 in SH-HCCs were significantly higher than in non-SH-HCCs (p = 0.044). During follow-up, although the PFS of SH-HCC patients was significantly longer than non-SH-HCC patients (p = 0.046), for the overall survival rate of SH-HCC and non-SH-HCC patients there was no significant difference (p = 0.162). In conclusion, the frequency of metabolism-related diseases in SH-HCC patients was significantly higher than in non-SH-HCC patients. The imaging features of SH-HCCs combined the fatty change and typical enhancement performance of standard HCC as seen via CEUS/CEMRI.

COVID-19 forced us to investigate risk factors to provide the best medical attention, especially in vulnerable groups, such as pregnant patients. Studies in other populations have analyzed blood groups in relation to infection, complications, and death. The present study aimed to analyze the association of blood groups with the risk of infection and complications in pregnant women and newborns from the Mexican-Mestizo population. We studied 1906 individuals. Quantitative variables were analyzed through the Student’s t-test. Categorical variables were analyzed through Pearson’s chi-square test, and logistic regression was used to analyze the association between categorical variables and outcomes. No significant association was observed between blood groups and infection risk. Individuals with the AB blood type are at higher risk for developing severe disease, although blood groups do not seem to be involved in the risk of SARS-CoV-2 infection. However, the AB blood group could be considered a risk factor for developing severe COVID-19 in the Mexican population.

Our study aimed to evaluate the association between gastric cancer (GC) and higher concentrations of the metabolites L-carnitine, γ-butyrobetaine (GBB) and gut microbiota-mediated trimethylamine N-oxide (TMAO) in the circulation. There is evidence suggesting that higher levels of TMAO and its precursors in blood can be indicative of either a higher risk of malignancy or indeed its presence; however, GC has not been studied in this regard until now. Our study included 83 controls without high-risk stomach lesions and 105 GC cases. Blood serum L-carnitine, GBB and TMAO levels were measured by ultra-high-performance liquid chromatography–mass spectrometry (UPLC/MS/MS). Although there were no significant differences between female control and GC groups, we found a significant difference in circulating levels of metabolites between the male control group and the male GC group, with median levels of L-carnitine reaching 30.22 (25.78–37.57) nmol/mL vs. 37.38 (32.73–42.61) nmol/mL (p < 0.001), GBB–0.79 (0.73–0.97) nmol/mL vs. 0.97 (0.78–1.16) nmol/mL (p < 0.05) and TMAO–2.49 (2.00–2.97) nmol/mL vs. 3.12 (2.08–5.83) nmol/mL (p < 0.05). Thus, our study demonstrated the association between higher blood levels of L-carnitine, GBB, TMAO and GC in males, but not in females. Furthermore, correlations of any two investigated metabolites were stronger in the GC groups of both genders in comparison to the control groups. Our findings reveal the potential role of L-carnitine, GBB and TMAO in GC and suggest metabolic differences between genders. In addition, the logistic regression analysis revealed that the only significant factor in terms of predicting whether the patient belonged to the control or to the GC group was the blood level of L-carnitine in males only. Hence, carnitine might be important as a biomarker or a risk factor for GC, especially in males.

Published: April 2023

With the development of distributed renewable generations, a large number of distributed generations (DGs) are connected to the microgrid. Therefore, distributed cooperative algorithms are more suitable for optimal dispatch of the microgrid than centralized algorithms. This paper proposes a novel distributed cooperative control method for optimal dispatch of microgrids, considering line losses and time delay. First, the optimization model of the microgrid considering line losses is established, and optimality conditions are obtained. Second, a novel distributed optimization method considering line losses is proposed, where the primary control is to achieve optimal dispatch, and the secondary control is to achieve frequency regulation. Third, the stability of the system under time delay is analyzed, and the robust stability conditions are obtained. Finally, simulation results verify the the effectiveness of the proposed method.
ICN-Oriented Mobility Support Method for Dynamic Allocation of Mobile Data Flows
Authors: Xing Mengchi , Deng Haojiang , Han Rui
Published: April 2023

Information-centric networking (ICN) is a promising solution that can meet the challenges of IP-based networks. ICN adopts the solution of separating name and address to solve the dual semantics problem of IP addresses, which has natural advantages in supporting mobility. These mobility support methods in ICN have realized route optimization to a certain extent. In fact, due to these methods not considering the real-time network environment, such as the bandwidth of the switching path and the characteristics of different mobile data flows, these approaches adopt the same routing optimization solution for all data flows generated by mobile users, resulting in a single switching path. The bandwidth of a single switching path may not meet the transmission requirements of mobile data flows, which will greatly affect the performance of mobile users. Therefore, how to efficiently allocate switching paths for multiple mobile data flows generated by mobile users is an urgent problem in ICN mobility support. In this paper, we first propose a mobility support method for dynamically allocating mobile data flows (DAFM) based on the ICN mobility support architecture and model the mobile data flow allocation problem as a late-binding node selection problem. We then propose a double-constraints heuristic algorithm (DCHA) based on the Moser algorithm. By simultaneously adjusting the bandwidth resource constraints of the switching path and the space resource constraints of the Mobility Flow Table (MFT), we achieve late-binding node selection to minimize average packet delay. Finally, experimental results show that our proposal can achieve mobility support. Under the guarantee of a low-latency Name Resolution System (NRS), our method outperforms other methods in terms of average packet delay, packet loss rate, and handover delay.

Published: April 2023

Researchers have, in recent times, achieved excellent compression efficiency by implementing a more complicated compression algorithm due to the rapid development of video compression. As a result, the next model of video compression, High-Efficiency Video Coding (HEVC), provides high-quality video output while requiring less bandwidth. However, implementing the intra-prediction technique in HEVC requires significant processing complexity. This research provides a completely pipelined hardware architecture solution capable of real-time compression to minimize computing complexity. All prediction unit sizes of 4×4, 8×8, 16×16, and 32×32, and all planar, angular, and DC modes are supported by the proposed solution. The synthesis results mapped to Xilinx Virtex 7 reveal that our solution can do real-time output with 210 frames per second (FPS) at 1920×1080 resolution, called Full High Definition (FHD), or 52 FPS at 3840×2160 resolution, called 4K, while operating at 232 Mhz maximum frequency.
The Study of Crystals in the Fruits of Some Apiaceae Species Using Energy-Dispersive Spectroscopy
Authors: Ostroumova Tatiana , Zakharova Ekaterina
Published: April 2023

Crystals in the fruits of Apiaceae are of great importance for taxonomy. The presence/absence and location of large prismatic crystals, druses, and spherical aggregates characterize genera, tribes, and subfamilies. When the fruits of Apiaceae split into mericarps, cell separation occurs, and probably cell death and the destruction of their walls. In clades Saniculeae and Scandicinae, this process is accompanied by the accumulation of calcium oxalate crystals in the abscission layer. However, reports of smaller crystals are rare, and their taxonomic significance is unknown. To fill this gap, we started research with four species of the clade Apieae: Ammi majus, Modesciadium involucratum, Deverra aphylla, and Rutheopsis tortuosa; in the last two species, crystals were described for the first time. We also studied crystals in Chaerophyllum bulbosum from the clade Scandicinae, and in Sanicula rubriflora from the clade Saniculeae. Conventional optical and polarizing microscopy, scanning electron microscopy, and energy dispersive spectroscopy (EDS) were used. In the clade Apieae, the studied species contained crystals in the exocarp and on the commissure, and often in the mesocarp parenchyma as well; the shapes of the crystals are small druses and crystal sand. The calcium content in the crystals was determined as 10–31%; crystals contain also carbon and oxygen and are most likely composed of calcium oxalate. In the fruits of Apiaceae studied, the silicon content is low (<0.3%).

Published: April 2023

Increased peritoneal protein loss has been associated with the fast transport of small molecules, diabetes mellitus (DM), and a reduced survival in patients on peritoneal dialysis (PD), although some studies did not confirm the association with survival. In this single-center retrospective study, we investigated the relationship of baseline peritoneal albumin and protein loss with transport status, comorbidities including DM, and survival in 106 incident PD patients during the period of July 2005–June 2014. Five-year survival rate was determined using Cox-regression analysis. There were not significant differences in D/Pcr or peritoneal protein and albumin loss between diabetics and non-diabetics. In the group of 66 non-diabetics, high and high-average transporters for creatinine had higher values for both peritoneal protein (11.85 ± 6.77 vs. 7.85 ± 4.36 g/day; p = 0.002) and albumin (5.03 ± 2.32 vs. 3.72 ± 1.54 g/day; p = 0.016) loss as compared to slow transporters. However, in the group of 40 diabetics, this association was not observed. Upon multivariable regression analysis, the independent association of D/PCr with peritoneal albumin (β = 0.313; p = 0.008) and protein (β = 0.441; p = 0.001) loss was found only in non-diabetics in whom ultrafiltration also appeared as a significant predictor of peritoneal protein loss (β = 0.330; p = 0.000). A high comorbidity grade, older age, and low serum albumin were associated with mortality, but both peritoneal protein and albumin loss as well as D/Pcr were not determinants of survival. Baseline peritoneal protein and albumin loss was not associated with DM and did not predict survival. The clinical significance of the absence of association between fast peritoneal transport status and peritoneal protein flux in diabetics should be evaluated in a prospective study comprising a greater number of diabetics with evaluation of overhydration as a main inducing variable of protein leak.

Published: April 2023

Long-lasting symptoms after SARS-CoV-2 infection have been described many times in the literature and are referred to as Long COVID. In this prospective, longitudinal, monocentric, observational study, we collected the health complaints of 474 patients (252 ambulatory and 222 hospitalized) at Lausanne University Hospital 1 year after COVID-19 diagnosis. Using a self-reported health survey, we explored cardiopulmonary, vascular, neurological, and psychological complaints. Our results show that age, Charlson comorbidity index, and smoking habits were associated with hospital admission. Regarding the vascular system, we found that having had thromboembolism before SARS-CoV-2 infection was significantly associated with a higher risk of recurrence of thromboembolism at 1 year. In the neurologic evaluation, the most frequent symptom was fatigue, which was observed in 87.5% of patients, followed by “feeling slowed down”, headache, and smell disturbance in 71.5%, 68.5%, and 60.7% of cases, respectively. Finally, our cohort subjects scored higher overall in the STAI, CESD, Maastricht, and PSQI scores (which measure anxiety, depression, fatigue, and sleep, respectively) than the healthy population. Using cluster analysis, we identified two phenotypes of patients prone to developing Long COVID. At baseline, CCS score, prior chronic disease, stroke, and atrial fibrillation were associated with Long COVID. During COVID infection, mechanical ventilation and five neurological complaints were also associated with Long COVID. In conclusion, this study confirms the wide range of symptoms developed after COVID with the involvement of all the major systems. Early identification of risk factors associated with the development of Long COVID could improve patient follow-up; nevertheless, the low specificity of these factors remains a challenge to building a systematic approach.

Published: April 2023

Drug-eluting stent (DES) recipients require 6–12 months of dual antiplatelet treatment (DAPT) and long-term aspirin mono-antiplatelet treatment (MAPT). Given the diversity of contemporary antiplatelet agents, antiplatelet treatment (APT) selection is becoming more complicated. We evaluated 15-year APT trends based on nationwide prescription data of 79,654 patients who underwent percutaneous coronary intervention (PCI) using DESs from 2002 to 2018 in Korea. DAPT (80.7%) was the most preferred initial APT post-PCI. Many DES recipients received prolonged DAPT (post-PCI 3 years: 41.0%; 10 years: 27.7%). There was a noticeable delay in DAPT-to-MAPT conversion from the mid to late 2000s (after the late-stent thrombosis concerns of first-generation DESs raised); the conversion after that was similar during the 2010s, occurring most robustly at 12–18 months post-PCI. Clopidogrel had long and increasingly been used for MAPT, surpassing aspirin. The recent increase in newer P2Y12 inhibitor prescriptions was noted. The patients treated with newer P2Y12 inhibitors were more likely younger men and presented with acute myocardial infarction. Real-world APT is evolving, and guideline–practice gaps exist. Further studies exploring the impact of diverse APT strategies on patient outcomes are expected to provide insights into optimal APT that can sophisticatedly balance the ischemic and bleeding risks.

We evaluated the correlation that Vitamin D (Vit D), cholesterol levels, and T- and Z-scores of dual-energy X-ray absorptiometry (DXA) scans have with cone beam computed tomography values assessed in the anterior and posterior regions of maxillary and mandibular jaws. In total, 187 patients were recruited for this clinical study. Patients’ ages ranged between 45 and 65 years. Patients with valid DXA results, serum Vit D and cholesterol levels, and no evidence of bone disorders in the maxilla or mandibular region were included in the study and grouped in the control (non-osteoporosis) and case (osteoporosis) groups. Patients with a history of medical or dental disease that might complicate the dental implant therapy, chronic alcohol users, and patients who took calcium or Vit D supplements were excluded. The outcome variables assessed in the investigation were Vit D, cholesterol, Z-values, and cone beam computed tomography values. Regarding the case group, a significant (p < 0.05) inverse relationship was observed between Vit D and cholesterol. Although insignificant (p > 0.05), a positive relationship was found between Vit D and the cone beam computed tomography values in all regions of the jaws, except the mandibular posterior region (p < 0.05). Pearson correlation analysis was carried out. Vit D and cholesterol showed a statistically insignificant (p > 0.05) negative association with the cone beam computed tomography values in all regions of the jaws. However, the Z-values were highly correlated with the cone beam computed tomography values in all regions of the jaws (r > 7, p < 0.05). Vit D, cholesterol levels, and Z-values in women and men from young adulthood to middle age (45–65) were related with the cone beam computed tomography values of the jaws.

We aimed to investigate the effects of maternal obesity on brain structure and metabolism in frail women, and their reversibility in response to exercise. We recruited 37 frail elderly women (20 offspring of lean/normal-weight mothers (OLM) and 17 offspring of obese/overweight mothers (OOM)) and nine non-frail controls to undergo magnetic resonance and diffusion tensor imaging (DTI), positron emission tomography with Fluorine-18-fluorodeoxyglucose (PET), and cognitive function tests (CERAD). Frail women were studied before and after a 4-month resistance training, and controls were studied once. White matter (WM) density (voxel-based morphometry) was higher in OLM than in OOM subjects. Exercise increased WM density in both OLM and OOM in the cerebellum in superior parietal regions in OLM and in cuneal and precuneal regions in OOM. OLM gained more WM density than OOM in response to intervention. No significant results were found from the Freesurfer analysis, nor from PET or DTI images. Exercise has an impact on brain morphology and cognition in elderly frail women.

Published: April 2023

(1) Background: There is growing interest in using insects to treat nutrient-rich organic wastes, such as the black soldier fly (BSF), one of the most efficient organic waste recyclers for upcycling nutrients into the food system. Although biochar (BC) was shown to enhance nutrient retention and the final product quality during the composting of livestock and poultry manure in many previous studies, little information is available on the effect of BC on livestock manure bioconversion by black soldier fly larvae (BSFL). (2) Methods: This study investigated the effect of adding a small amount of BC to chicken manure (CM) on the bioconversion system of the black soldier fly (including N2O and NH3 emissions and the final distribution of nitrogen during the treatment process). (3) Results: The lowest N2O and NH3 emission and highest residual nitrogen in the substrate were observed in the 15% BC treatment. The highest bioconversion rate of CM (8.31%) and the peak of larval biomass was obtained in the 5% BC treatment. (4) Conclusions: The results demonstrate the feasibility of adding 5% BC to reduce pollution and achieve a satisfactory BSFL-based CM bioconversion efficiency.

Anisotropic gold nanoparticles have been recognized as promising agents for medical diagnostics and cancer therapy due to their wide functionality, photothermal effect, and ability for optical signal amplification in the near-infrared range. In this work, a simple and rapid method for the preparation of bone-shaped gold nanoparticles coated with a dye-impregnated silica shell with an aminated surface is proposed. The possibility of further functionalization the nanostructures with a delivery vector using folic acid as an example is demonstrated. The average size of the resulting tags does not exceed 70 nm, meeting the criteria of cell endocytosis. The prepared tags exhibit surface-enhanced Raman scattering (SERS) spectra at excitation with lasers of 632.8 and 785 nm. Cell imaging is performed on HeLa cells based on the most pronounced SERS bands as a tracking signal. The obtained images, along with scanning electron microscopy of cell samples, revealed the tendency of tags to agglomerate during endocytosis followed by the “hot spots” effect. To evaluate the toxic and proliferative effect of the nanotags, an MTT assay was performed with two HeLa and HEP G2 cell lines. The results revealed higher viability for HEP G2 cells.
Optical Processes behind Plasmonic Applications
Authors: Babicheva Viktoriia E.
Published: April 2023

Plasmonics is a revolutionary concept in nanophotonics that combines the properties of both photonics and electronics by confining light energy to a nanometer-scale oscillating field of free electrons, known as a surface plasmon. Generation, processing, routing, and amplification of optical signals at the nanoscale hold promise for optical communications, biophotonics, sensing, chemistry, and medical applications. Surface plasmons manifest themselves as confined oscillations, allowing for optical nanoantennas, ultra-compact optical detectors, state-of-the-art sensors, data storage, and energy harvesting designs. Surface plasmons facilitate both resonant characteristics of nanostructures and guiding and controlling light at the nanoscale. Plasmonics and metamaterials enable the advancement of many photonic designs with unparalleled capabilities, including subwavelength waveguides, optical nanoresonators, super- and hyper-lenses, and light concentrators. Alternative plasmonic materials have been developed to be incorporated in the nanostructures for low losses and controlled optical characteristics along with semiconductor-process compatibility. This review describes optical processes behind a range of plasmonic applications. It pays special attention to the topics of field enhancement and collective effects in nanostructures. The advances in these research topics are expected to transform the domain of nanoscale photonics, optical metamaterials, and their various applications.
A Post-Supersessionist Reading of the Temple and Torah in Mark’s Gospel: The Parable of the Vineyard
Authors: Hillel Vered
Published: April 2023

Most interpretations of the Temple and Torah in the Gospel of Mark have held a negative view toward the Jewish institutions, declaring that the old has been replaced by the new, meaning Jesus is the new Temple and the Church has replaced the Jewish people. This article presents a post-supersessionist reading of the Temple and Torah in Mark’s Gospel, focusing on the Parable of the Vineyard (Mk 12:1–12) in the broader narrative context (11:1—13:1) and the canonical narrative, thereby maintaining the Gospel’s connection with the Jewish people and their covenant relationship with God. These two contexts frame the parable and set parameters for its interpretation, thereby preventing anti-Torah and anti-Temple interpretations and the theological belief that Christians are Abraham’s true and rightful heirs.
A Simplified Kinematics and Kinetics Formulation for Prismatic Tensegrity Robots: Simulation and Experiments
Authors: Yeshmukhametov Azamat , Koganezawa Koichi
Published: April 2023

Tensegrity robots offer several advantageous features, such as being hyper-redundant, lightweight, shock-resistant, and incorporating wire-driven structures. Despite these benefits, tensegrity structures are also recognized for their complexity, which presents a challenge when addressing the kinematics and dynamics of tensegrity robots. Therefore, this research paper proposes a new kinematic/kinetic formulation for tensegrity structures that differs from the classical matrix differential equation framework. The main contribution of this research paper is a new formulation, based on vector differential equations, which can be advantageous when it is convenient to use a smaller number of state variables. The limitation of the proposed kinematics and kinetic formulation is that it is only applicable for tensegrity robots with prismatic structures. Moreover, this research paper presents experimentally validated results of the proposed mathematical formulation for a six-bar tensegrity robot. Furthermore, this paper offers an empirical explanation of the calibration features required for successful experiments with tensegrity robots.
Discouraging the Demand That Fosters Sex Trafficking: Collaboration through Augmented Intelligence
Authors: Van der Watt Marcel
Published: April 2023

Augmented intelligence—as the fusion of human and artificial intelligence—is effectively being employed in response to a spectrum of risks and crimes that stem from the online sexual exploitation marketplace. As part of a study that was sponsored by the National Institute of Justice, the National Center on Sexual Exploitation has documented 15 tactics that have been used in more than 2650 US cities and counties to deter sex buyers from engaging with prostitution and sex trafficking systems. One of these tactics, technology-based enforcement and deterrence methods, has been used in more than 78 locations in the United States. This paper explores the issue of technology-facilitated trafficking in the online sexual exploitation marketplace and juxtaposes this with the use of augmented intelligence in collaborative responses to these crimes. Illustrative case studies are presented that describe how two organizations employ technology that utilizes the complementary strengths of humans and machines to deter sex buyers at the point of purchase. The human(e) touch of these organizations, combined with artificial intelligence, natural language processing, constructed websites, photos, and mobile technology, show significant potential for operational scaling, and provide a template for consideration by law enforcement agencies, criminal justice systems, and the larger multidisciplinary counter-trafficking community for collaborative replication in other settings.
Genèse et finalité de l'hystérie : apports de la clinique projective infantile
Authors: Boekholt Monika
Published: April 2023

Monika Boekholt, Genesis and finality of hysteria : contributions of infantile projective clinic ?

Can child psychopathology contribute to the comprehension of the adult's future psychopathological states ? This idea is inspired by the clinical and projective approach of little girls' psychical functioning during the latency period, in the way they sexualise their representations in order to replace more anxiety provoking pregenital representations. It is as if, in these cases, eroticization, as a compromise, replaced the unbearable confrontation to the maternal image, which brings on both oedipal rivalry and the risk of a depression. This could validate the thesis that hysteria is a premature flight towards the ego-sexuated body whose anti-depressive aspect fights a fundamental flaw of what is containing.

The argumentation lies on the case study of a 10 year old girl : her projective tests - Rorschach and TAT - congruently show the systematic recourse to representations of eroticized relationships as soon as depressive and/or anxiety provoking solicitations in connection to the maternal image appear. The hysterical strategy seems almost like a caricature, although its future still remains open.

Les protocoles de Rorschach de ces deux groupes d'adolescentes présentent des différences signifiantes lorsqu'on les analyse sous l'angle des difficultés d'intégration de la féminité.

Dans le premier groupe l'acceptation des positions passives ne semble pas impliquer le renoncement à la revendication phallique. Dans le second groupe, on constate l'impossibilité à renoncer à une toute puissance combinant un masculin et un féminin archaïques : l'atteinte du corps propre pouvant alors être comprise comme un mode de résolution du conflit.

Structure du fonctionnement d'un penser sans « je » : à propos du penser psychotique aux techniques projectives
Authors: Husain Odile
Published: April 2023

La structure de pensée psychotique peut être envisagée comme incarnant une version particulière du schéma général de communication « je »-« tu »-« il ». Nous passerons en revue ces trois termes de la communication pour essayer de circonscrire la façon dont, aux techniques projectives, un sujet psychotique pense le sujet supposé pensant et interprétant, pense l'examinateur supposé écoutant et pense le matériel d'examen dont il nous parle supposément.

Le déclin de la vie psychique à travers le Rorschach
Authors: Péruchon Marion
Published: April 2023

À travers les productions mentales obtenues au Rorschach et grâce à une lecture psychanalytique, l'auteur tente de cerner le destin de l'appareil psychique dans la démence sénile de type Alzheimer au regard du grand âge (centenaires). Il dégage ainsi te sort des représentations, du jugement, de l'affect, des défenses et de la relation d'objet en tenant compte de la dédifférenciation des limites intérieur-extérieur.

Le « choix de l'organe » en psychosomatique : une question périmée ?
Authors: Dejours Christophe
Published: April 2023

Christophe Dejours, La "elección del órgano" en Psicosomática : una pregunta terminada ?

En este artículo se presenta una concepción somática esbozada por el autor a partir de un debate que él persigue desde hace quince años con los principales teóricos, en el interior de la Escuela psicosomática de Paris. Según este acercamiento, el sintoma podría tener un sentido, inteligible en ciertas condiciones. A la pregunta clásica conocida bajo el nombre de "la elección del órgano", habría que substituírla por aquélla de "la elección de la función" en las descompensaciones somáticas. Esta última encontraría una respuesta en referenda a las dificultades encontradas por la "subversión libidinal" de las funciones biológicas, (próxima a la noción de sostén propuesta por Freud en la teoría de la pulsión, según la perspectiva abierta por el comentario que hace Laplanche), dificultades que estampillarían el cuerpo de puntos de fragilidad que servirían ulteriormente de blancos privilegiados al "ataque somático".

Esta concepción es a continuación sometida a la prueba de la clínica a través de la presentación de un caso, en resumidas cuentas bastante banal, de clínica ordinaria, pero que toma de pronto una consistencia inesperada respecto a aquéllo que podría haberse esperado de una descripción en términos más convencionales en relación a la teoría psicosomática generalmente admitida.

TAT et économie psychosomatique : un bilan actuel
Authors: Debray Rosine
Published: April 2023

Inclure la référence à la notion d'économie psychosomatique dans l'hypothèse diagnostique concernant l'organisation psychique du sujet implique l'utilisation d'une nouvelle fiche de dépouillement du TAT. C'est ce qui est proposé ici par l'auteur en ligne directe avec les premières fiches de dépouillement du TAT des années 68-70. Une discussion théorico-clinique accompagne ce nouveau document.

Les contenants de pensée et le Rorschach, essai de compatibilité
Authors: Lefèbvre Alex , Chromé Carole
Published: April 2023

Alex Lefèbvre y Carole Chromé, Los continentes del pensamiento y el Rorschach, ensayo de compatibilidad.

A través de esta investigación, llevada a cabo sobre 24 sujetos, los au tores se proponen ilustrar la pertinencia del modelo de los continentes del pensamiento en la comprensión de los procesos implicados en la produccion de la respuesta del Rorschach. Luego de haber calculado para cada uno de los sujetos un indicio de elaboración simbólica de las pulsiones sexuales y agresivas según el método de Cassiers, los autores se han interesado en comprender la articulación entre esta actividad de simbolización de los contenidos y las dimensiones que fundan la capacidad a pensar en la perspectiva misma de los continentes del pensamiento. Los resultados obtenidos confirman la hipótesis según la cual el nivel de simbolización de las respuestas, dépende estrechamente del grado de diferenciación y de integración de los continentes del pensamiento primordiales (cognitivos, narcisísticos y fantasmáticos).

À la recherche d'un temps à construire au Rorschach. Des facteurs formels aux liens qui les régissent
Authors: Schvartzapel de Kacero Etel
Published: April 2023

Ethel Schvartzapel de Kacero, In search of a time to construct : from formal factors to the links which connect them.

A method is never universal. Its answers to the limitations imposed by the object and to the history of knowledge. I propose in this essay a sort of dismantling in order to see the conditions of production concerning Rorschach texts. I stard by dwelling on the original text, the visual configuration of the images, to be able to perceive the transformations done by the subject when passing from a semiotic system to another. I désigne possible roads in this quest, with the help of the axes that act as vertices which narrow the sense for each subjectivité, and give place to their structural conditions.

Keywords : Rorschach image - Axes of analysis - Transformations - Temporality in Rorschach
Contribution des techniques projectives à l'étude du fonctionnement psychique des enfants dialysés et asthmatiques
Authors: Jacquemin André , Lacerda Bellodi Patricia , Sarti Renata
Published: April 2023

André Jacquemin, Patricia Lacerda Bellodi and Renata Sarti, Contribución de las técnicas proyectivas al estudio del funcionamiento psíquico de niños dialisados y asmáticos.

En este trabajo, diversas tecnicas proyectivas - dibujo, dibujo-historia, Rorschach y CAT- han sido utilizadas para comprender cómo dos grupos de niños - dialisados y asmáticos - integran su enfermedad y se organizan psíquicamente. Los niños dialisados (N=10) han sido evaluados por el dibujo-historia y el Rorschach. El grupo resiente con intensidad y sufrimiento su retraso en cuanto a su crecimiento físico. Los niños sometidos a la hemodiálisis (HD) presentan una imagen de sí mismos disminuída e inferiorizada, con serias dificultades de reacción e interacción con el otro, cuando aquellos que reciben el tratamiento CAPD (diálisis intraperitoneal continua) introducen al otro en sus relaciones pero viven sus emociones de forma más restrictiva. Los niños asmáticos (N=20) evaluados con el dibujo de la figura humana y el CAT, sufren de conflictos amenazadores y primitivos. Ellos atribuyen al mundo externo la insatisfacción de sus necesidades y tienen grandes dificultades para controlar la agresividad. Las figuras parentales son percibidas negativamente. Los resultados sugieren un disfuncionamiento de la dualidad madre-niño y una situación familiar antagonista que puede jugar un roi en la irrupción de las crisis asmáticas. Las técnicas utilizadas han permitido percibir las reacciones de los niños a su enfermedad. Los resultados obtenidos muestran la necesidad de tomar a cargo la situación en forma interdisciplinaria para que el tratamiento de la enfermedad mejore evolutivamente, tanto en los dialisados como en los asmáticos.

Clinique du clivage en méthode projective. Violence et perte à l'adolescence
Authors: Roman Pascal
Published: April 2023

Pascal Roman, Clinical work on splitting using the projective method. Violence and loss during adolescence.

The concept of splitting is treated here by way of projective clinical techniques which refer to adolescent protocols (Rorschach and TAT). The question of splitting is first discussed on a theoretical level based on a certain number of studies (S. Freud, M. Klein, C. Chabert) which make it possible to define the recourse to splitting as a modality of non-symbolic bonding (R. Roussillon). In reference to the methodological propositions whose specificity is to define the different modalities and expressive forms of splitting (splitting of the Ego, object splitting), the author proposes to indicate signs upon which it seems possible to base oneself so as to spot indications of splitting in projective protocols and also to specifiy the adjustments which are particular to splitting during adolescence, situated along the lines of depression and of perversion.

Key words : Splitting - Rorschach - TAT - Adolescence - Violence.
Inteligência artificial – aplicações e tendências

Inteligência Artificial - IA, apesar de não ter uma única definição e seu conceito ser de difícil definição, tem ganhado espaço a cada ano, se mostrando a grande aposta para as aplicações em automação e em diversas áreas da tecnologia da informação. De maneira genérica, podemos tentar delimitar um conceito para IA como sendo: uma inteligência similar à humana exibida por máquinas, com o objetivo de gerar a interface de interação entre um sistema inteligente e o mundo real. Desde a criação do conceito de IA, muito se avançou em pesquisas e aplicações, porém tem sido cada vez maior o investimento neste campo de estudo. Desta maneira, o presente artigo abordará a conceituação de Inteligência Artificial, onde poderemos ver definições sobre raciocínio, aprendizagem, reconhecimento de padrões e inferência destes mecanismos. A nova tendência da área, a IA 2.0 - aliada ao desenvolvimento rápido, novas metodologias empregadas e o que é destaque. Por fim, aplicações de IA em nosso cotidiano, bem como aplicações na área de controle e automação.
O DIÁLOGO ENTRE AS DIFERENTES CIÊNCIAS NA ORIGEM DO MAIOR PARQUE DE CONSERVAÇÃO DE RESTINGA DO BRASIL

Protected areas are spaces created to protect nature. However, these areas are contradictory because they are designed to protect the nature of the destructive human power, which provides a dichotomous vision between nature and society. Nevertheless, protected areas are not merely places where human presence is unwanted; these areas have social, economic, cultural, educational potential, among others. The protected areas view based on the idea that the human is not part of nature is seen by some authors as reflex the fragmentation of knowledges, which prevents the totality contemplation of the environmental issue. Thereby, the present work searched understand, through the creation historical process of the Parque Nacional da Restinga de Jurubatiba, the relation between the aspects related to the natural sciences and the political aspects, social and economic.

Presentación. TIC en la educación
Authors: Martínez Santiago Roberto
Published: April 2023

Si las TIC, junto con otras nuevas tecnologías, están cambiando profundamente la sociedad en que vivimos, ¿no sería más lógico preguntarse por el sistema educativo que necesita esa nueva sociedad en lugar de hacerlo por cómo utilizar esas tecnologías en el sistema actual? Si la respuesta a lo anterior es positiva, ¿qué hipótesis se pueden plantear para definir proyectos de nuevos sistemas educativos?, ¿cómo realizar la transición?, ¿qué condiciones sociales, políticas y económicas deben darse para producir un cambio de tal magnitud y trascendencia?

Por una parte, se estudia a las TIC como posibles instrumentos didácticos y se pone énfasis en las habilidades necesarias para su eficiente utilización. Sin embargo, preguntas tales como ¿cuáles son los modelos pedagógicos idóneos o convenientes para el uso de estas tecnologías?, ¿cómo se introducen las TIC no sólo en el aula sino en los currículos de la enseñanza obligatoria?, ¿qué debe enseñarse y cómo? únicamente obtienen respuestas provisionales que no se traducen en medidas concretas de forma generalizada.

Estas son algunas de las cuestiones que hemos planteado a los autores invitados a participar en este número de la Revista Iberoamericana de Educación. Por supuesto, no todas ellas quedan contestadas, pero las respuestas obtenidas muestran la posibilidad de encarar la toma de decisiones a partir de propuestas concretas y fundamentadas en la experiencia.
