Neste trabalho discutem-se alguns tópicos fundantes do pensamento interdisciplinar além de apresentar duas teorias elementares, a saber: a teoria geral de sistemas e a teoria cibernética de segunda ordem. Tal recorte teórico teve o propósito de explanar de forma resumida sobre os principais tópicos fundantes da interdisciplinaridade para aclarar a importância tanto do pensamento quanto da atitude holística da humanidade. Posteriormente foi realizada a discussão relativa às mídias sociais disponibilizadas atualmente. Os pesquisadores explanaram acerca do potencial de colaboração, interação, socialização e compartilhamento de dados, informações e conhecimentos via aparatos tecnológicos. Objetivando apresentar as similitudes das duas áreas, esta pesquisa bibliográfica assumiu um caráter teórico, de abordagem qualitativa e exploratória, que apontou no sentido do entendimento das mídias atuais como aplicações práticas do pensamento sistêmico e interdisciplinar. Tópicos como a interação, a retroação, a homeostasia e a equifinalidade foram observados dentro do recorte apresentado, o que leva à conclusão da pertença das mídias sociais dentro do espectro interdisciplinar. Os princípios trazidos por Bertalanffy e Foerster estão presentes na dinâmica da Web 2.0 e podem ser claramente observados nas mídias sociais. Tais recursos são vislumbrados, ainda, como mediadores de ecossistemas específicos e potenciais arenas para criação, organização e compartilhamento de informações e conhecimentos; a colaboração e a interação, são peças fundamentais no que tange à vivência de uma comunidade para criar um contexto favorável à partilha e criação de novas informações e conhecimentos.

Published: October 2022

Neste ano de 2022, em que se comemoram os 200 anos da Independência do país, este artigo aborda um aspecto das comemorações do Centenário da Independência ocorrido no ano de 1922: o lançamento da Pedra Fundamental de Planaltina, ocorrido em 7 de setembro, hoje um monumento tombado no âmbito do Distrito Federal. Em termos metodológicos, privilegiamos a análise do patrimônio como prática institucional de organização da informação a partir do processo de tombamento da Pedra Fundamental de Planaltina instaurado em 1981 e concluído em 1982 pela Secretaria de Educação e Cultura do Distrito Federal. A partir da análise dos documentos que instruem o processo, identificamos mecanismos de construção discursiva sobre o bem em questão e igualmente sobre o próprio processo de transferência da capital para Brasília. Neste sentido, os documentos que compuseram o processo de tombamento foram analisados numa perspectiva de construção social/institucional desses registros. Ao observar a instrução do processo de tombamento, por meio dos mecanismos de organização da informação, analisamos as peças documentais que compuseram o processo e a relação estabelecida entre elas. Como resultado principal dessa análise, pudemos observar como a constituição desse dossiê de tombamento instituiu o próprio bem tombado, no caso, a Pedra Fundamental de Planaltina, ao tempo que elabora uma narrativa para a transferência da capital federal para o interior de Goiás.

This study aimed to understand the incidence of Strongyloides spp. infecting wild rodents in Malang City during October to December 2021 by stratified random sampling. A total of 50 rats (Rattus norvegicus, Rattus rattus diardii, Mus musculus), 26 male (52%) and 24 female (48%). Following 12 juveniles (24%) and 38 adults (76%). Coprology examinations use floatation and sedimentation methods immediately after the gastrointestinal tract's stool collection (GITs). We also administered a limited survey to get responses from 80 people (housewives, sellers, employee, and students) to obtain risk transmission, public awareness, and attitudes. We were continually analyzed data using the chi-squared and Fisher Exact Test. The microscopic examination of stools was 28% positively detected S. ratti. Our study found an association presented between the age of rats and Strongyloidiasis infections (p<0.05). However, the gender of rats did not have a significant association (p>0.05) to the S. ratti several infections. In addition, most participants did not understand the zoonotic disease and these infections, indicating a low-level knowledge 71 (88%), because better education supports the increase of awareness. However, almost all participants have good practice of hygiene and sanitation toward COVID-19 situations 72 (90%). The further study recommends investigating Strongyloidiasis infections in another species and increasing the education program for housewives and sellers in a traditional marketplace to have better knowledge.

Published: October 2022

The objective of this paper is to estimate the trend of Total Ozone Column (TOC) over Togo. Multi Sensor Reanalysis-2 (MSR-2) TOC over the entire territory of Togo were used. Multiple Linear Regression (MLR) method has been applied to retrieve the interannual contributions of different forcings and the long term variability. It was found that the Annual Oscillation (AnO), the Quasi Biennial Oscillation at 30 mb (QBO30), the Solar Flux (SF), and the El Niño–Southern Oscillation (ENSO) have statistically significant influence on the interannual variability of the TOC. The strongest contribution (22 ± 1.4 DU) is allocated to the AnO while the weakest (< 1 DU) is attributed to the Semi-Annual Oscillations (SAnO). Before the peak year of Equivalent Effective Stratospheric Chlorine (EESC) in tropics in 1997 the trend is negative (- 0.3% ± 0.9% per decade) and is not statistically significant. After the peak year, a statistically significant positive trend is observed. The trend of TOC is 0.6% ± 0.2% per decade. The monthly TOC trend over Togo is positive and statistically significant during the rainy season (particularly during the monsoon period) except in April, unlike during the harmatan period (DJF) where the trend is not significant.

Correction of the Contribution of Scattered Photon Radiation to the Ionization Chamber ReadingsDuring X-Ray Radiation Quality Assessment
Authors: Zaharadniuk A. A. , Senkovsky K. G. , Lukashevich R. V.
Published: October 2022

Reduction of the systematic error when determining the characteristics of the reference X-ray radiation fields is an essential task according to the ISO 4037-1:2019 standard. This task is especially important in dosimetry laboratories when establishing the qualities of reference photon fields. The aim of the study was to develop a method that allows taking into account the contribution of radiation scattered on the filter when determining the half-value layer of the photon field generated by the X-ray unit. Another goal was to reduce the computational cost of determining this contribution.

One of the major contributors to the systematic error in measuring the half-value layer is the radiation scattered on the filter material. The standard recommends that this error should be taken into account in the measurement. But it does not provide any methodology that would do this.

The study investigated the possibility of reducing the contribution of scattered radiation to the ionization chamber readings when assessing the radiation quality of the X-ray unit by the means of half-value layer. The study utilized the (N, H, L) quality series as reference fields according to ISO 4037-1:2019.

Contribution of the scattered radiation to the half-value layer was compensated with the correction coefficients; they were calculated with the FLUKA Monte Carlo software according to the zero-aperture approximation method. Unlike other similar methods, the proposed approach employs kinetic energy released to matter (kerma), to air in this case, as the main value, which, when utilized instead of deposited energy, reduces the program’s runtime several fold.

Correctness of the results obtained in this work was verified by comparing the calculated values of the half-value layer with the tabulated ones provided in the ISO 4037-1:2019 standard. The deviation of calculated values from those specified in the standard does not exceed 2 %.

Calculation results showed that the error contributed by scattered radiation to the magnitude of the halfvalue layer in direct measurements does not exceed 5 %. The use of the air kerma allowed us to significantly reduce the time for calculating the correction coefficients by the factor of 6–16 times with respect to other methods, depending on the radiation quality series. This made it possible to calculate correction factors for the source-detector distance equal to 2.5 meters.
Calculation of Correction Factors for Vickers’ Hardness Measurements on a Non-Planar Surface
Authors: Sandomirski S. G. , Val’ko A. L. , Rudenko S. P.
Published: October 2022

The exact determination of Vickers HV hardness is important for determining of the product material mechanical properties. An important aspect of measuring HV is to obtain its values on a non-planar surface. Regulatory documents contain table values of correction factors K which depend on the surface shape (convex or concave, spherical or cylindrical), its curvature (diameter D) and hardness (arithmetic mean d of indentation diagonal lengths) but this does not solved the problem. The K values for d/D ratios not given in the tables are determined by interpolation from the closest to the measured tabulated d/D values. The error in the representation of these tabulated d/D values is fully included in the error of determining the K coefficient for the measured d/D ratio. The aim of the work was to simplify the calculation of correction factors K for Vickers hardness measurements on non-planar surfaces and to reduce the calculation error compared to the methodology governed by the regulations.

The method presented is based on a statistical analysis of K coefficients, presented in regulatory documents for cases considered in the form of tables. The sufficiency of using of a quadratic power function for approximating K(d/D) dependences and the necessity of fulfilling the physically justified condition K ≡ 1 at zero curvature of tested surface have been substantiated. Simplification of calculation of K coefficient and decrease of calculation error in comparison with the recommended in the regulatory documents obtaining of K value by linear interpolation relative to two adjacent table values are shown.

The reduction of the calculation error in comparison with the calculation recommended in the regulatory documents occurred because of the reason that when calculating by the developed formulas, the error in the value of the calculated for a specific value of d/D coefficient K is averaged over all n values of d/D given in the table of GOST for a given surface. That is, the error is reduced by a factor of about √n 2 in comparison with the calculation according to the regulated procedure. This is illustrated by the above numerical data and an example of the use of the method.

The obtained formulas for calculation of correction coefficients K when measuring hardness HV on spherical and cylindrical (concave and convex) surfaces are reasonable to use for automatic calculation of HV on items with a non-planar surface.
Multiple Stenting without Coils for Traumatic Pseudoaneurysm of Supraclinoid Internal Carotid Artery: Two Case Reports
Authors: Seo Dong-Min , Cho Yongjae , Kim Young goo , Yang Na Rae
Published: October 2022

Traumatic intracranial pseudoaneurysm (TIPA) is a very rare disease that is difficult to diagnose and treat and has high mortality and morbidity. Various treatment methods, such as microsurgery and endovascular treatment, have been proposed because TIPA accompanies traumatic brain injury. It is necessary to consider the location and characteristics of the TIPA and the patient's condition. According to previous reports regarding the endovascular treatment of TIPA, most cases were treated with stent-assisted coil embolization. Unlike previous studies, however, we would like to share our experience of two cases successfully treated by overlapping three closed-cell self-expandable stents without coils.
Advances in the Understanding of H2S Paths into the ESP Electrical System
Authors: Pessoa Rodrigues Rui Francisco , Alsaif Abdolrahman Abdullah
Published: October 2022

One of the challenges electric submersible pumps (ESPs) face in harsh environments is the corrosion of copper electric components caused by H2S. Copper is aggressively and quickly corroded by H2S, compromising the electrical integrity of the system. ESP improvements, such as the metal-to-metal motor lead extension (MLE), has had a positive impact in the ESP's run life in sour environments, and it sparked the creativity for further similar enhancements throughout the ESP system. Understanding the path of the H2S into the motor is of paramount importance to effectively aim the resources for these additional enhancements.

This paper offers an outlook of the components that play a key role in allowing the H2S to enter the electrical system. It is supported by evidence from the dismantle, inspection and failure analysis (DIFA) of motors, MLEs, and seal sections with and without H2S scavenger, and having different times of exposure based on their run life. For the objective of this paper, all observations are to revolve around the electrical integrity of the ESP.

When examining the copper end rings of motor rotors, it has been observed that the H2S attack is concentrated at the top of the motor. Similarly, from tandem seals with bags in series and H2S scavengers, where the scavenger (copper tube) in the top chamber was corroded more severely than in the bottom chamber. Furthermore, in ESP systems where the H2S had been successfully scavenged at the top of the motor or the seals no further corrosion was observed in the lower parts of those components. These observations indicate that the source of the contamination is at the top of the seal section, with no concerning H2S entrance happening below (i.e., flanges and threaded parts relying on o-rings). For all practical purposes, these conclusions are of great benefit in determining the components that require enhanced H2S protection. They also suggest that developing and implementing metal-to-metal connections all along the ESP components is either not necessary or of least priority.

The findings of this paper are intended to help direct the efforts of future ESP improvements in terms of H2S resistance toward key components. The analysis of the novel information presented here confirms that the main entry point for H2S in the ESP electric system is the top of the seal section. The shaft mechanical seals are a particular suspect. If so, vibration could be a major contributor, but further study is required to understand the effect of vibration on the rate of contamination through the shaft mechanical seals.
Enhancing the Performance of the PMM for ESP and PCP Applications with the VSD Technology of Submersible Motor Control and Direct Torque Control Respectively
Authors: Mohamed Motaz , Ramasamy Thangavel Athishkirthik , Huttunen Ari , Eskola Matti , Niemela Matias , Chernikov Vitaly
Published: October 2022

One of the challenges with the ESP Permanent Magnet Motor (PMM) has always been starting the PMM due to the difficulties in producing torque at zero frequency and operating it efficiently throughout the entire load range. Another challenge in the PCP PMM is the rapid response to the PCP torque changes and performance efficiency. This paper describes the latest VSD functionalities that have been developed to eliminate the above challenges and enhance the PMM performance in both Artificial Lift applications.

Traditionally, IR compensation based on voltage boost has been used to start the ESP PMM, however it can cause overcurrent and step-up transformer saturation. To overcome these issues, the Submersible Motor Control (SMC) mode of the VSD features user-configurable start functions based on current control to increase the robustness of starting the ESP PMM. In addition, the SMC mode features an energy optimizer function designed for the ESP PMM to increase energy efficiency throughout the entire operating range. The VSD uses Direct Torque Control (DTC) for PCP PMM applications to enable superior control performance and energy efficiency.

The SMC's current control-based start functions, such as the ‘Kick-start’ and the ‘Acceleration assistance’ were successfully tested in numerous real ESP wells with PMM and step-up transformer. These functions apply configurable current boosts at low speeds to the PMM for a set period to build sufficient starting torque and to enable robust acceleration of high loads towards the production speed range in a controlled manner. The tests showed that these start functions were able to robustly start and accelerate the ESP PMM to the production speed reference without the motor being pulled out of synchronous rotation. Once the start functions are finished, the SMC motor control switches to the Energy optimizer mode, which automatically minimizes the motor current by a Maximum-Torque-Per-Ampere (MTPA) principle throughout the operation range. Tests showed that with the Energy optimizer the PMM power factor was improved, and the energy efficiency was clearly increased. Especially with partial loads the energy savings can be remarkable compared to traditional V/F curve-based control methods. The high control performance and efficiency of DTC for PCP PMM was demonstrated in several real PCP wells, i.e. sensor-less observer-based backspin control and dynamic torque and speed responses even at low speeds.
An Effective Solution to Extend the ESP Run Life in Sour Fields
Authors: Al Khalifah Jawad Mansour , Aleissa Mohammad Ahmed , AlMutairi Khaled Mouawad , Alquwizani Saud Abdulaziz
Published: October 2022

Throughout the past decades, the Electrical Submersible Pumps (ESPs) have been deployed across different oil fields in an Arena of Artificial Fields. It was a proven fact that the typical run life of an ESP can exceed multiple years. However, that fact could be reversed especially in designated fields with high Hydrogen Sulfide (H2S) partial pressure; where specialized ESP design is required. The presence of the Hydrogen Sulfide (H2S) can result in various and vast forms of corrosion products attacking the ESP components which eventually resulted in an ESP shorter run life compared to average. Hydrogen Sulfide (H2S) can also react with formation water (H2O) and form Sulfuric Acid (H2SO4) or free Sulfur; which is another source of corrosion product affecting the installed ESP system.

As part of continuous improvement in equipment's reliability, several Dismantle inspection and failure analysis (DIFA) were done for ESP premature failures to identify the root causes along with the recommendations and forward plan to enhance ESP run life. The results of these DIFAs indicated a common root cause of ESP failures are related to Hydrogen Sulfide (H2S) presence and well fluids entering the ESP internal components. In particular, the packer penetrator, Motor-Lead-Extension (MLE), and the pothead interface were found to be the main reasons. Consequently, an effort was rolled out to control the Hydrogen Sulfide (H2S) presences at these three locations in order to maintain the ESP reliability and prolong its run life. This presented paper will demonstrate the methodologies and fit-to-purpose ESP design that contributed in extending the ESP run life in a high Hydrogen Sulfide (H2S) pressure fields. Also, a captivated practice along with related technologies have been adapted for the sour environment which resulted in sustaining the ESP run life.
Compact, Pressure-Actuated Downhole Safety Valve Improves Safety and Efficiency for Cable Deployed ESPs
Authors: Crawford Rob , Manning Matt , Hamilton Fraser , Harcourt Charles
Published: October 2022

An advanced downhole sub-surface safety valve (SSSV) has been developed to create an improved well control solution for slim-line, cable deployed Electric Submersible Pump (ESP) applications. The new SSSV enables all safety regulations to be met whilst simplifying deployment and retrieval.

During traditional ESP deployments the production tubing is replaced, allowing power cables and control lines to run outside the tubing. However, slim-line cable deployed ESPs are retrofitted through existing tubing, which means the ESP cable and SSSV control lines can cause an obstruction to the existing SSSV. To maintain a functioning SSSV a modified valve can be retrofitted into an existing safety valve profile nipple and is designed to seal around the ESP cable. However, this option is limited to wells with existing wireline retrievable SSSV profile nipples and associated control lines that are in acceptable condition.

The new advanced SSSV does not require a control line and functions based on the ESP intake to discharge differential pressure signal. The valve is installed at the ESP depth and opens when the ESP is pumping, with a fail-safe closing mechanism when the ESP is switched off. The deployment configuration can be varied to suit the application, either as an ingrated part of the cable deployed ESP assembly, or separately. As sealing around the ESP cable is not required, the new technology significantly reduces cost and complexity of cable deployed ESP installations where a SSSV is required. The new technology can also be used in other artificial lift systems.

Background: Acute graft-versus-host disease (aGVHD) is a life-threatening complication after allogeneic hematopoietic stem cell transplantation. First-line treatment of aGVHD is corticosteroid. Second-line therapy mainly comprises immunosuppressants. However, ∼ 25% of the patients have a steroid-resistant and therapy-refractory disease, which is associated with a very poor prognosis. An alternative therapy option for steroid-refractory and therapy-refractory aGVHD is the use of mesenchymal stromal cells (MSCs). Here, we report the results of 88 patients with grade III-IV aGVHD treated with human umbilical cord derived mesenchymal stromal cells (UC-MSC).
Methods: There were 18 children and 70 adults with grade III/ IV aGVHD (82% grade IV). These patients were either resistant to steroids or refractory to 1–5 additional immunosuppressants. UC-MSCs were transfused at a median dose of 1 × 106 cells/kg with a median of 4 times (range, 1 to 16).
Results: Median time between the onset of aGVHD and the first infusion of UC-MSC was 7 days (range, 3–88). The day 28 overall response rate was 51.14%, of these, 24 patients (27.27%) showed complete remission (CR), 21 (23.86%) showed partial remission (PR). The estimated survival probability at 100 days was 43.3%. And after a median follow-up of 66 months (26–122 months), the survival rate was approximately 33% (29/88). Patients developed acute gastrointestinal (GI) tract and liver GVHD showed worse overall response in day 28 than patients only with acute GI GVHD (21% vs. 58%; p= 0.037). No patient had severe side effects.
Conclusions: These results suggest that UC-MSC treatment was safe and effective in children and adults, and should be considered for treating steroid-refractory aGVHD.

Numerical groundwater flow simulation involves manual and tedious pre-processing and post-processing procedures. Hence, this study developed a systematic and efficient workflow to alleviate model buildup and data-processing burdens, allowing researchers to focus on the application aspects of simulation results. This highly automatic workflow allows researchers to execute three-dimensional groundwater flow simulations in sites with complex hydrogeological conditions. Processes in the workflow are formed as a trilogy: building a hydrogeological conceptual model, generating a site-specific unstructured mesh and specifying simulation conditions, and executing the simulation and post-processing results. The workflow feasibility has been demonstrated by simulating the three-component (water, brine, and air) fluid flow in Huayu Islet, the only andesitic island of the basaltic Penghu archipelago, using TOUGH3 (Transport Of Unsaturated Groundwater and Heat version 3) and its EOS7 (Equation Of State #7) fluid module. Our self-developed mesh generator can produce a locally refined unstructured mesh with millions of grid cells that can capture the essential geological features of Huayu. It was found that, of the three scenarios considered, only the one using a fine mesh coupled with a two-phase Dirichlet boundary condition at the top surface could obtain a physically meaningful bowl-shaped fresh water and brine interface and reasonable transport pathway characteristics. In summary, the developed workflow serves as a practical methodology to authentically characterize the hydrogeologic mechanisms of a site with complicated geology.

Authors: Lu Yixin , Zhang Yan , Tian Yutong
Published: October 2022

Background
Smart hospital at home(HaH) have become a potential solution to the medical service needs of patients at home, but little is known about their application effects in the disabled elderly. It is necessary to map HaH management models and describe their forms, content, strategies, and evaluation indicators.
Methods
A scoping review was conducted based on the framework from Arksey and O’Malley. PubMed，Web of Science，Wangfang，CNKI，VIP and OpenGrey were searched until June 30,2022. Mapping existing the smart HaH management for the disabled elderly, including form, content, strategy, and evaluation.
Results
There were a total of 8 included studies，which focused on the following issues: The forms of management covering: mobile medical and telemedicine;The content covering clinical consultation, establishment of patient health records, guidance on equipment use, and alarm management; Strategy covering the formation of multidisciplinary teams, clarification of team members' responsibilities, comprehensive assessment before bed admission, and dynamic grade assessment throughout the process; Evaluation covering patient health outcomes, smart medical dependence, patient satisfaction evaluation, management program compliance and feasibility;
Conclusions
Smart HaH management presents comprehensive, holistic, targeted, and dynamic, and is relatively consistent in terms of management form, content, and strategy characteristics, and has achieved positive application effects. However, there is still a lack of high-quality research data and standardized and unified management evaluation criteria, and there is an urgent need to conduct a multi-center, large-sample study of smart HaH management programs for the disabled elderly.

Published: October 2022

Background
The specific binding ratio (SBR) of 123I-FP-CIT in the putamen is widely used to support the interpretation of dopamine transporter (DAT) SPECT. Automatic methods for computation of the putamen SBR often include stereotactical normalization of the individual DAT-SPECT image to an anatomical standard space. This study compared using a single 123I-FP-CIT template image as target for stereotactical normalization versus multiple templates representative of normal and different levels of Parkinson-typical reduction of striatal 123I-FP-CIT uptake.
Methods
1702 clinical 123I-FP-CIT SPECT images were stereotactically normalized (affine) to the anatomical space of the Montreal Neurological Institute (MNI) with SPM12 either using a single custom-made 123I-FP-CIT template representative of normal striatal uptake or using eight different templates representative of normal and different levels of Parkinson-typical reduction of striatal FP-CIT uptake with and without attenuation and scatter correction. In the latter case, SPM finds the linear combination of the multiple templates that best matches the patient’s image. The putamen SBR was obtained using hottest voxels analysis in large unilateral regions-of-interest predefined in MNI space. The histogram of the putamen SBR in the whole sample was fitted by the sum of two Gaussians. The power to differentiate between reduced and normal SBR was estimated by the effect size of the distance between the two Gaussians computed as the differences between their mean values scaled to their pooled standard deviation.
Results
The effect size of the distance between the two Gaussians was 3.83 with the single template versus 3.96 with multiple templates for stereotactical normalization.
Conclusions
Multiple templates representative of normal and different levels of Parkinson-typical reduction for stereotactical normalization of DAT-SPECT might provide improved separation between normal and reduced putamen SBR that could result in slightly improved power for the detection of nigrostriatal degeneration.

Background: Interparental violence has persistent adverse effects on victimized parents and children. Young children, including infants and toddlers, are at particular risk to develop long-lasting negative outcomes, and yet specific evidence on effective intervention approaches for this vulnerable group is still lacking. This study will test the effectiveness of an attachment- and trauma-informed intervention approach in a sample of parent-child dyads who have experienced severe interparental violence. We test the individual and combined effects of two interventions: 1) ‘Nederlandse Interventie Kortdurend op Atypisch oudergedrag’ (NIKA; Dutch, Short-term Intervention focused on Atypical parenting behavior) aimed at improving the attachment relationship, and 2) eye movement desensitization and reprocessing (EMDR) therapy aimed at reducing parental post-traumatic stress disorder (PTSD) symptoms.
Methods: This study uses a multicenter randomized controlled design across multiple domestic violence shelters in the Netherlands. We aim to recruit 150 parent-child dyads with children aged between 0.5-6 years old. The study design consists of two phases. During the first phase for testing the effect of NIKA only, eligible dyads are randomly allocated to either NIKA or a waitlist usual care group. A pre-test is conducted prior to the treatment period and a post-test takes place directly afterwards (six weeks after the pre-test). Phase 2 follows directly for testing the effects of EMDR and the combination of NIKA and EMDR. Parents who report clinical PTSD symptoms are randomly allocated to either EMDR therapy or a waitlist usual care group. Parents who do not report clinical PTSD symptoms only receive care as usual. Six weeks later, a post-test of phase 2 is conducted for all participating dyads. Primary study outcomes are disrupted parenting behavior, sensitive parenting behavior, and parental PTSD symptoms. Secondary study outcomes include PTSD symptoms and behavioral and emotional problems of the child.
Discussion: This study will inform and enhance the clinical field by providing new insights regarding effective treatment combinations for traumatized parents and their young children after interparental violence.
