Aim. To increase the accuracy of risk stratification of breast cancer Stage I–III patients based on circulating tumour cell (CTC) determination.Methods. Forty-seven breast cancer patients aged 28–77 years (median, 51 years) who were examined and treated at N.N. Blokhin National Medical Research Center of Oncology between 2015 and 2017 were enrolled in the study. The presence of CTCs was evaluated for all patients before treatment.Results. CTCs were detected in 85.1% (40 out of 47) of the patients. The CTC detection rate in patients with early and locally-advanced breast cancer was approximately the same, 88.5% (23 of 26) and 81% (17 of 21), respectively (p = 0.7). Another important prognostic factor, which tended to be reliably linked to the frequency of CTC detection, was the grade of malignancy. Grade 2 tumours were more often observed in CTC-positive patients (77.5%) than in CTC-negative patients (22.5%, p = 0.06). None of the remaining clinical and morphological parameters were statistically associated with CTC positivity.Conclusion. This study demonstrated that regardless of the clinical stage, CTCs were detected with approximately equal frequency in patients with early and locally-advanced breast cancer (88.5% and 81%, respectively). However, owing to the small number of patients studied, none of the differences were found to be statistically significant. Nevertheless, investigations on the relationship between the presence of CTCs, molecular-biological subtypes and grade of malignancy are important to evaluate their use as independent prognostic factors. Further studies are needed to assess the use of CTCs as an additional criterion or prognostic factor in breast cancer management.Received 17 September 2020.

Authors: Minin S. , Zavadovky K. , Nikitin N. , Mochula A. , Romanov A.
Published: September 2020

Myocardial perfusion imaging is considered one of the leading non-invasive diagnostic tools for the assessment of patients with known or suspected coronary artery disease and other cardiac pathologies. The technical improvement of the currently used gamma-tomographic devices has increased the diagnostic capability of this technique. In recent years, the use of dedicated cardiac SPECT cameras with solid-state cadmium–zinc–telluride (CZT) technology has increased in nuclear imaging. These new CZT technologies have several advantages over existing scanner models. The development of new CZT detectors and their collimator configuration has increased scanning sensitivity and spatial resolution values. Also, due to the significantly higher sensitivity of new CZT detectors and new methods of data processing, radiologists have already introduced new scanning protocols and methods for radionuclide assessment of myocardial blood flow, reserve and non-invasive visualisation of the functioning of the sympathetic nervous system into clinical practice. The purpose of this review is to provide data on the main technical characteristics of gamma cameras equipped CZT detectors as well as the current possibilities of using CZT cameras for examining patients with various cardiovascular diseases.Received 1 April 2020.

Published: September 2020

This publication presents the clinical observation in a paediatric patient with haemangioma of the left stomach. The effectiveness of surgical treatment of this disease is also noted. We assess the challenges in diagnosis and the choice of treatment of this pathology in children and the effectiveness of surgical treatment disease.Primary cardiac tumours are rare; vascular tumours and haemangiomas are rarer. The clinical picture of heart haemangioma is non-specific and varies as per its location and size. Echocardiography is the main diagnostic method for this disease. However, in most cases of preoperative diagnostic examination, the pre-surgery diagnosis is not confirmed. The final diagnosis of capillary haemangioma is established following immunohistochemical staining of the surgical material. Thus far, owing to the rare occurrence, a generally accepted tactic for the treatment of such patients with vascular heart tumours has not been developed.This clinical case describes our experience of treating a rare pathology in children with unusual localisation as well as the rapid successful surgical removal of the tumour without complications and with a favourable post-surgery recovery period.

Despite the development of modern diagnostic technology and intraoperative navigation, catheter ablation of ventricular tachycardia in patients with coronary heart disease remains difficult. This procedure is challenging because of the electrical heterogeneity of the damaged myocardium, which leads to the emergence of reentry cycles. The clinical case that is presented is part of a study aimed at finding a personalized approach to VT ablation.A 53 year old man with coronary heart disease, post-infarction cardiosclerosis, stenting of the right coronary artery and paroxysmal ventricular tachycardia was admitted to the cardiac surgery department with arrhythmias. Recently, this patient had experienced paroxysms of arrhythmias more frequently, up to several times a month, despite receiving antiarrhythmic therapy. Upon admission, the patient complained of a rapid heartbeat, weakness and discomfort in the chest area. The patient’s current drug therapy included betalok, cardiomagnyl and rosuvastatin. Due to his condition, the patient was asked to participate in a study with the aim of developing a personalized approach to the ablation of ventricular cardiac arrhythmias.After the patient agreed to be included in the study, he underwent a series of tests including single-photon emission computed tomography of the myocardium with perfusion and non-neutropic radiopharmaceuticals and magnetic resonance imaging of the heart with contrast. Based on these tests a targeted ablation was performed which relieved the tachycardia, the impossibility of subsequent induction and the homogenization of the substrate until the disappearance of pathological symptoms.The presented clinical case demonstrates the possibility of using non-invasive imaging methods to develop a personalized approach to VT ablation in patients with coronary artery disease. However, the diagnostic accuracy, prognostic ability and feasibility of using these methods require further study.Received 8 April 2020. Revised 22 April 2020.

Authors: Revishvili A. , Popov V. , Malyshenko E. , Plotnikov G. , Anishchenko M. , Popova N.
Published: September 2020

Aim. To evaluate the in-hospital results of the epicardial bipolar radiofrequency ablation of the pulmonary vein in the prevention of new-onset postoperative atrial fibrillation (POAF) in coronary artery disease (CAD) patients undergoing coronary artery bypass graft (CABG) surgery in a pilot randomised multi-centre controlled Pulmonary Vein Ablation (PULVAB).Methods. The pilot study was conducted for the organisation of a multi-centre randomised PULVAB trial. We enrolled 63 CAD patients without a history of AF. The inclusion criterion was CAD demanding CABG; the exclusion criteria were as follows: AF history, antiarrhythmic therapy in anamnesis, significant heart valve disease, severe renal failure and decompensating diabetes mellitus. The patients were randomised into 2 groups. Group I comprised 34 patients who underwent CABG alone, and Group II had 29 patients who underwent CABG combined with radiofrequency ablation (RFA) as the initial tool for POAF prevention. All the procedures were performed by a single surgical team using standardised anaesthetic and perfusion support.Results. There was no in-hospital mortality in either group. There were differences in the duration of the intervention, cardiopulmonary bypass time and the aorta clamping time between groups (p > 0.05). A higher incidence of POAF was observed (11 %–32.4 %) in the isolated CABG group than in the CABG combined with PULVAB group (6 %–20.7 %), although the difference was not significant (p = 0.29). In most cases (91 %), AF occurred on the second to third postoperative day, irrespective of the observation group.Conclusion. The combination of CABG and RFA does not complicate the operation and does not increase the duration of the surgery or time of cardiopulmonary bypass. There were no significant differences in the postoperative course or the incidence and structure of complications between the groups. This may indicate the safety of our method. The positive tendency of POAF-cases decrease after preventive epicardial RFA observed in the present study allows us to continue the PULVAB study to gain more statistically significant results.Clin.Trials.gov Identifier: NCT03857711

Problem uporczywej terapii w świetle filozofii człowieka
Authors: Szałata Kazimierz
Published: September 2020

The problem of medical futility, which combines the issues of euthanasia, is one of the most difficult matter of medical ethics. The theraphy becomes futile when a patient is in an agonizing state and none of the extraordinary actions can restore the life processes, which are coming to the end. The documents of Catholic Church state that actions which do not serve human life any more should be stopped so that let a man in agony die with dignity. However, under any conditions it is allowed to cause death of a man in active or passive way. Euthanasia is not only against the medical ethos but also the content of the medicine which serves the human life. The author of the article defines the conception of medical futility at the level of anthropological philosophy and notices that in practice the designation of the moment, when we deal with the medical futility, belongs to the doctors who depends on his empiric knowledge and wisdom.

Wychowanie do zrównoważonego rozwoju w kontekście katolickiej nauki społecznej
Authors: Grochowska Irena

One of the basic calls of the modern church is to call secular people to engage in the process of evangelization and building the new humanism. In 1947 Pius XII announced the apostolic constitution Provida mater Ecclesia giving in this way theological and legal form to such experience as secular institutions. In modern days the call is clearer, because it directs the invitation to all of us, to participate in building church unity recognizing only one’s vocation in the world. The biggest concern of the church is not an answer to moral responsibilities (what one should do or not), not about natural laws or sociological analyses, political or anthropological, or ethical and ideological confusion, which are the domain of the modern world, but the axis of the church is the concern, for the power coming from Christ’s cross being wasted. Catholic Social Science does not ignore philosophy, law, and science as such, but the basis of its science is Christ. The essence of realization of the Catholic Social Science program is to get acquainted with the science, upbringing in its spirit, and using it throughout activities in various social environments. Man today should realize how useful engagement and responsibility for the natural environment are. The modern church participates in the concern about the environment. In John Paul II's teachings, we could find a call to action in favor of it. Benedict XVI as one of the most important tasks of our times acknowledged the idea of balanced development.

On the spherical tokamak Globus-M2 in discharges with toroidal magnetic field B= 0.7 T by means of magnetic probes and a number of other diagnostics during neutral beam injection at the current ramp up stage, magnetic field oscillations in the range of 100-300 kHz having their frequency increasing in time, had been observed. Eigenmodes with wavenumbers $n = 1-3$ (toroidal number) and $m = 2-4$ (poloidal number) were being registered. These oscillations were identified as Alfven cascades. By means of multi-channel fluctuation reflectometer, observed eigenmodes were found to be localized near magnetic shear reversal radius. Application of MHD-spectroscopy technique allowed us to determine safety factor $q_{min}$ temporal evolution and experimental values are in well agreement with modelling results, provided by ASTRA transport code.

Effect of Slope on Infiltration Capacity and Erosion of Mount Merapi Slope Materials
Authors: Rahardjo Adam Pamudji
Published: September 2020

Infiltration which occurs on slope has a specific behavior that can be parameterized. One of the reasons is because the slope generates less ponding on the sloping soil surface. This condition affects infiltration rate and surface runoff proportion of water from any kind of rainfall distribution in time. Since surface runoff tends to be higher, erosion rate is also to be higher on slope. The slope steepness is the most important parameter of a slope. In this study, the effect of slope steepness on infiltration capacity and erosion rate of Mount Merapi bare slope material were tested in a laboratory using rainfall simulator. Three values of slope steepness of 36%, 47%, and 58% were used. The rainfall intensity was set constant and was found has rate of 116,312 mm/hour. The infiltration rate was measured by volumetric balance principle and the erosion rates were measured by collecting the eroded grains at the downstream end tank. Infiltration rate was evaluated by using Horton method and the average erosion were analyzed from the eroded grain data for each test. After fitting the recorded infiltration rate data to the Horton equation, the infiltration capacity was obtained. The results were the relationship between slope steepness and the affected the infiltration capacity and erosion for each test. Infiltration capacity is found to increase and the decrease with the increase of slope steepness while erosion rate is found to increase on the steeper slope. The increase of erosion range is between 15% to 33% for each 1o increase of slope steepness. In addition, polynomial and exponential equations were developed to express the relationship between slope steepness and infiltration capacity and also the erosion rate.

AbstractThe rapid development of space activities has increased the risk of space object collisions in orbit, particularly of space debris. This situation potentially harms satellites and endangers space missions. To date, international efforts generally result in non-legally binding products or soft laws, providing only guidance to form a national legal framework in mitigating space debris. This article aims to review Indonesia’s efficacy in regulating its space activities to minimize space debris generation and risks. It also examines mitigation efforts in several other countries with the intention of providing input for the current national legal framework. IntisariPesatnya perkembangan kegiatan antariksa meningkatkan risiko tabrakan antar objek antariksa pada orbit bumi, terutama sampah antariksa.

Published: September 2020

Background: The Home Falls and Accidents Screening Tool (HOME FAST) is used for early detection of unsafe environmental conditions at home and risk factors for falls in the elderly. However, in Indonesia there are no data on the adaptation of this instrument. Objective: To determine if the HOME FAST adaptation can be used as a screening tool for the risk of falling in the elderly in the First Level Health Facilities/Fasilitas Kesehatan Tingkat Pertama (FKTP) of Purworejo Regency. Methods: This research was a quantitative study with a cross-sectional design. Subjects were elderly with age over 65 years in the Puskesmas Loano working area that met the inclusion and exclusion criteria. Results: After the adaptation of the HOME FAST instrument was completed, a validity test was performed and a r table result of 0.361 was obtained, indicating all questions were valid. Reliability testing using the Cronbach Alpha formula obtained 0.8461. Subjects were 300 respondents with a distribution of 135 men (45%) and 165 women (55%). The results of the bivariate analysis found three factors that were statistically significantly related, namely gender, age, and the total score of the HOME FAST adaptation instrument.

Published: September 2020

Indonesia declared COVID 19 as an outbreak since March 2020, where the President of Indonesia announced the fist two cases who were cured already. Since then a lot of publication, as well as information, spread out through social media. The hoax buster of the government had already put 134 hoaxes in the website only in one month 1. Thus, one can imagine how difficult for Indonesian people to understand the situation of the outbreak and to properly respond to it. Cases increased exponentially and it was estimated that Indonesia would reach 20,000 cases at the end of March 2020 2. The fact is up till the 6th of April 2020, Indonesia reported 2,491 cases 3.What happens to the estimation? Was it wrong or a lot of underreported cases occur in the community? Is it because of the intervention that the government launched effectively?

En México la mayor parte de los bovinos productores de carne son finalizados en pastoreo. Se ha observado que el tejido adiposo de estos animales puede presentar una coloración cuasi amarilla, que provoca su rechazo por parte del consumidor y la consecuente pérdida económica para el productor. El color casi amarillo de la grasa en bovinos se debe a los carotenoides provenientes de su ingesta. En esta revisión se aborda el metabolismo de estos compuestos en los ámbitos digestivo y tisular. Aunque se conocen algunas soluciones prácticas al problema, éstas son económicamente inviables; en este contexto, es necesario estudiar más sobre las causas fisiológicas de la deposición del pigmento con el propósito de encontrar mejores soluciones

Using leaf extracts for green synthesis, essential for the reduction and oxidation process of the metals. Phyllanthus niruri (L.) and Aristolochia indica (L.) leaf extracts were used to synthesize yellowish brown coloured silver (Ag) and white coloured zinc oxide (ZnO) nanoparticles. Synthesized green nanoparticles characterized by different spectroscopic analysis (XRD, XPS, FTIR, PL) and TEM. Characterization results confirmed the particles morphology, size, structure and also their optical and photonic properties. Three different concentrations of Ag and ZnO NPs were analysed against three (gram positive) and five (gram negative) bacteria. Increased levels of green synthesized Ag and ZnO NPs showed increased zone of inhibition than amoxicillin (positive control). Our study proved that the green synthesized Ag and ZnO NPs showed similar unique physical and chemical properties with metal oxide nanoparticles but less toxic while their discharge into the ecosystem.

Authors: Al-Shawi Sarmad Ghazi , Ali Haider Ibrahim
Published: September 2020

The study was conducted to prepare control, probiotic (Lactobacillus acidophilus), and synbiotic (L. acidophilus and inulin) ice cream, L. acidophilus content, pH, titratable acidity, sensory properties were evaluated during frozen storage periods. L. acidophilus counts were the higher in synbiotic ice cream, adding inulin to probiotic ice cream enhanced significantly (P<0.05) the content of L. acidophilus. Freezing process caused a decrease in L. acidophilus counts along with storage periods in all the samples of ice cream. Synbiotic ice cream was the lower in pH values and the higher in TA values compared to the other ice cream samples. Synbiotic ice cream was the better in overall acceptance followed by probiotic and control ice cream, respectively. So, ice cream fortification with L. acidophilus probiotic bacteria and prebiotic inulin have a positive influence on all sensory characteristics. Probiotic content of both synbiotic and probiotic ice cream could be considered as functional therapeutic healthy product since it was more than the lowest concentration of probiotic bacteria to provide the beneficial attributes which are 106 cfu/g at the consumption time of the product.

Ready-to-eat food products procured from different roadside shops in Tiruchirappalli, Tamil Nadu were screened for Escherichia coli. A total of 500 samples from 250 vegetable and 250 meat products were collected from different hotels, restaurants and street food vendors in Tiruchirappalli, Tamilnadu. Out of 500 ready-to-eat food samples, 162 (32.4%) E. coli strains were isolated. The ready-to-eat meat products had higher bacterial count than the vegetable food samples collected due to unhygienic handling, improper storage, inadequate temperature to maintain processed meat and improper cooking. Biochemically identified E. coli colonies were screened for housekeeping gene uidA and 139 (85.8%) E. coli isolates were confirmed to possess β-glucuronidase activity. In addition, antibiotic susceptibility assay was performed using 12 antibiotics. From 139 E. coli strains, 96 (69.1%) isolates showed multidrug resistance. Among them, 16.7% showed 100% resistance to all the antibiotics tested. Whereas, multidrug resistant E. coli isolates showed increased resistance (75.9%) to streptomycin followed by 70-50% level of resistance to ceftriaxone, ampicillin, cefixime, ciprofloxacin, tetracycline, gentamicin, doxycycline, co-trimoxazole, norfloxacin, ofloxacin and chloramphenicol. Furthermore, drug resistant E. coli isolates 56 (58.3%) were detected with the presence of intI1. The source of contamination was found to be water and human handling. Drinking water supply from corporation might have been contaminated with fecal waste source is being discharged into Cauvery river which might disseminate horizontal gene transfer.

Published: September 2020

The main problem faced by Micro, Small and Medium Enterprises (MSMEs) actors is limited access to finance. The presence of Fintech Peer to Peer Lending companies in Indonesia is the answer to the limited access to finance faced by MSME entrepreneurs. However, the presence of Fintech Peer to Peer Lending for MSMEs in Indonesia can cause legal problems. This study aims to find a juridical basis for the relation between Fintech Peer to Peer Lending organizers and MSME entrepreneurs and to find constitutional protection for Fintech Peer to Peer Lending organizers and MSME entrepreneurs. The method used is juridical empirical, using primary data in the form of primary and secondary legal materials. The study outcomes concluded that the weak legal protection for the lenders (borrowers), which in this case is MSMEs, is due to the insufficiency of strict legitimate rules in managing the Fintech Peer to Peer Lending business. So that the implementation of the Peer to Peer Lending Fintech business needs to be regulated under the Law so that it can be charged with criminal sanctions.

Published: September 2020

Act Number 7 of 1992 as amended by Act Number 10 of 1998 concerning Banking and several related rules already regulates the exclusion of banking secrets, especially for tax purposes. However, the existing mechanism has not been able to accommodate the exchange of financial information within the framework of the Automatic Exchange of Information (AEOI). Then the Financial Information Access Act was formulated which regulates the automatic exchange of financial information that has never been known before. The problems discussed in this study, how are the exceptions of bank secrets for tax purposes that have been carried out in Indonesia and how are bank secrets exceptions regulated in the Financial Information Access Act. The research method used is a normative juridical method with a descriptive-analytical research approach. The results of the study found that the exception of bank secrets has long been known in Indonesia but is still limited by a convoluted bureaucracy. Whereas in the Financial Information Access Act, exceptions take place automatically but there are sanctions for those who misuse information.

Development of Micro, Small and Medium Enterprises (MSMEs) Through Incense Manufacturing Business Facilities (Case Study in Gondang Tegalgondo Village, Karangploso, Malang District). Internal development efforts from household entrepreneurs that produce output in the form of incense to increase potential by using initial capital with their own savings. However, because this business is still a small household business, there are several constraints, including limited human resources, lack of facilities and infrastructure to support production, and packaging of incense products as well as low knowledge about entrepreneurship, resulting in no increase in economic value due to market share the destination is still around Bali and surrounding Malang. The solutions offered to partners are counseling and socialization and discussion with partners. The result of the discussion was that partners began to understand production management efficiently by involving technologies such as incense drying tools that were still being processed, so that even though the rainy season could still produce, partners also got the knowledge that the importance of providing trade name labels related to incense was produced to add value economical on goods produced.
To the question of concrete creep in the soil environment
Authors: Ter-Martirosyan Zaven G. , Bakhmisov Viktor V.
Published: September 2020

Introduction. Concrete creep coupled with specific soil properties represent a problem for the analysis of reinforced concrete structures in geotechnical engineering. The mission of this research is to make a problem statement and to outline its potential solutions.

Materials and methods. In the course of the research, the finite element method was applied and the review of works, covering various problem aspects, was performed.

Results. Concrete creep in respect of a diaphragm wall is most vividly manifested in deflections and stresses in struts; as for piles, concrete creep is manifested by the longitudinal axial force distribution along the length. The co-authors have demonstrated that is necessary to single out the excavations device under bentonite slurry protection from the viewpoint of the construction technology. In this case, a 5–10 mm thick water-saturated filter cake is formed at the contact between soil and concrete. The filter cake retains its permanent water penetrability at some level that depends on pressure and injection time; therefore, concrete in trench cannot be considered isolated from filtration water flows. Following the concrete mix casting into the trench, water saturated filter cake is consolidated, and this enables the authors to make a conclusion about its resistance to vapour penetration.

Conclusions. If water saturation is equal to Sr > 0.5–0.6 and if excavation works are performed under the protection of the bentonite slurry, relative air humidity of soil RH can be considered to be equal to 100 %, and if water saturation Sr < 0.5–0.6, RH needs to be analysed. Identification of concrete moisture content depending on relative air humidity, the groundwater filtration flow and influence of the filter cake at the contact between ground and concrete make it possible to take account of the effect of soil conditions on concrete creep.
Efficiency assessment of urban planning transformations: economic and legal aspects
Authors: Ershova Svetlana А. , Shishelova Svetlana А. , Orlovskaya Тamara N.
Published: September 2020

Introduction. A discrepancy between legislative requirements for the compulsory recognition of economic factors in the process of drafting urban planning documents, on the one hand, and the unavailability of an approved implementation procedure, on the other hand, makes a substantial impact on decision making processes that deal with urban planning transformations. The unavailability of (a) unified approaches to the assessment of the economic efficiency of urban planning solutions, (b) an approved efficiency assessment procedure or (c) a database decelerates the process of making well-grounded urban development decisions. Therefore, development of a conceptual framework for the efficiency assessment in terms of integrated urban development actions and their implementation procedures is particularly relevant. The subject of this research consists in the study of the regulatory/methodological framework of urban development, and its mission is to analyze the main regulatory problems that accompany the efficiency assessment of urban development.

Materials and methods. The co-authors employed a socio-spatial approach that takes account of objective and subjective factors of a high-quality urban environment at various stages of the urban planning documentation drafting process. Within the framework of this approach, methods of comparative/logical analysis were applied, expert evaluations were made, materials, developed by foreign and Russian scientists, Russian legislative acts, methodological documents were studied with regard to the evaluation of the urban development efficiency.

Results. The co-authors identified gravest theoretical and methodological problems of urban transformation efficiency assessment. An assessment procedure was developed. The co-authors suggested organizing the urban transformation efficiency assessment in the course of drafting urban planning documentation. Principal efficiency assessment stages were identified, and the main objectives of each stage were formulated.

Conclusions. The novelty and practical relevance of this research reside in the fact that the co-authors have identified problems of the legal framework of assessment procedures and suggested a sequential estimation of the economic efficiency of urban transformations so that each subject of urban planning activities followed a unified research-driven decision making procedure.
Influence of operating parameters of a batch reactor on the efficiency of integrated wastewater treatment and nitrogen compound removal
Authors: Tran Ha Quan  , Gogina Elena
Published: September 2020

Introduction. The process of integrated wastewater treatment from nutrients and biogenic elements, especially from ammonia nitrogen and nitrogen compounds, is the main function in the operation of a wastewater treatment plant nowadays. Due to creating an aerobic and anoxic media in structures with suspended activated sludge, biochemical reactions of nitrification and denitrification are realized. To increase the efficiency of wastewater treatment from nitrogen compounds using suspended microflora, it is necessary to determine the influence of technological parameters – hydrogen ion concentration, dissolved oxygen level and oxidation-reduction potential (ORP) on the integrated biological wastewater treatment process.

Materials and methods. Experiments aimed at solving the problems posed for each reaction were conducted in order to determine the influence of technological parameters on the rate of nitrification and denitrification in a biological contact reactor.

Results. As a result of the experiment, the values of the specific rate of nitrification with the optimal pH value of the reactor were obtained. For the denitrification process, the ratio between the dissolved oxygen level, the ORP, and the specific denitrification rate are estimated.

Conclusions. It was shown that the pH value, dissolved oxygen level and ORP play a significant part in the process of integrated wastewater treatment from nitrogen compounds.

Authors: De Andrade Alexsandro Luiz , Fardin Pedruzzi Pâmela
Published: September 2020

Attachment refers to affective-emotional bonds developed early between child and caretaker, and to its consequences throughout life. This study aimed at constructing a measure to assess adult attachment in workplace relationships. The sample of the study consisted of 450 adult participants (62.2% female; M= 24 years old, SD= 6.69%) included in the labor market. The results of an exploratory and confirmatory factor analysis indicated a three-dimensional structure that evaluated aspects of security, anxiety and avoidance of attachment in workplace situations, explaining 55% of the total variance. In addition, dimensions in both analyses showed omega coefficients high than .80. The measure presented expected correlations with close attachment, career success, satisfaction with life and self-efficacy dimensions. In conclusion, this study offers a validated measure: The Workplace Attachment Scale (WAtS), in Brazilian Portuguese that enables the investigation of attachment relationships in the workplace.

Rompendo o isolamento: Reflexões sobre história oral e entrevistas à distância
Authors: Santhiago Ricardo , Barbosa de Magalhães Valéria
Published: September 2020

O artigo reflete sobre a possibilidade de realização de entrevistas online, conduzidas de acordo com os princípios da história oral. Busca extrapolar a enfatizada discussão técnica sobre as vantagens e desvantagens do uso de entrevistas à distância, empenhando-se em desvendar alguns dos motivos da rejeição ao seu uso e propondo um olhar aberto, e ao mesmo tempo crítico, ao uso deste recurso. Para isso, realiza quatro aproximações combinadas: discussão do lugar ocupado pelo corpo na história oral e em outros recursos de pesquisa correlatos, recuperando a centralidade do conceito de performance na literatura da área; revisão crítica da produção bibliográfica sobre o assunto, apontando suas limitações e conclusões; ponderações sobre experiências dos autores, extraindo sugestões procedimentais de pesquisas empíricas em ambiente online anteriores; e mapeamento de algumas das iniciativas de discussão e instrução técnicometodológicas surgidas a partir do isolamento social e decorrentes da pandemia da COVID-19.
