ТASHTYK SWORD
Authors:   Novosibirsk State University, O. Mitko
Published: August 2022

In 1962, an iron sword entered the funds of the Khakass Museum of Local Lore. It was discovered under random circumstances in the vicinity of the Podsinee village (currently a suburb of the city of Abakan). Yu.S. Khudyakov attributed the sword to the Tashtyk culture and gave a brief description of its size. According to the classifi cation, the sword is in Group I — rhombic, type 1 — with an emphasis for the plate crosshair. An analysis of weapons rare for the Tashtyk culture made it possible to supplement its description and make a number of clarifications. The sword is forged from a strip of iron, including a triangular crosshair. Forge welding was not used, traces of processing with abrasives are not fixed. The blade is straight, at the crosshairs it tapers, the cross section of the blade is rhombic, turning into a lenticular. The handle is rectangular, the end is broken, but presumably it ended with a small hook.With a total length of 53 cm, it is close to the size of «small» swords, and in terms of blade length it meets the standards of akinak. The weight of the sword is 830 grams, the main weight falls on the hilt and crosshairs. This is a weapon of a foot warrior; due to its small size it is not effective for combat use by a mounted warrior. Testing has shown that for thrusting, the index finger is placed over the crosshair, which allows for better control of the blade. In our opinion, the sword is of imported origin.

Ocorrência de besouros polinizadores em inflorescências de dendezeiro tratado com injeção de inseticidas
Authors: Moura José Inácio Lacerda , Pereira Rosane Rodrigues da Costa , Caliman Mateus Endringer , Pereira Carlos Eduardo
Published: August 2022

Os mais importantes polinizadores do dendezeiro são Elaeidobius subvittatus e Elaeidobius kamerunicus (Coleoptera: Curculionidae). Assim, deve-se buscar metodologias para o manejo integrado de pragas que preservem esses organismos benéficos. Por isso, nessa pesquisa objetivou-se verificar em dendezeiro o efeito de injeções de abamectina ou de imidacloprido sobre a incidência de besouros polinizadores. O estudo foi desenvolvido na Estação Experimental Lemos Maia, Ceplac em Una, no estado da Bahia utilizando-se dendezeiros com 12 anos. Aplicou-se imidacloprido ou abamectina via injeção e verificou-se a emergência de adultos em inflorescências masculinas. Foi utilizado o delineamento experimental inteiramente casualizados. O número de indivíduos da espécie E. kamerunicus, independentemente do tratamento aplicado, foi superior ao de E. subvittatus. Além disso, o número E. kamerunicus e de E. subvttatus que emergiram de plantas que receberam injeções de abamectina ou de imidacloprido não diferiram significativamente da testemunha, sem tratamento inseticida. Assim, conclui-se que a aplicação de abamectina ou de imidacloprido via injeção em dendezeiros não afeta o número de indivíduos de E. kamerunicus e E. subvttatus que emergem das flores masculinas.

Published: August 2022

The use of plant extracts to induce resistance against pathogens has shown to be a promising alternative in the management of plant diseases. The objective was to evaluate the potential of ethanolic extract of Mormodica charantia on management of the Curvularia eragrostidis and enzyme activation involved on defense responses in yam (Dioscorea alata). The isolate of C. eragrostidis was obtained from leaves of yam with symptoms. Mycelial growth and sporulation were evaluated. The treatments were: extract of Momordica charantia 10, 100, 500 and 1000 ppm, acibenzolar-S-methyl (200 mg.L-1), fungicide (200 g.ha-1) and control. The evaluations were done daily, until the 15th day of the application of the treatments. The severity of the disease was evaluated at the end of the experiment, by the size of lesions in each plant. For determination of β-1,3-glucanase and phenylalanine ammonia lyase, leaves were collected in periods of 192 h after treatments application. Fungitoxic action of the treatments in the control of C. eragrostidis in vitro was verified. The M. charantia extract conferred significative levels of protection in yam plants against C. eragrostidis reducing incidence and disease severity. Thus, it was promoted increase in enzymatic activity, preconditioning yam in induced defense mechanisms.

Authors: Ren Bo , Zhu Zhicheng , Yang Fan , Wu Tao , Yuan Hui
Published: August 2022

High-altitude satellites are visible to more ground station antennas for longer periods of time, its requests often specify an antenna set and optional service windows, consequently leaving huge scheduling search space. The exploitation of reinforcement learning techniques provides a novel approach to the problem of high-altitude orbit satellite range scheduling. Upper sliding bound of request pass was calculated, combining customized scheduling strategy with overall antenna effectiveness, a frame of satellite range scheduling for urgent request using reinforcement learning was proposed. Simulations based on practical circumstances demonstrate the validity of the proposed method.

Authors: Donnini Marco , Esposito Giuseppe , Pisano Luca , Petrucci Olga , Lollino Piernicola , Reichenbach Paola
Published: August 2022

Indicators and indexes are quantifiable parameters used in scientific disciplines to summarize and communicate complex data in a simple and explanatory manner. In the field of natural hazards, indicators and indexes have been used to characterize natural processes, and the associated risk conditions in terms of impact, vulnerability, exposure, and resilience. In this paper, we formalize indicators at the municipal level to differentiate the Italian territory based on the spatial distribution of landslides. The indicators were combined with other information to define indexes able to better characterize the stability conditions of the municipalities and quantify the possible impact of slope movements on the road network. Indexes were defined only for the Umbria Region (Central Italy), which was chosen as an example. The proposed indicators and indexes show, in a simple way, the severity of the instability on the territory and can be used to support decision-makers to assess, evaluate, and manage landslide mitigation activities and civil protection actions.

Liminal People(s) in the Late Bronze Age Levant? A New Light on Sherden (šerdanu)
Authors: Mynářová Jana
Published: August 2022

This article focuses on issues related to political liminality in the environment of the Levant in the Late Bronze Age. It first defines the term and then identifies key population groups that can be considered politically liminal. The main focus is on the so-called Sherden (Akk. šerdanu, širdanu), a group of persons and individuals, which are found in ancient Near Eastern and Egyptian sources spanning several centuries during the second half of the second half of the second millennium BCE. Whether as incoming enemies or as individuals settled on Egyptian soil, they represent one of the key phenomena of the Egyptian New Kingdom. But who were the Sherden and how did their role in the ancient Near Eastern and Egyptian societies change over time?
Exaggerated mini-puberty in a preterm girl: a case report and review of literature
Authors: Lattuada Martina , Molinari Silvia , Nicolosi Maria Laura , Doni Daniela , Lui Cristina , Passoni Paolo , Polizzi Serena , Ocello Laura , Evasi Veronica , Calia Margherita , Gustuti Violante , Cattoni Alessandro
Published: August 2022

Objectives

Mini-puberty is the physiological and transient activation of the hypothalamic–pituitary–gonadal axis occurring during the first months after birth. In preterm infants, the hormonal surge is more pronounced and longer-lasting than in at-term-peers. To date, only few cases of vaginal bleeding in the setting of an exaggerated mini-puberty have been reported.

Case presentation

At the corrected age of 3 months, an ex-very-preterm girl presented with breast enlargement and recurrent vaginal bleeding. A remarkable increase in gonadotropins and estradiol levels was detected, while pelvic ultrasound highlighted a large right ovarian cyst. As brain and pituitary MRI showed negative findings, an exaggerated mini-puberty was suspected and no additional investigations were undertaken. The subsequent progressive regression of clinical, biochemical and sonographic findings confirmed the diagnosis.

Conclusions

Although exaggerated mini-puberty of infancy in ex-preterm girls is a rare event, it is important to raise knowledge of this para-physiological condition in order to avoid unnecessary investigations and treatment.
Cervical ripening as an outpatient procedure in the pandemic – minimizing the inpatient days and lowering the socioeconomic costs
Authors: Kummer Julia , Koenigbauer Josefine Theresia , Callister Yvonne , Pech Luisa , Rath Werner , Wegener Silke , Hellmeyer Lars
Published: August 2022

Objectives

With an increasing incidence of labor induction the socioeconomic costs are increasing and the burden on hospital capacities is rising. In addition, the worldwide SARS-CoV-2 pandemic asks for improvements in patient care during pregnancy and delivery while decreasing the patient-staff contact. Here, we are retrospectively analyzing and comparing a mechanical ripening device that is utilized as an outpatient procedure to misoprostol and dinoprostone as inpatient induction methods in a low risk cohort.

Methods

This is a retrospective comparative analysis of obstetric data on patients who presented for cervical ripening and labor induction. Ninety-six patients received a mechanical ripening agent as an outpatient procedure. As a control group, we used 99 patients with oral misoprostol (PGE1) and 42 patients with vaginal dinoprostone (PGE2) for cervical ripening in an inpatient setting. Data from 2016 until 2020 were analysed.

Results

Baseline characteristics showed no significant differences. Delivery modes were similar in all groups. The time period from patient admission to onset of labor was significantly shorter in the outpatient group (p<0.001): 10.9 h/0.5 days (±13.6/0.6) for osmotic dilator vs. 17.9 h/0.7 days (±13.1/0.5) for oral misoprostol vs. 21.8 h/0.8 days (±15.9/0.7) for vaginal dinoprostone. With 20.4 h/0.8 days (±14.3/0.6) the osmotic dilator group displayed significantly the shortest inpatient stay from admission to delivery (p=0.027). The patient subgroup of misoprostol had 25.7 h/1.1 days (±14.9/0.6) of inpatient stay from admission to delivery and the patient group of dinoprostone 27.5 h/1.1 days (±16.0/0.7). There were fewer hospital days in the outpatient group: 84.9 h/3.5 days vs. 88.9 h/3.7 days vs. 93.6 h/3.9 days (outpatient osmotic dilator vs. inpatient misoprostol and dinoprostone, respectively).

Conclusions

New approaches are required to decrease individual contacts between patients and staff while maintaining a high quality patient care in obstetrics. This analysis reveals that outpatient mechanical cervical ripening can be as safe and effective as inpatient cervical ripening with PGE1/PGE2, while lowering patient-staff contact and total hospital stays and therefore decreasing the socioeconomic costs.
The Alpha Power Rayleigh-G family of distributions
Authors: Agu Friday Ikechukwu , Eghwerido Joseph Thomas , Nziku Cosmas Kaitani
Published: August 2022

This paper introduces a two-parameters generator of continuous statistical probability distributions called the Alpha Power Rayleigh-G (APRAY-G) family, some statistical properties of the family of distributions were derived, and we introduced a two-submodels of the generator. We estimate the parameters of the models based on the method of maximum likelihood estimation and explored simulation studies based on the introduced submodels. We observed that the biasedness and root mean square errors decrease as the sample size becomes large. We examined the applications of the models based on real-life data sets. We compared the obtained results with some existing probability distribution models. The results showed that the proposed models gave a better fitness to the data under investigation.
Augmenting the Realized-GARCH: the role of signed-jumps, attenuation-biases and long-memory effects
Authors: Papantonis Ioannis , Rompolis Leonidas S. , Tzavalis Elias , Agapitos Orestis
Published: August 2022

This paper extends the Realized-GARCH framework, by allowing the conditional variance equation to incorporate exogenous variables related to intra-day realized measures. The choice of these measures is motivated by the so-called heterogeneous auto-regressive (HAR) class of models. Our augmented model is found to outperform both the Realized-GARCH and the various HAR models in terms of in-sample fitting and out-of-sample forecasting accuracy. The new model specification is examined under alternative parametric density assumptions for the return innovations. Non-normality seems to be very important for filtering the return innovations to which variance responds and helps significantly upon the prediction performance of the suggested model.
Wachstum durch Beschäftigung: Potenziale der deutschen Volkswirtschaft

Published: August 2022

Germany’s labour market faces substantial challenges caused by demographic change in the next decade. However, a country comparison with Sweden and Switzerland reveals hidden labour market potentials. Raising the employment rate towards the Swiss level implies an increase of 1.83 billion labour hours. An alignment of weekly working hours as well as annual working weeks in Germany with the (higher) values of those in Sweden and Switzerland would raise annual labour volume to 4.71 billion working hours. A reduction of involuntary part time work in Germany leads to an increase of 691 million working hours. A better utilisation of the existing labour force potential can thus contribute to tackle the adverse effects of demographic change and enable a state budget consolidation after the crisis.
Do Colletotrichum gloeosporioides and Rhizopus stolonifer induce alkaloidal and antifungal responses in Annona muricata seedlings?
Authors: Riley-Saldaña Christian Anabi , de-la-Cruz-Chacón Ivan , Cruz-Ortega María del Rocío , Castro-Moreno Marisol , González-Esquinca Alma Rosa
Published: August 2022

The benzylisoquinoline alkaloids of Annona muricata have been isolated, but their physiological or ecological role is unknown. The objective was to explore whether these secondary metabolites are involved in defense against phytopathogenic fungi. To do this, the alkaloidal response of 6-leaf seedlings of A. muricata was analyzed, previously inoculated with Colletotrichum gloeosporioides and Rhizopus stolonifer. Before and after inoculation, alkaloidal extracts of roots, stems, and leaves were obtained, and the antifungal activity was evaluated in vitro. The alkaloids anonaine, reticuline, nornuciferine, assimilobine, and coreximine were identified. C. gloeosporioides caused variable increases in the production of anonaine, reticuline and nornuciferine (10–1200%), while R. stolonifer only stimulated the increase of nornuciferin and anonaine (10%) in the stems and leaves. The alkaloidal extracts of inoculated seedlings increased the antifungal activity, both against the pathogen elicitor and against the second target pathogen. These findings suggest that the alkaloids participate in the antifungal defense mechanism.

Geography and Ethnography are intertwined disciplines; therefore, their connection and interaction have always been present in education. The current study approaches geography from an ethnographic perspective, focusing on topographic knowledge. In order to examine the amended documents that regulate public education since 2020 (the National Core Curriculum and the Framework Curriculum), as well as the textbook on ethnography published in 2021, the content analysis method was applied. The study presents how the maps in the textbook expand topographic knowledge and how that constructs the interdisciplinary character of ethnography. The aim is to point out what topographic names appear in the textbook and how this knowledge relates to both fields.
Interlaboratory Test Program to Determine the Precision of the R3 Test Method (ASTM C1897-20) for Measuring Reactivity of Supplementary Cementitious Materials
Authors: Snellings Ruben , Londoño-Zuluaga Diana , Scrivener Karen
Published: August 2022

The substitution of portland clinker by supplementary cementitious materials (SCMs) is one of the main avenues for the further decarbonization of cement production. To secure future SCM supplies, generic and performance-related test methods for SCMs are required. The International Union of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM) Technical Committee 267-Tests for Reactivity of SCMs (TRM) recommended the so-called R3 test methods for SCM reactivity testing and ASTM adopted the test as ASTM C1897-20, Standard Test Methods for Measuring the Reactivity of Supplementary Cementitious Materials by Isothermal Calorimetry and Bound Water Measurements, in 2020. This paper presents the results of an interlaboratory study (ILS) that was carried out to develop precision statements for the ASTM C1897-20 test methods. The ILS was conducted and interpreted according to ASTM C802-14, Standard Practice for Conducting an Interlaboratory Test Program to Determine the Precision of Test Methods for Construction Materials, and precision statements were prepared following ASTM C670-15, Standard Practice for Preparing Precision and Bias Statements for Test Methods for Construction Materials. The ILS involved the testing of three centrally supplied conventional SCMs by both test methods (R3 hydration heat and bound water) by at least eleven labs. The processing and analysis of the ILS data for single-operator and multilaboratory precision are presented.

Geographical distribution and spatio-temporal changes in the occurrence of invasive plant species in Slovak Republic
Authors: Wittlinger L. , Petrikovičová L. , Petrovič F. , Petrikovič J.
Published: August 2022

Biological systems are subject to a dramatic increase in invading species in the 21st century due to increasing globalization around the world. In the near future, these species will cause more extensive ecological as well as socio-economic damage. Biotic invasions will result not only in a reduction of the original biodiversity, but also total loss, particularly degradation of natural habitats – especially Natura 2000 habitats. This study aims to understand the processes of spread of invasive plant species, their way of life, adaptation to environmental changes and displacement of native species. Without the local level, it is not possible to understand these processes on the regional and continental dimensions and thus implement scientific facts and findings into the prediction of the development of global biosystems. The research was conducted during the vegetation period in the years 2017–2021 in the studied areas of non-forest and forest habitats in the central part of Slovakia. We recorded 242 localities in the area with the occurrence of invasive plant species in an area of 3.057 km2 out of the total mapped area of 169.024 km2. We recorded the highest number of localities and the most expansive distribution for the species Stenactis annua, Robinia pseudoacacia, Solidago canadensis, Impatiens glandulifera and Fallopia japonica.

Because of developed symbiotic connections of the root system of trees, mycorrhiza-forming fungi and the orchid family Orchidaceae in forest ecosystems of the northeast Polissia Region – cultivated Pinus sylvestris, which are now 100–120 years old, recovery of cenopopulations of Epipactis helleborine has been observed in locations of mixed and broad-leaved forests. In natural plant cover of mature pines of the region, indigenous vegetation is gradually recovering – there occur young Quercus robur, Tilia cordata, Acer platanoides of various ages, crown density of understory formed by Coryllus avellana has reached 0.6, above-ground organic leaf foliage that is able to sustain moisture and increase fertility of soil accumulates, creating sufficient conditions of shading for seedlings and juvenile individuals of forest orchids. Special studies revealed a relationship between density of E. helleborine specimens and crown density of the tree stand, shrub strata, structure of soil cover, expressed in cenoses under various degrees of recreational pressure. Density of individuals of forest orchids in the studied populations ranges 10.0 to 0.1 ind./10 m2. Dynamics were seen in groupings of Betuleto-Pineta corylosa, Querceta (roboris) corylosa, Querceto-Pineta corylosa, Acereto (platanoidis) –Tilieto (cordatae) – Quercetum (roboris) aegopodiosum in the territory of the nature-reserve fund and structurally similar anthropogenically pressurized cenoses. We determined that all examined cenopopulations in old indigenous zonal cenoses in the territory of the nature reserve fund are normal, they may be considered relatively stable, ontogenetic spectra are incomplete, mostly with right-sided age spectrum – maximum numbers of virgin and generative individuals of various stages. Low density of individuals and incomplete spectra of cenopopulations in light oak forests are natural, and now the largest share of generative and virgin individuals is concentrated in this area. Impact of recreation, unavoidable due to proximity to a road, is a negative factor directly decreasing their density. Ontogenetic spectra of all cenopopulations are incomplete – no seedlings were found in the natural conditions due to underground type of germination. Much more interesting data may be obtained by monitoring studies of age and morphometric dynamic changes during several years.

O presente artigo refere-se a uma revisão sistemática que buscou identificar se a atenção conjunta estabelecida em interações educador-bebê em contexto de creches interfere na cognição social desses bebês. Essa revisão seguiu as recomendações do Preferred Reporting Items for Systematic reviews and Meta-Analyse (PRISMA) e teve as buscas realizadas nas bases de dados Web of Science, Pubmed, Pepsic, Scielo, Indexpsi, PsycInfo e Lilacs. Também se realizou uma busca na Biblioteca Digital Brasileira de Teses e Dissertações (BDTD). Os descritores utilizados foram “Child Day Care Centers”, “Preschool”, “School Teachers”, “infant”, “attention”, “joint attention” e “social cognition”. A análise incluiu cinco artigos e permitiu identificar que ao se engajarem em episódios de atenção conjunta com seus educadores, bebês apresentaram desenvolvimento da comunicação e da linguagem oral. Também se constatou a necessidade de ampliar os estudos sobre o tema. Essa revisão está registrada no International Prospective Register of Ongoing Systematic Reviews (PROSPERO) sob o número CRD42019133759.

We aimed to investigate prevalence and factors associated with Suicide ideation (SI) in mothers of asthmatic children. This cross-sectional study included 362 dyads of mothers and children with asthma aged 2 to 14 years who attended two pediatric outpatient clinics in Brazil. We assessed the presence of SI (Self-Report Questionnaire-20), the occurrence of stressful events and maternal social support. The prevalence of SI was 8.6%. Low maternal education, exposure to serious illness, and low perception of social support in its affective–social interaction dimension remained significantly associated with SI in the final model. Thus, life stressors, social support and low maternal education accounted for most of the variation in prevalence of maternal SI. There were no effects of child asthma severity on maternal SI in this study.
Desafios metodológicos para a elaboração de um banco de dados em estudos de elites políticas

O objeto desta pesquisa é a elaboração de um banco de dados composto pelos deputados federais categorizados pelo Departamento Intersindical de Assessoria Parlamentar (DIAP) entre os anos de 1999 e 2020. Apresentamos o processo de construção do banco de dados e seus impasses metodológicos, buscando: (a) apresentar como o DIAP operacionaliza a premiação dos “Cabeças do Congresso”; (b) apontar as inconsistências presentes nas publicações da série “Cabeças do Congresso”; e (c) expor a relevância das variáveis coletadas neste banco para a compreensão de carreiras políticas e a profissionalização de seus atores. As informações foram coletadas através da base de dados do Observatório de elites políticas e sociais do Brasil, do portal da Câmara dos Deputados, e dos sites do Tribunal Superior Eleitoral e do DIAP. Durante o desenvolvimento do banco foram identificadas inconsistências na série “Os Cabeças do Congresso Nacional”. Por vezes, a atribuição das categorias de destaque dos parlamentares divergia dentro da mesma publicação. A conceituação e o processo de classificação nas categorias de análise também limitam a pesquisa por não estarem bem delimitadas e explicitadas no documento. A estrutura proposta permite conhecer as características e o planejamento de um banco de dados. Este domínio concede boas práticas na construção e coleta de informações aos cientistas políticos, reduzindo divergências e potenciais problemas que possam comprometer o resultado da pesquisa.

Bezugspunkt ist der Begriff des "Küstenbildes", der hier aus unterschiedlichen fachlichen Perspektiven durch deren Vertreter dargestellt wird. Ziel des Bandes ist keine Synthese unterschiedlicher Positionen, vielmehr geht es darum, Divergenzen und vor allem Konvergenzen ausfindig zu machen, die die fachliche Diskussion in Gang bringen könnten. Der in diesem Band vorliegende Pluralismus der Perspektiven auf das "Küstenbild" in den einzelnen wissenschaftlichen Disziplinen und Praxisbereichen ist also durchaus gewollt und stellt interdisziplinäre Ansichten, Ansätze und Konzepte für den Zugriff auf das "Küstenbild" dar.
La paz en Colombia, ¿a cualquier costo?

Published: August 2022

La finalidad del presente artículo es recordar: cuál es la utilidad social de la existencia de las instituciones de justicia o cuál es la importancia de la unión ciudadana en el fortalecimiento de las instituciones jurídicas. Los acuerdos de paz no pueden ser asociados a un debilitamiento de la justicia penal; de allí, la pregunta de investigación: ¿cómo fortalecer la justicia en los acuerdos de paz de Colombia? El estudio parte del axioma: Colombia no es un Estado fallido obligado o sometido a celebrar cualquier acuerdo de paz. Siguiendo un razonamiento lógico-deductivo se concluye que Colombia es un Estado democrático con relativos valores públicos; lo que nos invita a proponer un modelo de elección pública más propio de los mercados competitivos que fortalezca los planes de desarrollo, facilite la perfecta información al votante y se reduzca la corrupción para el bienestar general.

El 4 de julio de 2021 se cumplieron 30 años de la promulgación de la Constitución de 1991: un hecho histórico que marcó el renacer de una Colombia enfrentada a crisis políticas, económicas, sociales, culturales, territoriales, regionales e internacionales. La instauración de un nuevo ordenamiento jurídico se materializó con el objetivo de hacer frente a la debilidad institucional del Estado, la visión centralista y de corto plazo de las élites, la ausencia de procesos de industrialización, la exclusión a minorías sociales y la aparición emergente del narcotráfico y actores armados ilegales.
Cambio tecnológico, automatización, innovación y mercado laboral en América Latina: un nuevo reto para la integración regional

Published: August 2022

Los procesos de integración se han enfocado en crear escenarios para favorecer el intercambio comercial y el flujo de inversiones de los países; sin embargo, los avances tecnológicos implican, entre otras cosas, que no es necesario buscar economías externas para disminuir costos, sino que el uso de ciertas tecnologías también puede hacerlo. En este sentido, las imperfecciones de mercado de las que hablan los teóricos del comercio, y que justifican la expansión de las empresas fuera de sus fronteras nacionales, no necesariamente implicarán la internacionalización del proceso de producción, porque la tecnología disminuiría los costos. Esto genera, entre otras cosas, desempleo tecnológico.

Objective: to assess the effectiveness of a cognitive-behavioral program to control lower urinary tract symptoms after radical prostatectomy. Methods: a randomized clinical trial study, with 41 participants randomized into intervention (n=20) and control (n=21), for three months. The intervention group received the cognitive-behavioral program, while the control group received routine guidance from the service. Outcome variables were urinary incontinence intensity and lower urinary tract symptoms, assessed by the Pad-Test and Urinary Incontinence Scale of Radical Prostatectomy and King’s Health Questionnaire. Results: at the end of the study, the intervention group had a lower urinary incontinence intensity (p≤0.001), and there were less chances of presenting changes in urinary frequency (p≤0.001), urinary urgency (p≤0.001), nocturia (p=0.005), stress urinary incontinence (p≤0.001) and urge incontinence (p≤0.045). Conclusion: the cognitive-behavioral program was effective in reducing lower urinary tract symptoms after radical prostatectomy. Brazilian Clinical Trial Registry: RBR-3sstqg.
