Authors: Gurung Govind , Bajracharya Kabindra
Published: July 2020

Introduction: There are not many studies of pediatric trauma in Nepal. Therefore, this study was conducted to find out the visual outcome of pediatric traumatic cataract and causes of poor visual acuity.

Materials and Methods: In this hospital based prospective study, all children visiting the pediatric department of Lumbini Eye Institute and Research Center with traumatic cataract and visual outcome after surgery from July 2018 to August 2019 were evaluated. A total of 136 children ranging from age (0 months to 15 years) with traumatic cataract were included in the study. Data on age of presentation, sex and diagnosis were collected from clinical charts and analyzed.

Results: The study enrolled 136 cases with traumatic cataract. 72.1% male and 27.9% female patients were involved with the average age being 9.46 years (SD 2.95). Final visual acuity was better than 20/60 in 73 percent of the children. Visual acuity was poor in 27 percent of children. In children with poor visual acuity 44 percent of the patients had corneal opacity, 23 percent had retinal detachment and 18 percent had vitreous opacification secondary to trauma. Closed globe injury was seen in 72 percent of children and 28 percent had open globe injury.

Conclusion: Male children were more prone to traumatic cataract than female children. Open globe injury with corneal laceration and opacity was the major cause of decreased visual acuity.
Predatory publishing: A threat to the credibility of science

Published: July 2020

Predatory journals pose a global threat to science. Young scientists and scholars are easy victims of the predatory publications. Predatory publications reduce the accuracy, reliability, and validity of the scientific works published. The predatory publications are worthless, just a waste of time, resources, money, and efforts. Predatory publications undermine the value of legitimate publications. In order to discourage predatory publications, educational and research institutions should set the rules for publication in the journals that must be indexed in web of science, Journal Citation Reports (JCR, Clarivate Analytics, formerly Thomson-Reuters) or other famous scientific databases such as Scopus, DOAJ, PubMed, and MEDLINE. Citation of articles from predatory journals should be discouraged. The students, academics, and researchers should be careful to avoid predatory publications to maintain their credentials.
Challenges and Opportunities in Equitable Distribution of NTFP among the Usufructs of Nepal
Authors: Rawal Rana Bahadur
Published: July 2020

Non-timber forest products (NTFPs) are plants or plant parts that have perceived economic or consumption value sufficient to encourage their collection and removal from the forest. The main objective of this study is to identify the challenges and opportunity in equitable distribution of NTFPs among the usufructs. The study was conducted among the 446 usufructs of Dolpa, Salyan and Banke of Western Nepal. The study had adopted the simple random sampling technique to select the respondent from the study areas. Mixed method approach was applied for data collection. The findings show that there were some challenges due to inadequate knowledge and incomplete information on products, markets and prices on the part of collectors/producers. 54.9 percent of them said lack of the market system of providing price of NTFPs was the key challenges/barriers for the equitable distribution of usufructs followed by dominance of middleman/traders (52.2%), lack of accessibility of big market (45.3%), lack of awareness of price of NTFPs (12.4%) and lack of accessibility to MPIS (6.2%). Though, there were more opportunities to promote the NTFP. Demand of NTFPs mainly comes for three major use categories: 1. Pharmaceutical Industry & Research, 2. Health Care, and 3. Consumer Market. The Government of Nepal should provide the technical skills through training and orientation to usufructs about the proper cultivation and harvesting of NTFP and knowledge on use of MPIS which can directly contribute in the sustainable management of NTFP.

PENERAPAN METODE MULTI ATTRIBUTE UTILITY THEORY (MAUT) DALAM PEMETAAN TINGKAT DAMPAK BENCANA BANJIR DI KABUPATEN BANTUL
Authors: Abdurrahman Afif Irfan , Yuwono Bambang , Fauziah Yuli
Published: July 2020

Flood disaster is a dangerous disaster, an event that occurs due to overflow of water resulting in submerged land is called a flood disaster. Almost every year Bantul Regency is affected by floods due to high rainfall. The flood disaster that struck in Bantul Regency made the Bantul District Disaster Management Agency (BPBD) difficult to handle so that it needed a mapping of the level of the impact of the flood disaster to minimize the occurrence of floods and provide information to the public.This study will create a system to map the level of impact of floods in Bantul Regency with a decision support method namely Multi Attribute Utility Theory (MAUT). The MAUT method stage in determining the level of impact of flood disasters through the process of normalization and matrix multiplication. The method helps in determining the areas affected by floods, by managing the Indonesian Disaster Information Data (DIBI). The data managed is data on criteria for the death toll, lost victims, damage to houses, damage to public facilities, and damage to roads. Each criteria data has a value that can be used to determine the level of impact of a flood disaster. The stages for determining the level of impact of a disaster require a weighting calculation process. The results of the weighting process display the scoring value which has a value of 1 = low, 2 = moderate, 3 = high. To assist in determining the affected areas using the matrix normalization and multiplication process the process is the application of the Multi Attribute Utility Theory (MAUT) method.This study resulted in a mapping of the level of impact displayed on google maps. The map view shows the affected area points and the level of impact of the flood disaster in Bantul Regency. The mapping produced from the DIBI data in 2017 produced the highest affected area in the Imogiri sub-district. The results of testing the data can be concluded that the results of this study have an accuracy rate of 95% when compared with the results of the mapping previously carried out by BPBD Bantul Regency. The difference in the level of accuracy is because the criteria data used are not the same as the criteria data used by BPBD in Bantul Regency so that the accuracy rate is 95%.
In the Spirit of Ubuntu: Educating and Leading Through an African-Centered Paradigm
Authors: Wright Fields Christina
Published: July 2020

Developing college access in high schools for students from marginalized backgrounds (i.e., low socioeconomic status, people of color, and first-generation) is important because these students enroll in postsecondary education at lower rates than White, wealthier, and non-first-generation students. A qualitative case study was conducted to examine how an African-centered charter high school’s personnel, who were teachers and administrators of color, cultivated students’ college-going aspirations while affirming their cultural identities. This study used a social constructivist paradigm to understand how Ubuntu school personnel were active agents in both the school’s college-going culture and African-centered culture. The selected site was an urban public African-centered coeducational charter high school with a postsecondary education focus located in the Northeastern United States. The school has excelled academically both in terms of graduation rates and postsecondary enrollment. The findings suggest that personnel worked collaboratively with each other to develop and foster environments that supported a college-preparatory ethos while simultaneously affirming African Americans and Blacks. They believed that students being successful led to the school being successful, which led to the community being successful, which most importantly led to the Black race being successful. Success began at the individual level but had the potential impact of improving the community and nation as a whole. Personnel believed it was their responsibility to provide students with the necessary social and cultural capital to develop college-going aspirations.

Published: July 2020

The main technological solutions for the current repair of non-rigid pavement in Ukraine are identified. The cost assessment of repair technologies was carried out depending on the cost of arrangement of the pavement and its maintenance. The technical and economic comparison of traditional technologies of current repair of asphalt concrete pavement and technologies of hot regeneration of asphalt concrete is carried out. An expert method and a method of comparison were used in the research. To calculate the comparative economic efficiency, the indicator of reduced costs was taken into account with the risk-free discount rate. Estimate calculations were performed using the software CMETA_8_Online. Based on the analysis of the obtained results, it is established when comparing only the cost of repairs, the most cost-effective methods of renovating the riding qualities of roads are surface treatment and hot recycling technology by the Reshape method. Technologies of hot regeneration of asphalt concrete and arrangement of wear layers from cast emulsion and mineral mixes are cost-effective when carrying out the comparison for interrepair (5 years for current average repair) period.
ON THE METHOD OF DETERMINING LEARNING DESCRIPTIONS TO FORECAST NATURAL DISASTERS WITH THE PATTERN RECOGNITION SYSTEM
Authors: Nelly Tkemaladze  , Violeta Jikhvashvili  , Giorgi Mamulashvili
Published: July 2020

To forecast natural disasters (floods, mud-slides) in the fixed region and in period T0 with SPRL – the System of Pattern Recognition with Learning (elaborated by us) it is necessary to have the data of the previous 12 months of period T0 and learning descriptions (LDs). To identify this latter, the fact of occurrence or non-occurrence of disasters in the same region and the period T0 should be known in other years and also, the above mentioned 12- month date for each year. Determining LDs based on them is the aim of the article. For this purpose, the method which will be included in the first model of the SPRL is elaborated. The SPRL comprises: 1) preliminary elaboration of the initial information, 2) learning and 3) recognition models. This system is implemented on a PC. It is verified on the basis of the real data to recognize objects of different classis. Primary, additional and formal additional parameters are determined in the method given in the article. On the basis of their values in correlation with the aforementioned 12 months two matrices are determined. The first of them corresponds to the fact of occurrence of disasters and the second one – of non-occurrence. By using these parameter values given in these matrices LDs will be determined. The best LDs will be given to the learning model of the SPRL for transformation and increasing of informativity. Based on the LDs obtained after the transformation, the learning model will make knowledge and data bases.

The article proved that pharmaceutical tourism has been developed during a long period of time as an essen-tial part of medical tourism. The defined forms of activity have an integral character and contribute to the in-crease of the level of accessibility and quality of medical and pharmaceutical aid to the population outside their regular place of residence. The preconditions for activation the development of medical tourism and the necessity of being regarded as an independent activity of pharmaceutical tourism have been determined. In-stitutional components of pharmaceutical tourism (a subject, objects, subjects, forms of organization) have been outlined and described as well as the functions, which can be used on two levels: on the level of the government and the society, and in the system of pharmaceutical provision of the population and healthcare in general. The integral and dualistic character of pharmaceutical tourism as a modern activity in the system of healthcare has been substantiated. Taking into account modern tendencies as to globalization of national economics, imperfection of mechanisms of government regulation of the level of accessibility of pharmaceu-tical aid, increase of gap between different countries, groups of population or patients in the resource provi-sion of national systems of healthcare, the need for the development of medical and pharmaceutical tourism will continue in the future. It promotes the development of a complex program of their implementation in Ukraine.

ABSTRACTElections are a means of implementing the sovereignty of the people regulated in the 1945 Constitution. In the implementation of indirect democracy, a representative democratic system is inevitable, so that elections that uphold direct, public, free, secret, honest and fair spirit are a means of regenerating leadership politics to run the government both at central and regional levels. People as the owner of the highest sovereignty surrender their sovereignty to state institutions such as the President, DPR, DPD, and DPRD through elections. After the change in the 1945 Constitution there was a shift in the regulation of popular sovereignty such as the MPR is no longer the executor of popular sovereignty, the implementation of direct presidential elections by the people, until the emergence of the Constitutional Court that can try and decide the president and vice president to stop in his term of office. All of this is an effort to uphold the people's sovereignty and at the same time to maintain the people's sovereignty based on the 1945 Constitution.

Quand et avec quelles conséquences opérer une tumeur neuroendocrine du pancréas ou du grêle ?
Authors: Hain E. , Gharios J. , Sindayigaya R. , Gaujoux S.
Published: July 2020

Les tumeurs neuroendocrines (TNE) sont des tumeurs rares et peuvent survenir dans tout le tube digestif. On distingue les tumeurs fonctionnelles associées à des symptômes secondaires à l’activité sécrétoire de la tumeur et les tumeurs non fonctionnelles. Tout patient présentant une TNE doit être discuté en RCP RENATEN. Concernant les TNE duodénopancréatiques sporadiques, la chirurgie est nécessaire devant une TNE fonctionnelle ainsi que devant une TNE non fonctionnelle de plus de 2 cm, associées ou non à un retentissement canalaire. Pour les tumeurs supposées peu ou pas agressives, il sera toujours privilégié une stratégie d’épargne parenchymateuse afin d’éviter l’insuffisance pancréatique endocrine et exocrine. Concernant les TNE du grêle, la chirurgie doit être systématiquement envisagée, y compris en cas de métastases ou de carcinose associée afin d’éviter une complication mécanique telle qu’une occlusion. Un curage ganglionnaire comportant au minimum huit ganglions doit être effectué. Ce curage doit être large tout en préservant une vascularisation suffisante afin d’éviter la survenue d’un syndrome de grêle court.

Les phéochromocytomes et les paragangliomes sont des tumeurs rares responsables d’une surmorbidité et d’une surmortalité. Au cours de ces 20 dernières années, de nombreuses avancées ont permis de mieux les caractériser sur le plan phénotypique (via l’imagerie métabolique) et génotypique (avec la mise en évidence de nombreux gènes de prédisposition). La prise en charge d’un phéochromocytome ou d’un paragangliome nécessite désormais le recours à un centre expert dès la phase diagnostique. L’objectif de cette revue est de souligner les principales caractéristiques de ces tumeurs, et ce, afin de sensibiliser le clinicien aux différentes étapes permettant d’aboutir à une prise en charge optimale.
Classifications des tumeurs neuroendocrines gastroentéropancréatiques : ce qui change
Authors: Scoazec J.-Y.
Published: July 2020

La classification OMS des tumeurs des organes endocrines, parue en juillet 2017 et celle des tumeurs digestives, parue en juillet 2019, ont introduit plusieurs modifications dans la classification des tumeurs neuroendocrines (TNE) gastroentéropancréatiques, dont la précédente version remontait à 2010. La principale modification est l’introduction d’une catégorie supplémentaire de tumeurs bien différenciées, les TNE G3, qui vient s’ajouter aux deux catégories déjà existantes. Les autres modifications concernent : 1) le seuil de l’index Ki-67 entre TNE G1 et G2, désormais fixé à 3 % et 2) la terminologie proposée pour désigner les tumeurs mixtes : MiNEN (mixed neuroendocrine-non neuroendocrine neoplasm) remplace MANEC (mixed adenoneuroendocrine carcinoma, carcinome mixte adénoneuroendocrine). L’année 2017 a également vu la révision de la classification TNM, qui affine les critères pour la plupart des TNE digestives. Ces différentes modifications doivent être prises en compte dans nos pratiques.
Minestrone Stories
Authors: Kristensen Regnar
Published: July 2020

Serendipity should not be restricted to cutting-edge science and research alone. A proactive approach to the unexpected can also strengthen classes in anthropology and the humanities. But how can you teach if classes are influenced by accidental arrangements and discoveries not sought or considered? I shall tap into two projects of teaching-by-serendipity through indirect cultural exchanges. The two projects in question were named Minestrone Stories, referring to the Italian minestrone soup, usually made of the vegetables available and thereby providing each village in Italy with its own variant. However, the two ‘Minestrone soups’ in question included more ingredients. The teaching-by-serendipity projects targeted what students, teachers and citizens in confined areas of Copenhagen had available, inciting them to indirectly exchange vegetables, songs, services and stories with each other, thus stirring them together. In this article, I reflect on how this stirring provoked an unusual teaching experience and moments of unexpected learning.
Dialogue-based peer learning of educational topics in a university classroom
Authors: Liu Shih-Hsiung
Published: July 2020

This article aims to determine the feasibility of a course on education-related topics based on dialogue-based peer learning (DBPL). According to the literature, the procedures of DBPL are as follows: (1) read texts, (2) formulate individual opinions, (3) express individual opinions in turns, (4) ask and respond to questions, (5) adjust personal opinions. A quantitative survey, an open-ended question on learning perceptions and four paper-and-pencil tests on educational topics were employed to determine the effectiveness of the course for participants’ learning. Most of the participants performed well in the tests and perceived the benefits of the DBPL method for comprehension and for critical thinking on educational topics. The first three steps in the procedure outlined above were identified as key to the results of the study.

University social science instructors sometimes encounter student silence or quarrels around culturally contentious subjects. In a culture that promotes distrust around the issues they teach, how do professors perceive and cope with such difficulties? Preliminary research using qualitative interviews with teachers from two different US universities explores problems they encounter and strategies they employ in the face of student struggles with nuance and a phenomenon referred to here as polarisation anxiety. Professors strategise how to teach the complexity of phenomenon some students have been culturally predisposed to oversimplify, polarise or remain silent about.
Deep structure and geodynamic conditions of granitoid magmatism in the Eastern Russia
Authors: Alekseev Viktor
Published: July 2020

We investigated the deep structure of the lithosphere and the geodynamic conditions of granitoid magmatism in the Eastern Russia within the borders of the Far Eastern Federal District. The relevance of the work is determined by the need to establish the geotectonic and geodynamic conditions of the granitoids petrogenesis and ore genesis in the Russian sector of the Pacific Ore Belt. The purpose of the article is to study the deep structure of the lithosphere and determine the geodynamic conditions of granitoid magmatism in the East of Russia. The author's data on the magmatism of ore regions, regional granitoids correlations, archive and published State Geological Map data, survey mapping, deep seismic sounding of the earth's crust, gravimetric survey, geothermal exploration, and other geophysical data obtained along geotraverses. The magma-controlling concentric geostructures of the region are distinguished and their deep structure is studied. The connection of plume magmatism with deep structures is traced. The chain of concentric geostructures of Eastern Russia controls the trans-regional zone of leucocratization of the earth's crust with a width of more than 1000 km, which includes the Far Eastern zone of Li-F granites. Magmacontrolling concentric geostructures are concentrated in three granitoid provinces: Novosibirsk-Chukotka, Yano-Kolyma, and Sikhote-Alin. The driving force of geodynamic processes and granitoid magmatism was mantle heat fluxes in the reduced zones of the lithospheric slab. The distribution of slab windows along the Pacific mobile belt's strike determines the location of concentric geostructures and the magnitude of granitoid magmatism in the regional provinces. Mantle diapirs are the cores of granitoid ore-magmatic systems. The location of the most important ore regions of the Eastern Russia in concentric geostructures surrounded by annuli of negative gravity anomalies is the most important regional metallogenic pattern reflecting the correlation between ore content and deep structure of the earth's crust.
The age of mineralization of Mayskoe gold ore deposit (Central Chukotka): results of Re-Os isotopic dating
Authors: Artemiev Dmitry , Krymsky Robert , Belyatsky Boris , Ashikhmin Dmitry
Published: July 2020

The article presents the results of the sulfide mineralization dating of the Mayskoe gold ore deposit using the Re-Os isotope system and isochron age estimation method of the main sulfide minerals: arsenopyrite, pyrite, and antimonite. The complex multistage formation of the studied sulfides, as well as the close intergrowths of genetically different mineral phases, did not allow obtaining a single rhenium-osmium isochron corresponding to the formation time of sulfide mineralization. Isochrones for single minerals, collected from each sulfide sample, turned out to be the result of isotopically distinct components mixture (radiogenic crustal and non-radiogenic mantle) and do not make sense from the geochronological point of view. In terms of geology, the most significant result of the study is an age estimation of 128.8 ± 4.4 Ma, obtained for the sulfide mineralization of Mayskoe deposit using Re-Os isotope dating of single fractions of pyrite and antimonite of the ore mineralization stage. While arsenopyrite is most closely associated with gold mineralization, one of the arsenopyrite varieties corrodes framboidal pyrite of the pre-ore stage, has a maximum of the crust component in the osmium isotopic composition and forms a mixing line in the isochron diagram with an apparent formation age of 458 ± 18 Ma. The initial osmium isotopic composition of the studied sulfides indicates a mixed mantle-crust source of sulfide mineralization. The issue of simultaneous ore genesis and granitoid magmatism in the Mayskoe deposit remained unresolved (the age of granitoids according to the U-Pb zircon system is 108 Ma). However, a possible solution could be the further determination of the Re-Os isochron age of the ore mineralization sulphides from the single paragenesis of a specific sample containing both arsenopyrite and pyrite (+ antimonite) with gold.
Theoretical analysis of frozen wall dynamics during transition to ice holding stage
Authors: Semin Mikhail , Levin Lev , Bogomyagkov Aleksandr
Published: July 2020

Series of calculations for the artificial freezing of the rock mass during construction of mineshafts for the conditions of a potash mine in development was carried out. Numerical solution was obtained through the finite element method using ANSYS software package. Numerical dependencies of frozen wall thickness on time in the ice growing stage and ice holding stage are obtained for two layers of the rock mass with different thermophysical properties. External and internal ice wall boundaries were calculated in two ways: by the actual freezing temperature of pore water and by the temperature of –8 °С, at which laboratory measurements of frozen rocks' strength were carried out. Normal operation mode of the freezing station, as well as the emergency mode, associated with the failure of one of the freezing columns, are considered. Dependence of a decrease in frozen wall thickness in the ice holding stage on the duration of the ice growing stage was studied. It was determined that in emergency operation mode of the freezing system, frozen wall thickness by the –8 °C isotherm can decrease by more than 1.5 m. In this case frozen wall thickness by the isotherm of actual freezing of water almost always maintains positive dynamics. It is shown that when analyzing frozen wall thickness using the isotherm of actual freezing of pore water, it is not possible to assess the danger of emergency situations associated with the failure of freezing columns.
Mathematical model of the liquefied methane phase transition in the cryogenic tank of a vehicle
Authors: Didmanidze Otari , Afanasev Alexander , Khakimov Ramil
Published: July 2020

In order to increase the efficiency of using vehicles (VEH) in mining and quarrying conditions, it is necessary to improve the components of gas equipment (cryogenic tank, gas nozzles, fuel supply cryogenic tubes, etc.) for supplying liquefied natural gas to the engine, as well as storage of liquid methane in a cryogenic tank with a long service life. For this, it is necessary to consider the process of heat and mass transfer of liquefied natural gas in a two-phase liquid-gas medium, taking into account the phase transition in the closed volume of the cryogenic tank under consideration.

The article presents a model of unsteady heat and mass transfer of a two-phase liquefied methane medium in a developed two-tank cryogenic tank using a Cartesian coordinate system with fractional control volumes in space.

The experimental data confirm the efficiency of using a cryogenic tank on the VEH platform, in which the run on liquefied methane compared to standard fuels is tripled, the shelf life of liquefied gas in the proposed cryogenic tank is 2-2.5 times longer than in the standard one.
Non-destructive testing of multilayer medium by the method of velocity of elastic waves hodograph
Authors: Potapov Aleksandr , Kondratev Artem
Published: July 2020

The method of velocity of elastic waves hodograph, aimed at non-destructive testing of structurally heterogeneous composite materials and products based on them, as well as multilayer products and constructions, is considered.

The theoretical basis for determining the propagation velocity of elastic waves in a multilayer medium by the hodograph method is given. Based on the studies, recommendations are given for determining the propagation velocity of elastic waves in each individual layer of a multilayer medium, which allows non-destructive testing of the physicomechanical characteristics of each layer of a multilayer medium.

It is shown that in addition to simple multiple reflections in a homogeneous medium, in a multilayer medium with parallel interfaces consisting of two or more layers, complex types of multiple reflected waves and mixed waves (reflected-refracted and refracted-reflected) can arise.

The main task of applying the low-frequency ultrasonic method is to determine the acoustic parameters of the propagation of elastic waves (velocities, amplitudes, spectra). The main methods for determining the elastic wave velocities are considered, based on the hodograph equation of the indicated reflected waves in a multilayer medium.
Landscape monitoring studies of the North Caucasian geochemical province
Authors: Alekseenko Vladimir , Shvydkaya Natalya , Puzanov Alexander , Nastavkin Aleksey
Published: July 2020

The data on the geochemical features of the bedrocks and soils of the province are given. Considerable attention is paid to regional abundances, as well as enrichment and dispersion factors of the chemical elements in landscapes. Using the example of the North Caucasus, it is shown that for such indicators as phytomass, geological, geomorphological, and geobotanical features, it is possible to make a preliminary outlining of regional structures corresponding to geochemical provinces. At the same time, a subsequent geochemical study of these structures remains mandatory. Upon determining certain geochemical associations, geochemical provinces can be basically distinguished; to a large extent, geochemical properties of these accumulated and scattered associations of elements contribute to the regional soil geochemistry. The results of long-term monitoring studies of the North Caucasus geochemical province have shown that the key features of the regional landscapes are due to the composition of bedrock and the presence of a large number of ore deposits and occurrences. The data obtained are the basis for assessing the state of the environment in conditions of increasing anthropogenic impact, and the established regional abundances can be used to assess the degree of pollution in agricultural, residential, and mining landscapes.

Oltre la metafora della guerra Informazione, comunicazione, crisi ecologica nel tempo della pandemia
Authors: Bazzoni Sandro , Pelli Massimo
Published: July 2020

Grandi rivoluzioni nei mezzi di comunicazione di massa si sono succedute in quest'ultimo secolo con velocità impressionante. L'indeboli-mento progressivo dell'agorà, l'espansione vertiginosa dei mass media, e infine la rivoluzione telematica hanno determinato due conseguenze rilevanti nella società. Da un lato hanno creato le premesse per una trasformazione del sapere, che è diventato un prodotto in vendita dell'industria dell'informatica. Dall'altro, la rivoluzione telematica ha fabbricato l'illusione di una collettività iperconnessa nella rete, mentre in realtà sembra sempre più un agglomerato di consumatori solitari, non più in grado di costituirsi come soggetto politico e di incidere sulla realtà. La visione ecologica di Gregory Bateson, che cerca di superare la contrapposizione schismogenetica tra uomo e natura ritrovando la circolarità tra individuo, società e ecosistema, non è diventata parte di una nuova narrazione nella cultura e nel sapere di oggi, ma va tuttora difesa e promossa.

Attraverso spunti teorico-clinici e sulla scia di correnti di pensiero kleiniane e junghiane, gli autori evidenziano alcuni parallelismi tra le reazioni della collettività, collegate alla pandemia, e specifici funzionamenti, di tipo regressivo, che ricalcano i passaggi fondamentali dello sviluppo. Viene proposta una lettura dei differenti destini di alcune terapie on-line a partire da immagini, sogni e trame narrative proposte dai pazienti. In questi contenuti è possibile rintracciare la sottile connessione tra dimensione intrapsichica, interpersonale e collettiva, dove sentimenti di carenza e odio, possono essere onnipotentemente risolti da una iperproduttività, anche tecnologica, che scotomizza il sentimento di impotenza legato al limite e ne impedisce l'elaborazione.

. Le autrici, entrambe psicologhe psicoterapeute impegnate nel Servizio Sanitario Nazionale che prestano la loro opera a favore di bambini e adolescenti, hanno raccolto una serie di impressioni e vissuti dai loro pazienti e da se stesse, durante questo periodo durissimo di lockdown e il successivo allentamento delle misure di contenimento del contagio da Covid-19. In questo lavoro, affrontano il tema dell'onnipotenza e dell'angoscia di morte dal punto di vista dell'adolescente.
Modelli di parent training
Authors: Buonanno Carlo , Muratori Pietro
Published: July 2020

Il bambino sviluppa le proprie abilità e competenze cognitive, emotive e sociali all'interno della relazione con i propri caregiver. In questo contributo verrà preso in esame uno dei possibili modelli di intervento psicoterapeutici che mira a migliorare la relazione fra i caregiver e i propri figli: il parent training. Tale approccio è volto a migliorare l'insieme delle pratiche genitoriali, promuovendo quelle positive e riducendo il più possibile quelle disfunzionali, con l'obiettivo di promuovere il benessere dei figli e di conseguenza, dell'intero sistema familiare. Lo scop o in un programma di parent training è migliorare i livelli di competenza del genitore nel monitorare e gestire il comportamento dei figli e favorire la loro competenza sociale ed emotiva, oltre che allenare a riconoscere e rinforzare i comportamenti positivi del figlio. La letteratura suggerisce l'efficacia di questo tipo di intervento indiretto per numerosi disturbi in età evolutiva. In questo articolo verranno descritti alcuni modelli per i disturbi internalizzanti ed esternalizzanti, scegliendo quelli ritenuti più validi e con un maggior numero di studi di efficacia. Inoltre, anche la terza generazione della terapia cognitiva ha sviluppato nuovi modelli di parent training.

Le famiglie sono messe alla sfida dalla comunicazione della disabilità del proprio bambino. Hanno bisogno di ricreare un nuovo equilibrio per affrontare una difficoltà con un impatto così soverchiante. L'accettazione della disabilità del proprio bambino non è un processo che avviene in automatico. I genitori di bambini con disabilità di grado medio e grave sperimentano alti livelli di stress e di responsabilità, con effetti comparabili a quelli di un evento traumatico. L'Eye Movement Desensitization and Reprocessing (EMDR) permette la riorganizzazione dei ricordi in un modo adattivo e funzionale in accordo ai principi dell'Adaptive Information Processing, riducendo quindi il loro impatto emozionale. L'EMDR promuove un'elaborazione adattiva dell'esperienza traumatica di ricevere una diagnosi e una prognosi negativa riguardante il proprio bambino. Questo lavoro ha lo scopo di indagare l'efficacia di un protocollo di trattamento integrativo di gruppo (EMDR-IGTP). Hanno fatto parte dello studio 39 genitori e il trattamento consisteva in 10 sessioni di gruppo. Sono stati misurati lo stress emozionale, le strategie di coping e la crescita post-traumatica prima del trattamento e tre mesi dopo il termine del progetto, attraverso un confronto tra la media di diverse scale cliniche. Questi risultati preliminari rilevano un miglioramento nei punteggi della Scala della crescita post-traumatica dopo il trattamento. Il lavoro illustrerà il protocollo d'intervento e i risultati

L'obiettivo di questa revisione è identificare metodi efficaci per migliorare l'impegno e l'adesione delle famiglie ai programmi di parent training (BPT). Nonostante la letteratura indichi risultati positivi, spesso le famiglie mostrano uno scarso impegno, fino a giungere a un precoce abbandono del percorso terapeutico. Ciò comporta una serie di conseguenze negative per le famiglie, i clinici, la ricerca e il servizio sanitario nazionale. La letteratura, ad oggi, individua alcuni fattori predittivi del drop-out e varie componenti da includere nei parent training per aumentare l'impegno e l'adesione alle procedure di intervento. Tra strategie di coinvolgimento, alcuni autori suggeriscono l'utilizzo di un promemoria degli appuntamenti, brevi discussioni iniziali sulla necessità di impegnarsi, metodi di coinvolgimento dei sistemi familiari, adattamenti strutturali del programma, incentivi finanziari, aumento del supporto familiare e colloqui motivazionali. Nonostante i programmi BPT abbiano un'elevata efficacia nel cambiamento del comportamento genitoriale, la letteratura evidenzia elevati livelli di drop-out, ragion per cui gli studi presentati hanno piccoli campioni che limitano il potere statistico e la generalizzabilità dei risultati.
Il caso di Viola "insolente e sbruffoncella": un percorso psicoterapeutico multimodale tra lavoro con la bambina e intervento sulla genitorialità
Authors: Ortelli Valentina
Published: July 2020

Il caso clinico presentato è quello di Viola, una bambina di 7 anni con difficoltà comportamentali. Sebbene le manifestazioni non siano severe, non soddisfano, infatti, la diagnosi di disturbo oppositivo-provocatorio, interferiscono sul clima familiare e compromettono il funzionamento scolastico. Vi è un secondo aspetto, inizialmente non esplicitato dai genitori in chiave patologica, che riguarda l'enuresi notturna; tale problematica limita le possibilità di esplorazione del mondo extra-familiare ed è proprio quando emerge la possibilità di fare esperienze con i coetanei, che diventa necessario inserirla tra gli obiettivi terapeutici. In ottica cognitivo-evolutiva e costruttivista, in fase di valutazione è prioritario comprendere il significato interno del sintomo e svelarne la funzione relazionale. Nel caso di Viola è emerso come i comportamenti provocatori fossero il tentativo di controllare in maniera coercitiva gli adulti di riferimento e l'enuresi può essere visto come il sintomo per assicurarsi la prossimità del genitore. Il lavoro clinico è stato favorito da un'ottima collaborazione da parte della coppia genitoriale e buona parte della terapia si è focalizzata su di loro. Grazie alla ricostruzione degli ABC comportamentali in seduta e alla graduale aggiunta di sfumature cognitive ed emotive, i genitori hanno potuto cogliere la funzione relazionale del sintomo e avvicinarsi al mondo emotivo della figlia. L'intervento con la bambina, svolto in parallelo, è stato indirizzato ad una migliore gestione delle proprie emozioni e un lavoro di mentalizzazione in terza persona, finalizzato ad una crescente consapevolezza degli stati mentali altrui.
Fragilità primer
Authors: Infussi Francesco
Published: July 2020

La fragilità territoriale si può forse riconoscere e intendere in modi diversi. Esplorare un suo possibile lessico è una legittima operazione che tenta, più che definirne il centro concettuale, di metterne a fuoco i presupposti, le implicazioni e le associazioni possibili. Esplorare un tema a partire da una ipotesi sulla sua periferia è un modo prudente per circoscriverlo e anche un modo per intendere l'attività di ricerca come una lenta approssimazione alla definizione del suo oggetto. L'autore propone una schematica ed astratta declinazione della ‘fragilità' e ne espone le conseguenze per l'azione progettuale. Lo scopo consiste nella costruzione di una cornice, non prescrittiva ma provvisoria e fragile, entro la quale mettere al lavoro i lemmi che costituiscono il lessico.
Built heritage in disadvantaged contexts: the case of Subotica's synagogue, Serbia
Authors: Camprag Nebojja
Published: July 2020

This article focuses on the case of the synagogue of Subotica, a Serbian city burdened by the rising socioeconomic challenges and emigration. The building was constructed at the peak of industrialization in 1902 by the formerly powerful Jewish minority, when the city was incorporated in the Austro-Hungarian Empire. After nearly four decades of neglect and sporadic restoration works, the synagogue in Subotica was finally fully restored in 2018 with the significant external support. Nevertheless, the declining urban context remains a serious threat to the sustainable management of this monument of international significance.
Silent and expressive buildings in Fieni, a Romanian small industrial town

Published: July 2020

This study focuses on analysing the impact of industrialisation and deindustrialisation processes on the architectural heritage of a small industrial town from Romania, Fieni. The aim is to identify different layers in the architectural landscape in Fieni, a town that was known during communist times at national and international level by its two representative productive activities, the cement and light bulb industries, but touched by the deindustrialisation process after 1990. Nowadays, in the post-industrial period, the town of Fieni faces not only socio-economic consequences, but also architectural ones, with different degrees of conservation and renovation of buildings that question its industrial legacy.
Pedrinhas Paulista. Una colonia di emigranti italiani in Brasile negli anni della ricostruzione postbellica
Authors: Serraglio Riccardo
Published: July 2020

Nel 1952 la Compagnia Brasiliana di Colonizzazione e Immigrazione Italiana istituì la colonia agricola di Pedrinhas Paulista, riservata a lavoratori provenienti dall'Italia. L'architetto Rosario Megna curò la pianificazione urbana e territoriale del nuovo insediamento attenendosi ai principi della razionalità e dell'economia. Nel mezzo del latifondo organizzò un villaggio all'interno del quale erano distinti settori per gli edifici comunitari, per i quartieri residenziali e per gli impianti di trasformazione dei prodotti agricoli. Le case per i lavoratori, sia quelle disposte nell'area urbanizzata sia quelle nelle aree agricole, furono dotate di accessori adeguati alle condizioni locali. Le soluzioni urbanistiche e architettoniche elaborate da Megna hanno posto le basi per il successo della colonia di Pedrinhas, che al giorno d'oggi è una città di circa tremila abitanti sostenuta da una fiorente economia agricola.
