LINGKUNGAN BARU: ADAPTASI BUDAYA OLEH DOSEN CPNS
Authors: Wiradharma Gunawan
Published: January 2021

CPNS lecturers in 2019 at Universitas Terbuka were placed in the head office or in various UPBJJ spreading throughout Indonesia. Some CPNS lecturers are placed in different units from their original regions so they have to make adjustments in the new environments with different cultures. Intercultural communication takes place when there is interaction between an individual with a particular cultural background and other individuals who come from different cultures. Intercultural communication is an important key in the adjustment process. This study explores the adaptation of three UT CPNS lecturers from outside the region. The theory used is Anxiety Uncertainty Management Theory. Descriptive qualitative approach is used to explore the perspective of CPNS lecturers with the local culture. Through this research, the researcher found that there were some important elements that needed to be possessed by CPNS lecturers, namely the cultural adaptation that was carried out, the culture shock that occurred, and the adjustment in the new cultural environment.
Back to structures and signs – remarks on the possibilities of structural aesthetics of music
Authors: Krupińska Eliza
Published: January 2021

Is it possible to talk of mental patterns underlying aesthetic reflections, and has the constant recurrence of particular ideas in the area of aesthetics some deeper explanation? Structural aesthetics of music is an authorial research conception which enables interpretation of phenomena from the area of history of music aesthetics, and in this way provides its systematised picture. The conception uses the ideas of structural linguistics: binary phonological opposition and the historicalliterary process in the approach of Jan Mukařovský. The article also contains an example of using this conception in relation to the aesthetics of antiquity (sophists, Plato, Aristotle), Descartes and impressionism.
Art and emotion: the variety of aesthetic emotions and their internal dynamics
Authors: Przybysz Piotr
Published: January 2021

The aim of this paper is to propose an interpretation of aesthetic emotions in which they are treated as various affective reactions to a work of art. I present arguments that there are three different types of such aesthetic emotional responses to art, i.e., embodied emotions, epistemic emotions and contextual-associative emotions. I then argue that aesthetic emotions understood in this way are dynamic wholes that need to be explained by capturing and describing their internal temporal dynamics as well as by analyzing the relationships with the other components of aesthetic experience.
Koszty uzyskania przychodów w podatkach dochodowych od osób fizycznych i prawnych – specyficzna klauzula generalna czy definicja legalna?
Authors: Münnich Monika
Published: January 2021

Unormowane w ustawach o podatku dochodowym od osób fizycznych oraz podatku dochodowym od osób prawnych koszty uzyskania przychodów od wielu lat w licznych wyrokach zarówno wojewódzkich sądów administracyjnych, jak i Naczelny Sąd Administracyjny, a także w orzecznictwie administracyjnym organów podatkowych i piśmiennictwie podatkowym określane bywają mianem „specyficznej klauzuli generalnej”. Jednocześnie tytułowa instytucja kosztów podatkowych bywa zarówno w judykaturze, jak i literaturze naukowej określana mianem definicji legalnej. Celem artykułu jest jednoznaczne ustalenie tego jaką kategorią prawną jest ten niezwykle ważny element techniczny konstrukcji obydwóch podatków dochodowych w Polsce. Jeden zwrot prawny zakodowany na etapie stanowienia prawa w treści normy prawnej nie może być bowiem interpretowany przez różne podmioty stosujące prawo jednocześnie jako: zwrot niedookreślony, klauzula generalna i definicja prawna. Zjawisko takie jest sprzeczne z obowiązującą pozytywistyczną koncepcją racjonalnego ustawodawcy.
Programowanie i wdrażanie funduszy strukturalnych i Funduszu Spójności w Polsce, Republice Czeskiej i na Węgrzech – efekty i perspektywy
Authors: Szafran Joanna
Published: January 2021

Wśród państw tzw. wielkiej akcesji największymi beneficjentami polityki spójności są Polska, Republika Czeska i Węgry. Wykazywały one szereg podobieństw uwarunkowanych geopolitycznie i historycznie, niższy poziom rozwoju w relacji do UE-15 oraz rosnące zróżnicowania regionalne. Celem artykułu jest ocena skuteczności implementacji funduszy polityki spójności w kontekście niwelowania ich luki rozwojowej i zróżnicowań między regionami. Obejmuje on porównanie systemów programowania i zarządzania funduszami strukturalnymi i Funduszem Spójności w tych państwach w latach 2004–2006, 2007–2013 i 2014–2020 oraz perspektywę po 2020 r. Zmiany w priorytetach alokacji unijnych funduszy są związane z centralizacją ich systemów zarządzania (zwłaszcza na Węgrzech). Ograniczone efekty w konwergencji regionalnej wskazują, że głównymi beneficjentami polityki spójności są dynamicznie rozwijające się regiony stołeczne i metropolitalne, nie zaś najsłabiej rozwinięte. Słaba reprezentacja interesów regionów wynika z braku oparcia w silnej administracji publicznej i ograniczonej samodzielności finansowej. Podstawą analizy są dokumenty programowe, badania literaturowe, dane Eurostatu i urzędów statystycznych badanych państw.
Az 50+ korosztály fogyasztói magatartásváltozásai - egy mélyinterjús kutatás eredményei
Authors: Hegedüs Réka
Published: January 2021

A TANULMÁNY CÉLJAI

Kutatásunk célja, hogy megismerjük az életkor növekedéséből és az életúton történő változásokból adódó fogyasztási és vásárlási magatartásváltozásokat, valamint értékeljük ezek szubjektív érzékelését, különös tekintettel az idősödő korosztályra.

ALKALMAZOTT MÓDSZERTAN

Feltáró kutatásunkban mélyinterjúk formájában kérdeztük az idősödő fogyasztókat (50 év feletti mintán) az életútjuk során megélt és a későbbiekre várt fordulópontokról, az életkorukhoz kötődő kiemelkedő eseményekről, valamint a jelenlegi életkorukhoz fűződő viszonyukról.  Az életúttörténeten belül vizsgáltuk az általuk legfontosabbnak tekintett 5 fordulópont mentén kialakult - szubjektíven érzékelt - fogyasztói magatartásváltozást.

A LEGFONTOSABB EREDMÉNYEK

A mélyinterjúk eredményei alapján a megkérdezett személyek főképp kategorizálva emlékeztek vissza életük fordulópontjaira (iskolák/munka/család/egészség), ezeket igazítva az időrendi sorrendhez. Az életeseményekhez nem minden esetben tudtak konkrét kronológiai életkort kötni, hanem jellemzően életkori sávokban szemléltették a váltások idejét. Átlagosan 8 fordulópontot említettek, mely számot erősen befolyásolja, hogy az adott személy mit tekint fordulópontnak az életében, de leggyakrabban 5 kiemelt, változást hozó életeseményről számoltak be. Ezen változásokat nehezen kötötték össze a fogyasztásbeli változásokkal – általánosítva említettek termékcsoportokat, és jellemzően az újonnan vásárolni kezdett termékcsoportokra emlékeztek az elhagyott termékekkel szemben.

GYAKORLATI JAVASLATOK

Mivel az életút változásaira irányított figyelem kevés teret engedett a megkérdezettek emlékezetében fogyasztói magatartásuk észlelésére, célravezetőbb a vásárlások irányából megközelítve elemezni a fogyasztói kosarak időbeni eltéréseit, majd ezekhez kapcsolni a fordulópontokat vagy életszakaszokat.

Study of the Distribution and Change Law of Stress in Subgrade Immersed in Water in the Hetao Irrigation Area
Authors: Shen Zuo , Jin Li , Xin-zhang Cui , Miao-zhang Yu
Published: January 2021

The Bayan Nur Section of the Jing-Xin Expressway is located in the Hetao irrigation area. In this area, open river flooding is employed to irrigate the farmland, which causes seasonal subgrade immersion. With the fluctuation in the water levels, the water content of the subgrade soil increases, and the soil strength decreases due to water infiltration and capillary action. Thus, a field test section is built for long-term monitoring of the earth pressure, pore pressure, and settlement, and gravel cushion and reinforcement materials are utilized to reinforce the foundation in the test section. The test results show that the tidal variation in the groundwater level is obvious during the irrigation season, with the maximum increase in the pore pressure being 147.7 %, and the highest water level being 0.9 m above the ground. The change of subgrade soil moisture content and subgrade buoyancy results in the change of subgrade base pressure direction. The pressure distribution of the subgrade base after the reinforcement of the sand-gravel cushion and geotechnical materials presents an inverted bell type, which is similar to the pressure distribution of the rigid foundation base. The restraint and tension film effect of the cushion and reinforcement materials helps in improving the rigidity of the subgrade base.

Published: January 2021

Ethanol release was tested in relation to seed vigour measured by seedling emergence and controlled deterioration tolerance in radish, pepper, watermelon, aubergine, leek and onion seed lots. Ethanol release, measured with six lots from each species after four and eight hours at 40°C and 30% seed moisture, was highly negatively correlated with controlled deterioration tolerance (45°C, 48 hours, 20% seed moisture) in radish (r = 0.05, P < 0.05), with seedling emergence in watermelon (r = 0.99, P < 0.01) and to both traits in pepper (r = 0.87 to 0.94, P < 0.05), but not with any variable for aubergine and leek. One single case was significant between ethanol release after eight hours and controlled deterioration for onion seeds. Results indicate that there is a relationship between ethanol release and seed vigour, but this appears to be species dependent.
Prognostic value of PD-L1 expression in bronchopulmonary neuroendocrine tumours
Authors: Rösner Erik , Kaemmerer Daniel , Neubauer Elisa , Sänger Jörg , Lupp Amelie
Published: January 2021

Programmed death protein 1 (PD-1) and its ligand, PD-L1, have emerged as promising therapeutic targets for many types of cancer that overexpress PD-L1. However, data on PD-L1 expression levels in bronchopulmonary neuroendocrine neoplasms (BP-NEN) are limited and contradictory. In the present study, a total of 298 archived, formalin-fixed, paraffin-embedded BP-NEN samples from 97 patients diagnosed with typical carcinoid (TC), atypical carcinoid (AC), small cell lung cancer (SCLC), or large cell neuroendocrine carcinoma of the lung (LCNEC) were evaluated for PD-L1 expression by immunohistochemistry using the highly sensitive monoclonal anti-PD-L1 antibody 73-10. PD-L1 expression levels were semiquantitatively estimated by tumour grading. Of the 298 BP-NEN samples, 85% were positive for PD-L1 expression. PD-L1 immunostaining predominantly localized to the plasma membrane of both tumour cells and tumour-infiltrating immune cells. SCLC and LCNEC exhibited significantly higher PD-L1 expression levels than TC or AC. PD-L1 expression levels were also higher in patients with lymph node or distant metastases, in patients who smoked, and in patients who died during the follow-up period. Moreover, PD-L1 expression levels correlated positively with tumour grading, Ki-67 index and the expression of the chemokine receptor CXCR4 and negatively with the levels of somatostatin receptor 1 and chromogranin A. High tumour PD-L1 levels were associated with poor patient outcomes. In conclusion, PD-L1 expression is common in BP-NEN, increases with malignancy, and is associated with poor prognosis. Therefore, targeting the PD-1/PD-L1 axis could be a promising strategy for treating BP-NEN. PD-L1 may also represent a useful prognostic biomarker for this tumour entity.

Aims

Gestational diabetes mellitus (GDM)-induced macrosomia is predominantly characterized by fat accumulation, which is closely related to adipocyte differentiation. An unknown long noncoding RNA RP11-290L1.3, referred to as RP11, was identified to be dramatically upregulated in the umbilical cord blood of women with GDM-induced macrosomia in our previous study. We conducted this study to identify the function of RP11 in GDM-induced macrosomia.

Methods

The effects of RP11 gain- and loss-of-function on HPA-v (human preadipocytes-visceral) adipogenesis were determined with lentivirus mediated cell transduction. The mRNA and protein expression levels of adipogenesis makers were evaluated by qPCR/Western blot. Then, we performed the microarray and pathway analysis to explore the possible mechanisms by which RP11 regulates adipogenesis.

Results

Overexpression of RP11 significantly enhanced adipocyte differentiation and increased the mRNA and protein expression levels of adipogenesis makers, such as PPARγ, SREBP1c, and FASN by qPCR/Western blot. Knockdown of RP11 showed opposite effects. Microarray and pathway analysis showed, after RP11 knockdown, 1612 genes were upregulated, and 583 genes were down-regulated which were found to be mainly involved in metabolic pathways, insulin signaling pathway and MAPK signaling pathway.

Conclusion

In conclusion, the unknown lncRNA RP11 serves as a positive factor on preadipocyte differentiation which could shed light on fetal fat accumulation in GDM.

A statistically significant higher prevalence of the RET p.Met918Thr somatic mutation, identified by direct sequencing, was previously reported in MTC > 2 cm than in smaller tumors. Aim of this study was to correlate the full RET and RAS mutation profile, identified by a Next Generation Sequencing approach, with the growth rate, proliferation and tumor size of MTC. Data of 149 sporadic MTC patients were correlated with RET mutations and Ki67 positivity. Eighty-one cases had a somatic RET mutation, 40 had a RAS mutation and 28 were negative. A statistically significant higher prevalence of RET mutations was found in MTC > 2 cm. A higher prevalence of RET more aggressive mutations, higher allelic frequencies and, higher percentage of Ki67 positive cells were found in larger tumors which had also a worse outcome. Our study highlights the predominant role of RET somatic mutations in MTC tumorigenesis. We demonstrate that RET mutation prevalence and allelic frequency (AF) are significantly higher in larger tumors. Based on these results, we can conclude that RET mutated C-cells’s growth and proliferation are more rapid than those of non-mutated cells and give origin to bigger and more aggressive MTC.

Published: January 2021

Background: Left posterolateral incision has been a conventional incision for patent ductus arteriosus ligation. This study aimed to evaluate the efficacy and safety of left axillary thoracotomy for patent ductus arteriosus ligation.
Methods: Between January 2013 and December 2019, the clinical data of 76 patients who underwent left axillary thoracotomy for patent ductus arteriosus ligation were compared with the data of a paired group of 101 patients who underwent left posterolateral thoracotomy.
Results: Compared with the left posterolateral group, the left axillary group showed less drainage (P < 0.05). Operation time, postoperative mechanical ventilation time, and postoperative hospitalization duration were similar between the groups. Complications were rare in both groups with no mortality during follow up. In total, 72 patient families (95%) in the left axillary group and 81 patient families (80%) in the left posterolateral group were satisfied with their cosmetic results (P < 0.01).
Conclusions: A left axillary thoracotomy is as safe and effective as a left posterolateral thoracotomy for patent ductus arteriosus ligation. With lower trauma and better cosmetic results, this procedure provides a good alternative to the standard left posterolateral thoracotomy.

Introduction: The coronary arteries, which have to originate from the aorta, may sometimes rise from the pulmonary artery. This study evaluated clinical and diagnostic findings, treatment methods, and follow up of cases with anomalous coronary arteries arising from the pulmonary artery.
Patients and methods: Eight patients with the diagnosis of anomalous left coronary artery from the pulmonary artery (ALCAPA) (N = 6) and anomalous right coronary artery from the pulmonary artery (ARCAPA) (N = 2), between January 2014 and January 2020 from a single center university hospital, were included in the study. Data from patients’ demographic characteristics, electrocardiography, echocardiography, angiographic findings, operation, hospitalization, and follow up were evaluated.
Results: The study included eight patients (six females and two males) – six patients with ALCAPA and two with ARCAPA. The ages of the patients ranged between 3-135 (average: 53.25) months. The median body weight was calculated as 17.4 kg. Severe mitral valve insufficiency was detected in two patients and two other patients had a moderate degree of mitral insufficiency on echocardiography. Ejection fractions ranged between 16-74%. One patient had perimembranous malalignment large ventricular septal defect with pulmonary stenosis. Operative techniques were Takeuchi procedure (three patients), direct implantation (four patients), and left internal thoracic artery to left main coronary artery bypass (one patient). Mechanical cardiac support was not required in the postoperative period. Mortality did not occur. Mitral insufficiency and ejection fractions improved following correction of the coronary anatomy.
Conclusion: It is important to diagnose the ALCAPA or ARCAPA, where the coronary artery originates from the pulmonary artery. Patients should be treated before congestive heart failure and fatal complications occur. Surgical correction should be planned regardless of symptom status, even though some of patients reach adulthood with an increased number of collaterals.

Published: January 2021

Background and aim. Chronic spontaneous urticaria (CSU) is a disease of unknown etiology and autoimmunity has been thought to be an etiological factor. Immunoglobulin E (IgE)-anti-thyroid peroxidase antibodies (anti-TPO) may play a role in the pathogenesis of certain cases of urticaria. The aim of this study is to investigate IgE-anti-TPO in patients with chronic spontaneous urticaria and in patients with Hashimoto’s thyroiditis.

Methods. A total of 175 -subjects were included in this study. 59 patients had chronic spontaneous urticaria without history of Hashimoto’s thyroiditis, while 58 patients had Hashimoto’s thyroiditis without history of urticaria. The control group consisted of 58 participants without history of Hashimoto’s thyroiditis and urticaria. Serum IgE-anti-TPO levels were analyzed by site-directed IgE capture Enzyme-Linked Immunosorbent Assay technique. We used this technique by modifying it.

Results. IgE-anti-TPO antibodies were detected in all three groups and in all subjects. There was no significant difference between the three groups in terms of IgE-anti-TPO levels. Although total IgE and IgE-anti-TPO levels were higher in the IgG-anti-TPO positive chronic spontaneous urticaria, there was no significant difference.

Conclusions. IgE-anti-TPO antibodies do not play a pathogenic role in the majority of patients with chronic spontaneous urticaria.

Today, in order to develop a contemporary society, assimilation of the necessary knowledge and organization of information storage, processing and use are the vital tasks. For this purpose, information data centers are being created, which ensure the realization of these tasks at all levels - from national to individual. Accordingly, location, volume and operation speed of the data centers are changing. Any data center is a fairly costly enterprise, building it "from scratch" requires significant material investments and human resources. Therefore, today researches are aimed at reusing areas and buildings of the out-of-date enterprises and organizations with the exhausted resources, but which, due to the acceptable rate of wear and tear, can be transformed into the innovative enterprises. In Ukraine, it is planned to close a number of coal mines, and, as a result, a significant number of industrial areas suitable for the renovation use will be vacated. Organization of a data center based on the existing facilities of the liquidated coal mine is quite possible and advisable; information about this is given in the article. There are many examples (for example, the Europe's largest data center Lefdal Mine Datacenter in Norway) of the data centers created on the basis of the liquidated industrial enterprises which, after their appropriate adaptation and modification, meet all requirements of the international standard ANSI/TIA/EIA-942. In Ukraine, there are also similar projects (for example, the United DC data center), which can be effectively introduced into the infrastructure of any industrial enterprise to be liquidated. The authors of this article have proven that modern coal mines (in particular, their surface technological complex) are essentially suitable for transformation into a data center due to the existing engineering and transport infrastructure, their favorable location and the required protection. The authors also provide information about the structure of the data center, audit of the surface complex in order to determine "bottlenecks" (non-compliance with the requirements of the ANS/TIA/EIA-942 standard), prerequisites for creating a data center on its basis, principles of calculating degree of depreciation of buildings and areas required for data center layout.

There are various recommendations in domestic and foreign literature regarding the law of distribution of the crushing load along the swing plate of jaw crushers: even, linear or nonlinear. The method of load distribution along the swing jaw affects the resultant crushing force, its application point and, therefore, the forces subjected to the jaw crusher links. A feature of a single toggle jaw crusher is the strong force exerted on the eccentric shaft since the crushing forces are directly transferred to the shaft. Therefore, it is important to determine the worst design case in order to calculate the strength of crusher parts. This article represents the static study of the influence of the application point of the crushing force on the forces acting on the eccentric shaft and the toggle plate of the single toggle jaw crusher. During the study, a kinematic scheme of the mechanism of the single toggle jaw crusher in the form of a four-link crank mechanism was worked out. The dependences of the angles of the rotation of the link on the angle of the eccentric shaft rotation of the crusher were obtained, which allowed determining the trajectories of different points of the swing jaw and the sections of the moving plate which crushed feeding material during the cycle. Static force analysis of the mechanism of a single toggle jaw crusher was carried out which made it possible to understand the mechanism of torque transmission to the links of crusher, determine the forces acting on the toggle plate and the eccentrics shaft bearings, as well as the shifting of application point position of the resultant crushing force along the swing plate during one stroke. The graphs of dependencies of the forces acting on the eccentric shaft and the toggle plate on the position of application point of the crushing load were built, which made it possible to determine the worst case for calculating the strength of crushers’ joints. It is established that maximum forces subjected to the eccentric shaft and the toggle plate occur when the crushing force is applied to the bottom zone of the moving plate. Such an application corresponds to the nonlinear distribution of the crushing load along the swing jaw.
Calculation of the parameters of the hydraulic transport of enrichment waste in polyethylene pipes

In the article, a new method is presented for calculating hydraulic slope and critical speed of cleaning reject hydrotransportation through the polyethylene pipelines, which is based on the Methodology for Calculating Hydrotransport Plants for Tailings Transporting and Inwashing at the Iron Ore Mining and Processing Enterprises. This methodology was approved by the State Construction Committee of the Ukrainian SSR in its Temporary Instructions on Technology of the Tailing Dump Arrangement and was used in the design of all of the waste storage facilities in the Krivyy Rih ore-dressing and processing enterprises. For the conditions of the experiments, it was shown that experimental multiplier in the formula for calculating critical speed of hydrotransportation was depended on the pipeline diameter, free fall acceleration, kinematic coefficient of water viscosity and absolute roughness of the pipe inner surface. The acknowledgement of these factors made an empirical constant in the considered formula dimensionless and close to average value of the constants in the formulas obtained by other similar methods. With the considered method, it is proved that experimental constant in the formula for calculating critical speed of hydrotransportation is inversely proportional to the cubic root of the roughness of the pipeline inner surface, while coefficient of proportionality is a universal constant, which does not depend on the properties of the pipeline material and is equal to 10.1. Therefore, for determining critical speed of hydrotransportation through the polymer pipes by using this method, it is necessary to multiply critical speed for steel pipe with a similar diameter by the cubic root of ratio of roughness of the inner surfaces of the steel and polymer pipelines. It is further shown that value of hydraulic slope significantly depends on the operating coefficient, which shows by how many times coefficient of friction hydraulic resistance in the polyethylene pipe operating in supercritical flow regime exceeds the same value in case of critical flow regime for the same pipe. The research results allowed finding formulas for calculating hydraulic slope and critical speed of the iron-ore cleaning reject hydrotransportation through the polyethylene pipelines, which are based on the dependencies obtained for the steel pipes and value of absolute roughness of the pipeline inner surface.

Published: January 2021

Fever is a condition where the body temperature rises above normal or more than 37o C and also tend to be an initial clinical manifestation of the use of antipyretic drugs thatcause toxicity such as on the liver due to prolonged usage. Particularly, the bangle (Zingiber purpureum Roxb.) is one of the Zingiberaceae plants that contain essential oils used for the treatment of fever. Therefore, this researchaimed to identify active compounds which have antipyreticspotential with the in silico approach. The simulation of molecular docking showed 1,4-naphthalenedione-2-ethyl-3-hydroxy was able to attach to the binding site of cyclooxygenase-2 (COX-2) and interact withmain residues that constituted the active cavity of COX-2. While the simulation of molecular dynamics suggested thatthe bound compound was stable at 4 ns, that is the time taken. The binding free energiesexpected by the MM-PBSA method indicated the 1,4-naphthalenedione-2-ethyl-3-hydroxy had a higher affinity than a native ligand (2-[(2,6-dichloro-3-methyl-phenyl)-amino] benzoic acid, JMS) and paracetamol. This suggested its capacity for advancing as a new COX-2 inhibitor.
Contemporary Management of Urinary Tract Infection in Children
Authors: Mattoo Tej K. , Shaikh Nader , Nelson Caleb P.
Published: January 2021

A state-of-the art review of current literature on UTI in children, with a particular focus on its diagnosis and management by general pediatricians.

Urinary tract infection (UTI) is common in children, and girls are at a significantly higher risk, as compared to boys, except in early infancy. Most cases are caused by Escherichia coli. Collection of an uncontaminated urine specimen is essential for accurate diagnosis. Oral antibiotic therapy for 7 to 10 days is adequate for uncomplicated cases that respond well to the treatment. A renal ultrasound examination is advised in all young children with first febrile UTI and in older children with recurrent UTI. Most children with first febrile UTI do not need a voiding cystourethrogram; it may be considered after the first UTI in children with abnormal renal and bladder ultrasound examination or a UTI caused by atypical pathogen, complex clinical course, or known renal scarring. Long-term antibiotic prophylaxis is used selectively in high-risk patients. Few patients diagnosed with vesicoureteral reflux after a UTI need surgical correction. The most consequential long-term complication of acute pyelonephritis is renal scarring, which may increase the risk of hypertension or chronic kidney disease later in life. Treatment of acute pyelonephritis with an appropriate antibiotic within 48 hours of fever onset and prevention of recurrent UTI lowers the risk of renal scarring. Pathogens causing UTI are increasingly becoming resistant to commonly used antibiotics, and their indiscriminate use in doubtful cases of UTI must be discouraged.

Para el cálculo dosimétrico se usó la metodología MIRD y la representación antropomórfica de los órganos maternos debido a Stabin. La mayor dosis absorbida por la pared uterina y el feto se obtuvieron con el uso del 99mTc-MAG3. El órgano de la biocinética que contribuye con la mayor dosis es la vejiga. La menor dosis absorbida por la pared uterina y el feto se obtuvieron con el uso del 99mTc-DMSA. El órgano de la biocinética que contribuye con la mayor dosis es el "resto" de órganos.

A Psicologia Positiva propõe uma nova abordagem da Psicologia, apresenta o estudo científico das potencialidades humanas e valoriza os aspectos positivos. O presente estudo tem como objetivo investigar a produção científica na área de Psicologia Positiva e sua utilização no contexto do trabalho. O estudo consiste em uma revisão sistemática dos artigos dos últimos 5 anos nas bases de dados Scielo, Pepsic e Lilacs, com os seguintes descritores: “Psicologia Positiva” e “Trabalho” no idioma português, Psicologia Positiva e trabalho no idioma inglês e Psicologia Positiva e trabalho na língua espanhola. De acordo com os critérios de inclusão, 13 artigos foram avaliados nesta revisão. Os resultados mostraram que a maioria dos estudos selecionados abordou a aplicação e o desenvolvimento de escalas que utilizam a Psicologia Positiva; a escala de Engajamento é a mais utilizada, com prevalência de 38%. Na revisão sistemática, foi possível confirmar a qualidade das escalas desenvolvidas e validadas. Conclui-se que o uso de constructos de Psicologia Positiva é relevante nos contextos de trabalho.

A adaptabilidade de carreira é um tema amplamente estudado na área de carreira por sua relevância prática e teórica. O objetivo deste estudo foi testar uma versão em português brasileiro da Career Adapt-Abilities Scale (CAAS) com uma amostra de adolescentes, incluindo uma dimensão adicional chamada cooperação. Participaram 592 adolescentes (303 do sexo feminino) de escolas privadas (n=275) e públicas (n=317), em Porto Alegre, RS. Os adolescentes tinham entre 13 e 18 anos (M=15,91 e DP=1,08). Em uma primeira subamostra aleatória (n=296), uma análise fatorial exploratória foi conduzida e resultou em uma solução de cinco fatores. Logo após, com o restante da amostra, foi realizada uma análise fatorial confirmatória, confirmando-se o modelo de cinco dimensões. Os resultados indicam que o instrumento testado possui uma estrutura dimensional compatível com o modelo teórico adotado e propriedades psicométricas aceitáveis, além de contar com o acréscimo da dimensão cooperação.

A tipologia circadiana é uma dimensão comportamental associada a preferências de hábitos diários. Contudo, este estudo objetivou avaliar a qualidade de sono e a sonolência excessiva de acadêmicos de Psicologia. Participaram deste estudo quase-experimental 56 estudantes com idade entre 17 e 34 anos. Utilizaram-se como instrumentos o Índice de Qualidade de Sono de Pittsburgh (PSQI), o Questionário de Matutinidade e Vespertinidade, a Escala de Sonolência de Karolinska e a Escala de Ritmo Social Breve. Após avaliar o PSQI, todos os participantes responderam os instrumentos por um período de 14 dias consecutivos. A MANOVA mostrou diferença significativa para sonolência diária durante os dias úteis [λ=0.81; F(4;47)=451,53; p<0,05], especificamente para o horário das 21h [F(2;5)=3,03; p<0,05]. Conclui-se que os estudantes possuem qualidade de sono ruim e, geralmente, tentam compensar as faltas de noites de sono durante a semana nos finais de semana.

Este estudo teve por objetivo avaliar o repertório de habilidades sociais de estudantes de Ciências Exatas antes e após uma disciplina de Relações Interpessoais. Participaram deste estudo 21 universitários, sendo 17 do curso de Engenharia Elétrica e 4 de Química Industrial, matriculados na disciplina de Relações Interpessoais para o Curso de Engenharia Elétrica. A disciplina teórico-prática foi baseada em vivências e os estudantes responderam ao Inventário de Habilidades Sociais (IHS) e ao Questionário de Avaliação Final da Disciplina (QAFD). Os resultados apontaram diferenças estatisticamente significativas quanto ao escore geral de habilidades sociais e a média no QAVD entre as avaliações do pré e pós-teste. Foram observadas ainda correlações positivas e fortes entre o QAVD antes e após a disciplina. Além disso, (b) o escore geral QAVD após a disciplina se relacionou positiva e moderadamente com o escore geral (IHS) de habilidades sociais no pós-teste.

Published: January 2021

A Inteligência Emocional (IE) é um construto psicológico amplamente divulgado nas últimas duas décadas, principalmente fora do meio acadêmico, mas requer uma maior diversidade de pesquisas científicas que contribuam para sua solidificação. Portanto, este trabalho buscou analisar a relação de IE com Inteligência (G), idade, sexo, renda familiar, escolaridade e Habilidades Sociais (HS). Participaram 120 pessoas, entre 18 e 61 anos de idade, de ambos os sexos, que responderam aos testes de percepção e de compreensão emocional, raciocínio abstrato e verbal e habilidades sociais. Os resultados encontrados indicaram correlação significativa positiva entre IE, G e escolaridade, negativa entre IE e idade, nenhuma correlação entre IE, HS e renda familiar e nenhuma diferença entre homens e mulheres para IE, sendo o raciocínio abstrato a variável mais preditora do construto. Tais informações auxiliam para uma melhor compreensão da IE e da sua relevância atual.

O objetivo desta pesquisa foi obter dados normativos de um conjunto de faces do Karolinska Directed Emotional Faces (KDEF) em uma amostra brasileira. Para isso foi utilizada uma amostra não probabilística (por conveniência) de 100 participantes da cidade de João Pessoa-PB. Esses tinham idades entre 18 e 62 anos (M=21,6; DP=6,2), a maioria do sexo feminino (76%). Os resultados mostraram que os participantes obtiveram um percentual de acerto médio de 76,2%, de modo que expressões de Alegria (94.7%) e Surpresa (90.3%) foram as emoções mais facilmente identificáveis e Medo (40.65%) a mais difícil. Em relação às medidas de intensidade e valência, Nojo seguida de Surpresa obtiveram classificações mais intensas, e Alegria foi a única emoção com valência positiva alta. Esses achados foram bastante similares com àqueles relatados em pesquisas anteriores, fornecendo normas subjetivas de classificação mais adequadas às características da população brasileira.
Online psychotherapy practice by psychodynamic therapists

Published: January 2021

Online psychotherapy was recognized by the Federal Council of Psychology Resolution n. 11/2018. With the official recognition of this practice, many professionals raised questions about its equivalence to face-to-face psychotherapy and the possible need of technical adaptations. Considering the lack of research on this theme, this study aimed to explore how psychodynamic/psychoanalytical psychotherapists perceive their own practice in online settings, including technical and relational aspects of the therapeutic process, in comparison to their experience in face-to-face treatments. This is a qualitative study with an exploratory approach. Eight psychologists responded to videoconference interviews. The interviews were audiotaped, fully transcribed, and analyzed by thematic analysis. Results were organized in two major themes (online psychotherapy practice and technique and psychodynamic process in online psychotherapy). Main results indicate online psychodynamic psychotherapy has many distinctive features (e.g. relying on quality of internet connection, fostering focal process, occurring in a more vulnerable setting, and eliciting a different pattern of communication) that require adaptation from therapist. Implication of findings to psychotherapy training and practice are discussed.
POLÍTICAS PÚBLICAS: DE LA TEORÍA A LA PRÁCTICA
Authors: Camacho Monge Daniel
Published: January 2021

Un rasgo importante de las políticas públicas es que contienen planes complejos y coherentes de mediano o largo plazo, tienen como objetivo a la totalidad de la población o sectores amplios de ella y, por lo menos en la teoría, buscan el bien común. Para su ejecución requieren instrumentos, tales como, la promulgación de normas (leyes, reglamentos, directrices y otros instrumentos jurídicos) recursos financieros, recursos humanos y un grado considerable de legitimidad, entendida como la aceptación y el apoyo por parte de un sector significativo o por la totalidad de la ciudadanía.

Demography and well-being
Authors: Clark Andrew E.
Published: January 2021

Demography studies the characteristics of populations. One such characteristic is well-being: this was the subject of the 2019 Wittgenstein Conference. Here, I discuss how objective well-being domains can be summarised to produce an overall well-being score, and how taking self-reported (subjective) well-being into account may help in this effort. But given that there is more than one type of subjective well-being score, we would want to know which one is “best”. We would also need to decide whose well-being counts, or counts more than that of others. Finally, I briefly mention the potential role of adaptation and social comparisons in the calculation of societal well-being.
