Internal Flow Behaviour and Microstructural Evolution of the Bobbin-FSW Welds: Thermomechanical Comparison between 1xxx and 3xxx Aluminium Grades
Authors: Tamadon Abbas , Pons Dirk J. , Sued Kamil , Clucas Don
Published: July 2021

The influences of processing parameters and tool feature on the microstructure of AA1100 and AA3003 aluminium alloys were investigated using bobbin friction stir welding (BFSW). The research includes flow visualization and microstructural evolution of the weld texture using the metallographic measurement method. Results indicated that the operational parameters of the welding (e.g. feed rate, rotating speed) and the geometry of the tool can directly affect the flow patterns of the weld structure. The microscopic details revealed by the optical and electron microscope imply the dynamic recrystallization including grain refinement and precipitation mechanisms within the stirring zone of the weld region. The microscopic observations for the weld samples show a better performance of the fully-featured tool (tri-flat threaded pin and scrolled shoulders) compared to the simple tool without inscribed surface features. The fully-featured tool resulted in a more uniform thermomechanical plastic deformation within the weld structure along with the precipitation hardening and the homogeneity of the microstructure.

Published: July 2021

Introduction: Colorectal cancer is one of the most common digestive malignancies, with a high mortality and morbidity rate, with nonspecific symptoms in the early stages and with a diagnosis in the advanced stage most often. In a significant percentage there are cases in which tumors with invasion in the border organs and multiorgan resections are required. In women, the invasion frequently occurs in the vagina, uterus and bladder.

Case report: We report the case of a 52-year-old woman, who presented in the Department of Surgery with the following complaints: fecaluria, pneumaturia, constipation and moderate abdominal pain, with onset of 4 months, in wich the patient neglected her symptoms. Following the investigations, a large tumor formation of sigmoid colon was diagnosed, with invasion in the uterus and bladder, with which it communicates through a 16mm fistula. The result of the biopsy was of low / moderate grade adenocarcinoma differentiated G2. Cystoscopy revealed bladder trigone invasion without being able to identify ureteral orifices, biopsy and urine cytology was also positive for cancer. The surgery was performed by a multidisciplinary team and a multivisceral resection was performed.

Conclusions: Multiorgan resections require trained, experienced teams, and oncological pathology raises special issues when it comes to radical visa. The management of invasive colonic tumors in the border organs must be established preoperatively, in agreement with the patient, because it involves problems related to the quality of life and the potential for survival.

Authors: Lozynskyy Roman , Pantyley Viktoriya , Sawicka Anna
Published: July 2021

The article addresses the smart city concept in reference to two neigh-bouring countries – Poland and Ukraine. The paper also analyses various research trends in the scope of the smart city concept, as well as the process and conditions of the concept's implementation in the studied countries. The detailed analysis covered the implementation of the smart city concept in two cities in Poland and Ukraine belonging to neighbouring second-order administrative units, namely Lublin and Lviv. It was determined that both in Poland and Ukraine, the smart city concept is at its initial stage of implementation. This results from a number of different conditions, primarily including the socio-economic transformation of the countries, and inconsistency in reforming different spheres of socio-economic life in Ukraine. Local initiatives (analysed in detail based on the example of the cities of Lublin and Lviv) were determined to be of key importance in the implementation process.

Authors: Darwis Dedi , Junaidi Akmal , Shofiana Dewi Asiah , Wamiliana
Published: July 2021

In this study we propose a new approach to tackle the cropping problem in steganography which is called Center Embedded Pixel Positioning (CEPP) which is based on Least Significant Bit (LSB) Matching by setting the secret image in the center of the cover image. The evaluation of the experiment indicated that the secret image can be retrieved by a maximum of total 40% sequential cropping on the left, right, up, and bottom of the cover image. The secret image also can be retrieved if the total asymmetric cropping area is 25% that covered two sides (either left-right, left-up or right-up). In addition, the secret image can also be retrieved if the total asymmetric cropping area is 70% if the bottom part is included. If asymmetric cropping area included three sides, then the algorithm fails to retrieve the secret image. For cropping in the botom the secret image can be extracted up to 70%.
The role of the spatially fractionated radiation therapy in the management of advanced bulky tumors
Authors: Mahmoudi Farshid , Shahbazi-Gahrouei Daryoush , Chegeni Nahid
Published: July 2021

Spatially fractionated radiation therapy (SFRT) refers to the delivery of a single large dose of radiation within the target volume in a heterogeneous pattern using either a custom GRID block, multileaf collimators, and virtual methods such as helical tomotherapy or synchrotron-based microbeams. The potential impact of this technique on the regression of bulky deep-seated tumors that do not respond well to conventional radiotherapy has been remarkable. To date, a large number of patients have been treated using the SFRT techniques. However, there are yet many technical and medical challenges that have limited their routine use to a handful of clinics, most commonly for palliative intent. There is also a poor understanding of the biological mechanisms underlying the clinical efficacy of this approach. In this article, the methods of SFRT delivery together with its potential biological mechanisms are presented. Furthermore, technical challenges and clinical achievements along with the radiobiological models used to evaluate the efficacy and safety of SFRT are highlighted.
New possibilities of graphics software in the analysis of thermograms of patient’s lower limbs – a technical note
Authors: Wideł Monika , Grzegorczyn Sławomir
Published: July 2021

The analysis involved thermograms of the lower limbs of a patient suffering from symptomatic L-S segment discopathy with spinal root compression syndrome (symptomatic lumbar discopathy) qualified for surgical treatment. The thermograms were obtained using the Flir Ebx 50 camera. They were developed with the use of the software included with the Flir Ebx 50 camera, as well as the Origin Pro 2020 data analysis and graphing software. ROIs (Regions of Interest) were specified and analyzed in terms of temperature (average, maximum or minimum) temperature distributions, isotherms, and specified surface areas limited by selected isotherms. According to the analysis of the thermograms, the images obtained with Origin Pro 2020 enable a more advanced presentation of the temperature distribution, by taking into account the isotherms with selected temperatures and by calculating the area limited by a given isotherm (or between two isotherms) they allow to introduce an additional surface parameter related to specific isotherms. It provides additional information (parameter) in comparison with analogous ROIs on healthy and pathologic limbs in the same patient.
Nature-Based Tourism Motivations and Visit Profiles of Domestic and International Segments to a Japanese National Park
Authors: Jones Thomas E. , Nguyen Minh-Hoang
Published: July 2021

The rapid post-millennial internationalisation of Japan's tourism sector and the influx of international visitors have quickly increased visitor motivations’ heterogeneity, thereby posing challenges for management. Given the lack of prior research, we aimed to identify nature-based tourism (NBT) push-factor motivation domains of visitors in a Japanese national park and segment domestic and international visitors based on their motivations, demographics and trip profiles. Primary data collection of 137 responses took place in November 2019 through an on-site self-administered questionnaire. From 11 push-factor statements, the principal component analysis yielded a four-factor solution: ‘enjoying nature with family or friends’, ‘improving physical health’, ‘discovering and learning’ and ‘escaping’. In addition,t-tests revealed significant differences between domestic and international visitors in three out of the four motivation dimensions. Underlying visitor profiles could explain some such differences. Despite the differences, both international and domestic visitors share similar motivations regarding ‘improving physical health’. These findings hint at the complexity of monitoring heterogeneous visitor segments within Japanese NBT. Despite increasing international visitors, there has been a lack of the necessary infrastructure and facilities to accommodate them. Thus, this study's implications might help diversify NBT management strategies to deal with current shortcomings in Japan's tourism sector.
Migratory Outflow from Wrocław: Directions of Population Flows within the Framework of Internal Migration in the Period 2002–2018
Authors: Długosz Mateusz , Szmytkie Robert
Published: July 2021

In the majority of large cities in Poland there is a migration outflow, resulting mainly from suburbanisation processes. However, it should be noted that the inhabitants of large cities do not move exclusively to the suburban zone. The study below focuses on the migratory outflow of Wrocław residents. The authors characterise it by presenting the directions of population movements and determining their sustainability. The authors conclude that the target area of immigrants from Wrocław is mostly a suburban area, but there are also permanent migration flows to other rural communities in the voivodeship and other large cities in the country. The area of emigration itself goes beyond the scope of the voivodeship of which Wrocław is the capital.
Coastal Regions of Russia: Migration Attractiveness and Innovation Performance
Authors: Druzhinin Alexander , Mikhaylov Andrey , Lialina Anna
Published: July 2021

Coastalisation is a widely known concept that builds on the global urbanisation of the world's marine and ocean coasts. In this paper, the degree of coastalisation of the Russian regions is analysed using a variety of parameters, including population numbers and gross regional products, indicating the accumulation of human activity in the coastal regions against the less densely populated inland territories. This research shows that coastalisation is expected to continue, making coastal regions the most attractive for international and interregional migration, hence their high innovation performance. Based on the principles of human geography, we put forward the hypothesis that Russia's coastal territories are highly heterogeneous in their development dynamics. This study aims to test the interdependence between migration figures and innovation values across 23 regions of Russia with access to the sea. The research design comprises three stages: calculation of innovation performance, evaluation of migration flows and the building up of a typology of coastal regions. The research results reveal an increased migration attractiveness of the country's coastal regions, with the St. Petersburg and Kaliningrad agglomerations and the Black Sea coast of the Krasnodar Krai (region) as the main attractors. Intensive innovation activity is characteristic of St. Petersburg, the northern capital of Russia, whereas peripheral regions where the extractive industries dominate (the Yamalo-Nenets Autonomous Okrug (district), Kamchatka, Krasnoyarsk and Magadan regions) demonstrate a much weaker trend towards combining innovation performance and migration attractiveness.
Estimation of Bare Soil Moisture from Remote Sensing Indices in the 0.4–2.5 mm Spectral Range
Authors: Katarzyna Kubiak , Justyna Stypułkowska , Jakub Szymański , Marcin Spiralski
Published: July 2021

Soil moisture content (SMC) is an important element of the environment, influencing water availability for plants and atmospheric parameters, and its monitoring is important for predicting floods or droughts and for weather and climate modeling. Optical methods for measuring soil moisture use spectral reflection analysis in the 350–2500 nm range. Remote sensing is considered to be an effective tool for monitoring soil parameters over large areas and to be more cost effective than in situ measurements. The aim of this study was to assess the SMC of bare soil on the basis of hyperspectral data from the ASD FieldSpec 4 Hi-Res field spectrometer by determining remote sensing indices and visualization based on multispectral data obtained from UAVs. Remote sensing measurements were validated on the basis of field humidity measurements with the HH2 Moisture Meter and ML3 ThetaProbe Soil Moisture Sensor. A strong correlation between terrestrial and remote sensing data was observed for 7 out of 11 selected indexes and the determination coefficient R2 values ranged from 67%– 87%. The best results were obtained for the NINSON index, with determination coefficient values of 87%, NSMI index (83.5%) and NINSOL (81.7%). We conclude that both hyperspectral and multispectral remote sensing data of bare soil moisture are valuable, providing good temporal and spatial resolution of soil moisture distribution in local areas, which is important for monitoring and forecasting local changes in climate.

S. androgynus (Phyllanthaceae) mengandung senyawa antioksidan alami seperti fenolik dan turunannya flavonoid. Keberhasilan memperoleh senyawa metabolit tanaman bergantung pada metode ekstraksi. Penelitian ini bertujuan menentukan kadar fenolik dan flavonoid dari ekstrak etanolik daun katuk yang diperoleh dari tiga jenis metode ekstraksi yaitu maserasi, Soxhletasi, dan ultrasonik. Penentuan kadar senyawa fenolik dan flavonoid dilakukan dengan metode kolorimetri masing-masing secara berurutan menggunakan reagen Folin-ciocalteu dan AlCl3 10%. Absorbansi hasil reaksi diukur menggunakan spektrofotometer UV-Vis. Kadar fenolik total dinyatakan sebagai kesetaraannya dengan asam galat, sedangkan kadar flavonoid dinyatakan sebagai kesetaraanya dengan kuersetin. Penentuan aktivitas antioksidan ekstrak dilakukan terhadap radikal DPPH dan dinyatakan dengan nilai IC50 (ppm). Hasil menunjukan bahwa metode ekstraksi ultrasonik menghasilkan kadar fenolik (42,96 ± 0,51 mgGAE/g), flavonoid (12,05 ± 0,36 mgQE/g) total dan aktivitas antioksidan (IC50 = 81,43 ± 2,63 ppm) paling baik pada ekstrak etanolik daun S. androgynus dibanding dengan metode ekstraksi lain (maserasi > Soxhletasi). Dengan demikian, dapat disimpulkan bahwa metode ekstraksi ultrasonik merupakan metode ekstraksi yang efisien dan efektif untuk menghasilkan senyawa antioksidan yang tinggi pada ekstrak etanolik daun S. androgynus.

Published: July 2021

Latar Belakang: Puskesmas merupakan sarana yang digunakan untuk meningkatkan derajat kesehatan dan merupakan ujung tombak pembangunan kesehatan. Pelayanan kefarmasian di puskesmas selalu menjadi sorotan dari masyarakat dan cenderung berstigma negatif. Paradigma masyarakat khususnya di Kota Denpasar cenderung menyatakan bahwa pelayanan kefarmasian di puskesmas yang berstandar ISO lebih baik dibandingkan dengan non ISO. Akan tetapi hal ini bukan berarti bahwa puskesmas non-ISO di Kota Denpasar tidak memberikan pelayanan yang optimal kepada masyarakat. Berdasarkan hal tersebut perlu dilakukan penelitian untuk menilai seberapa jauh perbedaan kualitas layanan kefarmasian di puskesmas ISO dan non-ISO Kota Denpasar. Tujuan: Penelitian ini bertujuan untuk membandingkan kualitas layanan kefarmasian di puskesmas berstandar ISO dan non-ISO meliputi waktu tunggu pelayanan obat, angka kejadian Drug Related Problem (DRP), dan tingkat kepuasan pasien. Metode: Sutau studi observasional analitik dilakukan dengan mengobservasi 184 responden yang menggunakan layanan kesehatan puskesmas di Kota Denpasar dengan luaran kualitas pelayanan kefarmasian. Waktu tunggu dilihat dari pasien menyerahkan resep sampai mendapatkan obat, DRP dilihat angka kejadian interaksi obat, kepatuhan pasien terhadap terapi dan kejadian Adverse Drug Reaction (ADR), serta kepuasan pasien menggunakan kuisioner kepuasan. Hasil: Waktu tunggu pelayanan obat menunjukkan bahwa puskesmas ISO lebih unggul dibandingkan non-ISO (p<0,05) sedangkan variabel kejadian DRP dan terkait kepuasan pasien tidak berbeda signifikan (p>0,05). Kesimpulan: Puskesmas non-ISO di Kota Denpasar menunjukkan kualitas layanan kefarmasian yang kompetetif atau sebanding dengan puskesmas berstandar ISO.

USE OF ELECTRODERMAL WRISTBANDS TO MEASURE STUDENTS' COGNITIVE ENGAGEMENT IN THE CLASSROOM
Authors: Terriault Patrick , Kozanitis Anastassis , Farand Patrice
Published: July 2021

A pilot project was conducted to study the feasibility of using electrodermal activity sensors embedded in a watch-like device to measure skin conductivity in real time. In the field of education, it may be interesting to use this technology to assess the students' cognitive engagement in the classroom. A few volunteer students as well as the professor were wearing an Empatica E4 wristband during some class periods where different activities were organized such as lectures, workshops and exams. Monitoring several individuals simultaneously makes possible to compare the collected data among students and between the students and the professor. Also, since the activities were weekly repeated, it was possible to assess to which extent the observed patterns were similar from one group to the other. In brief, the collected data is very difficult to interpret, since some external factors seem to have a significant effect on the measurements. Indeed, discrepancies are observed in the data curves representing the students’ electrodermal activity. Also, the data generated by the professor is quite different from one group to the other, even if he repeated the exact same activities at two different times of the week.  It is suggested to improve the understanding of all the phenomena that could affect the electrodermal activity measurements before trying to draw conclusions related to the students’ cognitive engagement in the classroom.
HANDS-ON EDUCATION WITHOUT THE HANDS-ON? AN APPROACH TO ONLINE DELIVERY OF A SENIOR LAB COURSE IN CHEMICAL ENGINEERING WHILE MAINTAINING KEY LEARNING OUTCOMES
Authors: Ghaemi Roza Vaez , Potvin Gabriel
Published: July 2021

The senior chemical engineering lab course at UBC follows an open-ended problem-based lab (PBL) framework, which has been shown in previous work to improve self-reported learning outcomes in students. Given the hands-on experiential components of lab-based courses in general, their shift to remote delivery, such as the one required by the COVID-19 pandemic, is challenging. Shifting a PBL course to a virtual setting while maintaining its more open-ended learning outcomes is likely even more difficult. This paper outlines the design of an online senior PBL course in chemical and biological engineering, in which TAs, present in the lab, act as Operators and implement student-designed experimental plans over several weeks, while maintaining active virtual contact with their teams. Feedback from students on this experience, the particulars of the course design, and the perceived value of this approach, based on data collected from survey responses, is presented and compared to similar data collected for the latest in-person offering of the same course.

Published: July 2021

Assessment is an essential step in the teaching and learning process. Traditional examination methods (closed-book, time-constrained, invigilated, multiplechoice) prevail in higher education despite support foralternative approaches wherein students construct knowledge through active, authentic activities. A review ofthe scholarly literature focused on merits and limitations of traditional closed-book exams in-person and in anonline, remote course delivery context, as well as benefits, concerns, and considerations of transitioning to open-book exams at a time of upsurge in online learning. Within the dichotomy of traditional versus alterative exam strategies, the literature is inconclusive on shared matters, including student academic integrity, study habits, anxiety, performance, and long-term retention of information.

Authors: Sarandão Susana , Oliveira Ângelo Paiva , Oliveira Isabel
Published: July 2021

Background:

Mycosis fungoides (MF) is a rare type of non-Hodgkin’s lymphoma of T cells that primarily affects the skin. Radiation therapy is a cornerstone of therapy for all stages.

Case Presentation:

A 76-year-old man diagnosed in 2010 with MF in the patch/plaque phase (stage IB T2 N0 M0 B0) was treated with topical corticosteroids and successive sessions of photochemotherapy (psoralen and ultraviolet A) and phototherapy (narrowband ultraviolet B) with relative control of the lesional condition for 9 years. Due to the absence of clinical response and progression of the lesions, it was proposed for the treatment with radiotherapy. The patient underwent total skin electron beam therapy (TSEBT) (6 MeV electron/30/1 Gy per day/4 days per week). The patient showed marked improvement of the lesional condition with minimal toxicity. Remains in follow-up, with good control of the disease to date.

Conclusion:

MF is a challenging disorder from all perspectives. TSEBT in patients with extensive patches or plaques has an excellent response rate and rapid palliation.

Published: July 2021

Indonesia's forest degradation which is triggered by decades of uncontrolled deforestation has caused massive tropical forest depletion. The same situation also happened to Aceh's forest whose forest areas have been shrinking from year to year.  Indication of the increase in illegal logging is both in Indonesia and especially in Aceh as if showing an indication and an academic conclusion that there is a crucial problem. Therefore, there is a need for a mechanism to create an effective legal role to at least reduce illegal logging that is increasingly prevalent in Indonesia's forests. One of the mechanisms is by using a remote sensing technology approach to monitor the occurrence of illegal logging or other criminal acts in the forest which are considered to be the cause of the loss of Aceh's forest in particular and Indonesia in general. This study aims to find out the use of remote sensing satellite technology to monitor illegal logging in Aceh and to identify the use of satellite imagery by law enforcement officials in Aceh to punish illegal logging offenders. The results showed that law enforcement officers used satellite imagery data on conditions before and after environmental damage in handling illegal logging.   However,   the data that emerged from   LAPAN   is rarely used by law enforcement officials to monitor the condition of national forests, especially those in their work areas. Lack of use of satellite data by law enforcement officials in the initial tracking to eradicate illegal logging due to their lack of initiative to prevent illegal logging, the physical condition of  Leuser protected forest areas which are also close to residential areas,   and external issues of areas that make wood from Aceh's forests are traded outside the region and even abroad, as well as the lack of qualifications of law enforcement officials who know the environmental issues.

El staff de prácticas profesionales en Trabajo Social: espacio de fomento del aprendizaje autodirigido. Un estudio de caso en la Universidad Católica Luis Amigó, Colombia
Authors: Blanco-García Cristian Eduardo
Published: July 2021

Las prácticas profesionales son un componente esencial de la formación profesional de los trabajadores sociales, en la consolidación del currículo y en el establecimiento de las relaciones entre el programa, la universidad y el contexto. Mientras que otros estudios se han centrado en los programas presenciales, este texto profundiza en el rol del staff de prácticas como espacio de refuerzo del aprendizaje autodirigido de los practicantes en los programas de educación a distancia. El argumento central de este artículo es que el aprendizaje autodirigido que requieren las prácticas profesionales exige no solo un aprender a aprender, sino también un aprender a hacer desde la recuperación selectiva de saberes previos. El análisis de los resultados muestra que tal recuperación no es sencilla para los estudiantes, por lo que se requieren estrategias adicionales en la supervisión de las prácticas para la obtención de mejores resultados. De otro lado, esta investigación expone que la modalidad distancia no supone un obstáculo para estos aprendizajes.
Fundamentos educativos básicos de la intervención con menores infractores. Revisión crítica a través de un caso “exitoso” en Andalucía, España
Authors: Herrera-Pastor David
Published: July 2021

Este artículo analiza el caso de Rashid, un menor infractor que se convirtió en educador del sistema de protección de menores tras experimentar un proceso de reforma juvenil en España. 
Dicho proceso de reforma juvenil ha sido analizado desde una perspectiva educativa. De manera particular, algunos de los principales fundamentos pedagógicos de su experiencia en el sistema penal juvenil han sido analizados críticamente.
Entrevistas (con Rashid y otros informantes), registros documentales (expedientes e informes oficiales) y registro iconográfico (numerosas fotografías de su proceso de reforma juvenil), además de otras, fueron las principales fuentes y técnicas de recolección de datos empleadas en la investigación.
Según los datos, el condicionamiento fue la estrategia de aprendizaje que prevaleció sobre el resto y la socialización fue el proceso pedagógico dominante durante el proceso de reforma juvenil. A pesar del giro que dio la vida de nuestro protagonista, ninguno de esos dos elementos debería ser considerado fundamento básico de este tipo de intervenciones.
En las conclusiones se revisa el concepto ‘Carácter institucionalizado’ que emerge del estudio. Y, de manera argumentada, se reivindica una aproximación educativa, personalizada y holística más adecuada a la mayoría de casos de este ámbito.

Victimización y perpetración de violencia en pareja adolescente y redes de apoyo en Colombia. Análisis con perspectiva de género
Authors: Reina-Barreto Johanna Alexandra
Published: July 2021

Este estudio analiza la victimización y perpetración de violencia en relaciones de pareja adolescente así como otras variables sociodemográficas comparando al grupo que buscó apoyo social por esta violencia con el grupo que no buscó apoyo. Describe, además, la estructura y densidad de dichas redes de apoyo a partir de una muestra conformada por 2.217 mujeres de entre 13-19 años que respondieron la macro-encuesta de salud Bogotá-2011.Se utilizaron tablas de contingencia con contraste Chi-cuadrado y el coeficiente V de Cramer para comprobar la intensidad de la relación entre variables.
En victimización, el 9% de la muestra sufrió violencia por su pareja masculina y de ellas, el 67,5% no buscó apoyo. El grupo que buscó apoyo informó hasta 19 formas distintas de violencia reportadas por una misma adolescente. A mayor prevalencia e intensidad de la violencia mayor búsqueda de apoyo, sin bien convivir con el agresor disminuyó dicha búsqueda. En perpetración, el 3,2% de la muestra ejerció violencia hacia su pareja masculina agresora. Las adolescentes que más violencia sufrieron no ejercieron violencia perpetraron hacia sus parejas agresoras en mayor proporción. Respecto a las redes de apoyo, la familia fue la principal fuente. Los resultados indican que las mujeres adolescentes experimentan violencia de género en sus relaciones de pareja y que la dominación masculina continúa presente, invisibilizada y legitimada culturalmente en las nuevas generaciones. Se evidencia la importancia de diseñar desde el Trabajo Social políticas sociales e intervenciones que contribuyan a deconstruir las relaciones desiguales antes de iniciarse estas relaciones.
Diagnostic Accuracy of Clusters of Pain Provocation Tests for Detecting Sacroiliac Joint Pain: Systematic Review With Meta-analysis
Authors: Saueressig Tobias , Owen Patrick J. , Diemer Frank , Zebisch Jochen , Belavy Daniel L.

Objective

To assess the diagnostic test accuracy of pain provocation tests for the sacroiliac joint.

Design

Systematic review of diagnostic test accuracy.

Literature Search

Seven electronic databases and reference lists of included studies and previous reviews were searched.

Study Selection Criteria

Studies investigating the diagnostic accuracy of clusters of clinical tests for sacroiliac joint pain were included.

Data Synthesis

Bivariate random-effects meta-analysis was employed. Risk of bias and applicability concerns were assessed using the revised Quality Assessment of Diagnostic Accuracy Studies tool, and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool was used to judge credibility of evidence.

Results

From 2195 records identified in the search, 5 studies were included that assessed clusters of pain provocation tests for the sacroiliac joint. The estimated positive likelihood ratio was 2.13 (95% confidence interval [CI]: 1.2, 3.9), the negative likelihood ratio was 0.33 (95% CI: 0.11, 0.72), and the diagnostic odds ratio was 9.01 (95% CI: 1.72, 28.4). The GRADE ratings for the outcomes were of very low certainty. Assuming a point prevalence of sacroiliac joint pain of 20%, we calculated a positive posterior probability of 35% (95% CI: 32%, 37%) and negative posterior probability of 8% (95% CI: 6%, 10%).

Conclusion

A positive result on a sacroiliac joint pain provocation test cluster gives the clinician 35% certainty of having correctly identified sacroiliac joint pain. Clusters of pain provocation tests for the sacroiliac joint do not provide sufficient diagnostic accuracy for ruling in the sacroiliac joint as the source of pain. Clinicians can rule out the sacroiliac joint as the source of pain with more confidence: the negative posttest probability indicates that the clinician can conclude with 92% certainty that a negative test result is correct.

Hogyan árazza a piac a felelős és fenntartható befektetéseket?
Authors: Timár Barnabás
Published: July 2021

Tanulmányomban azt vizsgálom, hogy igazolható-e az a hipotézis, mely szerint a befektetők szemszögéből pénzügyileg jövedelmezőbb lehet a felelős, fenntartható vállalatokba történő befektetés, azaz nagyobb profit érhető el, mint az ezeket a szempontokat mellőző cégekkel. További feltételezésem, hogy ez a profit növelhető, ha különböző szűkítéseket vagy relatív pontszámokat alkalmazok. Hipotéziseimet a New York-i tőzsde adatain empirikusan vizsgáltam, befektetési stratégiákon (portfólió képzés) és részvényszinten (regresszió) is. A teszteket a teljes piacon, részletes iparági bontásban és csoportosításban egyaránt elvégeztem. A vizsgált mutatókat (ESG, ENV) magukban és relatív megközelítéssel, több időhorizonton is teszteltem. A vizsgálatok nagy részénél nem szignifikáns eredményeket kaptam, néhány iparág esetében látható gyengébb negatív hatás, illetve a regressziók esetében kaptam szignifikáns, de elenyésző gazdasági jelentőséggel bíró koefficienseket. Az időbeni megbontásból látható az ESG és ENV növekvő jelentősége, de a későbbi idősor esetében sem tekinthető szignifikánsnak. Az eredmények arra utalnak, hogy a vizsgált szempontokat a piac egyelőre nem árazza be, így hipotéziseim nem igazolódtak. Ennek oka a Greenwashing-jelenség, vagy az USA fejlett piaca lehet.
Az IFRS 9 prociklikus hatásainak szemléltetése egy, a magyar bankrendszerre végzett szimulációs gyakorlaton keresztül
Authors: Szigel Gábor
Published: July 2021

Az IFRS1 9 számviteli standardnak a prociklikus banki viselkedést erősítő hatása a standard bevezetése óta a viták középpontjában áll. Ezekhez csatlakozva, egyedi megközelítésű szimulációs gyakorlatunkban azt vizsgáljuk, hogy a magyar bankrendszer a 2008–2013 közötti válságepizód során milyen veszteség- és tőkepályával szembesült volna, ha a nemzetközi szinten később elfogadott IFRS 9 már ekkor is hatályos. Ennek során visszamenőlegesen megbecsültük a magyar bankrendszer IFRS 9 szerinti értékvesztését. Az eredmények azt mutatják, hogy az IFRS 9 bevezetése jelentős mértékben előbbre, a válság elejére hozta volna a nagyobb veszteségek számviteli megképzését. Ennek hatására a bankrendszer tőkemegfelelési mutatója a 2008. év végén több mint 20 százalékkal (2,7 százalékponttal) lett volna alacsonyabb (11,8 helyett 9,1 százalék). Emiatt a bankok tulajdonosainak jóval hamarabb kellett volna a valóságban öt válságévre elhúzott tőkeemeléseket végrehajtani, vagy nagyobb mérlegalkalmazkodásra kényszeríteni a bankjaikat. Eredményeink egybevágnak a szakirodalom megállapításaival, miszerint az IFRS 9 bevezetése oly módon növeli a banki értékvesztés prociklikusságát, hogy a veszteségek elszámolását a válságepizódok eleje felé tolja (de nem a válság beköszöntése elé!). Bár az IFRS 9 szimulációnkban bemutatott prociklikus hatása viszonylag nagy, ezt a 2008-as hazai válságepizód különleges mélysége és összetettsége – egyszerre szuverén-, banki és devizahitel-válság – magyarázza. Ebből arra is lehet következtetni, hogy „normál” recessziós körülmények között az IFRS 9 prociklikus hatásai könnyebben kezelhetők.
