BODY COMPOSITION AND HAND GRIP STRENGTH IN HEALTHY COMMUNITY-DWELLING OLDER ADULTS IN SWEDEN
Authors: Lindblad A. , Dahlin-Ivanoff S. , Bosaeus I. , Rothenberg E.
Published: December 2021

Background: Longevity increases worldwide but there are few studies on body composition and hand grip strength in populations over 80 years. Given high prevalence of chronic disease and functional disability in octogenarians, it may be difficult to distinguish effects of ageing from those imposed by disease. The European Consensus definition of sarcopenia recommends using both low muscle mass and function for diagnosis. Objectives: Examine body composition and hand grip strength in a selected group of community-dwelling older adults with high level of functional independence. In addition, longitudinal changes in handgrip strength were examined using previously collected data. Design: Cross-sectional body composition and hand grip strength with a four year retrospective analysis on previously assessed hand grip strength. Setting: Measurements were conducted by home visits. Participants: 102 community-dwelling 83-96 year-olds, 50 % women. Measurements: Hand grip strength was registered by a dynamometer and body composition analysis using bioimpedance spectroscopy. Results: According to European Consensus definition, only 6/102 had normal muscle mass - no men, although 78 % of men and 40 % of women had normal muscle strength. Since previously collected data four years earlier, men had lost strength (p<0.001), while women had not (p=0.202). Conclusions: Subject characteristics and health status support well-preserved body energy, protein stores and muscle strength. Low muscle mass was much more prevalent than low muscle strength. Results may give an indication of what constitutes a healthy body composition in oldest old and could serve as a starting point for reference values on healthy body composition in octogenarians.
Cointegration FDI to Economy Growth
Authors: Sudibyo Ivan
Published: December 2021

The contribution of foreign direct investment to economic growth is perhaps one of the most studied topics in academic research over the past five decades. However, few studies have examined both the short-term and long-term effects of this impact on developing and emerging markets, particularly during times of economic uncertainty including the financial crisis. global financial crisis. This paper examines the relevant quantitative evidence on the impact of foreign direct investment (FDI) and outward foreign direct investment (OFDI) on economic growth by the regression method and the Johansen cointegration test.
La región de la maquinaria agrícola en la Argentina reciente
Authors: Seval Martín
Published: December 2021

La relevancia económica de la producción de maquinaria agrícola la posicionó como caso testigo de una estrategia de desarrollo desplegada por el Estado nacional argentino para impulsar la construcción de regiones productivas. Sin embargo, la borrosidad de los conceptos del discurso nuevo-regionalista que subyace a esta estrategia significó serias dificultades para advertir las lógicas de territorialización en el marco de este tipo de regiones. El presente artículo tiene por objetivo analizar en profundidad el primer decenio (2006-2015) de la construcción regional impulsada en torno a esta actividad, para problematizar la relación entre su institucionalidad y espacialidad. Esta propuesta recupera cruces teóricos entre el debate sobre el desarrollo, el debate regional y el debate territorial y plantea una secuencia metodológica de análisis. En el caso de estudio, esta secuencia permite identificar las fortalezas de su territorialización y visualizar las fragilidades derivadas de la territorialización precaria por selectividad actoral y fragmentación espacial, a los fines de ponderar las posibilidades de reversión en la actualidad.
Using a Headshot Assignment to Incorporate Critical Theory Into Photojournalism Classrooms
Authors: Briscoe Andrea , Lough Kyser
Published: December 2021

This case study uses a diversity and critical thinking exercise in a photojournalism class to show how journalism educators can incorporate race and gender conversations about ethics and judgment into traditionally skills-oriented courses. It is crucial that journalism students learn how to apply their skills properly in an era of social unrest, inequality, and dwindling media trust. Democratic citizenship and journalism are intertwined, but often the bigger ethical conversations are left out of skills-oriented courses. This can lead to a disconnect between the skills themselves and the responsibility of practicing the skills, especially when it comes to matters of power and representation. The field of photojournalism remains predominately White and male, which makes it all the more crucial for students to interrogate their own biases to ensure ethical coverage of their communities. The assignment asks students to make 36 portraits of strangers, and the subsequent classroom exercise has them confront their inherent biases by looking at the demographics of the people they photographed compared to the general population. Data for this case study consist of observations of the classroom conversations and a reflexive journalism exercise the students completed afterward. Findings indicate this exercise is a successful way to introduce racial and gender considerations as part of photojournalistic ethics and judgment. Students initially neglected to think about representation and diversity in their selection of people to photograph but afterward said they could effectively incorporate reflexivity into their work in an effort to provide more representative imagery and confront their own biases.
Unresolved: Public Speaking Instruction Beyond Persuasion
Authors: Edwards Jonathan
Published: December 2021

This essay advocates the use of “unresolved” speech assignments in introductory public speaking instruction. Unresolved speeches work to decenter persuasion in the speech class by asking students to critically explore the landscape of arguments surrounding controversial topics and issue questions without making the turn to opinion giving and persuasion.
Realms Without Totality
Authors: Holland Kristopher
Published: December 2021

This essay posits tensions in art, education, and politics by using philosophical discourse to suggest that the way to create transformative events for social change is to understand Lyotard's diagnosis of the current age and Rancière's call to critical art practice. By proposing new strategies and tactics such as 'post-art' and 'strange tools', the author tries to demonstrate in the text the indirect approaches advocated by Lyotard and Rancière in tackling the current post-political world.

Published: December 2021

Stocks are an investment that attract people because they can earn large profits by having claim rights to the company's income and assets so investors have to observe stock price movements in the future to achieve investment goals. One of the statistical methods for time series data modeling is ARIMA. However, modeling assumptions must be fulfilled to use that method so an alternative model is proposed, namely nonparametric regression model, which has no modeling assumptions requirement. In this study, the nonparametric regression multiscale autoregressive (MAR) with two different filter and decomposition level J are compared to choose the best model and forecast it. The data are closing stock price, high stock price and low stock price of BBRI’s stocks that divided into 2 parts, namely in sample data from March 19, 2020 to February 4, 2021 to form a model and out sample data from February 5, 2021 to March 23, 2021 used for evaluation of model performance based on MAPE values. The chosen best model for each stock price are the MAR model with  wavelet haar filter and decomposition level 5 for the closing stock price which produces a MAPE value of 1.194%, the MAR model with wavelet haar filter and decomposition level 5 for the high stock price which produces a MAPE value of 1.283%, and the MAR model with a wavelet haar filter and decomposition level 5 for the low stock price which produces a MAPE value of 1.141%, indicating that the models have excellent forecasting capability. In this study, Graphical User Interface (GUI) using R software with the help of shiny package is also built, making data analyzing easier and generating more interactive display output.

Published: December 2021

Indonesian people’s awareness of the importance of health has increased significantly so that it has a positive impact on the development of the health sector in Indonesia. The largest service facility in Central Java Province is RSUP Dr. Kariadi. The number of patients who came for an examination at Dr. Kariadi’s arrival rate is unpredictable. This can cause the service system to be busy and result in queues. The purpose of this study was to find out how the service system in Dr. Kariadi especially eye polyclinic, ENT polyclinic, laboratory, and registration. Queue theory has random arrivals and services. Bayesian method is used to analyze the queue system, that has been running for a long time by combining the prior and likelihood distribution of samples. Prior distribution is obtained from previous research, namely the Poisson distribution. Meanwhile, the likelihood of the sample obtained from the current study is the Poisson distribution and the Negative Binomial distribution. The resulting queue models for the eye polyclinic are (GAMM/BETA/4):(GD/∞/∞), ENT polyclinic (GAMM/GAMM/2):(GD/∞/∞), laboratory (GAMM/GAMM/4):(GD/∞/∞), and registration (GAMM/GAMM/3):(GD/∞/∞). Based on the results of the study, it was found that the patient care system at the eye polyclinic, ENT polyclinic, laboratory, and registration met steady state condition, meaning that the service system was running well. The value of the unemployment rate at the eye polyclinic is 96,36%; ENT polyclinic 31,86%; laboratory 34,87% and registration 32.85%. Thus, at the eye polyclinic, the unemployment rate is greater than the busy level. Meanwhile, in ENT polyclinics, laboratories, and registration is the opposite occurs.

Authors: Khasanah Nurul , Sugito Sugito , Wilandari Yuciana
Published: December 2021

Tirtonadi is the largest bus station in Surakarta City. The departure line is devided into two lines, namely west line and east line. The west line serves buses to the west of Surakarta City. The number of buses that enter and leave the station every day causes bus queues. Modeling the queue system and analyzing the system performance measure aims to determine wether the bus service system is good or not. The queue system model is obtained by finding the distribution of arrival patterns and service patterns using the Bayesian method. This method is used because it combines the information from the current research and the prior information from the previous research. The queueing condition of the five lanes in the west line meets steady state conditions because the utility value is less than 1. The queue displant is First Come First Service (FCFS) with unlimited customers and unlimited calling sources. Based on the posterior distribution, the queue system of service bus is (GAMM/IG/1):(GD/∞/∞) for Solo-Jakarta-Bandung lane and Pedesaan lane, while for Solo-Purwokerto-Cilacap, Solo-Yogyakarta, and Solo-Semarang has the queue system (GAMM/GAMM/1):(GD/∞/∞). The queue system of service bus for each lane has good services based on the value of system performance measure.

Im Beitrag Radikalisierung im Geiste des Nationalen, oder: wie aus einem Anti-Revolutionär ein Reaktionär wurde. Zu Ingo Schulzes Die rechtschaffenen Mörder (2020) wird der Versuch unternommen, das Brexit-Phänomen in den allgemeineuropäischen Kontext der Kristallisation von populistischen und nationalistischen Bewegungen im Europa des 21. Jahrhunderts sowie der krisenbedingten Radikalisierung der heutigen Gesellschaften einzuordnen. Im Vordergrund der Überlegungen steht zwar die schmerzhafte Erfahrung der deutschen Teilung und der ebenso problematische Prozess der Wiedervereinigung nach 1990. Doch die Platzierung der Analyse dieses Phänomens im Rahmen einer kulturwissenschaftlich orientierten Literaturwissenschaft lässt zu, die universellen Kategorien für seine Beschreibung wenigstens ansatzweise herauszuarbeiten. Gemeint sind u.a. das Gefühl der Deprivation und der Orientierungslosigkeit, die Herausbildung einer negativen Vorstellung des Fremden als Folge von Angst vor dem Identitätsverlust sowie die Anfälligkeit für den Populismus.
„BrexLit” po włosku dla dzieci i dorosłych: Rosie e gli scoiattoli di St. James oraz La mia Londra Simonetty Agnello Hornby
Authors: Rygielska Małgorzata
Published: December 2021

Artykuł poświęcony jest porównaniu dwóch książek Simonetty Agnello Hornby ze szczególnym uwzględnieniem tematyki migracyjnej, którą autorka, urodzona w 1945 roku we Włoszech, a od 1972 roku mieszkająca na stałe w Wielkiej Brytanii, poruszała także w innych utworach. La mia Londra to autobiograficzny przewodnik po Londynie, w którym Hornby opisała na własnym przykładzie przebieg procesu adaptacji do życia w kulturze innej niż rodzima. Spędziła w tym mieście prawie pół wieku, z perspektywy czasu zwracając uwagę na zmiany, jakie zaszły m.in. w strukturze społecznej, relacji z imigrantami, stylu życia londyńczyków. Główną bohaterką opowieści dla dzieci Rosie e gli scoiattoli di St. James jest Rosalia Giuffrida-Watson, dziewięcioletnia córka londyńskich imigrantów (Włocha Bruna i Jamajki Brendy), która w dzień referendum dotyczącego pozostania Wielkiej Brytanii w Unii Europejskiej staje się świadkiem obrad parlamentu zwierząt w parku królewskim, a także walk jego mieszkańców: przybyszów i autochtonów. Ich poglądy, zachowania i decyzje pozwalają Rosie zetknąć się z problemami, ale i potencjałem, jakie niosą ze sobą procesy akulturacji, adaptacji kulturowej, a nawet – asymilacji. Tłem porównawczym dla rozważań są inne utwory wpisywane w nurt BrexLitu.
Piekło wiralu. Środkowoeuropejskie dystopiczne wizje mediów społecznościowych
Authors: Filipowicz Marcin
Published: December 2021

Wiele demokratycznych krajów w trakcie ostatniej dekady zostało zaskoczonych własnym nieprzygotowaniem na zagrożenia płynące z upowszechnienia się mediów społecznościowych. Inwigilacja, dezinformacja i propaganda czy też mowa nienawiści, to wszystko stało się realnym zagrożeniem, wywołanym przez największe platformy społecznościowe. Literatura również zareagowała na to zjawisko, przede wszystkim dostarczając dystopicznych wizji dalszego niekontrolowanego oddziaływania mediów społecznościowych. Artykuł skupia się na analizie i interpretacji dwóch wydanych w ostatnim czasie na gruncie czeskiej i słowackiej literatury powieści – czeskiego pisarza Davida Zábranskiego Logoz aneb Robert Holm markéter dánský (Logoz czyli Robert Holm duński marketingowiec, 2019) i słowackiego pisarza Michala Hvoreckiego, Troll (Troll, 2017). Istotą interpretacji jest szukanie odpowiedzi na pytanie, czy literatura ogranicza się w tej kwestii wyłącznie do snucia apokaliptycznych wizji, czy też może pokazuje ewentualne plany naprawcze.
Koszty obecności spółki na rynku NewConnect i ich postrzeganie przez emitentów
Authors: Śliwiński Paweł , Woźniak Sonia
Published: December 2021

Celem artykułu jest analiza kosztów obecności spółek na NewConnect oraz zbadanie ich postrzegania przez notowanych na tym rynku emitentów. Hipoteza poddana weryfikacji w artykule zakłada, że koszty obecności spółek na rynku NewConnect są wysokie z punktu widzenia notowanych na tym rynku spółek. Taka percepcja kosztów może ograniczać rozwój NewConnect przez negatywne postrzeganie tego rynku bezpośrednio przez emitentów, a pośrednio również przez inwestorów i media. Weryfikację hipotezy przeprowadzono z wykorzystaniem badań ankietowych przeprowadzonych wśród spółek notowanych na rynku NewConnect. W badaniu ponad 70% spółek uznało koszty obecności na NewConnect za zbyt wysokie. Biorąc pod uwagę, że nastawienie do kosztów obecności na giełdzie jest najbardziej negatywne w grupie spółek, które pozyskały najmniej kapitału (poniżej 1 mln złotych), bardzo ważna dla postrzegania rynku jest dbałość o jakość spółek dopuszczanych na rynek NewConnect przez jego organizatora, czyli GPW w Warszawie. W szczególności w przypadku spółek, które będą przeprowadzać większe (tzn. kilkumilionowe) emisje akcji, stosunek kosztów obecności na NewConnect do pozyskanej kwoty będzie korzystniejszy, co wraz z poprawą koniunktury giełdowej powinno poprawić ocenę rynku przez emitentów.
Wiek a absencja chorobowa pracowników
Authors: Jurek Łukasz
Published: December 2021

Głównym celem artykułu jest porównanie, jak absencja chorobowa kształtuje się wśród pracowników z różnych grup wieku. Dodatkowym celem jest zweryfikowanie, czy w Polsce występuje taki sam wzór absencji chorobowej, jaki zaobserwowano w kilku innych krajach, polegający na odmiennym schemacie zachowań absencyjnych wśród młodszych i starszych pracowników. Do pomiaru absencji wykorzystane zostały trzy wskaźniki: (1) średnia częstość absencji w trakcie roku, (2) średnia długość absencji w trakcie roku, (3) średnia długość pojedynczego zwolnienia. Te wskaźniki skalkulowano dla pięcioletnich grup wieku, z uwzględnieniem dodatkowego podziału ze względu na płeć. Do obliczeń wykorzystano dane Zakładu Ubezpieczeń Społecznych na temat absencji chorobowej z tytułu choroby własnej za lata 2012–2019. Na podstawie uzyskanych wyników można stwierdzić, że pracownicy, w zależności od wieku, cechują się odmiennymi zachowaniami absencyjnymi. Chodzi tutaj jednak nie tyle o ogólny poziom absencji, ile o szczegółową jej konfigurację w zakresie poszczególnych parametrów. Przede wszystkim udało się potwierdzić wzór absencji chorobowej w odniesieniu do najmłodszych i najstarszych pracowników: najmłodsi pracownicy najczęściej korzystają ze zwolnień i są one najkrótsze, podczas gdy najstarsi pracownicy najrzadziej korzystają ze zwolnień i są one najdłuższe.

Białoruś wobec pandemii COVID-19. Praktyka i realia
Authors: Fedorowicz Krzysztof
Published: December 2021

Celem artykułu jest przedstawione podejścia władz Republiki Białoruś wobec pandemii COVID-19. Główna hipoteza badawcza przyjęta przez autora głosi, iż Białoruś od początku pandemii zdecydowała się na świadome ignorowanie pojawiającego się zagrożenia epidemiologicznego, przyjmując strategię uspokajania społeczeństwa i bagatelizowania globalnego niebezpieczeństwa. Na podstawie analizy danych dowiedziono, iż większość Białorusinów podczas pandemii COVID-19 całkowicie utraciło zaufanie do państwa i jego organów, które ich zdaniem okazały się niezdolne do podjęcia ochrony swoich obywateli przed negatywnymi skutkami (zdrowotnymi, ekonomicznymi) pandemii.

Published: December 2021

In continuation of our previous studies, we developed polymeric epigallocatechin 3-gallate (EGCG)-loaded nanoparticles (NPs) coupled with folic acid (FA), able to dually bind the human folate receptor alpha (FOLR1), and prostate-specific membrane antigen (PSMA+) in prostate cancer (PCa) model. After a preliminary computational molecular recognition of NP′ ligand binding on the FOLR1 active site, we synthesized the biocompatible block-copolymer PLGA–PEG–FA to prepare EGCG-targeted NPs (EGCG-T-NPs). The obtained NPs were characterized by various analytical techniques, and anticancer efficacy was determined by different sets of experiments in a 3D culture of PCa using PC3 and 22Rv1 cell lines. Results showed a significant reduction in spheroid size by EGCG-T-NPs, especially in PSMA+ (22Rv1) cells. The targeted NPs significantly enhanced the antiproliferative activity of EGCG against PCa cell lines, especially toward the PSMA+ cells, known to have higher FOLR1 expression. We did not observe any changes in the reactive oxygen species formation in both studied cell lines. However, significant changes in mitochondrial depolarization (15%) and polarization (18%) were recorded in response to EGCG-T-NP compared to control in 22Rv1. Similarly, EGCG-T-NP treatment also showed an increase in the number of dead apoptotic cells in 22Rv1 spheroids. Collectively, the obtained results support our hypothesis about the role of these targeted nanoprototypes in the increasing cellular uptake of EGCG payload into PCa cells, thus enhancing its antitumor efficacy.

Published: December 2021

Tensiomyography (TMG) is a noninvasive tool used to assess contractile tissue properties during an isometric muscle contraction. Owing to portability and versatility for assessing muscle parameters, TMG may be of value to the strength and conditioning (S&C) specialist. The purpose of this systematic review was to investigate the reliability of TMG measurements. PubMed, PEDro, MEDLINE, and Cochrane databases were searched up to September 2021 by 2 authors, who independently examined all titles and abstracts to determine initial eligibility. Inclusion criteria included any study assessing the reliability of TMG parameters, published in English, published in a peer-reviewed scientific journal, and included participants with no significant musculoskeletal conditions. Exclusion criteria included the following elements: TMG assessment process not clearly delineated, reliability of specific TMG parameters not clearly defined, and statistical methods for determining reliability not clearly defined. All studies underwent a quality assessment using the Modified Downs and Black checklist for assessing quality studies, and results were extracted from qualified articles. In total, 635 studies were identified, with 16 studies retained after full-text reviews. Twelve studies had poor quality, whereas 4 had fair quality. Noninvasive TMG has good to excellent absolute and interrater reliability for measuring the properties of skeletal muscles.
Extraction of Lignin from Empty Fruit Bunch Fiber via Microwave-Assisted Acid Hydrotrope Solvent
Authors: Roslan Rasidi , Yaakob Muhammad Nor Arifin , Ms Fathihah
Published: December 2021

Lignin is a sub-product from lignocellulose apart from cellulose and hemicellulose that produced from empty fruit bunch fiber (EFB). Lignin has low solubility and reactivity due to its bulky macromolecule structre. Being one of the wastes that being generated in massive amount, many alternatives has been taken to transform lignin into valuable products. To do so, many reactions are needed for the lignin to go through. In this study, lignin will be extracted from empty fruit bunch (EFB) with the aid of acid hydrotrope concentration of 30 % and microwave assisted with various extraction heating time and temperature. Characterization of lignin is done using Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric analysis (TGA), Differential Scanning Calorimetry (DSC) and Nuclear magnetic resonance (NMR) while Scanning Electron Microscopy (SEM) and X-ray Powder Diffraction (XRD) used to characterize residues. The highest percentage of lignin yield and its purity obtained are 19.47 % and 96.63 % with the reaction time and temperature of the microwave is 30 minutes and 90 °C. From Fourier Transform Infrared Spectroscopy (FTIR), a wide band at 3430.09 cm-1 and 3413.45 cm-1 are observed due to O-H stretching vibration. As for peak at 1123.17 cm-1 and 1051.26 cm-1, it correspond to syringyl and guaicyl unit in both lignin and raw EFB. As for Thermogravimetric analysis (TGA), it shows that lignin decomposes slowly compared to raw EFB due to the aromatic structure of lignin that is very stable, therefore leading to difficulty of decomposing while from Differential Scanning Calorimetry (DSC), after removing cellulose and hemicellulose, glass transition temperature (Tg) obtained from lignin DSC spectroscopy is 193.05 °C at heat flow of 1.15 mW/mg. Next, from Nuclear magnetic resonance (NMR) spectroscopy, the signals observed around 6.5 – 8.0 ppm indicate aromatic H in syringyl and guaiacyl unit only at lignin spectra while at 3.3 – 4.0 ppm, raw EFB has an intense peak compared to lignin which attribute to methoxyl group. When the residue of the lignin as well as the raw EFB powder is characterized using X-ray Powder Diffraction (XRD), the crystallinity index of the lignin with reaction time and temperature of the microwave 30 minutes and 90 °C is the highest, 69.28 %. As a conclusion, an admissible percent of lignin yield and purity is able to be obtained with addition of acid hydrotrope depending on the variables. From the spectroscopies characterization, it is proved that lignin characteristics and properties are compatible for the production of new and value added products.
The Effect of Titanium Dioxide Nanoparticles On Microhardness and SEM-EDS Analysis of Glass Ionomer Cement and Amalgomer
Authors: KAM HEPDENİZ Özge , GÜRDAL Osman
Published: December 2021

Background: The aim of this study was to examine the effect of the addition of titanium dioxide (TiO2) nanoparticles on elemental composition and micro hardness of a conventional glass-ionomer and an amalgomer.Methods: A conventional glass ionomer cement (GICs) and an amalgomer were used in this study. Seventeen samples were prepared from each material using teflon molds (8 x 2) and determined as the control group. Each material was then blended with 3 % (w/w) TiO2 nanoparticles (anatase phase, 17 nm particle size) and seventeen samples were prepared to form experimental groups. Characterization of TiO2 nanoparticles, surface morphology evaluation and elemental composition analysis of the specimens were performed by Scanning Electron Microscope (SEM) and Energy Distribution Spectrometry (SEM-EDS). Specimens were submitted to the Vickers micro hardness test for 10 seconds at a load of 100gf. Data were analyzed with Shapiro-Wilk, Kruskal-Wallis and Bonferroni post-hoc tests (p=0.05).Results: EDS mapping showed the presence of elements typical for (GICs) in the composition of the control and experimental groups and a high proportion of titanium in the composition of experimental groups. Micro hardness data showed a small insignificant increase for the experimental groups compared with the control groups (p>0.05). While the highest mean microhardness value was recorded in Amalgomer (experimental) (84.34±4.33), Ionofil (control) exhibited the lowest mean micro hardness value (58.62±6.90).Conclusion: Within the limitations of this study, it can be concluded that the addition of 3% Ti02 nanoparticles improves the surface microhardness of the tested materials, although statistically insignificant, compared to unmodified GICs and amalgomer.

Published: December 2021

Amaç: Bu çalışmanın amacı Eskişehir Osmangazi Üniversitesi Diş Hekimliği Fakültesi Ağız, Diş ve Çene Radyolojisi Anabilim Dalı Radyoloji kliniğinde çekilmiş Konik Işınlı Bilgisayarlı Tomografi (KIBT)’lerin hangi nedenlerle istendiğini belirlemektir.

Gereç-Yöntemler: Ağız, Diş ve Çene Radyolojisi arşivinden rastgele seçilen 843 KIBT’ın istem nedenleri retrospektif olarak değerlendirildi. Hasta bilgi ve yönetim sistemi üzerinde KIBT istemleri için hekimler tarafından kaydedilen Ön tanı/İstem gerekçelerine göre nedenler sınıflandırıldı ve frekansları hesaplandı.

Bulgular: Hastaların 403’ü erkek ve 440’ı kadındı. Yaş aralıkları 6-83 (ort 29.41±17.212) idi. En sık istem nedeni olan patolojiler 228 vaka ile % 27 oranındaydı. Ortodontik sebeplerle istenen 185 (% 21.9) ve gömülü dişler için istenen 169 (% 20) vaka ikinci ve üçüncü grupları oluşturuyordu. Maksillofasiyal travma nedeniyle KIBT istenen dört vaka % 0.5 oranla en alt sıradaydı.

Sonuç: KIBT’ın uygun maliyeti, düşük radyasyon dozuyla üç boyutlu olarak görüntü oluşturması gibi özellikleri sayesinde diş hekimliği pratiğinde kullanımı yaygınlaşmış olup farklı amaçlar için tercih edilmektedir. Bu avantajlarına rağmen KIBT kullanımında ALARA (As Low As Reasonably Achievable) prensipleri göz önünde bulundurulmalı ve gerekli olmayan durumlarda KIBT isteminden kaçınılmalıdır.

Background: The purpose of this study was to investigate whether there is a role of the low gonial angle on marginal bone resorption around the implants placed in the posterior mandible. Methods: This retrospective study, including 20 patients with 46 implants followed 36 months were inserted in the toothless posterior area. Patients without systemic disease were included in this study. The gonial angle was measured on a panoramic x-ray; Patients with a gonial angle of more than 1250were classified as high gonial angle, and those with less than 1200 were classified as a low gonial angle group. Mesial and distal marginal bone resorption and implant angulation with the occlusal plane were measured via Image J software (National Institutes of Health; version 1.5i, USA). Independent samples t-test was used to compare measured variables between high and low gonial angle groups. Results: The mean marginal bone resorption (MBL) was 0.27±0.16 mm for the mesial side and 0.27±0.13mm for the distal side in the LGA group. In the HGA group, MBL was 0.77±0.28mm for the mesial side and 0.71±0.27mm for the distal side. There was no statistical significance between HGA and LGA groups regarding marginal bone resorption. However, implant angulation with the occlusal plane was correlated with marginal bone resorption in the HGA group. Conclusion: The result of this study is that a low gonial angle is not directly a risk factor for marginal bone resorption around the dental implant. However, implants should be placed perpendicular to the occlusal plane as possible in the HGA group.

Peculiarities of corrosion-mechanical fracture of 09G2S pipe steel samples in the conditions of cathodic protection were investigated. It was established that depending on the level of protective potential, stress-corrosion cracking of pipe steel of a ferrite-pearlite class 09G2S can occur by different mechanisms. The range of protective potentials was determined, at which the anodic dissolution and hydrogen embrittlement occur simultaneously during the fracture of steel, namely from -0.85 V to -1.0 V. The existence of the above mechanisms is confirmed by the change in the strength and viscosity properties of the steel and the morphology of the fractures. For steels of other manufacturing technology and grades, these potential areas may differ.
Sichert Taiwans Chipindustrie den Frieden?
Authors: Kuhn Britta
Published: December 2021

Die geopolitischen Spannungen um Taiwan haben 2021 zugenommen. Ihre Ursachen reichen historisch weit zurück. Jahrzehntelang schützte ein komplizierter Kompromiss zwischen Washington, Peking und Taipeh vor Krieg. Aber Taiwans Bevölkerung hat sich von der Volksrepublik China entfremdet. Kann die Insel dank ihrer überlegenen Chiptechnologie eigenständig bleiben? Ökonomisch läge der politische Status-quo-Erhalt weiterhin im Interesse aller Akteure.
Business Transformation Controlling jenseits der Digitalisierung
Authors: Baumöl Ulrike
Published: December 2021

Transformation in allen denkbaren Ausprägungen von klassisch bis digital ist in aller Munde. Ob es als „Schreckgespenst” oder als die Chance für ein Unternehmen wahrgenommen wird, hängt oftmals davon ab, wie viel Vertrauen in die Fähigkeiten der Organisation gesetzt werden und wie ausgeprägt der Optimismus ist. Ohne ein wirksames Steuerungsinstrumentarium ist aber auch das größte Vertrauen und der unerschütterliche Optimismus als Basis nicht genug. Aus diesem Grund wird nachfolgend ein Business Transformation Controlling konzipiert, das die Anforderung an eine ganzheitlich gesteuerte Transformation aufnimmt und dabei unabhängig von einem spezifischen Kontext, wie z. B. der Digitalisierung, aufgesetzt werden kann – der Kontext verändert letztlich „nur“ die Ausprägung.

Filmförderung in Deutschland – weiterhin ein Erfolgsmodell?
Authors: Graeser Stefan
Published: December 2021

Die Filmförderung in Deutschland ist Gegenstand kontroverser Diskussionen. Sie versucht eine Position zwischen Kunst- und Wirtschaftsförderung einzunehmen. Durch eine medienökonomische Perspektive kann das Wirken der Filmförderung in beide Richtungen untersucht werden. Die mikroökonomische Theorie der Wirtschaftswissenschaften hinterfragt staatliche Förderung kritisch. Diese Kritik wäre zu entschärfen, wenn Anreiz- anstelle von Steuerungsstrukturen treten. Die Abkehr von der bisherigen „Spitzenförderungspolitik“ würde zudem Freiräume für innovative Formate und Inhalte schaffen, was aus künstlerischer Sicht wünschenswert ist. Vor dem Hintergrund eines sich wandelnden Mediennutzungsverhaltens, und dem neuen Aufmerksamkeitswettbewerb mit Plattformbetreibern, erscheinen beide Ansatzpunkte besonders sinnvoll.

The Tarat aquifer provides drinking water for the population of the city of Arlit and also provides water to industries. The exploitation of this aquifer has considerably increased in recent years. The main objective of this study is to contribute to a better understanding of the functioning of the Tarat aquifer. Thus, a methodological approach focusing mainly on the piezometric study and the analysis of evolution and estimation of the volumes of water pumped, since its development from 1969 to 2012, which has resulted in highlighting not only a general decline in the level of the Tarat aquifer, but also the piezometer level (Arli_182), reacts strongly to the solicitations of the aquifer. On this same piezometer, the water table was lowered by 30 m from 1980 to 2006 (26 years), so a drawdown of 0.86 /year.

The Rietveld refinement method has taken high relevance since its creation. Nowadays, it is an useful tool in many fields of industry, materials science, and technology. For these reasons, it becomes a need for scientists and engineers whom pretend to use it for proper analysis of their materials. However, the initiation in the method can be slow, taking into account the accelerated rhythm of the research and economic demands. Thus, this work is an intend to fulfill this hole, providing the basic foundations and methodology of the Rietveld refinement in a brief way, this along with the results of its application in superconducting samples of Yttrium Barium Copper Oxide and magnesium diboride, and functional magnetic nanoadsorbents of maghemite and a multiphasic composite (iron oxide, hydroxyapatite and secondary phases). In the process, an in-detail protocol was designed and provided. It was concluded that the samples were successfully refined and that this work represents a fast introduction to the Rietveld method for which beginners can obtain good results while making correct interpretations ofthe whole refinement process.
