Prosthetic management of acquired dentate maxillectomy defects: A clinical case series
Authors: Sharma Vineet , Paliwal Jyoti , Gurjar Balwant Singh , Meena Kamal Kumar 
Published: July 2022

AbstractAcquired maxillectomy defects produce hypernasal speech, food, and liquid regurgitation into the nasal cavity, impaired deglutition and mastication, and cosmetic deformity. Furthermore, patients with acquired maxillary defects face psychosocial stigma, which has a negative impact on their quality of life. Prosthetic rehabilitation of such defects is required for stomatognathic system restoration and oroantral communication obturation. This case series discusses the fabrication of surgical, interim, and definitive obturator prostheses to restore the acquired dentate maxillectomy defects of three cancer patients. All patients had their treatment in the prosthodontics department of the RUHS College of Dental Sciences. The surgical obturator prosthesis was made before surgery, whereas the interim and definitive obturators were made one month and six months after surgery, respectively. The surgical obturator formed a shield between the surgical pack and the oral cavity. After the surgical obturator and packing were removed, an interim obturator was inserted for three to six months to allow the surgical site to heal. After the surgical site had healed, the fabrication of the definitive obturator began. Prosthetic rehabilitation with obturator prostheses sealed the acquired tissue defects of the palate and restored swallowing, speaking, chewing capacity, and cosmetic value, as well as significantly improved the quality of life of these patients.

Abstract

Introduction: At the time of diagnosis, most patients with lung cancer are in an inoperable stage, with distant metastases. Most often, these patients have metastases to the brain, adrenal glands, liver, or bones. This article presents the case of a patient with non-small-cell lung cancer (NSCLC) metastases in the abdominal wall.

Case presentation: A 67-year-old patient came to our service reporting the existence of a tumor 5 cm in diameter, located at the level of the abdominal wall, without other clinical symptoms. Surgical excision of the tumor was performed. The postoperative evolution was favorable, with the patient discharged on the third postoperative day. Histological examination of the resected specimen revealed metastasis of squamous cell carcinoma of the lung.

Conclusions: The appearance of a tumor in the abdominal wall of patients with NSCLC may raise the suspicion of metastasis at this level.

AbstractObjective: To compare and evaluate the cephalometric hard and soft tissue changes of mandible after orthodontic treatment with and without extraction of four first premolar.Methodology:60 individuals with Class I skeletal pattern were selected as per inclusion criteria. They were divided into two groups: 30 in the extraction group and 30 in the non-extraction group. Each group consists of 15 males and 15 females. Pre-treatment and post-treatment lateral cephalograms of the selected subjects were obtained, analysed and compared to assess the changes might have occurred. Descriptive statistics of the explanatory and outcome variables were calculated by mean and standard deviation for quantitative variables. Paired t test was applied to check the statistical difference of pre-treatment and post-treatment cephalometric parameters within the group (Extraction and non-extraction). Unpaired t test was used to check the statistical difference between extraction and non-extraction groups. The level of significance is set at 5%.Results: B point moved backward with lower incisor retraction. N-A-Pog shows a statistically significant decrease in the extraction group (P=0.003). B-NP shows a statistically significant decrease in extraction group (P=0.001). N- A’-Pog’ shows a statistically significant increase in non-extraction group (P=0.046). Soft tissue thickness in chin increases in extraction group and decreases in non-extraction group.Conclusion: The results indicate that premolar extraction will have a flattening effect on the midface. With proper diagnosis and treatment planning, premolar extractions have high potential to improve the facial profile.
Supporting Industrial Implementation of R&D Results with Commercialisation Models
Authors: Poteralska Beata , Walasik Marzena 
Published: July 2022

Abstract
The paper aims to present commercialisation models for advanced technologies and services which can be applied in an R&D organisation. Against the background of the literature review on theoretical and practically verified commercialisation models, and marketing strategies and tools, the authors propose an original model, 7MWwBP, composed of several hybrid submodels. The model is intended to support commercialisation processes carried out at R&D organisations. The model is based on the input criteria (the type of innovation and the character of the innovation related to the market demand scale), and it indicates possible commercialisation paths (sale, licence, provision of a service, or a spin-off) and sets of dedicated marketing tools (BTL). The advantage of the model is that an R&D result (innovation) is its focal point, and the whole commercialisation process depends on it. The model aims to mitigate an empirical and research gap as regards commercialisation models suitable for R&D organisations. Furthermore, the model is distinguished by a holistic approach, which is not common for the commercialisation models described in the literature, as they do not comprehensively consider the relationship between the models and the type and character of a technological solution, commercialisation path, and the marketing tools used for commercialisation of R&D results. All the listed aspects are considered and included in the 7MWwBP model, which makes it suitable for the commercialisation of R&D results originating from research organisations, as presented in and substantiated by the example of an actual commercialisation process concerning R&D results in the field of optomechatronics.

Published: July 2022

Abstract
The growing competition for customers requires constant improvement of service quality, continuously raising the importance of this matter and the significance of the entire service sector. Essentially, service quality concerns not only the private but also the public sector. Service quality in the public sector has already been widely discussed in the literature. Among research themes in the frame of public service quality, the healthcare sector attracts particular attention from researchers. Therefore, this study aimed to identify research topics on the public service quality and healthcare quality discussed in the SCOPUS database from 2012 to 2022. A bibliometric technique and the VOSviewer software were used to analyse over 25 000 articles on public service and healthcare service published over ten years. As a result, a total of ten research themes were set up, five in the healthcare sector and five in the public sector, which were linked using keywords and presented on maps. The identified research themes demonstrate the most popular research directions and indicate research gaps related to the subject.
Implementasi Algoritma Greedy dan Djikstra untuk Efektifitas Rute Pariwisata Populer di Borobudur
Authors: Rahmawati Eka , Agustina Candra 
Published: July 2022

New tourist attractions in the Borobudur region always bring domestic and foreign tourists to visit. Besides visit the Borobudur Temple, now, the tourists can visit the other popular tourist attractions near the main destination. For example, in 2019, a new tourist attraction was created, it called Mata Langit. Many tourists will include all the interest object on the visit list. The more destinations that will be visited will increase the allocation of time to travel. Tourists must be careful in determining the route. The effective route is very important to manage the time. In the field of computer technology, several algorithms can help to determine the shortest route. Among them are the Greedy algorithm and Djikstra's algorithm. Both algorithms have different principles in processing data. Therefore to get the best results, it is necessary to compare the 2 algorithms. The first time, determined the 5 most popular attractions in Borobudur based on the number of visitors in the last three months. Then the data is processed using Greedy and Djikstra's algorithm. The winner is determined based on the shortest time owned by each route produced. The results obtained show that the Greedy algorithm is more effective in calculating the shortest route to visit popular tours in Borobudur
Transradial versus transfemoral arterial access in DEB-TACE for hepatocellular carcinoma
Authors: Ghosh Abheek , Gupta Vikash , Al Khalifah Abdullah , Akhter Nabeel Mohsin 
Published: July 2022

Objectives
Transradial access has become increasingly popular in body interventional procedures but has not been ubiquitously adapted. This retrospective study compares the efficacy of this approach versus transfemoral access in hepatocellular carcinoma (HCC) patients who underwent drug-eluting bead transarterial chemoembolization (DEB-TACE).

Materials and Methods
A total of 130 HCC patients underwent 146 DEB-TACE procedures within our institution from June 2015 to May 2020. About 90 and 56 procedures were logged for the transradial and transfemoral cohorts, respectively. Peak skin dose, fluoroscopy time, administered contrast volume, total procedure time, and equipment cost data for each procedure were reviewed to evaluate for statistical differences between the two groups.

Results
All 146 cases were technically successful without major complications or access failures in either group. No statistical differences were present between the two access groups in regards to peak skin dose or fluoroscopy time. Transradial access recorded a significantly higher contrast volume (P < 0.05), and a significantly longer procedural time than transfemoral access (P < 0.01). However, transradial access also displayed a significantly lower procedural equipment cost (P < 0.01) between the two groups.

Conclusion
Transradial DEB-TACE has similar trends to transfemoral DEB-TACE in several pertinent radiation parameters and is also significantly more cost-efficacious. The results of this investigation suggest the consideration of transradial access whenever viable as an alternative to transfemoral access in the DEB-TACE treatment of HCC patients.

Published: July 2022

Background:
Ceftriaxone is a commonly used antibiotic in a wide range of local and systemic infections. Encephalopathy is a rare complication of ceftriaxone, often seen in older adults and those with renal insufficiency.

Case Description:
A 73-year-old lady with prior history of hypertension and dyslipidemia presented with the complaints of slurred speech, gait imbalance, nocturnal vomiting, and progressively worsening headache. A magnetic resonance imaging of the brain revealed two intracerebral lesions involving the right frontal and temporal lobes, suggestive of multicentric glioma. She underwent craniotomy and excision of these lesions. The biopsy was reported as intra-axial tumors with features suggestive of the WHO Grade IV glioma. Postoperatively, she did not wake up. An electroencephalogram demonstrated triphasic waves suggestive of encephalopathy. The probable diagnosis of ceftriaxone-induced encephalopathy was made after ruling out other causes of delayed awakening after surgery. Ceftriaxone was discontinued and the patient improved within 2 days of withdrawal of ceftriaxone.

Conclusion:
Drug-induced encephalopathy should be considered in the differential diagnosis of patients with delayed awakening after surgery. Discontinuation of the drug leads to the recovery of these patients.

Published: July 2022

В статье рассмотрен процесс извлечения ванадиевых соединений из кислых растворов, полученных в ходе промышленной переработки ванадийсодержащего сырья по содовой технологии с недостатком натрия от стехиометрии, с использованием аммонийной соли – нитрата аммония. В результате проведения данного процесса образуется ванадат аммония, из которого возможно получать чистый пентаоксид диванадия путем высокотемпературного прокаливания. Проведены эксперименты с предварительной очисткой раствора от примесных соединений и без очистки раствора. Данное исследование направлено на определение оптимальных параметров процесса извлечения ванадия из ванадийсодержащего раствора нитратом аммония.
The paper considers the process of vanadium compounds extraction from acid solutions obtained during industrial vanadium-containing slags processing using ammonium salt - ammonium nitrate. This process produces ammonium vanadate which could be roasted at high temperatures to obtain pure diwanadium. Experiments were carried out with and without pre-treatment of the solution from impurity compounds. This study determined the optimum parameters of the process of vanadium extraction from vanadium-containing solution by ammonium nitrate.
Entretien avec Francis Édeline

Né en 1930, de formation scientifique (biochimiste), Francis Édeline est membre fondateur du Groupe μ, professeur honoraire à l’Université de Liège, auteur et coauteur de très nombreux essais en sémiotique, sémiotique visuelle et en rhétorique générale et de la poésie. Cet entretien par voie épistolaire, rédigé entre le printemps et l’été 2021, puis revu avant publication, donne un aperçu de son parcours, de ses multiples intérêts, de certaines questions de fond qui animent son travail sémiotique et scientifique, mais aussi de son activité dans la création artistique. Il y réfléchit notamment à la sémiotique de l’art, aux relations de celle-ci avec d’autres champs d’étude (sémiotique visuelle et de l’image, psychologie de la perception, neurosciences), aux résultats et aux défis à relever pour mieux saisir comment une sémiotique de l’art peut s’intégrer dans une théorie de plus vaste étendue.
Wunderbare Kombinationen. Figurabilité des guerres du Golfe chez Gerhard Richter et Werner Herzog
Authors: Mengoni Angela 
Published: July 2022

La première et la deuxième guerre du Golfe font partie des interventions militaires « préventives » typiques de l’État d’exception, qui trouvent leur légitimité dans la perception partagée d’une menace et d’un risque imminents. À dix ans d’intervalle, Gerhard Richter et Werner Herzog se confrontent à ces événements. Le premier avec le livre War Cut (2003), dans lequel il assemble des extraits de journaux sur la guerre et des détails d’une de ses peintures abstraites ; le second avec le film Leçons de ténèbres (Lektionen in Finsternis 1992), dans lequel il explore le paysage du Koweït dévasté par des puits de pétrole en feu, mais accompagne les images d’un texte apocalyptique qui ne fait aucune référence explicite au conflit. L’article discute et réfute les accusations d’« esthétisation de la guerre » portées par certains critiques à l’encontre de ces œuvres et montre comment elles témoignent au contraire d’aspects spécifiques de ces conflits. En particulier, à travers une focalisation sur l’émergence de la figurativité ou sur son érosion, elles réfléchissent aux stratégies médiatiques de production du risque, ou à l’impact traumatique du conflit sur la population civile.
Numerical solution of an elliptic problem with several interfaces
Authors: Шапеев В.П. , Брындин Л.С. , Беляев В.А. 
Published: July 2022

Разработан алгоритм высокоточного численного решения эллиптического уравнения второго порядка при наличии в области нескольких интерфейсов, в том числе пересекающихся и невыпуклых. Для аппроксимации задачи в окрестности интерфейсов используются нерегулярные ячейки (н-ячейки), отсекаемые ими от регулярных ячеек прямоугольной сетки, и законтурные части этих ячеек. Для построения приближенного решения предложено: 1) выписывать дополнительные условия согласования в н-ячейках на интерфейсах, увеличивая количество согласуемых ячеек вблизи интерфейсов; 2) уменьшать общую часть интерфейса, заключенную в соседних ячейках и используемую для записи условий. Для решения краевой задачи Дирихле реализован hp-вариант метода коллокации и наименьших квадратов (hp-МКНК) в сочетании с современными алгоритмами ускорения итерационного процесса: предобуславливание; распараллеливание с помощью OpenMP; ускорение, основанное на подпространствах Крылова; многосеточный алгоритм. При решении различных тестовых задач исследованы сходимость hp-МКНК и обусловленность возникающих переопределенных систем линейных алгебраических уравнений (СЛАУ). Проведено сравнение результатов, полученных МКНК, с результатами других авторов, использовавших метод MIB (англ. matched interface and boundary).
An algorithm of the high-accuracy numerical solution of the second order elliptic equation with several interfaces including intersecting and non-convex ones is developed. To approximate the interface problem in the neighbourhood of the discontinuity lines irregular cells (i-cells) which are cut off by the discontinuity lines from the regular cells of the rectangular grid and the “outsidethe-contour” parts of the cells are used. To construct an approximate solution, it is proposed: 1) to write out the additionally matching conditions in i-cells on interfaces increasing the number of matching cells; 2) to reduce the common part of the discontinuity line enclosed between neighboring cells and used for setting conditions. To solve the Dirichlet boundary value problem the hp-version of the least-squares collocation method (hp-LSCM) is implemented in combination with modern algorithms for accelerating the iterative process: preconditioning, parallelization of the computational program using OpenMP, Krylov subspaces; multigrid method. The convergence of the hp-LSCM and the conditionality of the arising overdetermined systems of linear algebraic equations (SLAE) are investigated in solving various test problems. The results obtained by the LSCM and other authors using the method MIB (matched interface and boundary) are compared.
IPO Underpricing a wysokość ceny emisyjnej na rynku NewConnect
Authors: Frydrych Sylwia 
Published: July 2022

Przedmiot badań: W artykule podjęto tematykę spółek debiutujących na zorganizowanym rynku akcji, prowadzonym przez Giełdę Papierów Wartościowych S.A. poza rynkiem regulowanym w formie alternatywnego systemu obrotu, zwracając uwagę na kształtowanie się ceny emisyjnej akcji spółki w porównaniu z jej ceną na koniec pierwszego dnia notowania.
Cel badawczy: Celem artykułu jest analiza zjawiska IPO Underpricing na rynku NewConnect w latach 2007–2020 w zależności od wysokości ceny emisyjnej akcji w dniu debiutu. Sprawdzono także, ile wynosiła średnia zmiana ceny papieru wartościowego oraz liczba spółek. Ponadto zwrócono uwagę na zmiany cen w dniu debiutu na NewConnect po wprowadzeniu regulacji dotyczących podwyższenia wartości nominalnej akcji do 0,10 zł.
Metoda badawcza: W opracowaniu dokonano przeglądu literatury tematu, wykorzystano metodę dedukcji oraz posłużono się metodą obserwacji. Przeprowadzono analizę danych źródłowych oraz aktów prawnych dotyczących NewConnect. Zamieszczono statystyki opisowe dotyczące zmiany ceny w dniu debiutu spółki na NewConnect.
Wyniki: Na podstawie analizy 620 spółek dopuszczonych do obrotu na rynku NewConnect wykazano, iż akcje 60,22% spółek posiadały wyższą cenę na koniec pierwszego dnia notowań w stosunku do ceny emisyjnej. Prym wiodą debiuty spółek groszowych, tj. o cenie emisyjnej poniżej 1 zł. Przy czym, przed 1 kwietniem 2010 r. średni wzrost ceny w dniu debiutu wynosił 176,06%. Po wprowadzeniu regulacji dotyczących podwyższenia wartości nominalnej akcji do 0,10 zł zmniejszyła się zmienność ceny w dniu debiutu wśród spółek groszowych, co spowodowało ograniczenie ryzyka inwestycyjnego na rynku NewConnect. Biorąc pod uwagę liczbę spółek debiutujących na NewConnect, przeważają podmioty, które wyemitowały papiery wartościowe posiadające cenę emisyjną powyżej 5 zł, przy czym średni wzrost ceny dla tych walorów był najniższy i kształtował się średnio na poziomie 32,83%.

Authors: Mikita Małgorzata 
Published: July 2022

Przedmiot badań: Przedmiotem badań jest rynek papierów dłużnych emitowanych przez przedsiębiorstwa niefinansowe w Polsce, Francji, Włoszech, Czechach, Słowacji i na Węgrzech.
Cel badawczy: Celem pracy jest ocena rozwoju rynku papierów dłużnych emitowanych przez przedsiębiorstwa niefinansowe w Polsce na tle rynków w wybranych krajach UE. Podstawowa teza pracy brzmi – rynek papierów dłużnych emitowanych przez przedsiębiorstwa niefinansowe w Polsce jest rynkiem słabo rozwiniętym.
Metoda badawcza: Praca opiera się na analizie danych statystycznych obrazujących rozwój rynku papierów dłużnych emitowanych przez przedsiębiorstwa niefinansowe w Polsce i wybranych krajach UE. Podstawowym źródłem danych były statystyki w zakresie instrumentów dłużnych prezentowane przez Bank Rozrachunków Międzynarodowych. W analizie skupiono się na wielkości i dynamice zmian zadłużenia z tytułu papierów dłużnych emitowanych przez przedsiębiorstwa niefinansowe w okresie 2010–2019 oraz dynamice zmian wielkości emisji zagranicznych. Dodatkowo, w celu przeprowadzenia analizy porównawczej stopnia rozwoju rynku papierów dłużnych emitowanych przez przedsiębiorstwa niefinansowe w omawianych krajach, odniesiono wartość zadłużenia z tytułu papierów dłużnych emitowanych przez przedsiębiorstwa niefinansowe do PKB w poszczególnych krajach, wyliczając wskaźnik zadłużenia do PKB.
Wyniki: Analiza rynku papierów dłużnych emitowanych przez przedsiębiorstwa niefinansowe w Polsce na tle rynków papierów dłużnych emitowanych przez przedsiębiorstwa niefinansowe w Hiszpanii, Francji, Włoszech, Słowacji, Czechach i na Węgrzech pozwala stwierdzić, iż poziom rozwoju tego rynku w Polsce odbiega od poziomu rozwoju rynku francuskiego, hiszpańskiego, włoskiego czy też czeskiego. Stopień rozwoju rynku w Polsce można porównać do stopnia rozwoju rynku słowackiego. Przeprowadzona analiza pozwala dodatkowo stwierdzić, że przedsiębiorstwa niefinansowe w Polsce nie są zainteresowane dokonywaniem emisji papierów dłużnych na rynki zagraniczne.
