Navigation with minimal occupation volume for teleoperated snake-like surgical robots: MOVE
Authors: Berthet-Rayne Pierre , Yang Guang-Zhong 
Published: June 2023

Master-Slave control is a common mode of operation for surgical robots as it ensures that surgeons are always in control and responsible for the procedure. Most teleoperated surgical systems use low degree-of-freedom (DOF) instruments, thus facilitating direct mapping of manipulator position to the instrument pose and tip location (tip-to-tip mapping). However, with the introduction of continuum and snake-like robots with much higher DOF supported by their inherent redundant architecture for navigating through curved anatomical pathways, there is a need for developing effective kinematic methods that can actuate all the joints in a controlled fashion. This paper introduces the concept of navigation with Minimal Occupation VolumE (MOVE), a teleoperation method that extends the concept of follow-the-leader navigation. It defines the path taken by the head while using all the available space surrounding the robot constrained by individual joint limits. The method was developed for the i2Snake robot and validated with detailed simulation and control experiments. The results validate key performance indices such as path following, body weights, path weights, fault tolerance and conservative motion. The MOVE solver can run in real-time on a standard computer at frequencies greater than 1 kHz.

Published: June 2023

IntroductionAcrylonitrile-butadiene-styrene copolymer (ABS) and high impact polystyrene (HIPS) are plastics typically found in waste electrical and electronic equipment (WEEE or e-waste). As such, recycling is a beneficial method for reintroducing polymeric materials from electrical and electronic equipment to the same production cycle. This study aimed to investigate mechanical recycling of ABS and HIPS from WEEE reprocessed six times, totaling 24 cycles.MethodsReprocessing was performed by extrusion and test specimens were obtained by injection. The technical aspects assessed before and after reprocessing were mechanical properties (tensile, flexural and impact strength), thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FTIR) and melt flow index (MFI), compared with those of reprocessed virgin polymeric materials. The environmental aspect was evaluated by monitoring energy consumption and solid waste generation during each reprocessing cycle.ResultsAverage energy consumption per extrusion and injection cycle was 0.7 and 2.0 kW/kg, respectively. There was a 30% increase in MFI from the first to sixth reprocessing cycle for virgin HIPS (5.5 g/10 min in 200°C and 5 kg), the largest among the polymers. The values for virgin ABS (6.0 g/10 min in 200°C and 5 kg) and ABS and HIPS from WEE increased by 11–15% from the first to sixth cycle. Impact strength was affected from the second reprocessing cycle onwards for ABS e-waste (14% decrease) and in the fifth cycle (16% decrease) for HIPS e-waste.DiscussionThe thermal, tensile and flexural properties of the virgin and post-consumer materials remained almost unchanged as the number of reprocessing cycles increased, indicating that these materials have the potential and properties for reintroduction into the same production cycle.

IntroductionArthroplasty is the final treatment option for maintaining mobility and quality of life in many primary degenerative and (post-) traumatic joint diseases. Identification of research output and potential deficits for specific subspecialties may be an important measure to achieve long-term improvement of patient care in this field.MethodsUsing specific search terms and Boolean operators, all studies published since 1945 to the subgroups of arthroplasty listed in the Web of Science Core Collection were included. All identified publications were analysed according to bibliometric standards, and comparative conclusions were drawn regarding the scientific merit of each subgroup.ResultsMost publications investigated the subgroups of septic surgery and materials followed by approach, navigation, aseptic loosening, robotic and enhanced recovery after surgery (ERAS). In the last 5 years, research in the fields of robotic and ERAS achieved the highest relative increase in publications In contrast, research on aseptic loosening has continued to lose interest over the last 5 years. Publications on robotics and materials received the most funding on average while those on aseptic loosening received the least. Most publications originated from USA, Germany, and England, except for research on ERAS in which Denmark stood out. Relatively, publications on aseptic loosening received the most citations, whereas the absolute scientific interest was highest for the topic infection.DiscussionIn this bibliometric subgroup analysis, the primary scientific outputs focused on septic complications and materials research in the field of arthroplasty. With decreasing publication output and the least financial support, intensification of research on aseptic loosening is urgently recommended.

Cordycepin, also known as 3′-deoxyadenosine, is a major active ingredient of Cordyceps militaris with diverse pharmacological effects. Due to its limited supply, many attempts have been conducted to enhance the cordycepin content. As part of this study, eight medicinal plants were supplemented with cultivation substrates of Cordyceps to increase the cordycepin content. Cordyceps cultivated on brown rice supplemented with Mori Folium, Curcumae Rhizoma, Saururi Herba, and Angelicae Gigantis Radix exhibited increased cordycepin content compared to a brown rice control. Among them, the addition of 25% Mori Folium increased the cordycepin content up to 4 times. Adenosine deaminase (ADA) modulates the deamination of adenosine and deoxyadenosine, and the inhibitors have therapeutic potential with anti-proliferative and anti-inflammatory properties. As ADA is also known to be involved in converting cordycepin to 3′-deoxyinosine, the inhibitory activity of medicinal plants on ADA was measured by spectrophotometric analysis using cordycepin as a substrate. As expected, Mori Folium, Curcumae Rhizoma, Saururi Herba, and Angelicae Gigas Radix strongly inhibited ADA activity. Molecular docking analysis also showed the correlation between ADA and the major components of these medicinal plants. Conclusively, our research suggests a new strategy of using medicinal plants to enhance cordycepin production in C. militaris.

This study aimed to investigate the effects of different relative humidities (%) on the microbial safety, antioxidant activity, ascorbic acid, fucoxanthin, and tocopherol contents of Undaria pinnatifida sporophyll powder (UPSP) stored for 4 weeks. The caking phenomenon did not occur in the 11–53% relative humidity conditions, but it did in the 69%, 81%, and 93% relative humidity conditions with caking index values of 88.30%, 99.75%, and 99.98%, respectively. The aerobic bacterial contents increased drastically in samples stored at 69–93% relative humidity. Ascorbic acid was unstable at high relative humidity, but fucoxanthin and tocopherol were more unstable at low relative humidity. Therefore, it was most stable at intermediate relative humidity. The 69% relative humidity sample had higher DPPH (12.57 g BHAE/kg), ABTS (4.87 g AAE/kg), and FRAP (4.60 g Fe (II)/kg) than the other samples. This study could be helpful for the storage and transport of UPSP under optimum relative humidity conditions, which can significantly prevent quality losses.

Published: June 2023

Нейрофиброма – это доброкачественная опухоль из элементов эндопериневрия, шванновских клеток, связана с оболочками периферических нервов. Нейрогенные опухоли в пределах лор-органов встречаются крайне редко. Данных о распространенности доброкачественных нейрогенных образований полости носа у детей в доступных информационных источниках найти не удалось. Редкость встречаемости данного заболевания подчеркивает необходимость раннего использования патогистологического исследования с последующим хирургическим лечением. В данной статье рассматривается случай врожденной нейрофибромы полости носа у ребенка женского пола в возрасте 1 года 6 месяцев на момент хирургического лечения. Для диагностики использованы эндоскопическое исследование полости носа, компьютерная томография (КТ), патогистологическое исследование. Учитывая редкость встречаемости данного заболевания, мы полагаем, что описание данного клинического случая позволит врачам-оториноларингологам лучше ориентироваться в диагностике новообразований полости носа у детей.
Neurofibroma is a benign tumor composed of elements of endoperineurium, Schwann cells, and associated with peripheral nerve sheaths. Neurogenic tumors within the ENT organs are extremely rare. No data on the prevalence of benign neurogenic nasal cavity neoplasms in children have been found in available informational sources. This article describes a case of congenital neurofibroma of the nasal cavity in a female child aged 1 year 6 months at the time of surgical treatment. Endoscopic examination of the nasal cavity, computed tomography (CT), and pathohistological examination were used for diagnosing. The rarity of this disease emphasizes the need for early use of pathohistological examination followed by surgical treatment. Given the rarity of this disease, we believe that the description of this clinical case will allow otorhinolaryngologists better guidance in the diagnosis of nasal cavity neoplasms in children.

O wartości rodzicielstwa w opiniach studentów
Authors: Matyjas Bożena 
Published: June 2023

CEL NAUKOWY: Celem artykułu jest przedstawienie opinii studentów dotyczących wartości rodzicielstwa w ich życiu.
PROBLEMY I METODY BADAWCZE: Problem badawczy sformułowany został w postaci następującego pytania: jaką wartość dla badanych studentów ma rodzicielstwo? Wykorzystana została metoda sondażu diagnostycznego (technika ankiety) oraz metoda analizy i syntezy literatury przedmiotu.
PROCES WYWODU: W artykule pokazane zostały, w świetle otrzymanych danych empirycznych, takie wymiary rodzicielstwa jak: jego wartość wyrażona poprzez deklarowany poziom, opinie studentów dotyczące zadań i funkcji realizowanych przez rodzinę, współczesne problemy i trudności w rodzicielstwie, poglądy/opinie na temat rodzicielstwa, a także cechy, jakie powinien posiadać rodzic.
WYNIKI ANALIZY NAUKOWEJ: Wartość rodzicielstwa w życiu badanych studentów analizowana była w odniesieniu do takich zmiennych jak: płeć, wiek, miejsce zamieszkania oraz typ i struktura rodziny pochodzenia. Badani wskazują na średni poziom rodzicielstwa, łączenie go z wysokimi kosztami utrzymania, a także rezygnacją z kariery zawodowej. Zwrócili ponadto uwagę na zjawisko samotnego rodzicielstwa (duży odsetek rozwodów), a także odpowiedzialność jako bardzo ważnącechę rodzica/rodzicielstwa.
WNIOSKI, INNOWACJE, REKOMENDACJE: Z dokonanych analiz wynika, że badana grupa studentów wyraża pozytywne opinie o rodzicielstwie, które jest dla nich wartością (średni poziom). Ich postrzeganie rodzicielstwa jest dojrzałe – bycie mamą, bycie tatą to dla nich nie tymczasowe pragnienie, lecz konsekwencja i podstawa do zbudowania prawidłowo funkcjonującej rodziny. Wiedza dotycząca rodzicielstwa powinna być włączona w system edukacji młodych ludzi, począwszy od szkoły podstawowej, poprzez średnią i wyższą (przedmiot „społeczny” dla wszystkich kierunków studiów).
Reduction of dislocation density in α-Ga2O3 epilayers via rapid growth at low temperatures by halide vapor phase epitaxy
Authors: Oshima Yuichi , Ando Hiroyuki , Shinohe Takashi 
Published: June 2023

Abstract
We demonstrate that the dislocation density in α-Ga2O3 epilayers is markedly reduced via rapid growth at low temperatures by halide vapor-phase epitaxy. An α-Ga2O3 epilayer grown on (0001) sapphire at a high growth rate of 34 μm h−1 and a low temperature of 463 °C exhibited a dislocation density of 4 × 108 cm−2, which was approximately 1/100 of that in a conventional film. It is likely that the three-dimensional surface morphology developed during the growth enhanced the bending of the dislocations to increase the probability of pair annihilation. The combination of this technique with thick film growth and epitaxial lateral overgrowth resulted in a further low dislocation density of 1.1 × 107 cm−2.

“PEMBACAAN PENONTON TERHADAP ISU PRIMITIVE DALAM PROGRAM ACARA REALITY SHOW PRIMITIVE RUNAWAY EPISODE NEGERI DIATAS AWAN SUKU SAMBORI”
Authors: Putra Sandi Justitia , Rahmat L. Ahmad , I Made Putra Suryantara  
Published: June 2023

Primitive Runaway (PR) adalah program yang menampilkan artis bersama sahabatnya untuk mempelajari adat, budaya serta kebiasaan sebuah sebuah suku, salah satunya episode Negeri diatas Awan Suku Sambori Bima. Kontroversi penonton berawal dari tafsir diri mereka terhadap teks yang dipoduksi oleh PR. Melalui acara ini penonton yang bukan berasal dari Bima akan memiliki persepsi bahwa masyarakat bima adalah masyarakat yang primitif dan terbelakang. Perbedaan pandangan penonton dapat dimengerti karena penonton merupakan pencipta makna. Penelitian ini menggunakan pendekatan kualitatif melalui pengumpulan data berupa pendeskripsian mengenai level-level analisis Reality Show PR mulai dari dialog serta adengan dari setiap scene. Metode yang digunakan adalah etnografi media yang digunakan untuk menyelidiki media dan melakukan eksplorasi terhadap entitas (users) saat menonton produk media tersebut. Kesimpulan penelitian ini yakni Adat Istiadat masyarakat Sambori telah membawa ragam makna yang kemudian oleh para penonton di decoding secara berbeda. Hasil analisa informan dengan latar belakang budaya yang berbeda menunjukan posisi dan identitas yang berbeda pula. Kehadiran penonton adalah nyawa bagi setiap tontonan. Pengalaman hidup penonton memberikan pengaruh dalam interaksinya dengan teks media. Penonton menginterpretasikan teks media sesuai dengan keadaan sosial dan kebudayaannya. Latar belakang penonton yang berbeda sehingga apa yang dimaknai dari acara ini pun akan dimaknai secara berbeda pula.
