Published: October 2022

Aims

The aim of this study was to develop and evaluate machine-learning-based computerized adaptive tests (CATs) for the Oxford Hip Score (OHS), Oxford Knee Score (OKS), Oxford Shoulder Score (OSS), and the Oxford Elbow Score (OES) and its subscales.

Methods

We developed CAT algorithms for the OHS, OKS, OSS, overall OES, and each of the OES subscales, using responses to the full-length questionnaires and a machine-learning technique called regression tree learning. The algorithms were evaluated through a series of simulation studies, in which they aimed to predict respondents’ full-length questionnaire scores from only a selection of their item responses. In each case, the total number of items used by the CAT algorithm was recorded and CAT scores were compared to full-length questionnaire scores by mean, SD, score distribution plots, Pearson’s correlation coefficient, intraclass correlation (ICC), and the Bland-Altman method. Differences between CAT scores and full-length questionnaire scores were contextualized through comparison to the instruments’ minimal clinically important difference (MCID).

Results

The CAT algorithms accurately estimated 12-item questionnaire scores from between four and nine items. Scores followed a very similar distribution between CAT and full-length assessments, with the mean score difference ranging from 0.03 to 0.26 out of 48 points. Pearson’s correlation coefficient and ICC were 0.98 for each 12-item scale and 0.95 or higher for the OES subscales. In over 95% of cases, a patient’s CAT score was within five points of the full-length questionnaire score for each 12-item questionnaire.

Conclusion

Oxford Hip Score, Oxford Knee Score, Oxford Shoulder Score, and Oxford Elbow Score (including separate subscale scores) CATs all markedly reduce the burden of items to be completed without sacrificing score accuracy. Cite this article: Bone Jt Open 2022;3(10):786–794.

Published: October 2022

Highlights

CFD simulation was done for studying airflow uniformity during drying of aquatic feed in a belt dryer.

The simulation predicted the airflow distribution in different feed layers of the dryer well.

The fan frequency affected the moisture diffusivity and overall drying uniformity.

The fan frequency of 30 Hz resulted in the best drying process.

Abstract. Drying is an essential process in the production of aquatic feed products. Belt dryer is widely used in drying aquatic feed. The uniformity of airflow distribution inside the belt dryer affects the quality of dried products, the dryer efficiency, and energy consumption. Fan frequency was one of the critical factors affecting air distribution inside the dryer. However, the internal airflow distribution inside the belt dryer was not fully investigated, and air velocities were challenging to test accurately. The airflow distribution inside a belt dryer at four different fan frequencies (25, 30, 35, and 40 Hz) was studied with computational fluid dynamics (CFD) simulation and experimental verification. A finite volume method was employed to simulate airflow distribution inside the dryer. The porous medium model was added to improve result accuracy. The results showed that the simulated value of air velocity was consistent with the experimental value. The maximum gap between observed and simulated values was 7.24%, and the minimum was less than 0.1%. The air velocity on the feed layer ranged from 0.34 to 1.10 m s-1 with a standard deviation of up to 0.17 m s-1. When the fan frequency was 30 Hz, air velocity uniformity on the feed layer surfaces could reach the best results. Keywords: Airflow distribution, Belt dryer, CFD, Fan frequency, Porous media.
Automated Leaching Fraction-based Irrigation System Reduces Leaching, Conserves Water, and Supports Crop Growth in a Commercial Nursery
Authors: Cypher Quinn , Wright Wesley C. , Sun Xiaocun , Fessler Lauren , Fulcher Amy
Published: October 2022

Highlights

An automated irrigation system based on a novel leachate sensor was built to schedule and deliver irrigation to a container nursery.

The sensor network was designed to achieve a 0.15 leaching fraction; it maintained an actual average leaching fraction of 0.17.

Water use and container effluent were reduced by 60% and 96%, respectively, without reducing crop growth.

Abstract.With the aim of reducing irrigation water use, an irrigation and leachate measurement and control system was developed and evaluated to automatically schedule and actuate irrigation in a commercial nursery. Leachate and irrigation sensors were built using a tipping bucket mechanism and used to calculate the daily leaching fraction (LF) = volume leached/volume applied. For the experimental daily irrigation schedule, the previous day’s LF was used to calculate irrigation run time for the current day using a scaled multiplier, where the change in irrigation run time was proportional to the difference between the calculated LF and the target LF, 0.15. The control zone was irrigated for two hours every other day simulating the commercial nursery’s standard schedule. The irrigation control system worked as designed and correctly imposed the irrigation treatments, including correctly delaying in response to rain and actuating based on a programmed minimum runtime, when necessary. Season-long water use was 60% less for the leachate-based irrigation schedule compared to the grower’s standard irrigation schedule (p = 0.0028). The average daily LFs were 0.17 and 0.73 for the LF-based irrigation and control, respectively (p < 0.0001). Compared to the grower’s standard practice the time averaged irrigation application rate was 3.3-fold less and time averaged leaching rate was 12.1-fold less for the LF-based irrigation schedule. Substrate volumetric water content was not correlated with LF and thus was not a good predictor of leaching fraction. Growth metrics were not impacted by irrigation treatment (p = 0.1429), indicating plants received sufficient water in the LF-based irrigation system. This novel system was able to actuate and adjust irrigation run-time based on daily leaching fraction without being influenced by the lag between irrigation and leaching and had an average leaching fraction within 0.02 of the target LF. Reducing water use with this LF-based schedule has the potential to reduce agrichemical-laden nursery effluent and increase nursery irrigation capacity, i.e., their ability to expand production on the current water supply.

Published: October 2022

Conventional photon detectors necessarily face critical challenges regarding strong wavelength-selective response and narrow spectral bandwidth, which are undesirable for spectroscopic applications requiring a wide spectral range. With this perspective, herein, we overcome these challenges through a free-carrier absorption-based waveguide-integrated bolometer for infrared spectroscopic sensors on a silicon-on-insulator (SOI) platform featuring a spectrally flat response at near-infrared (NIR) range (1520-1620 nm). An in-depth thermal analysis was conducted with a systematic investigation of geometry dependence on the detectors. We achieved great performances: temperature coefficient of resistance (TCR) of -3.786%/K and sensitivity of -26.75%/mW with a low wavelength dependency, which are record-high values among reported waveguide bolometers so far, to our knowledge. In addition, a clear on-off response with the rise/fall time of 24.2/29.2 µs and a 3-dB roll-off frequency of ∼22 kHz were obtained, sufficient for a wide range of sensing applications. Together with the possibility of expanding an operation range to the mid-infrared (MIR) band, as well as simplicity in the detector architecture, our work here presents a novel strategy for integrated photodetectors covering NIR to MIR at room temperature for the development of the future silicon photonic sensors with ultrawide spectral bandwidth.
The U-Net-based phase-only CGH using the two-dimensional phase grating
Authors: Liu Xinlei , Yan Xingpeng , Wang Xi
Published: October 2022

In this paper, the phase-only holograms with clear first diffraction orders have been generated based on the U-Net and the two-dimensional phase grating. Firstly, we proved the modulation effect of two-dimensional phase grating on diffraction field, and came to a conclusion that it could move the diffraction pattern of the hologram to the odd-numbered diffraction orders’ center of that. Then we changed the generation process of phase-only holograms and the training strategy for U-Net according to this conclusion, which converted the optimization target of the U-Net from the zeroth diffraction order in the center of diffraction field to the first diffraction order in the edge of that. And we also used a method called “phase recombination” to improve the structure of U-Net for less memory footprint and faster generating speed. Finally, the holograms with the 4K resolution have been generated in 0.05s, and the average peak signal to noise ratio (PSNR) of the reconstructed images is about 37.2 dB in DIV2K-valid-HR dataset.

Published: October 2022

Introduction

On 21st March 2020, the first COVID-19 case was detected in Uganda and a COVID-19 pandemic declared. On the same date, a nationwide lockdown was instituted in response to the pandemic. Subsequently, more cases were detected amongst the returning international travelers as the disease continued to spread across the country. On May 14th, 2020, a cholera epidemic was confirmed in Moroto district at a time when the district had registered several COVID-19 cases and was in lockdown. This study aimed to describe the cholera epidemic and response activities during the COVID-19 pandemic as well as the hurdles and opportunities for cholera control encountered during the response.

Materials and methods

In a cross-sectional study design, we reviewed Moroto district’s weekly epidemiological records on cholera and COVID-19 from April to July 2020. We obtained additional information through a review of the outbreak investigation and control reports. Data were analyzed and presented in frequencies, proportions, attack rates, case fatality rates, graphs, and maps.

Results

As of June 28th, 2020, 458 cases presenting with severe diarrhea and/or vomiting were line listed in Moroto district. The most affected age group was 15–30 years, 30.1% (138/458). The females, 59.0% [270/458], were the majority. The Case Fatality Rate (CFR) was 0.4% (2/458). Whereas home use of contaminated water following the vandalization of the only clean water source in Natapar Kocuc village, Moroto district, could have elicited the epidemic, implementing COVID-19 preventive and control measures presented some hurdles and opportunities for cholera control. The significant hurdles were observing the COVID-19 control measures such as social distancing, wearing of masks, and limited time in the community due to the need to observe curfew rules starting at 6.00 pm. The opportunities from COVID-19 measures complementary to cholera control measures included frequent hand washing, travel restrictions within the district & surrounding areas, and closure of markets.

Conclusion

COVID-19 preventive and control measures such as social distancing, wearing of masks, and curfew rules may be a hurdle to cholera control whereas frequent hand washing, travel restrictions within the district & surrounding areas, and closure of markets may present opportunities for cholera control. Other settings experiencing concurrent cholera and COVID-19 outbreaks can borrow lessons from this study.
Occurrence of urinary schistosomiasis and associated bacteria in parts of Ondo State, Nigeria
Authors: Kone Kikelomo J. , Onifade Anthony K. , Dada Ebenezer O.
Published: October 2022

Schistosomiasis is a parasitic disease caused by blood flukes (trematode worms) of the genus Schistosoma and is common among the rural community dwellers that have occupation or recreation activities that link them with infected water bodies. The disease wreak a lot of havoc in the victims which range from anaemia, increase risk of liver fibrosis and bladder cancer, enlarged liver, difficult and painful urination, infertility etc. Nigeria has been reported to be the most endemic country in the world for schistosomiasis with about 29 million infected cases. However, people with urinary schistosomiasis are vulnerable to secondary infections caused by bacteria as a result of the break down in the mucosa barrier occasioned by the wear and tear of the spiny eggs of the schistosomes. Meanwhile, the control measures instituted by various agencies against schistosomiasis paid little attention to its co-infection with bacteria. This study was designed to evaluate the occurrence of urinary schistosomiasis and co-infection with bacteria in parts of Ondo State, Nigeria. Ethical approval was obtained from the Ethical Committee of the Ondo State Ministry of Health, Akure. Macroscopic and microscopic examinations, and microbiological analysis of the urine samples collected were performed using standard techniques. Of the five hundred and nine (509) urine collected, ova of Schistosoma haematobium were detected in one hundred and twenty one 121 (23.77%), significant bacteriuria was detected in 104 (20.43%) and co-infection was detected in thirty six 36 (29.75%) of schistosomiasis cases. There was a positive association between urinary schistosomiasis and bacteriuria (X2(1) = 8.481, p = 0.004). This study revealed a high occurrence of urinary schistosomiasis and significant bacteriuria in the study areas which suggests that bacterial presence may be a potent complication in the management of urinary schistosomiasis.
A systematic review and quality appraisal of the economic evaluations of schistosomiasis interventions
Authors: Uzoegbo Sharon C. , Jackson Louise J. , Bloch Sonja C. M.
Published: October 2022

Background

Schistosomiasis is a neglected tropical disease (NTD) that affects over 230 million people in low and middle-income countries (LMICs) and can lead to long-term debilitating health effects. It is associated with impoverishment and has been prioritised by the World Health Organization for prevention, control and elimination. This systematic review aimed to identify and evaluate existing economic evaluations of interventions to tackle schistosomiasis.

Methodology

A comprehensive search strategy of four databases and additional hand-searching was employed on the 17th July 2020. The articles were screened and sorted using a two-stage classification system. Full economic evaluations published in English between 1st January 1998 and 17th July 2020 were included, and methodological quality was appraised using the international decision support initiative (iDSI), Phillips and Evers checklists.

Results

Eighteen economic evaluations were identified, nine trial-based and nine model-based, with the majority focused on preventative chemotherapy. Schistosomiasis interventions were collectively found to be cost-effective, but the quantity and quality of studies were limited. The outcome measures and time-horizons utilised varied substantially making comparison difficult. The majority of papers failed to address equity and affordability.

Conclusion

Several methodological issues were highlighted which might have implications for optimal decision-making. Future research is needed to ensure the standardisation of methods, in order to ensure that scarce healthcare resources are focused on the most cost-effective programmes to tackle schistosomiasis and other NTDs.

Published: October 2022

Background

Tuberculosis (TB) remains the leading cause of death among human immunodeficiency virus (HIV) infected individuals in South Africa. Despite the implementation of HIV/TB integration services at primary healthcare facility level, the effect of HIV on TB treatment outcomes has not been well investigated. To provide evidence base for TB treatment outcome improvement to meet End TB Strategy goal, we assessed the effect of HIV status on treatment outcomes of TB patients at a rural clinic in the Ugu Health District, South Africa.

Methods

We reviewed medical records involving a cohort of 508 TB patients registered for treatment between 1 January 2013 and 31 December 2015 at rural public sector clinic in KwaZulu-Natal province, South Africa. Data were extracted from National TB Programme clinic cards and the TB case registers routinely maintained at study sites. The effect of HIV status on TB treatment outcomes was determined by using multinomial logistic regression. Estimates used were relative risk ratio (RRR) at 95% confidence intervals (95%CI).

Results

A total of 506 patients were included in the analysis. Majority of the patients (88%) were new TB cases, 70% had pulmonary TB and 59% were co-infected with HIV. Most of HIV positive patients were on antiretroviral therapy (ART) (90% (n = 268)). About 82% had successful treatment outcome (cured 39.1% (n = 198) and completed treatment (42.9% (n = 217)), 7% (n = 39) died 0.6% (n = 3) failed treatment, 3.9% (n = 20) defaulted treatment and the rest (6.6% (n = 33)) were transferred out of the facility. Furthermore, HIV positive patients had a higher mortality rate (9.67%) than HIV negative patients (2.91%)”. Using completed treatment as reference, HIV positive patients not on ART relative to negative patients were more likely to have unsuccessful outcomes [RRR, 5.41; 95%CI, 2.11–13.86].

Conclusions

When compared between HIV status, HIV positive TB patients were more likely to have unsuccessful treatment outcome in rural primary care. Antiretroviral treatment seems to have had no effect on the likelihood of TB treatment success in rural primary care. The TB mortality rate in HIV positive patients, on the other hand, was higher than in HIV negative patients emphasizing the need for enhanced integrated management of HIV/TB in rural South Africa through active screening of TB among HIV positive individuals and early access to ART among HIV positive TB cases.
Too few, too late: U.S. Endangered Species Act undermined by inaction and inadequate funding
Authors: Eberhard Erich K. , Wilcove David S. , Dobson Andrew P.
Published: October 2022

This year, the Conference of Parties to the Convention on Biological Diversity will meet to finalize a post 2020-framework for biodiversity conservation, necessitating critical analysis of current barriers to conservation success. Here, we tackle one of the enduring puzzles about the U.S. Endangered Species Act, often considered a model for endangered species protection globally: Why have so few species been successfully recovered? For the period of 1992–2020, we analyzed trends in the population sizes of species of concern, trends in the time between when species are first petitioned for listing and when they actually receive protection, and trends in funding for the listing and recovery of imperiled species. We find that small population sizes at time of listing, coupled with delayed protection and insufficient funding, continue to undermine one of the world’s strongest laws for protecting biodiversity.
Transition from BOS to RAS impairs prognosis after lung transplantation—CLAD subtype analysis by CT volumetry
Authors: Peräkylä Laura , Nykänen Antti , Piilonen Anneli , Kesävuori Risto , Halme Maija , Raivio Peter
Published: October 2022

Background

Chronic lung allograft dysfunction (CLAD), subclassified into bronchiolitis obliterans syndrome (BOS) or restrictive allograft syndrome (RAS), limits survival after lung transplantation. Information concerning transition from BOS to RAS is limited. We aimed to characterize the lung volume change after BOS diagnosis by computed tomography (CT) volumetry and to determine the incidence, risk factors and clinical significance of BOS to RAS transition.

Methods

CT volumetry measurements were performed from 63 patients with CLAD initially classified as BOS by CT volumetry. BOS patients with lung volume remaining >85% of baseline were classified as persistent BOS, whereas BOS patients whose lung volume permanently decreased to ≤85% of baseline were classified as BOS to RAS transition.

Results

During follow-up (median 9.8 years) eight patients (12.7%) were classified as BOS to RAS transition, which decreased recipient (p = 0.004) and graft survival (p = 0.020) in comparison to patients with persistent BOS. Opacities on chest imaging preceded BOS to RAS transition in 88% of patients. Opacities on chest imaging at BOS diagnosis and early CLAD diagnosis after transplantation were risk factors for transition.

Conclusion

Based on lung volume decrease measured by CT volumetry, a small proportion of BOS patients transitioned to RAS which had an adverse effect on recipient and graft survival.
Exhibition as cinema, cinema as exhibition: Philippe Parreno and the moving image in the museum
Authors: Smith Olga
Published: October 2022

This article situates a number of Philippe Parreno’s moving image installations within the developments that led in the 1990s to the establishment of film as one of the pre-eminent forms of display in the museum of contemporary art. From here, a clear yet unexplored relation is established between cinema’s relocation to the museum and artistic practices promoted under the conceptual label of relational aesthetics, with which Parreno was closely associated throughout the 1990s. Conceived as a part of the structural whole comprising an exhibition and embedded in a specific location, film installation was used by Parreno to raise questions concerning the visibility of the artwork and the duration of the viewing encounter. The fluid interactions between temporal and spatial categories in these installations invite a re-examination of the categories of museum and exhibition, as well as the material limits of the medium of the moving image.

Classifying Latent Profiles of Career Barriers Perceived by Multicultural Youths and Verifying Differences in Career Attitude: Focused on high school students
Authors: Ha Yeojin
Published: October 2022

The purposes of this research were to explore latent profiles according to multicultural youths' perceived career barriers and to identify the effect of ecological variables. Differences in their career attitude were also verified. To meet these purposes, the Multicultural Adolescents Panel Study data from 7th to 8th waves were analyzed by applying latent profile analysis. The major findings were as follows: First, the perceived career barriers showed three latent profiles; the high level career barrier group, the middle level career barrier group, and the low level career barrier group. Second, the significantly affected factors determining these groups were self-esteem, life satisfaction, depression, social withdrawal, achievement motivation, educational expectation, household income, parent’s neglecting attitude, cultural adaptation stress, and social supporter. Third, the level of career determination and career preparation were significantly different according to the level of perceived career barriers. Based on these results, implications of this study were discussed.

Authors: Lim Jeongsoo , Park Hyung-joon , Mo Kyung-hwan
Published: October 2022

The purpose of the present study is to analyze the content of social minority groups in high school ‘Society and Culture’ textbooks and to provide suggestions for improving textbook development. The results of analysis are as follows. First, the definition of the concept subsumes current sociological theories, but the conceptual features such as complexity, relativity, intersectionality, and variability are scarcely discussed. Second, social minorities are categorized as outgroup members and they are labeled as “them.” Third, examples of the social minority are focused mostly on persons with disabilities and foreign workers. Fourth, the visions of citizenship pursued by the textbooks are conservative. Active citizenship should be emphasized so that students are encouraged to be more engaged with the people around them and change the world for the better.

Analysis of the Determinants of Career Planning and the Long-Term Stay for International Students
Authors: Song Hae-ryeon
Published: October 2022

The main purpose of this research is to analyze the determinants of career planning and the long-term stay for international students. To analyze it, we use 2020 survey on Immigrants’ Living Conditions and Labour Force and logistic regression is used. The main findings are as follows: First, crucial variables of career planning after graduation differ as which categories belong to. Major, nationalities, language and the motivation of studying aboard are decisive variables for foreign students who decide to go back. However, students who have a plan to go to another country consider major and satisfaction of education in Korea as the key variables. Second, a common factor of the 1st analysis is major. Third, the determinants of the long-term stay are the level of education, age, length of stay, and language. Variables that belong to language categories are also how long they have learned Korean, speaking skill and language problems have effect on the decision of the long-term stay, but they are not the most decisive variables. Based on these results, this paper suggests a variety of policy implications related to international students.

Authors: Castaño Serna Juan Pablo , Rubio Clemente Ainhoa , Chica Arrieta Edwin
Published: October 2022

Contexto: Los paneles solares fotovoltaicos bifaciales pueden generar más energía que los monofaciales, ya que, en el primer caso, ambos lados del panel quedan a disposición para captar la irradiancia solar y transformarla en energía eléctrica. La potencia adicional que se puede generar en los paneles bifaciales depende, entre otros factores, de la naturaleza y el tipo de la superficie reflectiva, así como de la orientación del módulo fotovoltaico.
Método: En este trabajo se evalúan diversas superficies reflectantes para determinar la configuración óptima de un panel bifacial. Para este propósito, y con base en la metodología de superficie de respuesta, las curvas características del panel fotovoltaico (corriente-voltaje) para diversas elevaciones con respecto a cuatro superficies reflectantes son trazadas experimentalmente.
Resultados: Los resultados del estudio revelan que, al instalar un panel bifacial sobre superficies reflectantes de espejo a una elevación del 98,66 % del ancho del panel, se logra alcanzar un aumento del 6,6 % de la generación de energía eléctrica en comparación con los módulos fotovoltaicos monofaciales.
Conclusiones: Con la metodología aplicada, se identificó que la superficie de espejo es la mejor de las cuatro superficies evaluadas para el aprovechamiento de la irradiación reflejada, seguida por el concreto, el agua y la tierra.

Published: October 2022

Pregnancy in women with hypertrophic cardiomyopathy is not well described. In this retrospective study, we analyzed data on pregnant women with hypertrophic cardiomyopathy who were under follow-up care in the cardiology department of a tertiary care hospital. We reviewed data on all women registered in the hypertrophic cardiomyopathy cohort and those who attended the cardio-obstetric clinic and delivered between January 2010 and June 2019. From these 2 groups, we identified 7 pregnant women with hypertrophic cardiomyopathy who delivered during this period. These 7 women (mean [SD] age, 25 [3.3] years) had a total of 15 pregnancies (range per woman,1–4). This was a high-risk cohort, as 7 (46.7%) pregnancies were in the modified World Health Organization class III. The mean (SD) left ventricular wall thickness was 19.71 (2.56) mm in all pregnancies. Two of the 7 women with left ventricular outflow tract obstruction developed severe symptoms in the third trimester; these improved soon after delivery. Eight pregnancies without obstruction were well tolerated. Two pregnancies occurred after successful alcohol septal ablation. Both remained asymptomatic throughout pregnancy. All women tolerated labor well. Adverse maternal outcomes, including death, were not seen in any patient. All women who became symptomatic during pregnancy had relief of symptoms after delivery. Most women remained asymptomatic or had mild symptoms during pregnancy. Of the women with left ventricular outflow tract obstruction, 28.6% had severe symptoms that improved after delivery. Pregnancy was well tolerated after successful alcohol septal ablation.

Published: October 2022

The transcatheter aortic valve replacement procedure is used in patients with aortic stenosis. Transcatheter aortic valve replacement devices are quite versatile; thus, they are increasingly being used for nonaortic applications, such as tricuspid valve-in-valve implantation. This case series describes a transcatheter aortic valve replacement procedure in 4 patients with anatomic challenges (eg, aortic tortuosity, high valvular calcium burden, highly calcified bicuspid valve, low coronary artery takeoff, left main coronary artery occlusion, and large aortic annulus) and a fifth patient who had a failed tricuspid bioprosthesis and underwent a tricuspid valve-in-valve implantation with the Edwards SAPIEN 3 transcatheter heart valve (Edwards Lifesciences). All procedures required adjustments to the standard protocol, and each procedure was successful. The critical, technical adjustments in the deployment technique and preprocedural planning of the procedures are detailed to provide a road map for other cardiologists who encounter similar challenges.
Usefulness of 3-Dimensional Reconstruction Images of Coronary Computed Tomography Angiogram in Percutaneous Coronary Intervention After Bentall Operation
Authors: Sugimura Kazunori , Miyasaka Masaki , Nakashima Masaki , Tada Norio
Published: October 2022

Anastomotic complications of the coronary arteries were observed in approximately 5% of patients undergoing Bentall-type surgery. Given the high surgical risk of reoperation, percutaneous coronary intervention could be a treatment for anastomotic complications but is challenging because of the complicated anatomy after Bentall-type surgery. Here, a 70-year-old man underwent a Bentall operation during which the left main coronary artery was accidentally injured. Therefore, coronary artery bypass using a saphenous vein graft was performed. The saphenous vein graft was anastomosed from the right side of the aortic graft to the left main coronary artery. Three years later, the patient presented with an anterior non–ST-segment elevation myocardial infarction. Because his unusual anatomy, the saphenous vein graft could not be cannulated with diagnostic catheters, even after perusing the surgical record of the Bentall surgery. Subsequently, coronary computed tomography angiography was performed. Three-dimensional reconstructed images visualized the positional relationship between the saphenous vein graft and anatomical landmarks, such as the implanted surgical valve prosthesis. The angiogram angle was adjusted using these landmarks and projection angles estimated by the images. Then, the ASAHI Hyperion Judkins right 4 catheter could be easily inserted, and percutaneous coronary intervention was successfully performed. Three-dimensional reconstruction images were useful for performing percutaneous coronary intervention by aiding in the identification of the anatomic location of the saphenous vein graft and the positional relationship between the saphenous vein graft and anatomic landmarks. In patients with unusual anatomy, as in this case, coronary computed tomography angiography should be strongly considered.

Educational Robotics (ER) has gained prominence in the literature on Computational Thinking (CT) because of its modularity, a feature that potentially facilitates the development of abstract thinking through complex robotic parts. The field of robotics encompasses the characteristics of technology, intelligence, embodiment, and interaction, and these characteristics can serve as means of instruction for CT. Essential 21st Century Skills include decomposition, pattern recognition, abstraction, and the use of algorithms; which are fundamental to effective problem-solving skills. Although CT is believed to be the key to developing 21st Century Skills, its role in doing so is significantly underexplored. This paper investigates the influence of CT ability on students’ efficacy in imbibing 21st Century Skills. The study implemented a qualitative case study design, in which students of an Indonesian vocationaleducation school were engaged in ER activities. CT skills and the associated 21st Century Skills were evaluated through several phases of observation and interviews. The findings reveal that CT paves the way for the development of 21st Century Skills. Analysing the development of CT can be a major way in which individuals are empowered to take full advantage of the developments brought about by rapid changes in technology.

We highlight the benefits of 3D printing in classrooms and opportunities for developing different knowledge and skills, starting from mathematical and technological knowledge to communication and collaboration skills. During our activities, we used GeoGebra for 3D printing preparations, it was also utilized for online students’ activities, while supporting theoretical background students gained in real classrooms. Since 3D printing technology in the classroom is at its beginnings, the presented observations are highlighting teaching new kinds of strategies supported by 3D printing.
Geographical determinants and hotspots of out-of-school children in Nigeria
Authors: Adeleke Richard , Alabede Opeyemi
Published: October 2022

In Nigeria, children lack access to primary school education, and this hinders their social, cognitive, emotional, and physical skills’ development. With one in every five of the world’s out-of-school children in Nigeria, achieving universal primary education by 2030 remains a challenge. Several studies have investigated the factors that have led to an increase in out-of-school children (OOSC); however, these studies are based on individual level and household predictors with little evidence on the geographical determinants. Hence, this study examines the relationship between OOSC and the socio-economic attributes of the geographical location where they reside. Findings of the spatial analysis show that Sokoto, Zamfara, Yobe, Taraba, and Plateau are the hotspots of out-of-school children. The result further reveals that there is spatial variation in the predictors of out-of-school children in the country. Poverty and internally generated revenue (IGR) predict more cases of school non-attendance in northern Nigeria while foreign direct investment determines the number of children that are out-of-school in the southern region. The study recommends spatially explicit policies to reduce the number of OOSC in Nigeria.

In this paper, the exact analytical solutions to the generalized Schrödinger equation are investigated. The Schrodinger type equations bearing nonlinearity are the important models that flourished with the wide-ranging arena concerning plasma physics, nonlinear optics, fluid-flow, and the theory of deep-water waves, etc. In this exploration, the soliton and other traveling wave solutions in an appropriate form to the generalized nonlinear Schrodinger equation by means of the extended sinh-Gordon equation expansion method, tan(Γ(ϖ))-expansion method, and the improved cos(Γ(ϖ)) function method are obtained. The suggested model of the nonlinear Schrodinger equation is turned into a differential ordinary equation of a single variable through executing some operations. One soliton, periodic, and singular wave solutions to this important equation in physics are reached. The periodic solutions are expressed in terms of the rational functions. Soliton solutions are obtained from them as a particular case. The obtained solutions are figured out in the profiles of 2D, density, and 3D plots by assigning suitable values of the involved unknown constants. Modulation instability (MI) is employed to discuss the stability of got solutions. These various graphical appearances enable the researchers to understand the underlying mechanisms of intricate phenomena of the leading equation. The individual performances of the employed methods are praiseworthy which deserves further application to unravel any other nonlinear partial differential equations (NLPDEs) arising in various branches of sciences. The proposed methodologies for resolving NLPDEs have been designed to be effectual, unpretentious, expedient, and manageable.

Der Artikel nimmt Migrationsbewegungen vor allem der Christinnen und Christen in den Blick, die durch das Erstarken des sog. IS ausgelöst worden sind. Durch sie werden die Folgen migratorischer Bewegungen für die christliche Landschaft in den Ländern des Nahen Ostens selbst, genauso Veränderungen innerhalb der religiösen Landschaft in Deutschland offensichtlich. Diese Entwicklungen fordern ökumenisches Nachdenken heraus.
Migration und Mission aus freikirchlicher Sicht
Authors: Kißkalt Michael
Published: October 2022

In den freikirchlichen Kontexten in Deutschland haben sich in den letzten Jahren bzw. Jahrzehnten eine Reihe von Migrationsgemeinden entwickelt. Am Beispiel des Bundes Evangelisch-Freikirchlicher Gemeinden wird deutlich, dass die Integration dieser oft sehr missionarischen Gemeinden sowohl strukturell als auch theologisch gut gelingt, auch wenn es eine Reihe von Herausforderungen gibt, die man gemeinsam angehen muss. Bei gelingender Integration werden sich die Freikirchen auf die Dauer verändern.
Oxygen-supplied electrotherapy for enhanced photodynamic synergistic therapy overcomes hypoxia tumor microenvironment

Published: October 2022

Photodynamic therapy (PDT) has lately been identified as a promising anticancer method and gained tremendous interest due to its controllability, non-invasive nature, and negligible side effects. Nevertheless, the development of PDT is hampered by two factors. One is the insufficient tissue penetration of phototherapy laser, resulting in restricted treatment sites. Another one is the substantial dependence of reactive oxygen species (ROS) formation on oxygen concentration. Therefore, a strategy to promote ROS generation by overcoming the hypoxia microenvironment is critical to cancer therapy. Electrolysis of water is known to be a rapid and relatively secure method for producing oxygen. Thus, in this study, electrotherapy was introduced to alleviate the tumor hypoxia by producing oxygen in situ, hence boosting the PDT efficacy, namely E-PDT. Black phosphorus (BP) based nanomaterials were selected as clearable photosensitizers with outstanding PDT performance. Experiments conducted both in vitro and in vivo indicated that E-PDT performed superior therapeutic effects with the in situ generation of oxygen by electrotherapy compared with other groups. This work suggests a promising strategy for phototherapeutic anticancer efficiency enhancement.
