Designing a Partly Self-Powered Keyboard Based on Triboelectric Effect
Authors:   Hanoi University of Science and Technology
Published: September 2021

The purpose of this paper is to design a keyboard using the triboelectric effect (Tribo Electric Nano Generator - TENG) to collect a part of the energy from keystrokes to reduce the power consumption of the keyboard. Using elastic material as the cover on the keyboard to maximize the capture of energy from typing. The keyboard layers are made from common materials such as Al (Aluminum) and PTFE (Polytetrafluoroethylene). The built-in 16-button keyboard ensures the same typing speed as a typical keyboard. Based on selected triboelectric material, the output voltage of keyboard was simulated and processed by using a signal detection circuit. The results show that the average voltage generated by each key with electrical friction effect is about 4 V, the power consumption for the detection circuit is about 0.32 W. In addition, the keystroke signals were sent and displayed correctly on the designed software on the computer.
ASSESSING THE POSSIBILITY OF DETERMINING YOUNG TREES PLANTING TERMS BASED ON THE POST-PLANTING ADAPTATION OF THEIR SHOOT SYSTEMS

Published: September 2021

Для учета и обследований городских насаждений необходимы методики определения сроков посадки молодых деревьев без нанесения повреждений растениям и при отсутствии хозяйственных документов о посадках. В статье представлена оценка перспективности использования эффекта послепосадочной адаптации побеговых систем молодых деревьев, выраженного в укорочении годичных приростов, для определения сроков посадки. Приводятся результаты исследования побеговых систем трех видов хвойных и четырех видов лиственных древесных растений, высаженных на территорию парка УрГПУС в г. Екатеринбурге с 2011 по 2019 гг. На нескольких скелетных ветвях каждого обследованного молодого дерева определяли периоды с наиболее короткими линейными приростами и сопоставляли их с приведенными в документах о посадках и состоянием растений. Установлено, что все сохранившиеся с момента создания посадок обследованные деревья реагировали на пересадку укорочением линейного прироста боковых ветвей. Более короткие годичные побеги встречаются на разных ветвях одного дерева синхронно и по документам совпадают по времени с периодом непосредственно после пересадки. Формирование укороченных линейных приростов у молодых деревьев не связано с погодными условиями, так как у разных обследованных деревьев это происходило в разные годы. На окружающих взрослых деревьях, растущих на одном месте длительный срок, аналогичных зон на побегах не обнаружено. Та- ким образом, эффект формирования укороченных годичных приростов в период адаптации молодых растений может быть основанием для установления срока их посадки при отсутствии документов и без нанесения повреждений.
High speed, high precision processing of dry pre-pregs for composite structures
Authors:   , Ramsaroop Avinash
Published: September 2021

In this study, a computational code was developed that was used to optimise the fibre orientation angles, layer thicknesses, number of fibre layers and the weight in fibre reinforced composites. In addition, an interface was created between the computational code and the robotic apparatus that performed the fibre placement. Fibre reinforced composites are extremely versatile materials and may be tailor designed to suit various applications. However, the design techniques commonly associated with composite structures make them inadequate for industries with high production rates. Conventional design techniques have the disadvantage of numerous tedious and laborious matrix calculations. Also, there is uncertainty with assigning values to the input parameters for the equations used in the design process. In addition, conventional design techniques result in constant stiffness structures, that is, structures with the same fibre layup throughout. These disadvantages result in increased manufacturing costs as more material and labour, than necessary, are used. This study presents a solution in the form of computational codes developed in Matlab. The codes are used to perform all the necessary matrix calculations easily and swiftly. Further, the uncertainty experienced with the input parameters, in conventional design techniques, is removed. The code is used to optimise the fibre orientation angles and layer thicknesses in a composite structure, as well as the number of fibre layers and the weight. In addition, it is able to create variable stiffness structures, that is, structures where the fibre layup varies throughout. The use of the code in the design process would decrease the design costs, as the design time is reduced, and decrease the material costs, as only the required amount of material is used. The developed codes were validated using examples from texts, finite element modelling and experimental methods. The development of the computational codes created a problem with regards to the fibre layup process. Any process that employed manual placement of the fibres became inadequate as they proved to be extremely labour intensive and would result in increased labour costs. Further, with manual placement of fibres, precise fibre orientation cannot be guaranteed. Therefore it was decided to use an automated system, such as Robotic Fibre Placement (RFP), to perform the fibre layup. Such a system was designed and built in-house in a previous study. In the current study, a Matlab code was developed as an interface between the developed computational code and the fibre placement system. Other codes as well as graphical interfaces were developed in order to improve the interaction between the user and the codes.
The hegemonic position of English as a medium of instruction at primary school level in KwaZulu-Natal, and its impact on parents' preferences of schooling for their children
Authors:   , Naidoo Jeevarathanum
Published: September 2021

This study is concerned with the choices parents of second language learners make with regard to the schooling of their children in respect of medium of instruction, and explores the reasons why parents choose to disregard education in their mother tongue in favour of English as a medium of instruction. This is contrary to the Language in Education Policy, as the Department of Education instils in principals, educators and parents the need for children at primary school level to be taught in their mother tongue. The theoretical framework used to address the problem was the Critical Language Approach, this being an appropriate position from which to investigate language and power. A combination of questionnaires, interviews and observation was used to acquire data from parents and management in a large primary school in KwaZulu-Natal. After analysis of the data, which confirmed the hegemonic position of English as influencing choice of medium of instruction by parents of English second language learners, a model was developed to assist them to see the possible consequences of various choices. The model comprised a tenpoint questionnaire to identify needs, a flow chart diagram resulting from the needs analysis, a pictograph to assist stakeholders to understand the relevant choices available, and workshops to support the choice of medium of instruction. The value of the research, it is thought, lies in clarifying the various influences at play, in particular, the hegemonic position of English, and offering stakeholders a rational, rather than political or emotional basis for the choice of medium of instruction for second language learners, as well as pointing out the possible consequences of such choices.

Published: September 2021

Abstract. Aerosols can enhance ecosystem productivity by increasing diffuse radiation. Such diffuse fertilization effects (DFEs) vary among different aerosol compositions and sky conditions. Here, we apply a suite of chemical, radiation, and vegetation models in combination with ground- and satellite-based measurements to assess the impacts of natural and anthropogenic aerosol species on gross primary productivity (GPP) through DFE during 2001–2014. Globally, aerosols increase GPP by 8.9 Pg C yr-1 at clear skies but only 0.95 Pg C yr-1 at all skies. Anthropogenic aerosols account for 41% of the total GPP enhancement though they contribute only 25% to the increment of diffuse radiation. Sulfate/nitrate aerosols from anthropogenic sources make dominant contributions of 33% (36%) to aerosol DFE at all (clear) skies, followed by the ratio of 18% (22%) by organic carbon aerosols from natural sources. In contrast to other species, black carbon aerosols decrease global GPP by 0.28 (0.12) Pg C yr-1 at all (clear) skies. Long-term simulations show that aerosol DFE is increasing 2.9% yr-1 at all skies mainly because of a downward trend in cloud amount. This study suggests that the impacts of aerosols and cloud should be considered in projecting future changes of ecosystem productivity under varied emission scenarios.
Albedo susceptibility of Northeastern Pacific stratocumulus: the role of covarying meteorological conditions
Authors: Zhang Jianhao , Zhou Xiaoli , Feingold Graham
Published: September 2021

Abstract. Quantification of the radiative adjustment of marine low-clouds to aerosol perturbations, regionally and globally, remains the largest source of uncertainty in assessing current and future climate. An important step towards quantifying the role of aerosol in modifying cloud radiative properties is to quantify the susceptibility of cloud albedo and liquid water path (LWP) to perturbations in cloud droplet number concentration (Nd). We use 10 years of space-borne observations from the polar-orbiting Aqua satellite, to quantify the albedo susceptibility of marine low-clouds over the northeast (NE) Pacific stratocumulus region to Nd perturbations. Overall, we find a low-cloud brightening potential of 20.8 ± 0.96 W m−2 ln(Nd)−1, despite an overall negative LWP adjustment for non-precipitating marine stratocumulus, owing to the high occurrence (37% of the time) of thin non-precipitating clouds (LWP < 55 g m−2) that exhibit brightening. In addition, we identify two more susceptibility regimes, the entrainment-darkening regime (36% of the time), corresponding to negative LWP adjustment, and the precipitating-brightening regime (22% of the time), corresponding to precipitation suppression. The influence of large-scale meteorological conditions, obtained from the ERA5 reanalysis, on the albedo susceptibility is also examined. Over the NE Pacific, clear seasonal covariabilities among meteorological factors related to the large-scale circulation are found to play an important role in grouping favorable conditions for each susceptibility regime. Our results indicate that, for the NE Pacific stratocumulus deck, the strongest positively susceptible cloud states occur most frequently for low cloud top height (CTH), the highest lower-tropospheric stability (LTS), low sea-surface temperature (SST), and the lowest free-tropospheric relative humidity (RHft) conditions, whereas cloud states that exhibit negative LWP adjustment occur most frequently under high CTH and intermediate LTS, SST, and RHft conditions. The warm rain suppression driven cloud brightening is found to preferably occur either under unstable atmospheric conditions (low LTS) or high RHft conditions that co-occur with warm SST. Mutual information analyses reveal a dominating control of LWP, Nd and CTH (cloud state indicators) on low-cloud albedo susceptibility, rather than of the meteorological factors that drive these cloud states.

Abstract. This paper describes Nemo-Nordic 2.0, an operational marine model for the Baltic Sea.
The model is used for both near-real-time forecasts and hindcast purposes. It provides estimates of sea surface height, water temperature, salinity, and velocity, as well as sea ice concentration and thickness.
The model is based on the NEMO (Nucleus for European Modelling of the Ocean) circulation model and the previous Nemo-Nordic 1.0 configuration by Hordoir et al. (2019). The most notable updates include the switch from NEMO version 3.6 to 4.0, updated model bathymetry, and revised bottom friction formulation.
The model domain covers the Baltic Sea and the North Sea with approximately 1 nmi resolution. Vertical grid resolution has been increased from 3 to 1 m in the surface layer. In addition, the numerical solver configuration has been revised to reduce artificial mixing to improve the representation of inflow events. Sea ice is modeled with the SI3 model instead of LIM3.
The model is validated against sea level, water temperature, and salinity observations, as well as Baltic Sea ice chart data for a 2-year hindcast simulation (October 2014 to September 2016). Sea level root mean square deviation (RMSD) is typically within 10 cm throughout the Baltic basin. Seasonal sea surface temperature variation is well captured, although the model exhibits a negative bias of approximately −0.5 ∘C. Salinity RMSD is typically below 1.5 g kg−1. The model captures the 2014 major Baltic inflow event and its propagation to the Gotland Deep. The model assessment demonstrates that Nemo-Nordic 2.0 can reproduce the hydrographic features of the Baltic Sea.
Los senderos lúdicos que se bifurcan: el juego como mundo y el laberinto como estructura primordial
Authors: Planells de la Maza Antonio José
Published: September 2021

El laberinto ha sido tradicionalmente una de las estructuras físicas, psicológicas y simbólicas más relevantes y enigmáticas del mundo cultural occidental. Fértil como marco mítico para la literatura y el cine, apenas se ha explorado su impacto en el diseño de los videojuegos contemporáneos. Por ello, en este artículo exploramos cómo el laberinto, entendido como criterio de diseño físico y mítico, ha inspirado el videojuego tanto desde la perspectiva ludológica e interactiva como desde la visión simbólica de los mundos ludoficcionales. A partir de la herencia del juego analógico y los primeros videojuegos, realizamos una primera delimitación conceptual entre juego unicursal o labyrinth, multicursal o maze y rizomático. Acto seguido, aplicamos las dos primeras figuras al videojuego actual y analizamos las figuras centrales del mito – Teseo, el Minotauro y Ariadna – y su rol en la conformación de viejas y nuevas heroicidades, la concepción de la otredad y el mal y el juego como sendero vital interactivo.

La integración de las competencias clave en la educación artística no es solo un deber del ámbito formal, los contextos no formales deben actuar en la misma dirección. La presente investigación expone un análisis de la acción educativa de los museos de Matanzas (Cuba) cuyo objetivo es la evaluación de las competencias clave presentes en su diseño e implementación didáctica. La muestra no probabilística se compone de N=5 instituciones museísticas: el Museo de Arte, Palacio de Junco, El Morrillo, Castillo de San Severino. Museo de la Ruta del esclavo y Museo Farmacéutico; 5 directivos y 18 especialistas. Esta evaluación se desarrolla mediante un estudio multicaso de método mixto, compuesto por un instrumento con 6 indicadores y 18 descriptores, que evalúa el grado de adecuación de los diseños educativos a una mediación basada en competencias y permite conocer de forma pormenorizada el método de trabajo, las estrategias y los discursos educativos en la enseñanza del patrimonio, mediante la observación, entrevista estructurada y grupo de discusión. Los principales resultados identifican las competencias más presentes y las susceptibles de mejora contribuyendo a mejorar el trabajo educativo que realizan los museos, y suponen un estado de la cuestión pionero en el contexto cubano.
Educación estética / educación artística. Perspectivas curriculares superpuestas de la enseñanza del arte en la escuela primaria de la provincia de Buenos Aires (1984-1999)
Authors: Merlos Lucía
Published: September 2021

Singularizando el lugar del arte en el contexto escolar argentino, particularmente en la provincia de Buenos Aires, nos proponemos indagar perspectivas curriculares de finales del siglo XX. Específicamente nos interesa identificar y analizar las consideraciones de su enseñanza en los documentos producidos entre 1984 y 1999. Interpelar la consideración de Educación Estética que proponen los documentos del período 1984-1987, y las fundamentaciones de Educación Artística que presentan las publicaciones producidas entre 1995-1999. Partimos de la hipótesis de que entre una y otra denominación encontramos superposiciones de sentidos en los discursos pedagógicos sobre la presencia y las funciones del arte en la escolaridad bonaerense. A la luz de nuestro objetivo principal, elaboramos un mapeo de los diferentes lineamientos oficiales, esto es presentación, descripción y ordenamiento de los mismos, desde una mirada etnográfica sobre los documentos, que implica reconocer aquello que se produce en el campo de lo estatal como un campo de investigación en sí (Muzzopapa E., Villalta C., 2011).

Authors: Biedermann Anna Maria , Szostak Anna Januchta
Published: September 2021

This study examines Great Cultural Projects (GCPs) as an element of the developmental process of cities. For this study, GCPs are regarded as a global phenomenon rather than cases that must be analyzed independently. The study focused on four types of GCPs: world and international exhibitions, horticultural exhibitions, Olympic Games, and the European Capitals of Culture. The research sample comprised 183 GCPs globally, organized between the middle of the 19th century to the beginning of the 21st century. The study analyzed the influence of different GCPs on city structure and urban heritage and focused on the distinctive development of each GCP type. The study’s novelty lies in recognition of the four main types of GCPs’ potential for multidimensional urban development and their diversified impact on the transformation of modern cities, along with the identification of potential threats, benefits, and development opportunities related to different GCP types.

Published: September 2021

El articulo muestra la experiencia de una iniciativa de fotografía participativa con personas con discapacidad visual realizado en la ciudad de Bucaramanga-Colombia. Este trabajo buscó aportar a la reivindicación de los sujetos a través de la experiencia de la fotografía participativa, con la pretensión de abordar el fenómeno desde orillas diversas que permitan de-construir la categoría de discapacidad visual, reconociendo a la persona en su multidimensionalidad. Este estudio reconoce que la discapacidad visual no debe ser considerada un obstáculo a la creación de imágenes fotográficas, pues las personas con esta condición perciben la realidad a través de otros sentidos y a partir de la asociación de ellos, crear imágenes mentales de sus percepciones de la realidad y representarlas a través de una fotografía. Las imágenes diseñadas y producidas por los participantes con discapacidad visual evidenciaron que la fotografía no es solamente una actividad limitada a personas videntes, sino que si se aplica la técnica adecuada y se acude a la percepción que proviene de los demás sentidos, esta actividad podrá ser ejecutada exitosamente.

Establishment of Reference Values of Gamma-Glutamyl-Transferase and Plasma Aminotransferases in Young Congolese
Authors: Ngokana Linel Darrel , Koumou Fylla Onanga , Loukanou Mbouaka Landry Aymar
Published: September 2021

Objectives: Our goal was to contribute to the production of reference values ​​of plasma or serum biochemical markers by determining the reference values ​​of gamma-glutamyltransferase (GGT), aspartate aminotransferase (ASAT) and alanine aminotransferase (ALAT) in young Congolese presumed to be healthy.
Methods: 250 young Congolese presumed to be healthy (125 boys and 125 girls) aged 15 to 25 participated in the study. They were selected according to anamnestic and clinico-biological criteria. Samples were taken on a tube containing EDTA and the resulting plasma was stored at -20 ° C. The KENZA MAX spectrophotometer was used to analyze GGT, ASAT and ALAT. The median and the 2.5-97.5 percentiles were used to set the reference limits for each enzyme. The benchmarks determined were compared with those reported by other Africans, Europeans, Indians and Americans.
Results: The established reference values ​​were: GGT 12.15-61.85 IU/L for boys and 7-51.95 IU / l for girls (p˂0.0001); ASAT 21.60-94.85 IU/L for boys and 17-84.85 IU/L for girls (p = 0.0003); ALAT 8.30-74.40 IU/L for boys and 8-53.85 IU/L for girls (p˂0.0001). In addition, the comparison between our values ​​and those of other populations showed significant differences.
Conclusion: Our results underline the importance of establishing reference values ​​for plasma enzymes specific to the Congolese population. The use of the values ​​established in the ’other populations could induce errors of judgment by excess or by default.

Published: September 2021

Background: Significant empirical surveys have been made to investigate sociodemographic factors contributing to Risky Sexual Behaviours among young people. However, there are concerns regarding what influences Risky Sexual Behaviours. The purpose of the study is to examine the relationship between the sociodemographic variables and Risky Sexual Behaviours among undergraduate students in tertiary institutions. Methods: A cross-sectional study was conducted among undergraduate students at two tertiary institutions in Rivers State, Nigeria to investigate the relationship between sociodemographic variables and Risky Sexual Behaviours. Undergraduate students in years one and two from departments of Nursing Science and Medicine and Surgery in PAMO University of Medical Sciences and University of Port Harcourt, College of Medicine were recruited for the study. Two hundred and eighty (280) undergraduate students were randomly selected from a total of 491 as participants in the study. Descriptive and inferential analysis of data using SPSS version 20 was done. Results: Data showed that 60% of the respondents were from the University of Port Harcourt, while 40% were from PAMO University of Medical Sciences. The majority of the students (78.9%) were between 16 -20years, while only 0.7% of the students were ≥31years. Findings revealed that there is no significant relationship between respondents’ sociodemographic variables and awareness of, attitude to risky sexual behaviour. It was found that only gender and age significantly influence practices with an R2 of 0.22. Conclusion: Risky sexual behaviour among young people is significantly associated with age and gender.
Is it really safe to evaluate symptomatic extensor carpi ulnaris tendon instability by magnetic resonance imaging (MRI)?
Authors: Öztürk Tahir , Burtaç Eren Mehmet
Published: September 2021

The extensor carpi ulnaris (ECU) tendon is in the sixth extensor compartment of the wrist and is isolated from other tendons by a different sheath. Extensor carpi ulnaris pathologies are characterized by pain locally localized to the wrist ulnar side. Outpatient records and wrist MRI (magnetic resonance imaging) tests were retrospectively scanned between January 2018 and July 2019. By examining the anamnesis and examination notes of the patients in the outpatient clinic records, patients with wrist ulnar side pain, pain or sensitivity on the ulnar styloid and provocation test (synergy) were assigned to the first study group (Group 1).The second study group was composed of patients who underwent wrist MR for the diagnosis or differential diagnosis of a synovial cyst around the wrist, without ulnar side pain (Group 2).While evaluating MR images in the axial plane, the depth and width of the ulnar groove, thickness of the ECU tendon were measured. The position of the ECU tendon relative to the ulnar groove and the forearm rotation during the shooting were recorded.105 cases evaluated, there were 41 cases in the symptomatic subgroup and 64 cases in the asymptomatic subgroup. Among all patients, the mean patient age was 38.05.In the evaluation according to whether cases were symptomatic or not, there was no significant relationship between being symptomatic and the degree of instability and MR withdrawal position.

Our study suggests that ECU instability in MR is not a specific condition, and detection of MR in instability may not be associated with a patient’s symptoms.
Acute femoral fracture does not compromise the outcome of total hip arthroplasty : 5 year results from a single center cohort study in 2,782 patients

Published: September 2021

National arthroplasty registries reveal a higher risk of revision for periprosthetic fracture and dislocation after total hip arthroplasty (THA) in patients with a femoral neck fracture compared to those with osteoarthritis (OA). Since these registries may con- tain confounding factors, we conducted a single center cohort study comparing survival and reason for failure between THA for an acute femoral neck fracture and OA using the same hip prosthesis after a minimum follow-up of 2 years.

We retrospectively analyzed 2782 patients who had undergone THA with an Accolade TMZF stem and a Trident cup between March 2009 and September 2014. Primary diagnosis before THA was osteoarthritis (OA group : n=2610) or acute femoral fracture (Fracture group : n=172). Patients in both groups were operated on by the same hip surgeons. Effect of diagnosis on THA survival was analyzed using Cox-regression analysis. Chi-square tests were used to illustrate the different reasons for revision between the groups.

Mean follow-up was 4.6 years (2-7.6). A total of 100 revisions were performed. The revision risk was comparable between the OA and Fracture group (HR=1.04, 95% CI :0.46-2.39). No differences were found between the OA and Fracture group with respect to the occurrence of periprosthetic fractures (0.8% vs. 0.6%, p=0.71) and revisions for dislocation (0.6% vs. 1.2%, p=0.38).

We found no difference in outcome or reason for revision between THA for OA or femoral neck frac- ture. Using an implant with a proven ODEP rating and having experienced hip surgeons carry out the procedures may be more important than the primary diagnosis.
Knee mega-prosthesis in the management of complex knee fracture of the elderly : a case series and review of the literature
Authors: Beckers Gautier , Mazy David , Tollet Philippe , Van Nieuwenhove Olivier
Published: September 2021

The management of complicated distal femur fractures (DFF) of the elderly continues to pose a challenge. Knee mega-prosthesis are mostly used for Total knee arthroplasty revision and tumor resection surgery but they can be used for the treatment of complex knee fractures. The purpose of the present study is to examine the short- to mid- term outcomes of their use for complex DFF of the elderly. We retrospectively identified 4 patients with DFF AO33C3 on osteoporotic bone treated by total knee arthroplasty from September 2015 to October 2019. The average age at the time of the surgery was 79,5 years (range, 69 to 95 years). All patients were females and underwent a total knee replacement by one senior surgeon, with the OSS TM Orthopaedic Salvage System (Zimmer Biomet, Warsaw, Indiana, USA). Outcome measures included clinical outcome scores, radiological analyses, reoperation rate and complications.

At an average follow-up of 2,3 years (range, 0,6 to 4,2 years), the average Western Ontario and McMaster Universities Osteoarthritis index (WOMAC) was 17,25 (range, 7 to 37), the average Oxford knee score was 35,25 (range, 25 to 41) and the average pain Numerical Rating Scale (NRS) was 0,5 (range, 0 to 1). 3 Patients had postoperative anemia but no implant related complications has been reported.

Complex DFF of the elderly treated with mega knee arthroplasty exhibit good clinical outcomes scores. The patients should be selected carefully as the complication rate found in the literature remains high.
Investigation of the relationship between trochlear morphology and medial patellar cartilage defect using magnetic resonance imaging
Authors: Duran Semra , Gunaydin Elif
Published: September 2021

The aim of this study was to evaluate trochlear morphology in patients with medial patellar cartilage defects via magnetic resonance imaging (MRI).

Three hundred patients who were diagnosed with grade 2, 3 and 4 medial patellar cartilage defect using MRI according to the International Cartilage Repair Society Classification System and 100 control subjects were evaluated. Trochlear morphology was evaluated based on lateral trochlear inclination (LTI), medial trochlear inclination (MTI), sulcus angle( SA), femoral lateral and medial condyle symmetry, trochlear facet asymmetry, and trochlear width on the axial MR images.

The mean SA was significantly higher in the medial patellar cartilage defect group compared to the control group (p<.05). The LTI and MTI of the cartilage defect group were significantly lower than those of the control group (p<.05). With the decreasing LTI and MTI, there was an increase in medial patellar cartilage loss. LTI (r=-0.46) and MTI (r=-0.53) were moderately correlated with SA. There was no significant differences in femoral lateral and medial condyle symmetry, trochlear facet asymmetry, and trochlear width between groups with and without medial patellar cartilge defect (p > .05).

A flattened medial trochlea is a risk factor for cartilage structural damage of the medial patellofemoral joint, and it plays a role in the development of a defect in the medial patellar cartilage. The medial patellar cartilage defect is associated with the flattened lateral trochlea.

Patients with ACL tears with ALL injury have more clinical complaints (instability, feeling of the pop on the knee or knee sliding). patients have ALL injury with partial ACL tears, It is unclear whether the choice of treatment will be conservative or surgical.

This study aimed to determine the effect of anterolateral ligament (ALL) status, whether intact or ruptured, on the choice of conservative or surgical treatment in patients with partial anterior cruciate ligament (ACL) tears.

Between 2015 and 2019, patients with suspected partial ACL tears were identified on both physical examination and MR imaging. 122 patients who had partial ACL tears and also status of patient’s ALL could be evaluated by radiologist were included in the study, retrospectively.

Sixty-two patients who underwent ACL reconstruction were determined as group 1, and 60 patients who did not undergo ACL reconstruction were defined as group 2. In patients with partial ACL rupture with or without ACL reconstruction, it was evaluated whether a ruptured or non- ruptured ALL was effective in this decision of conservative or surgically.

The MRIs of patients with partial ACL tears were evaluated by a radiologist and it was concluded that the ALLs of 50 patients were ruptured, and 72 were intact. The ALLs of 36 patients in group 1 were ruptured, and 26 patients were intact. Fourteen patients in group 2 had ruptured ALLs, 46 patient’s ALLs were intact. Seventy-two percent of the patients with partial ACL tears who had ruptured ALLs in MRI underwent ACL reconstruction.

It was found that ACL reconstruction was performed more frequently in patients with partial ACL tears with ALL rupture. Therefore, we believe that preoperative evaluations of ALLs using MRI in patients with partial ACL tears are essential for surgical planning.

Lồng ruột hiếm gặp ở trẻ sơ sinh, đặc biệt đối với trẻ sinh non cực kỳ hiếm gặp và thường bị nhầm lẫn với viêm ruột hoại tử hoặc xoắn ruột do có các triệu chứng lâm sàng tương đồng dẫn đến việc chẩn đoán bệnh thường chậm trễ. Chúng tôi báo cáo một trường hợp trẻ sơ sinh đủ tháng vào viện do bụng chướng, nôn ra máu và đi ngoài phân máu. Trước phẫu thuật trẻ được chẩn đoán xoắn ruột, sau khi mổ phát hiện nguyên nhân gây ra tình trạng trên do lồng ruột. Do đó, lồng ruột dù hiếm gặp nhưng cần được xem xét để chẩn đoán đối với những trường hợp trẻ sơ sinh có các triệu chứng tiêu hóa.
Fear of hypoglycemia in Italian mothers of children with type 1 diabetes: the mediating role of resilience
Authors: Cardinali Paola , Rapetti Elisa , Migliorini Laura
Published: September 2021

Objective

Fear of hypoglycemia for children with diabetes influences parental life and could increase parental stress. The present study aimed to explore the association between resilience, the self-perception of the parental role, and fear of hypoglycemia in mothers of children with type I diabetes (T1DM).

Methods

Ninety mothers (mean age: 44.20 years) of children with a T1DM diagnosis (mean age: 11.48 years) were recruited from an association for parents and completed an online self-report questionnaire packet that includes: Fear of Hypoglycemia Survey, Self-Perception of the Parental Role and Resilience Scale for Adults. Participants were recruited in 2017. Data collection lasted 10 months. Data analysis was performed using the SPSS statistical package, version 22, and the PROCESS macro program by Hayes.

Results

The analysis of the mediation model shows that resilience assumes a mediational role in the relationships between the parental role and preoccupation with hypoglycemia. In particular, the mother’s perceived competence and role balance can influence the development and increase of the mother’s resilience, which in turn can allow a decrease in the mother’s worry about the possible hypoglycemic episode of her child.

Conclusion

The findings suggest that resilience is a significant topic to focus on in interventions designed to increase the self-perception of the parental role and reduce fear of hypoglycemia in mothers
How partnerships shaped the Dane CARES Farm-to-Food Bank program
Authors: Guffey Calkins Jessica , Mance Claire
Published: September 2021

The COVID-19 pandemic forced Wisconsin’s food systems institutions into rapid innovation as they responded to rising community food insecurity. With support from the Dane County Executive’s office, federal relief funding eased previously onerous barriers to allow Dane County’s largest food bank to implement a unique local purchasing program: Dane CARES. The program sought to support Dane County producers experiencing reductions in market opportunities, while feeding the rising number of Dane County families experiencing food hardship. Drawing on existing food and agriculture partner­ships, Extension Dane County staff connected partners to assist with project expedition and docu­mented partners’ efforts through a series of semistructured interviews. The program achieved its two primary goals of replacing lost markets for local farmers and facilitating increased food distribution to communities in need. To elevate this multisector collaboration and inspire more great work like Dane CARES, we outline the evidence of program value to farmers’ livelihoods, demonstrate the growth of partner networks to support institutional purchasing of local food, and offer recommendations to improve future program iterations.
From seed to social agency
Authors: Klinke Chelsea , Samar Gertrude
Published: September 2021

Food studies is an emerging and interdisciplinary field that has produced abundant theoretical, analytical, and conceptual insights into contemporary agro-food system dynamics. However, space still exists for the convergence of classroom-based food pedagogy and transformative community work to promote social justice frameworks. While calling for a paradigm shift within educational systems, we ask, how can community-based experiential engagement in post-secondary food pedagogy enhance student learning, bridge academic-public divides, and foster transformative social change? Drawing from our experiences farming in Calgary, we argue that activist food studies employed with a learner-centered, place-based teaching approach centering Indigenous Knowledge Systems can support local food networks and build community within and beyond academia. We present strategies for bridging the academic-public divide through a participatory approach and activist scholarship that directly engages with sustainable urban and agrarian development. Complementing course-based theory and literature with applied methodologies that build the technical and leadership capacity of students will enhance student learning, build stronger community ties, and produce meaningful work that connects the local to the global. Furthermore, we will reflect upon our approach, identify potential benefits to students who engage in food studies, and offer recommendations for best practices in food pedagogy that will support social change.
Reflections on the North Central Community Gardens Branch Out Project
Authors: Krajewski Maegan
Published: September 2021

The North Central Community Gardens, an urban agriculture initiative of the North Central Community Association in Regina, Saskatchewan, Canada, introduced the Branch Out Project in the summer of 2020. The project’s purpose was to expand the North Central Community Gardens, which already consisted of three locations, onto additional schoolyard and backyard land. Despite—or perhaps because of—the COVID-19 pandemic, the first season of the project resulted in the construction of eight new gardens and has positively impacted food access, community engagement, and knowledge development and exchange. The goals of this commentary are two-fold: (1) to provide insight into the process of community garden expansion, with the hopes of benefiting other practitioners; and (2) to contribute to an understanding of the possibilities, challenges, and impacts of community gardens in general, and community garden expansion in particular, as a counter-neoliberal food sovereignty practice.

The right to information is an important instrument for a control of public authority in any democratic state. Ocasionally, however, there may be a conflict between this right and the  right to privacy. In this context, the Czech Supreme Administrative Court was tasked with  solving the question of whether information on the salaries of employees who are paid from  public funds can be published.
