The aim of this paper is to present the current state of research on gait parameters in people after unilateral amputation above the knee joint and to compare these gait parameters with those of healthy people. The relevant literature does not include any similar publications. Modern prostheses do not eliminate the asymmetry of gait, although its consequences are diminished. An above-knee amputation leads to significant differences in ground reaction force parameters (GRF) between the sound and amputated limb. The amputated limb is charac­te­rised by lower values of vertical and antero-posterior GRF parameters in comparison with the intact limb. Moreover, during the contact of the heel with the ground, the degree of hip joint flexion of the amputated limb decreases in comparison with the intact limb. Other symptoms of asymmetry between the limbs include asymmetry of pelvic movement in the transverse plane and of the range of movement in the ankle joint. De­creased muscle torque on the hip joint in the amputated limb additionally increases asymmetry of biome­chanical gait parameters after unilateral transfemoral amputation.

This research is concentrated in the increasing of education issue studies using the management of potential data on Websites for Communicating Research in the field of Education. This research relates with several web sites, i.e: https://puspendik.kemdikbud.go.id/hasil-un/, and https://dapo.dikdasmen.kemdikbud.go.id/sekolah/ Furthermore, this research is also purposed in order to elucidate the potentials and challenges of internet data for education to demonstrate a selection of relevant literature so that a wide spectrum of topics can be reached. A part of this data represents a large and increasing part of everyday life which sometimes could not be measured. The data used are a timely data which are potentially following a factual process, moreover they typically involve large numbers of observations, and they allow for flexible conceptual forms and experimental settings. In this paper, the data that are gained will be managed such that some academic articles are produced. Some data at the Internet had successfully been applied to a very wide range of detecting education issues (e.g. spatial analysis for relation a number of male and female students and score of mathematics and foreign languages test), we review the current literature attempts to incorporate the Internet data into the mainstream of scholarly empirical research in our research and guide the reader through this Special Issue. We provide some insights and a brief overview of the current state of research.

Abstract Background Above-knee amputations (AKAs) contribute to gait asymmetry. The level of asymmetry is affected by the type of knee prosthetic module. There is limited evidence suggesting that more technically advanced solutions (microprocessor modules; MicPK) are superior to less advanced ones (mechanical modules; MechPK). The study aimed to evaluate the variable range of hip and pelvic joint movements during gait and look for differentiating areas with an increased level of asymmetry of the gait cycle in individuals who underwent an AKA and are equipped with MicPK or MechPK. Methods Twenty-eight individuals participated in the study; 14 were assigned to a study group of individuals who underwent a unilateral AKA, and the other 14 were healthy participants as a control group. The movement task was recorded using the optoelectronic SMART-E system following the standard Davis protocol (the Newington model). A new method of quantifying gait symmetry using the symmetry function (SF) is proposed. SF is an integral measure of absolute differences in time-standardized signals between sides throughout the whole cycle of motion variability. Results In the frontal plane, there were significant differences between groups in the asymmetry of the range of movement in the hip joint of the intact limb. In the middle of the support phase, the intact limb was more adducted in individuals with MicPK and less abducted in people with MechPK (differences in mean 180%, p < 0.000; max 63%, p < 0.000; min 65%, p < 0.000). In the sagittal plane, the range of asymmetry of the flexion and thigh extension of the intact limb was similar to and only slightly different from the physiological gait. In the transverse plane, higher asymmetry values were noted for individuals with MicPK. In the final stage of the swing phase, the thigh was more rotated both externally and internally. The size of the asymmetry, when compared to gait of healthy individuals, reached 50% (differences in mean 115%, p < 0.232; max 62% p < 0.26; min 50, p < 0.154). Conclusions In the study group, the assessed ranges of pelvic and thigh movement in the hip joint differed only in the frontal plane. Individuals who underwent a unilateral above-knee amputation may gain less from using MicPK than anticipated.

Purpose: This paper is a thematic literature review to examine the current state of research about Culturally Responsive Pedagogy in mathematics. The main themes are students’ perception, teacher education for pre-service teacher and professional development for teachers. Research methods/ approach: Literature was collected from Eric, which is a research engine of the education field. Also, Google Scholar is used to find articles of major scholars introduced by Dr. Rich Milner, who is the instructor of this course. Findings: Students faced microaggressions in mathematics class, which discouraged them to learn mathematics. The effect of teacher education was inconsistent in terms of the awareness of culturally responsive pedagogy and lesson plans. Research of professional development mentioned that mathematics was cultural. Implications for research and practice: It is more interesting to conduct long term or follow-up research to find the teacher’s practice after a taking professional development program. Also, it is critical to expand research scope besides African American and Latino students. Finally, evidence-based research is needed to change the political situation. Keywords: culturally responsive teaching, mathematics, teacher education, professional development, student’s perception

Abstract Purpose of Review Augmented reality (AR) is becoming increasingly popular in modern-day medicine. Computer-driven tools are progressively integrated into clinical and surgical procedures. The purpose of this review was to provide a comprehensive overview of the current technology and its challenges based on recent literature mainly focusing on clinical, cadaver, and innovative sawbone studies in the field of orthopedic surgery. The most relevant literature was selected according to clinical and innovational relevance and is summarized. Recent Findings Augmented reality applications in orthopedic surgery are increasingly reported. In this review, we summarize basic principles of AR including data preparation, visualization, and registration/tracking and present recently published clinical applications in the area of spine, osteotomies, arthroplasty, trauma, and orthopedic oncology. Higher accuracy in surgical execution, reduction of radiation exposure, and decreased surgery time are major findings presented in the literature. Summary In light of the tremendous progress of technological developments in modern-day medicine and emerging numbers of research groups working on the implementation of AR in routine clinical procedures, we expect the AR technology soon to be implemented as standard devices in orthopedic surgery.

Olfaction, the sense of smell, is characterized by a notable age-dependency such that aging individuals are more likely to have poor olfactory abilities. These impairments are considered to be mostly irreversible and as having potentially profound effects on quality of life and food behavior, as well as constituting warning signs of mortality, cognitive dysfunction, and dementia. Here, we review the current state of research on aging and olfaction, focusing on five topics which we regard to be of particular relevance for the field: nutrition and health, cognition and dementia, mortality, environment and genetics, and training-based enhancement. Under each of these headlines, we provide a state-of-the-art overview and discuss gaps in our knowledge which might be filled by further research. Understanding how olfactory abilities are diminished in aging, and how they may be alleviated or recovered, involves a set of challenging tasks for researchers in the years to come.

Technical And Professional Communication

Fierce competition has made innovation increasingly necessary for business success, and this has increased the importance of user-based innovation strategies like design thinking (DT). While many studies in technical and professional communication (TPC) have explored how DT can be used pedagogically, no studies have done this through investigating how DT is used as a workplace composing process. This study does exactly that. First, it presents the current state of research on pedagogical uses of DT in TPC, and then it builds upon those suggestions with an empirical study that chronicles on how two web design firms use DT to make websites. My main suggestion is to teach DT as a recursive process that allows students transcend potentially incorrect assumptions built into design tasks through gathering data not only from users, but from clients as well.
