Authors: Geelhoed Sandra , Trowbridge Hayley , Henderson Sarah , Wallace-Thompson Lauren
Published: January 2022

Storytelling is a powerful instrument for system change. Telling stories of lived experience, listening to them, and sharing them contributes to a culture of trust based on dignity, mutual respect and shared values. In this paper we draw attention to public service innovation and co-creation with the people the service is meant for. In the past years, public service innovation was result-and output driven, targeting technological and managerial innovation. Stories of service users revealed the unintended negative consequences of such innovation policies and opened new perspectives for conversations of change based on shared values leading to innovations based on human development and dignity.

Authors: Țecu Cristian , Pînzariu Sorin
Published: January 2022

Training using different simulation systems has become a necessity for the military organizations over the past decades. As the operational environment is constantly changing and the technologies are evolving, simulation systems have also developed. Depending on the domain and branch the simulation training is used for, there have been serious challenges in adapting the systems to the current technological era. Moreover, the emerging technology had a great impact on the military training using simulation systems and has brought an advantage to this domain. Consequently, individual training, collective training, special skills training using simulation systems have been some of the aspects that have been consistently changed and improved over the past years. Technologies such as virtual reality (VR), augmented reality (AR), artificial intelligence (AI), soldier simulators and the initiative of converging constructive and virtual simulation through cloud technologies are some of the major sciences that have been starting to be developed, tested and used for military training purposes. Nevertheless, technological development and operational changes need to also face the challenges of interoperability of the simulation systems that would eventually need to be connected in the inevitable context of integrated, distributed, joint or multinational events.

Published: January 2022

Vulnerability is a prevalent problem affecting both personal and organizational security. Our study represents a comprehensive assessment of a particular social security network, which seeks to examine the academic environment and to expose some improvement initiatives. The purpose is to develop a multi-element suitability analysis by overlaying existing referenced social circumstances to a PESTLE analysis. Exploring some external EDTs factors makes, it clear that new treatment instruments are being considered for the balanced security approach of an organizational culture. The research findings indicate that the approach serves as a great management tool for the heading board, highlighting its importance for regaining control over the aggressive elements that threaten the collective security. Further, our efforts adapt the excellence of the academic community to social value system by involving as a central element the corporate social responsibility. The military sector develops public and private partnerships, whereas academia and civil society develop new technologies to strengthen the military industrial and technological base.

Authors: Warpechowski Marcin , Warpechowski Jędrzej Jan
Published: January 2022

The development of health sciences along with the continuous technological progress contribute to the emergence of web applications. There exist many applications supporting the work of doctors, whereas the market definitely lacks solutions supporting the work of nurses. This is particularly evident in long-term geriatric home care, in which the nursing specialization is developing rapidly. Care of elderly patients requires the nurse to collect medical documents from each visit. Considering the large number of diseases affecting elderly people and the number of required visits – which should exceed 4 a week – a decision was made to develop an Internet application supporting the work of nurses in long-term geriatric care. The application facilitates the process of geriatric patient description in order to eliminate the need for filling in paper medical records. This study presents the method of developing an Internet application supporting the work of nurses in long-term geriatric care. The software was developed based on an analysis of conclusions from a social study carried out in a group of 42 nurses providing geriatric long-term home medical care services in the district of Białystok, Poland. The aim of the study was to determine the features, functionality, and declarative interest in using the software. Conclusions from the analysis indicated that the attempt to develop the application had been justified. Moreover, conclusions from the social survey formed the basis for formulating the design assumptions. The web application was developed in the following technologies: HTML 5, CSS3, JavaScript, PHP 7, and MySQL. First, a prototype of the solution was tested in a XAMPP environment. After successful tests, the app was tested in a nursing practice. The obtained test results raise high hopes for potential commercialization of the application.
Cooperation Between a Doctor and a Podiatrist to Improve the Quality of Life of Patients with Ingrown Toenails
Authors: Trochanowski Tomasz , Baum Ewa , Żaba Ryszard
Published: January 2022

Cooperation between doctors of various specialties and other medical specialists is the standard of care in the treatment of patients. Due to the variety of diseases and the dynamic development of medicine in general, it is difficult to be an expert in every field and know all the recommended treatments. An example of such cooperation is the joint treatment of patients with the problem of ingrown toenails. The article contains an analysis of patients who received treatment in a doctor’s office in cooperation with podiatrists. A conservative approach towards the treatment of this condition sees the patient being initially diagnosed and treated by a podiatrist and then later, if necessary, being referred to a doctor for surgical treatment. The exchange of experiences and information on patients treated by interdisciplinary teams allows doctors and podiatrists to find the best possible treatment and improve the quality of life of patients. The follow-up of patients after surgery can be performed later in podiatry offices. Owing to modern electronic communication, it is possible for a doctor to constantly monitor the patient’s condition without the need for direct visits to the doctor’s office.

Published: January 2022

The objective of this research is to investigate the implementation of Contextual Teaching and Learning (CTL) to improve students’ speaking skills in the aspects of accuracy, clarity, and fluency. This research employed a quantitative method in nature. A pre-experimental design with pre-test and post-test was used. The population of this research was all second-year students. The sample of this research was one of the second-year classes chosen by using the purposive sampling technique. The instrument used in this research was a speaking test: pre-test and post-test. The data collected were analyzed statistically. The results showed that the implementation of contextual teaching and learning (CTL) improved students’ speaking skills in terms of accuracy, clarity, and fluency. The result of Wilcoxon showed the value of Asymp. Sig (2-tailed) for accuracy, clarity, and fluency is 0.000 which means that the resulting test is less than the minimum requirements of the statistics range (0.05). Therefore, the use of CTL in teaching and learning speaking is very beneficial for students to improve their speaking skills. Thus, the hypothesis of this research was accepted. There is a significant improvement in students’ speaking skills after they were taught by using CTL.

Authors: Mareza Putri , Gani Sofyan A. , Samad Iskandar Abdul
Published: January 2022

This case study is aimed at finding out the types of classroom communication strategies employed by English department lecturers during their teaching. In this study, three lecturers participated (HQ, RR, and SW in pseudonyms). They were lecturers for academic English, critical speaking, and advanced reading classes. The instruments of this study were videotapes, observation guides, field notes, and interview guides. After the data collection process, the data were analyzed using coding analysis and interactive analysis. The results showed that the most employed direct strategies were circumlocution and code-switching. HQ used circumlocution 54 times and code-switching 51 times; RR used circumlocution 21 times and code-switching 32 times. The major use of indirect strategies was comprehension check, which was used 47 times by RR, 28 times by HQ, and 9 times by SW. Last, for the interactional strategy, filler was the most used strategy. RR used it 19 times, HQ used it 46 times, and SW used it 26 times. It is suggested that lecturers are expected to balance these three strategies to maintain good teacher-student communication. However, for adult learners (college students), it is found that lecturers mostly use circumlocution during the lecture.

Introduction: Deep Vein Thrombosis (DVT) after varicose vein surgery is well recognized. Less well documented is Endovenous Heat-Induced Thrombosis (EHIT), thrombus extension into a deep vein after superficial venous thermo ablation. There is no current agreement on the routine use of thromboprophylaxis in patients undergoing varicose vein surgery. more data on the incidence of VTE, and the need for postoperative thromboprophylaxis are necessary to formulate evidence-based clinical guidelines. Aim of the study: Comparison of the use of Caprini's Saphenous Ablation Scores versus Standard Caprini’s Score for the prophylaxis of VTE in EVLA. Patients & Methods: 60 patients admitted to Royal Vascular Center, Alexandria - Egypt. From Jan. 1st, 2021, to June 30th 2021 divided in 3 groups. - Group A) Treated by ablation of Great saphenous vein and received VTE prophylaxis according to Caprini’s Saphenous Ablation Scores Fig 1-A & B -Group B) Treated by ablation of Great saphenous vein and received VTE prophylaxis according to Standard Caprini’s Risk Assessment Score for VTE Fig 2-A&B - C) Treated by ablation of Great saphenous vein without VTE prophylaxis Ablation was done using radial 1480 YAG laser fibers and Post-operative Duplex was done one day, 3 month and one-year. Results: Age: 35.6+0.2, 34.3+0.5 and 37.6+0.09 years in the 3 groups M/F: 6/14, 8/12 and 7/13. In group A) all patients showed absent reflux post operatively and in all follow up visits. Duplex examination revealed significant reflux in the great saphenous veins in all patients and ranged from 0.7:0.9 Sec. and mean duration 0.7+0.09 Sec. Vein diameter ranged from (0.6: 0.9,X+0.76 CM.) in group A), (0.6: 0.8,X+0.7 CM.) in group B) , (0.5: 0.8,X+0.65 CM.) in group C) According to Caprini’s saphenous score 14 patients 70% were classified as low risk, 4 patients 20% were of moderate risk and 2 patients 10% of high-risk in Group A, while applying standard Caprini’s Score in group B patients revealed: 6 patients 30% were of moderate risk and 14 patients 70% of high risk in Group B ) . 3 patients developed superficial thrombophlebitis 15% and one patient 5% developed left calf DVT in Group C, while no VTE events were shown in both A&B Groups Significant drop in CVSS in patients in the three groups. Conclusion: Risk assessment of patients undergoing varicose veins ablation should be done and applying Caprini’s saphenous score as a better alternative to Standard Caprini’s score for VTE prophylaxis and is considered a safe and cost-effective tool in VTE prevention in these patients.

Introduction: Abdominal pregnancy is a rare form of ectopic pregnancy with very high feto-maternal morbidity and mortality. Diagnosis and management can pose difficulties in low-resource centres. High index of suspicion is vital in making a prompt diagnosis. Case Presentation: A 23year old, gravida 2, para 1, who presented with a two-day history of severe abdominal pain was referred from a satellite clinic. Abdominal ultrasound scan revealed a live 18week 5day intra-abdominal pregnancy. Emergency laparotomy showed an intact gestational sac at the superior aspect of the uterus with massive hemoperitoneum. The placenta was attached to the right ovary, omentum, and fimbriae of the right fallopian tube. Conclusion: Abdominal pregnancy is a rare occurrence and requires a high index of suspicion for prompt diagnosis. Massive hemoperitoneum can be life threatening and prompt surgical intervention is key in saving the life of the mother.

Delayed allergic skin reactions to vaccines
Authors: Aquino Marcella R. , Bingemann Theresa A. , Nanda Anil , Maples Kelly M.
Published: January 2022

Background: Recent advances in vaccination against the severe acute respiratory syndrome coronavirus 2 pandemic have brought allergists and dermatologists to the forefront because both immediate and delayed hypersensitivity reactions have been reported. Objective:
This literature review focused on delayed reactions to vaccines, including possible causative agents and practical information on how to diagnose, evaluate with patch testing, and manage subsequent dose administration. Methods: Currently published reviews and case reports
in PubMed, along with data on vaccines from the Centers for Disease Control and Prevention web site. Relevant case reports and reviews that focused on delayed reactions to vaccines were selected. Results: Most delayed hypersensitivity reactions to vaccines include cutaneous
manifestations, which vary from local persistent pruritic nodules to systemic rashes. The onset is usually within a few days but can be delayed by weeks. Multiple excipients have been identified that have been implicated in delayed vaccine reactions, including thimerosal, formaldehyde, aluminum,
antibiotics, and gelatin. Treatment with antihistamines, topical corticosteroids, or systemic corticosteroids alleviates symptoms in most patients. Such reactions are generally not contraindications to future vaccination. However, for more-severe reactions, patch testing for causative agents
can be used to aid in diagnosis and approach further vaccination. Conclusion: Delayed-type hypersensitivity reactions to vaccines are not uncommon. If needed, patch testing can be used to confirm agents, including antibiotics, formaldehyde, thimerosal, and aluminum. In
most cases, delayed cutaneous reactions are not contraindications to further vaccine administration.

Authors: Magen Eli , Yakov Avi , Green Ilan , Israel Ariel , Vinker Shlomo , Merzon Eugene
Published: January 2022

Background: The factors that trigger and exacerbate chronic spontaneous urticaria (CSU) are well known, but it is not unclear whether messenger RNA (mRNA) vaccination against severe acute respiratory syndrome coronavirus 2 can trigger new cases of CSU or a relapse of CSU
after long-term remission. Objective: To study the clinical cases of patients with new-onset CSU and CSU in remission who relapsed within 3 months after BNT162b2 mRNA vaccination. Methods: All patients with a CSU diagnosis within 12 weeks of BNT162b2
mRNA vaccination were retrospectively identified and included in the new-onset CSU and the relapsed CSU groups. The first control group (CSU control group) retrospectively consisted of patients diagnosed with CSU in complete clinical remission for ≥ 6 months, with no CSU relapse after vaccination.
The second control group (healthy control group) consisted of subjects who were fully vaccinated and without CSU, matched 1:2 for age and sex with patients with CSU. Results: Twenty-seven patients were included in the relapsed CSU group, 32 patients in the new-onset CSU
group, 179 patients in the CSU control group, and 476 subjects in the healthy control group. The relapsed CSU and new-onset CSU groups had more allergic comorbidities overall (19 [70.4%] and 13 [40.6%], respectively) than the CSU control group and the healthy control group (50 [27.9%] and
110 [23.1%], respectively; p < 0.001). Multiple logistic regression analysis showed that a positive autologous serum skin test result, overall allergic comorbidities, and basopenia were positively associated with the probability of CSU relapse within 3 months after BNT162b2 mRNA vaccination
(odds ratio [OR] 5.54 [95% confidence interval {CI}, 2.36‐13.02], p < 0.001); OR 6.13 [95% CI, 2.52‐14.89], p = 0.001; and OR 2.81 [95% CI, 1.17‐6.72, p = 0.020, respectively). Conclusion: It is possible that BNT162b2 mRNA vaccination serves as a
provoking and/or relapsing factor of CSU in individuals with allergic diseases and/or predisposed autoimmunity.

Carbon Dioxide (CO2) Emissions Due to Motor Vehicle Movements in Pekanbaru City, Indonesia
Authors: Sari Erza Guspita , Sofwan Muhammad
Published: January 2022

Land use has a very close relationship with transportation. Transportation is formed as a result of the interaction between land use and its support system. Good land use supported by good infrastructure will result in good movement as well. Accessibility is one of the supporting factors for good interaction between transportation and land use—the better the land use conditions in an area, the greater the movement in that area. However, the interaction between land use and transportation can cause one of the problems: the increase in carbon dioxide emissions due to the more significant movement of motorized vehicles. Motor vehicles are the most significant contributor to carbon dioxide (CO2) emissions in the world. The further the route traveled by motorized vehicles, the more carbon dioxide (CO2) emissions will increase. This study aims to analyze the average total emission of carbon dioxide (CO2) resulting from transportation activities in Pekanbaru City into two parts, namely: (1) Based on Travel Time (2) Based on the type of vehicle. Vehicle Kilometers of Travel (VKT) and Emission Factors are the primary data in calculating Carbon Dioxide (CO2) Emissions. The research area consists of 12 zones involving 1,342 households in Pekanbaru City. Based on travel time, 52% of community motorized vehicle movement activities are carried out in the morning. Private cars contribute 65% of carbon dioxide (CO2) emissions in Pekanbaru City based on the type of vehicle. This study found that a high number of motorized vehicles cannot be used as a benchmark that the resulting emissions will also be high. However, the emission of carbon dioxide (CO2) depends on the fuel consumption of each vehicle. The higher the fuel consumption, the higher the amount of carbon dioxide (CO2) emissions released by motorized vehicles.
Street Level Flood Monitoring and Warning System, a conceptual model using IoT: A Case of Surat City
Authors: Patel Anant , Yadav Sanjay
Published: January 2022

Most of the natural disasters are unpredictable, but the most frequent occurring catastrophic event over the globe is flood. Developing countries are severely affected by the floods because of the high frequencies of floods. The developing countries do not have good forecasting system compared to the developed country. The metro cities are also settled near the coast or river bank which are the most vulnerable places to floods. This study proposes plan for street level flood monitoring and warning system for the Surat city, India. Waterlogging happens in the low lying area of the Surat city due to heavy storm and heavy releases from the Ukai dam. The high releases from upstream Ukai dam and heavy rainfall resulted into flooding in the low lying area of the Surat city. This research proposed a wireless water level sensor network system for the street water level flood monitoring. The system is proposed to monitor the water levels of different areas of city through the wireless water level sensors as well as to capture live photos using CCTV camera. This will help authority not only to issue flood warning but also to plan flood mitigation measures and evacuation of people.

This study aims to examine the relationship between TQM (TQM) and primary school academic performance in Abu Dhabi with innovation as a mediator using SEM. A quantitative research design was utilized. A total of 342 teachers were chosen as a sample through quota and simple sampling technique. Data analysis using structural equation modeling was used. The results revealed that there was significant relationship between TQM and primary school academic performance was -0.50; significant relationship found between TQM and innovation. The further found that significant relationship was exist between innovation and primary school academic performance was 0.1.51 while TQM has significant relationship with innovation with .92. The result also found that innovation mediate on the relationship between TQM and primary school academic performance with partial mediation. It is hope of this study that TQM would be used by schools in Abu Dhabi region to improve primary schools’ academic performance. The implication of this study suggested that TQM should be internalize and use it to improve primary school academic performance in Abu Dhabi. However, a further investigation should be examining into the role the TQM play on primary school academic performance.

The direct regioselective oxidation of internal alkenes to ketones could simplify synthetic routes and solve a longstanding challenge in synthesis. This reaction is of particular importance because ketones are predominant moieties in valuable products as well as crucial intermediates in synthesis. Here we report the directed evolution of a ketone synthase that oxidizes internal alkenes directly to ketones with several thousand turnovers. The evolved ketone synthase benefits from more than a dozen crucial mutations, most of them distal to the active site. Computational analysis reveals that all these mutations collaborate to facilitate the formation of a highly reactive carbocation intermediate by generating a confined, rigid and preorganized active site through an enhanced dynamical network. The evolved ketone synthase fully exploits a catalytic cycle that has largely eluded small molecule catalysis and consequently enables various challenging functionalization reactions of internal alkenes. This includes the first catalytic, enantioselective oxidation of internal alkenes to ketones, as well as the formal asymmetric hydration and hydroamination of unactivated internal alkenes in combination with other biocatalysts.
Reaction-free concentration gradient generation in spatially non-uniform AC electric fields

Published: January 2022

The ability to generate stable, spatiotemporally controllable concentration gradients is critical for both electrokinetic and biological applications such as directional wetting and chemotaxis. Electrochemical techniques for generating solution and surface gradients display benefits such as simplicity, controllability, and compatibility with automation. Here, we present an exploratory study for generating micro-scale spatiotemporally controllable gradients using a reaction-free electrokinetic technique in a microfluidic environment. Methanol solutions with ionic Fluorescein isothiocyanate (FITC) molecules were used as an illustrative electrolyte. Spatially non-uniform alternating current (AC) electric fields were applied using hafnium dioxide (HfO2) coated Ti/Au electrode pairs. Results from spatial and temporal analysis, along with control experiments suggest that the FITC ion concentration gradient in bulk fluid (over 50 µm from the electrode) was established due to spatial variation of electric field density, and was independent of electrochemical reactions at the electrode surface. The established ion concentration gradients depended on both amplitudes and the frequencies of the oscillating AC electric field. Overall, this work reports a novel approach for generating stable and spatiotemporally tunable gradients in a microfluidic chamber using a reaction-free electrochemical methodology.

Experimentally determined protein structures often feature missing domains. One example is the C terminal domain (CTD) of the hepatitis B virus capsid protein, a functionally central part of this assembly, crucial in regulated nucleic-acid interactions, cellular trafficking, nuclear import, particle assembly and maturation. However, its structure remained elusive to all current techniques, including NMR. Here we show that the recently developed proton-detected fast magic-angle-spinning solid-state NMR at >100 kHz MAS is a game changer that allows to detect this domain and unveil its structural and dynamic behavior. We describe the experimental framework used and compare the domain’s behavior in different capsid states. The developed approaches extend solid-state NMR observations to residues characterized by large-amplitude motion on the microsecond timescale, and shall allow to shed light on other flexible protein domains still lacking their structural and dynamic characterization.
Etnografia osobista. Antropolożka i antropolog w terenie
Authors: Buliński Tarzycjusz , Posern-Zieliński Aleksander
Published: January 2022

The article presents the idea of personal ethnography, i.e. the anthropologists’ individual experiences that include practical, existential, and emotional dimensions of ethnographic field research. Such experiences and their details are largely absent in scientific papers, due to their apparent irrelevance for research results. Nevertheless, they form an indispensable part of ethnographic research, influencing its scientific findings. This article not only emphasizes the need to include this aspect of ethnographic research in the methodological reflection, but also points out the differences and similarities between personal ethnography and autoethnography, following the main threads of personal experiences from fieldwork.

Ciało i naród. O doświadczaniu uczestnictwa i pozycjonowaniu antropologa w terenie
Authors: Trzeszczyńska Patrycja
Published: January 2022

This article offers reflections arising from my three-year field research with the Ukrainian diaspora in two Canadian cities. Drawing on this field experience, I present the body as a research tool and the impact of work performed by the ethnographer’s body. I discuss my multi-sensory field experience and the experience of participation, which are inter- twined with the increasingly important issue of ethnographer’s positionality in the field, and – in my view – the utopian freedom to choose or negotiate professional identities. My considerations are embedded within the insider-outsider dialectics (not opposition) and point to the contextual “nativeness” and “strangeness” of the researcher. I claim that the act of attribution of social class and ethnicity by our field partners influences our field- work and may have long-lasting consequences in the ethnographer’s later life, including their private life. I also discuss the fluidity and contextuality of a researcher’s familiarity with their field, including research situations where fieldwork is done with “one’s own people” or in cooperation with “one’s own people”, i.e. when and how familiarity is trans- formed into strangeness.
Inicjacje terenowe i rozwojowy wymiar doświadczania „pola badawczego”. Opowieści o wojnie, zesłaniu i terenowym modus operandi
Authors: Kość-Ryżko Katarzyna
Published: January 2022

Ethnographic field research involves not only work, but also personal and existential experience. Sometimes it is routine, ordinary, and on schedule, but generally, it is not without difficulties and challenges. I discuss some of these in this article. The analysis is based on my own research experience, the common feature of which is the transgressive nature of experiences related by people and issues generally defined as “difficult”. My research projects involved war victims (exiles, refugees, deportees), i.e. people who often found themselves in life-threatening situations, had experienced loss, trauma and death of their relatives. Our meetings and interviews had cognitive, psychological and devel- opmental dimension, both in a personal and professional sense. I refer to these situations as “initiatory” experiences, as they constitute significant turning points in my perception of reality and my approach to research as a profession. In this paper, I discuss both meth- odological challenges related to research deemed difficult, as well as dilemmas related to ethnographic epistemology and the auto-ethnographic turn. My main concern here is whether and how to write about what is happening on the margins of field research and the personal struggles involved in such research.
