Securing the city, making the city: Property guardianship and dispersed policing in urban space
Authors: Shurety Elara
Published: July 2022

This article addresses the phenomenon of contemporary property guardianship, a type of building security by live-in occupants, who pay below-market rents, as a growing method of dispersed policing. While the centrality of property security is often foregrounded, both in existing literature on the topic and by property guardian operators, this research charts the increasing use of property guardians as operationalised agents in the surveillance and regulation of urban space. Within this, it looks at property security through an understanding of the building as a spillover site, the security for which has ramifications for wider urban space. Through analysis of how property guardians provide security within a wider remit than typically understood, it underscores guardianships relationship to broader security regimes. In light of its findings, it readdresses the role guardianship plays within the context of urban regeneration and gentrification. Through focusing on guardianship in London, with reference to other U.K. cities, it examines closely at borough-level local authorities use of guardians to further understand the position of guardianship-as-policing within regeneration. As such, it engages with the ways that property guardianship, as with other modes of policing, is concomitant with efforts to reorganise and remake cities. This research builds on previous scholarship within the topic of guardianship, while drawing on work from fields such as urban studies, policing studies and abolitionist thought, as well as reportage, promotional material, and both local and national policy. Through use of interviews and questionnaires, this article centres the experiences of guardians, and their relationship to their duties. It attempts to understand the subjectivities produced and actively sought by such dispersed methods of policing activity, which are undoubtedly reliant partly on the precarity of those enacting them.
Ciudad Constituyente: The dispute for the right to habitat beyond the constitutional moment in Chile
Authors:   Ciudad Constituyente
Published: July 2022

In October 2019, Chilean social revolts deployed and conquered a popular ‘constituent power’ that shook the ‘constituted power’ and the institutional structures that sustain it: those that have always been in power, the same old ways of doing things, the status quo that never changes, and those structures and processes that have harmed our society so much and for so long. In other words, the social reproduction that has been co-opted by the market, and a deliberately unequal and unrepresentative political-economic system. The constitutional moment that Chile is experiencing invites us to reflect upon and mobilise what made us recognise ourselves in the revolts of 2019. It is a moment that opens up new doors to redefine life in the territories. During this political moment, new platforms such as Ciudad Constituyente –a collaborative space for organisations of the people of Chile linked to habitat– have been created: a network organised upon democratic, anti-neoliberal, environmental and feminist principles. A collaborative space that seeks to move towards human dignity in neighbourhoods, cities and territories, with a focus on human, social and environmental rights at the centre of the constitutional debate.
Vecinas ≠ neighbours: La política del lenguaje en la lucha por la vivienda en Barcelona
Authors: Rivera Blanco Carla , García-Lamarca Melissa , Ferreri Mara
Published: July 2022

Esta Conversación surge de la curiosidad y las reflexiones de colaboradoras del Radical Housing Journal sobre el creciente uso del término vecinas —en inglés, neighbour— en las luchas por la vivienda en Barcelona en los últimos años. Desde nuestra participación en la lucha por el derecho a la vivienda en esta ciudad, quisimos explorar más profundamente la dinámica detrás de la palabra vecina a través de una conversación con tres activistas por la vivienda residentes del barrio de Sant Andreu de Barcelona. A partir de sus vivencias y activismo, nos explican qué significado tiene la palabra vecinas, en qué medida su uso señala un giro discursivo, el motivo de su feminización, las convergencias y divergencias —y también la inclusividad / exclusividad— de su uso entre diferentes grupos y, finalmente, lo que ha significado en el último año durante la pandemia de Covid-19 y el no retorno a la normalidad.
Celluloid Critique: Documentary Filmmaking and the Politics of Housing in Berlin’s Märkisches Viertel
Authors: Vasudevan Alexander
Published: July 2022

This is a paper about radical filmmaking and housing justice in the Märkisches Viertel in the 1970s. The satellite estate on the outskirts of West Berlin was one of the largest housing projects in West Germany and, for many residents, a space of increasing marginality and insecurity. As this paper argues, it was also a site of experimental filmmaking that documented the conditions faced by residents living in the Märkisches Viertel. The paper focuses on a group of students closely connected to the Deutschen Film- und Fernsehnakademie (dffb or the German Film and Television Academy) who began in the late 1960s to film various political activities and discussions in the neighbourhood. It places particular emphasis on the work of Helga Reidemeister, a social worker and student at the dffb whose documentary films adopted a working practice that depended on the direct participation of the families and women, in particular, with which she collaborated. Through a close reading of her 1979 film, Von wegen ‚Schicksal’ (1979), the paper foregrounds Reidemeister’s role as a feminist filmmaker whose work explored the mechanisms of displacement faced by tenants living in the Märkisches Viertel and the wider ‘structures of feeling’ that they generated. At stake here, is a broader commentary on the history of housing struggles in West Berlin and the importance of documentary filmmaking as a methodology for housing justice.
Vibration Anesthesia for Propofol-Rocuronium Injection Pain
Authors: Guler Aygun , Ozcan Namik Nebi
Published: July 2022

ABSTRACT Objective: Despite numerous strategies for preventing or alleviating pain associated with propofol and rocuronium injections, it remains common and distressing for patients. Application of vibration is an effective method of reducing pain during facial cosmetic injections and some venipuncture procedures. But it has been studied in limited trials for the context of propofol or rocuronium injection pain. This randomized study aims to evaluate the effect of vibration anesthesia on the incidence and severity of propofol and rocuronium injection pain. Methods: Fifty-one patients who underwent elective gynecologic operations under general anesthesia, were randomized, into two groups. On the dorsal side of the hand, a 20 G intravenous cannula was inserted. In Group V (n=25), propofol and rocuronium was administered following 1 minute of pre-treatment with the vibration device on the intravenous catheter trace. In Group C (n=26) vibration was not applied before drug administration. Propofol pain was recorded according to McCrirrick and Hunter scale and rocuronium injection pain response was evaluated with a four-point scale. Results: The number of patients who experienced propofol injection pain, in the vibration group was significantly lower than in the control group (p=0.007). The percentage of pain free patients in Group V was 88%, whereas 46% in Group C. The incidence of withdrawal movements associated with rocuronium injection pain was also significantly lower in Group V (p=0.043). Percentage of pain free patients in Group V was 28% whereas 3.8% in Group C. Conclusion: Vibration anesthesia before propofol and rocuronium injection significantly reduced the injection pain. Keywords: Injection pain, propofol, rocuronium, vibration
Does Leg Raising Prevent Spinal-Induced Hypotension in Elective Cesarean Sections? A Randomized Controlled Study
Authors: Sari Mustafa Deniz , Ozyurt Erhan
Published: July 2022

ABSTRACT Objective: We aimed to investigate the effectiveness of the leg raising (LR) method in preventing spinal anesthesia-induced hypotension in elective cesarean section (C/S) operations. Methods: One hundred and forty term pregnant women were included in the study. The patients were divided into two groups as leg raising group (Group L, n=70) and the control group (Group C, n=70). After spinal anesthesia, a cushion was placed under the heels of the patients in Group L at an angle of 30 degrees with the horizontal plane. No intervention was made in Group C. The patients’ hemodynamic and operation data were recorded at determined intervals. Results: In Group L, hypotension was observed in 29 (41.4%) patients while 54 (77.1%) patients developed hypotension in Group C (p<0.001). Systolic and diastolic blood pressure values at the 2nd and 3rd minutes after spinal anesthesia were found to be higher in Group L (p<0.05). Furthermore, compared to Group C, the amount of ephedrine used in Group L was found to be lower (9.9±14.2 mg vs. 15.9±11.9 mg, p=0.007). Conclusion: The LR method applied in C/S operations reduces spinal anesthesia-induced hypotension and thus causes the need for less vasopressor. Keywords: Cesarean section, spinal anesthesia, leg raising, hypotension

Published: July 2022

ABSTRACT Objective: To study the effect of lumbar sympathetic block (LSB) with a mixture of local anesthetics and steroids on pain in patients with chronic ischemic lower limb disease. Methods: Retrospectively 23 patients were reviewed with peripheral arterial disease who underwent LSB using a mixture of 8 mg of dexamethasone, 80 mg of 2% lidocaine, and 4 mL of saline at 2 levels, L2 and L4, under the guidance of fluoroscopy. Recordings of the Visual Analog Scale (VAS) scores at 3 days before the blockage, and 1 month and 3 months after treatment were obtained. Results: The study included 20 (87%) male and 3 (13%) female patients. The mean age of the patients was 59.65±13.33 years. The patients’ post-blockage 3rd day, and 1st and 3rd month VAS scores were significantly lower than the baseline VAS scores (p<0.05). The proportion of patients with 50% improvement in the VAS scores at 3rd days, and 1st and 3rd months was 47.8%, 21.7%, and 21.7%, respectively. No complications or side effects were observed. Conclusion: Lumbar sympathetic block with a mixture of local anesthetics and steroids appears to be effective in patients who have non-reconstructable arterial occlusive disease, with reduced pain scores and low complication rates. Keywords: Sympathetic nerve block, claudication, visual analog scale, peripheral arterial disease, pain
The Effect of Ultrasound-Guided Transversus Abdominis Plane Block on Chronic Pain Experienced After Inguinal Hernia Surgery: A Retrospective Cohort Study
Authors: Simsek Fatih , Ozkan Gokhan
Published: July 2022

ABSTRACT Objective: The purpose of this retrospective study was to see how efficient ultrasound-guided transversus abdominis plane (TAP) block was on the incidence of chronic postoperative pain developing after inguinal hernia surgery. Methods: The records of patients who had unilateral elective grafted inguinal hernia surgery with the Lichtenstein procedure under general anesthesia between July 2018 and October 2019 were examined retrospectively. The patients were placed into two groups (total=70): those who did not receive intraoperative TAP block (Group 1, n=38) and those who received (Group 2, n=32). The patients were contacted by phone 6 months after the procedure, and it was learned and recorded whether they had chronic pain before the operation, the nature of the pain if any, whether it limited their daily activities or not. The Numerical Rating Scale was used to measure chronic pain, and values of 3 and above were considered chronic pain. Results: This study comprised a total of 70 participants, with 38 patients in Group 1 and 32 patients in Group 2. Patients with chronic pain incidence in the postoperative 6th month (n=21) accounted for 30% of all patients. There was no significant difference between the groups regarding chronic pain development [Group 1 (n=14, 36.8% ), Group 2 (n=7, 21.8%)]. It was observed that the patients’ pain was predominantly in the burning style. Conclusion: We concluded that the ultrasound-guided TAP block had no significant effect on the development of chronic pain.

Published: July 2022

Existing smart helmets in the market provide only limited functionalities for convenience and lack safety considerations to proactively prevent accidents. We followed a user-centered design process from which we present three major steps in this paper: user research, prototyping, and testing. Our user research revealed core use cases of a new smart helmet. An important usability issue is the way micro-mobility riders make their input while riding. Three alternatives (head gesture, push button, kick button) were evaluated and both quantitative and qualitative feedback was gathered from participants. The results show that head gesture interaction is natural and satisfactory considering the specific riding posture and traffic situations of micro-mobility users. We also present detailed specifications of the rolling head gesture used in our final prototype, as well as the user feedback methods for other functionalities such as a rear approach warning light and rear light.
Urban green network for the urban area of Milagro, Guayas, Ecuador
Authors: Maruri Diego , Vega Gabriela
Published: July 2022

Currently, a large part of the urban population resides in cities where there is little or almost no relationship between nature and the urban environment, which is a fundamental parameter for achieving quality of life for people. On the other hand, the disorderly and accelerated growth of informal settlements in search of different economic activities in recent years in the canton of Milagro, and the unbridled development of the sugar and cocoa agroindustry, has led to the deforestation of the native forest areas of the canton. The objective of this study is to promote the conservation and creation of new green areas in the urban area of Milagro by identifying and incorporating native tree species of the sector, which should be compatible with the ecosystems. In order to determine the needs of each sector, we identify and analyze the available useful green area surfaces, through the use of precision spatial geographic software that allows us to establish the exact areas of the territory under study and to relate them to the current population to arrive at the analysis of the urban green area index (U.G.I.), with the aim of establishing the urban green area index (U.G.I.), in order to create new spaces of green areas, with the result of increasing the index of urban green area within the parameters established by the Ministry of Public Health of Ecuador (M.P.H.), and establish a strategic planning as a consolidated axis for the city based on green concepts linked to sustainable land use planning.
Sustainable Transport Development Strategy in Developed and Developing Countries
Authors: Aribah Hanif Nita , Nurmandi Achmad
Published: July 2022

This study aims to explore the idea of sustainable transportation in the United States, China, Canada, and South Korea. Sustainable transportation has an essential role in developing a sustainable city that pays attention to an effectiveness-oriented transportation system that impacts the economy, the environment, and the quality of social life. The selection of case studies in four countries motivated the top four countries from the keywords sustainable transportation. This study uses a bibliometric analysis method using data sources from 306 articles (Scopus). The data search was carried out using the keyword "sustainable transportation" from 2012-to 2022. The highest number of research trends in the United States is 166 articles; China has 102 pieces, Canada has 46 papers, and South Korea has 26 articles. The data analysis stage was carried out using the Vos Viewer and Nvivo 12 Plus software. The results show that each country has a different focus measured from three aspects: planning, information, and investment. Planning factors include types of transportation, routes, costs, carbon emissions, and applications. The information aspect consists of estimation, trip, and performance. The investment aspect includes current demands and issues to shape future policies. Development strategy Sustainable Transportation in the planning stage only focuses on the use of vehicle emissions. In contrast, in the information aspect, it focuses on travel modes, then in the investment aspect, there is no attention to future policies related to issues that occur today. In the planning part of Sustainable Transportation, China has a varied focus, such as the type of transportation used, emissions, and the route used for transportation. In contrast, the Chinese state has not paid attention to this focus on the information and investment aspects. Meanwhile, Canada and South Korea have not focused on planning, information, and investment aspects. From these findings, it is hoped that it can provide input for various countries to pay more attention to these aspects to achieve sustainable transportation in smart cities. The concept of sustainable transportation is also helpful for achieving SDG's 11th goal.

Gamification or Game Design? A case study in the field of sustainable commuting.
Authors: Schillaci Domenico , Di Dio Salvatore , Filippi Mauro , Massa Francesco
Published: July 2022

In the last few years, the debate among designers and sustainability experts has brought attention to many different behavioural change approaches and techniques and particularly on “gamification” processes able to better motivate and engage students or even nudge people (consumers) to more environmentally and socially responsible habits (Mousumi, 2021).But since 2011, most of the contradictions about “gamifying” boring or unpleasant experiences have been loudly shared by game designers and thinkers worldwide (Bogost, 2014). It seems that the goal of changing people’s unsustainable behaviours can be achieved by designing brand new sustainable experiences instead of gamifying the unsustainable ones (Yusoff and Kamsin, 2015).This change of perspective represents the foundation of applied games, and it has been deeply studied during the applied research MUV2020 (723521 – muv2020.eu), led by the PUSH design laboratory within the Horizon2020 framework in the field of sustainable urban mobility (Di Dio et al., 2020).From June 2017 to August 2018, the research consortium has run extensive user research across Europe and developed a mobile app game based on the main gain mechanic of recording personal urban travels and a game narrative of sport.From September 2018 to February 2020, the consortium had run several tests in more than 20 cities to study the value of different interactions in terms of engagement and sustainability impact.After the COVID-19 outbreak, further experiments have been carried out by the research project spin-off’s MUV Benefit Corporation (muvgame.com). Thanks to more than 16.000 downloads, 500.000 kilometres recorded, and the CO2 reduction algorithm (validated in April 2020 according to ISO 14064-2), this contribution shows how various game dynamics nudged, with a different rate of efficacy, MUV’s players commuting behaviours.This contribution will extensively deepen applied and persuasive games, MUV App user research and game design, actual field data analysis on engagement rate and sustainable impacts.
AVATAR: Realistic customized virtual agents as emotional tutors for children with ASD
Authors: Guerrero Luis , Duchi Darwin , Delgado Juan , Campoverde Pablo , Ojeda Maryury
Published: July 2022

This work describes the generation process of a Human-Computer Interaction interface, intended to provide support in therapeutic interventions for children with Autism Spectrum Disorder (ASD). For the interface, realistic avatars were generated based on photogrammetry techniques, based on real human models. Resulting interface employs the "Wizard of Oz" method, whereby avatars become virtual puppets controlled by a remote operator. Using facial recognition, the avatars mimic the gestures and facial movements of human models while the voice is transmitted without any modification. In this way, interaction is completely promoted by the human model, avoiding the loss of attention that could be generated by delays produced by an automatic interaction system based on Artificial Intelligence. For the experimental process, we developed a mobile application that uses generated avatars as emotional trainers based on 6 basic emotions. App works like a serious game that allows users to identify emotions expressed by avatars by interpreting their gestures. Results showed a great acceptance by children with ASD to interact with the application and an excellent perception by therapists who considered this tool as a very useful support during therapeutic processes.
A comparison between usability evaluation methods: A case study in the E-Commerce domain
Authors: Paz Freddy , Asrael Paz Freddy
Published: July 2022

Usability is a quality attribute that nowadays cannot be ignored by software development teams. Designing a software product that is difficult to use and understand, where the user is lost, and the achievement of the user's objectives is prevented, can cause users to choose to use similar alternatives. For this reason, Human-Computer Interaction specialists have developed a set of usability evaluation methods that allow problems to be identified to guarantee an appropriate level of user-friendliness of the application. However, there is a large disagreement between the authors as to which is the best method to use. In this study, the results of two of the most used methods to carry out usability evaluations of software products have been compared: the questionnaire and the heuristic evaluation. On the one hand, the questionnaire has turned out to be the method most used by the scientific community because it is easy to use and does not require much material preparation. However, the majority of questionnaires have been aimed at being answered by end-users. In a previous work, we developed a questionnaire for UX practitioners that in this case has been used for the evaluation of an electronic commerce application. On the other hand, heuristic evaluation is a method where specialists verify compliance with certain principles in the design of the graphical interfaces of a software product. It is also widely used like questionnaires but requires more planning and execution time. In this research, it is possible to evidence the differences in the type of problems that can be identified by each of the methods. In conclusion, it is possible to mention that although a percentage of problems are identified that can only be identified with one or the other method, the recommendation is to use both methods as the results complement each other.
Understanding human decision-making when controlling UAVs in a search and rescue application
Authors: Hart Sophie , Banks Vicky , Bullock Seth , Noyes Jan
Published: July 2022

The introduction of Unmanned Aerial Vehicles (UAVs) within search and rescue missions provides human operators with ‘eyes in the sky’. However, little attention has previously been paid to the implications of this type of technology on the decision-making procedures of search and rescue teams; in particular, the human operator responsible for extracting and analysing UAV sensor data in order to achieve the mission objective, typically to locate missing people.Within the field of Human Factors, theoretical decision models have been used to identify user requirements for interfaces, training protocols, workstation layouts, and decision aids. We propose that decision models can be applied to the study of Human-Robot Interaction. Thus, the current paper presents a literature review of decision models used within Human Factors. The provision of a UAV within a Search and Rescue operation is used to case study the utility of these decision models for capturing the aspects of decision-making exercised by the sensor operator.
Technical Requirements to Design a Personal Medical History Visualization Tool for Doctors
Authors: Hossain Forhad , Islam Rafiqul , Taufiq Ahmed Mostafa , Ahmed Ashir
Published: July 2022

A doctor needs to know the patients’ medical history to investigate the root cause of symptoms. Traditionally it is done by a questionnaire at the clinic’s reception desk, or the doctor asks a series of questions to obtain a relevant medical history. An incomplete or wrong medical history affects the doctor’s decision. The challenge for a busy doctor is to obtain all the relevant medical history in a short period of time accurately and without missing any important history. Affordable clinics employ an assistant or junior doctor to sort out all the paper-based medical history and mark the important points. It increases doctors’ work performance by saving doctors time and making room for consulting more patients. But not all the small clinics can afford such assistants. This paper lists the technical requirements to develop a personal medical history visualization tool to increase doctors’ productivity.

Published: July 2022

In this work a design of an integrated aero-thermal auditorium, with complex topology, is made for winter conditions. The three-dimensional geometry of the auditorium is obtained using cylindrical coordinates. Auditorium thermal response is obtained using the Building Thermal Response (BTR), an own research software. The numerical model is based on mass and energy balance equations, considering phenomena such as radiation, convection, conduction, evaporation and diffusion. The BTR, whether in a transient or permanent regime, allows the assessment, among others, of the level of thermal comfort and the indoor air quality (IAQ) in the auditorium. Here, the thermal comfort is assessed by the Predicted Mean Vote index and the IAQ is assessed by the concentration of dioxide carbon. The auditorium has windows on the east and west facades that allow the entry of solar radiation during the early morning and late afternoon, respectively. The maximum occupancy of 420 people was considered. The ventilation system airflow rate was adjusted to obtain the best compromise between the occupants' thermal comfort level and the IAQ level.

Authors: Man Tin Lai
Published: July 2022

The paper proposes artistic and computational approaches to investigate the ability of matching learning to synthesise and manipulate the image dataset into artwork creation. By using the Generative Adversarial Network (GAN), it is observed how the machine algorithms are able to learn artistic styles and manipulate relevant pictures to generate digital artifacts, in particular, the images generated through latent space interpolation. Referring to an artwork of Pablo Picasso, the paper also aims at observing the collages being generated by GAN in order to understand and compare the machine vision with human vision in collage and artwork creation. And finally, to explore the process of seeing through the phenomenology of embodiment, trying to understand how the objects could be visible to us through the machine and artificial intelligence without being "bodily involvement in the world".

Published: July 2022

One of the major interests of higher education institutions is the creation of transformative methods that favor the instructional process, where students participate in their academic training through the generation of dynamic and open areas of interaction. This study describes the development of a strategy to understand the stock market with the application of technological tools based on 3D virtual environments. These environments known as Metaverses are immersive platforms that create experiences in an extended reality. The strategy consisted of designing and building a virtual learning environment on the Second Life platform to strengthen students' stock market skills. The instructional design was developed with the ADDIE (Analysis, Design, Development, Implementation and Evaluation) methodology focused on five themes: The world financial system, capital markets, products traded on the stock exchange, stock market indexes and famous cases in stock markets. The proposal was evaluated with 73 students of business administration career of a private university in Ecuador. According to the statistical information, 56% of the students have not used a metaverse before, 56% have not even practiced in real environments or simulators to learn the dynamics of the stock markets, 85% have not interacted with an avatar in cyberspace before, 78% consider the use of interactive spaces interesting, 79% were motivated to participate in 3D virtual environment strategies, 95% of students were engagement with active methodologies, 97% support the continuation of classes in the Second Life platform and 100% mention that it is necessary to create metaverses that allow them to interact and learn in a better way. The implementation of virtual worlds in e-learning platforms reinforces knowledge and management skills in the stock market
Designing trustworthy IoT systems: Critical challenges and approaches for generating value
Authors: Lee Boyeun , Gradinar Adrian , Cooper Rachel , Coulton Paul
Published: July 2022

At the end of the 20th century, the Internet of Things term was first introduced. Since then, the phenomenon behind this technological development is still fast-growing with estimates of more than 75 billion IoT devices readily connected to the Internet by 2025. During use, each of these devices generates valuable data for the end-user whilst negotiating the cybersecurity challenges low secured IoT devices employ. Whilst these security challenges have presented businesses with extensive opportunities for value creation, there are only a handful of studies exploring the challenges and opportunities related to security, privacy, and trust in IoT platforms and systems from a business perspective. Through a series of semi-structured interviews with top-level managers of different organisations across various industries in the UK, a methodological approach was developed to capture and address IoT value creation from the business’ perspective in which trust factors are at the core of the value creation process. This research identifies four critical challenges and approaches to value creation namely: continuous scaling-up, co-creation, data-driven value creation, and user-centric design. These approaches provide comprehensive understanding on how value creation activities are critically related to cyber security and how they affect trust factors. This study is timely for an academic audience since it contributes to initiating the body of literature regards cybersecurity and business application whilst from a managerial perspective it enables industry practitioners to generate value from IoT whilst better understanding the relations between the value creation activities and cybersecurity concerns.

Published: July 2022

An ergonomic study was carried out to evaluate the manual handling of loads and identify possible musculoskeletal conditions to establish preventive measures to reduce the risk in the worker in the balancing unloading area. To identify risk factors, information was collected through direct observation and photographs. To establish the ergonomic risk in the manual handling of loads, the OWAS (Ovako Working Analysis System) evaluation method was applied with respect to the postures to which it is exposed. By conducting the evaluation, sixteen postures were analyzed using the encodings of the back, arms, legs and load postures. Positions 9, 10 and 11 are the ones with the highest risk for the worker, obtaining a risk category 4, this means that it is necessary to adopt corrective actions as soon as possible. In addition, the Snook and Ciriello method was applied for the evaluation of load handling, for this method the ERGOSoft PRO software for Windows used in Ergonomics is used to facilitate the work of the prevention specialist with data collection from mobile technology. The results for the initial force gave a risk level between 1.5 - 2.0 with a value of 1.82 having a high risk due to being exposed to a significantly high force, for the sustained force the risk level is> 2.0 with a value of 3.33 having a very high risk due to being exposed to high force and overexertion, it is recommended that you include in your budget the performance of complementary examinations every six months for the control and prevention of musculoskeletal injuries due to activities that they involve efforts in the postures of the back, arms and legs.

Published: July 2022

As life expectancy increases, the likelihood of more falls and fall-related hospitalizations increases with a significant impact on the health system. Given the high incidence of falls in healthy elderly people, in order to prevent them, it is necessary to identify predisposing risk factors, analyze the specific needs of the subjects and use a targeted preventive strategy. This paper investigates the influence of multidimensional health parameters on the fall risk of community-dwelling older people, living in inner areas of Marche Region (Italy). Multidimensional data on the global health of each individual has been collected among several health domains (i.e., mobility, psychological, nutritional, cardiological, social). Statistical analysis has been applied for the assessment of the relationship among the defined health variables and the influence on the fall risk. The binary logistical regression analysis has produced a statistical model with good characteristics of fit and good predictability. The following features have been proven to be strong predictors of fall: female (OR for Gender, 5.526; 95% CI, 1.49–20.53), limited range of movement (OR 3.278; 95% CI, 1.01-10.68), diabetes (OR 4.487; 95% CI, 1.02-19.80), previous syncope (OR 7.686; 95% CI, 1.01-58.55), and body mass index (OR 1.176; 95% CI, 1.03-1.35). Future work will allow the development of a fall prediction index to have a framework of the elder’s global health status and to define a personalized intervention strategy for any adverse event prevention.

Published: July 2022

This study aims to analyze the Indonesian government’s social media as a follow-up to promote the tourism industry after the COVID-19 pandemic. This study used a Qualitative Data Analysis Software (QDAS) approach. The source of this research data was @Kemenparekraf, the Ministry of Tourism and Creative Economy’s official Twitter account. The research data analysis phase used the NvivoPlus12 software tools to present descriptive quantitative data. The results of data analysis showed that @Kemenparekraf social media had high activity in November with 181 tweets and at least 126 tweets in August. Each information on the Ministry of Tourism’s Twitter account was different, thus confirming that the Ministry of Tourism and Creative Economy’s account was active in providing information about tourism and the cultural wealth of Indonesia. Social media utilization was carried out through various promotions through hashtags.

CFD SIMULATION OF HEAT TRANSFER THROUGH A ABSORBER PLATE OF SOLAR AIR HEATER WITH ARTIFICIAL ROUGHNESS
Authors: Tiwari Swarnim , Dubey Kamlesh
Published: July 2022

Solar energy is abundantly available and its use in various applications has always been of great interest among the common man, designer, engineer and researchers. One of the applications among several is in heating of air. Hot air is of use in domestic and industrial purposes. The efficiency of any solar air heater can be understood as the ability of the solar air heater to transfer the heat from the absorber plate where the solar radiations are absorbed to the air flowing over this. Since the heat transfer is affected by the surface of the absorber plate, study of surface conditions becomes essential for improving the efficiency of the heater. Many researchers have done several studies for the improvement of the heat transfer from the absorber plate to the air. In this paper, the authors have simulated the heat transfer from an absorber plate in which artificial roughness elements are provided. The simulation results show that the heat transfer is improving because of the turbulence development near the surface of the absorber plate. The temperature and velocity contours have been presented in this paper. Temperature, velocity, heat transfer coefficient and Nusselt number plots for the absorber plate are also shown.
