Authors:   Academy of Marketing and Social and Information Technologies — IMSIT, Petrakova Anna S.
Published: February 2022

The article examines identity processes, which under the conditions of total informatization experience manipulative interventions that transform identity foundations. The communicative approach was chosen to analyze the impact of social communications, implemented mainly in digital formats, on identification processes. As a result, it was found that manipulation as a method of hidden social control is used as one of the technologies for the formation of collective social consciousness. The introduction of certain stereotypes, socio-cultural patterns and attitudes into the identity basis of the individual through the means of digital communication leads to the fact that the individual takes them as the basis for the implementation of identification processes and, as a result, there is a transformation of personal identity.

Published: February 2022

The article examines the features of the regional and ethno-confessional identity of students in Tyumen. The empirical material is based on the results of a study that was conducted with the participation of the author in October, 2021. The survey data of the studied cohort are presented in comparison with the answers to the corresponding questions of the adult population of the region. The paper describes such aspects of the respondents’ regional identity as: the structure of civil values, self-assessment of belonging to the Russian people; the role and place of the concept of “Motherland”; views on regional and geographic consolidating factors. In the description of ethno-confessional identity, the specifics of defining one's own ethnicity and an assessment of its importance are considered. The factors of ethnic consolidation and preservation of national identity have been studied. The influence of the ethnic group on various spheres of life is shown; the relationship of various ethnic groups with each other. The linguistic and confessional aspects of the issue under study are partially touched upon. The main conclusions of the work are related to the fact that student youth are more cautious in assessing their patriotic sentiments and show more moderate positions on issues related to regional identity. Students show ethno-religious attitudes to a lesser extent, are more tolerant of representatives of other identities and are more often focused on creativity, self-realization, and personal success.

Published: February 2022

This study aims to explore the relationship between the influential factors of online learning and the satisfaction of economics and business majors with the quality of their training in the context of the Covid-19 pandemic. A total of 900 students in private universities completed a questionnaire. The principal findings of this research are that the students are satisfied with their online learning and that learning conferencing software is the most important driving factor leading to the students’ satisfaction when compared with learning conditions and learning devices. Another interesting finding is that the experience of using learning conferencing software results in a slight difference in the students’ perceived level of satisfaction, adding that users with more than two years’ experience are more satisfied with their training quality than users with less than one year’s experience. However, the results also show that students want to switch to offline learning when the pandemic is over. This study should, therefore, be of value to higher education authorities wishing to understand their students’ perceptions of online learning. In addition, results from the study suggest more managerial approaches as well as improve the online teaching quality during the pandemic.

Published: February 2022

As a currently popular technology, the use of smart cards continues to increase in various fields and the rapid development of technology. Therefore, data security stored on a smart card needs to focus on avoiding misuse of data by unauthorized parties. However, it is not enough for the security mechanism to be carried out only during the communication process of sending data. Then, the mechanism for securing data on the smart card also needs to be done. In this study, a data security technique using dynamic keys is proposed by changing the key and access conditions on the smart card according to predetermined rules. Dynamic keys are a new mechanism proposed to authenticate smart cards using a different key on each card. This technique ensures that the keys used to access each smart card are different so that the risk of data duplication and modification threats can be minimized. In addition, this mechanism is a low-cost security privacy protection. The test results show that the data security technique using dynamic keys ensures that read and write access to the smart card can only be done if the keys match the rules.

Published: February 2022

Law No. 36 of 1999 concerning Telecommunication has brought many changes, especially in the development of telecommunications infrastructure in Indonesia. However, the penetration of telecommunications services in the forefront, outermost, and backward regions is still relatively low. The government has made various efforts in terms of minimizing the gap in telecommunication services between urban and rural areas through various programs. However, an acceleration is needed so that the service disparity can be immediately overcome. One of the telecommunications products that can be applied to overcome these barriers is the Mobile Virtual Network Operator (MVNO). This study evaluates the most appropriate type of MVNO model to be applied in Indonesia by implementing the Consistent Fuzzy Preference Relations (CFPR) method. This method is able to accommodate expert opinion through a series of scientific steps so as to produce weights for each alternative type of MVNO model. The results obtained are that the most appropriate model to be applied in Indonesia by taking into account the criteria given. The implementation of this model is expected to be able to encourage the optimization of BTS USO that has been declared by the government.

Authors: Rasyad Muhammad Abdullah , Dewanta Favian , Astuti Sri
Published: February 2022

Object detection gives a computer ability to classify objects in an image or video. However, high specified devices are needed to get a good performance. To enable devices with low specifications performs better, one way is offloading the computation process from a device with a low specification to another device with better specifications. This paper investigates the performance of object detection strategies on all-in-one Android mobile phone computation versus Android mobile phone computation with computational offloading on Nvidia Jetson Nano.  The experiment carries out the video surveillance from the Android mobile phone with two scenarios, all-in-one object detection computation in a single Android device and decoupled object detection computation between an Android device and an Nvidia Jetson Nano. Android applications send video input for object detection using RTSP/RTMP streaming protocol and received by Nvidia Jetson Nano which acts as an RTSP/RTMP server. Then, the output of object detection is sent back to the Android device for being displayed to the user. The results show that the android device Huawei Y7 Pro with an average FPS performance of 1.82 and an average computing speed of 552 ms significantly improves when working with the Nvidia Jetson Nano, the average FPS becomes ten and the average computing speed becomes 95 ms. It means decoupling object detection computation between an Android device and an Nvidia Jetson Nano using the system provided in this paper successfully improves the detection speed performance.

Authors: Ustyannie Windyaning , Setyaningsih Emy , Iswahyudi Catur
Published: February 2022

The main problem in producing high accuracy software defect prediction is if the data set has an imbalance class and dichotomous characteristics. The imbalanced class problem can be solved using a data level approach, such as resampling methods. While the problem of software defects predicting if the data set has dichotomous characteristics can be approached using the classification method. This study aimed to analyze the performance of the proposed software defect prediction method to identify the best combination of resampling methods with the appropriate classification method to provide the highest accuracy. The combination of the proposed methods first is the resampling process using oversampling, under-sampling, or hybrid methods. The second process uses the classification method, namely the Support Vector Machine (SVM) algorithm and the Logistic Regression (LR) algorithm. The proposed, tested model uses five NASA MDP data sets with the same number attributes of 37. Based on the t-test, the  <  = 0.0344 < 0.05 and the  >  = 3.1524 > 2.7765 which indicates that the combination of the proposed methods is suitable for classifying imbalanced class. The performance of the classification algorithm has also improved with the use of the resampling process. The average increase in AUC values using the resampling in the SVM algorithm is 17.19%, and the LR algorithm is at 7.26% compared to without the resampling process. Combining the three resampling methods with the SVM algorithm and the LR algorithm shows that the best combining method is the oversampling method with the SVM algorithm to software defects prediction in imbalanced class with an average accuracy value of 84.02% and AUC 91.65%.

Published: February 2022

In general active sun trackers move because they respond to light sensors that measure the intensity of sunlight. However, sensor-based trackers are usually more expensive than sensor-less trackers. In addition, based on several studies, a comparison between the sensor and sensorless based tracker only reports lower tracking error and higher power generation for sensor-based than sensorless tracker. However, it does not include an analysis of energy use on the sensor. Therefore, this study aims to design a sensorless closed-loop tracking system for solar panels with two degrees of freedom. The tracking controller in this study is based on the Fuzzy Logic Controller (FLC) method. In this study, a dual-axis PV can increase power output by 20.2% compared to a fixed PV (0 ° axis position). In comparison to a fixed PV, dual-axis PV adjusts the solar panel perpendicular to the sun's position to optimize electrical conversion.

The study aims to develop automatic transplanting equipment for chain pot seedlings. We intend to practice the shaft tillage cultivation using an autonomous farming robot. We had developed an autonomous working vehicle and automatic transplanting equipment for plug seedlings used in shaft tillage cultivation. To reinforce the robot system’s versatility, we developed transplanting equipment for the chain pot seedlings. We experimentally investigated the transplanting performance. Approximately 84% of the seedlings were automatically transplanted using the developed equipment. Since the equipment was performed well in the failure samples, we assumed that the cause of such failures was attributed to seedling quality. In addition, we measured the power consumption of the equipment used to build an electrical power supply system. Consequently, we calculated the power requirements for each process. Compared with the plug seedling equipment developed in the previous study, the chain pot seedlings’ power requirement was lower because the conveying actions of seedlings were different. In the next stage of our research, to construct a fully automatic system, we will consider the seedling raising method in which seedlings can become uniformly high-quality and investigate the plant establishment performance using the developed equipment.

In this study, an active exercise function was added to a continuous passive motion device, which is widely used in rehabilitation therapy for function enhancement. The objective is to reduce physical overwork on the part of physical therapists and promote self-rehabilitation in patients. Impedance control based on position control was applied to provide active exercise load. Various active exercise loads are required to reproduce daily life muscle activity. Accordingly, a friction load model was introduced in the impedance control system. The effects of increasing the types of active exercise loads were evaluated by analysis of muscle activity during experimental tests, and a new muscle activity that could not be attained by the conventional spring-mass-damper load model was confirmed.

Published: February 2022

This paper describes a fish-like robot with a deformable outer shell fabricated using a silicone mold. Based on the difference in the contact condition between the serial-link robot and the shell, the fabrication methods are classified into embedded type and skin type. This study analyzes the mechanical properties of embedded and skin-type underwater robots from the viewpoint of material mechanics. A low-torque motor can sufficiently drive the skin-type underwater robot if the friction coefficient and pressure between the skin and the link are appropriately selected. Furthermore, the outer skin of the fish-like robot can be easily fabricated by defoaming in the chamber of a vacuum-packaging machine. Finally, the performance of the skin-type robot in air and underwater was assessed through several experiments.

Published: February 2022

This paper presents a miniature motorcycle robot developed for the purpose of research on attitude control at the time of traveling and resting a motorcycle mobile body. The miniaturization has been achieved by developing a small board using MPU and FPGA as a controller. This motorcycle mobile robot has a mechanism featuring the use of an inertial rotor in addition to the steering mechanism of a common motorcycle. The use of the inertial rotor enables the balance to be maintained even at the time of rest. Using this function of being able to maintain balance even at the time of resting, we measured the effect of a steering operation on balance and successfully compared it with the theory. Furthermore, balanced traveling is achieved by using only an inertial rotor at a low speed and only steering at high speed.

Published: February 2022

This paper presents a communication robot system with a simple LED display for representing timing for turn-taking in human-robot interaction. Human-like conversation with non-verbal information, such as gestures, facial expressions, tone of voice, and eye contact enables more natural communication. If the robots could use such verbal and non-verbal communication skills, it would establish a social relation between a robot and human. Timing and time interval for turn-taking in human communication are important non-verbal cues to efficiently convey messages and to share opinions with each other. In this study, we present some experimental results to discuss the effect of response timing for turn-taking in communication between a person and a robot.

In this paper, we proposed a distributed controlled gait rehabilitation and locomotion support system through human-robot cooperative control, and combination of two cane-type walking support robots (left and right) and one wheelchair robot to support the walking and locomotion of a person in need of walking assistance. The proposed system can realize five types of motion support from gait training to daily motion support, using three types of motion support modes with a distributed robot control system comprising up to three robots to support the user’s independence for walking and moving. The cane-type walking support robot moved in response to the manipulation force applied to the robot by the user, and can realize walking/movement support in all directions through the omnidirectional traveling part. In addition, the height of the robot can be adjusted according to the user’s physique, and the motion characteristics can be set according to the user’s walking ability. The wheelchair robot has a seat that can be raised, lowered, and tilted to provide standing assistance for the user and mobility support as an electric wheelchair. In this study, we developed a prototype of the proposed system and demonstrated its feasibility for five types of assistive actions in experiments with healthy subjects.

The aim of this study was to propose a tread swing mechanism for lower-limb strength training devices and to confirm its effects. In the standing position and for training the lower limbs, if the tread-surface angle is inappropriate, the posture of the knee joints gets affected, and knee adduction/valgus moments, which result in knee stress, get generated. The target training exercises are the front-back leg scissors and open-close leg triangle exercises. With regard to the swing of the tread, it is necessary to realize a pitch/yaw rotation and a roll/yaw rotation for the former and the latter exercises, respectively. As a result, knee joint stress can be reduced by moving the center of pressure (COP). The proposed mechanism has a further differential mechanism that utilizes the difference between the pulley diameters. The translational movement force of the tread is transmitted as the torque of the swing motion for the pitch, roll, and yaw through the effects of a differential mechanism. The rate of the swing angle can be changed by adjusting the pulley diameter. As a result of evaluating the effect of exercises using a manufactured device, it was confirmed that the tread performed a predetermined swing motion. It was also confirmed that the COP position changed. Therefore, it is expected that knee joint stress will reduce. Rehabilitation and strength training that result in small knee joint stresses and generate large muscle load are in great demand for people experiencing knee joint failure.

For autonomous navigation, localization in an environment is a fundamental capability. In this regard, it is necessary for robots to have environmental maps. The environmental maps are, in general, built beforehand through SLAM. On the other hand, the authors have focused on cadastral data including road and building information. In this paper, we propose a localization method using an environmental map based on the cadastral data. The robot is assumed to be equipped with 3D LiDAR. However, the cadastral data does not include natural objects, such as trees. Moreover, the position of a building in the cadastral data is sometimes different from its actual position in the environment. For data association between the sensor measurements and environmental map, we describe point cloud processing. Furthermore, we use an RGB-D camera to obtain a dense point cloud. In the navigation experiments, we show that the robot is able to move towards the destination autonomously through the localization in the map.

Over the last few years, numerous robotic ankle-foot orthoses have been developed to help stroke patients optimize gait rehabilitation. In this paper, we present a study on the effects of assistance on dorsiflexion-restricted gait. Our high-dorsiflexion assistive system aims to provide full assistance to realize passive training of dorsiflexion during the swing phase and prevent compensatory movements. This system, which includes a McKibben-type artificial muscle and an air source, is lightweight and provides a high-dorsiflexion torque. The device could help boost overground gait rehabilitation in stroke patients. With this system, we conducted an experiment on five healthy participants whose dorsiflexion movements were restricted, and the extent of their compensatory movements differed. The results of the processed surface electromyography data differed significantly when dorsiflexion movement was assisted by our system. The spatial parameters also showed significantly improved compensatory movement inclination with sufficient assistance. These results indicate the potential of our system to assist in passive training of ankle dorsiflexion movements and to prevent incorrect gait in patients with low dorsiflexion abilities.

Published: February 2022

A two-wheeled vehicle using bimetal sheets that travels on a hot horizontal surface by using only thermal energy is proposed herein. Each wheel is wrapped with a bimetal sheet, and the deformation of the sheet causes the wheel to roll. The rolling motion is investigated based on a simple physical model to provide insights into the rolling principle and its characteristics. Subsequently, by comparing several different wheel structures, the optimal wheel structure for the vehicle is selected. The performance of the developed vehicle is tested on a hot plate whose surface temperature is 100°C higher than the ambient air temperature. It is discovered experimentally that the vehicle can travel at a speed of approximately 60 mm/s when no load is applied. The vehicle can travel by supporting a load of approximately 400 g, which is almost double its weight.

The pointing operation using a mouse is widely implemented as a method for an operator to intuitively operate a pointer on a display. However, the dynamic characteristics of the pointing operation and pointer movement, such as inertia and viscosity, cannot be adjusted using ordinary pointing devices. As an alternative to a mouse pointing system, in this study, we propose a novel haptic pointing system in which the dynamic characteristics of the pointing operation and pointer movement can be adjusted using a robot manipulator under mechanical variable admittance control. The dynamic characteristics of the robot motion and pointer movement are varied sequentially during the pointing operation by varying the inertial and viscosity parameters of the proposed admittance control strategy using a mechanical device attached to the robot manipulator. The experiment was conducted to reveal the effectiveness of adjusting the pointer movement dynamics by modifying the pointer movement control loop and the ratio of the operating force with respect to the amount of pointer movement. The experimental results demonstrated that the performance of the pointing operation was improved by appropriately adjusting the pointer movement dynamics.

Wheelchair users require the assistance of station staff when boarding trains due to step differences and the gap between the platform and train. Therefore, they feel stressed in the movement with the train. In addition, the burden on station employees is increasing with the increasing number of wheelchair users at railway stations. In this study, an assistance device is proposed to address these challenges.

What if und What will … be like?
Authors: Hausmann Robert
Published: February 2022

Gegenwärtiges In-der-Welt-Sein scheint vom Zukünftigen, vom Spekulativen, von ungleichzeitigen und permanent vorläufigen Bedingungen bestimmt zu werden. Digitalität hat Subjekte, Räume und Alltagspraktiken durchdrungen. Mitten in diesen postdigitalen Verhältnissen entwerfen nicht nur zeitgenössische oder besser gesagt «zukunftsgenössische» Künstlerinnen und Künstler wie Mary Maggic (Avanessian und Malik 2016, 24), sondern auch TikTokerinnen und TikToker Szenarien des What-if und What-will-…-be-like. Sie erzeugen dabei spekulative Spielräume für (Un-)Möglichkeiten und Projektionen von Zukünften im Hier und Jetzt. Im Beitrag werden diese Modi von Zukünftigkeit in den Blick genommen und danach gefragt, wie diese Taktiken des Erweiterns und handelnden Erprobens von Zukünften neue Impulse für Lernen und Bildungsprozesse eröffnen.

The aim of the proposed article is to highlight the life path and scientific achievements of Jan Gordzyalkowski (1862–1944), one of the most famous experts of veterinary medicine in interwar Poland, a well-known veterinarian practitioner, microbiologist, encyclopedist, one of the founders of veterinary education. The presentation of the materi-al in the article is presented in the context of the main stages in the life of a scientist – „Mauritsin”, „Kharkiv”, „Kher-son”, „Kharkiv”, „Petersburg”, „Kharkiv”, „Petersburg” and „Warsaw”. The article highlights only those stages that are provided with sufficient sources and literature. The authors paid special attention to the Kharkiv period of the scientist's life, since this city is associated with the time of study within the walls of the Veterinary Institute, the formation as a scientist and directly scientific and teaching activities. Also, based on the analysis of archival documents from the fund of the Kharkiv Veterinary Institute, stored in the State Archives of the Kharkiv region, it is proved that he had consider-able authority as a scientist and practitioner, since he was involved by government agencies to perform various tasks, and in particular during the First World War and for the development of veterinary medicine in different regions of the state. The memory of Jan Gordzyalkowsky in Kharkiv is immortalized on the pages of the calendar dedicated to out-standing Polish scientists associated with the city, in an open exhibition dedicated to the 170th anniversary of the Kharkiv State Zoological Veterinary Academy and in a memorial plaque, which will be installed on the building of the former Kharkiv Veterinary Institute and dedicated to outstanding Poles, the creators of veterinary medicine in Eastern Ukraine.
Peste des petits ruminants – crucial challenges for the successful disease eradication
Authors: NIEDBALSKI WIESŁAW , FITZNER ANDRZEJ , BULENGER KRZYSZTOF , KĘSY ANDRZEJ
Published: February 2022

Peste des petits ruminants (PPR) is a highly infectious and economically important, viral disease of small ruminants caused by the peste des petits ruminants virus (PPRV), which belongs to the genus Morbilivirus in the family Paramyxoviridae. PPR control is mostly achieved through vaccination and/or slaughter of susceptible animals coupled with clinical or laboratory-based diagnosis. The control and eventual eradication of PPR is now one of the top priorities for the Food and Agriculture Organization (FAO) and the World Organization for Animal Health (OIE). In April 2015, the international community agreed on a global strategy for PPR eradication, setting 2030 as a target date for the elimination of the disease. There is a strong and lasting international consensus to eradicate PPR in order to protect the livelihoods of the world’s poorest populations. There are several crucial challenges to the eradication campaign programme: understanding small ruminant production, facilitating research to support the eradication campaign, improvement of laboratory diagnostics, optimizing vaccine delivery and novel vaccines, improving epidemiological understanding of the virus, defining infection of wildlife and other species, developing better control and animal movement, heightening serological monitoring, understanding socio-economic impact, and garnering funding and political actions.
