Abstract

COVID-19 is a very dangerous respiratory disease that can spread quickly through the air. Doctors, nurses, and medical personnel need protective clothing and are very careful in treating COVID-19 patients to avoid getting infected with the COVID-19 virus. Hence, a medical telepresence robot, which resembles a humanoid robot, is necessary to treat COVID-19 patients. The proposed self-balancing COVID-19 medical telepresence robot is a medical robot that handles COVID-19 patients, which resembles a stand-alone humanoid soccer robot with two wheels that can maneuver freely in hospital hallways. The proposed robot design has some control problems; it requires steady body positioning and is subjected to disturbance. A control method that functions to find the stability value such that the system response can reach the set-point is required to control the robot's stability and repel disturbances; this is known as disturbance rejection control. This study aimed to control the robot using a combination of Proportional-Integral-Derivative (PID) control and a Kalman filter. Mathematical equations were required to obtain a model of the robot's characteristics. The state-space model was derived from the self-balancing robot's mathematical equation. Since a PID control technique was used to keep the robot balanced, this state-space model was converted into a transfer function model. The second Ziegler-Nichols's rule oscillation method was used to tune the PID parameters. The values of the amplifier constants obtained were Kp=31.002, Ki=5.167, and Kd=125.992128. The robot was designed to be able to maintain its balance for more than one hour by using constant tuning, even when an external disturbance is applied to it. Doi: 10.28991/esj-2021-SP1-016 Full Text: PDF

Abstract

Because of their mortality rate, diabetes and COVID-19 are serious diseases. Moreover, people with diabetes are at a higher risk of developing COVID-19 complications. This article therefore proposes a single, non-invasive system that can help people with diabetes and COVID-19 to monitor their health parameters by measuring oxygen saturation (SPO2), heart rate, and body temperature. This is in contrast to other pulse oximeters and previous work reported in the literature. A Max30102 sensor, consisting of two light-emitting diodes (LEDs), can serve as a transmission spectrum to enable three synchronous parameter measurements. Hence, the Max30102 sensor facilitates identification of the relationship between COVID-19 and diabetes in a cost-effective manner. Fifty subjects (20 healthy, 20 diabetic, and 10 with COVID-19), aged 18-61 years, were recruited to provide data on heart rate, body temperature, and oxygen saturation, measured in a variety of activities and scenarios. The results showed accuracy of ±97% for heart rate, ±98% for body temperature, and ±99% for oxygen saturation with an enhanced time efficiency of 5-7 seconds in contrast to a commercialized pulse oximeter, which took 10-12 seconds. The results were then compared with those of commercially available pulse oximetry (Oxitech Pulse Oximeter) and a thermometer (Medisana Infrared Thermometer). These results revealed that uncontrolled diabetes can be as dangerous as COVID-19 in terms of high resting heart rate and low oxygen saturation. Doi: 10.28991/esj-2022-SPER-04 Full Text: PDF

Abstract

The Covid-19 pandemic delayed the ratification of several internal laws, reforms, and amendments, especially in developing countries such as Thailand, resulting in limited human rights for the populations. There is a unique violation of human rights inclusive of the right to life, the right not to be tortured, the right to liberty and safety of persons which are very important to international and civil society. This research explores the enforcement measures of the International Convention for the Protection of All Persons from Enforced Disappearance (CED). Thailand is currently in the process of ratifying its membership in CED. This ratification process will contribute towards Thailand for holding an important position to fulfill its obligations as a State Party member of this Convention. Thailand has been drafting internal laws and regulations to be consistent with the CED to recognize and protect lawful human rights. People must not be forced to disappear because such action is a serious criminal offence that must be punished appropriately under the CED. In addition, the injured persons shall be treated fairly and equally in accordance with the objectives and purpose of CED, and the Member of Parliament (MP) shall legislate and support the enactment in accordance with the Convention's obligations. In accordance with international mechanisms, these measures will further enhance the promotion and protection of Thailand's human rights. Therefore, Thailand should complete the ratification process at the earliest to develop more efficient domestic legal measures and mechanisms. Similarly, ratification would be consistent with Article 16 of the Sustainable Development Goals (SDGs), which will contribute to security and enhance a peaceful society by providing access to justice to all people in Thailand. Doi: 10.28991/esj-2022-SPER-05 Full Text: PDF

Abstract

This study reveals the approach to scaling socio-economic indicators to ensure economic security through regional budget expenditures to the GRP ratio example. Indicator choice is conditioned by the necessity to determine the degree of the federal center's rational influence on the regional strategic goals of sustainable development. The study aims to develop and test the system for assessing the dynamics of Russian socio-economic development based on the authors' interpretation of the scaling factor values. The main research method is scaling, which provides additional perspectives reflected by preserving proportions when changing the target parameters. The new method's effectiveness is confirmed by calculating the scaling factor. Its value interpretation gives a tool for assessing the effectiveness of the strategy development system and its economic security. The study's relevance is due to adaptation to global transformations based on the management system's capability to act under various crisis scenarios and make anti-crisis decisions important for the Russian economy. The findings improve the basis for implementing a sustainable strategic planning system and strengthening national security in the COVID-19 pandemic. The findings make it possible to predict the further evolution of the relationships between indicator groups in order to increase the role of per capita budgetary expenditures in GRP. Doi: 10.28991/esj-2022-SPER-08 Full Text: PDF

Abstract

In Vietnam, the Covid-19 pandemic has taken place since the beginning of 2020, has seriously impacted businesses' production and business activities, and pushed the world economy into recession. Like other countries globally, Vietnam has been severely affected by this global pandemic. During the Covid-19 outbreak, small and medium enterprises (SMEs) that stopped production or went bankrupt increased. Besides, due to the deep integration into the global value chain now closed to the port, the findings explored that SMEs with a larger scale faced many difficulties. The number of enterprises having to shrink production also increased rapidly. Most businesses say the Covid-19 outbreak has negatively affected their production and trade. The primary official data is distributed directly to business leaders through detailed questionnaires to collect preliminary data and selected models by a simple random process. SMEs failed to reach customers, broke the supply chain, revenue plummeted, and laid off many workers, so far struggling. The study objectives found that more than 87% of businesses are affected by Covid-19. Therefore, the article novelty had several recommendations for enhancing the competitive capacity of small and medium enterprises in Vietnam after the Covid-19 pandemic. Doi: 10.28991/esj-2022-SPER-09 Full Text: PDF

Abstract

Problem-solving skill is one of the soft skills that has become essential for employees in various organizations. Training model and educational technology were considered key success factors in delivering knowledge for personnel in the workplace to develop this skill. Problem-Based Learning (PBL) is a key driver for learning activities, which has been increasingly adopted for workplace training and has proven to be one of the best approaches to helping learners improve their problem-solving skills in the organization. Hence, this research aims to synthesize problem-based blended training via chatbot to enhance problem-solving skills in the workplace. Literature review, document analysis, and focus group technique were used as the main procedures for the first phase of model synthesis. The effectiveness of the training model was examined in the second phase by applying it to 20 employees of the flexible lamination manufacturers in Thailand from purposive sampling. The training was held for four weeks and examined with a problem-solving skill test. In addition, a follow-up test has been conducted to monitor retention skills after a four-week training period. Data analysis used the repeated-measures ANOVA test with normality and homogeneity as a prerequisite test. This study shows that the problem-based blended training model via chatbot to enhance problem-solving skills in the workplace comprises six main steps: (1) Group identification; (2) Problem identification; (3) Idea creation; (4) Learning; (5) Implementation; (6) Evaluation. The results on the implemented training model showed that problem-solving skills after training were significantly higher than those before training, and the retention of skill remained higher than that before training and did not significantly change after finishing training at a statistical significance of 0.5. As a result, the developed model is highly appropriate for implementation, particularly because the chatbot platform is involved in almost every step of this training model to accommodate learners who can easily access the training platform, repeat the training content, and feel motivated to explore new information to improve their problem-solving skills. In a post-COVID-19 period with distancing required in the workplace, this model is applicable to deliver efficiency in workplace training. Doi: 10.28991/ESJ-2022-SIED-01 Full Text: PDF

Abstract

During the COVID-19 pandemic, the application of e-payment has rapidly increased. However, e-payment has not been able to achieve a trustworthy level in e-commerce transactions. Thus, cash payment methods with Cash On Delivery (COD) services still dominate C2C e-commerce payment transactions in Indonesia. This study aims to investigate factors that affect users' switching intentions from COD to e-payment services. The research model was adopted by using the Push-Pull-Mooring framework, integrating perceived COVID-19 risk, technology acceptance, and transaction effort. Empirical research was conducted using data from 546 COD and e-payment users in Indonesia, with Structural Equation Modelling (SEM) being used to validate the model and analyze the hypotheses. The results indicate that switching intention from COD to e-payment is significantly influenced by pull factors in e-payment, which are economic benefits, performance expectancy, effort expectancy, and critical mass. There are also two mooring factors that significantly influence the switching intention from COD to e-payment, which are trust and perceived security and privacy. This study makes a significant contribution to the literature in terms of validating a theoretical framework that emphasizes factors that influence user switching intentions from COD to e-payment in the context of the COVID-19 pandemic. This research can be a reference for Indonesian payment system regulators and e-payment service providers in formulating regulations and strategies to accelerate the spread of digital transactions in Indonesia. Doi: 10.28991/esj-2022-SPER-010 Full Text: PDF

Abstract

The COVID-19 pandemic brought CDTs to the forefront of business life. This study provides an important insight into a specific country's context, which has not been sufficiently investigated. This paper aims 1) to investigate how companies' general characteristics impact the use of contactless digital technologies (CDTs) in Hungary; 2) to examine employees' attitudes regarding the use of CDTs; and 3) to explore how firms have tried to enhance employees' acceptance of CDTs. A computer-assisted data collection (CAPI) was carried out during the coronavirus (COVID-19) period. The online questionnaire was completed by employees of Hungarian companies. Descriptive statistics and relationship analyses (Cramer's V and Kendall's Tau) were used to analyse the collected data ( ). Results indicate that 1) the general characteristics of companies, such as their profile and size, have a significant impact on the use of CDTs; 2) the typical attitude of employees towards CDTs is rather positive; and 3) the acceptance of the use of CDTs can be supported by practical rather than theoretical solutions. The result can add value and stimulate new research related to the usage of CDTs, potentially serving as a useful benchmark for other countries. Doi: 10.28991/esj-2022-SPER-015 Full Text: PDF

Abstract

In the study, an overview of the current situation in the field of inclusive education in Slovakia is presented. Since teachers' attitudes towards inclusive education are among the key determinants of the success or failure of SEN students' inclusion in mainstream schools, the main objective of the study was to investigate them in the context of implementing the new Strategy for Inclusive Education in Slovakia. In this quantitative study, Mahat [1] "The Multidimensional Attitudes Toward Inclusive Education Scale (MATIES)" was used and three components of teachers' attitudes – cognitive, affective, and behavioral – were examined by means of univariate, bivariate, and multivariate methods of statistical analysis. As the aging of the teaching population is an issue in Slovakia, age-related peculiarities were focused on in the study. The findings revealed statistically significant differences in the affective and behavioral components between the two examined age-groups of teachers. Since no extensive study has been focused on teachers' attitudes towards replacing school integration by school inclusion in Slovakia, the proposed study aims to fill the gap and provide unique data useful in the process of changing traditional schools into inclusive ones. The obtained results also point to the importance of considering teachers' attitudes towards any changes to be introduced. Doi: 10.28991/ESJ-2022-SIED-02 Full Text: PDF

Abstract

The paper deals with two topics: Participatory Budgeting (PB) and mayoral impact on its success. Its theoretical background is rooted in the interrelation of the discourse of PB and characteristics of mayors as city leaders. The paper analyzes articles revealing personal, social and political characteristics of mayors and their impact on civic governance. The scope of collected characteristics was researched with a view on how they impact succession and the resilience of PB. The idea behind this analysis was not only to reveal mayoral characteristics and their impact on PB in general, but to test them against the background of the Covid-19 pandemic as an example of an external crisis. PB practice in Lithuanian municipalities was researched. Qualitative semi-structured interviews were conducted with mayors or their subordinates and helped to reveal the mayors' role and impact on PB resiliency. Relevant statistical data was collected and analyzed in order to obtain the specific characteristics. The results proved the impact of mayors' social and personal backgrounds on PB resiliency, but during challenging times or even crises, political affiliation, interrelation with the council or administrative and political skills are supportive factors. The paper suggests that mayors cannot ensure the persistence of PB alone when finances are scarce during times of crisis. Doi: 10.28991/esj-2022-SPER-011 Full Text: PDF
