Factors Affecting Online Donation Intention in Donation-based Crowdfunding
Authors: Kenang Irantha Hendrika , Gosal Gladys
Published: October 2021

The research aimed to determine the factors affecting online donation intention of Generation Y, particularly in donation-based crowdfunding in Indonesia, because even though online donation had been trending in Indonesia, not all donation projects are successful. Therefore further research was needed to identify factors that influence the success of an online donation project. Using quantitative method, the research used combination of Theory of Planned Behavior (Attitude, Subjective Norms, Perceived Behavioral Control), Social Presence Theory, and S-O-R Theory (Website Quality, Transaction Convenience, Perceived Credibility). The research used purposive sampling with total of 118 respondents. The result of the analysis suggests that millennials’ intention to donate is significantly affected by the perceived credibility of the crowdfunding platform. This is mainly because the transaction is conducted online, hence the donors are concerned about whether their donation is going to be distributed properly. Subsequently, the perceived credibility of crowdfunding platform is significantly affected by social presence, website quality, and transaction convenience, which support previous research related to Social Presence Theory and S-O-R Theory. Meanwhile, attitude, subjective norms, and perceived behavioral control have no significant impact on intention to donate, which may be due to several issues such as trust and security issues considering the donation is conducted through online. The crowdfunding platforms and fundraisers in Indonesia are expected to have guidelines about important aspects that may affect individual’s intention to donate in crowdfunding platform.

Published: October 2021

The research intended to analyze the overreaction phenomenon in Islamic stocks due to COVID-19 as well as the influencing factors by utilizing different test methods and cross-sectional regression. The research employed data on the daily stock prices from August 9th, 2019 to October 26th, 2020 on the Jakarta Islamic Index (JII) and the stocks utilized during the period of events. The sample of this research utilized seven events related to COVID-19. The findings of this research reveals that the announcement of COVID-19 transmission and lockdown (Event 2) causes overreaction in winner stocks. Meanwhile, the overreaction phenomenon of loser stock is due to the announcement of the United States fiscal stimulus (Event 5) and the announcement of the PSBB (Event 6). Furthermore, the new normal announcement event (Event 7) triggers overreaction in the winner and loser stocks. The results indicate that Islamic stocks continue to have several transactions which are prohibited by the Fatwa DSN MUI in the short term. In this case, the variables that impact the overreaction phenomenon are shown to be substantially and negatively linked to leverage and market capitalization, while trading volume significantly influences and has a positive correlation with the overreaction phenomenon.

CONCEPTUALIZATION OF THE CONCEPTS OF “CAREER” AND “CAREER STRATEGIES” IN THE WORKS OF FOREIGN AND DOMESTIC SOCIOLOGISTS
Authors: Kuzmin Viktor Volodymyrovych
Published: October 2021

Problem setting. The development of society is constant. New technologies require the formation of skills that affect both professional and domestic activities of people. Employers seek to select employees who will be interested in their professional activities, which will contribute to the personal development of the individual and will have a positive impact on the work of the enterprise.

            Recent research and publications analysis. In the works of sociologists, the process of self-development of the individual, which contributes to his promotion by professional ladder, is defined as a "career". The analysis of literature sources shows that over time, the interpretation of this concept changes somewhat, acquires new approaches, but its conceptual essence, however, is not definitively defined.

Paper objective. This article aims to define the conceptual meaning of the concepts of “career” and “career strategies” based on the definitions proposed by researchers from different eras.

            Paper main body. The analysis allowed to identify two main conceptual approaches to the concept of “career”, according to which the conceptual essence of career is the individual’s desire for professional self-development, which is reflected in his professional activities, on the one hand, and on the other, life - this is a career, so the standard of living and success directly depend on the level of activity of the individual, his desire to develop.

            Career strategy is a model of behavior that an individual chooses during professional growth. The literature offers many variations of this definition and classification of models of career strategies, but the most complete and generalized is the classification proposed by E. Shane and the conceptual essence of the concept of “career strategy” is reduced to a conscious choice of behavior by the individual both in the professional sphere and in life in general. Sociological research shows that the model of career strategy is a direct reflection of the behavior and lifestyle of the individual in his professional activities, which affects and determines the rate of career growth.

Conclusions of the research. Analysis of scientific publications and scientific works allows to characterize the term “career”, in a conceptual sense, in two perspectives, the first of which is formed on the basis of definitions proposed by the classics of sociology, and characterizes it as a process of professional growth. and from another point of view, which is defined by both foreign and domestic sociologists of the twentieth century, life is a career, it is a continuous movement in a certain direction of professional and personal growth. “Career strategy”, according to the generalized definitions, is a model of an individual's behavior during his movement up the career ladder, which determines the speed of the individual’s development, the ability to succeed in his career and personal life.
POLITICAL CULTURE OF THE MODERN WORLD: EPOCHAL TRANSFORMATIONS
Authors: Polishchuk Ihor Oleksiiovych , Maksimishyna Tetiana Mykolaivna
Published: October 2021

The article is devoted to the topical problem of political and cultural transformations in the interaction between political power and its only source in democratic discourse, the people. This eternal problem of political science and policy is considered in chronological order in the global context and in today’s Ukraine. In traditional societies, there was a remote and alienated coexistence of state institutions and the masses. The exception was the democratic republics of ancient polises. The modern era generates a contractual theory of the origin of the state, which considers the institutions of power as the result of a social agreement between the sovereign people and the governors. In the modern era in the middle of the twentieth century, the concept of the welfare state was formed. In the postmodern era, unstable life forces citizens to behave in relation to state power, depending on the actualization of a particular guise of their own existence. Citizens are losing a clear, unambiguous idea of state power, its functions, place and role in society.
Research on fan vibration fault diagnosis based on image recognition
Authors: Huang Genling , Qiao Lijuan , Khanna Shaweta , Pavlovich Pljonkin Anton , Tiwari Sandeep
Published: October 2021

The conventional methods for vibration fault detection and diagnosis relies on feature extraction from the waveforms of the vibration signals. This article exploits the scope of image recognition application for the detection and diagnosis of fan vibration faults. In this paper, a novel image recognition technique is proposed for vibration-based fault diagnosis using the spectrum images of the vibration signals. 1D vibration signal spectrum is initially computed using Fast Fourier Transform (FFT) and the FFT frequencies are adjusted such that it captures a vibration spectrum diagram as 2D image representation. FFT based vibration analysis is done and the image recognition concept is utilized for feature extraction and a machine learning classification module is used for fault analysis and diagnosis. Effective feature generation is done using Principal Component Analysis (PCA) by removing the redundancy from the feature vectors and machine learning classifiers are used to obtain improved image recognition and classification performance. Artificial Neural Network (ANN) classifier yields better performance in terms of various performance parameters and percentage improvement in terms of accuracy for ANN classification methods over Support Vector Machine (SVM), k-Nearest Neighbours (kNN) and Random Forest Ensemble (RFE) methods are 10.01 %, 4.51 % and 2.01 % respectively. Comparative scenarios are considered in this work for fan vibration fault detection as well as diagnosis based on the image features for various realistic vibration fault conditions. Effectiveness of the proposed image recognition-based technique is compared with the state-of-the-art methods, justifying its outperformance for fan fault detection and diagnosis using the combination of spectrum adjustment, PCA and ANN classification method.

Published: October 2021

The transmission of the high data rate and information over the optical fiber is restricted by various dispersion phenomenon which further results into intersymbol interference (ISI). This article proposes two different methodologies for optical fiber deformation aiding vibration monitoring one using the pin diode as a photo-detector device and another manifesting the avalanche photo-detector. The novelty of this article lies in optical signal conversion using photo-detector processing followed by low pass Gaussian filter in order to reduce the extra contortion. This work is approaching electronic dispersion compensation technique (EDC) for compensation of chromatic dispersion at two distinct bit rates of 25 and 30 Gbps over 120 km of single mode fiber. Both the diodes have tested for theory performance using factors like Q-factor, bit error rate and eye height. It is found that pin diode is exhibiting a quality factor of 67.150 and 40.5944 at 25 and 30 Gbps, respectively. When avalanche pin diode is used at the same data rates, quality factor of 73.0240 and 43.3523 are obtained, respectively. Hence, use of avalanche photodiode at high bit rates is utilized and the simulations showed the optimum photo-diode for efficacious dispersion compensation at such a long transmission distance.

Published: October 2021

Primary detection and removal of mechanical fault is vital for the recovery of mechanical and electrical equipment. The conventional mechanical fault recognition modules are not able obtain highly sensitive feature attributes for mechanical fault classification in the absence of prior knowledge. The fault diagnosis via data-driven methods have become a point of expansion with recent development in smart manufacturing and fault recognition techniques using the concept of deep learning. In this work, a combination of feature selection with Artificial Intelligence (AI) algorithm is presented for the mechanical fault recognition to deal with smart machine tools. This article proposes a CNN based fault recognition and classification framework that uses the combination of feature extraction, feature vector decomposition using Empirical Mode Decomposition (EMD) and deep neural network (DNN) for recognising the different fault states of the rotating machinery. The experimental outcomes obtained by the combination of EMD, feature selection module and Convolutional Neural Network (CNN) provides the detailed fault information by selecting the sensitive features from large number of faulty feature attributes. The proposed fault recognition and classification method performs better in terms of all the parameters yielding 99.01 % accuracy with respective cross-entropy loss of 0.325 and time complexity of 18 mins and 31 seconds. The comparative analysis is also done with other mainstream models and other state of the art methods, which reveals that the maximum improvement of 12.29 % is attained in terms of accuracy for the proposed fault recognition method. The presented method is robust in terms of reduction of network size, improvement of mechanical fault recognition, providing classification accuracy along with high fault diagnostic solution.
Synthesis of sliding control system for automotive suspension under kinematic constraints
Authors: Veselov Gennady , Sinicyn Aleksandr
Published: October 2021

This article is about the problem of control system synthesis for an active suspension system with not-ideal actuator under kinematic constrains. This paper investigates the influence of hysteresis and the dead zone in an actuator on efficiency of an active suspension system. To reduce the influence of hysteresis and the dead zone a method of synthesis of discontinuous control systems is proposed. The proposed discontinuous control system reduces the sensitivity of the system to disturbances caused by a non-ideal actuator. It enables a fourfold expansion of the distribution range where an active suspension is more effective than a passive suspension. This system also takes into account the nonlinear structure of the control object. The efficiency of the closed system is studied on a dynamic model constructed using the Simulink package.

Published: October 2021

Although drone appears in different applications, such as environmental inspection, agriculture or transportation, some aspects require more studies to clarify the efficient outcomes. One of them is to investigate the filtering performance such as Kalman and Complementary filters when the autonomous aerial system (AAS) handles its mission. However, it lacks the systematic research about these filters to provide the proper evaluation. Therefore, in this paper, the research topic related to AAS model to indicate the filtering effects in the agricultural application for making an alternative solution is presented. Firstly, the mathematical representation of system model is established in order to describe the dynamical performance and motion constraints. Then, the theory of filter structure is implemented to estimate the system state. The proposed design is validated in both numerical simulation and experiments. The system parameters that are monitored, include angular values of roll, pitch and yaw in three axes, motion parameters and its trajectories. By utilizing various sensing devices such as gyroscope, accelerometer and compass in real-world hardware, the experimental results could evaluate more precise and efficient design. The findings of this study are to (1) propose the model of AAS and proper filters, (2) launch the verified process and calibration, and (3) demonstrate the competitive performance among filters. From these results of our work, it could be clearly seen that the AAS plays an important role in daily applications and the related topics are still attractive.

Published: October 2021

El caserío, entendido como un paisaje formado por unidades domésticas autónomas distribuidas de manera dispersa, constituye el principal modelo de ocupación del espacio rural en la vertiente atlántica del País Vasco. En las últimas décadas, el estudio arqueológico de muchos caseríos ha permitido definir series tipo-cronológicas de gran detalle para este tipo de edificios. El presente trabajo propone abordar el estudio de los paisajes culturales articulados por el caserío, integrando el estudio de las trazas materiales de los usos agrarios del pasado, como el acondicionamiento de espacios productivos específicos o determinadas prácticas de gestión, con la evolución de las formas arquitectónicas. El análisis se centra en el ejemplo de Zizurkil (Gipuzkoa). Junto con la recopilación de fuentes documentales y orales y el estudio de los elementos arquitectónicos, se ha implementado una metodología geoarqueológica basada en el análisis de diversos parámetros físico-químicos de los suelos de cultivo, con el fin de establecer estratigrafías de alta resolución. Los resultados obtenidos permiten distinguir tres fases en la evolución de este paisaje: un momento de (re)configuración de su estructura básica en los siglos XIV-XIV; una importante intensificación en los siglos XVII-XIX, de la mano de la revolución agraria que siguió a la introducción de cultivos americanos; y una rápida degradación desde mediados del siglo XX.

There is an urgent need to update the science curricula content in light of the Next Generation Science Standards (NGSS). The purpose of this research is to present a proposal of the science curricula content in light of the NGSS. Secondly, the effect of NGSS on conceptual understanding and higher-thinking skills among first-year intermediate students is also analyzed. This work is unique as no research is conducted on the topic as per the best of our knowledge. Hence, the research may motivate further studies on the topic. The semi-experimental method was used to know the impact of teaching science in conceptual understanding and higher thinking skills. The sample consisted of 62 students divided into two groups. The control group was led the “nature of material” unit in the first-year intermediate book, issued by the Ministry of Education in 1438 AH. A list of science tools was prepared for analyzing the content of science curricula in light of Next-Generation Science Standards (NGSS). Two tests were prepared, a conceptual understanding test and a higher thinking skills test. The research revealed different results: the availability degree of science for the next-generation science standards curricula in the intermediate stage was low. The developed unit’s size effect in light of these standards on conceptual understanding and higher-thinking skills among the research sample was high with a value of 0.89-0.91.

Published: October 2021

Background

Vision impairments (VIs) and blindness are major global public health issues. A visual acuity (VA) test is one of the most crucial standard psychophysical tests of visual function and has been widely used in a broad range of health care domains, especially in many clinical settings. In recent years, there has been increasing research on mobile app–based VA assessment designed to allow people to test their VA at any time and any location.

Objective

The goal of the review was to assess the accuracy and reliability of using mobile VA measurement apps.

Methods

We searched PubMed, Embase, Cochrane Library, and Google Scholar for relevant articles on mobile apps for VA assessment published between January 1, 2008, and July 1, 2020. Two researchers independently inspected and selected relevant studies. Eventually, we included 22 studies that assessed tablet or smartphone apps for VA measurement. We then analyzed sensitivity, specificity, and accuracy in the 6 papers we found through a meta-analysis.

Results

Most of the 22 selected studies can be considered of high quality based on the Quality Assessment of Diagnostic Accuracy Studies–2. In a meta-analysis of 6 studies involving 24,284 participants, we categorized the studies based on the age groups of the study participants (ie, aged 3-5 years, aged 6-22 years, and aged 55 years and older), examiner (ie, professional and nonprofessional examiners), and the type of mobile devices (ie, smartphone, iPad). In the group aged 3 to 5 years, the pooled sensitivity for VA app tests versus clinical VA tests was 0.87 (95% CI 0.79-0.93; P=.39), and the pooled specificity was 0.78 (95% CI 0.70-0.85; P=.37). In the group aged 6 to 22 years, the pooled sensitivity for VA app tests versus clinical VA tests was 0.86 (95% CI 0.84-0.87; P<.001), and the pooled specificity for VA app tests versus clinical VA tests was 0.91 (95% CI 0.90-0.91; P=.27). In the group aged 55 years and older, the pooled sensitivity for VA app tests versus clinical VA tests was 0.85 (95% CI 0.55-0.98), and the pooled specificity for VA app tests versus clinical VA tests was 0.98 (95% CI 0.95-0.99). We found that the nonprofessional examiner group (AUC 0.93) had higher accuracy than the professional examiner group (AUC 0.87). In the iPad-based group, the pooled sensitivity for VA app tests versus clinical VA tests was 0.86, and the pooled specificity was 0.79. In the smartphone-based group, the pooled sensitivity for VA app tests versus clinical VA tests was 0.86 (P<.001), and the pooled specificity for VA app tests versus clinical VA tests was 0.91 (P<.001).

Conclusions

In this study, we conducted a comprehensive review of the research on existing mobile apps for VA tests to investigate their diagnostic value and limitations. Evidence gained from this study suggests that mobile app–based VA tests can be useful for on-demand VI detection.

Smartphone Alcohol Use Disorder Recovery Apps: Cross-sectional Survey of Behavioral Intention to Use (Preprint)
Authors: Menon Rijuta , Meyer Julien , Nippak Pria , Begum Housne
Published: October 2021

BACKGROUND

Alcohol use disorder (AUD) carries a huge health and economic cost to society. Effective interventions exist but numerous challenges limit their adoption, especially in a pandemic context. AUD recovery apps (AUDRA) have emerged as a potential complement to in-person interventions. They are easy to access and show promising results in terms of efficacy. However, they rely on individual adoption decisions and remain underused.

OBJECTIVE

The aim of this survey study is to explore the beliefs that determine the intention to use AUDRA.

METHODS

We conducted a cross-sectional survey study of people with AUD. We used the Unified Theory of Acceptance and Use of Technology, which predicts use and behavioral intention to use based on performance expectancy, effort expectancy, social influence, and facilitating conditions. Participants were recruited directly from 2 sources; first, respondents at addiction treatment facilities in Ontario, Canada, were contacted in person, and they filled a paper form; second, members from AUD recovery support groups on social media were contacted and invited to fill an internet-based survey. The survey was conducted between October 2019 and June 2020.

RESULTS

The final sample comprised 159 participants (124 involved in the web-based survey and 35 in the paper-based survey) self-identifying somewhat or very much with AUD. Most participants (n=136, 85.5%) were aware of AUDRA and those participants scored higher on performance expectancy, effort expectancy, and social influence. Overall, the model explains 35.4% of the variance in the behavioral intention to use AUDRA and 11.1% of the variance in use. Social influence (P=.31), especially for women (P=.23), and effort expectancy (P=.25) were key antecedents of behavioral intention. Facilitating conditions were not significant overall but were moderated by age (P=.23), suggesting that it matters for older participants. Performance expectancy did not predict behavioral intention, which is unlike many other technologies but confirms other findings associated with mobile health (mHealth). Open-ended questions suggest that privacy concerns may significantly influence the use of AUDRA.

CONCLUSIONS

This study suggests that unlike many other technologies, the adoption of AUDRA is not mainly determined by utilitarian factors such as performance expectancy. Rather, effort expectancy and social influence play a key role in determining the intention to use AUDRA.

Published: October 2021

BACKGROUND

The prolonged COVID-19 pandemic has affected mental health among workers. Psychoeducational intervention via a website could be effective for primary prevention of mental illness among workers in the current COVID-19 pandemic.

OBJECTIVE

The aim of this randomized controlled trial is to examine the effect of a newly developed online psychoeducational website named Imacoco Care on reducing psychological distress and fear about COVID-19 infection among workers.

METHODS

Participants in the study were recruited from registered members of a web survey company in Japan. Participants who fulfilled the eligibility criteria were randomly allocated to the intervention or control group. Participants in the intervention group were invited to access the Imacoco Care program within a month after the baseline survey. The Kessler Psychological Distress Scale (K6) and the Fear of COVID-19 Scale (FCV-19S) scores were obtained at baseline and at 1- and 3-month follow-ups.

RESULTS

A total of 1200 workers were randomly allocated to the intervention and control groups (n=600 [50%] per group). The Imacoco Care intervention group showed a significant favorable effect on K6 scores (P=.03) with a small effect size (ES; Cohen d=–0.14) and an adverse effect on FCV-19S scores (P=.01) with a small ES (Cohen d=0.16) at 3-month follow-up. In the per protocol analysis (including only participants who had read the Imacoco Care content at least 1 time), the Imacoco Care intervention group also showed a significant favorable effect on reducing K6 scores (P=.03), while an adverse effect on FCV-19S scores was not significant (P=.06) in the intervention group at 3-month follow-up.

CONCLUSIONS

A web-based psychoeducation approach may be effective for improving psychological distress among workers; however, it may be important not only to distribute information but also to encourage active engagement with the content of the program to prevent adverse effects of psychoeducational intervention.

To study fungal infections such as Mucormycosis, Aspergillosis, Candidiasis, Cryptococcosis associated with Covid-19.
A detailed study was done with the information gathered from the articles in specified databases, online sources, and online published materials to have current details of the situation of fungal infections in covid patients.
Fungal infections were seen among covid-19 patients mostly due to opportunistic fungal pathogens such as Mucor, Candida, Aspergillus, and Cryptococcus. The reason behind rising opportunistic fungal infections among covid-19 patients may be the immunocompromised host. The most common species responsible for fungal infections in covid-19 were noticed to be of genus Mucor, A. flavus, and A. fumigatus species of genus Aspergillus, C. albicans species of genus Candida, C. neoformans, and C. gattii species of genus Cryptococcus.
Patients suffering or recovered from covid-19 are now facing numerous Secondary Infections. The majority of secondary infections associated with covid-19 are Fungal Infections. Mucormycosis, candidiasis, aspergillosis, cryptococcosis as opportunistic infections are seen widely in the covid-19 treated patients. Rapid progression of such fungal infections is required to be controlled by early diagnosis of infection and by identifying the underlying risk parameters. Protocols for disease management will be beneficial too.
Building the Symbolic Space of the Political World Map in Russian Collective Consciousness
Authors: Smul'kina Natal'ya
Published: October 2021

The paper describes the major models of building symbolic spaces of the world maps in the Russian collective consciousness and provides the classification of the factors to build symbolic representations. The author considers the potential risks associated with shaping unfavourable symbolic outlines in the representations of the political world map with respect to each model. Risks were primarily related to the negative impact of anxiety on the level of collective attitudes; the symbolic voidness of images of certain countries; negative attitudes towards the international order; the conflicted or, conversely, idealized viewpoint on the entire international (foreign) affairs; the transformation of russocentrism into the image of confrontation between ‘us’ and ‘them’ in the context of the insufficiently built national-state identity and passive dissatisfaction; the stereotyped, often cognitively shallow and ‘mosaic’ perception of own country by Russian youth.

The symbolic ideas of both possible and desirable international trends in Russian collective consciousness can be described as fragmented, which can probably be due to the inadequate completeness of the symbolic space of the political world map. The vague ideas by Russians regarding the country’s place in the world and its possible behaviour strategies in international politics make foreign policy perception hypersensitive and dependent primarily on stereotypes and the media’s informational agenda, which is also a risk.

Following the study outcomes, a set of socio-political mechanisms and measures that can prevent and minimize the identified challenges and the risks was proposed. The need to frame an elaborate and consistent information policy (through media, cultural, educational and youth policy, educational system, non-profit institutions) aimed at minimizing the symbolic voidness of the world map perceived by Russian citizens, at building the national-state identity and forming symbolically complete images of own territory and those of other countries as well as at systematic and adequate informing citizens about current international events and contacts through dialogs is of major importance.

Published: October 2021

Abstract: Turbo coded Orthogonal Frequency Division Multiplexing (OFDM) is attractive technique for high data rate in wireless communication applications, mobile communications (4G) and Wireless Metropolitan Area Networks (WMAN) and Digital Video Broadcasting (DVB). The performance of TURBO Coded 16 QAM and 64 QAM schemes with OFDM for high speed data rate applications is compared which is used in digital video broadcasting. BER analysis is used to assess the system's performance. Due to the high data rate of 64 QAM, attaining BER of ૚૙ି૝ requires Eb/No of 0.9 dB in 16QAM, whereas obtaining BER of ૚૙ି૝ requires 0.17 dB in 64QAM. By using OFDM removes Inter Symbol Interference (ISI) and Adjacent Channel Interference (ACI). Keywords: Wireless communication, mobile communication, OFDM, QAM, TURBO Encoding

PROPOSAL OF A MODEL FOR THE ECO-INNOVATION INTEGRATION INTO THE INNOVATION PROCESS OF COMPANIES IN SLOVAKIA TO INCREASE THEIR PERFORMANCE
Authors: Loučanová Erika , Olšiaková Miriam
Published: October 2021

The issue of innovations, as well as ecological innovations, is a concept in Slovakia, to which considerable attention is paid because they affect all spheres of society. They relate to production, logistics, sales, and the consumers, who decide on their acceptance on the market. However, the success of innovation in the market depends on several factors that influence the innovation process. They are not just determinants that act pro-innovation and thus support innovation and innovation process. In the innovation process, some factors have the opposite effect and result in forces that suppress the creation of innovation. Therefore, in this article, we focus on mapping the state of pros and cons of innovation forces acting on companies’ innovation process in Slovakia. Based on the above findings, we have identified a large interest in implementing innovations, using an open innovation system to implement innovations and implementing eco-innovation. On the other hand, we have also identified negative factors influencing companies’ innovation process such as lack of financial resources, high bureaucracy, lack of relevant information for creating innovations, low awareness of eco-innovation, etc. Subsequently, based on the findings, we proposed a model for eco-innovation integration into companies’ innovation process in Slovakia, which was the paper’s aim. The proposed model eliminates mainly the negative influencing factors of the innovation process in companies, and at the same time, it should support them for the innovation direction. Implementing the proposed model should lead to an innovation increase in companies, but their positive impact also applies to environmental support and an overall increase in the company´s efficiency in Slovakia.
APPLICATION OF PHYSICAL INTERNET IN INTRALOGISTICS – A SIMULATION STUDY
Authors: Puskás Eszter , Bohács Gábor , Zakariás Levente

One of the biggest challenges today is to make traditional systems more sustainable. Physical Internet (PI, π) based logistics systems provide one of the most defining solutions. In our opinion, it is worthwhile to deal with the intralogistics conversion of the Physical Internet because traditional systems can no longer operate with sufficient efficiency to meet growing customer expectations and demands. This research focuses on restructuring a factory from its traditional operating to a PI-based system using our previously defined intralogistics components. The article surveys the possibility of creating PI-hub and virtual PI-hub in a factory process. The warehouses were converted to PI-hubs, and virtual PI-hubs were placed near the two manufacturing to create a more flexible structure. We created a simulation study in AnyLogic where we examine the efficiency achievable by automated guided vehicles (AGVs) in a PI-based system. The results were compared based on the traditional and PI-based systems. Based on the simulation the inefficiency of the PI-based system is lower (by ~18%) at higher control event values. This allows achieving a more efficient, flexible, sustainable, and balanced operation.

Suvarnabhumi Airport is a gateway to Thailand and Asia. It attracts inbound-, outbound- and transit passengers. The objectives of this study were to develop an airport service quality, image and perceived value framework for the loyalty of passengers and to study the direct, indirect and total effects of the factors that influence the loyalty of passengers who used the service at Suvarnabhumi Airport. This quantitative research method uses the questionnaire as a tool for collecting data from 400 passenger samples. According to the Structural Equation Modelling analysis, airport service quality, image and perceived value have had a positive effect on loyalty that airport service quality mainly has an impact on passenger loyalty. There are four latent dimensions of airport service quality, namely, essential services; comfort, convenience and enjoyment; security, customs and passport control; and special facilities, that can help develop loyalty. Perceived value and image on airport administration and management had a significant direct effect to passenger loyalty. Improving these facotrs in order to attract passenger interest and attention can lead to the development of airport organization performance, and to increase competitiveness as an aviation hub in this region.

Published: October 2021

Background and Objectives: Transitioning from medical school to residency is challenging, especially in rural training programs where a comprehensive scope of practice is needed to address rural health disparities. Oregon Health & Science University partnered with Cascades East Family Medicine Residency in Klamath Falls, Oregon to create an integrated fourth-year medical student experience (Oregon Family medicine Integrated Rural Student Training (Oregon FIRST). Participants may then enter this residency to complete their training with the intention to practice in rural underresourced settings. 
Methods: In this exploratory study, we conducted key informant interviews with 9 of ten Oregon FIRST participants to determine how Oregon FIRST contributed both to their readiness for residency training and their choice to practice in rural underserved locations. Interviews were conducted between June 10, 2020 and July 8, 2020. We analyzed field notes taken during interviews for emergent themes using classical content analysis.
Results: Emergent themes included logistical ease, relationship development, key curricular elements, and commitment to rural practice. Overwhelmingly, Oregon FIRST participants reported the experience had many challenging and demanding components because they served as subinterns for their entire fourth year of medical school, but this prepared them very well for internship. When asked if they would choose to enroll in Oregon FIRST again, given what they now know about physician training and patient care, all nine (100%) said they would.
Conclusions: This study demonstrated that Oregon FIRST students felt better prepared for the rigors of residency and are committed to practicing in rural areas.
