Inbound and Outbound Tourism in China: A Perspective Article
91-107Megtekintések száma:312The tourism industry in China has undergone significant changes due to globalization, technology, and changing consumer preferences. This perspective article, based on a systematic literature review, examines examines trends, challenges, and opportunities in inbound and outbound tourism in China, focusing on the industry's dynamism. Both inbound and outbound tourism have been negatively impacted by the COVID-19 pandemic, which has prompted new strategies and environmental adaptations. China has changed its priorities within the country to encourage domestic travel and support local firms. The rise in internationalisation and the growing middle class in China have led to an unprecedented rise in outbound travel. Chinese travellers are affecting travel habits and spending all around the world in the tourism sector. Language barriers, cultural differences, and safety concerns are some of the challenges that come with travelling abroad.

Improving Safety & Ride Comfort through Dual Suspension System in Road Vehicles
30-36Megtekintések száma:180The essential objective of the proposed suspension framework is to limit the undesired disturbance of a vehicle because of uneven surfaces on streets. This framework in vehicles is comprise of some fundamental components like dampers and springs which ingests the stuns that are instigated by unusual streets. In any case, these frameworks can just work up to a predefined constrain. Vehicle suspension frameworks are planned by taking the solace capacity of a traveler in record and to enhance the street grasp on each surface.
This examination proposes an idea for structuring a superior suspension arrangement of vehicles to upgrade the nature of the drive without corrupting the dependability of the vehicle plan. In this exploration, a mix of two suspension framework is presented in which one goes about as an essential suspension while different fills in as an optional framework that can adequately lessen the vibrations. This mix upgrades the customary framework that is right now introduced in vehicles without bargaining on solace and street hold.

The Dunning–Kruger Effect in Knowledge Management Examination of BSc Level Business Students
14-21Megtekintések száma:208The Dunning-Kruger effect (DKE) in higher education evaluation is one of the current research areas of psychology, educational science, and management science (in our case). Its importance is that the less prepared one is, the less accurately one can judge what performance is expected of him. What is more, he will err more and will overestimate himself. The present study aims better to understand the phenomenon with new, small-sample empirical results. The study is part of a research series that has been ongoing at the University of Debrecen since 2015. It not only quantitatively expands the literature but also includes the course of Knowledge Management among those examined. During the research, students were asked both before the examination (N = 63) and after the examination (N = 76) to guess how many points they would achieve on a multiple-choice test. It supports the presence of DKE, both in the case of pre-examination and post-examination self-evaluations. Using four multivariate linear regression models, we examined whether the sign value or absolute value of the errors made during the guesses show a correlation - in addition to the available control variables - with the test score. Our results showed that the more accurate the pre-examination and post-examination estimations were, the higher the students' actual score was, while the less they tended to overestimate their preparation. This supports the presence of DKE, both in the case of pre-exam and post-exam self-evaluation.

Generative Design of Articulated Rod of Radial Engine
36-47Megtekintések száma:446The constant need for improvement drives humans to look for the best possible option in every field. Computer Aided Design (CAD) is no exception, to follow the best method of designing a product and finalizing it, researchers came up with an idea to generate multiple designs using fixed input values and finalizing the most appropriate one. The objective is achieved using an iterative design process based on algorithms by a specific software. Generative design introduces a new experience based on the Integration of machine dynamics in the manufacturing of objects and about experience. In this work generative design method was investigated on an articulated rod, one of the most important components of the rotary engine, to effectively improve the overall working performance of the engine and enhance its performance by decreasing its mass. Since fuel consumption by the machine can be greatly reduced by lowering the mass, so the goal is to minimize the weight of the rod while mechanical characteristics have to be within the acceptable values.

Viselhető technológia használat a Debreceni Egyetem hallgatói körében
33-47Megtekintések száma:136Világszerte sürgető közegészségügyi probléma a fizikai aktivitás hiánya, az ülő életmód széleskörű elterjedése. A probléma jellemző a fiatal populációra is, kiemelten az egyetemistákra, akik idejük jelentős részét töltik üléssel. A technológiai fejlődés egyik katalizátora a mozgásszegény életmód térnyerésének, ugyanakkor ennek köszönhetően számos olyan eszköz jelent meg a piacon, mely éppen a fizikai aktivitás ösztönzésére is szolgálhat. Folyamatosan növekvő tendenciát mutat a fizikai aktivitást mérő viselhető technológiai eszközök – karóra, karpánt – elterjedése a lakosság körében, mellyel párhuzamosan növekszik a magunkról gyűjtött adatok (lépésszám, elégetett kalória, pulzus) mennyisége is. A szerzők témaválasztását az indokolja, hogy a hazai sporttudomány területén kevés olyan tanulmánnyal találkozhatunk, mely napjaink korszerű információtechnológia eszközeit helyezi a fókuszába a fizikai aktivitás dimenziójában. Jelen tanulmány célja, hogy az egyetemista populáció körében felmérje az aktivitást mérő viselhető eszközökkel kapcsolatos attitűdöket. Keresztmetszeti kutatásunk során online kvantitatív kérdőíves felmérést végeztünk a DE GTK hallgatói körében. A kérdőívet 340 fő töltötte ki megfelelően. A leíró statisztika mellett az összefüggések vizsgálatakor paraméteres és nem paraméteres próbákat alkalmaztunk (Pearson-féle khí négyszet próba, Fisher féle egzakt próba, t-próba). A statisztikai próbák eredményeit p<0,05 esetén tekintettük szignifikánsnak. Kolgomorov-Smirnov teszttel vizsgáltuk a változók eloszlását. A megkérdezettek többsége (55%) kipróbált már valamilyen viselhető, fizikai aktivitást mérő eszközt. Harmaduk (34%) jelenleg is használja az eszközét. Akik eddig nem próbálták ki ezeket az eszközöket az árat jelölték meg elsődleges visszatartó tényezőként. Harmaduk tervezi, hogy beruház egy ilyen eszközre a jövőben. Az eszközt használók 39%-a aktivitásmérő karkötőt, míg 61%-uk okosórát használ, vagy használt korábban. Nemek tekintetében nem találtunk eltérést az eszközök tulajdonlását tekintve. A megkérdezett aktivitást mérő eszközt viselő fiatalok 66,8%-nak a fizikai aktivitásának követése volt az elsődleges célja. A leggyakrabban használt funkció a lépésszám követése volt, a megkérdezettek 81%-a jelölte, ezt követte a pulzusszám mérése (67%). Legtöbben a lépésszámukkal kapcsolatban (69%) határoztak meg valamilyen célkitűzést. Minden harmadik hallgató szerint az eszköz hatására többet mozgott és sikerült fenntartania az emelt mozgás szintjét. A hallgatók 44%-a állította, hogy a fizikai aktivitása nem változott az eszköz használatának ellenére sem. A megkérdezettek inkább nem értenek egyet a felsorolt pozitív élettani hatásokkal az eszközök viselésével kapcsolatban. Kutatásunkban is érezhető, hogy a viselhető eszközök hatással vannak a fiatalokra, nyomonkövetik saját adataikat ugyanakkor megkérdőjelezhető, hogy az eszközök önmagukban elég ösztönző hatásúak-e a hallgatók számára az egészségesebb életmód kialakításában.

Analysis of Disinfection Technologies that can Increase the Efficiency of Indoor Logistics Processes, which has been Reduced due to the COVID Pandemic
62-71Megtekintések száma:157As a result of the Coronavirus, both supply chain and internal logistics processes at factories have changed a lot. In many areas, the effectiveness of the logistics processes has declined because of the restrictions implemented against the virus. The study lists some adverse effects where logistics processes had to be modified due to the changing and protection measures against or negative effects of the virus. The authors also argue that these restrictions decreased the efficiency of logistics processes and workers' productivity. One option to increase the logistics sector's efficiency is to use air purification technologies, like the ones studied in this paper: UV-C, Bioxygen® or plasma-ion decontamination technologies. These disinfection processes can create a safe indoor environment. The authors analyse the examined technologies with SWOT analysis. The analysis results demonstrate which disinfection application is the most beneficial to help in improving indoor air quality for logistics processes.

Was UEFA’S Goal of an Environmentally Friendly Euro 2020/21 a Success?
152-164Megtekintések száma:570The football Euro 2020/21 has been said to be more environmentally friendly, as it was spread all over Europe, thus no new stadiums needed to be built. On the other hand, more traveling became necessary. How does these effects behave with each other? Was the attempt to reduce emissions successful?
This paper seeks to compare the goals for UEFA 2020/21 for environmental friendliness and its success. A mixed research strategy was adopted in this paper where qualitative analysis was done on existing literature review and also quantitative approach where assumptions were drawn from literature review to estimate the environmental impact. This paper found that UEFA's initial estimate of 425,000 tons of carbon dioxide emissions in traveling for the Euro Cup 2020 was a bit higher than the actual amount of carbon emissions from our calculation of 143,531 tons. What stands out is that its findings agree with UEFA's estimate that Euro Cup 2020 emissions were lower than that of 2016 which emitted 517,000 tons of carbon dioxide for traveling. This gives a greater reason to conclude that UEFA met its goal of reducing carbon emissions. The overall carbon dioxide emissions in traveling and constructing stages were 1,275,988 tons in Euro Cup 2020 and 2,803,000 tons in Euro Cup 2016. This further affirms the overall carbon dioxide emission reduction by half in Euro Cup 2020 as compared to Euro 2016. From our findings, we can conclude that the Euro Cup 2020 indeed succeeded in reducing overall carbon dioxide emissions by half. Despite the success, this paper views that the carbon emissions are still high for a single event and hence there is room for reduction of carbon emissions to lower levels as possible. we can conclude that the Euro Cup 2020 indeed succeeded in reducing overall carbon dioxide emissions by half. Despite the success, this paper views that the carbon emissions are still high for a single event and hence there is room for reduction of carbon emissions to lower levels as possible. we can conclude that the Euro Cup 2020 indeed succeeded in reducing overall carbon dioxide emissions by half.

An Analytical Solution for the Two-Layered Composite Beam-Column with Interlayer Slip and Constant Axial Load
14-31Megtekintések száma:67The authors present an analytical solution for the two-layered composite beams with imperfect shear connections. The considered beam is simply supported at both ends. The beam is subjected to transverse and axial loads. The kinematic assumptions of the Euler-Bernoulli beam theory are used. The connection of the beam components is perfect in normal direction, but the axial displacement field may have jump. The shear axial force derived from the imperfect connection is proportional to the relative slip occurring between the layers. The determination of the analytical solution is based on the Fourier method. Two examples illustrate the application of the presented analytical method.
