Inbound and Outbound Tourism in China: A Perspective Article
91-107Megtekintések száma:134The 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. To reach its full potential, China needs to adapt to the shifting global environment and take into account the specifications and preferences of both inbound and outgoing tourists.

Improving Safety & Ride Comfort through Dual Suspension System in Road Vehicles
30-36Megtekintések száma:151The 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:167The 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.

Role of Lean and Agile Supply Chain Models for Pellet Fuel Technologies
119-130Megtekintések száma:135Business organisations constantly strive to improve their processes, both internal and external. Within the supply chain of a product, different strategies can be applied. This paper aims to answer the basic questions like what is the core of lean and agile SCM strategies, what are the differences of the two models, and how can they be combined. This paper examines further, which of these SCM models and what elements of them can be applied for wood pellet supply chains, also examining the possibility of their combination. The result of these examinations is, that even though fuel pellets can be considered as simple commodity and not a very innovative product, diversity in input characteristics, optimization of fuel pellet technology process variables and changes in output market qualities and quantities need sometimes agile, flexible answer from pellet fuel SCM. The basically lean character of pellet fuel technologies and SCM can further enhanced by implementing agile SCM model elements, as is the increased integration of suppliers into the supply chain.

Generative Design of Articulated Rod of Radial Engine
36-47Megtekintések száma:413The 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. Also, finite element analysis (FEA) was investigated on the part as to ensure the reliability of the rod before and after optimization.

Viselhető technológia használat a Debreceni Egyetem hallgatói körében
33-47Megtekintések száma:109Világszerte 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.

Effect of the Flow Curve Determination on the Thinning of Drawn Parts
16-25Megtekintések száma:57This study presents the results of finite element simulations based on different variations of the flow curve of DC04 automotive thin sheet. The aim of our research is to investigate how different flow curve equations affect the variation of sheet thickness in cup drawing tests. In order to exclude other influencing factors in the experiment, both the sheet material and the geometric properties of the specimen, as well as the external state factors were considered to be the same in all cases. The finite element simulations were performed using Simufact 2021.1 software. Our results shows that there are no significant differences in wall thicknesses until we reach the zone of double necking, where essential differences are observed.

An Analytical Solution for the Two-Layered Composite Beam-Column with Interlayer Slip and Constant Axial Load
14-31Megtekintések száma:46The 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.

Testing the Sametest-effect in a BSc-level Business Communication Course Examination
10-15Megtekintések száma:56Using secondary data, we empirically examine two biasing effects that may arise in the written evaluation of large groups of students. Suppose the students take the examination in consecutive groups, and we wish to avoid the distortion caused by tests of different difficulty. In that case, we can decide to use the same examination questions. However, the danger of the "same test effect" arises, according to which the group writing later can perform better if it receives information from the examinees in the previous round. Using the same examination tests cannot be recommended if that effect is significant. Another related potential phenomenon is the "revealed sameness effect". Accordingly, if the examinees are aware of the repetition of the questions, it significantly increases the scores of the following group. We tested these phenomena using the data of a three-round written examination. A previously published analysis of a larger sample found that the "same test effect" can be expected if the students decide in which round they take the examination. Since it was possible to freely register for the examination rounds for the assessment analyzed in this study, we assume that the "same test effect" will be significant. Based on the literature, we also expected that the "revealed sameness effect" would occur in the third round. The performed linear regression analysis (N=77) only found some weak evidence for the 'revealed sameness effect' but not for the 'same test effect'.

Was UEFA’S Goal of an Environmentally Friendly Euro 2020/21 a Success?
152-164Megtekintések száma:506The 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.

The Effect of the Excess Titanium Content on the Microstructure of Al – Si Foundry Alloys
12-20Megtekintések száma:104Grain refining is an important technological step for the nucleus growth of the melt, in order to increase the number of nuclei, to improve mechanical properties (tensile strength, yield strength, hardness, elongation), feeding conditions and to decrease the tendency of hot tearing and the degree of sintering. [1][2] The aim of the experiments was the determination of the grain refining effects of titanium (Ti) addition in the form of AlTi5B1 master alloy to the examined alloys (AlSi7MgCu0.5 – AC 42 000, AlSi9Cu3Fe0.5 – 46 500; AlSi9Cu1 – AC 46 400). The results prove that the addition of small amount of master alloy has a favourable effect on the foundry practice.

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:131As 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.
