Value Creation along a Production-Service Value Chain
91-99Views:332Today’s products and services are so complicated and intertwined that their individual value creation is hard to determine. It is especially true when the products and services are necessary complements of each other and when they are affecting customer satisfaction for a long time. In the case of durable products needing professional installment service, the study of value creation poses many difficulties. Our research shows and emphasizes the process characteristic of value creation, and how the different steps (production, service, long-term use) should be looked at, and what further analyses can be done.

Digitalization Process by Agricultural Companies, or the Results of a Questionnaire Survey
625-636Views:397The term “information society” first appeared in Japanese social science in the early 1960s (Z. Karvalics, 2007). The interpretation of the concept has undergone significant changes over the past decades, showing that dynamically developing societies, which are undergoing constant changes due to the rapid development of information, information management and the dynamism of the digital world. The close relationship and connection between information and information technology has become a fundamental factor in the societies of today, the organizations life, which generates inevitable, sometimes serious debates and profound changes. Economic operators must necessarily be resilient to technological change. We should think of the time of the Industrial Revolution, when modern weaving machines flooded the factories. Otherwise, a resilient organization will not survive in an evolving and ever-changing dynamic economic environment. Of course, this is true of agriculture as well, just as it is for other sectors of the national economy. On the one hand, my assumption on the basis of which my questionnaire was compiled was that enterprise management systems are increasingly used by enterprises in agriculture due to the diversification of activities. At the same time, I assumed that the size of a business could influence the use of information technology (hereinafter IT), so I hoped that my research would provide reliable data on this as well.

Efficiency Analysis of Production Management System
401-415Views:329Due to the continuously evolving technology, even more escalating market competition has emerged between the companies. This competition is not only about the logistics related processes, it also appears to be significant for the production since the manufacturing companies form the center of global sale streams and without them the items found in logistical processes cannot be created. The role of production’s optimization and efficiency in the supply chain continuously grows since this is the part where a company’s most cost is produced. Our research objective was the examination of a company that applies various manufacturing, assembly technologies, and the used tools and softwares for this purpose were the SAP Business One ERP system and it’s add-on, called PPS One, the latter originated in Switzerland. We used these softwares to provide solutions to companies, especially to those that are dealing with manufacturing and production, for the optimization of their workflows, operations, supervising and controlling of their material. We also monitored from production technology’s elements the capacity planning, production orders, schedules, production tracking and cost accounting. We have made proposals during the analysis that might improve the company's strategy, competitiveness and increase it’s efficiency in business, and at the same time they can facilitate the company's pricing and inventory management activities.

Policy Gaps and Health Risks: Addressing Women’s Indoor Air Pollution Exposure in Pakistan
109-121Views:45Indoor air pollution currently poses a significant challenge, adversely impacting both the physical and mental health of women. The substantial use of fossil fuels for domestic chores endangers women's health and exposes them to considerable risks. In this regard, this study elucidates the factors driving the use of fossil fuels in domestic kitchens in Pakistan. The association between primary indicators such as women's health, duration of women’s current pregnancy, and pregnancy status with household air pollution is analyzed. We use Ordinary Least Squares (OLS) regression in Stata, and the results indicate that the type of cooking fuel significantly affects women's health. Furthermore, indoor cooking also negatively influences the duration of pregnancy. Based on these results, the paper provides practical policy recommendations for governments and policymakers to mitigate health risks. This study is instrumental in analyzing the current state of household air pollution, offering a robust model for countries heavily reliant on fossil fuels, and examining the consequent health impacts on women.

HAZ Characterization of Automotive DP Steels by Physical Simulation
478-487Views:367DP steels were extensively used in the vehicles industry due to its extraordinary combined properties of strength, ductility, formability and weldability which contributed great significance in reducing strength to weight ratio and CO2 emission. High strength steel i.e. DP steels (3 different grades) were experimentally investigated and thermophysically simulated using Gleeble 3500 simulator to determine softening and hardening in heat affected zone. Samples were heated to different peak temperatures (1350 °C, 950 °C, 775 °C and 650 °C), two cooling time (t8.5/5 = 5 s and 30 s) and Rykalin 2D model were selected. The hardness and microstructure of the specimens were tested and analysed. For longer cooling time (t8.5/5= 30 s), we observed that softening occurs in all grade of investigated DP steels to all sub-regions. But for shorter cooling time i.e. t8.5/5= 5 s the softening is higher in intercritical HAZ compared to other sub-regions for all the types of DP steel with short cooling time (t8.5/5 = 5 s). However, the hardening zone in the CGHAZ occurs when Tmax is 1350 ºC for DP600, DP800 & DP1000 steels but it is more prominent in DP800 as compared to others two steel grade.

Investigation of the Resistance Force Acting on a Sailing Craft in the Case of a Change of Draft Caused by a Change of Powertrain Using Numerical CFD Simulations
30-35Views:382Nowdays In the case of recreational craft, interfering with motor drive solutions is a common workflow due to increasingly strict rules for environmental reasons. When switching from an internal combustion engine to an electric engine, the change in draft varies from boat to boat, but it can be said in all cases that as the mass changes, so does the draft. Because of this, the magnitude of the resistance force acting on the ship also varies. In this paper, we examine, through a specific example, the benefits of a change in dive caused by weight gain at different travel speeds.

Comparative Analysis of the Notes on the Accounts Of Information-Technology Servicing Companies in Hungary
186-194Views:438In the globalized and accelerated world of our time, challenges can only be met by companies that possess the necessary information and are able to convert it rapidly into organizational knowledge. Annual accounting statements are an important source of information within business relations among companies. The necessary information can only be obtained from the two fundamental parts of the annual statements (balance sheet and profit and loss account) if the notes on the account contains the information that contribute to the more comprehensive interpretation of the other parts of the annual statement. Decision-making based on inadequate knowledge further increases economic risks that are already high. In our research, we examine whether the notes on the accounts of companies include the information, which could help obtain necessary financial knowledge concerning the partner companies. For the analyses, we used the notes on the accounts of companies, which have information-technology services (Hungarian NACE No. 62) as their main line of business. By means of text mining, we analyse the extent to which the notes on the accounts are in conformity with the Accounting Act.

The Implementation of the Japanese and the German Culture into the Operation Hungarian Firm
1-9Views:380How can the Japanese culture be implemented into the operation of a firm - partly a German property working in Hungary. In my presented arcticle I have studied various organisational culture models, and compared them to the culture of our enterprise, seeking for similarities and contraries. I have studied the environmental factors and resources which have an effect on our production. During the investigation I have also considered how can we harmonize cultures of different nations and how it affects the production on the whole. I have also investigated the installation of robots, and searched for the solution how we can make our production much more economical. Due to the persistent decrease of population, and leck of professionals, the use of robots is neccessary to fulfill the customer requirements in time, with the sufficient quantity and required quality of goods. According to the Japanese Toyota-method,theautomatization of a technology can only be successful, if it is tested at least ten times, but –beacuse of the leck of time- we do not have the possibility of it. As the manufacturing parameters and observations have not developed the proper way, the scrap rate is higher than it is at firms, where is more available time for the building up of the technology.

Reducing the use of chemical for biological wastewater treatment by technological modification
107-113Views:233In the Wastewater Treatment Plant of Debrecen Waterworks, the experts working there fight daily with various problems typical of the Hungarian plant. Suitable denitrification requires the administration of an organic substance in many cases containing biodegradable organic matter. Between January 1 and December 31, 2017, 183.1 t of organic matter was needed. It was important to develop a solution for the site's specialists to ensure efficient biological wastewater treatment without the need for additional carbon input in the technology. We have also supported calculations to ensure stable denitrification irrespective of the fluctuating C/N ratio of incoming sewage. Thus, it would be unnecessary to add up to 200 tonnes of organic matter per year to the technology without which biological wastewater could be achieved.

Examining Drone Logistics Solutions in Retail
48-61Views:326The possibilities of using drones in transportation will be determined by the capabilities of drone technology, legislation, various advocacy and trade unions, and the degree of general acceptance. Technology and infrastructure are given, customer habits and needs are favourable, and emissions generated by packets moving between two points are growing steadily. Despite these favourable conditions, the effects of drone use should be thoroughly reviewed. The environmental impacts of the project were analyzed by PEST analysis and the main influencing factors were studied using the Porter model. Concluding our results based on questionnaire surveys and feasibility examinations of fast food delivery, it can be said that a system based on drones can efficiently be operated and cost-effective using round trips, however, the legal issues and uncertainties that arise in the delivery of drone hippers remain a very significant hindering factor for a long time.

Temporal Changes of Pyrite Oxidation Rate in Bolivian Sulphidic Mining Wastes
194-202Views:207Since the 70's, when huge sulphidic open pits were developed, the acidic rock drainage (ARD) become the leader problem of the sulphidic mining industry. Although the recycling is an essential technology, it cannot cover the demand alone, thus mining activity needs to continue. Acidity in mine drainage commonly requires most of the attention, but the main problem is the caused elevated level of metal mobility and leaching, which are generated by the increased rates of sulphide weathering under acidic conditions. The Itos mine is a polymetallic vein deposit in Bolivia, had been mined for silver and tin until 1990, leaving behind much and huge tailings and mine waste heaps, where quite often the pyrite content exceeds 10 %. Serious ARD effects take place in the mine waste heaps. These processes can be well characterized with the pH 1 or 2 of the seepage water, which forms serious alteration in the waste itself and the neighbouring rocks. In three consecutive years, the pyrite oxidation rate was investigated on the same 7 samples by humidity cell test. 5-6 months pauses were left between the humidity cell test periods, which mimics the alternation of wet and dry periods, typical for the place. The results give much more information, than the oxidation rate in the individual test periods, showing the changes by time. This applied method gave good result to characterize the behaviour of the waste in long-term. The column test was complemented with mineralogical analyses, such as electron probe micro analysis. The mineralogical and column test analyses show, that the changes of the pyrite oxidation rate split the samples into three different groups, one where the oxidation rate decreases, second where it increases with time and the third where oxidation rate is maximal and stays stable for several years.

Sport Consumption, Fan Engagement, Sport Statistics – Post-specific Passing Characteristics in Football
Views:878Digitalization and the explosive development of technology have led to significant changes in football. Due to the increasing amount of data available through various sensors and other data collections, we can observe the rise of data-centric, analytical and statistically oriented thinking in football, which is also of interest to fans. Digitalisation is also closely linked to sports consumption, which is why we have seen significant changes in this area in recent years. The pandemic has further amplified the speed of digital transformation in the sports industry. One of the most important contents for sports organizations and their fans is the in-depth sports statistics and analysis that enhances the consumer experience. In our study, we examined the most common performance indicator in football, passing. Our goal was to examine the position-specific pass characteristics in detail, therefore we also examined different pass properties in our research. As a model for our analysis, I chose the premier league, which has the highest UEFA coefficient. The three rounds (rounds 30-32) of the championship season 2019/2020 have been recorded and analyzed in terms of passes. there was a significant difference between the average number of passes per game between defensive and offensive players (t=7,988, p<0.05). There is also a gradual decrease in the number of passes attempted per match and the accuracy of the pass in the examination of the middle positions when examining the positions in the depth of the pitch. For both pass accuracy and average pass count, the decreasing ranking corresponds to the position of positions on the pitch (order: 1, central defender 2, defensive midfielder 3, inside midfielder 4, attacking midfielder 5, striker). In the value indicator of the position for passes, offensive positions performed more effectively than defensive positions. The extreme positions also stand out among the attacking positions, where in the case of the position value per pass number, 23.3% of the total test was completed and 14% of the amount of the established position value indicators was provided by these posts. Overall, our study points to post-specific pass characteristics and, knowing this, we can state that the comparison of players' passing performance is relevant if the players are in the same or related positions.

The Effect of annealing temperature on corrosion resistance and microstructure of Zr-Sn-Nb-Fe alloy
420-424Views:257The Ti-2Al-2.5Zr titanium alloy plate in beta phase water quench at different times of the reentry after annealing is implemented while primary phase number and size distribution of samples are obtained. This research is carried out on corrosion behavior in 3.5% [mass fraction] NaCl solution. Experimental study showed that after the beta phase water quenching Ti-2Al-2.5Zr titanium alloyed after 500 oC annealing when partial recrystallization happened. There seems to be lots of tiny dispersion in the alloy that was annealed with its samples of six-party [HCP] structure of Ti, Zr, Al phase 2 with the dimension below 100 nm. Reaching 500 oC when the rate of annealing at a primary phase of the sample at 550 oC is low 90% of the primary phase is less than 100 nm. The changing of the rule of present decreasing also triggers little difference overall. Precipitation in the process of annealing Zr [Nb,Fe,Cr] 2is less that proves to be good for corrosion resistance.

What is worth knowing about the establishment from a work safety point of view
24-31Views:278Under establishment, we mean the process that results in the creation of a new unit (eg factory, plant, office, etc.), a workplace or an existing one what will be renewed, expanded or restructured, or installed; installed on a machine, plant, appliance, whether or not for productive or non-productive purposes. It is generally true that the design, construction, use and subsequent operation of workplaces, facilities, technology, materials, energy, personal protective equipment; production, distribution, import, transportation, movement, use and use of workplaces; in the absence of these, the requirements of the scientific-technical standard can be expected. An employer, operator, and service provider must adapt to market conditions. Accordingly, it should monitor the expectations of customers, business partners, market changes, trends to adapt to expectations, and therefore constantly develop their products, services, produce reliable quality, ensure that quality meets the market expectations providing personal and material conditions to ensure that employees can effectively and safely meet market expectations. The recognized business perception of the employer is to accomplish the above, the objectives to be achieved must be formulated, priority should be given to the potential risks (with particular regard to occupational safety risks) to be measured, measures to be taken to ensure effectiveness, short-, medium- and long-term planning, investment.

Exploring the Role of Emotions and Moods in Decision Making: Study on the Use of Structured Decision Approach and Intuition
140-149Views:583Emotions and moods can play a significant role in the decision making. The present paper contest this point by providing evidence on the two important approaches used in decision making that is structured decision approach and intuition. For this purpose data was gathered from 150 respondents in two different groups. Chi square test, independent sample t-test and logistic regression analysis were used to test the hypothesis. The results of the study reveal that individuals with positive and negative mood state vary significantly in their use of structured decision approach and intuition. The individuals with negative mood state are more likely to use all steps of structured decision approach as compared to the individuals in the positive mood state. The results of the study further reveal that the individual’s emotional state significantly predicted the use of structured approach and intuition in decision making.
