Opportunities to the urban air quality of characterization by the cost-effective electrochemical sensors
1-16Views:82The quality of urban is more and more affected by the accelerating urbanization. The efficiency of improving air quality can be increased by providing local information on each pollutant source. The aim of our activity is providing real-time high-spatial reasultion data about air quality of the Hungarian capital city, Budapest. In this paper, results of testing and calibration of different low-cost electrochemical sensors and localization of them are represented. The first selected sensor is suitable for detecting carbon dioxide (CO2), alcohols, benzene (C6H6), nitrogen oxides (NOx) and ammonia (NH3). The RingAir initiative also aims to involve the urban population in active environmental monitoring activities, therefore in the future we are planning to implement a more detailed and continuously updated monitoring system with the participation of a Budapest bicycle courier service and some of the city's population.

Polylactic Acid as a Potential Alternatives of Traditional Plastic Packagings in Food Industry
123-129Views:317Huge quantity of synthetic polymers is used as packaging materials in different fields of food industries. A significant part of these polymers applied as a primary, direct food contact construction. The scoped application area is the sweet industry. In this field Polystyrol (PS), Polypropylene (PP) and Polyethylene terephthalate (PET) have used but during the last fifteen years the usage of PET has been grown. In one hand the price of this material is efficient, form other hand the PET is the one of the most safe (for food industrial applications) petrol chemical plastic that can be used as primary or secondary food contact packaging material. To maximize the customer safety and minimize the environmental impact of traditional PET, a new bio-sourced and bio-degradable alternative polymer aimed to be used in this special food industrial segment. One of the potential alternatives is the Polylactic acid (PLA) that would be a possible substitute as it is compostable and produced from renewable sources and has good physical and mechanical properties [1].

Gamification in the field of human resource, a creative solution for recruitment
373-382Views:625With the introduction of latest tools and the expansion of technological solutions, the usage of smartphones ,with instant internet connection of course, has become an essential part of the net generation, also known as generation Z. At the same time, the role of IoT devices has also become part of our daily lives, completing and sometimes making it easier. This is due to the fact that the tools become more and more cheaper as time passes and parents and young people no longer consider these a technical innovations, but as a necessity. These generations; Y, Z and Alpha appear simultaneously on today's job market, which poses a serious challenge to future HR leaders and recruiters. Because of the generational gap between them, both motivational and demanding, novel solutions are becoming increasingly appreciated in this area as well. The purpose of this study is to demonstrate the potential of gamification and to highlight the its major areas, as well as to draw the attention to "good practices" in creative recruiting through better known examples. In addition, I also tried to point out the effect on the relationship between motivation and flow-experience. The gamification method is becoming more and more popular in our country, as it plays an increasingly important role in business and education as well. In recent years, with the use of serious games, there have been several examples of HR recruitment and selection, which clearly strives to reach out to younger generations.

Optimizing the combustion processes of a small scale solid fuel-fired boiler
358-369Views:120Over the last decade, the public has been paying increasing attention to reducing greenhouse gas and acid rain emissions and reducing particulate matter, which is extremely harmful to health and the environment. To improve air quality, the European Commission has achieved a range of measures to reduce air pollutant emissions in the transport, heat and electricity, industrial and agricultural sectors. In Hungary, the amount of gas and solid air pollutants from solid fuel combustion used by the public during the heating season represents a significant percentage of the total amount present in the atmosphere. In 2016, taking into the total emission, the 29% of CO2 emissions; 85% of CO emissions; 75% of the particulate matter emissions and 21% of the NOx emissions were derived from households. It follows that the improvement of air quality can also be achieved by controlling the emissions of solid fuel combustion plants. During our research we aimed to optimize the operation of a newly purchased TOTYA S18 boiler and a pilot pellet boiler. Operating the boilers in the correct mode minimizes air pollutant emissions, and the greater part of the heat generated is actually turns to heating the home, as with poor settings, a lot of heat leaves through the chimney. The data obtained during the tests can also be used to determine whether the boilers comply with the emission values set out in Commission Regulation (EU) 2015/1185.

The Empirical Examination of Different Customer Types
92-100Views:117The proper knowledge of customer types is essential for a well functioning company – regardless of its size. In current research we wanted to identify and characterize the particular customer groups with involving 302 persons. During the examination we measured the attitudes of these participants with the help of a statement range based on Kotler’s classical customer types. For the identification we made factor- and cluster analysis, and we could separate five different factors. They received the names of Angry, Definite, Discursive Passive, Experience Shopping and Indefinite - based on some related statements. After the cluster analysis – along these factors - we could separate four different groups: Young Impulse Shoppers, Outspoken Definites, Negatives and Born Customers. Each and every group requires different communication, sales attitude and service morals.

Production of Liquid Hydrocarbons from Plastic Wastes
345-350Views:114Thermal pyrolysis of HDPE, LDPE, PP and PS plastic wastes were performed in a batch reactor and the yields of pyrolysis oils and liquid transportation fuels prepared by atmospheric distillation were determined. The gasoline fractions were tested in a traditional spark-ignition engine without any modifications or fuel blending. Fuel consumption and exhaust gas emission (NOx, CO) were measured and compared to a commercial fuel (RON = 95). PS generated 70.5% gasoline range hydrocarbons from the solid waste, followed by PP with 42.1%, LDPE with 40.8% and HDPE with 37.3%. The fuel consumption was reduced by 9.1-9.4% in the case of PS compared to reference measurement. Reduction in fuel consumption was noticeable at HDPE, LDPE and PP as well. PS gasoline decreased by 91-96%, while HDPE, LDPE and PP more likely increased the CO emission of the engine compared to commercial gasoline. The results show that pyrolysis of plastic wastes is a promising method to generate value added liquid transportation fuels and reduce the footprint of waste accumulation in landfills.

About Gamification & What Do We Use for Nowadays
171-180Views:747By the widespread increase of new technologies, Internet has become an essential element for generation Z, however, this is not particularly surprising given the fact that over recent years different IoT solutions have become widely available, well-known and increasingly cheaper. Thus the grown up of Net Generation brings innovative solutions to the fore by which motivation is not forced to students anymore but there will be a real internal demand from their side in accordance with the age of Motivation 3.0. If this will be the case, the social issue of Homo Ludens will be also appeared in parallel to gamification [1]. Gamification nowadays is a method that become more widely used depending on field of use, thus it may meet needs of businesses and also educational institutions. The term of gamification is understood to mean those technics and methods when game elements are used in non-gaming environments [2]. Since we do not concentrate on learning during games, students will find learning a pleasure rather than an imposition and it means many could improve their skills or receive information without realizing they are actually studying. Moreover, despite the traditional learning method, the knowledge acquired this way can be used for a long time during seminars and later on labour market. Gamification plays an increasingly important role in business and also in education [3]. Students may learn more effectively and with a lower effort using gamification. As a result, this innovative approach of learning has been becoming more and more popular internationally, furthermore, motivation shortage problems also could be solved by this method [4].

Development and Characterization of Sisal Fiber Reinforced Polypropylene Composite Materials
348-358Views:332In most of the developing countries, plastic polypropylene is not fully recycled and converted in-to use after it is once used. Sisal fiber is also widely available in different developing countries like Ethiopia. Adding this two materials and developing automotive interior part was taken as a primary motive for it reduces cost and is environmentally friendly. Thus, the main purpose of this research is to develop composite material from natural fibre (sisal fiber) reinforced with recycled plastic waste (polypropylene) for interior automobile accessories specifically for internal door trim panel application. This research examines effect of fiber length, fiber loading and chemical treatment of fiber on the physical and chemical properties of the sisal fiber reinforced polypropylene (SFRPP) composite material. The waste polypropylene and the treated and untreated sisal fiber with variable length and weight ratio (fiber/matrix ratio) were mixed. Flammability of sisal fiber reinforced Polypropylene (SFRPP) composites material was examined by a horizontal burning test according to ASTM D635 and chemical resistance of the sisal fibre reinforced PP composites was studied using ASTM D543 testing method. The result on the flammability test shows that treated fiber has lower burning rate than untreated fiber and decreases with increase in fiber length and fiber loading. The resistance of the composites to water has increased as the fiber length increases and decreased as the fiber loading increase. Generally, SFRPP composite is found to have better resistance to water than NaOH and H2SO4 and treating the fiber has brought considerable improvement on chemical resistance of the composite. Fiber loading and fiber length has positive and negative effect on the flammability of the SFRPP composite respectively.
