Connections between settlement structure, land use and the process of gypsy segregation in Hajdúböszörmény
Published December 22, 2010
41-50

The main aim of this study is to explore the connections between the unique settlement structure circumstances of Hajdúböszörmény and the social problams related to the gypsy minority. After the change of regime, the gypsy population increased especially quickly in some parts of the city, which is in connection with the settlement network p...osition and the internal division of the settlement. The significant segregation of the gypsy
minority appeared as a new phenomenon in the city, whose reason was the increasing migration of gypsies from Northeastern Hungary and the relatively low price of the abandoned real estates located in the outskirts and external settlement parts of the city. Even the gypsy population living in the city for a long time separates itself from the immigrant groups that live in run down houses and practicle have no connection with the job market of the city. It is the typical rural segregation process known only in small village regions (e.g. Southern Baranya, Cserehát) that now goes
on in the outskirts of Hajdúböszörmény.

Connections between the roma segregation processes and home circumstances in the outskirts of Hajdúböszörmény
Published May 16, 2012
57-61

In order to analyze the social status of local gipsies – both inside the community and among themselves – we conducted an empirical research of 300 participants, in which we took the distinctive spatioand sociostructural features of Hajdúböszörmény into consideration. Furthermore, a second research was also carried out in which we quest...ioned 25 prominent persons. Participants were selected in a way that the study may give a realistic picture of each of the segregated areas of the town (focusing on social, educational and realty issues), thus besides questioning professionals dealing with the concern of gipsies on a daily basis, we decided to involve representatives of the local government as well. The reports concerning the realty status of the segregated areas were supplemented with further material provided by the local government.

The settlement structure-related characteristics and social processes of Hajdúböszörmény after the millennium
Published July 18, 2012
49-56

The spatial structural position of Hajdúböszörmény (ease of access) and its economic and social endowments which are more favourable than those of its surroundings make the town more desirable as a target of migration. These endowments are rather advantageous on their own, but the specific settlement structure of the town results in the fac...t that concentrated, unmanageable and majorly segregated social crisis points have developed in some easily circumscribable parts of the settlement which could lead to a social explosion.

The effect of the plant density for the yield of the maize hybrids
Published May 23, 2006
50-61

In order to enchance the yield stability of maize, the effect of plant density on yields was studied on a typical meadow soil in Hajdúböszörmény between 2002-2004. In the plant density experiment, we used the method of Béla Győrffy. The plant densities applied therefore 20 to 100 thousand plants/ha by ten thousand scale. The application o...f fertilizer rates for the maize hibrids in every year were N: 110 P: 90 K: 120 kg/ha. We used a manual soiling-gun in the experiment. In every year we used plant protection techniques against monocotyledonous and dicotyledonous weeds. The harvest was done by hand. The facts were read by variancie analysis and linear regression analysis. The moisture and the temperatures were extreme in 2002, 2003, 2004. We have to mention defficiery of moisture in 2003 which is shown that the hot days number increased. After evaluating our findings we can conclude that most hybrids showed a significant correlation between increased plant density and the volume of yields. On the basis of the experiments we divided the hybrids into four groups: the first group included the hybrids suitable for increased plant density with a wide range of optimal density values; the second group included hybrids, which did not require high plant density, were capable of good individual performance and tended to grow several ears; the third group included flexible corn types, which grew longer ears in favourable years, thus yielded more; and the fourth group included the hybrids, which were sensitive to increased plant density and which showed a narrow range of optimal density values. Finally, plant density determines the yield; we have to consider optimal plant density intervals as well as optimal plant density, and we also have to place a high emphasis on the use of hybrid-specific technologies.

The effect of long-term fertilization on the 0.01 M CaCl2 extractable nutrient content of a meadow soil
Published December 16, 2012
73-79

During my research, I studied the 0.01 M CaCl2 extractable NO3--N, NH4+-N, Norg, P and K contents of the soil samples originated from a long term fertilisation trial in the experimental site Hajdúböszörmény. Relationships among the soil nutrient contents, the agronomic nutrient balances... of the 2009 year, and fertilization were studied. 
From the results of the study it was concluded as follows:
– Fertilization significantly increased the CaCl2 extractable NO3--N, NH4+-N, and K contents of soil.
– Norg fraction increased as a function of the increasing yield. Hence, it can be assumed that the greater the produced yield, the more the stubble and root residues remain on the arable land. These organic residues can result significant increase in the Norg content of soils.
– The CaCl2 extractable P and K contents were compared with the calculated P and K limit values. According to these, the experimental soil has a good phosphorus and lower potassium supply capacity. These results are in accordance with the results of the conventional Hungarian fertilization recommendation system.
– It can be stated that the 0.01 M CaCl2 is able to determine not just inorganic N forms but Norg fraction as well that characterize the easily mineralizable nitrogen reserves. The results proved that AL-P and -K (ammonium lactate acetic acid, traditional Hungarian extractant) are in good agreement with the P and K reserves, but it is important from the aspect of environmental protection and plant nutrition to measure the easily soluble and exchangeable K-, and P-contents of soil. 0.01 M CaCl2 method is recommended for this.

The effect of sowing time on the yield and the variance of the seed moisture content a harvest of maize (Zea mays L.) hybrids
Published May 23, 2006
39-49

Sowing time is an important crop technology element of maize. We studied the effect of this factor on the growth and production of maize in an experiment carried out near Hajdúböszörmény, in 2003 and 2004, and near Debrecen, in 2005.
The soils of the experiments were humic gley soil and chernozem. Weather in both years differed greatly. ...2003 was drought. Neither the distribution, nor the quantity of the precipitation were suitable in the growing season for maize. This fact basically determined the results.
In 2004 and in 2005, there were favorable and rainy seasons. The distribution and quantity of precipitation were suitable between April and September. The average temperature was also suitable for maize.
In 2003, we tested seven hybrids at four sowing times. Hybrids with a shorter vegetation period gave the highest yield at the later sowing time, while the hybrids with a longer vegetation period gave them at the earlier sowing time. The yield of PR34B97, PR36N70, PR36M53 hybrids were the best at every sowing times. The moisture loss of hybrids in the late maturity group was faster in the maturity season, but the seed moisture content was higher than the hybrids with early sowing time. The seed moisture content was very low due to the droughty year. In two hybrid cases, this value was higher than 20% only at the fourth sowing time.
In 2004, we examined the yield and seed moisture contents of nine hybrids. In the favorable crop year, the yield of every hybrid was the highest at the second and third sowing times. Yields of PR34H31 and PR38B85 hybrids were significant. The seed moisture content at harvest was higher than the previous year, due to the rainy season. In the case of hybrids sown later, this value was higher by 30%. However, we noticed that this value was lower at the earlier sowing time, than at the later.
In 2005, we applied three sowing times. Unfortunately, the results of the third sowing time could not be analyzed, due to the low plant density. The yield of the six hybrids varied from 12 to 14 t/ha at the first sowing time. At the second sowing time, the yields fluctuated and each hybrid had the lowest yield, except the PR37D25 hybrid. At the latest sowing time, the yield of the PR34B97 hybrid was the lowest. However, this low yield was due to damage from the Western corn rootworm (Diabrotica virgifera) imago. The moisture content at harvest of the hybrids varied from 16 to 24% at the first sowing time. Yields at the second sowing time were higher. The low yield of the PR34B97 hybrid coupled with a higher seed moisture content. In addition, the maximum value of the LAI was more favourable at the first sowing time, and ranged between 5-5.5 m2/m2.
The crop year had a more dynamic effect on maize than the sowing time. First of all, the quantity and distribution of precipitation played an important role in respect to yield safety.

Foliar treatments of Sugar beet
Published November 15, 2007
55-59

The yield and quality of the sugar beet are mainly determined by the plant production system, thus we studied the effect of mineral fertilization. Our field trials were carried out in 2005 and 2006 in Hajdúböszörmény, at two sites. We studied the effect of sulphur (Cosavet DF), copper (Kelcare Cu) and two foliar nutrients with high active a...gents. Treatments were replicated four times.
We took root and leaf samples at 4 week intervals, starting in August. The quality of root (sucrose, potassium, sodium and alfaamino N content) was determined from filtrated beet broth, by an automatic beet laboratory system, called VENEMA. Leaf samples were measured with ICP-OES.
We found that the crop and the sugar yield were significantly influenced by the foliar treatments.

Effect of Planting Time of Maize on Factors Influencing Yields in 2001-2002
Published May 11, 2003
112-116

In this paper we analysed the results of maize planting time experiments by the Department of Crop Sciences and Applied Ecology of the University of Debrecen, Centre of Agricultural Sciences in 2001. We made the experiments at the experimental garden of DE ATC in Hajdúböszörmény.
We examined in 2001, 2002 ten hybrids with three planting ...times. The results were analysed by analysis of variance with two factors. In 2001 the yields were high, between 7.2-11.6 t/ha. The seed moisture contant of hybrids was 6-8% less after early planting than after late planting. The vegetation period of the hybrids became longer after early planting, which helped the drying-down of the hybrid and determined the seed moisture content at harvest to a great extent.
In 2002 the yields were high, between 4.02-10.47 t/ha. The seed moisture contant of hybrids was 5-14% less after early planting than after late planting.
On the basis of the above, variety specific technologies should be applied where the planting time is adapted to the hybrids. In accordance with the other cultivation factors.

...5); font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">The most important instrument of social advancement and economic development is the education system. The educational qualification of the population of Hajdú-Bihar county is continuously improving, however the census data of the year 2001 show that the educational qualification of the population of the county did not reach the national average. The educational qualification of the county’s population is higher at the county seat and in other cities and lower in small municipalities. The county’s ratio is strongly influenced by the data of the county seat Debrecen and that of Hajdúszoboszló sub region.

The unfavorable educational level of the region is related to the migration tendencies and the brain-draining trends of the past decades, as a consequence of which the population of the less developed eastern regions has moved either to the capital, or to the county seats, or larger cities of the region. The young are increasingly affected by the process.

The number of kindergartens in the county corresponds to the national average, therefore taking into consideration the regional demographic characteristics the aim should be the equalization of regional disproportions. The number of students per 1000 resident within the Northern Great Plain Region and in the county significantly exceeds the national average. The secondary school network of the county consists of 38 secondary grammar- and 51 secondary vocational schools.

The secondary schools of Debrecen have considerable impact on the county’s secondary education. The vocational training network of Hajdú-Bihar county is a large, in its conditions highly differentiated institutional network in which all types of secondary vocational institutions are present with secondary technical-, vocational-, accredited higher vocational-, specialized or preparatory vocational-, and special skill enhancement programmes. The majority of the secondary institutions have regional, rarely national enrollment.

Students who have the intention to continue their studies in higher education within the county can study in Debrecen or Hajdúböszörmény.

The integrated University of Debrecen has the highest student number within the country and it offers the widest range of academic programmes in Hungarian higher education. The University of Debrecen with the wide range of graduate and postgraduate educational programmes, unified academic qualification system, English language programmes is a European standard scientific centre of the Trans-Tisza Region. The county’s higher education takes exceeding share beyond its weight in the education of Natural Sciences (Biology, Physics, Chemistry, Earth Sciences, Mathematics), Health- and Social Sciences, Agricultural- and Environmental Sciences and Information Technology, which positively influences its educational structure. The county’s share in the education of Humanities (Hungarian Language, Foreign Languages, History, Archeology, Philosophy) is also significant.

6.3% of the country’s scientific researchers work in the county. In 2010 7.0% of the country’s R+D expenditure was spent here. 3/4 of the region’s research capacity is in Hajdú-Bihar county employed either by the University of Debrecen or by the research teams of the Hungarian Academy of Sciences.

The Effect of Sowing Time and Plant Density on the Yield of MaizeHybrids
Published December 6, 2005
95-104

The crop technology of maize has two important elements, sowing time and plant density. In 2003 and 2004 we studied the effect of these two factors on the growth and production of maize in an experiment carried out near Hajdúböszörmény.
The soil of the experimental plots was meadow soil.
Weather in both years was differed greatly. 200...3 was drought. Neither the distribution nor the quantity of the precipitation were suitable in the growing season for maize. This fact basically determined the results.
In 2004, we could talk about a favorable and rainy season. The distribution and quantity of precipitation was suitable between April and September. The average temperature was also suitable for maize.
Results of the sowing time experiment:
In 2003, we tested seven hybrids at four sowing times. Hybrids in the early maturity group gave the highest yield at the later sowing time, while the hybrids of the long maturity group gave it at the earlier planting time. The yield of PR34B97, PR36N70, PR36M53 hybrids was the best at every planting time. The moisture loss of hybrids in the late maturity group was faster in the maturity season, but the seed moisture content was higher than the hybrids with early sowing time. The seed moisture content was very low due to the droughty year. In two hybrid cases, this value was higher than 20% only at the fourth sowing time.
In 2004, we examined the yield and seed moisture content of nine hybrids. In the favorable crop year, the yield of every hybrid was the highest at the second and third sowing time. Yields of PR34H31 and PR38B85 hybrids were significant. The seed moisture content at harvest was higher than the previous year due to the rainy season. In the case of hybrids sown later, this value was higher by 30%. However, we noticed that this value was lower at the earlier sowing time than at the later.
The crop year had a more dynamic effect on maize than the sowing time. First of all, the quantity and distribution of precipitation played an important role in respect to yield safety.
Results of the plant density experiment:
We tested the reaction of hybrids at four plant densities (45,000, 60,000, 75,000 and 90,000 stock/ha) every two years. In 2003, the tested seven hybrids reached the highest yield at the 90,000 stock/ha in the face of a droughty year. The effect of forecrop and favorable nutrients caused these results. In the rainy 2004 year, the yield grew linear with the growing plant density. The yield of the best hybrids were 14-15 t/ha at the 90,000 stock/ha.
Such a high plant density (90,000 stock/ha) couldn’t adaptable in farm conditions in rainy season. It is practical to determine the interval of plant density besides the optimum plant density of hybrids which gave correct yield. The farmers have to use the low value of this interval due to the frequent of the droughty years.

Exploration of relations among the members of the supply chain on the basis of relationship indicators
Published April 8, 2014
177-190

Today the various business units on the market are not competing individually against each other, but doing this as members of a supply chain, which are delivering the products or services to the customers with coordination. The participants are cooperating in the process of purchasing, production and sale. Their common objective is to deliver ...for the consumer demand. The supply chain approach of the enterprises is a business philosophy, which requires trust, commitment, coordination, shared objectives, support from the management, and the understanding and acceptance of the mutual dependence (Német, 2009). The main objective of our study is to analyse the relationships among the players of the supply chain through several relationship indicators, such as trust, economical satisfaction, social satisfaction, compelling power, non-compelling power, dependence, reputation and conflict. The relationship among the players of the supply chain has been analysed from two aspects, through the position and through the role of the players of the supply chain. This study aims to present the results of the analysis highlighting the critical points.

Examination of the connection between the theoretical framework and practice of workplace integration in the case of American concerns
Published April 8, 2014
119-123

The first part of this essay presents the definition of workplace socialization, workplace orientation, workplace integration and onboarding on the basis of English literature. It also illustrates the human resources and management tasks and responsibilities in the process of onboarding.

Considering the literature I set up questions for... a half-structured interview completed with American HR managers by the help of skype program. The results pointed out that the professionals refer only a few elements of definitions, and the onboarding term is used for other HR practices (recruiting, selection), too. Furthermore on the basis of the results the onboarding process in well-organized and managed, and also the related human resources and management tasks and responsibilities are correctly appointed within the examined companies.

Additionally this examination verified our previous results which showed that there is a strong documentation and controlling in the process of onboarding within American enterprises.
