As a respected research institution, the Faculty offers also PhD study programmes in thirteen accredited fields of science for graduates from Slovak and foreign universities. The education at the Faculty of Science is provided by experienced teachers who carry out also research and closely co-operate with Slovak and foreign universities and research facilities. The research at the Faculty of Science at Šafárik University in Košice shows multidisciplinary character and due to this it covers a wide range of topics from molecular biology to computer and material sciences. The research in 2005 in the field of Biology and Ecology was directed towards the problems of biodiversity of plants and animals, biotechnology of medicinal plants, carcinogenesis, prevention and cancer therapy; in Geography the research was aimed at hydrology of the Slovak karst. Research in Chemistry focused on synthesis and properties of new compounds with biological activity, new materials and new analytical methods. Research in Informatics was concentrated on fuzzy techniques, neural networks, logical programming and preparation of web-university, in Mathematics it followed the ideas of graph theory, algebraic structures, differential equations and topology and in Physics it was concentrated on development of new magnetic materials, theoretical and experimental research of low-dimensional magnetism and quantum liquids at ultra-low temperatures, nuclear collision studies and photodynamic effect. The research at the Institute of Social Sciences dealt with problems of health, quality of life and integration of health disadvantaged peoples. The research was also carried out in the fields of theory of teaching of biology, chemistry, physics and mathematics. High percentage of the scientific outputs is done in the co-operation with foreign universities or research facilities. Graduates of the Faculty find positions not only as researchers and secondary school teachers but they can successfully work in the business sphere and public administration.

Faculty of Science of P. J. Šafárik University in Košice is included in the group of research faculties, which put strong accent on research as an integral part of their mission. Multidisciplinary character of the Faculty is a good prerequisite for interdisciplinary approach and integration of scientific activities. After entering into European structures the priorities of the Faculty are integration into European research area, improving the quality of scientific outputs and PhD study, increasing the stream of financial sources for scientific activities, re- building of research and information infrastructure of the Faculty and extension of services in community, business, research, developmental, industrial and agricultural facilities in Slovakia. In 2005, the Faculty has continued to improve the quality of several excellent research laboratories: Laboratory of NMR spectroscopy, Laboratory of spectral methods and Laboratory of structure analysis of biomacromolecules (Institute of Chemistry), Laboratory of flow cytometry and Laboratory of cell cultures (Institute of Biology), Laboratory of low temperature physics, Laboratory of biophotonics and Laboratory of advanced computer technologies (Institute of Physics) as well as the Laboratory of GIS (Institute of Geography). In these and other laboratories worked more than 220 university teachers and researchers together with about 60 doctoral students. This staff is involved in up to 130 scientific projects supported by both, grants for fundamental research from the Slovak grant agencies: Slovak Grant Agency for Science (VEGA), Slovak Agency for Science and Technology (APVT), Slovak Cultural and Educational Agency (KEGA), and foreign sources of funding such as COST Agency, DAAD (Germany) and other institutions. Moreover, young researchers were supported by internal grant systems (VVGS) at the university as well as faculty level. In 2005, the University and Faculty supported 11 and 17 VVGS projects, respectively. Excellence in research measured by international standards is a first objective of our research teams. In applied research, the main attention is paid to pharmaceutical, pharmacological, chemical and material research. Continuous increase in funding sources for research is caused by the growing activity and comes from research grants and contracts. It exceeds the average grant income of the Slovak universities, year after year it becomes more

Selected Results

1/9205/02 (prof. E. Mišúrová): Misurova E., Sanova S, Balentova S.: Effects of preconceptional gamma irradiation of rat males on the development of brain.The influence of irradiation of rat males with sublethal dose of gamma radiation 25 or 80 days before mating with control females on brain development in F1 generation progeny was investigated. We found out the decrease in mitotic activity and increase in occurence of chromosomal aberrations (chromosomal bridges) in embyos and brain (hemispheres and little brain) of youngs. Effects transferred to progeny from irradiated spermatids (by irradiation of males of F0 generation 25 days before fertilization) were more marked as effects transferred from irradiated spermatogonia (by irradiation 80 days before fertilization). Our findings we consider as a manifestation of increased genome instability induced in the progeny by paternal irradiation.

MVTS - COST 843 WG3 (prof. E. Čellárová): Variability of hypericin content in four lineages derived from in vitro regenerated Hypericum perforatum L. somaclones of different ploidy level (diploid and tetraploid) growing during successive years and the same season was studied. Flowcytometric seed screen revealed that diploid plants were obligate sexuals, while tetraploid plants were facultative apomicts. Comparison of hypericin content in diploid and tetraploid plants revealed that diploids had higher content of hypericins than tetraploids when growing during successive years but this correlation was not confirmed when growing during

P. J. Šafárik University in Košice, Faculty of Science, Annual Report 2005 31 the same season. Broad DNA variability obtained with 7 non-specific VNTR primers was detected in diploid plants. A unique amplification profile of each plant confirmed the sexual mode of reproduction of diploids. VNTR analysis of tetraploids showed prevalence of apomictic seed formation. The identic (J.Koperdáková et al., Proceedings of the COST 843 Final Conference, COST 843 and COST 851 Joint Meeting, Stará Lesná, 28-3.06.2005 (2005) 285-286)

1/0441/03 (doc. Ľ. Kováč): The project was focused on the diversity of arthropod communities of two ecologically different subterranean locations of the Slovak Karst. The study of the microbial communities (in co-operation with the Institute of Soil Biology CAS, České Budějovice) contributed to understanding of interactions between Arthropoda and their abiotic and biotic environment. High diversity of cave microflora and arthropods of the Domica Cave is attributed to larger cave system, greater variety of microhabitats, more intensive communication with above-ground through water streams and to human activity The latter influence is apparent within the show route of the cave and adjacent halls and passages and is documented by diverse communities of organisms with considerable share of euryvalent or troglophilous arthropod species, whereas specialized cave forms (troglobites) totally absent

APVT-20-003704 (prof. E. Čellárová): Within the cryobiological study the shoot-tips from in vitro cultured Hypericum perforatum L. genotypes were subjected to assessments of developmental competence, genetic stability, and biosynthetic ability to identify critical points during cryopreservation. Survival rate, chromosome number stability, alteration in VNTR sequences and hypericin content were evaluated, in plants after pre-culture, and two subsequent cryogenic steps (cryoprotection and cooling) and those recovered from cryopreserved meristems. Pre-culture and cryoprotection treatments, did not reveal any significant differences, in these studied characteristics. Genetic stability was assessed by chromosome counts and analysis of variability in the VNTR sequences. No changes in chromosome number were detected in comparison with the untreated control but minor alterations were revealed in non-coding sequences.

SR/ČR 046/2004 (R. Oriňáková): The detailed mechanism of electrolytical deposition of Ni coating on paraffin impregnated graphite electrode from chloride electrolyte was proposed. Positively-charged NiCl+ ions were found to be the elctroactive particles in the reduction mechanism. Kinetically-controlled adsorption/desorption processes of various species were confirmed using elimination voltammetry. The presence of boric acid at a sufficiently high concentration inhibits the deposition of Ni and improves the morphology and adhesion of the deposited Ni layer.

1/2118/05 (R. Oriňáková): The anomalous codeposition was confirmed for electrochemical deposition of Ni-Co alloys on Fe powder using cyclic voltammetry with a paraffin impregnated graphite electrode as a working electrode. The rate of binary alloy deposition increases with increasing cobalt ions concentration but it decreases with increasing nickel ions concentration in electrolyte solution. The optimal suspension density for the charge transfer in the fluidised bed electrode was determined during electrolytic coating of iron powder particles with binary Ni-Co layer by EIS measurements. The conduction of the electric current through the dispersed phase of the fluidised bed for studied range of suspension density was explained to be due to the convective mechanism.Conditions for Cu/Ni-Cu multilayer coatings preparation were optimised by the study of polarization curves of single electrolytes, consisting one

The thermodynamic stability of the zinc(II) macrocyclic (1,4,7,10 – tetraazacyclododecane) complexes with heterocyclic ligands in dependence of pH in aqueous solution was determinated. The structure of some complex compounds was studied by single crystal XRD.

1/2470/05 (doc. I. Potočňák): 1. Several compounds of Cu(L)2Pt(CN)4 type were prepared (L are bidentate amine ligands) and crystal structures for compounds with L = ethylenediamine and N,N-dimethylethylenediamine were solved. Magnetic properties of these compounds have been investigated with the aim to compare these results with the results obtained for Cu(L)2Ni(CN)4 compounds.2. Known crystal structures of several Cu(II) compounds with dicyanamide and nitrosodicyanmethanide revealed ionic character of these complexes. The shape of coordination polyhedra in these complexes has been studied with the aim to reveal reasons of different deformation of this shape.3. Biological activity for Cu(II) compounds with dicyanamide has been studied. The obtained results indicate antibacterial and cytostatic activity of these compounds.

P. J. Šafárik University in Košice, Faculty of Science, Annual Report 2005 49 following result: We design a first in-place algorithm for sorting an array of size n that performs, in the worst case, at most O(n.log n) element comparisons and O(n) element transports. This solves a long-standing open problem, stated explicitly, e.g., in [J.I.Munro and V.Raman, Sorting with minimum data movement, J.Algorithms, 13, 374-93, 1992], of whether there exists a sorting algorithm that matches the asymptotic lower bounds on all computational resources simultaneously.

VEGA 1/0385/03 (prof. P. Vojtáš)

Publication [Krajči S.: A generalized concept lattice, Journal of IGPL 2005 13(5) 543-550] contains the following result: We describe a new approach to fuzzify a concept lattice and we show that it is a generalization and common platform for so far known approaches: a classical crisp Ganter & Wille case, a fuzzy Pollandt and Bělohlávek’s one and an one-sided fuzzy concept lattice. We define appropriate (symmetric) mappings and show that they form a Galois connection. Moreover we show that these mappings generate a complete lattice.

1/2024/05 (Marián Kulla): In the first part of the project we were collecting the literature and sources of data and basic information about the selected region. We were joing cooperation with Statistical office, other offices of the government, with the office of the Mayor of Košice, Magistrate of the city, regional government, SA ŽP and others. We were starting the terrain research, which was oriented on localisation of buseness activities in the regional centre, Košice, in the close surroundings of the city (specifically Košice IV region). We are observed development of the industry in the period of transformation and possibilities of recreation for Košice region too. The results were published on various conferences, science magazines and papers in Slovakia and abroad. (KULLA, M. 2005: Priemysel Košíc – minulosť, súčasnosť a budúcnosť.

Selected Results

1/0423/03 (doc. D. Studenovská): Generators of the clone of all compatible functions on bounded distributive lattices were described. This result was generalized for arbitrary distributive lattices (Order, to appear). There were found necessary and sufficient conditions for the existence of the subalgebra extension of one partial monounary algebra by means of another one; a constructive description of the extension is made (Czechoslovak Math.J., to appear). The notion of the weak factor of a lattice was introduced; the relation of this notion to the notion of an almost principle ideal was studied. There were found necessary and sufficient conditions under which a sublattice of a lattice is its weak direct factor (Math. Slovaca, to appear). There was shown that the Cauchy completion exists for each Archimedean l-group and that it is an l-subgroup of the Dedekind completion of the group (Math. Slovaca, to appear).

1/0424/03 (prof. S. Jendroľ): The development of the theory of light graphs has been contributed. It has been proved that every 3-connected graph G containing a path on k vertices (of order at least k) embedded into a surface of Euler characteristic χ contains also a k-vertex path (a connected subgraph of order k) maximum degree of which in G is bounded by a constant that depends only on k and χ. The constant has been exactly determined. Magic line graphs of general graphs have been characterised. Some bounds for the number of edges in supermagic graphs have been also established. New results concerning the structure of the lattice of additive hereditary properties of graphs and uniqueness of a factorisation of reducible properties into irreducible factors have been obtained. New results on achromatic

P. J. Šafárik University in Košice, Faculty of Science, Annual Report 2005 62 invariants of specific graphs and on the existence of (5,q)-fulleroids with tetrahedral group of symmetries have been obtained.

1/0426/03 (doc. J. Džurina): Two infinite sequences of oscillation criteria for self-adjoint second order differential equation of the form (r(t)u'(t))'+p(t)u(t)=0 have been derived. One of them deals with the case when this equation is in canonical form (certain improper integral is divergent), and the other with the case when the equation is in non-canonical form (the same improper integral is convergent). There have been found differential equations for which the obtained sequences allocate such property that consecutive term of the sequence is better (more sensitive) than foregone one for detection of tested property. (J. Ohriska CZECHOSLOVAK MATHEMATICAL JOURNAL 55(2005) 349-363)

1/0427/03 (prof. L. Bukovský): It has been stated (on the basis of own previous results) the conjecture that every permitted set of trigonometric thin sets is small in a topological sense (perfectly meager), hence the existence of large permitted sets is undecidable in ZFC. A combinatorial characterization of relationships between such sets has been found and has enabled to prove this conjecture for Arbault sets and then for another trigonometric thin sets. A different proof of these results has been obtained by a strengthening of Erdős – Kunen – Mauldin theorem on so called additive sets. The mentioned results have been extended to systems generated by analytic groups of reals. Distributive properties of forcings of Sacks type have been examined. Some modifications of Scheepers' conjecture on equivalence of properties S1(Γ,Γ) and wQN have been proved. Ith has been shown that the heredity of several properties of topological spaces is equivalent to a classical property σ.

3/3007/05 (doc. D. Šveda): The analysis of educational content in viewpoint of LMS usage has been performed. The following e-learning courses have been created: 1. An application of IT into mathematics teaching – a compulsory subject for future mathematics teachers. The e- course enables to manage handled problems through an independent study. 2. Features of elementary functions and basics of differential calculus – an assistance course to the compulsory subject Informatics for mathematics teachers. 3. The club of mathematics teachers – a continuous yearly education of mathematics teachers. The administration of the course with e-content and students' outputs are in Moodle. 4. The didactics of mathematics – a compulsory subject for future mathematics teachers. Providing study materials and students' works are in Moodle. There have been created general models of solving cognitive tasks and problems, which fulfil claims of quality of e-tools: interactive help and feedback.

Selected Results

1/0429/03 (doc. V. Lisý): A theory has been built that joins the Rouse and Zimm models of the dynamics of polymers in solution and takes into account the hydrodynamic interaction between the polymer coils. Based on it the relaxation modulus determining the rheological properties of polymeric liquids has been found and the experiments in which the motion of individul monomers within DNA coils was directly observed for the first time have been interpreted. (J.Tóthová et al., CZECHOSLOVAK JOURNAL OF PHYSICS 55(2)(2005) 221- 227, V.Lisý et al., http://xxx.lanl.gov/abs/cond-mat/0509398 (2005) )

1/0430/03 (prof. A. Feher): Specific heat analysis of the magnetic contribution in NaxCoO2 using the Heisenberg approach suggested that the dominant contribution to the specifc heat in the region of short-range ordering is mediated by quasi-2D antiferromagnetic clusters perpendicular to the Co-O layers. The process is connected with a phase separation in the system on mesoscopic scale. (A.Zorkovská et al., PHYSICAL REVIEW B 72(13)(2005) 132412-1-132412-4)

1/1021/04 (doc. P. Kollár): Investigating of the influence of ball-milling on the structural, thermal and magnetic properties of CoFeZrB and CoFeSIB alloys (milled at room temperature and at liquid nitrogen temperature) was found that:In the case of CoFeZrB alloys during ball-milling (without cooling in liquid nitrogen), the inner temperature in the vials increases in favour of the creation of crystallites in the powder samples. This ”partial” crystallization has subsequent influence on the magnetic and thermal properties of ball-milled powders and thus, it can also influence the properties of the final compacted samples.In the case of CoFeSiB samples, the increase of the ball-to-powder ratio led also to the increase of the occurrence of crystallites in the sample. (J.Degmová et al., CZECHOSLOVAK JOURNAL OF PHYSICS 55(7)(2005) 791-801)

1/1020/04 (prof. G. Martinská): The experiment with polarized deuteron beam was performed at energies 140, 200 and 270 MeV at RIKEN, Japan, in December 2000. The high- momentum structure of the 3 He , 3 H and deuteron was investigated. For this purpose the angular dependence of the tensor and vector analyzing powers were measured for the reakcions d + d -> 3 H + p a d + d -> -> 3 H e + n. The results on the tensor Axx, Ayy and vector Ay analyzing powers at 270 MeV were published. (M.Janek et al., INTERNATIONAL JOURNAL OF MODERN PHYSICS A 20(2 -3)(2005) 646-648)

P. J. Šafárik University in Košice, Faculty of Science, Annual Report 2005 74 1/1019/04 (doc. P. Sovák): The influence of Al content in FINEMET alloys has been studied. Structural investigations and magnetic measurements confirmed that small adition of Al (up to 3%) causes strengthening of exchange interactions in as-quenched samples whereas for x more than 3% was observed owing dilution. Nanocrystalline alloys after optimal annealing showed presence of Al in FeSi grains.The influence of Co content on the structure and magnetic properties of (Fe-Co)CuNbSiB alloys has been investigated. Co plays significant role at primary crystallisation when α-FeSi(Co) grains growth for lower Co content and grains of fcc β-Co for higher Co content (up to x=0.7). (T.Szumiata et al., JOURNAL OF MAGNETISM AND MAGNETIC MATERIALS (295)(2005) 37-47, G.Pavlík et al., 17th Soft Magnetic Materials Conference, Book of Abstracts,Bratislava, Sept.2005 (2005) B-D-32)

1/1017/04 (prof. P. Vojtaník): Perminvar effect influenced by atom-pair reorientations in the amorphous and nanocrystalline HITPERM type Fe44,5Co44,5Zr7B4 alloy was experimentally studied. Considerable influence of the annealing and the time-thermal domain wall stabilization on the AC susceptibility, the perminvar critical fields and their stability was found. The annealing between 150-350 °C initiates the domain wall mobility and AC susceptibility increasing accompanied by the free volume and internal stress release in the alloy. At the same time the critical field HCR increases. The record value of the HCR =200 Am–1 obtained at 350 °C is a result of the optimal directional ordering of atom pairs in the amorphous alloy. The nanocrystallization makes the susceptibility and the critical field decreased. The given results are applicable in electronics and other technical sectors.

2/4014/24 Parimucha ( D. Chochol): The interstellar extincion was determined for a set of 52 symbiotic stars based on the analysis of the shape of their ultraviolet continuum (Š.Parimucha et al., PUBLICATIONS OF THE ASTRONOMICAL SOCIETY OF THE PACIFIC (349)(2006) 309-313)

MVTS Nem/Slov/BMBF/04 (prof. G. Martinská): Several processes of meson production in proton-deuteron collisions have been measured simultaneously using a calibrated magnetic spectrograf. Among these processes, the h meson is seen clearly as a sharp missing-mass peak on slowly varying background in the p + d -> 3He + X reaction. Knowing the kinematics of the other reactions with well determined masses, it is possible to deduce a precise mass for the h meson. The final result, m(h) = 547.311 ± 0.028 (štat.) ± 0.032 (syst.) MeV/c2 is significantly lower than that found by the recent NA48 measurement, though is consistent with values obtained in earlier counter experiments. (M.Abdel-Bary et al., PHYSICS LETTERS B 619(2005) 281-287)

20/2004 VVGS UPJŠ ( J. Fuzer): Co70.3Fe4.7Si10B15 and Co56Fe16Zr8B20 bulk amorphous samples were prepared by hot pressing of powders obtained by ball milling of pieces of melt-spun ribbons. Hot pressing followed by heat treatment allows to reduce the stress introduced into the material during ball milling and consolidation. This method enables the preparation of bulk samples with significantly larger dimensions than specimens prepared by copper mold casting and with very good soft magnetic properties comparable to those of the corresponding as-quenched ribbons were prepared.

CERN-Experiment NA 57 ( I. Králik): Experiment NA57 on CERN SPS studies strange hyperon production. Yields of hyperons and antihyperons Lambda, Ksi and Omega were obtained in Pb-Pb, proton-Pb and proton-Be collisions at 160 GeV/c/nucleon in central

P. J. Šafárik University in Košice, Faculty of Science, Annual Report 2005 75 rapidity regime and medium transversal impulses as a function of collision centrality. In Pb- Pb collisions increased production of strangeness is observed, compared to proton-Be collisions. Production increases with the centrality of collision and with the growth of hyperon strangeness. For Omega hyperons in central Pb-Pb collisions increase of factor 20 is observed.. (F.Antinori et al., JOURNAL OF PHYSICS G-NUCLEAR AND PARTICLE PHYSICS 31(2005) S919-S927, F.Antinori et al., JOURNAL OF PHYSICS G-NUCLEAR AND PARTICLE PHYSICS 31(2005) 1345-1357)

1/2009/05 (prof. A. Bobák): Thermodynamic properties of a tetramer ferro-ferro-antiferro- antiferromagneticIsing-Heisenberg bond alternating chain are investigated by the use of an exact mapping transformation technique. Exact results for the magnetization, susceptibility, and specific heat in zero as well as nonzero magnetic field are presented and discussed in detail. The results obtained from the mapping are compared with the relevant experimental data of Cu(3-Clpy)2(N3)2, where 3-Clpy indicates 3-Chloropyridine.Nontrivial quantum plateau to be observed at half of the saturation magnetizationin the magnetization process of this one-dimensional coordination polymer, has been explained as a typical feature of the quantum ferrimagnet. (J.Strečka et al., PHYSICAL REVIEW B 72(2)(2005) 024459-1- 024459-11)

1/2007/05 (doc. S. Vokál): In the frame of BECQUEREL project the scanning of photoemulsion chambers irradiated by relativistic nuclei 11B on the Nuclotron in Dubna has been done. 542 inelastic collisions have been found on 7141.3 cm of relativistic nuclei tracks. Mean free path is 13.2+-0.6 cm. In 320 collisions polar and azimuthal angles and charges of fragments of 11B have been measured. Measurement of pbeta and charges on 46 tracks of simply charged fragments of 11B have been done to identify pions. For the first time the measurements of pbeta also on double charged fragments paths have been done to identify 3He and 4He. Along with these the new material have been measured, where the fotoemulsions have been irradiated be 3He nuclei. The new experimental results on multiplicity of charged particles, multifragmentation of light nuclei and nonstatistical fluctuation in relativistic collisions have been obtained.

APVT-20-005204 (prof. A. Feher): Detailed analysis of thermodynamic quantities and ESR spectra of the compound Cu(tn)Cl2 was performed. The material may represent 2d Heisenberg antiferromagnet on a triangular lattice with spatial anisotropy of exchange coupling. Exchange interaction in the studied system is mediated predominantly by network of hydrogen bonds. The analysis of the temperature dependence of the correlation length indicates potential reduction of staggered magnetization which could be caused by spin frustration. (V.Zeleňák et al., INORGANIC CHEMISTRY 45(4)(2006) 1774-1782)

APVT-20-008404 (doc. P. Kollár): The structure and magnetic properties of Co70.3Fe4.7B25 alloy prepared in the form of ribbon were investigated during the long-time ball milling. The structure phase composition of powder samples was stable and did not change during the whole milling process. After 1550 hours of milling the nanocrystalline (Co,Fe)3B powder was formed. Observed behavior of magnetic properties is explained in terms of reduced particle size and superparamagnetic phenomenon.

APVT-20-011704 (doc. S. Vokál): The main physical results achieved within the project based on STAR experiment can be summarized as follows: It has been found inevitable to correct many concepts concerning the predicted properties of the Quark-Gluon Plasma (QGP)

P. J. Šafárik University in Košice, Faculty of Science, Annual Report 2005 76 from the first years of the BNL and CERN heavy-ion programme and even from the recent years. QGP does not behave like a gas, i.e. like the bulk of weakly interacting quarks and gluons, but rather like a fluid with very low viscosity, despite its extremely high density. It flows so freely it even approaches an ideal fluid. It should be emphasized the notion "ideal fluid" denotes a fluid in its classical interpretation and not a superfluid whose superviscosity and other properties are dictated by the laws of Quantum Mechanics. These conclusions were supported also by the another three experiments operating on RHIC collider. (J.Adams et al., NUCLEAR PHYSICS A 757(1-2)(2005) 102-183)

APVT-51-016604 (doc. P. Samuely): Anomalous low temperature behavior of specific heat and magnetic susceptibility has been found in the NaxCoO2 system. The anomaly suggests that the system does not behave according to the Landau theory of metals, but it ranks among the permanently expanding group of unconventional non-Fermi liquids. Deeper analysis signalizes the existence of novel quantum states in the system, the quantum Griffiths phases. (A.Zorkovská et al., 15.

Selected Results

1/1408/04 (doc. O. Orosová): Only one third of respondents reported willingness to participate in prevention program, while 16% of respondents refused participation, 28% were not decided and 24% did not answer on this question. More males than females refused to participate. Adolescents of higher socio-economic status (SES) were more likely to refuse participation or not answer the question on motivation in comparison to those from lower

P. J. Šafárik University in Košice, Faculty of Science, Annual Report 2005 85 SES. Smoking decreased and drunkenness increased the probability of not answering the question on participation. Additional analysis within those already participating in the current program, showed that important incentives for joining the program are a social motivation, an opportunity to meet new people and make new friends; external benefits (e.g. possibility to obtain credits for the study) and peer influence (Humeníková et al. 2005) (M.Humeníková et al., 13th EUPHA conference "Promoting the public's health: reorienting health policies, linking health promotion and health care" Graz, 10-12 November 2005.

APVT-20-028802 ( A. Madarasová Gecková): In the sample of 883 students (373 boys and 510 girls, mean age 15.8 years), adolescents’ strength of reasons for smoking was explored. The higher the smoking frequency, the higher the rating of strength of reasons for continuing smoking in the past and for actual smoking. Higher smoking frequency increased the tendency to use smoking as a coping strategy in all the explored situations. Effective secondary prevention should be targeted at the potency of a variety of adolescent reasons for continuing smoking in the past and for actual smoking (Orosová et al., 2005).

The year 2004 was used for preparation; from November 2004 on the data collection is in progress. 2005 was used for data collection as well; one review article was written (Socioeconomic differences in psychosocial factors of coronary heart disease – Z.Skodova). Two more articles were commenced. The first one analyses the medical risk factors and severity of coronary artery disease in the Roma versus non-Roma; the second one evaluates the predictors of self-reported health in patients indicated for selective coronaroangiography. Preliminary results were published at international and national conferences (Graz, Portorož, Bratislava).

105/2002 Groningen ( A. Madarasová Gecková): Health status of three age groups: 1st grade secondary school students, 3rd grade students and secondary school leavers were compared. Females rated their health worse than males on all six indicators. For males, younger age was associated with better health For females, the pattern of age differences were not so consistent (Šléšková et al. 2005a).Parental long-term unemployment (especially of fathers) negatively affects adolescents’ health (2836 respondents aged 14 to 22), and this negative effect remains even when the effect of social class and financial strain is taken into account (Šléšková et al. 2005b, Šléšková et al. 2006a – in press). Our results indicate that father’s employement status is more important for predicting the health of Slovak adolescents

(2005) 36-39)

49/2002 Groningen ( A. Madarasová Gecková): Changes in health and health related behaviour in cohort of adolescents between 1998 and 2002 were explored by research team working on project „Inequalities in health among Slovak adolescents – cross-sectional and longitudinal study“ (49/2002). Changes in health related behaviour patterns in the period between late adolescence and early adulthood are related to gender regarding alcohol consumption, use of marijuana, and insufficient physical activity. In males no significant socio-economic gradients in change of all four health related behaviour indicators were found. Females with higher SES reported greater increase in alcohol consumption and marijuana use; those with lower SES a decrease in physical activity.

95/2004 Groningen (doc. O. Orosová): The effect of behavioural (being drunk, smoking sex before age of 16) and psychological (self-esteem, well-being, extroversion, neuroticism, religiousness) factors on sexual behaviour were explored among university students. More than two thirds of respondents already have had sexual intercourse. Occurrence of sexually risky behaviour is very high, varies between 22 to 81% of sexually experienced depending on used indicator. Except self-esteem, significant effect of explored factors on occurrence of sexual experience as well as on sexual risk behaviour were confirmed. The predictors of different types of sexual behaviour differ as well as there are gender differences. Our findings indicate the need for health promotion focused on set of unhealthy behaviour instead of single behaviour implemented already in adolescence (Kalina et al. 2005).

106/2004 Groningen ( I. Rajničová): (106/2004) - The project focuses on functional status and quality of life in patients with rheumatoid arthritis (RA) (I. Rajnicova-Nagyova, PhD). In year 2005 one paper concentrating on the impact of pain on psychological well-being in rheumatoid arthritis patients was published in SCI journal with an impact factor. Also a PhD thesis entitled ‘Self-rated health and quality of life in Slovak RA-patients’ was defended at the University of Groningen, the Netherlands. Three more articles are in the process of preparation; they are focusing on psychometric properties of instruments measuring pain and on the predictors of perceived health status in patients with rheumatoid arthritis. (I.Nagyová et al., PATIENT EDUCATION AND COUNSELING (2005) 55-62, I.Nagyová (2005) )

35/2001 Groningen ( A. Madarasová Gecková): In 2005, the project „Inequality in health among Slovak adolescents“ (35/2001) contribute to scientific output with one paper focused on adolescent’s smoking behaviour and one monograph reviewing literature related to socio- economic inequalities in health (Madarasová Gecková 2005). The influence of socio- economic status, parents and peers on the smoking behaviour of adolescents is explored using LISREL analyses. Peers’ smoking is the strongest predictor of adolescents’ smoking. Parents’ smoking behaviour influences adolescents’ smoking directly, but also indirectly through the influence on peers’ smoking behaviour (selection of peer-friends). Socio-economic status influences adolescents’ smoking indirectly through the influence on parents’ and peers’ smoking behaviour (Madarasová Gecková et al. 2005).

P. J. Šafárik University in Košice, Faculty of Science, Annual Report 2005 87 48/2002 Groningen ( A. Madarasová Gecková): The contribution of bullying, school connectedness and self-esteem to psychological well-being were explored among Slovak adolescents as well. Gender, school connectedness and self-esteem significantly influence psychological well-being of adolescents, while self-esteem seems to be the most important determinant of psychological well-being of adolescents (Katreniakova et al. 2005).The significant effects of gender, two from four social skills (ability to manage and express positive feelings and personal limitation) and smoking on mental health of adolescents (n=1023, mean age 14.9 years) were confirmed. Female, respondents characterised by lower social skills and smokers display worse mental health (Sarkova et al. 2005a ).

/2002 Groningen ( I. Rajničová): ( /2002) - The project focuses on biomedical and psychosocial factors related to functional status and well-being in patients with neurological diseases, particularly Parkinson’s disease (PD) (T.Dubayova MSc, E.Havlikova, MD) and Multiple Sclerosis (MS) (M.Krokavcova MSc + M.Gavelova MD). In 2005 the data collection continued; two researchers worked on a review (Personality and patient delay in PD; Self rated health in MS). On the basis of the data analyses four new manuscripts were commenced and preliminary results were published at international and national conferences (Berlin, Graz, Hradec nad Moravici, Bratislava). The manuscripts deal with: fatigue in patients with PD, factors influencing perception of quality of life in patients with PD, mastery in patients with MS and functional status of patients with MS.

144/2004 Groningen (J. Rosenberger): (144/2004)- Project is focusing on functional status and quality of life among patients after kidney transplantation (J.Rosenberger, MD). In 2005 the data collection continued, but at the same time already collected data were analyzed and first findings were published at national and international conferences (Graz,Bratislava). Three manuscripts were published in SCI journals with IF; the occurrence of adverse effects of immunosuppression and its possible determinants (Clinical Transplantation); as well as the influence of adverse effects of immunosuppression on compliance in transplanted patients (Transplantation International); and the determinants of Quality of Life in transplanted patients (Nephrology, Dialysis and Transplantation). One article focussing on predictors of perceived health status in patients after kidney transplantation was accepted for publication (Transplantation).
