Preschool institutions in Vojvodina through the elements relevant for the population policy
GavriloviAna
Zbornik Matice Srpske za Drustvene Nauke , 2010, DOI: 10.2298/zmsdn1031473g
Abstract: Unlike other institutions, preschool institutions are the only ones that support and encourage complete psycho-physical and social development of small children. Preschool institutions provide safety and upbringing, as well as take care, educate, socialize, and compensate different upbringing. In addition to the above-mentioned, they also provide necessary food and relaxation space in adequately equipped and set premises for children's upbringing. Preschool institutions have direct contacts with parents with small children, and with children. Therefore, by completing their tasks and carrying out proposed activities they can influence creation of a better ambient for the increase of birth rate. The aim of this article is to analyze the elements of such complex activities in order to review the role of those institutions within the population policy of Vojvodina. It is about the capacities (purposely built and adopted premises) inside and outside of the administrative municipalities, human resources, work activities, work hours, range of children, waiting lists, the ways of identification of needs for the work activities and services provided, as well as the inclusion of those institutions in the population policy of respective municipalities. The article represents a contribution to emphasize the necessity to activate available potentials of the population policy and to search for new solutions. .
Population policy of local self-government: Necessities possibilities and limitation

Zbornik Matice Srpske za Drustvene Nauke , 2006, DOI: 10.2298/zmsdn0621171g
Abstract: Taking into consideration the roles it objectively has, the state is also responsible for the formulation and implementation of population policy. In the process of its articulation, population policy of our state, although not explicitly formulated, continual and consistent, went through various phases of development, but was mostly in the shadow of other policies. In order to be successful, population policy has to be local, too. The need for definition and implementation of local population policy is indicated by insufficiency and inefficiency of government measures, knowledge of determinants of reproductive behavior and social processes, especially society democratization and globalization. The possibilities available are not sufficiently used. The attention is focused on the measures of material assistance, which is understandable in present conditions, while the measures of non-material assistance are almost missing. The paper is pointing out the non-material potentials and the necessity of their activation. The paper also contains the results of an empiric research carried out by interviewing the presidents of the population policy committees within municipal assemblies in the Autonomous Province of Vojvodina, thus providing the picture of the present situation, and knowledge of their positions, opinions and suggestions for the better use of potentials and overcoming of limitations in population policy.

Abstract: Population should be in the central focus of local community institutions and the local community may constitute its population policy which will supplement state population policy measures, considering the local specific various traditions, values and models of living. The paper's basic goal is to critically perceive the characteristics, significance and role of local self-governments in the current population policy of Serbia. Social situation and social policy characteristics in Serbia are analyzed in the context of the population policy. It is pointed out that poverty, unemployment, the economic crisis, the process of privatization, the issue of system decentralization and social expectations of the population, as current expressions of transition, all have a consequence on the demographic development and population policy. A critical estimation of the activities in the field of population policies which are carried out by local and provincial self-governments in Serbia in the last decade are brought into focus, with a special review to the activities of provincial and local governments in the Autonomous Province of Vojvodina. As a result of the analysis it is pointed out that the population and social policy measures have been separated since the year 2000 and that they have been directed only to stimulating births and not child raising and that solutions regarding maternity leave brought improvements, however shortened maternity leave for the third child. The new conception of the population policy brought a whole series of restrictions such as: suspension of aid for newborn essentials; discontinuance of the right to maternity allowance; abolishing of compensation for preschool expenses for the third child; children’s allowance lost its population measures character along with considerable tightening of the census and decreasing of amount; the activities of preschool facilities have been reduced only to an educational function, and the terms for realizing rights to preschool education for children without parents and children with special needs have been tightened. The authors point out to the values and principles on which a contemporary population policy of local self-governments in Serbia should be established, such as: stability of established measures, a clear message on the needs of society, compatibility and not uniformity with measures of other bodies, compassion and uniformity with aspirations of couples and individuals, respect for the rights and freedom of man, information availability, equality of birth and raising children in measures.

Abstract: Changes in plasma levels of adrenocorticotropic hormone (ACTH) and corticosterone (COTR) of adult male rats exposed to two chronic types of psychosocial stress: isolation and crowding, as well as physical stress i.e. forced swimming and combined psychosocial and physical stress i.e. isolation accompanied by forced swimming, both under basal conditions and in response to immobilization and cold as short-term stressors, were studied. Chronic isolation produced a significant elevation of basal plasma ACTH and CORT, but chronic isolation accompanied by forced swimming produced a significant elevation only in basal plasma ACTH, but not CORT, while chronic crowding and forced swimming did not elevate the basal plasma levels of these hormones. Chronically stressed animals exposed to immobilization or cold show a significant elevation of plasma CORT. No significant differences in plasma CORT between the four chronically stressed groups of rats were recorded. Novel acute immobilization and cold stress produce a markedly increased plasma ACTH in chronic crowding, forced swimming and isolation accompanied by forced swimming rats. These data suggest that chronic isolation seems to be a stronger stressor for rats compared to other chronic stressors.

Abstract: During the late summer of 2007, a severe phytoplasma-like disease was observed for the first time in blackberry plants (Rubus fruticosus), commercial cv. a anska beztrna. Redness and downward rolling of leaves were symptoms observed in three localities in Central Serbia. The presence of Stolbur phytoplasma, belonging to the taxonomic subgroup 16SrXII-A, in diseased samples was confirmed by the PCR - RFLP analysis of 16S rDNA genes and elongation factor Tu (tuf) gene. A sequence analysis of the tuf gene confirmed homology with phytoplasmas stolbur tuf-type II detected previously in Italian grapevines and red clovers in the Czech Republic. This is the first report of Stolbur phytoplasma 16SrXII-A group tuf-type II on blackberries in Serbia.

Abstract: In this study we examined how chronic forced running (CFR) affects the expression of catecholamine biosynthetic enzymes and cAMP response element-binding (CREB) in the adrenal medulla and the weight of adrenal glands of rats. Also, we examined how CFR and additional acute immobilization stress affect the expression of catecholamine biosynthetic enzymes in the adrenal medulla and the concentration of catecholamines and corticosterone (CORT) in the blood plasma. In this experiment we used as a model forced exercise in rats (treadmill running). We used the most advanced method for determining the level of gene expression, Real-time PCR with TaqMan probes, as well as Western blot analysis (ECL). We found that CFR decreases tyrosine hydroxylase (TH), and dopamine-β-hydroxylase (DBH) mRNA and protein levels in the adrenal medulla. The decreased TH and DBH mRNA levels coincide with the reduced expression of CREB in the adrenal medulla and with the reduced plasma CORT level. Additionally, CFR reduces the level of phenylethanolamine N-methyltransferase (PNMT) mRNA, but elevates its protein level in the adrenal medulla and increases the concentration of adrenaline (A) in the plasma. Reduced level of PNMT mRNA in the adrenal medulla coincides with reduced plasma CORT level. The additional acute immobilization stress increases gene expression of catecholamine biosynthetic enzymes in the adrenal medulla, as well as catecholamines and CORT levels in the plasma. The increased synthesis of PNMT enzyme in the adrenal medulla may result in an increased biosynthesis of A under chronic stress conditions. Additionally, increased level of catecholamines in the plasma after chronic physical stress is the allostatic load that may induce numerous diseases and pathological conditions.

Abstract: The effects of diazepam (0.2 mg/kg/ during 21 days, i.p.) on behavior, pituitary-adrenocortical and sympatho-adrenomedullary system of socially isolated and group-housed adult male rats additionally exposed to immobilization, were studied. Social isolation led to a shorter duration of grooming and longer latency to start grooming. Diazepam in social isolated rats reduced incorrect transitions percentage, but the number of grooming bouts, duration and latency to start grooming remained unchanged. Long-term isolation significantly elevated plasma ACTH and corticosterone, while not affecting noradrenaline and adrenaline. Diazepam decreased only plasma ACTH. Social isolation and immobilization significantly elevated all examined hormones. Immobilization of diazepam-treated isolated rats enhanced plasma ACTH , the increase being significantly lower, comparing to isolated vehicle-treated rats. Immobilization significantly increased plasma adrenaline, noradrenaline and corticosterone of diazepam- or vehicle-treated socially isolated rats. No differences in adrenaline, noradrenaline and corticosterone level between these two groups were observed. This indicates that chronic diazepam treatment of socially isolated rats changes some grooming behavior parameters, but insignificantly affects stress-related adrenomedullary and adrenocortical alterations.

Abstract: Enhanced activation of sympathetic neurons during stress results in an increased cardiovascular function. Social isolation is a psychological stress which has deleterious effects on health and represents the most relevant cause of diseases in mammalian species. In this study we investigated the changes in catecholamine biosynthetic enzymes tyrosine hydroxylase (TH), dopamine β-hydroxylase (DBH) and phenylethanolamine N-methyltransferase (PNMT) gene expression and protein levels in the stellate ganglia of naive controls and chronically socially isolated (12 weeks) adult rats and the response of these animals to additional immobilization stress (2 h) by applying TaqMan RT-PCR assay and Western blot analysis. Psychosocial stress produced a significant increase of both TH mRNA (p<0.05) and DBH mRNA (p<0.05) levels in stellate ganglia. The exposure of control rats to acute immobilization significantly increased TH mRNA (p<0.001) and DBH mRNA (p<0.01) levels, while additional immobilization of chronic psychosocially stressed rats expressed no effect on gene expression of these enzymes. Protein levels of TH, and DBH remained unchanged in control and chronic social isolation rats and also after short-term immobilization. The results presented here suggest that psychosocial stress-induced an increase in gene expression of catecholamine biosynthetic enzymes in stellate ganglia and thus may be connected to the increased risk of cardiovascular disease.

Abstract: Recirculating aquaculture is one of the solutions to an environmentally sustainable and economically feasible aquaculture production, and can be established in either urban or rural communities. Controlled conditions enable optimal growth conditions suitable for the species in question during the whole growth process, as well as the shortening of the process itself, when compared to open uncontrolled systems. Recirculating systems are now one of the most researched fields of aquaculture, and biofiltration as the reduction of the poisonous ammonia compounds generated by digestion of proteins, is one of its most important parts. The aim of this study was to stress the importance of biofiltration, and to describe different designs of biofilters. Many biofilters are being used in commercial and research aquaculture facilities with differences in choice of working organism, design, material, price and etc. For the proper choice of biofilter it is necessary to know characteristics of each recirculating aquaculture system, because there are still no strict criteria for categorizing and applying different biofilter designs.

Abstract: The aim of this study was to examine how acute immobilization stress affects the concentrations of catecholamines in the plasma and the expression of the splenic catecholamine biosynthetic enzymes tyrosine hydroxylase (TH), dopamine-Я-hydroxylase (DBH) and phenylethanolamine N-methyltransferase (PNMT) in chronically socially isolated rats. We found that acute immobilization increases the plasma catecholamine levels and splenic PNMT protein levels in chronically socially isolated rats. These results show that acute stress of chronically stressed animals activates the sympatho-adrenomedullary system and increases synthesis of splenic PNMT by 37%, both of which can modulate the immune function.
