UTJECAJ MAKROEKONOMSKIH FAKTORA NA CIJENE NEKRETNINA: DOKAZI IZ CRNE GORE

The real estate market, as one of the most volatile economic sectors, is a key research topic for many authors. Regardless the significance of this topic, no previous research has been conducted to evaluate the factors which influence the price of real estate in Montenegro. Therefore, the objective of this study is to clarify whether the trend in real estate prices in Montenegro can be explained by macroeconomic fundamentals such as GDP, the inflation rate, interest rates on mortgages, take-up of mortgages, the unemployment rate, the average net salary, the current account deficit and constructing activity and to determine which of them is the most important in explaining the price trend for this market. The applied methodology is based on the model averaging technique, which has not been used in previous research on this topic; it enables the research to focus on the relevant results despite the short time series and the large number of independent variables. The results obtained point to the fact that price trends in real estate are best described by and most closely align to GDP. Apart from GDP, net salary, the unemployment rate as well as the take-up of mortgages and their interest rates are shown to be significant as variables, which determine price trends within the real estate market.Tržište nekretnina, kao jedan od najvolatilnijih gospodarskih sektora, za mnoge je autore ključna tema istraživanja. Ipak, bez obzira na značaj ove teme, nijedno istraživanje nije provedeno da bi se ocijenili faktori koji utječu na cijenu nekretnina u Crnoj Gori. Stoga je cilj ove studije razjasniti može li se trend cijena nekretnina u Crnoj Gori objasniti makroekonomskim fundamentima kao što su BDP, stopa infl acije, kamatne stope na stambene kredite, stambeni krediti, stopa nezaposlenosti, prosjek neto plaće, defi cit tekućeg računa i građevinske aktivnosti te odrediti koja je od njih najvažnija u objašnjavanju kretanja cijena za ovo tržište. Primijenjena metodologija temelji se na model averaging tehnici koja se nije koristila u prethodnim istraživanjima na ovu temu; to omogućuje da se istraživanje usredotoči na relevantne rezultate unatoč kratkim vremenskim serijama i velikom broju neovisnih varijabli. Dobiveni rezultati ukazuju na činjenicu da kretanja cijena nekretnina najbolje opisuju i najviše se podudaraju s BDP-om. Osim BDP-a, neto plaće, stopa nezaposlenosti kao i stambeni krediti i njihove kamatne stope pokazali su se značajnim kao varijable koje određuju kretanja cijena na tržištu nekretnina

Genetic markers and selection of the economically important traits

Molekularna genetika je pružila mogućnost za poboljšanje selekcije i produkcije kod domaćih životinja primenom genetičkih markera. Primena DNK markera imala je revolucionarni uticaj na projekte mapiranja gena i razvoj animalne genetike. Istraživanja su usmerena na identifikaciju gena odgovornih za variranje osobina, kao i na detekciju genetičkih markera koji se mogu koristiti u programima ukrštanja i selekcije. Tehnologija genetičkih markera, kao što je selekcija vezana za markere (MAS), identifikacija pedigrea i genska introgresija, mogu se primeniti u oblasti selekcije kod stoke. Selekcija vezana za markere (MAS) koristi informacije o genetičkim markerima za predviđan je produkcionog potencijala i omogućuje dodatne informacije za poboljšanje efikasnosti selekcije. Cilj je genetičko usavršavanje selekcije životinja i njihove produkcije. Zbog toga se genetički markeri vrlo intenzivno koriste za procenu vezanosti sa genima koji imaju uticaj na osobine od ekonomskog značaja. Ove osobine uključuju genetički uslovljene varijante proteina mleka, otpornost na bolesti i stres, kao i osobine koje utiču na kvalitet mesa, rast i osobine karakasa. Primena selekcije bazirane na tehnologiji markera omogućiće maksimalno poboljšanje ekonomske vrednosti kod domaćih životinja. .Molecular genetics made available genetic markers as a powerful tool for genetic improvement of animal selection and production. The development of DNA-based markers has had a revolutionary impact on gene mapping and animal genetics. The research is focused on the identification of the genes responsible for the variability of traits and detection of the genetic markers useful for selection and crossbreeding programs. Genetic marker technologies, such as marker-assisted selection (MAS), parentage identification and gene introgression can be applied to livestock selection programs. Marker-assisted selection (MAS) is a method which uses information on the location of markers to predict production potential and to improve the efficiency of selection. The major goal is genetic improvement of animal selection and production. Genetic markers are used to estimate the association with economically important trait loci. Traits of economic interest include milk protein genetic variants, milk production, disease and stress resistance and meat quality, growth and caracass traits. Selection based on marker technologies will allow maximum improvement in the economic value of domestic populations

Compressive strength and hydrolytic stability of fly ash based geopolymers

The process of geopolymerization involves the reaction of solid aluminosilicate materials with highly alkaline silicate solution yielding an aluminosilicate inorganic polymer named geopolymer, which may be successfully applied in civil engineering as a replacement for cement. In this paper we have investigated the influence of synthesis parameters: solid to liquid ratio, NaOH concentration and the ratio of Na2SiO3/NaOH, on the mechanical properties and hydrolytic stability of fly ash based geopolymers in distilled water, sea water and simulated acid rain. The highest value of compressive strength was obtained using 10 mol dm-3 NaOH and at the Na2SiO3/NaOH ratio of 1.5. Moreover, the results have shown that mechanical properties of fly ash based geopolymers are in correlation with their hydrolytic stability. Factors that increase the compressive strength also increase the hydrolytic stability of fly ash based geopolymers. The best hydrolytic stability of fly ash based geopolymers was shown in sea water while the lowest stability was recorded in simulated acid rain.

Presence of histopathological premalignant lesions and infection caused by high-risk genotypes of human papillomavirus in patients with suspicious cytological and colposcopy results: A prospective study

Background/Aim. In patients with premalignant cervical lesions, human papillomavirus (HPV) infection, at any moment, may be spontaneously eliminated, or may persist or transform cervical epithelium from a lower to a higher degree. Due to that, it is necessary to wisely select the patients who are at high risk of cancer development. The aim of the study was to establish the interdependence between a suspicious Papanicolaou (Pap) test and colposcopy with the infection caused by high-risk genotypes of human papillomavirus and the presence of premalignant cervical lesions. Methods. This prospective study used cytological, colposcopy, real-time polymerase chain reaction (PCR) of high-risk genotypes of human papillomavirus and histopathological analysis of cervical biopsy specimen. Out of 2,578 female patients sent to cytological analyses in Clinical Center of Montenegro, during 2012, 2013 and 2014, the study included 80 women who had to submit their biopsy specimens due to a suspicious Pap test and atypical colposcopy results. Results. In the group of 80 (3.1%; n = 80/2,578) of the selected female patients with suspicious Pap test and colposcopy, 2/3 or 56 (70%) of them had cervicitis, and 1/3 or 24 (30%) had cervical intraepithelial neoplasia. The most common type in cervical intraepithelial neoplasia was HPV16 in 8 female patients, ie 61.53% out of the number of infected, or 33.33% out of the total number of premalignant lesions. Conclusion. Patients with suspicious Papanicolaou test, colposcopy results and infection which is caused by high-risk HPV infection (HPV 16 in particular) often have premalignant cervical lesions. In these cases, histopathological confirmation of lesions is mandatory, since it serves as a definitive diagnostic procedure

Does age influence the quality of life in children with atopic dermatitis?

BACKGROUND:Atopic dermatitis (AD) is one of the most common childhood skin diseases that can affect the quality of life (QoL) of children. The QoL of Montenegrin children with AD has not been sufficiently explored. The aim of this study was to assess their QoL with special emphasize on age differences. METHODS:This cross-sectional study included children with AD seen at the Clinic of Dermatology and Venereology, Clinical Center of Montenegro (CCM) in Podgorica between August 2017 and July 2018. The QoL was assessed with the Infants' Dermatitis Quality of Life Index (IDQOL) and the Children's Dermatology Life Quality Index (CDLQI). Disease severity was measured by the Three Item Severity (TIS) score. RESULTS:A total of 386 children with AD aged from newborn to 16 years took part in this study. The mean total score of the QoL was 14.7 in infants (0-4 years old), 19.4 in younger children (5-9 years old), and 16.6 in older children (10-16 years old). Age was in negative correlation with the CDLQI score, leisure domain of the CDLQI and CDLQI sleep, and in positive correlation with the IDQOL child mood. TIS score was in positive correlation with both the IDQOL and CDLQI score. CONCLUSIONS:The QoL measured by CDLQI was more impaired in younger children, whilst IDQOL child mood was more impaired in older infants. The most impaired QoL was seen in children in the age group 5-9 years. Regardless of disease severity, treatment and counseling of children suffering from AD should be tailored specifically to their age
