PENGARUH JUMLAH SAHAM BEREDAR, IFR, TINGKAT PENGUNGKAPAN INFORMASI WEBSITE DAN HARGA SAHAM PENUTUPAN TERHADAP FREKUENSI PERDAGANGAN SAHAM PERUSAHAAN (Studi pada Perusahaan yang Terdapat pada Indeks Kompas100 Februari-Juli 2015)
The capital market unite the company and investors. In determining which
companies to be selected, investors carry out several analyzes, including analyze
the price and frequency stock trading in the past to estimate the frequency in the
future. Frequency trading is influenced by several factors, including the number
of shares traded, the fundamental factors, the disclosure of information, and stock
prices. Meanwhile, technology (internet) develop very fast and influenced the
form of financial statements via the internet or the website called Internet
Financial Reporting (IFR), while for non-financial information , companies use
websites to reduce asymmetry information about the company. This study aims to
determine the effect of the number of traded shares, IFR, the level of website
disclosure, and the closing stock price toward the frequency of company’s shares
trading.
The data used in this study is a cross section data. This study uses the 94
companies that included in the KOMPAS100 index period from February to July
2015, have a website and apply IFR. Linear regression is used to determine the
effect of the number of traded shares, IFR, the level of website disclosure, and the
stock price toward the frequency of company’s shares trading.
The results of this study indicate that according to the F test, the number of
outstanding shares, IFR, the level of disclosure website, and stock prices affect
the frequency trading (sig. 0.000), while according to the t test, partially only the
number of shares outstanding and the stock price a positive and significant effect
(with sig. 0.000), while IFR (sig. 0.732) and the level of information disclosure
website (sig 0.805) did not significantly affect the company's shares trading
frequency. Meanwhile, according to determination test, the number of outstanding
shares, IFR, the level of information disclosure website and the closing share
price affect the frequency of the company's shares trading amounted to 54.9%
Rezistencija na tetraciklin bakterija mlečne kiseline izolovanih iz tradicionalnih sireva Srbije
Food chain may represent a possible route for the transmission of antibiotic resistant bacteria between human and animal populations. Commensal bacteria originating from food-producing animals can contaminate food and by that means become a part of the complex food microbiota. Commensal bacteria can also serve as reservoirs for the antibiotic resistance genes. Tetracycline resistance in commensal bacteria is well documented and is coded with transmissible genes. Therefore, it is recognized as a model for the monitoring of antibiotic resistance ecology. Homolj, Zlatar and Sjenica cheese have protected geographical indication on the national level. As Homolj, Zlatar and Sjenica cheese are raw milk cheeses produced in the traditional manner, LAB originating from the raw milk and the environment constitute an important part of Serbian traditional cheeses’ microbiota. There are many data in the scientific literature that LAB can carry transmissible antibiotic resistance genes. The aims of this doctoral dissertation were to: characterize biodiversity of traditional Serbian cheeses; determine phenotype and prevalence of antibiotic resistance; define genetic basis of tetracycline resistance in the LAB isolates and to investigate possibility for in vitro transmission of the tet genes. Total of 48 samples traditional Serbian cheeses (13 samples of Homolj cheese, 20 samples of Zlatar cheese and 15 samples of Sjenica cheese) were analyzed. All samples were plated on MRS-S agar plates in order to determine LAB count and on MRS-S agar plates with added tetracycline in doubling concentrations (1-256 μg/ml), in order to determine tetracycline resistant LAB subpopulation count. Average count of LAB in Homolj cheese was 7,65±1,09 log CFU/g, in Zlatar cheese 7,74±0,6 log CFU/g and in Sjenica cheese 7,47±0,71 log CFU/g. Addition of tetracycline in concentration of 64 μg/ml has considerably reduced LAB count, which was in Homolj cheese 3,98±2,28 log CFU/g, in Zlatar cheese 3,35±2,02 log CFU/g and in Sjenica cheese 3,93±2,24 log CFU/g...Lanac hrane predstavlja jedan od mogućih puteva transmisije bakterija rezistentnih na antibiotike između populacija životinja i ljudi. Komensalne bakterije, poreklom od životinja, predstavljaju deo mikrobiote hrane životinjskog porekla, i često se prepoznaju kao „rezervoari“ gena za rezistenciju na antibiotike. Rezistencija na tetraciklin kod komensalnih bakterija je dobro dokumentovana i s obzirom da je prenosive prirode, koristi se kao model za praćenje ekologije rezistencije na antibiotike. Homoljski, zlatarski i sjenički sir su na nacionalnom nivou zaštićeni oznakom geografskog porekla. Proizvode se na tradicionalan način, od sirovog mleka, te bakterije mlečne kiseline, poreklom iz sirovine i/ili procesnog okruženja čine značajan deo mikrobiote tradicionalnih sireva Srbije. U naučnoj literaturi postoje brojni podaci o tome da bakterije mlečne kiseline mogu biti nosioci gena za rezistenciju na antibiotike. Ciljevi ove doktorske disertacije bili su: karakterizacija biodiverziteta tradicionalnih sireva Srbije, utvrđivanje fenotipa i prevalencije rezistencije na antibiotike i genetske baze rezistencije na tetraciklin kod izolata bakterija mlečne kiseline poreklom iz tradicionalnih sireva, kao i mogućnosti prenosa tet gena u uslovima in vitro. Ukupno 48 uzoraka tradicionalnih sireva (13 uzoraka homoljskog sira, 20 zlatarskog i 15 uzoraka sjeničkog sira), zasejano je na MRS-S agar radi utvrđivanja broja BMK i na MRS-S agar sa dodatkom tetraciklina u dvostrukorastućim koncentracijama (1-256 μg/ml), kako bi se utvrdila zastupljenost populacije BMK rezistentne na tetraciklin. Prosečan broj BMK u uzorcima homoljskog sira iznosio je 7,65±1,09 log CFU/g, u uzorcima zlatarskog sira 7,74±0,6 log CFU/g i u uzorcima sjeničkog sira 7,47±0,71 log CFU/g. Pri koncentraciji tetraciklina od 64 μg/ml primećeno je veće smanjenje broja BMK..
Evaluation of Preeclampsia Risk in Gestational Weight Gain
Background: The incidence of obesity worldwide has increased over the last 20 years. The increase in obesity in maternal pregnancy is causing a major challenge to obstetrics practices. The aimed study was to evaluate gestational weight gain as a risk for preeclampsia in pregnant women. Methods: This cross-sectional study was conducted on 2756 pregnant women with gestational age≥37 weeks. The selection of women was categorized into two groups, 1528 normal-weight women with BMI less than 25kg/m2 and 1228 pregnant women with a BMI of 25kg/m2 or more. SPSS software version 26.0 was used to analyze data. Multivariate logistic regression described the relation of weight change to pregnancy course and outcomes. Results: A comparison between study groups shows an increase in antepartum complications in obese women. Besides that, arterial hypertension, pre-eclampsia, and gestational diabetes were more frequent in overweight women compared to normal-weight women. The incidence of cesarean was highest in overweight and obese women with a statistically significant difference from normal weight women (p-value <0.005). In addition, maternal overweight and obese were at twice the risk for delivering infants with macrosomia (OR = 3.1, 95%CI = [1.09-5.8]). The difference in mean birth weight of the babies between normal and overweight women was statistically significant (p<0.05). Conclusion: The results of this study show that obesity during pregnancy is associated with pregnancy complications. To optimize all complications for the mother and fetus, weight gain during the pregnancy must be controlled and appropriate. Furthermore, studies are recommended to explore maternal obesity complications and risk factors for obesity to minimize the adverse effect of this risk.

The incidence of cesarean was highest in obese women statistically significant difference from normal women with a p-value <0.005. In addition, maternal obese pregnancies were at twice the risk for delivery of infants who were macrosomia with higher odds (OR = 3.1, 95%CI = [1.09-5.8]). In perinatal outcomes, the difference in mean birth weight of the babies among normal and obese women was statistically significant (p<0.05). Conclusion: As we saw from the results of this study obesity during pregnancy was associated with pregnancy complications. To optimize all complications to maternal and fetus, weight gains during the pregnancy must be controlled and appropriate. Furthermore, studies are recommended to explore the maternal obesity complication and risk factors that influence obesity to minimize the adverse negative effect of this risk

Safety evaluation of Sjenica cheese with regard to coagulase-positive staphylococci and antibiotic resistance of lactic acid bacteria and staphylococci
Sjenica cheese is an artisanal cheese stored in brine, traditionally produced from raw sheeps milk in the southern part of Serbia - Sjenica Pester plateau. The aim of this study was to perform the safety evaluation of Sjenica cheese. As one of the safety criteria we considered the number of coagulase positive staphylococci and their enterotoxigenic potential. Antibiotic susceptibility/resistance patterns of autochthonous lactic acid bacteria and coagulase-positive staphylococci isolated from Sjenica cheese was also investigated. During the monitoring period of the cheese-making process, coagulase positive staphylococci did not reach the value of 10(5) cfu/g. Among coagulase positive staphylococci, 12 (46,15%) isolates showed enterotoxigenic potential and were identified as Staphylococcus intermedius (11 isolates) and Staphylococcus aureus (1 isolate). Vancomycin resistance was the most prevalent phenotypic resistance profile in coagulase positive staphylococci. Lactococci present the most dominant population among lactic acid bacteria. The most prevalent resistance phenotype in lactococci was resistance to streptomycin (83.33%), ampicillin and penicillin (70.83%); lactobacilli were characterized by resistance to vancomycin (62.5%) and tetracycline (54.17%), while resistance to streptomycin (82.46%) was the most prevalent phenotypic profile in enterococci. All coagulase positive staphylococci and lactic acid bacteria isolates that showed resistance to tetracycline on disc diffusion and E-test, were tested for the presence of ribosomal protection proteins, tet(M) and tet(K) genes. All isolates were positive for ribosomal protection proteins genes; 14 (60.87%) isolates showed tet(M) gene presence, while 2 lactobacilli isolates revealed the presence of tet(K) gene
