Nový přístup k rozvrhování přidělování kolejí s nástupištní hranou vlakům

The aim of the paper is to introduce a decision-making tool for assignment of trains to platforms. Train platforming problem is formulated as special case of parallel machine scheduling problem in which jobs and parallel machines are synonymous with trains and tracks. Objectives of the model are to minimize total delay of trains and to maximize number of trains (station capacity) and to maximize number of connecting trains assigned to the same platform.Cílem článku je přestavit rozhodovací nástroj pro přidělování kolejí s nástupištní hranou jednotlivým vlakům. Problém přidělování kolejí je formulován jako speciální případ úlohy rozvrhování práce paralelních strojů, kdy úlohy a stroje jsou synonymy pro vlaky a koleje. Kritérii modelu jsou minimalizace součtu zpoždění vlaků a maximalizace počtu odbavených vlaků (propustnosti stanice) stejně, jako maximalizace počtu případů dvojic vlaků (považovaných za přípojné), jimž je přiděleno stejné nástupiště (přestup typu hrana-hrana)

Tendency towards violence and social roles: a descriptive study among high school students in Turkey

Background: Violence affects more than half of women worldwide and the perception of social roles has a significant role in this. Adolescence is a sensitive developmental period in the life of an individual. It is therefore important to understand the perception of violence and change the acceptance of violence among adolescents

Health literacy levels of the workers in a steel factory: A cross sectional study in Turkey

© 2018 Faculty of Health and Social Sciences of University of South Bohemia in České BudějoviceHealth literacy is important as it shows the degree to which a person understands and interprets medical information and makes the appropriate health decision. The workers of steel factories are often faced with health information and issues in their work place related to personal protection, occupational hazards and occupational injuries. Therefore, it is important to demonstrate the health literacy of the workers to ensure health literacy responsive work places. This paper aims to show the health literacy level of the steel factory male workers in Turkey. In this study, in order to measure the health literacy level of men, REALM and NVS scales were used. Additionally, questions related to socio-demographics and the health information sources and General Health Questionnaire were applied. For the analysis, chi-square and ANOVA tests were used. Of the participants, the mean age was 34.9 ± 8.8 (min.–max. = 18–53), the mean scores were 64.0 ± 2.1, 3.2 ± 1.2, and 1.5 ± 0.8, respectively for REALM, NVS and GHQ scales. According to REALM scale, 8.1% (n = 20) of the workers had limited health literacy. Whereas, in the NVS scale, 5.7% (n = 14) had inadequate health literacy, and 55.1 % (n = 136) had limited health literacy. At least one of every ten workers had limited or inadequate health literacy level. The results should be taken into consideration by the healthcare providers and policymakers while implementing health promotion interventions to increase the health literacy level of the workers

Health professionals exposure to mobbing in a medical school hospital

Aim: This study was conducted to reveal the perceptions of the residents and nurses working in their workplace. Material and Methods: This study is a cross-sectional descriptive study. the study was carried out between October 2014 and January 2016. the study population consisted of the residents and nurses working in Manisa Celal Bayar University, Hafsa Sultan Hospital. the study sample included 110 people. the survey was performed using a questionnaire consisting of an Information Form and the Work Harassment Scale. Results: the employees’ mean age was 29.92±5.47; 73.6% of them were female and 59.1% married; 46.4% had bachelor’s degree; 61.8% had balanced income and expenses; 32.7% were residents and 60.9% nurses/midwives; and 26.4% were victims of mobbing. Some 13.6% of those who were subject to mobbing stated that they were exposed to mobbing for 6 to 11 months. Approximately 42.7% of the health professionals stated that they witnessed others being subject to mobbing. Some 24.5% of the health professionals expressed their need for psychological support. Conclusion: the study showed that those with high level of education, those in the younger adult group (22-30 years of age) and those who needed psychological support were at a higher risk of being exposed to mobbing, the difference being statistically significant (p<0.05). To reduce the level of mobbing and provide quality healthcare services in hospitals, arrangements should be made to increase the number of nurses/midwives and doctors at work, and to educate employees on subjects related to communication and mobbing by psychiatric nurses

Genetic Polymorphism Of Manganese Superoxide Dismutase In Behcet'S Disease

Objectives: This study aims to investigate the genetic association between single nucleotide mutation in mitochondrial manganese superoxide dismutase and a Behcet's disease (BD) population by using molecular techniques. Patients and methods: Ninety-three BD patients (45 males, 48 females; mean age 33.15 +/- 8.99 years; range 17 to 65 years) and 125 controls (58 males, 67 females; mean age 28.33 +/- 7.31 years; range 18 to 62 years) were genotyped by polymerase chain reaction-restriction fragment length polymorphism method. The genotypic distributions in BD patients and controls were consistent with the Hardy-Weinberg equilibrium. Results: Significant differences were observed between BD patients and controls in terms of genotypic distribution. Frequencies of alanine (Ala)/Ala, Ala/valine (Val), and Val/Val were 14.0% (n=13), 45.2% (n=42), and 40.9% (n=38) in BD patients and 21.6% (n=27), 53.6% (n=67), and 24.8% (n=31) in controls, respectively (p=0.033). Conclusion: The Val/Val genotype of the manganese superoxide dismutase gene is associated with the physiopathology of BD in a group of Turkish patients.Wo

Microbial monitoring of ammonia removal in a UASB reactor treating pre-digested chicken manure with anaerobic granular inoculum

Performance and microbial community dynamics in an upflow anaerobic sludge bed (UASB) reactor coupled with anaerobic ammonium oxidizing (Anammox) treating diluted chicken manure digestate (Total ammonia nitrogen; TAN = 123 +/- 10 mg/L) were investigated for a 120-d operating period in the presence of anaerobic granular inoculum. Maximum TAN removal efficiency reached to above 80% with as low as 20 mg/L TAN concentrations in the effluent. Moreover, total COD (tCOD) with 807 +/- 215 mg/L in the influent was removed by 60-80%. High-throughput sequencing revealed that Proteobacteria, Actinobacteria, and Firmicutes were dominant phyla followed by Euryarchaeota and Bacteroidetes. The relative abundance of Planctomycetes significantly increased from 4% to 8-9% during the late days of the operation with decreased tCOD concentration, which indicated a more optimum condition to favor ammonia removal through anammox route. There was also significant association between the hzsA gene and ammonia removal in the UASB reactor. (C) 2017 Elsevier Ltd. All rights reserved
