    Opis:
    Introduction. Marijuana is one of the most widely used psychoactive substance. There is evidence of genetic predisposition for addiction. Objective. The aim of the study is to evaluate personality traits measured by the NEO Five-Factor Inventory and State-Trait Anxiety Inventory, combined with analysis of Tag1B rs1079597 and Tag1D rs1800498 located in the DRD2 gene. Materials and method. The study group consisted of 214 rural cannabinoid users and 301 controls. The same psychometric test and real-time PCR genotyping were performed in both studied groups. Results. The values of Anxiety state, Anxiety trait, NEO FFI: Neuroticism and Openness in the rural cannabis using group were significantly higher than in the control group. On the other hand, lower values were observed among rural people using cannabis compared to the control group for NEO FFI: Extraversion, Agreeability and Conscientiousness. In the Anxiety trait subscale, a 2% association with the polymorphism DRD2 Tag1B rs1079597 was detected in subjects using cannabis. However, for the DRD2 Tag1D rs1800498, there was no effect on the differences in personality traits between rural cannabis users and the control group. Conclusions. The study shows differences in personality traits between the cannabis using group and controls. Interaction between genetic factors and personality traits was also detected. The association showing the combination of psychological characteristics and genetic variants can bring us closer to the overall picture of the issue of marijuana addiction.

    Opis:
    Introduction. Substance abuse significantly influences human health and may induce problems with social functioning worldwide. Numerous genetic and environmental risk factors, as well as their interactions, accelerate the development of drug addiction. Etiologically, the dopaminergic mesocorticolimbic reward pathways are related to psychoactive substance addiction, and the reward properties of heroin are connected with changes in the mesolimbic dopaminergic system. Objective. The aim of this study is a haplotypic analysis of subjects addicted to polysubstance. However, with the knowledge that this is not a homogenous subgroup, it was decided to separate and analyze homogenous subgroups of subjects in order to find specific haplotypic variants among them. The subjects in the subgroups were addicted to heroin, and subjects with more than two relapses in the past two years. Materials and method. The study group comprised of 301 polysubstance addicted rural male subjects. From this group, 2 homogenous subgroups of subjects were isolated and additionally analyzed: (1) a group of heroin addicted subjects (n=61), and (2) a group of heroin-addicted subjects with at least two relapses in the last two years (n=21). The group consisting of all polysubstance addicted rural subjects and both homogenous subgroups were analyzed against a control group of non-addicted subjects (n=300), matching gender and age. Five polymorphisms in the DRD2/ANKK1 region were analyzed: rs1076560, rs1800498, rs1079597, rs6276 in the DRD2 gene, and rs1800497 in the ANKK1 gene. Results. A statistically significant haplotype association was found in analysis of the heroin addicted subjects, compared to controls, and two possible trends – when comparing the whole group of addicted subjects to controls, and in relapse subgroups, compared to the controls. Conclusion. The results obtained showed that haplotypes indicate a part of the biological component of addiction.

    Opis:
    Objective. The aim of the study was to assess the impact of a fattening season on the level of airborne chemical and microbial pollutants in the pig fattening house. Materials and method. Evaluation of the air composition as well as the microbiological air quality were made during 2 series, i.e. in the summer and winter period of fattening. Airborne gaseous pollutants were analyzed by gas (organic compounds) and liquid (inorganic compounds) chromatography methods. Air microbial contamination was determined in compliance with the Polish Standard PN-EN 13098:2007. Results. The air/gas composition in the pig unit showed that irrespective of the fattening season, the level of determined pollutants – especially ammonia, volatile organic compounds (VOCs), including methanethiol and total dust – could have an adverse effect on the health of swine facility workers. The investigated pig building was found to be a source of chemical pollutants as well as biological agents. The total bacterial count in 1 m3 of air was 3.6×106 and 4.6×106 cfu, during the winter and summer periods of fattening, respectively. Gram-positive cocci predominated in both seasons. In the winter, fungi of the Trichoderma genus were represented equally often. In the summer period, up to 90% of the isolated fungus was Aspergillus spp. Conclusions. Workers engaged in swine rearing and production are occupationally exposed not only to a high concentration of microbial contamination, but also to irritating and odorogenous volatile compounds. Thus, activities directed at the promotion of health prevention strategies, as well as effective guidelines for safe and hygienic animal housing, should be implemented.

    Opis:
    Opisany jest projekt kontrolera komunikatów języka SCPI (ang. Standard Commands for Programmable Instruments) w postaci modułu przeznaczonego do sterowania działaniem precyzyjnego licznika czasu i częstotliwości. Moduł kontrolera został zintegrowany wspólnie z modułem pomiarowym licznika w pojedynczym układzie programowalnym XC3S400 firmy Xilinx. Do najważniejszych zadań kontrolera należy tłumaczenie komend tekstowych, przychodzących z komputera do licznika, z języka SCPI, na niestandardowe reprezentacje wewnętrzne oraz wykonywanie operacji odwrotnej celem interpretacji odpowiedzi.
    In the paper there is presented a design of the SCPI (Standard Commands for Programmable Instruments) controller as a module for control of the operation of a precise time and frequency counter developed at the Military University of Technology. Both modules (the controller and the time counter), that operate as a heart of a measuring device, were integrated in the same programmable chip (XC3S400, Xilinx). The main task of the controller translation of text messages from the SCPI language into corresponding non-standard representation of the commands executed by the counter. There is shown the block diagram of the SCPI controller and the structure of the proposed trees of SCPI commands. The presented technical solutions are based on the IEEE 488.2 standard as well as the SCPI specification. Our controller works with the dedicated set of commands occurring in the SCPI tree structure of the counter. This project can be relatively easy adapted to control other devices implemented in FPGA circuits. In this aspect, our solution can be used as a core of the intellectual property library. The principle of operation of the SCPI controller is based on a PicoBlaze microcontroller. The advantage of the proposed solution is low amount of occupied logic resources, whereas its drawback is the need to prepare a program for the processor in not friendly assembler language environment. An example of the program and the results of implementation and practical verification are also presented.
