    Full Text Available The article deals with the study of British-German relations during the period of exacerbation of territorial disputes between Germany and Poland in 1929-1931. Germany was making plans for revising the eastern borders. It sought to enlist the support of the new Labour government. Britain didn’t only approve of Germany's intention to carry out revision of the Treaty of Versailles (reparation issue, the evacuation of the Rhineland and the change in the German-Polish border, but also supported the strengthening of the political and economic situation in Germany as a whole. Assistance to Germany was advantageous for Britain. Firstly, the British support helped to improve the capacity of the purchasing power of the German market as one of the traditional markets of the English sale. Secondly, the strengthening of the position of the German cabinet meant failure of the French policy in Europe at this stage. The defeat of France in a dispute on the issue of early evacuation of the Rhineland would seriously devalue the foreign policy initiatives of Paris. Thirdly, the British government hoped that Germany will go into orbit of British political influence. The identity of the positions of the German and the British cabinets were considered as the components of British policy success not only in relations with France and Italy, but also with Czechoslovakia and Poland. Since the formation of the MacDonald’s cabinet, anti-Polish moods increased in the British course for the settlement of German-Polish relations. However, the threat of an attack on Poland by Germany was regarded by the government of Britain as unacceptable way of resolving the German-Polish conflict. Britain tried to follow the traditional foreign policy concept of “balance of power”, but the inefficiency of British policy “mediation” in European affairs was clearly shown in times of growing financial and economic crisis. The issue of the German-Polish border remained unsolved.

    Dołzbłasz Sylwia


    Full Text Available The symmetry and/or asymmetry in terms of cross-border openness of service providers is examined in this article, for the cases of two border twin towns: Cieszyn/Český Těšín at the Polish-Czech border, and Gubin/Guben at the Polish-German border. To assess the level of openness of firms towards clients from the other side of the border, four trans-border categories were examined: neighbour’s language visible at store location; business offers in the language of the neighbour; the possibilities of payment in the neighbour’s currency; and the staff’s knowledge of the language. This enabled a comparison of both parts of the particular twin towns in relation to the character of cross-border openness, as well as an assessment of their symmetry/asymmetry. Comparisons of Gubin/Guben and Cieszyn/Český Těšín with respect to the analysed features were also carried out. The analysis shows significant variation in the level of cross-border openness towards clients from neighbouring countries. Whereas in the Polish-Czech town a relative symmetry was observed, in the Polish-German case, significant asymmetry was noted.

    Full Text Available The effects of World War II influenced the relations between the nations of Europe. They also influenced the life of the Church in a universal way, because its members found themselves of both sides of the Iron Curtain. This was particularly visible in Polish-German relations. The Polish bishops, inspired by the message of the Gospel and the legacy of the Second Vatican Council, came forward with a proposal of initiating the process of reconciliation. The words, “we forgive and ask for forgiveness”, contained in the Letter to the German Bishops of 1965, became the inspiration for the years-long reconciliation effort. The specific results of this formula are indicated in the formal normalisation of the state and church relations. In the ecclesial dimension, it included a new canonical diocese order and cooperation on the pastoral, charitable and journalistic plane. The real influence of the Polish-German reconciliation on the process of integration of the peoples of Europe should be emphasised. In this sense, the influence of the Christian message on shaping the public sphere is revealed.

  5. South German Inspirations in the Armour of Late Medieval Combatants from the Silesian-Lusatian-Brandenburg-Polish Borderland. Iconographic Examples


    Michalak, Arkadiusz


    There are visible tendencies in the late medieval iconography from the Silesian-Lusatian-Brandenburg-Polish borderland, indicating strong South German inspiration in depicted armour. The presence of this kind of protection on works of art from this region can most likely be connected with political, family and artistic reasons.

    Full Text Available The aim of the paper was to present the differences in the level and structure of utilisation of services in Polish and German agriculture. An attempt to define the factors influencing these values was also done. The research covered the share of agricultural services, veterinary expenses and financial intermediation services in intermediate consumption, the value of the studied services per 1 hectare of agricultural land, 1 AWU or 1 DJP, as well as services absorptivity of agricultural production. It was proved that although a significant difference between the role of these services in Poland and Germany still exists, in many cases in 2012 it was not so considerable as in 1998. It can be also assumed that further absorption of funds from the European Union will stimulate investment processes in Polish agriculture, and progressive improvement in utilisation of services by Polish agriculture.

  9. Occurrence of hypercementosis in a German population. (United States)

    Bürklein, Sebastian; Jansen, Sabine; Schäfer, Edgar


    The purpose of this study was to assess the occurrence of hypercementosis in a selected German dental school patient population. A total of 800 full-mouth periapical radiographic series were screened. The radiographs were evaluated under optimal conditions by using double magnifying glasses. A total of 18,589 teeth including third molars were evaluated. The relative incidence of hypercementosis and the correlation regarding the location (left-side versus right-side occurrence, maxillary versus mandibular, and anterior versus posterior teeth) and between men and women were recorded and analyzed by using the χ(2) test. Eleven patients were found to have hypercementosis, 10 women and 1 man (P hypercementosis, and 6 had more than 1 (54.54%). In total, 22 teeth associated with hypercementosis were found. Seven maxillary teeth were associated with hypercementosis (31.82%) and 15 mandibular teeth (68.18%) (P = .198). No significant differences were found regarding left-side and right-side occurrence of the affected teeth (P > .05). Hypercementosis was significantly more often associated with premolars and molars than with incisors (P Hypercementosis was found in 11 of 800 patients (1.33%). It was identified in 22 of the 18,589 teeth examined (0.12%). The occurrence of hypercementosis among this selected German population was rare. Female patients were approximately 10 times more often affected than male patients. Mandibular teeth were approximately twice as often associated with hypercementosis as maxillary teeth.

  10. The level of health education in the Polish population. (United States)

    Olszanecka-Glinianowicz, Magdalena; Chudek, Jerzy


    The study assessed factors influencing awareness of Poles concerning lifestyle factors that affect development of obesity, type 2 diabetes and cardiovascular diseases (CVD). A questionnaire survey covering awareness of lifestyle factors performed by general practitioners in 37,557 unselected patients. 96.1% of respondents believed that lifestyle has an impact on the occurrence of CVDs, especially: tobacco smoking (91.4%), excessive intake of fat (81.3%), alcohol (67.5%), salt (64.9%), and stress (64.9%). 79.0% respondents believed the smoking cessation, 77.5% weight loss and 66.8% healthy diet are most important to prevent diseases. Additionally, the belief in the need for an early weight reduction decreased with increasing BMI (82.9% with normal weight vs. 77.5% overweight and 70.4% obese). The most common source of health education was a physician (75.8%), the mass media, such as television and the press (62.0% and 64.8%, respectively), less often were educational materials (37.8%) and books (20.3 %), the Internet (3.8%) and radio (0.8%). Younger respondents presented a higher level of awareness about all analysed aspects of healthy lifestyle. The multiple regression analysis revealed that low education level and rural residence are the most important factors decreasing awareness of the lifestyle effect on health. 1. The level of knowledge about non-pharmacological methods of preventing lifestyle diseases in the Polish population is high except of the role of physical activity and daily vegetables consumption. This, however, has no impact on reducing the percentage of overweight and obese people and on increasing the tendency to pursue lifestyle changes. 2. Frustrating is the fact that more than one fifth of the study population is unaware that excessive weight reduction prevents development of cardiovascular diseases. Moreover, the convince to early weight decreases with increasing BMI. 3. The highest level of the knowledge among younger subjects reflect

    Zdrojewski, Łukasz; Król, Ewa; Rutkowski, Bolesław; Piotrowski, Walerian; Pająk, Andrzej; Drygas, Wojciech; Zdrojewski, Tomasz


    Kidney filtration decreases with age, which results in an increased frequency of chronic kidney disease (CKD) in the elderly population. The purpose of the study was to assess the prevalence and epidemiology of CKD in the Polish elderly population. A representative sample of the Polish elderly population, composed of 918 people (F 452, M 466) in the age of ≥75 years, was chosen. All participants had their history, anthropometric measures and biochemical parameters (creatinine, fasting glucose, complete cholesterol) evaluated. CKD was diagnosed when eGFR was elderly population was 26.9%. 2. Awareness of CKD is low. 3. DM, increasing age and AH did not increase the risk of CKD. 4. Coexistence of cardiovascular diseases increased the risk of having CKD.

  14. Estimation of dietary intake and patterns of polyphenol consumption in Polish adult population. (United States)

    Zujko, M E; Witkowska, A M; Waśkiewicz, A; Sygnowska, E


    Polyphenols play an important role in the prevention of degenerative diseases, particularly cardiovascular diseases and cancers. The purpose was to estimate dietary polyphenol intake in Polish adults, using own database of food polyphenols, and to establish main dietary sources of polyphenols. Polish men and women (6661) aged 20-74 years were randomly selected from the Polish National Multicenter Health Survey (WOBASZ). Subjects` daily food consumption was estimated by the 24-hour recall method and was continued for 3 years. It was determined on this basis, that 96 plant foods and plant food products were consumed. The own dietary database of polyphenol contents in food was used to calculate polyphenol intakes in the subjects. The daily total polyphenol intakes were calculated for both genders in individual age categories: 20-40 years, 41-60 years and 61-74 years. The average polyphenol consumption for the men was 1172 mg/day, and for the women it made 1031 mg/day. Plant food categories such as beverages, vegetables, fruits and cereals were found to be significant sources of polyphenols, of which tea, coffee, potatoes, apples and white bread were the main contributors. The amount of polyphenol consumption in Polish adult population is similar to the polyphenol intake in other countries populations, accounting roughly for 1g of polyphenols for both genders and different age groups. Patterns of polyphenol consumption, however, vary for genders and age groups. Polyphenols are characterized by a spectrum of antioxidant capabilities, therefore future studies should focus on dietary intakes of individual polyphenols.

  16. Challenges in inbreeding estimation of large populations based on Polish Holstein-Friesian cattle pedigree. (United States)

    Sell-Kubiak, Ewa; Czarniecki, Łukasz; Strabel, Tomasz


    The aim of this study was to evaluate observed and future inbreeding level in Polish Holstein-Friesian cattle population. In total, over 9.8 mln animals were used in the analysis coming from the pedigree of Polish Federation of Cattle Breeders and Dairy Farmers. Inbreeding level, as an average per birth year, was estimated with the method accounting for missing parent information with the assumption of year 1950 as the base year of the population. If an animal had no ancestral records, an average inbreeding level from its birth year was assigned. Twice the average inbreeding level served as relatedness of the animal to the population, which enabled estimation of inbreeding in its offspring. The future inbreeding of potential offspring was estimated as an average of animals (bulls and cows) available for mating in a certain year. It was observed that 30-50% of animals born between 1985 and 2015 had no relevant ancestral information, which is caused by a high number of new animals and/or entire farms entering the national milk recordings. For the year 2015, the observed inbreeding level was 3.30%, which was more than twice the inbreeding with the classical approach (without missing parent information) and higher by 0.4% than the future inbreeding. The average increase of inbreeding in years 2010-2015 was 0.10%, which is similar to other countries monitored by World Holstein-Friesian Federation. However, the values might be underestimated due to low pedigree completeness. The estimates of future inbreeding suggested that observed inbreeding could be even lower and also increase slower, which indicates a constant need to monitor rate of increase in inbreeding over time. The most important aspect of presented results is the necessity to advise individual farmers to keep precise recordings of the matings on their farm in order to improve the pedigree completeness of Polish Holstein-Friesian and to use suitable mating programs to avoid too rapid growth of inbreeding.

  17. The Incidence of Hypogonadotropic Hypogonadism in Type 2 Diabetic Men in Polish Population (United States)

    Rabijewski, Michał; Zgliczyński, Wojciech; Piątkiewicz, Paweł


    The aim of this study was to investigate the incidence of hypogonadotropic hypogonadism (HH) in type 2 diabetic men (T2DM) in population of Polish men and examine the possible influence of estradiol levels and glycemic control. We evaluated TT, cfT, estradiol, and glycemic control (HbA1c) in 184 diabetic men and in 149 nondiabetic control group. The mean HbA1c was 8.6 ± 0.2% and 6.1 ± 0.3% and cfT concentration was 0.315 ± 0.08 nmol/L and 0.382 ± 0.07 nmol/L, respectively. T2DM had higher E2 concentration than nonobese control men (29.4 ± 3.7 pg/mL versus 24.5 ± 2.9 pg/mL). Forty-six percent of T2DM were hypogonadal and 93% had HH. We observed inverse relationship between BMI and cfT (r = −0.341, P hypogonadism. High incidence of hypogonadotropic hypogonadism in type 2 diabetic men in Polish population is associated with poor glycemic control and can be secondary to an increase in estradiol concentrations.

    Full Text Available Prolactin receptor gene was found in pig chromosome 16, and it is one of the genes with a significant effect on reproduction traits in sows. The objective of the research was to determine polymorphism of the prolactin receptor gene in pigs of two maternal breeds: Polish Landrace and Polish Large White, as well as analyse relations between particular allelomorphic variants, and reproduction traits of examined sows. Two PRLR gene alleles, A and B, were isolated, they were obtained after AluI restriction gene digestion of the PCR product with the length of 163 bp; furthermore, three genotypes were identified: PRLRAA – 85, 59, 19 bp; PRLRAB – 104, 85, 59, 19 bp; PRLRBB – 104, 59 bp. We assessed 122 sows, in terms of their age at the first farrowing, as well as the sizes of the two subsequent litters. No statistically significant differences were found in the examined reproduction traits in sows with different allelomorphic relations, both within each breed and between breeds. Obtained results indicate that it is necessary to conduct further research on a larger animal group.

  19. Staphylococcus aureus from the German general population is highly diverse. (United States)

    Becker, Karsten; Schaumburg, Frieder; Fegeler, Christian; Friedrich, Alexander W; Köck, Robin


    This prospective cohort study evaluates colonization dynamics and molecular characteristics of methicillin-susceptible and - resistant Staphylococcus aureus (MSSA/MRSA) in a German general population. Nasal swabs of 1878 non-hospitalized adults were screened for S. aureus. Participants were screened thrice in intervals of 6-8 months. Isolates were characterized by spa and agr typing, mecA and mecC possession, respectively, and PCRs targeting virulence factors. 40.9% of all participants carried S. aureus at least once while 0.7% of the participants carried MRSA (mainly spa t011). MSSA isolates (n=1359) were associated with 331 different spa types; t084 (7.7%), t091 (6.1%) and t012 (71, 5.2%) were predominant. Of 206 participants carrying S. aureus at all three sampling time points, 14.1% carried the same spa type continuously; 5.3% carried different spa types with similar repeat patterns, but 80.6% carried S. aureus with unrelated spa types. MSSA isolates frequently harboured genes encoding enterotoxins (sec: 16.6%, seg: 63.1%, sei: 64.5%) and toxic shock syndrome toxin (tst: 17.5%), but rarely Panton-Valentine leukocidin (lukS-PV/lukF-PV: 0.2%). MSSA colonizing human nares in the community are clonally highly diverse. Among those constantly carrying S. aureus, clonal lineages changed over time. The proportion of persistent S. aureus carriers was lower than reported elsewhere. Copyright © 2016 Elsevier GmbH. All rights reserved.

  20. Trends in mortality and biological stress in a medieval polish urban population. (United States)

    Betsinger, Tracy K; DeWitte, Sharon


    Urbanization in pre-modern populations may have had a variety of consequences related to population crowding. However, research on the effects of urbanization have provided inconsistent results regarding the biological impact of this transition on human populations. The purpose of this study is to test the hypothesis that urbanization caused an increase in overall biological stress in a medieval (10th-13th centuries AD) Polish population. A human skeletal sample (n=164) was examined for the presence of porotic hyperostosis, cribra orbitalia, linear enamel hypoplasia, periosteal reaction, and specific infectious diseases. Prevalence rates were compared among three temporal samples: initial urbanization, early urbanization, and later urbanization. Results indicate no significant trends for any of the pathological conditions. Cox proportional hazards analyses, however, revealed a significant increase in the risk of death over time, which supports the hypothesis. These results reflect the necessity of using multiple analyses to address bioarchaeological questions. The lack of significant results from skeletal indicators may be due to an earlier urbanization trend in the population. This study illustrates that the association of urbanization with elevated biological stress is complicated and dependent on various factors, including culture and time period.

  1. Family studies of somatic and functional characteristics in the polish rural population

    Directory of Open Access Journals (Sweden)

    T Wieczorek


    Full Text Available In the present investigation we were trying to determine the genetic and environmental conditioning of the chosen somatic and functional traits in Polish rural population during ontogenesis. In order to find out interactions between environmental and genetic conditions of the studied traits, classical methods of quantitative features were applied: correlation coefficients corrected by assortative mating in the chosen types of heritability were evaluated on their base, heritability coefficients of analyzed features were assessed. The biggest stability of the correlation coefficients was observed for the length-parameters. We did not noticed stronger genetic control of functional features in men. Mean-strong genetic control among analyzed traits was observed in: reaction time, space orientation and static strength expressed as relative and absolute strength.

  2. Socioeconomic factors and the risk of metabolic syndrome in the adult Polish population: the WOBASZ study. (United States)

    Sygnowska, Elżbieta; Piwońska, Aleksandra; Waśkiewicz, Anna; Broda, Grażyna


    Metabolic syndrome (MetS) increases the risk of cardiovascular disease and its development is determined by certain socioeconomic and lifestyle factors. To investigate the impact of socioeconomic and lifestyle factors on the risk of MetS and the underlying contributing factors in the Polish population aged 20-74 years. Between 2003 and 2005, as part of the National Multicentre Health Survey (WOBASZ, Wieloośrodkowe Badanie Stanu Zdrowia Ludności), a random sample of Polish residents aged 20 to 74 years was investigated. Data on sociodemographic and anthropometric parameters, blood pressure, lipid and glucose levels and medical history were collected. MetS was defined according to the criteria proposed by the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI) and by the International Diabetes Federation (IDF) in 2005. Data necessary to evaluate MetS and the socioeconomic characteristics were obtained for 5940 men and 6627 women. MetS was identified in 26.0% of men and 23.9% of women according to the AHA/NHLBI definition, and in 30.7% of men and 26.8% of women according to the IDF definition. In both genders older age, higher body mass index and current smoking increased the risk of developing MetS, whereas higher physical activity and good self-rated health decreased the risk. Moreover, women with higher education and in the higher quartile of alcohol intake were associated with a lower risk of having MetS. Household per-capita income did not affect the risk of having MetS in either gender. A relatively high percentage of individuals with MetS was observed in the Polish population aged 20 to 74 years. In both sexes, the risk of MetS and its contributing factors was significantly associated with age and the following lifestyle factors: body mass index, smoking, self-rated health and, additionally for women, higher education and alcohol intake.

We observed inverse relationship between BMI and cfT (r=-0.341, P<0.01 and positive between BMI and E2 (r=0.329, P<0.01. E2 concentration was higher in T2DM with HH versus T2DM with normal TT/cfT concentration (34.5 ± 5.2 versus 27.4 ± 3.4 pg/mL. We observed negative correlation between HbA1c and cfT (r=-0.336, P<0.005 but positive between HbA1c and E2 levels (r=0.337, P<0.002. The prevalence of obesity, hypertension, and CVD was higher in men with hypogonadism. High incidence of hypogonadotropic hypogonadism in type 2 diabetic men in Polish population is associated with poor glycemic control and can be secondary to an increase in estradiol concentrations.

  4. Comparison of Various Databases for Estimation of Dietary Polyphenol Intake in the Population of Polish Adults (United States)

    Witkowska, Anna M.; Zujko, Małgorzata E.; Waśkiewicz, Anna; Terlikowska, Katarzyna M.; Piotrowski, Walerian


    The primary aim of the study was to estimate the consumption of polyphenols in a population of 6661 subjects aged between 20 and 74 years representing a cross-section of the Polish society, and the second objective was to compare the intakes of flavonoids calculated on the basis of the two commonly used databases. Daily food consumption data were collected in 2003–2005 using a single 24-hour dietary recall. Intake of total polyphenols was estimated using an online Phenol-Explorer database, and flavonoid intake was determined using following data sources: the United States Department of Agriculture (USDA) database combined of flavonoid and isoflavone databases, and the Phenol-Explorer database. Total polyphenol intake, which was calculated with the Phenol-Explorer database, was 989 mg/day with the major contributions of phenolic acids 556 mg/day and flavonoids 403.5 mg/day. The flavonoid intake calculated on the basis of the USDA databases was 525 mg/day. This study found that tea is the primary source of polyphenols and flavonoids for the studied population, including mainly flavanols, while coffee is the most important contributor of phenolic acids, mostly hydroxycinnamic acids. Our study also demonstrated that flavonoid intakes estimated according to various databases may substantially differ. Further work should be undertaken to expand polyphenol databases to better reflect their food contents. PMID:26569297

  6. Comparative population genetics of the German shepherd dog in South Africa

    Directory of Open Access Journals (Sweden)

    N. J. Coutts


    Full Text Available Modern breeding practices strive to achieve distinctive phenotypic uniformity in breeds of dogs, but these strategies are associated with the inevitable loss of genetic diversity. Thus, in parallel with the morphological variation displayed by breeds, purebred dogs commonly express genetic defects as a result of the inbreeding associated with artificial selection and the reduction of selection against disease phenotypes. Microsatellite marker analyses of 15 polymorphic canine loci were used to investigate measures of genetic diversity and population differentiation within and between German-bred and South African-bred German shepherd dogs. These data were quantified by comparison with typically outbred mongrel or crossbred dogs. Both the imported and locally-bred German shepherd dogs exhibited similar levels of genetic diversity. The breed is characterised by only a moderate loss of genetic diversity relative to outbred dogs, despite originating from a single founding sire and experiencing extensive levels of inbreeding throughout the history of the breed. Non-significant population differentiation between the ancestral German and derived South African populations indicates sufficient contemporary gene flow between these populations, suggesting that migration resulting from the importation of breeding stock has mitigated the effects of random genetic drift and a population bottleneck caused by the original founder event in South Africa. Significant differentiation between the combined German shepherd dog population and the outbred dogs illustrates the effects of selection and genetic drift on the breed since its establishment just over 100 years ago.

  7. Chinese pond mussel Sinanodonta woodiana (Lea, 1834 (Bivalvia: origin of the Polish population and GenBank data

    Directory of Open Access Journals (Sweden)

    Marianna Soroka


    Full Text Available DDNA sequences of the mitochondrial cox1 gene were analysed in 4 new local populations of Sinanodonta woodiana (Bivalvia in Poland, in the first reported Polish population, and in a population from Hungary. The gene sequences of Polish specimens were identical to those of specimens from Hungary, Italy and Ukraine, but different from those of Romanian specimens (data from GenBank. According to fish farm documentation, S. woodiana had spread in Poland by 2 routes: i direct import of fish infected by glochidia of S. woodiana from Hungary; and ii indirectly, by the major distributor of thermophilous fish in Poland, Gosławice Fish Farm, which started to import Hungarian fish in the 1960s. The genetic analysis and available documentation unambiguously confirm that Polish populations of S. woodiana derive from a source population in Hungary. In addition, we noticed doubtful identification of this species in GenBank data and further research is needed to resolve this problem.

    In recent decades, increases have been observed in the incidence of nonmelanoma skin cancers, including basal cell carcinoma (BCC) and squamous cell carcinoma. BCC is the most common neoplasm in Caucasian populations. Sonic hedgehog (Shh) pathway impairment plays a key role in BCC pathogenesis, and there is evidence that Shh pathway genetic variations may predispose to BCC development. We genotyped 22 single-nucleotide polymorphisms (SNPs) in 4 Shh pathway genes: SHH, GLI, SMO, and PTCH. The study group consisted of 142 BCC patients and 142 age-matched, sex-matched healthy subjects (controls). SNPs were assessed using the PCR-RFLP method. The genotype distribution for the polymorphisms in the rs104894049 331 A/T SHH, rs104894040 349 T/C SHH, and rs41303402 385 G/A SMO genes differed significantly between the BCC patients and the controls. The presence of CC genotype in the SHH rs104894040 349 T/C polymorphism was linked to the highest risk of BCC development (OR 87.9, p skin cancerogenesis. These results mainly underline the potential role of SHH3 rs104894040 349 T/C gene polymorphism in the development of skin basal cell carcinomas in patients of Polish origin.

    Accessory mental foramen (AMF) is a rare anatomical variation. When accessory mental foramen is present, the nerves and vessels that go through the mental foramen (MF) must follow alternative courses and special care must be taken during dental treatment planning. The purpose of this study was to evaluate the occurrence and the location of AMF in a selected Polish population using cone-beam computed tomography (CBCT). Two hundred CBCT (105 males and 95 females) examinations were evaluated for the presence of AMFs. The location and side of AMFs were reported. The mean distance between MF and AMF was also calculated. The vertical size of MF on the side with and without AMF was measured. The obtained variables were statistically analyzed. AMFs were observed in 7% of the patients. There was no statistically significant difference between the appearance of AMF and sex (p > 0.05). We found no significant difference in the vertical size of MF between individuals with and without AMFs (p < 0.05). Twenty-eight AMFs (7%) were observed from 400 sides of 200 patients. AMFs occurred more often in males (18 AMFs) than in females (10 AMFs). Twenty AMFs (71.4%) were located anteriorly, and eight (28.6%) - posteriorly. Fifteen AMFs (53.6%) were on the right side and thirteen (46.4%) - on the left.

  10. Serological and nested PCR survey to determine the occurrence of Chlamydia infections in the Polish cattle population. (United States)

    Szymańska-Czerwińska, Monika; Niemczuk, Krzysztof; Galińska, Elżbieta Monika


    Chlamydia spp. is an obligate intracellular agent that causes chlamydiosis in animals and humans. The aim of the presented study was to investigate the prevalence of Chlamydia infection in the Polish cattle population, both asymptomatic and having reproductive disorders. The study was performed on 4,475 serum samples collected from 16 Polish provinces at the turn of 2009-2011. The samples (3,419 from asymptomatic cattle and 1,056 from cattle with reproductive disorders) were tested by complement fixation test (CFT). Moreover, 160 and 201 samples of biological materials from both groups of cattle, respectively, were tested by nested PCR. The results obtained for two tested groups were compared by χ2 (ch-squared) test, both individually for each region (province), and generally for the whole country. The CFT results showed that the seroprevalence of Chlamydia spp. infections in the asymptomatic cattle population was 4.15%, while in the cattle with reproductive disorders--7.20%. There was a significant statistical difference between compared groups for whole country, but there were no significant differences for individual provinces. The results of PCR showed that Chlamydia spp. was present in both asymptomatic cattle and cattle having reproductive disorders. The nested PCR study confirmed the presence of Chlamydia abortus and Chlamydia suis in the tested samples. The presented study indicates that infections with Chlamydia spp. are present among Polish cattle, but the percentage of infected animals is not high.

  12. Assessment of substantia nigra echogenicity in German and Filipino populations using a portable ultrasound system. (United States)

    Go, Criscely L; Frenzel, Antonia; Rosales, Raymond L; Lee, Lillian V; Benecke, Reiner; Dressler, Dirk; Walter, Uwe


    Transcranial sonography of the substantia nigra for diagnosing premotor stages of Parkinson disease has been attracting increasing interest. Standard reference values defining an abnormal increased echogenic size (hyperechogenicity) of the substantia nigra have been established in several populations using high-end stationary ultrasound systems. It is unknown whether a portable ultrasound system can be appropriately used and how the Filipino population would compare with the well-studied white population. We prospectively studied substantia nigra echogenic sizes and third ventricle widths in 71 healthy adult German participants and 30 age- and sex-matched Filipino participants using both a well-established stationary ultrasound system (in the German cohort) and a recently distributed portable ultrasound system (in both ethnic cohorts). Mean substantia nigra echogenic sizes, cutoff values defining abnormal hyperechogenicity, and intra-rater reliability were similar with both systems and in both ethnic cohorts studied. The Filipino and German participants did not differ with respect to the frequency of insufficient insonation conditions (each 3%) and substantia nigra hyperechogenicity (10% versus 9%; P = .80). However, third ventricle widths were smaller in the Filipino than the German participants (mean ± SD, 1.6 ± 1.1 versus 2.4 ± 1.0 mm; P = .004). The frequency of substantia nigra hyperechogenicity appears to be homogeneous in white and Asian populations. Screening for this feature may well be performed with a present-day portable ultrasound system.

  13. Polish 2012 growth references for preschool children. (United States)

    Growth references are useful in monitoring a child's growth, which is an essential part of child care. The aim of this paper is to provide updated growth references for Polish preschool children and to assess how well children in Poland match or diverge from the World Health Organization (WHO) growth standards/references and recent German height-for-age references. The height-, weight-, body mass index-for-age, and weight-for-height references were constructed with the LMS method using data from a recent, large, population-representative sample of 4,941 preschool children aged 3 to 6 years (the OLA study). In the case of boys, the third, 50th, and 97th height percentiles of new Polish and German references overlap almost completely, whereas the WHO growth standards/references percentiles are systematically lower. In the case of girls, comparison between the new Polish and German height references showed conformity on the third and 50th percentile, whereas body height values of the WHO standards/references are shorter. Polish children aged 3 to 6 years from for the nation representative sample, had significantly greater than zero mean z scores of height-, weight-, and BMI-for-age and weight-for-height, relative to the WHO growth standards/references. The number of children in the sample with height-for-age below -2 SD was significantly lower than expected and number of children with height-for-age above +2 SD was significantly higher than expected. The OLA study growth references can be recommended as national references for preschool children in Poland.

    Full Text Available Austropotamobius torrentium (SCHRANK, 1803 is the smallest of the European native crayfish species and has probably never been of economic interest. It is confined to headwaters and adapted to cold water with high flow through and rocky environments. These properties make the stone crayfish a useful species for population genetics and phylogeographic studies. Representatives were collected from 18 localities throughout southern Germany and analysed with two mitochondrial genetic markers. Initial results revealed that German populations of A. torrentium from the Danube and Rhine tributaries share identical haplotypes in 528 basepairs of 16S rRNA and 658 basepairs of the COI gene. Rare haplotypes of the COI genes were occasionally encountered and apparently restricted to southwestern Bavaria. Only three variable sites were found over a length of 658 basepairs in 45 German, Swiss and Austrian stone crayfish resulting in five different haplotypes, with the prevalence of one most common haplotype. Here we show that in German populations rare haplotypes are not randomly distributed, but found in higher frequencies in the Bavarian Alps of the Allgäu and in adjacent Tyrol. On the other hand, stone crayfish population from the Bavarian Forest and the Rhine tributaries appear genetically impoverished, so far only showing the most common haplotype. Consequently, there are significant differences between the Allgäu populations and the rest of the German populations in haplotype frequencies, resulting in a relatively high FST value. This finding is of importance for future conservation efforts of stone crayfish populations in Germany and Austria.

  15. The “Polish question” in Soviet-German relations in the second half of the 1920s (based on the materials of the USSR consulate in Königsberg

    Directory of Open Access Journals (Sweden)

    Kostyashov Yuri


    Full Text Available On the basis of earlier unknown documents of the Soviet consulate in Königsberg retrieved from the Archive of the Foreign Policy of the Russian Federation, the author analyses relations between the USSR and Germany in 1925—1930. The author focuses on the role of the “Polish question”, which largely affected the nature of bilateral relations. The consulate documents indicate that Soviet diplomacy aspired to exploit the differences between Poland and Germany over a wide range of issues (the geopolitical situation of East Prussia, the position of national minorities, the problem of transit through the Polish corridor, the status of the Free city of Danzig, etc.. Soviet consuls carefully observed political life in Königsberg and the province. On the one hand, they paid attention to an increase in the nationalist and fascist attitudes. On the other hand, they emphasized the aspirations of the local political and business elite to develop economic cooperation with the Soviet Union. The People's Commissariat for Foreign Affairs tried to transform East Prussia into a Soviet lobby in the German government. These plans were not implemented at that time, but the 1920s ideas of cooperation between the two states on the anti-Polish basis were put into practice on the eve of World War II.

  16. Are dietary habits of the Polish population consistent with the recommendations for prevention of cardiovascular disease? - WOBASZ II project. (United States)

    Waśkiewicz, Anna; Szcześniewska, Danuta; Szostak-Węgierek, Dorota; Kwaśniewska, Magdalena; Pająk, Andrzej; Stepaniak, Urszula; Kozakiewicz, Krystyna; Tykarski, Andrzej; Zdrojewski, Tomasz; Zujko, Małgorzata E; Drygas, Wojciech


    Diet is a modifiable risk factor for cardiovascular disease (CVD). To assess diet quality in the adult Polish population, taking into consideration consumption of various nutrients as well as the total diet quality. Within the frame of the National Multicentre Health Survey (WOBASZ II), a random sample of the whole Polish population aged 20 years and above was screened during the years 2013-2014. Dietary habits were assessed in 5690 subjects (2554 men and 3136 women). Nutrient intakes were compared to the Dietary Reference Intakes. Total diet quality was measured using the Healthy Diet Indicator (HDI) score, based on the World Health Organisation recommendations for CVD prevention, that includes 7 nutrients (saturated and polyunsaturated fatty acids, cholesterol, protein, dietary fibre, fruits and vegetables, free sugars) and ranges from 0 (the least healthy diet) to 7 (the healthiest diet). The studied group was characterised by a high prevalence of overweight and obesity (69% in men vs. 59% in women), hypercholesterolaemia (56% vs. 55%, respectively), hypertension (50% vs. 42%), and diabetes (12% vs. 10%). At the same time, a significant percentage of Poles had improper dietary habits. A low fat and low cholesterol diet was reported by only 8% and a low calorie diet by 1% of the respondents. Adding salt to already seasoned dishes was reported by 27% of men and 18% of women, and 56% and 30% of them, respectively, consumed meat products with visible fat. The diet of most adult Polish citizens was found to be not balanced. Vitamins A, C, E, B1, B2, B6, and B12, protein, dietary cholesterol and fruits/vegetables were consumed in recommended doses only by 44-80% of the respondents. The recommended intake of fat, saturated and polyunsaturated fatty acids, which significantly affect lipid levels, was found in 18-37% of the respondents. Dietary intakes of folate and minerals important for the prevention of hypertension were insufficient. The desired level of folate

  17. Height loss with advancing age in a hospitalized population of Polish men and women: magnitude, pattern and associations with mortality

    Directory of Open Access Journals (Sweden)

    Chmielewski Piotr


    Full Text Available The connection between the rate of height loss in older people and their general health status has been well documented in the medical literature. Our study was aimed at furthering the characterization of this interrelationship in the context of health indices and mortality in a hospitalized population of Polish adults. Data were collated from a literature review and from a longitudinal study of aging carried out in the Polish population which followed 142 physically healthy inmates, including 68 men and 74 women, for at least 25 years from the age of 45 onwards. Moreover, cross-sectional data were available from 225 inmates, including 113 men and 112 women. These subjects were confined at the same hospital. ANOVA, t-test, and regression analysis were employed. The results indicate that the onset of height loss emerges in the fourth and five decade of life and there is a gradual acceleration of reduction of height at later stages of ontogeny in both sexes. Postmenopausal women experience a more rapid loss of height compared with men. The individuals who had higher rate of loss of height (≥3 cm/decade tend to be at greater risk of cardiovascular events and all-cause mortality. In conclusion, our findings suggest that a systematic assessment of the rate of loss of height can be useful for clinicians caring for elderly people because of its prognostic value in terms of morbidity and mortality.

    Directory of Open Access Journals (Sweden)

    Rosiak Joanna


    Full Text Available The present paper discusses the problem of dental anxiety. Based on the scientific review of Polish literature of the past 10 years, there are discussed causes of dental anxiety in different age groups and the methods of assessing the level of anxiety – physiological, behavioral, projection and psychological. Dental anxiety affects the patients’ attitude towards their own health, confidence in dentist, the frequency of reporting to the dental prophylaxis and treatment, which translates into oral health. It is also a major impediment to everyday clinical practice of a dentist.

  19. Wolfram syndrome in the Polish population: novel mutations and genotype-phenotype correlation. (United States)

    Zmyslowska, A; Borowiec, M; Antosik, K; Szalecki, M; Stefanski, A; Iwaniszewska, B; Jedrzejczyk, M; Pietrzak, I; Mlynarski, W


    Wolfram syndrome is a rare form of diabetes mellitus associated with optic atrophy and disorders of different organs (e.g. diabetes insipidus, hearing loss, ataxia, anaemia and many others). This syndrome is caused by recessive mutations in the wolframin gene (WFS1) localized on chromosome 4p16·1. The aim of this study was to identify the causative mutations in WFS1 in a group of Polish patients with suspected Wolfram syndrome. Nine patients with clinical symptoms consistent with Wolfram syndrome (at least diabetes mellitus and optic atrophy) and 22 first-degree relatives were examined. The molecular analysis was carried out by direct sequencing of the exons, the exon-intron junctions, and the 5' and 3' untranslated regions of WFS1. Nine different mutations in WFS1 (five of them novel) were identified in the nine patients. Six patients were homozygous for the following mutations: V412fs, S443R, W539X, V659fs. They developed diabetes at a mean age of 5·2 years. Three patients were compound-heterozygous for the following mutations: S167fs, Q392X, Y513fs, W648X, V779G. They developed diabetes at a mean age of 6·5 years. Mean age of diagnosis of diabetes among the Polish patients was typical for Wolfram syndrome; however, compound-heterozygous patients were slightly older at diabetes onset. © 2011 Blackwell Publishing Ltd.

  20. Chosen single nucleotide polymorphisms (SNPs) of enamel formation genes and dental caries in a population of Polish children. (United States)

    Gerreth, Karolina; Zaorska, Katarzyna; Zabel, Maciej; Borysewicz-Lewicka, Maria; Nowicki, Michał


    It is increasingly emphasized that the influence of a host's factors in the etiology of dental caries are of most interest, particularly those concerned with genetic aspect. The aim of the study was to analyze the genotype and allele frequencies of single nucleotide polymorphisms (SNPs) in AMELX, AMBN, TUFT1, TFIP11, MMP20 and KLK4 genes and to prove their association with dental caries occurrence in a population of Polish children. The study was performed in 96 children (48 individuals with caries - "cases" and 48 free of this disease - "controls"), aged 20-42 months, chosen out of 262 individuals who had dental examination performed and attended 4 day nurseries located in Poznań (Poland). From both groups oral swab was collected for molecular evaluation. Eleven selected SNPs markers were genotyped by Sanger sequencing. Genotype and allele frequencies were calculated and a standard χ2 analysis was used to test for deviation from Hardy-Weinberg equilibrium. The association of genetic variations with caries susceptibility or resistance was assessed by the Fisher's exact test and p ≤ 0.05 was considered statistically significant. Five markers were significantly associated with caries incidence in children in the study: rs17878486 in AMELX (p caries occurrence in Polish children.

    Full Text Available Recently, night eating syndrome (NES was included into the DSM-5 as an example of "Other Specified Feeding and Eating Disorders." The study provides insight into the population prevalence of NES using a large representative German population sample (n = 2,460 with a wide age range (14-85 years. The prevalence of NES was 1.1% using a cut-off on the Night Eating Questionnaire (NEQ of 25. A positive screening for NES was positively associated with depression and anxiety, eating disorder psychopathology, and body weight.

  2. Don't forget how severe varicella can be--complications of varicella in children in a defined Polish population. (United States)

    Gowin, Ewelina; Wysocki, Jacek; Michalak, Michał


    This study aimed to analyze the causes of hospitalization in children with varicella, based on a defined Polish population. This was a retrospective analysis of causes of hospitalization in children under 18 years of age with varicella, treated on the Infectious Diseases Ward of the Children's Hospital in Poznan, Poland from January 2007 to June 2012. The ward serves almost the entire child population of the Greater Poland region (10% of the Polish population - almost 600,000 children). The analysis was based on hospital records. Patients were identified using the International Classification of Diseases Tenth Revision (ICD-10) codes. The case definition consisted of physical evidence of varicella. A total of 224 children were hospitalized for varicella complications. The median age of admitted patients was 37.5 months (range 6 days to 17 years). Rates of hospitalization decreased with age. The highest rates were among children during their first year. Ninety-two percent of children were healthy prior to hospitalization (no chronic diseases). The most common complications were respiratory tract infections (26%), followed by skin infections (21%) and neurological symptoms (18%). Twenty-five patients (11%) had more than one complication. The most common coexisting conditions were dehydration and otitis media. The results presented here serve to remind us that varicella may to lead to severe complications in unvaccinated children and adolescents, and demonstrate the benefits of varicella vaccination. Most children hospitalized with varicella were immunologically healthy. Meningitis was more common in older children (>6 years of age). Streptococcus pyogenes was the most commonly identified bacterial pathogen. Copyright © 2012 International Society for Infectious Diseases. Published by Elsevier Ltd. All rights reserved.

  3. Association between C677T polymorphism of MTHFR gene and risk of amyotrophic lateral sclerosis: Polish population study and a meta-analysis. (United States)

    Żur-Wyrozumska, Kamila; Pera, Joanna; Dziubek, Anna; Sado, Małgorzata; Golenia, Aleksandra; Słowik, Agnieszka; Dziedzic, Tomasz

    Genetic factors play a role in pathogenesis of amyotrophic lateral sclerosis (ALS). A few studies demonstrated that the TT genotype of C677T polymorphism of the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene can increase the risk of sporadic ALS. The aim of our study was to determine the relationship between C677T polymorphism of MTHFR gene and the risk of sporadic ALS in Polish population and to perform the meta-analysis assessing the significance this polymorphism for the risk of ALS in Caucasian population. We included 251 patients with ALS and 500 control subjects recruited from Polish population and performed the meta-analysis of published data from Caucasian population. MTHFR C677T polymorphism was genotyped using a TaqMan assay and 7900HT Fast real Time PCR System. The frequency of genotypes did not differ significantly between Polish ALS patients and control subjects (CC: 45.0 vs 45.8%, CT: 48.2 vs 45.0%, TT: 6.8 vs 9.2%, P=0.46). The meta-analysis including 863 ALS patients and 1362 controls revealed that TT genotype increases the risk of sporadic ALS in Caucasian population. Although we did not find the association between C677T polymorphism of MTHRF gene and risk of ALS in Polish population, the results of meta-analysis suggest that the TT genotype can be a genetic risk factor for ALS in Caucasian population.

  4. The prevalence of Nonsuicidal Self-Injury (NSSI in a representative sample of the German population

    Directory of Open Access Journals (Sweden)

    Paul L. Plener


    Full Text Available Abstract Background Non-suicidal self-injury (NSSI is a proposed new “condition for further study” in the DSM-5. To date no prevalence data has been available on this diagnostic entity from a representative sample of the general population. Methods A representative sample of the German population (N = 2509, mean age = 48.8 years, SD = 18.1, female 55.4 % completed the NSSI section of the German version of the Self-Injurious Thoughts and Behaviors Interview (SITBI-G. Results A history of NSSI at least once during lifetime was reported by 3.1 % of all participants, with higher lifetime prevalence rates in younger age groups. DSM-5 NSSI disorder criteria were met by 0.3 %. The most common function of NSSI was automatic negative reinforcement (e.g. to alleviate negative feelings. Conclusions To the best of our knowledge, this is the first study reporting rates for the proposed NSSI category in DSM-5 from a representative sample of the general population. In comparison to findings from community samples of adolescents, adults seem to have lower lifetime prevalence rates of NSSI, thus making it necessary to emphasize prevention and treatment efforts in younger age groups.

  5. Sex estimation from measurements of the first rib in a contemporary Polish population. (United States)

    Kubicka, Anna Maria; Piontek, Janusz


    The aim of this study was to evaluate the accuracy of sex assessment using measurements of the first rib from computed tomography (CT) to develop a discriminant formula. Four discriminant formulae were derived based on CT imaging of the right first rib of 85 female and 91 male Polish patients of known age and sex. In direct discriminant analysis, the first equation consisted of all first rib variables; the second included measurements of the rib body; the third comprised only two measurements of the sternal end of the first rib. The stepwise method selected the four best variables from all measurements. The discriminant function equation was then tested on a cross-validated group consisting of 23 females and 24 males. The direct discriminant analysis showed that sex assessment was possible in 81.5% of cases in the first group and in 91.5% in the cross-validated group when all variables for the first rib were included. The average accuracy for the original group for rib body and sternal end was 80.9 and 67.9%, respectively. The percentages of correctly assigned individuals for the functions based on the rib body and sternal end in the cross-validated group were 76.6 and 85.0%, respectively. Higher average accuracies were obtained for stepwise discriminant analysis: 83.1% for the original group and 91.2% for the cross-validated group. The exterior edge, anterior-posterior of the sternal end, and depth of the arc were the most reliable parameters. Our results suggest that the first rib is dimorphic and that the described method can be used for sex assessment.

  6. What distinguishes weight loss maintainers of the German Weight Control Registry from the general population? (United States)

    Feller, Silke; Müller, Astrid; Mayr, Andreas; Engeli, Stefan; Hilbert, Anja; de Zwaan, Martina


    Differences between successful long-term weight loss maintainers and the general population with regard to eating and weighing habits, non-normative eating behaviors, and eating-related and general psychopathological parameters are unknown. Self-identified weight loss maintainers from the German Weight Control Registry (GWCR, n = 494) were compared with a representative sample of the general German population (n = 2,129). The samples did not differ in current BMI. Using the same assessment instruments in both cohorts, a variety of eating-related and psychological variables were determined. The GWCR participants reported more self-weighing and higher eating frequency but less hot meal consumption and more eating-out-of-home. Binge eating, compensatory behaviors, and concerns about shape and weight were reported more often by successful weight loss maintainers. Scores of depression and worrying about health were slightly higher whereas severity of somatic symptoms was less pronounced in the GWCR participants. Overall, our data suggest that successful weight loss maintainers are characterized by more concerns about shape and weight, greater binge eating frequency, and higher use of compensatory behaviors. The latter suggests that weight loss maintenance might not only be achieved by healthy strategies but also by non-normative behaviors which might increase the vulnerability for weight regain. © 2015 The Obesity Society.

  7. Translation and validation of the vertigo symptom scale into German: A cultural adaption to a wider German-speaking population

    Directory of Open Access Journals (Sweden)

    Gloor-Juzi Thomas


    Full Text Available Abstract Background Dizziness and comorbid anxiety may cause severe disability of patients with vestibulopathy, but can be addressed effectively with rehabilitation. For an individually adapted treatment, a structured assessment is needed. The Vertigo Symptom Scale (VSS with two subscales assessing vertigo symptoms (VSS-VER and associated symptoms (VSS-AA might be used for this purpose. As there was no validated VSS available in German, the aim of the study was the translation and cross-cultural adaptation in German (VSS-G and the investigation of its reliability, internal and external validity. Methods The VSS was translated into German according to recognized guidelines. Psychometric properties were tested on 52 healthy controls and 202 participants with vestibulopathy. Internal validity and reliability were investigated with factor analysis, Cronbach’s α and ICC estimations. Discriminant validity was analysed with the Mann–Whitney-U-Test between patients and controls and the ROC-Curve. Convergent validity was estimated with the correlation with the Hospital Anxiety Subscale (HADS-A, Dizziness Handicap Inventory (DHI and frequency of dizziness. Results Internal validity: factor analysis confirmed the structure of two subscales. Reliability: VSS-G: α = 0.904 and ICC (CI =0.926 (0.826, 0.965. Discriminant validity: VSS-VER differentiate patients and controls ROC (CI =0.99 (0.98, 1.00. Convergent validity: VSS-G correlates with DHI (r = 0.554 and frequency (T = 0.317. HADS-A correlates with VSS-AA (r = 0.452 but not with VSS-VER (r = 0.186. Conclusions The VSS-G showed satisfactory psychometric properties to assess the severity of vertigo or vertigo-related symptoms. The VSS-VER can differentiate between healthy subjects and patients with vestibular disorders. The VSS-AA showed some screening properties with high sensitivity for patients with abnormal anxiety.

  8. Hierarchical genetic analysis of German cockroach (Blattella germanica populations from within buildings to across continents.

    Directory of Open Access Journals (Sweden)

    Edward L Vargo

    Full Text Available Understanding the population structure of species that disperse primarily by human transport is essential to predicting and controlling human-mediated spread of invasive species. The German cockroach (Blattella germanica is a widespread urban invader that can actively disperse within buildings but is spread solely by human-mediated dispersal over longer distances; however, its population structure is poorly understood. Using microsatellite markers we investigated population structure at several spatial scales, from populations within single apartment buildings to populations from several cities across the U.S. and Eurasia. Both traditional measures of genetic differentiation and Bayesian clustering methods revealed increasing levels of genetic differentiation at greater geographic scales. Our results are consistent with active dispersal of cockroaches largely limited to movement within a building. Their low levels of genetic differentiation, yet limited active spread between buildings, suggests a greater likelihood of human-mediated dispersal at more local scales (within a city than at larger spatial scales (within and between continents. About half the populations from across the U.S. clustered together with other U.S. populations, and isolation by distance was evident across the U.S. Levels of genetic differentiation among Eurasian cities were greater than those in the U.S. and greater than those between the U.S. and Eurasia, but no clear pattern of structure at the continent level was detected. MtDNA sequence variation was low and failed to reveal any geographical structure. The weak genetic structure detected here is likely due to a combination of historical admixture among populations and periodic population bottlenecks and founder events, but more extensive studies are needed to determine whether signatures of global movement may be present in this species.

  9. Post-Cranial Traumatic Injury Patterns in Two Medieval Polish Populations: The Effects of Lifestyle Differences. (United States)

    Agnew, Amanda M; Betsinger, Tracy K; Justus, Hedy M


    Traumatic injuries can be used as general indicators of activity patterns in past populations. This study tests the hypothesis that contemporaneous (10th-12th century) rural and urban populations in medieval Poland will have a significantly different prevalence of non-violent fractures. Traumatic injuries to the post-cranial skeleton were recorded for 180 adults from rural Giecz and for 96 adults from urban Poznań-Śródka. They were statistically analyzed by body region and individual skeletal element. Results reveal that Giecz had a significantly higher rate of trunk fractures than Poznań-Śródka (Fisher's exact, pmedieval Poland, activities associated with a rural lifestyle resulted in more injuries. These stress or accidental fractures, which are related to a high-risk setting, were not consistent with an urban lifestyle. Overall, agricultural populations like Giecz were engaged in a laborious lifestyle, reflected in a variety of injuries related to repetitive, high-risk activities. Although urban populations like Poznań engaged in craft specialization participated in repetitive activities, their lifestyle resulted in lesser fracture-risk.

    Monika eWilkosc


    Full Text Available Brain derived neurotrophic factor is considered to be connected with memory and learning through the processes of long term synaptic potentiation and synaptic plasticity. The aim of the study was to examine the relationship between precursor BDNF (proBNDF and mature BDNF (mBDNF serum levels and performance on Rey Auditory-Verbal Learning Test (RAVLT in 150 healthy volunteers. In addition, we have verified the relationships between serum concentration of both forms of BDNF and RAVLT with sociodemographic and lifestyle factors. We found no strong evidence for the correlation of proBDNF and mBDNF serum levels with performance on RAVLT in healthy Polish population in early and middle adulthood. We observed the mBDNF serum concentration to be higher in women compared with men. Moreover, we revealed higher mBDNF level to be connected with lower Body Mass Index (BMI. In turn, the results of RAVLT correlated with sociodemographic and lifestyle factors, such as: age, education, gender, BMI and smoking.

  11. Change of attitude and behaviour of the West-German population after the Chernobyl reactor accident

    As a result of the Chernobyl reactor accident, the West-German population has shown to be much more aware of the hazards emanating from environmental pollution and chemical or radioactive contamination of food. It could be observed that, on the whole, consumption of important basic food has been reduced, so that the population's supply with various, significant nutrients is expected to deteriorate. The nutrients to be mentioned in this context are primarily calcium, riboflavin, folic acid, and ascorbic acid. Investigations over the period May to July 1986 show that the reactor accident's impact on the food consumption behaviour subsides only slowly, and it remains to be seen to what extent changes and fluctuations in the population's nutritional behaviour will have to be taken as 'normal'. Hence some sort of nutritional deficiency can be expected among certain groups of the population, either temporarily or over a prolonged period. A National Survey of Food Consumption currently in preparation will yield more detailed insight into the whole process. (orig./MG) [de

  12. Mental health differences between German gay and bisexual men and population-based controls. (United States)

    Sattler, Frank A; Franke, Gabriele H; Christiansen, Hanna


    International studies have revealed that gay and bisexual men present more mental health problems than the general male population. Furthermore, there is evidence that minority stress predicts mental health problems in gay and bisexual men. The aim of the present study is to provide initial data on mental health differences in Germany and to analyze the effect of minority stress. Mental health data on n = 1903 German gay and bisexual men and n = 958 men from a population-based sample were assessed using a shortened version of the SCL-90-S. The mental health of the two samples was compared. Furthermore, a linear regression was conducted for the gay and bisexual sample: mental health was used as the criterion and minority stressors as predictors. As compared to our population sample, gay and bisexual men demonstrated more mental health problems with a moderate effect size. In the regression, minority stress predicted mental health problems in the gay and bisexual sample. We observed pronounced mental health differences between gay and bisexual men versus the population sample. These differences could be at least partly due to the minority stress gay and bisexual men face. Research should focus on how to reduce and cope with minority stress.

  16. The Germans revisiting Gakovo: Encounters, cooperation and reconciliation of the former and present local populations

    Directory of Open Access Journals (Sweden)

    Krel Aleksandar


    Full Text Available This paper presents a case study about a reunion of the evicted members of the German national minority in Vojvodina, who after almost five decades came to visit their homeland, and the local population in Gakovo. The case study attests about lengthy and very complicated process in resolving post-conflict situations. The process’ launch is dependent on the willingness of the individuals involved to face not only one’s own pain caused by the enemy, but also on ability to comprehend, during an encounter with “the dark side of one’s past”, sufferings and humiliation experienced by the adversary. Awareness and acceptance of one’s own responsibility in the conflict are a prerequisite for forgiveness and reconciliation of the opposing parties. The outcome of this process is uncertain to the very end and conditioned upon the entire network of interlocking political, economic and cultural factors.

    The abdominal vessels show a number of abnormalities and pathologies knowledge of which is important during open as well as laparoscopic surgeries. One of the most common vessels which pattern has many variations is the coeliac trunk. The present study was undertaken on homogeneous population to assess morphology of the coeliac trunk and to evaluate the possible variability of its branches. Standard abdominal multidetector computed tomography examinations were performed on a total of 1569 patients diagnosed by 2 radiologists independently; in case of doubts common assessment was performed. The coeliac trunk followed the classic pattern in 92.7% of the cases (1455/1569 of patients). The gastrosplenic trunk was detected in 4.1% of cases (64/1569); the hepatosplenic trunk in 2.2% of cases (34/1569); the coeliac-mesenteric trunk was observed in 0.5% of cases (8/1569); the hepatogastric trunk in 0.2% of cases (4/1569); the splenomesenteric trunk was detected in 0.1% of cases (2/1569). In the next 0.1% the coeliac trunk was absent. The hepatosplenomesenteric and the coeliac-colic trunk were not observed in the study population. Vascular anatomical abnormality is usually asymptomatic hovewer, its preoperative knowledge is helpful to reduce complications like vascular bleeding when dissecting the hapato-pancreatic region. The coeliac trunk and its branches can be fast and easy evaluated in computed tomography exams performed due to various symptoms from abdominal cavity.

  18. Cord blood levels of potentially neurotoxic pollutants (polychlorinated biphenyls, lead and cadmium) in the areas of Prague (Czech Republic) and Katowice (Poland). Comparison with reference values in The Netherlands. The Czech/Polish/Dutch/German Research Team. (United States)

    Janousek, V; Krijt, J; Malbohan, M; Cibula, D; Lukas, W; Zejda, J E; Lammers, W; Huisman, M; Boersma, E R; van der Paauw, C G


    In a preliminary study the levels of four non-planar polychlorinated biphenyls congeners (118, 138, 153 and 180), and of the toxic metals lead and cadmium, and their antagonist selenium and zinc were measured in cord blood from apparently healthy neonates from the region of Prague and Upper Silezia (Katowice). These "background" levels were compared with similar values from neonates in the Netherlands. It was found that the levels of three PCB congeners (138, 153 and 180) were significantly higher in the Prague samples than in the Netherlands; but in the Katowice group they were significantly lower. In Upper Silezia (Katowice) the values of the metals lead and cadmium, and in Prague those of cadmium and selenium were significantly higher than in the Netherlands. The importance of these findings is discussed. It is argued that neurotoxic effects of perinatal exposure can be expected to be more prominent in Central Europe than in Western European countries. A more thorough study is indicated and will be undertaken by a joint Czech/Polish/Dutch/German research group.

  19. Population decline in Polish and Czech cities during post-socialism? Looking behind the official statistics. (United States)

    Steinführer, Annett; Bierzynski, Adam; Grossmann, Katrin; Haase, Annegret; Kabisch, Sigrun; Klusácek, Petr


    The evolving debate on "urban shrinkage" mirrors an increasing interest in demographic phenomena on the part of urban scholars. This paper discusses ambiguous evidence about recent population decline in the large cities of Poland and the Czech Republic, with a particular focus on Łódz and Brno in general and their inner cities more specifically. By applying a mixed-method approach, the paper identifies indications of inner-city repopulation and socio-demographic diversification which are not yet apparent in register or census data. It is argued that there are indications of a silent transformation of traditional residential patterns and neighbourhoods in east central Europe. In the inner cities, this is reflected, amongst other things, by the presence of new households that may be called "transitory urbanites".

    Konarzewska, Magdalena; Spólnicka, Magdalena; Sołtyszewski, Ireneusz; Berent, Jarosław


    The paper presents the results of a population study on the locus HUMHUU, which is a non-coding fragment of human DNA built of four nucleotide repeats (CTTT)n, localized on the 16th chromosome. The studies, carried out on a group of 200 non-related individuals, showed the presence of 14 different alleles, from 150 to 200 bp in length. Biostatistical calculations demonstrated that the expected heterozygosity was 0,830301 +/- 0,018768, PD - 0,949156, PIC - 0,806888, PE - 0,662444, PE for motherless cases - 0,491305, and the average paternity index - 2,946389. The results obtained during the studies of the locus HUMHUU allow for recognizing it as a marker of personal identification useful for the needs of both criminalistics and disputed paternity testing.

  1. Prevalence and Correlates of Self-Harm in the German General Population (United States)

    Müller, Astrid; Claes, Laurence; Smits, Dirk; Brähler, Elmar; de Zwaan, Martina


    The study aimed at evaluating the psychometric properties of the German version of the Self- Harm Inventory (SHI) and examining the lifetime prevalence and correlates of self-harm in a representative German population sample (N = 2,507; age mean = 48.79, SD = 18.11; range 14 to 94 years; 55.5% women) using the SHI. All participants answered the German SHI, the short form of the Barratt Impulsiveness Scale (BIS-15), the ultra-brief Patient Health Questionnaire for Depression and Anxiety (PHQ-4), and provided sociodemographic information. The one-factorial structure of the SHI was replicated using a confirmatory factor analysis. Internal consistency coefficients were sufficient and in line with previous studies. Almost half of the sample (49%) acknowledged at least one self-harming behavior over the life-span, most frequently indirect forms of self-harm. The rate of participants who engaged in at least one SHI behavior was higher among men than women (51.6% vs. 46.9%, respectively, χ2 = 5.38, p = 0.020). Higher SHI scores were related to younger age, male gender, living alone, more symptoms of anxiety and depression (PHQ-4), higher impulsivity scores (BIS-15), and suffering from obesity grade 2. Women engaged more often in discreet forms of self-harm than men, e.g., preventing wounds from healing, exercising an injury, starving, and abusing laxatives. In terms of other indirect self-harming behaviors, men admitted more often driving recklessly, being promiscuous and losing a job on purpose, while women reported more frequently engaging in emotionally abusive relationships. With respect to direct self-harm, women were more likely to endorse suicide attempts and cutting, while men admitted more often head-banging. The findings suggest that self-harm constitutes a common problem. Future longitudinal studies are required to examine the natural course, sociodemographic and psychopathological risk factors, as well as possible time-trends of self-harming behaviors in more

    Katarzyna Malinowska


    Full Text Available The first signs of oral cancer may resemble developing infections in the mucous membranes, with throat cancer symptoms being similar to those of upper respiratory tract infections. This greatly hinders rapid diagnosis and treatment. Better knowledge of the changes occurring in the metabolism of folic acid can help in understanding the carcinogenesis affecting DNA methylation and genome stability. Polymorphisms in genes encoding enzymes involved in this pathway may influence enzyme activity and thereby interfere with the concentrations of homocysteine and S-adenosylmethionine, which are important for DNA synthesis and cellular methylation reactions. The aim of the study was to determine the risk of oral cancer associated with the TC2 C776G polymorphism, as determined in 119 patients. Genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP. The test genotype was found to correspond to the Hardy-Weinberg (HW equilibrium (p > 0.05. In our population G/G homozygosity of C776G TC2 gene polymorphism increases the risk of oral cancer; OR (odds ratio: 4.3875; 95% CI (confidence interval: 2.0518-9.319; p = 0.001. Regarding C/G genotype of the C776G TC2 gene, polymorphism also increases the risk of developing this cancer; OR 2.4146 95% CI: 1.2803-4.5541; p = 0.01.

  4. Differences in baseline lung cancer mortality between the German uranium miners cohort and the population of the former German Democratic Republic (1960-2003). (United States)

    Walsh, Linda; Dufey, Florian; Möhner, Matthias; Schnelzer, Maria; Tschense, Annemarie; Kreuzer, Michaela


    A previous analysis of the radon-related lung cancer mortality risk, in the German uranium miners cohort, using Poisson modeling techniques, noted internal (spontaneous) rates that were higher on average than the external rates by 16.5% (95% CI: 9%; 24%). The main purpose of the present paper is to investigate the nature of, and possible reasons for, this difference by comparing patterns in spontaneous lung cancer mortality rates in a cohort of male miners involved in uranium extraction at the former Wismut mining company in East Germany with national male rates from the former German Democratic Republic. The analysis is based on miner data for 3,001 lung cancer deaths, 1.76 million person-years for the period 1960-2003, and national rates covering the same calendar-year range. Simple "age-period-cohort" graphical analyses were applied to assess the main qualitative differences between the national and cohort baseline lung cancer rates. Some differences were found to occur mainly at higher attained ages above 70 years. Although many occupational risk factors may have contributed to these observed age differences, only the effects of smoking have been assessed here by applying the Peto-Lopez indirect method for calculating smoking attributability. It is inferred that the observed age differences could be due to the greater prevalence of smoking and more mature smoking epidemic in the Wismut cohort compared to the general population of the former German Democratic Republic. In view of these observed differences between external population-based rates and internal (spontaneous) cohort baseline lung cancer rates, it is strongly recommended to apply only the internal rates in future analyses of uranium miner cohorts. © Springer-Verlag 2010

    Computer-aided diagnostic (CAD) techniques aid physicians in better diagnosis of diseases by extracting objective and accurate diagnostic information from medical data. Hashimoto thyroiditis is the most common type of inflammation of the thyroid gland. The inflammation changes the structure of the thyroid tissue, and these changes are reflected as echogenic changes on ultrasound images. In this work, we propose a novel CAD system (a class of systems called ThyroScan) that extracts textural features from a thyroid sonogram and uses them to aid in the detection of Hashimoto thyroiditis. In this paradigm, we extracted grayscale features based on stationary wavelet transform from 232 normal and 294 Hashimoto thyroiditis-affected thyroid ultrasound images obtained from a Polish population. Significant features were selected using a Student t test. The resulting feature vectors were used to build and evaluate the following 4 classifiers using a 10-fold stratified cross-validation technique: support vector machine, decision tree, fuzzy classifier, and K-nearest neighbor. Using 7 significant features that characterized the textural changes in the images, the fuzzy classifier had the highest classification accuracy of 84.6%, sensitivity of 82.8%, specificity of 87.0%, and a positive predictive value of 88.9%. The proposed ThyroScan CAD system uses novel features to noninvasively detect the presence of Hashimoto thyroiditis on ultrasound images. Compared to manual interpretations of ultrasound images, the CAD system offers a more objective interpretation of the nature of the thyroid. The preliminary results presented in this work indicate the possibility of using such a CAD system in a clinical setting after evaluating it with larger databases in multicenter clinical trials.

    Full Text Available OBJECTIVE: Previous research has shown an association between certain personality characteristics and suicidality. Methodological differences including small sample sizes and missing adjustment for possible confounding factors could explain the varying results. The aim of this study was to assess the impact of the Big Five personality dimensions on suicidality in a representative population based sample of adults. METHOD: Interviews were conducted in a representative German population-based sample (n=2555 in 2011. Personality characteristics were assessed using the Big Five Inventory-10 (BFI-10 and suicide risk was assessed with the Suicidal Behaviors Questionnaire-Revised (SBQ-R. Multivariate logistic regression models were calculated adjusting for depression, anxiety, and various sociodemographic variables. RESULTS: Neuroticism and openness were significantly associated with suicide risk, while extraversion and conscientiousness were found to be protective. Significant sex differences were observed. For males, extraversion and conscientiousness were protective factors. Neuroticism and openness were found to be associated with suicide risk only in females. These associations remained significant after adjusting for covariates. CONCLUSION: The results highlight the role of personality dimensions as risk factors for suicide-related behaviors. Different personality dimensions are significantly associated with suicide-related behaviors even when adjusting for other known risk factors of suicidality.

  8. Validation of the Polish version of the World Health Organization Disability Assessment Schedule (WHODAS 2.0) in an elderly population (60-70 years old). (United States)

    Ćwirlej-Sozańska, Agnieszka; Wilmowska-Pietruszyńska, Anna; Sozański, Bernard


    To assess the reliability and validity of the Polish version of the 36-point World Health Organization Disability Assessment Schedule (WHODAS 2.0) in an elderly population. One thousand randomly selected individuals, aged 60-70 years, living in south-eastern Poland were assessed using the Polish version of the WHODAS 2.0. The analysis confirmed the high reliability and validity of the tool. Cronbach's α index was 0.89. The tool had high stability, and the correlation between test and retest results was high. The relevance of the domain selection was high or very high. A factor analysis confirmed the relevance of assigning questions to domains. High theoretical relevance was also demonstrated. Statistically significant differences between those who were and were not suffering from health problems were observed. An analysis of the internal structure of the WHODAS 2.0 revealed strong correlations between the components of each domain and the final result. The Polish version of the WHODAS 2.0 showed high reliability and validity; thus, it can be used to assess health, functioning and disability in the elderly population of Poland.

  9. Cross-cultural measurement invariance of the General Health Questionnaire-12 in a German and a Colombian population sample. (United States)

    Romppel, Matthias; Hinz, Andreas; Finck, Carolyn; Young, Jeremy; Brähler, Elmar; Glaesmer, Heide


    While the General Health Questionnaire, 12-item version (GHQ-12) has been widely used in cross-cultural comparisons, rigorous tests of the measurement equivalence of different language versions are still lacking. Thus, our study aims at investigating configural, metric and scalar invariance across the German and the Spanish version of the GHQ-12 in two population samples. The GHQ-12 was applied in two large-scale population-based samples in Germany (N = 1,977) and Colombia (N = 1,500). To investigate measurement equivalence, confirmatory factor analyses were conducted in both samples. In the German sample mean GHQ-12 total scores were higher than in the Colombian sample. A one-factor model including response bias on the negatively worded items showed superior fit in the German and the Colombian sample; thus both versions of the GHQ-12 showed configural invariance. Factor loadings and intercepts were not equal across both samples; thus GHQ-12 showed no metric and scalar invariance. As both versions of the GHQ-12 did not show measurement equivalence, it is not recommendable to compare both measures and to conclude that mental distress is higher in the German sample, although we do not know if the differences are attributable to measurement problems or represent a real difference in mental distress. The study underlines the importance of measurement equivalence in cross-cultural comparisons. Copyright © 2017 John Wiley & Sons, Ltd.

    Full Text Available Abstract Background The study aimed at presenting normative data for both parallel forms of the "Rasch-based Depression Screening (DESC", to examine its Rasch model conformity and convergent and divergent validity based on a representative sample of the German general population. Methods The sample was selected with the assistance of a demographic consulting company applying a face to face interview (N = 2509; mean age = 49.4, SD = 18.2; 55.8% women. Adherence to Rasch model assumptions was determined with analysis of Rasch model fit (infit and outfit, unidimensionality, local independence (principal component factor analysis of the residuals, PCFAR and differential item functioning (DIF with regard to participants' age and gender. Norm values were calculated. Convergent and divergent validity was determined through intercorrelations with the depression and anxiety subscales of the Hospital Anxiety and Depression Scale (HADS-D and HADS-A. Results Fit statistics were below critical values (rDESC-I = .61 and rDESC-II = .60, whereas correlations with HADS-A were rDESC-I = .62 and rDESC-II = .60. Conclusions This study provided further support for the psychometric quality of the DESC. Both forms of the DESC adhered to Rasch model assumptions and showed intercorrelations with HADS subscales that are in line with the literature. The presented normative data offer important advancements for the interpretation of the questionnaire scores and enhance its usefulness for clinical and research applications.

    Kristina M Michael


    Full Text Available The natural history of infections with many human papillomavirus (HPV types is poorly understood. Here, we describe for the first time the age- and sex-dependent antibody prevalence for 29 cutaneous and five mucosal HPV types from 15 species within five phylogenetic genera (alpha, beta, gamma, mu, nu in a general population. Sera from 1,797 German adults and children (758 males and 1,039 females between 1 and 82 years (median 37 years were analysed for antibodies to the major capsid protein L1 by Luminex-based multiplex serology. The first substantial HPV antibody reactions observed already in children and young adults are those to cutaneous types of the genera nu (HPV 41 and mu (HPV 1, 63. The antibody prevalence to mucosal high-risk types, most prominently HPV 16, was elevated after puberty in women but not in men and peaked between 25 and 34 years. Antibodies to beta and gamma papillomaviruses (PV were rare in children and increased homogeneously with age, with prevalence peaks at 40 and 60 years in women and 50 and 70 years in men. Antibodies to cutaneous alpha PV showed a heterogeneous age distribution. In summary, these data suggest three major seroprevalence patterns for HPV of phylogenetically distinct genera: antibodies to mu and nu skin PV appear early in life, those to mucosal alpha PV in women after puberty, and antibodies to beta as well as to gamma skin PV accumulate later in life.

  12. Changes in depression stigma after the Germanwings crash - Findings from German population surveys. (United States)

    von dem Knesebeck, Olaf; Mnich, Eva; Angermeyer, Matthias C; Kofahl, Christopher; Makowski, Anna


    Media coverage of the Germanwings plane crash intensely focused on the co-pilot's mental illness and was criticized for potentially increasing depression stigma. We explored whether stigma beliefs towards persons with depression changed in April 2015 (about one month after the crash) compared to 2014. Telephone surveys among the adult population were conducted in Munich, Germany (N=650 in 2014 and N=601 in 2015). In both surveys, four components of stigma were assessed: (1) characteristics ascribed to persons with a depression, (2) belief in a continuum of symptoms from mental health to mental illness, (3) emotional reactions to people afflicted by depression (fear, anger, and pro-social reactions), and (4) desire for social distance. Some stigmatizing attitudes have increased after the crash. More specifically, we found more pronounced changes in the attributes ascribed (stereotypes) and in the perceived separation from persons afflicted (continuum beliefs) than in the emotional reactions and the desire for social distance. However, overall increase in depression stigma was smaller than expected as changes were not statistically significant in the majority of the analyzed items. Due to the study design no causal interpretation of results is possible. Moreover, evidence presented is confined to a regional German sample. A single devastating event and related media coverage seem to have a limited impact on public stigmatizing attitudes. Copyright © 2015 Elsevier B.V. All rights reserved.

  13. Coexistence of the 677C>T and 1298A>C MTHFR polymorphisms and its significance in the population of Polish women. (United States)

    Wolski, Hubert; Kocięcka, Maria; Mrozikiewicz, Aleksandra E; Barlik, Magdalena; Kurzawińska, Grażyna


    The aim of the study was to evaluate the frequency of the 677C>T and 1298A>C polymorphisms of the methylenetetrahydrofolate reductase (MTHFR) gene, as well as the coexistence of both these genetic variants in women from the Polish population. A total of 662 women from the Polish population were enrolled in the study group. The frequency of the investigated genotypes of the 677C>T and 1298A>C polymorphisms of the MTHFR gene was analyzed with the use of PCR/RFLP methods. The frequency of the 677CC, 677CT and 677TT genotypes in the studied population of women was 50.60%, 39.88% and 9.52%, respectively As to the 1298AA, 1298AC and 1298CC genotypes, the obtained results were as follows: 42.75%, 47.88% and 9.37%, respectively (Tables II and III). Simultaneous analysis revealed the most frequent coexistence of 677CC/1298AC (28.85%), 677CT/1298AA (20.85%) and 677CT/1298AC (19.03%) genotypes. The coexistence of 677CC/1298AA (12.39%), 677CC/1298CC (9.37%) and 677TT/1298AA (9.51%) genotypes was observed less frequently In the studied population of Polish women, the coexistence of 677CT/1298CC, 677TT/1298AC and 677TT/1298CC genotypes has been not observed. The frequency and coexistence of genotypes of the 677C>T and 1298A>C MTHFR gene polymorphisms in the studied population of Polish women is similar to other North-European populations. Women carriers of the mutated variants of both, 677C>T and 1298A>C polymorphisms of the MTHFR gene should receive special perinatal care in order to prevent fetal defects and thrombosis-related complications during pregnancy It is vital to emphasize the significance of proper education of folate supplementation, especially in pregnant patients and women of reproductive age.

    The prevalence of allergic disorders, especially allergic rhinitis (AR), has dramatically increased in the past few decades and multicentre, standardized, randomized epidemiological studies are required to quantify this phenomenon in Poland. The aim of the study was to estimate the prevalence of rhinitis and allergic rhinitis in Poland. The ECAP study was conducted using the ECRHS II and ISAAC questionnaires translated into the Polish language and validated, in selected nine regions of Poland, including eight cities and one rural area. The respondents within the regions were selected by means of multistage proportional stratified random sampling based on the identity number (PESEL) as the operat. The survey was conducted in 20,454 subjects (response rate of 41.9%) and 18,617 questionnaires were valid. Approximately 25% of the subjects (n=4783) were subsequently evaluated by clinicians (response rate of 43.4%). Rhinitis was self-reported by 36.08% of the respondents (37.8% of 6- 7-year-olds, 34.5% of 13- 14-year-olds, and 36.0% of adults). The lowest prevalence rate was in the rural region (22.9%). Allergic rhinitis (AR) was self-reported by 22.54% of the respondents (23.6% of 6- 7-year-olds, 24.6% of 13- 14-year-olds, and 21.0% of adults). Again, the lowest prevalence rate was in the rural region (16.0%). AR was more frequent in males (24.0%) than in females (21.2%) (OR = 1.079; 95% CI: 1.044-1.116). AR was actually diagnosed by a clinician in 28.9%, including intermittent AR in 47.7% and persistent AR in 52.3%. Seasonal AR was diagnosed in 15.55%, and perennial rhinitis in 15.2%. Allergic rhinitis is common in Poland as it affects nearly 25% of the population and it is a major social problem. Standards of early detection and prevention of allergic rhinitis should be introduced.

    Ksiazek, K.


    The International Conferences 'PLASMA' have been organized in Poland every two years since 1993. The German-Polish Conferences on Plasma Diagnostics were started in 2002, and the French-Polish Seminars on Thermal Plasmas were initiated in 1997. To reduce a number of topical conferences and to improve an exchange of information among different plasma research groups it was agreed to organize for the first time the triple conference at the Opole University, Poland, on September 6-9, 2005. The chairman of the International Scientific Committee (ISC) was Professor Marek J. Sadowski from IPJ in Swierk, and the co-chairmen were Professor Thomas Klinger of the IPP-Greifswald and Professor Michel Dudeck of the CNRS-Orleans. The chairman of LOC was Professor Jozef Musielok of the Opole University. This conference was designed for interested scientists, engineers and students from all the countries, but particularly for these from the Central and Eastern Europe (see The scientific programme of the conference embraced almost all directions of plasma research and technology, i.e.: 1. Elementary processes and general theory of plasma; 2. Plasmas in tokamaks, stellerators and related experiments; 3. plasmas in Z-pinch and PF discharges; 4. Plasmas produced by intense laser beams; 5. Plasmas of micro-wave and glow discharges; 6. Plasmas in spark- and arc-discharges; 7. Plasmas in space; 8. Diagnostics and experimental facilities; 9. Applications of quasi-stationary and pulsed plasmas. Participants of the conference were 127 plasma experts (including 23 invited speakers) from 13 different countries, as well as several honorary guests from local authorities and the most important plasma research centers in Poland. Most numerous groups came from Poland (58 persons), Germany (15 persons), France (14 persons), Czech Republic (11 persons), Russia (7 persons), and Ukraine (6 persons). The participants came also from Belarus, Hungary, Iran, Japan

    Full Text Available Health-related quality of life (HRQoL is a key measure for evaluating health status in populations. Using the recent EQ-5D-5L for measurement, this study analyzed quality of life results and their stability over consecutive population surveys. Three cross-section surveys for representative samples of the general German population from 2012, 2013, and 2014 were evaluated using the EQ-5D-5L descriptive system and valuation by the Visual Analog Scale (VAS. Aggregated sample size reached 6074. The dimension with the highest prevalence of problems was pain/discomfort (31.7%. Compared with 2012 (59.3%, the percentage of participants in the best health state increased slightly in 2013 (63.4% and 2014 (62%. Over the 3-year period, diabetes and heart disease had the strongest negative influence on mean VAS result. The number of reported chronic diseases cumulatively reduced mean VAS. Extreme problems in one or more dimensions were stated by only 0.1%–0.2% of patients. Of the potential 247 health states with a problem score ≥20, only six were observed in the aggregated sample. HRQoL results were fairly stable over the 3 years, but the share of the population with no problems was not. Results from the aggregated sample may serve as updated reference values for the general German population.

    Full Text Available Data on prevalence and phenotypic consequences of nucleotide-binding oligomerisation domain 2/caspase recruitment domains 15 (NOD2/CARD15 variants in Crohn's disease (CD population in Poland and Bosnia and Herzegovina (B&H are nonexistent. We aimed to determine the prevalence of NOD2/CARD15 mutations and their association with disease phenotype in Polish and Bosnian patients with CD and in healthy controls. We prospectively recruited 86 CD patients and 83 controls in Poland and 30 CD patients and 30 controls in B&H, 229 in total. We determined the prevalence of NOD2/CARD15 mutations and their association with the disease phenotype according to Montreal classification. Participants were genotyped for Leu1007fsinsC and Gly908Arg mutations. At least one CD-associated allele was found in 29/86 (33.7% of Polish CD patients and in 9/83 (10.8% of healthy controls (p<0.001. In both CD patients and controls in Bosnian sample, at least one NOD2 mutation was found in equal number of patients (3/30; 10% with all of the NOD2 mutation positive CD patients being homozygous, while controls being heterozygous. In Polish sample, perianal disease was less frequent in CD patients with any NOD2 mutation (1/21; 4.8% compared to those without (11/41; 26.8%; p=0.046. Higher percentage of patients with NOD2 mutations had history of CD related surgery when compared with those without mutations (66.7% vs. 43.3%; p=0.05. The risk for CD is increased in patients with NOD2 mutations (Poland and especially in the presence of homozygous NOD2 mutations (Poland and Bosnia. The presence of variant NOD2 alleles is associated with increased need for surgery and reduced occurrence of perianal disease.

  18. German version of the intuitive eating scale: Psychometric evaluation and application to an eating disordered population. (United States)

    van Dyck, Zoé; Herbert, Beate M; Happ, Christian; Kleveman, Gillian V; Vögele, Claus


    Intuitive eating has been described to represent an adaptive eating behaviour that is characterised by eating in response to physiological hunger and satiety cues, rather than situational and emotional stimuli. The Intuitive Eating Scale-2 (IES-2) has been developed to measure such attitudes and behaviours on four subscales: unconditional permission to eat (UPE), eating for physical rather than emotional reasons (EPR), reliance on internal hunger and satiety cues (RHSC), and body-food choice congruence (B-FCC). The present study aimed at validating the psychometric properties of the German translation of the IES-2 in a large German-speaking sample. A second objective was to assess levels of intuitive eating in participants with an eating disorder diagnosis (anorexia nervosa, bulimia nervosa, or binge eating disorder). The proposed factor structure of the IES-2 could be confirmed for the German translation of the questionnaire. The total score and most subscale scores were negatively related to eating disorder symptomatology, problems in appetite and emotional awareness, body dissatisfaction, and self-objectification. Women with eating disorders had significantly lower values on all IES-2 subscale scores and the total score than women without an eating disorder diagnosis. Women with a binge eating disorder (BED) diagnosis had higher scores on the UPE subscale compared to participants with anorexia nervosa (AN) or bulimia nervosa (BN), and those diagnosed with AN had higher scores on the EPR subscale than individuals with BN or BED. We conclude that the German IES-2 constitutes a useful self-report instrument for the assessment of intuitive eating in German-speaking samples. Further studies are warranted to evaluate psychometric properties of the IES-2 in different samples, and to investigate its application in a clinical setting. Copyright © 2016 Elsevier Ltd.

  19. Polish 2010 growth references for school-aged children and adolescents. (United States)

    Kułaga, Zbigniew; Litwin, Mieczysław; Tkaczyk, Marcin; Palczewska, Iwona; Zajączkowska, Małgorzata; Zwolińska, Danuta; Krynicki, Tomasz; Wasilewska, Anna; Moczulska, Anna; Morawiec-Knysak, Aurelia; Barwicka, Katarzyna; Grajda, Aneta; Gurzkowska, Beata; Napieralska, Ewelina; Pan, Huiqi


    Growth references are useful in monitoring a child's growth, which is an essential part of child care. The aim of this paper was to provide updated growth references for Polish school-aged children and adolescents and show the prevalence of overweight and obesity among them. Growth references for height, weight, and body mass index (BMI) were constructed with the lambda, mu, sigma (LMS) method using data from a recent, large, population-representative sample of school-aged children and adolescents in Poland (n = 17,573). The prevalence of overweight and obesity according to the International Obesity Taskforce definition was determined with the use of LMSGrowth software. Updated growth references for Polish school-aged children and adolescents were compared with Polish growth references from the 1980s, the Warsaw 1996-1999 reference, German, and 2000 CDC references. A positive secular trend in height was observed in children and adolescents from 7 to 15 years of age. A significant shift of the upper tail of the BMI distribution occurred, especially in Polish boys at younger ages. The prevalence of overweight or obesity was 18.7% and 14.1% in school-aged boys and girls, respectively. The presented height, weight, and BMI references are based on a current, nationally representative sample of Polish children and adolescents without known disorders affecting growth. Changes in the body size of children and adolescents over the last three decades suggest an influence of the changing economical situation on anthropometric indices.

    Piotrowski, Walerian; Waśkiewicz, Anna; Cicha-Mikołajczyk, Alicja


    To develop a global cardiovascular disease (CVD) mortality risk model for the Polish population and to verify these data in the context of the SCORE risk algorithm. We analysed data obtained in two multicentre national population studies, the WOBASZ study which was conducted in 2003-2005 and included 14,769 subjects aged 20-74 years, and the WOBASZ Senior study which was conducted in 2007 and included 1096 subjects above 74 years of age. All these subjects were followed for survival status until 2012 and the cause of death was determined. The mean duration of follow-up was 8.2 years for WOBASZ study participants and about 5 years for WOBASZ Senior study participants. Overall, 1436 subjects died, including 568 due to CVD. For the purpose of our analysis of overall and CVD mortality, 15 established risk factors were selected. Survival was analysed separately in WOBASZ and WOBASZ Senior study participants. Statistical methods included descriptive statistics, Kaplan-Meier curves, Cox proportional hazard models, and the SCORE risk algorithm. Measure of incompatibility of the SCORE risk model to the Polish population was determined as the difference between mortality rates by the SCORE risk quartiles and the Cox approach. During the 8-year follow-up of the WOBASZ study population, mortality due to CVD was 38% among men and 31% among women. The most common causes of CVD mortality were ischaemic heart disease (IHD, 33%) followed by cerebro-vascular disease (17%) in men, and cerebrovascular disease (31%) followed by IHD (23%) in women. We found significant differences between men and women in regard to survival curves for both overall mortality and CVD mortality (p Senior study population, mortality due to CVD was 48% among men and 58% among women. The most common cause of CVD mortality in both men and women was IHD (29% and 24%, respectively), followed by cerebrovascular disease (16% and 21%, respectively). We found significant differences between men and women in regard

  1. Realization of personal values predicts mental health and satisfaction with life in a german population


    Ostermann, Miriam; Huffziger, Silke; Kleindienst, Nikolaus; Mata, Jutta; Schmahl, Christian; Beierlein, Constanze; Bohus, Martin; Lyssenko, Lisa


    Abstract: Living according to one's personal values is expected to promote mental health and satisfaction with life. However, there is scarce empirical research on the effects of the relative importance of values and their realization in daily life. We implemented a new measure to examine the realization of Schwartz's values and its correlation with mental health and satisfaction with life in two German online samples. Analysis of sample 1 (n = 6,989; 70.2% female) reveals that both the impor...

  2. Public Attitudes Toward Fiscal Consolidation: Evidence from a Representative German Population Survey


    Bernd Hayo; Florian Neumeier


    The poor state of public finances in many countries has led to calls for fiscal consolidation. In practice, implementing concrete consolidation measures appears to meet with public resistance, suggesting that the success of consolidation efforts strongly depends on the popularity of the chosen measures. To identify public attitudes toward fiscal consolidation and alternative consolidation measures, we conducted a survey among 2,000 German citizens. Applying ordered and multinominal logit mode...

  3. Eat healthy? Attitudes of the German population towards industrially produced cardioprotective food. (United States)

    Jung, F U C E; Luck-Sikorski, C; Krüger, M; Wiacek, C; Braun, P G; Engeli, S; Riedel-Heller, S G


    Cardiovascular disease (CVD) is likely to increase in incidence. Foods with cardioprotective functions, e.g. specific functional food, could reduce CVD risk factors and hence CVD incidence. Little is known about industrially modified foods with cardioprotective functions. In a large German sample (n = 1007), attitudes of consumers in Germany towards industrially produced cardioprotective food were assessed using Cluster analyses. Consumers were contacted via telephone and interviewed using questionnaires. Overall, about 25% knew about industrially produced food with cardioprotective function. Our analysis revealed a small but determined group of consumers who think very skeptical about cardioprotective products, but we also identified a favorable group. These two groups only differed in age, with the skeptical group being ten years older. The rising number of industrially modified products with potential cardioprotective benefit is met by skepticism and a lack of knowledge by German costumers. If large scale studies show health benefits of these products, these will need to be better communicated to German customers in order to address possible doubts or concerns and to encourage healthy eating habits in consumer eating behavior.

  4. Integrins AV and B8 Gene Polymorphisms and Risk for Intracerebral Hemorrhage in Greek and Polish Populations. (United States)

    Dardiotis, Efthimios; Siokas, Vasileios; Zafeiridis, Tilemachos; Paterakis, Konstantinos; Tsivgoulis, Georgios; Dardioti, Maria; Grigoriadis, Savas; Simeonidou, Constantina; Deretzi, Georgia; Zintzaras, Elias; Jagiella, Jeremiasz; Hadjigeorgiou, Georgios M


    Α limited number of genetic variants have been linked to the development of intracerebral hemorrhage (ICH). Ιntegrin AV and/or B8-deficient mice were found to develop ICH. The present candidate gene association study was designed to investigate possible influence of integrin AV (ITGAV) and integrin B8 (ITGB8) gene region polymorphisms on the risk of ICH. 1015 participants (250 Greek and 193 Polish patients with primary ICH and 250 Greek and 322 Polish controls) were included in the study. Using logistic regression analyses, 11 tag single nucleotide polymorphisms (SNPs) for ITGAV and 11 for ITGB8 gene were tested for associations with ICH risk, lobar ICH risk and non-lobar ICH after adjustment for age, gender, history of hypertension and country of origin. Linear regression models were used to test the effect of tag SNPs on the ICH age of onset. Correction for multiple comparisons was carried out. The rs7565633 tag SNP of the ITGAV gene was independently associated with the risk of lobar ICH in the codominant model of inheritance [odds ratio (95 % confidence interval (CI)) 0.56 (0.36-0.86), p = 0.0013]. Furthermore, heterozygous individuals of the rs10251386 and the rs10239099 of the ITGB8 gene had significantly lower age of ICH onset compared to the wild-type genotypes [regression coefficient (b) -3.884 (95 % CI -6.519, -1.249), p = 0.0039 and b = -4.502 (95 % CI -7.159, -1.845), p = 0.0009, respectively]. The present study provides preliminary indication for an influence of ITGAV gene tag SNP in the development of lobar ICH and of ITGB8 gene variants in the age of ICH onset.

  5. Attitudes of the German general population toward early diagnosis of dementia--results of a representative telephone survey.

    Tobias Luck

    Full Text Available BACKGROUND: Early detection of dementia has clearly improved. Even though none of the currently available treatments for the most common form of dementia, Alzheimer's dementia, promises a cure, early diagnosis provides several benefits for patients, caregivers, and health care systems. This study aimed to describe attitudes toward early diagnosis of dementia in the German general population. METHODS: A representative telephone survey of the German population aged 18+ years (n = 1,002 was conducted in 2011. RESULTS: The majority of respondents (69% would be willing to be examined for early diagnosis of dementia. Almost two thirds reported that they would prefer their general practitioner (GP as the first source of professional help. More than half of the respondents (55% stated their belief that dementia could be prevented. Respondents mostly indicated psychosocial prevention options. CONCLUSIONS: Our findings suggest that the general population in Germany is very open to early diagnosis of dementia; however, this seems connected with large expectations on the effectiveness of prevention options. Dementia awareness campaigns may be employed to carefully inform the public about the prevention options currently available and their efficacy. To exploit GPs' potential as a gatekeeper for early detection of dementia, their ability to identify patients with antecedent and mild stages of the disease must be improved.

  6. Combination Testing Using a Single MSH5 Variant alongside HLA Haplotypes Improves the Sensitivity of Predicting Coeliac Disease Risk in the Polish Population.

    Full Text Available Assessment of non-HLA variants alongside standard HLA testing was previously shown to improve the identification of potential coeliac disease (CD patients. We intended to identify new genetic variants associated with CD in the Polish population that would improve CD risk prediction when used alongside HLA haplotype analysis. DNA samples of 336 CD and 264 unrelated healthy controls were used to create DNA pools for a genome wide association study (GWAS. GWAS findings were validated with individual HLA tag single nucleotide polymorphism (SNP typing of 473 patients and 714 healthy controls. Association analysis using four HLA-tagging SNPs showed that, as was found in other populations, positive predicting genotypes (HLA-DQ2.5/DQ2.5, HLA-DQ2.5/DQ2.2, and HLA-DQ2.5/DQ8 were found at higher frequencies in CD patients than in healthy control individuals in the Polish population. Both CD-associated SNPs discovered by GWAS were found in the CD susceptibility region, confirming the previously-determined association of the major histocompatibility (MHC region with CD pathogenesis. The two most significant SNPs from the GWAS were rs9272346 (HLA-dependent; localized within 1 Kb of DQA1 and rs3130484 (HLA-independent; mapped to MSH5. Specificity of CD prediction using the four HLA-tagging SNPs achieved 92.9%, but sensitivity was only 45.5%. However, when a testing combination of the HLA-tagging SNPs and the MSH5 SNP was used, specificity decreased to 80%, and sensitivity increased to 74%. This study confirmed that improvement of CD risk prediction sensitivity could be achieved by including non-HLA SNPs alongside HLA SNPs in genetic testing.

  7. Analysis of Newly Identified and Rare Synonymous Genetic Variants in the RET Gene in Patients with Medullary Thyroid Carcinoma in Polish Population. (United States)

    Sromek, Maria; Czetwertyńska, Małgorzata; Tarasińska, Magdalena; Janiec-Jankowska, Aneta; Zub, Renata; Ćwikła, Maria; Nowakowska, Dorota; Chechlińska, Magdalena


    Gain-of-function germline mutations of the RET proto-oncogene are responsible for initiation of carcinogenesis within the thyroid gland and development of hereditary form of medullary thyroid carcinoma and MEN2 syndrome. Genotype-phenotype correlations are established for most RET mutations, but the importance of the synonymous changes in this gene remains debatable. We aimed to analyze RET gene variants in Polish population. Genetic testing for the RET gene variants was performed with standard methods in 585 people aged 1-85, including 448 patients with medullary thyroid carcinoma and 131 of their first- and second-degree relatives, as well as six patients suspected of MTC/MEN2. Besides the most frequent synonymous changes, p.Leu769Leu, p.Ser836Ser, and p.Ser904Ser, four rare changes-c.1827C>T (p.Cys609Cys), c.2364C>T (p.Ile788Ile), c.2418C>T (p.Tyr806Tyr), and c.2673G>A (p.Ser891Ser)-were found in the RET gene, in the Polish population. Two of the rare changes, p.Cys609Cys and p.Ile788Ile, had not been previously described. The frequency of molecular synonymous variants in the general population was evaluated by testing 400 anonymous blood samples of neonates. Our findings may contribute to a better understanding of the genetic diversity of the RET gene and the involvement of synonymous variants in this diversity.

    Directory of Open Access Journals (Sweden)

    Kostyashov Yuri


    Full Text Available On the basis of earlier unknown documents of the Soviet consulate in Königsberg retrieved from the Archive of the Foreign Policy of the Russian Federation, the author analyses relations between the USSR and Germany in 1925—1930. The author focuses on the role of the “Polish question”, which largely affected the nature of bilateral relations. The consulate documents indicate that Soviet diplomacy aspired to exploit the differences between Poland and Germany over a wide range of issues (the geopolitical situation of East Prussia, the position of national minorities, the problem of transit through the Polish corridor, the status of the Free city of Danzig, etc.. Soviet consuls carefully observed political life in Königsberg and the province. On the one hand, they paid attention to an increase in the nationalist and fascist attitudes. On the other hand, they emphasized the aspirations of the local political and business elite to develop economic cooperation with the Soviet Union. The People's Commissariat for Foreign Affairs tried to transform East Prussia into a Soviet lobby in the German government. These plans were not implemented at that time, but the 1920s ideas of cooperation between the two states on the anti-Polish basis were put into practice on the eve of World War II.

    Full Text Available Different types of childhood maltreatment, like emotional abuse, emotional neglect, physical abuse, physical neglect and sexual abuse are interrelated because of their co-occurrence. Different patterns of childhood abuse and neglect are associated with the degree of severity of mental disorders in adulthood. The purpose of this study was (a to identify different patterns of childhood maltreatment in a representative German community sample, (b to replicate the patterns of childhood neglect and abuse recently found in a clinical German sample, (c to examine whether participants reporting exposure to specific patterns of child maltreatment would report different levels of psychological distress, and (d to compare the results of the typological approach and the results of a cumulative risk model based on our data set.In a cross-sectional survey conducted in 2010, a representative random sample of 2504 German participants aged between 14 and 92 years completed the Childhood Trauma Questionnaire (CTQ. General anxiety and depression were assessed by standardized questionnaires (GAD-2, PHQ-2. Cluster analysis was conducted with the CTQ-subscales to identify different patterns of childhood maltreatment.Three different patterns of childhood abuse and neglect could be identified by cluster analysis. Cluster one showed low values on all CTQ-scales. Cluster two showed high values in emotional and physical neglect. Only cluster three showed high values in physical and sexual abuse. The three patterns of childhood maltreatment showed different degrees of depression (PHQ-2 and anxiety (GAD-2. Cluster one showed lowest levels of psychological distress, cluster three showed highest levels of mental distress.The results show that different types of childhood maltreatment are interrelated and can be grouped into specific patterns of childhood abuse and neglect, which are associated with differing severity of psychological distress in adulthood. The results

    Sklenarova, Halina; Schulz, Anja; Schuhmann, Petya; Osterheider, Michael; Neutze, Janina


    Prevalence of Internet use among adolescents is high, but little is known about the online sexual activities of German adolescents. This study aimed to describe the 12-month prevalence of German adolescents' online sexual experiences with a focus on Online Sexual Solicitation (OSS, subjectively negative online sexual experiences with a peer or any sexual online experience, positive or negative, with an adult). A sample of male and female adolescents aged 14-17 (N=2238) was recruited using online survey panel. The sample was representative for gender and education. Subjects completed an online survey reporting their online sexual activities (i.e., sexual conversation, exchanging pictures, and cybersex) with peers (14-17y.) and/or adults (≥18y.). Findings illustrated that 51.3% (n=1148) of adolescents had experienced online sexual activity, which mostly involved peers (n=969; 84.4%). In contrast, 23.2% (n=519) of the adolescents experienced OSS with 2.6% (n=57) reporting subjectively negative online sexual interactions with peers and 22.2% (n=490) reporting online sexual interactions with adults, of which 10.4% (n=51) were perceived as negative. The findings suggest that adolescents frequently engage in sexual interactions on the Internet with only a relatively small number perceiving such contacts as exploitative. In addition, females and adolescents with incomplete family situation, foreign nationality, higher education, homo- or bisexual orientation, and those without perceived social support reported OSS significantly more often.

  11. Coexistence of ACE (I/D) and PAI-1 (4G/5G) gene variants in recurrent miscarriage in Polish population. (United States)

    Kurzawińska, Grażyna; Barlik, Magdalena; Drews, Krzysztof; Różycka, Agata; Seremak-Mrozikiewicz, Agnieszka; Ożarowski, Marcin; Klejewski, Andrzej; Czerny, Bogusław; Wolski, Hubert


    Recurrent miscarriage (RM) is one of the most common obstetric complications. Numerous studies have suggested that genetic variants leading to an impaired balance between coagulation and fibrinolysis may contribute to elevated risk of pregnancy loss. The aim of the study was to investigate a possible association between angiotensin-converting enzyme (ACE, rs1799752) I/D and plasminogen activator inhibitor type 1 (PAI-1, rs1799768) 4G/5G polymorphisms with RM among Polish women. DNA was extracted from peripheral blood samples of 152 women with a history of ≥ 2 consecutive pregnancy losses before 22 weeks of gestation, and 180 healthy controls with at least 1 live birth at term and no history of pregnancy loss. Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) were used to identify the polymorphisms. No statistically significant differences were found in genotype and allele frequencies of the studied polymorphisms. The most relevant difference between the study group and controls was found for the ID genotype distribution of the ACE gene (52.6 vs. 46.7%, OR = 1.27, p = 0.28). The analysis of genotype coexistence revealed a higher incidence of the combination of the ACE II and the PAI-1 4G/4G genotypes in the control group (10.0 vs.5.9% in control group; p = 0.17). The obtained results suggest no apparent association between the ACE I/D, PAI-1 4G/5G polymorphisms and increased RM susceptibility in the analyzed Polish population.

    Forensic age estimation in living subjects has gained increasing significance in recent years. In dental age estimation, tooth eruption is a parameter of developmental morphology that can be analyzed by either clinical examination or by evaluation of dental X-rays. In the present study, we determined the stage of wisdom tooth eruption in 144 male and 522 female German subjects aged 12-26 years based on radiological evidence from 666 conventional orthopantomograms. The results presented here provide useful data on the age of alveolar, gingival, and complete emergence of the third molars in the occlusal plane that can be utilized for the forensic estimation of the minimum and most probable ages of individuals under investigation.

    Olze, Andreas; Peschke, Corinna; Schulz, Ronald; Schmeling, Andreas


    The evaluation of the eruption status of the wisdom teeth constitutes a significant component of the spectrum of dental methods available for purposes of forensic age diagnostics. In the present study, the status of wisdom tooth eruption was identified in 606 conventionally created orthopantomograms of 515 female and 91 male Germans, divided by sex and tooth, using a modified classification comprising four stages. Instead of the original stage C (gingival eruption) which cannot always be reliably identified on X-ray images of suboptimal quality, stage C of the modified classification was considered reached when the erupting wisdom tooth had reached at least half the length of the crown of the adjacent second molar, without however having yet reached the occlusal plane. The new stage classification is especially recommended for age estimation based on X-ray images in which a conclusive delimitation of the gingiva is not possible.

  14. The Road to Negative Behavior: Discriminatory Intentions in the German Population

    Directory of Open Access Journals (Sweden)

    Ulrich Wagner


    Full Text Available This study analyzes discriminatory intentions shared by members of the German majority against several outgroups in Germany. Patterns of discriminatory intentions against various minority groups were investigated for several indicators, including gender, age, and political orientation, by means of a representative survey (N = 1,778. The relationship between prejudices and discriminatory intentions against different target groups was also analyzed. Prejudice and discriminatory intentions show moderate but consistently positive correlations in relation to one and the same target group. Moreover, it was found that discriminatory intentions against one outgroup are related to hostile attitudes towards other outgroups, too. The results support the hypothesis of a syndrome of group-focused enmity.

  15. The prevalence of compulsive hoarding and its association with compulsive buying in a German population-based sample. (United States)

    Mueller, Astrid; Mitchell, James E; Crosby, Ross D; Glaesmer, Heide; de Zwaan, Martina


    The aims of the study were to estimate the prevalence rate of compulsive hoarding, and to determine the association between compulsive hoarding and compulsive buying in a nationally representative sample of the German population (N = 2307). Compulsive hoarding was assessed with the German version of the Saving Inventory-Revised (SI-R; Frost, R.O., Steketee, G., & Grisham, J. (2004). Measurement of compulsive hoarding: saving inventory-revised. Behaviour Research and Therapy, 42, 1163-1182.). The point prevalence of compulsive hoarding was estimated to be 4.6%. Individuals with compulsive hoarding did not differ significantly from those without compulsive hoarding regarding age, gender, and other sociodemographic characteristics. Significant correlations were found between the compulsive hoarding and the compulsive buying measures. Participants with compulsive hoarding reported a higher propensity to compulsive buying than respondents without hoarding. About two thirds of participants classified as having compulsive hoarding were also defined as suffering from compulsive buying. In summary, these results suggest that compulsive hoarding may be relatively prevalent in Germany and they confirm the close association between compulsive hoarding and compulsive buying through the investigation of a large scale representative sample.

  16. Changes in body weight and obesity status in German adults: results of seven population-based prospective studies. (United States)

    The objective of this study was to quantify body weight changes in German adult populations during the past decades. Longitudinal analysis of seven cohort studies covering different age ranges between 18 and 83 years. Baseline examinations were between 1994 and 2007 and follow-up durations between 4.0 and 11.9 years. For each study, mean change in body weight per year and 10-year change in body mass index (BMI) classification were analyzed. For the middle age group of 45-64 years, meta-analysis was conducted to obtain an overall estimate for Germany. Among men weight gain was highest in the youngest participants and decreased with advancing age. Among women weight gain was on a stable high level among those younger than 45 years and decreased at older age. Within 10 years, 30-40% of middle-aged participants with normal baseline weight became pre-obese or obese and 20-25% of those with pre-obesity at baseline became obese, whereas >80% of persons who were obese at baseline remained obese over time. The estimated average weight change in adults aged 45-64 years was 0.25 (95% confidence interval (CI): 0.18-0.33) kg/year among men and 0.24 (0.17-0.30) kg/year among women. We could observe a moderate weight gain over the past years in German middle-aged populations of 0.25 kg/year. Obesity prevention needs to be targeted to specific subgroups in the population, especially to younger adults, who seem to be most vulnerable for gaining weight. Obesity intervention needs to be improved, as the majority of obese adults remained obese over time.

    Schlack, R; Rüdel, J; Karger, A; Hölling, H


    Violence is of considerable relevance to Public Health. It was the aim of the violence screening implemented as part of the"German Health Interview and Examination Survey for Adults" (DEGS1) to assess data on physical and psychological violence in various social environments (partnership, family, workplace, public space). For the first time as part of a nationally representative health survey, the data was collected from the perspective of victim and perpetrator both among women and men. The study population was comprised of 5939 participants aged between 18 and 64 years. Approximately every 20th participant reported being the victim of physical violence in the preceding 12 months, men significantly more frequently than women. With regard to the frequency of being the perpetrator of physical violence (overall prevalence 3.7 %) there were no significant differences between the sexes. Psychological victimisation was reported by every fifth participant and overall perpetrating psychological violence was reported by every tenth. Women tended to be more frequent the victims but they were also significantly more frequently the perpetrators of both physical and psychological violence in the domestic area (partnership, family). In contrast, men more frequently report being both the perpetrator and the victim of violence in the workplace and in the public space. Young adults between 18 and 29 years as well as persons of low socioeconomic status were consistently more frequently affected by violence although there were exceptions with regard to psychological violent victimisation. More than three-quarters of the victims of physical violence reported being greatly or extremely affected in their well-being by the violence and in the case of psychological violence the rate was about approximately 60%. Overall, the traumatic experience as a consequence of experiencing physical and psychological violence was considerably higher, especially in the case of domestic violence

    Boros Lech


    Full Text Available The main purpose of this work was to analyse the morphological, phenological and agronomical variability among common bean local populations from The National Centre for Plant Genetic Resources, Polish Genebank, in order to know the relation among them, and to identify potentially useful accessions for future production and breeding. A considerable genotypic variation for number of seeds per plant, number of pods per plant and weight of seeds per plant were found. Studied bean accessions differed significantly in terms of thousand seeds weight (TSW as well as severity of bacterial halo blight and anthracnose, the major bean diseases. The lowest genotypic diversity was found for the percentage of protein in the seeds, the length of the vegetation period and lodging. The cluster analysis allowed identification of five groups of bean accessions. Genotypes from the first cluster (POLPOD 98-77, KOS 002 and Raba cv. and from the second cluster (WUKR 06-573a, KRA 4, WUKR 06-0534 together with Prosna cv. are of the highest usefulness for breeding purposes. There was no grouping of local populations depending on region of origin.

    Although several studies show that JIA-patients have significantly lower employment rates than the general population, the research on educational and occupational attainments in patients with juvenile idiopathic arthritis (JIA) remain conflicting most likely due to small sample sizes. Therefore, aim of this study is to compare the educational achievements and employment status of 3698 JIA-patients with the German general population (GGP). "SEPIA" was a large cross-sectional study on the current status of a historic cohort of JIA-patients treated in a single center between 1952 and 2010. For the analyses of education and employment a sub-cohort was extracted, including only adult cases with a confirmed diagnosis of JIA (N = 2696). Participants were asked to fill out a standardized written questionnaire on education and employment. Outcome measures (education/unemployment) were directly standardized to the GGP using data obtained from the National Educational Panel Study 2013 (N = 11,728) and the German Unemployment Statistics 2012 of the Federal Statistical Office (N = 42,791,000). After age- and sex-standardization, 3% (95% Confidence Interval 1.9 to 4.1%) more of the JIA-patients (26%) than of the GGP (23%) had only reached primary education. In contrast, parents of JIA-patients had similar levels of education as parents in the GGP. With a standardized difference of 0.2% (95% CI: 0.16 to 0.19%), the unemployment rate in JIA-patients was slightly, but not significantly higher than in the GGP. Stratifying for disease duration and the current treatment status, differences were confirmed for persons diagnosed before 2001, whilst for patients diagnosed after 2000, differences were found only in JIA-patients with ongoing disease. Medium and high educational achievements did not differ statistically significant between JIA patients and the GPP. Educational achievements in German JIA-patients are significantly lower than in the GGP. Furthermore we were able to

    Zhan, Yiqiang; Holtfreter, Birte; Meisel, Peter; Hoffmann, Thomas; Micheelis, Wolfgang; Dietrich, Thomas; Kocher, Thomas


    To develop models for periodontitis using self-reported questions and to validate them externally. The Study of Health in Pomerania (SHIP-0) was used for model development. Periodontitis was defined according to the definitions of the Center for Disease Control and Prevention-American Academy of Periodontology, the 5th European Workshop in Periodontology, and Dietrich et al. (≥2 teeth with inter-proximal clinical attachment loss of ≥4 mm and 6 mm as moderate and severe periodontitis) respectively. These models were validated in SHIP-Trend and the Fourth German Oral Health Study (DMS IV). Final models included age, gender, education, smoking, bleeding on brushing and self-reported presence of mobile teeth. Concordance-statistics (C-statistics) of the final models from SHIP-0 were 0.84, 0.82 and 0.85 for the three definitions respectively. Validation in SHIP-Trend revealed C-statistics of 0.82, 0.81 and 0.82 respectively. As bleeding on brushing and presence of mobile teeth were unavailable in DMS IV, reduced models were developed. C-statistics of reduced models were 0.82, 0.81 and 0.83 respectively. Validation in DMS IV revealed C-statistics of 0.72, 0.78 and 0.72 for the three definitions respectively. All p values of the goodness-of-fit tests were >0.05. The models yielded a moderate usefulness for prediction of periodontitis. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  6. Smoking related cancers and loci at chromosomes 15q25, 5p15, 6p22.1 and 6p21.33 in the Polish population.

    Directory of Open Access Journals (Sweden)

    Ewa Jaworowska

    Full Text Available Genetic factors associated with the risk of smoking related cancers have until recently remained elusive. Since the publication of a genome-wide association study (GWAS on lung cancer new genetic loci have been identified that appear to be associated with disease risk. In this replication study we genotyped 14 single nucleotide polymorphisms (SNPs located at the 5p12.3-p15.33, 6p21.3-p22.1, 6q23-q27 and 15q25.1 loci in 874 lung, 450 bladder, 418 laryngeal cancer cases and cancer-free controls, matched by year of birth and sex to the cases. Our results revealed that loci in the chromosome region 15q25.1 (rs16969968[A], rs8034191[G] and 5p15 (rs402710[T] are associated with lung cancer risk in the Polish population (smoking status adjusted OR = 1.45, 1.35, 0.77; p ≤ 0.0001, 0.0005, 0.002; 95%CI 1.23-1.72, 1.14-1.59, 0.66-0.91 respectively. None of the other regions analyzed herein were implicated in the risk of lung, bladder or laryngeal cancer. This study supports previous findings on lung cancer but fails to show association of SNPs located in 15q25.1 and 5p15 region with other smoking related cancers like bladder and laryngeal cancer.

  7. A new view on the European feline population from mtDNA analysis in Polish domestic cats. (United States)

    Głażewska, Iwona; Kijewski, Tomasz


    Domestic cats from Eastern Europe have been poorly represented in studies on mitochondrial DNA diversity for forensic purposes until now. The aim of the present study was to contribute to closing this gap. The genetic structure and the origin of a cat population in Poland were examined against the background of human migrations over the centuries. One hundred and eighty-one cats from animal shelters in seven cities were genotyped. Twenty-one mtDNA haplotypes were found, with only one haplotype present in each of the populations, at an average frequency of 63.54%, and 13 haplotypes being found only in single populations. The analysis revealed the unexpectedly high frequency of haplotype PL02, in previous studies observed only in single cats. Differences in the number of the haplotypes, from four to eight, were observed among the shelters. The findings are discussed with regard to a world-wide database of feline sequences and to the complicated history of Poland. The study underscores the necessity of creating local databases of haplotypes that are of high evidentiary value to the forensic investigations conducted in a given country.

  8. Effort-Reward Imbalance and Mental Health Problems in 1074 German Teachers, Compared with Those in the General Population. (United States)

    Hinz, Andreas; Zenger, Markus; Brähler, Elmar; Spitzer, Silvia; Scheuch, Klaus; Seibt, Reingard


    High degrees of premature retirement among teachers warrant investigating the occupational burden and the mental health status of this profession. A sample of 1074 German teachers participated in this study. Two samples of the general population (N = 824 and N = 792) were used as comparison groups. Work distress was assessed with the Effort-Reward-Imbalance questionnaire, and mental health problems were measured with the General Health Questionnaire (GHQ-12). Teachers reported more effort-reward imbalance (M = 0.64) compared with the general population (M = 0.57), and they perceived more mental health problems (GHQ: M = 12.1) than the comparison group (M = 9.5). School type was not associated with work stress and mental health. Teachers with leading functions perceived high degrees of effort and reward, resulting in a moderate effort-reward ratio and no heightened mental health problems. Teachers working full time reported more effort than teachers working part time, but the reward mean values of both groups were similar. This results in a somewhat unfavourable effort-reward ratio of teachers working full time. Moreover, teachers working full time reported more mental health problems. The results support the appropriateness of the effort-reward conception, applied to the profession of teachers. The higher degree of effort-reward imbalance and the level of mental health problems warrant preventive measures. Copyright © 2014 John Wiley & Sons, Ltd. Copyright © 2014 John Wiley & Sons, Ltd.

  9. Cancer incidence in ethnic German migrants from the Former Soviet Union in comparison to the host population. (United States)

    Winkler, Volker; Holleczek, Bernd; Stegmaier, Christa; Becher, Heiko


    To investigate cancer incidence patterns among ethnic German migrants (Aussiedler) from the Former Soviet Union, a large migrant group in Germany, in comparison to autochthonous Saarland population over a 20 year observation period. Data were obtained from a cohort of Aussiedler residing in the federal state of Saarland (n=18,619). Cancer incidence and vital status were ascertained through record linkage with the Saarland Cancer Registry and local population registries. During the follow up period from 1990 to 2009 we observed 638 incident diagnoses of malignant neoplasms (except non-melanoma skin cancer). The overall standardized incidence ratio (SIR) was 0.98 (95% confidence interval 0.92, 1.04). However, site-specific SIRs revealed great variation. Stomach cancer incidence was significantly higher among Aussiedler. Lung cancer was elevated for males, but lower among females. Additionally, diagnoses for colorectal cancer among males were significantly lower. Age-standardized rates (ASRs) over time show not all cancer rates of Aussiedler attenuate as expected to Saarland rates. For example, lung and prostate cancer incidence rates show increasing disparity from Saarland rates and female breast cancer incidence develops in parallel. Furthermore, ASR for overall cancer incidence of Aussiedler shows a yearly decrease (p=0.06) whereas Saarland rates remain stable. Aussiedler incidence rates reflect incidence pattern observed in their countries of origin. Copyright © 2013 Elsevier Ltd. All rights reserved.

  10. Persistence of nasal colonization with human pathogenic bacteria and associated antimicrobial resistance in the German general population

    Full Text Available The nares represent an important bacterial reservoir for endogenous infections. This study aimed to assess the prevalence of nasal colonization by different important pathogens, the associated antimicrobial susceptibility and risk factors. We performed a prospective cohort study among 1878 nonhospitalized volunteers recruited from the general population in Germany. Participants provided nasal swabs at three time points (each separated by 4–6 months. Staphylococcus aureus, Enterobacteriaceae and important nonfermenters were cultured and subjected to susceptibility testing. Factors potentially influencing bacterial colonization patterns were assessed. The overall prevalence of S. aureus, Enterobacteriaceae and nonfermenters was 41.0, 33.4 and 3.7%, respectively. Thirteen participants (0.7% were colonized with methicillin-resistant S. aureus. Enterobacteriaceae were mostly (>99% susceptible against ciprofloxacin and carbapenems (100%. Extended-spectrum β-lactamase–producing isolates were not detected among Klebsiella oxytoca, Klebsiella pneumoniae and Escherichia coli. Several lifestyle- and health-related factors (e.g. household size, travel, livestock density of the residential area or occupational livestock contact, atopic dermatitis, antidepressant or anti-infective drugs were associated with colonization by different microorganisms. This study unexpectedly demonstrated high nasal colonization rates with Enterobacteriaceae in the German general population, but rates of antibiotic resistance were low. Methicillin-resistant S. aureus carriage was rare but highly associated with occupational livestock contact.

    In contrast to other European countries, dermatologists in Germany provide health care for a broad spectrum of diseases of the skin and mucous membranes. Current population-based data on the perception of dermatology were lacking to date. Analysis of the perception of dermatology from the general population's perspective with regard to utilization, satisfaction and responsibility. Nation-wide survey on awareness, utilization, rating and image of dermatology in October 2014 through computer-assisted telephone interviews on a representative sample of the adult general population (n = 1015), performed by the FORSA institute. Dermatologists as a medical specialist group are familiar to 88% of the population (2002: 65%), and approx. 82% of respondents underwent dermatological treatment in the past. Satisfaction with this treatment is high to very high in 80-90% of respondents. The majority (60-80%) name dermatologists as the desired primary provider of care for the largest share of common skin diseases. For allergic diseases, mucous membrane diseases, venous disorders and paediatric skin diseases, this rate is significantly below 50%. In Germany, dermatologists are perceived and valued as providers of care. In the case of skin cancer and chronic inflammatory skin diseases, they are experienced as primary care givers, whereas they are associated less frequently than their competence would justify with providing treatment for allergic and mucous membrane diseases and venous disorders. Further education of the general public and medical profession is required. © 2017 European Academy of Dermatology and Venereology.

  13. Identification and dissection of four major QTL affecting milk fat content in the German Holstein-Friesian population.

    Directory of Open Access Journals (Sweden)

    Xiaolong Wang

    Full Text Available Milk composition traits exhibit a complex genetic architecture with a small number of major quantitative trait loci (QTL explaining a large fraction of the genetic variation and numerous QTL with minor effects. In order to identify QTL for milk fat percentage (FP in the German Holstein-Friesian (HF population, a genome-wide association study (GWAS was performed. The study population consisted of 2327 progeny-tested bulls. Genotypes were available for 44,280 SNPs. Phenotypes in the form of estimated breeding values (EBVs for FP were used as highly heritable traits. A variance components-based approach was used to account for population stratification. The GWAS identified four major QTL regions explaining 46.18% of the FP EBV variance. Besides two previously known FP QTL on BTA14 (P = 8.91×10-(198 and BTA20 (P = 7.03×10(-12 within DGAT1 and GHR, respectively, we uncovered two additional QTL regions on BTA5 (P = 2.00×10(-13 and BTA27 (P = 9.83×10(-5 encompassing EPS8 and GPAT4, respectively. EPS8 and GPAT4 are involved in lipid metabolism in mammals. Re-sequencing of EPS8 and GPAT4 revealed 50 polymorphisms. Genotypes for five of them were inferred for the entire study population. Two polymorphisms affecting potential transcription factor binding sites of EPS8 (P = 1.40×10(-12 and GPAT4 (P = 5.18×10(-5, respectively, were highly significantly associated with the FP EBV. Our results provide evidence that alteration of regulatory sites is an important aspect of genetic variation of complex traits in cattle.

  14. The prevalence of mutations in the gene encoding filaggrin in the population of Polish patients with atopic dermatitis

    Magdalena Woźniak


    Full Text Available Introduction : The genetic background of atopic dermatitis (AD is complex, involves many genes and their participation varies in varied populations, and depends on the intensity and course of a disease. Changes in the nucleotide sequence of the FLG gene and a reduced number or a deficit of the functional product of processed profilaggrin can be one of risk factors for atopic dermatitis. Aim : To determine the prevalence of R501X and 2282del4 mutations of the FLG gene in patients with AD. Material and methods : The studied group included 60 patients with clinically diagnosed AD, and the control group included 61 healthy volunteers. The study protocol included collection of biological material for tests, DNA isolation and evaluation of its quality and quantity, and PCR amplification of the isolated genetic material. Results : In the studied group, both changes in the nucleotide sequence of the FLG gene were detected and in the control group no tested mutations were detected. In 18 (30% patients with AD, 22 mutations (4 heterozygous and 1 homozygous ones of R501X and 10 heterozygous and 7 homozygous ones of 2282del4 were detected. Conclusions : A high rate of mutations of the FLG gene in patients with clinically diagnosed AD and pathologically dry skin was observed in the studied population. The 2282del4 mutation occurred more often than R501X.

  17. Applying the effort-reward imbalance model to household and family work: a population-based study of German mothers. (United States)

    Sperlich, Stefanie; Peter, Richard; Geyer, Siegfried


    This paper reports on results of a newly developed questionnaire for the assessment of effort-reward imbalance (ERI) in unpaid household and family work. Using a cross-sectional population-based survey of German mothers (n = 3129) the dimensional structure of the theoretical ERI model was validated by means of Confirmatory Factor Analysis (CFA). Analyses of Variance were computed to examine relationships between ERI and social factors and health outcomes. CFA revealed good psychometric properties indicating that the subscale 'effort' is based on one latent factor and the subscale 'reward' is composed of four dimensions: 'intrinsic value of family and household work', 'societal esteem', 'recognition from the partner', and 'affection from the child(ren)'. About 19.3% of mothers perceived lack of reciprocity and 23.8% showed high rates of overcommitment in terms of inability to withdraw from household and family obligations. Socially disadvantaged mothers were at higher risk of ERI, in particular with respect to the perception of low societal esteem. Gender inequality in the division of household and family work and work-family conflict accounted most for ERI in household and family work. Analogous to ERI in paid work we could demonstrate that ERI affects self-rated health, somatic complaints, mental health and, to some extent, hypertension. The newly developed questionnaire demonstrates satisfied validity and promising results for extending the ERI model to household and family work.

    Full Text Available Mental health problems (MHP of parents are associated with an increased risk of psychological and developmental difficulties in their children. This study aims at analyzing population-based data of parents with MHP and their children and the effects of associated risk factors in order to further targeted preventive and therapeutic interventions.The BELLA study is the mental health module of the German National Health Interview and Examination Survey among Children and Adolescents. MHP in parents and in their children as well as associated risk factors were examined in a sample of N = 1158 parents with children aged 11 to 17 years.Parental MHP were identified in 18.6% of the sample. Risk factors associated with parental MHP were low SES, parental unemployment, stressful life events, parental daily strain, parental chronic disease, and child MHP. A rate of 19.1% of the children of parents with MHP reported MHP themselves, the corresponding rate among children of parents without MHP was 7.7%. In multiple regression analyses the risk for children of parents with MHP to report MHP themselves was almost two times higher than the risk of children of parents without MHP. Other significant associations with child MHP included gender, the parents' age, and stressful life events.Parental MHP constitute a significant risk for the mental health of their children. Targeted screening methods and preventive interventions are needed.

    Spangenberg, Lena; Zenger, Markus; Glaesmer, Heide; Brähler, Elmar; Strauss, Bernhard


    The present study aimed to extend the knowledge regarding dimensionality, socio-demographic correlates and shifts in age stereotypes over the past 15 years using a time-sequential design. In 1996 and 2011, we assessed age stereotypes in two independent samples of the German population aged ≥ 45 years ( N  = 970 in sample 1, N  = 1545 in sample 2). Three scales with six items each were assessed. Two scales cover negative (i.e., rigidity/isolation, burden), and one scale covers positive age stereotypes (wisdom/experience). Dimensionality of the scale, associations with socio-demographic variables and whether the stereotypes have shifted were tested using confirmatory factor analyses, structural equation modeling and analyses of variances. Three dimensions were identified and replicated following an exploratory as well as a confirmatory approach. Age stereotypes did shift between 1996 and 2011 in the dimension burden (i.e., becoming more negative). Our results further underpin the finding that age stereotypes are multifaceted and suggest that dimensions do not change over time. Additionally, our data provide some evidence that societal age stereotypes partly change over time.

    Svenja eCaspers


    Full Text Available The ongoing 1000 brains study (1000BRAINS is an epidemiological and neuroscientific investigation of structural and functional variability in the human brain during aging. The two recruitment sources are the 10-year follow-up cohort of the German Heinz Nixdorf Recall (HNR Study, and the HNR MultiGeneration Study cohort, which comprises spouses and offspring of HNR subjects. The HNR is a longitudinal epidemiological investigation of cardiovascular risk factors, with a comprehensive collection of clinical, laboratory, socioeconomic, and environmental data from population-based subjects aged 45-75 years on inclusion. HNR subjects underwent detailed assessments in 2000, 2006, and 2011, and completed annual postal questionnaires on health status. 1000BRAINS accesses these HNR data and applies a separate protocol comprising: neuropsychological tests of attention, memory, executive functions & language; examination of motor skills; ratings of personality, life quality, mood & daily activities; analysis of laboratory and genetic data; and state-of-the-art magnetic resonance imaging (MRI, 3 Tesla of the brain. The latter includes (i 3D-T1- and 3D-T2-weighted scans for structural analyses and myelin mapping; (ii three diffusion imaging sequences optimized for diffusion tensor imaging, high-angular resolution diffusion imaging for detailed fibre tracking and for diffusion kurtosis imaging; (iii resting-state and task-based functional MRI; and (iv fluid-attenuated inversion recovery and MR angiography for the detection of vascular lesions and the mapping of white matter lesions. The unique design of 1000BRAINS allows: (i comprehensive investigation of various influences including genetics, environment and health status on variability in brain structure and function during aging; and (ii identification of the impact of selected influencing factors on specific cognitive subsystems and their anatomical correlates.

  3. German Jewish Intellectuals and the German Occupation of Belgium

    Directory of Open Access Journals (Sweden)

    Ulrich Wyrwa


    Full Text Available In August 1914 the majority of German Jews expressed their patriotic approval of the war and their loyalty to the German state. They identified with Germany, and a large number signed up voluntarily for military service at the front. The Jewish population in Germany affirmed the war not least because it was directed against Russia, the harshest adversary of the Jews. This paper concentrates on the first acts of war conducted by the German military forces during the German occupation of Belgium; it examines whether and in what way German-Jewish Intellectuals perceived Germany’s violation of Belgian neutrality and the new feature of war as a war against a civilian population. The first part examines autobiographical sources to reconstruct the experiences and the perception of German Jewish soldiers, German military rabbis, and other German Jewish witnesses to the war. The second part then analyzes the coverage of German Jewish newspapers regarding the warfare against Belgium; and, finally, the third and last part scrutinizes the commentaries of German Jewish intellectuals and socialist Jews [Jewish socialists?] regarding the German war against Belgium.

    Bekes, Katrin; John, Mike T; Zyriax, Rona; Schaller, Hans-Günter; Hirsch, Christian


    The aims of this study were to develop a German version of the Child Perceptions Questionnaire (CPQ11-14, a measure of oral health-related quality of life in 11-14-year-old children) and to assess the instrument's reliability and validity in German children ages 11-14. The English original version of the CPQ11-14 questionnaire was translated into German (CPQ-G11-14) by a forward-backward translation method. Reliability was investigated in 1,061 subjects aged 11-14 years from a regional sample (Wernigerode, Saxonia-Anhalt, Germany) who were recruited during the annual dental public health examination. The subjects completed the CPQ-G11-14 and were clinically examined for the presence of dental caries, plaque accumulation, and malocclusion. In the reliability assessment, questionnaire summary score test-retest reliability was excellent (intraclass correlation coefficient, 95% confidence interval (CI) = 0.83, 0.73-0.94) and internal consistency was satisfactory (Cronbach's alpha, lower limit of CI = 0.87, 0.86). Validity of the CPQ-G11-14 questionnaire was supported by correlations with global ratings of oral health and overall well-being that were moderate in magnitude and met expectations (r = 0.35; 95% CI, 0.30-0.40 and r = 0.30; 95% CI, 0.24-0.35, respectively). In conclusion, the German version of the CPQ11-14 was reliable and valid in a general population of 11-14-year-old German children.

    Killer cell immunoglobulin-like receptors (KIR) are the most polymorphic receptors of natural killer (NK) cells. Their activity diversifies the functions of NK cells in the antiviral immune response, so the presence of certain KIR may affect transmission of HIV-1. The aim of the study was to evaluate the influence of KIR genes on the susceptibility to HIV-1 infection in the Polish population depending on the route of exposure. We determined the frequencies of activating (2DS1, 2DS2, 2DS3, 2DS4f, 2DS4del, 2DS5, 3DS1) and inhibitory (2DL1, 2DL2, 2DL3, 2DL5, 3DL1) KIRs in HIV-1-positive patients (n = 459), individuals exposed to HIV-1 but uninfected (EU, n = 118) and in uninfected, healthy blood donors (BD, n = 98). Analysis was performed using stepwise logistic regression. Apart from KIRs, CCR5-∆32, and CCR2-64I, alleles were also analyzed, as we knew or suspected that these features could affect susceptibility to HIV infection. The regression confirmed the protective effect of CCR5-∆32 (OR = 0.25, p = 0.006) and CCR2-64I (OR = 0.59, p = 0.032) against HIV infection. Among KIR genes, 2DL3 was found to be a protective factor (OR = 0.30, p = 0.015). A similar effect was seen for 3DS1 but only in intravenous drug users (IDUs) (OR = 0.30, p = 0.019), not in sexually exposed people. 2DL5 was found to be a factor facilitating HIV infection (OR = 2.13, p = 0.013). A similar effect was observed for 2DL2 but only in females (OR = 2.15, p = 0.040), and 2DS1 in IDUs (OR = 3.03, p = 0.022). Our results suggest a beneficial role of KIR3DS1 and 2DL3 supporting resistance to HIV infection and a harmful effect of 2DS1, 2DL5, and 2DL2 genes promoting HIV acquisition.

  6. Reliability and validity of the Beck Depression Inventory-Fast Screen for medical patients in the general German population. (United States)

    Kliem, Sören; Mößle, Thomas; Zenger, Markus; Brähler, Elmar


    The Beck Depression Inventory Fast Screen (BDI-FS) is a self-report instrument for the detection of depression in youths and adults. It measures the severity of the depression, corresponding to the non-somatic criteria for the diagnosis of a major depression according to DSM-5. Until now the psychometric properties of the instrument have not been studied in the general population. In 2012, a survey representative for the Federal Republic of Germany was conducted. In addition to the BDI-FS, further self-rating questionnaires as well as a demographic questionnaire were administered. Altogether, 4480 people were surveyed with a return rate of 56.1% (N=2467 persons). Approximately 53% of those surveyed were women. The average age was 49.4 years (SD=18.0), with a range of 14-91 years. For the BDI-FS total-scores, a coefficient α of .84 was determined (women: α=.83; men: α=.85). In addition, a convergent validity (r=.67) was determined with the Patient Health Questionnaire (PHQ-9). The discriminant validity of the BDI-FS can be classified as satisfactory. Based on a confirmatory factor analysis, the one-dimensionality of the BDI-FS could be confirmed, achieving very good fit indices (total sample: RMSEA=.058, CFI=.990, TLI=.986). An additional invariance analysis regarding gender, different age groups and their interaction resulted in strict invariance for the different multi-group analyses. Studies regarding stability have yet to be undertaken. A standard diagnostic interview for depression was not included. The results support the reliability and validity of the BDI-FS for use with the general German population. Although in the present studies the BDI-FS was superior to the PHQ-9 in terms of its ability to discriminate between depressive and somatic symptoms, in future investigations the diagnostic efficiency of the BDI-FS should be compared with this and other depression inventories (e.g., PHQ-2, PHQ-8, and CES-D).

  7. Quantitative trait loci mapping of calving and conformation traits on Bos taurus autosome 18 in the German Holstein population. (United States)

    Brand, B; Baes, C; Mayer, M; Reinsch, N; Seidenspinner, T; Thaller, G; Kühn, Ch


    Linkage, linkage disequilibrium, and combined linkage and linkage disequilibrium analyses were performed to map quantitative trait loci (QTL) affecting calving and conformation traits on Bos taurus autosome 18 (BTA18) in the German Holstein population. Six paternal half-sib families consisting of a total of 1,054 animals were genotyped on 28 genetic markers in the telomeric region on BTA18 spanning approximately 30 Mb. Calving traits, body type traits, and udder type traits were investigated. Using univariately estimated breeding values, maternal and direct effects on calving ease and stillbirth were analyzed separately for first- and further-parity calvings. The QTL initially identified by separate linkage and linkage disequilibrium analyses could be confirmed by a combined linkage and linkage disequilibrium analysis for udder composite index, udder depth, fore udder attachment, front teat placement, body depth, rump angle, and direct effects on calving ease and stillbirth. Concurrence of QTL peaks and a similar shape of restricted log-likelihood ratio profiles were observed between udder type traits and for body depth and calving traits, respectively. Association analyses were performed for markers flanking the most likely QTL positions by applying a mixed model including a fixed allele effect of the maternally inherited allele and a random polygenic effect. Results indicated that microsatellite marker DIK4234 (located at 53.3 Mb) is associated with maternal effects on stillbirth, direct effects on calving ease, and body depth. A comparison of effects for maternally inherited DIK4234 alleles indicated a favorable, positive correlation of maternal and direct effects on calving. Additionally, the association of maternally inherited DIK4234 marker alleles with body depth implied that conformation traits might provide the functional background of the QTL for calving traits. For udder type traits, the strong coincidence of QTL peaks and the position of the QTL in a

    BACKGROUND: This study examined two main hypotheses: a) Polish immigrants\\' smoking estimates are greater than their Irish counterparts (b) Polish immigrants purchasing cigarettes from Poland smoke "heavier" (>\\/= 20 cigarettes a day) when compared to those purchasing cigarettes from Ireland. The study also set out to identify significant predictors of \\'current\\' smoking (some days and everyday) among the Polish immigrants. METHODS: Dublin residents of Polish origin (n = 1,545) completed a previously validated Polish questionnaire in response to an advertisement in a local Polish lifestyle magazine over 5 weekends (July-August, 2007). The Office of Tobacco Control telephone-based monthly survey data were analyzed for the Irish population in Dublin for the same period (n = 484). RESULTS: Age-sex adjusted smoking estimates were: 47.6% (95% Confidence Interval [CI]: 47.3%; 48.0%) among the Poles and 27.8% (95% CI: 27.2%; 28.4%) among the general Irish population (p < 0.001). Of the 57% of smokers (n = 345\\/606) who purchased cigarettes solely from Poland and the 33% (n = 198\\/606) who purchased only from Ireland, 42.6% (n = 147\\/345) and 41.4% (n = 82\\/198) were "heavy" smokers, respectively (p = 0.79). Employment (Odds Ratio [OR]: 2.89; 95% CI: 1.25-6.69), lower education (OR: 3.76; 95%CI: 2.46-5.74), and a longer stay in Ireland (>24 months) were significant predictors of current smoking among the Poles. An objective validation of the self-reported smoking history of a randomly selected sub-sample immigrant group, using expired carbon monoxide (CO) measurements, showed a highly significant correlation coefficient (r = 0.64) of expired CO levels with the reported number of cigarettes consumed (p < 0.0001). CONCLUSION: Polish immigrants\\' smoking estimates are higher than their Irish counterparts, and particularly if employed, with only primary-level education, and are overseas >2 years.

  9. The Impact of the Russian Civil Judicial Proceedings Act of 1864 on the Polish Civil Proceedings

    Directory of Open Access Journals (Sweden)

    Piotr Rylski


    Full Text Available This paper describes the influence, which had already been exerted, and which is still exerted by the Russian Civil Judicial Proceedings Act of November 20, 1864 (CJPA on the Polish civil proceedings. First, the authors present the history of CJPA’s presence in the Polish territories. Next, they discuss the general significance of this act and its solutions for the process of shaping the Polish civil procedure in the interwar period. Finally, they present selected examples of the regulations and solutions that demonstrate the CJPA’s impact on the Polish civil proceedings. The authors conclude that CJPA exerted a minor impact on the pre-war and present Polish procedural regulations in comparison to the other codes, i.e. the Austrian and German codes. Even today, however, one can find in the Polish Code of Civil Procedure some provisions patterned after the CJPA.

  10. Influences of polymorphic variants of DRD2 and SLC6A3 genes, and their combinations on smoking in Polish population

    Niedoszytko Marek


    Full Text Available Abstract Background Polymorphisms in dopaminergic genes may influence cigarette smoking by their potential impact on dopamine reward pathway function. A1 allele of DRD2 gene is associated with a reduced dopamine D2 receptor density, and it has been hypothesised that A1 carriers are more vulnerable to smoking. In turn, the 9-repeat allele of dopamine transporter gene (SLC6A3 has been associated with a substantial reduction in dopamine transporter, what might result in the higher level of dopamine in the synaptic cleft, and thereby protective role of this allele from smoking. In the present study we investigated whether polymorphic variants of DRD2 and SLC6A3 genes and their combinations are associated with the smoking habit in the Polish population. Methods Genotyping for TaqIA polymorphism of DRD2 and SLC6A3 VNTR polymorphism was performed in 150 ever-smokers and 158 never-smokers. The association between the smoking status and smoking phenotypes (related to the number of cigarettes smoked daily and age of starting regular smoking, and genotype/genotype combinations was expressed by ORs together with 95% CI. Alpha level of 0.05, with Bonferroni correction whenever appropriate, was used for statistical significance. Results At the used alpha levels no association between DRD2 and SLC6A3 genotypes and smoking status was found. However, A1 allele carriers reported longer abstinence periods on quitting attempts than non-carriers (p = 0.049. The ORs for heavier smoking were 0.38 (0.17-0.88, p = 0.023, and 0.39 (0.17-0.88, p = 0.021 in carriers compared to non-carriers of A1 or *9 allele, respectively, and the OR for this smoking phenotype was 8.68 (2.47-30.46, p = 0.0005 for the A1-/9- genotype combination, relatively to the A1+/9+. Carriers of *9 allele of SLC6A3 had over twice a lower risk to start smoking before the age of 20 years compared to non-carriers (sex-adjusted OR = 0.44; 95% CI: 0.22-0.89; p = 0.0017, and subjects with A1-/9- genotype

  11. Functional Median Polish

    KAUST Repository

    Sun, Ying


    This article proposes functional median polish, an extension of univariate median polish, for one-way and two-way functional analysis of variance (ANOVA). The functional median polish estimates the functional grand effect and functional main factor effects based on functional medians in an additive functional ANOVA model assuming no interaction among factors. A functional rank test is used to assess whether the functional main factor effects are significant. The robustness of the functional median polish is demonstrated by comparing its performance with the traditional functional ANOVA fitted by means under different outlier models in simulation studies. The functional median polish is illustrated on various applications in climate science, including one-way and two-way ANOVA when functional data are either curves or images. Specifically, Canadian temperature data, U. S. precipitation observations and outputs of global and regional climate models are considered, which can facilitate the research on the close link between local climate and the occurrence or severity of some diseases and other threats to human health. © 2012 International Biometric Society.

  13. [Is health really the most important value? - Results of a representative survey of the German general population concerning the subjective meaning of health]. (United States)

    Hinz, A; Hübscher, U; Brähler, E; Berth, H


    The aim of this study was to investigate which meaning is attributed to health by the general population. Furthermore, the relationship between health satisfaction and health importance was also analysed. A sample of 4,808 representatively selected subjects from the general German population judged the importance and the satisfaction with several life domains, including health, using the questions on life satisfaction FLZ (M). Moreover, sociodemographic variables (sex, age, socioeconomic status) and psychological variables (self-esteem, resilience, anxiety and depression) were collected. Health is the most important life domain. The importance of health increases with increasing age. However, there are no sex differences and SES (socio-economic status) differences concerning the importance of health. Subjective satisfaction with health and health importance are only marginally correlated (r=0.08). High degrees of self-esteem and resilience are associated with a high importance of health. Anxiety and depression show only weak relationships to the importance of health. In the German general population health has a very high subjective significance. This is not only true for handicapped or ill people, but for all subsamples of the society. Therefore, a general plea for an understanding of the importance of health is not necessary, not even for subgroups. Preventive activity can be based on the general understanding of the meaning of health, but it should pursue specific health- related goals for target groups. © Georg Thieme Verlag KG Stuttgart · New York.

    The purpose of the present project was to characterise the pollutant freight of suspended matter and suspended-matter-borne sediments in the Oder river system on the basis of large samples drawn at selected sampling sites. One of the major goals was to assess and draw up a balance of the transport regime of suspended matter between the compartments water, suspended matter and sediments. Special attention was given to the composition and structure of suspended matter as well as to the distribution of trace elements in the various components. Furthermore, the study was intended to provide ecology-related information on the basis of selected biogenic components. Statements on the time course of pollution of estuarine waters and the Baltic Sea by way of the Oder can be derived from a characterisation of current fluviatile solids (suspended matter and suspended-matter-borne sediments) and determination of their quantitative proportions. The following research strategy was derived from these goals: for a characterisation of suspended matter in terms of composition, structure and biogenic origin it is necessary to determine the concentration of suspended matter, its granulometric composition, carbon and sulphur content, biogenic opal content, mineral content, phase composition, metal content, structure of suspended flakes and association of diatoms in the suspended flakes and on the periphyton. [German] Das Vorhaben ist darauf ausgerichtet, den Belastungszustand der Schwebstoffe und schwebstoffbuertigen Sedimente im Oderflusssystem anhand von Grossproben ausgewaehlter Probenahmeorte zu charakterisieren. Ein wesentliches Ziel ist die Beurteilung des Transportregimes der Schwebstoffe zwischen den Kompartimenten Wasser, Schwebstoff und Sediment sowie seine Bilanzierung. Dabei gilt die besondere Aufmerksamkeit der Zusammensetzung und der Struktur der Schwebstoffe sowie die Spurenelementspeziation an die unterschiedlichen Bestandteile.

  15. Probabilistic dietary risk assessment of pesticide residues in foods for the German population based on food monitoring data from 2009 to 2014. (United States)

    Sieke, Christian; Michalski, Britta; Kuhl, Thomas


    Dietary risks for the German population owing to pesticide residues in foods were assessed based on food monitoring data, consumption surveys for children and adults and compound specific toxicological reference values or general thresholds of toxicological concern. A tiered probabilistic modelling was conducted to screen 700 pesticides for significant long- and short-term dietary exposures. Especially for the short-term dietary exposure, the probabilistic methodology used allows simultaneous consideration of the complete daily consumption, whereas most regulatory bodies still rely on single commodity approaches. After screening, refined exposure assessments were conducted for 19 compounds under consideration of conversion factors for toxicologically relevant metabolites, processing information, experimentally derived variability factors and the edible portion for each food item. In total, for 693 compounds the dietary exposure was unlikely to present a chronic or acute public health concern for the German population. In contrast, the refined assessments indicate that the short-term dietary exposure for chlorpyrifos and the cumulative short-term dietary exposure for dimethoate and omethoate may present a public health concern. For copper, owing to exposure assessment limitations, as well as for dimethylvinphos, halfenprox and tricyclazole, which exceeded the thresholds of toxicological concern, the dietary risk assessment remained inconclusive.

The aim of this study is to replicate existing Canadian thresholds of probable low-risk gambling (Currie et al., 2006) in a representative dataset of German gambling behavior (Pathological Gambling and Epidemiology [PAGE]; N = 15,023). Receiver-operating characteristic curves applied in a training dataset (60%) extracted robust thresholds of low-risk gambling across 4 nonexclusive definitions of gambling problems (1 + to 4 + Diagnostic and Statistical Manual for Mental Disorders-Fifth Edition [DSM-5] Composite International Diagnostic Interview [CIDI] symptoms), different indicators of gambling involvement (across all game types; form-specific) and different timeframes (lifetime; last year). Logistic regressions applied in a test dataset (40%) to cross-validate the heuristics of probable low-risk gambling incorporated confounding covariates (age, gender, education, migration, and unemployment) and confirmed the strong concurrent validity of the thresholds. Moreover, it was possible to establish robust form-specific thresholds of low-risk gambling (only for gaming machines and poker). Possible implications for early detection of problem gamblers in offline or online environments are discussed. Results substantiate international knowledge about problem gambling prevention and contribute to a German discussion about empirically based guidelines of low-risk gambling.

  17. Assessment of Polish population exposure to lead and cadmium with special emphasis to the Katowice Province on the basis of metal concentrations in environmental compartments. (United States)

    Gzyl, J


    Polish data of lead and cadmium concentrations in such environmental compartments as: air, dust, soil, diet and drinking water were presented in the paper. Special emphasis was placed to the Upper Silesian industrial Region, the central part of the Katowice Province, the most polluted area in Poland. An attempt was made to assess human exposure to heavy metals. According to the available data it can be concluded that the WHO tolerable intake (ADI, PTWI) could be exceeded in an extremely disadvantageous situation occurring in the Katowice Province. Furthermore, a critical review of heavy metal standards in soil, dustfall and edible plants, obligatory in Poland, was presented. The author states that there are still some inconsistencies in current regulations in Poland. In order to remove them, an interdisciplinary board consisting of such disciplines representatives as: medicine, toxicology, nutritional science, law and protection of soils used for agricultural purposes should be appointed.

  18. Sexual activity of Polish adults. (United States)

    Pastwa-Wojciechowska, Beata; Izdebski, Zbigniew


    The purpose of this research was to explore the subject of sexual activity in the Polish population, with special focus on age and gender differences, and sexual infidelity. Sexual activity is one of the basic factors in initiating and maintaining relationships. On the one hand, sexual activity enables us to meet natural needs and maintain an intimate relationship with another human being; on the other, it may allow us to overcome loneliness and social isolation by providing the opportunity to express feelings of closeness and unity. The research was conducted on a representative group of 3,200 Poles aged between 15-49, with the support of a well-known Polish research company - TNS OBOP. Face-to-face and Pencil and Paper (PAPI) interviews were carried out. The results focus on two main issues: the age and motives of sexual initiation among teenagers (with a significant percentage starting their sexual activity at the age of 15), and the quality of the sexual lives of adults (average number of sexual partners, sexual infidelity and sexual satisfaction). There is dependence between the type of relationship and the performance or non-performance of sexual activity, as well as the quality of the relationship. Among both adolescents and adults, remaining in a stable relationship (partnership or marriage) promotes loyalty. The performance of sexual goals turns out to be an important mechanism regulating the interpersonal aspects of a relationship, influencing their perception and evaluation.

  20. Comparison of three different fetometric formulas of ICC and BP for calculating the parturition date in a population of German Shepherd. (United States)

    Socha, Piotr; Janowski, Tomasz


    The aim of this study was to evaluate the suitability of three different formulas to predict the parturition date in German Shepherds, using the ultrasonographic fetometry method involving inner chorionic cavity diameter (ICC) and biparietal diameter (BP) measurements in the same population of a single breed. Overall, 53 ICC and 42 BP measurements were taken on 34 bitches. The measured values were substituted into breed-specific formulas for the German Shepherd as well as non-specific formulas for medium-sized bitches. Comparisons of clinical accuracy and statistical analyses of regression lines were performed to test the compatibility of the formulas used. We confirmed the similarity of our clinical results to outcomes obtained using the one breed-specific (Groppetti et al. 2015) and non-specific fetometry models (Luvoni and Grioni 2000), whereas another breed-specific formula (Milani et al. 2013) showed rather low accuracy. Comparing the clinical accuracy of the three formulas, the authors demonstrated that the Luvoni and Grioni (2000) formula for ICC dedicated to medium-sized dogs can also be effectively used in the German Shepherd, even with better results than breed-specific formulas by Groppetti et al. (2015). By contrast, the evaluation of BP formulas proves the successful usage of the Groppetti et al. (2015) formula to determine the date of birth by measuring scull bone structures (p < 0.05). The statistical analysis of regression lines were in agreement with the clinical results and confirmed the higher predictability of Groppetti et al. (2015) and Luvoni and Grioni (2000) formulas, than those of Milani et al. (2013). Copyright © 2017 Elsevier Inc. All rights reserved.

  1. Reference values for placental growth factor (PlGF) concentration and uterine artery doppler pulsatility index (PI) at 11-13(+6) weeks of gestation in the Polish population. (United States)

    The aim of the study was to determine placental growth factor (PIGF) concentration and uterine artery (UtA) Doppler pulsatility index (PI) at 11-13(+6) weeks of gestation in the Polish population. A prospective study was performed in pregnant women who underwent routine ultrasound scan at 11-13(+6) weeks of gestation. All participants completed a questionnaire about their medical history demographics and current pregnancy. Mean arterial pressure (MAP) was calculated. Gestational age was confirmed by CRL and mean UtA PI was calculated. Blood samples were taken to measure beta HCG, PAPP-A and P/GF concentrations. Out of the 577 analyzed participants, 60 (10.4%) were found to have abnormal placentation disorders (20 -hypertensive disorders and 40-IUGR). The patients were subdivided into two groups, depending on pregnancy outcome: unaffected (n = 517) and affected (n = 60). The study did not confirm the anticipated correlation between maternal BMI and PIGF, but the concentration of PIGF was significantly increased in smokers. UtA PI values were not statistically significantly different depending on maternal age, BMI, method of conception, smoking or parity The study confirms that both, UtA PI and PIGF concentrations are CRL-dependent. Median MoM values for PIGF and UtA PI were obtained for each set of CRL measurements. Median PIGF MoM was decreased in pregnancies complicated by hypertensive disorders and IUGR as compared to the unaffected group. The established reference ranges for UtA PI and PIGF at 11-13(+6) weeks of gestation may be of clinical value in predicting placenta-associated diseases in early stages of pregnancy in the Polish population.

    Full Text Available Amount of information transferred by computers grows very rapidly thus outgrowing the average man's capability of reception. It implies computer programs increase in the demand for which would be able to perform an introductory classitication or even selection of information directed to a particular receiver. Due to the complexity of the problem, we restricted it to understanding short newspaper notes. Among many conceptions formulated so far, the conceptual dependency worked out by Roger Schank has been chosen. It is a formal language of description of the semantics of pronouncement integrated with a text understanding algorithm. Substantial part of each text transformation system is a semantic parser of the Polish language. It is a module, which as the first and the only one has an access to the text in the Polish language. lt plays the role of an element, which finds relations between words of the Polish language and the formal registration. It translates sentences written in the language used by people into the language theory. The presented structure of knowledge units and the shape of understanding process algorithms are universal by virtue of the theory. On the other hand the defined knowledge units and the rules used in the algorithms ure only examples because they are constructed in order to understand short newspaper notes.

    Full Text Available The purpose of this study was to determine sexual functioning of Polish athletes with disabilities (including paralympians. The study encompassed 218 people with physical disabilities, aged between 18 and 45 (149 men and 69 women. The entire research population was divided into three groups: Polish paralympians (n = 45, athletes with disabilities (n = 126 and non-athletes with disabilities (n = 47. The quality of sexual life of Polish paralympians was measured by using the Polish version of Female Sexual Function Index and International Index of Erectile Function. Clinically significant erectile dysfunctions were most often diagnosed in non-athletes (83.33% with 50% result of severe erectile dysfunctions, followed by athletes and paralympians with comparable results of 56.98% and 54.17% respectively (p = 0.00388. Statistically significant clinical sexual dysfunctions concerned lubrication, orgasm as well as pain domains, and prevailed among female non-athletes (68.42%, 68.42% and 57.89%. Practising sports at the highest level has a favourable effect on the sexuality of men and women with physical disabilities. Men with physical disabilities manifest more sexual disorders than women, an aspect which should be considered by health-care professionals working with people with disabilities.

    Full Text Available Gilles de la Tourette syndrome (GTS is a neurodevelopmental disorder characterized by motor and vocal tics. Hyperactivity of dopaminergic transmission is considered a prime abnormality in the pathophysiology of tics. There are reciprocal antagonistic interactions between adenosine and dopamine transmission. The aim of the study was to analyze the association of two polymorphisms, rs2228079 in ADORA1 and rs5751876 in ADORA2A, with the risk of GTS and co-morbid disorders.A total of 162 Polish GTS patients and 270 healthy persons were enrolled in the study. Two polymorphisms were selected on the basis of knowledge of SNPs frequencies in ADORA1 and ADORA2A. Chi-square test was used for allelic and genotypic association studies. Association of genotypes with age of tic onset was analyzed with Mann-Whitney test. Multivariate logistic regression was used to find independent predictors of GTS risk.We found that the risk of GTS was associated with rs2228079 and rs5751876 polymorphisms. The GG+GT genotypes of rs2228079 in ADORA1 were underrepresented in GTS patients (p = 0.011, whereas T allele of rs5751876 in ADORA2A was overrepresented (p = 0.017. The GG genotype of rs2228079 was associated with earlier age of tic onset (p = 0.046. We found also that the minor allele G of rs2228079 was more frequent in GTS patients with depression as compared to the patients without depression (p = 0.015. Also the genotype GG was significantly more frequent in patients with obsessive compulsive disorder/behavior (OCD/OCB, p = 0.021 and depression (p = 0.032, as compared to the patients without these co-morbidities. The minor allele T frequency of rs5751876 was lower in GTS patients with co-morbid attention deficit hyperactivity disorder (p = 0.022, and TT+TC genotypes were less frequent in the non-OCD anxiety disorder group (p = 0.045.ADORA1 and ADORA2A variants are associated with the risk of GTS, co-morbid disorders, and may affect the age of tic onset.

  6. [Lysenkoism in Polish botany]. (United States)

    Köhler, Piotr


    Lysenkoism in Poland was never an autonomous phenomenon. The whole array of reasons for which it appeared in Polish science would require a separate study--here it only needs to be pointed out that the major reasons included terror on the part of the security service, lawlessness, the ubiquitous atmosphere of intimidation and terror, censorship, the diminishing sphere of civil liberties, political show trials, propaganda and denunciations. An important role in facilitating the introduction of Lysenkoism was played also by the reorganization of science after World War Two, the isolation of Polish science from science in the West, as well as the damage it had suffered during the war. At first, Lysenkoism was promoted in Poland by a small group of enthusiastic and uncritical proponents. A overview of the events connected with the ten years of Lysenkoism in Poland (end of 1948--beginning of 1958) shows a two-tier picture of how the 'idea' was propagated. The first tier consisted in the activities of the Association of Marxist Naturalists [Koło Przyrodników-Marksistów], which it engaged in since the end of 1948. The Association was later transformed into a Union of Marxist Naturalists, and this in turn merged, in 1952, with the Copernican Society of Polish Naturalists [Polskie Towarzystwo Przyrodników im. Kopernika]. It was that society which promoted Lysenkoism longest, until the end of 1956. The propaganda and training activities of the circle and the society prepared ground for analogous activities of the newly formed Polish Academy of Science (PAN), which--since its very establishment in 1952--engaged in promoting Lysenkoism through its Second Division. These activities were aimed at naturalists, initially at those who were prominent scientists (eg. the conference at Kuźnice, 1950/1951), and then at those who were only starting their academic career (including national courses in new biology at Dziwnów, 1952, or Kortowo, 1953 and 1955).

    Glaesmer, Heide; Hallensleben, Nina; Forkmann, Thomas; Spangenberg, Lena; Kapusta, Nestor; Teismann, Tobias


    To evaluate the main prediction of the Interpersonal Theory of Suicide (IPTS): 3-way-interaction of perceived burdensomeness (PB), thwarted belongingness (TB), and acquired capability (AC) for the prediction of suicidal behavior in a representative population sample. A total of 2513 participants completed measures of suicidal behavior, TB, PB, acquired capability (AC-FAD), and symptoms of depression and anxiety. The two-way-interaction of TB and PB, and the three-way interaction of TB, PB and AC-FAD predict suicidality. Given the cross-sectional nature of the data, conclusions on causality should be handled carefully. The main prediction of the IPTS has been proven in a general population sample.

    Małgorzata Lipowska


    Full Text Available Background Physical attractiveness plays an important part in one’s social functioning. The interest in one’s own appearance have been documented as widespread among the female population, but over the recent years it is more and more often emphasized that concentrating on body appearance concerns men as well. Franzoi and Shields (1984 created the Body Esteem Scale which allows to qualify the subject’s attitude towards his or her own body. The aim of the study was to create a Polish version of the Body Esteem Scale along with the norms for age and sex clusters. Participants and procedure The normalization sample consisted of 4298 participants: 1865 women aged 16 to 80 (M = 29.92; SD = 12.85 and 2433 men aged 16 to 78 (M = 28.74; SD = 11.50. Education levels among the participants were also controlled for. In order to create a Polish version of the Body Esteem Scale, translation was adopted as the adaptation strategy. Like the original one, the Polish scale comprises 35 items grouped into three gender specific subscales. The subscales for women include Sexual Attractiveness, Weight Concern, and Physical Condition, whereas the body esteem of is examined with regards to Physical Attractiveness, Upper Body Strength, and Physical Condition. Results Reliability of subscales was high both for females (Cronbach’s alpha from 0.80 to 0.89 and males (Cronbach’s alpha from 0.85 to 0.88. The given coefficients of reliability cover the original division into subscales adopted by the authors of BES. Conclusions We confirmed high reliability of the Polish version of the Body Esteem Scale, thus we recommend it as a diagnostic tool. Created norms allowed to refer results obtained in the course of research carried out on people with various disorders (e.g. eating disorders or body dysmorphic disorder with population data for corresponding age brackets.

    Worldwide, the most frequent cause of visual impairment is uncorrected refractive error. This analysis focused on the distribution and associations of refractive, corneal and ocular residual astigmatism. As part of the Gutenberg Health study, a population-based cross-sectional study was conducted in the general population of Germany. A comprehensive ophthalmological examination including refraction, tonometry, and Scheimpflug imaging of the anterior cornea (Pachycam) was performed. In addition to the magnitude and type (with-the-rule, against-the-rule, oblique) of the refractive or corneal astigmatism, we calculated the vector components (J 0 , J 45 ) of both astigmatisms and calculated the ocular residual astigmatism. We performed multiple quantile regression analysis to evaluate the factors associated with refractive, corneal and ocular residual astigmatisms. A total of 13,558 subjects (49% female) with a mean age of 54.0 years (range 35-74 years) were included in this study. The prevalence of refractive astigmatism (>1.0D) was 13.0% in right eyes and 12.0% in left eyes, and 85% of these subjects wore spectacles. The distribution of refractive astigmatism showed a two-peak distribution with high astigmatism for with-the-rule and against-the-rule astigmatism. The associated factors were corneal curvature, age and sex for the different astigmatisms (p prevalence of different astigmatisms within a European population. We confirmed a shift with aging from with-the-rule to against-the-rule astigmatism to refractive and corneal astigmatism. Astigmatism has a large impact on visual perception; more than 85% of people with astigmatism over one diopter wore glasses for distance vision.

  11. The role of polymorphisms in ADAM33, a disintegrin and metalloprotease 33, in childhood asthma and lung function in two German populations

    Directory of Open Access Journals (Sweden)

    Klopp Norman


    Full Text Available Abstract Background ADAM33, the first asthma candidate gene identified by positional cloning, may be associated with childhood asthma, lung function decline and bronchial hyperresponsiveness. However, replication results have been inconclusive in smaller previous study populations probably due to inconsistencies in asthma phenotypes or yet unknown environmental influences. Thus, we tried to further elucidate the role of ADAM33 polymorphisms (SNPs in a genetic analysis of German case control and longitudinal populations. Methods Using MALDI-TOF, ten ADAM33 SNPs were genotyped in 1,872 children from the International Study of Asthma and Allergy in Childhood (ISAAC II in a case control setting and further 824 children from the longitudinal cohort Multicentre Study of Allergy (MAS. In both populations the effects of single SNPs and haplotypes were studied and a gene environment analysis with passive smoke exposure was performed using SAS/Genetics. Results No single SNP showed a significant association with doctor's diagnosis of asthma. A trend for somewhat more profound effects of ADAM33 SNPs was observed in individuals with asthma and BHR. Haplotype analyses suggested a minor effect of the ADAM33 haplotype H4 on asthma (p = 0.033 but not on BHR. Associations with non atopic asthma and baseline lung function were identified but no interaction with passive smoke exposure could be detected. Conclusion The originally reported association between ADAM33 polymorphisms and asthma and BHR could not be confirmed. However, our data may suggest a complex role of ADAM33 polymorphisms in asthma ethiology, especially in non atopic asthma.

  12. The use of complementary alternative medicine (CAM) in 1 001 German adults: results of a population-based telephone survey. (United States)

    Bücker, B; Groenewold, M; Schoefer, Y; Schäfer, T


    The objective of this study was to evaluate the patterns of use of complementary alternative medicine (CAM) in a representative adult population in Germany. A population-based telephone survey was conducted in Lübeck, Germany. We performed computer-assisted telephone interviews (CATI) in order to obtain information on demographics, health status, prevalence of CAM usage, motivation for using CAM, type of CAM and health problems for which CAM were used. 1,001 adults (median age 48 years) participated in the study (response 46.8%). 79.6% of the interviewed subjects reported health problems. The most frequently named problems were chronic pain (45.3%), circulation problems (32.9%) and colds with fever (27.8%). Non-users of CAM had a lower incidence (76.6%) of overall illness than users (83.5%) (OR 0.65, 0.47-0.89). 42.3% of the participants had used CAM. The CAM user group consisted of significantly more females (72.8 vs. 55.5%) (OR 2.32, 1.74-3.08) and involved better educated subjects (school education >12 years, 36.6 vs. 27.9%, OR 3.25, 1.35-7.81) than the non-user group. The main health problems for which CAM was used were chronic pain (36.3%), some cases of uncomplicated colds (16.9%) and for improving general health (14.7%). Three procedures accounted for the majority of usage: Acupuncture (34.5%), homeopathy (27.3%) and herbal medicine (9.7%). A large number of participants reported as the main reason for using CAM the wish to avoid drugs as much as possible (31.7%). 26.7% reported opting for CAM due to the recommendation of their physician. 23.9% gave unsatisfactory results of conventional medicine as reason for CAM usage. CAM is used widely for different complaints by the general population. This frequent use of CAM has implications for the health-care system and health policy.

    Maske, Ulrike E; Riedel-Heller, Steffi G; Seiffert, Ingeburg; Jacobi, Frank; Hapke, Ulfert


    Objective: To determine the prevalence and comorbid mental disorders of self-reported diagnosis of burnout syndrome in the general population of Germany. Methods: In the German Health Interview and Examination Survey (DEGS1) self-reported diagnosis of a burnout syndrome made by a physician or psychotherapist was assessed in a standardized interview (N = 7987). For N = 4483 mental disorders were determined with the Composite International Diagnostic Interview (CIDI). Weighted lifetime and 12-month prevalences were calculated. Results: Lifetime prevalence of diagnosed burnout syndrome was 4.2 % (women 5.2 %, men 3.3 %), 12-month prevalence was 1.5 % (women 1.9 %, men 1.1 %). Highest prevalences were found in 40 - 59 year olds, in people with middle and high socio-economic status and in women with low and men with high social support. Among the 12-month cases, 70.9 % had at least one DSM-IV disorder. Associations were found for the diagnosis of burnout syndrome with somatoform, affective and anxiety disorders. Conclusion: The diagnosis of burnout syndrome is less frequently given and reported than expected. People with a burnout diagnosis often have a manifest mental disorder. © Georg Thieme Verlag KG Stuttgart · New York.

  14. [Frequency and distribution of sleep problems and insomnia in the adult population in Germany: results of the German Health Interview and Examination Survey for Adults (DEGS1)]. (United States)

    Schlack, R; Hapke, U; Maske, U; Busch, M; Cohrs, S


    Sleep disturbances are associated with a variety of physical and mental health disorders and cause high direct and indirect economic costs. The aim of this study was to report the frequency and distribution of problems of sleep onset and maintaining sleep, sleep quality, effective sleep time, and the consumption of sleeping pills in the adult population in Germany. During the 4 weeks prior to the interview, about one third of the respondents reported potentially clinically relevant problems initiating or maintaining sleep; about one-fifth reported poor quality of sleep. When additionally considering impairments during the daytime such as daytime fatigue or exhaustion, a prevalence of 5.7 % for an insomnia syndrome was found. Women were twice as likely to be affected by insomnia-syndrome as men. Significant age differences were not seen. Persons with low socioeconomic status had an increased risk of insomnia (OR: 3.44) as did people residing in West Germany (OR: 1.53). Women with low socioeconomic status (OR: 4.12) and West German men (OR: 1.79) were more affected. The results illustrate the considerable public health relevance of insomnia-related sleep disturbances. An English full-text version of this article is available at SpringerLink as supplemental.

  15. The population size, demography and the harvest strategy for the red deer (Cervus elaphus L. in the Polish eastern Carpathians

    Directory of Open Access Journals (Sweden)

    Merta, D.


    Full Text Available Using a line intercept snow track index, the population density and numbers of red deer (Cervus elaphusL. in 8 Forest Districts (Baligród, Cisna, Dukla, Lutowiska, Komacza, Stuposiany, Rymanów and Wetlina were estimated during February 2000. The total number of red deer inhabiting the study area (134.0 thousand hectares of forest was 4,081 individuals. The average population density was 30.4 red deer/1000 ha and it ranged from 10.1 animals/1000 ha in Wetlina Forest District to 39.3 individuals/1000 ha in Dukla Forest District. In September 2000, observation records of 952 red deer indicated that male/female ratio was 1:1.6, and the calf/female index was 31 calves per 100 females. Using a population dynamics model, an annual population recruitment rate was calculated. It ranged from 10.5% to 18.1% of the population size in March and it was negatively correlated with the population density of wolves. A computer simulation of various harvest strategies showed that the low percentage of old stags in the present red deer population was caused by over-harvest of 2-5-year-old stags. Therefore, it is suggested that the percentage of young males in the hunting bag should not be higher than 30% of the total harvested males.

The overpopulation problem was noted, and henceforth the the exceeding quantity of euthanized and dead cases. Another pro...

  17. Strong or Weak Handgrip? Normative Reference Values for the German Population across the Life Course Stratified by Sex, Age, and Body Height.

    Directory of Open Access Journals (Sweden)

    Nadia Steiber

    Full Text Available Handgrip strength is an important biomarker of healthy ageing and a powerful predictor of future morbidity and mortality both in younger and older populations. Therefore, the measurement of handgrip strength is increasingly used as a simple but efficient screening tool for health vulnerability. This study presents normative reference values for handgrip strength in Germany for use in research and clinical practice. It is the first study to provide normative data across the life course that is stratified by sex, age, and body height. The study used a nationally representative sample of test participants ages 17-90. It was based on pooled data from five waves of the German Socio-Economic Panel (2006-2014 and involved a total of 11,790 persons living in Germany (providing 25,285 observations. Handgrip strength was measured with a Smedley dynamometer. Results showed that peak mean values of handgrip strength are reached in men's and women's 30s and 40s after which handgrip strength declines in linear fashion with age. Following published recommendations, the study used a cut-off at 2 SD below the sex-specific peak mean value across the life course to define a 'weak grip'. Less than 10% of women and men aged 65-69 were classified as weak according to this definition, shares increasing to about half of the population aged 80-90. Based on survival analysis that linked handgrip strength to a relevant outcome, however, a 'critically weak grip' that warrants further examination was estimated to commence already at 1 SD below the group-specific mean value.

    Full Text Available Diets rich in fruits and vegetables, like the Dietary Approaches to Stop Hypertension (DASH-diet, are usually characterized by high potassium intake and reduced dietary acid load, and have been shown to reduce blood pressure (BP. However, the relevance of potential renal acid load (PRAL for BP has not been compared with the relevance to BP of urinary biomarker (K-urine- and dietary food frequency questionnaire (K-FFQ-based estimates of potassium intake in a general adult population sample. For 6788 participants (aged 18–79 years of the representative German Health-Interview and Examination Survey for Adults (DEGS1, associations of PRAL, K-urine, and K-FFQ with BP and hypertension prevalence were cross-sectionally examined in multivariable linear and logistic regression models. PRAL was significantly associated with higher systolic BP (p = 0.0002 and higher hypertension prevalence (Odds ratio [OR] high vs. low PRAL = 1.45, p = 0.0004 in models adjusted for age, sex, body mass index (BMI, estimated sodium intake, kidney function, relevant medication, and further important covariates. Higher estimates of K-FFQ and K-urine were related to lower systolic BP (p = 0.04 and p < 0.0001 and lower hypertension prevalence (OR = 0.82, p = 0.04 and OR = 0.77, p = 0.02 as well as a lower diastolic BP (p = 0.03 and p = 0.0003. Our results show, for the first time in a comparative analysis of a large representative population sample, significant relationships of BP and hypertension prevalence with questionnaire- and biomarker-based estimates of potassium intake and with an estimate of dietary acid load.

  19. Tooth polishing: The current status

    Directory of Open Access Journals (Sweden)

    Madhuri Alankar Sawai


    Full Text Available Healthy teeth and gums make a person feel confident and fit. As people go about their daily routines and with different eating and drinking habits, the tooth enamel turns yellowish or gets stained. Polishing traditionally has been associated with the prophylaxis procedure in most dental practices, which patients know and expect. However, with overzealous use of polishing procedure, there is wearing of the superficial tooth structure. This would lead to more accumulation of local deposits. Also, it takes a long time for the formation of the fluoride-rich layer of the tooth again. Hence, now-a-days, polishing is not advised as a part of routine oral prophylaxis procedure but is done selectively based on the patients′ need. The article here, gives an insight on the different aspects of the polishing process along with the different methods and agents used for the same.

  20. Lysenko affair and Polish botany. (United States)

    Köhler, Piotr


    This article describes the slight impact of Lysenkoism upon Polish botany. I begin with an account of the development of plant genetics in Poland, as well as the attitude of scientists and the Polish intelligentsia toward Marxist philosophy prior to the World War II. Next I provide a short history of the introduction and demise of Lysenkoism in Polish science, with a focus on events in botany, in context with key events in Polish science from 1939 to 1958. The article outlines the little effects of Lysenkoism upon botanists and their research, as well as how botanists for the most part rejected what was often termed the "new biology." My paper shows that though Lysenko's theories received political support, and were actively promoted by a small circle of scientists and Communist party activists, they were never accepted by most botanists. Once the political climate in Poland altered after the events of 1956, Lysenko's theories were immediately abandoned.

  1. Primary care emergency services utilization in German-speaking Switzerland: a population-based cross-sectional study. (United States)

    Güntensperger, Urs; Pinzello-Hürlimann, Rosmarie; Martina, Benedict; Ciurea, Annette; Muff, Brigitte; Gutzwiller, Jean-Pierre


    Traditionally, emergency consultations have been done by a general practitioner (GP) in Switzerland. Over the last years, there seems to have been a shift between general practice to hospital emergency ward utilisation. There are several local initiatives of general practitioners and hospitals to change the organisation of emergency care. To plan a new organisation form of emergency care, delivery should be based on population based data. The aim of the study was to investigate the epidemiology and distribution of emergency consultations of primary care in a hospital and in a practice of general practitioners. In addition, factors of clinical performance in emergency consultations are of great public health interest. For this survey, all emergency patient contacts of general practitioners from the catchment area of Bülach, serving 27 088 inhabitants, were assessed by a questionnaire during the fourth quarter of 2006. Sex, age, time, duration of the contact and triage diagnosis were assessed. In addition, all patients seen by the emergency ward at the local hospital were assessed. Contact rates and hospitalisation rates per 100 000 inhabitants were determined. In addition, a multiple linear regression model was performed to determine factors associated with consultation time as a marker for clinical performance. Between October 1th and December 31th 2006, 1001 patient contacts were registered at the same time period in the hospital and general practice. The patient contact rate was 94.8 contacts per 100 000 inhabitants per day, and the hospitalisation rate was 9.1 patient per 100 000 inhabitants. Patients seen at the hospital were older than in general practice (41.2 ± 22.8 vs. 32.6 ± 26.3 years) and consultation and waiting time was longer in the hospital than consultation time with the GP (144.8 ± 106.5 vs. 19.6 ± 17.6 minutes). Nearly 1 out of 1000 inhabitants were looking for emergency primary care help, and 10% of the patients were seen urgently by general

  2. Elastic emission polishing

    Energy Technology Data Exchange (ETDEWEB)

    Loewenthal, M.; Loseke, K.; Dow, T.A.; Scattergood, R.O.


    Elastic emission polishing, also called elastic emission machining (EEM), is a process where a stream of abrasive slurry is used to remove material from a substrate and produce damage free surfaces with controlled surface form. It is a noncontacting method utilizing a thick elasto-hydrodynamic film formed between a soft rotating ball and the workpiece to control the flow of the abrasive. An apparatus was built in the Center, which consists of a stationary spindle, a two-axis table for the workpiece, and a pump to circulate the working fluid. The process is controlled by a programmable computer numerical controller (CNC), which presently can operate the spindle speed and movement of the workpiece in one axis only. This apparatus has been used to determine material removal rates on different material samples as a function of time, utilizing zirconium oxide (ZrO{sub 2}) particles suspended in distilled water as the working fluid. By continuing a study of removal rates the process should become predictable, and thus create a new, effective, yet simple tool for ultra-precision mechanical machining of surfaces.

    Full Text Available Twenty-six years ago the international community witnessed one of the most dramatic changes in economic systems. Naturally, the fall of communism in Eastern Europe and its consequences were events difficult to judge and anticipate in their immediate aftermath. Today, we have gained a much more coherent perspective on their meaning. The political liberalization of Poland in 1989 and its transition to the market economy was generally perceived as the most successful of all post-communist countries. From 1990 to 2013, Poland experienced the most outstanding economic growth within the former communist bloc. It doubled its GDP in real terms and became the only country to experience economic growth during the financial crisis of 2008-09. However, the polish secret recipe lies in the "shock therapy" adopted at the beginning of the 90's. The aim of this paper is to examine the importance of the Balcerowicz's program in creating the basis for economic stability and growth through privatization, liberalization of foreign trade, monetary reform and an open economy. We will also review the impact of this unprecedented transformation in shaping a strong, market-oriented economy.

  4. Long-term oncologic outcomes after laparoscopic vs. open colon cancer resection: a high-quality population-based analysis in a Southern German district. (United States)

    Völkel, Vinzenz; Draeger, Teresa; Gerken, Michael; Klinkhammer-Schalke, Monika; Fürst, Alois


    Over 20 years after the introduction of laparoscopic surgery for colon cancer, many surgeons still prefer the open approach. Whereas randomized controlled trials (RCTs) have proven the oncologic safety of laparoscopy, long-term data depicting daily clinical routine are scarce. This population-based cohort study compares 5-year overall, relative, and recurrence-free survival rates after laparoscopic and open colon carcinoma surgery. Data derive from an independent German cancer registry encompassing all tumor patients within a political district of 1.1 million inhabitants. The final analysis included 2669 patients with major elective resection of primary non-metastatic colonic adenocarcinoma between January 1, 2004 and December 31, 2013. Survival rates were compared using Kaplan-Meier analyses, relative survival models, and multivariate Cox regression. Sensitivity analysis quantified selection bias. The proportion of laparoscopic procedures increased from 9.7 to 25.8% in 2011 and dropped again to 15.8% at the end of observation period. Laparoscopy patients were younger, had a lower tumor stage, and were more likely to receive postoperative chemotherapy. Overall, relative, and recurrence-free survival was significantly superior or equivalent in Kaplan-Meier analysis (5-year overall survival rate open vs. laparoscopic: 69.0 vs. 80.2%, p < 0.001). The superiority of laparoscopy mostly remained stable after adjusting for confounders, although significance was only reached in T1-3 patients without lymph node metastases (overall survival: hazard ratio (HR) 0.654; 95% confidence interval (CI) 0.446-0.958; p = 0.029). Laparoscopy is a safe and promising alternative to the open approach in daily clinic practice. These favorable outcomes require future confirmation by high-quality studies outside the setting of RTCs.

  6. Polish Toxic Currency Options

    Directory of Open Access Journals (Sweden)

    Waldemar Gontarski


    Full Text Available Toxic currency options are defined on the basis of the opposition to the nature (essence of an option contract, which is justified in terms of norms founded on the general law clause of characteristics (nature of a relation (which represents an independent premise for imposing restrictions on the freedom of contracts. So-understood toxic currency options are unlawful. Indeed they contravene iuris cogentis regulations. These include for instance option contracts, which are concluded with a bank, if the bank has not informed about option risk before concluding the contract; or the barrier options, which focus only on the protection of banks interests. Therefore, such options may appear to be invalid. Therefore, performing contracts for toxic currency options may be qualified as a criminal mismanagement. For the sake of security, the manager should then take into consideration filing a claim for stating invalidity (which can be made in a court verdict. At the same time, if the supervisory board member in a commercial company, who can also be a subject to mismanagement offences, commits an omission involving lack of reaction (for example, if he/she fails to notify of the suspected offence committed by the management board members acting to the companys detriment when the management board makes the company conclude option contracts which are charged with absolute invalidity the supervisory board member so acting may be considered to act to the companys detriment. In the most recent Polish jurisprudence and judicature the standard of a good host is treated to be the last resort for determining whether the managers powers resulting from criminal regulations were performed. The manager of the exporter should not, as a rule, issue any options. Issuing options always means assuming an obligation. In the case of currency put options it is an absolute obligation to purchase a given amount in euro at exchange rate set in advance. On the other hand issuing

    Schizophrenia has been associated with a large range of autoimmune diseases, with a history of any autoimmune disease being associated with a 45% increase in risk for the illness. The inflammatory system may trigger or modulate the course of schizophrenia through complex mechanisms influencing neurodevelopment, neuroplasticity and neurotransmission. In particular, increases or imbalance in cytokine before birth or during the early stages of life may affect neurodevelopment and produce vulnerability to the disease. A total of 27 polymorphisms of IL1N gene: rs1800587, rs17561; IL1B gene: rs1143634, rs1143643, rs16944, rs4848306, rs1143623, rs1143633, rs1143627; IL1RN gene: rs419598, rs315952, rs9005, rs4251961; IL6 gene: rs1800795, rs1800797; IL6R gene: rs4537545, rs4845617, rs2228145, IL10 gene: rs1800896, rs1800871, rs1800872, rs1800890, rs6676671; IL10RA gene: rs2229113, rs3135932; TGF1B gene: rs1800469, rs1800470; each selected on the basis of molecular evidence for functionality, were investigated in this study. Analysis was performed on a group of 621 patients with diagnosis of schizophrenia and 531 healthy controls in Polish population. An association of rs4848306 in IL1B gene, rs4251961 in IL1RN gene, rs2228145 and rs4537545 in IL6R with schizophrenia have been observed. rs6676671 in IL10 was associated with early age of onset. Strong linkage disequilibrium was observed between analyzed polymorphisms in each gene, except of IL10RA. We observed that haplotypes composed of rs4537545 and rs2228145 in IL6R gene were associated with schizophrenia. Analyses with family history of schizophrenia, other psychiatric disorders and alcohol abuse/dependence did not show any positive findings. Further studies on larger groups along with correlation with circulating protein levels are needed. Copyright © 2015 Elsevier B.V. All rights reserved.

  8. Efficient polishing of aspheric optics

    Energy Technology Data Exchange (ETDEWEB)

    Taylor, J.S.; Piscotty, M.A.; Nguyen, N.Q.; Landram, C.S.; Ng, L.C.


    The objectives of this project are to develop, evaluate, and optimize novel designs for a polishing tool intended for ultra-precise figure corrections on aspheric optics with tolerances typical of those required for use in extreme ultraviolet (EUV) projection lithography. This work may lead to an enhanced US industrial capability for producing optics for EUV, x-ray and, other high precision applications. LLNL benefits from developments in computer-controlled polishing and the insertion of fluid mechanics modeling into the precision manufacturing area. Our accomplishments include the numerical estimation of the hydrodynamic shear stress distribution for a new polishing tool that directs and controls the interaction of an abrasive slurry with an optical surface. A key milestone is in establishing a correlation between the shear stress predicted using our fluid mechanics model and the observed removal footprint created by a prototype tool. In addition, we demonstrate the ability to remove 25 nm layers of optical glass in a manner qualitatively similar to macroscopic milling operations using a numerically- controlled machine tool. Other accomplishments include the development of computer control software for directing the polishing tool and the construction of a polishing testbed.

  10. Valuation of the EQ-5D-5L with composite time trade-off for the German population – an exploratory study

    Directory of Open Access Journals (Sweden)

    Kristina Ludwig


    Full Text Available Abstract Background The EuroQol Group has extended the severity levels of the EQ-5D from three to five (EQ-5D-5L. There are valuation studies worldwide planned in order to convert the EQ-5D-5L health states into a single preference-based summary score based on country-specific value sets of social health status preference valuations. The EuroQol Group developed an internationally standardised EQ-5D-5L valuation protocol. Based on the experiences of the first wave of valuation studies applying the protocol, a number of modifications to the implementation of composite time trade-off (cTTO were proposed and tested in an exploratory study in Germany. Methods The aim of the study is to test the improved EQ-5D-5L valuation protocol 1.1 and the implementation of three modifications: (1 introduction of ranking task, (2 separating time trade-off (TTO tasks for health states “Better Than Dead“(BTD/“Worse Than Dead” (WTD, (3 allow for removal of problematic valuations from the cTTO data (the feedback module. Data were collected in computer assisted personal interviews with 200 members of the German general public. Results In comparison to the first wave of valuation studies a higher data quality can be observed in both study arms: increasing number of WTD valuations, reduced inconsistencies for health state 55555 as well as higher values for mild health states. Comparing both study arms, mean observed cTTO value for severity 6 is higher in the test arm. The proportion of inconsistent cTTO responses is lower in the test arm than in the control arm and is further reduced by the feedback module. The ranking task prolongs the interview without the desired effect. Conclusions Both study arms yielded higher data quality in comparison to the first wave of EQ-5D-5L valuation studies. The valuation protocol combined with an intensive interviewer training and close data monitoring showed a high feasibility and acceptability to the respondents of the general

    Bak, Ewelina; Marcisz, Czeslaw; Nowak-Kapusta, Zofia; Dobrzyn-Matusiak, Dorota; Marcisz, Ewa; Krzeminska, Sylwia


    The aim of the present paper was the assessment of the psychometric properties of the Polish language version of the Audit of Diabetes-Dependent Quality of Life (ADDQoL) questionnaire applied in Poland among patients with type 1 (T1DM) or type 2 diabetes (T2DM). The studies were carried out among 330 patients with diabetes including 115 with T1DM and 215 with T2DM. In all the patients the level of the quality of life was investigated using the Polish language version of the ADDQoL and the psychometric properties were determined taking into consideration internal consistency, the factor loading and intraclass correlations. It was demonstrated that the values of internal consistency determining the reliability of the Polish language version of the ADDQoL for the overall Cronbach's alfa coefficient were 0.92 in the studied patients with T1DM and 0.93 in the studied patients with T2DM and the values of the loading factor were respectively 0.39-0.79 and 0.35-0.81. In the study of the correlation between the components of the ADDQoL the correlation coefficients proved to be highly statistically significant: in patients with T1DM r = 0.46-0.74 and in patients with T2DM - r = 0.42-0.80. The Polish language version of the ADDQoL is a reliable tool useful for the assessment of the level of the quality of life of adult patients with T1DM or T2DM in Poland and is recommended to be used among Polish-speaking patients with diabetes.

Tzoneva is being elaborated based on a working Polish-Bulgarian-Russian electronic parallel corpus authored by Maksim Duszkin, Violetta Koseska-Toszewa and Joanna Satoła-Staśkowiak, and works by A. Tzoneva. It is the first corpus comparing languages belonging to three different Slavic language groups: western, southern and eastern. Works on the dictionary are based on Gramatyka konfrontatywna bułgarsko-polska (Bulgarian-Polish confrontative grammar and the proposed there semantic-oriented interlanguage. Two types of classifiers have been introduced into the dictionary: classic and semantic. The trilingual dictionary will present a consistent and homogeneous set of facts of grammar and semantics. The Authors point out that in a traditional dictionary it is not clear for example whether aspect should be understood as imperfective / perfective form of a verb or as its meaning. Therefore in the dictionary forms and meaning are separated in a regular way. Imperfective verb form has two meanings: state and configuration of states and events culminating in state. Also perfective verb form has two meanings: event and configuration of states and events culminating in event. These meanings are described by the semantic classifiers, respectively, state and event, state1 and event1. The way of describing language units, mentioned in the article, gives a possibility to present language material (Polish, Bulgarian, Russian in any required order, hence the article’s title.

Results of the study were compared with some data reported by other WADA accredited anti-doping laboratories. Totally, 13 631 urine samples taken from Polish athletes of both sexes, aged 10-67 years, performing 46 disciplines of sport were tested. Cannabinoids were detected in 267 samples. Among Polish athletes the relative number of positive THC (tetrahydrocannabinol samples was one of the highest in Europe. The group of young Polish athletes (aged 16-24 years was the most THC-positive. THC-positive cases were noted more frequently in male athletes tested during out of competitions. The so-called contact sports (rugby, ice hockey, skating, boxing, badminton, body building and acrobatic sports were those sports, where the higher risk of cannabis use was observed. The legal interpretation of some positive cannabinoids results would be difficult because of some accidental and unintentional use of the narcotics by sportsmen. It was concluded that national anti-doping organizations (NADO’s, which are competent to judge whether the anti-doping rules were violated, should take into account the possibility of non-intentional doping use of cannabinoids via passive smoking of marijuana.

    Buder, V; Augustin, M; Schäfer, I; Welsch, G; Catala-Lehnen, P; Herberger, K


    The prevention, early diagnosis and treatment of onychomycosis is of great importance for professional athletes to avoid physical limitations by complications. So far, there is only little data on the prevalence of dermatomycosis in professional athletes. The aim of the study was to detect the prevalence of dermatomycosis in professional football players compared to the general population. The prospective, non-interventional, controlled study on the prevalence of dermatomycosis in professional football players was carried out on football players of a German Bundesliga team compared with a previously studied, equivalently aged German working population. A questionnaire survey, a dermatological check-up and a microbiological detection of pathogens in cases of suspicion were performed. Data of 84 football players (n = 45 in 2013; n = 39 in 2015) were compared to data of n = 8186 male employees between 17 and 35 years of age. In the group of athletes, there were findings of 60.7% onychomycosis, 36.9% of tinea pedis and 17.8% of pityriasis versicolor. In the group of the age-equivalent general German working population the findings were: onychomycosis 3.3%, tinea pedis 3.2%, pityriasis versicolor 1.4%. Our study shows a clearly higher risk for fungal diseases of the skin especially on the feet of professional football players. The results show a necessity for elucidation within prevention and the establishment of an appropriate therapy of dermatomycosis for professional football players.

    Drozdz, M.


    The Polish energy-system needs intensive investments in new technologies, which are energy efficient, clean and cost effective. Since the early 1990s, the Polish economy has had practically full access to modern technological devices, equipment and technologies. Introducing new technologies is a difficult task for project teams, constructors and investors. The author presents a set of principles for project teams useful in planning and energy modernisation. Several essential features are discussed: Energy-efficient appliances and systems; Choice of energy carriers, media and fuels; Optimal tariffs, maximum power and installed power; Intelligent, integrated, steering systems; Waste-energy recovery; Renewable-energy recovery. In practice there are several difficulties connected with planning and realising good technological and economic solutions. The author presents his own experiences of energy-system modernisation of industrial processes and building new objects. (Author)

  5. Directly polished lightweight aluminum mirror (United States)

    ter Horst, Rik; Tromp, Niels; de Haan, Menno; Navarro, Ramon; Venema, Lars; Pragt, Johan


    During the last ten years, Astron has been a major contractor for the design and manufacturing of astronomical instruments for Space- and Earth based observatories, such as VISIR, MIDI, SPIFFI, X-Shooter and MIRI. Driven by the need to reduce the weight of optically ultra-stiff structures, two promising techniques have been developed in the last years: ASTRON Extreme Lightweighting [1][2] for mechanical structures and an improved Polishing Technique for Aluminum Mirrors. Using one single material for both optical components and mechanical structure simplifies the design of a cryogenic instrument significantly, it is very beneficial during instrument test and verification, and makes the instrument insensitive to temperature changes. Aluminum has been the main material used for cryogenic optical instruments, and optical aluminum mirrors are generally diamond turned. The application of a polishable hard top coating like nickel removes excess stray light caused by the groove pattern, but limits the degree of lightweighting of the mirrors due to the bi-metal effect. By directly polishing the aluminum mirror surface, the recent developments at Astron allow for using a non-exotic material for light weighted yet accurate optical mirrors, with a lower surface roughness ( 1nm RMS), higher surface accuracy and reduced light scattering. This paper presents the techniques, obtained results and a global comparison with alternative lightweight mirror solutions. Recent discussions indicate possible extensions of the extreme light weight technology to alternative materials such as Zerodur or Silicon Carbide.

    Wojciech J. Cynarski


    Full Text Available The purpose of this study is to explain the revival of Polish martial arts from the perspectives of cultural sociology, the sciences of physical culture, and the humanistic theory of martial arts. The Polish Martial Arts (Polskie Sztuki Walki are a subject still requiring serious scientific examination, even in Poland. There are few works concerning the history of Polish weapons, and most only describe techniques for wielding specific types of edged weapons. Nevertheless, there is a large group of enthusiasts trying to restore and cultivate the old Polish tradition, a tradition with heavy emphasis on the art of fencing. The author knows many of the people and facts presented here, from personal observation and from direct participation in these arts. As a disciple of the late Master Yoshio Sugino (10th-dan Kobudo Katori Shinto-ryu, he fought against the Polish saber champion, and he has taken part in joint exhibitions of Polish and Japanese fencing.

  9. [Mortality of Polish actors in 1981-1999]. (United States)

    Poznańska, Anna; Gajewski, Antoni K


    The objective of this study was to compare the mortality of Polish actors (males and females) with the general Polish population for the period 1981-1999 and for two sub-periods: 1981-1991 and 1992-1998. Initially the studied cohort included 3992 dramatic actors (2161 males, 1831 females) of age 18-80 years (at the moment of cohort entrance). After detailed data verification statistical analysis was made for 2120 actors and 1767 actresses, contributing 29477.1 and 24886.2 person-years of observation, respectively. A total of 633 deaths (368 males and 265 females) were noted during the analyzed period. Statistical approach based on the follow-up method. Comparison with the reference population (Polish males and females from urban areas) was made by means of the standardized mortality ratios (SMRs) and their 95% confidence intervals. Direct comparison of the selected subgroups' mortality based on the rate ratio analysis. Standardized mortality ratios were 0.739 (95%CI: 0.666-0.819) for the actors and 0.887 (95%CI: 0.784-1.001) for actresses. Mortality of the actors' cohort was found to be significantly lower than in the reference population during total analyzed period, whereas for actresses no significant differences were found. Age-specific SMR dependence was found. Statistically significant lowering of SMR was observed for actors up to 80 years old. Finally, it could be concluded that in contrast to the actresses' cohort the actors' mortality in 1992-1999 significantly decreased in relation to 1981-1991 period. Moreover, the decrease of the actors' mortality exceeded tendencies observed for Polish urban population.

    Rothe, Hans


    The article tries to avoid the common opinion of German liberal acclamation to the "heroic Poles" of 1830 by showing that these liberals did not see what the governments were faced with. It informs about the memories of Clausewitz and Boyen; analyses the early essays of Boyen, 1794/95; gives first knowledge about the late memoire of 1830, which unveils a quite different meaning on a Polish state; informs about the Polish state Boyen knew, describes his reaction and his continuing thinking as a liberal reformer of Prussia; tries to explain what was - incorrectly - called his "about-turn" ("Frontweschsel"); gives information on Boyens comparing Poland and Germany; mentions briefly Boyens proposal of an independent Poland and makes sure the actuality of the problem.

  12. History of Polish gastrointestinal radiology. (United States)

    Urbanik, A


    As early as several days after the publication of the information concerning Roentgen's discovery the first radiological examinations were performed in Poland. The new method was immediately introduced into medical practice, including gastroenterology. In that pioneer period the most important works were those by Walery Jaworski who was the first man in the world to perform an X-ray of gall stones as well as the stomach with the use of a contrast medium. In its more-than-a-hundred-year history Polish gastrointestinal radiology has attempted not only to catch up with the world science, but it also has made a considerable contribution to its development.

    Beeres-Scheenstra, Renske; Ohnsorg, Claudia; Candreia, Claudia; Heinzmann, Sybille; Castellanos, Susana; De Min, Nicola; Linder, Thomas E


    To evaluate foreign language acquisition at school in cochlear implant patients. Cohort study. CI center. Forty three cochlear implants (CI) patients (10-18 yr) were evaluated. CI nonusers and patients with CI-explantation, incomplete datasets, mental retardation, or concomitant medical disorders were excluded. Additional data (type of schooling, foreign language learning, and bilingualism) were obtained with questionnaires. German-speaking children with foreign tuition language (English and/or French) at school were enrolled for further testing. General patient data, auditory data, and foreign language data from both questionnaires and tests were collected and analyzed. Thirty seven out of 43 questionnaires (86%) were completed. Sixteen (43%) were in mainstream education. Twenty-seven CI users (73%) have foreign language learning at school. Fifteen of these were in mainstream education (55%), others in special schooling. From 10 CI users without foreign language learning, one CI user was in mainstream education (10%) and nine patients (90%) were in special schooling. Eleven German-speaking CI users were further tested in English and six additionally in French. For reading skills, the school objectives for English were reached in 7 of 11 pupils (64%) and for French in 3 of 6 pupils (50%). For listening skills, 3 of 11 pupils (27%) reached the school norm in English and none in French. Almost 75% of our CI users learn foreign language(s) at school. A small majority of the tested CI users reached the current school norm for in English and French in reading skills, whereas for hearing skills most of them were not able to reach the norm.

  17. Buffered Electrochemical Polishing of Niobium

    Energy Technology Data Exchange (ETDEWEB)

    Ciovati, Gianluigi [Thomas Jefferson National Accelerator Facility (TJNAF), Newport News, VA (United States); Tian, Hui [Thomas Jefferson National Accelerator Facility (TJNAF), Newport News, VA (United States); College of William and Mary, Williamsburg, VA (United States); Corcoran, Sean [Virginia Polytechnic Inst. and State Univ. (Virginia Tech), Blacksburg, VA (United States)


    The standard preparation of superconducting radio-frequency (SRF) cavities made of pure niobium include the removal of a 'damaged' surface layer, by buffered chemical polishing (BCP) or electropolishing (EP), after the cavities are formed. The performance of the cavities is characterized by a sharp degradation of the quality factor when the surface magnetic field exceeds about 90 mT, a phenomenon referred to as 'Q-drop.' In cavities made of polycrystalline fine grain (ASTM 5) niobium, the Q-drop can be significantly reduced by a low-temperature (? 120 °C) 'in-situ' baking of the cavity if the chemical treatment was EP rather than BCP. As part of the effort to understand this phenomenon, we investigated the effect of introducing a polarization potential during buffered chemical polishing, creating a process which is between the standard BCP and EP. While preliminary results on the application of this process to Nb cavities have been previously reported, in this contribution we focus on the characterization of this novel electrochemical process by measuring polarization curves, etching rates, surface finish, electrochemical impedance and the effects of temperature and electrolyte composition. In particular, it is shown that the anodic potential of Nb during BCP reduces the etching rate and improves the surface finish.

  19. Advanced techniques for computer-controlled polishing (United States)

    Schinhaerl, Markus; Stamp, Richard; Pitschke, Elmar; Rascher, Rolf; Smith, Lyndon; Smith, Gordon; Geiss, Andreas; Sperber, Peter


    Computer-controlled polishing has introduced determinism into the finishing of high-quality surfaces, for example those used as optical interfaces. Computer-controlled polishing may overcome many of the disadvantages of traditional polishing techniques. The polishing procedure is computed in terms of the surface error-profile and the material removal characteristic of the polishing tool, the influence function. Determinism and predictability not only enable more economical manufacture but also facilitate considerably increased processing accuracy. However, there are several disadvantages that serve to limit the capabilities of computer-controlled polishing, many of these are considered to be issues associated with determination of the influence function. Magnetorheological finishing has been investigated and various new techniques and approaches that dramatically enhance the potential as well as the economics of computer-controlled polishing have been developed and verified experimentally. Recent developments and advancements in computer-controlled polishing are discussed. The generic results of this research may be used in a wide variety of alternative applications in which controlled material removal is employed to achieve a desired surface specification, ranging from surface treatment processes in technical disciplines, to manipulation of biological surface textures in medical technologies.

  2. Sexuality and affection among elderly German men and women in long-term relationships: results of a prospective population-based study.

    Directory of Open Access Journals (Sweden)

    Britta Müller

    Full Text Available Satisfaction with sexual activity i.e. sexual satisfaction and the importance of sexuality and affection were analysed using data from the German "Interdisciplinary Longitudinal Study of Adult Development" (ILSE. At three measurement points, 1993-1995, 1997-1998, and 2004-2006 i.e. subjects' ages of 63, 67, and 74 years, participants' reports about their affection and sexual activity were collected. The sample of completed records used for this study consisted of 194 urban non-institutionalised participants, 68% male, all living with partners. Median levels of sexual satisfaction were reported, fluctuating between the measurement points of ages 63 to 74. Between baseline, first and second follow-up no differences were found in levels of sexual satisfaction, though at measurement points age 63 and 67 women were more satisfied than men. When measured at age 74, affection was given a higher priority than sexual activity. Although men and women reported similar priorities, sexual activity and affection were more important for men than for women. Satisfaction within the relationship can be predicted by the importance of affection, but not by that of sexual activity. Our results confirm the thesis of the 'second language of sexuality': for humans in their later years affection seems to be more important than for younger individuals.

  3. Occupied Europe and German art historiography: methodology and morals

    Directory of Open Access Journals (Sweden)

    Arnold Witte


    Full Text Available Review of Kunstgeschichte in den besetzten Gebieten 1939-1945, edited by Magdalena Bushart, Agnieszka Gasior and Alena Janatkova. Cologne/Weimar/Vienna: Böhlau, 2016. The art historiography of the period of German National-Socialism has made significant methodological progress in the last two decades, and the present volume widens the geographical scope to include the territories occupied between 1939 and 1945 by the German army. How did art historians in these countries respond to the expectations and demands of these new authorities? A range of studies on Czech, Polish, Dutch, Belgian and Lithuanian academics shows how they were either lured into cooperation with the Germans on the basis of ‘Aryan’ concepts of art and culture, or ostracized when not considered part of the German race. A range of other essays on German art historians show how they were actively involved in propaganda activities in occupied countries. Notwithstanding its geographical bias towards eastern Europe, this volume shows how important this exchange was for the course of the discipline in various regions, and that using archival research is a sine-qua-non for the study of art historiography in times of regime change.

  9. Changes of individual perception in psychosocial stressors related to German reunification in 1989/1990 and cardiovascular risk factors and cardiovascular diseases in a population-based study in East Germany. (United States)

    Bohley, Stefanie; Kluttig, Alexander; Werdan, Karl; Nuding, Sebastian; Greiser, Karin Halina; Kuss, Oliver; Markus, Marcello Ricardo Paulista; Schmidt, Carsten Oliver; Völzke, Henry; Krabbe, Christine; Haerting, Johannes


    Aim was to examine the relationship between individually perceived changes in psychosocial stressors associated with German reunification and cardiovascular effects. We hypothesised that higher levels of psychosocial stress related to German reunification were associated with an increase in cardiovascular risk factors and cardiovascular diseases (CVDs). Cross-sectional data from 2 cohort studies in East Germany were used: Cardiovascular Disease, Living and Ageing in Halle Study (CARLA), and Study of Health in Pomerania (SHIP). 2 populations in East Germany. CARLA study: 1779 participants, aged 45-83 years at baseline (812 women), SHIP study: 4308 participants, aged 20-79 years at baseline (2193 women). Psychosocial stressors related to reunification were operationalised by the Reunification Stress Index (RSI; scale from 0 to 10). This index was composed of questions that were related to individually perceived changes in psychosocial stressors (occupational, financial and personal) after reunification. To examine the associations between the RSI and each stressor separately with cardiovascular risk factors and CVD, regression models were used. RSI was associated with CVD in women (RR=1.15, 95% CI 1.00 to 1.33). Cardiovascular risk factors were associated with RSI for both men and women, with strongest associations between RSI and diabetes in women (RR=1.10, 95% CI 1.01 to 1.20) and depressive disorders in men (RR=1.15, 95% CI 1.07 to 2.77). The change in occupational situation related to reunification was the major contributing psychosocial stressor. We observed a strong association with CVD in women who experienced occupational deterioration after reunification (RR=4.04, 95% CI 1.21 to 13.43). Individually perceived deterioration of psychosocial stressors (occupational, financial and personal) related to German reunification was associated with cardiovascular risk factors and CVD. The associations were stronger for women than for men. An explanation for these

    Polak, Jaroslav; Klepetková, Eva; Pošmourný, Josef; Šulc, Miroslav; Procháska, František; Tomka, David; Matoušek, Ondřej; Poláková, Ivana; Šubert, Eduard


    This paper describes a quest to find simple technique to superpolish Zerodur asphere (55μm departure from best fit sphere) that could be employed on old fashion way 1-excenter optical polishing machine. The work focuses on selection of polishing technology, study of different polishing slurries and optimization of polishing setup. It is demonstrated that either by use of fine colloidal CeO2 slurry or by use of bowl-feed polishing setup with CeO2 charged pitch we could reach 0.4nm RMS roughness while removing <30nm of surface layer. This technique, although not optimized, was successfully used to improve surface roughness on already prepolished Zerodur aspheres without necessity to involve sophisticated super-polishing technology and highly trained manpower.

  12. Determination of Exposure to the Alternaria Mycotoxin Tenuazonic Acid and Its Isomer allo-Tenuazonic Acid in a German Population by Stable Isotope Dilution HPLC-MS(3). (United States)

    Hövelmann, Yannick; Hickert, Sebastian; Cramer, Benedikt; Humpf, Hans-Ulrich


    The content of the Alternaria toxin tenuazonic acid and its isomer allo-tenuazonic acid was quantitated in urine of a German cohort (n = 48) using a newly developed and successfully validated solid phase extraction based stable isotope dilution HPLC-MS(3) method. Tenuazonic acid was detected in all of the samples and quantifiable in 97.9% of these samples in a range of 0.16-44.4 ng/mL (average = 6.58 ng/mL) or 0.07-63.8 ng/mg creatinine (average = 8.13 ng/mg creatinine). allo-Tenuazonic acid was for the first time detected in human urine (95.8% of the samples positive) and quantitated in 68.8% of the samples in a range of 0.11-5.72 ng/mL (average = 1.25 ng/mL) or 0.08-10.1 ng/mg creatinine (average = 1.52 ng/mg creatinine), representing 3.40-25.0% of the sum of both isomers (average = 12.4%). Food-frequency questionnaires were used to document food consumption of study participants to correlate mycotoxin exposure to nutritional habits. Although no statistically significant correlation between consumption of a specific food and urinary excretion of tenuazonic acid could be determined, a trend regarding elevated intake of cereal products and higher excretion of tenuazonic acid was evident. On the basis of these results, a provisional mean daily intake (PDI) for both tenuazonic acid and allo-tenuazonic acid was calculated, being 0.183 and 0.025 μg/kg body weight, respectively. A combined mean PDI for both isomers amounts to 0.208 μg/kg body weight with the highest individual PDI for one of the participants (1.582 μg/kg body weight) slightly exceeding the threshold of toxicological concern assumed for tenuazonic acid by the European Food Safety Authority of 1.500 μg/kg body weight. This is the first study to investigate the tenuazonic acid content in human urine of a larger sample cohort enabling the calculation of PDIs for tenuazonic acid and allo-tenuazonic acid.

    Róża Bazińska


    Full Text Available Background The aim of this article is to present research on the validity and reliability of the Collective Self-Esteem Scale (CSES for the Polish population. The CSES is a measure of individual differences in collective self-esteem, understood as the global evaluation of one’s own social (collective identity. Participants and procedure Participants from two samples (n = 466 and n = 1,009 completed a paper-pencil set of questionnaires which contained the CSES and the Rosenberg Self-Esteem Scale (RSES, and subsets of participants completed scales related to a sense of belonging, well-being and psychological distress (anxiety and depression. Results Like the original version, the Polish version of the CSES comprises 16 items which form the four dimensions of collective self-esteem: Public collective self-esteem, Private collective self-esteem, Membership esteem and Importance of Identity. The results confirm the four-factor structure of the Polish version of the CSES, support the whole Polish version of the CSES as well as its subscales, which represent satisfactory reliability and stability, and provide initial evidence of construct validity. Conclusions As the results of the study indicate, the Polish version of the CSES is a valid and reliable self-report measure for assessing the global self-esteem derived from membership of a group and has proved to be useful in the Polish context.

  14. Personality of Polish gay men and women

    Directory of Open Access Journals (Sweden)

    Marcin Kwiatkowski


    Full Text Available Background Sexuality is a part of one’s identity and personality that is shaped under the influence of biological and environmental factors and interactions with society. The results of research conducted so far and concerning the personality traits of gay men and women are not consistent, and only a small number of them concern the Polish population. Hence the objective of the present research was to provide personality profiles of men and women with different sexual orientations. Participants and procedure The participants (N = 346 included 84 gay women, 82 gay men, 95 heterosexual women and 85 heterosexual men. The following measures were used: a survey developed by the author, the Kinsey Scale, the EPQ-R (Eysenck Personality Questionnaire Revised adapted by Brzozowski and Drwal (1995, and the Sixteen-factor Personality Questionnaire of Cattell adapted by Nowakowska (1970. Results The results support the hypothesis that gay women and heterosexual men share similar personality traits, while gay men have more diverse traits, similar to the traits typical for heterosexual women and men. In particular, personalities of gay men are described by such traits as progressive attitude, independence, or willingness to take risks, which means traits linked to factor Q1. The highest values of that factor are observable in the case of gay men, as compared to gay women, and also in comparison with heterosexual men and women. Conclusions Sexual orientation is responsible for differences in personality traits of the studied group to a greater extent than their biological sex.

The EP infrastructure is capable to handle single-cell structures and the standard TESLA/ TTF nine-cell cavities. Several electro polishing processes have been made since and acceleration voltage up to 40 MV/m have been reached in nine cell structures. We report on measurements and experiences gained since 2003 as well as on handling procedures developed for the preparation of electro polished resonators. Specific data like heat production, variation of current density and bath aging will be presented. Another important point for reproducible results is the quality control of the electro polishing process. First quality control steps to be implanted in the EP procedure for large-scale production will be described.

    Jelena Nikolić


    Full Text Available Through the application of semiological analysis to theater posters made by two Polish authors, the paper uncovers signs, meanings, codes and specifics of the „Polish school of poster-making“ and contemporary Polish posters. Aside from this, I suggest a methodological framework for studying the issue of coding and shaping a theater poster as a culturally specific form of visual communication. The aesthetic and semiotic outlook of the Polish theater posters which were chosen is analyzed using the semiological method which highlights their differences and similarities. By pointing out the system of codes through the examples given here, a graphic designer is informed about the existence and the possibilities of a more systematic approach to shaping a theater poster.

  19. Frequency of Spiritual/Religious Practices in Polish Patients with Chronic Diseases: Validation of the Polish Version of the SpREUK-P Questionnaire

    Directory of Open Access Journals (Sweden)

    Arndt Büssing


    Full Text Available In order to measure a wide spectrum of organized and private religious, spiritual, existential and philosophical practices, the SpREUK-P (SpREUK is the German language acronym of “Spirituality/Religiosity and Coping with Illness” questionnaire was developed as a generic instrument. To account for the fact that institutional religiosity declines, not only in Europe, and to explore the alternative use of various existing esoteric and spiritual resources, the instrument also addresses non-religious forms of spiritual practices. Previously, it was tested in a more secular context and was found to be of relevance for atheistic/agnostic individuals. Now we intended to apply the instrument to 275 Polish individuals with chronic diseases (100% Catholics, 74% women, mean age 56 ± 16 years. The factorial structure of the SpREUK-P’s Polish version was similar to the primary version, but lacked an exclusive “spiritual (mind-body practices” subscale. Factor analysis revealed four main factors, which would explain 67% of the variance, i.e., religious practices (Cronbach’s alpha = 0.90, humanistic practices (alpha = 0.87, existentialistic practices (alpha = 0.80 and gratitude/awe (alpha = 0.80. The correlation pattern underlines construct validity. Interestingly, in Polish individuals, existentialistic practices did not significantly differ between religious and non-religious individuals (nor between men and women, while all other forms of spiritual practices did differ significantly.

  20. The German Adaptation and Standardization of the Personality Assessment Inventory (PAI). (United States)

    Groves, Julia A; Engel, Rolf R


    We developed the German Adaptation of the Personality Assessment Inventory (PAI; Morey, 1991) under careful consideration of current adaptation literature and guidelines. The adaptation process included the translation of the 344 items into German, a back translation into English as well as the testing of the language equivalence using a bilingual sample. We then standardized the final German version of the PAI for the German population. We compared the American and German norm and reliability data. The observed differences in PAI scale means did not exceed 5 T scores. Internal consistency reliability showed a similar pattern in both language versions, although the German alpha coefficients were on average slightly lower than the American ones. Factor structure was similar in both versions. We discuss expectations about the German PAI and possible problems for its practical usefulness for the German-speaking population.

  6. Conformal polishing approach: Tool footprint analysis

    Directory of Open Access Journals (Sweden)

    José A Dieste


    Full Text Available Polishing process is one of the most critical manufacturing processes during a metal part production because it determines the final quality of the product. Free-form surface polishing is a handmade process with lots of rejected parts, scrap generation and time and energy consumption. Two different research lines are being developed: prediction models of the final surface quality parameters and an analysis of the amount of material removed depending on the polishing parameters to predict the tool footprint during the polishing task. This research lays the foundations for a future automatic conformal polishing system. It is based on rotational and translational tool with dry abrasive in the front mounted at the end of a robot. A tool to part concept is used, useful for large or heavy workpieces. Results are applied on different curved parts typically used in tooling industry, aeronautics or automotive. A mathematical model has been developed to predict the amount of material removed in function of polishing parameters. Model has been fitted for different abrasives and raw materials. Results have shown deviations under 20% that implies a reliable and controllable process. Smaller amount of material can be removed in controlled areas of a three-dimensional workpiece.

  7. Laser polishing of additive manufactured Ti alloys (United States)

    Ma, C. P.; Guan, Y. C.; Zhou, W.


    Laser-based additive manufacturing has attracted much attention as a promising 3D printing method for metallic components in recent years. However, surface roughness of additive manufactured components has been considered as a challenge to achieve high performance. In this work, we demonstrate the capability of fiber laser in polishing rough surface of additive manufactured Ti-based alloys as Ti-6Al-4V and TC11. Both as-received surface and laser-polished surfaces as well as cross-section subsurfaces were analyzed carefully by White-Light Interference, Confocal Microscope, Focus Ion Beam, Scanning Electron Microscopy, Energy Dispersive Spectrometer, and X-ray Diffraction. Results revealed that as-received Ti-based alloys with surface roughness more than 5 μm could be reduce to less than 1 μm through laser polishing process. Moreover, microstructure, microhardness and wear resistance of laser-polished zone was investigated in order to examine the thermal effect of laser polishing processing on the substrate of additive manufactured Ti alloys. This proof-of-concept process has the potential to effectively improve the surface roughness of additive manufactured metallic alloy by local polishing method without damage to the substrate.

    Full Text Available Working in tandem with the use of information and communication technologies is well-known and frequently used as a method of supporting learning of foreign languages in authentic communication. It is based on a constructivist approach to teaching. In the reported case study Polish and Chinese students discussed in English preprepared topics. The work shows the potential of e-learning at the micro level, as the language and intercultural task is implemented into an academic course without modification of the objectives and learning outcomes of the course. Evaluation carried out at the end of the project indicates that both groups perceived the task as a significant linguistic, cultural and personal experience. They stressed the importance of sharing “culture for culture” as the partner culture was new for most of them. The ability to talk and respond to information which was often strange, from the point of view of their own culture, allowed for learning intercultural competence ̔in action’.

  9. German for physicists (United States)

    Stein, Ben


    "German is the language of science" I remember my father telling me as a boy growing up in the Bronx in New York during the 1970s. As I watched astronomy programmes on TV with my father and older brothers, I imagined having to speak ceaselessly in fluent German if I was ever to become a scientist as a grown-up. But when I started my studies at university in New York in the 1980s, I realized my father's advice - sought from weekly trips to the neighbourhood public library - was way out of date. Not only did my physics professors present their research in English at conferences all around the world, but they also published in English-language journals - thus seemingly not needing a single word of German.

  10. The German risk study. Pt. 2

    International Nuclear Information System (INIS)

    Burkart, K.


    A severe nuclear power plant accident can be followed by a considerable release of radioactive effluents into the atmosphere. Due to atmospheric dispersion, areas of different sizes can be contaminated. The corresponding doses can cause early illnesses, early fatalities, latent effects and genetic effects. They are accompanied by economic effects. Within the consequence model of the German Risk Study, early and late fatalities and genetically significant doses are calculated. The calculations are based on real data or phenomena such as the population around 19, present or future German sites, or 115 real weather sequences, as well as on models such as an atmospheric dispersion model, a dose model, a model of protective actions or a health effects model. Within this lecture, the consequence model applied in the German Risk Study will be discussed in detail and the results will be presented. (orig./RW)

    de Mol, Friederike; Gerowitt, Bärbel; Kaczmarek, Sylwia


    The question on intraregional versus inter-regional variability in herbicide sensitivity for weed populations is of major importance, both in extrapolation of model parameters and in herbicide zonal approval procedures. We hypothesised that inter-regional variability in herbicide sensitivity...... for field populations would be the same as intraregional variability for regions with similar climatic conditions. Seeds of field weed populations were collected in a Danish, German and Polish region. Herbicide sensitivity was tested in dose–response experiments in the glasshouse with flufenacet...... and iodosulfuron (Apera spica-venti), florasulam and tribenuron (Tripleurospermum inodorum), diflufenican, diflufenican + flurtamone and pendimethalin (Viola arvensis).

  13. [Romanticism in German medicine in the light of home historiography of 1802-1945]. (United States)

    Plonka-Syroka, B


    The German non-materialist medicine of the first half of the 19th century is presently a subject of advanced historical studies, carried out in Europe and USA. Until the mid-20th century, however, it was only the German authors who produced literature dedicated to the above-mentioned medicine. The purpose of this study is to present to the Polish reader the main trends in the German medical historiography that have been taking up the subject for 150 years. The historians of German medicine distinguished trends in the post-war period as the studies of the history of their native medical historiography developed. A Polish historian taking up the task of characterizing of the main methodological trends in German medical historiography is faced with the necessity to take position on the findings of German authors who took up the above-mentioned subject earlier. In my studies I worked mainly on the findings of the following authors: Nelly Tsouyopoulos, Urban Wiesing and Hans-Uwe Lammel. They served me as a guide to the old historical-medical literature that I managed to reach in the libraries of Dresden and Leipzig. Some of the German studies (H. Haeser, J. Petersen) were translated to Polish language and in those cases I leaned on the Polish translators. In this study I discuss the following methodological trends in historiography of German medicine of the 1st half of the 19th century: eclectic trends, philosophical trends, positivistic trends, neo-romantic trends, and social-cultural trends. I also present the analysis of theories of the most important representatives of the trends. Thanks to this I could reconstruct the process of shaping of the discussed epoch image in the light of various concepts of its description. As a result different characteristics of the epoch were grasped although the factography level they referred to was common. This study outlines also further developoment of the historiography of the discussed subject in the second half of the 20th

  14. Polishing for glass ceramics: which protocol? (United States)

    Silva, Tânia Mara da; Salvia, Ana Carolina Rodrigues Danzi; Carvalho, Rodrigo Furtado de; Pagani, Clovis; Rocha, Daniel Maranha da; Silva, Eduardo Galera da


    The execution of adjustments on ceramic restorations is sometimes necessary for either correction of occlusion and/or inadequate contours or esthetical improvements. Clinically, the surfaces undergo weariness through fine grinding diamond burs which remove the superficial glazing layer. Several materials for ceramic polishing have been used in an attempt to reach a satisfactory surface smoothness. The aim of this study was to perform a literature review on different polishing protocols of several dental ceramics. This is a literature review performed through scientific articles published between 2004 and 2012, indexed in MEDLINE, PubMed and Scielo databases. The study selected and analyzed a total of 20 relevant articles that evaluated different types of ceramics, polishing treatment and surface roughness. After an extensive literature review, this study observed: 1 - after the rupture of the glazing layer due to the adjustments of the restorations, the best choice for the polishing of the surface will depend on the type of ceramics used; 2 - glazing procedure provide excellent results regarding to the superficial smoothness; however, if reglazing is impossible, either abrasive rubber cups/points or sandpaper discs followed by the use of diamond polishing pastes results in a satisfactory superficial smoothness; 3 - clinical studies that take into account the behavior of the protocols polishing are scarce and should be encouraged; 4 - the large number of variables influence the final outcome of polishing should be considered.

  15. Stage of cancer diagnoses among migrants from the former Soviet Union in comparison to the German population - are diagnoses among migrants delayed? (United States)

    Cho, An Bin; Jaehn, Philipp; Holleczek, Bernd; Becher, Heiko; Winkler, Volker


    In this study, we compared stage at diagnosis, standardized incidence ratio (SIR) and standardized mortality ratio (SMR) of most frequent cancer diagnoses between re-settlers (Aussiedler) from the former Soviet Union and the general population in the Saarland in Germany to assess possible delays in diagnosis of cancer among this migrant group. Lung cancer, colorectal cancer, breast cancer, prostate cancer, malignant melanoma of the skin and stomach cancer diagnoses among a cohort of 18,619 re-settlers living in the Saarland between 1990 and 2009 were identified by the federal state's cancer registry. Vital status was available for the respective time-period and used to calculate SIR and SMR in comparison to the autochthonous population. Tumor stages were condensed into local and advanced stages. Odds ratios (OR) for an advanced tumor stage were modeled in dependence of re-settler-status and relevant covariates by logistic regression. Missing values were addressed in a sensitivity analysis. The influence of duration of stay in Germany on advanced stage diagnosis was analyzed among re-settlers. SIR and SMR of lung and breast cancer were lower among female re-settlers, while SIR and SMR of colorectal and prostate cancer were lower among male re-settlers. SIR and SMR of stomach cancer were elevated among both sexes. Female re-settlers showed an elevated OR for being diagnosed with advanced stage breast cancer. Both male and female re-settlers showed an elevated OR when observing all six sites combined (OR among males 1.47, p = 0.04; OR among females 1.37, p = 0.05). The result of elevated ORs was supported in the sensitivity analysis. Finally, male re-settlers showed a weak association between duration of stay in Germany and reduced risk for advanced stage diagnosis. Re-settlers were more likely to be diagnosed at an advanced tumor stage. These findings are in line with previous research having shown unfavorable health care utilization of re-settlers. Overall

  17. The relevance of unrelated costs internal and external to the healthcare sector to the outcome of a cost-comparison analysis of secondary prevention: the case of general colorectal cancer screening in the German population. (United States)

    Tscheulin, Dieter K; Drevs, Florian


    The potential of secondary prevention measures, such as cancer screening, to produce cost savings in the healthcare sector is a controversial issue in healthcare economics. Potential savings are calculated by comparing treatment costs with the cost of a prevention program. When survivors' subsequent unrelated health care costs are included in the calculation, however, the overall cost of disease prevention rises. What have not been studied to date are the secondary effects of fatal disease prevention measures on social security systems. From the perspective of a policy maker responsible for a social security system budget, it is not only future healthcare costs that are relevant for budgeting, but also changes in the contributions to, and expenditures from, statutory pension insurance and health insurance systems. An examination of the effect of longer life expectancies on these insurance systems can be justified by the fact that European social security systems are regulated by the state, and there is no clear separation between the financing of individual insurance systems due to cross-subsidisation. This paper looks at how the results of cost-comparison analyses vary depending on the inclusion or exclusion of future healthcare and non-healthcare costs, using the example of colorectal cancer screening in the German general population. In contrast to previous studies, not only are future unrelated medical costs considered, but also the effects on the social security system. If a German colorectal cancer screening program were implemented, and unrelated future medical care were excluded from the cost-benefit analysis, savings of up to 548 million euros per year would be expected. The screening program would, at the same time, generate costs in the healthcare sector as well as in the social security system of 2,037 million euros per year. Because the amount of future contributions and expenditures in the social security system depends on the age and gender of the

  18. Explanatory models of addictive behaviour among native German, Russian-German, and Turkish youth. (United States)

    Penka, S; Heimann, H; Heinz, A; Schouler-Ocak, M


    In Germany, the public system of addiction treatment is used less by migrants with addictive disorders than by their non-migrant counterparts. To date, the literature has focused primarily on language, sociocultural factors, and residence status when discussing access barriers to this part of the health care system. However, little attention has been paid to cultural differences in explanatory models of addictive behaviour. This is surprising when we consider the important role played by popular knowledge in a population's perceptions of and responses to illnesses, including their causes, symptoms, and treatment. In the present study, we examined explanatory models of addictive behaviour and of mental disorders in 124 native German und Russian-German youth and compared these models to those observed in an earlier study of 144 German and Turkish youth. We employed the free listing technique German and to compile the terms that participating subjects used to describe addictive behaviour. Subsequently, we examined how a subset of our study population assigned these terms to the respective disorders by means of the pile sort method. Although the explanatory models used by the German and Russian-German youth in our study were surprisingly similar, those employed by Turkish youth did not make any fundamental distinction between illegal and legal drugs (e.g. alcohol and nicotine). German and Russian-German youth regarded eating disorders as "embarrassing" or "disgraceful", but Turkish youth did not. Unlike our German and Russian-German subjects, the Turkish youth did not classify eating disorders as being addictive in nature. Moreover, medical concepts crucial to a proper understanding of dependence disorders (e.g. the term "physical dependence") were characterised by almost half of our Turkish subjects as useless in describing addictions. These findings show that it is impossible to translate medical or everyday concepts of disease and treatment properly into a different

  19. APS 3D: a new benchmark in aspherical polishing (United States)

    Gauch, Daniel; Mikulic, Dalibor; Veit, Christian


    The APS 3D system performs polishing and form correction in one step in order to reduce overall process time, reduce the number of polishing steps required and eliminate the need for highly skilled operators while providing a repeatable polishing process. This new 3D Polishing system yields better surface quality, and a better slope error, automatically determining the optimum speeds, feed rates and polish pressures to achieve a deterministic process based on the required quality parameters input by the operator. The process flow is always the same to ensure consistent quality and target quality values are defined before polishing begins.

  20. Leukemia in the proximity of a German boiling water nuclear reactor: Evidence of population exposure by chromosome studies and environmental radioactivity

    International Nuclear Information System (INIS)

    Dannheim, B.; Heimers, A.; Oberheitmann, B.; Schmitz-Feuerhake, I.; Schroeder, H.; Ziggel, H.


    The detection of an exceptional elevation of leukemia in children appearing 5 years after the start-up of the nuclear power plant Kruemmel in 1983, accompanied by a significant increase of leukemia cases in adults gave rise for investigations of radiation exposures of the population living near to the plant. The rate of dicentric chromosomes in peripheral blood lymphocytes of 7 parents of leukemia children and 14 other inhabitants in the proximity of the plant was significantly elevated and showed ongoing exposures over the years of operation. This finding gives rise to the hypothesis that chronic leakages by the reactor had occurred. This assumption is supported by the identification of artificial radioactivity in air, rain water, soil, and vegetation registered by the regular environmental monitoring programme of the nuclear power plant. Calculations of the corresponding source terms show that the originating emissions must have been well above authorized annual limits. The bone marrow dose is supposed to be originated mainly by incorporating of bone-seeking β- and α-emitters. (author)

  1. Polymorphism in the upstream regulatory region of DQA1 genes and DRB1, QAP, DQA1, and DQB1 haplotypes in the German population. (United States)

    Haas, J P; Kimura, A; Andreas, A; Hochberger, M; Keller, E; Brünnler, G; Bettinotti, M P; Nevinny-Stickel, C; Hildebrandt, B; Sierp, G


    Polymorphism in the URR of the MHC class II DQA1 gene defines ten different alleles named QAP. Oligotyping for the alleles of DRB1, QAP, DQA1, and DQB1 have been performed in 210 unrelated healthy controls from Germany. Moreover, 83 HTCs from the Tenth IHWS have been tested. Four point loci haplotypes (DRB1, QAP, DQA1, and DQB1) have been analyzed in the unrelated healthy population sample. Computer analysis of the linkage disequilibria leads to the conclusion that QAP alleles are in strong linkage disequilibrium with alleles either the DQA1 or the DRB1 locus. One typical ("common") haplotype was found to be associated with each DRB1 allele in the majority (86%) of the tested persons. Apart from that, 25 other less frequent ("unusual") haplotypes, with an overall frequency of 14% have been defined. Some of these "unusual" MHC class II haplotypes were found to differ only in the regulatory alleles of DQA1 (QAP alleles) while they are identical for the alleles coding for structural elements (DRB1, DQA1, and DQB1). Most of the "unusual" haplotypes were found to carry HLA-DQ6. Assuming that "unusual" (= rare) haplotypes have arisen from "common" (= frequent) haplotypes by point mutation and recombination, we propose the existence of three recombination sites in the MHC DR-DQ region: one between DRB1 and QAP, the second between QAP and DQA1, and the third between DQA1 and DQB1.

    Full Text Available The article highlights the nature of the Soviet totalitarian ethnic policy and its influence on the origin of the Polish opposite movement in Western Ukraine at the beginning of the Second World War. It also clarifies the main factors of the formation of active opposite movements among the Polish part of population in the Western Ukraine territory, which withdrew to the Soviet Union due to the distribution of Poland as a result of the Molotov-Ribbentrop Pact. The author defined category of Polish nationality persons, who were dissatisfied with Stalin’s repressive policies in 1939-1941 and become that social environment, in which finally formed opposite movement to totalitarianism and, in particular, antinational regime against the Polish ethnos, and the environment from which later appeared activists of this movement. By the author was analyzed the activity of Soviet authorities in the occupied territories of the former «Wshodnih kresuv» of the Second Rich Pospolyta and determined main factors that led to dissatisfaction with the rigid Soviet policy against the former government officials, military precipitators and servants of the Roman Catholic Church. Investigated and determined features of the Polish opposite movement formation in the former eastern Polish territories occupied in 1939 by the Soviet Union and seized in 1941 by Nazi Germany. The article also describes the origin and activity of the first underground Polish armed forces on Ukrainian territory.

    Antje Löffler

    Full Text Available The Three-Factor-Eating-Questionnaire (TFEQ is an established instrument to assess eating behaviour. Analysis of the TFEQ-factor structure was based on selected, convenient and clinical samples so far. Aims of this study were (I to analyse the factor structure of the German version of the TFEQ and (II--based on the refined factor structure--to examine the association between eating behaviour and the body mass index (BMI in a general population sample of 3,144 middle-aged and older participants (40-79 years of the ongoing population based cohort study of the Leipzig Research Center for Civilization Diseases (LIFE Health Study. The factor structure was examined in a split-half analysis with both explorative and confirmatory factor analysis. Associations between TFEQ-scores and BMI values were tested with multiple regression analyses controlled for age, gender, and education. We found a three factor solution for the TFEQ with an 'uncontrolled eating', a 'cognitive restraint' and an 'emotional eating' domain including 29 of the original 51 TFEQ-items. Scores of the 'uncontrolled eating domain' showed the strongest correlation with BMI values (partial r = 0.26. Subjects with scores above the median in both 'uncontrolled eating' and 'emotional eating' showed the highest BMI values (mean = 29.41 kg/m², subjects with scores below the median in all three domains showed the lowest BMI values (mean = 25.68 kg/m²; F = 72.074, p<0.001. Our findings suggest that the TFEQ is suitable to identify subjects with specific patterns of eating behaviour that are associated with higher BMI values. Such information may help health care professionals to develop and implement more tailored interventions for overweight and obese individuals.

The data are derived from the prospective controlled, well defined population based, multiple centre study that was performed in Germany for the first time in the years 2000-2001 with emphasis on quality management (structural, process, outcome) and regarding the patient's age, physical troubles, and impaired mental-cognitive, neurobehavioral functioning. TBI severity assessment is according to the Glasgow Coma Scale (GCS) score. Early outcome after rehabilitation is assessed by the Glasgow Outcome Scale (GOS) score of patients following rehabilitation and of 63% of all TBI with the aid of follow-up examination (simplified questionnaire) after one year. Catchment areas are Hanover (industrial) and Münster (more rural) with 2,114 million inhabitants. TBI is diagnosed according to ICD 10 S-02, S-04, S-06, S-07, S-09 with at least two of the following symptoms: dizziness or vomiting; retrograde or anterograde amnesia, impaired consciousness, skull fracture, and/or focal neurological impairment. Within one year 6.783 patients (58% male) were examined in the regional hospitals after acute TBI. The regional TBI incidence regarding hospital admission was 321/100.000 TBI. 28% of patients were 65 years of age. GCS was only assessed in 55% of patients. They were 90.9% mild, 3.9% moderate, and 5.2% severe TBI. A total of 5.221 TBI (= 77%) was hospitalised; 1.4% of them died. Only 258 patients (= 4.9%) of the hospitalized TBI received in-hospital neurorehabilitation (73% male), 68% within one month after injury. They were 10.9% severe, 23.4% moderate, and 65.7 mild TBI. 5% were 65 years. One-year follow-up examinations of 4307 individuals (= 63.5% of all TBI) are discussed. A total of 883 patients (= 20.6%) reported posttraumatic troubles, one half were > 64 years. One hundred and sixty patients (= 3

  6. Material removal mechanisms in abrasive vibration polishing of complex molds (United States)

    Brinksmeier, E.; Riemer, O.; Schulte, H.


    Optical and medical industries are demanding a large variety of optical elements exhibiting complex geometries and multitude opto-functional areas in the range of a few millimeters [1]. Therefore, mold inserts made of steel or carbides must be finished by polishing for the replication of glass and plastic lenses [2]. For polishing theses complex components in the shape of localized cavities or grooves the application of rotating polishing pads is very limited. Established polishing processes are not applicable, so state of the art is a time consuming and therefore expensive polishing procedures by hand. An automated process with conventional polishing machines is impossible because of the complex mold insert geometry. The authors will present the development of a new abrasive polishing process for finishing these complex mold geometries to optical quality. The necessary relative velocity in the contact area between polishing pad and workpiece surface is exclusively realized by vibration motions which is an advantage over vibration assisted rotating polishing processes. The absence of rotation of the pad opens up the possibility to machine new types of surface geometries. The specific influence factors of vibration polishing were analyzed and will be presented. The determination of material removal behavior and polishing effect on planar steel samples has shown that the conventional abrasive polishing hypothesis of Preston is applicable to the novel vibration polishing process. No overlaid chemical material removal appears.

  8. Surface Roughness and Gloss of Actual Composites as Polished With Different Polishing Systems. (United States)

    Rodrigues-Junior, S A; Chemin, P; Piaia, P P; Ferracane, J L


    This in vitro study evaluated the effect of polishing with different polishing systems on the surface roughness and gloss of commercial composites. One hundred disk-shaped specimens (10 mm in diameter × 2 mm thick) were made with Filtek P-90, Filtek Z350 XT, Opallis, and Grandio. The specimens were manually finished with #400 sandpaper and polished by a single operator using three multistep systems (Superfix, Diamond Pro, and Sof-lex), one two-step system (Polidores DFL), and one one-step system (Enhance), following the manufacturer's instructions. The average surface roughness (μm) was measured with a surface profilometer (TR 200 Surface Roughness Tester), and gloss was measured using a small-area glossmeter (Novo-Curve, Rhopoint Instrumentation, East Sussex, UK). Data were analyzed by two-way analysis of variance and Tukey's test (α=0.05). Statistically significant differences in surface roughness were identified by varying the polishing systems (pGrandio when polished with Sof-Lex and Filtek Z250 and Opallis when polished with Enhance. Gloss was influenced by the composites (p<0.0001), the polishing systems (p<0.0001), and the interaction between them (p<0.0001). The one-step system, Enhance, produced the lowest gloss for all composites. Surface roughness and gloss were affected by composites and polishing systems. The interaction between both also influenced these surface characteristics, meaning that a single polishing system will not behave similarly for all composites. The multistep systems produced higher gloss, while the one-step system produced the highest surface roughness and the lowest gloss of all.

    Brytek-Matera, Anna; Krupa, Magdalena; Poggiogalle, Eleonora; Donini, Lorenzo Maria


    There is a lack of Polish tools to measure behaviour related to orthorexia nervosa. The purpose of the present study was to validate the Polish version of the ORTHO-15 test. 341 women and 59 men (N = 400) were recruited, whose age ranged from 18 to 35 years. Mean age was 23.09 years (SD = 3.14) in women and 24.02 years (SD = 3.87) in men. The ORTHO-15 test and the EAT-26 test were used in the present study. Factor analysis (exploratory and confirmatory analysis) was used in the present study. Exploratory factor analysis performed on the initial 15 items from a random split half of the study group suggested a nine-item two-factor structure. Confirmatory factor analysis performed on the second randomly selected half of the study group supported this two-factor structure of the ORTHO-15 test. The Polish version of the ORTHO-15 test demonstrated an internal consistency (Cronbach's alpha) equal to 0.644. The Polish version of the ORTHO-15 test is a reliable and valuable instrument to assess obsessive attitudes related to healthy and proper nutrition in Polish female and male population.

  11. Evidence against ZNF469 being causative for keratoconus in Polish patients. (United States)

    Karolak, Justyna A; Gambin, Tomasz; Rydzanicz, Malgorzata; Szaflik, Jacek P; Polakowski, Piotr; Frajdenberg, Agata; Mrugacz, Malgorzata; Podfigurna-Musielak, Monika; Stankiewicz, Pawel; Gajecka, Marzena


    Keratoconus (KTCN) is a degenerative disorder characterized by stromal thinning and protrusion of the cornea, resulting in severe impairment of visual function. A recent study proposed that rare heterozygous mutations in ZNF469 determine KTCN aetiology. To investigate the contribution of ZNF469 to KTCN, we Sanger sequenced ZNF469 in 42 unrelated Polish patients with KTCN and 49 Polish individuals with high myopia (HM) and compared the results with whole-exome sequencing (WES) data performed in 268 Polish individuals without ocular abnormalities. The average number of ZNF469 non-synonymous variants was 16.31 and 16.0 for individuals with KTCN and HM, respectively (p = 0.3724). All identified variants were previously reported. Alternative allele frequency (AAF) was determined based on the WES results. Among missense variants, only one (rs528085780) has AAF ≤ 0.001 and was identified in one patient with sporadic KTCN. However, the resulting Arg1864Lys substitution was not predicted to be deleterious. In summary, we have not found a significant enrichment of sequence variants in ZNF469 in Polish patients with KTCN. High prevalence of ZNF469 variants identified in our KTCN group is typical for a common genetic variation observed in general population. Our findings indicate that variation in ZNF469 is not responsible for KTCN and other genetic variants are involved in the development and progression of this disease in Polish patients. © 2016 Acta Ophthalmologica Scandinavica Foundation.

    Kułaga, Zbigniew; Litwin, Mieczysław; Grajda, Aneta; Kułaga, Katarzyna; Gurzkowska, Beata; Góźdź, Magdalena; Pan, Huiqi


    The objective of this study was to construct blood pressure (BP) references with the use of a validated oscillometric device for normal-weight, school-aged children and adolescents and to study BP predictors. BP was measured in 14 266 randomly selected, normal-weight Polish children and adolescents aged 7-18 years, who were free of chronic disease, using a validated oscillometric device (Datascope Accutor Plus). Height, weight and waist circumference were measured. BP percentiles were constructed for age and height simultaneously with the use of a polynomial regression model. The normative values of BP were compared with the US normal-weight reference, German oscillometric reference, and Polish auscultatory reference. Reference BP percentiles by sex, age and height are presented. At median height, the age-specific differences in the 90th BP percentiles compared with German oscillometric reference ranged in the case of boys from -3 to 2  mmHg and from -5 to -1  mmHg, SBP and DBP, respectively, and in the case of girls from 0 to 3  mmHg and from -5 to -1  mmHg, SBP and DBP, respectively. As compared to weight, waist circumference was stronger SBP predictor in low birth weight boys. The study provides BP references for oscillmetric device, based on a current, nationally representative sample of normal-weight Polish children and adolescents. The normative values of BP were compared taking into consideration the height and BMI differences, the pubertal spurt, the methods of BP measurement and percentile construction.

  14. [German ophthalmologists and NSDAP (United States)

    Rohrbach, Jens Martin


    Approximately 40-45 % of all German physicians joined the National Socialist German Workers Party (NSDAP) until 1945. Reasons for party membership are manifold and still a matter of debate. Very likely, the extraordinary high representation of medical doctors in the NSDAP was rather a result of active entry than recruitment by the party. There are only few data concerning the willingness of ophthalmologists to become a party member ("Parteigenosse", "Pg"). According to the list of University teachers in Germany ("Hochschullehrerkarte"; Federal Archive, Berlin), the list of the members of the German Ophthalmological Society (DOG) of 1934 and especially the list of NSDAP-members (Federal Archive, Berlin) the following conclusions can be drawn: 1. Directors of German University eye hospitals (chairmen) were members of the NSDAP with a frequency of 23% in 1933 and 48% in 1938 as well as in 1943. The motivation for joining the party was most likely the perspective of acceleration of the academic career. 2. "Only" 30% of the ophthalmologists working in private praxis were "Pg" (until 1945). 3. Both chairmen and ophthalmologists in private praxis were equally hindered to join the NSDAP between May 1st 1933 and May 1st 1937 when the party temporarily stopped registration. 4. The majority of ophthalmologists who joined the NSDAP were born between 1880 and 1900 and thus had taken part in World War I as soldiers or had experienced the times of need after WW I. Only few ophthalmologists succeeded in the NS-hierarchy and probably only one ophthalmologist, Walther Löhlein from Berlin, came in personal contact with Adolf Hitler who was constantly in fear for his sight after his eye injury in October 1918. The "Law for the prevention of genetically disabled offsprings" ("Gesetz zur Verhütung erbkranken Nachwuchses") from July 14th, 1933 separated ophthalmologists into two parties: those advocating sterilization to a high degree and those recommending sterilization only

  3. Transformation of the Polish Banking Sector

    Directory of Open Access Journals (Sweden)

    Marek Stefański


    Full Text Available In the post-war period the banking system in Poland underwent two important system transitions: after 1946 and after 1989. The third transformation began after May 1, 2004, but it did not have a systemic character. The Polish banking sector started to operate on the Single European Market. The first part of the paper is devoted to the problems of the banks transformations after 1989 with a special focus on the quantitative development of banks in 19892008, and on subsequent privatisation and consolidation processes. The former intensified in 19891999, and the latter in 19992002. The consolidation process was very noticeable in the sector of cooperative banks after 1994. The second part of the paper includes an economic and financial analysis of the banks. A lot of attention was paid to the liquidity of the banking sector. It was assessed as good, which was confirmed by a short-term rating of Moodys and by the Financial Stability Report 2009, published by the National Bank of Poland in June 2009. The comparison of the net profit of the banking sector in 19972008 shows its dependence on the economic situation and policy. The number of banks with capital adequacy ratio well above the minimum required by the banking supervision is rising. The financial power ratings are not favorable for the domestic banks. The third part of the paper focuses on the development directions of the Polish banking sector. It may be concluded on the basis of the analysis that privatisation and consolidation processes will be continued. They will concentrate on the capital of foreign banks already operating in Poland. As compared with individual foreign banks, the potential of the Polish banking sector is week. The fourth part of the paper focuses on the presentation Polish banking sector in the context of European Union banking sector. The paper finishes with conclusions. Generally, Polish banks have to implement a strategy to enable them to compete on the Single

  4. Polish adaptation of Bad Sobernheim Stress Questionnaire-Brace and Bad Sobernheim Stress Questionnaire-Deformity. (United States)

    Misterska, Ewa; Głowacki, Maciej; Harasymczuk, Jerzy


    Bad Sobernheim Stress Questionnaire-Brace and Bad Sobernheim Stress Questionnaire-Deformity are relatively new tools aimed at facilitating the evaluation of long-term results of therapy in persons with idiopathic scoliosis undergoing conservative treatment. To use these tools properly in Poland, they must be translated into Polish and adapted to the Polish cultural settings. The process of cultural adaptation of the questionnaires was compliant with the guidelines of International Quality of Life Assessment (IQOLA) Project. In the first stage, two independent translators converted the originals into Polish. Stage two, consisted of a comparison of the originals and two translated versions. During that stage, the team of two translators and authors of the project identified differences in those translations and created a combination of the two. In the third stage, two independent translators, who were native speakers of German, translated the adjusted version of the Polish translation into the language of the original document. At the last stage, a commission composed of: specialists in orthopedics, translators, a statistician and a psychologist reviewed all translations and drafted a pre-final version of the questionnaires. Thirty-five adolescent girls with idiopathic scoliosis who were treated with Cheneau brace were subjected to the questionnaire assessment. All patients were treated in an out-patient setting by a specialist in orthopedics at the Chair and Clinic of Orthopedics and Traumatology. Median age of patients was 14.8 SD 1.5, median value of the Cobb's angle was 27.8 degrees SD 7.4. 48.6% of patients had thoracic scoliosis, 31.4% had thoracolumbar scoliosis, and 20% patients had lumbar scoliosis. Median results obtained by means of the Polish version of BSSQ-Brace and BSSQ-Deformity questionnaires were 17.9 SD 5.0 and 11.3 SD 4.7, respectively. Internal consistency of BSSQ-Brace and BSSQ-Deformity was at the level of 0.80 and 0.87, whereas the value of

  7. The German drought monitor (United States)

    Zink, Matthias; Samaniego, Luis; Kumar, Rohini; Thober, Stephan; Mai, Juliane; Schäfer, David; Marx, Andreas


    The 2003 drought event in Europe had major implications on many societal sectors, including energy production, health, forestry and agriculture. The reduced availability of water accompanied by high temperatures led to substantial economic losses on the order of 1.5 Billion Euros, in agriculture alone. Furthermore, soil droughts have considerable impacts on ecosystems, forest fires and water management. Monitoring soil water availability in near real-time and at high-resolution, i.e., 4 × 4 km2, enables water managers to mitigate the impact of these extreme events. The German drought monitor was established in 2014 as an online platform. It uses an operational modeling system that consists of four steps: (1) a daily update of observed meteorological data by the German Weather Service, with consistency checks and interpolation; (2) an estimation of current soil moisture using the mesoscale hydrological model; (3) calculation of a quantile-based soil moisture index (SMI) based on a 60 year data record; and (4) classification of the SMI into five drought classes ranging from abnormally dry to exceptional drought. Finally, an easy to understand map is produced and published on a daily basis on Analysis of the ongoing 2015 drought event, which garnered broad media attention, shows that 75% of the German territory underwent drought conditions in July 2015. Regions such as Northern Bavaria and Eastern Saxony, however, have been particularly prone to drought conditions since autumn 2014. Comparisons with historical droughts show that the 2015 event is amongst the ten most severe drought events observed in Germany since 1954 in terms of its spatial extent, magnitude and duration.

  8. Historical Roots of Generalized Trust in Polish Society

    Directory of Open Access Journals (Sweden)

    Borowiecki Łukasz


    Full Text Available The article analyses how historical events shape generalized trust in contemporary Polish society. The analysis consists of a set of logistic regression models. The impact of historical variables is controlled for age, sex, education and the size of the municipality. This is the first quantitative study on Poland that links historical events with the current levels of trust among Polish citizens. The common knowledge is that the Partitions of Poland had negative impact on trust. Literature on the topic hints that historical demo? graphics should play a role too. The findings suggest that Partitions had little impact with only Greater Poland and Pomerania having lower levels of generalized trust. Historical literacy rate and the presence of Ukrainian or Belarusian population are negatively associated with generalized trust while the abrupt migrations after the World War I are positively associated. The rapid character of migration is supposed to positively impact generalized trust by forcing individuals to cooperate and rely on people with whom they have no personal ties.

    Full Text Available The western Indo-European vocabulary in Baltic and Slavic is the result of an Indo-European substratum which contained an older non-Indo-European layer and was part of the Corded Ware horizon. The numbers show that a considerable part of the vocabulary was borrowed after the split between Baltic and Slavic, which came about when their speakers moved westwards north and south of the Pripet marshes. Germanic and Balto-Slavic were never contiguous Indo-European dialects at any stage of their prehistory.

    Full Text Available Finishing process like polishing is usually used to obtain high quality mechanical surface characteristics such as texture and roughness. These operations are mainly handmade and need highly trained operators thus limiting their repeatability and profitability. To optimize the industrialization of the polishing process, it is therefore necessary to modelize the process to built efficient parameter database. The aim of this study is to characterise the polishing of 316L stainless steel with structured abrasive belts. The geometric data of the belts are given, and we then propose a model to determine material removal. An experimental test bench is set up to test this model and characterise the polishing process in terms of forces. It produces samples for different polishing conditions. The different polished surfaces are then analyzed thanks to the roughness and the wettability. Using experimental designs, we are able to validate the proposed model and identify the parameters that influence a polishing operation.

According to the data of the International Diabetes Federation, in Poland 9% of the population between the ages of 20–79 suffer from diabetes. objective. The aim of this study was to investigate the differences in the prevalence of diabetes in urban and rural areas in Poland, and the preparation of a model describing the phenomenon. materials and method. Differences between urban and rural areas were studied for the occurrence of patients treated with diabetes per 100,000 inhabitants, the number of patients, structure of treatment per the used products, and the costs of reimbursement of treatment products between 2008–2012. Urban and rural cases were compared using zip codes. The basis for classifying a patient as being an inhabitant of an urban or rural area was an urban zip code of the declared place of residence. results. Differences were observed both between various areas of Poland, as well as depending on whether the declared place of residence of the patient was urban or rural. Differences between urban and rural areas within the studied period have increased. The difference in the prevalence of diabetes among the inhabitants of Podlaskie, Śląskie or Świętokrzyskie provinces is striking. conclusion. Differences between urban and rural areas which depend on morbidity and detection of patients in the earlier phase of illness, the structures of medical technologies used in the treatment process, the number of purchased pharmaceuticals, enable better monitoring of effectiveness and quality of politics on prevention and treatment of chronic diseases. It is important for the creation of a health policy to devise a system of indicators, which will enable a decrease in the existing differences between regions, and between the urban and rural areas within the provinces.

  19. The Polish Cyborg. A Reflection on the Relationship between Man and Machine in Early Polish Modernism

    Directory of Open Access Journals (Sweden)

    Emiliano Ranocchi


    Full Text Available Far from being enthusiastic “modernolatry” of Italian futurism, Polish futurism demonstrates an attitude of ambivalence toward modernity. This is particularly evident in the Polish approach to that very synecdoche of modernity which is the machine. In his essay of 1923, the leader of the group, Bruno Jasieński, compares the fetishistic cult of the machine, which characterizes the Italian approach, with the utilitarian one of the Russians, exemplified by a quote from Majakovskij. To these two propositions, as a sort of Hegelian synthesis, he adds a Polish one consisting in the conception of the machine as a prosthesis, a continuation of the human body. Thereby he introduces an idea later known as “cyborg”. The category of cyborg is also useful to understand the work of another today almost forgotten Polish writer of the Twenties, Jerzy Sosnkowski. He was the author of a short novel, A Car, You and Me (Love of Machines, in which a whole chapter concerns the chief character’s dystopian nightmare wherein machines take control over the world. The third section of the essay deals with the idea of man a machine – an old, 18th century conception, which became actual anew in the 20th century and whose traces we can find among others in a well-known poem by Tytus Czyżewski. Thirty years before N. Wiener, Polish modernists seem to have sensed the social, political and anthropological implications of the mechanization of work.

  20. Characterization and Streptococcus mutans adhesion on air polishing dentin. (United States)

    Tada, Kazuhiro; Oda, Hirotake; Inatomi, Michitomo; Sato, Soh


    Air polishing is known as an effective and time saving tooth cleaning method. However, this method increased surface roughness and bacterial adhesion on dentin surface. The aim of this study was to characterize and examine Streptococcus mutans adhesion on dentin surface after air polishing as compared to the conventional method. The dentin blocks (4 × 4 × 1 mm) were polished by a rubber cup with polishing material (Polishing) and air-polished by 25 μm glycine (G25), 65 μm glycine (G65), and 65 μm sodium bicarbonate (NHC65) microparticles. Surface roughness (Ra) was measured by a laser electron microscope. The amount of adhered S. mutans was quantified using a resazurin reduction assay (alamarBlue(®)). The Ra of G25 and G65 was significantly (p < 0.01) smaller than that of NHC65 and greater than that of Polishing. However, there was no significant difference in S. mutans adhesion among Polishing, G25, and G65, while NHC65 showed significantly (p < 0.01) higher S. mutans adhesion. Within the limitations of this in vitro study, air polishing using glycine microparticles conditioned S. mutans adhesion on dentin surface in a similar fashion than the conventional method, and less than air polishing using sodium bicarbonate microparticles.

  1. Effects of polishing procedures on color stability of composite resins. (United States)

    Güler, Ahmet Umut; Güler, Eda; Yücel, Ali Cağin; Ertaş, Ertan


    The purpose of this study was to investigate the effect of different polishing methods on color stability of posterior, universal and nanohybrid composite resin restorative materials upon exposure to a staining agent. Twenty-five specimens were prepared for each of 5 different composite resins (Filtek Z250, Filtek P60, Quadrant LC, Grandio and Filtek Supreme). Specimens were divided into 5 groups and different polishing procedures, including polishing discs (Pd), polishing discs then diamond polishing paste (PdP), polishing discs then a liquid polishing system (Biscover) (PdB), and combinations of these (PdPB) were used. Unpolished specimens served as the control (C). The specimens were stored for 48 h in a coffee solution. The color of all specimens was measured before and after exposure with a colorimeter, and total color change (DeltaE*) were calculated. The data were analyzed with a two-way ANOVA and the means were compared by Tukey HSD test (alpha=0.05). The lowest color difference was observed in the groups PdP and C, while the highest color difference was observed in PdPB, and PdB. When comparing the five different restorative materials, no significant difference was observed between FiltekP60 and FiltekZ250, and these materials demonstrated significantly less color change than Quadrant LC and the nanohybrid materials (Grandio, Filtek Supreme). The posterior (Filtek P60) and universal (Filtek Z250) composite resin restorative materials, which do not contain tetraethyleneglycol dimethacrylate (TEGDMA), were found to be less stainable than the nanohybrid (Grandio, Filtek Supreme) and universal (Quadrant LC) composite resins, which contain TEGDMA. The use of diamond polishing paste after polishing with polishing discs significantly decreased staining when compared to the groups that used polishing discs alone, for all restorative materials tested. The highest color change values were obtained for the specimens that were polished with the Biscover liquid polish

  5. German approach to VLLW management

    International Nuclear Information System (INIS)

    Broecking, D.


    Waste generated in German nuclear facilities is exhaustively and selectively manage through a system adapted to the waste's characteristics. The management of the waste ensures that the impact on the workers, population and the environment is acceptable. This is done through a detailed documentation and quality assurance program which applies not only to radioactive waste but also to cleanable material used within a licensed practice. In Germany the producer is responsible for the waste generated in a licensed facility and is therefore responsible for the correct disposal, which depends on the waste's characteristics. Since the waste producer requires a license for all activities involving radioactive substances, the atomic authority is continuously informed and can therefore monitor the producer for compliance with the regulations. The use and disposal of all material in a licensed practice is documented and can therefore be traced by the authorities. Clearance is seen in Germany as the best way of managing non-radioactive material in a licensed practice. Germany has developed clearance procedures which guarantee that after clearance the radiological impact is negligible. (author)

    Full Text Available This paper gives a general overview of Polish experience and achievements with regard to hydrodynamic modelling in the Polish zone of the Baltic Sea. The first work started already at the end of the sixties when the first 1D and 2D hydrodynamic models were set up. With the development of numerical methods and increasing computational power a number of 1D, 2D and 3D models were set up and tested. Global, regional and local models cover the most important water bodies,i.e. the Pomeranian Bay - Szczecin Lagoon and Gulf of Gdansk - Vistula Lagoon systems.

  8. The wear of polished and glazed zirconia against enamel. (United States)

    Janyavula, Sridhar; Lawson, Nathaniel; Lawson, Nathaniel; Cakir, Deniz; Beck, Preston; Ramp, Lance C; Burgess, John O


    The wear of tooth structure opposing anatomically contoured zirconia crowns requires further investigation. The purpose of this in vitro study was to measure the roughness and wear of polished, glazed, and polished then reglazed zirconia against human enamel antagonists and compare the measurements to those of veneering porcelain and natural enamel. Zirconia specimens were divided into polished, glazed, and polished then reglazed groups (n=8). A veneering porcelain (Ceramco3) and enamel were used as controls. The surface roughness of all pretest specimens was measured. Wear testing was performed in the newly designed Alabama wear testing device. The mesiobuccal cusps of extracted molars were standardized and used as antagonists. Three-dimensional (3D) scans of the specimens and antagonists were obtained at baseline and after 200 000 and 400 000 cycles with a profilometer. The baseline scans were superimposed on the posttesting scans to determine volumetric wear. Data were analyzed with a 1-way ANOVA and Tukey Honestly Significant Difference (HSD) post hoc tests (α=.05) Surface roughness ranked in order of least rough to roughest was: polished zirconia, glazed zirconia, polished then reglazed zirconia, veneering porcelain, and enamel. For ceramic, there was no measureable loss on polished zirconia, moderate loss on the surface of enamel, and significant loss on glazed and polished then reglazed zirconia. The highest ceramic wear was exhibited by the veneering ceramic. For enamel antagonists, polished zirconia caused the least wear, and enamel caused moderate wear. Glazed and polished then reglazed zirconia showed significant opposing enamel wear, and veneering porcelain demonstrated the most. Within the limitations of the study, polished zirconia is wear-friendly to the opposing tooth. Glazed zirconia causes more material and antagonist wear than polished zirconia. The surface roughness of the zirconia aided in predicting the wear of the opposing dentition

  12. Interviewing German scientists on climate change. A preliminary study

    Energy Technology Data Exchange (ETDEWEB)

    Ungar, S. [GKSS-Forschungszentrum Geesthacht GmbH (Germany). Inst. fuer Kuestenforschung; Toronto Univ., Scarborough (Canada)


    This study is based on in-depth interviews with 25 German scientists at the Coastal Research Institute of the GKSS-Forschungszentrum. It takes as its context the differential rhetoric and planning on climate change found in Germany and North America. The interviews try to throw light on the early German decision to address climate change, and to assess the current attitudes, beliefs and experiences of these German scientists. The results reveal a degree of complacency among these scientists, including a sense that Germany is not particularly threatened by climate change and has the capacity to adapt to it. The scientists are critical of inaction among the German population, but themselves uphold a ''light version'' of the precautionary principle. They have great difficulty translating the idea of climate change into popular metaphors that can be grasped by children. They strongly reject any link between German leadership on the issue as a result of a sense of guilt about the German past. (orig.)

  15. Assessing operability of a novel polisher arrangement using MMS

    International Nuclear Information System (INIS)

    Shor, S.W.W.


    A condensate polisher is intended to remove both particulate matter and ionic material from the condensate. Condensate polishers have normally been placed directly in the condensate system downstream of the condensate pumps. This inline location has certain disadvantages. These disadvantages are discussed. Placing the polisher in a sidestream location, where water is removed from the condensate system, pumped through the polisher, and then returned to the condensate system provides a solution to these disadvantages. Several possible types of sidestream installations is described. This has a polisher taking unpolished condensate from one compartment from one compartment of a divided hotwell in a specially modified condenser and returning polished condensate to the other compartment. The polisher is supplied by its own dedicated pumps, which have a head requirement sufficient only to overcome the pressure drop through the polisher circuit at a flow rate of 110% of maximum condensate flow. This concept is very attractive but has not yet been tested even though it is being installed in several new units. A simulation was, therefore, performed using MMS to provide confidence that this particular sidestream polisher arrangement was operationally viable

  17. Plasma electrolytic polishing of metalized carbon fibers

    Directory of Open Access Journals (Sweden)

    Falko Böttger-Hiller


    Full Text Available Efficient lightweight structures require intelligent materials that meet versatile functions. Especially, carbon-fiber-reinforced polymers (CFRPs are gaining relevance. Their increasing use aims at reducing energy consumption in many applications. CFRPs are generally very light in weight, while at the same time being extremely stiff and strong (specific strength: CFRPs: 1.3 Nm kg–1, steel: 0.27 Nm kg–1; specific stiffness: CFRPs: 100 Nm kg–1, steel: 25 Nm kg–1. To increase performance and especially functionality of CFRPs, the integration of microelectronic components into CFRP parts is aspired. The functionalization by sensors, actuators and electronics can enable a high lightweight factor and a new level of failure-safety. The integration of microelectronic components for this purpose requires a working procedure to provide electrical contacts for a reliable connection to energy supply and data interfaces. To overcome this challenge, metalized carbon fibers are used. Metalized fibers are, similar to the usual reinforcing fibers, able to be soldered and therefore easy to incorporate into CFRPs. Unfortunately, metalized fibers have to be pre-treated by flux-agents. Until now, there is no flux which is suitable for mass production without destroying the polymer of the CFRP. The process of plasma electrolytic polishing (PeP could be an option, but is so far not available for copper. Thus, in this study, plasma electrolytic polishing is transferred to copper and its alloys. To achieve this, electrolytic parameters as well as the electrical setup are adapted. It can be observed that the gloss and roughness can be adjusted by means of this procedure. Finally, plasma electrolytic polishing is used to treat thin copper layers on carbon fibers.

    Piotr Bórawski


    Full Text Available The objective of the paper was to recognize the efficiency of Polish agriculture. We have studied data from Main Statistical Office (MSO and compared the efficiency in the years 2000–2010. The data proved that the efficiency of Polish agriculture improved in the analyzed period. To measure the impact of macroeconomic variables we introduced these into the regression model. The macroeconomic factors included: X1 (nominal prices of land, X2 (land prices expressed in dt, X3 (inflation, X4 (investment in agriculture and hunting, X5 (balance of trade and X6 (GDP. We wanted to recognize the impact of macroeconomic factors on: Y1 (gross output, Y2 (intermediate consumption, Y3 (gross value added. Multiple regression was used to measure the impact of macroeconomic factors on global production of agriculture. The strongest impact on gross value added had: X4 (investment in agriculture and horticulture and X4 (trade balance. Poland is a member of European Union and the Common Agricultural Policy has improved the situation in agriculture. There are about 2 100 000 farms in Poland but only 300 000–400 000 are producing for the market. Other farms have social functions and are place for work for rural inhabitants.

  8. Farmers' pensions and the Polish economic crisis. (United States)

    Simanis, J G


    The Polish Government, in 1977, inaugurated a new pension program that made old-age and invalidity benefits available for the first time to most farmers in that country. The evolution and eventual failure of that program were closely intertwined with a growing national economic crisis, manifested in widespread popular unrest and culminating in emergence of the Solidarity movement. The farmers' pension program was originally presented as both a social security measure and a vehicle for improving agricultural efficiency. The economic situation was expected to benefit as farms of older owners were passed to younger, presumably more efficient, successors, with the state sometimes acting as intermediary. A further step to bind the social security concept to agricultural efficiency came through relating the pension amount to the quantity of produce the individual farmer sold to the state over a number of years. The failure of these provisions and other unpopular features of the new program was aggravated by inflation and continuing deterioration of the Polish economy.

  9. Robotic Automation in Computer Controlled Polishing (United States)

    Walker, D. D.; Yu, G.; Bibby, M.; Dunn, C.; Li, H.; Wu, Y.; Zheng, X.; Zhang, P.


    We first present a Case Study - the manufacture of 1.4 m prototype mirror-segments for the European Extremely Large Telescope, undertaken by the National Facility for Ultra Precision Surfaces, at the OpTIC facility operated by Glyndwr University. Scale-up to serial-manufacture demands delivery of a 1.4 m off-axis aspheric hexagonal segment with surface precision use of robots to automate currently-manual operations on CNC polishing machines, to improve work-throughput, mitigate risk of damage to parts, and reduce dependence on highly-skilled staff. Second is the use of robots to pre-process surfaces prior to CNC polishing, to reduce total process time. The third draws the threads together, describing our vision of the automated manufacturing cell, where the operator interacts at cell rather than machine level. This promises to deliver a step-change in end-to-end manufacturing times and costs, compared with either platform used on its own or, indeed, the state-of-the-art used elsewhere.

  10. Analytic tendencies in modern Polish and Russian

    Directory of Open Access Journals (Sweden)

    Wojciech Sosnowski


    Full Text Available Analytic tendencies in modern Polish and Russian Modern Polish and Russian are characterized by some features which demonstrate an increasing level of analitism. In the process of transformation from synthetic to analytical language, a crucial role is played by prepositional units. In this research, analitism is understood in a traditional way as a morphological and syntactic phenomenon. The fact that the synthetic structure of a language may, in some conditions, turn into an analytical one, as happened in the case of Bulgarian and Macedonian, has been intriguing linguists ever since, and has made me attempt to answer the question: What is the condition of modern Polish and Russian, which are languages with a rich literary tradition and solid grammatical norms, which belong to a group of synthetic languages? The analytical tendencies in morphology include the following: a decrease in the number of cases in all inflected parts of speech; a more frequent use of uninflected nouns and adjectives; the growing importance of nouns with common gender, and, in particular, the use of forms of masculine gender to depict feminine gender; differences in expressing collectiveness in a group of nouns (using collective meaning for forms that have singular meaning; substituting case forms with prepositions; substituting case forms with subordinate clauses; substituting case forms with “helper” words. Analytical tendencies in the area of numeral functioning include: substituting inflected forms of ordinal numerals with cardinal ones; the gradual disappearing inflection of numerals; confusing the forms of noun cases after numerals; the disappearing declination of collective numerals; displacing other cases with so-called simple cases; changing the syntactical position which the numeral should be inflected in; abandoning the declination of first elements of collective numerals. During the study of analytic tendencies in morphology, it was necessary to examine

  11. Original article Multidimensional versus unidimensional models of emotional contagion: the Emotional Contagion Scale in a Polish sample

    Directory of Open Access Journals (Sweden)

    Monika Wróbel


    Full Text Available Background The Emotional Contagion Scale (ECS measures individual differences in susceptibility to catching emotions expressed by others. Although initially the scale was reported to have a unidimensional structure, recent validation studies have suggested that the concept of emotional contagion is multidimensional. The aim of the study was therefore to test whether the structure of the ECS in a Polish sample corresponds with that observed for other non-English speaking populations. Participants and procedure The scale, translated into Polish, was completed by 633 university students in four independent samples. To investigate the factor structure of the ECS, confirmatory factor analyses of five alternative models were conducted. Results The results supported a multifaceted solution, which confirmed that susceptibility to emotional contagion may be differentiated not only across positive vs. negative states but also across discrete emotions. Moreover, the verification of internal consistency, test-retest reliability and construct validity of the Polish version indicated that its parameters are acceptable and comparable with the characteristics of other adaptations. Conclusions The Polish ECS, together with other adaptations of the scale, shows that the construct developed in the United States can be successfully measured in other cultural contexts. Thus, the Polish version can be treated as a useful tool for measuring individual differences in susceptibility to emotional contagion.

  19. Tourism-climate conditions and their future development in the Polish-Saxon border area

    Directory of Open Access Journals (Sweden)

    Bartłomiej Miszuk


    Full Text Available Current climate conditions and future changes, including impacts on the thermal bioclimate and tourism in the German-Polish border region, was one of the tasks investigated within the EU KLAPS project (Climate Change, Air Pollution and Critical Load of Eco Systems in the Polish-Saxon Border Region. The aim of this paper is to present the thermal bioclimate conditions and the influence of weather and climate on tourist issues in the KLAPS project domain, considering various types of recreation for both current and future periods. The base for the analysis was climatic data from the 1971–2010 period from German (DWD and Polish (IMGW-PIB meteorological stations, concerning both daily and 12 UTC data. The climate projections were carried out under various emission scenarios (SRES A1B, RCP2.6 and RCP8.5 within MPI-ESM-LR and ECHAM5 GCMs. Future conditions were analyzed for two periods: 2021–2050 (near future and 2071–2100 (far future and compared with the reference period 1971–2000. The thermal bioclimate was assessed with the use of the Universal Thermal Climate Index (UTCI. The Weather Suitability Index (WSI and Climate-Tourism/Transfer-Information-Scheme (CTIS were used for tourism-climate approaches. In the lowlands of the study area, the most convenient weather conditions for tourism and recreation are observed during the spring and autumn seasons (except intensive recreational activities. In the highest mountains, they are noticed in summer and from March to April due to the useful conditions for skiing. On the basis of CTIS, weather limitations for tourism are related mostly to sunshine and snow conditions for skiing in the mountain forelands. In the highest parts of the mountains, the most significant limitations are related to cold stress, precipitation, wind and sunshine conditions. Under A1B and RCP8.5 scenarios, an increase in the usefulness of weather conditions for most tourist activities in the cold season (November-April are

    Stock, Stephanie; Ihle, Peter; Simic, Dusan; Rupprecht, Christoph; Schubert, Ingrid; Lappe, Veronika; Kalbe, Elke; Tebest, Ralf; Lorrek, Kristina


    Elderly people with a non-German background are a fast growing population in Germany. Is administrative prevalence of dementia and uptake of nursing-home care similar in the German and non-German insured? Based on routine data, administrative prevalence rates for dementia were calculated for 2013 from a full census of data from one large sickness fund. Patients with dementia (PWD) were identified via ICD-10 codes (F00; F01; F03; F05; G30). Administrative prevalence of dementia was 2.67% in the study population; 3.06% in Germans, and 0.96% in non-Germans (p value citizenship, except in women aged 80-84 (17.2 vs. 15.4) and for men in the age groups 80-84 (16.5 vs. 14.2), 85-89 years (23.4 vs. 21.5), and above 90 years of age (32.3 vs. 26.3). Standardized to the population of all investigated insured, 31.4% of all Germans with dementia had no longterm care entitlement vs. 35.5% of all patients without German citizenship. Of German patients, 55.1% were institutionalized vs. 39.5% of all patients without German citizenship. There was a higher prevalence of dementia in the very old insured without German citizenship compared to those with German citizenship, especially in men. Non-Germans showed lower uptake of nursing home care compared to Germans. Additionally, Germans had slightly higher nursing care entitlements. It should be investigated further how much of the difference is due to underdiagnosis, cultural differences, or lack of adequate diagnostic work-up.

  1. The systemic changes to improve efficiency in Polish Primary Health Care

    Directory of Open Access Journals (Sweden)

    Tomasz Holecki


    Full Text Available Primary health care is an important part of any health care system. In highly developed countries it secures the population's most elementary health needs, with particular emphasis on preventive care and early intervention. Polish PHC model is currently undergoing a thorough transformation, associated with the need to adapt to standards designated based on the WHO's criteria, and with reference to the experience of other European countries. The paper describes the process of changes being carried out, in the context of previous experiences of reform relating to the sphere of organization, processes and efficiency. A review and systematization has been made, with regard to the undertaken activities in the field of deregulation and change of legal provisions, which are aimed at achieving the improvement of the efficiency of treatment and resource allocation. A set of recommendations based on expert's discourse have also been provided, with respect to future directions of Polish PHC transformation.

  2. Does Grammatical Gender Influence Perception? A Study of Polish and French Speakers

    Directory of Open Access Journals (Sweden)

    Haertlé Izabella


    Full Text Available Can the perception of a word be influenced by its grammatical gender? Can it happen that speakers of one language perceive an object to have masculine features, while speakers of another language perceive the same object to have feminine features? Previous studies suggest that this is the case, and also that there is some supra-language gender categorisation of objects as natural/feminine and artefact/masculine. This study was an attempt to replicate these findings on another population of subjects. This is the first Polish study of this kind, comparing the perceptions of objects by Polish- and French-speaking individuals. The results of this study show that grammatical gender may cue people to assess objects as masculine or feminine. However, the findings of some previous studies, that feminine features are more often ascribed to natural objects than artifacts, were not replicated.

  3. Chemical mechanical polishing (CMP) of sapphire (United States)

    Zhu, Honglin

    The concept of chemical mechanical polishing (CMP) was examined for finishing sapphire. In this study sapphire was used as a model system for oxide ceramics. The removal rates were determined by weight loss. Surface quality and structure were characterized with surface probe microscopy (SPM). Polishing experiments were designed to test the chemically modified surface layer. A series of abrasives with various hardnesses including mono-crystalline and polycrystalline diamond, alpha and gamma alumina, zirconia, ceria and silica were used. Diaspore was also evaluated. The results indicated that, with similar particle size and shape, harder abrasives do not necessarily cause faster material removal and better surface finish, and abrasives with hardness equal to or less than sapphire such as alpha alumina and gamma alumina achieved the best surface finish and efficient material removal. A hypothesis was proposed that the sapphire surface was modified by water to form a thin hydration laver with structure and hardness close to diaspore. Abrasives with a hardness between diaspore and sapphire polished the c-plane of sapphire with good surface finish and efficient removal. SPM indicated the hydration layer on the c-plane surface was about 1 nm thick. Removal rate and surface finish as a function of pH were also examined on c-plane sapphire with nano-alumina abrasives. The removal rate as a function of pH was compared to the solubility behavior of alumina. The results showed the deviation of pH from the lowest solubility pH for alumina (pH = 5) was a driving force for the surface reaction to form a hydration layer. The anisotropy of sapphire strongly affects removal rate and surface quality in CMP. The relationships among orientation. pH and abrasive were studied for sapphire with c (0001), a (11-20), and m (10-10) planes. Based on the results, the CMP process for sapphire includes chemical reaction of the surface to form a thin reaction layer that is softer than sapphire

  4. [German resuscitation registry : science and resuscitation research]. (United States)

    Gräsner, J-T; Seewald, S; Bohn, A; Fischer, M; Messelken, M; Jantzen, T; Wnent, J


    Sudden death due to cardiac arrest represents one of the greatest challenges facing modern medicine, not only because of the massive number of cases involved but also because of its tremendous social and economic impact. For many years, the magic figure of 1 per 1000 inhabitants per year was generally accepted as an estimate of the annual incidence of sudden death in the industrialized world, with a survival rate of 6 %. This estimate was based on large numbers of published reports of local, regional, national and multinational experience in the management of cardiac arrest. Measuring the global incidence of cardiac arrest is challenging as many different definitions of patient populations are used. Randomized controlled trials (RCT) provide insights into the value of specific treatments or treatment strategies in a well-defined section of a population. Registries do not compete with clinical studies, but represent a useful supplement to them. Surveys and registries provide insights into the ways in which scientific findings and guidelines are being implemented in clinical practice. However, as with clinical studies, comprehensive preparations are needed in order to establish a registry. This is all the more decisive because not all of the questions that may arise are known at the time when the registry is established. The German resuscitation registry started in May 2007 and currently more than 230 paramedic services and hospitals take part. More than 45,000 cases of out-of-hospital cardiac arrest and in-hospital cardiac arrest are included. With this background the German resuscitation registry is one of the largest databases in emergency medicine in Germany. After 5 years of running the preclinical care dataset was revised in 2012. Data variables that reflect current or new treatment were added to the registry. The postresuscitation basic care and telephone cardiopulmonary resuscitation (CPR) datasets were developed in 2012 and 2013 as well. The German

  5. Cultural events - does attendance improve health? Evidence from a Polish longitudinal study. (United States)

    Węziak-Białowolska, Dorota; Białowolski, Piotr


    Although there is strong advocacy for uptake of both the arts and creative activities as determinants of individual health conditions, studies evaluating causal influence of attendance at cultural events on population health using individual population data on health are scarce. If available, results are often only of an associative nature. In this light, this study investigated causative impact of attendance at cultural events on self-reported and physical health in the Polish population. Four recent waves (2009, 2011, 2013 and 2015) of the biennial longitudinal Polish household panel study, Social Diagnosis, were analysed. The data, representative for the Polish population aged over 16, with respect to age, gender, classes of place of residence and NUTS 2 regions, were collected from self-report questionnaires. Causative influence of cultural attendance on population health was established using longitudinal population representative data. To account for unobserved heterogeneity of individuals and to mitigate issues caused by omitted variables, a panel data model with a fixed effects estimator was applied. The endogeneity problem (those who enjoy good health are more likely to participate in cultural activities more frequently) was circumvented by application of instrumental variables. Results confirmed positive association between cultural attendance and self-reported health. However, in contrast to the often suggested positive causative relationship, such a link was not confirmed by the study. Additionally, no evidence was found to corroborate a positive impact from cultural attendance on physical health. Both findings were substantiated by augmentation in the longitudinal perspective and causal link. We showed the relation between attendance at cultural events and self-reported health could only be confirmed as associational. Therefore, this study provided little justification to encourage use of passive cultural participation as a measure of health promotion

  6. Asymmetric Mutual Social Perception of Austrians and Germans: A Social Identity Approach Assessing Implicit and Explicit Attitudes

    Directory of Open Access Journals (Sweden)

    Walter Renner


    Full Text Available Whereas Austrians tend to perceive Germans as "competent but cold", Germans tend to see Austrians as "incompetent but nice" in the sense of Fiske's Stereotype Content Model. With respect to the unequal distribution of power between Austria and Germany, which outnumbers Austria by approximately the tenfold population, Social Identity Theory (SIT predicts that Austrians will tend to devalue Germans, attempting to preserve their self-esteem and cultural identity, whereas Germans will perceive Austrians more positively. We tested this expectation with N = 31 Austrian and N = 49 German students at an Austrian university. Our hypotheses of asymmetrical mutual attitudes and massive devaluation of Germans by Austrians were confirmed by the Implicit Association Test, whereas on adjective lists as an explicit measure, Austrians described Germans more favourably, obviously out of a desire not to appear prejudiced. The results support SIT and have important implications for the development of Austrian academic education.

  8. Anglo-german – a colloquial language?

    Directory of Open Access Journals (Sweden)

    Rodica Teodora BIRIŞ


    Full Text Available In the last years more and more words from English entered in German language, which ledto the formation of a colloquial language called "Denglisch" from "Deutsch - German" and"Englisch - English". Denglisch differs from the Anglicisms through the fact that here are observedsyntactic and morphological rules of the German language, which proves the power of Germangrammar.In the article below we follow the areas where the colloquial language is used morefrequently and how it is used by German speakers. Denglisch is fought by the German linguists,who recommended the use of English words, only if there is not a similar term in German.

  9. Immobile Complex Verbs in Germanic

    DEFF Research Database (Denmark)

    Vikner, Sten


    Certain complex verbs in Dutch, German, and Swiss German do not undergo verb movement. The suggestion to be made in this article is that these ‘‘immobile'' verbs have to fulfill both the requirements imposed on complex verbs of the V° type (=verbs with non-separable prefixes) and the requirements...... imposed on complex verbs of the V* type (=verbs with separable prefixes). This results in such verbs being morphologically unexceptional, i.e., having a full set of forms but syntactically peculiar (‘‘immobile''), i.e., they can only occur in their base position. Any movement is incompatible with either...... frequent type with only one prefix-like part (e.g., German bauchreden/Dutch buikspreken ‘to ventriloquize'). This analysis will try to account not only for the data discussed in Haider (1993) and Koopman (1995) but also for the following: - why immobile verbs include verbs with only one prefix-like part...

  10. Plurilingualism and polish teenage learners of english

    Directory of Open Access Journals (Sweden)

    Agnieszka Otwinowska‑Kasztelanic


    Full Text Available Using several languages has become a norm for those who want to learn and work in the European Union. However, teaching for plurilingualism is also a challenge. The present paper first clarifies the notions of plurilingualism and multilingualism, then discusses the role of crosslinguistic similarity in language learning in the case of European languages. It also shows how lexical crosslinguistic similarity can be used in teaching typologically related and unrelated languages, and discusses the key factors in noticing such similarity. The research presented reports on examining and raising language awareness of Polish‑‑ English cognate vocabulary in the case of a group of Polish teenage learners of English. It presents the results of a small‑‑ scale study in quasi‑‑ experimental design, as well as qualitative research on the learners’ opinions and attitudes. Finally, the paper presents implications for language pedagogy and focuses on the fact that awareness raising may affect the learners’ plurilingual competence.

    Polish strains of canine parvovirus isolated between 1982 and 1993 were examined to determine the extent to which the virus has evolved antigenically and genetically over eleven years. Two CPV isolates obtained in Warsaw in 1982 and Pulawy in 1993, were examined using monoclonal antibody typing, restriction analysis and sequencing VP-2 protein gene. Five other isolates from Warsaw and Pulawy were tested with the panel of monoclonal antibodies specific to CPV-2, CPV-2a and common for canine parvovirus, feline panleukopenia virus and milk enteritis virus. Results of the studies demonstrated that all isolates tested represented CPV-2a antigenic type. Rapid antigenic strain replacement recorded by Parrish and Senda in the U.S.A and Japan was not confirmed in Poland. (author). 30 refs, 2 tabs.

  12. Attitudes of Polish Consumers Toward Experiential Marketing

    Directory of Open Access Journals (Sweden)

    Monika Skorek


    Full Text Available Purpose: The experience economy is a concept that can be defned as a new way of perceiving the market offer of an enterprise, focusing on the customer experience. Enterprises, both in the production and service industries, are becoming similar to one another on a massive scale, which makes it increasingly diffcult to stand out. The response to this can be to offer the consumer an unforgettable experience related to a product or service provided by a company. Methodology: This study analysed the results of qualitative research on the attitudes and opinions of Polish consumers on experience marketing. Results/fndings: The results showed that participants of the study were prepared to transition from the economy based on products or services to an economy based on experiences at a moderate level. They declared a willingness to participate in experiences offered by companies but at the same time focus on the cost and utility of them

  13. Droughts in historical times in Polish territory (United States)

    Limanowka, Danuta; Cebulak, Elzbieta; Pyrc, Robert; Doktor, Radoslaw


    Climate change is one of the key environmental, social and economical issues, and it is also followed by political consequences. Impact of climate conditions on countries' economy is increasingly recognized, and a lot of attention is given, both in the global scale and by the individual national governments. In years 2008-2010, at the Poland -Institute of Meteorology and Water Management-National Research Institute was realized the KLIMAT Project on Impact of climate change on environment, economy and society (changes, effects and methods of reducing them, conclusions for science, engineering practice and economic planning) No. POIG01-03-01-14-011/08. The project was financed by the European Union and Polish state budget in frame of Innovative Economy Operational Programme. A very wide range of research was carried out in the different thematic areas. One of them was "Natural disasters and internal safety of the country (civil and economical)." The problem of drought in Poland was developed in terms of meteorology and hydrology. "Proxy" Data Descriptions very often inform about dry years and seasons, hot periods without precipitation. Analysis of historical material allowed to extract the years that have experienced prolonged periods of high temperatures and rainfall shortages. Weather phenomenon defined as drought belongs to extreme events. This information was very helpful in the process of indexing and thus to restore the course and intensity of climatic elements in the past. The analysis covered the period from year 1000 to modern times. Due to the limited information from the period of 1000-1500 the authors focused primarily on the period from 1500 to 2010. Analysis of the collected material has allowed the development of a highly precise temporal structure of the possible occurrence of dry periods to Polish territory.

  14. Male suicide rates in German prisons and the role of citizenship. (United States)

    Radeloff, Daniel; Lempp, Thomas; Kettner, Mattias; Rauf, Amna; Bennefeld-Kersten, Katharina; Freitag, Christine M


    Prisoners are at a particularly high risk of suicide. In contrast to other psychosocial risk factors it remains unclear to what degree the risk of suicide differs between prisoners with local citizenship and foreigners. In order to provide more detailed information for suicide prevention in prisons, this study aims to compare suicide rates (SR) between these populations in German criminal custody. Based on a German national database of completed suicide in custody, suicides by prisoners were analysed and compared with epidemiological data of the prison population and the general population, stratified for German and foreign citizenship. Data analysis was adjusted for differences in the age distribution of both populations by calculating standard mortality ratios (SMR) for suicide. SR were higher in prisoners with German citizenship than those with foreign citizenship (SR = 76.5 vs. SR = 42.8, Pcitizenship was comparable in juvenile and adult prisoners, indicating its relevance to both the juvenile and adult detention systems. Imprisonment is associated with a substantially increased risk of suicide in both German and non-German citizens, a finding which needs to be taken into consideration by the justice system. The lower suicide risk in non-German citizens is independent of whether or not they are in custody.

  16. The German version of the Perceived Stress Scale - psychometric characteristics in a representative German community sample. (United States)

    Klein, Eva M; Brähler, Elmar; Dreier, Michael; Reinecke, Leonard; Müller, Kai W; Schmutzer, Gabriele; Wölfling, Klaus; Beutel, Manfred E


    The Perceived Stress Scale Cohen (J Health Soc Behav 24:385-96, 1983) is a widely and well-established self-report scale measuring perceived stress. However, the German version of the PSS-10 has not yet been validated. Thus, the purposes of this representative study were to psychometrically evaluate the PSS-10, and to provide norm values for the German population. The PSS-10 and standardized scales of depression, anxiety, fatigue, procrastination and life satisfaction were administered to a representative, randomly selected German community sample consisting of 1315 females and 1148 male participants in the age range from 14 to 90 years. The results demonstrated a good internal consistency and construct validity. Perceived stress was consistently associated with depression, anxiety, fatigue, procrastination and reduced life satisfaction. Confirmatory factor analysis revealed a bi-dimensional structure with two related latent factors. Regarding demographic variables, women reported a higher level of stress than men. Perceived stress decreased with higher education, income and employment status. Older and married participants felt less stressed than younger and unmarried participants. The PSS-10 is a reliable, valid and economic instrument for assessing perceived stress. As psychological stress is associated with an increased risk of diseases, identifying subpopulations with higher levels of stress is essential. Due to the dependency of the perceived stress level on demographic variables, particularly age and sex, differentiated norm values are needed, which are provided in this paper.

  17. Direct polishing of aluminum mirrors with higher quality and accuracy. (United States)

    Yin, Ziqiang; Yi, Zhang


    Diamond-turned aluminum mirrors have been widely used in modern optical systems. However, the machined surfaces have characteristic periodic tool marks, which contribute to reduced optical performance by creating effects such as scattering and distortion. This paper develops a new polishing technology to polish aluminum mirrors directly to remove tool marks and improve surface quality and surface accuracy. A Taguchi experiment was used to obtain optimal polishing conditions for reducing surface roughness, and computer-controlled optical surfacing technology was employed for form correction of aluminum mirrors.

  4. Study on the influence of the rotational speed of polishing disk on material removal in aspheric surface compliant polishing

    Directory of Open Access Journals (Sweden)

    Liyong Hu


    Full Text Available When a soft polishing tool is compressed on a stiff workpiece of curved surface, the contact area is a piece of the curved surface. In the process of aspheric surface polishing, the machining speed is always provided by the rotational speed of the spindle of a computer numerical control lathe. Yet, the polishing tool is usually made rotating to remove cutting scraps and broken abrasives from the contact area. The rotational speed of the polishing tool would change the distribution state of the relative speed in the whole contact area, and it would definitely change the volume of material removal in the surface of the workpiece. This article studies how the rotational speed of the polishing tool changes the distribution state of the relative speed in the whole contact area and material removal in the volume of the surface of the workpiece. The computing results show that the volume of material removal increases with the increase in both the rotational speed of polishing disk and the rotational speed of lathe spindle, but the polishing quality is totally not in this case.

  7. German urologists under national socialism. (United States)

    Krischel, Matthis


    The first full-time professorship for urology at a German university was established in 1937 and in 1942, a rare teaching qualification (Habilitation) for urology was granted, both at the prestigious Berlin University. At the same time, nearly a third of all physicians who worked in the field of urology were classified as "non-Aryan" according to Nazi race laws and were forced out of their profession and their homeland. Many of them committed suicide or, if they refused to flee, were murdered in concentration camps. German urologists also contributed to compulsory sterilization of men according to the "law for the prevention of hereditarily diseased offspring" between 1934 and 1945. Historical sources on the history of urology in Nazi Germany were reviewed and analyzed. These include textbooks and medical journals from the 1930s and 1940s, as well as files from different state and university archives. For urologists, the changing political environment in Germany after 1933 offered possibilities to assert their personal and professional interests. Unfortunately, in many cases, moral principles were thrown overboard, and physicians advanced their own careers and the specialty of urology at the expense of their patients and their Jewish colleagues. Under national socialism, German urologists backed Nazi health and race policies and in exchange gained further professionalization for their specialty, including university positions and increased independence from surgery. Only in recent years has this chapter of German urology's past become a topic of debate among members of the professional society.

  9. Skin picking in a non-clinical sample of young Polish adults. Prevalence and characteristics. (United States)

    Prochwicz, Katarzyna; Kałużna-Wielobób, Alina; Kłosowska, Joanna


    The aim of the study was to examine the prevalence and characteristics of skin picking behaviors in a sample of young Polish adults. Five hundred and thirty-four participants completed measurements of skin picking frequency and severity. They also retrospectively rated the intensity of affective states experienced before, during and after skin picking episodes. In total, 46.07% of the participants endorsed some forms of skin picking, and the prevalence of skin picking disorder (SPD) in the study sample amounted to 7.67%. The characteristics of skin picking episodes in young Polish adults were similar to those reported in previous studies conducted on different cultures. The results also showed that for the majority of individuals with skin picking, the intensity of particular emotions (i.e. fear, anxiety, guilt, shame, self-aversion, boredom, and sadness) decreased significantly in the period from before to after picking. Larger community studies are needed to assess the SPD prevalence in Polish general population. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available The term "economic culture" describes historically shaped elements in the general culture of population, concerning values recognized and desired by a particular community, relating to the management and to the economic system of the states. The most important economic cultural behaviors include: awareness of economic choices, attitudes and behaviors of economic choices, the rules of the economic game. There is a theory which assumes that the globalization of the economy will lead to the emergence of a single, common to the whole world culture through enculturation, which is defined as a gradual process of growing of the individual (or group into the culture or cultures through assimilation of cultural heritage of the surrounding community. More inculturation can be understood as a process of movement between different cultures come into contact and the transmission of cultural patterns. The article is an attempt at presenting the Polish economic culture against the European background and identifying the differences. It discusses the impact of national history and religion on the present shape of economic life, with particular regard to its negative aspects, i.e. the relatively high level of bribery and unemployment or the negative personal attitudes.

  13. Environmental risk assessment of Polish wastewater treatment plant activity. (United States)

    Kudłak, Błażej; Wieczerzak, Monika; Yotova, Galina; Tsakovski, Stefan; Simeonov, Vasil; Namieśnik, Jacek


    Wastewater treatment plants (WWTPs) play an extremely important role in shaping modern society's environmental well-being and awareness, however only well operated and supervised systems can be considered as environmentally sustainable. For this reason, an attempt was undertaken to assess the environmental burden posed by WWTPs in major Polish cities by collecting water samples prior to and just after wastewater release points. Both classical and biological methods (Microtox(®), Ostracodtoxkit F™ and comet assay) were utilized to assess environmental impact of given WWTP. Interestingly, in some cases, water quality improvement indicated as a toxicity decrement toward one of the bio-indicating organisms makes water worse for others in the systems. This fact is particularly noticeable in case of Silesian cities where heavy industry and high population density is present. It proves that WWTP should undergo individual evaluation of pollutant removal efficiency and tuned to selectively remove pollutants of highest risk to surrounding regional ecosystems. Biotests again proved to be an extremely important tool to fully assess the impact of environmental stressors on water bodies receiving effluents from WWTPs. Copyright © 2016 Elsevier Ltd.

  14. Unconventional therapists and their patients in Polish traditional folk medicine

    Directory of Open Access Journals (Sweden)

    Piątkowski Włodzimierz


    Full Text Available Folk medicine is a clearly distinct, comparatively homogeneous and closed system which has arisen from many centuries of isolation and self-sufficiency of the people of the Polish countryside. A feature of this special system involved tradition and relatively consistent illness behaviors, resistant to broader influences of the global society, despite the gradually growing role of modernization factors. An inherent feature of folk culture that impacted behaviors and attitudes of the rural population towards illness was the co-occurrence and overlapping of mystical-magical and religious elements. These applied both to the views on etiology, prevention, diagnosis and therapeutic treatment. Special functions in healing activities in the countryside were performed by the elderly. The matters related to health and illness were the province of the elderly as they were respected and revered for their life’s wisdom and life experience. The purpose of the article is to show the specificity of non-medical treatment in the context of social and cultural determinants, placing special emphasis on the role and importance of the elderly in exercising treatment roles.


    Arabas, Iwona; Asada, Shoji


    Present knowledge of the history of Ainu culture is owed in significant part to Polish Far-East researchers Bronisław Piłsudski (1866-1918) and Wacław Sieroszewski (1858-1945). They were both exiled to Siberia for their patriotic activity at the time where Poles struggled for independence. Bronisław Piłsudski is known for using glass photographic plates and wax recording cylinders for recording the already disappearing culture of the Ainu people. It is thanks to his research that we are able today to trace back the names of over 100 plants that had therapeutic, and as believed by Ainu, also magical power. The plants with the highest therapeutic significance had common characteristics: strong effects, intensive scent and stings. Nowadays, the Ainu people constitute an ethnic minority in Japan (population of over 20 000) and are supported by the Center for Ainu and Indigenous Studies at the Hokkaido University in Sapporo.

  16. Unattached fraction of radon progeny in Polish coal mines

    International Nuclear Information System (INIS)

    Skubacz, K.; Michalik, B.


    The system of the monitoring of the radiation hazard in Polish coal mines is based on the monitoring of the workplaces. This system works since 1989 in all coal mines. It gives a very good basis for further epidemiological investigation and assessment of the health detriment within the population of the mines as a result of the exposure for natural radiation. It is very important problem, due to the fact of the presence in the mines another factors, which probably have a synergetic effects on the respiratory tracts. As the routine instrument, a device called ALFA-31 sampling probe was developed in our laboratory. This device was accomplished to regular dust sampler and simultaneous measurements of dust content and potential alpha energy concentration of radon progeny are obligatory in all underground mines in Poland. But the microcyclone used a separator of the respirable fraction which causes the cut-off of unattached fraction of radon progeny, On the other hand measurements of the unattached fraction of short lived radon progeny play a very important role in the investigations of the adequate dose from this source of radiation hazard. During field experiments the use of the alpha spectroscopy system is necessary, while measurements are done not in the vacuum chambers but under normal pressure. It leads to situation, when particular peaks in alpha spectrum are very wide and interfere with other peaks of another alpha-emitting radionuclides. Such instrumentation was designed and completed, and a survey in several underground mines was performed. The analysis of the obtained results must be done very carefully; in other case it may cause a very big uncertainty of the result. In this paper a new approach to the analysis of the alpha spectra has been described. This approach can be used also in other applications of alpha spectroscopy, in which the analysis of energy of alpha peaks in spectrum is needed. The method of the analysis is based on a non-linear regression

  17. Effect of Polishing Systems on Surface Roughness and Topography of Monolithic Zirconia. (United States)

    Goo, C L; Yap, Auj; Tan, Kbc; Fawzy, A S


    This study evaluated the effect of different chairside polishing systems on the surface roughness and topography of monolithic zirconia. Thirty-five monolithic zirconia specimens (Lava PLUS, 3M ESPE) were fabricated and divided into five groups of seven and polished with the following: Group 1 (WZ)-Dura white stone followed by Shofu zirconia polishing kit; Group 2 (SZ)-Shofu zirconia polishing kit; Group 3 (CE)-Ceramiste porcelain polishers; Group 4 (CM)-Ceramaster porcelain polishers; and Group 5 (KZ)-Komet ZR zirconia polishers. All specimens were ground with a fine-grit diamond bur prior to polishing procedures to simulate clinical finishing. Baseline and post-polishing profilometric readings were recorded and delta Ra values (difference in mean surface roughness before and after polishing) were computed and analyzed using one-way analysis of variance and Scheffe post hoc test (pzirconia.

  18. Polish electoral geography and its methods

    Directory of Open Access Journals (Sweden)

    Zbigniew Rykiel


    Full Text Available Differences in the understanding of electoral geography between social sciences are discussed in the article. Main fields and spatial scales of Polish electoral geography are identified. Main methods of multidimensional statistics are discussed. A necessity of a proper choice, based on theories of voting behaviour, of explaning variables to statistical models are emphasised. Regression analysis indicates only a formal usefulness in electoral geography, for quantitative relationships between variables in the model can be evidenced, which may be meaningless not only essentially, but even statistically. The application of canonical analysis in electoral geography brought a methodological turning-point to the statistical approach. This method allowed to combine: (1 the foundation of the selection of input variables on theories of voting behaviour; (2 the analysis of dependence of the electoral results on socio-economic characteristics of areas; (3 an identification of electoral options; (4 a quantification of the role of the historical heritage in the contemporary voting behaviour; and (5 the analysis of the stability of the electoral space. A well grounded opinion was weakened about the general competitiveness of right- and left-wing parties in Poland’s political space. Parties with similar rather than different programmes compete in given areas. It was indicated that elections have only formal influence on the structure of Parliament while the electoral system is decisive. Electoral, including territorial, manipulations also play their part. The empirical analysis indicated that Poland’s political space is polarised between the right-wing-oriented areas of the south-eastern half of the country and the left-wing-oriented areas of the north-western half. The political competition between the left and the right operates merely on the national scale, while it is not reflected territorially.The quantification of the influence of the nineteenth

  2. Production of rare earth polishing powders in Russia

    International Nuclear Information System (INIS)

    Kosynkin, V.D.; Ivanov, E.N.; Kotrekhov, V.A.; Shtutza, M.G.; Grabko, A.I.


    Full text: Russia is a potent producer of polishing powders made of rare earth material presented as an extensive and well developed base. Considering the reserves, the facilities predisposition and the polishing agent (cerium dioxide) content the chief mineral source is loparite, apatite and monazite. The production of rare earth polishing powders is based on specially developed continuous technological processes, corrosion-proof equipment, ensuring a high and stable production quality. A special attention is paid to the radiation safety of the powders. The initial material for the rare earth polishing powders based on loparite is the fusion cake of rare earth chlorides obtained at that mineral chlorination. The technology of the polishing powder production from the REE fusion cake includes the following stages: dissolution of the REE fusion cake chlorides; - thorough cleaning of the REE fusion cake chlorides from radioactive and non-rare-earth impurities; chemical precipitation of REE carbonates, obtaining middlings with proper material and granulometric composition, thermal treatment of precipitated carbonates followed with the operations of drying and roasting; classification of roasted oxides, obtaining end products - polishing powders. The production of fluorine-containing powders includes the stage of their fluorination after the stage of carbonate precipitation. The stabilizing doping can be introduced both into the middlings during one of the technological process of powders manufacturing and into the end product. Rare earth polishing powders are manufactured in Russia by the Share Holding Company 'Chepetz Mechanical Plant' (ChMP Co.), the city of Glasov. The plant produces a number of polishing materials, such as; polishing powder Optinol, containing at least 50% by mass of cerium dioxide, used in the mass production of optical and other articles; polishing powder Optinol-10 with doping to improve the sedimentary and aggregate stability of the solid phase

    Highlights: • Process optimisation for laser polishing novel 3D printed SS316L parts. • Evaluating the effects of key polishing parameters on SS316L surface roughness. • Detailed spectroscopic analysis of oxide layer formation due to laser polishing. • Comparative surface integrity analysis of SS parts polished in air and argon. • A maximum reduction in roughness of over 94% achieved at optimised polishing settings. - Abstract: Laser polishing of various engineered materials such as glass, silica, steel, nickel and titanium alloys, has attracted considerable interest in the last 20 years due to its superior flexibility, operating speed and capability for localised surface treatment compared to conventional mechanical based methods. The paper initially reports results from process optimisation experiments aimed at investigating the influence of laser fluence and pulse overlap parameters on resulting workpiece surface roughness following laser polishing of planar 3D printed stainless steel (SS316L) specimens. A maximum reduction in roughness of over 94% (from ∼3.8 to ∼0.2 μm S{sub a}) was achieved at the optimised settings (fluence of 9 J/cm{sup 2} and overlap factors of 95% and 88–91% along beam scanning and step-over directions respectively). Subsequent analysis using both X-ray photoelectron spectroscopy (XPS) and glow discharge optical emission spectroscopy (GDOES) confirmed the presence of surface oxide layers (predominantly consisting of Fe and Cr phases) up to a depth of ∼0.5 μm when laser polishing was performed under normal atmospheric conditions. Conversely, formation of oxide layers was negligible when operating in an inert argon gas environment. The microhardness of the polished specimens was primarily influenced by the input thermal energy, with greater sub-surface hardness (up to ∼60%) recorded in the samples processed with higher energy density. Additionally, all of the polished surfaces were free of the scratch marks, pits, holes

  10. Stem subsidence of polished and rough double-taper stems (United States)

    Yamada, Kengo; Hirosaki, Kenichi; Takano, Masahiro; Matsumoto, Tadami


    Background and purpose Many clinical reports have indicated that polished hip stems show better clinical results than rough stems of the same geometry. It is still unknown, however, what the mechanical effects are of different surface finishes on the cement at the cement-bone interface. We compared mechanical effects in an in vitro cemented hip arthroplasty model. Methods Two sizes of double-taper polished stems and matt-processed polished stems (rough stems) were fixed into composite femurs. A 1-Hz dynamic load was applied to the stems for 1 million cycles. An 8-h no-load period was set after every 16 h of load. Stem subsidence within the cement, and compressive force and horizontal cement creep at the cement-bone interface, were measured. Results Compared to rough stems, stem subsidence, compressive force and cement creep for polished stems were a maximum of 4, 12, and 7-fold greater, respectively. There was a strong positive correlation between stem subsidence and compressive force for polished stems. In contrast, a strong negative correlation was found between stem subsidence and compressive force for rough stems. There was also a statistically significant relationship between compressive force on the cement and cement creep for the polished stems, but no significant relationship was found for rough stems. Interpretation This is the first evidence that different surface finishes of stems can have different mechanical effects on the cement at the cement-bone interface. Stem subsidence in polished stems resulted in compressive force on the cement and cement creep. The mechanical effects that polished taper stems impart on cement at the cement-bone interface probably contribute to their good long-term fixation and excellent clinical outcome. PMID:19421909

    Ergücü, Zeynep; Türkün, L Sebnem; Aladag, Akin


    This study compared the color changes of five novel resin composites polished with two one-step polishing systems when exposed to coffee solution. The resin composites tested were Filtek Supreme XT, Grandio, CeramX, Premise and Tetric EvoCeram. A total of 150 discs (30/resin composites, 10 x 2 mm) were fabricated. Ten specimens/resin composites cured under Mylar strips served as the control. The other samples were polished with PoGo and OptraPol discs for 30 seconds using a slow speed handpiece and immersed in coffee (Nescafé) for seven days. Color measurements were made with Vita Easyshade at baseline and after one and seven days. Repeated Measures ANOVA and Bonferroni tests were used for statistical analyses (pGrandio, there were no significant differences between the Mylar and PoGo groups, while the most stain resistant surfaces were attained with OptraPol. Removing the outermost resin layer by polishing procedures is essential to achieving a stain resistant, more esthetically stable surface. One-step polishing systems can be used successfully for polishing nanocomposites.

  16. Factors influencing the surface quality of polished tool steels

    International Nuclear Information System (INIS)

    Rebeggiani, S; Rosén, B-G


    Today’s demands on surface quality of moulds for injection moulding of plastic components involve no/low defect contents and roughness levels in the nm-range for high gloss applications. Material properties as well as operating conditions influence the mould finish, and thus the final surface of moulded products. This paper focuses on how particle content and different polishing strategies influence final surface qualities of moulds. Visual estimations of polished tool steel samples were combined with non-contact 3D-surface texture analysis in order to correlate traditional assessments to more quantitative methods, and to be able to analyse the surfaces at nanometre-level. It was found that steels with a lower proportion of particles, like carbides and oxides, gave rise to smoother polished surfaces. In a comparative study of polishers from different polishing shops, it was found that while different surface preparation strategies can lead to similar final roughness, similar preparation techniques can produce high-quality surfaces from different steel grades. However, the non-contact 3D-surface texture analysis showed that not all smooth polished surfaces have desirable functional topographies for injection moulding of glossy plastic components. (paper)

  17. Advanced method for the characterization of polishing suspensions (United States)

    Trum, Christian J.; Sitzberger, Sebastian; Rascher, Rolf


    The industrial production of components for applications in the area of precision optics has a long-standing tradition in Germany. As in almost all branches of industry, the external circumstances, processes and products have changed over time. Large lots are becoming less frequent and the demand for special components is growing. In order to meet these requirements, it is necessary to adapt the production processes quickly and flexibly. In the field of chemo-mechanical polishing (CMP), this means that in addition to the process parameters such as speed, pressure and feed, the task-specific adaptation of suspension and polishing pad carriers gain in importance. Along with these changes, it is becoming increasingly important to compare and evaluate the properties of the various polishing suspensions. The procedures according to DIN 58750-3 and DIN 58750-4 are suitable for this purpose. Due to the clearly defined procedures and the constant boundary conditions, different suspensions can be compared and evaluated. The study presented here shows that this method can also lead to misinterpretations. Known relationships, such as the influence of the polishing pad, the concentration of the suspension and the influence of the processed materials play an important role. An extension of the procedure of DIN 58750-3 for the test of a polishing agent can help in a task-specific characterization of polishing slurries.

  18. [German Urological Associations under National Socialism]. (United States)

    Krischel, M; Moll, F; Fangerau, H


    The Deutsche Gesellschaft für Urologie (German Urological Association), established in 1907, was a German-Austrian medical society in which Jewish physicians held important positions. When the Nazis seized power in 1933, the Austrian Hans Rubritius was president of the society. The non-German presidency and the exclusion of Jewish colleagues from the professional society and medical practice led to a halt of the society's activities. At the same time in the mid 1930s, German urologists founded the Gesellschaft Reichsdeutscher Urologen (Association of Reichs-German Urologists) whose members aligned themselves with Nazi health policies and in turn received professional and personal benefits.

  20. Polish university as an (unattractive potential employer

    Directory of Open Access Journals (Sweden)

    Baruk, Agnieszka Izabela


    Full Text Available The article presents issues associated with the reasons for the fact that young potential employees are not interested in starting work at Polish universities. The article is theoretical-empirical in character. The theoretical part highlights the importance of a situation in which an entity is regarded as an attractive employer, which allows attracting the best employees. Particular attention is paid to the fact that a university needs to build its image as an employer, which results from its characteristics. The article strives to achieve three research goals, among others, identifying the reasons why respondents are not interested in starting work at a university and arranging these reasons hierarchically. Two research hypotheses were subject to preliminary verification: H1 – the main reason for the unwillingness to start work at a university are financial aspects; H2 – the main reason for the unwillingness to start work at a university are the aspects of prestige. The data collected in course of primary research were subject to quantitative analysis based on the method of average assessment analysis and the method of factor analysis. Their results show that the respondents were not interested in work at a university mainly because they wanted to test the knowledge and skills acquired during studies in other branches. At the same time, the aspects of finances and prestige didn’t play a major role. Thus, in case of the surveyed sample of respondents both research hypotheses have to be recognized as untrue.

    Full Text Available Solutions in the field of ecological architecture appear more and more often in Poland. There are two approaches to eco-design: high-tech and low-tech. High-tech focuses on the use of the latest technological solvings. These means are often used in newly designed commercial buildings, such as the first Polish office building which uses passive technology, built in Katowice, in Euro-Centrum Science and Technology Park. It is intended especially for companies focusing on energy observance issues. Low-tech is usually used in small-scale buildings (for example a cottage in Jartypory village, and is focused on the use of inexpensive, traditional technologies and the daily conscious management of natural resources. Thinking about the impact on the environment and principles of sustainable development is also present in urban planning. In Siewierz, near Katowice, Poland’s first eco-village is being built, with full infrastructure, high-quality residential buildings, shops, offices and hotels. The range of applied solutions will allow residents for the economical exploitation of these buildings.

    Directory of Open Access Journals (Sweden)

    Ziębik Andrzej


    Full Text Available Basing on the first and second law of thermodynamics the fundamental trends in the Polish energy policy are analysed, including the aspects of environmental protection. The thermodynamical improvement of real processes (reduction of exergy losses is the main way leading to an improvement of the effectivity of energy consumption. If the exergy loss is economically not justified, we have to do with an error from the viewpoint of the second law analysis. The paper contains a thermodynamical analysis of the ratio of final and primary energy, as well as the analysis of the thermo-ecological cost and index of sustainable development concerning primary energy. Analyses of thermo-ecological costs concerning electricity and centralized heat production have been also carried out. The effect of increasing the share of high-efficiency cogeneration has been analyzed, too. Attention has been paid to an improved efficiency of the transmission and distribution of electricity, which is of special importance from the viewpoint of the second law analysis. The improvement of the energy effectivity in industry was analyzed on the example of physical recuperation, being of special importance from the point of view of exergy analysis.

  3. Marketing Globalisation – Polish Market Experience

    Directory of Open Access Journals (Sweden)

    Robert Nowacki


    Full Text Available The beginning of the 21st century has been yielded with an acceleration of transformations occurring in economies of the whole world. These changes relate to all the areas of economic life functioning. The most important manifestation thereof is a reinforcement of competitive phenomena. Among the most important reasons for such a state of affairs, there is mentioned globalisation. The course of its processes forces the organisation operating in the market to undertake adaptive actions. One of them is reorientation of marketing activities. The need to modify the previous marketing concepts results, first of all, from far reaching alterations in the sphere of consumption, just triggered by globalisationís impact. These trends are noticed in all the markets, also in the Polish one. The foreign enterprises operating in it more and more often use the concept of global marketing. This makes us to have reflection on what is the real effectiveness of such actions and what are the possibilities to form oneís competitive position owing to that. The article constitutes an attempt to provide answers to these questions.

  4. Automated visual inspection for polished stone manufacture (United States)

    Smith, Melvyn L.; Smith, Lyndon N.


    Increased globalisation of the ornamental stone market has lead to increased competition and more rigorous product quality requirements. As such, there are strong motivators to introduce new, more effective, inspection technologies that will help enable stone processors to reduce costs, improve quality and improve productivity. Natural stone surfaces may contain a mixture of complex two-dimensional (2D) patterns and three-dimensional (3D) features. The challenge in terms of automated inspection is to develop systems able to reliably identify 3D topographic defects, either naturally occurring or resulting from polishing, in the presence of concomitant complex 2D stochastic colour patterns. The resulting real-time analysis of the defects may be used in adaptive process control, in order to avoid the wasteful production of defective product. An innovative approach, using structured light and based upon an adaptation of the photometric stereo method, has been pioneered and developed at UWE to isolate and characterize mixed 2D and 3D surface features. The method is able to undertake tasks considered beyond the capabilities of existing surface inspection techniques. The approach has been successfully applied to real stone samples, and a selection of experimental results is presented.

  5. Study on chemical mechanical polishing of silicon wafer with megasonic vibration assisted. (United States)

    Zhai, Ke; He, Qing; Li, Liang; Ren, Yi


    Chemical mechanical polishing (CMP) is the primary method to realize the global planarization of silicon wafer. In order to improve this process, a novel method which combined megasonic vibration to assist chemical mechanical polishing (MA-CMP) is developed in this paper. A matching layer structure of polishing head was calculated and designed. Silicon wafers are polished by megasonic assisted chemical mechanical polishing and traditional chemical mechanical polishing respectively, both coarse polishing and precision polishing experiments were carried out. With the use of megasonic vibration, the surface roughness values Ra reduced from 22.260nm to 17.835nm in coarse polishing, and the material removal rate increased by approximately 15-25% for megasonic assisted chemical mechanical polishing relative to traditional chemical mechanical polishing. Average Surface roughness values Ra reduced from 0.509nm to 0.387nm in precision polishing. The results show that megasonic assisted chemical mechanical polishing is a feasible method to improve polishing efficiency and surface quality. The material removal and finishing mechanisms of megasonic vibration assisted polishing are investigated too. Copyright © 2017 Elsevier B.V. All rights reserved.

  6. The impact of forced displacement in World War II on mental health disorders and health-related quality of life in late life - a German population-based study. (United States)

    Freitag, Simone; Braehler, Elmar; Schmidt, Silke; Glaesmer, Heide


    Long-term effects of World War II experiences affect psychological and physical health in aged adults. Forced displacement as a traumatic event is associated with increased psychological burden even after several decades. This study investigates the contribution of forced displacement as a predictor for mental health disorders and adds the aspect of health-related quality of life (QoL). A sample of 1,659 German older adults aged 60-85 years was drawn from a representative survey. Post-traumatic stress disorder (PTSD), somatoform symptoms, depressive syndromes, and health-related QoL were assessed as outcome variables. Chi-square and t-test statistics examined differences between displaced and non-displaced people. Logistic regression analyses were performed to examine the impact of forced displacement on mental health disorders and QoL. Displaced people reported higher levels of PTSD, depressive and somatoform symptoms, and lower levels of health-related QoL. Displacement significantly predicted PTSD and somatoform symptoms in late life, but not depressive disorders. Health-related QoL was predicted by forced displacement and socio-demographic variables. Forced displacement is associated with an elevated risk for PTSD and somatoform symptoms and lowered health-related QoL in aged adults. Its unique impact declines after including socio-demographic variables. Long-term consequences of forced displacement need further investigations and should include positive aspects in terms of resilience and protective coping strategies.

    Kiedrowski, Mirosław; Mróz, Andrzej; Gajewska, Danuta; Nurzyński, Paweł; Deptała, Andrzej


    Celiac disease affects about 1% of the population. Since most Polish households have a broadband Internet connection, a lot of people use web resources to learn about health and disease. YouTube service ( offers a lot of videos concerning celiac disease. However, the credibility of the Polish videos available on YouTube and concerning celiac disease has never been analyzed. The aim of the study was to determine whether the YouTube service offers valuable content for Polish people affected by celiac disease. One hundred and fifty-four unique videos devoted to celiac disease and available in the Polish language were identified and critically assessed. Each video was categorized due to its topic(s), and evaluated for its credibility by two independent researchers. In general, 127 (82.5%) videos were found to be credible. The most credible categories of content presented organizations and events related to celiac disease/celiac society, followed by culinary recipes (100.0, 100.0, and 95.6% of credible videos, respectively). The least trustworthy categories were devoted to pathobiology and advertisements (55.6 and 54.3% of credible videos, respectively). YouTube service can serve as a supplementary source of knowledge for people affected by celiac disease, after careful selection of trustworthy content.

  10. Alternative technique for class V resin composite restorations with minimum finishing/polishing procedures. (United States)

    Perez, Cesar Reis


    Class V restorations are a very common occurrence in clinics. Some reasons include an increase in non-carious cervical lesions (NCCL), root caries and the elderly population. Unfortunately, Class V restorations also represent one of the less durable types of restorations and have a high index of loss of retention, marginal excess and secondary caries. Some causes for these problems include difficulties in isolation, insertion, contouring, finishing and polishing procedures. This technique demonstrates an alternative isolation and insertion method using photocured gingival barrier in association with a flowable resin and hybrid resin composite to recreate the gingival wall with minimum or no excess.

  12. Effect of various polishing systems on the surface roughness and phase transformation of zirconia and the durability of the polishing systems. (United States)

    Park, Chan; Vang, Mong-Sook; Park, Sang-Won; Lim, Hyun-Pil


    Although many systems are used to polish zirconia, a comparison of the performance of zirconia and feldspathic porcelain polishing systems is lacking. The purpose of this in vitro study was to compare the effects of 3 polishing systems on surface roughness, zirconia phase transformation, and durability of the polishing systems when applied to zirconia and feldspathic porcelain. Three polishing systems were evaluated: Z1, a zirconia polishing system; Z2, a zirconia polishing system, and F1, a feldspathic porcelain polishing system. Three ceramic systems were evaluated: PR and ZM zirconia specimens (diameter 15 mm, height 2 mm; 23 specimens each) and CB feldspathic porcelain specimens of the same size (15 specimens). A rough surface was created on the 3 types of specimens (15 specimens each) to model an occlusal adjustment under the same conditions. Polishing was carried out with the 3 polishing systems for 2 minutes each. Surface roughness was measured with a 3-dimensional (3D) optical profiler. The surface was also observed with a scanning electron microscopy. X-ray diffraction analysis was performed for 8 PR or ZM zirconia specimens polished by using the Z1 and Z2 systems for 8 minutes to evaluate the phase transformation of zirconia before, during, and after polishing. These specimens were compared and analyzed for phase transformation that might have occurred during the polishing of the specimens. After finishing the surface roughness experiment and the phase transformation experiment, the volumes of the polishers were measured with a 3D volume scanner and compared with those before the experiments to evaluate the durability of the polishing system. A statistical analysis of all data was performed using 2-way ANOVA and the Tukey honest significant difference test (α=.05). The 2 zirconia polishing systems (Z1, Z2) created a significantly (Pzirconia specimens for 8 minutes, the maximum percentages of monoclinic phase increased by 0.03% in the Z1 system and by 0

  14. Antagonist wear by polished zirconia crowns. (United States)

    Hartkamp, Oliver; Lohbauer, Ulrich; Reich, Sven

    The aim of this in vivo study was to measure antagonist wear caused by polished monolithic posterior zirconia crowns over a 24-month period using the intraoral digital impression (IDI) technique. Thirteen zirconia crowns were placed in nine patients. The crowns and adjacent teeth were captured using an intraoral scanner (Lava C.O.S.). The corresponding antagonist teeth and the respective neighboring teeth were also scanned. Scanning was performed immediately after the restoration (baseline) as well as 12 and 24 months after crown placement. Geomagic Qualify software was used to superimpose the follow-up data sets onto the corresponding baseline data set, identify wear sites, and measure maximum vertical height loss in each individual wear site. Overall antagonist wear was then determined as the mean of wear rates measured in all of the individual antagonist units. In addition, wear rates in enamel and ceramic antagonists were analyzed as part of the scope of this study. The maximum mean wear with standard deviation (SD) in the overall sample with a total of nine patients, 13 antagonist units, and 98 evaluable wear sites was 86 ± 23 µm at 12 months, and 103 ± 39 µm at 24 months. The maximum mean wear in the enamel antagonist subgroup was 87 ± 41 µm at 12 months, and 115 ± 71 µm at 24 months; and in the ceramic antagonist subgroup 107 ± 22 µm at 12 months, and 120 ± 27 µm at 24 months. The wear rates determined in this study are comparable to those of existing studies. The IDI technique of wear analysis can be carried out in a practical manner and produces useful results.

  15. Germanium content in Polish hard coals

    Directory of Open Access Journals (Sweden)

    Makowska Dorota


    Full Text Available Due to the policy of the European Union, it is necessary to search for new sources of scarce raw materials. One of these materials is germanium, listed as a critical element. This semi-metal is widely used in the electronics industry, for example in the production of semiconductors, fibre optics and solar cells. Coal and fly ash from its combustion and gasification for a long time have been considered as a potential source of many critical elements, particularly germanium. The paper presents the results of germanium content determination in the Polish hard coal. 23 coal samples of various coal ranks were analysed. The samples were collected from 15 mines of the Upper Silesian Coal Basin and from one mine of the Lublin Coal Basin. The determination of germanium content was performed with the use of Atomic Absorption Spectrometry with Electrothermal Atomization (GFAAS. The investigation showed that germanium content in the analysed samples was at least twice lower than the average content of this element in the hard coals analysed so far and was in the range of 0.08 ÷ 1.28 mg/kg. Moreover, the content of Ge in the ashes from the studied coals does not exceed 15 mg/kg, which is lower than the average value of Ge content in the coal ashes. The highest content of this element characterizes coals of the Lublin Coal Basin and young coals type 31 from the Vistula region. The results indicate a low utility of the analysed coal ashes as a source of the recovery of germanium. On the basis of the analyses, the lack of the relationship between the content of the element and the ash content in the tested coals was noted. For coals of the Upper Silesian Coal Basin, the relationship between the content of germanium in the ashes and the depth of the seam was observed.

  16. Studies on polishing of Ti and Ag-Pd-Cu-Au alloy with five dental abrasives. (United States)

    Hirata, T; Nakamura, T; Takashima, F; Maruyama, T; Taira, M; Takahashi, J


    Titanium (Ti) and Ag-Pd-Cu-Au alloy were examined for their polishing behaviour by conducting manually controlled polishing tests using five dental abrasives [carborundum point (CR) and silicone points (R1 and R2)] driven by a high torque micromotor with rotational speeds ranging from 2000 to 15 000 r.p.m. Polishing of Ti resulted in less volume of removal upon polishing, a rougher surface and larger loss of abrasives, compared with polishing of Ag-Pd-Cu-Au alloy. Polishing of Ti with a rotational speed of 15 000 r.p.m. led to the largest volume of removal upon polishing, whilst that of 10 000 r.p.m. produced the optimal volume for Ag-Pd-Cu-Au alloy. It was concluded that Ti was much more difficult to polish, requiring special care (e.g. frequent exchange of abrasives). Development of new abrasives for polishing Ti is required.

  17. The study of optimization on process parameters of high-accuracy computerized numerical control polishing (United States)

    Huang, Wei-Ren; Huang, Shih-Pu; Tsai, Tsung-Yueh; Lin, Yi-Jyun; Yu, Zong-Ru; Kuo, Ching-Hsiang; Hsu, Wei-Yao; Young, Hong-Tsu


    Spherical lenses lead to forming spherical aberration and reduced optical performance. Consequently, in practice optical system shall apply a combination of spherical lenses for aberration correction. Thus, the volume of the optical system increased. In modern optical systems, aspherical lenses have been widely used because of their high optical performance with less optical components. However, aspherical surfaces cannot be fabricated by traditional full aperture polishing process due to their varying curvature. Sub-aperture computer numerical control (CNC) polishing is adopted for aspherical surface fabrication in recent years. By using CNC polishing process, mid-spatial frequency (MSF) error is normally accompanied during this process. And the MSF surface texture of optics decreases the optical performance for high precision optical system, especially for short-wavelength applications. Based on a bonnet polishing CNC machine, this study focuses on the relationship between MSF surface texture and CNC polishing parameters, which include feed rate, head speed, track spacing and path direction. The power spectral density (PSD) analysis is used to judge the MSF level caused by those polishing parameters. The test results show that controlling the removal depth of single polishing path, through the feed rate, and without same direction polishing path for higher total removal depth can efficiently reduce the MSF error. To verify the optical polishing parameters, we divided a correction polishing process to several polishing runs with different direction polishing paths. Compare to one shot polishing run, multi-direction path polishing plan could produce better surface quality on the optics.

  19. Infestation of Polish Agricultural Soils by Plasmodiophora Brassicae Along The Polish-Ukrainian Border

    Directory of Open Access Journals (Sweden)

    Jędryczka Małgorzata


    Full Text Available There has been a rapid, worldwide increase in oilseed rape production that has resulted in enormous intensification of oilseed rape cultivation, leading to tight rotations. This in turn, has caused an accumulation of pests as well as foliar and soil-borne diseases. Recently, clubroot has become one of the biggest concerns of oilseed rape growers. Clubroot is caused by the soil-borne protist Plasmodiophora brassicae Woronin. The pathogen may be present in groundwater, lakes, and irrigation water used in sprinkling systems. It can be easily transmitted from one field to another not only by water, but also by soil particles and dust transmitted by wind and on machinery. The aim of our overall study was to check for P. brassicae infestation of Polish agricultural soils. This paper presents the 2012 results of a study performed along the Polish-Ukrainian border in two provinces: Lublin (Lubelskie Voivodeship and the Carpathian Foothills (Podkarpackie Voivodeship, in south-east Poland. Monitoring was done in 11 counties, including nine rural and two municipal ones. In total, 40 samples were collected, out of which 36 were collected from fields located in rural areas and four from municipal areas, with two per municipal region. Each sample was collected at 8-10 sites per field, using a soil auger. The biotest to detect the presence of P. brassicae was done under greenhouse conditions using seedlings of the susceptible Brassicas: B. rapa ssp. pekinensis and the Polish variety of oilseed rape B. napus cv. Monolit. Susceptible plants grown in heavily infested soils produced galls on their roots. A county was regarded as free from the pathogen, if none of the bait plants became infected. The pathogen was found in three out of 40 fields monitored (7.5% in the Carpathian Foothill region. The fields were located in two rural counties. The pathogen was not found in Lublin province, and was also not detected in any of the municipal counties. The detection with

    Full Text Available This in vitro study evaluated the effect of polishing after 1-day storage in water on the gap-formation around a Class V and Class I restorations, using a resin-modified glass–ionomer and a conventional glass–ionomer materials. The study also examined the gap-formation in another two different cervical restorations, a cervical cavity: incisally bordered by enamel and cervically by dentin and a root surface cavity of these restorative materials, which may be effects of this polishing procedure. This study evaluated the effects of delayed versus immediate polishing to permit maturation on: (1 interfacial gap-formation around resin-modified (RMGIC and conventional (CGIC in three types of cervical restorations, (2 interfacial gap-formation around highly viscous conventional glass–ionomer cement (HCGIC in Class I restorations. After polishing procedure, either: (i immediately (3 or 6 min after setting or (ii after 24 h storage, the maximum the restored teeth were sectioned in a mesio-distal direction through the center of the restorations. The presence or absence of interfacial-gaps was measured at 14 points (each 0.5-mm apart along the cavity restoration interface. For various restorative cases, significant differences (p < 0.05 in gap-width or gap-incidence, were observed between polishing (i immediately and (ii after 1-day storage.

  1. Nail polish as a source of exposure to triphenyl phosphate. (United States)

    Mendelsohn, Emma; Hagopian, Audrey; Hoffman, Kate; Butt, Craig M; Lorenzo, Amelia; Congleton, Johanna; Webster, Thomas F; Stapleton, Heather M


    Triphenyl phosphate (TPHP) is primarily used as either a flame retardant or plasticizer, and is listed as an ingredient in nail polishes. However, the concentration of TPHP in nail polish and the extent of human exposure following applications have not been previously studied. We measured TPHP in ten different nail polish samples purchased from department stores and pharmacies in 2013-2014. Concentrations up to 1.68% TPHP by weight were detected in eight samples, including two that did not list TPHP as an ingredient. Two cohorts (n=26 participants) were recruited to assess fingernail painting as a pathway of TPHP exposure. Participants provided urine samples before and after applying one brand of polish containing 0.97% TPHP by weight. Diphenyl phosphate (DPHP), a TPHP metabolite, was then measured in urine samples (n=411) and found to increase nearly seven-fold 10-14h after fingernail painting (pexposure, ten participants also painted their nails and painted synthetic nails adhered to gloves on two separate occasions, and collected urine for 24h following applications. Urinary DPHP was significantly diminished when wearing gloves, suggesting that the primary exposure route is dermal. Our results indicate that nail polish may be a significant source of short-term TPHP exposure and a source of chronic exposure for frequent users or those occupationally exposed.

  2. Terminologia anatomica in the past and the future from perspective of 110th anniversary of Polish Anatomical Terminology. (United States)

    Gielecki, J; Zurada, A; Osman, N


    Professional terminology is commonplace, particularly in the fields of mathematics, medicine, veterinary and natural sciences. The use of the terminology can be international, as it is with Anatomical Terminology (AT). In the early age of modern education, anatomists adopted Latin as the international language for AT. However, at the end of the 20th century, the English language became more predominant around the world. It can be said that the AT is a specific collection of scientific terms. One of the major flaws in early AT was that body structures were described by varying names, while some of the terms was irrational in nature, and confusing. At this time, different international committees were working on preparing a unified final version of the AT, which in the end consisted of 5,640 terms (4,286 originally from the Basle Nomina Anatomica, BNA). Also, each country wanted to have its own nomenclature. In order to accomplish this, each country based their nomenclature on the international AT, and then translated it into their own language. The history of the Polish Anatomical Terminology (PAT) is unique, and follows the events of history. It was first published in 1898, at a time when its neighbours partitioned the territory of Poland. During 150 years, the Polish culture and language was under the Russification and Germanization policy. It is important to note, that even with such difficult circumstances, the PAT was the first national AT in the world. The PAT was a union of the accepted first BNA in Latin and the original Polish anatomical equivalents. This union formed the basis for theoretical and clinical medicine in Poland.

    Daniel Radeloff

    Full Text Available Prisoners are at a particularly high risk of suicide. In contrast to other psychosocial risk factors it remains unclear to what degree the risk of suicide differs between prisoners with local citizenship and foreigners. In order to provide more detailed information for suicide prevention in prisons, this study aims to compare suicide rates (SR between these populations in German criminal custody.Based on a German national database of completed suicide in custody, suicides by prisoners were analysed and compared with epidemiological data of the prison population and the general population, stratified for German and foreign citizenship. Data analysis was adjusted for differences in the age distribution of both populations by calculating standard mortality ratios (SMR for suicide.SR were higher in prisoners with German citizenship than those with foreign citizenship (SR = 76.5 vs. SR = 42.8, P<0.01. This association was not specific to the prison population, as the higher SR in citizens compared to non-citizens (SR = 19.3 vs. SR = 9.0, P<0.01 were also found in the general population. The association between prison suicide and citizenship was comparable in juvenile and adult prisoners, indicating its relevance to both the juvenile and adult detention systems.Imprisonment is associated with a substantially increased risk of suicide in both German and non-German citizens, a finding which needs to be taken into consideration by the justice system. The lower suicide risk in non-German citizens is independent of whether or not they are in custody.

  4. The Polish Interventional Cardiology TAVI Survey (PICTS): adoption and practice of transcatheter aortic valve implantation in Poland (United States)

    Parma, Radosław; Dąbrowski, Maciej; Ochała, Andrzej; Witkowski, Adam; Dudek, Dariusz; Siudak, Zbigniew


    Introduction Few studies have assessed the development of transcatheter aortic valve implantation (TAVI) in Poland since its introduction in 2008, and data on current TAVI activity or practice are missing. Aim To assess the dynamics of TAVI adoption in Poland and to detect differences among Polish centres in TAVI practice and decision-making. Material and methods The Polish Interventional Cardiology TAVI Survey (PICTS) was approved by the Polish Association of Cardiovascular Interventions and presented to all 21 national TAVI centres. Between 2008 and 2015 the cumulative number of TAVI performed in Poland was 2189. The annual number of TAVI rose from 8 in 2008 to 670 in 2015 (0.21 to 17.4 implants per million inhabitants, respectively). Results The median TAVI experience per centre was 80 procedures (95% CI: 38.1–154.6). In 2015 the TAVI penetration rate reached 5.12% of the estimated eligible Polish population. Inoperable and high-risk patients are treated with TAVI in all centres, with 52% of Heart Teams also qualifying medium-risk patients. The rate of transfemoral implantations increased to 83.2% of all procedures in 2015, while transapical implantations decreased to 12%. The frequency of subclavian, direct aortic or transcarotid routes in 2015 was below 3% each. Conclusions The PICTS survey observed a positive but slow rate of adoption of TAVI in Poland. When compared to Western European countries, our findings highlight a significant treatment gap in high or prohibitive surgical risk patients with severe aortic stenosis. Remarkable variations in TAVI practices among Polish TAVI centres warrant publication of joint national guidelines and recommendations. PMID:28344612

    Osman Ümit Özen


    Full Text Available There are 27 municipal libraries including the Central Public Library in Munich. The other important libraries in the city are Bayern State National Library, Maximillian University Library, a technical highschool library and the "Deutsches Musuem" Library. All these libraries are financed locally. The author introduces these libraries briefly and compares German libraries with Turkish libraries. He concludes that although theoretically there are not distinctive differences, in practice, buildings and their layout are better in Germany where more variety of services are offered. In Turkey standardization has not been realized yet. Turkey needs to computerize and network to improve the services offered in an efficient way.

    . Simulation makes those reforms comparable over time and across countries. Results show that the profile of the German scheme is changing from "general family" towards "dual-earner" support. Furthermore, the recent reforms make the German scheme converge towards the Swedish leave scheme. The recent reforms....... Microsimulation helps to overcome these problems. It compares policy options - actual reforms or reform plans - simultaneously and provides a comparable measure: the disposable income of model families. This article uses a type-case approach to investigate recent reforms of the German parental leave benefit...... introduce a new concept of fairness and a focus on gender equality to German family policies....

  11. [Polish medical ethics in the period 1945-1980]. (United States)

    Wichrowski, Marek


    The purpose of this article is o present that main currents of Polish medical ethics in the years 1945-1980, which the author treats as the 'prehistory' of Poland's contemporary bioethics. The author begins by ascertaining the post-war disappearance of two Polish traditions--that of the Warsaw school of philosopher-physicians (known in the West as the Polish School of Philosophy of Medicine) and the Lwów-Warsaw School of Philosophy. The political system that come into being after 1945 was not conducive to the development of medical ethics, but several clear orientations may be discerned in the utterances of physicians, lawyers, moral technologlans and academic philosophers. The analysis begins with Catholic ethics in its archaic 1950s-vintage form. The author then presents the thinking of ethicians Independent of both the Church and Marxism (the milieu of the journal 'Etyka') as well as the deontological writings of physicians.

    Zita Matoušová Malbohanová


    Full Text Available Measurements of 17 body measures and 11 indices of body conformation on 209 breeding individuals of the Hucul horse were used to analyse the effect of country of origin (Poland and the Czech Republic, sex (stallions and mares, age (5 classes and sire line (Gurgul, Goral, Oušor, Hroby, Polan, Pietrosu, Prislop. All horses were measured by one person. Measures and indexes were analysed by the GLM procedure. The main effect was the country of origin. Highly significant differences were found between both Polish and Czech horses in two thirds of measurements and in more than half of indices. The Czech Hucul horses are significantly higher, longer, wider in pelvis and have longer head than Polish horses. On the contrary to the Czech horses are Polish horses more compact, massive and have deeper chest. Their cannon bone in relation to height of wither is wider.

    Agnieszka Kaczmarek-Kacprzak


    Full Text Available The paper “Human factors in nuclear power engineering in Polish conditions” focuses on analysis of dynamics of preparing Polish society to build fi rst nuclear power plant in XXI century in Poland. Authors compare experience from constructing nuclear power plant Sizewell B (Great Britain and Sizewell C, which is in preparation phase with polish nuclear power program. Paper includes aspects e.g. of creating nuclear safety culture and social opinion about investment. Human factors in nuclear power engineering are as well important as relevant economical and technical factors, but very often negligible. In Poland where history about Czarnobyl is still alive, and social opinion is created on emotions after accident in Fukushima, human factors are crucial and should be under comprehensive consideration.

  14. The social shaping of innovation in polish companies

    DEFF Research Database (Denmark)

    Lorentzen, Anne


    The paper deals with strategies of innovation in Polish manufacturing companies. The point of departure is a theoretical framework of enterprise level innovation, and of the factors forming strategies of innovation on enterprise level. The paper analyses evidence from 23 Polish companies...... and presents two cases more in detail. The analysis shows that the Polish companies have all been quite innovative, mostly in relation to product innovation. They choose innovation strategies, which are incremental more than radical, and they tend to differentiate their product range rather than to specialise....... They consider quality development a must in the fight for market shares and they adapt equipment and organisation to this goal. The factors forming and determining the strategies of the companies count the technological knowledge and expertise of the owner/founder, the structural changes of the market...

  15. ABCB1 3435C>T and 2677G>T/A polymorphisms in Polish and Bosnian patients with Crohn’s disease – A preliminary report

    Krzysztof Borecki


    Full Text Available The role of ABCB1 single nucleotide polymorphisms (SNPs in the development of Crohn’s disease (CD remains unclear. Due to inconsistent results of several European population-based studies and limited information on populations from Poland and Bosnia and Herzegovina (B&H, we conducted a preliminary association study of two main ABCB1 SNPs and CD. ABCB1 3435C>T and 2677G>T/A SNPs were analyzed in Polish and Bosnian patients with CD (n = 85 and n = 30, respectively and controls (n = 82 and n = 30, respectively using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP for 3435C>T and allele-specific PCR for 2677G>A/T SNP. A deviation from Hardy-Weinberg equilibrium was found for both SNPs in Polish patients with CD, and for 2677G>A/T in Polish control group. The allele and genotype frequencies of the two ABCB1 SNPs were not significantly different between the CD patients and controls in both populations (p > 0.05. Similarly, the genotype distribution of 3435C>T and 2677G>T/A SNPs was not significantly different between Polish and Bosnian patients with CD (p > 0.05. At least one mutated ABCB1 allele was carried by 97.7% of Polish and 90.0% of Bosnian patients with CD. No association was found between the ABCB1 SNPs and CD in the two populations. In conclusion, the two ABCB1 SNPs may not contribute to CD susceptibility in the populations of Poland and B&H. Further studies with larger samples in both populations are warranted.

  16. [The historical significance of the Polish medical faculty in Edinburgh]. (United States)

    Nowak, K


    The Polish Medical Faculty at the University of Edinburgh was a unique phenomenon in the history of universities. Established during the Second World War in 1941 as an entirely autonomous Polish academic institution, the Faculty trained 228 doctors and awarded 19 PhD degrees during its nine years of formal existence (1941-1949). In reviewing its almost 60-year old history, seen in the context of the involvement of the elite of both the political and academic establishments, the splendour of various celebrations and its graduates devotion in keeping the "Edinburgh experiment" alive, the author makes a case for the long-term historical and psychological significance of events well outlasting the period of formal activity of the Faculty. The history of the Faculty is well documented, but the long term outcome in terms of its lasting historical importance is gradually emerging with the passage of time. It has become an indisputable testimony to the generosity and hospitality of the Scottish (political and) academic establishment and a lasting proof of the special liaison between the Scots and the Poles. The Faculty's importance and psychological significance to the rich historical heritage of Polish medicine and the notion of patriotism and loyalty to Polishness have become apparent in the ensuing decades of its carefully maintained tradition. The existence of the Polish Medical Faculty has become an extraordinary asset in the history of Scottish universities, but for the Polish tradition both in Poland and throughout its rich diaspora it constitutes an increasingly valuable historical event which deserves to be cultivated and passed on to younger generations so that it may continue bringing further dividends, so important to national identity, achievement, dignity and pride.

  17. Verbalization the Concept of Dignity in Polish Dictionaries

    Directory of Open Access Journals (Sweden)

    Chaban Vasylyna


    Full Text Available Background: The object of the study is the concept of DIGNITY. The justification of the research is predetermined by the lack of such investigation in Polish linguistics. The background for the article is also determined by the lack of similar studies in the sphere of Cognitive Linguistics. Purpose: The article aims at analysing the cultural concept of DIGNITY in the minds of the bearers of the Polish language and culture based on the data incorporated from the lexicographical sources and collection of folk sayings and proverbs. Results: The article dwells upon the most important features of this concept in the Polish language and culture. The study investigates the language conceptualization of this concept in the system of the Polish language and folk maxims and sayings. The definition of the lexeme of dignity reveals the compliance with higher moral principles and the understanding of value; good name, good character claiming attention and respect; the last name. DIGNITY is the principal regulating mechanism of behaviour and development of positive human values which become apparent in the process of human interaction. A man of worth respects himself and is as well proud to be an honourable man. DIGNITY concerns both a separate human and the society in general; it could be regarded as both individual and collective notion. Discussion: The suggested analysis revealed cultural and linguistic peculiarities of the concept of DIGNITY in the Polish language and culture. The conducted research is not exhaustive since it provides potential perspectives for further research of the Polish concept of DIGNITY, in particular, in terms of comparative studies with correlative concepts in Ukrainian and English languages and cultures with the help of the cognitive definition method.

  18. Laser polishing of 3D printed mesoscale components (United States)

    Bhaduri, Debajyoti; Penchev, Pavel; Batal, Afif; Dimov, Stefan; Soo, Sein Leung; Sten, Stella; Harrysson, Urban; Zhang, Zhenxue; Dong, Hanshan


    Laser polishing of various engineered materials such as glass, silica, steel, nickel and titanium alloys, has attracted considerable interest in the last 20 years due to its superior flexibility, operating speed and capability for localised surface treatment compared to conventional mechanical based methods. The paper initially reports results from process optimisation experiments aimed at investigating the influence of laser fluence and pulse overlap parameters on resulting workpiece surface roughness following laser polishing of planar 3D printed stainless steel (SS316L) specimens. A maximum reduction in roughness of over 94% (from ∼3.8 to ∼0.2 μm Sa) was achieved at the optimised settings (fluence of 9 J/cm2 and overlap factors of 95% and 88-91% along beam scanning and step-over directions respectively). Subsequent analysis using both X-ray photoelectron spectroscopy (XPS) and glow discharge optical emission spectroscopy (GDOES) confirmed the presence of surface oxide layers (predominantly consisting of Fe and Cr phases) up to a depth of ∼0.5 μm when laser polishing was performed under normal atmospheric conditions. Conversely, formation of oxide layers was negligible when operating in an inert argon gas environment. The microhardness of the polished specimens was primarily influenced by the input thermal energy, with greater sub-surface hardness (up to ∼60%) recorded in the samples processed with higher energy density. Additionally, all of the polished surfaces were free of the scratch marks, pits, holes, lumps and irregularities that were prevalent on the as-received stainless steel samples. The optimised laser polishing technology was consequently implemented for serial finishing of structured 3D printed mesoscale SS316L components. This led to substantial reductions in areal Sa and St parameters by 75% (0.489-0.126 μm) and 90% (17.71-1.21 μm) respectively, without compromising the geometrical accuracy of the native 3D printed samples.

  19. Loneliness among Polish migrants in the Netherlands: The impact of presence and location of partners and offspring

    Directory of Open Access Journals (Sweden)

    Thijs van den Broek


    Full Text Available Background: Research using nonmigrant samples indicates that having a partner and children is protective against loneliness. Such beneficial effects may be weaker for migrants with partners and/or children living in different countries. Objective: We assess how feelings of loneliness among Polish migrants in the Netherlands compare to levels among the general Dutch population and how migrants' feelings of loneliness vary by presence and location of partners and offspring. Methods: We used weighted data from the Families of Poles in the Netherlands survey (n=1,129. Wald tests were used to compare levels of loneliness among Polish migrants with scores reported in a different study for the general Dutch population. Linear regression was used to estimate how presence and location of partners and children were associated with loneliness. Results: Polish migrants in the Netherlands were lonelier than the general Dutch population. Among men, those who had been in the Netherlands for longer were lonelier than those who had more recently arrived. Unpartnered men and men with a partner living abroad were lonelier than men with a partner living in the Netherlands. For women, no effects of presence and location of a partner were found. Presence and location of children made little difference. Conclusions: Although loneliness is often considered a problem for older individuals, feelings of loneliness are also strong among working-age Polish migrants. Consistent with studies on nonmigrant samples, we found that men with a partner were less lonely than unpartnered men, but only when the partner also resided in the Netherlands.

  20. The German Chernobyl project: Lessons learned

    International Nuclear Information System (INIS)

    Hill, P.; Hille, R.


    This report presents results and lessons learned by one of the so far largest assessments of a post-accidental situation. Funded by the Federal Republic of Germany the German Chernobyl Project investigated in the years 1991-1993 the radiological situation in contaminated regions of the Russian Federation, Belarus and Ukraine. Measurements included a mass screening of the population in order to determine the Cesium body burdens of 250,000+ individuals in more than 240 settlements as well as the evaluation of external doses in selected settlements with soil contaminations varying from less than 74 kBq/m 2 to about 3700 kBq/m 2 including some, where decontamination measures had previously been taken. Also in many settlements environmental monitoring was undertaken. For most individuals doses did not exceed the international annual limits set for the general population. Open and comprehensive communication of results was favourably accepted by the public. In a few settlements the radiological situation has been followed up till to date. (author)

  1. The assessment of orthorexia nervosa among 1899 Polish adolescents using the ORTO-15 questionnaire. (United States)

    Hyrnik, Joanna; Janas-Kozik, Małgorzata; Stochel, Martyna; Jelonek, Ireneusz; Siwiec, Andrzej; Rybakowski, Janusz K


    Orthorexia nervosa (ON) is considered an eating disorder (ED), with an excessive fixation on the consumption of healthy food and an obsession with its biological purity. Since the adolescent period poses a risk for EDs, the aim of this study was to assess the prevalence of ON in a population of Polish urban adolescents and some possible contributory factors. 1899 high school students, 992 girls and 907 boys aged 15-21 years were studied. Demographic and clinical data were collected using a validated questionnaire including information on preferred living choices, in the context of pro- and antihealth activities. The Polish version of the ORTO-15 questionnaire was used. The mean value of the ORTO-15 was 39.2 ± 3.6 points, with no sex difference. The main factors connected with orthorexia, according to the 'Orthorexia 33.35 and 40' definitions were excess weight, sporting activities, out-of-school activities, smoking status, working parents and a high family income. This study, of a large number of adolescents, showed a prevalence of ON similar to that recorded in adult populations. Since factors predisposing to ON in adolescence differ from those for other eating disorders, it is not clear whether ON should be treated as a new form of ED.

    Baran, Sylwia; Teul-Swiniarska, Iwona; Dzieciolowska-Baran, Edyta; Lorkowski, Jacek; Gawlikowska-Sroka, Aleksandra


    The aim of the paper was to examine the association between the psychological status and the occurrence of respiratory tract infections which constitute the most common group of disorders in the student population. The study comprised 500 Polish students aged 19-21. Two psychological scales were utilized: the Goldberg GHQ-12 scale to examine the general psychological status and the CES-D scale to evaluate the symptoms of depression. In addition a pro-health questionnaire in the examined group of students was performed. We found an increased stress level in 51% of students and the symptoms of depression in 22%. An association between distress and the occurrence of respiratory tract infections was found, based on statistical analyses. The highest stress level and related high distress index were observed in the students suffering from lower respiratory tract infections (7.1 scale value). This group self-evaluated their health status as poor, based on the pro-health questionnaire. In the same group of students, lack of sleep (5.4), lack of regular eating habits (4.2) and lack of physical activity (3.9) were also observed. The study shows that the Polish student population is exposed to increased stress level, which, in turn, increases the occurrence of respiratory tract infections.

  3. Cultural events – does attendance improve health? Evidence from a Polish longitudinal study

    Directory of Open Access Journals (Sweden)

    Dorota Węziak-Białowolska


    Full Text Available Abstract Background Although there is strong advocacy for uptake of both the arts and creative activities as determinants of individual health conditions, studies evaluating causal influence of attendance at cultural events on population health using individual population data on health are scarce. If available, results are often only of an associative nature. In this light, this study investigated causative impact of attendance at cultural events on self-reported and physical health in the Polish population. Methods Four recent waves (2009, 2011, 2013 and 2015 of the biennial longitudinal Polish household panel study, Social Diagnosis, were analysed. The data, representative for the Polish population aged over 16, with respect to age, gender, classes of place of residence and NUTS 2 regions, were collected from self-report questionnaires. Causative influence of cultural attendance on population health was established using longitudinal population representative data. To account for unobserved heterogeneity of individuals and to mitigate issues caused by omitted variables, a panel data model with a fixed effects estimator was applied. The endogeneity problem (those who enjoy good health are more likely to participate in cultural activities more frequently was circumvented by application of instrumental variables. Results Results confirmed positive association between cultural attendance and self-reported health. However, in contrast to the often suggested positive causative relationship, such a link was not confirmed by the study. Additionally, no evidence was found to corroborate a positive impact from cultural attendance on physical health. Both findings were substantiated by augmentation in the longitudinal perspective and causal link. Conclusions We showed the relation between attendance at cultural events and self-reported health could only be confirmed as associational. Therefore, this study provided little justification to encourage use

[College of William and Mary, Williamsburg, VA (United States); Thomas Jefferson National Accelerator Facility (TJNAF), Newport News, VA (United States)


    Improved energy efficiency and reduced cost are greatly desired for advanced particle accelerators. Progress toward both can be made by atomically-smoothing the interior surface of the niobium superconducting radiofrequency accelerator cavities at the machine's heart. Laser polishing offers a green alternative to the present aggressive chemical processes. We found parameters suitable for polishing niobium in all surface states expected for cavity production. As a result, careful measurement of the resulting surface chemistry revealed a modest thinning of the surface oxide layer, but no contamination.

  7. Mechanistic, kinetic, and processing aspects of tungsten chemical mechanical polishing (United States)

    Stein, David

    This dissertation presents an investigation into tungsten chemical mechanical polishing (CMP). CMP is the industrially predominant unit operation that removes excess tungsten after non-selective chemical vapor deposition (CVD) during sub-micron integrated circuit (IC) manufacture. This work explores the CMP process from process engineering and fundamental mechanistic perspectives. The process engineering study optimized an existing CMP process to address issues of polish pad and wafer carrier life. Polish rates, post-CMP metrology of patterned wafers, electrical test data, and synergy with a thermal endpoint technique were used to determine the optimal process. The oxidation rate of tungsten during CMP is significantly lower than the removal rate under identical conditions. Tungsten polished without inhibition during cathodic potentiostatic control. Hertzian indenter model calculations preclude colloids of the size used in tungsten CMP slurries from indenting the tungsten surface. AFM surface topography maps and TEM images of post-CMP tungsten do not show evidence of plow marks or intergranular fracture. Polish rate is dependent on potassium iodate concentration; process temperature is not. The colloid species significantly affects the polish rate and process temperature. Process temperature is not a predictor of polish rate. A process energy balance indicates that the process temperature is predominantly due to shaft work, and that any heat of reaction evolved during the CMP process is negligible. Friction and adhesion between alumina and tungsten were studied using modified AFM techniques. Friction was constant with potassium iodate concentration, but varied with applied pressure. This corroborates the results from the energy balance. Adhesion between the alumina and the tungsten was proportional to the potassium iodate concentration. A heuristic mechanism, which captures the relationship between polish rate, pressure, velocity, and slurry chemistry, is presented

  9. Confocal Raman spectrocopy for the analysis of nail polish evidence. (United States)

    López-López, Maria; Vaz, Joana; García-Ruiz, Carmen


    Nail polishes are cosmetic paints that may be susceptible of forensic analysis offering useful information to assist in a crime reconstruction. Although the nail polish appearance could allow a quick visual identification of the sample, this analysis is subjected to the perception and subjective interpretation of the forensic examiner. The chemical analysis of the nail polishes offers great deal of information not subjected to analyst interpretation. Confocal Raman spectroscopy is a well-suited technique for the analysis of paints due to its non-invasive and non-destructive nature and its ability to supply information about the organic and inorganic components of the sample. In this work, 77 regular and gel nail polishes were analyzed with confocal Raman spectroscopy using two laser wavelengths (532 and 780 nm). The sample behavior under the two laser wavelengths and the differences in the spectra taken at different points of the sample were studied for each nail polish. Additionally, the spectra obtained for all the nail polishes were visually compared. The results concluded that the longer laser wavelength prevents sample burning and fluorescence effects; the similarity among the spectra collected within the sample is not directly related with the presence of glitter particles; and 64% of the samples analyzed showed a characteristic spectrum. Additionally, the use of confocal Raman spectroscopy for the forensic analysis of nail polishes evidence in the form of flakes or smudges on different surfaces were studied. The results showed that both types of evidence can be analyzed by the technique. Also, two non-invasive sampling methods for the collection of the evidence from the nails of the suspect or the victim were proposed: (i) to use acetone-soaked cotton swabs to remove the nail varnishes and (ii) to scrape the nail polish from the nail with a blade. Both approaches, each exhibiting advantages and drawbacks in terms of transport and handling were appropriate

  13. [German language physician rating sites]. (United States)

    Strech, D; Reimann, S


    In physician rating sites (PRS), patients are able to share their experiences and indicate their satisfaction in qualitative and quantitative form. This information should support other patients in the search for a suitable physician and can serve as a form of anonymous feedback for physicians. Medical association representatives are often concerned that such reviews primarily aim at defamation. Furthermore, there are various aspects of medical work that cannot be adequately evaluated solely through the patients. In the United States of America, the majority of such previous reviews were shown to be positive. It has yet to be examined in the German and English speaking regions where distinct criteria presently allow patients to express their satisfaction through PRS. Based on the systematic review of patient satisfaction questionnaires, a set of criteria was created that represents the dimensions of patient satisfaction. German and English language physician rating sites were systematically researched using the Internet search machines "Google" and "Yahoo". The identified PRS were then evaluated with the help of the aforementioned set of criteria. In order to survey the tendency of the amount and content of reviews, a stratified sample of members of the Panel Doctor's Association in Hamburg and Thuringia was generated. A total of 298 randomly selected physicians were searched for in 6 German-language PRS regarding potential reviews. Some of the key features of the relation-ship between physicians and patients, such as medical competence, information, and consultation, were surveyed by more than three-fourths of the German-speaking PRS; however, other features such as communication were only sampled by one. As opposed to formal points of view, office facilities and organisation were assessed by all PRS. General reviews on treatment success and satisfaction were displayed in more than half of the reviews. Between 75% and 98% of physicians from the random sampling

  14. Health-related quality of life in overweight German children and adolescents: do treatment-seeking youth have lower quality of life levels? Comparison of a clinical sample with the general population using a multilevel model approach. (United States)

    Finne, Emily; Reinehr, Thomas; Schaefer, Anke; Winkel, Katrin; Kolip, Petra


    Health-related quality of life (HRQoL) is reduced in obese children and adolescents, especially in clinical samples. However, little is known regarding the HRQoL of moderately overweight youth. Moreover, several studies have indicated perceived overweight as a critical factor associated with lower HRQoL. Our main objective was to compare HRQoL between treatment-seeking overweight youth and the general adolescent population, whilst separating the effects of treatment-seeking status and perceived weight from those of objective weight status. We compared the HRQoL of a clinical sample of overweight youth (N=137 patients, mean age±s.e.=11.24±0.15 years) with that of a representative population sample (N=6354, mean age=12.75±0.03 years). The population sample was subdivided into groups based on measured and perceived weight status. We used hierarchical linear models to compare HRQoL subscale scores (self- and parent-reported) between patients and population groups, adjusted for sociodemographic characteristics and taking into account clustering of the population sample. The parent-reported HRQoL of the treatment sample was significantly lower than that of other overweight youth perceived as 'too fat' on two subscales: 'self-esteem' and 'friends' (effect sizes: d=0.31 and 0.34, respectively). On other subscales, patients scored lower than adolescents perceived as having a 'proper weight' by their parents. The patterns for self-reported HRQoL in adolescents were different: patients reported higher self-esteem than other overweight youth feeling 'too fat' (d=-0.39). Female patients also reported higher physical well-being (d=-0.48), whereas males scored lowest among all compared groups (d=0.42-0.95). Patients did not differ from other overweight youth who felt 'too fat' with respect to other HRQoL dimensions. In general, lower HRQoL was primarily associated with a perceived, rather than actual, overweight status. The treatment-seeking status of overweight youth was

  15. Simulation and analysis of an alternative kinematics for improving the polishing uniformity over the surface of polished tiles

    Directory of Open Access Journals (Sweden)

    Weingaertner, W. L.


    Full Text Available The present work investigates the possibility of adopting a new kinematics at the industrial polishing lines of porcelain stoneware tile. An alternative motion of the transverse oscillation of the polishing heads is proposed, in which no radical changes in the industries facilities are required. The basic idea is to replace the purely sinus motion of the polishing heads by a rather trapezoid wavelike motion. In theory this could be achieved simply by adopting regular delays at the transverse oscillation motion. Consequences of this alternative kinematics were quantitatively analyzed considering the spatial homogeneity of polishing expected for tiles. Such homogeneity was represented by the coefficient of variation of the distribution of polishing time over the surface, which was in turn determined by means of computational simulations, taking into account the effect of multiple polishing heads.

    El presente trabajo investiga la posibilidad de adoptar una nueva cinemática en las líneas de pulido industrial de baldosas de gres porcelánico. Se propone una propuesta alternativa de la oscilación transversal de los cabezales pulidores, en el que no hay cambios radicales en las instalaciones de las industrias son necesarias. La idea básica consiste en sustituir el movimiento totalmente del seno de los cabezales pulidores por un movimiento ondulatorio trapezoide. En teoría, esto podría lograrse sólo mediante la adopción de los habituales retrasos en el movimiento de oscilación transversal. las consecuencias de esta cinemática fueron analizados cuantitativamente, teniendo en cuenta la homogeneidad espacial de pulido. Tal homogeneidad fora representada por el coeficiente de variación de la distribución de lo tiempo de pulido en la superficie, determinada por medio de simulaciones computacionales, teniendo también en cuenta el efecto de pulido de las cabezas múltiples.

  17. Nutrition and nourishment status of Polish students in comparison with students from other countries. (United States)

    Szczuko, Małgorzata; Gutowska, Izabela; Seidler, Teresa


    Although Poland belongs to the economically developed countries, social transformations affect people's incomes and, consequently, their diets, what in many cases caused development of diet-related diseases. Results of epidemiological studies among students show symptoms of certain civilization diseases. The aim of this study was to compare the intake of nutrients by Polish students in our study with the nutrients intake by students from other university centres abroad and the determination of the direct impact on health parameters of educated people. The study involved 329 Polish students. The dietary information was collected by interview on food intake during the last 24 hours. The index of BMI and WHR were calculated using anthropometric method. 27 nutrients, dietary fibre and daily total cholesterol intake with the computer program "Dietetyk 2" (National Food and Nutrition Institute, Warsaw, Poland). Both women and men consume inadequate amounts of milk and dairy products, fruits, vegetables, vitamin C and iron. The average daily intake of vitamin C and iron was below the standard of nutrition. Diets in men was characterized by excessive content of meat and in women sucrose. 35% of the students surveyed were overweight or obese. There was a lot of irregularities in the diet of both women and men, but men's diet was more balanced in terms of nutrient content than the diet of women. The delivery of thiamine, riboflavin, calcium, and vitamin C is less in Polish students than in other populations compared. Nutritional mistakes and dietary habits during studies can influence the development of disease in young educated people.

    Full Text Available The GNB3 gene encodes the beta 3 subunit of heterotrimeric G-proteins that are key components of intracellular signal transduction between G protein-coupled receptors (GPCR and intracellular effectors and might be considered as a potential candidate gene for physical performance. Objectives: The aim of this study was to compare frequency distribution of the common C to T polymorphism at position 825 (C825T of the GNB3 gene between athletes and nonathletic controls of the Polish population as well as to compare the genotype distribution and allele frequency of C825T variants within a group of athletes, i.e. between athletes of sports of different metabolic demands and competitive levels. Methods: The study was performed in a group of 223 Polish athletes of the highest nationally competitive standard (123 endurance-oriented athletes and 100 strength/power athletes. Control samples were prepared from 354 unrelated, sedentary volunteers. Results: The χ2 test revealed no statistical differences between the endurance-oriented athletes and the control group or between sprint/strength athletes and the control group across the GNB3 825C/T genotypes. There were no male-female genotype or allele frequency differences in controls or in either strength/power or endurance-oriented athletes. No statistically significant differences in either allele frequencies or genotype distribution were noted between the top-elite, elite or sub-elite of endurance-oriented and strength/power athletes and the control group. Conclusions: No association between elite status of Polish athletes and the GNB3 C825T polymorphic site has been found.

  19. Provenance validation of polished rice samples using nuclear and isotopic analytical techniques

    International Nuclear Information System (INIS)

    Pabroa, P.C.B.; Sucgang, R.J.; Mendoza, N.D.S.; Ebihara, M.; Peña, M.


    Rice (Oryza sativa) has been considered the best staple food among all cereals and is the staple food for over 3 billion people, constituting over half of the world’s population. Elemental and isotopic analysis revealed variance between Philippine and Japanese rice. Rice samples collected in Japan and in the Philippines (market survey samples from Metro Manila, and farm harvests from Aklan province and Central Luzon) were washed, dried and ground to fine powder. Elemental analyses of the samples were carried out using instrumental neutron activation analysis (INAA) while isotopic signatures of the samples were determined using the isotope ratio mass spectrometry (IRMS). Results show that compared with the unpolished rice standard NIES CRM10b, the polished Japanese and Philippine rice sampled show reduced concentrations of elements by as much as 1/10. 1/4 , 1/5 and 1/3 for Mg, Mn, K and Na, respectively. Levels of Ca and Zn are not greatly affected. Arsenic, probably introduced from fertilizers used in rice fields is found in all the Japanese rice tested at an average concentration of 0.103 μg/g and three out of four of the Philippine rice at an average concentration of 0.70μg/g. Higher levels of Br seen in two of the Philippine rice at 14 and 34μg/g indicated probable contamination source from the pesticide methyl bromide during quarantine. Good correlation of isotopic signatures with geographical location of polished, but not for unpolished, rice samples from Central Luzon and Aklan indicated that provenance studies are best done on polished rice samples. Isotopic with of ω’”13C show signature that of a C3 plant with possible narrow distinguishable signature with Japanese rice falling within -27.5 to -28.5 while Philippine rice within -29 to -30. Rice provenance can be ascertained using elemental analysis and isotopic abundance determination as shown by the study.(author)

  20. Language-related differential item functioning between English and German PROMIS Depression items is negligible. (United States)

    Fischer, H Felix; Wahl, Inka; Nolte, Sandra; Liegl, Gregor; Brähler, Elmar; Löwe, Bernd; Rose, Matthias


    To investigate differential item functioning (DIF) of PROMIS Depression items between US and German samples we compared data from the US PROMIS calibration sample (n = 780), a German general population survey (n = 2,500) and a German clinical sample (n = 621). DIF was assessed in an ordinal logistic regression framework, with 0.02 as criterion for R 2 -change and 0.096 for Raju's non-compensatory DIF. Item parameters were initially fixed to the PROMIS Depression metric; we used plausible values to account for uncertainty in depression estimates. Only four items showed DIF. Accounting for DIF led to negligible effects for the full item bank as well as a post hoc simulated computer-adaptive test (German general population sample was considerably lower compared to the US reference value of 50. Overall, we found little evidence for language DIF between US and German samples, which could be addressed by either replacing the DIF items by items not showing DIF or by scoring the short form in German samples with the corrected item parameters reported.

  1. [Carotenoid intake in the German National Food Consumption Survey]. (United States)

    Pelz, R; Schmidt-Faber, B; Heseker, H


    In nutritional epidemiological studies high consumption of fruits and vegetables was shown to be an important preventive measure to reduce the risk of cancer, coronary heart disease, and cataracts. These effects cannot be explained completely and in a sufficient way by the intake of beta-carotene and vitamin C. Other carotenoids differing in their antioxidative and biological properties are also provided with fruits and vegetables in significant amounts. Because data for other carotenoids than beta-carotene are not considered in computerized German food database and food composition tables, representative carotenoid intake calculations for the German population are missing. Therefore a carotenoid database, containing alpha- and beta-carotene, lycopene, lutein/zeaxanthin, and cryptoxanthin values for different fruits, vegetables, and other carotenoid-containing foods, was developed. With this database the carotenoid intake of the German population--stratified by sex and age--was evaluated on the basis of the German National Food Consumption Survey (NVS). The mean total carotenoid intake amounts to 5.33 mg/day. The average intake lutein was 1.91 mg/day, beta-carotene intake amounts to 1.81 mg/day, lycopene intake was 1.28 mg/day, alpha-carotene intake was 0.29 mg/day, and cryptoxanthin intake was 0.05 mg/day. Tomatoes and tomato products provide most of the lycopene. Green salads and vegetables are the most important contributors of lutein in Germany. Zeaxanthin is mainly consumed with maize but also with spinach and other vegetables like cabbage; alpha- and beta-carotene are mainly consumed with carrots. Peppers, oranges, and orange-juice are the most important cryptoxanthin sources.

  17. Influence of the brittle behavior of work materials on polishing characteristics (United States)

    Sakamoto, Satoshi; Gemma, Masaya; Hayashi, Keitoku; Kondo, Yasuo; Yamaguchi, Kenji; Yakou, Takao; Arakawa, Susumu


    Diamond electrodeposited wire tools are frequently used to cut thin wafers from hard and brittle materials. However, microcracks sometimes appear during the slicing process. The appearance of microcracks adversely affects slicing efficiency and slicing accuracy. In this study, we examine the influence of brittle behavior on the polishing characteristics such as polishing depth and tool wear. This is the first step toward investigating the influence of the brittle behavior of work materials on slicing characteristics. Ceramics such as alumina, silicon carbide, and zirconia are used as work materials. Even with the same degree of hardness, we found that the polishing depth values were greater for materials exhibiting brittle behavior. In the polishing of high-hardness materials, abrasive grains were badly damaged during the initial stages of polishing. Damage to the abrasive paper was less in wet polishing as compared with dry polishing. Moreover, wet polishing had a greater polishing depth than dry polishing. The polishing characteristics of the brittle materials were similar to the grooving characteristics produced using wire tools; however, both these characteristics depend on the brittle behavior of the work materials. Therefore, by performing simple polishing tests, estimating the state of grooving or slicing using wire tools is possible.

  2. [Surveillance of hospital acquired pneumonia in Polish hospitals]. (United States)

    Rózańska, Anna; Wójkowska-Mach, Jadwiga; Bulanda, Małgorzata; Heczko, Piotr B


    The aim of this work is to analyze epidemiology of hospital acquired infections in Polish hospitals, according to type and size of hospital. Data gathered between year 2002 and 2004 in the Active Nosocomial Infections Surveillance System, developed and conducted by Polish Society of Hospital Infections, were used in the analysis. Epidemiology of PNEU was described with the usage of cumulative incidence and incidence density rates. The average cumulative incidence rate was 0.29%; incidence density rate: 0.41 per thousand, and incidence density among ventilated patients: 1.57 per thousand. Differences in morbidity detected in hospitals were statistically important only in hospitals of different size. Morbidity of PNEU in intensive care units was much higher than in other wards, and differences were statistically important. PNEU and VAP epidemiology in Polish intensive care units indicates serious problems in hospital infections control: high values of morbidity in non-teaching ICUs reflect the huge risk of developing infections in Polish hospitals. Low rates in ICUs of teaching hospitals reflect lack of surveillance and detection of infections in such hospitals.

  6. [Polish doctors graves at the cemeteries in Edinburgh]. (United States)

    Gebertt, S


    The first part of the text reviews the cultural links between Poland and Scotland. These links were originated in the 14th century and were created by scottish students travelling to Poland to seek learning in the then polish centre of excellence Jagiellonian University in Cracow. There were also some learned Scots who ventured to Poland, seeking work. Some of them achieved positions of distinction. The first Polish medical men attended the University of Edinburgh in the 18th century. In the 19th century, following the suppression of the polish uprising against Russia, there were a small group of Poles seeking asylum in Scotland. A few of them enlisted at the University of Edinburgh at the medical faculty. The above history is described in detail in Annotations. In the second part of the paper all the polish medical and veterinary doctors whose graves are located in various cemeteries in Edinburgh are listed in chronological order of their deaths. As full as possible personal data, the kind of medical work, and location of their graves are given. Greater details, whenever obtainable, are dealt with in Annotations. The total of thirty deceased between 1942 and 1993 are described.

  11. Clear and compelling evidence: the Polish tribunal on abortion rights. (United States)

    Girard, Françoise; Nowicka, Wanda


    On 25 July 2001 the Polish Federation for Women and Family Planning organised a Tribunal on Abortion Rights in Warsaw, to publicize the negative consequences of the criminalization of abortion in Poland. A panel of Polish and foreign experts heard the testimonials of seven Polish women's experiences under the 1993 "Anti-Abortion Act". Only two of the seven women were able to tell their stories in person. One died in 2001, at the age of 21, of an unsafe abortion. One is legally blind after having carried her last pregnancy to term. One is in prison for infanticide, which in all likelihood was committed by her boyfriend. National and foreign journalists were in attendance, as well as observers from all walks of life--writers, students, mothers, activists, feminists, husbands. The evidence was clear and compelling. Restrictive abortion laws make abortion unsafe by pushing it underground, endanger women's health, create a climate where even those services that are allowed by law-become unavailable, and contravene standards set by international human rights law. The restrictive abortion law in Poland has not increased the number of births; it has only caused women and their families suffering. The Tribunal brought the issue of abortion into the media prior to an election campaign and galvanised Polish and other Eastern European women's groups to become more active in defence of abortion rights.

  14. Heavy Metal Contamination of Popular Nail Polishes in Iran

    Directory of Open Access Journals (Sweden)

    Golnaz Karimi


    Full Text Available Background: Toxic and hazardous heavy metals like arsenic, lead, mercury, zinc, chromium and iron are found in a variety of personal care products, e.g. lipstick, whitening toothpaste, eyeliner and nail color. The nails absorb the pigments of nail polishes and vaporized or soluble metals can easily pass it. The goal of this survey was to assess whether the different colors of nail polishes comply with maximum concentrations of heavy metals in the EPA’s guidelines. Methods: 150 samples of different popular brands of nail polishes in 13 colors (yellow, beige, silver, pink, white, violet, brown, golden, green, black, colorless, red and blue were randomly purchased from beauty shops in Tehran City, Iran, in 2014. Microwave digestion EPA method 3051 was used by a microwave oven to determine the amount of 5 heavy metals; Nickel, Chromium, Lead, Arsenic and Cadmium. One-way ANOVA, Two-way ANOVA, hierarchical cluster, and principal component analyses were applied by Statistica 7.0 software. Results: The concentrations of chrome, lead, nickel and arsenic showed significant differences between the colors (p<0.05. In all studied samples, the level of cadmium was beyond the safe maximum permissible limit (MPS, but no significance difference in the cadmium content was identified. Conclusion: Due to the high concentrations of toxic metals in many brands of nail polishes, meticulous quality control is recommended for these beauty products.

    Glowacki, Maciej; Misterska, Ewa; Laurentowska, Maria; Mankowski, Przemyslaw


    Polish adaptation of the original version of Scoliosis Research Society (SRS) instrument. The transcultural adaptation of SRS-22 and evaluation of its internal consistency. High psychometric value of the SRS-22 Questionnaire has made it an effective evaluation instrument in clinically assessing the functional status of patients with adolescent idiopathic scoliosis. First, 2 translators translated the original version into Polish. Afterwards, the translators identified differences between the translations and produced a consensus version. In the third stage, 2 native English speakers produced back translations. Finally, a team of 2 orthopedic surgeons, translators, a statistician and a psychologist reviewed all the translations to produce a prefinal version. The questionnaire was administered to 60 girls at the age of 16.6, SD 2.0 with adolescent idiopathic scoliosis treated with the Cotrel-Dubousset method in Pediatric Orthopaedics and Traumatology Clinic in Poznań. The internal consistency in the Polish version equaled 0.89 for the overall result and 0.81 for function, 0.81 for pain, 0.80 for mental health, 0.77 for self-image, and 0.69 for treatment satisfaction domains, respectively. The Polish version of SRS-22 is characterized by high internal consistency for all domains and for the overall score, which makes it an evaluation tool after surgical treatment compatible with the original SRS-22.

  17. Estimation of drug abuse in 9 Polish cities by wastewater analysis. (United States)

    Klupczynska, Agnieszka; Dereziński, Paweł; Krysztofiak, Janusz; Kokot, Zenon J


    The aim of this work was to measure illicit drug residues in raw sewage samples collected from nine Polish cities in order to determine trends in illicit drug use in these urban populations. This is the first study involving an analysis of samples from several sewage treatment plants in Poland and covering such a large population. Concentration of illicit drugs was determined using a high performance liquid chromatography-tandem mass spectrometry method. The samples were subjected to a multistep preparation procedure with a solid phase extraction as a main pre-treatment step. Among the selected drugs investigated in the study, amphetamine was found in the greatest amounts in all sewage samples and consequently was the most prevalent drug of abuse. Higher loads of illicit drug residues were found during weekends compared to the weekdays, especially for 3,4-methylenedioxymethamphetamine (ecstasy) and benzoylecgonine, main metabolite of cocaine.

    of a general trend in Europe. We therefore carried out a prospective study of semen quality of young men raised in the former East Germany (Leipzig) and West Germany (Hamburg). To enable inter-regional comparisons, we utilized a common European research protocol previously used in studies in the Nordic......-Baltic region. Three hundred and thirty-four young men representative of the general population from Hamburg, and 457 from Leipzig delivered semen samples, underwent physical examinations and provided information on life-style and reproductive health parameters. The study period in Hamburg was February 2003......--July 2004, and in Leipzig July 2003--April 2005. No significant differences were observed in sperm concentration (median 46, 42, and 44 million/mL for men from Hamburg, Leipzig and the combined Hamburg-Leipzig group respectively) or total sperm count (154,141 and 149 million), whereas the differences...

  19. Urban Green Infrastructure: German Experience

    Directory of Open Access Journals (Sweden)

    Diana Olegovna Dushkova


    Full Text Available The paper presents a concept of urban green infrastructure and analyzes the features of its implementation in the urban development programmes of German cities. We analyzed the most shared articles devoted to the urban green infrastructure to see different approaches to definition of this term. It is based on materials of field research in the cities of Berlin and Leipzig in 2014-2015, international and national scientific publications. During the process of preparing the paper, consultations have been held with experts from scientific institutions and Administrations of Berlin and Leipzig as well as local experts from environmental organizations of both cities. Using the German cities of Berlin and Leipzig as examples, this paper identifies how the concept can be implemented in the program of urban development. It presents the main elements of green city model, which include mitigation of negative anthropogenic impact on the environment under the framework of urban sustainable development. Essential part of it is a complex ecological policy as a major necessary tool for the implementation of the green urban infrastructure concept. This ecological policy should embody not only some ecological measurements, but also a greening of all urban infrastructure elements as well as implementation of sustainable living with a greater awareness of the resources, which are used in everyday life, and development of environmental thinking among urban citizens. Urban green infrastructure is a unity of four main components: green building, green transportation, eco-friendly waste management, green transport routes and ecological corridors. Experience in the development of urban green infrastructure in Germany can be useful to improve the environmental situation in Russian cities.

  1. Polish Geophysical Solid Earth Infrastructure Contributing to EPOS (United States)

    Debski, W.; Mutke, G.; Suchcicki, J.; Jozwiak, W.; Wiejacz, P.; Trojanowski, J.


    In this poster we present the current state of the main polish solid-earth-orientated infrastructures and shortly described history of their development, current state, and some plans for their future development. The presen- tation concentrates only on the classical infrastructure leaving aside for the while the the geodetic-orientated infrastructure, like GPS network and the GPS processing data centers, gravimetric infrastructure and others of this type. Polish broadband seismic infrastructure consists of 7 permanent broadband stations incorporated into the VEBSN initiative running at the polish territory and one operated in collaboration with NORSAR is settled at the Hornsund (Svalbard) polish polar station. All stations are equipped with STS-2 seismometers and polish MK-6 seismic stations providing 120 dB dynamics 100Hz sampling and data transmission in a real time to processing center. Besides this permanent broadband seismic network (PLSN) the Central Institute of Mining is running the permanent regional, short period network at the Upper Silesia area dedicated to the detailed monitoring of seismicity induced by the black coal mining activity in this area. The network consists of As the mining activity is the main source of seismicity in Poland also all mines are running underground short period networks, like for example Rudna-Polkowice copper mine seismic network consisting of 64 underground located short period seimometers. In that area, especially around the Zelazny Most: the huge post-floating artificial lake the, IGF PAS is running the local seismic array consisting of 4 short period seismometers. Besides these permanent network IGF PAN is running the portable seismic network for detailed mapping a possible natural seismic activity in selected regions of Poland. Important contribution to classical geophysical observation in the electro-magnetic field are provided by three permanent geomagnetic observatories (one at Hornsund) and supporting set of 10

  2. Re-dimensioning the Polish-German border area: Poznań as a city in a transnational cooperation space


    Tölle, Alexander


    The declining importance of national policies and the economic level as a result of globalisation as well as European integration processes compels cities to become actors on the international stage and to define their own ‘foreign policies’, which may include the establishment of transnational alliances, networks, and cooperation territories. This will be discussed using Poznań as a case study. After the fall of the Iron Curtain the city had to integrate into traditional forms of internation...

  4. Years of life lost due to lower extremity injury in association with dementia, and care need: a 6-year follow-up population-based study using a multi-state approach among German elderly. (United States)

    Zhou, Ying; Putter, Hein; Doblhammer, Gabriele


    Dementia and care need are challenging aging populations worldwide. Lower extremity injury (LEI) in the elderly makes matters worse. Using a multi-state approach, we express the effect of LEI on dementia, care need, and mortality in terms of remaining life expectancy at age 75 (rLE) and years of life lost (YLL). A population-based random sample of beneficiaries aged 75-95 years was drawn from the largest public health insurer in Germany in 2004 and followed until 2010 (N 62,103; Mean Age ± SD 81.5 ± 4.8 years; Female 71.2%). We defined a five-state model (Healthy, Dementia, Care, Dementia & Care, Dead), and calculated transition-specific hazard ratios of LEI using Cox regression. The transition probabilities as well as the YLL due to LEI were estimated. LEI significantly increased the risk for each transition, with a maximum risk for the transition from Healthy to Care (HR: 1.70, 95% CI: 1.63-1.77) and a minimum risk for the transition from Care to Dead (HR: 1.16, 95% CI: 1.10-1.22). If the elderly had LEI-history, their age-specific mortality was generally higher and their probabilities of transient states peaked at younger ages. At age 75, initially dementia-free and care-independent elderly experiencing LEI lost about 2 years of life, of which more than 90% were life years free of dementia or care need. Dementia patients lost about one and a half year, more than 60% were free of long-term care need. LEI not only casts a large health burden on care need, but is also associated with cognitive decline and shortened rLE. LEI plus dementia extend the relative life time in need of care, despite generally shortening rLE. Using the composite measure YLL may help to better convey these results to the elderly, families, and health professionals. This may strengthen preventive measures as well as improve timely and rehabilitative treatment of LEI, not only in cognitive and physically intact elderly.

  5. German risk study, phase (DRS-B)

    International Nuclear Information System (INIS)

    Werner, W.


    The first risk investigations were primarily intended to estimate the risk of accidents in nuclear power plants and to compare it with other natural risk and civilization risks. The American reactor safety study WASH 1400 and the German risk study phase A (DRS-A) gave a detailed analyses of the offsite consequences of accidents, especially the magnitude and frequency of health damage for the population. Risk investigations today are primarily used to examine the design of safety systems and to further develop the entire safety concept. Safety investigations have shown that nuclear power plants still possess safety reserves if safety systems do not operate as planned. These safety reserves can be exploited in the sense of a further development of safety by plant internal emergency measures. One purpose of risk analyses is to identify such measures and to evaluate their feasibility and effectiveness. The most important goals of the investigations in DRS-B were: Identification of vulnerabilities and possible safety improvements; determination of safety reserves during accident sequences exceeding the design limits; evaluation of plant internal emergency measures. Thus, goals in phase B compared with phase A have changed from investigations of the magnitude of damage to detailed analysis of the plant systems response under accident conditions. The magnitude of possible fission product releases is also determined in phase B. However, no new accident consequence calculations are performed. Figs and tabs

  6. Tinnitus functional index: validation of the German version for Switzerland. (United States)

    Peter, Nicole; Kleinjung, Tobias; Jeker, Raphael; Meyer, Martin; Klaghofer, Richard; Weidt, Steffi


    Different standardized questionnaires are used to assess tinnitus severity, making comparisons across studies difficult. These questionnaires are also used to measure treatment-related changes in tinnitus although they were not designed for this purpose. To solve these problems, a new questionnaire - the Tinnitus Functional Index (TFI) - has been established. The TFI is highly responsive to treatment-related change and promises to be the new gold standard in tinnitus evaluation. The aim of the current study was to validate a German version of the TFI for a German-speaking population in Switzerland. At the ENT department of the University Hospital Zurich, 264 subjects completed an online survey including the German version for Switzerland of TFI, Tinnitus Handicap Inventory (THI), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) and sociodemographic variables. Internal consistency of the TFI was calculated with Cronbach's alpha coefficient. Pearson correlation coefficients were used for the test-retest reliability of the TFI and to investigate convergent and discriminant validity between the THI and the BDI and BAI, respectively. Factor analysis was assessed using a principal component analysis with oblique rotation. The different factors extracted were then compared with the original questionnaire. The German version of the TFI for Switzerland showed an excellent internal consistency (Cronbach's alpha of 0.97) and an excellent test-retest reliability of 0.91. The convergent validity with THI was high (r = 0.86). The discriminant validity with BAI and BDI showed moderate results (BAI: r = 0.60 and BDI: r = 0.65). In the factor analysis only five factors with one main factor could be extracted instead of eight factors as described in the original version. Nevertheless, relations to the original eight subscales could be demonstrated. The German version of the TFI for Switzerland is a suitable instrument for measuring the impact of tinnitus

  7. Mutation screening of the MAPT and STH genes in Polish patients with clinically diagnosed frontotemporal dementia. (United States)

    Zekanowski, Cezary; Pepłońska, Beata; Styczyńska, Maria; Gustaw, Katarzyna; Kuźnicki, Jacek; Barcikowska, Maria


    Frontotemporal dementia (FTD) is a common neurodegenerative disorder and is connected with about 10% of all dementias. In approximately half of all FTD cases, a positive family history has been reported. To date, several mutations at the tau protein gene (MAPT) were identified causing familial and sporadic FTD. Extensive polymorphic variability at the MAPT gene has also been shown to be a risk factor in progressive supranuclear palsy (PSP). The recently described gene Saitohin (STH), located in the intron 9 of MAPT gene, was also reported to be polymorphic. In the present study 23 unrelated Polish patients with clinically defined sporadic and familial FTD were screened for mutations at the MAPT gene. No pathogenic mutations were found in the group. Several novel silent intronic and exonic mutations were identified, most of them associated with two common haplotypes. In the reported group no correlation between extended MAPT haplotype and APOE genotype was determined. There was also no observed relation between age of onset and APOE status. At the STH gene only a common polymorphic change was found. It is postulated that MAPT mutations are not connected with most of the FTD cases in the Polish population. Copyright 2003 S.

  8. Adaptation of the Four Forms of Employee Silence Scale in a Polish sample

    Directory of Open Access Journals (Sweden)

    Krystyna Adamska


    Full Text Available Background Silence is understood as a decision not to speak up in situations of observed irregularities both in productivity and ethics. The study examined the validity of the Four Forms of Employee Silence Scale (FFESS in the Polish population. The scale is a four-factor measure designed to capture differently motivated tendencies to be silent in organizations. The scale distinguishes acquiescent, quiescent, prosocial and opportunistic silence. Employee silence has been linked to many important individual outcomes: failure to react to ethical transgressions, stress and depression, and lower creativity and productivity. Participants and procedure A total of 1044 employees of various organizations working for at least six months at a given position provided the responses for the validation study. Results The results confirmed the superiority of the four-factor model shown by adequate fit indexes: The FFESS has adequate internal consistency at both the scale and item levels. The criterion-related validity of the scale was established by correlating four forms of silence with measures of emotional attitude toward organization, procedural justice, relational contract and turnover intention. Conclusions The four forms of employee silence are empirically distinct concepts in the Polish sample. The scale may be used as the measurement of individual differences. It can also serve as a tool for diagnosing a climate of silence in an organization.

  9. Planning of Polish physician workforce - Systemic inconsistencies, challenges and possible ways forward. (United States)

    Domagała, Alicja; Klich, Jacek


    Poland has the lowest number of physicians per 1000 population (2.2/1000) in the EU. This is accompanied by a considerable migration rate of Polish physicians to other EU countries (estimated at above 7%). Among other consequences, this results in waiting lists and unmet health needs. The aim of this article is an identification of the main challenges for physician workforce planning in Poland. The authors analysed national and international documents, reports, official statements, publications and statistical databases. In Poland health workforce planning is inadequate and insufficient. There is no formal structure and no strategy regarding human resource planning or regular forecasts for the health workforce, which results in many negative effects for the healthcare system. Currently the shortage of physicians in some specialties is becoming one of the most important reasons for limited access to care and lengthening the average wait time. To improve this situation operational and strategic actions should be undertaken without unnecessary delay. Effective and close cooperation between key stakeholders is needed. Health workforce planning needs to become one of the key building blocks of the Polish health system's reforms, strongly connected to the other functions of the health system. It is essential for Poland to follow available good practices in health workforce planning. Copyright © 2017 Elsevier B.V. All rights reserved.

  10. Two desmin gene mutations associated with myofibrillar myopathies in Polish families.

    Directory of Open Access Journals (Sweden)

    Jakub Piotr Fichna

    Full Text Available Desmin is a muscle-specific intermediate filament protein which forms a network connecting the sarcomere, T tubules, sarcolemma, nuclear membrane, mitochondria and other organelles. Mutations in the gene coding for desmin (DES cause skeletal myopathies often combined with cardiomyopathy, or isolated cardiomyopathies. The molecular pathomechanisms of the disease remain ambiguous. Here, we describe and comprehensively characterize two DES mutations found in Polish patients with a clinical diagnosis of desminopathy. The study group comprised 16 individuals representing three families. Two mutations were identified: a novel missense mutation (Q348P and a small deletion of nine nucleotides (A357_E359del, previously described by us in the Polish population. A common ancestry of all the families bearing the A357_E359del mutation was confirmed. Both mutations were predicted to be pathogenic using a bioinformatics approach, including molecular dynamics simulations which helped to rationalize abnormal behavior at molecular level. To test the impact of the mutations on DES expression and the intracellular distribution of desmin muscle biopsies were investigated. Elevated desmin levels as well as its atypical localization in muscle fibers were observed. Additional staining for M-cadherin, α-actinin, and myosin heavy chains confirmed severe disruption of myofibrill organization. The abnormalities were more prominent in the Q348P muscle, where both small atrophic fibers as well large fibers with centrally localized nuclei were observed. We propose that the mutations affect desmin structure and cause its aberrant folding and subsequent aggregation, triggering disruption of myofibrils organization.

  11. Pseudo-random tool paths for CNC sub-aperture polishing and other applications. (United States)

    Dunn, Christina R; Walker, David D


    In this paper we first contrast classical and CNC polishing techniques in regard to the repetitiveness of the machine motions. We then present a pseudo-random tool path for use with CNC sub-aperture polishing techniques and report polishing results from equivalent random and raster tool-paths. The random tool-path used - the unicursal random tool-path - employs a random seed to generate a pattern which never crosses itself. Because of this property, this tool-path is directly compatible with dwell time maps for corrective polishing. The tool-path can be used to polish any continuous area of any boundary shape, including surfaces with interior perforations.

  12. [The boycott against German scientists and the German language after World War I]. (United States)

    Reinbothe, R


    After the First World War, the Allied academies of sciences staged a boycott against German scientists and the German language. The objective of the boycott was to prevent the re-establishment of the prewar dominance of German scientists, the German language and German publications in the area of international scientific cooperation. Therefore the Allies excluded German scientists and the German language from international associations, congresses and publications, while they created new international scientific organizations under their leadership. Medical associations and congresses were also affected, e. g. congresses on surgery, ophthalmology and tuberculosis. Allied physicians replaced the "International Anti-Tuberculosis Association" founded in Berlin in 1902 with the "Union Internationale contre la Tuberculose"/"International Union against Tuberculosis", founded in Paris in 1920. Only French and English were used as the official languages of the new scientific organizations, just as in the League of Nations. The boycott was based on the fact that the German scientists had denied German war guilt and war crimes and glorified German militarism in a manifesto "To The Civilized World!" in 1914. The boycott first started in 1919 and had to be abolished in 1926, when Germany became a member of the League of Nations. Many German and foreign physicians as well as other scientists protested against the boycott. Some German scientists and institutions even staged a counter-boycott impeding the resumption of international collaboration. The boycott entailed an enduring decline of German as an international scientific language. After the Second World War scientists of the victorious Western Powers implemented a complete reorganization of the international scientific arena, based on the same organizational structures and language restrictions they had built up in 1919/1920. At the same time scientists from the U.S.A. staged an active language and publication policy, in

    Delahaye, M; Stieglitz, R D; Graf, M; Keppler, C; Maes, J; Pflueger, M


    In the present study, the German-language version of the Stress Appraisal Measure (SAM) by Peacock and Wong was validated in a student population. SAM is a relatively short questionnaire (28 items) that evaluates a current, stress-triggering event. The theoretical background is provided by the stress model of Lazarus and Folkman. 85 students (age: 23; 59 female, 26 male) were exposed to two stress scenarios in order to test whether they were suited to provoke stress. A factor analysis was performed and the internal consistency of the seven SAM scales was determined. In addition, the convergent validity of SAM with State and Trait Anxiety Inventory (STAI), Coping Inventory for Stressful Situations (CISS) and specific emotion scales was investigated via Pearson's product-moment correlation. The two stress scenarios were suited to evoke stress. The factor structure and the internal consistency of the individual scales, as well as the convergent validity of SAM were replicated with minor limitations in the present German version. Some items (especially from the fifth factor) were only replicated partially. SAM can also be employed in the German language version. © Georg Thieme Verlag KG Stuttgart · New York.

  14. [German Prevention Programs for Eating Disorders - A Systematic Review]. (United States)

    Pickhardt, Mara; Adametz, Luise; Richter, Felicitas; Strauß, Bernhard; Berger, Uwe


    In the past years a considerable amount of primary and secondary prevention programs for eating disorders was developed in German speaking countries. However, up to now there has been no systematic review of contents and evaluation studies. The main objective of the present systematic review is to identify and outline German prevention programs for eating disorders. This should facilitate the selection of appropriate and effective interventions for medical experts, other professionals and teachers. A systematic literature research was conducted and 22 German-language primary and secondary prevention programs were identified. Half of them were evaluated. The programs were conducted either in school, on the internet or in a group setting. The findings show that throughout almost all programs a reduction in weight and shape concerns and drive for thinness as well as an increase of (body) self-esteem could be observed in either the total sample or the high-risk sample. However, programs were inconsistently effective in reducing disordered eating behavior in the target population. All studies were effective in reducing at least one risk factor. Overall, higher effect sizes were found for secondary prevention programs than for primary prevention programs. Lastly, limitations of the studies and suggestions for future prevention efforts are discussed. © Georg Thieme Verlag KG Stuttgart · New York.

  15. [Development of pharmaceutical expenses in German private health insurance]. (United States)

    Böcking, W; Tidelski, O; Skuras, B; Kitzmann, F; Zuehlke, L


    Health Insurance costs in Germany have grown by 3 % p. a. over the last ten years and amount to approx. 280 bn EUR in 2009. While costs for stationary treatment as the largest cost category have been intensely analyzed over the past years, pharmaceutical expenses have been analyzed in less detail, mostly focusing on the Statutory Health Insurance side, even though pharmaceutical expenses have grown almost twice as much as costs for ambulant treatments. This research article therefore focuses on the question how pharmaceutical expenses in a large German private health insurance company are allocated with respect to age and indication groups, and how those have developed during the past four years. Therefore, the data of a private health insurance company with more than 600.000 customers was split into price and volume effects per age group to understand if price or volume drives the cost development. Additionally, the two largest indication groups are analyzed in detail. As a result, both price and volume effects drive an overall cost increase of 7,3 %. These effects are even stronger in older age groups. This strong cost increase is not sustainable for the German health insurance system over a longer period of time and will even further increase due to the ageing of the German population. © Georg Thieme Verlag KG Stuttgart · New York.

  16. Strain-free polished channel-cut crystal monochromators: a new approach and results

    Energy Technology Data Exchange (ETDEWEB)

    Kasman, Elina; Montgomery, Jonathan; Huang, XianRong; Assoufid, Lahsen


    The use of channel-cut crystal monochromators has been traditionally limited to applications that can tolerate the rough surface quality from wet etching without polishing. We have previously presented and discussed the motivation for producing channel cut crystals with strain-free polished surfaces [1]. Afterwards, we have undertaken an effort to design and implement an automated machine for polishing channel-cut crystals. The initial effort led to inefficient results. Since then, we conceptualized, designed, and implemented a new version of the channel-cut polishing machine, now called C-CHiRP (Channel-Cut High Resolution Polisher), also known as CCPM V2.0. The new machine design no longer utilizes Figure-8 motion that mimics manual polishing. Instead, the polishing is achieved by a combination of rotary and linear functions of two coordinated motion systems. Here we present the new design of C-CHiRP, its capabilities and features. Multiple channel-cut crystals polished using the C-CHiRP have been deployed into several beamlines at the Advanced Photon Source (APS). We present the measurements of surface finish, flatness, as well as topography results obtained at 1-BM of APS, as compared with results typically achieved when polishing flat-surface monochromator crystals using conventional polishing processes. Limitations of the current machine design, capabilities and considerations for strain-free polishing of highly complex crystals are also discussed, together with an outlook for future developments and improvements.

  18. Influence of polishing on surface roughness following toothbrushing wear of composite resins. (United States)

    Dalla-Vecchia, Karine Battestin; Taborda, Talita Damas; Stona, Deborah; Pressi, Heloísa; Burnett Júnior, Luiz Henrique; Rodrigues-Junior, Sinval Adalberto


    This study aimed to evaluate the influence of different polishing systems on the surface roughness of composite resins following procedures to simulate the effects of toothbrushing over time. Four currently available commercial composites were used to make 128 cylindrical specimens. The specimens were randomly allocated to polishing with a 1-step polisher or 1 of 3 multistep polishers (n = 8 per group). The baseline surface roughness was measured, and the specimens were submitted to 5000, 10,000, and 20,000 brushing cycles to represent toothbrushing throughout 6, 12, and 24 months, respectively. Results showed that surface roughness was influenced by the type of composite and polishing system and was not influenced by the simulated toothbrushing time. However, the surface roughness, as challenged by toothbrushing wear, was affected by the interaction among the composite, the polisher, and the toothbrushing time. The 1-step polisher produced the highest surface roughness and influenced toothbrushing wear resistance of some composites.

  19. Investigation of -308G>A and -1031T>C polymorphisms in the TNFA promoter region in Polish peptic ulcer patients. (United States)

    Sałagacka, Aleksandra; Żebrowska, Marta; Jeleń, Agnieszka; Mirowski, Marek; Balcerczak, Ewa


    Tumor necrosis factor α (TNF-α) encoded by TNFA is a key mediator in inflammation, a precursor condition for peptic ulceration. Promoter polymorphisms of TNFA that influence its transcriptional activity and TNF-α production are known. TNFA-308G>A (rs1800629) and TNFA-1031T>C (rs1799964), which are responsible for increased TNFA transcription, could influence the risk of peptic ulceration. This study aimed to investigate these polymorphisms and to evaluate their association with peptic ulcer disease and Helicobacter pylori infection in the Polish population. Gastric mucosa specimens obtained from 177 Polish peptic ulcer patients were used to conduct rapid urease tests and to assess the investigated polymorphisms by polymerase chain reaction-restriction fragment length polymorphism. Genotyping data were compared with the results obtained from healthy individuals of Polish origin. There were no significant differences in genotype and allele frequency of the investigated polymorphisms between peptic ulcer patients and healthy individuals. No associations between the frequencies of particular genotypes and alleles for both single-nucleotide polymorphisms (SNPs) and the presence of H. pylori infection in peptic ulcer patients and in subgroups of men and women with peptic ulcer disease were found. The investigated SNPs are not risk factors for either peptic ulcer or H. pylori infection development in the Polish population. The results require verification in a larger cohort.

  20. German causative events with placement verbs

    De Knop Sabine


    Full Text Available Several studies have described the semantic uses of German posture verbs, but only few have dealt with German placement verbs. The present study wants to make up for this gap. Starting from a collection of examples from the core corpora of the Digitales Wörterbuch der Deutschen Sprache (DWDS and some former studies on posture verbs, it first describes the variety of the most common German placement verbs stellen (‘to put upright’, legen (‘to lay down’, setzen (‘to set’ and stecken (‘to stick’.
