Published: February 2021

Introduction

Postpartum hemorrhage remains a leading cause of maternal morbidity and mortality worldwide. Therefore, cumulative incidence of postpartum hemorrhage and severe postpartum hemorrhage are commonly monitored within and compared across maternity hospitals or countries for obstetrical safety improvement. These indicators are usually based on hospital discharge data though their accuracy is seldom assessed. We aimed to measure postpartum hemorrhage and severe postpartum hemorrhage using electronic health records and hospital discharge data separately and compare the detection accuracy of these methods to manual chart review, and to examine the temporal trends in cumulative incidence of these potentially avoidable adverse outcomes.

Materials and methods

We analyzed routinely collected data of 7904 singleton deliveries from a large Swiss university hospital for a three year period (2014–2016). We identified postpartum hemorrhage and severe postpartum hemorrhage in electronic health records by text mining discharge letters and operative reports and calculating drop in hemoglobin from laboratory tests. Diagnostic and procedure codes were used to identify cases in hospital discharge data. A sample of 334 charts was reviewed manually to provide a reference-standard and evaluate the accuracy of the other detection methods.

Results

Sensitivities of detection algorithms based on electronic health records and hospital discharge data were 95.2% (95% CI: 92.6% 97.8%) and 38.2% (33.3% to 43.0%), respectively for postpartum hemorrhage, and 87.5% (85.2% to 89.8%) and 36.2% (26.3% to 46.1%) for severe postpartum hemorrhage. Postpartum hemorrhage cumulative incidence based on electronic health records decreased from 15.6% (13.1% to 18.2%) to 8.5% (6.7% to 10.5%) from the beginning of 2014 to the end of 2016, with an average of 12.5% (11.8% to 13.3%). The cumulative incidence of severe postpartum hemorrhage remained at approximately 4% (3.5% to 4.4%). Hospital discharge data-based algorithms provided significantly underestimated incidences.

Conclusions

Hospital discharge data is not accurate enough to assess the incidence of postpartum hemorrhage at hospital or national level. Instead, automated algorithms based on structured and textual data from electronic health records should be considered, as they provide accurate and timely estimates for monitoring and improvement in obstetrical safety. Furthermore, they have the potential to better code for postpartum hemorrhage thus improving hospital reimbursement.

Purpose

Overall survival (OS) is the most significant endpoint for evaluation of treatment benefit with checkpoint inhibitors (CPI) in cancer. We evaluated serum C-reactive protein (CRP) in non-small cell lung cancer (NSCLC) trials with atezolizumab (anti-PD-L1) as an early OS surrogate.

Methods

Serum from patients enrolled in randomized Phase II (n = 240) and Phase III (n = 701) trials of NSCLC patients (POPLAR, OAK) who progressed on prior-platinum chemotherapy, were analyzed for CRP levels over time. Patients were grouped by changes in CRP levels post-treatment as either increased (≥ 1.5 fold), decreased (≤ 1.5 fold) or unchanged (within +1.5 fold) relative to pre-treatment levels to assess association with progression free survival (PFS) and OS.

Results

Decrease in serum CRP levels at 6 weeks relative to pre-treatment were observed in patients with RECIST1.1 based complete or partial responses (CR/PR) to atezolizumab whereas patients with disease progression (PD) demonstrated an increase in CRP levels in the Phase II POPLAR study, and confirmed in the Phase III OAK study. Decrease in serum CRP as early as six weeks post treatment predicted improved PFS and OS, even in patients who were determined as stable disease (SD) in their first scan. This effect was not observed in the chemotherapy arms.

Conclusion

Modulation of serum CRP correlates with clinical outcome post-atezolizumab treatment. This routine lab test may provide utility in informing OS signals as early as 6 weeks post-initiation of therapy with CPIs in NSCLC.

Severe fever with thrombocytopenia syndrome (SFTS) caused by a species Dabie bandavirus (formerly SFTS virus [SFTSV]) is an emerging hemorrhagic infectious disease with a high case-fatality rate. One of the best strategies for preventing SFTS is to develop a vaccine, which is expected to induce both humoral and cellular immunity. We applied a highly attenuated but still immunogenic vaccinia virus strain LC16m8 (m8) as a recombinant vaccine for SFTS. Recombinant m8s expressing SFTSV nucleoprotein (m8-N), envelope glycoprotein precursor (m8-GPC), and both N and GPC (m8-N+GPC) in the infected cells were generated. Both m8-GPC- and m8-N+GPC-infected cells were confirmed to produce SFTSV-like-particles (VLP) in vitro, and the N was incorporated in the VLP produced by the infection of cells with m8-N+GPC. Specific antibodies to SFTSV were induced in mice inoculated with each of the recombinant m8s, and the mice were fully protected from lethal challenge with SFTSV at both 103 TCID50 and 105 TCID50. In mice that had been immunized with vaccinia virus strain Lister in advance of m8-based SFTSV vaccine inoculation, protective immunity against the SFTSV challenge was also conferred. The pathological analysis revealed that mice immunized with m8-GPC or m8-N+GPC did not show any histopathological changes without any viral antigen-positive cells, whereas the control mice showed focal necrosis with inflammatory infiltration with SFTSV antigen-positive cells in tissues after SFTSV challenge. The passive serum transfer experiments revealed that sera collected from mice inoculated with m8-GPC or m8-N+GPC but not with m8-N conferred protective immunity against lethal SFTSV challenge in naïve mice. On the other hand, the depletion of CD8-positive cells in vivo did not abrogate the protective immunity conferred by m8-based SFTSV vaccines. Based on these results, the recombinant m8-GPC and m8-N+GPC were considered promising vaccine candidates for SFTS.
The role of minority-language media in the construction of identity during middle childhood
Authors: Davies Helen
Published: February 2021

The ‘transition phase’ between primary and secondary school represents an important milestone in the context of identity formation. For multilingual children, questions of cultural belonging and identity can add to issues and challenges of self-representation. Giddens notes how identity construction is made up of series of narratives that formulate an ‘ongoing “story” about the self’ (: 54). Media now representing an increasingly important aspect of social life, especially amongst young people. The focus of this research is to explore how the evolution of Welsh-language children’s media production practices has formed a unique understanding of media narratives that is intrinsically connected to Welsh identity and the maintenance of a national community (cf. : 233). Framing the debate within a minority-language context, this article explores how (Welsh/English) bilingual children in Wales navigate these multiple identities in this ‘in between space’ through their engagement with Welsh-language media texts. The research will draw on findings from a dual-phased research project conducted between 2012 and 2014.
Irish outsiders: Performing Irish heritage on the streets of New York
Authors: Caulfield Mary P.
Published: February 2021

This article analyses how the Tenement Museum at 97 Orchard Street in Lower Manhattan uses immersive techniques to provide visitors with an opportunity to engage with nineteenth- and early twentieth-century immigrant experiences. My specific focus is the apartment tour entitled, Irish Outsiders, a living history installation curated as part of the Museum’s Hard Times exhibit that recreates the cramped apartment of Joseph and Bridget Moore, real-life residents of 97 Orchard Street in 1869. The Moores left an Ireland traumatized by the Great Famine only to arrive at the challenges of New York City immigrant living. This immersive recreation of Joseph and Bridget Moore’s apartment staged for a Catholic wake links this specific Irish immigrant experience with that of loss, suffering, poverty and trauma. Drawing on Alison Landsberg’s concept of ‘prosthetic memory’ alongside frameworks of heritage performance, this article examines the Irish Outsiders as an immersive performance curated to reflect and shape the narrative tropes essential to the Irish immigrant experience implicit within an Irish-American heritage identity.
‘Irish … but nothing Irish’: The performance of Ireland on the British colonial stage
Authors: Gannon Seán William
Published: February 2021

In a perceptive essay on Scottish national and imperial identity, Richard J. Finlay framed what he termed the ‘transplantation of “Highlandism”’ to the colonies through Scottish societies, Highland dancing clubs and Burns nights as the ‘performance of Scotland’ overseas. Using a range of documentary archival sources and written and oral personal testimonies, this essay applies Finlay’s idea to Irish communalization in the twentieth-century British dependent empire. The transient ‘imperial Irish’ diasporas that Irish soldiers, settlers, colonial servants and missionaries comprised formed an integral and generally indiscernible part of the British ruling class. However, Irishness was spatialized in colonial life through Irish clubs, societies and St Patrick’s Day celebrations which enacted a ‘stage’ performance of Ireland based on ritualized caricature and trope. This performance was also thoroughly imperialized and was directed with performative purpose. It worked to ecumenize the social, religious and political ‘varieties of Irishness’ that co-existed in British colonial life; ‘imperial Irish’ diasporas represented the heterogeneity of twentieth-century Irish identities and these performances created depoliticized spaces which emphasized commonalities rather than contrasts. Inter-accommodation of these disconsonant identities was required in the colonies where ‘British’ ethnic, political and religious differences had to be submerged to preserve the more critical distinction between colonizer and colonized on which the empire’s legitimacy and sustainability depended. The colonial performance of Ireland also served to demonstrate that Irishness and loyalty to the Crown and empire were not, by definition, dichotomous: the non-threatening, imperialized image of Irishness that they presented countered the enduring trope of the Irish as ‘natural subversives’.
Main Challenges of EMI at the UCLM: Teachers’ Perceptions on Language Proficiency, Training and Incentives
Authors: Nieto Moreno de Diezmas Esther , Fernández Barrera Alicia
Published: February 2021

English-medium instruction (EMI) has become commonplace in Higher Education Institutions (HEIs) in Spain and in many other countries, being implemented as a strategy to increase the competitiveness and attractiveness of universities at the international level. The present article investigates the stances of lecturers involved in various internationalization programmes in regard to the challenges that EMI inception and implementation entails, such as language and content integration, English proficiency of teachers and students, teachers’ drives, teacher training needs and institutional support, among other issues. To gain a more comprehensive insight into the development of EMI, data were collected by means of semi-structured interviews with three separate groups of lecturers: (i) EMI practitioners, (ii) lecturers interested in EMI and (iii) lecturers from the Department of Modern Languages, experts in second language acquisition (SLA) and bilingual education. The results showed that the implementation of EMI at the University of Castilla-La Mancha (UCLM) is still in its infancy and there are several areas for improvement such as (i) the approval of a multilingual language policy that includes a specific and legally-binding protocol for lecturer recruitment and commitment in the programme, and (ii) the design of a more comprehensive teacher training plan offering accreditation to enter EMI and supporting effective implementation by means of in-service courses.
The Phenomenon of Underage Motorbike Riders in Junior High School Students: A Critical Review of Juvenile Delinquency
Authors: Lutfi Azri Zulfikar
Published: February 2021

Motorbike use by students who are under the age of 17 years is an act of infringement. It is stated in Article 281 of Law Number 22 Year 2009 regarding Traffic and Road Transportation. Traffic violations is often done by junior high school students. User behavior motorbikes under the age is a form known as juvenile delinquency. In this study, researcher took samples at two schools namely SMPN 1 Bambanglipuro and SMPN 2 Sanden, Bantul, because researcher saw a lot of students who ride the motorbike to go to school. To examine this phenomenon, researchers used quantitative research methods by taking 394 students as respondents. Associated with the phenomenon of motorbike users under age, this paper focuses on a form of parenting from their parents and motorbike users under age as the dependent variable and independent variables. In this study, the researcher used chi square test to look at the relationship between the independent variable and the dependent variable. This paper uses the concept of social control theory of Travis Hirschi (2007) to understand how such behavior could occur. Indeed the respondents knew what they were doing was a violation, but because of the environment that tends to allow these actions to make them feel safe. As the results obtained in this study, the high number of motorbike users in this study, due to several reasons, namely, less strict parents of children, lack of maintenance performed by local traffic police, and the lack of public attention to such behavior.

Impact of exogenous alpha tocopherol on peanut seedlings (Arachis hypogaea L.) treated by norflurazon
Authors: Manaa Imene , Djebbar Reda , Abrous-Belbachir Ouzna
Published: February 2021

Norflurazon 100 µM alone or in combination with α-tocopherol (0.25 mM) was applied in pre-emergence of peanut seedlings (Arachis hypogaea L.). Norflurazon treatment allowed to partially or totally photobleach plants which were noticeably smaller than the control. Norflurazon impaired the photosynthetic activity by decreasing photosynthetic pigments (carotenoids and chlorophylls) and by reducing quantities of soluble sugar. The determination of malondialdehyde (MDA) showed that its content was higher in treated plants in relation with enhancement of reactive oxygen species by the herbicide and decreased the endogenous α-tocopherol. The addition of exogenous α-tocopherol reduced the damage done by the herbicide at the membrane level because of the MDA content was less important than in norflurazon treated seedlings. Furthermore, the norflurazon decreased the glutathione S-transferase (GST) activity in the leaves and the roots of peanut seedlings, while it increased the level of reduced glutathione. This activity decreased even more with the application of exogenous α-tocopherol in combination with the herbicide. The herbicide alone or in association with the antioxidant α-tocopherol increased ascorbic acid content. The supplementation of α-tocopherol did not decrease the phytotoxicity of norflurazon although we observed a decrease in MDA content.

Published: February 2021

Lagochilus is a genus with ten taxa (species, subspecies and variety) in Iran, which nine of them are endemic. This is the first micromorphological investigation of this genus. Micromorphological features of trichomes on the stems, leaves and calyces, and also pollen morphology of 19 populations were investigated by scanning electron microscopy. Two types of trichome (glandular and non-glandular) including 14 forms were described. Here, among the non-glandular trichomes, cell number and size of trichomes are considered as valuable characteristics, while the glandular trichomes are observed as stalked, sessile and peltate. Lagochilus pollen grains are tricolpate and small to medium sized. The basic shape of the pollen grains in most taxa is prolate, however prolate-subprolate pollen grains was recorded for L. aucheri ssp. aucheri var. aucheri 2. Four types of exine sculpture patterns were distinguished: bireticulate, reticulate, microreticulate and incomplete reticulate. Quantitative and qualitative characteristics were examined by multivariate analysis. The results indicated that the studied taxa were separated from each other; however varieties of L. aucheri did not grouped together. The results support the existence of known varieties in L. aucheri. In general, our investigations reveal the usefulness of micromorphological characteristics in taxon delimitation at the specific and infraspecific levels.

The leaves of T. alternifolia is hypostomatic with paracytic stomata, uniseriate epidermis made up of thin-walled parenchymatous cells covered by thin cuticle on both adaxial and abaxial surfaces. The hypodermis comprises of angular collenchyma cells. Mesophyll is dorsiventral containing silica bodies and vascular bundles are bicollateral. The petiole is flattened adaxially and arch-shaped abaxially with a uniseriate epidermis covered by a thin cuticle. The hypodermis is 7-8 layered angular collenchyma cells consisting of laticifers and parenchymatic, cortical layers consisting of silica bodies and thick-walled fibers and U-shaped bicollateral vascular bundles. Secondary growth in stems is characterized by the formation of periderm and thick-walled fibers in the vascular tissues. Bicollateral vascular bundles are covered by sclerenchymatous patches, parenchymatous cortex and pith consist of fibers, laticifers and silica bodies. The root possess unicellular root hairs, compactly arranged thin-walled uniseriate epidermis, 16-18 layered cortex containing silica bodies and fibers, indistinct endodermis, radially arranged vascular bundles and 14-16 arched xylem. Pitted water-storage cells are present in the conjunctive tissue. Lignin deposition was observed in the root stelar region and pith is absent.

Published: February 2021

Hedera, with 12 extant species, is a genus of evergreen climbers native to Europe, north Africa, and south Asia. In this study, the micromorphological, anatomical structure and molecular evidences of 11 populations from two species of Hedera (H. helix and H. pastuchovii) have been considered to evaluate the relationships in Hedera. In total, seven quantitative and qualitative characters of pollen were selected and measured. Based on this study, the anticlinal wall and surface sculpturing of seed support for separation of two species of Hedera. Micromorphology of epidermis illustrated two types of epidermal cells: puzzle-shaped and polygonal cells. Using nuclear (nrDNA ITS) marker, we reconstructed phylogenetic relationships within two species of Hedera. This data set was analyzed by phylogenetic methods including Bayesian inference, maximum likelihood, and maximum parsimony. In phylogenetic analyses, all members of two species formed a well-supported clade (PP = 1; ML/BS = 100/100) and divided into two major clades (A and B). Neighbor Net diagram demonstrated separation of the studied populations. The results showed that these taxa differ in taxonomically important micromorphological, anatomical and molecular characteristics and these data provide reliable evidence for separation of these two species.
The Effect of Caffeine on Athletic Performance
Authors: Hussain Nabeel
Published: February 2021

Hypothesis:The intake of caffeine can increase physical performance during athletic activity

Methods:A search for primary sources was done using PubMed with MeSH terms. The search was limited to randomized controlled trials that were published between 2015 and 2020. After application of inclusion and exclusion criteria, seven articles were selected for this literature review.

Results:Of the seven randomized controlled trials selected, six demonstrated caffeine ingestion led to a statistically significant increase in physical performance. One of the randomized controlled trials found no statistically significant relationship between caffeine and run timings. The level set for statistical significance for this literature review was set to p < 0.05.Conclusion: With regards to the results of the selected studies, caffeine was shown to have ergogenic activity and was able to increase physical performance during exercise and sporting competition through multiple mechanisms. Further research should be done with greater sample sizes to determine the effect of rate of metabolism on caffeine activity and to compare caffeine responders and non-responders.

Published: February 2021

Reclaimed airports usually have fragile geological structures and are susceptible to the uneven ground settlements caused by filling-material consolidation, underground construction, and dynamic loading from takeoff and landing of aircrafts. Therefore, deformation monitoring is of great
significance to the safe operation of reclaimed airports. This study adopts an improved permanent-scatterer interferometric synthetic-aperture radar strategy to map the spatiotemporal deformation of Shenzhen Bao'an International Airport in China using ascending and descending Envisat/ASAR
data acquired from 2007 to 2010 and Sentinel-1 data from 2015 to 2019. The results show that uneven settlements of the airport concentrate in the new reclaimed land. Then we explore the settlement characteristics of each functional area. Furthermore, we separate out the dynamic-load settlement
of runway No. 2 and confirm the settlements caused by dynamic load. This study provides new ideas for studying deformation in similar fields, and technical references for the future construction of Shenzhen Airport.

Published: February 2021

The urgency of creating appropriate, high-resolution data products such as impervious cover information has increased as cities face rapid growth as well as climate change and other environmental challenges. This work explores the use of fully convolutional neural networks (FCNNs )—specifically
UNet with a ResNet-152 encoder—in mapping impervious surfaces at the pixel level from WorldView-2 in a mixed urban/residential environment. We investigate three-, four-, and eight-band multispectral inputs to the FCNN. Resulting maps are promising in both qualitative and quantitative
assessment when compared to automated land use/land cover products. Accuracy was assessed by F1 and average precision (AP) scores, as well as receiver operating characteristic curves, with area under the curve (AUC ) used as an additional accuracy metric. The four-band model shows the highest
average test-set accuracies (F1, AP, and AUC of 0.709, 0.82, and 0.807, respectively), with higher AP and AUC than the automated land use/land cover products, indicating the utility of the blue-green-red-infrared channels for the FCNN. Improved performance was seen in residential areas, with
worse performance in more densely developed areas.

Published: February 2021

As the public IPv4 address space has already been depleted, the full deployment of IPv6 became indispensable, especially for service providers, as it offers a sufficient address pool. However, the ongoing IPv6 transition seems to be a lengthy task because of the numerous challenges it faces. Therefore, it is expected that IPv4 and IPv6 will coexist for a long time. Consequently, many transition technologies have been developed for this purpose. Several research papers have conducted performance analysis for a number of these transition technologies and even compared them based on some measuring metrics like RTT, throughput, jitter, packet loss, and so on. This paper reviews the results of these papers, discusses their findings, and gives some guidelines fora feasible benchmarking methodology.
THE STATUS OF PSYCHOLOGY AS A SOCIAL SCIENCE AND THE VALUE OF STUDIES ON THE QUALITY OF LIFE Status psychologii jako nauki społecznej a wartość badań nad jakością życia

Published: February 2021

Despite the vast knowledge concerning factors determining the level of quality of life accumulated in social sciences there are still difficulties with its application to improve human existence. Limited possibilities of rational moulding of this feature may be traced back to the dichotomous approach to social and psychological determinants of the course of human life (the conflict between psychological individualism and sociological holism). Resorting to dimensional thinking may be a solution to this problem. By analysing various functions played by imagination in the lives of both individuals and communities it has been demonstrated how imagination can be used to improve the quality of life.

WORK – FAMILY CONFLICTS AND JOB-RELATED SUBJECTIVE WELL-BEING – A MEDIATING ROLE OF WORK ENGAGEMENT
Authors:   SWPS Uniwersytet Humanistycznospołeczny, Wydział Zamiejscowy w Poznaniu, Zalewska Anna
Published: February 2021

Introduction: The aim of this study was to analyze relations between work-family conflict (WFC) and family-work conflict (FWC) and job-related subjective well-being (job satisfaction, positive – PA and negative – NA affects at work).considering work engagement as variable that can mediate these relationships. Method: 114 employees (31.6% men) aged 25-55 (M=35.39; SD=7.42) completed a set of questionnaires: Work-Family and Family-Work Conflicts, Utrecht Work Engagement Scale (UWES-17), Job Affect Scale, and Job Satisfaction Scale. Results: All variables were related each to other. WFC and FWC predicted NA and work engagement and through it job satisfaction and PA, and then NA. Work engagement effect was stronger than conflicts effect – higher work engagement predicted higher job satisfaction and PA, and lower NA. When work engagement was controlled the job satisfaction- PA relation was ns. Conflict-work engagement interaction effects were not significant. Conclusions: Relationships are similar regarding both FWC and WFC. Work engagement do not moderate “conflict – job-related subjective well-being” relations but it mediates them. Conflicts increase NA and decrease work engagement and through it job satisfaction and PA. Work engagement enhances job-related subjective well-being protecting against adverse conflict impacts. Job satisfaction-PA relation is spurious – it results from work engagement impact on both variables. Key words: work-family and family-work conflicts, work engagement, job satisfaction, positive affect, negative affect, mediator, moderator

The analysis of literature concerning of theory of values hierarchy by M. Rokeach and model of the quality of life by B. Mróz allowed to creation of research hypotheses. Model MOA, the Sense of Life Quality Questionnaire, and the Value Scale were used in order to raise data base for a verification which came from 126 students. The main goal of the work was confirmed and it states that the level of quality of life differentiates the students pedagogic and electronic in terms of the sense of life quality and the hierarchy of values. Results analysis showed that the strongest predictor of the general sense of life quality were variables such as: „health”, „providing financial support for the family” and „mature love”. The research implications that contained possible preventive activities and the possibilities of future research in this area are also important aspects of the work.

BASIC PSYCHOLOGICAL NEEDS SATISFACTION MEDIATES BETWEEN CORE SELF-EVALUATIONS AND WORK SATISFACTION
Authors:   Instytut Psychologii, Uniwersytet Opolski, Opole, Walczak Radosław
Published: February 2021

The article presents the verification of a mediation between core self-evaluations (Judge, Locke, Durham, 1997) and work satisfaction, by the means of satisfaction of basic psychological needs at work (Deci et al., 2001). On a two multi-source cross-sectional samples (n1=977, n2=573), using path analysis, it was shown that both the structure of psychological needs at work is of three-factor character and that the postulated mediation relation can be confirmed. The results can be interpreted as a suggestion to look at the role of mediators between the dispositional variables such as core self-evaluations and job satisfaction. Key words: job satisfaction, basic psychological needs at work, core self-evaluations

The article is a report on our own research concerning how spouses who do not take over parental roles assess their family. The study aimed to search for a relationship between evaluating one’s family and life/marital satisfaction and attitudes towards children among spouses who do not undertake parenting. The study was carried out from a developmental perspective. The research group consisted of 76 married persons in their early adulthood. The participants postponed taking on parental roles for a specified time or declared voluntary childlessness. The analysis showed that significant relationships exist between family assessment and: life satisfaction (in men), marital satisfaction (in women), and attitudes towards children (in both genders). The research revealed that both the quality of family relationships and gender play an important role in shaping procreative attitudes of spouses who do not take parental roles.

The situation of mental crisis and psychiatric hospitalization is a difficult one, which may be described in the category of stress that affects individuals’ subjective well-being. Also the post-discharge period, the time of recovery, is related to the necessity of coping with many difficulties-stigma, treatment, occupational problems. The aim of the study was to assess the levels of perceived distress during the time of psychiatric hospitalisation and in post-discharge period, coping strategies, self- efficacy and also associations of these variables with subjective well-being in people who prepare to the role of peer support workers. The pilot study covered a group of 35 subjects -participants of one of the first realised in Poland workshop for peer support workers. The following questionnaires were used: Psychological Well-Being PWB, The General Self-Efficacy Scale GSES, Distress Thermometer DT, Brief-COPE. The results point to the existence of the associations of subjective well-being in future peer support workers and their difference of distress appraisal between the time of crisis and the time of recovery, self-efficacy and the complex set of coping with stress strategies. The research demonstrates that further empirical explorations are justified of the subjective well-being and coping of individuals after a psychiatric hospitalization crisis, who wish to help other mental disorder sufferers.

The R-W test is a tool examining the speed and accuracy of thinking used in labor psychology. It is described as a tool „filled with the intellectual component”, however, there is no validation data in the literature confirming that the R-W test exam some aspect of intellectual abilities. To fill this gap, validation studies were conducted. In the first one, conducted on a group of drivers (N=105), the R-W test relationship with the complex reaction time, attention, as well as the participants level of education were revealed. In study 2 conducted on a group of students (N=150) the relationship between the R-W test and fluid intelligence, perceptivity and attention, as well as anxiety as a trait and as a state were revealed. The obtained results confirm our assumptions that performing the R-W test requires the use of fluid intelligence resources.

This study was conducted in order to verify the role of social support and coping strategies as moderators of the relationship between perceived stress and the subjective well-being of transgender people, which is lower than cisgenders’ people. 355 people took part in this study (124 transgender people and 231 cisgender people) between age of 18 and 53. Subjective well-being has been operationalized using the Satisfaction With life Scale SWLS. Measurement of the perceived stress was made using the Perceived Stress Scale PSS-10. Coping strategies were examined using the Mini-COPE inventory. Additionally, two subscales of the Berlin Social Support Scales BSSS were used to measure received and perceived social support. Transgender people scored on the SWB scale significantly lower than cisgender people. Received and perceived social support did not turn out to be a significant moderators of the relationship between perceived stress and the subjective well-being. Only one of the coping strategies turned out to be an significant moderator of this relationship – venting of emotions. Key words: transgenderism, perceived stress, quality of life, social support, coping strategies

The main objective of this paper is exploration of mechanisms clarifying work behaviors commonly known as bad. Researchers call it Counterproductive Work Behaviors (CWB). Understanding of those processes can lead to theoretical conclusions that could help to minimize those behaviors in organizations. Presented research (N=138) was conducted to verify: 1) Goal Achievement Motivation, Dark Triad and Work Engagement as Counterproductive Work Behaviors predictors, 2) moderating role of Dark Triad and Work engagement for Counterproductive Work Behaviors. Additionally, we checked Narcissism as a mediator of Psychopathy and Machiavellianism with Counterproductive Work Behaviors. We used: Utrecht Work Engagement Scale (Szabowska-Walaszczyk, Zawadzka & Wojtaś, 2011), AGQ-r – Achievement Goal Questionnaire (Lipowska, 2016), CWB-c – Counteproductive Work Behavior – checklist (Baka, Derbis & Walczak, 2015) and Parszywa Dwunastka Questionnaire (Czarna & Jonason, 2016). Research was performed on a group of office workers. We assumed that this type of work can be connected with higher intensity of Counterproductive Work Behaviors. Results, that are discussed in the final part of this paper, were mostly consistent with hypothesis. Key words: counterproductive work behaviors, Dark Triad, achievement goals, work engagement

Fibromyalgia is a common chronic pain disorder characterized by widespread pain and tenderness in mostly tendon attachments with unknown etiology. Treatment of fibromyalgia is mainly drug and other treatments, especially cognitive behavioral therapy and exercise therapy combined. However, drugs for fibromyalgia have, in general, broad adverse effects. Thus, an unmet medical need remains for effective therapeutic modalities for fibromyalgia. We have recently developed a new magnetic medical device (project code “AT”) that has alternating magnetic fields and stimulates the affected area for pain relief. In the pilot study, AT treatment (twice daily for 10 min) tended to reduce the mean NRS (Numerical Rating Scale) pain score. Moreover, we demonstrated long treatment (30 min) suppressed LPS-induced (Lipopolysaccharide-induced) mRNA IL-6 expression compared with 10-min treatment in vitro. These results assumed that long treatment has high efficiency. To evaluate the safety of long time (120 min/day) AT treatment for 12 weeks. Single center, prospective, open-label, single-arm, intervention study to demonstrate the safety of long-time use of AT in 5 healthy Japanese volunteers to 12 weeks. During the intervention period, all of the adverse events were measured. The represents of AT treatment was 99.8 % in 5 subjects. The average and median exposure time of the study device was 135 min per day and 132 min per day, respectively. There were 3 nonserious adverse events and no serious adverse events during this study. This study tested long-time use of AT among 5 healthy subjects in Japan and showed that it did not pose any significant safety concerns. Because there are in-house in vitro data suggesting that the longer exposure of AT achieves a greater effect, the result of this study may allow us to conduct further studies to confirm more effectiveness and safety of long-time use of AT in a larger scale of clinical trial.

Objective: To develop and validate clinical prediction models for the development of a nomogram to estimate the probability of patients having coronary artery disease (CAD).

Methods and Results: A total of 1,025 patients referred for coronary angiography were included in a retrospective, single-center study. Randomly, 720 patients (70%) were selected as the development group and the other patients were selected as the validation group. Multivariate logistic regression analysis showed that the seven risk factors age, sex, systolic blood pressure, lipoprotein-associated phospholipase A2, type of angina, hypertension, and diabetes were significant for diagnosis of CAD, from which we established model A. We established model B with the risk factors age, sex, height, systolic blood pressure, low-density lipoprotein cholesterol, lipoprotein-associated phospholipase A2, type of angina, hypertension, and diabetes via the Akaike information criterion. The risk factors from the original Framingham Risk Score were used for model C. From comparison of the areas under the receiver operating characteristic curve, net reclassification improvement, and integrated discrimination improvement of models A, B, and C, we chose model B to develop the nomogram because of its fitness in discrimination, calibration, and clinical efficiency. The nomogram for diagnosis of CAD could be used easily and conveniently.

Conclusion: An individualized clinical prediction model for patients with CAD allowed an accurate estimation in Chinese populations. The Akaike information criterion is a better method in screening risk factors. The net reclassification improvement and integrated discrimination improvement are better than the area under the receiver operating characteristic curve in discrimination. Decision curve analysis can be used to evaluate the efficiency of clinical prediction models.

This study aims to determine the relationship between facial physiognomy, body shape, and visualization of animated film character designs. Characterization in an animated film is inseparable from the characters who are placed to fulfill the film’s role. In the creation of physiognomy and body shapes can be combined as an approach to design. The characters are modified through simplifications in the form of cartoons. This is done so that the visualization of the character gets closer to the role added, in addition to emphasizing the characteristics of one character to another. Even in animated films, characters become important elements to direct the understanding of stories. The approach used is interdisciplinary, given that in characters there is a merging of visual elements that need to be approached using different theories. The combination of theories used is personality theory through somatotype to find characters through body shapes, physiognomy from Ar-Razi and ming xiang to obtain character traits and the theory of simplifying shapes into cartoons. The result is a match between the characters played by the three reference elements. The interesting thing that was found was the application of different physiognomy between one character and another to reinforce the characteristics. So that in the film, these figures can represent roles, which are human presentations in real life.
