Published: December 2019

The aim of the present study was to describe the demographic characteristics of patients diagnosed with primary brain tumor, the clinical features and prognostic indicators of disease progression and treatment they received.Methods: A retrospective descriptive study was conducted on a convenience sample of 47 patients who attended the radiotherapeutic department of General Hospital of Athens over three years, from May 2011 until May 2014.For analysis used the statistical program SPSS 18.0.Results: 59.6% of patients were male and 40.4% of patients were between 61 and 69 years. 85.1% of patients had glioblastomamultiforme and meningioma 8.5%. 57.5% of patients with glioblastomamultiforme were men and 50.0% of patients with meningioma. It was found that the patients with grade I-III were considerably higher percentage between 61 and 69 years as compared to patients with grade IV (p = 0,021). Patients with grade IV underwent chemotherapy significantly higher rate compared with patients with grade I-III. No significant difference was found in the course of radiotherapy among patients with grade IV and patients with grade I-III. Differed significantly Ki-67 among patients with grade IV and of patients with grade I-III patients with grade IV were higher Ki-67.Conclusion: Glioblastoma multiforme (GBM) is the most frequently diagnosed intracranial malignant tumor in adults. Typical treatment for glioblastomas, with surgical resection followed by radiation and chemotherapy with temozolomide and anti - angiogenic therapy bevacizumab , have significantly improved the overall survival.

Published: December 2019

Introduction: Improvement of the quality of health care and patients' satisfaction during their hospitalisation depends on many interconnected factors.Aim: This research study intends to investigate four aspects of the nursing environment (autonomy, relationships between doctors and nurses, commanding support and checking working conditions) and the effect they have on nursing care.Material and Methods: The study sample consists of 127 public hospital nurses with a mean age of 45 years (SD = 6.8 years). The questionnaire which was used was based on the revised version of NURSING WORK INDEX-REVISED (NWI-R). Data analysis was performed by the statistical package SPSS 19.0.Results: Of the total sample, 72.4% of participants agree that supervisors support their staff and 60.6% thinks that there is support from nurses for the decisions of their colleagues. Also 10.3% agree that there are enough resources that allow them to spend time with patients, while 65.3% claims that they spend their personal time on different duties. Furthermore, correlation was detected among the aspects of autonomy, relationships between doctors and nurses and ''Control over the practice setting''. The workplace affects the autonomy's percentages (p<0.020), control of working conditions (p<0.004) and was related to organisational support (p<0.020). According to the above, nurses due to lowest direction's rating have less satisfaction from their research (p<0.004).Conclusion: The nurses’ job satisfaction is significantly related to the ‘’autonomy’’ factor and affects the quality of care provided to the patient. By investing in actions and practices that increase autonomy ,improve the control of working conditions as well as the cooperation between nurses and doctors and by increasing organisational support for the employee, there is significant improvement of the quality of nursing care and increased job satisfaction.

Published: December 2019

Introduction: Pain accounts for 40% of all patients admitted to the Emergency Department (ED). The most common cause of pain is abdominal pain, which accounts for 8%. In contrast to the international guidelines, pain is under-treated making the phenomenon of oligoanalgesia apparent.Aim: The purpose of this study was to explore the incidence of analgesia in patients admitted to the ED suffering from acute abdominal pain. Material and Method: This is a descriptive cross-sectional study. The studied sample consisted of 197 patients, who admitted to the ED of a General Hospital of Athens, Greece with reported symptom: acute abdominal pain. For data collection, a special designed form of closed-type questionnaires was used. Data analysis was performed by using the Statistic Package for Social Sciences (SPSS) statistical packet ver.19.Results: Out of the total number of patients admitted to ED with reported abdominal pain, 74.6% received analgesia and the mean time of analgesia administration during ED admission was 46.43 minutes. The mean pain intensity at the first time point measurement was 7.16 and at the second one was 4.04, according to pain recording scale (0-10 scale). Non-opioid anti-inflammatories (52.3%), non-steroidal analgesics (22.8%) and opioids (9.1%) were mainly administered patients during their ED stayConclusions: Despite the published international guidelines which refer to analgesia time and type, pain and especially abdominal pain, is under-treated. The key to tackling oligoanalgesia is to educate health professionals.
A study on metaphors used by female teachers to describe their work-related stresses and psychological exhaustion: reflecting on potential interventions
Authors: KAVIANI HOSSEIN , Alshaer Hanouf 
Published: December 2019

Aim of the studyThe past three decades saw the research development in the field of metaphoric thinking that laid a foundation within cognitive science on which culturally embedded concepts and action tendencies can potentially be explored. The present study aimed to identify female teachers’ perceptions of work-related stresses and emotional challenges in Saudi Arabia.Subject or material and methodsUsing a qualitative methodology, a semi-structured interview along with two metaphor inventories, namely Stem-Sentence Test (SST) and Metaphor Inventory (MI) were employed to collect data. Forty female teachers participated in this study; 20 newly employed (NE) teachers and 20 teachers who have currently applied for early retirement (ER). Thematic analysis was used to categorise participants’ metaphorical expressions and interpret the extracted themes.ResultsThe findings show that there are differences and similarities in metaphors generated by the two groups. ER teachers compared with NE participants tended to have more pessimistic views, negative thoughts and unpleasant feelings towards the teaching profession. They expressed metaphors connected to circular, incomplete and dark thematic dimensions. However, both groups produced metaphors linked with restricted and harmful subthemes which implies the inherent systemic shortcomings in the teaching environment for female teachers.DiscussionThe findings might suggest clinical and therapy-related implications.ConclusionsCognitive and behaviour change through changing metaphors will be reflected upon.
How to support patients with BRCA genetic mutation? Research review.
Authors: Michałowska Sylwia 
Published: December 2019

Aim of the studyAccording to research conducted so far, the detection of a genetic mutation that increases the risk of developing cancer may be associated with feelings of discomfort, anxiety and apprehension, so it is important to know the needs and expectations externalized by those patients who face the challenge of coping with information about cancer risk. This analyzes the results obtained on this subject in recent studies.Subject or material and methodsThe results of 11 studies conducted in the years 2000-2018 were analyzed. To achieve this aim, the EBSCO, PubMed, PsychARTICLES and MEDLINE databases were searched through.ResultsThe results obtained show that both male and female carriers of BRCA mutations have specific support needs. They usually look for valuable content, including information on the procedure for conducting the genetic test and the consequences of obtaining a positive result. Social as well as therapeutic support are also significant. Patients who participated in psychotherapy assessed this form of help as valuable and necessary, especially in relation to the decision making process regarding surgical treatment.DiscussionSupport programs for patients with BRCA mutations implemented in different countries have a chance to become an inspiration for introducing similar solutions in Poland.ConclusionsThis could possibly lead to increased patient involvement in preventive activities or could contribute to the reduction of anxiety or distress that results from having a genetic mutation.

Published: December 2019

The present research was developed aiming to study macroscopically the effects of karstification that, over the time, affected significantly the carbonated massif in Khózuè, Cheringoma Plateau (Mozambique). The research was carried out from a field study (collecting samples and photos) for a period of one week, in May of 2017, in Khózuè. During the field work, evidences found in nature were recorded as well as, the mode of occurrence of several structures (caves, dolines and speleothems). The karstification in the study area that occurs in the Cheringoma Formation (from Middle Eocene) was greatly conditioned by fractures which influenced the process and formation of caves and dolines. These structures tended to follow morphological patterns depending on guide fractures orientation allied to their genesis and creating, in certain cases, dolines with a cross morphology. In addition to caves and dolines, karstic activity in the Cheringoma Formation massif also created other structures, especially speleothems, which are not widespread, and also preservation/fossilization of plant remains by mineralization. Chemical weathering chemical weathering, but especially internal geodynamic phenomena transformed the Khózuè massif one karst region with peculiar characteristics. ResumoEste trabalho foi desenvolvido com o objetivo de estudar macroscopicamente os efeitos da carstificação que, com o tempo, afetaram significativamente o maciço carbonatado de Khózuè, no platô de Cheringoma (Moçambique). A pesquisa foi realizada a partir de um estudo de campo (coleta de amostras e fotografias), em 2017, em Khózuè. Durante as atividades de campo, foram analisadas as estruturas encontradas na área de estudo, tal como a ocorrência de falhas, cavernas, dolinas e espeleotemas. A carstificação na área de estudo, associada á Formação Cheringoma (do Eoceno Médio), foi muito influenciada por falhas. Estas favoreceram a formação de cavernas e dolinas. Essas estruturas tenderam a assumir padrões morfológicos condicionados pela orientação de falhas. Em certos casos, as falhas deram origem por exemplo a dolinas em forma de cruz. Além de cavernas e dolinas, a atividade cárstica no maciço da Formação Cheringoma deu lugar também a outras estruturas, como por exemplo, espeleotemas encontrados em apenas alguns locais e a processos de preservação/fossilização por mineralização de restos vegetais. A meteorização química, mas sobretudo fenómenos de geodinâmica interna transformaram o maciço calcário de Khózuè uma região cárstica com características peculiares. Palavras-chave: Karstificação.

rocks of the Cuiaba Group, into the inner portion of the Paraguay Belt (Brazil). They occur in a belt (~1200 m) where the host rocks are graphitic phyllites, metadiamictites, metasiltites and sandstones metamorphosed in greenschist facies. In these deposits gold occurs free or included in pyrite related to three types of quartz veins, parallel to Sn (V1), parallel to Sn+1 (V2) and orthogonal (V3) which are rich in gold. The study of outcrops in regional profiles, open mines for gold exploration and drilling holes in the Cangas-Poconé alignment indicate that the preferential location of gold mineralization at (Cangas Facies) is related to the existence of strong lithological control of the mineralizations.The Cangas facies present low permeability of rhythmite, structural arrangement of permeability barriers S0 and S1 at high angle with respect to the fluid migration path and mainly the presence of ferruginous levels acting as geochemical barriers for precipitation of metals in solution in the fluid. The knowledge that gold concentration is related to sedimentary control is important for regional exploration and is a guide for local miners. CONTROLE LITOSTRATIGRÁFICO DOS DEPÓSITOS AURÍFEROS DO LINEAMENTO CANGAS-POCONÉ (CINTURÃO PARAGUAI): IMPLICAÇÕES PARA A EXPLORAÇÃO REGIONAL ResumoOs depósitos de Cangas-Poconé estão hospedados em rochas metassedimentares do Grupo Cuiabá, na porção interna do Cinturão do Paraguai (Brasil). Eles ocorrem em um cinturão (~ 1200 m), onde as rochas hospedeiras são filitos, metadiamictitos, metasiltitos e arenitos grafitados, metamorfoseados em fácies de xisto verde. Nesses depósitos, o ouro ocorre livre ou incluído em pirita relacionada a três tipos de veios de quartzo. O estudo de afloramentos em perfis regionais, minas abertas para exploração de ouro e perfurações no alinhamento Cangas-Poconé indica que a localização preferencial da mineralização de ouro em (Cangas Facies) está relacionada à existência de forte controle litológico.O conhecimento de que a mineralização de ouro está relacionada ao controle sedimentar é importante para a exploração regional e é um guia para os mineradores locais.

O texto destaca a potência do aporte teórico da Análise do Discurso para se pensar e praticar o ensino de língua na escola. A partir de três experiências de ensino na educação básica que tomaram por base a abordagem da AD, discutimos o impacto dessa teoria em práticas de leitura, escrita, oralidade e reflexão sobre a língua realizadas em escolas de rede pública, considerando as diferentes condições de produção envolvidas nessas experiências. Refletir sobre a relação entre a AD e o ensino é deslocar os SENTIDOS QUE VÊM SENDO INSTITUCIONALIZADOS para a escola E SEUS SUJEITOS – pela fala pública, pelos documentos oficiais, pelo discurso pedagógico (ORLANDI, 1995).
Fabrication-tolerant Fourier transform spectrometer on silicon with broad bandwidth and high resolution

Published: December 2019

We report an advanced Fourier transform spectrometer (FTS) on silicon with significant improvement compared with our previous demonstration in [Nat. Commun. 9, 665 (2018)2041-1723]. We retrieve a broadband spectrum (7 THz around 193 THz) with 0.11 THz or sub nm resolution, more than 3 times higher than previously demonstrated [Nat. Commun. 9, 665 (2018)2041-1723]. Moreover, it effectively solves the issue of fabrication variation in waveguide width, which is a common issue in silicon photonics. The structure is a balanced Mach–Zehnder interferometer with 10 cm long serpentine waveguides. Quasi-continuous optical path difference between the two arms is induced by changing the effective index of one arm using an integrated heater. The serpentine arms utilize wide multi-mode waveguides at the straight sections to reduce propagation loss and narrow single-mode waveguides at the bending sections to keep the footprint compact and avoid modal crosstalk. The reduction of propagation loss leads to higher spectral efficiency, larger dynamic range, and better signal-to-noise ratio. Also, for the first time to our knowledge, we perform a thorough systematic analysis on how the fabrication variation on the waveguide widths can affect its performance. Additionally, we demonstrate that using wide waveguides efficiently leads to a fabrication-tolerant device. This work could further pave the way towards a mature silicon-based FTS operating with both broad bandwidth (over 60 nm) and high resolution suitable for integration with various mobile platforms.

To obtain a deeper understanding of the impact of photodarkening on laser properties, the evolution of the mode instability threshold and output power in fiber amplifiers was investigated. After pumping for 300 min, the mode instability threshold of the pristine fiber dropped from 770 to 612 W, and the periodic fluctuation of the output power became intense, finally reaching 100 W. To address the detrimental effects originating from photodarkening,

Published: December 2019

ZusammenfassungModerne Medien bestimmen das Berufsleben ständig, überall und tiefgreifend. Auch für die Profession des Coachings gibt es bereits zahlreiche digitalisierte Angebote. Trotz vielfach benannter Vorteile existiert bislang nur wenig Forschung zur Digitalisierung im Coaching. Der vorliegende Artikel illustriert anhand zweier empirischer Untersuchungen Hintergründe des Nutzungsverhaltens digitalisierten Coachings bei externen Coaches und Personalverantwortlichen in deutschen Unternehmen. Unter Verwendung der Theorie des geplanten Verhaltens nach Ajzen (1985, 1991) zeigt sich bei beiden Berufsgruppen, dass die subjektive Norm in Form von Peers, Organisationen sowie der Gesellschaft den größten Einfluss auf die Intention hat, digitale Angebote und Tools im Coaching zu nutzen.
The seaweed resources of Israel in the Eastern Mediterranean Sea

Published: December 2019

AbstractIn spite of the natural harsh marine environments and continuous global change stressors affecting the Levant basin, the Israeli marine flora in the Eastern Mediterranean Sea is quite diverse, with about 300 recognized species. Such high seaweed biodiversity for a small maritime area is remarkable compared to the ca. 1200 species described for the entire Eastern Mediterranean Sea. Since about the year 1890, the Levant basin has been hosting over 115 seaweeds species that migrated from the Indo-Pacific through the Suez Canal. Indeed, approximately 16% of the marine flora is regarded as invasive or exotic to the Israeli shores, in a process that constantly reshapes seaweed populations and their biodiversity. In spite of significant contributions by Israeli scientists to the general biology and technologies for seaweed cultivation worldwide, Israel has little historical and cultural tradition of commercial seaweed cultivation, or use. At present, only two commercial companies are engaged in land-based seaweed cultivation (Ulvasp. andGracilariasp.) with a number of products marketed locally and abroad. Recently, offshore cultivation and biorefinery approaches have been explored, but not yet commercialized.

Published: December 2019

Abstract
The purpose of this study was to investigate the effects of the managerial background of Korean venture capitalists on investment decision strategies and explore how the organizational characteristics of the venture capitals where they work influence the relationship between their managerial background and investment decision strategies. For this purpose, this study used the database of investments and returns of venture funds where Korea Venture Investment Corporation has participated. In additon, this study performed a hierarchical regression analysis based on the research model with Statistical Package for the Social Sciences software, version 24.0. In the results of this study, first, venture capitalists with output or greater investment experience tend to pursue a strategy of investing in the early-stage venture companies or investing in specialized industries. Second, the more investment resources their venture capitals have, the weaker these relationships are.

Published: December 2019

Abstract
To understand the influence of underground mining disturbances on the shallow soil moisture in the Daliuta coal mine, remote sensing monitoring of the temporal and spatial evolution of surface soil moisture and the influence of mining on multi-source, multi-temporal and high spatial resolution remote sensing data were carried out. The scale effect of monitoring the soil moisture at different scales was analyzed using the Scaled Soil Moisture Monitor Index (S-SMMI). In this paper, SPOT 5/6 and Worldview-2 were used as the data source and mainly made up two aspects of the research: 1) based on the three SPOT data sets with the use of S-SMMI from different angles from the Daliuta mine from nearly three years of soil moisture temporal and spatial changes, the results show that the perturbation has a negative effect on the shallow soil moisture in the Daliuta coal mine, and average soil moisture of the mining area is smaller than the non-mining area, but the surface ecological construction has effectively improved the impact of the underground mining disturbance on the surface soil moisture. 2) the scale conversion of Worldview-2 data was carried out based on the resampling method. S-SMMI was used to analyze the scale effect of soil moisture monitoring at different scales. The results show that the difference between the soil moisture is only 0.0016 during the conversion process of 2 m-30 m.
