Expert assessment of practical approaches to optimize the participation of nurses in obtaining informed consent from the patient

INTRODUCTION: Nurses are an important resource to the health system and occupy a significant place in providing effective and quality healthcare. At the same time, obtaining informed consent is an important aspect in the nurses` work. Therefore, the opinion survey and the evaluation of experts on developing practical approaches aim to optimize the participation of nurses in the process of informed consent and have a great scientific and practical significance.AIM: To study the opinion and evaluation of experts on developing practical approaches to optimize the participation of nurses in the process of obtaining informed consent.MATERIALS AND METHODS: We have attached an analysis of the literature and used a documentary and an expert assessment method. An expert assessment of our own developed practical approaches was performed in the period March-September, 2015. It involved 50 experts - chief and senior nurses at the St. Marina University Hospital and used a questionnaire method of interviewing. Its aim was to optimize the participation of nurses in the process of informed consent of the patient.RESULTS: The majority of the experts approved the presented algorithm for obtaining informed consent from the patient and confirmed that the algorithm can be applied in the working process of the nurses. With regard to the presented data sheet for obtaining informed consent for intravenous injection (invasive nursing manipulation) the experts expressed concerns about the possible difficulties in putting it into practice, citing the shortage of nursing staff and time. A significant majority of experts, however, approved the technical sheet and evaluated it as applicable in nursing practice.CONCLUSIONS: The results of the expert assessment lead to the conclusion that the proposed practical approaches are applicable in nursing practice and will help to optimize the process of informed consent, respect the patient‘s right to informed consent, the professional comfort and safety of nurses

Documented dichotomies: the works of Kseniia Khrabrykh as a window towards Otherness

The conceptual dichotomies «masculine-feminine», «Self-Other» structure our reality by leaving out any hybrid phenomenon and, therefore, foment inequalities. In the present essay we analyse the expressive strategies that are used in the documentaries ‘Art of Being Yourself’, ‘The Word’ and ‘Vidimo-Nevidimo’ by Kseniia Khrabrykh, an emerging Russian artist who challenges the dichotomous cognitive schemes, creates a symbolic space of encounter with Otherness and thus promotes empathetic and tolerant attitudes towards the inherent social diversity. We start by approaching the theories on the role of alterity in the construction of identity (including perspectives of postcolonial feminisms and queer studies) with the aim to corroborate the presence of its principles in the three mentioned projects. Next, we focus on defining the conceptual discourse of each work, the format of its visual narrative, its way of evoking the problems treated and the level of its interactivity.Las dicotomías conceptuales masculino-femenino, Yo-Otro estructuran nuestra realidad, fomentando desigualdades y dejando fuera de consideración cualquier fenómeno híbrido. En el presente ensayo analizamos los recursos expresivos que se emplean en los documentales Art of Being Yourself, The Word y Vidimo-Nevidimo de Kseniia Khrabrykh, una artista rusa emergente que pretende desafiar los esquemas cognitivos dicotómicos, crear un espacio simbólico de encuentro con la Otredad y promover así las actitudes empáticas y tolerantes hacia la diversidad inherente a la sociedad actual. Partimos de la aproximación a las diferentes perspectivas teóricas sobre el papel de alteridad en la construcción identitaria (incluyendo los feminismos postcoloniales y los estudios queer) para luego corroborar la presencia sus principios en los tres proyectos mencionados. Seguidamente, nos centramos en definir el discurso conceptual de cada obra, el formato de su narrativa visual, su manera de evocar la problemática tratada y el nivel de la interactividad del trabajo

Simbolismo de agua en el cine: entre el orientalismo poético ruso y el catastrofismo occidental

La representación de agua en las artes visuales tuvo siempre una potente carga simbólica que se nutrió de las tradiciones religiosas y filosóficas de todo el mundo. En función del contexto cultural, este elemento puede hacer referencia a la idea del nacimiento, a la búsqueda espiritual, al subconsciente, a la vía que une el mundo de los vivos y los muertos, etc. La aparición del cine, como un género que da vida a una imagen fija, proporciona al artista la posibilidad de explorar la totalidad de las posibilidades expresivas de las “aguas que corren” convirtiéndolas en un recurso visual recurrente en las obras cinematográficas de todo el mundo. En este artículo ofrecemos un estudio de la presencia acuática como argumento plástico y simbólico en el cine,  centrando nuestra atención sobre todo en el análisis comparativo de las producciones rusas y occidentales. En este sentido,  las primeras ofrecen un simbolismo acuático afine a la tradición oriental y las segundas se decantan por la línea del catastrofismo.   Abstract: The representation of water in the visual arts always had a powerful symbolism that was nurtured by religious and philosophical traditions all over the world. Depending on the cultural context, this element can refer to the idea of ​​birth, to the spiritual quest, the subconscious, the road linking the world of the living and the dead, etc. The emergence of cinema as a genre that gives life to a still picture, gives the artist the opportunity to explore expressive possibilities of the "flowing waters" making a visual recurring resource in cinematographic works all over the world. In this article we provide a study of aquatic presence as symbolic and plastic argument in the film, focusing our attention mainly on the comparative analysis of Russian and Western productions. In this sense, the firsts offer aquatic symbolism tune to the Eastern tradition and the seconds opt for the line of catastrophism.  Palabras clave: Agua; cine; búsqueda espiritual; oriental; occidental; modernidad líquida.

MULTIPLE PATH PARTICLE DOSIMETRY MODEL CONCEPT AND ITS APPLICATION TO DETERMINE RESPIRATORY TRACT HAZARDS IN THE 3D PRINTING

The Multiple Path Particle Dosimetry (MPPD) model is computer software that estimates and visualizes the deposition, clearance, and retention of particles in the respiratory tract systems of humans, rats, and other species. The mathematical model provides a broad spectrum of settings and input options. This research aims to explore the MPPD model concept and determine the deposition fraction (DF), clearance, and retained mass in the human respiratory tract (HRT) based on the geometric mean diameter (GMD) and mass concentration (MC) of particulate matter (PM) emitted during the 3D printing process. We used the real-time air sample data collected during the 8-hour working shift in the 3D printing office. Ultrafine PM deposits mainly in lungs (56%), fine PM mostly deposits in the upper respiratory tract (URT) (41%) and lungs (39%), but coarse PM mostly deposits in the URT (81%). The biggest DF in lower respiratory tract is ultrafine PM (487 μg), the smaller DF is coarse PM (185 μg) and the smallest DF is fine PM (123 μg). The biggest DF in lung for all PM - lower lobes (fine PM - 60%, ultrafine PM, coarse PM - 61%). In a model, where exposure was 5 hours a day, five days a week, during one month, followed by one year of post-exposure period, it was shown that retained mass in the tracheobronchial (TB) region was 1% for ultrafine and coarse PM each, 2% for fine PM, and 55% for all PM in the pulmonary region. The MPPD software is an easily accessible and valuable tool for assessing the impact of PM on the HRT. Particulate matter decreasing in diameter, tend to deposit mostly in the deeper levels of HRT. Tracheobronchial region clearance is more rapid than pulmonary region clearance. Potentially for persons using the 3D-printer regularly the worst health impact could be associated with smaller size of PM, due to tendency deposit mostly in pulmonary region where the clearance rate is slower

Un álbum de recuerdos prestados: La fotografía de Google Street View como vestigio de pertenencia en la experiencia del desplazamiento migratorio

[EN] The present paper offers a reflection on the potential of the platform GOOGLE STREET VIEW as a tool of artistic mediation with the immigrant community. We disigned a workshop that proposes to make a virtual trip to the native land of the participants through this immense 3D photographic archive, creating an album of "borrowed memories" with images of significant landscapes for them. The change of the country of residence not only exposes the person to a different culture, it also deprives him of contact with places that keep memories of the events of his past. The intimate relationship between memory, identity and landscape, gives the images that portray these spaces a powerful emotional load, allowing the immigrant to tell their story from the stages of their past performance. In this sense, the activity we propose gives the opportunity to participants to recall their place of origin through the photographic landscape with the goal of restoring the continuity of their narrative identity, interrupted by the experience of displacement. Likewise, presenting the visual story to the companions allows sharing the mourning of uprooting, building new affective ties with the host environment.[ES] La presente comunicación ofrece una reflexión sobre el potencial de la plataforma GOOGLE STREET VIEW como herramienta de mediación artística dirigida al colectivo inmigrante. Desarrollamos una propuesta de taller que plantea realizar un viaje virtual a la tierra natal de los participantes a través de este inmenso archivo fotográfico 3D, creando un álbum de “recuerdos prestados” con las imágenes de los paisajes significativos para ellos. El cambio del país de residencia no sólo expone a la persona a una cultura diferente, también la priva del contacto con los lugares que guardan recuerdos de los acontecimientos de su pasado. La relación íntima entre la memoria, la identidad y el paisaje, dota a las imágenes que retratan estos espacios de una carga emocional muy potente, permitiendo al inmigrante contar su historia a partir de los escenarios de su actuación pasada. En este sentido, la actividad que proponemos da oportunidad a los participantes de rememorar su lugar de origen a través del paisaje fotográfico, restableciendo así la continuidad de su narrativa identitaria, interrumpida por la experiencia del desplazamiento. Asimismo, presentar el relato visual ante los compañeros permite compartir el duelo del desarraigo, construyendo nuevos lazos afectivos con el entorno de acogida.Esta investigación fue financiada por el Ministerio de Economía y Competitividad en el marco de los proyectos I+D con referencias HAR2015-66288-C4-4-P y HAR2015-64106-P.

Improving the supplier evaluation technique in the company's procurement logistics

The article explores the issues of supplier evaluation and selection in the organization's procurement management, which is particularly important in the context of the dynamics of logistics networks under the influence of modern market trends. The selection of suitable suppliers affects the performance of the logistics system and, consequently, the results of the company's activities. As a result of the study the algorithm and the technique were developed which enable to increase the objectivity and comprehensiveness of supplier evaluation through the use of several methods and selection of key criteria that correspond to the goals, objectives, and needs of the organization. The results of testing the technique are presented on the example of the company engaged in the production of warehouse equipment. To ensure the required level of flexibility, achieve goals and improve company's performance, it is recommended to evaluate suppliers using the proposed technique cyclically, considering changing factors of the external and internal environment

Inhibitory effect of lignin on the hydrolysis of xylan by thermophilic and thermolabile GH11 xylanases

BACKGROUND: Enzymatic hydrolysis of lignocellulosic biomass into platform sugars can be enhanced by the addition of accessory enzymes, such as xylanases. Lignin from steam pretreated biomasses is known to inhibit enzymes by non-productively binding enzymes and limiting access to cellulose. The effect of enzymatically isolated lignin on the hydrolysis of xylan by four glycoside hydrolase (GH) family 11 xylanases was studied. Two xylanases from the mesophilic Trichoderma reesei, TrXyn1, TrXyn2, and two forms of a thermostable metagenomic xylanase Xyl40 were compared. RESULTS: Lignin isolated from steam pretreated spruce decreased the hydrolysis yields of xylan for all the xylanases at 40 and 50 °C. At elevated hydrolysis temperature of 50 °C, the least thermostable xylanase TrXyn1 was most inhibited by lignin and the most thermostable xylanase, the catalytic domain (CD) of Xyl40, was least inhibited by lignin. Enzyme activity and binding to lignin were studied after incubation of the xylanases with lignin for up to 24 h at 40 °C. All the studied xylanases bound to lignin, but the thermostable xylanases retained 22–39% of activity on the lignin surface for 24 h, whereas the mesophilic T. reesei xylanases become inactive. Removing of N-glycans from the catalytic domain of Xyl40 increased lignin inhibition in hydrolysis of xylan when compared to the glycosylated form. By comparing the 3D structures of these xylanases, features contributing to the increased thermal stability of Xyl40 were identified. CONCLUSIONS: High thermal stability of xylanases Xyl40 and Xyl40-CD enabled the enzymes to remain partially active on the lignin surface. N-glycosylation of the catalytic domain of Xyl40 increased the lignin tolerance of the enzyme. Thermostability of Xyl40 was most likely contributed by a disulphide bond and salt bridge in the N-terminal and α-helix regions.
