Abstract. We conduct sensitivity experiments using a general circulation model that
has an explicit water source tagging capability forced by prescribed
composites of pre-industrial sea-ice concentrations (SICs) and corresponding
sea surface temperatures (SSTs) to understand the impact of sea-ice anomalies on regional evaporation, moisture transport and source–receptor
relationships for Antarctic precipitation in the absence of anthropogenic
forcing. Surface sensible heat fluxes, evaporation and column-integrated
water vapor are larger over Southern Ocean (SO) areas with lower SICs. Changes in
Antarctic precipitation and its source attribution with SICs have a strong
spatial variability. Among the tagged source regions, the Southern Ocean
(south of 50∘ S) contributes the most (40 %) to the Antarctic
total precipitation, followed by more northerly ocean basins, most notably
the South Pacific Ocean (27%), southern Indian Ocean (16 %) and South
Atlantic Ocean (11 %). Comparing two experiments prescribed with high and
low pre-industrial SICs, respectively, the annual mean Antarctic
precipitation is about 150 Gt yr−1 (or 6 %) more in the lower SIC
case than in the higher SIC case. This difference is larger than the
model-simulated interannual variability in Antarctic precipitation (99 Gt yr−1). The contrast in contribution from the Southern Ocean, 102 Gt yr−1, is even more significant compared to the interannual
variability of 35 Gt yr−1 in Antarctic precipitation that originates
from the Southern Ocean. The horizontal transport pathways from individual
vapor source regions to Antarctica are largely determined by large-scale
atmospheric circulation patterns. Vapor from lower-latitude source regions
takes elevated pathways to Antarctica. In contrast, vapor from the Southern
Ocean moves southward within the lower troposphere to the Antarctic
continent along moist isentropes that are largely shaped by local ambient
conditions and coastal topography. This study also highlights the importance of atmospheric dynamics in affecting the thermodynamic impact of sea-ice anomalies associated with natural variability on Antarctic precipitation. Our analyses of the seasonal contrast in changes of basin-scale evaporation, moisture flux and precipitation suggest that the impact of SIC anomalies on regional Antarctic precipitation depends on dynamic changes that arise from SIC–SST
perturbations along with internal variability. The latter appears to have a more significant effect on the moisture transport in austral winter than in summer.
Complex Communication and Decolonial Struggles: The Forging of Deep Coalitions through Emotional Echoing and Resistant Imaginations
Authors: Medina José
Published: February 2020

This article elucidates and expands on María Lugones's account of complex communication across liminal sites as the basis for deep coalitions among oppressed groups. The analysis underscores the crucial role that emotions and resistant imaginations play in complex communication and world-traveling across liminal sites. In particular, it focuses on the role of emotional echoing and epistemic activism in complex forms of communication among oppressed subjects. It elucidates Gloria Anzaldúa's storytelling and Doris Salcedo's visual art as exemplary forms of epistemic activism that issue coalitional gestures and critical provocations that can wake people up from their epistemic slumbers and instigate forms of complex communication that can create new possibilities for coalitional politics.

Atualmente, os serviços ambientais relativos aos sistemas agroflorestais (SAFs) estão fundamentados em aspectos qualitativos. Entretanto, para que ocorra a consolidação do pagamentos por tais serviços, os diversos fatores que condicionam os SAFs necessitam ser caracterizados. Este estudo teve comoobjetivos analisar se o estoque de biomassa individual de cafeeiros é afetado porSAFs caracterizados por manejo e arranjos distintos dos cafeeiros arábica e das grevíleas, além de verificar se haveria possibilidade de ajuste de equações alométricas para estimar a biomassa seca dos cafeeiros.O experimento foi conduzido em sistemas de cultivo de café (Coffea arabica L.) sob manejo orgânico e convencional arborizado por grevíleas (Grevillea robusta A. Cunn.), localizados nas regiões do Planalto da Conquista e Chapada Diamantina, Bahia. A partir da determinação da biomassa pelo método destrutivo da simples separação, foram estabelecidas equações de estimativa do estoque de biomassa individual dos cafeeiros. Concluiu-se que o sistema de manejo orgânico e convencional são fatores de menor impacto para o acúmulo de biomassa e carbono em relação à fatores como a densidade de cafeeiros e o arranjo das grevíleas. O menor adensamento de cafeeiros é fator que determina a superioridade dos estoques de biomassa individual.A densidade de cafeeiros e arranjo das grevíleas são fatores que determinam modelos alométricos diferenciados para a estimativa de biomassa dos cafeeiros.

Learning a foreign language by cochlear implant users
Authors: Domagała-Zyśk Ewa , Kłos-Dacka Agnieszka
Published: February 2020

Learning a foreign language is a special challenge for students with hearing impairments as it requires not only developing necessary strategies to learn all language skills in another language, but also overcoming specific perceptual and performance difficulties. The methodology of foreign language teaching to students with hearing impairments describes this process with reference to deaf and hard-of-hearing students of various ages who have various degrees of hearing impairment and who use various communication techniques. However, experiences relating to foreign language learning by people with cochlear implants have not been studied so far. These are students with unique characteristics whose hearing impairments are usually severe or profound and, at the same time, whose functioning is similar to the functioning of hard-of-hearing people thanks to their cochlear implants. It is assumed that their full inclusion in education in mainstream schools and social integration are possible.The article presents the issue of teaching the English language as a foreign language to students with hearing impairments who use cochlear implants (three case studies), especially in the context of the level of independent learning, beliefs concerning foreign language learning, foreign language classroom anxiety or lack of anxiety, and the scope of learning to read, write, speak and listen in a foreign language. In the study, a questionnaire designed by the authors was used as well as the scale FLCAS (Horwitz, Horwitz, Cope, 1986), autonomous scale (Macaskill, Taylor, 2010) and subscale BALLI (Horowitz, 1999).

Authors: Makhmetova Aigerim
Published: February 2020

The article reviews the use of computer technologies at different stages of the lesson and its combination with other techniques and methods of educational activity, as well as observations of practical activity of teachers in special (remedial) schools. The article also evaluates the potential of geography as an academic subject in a special (remedial) school. A lesson of geography in a special school meaningfully integrates the knowledge of nature, society and humans, through which systematization and expansion of understanding objects and phenomena of the surrounding environment is exercised in the students. Geography as a subject of natural science curriculum offers significant opportunities for the development of elementary knowledge on objects and phenomena of animate and inanimate nature, the relationship and interdependence of humans and nature in students with hearing impairment; enriching personal experience of children as a result of systematic observations; the development of required practical skills in the students.The researchers note the significant role of geography lessons in remediating mental and psychological deficiencies in students from special (remedial) institutions. Geography as a subject in a special (remedial) school has an exceptional importance for the overall development of the students.The use of computer technologies in teaching geography to children with hearing impairment is difficult due to the lack of specially designed electronic aids, particularly taking into account the age and mental development of children in this category and guidelines for working with modern TME.The researchers emphasize the significance of visualization in the process of teaching geography to students with hearing impairment as well as note the need for a reasonable combination of verbal, visual and practical methods.This article presents the results of ascertaining experiment and the results of a survey among teachers. Observations of the educational process and surveying the teachers of special (remedial) schools at the stage of the ascertaining experiment revealed the basic forms, tools, techniques and methods of teaching geography to students with hearing impairment.
The level of basic hope, the sense of coherence and life satisfaction in mothers of an adolescent only child with moderate intellectual disability
Authors: Kimszal Marta , Rola Jarosław
Published: February 2020

Analysis of Polish statistical, demographic and sociological data confirms the growing need for research on only children and their families. Over the last few years, however, with the growth in the number of only children, researchers have been showing little interest in the functioning of children, adolescents and adults with intellectual disabilities who have no siblings, and their families' members.The theoretical part of the article presents the functioning and problems of parents of adolescent children with intellectual disabilities. The specific situation of mothers is taken into consideration. The empirical part presents the findings of a study on the level of basic hope, the sense of coherence and life satisfaction in mothers of an adolescent only child with moderate intellectual disability.Three assessment tools were used in the study: the Basic Hope Inventory - a revised version (BHI-R) – by J. Trzebiński and M. Zięba, the Sense of Coherence Scale (SOC-29) by A. Antonovsky, and the Satisfaction with Individual Life Domains Scale by J. Czapiński. The study covered two 36-person groups of mothers with one child and mothers with more than one child aged 15-19 with moderate intellectual disabilities.The findings showed that there were no significant differences between the mothers with one child and the mothers with more than one child in the level of basic hope, the sense of coherence and its components, and life satisfaction. However, the mothers with one child had higher scores on all variables studied. The mothers with one child differed from the mothers with more than one child in a statistically significantly higher level of satisfaction with their education. Mothers of adolescents with multiple disabilities had significantly lower scores for the level of basic hope and significantly higher scores for the level of work satisfaction.

Authors: Ćwirynkało Katarzyna , Żyta Agnieszka
Published: February 2020

Węgierski system oświaty charakteryzuje się najbardziej atypowym rozwojem w całej Europie (Ugrai, 2016). Przez wiele lat panował w tym kraju segregacyjny model edukacji dzieci i młodzieży z niepełnosprawnościami. Zmiany społeczno-polityczne, jakie nastąpiły po upadku komunizmu, czyli na przełomie lat 80. i 90. XX w., wiązały się z pojawieniem się nowych trendów edukacyjnych i rehabilitacyjnych w podejściu do tej grupy uczniów. Artykuł jest pokłosiem wizyty studyjnej autorek na Uniwersytecie Nyugat-Magyarországi Egyetem (University of West Hungary) w Sopronie. Możliwość zwiedzenia placówek dla dzieci bez i ze specjalnymi potrzebami edukacyjnymi (SPE) okazała się inspiracją do dalszych poszukiwań badawczych w celu zgłębienia problematyki kształcenia dzieci ze SPE na Węgrzech.
W pierwszej części artykułu szczegółowej analizie poddano takie zagadnienia, jak: system kształcenia (obowiązek szkolny, etapy edukacyjne, rodzaje szkół), historia kształcenia specjalnego na Węgrzech (począwszy od powstania pierwszych szkół specjalnych, do analizy ważniejszych regulacji prawnych po okresie transformacji politycznej wraz z opisem procesu diagnozy, orzecznictwa i selekcji uczniów do kształcenia specjalnego), wdrażanie idei inkluzji (proponowane rozwiązania i trudności). Część drugą poświęcono refleksjom z wizyty studyjnej, umieszczając ją w trzech odsłonach obrazujących zwiedzane placówki: przedszkola, szkołę specjalną dla osób z niepełnosprawnością intelektualną, placówkę specjalną dla uczniów z uszkodzeniem słuchu, zaburzeniami mowy oraz problemami emocjonalnymi i behawioralnymi.

W pierwszej części artykułu zamieszczono przegląd międzynarodowych badań dotyczących dogoterapii oraz roli psów w procesie rehabilitacji społecznej człowieka. Odwołano się do wyników badań zamieszczonych w prestiżowych zagranicznych czasopismach pokazujących zasadność wykorzystywania psów w terapii dzieci, młodzieży i dorosłych z różnymi chorobami i niepełnosprawnościami. W części badawczej artykułu zaprezentowano dogoterapię jako metodę wspomagającą terapię dzieci z niepełnosprawnością objętych wczesnym wspomaganiem rozwoju. Zastosowano metodę indywidualnych przypadków, techniką wykorzystaną w badaniach była obserwacja uczestnicząca, natomiast narzędziem – arkusz obserwacji oparty na wcześniejszym monitoringu dzieci biorących udział w badaniach. Na podstawie czterech studiów przypadku przeanalizowano zachowanie dzieci podczas terapii grupowej z udziałem psa w czasie 10 spotkań. Przebadano dzieci pod kątem koncentracji, zainteresowania i samopoczucia podczas dogoterapii. Dla każdego dziecka zostały opracowane wskazówki co do dalszej pracy terapeutycznej. Przedstawiono efekty, które udało się zrealizować podczas dogoterapii oraz cele, których nie udało się osiągnąć. W podsumowaniu starano się udowodnić, że dogoterapia może być metodą wspomagającą tradycyjne formy terapii, podkreślono również, że nie jest to metoda uniwersalna i nie wszyscy mogą z niej korzystać.

Task-related educational sensitivity in students with hearing impairments
Task-related educational sensitivity forms the structural basis of the educational sensitivity model. It is a category that covers detailed information on the child's psychophysical development. It includes various tasks that the child performs during the educational process. The task performance level shows the child's educational sensitivity in different areas. Task-related educational sensitivity includes 35 areas of child functioning and is based on observable activities. Their level shows the student's resources, skills, abilities, knowledge and experience.
The study covered 74 children with severe and profound hearing impairments starting elementary school. It was conducted in integrated and special schools in central Poland in the first semester. It aimed to determine the level of task-related educational sensitivity in students with hearing impairments starting elementary school. Thanks to the study, it is possible to know which areas are developed to the largest and smallest extent, which makes it possible to appropriately orient rehabilitation and therapeutic interventions for students with hearing impairments.
Włączenie dzieci ze specjalnymi potrzebami edukacyjnymi w proces edukacji ogólnodostępnej

Published: February 2020

The problem of inclusive education is complex, debatable, but the main thing is that it is really a social issue because it affects the interests of a large number of people. The international community relates inclusive education to the category of legal issues as it calls upon the human right to quality education throughout life. Inclusive education is the state's policy that aims to remove barriers and enable all children to take an active part in education. Inclusive education is just beginning to develop in Kazakhstan. While school is not ready for serious reforms, it can and should take steps forward. Methodological provision for the inclusive educational space is still at the stage of primary development and testing, which considerably complicates the process of introducing practical solutions as methodological support requires a solid empirical base. Further improvement of the system of inclusive education for children with special educational needs requires, first of all, deep scientific understanding and modeling; also, all possible positive and negative consequences should be forecast.
Adapting English as a Foreign Language classes to the needs of students with hearing impairments in early elementary education
Authors: Domagała-Zyśk Ewa
Published: February 2020

Increasingly, deaf and hard-of-hearing students are attending mainstream and integrated schools. It is necessary to provide a number of adaptations, sometimes modifications, of the teacher’s instructional methods and forms for their education to be effective. The purpose of this article is to discuss the issue of adapting English as a Foreign Language classes in early elementary education to the needs of students with hearing impairments. Effective education in this area requires syllabuses, textbooks, and teaching resources that are developed in accordance with the principles of universal design for learning and then necessary adaptations and modifications that are planned on an individual basis following children’s needs and abilities. The author suggests the principles of universal design for learning according to which foreign language instruction for students with hearing impairments should be planned. Due to the internal diversity of this group of students, not only methodological procedures should be individualized but also instructional forms and methods used during English classes as well as the methods of presenting instructional materials by the teacher or other students. In order to optimize the reception and transmission of content, appropriate external conditions that are adapted to individual students’ perceptual and performance abilities need to be provided. Also, the diversity of ways in which students with hearing impairments present their knowledge and thus actively participate in classes is pointed out. Suggesting different adaptations, the author emphasizes the need to take care that instructional materials maintain their full substantive value.
Emotional intelligence structure and level in deaf adolescents
Authors: Opasińska Kaja , Rola Jarosław
Published: February 2020

Emotional intelligence enables people to recognize their own emotions and those of others and to use them in everyday life as valuable information that determines success in social interactions. Inaccurate recognition of emotions or inability to control them can have a significant impact on interpersonal relationships and the ability to cope with difficult life situations. Hearing impairments result in various consequences - both in emotional and social functioning.
The article presents the findings of a research study on emotional intelligence and recognition of facial expressions in deaf adolescents. The data were collected with the use of two tools: the self-report INTE Questionnaire and the Emotional Intelligence Scale - Faces (SIE-T). Study participants were 80 secondary school students, including 40 hearing adolescents and 40 deaf adolescents using sign language. A quantitative method, Student's t-test for independent samples, was used to analyze the significance of the findings.
The research study showed that the deaf people had lower scores than the hearing people both in the level of emotional intelligence and in the level of individual skills that constitute its structure, such as: recognizing emotions, using emotions to guide thinking and action, and recognizing facial expressions. Furthermore, deaf adolescents from deaf families where sign language was the main communication means achieved higher scores in the ability to recognize facial expressions as compared to deaf adolescents from hearing families.
The study suggests the need for broader emotional education and more intensive support for the development of socioemotional skills in deaf adolescents.
Self-perception and social adaptation in people with mild intellectual disabilities
Authors: Kołodziej Dariusz
Published: February 2020

Self-perception is a particularly important determinant of human existence in a broad sense. A multifaceted self-image, its positive perception and acceptance have a significant impact on individual psychosocial comfort, optimal development, and functioning and quality of life improvement.
This paper specifically stresses the need for people with mild intellectual disabilities to develop social skills in a broad sense that influence quality of life and that are determined by a positively perceived self-image and the social adaptation level.
The partial findings of the author’s research study presented in the paper point to numerous spheres of the participants’ personalities and their adaptation behaviors that constitute an important developmental potential of people with mild intellectual disabilities. The self-perception and social adaptation of people with mild intellectual disabilities is treated as a unique aim of objective scientific inquiry in the article. The issues presented from such a point of view can be considered as valid, justified and aiming to optimize the quality of life of people with intellectual disabilities. The paper includes a theoretical discussion and empirical analyses. The theoretical part details the essence of intellectual disability, social adaptation, and self-perception in people with intellectual disabilities. The empirical part provides the methodology of the author’s research study, the findings, and analysis. As a whole, the paper provides a basis for pragmatic conclusions and recommendations.
Reality in blind people’s drawings. Research procedures and tools
Authors: Niestorowicz Ewa
Published: February 2020

The study presented in this article looks at how the phenomena of reality are constructed in totally blind people’s drawings. Analysis focuses on drawing skills and their development seen based on drawings made by people who have been blind since birth. Raised-line drawings made on a special drawing film for blind people were analyzed. The analysis covered:
1. Blind people’s cognitive abilities – the way they see phenomena.
2. Abilities and ways of presenting phenomena in drawings.
3. Determining stages in the development of drawing skills in blind children as compared to the development of drawing skills in sighted children.
The study was motivated by the desire to answer the following questions: What similarities and differences are there in the process of drawing by people with disabilities and in their drawings? What esthetic features (content, form, uniqueness of presentation, manner of displaying emotions) do blind children’s drawings have? How are the phenomena of reality depicted in blind people’s drawings? What difficulties do blind people encounter in making a drawing on a two-dimensional surface? Does blind children’s artistic development take place in a similar way as sighted children’s artistic development? Are blind children at a similar level of artistic development as their sighted peers?
I proposed a model of artistic creation that takes into consideration the content and form of drawings and the artist’s creativity and emotionalism which was used as a tool in the analysis. All aspects of the analysis refer to the stages of drawing development in sighted children proposed by: Stefan Szuman, Viktor Lowenfeld, W. Lambert Brittain, and Georges-Henri Luquet.
Primary and secondary disability appraisal – Predictive role of sociodemographic and disability-related variables
Authors: Byra Stanisława
Published: February 2020

Disability appraisal is a cognitive category examined mainly in the context of adjustment to living with disability. Its significance is usually determined as part of stress and coping theory applied in disability studies. The article presents the findings of a study on primary and secondary disability appraisal expressed by people with acquired motor impairments. Participants were people with spinal cord injuries and with lower limb amputation. Primary and secondary disability appraisal was analyzed with consideration of sociodemographic and disability-related variables. The findings suggest that these categories of variables make it possible to explain primary disability appraisal better than secondary disability appraisal. Also, it was found that disability-related variables had greater predictive significance than sociodemographic variables in explaining the intensity of both primary and secondary appraisal. The type of disability, its duration, and a sense of control over the consequences of one's motor impairment play a significant role in determining the intensity of both forms of disability appraisal.

Authors: Zdziechowska-Dzierzgwa Karolina
Published: February 2020

The article presents basic autism terminology and the current diagnostic criteria. Then, the author focuses on presenting the findings of research on the limitations and potential of people on the autism spectrum in the area of cognitive functions and mathematical skills. The question about the abilities of people with autism remains an unsettled issue. Are the abilities of people on the autism spectrum mechanically learned skills where purely and simply a mechanical factor dominates, or is it possible to see a creative factor in this type of skills? The author is interested in children with autism learning to count. It is an important element of the development of adults and children with autism, but it has not been fully studied. There has not been enough research conducted in this area. The deliberations presented will possibly allow interested people and future researchers to take up this topic with its various aspects and areas.
Procrastination, perfectionism, and locus-of-control in academic settings
Authors: Pearlman-Avnion Shiri , Harduf Roni
Published: February 2020

The present study examines the relationships between procrastination, perfectionism, and locus-of-control (LOC) in an academic setting. Empirical data are drawn from self-report questionnaires completed by 95 randomly sampled students in institutions of higher education in Israel. We differentiate between subjects displaying adaptive and non-adaptive perfectionism and those who are not perfectionists. Similarly, we differentiate between internal and external LOC. The impact of each variable on procrastination is assessed independently, as is the combined effect of perfectionism and LOC. Findings partially uphold the study hypotheses. A significant positive correlation is found between adaptive perfectionism and internal LOC. The degree of procrastination exhibited by non-adaptive perfectionists is higher than that of non-perfectionists. Subjects displaying adaptive perfectionism and internal LOC have lower degrees of academic procrastination than those with non-adaptive perfectionism and external LOC. Findings are discussed in the context of the complexity of the variables and research limitations.

Does Low-level Laser Therapy Provide Additional Benefits to Exercise in Patients with Shoulder Musculoskeletal Disorders? A Meta-analysis
of Randomised Controlled Trials
Authors: Awotidebe Adedapo W. , Inglis-Jassiem Gakeemah , Young Taryn
Published: February 2020

Background. Low-level laser therapy as an adjunct to exercise is common in clinical practice; however, existing evidence for its recommendation is low. To determine whether low-level laser therapy provides additional benefits to exercise in patients with various shoulder musculoskeletal disorders.
Material and methods. An electronic search was conducted on seven databases, including The Cochrane Library, MEDLINE, and CINAH as well as grey literatures, for randomised controlled trials published in English from 1996 to 2018. Selected studies were independently screened and assessed for quality according to the Cochrane Grade of Recommendations, Assessment, Development and Evaluation.
Results. Eleven studies met the inclusion criteria for this review. Moderate evidence indicates that low-level laser therapy provides additional short-term benefit to exercise in improving overall pain (10cm-VAS) (6 RCTs, GRADE quality moderate) (WMD: 1.75; 95% CI: 1.43 to 2.07). However, low evidence indicates that low-level laser therapy provides no additional benefit to exercise for shoulder function [5 RCTs; SWMD: -0.14; 95% CI: -0.79 to 0.25] and range of motions.
Conclusions. 1. Physiotherapists may consider the use of low-laser therapy as an adjunct to exercise in the short run to improve pain in patients with shoulder musculoskeletal disorders. 2. However, low-laser therapy with exercise in the short-term is no more effective than exercise alone in improving shoulder function and range of motions.

Authors: Kłaczyński Robert
Published: February 2020

The aim of the article is to outline the prospects for the Russian natural gas market in the future and to present the Russian gas sector in comparison with the strategic “players” of the global market. The author examines the issues related to the production, transmission and sale of Russian natural gas. The main problem concerns the possibilities and limitations, that influence the power of the Russian “blue fuel” sector. The article presents briefly the results of the research, which were obtained mainly through the method of case study. The verification of the main hypothesis will be made from the top–down perspective, considering analysis of the actions of state decision-making centres. Less explicit impact, including the interaction of non-public actors (such as economic items), will be skipped, because their more precise consideration would provide to the interesting, but different direction of analysis of the sectoral groups of interest.

Volunteering involvementand agency, communion and ethics
Authors: Grabowski Adam
Published: February 2020

The aim of this paper was to check whether there exists a relationship between volunteering involvement and the level of communion, agency and degree of support for ethical codes. The questions concerned whether persons involved in volunteering (compared to those not involved) are characterized, on the one hand, by a higher intensity of agency and communion, on the other, a higher level of declared support for ethical codes (ethics of autonomy, universal good, dignity and collectivism). In order to find the answer, a study was carried out in which participated 37 people involved in hospice volunteering (including 19 women) and 34 non-volunteers (including 18 women).The results of the study show the existence of an assumed relationship in the case of agency and communion. As for ethical codes, the results did not provide evidence of the relationship between the level of their support and volunteering. The results of the presented study lead to the conclusion that selfless action for the benefit of the other people is associated with a high level of agency and communion, and not only with a high ethical level. Hence the postulate for pedagogical practice to shape and develop a sense of agency and communion in children and youth.

Authors: Mutlu Öztürk H. , Öztürk H.K.
Published: February 2020

Purpose: of this study is to address the issue of maintenance work in the accommodation
sector. The development of the means of transport, the increase in income level and the
increase in comfort level create a desire for people to travel more. In the travels to different
cities, accommodation facilities such as hotels, holiday villages and apartments are used.
Customer satisfaction is very important for the accommodation facilities. In order to ensure
customer satisfaction, the services provided should not be interrupted and all machinery
and equipment must be in working condition. To ensure this, it is very important to carry out
maintenance work on the plants and devices. Therefore, the establishment of a maintenance
management system in accommodation facilities is very important and it is necessary to
carry out maintenance work. In this context, different maintenance methods are applied in
accommodation facilities. In this study, maintenance of accommodation facilities is discussed.
Design/methodology/approach: Within the scope of the study, maintenance and
maintenance management in accommodation facilities are discussed. The maintenance
principles of accommodation facilities are discussed in detail. The places where maintenance
services are conducted in accommodation facilities and maintenance methods are
discussed.
Findings: This study shows that that the implementation of maintenance management
system will increase customer satisfaction. It has been evaluated that maintenance can be
successful not only by maintenance personnel but also with the participation of all plant
employees.
Research limitations/implications: In order to see the importance of maintenance in
accommodation facilities, it will be appropriate to compare the hotels with the maintenance
management system applied and the hotels that are not implemented in terms of
customer satisfaction and maintenance expenses. For the future studies, the maintenance
management system in hotels can be examined in detail.
Practical implications: Expanding the maintenance management practices in
accommodation facilities will increase the capacity utilization rate of the hotels and increase
customer satisfaction.
Originality/value: In the field of maintenance, detailed studies have been carried out in
the manufacturing sector for a long time and have been examined in detail. However, work
in this area is quite limited, especially in accommodation facilities and hotels. In this study,
the subject of accommodation facilities and maintenance of hotels was discussed in detail.
Eco-physiological peculiarities of Stellaria humifusa in West Spitsbergen

Published: February 2020

In the present paper, the results of the research of biometric parameters and functional peculiarities of photosynthetic apparatus of Stellaria humifusa in West Spitsbergen are discussed. The study showed that the largest proportion of the mat is composed of a brown layer of dead leaves covering the assimilative organs (about 70%). Green leaves and shoots accounted for about 20%, whereas generative organs – for about 10% of the mat mass. The values of the maximum photochemical quantum yield of PS II (FV/FM) in all the studied plants were lower than the optimal values (0.83), which suggests that the plants are exposed to stress factors. The low values of chlorophyll and carotenoid content and relatively high values of the light-harvesting complex (70-80%), the sharp decrease in the quantum yield of PS II (FPSII) entailed by a marginal increase in PPFD indicative of a sufficiently high of photochemical activity within the range of low and medium values of light. It also suggests that Stellaria humifusa is well-adapted to the shaded conditions created in the mat. Besides, a considerable decrease the maximum fluorescence yield of a light-adapted leaf (FM´) at increasing PPFD was observed, which suggests that Stellaria humifusa has a well-developed mechanism of energy dissipation via the non-photochemical (NPQ) pathway. The rapid development of NPQ gives reason to assume that, under high light conditions, non-photochemical quenching is likely to serve as the main mechanism for preventing the photodamage of the photosynthetic apparatus. Thus, it was shown that the photosynthetic apparatus of Stellaria humifusa works efficiently under the conditions created in the mat, and the thick layer of dead leaves covering the assimilative organs, on the one hand, protects them from excessive light, and on the other hand, absorbs thermal energy, which raises temperature of the local habitat.
Photoinhibition of primary photosynthetic processes in hydrated Polytrichum commune: Analysis of non-photochemical quenching affecting species resistance
Authors: Maria Giudici Gabriella Nora
Published: February 2020

A moss from the alpine environment of the Jeseníky mountains, Polytrichum commune, was studied under lab-induced light stress to analyse photoinhibition (PI) stress response; three PI doses were used: PAR 1500 µmol m-2 s-1 for 60 min., 1200 µmol m-2 s-1 for 60 min. and 1200 µmol m-2 s-1 for 30 min.; in the last one the added component of slight desiccation stress was added. Chlorophyll fluorescence parameters were plotted as time series, immediately before and after the PI treatments, then every 20 minutes for three hours (recovery period). FV/FM, ΦPSII and NPQ parameters and quenching components were analysed. Decreasing courses and final values of FV/FM and ΦPSII parameters along with increased values of NPQ clearly indicated PI stress response, although not very severe. Quenching parameters analysis showed a dominant role played by xanthophyll pigments along with changes in PS II in the non-photochemical energy quenching. Dehydration contributed additional value to NPQ. All these factors are consistent with the adaptation of the species to harsh conditions of alpine environments.

Histological and Histochemical Studies on the Lingual Tonsil of the Buffalo (Bubalus bubalis)
Authors: Girgiri Ibrahim Alhaji , Kumar Pawan
Published: February 2020

The study was conducted on lingual tonsil of six adult buffaloes (5-6 years of age) of the local mixed breed to explore histomorphological characteristics with functional significance. The mucosal surface of the lingual tonsil lined by stratified squamous keratinized epithelium was comprised of strata basale, spinosum, granulosum and corneum whereas towards the deeper folds the epithelium was stratified squamous non-keratinized. The latter epithelium modified into reticular epithelium especially toward the deeper portion and was characterized by a reduced number of epithelial cells, loss of distinct strata and heavy infiltration of lymphoid cells. The propria submucosa had loose irregular connective tissue along with glandular and lymphoid tissue. The lymphoid tissue was mainly distributed in the form of lymphoid follicles and diffused arrangement. The follicles of varying shapes and size showed darkly stained corona and lightly stained germinal centre were surrounded by parafollicular areas. The parafollicular areas possessed high endothelial venules (HEVs) with large sized endothelial cells having round to oval nuclei with distinctly visible centric or eccentric nucleoli. These HEVs are involved in trafficking of lymphocytes by transendothelial and interendothelial migration. The mucous glandular acini presented strong reactions for glycogen, acidic mucopolysaccharides, weakly sulfated mucosubstances, hyaluronic acid, sialomucins and mucins as demonstrated by different histochemical techniques. The secretions of acini also showed the presence of more than 4% content of cysteine. The presence of modified reticular epithelium and associated lymphoid tissue suggested that the lingual tonsil may be involved in sampling of oral antigens and transporting them to the underlying mucosal lymphoid tissue for processing and initiation of immune responses. The future microbiological studies may exploit the tonsil as a targeted organ for improved delivery of existing mucosal vaccines and development of new strategies for oral vaccines.

Reconfiguring Minimum Dominating Sets in Trees
Authors: Lemańska Magdalena , Żyliński Paweł
Published: February 2020

We provide tight bounds on the diameter of $\gamma$-graphs, which are reconfiguration graphs of the minimum dominating sets of a graph $G$. In particular, we prove that for any tree $T$ of order $n \ge 3$, the diameter of its $\gamma$-graph is at most $n/2$ in the single vertex replacement adjacency model, whereas in the slide adjacency model, it is at most $2(n-1)/3$. Our proof is constructive, leading to a simple linear-time algorithm for determining the optimal sequence of ``moves'' between two minimum dominating sets of a tree.
