Job demands and resources of managing directors of micro- and small enterprises: A qualitative study of the German transport industry
Authors: Winkler Eva
Published: March 2022

BACKGROUND: In many European countries, entrepreneurs have to consider psychosocial factors in the workplace risk assessment. Little is known about psychosocial working conditions in micro- and small companies. Even less is known about the entrepreneur in these settings. OBJECTIVE: The present study was conducted to develop and examine the job demands and resources of small business owners and managers, who serve as important designers of their businesses’ working characteristics. METHODS: N = 29 semi-structured interviews with a unique sample of owners and managers of the transportation sector were analysed via qualitative content analysis. RESULTS: The data suggest the presence of specific demands (time-, management-, and organisational demands) and resources (support and feedback). In particular, the variability and load of the demands indicate that the existing theoretical framework for employees is inadequate for evaluating the working characteristics of micro- and small business managers. CONCLUSION: Occupational health activities in small companies should include the working situation of the entrepreneur/manager.

Published: March 2022

BACKGROUND: A growing body of literature has showed the need to minimize the impact of rotating shiftwork (RS) on health of shift-healthcare workers (HCWs). OBJECTIVE: The aims of the study were: 1) assessing the occupational risk associated with RS program in HCWs employed in 24 hours hospital wards 2) testing the feasibility of the questionnaire used. METHODS: The Rotating Shiftwork Questionnaire (RSQ) was implemented to assess the RS risk (RSR); the analysis was addressed to: 1) Sentinel events (SE) and 2) Risk factors (RF). The RSQ was administered to the specialist nursing coordinators in eighteen hospitals in Italy with the aim to evaluate the RSR index among nurses in 24 hours hospital wards. RESULTS: Eighteen structures participated in the multicenter study, of which 12 (66.7%) were public. Concerning the Rotating Shiftwork Risk index, there are the 78.8% of observations in the intermediate zone, with RSR scores ranging from 14.1 and 16 and in the high score area (RSR > 26) in which there are 4 observations equal to the 21.2% of the total. The multivariate analysis showed that the only significant variable associated with RF score was the macro-area (for Northern regionsbeta = –0.651; p = 0.008). CONCLUSIONS: RSQ has been shown a feasible and applicable tool to analyze the RSR in healthcare sector through the detection of quantitative data involving indicators of the risk. The questionnaire allowed to identify improvement actions targeted at minimizing specific critical issues through strategic interventions focused on organizational environment.

Published: March 2022

BACKGROUND: Hearing problems can have adverse effects on an individual’s job performance, as well as on unemployment or underemployment and increased risk of stress-related sick leave. OBJECTIVE: To investigate hearing impairment among workers and satisfaction with the use of hearing aids. METHODS: Cross-sectional study with workers who are hearing aid users. Subjects underwent pure tone audiometry and answered the Hearing Handicap Inventory for Adults and the Satisfaction with Amplification in Daily Life questionnaires. RESULTS: Participants were 36 workers between 36 and 75 years old, with an average age of 53.47 years, 52.7% male and 47.3% female. There was a mild to moderate hearing handicap perception, with worse results for women in the emotional domain. As hearing loss increased, workers’ frustration increased when talking to coworkers. Everyone was satisfied with the use of their hearing aids. Satisfaction increased with increasing age and decreased with increasing hearing loss. The greater the frustration when talking to co-workers, the lower the overall satisfaction with hearing aid use; the lower the satisfaction with the competence of the professional who assisted in adapting the hearing aid; the lower the satisfaction in environments with background noise and overall worse personal image. The worse the attitudes and emotional responses of workers regarding their hearing impairment, the lower the overall satisfaction with the hearing aid. CONCLUSIONS: Despite the use of hearing aids, workers perceive having a hearing impairment, especially women. As hearing loss and frustration in talking with co-workers increased, satisfaction decreased.

BACKGROUND: Improving the level of knowledge, attitude and practices of workers exposed to heat stress using a suitable tool can be a cheap and effective method. This requires the consideration of personal, environmental and social factors, which, the PRECEDE model is highly applicable for. Thus, the aim of the present study is the development of a tool assessment for measuring the knowledge, attitude and practices of workers in outdoor occupations regarding heat stress exposure using the PRECEDE model. METHODS: In the present study, a tool was designed and constructed using the PRECEDE model by analyzing the relevant literature and expert opinion. The face validity of the tool was determined based on the opinion of ten experts with experience in the field of occupational weather conditions. The content validity of the tool was determined using the Content Validity Ratio (CVR) and the Content Validity Index (CVI). Cronbach’s alpha reliability coefficient was used to determine the reliability of the tool’s internal consistency. SPSS version 23 was used for statistical analysis. RESULTS: A PRECEDE based questionnaire was designed with a total of 55 questions consisting of predisposing factors (28 questions for knowledge and 14 questions for attitude), enabling factors (5 questions), reinforcing factors (3 questions) and preventive behaviors (5 questions). The Content Validity Index (CVI) of all questions was above 0.79. The Content Validity Ratio (CVR) of all questions was above 0.62 (Lawshe method). The Cronbach’s alpha reliability coefficient of all PRECEDE domains were above the 0.7 acceptable value. Based on the results obtained, all 55 questions were approved and thus the content validity and reliability of this tool was deemed acceptable. CONCLUSION: Considering the reliability and validity of this tool, its application is recommended in all health and safety inspections within various industries for measuring the heat stress knowledge, attitude and practices of workers engaged in outdoor occupations and also for presenting suitable solutions or preventive measures.
Ergonomic problems in agricultural farms: Explainable relationship between awkward postures and body discomforts in Iranian leafy vegetable cultivation
Authors: Hayati Abdollah , Marzban Afshin
Published: March 2022

BACKGROUND: Many agricultural activities excessively need human power and are associated with musculoskeletal disorders (MSDs). Leafy vegetable cultivation (LVC) is one of these. OBJECTIVE: The postural workload, body discomfort, and explainable linkage between these among Iranian wintry LVC workers were investigated. METHODS: Postures and body discomfort were evaluated using Ovako working posture analyzing system (OWAS) and a body map, respectively. The explainable body discomforts by working postures for each body region were descriptively discussed using some of the literature. RESULTS: Considering the maximum MSD risk value of 400%, irrigation and manual harvesting had the highest MSD risks with index risks of 313% and 305% respectively. Low back discomfort was the most common body discomfort in LVC which was reported for the operations of moldboard plowing, disking, manure application, chemical broadcasting, spraying, and manual harvesting. LVC operations seemed to rely heavily on the use of low back and shoulders. Bent and/or twist postures were the most common postures for the back. CONCLUSIONS: Almost all the body discomforts were explained by awkward postures shown by postural workload analysis. Therefore, the working posture analysis results may be reliable and utilized in future decisions around ergonomic interventions. Future studies may be conducted to investigate the simple and inexpensive ergonomic interventions to mitigate MSD risks.

Published: March 2022

BACKGROUND: Prolonged use of the smartphone causes neck and shoulder pain. However, no study has yet evaluated the effects of sitting upright, combined with frequent breaks, eye rest and self-stretching on pain and EMG during smartphone use. OBJECTIVES: The purpose of the study was to compare pain and muscle activity between the control group (rest only) and the intervention group (rest combined with correct posture, eye rest and self-stretching) in smartphone use for 41.30 minutes. METHOD: Forty-four healthy females aged 18–25 years old were recruited and randomly divided into two groups. The body pain chart and Visual Analog Scale (VAS) were used to evaluate pain. Electromyography (EMG) was used to measure muscle activity of Cervical Erector Spinae (CES) and Upper Trapezius (UT) muscles. RESULTS: The results showed that overall pain and neck pain in the control group increased significantly after smartphone use for 20 min and continually increased to 41.30 minutes (p < 0.05). Overall pain and neck pain in the intervention group was significantly lesser than control group after smartphone use for 41.30 minutes (p < 0.05). In the control group, EMG of CES at 41.30 minute was significantly higher than that of at 0 min (p < 0.05). There was no significant difference in EMG of UT between the two groups. CONCLUSION: Conclusion smartphone user in the interventional group reported less pain when compared to control group after Smartphone use for 41.30 minutes. Therefore, the user aged 18–25 years should have a rest combined with correct posture, eye rest and self-stretching to prevent neck pain during prolonged smartphone use.
Electromyography analysis: Comparison of maximum voluntary contraction exercises for the latissimus dorsi
Authors: Al-Qaisi Saif , Saba Alif , Alameddine Ibrahim
Published: March 2022

BACKGROUND: A prerequisite for interpreting electromyography (EMG) data is to normalize them to a maximum voluntary contraction (MVC), expressing them as percentage of the MVC. OBJECTIVE: The objective of this study was to compare different recommended MVC exercises for the latissimus dorsi and identify the exercise that elicits the highest EMG amplitude. METHODS: Fifteen male participants were recruited. Five recommended MVC exercises were investigated, including chest-supported shoulder extension, prone shoulder extension, lat-pull down, abducted shoulder flexion, and internal shoulder rotation. RESULTS: Chest-supported shoulder extension reported the highest mean EMG, which was not significantly different from the mean EMG of prone shoulder extension. Both of these exercises led to significantly greater EMG means than the other exercises. Sixty percent of the participants achieved their highest EMG amplitude with chest-supported shoulder extension and 40% with prone shoulder extension. None of the other exercises elicited the highest EMG amplitude in any of the participants. CONCLUSIONS: Both chest-supported shoulder extension and prone shoulder extension proved to be effective MVC exercises, with the former showing more consistency in eliciting the highest EMG amplitude. If the true MVC is desired, the authors recommend performing both exercises and then using the overall highest EMG amplitude for normalization purposes.

Authors:   Belarusian State University, Menkouski V.I. , Dubinka-Hushcha L.A. ,   Copenhagen Business School
Published: March 2022

The article analyses the historical policy of the Russian Federation and its modern memorial culture areas. The study applies the case studies methodology, i.e., «study of individual cases», «analysis of a single case». The object of study is a socio-political situation associated with the 150th anniversary of V.I. Lenin. An analysis examines the transformation of the contradictory Leninist image in the Russian Federation and the attitude of various social and power structures, based on specific sociological surveys. A thorough study of empirical material allowed us to analyze the basic functions of the historical policy of the Russian Federation at the present stage. It became possible to analyze the interaction and mutual influence of the corporation of professional historians and Russian power structures, the behavior of state and public actors in the process of forming and implementing historical politics and memorial culture. The goal and objectives of the elites and other social strata in the implemented historical policy may coincide, partially correlate or contradict, but in the “Lenin case”, the situation was complicated by the absence of a scientifically defined object of this policy. Both the authorities and society expressed their attitude not to the existing V.I. Ulyanov (Lenin), but to those legendary (or mythical) images that were created in different periods with completely different goals.
On the importance of moisture-resistant properties of concrete in the construction of current-limiting reactors of a substation
Authors:   L.N. Gumilyov Eurasian National University, Rakhimov R.V.
Published: March 2022

Switchgears are an integral part of the energy industry of the Republic of Kazakhstan, which include substations, electrical installations, power transmission lines and other facilities. Currently, they are undergoing physical and moral wear and tear. The growth of production capacities of industry and the population emphasizes the need for intensive development of the energy complex using the technologies of the XXI century, while maintaining a technological balance between traditional energy and renewable energy sources [4]. The concept of development of the fuel and energy complex of the Republic of Kazakhstan until 2030 fully reflects these tasks and development approaches. In addition, the construction and reconstruction of distribution networks are due to the growth of a total load of consumers, which, even now, continues to increase rapidly. Concrete used in construction is an integral part of all types of construction and installation work. Thus, the concrete mixture used in the construction of energy facilities must have special properties and moisture-resistant characteristics, allowing you to solve specific energy problems, which include: reliability, durability, low electrical conductivity and other characteristics of concrete structures. High indicators of the above requirements are imposed in the places of installation of current-limiting reactors at electrical substations.
Development and testing of the concrete maturity sensor housing
Authors:   University North, Aniskin A.
Published: March 2022

The two types of custom housings for the maturity sensor made of twocomponent plastic were proposed and subjected to durability testing in this study. The first rectangular housing was made of two parts connected by 6 screws and waterproofed with rubber. The second housing was made keg-shaped with a cylindrical keg and screw-on cap. The housings were tested for water resistance, integrity when dropped, and load resistance on three sides using an electromechanical press-machine. At compression tests, both housings demonstrated fairly acceptable resistances, ranging from 0.6 to 2.11 kPa. If referring to the weight applied, it may be supposed that the housings may bear from 65.3 to 165.3 kg depending on the sides, on which the loads are applied. The integrity tests did not cause notable damage on both types of housings, while the water-resistance test revealed the weakness of rectangular housing that failed the test at 3 days of submerging. Comparatively, the cylindrical housing turned out to be more reliable, since its average resistance deviation on all sides appeared to be twice less than those in rectangular one. Moreover, the keg-shaped housing turned out to be waterproof, less material, and labor-intensive.

Published: February 2022

Introduction: Sexual dysfunction is considered a common sexual problem affecting different aspects of life, and it seems to be rooted in individual's personality. Aim: This paper aims to compare prevalence of sexual dysfunctions between those with narcissistic personality disorder (NPD) and healthy persons. Method: This is a causal – comparative research. To do so, 700 males and females from Tehran City were screened in 2021, among them 120 persons were diagnosed with NPD and 41 persons were selected through convenience sampling as individuals with disorder. Data of 40 healthy persons were analyzed for comparative purposes. Millon Clinical Multiaxial Inventory (MCMI3), Female Sexual Functions Index (FSFI) and International Index of Erectile Function (ILEF) were used. Data were analyzed by comparing two independent groups in SPSS, Version 26. Results: In females, there were no significant differences in sexual function (t=1.011, P=0.320), moisture (t=0.537, P=0.595), orgasm (t=-0.539, P=0.594), sexual pleasure (t=0.164, P=0.871) and pain (t=0.999, P=0.327) between narcissists and healthy persons. Difference in sexuality (t=2.289, P<0.05) and arousal (t=2.107, P<0.05) in healthy persons was more significant than narcissists. Moreover, in males, the difference in sexual function (t=7.545, P<0.001), sexuality (t=12.871, P<0.001) and erection (t=4.832, P<0.001) in healthy persons was more significant than narcissists, and orgasm (t=-3.426, P<0.01) in narcissists was less than in healthy persons. However, there was no significant difference between sexual pleasure in both groups (t=-0.866, P=0.393). Conclusion: The results show that prevalence of sexual dysfunctions in narcissists is more than healthy persons. Therefore, it is recommended that counselors and psychologists consider personality traits in diagnosis and treatment of sexual disorders.

This study explores the regional pattern of association between health risk exposure and resilience outcome in South Asian countries with the outbreak of the Covid-19 pandemic. This exercise unveils the elements of resilience that contribute to getting prepared in confronting COVID-19 risk in South Asia, using secondary information and knowledge from the Governments, WHO, UNDP Human Development Index (HDI), European Commission’s COVID-19 Risk Index and the World Bank’s Air Connectivity Index. Methodology and Scope of the paper differ from previous contributions from a holistic policy point of view, since human development, geo-demographic vulnerability, government effectiveness and socio-economic outcome variables are considered in context to the public health condition and epidemic risk at the national level. Based on statistical evidence, South Asian countries fall into three categories (i) high resilient with low pandemic impact (Maldives, Bhutan and Sri Lanka), (ii) Medium resilient having a high impact (India and Bangladesh) and (iii) Low resilient but high impact (Pakistan, Afghanistan and Nepal). Beyond resilience, this study also flags geo-demographic issues such as population density, geographical isolation either being an island or landlocked mountainous countries and air travel connectivity as influencing or barrier factors in the spreading of epidemic disease. This paper serves the purpose of designing risk-informed effective policy responses to constrain negative effects of future pandemics and similar infectious diseases and sensitize countries to get prepared for “build back better” as well.

Published: February 2022

This study investigates the extent to which external debt and public investment contribute to economic growth in Cameroon-emphasizing how public investment modulates the effect of external debt on economic growth. Time series data spanning the period 1980-2021 obtained from the World Bank’s world development indicators were used, together with the Dynamic Ordinary Least Squares (OLS) approach to ascertain the nature of the long-run relationship between external debt, public investment, and economic growth in Cameroon. Consistent with the debt-overhang and crowding-out literature, the study reveals a negative significant influence of external debt on economic growth in Cameroon. Results also reveal that there is a positive and significant direct effect of public investment on economic growth in the long run. Further results indicate that public investment and external debt positively and significantly affect engender economic growth in Cameroon. This is evidence that public investment modulates the effect of external debt on economic growth in Cameroon. These findings suggest the need for the government of Cameroon to create an enabling environment for private sector investment while accompanying external debt resources with domestic revenue mobilization by broadening the tax base to include taxes on landed property.

Published: March 2022

Esta investigación plantea nuevas preguntas sobre la autonomía personal, vinculadas con las tecnologías de la información y la comunicación y los universitarios, relevo generacional educado de un país. Cómo los jóvenes usan estas tecnologías y si estos usos ayudan al florecimiento de su autonomía personal, son dos de las interrogantes principales que guiaron este proyecto. Desde el enfoque del desarrollo humano y la propuesta teórica de las tecnologías en la práctica, se analizaron los datos de una encuesta diacrónica (2015-2020), aplicada a 621 estudiantes de dos universidades públicas de México, del noreste y el centro-occidente, respectivamente. De los hallazgos, se desprende una tipología según los tres perfiles de estudiantes identificados, donde se considera la adopción de estas tecnologías, al mismo tiempo que se visibiliza la mediación que tienen los padres en su desarrollo de capacidades educativas. Asimismo, se proponen tres variables relativas a la categoría autonomía personal, según las potencialidades y contextos de estos jóvenes. Se concluye que si bien el uso de las TIC es fuertemente promulgado por las instituciones educativas – condicionado por las estructuras y herramientas digitales que posean–, este no contribuye a un florecimiento relevante de la autonomía personal de los universitarios.

Authors: Ahmed Khaleel Almas , Hussein Al-Khalidy Joanna
Published: March 2022

There are many traditional classification algorithms used to classify multispectral images, especially those used in remote sensing. But the challenges of using these algorithms for multispectral image classification are that they are slow to implement and have poor classification accuracy. With the development of technologies that mimic nature, many researchers have resorted to using intelligent algorithms instead of traditional algorithms because of their great importance, especially when dealing with large amounts of data. The bat algorithm (BA) is one of the most important of these algorithms. This study aims to verify the possibility of using the BA to classify the multispectral images captured by the Landsat-5 TM satellite image of the study area. The study area represents the Mosul area located in the Nineveh Governorate in northwestern Iraq. The purpose is not only to study the ability of the BA to classify multispectral images but also to obtain a land cover map of this region. The BA showed efficiency in the classification results compared to Maximum Likelihood (ML), where the overall accuracy of classification when using the BA reached (82.136%), while MLreached (79.64%)

USEFULNESS OF OUT-OF-SCHOOL LEARNING IN SCIENCE EDUCATION
Authors: Janiuk Ryszard M.
Published: February 2022

Out-of-school learning has been playing an increasingly important role in science education. It can be implemented in various ways and encompasses learning activities that take place outside normal lessons reserved for compulsory education. This form of education is typically not coordinated by the school itself and young people take part in it voluntarily. It resembles “outdoor education”, which is, however, more closely linked with meeting aims stemming from formal education. Since the learning activities used in both forms of education are similar, very often solutions and experiences in one form are transferred to the other.
Educators from many countries have shown considerable interest in out-of-school learning for many years. It is recommended in official documents concerning formal education and by organisations dealing with science education. Already in 1996, the National Science Education Standards, which are a set of guidelines for science education in primary and secondary schools in the United States, emphasised the importance of this method of expanding and supplementing students’ knowledge. Similarly, the materials for teachers accessible on the website of the Association for Science Education in the UK contain several useful tips concerning the use of out-of-school learning in science education.

The aim of this study was to investigate the effects of organic chemistry anxiety on sophomore undergraduate students in relation to chemistry attitude and organic chemistry achievement. The participants were 228 sophomore undergraduate students, enrolled in organic chemistry courses. Anxiety and attitude were measured using O-CAS and CAS, respectively. O-CA was measured by determining a point total for each student, using the results of exams and quizzes from organic chemistry courses. The results of an ANOVA showed a significant difference in the means for O-CA and chemistry attitudes scores between the low, moderate, and high anxiety groups. The findings also revealed a moderate, significant negative correlation between organic chemistry anxiety and achievement, and a small, significant negative correlation between organic chemistry anxiety and chemistry attitudes. In addition, there was a small, significant positive correlation between chemistry attitudes and organic chemistry achievement. Key words: achievement, chemistry attitude, organic chemistry anxiety, undergraduate students.
THE EFFECT OF PEER INTERACTIONS ON QUANTUM PHYSICS: A STUDY FROM CHINA
Authors: Shi Wei-Zhao
Published: February 2022

Many studies in the field of physics have demonstrated that courses which include a component of interaction among peers achieve significantly higher gains in conceptual understanding. However, few of those studies have closely examined the role play in quantum physics. Unlike classical physics, the area of quantum physics has little relation to experiences of students in everyday life. This makes quantum physics very difficult to teach. In this study, Ireson’s 29 questions regarding the quantum physics conceptual understandings were developed and validated, then used in the pre- and post-test. It was found that a significant difference in the mean number of correct responses between the experiment class and the control class, through their participation in peer conversations, experiment class students achieved a stronger overall understanding of quantum physics concepts. The result is the same as the previous research in classical physics.

Published: February 2022

The study focuses on how best to foster the science process skills and improving achievement of secondary schools students in Riau Indonesia. This research used a quasi-experiment method which involved two experimental groups and one control group. The first experimental group used an environment learning module based on Information Communication Technology (ICT), whilst the second experimental group used the environmental module without ICT. The third group went through the teaching and learning process using conventional methods. The instruments used were the Science Process Skills test and students’ achievement test. Analysis of the findings was done descriptively followed by subsequent inferential analysis using ANOVA and MANOVA tests. It was found that there exist significant differences in science process skills and achievement between the two experimental groups and the conventional group. Based on the findings, it is suggested that science teachers need to be adroit in varying their teaching approaches as well as orientating themselves in using ICT in their teaching.

THE EFFECTS OF INQUIRY SUPPORTED BY ARGUMENT MAPS ON SCIENCE PROCESS SKILLS AND EPISTEMOLOGICAL VIEWS OF PROSPECTIVE SCIENCE TEACHERS
Authors: Ünal Çoban Gül
Published: February 2022

Situating arguments as a central element in the design of inquiry learning environments is important for engaging learners in the coordination of conceptual and epistemological goals. The purpose of this study was to find out the effects of inquiry based laboratory activities which are supported by argument maps on the prospective science teachers’ science process skills and epistemological views. A quasi experimental research was conducted with sixty 3rd grade prospective science teachers of a faculty of education in Turkey for over 3 months. The results displayed that although the inquiry supported by argument maps had significantly affected the science process skills of prospective science teachers’, it did not affect their epistemological views. It is thought that it may take some time and special efforts to see the effects of inquiry supported by argument maps on the epistemological views of prospective science teachers.
Key words: argument mapping, inquiry, prospective science teachers.
LEARNING APPROACHES TO APPLYING ROBOTICS IN SCIENCE EDUCATION
Authors: Altin Heilo , Pedaste Margus
Published: February 2022

The methodology and ideas behind educational robotics arise from the 1960s, when the first hardware platforms together with computers were used in research studies in schools. Since the 1990s, the market for educational robotics has grown, and there are many solutions available to use in schools. Despite a wide variety of platform approaches for using robots in education, they are still based on ideas that are decades old. This study evaluates different approaches used nowadays to teach with robots. Problem-based, constructionist, and competition-based learning are identified as the most common uses of robots under observation. Each approach is analysed qualitatively based on the published literature. Each has positive and negative properties; though none have been studied thoroughly using quantitative methods. Results indicate that all these approaches are used in schools with robots interdisciplinary. The current reasons for using robots are based mostly on teachers’ and students’ impressions. However, robotics can be seen as a “tool” to create many approaches to science education, such as inquiry learning and problem solving. Key words: constructionism, constructivism, educational robotics, inquiry learning, LEGO Mindstorms, problem solving.

Introducción: Entre las anemias hemolíticas de carácter hereditario, la esferocitosis hereditaria (HS) es aquella que se presenta con mayor frecuencia. Los patrones de herencia autosómico dominante (AD) y autosómico recesivo (AR) representan el 75% y el 25% de todos los casos de HS, respectivamente. La prevalencia de la HS varía entre las diferentes regiones raciales y étnicas, y afecta aproximadamente a 1 de cada 2000 personas en el norte de Europa, América del Norte y Japón, pero es menos común en los afroamericanos y en el sudeste asiático. El síndrome colestásico es una de las complicaciones más comunes y suele presentarse en pacientes entre 10 y 30 años, aunque los pacientes más jóvenes también pueden presentarlo y la colecistectomía es un tratamiento radical seguro y eficaz para esta patología. Objetivo: Describir la evolución clínica y el manejo quirúrgico de la paciente con esferocitosis que desarrolla un síndrome colestásico como una de las complicaciones más frecuentes de esta patología. Materiales y métodos: El sustento teórico de este caso clínico, correspondiente a la información más actualizada hasta 5 años atrás, se obtuvo a través de la búsqueda de literatura y el acceso a artículos científicos, libros, revistas y otros documentos físicos y virtuales a través de buscadores profesionales en el campo de la salud. Conclusiones: La evolución de las complicaciones de la esferocitosis hereditaria en especial del síndrome colestásico conllevo a varios días de estancia hospitalaria, pero en la mayoría de las ocasiones se suelen resolver favorablemente en este caso por medio de la colecistectomía laparoscópica se obtuvo buenos resultados y un alta a los 22 días desde su ingreso.

Cuba se encuentra actualmente enfrascada en el proceso de informatización de la sociedad, que incluye apropiarse de las ventajas y la cultura de los avances tecnológicos y de las info comunicaciones. Un paso importante en esta dirección podría ser el estudio y conocimiento profundo de la tecnología blockchain. La tecnología blockchain se presenta como una revolución que soluciona los problemas de vulnerabilidad que ha venido presentando la Internet, así como una posibilidad de aplicación frente a los problemas de seguridad informática indescifrable a terceros. Esta tecnología ha comenzado a impactar en diversos ámbitos más allá de la informática. A pesar de esto, los estudios existentes sobre el tema son aún insuficientes, especialmente en Cuba. Por tal motivo, se hace necesaria la investigación sobre esta tecnología disruptiva y sus aplicaciones en el sector turístico. En la presente investigación se realiza una sistematización del tema. En un primer momento, se efectúa un acercamiento al fenómeno; estableciendo su historia, principales definiciones, ventajas, desventajas y tipos de red; dado que la información sobre la evolución y características del blockchain es aún poco conocida y difundida. En un segundo capítulo se efectúa un análisis sobre sus posibles aplicaciones en el sector turístico, para finalmente desde la coyuntura económica de Cuba, evaluar sus potencialidades de uso. La presente investigación pretende ser un primer acercamiento al tema de manera tal que se difundan los potenciales usos del blockchain en el sector turístico cubano y se abran nuevas investigaciones en este sentido.
