Nonsterile Glove Use
Authors: Brankston Gabrielle , Bailey Sharon
Published: September 2023

In acute care settings with low-risk of infection transmission, discontinuing contact precautions (i.e., gloves and gown) may result in similar rates of hospital-acquired methicillin-resistant Staphylococcus aureus (MRSA) and may lower the risk of hospital-acquired vancomycin-resistant enterococci (VRE), compared to scenarios in which such precautions were employed.
Rates of late-onset infections in a neonatal intensive care unit were similar when standard infection control precautions were used compared with universal glove use.
Two guidelines recommend that nonsterile gloves should be worn for nonsterile procedures when it is anticipated that there will be contact with blood, body fluids, non-intact skin, mucous membranes, lesions, or hazardous drugs and chemicals; for environmental cleaning; and when contact precautions for infection control are in effect.

Background: Poor diet among workers accounts for 20 % of productivity loss as adequate nutrition is essential for optimum work productivity. Unfortunately, little attention is paid to the nutritional status to academics in Nigeria. Objective: This study assessed the nutritional status and nutrient adequacy of food consumed by non-academic staff in a Nigerian University. Methods: This is a cross-sectional descriptive study of 300 randomly selected non-academic staff of the Federal University of Agriculture, Abeokuta. Data were obtained on socio-demographic and socioeconomic characteristics, anthropometric parameters, and nutrient intake using pre-tested self-administered questionnaires, standard procedures, and repeated 24 – hour dietary recall. Categorical data were expressed as mean and standard deviation and inferential statistics such as Pearson Chi-square was used to determine the association between variables. Results: The mean age of the respondents was 42 ± 8.0 years with 56 % being female. The anthropometric results showed that 32 % and 20 % were overweight and obese respectively. Protein intake was inadequate among the female (32.7 %) and male (27.3 %) respondents. Vitamin A intake was (32.7 %) and (29.2 %) among the female respondents compared to male respondents with protein (27.3 %) and Vitamin A (27.3%). Male and female respondents’ mean intake of vitamin C was of 36.2 and 39.4 mg and was reduced compared to the Recommended Dietary Allowance (RDA). The food habits also revealed that several of the respondents practiced snacking (58 %), skipped meals (62 %), and did not consume fruits and vegetables (30 %). Conclusions: This study reveals that half of the respondents were overweight and obese. Inadequate intake of vitamin C and protein was considerably elevated among the respondents in this study. There is, therefore, a need for institution-based health promotion education programs and further studies to assess the dietary diversity of the respondents.

NEP 2020: EMPOWERING TEACHER IN 21st CENTURY EDUCATION
Authors:   Vaish College of Education Rohtak, Pasrija Pooja , Dhull Kamlesh , Gupta Sudesh
Published: September 2023

The world is full of competition and achieving life goals requires capable, efficient and skilled teachers to help our future generations to achieve their long and short term life goals. Rather than blaming teachers for poor classroom learning outcomes in India, NEP 2020 attributes the dire state of teacher education, recruitment, turnover and working conditions to a lack of quality and motivation among teachers. Recognizing the `power of teachers`, NEP 2020 introduced institutional reforms to help `teaching` become an attractive profession for bright and talented youth. The report proposes several reforms to empower teachers and "restore dignity and prestige" to the profession, ultimately attracting the best minds and talent to teaching as a profession. NEP 2020 will focus on active pedagogy, development of core competencies and life skills including 21st century skills, experiential learning at all levels, low-cost board exams, comprehensive scorecards, and critical and advanced students. This paper emphasizes the fact that the ambitious goals of 21st century education can be achieved by empowering teachers in all aspects of quality education, career development, independence, performance and role expectations.

The paper also tries to give insight into landscape, and topography of the site. Since this is a preliminary study of the Singar Lata site hence, deeper and elaborative analysis and interpretation are not included. However, we try to bring about essential information that will help to future research and detail study of Singar Lata site.
THE REMAINS OF THE VISHNU TEMPLE AND OTHER IMPORTANT INFORMATION
Authors:   Archaeological Survey of India, Vyas Dr. Narayan
Published: September 2023

This research paper explores the historical significance of the ancient city of Besnagar, located in Madhya Pradesh, India. Through archaeological excavations conducted by the Archaeological Survey of India, valuable artifacts and structures have been unearthed, shedding light on the city's prominence during the Mauryan and Shunga periods. Besnagar, believed to be a distorted form of Vaishya Nagar, was likely a prominent center of Vaishnavism in ancient times. Situated between the Betwa and Bes rivers, the city was protected by a nearly one-kilometer-long defensive wall on the Udayagiri Road. Outside the city walls, a large reservoir made of massive stones stored water from both rivers, contributing to the city's development. The study aims to shed light on the historical context, architectural features, and religious significance of the Vishnu Temple and other archaeological remains from the site.

Authors:   Banaras Hindu University
Published: September 2023

This research paper explores the profound impact of Hellenistic culture on the coiffures and head-dresses depicted in Gandhāra art, an artistic tradition that emerged in the northwestern region of the Indian subcontinent during the Hellenistic period. The study delves into the historical context of the Gandhāra region, where a rich blend of Greek, Persian, and local traditions created a unique cultural milieu. Drawing upon a comprehensive analysis of Gandhāra sculptures, bas-reliefs, and other evidence, the research reveals the nuanced assimilation of Hellenistic elements into the indigenous artistic conventions. It examines the intricate hairstyles, elaborate head-dresses, and distinctive ornamentation found in Gandhāra art, highlighting their unmistakable parallels to Greco-Roman aesthetics.
MULTIPLE BENEFITS OF REVITALIZING THE ANCIENT WATER-WORKS
Authors:   Dr V.S. Wakankar Archaeological Research Institute, Manuel Dr. J.
Published: September 2023

Drawing water from rivers tens of kms away or more than hundred meters depth, cannot go on with increasing frequency for long. Therefore, the well-known principle to catch water where it falls practiced in ancient times as seen in thousands of ancient waterworks spread across the country, should be revived. These systems were built centuries or even millennia before, are reusable even now, but concerted effort to revive them must be undertaken. Most of these are in heritage cities and towns and are swamped by urban landscapes. The arterial system of catchment often gets clogged up due to such development activities and the ancient water works becomes obscure and goes into oblivion. The water works which in its functional period may have catered for thousands of denizens in the vicinity as well as enriched the ecosystem and aesthetics of the area, that existed as a prototype for others to see and imitate, is fading off from public knowledge. The present article brings to fore many different types of water works across the millenniums not only to show the wisdom of the earlier people but also revival of such mechanism and replication of these would not only improve availability of water locally but also help increase groundwater recharge, growth of vegetation nearby, general aesthetics, and perhaps even tourism possibilities.

Abstract. A tropospheric O3 pollution episode over the Atlantic Coast of the Iberian Peninsula during August 2–6 in 2018 has been analyzed. The episode was characterized by a permanent wind shear throughout the entire period, making the observed ozone surface distribution especially difficult to explain. A new methodology is described analyzing upper-level atmospheric parameters, such as temperature, wind direction, wind speed, and O3 concentrations, added to the traditional use of surface parameters, using WRF-CAMx models and available surface and upper-air observations. Results indicate that the episode was characterized by a first phase of a sudden increase in O3 concentrations produced by fumigation and interregional transport processes within the Iberian Peninsula, followed by a continental O3 transport from Europe to the Atlantic Coast. An Atlantic front produced the dissipation of the episode, generating an “ozone front” heading the cold front passage across the region.
Genetic model for the color anomalies at the termination of pegmatitic gem tourmaline crystals from the island of Elba, Italy
Authors: Altieri Alessandra , Pezzotta Federico , Andreozzi Giovanni B. , Skogby Henrik , Bosi Ferdinando
Published: September 2023

Abstract. Tourmaline crystals from the island of Elba commonly display a
sharp transition to dark colors at the analogous termination due to the
incorporation of Fe and/or Mn during the latest stages of crystallization
in pegmatites. The formation of such color anomalies is related to a
dramatic physicochemical change in the crystallization environment as a
consequence of an opening of the geochemical system. However, mechanisms
that may lead to the availability of Fe and/or Mn in the residual cavity fluids
have been unclear. On the basis of chemical and spectroscopic
investigations, combined with structural and paragenetic observations of the
cavities, we propose a general genetic model in which, as a consequence of a
pocket rupture event, chemical alteration of Fe- and Mn-rich
minerals that formed early in the pegmatitic rock surrounding the cavities occurred through
leaching processes, produced by the action of the highly reactive late-stage
cavity fluids. Such processes were responsible for the release of Fe and Mn
in the geochemical system, allowing the formation of the late-stage dark-colored terminations in the tourmaline crystals. In some cavities, a high
availability of Mn and/or Fe determined the evolution of the crystals from
an initial elbaite/fluor-elbaite composition to celleriite, foitite or
schorl. This compositional evolution trend can be described by the following general
chemical substitution: XNa+ + Y(Li1.5 + Al0.5)3+ + WF− ↔ X□ + 2Y(Fe,Mn)2+ + WOH−.

Abstract. Biodegradable mulch films (BDMs) are a sustainable and promising
alternative to non-biodegradable polyethylene mulches used in crop
production systems. Nitrogen amendments in the form of fertilizers are used
by growers to enhance soil and plant-available nutrients; however, there is
limited research on how these additions impact the biodegradation of BDMs tilled
into soils. A 4-month laboratory incubation study using soil microcosms
was used to investigate the effects of inorganic (ammonium nitrate) and
organic (urea and amino acids) nitrogen application on biodegradation of
BDMs. We investigated the response of soil bacterial, fungal, and
ammonia-oxidizing microbial abundance along with soil nitrogen pools and
enzyme activities. Microcosms were comprised of soils from two diverse
climates (Knoxville, TN, USA, and Mount Vernon, WA, USA) and BioAgri, a
biodegradable mulch film made of Mater-Bi®, a bioplastic raw
material containing starch and poly(butylene adipate-co-terephthalate)
(PBAT). Both organic and inorganic nitrogen amendments inhibited mulch
biodegradation, soil bacterial abundances, and enzyme activities. The
greatest inhibition of mulch biodegradation in TN soils was observed with
urea amendment where biodegradation was reduced by about 6 % compared to
the no-nitrogen control. In WA soils, all nitrogen amendments suppressed
biodegradation by about 1 % compared to the no-nitrogen control. Ammonia
monooxygenase amoA gene abundances were increased in TN soils in all treatments
but reduced for all treatments in WA soils. However, a significantly higher
nitrate concentration and a lower ammonium concentration were seen for all nitrogen
treatments compared to no-nitrogen controls in both TN and WA. This study
suggests that the addition of nitrogen, particularly inorganic amendments, could
slow down mulch biodegradation but that mulch biodegradation does not
negatively affect soil nitrification activity.
Sensitivity analysis of wake steering optimisation for wind farm power maximisation
Authors: Gori Filippo , Laizet Sylvain , Wynn Andrew
Published: September 2023

Abstract. Modern large-scale wind farms consist of multiple turbines clustered together, usually in well-structured formations. Clustering has a number of drawbacks during a wind farm's operation, as some of the downstream turbines will inevitably operate in the wake of those upstream, with a significant reduction in power output and an increase in fatigue loads. Wake steering, a control strategy in which upstream wind turbines are misaligned with the wind to redirect their wakes away from downstream turbines, is a promising strategy to mitigate power losses. The purpose of this work is to investigate the sensitivity of open-loop wake steering optimisation in which an internal predictive wake model is used to determine the farm power output as a function of the turbine yaw angles. Three different layouts are investigated with increasing levels of complexity. A simple 2×1 farm layout under aligned conditions is first considered, allowing for a careful investigation of the sensitivity to wake models and operating conditions. A medium-complexity case of a generic 5×5 farm layout under aligned conditions is examined to enable the study of a more complex design space. The final layout investigated is the Horns Rev wind farm (80 turbines), for which there have been very few studies of the performance or sensitivity of wake steering optimisation. Overall, the results indicate a strong sensitivity of wake steering strategies to both the analytical wake model choice and the particular implementation of algorithms used for optimisation. Significant variability can be observed in both farm power improvement and optimal yaw settings, depending on the optimisation setup. Through a statistical analysis of the impact of optimiser initialisation and a study of the multi-modal and discontinuous nature of the underlying farm power objective functions, this study shows that the uncovered sensitivities represent a fundamental challenge to robustly identifying globally optimal solutions for the high-dimensional optimisation problems arising from realistic wind farm layouts. This paper proposes a simple strategy for sensitivity mitigation by introducing additional optimisation constraints, leading to higher farm power improvements and more consistent, coherent, and practicable optimal yaw angle settings.

The article is devoted to the analysis of the process of loading plant mass into the assembly chamber, carried out due to the energy of the air flow generated by the fan and the kinetic energy imparted to it by the rotor blades. Theoretical calculations performed using experimental data from the literature devoted to the study of hay-straw material pneumatic transport are presented. These calculations made it possible to determine the approximate range of the air flow for the developed hay transportation method. To determine the air pressure loss, the balance of resistance to the movement of air and material in the air duct was considered according to the Bernoulli equation for an elementary section. As a result of aerodynamic studies, the following was revealed: the dependence of the air flow velocity along the section width on the distance to the loader at different fan rotor speeds. Curves of distribution of velocities having the form of a parabola with a vertex in the middle of the air duct and the dependence of the velocities on the rotor speed were experimentally established. The obtained experimental data made it possible to evaluate the theoretical prerequisites, the possibility of using the Bernoulli equation in the calculations of transportation through the air duct of the loader

Published: September 2023

The mineral-petrographic study of the features of the formation of tin mineralization on the deposit additionally confirmed their close connection with the granite-porphyry intrusion of the Syrymbet massif at the contact with the Sharyk suite of the Riphean. The structural and tectonic position of tin mineralization is determined by confinement to protruding domes, ridges and gentle contacts of the massif. Moreover, mineralization is concentrated both in the intrusion itself and outside it – in the host rocks, using the favorable structural and lithological features of these rocks. Along with tectonics, metasomatic processes played a certain role in tin formation – greisenization, albitization, skarning, and as a result, the complex nature of rare-metal mineralization – Sn, W, Ta, Nb, Be, TR. The zoning distribution of ore elements is marked

Современные химические дезинфектанты не всегда эффективны, надёжны и экологически безопасны. При этом одни применяются как дезинфицирующие средства, другие как кожные антисептики или для профилактики инфекционных болезней у животных. Многие из них обладают побочными эффектами, такими как кумуляция в органах и тканях, аллергического и токсикологического характера. Среди природных антисептических препаратов наиболее эффективными и привлекательными являются шунгит, озон и анолит. Достаточно много публикаций в литературе о эффективном применении препаратов на их основе. Исследования проводили в лаборатории ветеринарной клиники Западно-Казахстанского аграрно-технического университета им. Жангир хана. С этой целью использовали лабораторных животных для проведения клинических и патологоанатомических исследований. Анолит, как дезинфицирующий препарат, получали используя серийную установку электрохимического синтеза стерилизирующих растворов СТЭЛ. Озон, как антисептический препарат, получали используя серийный озонатор «DICHO». Шунгит, как антисептический препарат, получали в качестве шунгитового раствора. Антисептический препарат «ОЗАН», как комплекс анолита и озона, получали путем озонирования раствора анолита в течение 5 минут. Клинические испытания проводили в соответствии с международными правилами GСP. Результаты исследования токсикологических и аллергических свойств антисептиков природного, нехимического происхождения показали, что шунгит, озон, анолит и «ОЗАН» абсолютно безвредны для организма лабораторных животных. Антисептические препараты химического происхождения и физиологический раствор (как стандарт для сравнения) обладают токсикологическими и аллергическими свойствами и вызывают гибель лабораторных животных. Об этом свидетельствуют материалы вскрытия и результаты клинических наблюдений.

Перспектива развития сельского хозяйства в Казахстане набирает огромные темпы. Идет развитие деверсификации сельского хозяйства, увеличиваются площади и под масличные культуры. На сегодняшний день одной из перспективных и востребованных масличных культур является подсолнечник, площади возделывания которого увеличиваются с каждым годом. Также подсоднечное масло является самым востребованным продуктом среди населения республики. Отсюда возникает вопрос повышения урожайности подсолнечника, включая различные технологии возделывания, тем самым адаптируя их к агрометеорологическим  и почвенным показателям региона возделывания. Цель данной работы заключалась в том, чтобы сравнительно изучить и оценить влияние минеральных удобрений на урожайность и масличность подсолнечника на Севере Казахстана. Эксперимент проводился в ТОО «Сельскохозяйственная опытная станция «Заречное» с южными маломощными черноземными почвами. Учеты и наблюдения за ростом и развитием подсолнечника проводились с использованием современных методических рекомендации. Агротехника возделывания подсолнечника в опытах рекомендованная для зоны исследования. Изучали разные варианты использования минеральных удобрений. В работе сделан вывод о важности совмещенного использования минеральных удобрений по схеме N40P40 осень+N20P20 весной при посеве+N10P10 подкормка в условиях зоны исследований увеличило урожайность и сбор масла подсолнечника до 1,34 т/га и 0,65 т/га. Указанные улучшения качества и увеличения продуктивности подсолнечника как основной масличной культуры имеют значительное значение для продовольственной безопасности и ведения устойчивого сельского хозяйства в Северном Казахстане.

Адамның экономикалық қызметі жер үсті тұщы су ресурстарын пайдаланудың артуына әкелді. Өзен бассейндеріндегі антропогендік ластануға байланысты су ресурстарының экологиялық жағдайын зерттеу қазіргі жағдайда өте маңызды.

Ластану – бұл судың сапалы сарқылуы, ол негізінен тазартылмаған немесе тазартылмаған ағынды сулардың түсуінен болады. Судың негізгі тұтынушылары өнеркәсіп пен ауыл шаруашылығы, сондай-ақ ірі қалалардың тұрғын аудандары мен өзендер мен көлдердің жағасындағы елді мекендер болып табылады. Жайық өзенінің бассейнінде елдің 75% ауыл шаруашылығына пайдаланылады, оның 60% егістік жерлер. Батыс Қазақстан облысының барлық дерлік аудандарында ауыл шаруашылығын тұрақты жүргізу Жайық өзенінен суару есебінен ғана мүмкін болып отыр.

Мақалада Жайық өзенінің жер үсті суларының гидрографиялық және гидрологиялық сипаттамалары келтірілген. Мақаланың мақсаты Жайық өзеннің экологиялық-гидрологиялық жағдайын сипаттау. Көптеген су объектілерінің сапасы стандарттарға сәйкес келмейді. Облыстың жер үсті суларында ең көп таралған - мұнай өнімдері, фенолдар, тотығатын қоспалар, металл қосылыстары, аммоний және азот азоты, сондай-ақ кейбір ластаушы заттар-лигнин және формальдегид ластаушы заттардың таралуы бүгінгі күнде Жайық өзененің экологиялық жағдайын нашарлатуда.

Several studies exist in literature on the attitude of students towards mathematics and the self-efficacy level of students in mathematics in general. However, little is seen on the attitudes of “At-Risk” students towards mathematics and their self-efficacy level in mathematics, hence this study was conducted to fill the gap in literature by examining the attitudes and self-efficacy level of the “At-Risk” students towards/in mathematics in the Upper East Region of Ghana. This investigation is a quantitative one which made use of a cross-sectional survey design to collect data from 104 “At-Risk” students who were selected using multiple sampling techniques. Adopted attitudes towards mathematics inventory by Tapia (1996) and adapted self-efficacy questionnaire by May (2009) were the instruments of data collection. The data collected were analyzed descriptively (means and standard deviations) which were compared with standard levels of interpretations in literature and judgment made. From the analysis of the data, it was found that “At-Risk” students have low mathematics self-efficacy level and moderate attitudes towards mathematics. It was therefore recommended that mathematics teachers should employ innovative and child-centered teaching approaches which have the potential of actively engaging learners during instruction in the subject to help enhance learners’ attitudes and self-efficacy level in mathematics.

Published: September 2023

The Inventory Routing Problem (IRP) has been highlighted as a valuable strategy for tackling routing and inventory problems. This paper addresses the IRP but considers the forward delivery and the use of Returnable Transport Items (RTIs) in the distribution strategy. We develop an optimization model by considering inventory routing decisions with RTIs collection (backhaul customers) of a Closed-Loop Supply Chain (CLSC) within a short-term planning horizon. RTIs consider reusable packing materials such as trays, pallets, recyclable boxes, or crates. The RTIs represent an essential asset for many industries worldwide. The solution of the model allows concluding that if RTIs are considered for the distribution process, the relationship between the inventory handling costs of both the final goods and RTIs highly determines the overall performance of the logistics system under study. The obtained results show the efficiency of the proposed optimization scheme for solving the combined IRP with RTIs, which could be applied to different real industrial cases.
Collaborative scheduling of machining-assembly in complex multiple parallel production lines environment considering kitting constraints

Published: September 2023

In multi-stage machining-assembly production, collaborative scheduling for multiple production lines can effectively improve the execution efficiency of production planning and increase the effective output of the production system. In this paper, a production scheduling mathematical model was constructed for the collaborative scheduling problem of machining-assembly multi-production lines with kitting constraints, with the optimization objectives of minimizing assembly completion time and tardiness time. For the scheduling model, the product assembly process is constrained by the machining sequence of the jobs on the machining lines. Only by collaborating on the production scheduling schemes of the machine line and the assembly line as a whole can the output efficiency of the product on the assembly line be improved. An improved hybrid multi-objective optimization algorithm named SMOEA/D is designed to solve this scheduling model. The algorithm uses adaptive parents’ selection and mutation rate strategies and integrates the Tabu search strategy for the search process in the solution space when the solution of the sub-problem has not been improved after specified search generations, to improve the local search ability and search accuracy of MOEA/D algorithm. To verify the performance of the SMOEA/D algorithm in solving machining-assembly collaborative scheduling problems in production systems with different resource configurations and scales, two sets of numerical experiments were designed, corresponding to situations where the number of operations on each production line is equal or unequal. The running results of the proposed algorithm were compared with three other well-known multi-objective algorithms. The comparison results indicate that the SMOEA/D algorithm is effective and superior for solving such problems.
Should offline retailers expand online under consumer showrooming based on the effects of intershowrooming and intrashowrooming?

Published: September 2023

This study aims to find a way to alleviate or eliminate the negative impact of showrooming on brick-and-mortar retailers. Therefore, under careful consideration of the effects of intershowrooming and intrashowrooming, this study explores whether retailers can effectively solve the negative impact of showrooming by opening online channels. Conduct a comparative study on the decision-making of dual/multi-channel supply chain members before and after the retailer opens an online channel and analyze the influence. In addition, we also explored the impact of factors such as the market scale expansion effect and internet market power structure. Research has found that regardless of the market scale expansion effect generated, it is effective for the retailer to increase profits by opening an online channel. The impact of market scale expansion is not entirely beneficial to the retailer. Under the intrashowrooming, the effect of market scale expansion may benefit the manufacturer. But what is more noteworthy is that for the manufacturer, the impact of intrashowrooming is not necessarily the greater, the better, and the manufacturer's profit may decrease as this effect increases.
Mixed-model assembly line balancing problem in multi-demand scenarios
Authors: Wang Kang , Han Qianqian , Li Zhenping
Published: September 2023

The mixed-model assembly line balancing problem (MMALBP) in multi-demand scenarios is investigated, which addresses demand fluctuations for each product in each scenario. The objective is to minimize the sum of costs associated with tasks allocation, workstation activation, and penalty costs for unbalanced workloads. A mixed integer programming model is developed to consider the constraint of workstation space capacity. A phased heuristic algorithm is designed to solve the problem. The computational results show that considering demand fluctuations in multiple demand scenarios leads to more balanced workstation loads and improved assembly line production efficiency. Finally, sensitivity analysis of important parameters is conducted to summarize the impact of parameter changes on the results and provide practical management insights.

Santa Catarina é um importante estado brasileiro produtor de bananas. Devido à doença conhecida como complexo de sigatoka é necessário que se  adotem diversas práticas de controle, como as aplicações de fungicidas, para o manejo dessa doença foliar. A adoção do sistema de pré-aviso biológico tem auxiliado os produtores na tomada de decisão quanto ao momento da realização de práticas de controle. O objetivo da adoção dos sistemas de pré-aviso é maximizar o controle da sigatoka com o menor número de aplicações de fungicidas. Desde a adaptação pela Epagri desse sistema de pré-aviso para as condições do litoral catarinense, estima-se que são realizadas ao menos duas pulverizações a menos por ciclo de produção nas regiões produtoras catarinenses, com impactos técnicos, ambientais, epidemiológicos e econômicos positivos. Neste trabalho é descrito a prática do monitoramento do pré-aviso biológico e seus impactos na cultura da bananeira em Santa Catarina, Brasil.
L’evoluzione del mercato del lavoro del comparto sanitario nel contesto della digitalizzazione dei servizi e delle prestazioni
Authors: D'Agostino Luisa , Romito Alessia
Published: September 2023

Il presente working paper presenta una sintesi dei risultati della ricerca L’evoluzione del mercato del lavoro del comparto sanitario nel contesto della digitalizzazione dei servizi e delle prestazioni. A partire dalle evidenze di una ricerca qualitativa realizzata nel 2020, questa indagine ha coinvolto direttamente i lavoratori del settore sanitario, con una rilevazione CAWI diretta a medici, infermieri e operatori sociosanitari (OSS). La finalità del nuovo studio, realizzato nel 2022, era quella di approfondire il tema delle connessioni tra invecchiamento della forza lavoro e innovazione tecnologica in un settore di servizi alla persona particolarmente significativo, sia per il progressivo aumento dell’età media dei lavoratori, sia per le opportunità di sviluppo connesse all’introduzione delle tecnologie digitali. L’evoluzione demografica di questo comparto e alcune specifiche difficoltà di turnover delle risorse umane, infatti, possono rappresentare nel medio termine un reale rischio di labour shortage, a fronte di una domanda di servizi di cura e assistenza sempre più crescente per il progressivo e veloce invecchiamento della nostra popolazione. In tale contesto, la digitalizzazione dei servizi è considerata una condizione necessaria per lo sviluppo del settore, ma la transizione digitale in sanità procede ancora molto lentamente, nonostante la spinta derivata dall’avvento della pandemia. I risultati offrono molteplici informazioni sulle condizioni di lavoro in sanità in una prospettiva di prolungamento della vita lavorativa, sulla motivazione al lavoro e i livelli di soddisfazione degli operatori, sulle loro aspettative future e sui cambiamenti determinati dall’avvento della crisi pandemica; interessanti, in una prospettiva di sviluppo della sanità digitale, sono i dati sull’uso delle nuove tecnologie, le difficoltà incontrate e le strategie adottate per superarle, sulla formazione al digitale, gli ostacoli alla partecipazione e la valutazione della sua efficacia espressa dagli operatori.
