This study aims to propose that there may be a marketable segment of guests who are willing to pay a premium for guestrooms that are cleaned using enhanced disinfection techniques beyond the normal room cleaning procedures. Room cleanliness is important to hotel guests. Some hotel brands currently offer allergy-free rooms, charging a premium for this service. However, no hotel brands currently serve the market that is willing to pay more for enhanced disinfection. This exploratory study investigates whether there is such a segment and, if so, what price premium these customers are willing to pay for enhanced disinfection.

Survey methods were used to determine the consumer’s perceptions of hotel guestroom cleanliness; the effectiveness of traditional and enhanced cleaning methods; and willingness to pay for enhanced guestroom disinfection.

Younger travelers and female travelers of all ages may be willing to pay a significant price premium for enhanced disinfection of a hotel guestroom.

The survey instrument was administered via the Internet, limiting the sample. The study participants were not asked about hotel brand; thus, the results could not be analyzed by brand or service level.

Past research focuses only on traditional cleaning methods. This article provides a template for the hotel industry to explore the feasibility of offering enhanced cleanliness as a revenue-generating amenity.

The disinfection robot developed by the authors and team focuses on achieving fast and precise disinfection under a given or specific disinfection zone. This looks to solve problems with traditional robots that pay less attention to the level, efficiency and zones of disinfection. To effectively support and guarantee normal running for the whole system, a digital twin system is applied to the disinfection robot. This study aims to achieve fast, precise and thorough disinfection via the developed mobile robot.

The designed robot is composed primarily of the following three parts: a mobile platform, a six-axis robotic arm and a ultraviolet-C (UVC) LED array. The UVC LED array is installed on the end-effector to achieve large-scale, precise manipulation. The adoption of all types of advanced sensors and the development of an intuitive and user-friendly client interface are helpful in achieving remote control, path planning, data monitoring and custom disinfection functions.

Disinfection of three different locations in the laboratory was performed; the dosage distribution of the surface as radiated by the UVC robot was detected; and feasibility of development was validated.

The developed disinfection robot achieved fast, precise and thorough disinfection for a given or specific disinfection zone.

Leafy vegetables may get contaminated with pathogens through the use of irrigation water during open field cultivation. The main control option to prevent this contamination is the use of disinfection technologies that will reduce the pathogenic load of the irrigation water. Several technologies, either chemical or physical, are available for disinfection, which were gathered from the literature and European Union (EU) projects. The purpose of this paper is to prioritise these technologies.

A feasibility study was performed to identify the most promising disinfection technology considering 12 different criteria. A two-tier approach was used in which the technologies were first evaluated based on three criteria: legal status, effectiveness and technology readiness level (TRL). Only the technologies that reached pre-set thresholds for these three criteria were then evaluated in the second tier.

The evaluation showed that the most promising technologies after the tier-2 evaluation were ultrasound, microfiltration, ultraviolet and ozone. The study showed that the followed approach enabled prioritising disinfection technologies allowing for selecting the most promising technologies that can be tested further on a possible application during primary production to prevent possible food safety issues in leafy vegetables.

The overview is not an exhaustive list of disinfection technologies available rather only those technologies that seemed promising for application in horticulture were addressed. Some technologies may, thus, have been missed. Nevertheless, a total of 12 single and seven combined technologies were evaluated.

This is the first study that uses a structured approach to prioritise a broad range of possible water disinfection technologies for use at primary production.

This paper aims to contribute to the literature investigating hotel customers’ preventive behavior during the COVID-19. Because there is no timely research discussing cleaning and disinfection services as a premium service in China, the authors conducted research to examine customers’ perceptions based on the information–motivation–behavioral skills (IMB) model and to explore potential marketing exits. Moreover, based on the price-sensitive measurement, this study reveals the price range and optimal price of the service, which could assess the feasibility of the service and balance the operation cost.

An internet-based, self-reported survey was designed to collect the data during the outbreak of COVID-19 in April 2020. The yield was 874 usable and valid responses, which were purposefully analyzed using confirmatory factor analysis and structural equation modeling.

The results indicate a significant influence of dimensions (information, motivation, health behavior skills) on hotel customers’ preventive behavior regarding purchase intention of cleaning and disinfection service. The optimal price of this service is 20% of the average room rate, and the range of acceptable prices is 15% of the average room rate.

The present study represents academic attempts to contribute to the literature by applying the IMB model to consumer behavior in a hotel industry context, emphasizing the importance of each dimension in behavioral intention during the current ongoing global issue. Additionally, the results indicate that the hotel industry could consider satisfying the needs of this market based on the suggested price.

A novel modelling approach is proposed to study ozone distribution and destruction in indoor spaces. The level of ozone gas concentration in the air, confined within an indoor space during an ozone-based disinfection process, is analysed. The purpose of this work is to investigate how ozone is distributed in time within an enclosed space.

A computational methodology for predicting the space- and time-dependent ozone concentration within the room across the consecutive steps of the disinfection process (generation, dwelling and destruction modes) is proposed. The emission and removal of ozone from the air volume are possible by means of a generator located in the middle of the room. This model also accounts for ozone reactions and decay kinetics, and gravity effect on the air.

This work is validated against experimental measurements at different locations in the room during the disinfection cycle. The numerical results are in good agreement with the experimental data. This comparison proves that the presented methodology is able to provide accurate predictions of the time evolution of ozone concentration at different locations of the enclosed space.

This study introduces a novel computational methodology describing solute transport by turbulent flow for predicting the level of ozone concentration within a closed room during a COVID-19 disinfection process. A parametric study is carried out to evaluate the impact of system settings on the time variation of ozone concentration within the space considered.

The purpose of the presented IoT based sensor-fusion assistive technology for COVID-19 disinfection termed as “Smart epidemic tunnel” is to protect an individual using an automatic sanitizer spray system equipped with a sanitizer sensing unit based on individual using an automatic sanitizer spray system equipped with a sanitizer sensing unit based on human motion detection.

The presented research work discusses a smart epidemic tunnel that can assist an individual in immediate disinfection from COVID-19 infections. The authors have presented a sensor-fusion-based automatic sanitizer tunnel that detects a human using an ultrasonic sensor from the height of 1.5 feet and disinfects him/her using the spread of a sanitizer spray. The presented smart tunnel operates using a solar cell during the day time and switched to a solar power-bank power mode during night timings using a light-dependent register sensing unit.

The investigation results validate the performance evaluation of the presented smart epidemic tunnel mechanism. The presented smart tunnel can prevent or disinfect an outsider who is entering a particular building or a premise from COVID-19 infection possibilities. Furthermore, it has also been observed that the presented sensor-fusion-based mechanism can disinfect a person in a time of span of just 10 s. The presented smart epidemic tunnel is embedded with an intelligent sanitizer sensing unit which stores the essential information in a cloud platform such as Google Fire-base. Thus, the proposed system favours society by saving time and helps in lowering the spread of coronavirus. It also provides daily, weekly and monthly reports of the counts of individuals, along with in-out timestamps and power usage reports.

The presented system has been designed and developed after the lock-down period to disinfect an individual from the possibility of COVID-19 infections.

The presented smart epidemic tunnel reduced the possibility by disinfecting an outside individual/COVID-19 suspect from spreading the COVID-19 infections in a particular building or a premise.

The presented system is an original work done by all the authors which have been installed at the Symbiosis Institute of Technology premise and have undergone rigorous experimentation and testing by the authors and end-users.

Disinfecting laundry processes are essential to avoid contamination of laundering machines and linen during commercial laundry reprocessing in the health care sector. Recently a bacteriophage‐charged bioindicator has been developed using MS2 as surrogate virus for testing of low‐temperature disinfecting laundry processing on efficacy against viruses related to practice. This paper therefore aims to investigate application of MS2‐bioindicators in chemothermal processes under practical conditions (phase 2/step 2) and in practice (phase 3).

The experimental design was developed and modified according to the German Society for Hygiene and Microbiology (DGHM) Standard Methods for Testing Chemical Disinfection Processes. Tests under practical conditions were performed at 60°C and 70°C. Additional tests in tunnel washers were carried out at 60°C and 70°C. In all experiments validated disinfecting laundry processes, recommended for bactericidal and virucidal performance (categories A and B), were applied.

The results show a temperature‐dependent gradual efficacy against the test virus MS2 up to reduction values of more than 8 log₁₀‐steps. Therefore MS2‐bioindicators prove to be suitable as a tool to determine the performance of disinfection procedures against viruses in practice.

Phage‐charged bioindicators may be a tool to provide further insights into the reliability of antiviral laundry processes for health care quality management and for infection control.

The aim of the paper is to explore how multiple modes of knowledge play out in the consolidation of nursing procedures in construction of “local universality”. The paper seeks to explore processes where nurses negotiate universal procedures that are to become local standards in a hospital.

The paper is based on a case study design. Working group sessions, where the activity was to consolidate different versions of nursing procedures were observed and videotaped. For this paper, transcribed videotaped observations, where tension‐laden situations were identified, are subject to interaction analysis.

In the negotiations to construct standards, multiple modes of knowledge play out; personal experience, collective expertise and formalized knowledge. The paper demonstrates the contributions these modes of knowledge make in a process of standardization. This shows that standards, as such, do not stay universal for very long, but are constructed as “local universalities”.

The study elaborates on discursive negotiations of procedures to illustrate how local universality plays out in processes to constitute standards. It is a limitation because how the local universality plays out in clinical work, or make claims about practice transformation, cannot be described.

The paper shows the necessity of confronting standardized procedures through multiple modes of knowledge. The paper exemplifies productive interactions in the construction of local universality, and how professionals account for practice when facing formal and standardized procedures.

The preventive health institutions were founded in Istanbul as a result of the Ottoman Empire's policy to fight epidemic diseases that affected all parts of the world in the nineteenth century. The purpose of this paper is to examine the historical and current state of these heritage buildings.

Through the original documents, photographs and floor plans dating nineteenth and early twentieth century obtained from the Ottoman State Archives, historical development and architectural features of the buildings have been identified. And the original geographical locations of the buildings, especially the destroyed ones, are investigated by the historic maps. Plan and façade features, construction techniques are examined according to the information gained from the newspapers, journals and health annuals of the period.

This paper presents the findings of an MSc thesis conducted on the historical approach of preventive health institutions and preservation problems of the Pendik Institute of Veterinary Bacteriology. In the study, it has been examined that institutes in five different functions which were established after the foundation of the Quarantine Council in 1838 with parallel to the course of epidemics and scientific development in the West. In Istanbul, eight quarantine stations, three disinfection stations, one rabies laboratory, one vaccination institute and five bacteriology institutes have been documented. Some of these institutions fell out of use due to the loss of their original function and have been abandoned and demolished, some of them have survived with functional changes. The extant samples of these preventive health institutions are studied on the purpose of investigating their conditions of preservation.

Late Ottoman period preventive health institutions in Istanbul have been the subject of the researches within the field of medicine and science history to date. There is no study in Turkish and International literature discussing these institutions in terms of architecture. In the study these buildings have been thoroughly examined based on their architectural features and heritage values. The glass plate photographs of the Pendik Institute of Veterinary Bacteriology, floor plans and some photographs of the other institutions which are obtained from Ottoman State Archives and newspapers of the period have been published for the first time in this paper.

The ability to manage the COVID-19 pandemic is contingent upon the ability to effectively manage its heterogeneous knowledge resources. Knowledge mapping represents a great opportunity to create value by bringing stakeholders together, facilitating comprehensive collaboration and facilitating broader in-depth knowledge sharing and transfer. However, identifying and analysing critical knowledge areas is one of the most important steps when creating a knowledge map. Therefore, the purpose of this paper is to appraise the critical knowledge areas for managing COVID-19, and thereby enhance decision-making in tackling the consequences of the pandemic.

The methodological approach for this study is a critical literature review, covering publications on knowledge management, knowledge mapping and COVID-19. EBSCOhost, PubMed, Scopus, Science Direct, TRID, Web of Science and Wiley Online Library were searched for full text, peer-reviewed articles written in English that investigated on critical knowledge areas for managing the spread of COVID-19. After full screening, 21 articles met the criteria for inclusion and were analysed and reported.

The study revealed seven critical knowledge areas for managing the COVID-19 pandemic. These are cleaning and disinfection; training, education and communication; reporting guidance and updates; testing; infection control measures, personal protective equipment; and potential COVID-19 transmission in health and other care settings. The study developed a concept knowledge map illustrating areas of critical knowledge which decision-makers need to be aware of.

Providing decision-makers with access to key knowledge during the COVID-19 pandemic seems to be crucial for effective decision-making. This study has provided insights for the professionals and decision-makers identifying the critical knowledge areas for managing the COVID-19 pandemic.

The study advances the literature on knowledge management and builds a theoretical link with the management of public health emergencies. Additionally, the findings support the theoretical position that knowledge maps facilitate decision-making and help users to identify critical knowledge areas easily and effectively.

This study fills gaps in the existing literature by providing an explicit representation of know-how for managing the COVID-19 pandemic. This paper uses an objective and qualitative approach by reviewing related publications, reports and guidelines in the analysis. The concept map illustrates the critical knowledge areas for managing the COVID-19 pandemic.
