Exposure to indoor air pollutants poses a significant health risk, contributing to various ailments such as respiratory and cardiovascular diseases. These unhealthy consequences are specifically alarming for athletes during exercise due to their higher respiratory rate. Therefore, studying, predicting and curtailing exposure to indoor air contaminants during athletic activities is essential for fitness facilities. The objective of this study is to develop a neural network model designed for predicting optimal (in terms of health) occupancy intervals using monitored indoor air quality (IAQ) data.

This research study presents an innovative approach employing a long short-term memory (LSTM) recurrent neural network (RNN) to determine optimal occupancy intervals for ensuring the safety and well-being of occupants. The dataset was collected over a 3-month monitoring campaign, encompassing 15 meteorological and indoor environmental parameters monitored. All the parameters were monitored in 5-min intervals, resulting in a total of 77,520 data points. The dataset collection parameters included the building’s ventilation methods as well as the level of occupancy. Initial preprocessing involved computing the correlation matrix and identifying highly correlated variables to serve as inputs for the LSTM network model.

The findings underscore the efficacy of the proposed artificial intelligence model in forecasting indoor conditions, yielding highly specific predicted time slots. Using the training dataset and established threshold values, the model effectively identifies benign periods for occupancy. Validation of the predicted time slots is conducted utilizing features chosen from the correlation matrix and their corresponding standard ranges. Essentially, this process determines the ratio of recommended to non-recommended timing intervals.

Humans do not have the capacity to process this data and make such a relevant decision, though the complexity of the parameters of IAQ imposes significant barriers to human decision-making, artificial intelligence and machine learning systems, which are different. Present research utilizing multilayer perceptron (MLP) and LSTM algorithms for evaluating indoor air pollution levels lacks the capability to predict specific time slots. This study aims to fill this gap in evaluation methodologies. Therefore, the utilized LSTM-RNN model can provide a day-ahead prediction of indoor air pollutants, making its competency far beyond the human being’s and regular sensors' capacities.

This paper aims to review and assess the sustainable design and management considerations affecting workplaces’ productivity in Saudi Arabia.

The study uses a mixed approach, commencing with literature review, development and pilot-testing of a structured questionnaire instrument to assess design and management considerations towards productively sustainable workplaces (PSWs). In total, 31 considerations affecting sustainable workplaces’ productivity were identified and clustered under five main directions. A collective group of stakeholders, including architects/engineers (A/E), workplace users and facilities managers, were approached to correlate and compare their individual assessment of the identified PSWs. The relative importance index (RII) for each of the PSW considerations is correlated and discussed.

A high level of agreement is recognized among the three stakeholder groups for PSWs considerations’ assessed rankings. The provision of sufficient ventilation and illumination levels, availability of occupational health, security and safety, availability of ergonomically oriented technological infrastructure, availability of formal and informal meeting spaces, efficient space utilization and ergonomic workstations are all ranked highest in importance as design considerations towards PSWs.

The study stems from the need to understand how the PSWs’ design and management considerations are perceived by all streams of stakeholders. The findings identify the considerations’ importance for prioritization on PSWs’ investments.

Indoor environmental quality (IEQ) in buildings has an impact on people’s health, productivity and comfort. Maintaining the highest possible IEQ level in complex buildings, such as health care, is difficult due to economic and organizational constraints. This study aims to categorize the vicinities in a typical health-care facility in terms of importance and criticality in relation to the various IEQ factors, as well as to develop an IEQ assessment procedure.

A comprehensive literature review, established standards and structured interviews with industrial hygiene professionals in health-care settings were used in this study. To test the applicability of the developed IEQ assessment procedure, a pilot study was conducted in an existing health-care facility.

This study categorized health-care facilities into various vicinities and discovered three respondents group had varying IEQ perceptions (facility managers, environmental health specialists and nurses). According to the findings, indoor air quality is the most important and dominant factor influencing overall IEQ in health-care facilities. The trial application of the framework shows that much work is needed to improve the level of response and readiness of facility management and occupants to allow for the effective use of the developed procedure.

Previous research did not include a detailed categorization of vicinities in health-care buildings based on IEQ requirements. The findings of this study will help to close this knowledge gap and guide facility managers and operators in recognizing the relative importance of different IEQ factors, maintaining functional requirements and identifying priorities when developing maintenance and operational procedures and allocating resources.

This study aims to determine, examine and rank the factors/subfactors that may influence the students’ productivity through different design phases inside the architectural design studio. In addition, it examines the relationships/interrelationships between these factors and students’ educational level.

This research used different research methods: literature review, semi-structured interview and questionnaire (n = 420), and different statistical analysis methods: descriptive, comparative and Pearson r correlation analysis.

This research found that physical and administration factors significantly influence students’ productivity, followed by social and psychological, design and operational, personal and natural environmental factors. Additionally, thermal comfort was the subfactor most affecting the students’ productivity through all design phases. This research found that there were significant strong/very strong positive linear relationships/interrelationships between the student’s education level and all the factors that may increase the students’ productivity (r > 0.647), and between all the factors that may increase the students’ productivity (r ranged between 0.521 and 0.873). The factors affecting students’ productivity in the architectural design studio must be considered as a pool when designing architectural spaces.

The research findings provide the stakeholders, researchers, architects and facilities managers in architectural education with information on improving students’ productivity and enhancing the learning experience that positively affects their confidence and well-being in the design studio. In addition, this research provides information to develop guidelines for evaluating, designing and/or improving design studio environments that facilitate students’ productivity.

This research provides valuable insights into the students’ productivity during design study and how to prepare students for future professional roles, increase their involvement in their design development process and improve the quality of design education. The productivity of the architectural design students during the design studio hours plays a significant role in improving the architectural learning process. Enhancing students’ productivity during design studio hours promotes their design skills and future abilities of a problem-solving approach, which enhances the profession, provides an effective and comfortable student work environment, reduces the students’ stress inside the design studio and meets the students’ physical and emotional needs.

Due to land resource scarcity, sustainable urban development in high-density cities has long been challenging. As such, many cities are formulating plans to “dig deep”, resulting in more citizens working and/or staying underground for longer periods of time. However, owing to the particularities of underground space, the factors involved in the creation of a healthy environment are different from those involved in aboveground developments. This study thus aims to investigate the influences of various underground environment factors on users' health through a holistic approach.

To achieve this aim, 12 underground sites and 12 corresponding aboveground sites are selected for a large-scale questionnaire survey, resulting in 651 survey samples. The survey covers post-occupancy evaluation of health (physical and psychosocial), underground environmental quality (visual, thermal, acoustic comfort, indoor air quality and ventilation), space design and greenery. Independent-sample T-test, Pearson correlation, multiple regression modelling and structural equation modelling are used to investigate whether significant differences exist between health of underground and aboveground users, and to develop an underground environment-health model for unveiling the significant associations between underground environment factors and users' health. To cross validate the results, an objective field measurement study is further conducted on six underground sites. The objective measurement results are used to cross validate the survey results.

The questionnaire results provide the following evidence: (1) health of underground users is significantly poorer than that of their aboveground counterparts; (2) underground development users' health is significantly affected by space design, greenery and environmental quality in terms of thermal comfort, indoor air quality, ventilation and acoustic comfort but not visual comfort; and (3) amongst the various identified factors, space design has the strongest predicting effects on human health. The field study echoes the survey findings and further unveils the relationships between different environmental factors and human health.

The results shed light on the importance of distinguishing between underground developments and aboveground ones in various guidelines and standards, especially those related to space management.

Heating, ventilating, air-conditioning and cooling (HVAC) systems are crucial in daily health-care facility services. Design-related defects can lead to maintenance issues, causing service disruptions and cost overruns. These defects can be avoided if a link between the early design stages and maintenance feedback is established. This study aims to use experts’ experience in HVAC maintenance in health-care facilities to list and evaluate the risk of each maintenance issue caused by a design defect, supported by the literature.

Following semistructured interviews with experts, 41 maintenance issues were identified as the most encountered issues. Subsequently, a survey was conducted in which 44 participants evaluated the probability and impact of each design-caused issue.

Chillers were identified as the HVAC components most prone to design defects and cost impact. However, air distribution ducts and air handling units are the most critical HVAC components for maintaining healthy conditions inside health-care facilities.

The unavailability of comprehensive data on the cost impacts of all design-related defects from multiple health-care facilities limits the ability of HVAC designers to furnish case studies and quantitative approaches.

This study helps HVAC designers acquire prior knowledge of decisions that may have led to unnecessary and avoidable maintenance. These design-related maintenance issues may cause unfavorable health and cost consequences.

This purpose of this study was to investigate the role of nurses’ resilience as an indicator of their mental health on sick leave absenteeism during the COVID-19 pandemic.

This descriptive-analytical study was conducted in 2020 to identify the predictors of absenteeism among 260 nurses working in two training hospitals delivering specialized services in the treatment of COVID-19 patients. Data was collected through the use of standard questionnaires including demographic information, nurses’ resilience, intention for job turnover and absenteeism from the workplace. To predict sick leave absenteeism, regression analyses were implemented.

Study results revealed that the most influencing features for predicting the probability of taking sick leave among nurses were marital status, tenacity, age, work experience and optimism. Logistic regression also depicted that nurses who had less faith in God or less self-control were more likely to take sick leave.

The resilience of nurses working in the COVID-19 pandemic was relatively low, which needs careful consideration to apply for organizational support. Main challenge that most of the health systems face include an inadequate supply of nurses which consequently lead to reduced efficiency, poor quality of care and decreased job performance. Thus, hospital managers need to put appropriate managerial interventions into practice, such as building a pleasant and healthy work environment, to improve nurses’ resilience in response to heavy workloads and stressful conditions.

To the best of the authors’ knowledge, this is the first study to examine such a relationship, thus contributing findings will provide a clear contribution to nursing management and decision-making processes. Resilience is an important factor for nurses who constantly face challenging situations in a multifaceted health-care system.

Burnout is defined as the syndrome that causes emotional exhaustion, depersonalisation and reduction in personal achievement, and concerns people-oriented professions. This study explores the impact of burnout on the health, social and family life of mental health nurses.

A qualitative method with face-to-face semi-structured in-depth interviews was implemented with 16 mental health nurses working in Athens, Greece.

Nursing staff experience emotional exhaustion intensely due to stress since psychiatric patients require constant contact and communication and increased needs that workers have to meet. Regarding the feeling of personal achievement, they evaluated their performance positively and were satisfied with the effectiveness of the care provided. Regarding depersonalisation, the interviewees stated that they do experience it; however, in their majority they express that they do not wish to distance themselves from their duties. Their social and family life is not significantly affected and communication and support from family members is highly rated.

The research has focused on samples of nurses without mentioning their specialisation, while few studies in Greece have focused on the phenomenon in mental health nurses using qualitative research methods. This study aimed to fill this gap in the literature by examining burnout syndrome using a qualitative methodology.

Parents of children with intellectual and developmental disabilities are frequently given news that is difficult to hear and can be very traumatic. Whether receiving an initial diagnosis for their baby or learning about guardianship options for their adult child, emotional reactions almost always occur, especially because of the interdependent relationship they have with their child. These emotions likely impact the meaning parents give to information and decisions they make for their children throughout their lives. Medical, education, and other support providers sometimes assume parents can objectively receive information that frequently is communicated in a technical and clinical way. They may not give parents the time to emotionally process what they have learned, limiting their ability to care for their child. This chapter presents the results from a series of focus groups with 21 parents of children with intellectual and developmental disabilities of varying ages. The participants discussed their emotional reactions to information communicated to them about medical, educational and social concerns related to their children. In addition, they discussed how emotions impacted their information processing and sensemaking as they gave meaning to what they learned. Analysis of the results identified eight emotion-based information processing and sensemaking themes that are described in detail. The discussion section provides an enhanced explanation for emotion's role in parental information processing and sensemaking. In addition, recommendations for providers communicating emotional information to parents are provided.

Despite Bangladesh’s continued attempts, gender disparity in the workplace has long been a concern, and progress has been slow. Studies conducted earlier indicate that working women in Bangladesh experience an unwelcoming work environment, leading to unequal pay and limited opportunities for their career growth. Academic literature focuses little on the connection between gender and the physical work environment. This chapter focuses on the connection between the masculinist culture of organizations, how work is carried out, and workplaces are set up, illuminating the crucial role played by the built environment in maintaining gender equality. Infrastructure, spatial design, safety measures, amenities, and the biased culture often influence the obstacles to women’s long-term success in the workplace. This chapter investigates and comprehends the constraints female employees encounter in Bangladesh during their work by scrutinizing the influence of the physical space and the biased socio-psychological environment. As women’s long-term professional progress depends on how these elements are interrelated, improving the environment is the first step toward a fairer and more empowered work environment. A qualitative approach has been used in this study. Seventy-eight Bangladeshi graduate, working women have participated in this research. The results show that, regardless of efforts, the environment in Bangladeshi workplaces is inhospitable, directly affecting women’s careers. Building a welcoming workspace accommodating all genders is crucial for creating gender parity and promoting long-term professional growth. Therefore, this research suggests that the government should capitalize on successful efforts and investigate alternative techniques to improve this issue.
