Light is known to exert powerful effects on behavior and physiology, including upon the amount and distribution of activity across the day/night cycle. Here we use home cage activity monitoring to measure the effect of differences in home cage light spectrum and intensity on key circadian activity parameters in mice. Due to the relative positioning of any individually ventilated cage (IVC) with regard to the animal facility lighting, notable differences in light intensity occur across the IVC rack. Although all mice were found to be entrained, significant differences in the timing of activity onset and differences in activity levels were found between mice housed in standard versus red filtering cages. Furthermore, by calculating the effective irradiance based upon the known mouse photopigments, a significant relationship between light intensity and key circadian parameters are shown. Perhaps unsurprisingly given the important role of the circadian photopigment melanopsin in circadian entrainment, melanopic illuminance is shown to correlate more strongly with key circadian activity parameters than photopic lux. Collectively, our results suggest that differences in light intensity may reflect an uncharacterized source of variation in laboratory rodent research, with potential consequences for reproducibility. Room design and layout vary within and between facilities, and caging design and lighting location relative to cage position can be highly variable. We suggest that cage position should be factored into experimental design, and wherever possible, experimental lighting conditions should be characterized as a way of accounting for this source of variation.

A successful exhibition cannot be separated from the proper arrangement of the exhibition space. A good exhibition space arrangement will generate interest from exhibition visitors. Moreover, what if the exhibition is a museum exhibition. The arrangement of museum exhibitions requires a more complex arrangement. South Sumatra Province held a joint exhibition which various state museums throughout South Sumatra attended. Because various museums attend it, a good exhibition space arrangement is needed to present an optimal exhibition space so that it is attractive to visitors and is not inferior to other museums in the exhibition. Therefore, this service aims to assist dr.AK.Gani Museum as a partner to organize its exhibition space to make it more optimal. The community service activities offered at this activity are assistance in designing informative brochures and showing off collections. Exhibition activities went well and safely following health protocols during the COVID-19 pandemic, attended by various students and the general public. The activity method includes focus group discussions, exhibition room design, and effective exhibition space design implementation to produce the dr.AK.Gani Museum exhibition design has been implemented at the 2020 Joint Exhibition at the South Sumatra State Museum

A student can study well if there is a good place to study as well. Likewise with reading, a person needs concentration to read. Service room design is necessitated in the reading room because it affects one’s reading comfort. Utsman bin Affan library UMI Makassar is a place for students to study. Students’ complaints and problems that are experienced when using the library service room are in the form of uncomfortable facilities, no closed rooms, and other complaints. In reference to these problems, a study was carried out in accordance with the students’ complaints by employing Kansei Engineering approach. Kansei Engineering is a consumer-oriented ergonomic technology which enables the consumer’s image or feeling to unite with the service design process of a product. By utilizing this method, product strategy and concept creation in the design of a product or service can be determined. The final results of Utsman bin Affan UMI Makassar library service room which was obtained based on the Kansei Engineering method are an open service room, large display, reading room, multimedia room, collection room, green and white colors, 3D motif and glossy texture. In addition to the main specifications of the library, there is also an additional item supporting the service room, which is a partition made of glass that gives the impression of being open to the room although it is still divided into different spaces.

Abstract International Maritime Organization (IMO) has published technical circular (MSC/Circular. 834) including nonmandatory guidelines with five main criteria about engine room layout, design, and arrangement. The purpose of this study is to present the most important priority criteria of seafarers about engine room design according to the criteria from IMO MSC/Circular.834 guidelines. Since there are no obligations, the priority and importance of these criteria are not clearly emphasized. Therefore, the determination of seafarers’ priorities for arrangement in terms of safety and efficiency become important to make decision. For this, fuzzy Analytic Hierarchy Process (AHP) technique, which is one of the most used fuzzy Multiple Criteria Decision Making (MCDM)methods is employed. Introduction Maritime transportation, known for oldest and widespread transportation around the world, with 11 billion tons weight and 80% rate of world trade volume (UNCTAD 2019). Maritime transportation has many components and one of the most important and effective parts of these components are ships and seafarers. Because of the difficulty of ship conditions, ships should be present optimum working conditions for seafarers in order to achieve effective and safe operations on board. At the present time, there are previous studies about the difficulty of working studies on board. It is a scientific and cultural fact that seafarers are under higher risk of working conditions comparing to other jobs (Bloor et al. 2000; Havold 2005; Hetherington et al. 2006; Mallam et al. 2015). Due to this reason, International Maritime Organization (IMO) has made various regulations for years in order to improve seafarers’ safety and efficiency on board. One of the goals of these regulations is to design optimum working conditions on board for seafarers. Based on complex structure and having various danger conditions, engine room design is considerable to ensure safety and efficiency for engine room department seafarers.

Hospital ratings reflect patient satisfaction, consumer perception of care, and create the context for quality improvement in healthcare settings. Despite an abundance of studies on the health benefits of the presence and content of window views, there is a gap in research examining how these features may impact patient satisfaction and consumer perceptions of the quality of care received. A quantitative exploratory study collected data from 652 participants regarding their previous stay in the hospital, their perception of windows in their room, and their perception of their room, the hospital, and the quality of care received. On a scale of 0–10, participants with access to windows gave a 1-unit higher rating for the hospital. Access to window views from their bed provided a 1-unit increase, and having a view to green spaces resulted in a 2-unit increase in hospital ratings. Statistically significant results were also found for room ratings and care ratings. Windows in the patient rooms impact the key patient satisfaction measures and patient experience during the hospital stay. Patient room design, bed set up, and quantity and quality of window views may play an important role in shaping the patient’s experience.

The COVID-19 pandemic pushed dental health officials around the world to reassess and adjust their existing healthcare practices. As studies on controlled COVID-19 transmission remain challenging, this review focuses on particles that can carry the virus and relevant approaches to mitigate the risk of pathogen transmission in dental offices. This review gives an overview of particles generated in clinical settings and how size influences their distribution, concentration, and generation route. A wide array of pertinent particle characterization and counting methods are reviewed, along with their working range, reliability, and limitations. This is followed by a focus on the effectiveness of personal protective equipment (PPE) and face shields in protecting patients and dentists from aerosols. Direct studies on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are still limited, but the literature supports the use of masks as an important and effective non-pharmaceutical preventive measure that could reduce the risk of contracting a respiratory infection by up to 20%. In addition to discussing about PPE used by most dental care professionals, this review describes other ways by which dental offices can protect patients and dental office personnel, which includes modification of the existing room design, dental equipment, and heating, ventilation, and air conditioning (HVAC) system. More affordable modifications include positioning a high-efficiency particulate air (HEPA) unit within proximity of the patient's chair or using ultraviolet germicidal irradiation in conjunction with ventilation. Additionally, portable fans could be used to direct airflow in one direction, first through the staff working areas and then through the patient treatment areas, which could decrease the number of airborne particles in dental offices. This review concludes that there is a need for greater awareness amongst dental practitioners about the relationship between particle dynamics and clinical dentistry, and additional research is needed to fill the broad gaps of knowledge in this field.

Children with cancer are frequently hospitalized during diagnosis and treatment. Since the early 1980s, parents are co-admitted because their presence positively affects children’s adjustment to hospitalization and reduces post-traumatic stress. However, the size and overall architectural design of the rooms were never adapted to the doubling of the occupancy rate. Since studies show that many parents experience high levels of distress due to their child’s illness, the purpose of this study was to investigate the impact of the architecture of the aged patient rooms on parental distress. A video observation targeted parent–child interaction related to five architectural determinants: (a) function and place of interaction, (b) distance between parent and child, (c) used space, (d) withdrawal, and (e) duration of the interaction. A total of 22 families were included in two Dutch children’s hospitals. Results show a significant association between parental distress and three architectural determinants: The less anxious the parents were and the better they estimated their child’s well-being, the more distance they created between themselves and their child, and the more space, privacy, and withdrawal options were used. These findings are discussed within a new patient room typology, the parent–child patient unit (PCPU), which reacts to the evident association of parental distress and the design.

AbstractAn experiment was conducted to compare museum visitors’ gaze patterns using mobile eye-trackers, whilst they were engaging with a physical and a virtual reality (VR) installation of Piet Mondrian’s Neo-plasticist room design. Visitors’ eye movements produced approximately 25,000 fixations and were analysed using linear mixed-effects models. Absolute and area-normalized dwell time analyses yielded mostly non-significant main effects of the environment, indicating similarity of visual exploration patterns between physical and VR settings. One major difference observed was the decrease of average fixation duration in VR, where visitors tended to more rapidly switch focus in this environment with shorter bursts of attentional focus. The experiment demonstrated the ability to compare gaze data between physical and virtual environments as a proxy to measure the similarity of aesthetic experience. Similarity of viewing patterns along with questionnaire results suggested that virtual galleries can be treated as ecologically valid environments that are parallel to physical art galleries.
