Electricity use for lighting, ventilation and appliances can typically in WesternEurope be reduced by 80% and still provide the services needed. The strategies for achieving......It is possible within some decades to achieve environmental sustainability in the building sector and at the same time provide a comfortable and healthy life for all Europeans as well as leaving that option open for other people in the world.Buildings are charcterized by having the longest lifetime...... of all capital in our societies, often more than a hundred years. For that reason they should never be designed on the bases of just present cheap energy supply and energy system, but with the long term outlook and risks in mind. New buildings can be designed to require essentially no space heating...

    Full Text Available The building that houses the Mirvac School of Sustainable Development at Bond University is the first educational building to achieve a six Green Star rating from the Green Building Council of Australia. It has won numerous awards since opening in August 2008 including being judged the RICS (Royal Institution of Chartered Surveyors Sustainable Building of 2009. After more than two years in use a post-occupancy evaluation study was carried out to assess the performance of the building from the viewpoint of the users; both resident staff and transient students. Results for factors such as lighting, thermal comfort, noise and air quality. were compared to benchmarks established by the Usable Buildings Trust. The evaluation also assessed the occupants’ perceptions of the building’s impact on their own productivity. Users generally find the building provides a comfortable work environment although a number of areas of performance were noted as posing some concerns. These included intrusive noise in some parts of the building and some issues with glare in daylit teaching spaces. Such concerns were found to be in accord with the results of previous studies and they highlight some recurrent problems in “green” buildings designed to maximise the use of natural ventilation and natural light. These design challenges and how occupant satisfaction is to be measured and benchmarked are also discussed in the context of this comparative building study.

    Kokorikou, A; Vink, P; de Pauw, I C; Braca, A

    2016-07-19

    Making a lightweight seat that is also comfortable can be contradictory because usually comfort improvement means adding a feature (e.g. headrest, adjustable lumbar support, movable armrests, integrated massage systems, etc.), which makes seats heavier. This paper explores the design of an economy class aircraft seat that aims to be lightweight, comfortable and sustainable. Theory about comfort in seats, ergonomics, lightweight design, Biomimicry and Cradle to cradle was studied and resulted in a list of requirements that the new seat should satisfy. The design process resulted in a new seat that is 36% lighter than the reference seat, which showed that a significant weight reduction can be achieved. This was completed by re-designing the backrest and seat pan and integrating their functions into a reduced number of parts. Apart from the weight reduction that helps in reducing the airplane's environmental impact, the seat also satisfies most of the other sustainability requirements such as the use of recyclable materials, design for disassembly, easy to repair. A user test compared the new seat with a premium economy class aircraft seat and the level of comfort was similar. Strong points of the new design were identified such as the lumbar support and the cushioning material, as well as shortcomings on which the seat needs to be improved, like the seat pan length and the first impression. Long term comfort tests are still needed as the seat is meant for long-haul flights.

  6. Living labs design and assessment of sustainable living

    Guerra-Santin, Olivia; Lockton, Dan

    2017-01-01

    This book presents the results of a multi-annual project with sustainable Living Labs in the United Kingdom, Sweden, Germany and the Netherlands. Living Labs – as initiated by the authors – have proved to be very promising research, design, co-creation and communication facilities for the development and implementation of sustainable innovations in the home. The book provides an inspiring introduction to both the methodology and business modelling for the Living Lab facilities. Understanding daily living at home is key to designing products and services that support households in their transition to more sustainable lifestyles. This book not only explores new ways of gaining insights into daily practices, but also discusses developing and testing design methods to create sustainable solutions for households. These new methods and tools are needed because those available are either ineffective or cause rebound-effects. Intended for researchers and designers with an interest in the transition to sustainable...

  7. Sustained oscillations in living cells

    Science.gov (United States)

    Danø, Sune; Sørensen, Preben Graae; Hynne, Finn

    1999-11-01

    Glycolytic oscillations in yeast have been studied for many years simply by adding a glucose pulse to a suspension of cells and measuring the resulting transient oscillations of NADH. Here we show, using a suspension of yeast cells, that living cells can be kept in a well defined oscillating state indefinitely when starved cells, glucose and cyanide are pumped into a cuvette with outflow of surplus liquid. Our results show that the transitions between stationary and oscillatory behaviour are uniquely described mathematically by the Hopf bifurcation. This result characterizes the dynamical properties close to the transition point. Our perturbation experiments show that the cells remain strongly coupled very close to the transition. Therefore, the transition takes place in each of the cells and is not a desynchronization phenomenon. With these two observations, a study of the kinetic details of glycolysis, as it actually takes place in a living cell, is possible using experiments designed in the framework of nonlinear dynamics. Acetaldehyde is known to synchronize the oscillations. Our results show that glucose is another messenger substance, as long as the glucose transporter is not saturated.

    2012-01-01

    In this article we examine aspects of the different arguments for the environmental advantages of co-housing compared with individual households. The analysis is structured around four main questions, which are argued to be decisive for the question of co-housing and sustainability. The first...... is whether co-housing offers better opportunities for choosing and using more sustainable technologies, which also relates to the question of whether co-housing offers better opportunities for building smaller and denser and thus more energy efficient buildings. The second and third questions are socially...... oriented; one relates to the claim that co-housing can support pro-environmental behaviour among residents as they can support each other’s norms and practices. The fourth and last claim relates to a discussion of co-housing as a more sustainable opportunity especially for people living alone...

    2009-12-01

    Full Text Available This paper provides a critical review of sustainability, including its definitions, dimensions, measurements, and practices, as well as approaches to achieve sustainability. It raises questions about conventional definitions and argues for taking into account the geographic dimension of sustainability for better understanding of the regional differences in sustainability and transition to sustainability. The paper proposes that sustainability should be defined as "living within one’s own ecological means." This definition pays attention to regional disparities in biocapacity and ecological footprint. It realizes that not all people’s present and future needs may be met in all regions of the world.

    2017-10-01

    Consumers are increasingly demanding the interior of cars to be comfortable even in the case of more economic commercial segments. Thus, the development of materials with thermoregulation properties has assumed renewed interest for these particular applications. An attempt has been made to prepare a multilayer PVC-based synthetic leather with paraffinic PCMs to be applied on a car seat. The thermal behaviour of the material was analysed using Alambeta apparatus, a thermo-camera and a thermal manikin. The results obtained show that the synthetic leather with incorporated PCMs gives cooler feeling and has higher reaction times regarding environmental temperature variations than the material without PCMs incorporation. Globally, the new designed material allowed greater thermal comfort to the cars´ inhabitants. In addition, the material quality was evaluated according to the standard of the customer, BMW 9,210,275; Edition / Version 4, 2010-10-01 revealing that the material meets all the requirements under test, except for the performance in terms of flexibility.

  13. Interrupting separateness, disrupting comfort: An autoethnographic account of lived religion, ubuntu and spatial justice

    Directory of Open Access Journals (Sweden)

    John Eliastam

    2016-02-01

    Full Text Available This article uses a fictionalised encounter as the basis for an autoethnographic exploration of the intersections between the South African social value of ubuntu and the notion of spatial justice. Ubuntu describes the interconnectedness of human lives. It asserts that a person is only a person through other people, a recognition that calls for deep respect, empathy and kindness. Ubuntu is expressed in selfless generosity and sharing. The spatial turn in the social sciences and humanities has resulted in a concern with the relationship between space and justice. It recognises that space is not simply an empty container in which people live and act, but is something that is constructed by social relations – and simultaneously constitutive of them. While this recognition gives rise to spatial perspectives on justice, what constitutes spatial, justice, as distinct from other notions of justice, and how such justice is to be achieved are contested. Building on the work of legal scholar, Andreas Philippopoulos-Mihalopoulos, on spatial justice, I argue that the notion of ubuntu is able to shape our understanding of spatial justice, and when practised, it is able to disrupt space and challenge dominant spatial configurations.

    Full Text Available An emerging concept in accommodations in the travel industry called Shared Living is blurring the lines between hospitality and residential living and is moving the industry towards greater ecological and social sustainability. Changing trends brought about by the sustainability challenge, climate change, technological advancements and increasing affluence and cultural awareness are disrupting the tourism industry. Meeting clients’ needs for Leisure and Relaxation is not enough. Increasingly sustainability-conscious travelers expect their fundamental needs of Participation, Creation and Identity to be fulfilled as well. Today’s travelers want to do more than eat, sleep and sightsee – they want to interact with the local communities they are visiting. But traditional accommodations offer little opportunity for travelers to engage with fellow travelers or local communities. Emerging trends in accommodations are increasingly connecting travelers to the people, organizations and projects that are changing lives and transforming communities. By understanding and adapting to the trends, the tourism industry can both contribute towards ecological social sustainability and reap the business benefits presented by the sustainability challenge of our time.

  18. The Experientiality of Sustainability: Living with Our Choices

    2015-12-01

    In an age when the escalating impact of human activity on the global environment has begun to threaten the long-term survival of humanity, increasing focus is being brought to bear on the scientific, social, economic, political, and cultural ramifications of the various courses of action open to individuals and societies across the globe. The intentional and intelligent modification of human behavior to balance environmental impact with human wellbeing is seen as the key to entering what Jeffrey Sachs has called the 'Age of Sustainable Development'. There are mechanisms, legal, socio-cultural, religious, economic, and technological that may ameliorate to varying degrees the environmental impact of human activity. These mechanisms are explored at length in the literature and assessed by their capacity to encourage or compel compliant behavior. They rely heavily on individual and collective choices based on rational self-interest, which is in turn informed by knowledge. The role of education in facilitating sustainable human activity is a key feature of many contributions to the literature. The alarming shortcoming in these discussions is the absence of an effective approach to learned sustainability that may achieve the necessary changes in human behavior and particularly adult choices with respect to daily acts of consumption. Sustainable practices and choices are most effectively produced through immersion in experientially based learning programs aimed at elementary and secondary school students. The experience of sustainable living during the critical phase of personal identity formation is the key to shaping behavior, and not just imparting knowledge. This AGU education session, ED041: Teaching Sustainability and Human Impact through Collaborative Teaching Methods, explores the principles on which such experiential immersion learning contributes to genuine sustainable behaviors and choices through targeted, intelligently designed residential programs.

    Full Text Available Finland aims to be a carbon-neutral society by the year 2050. We are interested to know on a general level how sustainable living materializes among Finnish people, what is the structure of a sustainable lifestyle in Finland and how do people reason about their everyday behavior choices in the context of sustainability in order to combat climate change. The data (n = 2052 were collected by questionnaire in April 2017. They were corrected by sex, age and residential area to be representative of the population of Finland (18–79 years old. We applied mixed methods. A principal axis factoring was conducted on the 32 variables with orthogonal rotation (varimax. Six factors explained 65.2% of the variance. The respondents were also able to write why they considered the specific variable to be important for them. We classified 2811 reasonings. According to our results, Finns have become conscious of climate change, but carbon reduction has not become mainstream in their everyday life. Circulation and preventing loss of materials show a promising start to a Finn’s sustainable way of living. Recycling has been automated so that it is part of a Finn’s everyday routine and habits. Finns also favor domestic food and products. They are interested in the origin of materials. Essential reasons for that are supporting the local economy and ensuring a good employment rate for the state. Smart, carbon-free mobility is a challenge. Finns seem to estimate that their personal car use is already at the proper level. On the other hand, even one fifth reported consideration of environmental effects when planning holidays.

  20. Comfort measures: a concept analysis.

    Science.gov (United States)

    Oliveira, Irene

    2013-01-01

    Reference to the concept of comfort measures is growing in the nursing and medical literature; however, the concept of comfort measures is rarely defined. For the comfort work of nurses to be recognized, nurses must be able to identify and delineate the key attributes of comfort measures. A concept analysis using Rodgers' evolutionary method (2000) was undertaken with the goal of identifying the core attributes of comfort measures and thereby clarifying this concept. Health care literature was accessed from the CINAHL and PubMed databases. No restrictions were placed on publication dates. Four main themes of attributes for comfort measures were identified during the analysis. Comfort measures involve an active, strategic process including elements of "stepping in" and "stepping back," are both simple and complex, move from a physical to a holistic perspective and are a part of supportive care. The antecedents to comfort measures are comfort needs and the most common consequence of comfort measures is enhanced comfort. Although the concept of comfort measures is often associated with end-of-life care, this analysis suggests that comfort measures are appropriate for nursing care in all settings and should be increasingly considered in the clinical management of patients who are living with multiple, chronic comorbidities.

  1. Documenting Living Monuments in Indonesia: Methodology for Sustainable Utility

    2013-07-01

    The systematic documentation of cultural heritage in Indonesia has been developed after the establishment of Bataviaasch Genootschap van Kunsten en Wetenschappen (1778) and De Oudheidkundige Dienst (1913) by the Netherlands Indies government. After Indonesian independent, the tasks of cultural heritage documentation take over by The Ministry of Culture (now become The Ministry of Education of Culture) with focus on the ancient and classical heritage, so called dead monument. The needed of comprehensive documentation data regarding cultural heritage become significant issues since the government and private sector pay attention to the preservation of heritage building in the urban site, so called living monument. The archives of original drawing plan many times do not fit with the existing condition, while the conservation plan demands a document such as built drawing plan to work on. The technology, methodology and system to provide such comprehensive document of heritage building and site become important, to produce good conservation plan and heritage building regular maintenance. It means the products will have a sustainable and various utility values. Since 1994, Documentation Centre for Architecture - Indonesia (PDA), has established to meet the needs of a comprehensive data of heritage building (living monuments), to utilized as basic document for conservation planning. Not only provide document of the digital drawing such site plan, plan, elevation, section and details of architecture elements, but also document of historic research, material analysis and completed with diagnosis and mapping of building damages.

    Many of the milestones of human development can be traced back to people assembled in groups where economies of scale, competition and social interaction stimulated innovation. Considering that more than half the global pollution now lives in cities and towns and that most of the growth in the global pollution in the remainder of this century will continue to take place in the urban environment, the question could be asked whether humankind will continue to capitalize on the traditional benefits of city life to find solutions for growing environmental challenges? By ensuring that cities are planned and operated to make best use of the prevailing climate, resources and in a manner in which its inhabitants are safe from extreme weather and environmental events there is a good chance that cities will continue to contribute to solutions. However, if cities are allowed to developed in a haphazard manner with poorly managed infrastructure which expose citizens to the dangers of a changing climate and environmental degradation, the fight for survival will overshadow the entrepreneurial spirit. There is now a window of opportunity for weather, climate, water and environmental scientists to contribute towards a more sustainable urban future by ensuring that services based on these sciences from an integrated part of urban development and management. WMO recognizes that the rapid urbanization will require new types of services making best use of science and technology and considers this problem as one of the main priorities. Such Integrated Urban Weather, Environment and Climate Services should assist cities in facing hazards such as storm surge, flooding, heat waves, and air pollution episodes, especially in changing climates. The talk will highlight some of the opportunities that exist in this regard.

    Comfort on automobile seats is lived daily by thousands of drivers. Epistemologically, comfort can be understood under the theory of complexity, since it emerges from a chain of interrelationships between man and several elements of the system. This interaction process can engender extreme comfort associated to the feeling of pleasure and wellbeing or, on the other hand, lead to discomfort, normally followed by pain. This article has for purpose the development of a theoretical model that favours the comfort feature on automobile seats through the identification of its facets and indicators. For such, a theoretical study is resorted to, allowing the mapping of elements that constitute the model. The results present a comfort model on automobile seats that contemplates the (physical, psychological, object, context and environment) facets. This model is expected to contribute with the automobile industry for the development of improvements of the ergonomic project of seats to increase the comfort noticed by the users.

    The Tiwi people of northern Australia have managed natural resources continuously for 6000-8000 years. Tiwi management objectives and outcomes may reflect how they gather information about the environment. We qualitatively analyzed Tiwi documents and management techniques to examine the relation between the social and physical environment of decision makers and their decision-making strategies. We hypothesized that principles of bounded rationality, namely, the use of efficient rules to navigate complex decision problems, explain how Tiwi managers use simple decision strategies (i.e., heuristics) to make robust decisions. Tiwi natural resource managers reduced complexity in decision making through a process that gathers incomplete and uncertain information to quickly guide decisions toward effective outcomes. They used management feedback to validate decisions through an information loop that resulted in long-term sustainability of environmental use. We examined the Tiwi decision-making processes relative to management of barramundi (Lates calcarifer) fisheries and contrasted their management with the state government's management of barramundi. Decisions that enhanced the status of individual people and their attainment of aspiration levels resulted in reliable resource availability for Tiwi consumers. Different decision processes adopted by the state for management of barramundi may not secure similarly sustainable outcomes. ©2012 Society for Conservation Biology.

    The current limitations of nitric oxide (NO) delivery systems have stimulated an extraordinary interest in the development of compounds that generate NO in a controlled and sustained manner with a heavy emphasis on the treatment of cardiovascular disease states. This work describes the positive physiological response to the infusion of NO-releasing nanoparticles prepared using a new platform based on hydrogel/glass hybrid nanoparticles. When exposed to moisture, these nanoparticles slowly release therapeutic levels of NO, previously generated through thermal reduction of nitrite to NO trapped within the dry particles. The controlled and sustained release of NO observed from these nanoparticles (NO-np) is regulated by its hydration over extended periods of time. In a dose-dependent manner, circulating NO-np both decreased mean arterial blood pressure and increased exhaled concentrations of NO over a period of several hours. Circulating NO-np induced vasodilatation and increased microvascular perfusion during their several hour circulation lifetime. Control nanoparticles (control-np; without nitrite) did not induce changes in arterial pressure, although a decrease in the number of capillaries perfused and an increase in leukocyte rolling and immobilization in the microcirculation were observed. The NO released by the NO-np prevents the inflammatory response observed after infusion of control-np. These data suggest that NO release from NO-np is advantageous relative to other NO-releasing compounds, because it does not depend on chemical decomposition or enzymatic catalysis; it is only determined by the rate of hydration. Based on the observed physiological properties, NO-np has clear potential as a therapeutic agent and as a research tool to increase our understanding of NO signaling mechanisms within the vasculature.

  1. Utilization of Live Localized Weather Information for Sustainable Agriculture

    2010-09-01

    Authors: Jim Anderson VP, Global Network and Business Development WeatherBug® Professional Jeremy Usher Managing Director, Europe WeatherBug® Professional Localized, real-time weather information is vital for day-to-day agronomic management of all crops. The challenge for agriculture is twofold in that local and timely weather data is not often available for producers and farmers, and it is not integrated into decision-support tools they require. Many of the traditional sources of weather information are not sufficient for agricultural applications because of the long distances between weather stations, meaning the data is not always applicable for on-farm decision making processes. The second constraint with traditional weather information is the timeliness of the data. Most delivery systems are designed on a one-hour time step, whereas many decisions in agriculture are based on minute-by-minute weather conditions. This is especially true for decisions surrounding chemical and fertilizer application and frost events. This presentation will outline how the creation of an agricultural mesonet (weather network) can enable producers and farmers with live, local weather information from weather stations installed in farm/field locations. The live weather information collected from each weather station is integrated into a web-enabled decision support tool, supporting numerous on-farm agronomic activities such as pest management, or dealing with heavy rainfall and frost events. Agronomic models can be used to assess the potential of disease pressure, enhance the farmer's abilities to time pesticide applications, or assess conditions contributing to yield and quality fluctuations. Farmers and industry stakeholders may also view quality-assured historical weather variables at any location. This serves as a record-management tool for viewing previously uncharted agronomic weather events in graph or table form. This set of weather tools is unique and provides a

    Full Text Available This article describes a first step towards a strategy for using living labs as a means to foster innovation and develop new concepts of sustainable living from an architectural point of view. The overall aim is to enable truly sustainable living through radically reduced energy and resource use thus addressing both environmental and social aspects of sustainability. Earlier research has shown that contemporary housing developments, including those with a sustainable profile, do not profoundly question modern lifestyles and consumption, which is a necessity to overcome limitations of a technological focus on environmental efficiency in construction. Thus, we see an opportunity for the discipline of architecture to engage in current investments in living lab facilities in order to push innovation in the field of sustainable housing. We introduce the concept of a "Habitation Lab", which will provide an arena for radical and high-risk design experimentation between users, building-sector actors, and academia, and we describe a case study of a planned Habitation Lab within a living lab facility where traditional solutions for daily living and habitation are questioned and new architectural innovations are explored and evaluated. The idea of using experimental activities in the field of housing is not new, and we argue that new investments should build on earlier experiences to avoid perpetuating misconceptions and repeating past failures. Furthermore, to ensure the dissemination and uptake of results, the design of the Habitation Lab should consider the innovation and learning trajectories of the building sector. We propose a transdisciplinary setting to provide a neutral arena for value creation and to increase the distribution of experiences.

    Tobacco has been associated with worse HIV disease progression in adult samples of people living with HIV; however, studies have yet to examine these effects in youth living with HIV (YLWH). This study examined the association between tobacco smoking behaviors and sustained viral suppression among a sample of 820 YLWH who were recruited through the Adolescent Medicine Trials Network for HIV Interventions. Participants completed a cross-sectional survey and then staff abstracted viral suppression data from medical records for up to 26 weeks prior to enrollment. Overall, 20.4% of youth reported daily or almost daily tobacco use. In multivariable analyses, older age and daily or almost daily tobacco smoking, and ART adherence remained statistically significant in predicting sustained viral suppression over the study period. These findings underscore the need for tobacco screening and interventions in HIV care settings in order to identify youth in need of additional smoking cessation services.

    In this article we examine aspects of the different arguments for the environmental advantages of co-housing compared with individual households. The analysis is structured around four main questions, which are argued to be decisive for the question of co-housing and sustainability. The first...... is whether co-housing offers better opportunities for choosing and using more sustainable technologies, which also relates to the question of whether co-housing offers better opportunities for building smaller and denser and thus more energy efficient buildings. The second and third questions are socially...... oriented; one relates to the claim that co-housing can support pro-environmental behaviour among residents as they can support each other's norms and practices. The fourth and last claim relates to a discussion of co-housing as a more sustainable opportunity especially for people living alone...

    Evaluations recognize healthy living champions (HLCs) as key contributors to the Health Living Pharmacy (HLP) project's success; the project has served to reduce pressure on family doctor services and clients who would have otherwise not sought professional advice have accessed HLP services. To investigate the impact of innovative networking opportunities in supporting HLCs to function within their role and to explore the network's potential in promoting sustained HLP participation. Twenty of Portsmouth's (England) HLCs (n = 33) agreed to participate in focus groups. Transcripts were subjected to interpretative phenomenological analysis guided by grounded theory. The transcripts were read repeatedly; recurrent themes were identified and coded manually and consensus was reached by discussion within the research team. Network meetings provide HLCs with professional development, networking opportunities and continued encouragement. Recommendations to develop and sustain the network included the formation of a group committee and establishing of a communication facility accessible between meetings. The successful Portsmouth HLP project informed the design of UK HLP projects. The current focus is to build a successful strategy to sustain the positive outcomes, building on the recognized enablers. This study contributes further lessons learned to guide health commissioners and service implementers to best support staff development, involvement and motivation through innovative practice.

    The post-2015 development agenda is dominated by a set of Sustainable Development Goals (SDGs) that arose from the 2012 Rio+20 United Nations Conference on Sustainable Development. The 17 goals and 169 targets address diverse and intersecting aspects of human and environmental needs and challenges. Achieving the SDGs by 2030 requires implementing coordinated and concerted strategies and actions that minimize potential trade-offs and conflicts and maximize synergies to contribute to multiple SDGs. Measures to mitigate emissions of short-lived climate pollutants are an example of actions that contribute to multiple outcomes relevant to development. This Perspective highlights the interlinkages between these pollutants and the SDGs, and shows that implementing emissions reduction measures can contribute to achieving many of the SDGs.

    2012-02-01

    Comfort is an important concept and core value of nursing. The defining attributes, antecedents and consequences of comfort need further analysis and exploration, even though the concept of comfort has been addressed previously in nursing literature. We employed the strategies of concept analysis as described by Walker&Avant (2005) to analyze the concept of comfort. The defining attributes of comfort include: 1) effective communication; 2) family and meaningful relationships; 3) maintaining functionality; 4) self-characteristics; 5) physical symptom relief, states, and interventions; 6) psychological, spiritual activities and states; and 7) a sense of safety and security. Antecedents consist of discomfort, distress and suffering. Consequences consist of (1) met/satisfied needs; (2) increased sense of control; (3) sense of inner peace; (4) a pleasant experience; (5) feeling cared for; (6) relief of symptoms; (7) reduced suffering; (8) decreased disequilibrium; and (9) absence of discomfort. We also outline the construction of cases, empirical references and comfort measurement tools. Analysis found comfort to have multiple dimensions and confirmed it as a clinical issue that should receive greater emphasis and valuation. Findings are hoped to increase nurse understanding of the concept of comfort and enable nurses to evaluate level of comfort and follow up on variations in such using empirical tools. Concept analysis can guide further comfort related interventions and research to benefit patients.

Data were collected from 88 caregivers of cancer patients using the Caregiver General Comfort Questionnaire (GCQ to assess the caregivers’ comfort. The caregivers’ GCQ score mean was 203.9; better comfort scores was associated with age, care time and current occupation; positive aspects of comfort were related to the fact that caregivers felt loved, to patients’ physical and environmental comfort and to caregivers’ spirituality. 203.9; better comfort scores were associated with age of the caregiver and current occupation; positive aspects of comfort were related to the fact that caregivers felt loved, to patients’ physical and environmental comfort and to caregivers’ spirituality. Caregivers, who didn’t have a paid job or leisure’s activities showed a worse GCQ. The GCQ scale can help to identify factors that interfere in caregivers’ comfort, as well as needs that can be modified through health professionals’ interventions.

    2014-04-01

    Full Text Available Normal 0 false false false EN-US X-NONE X-NONE The greatest challenge of future development of urban areas has been related with the sustainability issues. Unfortunately, sustainability issues and related costs of resources, including energy, occupy minds only of minority in the society. In the process of transition toward low carbon society many countries have set indicative targets which are revealing desired momentum of change but only at the national level. The absence of clear and direct transformation of national targets into implementation programmes at the local level was the crucial reason why many previous goals have not been achieved. Within the paper, six main sustainability indicators related to the quality of living in urban areas have been described and discussed. Indicators have been tested and customised during the analysis of future development challenges of the Slovenian capital, City of Ljubljana. Results of the analysis show that suggested indicators may be used in the process of municipal energy planning. During the research work, technology and sector oriented bottom up reference energy and environmental system model of City of Ljubljana has been developed. It is the first so complex reference energy and environmental system model that has been developed on the municipal level in the Southeast Europe.

  18. Biological sustainability of live shearing of vicuña in Peru.

    2007-02-01

    The vicuña's (Vicugna vicugna) fiber is highly valued as an export product that is made into luxury fabric and clothing. The price of fiber in 2004 was 566/kg dollars, which makes the fiber a potentially important source of income for Andean agropastoral communities and serves as an incentive to allow vicuña grazing on high-elevation Andean landscapes. It is presumed that a shorn vicuña has little value for poachers, so shearing vicuñas could serve as a disincentive to poaching. Thus, the supply of vicuña fiber may be sustainable if it is procured through live shearing, which should serve as a powerful conservation tool. We evaluated the effects of capture and shearing on the demography of vicuña in one site located in the Salinas Aguada Blanca Reserve, Arequipa, Peru, where vicuñas were captured and shorn in spring and then returned to the wild. We conducted fixed-width line-transect censuses from 1997 to 2003 of this population. We compared the proportion of young born to females that were shorn versus females that were unshorn for the 3 years in which shearing occurred. We evaluated the effect of capture and shearing on proportion of young born to shorn and unshorn females at a second site, Picotani, Puno. The wild population in Arequipa that underwent capture and shearing showed a steady increase in total population and average density between 1997 and 2003. No significant difference was found between the proportion of young per female for shorn and unshorn females at either site. We conclude that in spring, capture and live shearing of vicuñas can be biologically sustainable. Further research is needed to determine whether shearing during winter months is biologically sustainable.

    Traditional, pre-industrial farming was adapted to the natural environment-topography, geology, hydrology, climate, and biota. Traditional land use systems are still to be traced in Scandinavia as an "infield/outland landscape", and in Japan as a "Satoyama landscape." There are obvious similarities and differences in land use-the main difference being that pasturing of cattle and sheep has been less important in Japan. These land use systems can be traced back to early sedentary settlements 1500-2500 years ago. In both regions, traditional management almost ceased in the mid-twentieth century leading to afforestation and decreased biological diversity. Today, there is in Japan a growing movement for landscape restoration and promotion of a sustainable living countryside based on local agrarian and forestry production, local energy, tourism, etc. With this background, the so-called Satoyama Initiative has been organized and introduced as a global socio-ecological project with ecosystem services for human well-being.

  1. Estimating Sustainable Live-Coral Harvest at Kamiali Wildlife Management Area, Papua New Guinea.

    Ken Longenecker

    Full Text Available Live coral is harvested throughout the Indo-West Pacific to make lime, used in the consumption of the world's fourth-most consumed drug, betel nut. Coral harvesting is an environmental concern; however, because lime-making is one of the few sources of income in some areas of Papua New Guinea (PNG, the practice is unlikely to stop. To better manage coral harvest, we used standard fishery-yield methods to generate sustainable-harvest guidelines for corymbose Acropora species found on the reef flat and crest at Lababia, PNG. We constructed a yield curve (weight-specific net annual-dry-weight production by: 1 describing the allometric relationship between colony size and dry weight, and using that relationship to estimate the dry weight of Acropora colonies in situ; 2 estimating annual growth of Acropora colonies by estimating in situ, and describing the relationship between, colony dry weight at the beginning and end of one year; and 3 conducting belt-transect surveys to describe weight-frequencies and ultimately to predict annual weight change per square meter for each weight class. Reef habitat covers a total 2,467,550 m2 at Lababia and produces an estimated 248,397 kg/y (dry weight of corymbose Acropora, of which 203,897 kg is produced on the reef flat/crest. We conservatively estimate that 30,706.6 kg of whole, dry, corymbose, Acropora can be sustainably harvested from the reef flat/crest habitat each year provided each culled colony weighs at least 1805 g when dry (or is at least 46 cm along its major axis. Artisanal lime-makers convert 24.8% of whole-colony weight into marketable lime, thus we estimate 7615.2 g of lime can be sustainably produced annually from corymbose Acropora. This value incorporates several safety margins, and should lead to proper management of live coral harvest. Importantly, the guideline recognizes village rights to exploit its marine resources, is consistent with village needs for income, and balances an equally

    We connect modern, intensive agriculture’s role in environmental degradation to its role in producing nutritionally unbalanced foods, and delineate specific approaches to reduce agriculture’s environmental impact, while producing healthful foods. We call attention to recently discovered genetic programs used by all living organisms to respond to their environment, and present a model of how these programs change body composition and function (of humans and their crop plants and livestock alike) in response to environmental cues. We propose that production of nutritionally balanced crops and livestock requires careful consideration of how these plants and animals are grown; the composition of plant food is modulated by growing conditions, body composition of livestock reflects their feed; composition and function of human body and brain are strongly affected by how food plants and animals are produced. We selected four nutritional features not only involved in (i) governing human health by modulating these genetic programs, but (ii) also affected by agricultural practices. These nutritional features are fat composition (especially saturated fat and the ratio of polyunsaturated omega-6 oils to omega-3 oils), carbohydrate composition (especially the proportion of carbohydrates with a high glycemic index, such as sugars and quick-burning starches) and the level of antioxidant micronutrients. We not only outline threats to human health presented by the current environment, but also potential gains in quality-of-life in a future environment designed to optimize human wellness using insights into the gene-programing effect of diet- and other lifestyle-related factors. These gains could extend beyond optimal human physical and mental health to gains in workforce productivity. The same changes in agricultural practices required to achieve these gains in human health are also needed to support environmental health and sustainable food production. The resulting vision of

We not only outline threats to human health presented by the current environment, but also potential gains in quality-of-life in a future environment designed to optimize human wellness using insights into the gene-programming effect of diet- and other lifestyle-related factors. These gains could extend beyond optimal human physical and mental health to gains in workforce productivity. The same changes in agricultural practices required to achieve these gains in human health are also needed to support environmental health and sustainable food production. The

    Ahrentzen, Sherry

    2008-06-01

    Greendale, Wisconsin, was intentionally created with many of the design and planning principles that active-living advocates promote today. This case study examines the processes behind sustaining these particular planning and design principles over time in light of economic and regional challenges that have faced not just Greendale but most town centers over the last fifty years. Despite these challenges, the walkable nature of Greendale's center remains strong today, in terms of both activity and community identity. While many circumstances are specific to this particular town, useful lessons can be drawn for those new urbanist (NU) communities being developed in greenfields and suburbs today, many of which are strikingly similar to Greendale - relatively small, low density, and located within metropolitan areas. Greendale's success resulted from (1) attending to the retail/commercial product mix; (2) attracting nonresidents to use the community's retail and public space; and (3) capitalizing on community investment not simply from residents' organizing efforts but, more important in this case, from corporate community involvement by a Greendale business firm whose interests and values coincided with those of the community.

    The development of new methods of administering coccidiosis vaccines has facilitated their use in the hatchery and thereby improved prospects for the economic vaccination of broilers. The acquisition of protective immunity to Eimeria species is boosted by further exposure to infection after vaccination. Factors that affect the reproductive efficiency of non-attenuated and attenuated vaccines are considered and the key role that oocyst production plays in establishing and maintaining uniform immunity in a flock of chickens is discussed. In addition to immunisation, a possible advantage to the application of certain vaccines is that their use could repopulate poultry houses with drug-sensitive organisms. Theoretical rotation programmes in which the use of drugs is alternated with that of vaccines are described. Variability of the cross-protective immune response between strains of the same species should be considered during vaccine development and subsequent use. The significance of less common species of Eimeria, not included in all vaccines, also needs to be assessed. An important consideration is the occurrence of pathogens other than Eimeria (such as the bacterium Clostridium) in flocks given coccidiosis vaccines and the methods by which they might be controlled. More research is required into the relationship between bacterial and viral infections of poultry and coccidiosis vaccination. Vaccines need to be developed that are simple to apply and cost effective for use in areas of the world where small-scale poultry production is commonplace. In the near future it is likely that more live vaccines based upon oocysts derived from attenuated strains of Eimeria will be developed but in the longer term vaccines will be based on the selective presentation to the host of specific molecules that can induce protective immunity. This achievement will require significant investment from the private and public sectors, and, if successful, will facilitate the sustainable

    Critical thinking is skill and ability to use of risk taking creativity to make a decision and knowledge as a result, analysis and synthesis that, evaluation, to acquire, information search, to develop thinking, as an individual aware of his or her own thinking. The aim of this study is to develop the science virtual test to measure students’ critical thinking on living things and environmental sustainability theme. The research method that is used in this research was descriptive research. The development of science virtual test item consist of five steps: (1) content analysis; (2) constructing the instrument (multiple choice) based on the elements of critical thinking by Inch; (3) validity judgment of the instrument by the expert; (4) legibility test of the instrument; (5) conducting the large field test. On the large field test was gained the results of validity and reliability of the test, difficulty index, discriminating power, and quality of distractor. The subjects of research were 8th grade students at International Junior High School in Bandung with 125 total of respondents. The coefficient alpha (α) was 0.747, the reliability of the test was categorized as ‘high’ and value of RXY correlation was 0.63 which mean that the validity of the test was categorized as ‘high’. These means that science virtual test can be used to measure student’s critical thinking with a good consistency. It is expected for other researcher to take this description as one of the basic information to be considered in developing science virtual test for improving students’ critical thinking by various kind of topic.

    This work presents considerations on Ergonomics and Design for Sustainability in the healthcare field based on research experiences of the Technology and Design for Healthcare (TeDH) research group of INDACO (Industrial design, communication, arts and fashion) department of Politecnico di Milano. In order to develop a multidisciplinary approach to design able to answer to specific user needs such as elderly in an environmental sustainable way (1) this paper shows the results we achieved concerning ergonomics and environmental impact in product development (2), the extension of this approach to interior and home design and the advantage of the application of Information Communication Technologies (ICT). ICT can help people with special needs to make their everyday life easier and more safe, at the same time, ICT can make social-environmental impact of everyday behavior evident and can be applied to manage sustainability. The specific theme is thus to integrate ergonomics and sustainability competences in the development of Ambient Assisted Living through a Product- Service System approach. The concept of product service system has the potential to improve product performances and services, establish new relations and networks with different actors in order to satisfy user needs and apply a systems approach considering environmental, social and economic factors in the users' environment.

  19. Sustainable Urban Development and Social Sustainability in the Urban Context

    Directory of Open Access Journals (Sweden)

    Faruq Ibnul Haqi

    2016-08-01

    Full Text Available Social sustainability and sustainable urban developments are major challenges across the world both developed and developing countries. In general there is a conflict between the approach of sustainable development and social sustainability in the urban context. The concept of sustainability brings a key framework for extensive literature on urban design, architecture and planning. Nevertheless there is a considerable overlap between the social dimensions of sustainability and the theories or notions, for instance the ‘sustainable societies’ that are highlighted in the midst of other aspects: social equity and justice. Such society is widely expected to offer a situation for long-term social relations and activities which are sustainable, inclusive and equitable in a wider perception of the term (environmentally, socially and economically. The method adopted to address this aim involves a content analysis of available academic literature, with focus on the planning sustainable development, built environment, social sustainability, and urban planning fields. The findings demonstrate that in spite of some opposing evidence, many studies have confirmed that there has been displacement of the debate on the term of ‘sustainability’ from ‘ecological and environmental aspects into social and economic aspects’. It is related to how the community feel safe and comfortable living in their own communities, how have they felt of proud of the place where they live. The aim of the paper is to improve our understanding of current theories and practices of planning sustainable development and discuss whether the approach of sustainable development aligns with social sustainability objectives.

    People seek out their own idiosyncratic comfort foods when in negative moods, and they believe that these foods rapidly improve their mood. The purpose of these studies is to investigate whether comfort foods actually provide psychological benefits, and if so, whether they improve mood better than comparison foods or no food. Participants first completed an online questionnaire to indicate their comfort foods and a variety of comparison foods. During two lab sessions a week apart from each other (and at least a week after the online questionnaire, counterbalanced in order), participants watched films that induced negative affect. In one session, participants were then served their comfort food. In the other, participants were served an equally liked noncomfort food (Study 1), a neutral food (Study 2), or no food (Studies 3 and 4). Short-term mood changes were measured so that we could seek out psychological effects of these foods, rather than biochemical effects on mood from particular food components (e.g., sugars or vitamins). Comfort foods led to significant improvements in mood, but no more than other foods or no food. Although people believe that comfort foods provide them with mood benefits, comfort foods do not provide comfort beyond that of other foods (or no food). These results are likely not due to a floor effect because participants' moods did not return to baseline levels. Individuals may be giving comfort food "credit" for mood effects that would have occurred even in the absence of the comfort food.

    2017-05-01

    The idea that human well-being (WB) can be supported and even enhanced by using, producing, buying, selling and consuming less `stuff' is anathema to many living under consumer capitalism. Yet a growing research literature actually finds that frequent engagement in pro-ecological behaviours (PEBs) is positively correlated with personal WB. This paper reviews data relevant to three possible explanations for the apparent compatibility of PEBs and WB: (i) engaging in PEBs leads to psychological need satisfaction, which in turn causes WB; (ii) being in a good mood causes people to engage in more prosocial behaviours, including PEBs; and (iii) personal characteristics and lifestyles such as intrinsic values, mindfulness and voluntary simplicity cause both PEBs and WB. Because each explanation has some empirical support, I close by reflecting on some relevant interventions and policies that could strengthen each of these three pathways and thereby promote living both well and sustainably. This article is part of the themed issue 'Material demand reduction'.

    2010-12-01

    The emergence of sustainability as a goal in the management of fossil fuel resources is a result of the growing global environmental concern, and highlights some of the issues expected to be significant in coming years. In order to secure social acceptance, the mining industry has to face these challenges by engaging its many different stakeholders and examining their sustainability concerns. For this reason a questionnaire was conducted involving a simple random sampling of inhabitants near an area rich in fossil fuel resources, in order to gather respondents' views on social, economic and environmental benefits. The study discusses new subnational findings on public attitudes to regional sustainability, based on a quantitative research design. The site of the study was the energy-rich Greek region of Kozani, Western Macedonia, one of the country's energy hubs. The paper examines the future perspectives of the area. The conclusions can form a useful framework for energy policy in the wider Balkan area, which contains important fossil fuel resources. Copyright © 2010 Elsevier Ltd. All rights reserved.

    The presentation of the Company starts with having it ranked among the ones operating on the customers` market or those acting on the professional market. But it is not so. Honeywell is beyond such simple criteria. We are a company supplying products, systems and services related with generally conceived automatic control engineering, yet the operational range does comprise so many apparently diversified fields, for instance automatic control in aeronautics, heavy power engineering, building of apartment buildings, detached houses, heat engineering and some others. Nevertheless, our targets are always the same: maximum increase in efficiency and reliability of the process lines controlled by our systems as well as securing the best comfort of work and rest for people who stay in the buildings controlled by our devices. Simultaneously, the utilization of energy sources and the natural environment resources must be as sensible as possible.

  9. Hoof Comfort for Horses

    Science.gov (United States)

    2002-01-01

    Aquila Equine Enhancement Products, Inc., of Woburn, Massachusetts, developed magnetic hoof protector pads, called "Power Pads," which support and cushion the impact on a horse's hooves and legs to provide comfort and protection against injuries. The pads were tested by Marshall Space Flight Center's Materials and Processing Laboratory for strength and durability. Putting the pads on a horse does not interfere with its natural movement or flexibility and can be compared to a person changing into athletic shoes for a sporting event. The pads are cut to the appropriate size, and then mounted onto a horse's hooves using conventional shoeing methods. Once attached, the pads protect the hard and soft parts of the hoof by cushioning blows against the hard ground. The design also protects the vulnerable "heel" of the hoof. They are a cost-effective way to protect a horse's hooves since they can be reused.

    The Unilever Sustainable Living Plan will result in three significant outcomes by 2020: (1) help more than a billion people take action to improve their health and well-being; (2) decouple growth from the environmental impact of Unilever activities, achieving absolute reductions across the product lifecycle. Unilever's goal is to halve the environmental footprint of the making and use of products; and (3) enhance the livelihoods of hundreds of thousands of people in the supply chain. [Dutch] Unilever lanceerde zijn Sustainable Living Plan aan het eind van 2010. Dit plan is gericht op het verdubbelen van de groei van het bedrijf, waarbij het gebruik van water, afval en de emissie van broeikasgassen (BKG) halveert gedurende de levenscyclus van de producten. Productiebedrijven vertegenwoordigen slechts drie procent van de broeikasgas footprint, maar Unilever is daar direct verantwoordelijk voor. Voor de carbon footprint van de productie is daarom een uitgebreid implementatieplan ontwikkeld, met inbegrip van concepten voor nieuwe 'groene' fabrieken en productielijnen, productieprocesverbeteringen, het gebruik van hernieuwbare energie en verbeteringen in de bestaande fabrieken. Voor opwekking van koude en beperking van de uitstoot van broeikasgassen zijn tien verbeterpunten geidentificeerd, en is het besparingspotentieel gekwantificeerd.

    This study examines the effects of cultural factors on the evaluation of acoustic quality of residential areas, within the context of general environmental conditions. A comparative study was carried out between the UK and Taiwan, through questionnaire surveys at three stages, namely in selected residential areas, with respondents in their place of work/study, and using a web-based survey, respectively. This study reveals the importance of considering cultural factors, as well as their living experiences. This is reflected by the significant differences between the two cultures in a number of aspects, including choosing and evaluating living environment, noise noticeability, annoyance and sleep disturbance, activities, and sound preference. It is interesting to note the factor 'quiet' is an important consideration compared to other factors, in both the UK and Taiwan. Crown Copyright © 2013. Published by Elsevier B.V.

    Regulation of an intracellular acidic environment plays a pivotal role in biological processes and functions. However, spatiotemporal analysis of the acidification in complex tissues of living subjects persists as an important challenge. We developed a photo-inactivatable bioluminescent indicator, based on a combination of luciferase-fragment complementation and a photoreaction of a light, oxygen, and voltage domain from Avena sativa Phototropin1 (LOV2), to visualize temporally dynamic acidification in living tissue samples. Bioluminescence of the indicator diminished upon light irradiation and it recovered gradually in the dark state thereafter. The recovery rate was remarkably sensitive to pH changes but unsusceptible to fluctuation of luciferin or ATP concentrations. Bioluminescence imaging, taken as an index of the recovery rates, enabled long-time recording of acidification in apoptotic and autophagous processes in a cell population and an ischemic condition in living mice. This technology using the indicator is widely applicable to sense organelle-specific acidic changes in target biological tissues. PMID:23690604

    2012-01-01

    Both the UN (2007) and World Health Organizations (2004) have declared the enormous social and economic burden imposed on society by injuries due to road collisions as a major global problem. While the road safety problem is not new, this prominent global declaration sends an important signal of frustration regarding progress to date on reducing road collisions. It is clear that governments, communities, businesses and the public must discover ways of reducing this burden, especially as it relates to vulnerable road users (VRUs), typically meaning pedestrian and bicyclist road users. Recent comparisons of global VRU collisions statistics suggest that, in addition to mixed land use density, the layout of neighbourhood roads plays a vital role in the encouragement of walkable, safe and quiet, yet accessible and sustainable communities. The purpose of this paper was to: The Dutch Sustainable Road Safety (SRS) Program has produced a number of innovative land use and transportation initiatives for vehicular road users as well as non-vehicular VRUs. Following from the Dutch initiatives, these new 3-way offset, and fused grid neighbourhood patterns appear to not only have positive effects in encouraging mode split (i.e. increasing walking and bicycling, and transit), slowing traffic, and reducing energy consumption and GHG emissions; but also, to hold potential to improve road safety. To test the road safety hypothesis, UBCO researchers evaluated the level of road safety relative to five neighbourhood patterns - grid, culs-de-sac, and Dutch Sustainable Road Safety (SRS) (or limited access), 3-way offset, and fused grid networks. Analysis using standard transportation planning methodology revealed that they would maintain both mobility and accessibility. Analysis using standard road safety analysis methodology further revealed that these 3-way offset, and fused grid patterns would significantly improve road safety levels by as much as 60% compared to prevalent patterns (i

    The Chernobyl accident highlighted the need in nuclear preparedness for robust, effective and sustainable countermeasure strategies for restoration of radioactively contaminated residential areas. Under the EC-supporter STRATEGY project a series of investigations were made of countermeasures that were deemed potentially applicable for implementation in such events in European Member States. The findings are presented in this report, in a standardised data sheet format to clarify the features of the individual methods and facilitate intercomparison. The aspects of averted doses and management of wastes generated by countermeasures had to be described separately to provide room for the required level of detail. The information is mainly intended as a tool for decision makers and planners and constitutes of basis for the STRATEGY decision framework for remediation of contaminated urban areas. (au)

    Social media, with its capabilities of fast, global information sharing, provides a useful medium for professional development, connecting and collaborating with peers, and outreach. The goals of this study were to describe a new, sustainable model for Twitter use by professional societies, and analyze its impact on @AACAnatomy, the Twitter account of the American Association of Clinical Anatomists. Under supervision of an Association committee member, an anatomy graduate student developed a protocol for publishing daily tweets for @AACAnatomy. Five tweet categories were used: Research, Announcements, Replies, Engagement, and Community. Analytics from the 6-month pilot phase were used to assess the impact of the new model. @AACAnatomy had a steady average growth of 33 new followers per month, with less than 10% likely representing Association members. Research tweets, based on Clinical Anatomy articles with an abstract link, were the most shared, averaging 5,451 impressions, 31 link clicks, and nine #ClinAnat hashtag clicks per month. However, tweets from non-Research categories accounted for the highest impression and engagement metrics in four out of six months. For all tweet categories, monthly averages show consistent interaction of followers with the account. Daily tweet publication resulted in a 103% follower increase. An active Twitter account successfully facilitated regular engagement with @AACAnatomy followers and the promotion of clinical anatomy topics within a broad community. This Twitter model has the potential for implementation by other societies as a sustainable medium for outreach, networking, collaboration, and member engagement. Clin.

  3. Combining thermal comfort models

    1999-07-01

    Two models commonly used in thermal comfort studies were combined to develop a two-dimensional computer model that estimates the resistance to dry and evaporative heat transfer for a clothing system from fabric resistance data, fabric thickness data, and information concerning the amount of body surface area covered by different fabric layers and the amount of air trapped between fabric layers. Five different clothing ensembles with different total thermal insulation and very different distributions of the insulation on the body were simulated with 16 sedentary subjects. This paper first evaluates total thermal insulation predictions from the Fanger steady-state model and then uses these data in the Gagge two-compartment (or two-node) model. The combined model uses the transient heat balance of each segment and the whole body. It estimates total insulation value and then uses this value to calculate transient temperature and wettedness. By application of the combined model, predictions of human responses to a wide range of thermal conditions are compared with the responses of human subjects as described in reports of laboratory experiments. Possible reasons for discrepancies between the observed data and predictions of the model are briefly discussed.

Recent estimates of malaria-attributable under-five deaths prevented using the Lives Saved tool (LiST, extrapolating effectiveness estimates from community-randomized trials of scale-up of insecticide-treated nets (ITNs in the 1990s, confirm the substantial impact and good cost-effectiveness that ITNs have achieved in high-endemic sub-Saharan Africa.

    Palliative care aims to provide maximum comfort to the patient. However it is unknown what factors facilitate or hinder the experience of comfort, from the perspective of inpatients of palliative care units. This lack of knowledge hinders the development of comfort interventions adjusted to these patients. The aim of this research is to describe the comfort and discomfort experienced by inpatients at palliative care units. A phenomenological descriptive study was undertaken. Ten inpatients were recruited from a Spanish palliative care unit and seven from a Portuguese palliative care unit. Data were collected using individual interviews and analysed following the method of Giorgi. Four themes reflect the essence of the lived experience: The Palliative Care as a response to the patient's needs with advanced disease, attempt to naturalize advanced disease, confrontation with their own vulnerability, openness to the spiritual dimension. Informants revealed that they experience comfort through humanized care, differentiated environment, symptomatic control, hope and relationships. The discomfort emerges from the losses and powerlessness against their situation. Even if such findings may seem intuitive, documenting them is essential because it invites us to reflect on our convictions about what it means to be comfortable for these patients, and allows incorporating this information in the design of focused interventions to maximize the comfort experience.

    Cultural beliefs about and preferences for care at the end of life are diverse and unique in many respects. This descriptive qualitative study presents findings about the attitudes and preferences of people born in Japan, China, and Vietnam and living in the southern part of the USA regarding life-sustaining measures. In-depth personal and focus group interviews were conducted with 46 participants and thematic analysis completed. The findings reflected some similarities and differences among the three groups concerning initiation and discontinuance of artificial nutrition and mechanical ventilation. They also demonstrated the requirement for sensitivity to individual needs when honouring the wishes of patients and surrogate decision makers. Interventional studies should follow that test educational strategies to improve practice outcomes for health-care providers who care for these populations at this vulnerable time of life.

    Regulatory T cells (Tregs) expressing FOXP3 are essential for the maintenance of self-tolerance and are deficient in many common autoimmune diseases. Immune tolerance is maintained in part by IL-2 and deficiencies in the IL-2 pathway cause reduced Treg function and an increased risk of autoimmunity. Recent studies expanding Tregs in vivo with low-dose IL-2 achieved major clinical successes highlighting the potential to optimize this pleiotropic cytokine for inflammatory and autoimmune disease indications. Here we compare the clinically approved IL-2 molecule, Proleukin, with two engineered IL-2 molecules with long half-lives owing to their fusion in monovalent and bivalent stoichiometry to a non-FcRγ binding human IgG1. Using nonhuman primates, we demonstrate that single ultra-low doses of IL-2 fusion proteins induce a prolonged state of in vivo activation that increases Tregs for an extended period of time similar to multiple-dose Proleukin. One of the common pleiotropic effects of high dose IL-2 treatment, eosinophilia, is eliminated at doses of the IL-2 fusion proteins that greatly expand Tregs. The long half-lives of the IL-2 fusion proteins facilitated a detailed characterization of an IL-2 dose response driving Treg expansion that correlates with increasingly sustained, suprathreshold pSTAT5a induction and subsequent sustained increases in the expression of CD25, FOXP3 and Ki-67 with retention of Treg-specific epigenetic signatures at FOXP3 and CTLA4.

  9. Sustainable remote Australian transport for living on country and going out bush

    2017-06-01

    Full Text Available Both the domestic and international academic literature’s analysis of links between transport and wellbeing focuses mainly on urban settings and vulnerable population groups including older people, people with health issues, socio-economically disadvantaged people, or people undergoing more frequent extreme climatic events. While the relationship between remote Australians wellbeing and travelling activities is evident, its complexity still remains an under-researched topic. This is paradoxical when considering that extreme distances, high supply chain costs, limited access to services and to economic participation are well recognised obstacles for sustaining vibrant remote Australian communities. The latest accessibility-driven technological innovations in both the digital and the sharing economies are highly topical in transport projects in urban agglomerations but still a distant reality for remote Australia. There is a need for researching an appropriateness framework of such technologies because of the strong relevance of the multiple outcomes in terms of wellbeing that some of these innovations provide. Furthermore what defines a good quality of life can sometimes be very similar and other times greatly differ between remote and urban contexts. In the light of some recent transport and mobility research this paper analyses the potential connections between more appropriate transport innovations and increasingly resilient remote communities.

    2011-01-01

    This article investigates the evolution of sustainability positioning in residential property marketing to shed light on the specific role and responsibility of housebuilders and housing investors in urban development. To this end, an analysis is made of housing advertisements published in Basel, Switzerland, over a period of more than 100 years. The paper demonstrates how to draw successfully on advertisements to discern sustainability patterns in housing, using criteria situated along the dimensions building, location and people. Cluster analysis allows five clusters of sustainability positioning to be described—namely, good location, green building, comfort living, pre-sustainability and sustainability. Investor and builder types are differently located in these clusters. Location emerges as an issue which, to a large extent, is advertised independently from other sustainability issues.

  17. From occupying to inhabiting - a change in conceptualising comfort

    2009-11-01

    The concept of 'comfort' has been influential in shaping aspects of our built environment. For the construction industry, comfort is predominantly understood in terms of the balance between an ideal human physiological state and a finite number of measurable environmental parameters that can be controlled (temperature, humidity, air quality, daylighting, noise). It is such a notion of comfort that has informed the establishment of universally applied comfort standards and guidelines for the built environment. When buildings rigidly conform to these standards, they consume vast quantities of energy and are responsible for higher levels of GHG emissions. Recent researchers have challenged such instrumental definitions of comfort on moral and environmental grounds. In this paper, we address this issue from two different standpoints: one empirical, one related to the design of technology. Empirically, we present an analysis of ethnographic field material that has examined how, in what circumstances, and at what times ordinary users employ energy-intensive indoor climate technologies in their daily lives. We argue that when comfort is viewed as an achievement, rather than as a reified and static ideal homeostasis between humans and their environmental conditions, it becomes easier to appreciate the extent to which comfort is, for ordinary people, personally idiosyncratic, culturally relative, socially influenced and highly dependent on temporality, sequence and activity. With respect to design, we introduce a set of provocative designed prototypes that embody alternative conceptions of 'comfort' than those to which the building industry typically subscribes. Our discussion has critical implications for the types of technologies that result from a 'comfort standards' conception. Firstly, we show that comfort is not simply a homeostatic equilibrium-such a view is overly narrow, inflexible and ultimately an inaccurate conception of what comfort is for ordinary people

The factor of occupant comfort is the main element to indicate whether the housing is successful or not. In this writing, the thermal comfort discussed in only relating to the thermal comfort zone in Malaysia and the results from the study of the internal temperature of modern houses from previous researchers. Results by a few researchers found that modern houses are currently not reaching a good level of thermal comfort to live in and the designs are not capable to resolve the issue of discomfort in the internal environment of the houses in Malaysia. Therefore, thermal comfort is one of the important aspects of research in the development of modern housing because it plays a very important role in enhancing welfare, health and the quality of life or urban society.

    Formal living collections have unique characteristics that distinguish them from other types of biorepositories. Comprising diverse resources, microbe culture collections, crop and biodiversity plant germplasm collections, and animal germplasm repositories are commonly allied with specific research communities or stakeholder groups. Among living collections, microbial culture collections have very long and unique life histories, with some being older than 100 years. Regulatory, financial, and technical developments have impacted living collections in many ways. International treaty obligations and restrictions on release of genetically modified organisms complicate the activities of living collections. Funding for living collections is a continuing challenge and threatens to create a two-tier system where medically relevant collections are well funded and all other collections are underfunded and hence understaffed. Molecular, genetic, and whole genome sequence analysis of contents of microbes and other living resource collections bring additional value to living collections. PMID:27869477

    Full Text Available This paper presents the results of a survey among pre-service and inservice students of pre-school education and students of environmental sciences on the acceptability of value-laden statements made by their teachers on issues of sustainable development and climate change. Fifteen statements were provided, and students had to choose among the options »acceptable statement«, »unacceptable statement« and »cannot decide«. The questionnaire was completed by 139 students from two universities in Slovenia. The results show that the students expect their teachers to promote the principles of sustainable development. The majority of students considered any teacher’s statement that would cast doubt on the cause or the necessity to act against climate change to be unacceptable. Teacher’s statements emphasising global issues that have, or could have, a direct impact on developed countries (e.g. climate change received higher support than those global questions that more heavily impact underdeveloped or developing countries (e.g. poverty, child labour, access to natural resources. In the conclusion, it is emphasised that teachers should assist students in developing their own moralpositions on complex issues such as sustainable development and climate change. Structured discussion techniques, such as a panel discussion, forum and debate, should be regularly and carefully implemented into lectures at the university level.

    Birds may allocate a significant part of time to comfort behavior (e.g., preening, stretching, shaking, etc.) in order to eliminate parasites, maintain plumage integrity, and possibly reduce muscular ankylosis. Understanding the adaptive value of comfort behavior would benefit from knowledge on the energy costs animals are willing to pay to maintain it, particularly under situations of energy constraints, e.g., during fasting. We determined time and energy devoted to comfort activities in freely breeding king penguins (Aptenodytes patagonicus), seabirds known to fast for up to one month during incubation shifts ashore. A time budget was estimated from focal and scan sampling field observations and the energy cost of comfort activities was calculated from the associated increase in heart rate (HR) during comfort episodes, using previously determined equations relating HR to energy expenditure. We show that incubating birds spent 22% of their daily time budget in comfort behavior (with no differences between day and night) mainly devoted to preening (73%) and head/body shaking (16%). During comfort behavior, energy expenditure averaged 1.24 times resting metabolic rate (RMR) and the corresponding energy cost (i.e., energy expended in excess to RMR) was 58 kJ/hr. Energy expenditure varied greatly among various types of comfort behavior, ranging from 1.03 (yawning) to 1.78 (stretching) times RMR. Comfort behavior contributed 8.8-9.3% to total daily energy expenditure and 69.4-73.5% to energy expended daily for activity. About half of this energy was expended caring for plumage. This study is the first to estimate the contribution of comfort behavior to overall energy budget in a free-living animal. It shows that although breeding on a tight energy budget, king penguins devote a substantial amount of time and energy to comfort behavior. Such findings underline the importance of comfort behavior for the fitness of colonial seabirds.

    Biometeorological indices are used to asses thermal comfort conditions and evaluate the influence of the weather on the human organism and health. Despite of the fact, that some biometeorological indices are already used in weather forecast, the assessment of these indices is especially important during the extreme weather conditions like continuous heat or cold waves. One of the very urgent issues in the applied climatology is the assessment of thermal comfort conditions in the urban areas, because nowadays more than half population of the planet lives there. Especially important is to study thermal comfort conditions in biggest and, thus, densely populated cities, because the effect of heat waves becomes stronger by the urban heat island effect. In July and August 2010 in the biggest city in Russia - Moscow, where more than 11 million people live, the longest and the strongest heat wave as well as the warmest day (29th of July 2010) were recorded since the meteorological observations in Russian capital were started. The main objective of this work is to evaluate the thermal comfort conditions of the warmest day in Moscow. For that purpose several biometeorological indices, particularly PET (physiological equivalent temperature), were analyzed and calculated for the warmest day in Russian capital. The calculations were done for the certain city canyon on the territory of the Moscow State University as well as for the places with natural vegetation. The results were compared with each other and, thus, the complex thermal comfort assessment was done. Also, the results of the calculations for the 29th of July 2010 were compared with the mean meteorological data for this period.

    Full Text Available In order to clarify the comfort temperature and to investigate the behavioral adaptation in Japanese houses, we have conducted a thermal comfort survey and occupant behavior survey in 30 living rooms during the hot and humid season in the Kanto region of Japan. We collected 3991 votes from 52 subjects. The comfort temperature was predicted by Griffiths’ method. They are analyzed according to humidity levels and compared with the adaptive model. The logistic regression analysis was conducted in order to understand occupant behavior. The mean comfort temperature in naturally ventilated mode is 27.6 °C which is within the acceptable zone of the adaptive model. The comfort temperature is related with skin moisture sensation. The results showed that the residents adapt to the hot and humid environments by increasing the air movement using behavioral adaptation such as window opening and fan use.

    Comfort is a substantive need throughout life. However, the rise of technological influence coupled with a desire to embrace the medical concept of cure has frequently relegated the importance of nursing comfort interventions to simple tasks that can be provided by non-professional caregivers rather than an integral part of health promotion at all levels. Comfort is a concept that has been explored by a number of authors. Various definitions have included comfort as an outcome of nursing, a function of nursing, a basic human need, and a process. No consensus on a definition of comfort was found in the literature. This investigation attempts to link the ideas of comfort presented in the literature with the theories of Watson (Human Care) and Leininger (Culture Care), and discovers the existence of an integral locus for comfort in both. Theory-based strategies for nursing education are offered. Further research is clearly required, research methodologies based on Watson and Leininger would be appropriate for additional exploration of this concept. Practice implications include reflecting on the meaning of comfort to the patient in the context of his/her cultural values, and using this one as one of the factors in planning and implementing nursing care. Given the current emphasis on health promotion and the importance of comfort to the process of healing, comfort is an indispensable element of holistic, culturally congruent human care.

    Long-lived coherences (LLC’s) are detectable magnetisation modes with favourable relaxation times that translate as sharp resonances upon Fourier transform. The frequency domain of LLC's was previously limited to the range of J-couplings within pairs of homonuclear spins. LLC evolution at high magnetic fields needs to be sustained by radio-frequency irradiation. We show that LLC-based spectral dispersion can be extended beyond the J-couplings domain using adapted carrier offsets and introduce a new reduced-power sustaining method to preserve LLC's within the required range of offsets. Spectral resolution is enhanced as the natively narrow lines of LLC's are further dispersed, making them potential probes for the study of biomolecules featuring strong resonance overlap and for media where NMR spectroscopy is commonly hindered by line broadening.

  13. Thermal comfort assessment of buildings

    2013-01-01

    A number of metrics for assessing human thermal response to climatic conditions have been proposed in scientific literature over the last decades. They aim at describing human thermal perception of the thermal environment to which an individual or a group of people is exposed. More recently, a new type of “discomfort index” has been proposed for describing, in a synthetic way, long-term phenomena. Starting from a systematic review of a number of long-term global discomfort indices, they are then contrasted and compared on a reference case study in order to identify their similarities and differences and strengths and weaknesses. Based on this analysis, a new short-term local discomfort index is proposed for the American Adaptive comfort model. Finally, a new and reliable long-term general discomfort index is presented. It is delivered in three versions and each of them is suitable to be respectively coupled with the Fanger, the European Adaptive and the American Adaptive comfort models.

    Oases of learning which are transformative and lead to significant behavioural change can be found around the globe. Transformational learning has helped learners not only to understand what they have been taught but also to re-conceptualise and re-apply this understanding to their daily lives. Unfortunately, as many global reports indicate, inspirational transformational learning approaches for sustainable development are rare and have yet to become the norm - despite calls for such approaches by several outstanding educators and organisations. This article examines three learning approaches developed by the network of the Partnership for Education and Research about Responsible Living (PERL). These approaches are structured around core elements of transformative learning for sustainable development, yet focus particularly on the ability to care, consult with others and be creative. They seem to depend on the learners' ability to articulate their perceptions of sustainable development in relation to their own values and to identify how these are actualised in their daily life. Together with other core elements of transformative learning, an almost magical (not precisely measurable) synergy then emerges. The intensity of this synergy appears to be directly related to the individual learner's understanding of the contradictions, interlinkages and interdependencies of modern society. The impact of this synergy seems to be concurrent with the extent to which the learner engages in a continual learning process with those with whom he/she has contact. The findings of this study suggest that mainstreaming transformational learning for sustainable development in ways that release the "magic synergy of creative caring" can result in the emergence of individuals who are willing and able to move from "business as usual" towards more socially just, economically equitable, and environmentally sensitive behaviour.

    This study aimed to (1) explore how palliative care in long-term care (LTC) addresses the tensions associated with caring for the living and dying within one care community, and (2) to inform how palliative care practices may be improved to better address the needs of all residents living and dying in LTC as well as those of the families and support staff. This article reports findings from 19 focus groups and 117 participants. Study findings reveal that LTC home staff, resident, and family perspectives of end-of-life comfort applied to those who were actively dying and to their families. Our findings further suggest that eliciting residents' perceptions of end-of-life comfort, sharing information about a fellow resident's death more personally, and ensuring that residents, families, and staff can constructively participate in providing comfort care to dying residents could extend the purview of end-of-life comfort and support expanded integration of palliative principles within LTC.

  18. Evaluation of User Satisfaction in Relation to Comfort Conditions in Shopping Malls: Bursa as a Case

    Directory of Open Access Journals (Sweden)

    2014-04-01

    Full Text Available Enclosed shopping malls are one of the most preferred spaces in our daily lives. In these places, visual and climatic comfort conditions of the users are generally provided by artificial systems instead of natural ones. In order to provide user satisfaction which is one of the most important requirements for the viability of these centers, the usage of these artificial systems causes higher energy consumption. In this study, it is argued that spatial organization scheme of shopping malls affects the subjective thoughts of the users’ interior comfort conditions (thermal, interior space air quality, natural ventilation, day lighting, audial comfort. In this context, 7 large shopping malls in Bursa were selected as case studies and the questionnaire aiming to evaluate the users’ satisfaction about comfort conditions in these shopping malls was carried out. The aim of the study is to identify the effects of architectural design principles and spatial organization schemes on the users’ evaluation of comfort conditions. The results of the questionnaire are classified under subtitles such as interior heat, thermal comfort, interior air quality and natural ventilation, day lighting, audial comfort .In this context, at the end of the study, the relation between the users’ subjective evaluation of comfort conditions and architectural design principles are comparatively discussed and some suggestions for the design of new shopping malls are provided

    2016-10-01

    Full Text Available The strategies to reduce the consumption of non-renewable energies in buildings are becoming increasingly important. In the meantime, nature-inspired approaches have emerged as a new strategy to achieve thermal comfort in the interiors. However, the use of these approaches in architecture and buildings requires a proper understanding regarding the features of ecosystems. Although acquiring this knowledge requires a high degree of familiarity with the fields such as biology and environmental science, review of achievements made by the use of these features could facilitate the understanding of ecomimicry processes and thereby contribute to environmental sustainability in buildings. In other words, this paper concerns the relationship between these features and the thermal comfort inside the building. Biomimicry is an approach to innovation that seeks sustainable solutions to human challenges by emulating nature’s time-tested patterns and strategies. The objective of this paper is to use such review to provide an approach to the use of natural features for achieving thermal comfort in the buildings of hot and dry climates. In this review, the successful examples are analyzed to identify and examine the principles that influence the thermal comfort in both building and urban levels. The results show that the three elements of water, wind, sun are the effective natural resources that must be utilized in the design in a way proportional and consistent with the natural features. In addition, functional features of ecosystem can be of value only in the presence of a processual  relationship between them.

    2007-07-01

    In order to reduce heating costs and greenhouse gases, there is an interest in researching passive architectural design in low cost dwellings to eventually create sustainable dwellings with thermal comfort. This paper presented the results of a study that investigated the effect of Trombe walls in low-cost dwellings in Jordan. The study involved using the sun, a natural renewable source of energy in order to warm the thin walled structures. Experiments were performed on full-scale models in search of ways to raise the temperatures of the exterior walls through solar radiation as a green and renewable energy resource. A Trombe wall system was enhanced by a reflective membrane. It was tested on two full size chambers built with the same construction materials used in the Jordanian building industry. The paper discussed the study methodology and results. The expected heat loss was significant when the weather outside was cool amidst cloudy weather. A more effective Trombe wall system could be achieved by introducing automatic shutters which close once the sun is interrupted by clouds. 5 refs., 3 tabs., 3 figs.

    Full Text Available During the pacific war, about 80 to 200 thousand women were mobilized by the Japanese imperial army to sexually serve its soldiers, in one of world’s largest cases of human trafficking. Most of the victims, euphemistically known as "comfort women", came from Korea, Japan's colony at the time, and was attracted by false promises of employment or simply kidnapped by Japanese troops. Taken to military brothels throughout the pacific, they were subjected to repeated rape and beatings. Some of them, as young as age 12, were daily forced to have sex with Japanese soldiers, 10, 30, 50 times a day. The few women who survived and were able to return home at the end of the war continued to suffer for their past, through psychological trauma and social ostracism. They remained silent about their experience because of fear and shame. These women would have like to live in peace, being wives, mothers, sisters, grandmothers ... but this choice was denied to all. None received any compensation from the Japanese government official, who continues to evade its legal and moral responsibilities regarding war crime. Sixty-eight years later, they are still waiting for justice.

    Full Text Available In order to clarify effect of humidity on the room temperatures reported to be comfortable, an occupant thermal comfort and behavior survey was conducted for five summers in the living rooms and bedrooms of residences in the Kanto region of Japan. We have collected 13,525 thermal comfort votes from over 239 residents of 120 homes, together with corresponding measurements of room temperature and humidity of the air. The residents were generally well-satisfied with the thermal environment of their houses, with or without the use of air-conditioning, and thus were well-adapted to their thermal conditions. The humidity was found to have very little direct effect on the comfort temperature. However, the comfort temperature was strongly related to the reported skin moisture. Behavioral adaptation such as window opening and fan use increase air movement and improve thermal comfort.

    It is proposed that the emotional triggers of comfort food consumption can reliably be predicted by factors tied to affect asymmetry whereby negative affects dominate one's experience, decision making and behaviors in some instances while positive emotions prevail in others. Specifically, we relate three of these factors (age, gender, and culture) to differences in the emotional triggers of comfort food consumption and we further explore the possibility that the type of food eaten during comfort-seeking episodes can also be tied to affect asymmetry. Two hundred and seventy-seven participants completed a web-based survey conducted to assess the emotional antecedents and consequences of comfort food consumption. Consistent with expectations, results indicate that men's comfort food consumption was motivated by positive emotions whereas women's consumption was triggered by negative affects. Consumption of comfort foods alleviated women's negative emotions but also produced guilt. Positive affect was a particularly powerful trigger of comfort food consumption for older participants and for participants with French cultural background. Younger participants and participants with English background reported more intense negative emotions prior to consuming comfort foods. Foods high in sugar and fat content were more efficient in alleviating negative affects whereas low-calorie foods were more efficient in increasing positive emotions.

    The Solectrogen House near San Francisco was conceived, designed and built by Solar Depot as an off-grid renewable energy house. It is powered by a Solectrogen Hybrid Power System consisting of a 3 kW PV array, two 1 kW wind powered generators, a 50 kWh storage battery bank and a 6.5 kW LP-fueled engine generator for back-up. Two 4kW sinewave DC to AC inverters are utilized, with 24 VDC input and 120/240 VAC 60 Hz output. The inverters are equipped with built-in battery chargers and microprocessors for controlling the engine generator operation. The water supply of the house is a well pumped by a PV powered submersible DC pump. The swimming pool filtration system utilizes a 3/4 HP DC pump powered by a separate dedicated PV array of 640 Watts at 90 V. Energy efficient lighting and refrigeration used in the house minimize the power requirements of the house. The house also utilizes a solar thermal system consisting of 640 sq. ft. of glazed solar collectors and a 500 gallon storage tank. The thermal system is utilized for heating water year round, for space heating in the winter and for swimming pool heating in the summer.

    2010-01-01

    This report details a workshop held at the Bartlett School of Architecture, University College London, to initiate interdisciplinary collaborations for the practice of systems architecture, which is a new model for the generation of sustainable architecture that combines the discipline of the study of the built environment with the scientific study of complexity, or systems science, and adopts the perspective of systems theory. Systems architecture offers new perspectives on the organization of the built environment that enable architects to consider architecture as a series of interconnected networks with embedded links into natural systems. The public workshop brought together architects and scientists working with the convergence of nanotechnology, biotechnology, information technology, and cognitive science and with living technology to investigate the possibility of a new generation of smart materials that are implied by this approach.

    Today`s world faces unprecedented challenges in developing sustainable living styles that are supportable. This paper addresses the issues that relate to identifying problems and educating the public about the solutions to the problems. Wind energy should be part of the power production used in the world because it keeps the air and water clean, it makes jobs, and it can be done regionally. Educating the public in these areas is very complex. For several years this has been a puzzle, so to speak, which required a great deal of time, energy and money, all out of pocket, in order to raise awareness and develop a sense of what needed to be done. These are some of the ways that contacts have been made.

    2016-02-01

    Research has shown that a stable thermal environment with tight temperature control cannot bring occupants more thermal comfort. Instead, such an environment will incur higher energy costs and produce greater CO2 emissions. Furthermore, this may lead to the degeneration of occupants' inherent ability to combat thermal stress, thereby weakening thermal adaptability. Measured data from many field investigations have shown that the human body has a higher acceptance to the thermal environment in free-running buildings than to that in air-conditioned buildings with similar average parameters. In naturally ventilated environments, occupants have reported superior thermal comfort votes and much greater thermal comfort temperature ranges compared to air-conditioned environments. This phenomenon is an integral part of the adaptive thermal comfort model. In addition, climate chamber experiments have proven that people prefer natural wind to mechanical wind in warm conditions; in other words, dynamic airflow can provide a superior cooling effect. However, these findings also indicate that significant questions related to thermal comfort remain unanswered. For example, what is the cause of these phenomena? How we can build a comfortable and healthy indoor environment for human beings? This article summarizes a series of research achievements in recent decades, tries to address some of these unanswered questions, and attempts to summarize certain problems for future research. © 2015 John Wiley & Sons A/S.

    While thermal comfort in mass transportation vehicles is relevant to service quality and energy consumption, benchmarks for such comfort that reflect the thermal adaptations of passengers are currently lacking. This study reports a field experiment involving simultaneous physical measurements and a questionnaire survey, collecting data from 2,129 respondents, that evaluated thermal comfort in short- and long-haul buses and trains. Experimental results indicate that high air temperature, strong solar radiation, and low air movement explain why passengers feel thermally uncomfortable. The overall insulation of clothing worn by passengers and thermal adaptive behaviour in vehicles differ from those in their living and working spaces. Passengers in short-haul vehicles habitually adjust the air outlets to increase thermal comfort, while passengers in long-haul vehicles prefer to draw the drapes to reduce discomfort from extended exposure to solar radiation. The neutral temperatures for short- and long-haul vehicles are 26.2 degrees C and 27.4 degrees C, while the comfort zones are 22.4-28.9 degrees C and 22.4-30.1 degrees C, respectively. The results of this study provide a valuable reference for practitioners involved in determining the adequate control and management of in-vehicle thermal environments, as well as facilitating design of buses and trains, ultimately contributing to efforts to achieve a balance between the thermal comfort satisfaction of passengers and energy conserving measures for air-conditioning in mass transportation vehicles.

    Many years ago, Alex Comfort experimentally refuted Bidder's hypothesis that fish potentially were immortal. Later morphological and physiological studies, together with observations from fish populations in the wild, revealed that fish age in a way similar to that in other vertebrates. More recently, assessments of the age of fish have been revised, and have shown that some species live much longer than was estimated. These findings, together with the difficulties of demonstrating any increase in the rate of mortality with age in the long-lived, heavily exploited populations of fish, revived Bidder's ideas. I briefly review some of the more recent literature, and conclude that there is no evidence to suggest that fish are exceptional; like other vertebrates, sooner or later they grow old and die.

    To explore how parents interact with their infants and with nurses regarding the provision of comfort care in a Neonatal Intensive Care Unit (NICU). Focused ethnography. A regional NICU in the United Kingdom. Eleven families (10 mothers, 8 fathers) with infants residing in the NICU participated in the study. Parents were observed during a caregiving interaction with their infants and then interviewed on up to four occasions. Twenty-five periods of observation and 24 semistructured interviews were conducted between January and November 2008. Five stages of learning to parent in the NICU were identified. Although the length and duration of each stage differed for individual parents, movement along the learning trajectory was facilitated when parents were involved in comforting their infants. Transfer of responsibility from nurse to parents for specific aspects of care was also aided by parental involvement in pain care. Nurses' encouragement of parental involvement in comfort care facilitated parental proximity, parent/infant reciprocity, and parental sense of responsibility. Findings suggest that parental involvement in comfort care can aid the process of learning to parent, which is difficult in the NICU. Parental involvement in infant comfort care may also facilitate the transfer of responsibility from nurse to parent and may facilitate antecedents to parent/infant attachment. © 2012 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

    Historically thermal comfort in buildings has been controlled by simple dry bulb temperature settings. As we move into more sophisticated low energy building systems that make use of alternate systems such as natural ventilation, mixed mode system and radiant thermal conditioning strategies, a more complete understanding of human comfort is needed for both design and control. This guide will support building designers, owners, operators and other stakeholders in defining quantifiable thermal comfort parameters?these can be used to support design, energy analysis and the evaluation of the thermal comfort benefits of design strategies. This guide also contains information that building owners and operators will find helpful for understanding the core concepts of thermal comfort. Whether for one building, or for a portfolio of buildings, this guide will also assist owners and designers in how to identify the mechanisms of thermal comfort and space conditioning strategies most important for their building and climate, and provide guidance towards low energy design options and operations that can successfully address thermal comfort. An example of low energy design options for thermal comfort is presented in some detail for cooling, while the fundamentals to follow a similar approach for heating are presented.

    Birth and the newborn environment are stressful, especially for preterm infants who have to contend with medical conditions while adapting to the extrauterine world. Therefore, preterm newborns are excellent candidates for comforting measures. Skin-to-skin contact is the best way to provide comfort in several of the realms of Kolcaba's Comfort Theory. Evidence suggests that skin-to-skin contact between the mother and newborn changes the discomforting newborn environment into one that is profoundly comforting. Skin-to-skin contact promotes infant physiologic stability and warmth, helps in organizing infant sleep, reduces stress and pain, and makes breast milk readily available. Comfort to the newborn can be effectively accomplished by skin-to-skin contact.

    Goldsmith, T R

    1985-01-01

    The article examines the role of courage in breaking barriers which prevent friends unfamiliar with the health care industry from providing the needed support to sustain a friend during critical illness. "Fearful Saints" offers ways of understanding the complex issues which distance friends during illness. Close friends feel compelled to enter the world of suffering, but must first confront the terrifying images of illness. By examining Henri Nouwen's The Wounded Healer, and the story of Jesus asking his disciple Peter to wait with him in the garden, the concept of extending compassionate understanding during times of adversity becomes manageable. Although miracle potions may not be accessible, the reader learns to identify the role of comforter as one who will not permit an afflicted friend to travel through the experience alone.

    Human also has a thermoreceptor which is a non-specialized sensory receptor that has relative changes in temperature. Thermal comfort is a very important element for human body. Kitchen as an important part of a home is often forgotten. Cooking in the kitchen is a routine activity which is done from the morning until the evening; begin with preparing breakfast, lunch and dinner. The problem in this study was the occurance of heat when cooking in the kitchen without air conditioning in tropical countries. This research analyzes thermal comfort while doing cooking activities in conventional kitchen with gas stoves in tropical dry season. Two residential kitchens are observed by measuring the temperature and humidity as well as analyze other possible factors. Psychometric chart is used to assess the comfort zone in the kitchen. This research is using Predicted Mean Vote (PMV) Index and Predicted Percentage Dissatisfied (PPD) Index. By using online psychometric chart, the sensation is in warm condition with the range value of PMV between 1.73 up to 2.36 and PPD 63% untill 90%. However, 71% respondents perceived morning kitchen thermal as comfortable.

    2017-06-01

    Increased urbanization has led to a worsening in the quality of life for many people living in large cities in respect of the urban heat island effect and increases of indoor temperatures in housing and other buildings. A solution may be to retrofit existing environments to their former conditions, with a combination of green infrastructures applied to existing walls and rooftops. Retrofitted green roofs may attenuate housing temperature. However, with tall buildings, facade areas are much larger compared to rooftop areas, the role of green walls in mitigating extreme temperatures is more pronounced. Thus, the combination of green roofs and green walls is expected to promote a better thermal performance in the building envelope. For this purpose, a modular vegetated system is adopted for covering both walls and rooftops. Rather than temperature itself, the heat index, which comprises the combined effect of temperature and relative humidity is used in the evaluation of thermal comfort in small scale experiments performed in Sydney - Australia, where identical timber framed structures prototypes (vegetated and non-vegetated) are compared. The results have shown a different understanding of thermal comfort improvement regarding heat index rather than temperature itself. The combination of green roof and walls has a valid role to play in heat index attenuation.

    To better understand the influence of urban green infrastructure (UGI) on outdoor human thermal comfort, a survey and physical measurements were performed at the campus of the University of Groningen, The Netherlands, in spring and summer 2015. Three hundred eighty-nine respondents were interviewed in five different green spaces. We aimed to analyze people's thermal comfort perception and preference in outdoor urban green spaces, and to specify the combined effects between the thermal environmental and personal factors. The results imply that non-physical environmental and subjective factors (e.g., natural view, quiet environment, and emotional background) were more important in perceiving comfort than the actual thermal conditions. By applying a linear regression and probit analysis, the comfort temperature was found to be 22.2 °C and the preferred temperature was at a surprisingly high 35.7 °C. This can be explained by the observation that most respondents, who live in temperate regions, have a natural tendency to describe their preferred state as "warmer" even when feeling "warm" already. Using the Kruskal-Wallis H test, the four significant factors influencing thermal comfort were people's exposure time in green spaces, previous thermal environment and activity, and their thermal history. However, the effect of thermal history needs further investigation due to the unequal sample sizes of respondents from different climate regions. By providing evidence for the role of the objective and subjective factors on human thermal comfort, the relationship between UGI, microclimate, and thermal comfort can assist urban planning to make better use of green spaces for microclimate regulation.

    The unique geographical location of Hainan makes its climate characteristics different from inland areas in China. The thermal comfort of Hainan also owes its uniqueness to its tropical island climate. In the past decades, there have been very few studies on thermal comfort of the residents in tropical island areas in China. A thermal environment test for different types of buildings in Hainan and a thermal comfort field investigation of 1944 subjects were conducted over a period of about two months. The results of the survey data show that a high humidity environment did not have a significant impact on human comfort. The neutral temperature for the residents in tropical island areas was 26.1 °C, and the acceptable temperature range of thermal comfort was from 23.1 °C to 29.1 °C. Residents living in tropical island areas showed higher heat resistance capacity, but lower cold tolerance than predicted. The neutral temperature for females (26.3 °C) was higher than for males (25.8 °C). Additionally, females were more sensitive to air temperature than males. The research conclusions can play a guiding role in the thermal environment design of green buildings in Hainan Province. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Social media are growing in popularity and will play a key role in future sexual health promotion initiatives. We asked 620 survey participants aged 16 to 29 years about their time spent using social media and their comfort in receiving information about sexual health via different channels. Median hours per day spent using social network sites was two; 36% spent more than 2 hours per day using social network sites. In multivariable logistic regression, being aged less than 20 years and living in a major city (compared to rural/regional Australia) were associated with use of social media more than 2 hours per day. Most participants reported being comfortable or very comfortable accessing sexual health information from websites (85%), followed by a doctor (81%), school (73%), and the mainstream media (67%). Fewer reported being comfortable getting information from social media; Facebook (52%), apps (51%), SMS (44%), and Twitter (36%). Several health promotion programmes via social media have demonstrated efficacy; however, we have shown that many young people are not comfortable with accessing sexual health information through these channels. Further research is needed to determine how to best take advantage of these novel opportunities for health promotion. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Padding bandage is an essential component of the multi-layer compression system used for chronic venous management. Padding plays a critical role in managing pressure over bony prominences and ensuring uniform pressure distribution around the limb circumference. Moreover, it helps in the management of heat, moisture and body fluids or exudates during the course of treatment to provide comfort to the patients. To study the effect of structural and constructional parameters on the compressional (pressure absorption or distribution) and comfort (air, moisture and heat transmission) characteristics of the padding. This research focuses on the examination of polypropylene based nonwoven padding samples. Critical factors, i.e., fiber linear density, needling density and mass per unit area, have been chosen for this study to find their significance on the performance of padding. Simple laboratory based methods have been proposed to examine pressure reduction and comfort characteristics of the padding. Pressure absorption by the padding decreases with increase in mass per unit area and needling density of the padding. A padding composed of thicker fiber absorbs more pressure compared to padding made from thinner fiber. On examining comfort, it was found that the air and moisture vapor transmission increase with decrease in mass per unit area and needling density but have opposite effects with fiber linear density (phealth practitioners, fabric engineers and manufactures to understand the significance of fibrous materials and their role in compression management, and could be further used as design consideration to optimized padding performance.

    Eye cosmetics usage is commonplace and whilst some products such as eyeliner are applied with close proximity to the ocular surface, there is little knowledge of the short- and long-term ocular effects of eye cosmetic formulations. This study aimed to investigate the use of eye cosmetics and identify any relationships between ocular comfort and cosmetic usage. Results were collated from an online survey comprising 23 questions that recorded demographics, Ocular Surface Disease Index (OSDI) score, extent and range of eye cosmetic use and perceived comfort differences with and without eye cosmetics. The 1360 female respondents (median age 25, interquartile range 20-34 years) completed the survey; 83% reported using eye cosmetics regularly (≥ 3 times per week) with mascara being most commonly used. Fifty three per cent used at least three different eye cosmetics products regularly. OSDI scores of cosmetics users were similar to non-users (p = 0.083), but perceived comfort was greater when cosmetics were not used (p cosmetics users (use of products cosmetics were used. Median OSDI scores suggested a trend towards reduced comfort amongst eyeliner users (p = 0.07) although frequency and type of cosmetic products used did not appear to influence OSDI scores. This study shows the use of multiple eye cosmetics is extensive and associated with the perception of ocular discomfort. With such widespread use of these products, more research is required to assess the effect on the ocular surface and tear film, which may be underestimated.

    Full Text Available Carter suggests the concept of a “comfort zone” to explain the inability of dramatic African American programs to be successful on television. He argues that a workable formula has been developed for successful African American series, “portray black people in a way that would be acceptable to the millions of potential purchasers (whites of advertised products. That is, non-threatening and willing to ‘stay in their place.’”. Using a data set constructed from television ratings and shares, this study examines “black-centeredness” within the context of program success and failure. The comfort zone concept argues Black-centered television series are only successful in a comedic genre because White audiences, who have the majority of the ratings power, will only watch Black-centered series with which they are comfortable. The findings suggest that, in general, race, that is Black-centeredness, did not negatively influence program ratings or shares.

  20. Forty years of Fanger's model of thermal comfort: comfort for all?

    Science.gov (United States)

    van Hoof, J

    2008-06-01

    The predicted mean vote (PMV) model of thermal comfort, created by Fanger in the late 1960s, is used worldwide to assess thermal comfort. Fanger based his model on college-aged students for use in invariant environmental conditions in air-conditioned buildings in moderate thermal climate zones. Environmental engineering practice calls for a predictive method that is applicable to all types of people in any kind of building in every climate zone. In this publication, existing support and criticism, as well as modifications to the PMV model are discussed in light of the requirements by environmental engineering practice in the 21st century in order to move from a predicted mean vote to comfort for all. Improved prediction of thermal comfort can be achieved through improving the validity of the PMV model, better specification of the model's input parameters, and accounting for outdoor thermal conditions and special groups. The application range of the PMV model can be enlarged, for instance, by using the model to assess the effects of the thermal environment on productivity and behavior, and interactions with other indoor environmental parameters, and the use of information and communication technologies. Even with such modifications to thermal comfort evaluation, thermal comfort for all can only be achieved when occupants have effective control over their own thermal environment. The paper treats the assessment of thermal comfort using the PMV model of Fanger, and deals with the strengths and limitations of this model. Readers are made familiar to some opportunities for use in the 21st-century information society.

    2000-09-01

    The purpose of this study was to determine the relationships between foot and leg characteristics, shoe characteristics, and the short-term subjective comfort of three different pairs of athletic shoes. Static measurements of foot dimension and leg angles were taken from eighteen subjects. Subjects rated the comfort of three different athletic shoes for standing, walking and running. The shoes were quantified by internal dimensions, hardness, flexibility and torsional stiffness. Average comfort ratings decreased from standing to walking to running. One shoe seemed suited for only a small group of subjects. In contrast, another shoe was generally comfortable for a large group. Skeletal alignment, specifically eversion angle, was related to comfort for one shoe. Therefore, fit of the shoe is not sufficient for comfort. Skeletal alignment, shoe torsional stiffness and cushioning seem to be mechanical variables which may be important for comfort.

    Full Text Available This paper proposes to visualize acoustic comfort along tourist routes. Route-based tourism is crucial to the sustainability of tourism development in historic areas. Applying the concept of route-based tourism to guide tourists rambling along cultural and heritage routes can relieve overcrowded condition at hot scenic spots and increase the overall carrying capacity of the city. However, acoustic comfort along tourist routes is rarely addressed in academic studies and decision-making. Taking Macao as an example, this paper has studied pedestrian exposure to traffic noise along the cultural and heritage routes. The study is based on a GIS-based traffic noise model system with a high spatial resolution down to individual buildings along both sides of the street. Results show that tourists suffer from excessive traffic noise at certain sites, which may have negative impact on the promotion of route-based tourism in the long run. In addition, it is found that urban growth affects urban form and street layout, which in turn affect traffic flow and acoustic comfort in urban area. The present study demonstrates spatial techniques to visualize acoustic comfort along tourist routes, and the techniques are foreseen to be used more frequently to support effective tourism planning in the future.

    Full Text Available Preparation for fossil fuel substitution in the building sector persists as an essential subject in architectural engineering. Since the building sector still remains as one of the three major global end energy consumer – climate change is closely related to construction and design. We have developed the archetype sun space to what it is today : a simple but effective predominant naturally ventilated sun trap and as well as living space enlargement. With the invention of industrial glass orangery’s more and more changed from frost protecting envelopes to living spaces from which we meantime expect thermal comfort in high quality. But what level of thermal comfort provide sun spaces? And to what extend may sun spaces manage autarkic operation profiting from passive solar gains and, beyond that, surplus energy generation for energy neutral conditioning of aligned spaces? We deliver detailed information for this detected gap of knowledge. We know about limited thermal comfort in sun spaces winter times. This reasons the inspection of manifold collector technologies, which enable to be embedded in facades and specifically in sun space envelopes. Nonetheless, effective façade integrated collectors are ineffective in seasons with poor irradiation. Hence, the mismatch of offer and demand we have experienced with renewable energies ignites thinking about appropriate seasonal energy storages, which enlarges the research scope of this work. This PhD thesis project investigates on both, a yearly empirical test set up analysis and a virtual simulation of different oriented and located sun spaces abroad Germany. Both empirical and theoretical evaluation result in a holistic research focusing on a preferred occupation time in terms of cumulative frequencies of operational temperature and decided local discomfort, of potential autarkic sun space operation and prospective surplus exergy for alternative heating of aligned buildings.

    Full Text Available Improving energy performance of buildings is one of the most important tasks for reaching sustainability. Assessing building energy consumption is performed more often with specialized simulation tools. Sensitivity analysis proved to be a valuable tool for creating more reliable and realistic building energy models and better buildings. This paper briefly describes the methodology for running global sensitivity analysis and tools that can be used, and presents the results of such an analysis conducted for winter period, daily, on input variables covering a real building's operation, control and occupant related parameters that affect both thermal comfort and heating energy consumption. Two sets of inputs were created. The only difference between these sets is an addition of clothing insulation and occupant heat gain as input variables. The reference building was simulated for three distinctive winter weeks. Two additional input variables have an effect especially on thermal comfort, but they do not disturb the relative order of other influential input variables. The common influential variables for both energy consumption and thermal comfort were identified and are: air handling unit sup-ply temperature and airflow rate and control system related parameters. This can help in future research into implementing the simulation-assisted optimized operation in real buildings. [Projekat Ministarstva nauke Republike Srbije, br.

    A shoe wearer's comfort is related to the shape of the footbed of a shoe. Even though the footbed shape is important in footwear design, there exists no methodology to evaluate the existing guidelines used in last making. Thirty-two females participated in an experiment where heel seat length, heel seat inclination and heel height were investigated using the profile assessment device. The dependent variables were plantar pressure and perceived feeling of each participant. The results show that perceived feel is best for wedge angles of 4 degrees and 5 degrees at a heel height of 25 mm, 10 degrees and 11 degrees at a heel height of 50 mm and 16 degrees and 18 degrees at a heel height of 75 mm. A regression model was derived and this explained approximately 80% of the variation of perceived feeling with the contact area, peak plantar pressure and percentage of force acting on the forefoot region. Both heel wedge angle and heel seat length play an important role in the perceived feel of high-heeled shoes. This study, in relation to the load-bearing heel part of a shoe, highlights the importance of good footbed design. The findings can be used to design footwear with enhanced comfort.

    Full Text Available In the 21st century the mankind to came to understanding that the comfortable living environment is the basis of a high-quality life, which represents the strategic resource of the state. The comfortable environment consists of numerous factors, which include the social infrastructure as well. The author of the article stats with the statement that the project of creation of the comfortable urban environment includes: economical, commercial and budget efficiency of the project, ecological consequences or results of the project impact on the environment, contribution of the project implementable to improvement of the social environment. Developing such approach, the author comes to a wider concept of the life quality. Thus, all three elements of the project of creation of the comfortable urban environment influence the quality of life of the population. According to the research results, presented in the article it becomes obvious that medical-and-demographic characteristics are being improved when the development of housing is followed by the corresponding development of the social infrastructure. Thus, the author makes the conclusion that for the solution of the task of creation of the social infrastructure as the environment for a healthy lifestyle, development of managerial decisions, which are made not on intuition basis but on rational estimation taking into account above-mentioned factors are necessary.

    2018-01-01

    Full Text Available Two types of methods are used to evaluate pedestrian comfort: pedestrian wind comfort and outdoor thermal comfort. To accurately ascertain the outdoor wind environment, wind speed is the only parameter considered. However, pedestrians may still feel discomfort when the perceived temperature is low, even though the wind comfort criterion has been satisfactorily fulfilled. The purpose of this study is, therefore, to investigate pedestrian comfort when the perceived temperature is low, especially in winter conditions. To achieve this, a pedestrian survey was conducted, and 588 respondents completed a questionnaire. The results show that pedestrians feel discomfort when the WCET (Wind Chill Equivalent Temperature is low, with almost 40 percent of respondents answering that they feel discomfort in these conditions. In conclusion, the threshold wind speed of the winter season could be determined to be lower than that of the existing comfort criteria by applying the WCET.

    Building on findings related to physiological and psychological motivations of food preference, this research develops a framework to examine preferences toward comfort foods. Study 1 used a North American survey of 411 people to determine favored comfort foods, and Study 2 quantified the preferences for these foods across gender and across age groups using a stratified sample of 1005 additional people. Consistent with hypotheses, the findings showed different comfort food preferences across gender and across age. Males preferred warm, hearty, meal-related comfort foods (such as steak, casseroles, and soup), while females instead preferred comfort foods that were more snack related (such as chocolate and ice cream). In addition, younger people preferred more snack-related comfort foods compared to those over 55 years of age. Associations with guilty feelings underscored how these different preferences between males and females may extend to areas of application.

    To determine if rating of ocular comfort during soft contact lens wear is affected by demographic factors. Retrospective analysis of ocular comfort ratings during soft contact lens wear extracted from 44 nonrandomized similar clinical trials (n = 986). Subjects wore one of seven daily wear silicone hydrogels (SiHy) in combination with one of nine lens care products (LCP), and two daily disposables lenses. The effects on comfort rating of demographic factors were examined after adjusting for lens and LCP effects using general linear model. Males reported lower comfort on insertion than females (7.9 ± 1.6 vs. 8.1 ± 1.6, p = 0.001). Over 45 years old had higher comfort ratings than those between 26 and 45 or gender, lens wear experience, ethnicity, and refractive status can influence the rating of ocular comfort in clinical studies. The confounding effects of such demographic factors can be controlled by implementing randomization and appropriate multivariable statistical analysis.

    Gil-Mastalerczyk Joanna

    2016-01-01

    Full Text Available The emergence in recent decades of the idea of sustainability and sustainable development significantly affected the innovative approach to architectural design and urban planning. The article presents contemporary examples of the Polish works of sacred architecture and urban planning, which prove the unconscious use and incorporation of the concept of the architectural values of the environment, including climate, solar energy and other natural elements such as landform, structure or green water. The analysis of the contemporary examples of architecture, realized in the second half of the twentieth century, confirms that such actions are taken. The search for a friendly urban space combines the comfort of living with the comfort of the natural environment. The contemporary objects and sacral complexes testify to integrated planning with nature. The system of architectural and urban planning objectives is clearly reflected in the functioning of thecity and how to organize the use of space, including an attempt to rebuild a sustainable relationship between the infrastructure and the natural environment. When designing the contemporary forms, sacred has become very important in addition to the historical past, the identity of individual urban structures, at the same time, maintaining the high quality of the environment. Projecting of harmony with the local climate and the use of natural conditions in urban planning.

    There are many challenges facing the health system in the 21st century - the majority of which are related to managing demand for health services. To meet these challenges emerging GP commissioning consortia will need to take a new approach to commissioning health services - an approach that moves beyond the current acute-centred curative paradigm of care to a new sustainable paradigm of care that focuses on primary care, integrated services and upstream prevention to manage demand. A key part of this shift is the recognition that the health system does not operate in a vacuum and that strategic commissioning decisions must take account of wider determinants of health and well-being, and operate within the finite limits of the planet's natural resources. The sustainable development principle of balancing financial, social and environmental considerations is crucial in managing demand for health services and ensuring that the health system is resilient to risks of resource uncertainty and a changing climate. Building sustainability into the governance and contracting processes of GP commissioning consortia will help deliver efficiency savings, impact on system productivity, manage system risk and help manage demand through the health co-benefits of taking a whole systems approach to commissioning decisions. Commissioning services from providers committed to corporate social responsibility and sustainable business practices allows us to move beyond a health system that cures people reactively to one in which the health of individuals and populations is managed proactively through prevention and education. The opportunity to build sustainability principles into the culture of GP commissioning consortia upfront should be seized now to ensure the new model of commissioning endures and is fit for the future.

    Climate change and the urgency of decarbonizing the built environment are driving technological innovation in the way we deliver thermal comfort to occupants. These changes, in turn, seem to be setting the directions for contemporary thermal comfort research. This article presents a literature review of major changes, developments, and trends in the field of thermal comfort research over the last 20 years. One of the main paradigm shift was the fundamental conceptual reorientation that has taken place in thermal comfort thinking over the last 20 years; a shift away from the physically based determinism of Fanger's comfort model toward the mainstream and acceptance of the adaptive comfort model. Another noticeable shift has been from the undesirable toward the desirable qualities of air movement. Additionally, sophisticated models covering the physics and physiology of the human body were developed, driven by the continuous challenge to model thermal comfort at the same anatomical resolution and to combine these localized signals into a coherent, global thermal perception. Finally, the demand for ever increasing building energy efficiency is pushing technological innovation in the way we deliver comfortable indoor environments. These trends, in turn, continue setting the directions for contemporary thermal comfort research for the next decades. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Automotive ergonomics is a set of knowledge which has a task to design a vehicle to make the passengers feel comfortable. Interior packaging represents an important stage in the vehicle design process, in order to enable the driver to every important aspect of movement. During the process of driving, the driver performs various movements of arms and legs, leading to a certain fatigue. Each seating position in the vehicle, contain certain boundary conditions, and for that reason it was necessary to examine how the seating position affects the driver possibilities. In this paper, the pedal forces were determined by application of Ramsis human model. Different human populations were taken into account. Correlation between subjects’ anthropometrics measures and the foot pedal force pedal was observed. Obtained results were significant input data for vehicle packaging.

    Knitted denim was designed by using cross terry structure on circular knitting machine. Knitted denim looks like a denim fabric which has visual appearance like woven denim. Two type of cross terry structure 2/1 and 3/1 were used which gives twill effect with 2 and 3 floats respectively. Four types of materials, cotton, polyester, flax and polypropylene were used. With four materials and two structural combinations 8 samples were produced. Comfort properties of knitted denim including moisture management, air permeability, thermal, and bursting strength were tested. For checking the inherent anti-microbial property of materials anti-microbial test was also applied. Samples containing flax and polyester were found with best results and not even a single sample was found anti-microbial.

    The aim of this paper is to investigate the local differences between body segments caused by high radiant temperature, and to analyze the interior surface temperatures for different wall and ceiling constructions with their effect on thermal comfort. For the segment-wise thermal interactions between human body and its surrounding, simulations have been conducted by appropriately modifying Gagge 2-node model to multi-segment case to demonstrate the local differences. Simulation results are found to be in good agreement with experimental and simulation results reported in the literature. To calculate the interior surface temperatures of the wall and ceiling, the sol-air temperature approach is used for convenience. It is shown in the paper that the body segments close the relatively hot surfaces are more affected than others and interior surface temperatures of un-insulated walls and ceilings exposed to a strong solar radiation reach high levels, all of which cause thermal discomfort for the occupants in buildings.

    Full Text Available The hydrothermal microclimate is the main component in indoor comfort. The optimum hydrothermal level can be ensured by suitable changes in the sources of heat and water vapor within the building, changes in the environment (the interior of the building and in the people exposed to the conditions inside the building. A change in the heat source and the source of water vapor involves improving the heat - insulating properties and the air permeability of the peripheral walls and especially of the windows. The change in the environment will bring human bodies into balance with the environment. This can be expressed in terms of an optimum or at least an acceptable globe temperature, an adequate proportion of radiant heat within the total amount of heat from the environment (defined by the difference between air and wall temperature, uniform cooling of the human body by the environment, defined a by the acceptable temperature difference between head and ankles, b by acceptable temperature variations during a shift (location unchanged, or during movement from one location to another without a change of clothing. Finally, a moisture balance between man and the environment is necessary (defined by acceptable relative air humidity. A change for human beings means a change of clothes which, of course, is limited by social acceptance in summer and by inconvenient heaviness in winter. The principles of optimum heating and cooling, humidification and dehumidification are presented in this paper.Hydrothermal comfort in an environment depends on heat and humidity flows (heat and water vapors, occurring in a given space in a building interior and affecting the total state of the human organism.

    Full Text Available Dwellings in multi-storey apartment buildings (MSAB are predicted to increase dramatically as a proportion of housing stock in subtropical cities over coming decades. The problem of designing comfortable and healthy high-density residential environments and minimising energy consumption must be addressed urgently in subtropical cities globally. This paper explores private residents’ experiences of privacy and comfort and their perceptions of how well their apartment dwelling modulated the external environment in subtropical conditions through analysis of 636 survey responses and 24 interviews with residents of MSAB in inner urban neighbourhoods of Brisbane, Australia. The findings show that the availability of natural ventilation and outdoor private living spaces play important roles in resident perceptions of liveability in the subtropics where the climate is conducive to year round “outdoor living”. Residents valued choice with regard to climate control methods in their apartments. They overwhelmingly preferred natural ventilation to manage thermal comfort, and turned to the air-conditioner for limited periods, particularly when external conditions were too noisy. These findings provide a unique evidence base for reducing the environmental impact of MSAB and increasing the acceptability of apartment living, through incorporating residential attributes positioned around climate-responsive architecture.

    Measures of comfort are important in the prescription and development of footwear. The purpose of our study was to examine three commonly used scales (visual analog scale (VAS), Likert scale, and ranking scale) to determine the most reliable, to calculate a minimal clinically important change in rating scales, and to explore dimensions of comfort important to the patient. Twenty subjects were allocated consecutively to two experiments consisting of five sessions of repeated measures. Using comfort measures from each subject's usual jogging shoe, experiment 1 examined the reliability of VAS and Likert scale over six dimensions of the foot, including overall comfort. The second experiment examined the reliability of ranking scale by assessing the ranked position of the shoe. Comfort measures were obtained in both walking and jogging. The ranking scale was the most stable scale. Mixed linear modeling found that VAS was more stable than the Likert scale. The VAS required two sessions to become reliable for all measures but those obtained from the heel, which required more. Using a data-derived approach, a clinically important change in comfort was 9.59 mm on the 100-mm VAS; using an anchor-based approach, it was 10.2 mm. Subjects identified arch comfort as the most important consideration in footwear comfort. Ranking scale and VAS are reliable measures of footwear comfort. Using the VAS, changes of 9.59 and 10.2 mm indicate a clinically relevant change in comfort. The most important dimensions to the patient are overall comfort and the arch.

    A human life demand set to emerge in the future is the achievement of sustainability by maintaining a comfortable indoor environment without excessive reliance on energy-consuming air conditioners. The major research processes in this study are: (1) measuring indoor air quality and thermal comfort to evaluate the comfort of an indoor environment; (2) implementing questionnaire survey analysis to explore people's environmental self-perceptions and conducting a meta-analysis of the measurement results for air quality and physical aspects; and (3) constructing an indoor monitoring and management system. The experimental and analysis results of this research reveal that most of the office occupants preferred a cooler environment with a lower temperature. Additionally, because the summers in Taiwan are humid and hot, the occupants of an indoor space tend to feel uncomfortable because of the high humidity and poor indoor air quality. Therefore, Variable Air Volume (VAV), two air intakes, and exhaust plant are installed to improve indoor environment. After improvement, a lower temperature (approximately 21.2-23.9°C) indirectly reduces humidity, thereby making the occupants comfortable. Increasing air velocity to 0.1~0.15 m/s, the carbon dioxide concentrations decrease below the requirement of the WHO. Ninety-five percent of the workers corresponded to the standard comfort zone after this improvement.

    Emerging demographic trends signal that White Americans will soon relinquish their majority status. As Whites' acclimation to an increasingly diverse society is poised to figure prominently in their adjustment, identifying sources of greater comfort with diversity is important. Three studies (N = 519) revealed evidence that purpose in life bolsters comfort with ethnic diversity among White adults. Specifically, dispositional purpose was positively related to diversity attitudes and attenuated feelings of threat resulting from viewing demographic projections of greater diversity. In addition, when primed experimentally, purpose attenuated participants' preferences for living in an ethnically homogeneous-White city, relative to a more diverse city when shown maps displaying ethno-demographic information. These effects persisted after controlling for positive affect and perceived connections to ethnic out-groups, suggesting the robust influence of purpose. Potential benefits of situating purpose as a unique resource for navigating an increasingly diverse society are discussed. © 2014 by the Society for Personality and Social Psychology, Inc.

    Based on behavioral and neurobiological data, we tested the hypothesis that viewing/drawing visual images of comfort foods in the absence of eating will increase positive mood and that this effect is augmented for those with clinical symptoms of depression. A counterbalanced design was used for 60 participants with and without clinical symptoms in two variations: food image and food art. In each variation, participants viewed/drew foods high or low in fat/sugar; pre-post mood was recorded. Results show a consistent pattern: viewing/drawing comfort foods [food image (95% confidence interval): 2.72-4.85; food art (95% confidence interval): 2.65-4.62] and fruits [food image (95% confidence interval): 1.20-2.23; food art (95% confidence interval): 1.51-2.56] enhanced mood. For comfort foods, mood was augmented for those with clinical symptoms of depression [food image (95% confidence interval): 0.95-3.59; food art (95% confidence interval): 0.97-3.46]. Findings corroborate previous data and reveal a novel finding of augmented mood increases for those with clinical symptoms.

  1. Thermal (dis)comfort experienced from physiological movements across indoor, transitional and outdoor spaces in Singapore: A pilot study

    2017-04-01

    Human thermal comfort research is important as climate discomfort can adversely affect both health and work productivity in cities; however, such biometeorological work in low-latitude urban areas is still relatively unstudied hitherto. In the tropical metropolis of Singapore, a suite of policies have been implemented aimed at improving environmental sustainability via increasing car-free commutes and pedestrian movement during work/school journeys, with the consequence that individuals will likely have increased personal exposure through a variety of spaces (and climates) during typical daily activities. As such, research into exploring the thermal (dis)comfort experienced during pedestrian movements across these indoor, outdoor and transitional (semi-outdoor) spaces would yield interesting applied biometerological insights. This pilot study thus investigates how pedestrian thermal comfort varies spatially across a university campus, and how the physical intensity of pedestrian travel affects thermal comfort across these spaces. Over a 10-week period, we profiled six students for both their objective and subjective pedestrian thermal comfort during traverses across different spaces. Data were obtained through use of (a.) of a heat stress sensor, (b.) a fitness tracker, and (b.) a questionnaire survey to record traverse measurements of the microclimate, their physiological data, and their perceived microclimate comfort respectively. Measured climate and physiological data were used to derive commonly-used thermal comfort indices like wet-bulb globe temperature (WBGT) and physiological equivalent temperature (PET). Further, interviews were conducted with all six subjects at the end of the fieldwork period to ascertain details on individual acclimatization behavior and adaptation strategies. The results indicate that (a.) more than 50% of the microclimatic conditions within each indoor, semi-outdoor, and outdoor space exceeded heat stress thresholds of both PET and

    This study compared the effects of pre-experience and expectations on participant comfort upon waking, arrival to, and after an appointment, as well as the assessment of properly placed Feng Shui elements in three healthcare waiting rooms. Participants assessed comfort levels using self-report surveys. The researcher conducted 'intention interviews' with each doctor to assess the goals of each waiting area design, and conducted a Feng Shui assessment of each waiting area for properly placed Feng Shui elements. The waiting area designed by the Feng Shui expert rated 'most comfortable', followed by the waiting area design by a doctor, and the lowest comfort rating for the conventional waiting room design. Results show a sufficiently strong effect to warrant further research. Awareness of the external environment, paired with pre-experience and expectation, influences comfort for people over time. Fostering and encouraging a holistic approach to comfort utilizing eastern and western concepts and ergonomic principles creates a sense of "placeness" and balance in the design for comfort in built environments. This is new research information on the influences of the comfort experience over time, to include pre-experience, expectations and the placement of elements in the external environment.

    Full Text Available The natural environment is of great importance when it comes to developing a city, as it shapes its spaces, defines its roles and performs climatic and protective functions. Industrialization often requires removing landscape obstacles and vegetation to erect new buildings. An urban planner, though, should be aware of the borders that must not be crossed. Designing new streets and buildings should follow a sustainable growth pattern, if the city landscape and its climatic conditions are to improve for generations to come. This paper discusses the aspects of planning and managing urban spaces in such a way as to provide their users with healthy and comfortable living conditions. The paper is based on a survey conducted to gather the opinions of members of a city community on the environment in which they live.

    Human health is becoming an increasingly important issue in contemporary hectic lifestyle imposed at work and by struggle to save time and money. Sitting comfort and quality of chairs which we use for the most of our time have, thus, become essential for healthy lifestyle. Sitting discomforts arise from prolonged sitting on the inappropriate chairs, which failing to provide sufficient support to the body cause discomfort and tiring. The studies of the office chair constructions have identified differences in perception of comfort provided by different types of seats. Four seat constructions and the comfort they provide to the sitters were compared by means of subjective indicators. After a two-day sitting on each of the studied chairs the subjects scored their perception of comfort and discomfort, using the questionnaire with 17 statements. Constructional forms and materials which contributed more to the sense of comfort by minimizing fatigue and pains developed by sitting were determined.

    2010-12-15

    The aim of the research is to investigate the notion of passive houses in Denmark. When this PhD thesis was initiated, the Danish building industry has just started to become interested in the passive house concept, but the knowledge was very limited. To be able to speed up the process of constructing Danish passive houses or other low energy concepts Saint-Gobain Isover Scandinavia took the initiative to the pilot project of the Comfort Houses, ten single-family houses constructed as passive houses, and wanted to share the knowledge with the building industry and other interested. This PhD thesis was a part of the strategy. If the concept of passive houses should be successfully promoted and achieve a significant sale in Denmark, it is believed that it is necessary to do a holistic approach. Besides energy savings and new structural solutions more qualitative aspects like architecture, everyday life and the future ways of living needs to be integrated in the future understanding of passive houses. This Ph.D. thesis therefore studies the following research question: What can the experience from the Comfort Houses enlighten about the future production and use of Danish passive houses? This understanding is achieved through studies of different study fields to be able to create a more holistic understanding of the concept both covering qualitative and quantitative analysis. The main focus will be on the study fields Design Process, Architecture and Everyday Life and the Indoor environment, which will answer the following sub-research questions: 1) How has the consortiums behind the Comfort Houses approached the design process according to teamwork, method and tools? And what barriers and possibilities lie within the approaches? 2) How do the occupants of the Comfort Houses experience the passive house architecture and the technical service systems? And has their everyday life changed by moving into a passive house? If so, how? 3) To what extent do the Comfort Houses

    The burden of cancer in low- to middle-income countries is growing and is expected to rise dramatically while resources to manage this disease remain inadequate. All authorities for the management of cancer recommend multidisciplinary care. Educational efforts by international organizations to assist local professionals in caring for their patients tend to have a lasting impact because they empower local professionals and enhance their skills. A multidisciplinary cancer management course was designed by American Society of Clinical Oncology staff and local experts to provide a roadmap for cross-specialty interaction and coordination of care in Zimbabwe. The outcome of the course was measured through feedback obtained from participants and impact on local workforce. The cancer management course was relevant to daily practice and fostered long-lasting partnerships and collaborations. Furthermore, it resulted in a more motivated local workforce and strengthened existing multidisciplinary practices. Cancer care is in a critical state in low- to middle-income countries. Educational efforts and collaborative partnerships may provide a cost-effective strategy with sustainable benefits. A multidisciplinary approach to optimize therapy is desirable. Evaluation of the course impact after a period of 6 months to 1 year is needed to determine the sustainability and impact of such efforts.

  20. Parametric Modelling and Traditional Architecture: Improving the thermal comfort of the traditional courtyard house in Morocco

    2018-01-01

    Full Text Available The traditional courtyard house of the Mediterranean Basin has been viewed as a complex regulating system that creates a microclimate which historically worked, and still works, in a passive way to provide acceptable thermal comfort in summer. The internal courtyard is generally described as a positive factor that can moderate extreme outdoor climatic conditions. However, some researches have shown that the courtyard could become a negative factor from the energy efficiency point of view. For this purpose, this paper is based on a research study exploring sustainable characteristics of Moroccan traditional housing and its climatic adaptation, delving into the Rabat-Salé case study. A traditional courtyard model is used as a case study to analyze the indoor thermal comfort without using mechanical heating and cooling systems. The thermal behavior of the rooms surrounding the courtyard is analyzed under a temperate and humid climate of Rabat-Salé medina. The simulation modelling is carried out to analyze the effectiveness of different parameters to improve the indoor climate during summer and winter, including the façade orientation, the air infiltration, the surroundings, the ceiling height, the walls and roof/ceiling insulation and the shading devices. Tools for climatic design, Mahoney’s tables, Givoni and Szokolay bio climatic diagrams have been also used to improve design strategies in terms of thermal comfort.

    The manipulation of the composition of foods consumed as between-meal snacks may aid daily energy restriction. We compared the effects of the consumption of 2 energy-matched snack bars on appetite, energy intake (EI), and metabolic and endocrine responses. In addition, we investigated whether the acute effects of the consumption of snacks were maintained under free-living conditions and whether the habitual daily consumption of the snack over 14 d influenced these effects. Ten lean men [mean ± SD age: 30.7 ± 9.7 y; body mass index (in kg/m(2)): 23.2 ± 2.8] consumed a whey protein and polydextrose (PPX) snack bar or an isoenergetic control snack bar as a midmorning, between-meal snack for 14 consecutive days in a double-blind, randomized, crossover design. The two 14-d intervention phases were separated by a 14-d washout period. On the first (day 1) and last (day 15) days of each intervention phase, appetite, food intake, and blood metabolite and endocrine responses were assessed under laboratory conditions. Free-living EI was recorded on days 4, 8, and 12 of interventions. Total daily EI was significantly lower when the PPX snack was consumed during experimental days (10,149 ± 831 compared with 11,931 ± 896 kJ; P snack was consumed during the free-living part of the intervention (7904 ± 610 compared with 9041 ± 928 kJ; P snack was associated with lower glucose and ghrelin and higher glucagon-like peptide 1 and peptide tyrosine-tyrosine responses. The manipulation of the composition of foods consumed as snacks is an effective way to limit subsequent EI. This trial was registered at clinicaltrials.gov as NCT01927926.

    To analyse the psychometric properties and the utility of instruments used to measure patient comfort, physical, social, psychospiritual and/or environmental, during hospitalization. There are no systematic reviews nor psychometric reviews of instruments used to measure comfort, which is considered an indicator of quality in health care associated with quicker discharges, increased patient satisfaction and better cost-benefit ratios for the institution. Psychometric review. MEDLINE, CINAHL, PsycINFO, Web of Knowledge, ProQuest Thesis&Dissertations, Google. We limited our search to studies published between 1990-2015. The psychometric analysis was performed using the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN), along with the Quality Criteria for Measurement Properties. The utility of the instruments was assessed according to their cost-efficiency, acceptability and educational impact. Protocol registration in PROSPERO, CRD42016036290. Instruments reviewed showed moderate methodological quality and their utility was poorly reported. Thus, we cannot recommend any questionnaire without reservations, but the Comfort Scale, the General Comfort Questionnaire and their adaptations in adults and older patients, the Psychosocial Comfort Scale and the Incomfort des Patients de Reanimation are the most recommendable instruments to measure comfort. The methodology of the studies should be more rigorous and authors should adequately report the utility of instruments. This review provides a strategy to select the most suitable instrument to assess patient comfort according to their psychometric properties and utility, which is crucial for nurses, clinicians, researchers and institutions. © 2017 John Wiley & Sons Ltd.

    Full Text Available ‘Are intelligent buildings a pragmatic approach towards achieving a sustainable built environment?’ is the research question that this review article aims to answer. It has been argued that there is a serious need for intelligent buildings to be evaluated against the parameters of total sustainability (environmental, economic and social so as to help the agenda of living in a technologically advanced, healthy and comfortable world. This paper reviews existing theoretical concepts of intelligence and sustainability in the built environment, through an exploration of various scientific literature and U.S Green Building Council’s LEED (Leadership in Energy and Environmental Design databases. A systematic qualitative review approach has been employed to select an appropriate definition of sustainable development and use it as a theoretical framework to assess the technological impact of intelligent buildings on the environmental, economic and social front. Subsequently five case study buildings from around the world, which exemplify the use of intelligent technologies to achieve sustainable gains were chosen and analyzed to further validate the literature findings. Outputs from the study highlight the various benefits of intelligent buildings, which include decrease in energy and water consumption, operational costs, as well as increase in productivity and investments. Additionally the analysis of the case studies revealed that the use of intelligent building technologies has contributed significantly towards a higher sustainability rating on the LEED rating scale. Moreover, the comparison of the attributes of intelligent buildings and sustainable practices in buildings, illustrates the fact that there is a considerable overlap between the two and intelligence can aid sustainability in the built environment. Thus the research suggests that green technologies and intelligence in combination may be a pragmatic approach towards the sustainability

    To evaluate comfort and noise intensity using the COMFORT scale in infants who receive respiratory support with a helmet interface. An observational descriptive study was conducted on all infants (1 to 12 months of age) admitted to a PICU from November 1st 2013 to March 31st 2014 and who received non-invasive ventilation with a helmet interface. Tolerance to the interface was assessed by use of the COMFORT scale. The intensity of the noise to which the infants were exposed was measured with a TES1350A HIBOK 412 sound-level meter. Three measurements were made every day. Twenty seven patients with bronchiolitis (median age: 54 days; range: 10 to 256) were included. Median COMFORT score in the first day was 21 points (14 - 28). An increase in patient comfort was found with a gradual decrease in the scores, with a maximum reduction of 22% from the first hours (score of 22) to the fifth day (score of 18). The minimum sound intensity registered was 42dB, and the maximum was 78dB. Background noise intensity was associated with noise intensity in the helmet. No differences were observed in COMFORT score and noise intensity between ventilator devices. Helmet interface was well tolerated by infants. COMFORT score results are an indicator that infants were comfortable or very comfortable. The measured noise intensity was in the safe range permitted by World Health Organization.

    2017-01-01

    Full Text Available Located in the subtropics, the high temperature in summer affects indoor living environments in Taiwan. The use of perspective glass material for modern public buildings increases the transparency of landscape views; however, the solar radiation heat also increases the heat in indoor environment. In particular, visitor centers which offer service functions for large quantities of visitors should satisfy the demands for indoor environment comfort and energy saving. “Numerical simulation” and “field data” are therefore utilized in this study for mutual comparison and the analyses of duration of sunshine, temperature distribution, heat balance, and space comfort. The research result reveals that different building envelope materials, with distinct thermal resistance and thermal conductivity coefficients, as well as sunshine direction and duration, affect the heat transmitting indoors, change the indoor temperature and further influence the comfort of the indoor environment. In the future indoor venue comfort will affect visitors’ recreational behaviours.

    In this paper, we address the challenge of predicting optimal comfort temperatures of individual users of a smart heating system. At present, such systems use simple models of user comfort when deciding on a set point temperature. These models generally fail to adapt to an individual user’s preferences, resulting in poor estimates of a user’s preferred temperature. To address this issue, we propose a personalised thermal comfort model that uses a Bayesian network to learn and adapt to a user’...

    Malaysian Government takes an initiative to provide library in housing areas to improve the quality of human capital. However, the government has to evaluate every aspect of their provision to ensure the services provided meet the demands of the users, including the aspect of thermal comfort in the building. For this study, a library constructed using Industrialised Building System (IBS) are selected for thermal comfort evaluation. The data were analyzed using Corrected Effective Temperature (CET) index. From the data analysis, it shows that thermal comfort in the library could not be achieved most of the time unless when the mechanical cooling is used. A series of technical design improvements are then recommended to improve the thermal comfort inside the library by incorporating construction details without increasing the cost.

    Full Text Available Cabin HVAC (Heating Ventilation and Air-conditioning systems have become an essential part of personal vehicles as demands for comfortable transport are still rising. In fact, 85 % of the car trips in Europe are shorter than 18 km and last only up to 30 minutes. Under such conditions, the HVAC unit cannot often ensure desired cabin environment and passengers are prone to experience thermal stress. For this reason, additional comfort systems, such as heated or ventilated seats, are available on the market. However, there is no straightforward method to evaluate thermal comfort at the contact surfaces nowadays. The aim of this work is to summarise information about heated and ventilated seats. These technologies use electrical heating and fan driven air to contact area in order to achieve enhanced comfort. It is also expected, that such measures may contribute to lower energy consumption. Yet, in real conditions it is almost impossible to measure the airflow through the ventilated seat directly. Therefore, there is a need for an approach that would correlate measurable physical phenomena with thermal comfort. For this reason, a method that exploits a measurement of temperatures and humidity at the contact area is proposed. Preliminary results that correlate comfort with measurable physical phenomena are demonstrated.

    2008-08-01

    To investigate the influence of three lubricants of varying viscosity, on postinsertion and 6 h comfort with contact lens wear. Comfort and associated symptoms of dryness were assessed in 15 experienced contact lens wearers. Subjects wore a low Dk lens in one eye and a silicone hydrogel in the other and participated in four separate trials involving no lubricant (baseline), saline, and two commercially available lubricants of differing viscosity. The in-eye lubricants were used immediately following lens insertion and every 2 h postinsertion for a 6 h wear period. Postlens insertion comfort was significantly better for both lens types when lubricants or saline were used compared with no lubricant use. After 6 h lens wear, comfort was influenced by lens type and not by in-eye lubricant or saline use. Also after 6 h lens wear, less dryness sensation was reported for silicone hydrogel lenses when using lubricants but not saline. Although lubricant use does help reduce dryness symptoms with silicone hydrogel lens wear, there appears to be minimal longer-term benefit to comfort. Furthermore, increased lubricant viscosity did not lead to improved longer-term comfort.

    Tree-shaded outdoors can reduce the heat effect by ameliorating the microclimate and enhancing the human thermal comfort outdoors; for this reason, they are main places for rest, recreation and social activity in Taiwan's cities. Field comfort surveys of 3839 interviewees were conducted in tree-shaded spaces throughout a year. The aims were to obtain a better understanding of human thermal comfort response outdoors and to propose an adaptive comfort model for tree-shaded spaces. A comfort zone, centering on neutral operative temperature which is an empirically derived linear function of mean monthly outdoor temperature, of 6 C for 90% acceptability and 8 C for 80% acceptability was suggested for tree-shaded spaces from surveyed data, adding that a non-linear function of the temperature difference between actual operative temperature and neutral operative temperature was established that aims to predict the percentage of heat or cold discomfort at a particular outdoor thermal condition. An application of the established adaptive comfort model on an actual tree-shaded space was demonstrated to show its practicality in long-term evaluation of a particular thermal environment.

  3. Thermal comfort in air-conditioned buildings in hot and humid climates--why are we not getting it right?

    2016-02-01

    While there are plenty of anecdotal experiences of overcooled buildings in summer, evidence from field studies suggests that there is indeed an issue of overcooling in tropical buildings. The findings suggest that overcooled buildings are not a consequence of occupant preference but more like an outcome of the HVAC system design and operation. Occupants' adaptation in overcooled indoor environments through additional clothing cannot be regarded as an effective mitigating strategy for cold thermal discomfort. In the last two decades or so, several field studies and field environmental chamber studies in the tropics provided evidence for occupants' preference for a warmer temperature with adaptation methods such as elevated air speeds. It is important to bear in mind that indoor humidity levels are not compromised as they could have an impact on the inhaled air condition that could eventually affect perceived air quality. This review article has attempted to track significant developments in our understanding of the thermal comfort issues in air-conditioned office and educational buildings in hot and humid climates in the last 25 years, primarily on occupant preference for thermal comfort in such climates. The issue of overcooled buildings, by design intent or otherwise, is discussed in some detail. Finally, the article has explored some viable adaptive thermal comfort options that show considerable promise for not only improving thermal comfort in tropical buildings but are also energy efficient and could be seen as sustainable solutions. © 2015 John Wiley & Sons A/S.

    This article examines the relation between the adaptive thermal comfort (ATC) model and the Fanger model. The most important data collected were the value ranges of individual parameters in relation to ATC assessment. The ATC model uses a relatively simple indicator of thermal comfort. It treats the desired operational indoor temperature as a measure of thermal comfort in direct comparison to the outdoor temperature. This has the advantage of providing a relatively straightforward and transparent way of assessing occupant comfort. The Fanger model makes use of human thermal equilibrium, and is more flexible and more widely applicable. The results of the comparison show that, in a temperate climate like that of the Netherlands, the Fanger model is fully capable of explaining the results of the ATC model. [Dutch] In dit artikel is de relatie tussen het adaptief thermisch comfort (ATC) model en het Fanger-model nader onderzocht. Hierbij is vooral gekeken naar de ranges van waarden van de individuele parameters in relatie tot de ATC-beoordeling. Her ATC-model maakt gebruik van een minder complexe indicator om een uitspraak te doen over het thermisch comfort. Bij deze aanpak wordt de gewenste operatieve binnentemperatuur, als maat voor her thermisch comfort, direct gerelateerd aan de buitentemperatuur. Een voordeel hiervan is dat op een relatief eenvoudige en inzichtelijke manier een waardering van her comfort kan worden gegeven. Het Fanger-model maakt gebruik van de warmtebalans van de mens en is flexibeler en breder toepasbaar. De resultaten van de vergelijking laten zien dat voor een gematigd klimaat als in Nederland het Fanger-model goed in staat is om de resultaten van het ATC-model te verklaren.

    The research aims to verify the energy performance as well as the indoor comfort of an energy class A+ building, built so that the sum of the heat passive contributions of solar radiation, transmitted through the windows, and the heat generated inside the building, are adeguate to compensate for the envelope loss during the cold season. The building, located in Emilia Romagna (Italy), was built using a wooden structure, an envelope realized using a pinewood sandwich panels (transmittance U = 0.250 W/m2K) and, inside, a wool flax insulation layer and thermal window frame with low-emissivity glass (U = 0524 W/m2K). The building design and construction process has followed the guidelines set by "CasaClima". The building has been modeled in the code of dynamic calculation "Energy Plus" by the Design Builder application and divided it into homogenous thermal zones, characterized by winter indoor temperature set at 20 ° (+ / - 1 °) and summer indoor temperature set at 26 ° (+ / - 1 °). It has modeled: the envelope, as described above, the "free" heat contributions, the air conditioning system, the Mechanical Ventilation system as well as home automation solutions. The air conditioning system is an heat pump, able to guarantee an optimization of energy consumption (in fact, it uses the "free" heat offered by the external environment for conditioning indoor environment). As regards the air recirculation system, it has been used a mechanical ventilation system with internal heat cross-flow exchanger, with an efficiency equal to 50%. The domotic solutions, instead, regard a system for the control of windows external screening using reeds, adjustable as a function of incident solar radiation and a lighting management system adjusted automatically using a dimmer. A so realized building meets the requirement imposed from Italian standard UNI/TS 11300 1, UNI/TS 11300 2 and UNI/TS 11300 3.

    The thermal comfort is one of the most important aspects of the modern vehicles that can influence the safety, the fuel consumption and the pollutions regulation. The objective of this paper is to compare the global and absolute thermal comfort indexes for two vehicles with different distribution air systems inside the car cockpit, one using only front air vents, and the other using both front and rear air vents. The methodology of calculus consists in using the 3D model of the interior vehicle, generally in a CAD format. Then, using a meshing software to create the finite element model of the interior surfaces inside the cockpit and the volume of internal air. Using the obtained finite element geometry, there will be conducted a Theseus FE calculus using the given boundary conditions. The results of the numerical simulation are presented in terms of graphs and figures and also PMV, PPD and DTS thermal comfort indexes. With the obtained results, we will then create the graphs that allows us to evaluate the global and absolute thermal comfort indexes. The results of the evaluation show us that the use of the method allow us to evaluate with a greater accuracy the thermal comfort for the whole vehicle, not only for each passenger, like the standard methods. This shows us that in terms of general and absolute thermal comfort, the vehicle that use front and rear systems is better than the version that use only a front system. The thermal comfort is an important aspect to be taken into account from the beginning of the design stage of a vehicle, by choosing the right air conditioning system. In addition, by using the numerical simulation, we are able to reduce the time needed for preliminary tests and be able to provide the vehicle to the market earlier, at a lower development cost.

    Workspace characteristics affect the perceived comfort level of the operator and uncomfortable working conditions have been found to have a negative impact on productivity and safety. The comfort of the operator is increasingly recognized by manufacturers as a product's added value. Comfort can positively distinguish a product and increase its competitiveness. The concept of comfort is controversial, and a clear operational definition is missing. Nevertheless, it is widely accepted that comfort is a subjective phenomenon that can be evaluated by the final users. In this study, comfort aspects of the tractor workspace interior (i.e., the cab) were investigated. Users with various levels of expertise and two medium-power utility tractors of different brands were used in a 2 x 2 mixed-factorial experimental design. Participants were involved in a dynamic assessment of the cabs, and their opinions about the different workspaces were collected through a questionnaire. Additionally, objective measurements were taken on both tractors, and subjective data were compared with objective data. Results indicate significant differences in terms of the ease of locating and operating the controls (i.e., rear-mounted three-point linkage, hydraulic system, and power take-off), the ease of starting the tractor, the ease exiting the cab, the required level of concentration in executing the tasks, the adequacy of lateral visibility from the driving station, and the level of noise at the operator's position. This article provides guidance for improving the comfort of tractor workspace interiors. Agricultural machinery manufactures would benefit from research results, differentiating themselves from competitors.

    This third article is consecrated to the testimony's analysis of eleven patients having lived an experience of comfort in post-operative phase. The hermeneutic process used is the one proposed by Patricia Benner. However, a innovating aspect is presented in this research. Indeed, the approach centred on the dyad "patient-nurse" allows three types of successive and complementary analyses: (a) the one is directed on experience of operated people, (b) the second is directed on the nurse's living experience and (c) the last is consecrated simultaneously to actors of each dyad. In the frame of the hermeneutic research, this methodological approach is undeniably the strongest point developed by the author, because, it allows an analysis which goes beyond the nursing speech whom the patient "who suffers" is more often the missing subject. Two clinical recommendations end this article.

    Full Text Available The aim of this article is to understand who the Ianfu are via a social-historical and socio-cultural study. I set out to contextualise the reality of the women’s lives as Ianfu and as surviving Ianfu through the inclusion of recollections of former Korean Ianfu and official histories. Who are the Ianfu, what did they do, where did they go, why were they created, and what happened to them? These are the questions that I sought to answer in order to frame the Ianfu experience through a retelling of their past. Furthermore, there are several reasons why Korean women came to comprise the majority of Ianfu which I endeavour to explain in this article.

    Informal settlements, namely slums (or bidonville or favelas) are one of the stronger challenge for urban context in developing countries. The increase of urban population leads to a widespread poverty and critical life conditions for a large segment of population, in particular in Sub-Saharan Africa, where a high percentage of people lives in informal settlements. The problems in slums are multiple: people suffer malnutrition and poor sanitation, flooding or drought, and live in shelters providing no thermal comfort in many days of the year, furthermore scarce and highly polluting energy sources are available. Climate change and an unavoidable heat island effect make these living conditions nearly catastrophic. This paper focuses on the main characters of these slums and on how to what promote the improvement of living conditions with a lean, low cost, low impact, feasible upgrading of the housing or more properly shelters. The subject of the analysis is the Mathare 4A Upgrading Programme in the city of Nairobi, Kenya, one of the highest slum-dwellers growing rate. The technological solutions applied in this context have been verified in a different climate condition such as the city of New Delhi, India where the phenomenon of the slums is significantly burdensome. The analysis of the comfort conditions inside a type housing has been carried out using hourly weather data and dynamic heat transfer simulation, without any HVAC system and striving only natural ventilation. Data about internal temperature and relative humidity conditions have been applied to evaluate the comfort hours using the Predicted Mean Vote method, the adaptive thermal comfort principles and the bioclimatic charts for the two climates in Nairobi and New Delhi. The percentage of hours within the comfort range and the amount of degree-hours exceeding comfort values showed for different upgrading strategies, how it is possible to deeply influence the living conditions by technological and

    Comfort eating, that is eating induced by negative affect, has been a core theme of explanations for overeating and obesity. Psychobiological explanations and processes underlying comfort eating are examined, as well as its prevalence in clinical and nonclinical populations, to consider who may be susceptible, whether certain foods are comforting, and what the implications for treatment may be. Comfort eating may occur in a substantial minority, particularly in women and the obese. Human and animal theories and models of emotional or stress-induced eating show some convergence, and may incorporate genetic predispositions such as impulsivity and reward sensitivity, associated with dopamine dysregulation underlying incentive salience. Comfort eaters show vulnerability to depression, emotional dysregulation and a need to escape negative affect and rumination. During negative affect, they preferentially consume sweet, fatty, energy-dense food, which may confer protection against stress, evidenced by suppression of the hypothalamic-pituitary-adrenal axis response, although activation of the hypothalamic-pituitary-adrenal axis may itself drive appetite for these palatable foods, and the risk of weight gain is increased. Benefits to mood may be transient, but perhaps sufficient to encourage repeated attempts to prolong mood improvement or distract from negative rumination. Cognitive behavioural treatments may be useful, but reliable drug therapy awaits further pharmacogenomic developments.

    A coupled model of human physiology and thermal comfort was developed in Dymola/Modelica. A coupling combines a modified Tanabe model of human physiology and thermal comfort model developed by Zhang. The Coupled model allows predicting the thermal sensation and comfort of both local and overall from local boundary conditions representing ambient and personal factors. The aim of this study was to compare prediction of the Coupled model with the Fiala model prediction and experimental data. Validation data were taken from the literature, mainly from the validation manual of software Theseus-FE [1]. In the paper validation of the model for very light physical activities (1 met) indoor environment with temperatures from 12 °C up to 48 °C is presented. The Coupled model predicts mean skin temperature for cold, neutral and warm environment well. However prediction of core temperature in cold environment is inaccurate and very affected by ambient temperature. Evaluation of thermal comfort in warm environment is supplemented by skin wettedness prediction. The Coupled model is designed for non-uniform and transient environmental conditions; it is also suitable simulation of thermal comfort in vehicles cabins. The usage of the model is limited for very light physical activities up to 1.2 met only.

    Full Text Available Vibration comfort is an important factor affecting the quality of service (QoS of bus. In order to make people involved in supervising bus’s vibration comfort and improve passengers’ riding experience, a novel mode of passenger crowdsourcing is introduced. In this paper, comfort degree of bus vibration is calculated from bus’s vibration signals collected by passengers’ smartphones and sent through WiFi to the Boa web server which shows the vibration comfort on the LCD deployed in bus and maybe trigger alarm lamp when the vibration is beyond the threshold. Three challenges here have been overcome: firstly, space coordinate transformation algorithm is used to solve the constant drift of signals collected; secondly, a low-pass filter is designed to isolate gravity from signals real-timely via limited computing resources; thirdly, an embedded evaluation system is developed according to the calculation procedure specified by criterion ISO 2631-1997. Meanwhile, the model proposed is tested in a practical running environment, the vibration data in whole travel are recorded and analyzed offline. The results show that comfort degree of vibration obtained from the experimental system is identical with the truth, and this mode is proved to be effective.

    Full Text Available This paper discusses the findings of thermal comfort assessment at Malaysian automotive industry. Nine critical workstations were chosen as subjects for the study in order to determine the thermal comfort among workers at Malaysian automotive industry. The human subjects for the study comprises of the operators from tire receiving, dashboard assembly, drum tester, body assembly, seat assembly, door check assembly, stamping workstation, engine sub assembly and paint shop of the factory. The environmental factors such as Wet Bulb Globe Temperature (WBGT, relative humidity, air velocity, illuminance were measured using BABUC A apparatus and Thermal Comfort Measurement equipment. Through questionnaire survey, the demographic data of subjects and their perceptions on thermal comfort at each workstation were assessed based on ISO Standard 7730 and thermal sensation scale using Predicted Mean Vote (PMV. Then, Predicted Percentage of Dissatisfied (PPD is used to estimate the thermal satisfaction of occupants. The results indicated that most of the workstations of the automotive industry are considered as uncomfortable. Tire receiving station is considered having better working environment compared to other stations with lowest PMV index of 1.09 to 1.41 and PPD of 46%. Meanwhile, the engine sub assembly station and paint shop of assembly are considered the worst thermal environment with the PMV index values ranging between 2.1 to 2.9 and PPD values of 81% to 99%. Therefore, these two workstations are considered not comfortable because the thermal sensation scale is warm and almost hot.

    Nursing faculty face increasing instructional demands to keep pace with mounting knowledge and competency requirements for student nurses. In the context of nursing practice, tasks and time pressures detract from the high skill and aptitude expectation of communication. The communication, orientation and opportunity, mindful presence, family, openings, relating, and team (COMFORT) curriculum, an acronym that represents 7 basic nursing communication principles, has been introduced into the communication module of the End-of-Life Nursing Education Consortium, which currently provides the only standardized undergraduate and graduate nurse training in hospice and palliative care. This study examines the potential efficacy of the COMFORT curriculum for everyday communication challenges experienced by members of the Georgia Organization of Nurse Leaders. Participants were prompted to describe communication barriers and then apply an aspect of the COMFORT curriculum to this barrier. Responses revealed primary communication barriers with co-workers and patient/families. Nurses predominantly identified directly correlating components in the COMFORT framework (C-communication, F-family) as solutions to the topics described as barriers. Based on confirmation of extant literature addressing generalist nurse communication challenges, there is support for the inclusion of COMFORT across the nursing curriculum to efficiently and effectively teach communication strategies to nurses.

    Full Text Available The study on outdoor comfort is becoming popular due to the fact that the thermoregulatory model is seen as inadequate in explaining outdoor thermal comfort conditions. Hot-humid region can be said as experiencing a critical environmental condition because of its constantly high temperature and humidity throughout the year. Thus, this study focus on the assessment of thermal comfort of outdoor urban spaces in Kuala Lumpur, Malaysia (3° 9’N and 101° 44’E. Survey on human response towards outdoor thermal comfort in hot-humid climate of Kuala Lumpur, Malaysia was carried out during day time between 0900h to 1800h along with measurement of environmental parameters such as air temperature (°C, wind velocity (m/s, radiant temperature (°C, relative humidity (% and solar radiation (lux. A total of 123 samples were involved in this study which took place within four sites around Kuala Lumpur. Survey results were then correlated with the environmental parameters to further develop the comfort zone for hot-humid outdoor environment specifically for Kuala Lumpur and, generally, for hot-humid regions.

    The purpose of this study was to investigate the subjective perception of overall footwear comfort over a prolonged running session. Ten runners performed two similar sessions consisting of a 13-km trail run (5 laps of 2.6 km) as fast as possible. The overall footwear comfort was evaluated before running and at the end of each lap with a 150-mm visual analogic scale, as well as speed, heart rate and rate of perceived exertion. The results showed that both overall footwear comfort and speed decreased consistently during the run session, and significantly after 44 min of running (i.e. the 3rd lap). It could be hypothesized that the deterioration of overall footwear comfort was explained by mechanical and energetical parameter changes with time and/or fatigue occurring at the whole body, foot and footwear levels. These results justify the use of a prolonged running test for running footwear comfort evaluation. Copyright © 2015 Elsevier Ltd. All rights reserved.

    As is becoming increasingly clear, the human species evolvedin the East African savannah. Details of the precise evolutionary chainremain unresolved however it appears that the process lasted severalmillion years, culminating with the emergence of modern Homo sapiensroughly 200,000 years ago. Following that final evolutionary developmentmodern Homo sapiens relatively quickly populated the entire world.Clearly modern Homo sapiens is a successful, resourceful and adaptablespecies. In the developed societies, modern humans live an existence farremoved from our evolutionary ancestors. As we have learned over the lastcentury, this "new" lifestyle can often result in unintendedconsequences. Clearly, our modern access to food, shelter, transportationand healthcare has resulted in greatly expanded expected lifespan butthis new lifestyle can also result in the emergence of different kinds ofdiseases and health problems. The environment in modern buildings haslittle resemblance to the environment of the savannah. We strive tocreate environments with little temperature, air movement and lightvariation. Building occupants often express great dissatisfaction withthese modern created environments and a significant fraction even developsomething akin to allergies to specific buildings (sick buildingsyndrome). Are the indoor environments we are creating fundamentallyunhealthy -- when examined from an evolutionary perspective?

    Touch is an essential part of caregiving and has been proved to be useful to reduce pain. Nevertheless, little attention has been paid to nurses' perceptions of touch. The aim of this article was to examine the relationship between nurses' feelings of comfort with touch and their well-being at work. A sample of 241 nurses attending a pain management training course completed a questionnaire, including the following measures: Comfort with Touch (CT) scale (task-oriented contact, touch promoting physical comfort, touch providing emotional containment), Maslach Burnout Inventory (MBI; emotional exhaustion, cynicism), and Job Satisfaction. Results of structural equation models showed that touch providing emotional containment was the main predictor of emotional exhaustion. Emotional exhaustion, in turn, was positively related to cynicism and negatively related to job satisfaction. In addition, the direct path from touch providing emotional containment to cynicism was significant. Practical implications of the findings are discussed. © The Author(s) 2014.

    Protection was the basic principle underlying the creation of footwear, once humankind felt the need to protect feet from direct contact with soil, heat, cold and sharp objects. However, this accessory soon acquired cultural, aesthetic, symbolic significance, and apparently it was not related to comfort. This work aims to analyze comfort in women footwear, especially high heels shoe. We intended to understand the emotional relationship of consumers with this type of accessory, as well as to understand to what extent women are willing to give up comfort in favor of aesthetics. For this purpose, a questionnaire was designed, aimed at the female audience in order to understand the relevance of women’s footwear, their daily relationship with shoes, the specificity of heels and the problems caused by it.

    This paper considers the need to define comfort of indoor and outdoor spaces in relation to the daily variations of temperature. A graphical tool is presented, which indicates the daily swings of temperature, shown as a single point on a graph representing the average temperature and the maximum temperature swing. This point can be compared with the comfort zones for different activity levels, such as sedentary activity, sleeping, indoor and outdoor circulation according to the design proposals for different spaces. The graph allows the representation of climatic variables, the definition of comfort zones, the selection of bio climatic design resources and the evaluation of indoor temperatures, measured in actual buildings or obtained from computer simulations. The development of the graph is explained and examples given with special emphasis on the use of thermal mass. (author)

    OBJECTIVE: To evaluate the attitudes of adolescents toward communicating with their doctor about different aspects of their sexuality. METHODS: The present descriptive survey was conducted with the participation of teenagers from four high schools in Sherbrooke, Quebec. In each school, the students of two grade 8 classes (≤14 years of age) and two grade 10 classes (≥15 years of age) anonymously completed a self-administered questionnaire. Permission from the school board and parental consent for every participant was obtained. RESULTS: A total of 387 adolescents completed the self-administered questionnaire. The response rate for the study was 98%. Only 27% of the respondents remembered being questioned by their doctor about sexuality, and 17% of the respondents had already brought up the topic of sexuality themselves with their doctor. More than one-half (57%) of the adolescents reported they would be moderately comfortable to totally comfortable discussing sexuality with their doctor if they felt the need to. Overall, when asked to evaluate their degree of comfort if questioned on specific questions about their sexuality, 73.8% to 99.5% believed they would be moderately to totally comfortable responding. Nevertheless, there was a statistically significant difference between age groups, with the older age group being more comfortable than the younger age group (P<0.001). There was no difference between the level of comfort among boys and girls answering the same questions. Respondents believed that their treating physician should discuss sexuality with them (73.8%) and, in the majority of cases (78%), that he/she should initiate the conversation. CONCLUSION: Regardless of age or sex, teenagers considered themselves to be at ease discussing sexuality with their doctor and found it an important topic best brought up by their practitioner.

  14. Assessing Thermal Comfort Due to a Ventilated Double Window

    2017-10-01

    Building design and its components are the result of a complex process, which should provide pleasant conditions to its inhabitants. Therefore, indoor acceptable comfort is influenced by the architectural design. ISO and ASHRAE standards define thermal comfort as the condition of mind that expresses satisfaction with the thermal environment. The energy demand for heating, beside the building’s physical properties, also depend on human behaviour, like opening or closing windows. Generally, windows are the weakest façade element concerning to thermal performance. A lower thermal resistance allows higher thermal conduction through it. When a window is very hot or cold, and the occupant is very close to it, it may result in thermal discomfort. The functionality of a ventilated double window introduces new physical considerations to a traditional window. In consequence, it is necessary to study the local effect on human comfort in function of the boundary conditions. Wind, solar availability, air temperature and therefore heating and indoor air quality conditions will affect the relationship between this passive system and the indoor environment. In the present paper, the influence of thermal performance and ventilation on human comfort resulting from the construction and geometry solutions is shown, helping to choose the best solution. The presented approach shows that in order to save energy it is possible to reduce the air changes of a room to the minimum, without compromising air quality, enhancing simultaneously local thermal performance and comfort. The results of the study on the effect of two parallel windows with a ventilated channel in the same fenestration on comfort conditions for several different room dimensions, are also presented. As the room dimensions’ rate changes so does the window to floor rate; therefore, under the same climatic conditions and same construction solution, different results are obtained.

  15. Where is the comfort in comfort foods? Mechanisms linking fat signaling, reward, and emotion.

    Science.gov (United States)

    Weltens, N; Zhao, D; Van Oudenhove, L

    2014-03-01

    Food in general, and fatty foods in particular, have obtained intrinsic reward value throughout evolution. This reward value results from an interaction between exteroceptive signals from different sensory modalities, interoceptive hunger/satiety signals from the gastrointestinal tract to the brain, as well as ongoing affective and cognitive processes. Further evidence linking food to emotions stems from folk psychology ('comfort foods') and epidemiological studies demonstrating high comorbidity rates between disorders of food intake, including obesity, and mood disorders such as depression. This review paper aims to give an overview of current knowledge on the neurophysiological mechanisms underlying the link between (fatty) foods, their reward value, and emotional responses to (anticipation of) their intake in humans. Firstly, the influence of exteroceptive sensory signals, including visual, olfactory ('anticipatory food reward'), and gustatory ('consummatory food reward'), on the encoding of reward value in the (ventral) striatum and of subjective pleasantness in the cingulate and orbitofrontal cortex will be discussed. Differences in these pathways and mechanisms between lean and obese subjects will be highlighted. Secondly, recent studies elucidating the mechanisms of purely interoceptive fatty acid-induced signaling from the gastrointestinal tract to the brain, including the role of gut peptides, will be presented. These studies have demonstrated that such subliminal interoceptive stimuli may impact on hedonic circuits in the brain, and thereby influence the subjective and neural responses to negative emotion induction. This suggests that the effect of foods on mood may even occur independently from their exteroceptive sensory properties. © 2014 John Wiley & Sons Ltd.

    The acoustic comfort of classrooms in a Brazilian public school has been evaluated through interviews with 62 teachers and 464 pupils, measurements of background noise, reverberation time, and sound insulation. Acoustic measurements have revealed the poor acoustic quality of the classrooms. Results have shown that teachers and pupils consider the noise generated and the voice of the teacher in neighboring classrooms as the main sources of annoyance inside the classroom. Acoustic simulations resulted in the suggestion of placement of perforated plywood on the ceiling, for reduction in reverberation time and increase in the acoustic comfort of the classrooms.

  17. Assessing swine thermal comfort by image analysis of postural behaviors.

    Science.gov (United States)

    Xin, H

    1999-01-01

    Postural behavior is an integral response of animals to complex environmental factors. Huddling, nearly contacting one another on the side, and spreading are common postural behaviors of group-housed animals undergoing cold, comfortable, and warm/hot sensations, respectively. These postural patterns have been routinely used by animal caretakers to assess thermal comfort of the animals and to make according adjustment on the environmental settings or management schemes. This manual adjustment approach, however, has the inherent limitations of daily discontinuity and inconsistency between caretakers in interpretation of the animal comfort behavior. The goal of this project was to explore a novel, automated image analysis system that would assess the thermal comfort of swine and make proper environmental adjustments to enhance animal wellbeing and production efficiency. This paper describes the progress and on-going work toward the achievement of our proposed goal. The feasibility of classifying the thermal comfort state of young pigs by neural network (NN) analysis of their postural images was first examined. It included exploration of using certain feature selections of the postural behavioral images as the input to a three-layer NN that was trained to classify the corresponding thermal comfort state as being cold, comfortable, or warm. The image feature selections, a critical step for the classification, examined in this study included Fourier coefficient (FC), moment (M), perimeter and area (P&A), and combination of M and P&A of the processed binary postural images. The result was positive, with the combination of M and P&A as the input feature to the NN yielding the highest correct classification rate. Subsequent work included the development of hardware and computational algorithms that enable automatic image segmentation, motion detection, and the selection of the behavioral images suitable for use in the classification. Work is in progress to quantify the

    In this survey, we selected the 11th building of North China Electric Power University as the research object. Data were measured and distributed on each floor. We record the temperature of the classroom, humidity, wind speed, average radiation temperature and other environmental parameters. And we used spare time to create a questionnaire survey of the subjective feeling of the survey, to get everyone in the classroom TSV (hot feeling vote value) and TCV (thermal comfort vote). We analyzed the test data and survey data. What's more we discuss and reflect on the thermal comfort of the human body in different indoor temperature atmospheres.

  1. Living closer to the environment: Housing design concept

    Full Text Available The main idea of this design concept is to strengthen the relationship and understanding between a man - resident and his environment. Residents are separated from the outdoor environment by glazing, which enables constant observation of environment from nearly all points of indoor space, encouraging positive feelings towards external world and understanding of the fragility of biosphere. Care for the environment should become a part of a man's nature and way of living, and it is the people who are expected to become the driving force of positive global changes towards sustainable development. The semisphere-like single family house of 14m in diameter has a multifunctional, multi-layer 'active' facade envelope. The envelope ensures constant visual contact of residents with the whole surroundings, while still providing comfort. The living space of the house reflects natural shapes which are organic rather than rectangular. Such indoor space becomes a part of the environment, rather than being protected, distanced and isolated from it. The house is designed to use solar energy 'passively' by absorption through insulated glazed envelope and 'actively' by outer skin layer on the first floor, made of stripes of flat semi-transparent polycrystalline photovoltaic (PV panels. In addition to its constructive role, the concrete core of the house acts as thermal mass and enables absorption and accumulation of thermal energy. The developed housing concept is applicable in different urban-design units and sets.

    Full Text Available Furniture industry releases annually a large amount of volatile organic compound to the environment due to the use of adhesives, textiles, paints and coating materials. There are some different methods to measure the load of pollutions and the environmental impacts. Life cycle assessment (LCA is one of the best techniques. LCA is a technique in which all environmental impacts related to a product assessed all over its life cycle, from cradle to grave, and ultimately can be used to improve the production process and to prevent unsuitable environmental impacts. In summary, it can be concluded that the use of this technique is the basis for sustainable development and improving social, economic, and environmental indices. This study focused on the collecting of a comprehensive life cycle inventory data for comfortable furniture in two different production processes (B1 and B2 located in Tehran province, and analyzed the environmental impacts during the production process as gate to gate investigation. The results revealed that emissions in production process B1 were higher than that of production process B2. The reason for this is that basic operations such as sawing and frame assembling along with final operation have been done in the same unit for case B1. Textile production and usage, and polyurethane foam were identified as the main hotspots, respectively. Moreover, the results showed that comfortable furniture production process has the highest effects on ecosystem quality, human health, and resources (fossil fuels and mines, respectively.

    2003-09-01

    Full Text Available Humans must acknowledge that the biosphere is the essential support for all living organisms. In order to achieve sustainable use of the planet, humans must proceed beyond egocentrism, ethnocentrism, homocentrism, and biocentrism to ecocentrism. National states, with present policies, are a major obstacle to sustainable use of the planet. However, there is some evidence that the individual has increasing sovereignty at the expense of both nation states and the environment. Still, the primary obstacle to sustainability is inherent in the present system of sovereign nation states. The basic question is how much sovereignty must nation-states and individuals relinquish to preserve the health of Earth's biospheric life support system. A free and open exchange of thoughts on this subject is long overdue. To acheive sustainable use of the planet, humankind must view its identity within the context of the interdependent web of life.

  5. Thermal comfort in Quebec City, Canada: sensitivity analysis of the UTCI and other popular thermal comfort indices in a mid-latitude continental city

    Provençal, Simon; Bergeron, Onil; Leduc, Richard; Barrette, Nathalie

    2016-04-01

    The newly developed Universal Thermal Climate Index (UTCI), along with the physiological equivalent temperature (PET), the humidex (HX) and the wind chill index (WC), was calculated in Quebec City, Canada, a city with a strong seasonal climatic variability, over a 1-year period. The objective of this study is twofold: evaluate the operational benefits of implementing the UTCI for a climate monitoring program of public comfort and health awareness as opposed to relying on traditional and simple indices, and determine whether thermal comfort monitoring specific to dense urban neighborhoods is necessary to adequately fulfill the goals of the program. In order to do so, an analysis is performed to evaluate each of these indices' sensitivity to the meteorological variables that regulate them in different environments. Overall, the UTCI was found to be slightly more sensitive to mean radiant temperature, moderately more sensitive to humidity and much more sensitive to wind speed than the PET. This dynamic changed slightly depending on the environment and the season. In hot weather, the PET was found to be more sensitive to mean radiant temperature and therefore reached high values that could potentially be hazardous more frequently than the UTCI and the HX. In turn, the UTCI's stronger sensitivity to wind speed makes it a superior index to identify potentially hazardous weather in winter compared to the PET and the WC. Adopting the UTCI broadly would be an improvement over the traditionally popular HX and WC indices. The urban environment produced favorable conditions to sustain heat stress conditions, where the indices reached high values more frequently there than in suburban locations, which advocates for weather monitoring specific to denser urban areas.

    Hara, G.

    In the wake of the Great Northern Japan Earthquake and Tsunami, the Japanese people have impressed the world with their strong spirit of cooperation and optimism in the midst of crisis. Japan is now poised to lead the world toward a new economic paradigm and into the age of Public Interest Capitalism which can replace short-termism and shareholder centric capitalism. As the legacy economic and social systems that have dominated advanced countries reach a critical juncture, Japan now stands at the crux of a great opportunity. In the past, Japan's success was driven by the skillful exportation of ``Hard'' (manufactured goods) and ``Soft'' (entertainment/culture) products. In the coming era, the key to Japan's success lies with our ability to leverage our inherent values and disseminate new economic and social systems that trigger innovation, create new industries, and promote a more comfortable, balanced, and sustainable form of global development.

    The Intensive Care Unit is a wonderful place where lives are saved, but it is also a very harsh and unpleasant place where critically ill patients face terrible diseases in very adverse environmental conditions. We must change the design of the ICU and its organization; we must improve privacy, welfare and comfort of patients and families, following their personal and emotional demands. To free up the visiting hours and to improve family care are among our most urging matters, which we should delay no further. We must equip the ICUs with modern monitors and respirators but we must also invest in organization, design, environmental comfort and humanization. We need to redesign clinical practise so that ICU care becomes more agreeable and humane. We should put off this change no longer, since it is an imperative social and professional demand.

    2016-01-01

    Full Text Available Participation in a regular exercise program can improve health status and contribute to an increase in life expectancy. However, exercise accidents like dehydration, exertional heatstroke, syncope, and even sudden death exist. If these accidents can be analyzed or predicted before they happen, it will be beneficial to alleviate or avoid uncomfortable or unacceptable human disease. Therefore, an exercise thermophysiology comfort prediction model is needed. In this paper, coupling the thermal interactions among human body, clothing, and environment (HCE as well as the human body physiological properties, a human thermophysiology regulatory model is designed to enhance the human thermophysiology simulation in the HCE system. Some important thermal and physiological performances can be simulated. According to the simulation results, a human exercise thermophysiology comfort prediction method based on fuzzy inference system is proposed. The experiment results show that there is the same prediction trend between the experiment result and simulation result about thermophysiology comfort. At last, a mobile application platform for human exercise comfort prediction is designed and implemented.

    2018-01-01

    Outdoor comfort is important due to the public spaces functions. Open spaces provide thermal comfort and a pleasant experience to improve the city life quality effectively. The influence of thermal comfort in outdoor activities is a complex problem. This paper presents a literature review and discussion of aspects of physical, psychology, and social behaviour toward outdoor thermal comfort. The valuation is determined not only by the “physical state” but also by the “state of mind”. The assessment is static and objective (i.e., physical and physiological characteristics) that it should be measured. Furthermore, an effective model to provide the knowledge of climatic conditions, as well as the dynamic and subjective aspects (i.e., psychological and social characteristics and behaviour), requires a comprehensive interview and observation. The model will be examined to describe the behaviour that is a reflection of perception and behaviour toward the environment. The adaptation process will constantly evolve so that it becomes a continuous cause between human behaviour and the spatial setting of the formation, which is eventually known as places and not just spaces. This evolutionary process is a civic art form.

    Recent technological advances in wireless communications have enabled easy installation of sensor networks with air conditioning equipment control applications. However, the sensor node power supply, through either power lines or battery power, still presents obstacles to the distribution of the sensing systems. In this study, a novel sensor network, powered by the artificial light, was constructed to achieve wireless power transfer and wireless data communications for thermal comfort measurements. The sensing node integrates an IC-based temperature sensor, a radiation thermometer, a relative humidity sensor, a micro machined flow sensor and a microprocessor for predicting mean vote (PMV) calculation. The 935 MHz band RF module was employed for the wireless data communication with a specific protocol based on a special energy beacon enabled mode capable of achieving zero power consumption during the inactive periods of the nodes. A 5W spotlight, with a dual axis tilt platform, can power the distributed nodes over a distance of up to 5 meters. A special algorithm, the maximum entropy method, was developed to estimate the sensing quantity of climate parameters if the communication module did not receive any response from the distributed nodes within a certain time limit. The light-powered sensor networks were able to gather indoor comfort-sensing index levels in good agreement with the comfort-sensing vote (CSV) preferred by a human being and the experimental results within the environment suggested that the sensing system could be used in air conditioning systems to implement a comfort-optimal control strategy.

    Compression garments are special textile products which apply a pressure on needed body zones for supporting medical, sport or casual activities. Medical bandages are a group of these garments and they have a very common usage for compression effect on legs or arms. These bandages are generally produced by using synthetic raw materials such as polyamide or polyester fibres. Medical bandages are in contact with skin. Even if the synthetic fibres are used, they may cause both comfort and health problems like allergies. Nowadays in textile sector, the expectations of clients include using of natural fibres as far as possible in all garments. Natural fibres have good advantages such as breathability, softness, moisture management ability, non-allergenic and ecologic structure and these characteristics present optimum utilization conditions. In this study, tubular medical bandages were manufactured by using core spun yarns (sheath fibres are selected as tencel, bamboo and cotton, core material is elastane) and their pressure and comfort (air and water vapour permeability) characteristics were investigated. The results indicated that the bandages have good comfort abilities beside adequate pressure values for compression effect. These garments can constitute a new production field for medical bandages with their comfort properties in addition to pressure characteristics.

    Computational simulations allow for a low-cost, reliable means to demonstrate complex and often times inaccessible concepts to undergraduates. However, students without prior computer programming training may find working with code-based simulations to be intimidating and distracting. A series of computational neuroscience labs involving the Hodgkin-Huxley equations, an Integrate-and-Fire model, and a Hopfield Memory network were used in an undergraduate neuroscience laboratory component of an introductory level course. Using short focused surveys before and after each lab, student comfort levels were shown to increase drastically from a majority of students being uncomfortable or with neutral feelings about working in the MATLAB environment to a vast majority of students being comfortable working in the environment. Though change was reported within each lab, a series of labs was necessary in order to establish a lasting high level of comfort. Comfort working with code is important as a first step in acquiring computational skills that are required to address many questions within neuroscience.

    This article presents the results from thermal comfort survey carried out in classrooms over two different seasons in Maceio, Brazil. The secondary data were collected from thermal comfort field study conducted in naturally ventilated classrooms. Objective and subjective parameters were explored to evaluate thermal comfort conditions. The potential effect of air movement on subjects' vote under neutrality was evaluated. Overall, the indoor climate of the surveyed location was classified warm and humid. Conflicting results were depicted when analyzing the effect of air movements on subjects' vote. The mean air temperature for subjects feeling hot was found to be lower than those feeling warm. A reasonable approach to tackle these two unpredictable results was suggested. Correlation matrix between selected thermal comfort variables was developed. Globe temperature recorded the highest correlation with subjects' response on ASHRAE seven-point scale. The correlation was significant at the 0.01 level. On the other hand, the correlation between air movement and subjects' response on ASHRAE seven-point scale was weak but significant. Further field studies on the current topic were recommended.

    An air conditioner (AC) consumes a significant proportion of the total household power consumption. Primarily used in developing countries, decentralised AC has an inbuilt thermostat to cool the room to a temperature, manually set by the users. However, residents are incapable of specifying their goal through these thermostats - maximise their comfort or save AC energy. State-of-the-art portable thermostats emulate AC remotes and assist occupants in remotely changing the thermostat temperature, through their smartphones. We propose extending such thermostats to portable+ by adding a Comfort-Energy Trade-off (CET) knob, realised through an optimisation framework to allow users to balance their comfort and the savings without worrying about the right set temperature. Analysis based on real data, collected from a controlled experiment (across two rooms for two weeks) and an in-situ deployment (across five rooms for three months), indicates that portable+ thermostats can reduce residents’ discomfort by 23% (CET selection for maximal comfort) and save 26% energy when CET is set for maximising savings.

    Thermophysiological comfort applies to the way in which clothing lets through or retains heat and moisture and helps the body retain heat balance in rest position or at various levels of activities. In this paper, the principles of sensory analysis are used to define the protocol of new method for the evaluation of thermophysiological comfort wearing different garments. Sensory analysis was chosen because as a scientific discipline that applies experiment principles using human senses is used for the evaluation of consumer goods. Test protocol using assessors described in this paper consists of the following steps: defining the interview content, finding potential assessors and making an interview, creating a survey, conducting a survey, group discussion, test and group discussion scoring, selection of assessors, assessment preparation and subjective assessment. On average the most distinctive increase in the sensation of warmth was recorded for the polyester clothing ensemble, and the lowest one for the cotton clothing ensemble. Concerning the average grades of comfort given by assesors, the most comfortable clothing ensemble is the one made of viscose. It was also found out that the method is especially suitable if a representative group of assessors is formed.

    Full Text Available Thermal comfort is one of ergonomics factors that can create a significant impact to workers performance. For a better thermal comfort, several environment factors (air temperature, wind speed and relative humidity should be considered in this research. The object of the study is a building for converting process of plastics manufacturing industry located in Malang, Indonesia. The maximum air temperature inside the building can reach as high as 36°C. The result of this study shows that heat stress is dominantly caused by heat source from machine and wall building. The computational fluid dynamics (CFD simulation is used to show the air characteristic through inside the building. By using the CFD simulation, some scenarios of solution are successfully presented. Employees thermal comfort was investigated based on predicted mean vote model (PMV and predicted percentage of dissatisfied model (PPD. Existing condition gives PMV in range from 1.83 to 2.82 and PPD in range from 68.9 to 98%. Meanwhile, modification of ventilation and replacing ceiling material from clear glass into reflective clear glass gave significant impact to reduce PMV into range from 1.63 to 2.18 and PPD into range from 58.2 to 84.2%. In sort, new design converting building process has more comfortable for workers.

    Subjective comfort of footwear is important for shoe and orthosis design. This study compared shoe preferences between walking and running, using subjective comfort as an outcome tool. Forty-one participants walked and ran 20 times each along a runway in three types of footwear (cushioning, lightweight, and stability) and chose the model that they preferred most for walking and running separately based on subjective comfort. More participants preferred the cushioning model (walking, 34%; running, 41%) or the lightweight model (walking, 44%; running, 41%) over the stability model (walking, 22%; running, 17%). χ² tests revealed no differences between walking and running, runners and nonrunners, and lighter and heavier individuals. Women were more likely (odds ratio = 4.09) to prefer the lightweight model, whereas men preferred the cushioning (odds ratio = 2.05) and stability (odds ratio = 3.19) models. Most participants (71%) chose the same model for both activities. Shoe preference varies among individuals and is influenced by sex. Most people feel comfortable walking and running in the same shoe model.

    Full Text Available Malaysia is a tropical country and has rich tradition of vernacular architecture. Traditional vernacular houses (Kampung Houses are proved to be environmentally sustainable, and the neighborhoods containing these houses traditionally showed the potential to build up community bonding inside the neighborhood, and hence social sustainable. But the future of this social sustainability might be in danger. Malaysia is currently rapidly urbanizing, and now 72 percent people live in urban areas. These urban areas are often very close to the Kampungs, and local people often move to urban houses. The urban housings lack the traditional pattern of community bonding. With every respect to the environmental sustainability of Kampung houses, and recognizing the rich tradition of social sustainability of Kampung neighborhoods as a whole, the question is whether Kampung communities will remain socially sustainable in future. This study took an ethnographic method, and interviewed existing Kampung dwellers of three different generations for their view on why people should or should not live in Kampungs in future. After qualitative analysis, several interesting findings evolved through grounded theories, and the study tried to suggest strategies on how to bridge this increasing gap between living harmoniously both in the rural and urban setup for the future generations in Malaysia. Data showed that though all generations acknowledged the benefits of living in Kampungs, better job opportunity motivates the young generation to leave Kampungs. It concludes that Kampungs still have the power to sustain the modern society with its powerful social potentials, but needs to be nurtured with modern facilities.

  12. Driving Rhythm Method for Driving Comfort Analysis on Rural Highways

    Directory of Open Access Journals (Sweden)

    2017-08-01

    Full Text Available Driving comfort is of great significance for rural highways, since the variation characteristics of driving speed are comparatively complex on rural highways. Earlier studies about driving comfort were usually based on the actual geometric road alignments and automobiles, without considering the driver’s visual perception. However, some scholars have shown that there is a discrepancy between actual and perceived geometric alignments, especially on rural highways. Moreover, few studies focus on rural highways. Therefore, in this paper the driver’s visual lane model was established based on the Catmull-Rom spline, in order to describe the driver’s visual perception of rural highways. The real vehicle experiment was conducted on 100 km rural highways in Tibet. The driving rhythm was presented to signify the information during the driving process. Shape parameters of the driver’s visual lane model were chosen as input variables to predict the driving rhythm by BP neural network. Wavelet transform was used to explore which part of the driving rhythm is related to the driving comfort. Then the probabilities of good, fair and bad driving comfort can be calculated by wavelets of the driving rhythm. This work not only provides a new perspective into driving comfort analysis and quantifies the driver’s visual perception, but also pays attention to the unique characteristics of rural highways.

    Whether a journey is pleasant or not usually depends on the climatic conditions which permit to perform outdoor activities. The perception of climatic conditions, determined by physiological and psychological factors, can vary according to different adaptation phenomena related to the person involved and the weather conditions of the place where they live. Studying the bioclimatology of a country characterized by a high flux of tourism, as e.g. Italy, can provide some important information about where and when is it better to visit a place. Some differences have to be specified though, like the local tourism, which is used to that type of climate, and international tourism, which is formed by people coming from countries with different types of climates. Therefore this paper examined the climatic conditions and outdoor thermal comfort through the Mediterranean Outdoor Comfort Index (MOCI) for local tourism and through the predicted mean vote (PMV) for international tourism. The cities examined were three (Venice, Rome and Palermo located in the North, Centre and South of Italy, respectively), where average information were collected every week for an entire year. Finally, a map of the entire Italian territory reporting the seasonal average values of these indexes was also reported.

    In the current environment of increased emphasis on sustainable transport, there is manifold increase in the use of bicycles for urban transport. One concern which might restrict the use is the ride comfort and fatigue. There has been limited research in addressing the difficulty in bicycle ride comfort quantification. The current study aims to develop a methodology to quantify bicycle discomfort so that performance of bicycles constructed from bamboo and aluminium alloy can be compared. Experimentally obtained frequency response functions are used to establish a relation between the road input and the seat and rider response. A bicycle track input profile based on standard road profiles is created so as to estimate the acceleration responses. The whole-body-vibration frequency weighting is applied to quantify the perception of vibration intensity so that eventual discomfort ranking can be obtained. The measured frequency response functions provide an insight into the effect of frame dynamics on the overall resonant behaviour of the bicycles. The beneficial effect of frame compliance and damping on lower modes of vibration is very clear in the case of bamboo frame, in turn affecting seat and rider response. In the bamboo frame, because of multiple resonances, the frequency response of the handlebar is smaller at higher frequencies suggesting effective isolation. Further improvements may have come from the joints made from natural composites. Overall, based on the comparative analysis and the methodology developed, bamboo frame shows significant improvement in ride comfort performance compared with the aluminium frame.

    The Independent Schools Foundation Academy (ISF) in Hong Kong established a sustainability policy in 2015, which explicitly states, "an experimentally integrated, environmentally and ethically sustainable system of science education and conservation practices based on the 2012 Jeju Declaration of the World Conservation Congress will be implemented through the school". ISF Academy is a private Chinese bilingual school in Hong Kong serving over 1500 students K-12, following the framework and curriculum of the International Baccalaureate Organization (IBO). The strategy behind the implementation of this policy includes: development of a scientific sustainable curriculum that is age appropriate; establish a culture of sustainability within the ISF community and beyond to the wider HK community; install sustainable infrastructure that allows students to learn; and learn first hand sustainable living practices. It is well understood that solutions to the environmental challenges facing Hong Kong and our planet will require multiple disciplines. The current sustainability programs at ISF include: a) a whole school aerobic food waste composting system and organic farming, b) energy consumption monitoring of existing buildings, c) upcoming installation of an air pollution monitoring equipment that will correlate with the AQHI data collected by the Hong Kong government, d) a Renewable Energy Education Center (REEC) that will teach students about RE and also produce solar energy for classroom consumption, and e) student lead environmental group that manages the paper and used cooking oil recycling on campus. The Shuyuan Science and Sustainability faculty work closely with classroom teachers to ensure that the above mentioned projects are incorporated into the curriculum throughout the school. Interdisciplinary units (IDU) of study are being developed that encourage faculty and students to work across subject areas. Projects include Personal Projects, Extended Essays

    2010-12-01

    Vulnerable populations, specifically migrant farm workers and persons experiencing homelessness, are often at an increased risk for foot infections. This risk is related to their working and living conditions, socioeconomic status, limited access to health care, frequent exposure to wet environments, limited access to clean and dry socks and shoes, bathing or laundry facilities, and daily routines that requires them to be on their feet for long periods of time. After years of caring for these populations and hundreds of clinical encounters, an evidence-based, effective method of foot care that incorporates intentional comfort touch has been developed. This article describes methods for mitigating the severity of fungal growth, decreasing the risk of secondary infections, and improving skin integrity by manipulating the micro-environment of the patients' feet. This includes fundamental aspects of hygiene as described by Florence Nightingale's Environmental Theory that suggests that direct sunlight, fresh air, and cleanliness improves health.

    To know the ways and means of comfort perceived by the older adults hospitalized in a medical service. Ethnographic study with a qualitative approach. We conducted semi-structured interviews with 22 older adults and participant observation of care situations. The ways and means of providing comfort are centered on strategies for promoting care mobilized by nurses and recognized by patients(clarifying/informing, positive interaction/communication, music therapy, touch, smile, unconditional presence, empathy/proximity relationship, integrating the older adult or the family as partner in the care, relief of discomfort through massage/mobilization/therapy) and on particular moments of comfort (the first contact, the moment of personal hygiene, and the visit of the family), which constitute the foundation of care/comfort. Geriatric care is built on the relationship that is established and complete with meaning, and is based on the meeting/interaction between the actors under the influence of the context in which they are inserted. The different ways and means of providing comfort aim to facilitate/increase care, relieve discomfort and/or invest in potential comfort.

    2015-01-01

    Full Text Available This paper presents an improved generalized force model (IGFM that considers the driver’s comfortable driving behavior. Through theoretical analysis, we propose the calculation methods of comfortable driving distance and velocity. Then the stability condition of the model is obtained by the linear stability analysis. The problems of the unrealistic acceleration of the leading car existing in the previous models were solved. Furthermore, the simulation results show that IGFM can predict correct delay time of car motion and kinematic wave speed at jam density, and it can exactly describe the driver’s behavior under an urgent case, where no collision occurs. The dynamic properties of IGFM also indicate that stability has improved compared to the generalized force model.

    This work focussed on thermal comfort as the basis to control indoor conditions. Its objective is a method to determine thermal preferences of office occupants. The method is based on detection of thermal events. They occur when indoor conditions are under control of occupants. Thermal events are associated with the use of local heating/cooling sources which have user-adjustable settings. The detection is based on Fourier analysis of indoor temperature time series. The relevant data is collected by temperature sensor. We achieved thermal events recognition rate of 86 %. Conditions when indoor conditions were beyond control were detected with 95.6 % success rate. Using experimental data it was demonstrated that the method allows to reproduce key elements of temperature statistics associated with conditions when occupants are in control of thermal comfort.

    Full Text Available The well being of people needs to be a priority in the modern world. In that respect, vibration cannot be one more cause of stress. Besides that, vibration comfort is very important, since high levels may cause health or even tasks' accomplishment problems. Several parameters may influence the levels of vibration a human being supports. Among them, one can mention the influence of gender, age, corporeal mass index (CMI, temperature, humor, anxiety, hearing, posture, vision, etc. The first three parameters mentioned were already investigated in previous studies undertaken by GRAVI (Group of Acoustics and Vibration researchers. In this paper, the influence of vision is evaluated. The main objective with this series of tests performed is to try to quantify in a future the influence of each parameter in a global vibration comfort level. Conclusions are presented for the parameter investigated.

    1996-06-01

    This paper proposes a comfortable visual display terminal (VDT) workstation layout based on an analysis of ocular surface area (OSA). A large OSA induces eye irritation and eye fatigue because the eye surface is highly sensitive to various stimuli. The authors considered that OSA must be one of the useful indices of visual ergonomics and applied it to evaluate VDT workstation layout. Each subject was asked to perform a word processing task using four different VDT workstation layouts. It was found that the main factor affecting OSA was not cathode ray tube (CRT) height itself but the distance between the CRT and keyboard. Thus the following workstation layout is recommended to realize comfortable VDT operation: (1) the desk height should be adjusted to the user's height; and (2) the CRT display should be set closer to the keyboard to provide a smaller OSA.

    This study investigated whether Black students' social comfort with Whites, termed outgroup comfort (OC), predicted outcomes related to academics and mental health. Surveys administered to Black college students near the beginning and end of their first year showed OC measured in the fall predicted outcomes assessed in the spring, including contact with other races, academic concerns among men, and psychological well-being among women. A subsample selected on the basis of high or low OC scores participated in two weeks of experience sampling, revealing students high in OC reported less state anxiety than those low in OC when in academic settings; in nonacademic settings, anxiety did not differ by OC. System-justifying ideology favoring the outgroup was controlled, thus OC is distinct from internalized oppression. Results are discussed in relation to gender differences in racial identity and college student development. 2008 APA

    Contact lenses are associated with discomfort during wear. This may be the result of stimulation of the ocular surface and production of pro-inflammatory mediators which are then released into the tears. This study examined changes in the concentration in tears of arachidonic acid metabolites (AAM) prostaglandins, cysteinyl leukotrienes, and resolvin-D1, as well as histamine in a general contact lens population in the morning and evening. Tears were collected twice a day (morning and evening) for up to 10 days on two different occasions (with and without contact lens wear) from 30 experienced contact lens wearers for analysis of AAM and a separate group (N = 33) for analysis of histamine. Ocular comfort was rated subjectively on an ordinal scale at each time of tear collection. Tears were analyzed using commercial immunoassay-based kits. Statistical analysis was performed using linear mixed model test. Ocular comfort decreased from morning to evening with and without contact lenses (p = 0.001), and the difference in comfort in the evening was greater with contact lens wear (80.9 ± 16.2 vs. 75.5 ± 16.8; p = 0.008). The total concentration of PGs (10.7 ± 10.8 ng/ml), cysteinyl leukotrienes (8.7 ± 0.38 ng/ml), resolvin-D1 (1.6 ± 0.5 ng/ml), or histamine 13.8 ± 10.4 ng/ml) did not change during the day or during contact lens wear (p > 0.05). Prostaglandins, cysteinyl leukotrienes, resolvin-D1, or histamine concentrations did not alter in relation to changes in comfort of the eye during the day or during contact lens wear. These results suggest that release of these mediators is not responsible for contact lens discomfort.

    The effects of adrenal corticosteroids on subsequent adrenocorticotropin secretion are complex. Acutely (within hours), glucocorticoids (GCs) directly inhibit further activity in the hypothalamo-pituitary-adrenal axis, but the chronic actions (across days) of these steroids on brain are directly excitatory. Chronically high concentrations of GCs act in three ways that are functionally congruent. (i) GCs increase the expression of corticotropin-releasing factor (CRF) mRNA in the central nucleus of the amygdala, a critical node in the emotional brain. CRF enables recruitment of a chronic stress-response network. (ii) GCs increase the salience of pleasurable or compulsive activities (ingesting sucrose, fat, and drugs, or wheel-running). This motivates ingestion of "comfort food." (iii) GCs act systemically to increase abdominal fat depots. This allows an increased signal of abdominal energy stores to inhibit catecholamines in the brainstem and CRF expression in hypothalamic neurons regulating adrenocorticotropin. Chronic stress, together with high GC concentrations, usually decreases body weight gain in rats; by contrast, in stressed or depressed humans chronic stress induces either increased comfort food intake and body weight gain or decreased intake and body weight loss. Comfort food ingestion that produces abdominal obesity, decreases CRF mRNA in the hypothalamus of rats. Depressed people who overeat have decreased cerebrospinal CRF, catecholamine concentrations, and hypothalamo-pituitary-adrenal activity. We propose that people eat comfort food in an attempt to reduce the activity in the chronic stress-response network with its attendant anxiety. These mechanisms, determined in rats, may explain some of the epidemic of obesity occurring in our society.

    The well being of people needs to be a priority in the modern world. In that respect, vibration cannot be one more cause of stress. Besides that, vibration comfort is very important, since high levels may cause health or even tasks' accomplishment problems. Several parameters may influence the levels of vibration a human being supports. Among them, one can mention the influence of gender, age, corporeal mass index (CMI), temperature, humor, anxiety, hearing, posture, vision, etc. The first th...

    2008-10-01

    Full Text Available Recent technological advances in wireless communications have enabled easy installation of sensor networks with air conditioning equipment control applications. However, the sensor node power supply, through either power lines or battery power, still presents obstacles to the distribution of the sensing systems. In this study, a novel sensor network, powered by the artificial light, was constructed to achieve wireless power transfer and wireless data communications for thermal comfort measurements. The sensing node integrates an IC-based temperature sensor, a radiation thermometer, a relative humidity sensor, a micro machined flow sensor and a microprocessor for predicting mean vote (PMV calculation. The 935 MHz band RF module was employed for the wireless data communication with a specific protocol based on a special energy beacon enabled mode capable of achieving zero power consumption during the inactive periods of the nodes. A 5W spotlight, with a dual axis tilt platform, can power the distributed nodes over a distance of up to 5 meters. A special algorithm, the maximum entropy method, was developed to estimate the sensing quantity of climate parameters if the communication module did not receive any response from the distributed nodes within a certain time limit. The light-powered sensor networks were able to gather indoor comfort-sensing index levels in good agreement with the comfort-sensing vote (CSV preferred by a human being and the experimental results within the environment suggested that the sensing system could be used in air conditioning systems to implement a comfort-optimal control strategy.

  20. Development of a method for rating climate seat comfort

    The comfort aspect in the vehicle interior is becoming increasingly important. A high comfort level offers the driver a good and secure feeling and has a strong influence on passive traffic safety. One important part of comfort is the climate aspect, especially the microclimate that emerges between passenger and seat. In this research, different combinations of typical seat materials are used. Fourteen woven and knitted fabrics and eight leathers and its substitutes for the face fabric layer, one foam, one non-woven and one 3D spacer for the plus pad layer and for the support layer three foam types with variations in structure and raw material as well as one rubber hair structure were investigated. To characterise this sample set by thermo-physiological aspects (e.g. water vapour resistance Ret, thermal resistance Rct, buffering capacity of water vapour Fd) regular and modified sweating guarded hotplates were used according to DIN EN ISO 11092. The results of the material characterisation confirm the common knowledge that seat covers out of textiles have better water vapour resistance values than leathers and its substitutes. Subject trials in a driving simulator were executed to rate the subjective sensation while driving in a vehicle seat. With a thermal, sweating Manikin (Newton Type, Thermetrics) objective product measurements were carried out on the same seat. Indeed the subject trials show that every test subject has his or her own subjective perception concerning the climate comfort. The results of the subject trials offered the parameters for the Newton measuring method. Respectively the sweating rate, sit-in procedure, ambient conditions and sensor positions on and between the seat layers must be comparable with the subject trials. By taking care of all these parameters it is possible to get repeatable and reliable results with the Newton Manikin. The subjective feelings of the test subjects, concerning the microclimate between seat and passenger, provide

    The aim of the present methodological descriptive study was to test the validity and reliability of the COMFORT scale. The study was conducted at a pediatric critical care unit at a university hospital between February 2009 and June 2010. Study sample included 84 pediatric patients (n=37) receiving mechanical ventilation. Data were collected via child information form, COMFORT scale, and visual analog scale (VAS). Having been assured of the language and context validity of the scale, researchers conducted reliability tests (Cronbach's alpha coefficient, item analysis), inter- and intra-observer reliability tests, and correlation analyses based on the data obtained during their own observations. Cronbach's alpha coefficient was 0.77. Results of the item analysis indicated that item-total correlations were satisfactorily high. Significance of inter-observer agreement was analyzed for each item, and it was found that weighted kappa values varied between 0.703 and 0.888. Convergent validity tests demonstrated a positive strong correlation between COMFORT scale scores of the primary researcher and the assistant researchers (r= 0.961, pVAS (r= 0.775, pvalid and reliable method of measuring sedation levels of children receiving mechanical ventilation and being sedated in a pediatric critical care unit.

    2017-12-01

    This paper presents results to thermal comfort and environment quality questions in 21 school building rooms. Results show that about 80% of the occupants expressed satisfaction with their thermal comfort in only 11% of the buildings surveyed. Air quality scores were somewhat higher, with 26% of buildings having 80% or occupant satisfaction. With respect to thermal comfort and air quality performance goals set out by standards, most buildings appear to be falling far short. Occupant surveys offer a means to systematically measure this performance, and also to provide diagnostic information for building designers and operators. The odours from building materials as well as human odours were studied by field measurement. The odour intensity and indoor air acceptability were assessed by a sensory panel. The concentrations of total volatile organic compounds and carbon dioxide were measured. The odours from occupancy and building materials were studied under different air change rate. The case study of indoor air acceptability concerning to indoor odours and its effect on perceived air quality are also presented in this paper.

    Full Text Available The use of local natural materials in order to reduce the environmental negative impact of buildings has become common practice in recent years; such buildings are to be found in all regions of the planet. The high level of thermal protection provided by the envelope elements made from natural materials such as straw bale insulation, hemp insulation or sheep wool, and their lack of thermal massiveness require a more complex analysis on their ability to keep interior comfort without accentuated variations. This paper proposes a comparative analysis between different solutions for a residential building located near a Romanian city, Cluj-Napoca. The elements of the building envelope are designed in three alternative solutions, using as substitute to classical solutions (concrete and polystyrene, masonry and polystyrene, straw bales and rammed earth for enclosing elements. For this purpose there are conducted numerical simulations of heat and mass transfer, using a mathematical model that allows the analysis of indoor comfort, by comparing both objective factors (air temperature, operative temperature and relative humidity and subjective factors, which are needed to define interior thermal comfort indices PPD and PMV. Finally, a set of conclusions are presented and future research directions are drawn.

    Recent increased usage of stereo displays has been accompanied by public concern about potential adverse effects associated with prolonged viewing of stereo imagery. There are numerous potential sources of adverse effects, but we focused on how vergence–accommodation conflicts in stereo displays affect visual discomfort and fatigue. In one experiment, we examined the effect of viewing distance on discomfort and fatigue. We found that conflicts of a given dioptric value were slightly less comfortable at far than at near distance. In a second experiment, we examined the effect of the sign of the vergence–accommodation conflict on discomfort and fatigue. We found that negative conflicts (stereo content behind the screen) are less comfortable at far distances and that positive conflicts (content in front of screen) are less comfortable at near distances. In a third experiment, we measured phoria and the zone of clear single binocular vision, which are clinical measurements commonly associated with correcting refractive error. Those measurements predicted susceptibility to discomfort in the first two experiments. We discuss the relevance of these findings for a wide variety of situations including the viewing of mobile devices, desktop displays, television, and cinema. PMID:21778252

  6. Evaluation of the thermal comfort of ceramic floor tiles

    Directory of Open Access Journals (Sweden)

    Carmeane Effting

    2007-09-01

    Full Text Available In places where people are bare feet, the thermal sensation of cold or hot depends on the environmental conditions and material properties including its microstructure and crustiness surface. The uncomforting can be characterized by heated floor surfaces in external environments which are exposed to sun radiation (swimming polls areas or by cold floor surfaces in internal environments (bed rooms, path rooms. The property named thermal effusivity which defines the interface temperature when two semi-infinite solids are putted in perfect contact. The introduction of the crustiness surface on the ceramic tiles interferes in the contact temperature and also it can be a strategy to obtain ceramic tiles more comfortable. Materials with low conductivities and densities can be obtained by porous inclusion are due particularly to the processing conditions usually employed. However, the presence of pores generally involves low mechanical strength. This work has the objective to evaluate the thermal comfort of ceramics floor obtained by incorporation of refractory raw materials (residue of the polishing of the porcelanato in industrial atomized ceramic powder, through the thermal and mechanical properties. The theoretical and experimental results show that the porosity and crustiness surface increases; there is sensitive improvement in the comfort by contact.

    We propose watch-type sweat rate sensors capable of automatic natural ventilation by integrating miniaturized thermo-pneumatic actuators, and experimentally verify their performances and applicability. Previous sensors using natural ventilation require manual ventilation process or high-power bulky thermo-pneumatic actuators to lift sweat rate detection chambers above skin for continuous measurement. The proposed watch-type sweat rate sensors reduce operation power by minimizing expansion fluid volume to 0.4 ml through heat circuit modeling. The proposed sensors reduce operation power to 12.8% and weight to 47.6% compared to previous portable sensors, operating for 4 hours at 6 V batteries. Human experiment for thermal comfort monitoring is performed by using the proposed sensors having sensitivity of 0.039 (pF/s)/(g/m 2 h) and linearity of 97.9% in human sweat rate range. Average sweat rate difference for each thermal status measured in three subjects shows (32.06 ± 27.19) g/m 2 h in thermal statuses including 'comfortable', 'slightly warm', 'warm', and 'hot'. The proposed sensors thereby can discriminate and compare four stages of thermal status. Sweat rate measurement error of the proposed sensors is less than 10% under air velocity of 1.5 m/s corresponding to human walking speed. The proposed sensors are applicable for wearable and portable use, having potentials for daily thermal comfort monitoring applications.

  8. Comfortable synchronization of cyclic drawing movements with a metronome.

    2011-02-01

    Continuous circle drawing is considered a paragon of emergent timing, whereas the timing of finger tapping is said to be event-based. Synchronization with a metronome, however, must to some extent be event-based for both types of movement. Because the target events in the movement trajectory are more poorly defined in circle drawing than in tapping, circle drawing shows more variable asynchronies with a metronome than does tapping. One factor that may have contributed to high variability in past studies is that circle size, drawing direction, and target point were prescribed and perhaps outside the comfort range. In the present study, participants were free to choose most comfortable settings of these parameters for two continuously drawn shapes, circles and infinity signs, while synchronizing with a regular or intermittently perturbed metronome at four different tempi. Results showed that preferred circle sizes were generally smaller than in previous studies but tended to increase as tempo decreased. Synchronization results were similar for circles and infinity signs, and similar to earlier results for circles drawn within a fixed template (Repp & Steinman, 2010). Comparison with tapping data still showed drawing to exhibit much greater variability and persistence of asynchronies as well as slower phase correction in response to phase shifts in the metronome. With comfort level ruled out as a factor, these differences can now be attributed more confidently to differences in event definition and/or movement dynamics. Copyright © 2010 Elsevier B.V.

    2017-01-01

    Full Text Available Thermal comfort sensation can be predicted in the most exact way based on Fanger’s predicted mean vote (PMV model. This evaluation method takes all the six influencing factors into consideration: air temperature and humidity, air velocity, mean radiant temperature of surrounding surfaces, clothing insulation, and occupants’ activities. Fanger’s PMV method was developed for temperate climate and European people, with the participation of university students as subjects. Many researchers had investigated its validity in different geographic locations (i. e. climatic conditions, people and under non-laboratory circumstances. The results were summarised by van Hoof which had been published in the scientific references. The articles gave us the idea to elaborate the former measurement results. During the last decades thermal comfort was evaluated by our research team using subjective scientific questionnaires and applying the objective Fanger’s model in several office buildings in Hungary. The relation between the PMV and actual mean vote values were analysed based on these results. Investigations were carried out under steady-state conditions in winter time. We performed objective thermal comfort evaluations based on instrumental measurements using the PMV theory. Parallel to this we assessed the subjective thermal sensation using scientific questionnaires. The mathematical relationship between the actual mean vote and PMV was defined according to the evaluated thermal environment: AMV = PMV + 0.275, (arg. –1.7 ≤ PMV ≤ +0.5.

  19. ComfortPower - System improvements and long-term evaluation

    Energy Technology Data Exchange (ETDEWEB)

    Silversand, Fredrik [Catator AB, Lund (Sweden)

    2011-11-15

    Catator has previously developed a novel heating system abbreviated ComfortPower in a RandD-programme supported by Catator, Swedish Gas Centre (SGC), Swedish Defence Materiel Administration (FMV), Skanska, Nibe and Alfa Laval. The ComfortPower unit comprises a multi fuel reformer system tied to a high-temperature polymer electrolyte fuel cell (HT-PEM) and a heat pump system. Since the residual heat from the fuel cell system can be utilized in a very effective way, it is possible to reach high thermal efficiencies. Indeed, the thermal efficiency in the unit has previously been shown to reach values as high as 175 - 200 % based on the lower heating value of the fuel. In addition to heat, ComfortPower can supply comfort cooling and surplus electricity. This project phase has focused on the following elements: 1. System improvements to further enhance the efficiency with existing fuel cell (HT-PEM). 2. System simplifications (e.g. DC-compressor system) to manage issues with start-up currents. 3. Tests with biogas qualities (various levels of CO{sub 2}) and biogas/air. 4. Long-term test with biogas quality (upgraded biogas). 5. Additional tests with liquid fuels (alcohols and diesel). 6. Map the need for cooling and heating in various applications. 7. Investigate how ComfortPower can reduce the primary energy consumption and reduce the environmental impact. 8. Study the possibility with a SOFC-based system with internal reforming. It was found that the Optiformer technology can be used to derive a suitable reformate gas for the HT-PEM unit from a wide range of fuels. Even if operation with fuel gases is the natural choice in most cases, it is possible also to use alcohols and other liquid fuels (e.g. in Campus applications). The heat pump system was equipped with a 24 V DC-compressor provided by Nibe. The compressor could be directly powered by the accumulator system and start-up currents, harmful to the inverter, could be avoided. Some improvements were made on the

    Pressure-related skin lesions on the digits are a significant cause of discomfort. Most foot pain related to ill-fitting shoes occurs in the forefoot and digital areas. Pain has been associated with poor shoe fit, reduced toe box volume, as well as contour and shape of the shoe Off-the-shelf medical-grade footwear is designed as an intervention for chronic lesions on the digits. These shoes are designed with a flexible neoprene fabric upper that is thought to reduce pressure on the forefoot and reduce discomfort associated with ill-fitting shoes. The aim of this study was to investigate the effect of an off-the-shelf, medical-grade shoe on dorsal digital pressure and perceived comfort when compared to participant's own preferred shoe. Thirty participants (18 females, 12 males) scored their perceived comfort whilst wearing each footwear style using a visual analog comfort scale. Dorsal digital and interdigital pressures were measured in using the WalkinSense® in-shoe pressure system. Sensors were placed on predetermined anatomical landmarks on the digits. Participants were randomly assigned the test shoe and their own shoe. Once wearing the shoe, the participants walked across a 6 m walkway and pressure data from each sensor was collected and processed to obtain peak pressure, time to peak pressure and contact time. Participants scored the test shoe with higher comfort points than their own footwear. Overall peak pressure, pressure time integral and contact time decreased, whilst the time taken to reach peak pressure increased across all anatomical landmarks whilst wearing the test shoe. Statistically significant changes were observed for all of the measured variables relating to pressure on the medial border of the first metatarsophalangeal joint. The test shoe provided greater comfort and reduced the amount of pressure on the forefoot. The medical-grade footwear therefore, is a viable alternative to custom made prescription footwear and is more suitable than a

    2015-06-01

    Full Text Available Sustainable development imposed itself as a corollary of economic term "development". Sustainable development is meant to be the summation of economic, environmental and social considerations for the present and especially for the future. The concept of sustainable development plays an important role in european and global meetings since 1972, the year it has been set for the first time. Strategies necessary to achieve the objectives of sustainable development have been developed, indicators meant to indicate the result of the implementation of policies have been created, national plans were oriented towards achieving the proposed targets. I wanted to highlight the multidimensional character of the concept of sustainable development. Thus, using specialized national and international literature, I have revealed different approaches of one pillar to the detriment of another pillar depending on the specific field. In the different concepts of sustainable development, the consensus is undoubtedly agreed on its components: economic, social, environmental. Based on this fact, the concept of sustainability has different connotations depending on the specific content of each discipline: biology, economics, sociology, environmental ethics. The multidimensional valence of sustainable development consists of three pillars ability to act together for the benefit of present and future generations. Being a multidimensional concept, importance attached to a pillar over another is directed according to the particularities of each field: in economy profit prevails, in ecology care of natural resources is the most important, the social aims improving human living conditions. The challenge of sustainable development is to combine all the economic, environmental and social benefits and the present generation to come. Ecological approach is reflected in acceptance of limited natural resources by preserving natural capital. In terms of the importance of

    Theories of social surrogacy and embodied cognition assume that cognitive associations with nonhuman stimuli can be affectively charged. In the current research, we examined whether the "comfort" of comfort foods comes from affective associations with relationships. Two experiments support the hypotheses that comfort foods are associated with relationships and alleviate loneliness. Experiment 1 found that the consumption of comfort foods automatically activates relationship-related concepts. Experiment 2 found that comfort foods buffer against belongingness threats in people who already have positive associations with relationships (i.e., are secure in attachment style). Implications for social surrogacy, need to belong, embodied cognition, and eating behavior are discussed.

    Natural materials, such as bone, integrate living cells composed of organic molecules together with inorganic components. This enables combinations of functionalities, such as mechanical strength and the ability to regenerate and remodel, which are not present in existing synthetic materials. Taking a cue from nature, we propose that engineered 'living functional materials' and 'living materials synthesis platforms' that incorporate both living systems and inorganic components could transform the performance and the manufacturing of materials. As a proof-of-concept, we recently demonstrated that synthetic gene circuits in Escherichia coli enabled biofilms to be both a functional material in its own right and a materials-synthesis platform. To demonstrate the former, we engineered E. coli biofilms into a chemical-inducer-responsive electrical switch. To demonstrate the latter, we engineered E. coli biofilms to dynamically organize biotic-abiotic materials across multiple length scales, template gold nanorods, gold nanowires, and metal/semiconductor heterostructures, and synthesize semiconductor nanoparticles (Chen, A. Y. et al. (2014) Synthesis and patterning of tunable multiscale materials with engineered cells. Nat. Mater. 13, 515-523.). Thus, tools from synthetic biology, such as those for artificial gene regulation, can be used to engineer the spatiotemporal characteristics of living systems and to interface living systems with inorganic materials. Such hybrids can possess novel properties enabled by living cells while retaining desirable functionalities of inorganic systems. These systems, as living functional materials and as living materials foundries, would provide a radically different paradigm of materials performance and synthesis-materials possessing multifunctional, self-healing, adaptable, and evolvable properties that are created and organized in a distributed, bottom-up, autonomously assembled, and environmentally sustainable manner.

    When designing climate installations, the PMV (Predicted Mean Vote) and PPD (Predicted Percentage Dissatisfied index) values are used as guidelines. Installations are designed in such a way that the 'average' user in a 'steady-state' condition experiences thermal comfort. Studies show that individual physiological processes might be suitable for integration in the design models. [Dutch] Bij het ontwerp van klimaatinstallaties worden de PMV/PPD-waarden van Fanger (PMV staat voor de Predicted Mean Vote index en PPD is de Predicted Percentage Dissatisfied index) als richtlijn gebruikt. Installaties worden zodanig ontworpen dat een 'gemiddelde' persoon in een 'steady-state' conditie deze als thermisch comfortabel ervaart. Studies wijzen uit dat individuele fysiologische processen mogelijk ook in ontwerpmodellen inpasbaar zijn.

    Racing bicycles have evolved significantly over the past decades as technology and cyclists' comfort have become a critical design issue. Although ample research has been conducted on comfort for other means of transportation, cyclists' perception of dynamic comfort has received scant attention in the scientific literature. The present study investigates how enthusiast cyclists conceptualize comfort using an online survey with 244 respondents. The purpose is to determine which factors contribute to comfort when riding a bicycle, to identify situations in which comfort is relevant and to determine the extent to which vibrations play a role in comfort evaluations. We found that comfort is influenced by factors related to bicycle components (specifically the frame, saddle and handlebar), as well as environmental factors (type or road, weather conditions) and factors related to the cyclist (position, adjustments, body parts). Respondents indicated that comfort is a concern when riding a bicycle in most situations and they believed that comfort is compatible with performance. The PCA analysis shows that for the perception "human factor-body parts" are put in evidence, and the "cyclist's comfort" evaluation is mainly based on certain qualities related to the bicycle components, then the road and external conditions (e.g. weather, temperature).

    Full Text Available The cooperative housing sector is directed at low and medium income residents who cannot afford to buy their homes in the regular private market. Due to social housing legislation, it is possible to build cooperative housing below regular market costs and use tax benefits, therefore providing affordable dwellings to their owners. Traditional cooperative housing used to provide less comfort and higher running costs in indoor and domestic hot water heating than in standard construction. However, cooperative housing has started to change its method of traditional construction towards sustainable construction, in order to benefit from the savings on energy consumption and domestic water as well as to provide an improvement as far as the comfort of its residents is concerned. Therefore, in this article, the savings in electricity and natural gas in different building settlements, calculated for Madalena building—sustainable construction—and for Azenha de Cima building—traditional construction—will be presented, according to two different criteria of calculation: efficiency of dwellings at a pre-determined standard level of indoor comfort opposed to real consumptions made by residents. For each building under analysis, an energy audit and further monitoring were brought in, in order to issue an energy evaluation according to the Portuguese energy agency rules. Results showed an expected decrease of the operational costs of natural gas and electricity, obtained by the use of efficient building systems and equipment, as well as a decrease of the payback period for each situation.

    Few studies have analyzed the shapes of pillows. The purpose of this study was to investigate the relationship between the pillow shape design and subjective comfort level for asymptomatic subjects. Four basic pillow designs factors were selected on the basis of literature review and recombined into 8 configurations for testing the rank of degrees of comfort. The data were analyzed by the analytic hierarchy process method to determine the most comfortable pillow. Pillow number 4 was the most comfortable pillow in terms of head, neck, shoulder, height, and overall comfort. The design factors of pillow number 4 were using a combination of standard, cervical, and shoulder pillows. A prototype of this pillow was developed on the basis of the study results for designing future pillow shapes. This study investigated the comfort level of particular users and redesign features of a pillow. A deconstruction analysis would simplify the process of determining the most comfortable pillow design and aid designers in designing pillows for groups.

    Full Text Available The analysis and regulation of workplace, working instruments, the comfort of office chair, business environment (sound, lighting, climate, vibration, temperature, and humidity, work and break times, analysis and editing of the organization, are some of the topics of interest of ergonomics. Environmental impact and conditions have important role on the employee’s working comfortably and efficiently. Therefore these conditions need to be aligned to the human body nature. Unsuitable working conditions (noise, etc. cause additional load, which the human body endures, and this additional load reveals the signs of tiredness in the body. Even an office environment, unsuitable physical environment impairs health of workers and reduces the performance. Therefore, office climate, environmental factors such as lighting and noise must be harmonized with the employee’s body nature in all working environments. Seating comfort is one of the important factors affecting the performance of employees in the office environment. There are so many studies about chair dimensions and the disorders on human body which were caused by the inappropriate chair dimensions and sitting positions. However, there are a spot of studies about the surface of the chair and the discomfort caused by the chair cover and its negative performance effects. In this study, some results of seat cover analysis for the design of an ergonomic chair. Recently, ease of cleaning, low cost advantages caused the increasing of the use of artificial leather especially on the surface of the seat used in offices. The physical properties of natural leather and artificial leather were compared as the candidate covers to be used on the design of an ergonomic office chair.

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available This paper discusses possible contributions of psychologists to sustainable transportation. It is argued that in order to reach sustainable transportation, among others, behaviour changes of individual car users are needed. As transport policies will be more effective if they target important antecedents of travel behaviour, first, factors influencing such behaviour are discussed. It is argued that car use is very attractive and sometimes even necessary for many different reasons. This implies that a combination of policies is called for, each targeting different factors that support car use and hinder the use of more sustainable modes of transport. Next, the paper elaborates on policy strategies that may be employed to achieve sustainable transportation by changing car use. Increasing the attractiveness of sustainable transport modes by means of pull measures seems not sufficient to reduce the level of car use. Besides, car use should be made less attractive by means of push measures to force drivers to reconsider their travel behaviour. The acceptability of such policies may be increased by clearly communicating the aim of these policies, and the expected positive consequences (e.g., less congestion, improved environmental quality. Moreover, possible negative effects for individual freedom may be compensated by implementing additional policies aimed at facilitating the use of sustainable transport modes.

  11. Human Behavior & Low Energy Architecture: Linking Environmental Adaptation, Personal Comfort, & Energy Use in the Built Environment

    Science.gov (United States)

    Langevin, Jared

    Truly sustainable buildings serve to enrich the daily sensory experience of their human inhabitants while consuming the least amount of energy possible; yet, building occupants and their environmentally adaptive behaviors remain a poorly characterized variable in even the most "green" building design and operation approaches. This deficiency has been linked to gaps between predicted and actual energy use, as well as to eventual problems with occupant discomfort, productivity losses, and health issues. Going forward, better tools are needed for considering the human-building interaction as a key part of energy efficiency strategies that promote good Indoor Environmental Quality (IEQ) in buildings. This dissertation presents the development and implementation of a Human and Building Interaction Toolkit (HABIT), a framework for the integrated simulation of office occupants' thermally adaptive behaviors, IEQ, and building energy use as part of sustainable building design and operation. Development of HABIT begins with an effort to devise more reliable methods for predicting individual occupants' thermal comfort, considered the driving force behind the behaviors of focus for this project. A long-term field study of thermal comfort and behavior is then presented, and the data it generates are used to develop and validate an agent-based behavior simulation model. Key aspects of the agent-based behavior model are described, and its predictive abilities are shown to compare favorably to those of multiple other behavior modeling options. Finally, the agent-based behavior model is linked with whole building energy simulation in EnergyPlus, forming the full HABIT program. The program is used to evaluate the energy and IEQ impacts of several occupant behavior scenarios in the simulation of a case study office building for the Philadelphia climate. Results indicate that more efficient local heating/cooling options may be paired with wider set point ranges to yield up to 24

Through joint angles to describe operating posture of upper limb, the joint angles are taken as independent variables to establish the comfort model of operating posture. Factor analysis is adopted to decrease the variable dimension; the model’s input variables are reduced from 16 joint angles to 4 comfort impact factors, and the output variable is operating comfort score. The Chinese virtual human body model is built by CATIA software, which will be used to simulate and evaluate the operators’ operating comfort. With 22 groups of evaluation data as training sample and validation sample, GEP algorithm is used to obtain the best fitting function between the joint angles and the operating comfort; then, operating comfort can be predicted quantitatively. The operating comfort prediction result of human-machine interface layout of driller control room shows that operating comfort prediction model based on GEP is fast and efficient, it has good prediction effect, and it can improve the design efficiency.

    Mills, Kathryn; Blanch, Peter; Vicenzino, Bill

    2011-08-01

    Comfort is a vital component of orthosis therapy. The purpose of this study was to examine what features of orthoses (design or hardness) influence the perception of comfort by using previously established footwear comfort measures: 100-mm visual analog scale (VAS) and ranking scale. Twenty subjects were consecutively allocated to two experiments consisting of five sessions of repeated measures. Comfort measures were taken from four prefabricated orthosis in each session using the VAS (experiment 1) and ranking scale (experiment 2). Subjects in experiment 1 were also asked to rate each orthosis relative to their shoe using a criterion scale. Measures were taken in both walking and jogging. A soft-flat orthosis was found to be significantly more comfortable than all contoured orthoses, including one of the same hardness using both the VAS and ranking scale. Using the VAS, differences between the soft-flat and contoured orthoses were also found to be clinically meaningful for dimensions of overall comfort and arch cushioning (>10.2 mm). Perceived comfort of orthoses significantly differed between walking and jogging on the VAS but was not clinically meaningful. Comparisons between the VAS and criterion scale detected a VAS difference of 11.34 mm between orthoses judged as comfortable as my shoe and slightly more comfortable than my shoe. There was a VAS difference of 17.49 mm between orthoses judged as comfortable as my shoe and slightly less comfortable than my shoe. Healthy subjects prioritize contouring over hardness when judging the comfort of orthoses. Clinically meaningful changes were required to change or enhance the comfort of orthoses standardized in material type and fabrication.

    Full Text Available Seat comfort is one of the main factors that consumers consider when purchasing a car. In this study, we develop a dummy with a shear-force sensor to evaluate seat comfort. The sensor has dimensions of 25 mm × 25 mm × 26 mm and is made of S45C. Electroless nickel plating is employed to coat its surface in order to prevent corrosion and oxidation. The proposed sensor is validated using a qualified load cell and shows high accuracy and precision (measurement range: -30-30 N; sensitivity: 0.1 N; linear relationship: R = 0.999; transverse sensitivity: <1%. The dummy is manufactured in compliance with the SAE standards (SAE J826 and incorporates shear sensors into its design. We measure the shear force under four driving conditions and at five different speeds using a sedan; results showed that the shear force increases with speed under all driving conditions. In the case of acceleration and deceleration, shear force significantly changes in the lower body of the dummy. During right and left turns, it significantly changes in the upper body of the dummy.

    Full Text Available Turkey is a big country of a varied topography and so it has many climatic zones. Tourism is one of the most important sector either at national or international level. On the other hand with its natural and cultural values, rich environmental sources and unique location linking the two continents, Turkey is an important country having the ability of supplying media for various types of tourism activity and alternative tourism approaches. In this frame, with their various climatic properties, Province of Artvin located in Blacksea Region is one of the main sources of recreation and tourism areas. Besides the touristic potential of the province, its natural specialties of landscape and climate are being a good source for scientific researches have had to be determined. In this study it was aimed that the most suitable areas for climatic comfort in Artvin Province were determined. Twelve different were chosen to define climatic variations. Average temperature, moister and wind speed values of these different climate stations were transferred into GIS environment by using Arc View 3.3 software. From the data transferred into GIS environment, climate maps created and most suitable areas for climatic comfort were determined.

    The ISO 2631-1 ( 1997 ) provides methodologies for assessment of the seated human body comfort in response to vibrations. The standard covers various conditions such as frequency content, direction and location of the transmission of the vibration to the human body. However, the effects of seat structural dynamics mode shapes and corresponding resonances have not been discussed. This study provides important knowledge about the effects of vehicle seat structural vibration modes on discomfort assessment. The occupied seat resonant frequencies and corresponding vibration modes were measured and comfort test was carried out based on the paired comparison test method. The results show that the ISO 2631-1 ( 1997 ) method significantly underestimates the vibration discomfort level around the occupied seat twisting resonant frequencies. This underestimation is mainly due to the ISO suggested location of the accelerometer pad on the seatback. The centre of the seatback is a nodal point at the seat twisting mode. Therefore, it underestimates the total vibration transferred to the occupant body from the seatback. The effects of the vehicle seat structural dynamics have not been discussed in the human body vibration ISO . The results of this research show that the current measurement method suggested by ISO 2631-1 (1997) can significantly underestimate the vibration discomfort level at around the seat structural vibration mode.

    In the United Kingdom several educational buildings were built in the last decades with a strong environmental ethos, real icons of a new generation of low-energy sustainable buildings. For some of the buildings the performance was assessed. Also in the Netherlands several new concepts were developed for sustainable schools during the last years. This is an interesting topic as many of those schools had problems concerning energy efficiency, indoor air quality and thermal comfort. In the case of sustainable schools much effort was put into the design process of the schools to try to find better solutions to face the problems of the traditional designs. This resulted in different solution concepts, which raises the question which are better school concepts. From the literature three evaluations from the UK and one overview of five sustainable educational buildings from the Netherlands are given, which show that sustainable educational buildings are not always without flaws. In the paper two of the first Dutch sustainable elementary schools are compared with nine more traditional schools of the Netherlands to conclude whether the sustainable schools perform better than traditional schools.

    2014-08-01

    Full Text Available This study develops a sustainable housing model for the Mosquitia region of Honduras, aimed at improving the living conditions of indigenous communities and reducing their vulnerability to the effects of climate change. The improved housing efficiency and resilience will contribute to strengthen sanitation and hygiene, improve the living comfort and reduce environmental impact, particularly focusing on preserving the forest biodiversity. The project was developed following the criteria of environmental, technical, social and economic sustainability to propose a shared model, reproducible by the beneficiaries living in different kinds of Mosquitian ecosystems. Increased building efficiency is obtained through optimization of construction techniques and improvement of materials’ performances. The main material of the proposed dwelling is wood, coherently with the “Miskita” tradition; the increase of its durability, which is obtained by proper seasoning and protection from atmospheric agents and parasites, contributes to the optimization of the use of this natural resource and to reducing the impact on deforestation, which threatens forest biodiversity. The data collection campaign, conducted before developing the housing model design and which has aimed at obtaining information on technical and social aspects related to residences’ welfare and health conditions, has highlighted the great importance of improving the construction model. Despite the advance in sanitary conditions and the economic level, the data collection campaign revealed that even the most developed communities amongst those visited have been perpetrating substantial construction errors, which reduce the resilience of structures to extreme natural phenomena, such as tropical storms and hurricanes, which frequently affect the Mosquitia region. This unexpected discovery increased the importance of housing model design in order to correct these improper construction

    2014-01-01

    The willingness of public authority to delegate social and environmental regulation to the private sector has varied from sector to sector, but has often led to the establishment of ‘voluntary’ standards and certifications on sustainability. Many of these have taken the form of ‘stewardship...... councils’ and ‘sustainability roundtables’ and have been designed around a set of institutional features seeking to establish legitimacy, fend off possible criticism, and ‘sell’ certifications to potential users. The concept of ‘roundtabling’ emphasizes the fitting a variety of commodity......-specific sustainability situations into a form that not only ‘hears more voices’ (as in ‘multi-stakeholder’), but also portrays to give them equal standing at the table of negotiations (roundtable), thus raising higher expectations on accountability, transparency and inclusiveness.

    The long-term substitution of fossil resources can only be achieved through a bio-based economy, with biorefineries and bio-based products playing a major role. However, it is important to assess the implications of the transition to a bio-based economy. Life cycle-based sustainability assessment is probably the most suitable approach to quantify impacts and to identify trade-offs at multiple levels. The extended utilisation of biomass can cause land use change and affect food security of the most vulnerable people throughout the world. Although this is mainly a political issue and governments should be responsible, the responsibility is shifted to companies producing biofuels and other bio-based products. Organic wastes and lignocellulosic biomass are considered to be the preferred feedstock for the production of bio-based products. However, it is unlikely that a bio-based economy can rely only on organic wastes and lignocellulosic biomass.It is crucial to identify potential problems related to socio-economic and environmental issues. Currently there are many approaches to the sustainability of bio-based products, both quantitative and qualitative. However, results of different calculation methods are not necessarily comparable and can cause confusion among decision-makers, stakeholders and the public.Hence, a harmonised, globally agreed approach would be the best solution to secure sustainable biomass/biofuels/bio-based chemicals production and trade, and to avoid indirect effects (e.g. indirect land use change). However, there is still a long way to go.Generally, the selection of suitable indicators that serve the purpose of sustainability assessment is very context-specific. Therefore, it is recommended to use a flexible and modular approach that can be adapted to various purposes. A conceptual model for the selection of sustainability indicators is provided that facilitates identifying suitable sustainability indicators based on relevance and significance in a

    Fanger's PMV equation is the result of the combined quantitative effects of the air temperature, mean radiant temperature, relative air velocity, humidity, activity level and clothing insulation. This paper contains a comparison of suit dresses and summer clothes in terms of thermal comfort, Fanger's PMV equation. Studies were processed in the winter for an office, which locates in Ankara, Turkey. The office was partitioned to fifty square cells. Humidity, relative air velocity, air temperature and mean radiant temperature were measured on the centre points of these cells. Thermal comfort analyses were processed for suit dressing (Icl = 1 clo) and summer clothing (Icl = 0.5 clo). Discomfort/comfort in an environment for different clothing types can be seen in this study. The relationship between indoor thermal comfort distribution and clothing type was discussed. Graphics about thermal comfort were sketched according to cells. Conclusions about the thermal comfort of occupants were given by PMV graphics.

    The perceived differences between comfortable and uncomfortable shoes and the fit preferences in the different regions of ladies' shoes were explored. Twenty Hong Kong Chinese females participated in the study. Each participant wore and rated the different aspects of their own comfortable and uncomfortable shoes. The Wilcoxon signed rank tests showed significant differences in ten perceived characteristics between the comfortable and uncomfortable shoes. Among the ten were tactile, auditory and olfactory sensations. The ten items reliably (Cronbach alpha>0.9) distinguished between comfortable and uncomfortable shoes. There were no significant differences between comfortable and uncomfortable shoes for aesthetic-related characteristics. Further analysis on the fit ratings showed a significant impact on the fit preferences in the Toe region (pcomfortable shoes and also brings out the criteria that a comfortable shoe does not necessarily have the same perceived fit in every region of a shoe.

    Background: Suicide is a significant public health concern, which impacts on health outcomes. Few suicide research studies have been interdisciplinary. We combined a psychobiographical autopsy with a visual arts autopsy, in which families donated stories, images and objects associated with the lived life of a loved one lost to suicide. From this interdisciplinary research platform, a mediated exhibition was created ( Lived Lives ) with artist, scientist and families, co-curated by communities, facilitating dialogue, response and public action around suicide prevention. Indigenous ethnic minorities (IEMs) bear a significant increased risk for suicide. Irish Travellers are an IEM with social and cultural parallels with IEMs internationally, experiencing racism, discrimination, and poor health outcomes including elevated suicide rates (SMR 6.6). Methods: An adjusted Lived Lives exhibition, Lived Lives: A Pavee Perspective manifested in Pavee Point, the national Traveller and Roma Centre. The project was evaluated by the Travelling Community as to how it related to suicide in their community, how it has shaped their understanding of suicide and its impacts, and its relevance to other socio-cultural contexts, nationally and internationally. The project also obtained feedback from all relevant stakeholders. Evaluation was carried out by an international visual arts research advisor and an independent observer from the field of suicide research. Results: Outputs included an arts-science mediated exhibition with reference to elevated Irish Traveller suicide rates. Digital online learning materials about suicide and its aftermath among Irish Travellers were also produced. The project reached its target audience, with a high level of engagement from members of the Travelling Community. Discussion: The Lived Lives methodology navigated the societal barriers of stigma and silence to foster communication and engagement, working with cultural values, consistent with an adapted

    This paper presents the first results of a PhD research on psychological comfort of clothing. In order to understand and conceptualize the psychological aspects of clothing comfort, a variation of the Delphi Method was used to seek opinions from experts. This method was chosen because of its consensus-building features. The results were obtained from a qualitative text analysis, conducted over the experts’ responses to the first round of questions. The analytic process shed some light on the formation of the psychological comfort concept as well as the potential attributes to be evaluated when assessing this comfort dimension.

  16. Using the Comfortability-in-Learning Scale to Enhance Positive Classroom Learning Environments

    2014-08-01

    Full Text Available A goal of higher education is to advance learning. This study examined the role “comfortability” plays in that process. Defined as the level of comfort students experience with their classmates, instructor, and course material, comfortability addresses how secure a student feels in the classroom. Comfortability was assessed multiple times during one semester with undergraduate students and found student comfortability significantly increased across the course of the semester and significantly predicted affective learning. These findings suggest the importance of the classroom environment in the learning process and support the need for faculty to consider “non-academic” factors in addition to course content.

    Little is known about whether comfort eating actually functions to reduce psychological stress. In addition, the effectiveness of comfort eating may be particularly relevant in the context of depression, but no study has tested whether comfort eating processes might depend on severity of depressive symptomology. This study tested 1) whether greater comfort eating statistically buffers the relationship between adverse life events and perceived psychological stress at age 18-19, and 2) whether potential stress-buffering effects may differ by level of depressive symptoms. These relationships were examined in the NHLBI Growth and Health Study, comprising 2379 young adult women. Participants self-reported experiences with adverse life events, their perceived psychological stress, and whether they tended to eat more while experiencing certain negative emotions. As hypothesized, the relationship between adverse life events and perceived stress depended on comfort eating status (p = .033). The effect of adverse events on perceived stress was attenuated among comfort eaters compared to non-comfort eaters (p = .004), but this buffering effect was not shown in participants with an elevated level of depressive symptoms. In conclusion, among young adult women without high depressive symptoms, comfort eaters may experience reduced perceived stress compared to those who do not engage in this behavior. Intervention researchers should also consider the possible benefits of comfort eating. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The long-term effects of comfort food in an anxiogenic model of stress have yet to be analyzed. Here, we evaluated behavioral, endocrine and metabolic parameters in rats submitted or not to chronic unpredictable mild stress (CUMS), with access to commercial chow alone or to commercial chow and comfort food. Stress did not alter the preference for comfort food but decreased food intake. In the elevated plus-maze (EPM) test, stressed rats were less likely to enter/remain in the open arms, as well as being more likely to enter/remain in the closed arms, than were control rats, both conditions being more pronounced in the rats given access to comfort food. In the open field test, stress decreased the time spent in the centre, independent of diet; neither stress nor diet affected the number of crossing, rearing or grooming episodes. The stress-induced increase in serum corticosterone was attenuated in rats given access to comfort food. Serum concentration of triglycerides were unaffected by stress or diet, although access to comfort food increased total cholesterol and glucose. It is concluded that CUMS has an anorexigenic effect. Chronic stress and comfort food ingestion induced an anxiogenic profile although comfort food attenuated the endocrine stress response. The present data indicate that the combination of stress and access to comfort food, common aspects of modern life, may constitute a link among stress, feeding behavior and anxiety.

    Some evidence suggests that attitude toward computer-based instruction is an important determinant of success in online learning. We sought to determine how comfort using computers and perceptions of prior online learning experiences have changed over the past decade, and how these associate with learning outcomes. Each year from 2003-2011 we conducted a prospective trial of online learning. As part of each year's study, we asked medicine residents about their comfort using computers and if their previous experiences with online learning were favorable. We assessed knowledge using a multiple-choice test. We used regression to analyze associations and changes over time. 371 internal medicine and family medicine residents participated. Neither comfort with computers nor perceptions of prior online learning experiences showed a significant change across years (p > 0.61), with mean comfort rating 3.96 (maximum 5 = very comfortable) and mean experience rating 4.42 (maximum 6 = strongly agree [favorable]). Comfort showed no significant association with knowledge scores (p = 0.39) but perceptions of prior experiences did, with a 1.56% rise in knowledge score for a 1-point rise in experience score (p = 0.02). Correlations among comfort, perceptions of prior experiences, and number of prior experiences were all small and not statistically significant. Comfort with computers and perceptions of prior experience with online learning remained stable over nine years. Prior good experiences (but not comfort with computers) demonstrated a modest association with knowledge outcomes, suggesting that prior course satisfaction may influence subsequent learning.

    Geriatric patients represent a large and complex subgroup seen in emergency departments (EDs). Competencies in geriatric emergency medicine (EM) training have been established. Our objectives were to examine Canadian postgraduate year (PGY)-5 EM residents' comfort with the geriatric EM competency domains, assess whether Canadian EM residents become more comfortable through residency, and determine whether geriatric educational exposures are correlated with resident comfort with geriatric EM. A national, cross-sectional study of PGY-1 and PGY-5 Royal College EM residents was conducted to determine their comfort in geriatric EM clinical competency domains. Residents reported their level of comfort in satisfying each competency domain using a seven-point Likert scale. Residents were also asked about the location of their medical education as well as the type and number of different geriatric exposures that they had received to date. Of the 141 eligible residents from across Canada, 77% (109) consented to participate. None of the PGY-1 EM residents and 34% (14) of PGY-5 EM residents reported that they were comfortable with all eight geriatric EM competency domains. PGY-5 EM residents were significantly more comfortable than PGY-1 EM residents. Residents reported a highly variable range of geriatric educational exposures obtained during training. No relationship was found between resident-reported comfort and the nature or number of geriatric exposures that they had received. Current Royal College EM residency training in Canada may not be adequately preparing graduates to be comfortable with defined competencies for the care of older ED patients.

    It was reported that next to style, comfort is the second key aspect in purchasing footwear. One of the most important components of footwear is the shoe sole, whose design is based on many factors such as foot shape/size, perceived comfort and materials. The present paper focuses on the parametric analysis of a shoe sole to improve the perceived comfort. The sensitivity of geometric and material design factors on comfort degree was investigated by combining real experimental tests and CAD-FEM simulations. The correlation between perceived comfort and physical responses, such as plantar pressures, was estimated by conducting real tests. Four different conditions were analyzed: subjects wearing three commercially available shoes and in a barefoot condition. For each condition, subjects expressed their perceived comfort score. By adopting plantar sensors, the plantar pressures were also monitored. Once given such a correlation, a parametric FEM model of the footwear was developed. In order to better simulate contact at the plantar surface, a detailed FEM model of the foot was also generated from CT scan images. Lastly, a fractional factorial design array was applied to study the sensitivity of different sets of design factors on comfort degree. The findings of this research showed that the sole thickness and its material highly influence perceived comfort. In particular, softer materials and thicker soles contribute to increasing the degree of comfort. Copyright © 2012 IPEM. Published by Elsevier Ltd. All rights reserved.

    2006-05-01

    Exergy is the elixir of life. Exergy is that portion of energy available to do work. Elixir is defined as a substance held capable of prolonging life indefinitely, which implies sustainability of life. In terms of mathematics and engineering, exergy sustainability is defined as the continuous compensation of irreversible entropy production in an open system with an impedance and capacity-matched persistent exergy source. Irreversible and nonequilibrium thermodynamic concepts are combined with self-organizing systems theories as well as nonlinear control and stability analyses to explain this definition. In particular, this paper provides a missing link in the analysis of self-organizing systems: a tie between irreversible thermodynamics and Hamiltonian systems. As a result of this work, the concept of ''on the edge of chaos'' is formulated as a set of necessary and sufficient conditions for stability and performance of sustainable systems. This interplay between exergy rate and irreversible entropy production rate can be described as Yin and Yang control: the dialectic synthesis of opposing power flows. In addition, exergy is shown to be a fundamental driver and necessary input for sustainable systems, since exergy input in the form of power is a single point of failure for self-organizing, adaptable systems.

    Full Text Available High capacities of currently available devices for sound registering and processing have generated a need for sound insulated spaces dedicated to exchange of confidential information. In such spaces, preventing propagation of vibroacoustic signals both by the way of air and construction elements entails complete insulation of the room. In order to meet this requirement, proper chemical composition of air and stabilized temperature conditions have to be guaranteed. The paper discusses questions related to the process of solving the task of providing thermal comfort and satisfying air quality in a room for confidential discussions. It presents prototype solutions of installations dedicated to stabilize human-friendly conditions inside a modular chamber provided with acoustic insulation.

    In this work, the special design of a pair of ski gloves has been assessed in terms of thermal comfort. The glove 2in1 Gore-Tex has a dual-chamber construction, with two possible wearing configurations: one called “grip” to maximize finger flexibility and one called “warm” to maximize thermal insulation in extremely cold conditions. The dual-chamber gloves has been compared with two regular ski gloves produced by the same company. An intermittent test on a treadmill was carried out in a climatic chamber: it was made of four intense activity phases, during which the volunteer ran at 9 km/h on a 5% slope for 4 minutes, spaced out by 5-min resting phases. Finger temperature measurements were compared with the thermal sensations expressed by two volunteers during the test.

    The "wearability" of wearable technology addresses the factors that affect the degree of comfort the wearer experiences while wearing a device, including physical, psychological, and social aspects. While the physical and psychological aspects of wearing technology have been investigated since early in the development of the field of wearable computing, the social aspects of wearability have been less fully-explored. As wearable technology becomes increasingly common on the commercial market, social wearability is becoming an ever-more-important variable contributing to the success or failure of new products. Here we present an analysis of social aspects of wearability within the context of the greater understanding of wearability in wearable technology, and focus on selected theoretical frameworks for understanding how wearable products are perceived and evaluated in a social context. Qualitative results from a study of social acceptability of on-body interactions are presented as a case study of social wearability.

    intelligibility for students. Two room acoustic parameters are shown relevant for a speaker: the voice support, linked to vocal effort, and the decay time derived from an oral-binaural impulse response, linked to vocal comfort. Theoretical prediction models for room-averaged values of these parameters......Current European regulatory requirements or guidelines for reverberation time in classrooms have the goal of enhancing speech intelligibility for students and reducing noise levels in classrooms. At the same time, school teachers suffer frequently from voice problems due to high vocal load...... are combined with a model of speech intelligibility based on the useful-to-detrimental ratio and empirical models of signal-to-noise ratio in classrooms in order to derive classroom acoustic guidelines, taking into account physical volume restrictions linked to the number of students present in a classroom...

  17. American style or Turkish chair: the triumph of bodily comfort.

    This article investigates the reciprocal influence of Ottoman Turkish and American interiors in the development of seating furniture. Seating furniture is unique because it involves a direct and physical interaction between the piece of furniture and the body, while at the same time it is part of a public space where social interactions occur. I will argue that the interactions between the Ottoman Turks and Americans are reflected in the way these traditions modified their seating furniture as they sought to mediate cultural, political and social differences between them. The concept of bodily comfort will serve as a common thread in understanding the origin of the expression "American style" (Amerikan stili or Amerikan tarzı) in modern Turkish language, the "Turkish chairs" in Victorian America in the late nineteenth century and the English language use of words such as sofa, ottoman and divan.

    to preserve the teachers’ voices and maximize their comfort, it is necessary to understand the underlaying relationship between classroom acoustics and teachers’ voice production. This paper presents a brief summary of investigations looking into this relationship. A pilot study, carried out in different...... to introduce the use of vocal doses for the investigation of voice production under different classroom acoustics and noise conditions, finding that the relative effect of noise on voice production is more important than the effect of room acoustics.......Teachers suffer from voice problems more often than the rest of the population, as a consequence of the intensive use of their voices during teaching. Noise and classroom acoustics have been defined as hazards eventually leading to voice problems. In order to make a good classroom acoustic design...

    Chemical reactions between ozone and pollutants commonly found indoors have been suggested to cause adverse health and comfort effects among building occupants. Of special interest are reactions with terpenes and other pollutants containing unsaturated carbon-carbon bonds that are fast enough...... to occur under normal conditions in various indoor settings. These reactions are known to occur both in the gas phase (homogeneous reactions) and on the surfaces of building materials (heterogeneous reactions), producing a number of compounds that can be orders of magnitude more odorous and irritating than...... their precursors. The present thesis investigates the effects of ozone-initiated reactions with limonene and with various interior surfaces, including those associated with people, on short-term sensory responses. The evaluations were conducted using a perceived air quality (PAQ) method introduced by Fanger (1988...
