    Trust (confianza) is an important component of patient-centered care and culturally competent care and a major element in the Hispanic culture. The aim of this study was to conceptualize the process of the development of interpersonal trust by hospitalized patients in their nurses. Using the grounded theory method, English-speaking Mexican American patients (N = 22) were interviewed. The core category was Making Me Feel Comfortable. The cyclical process included a beginning stage (Having Needs, Relying on the Nurse), middle stage (Coming Across to Me, Taking Care of Me, Connecting), and end point (Feeling Confianza) with two outcomes (Confiding in the Nurse, Taking Away the Negative). Anytime there was a negative element during the middle stage, this element halted any further development of trust with the nurse. Unique findings were related to Hispanic cultural values of familism and personalismo. The findings have implications which impact patient safety and quality care. © The Author(s) 2014.

    The subjective concept of acoustic comfort in eating establishments has been investigated in this study. The goal was to develop a predictive model for the acoustic comfort, by means of simple objective parameters, while also examining which other subjective acoustic parameters could help explain...... the feeling of acoustic comfort. Through several layers of anal ysis, acoustic comfort was found to be rather complex, and could not be explained entirely by common subjective parameters such as annoyance, intelligibility or privacy.

    Memory for feelings is subject to fading and bias over time. In 2 studies, the authors examined whether the magnitude and direction of bias depend on the type of feeling being recalled: emotion or mood. A few days after the U.S. Presidential elections in 2008 and 2012, participants reported how they felt about the election outcome (emotion) and how they felt in general (mood). A month after the elections, participants recalled their feelings. The intensity of past emotion was recalled more accurately than the intensity of past mood. Participants underestimated the intensity of emotion but overestimated the intensity of mood. Participants' appraisals of the importance of the election, which diminished over time, contributed to underestimating the intensity of emotion. In contrast, participants' strong emotional response to the election contributed to overestimating the intensity of mood. These opposing biases have important implications for decision making and clinical assessment. (c) 2016 APA, all rights reserved).

    Full Text Available Objective: To determine resident comfort and skill in performing ambulatory care skills. Methods: Descriptive survey of common ambulatory care skills administered to internal medicine faculty and residents at one academic medical center. Respondents were asked to rate their ability to perform 12 physical exam skills and 6 procedures, and their comfort in performing 7 types of counseling, and obtaining 6 types of patient history (4 point Likert scale for each. Self-rated ability or comfort was compared by gender, status (year of residency, faculty, and future predicted frequency of use of the skill. Results: Residents reported high ability levels for physical exam skills common to both the ambulatory and hospital setting. Fewer felt able to perform musculoskeletal, neurologic or eye exams easily alone. Procedures generally received low ability ratings. Similarly, residents’ comfort in performing common outpatient counseling was also low. More residents reported feeling very comfortable in obtaining history from patients. We found little variation by gender, year of training, or predicted frequency of use. Conclusion: Self-reported ability and comfort for many common ambulatory care skills is low. Further evaluation of this finding in other training programs is warranted.

    Enrichment of durum wheat pasta with legume flour enhances their protein and essential amino acid content, especially lysine content. However, despite its nutritional potential, the addition of a legume alters the rheological properties of pasta. High temperature drying of pasta reduces this negative effect by strengthening its protein network. The aim of our study was to determine if these changes in the pasta structure alter its in vitro carbohydrate digestibility, in vivo glycemic, insulin and satiety responses. We also investigated if high temperature drying of pasta can reduce the well-known digestive discomfort associated with the consumption of legume grains. Fifteen healthy volunteers consumed three test meals: durum wheat pasta dried at a low temperature (control), and pasta enriched with 35% faba bean dried at a low and at a very high temperature. When enriched with 35% legume flour, pasta maintained its nutritionally valuable low glycemic and insulin index, despite its weaker protein network. Drying 35% faba bean pasta at a high temperature strengthened its protein network, and decreased its in vitro carbohydrate digestion with no further decrease in its in vivo glycemic or insulin index. Drying pasta at a very high temperature reduced digestive discomfort and enhanced self-reported satiety, and was not associated with a modification of energy intake in the following meal.

    This article describes the process and results of a three-month music therapy clinical effectiveness study conducted with terminally ill patients. The purpose of this study was to quantify and evaluate the effectiveness of single-session music therapy interventions with hospice patients in three patient problem areas: pain control; physical comfort; and relaxation. Data from a total of 90 sessions conducted with a total of 80 subjects served by Hospice of Palm Beach County, Florida, were included in the study. Music therapy services were provided by five board-certified music therapists and one music therapist eligible for board certification. The subjects in this study were receiving regularly scheduled music therapy services from the hospice organization. The study used both behavioral observation and subject's self-reporting as methods of data reporting and recording. Subjects were observed for, or self-reported, their levels of pain control, physical comfort, and relaxation, both before and after each music therapy session. The subjects were served in the environments where music therapy services would normally be delivered (i.e., home, hospital, nursing home, or inpatient acute-care unit of the hospice organization). Music therapy services included live active and passive music-based experiences. These were designed to build and to establish rapport with patient or family, to facilitate family interaction and patient control, to provide support and comfort, to facilitate relaxation, to enable reminiscence and life review, to provide a frame-work for spiritual exploration and validation, and to encourage the identification and expression of feelings of anticipatory mourning and grief. A total of six hypotheses stated that there would be significant pre- to postsession differences in each of the three variables: pain control, physical comfort, and relaxation, as measured during two different session and data collection scenarios. These scenarios included the

    Thermal comfort is one of the most important aspects of the indoor environmental quality due to its effects on well-being, people's performance and building energy requirements. Its attainment is not an easy task requiring advanced design and operation of building and HVAC systems, taking...... into account all parameters involved. Even though thermal comfort fundamentals are consolidated topics for more than forty years, often designers seem to ignore or apply them in a wrong way. Design input values from standards are often considered as universal values rather than recommended values to be used...... under specific conditions. At operation level, only few variables are taken into account with unpredictable effects on the assessment of comfort indices. In this paper, the main criteria for the design and assessment of thermal comfort are discussed in order to help building and HVAC systems designers...

    2005-01-01

    Purpose: A comfortable treatment position in radiotherapy may promote patient stability and contribute to the best possible patient experience. Patients receiving radical radiotherapy for prostate cancer lie supine or prone, but little evaluation has been made of the comfort of these positions. The purpose of this research was to evaluate the comfort of the prone and supine positions and to assess any influence of feelings of anxiety. Methods: Self-reported comfort and anxiety levels were measured using visual analogue scales in the first and last weeks of treatment for patients receiving radical prostatic radiotherapy. The subjects were from two hospitals, 23 routinely treated lying prone and 21 routinely treated lying supine. Six subjects from each group were interviewed in the first week of treatment. Results: Comfort levels were high and no significant difference was found between treatment positions or between the first and last weeks of treatment. Anxiety levels were low with no significant variation according to position or week of treatment. Little correlation was seen between reported anxiety and comfort levels. Interview data supported the quantitative findings. Supine subjects indicated the need for lateral elbow support to improve feelings of stability. Conclusions: For radiotherapy of male patients without pain or other complicating factors, selection between the prone and supine positions may be made without considering comfort. Supine patients should be provided with lateral elbow support. Further research is indicated into the comfort of these positions for females and the phenomenon of low reported anxiety in male cancer patients

  17. What Students Think They Feel Differs from What They Really Feel – Academic Self-Concept Moderates the Discrepancy between Students’ Trait and State Emotional Self-Reports

    2014-01-01

    This study investigated whether there is a discrepancy pertaining to trait and state academic emotions and whether self-concept of ability moderates this discrepancy. A total of 225 secondary school students from two different countries enrolled in grades 8 and 11 (German sample; n = 94) and grade 9 (Swiss sample; n = 131) participated. Students’ trait academic emotions of enjoyment, pride, anger, and anxiety in mathematics were assessed with a self-report questionnaire, whereas to assess their state academic emotions experience-sampling method was employed. The results revealed that students’ scores on the trait assessment of emotions were generally higher than their scores on the state assessment. Further, as expected, students’ academic self-concept in the domain of mathematics was shown to partly explain the discrepancy between scores on trait and state emotions. Our results indicate that there is a belief-driven discrepancy between what students think they feel (trait assessment) and what they really feel (state assessment). Implications with regard to the assessment of self-reported emotions in future studies and practical implications for the school context are discussed. PMID:24647760

  18. Heartwarming memories: Nostalgia maintains physiological comfort.

    Nostalgia, a sentimental longing or wistful affection for the past, is a predominantly positive and social emotion. Recent evidence suggests that nostalgia maintains psychological comfort. Here, we propose, and document in five methodologically diverse studies, a broader homeostatic function for nostalgia that also encompasses the maintenance of physiological comfort. We show that nostalgia--an emotion with a strong connotation of warmth--is triggered by coldness. Participants reported stronger nostalgia on colder (vs. warmer) days and in a cold (vs. neutral or warm) room. Nostalgia, in turn, modulates the interoceptive feeling of temperature. Higher levels of music-evoked nostalgia predicted increased physical warmth, and participants who recalled a nostalgic (vs. ordinary autobiographical) event perceived ambient temperature as higher. Finally, and consistent with the close central nervous system integration of temperature and pain sensations, participants who recalled a nostalgic (vs. ordinary autobiographical) event evinced greater tolerance to noxious cold.

    Aimed at climate-responsive urban design for tropical areas, the paper attempts to answer the question whether the site-related context affects in some way the perceptual assessment of the microclimate by users of outdoor spaces. Our hypothesis was that visual cues resulting from urban design are important components of the outdoor thermal perception. Monitoring was carried out alongside the administration of standard comfort questionnaires throughout summer periods in 2012-2015 in pedestrian areas of downtown Rio de Janeiro (22° 54 10 S, 43° 12 27 W), Brazil. Campaigns took place at different points, pre-defined in respect of urban geometry attributes. For the measurements, a Davis Vantage Pro2 weather station was employed to which a gray globe thermometer was attached. Two thermal indices were used for assessing the overall meteorological conditions and comfort levels in the outdoor locations: physiological equivalent temperature (PET) and universal thermal climate index (UTCI). Our results suggest that thermal sensation in Rio depends to a large extent on the thermal environment as described by air temperature, PET, or UTCI, and that urban geometry (expressed by the sky-view factor (SVF)) may modify this relationship with increased building density associated to warmer sensation votes under moderate heat stress conditions. This relationship however reverses under strong heat stress with warmer sensations in less obstructed locations, and disappears completely under still higher heat stress, where meteorological conditions, and not the site's SVF, will drive thermal sensation.

    The present study investigated sex-differences in reports of depressive symptoms on a Norwegian translation of the short version of the Mood and Feelings Questionnaire (SMFQ). The sample comprised 9702 Norwegian adolescents (born 1993–1995, 54.9% girls), mainly attending highschool. A set of statistical analyses were run to investigate the dimensionality of the SMFQ. Girls scored significantly higher than boys on the SMFQ and used the most severe response-category far more frequently. Overall, the statistical analyses supported the essential unidimensionality of SMFQ. However, the items with the highest loadings according to the bifactor analysis, reflecting problems related to tiredness, restlessness and concentration difficulties, indicated that some of the symptoms may both be independent of and part of the symptomatology of depression. Measurement invariance analysis showed that girls scored slightly higher on some items when taking the latent variable into account; girls had a lower threshold for reporting mood problems and problems related to tiredness than boys, who showed a marginally lower threshold for reporting that no-one loved them. However, the effect on the total SMFQ score was marginal, supporting the use of the Norwegian translation of SMFQ as a continuous variable in further studies of adolescents. PMID:24062708

    To gain knowledge about nurses' comfort level in assessing spiritual matters and to learn what questions nurses use in practice related to spiritual assessment. Spirituality is important in holistic nursing care; however, nurses report feeling uncomfortable and ill-prepared to address this domain with patients. Education is reported to impact nurses' ability to engage in spiritual care. This cross-sectional exploratory survey reports on a mixed-method study examining how comfortable nurses are with spiritual assessment. In 2014, a 21-item survey with 10 demographic variables and three open-ended questions were distributed to Norwegian nurses working in diverse care settings with 172 nurse responses (72 % response rate). SPSS was used to analyse quantitative data; thematic analysis examined the open-ended questions. Norwegian nurses reported a high level of comfort with most questions even though spirituality is seen as private. Nurses with some preparation or experience in spiritual care were most comfortable assessing spirituality. Statistically significant correlations were found between the nurses' comfort level with spiritual assessment and their preparedness and sense of the importance of spiritual assessment. How well-prepared nurses felt was related to years of experience, degree of spirituality and religiosity, and importance of spiritual assessment. Many nurses are poorly prepared for spiritual assessment and care among patients in diverse care settings; educational preparation increases their comfort level with facilitating such care. Nurses who feel well prepared with spirituality feel more comfortable with the spiritual domain. By fostering a culture where patients' spirituality is discussed and reflected upon in everyday practice and in continued education, nurses' sense of preparedness, and thus their level of comfort, can increase. Clinical supervision and interprofessional collaboration with hospital chaplains and/or other spiritual leaders can

    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.

    2011-04-01

    Using data from a probability based sample of adult men who have sex with men (MSM) we examined the association of negative life factors during adolescence and adult HIV status. 521 MSM reported on experiences of connectedness to community, comfort with sexuality, harassment and discrimination due to their sexual orientation at ages 12-18 years. HIV status was determined by serological testing. Overall, men reported moderate levels of being harassed, being discriminated against and high levels of feeling disconnected from gay communities while reporting high levels of being uncomfortable with their sexuality at those ages. However, in analyses of scores on these factors, higher experiences of harassment, higher levels of discrimination and more discomfort with sexuality at these ages are associated with HIV-negative status as adults. This study suggests that the relationship between negative adolescent experiences among MSM and adult HIV infection may not be straightforward, but may also dependent upon aspects of the intensity of the negative experiences, the relationship of the victim and the perpertrator(s), the sexual identity of the victim at the time and/or the number of these experiences or the length of time over which they occurred. Studies investigating specific multiple stressors in adolescent gay development and their effect on adult health outcomes are needed.

    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.

    This study explored the reasons and motives underlying the decisions of individuals with strong Machiavellian attitudes (High Machs). One hundred and fifty undergraduate students completed the Mach-IV test, and their contributions to, financial success in and narrative reports of a public goods game were analysed. High Machs contributed less to the public good and gained more benefit than Low Machs. Analysis of the narrative reports showed that High Machs used significantly fewer verbs referring to emotional involvement and first person plural verb forms, than did Low Machs. This study confirmed previous findings that High Machs have a cool and rational character and a proself orientation and showed that their lack of group orientation may account for their low cooperation in social dilemmas. The results of narrative content analysis provide a new perspective on the motives and values behind High Machs' decisions and success in different fields of social life. © 2014 International Union of Psychological Science.

    Research shows that active support provision is associated with greater well-being for spouses of individuals with chronic conditions. However, not all instances of support may be equally beneficial for spouses' well-being. The theory of communal responsiveness suggests that because spouses' well-being is interdependent, spouses benefit most from providing support when they believe their support increases their partner's happiness and is appreciated. Two studies tested this hypothesis. Study 1 was a 7-day ecological momentary assessment (EMA) study of 73 spouses of persons with dementia (74%) and other conditions. In Study 1, spouses self-reported active help, perceptions of how happy the help made the partner and how much the help improved the partner's well-being, and spouses' positive and negative affect at EMA time points. Study 2 was a 7-day daily assessment study of 43 spouses of persons with chronic pain in which spouses reported their emotional support provision, perceived partner appreciation, and their own physical symptoms. Study 1 showed that active help was associated with more positive affect for spouses when they perceived the help increased their partner's happiness and improved their partner's well-being. Study 2 showed that emotional support provision was associated with fewer spouse reported physical symptoms when perceptions of partner appreciation were high. Results suggest that interventions for spouses of individuals with chronic conditions take into account spouses' perceptions of their partners' positive emotional responses. Highlighting the positive consequences of helping may increase spouses' well-being. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    One possible explanation for the dearth of psychologists working in severe mental illness (SMI) areas is a lack of training opportunities. Recent studies have shown that while training opportunities have increased, there remain fewer resources available for SMI training compared to other disorders. Examines whether students express discomfort working with this population and whether they are satisfied with their level of training in SMI. One-hundred sixty-nine students currently enrolled in doctoral programs in clinical psychology in the United States and Canada were surveyed for their comfort treating and satisfaction with training related to a number of disorders. RESULTS indicate that students are significantly less comfortable treating and finding a referral for a patient with schizophrenia as well as dissatisfied with their current training in SMI and desirous of more training. Regression analyses showed that dissatisfaction with training predicted a desire for more training; however, discomfort in treating people with SMI did not predict a desire for more training in this sample. This pattern generally held across disorders. Our results suggest general discomfort among students surveyed in treating SMI compared to other disorders.

    Unlike thermal comfort in air, little research has been undertaken exploring thermal comfort around water sports. We investigated the impact of swimming and cooling in air after swimming on thermal comfort. After 10 min of swimming-and-resting cycles in 28°C water, volunteers wearing two types of garments or in swim briefs, faced winds in 24°C air, at rest or when stepping. Thermal comfort was significantly higher during swimming than resting. Post-immersion, following maximum discomfort, in 45 of 65 tests thermal comfort improved although mean skin temperature was still cooling (0.26 [SD 0.19] °C·min(-1) - max was 0.89°C·min(-1)). When thermal comfort was re-established mean skin temperature was lower than at maximal discomfort in 39 of 54 tests (0.81 [SD 0.58] °C - max difference was 2.68°C). The reduction in thermal discomfort in this scenario could be due to the adaptation of thermoreceptors, or to reductions in cooling rates to levels where discomfort was less stimulated. The relief from the recent discomfort may explain why, later, thermal comfort returned to initial levels in spite of poorer thermal profiles. Copyright © 2014 Elsevier Inc. All rights reserved.

  19. Affect asymmetry and comfort food consumption.

    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.

    To offer an empirical understanding of characteristics associated with the fit and feel of condoms among African-American men who have sex with men (MSM), a particularly high-risk group for HIV and other sexually transmitted infections (STI) in the United States. Survey data were collected from 178 adult African-American MSM attending a community event in Atlanta, Georgia. Although the majority of participants reported that condoms generally fit properly and felt comfortable, a substantial number of men reported a variety of problems with the fit and feel of condoms. Specifically, 21% reported that condoms felt too tight, 18% reported that condoms felt too short, 10% reported that condoms felt too loose, and 7% reported that condoms felt too long. There were significant associations between men's reports of condom breakage and slippage, and their perceptions of condom fit and feel. Perceptions of condom fit and feel were also related to men's reports of seeking condoms for their size-specific properties. The fit and feel issues that men in this sample identified may be among those that contribute to their likelihood of using, or not using, condoms consistently and correctly. A better understanding of these factors will be beneficial to both condom manufacturers and sexual health professionals who share a common goal of increasing consistent and correct condom use and reducing the incidence of HIV and other STI among this and other communities.

  1. Feeling in control during labor: concepts, correlates, and consequences.

    Many studies have revealed that a sense of control is a major contributing factor to a woman's birth experience and her subsequent well-being. Since not all studies conceptualize "control" in the same way or distinguish between "external" and "internal" control, the purpose of this study is to advance understanding of how these senses of control relate to each other. Questionnaires were sent to women 1 month before birth to assess their preferences and expectations and at 6 weeks after birth to discover their experiences and assess psychological outcomes. Data are presented from 1146 women. Three control outcomes were considered: feeling in control of what staff do to you, feeling in control of your own behavior, and feeling in control during contractions. Women were less likely to report being in control of staff (39.5%) than in control of their own behavior (61.0%). Approximately one-fifth of the sample felt in control in all three ways, and another one-fifth did not feel in control in any of them. Parity was strongly associated with feeling in control, with multiparas feeling more in control than primiparas in all cases. In logistic regression analyses, feeling in control of staff was found to relate primarily to being able to get comfortable, feeling treated with respect and as an individual, and perceiving staff as considerate. Feeling in control of one's behavior and during contractions were primarily related to aspects of pain and pain relief, but also to antenatal expectations of control. Worry about labor pain was also an important antenatal predictor for primiparas. All three control outcomes contributed independently to satisfaction, with control of staff being the most significant; relationships with emotional well-being were also demonstrated. All three types of control were important to women and contributed to psychological outcomes. Internal and external control were predicted by different groups of variables. Caregivers have the potential to make a

  5. Outdoor thermal comfort.

    2011-06-01

    A review of the various approaches in understanding outdoor thermal comfort is presented. The emphasis on field surveys from around the world, particularly across Europe, enables us to understand thermal perception and evaluate outdoor thermal comfort conditions. The consistent low correlations between objective microclimatic variables, subjective thermal sensation and comfort outdoors, internationally, suggest that thermophysiology alone does not adequate describe these relationships. Focusing on the concept of adaptation, it tries to explain how this influences outdoor comfort, enabling us to inhabit and get satisfaction from outdoor spaces throughout the year. Beyond acclimatization and behavioral adaptation, through adjustments in clothing and changes to the metabolic heat, psychological adaptation plays a critical role to ensure thermal comfort and satisfaction with the outdoor environment. Such parameters include recent experiences and expectations; personal choice and perceived control, more important than whether that control is actually exercised; and the need for positive environmental stimulation suggesting that thermal neutrality is not a pre-requisite for thermal comfort. Ultimately, enhancing environmental diversity can influence thermal perception and experience of open spaces.

    This report outlines the fiscal 1998 R and D result on human feeling measurement application technology. For development of assessment technology of the impact of work fatigue on human feeling (human feeling index), and assessment technology of the adaptability and affinity between human being and environment or product (environment and product adaptability index), data storage and evaluation by measuring experiment of human feeling, and modification of every index toward the final index based on the above data were carried out. Further case studies were carried out to reflect the above both indices to design of living products or residence and office environments, and new data were also collected. The database model for using previously collected human feeling data effectively, and the sweating manikin for estimating human thermal feeling reasonably were developed. In addition, the human feeling measurement manual was prepared to diffuse these technologies. The R and D system is also described. (NEDO)

  7. Are you sitting comfortably? Perspectives of the researchers and the researched on "being comfortable".

    Science.gov (United States)

    Morris, Norma; Balmer, Brian

    2006-01-01

    In a study of volunteers in medical research, we found contrasting readings of "being comfortable" by the volunteer research subjects and the researchers. Although the experimental process (testing a new kind of diagnostic technology) involved some physical discomfort--and the researchers focused on this--the volunteers' concerns centred on feeling socially comfortable and managing feelings of embarrassment or isolation, and they generally made light of the physical aspects. The bias of volunteer concerns, which is understandable in terms of the different situations of researchers and volunteers and the different tensions they create, has potential implications for the engagement of researchers with their research subjects and prevailing standards for the ethical and accountable conduct of research.

    2014-01-01

    Children with cancer often undergo a long course of treatment, described as painful, and associated with feelings of discomfort and need of comfort. The aim of this descriptive interview study was to investigate how children, aged 3 to 9 years, undergoing cancer treatment describe their experience of comfort. The children were interviewed and asked to make drawings. Data were content analyzed and four themes were constructed--enduring discomfort, expressing discomfort, finding comfort, and comforting others. The findings show that the children endured discomfort during treatment, and were sometimes able to express it. They found comfort especially from their family and from hospital staff. The children also described that they comforted family members. The findings are in accordance with previous research about children's and adults' accounts of comfort. An incidental finding is that parents were surprised when they listened to the children's accounts of their experience of discomfort and comfort and achieved a better understanding of their children.

  11. Comfort measures: a concept analysis.

    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.

  5. Dynamic thermal environment and thermal comfort.

    Science.gov (United States)

    Zhu, Y; Ouyang, Q; Cao, B; Zhou, X; Yu, J

    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.

    It is widely accepted that listening to music improves subjective feelings and reduces fatigue sensations, and different kinds of music lead to different activations of these feelings. Recently, cardiac autonomic nervous modulation has been proposed as a useful objective indicator of fatigue. However, scientific considerations of the relation between feelings of fatigue and cardiac autonomic nervous modulation while listening to music are still lacking. In this study, we examined which subjective feelings of fatigue are related to participants' cardiac autonomic nervous function while they listen to music. We used an album of comfortable and relaxing environmental music, with blended sounds from a piano and violin as well as natural sound sources. We performed a crossover trial of environmental music and silent sessions for 20 healthy subjects, 12 females, and 8 males, after their daily work shift. We measured changes in eight types of subjective feelings, including healing, fatigue, sleepiness, relaxation, and refreshment, using the KOKORO scale, a subjective mood measurement system for self-reported feelings. Further, we obtained measures of cardiac autonomic nervous function on the basis of heart rate variability before and after the sessions. During the music session, subjective feelings significantly shifted toward healing and a secure/relaxed feeling and these changes were greater than those in the silent session. Heart rates (ΔHR) in the music session significantly decreased compared with those in the silent session. Other cardiac autonomic parameters such as high-frequency (HF) component and the ratio of low-frequency (LF) and HF components (LF/HF) were similar in the two sessions. In the linear regression analysis of the feelings with ΔHR and changes in LF/HF (ΔLF/HF), increases and decreases in ΔHR were correlated to the feeling axes of Fatigue-Healing and Anxiety/Tension-Security/Relaxation, whereas those in ΔLF/HF were related to the feeling axes

    Investigations on thermal comfort have attracted authors for years throughout the world and the most important findings are now the basis of international thermal comfort standards. There is little information available concerning occupant comfort and residential thermal environment in the intertropical sub-Saharan Africa. Thus the purpose for this study is to conduct a field study on comfort and residential thermal environments in a typical intertropical climatic region. A field survey has been conducted during the Harmattan season in two cities from the two climatic regions of Cameroon concerned by that wind. Specific study objectives were to evaluate and characterize some thermal perceptions of occupants in their residence, compare observed and predicted percent of dissatisfied, and discern differences between the study area and other climate zones where similar studies have been performed. It was found that the thermoneutral temperatures in both climatic regions range from 24.69 deg. C to 27.32 deg. C and, in traditional living room, it differs from that of modern living room with approximately 1 deg. C.

    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.

    Comfort plays an increasingly important role in the interior design of airplanes. Although ample research has been conducted on airplane design technology, only a small amount of public scientific information is available addressing the passenger's opinion. In this study, more than 10,000 internet trip reports and 153 passenger interviews were used to gather opinions about aspects which need to be improved in order to design a more comfortable aircraft interior. The results show clear relationships between comfort and legroom, hygiene, crew attention and seat/personal space. Passengers rate the newer planes significantly better than older ones, indicating that attention to design for comfort has proven effective. The study also shows that rude flight attendants and bad hygiene reduce the comfort experience drastically and that a high comfort rating is related to higher "fly again" values.

    Full Text Available We report the results of three high-powered replications of Troisi and Gabriel’s (2011 idea that writing about comfort food reduces feelings of loneliness amongst securely attached individuals after a belongingness threat. We conducted our studies amongst a large group of participants (Total N = 649 amongst American (MTurk, Dutch (Tilburg University; TiU, and Singaporean (Singapore Management University; SMU samples. Participants first completed an attachment style scale, followed by writing two essays for manipulating a sense of belongingness and salience of comfort food, and then reporting their loneliness levels. We did not confirm the overall effect over all three countries. However, exploratory results provide the preliminary suggestion that 1 the comfort food explanation likely holds amongst the American samples (including Troisi & Gabriel’s, but not amongst the TiU and SMU samples, and potentially that 2 the TiU and SMU participants self-regulate through warmer (vs. colder temperature foods. Both of these should be regarded with great caution as these analyses were exploratory, and because the Ns for the different temperature foods were small. We suspect we have uncovered first cross-cultural differences in self-regulation through food, but further confirmatory work is required to understand the cultural significance of comfort food for self-regulation.

    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.

    Sensations evoked by thermal stimulation (temperature-related sensations) can be divided into two categories, "temperature sensation" and "thermal comfort." Although several studies have investigated regional differences in temperature sensation, less is known about the sensitivity differences in thermal comfort for the various body regions. In the present study, we examined regional differences in temperature-related sensations with special attention to thermal comfort. Healthy male subjects sitting in an environment of mild heat or cold were locally cooled or warmed with water-perfused stimulators. Areas stimulated were the face, chest, abdomen, and thigh. Temperature sensation and thermal comfort of the stimulated areas were reported by the subjects, as was whole body thermal comfort. During mild heat exposure, facial cooling was most comfortable and facial warming was most uncomfortable. On the other hand, during mild cold exposure, neither warming nor cooling of the face had a major effect. The chest and abdomen had characteristics opposite to those of the face. Local warming of the chest and abdomen did produce a strong comfort sensation during whole body cold exposure. The thermal comfort seen in this study suggests that if given the chance, humans would preferentially cool the head in the heat, and they would maintain the warmth of the trunk areas in the cold. The qualitative differences seen in thermal comfort for the various areas cannot be explained solely by the density or properties of the peripheral thermal receptors and thus must reflect processing mechanisms in the central nervous system.

    to know the feelings of nurses regarding palliative care in adult intensive care units. qualitative study, which adopted the theoretical framework of Social Representations, carried out with 30 nurses of the state of Santa Catarina included by Snowball sampling. Data were collected through semi-structured interviews conducted from April to August 2015, organized and analyzed through the Collective Subject Discourse. the results showed how central ideas are related to feelings of comfort, frustration, insecurity and anguish, in addition to the feeling that the professional training and performance are focused on the cure. the social representations of nurses regarding the feelings related to palliative care are represented mainly by negative feelings, probably as consequence of the context in which care is provided.

    The objective of this study is to survey a nationally representative sample of obstetricians regarding comfort, knowledge, and practice patterns of caring for pregnant women after bariatric surgery. We conducted an online survey of US obstetricians and describe obstetrician's demographics, practice settings, and practice patterns. We assessed respondent's knowledge and recommended practices. We compared provider knowledge by years since completing residency, scope of practice (generalist or specialist), and practice setting (academic setting or other). Statistical significance was set at p < 0.05. A total of 106 completed the survey (response rate of 54%). Respondents had a median age of 47 and median 17 years in practice. Sixty-two percent were generalists. Nearly all of the respondents (94%) had some experience with caring for pregnant women after bariatric surgery and 83% reported feeling "very comfortable" (48%) or "somewhat comfortable" (35%) providing care for this population. Most (74%) were aware of increased risk of small for gestational age after surgery. Only 13% were able to correctly identify all recommended nutritional labs and 20% reported that they "did not know" which labs are recommended. There were no differences in comfort, experience, knowledge, and practice patterns by physician characteristics and practice settings. While most obstetricians are aware of perinatal risks after bariatric surgery, a substantial percentage of obstetricians are unaware of recommended practices regarding nutrition and nutritional monitoring. As bariatric surgery becomes increasingly prevalent among reproductive age women, educational interventions to increase obstetricians' knowledge of optimal care of pregnant women after bariatric surgery are urgently needed.

    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.

    ABSTRACT Background: Historically, medical students who are lesbian, gay, bisexual or transgendered (LGBT) report higher rates of social stress, depression, and anxiety, while LGBT patients have reported discrimination and poorer access to healthcare. Objective: The objectives of this study were: (1) to assess if medical students have perceived discrimination in their learning environment and; (2) to determine self-reported comfort level for caring for LGBT patients. Design: Medical students at the University of Ottawa (N = 671) were contacted via email and invited to complete a confidential web-based survey. Results: Response rate was 15.4% (103/671). This included 66 cis-gender heterosexuals (64.1%) and 37 LGBT students (35.9%). Anti-LGBT discrimination had been witnessed by 14.6% and heterosexism by 31.1% of respondents. Anti-LGBT discrimination most often originated from fellow medical students. Respondents who self-identified as LGBT were more likely to have perceived heterosexism (favoring opposite-sex relationships) (OR = 8.2, p LGBT discrimination (OR = 6.6, p = 0.002). While half of LGBT students shared their status with all classmates (51.4%), they were more likely to conceal this from staff physicians (OR = 27.2, p = 0.002). Almost half of medical students (41.7%) reported anti-LGBT jokes, rumors, and/or bullying by fellow medical students and/or other members of the healthcare team. Still, most respondents indicated that they felt comfortable with and capable of providing medical care to LGBT patients (≥83.5%), and were interested in further education around LGBT health issues (84.5%). Conclusion: Anti-LGBT discrimination and heterosexism are noted by medical students, indicating a suboptimal learning environment for LGBT students. Nonetheless, students report a high level of comfort and confidence providing health care to LGBT patients. PMID:28853327

    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.

    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.

    Promoting consistent and correct condom use remains a priority public health activity, although some HIV- and STI-related providers remain challenged by some men's resistance to condoms, which some claim do not fit properly or do not feel comfortable. Although these perceptions have been examined across multiple populations, they have not been documented among men living with HIV. During spring 2008, data were collected from 215 men living with HIV at HIV service organizations in the Midwestern and Southeastern United States. Participants completed the Condom Fit and Feel Scale and measures related to demographics and condom use during sexual interactions within the past 90 days. Men were primarily homosexual, African American, with a high school degree or higher, and unemployed. More than half of participants had used condoms for sexual intercourse within the previous 90 days. The majority of the men reported few problems with the fit and feel of condoms, with 63.1% reporting that condoms "fit my penis just fine," and 80.9% reported being able consistently to find condoms that they perceived to be "sized appropriately for my penis." Some men did report specific characteristics of condoms that challenged fit and feel, including 20.6% endorsing (always or often) that condoms feel too tight, 15.9% that condoms are too short, 17.8% or that condoms would not roll down far enough to cover their penis completely (15.6%). These data provide insights into mechanisms through which providers can help to increase men's access to the diverse range of condoms in the marketplace.

    The plumes from the Kuwait oil field fires reduced hemispheric (total) solar radiation by 26 36% during January June 1991 in Jubail (300 km SE of Kuwait City), Saudi Arabia. Residents feel noticeably cooler even though air temperatures have not been lowered significantly (up to June 1991). These observations support human comfort theories and demonstrate the importance of shade to comfort. The desirability of complete solar radiation measurements, including those of diffuse radiation, is indicated.

The rise of maize and soya-based vegetable oils have led to omega-6 fat overload and imbalance in the dietary ratio of omega-3 to omega-6 fats. This has led to toxicity studies with industrial trans fats; investigations on health risks associated with stress and comfort eating; and abdominal obesity. Other factors to consider are: diet, cholesterol and oxidative stress, as well as the new approaches to the chronology of eating and the health benefits of intermittent fasting.

    2010-01-01

    Thermal comfort--the state of mind, which expresses satisfaction with the thermal environment--is an important aspect of the building design process as modern man spends most of the day indoors. This paper reviews the developments in indoor thermal comfort research and practice since the second half of the 1990s, and groups these developments around two main themes; (i) thermal comfort models and standards, and (ii) advances in computerization. Within the first theme, the PMV-model (Predicted Mean Vote), created by Fanger in the late 1960s is discussed in the light of the emergence of models of adaptive thermal comfort. The adaptive models are based on adaptive opportunities of occupants and are related to options of personal control of the indoor climate and psychology and performance. Both models have been considered in the latest round of thermal comfort standard revisions. The second theme focuses on the ever increasing role played by computerization in thermal comfort research and practice, including sophisticated multi-segmental modeling and building performance simulation, transient thermal conditions and interactions, thermal manikins.

    In response to the Institute of Medicine (2011) report Occupational Health Nurses and Respiratory Protection: Improving Education and Training, a nationwide survey was conducted in May 2012 to assess occupational health nurses’ educational preparation, roles, responsibilities, and training needs in respiratory protection. More than 2,000 occupational health nurses responded; 83% perceived themselves as competent, proficient, or expert in respiratory protection, reporting moderate comfort with 12 respiratory program elements. If occupational health nurses had primary responsibility for the respiratory protection program, they were more likely to perceive higher competence and more comfort in respiratory protection, after controlling for occupational health nursing experience, highest education, occupational health nursing certification, industry sector, Association of Occupational Health Professionals in Healthcare membership, taking a National Institute for Occupational Safety and Health spirometry course in the prior 5 years, and perceiving a positive safety culture at work. These survey results document high perceived competence and comfort in respiratory protection. These findings support the development of targeted educational programs and interprofessional competencies for respiratory protection. PMID:23429638

    A new control strategy was developed based on the application of wireless sensor network with the connection to a smart grid to investigate if it is possible to save energy on the level of the user under the condition of maintaining the same or even improved level of individual comfort. By using different scenarios, for individual comfort and energy consumption, agents provide the steering of the process control This forms the basis of a new approach to optimize the energy consumption, after which the effect of it can be used on the level of residential building to optimize the interaction with the electrical infrastructure, the smart grid. [Dutch] Er vindt onderzoek plaats naar een nieuwe regelstrategie gebaseerd op de toepassing van een draadloos sensor netwerk dat is gekoppeld aan het smart grid. Doel van deze regelstrategie is om op gebruikersniveau energie te kunnen besparen met behoud of zelfs verbetering van het individueel comfort. Er zijn verschillende scenario's voor individueel comfort en energiegebruik van apparatuur met behulp van agents die voor de aansturing kunnen zorgen. Zo wordt de kern van de energievraag geoptimaliseerd. De doorwerking hiervan tot op het niveau van woninggebouw en de koppeling met het externe elektriciteitsnet kan vervolgens worden geoptimaliseerd.

    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 In the article, I will argue that metacognition plays an important role in decision-making not only as direct online monitoring and control of decision-making processes but also by enabling us to influence our decisions and actions - and mental states and processes, related to them - in an offline manner. That is, offline metacognition allows us to observe, refer to and, to a certain degree, exert influence on mental states and processes related to our decisions and actions in the way of being removed, decoupled from the task/decision at hand and present time demands. As such, it enables us to observe, form thoughts and have feelings about mental states and processes directly related to our future decisions, to plan our future decisions, to reflect on our past choices, and to think and have feelings about our broader goals, desires, and personal values that are indirectly related to our decisions. To illustrate the importance of offline metacognition in decision-making, I will firstly review and discuss some experimental findings on implementation intentions ("decisions about the future" and anticipated emotions (beliefs about future emotional states related to outcomes of our decisions. Secondly, I will argue that our ability to reflect (think and feel on our broader goals, desires and personal values - that represent a kind of structure into which our specific decisions are embedded - reveals how offline metacognition can exert influence on our decisions also in an indirect way. All in all, I will try to show that our ability to refer to our own minds in an offline way - be it to mental states and processes directly or indirectly related to specific decisions - is essential for us to decide, as we decide, and act, as we act.

  13. 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

    2012-01-01

    There are many references to the WHO guidance on thermal comfort in housing, but not to the original source material. Based on archive material, this paper gives the evidential basis for the WHO guidance. It then reports on evidence that some groups may be more susceptible to high or low indoor temperatures than others. It examines different methods for measuring thermal comfort, such as air temperature measurement, assessing residents' perception, and predicting satisfaction. Resident's perception was used effectively in the WHO LARES project, showing that self-reported poor health was significantly associated with poor thermal comfort. Tools to inform strategies directed at dealing with cold homes and fuel poverty are considered, including Energy Performance Certificates, Fuel Poverty Indicators, and the English Housing Health and Safety Rating System. Conclusions from a WHO Workshop on Housing, Energy and Thermal Comfort are also summarised. The WHO view of thermal comfort, which is driven by protecting health from both high and low indoor temperatures, should be recognised in energy efficiency, fuel poverty and climate change strategies. While this is a major challenge, it could provide both health gains for individuals, and economic benefits for society. - Highlights: ► WHO guidance on thermal comfort is directed to protecting health in the home environment. ► In particular, the WHO guidance aims to protect the health of the most susceptible and fragile. ► Housing energy efficiency strategies protect health, and attack inequities. ► Housing energy efficiency strategies also have economic benefits for society.

    Purpose To determine factors associated with students’ comfort in addressing patients’ sexuality in the clinical context. Method The authors invited students enrolled in MD-degree-granting and osteopathic medical schools in the United States and Canada to participate in an anonymous Internet survey between February and July 2008. The survey assessed ethnodemographic factors and sexual history. Respondents also completed the Center for Epidemiologic Studies Depression Scale. Male respondents completed the International Index of Erectile Function and the Premature Ejaculation Diagnostic Tool. Female respondents completed the Female Sexual Function Index and the Index of Sex Life. The authors used descriptive statistics, ANOVA, and multivariable logistic regression to analyze responses. Results The authors’ analyses included 2,261 completed survey responses: 910 from men, 1,343 from women, and 8 from individuals who self-identified as “other” gendered. Over 53% of respondents (n = 1,206) stated that they felt they had not received sufficient training in medical school to address sexual concerns clinically. Despite this, 81% of students (n = 1,827) reported feeling comfortable dealing with their patients’ sexuality issues. Students with limited sexual experience, students at risk for sexual problems, and students who felt that they had not been trained adequately were less likely to report being comfortable talking to patients about sexual health issues. Conclusions Perception of inadequate sexuality training in medical school and personal issues pertaining to sex may be associated with students’ difficulty in addressing patients’ sexuality. Adequate training is preeminently associated with feeling comfortable addressing patients’ sexuality and should be a priority for medical education. PMID:20671459

    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.

    Early investigations of guilt cast it as an emotion that prompts broad reparative behaviors that help guilty individuals feel better about themselves or about their transgressions. The current investigation found support for a more recent representation of guilt as an emotion designed to identify and correct specific social offenses. Across five experiments, guilt influenced behavior in a targeted and strategic way. Guilt prompted participants to share resources more generously with others, but only did so when those others were persons whom the participant had wronged and only when those wronged individuals could notice the gesture. Rather than trigger broad reparative behaviors that remediate one’s general reputation or self-perception, guilt triggers targeted behaviors intended to remediate specific social transgressions.

    The purpose of the study was to examine the relationship between ethnicity, the presence of moderate to severe symptoms of depression, and communication about emotions and feelings during prenatal visits. The purpose was also to describe women's perceptions of the barriers to communicating with providers, family, and friends about their emotions or feelings and how to overcome these barriers. Seventy-three women were recruited and interviewed by a bilingual research assistant between June and September 2002 after a prenatal visit occurring between 12- and 32-week gestation. Nineteen percent of women screened as having moderate to severe symptoms of depression. Quality of social relationships had a significant negative relationship with whether women had moderate to severe symptoms of depression. Almost 29% of women reported discussing their emotions or feelings with their providers and this did not differ significantly by ethnicity. Women who discussed their emotions or feelings with their providers did have significantly higher scores on the Beck Depression Inventory-II (BDI-II) than those who did not. Thirty-four percent of women stated that there were barriers to expectant or new mothers communicating with their providers. Women who felt that there were barriers to expectant or new mothers discussing their emotions with their providers did have significantly higher BDI-II scores than those women who did not. Thirty-seven percent of women believed that there were barriers to expectant or new mothers communicating with their family about their emotions. Women felt that providers and families could try to develop trust with them and try to make them feel more comfortable discussing their feelings.

    The goal of this project was the development of a set of tools for the selection of optimal concepts for HVAC-systems in housing buildings. Several factors are considered. They include technical feasibility, costs for investment, maintenance and operation, energy concumption, environmental impacts and user comfort. It is intended with the help of these tools to identify the most important factors which influence energy consumption and to suggest simple and cost effective measures to reduce energy consumption. Measures include improvements of the envelope, changes in the HVAC-system and its operation according to the needs to the inhabitants of the building. This report describes these components of this tool set which were developed in the frame of the project WohnKomfort. It lists data and rules chosen. In addition we report experiences which we gained with an prototypical implementation. This implementation allows load calculations for more than 60.000 different buildings applying EN 802 (only one zone model) as calculation method. It also supports selection of heating systems for such buildings by offering an evaluation according to user specified criteria including cost, environment and comfort.

  3. Leading by feel.

    Science.gov (United States)

    2004-01-01

    Like it or not, leaders need to manage the mood of their organizations. The most gifted leaders accomplish that by using a mysterious blend of psychological abilities known as emotional intelligence. They are self-aware and empathetic. They can read and regulate their own emotions while intuitively grasping how others feel and gauging their organization's emotional state. But where does emotional intelligence come from, and how do leaders learn to use it? In this article, 18 leaders and scholars (including business executives, leadership researchers, psychologists, an autism expert, and a symphony conductor) explore the nature and management of emotional intelligence--its sources, uses, and abuses. Their responses varied, but some common themes emerged: the importance of consciously--and conscientiously--honing one's skills, the double-edged nature of self-awareness, and the danger of letting any one emotional intelligence skill dominate. Among their observations: Psychology professor John Mayer, who co-developed the concept of emotional intelligence, warns managers not to be confused by popular definitions of the term, which suggest that if you have a certain set of personality traits then you automatically possess emotional intelligence. Neuropsychologist Elkhonon Goldberg agrees with professors Daniel Goleman and Robert Goffee that emotional intelligence can be learned--but only by people who already show an aptitude for it. Cult expert Janja Lalich points out that leaders can use their emotional intelligence skills for ill in the same way they can for good. "Sometimes the only difference is [the leader's] intent," she says. And business leaders Carol Bartz, William George, Sidney Harman, and Andrea jung (of Autodesk, Medtronic, Harman International, and Avon respectively) describe situations in which emotional intelligence traits such as self-awareness and empathy have helped them and their companies perform at a higher level.

  4. 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.

    This paper deals with thermal comfort in urban transitional spaces. This topic investigates thermal comfort during walking activities through transitional spaces-urban corridors, shopping streets, and open-ended passageways. The study involves a field study and a laboratory study with a sequenced walk through an environmental control chamber. Subjects in both studies wore the same clothing ensembles, walked the same speed, and evaluated their thermal comfort at 20 designated point in the field and in specific rooms in the control chamber. Air temperature, relative humidity, and air velocity were measured concurrently as the thermal comfort votes completed. Findings revealed that the previously experienced temperatures determined thermal comfort at the following point in the sequence. Because thermal comfort at a point can be influenced widely by relative placement of temperatures in sequence, thermal comfort in transitional spaces can be adapted very widely compared to comfort inside of buildings. Thermal comfort along the experimental courses was evaluated by averaging the temperature of a course. (author)

    In this experiment, a method of questionnaire survey was adopted. By changing the air flow rate under the indoor and outdoor natural conditions, the subjective Thermal Sensation Vote (TSV) and the Thermal Comfort Vote (TCV) were recorded. The draft sensation can reduce the thermal sensation, but the draft sensation can cause discomfort, and the thermal comfort in a windy environment is lower than in a windless environment. When the temperature rises or the level of human metabolism increases, the person feels heat, the demand for draft sensation increases, and the uncomfortable feeling caused by the draft sensation may be reduced. Increasing the air flow within a certain range can be used to compensate for the increase in temperature.

    Full Text Available Color preferences in engineering are very important, and there exists relationship between color preference and visual comfort. In this study, there are thirty university students who participated in the experiment, supplemented by pre- and posttest questionnaires, which lasted about an hour. The main purpose of this study is to explore the visual effects of different color assignment with subjective color preferences via eye tracking technology. Eye-movement data through a nonlinear analysis detect slight differences in color preferences and visual comfort, suggesting effective physiological indicators as extensive future research discussed.

    The purpose of the present study was to describe effective nursing care through evaluation of a nursing intervention that enhanced acceptance of pregnancy and focused on a comfortable experience for pregnant women. Thirty-two subjects who were expected to have a normal pregnancy were assigned into either the intervention or the control group. The nursing intervention consisted of the use of a pregnancy diary and four interviews, two of which were held in the first trimester, one in the second and one in the third trimester. The nursing care given was recorded in tapes and field notes. The data were analyzed using a qualitative content analysis method. As a result of analyzing the nursing care of 13 women pregnant for the first time who were provided with nursing intervention, the following seven categories of nursing care were extracted for the intervention: encouragement of women to record their experiences using a pregnancy diary; recognizing and acknowledging negative feelings; reducing the negative aspects of pregnancy and reframing; expression and reinforcement of positive feelings; clarification and reinforcement of positive meanings; awareness of own comfortable experiences; promotion of diverse comfortable aspects and continuation of comfortable experiences. The seven nursing care interventions were effective in increasing the comfortable experiences of pregnant women and enhancing a positive attitude towards pregnancy. Nursing intervention can aid in enhancing positivity and comfort in pregnant women. Furthermore, this nursing intervention can be applied to adolescents, socially disadvantaged pregnant women, and hospitalized women.

  1. Understanding the adaptive approach to thermal comfort

    This paper explains the adaptive approach to thermal comfort, and an adaptive model for thermal comfort is presented. The model is an example of a complex adaptive system (Casti 1996) whose equilibria are determined by the restrictions acting upon it. People`s adaptive actions are generally effective in securing comfort, which occurs at a wide variety of indoor temperatures. These comfort temperatures depend upon the circumstances in which people live, such as the climate and the heating or cooling regime. The temperatures may be estimated from the mean outdoor temperature and the availability of a heating or cooling plant. The evaluation of the parameters of the adaptive model requires cross-sectional surveys to establish current norms and sequential surveys (with and without intervention) to evaluate the rapidity of people`s adaptive actions. Standards for thermal comfort will need revision in the light of the adaptive approach. Implications of the adaptive model for the HVAC industry are noted.

    Full Text Available To protect humans from heat stress risks, thermal comfort and heat stress potential were evaluated under arid environment, which had never been made for such climate. The thermal indices THI, WBGT, PET, and UTCI were used to evaluate thermal comfort and heat stress. RayMan software model was used to estimate the PET, and the UTCI calculator was used for UTCI. Dry and wet bulb temperatures (Td, Tw, natural wet bulb temperature (Tnw, and globe temperature (Tg were measured in a summer day to be used in the calculation. The results showed the following. (i The thermal sensation and heat stress levels can be evaluated by either the PET or UTCI scales, and both are valid for extremely high temperature in the arid environment. (ii In the comfort zone, around 75% of individuals would be satisfied with the surrounding environment and feel comfortable during the whole day. (iii Persons are exposed to strong heat stress and would feel uncomfortable most of the daytime in summer. (iv Heat fatigue is expected with prolonged exposure to sun light and activity. (v During the daytime, humans should schedule their activities according to the highest permissible values of the WBGT to avoid thermal shock.

    Full Text Available The development of green space along urban rivers could mitigate urban heat island effects, enhance the physical and mental well-being of city dwellers, and improve flood resilience. A linear park has been recently created along the ephemeral Pedieos River in the urban area of Nicosia, Cyprus. Questionnaire surveys and micrometeorological measurements were conducted to explore people’s perceptions and satisfaction regarding the services of the urban park. People’s main reasons to visit the park were physical activity and exercise (67%, nature (13%, and cooling (4%. The micrometeorological measurements in and near the park revealed a relatively low cooling effect (0.5 °C of the park. However, the majority of the visitors (84% were satisfied or very satisfied with the cooling effect of the park. Logistic regression analysis indicated that the odds of individuals feeling very comfortable under a projected 3 °C future increase in temperature would be 0.34 times lower than the odds of feeling less comfortable. The discrepancies between the observed thermal comfort index and people’s perceptions revealed that people in semi-arid environments are adapted to the hot climatic conditions; 63% of the park visitors did not feel uncomfortable at temperatures between 27 °C and 37 °C. Further research is needed to assess other key ecosystems services of this urban green river corridor, such as flood protection, air quality regulation, and biodiversity conservation, to contribute to integrated climate change adaptation planning.

    Studies concerning indoor thermal conditions are very important in defining the satisfactory comfort range in health care facilities. This study focuses on the evaluation of the thermal comfort sensation felt by surgeons and nurses, in an orthopaedic surgical room of a Portuguese hospital. Two cases are assessed, with and without the presence of a person. Computational fluid dynamic (CFD) tools were applied for evaluating the predicted mean vote (PMV) index locally. Using average ventilation values to calculate the PMV index does not provide a correct and enough descriptive evaluation of the surgical room thermal environment. As studied for both cases, surgeons feel the environment slightly hotter than nurses. The nurses feel a slightly cold sensation under the air supply diffuser and their neutral comfort zone is located in the air stagnation zones close to the walls, while the surgeons feel the opposite. It was observed that the presence of a person in the room leads to an increase of the PMV index for surgeons and nurses. That goes in line with the empirical knowledge that more persons in a room lead to an increased heat sensation. The clothing used by both classes, as well as the ventilation conditions, should be revised accordingly to the amount of persons in the room and the type of activity performed.

    A challenge for electric buses is to minimize heating and cooling power to maximally extend the driving range, but still provide sufficient thermal comfort for the driver and passengers. Therefore, we investigated the thermal sensation (TS) and thermal comfort (TC) of passengers in buses during a cool day (temperature 13.4 ± 0.5 °C, relative humidity (RH) 60 ± 5.8%) typical for the Dutch temperate maritime climate. 28 Males and 72 females rated TS and TC and gave information on age, stature, body weight and worn garments. The temperature in the bus of 22.5 ± 1.1 °C and RH of 59.9 ± 5.8% corresponded to a slightly warm feeling (TS = 0.85 ± 1.06) and TC of 0.39 ± 0.65. TS related significantly to bus temperature, clothing insulation and age. Linear regression based on these parameters showed that the temperature in the bus corresponding to TC = 0 and TS = 0 would have been 20.9 ± 0.6 °C. In conclusion, a 1.6 °C lower bus temperature during the investigated cool day probably would have led to less thermal discomfort and energy savings of electrical busses. The methodology to relate climatic measurements to subjective assessments is currently employed in a wider climatic range and may prove to be useful to find a better balance between thermal comfort and energy savings of the bus.

    Hospital patients experience significant pain, which can delay healing and increase the risk of developing chronic pain. Nurses are affected by patients' ongoing pain and may cope with consequent anxiety and helplessness by distancing themselves from such patients. Understanding nurses' responses to patients in severe pain will inform strategies to support their coping, their patients and, ultimately, their retention in the nursing workforce. The aim of the study was to develop a substantive theory explaining the hospital nurse's perspective of caring for patients in severe pain. The study used grounded theory method. Data were collected on four acute care wards in a 610 bed Australian hospital. The sample included 33 nurse participants and 11 patient participants. Selection criteria for nurse participants were those who worked in the four study wards, cared for patients who experienced severe pain, and consented to be included. Selection criteria for patient participants were those who self-reported pain at intensity of seven or more on a scale of 0-10, were aged 18 years or older, could speak and read English, and consented to be included. Theoretical sampling directed the collection of data using semi-structured interviews with nurses and participant observation, including structured observations of nurses who cared for patients in pain. Data were analysed using constant comparison method. Nurse participants encountered a basic psychosocial problem of feelings of disempowerment when their patients experienced persisting severe pain. In response, they used a basic psychosocial process of seeking empowerment to provide comfort in order to resolve distress and exhaustion associated with disempowerment. This coping process comprised three stages: building connections; finding alternative ways to comfort; and quelling emotional turmoil. The substantive theory proposed a link between the stress of nurses' disempowerment and a coping response that provides direction to

    2008-01-01

    We report a new investigation into how surface topography and friction affect human touch–feel perception. In contrast with previous work based on micro-scale mapping of surface mechanical and tribological properties, this investigation focuses on the direct measurement of the friction generated when a fingertip is stroked on a test specimen. A special friction apparatus was built for the in situ testing, based on a linear flexure mechanism with both contact force and frictional force measured simultaneously. Ten specimens, already independently assessed in a 'perception clinic', with materials including natural wood, leather, engineered plastics and metal were tested and the results compared with the perceived rankings. Because surface geometrical features are suspected to play a significant role in perception, a second set of samples, all of one material, were prepared and tested in order to minimize the influence of properties such as hardness and thermal conductivity. To minimize subjective effects, all specimens were also tested in a roller-on-block configuration based upon the same friction apparatus, with the roller materials being steel, brass and rubber. This paper reports the detailed design and instrumentation of the friction apparatus, the experimental set-up and the friction test results. Attempts have been made to correlate the measured properties and the perceived feelings for both roughness and friction. The results show that the measured roughness and friction coefficient both have a strong correlation with the rough–smooth and grippy–slippery feelings

  11. (The feeling of) meaning-as-information.

    2014-05-01

    The desire for meaning is recognized as a central human motive. Yet, knowing that people want meaning does not explain its function. What adaptive problem does this experience solve? Drawing on the feelings-as-information hypothesis, we propose that the feeling of meaning provides information about the presence of reliable patterns and coherence in the environment, information that is not provided by affect. We review research demonstrating that manipulations of stimulus coherence influence subjective reports of meaning in life but not affect. We demonstrate that manipulations that foster an associative mindset enhance meaning. The meaning-as-information perspective embeds meaning in a network of foundational functions including associative learning, perception, cognition, and neural processing. This approach challenges assumptions about meaning, including its motivational appeal, the roles of expectancies and novelty in this experience, and the notion that meaning is inherently constructed. Implications for constructed meaning and existential meanings are discussed.

    Full Text Available In today’s automotive market, comfort is huge selling point of a vehicle. Priority is given by buyers to how comfortable a seat feels during purchase decisions. The measure of comfort is harmonious mix of many aspects such as human ergonomics and physiological factors. However, a gap still exists between objective and subjective measures due to lack of emphasis by past researchers. This is particularly obvious in the lumbar support feature that has still not been able to address the health problems related to driving. This project focuses on bridging the gap by giving users the ability to define true preferred posture in realistic settings. This is done by the creation of a apparatus that allows users to individually manipulate the seat contour for optimum support in more segments than just lumbar area. The experiment is performed in 3 parts, where in each part different segments of the apparatus are manipulatable (lumbar segment, sacral & thoracic segment, and all segments. Sixty human subjects’ statistics are recorded (gender, age, BMI and height and the subjects are palpated to locate internal joints. These joints are marked and postural angles between them are measured using a goniometer. In each seat configuration, the angles are measured and a comfort rating is taken to be compared. It was found that the posture angles are different among the 3 experiments, and there is a change in comfort felt. Some human factors have also been proven to contribute heavily to angles chosen by occupants.

    Comfort is indispensable to make a friendly neighborhood or city. Especially the comfort of the infrastructure in the corridor. People must be able to feel comfortable to act rationally in their physical environment. Existing infrastructure must able to support Kesawan as a historic district. Kesawan is an area that is filled with so many unique buildings. Without comfort, how good the existing buildings’ architecture cannot be enjoyed. It will also affect the identity of a region or city. The aim of this research is to re-design the public facilities from Kesawan corridor’s comfort aspect: orientation, traffic calming, vegetation, signage, public facilities (toilet, seating place, bus station, bins), information center, parking and pedestrian path. It will translate the design concept in the form of design criteria. This research uses qualitative methods. Some facilities in this corridor are unsuitable even some of them are not available. So, we need some improvements and additions to the existing facilities. It is expected that by upgrading the existing facilities, visitors who come to Kesawan will be able to enjoy more and able to make Medan city more friendly.

    In a previous study, we investigated the contribution of the surface of the face, chest, abdomen, and thigh to thermal comfort by applying local temperature stimulation during whole-body exposure to mild heat or cold. In hot conditions, humans prefer a cool face, and in cold they prefer a warm abdomen. In this study, we extended investigation of regional differences in thermal comfort to the neck, hand, soles, abdomen (Experiment 1), the upper and lower back, upper arm, and abdomen (Experiment 2). The methodology was similar to that used in the previous study. To compare the results of each experiment, we utilized the abdomen as the reference area in these experiments. Thermal comfort feelings were not particularly strong for the limbs and extremities, in spite of the fact that changes in skin temperature induced by local temperature stimulation of the limbs and extremities were always larger than changes that were induced in the more proximal body parts. For the trunk areas, a significant difference in thermal comfort was not observed among the abdomen, and upper and lower back. An exception involved local cooling during whole-body mild cold exposure, wherein the most dominant preference was for a warmer temperature of the abdomen. As for the neck and abdomen, clear differences were observed during local cooling, while no significant difference was observed during local warming. We combined the results for the current and the previous study, and characterized regional differences in thermal comfort and thermal preference for the whole-body surface.

    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.

    2015-09-01

    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.

    Patients with Alzheimer disease (AD) typically have impaired declarative memory as a result of hippocampal damage early in the disease. Far less is understood about AD's effect on emotion. We investigated whether feelings of emotion can persist in patients with AD, even after their declarative memory for what caused the feelings has faded. A sample of 17 patients with probable AD and 17 healthy comparison participants (case-matched for age, sex, and education) underwent 2 separate emotion induction procedures in which they watched film clips intended to induce feelings of sadness or happiness. We collected real-time emotion ratings at baseline and at 3 post-induction time points, and we administered a test of declarative memory shortly after each induction. As expected, the patients with AD had severely impaired declarative memory for both the sad and happy films. Despite their memory impairment, the patients continued to report elevated levels of sadness and happiness that persisted well beyond their memory for the films. This outcome was especially prominent after the sadness induction, with sustained elevations in sadness lasting for more than 30 minutes, even in patients with no conscious recollection for the films. These findings indicate that patients with AD can experience prolonged states of emotion that persist well beyond the patients' memory for the events that originally caused the emotion. The preserved emotional life evident in patients with AD has important implications for their management and care, and highlights the need for caretakers to foster positive emotional experiences.

    Which emotional experiences should people pursue to optimize happiness? According to traditional subjective well-being research, the more pleasant emotions we experience, the happier we are. According to Aristotle, the more we experience the emotions we want to experience, the happier we are. We tested both predictions in a cross-cultural sample of 2,324 participants from 8 countries around the world. We assessed experienced emotions, desired emotions, and indices of well-being and depressive symptoms. Across cultures, happier people were those who more often experienced emotions they wanted to experience, whether these were pleasant (e.g., love) or unpleasant (e.g., hatred). This pattern applied even to people who wanted to feel less pleasant or more unpleasant emotions than they actually felt. Controlling for differences in experienced and desired emotions left the pattern unchanged. These findings suggest that happiness involves experiencing emotions that feel right, whether they feel good or not. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    We wanted to compare 2 screening instruments for problem drinking, the CAGE and a single question, assessing frequency of use, patient and clinician comfort, and patient engagement in change. The study was a crossover, cluster-randomized clinical trial with 31 clinicians in Missouri and 13 in the American Academy of Family Physicians (AAFP) National Network for Family Practice and Primary Care Research; 2,800 patients provided data. The clinician was the unit of randomization. Clinicians decided whether to screen each patient; if they chose to screen, they used the screening approach assigned for that block of patients. The clinician and patient separately completed questionnaires immediately after the office visit to assess each one's comfort with screening (and any ensuing discussion) and the patient's engagement in change. Missouri clinicians screened more patients when assigned the single question (81%) than the CAGE (69%, P = .001 in weighted analysis). There was no difference among AAFP network clinicians (96% of patients screened with the CAGE, 97% with the single question). Eighty percent to 90% of clinicians and 70% of patients reported being comfortable with screening and the ensuing discussion, with no difference between approaches in either network. About one third of patients who were identified as problem drinkers reported thinking about or planning to change their drinking behavior, with no difference in engagement between screening approaches. Clinicians and patients reported similar comfort with the CAGE questions and the single-question screening tools for problem drinking, and the 2 instruments were equal in their ability to engage the patient. In Missouri, the single question was more likely to be used.

    Love feelings can be more intense than desired (e.g., after a break-up) or less intense than desired (e.g., in long-term relationships). If only we could control our love feelings! We present the concept of explicit love regulation, which we define as the use of behavioral and cognitive strategies to change the intensity of current feelings of romantic love. We present the first two studies on preconceptions about, strategies for, and the feasibility of love regulation. Questionnaire responses showed that people perceive love feelings as somewhat uncontrollable. Still, in four open questions people reported to use strategies such as cognitive reappraisal, distraction, avoidance, and undertaking (new) activities to cope with break-ups, to maintain long-term relationships, and to regulate love feelings. Instructed up-regulation of love using reappraisal increased subjective feelings of attachment, while love down-regulation decreased subjective feelings of infatuation and attachment. We used the late positive potential (LPP) amplitude as an objective index of regulation success. Instructed love up-regulation enhanced the LPP between 300-400 ms in participants who were involved in a relationship and in participants who had recently experienced a romantic break-up, while love down-regulation reduced the LPP between 700-3000 ms in participants who were involved in a relationship. These findings corroborate the self-reported feasibility of love regulation, although they are complicated by the finding that love up-regulation also reduced the LPP between 700-3000 ms in participants who were involved in a relationship. To conclude, although people have the preconception that love feelings are uncontrollable, we show for the first time that intentional regulation of love feelings using reappraisal, and perhaps other strategies, is feasible. Love regulation will benefit individuals and society because it could enhance positive effects and reduce negative effects of romantic

    For a population of interacting self-interested agents, we study how the average cooperation level is affected by some individuals' feelings of being betrayed and guilt. We quantify these feelings as adjusted payoffs in asymmetric games, where for different emotions, the payoff matrix takes the structure of that of either a prisoner's dilemma or a snowdrift game. Then we analyze the evolution of cooperation in a well-mixed population of agents, each of whom is associated with such a payoff matrix. At each time-step, an agent is randomly chosen from the population to update her strategy based on the myopic best-response update rule. According to the simulations, decreasing the feeling of being betrayed in a portion of agents does not necessarily increase the level of cooperation in the population. However, this resistance of the population against low-betrayal-level agents is effective only up to some extend that is explicitly determined by the payoff matrices and the number of agents associated with these matrices. Two other models are also considered where the betrayal factor of an agent fluctuates as a function of the number of cooperators and defectors that she encounters. Unstable behaviors are observed for the level of cooperation in these cases; however, we show that one can tune the parameters in the function to make the whole population become cooperative or defective.

    2001-01-01

    The present paper presents a thermodynamic approach to assess the quality of human-thermal environment interaction and quantify thermal comfort. The approach involves development of entropy generation term by applying second law of thermodynamics to the combined human-environment system. The entropy generation term combines both human thermal physiological responses and thermal environmental variables to provide an objective measure of thermal comfort. The original concepts and definitions form the basis for establishing the mathematical relationship between thermal comfort and entropy generation term. As a result of logic and deterministic approach, an Objective Thermal Comfort Index (OTCI) is defined and established as a function of entropy generation. In order to verify the entropy-based thermal comfort model, human thermal physiological responses due to changes in ambient conditions are simulated using a well established and validated human thermal model developed at the Institute of Environmental Research of Kansas State University (KSU). The finite element based KSU human thermal computer model is being utilized as a "Computational Environmental Chamber" to conduct series of simulations to examine the human thermal responses to different environmental conditions. The output from the simulation, which include human thermal responses and input data consisting of environmental conditions are fed into the thermal comfort model. Continuous monitoring of thermal comfort in comfortable and extreme environmental conditions is demonstrated. The Objective Thermal Comfort values obtained from the entropy-based model are validated against regression based Predicted Mean Vote (PMV) values. Using the corresponding air temperatures and vapor pressures that were used in the computer simulation in the regression equation generates the PMV values. The preliminary results indicate that the OTCI and PMV values correlate well under ideal conditions. However, an experimental study

    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.

    With respect to the perceived thermal comfort there are large individual differences, which also change during daytime. Therefore is worthwhile to determine the individual thermal comfort profiles during the day. The perceived thermal comfort level follows an individual day profile. By using these profiles as a leading principal to control the indoor temperatures an improvement of the perceived comfort is possible while at the same time it can reduce energy consumption.

    Full Text Available Thermal comfort is of great importance in preserving body temperature homeostasis during thermal stress conditions. Although the thermal comfort of horses has been widely studied, there is no report of its relationship with surface temperature (T S. This study aimed to assess the potential of data mining techniques as a tool to associate surface temperature with thermal comfort of horses. T S was obtained using infrared thermography image processing. Physiological and environmental variables were used to define the predicted class, which classified thermal comfort as "comfort" and "discomfort". The variables of armpit, croup, breast and groin T S of horses and the predicted classes were then subjected to a machine learning process. All variables in the dataset were considered relevant for the classification problem and the decision-tree model yielded an accuracy rate of 74 %. The feature selection methods used to reduce computational cost and simplify predictive learning decreased model accuracy to 70 %; however, the model became simpler with easily interpretable rules. For both these selection methods and for the classification using all attributes, armpit and breast T S had a higher power rating for predicting thermal comfort. Data mining techniques show promise in the discovery of new variables associated with the thermal comfort of horses.

    Building Energy Simulation (BES) programmes often use conventional thermal comfort theories to make decisions, whilst recent research in the field of thermal comfort clearly shows that important effects are not incorporated. The conventional theories of thermal comfort were set up based on steady state laboratory experiments. This, however, is not representing the real situation in buildings, especially not when focusing on residential buildings. Therefore, in present analysis, recent reviews and adaptations are considered to extract acceptable temperature ranges and comfort scales. They will be defined in an algorithm, easily implementable in any BES code. The focus is on comfortable temperature levels in the room, more than on the detailed temperature distribution within that room. (author)

    Full Text Available Although there is extensive literature regarding sex differences in jealousy due to infidelity, guilt resulting from infidelity remains unexplored. We hypothesize that men will feel guiltier from imagined emotional rather than sexual infidelity, as it is most important for their partner's reproductive success. Similarly, we predict that women will feel more guilt from imagined sexual rather than emotional infidelity. The findings indicate a different pattern; men feel guiltier following sexual infidelity, whereas women feel guiltier following emotional infidelity. Results also show that both sexes believe their partners would have a more difficult time forgiving sexual, rather than emotional, infidelity, but women and not men report that sexual infidelity would more likely lead to relationship dissolution. These findings are discussed in view of evolved mating strategies and individual reproductive success.

    2003-03-01

    During a unimanual grip selection task in which people pick up a lightweight dowel and place one end against targets at variable heights, the choice of hand grip (overhand vs. underhand) typically depends on the perception of how comfortable the arm will be at the end of the movement: an end-state comfort effect. The two experiments reported here extend this work to bimanual tasks. In each experiment, 26 right-handed participants used their left and right hands to simultaneously pick up two wooden dowels and place either the right or left end against a series of 14 targets ranging from 14 to 210 cm above the floor. These tasks were performed in systematic ascending and descending orders in Experiment 1 and in random order in Expiment 2. Results were generally consistent with predictions of end-state comfort in that, for the extreme highest and lowest targets, participants tended to select opposite grips with each hand. Taken together, our findings are consistent with the concept of constraint hierarchies within a posture-based motion-planning model.

    The world has started to feel the impact of a global chronic disease epidemic, which is putting pressure on our health care systems. If uncurbed, a new generation of "diseases of comfort" (such as those chronic diseases caused by obesity and physical inactivity) will become a major public health problem in this and the next century. To describe the concept, causes, and prevention and control strategies of diseases of comfort. Brokered by a senior research scientist specialised in knowledge translation, a chair, a president, and a past president of national public health associations contributed their views on the subject. Diseases of comfort have emerged as a price of living in a modern society. It is inevitable that these diseases will become more common and more disabling if human "progress" and civilisation continue toward better (more comfortable) living, without necessarily considering their effects on health. Modern technology must be combined with education, legislation, intersectoral action, and community involvement to create built and social environments that encourage, and make easy, walking, physical activity, and nutritious food choices, to reduce the health damaging effects of modern society for all citizens and not only the few. Public health needs to be more passionate about the health issues caused by human progress and adopt a health promotion stance, challenging the assumptions behind the notion of social "progress" that is giving rise to the burden of chronic disease and developing the skills to create more health promoting societies in which individual health thrives.

    Background: Ophthalmological conditions are frequently encountered in almost all clinical specialties. Assessing the adequacy of ophthalmology teaching in undergraduate medical education is important in order to diagnose and manage different ophthalmological conditions. The objective of this study was to determine the comfort level of post graduate residents working in different clinical domains in managing common ophthalmic conditions. Methods: A cross sectional survey involving 277 post graduate residents was carried out over a period of six months in both private and public tertiary care hospital. A questionnaire containing two sections and 17 variables in total were distributed among Medical Residents of different specialties except ophthalmology residents. Participants of the study were selected through consecutive non probability sampling. Results: Mean hours of classroom based ophthalmology instruction during during undergraduate program was 59.38 hours (55.9) and mean hours of clinical based ophthalmology instruction during undergraduate program was 62.73 hours (60.8) 54 percentage were either not comfortable or somewhat comfortable in managing common ophthalmic condition. Conclusion: Teaching hours in under graduate program meet or exceed requisite criteria. However graduating doctors generally feel that the time spent does not provide them with the comfort and skill level required to care for patients with ocular presentations. (author)

  8. Contribution of Portuguese Vernacular Building Strategies to Indoor Thermal Comfort and Occupants’ Perception

    Directory of Open Access Journals (Sweden)

    Jorge Fernandes

    2015-11-01

    Full Text Available Solar passive strategies that have been developed in vernacular architecture from different regions are a response to specific climate effects. These strategies are usually simple, low-tech and have low potential environmental impact. For this reason, several studies highlight them as having potential to reduce the demands of non-renewable energy for buildings operation. In this paper, the climatic contrast between northern and southern parts of mainland Portugal is presented, namely the regions of Beira Alta and Alentejo. Additionally, it discusses the contribution of different climate-responsive strategies developed in vernacular architecture from both regions to assure thermal comfort conditions. In Beira Alta, the use of glazed balconies as a strategy to capture solar gains is usual, while in Alentejo the focus is on passive cooling strategies. To understand the effectiveness of these strategies, thermal performances and comfort conditions of two case studies were evaluated based on the adaptive comfort model. Field tests included measurement of hygrothermal parameters and surveys on occupants’ thermal sensation. From the results, it has been found that the case studies have shown a good thermal performance by passive means alone and that the occupants feel comfortable, except during winter where there is the need to use simple heating systems.

    Full Text Available People tend to overestimate emotional responses to future events. This study examined whether such affective forecasting errors occur for feelings of regret, as measured by self-report and subsequent decision-making. Some participants played a pricing game and lost by a narrow or wide margin, while others were asked to imagine losing by such margins. Participants who experienced a narrow loss reported more regret than those who imagined a narrow loss. Furthermore, those experiencing a narrow loss behaved more cautiously in a subsequent gambling task. Thus, the study provides self-report and behavioral evidence for a reversal of the affective forecasting phenomenon for feelings of regret.

    The devices with touchscreen are becoming more popular recently; however, most of them suffer from the crucial drawbacks of lacking accurate tactile feedback. A novel electrocutaneous-based tactile device with the name of E-pad is proposed to provide a dynamic and static low-voltage feedback for touchscreen. We optimize the key parameters of the output voltage and design custom-made hardwares to guarantee a comfortable user experience. Users could move their fingers freely across the touchscreen of the proposed device to really feel virtual objects. Two preliminary experiments are conducted to evaluate the interactive performance of the proposed device and the experimental results show that the proposed device can provide a comfortable and distinct tactile feedback.

    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.

    Full Text Available Outdoor thermal comfort is an essential factor of people’s everyday life and deeply affects the habitability of outdoor spaces. However the indices used for its evaluation were usually developed for indoor environments assuming still air conditions and absence of solar radiation and were only later adapted to outdoor spaces. For this reason, in a previous study the Mediterranean Outdoor Comfort Index (MOCI was developed, which is an empirical index able to estimate the thermal perception of people living in the Mediterranean area. In this study it was compared numerically (by using the data obtained through a field survey with other selected thermal indices. This comparison, performed in terms of Spearman’s rho correlation coefficient, association Gamma, percentage of correct predictions and cross-tabulation analysis, led to identify the MOCI as the most suitable index to examine outdoor thermal comfort in the interested area. As a matter of fact it showed a total percentage of correct predictions of 35.5%. Good performances were reported even in thermophysiological indices as the Physiological Equivalent Temperature (PET and Predicted Mean Vote (PMV. Moreover it was revealed that adaptation and acclimatization phenomena tend to have a certain influence as well.

    Full Text Available While many vehicle control systems focus on vehicle safety and vehicle performance at high speeds, most driving conditions are very low risk situations. In such a driving situation, the ride comfort of the vehicle is the most important performance index of the vehicle. Electro mechanical brake (EMB and other brake-by-wire (BBW systems have been actively researched. As a result, braking actuators in vehicles are more freely controllable, and research on improving ride comfort is also possible. In this study, we develop a control algorithm that dramatically improves ride comfort in low risk braking situations. A method for minimizing the inconvenience of a passenger due to a suddenly changing acceleration at the moment when the vehicle is stopped is presented. For this purpose, an acceleration trajectory is generated that minimizes the discomfort index defined by the change in acceleration, jerk. A controller is also designed to track this trajectory. The algorithm that updates the trajectory is designed considering the error due to the phase lag occurring in the controller and the plant. In order to verify the performance of this controller, simulation verification is completed using a car simulator, Carsim. As a result, it is confirmed that the ride comfort is dramatically improved.

    Phenomenon: Lesbian, gay, bisexual, and transgender (LGBT) individuals face significant barriers in accessing appropriate and comprehensive medical care. Medical students' level of preparedness and comfort caring for LGBT patients is unknown. An online questionnaire (2009-2010) was distributed to students (n = 9,522) at 176 allopathic and osteopathic medical schools in Canada and the United States, followed by focus groups (2010) with students (n = 35) at five medical schools. The objective of this study was to characterize LGBT-related medical curricula, to determine medical students' assessments of their institutions' LGBT-related curricular content, and to evaluate their comfort and preparedness in caring for LGBT patients. Of 9,522 survey respondents, 4,262 from 170 schools were included in the final analysis. Most medical students (2,866/4,262; 67.3%) evaluated their LGBT-related curriculum as "fair" or worse. Students most often felt prepared addressing human immunodeficiency virus (HIV; 3,254/4,147; 78.5%) and non-HIV sexually transmitted infections (2,851/4,136; 68.9%). They felt least prepared discussing sex reassignment surgery (1,061/4,070; 26.1%) and gender transitioning (1,141/4,068; 28.0%). Medical education helped 62.6% (2,669/4,262) of students feel "more prepared" and 46.3% (1,972/4,262) of students feel "more comfortable" to care for LGBT patients. Four focus group sessions with 29 students were transcribed and analyzed. Qualitative analysis suggested students have significant concerns in addressing certain aspects of LGBT health, specifically with transgender patients. Insights: Medical students thought LGBT-specific curricula could be improved, consistent with the findings from a survey of deans of medical education. They felt comfortable, but not fully prepared, to care for LGBT patients. Increasing curricular coverage of LGBT-related topics is indicated with emphasis on exposing students to LGBT patients in clinical settings.

    To explore the crew and passengers' comfort on the Shijiazhuang-Taiyuan passenger dedicated line and physical factors, such as air pressure, noise, wind speed. Comfort investigation of all the crew (n = 244) and passengers (n = 377) on the Shijiazhuang-Taiyuan passenger dedicated line at speed of 250 km/h and 200 km/h and the detection of the air pressure, noise and wind speed were performed in 2011. Significantly higher ratio of comfortable feeling, lower ratio of seriously discomfortable feeling were observed in crew and passengers at 200 km/h compared with those at 250 km/h (P noise in passengers at 200 km/h. No significant difference was observed in ear discomfort induced by air pressure and noise among crew, and the duration of disappearance of discomfortable feeling among passengers between 200 km/h and 250 km/h. The noise in carriages exceeded the related standard when the high-speed train passing through the tunnels. The individuals feel more comfortable at 200 km/h than 250 km/h in this line., which may be related with rapid variation of wind speed and noise when the train passes through the tunnels with high speed.

    In this article, we explore how feelings permeated our qualitative research on suicide. Drawing on phenomenological theory, we argue for the epistemic and ethical importance of the feelings that emerge through research encounters, considering them to be embodied, intersubjective, and multilayered, and requiring careful interpretation through a "reflexivity of feelings." We sketch a tentative framework of the ways that we experienced feelings in our research and give three in-depth examples to illustrate some of the different layers and types of feelings we identified. We reflexively interpret these feelings and their role in our analysis and then discuss some of the ethical and methodological issues related to examining feelings in suicide research, and research more generally. © The Author(s) 2015.

    Three studies explored think ("I think . . . ") versus feel ("I feel . . . ") message framing effects on persuasion.The authors propose a matching hypothesis, suggesting that think framing will be more persuasive when the target attitude or message recipient is cognitively oriented, whereas feel framing will be more persuasive when the target attitude or message recipient is affectively oriented. Study 1 presented cognitively and affectively oriented individuals with a think- or feel-framed message. Study 2 primed cognitive or affective orientation and then presented a think- or feel-framed message. Study 3 presented male and female participants with an advertisement containing think- or feel-framed arguments. Results indicated that think (feel) framing was more persuasive when the target attitude or recipient was cognitively (affectively) oriented. Moreover, Study 2 demonstrated that this matching effect was mediated by processing fluency. Theoretical and practical implications are discussed.

  3. Effect of the Evaporative Cooling on the Human Thermal Comfort and Heat Stress in a Greenhouse under Arid Conditions

    2013-01-01

    Full Text Available Thermal sensation and heat stress were evaluated in a plastic greenhouse, with and without evaporative cooling, under arid climatic conditions in Riyadh, Saudi Arabia. Suitable thermal comfort and heat stress scales were selected for the evaluation. Experiments were conducted in hot sunny days to measure the required parameters (i.e., the dry and wet bulb temperatures, globe temperature, natural wet bulb temperature, and solar radiation flux in the greenhouse. The results showed that in the uncooled greenhouse, workers are exposed to strong heat stress and would feel very hot most of the day time; they are safe from heat stress risk and would feel comfortable during night. An efficient evaporative cooling is necessary during the day to reduce heat stress and to improve the comfort conditions and is not necessary at night. In the cooled greenhouse, workers can do any activity: except at around noon they should follow a proposed working schedule, in which the different types of work were scheduled along the daytimes based on the heat stress value. To avoid heat stress and to provide comfort conditions in the greenhouses, the optimum ranges of relative humidity and air temperature are 48–55% and 24–28°C, respectively.

    Full Text Available Background Considering the advancement of technology and application of various appliances in the workplace, one of the most significant current discussions in the industrial and nonindustrialized workplaces is thermal comfort. Hospital staff have a special status because of the diversity of people employed in hospitals and their crucial roles. Objectives The present study aimed at investigating the staffs’ thermal comfort in a hospital in Esfahan. Methods In this cross-sectional study, Al Zahra hospital staff working in the underground floor were recruited. The sampling method was census, and 161 staff participated in the study. Data were collected by mental assessment using a questionnaire and physical measurement using wet bulb globe temperature (WBGT machine in the summer of 2015. The predicted mean vote (PMV and predicted percentage dissatisfied (PPD were determined based on mental assessment or individual feeling of the staff about thermal comfort. Data management and analyses were performed using SPSS 23. Results The results of the data analysis revealed that kitchen, laundry, and sterilization sectors had higher temperature than other units. Moreover, the results demonstrated that the offices of educational sectors and educational classes had a standard level of thermal comfort according to ASHRAE (American society of heating, refrigerating and air-conditioning engineers Standard 55. The investigations of physical and mental PMV in every unit showed that the total index of these 2 values was 1.2 and 1.39, respectively. Conclusions Based on the results, the units located at the underground floor needed proper design and access to natural ventilation and enough air flow to provide optimum thermal comfort based on international standards.

    Full Text Available The theme of office space is of particular interest because it is a sector strongly involved by technological development. The high concentration of plant engineering systems makes it essential to the attention to environmental parameters and to research on the quality of the relationship which binds man to artificial dimension of built space. In the design of office spaces, the general objective must be to be able to achieve a new working environment relationship. A ratio in which optimal balance is always sought in terms of igrothermal, acoustic and luminous comfort conditions, without noting that the psychological and sociological component plays an important role among the environmental factors, and this significantly interferes with the conditions of physiological comfort.

    Full Text Available Aircraft passengers are more and demanding in terms of thermal comfort. But it is not yet easy for aircraft crew to control the environment control system (ECS that satisfies the thermal comfort for most passengers due to a number of causes. This paper adopts a corrected predicted mean vote (PMV model and an adaptive model to assess the thermal comfort conditions for 31 investigated flights and draws the conclusion that there does exist an uncomfortable thermal phenomenon in civil aircraft cabins, especially in some short-haul continental flights. It is necessary to develop an easy way to predict the thermal sensation of passengers and to direct the crew to control ECS. Due to the assessment consistency of the corrected PMV model and the adaptive model, the adaptive model of thermal neutrality temperature can be used as a method to predict the cabin optimal operative temperature. Because only the mean outdoor effective temperature ET∗ of a departure city is an input variable for the adaptive model, this method can be easily understood and implemented by the crew and can satisfy 80–90% of the thermal acceptability levels of passengers.

    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.

    Efforts are made to grasp the parts remaining technically unsolved of the ozone-aided technology for creating a comfortable environment, such as ozone-aided enhancement of the decomposition of nondegradable organic matters in the urban sewage and industrial wastewater. Efforts are also made to put in order and analyze data about the said technology, to isolate the current problems and the objects of technical deliberation for the future, and to examine the feasibility of the introduction of this technology. Case studies were conducted for a novel ozone-aided system and the effect is examined of the introduction of ozone-aided treatment into crowded towns, water supply systems, sewerage, and industries that handle paper and pulp, chemicals, electric power, and foods. Findings are mentioned below. The ozone utilizing technology when introduced improves the efficiency of water circulation, reduces pollutants at an excellent rate, suppresses the generation of carbon dioxide, and enhances safety of water resources and water environments. To realize such good results, however, it is important for the ozone to be high in concentration, for the accelerated oxidation and enhanced biofunction processes to be further studied, and for the system to be optimized. It is also found that a technology of appropriate ozone storage will help enhance cost reduction. (NEDO)

    Full Text Available The aim of the study was to examine the relation between lower limb comfort scores and injury and to measure the responsiveness of a lower limb comfort index (LLCI to changes over time, in a cohort of professional footballers. Lower limb comfort was recorded for each individual using a comfort index which assessed the comfort status of five anatomical segments and footwear. Specifically we tested the extent to which comfort zones as measured by the LLCI were related to injury measured as time loss events. The hypothesis for the study was that poor lower limb comfort is related to time loss events (training or match day. A total of 3524 player weeks of data was collected from 182 professional athletes encompassing three codes of football (Australian Rules, Rugby league, Rugby Union. The study was conducted during football competition periods for the respective football leagues and included a period of pre- season training. The results of regression indicated that poor lower limb comfort was highly correlated to injury (R2 =0.77 and accounted for 43.5 time loss events/ 1000hrs football exposure. While poor comfort was predictive of injury 47% of all time loss events it was not statistically relevant (R2 =0.18. The results indicate lower limb comfort can be used to assess the well-being of the lower limb; poor comfort is associated with injury, and the LLCI has good face validity and high criterion-related validity for the relationship between comfort and injury

  15. 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.

    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. PMID:24311976

    This mixed-methods exploratory study identified and then developed and validated a quantitative measure of a new construct of mental suffering in the occupied Palestinian territory: feeling broken or destroyed. Group interviews were conducted in 2011 with 68 Palestinians, most aged 30-40, in the West Bank, East Jerusalem, and the Gaza Strip to discern local definitions of functioning. Interview participants articulated of a type of suffering not captured in existing mental health instruments used in regions of political conflict. In contrast to the specific difficulties measured by depression and PTSD (sleep, appetite, energy, flashbacks, avoidance, etc.), participants elaborated a more existential form of mental suffering: feeling that one's spirit, morale and/or future was broken or destroyed, and emotional and psychological exhaustion. Participants articulated these feelings when describing the rigors of the political and economic contexts in which they live. We wrote survey items to capture these sentiments and administered these items-along with standard survey measures of mental health-to a representative sample of 1,778 32-43 year olds in the occupied Palestinian territory. The same survey questions also were administered to a representative subsample (n = 508) six months earlier, providing repeated measures of the construct. Across samples and time, the feeling broken or destroyed scale: 1) comprised a separate factor in exploratory factor analyses, 2) had high inter-item consistency, 3) was reported by both genders and in all regions, 4) showed discriminate validity via moderate correlations with measures of feelings of depression and trauma-related stress, and 5) was more commonly experienced than either feelings of depression or trauma-related stress. Feeling broken or destroyed can be reliably measured and distinguished from conventional measures of mental health. Such locally grounded and contextualized measures should be identified and included in

    Although exercise-induced feeling states may play a role in driving future behavior, their role in relation to older adults' participation in physical activity (PA) has seldom been considered. The objectives of this study were to describe changes in older adults' feeling states during exercise, and examine if levels of and changes in feeling states predicted their future participation in PA. Self-reported data on feeling states were collected from 82 older adults immediately before, during, and after a moderate-intensity exercise session, and on participation in PA 1 month later. Data were analyzed using latent growth modeling. Feelings of revitalization, positive engagement, and tranquility decreased during exercise, whereas feelings of physical exhaustion increased. Feelings of revitalization immediately before the exercise session predicted future participation in PA; changes in feeling states did not. This study does not provide empirical evidence that older adults' exercise-induced feeling states predict their future participation in PA.

    This report highlights findings from the Study of Psychiatrists' Use of Informational Resources in Clinical Practice, a cross-sectional Web- and paper-based survey that examined psychiatrists' comfort using computers and other electronic devices in clinical practice. One-thousand psychiatrists were randomly selected from the American Medical Association Physician Masterfile and asked to complete the survey between May and August, 2012. A total of 152 eligible psychiatrists completed the questionnaire (response rate 22.2 %). The majority of psychiatrists reported comfort using computers for educational and personal purposes. However, 26 % of psychiatrists reported not using or not being comfortable using computers for clinical functions. Psychiatrists under age 50 were more likely to report comfort using computers for all purposes than their older counterparts. Clinical tasks for which computers were reportedly used comfortably, specifically by psychiatrists younger than 50, included documenting clinical encounters, prescribing, ordering laboratory tests, accessing read-only patient information (e.g., test results), conducting internet searches for general clinical information, accessing online patient educational materials, and communicating with patients or other clinicians. Psychiatrists generally reported comfort using computers for personal and educational purposes. However, use of computers in clinical care was less common, particularly among psychiatrists 50 and older. Information and educational resources need to be available in a variety of accessible, user-friendly, computer and non-computer-based formats, to support use across all ages. Moreover, ongoing training and technical assistance with use of electronic and mobile device technologies in clinical practice is needed. Research on barriers to clinical use of computers is warranted.

Psychiatrists generally reported comfort using computers for personal and educational purposes. However, use of computers in clinical care was less common, particularly among psychiatrists 50 and older. Information and educational resources need to be available in a variety of accessible, user-friendly, computer and non-computer-based formats, to support use across all ages. Moreover, ongoing training and technical assistance with use of electronic and mobile device technologies in clinical practice is needed. Research on barriers to clinical use of computers is warranted. PMID:26667248

  2. The human thermoneutral and thermal comfort zones: Thermal comfort in your own skin blood flow.

    Human thermoregulation is achieved via autonomic and behavioral responses. Autonomic responses involve 2 synchronous 'components'. One counteracts large thermal perturbations, eliciting robust heat loss or gain (i.e., sweating or shivering). The other fends off smaller insults, relying solely on changes in sensible heat exchange (i.e., skin blood flow). This sensible component occurs within the thermoneutral zone [i.e., the ambient temperature range in which temperature regulation is achieved only by sensible heat transfer, without regulatory increases in metabolic heat production (e.g., shivering) or evaporative heat loss (e.g., sweating)].(1) The combination of behavior and sensible heat exchange permits a range of conditions that are deemed thermally comfortable, which is defined as the thermal comfort zone.(1) Notably, we spend the majority of our lives within the thermoneutral and thermal comfort zones. It is only when we are unable to stay within these zones that deleterious health and safety outcomes can occur (i.e., hypo- or hyperthermia). Oddly, although the thermoneutral zone and thermal preference (a concept similar to the thermal comfort zone) has been extensively studied in non-human animals, our understanding of human thermoregulation within the thermoneutral and thermal comfort zones remains rather crude.

    In this paper, thermal comfort issues of the operators working on one of the electronics companies in the evaporator area are observed. The objective of this study is to reduce Percentage of Dissatisfied (PD) of operators in an effort to improve the work productivity. PD is predicted using CBE Thermal Comfort Tool by measuring the thermal variables around the evaporator area and by calculating the Heat Stress Index (HSI). The operator productivity is analyzed by Wet Bulb Globe Thermometer (WBGT) Work-Rest Chart. The PD of operators before and after improvement is compared. The results showed that the average temperature around the operators area at evaporator station is high with average WBGT of 33,6°C. HSI value is 51.95 indicating that the effect of 8-h exposure is severe strain with work impact is health threat for unit operators and acclimatization is necessary. The PD value is 96% indicating that almost all operators feel uncomfortable at work. These indicate that the thermal environment should be improved. The proposed improvement is by installing water cooled and sprayed into the evaporator area. This installation is able to reduce HSI and PD by more 70% and more 60%, respectively. These findings indicate that improving the thermal environment will be able to improve working comfort which will further affect the level of work productivity.

    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.

    Energy use in offices buildings is largely driven by air conditioning demands. But the optimal temperature is not the same for all building occupants, leading to the infamous thermostat war. And many occupants have independently overcome building comfort weaknesses with their own space heaters or fans. NREL tested is a customized office chair that automatically heats and cools the occupant along the seat and chair back according to the occupants' personal preferences. This product is shown to deliver markedly better comfort at room temperatures well above typical office cooling setpoints. Experimental subjects reported satisfaction in these elevated air temperatures, partly because the chair's cooling effect was tuned to their own individual needs. Simulation of the chair in office buildings around the U.S. shows that energy can be saved everywhere, with impacts varying due to the climate. Total building HVAC energy savings exceeded 10% in hot-dry climate zones. Due to high product cost, simple payback for the chair we studied is beyond the expected chair life. We then understood the need to establish cost-performance targets for comfort delivery packages. NREL derived several hypothetical energy/cost/comfort targets for personal comfort product systems. In some climate regions around the U.S., these show the potential for office building HVAC energy savings in excess of 20%. This report documents this research, providing an overview of the research team's methods and results while also identifying areas for future research building upon the findings.

    People say they enjoy both seeing a preferred social group succeed and seeing an adversary social group fail. At the same time, they state they dislike seeing a preferred social group fail and seeing an adversary social group succeed. The current magnetic resonance imaging study investigated whether-and if so, how-such similarities in reported feeling states are reflected in neural activities. American football fans anticipated success and failure situations for their favorite or their adversary teams. The data support the idea that feeling similarities and divergences expressed in verbal reports carry with them significant neural similarities and differences, respectively. Desired (favorite team likely to win and adversary team likely to lose) rather than undesired (favorite team likely to lose and adversary team likely to win) outcomes were associated with heightened activity in the supramarginal gyrus, posterior cingulate cortex, insula, and cerebellum. Precuneus activity additionally distinguished anticipated desirable outcomes for favorite versus adversary teams. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available The present article is an analysis of the role of akratic feelings on empathy and self-consciousness. It argues that akratic feelings create a meta-emotional platform that allows the installation of a type of empathic process, which simultaneously contributes for self-consciousness. The article shows in what way akratic feelings are crucial to further understand both ourselves and others.The article begins by describing the nature of akratic feelings and the way in which we can find them at various emotional levels. The second part points out how akratic feelings contribute to empathetic processes and their role in the formation of a meta-emotional platform in which people recognize their opacity. Finally, the article points out how this also contributes for self-awareness, and ultimately for a better understanding of emotional processes.

    Environmental conditions such as lighting and thermal comfort are influencing factors on sleep quality and visual tiredness. The purpose of this study was the determination of the relationship between thermal comfort and light intensity with the sleep quality and eye fatigue in shift nurses. This cross-sectional research was conducted on 82 shift-work personnel of 18 nursing workstations in Isfahan Al-Zahra Hospital, Iran, in 2012. Heat stress monitoring (WBGT) and photometer (Hagner Model) were used for measuring the thermal conditions and illumination intensity, respectively. To measure the sleep quality, visual tiredness, and thermal comfort, Pittsburg sleep quality index, eye fatigue questionnaire, and thermal comfort questionnaire were used, respectively. The data were analyzed with descriptive statistics, Student's t-test, and Pearson correlation. Correlation between thermal comfort which was perceived from the self-reporting of people with eye tiredness was -0.38 (P = 0.002). Pearson correlation between thermal comfort and sleep quality showed a positive and direct relationship (r = 0.241, P = 0.33) but the correlation between thermal comfort, which was perceived from the self-reporting of shift nurses, and WBGT index was a weak relationship (r = 0.019). Based on the obtained findings, it can be concluded that a defect in environmental conditions such as thermal conditions and light intensity and also lack of appropriate managerial plan for night shift-work nurses are destructive and negative factors for the physical and mental health of this group of practitioners.

    Emerging evidence indicates that critically ill children are particularly at risk for incurring significant psychological harm. Little is known about these children's actual experiences. The aim of the study was to examine children's experience of critical illness. The research question was: What are a critically ill child's sources of discomfort and comfort? Interpretive phenomenology was selected as the study's method. Children's accounts were examined to identify what they considered meaningful, in terms of their experienced discomfort and comfort. Data sources included formal and informal interviews with child-participants, drawings provided by some participants, and field-notes documenting observed non-verbal data. Twelve children were enrolled in the study, ranging from 3 to 17years of age; including four girls and eight boys. Although all participants were able to discuss the discomfort and comfort they experienced, they reported difficulties in remembering part or most of their experience. Some participants characterized their Pediatric Intensive Care Unit stay quite favourably or as "not that bad", while some described their experience unfavourably. Diverse types of discomforts were reported, including fears and worries, hurt and pain, invasive interventions, missing significant people, noise, food or eating problems, boredom, physical symptoms, as well as four additional discomforts reported by individual participants. Several sources of comfort were described, including parents, visitors and friends, hospital staff (principally nurses), stuffed animal/favourite blanket, entertainment and play, food, selected medical interventions, thinking of going home, being able to walk or run, sleep, waking up, gifts, along with two other comforts reported by individual participants. Embodiment and a tension between aloneness and being with were identified as the principal phenomena underlying these children's experiences. The findings complement existing knowledge

    Advantages of the type of electric floor heating installed in an exclusive condominium development in Whistler, a winter sports resort community in British Columbia, are discussed. Quality, comfort, strict limits on the amount of available electricity, and reduced maintenance, were the principal reasons for installing this type of heating system, according to the designer of the complex. Floor heating, being a radiant heating system, eliminates wasteful stratification of heat in a given heated space, thus helping to achieve comfortable ambient temperature at a lower level than would be required with conventional heating systems, reducing the power requirements by as much as 25 per cent. The system maintains a uniform temperature without any movement of air, dust and germs, providing occupants with a clean and pleasant atmosphere. The Flexterm system can be used under a variety of floor coverings -- natural stone, ceramic, marble, carpets, vinyl tiles, or wood flooring. It can be used selectively in different rooms of a housing unit, while other parts (in this instance the bedrooms), are heated by small electric baseboard heaters.

    Since the birth of aviation medicine approximately 80 yrs ago, practitioners and scientists have given their attention primarily to flight deck crew, cabin crew, and ground support personnel. However, in more recent years we have broadened our horizons to include the safety, health, and comfort of passengers flying commercial aircraft. This will be even more compelling as more passengers take to the air in larger aircraft and flying longer hours to more distant destinations. Further, we can expect to see more older passengers because people in many countries are living longer, healthier lives. The author first discusses the stresses imposed by ordinary commercial flight upon travelers such as airport tumult, barometric pressure changes, immobility, jet lag, noise/ vibration, and radiation. Medical considerations are next addressed describing inflight illness and medical care capability aboard U.S. air carriers. Passenger safety, cabin air quality, and the preventive medicine aspects of air travel are next reviewed in the context of passenger safety, health, and comfort. Recommendations are addressed to regulator agencies, airlines aircraft manufacturers, and the aerospace medicine community.

  18. Thermodynamical analysis of human thermal comfort

    Traditional methods of human thermal comfort analysis are based on the first law of thermodynamics. These methods use an energy balance of the human body to determine heat transfer between the body and its environment. By contrast, the second law of thermodynamics introduces the useful concept of exergy. It enables the determination of the exergy consumption within the human body dependent on human and environmental factors. Human body exergy consumption varies with the combination of environmental (room) conditions. This process is related to human thermal comfort in connection with temperature, heat, and mass transfer. In this paper a thermodynamic analysis of human heat and mass transfer based on the 2nd law of thermodynamics in presented. It is shown that the human body's exergy consumption in relation to selected human parameters exhibits a minimal value at certain combinations of environmental parameters. The expected thermal sensation also shows that there is a correlation between exergy consumption and thermal sensation. Thus, our analysis represents an improvement in human thermal modelling and gives more information about the environmental impact on expected human thermal sensation

    The largest market segment of global tourism is coastal tourism, which is strongly dependent on the destination's thermal climate. To date, outdoor bioclimatic comfort assessments have focused exclusively on local residents in open urban areas, making it unclear whether outdoor comfort is perceived differently in non-urban environments or by non-residents (i.e. tourists) with different weather expectations and activity patterns. This study provides needed insight into the perception of outdoor microclimatic conditions in a coastal environment while simultaneously identifying important psychological factors that differentiate tourists from everyday users of urban spaces. Concurrent micrometeorological measurements were taken on several Caribbean beaches in the islands of Barbados, Saint Lucia and Tobago, while a questionnaire survey was used to examine the thermal comfort of subjects ( n = 472). Universal Thermal Climate Index (UTCI) conditions of 32 to 39 °C were recorded, which were perceived as being "slightly warm" or "warm" by respondents. Most beach users (48 to 77 %) would not change the thermal conditions, with some (4 to 15 %) preferring even warmer conditions. Even at UTCI of 39 °C, 62 % of respondents voted for no change to current thermal conditions, with an additional 10 % stating that they would like to feel even warmer. These results indicate that beach users' thermal preferences are up to 18 °C warmer than the preferred thermal conditions identified in existing outdoor bioclimatic studies from urban park settings. This indicates that beach users hold fundamentally different comfort perceptions and preferences compared to people using urban spaces. Statistically significant differences ( p ≤ .05) were also recorded for demographic groups (gender, age) and place of origin (climatic region).

    A study with calculation software Vabi 114 shows that choosing a different climate year and comfort level requirements according to the Dutch standard NEN 5060 can lead to an increased cooling capacity of over 60%. When determining the climate year and comfort level in the program of requirements, it will have to be weighed if the increasing cost at the expense of the additional cooling capacity outweighs the increased level in comfort. [Dutch] Het is de laatste jaren een trend om andere klimaatjaren of andere comforteisen te hanteren. Het oude klimaatjaar1964-1965 wordt steeds vaker vervangen door jaren zoals 1995,1998 of nieuwe klimaatreferentiejaren conform de NEN 5060:2008. Ook de comforteisen veranderen. De eis van 150 gewogen overschrijdingsuren die de Rijksgebouwendienst jarenlang hanteerde, wordt steeds vaker vervangen door een eis met een maximale binnentemperatuur van 25C of adaptieve temperatuurgrenswaarden (ATG), zoals omschreven in ISSO-publicatie 74.

    This study aims to determine whether patients with rheumatoid arthritis (RA) experience more general feelings of guilt and shame than their peers without RA and to examine possible correlates of guilt and shame in RA. In a cross-sectional survey study, 85 out-patients with RA (77 % female; median disease duration, 11 years) and 59 peer controls completed the Experience of Shame Scale (ESS) and the Test of Self-Conscious Affect (TOSCA). Patients additionally completed measures of health status, self-efficacy, cognitive emotion regulation, and numerical rating scales for life satisfaction and happiness. Patients and peer controls were well matched for sociodemographic characteristics. No significant differences between patients and controls were found for guilt or different types of shame as measured with the TOSCA or ESS. In multivariate analyses, female patients reported more feelings of bodily shame and higher guilt proneness, while younger patients reported more character and bodily shame. Worse social functioning and more self-blaming coping strategies were the strongest independent correlates of shame. Shame proneness was only independently associated with more self-blame, whereas guilt proneness was only associated with female sex. None of the physical aspects of the disease, including pain and physical functioning, correlated with feelings of guilt and shame. Patients with longstanding RA do not experience more general feelings of shame or guilt than their peers without RA. Shame and guilt in RA is primarily associated with demographic and psychosocial characteristics and not with physical severity of the disease.

    The objective of this study was to explore passengers' comfort experience of extra seat belts during on-road driving in the rear seat of a passenger car and to investigate how the use of extra belts affects children's and adults' attitudes to the product. Two different seat belt systems were tested, criss-cross (CC) and backpack (BP), consisting of the standard 3-point belt together with an additional 2-point belt. In total, 32 participants (15 children aged 6-10, 6 youths aged 11-15, and 11 adults aged 20-79, who differed considerably in size, shape, and proportions) traveled for one hour with each system, including city traffic and highway driving. Four video cameras monitored the test subject during the drive. Subjective data regarding emotions and perceived discomfort were collected in questionnaires every 20 min. A semistructured interview was held afterwards. All participant groups accepted the new products and especially the increased feeling of safety (P car. CC was appreciated for its symmetry, comfort, and the perceived feeling of safety. Some participants found CC unpleasant because the belts tended to slip close to the neck, described as a strangling feeling. BP was simpler to use and did not cause annoyance to the neck in the way CC did. Instead, it felt asymmetric and to some extent less safe than CC. Body size and shape affected seat belt fit to a great extent, which in turn affected the experience of comfort, both initially and over time. Perceived safety benefit and experienced comfort were the most determinant factors for the attitude toward the extra seat belts. The extra seat belts were perceived as being better than the participants had expected before the test, and they became more used to them over time. This exploratory study provided valuable knowledge from a user perspective for further development of new seat belt systems in cars. In addition to an increased feeling of safety, seat belt fit and comfort are supplementary influencing

    Full Text Available This study aims to determine the optimal approach for evaluating thermal comfort in an office that uses natural ventilation as the main conditioning strategy; the office is located in Quito-Ecuador. The performance of the adaptive model included in CEN Standard EN15251 and the traditional PMV model are compared with reports of thermal environment satisfaction surveys presented simultaneously to all occupants of the office to determine which of the two comfort models is most suitable to evaluate the thermal environment. The results indicate that office occupants have developed some degree of adaptation to the climatic conditions of the city where the office is located (which only demands heating operation, and tend to accept and even prefer lower operative temperatures than those considered optimum by applying the PMV model. This is an indication that occupants of naturally conditioned buildings are usually able to match their comfort temperature to their normal environment. Therefore, the application of the adaptive model included in CEN Standard EN15251 seems like the optimal approach for evaluating thermal comfort in naturally conditioned buildings, because it takes into consideration the adaptive principle that indicates that if a change occurs such as to produce discomfort, people tend to react in ways which restore their comfort.

    "9IBACOS monitored 37 homes during the late summer and early fall of 2014 in a hot and humid climate to better understand indoor comfort conditions. These homes were constructed in the last several years by four home builders that offered a comfort and performance guarantee for the homes. The homes were located in one of four cities: Tampa, Florida; Orlando, Florida; Houston, Texas; and San Antonio, Texas. Temperature and humidity data were collected from the thermostat and each room of the house using small, battery-powered data loggers. To understand system runtime and its impact on comfort, supply air temperature also was measured on a 1-minute interval. Overall, the group of homes only exceeded a room-to-room temperature difference of 6 degrees F for 5% of the time. For 80% of the time, the rooms in each house were within 4 degrees F of each other. Additionally, the impact of system runtime on comfort is discussed. Finally, measurements made at the thermostat were used to better understand the occupant operation of each cooling system's thermostat setpoint. Builders were questioned on their perceived impact of offering a comfort and performance guarantee. Their feedback, which generally indicates a positive perception, has been summarized in the report.

    How manageable a person feels the place exceedingly influences people’s satisfaction toward supporting tourism development with the respect of self-efficacy. Individuals with self-efficacious can perform or complete a task as a measure of personal agency. This research aims to investigate the influences of self-efficacy principle in defining place identity on tourism environment in Karo Regency, North Sumatera, Indonesia. A mixed-method was employed to obtain local people’ and tourists’ perception of comfort, safety, accessibility, and confidence. The result shows that confidence contributes in maintaining self-efficacy in Karo Regency. Meanwhile, the absence of public facilities constitutes the feeling of self-efficacy and threatens the place identity.

    YOUR Blessed Health (YBH) is a faith-based HIV prevention pilot program designed to increase faith-based organizations' capacity to address HIV/AIDS among African American congregations. Faith leaders (e.g., pastors, pastors' spouses) were trained to deliver youth and adult HIV education sessions. Perceptions of comfort with discussing 11 sexual health topics were assessed after program implementation. Twenty-nine faith leaders self-reported their comfort discussing sexual behaviors, sexual communication, and sexual abuse. Overall, faith leaders were comfortable discussing these sexual health topics; however, denominational and leadership role differences were found. These findings suggest African American faith leaders are willing to lead faith-based HIV prevention efforts, but that consideration of denominational differences and organizational roles in faith-based health promotion programs is critical.

  13. Urban Climate Design: Improving thermal comfort in Dutch neighbourhoods

    Directory of Open Access Journals (Sweden)

    Laura Kleerekoper

    2017-11-01

    Full Text Available This thesis presents research into the possibilities for climate adaptation in Dutch urban areas. We want to know how cities can best prepare for extreme rainfall, droughts, and heat waves in future climates. These events are likely to become more frequent and more extreme. The focus is on heat resistance as this has been a neglected concept in Dutch urban planning. The aim of this study is to extend our knowledge of the effects of climate-adaptation measures and to stimulate the implementation of such measures in the design of public space. Anticipating on the effects of climate change, the research was guided by the question: Which urban design principles can be applied in specific Dutch neighbourhoods to respond to the effects of climate change, especially in terms of outdoor thermal comfort and water management? The three stages of the project are:  • A literature review of existing knowledge on climate adaptation and knowledge gaps • Research into the specific field of urban climatology • Applied research on the broader field of urban planning The urban climate and adaptation measures In the evaluation of measures for climate robust urban areas it is important to gauge the extent of the effects of such measures. These effects are generally expressed in terms of air temperature. However, the comparison of results of measures from various studies is not a simple matter: there are significant differences in spatial, climatological and methodological variations adopted in these studies. Bringing results together from very specific studies may give an impression of the potential of certain measures. For example, most studies support the idea that greening has the highest effect on thermal comfort as it provides both shade and active cooling due to ‘evapotranspiration’1. Nevertheless, vegetation can also retain heat, as we can feel after sundown. Other measures that were investigated for their effects are water, urban morphology

    Izaute, Marie; Chambres, Patrick; Larochelle, Serge

    2002-12-01

    The main objective of the presented study was to study feeling-of-knowing (FOK) in proper name retrieval. Many studies show that FOK can predict performance on a subsequent criterion test. Although feeling-of-knowing studies involve questions about proper names, none make this distinction between proper names and common names. Nevertheless, the specific character of proper names as a unique label referring to a person should allow participants to target precisely the desired verbal label. Our idea here was that the unique character of proper name information should result in more accurate FOK evaluations. In the experiment, participants evaluated feeling-of-knowing for proper and common name descriptions. The study demonstrates that FOK judgments are more accurate for proper names than for common names. The implications of the findings for proper names are briefly discussed in terms of feeling-of-knowing hypotheses.

  18. Emotion in Schizophrenia: Where Feeling Meets Thinking.

    Science.gov (United States)

    Kring, Ann M; Caponigro, Janelle M

    2010-08-01

    Our understanding of the nature of emotional difficulties in schizophrenia has been greatly enhanced by translational research over the past two decades. By incorporating methods and theories from affective science, researchers have been able to discover that people with schizophrenia exhibit very few outward displays of emotion but report experiencing strong feelings in the presence of emotionally evocative stimuli or events. Recent behavioral, psychophysiological, and brain imaging research has pointed to the importance of considering the time course of emotion in schizophrenia. This work has shown that people with schizophrenia have the ability to experience emotion in the moment; however, they appear to have difficulties when anticipating future pleasurable experiences, and this perhaps affects their motivation to have such experiences. While advancements in our understanding of emotional experience and expression in individuals with schizophrenia have been made, these developments have led to a new collection of research questions directed at understanding the time course of emotion in schizophrenia, including the role of memory and anticipation in motivated behavior, translating laboratory findings to the development of new assessment tools and new treatments targeting emotional impairments in people with this disorder.

    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.

    these goals include phasing out all use of electricity for space heating and for hot water supply. Furthermore building codes should require new buildings to be very well insulated, 30-40 cm mineral wool, for instance, and low energy windows. Similar codes, although not always as strict, should be applied......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.

    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.

  7. Task difficulty, risk, effort and comfort in a simulated driving task--Implications for Risk Allostasis Theory.

    Science.gov (United States)

    Lewis-Evans, Ben; Rothengatter, Talib

    2009-09-01

    Risk Allostasis Theory states that drivers seek to maintain a feeling of risk within a preferred range [Fuller, R., 2008. What drives the driver? Surface tensions and hidden consensus. In: Keynote at the 4th International Conference on Traffic and Transport Psychology, Washington, DC, August 31-September 4, 2008]. Risk Allostasis Theory is the latest version of Task-Difficulty Homeostasis theory, and is in part based on the findings of experiments where participants were asked to rate the task difficulty, feeling of risk and chance of collision of scenes shown in digitally altered video clips [Fuller, R., McHugh, C., Pender, S., 2008b. Task difficulty and risk in the determination of driver behaviour. Revue européenne de psychologie appliqée 58, 13-21]. The focus of the current research was to expand upon the previous video based experiments using a driving simulator. This allowed participants to be in control of the vehicle rather than acting as passive observers, as well as providing additional speed cues. The results support previous findings that ratings of task difficulty and feeling of risk are related, and that they are also highly related to ratings of effort and moderately related to ratings of comfort and habit. However, the linearly increasing trend for task difficulty and feeling of risk described by the previous research was not observed: instead the findings of this experiment support a threshold effect where ratings of risk (feeling of and chance of loss of control/collision), difficulty, effort, and comfort go through a period of stability and only start to increase once a certain threshold has been crossed. It is within the period of stability where subjective experience of risk and difficulty is low, or absent, that drivers generally prefer to operate.

  8. When feeling bad leads to feeling good: guilt-proneness and affective organizational commitment.

    Science.gov (United States)

    Flynn, Francis J; Schaumberg, Rebecca L

    2012-01-01

    The authors posit that higher levels of guilt-proneness are associated with higher levels of affective organizational commitment. To explain this counterintuitive link, the authors suggest that a dispositional tendency to feel guilt motivates individuals to exert greater effort on their work-related tasks that, in turn, strengthens their affinity for the organization. The authors tested this idea using a laboratory study and field data from 2 samples of working adults. Individuals who are more guilt-prone reported higher levels of organizational attachment compared with less guilt-prone individuals. Furthermore, mediation analyses indicate that the link between guilt-proneness and affective commitment is driven by greater task effort. The authors discuss the implications of these findings for understanding the affective drivers of commitment in organizations.

    Full Text Available Decades ago, the only requirement to construct a building was to give men the right conditions for the execution of their work or leisure activities. With the development of knowledge about the internal and external environments of buildings, other requirements have been added such as the issue of user comfort. New construction techniques have been incorporated and new products have been created to improve internal environment comfort. This research addressed the importance of using indicators related to environmental comfort in sustainability assessment tools applied to school buildings. It also considered the importance of environmental issues for the good performance of human beings, and the harmonious coexistence of the comfort indicators indoor air quality, thermal comfort, visual comfort, acoustic comfort and ergonomic comfort based on data gathered in research carried out with users of high schools (only students. This research was carried out in two different cities of different countries, Guimarães (Portugal and Juiz de Fora (Brazil, that have similar characteristics of teaching standards and climate conditions (temperature and air humidity. In this study, interviews were made through questionnaires and, later, the information collected was analyzed. This study demonstrates the need to include an ergonomic indicator for school buildings in sustainability assessment tools.

    Water-based activities may result in the loss of thermal comfort (TC). We hypothesized that in cooling water, the hands and feet would be responsible. Supine immersions were conducted in up to five clothing conditions (exposing various regions), as well as investigations to determine if a "reference" skin temperature (Tsk) distribution in thermoneutral air would help interpret our findings. After 10 min in 34.5 °C water, the temperature was decreased to 19.5 °C over 20 min; eight resting or exercising volunteers reported when they no longer felt comfortable and which region was responsible. TC, rectal temperature, and Tsk were measured. Rather than the extremities, the lower back and chest caused the loss of overall TC. At this point, mean (SD) chest Tsk was 3.3 (1.7) °C lower than the reference temperature (P = 0.005), and 3.8 (1.5) °C lower for the back (P = 0.002). Finger Tsk was 3.1 (2.7) °C higher than the reference temperature (P = 0.037). In cool and cooling water, hands and feet, already adapted to colder air temperatures, will not cause discomfort. Contrarily, more discomfort may arise from the chest and lower back, as these regions cool by more than normal. Thus, Tsk distribution in thermoneutral air may help understand variations in TC responses across the body. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    I was weak in predicting what the challenges of learning could be for my students. I decided to become more engaged in research investigating reasons for not learning than just doing teaching as a job. A graduate study experience in teaching mathematics or any close research discipline related to teaching and learning could be more helpful for me to find answers to my questions. My writing experience as an extracurricular activity was totally helpful for me to find my research interests. As I pondered while writing, I discovered that my personal characteristics, such as being sensitive to others, were directing me to psychology of education. Interestingly, I was feeling better when I wrote about my students’ emotional approach to mathematics. It gave me an opportunity to make a comparison between my emotions about specific course subjects and my students’. Obviously it was not a good thing to expect everyone to love mathematics, but there could be a way to help them like it as much as possible. An observation that I noted down in 2014 in my diary is as follows: “It is the seventh week and 1 Independent Researcher - Gainesville, Florida, USA - seydauysal5@gmail.com UYSAL Letter to the Editor: How I Left My Comfort Zone in Pure Mathematics 170 some of my students insist on having prejudice against mathematics, which is a challenge in my job.

This is what teaching is all about, isn’t it?” After reading a number of books and articles, I was closer to being sure about my research interest. Furthermore, writing regularly about what I have gradually learnt helped me more. How could I make people love mathematics? I have been looking for ways of achieving this actual target.

    The symptoms of an illness that requires chemotherapy and the corresponding effects of such treatment exacerbate the pain and discomfort that patients typically experience. Listening to music may help patients cope with chemotherapy symptoms, thereby contributing to their physical ease and well-being. Seventy patients who were receiving treatment at the outpatient chemotherapy unit were invited to participate in this work. During chemotherapy sessions and the week after the sessions, the patients listened to music with headphones. The occurrence of chemotherapy symptoms such as pain, tiredness, nausea, depression, anxiety, drowsiness, lack of appetite, not feeling well, and shortness of breath in the intervention group was statistically significant after listening to music ( p listening to music effectively reduces the severity of chemotherapy symptoms and enhances the comfort of patients receiving the treatment.

Solutions that respond to the impact of human activities on the environment in urban areas are required. On one hand, averting resource depletion and environmental degradation caused by facilities and infrastructures over their life cycle is a principal goal. On the other hand, it is also a principal goal to create livable, comfortable, safe and productive built environments. Tabriz bazaar, in Iran, is an example of sustainable architecture. It is designed to be suited to the local climate and urban texture with spaces that are varied and have a strong connection to open space. The bazaar plays a significant role in creation of safe urban space as a cultural, social, commercial, educational and sanitarian area. It connects different activities and different people in a safe place. The purpose of this paper is to determine the sustainability of the Tabriz bazaar and the effect that the character of this commercial area has on the quality of human life.

  1. THE "COMFORT WOMEN" OF THE PACIFIC WAR

    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.

  2. Feels Right … Go Ahead? When to Trust Your Feelings in Judgments and Decisions

    Full Text Available Not only are subjective feelings an integral part of many judgments and decisions, they can even lead to improved decisions and better predictions. Individuals who have learned to trust their feelings performed better in economic-negotiation games than their rational-thinking opponents. But emotions are not just relevant in negotiations and decisions. They also play a decisive role in forecasting future events. Candidates who trusted their feelings made better predictions than people with less emotional confidence. Emotions contain valuable information about the world around us. This information is not as readily available in our mind as hard facts but rather lies in the background of our conscious attention. In negotiation situations like the ultimatum game, feelings provide an intuitive sense of what offer is about right and what offer is too high or too low. But feelings also summarize statistical relationships among things that, on the surface, may seem disconnected. These statistical relationships make more probable futures feel more right than less probable futures. However, researchers warn that you should not always trust your feelings. Feelings that tend to help are those based on general knowledge, not those based on easy-to-verbalize local knowledge.

    1997-03-01

    Individuals who are unqualified to fulfill a role are impostors. Often, competent practitioners feel they are unable to successfully practice their profession and suffer from an impostor syndrome. In health care, this can have a number of negative outcomes, including a poor reflection of the institution through the individual's actions. In many cases, impostorship can be prevented or remediated through the use of techniques such as identification, mentoring, and promotion of positive self-concepts. This article reviews a number of these techniques to help supervisors, especially new supervisors who may have feelings of inadequacy and impostorship, in developing a positive self-image.

    Work related musculoskeletal disorders (WMSD) are a serious risk to workers' health in any work environment, and especially in clinical work places. These disorders are typically the result of prolonged exposure to non-ergonomic postures and the resulting discomfort in the workplace. Thus a continuous assessment of comfort and ergonomics is necessary. There are different techniques available to make such assessments, such as self-reports on perceived discomfort and observational scoring models based on the posture's relevant joint angles. These methods are popular in medical and industrial environments alike. However, there are uncertainties with regards to objectivity of these methods and whether they provide a full picture. This paper reports on a study about these methods and how they correlate with the activity of muscles involved in the task at hand. A wearable 4-channel electromyography (EMG) and joint angle estimation device with wireless transmission was made specifically for this study to allow continuous, long-term and real-time measurements and recording of activities. N=10 participants took part in an experiment involving a buzz-wire test at 3 different levels, with their muscle activity (EMG), joint angle scores (Rapid Upper Limb Assessment - RULA), self-reports of perceived discomfort (Borg scale) and performance score on the buzz-wire being recorded and compared. Results show that the Borg scale is not responsive to smaller changes in discomfort whereas RULA and EMG can be used to detect more detailed changes in discomfort, effort and ergonomics.

    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.

    Full Text Available Comfort has a great importance in the interior design of tractor and agricultural machinery cabins. Operators are exposed to muscoskeletal system disorders since they spend long time periods during the day in these vehicles. There is a few work in the literature reporting operators’ opinions about cabin comfort of these machineries. In this study, a questionnaire was conducted in order to get information about agricultural machinery operators’ opinions about the comfort of their vehicles. Tractor cabins and combine harvester machine cabins were selected as machineries. The study was conducted in Eskişehir in Turkey. Questionnaire was composed of four groups of questions and five ordered response levels were used in the Likert's scale. Demographic questions, general questions about the machine, personal evaluation questions and open ended questions were asked to the operators. After the questionnaire completed, collected data were classified according to the machine type. Frequency tables were used to present the results. Visibility and the accessibility were the most satisfied issues for the tractor operators with 55.9% and 55.4% percentages, respectively. Seat comfort has the highest satisfaction degree with 43.7% for the combine harvester operators. Cronbach Alpha reliability coefficient was used for the satisfaction questions in the applied questionnaire. The reliability of the study was high with coefficients of 0.878 and 0.940 for the tractor and combine harvester questionnaires, respectively. This study will support design and development process of new products by considering operator opinions.

    Full Text Available Abstract Background Intimate partner violence (IPV is a widespread public health problem and training of health professions students has become common. Understanding students' prior knowledge, attitudes and personal exposure to IPV will aid educators in designing more effective curriculum. As interprofessional educational efforts proliferate, understanding differences across disciplines will be critical. Findings Students in the schools of Medicine, Nursing and Rehabilitation at a university in Ontario attend an annual daylong interprofessional IPV training. To measure perceived role and comfort with IPV and prior personal exposure, we administered a brief Likert scale survey to a convenience sample of students over three years. 552 students completed the survey; the overall response rate was 73%. The majority (82% agreed that it was their role to intervene in cases of IPV; however Rehabilitation students expressed lower overall comfort levels than did their peers in other schools (p Conclusion While the majority of professional students believe it is their role to address IPV in clinical practice, comfort level varied significantly by field of study. More than one fifth of the students reported some personal exposure to IPV. However this did not impact their level of comfort in addressing this issue. Educators need to take students' preexisting attitudes and personal exposure into account when planning curriculum initiatives in this area.

    The aim of this study is to determine optimum hybrid heating systems parameters, such as temperature, surface area of a radiant heater and vent area to have thermal comfort conditions. DOE, Factorial design method is used to determine the optimum values for input parameters. A 3D model of a virtual standing thermal manikin with real dimensions is considered in this study. Continuity, momentum, energy, species equations for turbulent flow and physiological equation for thermal comfort are numerically solved to study heat, moisture and flow field. K - ɛRNG Model is used for turbulence modeling and DO method is used for radiation effects. Numerical results have a good agreement with the experimental data reported in the literature. The effect of various combinations of inlet parameters on thermal comfort is considered. According to Pareto graph, some of these combinations that have significant effect on the thermal comfort require no more energy can be used as useful tools. A better symmetrical velocity distribution around the manikin is also presented in the hybrid system.

    There has been increasing interest in patient dose reduction in neonatal intensive care units. Removing comfort pads for radiography has been identified as a potential means to decrease patient dose. To assess the effect of comfort pads and support trays on detector entrance exposure (DEE) and image quality for neonatal radiography, and its implication for patient dose. Comfort pads and support trays from three incubator and warmer systems were examined. The attenuation of the primary beam by these structures was measured using a narrow beam geometry. Their effect on DEE and image quality was then assessed using typical neonatal chest radiography techniques with three configurations: (1) both the comfort pad and support included in the beam, (2) only the support tray included and (3) both the comfort pad and support tray removed. Comfort pads and support trays were found to attenuate the primary beam by 6-15%. Eliminating these structures from the X-ray beam's path was found to increase the detector entrance exposure by 28-36% and increase contrast-to-noise ratio by more than 21%, suggesting room for patient dose reduction when the same image quality is maintained. Comfort pads and tray support devices can have a considerable effect on DEE and image quality, with large variations among different incubator designs. Positioning the image detector directly underneath neonatal patients for radiography is a potential means for patient dose reduction. However, such benefit should be weighed against the risks of moving the patient. (orig.)

    Residential ventilation systems with a heat recovery contribute to the improvement of the air quality and to the reduction of heat losses caused by ventilation. An additional opening of the windows in residential buildings results in a clearly increasing consumption of thermal heat because the thermal heat of the out coming air cannot be utilized furthermore. Continuous information on the energetic effects of the opening of windows is helpful. Under this aspect, the authors of the contribution under consideration report on the development of energy efficient comfort ventilation systems with an air quality controlled volume flow rate and continuous detection of the status of the windows aperture. The contribution under consideration is the third part of a project concerning to this theme. This part encompasses a field test with four single-family houses in which the air quality control as well as the detection of the status of the windows aperture is tested and optimized for a long period. This contribution also contains the results of the second part of the project. The second project investigate the technical implementation of a air quality regulation at prototypes and test facilities.

    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.

    2017-10-01

    Thermal comfort determines the state of satisfaction of a person or group of people with thermal conditions of the environment in which the person or group of persons is staying. This state of satisfaction depends on the balance between the amount of heat generated by the body’s metabolism, and the dissipation of heat from the body to the surrounding environment. Due to differences in body build, metabolism, clothing etc. individuals may feel the parameters of the environment in which they are staying differently. Therefore, it is impossible to ensure the thermal comfort of all users of the room. However, properly designed building systems (heating, ventilation, air conditioning) allow for creating optimal thermal conditions that will evaluated positively by the vast majority of users. Due to the fact that currently we spend even 100% of the day indoors, the subject becomes extremely important. The article presents the evaluation of thermal comfort in rooms heated with a tiled fireplace with the function of accumulation of heat using the PMV (Predicted Mean Vote) and PPD (Predicted Percentage Dissatisfied) indices. It also presents the results of studies, on the quality of the micro-climate in such spaces. The system of heating premises described in the article is not a standard solution, but is now more and more commonly used as a supplement to the heating system, or even as a primary heating system in small objects, e.g. single-family houses, seasonal homes, etc. The studies comprised the measurements and analysis of typical internal micro-climate parameters: temperature, relative humidity and CO2 concentration. The results obtained did not raise any major reservations. In order to fully assess the conditions of use, the evaluation of thermal comfort of the analyzed rooms was made. Therefore, additionally the temperature of radiation of the surrounding areas, and the insulation of the users’ clothing was determined. Based on the data obtained, the PPD and PMV

    Professional psychologists who work with gay men have noted that traditional masculine ideals play a prominent role in the gay community whereby some endorse these traditional ideals and stigmatize effeminate behavior by other gay men. One hypothesis is that this behavior reflects negative feelings about being gay. This article examined this hypothesis by reporting the results of an online survey of 622 self-identified gay men. Participants completed the Gender Role Conflict Scale, Lesbian and Gay Identity Scale, the Social Desirability Scale, and questions related to the importance of masculinity. Results showed that most participants valued the public appearance of masculinity; and they ideally wished to be more masculine than they felt they were (Cohen's d = 0.42). A multiple regression analysis showed that the degree to which they valued masculinity and were concerned with violating masculine ideals was positively related with negative feelings about being gay (Cohen's f(2) = .67). These findings highlight the importance of exploring the role that masculine ideals play in gay client's lives given that negative feelings about oneself can adversely affect psychological well-being.

    The aim of the study on the title subject is to determine the environmental impact of so-called sustainable and environment-friendly comfort services which are offered to individual consumers from a central point. The comfort services discussed in this report are a laundry service, delivery or messenger service, and a meal service or domestic caterer. [Dutch] Mensen die werk en prive(of zorg) combineren, leiden een druk bestaan, waardoor de behoefte bestaat om bijvoorbeeld huishoudelijke taken efficient in te richten. Verhoging van gemak en comfort gaat echter vaak gepaard met een toename van de milieudruk: meer apparatuur, dus hogere energieverbruik, en meer behoefte aan mobiliteit. Voor het Ministerie van VROM ligt de uitdaging in het zoeken naar kansen die zowel gemak opleveren als winst voor het milieu. en mogelijk concept hiervoor wordt gezien in zogenaamde 'duurzame gemaksdiensten', zoals een was-, boodschappen- en een maaltijdservice, die aangeboden worden op een centraal punt: het dienstenknooppunt. Elk van deze services blijkt kansen te bieden, varierend van reducties in energiegebruik (max. 36% per huishouden per jaar) tot een (forse) reductie van het aantal gereden autokilometers. oordat deze kansen echter optimaal benut kunnen worden, is een aantal aspecten van belang om verder te onderzoeken: de werkelijke vraag naar duurzame gemaksdiensten vanuit de consument, de locatie van het dienstenknooppunt en het vervoer op en rondom het knooppunt.

    A three-part series presents the development of models for predicting the local thermal sensation (Part I) and local thermal comfort (Part II) of different parts of the human body, and also the whole-body sensation and comfort (Part III) that result from combinations of local sensation and comfort. The models apply to sedentary activities in a range of environments: uniform and non-uniform, stable and transient. They are based on diverse findings from the literature and from body-part-specific human subject tests in a climate chamber. They were validated against a test of automobile passengers. The series is intended to present the models' rationale, structure, and coefficients, so that others can test them and develop them further as additional empirical data becomes available. A) The whole-body (overall) sensation model has two forms, depending on whether all of the body's segments have sensations effectively in the same direction (e.g warm or cool), or whether some segments have sensations opposite to those of the rest of the body. For each, individual body parts have different weights for warm versus cool sensations, and strong local sensations dominate the overall sensation. If all sensations are near neutral, the overall sensation is close to the average of all body sensations. B) The overall comfort model also has two forms. Under stable conditions, people evaluate their overall comfort by a complaint-driven process, meaning that when two body parts are strongly uncomfortable, no matter how comfortable the other body parts might be, the overall comfort will be near the discomfort level of the two most uncomfortable parts. When the environmental conditions are transient, or people have control over their environments, overall comfort is better than that of the two most uncomfortable body parts. This can be accounted for by adding the most comfortable vote to the two most uncomfortable ones. (author)

    2017-12-01

    Little can be found in the literature about thermal comfort and indoor air quality (IAQ) in law enforcement workplaces. This study, based on environmental surveys carried out by the Centro Sanitario Polifunzionale of Milan (Italian State Police Health Service Department), aims to assess the thermal comfort and IAQ in some of the Italian State Police workplaces. Measurements were performed in some indoor workplaces such as offices, archives, laboratories and guard-houses in various regions (Lombardia, Emilia Romagna, Liguria, Veneto, Trentino Alto-Adige) of Northern Italy. The PMV/PPD model developed by Fangar for the evaluation of the thermal comfort was used. We measured both CO2 concentration and relative humidity indoor levels for the evaluation of IAQ. We used Chi square and t Student tests to study both prevalence of thermal discomfort and low IAQ, and their differences between summer and winter. For the purposes of the present study we carried out 488 measurements in 36 buildings (260 in winter and 228 in summer). Our results showed that thermal comfort was reached in 95% and 68% of environmental measurements (in winter and summer, respectively). In summer, we measured different types of thermal discomfort. As regard to IAQ, CO2 exceeded the threshold limit value (1000 ppm) in 39% (winter) and 9% (summer) of our measurements. Chi-square test showed a statistically significant difference between summer and winter for all outcomes considered. Indeed, thermal comfort was better in winter than summer (X2 = 61.0795), while IAQ was found to be better in the summer than winter considering both the CO2 1000 ppm and 1200 ppm threshold values (X2 = 56.9004 and X2 = 8.8845 respectively). Prevalence of low relative humidity in winter was higher than in summer (X2 = 124.7764). Even though this study did not report any situation of risk to Italian police officers health and safety, it has highlighted some potential issues in some of the examined workplaces, concerning

    Tracheostomy is a critical and often life-saving intervention, but associated risks are not negligible. The vulnerability of the pediatric population underlies the importance of caregiver comfort and competence in tracheostomy care. To assess inpatient nursing staff and parental perspectives in managing tracheostomy care. Cross-sectional analysis of survey data from (1) a volunteer sample of inpatient nurses in a tertiary care, freestanding pediatric hospital in the Midwest, assigned to clinical wards that provide care for children with tracheostomy tubes and (2) a consecutive sample of families whose child underwent tracheostomy tube placement at the same institution between March 1 and December 31, 2013. Nurse and parental comfort in managing acute and established tracheostomy tubes. Nursing data were analyzed with attention to years' experience and primary unit of practice. Respondents included 129 of 820 nurses (16% response rate) and family members of 19 of 38 children (50% response rate). When queried about changing established tracheostomies, 59 of 128 nurses (46%) reported being "totally comfortable," including 46 of 82 intensive care unit (ICU) nurses (56%) vs 13 of 46 floor nurses (28%) (P = .002) and 48 of 80 nurses with at least 5 years' experience (60%) vs 12 of 49 less experienced nurses (24%) (P tracheostomy, 61 nurses (47%) described being completely uncomfortable, including 27 of 83 ICU nurses (33%) vs 34 of 46 floor nurses (73%) (P = .006), and 33 of 80 nurses with at least 5 years' experience (41% ) vs 28 of 49 less experienced nurses (57%) (P = .03). Most families felt prepared for discharge (16 of 17 [94%]) and found the health care team accessible (16 of 17 [94%]), although only 5 of 18 families (28%) indicated that tracheostomy teaching was consistent. Nurses' comfort with tracheostomy was higher among nurses with at least 5 years' experience and primary ICU location. Whereas parental comfort with tracheostomy care was high

    Environmental conditions such as lighting and thermal comfort are influencing factors on sleep quality and visual tiredness. The purpose of this study was the determination of the relationship between thermal comfort and light intensity with the sleep quality and eye fatigue in shift nurses. Method. This cross-sectional research was conducted on 82 shift-work personnel of 18 nursing workstations in Isfahan Al-Zahra Hospital, Iran, in 2012. Heat stress monitoring (WBGT) and photometer (Hagner Model) were used for measuring the thermal conditions and illumination intensity, respectively. To measure the sleep quality, visual tiredness, and thermal comfort, Pittsburg sleep quality index, eye fatigue questionnaire, and thermal comfort questionnaire were used, respectively. The data were analyzed with descriptive statistics, Student's t-test, and Pearson correlation. Results. Correlation between thermal comfort which was perceived from the self-reporting of people with eye tiredness was −0.38 (P = 0.002). Pearson correlation between thermal comfort and sleep quality showed a positive and direct relationship (r = 0.241, P = 0.33) but the correlation between thermal comfort, which was perceived from the self-reporting of shift nurses, and WBGT index was a weak relationship (r = 0.019). Conclusion. Based on the obtained findings, it can be concluded that a defect in environmental conditions such as thermal conditions and light intensity and also lack of appropriate managerial plan for night shift-work nurses are destructive and negative factors for the physical and mental health of this group of practitioners.

    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.

    Researchers working with thermal comfort have been using enthalpy to measure thermal energy inside rural facilities, establishing indicator values for many situations of thermal comfort and heat stress. This variable turned out to be helpful in analyzing thermal exchange in livestock systems. The animals are exposed to an environment which is decisive for the thermoregulatory process, and, consequently, the reactions reflect states of thermal comfort or heat stress, the last being responsable for problems of sanity, behavior and productivity. There are researchers using enthalpy as a qualitative indicator of thermal environment of livestock such as poultry, cattle and hogs in tropical regions. This preliminary work intends to check different enthalpy equations using information from classical thermodynamics, and proposes a direct equation as thermal comfort index for livestock systems.

    Thermal and acoustic comfort, inside a vehicle's cabin, are highly interconnected and can greatly influence the health of the passengers. On one hand, the H.V.A.C. system brings the interior air parameters to a comfortable value while on the other hand, it is the main source of noise. It is an intriguing task to find a balance between the two. In this paper, several types of air diffusers were used in order to optimize the ratio between thermal and acoustic interior comfort. Using complex measurements of noise and thermal comfort parameters we have determined for each type of air diffuser the sound pressure level and its impact on air temperature and air velocity.

    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

    Conversely to behaviorist ideas, recent studies suggest that introspection can be accurate and reliable. However, an unresolved question is whether people are able to report specific aspects of their phenomenal experience, or whether they report more general nonspecific experiences. To address this question, we investigated the sensitivity and validity of our introspection for different types of conflict. Taking advantage of the congruency sequence effect, we dissociated response conflict while keeping visual conflict unchanged in a Stroop and in a priming task. Participants were subsequently asked to report on either their experience of urge to err or on their feeling of visual conflict. Depending on the focus of the introspection, subjective reports specifically followed either the response conflict or the visual conflict. These results demonstrate that our introspective reports can be sensitive and that we are able to dissociate specific aspects of our phenomenal experiences in a valid manner.

    Pain is influenced by many factors other than external sources of tissue damage. Among these, the clinician-patient relationship is particularly important for pain diagnosis and treatment. However, the effects of the clinician-patient relationship on pain remain underexamined. We tested the hypothesis that patients who believe they share core beliefs and values with their clinician will report less pain than patients who do not. We also measured feelings of perceived clinician-patient similarity and trust to see if these interpersonal factors influenced pain. We did so by experimentally manipulating perceptions of similarity between participants playing the role of clinicians and participants playing the role of patients in simulated clinical interactions. Participants were placed in 2 groups on the basis of their responses to a questionnaire about their personal beliefs and values, and painful thermal stimulation was used as an analog of a painful medical procedure. We found that patients reported feeling more similarity and trust toward their clinician when they were paired with clinicians from their own group. In turn, patients' positive feelings of similarity and trust toward their clinicians-but not clinicians' feelings toward patients or whether the clinician and patient were from the same group-predicted lower pain ratings. Finally, the most anxious patients exhibited the strongest relationship between their feelings about their clinicians and their pain report. These findings increase our understanding of context-driven pain modulation and suggest that interventions aimed at increasing patients' feelings of similarity to and trust in health care providers may help reduce the pain experienced during medical care. We present novel evidence that the clinician-patient relationship can affect the pain experienced during medical care. We found that "patients" in simulated clinical interactions who reported feeling more similarity and trust toward their

Present results confirm that WBGT applies better to hot climates and outdoor thermal comfort, but not so for hot, humid climates and indoor thermal comfort. Self-reported (subjective) thermal comfort also differed from measured (objective) thermal comfort and across participants because acclimatized individuals can have different sensitivities and acceptance towards (dis)comfort arising from pedestrian movement across spaces. Finally, we suggest that future pedestrian thermal comfort studies employ longitudinal studies and traverse measurements to consider the critical aspects of thermal history and individual sensitivities to on (dis)comfort levels.

  2. Creating high performance buildings: Lower energy, better comfort

    International Nuclear Information System (INIS)

    Brager, Gail; Arens, Edward

    2015-01-01

    Buildings play a critical role in the challenge of mitigating and adapting to climate change. It is estimated that buildings contribute 39% of the total U.S. greenhouse gas (GHG) emissions [1] primarily due to their operational energy use, and about 80% of this building energy use is for heating, cooling, ventilating, and lighting. An important premise of this paper is about the connection between energy and comfort. They are inseparable when one talks about high performance buildings. Worldwide data suggests that we are significantly overcooling buildings in the summer, resulting in increased energy use and problems with thermal comfort. In contrast, in naturally ventilated buildings without mechanical cooling, people are comfortable in much warmer temperatures due to shifting expectations and preferences as a result of occupants having a greater degree of personal control over their thermal environment; they have also become more accustomed to variable conditions that closely reflect the natural rhythms of outdoor climate patterns. This has resulted in an adaptive comfort zone that offers significant potential for encouraging naturally ventilated buildings to improve both energy use and comfort. Research on other forms for providing individualized control through low-energy personal comfort systems (desktop fans, foot warmed, and heated and cooled chairs) have also demonstrated enormous potential for improving both energy and comfort performance. Studies have demonstrated high levels of comfort with these systems while ambient temperatures ranged from 64–84°F. Energy and indoor environmental quality are inextricably linked, and must both be important goals of a high performance building

  7. Impact of measurable physical phenomena on contact thermal comfort

    Fojtlín, Miloš; Pokorný, Jan; Fišer, Jan; Toma, Róbert; Tuhovčák, Ján

    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.

    Air conditioning in offices has become a current practice in North Western Europe. The main reasons for that are high internal loads, solar gains and increased comfort expectations. Hence, the move away from the naturally ventilated cellular office increased thermal comfort complaints. The paper presents two cases. In both the results of a comfort enquiry are compared with measurements. The enquiries gave numbers of dissatisfied at a PMV zero that were much higher than the standard PMV/PPD curve does. Measurements instead showed that in one of the two offices only comfort complaints could be expected in summer. But even then, the enquired severity of complaints could not be related to the measured data. Several hypotheses are forwarded to explain the results. Individuals interpret the -3 to +3 scale for thermal sensation differently, which has a direct impact on the number of dissatisfied. The standard curve further-on is a most significant mean of thousands of steady state comfort votes under well-controlled conditions while an on site enquiry involves much smaller numbers of people. These have a clear expectation: an improvement of comfort condition, thanks to the study. For that reason they may exaggerate their complaints when enquired. And finally, an alternative PMV versus PPD curve, published in literature, shows more people complaining at a given PMV than the standard curve forwards. (author)

    Skin regions differ in their sensitivity to temperature stimuli. The present study examined whether such regional differences were also evident in the perception of thermal comfort. Regional thermal comfort was assessed in males (N=8) and females (N=8), by having them regulate the temperature of the water delivered to a water-perfused suit (WPS), within a temperature range considered thermally comfortable. In separate trials, subjects regulated the temperature of the WPS, or specific regions of the suit covering different skin areas (arms, legs, front torso and back torso). In the absence of subjective temperature regulation (TR), the temperature changed in a sinusoidal manner from 10°C to 50°C; by depressing a switch and reversing the direction of the temperature at the limits of the thermal comfort zone (TCZ), each subject defined TCZ for each body region investigated. The range of regulated temperatures did not differ between genders and skin regions. Local Tsk at the lower and upper limits of the TCZ was similar for both genders. Higher (pthermally comfortable conditions, the well-established regional differences in thermosensitivity are not reflected in the TCZ, with similar temperature preferences by both genders. Thermal comfort of different skin regions and overall body is not achieved at a single skin temperature, but at range of temperatures, defined as the TCZ. Copyright © 2016 Elsevier Inc.

  10. Neural computing thermal comfort index for HVAC systems

    2005-01-01

    The primary purpose of a heating, ventilating and air conditioning (HVAC) system within a building is to make occupants comfortable. Without real time determination of human thermal comfort, it is not feasible for the HVAC system to yield controlled conditions of the air for human comfort all the time. This paper presents a practical approach to determine human thermal comfort quantitatively via neural computing. The neural network model allows real time determination of the thermal comfort index, where it is not practical to compute the conventional predicted mean vote (PMV) index itself in real time. The feed forward neural network model is proposed as an explicit function of the relation of the PMV index to accessible variables, i.e. the air temperature, wet bulb temperature, globe temperature, air velocity, clothing insulation and human activity. An experiment in an air conditioned office room was done to demonstrate the effectiveness of the proposed methodology. The results show good agreement between the thermal comfort index calculated from the neural network model in real time and those calculated from the conventional PMV model

    With rapid urbanization, the demand for elevators is increasing, and their level of safety and ride comfort under vibrating conditions has also aroused interest. It is therefore essential to monitor the ride comfort level of elevators. The traditional method for such monitoring depends significantly on regular professional inspections, and requires expensive equipment and professional skill. With this regard, a new method for elevator ride comfort monitoring using a smartphone is demonstrated herein in detail. A variety of high-precision sensors are installed in a smartphone with strong data processing and telecommunication capabilities. A series of validation tests were designed and completed, and the international organization for standardization ISO2631-1997 was applied to evaluate the level of elevator ride comfort. Experimental results indicate that the proposed method is stable and reliable, its precision meets the engineering requirements, and the elevator ride comfort level can be accurately monitored under various situations. The method is very economical and convenient, and provides the possibility for the public to participate in elevator ride comfort monitoring. In addition, the method can both provide a wide range of data support and eliminate data errors to a certain extent.

    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.

    Patients frequently complain of back pain after cardiac catheterization, and there is a lack of evidence to guide practice regarding patient comfort while maintaining hemostasis at femoral access site after cardiac catheterization. The aim of this study was to examine if frequent position changes affect a patient's pain level or increase incidents of bleeding in the recovery period after cardiac catheterization. A quasi-experimental pretest/posttest design was used to evaluate a patient's reported pain levels and positioning changes during bed rest period postprocedure. Twenty charts were reviewed to note documentation of patient position, self-reported pain rating related to pain relief goals, and occurrence of bleeding at the procedure site. A survey was conducted to reveal nurse attitudes, knowledge, and beliefs regarding positioning and pain management for patients in the post-cardiac catheterization period. Results from this survey were used to develop education and data collection tools. Education regarding perceived barriers and importance of maximizing activity orders for patient comfort was provided to nursing staff. After nurse education, an additional 20 charts were reviewed to note if increasing frequency of position change affects pain levels reported by patients or if any increased incidence of bleeding was noted with greater frequency of position change. Data were analyzed using correlation analyses. Greater levels of pain were associated with higher pain ratings (r = 0.796, P position change only as a comfort measure was negatively associated with pain ratings; in other words, lower patient pain ratings were associated with use of positioning only without addition of medications to address complaint (r = -0.493, P position changes for comfort after cardiac catheterization. This initial analysis suggests position changes in conjunction with pain medication are beneficial in managing pain after cardiac catheterization. There was no increase in

    "Comfort women" refers to young women and girls who were forced into sexual slavery by the Imperial Japanese military during World War II. They were abducted from their homes in countries under Imperial Japanese rule, mostly from Korea, and the rest from China, Philippines, Malaysia, Taiwan, Indonesia, the Netherlands, etc. "Comfort women" endured extreme trauma involving rape, sexual torture, physical abuse, starvation, threats of death, and witnessed many others being tortured and killed. This article reviews all the studies that have investigated the psychiatric or psychosocial sequelae of the survivors of the Japanese military sexual slavery. Most importantly, a recent study which conducted a psychiatric evaluation on the former "comfort women" currently alive in South Korea is introduced. The participants' unmarried rate was relatively high and their total fertility rate was relatively low. Majority of the participants reported having no education and being the low economic status. They showed high current and lifetime prevalence of posttraumatic disorder, major depressive disorder, somatic symptom disorder, social anxiety disorder, panic disorder, and alcohol use disorder. Participants showed high suicidality and majority of the participants still reported being ashamed of being former "comfort women" after all these years. This article high-lights the fact that the trauma has affected the mental health and social functioning of former "comfort women" throughout their lives, and even to the present day.

    Full Text Available Our purpose is to look into one of the social problems affecting the most to older people, namely the feeling of loneliness. We intend to approach this problem differentiating its social and emotional dimensions. Through a qualitative methodological strategy ?focus groups as procedure to raise data and Grounded Theory as analytical perspective? we study how that feeling is experienced among a profile of older persons particularly affected by loneliness: older widowed persons living alone. Our findings prove that these persons suffer from emotional loneliness, especially those who enter widowhood at a later age and after decades of marriage. This feeling is linked to the loss of their spouse and it is at night when it is more likely to emerge. Moreover, widowhood comes along with the risk of social loneliness because of the relational distancing from friends who used to be connected to the married couple. We have identified as well gender differences regarding the impact of loneliness, being men those who are especially frail to confront it.

    Full Text Available With increasing consumer requirements, farmers and vendors see the importance of social media as a marketing tool to engage with consumers. In particular, on a more personal level for reasons of brand management. Instagram is becoming increasingly popular as a marketing communication tool. The aim of this paper is to identify areas that users evaluate in terms of positive feelings in connection with farmers’ markets. The results are based on the analysis of the worldwide, and Czech, instagram social network. Instagram posts were identified on the basis of keywords, such as #farmarsketrhy and #farmersmarkets. The results of the study are based on 100,000 contributions on Instagram made by 55,632 users. The analysis contains 1,357,812 ‘unique’ words. The results identified six major areas (1 Healthy (2 Good (3 Great (4 Happy (5 Nice (6 Perfect. An appropriately posted hashtag indicated the positive feelings that were evoked and then assigned to a matching category. The research results are used to identify group characteristics that exert these positive feelings while visiting farmers’ markets. These results can be used to build communications campaigns for farmers’ markets. They can also be used as a basis for further research in defining the behaviour of farmers’ markets visitors, based on cultural differences arising from geographic location.

  1. Models of Affective Decision Making: How Do Feelings Predict Choice?

    Intuitively, how you feel about potential outcomes will determine your decisions. Indeed, an implicit assumption in one of the most influential theories in psychology, prospect theory, is that feelings govern choice. Surprisingly, however, very little is known about the rules by which feelings are transformed into decisions. Here, we specified a computational model that used feelings to predict choices. We found that this model predicted choice better than existing value-based models, showing a unique contribution of feelings to decisions, over and above value. Similar to the value function in prospect theory, our feeling function showed diminished sensitivity to outcomes as value increased. However, loss aversion in choice was explained by an asymmetry in how feelings about losses and gains were weighted when making a decision, not by an asymmetry in the feelings themselves. The results provide new insights into how feelings are utilized to reach a decision. © The Author(s) 2016.

    To explore the emotion of feeling cared for in the workplace. The emotion of feeling cared for drives health-promoting behaviours. Feeling cared for is the end-product of caring, affecting practice, environment and outcomes. Identifying behaviours that lead to feeling cared for is the first step in promoting caring practices in leadership. A survey with open-ended questions was designed, validated and electronically distributed. Data from 35 responses were thematically analysed. Unit culture and leadership style affect caring capacity in the workplace. First level coding revealed two caring behaviour categories: recognition and support. Themes emerged aligned to Chapman's model of workplace appreciation: words of affirmation, receiving gifts, quality time and acts of service. The importance of being treated as a whole person was reported: being appreciated personally and professionally. Feeling cared for drives outcomes such as feeling valued, important, teamwork and organisational loyalty. This study generalises the applicability of Chapman's model developed for workplace appreciation in the health-care setting. Concrete examples of how leaders stimulate feeling cared for are provided. Caring leadership behaviours have the potential to improve retention, engagement, the healing environment and the capacity for caring for others. © 2016 John Wiley & Sons Ltd.

    Evidence is accumulating for the importance of feelings of risk in explaining cancer preventive behaviours, but best practices for influencing these feelings are limited. The aim of this experimental study was to compare the effects of narrative and non-narrative risk communication about sunbed use on ease of imagination and feelings of cancer risk. A total of 233 female sunbed users in the general Dutch population were randomly assigned to one of three conditions: a narrative message (i.e., personal testimonial), a non-narrative cognitive message (i.e., factual risk information using cognitive-laden words), or a non-narrative affective message (i.e., factual risk information using affective-laden words). Ease of imagination and feelings of risk were assessed directly after the risk information was given (T1). Three weeks after the baseline session, feelings of risk were measured again (T2). The results revealed that sunbed users who were exposed to narrative risk information could better imagine themselves developing skin cancer and reported higher feelings of skin cancer risk at T1. Moreover, ease of imagination mediated the effects of message type on feelings of risk at T1 and T2. The findings provide support for the effects of narrative risk communication in influencing feelings of cancer risk through ease of imagination. Cancer prevention programmes may therefore benefit from including narrative risk information. Future research is important to investigate other mechanisms of narrative information and their most effective content and format. What is already known on this subject? Evidence is growing for the importance of feelings of risk in explaining cancer preventive behaviours. Narratives have increasingly been considered as an effective format for persuasive risk messages and studies have shown narrative risk communication to be effective in influencing cognitive risk beliefs. What does this study add? Increasing understanding of how feelings of cancer

    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 analysis was performed according to two different configurations: in "spontaneous

    In two studies, we examined how expressions of guilt and shame affected person perception. In the first study, participants read an autobiographical vignette in which the writer did something wrong and reported feeling either guilt, shame, or no emotion. The participants then rated the writer's motivations, beliefs, and traits, as well as their own feelings toward the writer. The person expressing feelings of guilt or shame was perceived more positively on a number of attributes, including moral motivation and social attunement, than the person who reported feeling no emotion. In the second study, the writer of the vignette reported experiencing (or not experiencing) cognitive and motivational aspects of guilt or shame. Expressing a desire to apologise (guilt) or feelings of worthlessness (private shame) resulted in more positive impressions than did reputational concerns (public shame) or a lack of any of these feelings. Our results indicate that verbal expressions of moral emotions such as guilt and shame influence perception of moral character as well as likeability.

    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.

    This article presents findings of the thermal comfort study in hospitals. A field survey was conducted to investigate the temperature range for thermal comfort in hospitals in the tropics. Thermal acceptability assessment was conducted to examine whether the hospitals in the tropics met the ASHRAE Standard-55 80% acceptability criteria. A total of 114 occupants in four hospitals were involved in the study. The results of the field study revealed that only 44% of the examined locations met the comfort criteria specified in ASHRAE Standard 55. The survey also examined the predicted percentage of dissatisfied in the hospitals. The results showed that 49% of the occupants were satisfied with the thermal environments in the hospitals. The field survey analysis revealed that the neutral temperature for Malaysian hospitals was 26.4 degrees C. The comfort temperature range that satisfied 90% of the occupants in the space was in the range of 25.3-28.2 degrees C. The results from the field study suggested that a higher comfort temperature was required for Malaysians in hospital environments compared with the temperature criteria specified in ASHRAE Standard (2003). In addition, the significant deviation between actual mean vote and predicted mean vote (PMV) strongly implied that PMV could not be applied without errors in hospitals in the tropics. The new findings on thermal comfort temperature range in hospitals in the tropics could be used as an important guide for building services engineers and researchers who are intending to minimize energy usage in heating, ventilating and air conditioning systems in hospitals operating in the tropics with acceptable thermal comfort level and to improve the performance and well-being of its workers.

    Highlights: • We review studies of thermal comfort and discuss building energy use implications. • Adaptive comfort models tend to have a wider comfort temperature range. • Higher indoor temperatures would lead to fewer cooling systems and less energy use. • Socio-economic study and post-occupancy evaluation of built environment is desirable. • Important to consider future climate scenarios in heating, cooling and power schemes. - Abstract: Buildings account for about 40% of the global energy consumption and contribute over 30% of the CO 2 emissions. A large proportion of this energy is used for thermal comfort in buildings. This paper reviews thermal comfort research work and discusses the implications for building energy efficiency. Predicted mean vote works well in air-conditioned spaces but not naturally ventilated buildings, whereas adaptive models tend to have a broader comfort temperature ranges. Higher indoor temperatures in summertime conditions would lead to less prevalence of cooling systems as well as less cooling requirements. Raising summer set point temperature has good energy saving potential, in that it can be applied to both new and existing buildings. Further research and development work conducive to a better understanding of thermal comfort and energy conservation in buildings have been identified and discussed. These include (i) social-economic and cultural studies in general and post-occupancy evaluation of the built environment and the corresponding energy use in particular, and (ii) consideration of future climate scenarios in the analysis of co- and tri-generation schemes for HVAC applications, fuel mix and the associated energy planning/distribution systems in response to the expected changes in heating and cooling requirements due to climate change

    Chronically stressed rodents who are allowed to eat calorie-dense "comfort" food develop greater mesenteric fat, which in turn dampens hypothalamic-pituitary-adrenocortical (HPA) axis activity. We tested whether similar relations exist in humans, at least cross-sectionally. Fifty-nine healthy premenopausal women were exposed to a standard laboratory stressor to examine HPA response to acute stress and underwent diurnal saliva sampling for basal cortisol and response to dexamethasone administration. Based on perceived stress scores, women were divided into extreme quartiles of low versus high stress categories. We found as hypothesized that the high stress group had significantly greater BMI and sagittal diameter, and reported greater emotional eating. In response to acute lab stressor, the high stress group showed a blunted cortisol response, lower diurnal cortisol levels, and greater suppression in response to dexamethasone. These cross-sectional findings support the animal model, which suggests that long-term adaptation to chronic stress in the face of dense calories result in greater visceral fat accumulation (via ingestion of calorie-dense food), which in turn modulates HPA axis response, resulting in lower cortisol levels.

    2009-12-01

    A random allocation single blind block design pillow field study was undertaken to investigate the behaviour of cervico-thoracic spine pain in relation to pillow use. Participants (N=106) who reported preference for side sleep position with one pillow were recruited via a telephone survey and newspaper advertisement. They recorded sleep quality and pillow comfort ratings, frequency of retiring and waking cervical pain and duration of waking cervical pain while sleeping for a week on their usual pillow, polyester, foam, feather and rubber pillows of regular shape and a foam contour pillow. Analysis was undertaken comparing sleep quality, pillow comfort, waking and temporal cervical pain reports, between the usual pillow and the trial pillows, between pillows of differing content and foam pillows of differing shape. This study provides evidence to support recommendation of rubber pillows in the management of waking cervical pain, and to improve sleep quality and pillow comfort. The rubber pillow performed better than subjects' own pillow in most instances. Subjects' own pillow performed similarly to foam and polyester pillows, and there is no evidence that the use of a foam contour pillow has advantages over the regular shaped pillows. Feather pillows should not be recommended.

  12. Correlations between social-emotional feelings and anterior insula activity are independent from visceral states but influenced by culture

    Directory of Open Access Journals (Sweden)

    Mary Helen eImmordino-Yang

    2014-09-01

    Full Text Available The anterior insula (AI maps visceral states and is active during emotional experiences, a functional confluence that is central to neurobiological accounts of feelings. Yet, it is unclear how AI activity correlates with feelings during social emotions, and whether this correlation may be influenced by culture, as studies correlating real-time AI activity with visceral states and feelings have focused on Western subjects feeling physical pain or basic disgust. Given psychological evidence that social-emotional feelings are cognitively constructed within cultural frames, we asked Chinese and American participants to report their feeling strength to admiration and compassion-inducing narratives during fMRI with simultaneous electrocardiogram recording. Trial-by-trial, cardiac arousal and feeling strength correlated with ventral and dorsal AI activity bilaterally but predicted different variance, suggesting that interoception and social-emotional feeling construction are concurrent but dissociable AI functions. Further, although the variance that correlated with cardiac arousal did not show cultural effects, the variance that correlated with feelings did. Feeling strength was especially associated with ventral AI activity (the autonomic modulatory sector in the Chinese group but with dorsal AI activity (the visceral-somatosensory/cognitive sector in an American group not of Asian descent. This cultural group difference held after controlling for posterior insula activity and was replicated. A bi-cultural East-Asian American group showed intermediate results. The findings help elucidate how the AI supports feelings and suggest that previous reports that dorsal AI activation reflects feeling strength are culture related. More broadly, the results suggest that the brain’s ability to construct conscious experiences of social emotion is less closely tied to visceral processes than neurobiological models predict and at least partly open to cultural

    Maximizing value in palliative care requires continued development and standardization of communication quality indicators. To describe the basic epidemiology of a newly-adopted patient-centered communication quality indicator for hospitalized palliative care patie9nts with advanced cancer. Cross-sectional analysis of 207 advanced cancer patients who received palliative care consultation at two medical centers in the United States. Participants completed the Heard & Understood quality indicator immediately before and the day following the initial palliative care consultation: "Over the past two days ["24 hours" for the post-consultation version], how much have you felt heard and understood by the doctors, nurses and hospital staff? Completely/Quite a Bit/Moderately/Slightly/Not at All". We categorized "Completely" as indicating ideal quality. Approximately one-third indicated ideal Heard & Understood quality before palliative care consultation. Age, financial security, emotional distress, preferences for comfort-longevity tradeoffs at end-of-life, and prognosis expectations were associated with pre-consultation quality. Among those with less-than-ideal quality at baseline, 56% rated feeling more Heard & Understood the day following palliative care consultation. The greatest pre-post improvement was among people who had unformed end-of-life treatment preferences or who reported having "no idea" about their prognosis at baseline. Most patients felt incompletely heard and understood at the time of referral to palliative care consultation and more than half improved following consultation. Feeling heard and understood is an important quality indicator sensitive to interventions to improve care and key variations in the patient experience. Copyright © 2018. Published by Elsevier Inc.

  14. Design for thermal sensation and comfort states in vehicles cabins

    Alahmer, Ali; Abdelhamid, Mahmoud; Omar, Mohammed

    2012-01-01

    This manuscript investigates the analysis and modeling of vehicular thermal comfort parameters using a set of designed experiments aided by thermography measurements. The experiments are conducted using a full size climatic chamber to host the test vehicle, to accurately assess the transient and steady state temperature distributions of the test vehicle cabin. Further investigate the thermal sensation (overall and local) and the human comfort states under artificially created relative humidity scenarios. The thermal images are calibrated through a thermocouples network, while the outside temperature and relative humidity are manipulated through the climatic environmental chamber with controlled soaking periods to guarantee the steady state conditions for each test scenario. The relative humidity inside the passenger cabin is controlled using a Total Humidity Controller (THC). The simulation uses the experimentally extracted boundary conditions via a 3-D Berkeley model that is set to be fully transient to account for the interactions in the velocity and temperature fields in the passenger compartment, which included interactions from turbulent flow, thermal buoyancy and the three modes of heat transfer conduction, convection and radiation. The model investigates the human comfort by analyzing the effect of the in-cabin relative humidity from two specific perspectives; firstly its effect on the body temporal variation of temperature within the cabin. Secondly, the Local Sensation (LS) and Comfort (LC) are analyzed for the different body segments in addition to the Overall Sensation (OS) and the Overall Comfort (OC). Furthermore, the human sensation is computed using the Fanger model in terms of the Predicted Mean Value (PMV) and the Predicted Percentage Dissatisfied (PPD) indices. The experimental and simulation results show that controlling the RH levels during the heating and the cooling processes (winter and summer conditions respectively) aid the A/C system to

    Poole, Debra Ann; Dickinson, Jason J

    2014-02-01

    This study evaluated the impact of comfort drawing (allowing children to draw during interviews) on the quality of children's eyewitness reports. Children (N=219, 5 to 12 years) who had participated in an earlier memory study returned 1 or 2 years later, experienced a new event, and described these events during phased, investigative-style interviews. Interviewers delivered the same prompts to children in the no drawing and drawing conditions but provided paper and markers in the drawing condition, invited these children to draw, and periodically asked if they would like to make another picture. Most children in the drawing condition were interested in using the materials, and measures of eyewitness performance were sensitive to differences in cognitive ability (i.e., age) and task difficulty (i.e., delay between the remote event and interview). Comfort drawing had no overall impact as evidenced by nonsignificant main effects of condition across 20 performance measures, although more of the younger children reported experienced touching in the drawing than no drawing condition. The children successfully divided attention between voluntary drawing and conversations about past events. Importantly, comfort drawing did not impair the amount of information recalled, the accuracy of children's answers, or even the extent to which interviewers needed to prompt for answers. Due to the large number of analyses, the benefit of drawing for younger, touched children requires replication. Comfort drawing poses no documented risks for typically-developing school-aged children, but the practice remains untested for younger children and those with cognitive impairments.

    Concrete methods of technology-related strategy construction were studied, and a prototype was built. Proposed as a basic concept was a method to follow the steps of the grasping of people's needs, mapping of people's needs, translation of people's needs into technological tasks, and finally the matching of technological tasks and technological seeds. Questionnaires were conducted and it was learned that safety and comfort, computerization, environment, and energy were the needs, and then they were set as the major targets. In this study, a process was taken up in which safety and comfort and computerization develop into technological tasks. A study was made of people's needs on a needs matrix, and intermediate targets in the field of safety and comfort were established. They are the 'building of an environment in which everyone is independent and a participant in social activities,' the 'construction of a safe and comfortable life,' and the 'sustenance and enhancement of good health.' Intermediate targets set for the field of computerization are an 'efficient electric government and administration,' 'information disclosure and distribution on the global scale,' and the 'maintenance of peace and order in the cyberspace.'

    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.

    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.

    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.

    The present study investigates the hitherto neglected influence of the spatial distance between the jealous person, the partner, and a potential rival as a proximate contextual factor regulating emotion intensity. The study tested four predictions. (1) The jealousy mechanism responds with mild negative feelings at most as long as the partner is close to the jealous person. (2) The negative feelings increase when the partner is far from the jealous person but the rival is close. (3) The most uncomfortable feelings result when the partner and the rival are close together and both far from the jealous person. (4) Based on the evolutionary psychological considerations, men report stronger negative feelings than women when suspecting sexual infidelity. Conversely, women report stronger negative feelings than men when suspecting emotional infidelity. The results confirmed predictions 1 and 4. Reversing predictions 2 and 3, the close rival consistently elicited the most uncomfortable feelings. Implications and limitations of the present study are discussed and suggestions for future research are provided.

    Sustaining outdoor life in cities is decreasing because of the recent rapid urbanisation without considering climate-responsive urban design concepts. Such inadvertent climatic modifications at the indoor level have imposed considerable demand on the urban energy resources. It is important to provide comfortable ambient climate at open urban squares. Researchers need to predict the comfortable conditions at such outdoor squares. The main objective of this study is predict the visitors' outdoor comfort indices by using a developed computational model termed as SVM-WAVELET (Support Vector Machines combined with Discrete Wavelet Transform algorithm). For data collection, the field study was conducted in downtown Isfahan, Iran (51°41′ E, 32°37′ N) with hot and arid summers. Based on different environmental elements, four separate locations were monitored across two public squares. Meteorological data were measured simultaneously by surveying the visitors' thermal sensations. According to the subjects' thermal feeling and their characteristics, their level of comfort was estimated. Further, the adapted computational model was used to estimate the visitors’ thermal sensations in terms of thermal comfort indices. The SVM-WAVELET results indicate that R"2 value for input parameters, including Thermal Sensation, PMW (The predicted mean vote), PET (physiologically equivalent temperature), SET (standard effective temperature) and T_m_r_t were estimated at 0.482, 0.943, 0.988, 0.969 and 0.840, respectively. - Highlights: • To explore the visitors' thermal sensation at urban public squares. • This article introduces findings of outdoor comfort prediction. • The developed SVM-WAVELET soft-computing technique was used. • SVM-WAVELET estimation results are more reliable and accurate.

    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)

  9. Guidelines on Thermal Comfort of Air Conditioned Indoor Environment

    Miura, Toyohiko

    The thermal comfort of air conditioned indoor environment for workers depended, of course, on metabolic rate of work, race, sex, age, clothing, climate of the district and state of acclimatization. The attention of the author was directed to the seasonal variation and the sexual difference of comfortable temperature and a survey through a year was conducted on the thermal comfort, and health conditions of workers engaged in light work in a precision machine factory, in some office workers. Besides, a series of experiments were conducted for purpose of determinning the optimum temperature of cooling in summer time in relation to the outdoor temperature. It seemed that many of workers at present would prefer somewhat higher temperature than those before the World War II. Forty years ago the average homes and offices were not so well heated as today, and clothing worn on the average was considerably heavier.

    Full Text Available Daylight plays a significant role in sustainable building design. The purpose of this paper was to investigate the impact of manual solar shades on indoor visual comfort. A developed stochastic model for manual solar shades was modeled in Building Controls Virtual Test Bed, which was coupled with EnergyPlus for co-simulation. Movable solar shades were compared with two unshaded windows. Results show that movable solar shades have more than half of the working hours with a comfortable illuminance level, which is about twice higher than low-e windows, with a less significant daylight illuminance fluctuation. For glare protection, movable solar shades increase comfortable visual conditions by about 20% compared to low-e windows. Moreover, the intolerable glare perception could be reduced by more than 20% for movable solar shades.

  11. Formations of Feeling, Constellation of Things

    Ben Highmore

    2016-03-01

    Full Text Available This essay revisits Raymond Williams’s notion of ‘structures of feeling’ with the intention of clarifying what Williams meant by ‘feelings’, and of exploring the concept’s possible range and reach within the study of culture. It recovers the initial anthropological context for the phrase by reconnecting it to the work of Ruth Benedict and Gregory Bateson. It goes on to suggest that while the analysis of ‘structures of feeling’ has been deployed primarily in studies of literary and filmic culture it might be usefully extended towards the study of more ubiquitous forms of material culture such as clothing, housing, food, furnishings and other material practices of daily living. Indeed it might be one way of explaining how formations of feeling are disseminated, how they suture us to the social world and how feelings are embedded in the accoutrements of domestic, habitual life. The essay argues that by joining together a socially phenomenological interest in the world of things, accompanied by an attention to historically specific moods and atmospheres, ‘structures of feelings’ can direct analyses towards important mundane cultural phenomena.

    In the coming decades, global warming and increase in temperature, in different regions of the world, may change indoor and outdoor thermal comfort conditions and human health. The aim of this research was to study the effects of global warming on thermal comfort conditions in indoor ambiences in Iran. To study the increase in temperature, model for assessment of greenhouse-gas induced climate change scenario generator compound model has been used together with four scenarios and to estimate thermal comfort conditions, adaptive model of the American Society of Heating, Refrigerating and Air-Conditioning Engineers has been used. In this study, Iran was divided into 30 zones, outdoor conditions were obtained using meteorological data of 80 climatological stations and changes in neutral comfort conditions in 2025, 2050, 2075 and 2100 were predicted. In accordance with each scenario, findings from this study showed that temperature in the 30 zones will increase by 2100 to between 3.4 C and 5.6 C. In the coming decades and in the 30 studied zones, neutral comfort temperature will increase and be higher and more intense in the central and desert zones of Iran. The low increase in this temperature will be connected to the coastal areas of the Caspian and Oman Sea in southeast Iran. This increase in temperature will be followed by a change in thermal comfort and indoor energy consumption from 8.6 % to 13.1 % in air conditioning systems. As a result, passive methods as thermal inertia are proposed as a possible solution.

  13. 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.

    Relationships between indoor building conditions and well-being of occupants are complex; many indoor stressors can exert their effects additively or through complex interactions. It has been shown that exposure to these stressors can cause both short-term and long-term effects. Relevant relations between measurements of chemical and physical indoor environmental parameters and effects have been difficult to make. To increase the chance on successful assessment of cause-effect relationships in future indoor environmental quality investigations, there seems to be a need to improve procedures applied to gather the relevant information. [Dutch] Relaties tussen binnenmilieucondities enerzijds en gezondheid en comfort van kantoormedewerkers anderzijds zijn complex. Veel prikkels of stressoren kunnen zowel kortdurende als langdurende effecten veroorzaken. Maar het is ingewikkeld om relevante relaties te leggen tussen deze effecten en metingen van de chemische en fysische binnenmilieuparameters. Het lijkt noodzakelijk om de procedures voor binnenmilieuonderzoek te verbeteren. Dit kan de kans op een succesvolle bepaling van oorzaak/effect-relaties in toekomstige binnenmilieustudies vergroten.

  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.

    The objective of this investigation was to evaluate the level of comfort and ocular dryness during wear with six daily disposable contact lenses (DDCL) and also determine the changes in contact lens equilibrium water content (EWC) resulting from their wear. In this contralateral open trial, 27 subjects were randomly fitted with six DDCL (stenfilcon A, delefilcon A, nelfilcon A, narafilcon A, nesofilcon A, and omafilcon A). The evaluation of comfort and ocular dryness sensation was recorded by the participants at two moments of the day (11 AM and 5 PM) over a period of 10 days of contact lens wear. The assessment was made with the aid of visual analogue scales (0-10). The refractive index of 54 contact lenses was accessed by a single operator using a digital automated refractometer (CLR 12-70; Index Instruments). The EWC of the lenses was estimated based on its refractive index values. Comfort ratings were slightly higher for delefilcon A (9.56±0.67, P=0.01) and narafilcon A (9.40±0.93, P=0.01) and these lenses wearers also reported less ocular dryness. The results revealed a pronounced water content reduction for omafilcon A (P=0.002), narafilcon A (P=0.008), and nesofilcon A (P=0.003). Although changes in subjective responses and EWC were distinct among the materials analyzed, all the contact lenses performed well during the 10 days of wear.

    Purpose The unpleasant acoustic noise is an important drawback of almost every magnetic resonance imaging scan. Instead of reducing the acoustic noise to improve patient comfort, a method is proposed to mitigate the noise problem by producing musical sounds directly from the switching magnetic fields while simultaneously quantifying multiple important tissue properties. Theory and Methods MP3 music files were converted to arbitrary encoding gradients, which were then used with varying flip angles and TRs in both 2D and 3D MRF exam. This new acquisition method named MRF-Music was used to quantify T1, T2 and proton density maps simultaneously while providing pleasing sounds to the patients. Results The MRF-Music scans were shown to significantly improve the patients' comfort during the MRI scans. The T1 and T2 values measured from phantom are in good agreement with those from the standard spin echo measurements. T1 and T2 values from the brain scan are also close to previously reported values. Conclusions MRF-Music sequence provides significant improvement of the patient's comfort as compared to the MRF scan and other fast imaging techniques such as EPI and TSE scans. It is also a fast and accurate quantitative method that quantifies multiple relaxation parameter simultaneously. PMID:26178439

    As part of the fenestration system, the interior shadings have also a role to control the indoor environment to maintain indoor visual comfort. As the occupants have personal access to control these, their control behavior then, might enhance or even worsen indoor comfort performance. The controlling behavior might not only influence indoor comfort performance but can also indicate the success or failure of interior shading as a control device element. This paper is intended to report control behavior patterns, as represented by the variety of the slats’ openings of two types of interior shading i.e. Venetian and Vertical blinds and to analyze these on the concurrent impacts to indoor office building’s indoor illuminance and luminance distribution. The purpose of this research is to figure out the shading control patterns as well as to examine the effectiveness of these two types of interior shadings to control indoor visual environment. This study is a quantitative research using experimentation on the slats’ opening of two types of shadings at two identical office rooms. The research results suggested that both types of blinds seem unsuitable for gaining proper illumination values at work planes in humid tropics area. However, these shadings demonstrate good performance for luminance distribution except for that of the closed Venetian blinds.

    Poor indoor air quality and thermal comfort condition in the workspace affected the occupants’ health and work productivity, especially when adapting the recirculation of air in heating ventilation and air-conditioning (HVAC) system. The recirculation of air was implemented in this study by mixing the circulated returned indoor air with the outdoor fresh air. The aims of this study are to assess the indoor thermal comfort and indoor air quality (IAQ) in the office buildings, equipped with combination filters. The air filtration technique consisting minimum efficiency reporting value (MERV) filter and activated carbon fiber (ACF) filter, located before the fan coil units. The findings of the study show that the technique of mixing recirculation air with the fresh air through the combination filters met the recommended thermal comfort condition in the workspace. Furthermore, the result of the post-occupancy evaluation (POE) and the environmental measurements comply with the ASHRAE 55 standard. In addition, the level of CO2 concentration continued to decrease during the period of the measurement.

    Unpleasant acoustic noise is a drawback of almost every MRI scan. Instead of reducing acoustic noise to improve patient comfort, we propose a technique for mitigating the noise problem by producing musical sounds directly from the switching magnetic fields while simultaneously quantifying multiple important tissue properties. MP3 music files were converted to arbitrary encoding gradients, which were then used with varying flip angles and repetition times in a two- and three-dimensional magnetic resonance fingerprinting (MRF) examination. This new acquisition method, named MRF-Music, was used to quantify T1 , T2 , and proton density maps simultaneously while providing pleasing sounds to the patients. MRF-Music scans improved patient comfort significantly during MRI examinations. The T1 and T2 values measured from phantom are in good agreement with those from the standard spin echo measurements. T1 and T2 values from the brain scan are also close to previously reported values. MRF-Music sequence provides significant improvement in patient comfort compared with the MRF scan and other fast imaging techniques such as echo planar imaging and turbo spin echo scans. It is also a fast and accurate quantitative method that quantifies multiple relaxation parameters simultaneously.

    Federal agencies are taking many steps to improve the sustainability of their operations, including improving the energy efficiency of their buildings, promoting recycling and reuse of materials, encouraging carpooling and alternative transit schemes, and installing low flow water fixture units are just a few of the common examples. However, an often overlooked means of energy savings is to provide feedback to building users about their energy use through information dashboards connected to a building?s energy information system. An Energy Information System (EIS), broadly defined, is a package of performance monitoring software, data acquisition hardware, and communication systems that is used to collect, store, analyze, and display energy information. At a minimum, the EIS provides the whole-building energy-use information (Granderson 2009a). We define a ?dashboard? as a display and visualization tool that utilizes the EIS data and technology to provide critical information to users. This information can lead to actions resulting in energy savings, comfort improvements, efficient operations, and more. The tools to report analyzed information have existed in the information technology as business intelligence (Few 2006). The dashboard is distinguished from the EIS as a whole, which includes additional hardware and software components to collect and storage data, and analysis for resources and energy management (Granderson 2009b). EIS can be used for a variety of uses, including benchmarking, base-lining, anomaly detection, off-hours energy use evaluation, load shape optimization, energy rate analysis, retrofit and retro-commissioning savings (Granderson 2009a). The use of these EIS features depends on the specific users. For example, federal and other building managers may use anomaly detection to identify energy waste in a specific building, or to benchmark energy use in similar buildings to identify energy saving potential and reduce operational cost.

    Today, many procedures for assessing the indoor environment rely on both subjective and objective indicators (e.g. ANSI/ASHRAE 55-2004; ISO 10551). It is however unclear how these two types of measurements are related to perceived comfort. This article aims at assessing the relative utility of subjective (rating scale measures) and objective indicators of perceived comfort of indoor environments. In a hospital setting, physical environmental variables (e.g. temperature, relative humidity and noise level) were simultaneously measured as respondents (both patients and staff) rated their perception of the indoor environment. Regression analyses indicated that the subjective sensory ratings were significantly better than objective indicators at predicting overall rated indoor comfort. These results are discussed in relation to existing measurement procedures and standards. (author)

    In 2009, the ECRI Institute recommended warming cotton blankets in cabinets set at 130°F or less. However, there is limited research to support the use of this cabinet temperature. To measure skin temperatures and thermal comfort in healthy volunteers before and after application of blankets warmed in cabinets set at 130 and 200°F, respectively, and to determine the time-dependent cooling of cotton blankets after removal from warming cabinets set at the two temperatures. Prospective, comparative, descriptive. Participants (n = 20) received one or two blankets warmed in 130 or 200°F cabinets. First, skin temperatures were measured, and thermal comfort reports were obtained at fixed timed intervals. Second, blanket temperatures (n = 10) were measured at fixed intervals after removal from the cabinets. No skin temperatures approached levels reported in the literature that cause epidermal damage. Thermal comfort reports supported using blankets from the 200°F cabinet, and blankets lost heat quickly over time. We recommend warming cotton blankets in cabinets set at 200°F or less to improve thermal comfort without compromising patient safety. Copyright © 2013 American Society of PeriAnesthesia Nurses.

    This study investigated change of cognitions and feelings before, during, and after the process of procrastination. A questionnaire was administered to 358 undergraduate students asking them to recall and rate their experience of procrastinating. The results revealed that negative feelings which take place during procrastination interfere with task performance. Planning before procrastination is associated with positive feelings after procrastination, and these positive feelings assist task performance. Optimistic thinking is positively related to both positive and negative feelings; the former take place during procrastination, and the latter take place after procrastination.

    It is common to use activities of daily living (ADL) rating scales to identify the impact of health problems such as diseases, impaired eyesight or hearing on daily life. However, for various reasons people with health problems might feel hindered in daily life before limitations in ability to perform ADL have occurred. In addition, there is sparse knowledge of what makes people feel hindered by health problems in relation to their ADL capacity. The aim was to investigate feeling hindered by health problems among 1297 people aged 60-89 living at home in relation to ADL capacity, health problems, life satisfaction, self-esteem, and social and financial resources, using a self-reported questionnaire, including questions from Older Americans' Resources and Services schedule (OARS), Rosenberg's self-esteem and Life Satisfaction Index Z (LSIZ). People feeling greatly hindered by health problems rarely had anyone who could help when they needed support, had lower life satisfaction and self-esteem than those not feeling hindered. Feeling hindered by health problems appeared to take on a different meaning depending on ADL capacity, knowledge that seems essential to include when accomplishing health promotion and rehabilitation interventions, especially at the early stages of reduced ADL capacity.

    Full Text Available Objective: Analise feelings of women accompanying children in a paediatric intensive care unit Materials and Methods: Data were collected from August to October 2015 by the authors from individual interviews recorded with 15 women. The instrument was structured with the identification of qualitative variables, described in absolute and relative frequencies, and a guiding question. The "corpus" of each interview was electronically transcribed, floating readings were held and statements were categorized and analysed according Analise Content.  Results: 14 (93% are biological mothers; average age 30 years; 11 (73% have completed primary education; six (46% have an occupation or a profession. The four themes were inferred: ambivalence of feelings and coping were related to how individuals express and deal with the hospitalized patient’s situation; empathy with the health team and the structural condition of the critical environment can also generate feelings. Nursing diagnoses were formulated from the reported feelings. Conclusion: It was observed that the feelings identified could be originated by the health-illness hospitalization process as well as the structural components of the critical environment.

    Individuals exercise self-control daily to achieve desired goals; at the same time, people engage in social interaction daily and influence (feel powerful) or are influenced (feel powerless) by others. Does controlling the self have an unforeseen consequence for people's perception of their capacity to control others? Five studies-one correlational and four experimental-demonstrate that ego depletion from prior self-control determines one's personal sense of power; low-level, concrete mental construals account for this relationship. Our results showed that people with higher trait self-control reported a greater sense of power (Study 1). People who had depleted their self-control-related regulatory resources (vs. those who had not) experienced a lower sense of power (Study 2). The relationship between ego depletion and low sense of power was mediated by construal level (Study 3) and observed only when low-level, concrete construals were present, but not under high-level, abstract construals (Studies 4 and 5). © 2015 by the Society for Personality and Social Psychology, Inc.

    This paper examines factors associated with feeling suicidal in a large sample of urban men in Sydney and Melbourne, aged 18-50, including heterosexual, gay and bisexual men, HIV antibody positive and HIV antibody negative. As in previous research, sexuality (being homosexual or bisexual) was found to be a major predictor of suicidality. The research went some way towards explaining the close relationship between feeling suicidal and sexual orientation. Sexuality interacts with feeling bad in that, once men feel moderately bad/depressed, they are more likely to feel suicidal if they are homosexual or bisexual than if they are heterosexual. In addition, the research found that experience of verbal abuse and physical assault (harassment) increased feeling suicidal for both heterosexual and gay/bisexual men, not just for homosexual men as suggested by previous research, and that social isolation in the form of living alone is a further risk factor. Seeking counseling help and taking sexual risks were also independently associated with feeling suicidal. These actions may result from feeling suicidal rather than the reverse, and their association with feeling suicidal warrants further research. Many of the 46 independent variables examined in the research, including HIV antibody status and closeness to the HIV/ AIDS epidemic, were related to feeling suicidal only through their association with being gay/bisexual. Celibacy and general risk taking were not related to feeling suicidal in this study.

    2014-01-01

    The role of Ureaplasma spp. in human disease has been controversial, as these bacteria are commonly isolated as part of the normal genital tract flora. Ureaplasma has been shown to have a causal role in urogenital infections and is associated with significant foetal and neonatal morbidity and mortality when infection occurs during the perinatal period. Although rare, invasive Ureaplasma infection (meningitis, renal abscess, mediastinitis and arthritis) has also been reported in both adults and children. This review outlines the unique microbiological features and various clinical presentations of Ureaplasma infection. It also discusses the treatment options, which in the neonatal period can be particularly challenging. Copyright © 2013. Published by Elsevier Ltd.

  15. RAAAF's office landscape The End of Sitting: Energy expenditure and temporary comfort when working in non-sitting postures.

    Directory of Open Access Journals (Sweden)

    Simone R Caljouw

    Full Text Available An earlier study suggested that the activity-inviting office landscape called "The End of Sitting", designed by Rietveld Architecture Art Affordances (RAAAF, should be considered as an alternative working environment to prevent sedentary behavior. The End of Sitting lacks chairs and tables but consists instead of a myriad of sloped surfaces at different heights that afford workers to stand, lean or recline at different locations. In this study, we assessed the impact of four of its workspaces on physical intensity, temporary comfort and productivity of office work and compared the outcomes with sitting and standing behind a desk. Twenty-four participants worked for 10 minutes in each of the six test conditions. Energy expenditure, measured by indirect calorimetry, and heart rate were recorded. Questionnaires were used to assess the perceived comfort. The number of words found in the word search test was counted as a measure of productivity. The majority of The End of Sitting workspaces led to a significant increase in energy expenditure compared with sitting behind a desk (ps < .05. Average MET values ranged from 1.40 to 1.58 which is a modest rise in energy expenditure compared to sitting (1.32 METs and not significantly different from standing (1.47 METs. The scores on the general comfort scale indicated that some workspaces were less comfortable than sitting (ps < .05, but the vast majority of participants reported that at least one of The End of Sitting workspaces was equally or more comfortable than sitting. No differences in productivity between the test conditions were found. Further long-term studies are required to assess the behavioral adaptations, productivity and the level of comfort when using The End of Sitting as a permanent office.

    2015-07-01

    Individuals with the peculiar disturbance of 'overcompleteness' experience an intense desire to amputate one of their healthy limbs, describing a sense of disownership for it (Body Integrity Identity Disorder - BIID). This condition is similar to somatoparaphrenia, the acquired delusion that one's own limb belongs to someone else. In ten individuals with BIID, we measured skin conductance response to noxious stimuli, delivered to the accepted and non-accepted limb, touching the body part or simulating the contact (stimuli approach the body without contacting it), hypothesizing that these individuals have responses like somatoparaphrenic patients, who previously showed reduced pain anticipation, when the threat was directed to the disowned limb. We found reduced anticipatory response to stimuli approaching, but not contacting, the unwanted limb. Conversely, stimuli contacting the non-accepted body-part, induced stronger SCR than those contacting the healthy parts, suggesting that feeling of ownership is critically related to a proper processing of incoming threats.

    The bi-directional communication between limbic regions and the viscera play a central role in the generation and expression of emotional responses and associated emotional feelings. The response of different viscera to distinct, emotion-specific patterns of autonomic output is fed back to the brain, in particular to the cingulofrontal convergence region. Even though this process unfolds largely without conscious awareness, it plays an important role in emotional function and may influence rational decision making in the healthy individual. Alterations in this bi-directional process such as peripheral pathologies within the gut or alterations at the brain level may explain the close association between certain affective disorders and functional visceral syndromes.

    2015-12-01

    Full Text Available According to Sandro Nannini’s Time and Consciousness in Cognitive Naturalism, we can draw an analogy between the shift in the conception of time that occurred in physics with the introduction of relativity theory and a shift towards a scientifically more graspable functional concept of phenomenal consciousness. This analogy is meant to persuade us of the eliminative materialist view that we should abandon our folk psychological concept of consciousness. In my commentary, I examine the naturalization procedure underlying Nannini’s cognitive naturalism, argue for its inability to account for the phenomenal feel of conscious states, and point to some important differences between the conceptual change in the case of time and the intended change in the case of consciousness.

    Humla Province is a remote mountainous region of northwest Nepal. The climate is harsh and the local people are extremely poor. Most people endure a subsistence culture, living in traditional housing. Energy for cooking and heating comes from fuelwood, supplies of which are diminishing. In order to improve the indoor environment and reduce fuelwood use, smokeless stoves are being introduced to replace the open fire in Humli homes. There is some concern, however, that comfort levels may not be as acceptable with these stoves. The aim of this research was therefore to investigate ways in which the comfort levels in traditional Humli housing might be improved using simple and low cost strategies. Temperature data was recorded in four rooms of a traditional Humli home over a 12-day period and used with fuelwood data to validate a TRNSYS simulation model of the house. This model was then used to evaluate the impact on comfort levels in the house of various energy conservation strategies using PMV and PPD indicators. As a single strategy, it was found that reducing infiltration of outside air was likely to be more effective than increasing the insulation level in the ceilings. The most successful strategy, however, was the creation of sunspaces at the entrances to the living rooms. This strategy increased average internal temperatures by 1.7 and 2.3 C. In combination with increased insulation levels, the sunspaces reduced comfort dissatisfaction levels by over 50%. (author)

    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.

    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.

    This Research comes from the increasing quantity of shophouse in downtown Medan and the suburban area. The condition of shophouse tend to have narrowly spaced rooms, the middle area of the house are poorly lighted, and lots of space left unused. This research is supported by many spatial issues from previous studies. This study is conducted to determine the level of comfort of shophouse as a function of living space and focused on the spatial aspect namely anthropometry, indoor space circulation, space requirement and function, spatial design and indoor visual. This study uses the descriptive method with the qualitative and quantitative approach. Data collection technique is done by field observation, questionnaire method is also used to get the respondent perception of the spatial comfort of a shophouse. The result indicates that the level of spatial comfort of the shophouse is an uncomfort. So the improvements in the circulation of access to the building, spatial design, lighting, and aeration are needed to improve the spatial comfort of a shophouse.

    A goal of research on human perception and performance is to explore the relative importance of constraints shaping action selection. The present study concerned the relative importance of two constraints that have not been directly contrasted: (1) the tendency to grasp objects in ways that afford comfortable or easy-to-control final postures; and (2) the tendency to grasp objects with the dominant rather than the nondominant hand. We asked participants to reach out and grasp a horizontal rod whose left or right end was to be placed into a target after a 90° rotation. In one condition, we told participants which hand to use and let them choose an overhand or underhand initial grasp. In another condition, we told participants which grasp to use and let them choose either hand. Participants sacrificed hand preference to perform the task in a way that ensured a comfortable or easy to control thumb-up posture at the time of object placement, indicating that comfort trumped handedness. A second experiment confirmed that comfort was indeed higher for thumb-down postures than thumb-up postures. A third experiment confirmed that the choice data could be linked to objective performance differences. The results point to the importance of identifying constraint weightings for action selection and support an account of hand selection that ascribes hand preference to sensitivity to performance differences. The results do not support the hypothesis that hand preference simply reflects a bias to use the dominant hand.

    Increasing the amount of exterior air coming into a building, combined with a natural gas heating source has proven to be profitable. A study in a residence for handicapped people showed that doubling the amount of exterior air coming into the building actually improved the comfort level for the occupants while reducing the total electric energy bill by 21 per cent

    Exploration of the patient-therapist relationship (transference work) is considered a core active ingredient in dynamic psychotherapy. However, there are contradictory findings as for whom and under what circumstances these interventions are beneficial. This study investigates long-term effects of transference work in the context of patients' quality of object relations (QOR) and therapists' self-reported disengaged feelings. Therapists' disengaged feelings may negatively influence the therapeutic process, especially while working explicitly with the transference since discussing feelings that are present in the session is an essential aspect of transference work. One hundred outpatients seeking psychotherapy for depression, anxiety and personality disorders were randomly assigned to one year of dynamic psychotherapy with transference work or to the same type and duration of treatment, but without transference work. Patients' QOR-lifelong pattern was evaluated before treatment and therapists' feelings were assessed using the Feeling Word Checklist-58 after each session. Outcome was measured with self-reports and interviews at pre-treatment, mid-treatment, post-treatment, one year and three years after treatment termination. A significant interaction of treatment group (transference work versus no transference work) by QOR by disengaged therapist feelings was present, indicating that disengaged feelings, even small amounts, were associated with negative long-term effects of transference work, depending on QOR Scale scores. The strengths of the negative association increased significantly with lower levels of QOR. The negative association between even a small increase in disengaged therapist feelings and long-term effects of transference interpretation was substantial for patients with poor QOR, but small among patients with good QOR.

  2. Negotiating comfort in low energy housing: The politics of intermediation

    2015-01-01

    Optimising the energy performance of buildings is technically and economically challenging but it also has significant social implications. Maintaining comfortable indoor conditions while reducing energy consumption involves careful design, construction, and management of the built environment and its inhabitants. In this paper, we present findings from the study of a new low energy building for older people in Grenoble, France where conflicts emerged over the simultaneous pursuit of energy efficiency and comfort. The findings contribute to the contemporary literature on the sociotechnical study of buildings and energy use by focusing on intermediation, those activities that associate a technology to end users. Intermediation activities take many forms, and in some cases, can result in the harmonisation or alignment of energy efficiency goals and comfort goals. In other cases, intermediation is unsuccessful, leading to the conventional dichotomy between optimising technical performance and meeting occupant preferences. By highlighting the multiple ways that comfort and energy efficiency is negotiated, we conclude that buildings are provisional achievements that are constantly being intermediated. This suggests that building energy efficiency policies and programmes need to provide opportunities for intermediaries to negotiate the desires and preferences of the multiple stakeholders that are implicated in low energy buildings. -- Highlights: •Energy efficiency and comfort are two possibly contradictory aims of buildings. •We study the pursuit of these aims at the occupation stage of a new building. •Aligning these aims involve negotiating them with occupants. •Intermediation processes are key to such negotiations. •Intermediation processes involve both actors and technical devices

    Although several studies have reported that child physical abuse increased the risk for bullying involvement, the effect of current violence from adult family members (CVA) on bullying involvement and suicidal feelings among adolescents has not been sufficiently examined. This study investigated the association of CVA with adolescent bullying involvement and the interaction effect of CVA and bullying involvement on suicidal feelings. This cross-sectional study used data from a school-based survey with a general population of adolescents (grades 7 to 12). Data were collected using a self-report questionnaire completed by 17,530 students. Logistic regression analyses were performed to explore the association of CVA with adolescent bullying involvement and suicidal feelings. The overall response rate was 90.2%. The odds of students being characterized as bullies, victims, and bully-victims were higher among adolescents with CVA than without CVA (odds ratios (OR) = 2.9, 95% confidence interval (CI), [2.3–3.7], 4.6 [3.6–5.8], and 5.8 [4.4–7.6], respectively). Both CVA (OR = 3.4 [95% CI 2.7–4.3]) and bullying (bullies, victims, and bully-victims; OR = 2.0 [95% CI 1.6–2.6], 4.0 [3.1–5.1], 4.1 [3.0–5.6], respectively), were associated with increased odds of current suicidal feelings after adjusting for confounding factors. Furthermore, positive additive effects of CVA and all three types of bullying involvement on suicidal feelings were found. For example, bully-victims with CVA had about 19-fold higher odds of suicidal feelings compared with uninvolved adolescents without CVA. This study, although correlational, suggested that CVA avoidance might prevent bullying involvement and suicidal feelings in adolescents. PMID:27711150

    Full Text Available The aim of the research presented in this thesis is to design the characteristics of an Adaptive Thermal Comfort System for Dwellings to achieve a significantly better energy performance whilst not compromising the thermal comfort perception of the occupants. An Adaptive Thermal Comfort System is defined as the whole of passive and active comfort components of the dwelling that dynamically adapts its settings to varying user comfort demands and weather conditions (seasonal, diurnal and hourly depending on the aspects adapted, thus providing comfort only where, when and at the level needed by the user, to improve possibilities of harvesting the environmental energy (e.g. solar gain and outdoor air when available and storing it when abundant. In order to be able to create an Adaptive Thermal Comfort System to save energy knowledge is needed as to where, when, what kind and how much energy is needed to provide the thermal comfort. Therefore, this research aimed to gain insight in the dynamic behaviour of the weather and the occupant and the opportunities to design the characteristics of an Adaptive Thermal Comfort System for Dwellings to achieve a significantly better energy performance whilst not compromising the thermal comfort perception of the occupants answering the main research question;  What are the most efficient strategies for delivering thermal comfort in the residential sector with respect to better energy performances and an increasing demand for flexibility in use and comfort conditions? To answer the main research question three steps were taken, which also represent the three parts of the research: 1. The dynamic information of the factors influencing the thermal heat balance of the dwelling was gathered in order to determine their opportunities for adaptivity. A multidisciplinary approach to Thermal Comfort Systems is followed taking into account the dynamic of occupancy profiles, weather, building physics, HVAC and controls. A

    Full Text Available We report the discovery of WTS-2 b, a typical hot Jupiter in an unusually close 1.02-day orbit to a K-dwarf star. This is the second planet to be discovered in the infrared light curves of the WFCAM Transit Survey (WTS and is only one-and-a-half times the separation from its host star at which is would be destroyed by Roche lobe overflow. The predicted remaining lifetime of the planet is just 38 Myrs, assuming a tidal dissipation quality factor of Q'* = 106. The magnitude of Q'* is largely unconstrained by observations, thus WTS-2 b provides a useful calibration point for theories describing how frictional processes within a host star affect the tidal orbital evolution of its companion giant planets. It is expected that stars with large convective envelopes are more efficient at dissipating the orbital energy of the planet, and WTS-2 b provides an observational constraint in the sparsely populated K-dwarf regime. In addition, despite its relatively faint magnitude, the favourable size ratio of the WTS-2 star-planet system and the predicted hot equilibrium temperature of the planet will make it possible to characterise the planet's atmosphere via secondary eclipse measurements using existing ground-based instrumentation.

    Although bus comfort is a crucial indicator of service quality, existing studies tend to focus on passenger load and ignore in-vehicle time, which can also affect passengers' comfort perception. Therefore, by conducting surveys, this study examines passengers' comfort perception while accounting for both factors. Then, using the survey data, it performs a two-way analysis of variance and shows that both in-vehicle time and passenger load significantly affect passenger comfort. Then, a bus comfort model is proposed to evaluate comfort level, followed by a sensitivity analysis. The method introduced in this study has theoretical implications for bus operators attempting to improve bus service quality.

    2018-05-01

    Even without direct evidence of God's existence, about half of the world's population believes in God. Although previous research has found that people arrive at such beliefs intuitively instead of analytically, relatively little research has aimed to understand what experiences encourage or legitimate theistic belief systems. Using cross-cultural correlational and experimental methods, we investigated whether the experience of inspiration encourages a belief in God. Participants who dispositionally experience more inspiration, were randomly assigned to relive or have an inspirational experience, or reported such experiences to be more inspirational all showed stronger belief in God. These effects were specific to inspiration (instead of adjacent affective experiences) and a belief in God (instead of other empirically unverifiable claims). Being inspired by someone or something (but not inspired to do something) offers a spiritually transcendent experience that elevates belief in God, in part because it makes people feel connected to something beyond themselves.

    Given their significance to school violence, this study quantifies the association between bullying victimization and perceptions of safety separately for victimization where the type is not specified versus victimization that is physical in nature. Generalized liner mixed modeling was employed with 5,138 sixth- to eighth-grade students in 24 schools who self-reported on their bullying victimization and perceptions of school safety on an anonymous survey in fall 2015. Results indicate a multiplicative interaction exists with regard to the odds of feeling unsafe at school among those who were bullied at all (odds ratio [ OR] = 3.1) compared to those who were bullied physically ( OR = 9.12). For school nurses who work with students with a variety of concerns and health issues, this research indicates that the use of bullying victimization as an outcome, proxy and/or predictor, requires inquiry into the type of bullying experienced to aid in the care and support received.

    MAARBLE (Monitoring, Analyzing and Assessing Radiation Belt Loss and Energization) was an FP7- funded project, involving monitoring of the geospace environment through space and ground-based observations, in order to understand various aspects of the radiation belts (torus-shaped regions encircling the Earth, in which high-energy charged particles are trapped by the geomagnetic field), which have direct impact on human endeavors in space (spacecraft and astronauts exposure). Besides interesting science, the MAARBLE outreach team employed a variety of outreach techniques to provide the general public with simplified information concerning the scientific objectives of the project, its focus and its expected outcomes. An outstanding moment of the MAARBLE outreach experience was the organization of an international contest of musical compositions inspired by impressive sounds of space related to very low and ultra-low frequency (VLF/ULF) electromagnetic waves. The MAARBLE international contest of musical composition aspired to combine scientific and artistic ways of thinking, through the science of Astronomy and Space and the art of Music. It was an original idea to provide scientific information to the public, inviting people to "feel" the science and to think about art. The leading concept was to use the natural sounds of the Earth's magnetosphere in order to compose electroacoustic music. Composers from all European countries were invited to take part at the contest, using some (or all) of the sounds included in a database of magnetospheric sounds compiled by the MAARBLE outreach team. The results were astonishing: the contest was oversubscribed by a factor of 19 (in total 55 applications from 17 countries) and the musical pieces were of overall excellent quality, making the selection of winners a very difficult task. Ultimately, the selection committee concluded on the ten highest ranked compositions, which were uploaded on the MAARBLE website. Furthermore, the

    Many studies have reported energy savings after installing a dashboard, but dashboards provide neither individual feedback to the occupant nor the ability to report individual comfort. The Building Agent (BA) provides an interface to engage the occupant in a conversation with the building control system and the building engineer. Preliminary outcomes of the BA-enabled feedback loop are presented, and the effectiveness of the three display modes will be compared to other dashboard studies to baseline energy savings in future research.

    The emotion commonly labeled in English as being moved or touched is widely experienced but only tacitly defined, and has received little systematic attention. Based on a review of conceptualizations from various disciplines, we hypothesize that events appraised as an increase in interpersonal closeness, or as moral acts, when sufficiently intense, elicit a positive emotion typically labeled "being moved," and characterized by tears, goosebumps, and a feeling of warmth in the chest. We predicted this to be true for events a person participates in, as well as for events they observe. In Study 1, we elicited reports of recent episodes of weeping evoked by something positive, and also weeping because of something negative; we measured emotion terms, bodily sensations, and appraisals in a U.S. We discovered that events of positive tears, rather than negative tears, were associated with self-reported being moved or touched, with goosebumps, with feelings of chest warmth, and with the appraisals of increased closeness and moral acts. These appraisals mediated the difference in being moved between positive and negative events. We further found that appraisal patterns for personally experienced events were similar to the patterns for observed events. Finally, the 2 appraisals were more closely associated with being moved than with other emotion labels. This was corroborated in Study 2 in the U.S. and Norway, where we induced being moved, sadness, anxiety, and happiness through videos and measured these emotions, plus the appraisals and sensations from Study 1.

    2015-01-01

    The primary purpose of The Road to Self-Leadership Development: Busting Out of Your Comfort Zone is to provide individuals who want to become a leader with a systematic approach for learning how to first learn to become a self-leader. Organizations can use the book for identifying leader types and within leadership development training programs. Individuals need help in understanding the logic of being a self-leader and the critical role of self-worth (encompasses self-esteem, self-concept and self-confidence) in the process of developing the self-leader as a preparatory step to leadership development. The book offers two important benefits to readers. First, readers learn that to lead others involves learning how to lead the self and self-leadership is all about improving feelings of self-worth. Second, the book provides a practical model for readers to follow in creating a personalized self-leadership development process or an organizations human resource leaders with a model to follow in designing and impl...

    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.

    Full Text Available This study aimed at unveiling the feeling of hope in people who experience cancer in their existence. Qualitative study based on Heidegger’s phenomenology, performed with eight cancer patients assisted in a philanthropic organization, between December 2013 and February 2014, in a northwestern city in Paraná, Brazil, using the following guiding question: “How do you perceive the feeling of hope at this time in your life?” The analysis resulted in the ontological themes: searching for hope in dealing with cancer, and experiencing feelings of hope and despair in being with others. Patients revealed mixed feelings, going from the lack of hope at the time of diagnosis to a rekindling of hope, as well as those who never lost the will to live. We conclude that living with cancer causes extreme feelings; and hope emerges as a feeling capable of influencing and causes an expressive impact in coping with that.

    To determine whether provision of Reiki therapy during outpatient chemotherapy is associated with increased comfort and well-being. Double-blind, randomized clinical controlled trial. Outpatient chemotherapy center. 189 participants were randomized to actual Reiki, sham Reiki placebo, or standard care. Patients receiving chemotherapy were randomly placed into one of three groups. Patients received either standard care, a placebo, or an actual Reiki therapy treatment. A demographic tool and pre- and post-tests were given before and after chemotherapy infusion. Reiki therapy, sham Reiki placebo therapy, standard care, and self-reported levels of comfort and well-being pre- and postintervention. Although Reiki therapy was statistically significant in raising the comfort and well-being of patients post-therapy, the sham Reiki placebo also was statistically significant. Patients in the standard care group did not experience changes in comfort and well-being during their infusion session. The findings indicate that the presence of an RN providing one-on-one support during chemotherapy was influential in raising comfort and well-being levels, with or without an attempted healing energy field. An attempt by clinic nurses to provide more designated one-to-one presence and support for patients while receiving their chemotherapy infusions could increase patient comfort and well-being.

    Although there is extensive literature regarding sex differences in jealousy due to infidelity, guilt resulting from infidelity remains unexplored. We hypothesize that men will feel guiltier from imagined emotional rather than sexual infidelity, as it is most important for their partner's reproductive success. Similarly, we predict that women will feel more guilt from imagined sexual rather than emotional infidelity. The findings indicate a different pattern; men feel guiltier following sexua...

    Thermal comfort is central to energy consumption in housing and one of the main drivers behind worldwide GHG emissions. Research on residential energy consumption has therefore addressed comfort in relation to indoor temperatures. This paper argues that by widening the focus of comfort to include...... other aspects such as air, light and materials, more sustainable ideas of residential comfort might be developed. The paper takes a practice theoretical perspective but argues that the senses should be better incorporated into the approach to understand different aspects of comfort. The paper...... investigates how comfort can be understood as sensorial within theories of practice. This implies understanding how the senses are incorporated in embodied and routinised social practices, through which comfort is sensed and interpreted. Comfort is related to a range of everyday practices in the home...

    Human thermal comfort researches mainly focus on the relation between the environmental factors (e.g. ambient temperature, air humidity, and air velocity, etc.) and the thermal comfort sensation based on a large amount of subjective field investigations. Although some physiological factors, such as skin temperature and metabolism were used in many thermal comfort models,they are not enough to establish a perfect thermal comfort model. In this paper,another two physiological factors, i.e. heart rate variation (HRV) and electroencephalograph (EEG), are explored for the thermal comfort study. Experiments were performed to investigate how these physiological factors respond to the environmental temperatures, and what is the relationship between HRV and EEG and thermal comfort. The experimental results indicate that HRV and EEG may be related to thermal comfort, and they may be useful to understand the mechanism of thermal comfort.

    Sexual health is an important aspect of overall health. Barriers to taking an adequate patient sexual history exist. Few studies have explored medical learners' comfort, knowledge, and training surrounding taking sexual histories with lesbian, gay, bisexual, transgender, questioning/queer (LGBTQ) patients specifically. A 10-question survey was offered to medical students and resident/fellows at one US institution. Survey questions reflected participants' knowledge, comfort, and training related to sexual history taking with attention to LGBTQ care. A total of 159 surveys were returned (rate of 42%). A significantly lower level of comfort existed with taking sexual histories and managing sexual health issues in the LGBTQ segment of the patient population versus all patients, especially in the advanced training group. Participants recognized the importance of understanding their patients' overall sexual health, though medical students rated this as more important than the resident/fellow group did. A correlation existed between both comfort with taking sexual histories and discussing safe sexual practices and management of sexual issues, suggesting that further training would be helpful in this area. Twenty percent of the respondents reported receiving no training at all in eliciting sexual histories in LGBTQ patients. The most preferred format in this study for future training was interviewing standardized patients. Medical students and resident/fellows reported a significantly lower level of comfort with sexual history-taking and management of sexual issues in the LGBTQ population. A comprehensive training format that not only views sexual health as an integral part of overall patient health, but also integrates LGBTQ care, is needed in medical education.

    Full Text Available Kant’s critical theory on moral feeling can be divided into two stages: early and late. In the early stage, Kant was committed to accepting and transforming the traditional concept of moral feeling, while in the later stage he turned to developing his own unique theory on the topic. His beliefs about moral feeling changed between these two stages, both regarding the basic meaning of moral feeling (from intuitive empirical feelings to a priori feelings based on rationality and the function of moral feeling in moral philosophy (from the basis of moral law to the motivation of moral action. This paper argues that these shifts help clarify the framework of Kant’s moral philosophy and introduce a new dimension to Kant’s definition of feelings and the relationship between sensibility and intellectuality. Namely, sensibility is not only determined by intellectuality but also has its unique initiative. Through acting on the body, intellectuality generates intellectual feelings, which in turn assist humans in realizing their intellectual purpose as a limited rational being.

    This paper aims to explore the critical attributes of the concept feeling safe. The safe delivery of care is a high priority; however; it is not really known what it means to the patient to 'feel safe' during an inpatient hospitalization. This analysis explores the topic of safety from the patient's perspective. Concept analysis. The data bases of CINAHL, Medline, PsychInfo and Google Scholar for the years 1995-2012 were searched using the terms safe and feeling safe. The eight-step concept analysis method of Walker and Avant was used to analyse the concept of feeling safe. Uses and defining attributes, as well as identified antecedents, consequences and empirical referents, are presented. Case examples are provided to assist in the understanding of defining attributes. Feeling safe is defined as an emotional state where perceptions of care contribute to a sense of security and freedom from harm. Four attributes were identified: trust, cared for, presence and knowledge. Relationship, environment and suffering are the antecedents of feeling safe, while control, hope and relaxed or calm are the consequences. Empirical referents and early development of a theory of feeling safe are explored. This analysis begins the work of synthesizing qualitative research already completed around the concept of feeling safe by defining the key attributes of the concept. Support for the importance of developing patient-centred models of care and creating positive environments where patients receive high-quality care and feel safe is provided. © 2014 John Wiley & Sons Ltd.

    The MIT-Skywalker is a robotic device developed for the rehabilitation of gait and balance after a neurological injury. This device has been designed based on the concept of a passive walker and provides three distinct training modes: discrete movement, rhythmic movement, and balance training. In this paper, we present our efforts to evaluate the comfort of a bicycle/saddle seat design for the system's novel actuated body weight support device. We employed different bicycle and saddle seats and evaluated comfort using objective and subjective measures. Here we will summarize the results obtained from a study of fifteen healthy subjects and one stroke patient that led to the selection of a saddle seat design for the MIT-Skywalker.

    We propose an integrated and adaptable approach to improve patient care and clinical outcomes through analgesia and light sedation, initiated early during an episode of critical illness and as a priority of care. This strategy, which may be regarded as an evolution of the Pain, Agitation...... and Delirium guidelines, is conveyed in the mnemonic eCASH-early Comfort using Analgesia, minimal Sedatives and maximal Humane care. eCASH aims to establish optimal patient comfort with minimal sedation as the default presumption for intensive care unit (ICU) patients in the absence of recognised medical...... requirements for deeper sedation. Effective pain relief is the first priority for implementation of eCASH: we advocate flexible multimodal analgesia designed to minimise use of opioids. Sedation is secondary to pain relief and where possible should be based on agents that can be titrated to a prespecified...

    The quality of natural light, the landscape surrounds and the techniques of construction are important factors in the selection of architectural colors. Observation of exterior walls in differentiated climates allows the recognition of particularities in the use of color which satisfy the need for visual comfort. At a distance of 2000 kilometers along the coast of Peru, Lima and Mancora at 12° and 4° respectively, are well defined for their climatic characteristics: in Mancora sunlight causes high reflection, in Lima overcast sky and high humidity cause glare. The study of building color effects at these locations serves to illustrate that color values may be controlled in order to achieve visual comfort and contribute to color identity.

    Given the importance of buildings on the energy balance in Greece, an attempt has been made to study their energy behaviour and thermal comfort. Our primary purpose is to provide an estimation of the building's energy consumption and examine how this affects the comfort conditions. This includes the definition of thermal conditions acceptable for various activities at different times of day during each month of the year. We cannot underestimate the value of real measurements and observations of the building's energy systems, but such data are not always available. The best opportunities for improving energy performance occur early in the design process. Our simulation results can give an indication on which end uses are the most energy consuming, the 'weaknesses' of a building and thus urge the owner or engineer to take effective conservation energy measures

Using the concept of illness trajectory we analyse how the ambulance crews balance machine work, which involves continuously...... monitoring the equipment, comfort work, which is actions taken to relieve the pain or discomfort of the patient, and sentimental work, which is care for the patient’s physical and mental well-being, often verbal in nature. The analysis shows that comfort and sentimental work often takes priority over machine...... work, but also that this has negative consequences. Equipment for use in ambulances should aim at supporting the ambulance crews in competently and dynamically balancing the different types of work and should, consequently, avoid binding the crew’s attention for unbroken periods of time....

    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.

  16. Development of Light Powered Sensor Networks for Thermal Comfort Measurement

    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.

  18. Beyond the classic thermoneutral zone: Including thermal comfort.

    The thermoneutral zone is defined as the range of ambient temperatures where the body can maintain its core temperature solely through regulating dry heat loss, i.e., skin blood flow. A living body can only maintain its core temperature when heat production and heat loss are balanced. That means that heat transport from body core to skin must equal heat transport from skin to the environment. This study focuses on what combinations of core and skin temperature satisfy the biophysical requirements of being in the thermoneutral zone for humans. Moreover, consequences are considered of changes in insulation and adding restrictions such as thermal comfort (i.e. driver for thermal behavior). A biophysical model was developed that calculates heat transport within a body, taking into account metabolic heat production, tissue insulation, and heat distribution by blood flow and equates that to heat loss to the environment, considering skin temperature, ambient temperature and other physical parameters. The biophysical analysis shows that the steady-state ambient temperature range associated with the thermoneutral zone does not guarantee that the body is in thermal balance at basal metabolic rate per se. Instead, depending on the combination of core temperature, mean skin temperature and ambient temperature, the body may require significant increases in heat production or heat loss to maintain stable core temperature. Therefore, the definition of the thermoneutral zone might need to be reformulated. Furthermore, after adding restrictions on skin temperature for thermal comfort, the ambient temperature range associated with thermal comfort is smaller than the thermoneutral zone. This, assuming animals seek thermal comfort, suggests that thermal behavior may be initiated already before the boundaries of the thermoneutral zone are reached.
