Effects of clothing values on perceived clothing deprivation among adolescents.

The present purpose was to investigate the relationship between clothing values and perceived clothing deprivation among adolescents. From previous studies a questionnaire was developed to measure perceived clothing deprivation (the dependent variable) and clothing values (the independent variable). Items were measured on a 5-point Likert scale. The sample was comprised of 338 high school students enrolled in Grades 9 to 12 home economics courses at six high schools. The effects of values (aesthetic, economic, exploratory, political, religious, sensory, social, and theoretical) on perceived clothing deprivation were tested. Pearson correlations and multiple regression indicated positive relationships between perceived clothing deprivation and the economic and social clothing values. Also, these values accounted for significant proportions of the variance of perceived clothing deprivation. Negative relationships between aesthetic and political clothing values and perceived clothing deprivation were noted; however, they did not contribute significantly to the variance of perceived clothing deprivation. No relationships were found between the remaining clothing values and perceived clothing deprivation.

Aortic valve replacement: a ten-year follow-up of non-cloth-covered vs cloth-covered caged-ball prostheses.

From 1965 to 1976, 721 isolated aortic valve replacements were performed at the University of Oregon hospitals, utilizing Starr-Edwards caged-ball prostheses. Three models of aortic prostheses were introduced during this period: a non-cloth-covered model has been in continuous use since 1965; a cloth-covered model was begun in 1968 and has been supplanted by the modified composite-strut or "track" model since 1972. The 5-year actuarial survival rate for operative survivors is about 80% for both non-cloth-covered and cloth-covered valves, while the 10-year survival is 61%, based on the older model only. The actuarially-determined percentages of patients experiencing significant thromboembolic episodes (i.e., all except transient ischemic episodes) at 5 years are 7% for the cloth-covered and 9% for the non-cloth-covered model. If transient ischemic attacks are included, the cloth-covered model has only an 8% incidence at 5 years compared to a 22% incidence for the older model. However, the cloth-covered valves are subject to a higher risk of reoperation because of the possibility of cloth injury. The "track" valve, therefore, was designed with exposed metal on the inner surface of each strut to prevent ball-cloth contact. In 107 patients (mean follow-up period 1 year) receiving anticoagulation, this prosthesis has maintained the same low incidence of thromboembolism as the previous cloth-covered model, with no reoperations for valve failure.

Clothing and exercise. II. Influence of clothing during exercise/work in environmental extremes.

Thermoregulatory studies often investigate thermal responses without considering the influences of clothing. These studies have expanded our understanding of basic human responses to various environmental conditions. However, human thermoregulation is variable and modified by heat transfer interactions between skin surface area, clothing and environment. Much of the original work on the influence of clothing on work performance was the result of ergonomic concerns. Currently, the importance of clothing and the influence of new clothing technology aimed at minimising thermal stress has spawned a new interest. For hot climates, new fabrics have been developed with improved wicking properties to keep the wearer cooler and drier, and to enhance heat transfer from the body while providing greater comfort. In contrast, the challenge of cold environments requires a different approach to clothing, which tries to minimise the free movement of air and water along the skin surface of the body. The materials used should also be able to absorb radiant heat from the environment and be nonconductive. In a cold climate, the wearer needs to balance the need for a clothing barrier for warmth with the potential for accumulating too much heat as the result of metabolic heat production from exercise. To counteract this potential problem, it is suggested that cold-weather clothing be worn in layers that can be removed during exercise and replaced during less active periods. Protective clothing for firefighters, hazardous waste workers and astronauts, and athletic protective gear, have specialised design requirements which may be influenced by considerations, for example, of environmental conditions, garment weight, the need for durability, impact forces.

Complications due to cloth wear in cloth-covered Starr-Edwards aortic and mitral valve prostheses--and their management.

Five cases of complications due to cloth wear in cloth-covered composite-seat Starr-Edwards aortic and mitral valvular prostheses are described. The complications of cloth wear were recurrent systemic emboli in three patients, two with aortic and one with mitral prosthesis, and severe hemolytic anemia in two patients with aortic prosthesis. The over-all incidence of clinically significant complications due to cloth wear in aortic and mitral valve prosthesis was 2.5 per cent. The diagnosis of cloth wear is impossible before reoperation and it was made by exclusion of other causes of recurrent transient cerebral ischemic attacks or systemic emboli and by exclusion of other causes of hemolytic anemia. Clinical and laboratory findings suggestive of cloth wear are described. Aggressive management of complications of cloth wear by reoperation is likely to prevent disabling or lethal consequences. Porcine xenograft aortic and mitral bioprostheses were used in these patients to replace the cloth-covered valvular prostheses. The symptoms due to cloth wear were abolished in all patients by reoperation, and all patients are off anticoagulants postoperatively. The operative mortality rate for reoperation in this small group of patients was zero.

Individualized adaptation of clothes for impaired persons. A comparison of two groups with and without experience of adapted clothes.

Impaired persons often have difficulties in obtaining suitable clothing. Questionnaires on this subject were sent to a consecutive series of impaired persons. Group 1 (n = 50) had received adapted clothes and group 2 (n = 81) had not. Questionnaire A (both groups) contained general questions on clothes and questionnaire B (Group 1) contained questions on adapted clothes. The result of the study shows a significant difference (p less than 0.01) between the need for adapted clothing in group 1 and group 2. No significant difference was found between the groups regarding the reason for obtaining and using adapted clothes. It was difficult for 94% in group 1 and 85% in group 2 to obtain clothes which were suitable for the individual's impairment and which made their daily activities easier. In group 1 the adapted garments were of most value when dressing and undressing (86%). They also reduced the time needed, by 31% for the individual, by 43% for a helper; and by 62% when going to the toilet. The adapted garments were considered smarter and more comfortable by 64%. Eighteen per cent considered that wearing them had increased their self-confidence.

Clothing surface area as related to body volume and clothing microenvironment volume.

The evaluation of clothing surface area becomes important in analyses of heat exchange between the clothed body and its environment. The evidence accumulated in the studies of radiation area has led to the conclusion that the ratio of clothing surface area to body surface area (fcl) may be defined as a function of clothing insulation. However, the effects of clothing fit have been disregarded. Radiation area factors (Ar/AD) were derived from pictures of five subjects wearing four different helicopter pilot suits. While sitting on a seat suspended in the center of a box-shaped frame, photographs were taken of the subjects with a fish-eye lens at 90 equidistant points on the six sides of the frame. The derived Ar/AD of 0.7 +/- 0.18 for the unclothed subjects closely agreed with that reported by Fanger, while it scattered in a relatively wide range for a given suit. The present study proposes a new approach for predicting fcl as related to body volume and the clothing microenvironment volume. The predictions show a good correlation with the values derived from the photographs. It is, therefore, suggested that improvement in the prediction of fcl has been achieved by incorporating clothing fit.

Studies on water vapor pressure gradient from external air through clothing to the skin in relation to external humidity and clothing conditions.

Using a hygrometric capsule method developed by the authors, water vapor pressure was measured at each layer of clothing as well as at the skin surface on a human subject under actual wearing conditions. The pattern of vapor pressure gradient from the skin surface through clothing to the external air was examined in relation to the ambient vapor pressure and ths sort of textiles worn. The following findings were obtained. 1) Water vapor pressure gradient was greater between coat and external air than that between coat and underwear. The gradient became steeper again between underwear and the skin. 2) Under given clothing conditions, vapor pressure at each layer of clothing as well as at the skin varied according to the ambient humidity. However, the pattern of vapor pressure gradient from the skin through clothing to the external air was not greatly influenced by the external humidity. 3) The pattern of vapor pressure gradient from the skin through clothing to the external air was not greatly influenced by the external humidity. 3) The pattern of vapor pressure gradient through the clothing as a whole differed according to the kinds of textiles used for coat and underwear.

The effects of two kinds of mask (with or without exhaust valve) on clothing microclimates inside the mask in participants wearing protective clothing for spraying pesticides.

AIM: The study aimed at discovering the effects of wearing two types of protective mask on the clothing microclimate (temperature, humidity) inside the mask, physiological parameters and subjective sensations. METHOD: Five healthy female students performed intermittent step exercise while wearing the protective clothing in a climate chamber at 28 degrees C and 60% relative humidity (RH). One mask was made of non-woven fabric and had no exhaust valve (mask A), and the other had an exhaust valve (mask B). RESULTS: (1) Clothing microclimate temperature inside the mask was significantly lower in mask B than in mask A. The final values were 35.5 +/- 0.3 degrees C in mask A and 34.6 +/- 0.8 degrees C in mask B. (2) Clothing microclimate humidity inside the mask was significantly lower in mask B than in mask A. The final values were 37.9 +/- 0.9 g/m3 in mask A and 35.7 +/- 2.0 g/m3 in mask B. (3) Cheek skin temperature inside the mask was kept significantly lower in mask B than in mask A. (4) Clothing microclimate humidity at trunk level increased more slowly with mask B than with mask A for four participants. (5) Rectal temperature increased more slowly with mask B than with mask A for three participants. (6) Tympanic temperature increased more slowly with mask B than with mask A for two out of four participants. DISCUSSION: We discussed these findings from the viewpoint that the dry and wet heat loss was accelerated through the nose under the influence of a reduced level of clothing microclimate inside mask B, having probably helped selective brain cooling by cooling more effectively the vein circulating blood through the nose.

Attempts to control clothes-borne infection in a burn unit. I. Experimental investigations of some clothes for barrier nursing.

Clothes-borne transmission is an important way of spread of infection from patient to patient which is not interrupted by common cotton gowns. New barrier garments were designed from spun-bonded olefin that, in particle penetration tests, was 100 times better as a filter than cotton cloth. Three designs, a gown, a loose coverall and a close overall, were compared with each other and with conventional cotton gowns in experimental exercise and nursing procedures. Staphylococcus aureus from burned patients were used as markers. The close coverall was 4-7 times better than the loose coverall or gown in preventing the soiling of clothes worn underneath it, but appeared to permit substantially more transfer from garments underneath it to a mock 'patient' and to the air than did the looser garments. A cotton gown reduced the soiling of clothes underneath it by more than 10 times and the contamination of a mock patient by more than 30 times as compared with no barrier garment. The close coverall further diminished the contamination of clothes but not the transfer to the patient. The possible mechanisms for the discrepancy between particle transmission tests annd experimental porcedures are discussed.

Clothing and exercise. I: Biophysics of heat transfer between the individual, clothing and environment.

Despite large environmental variations, the human body maintains a tightly regulated core temperature. Effective thermoregulation must balance the interaction between skin surface, clothing and ambient air. Indices of thermal stress (wet bulb globe temperature, heat stress index, maximum evaporation rate, required evaporative rate and wind chill) provide valuable information concerning the heat exchange between the individual and the environment, and serve as protective guidelines while working in environmental extremes. The role of clothing, as an interactive barrier, greatly affects thermal balance. Clothing is varied according to prevailing environmental conditions, metabolic heat production, gender and age differences, fabric thermal properties, garment design and intended use. Models (static, dynamic and human) have investigated the biophysical transfer of heat between the skin surface area, clothing and ambient air. Additionally, the role of metabolic heat production during exercise can greatly influence tolerance to thermal stress during a variety of environmental conditions.

Clothing adaptations: the occupational therapist and the clothing designer collaborate.

An occupational therapist and a clothing designer collaborated in solving the dressing problem of a child with multiple amputations. The dressing problems were identified and solutions for clothing adaptations relating to sleeves, closures, fasteners, fit, and design were incorporated into two test garments. Evaluation of the garments was based on ease in dressing and undressing, the effect on movement and mobility, the construction techniques, and their appearance. A description is given of the pattern adjustments, and considerations for clothing adaptations or selection or both are discussed. These clothing adaptations can be generalized to a wider population of handicapped persons.

Attempts to control clothes-borne infection in a burn unit, 2. Clothing routines in clinical use and the epidemiology of cross-colonization.

Previous investigations have shown that cross-contamination in a burn unit is mainly clothes-borne. New barrier garments have been designed and tried experimentally. The aim of the present study was to investigate the effects of different clothing routines on cross-contamination. In a long-term study, the rates and routes of colonizations with Staphylococcus aureus, Streptococcus groups A, B, C, F, and G and Pseudomonas aeruginosa were examined. The exogenous colonization rates were, with S. aureus 77%, with Streptococcus species 52% and with Ps. aeruginosa 32%. The colonization rate with Ps. aeruginosa was higher in patients with larger burns. Patients dispersed Streptococcus and Ps. aeruginosa as well as S. aureus into the air of their rooms in considerable amounts, but dispersers were not more important as sources of cross-colonization than non-dispersers. In comparison of clothing routines, there was no difference in overall colonization rates. The newly designed barrier garment that was made from apparently particle-tight material did not reduce the transfer of bacteria from patient to patient. A less rigid routine than that previously used did not increase the risk of cross-contamination. A thorough change of barrier dress after close contact nursing delayed the first exogenous S. aureus colonization from day 6 to day 14 after admission. This routine might be recommended for clinical use. Otherwise, methods must be developed for adequate selection of materials intended for barrier garments.

Technical note. Comparison between estimated worn clothing insulation and required calculated clothing insulation in moderately cold environments (0 degree C < or = ta < or = +15 degrees C).

Six female and 33 male workers of the food industry (16-55 years), divided into three groups according to climatic conditions at the workplaces, were monitored during a typical shift. Fourteen subjects worked continuously in 0-7 degrees C, 18 in 13-15 degrees C and seven moved frequently between these climatic areas. Mean metabolic rates, heart rates, rectal temperatures and skin temperatures at the trunk and at the feet were similar between each of the three groups. Considerable differences between estimated clothing insulations worn and calculated required clothing insulations (IREQneutral) were statistically analyzed. The results suggest that--apart from a limited overestimation--this discrepancy is mainly related to the difference between time-adjusted averages of metabolic rates of the single activities and the respective daily minimum suggesting the need for an adequate weighting for the metabolic rates, particularly if workers are at least temporarily exposed to air temperatures of more than 7-13 degrees C.

Thermal function of a clothing ensemble during work: dependency on inner clothing layer fit.

A tight-fitting crewneck undergarment (U) and a loose-fitting shirt (S) were studied as part of a commonly used clothing ensemble (Itot = 0.22 m2 K W-1). Ten clothed male subjects performed standardized packing work (VO2 = 0.761 min-1) at three climatic conditions, 20 degrees C and Va = 0.45 m s-1 (0-30 min), at 5 degrees C and Va = 0.39 m s-1 (30-60 min) and at 5 degrees C and Va = 1.23 m s-1 (76-90 min). From 60-75 min the subjects rested at 20 degrees C. The physiological and subjective responses varied with the environment from slightly warm to cool. U resulted in warmer responses than S: torso and upper arm skin temperatures were higher at both 5 degrees C and 20 degrees C, evaporation rate was higher at 20 degrees C, mean skin temperature was higher during work at 20 degrees C, sweating tended to begin earlier and skin wettedness to be higher with U than with S. No differences were observed in core temperature, heart rates, and subjective thermal evaluations. It was concluded that a tight-fitting inner layer (U) compared to a loose-fitting one (S) allows for less cooling of the skin in both a cool and a slightly warm environment.

Patient clothing. The problems of providing a personal clothing service.

Allowing patients or clients in hospital to wear their own clothes is a fundamental part of good nursing care, yet it has not become universal practice, despite being laid down as policy by the Department of Health in 1972. This paper describes one ward's experience of trying to set up a personalised laundry scheme, and the obstacles encountered.
