  • The influences of luminous environment on visual responses and fatigue sensation in art galleries were examined in this study. Field measurements and survey were performed in three galleries under various illuminance and luminous conditions. Result implies that vertical illuminance on art paintings needed to be somewhere between 200 lx and 300 lx to avoid visual discomfort. The vertical illuminance difference between consecutive paintings should not exceed 100 lx to keep visually comfortable environment. Visual comfort sensations were related to glare, visual stimulus, reflection from paintings, illuminance variation, and the sensation that subjects can clearly see the paintings. The sensation of fatigue was significantly influenced by the changes of luminous element that caused visual stimulus and discomfort. The sensation of eye fatigue among physical fatigue was primarily influenced by the glare, visual stimulus and comfort. The psychological fatigue was also influenced by eye fatigue, visual comfort, brightness and satisfaction with color of light.

  • This study has been purposed to provide thermal comfort range in accordance with the residential style of radiant floor heating space, and to compare it with the thermal comfort range at predicted mean vote. The survey for the thermal sensation vote to the subjects and the measurement of environmental factors has been executed, and regression analysis has been performed. It is interpreted that the combination of the physical factor and the psychological factor results lower neutral point of the floor sitting style than that of the chair sitting style. There are some difference between the measured predicted mean vote and the thermal sensation vote via survey, which appears to be caused by distinctive heat transfer characteristic of floor radiant heating space, such as, high radiant temperature and contact thermal sensation of floor surface.

  • The purpose of this study was to reveal the thermal comfort and physiological and psychological effects of spending time in broad-leaved forests in suumer. Thirty-one university students (with an average age of 21.4 ± 2.1 years) participated in the study, and a within-subjects experimental design methodology was used. The participants moved to an experimental site (with a crown closure of 76.6%) or a control site (25.9%), sat on a chair to eliminate the impact of movement, and rested for 5 minutes with closed eyes. At this time, thermal comfort, heart rate variability, heart rate, and forehead temperature were continuously measured. After that, blood pressure and pulse rate were measured, and a subjective evaluation was conducted. As a result, spending time at an experimental site showed a statistically significant decrease in the predicted mean vote and the percentage of dissatisfied values, enhancement of parasympathetic nerve activity, decrease of forehead temperature, diastolic blood pressure, heart rate, pulse rate, and improvement of personal thermal sensation (thermal sensation vote and comfort sensation vote). In conclusion, it was found that a forest with high crown closure reduces thermal stress and induces physiological and psychological relaxation.

  • The purpose of this study is to investigate the environmental factors relating to children's outdoor play and to assess how the residential neighborhood is suitable for play in the perception of parents. Based on a citywide survey of 500 parents of elementary school students in grades 1-4 in Seoul, this empirical study shows that children's outdoor play environments in residential neighborhoods of Seoul have been observed to be overall unsuitable for play activity. Three physical environmental factors (spatial availability, neighborhood attractiveness, and street difficulties) and three social environmental factors (fear of crime, social interactions, and psychological comfort) are related to children's play activity. Five factors, with the exception of the psychological comfort factor, impact the suitability of children's outdoor play environment. Specifically, it is the physical environment, rather than the social environment, that was deemed unsuitable in spite of its impacts. These findings help us understand the current conditions of neighborhood play environments associated with children's play activity. It is necessary to improve parents' perceptions of the play environment and children's play activities by improving the physical environment.

Method: Data collection from 9 participants with elderly institutionalized dementia with approval from directors of the institute was done by in depth interviews during a seven month period from May, 2003 to December, 2003. Data analysis was done by repeated reading of the transcribed interviews, and 344 concepts and 39 subcategories were generated. Results: Family members of the dementia elderly experienced various degrees of exhaustion, physically, mentally, and socially. The degree of their exhaustion was related to the severity of the family member's symptoms, and length of the dementia. Coping strategies were effected by economic status, social support from blood related families or neighbors, depth of their relationship with elderly institutionalized dementia. They were even affected by the elderly family members institutionalization. Conclusion: After institutionalization participants felt some guilt from not assuming their responsibilities as children. On the other hand they regained privacy, freedom, security, and comfort, so that their life returned to normal. They even felt more comfort because their elderly were living in a safer environment, and received a better quality of care. Participants had better composure, so that they could even take care of neighbors in need. They hope that there is more governmental involvement in terms of subsidy and numbers of institutes. Findings of the study will be a ground for the development of a coping program for families with elderly institutionalized dementia. Further studies are recommended to explore types of family, and to develop programs for the families to help them interact with each other.

  • The purpose of this study is to investigate the satisfaction of the adolescents' school backpack bag and the important criteria when purchasing for developing comfort and functional backpack. The questionnaire was composed and surveyed with 245 middle school students and the data were analyzed through SPSS 13.0. Purchasing criteria were grouped into 5: practical, shop environment, comfort, aesthetic and maintenance. Satisfaction factors were function/comfort, fashion/aesthetic and durability/A.S. 50.2% of students recognized the inappropriate wearing backpack might cause the deformation of body shape. And the wrong habit of wearing bag was found to affect the body posture of students. Main symptoms caused by wearing it for long time are ‘sweating around shoulder and back' and ‘feeling stiff in shoulders and waist'. Needs arise to develop the bag which could prevent them and to educate students how to wear bags. According to the result from MDS of purchasing criteria, one axis is product vs. environment, and other is functional vs. psychological aspects. According to the result from MDS of bag satisfaction, one axis is function/durability vs. fashion/appearance, and other is gestalt quality vs. part quality. They wanted the improvement in the aspects of shape/design, material, maintenance, comfort and usability of the bags. Specially it is required that we research the adolescent customer-oriented way and develop the new materials or shapes pursuing both shoulder comfort and characteristics.
