  • In this study, the fugitive emission characteristics of airborne volatile organic compounds from different source categories were evaluated with respect to the concentrations measured in the vicinity of the sources. A total of 22 different sources were investigated, including gasoline storage and filling stations, painting spray booth, laundry, printing officer, textile industries, and a number of environmental sanitary facilities such as landfill, wastewater treatment and incineration plants. The target VOCs included 83 individual compounds, which were determined by adsorption sampling and thermal desorption coupled with GC/MS analysis. Overall, the aliphatic compounds appeared to be the most abundant class of compounds in terms of their concentrations, followed by aromatic, and halogenated hydrocarbons. As a single compound, however, toluene was the most abundant one, explaining 11% of the total VOC concentrations as an average of all the dataset. Among source categories, petroleum associated sources such as gasoline storage/filling stations, and laundry factory were identified as the most significant sources of aliphatic hydrocarbons, while aromatic VOCs were dominantly emitted from the sources handling organic solvents, such as painting booth, printing offices, and textile dyeing processes. However. there was no apparent pattern in terms of the contributions of eath group to the total VOCs concentrations in environmental sanitary facilities. It was also found that the activated carbon adsorption tower installed for the VOC emission control in some facilities do not show any effective performances, which may result in the increased VOC levels in the ambient atmosphere.

  • In this study 1, the dyeability and sun protection characteristic of the fabrics dyed with pine needles extract was investigated. In the test of color difference, the surface color of all the dyed fabric of both cotton and silk came to light as greenish yellow. In the test of dyeing colorfastness, the colorfastness to sunlight of dyed cotton fabric was below 2nd grade and the one of dyed silk fabric was below 3rd grade. The colorfastness to laundry for the degree of discoloration showed a difference as to mordants, but the colorfastness to laundry for the degree of contamination was excellent as all the dyed fabrics were 4th-5th grade. The colorfastness to perspiration was excellent as the degree of discoloration was more than 3rd grade and the degree of contamination was more than 4th-5th grade. The colorfastness to rubbing showed the excellent result as all the dyed fabrics were 4th-5th grade. In the test of sun protection factor(SPF), the cotton and silk fabrics dyed with $FeSO_4{\cdot}7H_{2}O$ mordant showed very high sun protection characteristic as the SPF was each 36.1 and 42.5. In the test of sun protection rate for UV-A and UV-B, the cotton and silk fabrics dyed with $FeSO_4{\cdot}7H_{2}O$ mordant showed the very high sun protection rate of more than $90\%$.

  • In Korean apartment housing, balcony is semi-outdoor space for storage and drying laundry. Recently, this semi-outdoor balcony space has been merged into indoor living space with the legal permission of balcony extension. It results in disappearance of the original function of balcony in apartment housing. This study attempts to propose better utilization of balcony extension by analyzing how balcony has been extended and used, and what residents' needs are. This study asks 400 housewives living in apartment housing in Jangyu new urban area, Kyungnam. Findings are : 1) Balcony extensions are carried out in a living room, a large bedroom and a small bedroom. Most extensions are made for enlarging adjacent indoor living space; 2) Original balcony that is not extended is used for drying laundry, resting, flower pot, storing, and kid's playing; 3) The residents recognize that problems of balcony extension are the decreased heating efficiency, the reduced soundproofing effect, the loss of spare housework space, and the disappearance of buffer between indoor and outdoor space; 4) Many residents want to extend their balcony space of a small bedroom and a large bedroom and to keep the balcony space of a kitchen-dining room and a master bedroom as they are.
