A person's residence is the primary environment which affects physical and emotional-gratification. Residential environments are very important to a person's quality of life. Because the age of society has rapidly increased, we must take a profound interest in the welfare and residences of the aged. While the government has begun to prepare for an aging society, the residential environments of the aged has not been fully considered. Because the welfare of the aged begins in the house, the term 'residence for the aged' is not limited to the physical space. Because residences for the old aged are included in various social policies such as family relations, social security, health care, safety etc, relevant policies for these residences must be prepared as rapidly as possible. This study-focused on both the importance of residences for the aged and the residential desires of the aged, and aims to propose planning criteria for the residences of the aged.

A biofilter study was performed in order to remove mixed benzene and ethylene emitted from soil and groundwater remediation. In particular, more than 96% of ethylene was removed at residence times of 10～15 min, and the possibility of use of the biofilter was obtained. The benzene removal efficiency was achieved as much as 100% at residence times of 2～15 min. With a residence time of 15 min, the maximum elimination capacity of benzene and ethylene was 4.3 g/$\textrm{m}^3$hr and 1.4 g/$\textrm{m}^3$hr, respectively. The maximum elimination capacity of benzene was 3 times higher than that of ethylene. Carbon dioxide concentration decreased as residence times were lowered due to low ethylene degradation rate. The maximum carbon dioxide production rate of 3,169 [mg-$CO_2$/(g-${C_2}{H_4}$＋${C_6}{H_6$)] was investigated when benzene and ethylene were completely removed. It was found that dominant bacteria in the benzene-degrading microorganisms were identified as Bacillus mycoides and Pseudomonas fluorescens. Dominant bacteria in the ethylene-degrading microorganisms were identified as Pseudomonas putida and Pseudomonas fluorescens.

The study is about variations in Carbonyl compounds concentration within apartment buildings according to pre-residence and residence. We consecutively investigated indoor air pollutants in 120 households in 6 cities at pre-residence and residence. Carbonyl compounds were collected using the 2,4-DNPH cartridge and were analyzed using HPLC. The carbonyls concentration of indoor air in the new apartments before occupation measured formadlehyde($76.0\;{\mu}g/m^3$), acetone($85.9\;{\mu}g/m^3$), acetaldehyde($13.8\;{\mu}g/m^3$). The carbonyls concentration of indoor air in the new apartments after occupation measured formadlehyde($233.1\;{\mu}g/m^3$), acetone($128.9\;{\mu}g/m^3$), acetaldehyde($29.8\;{\mu}g/m^3$), respectively. As a result, the mean concentration of carbonyl compounds within the pre-occupancy stage was lower than those of residence.

The purpose of this study is to develop an evaluation system for integrative comfort values of Hanok residence. For this study, a mock-up located in Yongin, Gyeonggi province built by an ongoing governmental research project has been chosen. Then, SSN (Smart Sensor Network) has been utilized for monitoring quantitative factors in the environment and detailed face-to-face surveys have been performed for analyzing qualitative comfort indexes from residents in the experimental settings. Then, this study employs a combined evaluation system using AHP (Analytic Hierarchy Process) established for estimating overall DIC (Degree of Integrative Comfort) of the Hanok residence. As a result, the evaluation system could verify the total comfort indexes of Hanok residence and suggest converged methodologies for establishing value assessment system for traditional residential facilities. The method of DIC suggested in this paper would be examined with current residents in a built mock-up to see its applicability as a comprehensive evaluation model, and it is expected that collected year-round comfort data from the facility would provide more practical information towards future strategies for the Hanok residence.

This paper alms to describe the indoor-outdoor air quality in school environment through the analyses of heavy metal concentration by inductively Coupled Plasma(ICPI, which were observed at some school environment, such as traffic area, industrial area seme-industrial area, and residence area. The results are as follows : (1) Regardless Indoor and outdoor, the area with the highest concentration of heavy metal is industrial area followed by traffic area, residence area and semi-industrial area in descending order of magnitude. And the heavy metal concentration of indoor is higher than that of outdoor. (2) The main heavy metal components with more high level concentration of Indoor than those of outdoor are Zn, Al, Ca and these heavy metal concentrations are higher in class than In corridor and outdoor.

The changes of social climate in respecting differences and needs of each diverse groups and human equality have caused the disabled to persue quality of life, through enabling their lives more independent. The purpose of this research was to find out adequacy of the residence and living behavior of the hearing impaired. Though this reach it was expected to find out environment features which have become obstacle in maintain their life independent in normal way and the way of improving their environment. Small group workshop with three hearing impaired persons was implemented. Living behavior and physical environmental characteristic of dormitory and interaction between them were identified. The need of non auditorial communication for the hearing impaired found far beyond required guidelines of the disabled Act. Design professionals need more profound knowledge with and ethical and humanistic attitude to find and satisfy the need of disabled.

The estimation of material cycle of pollutants is necessary for the environment management in coastal zone. Model for material budgets are useful tools to understand the phenomena of natural system and to provide an insight into the complex processes including physical, chemical and biological processes occuring in natural system. Budgets of fresh water, salt and nutrients were estimated in order to clarify the characteristics of seasonal material cycle in Keum river estuary. Inflow volumes of freshwater into system was approximately 1.014×10/sup 8/～12.565×10/sup 8/m³/month and discharge in Keum river has occupied 99.7% of total freshwater. Seasonal variations of freshwater volume in the system were found to be very high in the range of about 4 ～ 14 times due to rainfall in summer season. Existing water mass of freshwater in system calculated by salt budget was approximately 0.339×10/sup 8/～0.652×10/sup 8/m³. Mean residence time of freshwater was calculated to be about 1.6～10.0day, and exchange time was calculated to be about 2.2～11.9day. Mean residence time was short as 1.6day in summer due to precipitation, and long as 10.1day in winter due to a drought. Inflow masses of DIP and DIN were approximately 5.57～32.68ton/month and 234.93～2,373.39ton/month, respectively. Seasonal inflow mass of DIP was larger than the outflow mass except for summer season. Thus, we postulate that accumulation of DIP in the system will happen. Residence times of DIP and DIN were calculated to be 1.1～6.4day and 1.8～10.9day, respectively. The ratio of water residence time versus DIP, DIN residence time was calculated to be 0.39～2.31 times and 0.83～1.13 times, respectively.
