The purpose of this study is to provide a fundamental data for reducing energy consumption and greenhouse gas emission of detached houses by investigating the energy consumption characteristic of detached houses in Daegu. Although the ratio of the detached houses decreases, the detached houses are common dwelling form next to apartments. Nevertheless the study about the energy consumption of detached houses has been insufficient compared apartments. There is a necessity which will investigate the energy consumption characteristic of detached houses. Because that with the building quality which is various form is different from apartments. This study investigate construction and equipment conditions and analyzing effective factors on energy consumption of detached houses. And this study draw up the energy consumption unit and emission factors unit for greenhouse gas of detached houses. This study represent a basic report for energy consumption reduction and helps effective use of energy.

Many researchers have been studied with guard cell protoplasts and detached epidermis as they think that properly stabilized protoplasts and detached epidermis retain many of the properties of intact guard cells. However, some studies have shown that stomata in detached epidermis behave differently, both quantitatively and qualitatively, from those in the intact leaf. Stomata in the intact leaf are very sensitive to environmental factors such as light, $CO_2$ and osmotic stress, but stomata in detached epidermis are less sensitive to these factors than those in the intact leaf. The clearest evidence to suggest the different response between detached epidermis and intact leaf obtained from the experiments with heavy metal, cadmium. 3-weeks old Commelina. communis was transferred to and grown in Hoagland solution in the presence or absence of 5 mM $Cd^{2+}$ for 4 days. The application of $Cd^{2+}$ showed about 70% inhibition of stomatal conductance when measured at various light intensity (100-1,000 $\mu$mole $m^{-2}s^{-1}). However, stomata in detached epidermis floated on an incubation medium containing 100 $\mu$M $Cd^{2+}$ opened to a degree of about 8.38 fm, but the stomata treated with no cadmium opened to 3.74 ${\mu}{\textrm}{m}$. These results were unexpected as the intact leaf grown in a Hoagland solution containing cadmium showed very negative physiological responses. These results showed that stomata in detached epidermis and in the intact leaf could respond reversely. Therefore, it is possible that we now misunderstand how stomata open in real natural condition.

To analyze the space features of small-sized detached houses, this study has compared the floor plan types of detached houses and apartments. Currently small-sized detached houses are popular in Korea. The comparative analysis was focused on common residential patterns and the apartment plan. The results of space syntax were summarized as follows: four types of apartments and twelve types of small-sized detached houses were deduced by the relative spatial depth analysis. Among the sixty-seven house samples, only two of them showed the same pattern as those of apartments, which showed that each room of detached houses had distinct difference with those of apartments. According to the integration and control analysis, each space of apartments showed difference within narrow range, while the space of detached housed showed difference within wide range. In addition, the detached houses showed distinct relations between the center of space and the surroundings, and there are distinct differences between the easier layouts for access rooms and difficult ones. Moreover, the living rooms of detached houses somewhat exist under the low integration condition, and they cannot be standardized in the center of house, which are different with those of apartments. The master bedrooms of detached houses exit at the surrounding space same as those of apartments. Nevertheless the toilet is in the master bedroom which made its control lower than those of apartments.

This paper examines the changes in housing characteristics occupied by two or more households from 1995-2005, as a replicated follow-up study done by the previous decade of 1985-1995. The data analyzed were based on the Population and Housing Census in 1995, 2000, and 2005 by the Korean National Statistical Office. Results showed decreasing trends in the percentages of housing units occupied by multi-households and of households sharing a housing unit, while the average number of households for a shared housing unit was increasing. Detached dwellings in dongs (neighborhood) including ordinarily single-family detached ones, mainly multi-family houses, were the most often shared with other households even in the trend of the decreasing number of the detached housing. Further research is suggested to focus on housing circumstances of households sharing a detached dwelling in Dongs by the type of detached dwellings.

The purpose of this study is to analysis the environmental characteristics in the small urban village consist of the detached houses. Three detached houses with the different urban structure and physical characteristics are selected, we survey the physical characteristics and investigate the residential satisfaction. As a result of the study, (1) A loop street pattern is more desirable for a community than a grid pattern, (2) The wall of the residential boundary makes residents get the sense of territory and community, and it facilitates no wall or tree fence of the each detached house. (3) The community spaces have an effect up on the sense of community. (4) It is desirable that the residents participate in a management of the detached housing area.

The purpose of this study is to investigate the effect exchanging water supply on the' rainwater in detached house. It is difficult to decide water supply amount for a closet in detached house, Therefore, to obtain water supply for closet in detached house, it used regression equation using 1,569 data of frequency of used closet and during 120 days. In detached house, the frequency of used closet is 14.6 times/day and water supply amount is $219 {\ell}/day$. The optimum rainwater tank size which is decided by regression equation and using weather data is $8.5\;m^3$. The effect exchanging water supply on the rainwater in detached house is up 50%.

The purpose of this study is to investigate the effect of Ondol on the bedclimate, microclimate and physiological responses of occupants. Four healthy female subjects slept for seven hours in thermal environment of detached house and apartment respectively. Their bedclimate, microclimate, skin temperature, weight loss of body, weight of bedcloth and sleepwear, body movement and subjective sensation were measureed for this study. The results were as follows; The differences of bedclimate, microclimate, skin temperature were significant according to season and residence styles. The occupants of the detached house showed higher temperature and humidity inside quilt and clothes than those of the apartment did on apartment environment. The occupants of the detached house showed higher weight losses of body, heavier weights of quilt than those of the apartment did on apartment environment in the spring, autumn and winter, lower weight losses of mattress in the autumn and winter. The occupants of the detached house moved more than those of the apartment on apartment environment when sleeping. The occupants of the detached house felt higher thermal sensation and lower humidity sensation than those of the apartment did. The occupants of the detached house felt more comfortable than those of the apartment on detached house environment, while the occupants of the apartment felt more comfortable than those of the detached house on apartment environment. The thermal environments of the apartment and the detached house had an effect on the bedclimates, microclimates of occupants and therefore the physiological responses such as skin temperature, rectal temperature, weight loss of body, perspiration and subjective sensation are different during sleeping according to their residential styles on the same environment.

In South Korea, problems such as low fertility, aging population, and income polarization have recently become more serious. In this time of social change, it is necessary to examine the current changes occurring to residences in order to improve the stability and health of residential areas. The purpose of this study is to investigate the changes of residential areas that occurred between 2000 and 2010 based on detached houses, which are the foundation of residential areas in Seoul. Changes in residential areas can be observed by examining changes in the type of housing and the characteristics of the residents. Since the type of housing and the characteristics of the residents change in the same area, it is necessary to study them together, not as individual elements. Census data is suitable for this purpose, because it can show the changes that have occurred to the housing type and the residents' characteristics within the neighborhood unit. Among the census output areas identified as residential areas based on detached houses, six sites were selected as the case study area based on the rate of change of detached houses. From the result of the case study using the census data, the study area was categorized into three regional types: (i) an urban development and redevelopment area; (ii) an area with a concentration or increasing number of detached houses; (iii) an area with an increasing number of multi-family houses based on detached houses.

The purpose of this study is to provide the information about improvement method of the detached housing area for children's outdoor activities. This study was accomplished by two research methods; the evaluation of physical environment of two detached housing areas, and the analyzation of satisfaction & consciousness of 190 residents. Outdoor spaces of detached housing area were divided into 6 areas (play space, education facility, commercial facility, green space, street space, and empty space & parking lot). And then, 6 outdoor spaces were evaluated about the physical characters such as accessibility, network, safety, variety, functional, natural elements. Also, the survey for resident's satisfaction and consciousness was used the Likert scale. According to the result of this study, many parts of the detached housing area were not good for children's outdoor activities, and the resident's satisfaction was low. In the sample detached housing areas, negative factors were car and motorcycle. And many residents pointed out the lack of natural elements, variety, and safety of outdoor space in dwelling area. Finally, this study suggested the several constitution method for the children's activities based on the results of evaluation and survey.
