The purpose of the this study was to provide the basic information about the formation background of urban squatter and their housing state in Korea. This study was progressed on the basis of socio-historical point of view from after the Korean War to the present time. Therefore, this study considered the meaning of housing for urban squatter in the Korean housing history. For this study, the formation background of urban squatter was divided into five periods. The first one was the period of the policy on the mass migration (1955-1960) after the Korean War. The second period was the period of reproduction of deteriorated residential area (1960-1970) for the continuing mass migration policy. The third was the period of disbanding of deteriorated residential area (1970-1980) for redevelopment. The forth period was before the IMF (1980-1997) broke up the deteriorated residential area. The fifth period was after the IMF (1997-) produced the new poverty due to the unemployment and the business failure. Thus, such social change increased the number of urban squatter and created the new type urban poor.

In case of general residential house, photovoltaic can be installed at roof, wall, and any other places. But, in case of apartment building, there has not enough roof space to install photovoltaic panels to supply enough electricity. Actually, apartment building roof and facade wall (exclude the balcony window space) is not enough space to produce and supply the electricity to residents by installing PV panel. Generally, the space of facade balcony with windows in facade wall at apartment building occupied about $70{\sim}80%$, in all facade space. So, if we could use the balcony and windows space in facade as PV to generating electricity, there could contribute the energy saying. But, PV cell is opacify. So if it installed at front window area in apartment building, residents may have displeasure for that opacity character. But the other hand, residents are not always in house especially in day time that is exactly good time for generating electricity by PV. If we can use PV at the facade balcony with window without collusion of resident's displeasure, there have good attraction to using sustainable energy. Hence, this study suggests the design of facade balcony window style PV by considering resident's living pattern in apartment building. The methods of this study are as follows. At first, this study surveyed to the residents about residential time in their home and asked user demand by Delphi survey. At second, this study designed balcony open style PV system which oriented to the user demand. At third, this study tests designed result performance by computer simulation that compared design result with old design. As a result, For the purpose of satisfying the resident demand, there designed sliding window style which slide the several door systems to the one side. That would be make balcony absolute open scenery to the residents. Hence, the designed system performance results were as follows. When we compare the small apartment and large apartment, smaller one has good performance than larger one. Because resident's residential time characteristic. And that has more good electronic performance than vertical style that is similar to roof style.

This study aims to explore the issues of residential care services for children and youth with disabilities using mixed methods research. In Korea, welfare policies for people with disabilities tend to focus on adults with disabilities. As a result, children and youth with disabilities often receive less attention in welfare policies, which is especially true of children and youth with disabilities at residential facilities, who have confronted more serious situations than children and youth with disabilities living together with their families. Thus, the goal of this study explores the issues of residential care services for children and youth with disabilities, and suggests alternatives grounded in the research results. This study used a mixed methodology; in particular the embedded design that is designed by Creswell and Clark(2007). In qualitative research, representative professionals who work at residential facilities were selected using the recommendations of professional groups, and were interviewed using focus group interview methods. In quantitative research, this study investigated the thoughts of professionals on the issues of residential care services for children and youth with disabilities, using questions that were developed through qualitative research results. This study is significant in that it explored the issues of residential care services for children and youth with disabilities, focusing on field experiences, for the first time in Korea, and suggested political alternatives for the future.

Objectives: Respiratory virus infections are the most common disease among all ages in all parts of the world and occur through airborne transmission. The purpose of this study was to detect and quantitate human respiratory viruses in residential environments. Methods: Air samples were collected from the residential space of apartments in the Seoul/Gyeonggi-do area. The samples were collected from indoor and outdoor air. Among respiratory viruses, influenza A virus, influenza B virus, parainfluenza virus, metapneumovirus, respiratory syncytial virus, and adenovirus were investigated by multiplex polymerase chain reaction. Among the virus-positive samples, we performed adenovirus quantification by real-time polymerase chain reaction. Results: Virus detection rates were 44.0%, 3.8%, 3.4%, and 17.3% in spring, summer, autumn, and winter, respectively. The virus detection rate was higher in winter and spring than in summer and autumn. Adenovirus was most commonly detected, followed by influenza A virus and parainfluenza virus. Virus distribution was not significantly different between indoor and outdoor environments. Conclusions: Although virus concentrations were not high in residential environments, residents in houses with detected viruses may have an increased risk of exposure to airborne respiratory viruses, especially in winter and spring.

Residential electricity consumer can rent a photovoltaic power generator, whose profit can be exist if the decreased electric fee is larger than the rent fee. But the exact function of the profit have not expressed until now, which is shown in this paper. Two assumptions are supposed. The first assumption is that the generated electric power by the renting photovoltaic generator is 300kWh per month. The second assumption is that the rent fee 362300 won is paid once when the photovoltaic generator is installed. The earings rate, the payback time and the sensitivity of a low-voltage residential electricity consumer's profit consuming 401~1000kWh per month at a detached house for the initial 7 years is calculated by the induced exact function.

The renewable energy system and the real-time pricing can provide the significant economic advantage for end-user of residential house. However, according to recent studies, high initial cost of renewable energy system such as photovoltaic (PV) system and lack of suitable load control methods adjusting electric power consumption in response to time-varying price are regarded as the major obstruction for introduction of renewable energy system and real-time pricing in residental household. In this paper, we propose automated optimal load control strategy which aim to achieve not only minimizing the electricity cost but also the increase in the utilization rates of PV generation power of residential PV house in real-time pricing environment. Simulation results show that our proposed optimal load control strategy leads to significant reduction in the electricity costs and increase in the utilization rates of power generated by PV system in comparison with the conventional PV house. Therefore, the proposed optimal load control strategy can provide more economic benefit to end-user.

Objectives: The purpose of this study was to estimate the ventilation rate of residential homes in Korea through tracer gas methods using indoor and outdoor concentrations of carbon dioxide ($CO_2$) and $CO_2$ generation rates from breathing. Methods: In this study, we calculated the number of occupants in a home by time through data on the average number of people per household from the Korean National Statistical Office and also measured the amount of $CO_2$ generation by breathing to estimate the indoor $CO_2$ generation rate. To estimate the ventilation rate, several factors such as the $CO_2$ generation rate and average volume of residential house provided by the Korean National Statistical Office, indoor $CO_2$ concentrations measured by sensors, and outdoor $CO_2$ concentrations provided by the Korea Meteorological Administration, were applied to a mass balance model for residential indoor environments. Results: The average number of people were 2.53 per household and Koreans spend 61.0% of their day at home. The $CO_2$ generation rate from breathing was $13.9{\pm}5.3L/h$ during sleep and $15.1{\pm}5.7L/h$ in a sedentary state. Indoor and outdoor $CO_2$ concentrations were 849 ppm and 407 ppm, respectively. The ventilation rate in Korean residential houses calculated by the mass balance model were $42.1m^3/h$ and 0.71 air change per hour. Conclusions: The estimated ventilation rate tended to increase with an increase in the number of occupants. Since sensor devices were used to collect data, sustainable data could be collected to estimate the ventilation rate of Korean residential homes, which enables further studies such as on changes in the ventilation rate by season resulting from the activities of occupants. The results of this study could be used as a basis for exposure and risk assessment modeling.
