The purpose of this study is to provide the planning factors of housing for the disabled and elderly based on the inclusive housing design as sustainable neighborhood. The goal of inclusive design is to make buildings and communities more livable for all type of people. Inclusive design should embrace other good design goals and reinforce them, not work against them. To carry out this purpose, we should proceed in the following way: First, we deducted the four design factors (the basic, recommendable, adaptable, and residential factors) by reviewing the characteristics of inclusive housing concepts. Second, we analyzed the related foreign design standards and guidelines such as the ICC/ANSI A117.1 Type C Units (the United States, 2009), Lifetime Standard (the United Kingdom, 2010), and Livable Housing Design Guideline (the Australian, 2010) through four design factors based on inclusive design concepts. Finally, we suggested the housing design factors for the disabled and the elderly in Korea. To conclude, we can make the followings: It is important basic factor that the bedroom and bathroom layout closed to each other. Also, the bedroom has the proper height of light switches, outlets, and windows. The recommendable factors take into consideration stairs and ramp, if existent. The adaptable factors are closely related to domestic housing culture as well as residential factors. Proceeding from this fact, the livability for people with disabilities and older requires accessibility and adaptability that take into account public and efficiency considering the current trend of housing development and urban planning.

KEPRI has studied planar type SOFC stacks using anode-supported single cells and kW class co-generation systems for residential power generation. A 1kW class SOFC system consisted of a hot box part, a cold BOP part and a water reservoir. A hot box part contains a SOFC stack made up of 48 cells with $10{\times}10cm^2$ area and ferritic stainless steel interconnectors, a fuel reformer, a catalytic combustor and heat exchangers. Thermal management and insulation system were especially designed for self-sustainable operation. A cold BOP part was composed of blowers, pumps, a water trap and system control units. When a 1kW class SOFC system was operated at $750^{\circ}C$ with hydrogen, the stack power was 1.2kW at 30 A and 1.6kW at 50A. Turning off an electric furnace, the SOFC system was operated using hydrogen and city gas without any external heat source. Under self-sustainable operation conditions, the stack power was about 1.3kW with hydrogen and 1.2kW with city gas respectively. The system also recuperated heat of about 1.1kW by making hot water. Recently KEPRI developed stacks using $15{\times}15cm^2$ cells and tested them. KEPRI will develop a 5 kW class CHP system using $15{\times}15cm^2$ stacks by 2010.

Due to difficulty of marriage with women in Korea, unmarried men in countryside tend to have an international marriage. A ratio of international marriage was 3.7% in 2004, but increased by over 10% in 2004 due to the change of population composition in countryside. Without social or national preparation on a multicultural family and an increase of elder who lives alone made problems such as changes of population composition in countryside, a high rate of divorce due to differences on culture and society. These problems are becoming critical problems in countryside, not only for a family. This Study has a purpose as below, Firstly, this study will examine living place of elder who live alone and multicultural families. Secondly, characteristics of using each space will be analyzed and then surveyed efficiency and satisfaction. The result of survey will be provided to space planning for improvement of living standard. The results of this study can be summarized as follows: The characteristics of the surveyed households, the elderly ratio of 70 to 80 units high, and when the elderly become less than 10 years, 51.6%, 77.4% of women were overwhelmingly high. The characteristics of multicultural families in the in the middle or early 2000s when immigration is concentrated and national origin in Vietnam was 66.7 %. Housing characteristics of households with elderly housing type, the ratio improved to 61.3% is Majority. Type strain and 29% in traditional houses, traditional housing type is 9.7%. And house of multicultural families improve housing type is 87.5% Majority. The main space of the housing for the elderly, most are usually satisfied. But generally low level of self-determined housing survey confers real. These results have lived a long time because of space adaptation and can be viewed as attachment. For the elderly passive use of space and simplify the Act and heating cooling at the expense of the use of housing space due to the reduction, but multicultural families is the space required for the growth of their children because there are more modifications required.

We investigated the extent of recognition and the rate of class practice on the contents relevant to the environmental education in the units of 'Clothing Life' of the 7th 'Technology-Home Economics' curriculum in Korean middle school teachers. Two hundred sixty teachers, who had taught the units of 'Clothing Life' and responded to the questionnaires by mail from December 2007 to January 2008, were enrolled and each item in the questionnaires was analyzed in this study. Most teachers recognized the serious environmental issues in their residential area resulting in a harmful influence on their lives. Also they exhibited increased practice will such as joining to the environmental organizations and showed high practice of the environmental preservation. They commented relatively high rate of class practice on the contents relevant to the environmental education and enhanced practice of the environmental preservation in all units of 'Clothing Life' of the 7th 'Technology-Home Economics' curriculum except the units of 'Clothing Skill and Dress Clothes' and 'Simple Clothes Making'. Moreover, teachers with higher age and longer teaching career had the higher level of recognition and the greater rate of class practice on the environmental education compared to those without. Teachers should try to raise the students' recognition and practice will on the environmental issues in the class of 'Clothing Life' of the 7th 'Technology-Home Economics' curriculum in Korean middle school.

Objectives: The aim of this study was to analyze and classify the characteristics of potential damage from hazardous chemical accidents in 229 administrative units in South Korea by reflecting the social and environmental characteristics of areas where chemical accidents can occur. Methods: A number of indicators were selected through preceding studies. Factor analysis was performed on selected indicators to derive factors, and cluster analysis was performed based on the factor scores. Results: As a result of the cluster analysis, 229 administrative units were divided into three clusters, and it was confirmed that each cluster had its own characteristics. Conclusions: The first cluster, "areas at risk of accident occurrence and spread of damage" was a type with a high potential for accident damage and a high density of hazardous facilities. The second cluster, "Urban infrastructure damage hazard areas" appeared to be a cluster with high urban development characteristics. Finally, the third cluster 'Urban and environmental damage hazard areas' appeared to be a cluster with an excellent natural environment. This study went further from the qualitative discussion related to existing chemical accidents to identify and respond to accident damage by reflecting the social and environmental characteristics of the region. Distinct from the previous studies related to the causes of accidents and the response system, it is meaningful to conduct empirical research focusing on the affected areas by analyzing the possibility of accident damage in reflection of the social and environmental characteristics of the community.

Purpose: The energy consumption of apartment units is affected by the lifestyle of the residents rather than system technology. In this study the numerical analysis of assumed energy consumption correlation factors with arbitrary value due to uncertainty. It is intended to be used as a simulation correction value which can be utilized as a predicted value of actual energy usage. The correction value of the simulation is set in the developed form of the existing process that derives the actual usage amount. The simulation results used in the existing evaluation system are used to maintain the useful value as the current system evaluation scale and predict the actual capacity. Method: The method of the study is to statistically analyze the data frames of all complexes capable of collecting the annual energy usage and to reconstruct the population by adding the variables that are expected to be correlated. Repeat the data frame configuration with variables that are assumed to be highly correlated with energy use levels. Determine whether there is correlation or not. The intensity of the external characteristics of the building equipment related to the energy consumption is presented as the quantitative value. Result: The correlation between electricity consumption and trading price since 2010 is analyzed as (Correlation coefficient 0.82). These results are higher than (Correlation coefficient 0.79), which is the correlation between residential area and trading price. This paper signifies the starting point of the methodology that broadens the field of view of verification of simulation feasibility limited to the prediction technique focused on the simulation tool and the element technology scope.The diversified phenomenon reproduction method develops the existing energy simulation method.It can be completed with a simulation methodology that can infer actual energy consumption.

Even though the structural safety is confirmed in the design stage, the structural safety is not guaranteed in the construction stage because the structural system is not completed. In addition, since the construction period is shorter than the period of use of the building after completion, it is excessive to apply the same seismic load to the construction stage as in the design stage. ASCE 37-14 presents the concept of seismic load reduction factor during construction, but does not provide a clear application method. Therefore, in this study, the seismic load reduced according to the return period was applied to the example model of a residential middle-rise RC building. The construction stage of the example model was divided into five-story units, and seismic load with the change of the return period was applied to the construction stage models to analyze the change of seismic load during construction and to check the sectional performances of structural members. By comparing the design strength ratio of the shear wall at the design stage and the construction stage, the range of seismic load magnitudes that can assure the safety during construction of a residential middle-rise RC building was analyzed in terms of the return period.

Four parks were selected to study the current situation after large scale suburban housing development in the 1990s. Since housing development road network have expanded with other facilities. First of all, green space area available per housing unit is 7.11- 22.0 sq. m. These parks neither extend as green corridor with surrounding hillside mountains (the river or lakes) nor act as the wind path from the mountains. Some housing units have reconstructed and the others will be redeveloped in near future which would more challenges for the residents in terms of quality of their life.

Catastrophe models appraise the natural risk of the built-infrastructure simulating the interaction of its exposure and vulnerability with a hazard. Because of unique configurations and reduced number, mid/high-rise buildings present singular challenges to the assessment of their damage vulnerability. This paper presents a novel approach to estimate the vulnerability of mid/high-rise buildings (MHB) which is used in the Florida Public Hurricane Loss Model, a catastrophe model developed for the state of Florida. The MHB vulnerability approach considers the wind pressure hazard exerted over the building's height as well as accompanying rain. The approach assesses separately the damages caused by wind, debris impact, and water intrusion on building models discretized into typical apartment units. Hurricane-induced water intrusion is predicted combining the estimates of impinging rain with breach and pre-existing building defect size estimates. Damage is aggregated apartment-by-apartment and story-by-story, and accounts for vertical water propagation. The approach enables the vulnerability modeling of regular and complex building geometries in the Florida exposure and elsewhere.

The main goal of this research was to understand housing environment as well as the living behaviors of Korean people who reside in foreign countries. This study includes examination of dwelling units, especially focusing on dwelling behaviors by space types, arrangement and use of the space, and the according residence patterns of the Koreans in the United States. Focus group interview method and survey method were conducted; photography were taken as a visual evidence; and results were analyzed by researchers. This study strongly indicates that most of Koreans try to keep their own way of living in foreign cultures and rather readjust the housing spaces and living patterns to their own culture. The results from this study have limitations in generalizing all Korean families living in foreign cultures, because a convenience sample was used. Although studies of Korean families in Columbia, MO may not provide information that can be generalized to the entire population of Koreans overseas, we expect that this study provides useful insight in understanding and estimating the future trends in residential planning for Koreans.
