Today, our lifestyle and residential culture has been changed have been changed by interchange with various countries in various sides. In order to become an internationally recognized residential environment designer in this environment, we must understand the housing viewpoint of residents in a country first. Therefore, this study was intended to obtain useful material for residential environment design of both countries by comparing the housing viewpoint between Chinese students studying in Korea and Korean students. A questionnaire was conducted on 205 Korean students and 193 Chinese students (Korean race) from Y University in random sampling basis. The result is as follows. First, both Korea and China have a higher ratio of apartments in both current and previous types of house. But, both Korea and China have similar ratios between detached house and apartment for a desired type of house at the time of moving in. Second, Korean and Chinese university students consider and as the most important functions of residence, and Chinese university students consider more functions of residence than Korean students. Third, both Korean and Chinese consider a living room as the most important space among housing spaces, but Chinese consider a private room more importantly than Korean. Fourth, overall satisfaction rate of Korean students for current houses was average, and most Chinese students were generally satisfied with their houses.

Trip demands and patterns on weekends have been changed significantly over the past decade due to the income growth and the spread of the 5-day workweek in Korea. The increased weekend trips for shopping, leisure activities, entertainment and friendship have exacerbated traffic congestion in major highways or principal arterial roads from Friday afternoon through Sunday. Therefore, it is necessary to focus on travel demand forecasts and transport policies for weekend trips by investigating specific characteristics of the trips. Previous research efforts focus on simple analysis of characteristics of weekend trips and comparison of travel characteristics between weekdays and weekends. The paper analyzes the differences between weekday and weekend trips via statistical analyses to derive multiple types of characteristics of weekend trips, and develops Tobit models to identify key factors that may affect the number of trips, using Seoul city's weekend trip survey data in 2006. The model results show that weekend trips appear differently from weekdays by household or individual characteristics. Age, residence area and type of residence affected the number of trips, regardless of the type of the day, whereas gender, occupation, income, presence of household vehicle showed different impacts on trips between weekdays and weekends.

In case of Senior Hospitals, meticulous care is required in both amount and quality of natural lighting because of the semi-long term residence of patients. Natural lighting has a huge impact on the physical and psychological part for the seniors. Likewise, natural lighting is an important factor considered for hospital design because it can also effect hospitalization period of patients. Research subject was K Senior Hospital which was determined as the courtyard-type building made to provide healing environment through natural lighting. Analysis was performed by dividing the space of K Senior Hospital into Central Treatment Department directly used by patients, Outpatient Department(OPD), Ward Department, Common Use Department. Research was carried out in two ways of integration value analysis using SPACE SYNTAX and illumination intensity analysis using ECOTECT. K Senior Hospital intended to actively let in natural light through courtyard and to make patients exposed to natural light when they walk along the circuit corridor built around the courtyard. This environmental consideration affected the utilization rate of Common Use Department and residence time of patients raising the average of Common Use Department on every floor. As a resuit of this study presenting type C and type D, part of four types of illumination intensity, takes higher percentage of almost every spaces compare to the others therefore K Senior Hospital was designed on the assumption of healing environment composition through natural light. The result of this research would be used meaningfully in the space programming phase of Senior Hospitals in the future. Utilization rate can be adjusted using illumination intensity value in the space that integration rate should be planed to be high. The use(purpose) of space and integration rate can be used as a guideline to set illumination intensity of natural.

The purposes of this study are to identify many implications of commuting regional type according to the features of foreigner commuting. Research on the pattern of distribution of foreigners has been very simple and limited because foreigners usually lived together in a specific area, and their workplace often tended to be their residence. However they currently live dispersed more Widely, and their job and housing increasingly tend to be mismatched. This study divided areas inhabited by foreigners into general one characterized by job-housing match and exceptional one characterized by job-housing mismatch, and then examined the features of foreigner commuting. General commute type showed a high rate of intra area commute and foreign workers' universal features. Inflow commute type showing high E/R ratio. In these areas, outflow commuters had a short journey to work while inflow commuters had relatively a long journey to work, and professionals accounted for a high proportion of employees. Outflow commute type showing low E/R ratio. In these areas, outflow commuters had a long journey to work while inflow commuters had a relatively short journey to work. The composition ratio of three commute types was different according to nationality and visa type.

Coal gasifier is a key component for achieving high efficiency in integrated gasification combined cycle and indirect coal liquefaction. Although there have been several successful coal gasifiers that were commercially proven, many different design configurations are still possible for a simple and reliable gasifier operation. Four different gasifier design concepts of dry-feeding were compared in terms of residence time, exit syngas temperature and syngas composition. First, cold-flow simulation was applied to pre-select the configuration concepts, and the hot-flow simulation including chemical reactions was performed to compare the concepts at more actual gasifier operating conditions. There are many limitations in applying CFD method in gasifier design, particularly in estimating slag behavior and slag-tap design. However, the CFD analysis proved to be useful in comparing the widely different gasifier design concepts as a pre-selection tool.

The surface hydrology of large land areas is susceptible to several preferred stable states with transitions between stable states induced by stochastic fluctuation. This comes about due to the close couping of land surface and atmospheric interaction. An interesting and important issue is the duration of residence in each mode. Mean transition times between the stable modes are analyzed for different model parameters or climatic types. In an example situation of this differential equation exhibits a bimodal probability distribution of soil moisture states. Uncertainty analysis regarding the model parameters is performed using a Monte-Carlo simulation method. The method developed in this research may reveal some important characteristics of soil moisture or precipitation over a large area, in particular, those relating to abrupt change in soil moisture or preciptation having extremely variable duration.

Children of three-to-eighteen-years-old have been brought up in the institution (Orphanage) for several reasons such as family dissolution, divorce and poverty since the Korean Was of 1950. The Cottage, where these children are housed and brought up has dining room, library and bedrooms, plays as a significant social interaction place as well as study. Since the most facilities were built during the 1950-1960s period, most of the cottages are now in the condition of being rebuilt or remodelled. Because living space and studying space are mixed, it will be necessary to provide another studying space separated from living space. And then it will be also necessary to provide a space for play or rest between the two spaces. This study was conducted to obtain some basic data necessary for design of spaces in the orphanages by examining the relations between the studying activities of children and residence types.
