Korea has been expanding its housing supply through the housing land development such as new cities and the development of large apartment complexes in order to solve the explosive increase in housing demand due to the economic growth since 1980s. In recent years, there has been a growing interest in the quality level of housing along with the supply of such quantitative housing and the demand of quality of housing is increasing to such an extent that the quality level of housing is regarded as a measure of quality of life. Such quality of housing can varied depending on the housing environment; it can be changed depending on the housing size such as the land area, the building floor area, the exclusive residential area in case of the apartment, etc., and also varied depending on such the facilities existing internally and externally in the housing as the water and sewage facilities, the heating facilities, the supplementary facilities, etc. In addition, the regional environment in housing concerned such as commuting from home to jobsite/school, convenient use of the market, safety of housing, daylight, ventilation and the like can have an effect on the quality of residence. Therefore, this study intends to find out the difference of satisfaction with housing environment according to the characteristics of housing by dividing regions on basis of their sizes by the indices of housing characteristics targeting the cities or counties of Gyeongnam area and comparing and analyzing the satisfaction with housing environment by region. Furthermore, it aims to draw regional factors affecting the satisfaction with housing environment through analyzing the satisfaction with housing environment based on housing characteristics by region. Through it, the purpose of this study is to draw improvements of the environmental environment by region in local areas and provide implications as the basic data of the regional housing policy in the future.

Congenital cystic adenomatoid malformation of the lung(CCAML) is rare fetal developmental anomaly characterized by adenomatoid hyperplasia of terminal respiratory structure with cystic formation of varying sizes, and pulmonary sequestration is rare congenital thoracic defect characterized by an accessory or dysplastic segment of lung that is supplied by a systemic artery but may be anatomically distinct from the remainder of the lobe. CCAML and pulmonary sequestration occasionally coexist. We experienced a case of type Ⅲ CCAML accompanying with extralobar pulmonary sequestration in 33 years old pregnant woman, so present this case with a brief review of related literature.

Today, Korea is faced with some problems such as decrease of population in local cities and urban decay, because of continuous overpopulation in the Metropolitan area as well as decline of population and aging phenomena. Many local cities lose their competitive power and undergo atrophy of local economy and weakening of self-sufficient city"s function. Thus, the local policy to promote self-support and co-prosperity through an effective connection between city and locality is required, and the regional welfare settlement area policy in the preset Korea can be seen as a plan for local connection development across city, county and district, according to decrease of population in local city and simultaneous decay of rural community. However, the establishment of regional welfare settlement area should not be limited to simple connection of administrative units or delimitation by geographic administrative boundary, and the settlement areas are needed to be decided by considering life patterns such as going to work, school attendance, shopping and leisure of actual residents. Thus, this study attempts to perform the delimitation and connection between regions according to travel outflow and influence by each purpose, by analyzing the travel by inter-regional purposes of Metropolitan cities, towns and counties in Busan, Ulsan and Gyeongnam which are included in southeast part of Korea. Hence, it aims to be provided as basic data for the establishment of regional settlement areas as well as reference for local development policy.
