The purpose of this paper is to investigate the planning characteristics of certain cases of elderly welfare housing (hitherto EWH), and analyze any problems by comparing this against the actual needs of potential residents. To this end, 38 distinct housing plans from twelve EWH built after 2005 were examined, and a survey on housing needs was taken by 198 people between 48 and 62 years of age. The results are as follows: Firstly, the most common size found among the 10 cases was 42-66 $m^2$, however larger sizes are becoming more frequent. The most popular response on the survey was one favoring smaller housing options. Secondly, the most common floor plan examined consisted of 1 bedroom + LDK and 2 bedroom + LDK. Likewise, the survey reflected that 1 or 2 bedroom housing was preferred. Thirdly, a floor plan composed of a smaller bedroom and LDK is commonly found in smaller floor plans of EWH. The survey reflected potential residents preferred this same style of floor plan, with a smaller bedroom and LDK set up. However, lower-income participants preferred a single, larger bedroom which also can serve as a living space, to go along with a kitchen/dining room (DK). Fourthly, 2 bedroom housing typically included a single bathroom, however the survey indicated that participants preferred a second bathroom to go along with a second bedroom. Consequently, the planning of elderly welfare housing is to a large extent meeting the demands of its potential residents, however house size and the planning of bathrooms have yet to meet these demands, especially with potential lower-income residents when it comes to housing size and space composition.

The purpose of this study is to present the basic direction of the desirable spatial plan for elderly care facilities by analyzing the spatial characteristics of elderly care facilities in gyeongnam-province. As a research method, 189 elderly care facilities in gyeongnam-province were investigated for location conditions, site area, floor area, total floor area, and space composition. In addition, the area of each specific space was analyzed for two elderly care facilities with a typical floor plan. The results of the survey and analysis are as follows. First, the average number of people in the facility was 53.8, and the number of people in the facility needs to be planned to be medium or less so that they can live in a more comfortable environment in the future. Second, in the location type, it was found that many facilities were distributed in the order of suburban and rural type, urban type, mountain type, and waterfront type. In addition, in terms of facility space composition, the proportion of detached facilities was 50.8%. Complex facilities require a reasonable plan in consideration of the location type and other functional facility characteristics. Third, the average total floor area per person of elderly care facilities was 27.57m². There is a limit to constructing a unique nursing space. In the composition of bedrooms, quadruple rooms account for 67.4%, but it is necessary to expand the proportion of bedrooms that can be used by fewer people.

Length of a vehicle is an important variation to generate different variants of an automotive platform. This parameter is usually adjusted by embedding dimensional flexibility into different components of the Body in White (BIW) including the floor pan. Due to future uncertainties, it is not necessarily possible to define certain values of wheelbase for the future products of a platform. This work is performed to add flexibility into the design process of a length-variable floor pan. By means of this analysis, the cost and time consuming process of optimization is not necessary to be performed for designing the different variants of a product family. Stiffness and mass of the floor pan are two important functional requirements of this component which directly affect the occupant comfort, dynamic characteristics, fuel economy and environmental protection of the vehicle. A combination of Genetic algorithm, GMDH-type of artificial neural networks and TOPSIS methods is used to optimally design the floor pan associated with arbitrary length of the variant in the defined system range. The correlation between the optimal results shows that for a constant mass of the floor pan, the first natural frequency decreases by increasing the length of this component.

Recently, the flat-plate structure is widely used because it has many advantages such as reduction of story height, long span etc than the RC rahmen structure. Furthermore, application of the flat-plate is on the increase because of flexible plan unlike wall structure. Long span have been at a disadvantage for vibration serviceability evaluation, however studies about vertical direction vibration of flat-plate structure has not been carried out. This study analysis the characteristics according to slab structure to make an experiment on vibration and floor impact noise for the flat-plate structure in construction performance laboratory in Kolon E&C R&D center, the flat-plate structure applied to the post-tension method, and the wall structure in apartment houses.

The paper aimed to find out the lateral behavior of outrigger system in high-rise building considering floor diaphragm. To achieve this goal, a structural schematic design of 80 stories building was conducted by utilizing MIDAS-Gen. In this research, the key parameters of the structure analysis were the outrigger location in plan, the slab stiffness, the outrigger stiffness and the kind of diaphragm. For the purpose of this study, we analyzed and studied the lateral displacement in top floor, the story drift and the stress in slab. The research results indicated that the outrigger location in plan, the slab stiffness, the outrigger stiffness and the kind of diaphragm had an effect on lateral behavior in outrigger system of tall building. And the results of this analysis research can provided the assistance in getting the basic data of structure design for looking for the lateral behavior of outrigger system in the high-rise building.

The objective of this study is to find out the recent trends of hanok design based on 58 hanoks appeared in architecture magazines in the last 10 years. The cases are analyzed in terms of location, size, building form, spatial organization, material, roof form, and the ceiling form of living room. The consequences of this study is as follows; Most of the recent hanoks are built in rural area (91.4%), which shows the hanok is not accepted as an urban house type. Hanoks tend to be built in 2 stories whose 2nd floor is smaller than the 1st floor. (34.5%) The preferred size is total floor area of $99.2{\sim}165.2m^2$ (62.0%), 3 rooms (46.6%) with a traditional ondol room (60.3%). The buildings with ㄱ-shape (43.1%) and linear-shape (27.6%) are preferred, and the compact plan type similar with apartment house appears (13.8%). In the roof design that greatly influences the appearance of building, the traditional design factors such as half-hipped roof (55.2%), double eaves (27.6%), and eaves curve tend to be sustained. In terms of spatial organization, most of recent hanoks have double-layed plan (74.2%). The living room mostly has separately defined space. (82.8%) The indoor and outdoor tend to be connected by a narrow wooden veranda (39.7%), while some cases don't have any wooden floor space (48.3%). The entrance is adopted as an important spatial element in front part of building (75.9%), and it influences the appearance of building. The living room, the counterpart of the wooden floor hall in traditional hanok, and kitchen tend to be interiorized. In terms of material, the cement roof tile and red clay brick are preferred. Consequently, the walls of recent hanoks have the image of brick structure rather than the wooden frame structure of traditonal hanok.

The height provisions, by the urban planning, describe the hightest height per width division, also define oblique line limitation by road without mentioning the highest per width division. Therefore this study will be a basic model for the standard of measuring the highest height per width division analysizing the propriety of current standard of oblique limitation. This technique is prepared to prevent the confusion and to complements the existing planning method. Therefore, it takes more time to establish this new method and to apply it to the existing condition. This study reviewed density control in District Units Plan, based on the guidelines of density, which included height, ratio of total floor to ground area, and land distribution. This study aims to provide efficient analysis by using current oblique limitation provisions Thus, proving the area rations of general residential areas are decreasing. Since the purpose of the District Units Plan is to avoid confusion and help ease the existing problematic conditions which have risen from the two above-mentioned conventional systems, further observation and research on these areas are necessary.
