An operation planning of lift car is crucial in tall building construction especially it's arrangement plans, because it is related with transportation distance of finishing materials affecting construction productivity. Since tall building construction, composed of complicating and huge plane have complex traffic lines of finishing materials, to determine the position of lift car empirically or intuitively has limits. Therefore this paper suggest an optimum layout model of lift car minimizing the transportation distance both at site-level and floor-level using Graph theory and Dijkstra algorithm.

Hospital architecture is in a transitional period and faces a great change. Furthermore, patients' demand on medical service has been changing. It is said that the importance of public space for people as well as that of private space for patients, doctors and nurses becomes more important than ever. For example, corridor space becomes pathway, waiting room and rest area of patients. Accordingly, the importance of corridor space of public space in general hospitals is increasing. This study aims to present standard data for hospital planning by analyzing space allocation and floor area of corridor space in general hospitals.

Air Rights techniques, including floor-area ratio (FAR) transfers, FAR bonuses, and FAR storage, have been widely applied among skyscraper constructions in New York City for profit maximization goals. Since 1916, air rights regulations in New York zoning system have been revised and improved over the years to cater the urban development needs of different periods, and they also result in typical skyscraper block typologies. This research firstly performed spatial overlay analysis to reveal the spatial correlation between skyscraper blocks and air rights application blocks; secondly, Spacematrix parameters and cluster analysis are applied to divide the skyscraper urban block of New York City into four categories. Compared with air rights application data, the research attempts to illustrate how various air rights techniques have acted on the formation and evolution of skyscraper block typologies in the pre-1916, 1916-1961, 1961-2010, and 2010-present periods respectively, in order to reveal the relationship between public policies and urban morphology in a broader sense and also provide references for policy making in future.

Purpose: This study was designed to evaluate differences in the required visibility of anatomic structures according to the diagnostic tasks of implant planning and periapical diagnosis. Materials and Methods: Images of a real skull phantom were acquired under 24 combinations of different exposure conditions in a cone-beam computed tomography scanner (60, 70, 80, 90, 100, and 110 kV and 4, 6, 8, and 10 mA). Five radiologists evaluated the visibility of anatomic structures and the image quality for diagnostic tasks using a 6-point scale. results: The visibility of the periodontal ligament space showed the closest association with the ability to use an image for periapical diagnosis in both jaws. The visibility of the sinus floor and canal wall showed the closest association with the ability to use an image for implant planning. Variations in tube voltage were associated with significant differences in image quality for all diagnostic tasks. However, tube current did not show significant associations with the ability to use an image for implant planning. conclusion: The required visibility of anatomic structures varied depending on the diagnostic task. Tube voltage was a more important exposure parameter for image quality than tube current. Different settings should be used for optimization and image quality evaluation depending on the diagnostic task.

The purpose of this study was to understand the present condition about the space planning of the nursing rooms at the child care center in U.S.A. The researchers investigated the physical conditions of the centers through sketching, measurement, taking pictures and observation. On the other hand, to understand the user's needs, the interview to the directors of the centers was performed. As a result, the followings were proposed. The grouping of children depending upon the age has to be more classified according to the development period. And the guideline for the space areas has to be improved to a larger standard than present regulation. And the most impressive characteristic of the center in U.S.A. is the functional space design. The space such as toilet, washing room, kitchenet are well organized into the nursing rooms for children. Various ideas for arranging above functions in the small nursing rooms have to be developed in Korea. And the dynamic space arrangement of nursing room is also impressive. The material of the floor has to be considered variously for the comfort of the children.

The purpose of the study is to propose a simple formula of lifting times of finishing materials on establishing the high-rise complex building, it is expected to help the efficient planning of lifting. The planning of lifting the finishing materials becomes important as the buildings get higher. The efficient level of lifting times has been calculated from 'Packaging' to improve the existing studies on the planning of lifting ; 'Packaging' means 'Making a bundle as one unit' basing on the characteristics of the individual materials. The simple formula has been produced regarding two variables of the typical floor area and the number of rooms per area.

Since the late 20th century, construction companies have developed different brands of apartments while keeping the LOHAS, well-being, ubiquitous, and one-stop-living concepts in mind. From this point of view, this study intends to define the diverse space planning needs of apartment residents. The purpose of this study is to suggest optimum guidelines regarding the subject of space requirements and planning by conducting in-depth interviews of residents whose apartment floor size is between $66m^2$ (20 Pyong) and $165m^2$ (50 Pyong) and whose apartment is less than 5 years old. The major findings were as follows: (1) The shortage of storage space in different types of apartment housing units was found to be a chronic problem. Thus, closet sizes mustbe increased. (2) The size of the master bedroom needs to be decreased, whereas the size of the kitchen and dining room as well as the size of the second and/or third bedroom must be increased. More space is required in common areas occupied by the family and larger closets are needed. Less space is required for the master bedroom.

This study is planning improvement of welfare facilities about the hall for the aged in apartment housing. An apartment house, famous residential type in Korea, put an important value on its convenience and economical efficiency of furniture arrangement by maximizing floor space index. In this regard, leisure usage of house was not carefully considered for the aged people. To redefine the efficiency of welfare facilities, research mainly deals with analysis of realistic needs for the aged through the spot survey and interview. The main purpose of this study is to enhance the quality of welfare facilities and propose the improved welfare facilities for the aged people. Through the research, conclusions are as followed First, Facility standard and provisions of the law should be revised for considering population growth of the aged people. Second, there are 4 plan types in the hall for the aged. Contrary to our expectation, diversity of program was not found however various program planning is needed for considering its different types of plan. Third, according to regulation, space restriction is based on the number of households. Therefore, room and space standard does not depend on the number of people. From now on, in order to improve quality of welfare facilities of the aged, revision of laws and overall facility standard should be implemented in advance.

This study does try to proceed on the assumption that complex buildings can vitalize urban life of modern society from contemporary complexity and cases of past failure, and intend to propose future planning guidelines and directions of the neighborhood mixed-use buildings in the housing development district of small cities. For this purpose, thirty buildings which had been built on Bugok housing district in Gimcheon from 1999 until 2007 were chosen and investigated in urban and architectural dimension. The scope of this investigation is that site size is below 400 square meter and the number of stories on the ground below 5 floor, and the method of that is through field investigation, field photographs, and recordings and drawings on those. Investigative contents could be divided and analysized into physical and functional elements in urban and architectural dimension. On the basis of these results, the future planning approach of complex buildings in medium and small cities will be considered as planning principles.
