The multipurpose auditoriums in schools are the center of local community and the places of their life-long education. The multipurpose auditoriums are to be open and made available for use by local public as far as it does not interfere with the education of the schools. However, most of them are not open to public on the pretext of management problems while demands of local communities for the opening of the facility is rising. The role of the multipurpose auditorium as the place of physical training and its maximum availability to local community have be taken into account of from its design stage. The location of the auditorium itself has to be close to the main entrance of the school for easy access, its facilities located in one common area, their management and maintenance scheme adopted appropriately but legally, and then security and safety measurement have to be devised. Also, more studies are necessary to propose detail regulations for local sports facilities and to develop their interrelationship and network, in connection with sophistication of school facilities and BTL system.

Precast hollow core slabs (HCS) are technically advanced products in the precast concrete industry, widely used in the last years due to their versatility, their multipurpose potential and their low cost. Using three dimensional FEM (Finite Element Method) elements, this study focuses on the stresses induced by the prestressing of steel. In particular the investigation of the spalling crack formation that takes place during prestressing is carried out, since it is important to assure the appropriate necessary margins concerning such stresses. In fact, spalling cracks may spread rapidly towards the web, leading to the detachment of the lower part of the slab. A parametric study takes place, capable of evaluating the influence of the tendon position and of the web width on the spalling stress. Consequently, after an extensive literature review on the topic of soft computing, an optimization of the HCS is performed by means of Genetic Algorithms coupled with 3-D FEM models.

This research has analyzed factors affecting customers' satisfaction when they use parking lots of big retailers so that, in case of constructing, operating or managing such retailers, proper measures can be come up with. The analysis has been implemented on the basis of survey, and influence factors including entry/exit lamp, parking cars' traffic flow, parking type, pedestrians' movement after parking and safety. Parking lot users' satisfaction has been analyzed by using the Structural Equation Modelling and, as a result of it, in case of a detached or single building, pedestrians' movement flow after parking contributed the most to the users' satisfaction, while, in case of multipurpose complex, parking cars' traffic flow has the most influential factor. It is interpreted that users of a single building put a bigger emphasis on entry to the shop and their way back to the parked area after their shopping while customers of multipurpose complex might have various purposes of visiting the place and there are relatively more cars so that they put more emphasis on traffic counterflow, other cars and pedestrians.

Lately multipurpose dam is required to consider various interests such as quality, ecological environment as well as flood control, water supply, hydropower generation, etc. The objective of this study is to investigation and analysis of water temperature in the areas where there are social conflicts due to cold water outflow. In this study, we monitored water temperature of Juam regulation dam, downstream river, Suncheon bay in a long term period and performed comparative analysis on a change of water temperature in downstream river and Suncheon bay by using three-dimensional numerical mode (EFDC) considering various external factors such as water outflow amount. The result of monitoring and numerical modelling indicates that effects of cold water outflow takes place from april to september. Also effects of the low temperature discharge of dam was complicatedly altered by various factors such as outflow time and amount, weather and tide level conditions etc. The result of this study can be utilized as a basic data for establishing improvement of dam operation plan to minimize negative effects of dam's cold temperature water outflow to downstream river and coastal area.

Recently as the efficiency of meal area in the neighborhood facilities has decreased, the user is not satisfied about the existing meal area quality. There are problems due to crucial administration due to ineffective use of the meal area and the in-charge. So, a new meal system is coming up with one meal form at one place with time wise classification to satisfy the users and owner. In this plan, the meal area at basement 1 of Korea Advertisement Culture Hall is not just the existing meal area but in day it is a restaurant, at night a vacant hall and in the weekend it is a banquet hall. Such a premium meal area designed by developing the meal area that has different usage as per time slot is named as "M-KITCHEN" and we intend to plan in such a way. The complete "M-KITCHEN"consists largely of entrance/ exit, food distribution area, eating area, specialized restaurant, rest area, kitchen, warehouse etc. This area consists again of multimedia street entrance "M-street", food distribution area "M-kitchen", meal area "M-place", "M-plaza", "Wall pond", "Layer deck", specialized restaurant "M-china", "M-shushi", rest area "Gardening".

This study is aimed to examine the characteristics of library space, in which user experiences and social networking are central in its design. Today, a library is a place to provide diverse accesses and experiences to information networks, where various individuals and user groups come and share mutual understanding and experiences. Library users developed social ties and a sense of community through library experiences. As a multipurpose space of a community, a library has the characteristics of urban public space like sidewalks and plazas. The eight case studies of libraries are analyzed from the viewpoint of each factor of library experience, including landscape, sidewalk, and plaza experience. The study drew its conclusions as follows. First, a library is a regional landmark for the users. Thus, it tends to be designed to allow transparency on its surface which introduces inner and outer landscape into the inside of the building. Second, the users experience a library similarly as they experience an urban street where they interface, browse, and interact with people and information. As they interact and share experiences, they develop solidarity and social ties among them. A library is designed to preserve continuity to adjacent streets, which increases accessibility to the building and hosts street activities into the building. Third, a library today is designed to be a flexible open space with information networking as well as community networking which allows library users diverse activities within it. For example, a multipurpose grand stairs in the middle of the main circulation of a building allows the users diverse activities. A large open stack with reading areas gives the users the feeling of an urban plaza where they can move vertically and horizontally. In conclusion, all findings of this study imply a user-oriented design for a library building.

This paper presents a case of community participatory neighborhood park design. The site, Yangji park, is located in Sandang-dong, Dongjak-gu, Seoul and the area is about 1,870m. Neighborhood park is defined as an outdoor space which is close to people´s home and is considered to be their own, because of the residents´ collective responsibility, family association, and frequent shared use. It is a place for pleasant rest area for community, sharing a sense of nature and retaining a sense of tradition and culture which is disappearing in a city. It is related to the daily life of the people near the site and becomes a place to let the community increase dialogue and understanding between people. On the other hand, participatory design is a design in which people participate in the design process. Thus people can understand the project well, present their opinions better, and reconcile conflicts between the different interests of people. This design applied a community participatory design method to design a neighborhood park. The major strategies for participatory design were ´workshop´, ´card game´, ´walking site´, ´interview´, and ´questionnaire´. Eight workshops were performed for the participation design. The major spaces and facilities elected by participants were the ´main entrance plaza´, ´entrance symbol space´, ´children´s ´playground´, ´multipurpose sport ground´, ´grass land´, ´foot-pressure area´, ´spaces symbolizing a rock mountain and an old well´, ´space for youth´, ´a pavilion´, etc. From this selection, design concept alternatives were generated by participants. The aster plan was developed from these design alternatives with the help of landscape architects. It was revised by ist visits and community discussions. People were also involved in the construction process and left their own works, such as hand prints, on the site. After construction, residents continued to maintain the park by themselves. As a result, It was found that participatory design was very effective for people´s satisfaction and sustainable park management. By involving people more in the process they developed a sense of community, a sense of ownership, and attachment to the place. In conclusion, it is suggested that we need to develop an effective people´s participation method to Korean society.
