  • This study was designed to investigated children's spatial cognitive skills as based on their practice with computer games. The sixty children were divided into 3 groups there were twenty children in experimental group 1 (the geometric game experimental group), twenty children in experimental group 2 (the arcade game experimental group), and twenty children in the control group. The sSpatial cognitive skills of the children were assessed according to by visual speed, mental rotation, and spatial visualization tasks. The rResults showed that computer game practice enhanced the children's spatial skills (visual speed, mental rotation and, spatial visualization). The c Children's mental rotation and spatial visualization showed a significant difference with the type of computer game.

  • The development of contemporary spatial structures for long-span roofs in China was initiated in the 19505. Space trusses, reticulated shells and cable suspended structures have been developing rapidly since 1980s. Recently there has been a growing interest in tensile membrane structures. Comprehensive theoretical study has been carried out parallel to the engineering application, which provided necessary theoretical support to the development of different types of spatial structures.

  • Spatial structures have the different dynamic characteristics from general rahmen structures. Therefore, it is necessary to accurately analyze dynamic characteristics and seismic response of spatial structure for seismic design of spatial structure. An arch structure is used as an example structure because it has primary characteristics of spatial structures. Multiple support excitation may be subjected to supports of a spatial structure because ground condition of spatial structures is different. In this study, the response analysis of the arch structure under multiple support excitation and simple support excitation is studied. By means of the pseudo excitation method, the seismic response is analyzed for long span spatial structure. It shows that the structural response is divided into two parts, ground displacement and structural dynamic response due to ground motion excitation. It is known that the seismic response of spatial structure under multiple support excitation and simple support excitation are the different in some case. Therefore, it has to be necessary to analyze the seismic response of spatial structure under multiple support excitation because the spatial structure supports may be different.

  • A retractable-roof spatial structure is frequently used for a stadium and sports hall. A retractable-roof spatial structure allows natural lighting, ventilation, optimal conditions for grass growth with opened roof. It can also protects users against various weather conditions and give optimal circumstances for different activities. Dynamic characteristics of a retractable-roof spatial structure is changed based on opened or closed roof condition. A tuned mass damper (TMD) is widely used to reduce seismic responses of a structure. When a TMD is properly tuned, its control performance is excellent. Opened or closed roof condition causes dynamic characteristics variation of a retractable-roof spatial structure resulting in off-tuning. This dynamic characteristics variation was investigated. Control performance of a passive TMD and a smart TMD were evaluated under off-tuning condition.

  • Little research has been done regarding the explicit and objective analysis and explanation of the spatial logic of traditional Korean settlement patterns, in spite of many archeological and socio-historical studies. In this paper we present research into spatial mechanisms and their social meanings in three traditional villages in the southern province of Korea. Conventional space-syntax analysis of spatial configuration has been used to analysis and investigate the morphological forms and functions of the traditional villages. The research results show that the traditional Korean villages are spatially deeper and syntactically less connected than other comparable urban forms, such as old European cities. Configurational analysis of the three villages reveals that their spatial structures are configured to have their own spatial logic, not a geometric order but a spatial structure. What is however noteworthy is the way they embrace their own environmental context and factors and implement them into the process of urban growth or spatial construction.
