This study is aimed to propose the evaluation model of forecasting visual quality of apartment buildings, which would be a useful tool to make the architectural concepts corresponding to user needs. This study was carried out through the four-step experiments as follows. The first step is to take the user's visual evaluation construct. To do this, the 22 adjective phrases were extracted, which were applicable to all apartment buildings. The second step is to analyze the user's visual preference, which is measured by the user's psychological quantity on the apartment buildings by S. D.(Semantic Differential) Method. The third step is to analyzethe five psychological-factors obtained from the Factor Analysis. The perceptual images on the 41 experimental subjects were checked up through evaluating and analyzing the factor scores of each subjects for each psychological-factor. The fourth step is to analyze, the similarity of various characters in a building, which is mirrored on the user's psychological quantity and how buildings are grouped by it.

This study is a understanding on technological specific expression to reflect of a research institute in modern architecture. For this study, it separately reduce space program, plan program, design elements of elevation, structural system, mechanical system, building material program to its expressional elements of research institute. Also, it's arranged about a specificity that is expressed for technology each plan elements of a research institute. As a result, elements what is expressive of technology on research institute are influenced an aesthetic expression, expression of an arrangement system, structural expression, expression of architectural organization, and it influences more getting feels technological specificity expressed an aesthetic, structural system, architectural composition, mechanical distribution system in order of their magnitude. This is offered suggestion what must be an achievable complex both a simply technological expression and aesthetic expression.

104 village has kept the landscape of low-income settlements at hillside village as called 'Daldongnae' since 1960s. It has high urban and social values in modern housing history of Korea. This study is to analyze the basic type, transformed type of street facade and also the meaning in the modern housing history. It analyzes basic elements(building elevation, gate, fence) and subsidiary elements(roof form, door, window), and the type of street facade by the composition of the element.

The purpose of this research is to design a road using digital photogrammatry method to generate DEM(digital elevation model) and digital ortho image based on GSIS which was applied to the road simulation. The example study area was the suburbs of Jeju city. To this study, 1/5,000 digital map and GSIS technique were used for optimum road design of the island based on Arc View software. Using this software we can Set an overlay map by combination of hill shade map, slope map, aspect map, and building buffer map. Based on this overlap map, we designed the best road line and along this line we performed three dimensional road simulation using Microstation CAD and Inroads road design programs. From the results, we found that the DEM and digital ortho image acquired from stereoairphoto using digital photogrammatry was satisfied for choosing the best roadline and the developed three dimensional road simulation technique using GSIS technique was very useful to estimate the reasonable road design before the real road construction works.

This paper presents a simplified model to study post-buckling behaviours of the axially restrained steel column at elevated temperatures in fire. The contribution of axial deformation to the curvature of column section is included in theoretical equations. The possible unloading at the convex side of the column when buckling occurs is considered in the stress-strain relationship of steel at elevated temperatures. Parameters that affect structural behaviours of the axial restrained column in fire are studied. The axial restraint cause an increase in the axial force before the column buckles; the buckling temperature of restrained columns will be lower than non-restrained steel columns. However, the axial force of a restrained column decreases after the column buckles with the elevation of temperatures, so make use of the post-buckling behaviour can increase the critical temperature of restrained columns. Columns with temperature gradient across the section will produce lower axial force at elevated temperatures.

Laser scanning has become a viable technique for the collection of a large amount of accurate 3D point data densely distributed on the scanned object surface. The inherent 3D nature of the sub-randomly distributed point cloud provides abundant spatial information. To explore valuable spatial information from laser scanned data becomes an active research topic, for instance extracting digital elevation model, building models, and vegetation volumes. The sub-randomly distributed point cloud should be segmented and classified before the extraction of spatial information. This paper investigates some exist segmentation methods, and then proposes an octree-based split-and-merge segmentation method to divide lidar data into clusters belonging to 3D planes. Therefore, the classification of lidar data can be performed based on the derived attributes of extracted 3D planes. The test results of both ground and airborne lidar data show the potential of applying this method to extract spatial features from lidar data.

The monorail system as new transportation system mostly has being constructed as an elevated construction. In particular, in case of construction to elevated structure in the center of a city, it is important to decision for a monorail station to be considered the minimization. We must purchase the required lands prior to design the monorail stations because of separation of a platform and a waiting room. So We can exclude the problem that it have too close between a monorail station and the other building. Therefore the standard width and elevation of the monorail station shall be considered the efficient execution, economic and transportation. We have many thing to resolve as the plan of minimization to the station of monorail. But we know the ultimate in environmentally friendly transportation, of course, is our monorail system and we are positive as to a popular transportation craze.

As one of the most important vertical transportation equipment in super high-rise buildings, the construction elevator directly affects the project period, cost, and effectiveness. The paper proposes a new construction elevator with single-guide rail and multi-cages. It can solve the problems of single construction elevator capacity shortage and efficacy decrease with height reduction, the occupancy of plan and elevation position of multiple construction elevators, and extension of total construction period by cycling operation of multi-cages on a single-guide rail. The paper focuses on the design and research of the main components of the equipment, such as the rotating guide rail mechanism, vertical bearing mast tie system, segmented electrical power supply system, group control scheduling system, and safety anti-collision system.

This study is related to excavation from ruins the memorial structure within the Jeongreung royal tomb. There are experimental assertion on the basis of results of the excavation, historical records. The location of the memorial structure is identified in picture of Sunwonbogam(선원보감), records of Chunkwantongho(春官通考). The memorial structure have 6 rooms where lay in 250 steps(步) from the south of Hongjeonmun gate, lotus pond lay in southeast of the structure recorded on Chunkwantongho that's guide book to manners. It's matched in the location as result of excavation. The building site consists of main house(윗채), outhouse(아래채) that's stationed in stepped. It seems that main house as the memorial structure have 6 rooms. It's used as outhouse for facilities attached to the main. It's characterized the memorial structure within the Jeongreung royal tomb that's stationed main house, outhouse in stepped it using natural ground. It's estimated that it's tried to conservation for building site, fence etc. in next several time. With regard to constructing time of the structure, traces involved to first construction is simple: 2 chimneys in flower bed, fence, a part of stone elevation, drains by using rectangular stone. It shows that the building site had been reconstructed or renovated during Gho-jong King 37s year of the Choson dynasty(A.D.1900). It seems that the memorial structure during approximately 300 years in existence from Hyeon-jong King 10s year of the Choson dynasty(A.D.1669) to the late 1960s.
