This design is for the landscape of Busan Yeonje Post Office. The design requirements were: the preparation of an open space, the expression of regional identity, total design concept, and application of environmentally-friendly materials. The Busan Yeonje Post Office is not a just post office building but also a place for people including a communications center, rental offices, and a post office, facilities which require publicity, functionality, and symbolism. Therefore, this design reflected the design requirements, and considered the following to include the theme of "Pleasant messages and a pleasant post office with vitality and comfort. First, the open space was to be increased in the adjacent public vacant lot and street park by pulling back the construction line. In this way, the publicity, accessibility, and spatiality of the prepared open space were strengthened. Second, a sense of place for the landscape was expressed through the image of a wave representing Busan, a coastal town. Recognition of the space was strengthened, while regional identity and the concept of transmission of information were expressed. In addition, Citrus junos Sieb., representing 'Happy news' was Planted as a symbolic tree to denote a meaningful resting Place. Third, with respect to the design of reception facilities, considering the general purposes of the construction, post office stamps, envelopes, and postal delivery persons were portrayed on the walls, decorative walls, and environmental formations respectively The flooring was decorated with stamps and waves in keeping with of the total design concept. Fourth, to select environmentally-friendly materials, soil block and eco-grass block were introduced as major paving materials, and folk kinds of trees were included on site. According to the aforesaid plans, the researcher attempted to convert the public agency and office space characterized by feelings of dullness and rigidity into a soft and vivid outdoor space. It is expected that the location will be an open place in the downtown area and be recognized as a 'shared' space for citizens of Yeonje-gu.

This study is aimed to personally measure the body of physically handicapped women and compare the measurements to the results of the fifth project to investigate the measurements of the body of Koreans, identity the differences in the measurements in accordance with the subjects' handicap types and age, and find the characteristics of their physical figures, with a view to propose basic data for developing clothes suitable to the body of physically handicapped people. The findings of this study are summarized in the following: 1. There were significant differences in the measurements of the subjects' shoulder width, breast circumference, waist circumference, hip circumference, armpit circumference, left and right upper arms' circumference, length between front walls of the armpit, and length between back walls of the armpit after the subjects' handicap types were classified into paralysis of the lower half of the body, cerebral apoplexy, cerebral palsy, and amputation and the differences in the subjects' bodily measurements were compared and analyzed. 2. The shoulder width gradually increased for those in their 50s or younger while that of those in 60s or older is almost the same as that of those in their 30s. The waist circumference gradually increased in all the subjects. As a result, the present author concludes that the body of physically handicapped women increases the same way as the body of ordinary adult women does in its circumferential measurements as the subjects grow older.

International Convention Center Jeju(ICCJ) was planed and built for accommodating a variety of conventional and exhibitional activities. For a better flexibility of operation, almost all rooms in ICCJ are designed to be subdivided Into a couple of small rooms with installation of movable partition walls. Architectural and acoustical design should be deliberatively and cooperatively undertaken to cope with such a complex condition. Conference hall, the largest room in ICCJ, has a capacity of 5000 seats who:1 used as a whole. It could be divided into 3 halls, one with 2000 pre-installed seats on slanted floor, up/down removable stage and its settings above, and the other 2 flat rooms with no seats installed. A devided hall with pre-installed seats and stage is designed for a multi-use auditorium. Almost all surfaces except ceilings adjacent to the stage are sound absorptively treated, in regard to extensive use of sound reinforcement systems. Its reverberation time 1.65 sec without audience, which is roughly correspond to 1.50 sec with fully occupied audience. When there is a need for a larger room, all the partition wail Is removed and the hall could be used as a whole. Exhibition hall is located in the first floor of ICCJ. Absorption and softness are needed for the hat 1 because exhibition behavior has something noisy features. Perforated MDF panels with porous materials and air space in the back groundare adopted for the walls. There are one large, two medium, and several small convention rooms in ICJJ. The room are also acoustically designed for maximum flexibility with no defects soundwisely.

Thinned, small larch logs have small diameters and no value-added final use, except as wood chips, pallets, or fuel wood, which are products with very low economic value; however, their mechanical strength is suitable for structural applications. In this study, small larch logs were sawed, dried, and cut into square timbers (with a $90mm{\times}90mm$ cross section) that were laterally glued to form core panels used to manufacture cross-laminated timber (CLT) wall panels. The surface and back of these core panels were covered with 12-mm-thick structural plywood panels, used as cross bands to obtain three-ply CLT wall panels. This attachment procedure was conducted in two different ways: gluing and pressing (CGCLT) or gluing and nailing (NGCLT). The size of the as-manufactured CLT panels was $1,220mm{\times}2,440mm$, the same as that of the plywood panels. The final wall panels were tested under lateral shear force in accordance with KS F 2154. As the lateral load resistance test required $2,440mm{\times}2,440mm$ specimens, two CLT wall panels had to be attached in parallel. In addition, the final CLT panels had tongued and grooved edges to allow parallel joints between adjacent pieces. For comparison, conventional light-frame timber shear walls and midply wall systems were also tested under the same conditions. Shear walls with edge nail spacing of 150 mm and 100 mm, the midply wall system, and the fabricated CGCLT and NGCLT wall panels exhibited maximum lateral resistances of 6.1 kN/m (100%), 9.7 kN/m (158%), 16.9 kN/m (274%), 29.6 kN/m (482%), and 35.8 kN/m (582%), respectively.

Recently, the size of tiles used for bathroom walls in apartment houses is gradually increasing in size. The problem is that when these large-sized tiles are attached by the sticking method, due to the nature of the method, there is a concern about the stability of the attachment to the part (pupil) where the tile and the adhesive are not attached. The problem is serious as it leads to lawsuits in the outbreak court. In addition, it is urgent to verify the adhesion stability of the sticking method because secondary damage occurs due to a safety accident caused by the falling of the tile. Ministry of Land, Infrastructure and Transport [Investigation of defects in apartment houses, calculation of repair cost and defect determination criteria] ① The tile adhesion strength is 0.39N/mm² or more and ② It is specified to fill 80% or more of the base area of the tile backside, but this is currently trendy. It is considered that large-sized tiles need to be verified from multiple angles, and as part of that, we intend to verify the adhesion stability according to the area to be attached to large-sized tiles.

This paper presents the results of investigation on the effects of foundation stiffness and surface loading on the performance of soil-reinforced segmental retaining walls using the finite element method of analysis. A parametric study was performed by varying the foundation stiffness and the location of surface loading. The results of the analyses indicate that the wall deformation and reinforcement tensile load tend to increase with decreasing foundation stiffness with little variation in the horizontal and vertical stress distributions at the back and the base of the reinforced soil zone. Also revealed is that the increment of reinforcement tensile load due to the presence of surface load may be significantly over-estimated when using the conventional approach. Furthermore, the external stability should be carefully examined when a surface loading is present just behind the reinforced soil zone. The implications of the findings from this study to current design approaches are discussed in detail.

This study examines potential growth and different perspectives on green-walls, which are being re-evaluated recently. The aim is to identify the viewer preferences concerning the walls by collecting a wide spectrum of information to create an interior design related comprehensive and intellectual database. Also based on this proposition, choosing a green surface of indoor wall as a specific example stimulus, identifying a relationship betweeationsviewer's preference factors. The relationship will formulate detailed and absolute qualities, which will reach potential areas that the green walls can be widely applied in. As a result of a factor analysis, the viewers classified into the 3 factors as is pleasant, gorgeous and rich about the stimulus. Preferred key factors, which are closely related to emotional image language, were; cool, tidy, comfortable and beautiful. The common factors in preferred design stimulus, in order of importance are color>elements>image/form/plants. Specific levels of design factors according to relevance are contrast>furniture> modern>central/creeper foliage plants. In the meantime, this study is leading the process of quantitative measurement of green-walls to a new design direction and it is critical to consistently experimenting to back up the theory with solid evidence.

The purpose of this paper is to estimate and deduct appropriate Hanok type within Suwon Hwaseong Fortress in which formula Hanok type has not remained. To do so, urban change according to chronology is analyzed and architectural aspect of transition is collected. By using geographic information in Suwon Hwaseong Fortress, present urban structural density, status of architecture and chronological aspect of transition in one-story buildings is surveyed. Through these data, appropriate Hanok form and density to the area is suggested. As a result, Hanok with two or more stories is economically suitable because its average plottage is excessively narrow. And back trowelling is desirable to construct walls in some concentrated areas with Hanok through arrangement of construction. Also in the other building sites, Hanoks are formed by a standard for separation to the property line. However it is necessary that exist standard about separation of property line is institutionally alleviated.

The structural efficiency of tall buildings heavily depends on the lateral stiffness and resistance capacity. Among those structural systems for tall buildings, outrigger system is one of the most common and efficient systems especially for those with relatively regular floor plan. The use of outriggers in building structures can be traced back from early 50 from the concept of deep beams. With the rise of building height, deep beams become concrete walls or now in a form of at least one story high steel truss type of outriggers. Because of the widened choice in material to be adopted in outriggers, the form and even the objective of using outrigger system is also changing. In the past, outrigger systems is only used to provide additional stiffness to reduce drift and deflection. New applications for outrigger systems now move to provide additional damping to reduce wind load and acceleration, and also could be used as structural fuse to protect the building under a severe earthquake condition. Besides analysis and member design, construction issue of outrigger systems is somehow cannot be separated. Axial shortening effect between core and perimeter structure is unavoidable. This paper presents a state-of-the-art review on the outrigger system in tall buildings including development history and applications of outrigger systems in tall buildings. The concept of outrigger system, optimum topology, and design and construction consideration will also be discussed and presented.

The purpose of this paper is to examine and analyse the features of plan type and space composition of the Siheyuan(courtyard house) which is one of the most remarkable types of the traditional dwellings in China. With the passage of time this house developed into one of the chinese house style. The technique of Siheyuan's spatial composition goes so far back in the New Stone Age. The relics of this are the colony layout, the system of four sides, the layout type of a palace, the picture of lacquered ware, the pictured brick, the earthenware of house type, the cave painting, the paintings of painters and others. The fundamental spatial conception of it arranges one or more courtyards to compose, sometimes in a very complex way, a general walled compound. The main longitudinal axis is mainly north-south, but the chief buildings, or halls are always placed transversely to it. These rectangular buildings mayor may not connect, by means of open galleries variously planned, with rows of smaller buildings flanking the courtyards on both sides. On this system, enlargement is never carried out by adding to height, but by continual duplication of existing units, and growth in breadth or preferably depth. The need for family security is thought to have led to the development of this rectangular houses with walls mainly blank on the outside, defensible entrances, and public service facilities in the center of the houses.
