Recently, grafting of a story into a game has attracted ever increasing attention. In this study, the 12 phases of Hero's Journey by Joseph Campbell highlighted in movies and myths was analysed from a point of Christoper Vogler to be correlated with a game. Since a story-teller Is a player in a game, the story experienced by the player enjoying the game was examined and correlated with the 12 phases of Campbell. As the game, a construction/management simulation game, RCT3 produced by Atari was studied. The 12 phases of Campbell was applicable to game story.

The seismic isolation system reduces the seismic vibration that is transmitted from foundation to upper structure. This seismic isolation system can be classified into base isolation and mid-story isolation by the installation location. In this study, the seismic behavior of arch structure with mid-story isolation is analyzed to verify the effect of seismic isolation. Mid-story isolation is more effective than base isolation to reduce the seismic responses of roof structure. Also, this isolation would be excellent in structural characteristics and construction.

This study examined and analyzed locational conditions of apartment houses in regional small cities to provide basic materials to set direction and index of view management of apartment house and thus the results of the study are as follows. 1. The number of story of apartment houses 'below five story' was 48% and area of apartment house was 'over 500m$^2$ and below 1000m$^2$' in 31% of the whole regions. 2. As a result of analyzing correlations with changes of floor of apartment house by construction year, apartment houses below 10 story were mainly built between 1991 and 1995 and high-storied apartment houses over 11 story were mainly built since 1995 and apartment houses over 21 story were built since 2000 and these high-storied apartment houses were main cause of hindering view of small cities. Accordingly, establishment of guideline of building high-storied apartment house which can be a primary obstacle of urban view and regulations of height are needed.

In the previous comparative studies of international competitiveness conducted before 2003, Korean construction productivity had been estimated to be lower (or poor) than that of developed countries such as US, UK, and Japan. However, the amount of international contracts Korean has won increased substantially, and Korean construction has progressed with creating two skyscrapers such as Petronas Tower and Burj Dubai. At this point we need to reevaluate what we are capable of. In this paper, we evaluated international competitiveness of our construction industry comparing to advanced countries by analyzing labor productivity. For evaluating construction competitiveness we measured labor productivity using the value of construction work in US dollar per hour based on domestic and foreign statistical data and analyzing completion days per a story and the ratio of underground floors to ground floors of buildings in Korea and Japan. As a result, although our construction productivity is not yet competitive with the US and Japan yet, we excel the UK.

Recently, two unique high rise buildings have been designed and constructed in Korea. The two buildings, which consist of mega braces and mega columns, are 70-story, 105-story high rise buildings. Through two external structural frame systems, it will be analyzed mechanical and structural characteristic mega column and mega brace system in this report. Particularly, the joint has been studied through the analytical method based on the load transfer mechanism at the point where a mega brace and mega column meets.

In underground parking lots of apartment housing, the story height is increased by $300{\sim}400mm$ because of various ducts for HVAC. In order to reduce this story height, this study proposed the 'hybrid beam', which is composed of PC beam with embedded steel beam and insitu concrete. The depth of the hybrid beam is reduced by 300 mm and then the steel beam is embedded over the length of reduced depth to compensate for the loss of strength. Then, we performed the large-scale structural tests on 9 specimens and investigated the flexural behavior of the specimens. The parameters of tests were the shape of steel beam section, the length of the reduced depth, the stage of construction, the effects of slab and shear connectors. The test results showed that the specimens, after the insitu concrete has cured, has the flexural capacity which exceeds the required design capacity regardless of other parameters. On the other hand, the specimens of construction stage do not have sufficient strength. Based on these results, it is thought that the proposed hybrid beam with reduced depth is applicable to the underground parking lots of apartment housing as long as the support is placed at construction stage.

Structural analysis and design of steel frames is usually conducted under the assumption that beam-to-column connections are either fixed or pinned. In reality, each connection possesses a certain rotational stiffness. In this study, structural analysis program is developed, which takes into account the nonlinear behavior of framed structures including flexibility of semi-rigid connections and member geometric nonlinearity. Effective semi-rigid connections for a 6-story unbraced steel frame are suggested and the effect of flexible connections on the behavior of the structure are studied.

This study proposes a method of generating steel house shop drawing in an automated design method, reducing construction manpower and period. With one hour fire-resistant approval code, reflecting work ability and efficiency, steel-framed house market is expected to extend from one or two story house to multi-purpose facilities up to four story height. More models have been constructed in this system than the first appearance of fire-resistant approval in Korea in 1997 Also, cost estimation of components such as frame walls, roof trusses and floors is obtained with shop drawings. Also, the lack of suppliers of steel framed house shop drawing and unstandardized drawing method get constructors have difficulty in understanding its design. In steel framed house industry, shop drawings are essential part in building and constructing framework and they have major effects on construction deadlines and expenses. By exploring method of shop drawing automation, this study aims to optimize work flow with a standardized drawing method. The proposed system can be applied to manufacturing automation in domestic industry of factory-built panelizing method in the near future.

Almost all building/infrastructures made of composite materials are fabricated without proper design. Unlike airplane or automobile parts, prototype test is impossible. One cannot destroy 10 story buildings or 100-meter long bridges. People try to build 100-story buildings or several thousand meter long bridges. In order to realize "composites in construction", the following subjects must be studied in detail, for his design: Concept optimization, Simple method of analysis, Folded plate theory, Size effects in failure, and Critical frequency. Unlike the design procedure with conventional materials, his design should include material design, selection of manufacturing methods, and quality control methods, in addition to the fabrication method.on method.

Recently, the regulation about HEE(horizontally installed emergency exit) established at upper 4story in apartment houses was introduced by revising enforcement degree of Building Act. HEE is a facility for egress to lower story through floor breach and ladder system so that it gives a useful evaquation way directly to an individual household in apartment when they failed to evacuate through the entrance door. HEE may offer an opportunity to optain two way egress path ways instead of evacuation space at balcony and through path way to adjacent household in building and that might be an big strengh. but it needs to guarantee for against the crime, getting detailed reviews for being security and supplementation of fire test methods.
