There is a great difference in mechanical behavior between design model one-time loading and step-by-step construction process. This paper presents practical computational methods for simulating the structural behavior of long-span rigid steel structures during construction processes. It introduces the positioning principle of node rectification for installation which is especially suitable for rigid long-span steel structures. Novel improved nonlinear analytical methods, known as element birth and death of node rectification, are introduced based on several calculating methods, as well as a forward iteration of node rectification method. These methods proposed in this paper can solve the problem of element's 'floating' and can be easily incorporated in commercial finite element software. These proposed methods were eventually implemented in the computer simulation and analysis of the main stadium for the Universiade Sports Center during the construction process. The optimum construction scheme of the structure is determined by the improved algorithm and the computational results matched well with the measured values in the project, thus indicating that the novel nonlinear time-varying analysis approach is effective construction simulation of complex rigid long-span steel structures and provides useful reference for future design and construction.

Functional, aesthetic and symbolic working uniforms in the industrial complex are demanded by employees and employers. The purpose of this research was to find out the actual wearing condition and preference of the working uniform design in the industrial complex. The research selected 7 enterprise subjects located in the Changwon National Industrial Complex and adopted a questionnaire method. 912 workers categorized into 4 work groups according to their work posts replied in total. The data and the degrees of satisfaction/preference of the working uniforms were analysed into descriptive statistics and F-tests by using the SPSS S/W package. The results were as follows: First, the style of the working uniform was the standard two-piece style. Second, the degree of the satisfaction with the entrepreneurial image implied to the working uniform was 2.83 throughout the 5-scale evaluation. In addition, the degree of the satisfaction with the working uniform colors was in between 2.94 and 2.96. Third, unsatisfied parts of the upper and lower uniform garments were: sleeve > pocket > collar; and waist belt loop > hip pocket > hem line respectively. Fourth, beige was the most preferred color for the working uniform top and bottom both. The most preferred color images were the calm and safety and the bright and light in order. Especially, the demand on the safety factors and soil proof colors of the outside field workers was much higher than the clerical workers. Fifth, the blouson type jacket with shirts collar or soutien roll collar was more preferred to than the casual style; and the straight formal pants were more preferred to than the casual/sweat sports pants styles. Sixth, inner pockets to keep the mobile phone and pens were required for upper garment details specially by manufacture workers. Increase of the waist belt loop numbers was required by all work groups.

The purpose of luminance measurement in lighting design of urban scale is to prevent light trespass and light pollution, caused by over-bright. Specially, the illumination of road, tunnel and sports complex as urban infrastructure is measured by international standard for illuminance and luminance. It has been used the spot luminance meter and the image photometer to define the characteristics of qualitative and quantitative in exterior lighting. This study introduced the concept of HDR Image, procedure of HDR Image creation and analysis. Applications of HDR Image, particularly within the apartment building exterior lighting design analysis, have been demonstrated. The procedure proposed in this study is a affordable method that is useful for the assessment of luminance distribution in the scene with electric light. It also provides a measurement capability with the high resolution luminance data within a large field of view efficiently and quickly, which is not possible to achieve with a luminance meter.

Owners, local autonumous entities, have a burden on operating project for the lack of their management capacity such as specialty and human resources. In this reason, they want to perform project with CM methods. But there have been only a few case of CM operation and application in a huge construction project. The complex formations of CM and responsible management are used in those project. This situation originates in the lack of CM specialist. Because the CM service used in those case is generally performed as the mixture of responsible management service and design management service, it is not the prototype of CM. The purposes of this study are to present the solutions to the problems concerned with the design development phase management, design phase VE, the application of Fast-Track, PMIS operation and CM execution, etc, and establish the plan to perform CM services efficiently in the public sector through analyzing the case of CM application in Gwangjin-Gu Culture & Sports Center.

The purposes of this study were to summarize the concept of well-being and well-being apartment, to grasp the present condition of apartments which were introduced with well-being elements, and to find out the consumer preferences on well-being elements for apartment planning. Library and internet surveys were performed to summarize the concept of well-being and well-being apartment and to grasp the present condition of apartments which were introduced with well-being elements. Questionnaire survey was carried out from 2nd to 22nd of June 2005, to investigate the preferences on well-being elements for apartment planning. The respondents were 250 residents who are from thirties to fifties and living in urban area. As results, respondents think that 'living for health of body and mind' about concept of well-being and 'certificated apartments by green building rating system' or 'apartments introduced ecological factor' about concept of well-being apartment. They answered that 'yes' about 'Do you have intention to buy well-being apartment?'. The elements in aspect of complex planning having the preference were revealed that promenade for complex design, ecological garden or walking space for landscape design, outdoor exercise space for outdoor design, and security system for foundation equipment. The elements having the preference in aspect of public facilities were fitness room for sports & health facility and study room for cultural facility. The preferred elements in aspect of building and unit design were roof garden for building design, multi-functional room for unit floor plan, natural surface material for interior surface, ventilation system for indoor environment, control system for home automation, and food waste machine for home electronics.

NVH issue at idle condition is one of the major concerns of Passenger and Commercial Vehicle including Sports Utility Vehicle Especially steering wheel vibration at idle condition is a very complex problem and affected by firing frequency of the engine, stiffness of a steering wheel system and the body to which the steering wheel system is attached. To avoid vibration mode coupling between each system of a vehicle, experimental and analytical method has been used at the pre-prototype stage. The resonance frequency of the body and the frame has been decoupled by CAE and the resonance frequency of steering wheel system has been set in between the 1st bending frequency of body and frame. These Results has been used as design guidelines tot the prototype drawing stage. The experimental verification of tile modified pre-prototype vehicle shows good results of the vibration mode decouple. Modal test of prototype vehicle also confirms the vibration mode decouple between each system.

Fitness center which was first introduced through hotel fitness has been disseminated into country over the years and these days it becomes a public sports facility that is available even in a small city. Fitness center usually requires a space more than 500 pyeong and even in a small fitness facility at least 200-300 pyung is in need. Also, complex structure including a space for preparing exercise and other subsidiary facility is necessary as well as various service areas to perform various exercise programs. In case of domestic fitness centers, however, proper standard and data required to compute the scale of each service area is not available due to the short of piling data. Therefore computing each space totally depends on an instinct decision of a designer or client, which may cause the fail of effective use of space. This paper aims to calculate appropriate use of space, that is, the over all space, equipment size, and movement line of each area as well as preference and frequence of use among areas is estimated in order to apply those data when computing appropriate estimation of scale.
