  • The role of cost modeller is to facilitate the design process by systematic application of cost factors so as to maintain a sensible and economic relationship between cost, quantity, utility and appearance which thus helps in achieving the client's requirements within an agreed budget. There are a number of research on cost estimates in the early design stage based on the improvement of accuracy or impact factors. It is common knowledge that cost estimates are undertaken progressively throughout the design stage and make use of the information that is available at each phase, through the related research up to now. In addition, Cost estimates in the early design stage shall analyze the information under the various kinds of precondition before reaching the more developed design because a design can be modified and changed in all process depending on clients' requirements. Parametric cost estimating models have been adopted to support decision making in a changeable environment, in the early design stage. These models are using a similar instance or a pattern of historical case to be constituted in project information, geographic design features, relevant data to quantity or cost, etc. OLAP technique analyzes a subject data by multi-dimensional points of view; it supports query, analysis, comparison of required information by diverse queries. OLAP's data structure matches well with multiview-analysis framework. Accordingly, this study implements multi-dimensional information system for case based quantity data related to design information that is utilizing OLAP's technology, and then analyzes impact factors of quantity by the design criteria or parameter of the same meaning. On the basis of given factors examined above, this study will generate the rules on quantity measure and produce resemblance class using clustering of data mining. These sorts of knowledge-base consist of a set of classified data as group patterns, of which will be appropriate stand on the parametric cost estimating method.

  • Recently, as a performance based design concept is introduced, assurance of expected performances on serviceability and safety in the whole span of life is exactly requested. So, quantitative assessments about durability related properties of concrete in early-age long term are come to necessary, Especially in early age, deterioration which affects long-term durability performance can be occurred by hydration heat and shrinkage, so development of reasonable hydration heat model which can simulate early age behavior is necessary. The micor-pore structure formation property also affects shrinkage behavior in early age and carbonations and chloride ion penetration characteristic in long term, So, for the quantitative assessment on durability performance of concrete, modelings of early age concrete based on hydration process and micor-pore structure formation characteristics are important. In this paper, a micromechanics based hydration heat evolution model is adopted and a quantitative model which can simulate micro-pore structure development is also verified with experimental results. The models can be used effectively to simulate the early-age behavior of concrete composed of different mix proportions.

  • The purpose of this study is to suggest a methodology to grasp the design method of industrial slacks pattern for women in their early twenties. The result of this study is as follows: 1. The result of the questionnaire showed that the design of rear center gradient was most important and the rear center gradient was designed by shifting waist line and hip line to a suitable degree.; below the waist by 4cm, the girth was measured and the ease of $0{\sim}1cm$ was applied to it, and the ease of hip girth was $3.2{\pm}1.2cm$, and rear center gradient was $2.2{\pm}1cm$, and front crotch extension was $2.8{\pm}0.5cm$, while rear crotch extension was $6.3{\pm}0.5cm$. 2. By comparing rear center gradient which was selected as an important design item with total crotch length and hip girth, I selected industrial pattern and educational pattern, and evaluated them on human bodies. In the result of ANOVA analysis, there were meaningful differences in 8 items: the ease of front waist girth, the ease of front abdomen, the ease of front hip girth, rumples in the side lines, the location of rear waist line, etc. 3. The design method of slacks pattern suitable for women in their early twenties was suggested as follows: the location of waist girth is below waist by $2.5{\sim}3cm$; the ease of waist girth is $0{\sim}1cm$; the ease of hip girth is $2{\sim}3cm$; total crotch length is body size - 5cm; rear center gradient is $2.5{\pm}0.5cm$; rear crotch extension is $7{\pm}0.5cm$; front crotch extension is 3cm.

  • The purpose of this study was to examine whether the intergenerational program affected the children's perceptions on the elderly and aging. This study also investigated how the children evaluated the program. The study methods was one group pretest-posttest design. The subjects were 30 elementary school children from 1st to 3rd grade. The intergenerational program was composed of 6 activities: recreation activity for rapport, making a kite, gardening, learning old customs, education of traditional manner, and making rice-cakes. It was executed for two weeks. Data for children's perceptions on the elderly and aging were collected by the interview using questionnaire at pretest-posttest. The results of the qualitative data analysis showed that the children's perception on the elderly and aging changed more positively after the program. There were significant differences between pre- and post-test on the children's perceptions of aging and intellectual aspects of the elderly. Most of the children evaluated the program very positively.

  • Various computer-based simulation tools such as 3D-CAD and CAE systems are widely used to design automotive body structure at the early phase of design. Designers must search the optimal solution that satisfies a number of performance requirements by using their tools and a trial-and-error approach. In the previous three reports, a set-based design approach has been proposed for achieving design flexibility and robustness while capturing designer's preference, and its effectiveness has been illustrated with a simple side-door impact beam design problem and real vehicle side-door structure design. This report presents the development of integrated 3D-CAD and CAE system, and the applicability of our proposal for obtaining the multi-objective satisfactory design solutions by applying to an automotive front-side frame.

  • These days, shipbuilding companies are making an effort to adopt the IT technology in order to improve the production efficiency. One such effort is to utilize a planning and scheduling system to predict the production cost in advance. In this system, assessing the welding material quantity is an important factor. Unfortunately, obtaining the welding material quantity in the early design stage is extremely difficult because the detailed production information, which is essential in deriving the cost associated with welding, is normally available at a later stage. This paper aims at developing a computerized program that produces an index to estimate the welding material quantity in the early design stage. By using only three-dimensional geometric information, the program analyzes the production process and estimates the welding material quantity at any design or production stage when no production information is available. The results can be used for the planning and scheduling system.
