This paper presents the development of the design of the robot element. Robot element design is an important part of robot design since it decides the performance and life time of the robot. It is necessary that the robot kinematics and the robot dynamics are accomplished to design the robot elements. The robot kinematics and dynamics determine the design parameters of the element. We developed a robot element design program with which a designer can design the robot element with convenience and reliability. The program is composed of motor, harmonic driver and ball-screw design. The program is founded on the virtual robot design program. The virtual robot design program is the powerful software which may be used to solve various problems of the robot kinematics and dynamics. The robot element design program may be used to calculate the design parameters of the element that are necessary to design robot element. Therefore, the designer can decide upon the available robot elements available to perform the objective of the robot. The robot element design program is expected to increase the competitiveness and efficiency of the robot industry.

The objectives of this study are to develope the automatic design programs to offer the data when constructing a small scale vinyl-house by region. This program consists of four subroutines. The first is an automatic greenhouse modeling program, the second is a calculating design load program by region, the third is a structural analysis program and the last is a optimum shape design program. The structural analysis can be conducted by simple date input and considering the design load of the install regions into account. The shape of input data is very simple, and the program reflects the design load by region. The output data can be obtained from the automatical calculation processing after structural analysis. The program was verified by compared with outputs of a common use structural analysis program and the results are the same. It was concluded that the developed program could be used efficiently in optimum design of small scale vinyl house.

In this study, we fill a person's shoes human knowledge use a computer fast and simple repetition in architecture design. this study are launched from a assumption that a optimized arrangement spaces are able to measure and gauge. but automatic space arrangement program is first step, we have a value that propose a differential cell space and valuation space and process of optimized space arrangement. the merits of this design process are as follows; 1. this program has a advantage high the building-to-land ratio land and business area in space design. 2.this program can design a economy building and calculate rent benefit and calculate cost of construction. 3. this program can adapt for digital GIS. this program can down cost in labor productivity. 5. a layman can design high level. the weak point of this design process are as follows; 1. the design product is simple box shape. 2. this program has a weak in large area and complicated land shape 3. complex use space design are difficult in this program.

In the preliminary design stage of Prestressed Concrete (PSC) Box Girder Bridges, the design factors(including depth, thickness of web, and jacking force) decided by inexperience designer could heavily affect the final design factors. So there is a possibility that the design ends up with an excessively wasteful design. To aim at an economical design with preventing an excessive design, the optimal design program has been developed by using ADS optimal program and SPCFRAME(PSC Bridge analysis program) in these studies. The optimal design program automatically calculates economically optimized design studies. The optimal design program automatically calculates economically optimized design factors by introducing the optimal design techniques of PSC box girder bridge design. The objective function for optimal design is material cost of box girder and constrained functions are constituted with design specifications and workability. The optimal design techniques used the Sequential Unconstraint Minimization Technique (SUMT) with performing the optimal design program. In this study, We designed unprismatic section bridge and prismatic section bridge in the same design condition by optimal design program developed in this study. By analyzing the results we suggested the practical form of tendon's layout comparing the optimal desingns on the basis of each tendon's layout.

In this study, Automatic design program creates 3D solid models and constructs them. The method of making assembly model is two. One assembles the element made in automatic design program with hand, the other develops the automatic design program fur creating assembly model. Automatic design program improves the convenience of user. In creating gears, involute curve and Trochoidal fillet curve are made by mathematical development.

This paper presents the development of a virtual robot design program. Robot design requires numerical software, robot solution software and multi-body dynamics software to complete several designs. However using a commercialized software implies some disadvantages, such as the waste of time and money it costs to learn how to use the software. We developed a virtual robot design program with which a user can design a robot with rapidity and reliability. The virtual robot design program is composed of robot kinematics module and robot dynamics module. The program is powerful software which may be used to solve various problems of a robot. The 3D animator and a 2D/3D graph of the program can analyze the design results into visual data. The virtual robot design program is expected to increase the competitiveness and efficiency of the robot industry.

In this study, an in-house program to predict steady state operation of micro gas turbines is constructed using MATLAB. The program consists of two parts: design and off-design simulations. The program is fully modular in its structure, and performance of each component (compressor, combustor, turbine, recuperative heat exchanger and pipe elements) is calculated in a separate calculation module using mass and energy balances as well as models for off-design characteristics. The off-design modules of compressor and turbine use performance maps, which are program inputs. The off-design operation of a micro gas turbine under development was predicted by the program. The prediction results were compared with those by commercial software, and the validity of the in-house program was confirmed.

The purpose of this study is to propose a fashion design creativity convergence education program based on creative thinking that can be effectively used to create a creative fashion design in the fashion education field, and to verify the suitability of this program and its effectiveness in improving creativity. To this end, a fashion design creative convergence program combining divergent thinking and convergence thinking was designed, and an experimental study was conducted among college students in the fashion design department. Creativity evaluation was conducted by evaluating students' creative ability and creativity of fashion design results. In addition, an open survey was conducted to collect learners' opinions on the suitability of the program and the convergence process of divergent and convergent thinking. As a result of this study, it was found that the fashion design creative convergence education program based on creative thinking improves the creative competency of major learners of fashion design and is the learning performance competency in the process of producing creative results. This study is meaningful as it is a basic study that proposes a fashion design education program to foster the creative competency of fashion design majors, and is expected to be used in various ways in the educational field.
