Recently industry has moved towards automated operations with the goal of achieving better product quality greater productivity and reliability The pump design in characterized by extensive utilization of the related database which contains performance data. The inputs to the system are through interactive dialogue sessions and the basic input consist of flow rate, head, of fluid efficiency and the customer special requirements. These basic inputs along with the numerous rules in the knowledge bases and the mathematical modeling enable the effective design of the pump industry This paper represents the development of an automatic pump design system that was composed of a main program the data input module the drawing module the drawing edit module and was programed by the AutoLISP language under the Auto CAD program The developed system ultimately generates the design for a pump through the AutoCAD language.

For a good design, it is important to understand consumers and trend of textile and fashion design. Previous researches on textile pattern design with CAD have been done. They have studied on Korean traditional floral motives/hand painting or some geometric patterns. Few studies have been done on conversational design. Therefore the purpose of study was to observe types of textile pattern design for the recent fiver years and determine fabric pattern trends, especially on the conversational motifs. The types of patterns were analysed with professional panels from the 2005～2009 collection sources, using SPSS program. This study was also develop textile patterns creating using CAD. We conducted design process on motif creating, repeat, and mapping jobs, using textile special design program Prima vision and Photoshop CS3.

Free Cantilever Method(FCM) is one of the most effective construction methods when precast prestressed concrete box girders are erected in the construction site. The special feature of FCM is that precast segments are erected in cantilever on the pier and connected in the middle of span to form the complete superstructure. Therefore each structural subsystem will be shown in each construction step and it should be analyzed for design whenever the segment is erected. In this study, the computer program was developed to optimally design the P.C box girder bridge considering tile construction sequence and verified by comparing the calculated results with the data of existing P.C box girder bridges. the sensitivity analysis was performed to show the efficiency of the developed program.

초고층 건물이라는 특수 장소에서 화재가 발생하였을 경우에 야기될 수 있는 제반 문제점을 도출하여 인적, 물적 피해를 최소화하기 위해서 초고층 건물 내에 존재하는 잠재위험요인을 찾아내 위험이 얼마나 큰가를 분석하여 그 해결 방안을 모색하여야 한다. 예방적 측면에서 화재예방활동을 통하여 화재의 발생을 억제하거나, 진압적 측면에서 화재발생과 동시에 초기 진화하는 것이겠지만, 화재의 진행과정을 미리 예측하거나 진행경로를 차단하는 인텔리젠트 또는 파이어 그리드를 이용한 과학소방적 진압방안의 도입이 필요하다.

Success in new product development is vital to most industrial firms. In recent decades, a firm's new product strategy is incresinglyrecognized as an essential component of the total corporate plan in developing countries. In this research, 81 Korean manufacturing firms are examined to identify the relationships between a firm's product innovation stratege and the performance results with special emphasis on firm size in a developing country. First, a total of 8 strategy dimensions were identified, which constitute the specific elements of firm's innovation strategies. Two independent dimensions of performance were also identified and were found to be closely linked to the strategy adopted. Then, a categorization scheme is developed to distinguish firms according to their size, and proves useful in performance results might be altered for different company size. The findings generally suggest that a well-balanced new product program emphasizing both marketing and technological effort appropriately is needed to make the program successful. The different size of the company is found to call for somewhat different strategy dimensions to enhance the performance results.

The purpose of this paper is to introduce the new products for replacing on the old technical cooperation products which have 24 kinds of industrial inverter model. The core algorithm for vector control and sensorless control and the operation program for LCD operator have been developed. Through the continuous test, the improvement of speed/torque control performance and the control program for special target loads will be performed.

The function and role of museum has changed focused on the experience program and visiter's participation in this time. In Comparison with Korean museums, like this visiter's personal experience has special effects through experience programs of museum in Japan. So, I researched cases of Japan and the survey on experience museum programs should summarized three characteristics as followings implied cultural desire about museum directly or indirectly. 1. Experience programs base on the rural community, identity, and tradition. 2. Boso village museum and Tokusima experience museum harmonized with out-space and institutions, prepare various programs, exhibition, and selling of collections. 3. Through experience programs classifying into visiter's experience at first hand and expert's rehearsal according to difficulty of the job, it is sufficient about visiter's demands.

A computer controlled 5 axis ultrasonic testing system is developed in order to detect flaws in special parts with complex shape. The various kinds of ultrasonic test can be performed automatically using computer program which was developed by DHI(Daewoo Heavy Industries Ltd.). By use of this computer program, the detector location can be programed and the amplitude signal of echo can be processed digitally. The test results can be plotted graphically on a high resolution display monitor in real time base. The test data can be also saved in magnetic memory devices(HDD or FDD) as well as in the form of hard copy through color printer. The computer software contains c- scan, c+a scan processing programs as well as statistical analysis for test data.

Recently avionics equipment and its integration are most important part for implementing high performance aircraft system. This trends are emphasized in the military or special purpose aircraft development program. Flight Test Bed Aircraft (hereafter FTB A/C) - by modified commercial aircraft - was key solution to verify function and performance of avionics system for complex aircraft development program for a while, but there are no experience to use it in domestic airspace of ROK. This paper would like to address what act and regulation is necessary to perform flight operation of FTB A/C with keeping a airworthiness and airspace control policy. and then willing to propose what do we do for improving aviation industry.
