최근 인터넷을 이용한 의류 관련 쇼핑몰이 증가되고 있다. 그에 따라 이용자들도 오프라인 매장뿐만 아니라 온라인 쇼핑몰 매장을 즐겨 찾고 있으며, 이에 따라 온라인 쇼핑몰의 차별성이 중요시 되고 있다. 본 논문에서는 이러한 온라인 쇼핑몰의 차별성을 극대화하기 위해서 오프라인 매장의 장점을 살리고자 하였다. 오프라인 매장에서는 매장 직원에 의한 상의 하의 추천이 가능하고 이에 따라 매출향상 및 이용자의 만족도를 이끌어내고 있다. 이러한 오프라인 매장의 장점을 온라인에서도 그대로 실현하기 위해서 의류의 색상을 계산하여 나오는 색상 값을 색조합표를 기반으로 하여 가장 어울리는 의류에 대해 자동으로 추천해주는 시스템을 설계하였다.

In this paper, we proposed a design method of parameterized viterbi decoder, which automatically synthsizes the diverse viterbi deciders used in the digital mobile communication systems. It is designed to synthesize a viterbi decoder specified by user-provided parameters. Those parameters are constraint length, code rate generator polynomials of teh convolutional encoder, data rate and bits/frame of the data transmission, and soft decision bits of viterbi decoder. For the design of the parameterized viterbi decoder, we designed a user interface module C-language, and a viterbi decoder module in a hierarchical atructure using VHDL language and its generic statement. For the verification of the parameterized viterbi decoder, we compared our synthesized viterbi decoder with the conventional viterbi decoder which is designed for the IS-95 CDMA system. The proposed design method of the viterbi decoder will be a new method to obtain a required viterbi decoder in a very short time only by supplying the design parameters.

In this study, an automated ultrasonic testing system and post signal and image processing techniques are developed in order to construct ultrasonic flaw images in weldments. Image processing algorithms are built into the flaw image processing system for the automated ultrasonic testing system. The developed signal and image analysis algorithms addressed in this study include an A-Scan data compression algorithm, ultrasonic image amplification algorithm and B-scan flaw image correction algorithm(SAFT). This flaw image processing system for the automated ultrasonic testing system can be applied to various inspection fields.

The vibration, which often occurred in a two inertia motor system, makes it difficult to achieve a quick response of speed and disturbance rejection. This paper provides an autonomous pole assignment technique for three kinds of speed controllers (I-P, I-PD, and State feedback) using GAs(Genetic Algorithms) for a two-inertia motor system. Firstly, the optimal parameters are chosen using GAs in view of reducing overshoot and settling time, then those are used in computing the gains of each controller. Some simulation results verify the effectiveness of the proposed design. The proposed controller is expected to be the autonomous design way for controlling a two-inertia motor system with flexible shaft.

In this paper, a new approach to the automation of the cultivation in a green house is suggested and a practical automatic control cultivation system is implemented. To automatically control and optimize the very nonlinear and time-varying growth of farm products, a hybrid strategy(FECA, Fuzzy Expertized Control Algorithm) is proposed which serially combines a fuzzy expert system with the fuzzy logic control. The fuzzy expert system(FMES, Fuzzy Model-based Expert System is intended to overcome the non-linearity of the growth of farm products. The part of fuzzy controller(FLC, Fuzzy Logic Controller) is incorporated to solve the time-variance of the growth of farm products. Finally, the efficiency and the effectiveness of the implemented agricultural automation system is presented through the cultivation results.

Recently, automatic control or application of measuring instrument with computers is rapidly increasing. In this paper we designed automatic incubation system that has functions of control and monitoring of measuring instrument, analysis of measured data, and automatic control by using LabVIEW graphic program that can easily collect, control, analyze, and apply data. Then to inspect the system we produced Incubator. Internal environment is measured by a sensor and each device is setting and controlled to create the optimum environment after finding hatching environment of selected individual from Database file for incubation. Through this functions, problems of hatching rate and quality that were affected by minute change of hatching environment are dealt successfully with, and retrenchment of labor and cost is expected as well.

현대 사회에서 급속한 기술의 발전으로 인해 휴대용 전자제품의 기능이 점차 발달하고 있고, 그에 따른 새로운 제품 출시 주기도 점점 짧아지고 있다. 이로 인하여 소비자의 성향을 빠르게 분석하는 것이 무엇 보다도 중요시 되었고, 이를 위해 빠르고 쉽게 소비자성향을 분석할 수 있는 설문조사시스템이 보편적으로 사용 되고 있다. 하지만 기존 온라인 설문조사시스템은 설문을 쉽게 생성하고 더 정확한 결과를 얻는 것에만 초점을 맞추고 있기 때문에 빠르게 변화하는 휴대용제품에 기존 설문조사시스템을 이용할 경우 많은 노력과 비용이 들게 된다. 따라서 본 논문에서는 한번 설문을 생성하면, 신제품의 추가가 있거나 제품의 정보에 변화가 있을 때 마다 설문이 자동으로 변형되도록 설계하였다. 그리고 모든 소비자에게 개인화된 설문이 자동으로 생성되어 보여 지도록 설계하였다.

This study is related to the development of a design automation system for the construction design phase of steel structures. The system intended for beam splice friction connections using high-strength bolts. The standard design method and standardization principles that are suggested in the design manual for standard connections using high-strength bolts published by the Korean Society of Steel Construction(KSSC) were reviewed. A structural analysis algorithm was formulated from the review. A design automation system that can automatically calculate the structural design of connections and automatically generate the connection model without separate inputs was developed. To verify the validity of the developed system, its results were compared with the date in the table for the connection design in the Design Manual. The development system was also applied to the sample model. Then the structural design results were compared with the properties of the connection models and drawings created from the results.
