In this study, which is the basis for industrial presses to target small and medium enterprises with production information system is designed. Production information in real time on-site digitizing and transmitting data to a standard PC is to base operations. Personnel management, safety management, production management is to increase the efficiency. Therefore, at low cost is to encourage computerization within the company. These embedded systems and wireless communication module has a database management program installed in order to raise productivity and competitiveness will improve.

Nowadays, our industries and occupation are increased under the economy development of government. So, this paper introduce to compare with coefficient's of correlation on the time series of the education and the qualification in our country. For this reason, the decision making to qualifications' foresight which will be change to the education category-prospective on the time series. The qualification has claasified 5 degrees-master craftsman, professional engineer, engineer, technician(or industrial engineer), craftsman - and 516 qualification items. Education has classified to 4 degrees(7 degrees) - elementary, middle, high, high scholastic level school(college, university, graduation). This paper has matched to educational classification and qualification classification through the following method. We defined the same level between education and qualification after analysed correlation under the time series, so the craftsman equals high school graduation people, technician equals college graduation people, engineer quals university graduation people, now we could not analyse master and professional levels. This paper will suggest to the qualification's future policy direction and improve the education policy direction.

We need a study of the ratio of successful applicants control methodology about the national technical qualification under the global-green industrial society and rapid change of international circumstances, infinite competition rider society under FTA aspects. It is necessary to develop of HRD Korea selfishness and increase brand value of national technical qualification. So, this study is analysed to the ratio of successful applicants of national technical qualification toward change of the 'bank of problems' control rule, various characters of candidates and the trend of demand and supply of labours instead of the absolute evaluation method. Accordingly, this study suggests to a methodology for the forecasting model of the ratio of successful applicants using the level of problems difficulty and pattern and the candidates academical carriers.

오늘날 중소기업의 자동화 및 정보화 설비구축을 보면 과거보다는 높은 발전을 이루고 있다. 그러나 이러한 독립된 설비, 장비, 시스템의 기능을 살려 관리와 경영의 효율을 높이기 위해서는 인력과 비용이 많이 소요되어 운영계획을 포기하거나, 규모를 축소하여 생산성향상에 저해되는 상황이 발생하기도 한다. 따라서 본 연구에서는 최근에 반도체 기술의 발전으로 임베디드 마이크로프로세서의 개발로 보다 용이하고, 빠르게 시스템을 설계하거나 변경을 할 수 있도록 하드웨어와 소프트웨어의 인터페이스를 구현하였다. 특히, 중소형 제조기업에서 실시간으로 생산정보를 통해 경영에서 필요로 하는 정보를 생성하는 프로세스를 제시하였다.

오수처리시설물 제어하는 기존 제어장치는 PLC에 의한 것으로 조건제어, 유지관리, 기능확장에 따른 운영에 많은 어려움을 가지고 있다. 본 연구에서는 임베디드 시스템에 의한 제어장치를 개발하여 다양한 환경에 대한 유입수량, 농도상태에 따른 반응시간 및 전체 진행시간을 프로그램 하기 쉬운 구조로 하였다. 또한 효율적인 장비가동으로 설비보전을 할 수 있어 유지비용을 줄일 수 있다. 가장 큰 목적은 사용자와 관리자가 쉬운 유지관리를 위해 보다 더 신뢰할 수 있는 배출수 운영으로 하천 수질개선을 위함이다.

In the study, Methods for operating measures in equipment security to find out dangerousness timely in the system and to need for the prevention and measures. The method for analyzing and reconstructing the causes of accident of equipment in site, and try

This study intend to make easy modification, even if there is a new job or structure change, by modularizing program and computerize and automation of production control management used in CIM. under the condition where manager control production on the j

The purpose of this paper is to solve the problem that is occuring in assembly process and to progress the productivity by process analysis methods for manu-open and closed model(DWV-20/25DRG), and auto-open and cloesd model(DWV-20/25/DRA)-ventilation fan. Also, this paper is studied by data of ＇D＇ company's product.

Today, facilities are composed of many complex components or parts. Because of this characteristics, the frequency of failures is decreasing, but the strength of failures is increasing; therefore, the failure analysis about many complex components or parts was needed. In the former research about Fault Tree Analysis, failure data of similar facilities have been used for forecasting about target system or components, but in case that the system or components for forecasting failure is new or qualitative and quantitative data are given simultaneously, there are many difficulty in using Fault Tree Analysis with this incorrect failure data. Therefore, this paper deal with the Fault Tree Analysis method which be applied with Fuzzy theory in above case. In case that , therefore, if there is no the correct failure data, it is represented a system or components as qualitative variable. subsequently, it converted to the quantitative value using fuzzy theory, and the values used as the value for failure forecast.

본 연구에서는 생산성이 저하되고 있는 DWV-2O/ 25 DRG(수동개폐식) 모델과 DWV-20/25 DRA 모델을 대상으로 조립생산시스템에서 발생되고 있는 애로공정의 문제점과 불량품 발생 상태를 관리 기술적인 견지에서 분석하여 생산성 향상을 증대하고자 하는데 목적이 있다.

Production schedule and realization quantity of Large type bus [929(HD), 928, 928-A(SD), 937E/L, 937/L,] were analyzed in order to intruoduce FMS(Flexible Manufacturing System) appropriate for varities of customer desire and multi-item, small lot production. And this paper is aimed to propose introduction method of FMS, analyzing zig tools change times and idle times with production line and workers as an object. According to analysis results, only simple spec., depending on bus type, changed with decrease in production. For 929(HD), 928,928-A(SD), 937Eh, 937/L bus type, there was no harmony between schdule and realization. Therefore, it caused many difficulties in part supply. And there was loss of manpower and reduction of productibility due to idle time of process with bus type change. Production processes were operated inefficiently because tact time exceeded or shortaged of allow time.
