We achieved a Quantitative economic growth through rapid developed in 1970' and 1980'. It was confronted after IMF crisis that we needed to improve the past economic policy and the industrial structure. In line of that, the problem of the industrial structure like huge accidents of 1990' converted the recognition of safety. And to improve the conversion, the research of a safety management was needed. In this paper, we thought 4M1E(Man, Machine, Method, Material, Environment) as the cause of accident using the principal of process, assuming that output is accident. Applying 4M1E to the structure of QFD(Quality Function Deployment), we propose the safety function deployment, which has the flow line as followed; demand safety, safety characteristic, direct cause, 4M1E and safety management.

The modem industrial society is developing while growing more diverse and gigantic. Accordingly, occupational injuries or accidents can be caused in various situations, not just in the limited range of workplaces but also in the surroundings, and interest has increased in the prevention of occupational accidents with respect to occupational health and safety, and environment. Thus, this thesis will consider 4MlE (Man, Machine, Method, Material, Environment) as the fundamental causes of accidents and introduce a model of system in which the output of the process control system is replaced by accidents with its input by 4M1E. Furthermore, it will demonstrate how occupational hazardousness can be measured, whereby it can also be rated, by examining the relationship between 4M1E and types of accident in terms of the categories of severity, frequency, and detectability, based on the application of the model to the framework of FMEA.

Integrated Supply Chain Management is a important subject for all enterprise activities as include logistics/sales, transfer and storage, manufacturing, purchasing of materials. A recent customer wants to receive high level service of all parts as Qualify, Delivery, Cost and Product. Therefore, Enterprise effort to supply for customers needs use some techniques like Data Mining, POS, MIS. Inventory and Logistics cost is the highest expense of all cost from first supplier to final customer on supply routine. So, SCM's basic purpose is reduce to that cost. So that this paper explain necessary, background, concept of SCM, analyze several using methodology and function of main SCM solution, after propose to ATP model include arithmetic procedure, functions, input data for determines available due date.

The individual rotten water purification tank recently discharges wastewater and sewage through the outlet without purification ability. The outlet water and affiliated water purification tank with microorganism cultivator tank cultivates microorganism and then drops the value BOD, COD of sewage and discharges the quality of water into the outlet. The blower and water pump operating continuously prompts the waste of energy and deterioration of equipment. Each room of deposition tank, foaming tank, microorganism cultivator tank is equipment with the sludge detection senses so it can detect the density of each room. The power-drive plant of the blower and water pump which ate the system cultivating the microorganism must be made as fuzzy controlization (If the sludge amount of each room become higher, the rate of operation of blower and water pump must heighten, on the contrary, in case of row sludge amount, the total handling amount and microorganism handling amount of each room of control. Tank reducing the rate of operation must be DB. At present, the blower amount in proportion to the sludge and oxygen demanding amount has to control. Each mom must be checked outlet level of the outlet, also each room must flow backward discharge materials, and must operate feed-back control until we want to be come as a below value of BOD/COD(10PPM ; KS).

최근 기업활동의 자재구매, 제조, 보관 및 운송, 유통/판매까지 포함한 공급체인 전체에 대해 통합관리가 중요한 비스를 받고 싶어한다. 이에 따라 오늘날의 대부분의 기업들은 고도의 기술을 요하는 정보시스템의 도입과, POS, Data Mining 등과 같은 기술들을 이용하고 고객의 요구 사항들을 적시, 적소에서 파악하여 고객이 요구하는 상품과 서비스를 공급하기 위하여 최선과을 정리하고 주요 SCM solution에서 제공하는 기능 및 사용된 방법론을 분석하여, 이를 바탕으로 주문 접수 시 주문물량의 가능납기를 산정하기 위한 입력데이터, 고려요소, 연산절차 등을 포함한 ATI(Available to Promise) 모델을 제제로 부각되고 있다. 현대의 고객들은 제품이나 납기, 품질과 같은 부문에서 높은 서의 노력을 다하고 있다. 최초의 공급자로부터 소비자까지 상품이 전달되는 과정 중에서 재고와 물류비용은 모든 비용의 대부분을 차지하고 있다. 이에 대한 비용을 줄이려고 하는 것이 공급체인관리(SCM)의 기본적인 목적이라 하겠다. 이에 본 논문에서는 공급체인관리(SCM)에 대한 개념과 배경, 필요성 등시한다.

In this study, an overall survey of ERP system and methodology are first introduced, then an efficient way of const겨cting ERP system is suggested through a case study on S company S company has not reached the goal of ERP system as it planned and is still working on the project. The main idea for the efficient construction methodology of ERP system is that BPR (Business Process Reengineering) should be accomplished and the company should have enough time to test the ERP package and a proper ERP team organization before the ERP system is introduced. It is suggested that introduction of ERP system bring about benefits to companies in terms of effective management system.

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.

기업에서 발생되는 손실 부분 중 커다란 부분을 차지하고 있는 것이, 산업재해로 인한 인적ㆍ물적인 손실이라고 할 수 있다. 산업재해를 줄이기 위한 방법으로 여러 가지 측면에서 다각적인 노력을 기하고 있으나 현재 기업의 산업안전에 관한 실태를 살펴보면 인간중심의 안전관리보다는 기계중심의 안전관리가 더 우월하게 이루어지고 있는 실정이다. 문명의 발달로 아무리 기계기구로 좋아졌다 하더라고 그것을 사용하는 인간이 제대로 사용할 수 없다는 안전성은 확보 될 수 없을 것이다. 산업재해를 예방하기 위한 방편으로 기업 내에서 실시되는 산업 안전 교육부분에 대한 정확한 실태 조사를 통해 산업안전교육이 기업 내에서 효율적으로 자리잡아 기업의 생산성 향상에 도움이 되고자 한다.

Si 기판을 실온과 600˚C로 유지하면서 동시 증착 방법으로 (Ti+2Si)를 증착한 후 N2 분위기에서 Ti를 증발시켜 TiN(300Å)/(Ti+2Si, 300Å)/Si(100) 구조의 시료를 제작한 다음 초고진공에서 in-situ로 열처리하여 양질의 TiN/TiSi2-bilayer를 형성하였다 열처리 온도가 700˚C 이상에서 (111) texture 구조를 가지면서 화학 양론적으로 Ti0.5N0.5인 박막과 C54-TiSi2박막이 형성되었다. TiN/C54-TiSi2/Si (100)구조의 계면은 응집 현상이 없이 평활하였으며, C54-TiSi2상은 에피택셜 성장되었다. TiN/TiSi2-이중구조막의 면저항은 열처리 온도에 따라 감소하였으며, 700˚C 이상의 열처리 온도에서는 면저항 값이 2.5Ω/cm2 였다.
