오늘날 현대사회는 인터넷의 보급으로 지식정보화사회로 급속도로 변화하고 있다. 이전 대량생산시대와는 달리 소비자들의 욕구와 기호는 매우 다양하게 형성되고 있다. 여러 기업들이 생산하는 제품들도 대부분 시기와 계절에 따라 생산율과 판매율이 달라지고 있는 실정이다. 제품들의 생산 및 원가산출, 적정재고량 파악을 위해 기업들은 BOM(Bill of Material)을 작성하여 관리하고 있다. 하지만, 다양하게 변화하는 현대사회에 요구사항을 반영하지 못하고 여러 문제점들을 야기하고 있다. 본 논문에서는 원자재 공급업체에서부터 판매회사까지의 자동발주시스템을 완성하여 보고자 한다.

Systematic research of metal alkoxide electrophoretic deposition has been developed. The formation mechanism of electrophoretic deposits has been offered. The structure study of dry and heat-treated electrophoretic deposits has been established. The concrete examples of one and bi-component oxide thin film formation were considered. The new approaches for thin film technology have developed on various substrates of different shapes and sizes. The correlation between thin film structure, mechanism of their formation, and physico-chemical properties has been determined.

The LED backlight can be designed to have the desired uniformity by using many combination of reflector patterns. The uniformity of the LED backlight can improve by applying the specially designed reflector patterns. In this paper, it was shown that the 72.7% of luminance uniformity of the LED backlight with reflector patterns was obtained by computer simulation.

The dendritic molecule has focused on the target material for photodynamic therapy, and used as the energy harvesting molecule for the application of medicinal field. Those molecules have also researched on the molecule design for the preparation of new dendritic material on PDD and PDT. In this presentation, new dendritic molecules are introduced on the development of DPPZ dendritic molecule for PDT and the efficient synthetic process.

To shorten product development time and cost, integrated information managements of product, manufacturing process and resource are essential. In the area of material addressing, process engineers should make their decisions in the manner of collaborative engineering in order to reduce the manufacturing preparation time and cost in the product development and production. A digital virtual factory which is an united digital model of entire factory could be very useful for these areas. In this paper, the digital virtual factory is constructed and used for material addressing and analysis of an automotive general assembly shop. We developed the material addressing system for automotive general assembly shops using digital virtual factory models and nesting algorithms, and applied it to realistic problems of a Korean automotive company as an convenient and effective way of material addressing.

The need of the life be healthy is increasing to the human life prolongation. There are lots of companies using the use of environment-friendly material as the sales strategy today. But a consumer is insufficient of the information about the environment-friendly ingredient. The level of Consciousness for the consumer standard of living and health got higher recently. And the interest about the furniture material comprising the residential space rose. I consider the consumer changing mind the safety of the conservation of the environment and mankind. Also, future of the environment-friendly material can say that is light if develop various the environment-friendly material description and accomplish the Higher Value-added of resource.

Material selection is a complex problem in the design and development of products for diverse engineering applications. This paper is aimed to present a fuzzy decision making approach to deal with the material selection in engineering design problems. A fuzzy multi criteria decision-making model is proposed for solving the material selection problem. The proposed model makes use of fuzzy TOPSIS (Technique for Order reference by Similarity to Ideal Solution) with trapezoidal numbers for evaluating the criteria and ranking the alternatives. And result is compared with fuzzy VIKOR (VlseKriterijumska Optimizacija I Kompromisno Resenje in Serbian, means Multi criteria Optimisation and Compromise Solution) which is proposed by Jeya Girubha and Vinodh [2012]. The present paper is aimed to also improve literature of fuzzy decision making for material selection problem.

The primary role of MRP(Material Requirement Planning) is to make a production plan so that we have an exact quantity of right materials on needed time at right place. But the ignorance on capacity constraints makes some problems whenever production schedule is established. To increase the performance of MRP system, a novel approach which is based on new input data structure is suggested. The new input data structure includes all the information about Material BOM, Routing and resource data so that we can easily examine the usage of resources and generate higher performance production plans.

This research is aimed to study the finishing material applied in interior space for improving residential environment. First of all, it finds out what is 'Sick Building Syndrome' and 'Sick House Syndrome', how harmful to human body about indoor air pollution substance (such as volatility organic compound, formaldehyde) and investigate the effect when the environment-friendly finishing material is used. Secondly, classify and examine all kind of finishing material applied in interior space. Finally, after emphasize the importance of environment-friendly finishing material from domestic or overseas, this research suggest the basic information of environment-friendly finishing material in order to use in the future buildings.

There is a need for effective tracking and control of material loading and delivery time especially during the finishing-work phases to eliminate the need for lay-down space on the site. Hence, it is essential to monitor the relevant information regarding material procurement in construction sites, and it is also the key factor for successful site control and the adoption of the Just-in-Time concept for high-rise building construction. The purpose of this study is to test RFID's readability in order to develop a finishing material monitoring system through the application of RFID technology.
