Bill of material (BOM), which structurally represents the relation among parts constructing a product, is usually created when enterprises start to develop a new product. And it is shown as various types of BOM according to business needs and usage such as eBOM (engineering BOM), gBOM (green BOM), mBOM (manufacturing BOM), pBOM (process BOM), etc. eBOM, generally called BOM and created in the design stage of the new product, includes the drawing information of parts in the view of product function. eBOM is extended to gBOM adding the material information of parts to cope with international regulations for environment. eBOM is transformed to mBOM, which includes manufacturing sequence of parts and adds some parts required to fabricate parts and to assemble the product. mBOM is also extended to pBOM adding the process information of each part and additional assembly processes. This study introduces the concept of multi-BOM covering eBOM, gBOM, mBOM and pBOM, and proposes an advanced way to manage product data using multi-BOM system. The multi-BOM system proposed is to manage their relations using transformation function of BOM and master information of all BOMs.

Purpose: For effective quality assurance activities, BOM-based quality assurance method is presented. This study introduces various BOM conversions such as Q-BOM, T-BOM, and S-BOM based on M-BOM structure. Methods: Product quality control via Q-BOM manages inspection/audit information, overall supply-chain of product, part requirements, and inventory status. T-BOM manages part traceability, and S-BOM enables statistical control over key process and parts at various hierarchy levels. Results: Quality plan template was developed based on the study results of BOM system including Q-BOM, T-BOM, and S-BOM. Conclusion: Through BOM(Q-BOM, T-BOM, and S-BOM) study and development of quality plan template, more systematic and comprehensive quality management plan is achieved.

In accordance with the trend for cooperation of related company, BOM (Bill of Materials) has become an important factor in the manufacturing of production. BOM manages a various basic information of design, production, and process and so on. Especially, automobile industries are related to many company, they build a cooperative system from the communication of information. In this study, we have analyzed a BOM structure of a well-used automobile part industry and proposed a structure of engineering BOM, manufacturing BOM, process BOM for cooperative environment. A proposed various BOM structure are flexible in responding to the situation of structure alternations for automobile part. And also they include in environment factors. It is expected that these BOM structure will be used to basic template in automobile part industry which could be loaded with cooperative hub-system.

This study was undertaken to determine whether Bombycis Corpus extract (Bom) has antioxidant action. Kidney tissues were exposed to t-butylhydroperoxide (t-BHP) to induce oxidative stress. Lipid peroxidation was estimated by measuring malondialdehyde, a product of lipid peroxidation, and cell injury was estimated by measuring lactate dehydrogenase (LDH) release in rabbit renal cortical slices. t-BHP increased lipid peroxidation and LDH release in a dose-dependent manner over the concentration range of 0.1-1 mM. Such effects of t-BHP on lipid peroxidase and LDH release were prevented by 0.5% Bom. When tissues were treated with t-BHP in the presence of various concentrations of Bom, lipid peroxidation and LDH release were dose-dependently inhibited by Bom. Bom at 1 and 2% concentrations inhibited lipid peroxidation and LDH release in normal tissues. Bom at 2% concentration increased glutathione peroxidase activity in tissues treated or untreated with 1.0 mM t-BHP. However, catalase activity was not altered by addition of Bom. Bom inhibited generation of reactive oxygen species. These results indicate that Bom inhibits lipid peroxidation and cell injury in tissues treated with or without oxidant and this effect is, at least in part, attributed to increased activity of glutathione peroxidase and a direct sacvenging action.

상품의 개발을 위해서는 개발과 양산이라 하는 크게 2가지의 단계가 필요하다. 따라서 이에 필요한 부품을 관리하는 것에도 개발과 양산에 따라서 관리되어야 한다. 본 논문은 전자소자 품번 체계를 개발 및 양산 단계에 따라 표준화하고, 이를 기반으로 BOM 시스템을 구축한다. 이후 HL만도 내의 System에 이관하여 표준화된 품번을 활용한 System BOM 및 이력 등을 관리할 수 있을 것이다. 이는 각 연구소에서 공용화 환경을 구축할 수 있고, 구매, 품질 등 부서에서의 체계적인 환경 구축 수립을 통해 업무 수행에 많은 개선이 있을 것으로 예상된다.

DSME has successfully developed the unified CAD system (DACOS) for the commercial ship based on its design know-how accumulated for several years. Currently, DSME is expanding the unified CAD system to plant and special ship design. In this paper, the development of pipe design, especially, isometric drawing and BOM(Bill of Material) generation will be introduced isometric drawing and BOM generation are major activities of pipe design in shipbuilding. The drawing is used for pipe construction and installation while the BOM is used for purchasing and manufacturing pipe line. These activities are time-consuming and tedious jobs done by designers because the drawing should be generated as a non-scaled symbolized drawing that can be easily understood and the BOM information should be extracted without mistake. Therefore, we implemented automatic isometric drawing and 80M generation system for pipe design. In this paper, the developed system and the used technology will as well be introduced and a design output in a plant project as an applied example will be illustrated.

An M-ary bi-orthogonal modulation scheme for ultra-wideband (UWB) systems capable of narrowband interference (NBI) suppression is proposed in this letter. We utilize a set of bi-orthogonal pulse series to achieve NBI suppression. Through analysis and simulation, we verify that the proposed scheme can suppress NBIs effectively.
