BOM(Bill of Materials) is a listing or description of raw materials, parts, and assemblies that define a product. In manufacturing companies that produce various products with short life cycles, it is very important to manage the BOM of products with various options and versions efficiently. BOM information should be required to share among the departments of engineering, production control, material purchasing, cost management, and shop floor within a manufacturing company. In order to share BOM information efficiently, information system based on WWW(World Wide Web) should be developed. Thus, this paper models and implements Web-based Generic BOM Management System (WGBMS) for management of a number of variant products which are consisted of standard parts under ATO(Assemble To Order) production environment. Also, object-oriented methodology was used to model a generic BOM and phases of navigational design and interface design were introduced to implement the prototype of WGBMS. And Object-Relational Database Management System (ORDBMS) was used to construct the WGBMS database.

This paper reports generating creative ideas based on customer needs using Kano Model and Importance-Differentiation Matrix (I-D Matrix). Nowadays, every customer demands creative ideas on product innovations in order to be satisfied her needs. However, most existing methods are limited to get creative ideas that reflect customer needs. Any creative ideas that do not fully reflect customer needs are obviously more difficult to succeed in the market than those that reflect customer needs. This paper distinguishes each quality elements the customer needs in terms of Kano Model. And it presents the effective ways of generating creative ideas by I-D Matrix in order to overcome current uppermost limits.

The work in this paper presents development of fuzzy logic-based energy management strategy for a fuel cell hybrid electric vehicle. In order for the fuel cell system to overcome the inherent limitation such as slow response time and low fuel economy especially at the low power region, the battery system has come to compensate for the fuel cell system. This type of hybrid configuration has many advantages, however, the energy management strategy between power sources is essentially required. For the optimal power distribution between the fuel cell system and the battery system, a fuzzy logic-based energy management strategy is proposed. In order to show the validity and the robustness of suggested strategy, some simulations are performed for the standard drive cycles.

This paper presents experimental results for peformance management of a Profibus-FMS network. The performance management alms to maintain a uniform level of network performance at all stations under changing network traffic. The performance management algorithm monitors the performance of individual network stations and commands the stations to change their timer values in order to have comparable performance at all stations. In order to determine the amount of timer change, the algorithm employs a set of fuzzy rules. This algorithm has been evaluated on a Profibus network

In this paper, a case study is introduced on the development of an inventory management system for the textile industry. For the low-cost and high-efficient production, a systematic management is needed from make-to-order to delivery. In this paper, an integrated inventory management system for the D company is developed to manage the whole information related with make-to-order, production, delivery, and inventory, and so forth.

In order for the analysis of effect in the respective preventive measures which is being carried out by a small & medium sized company against any potential accident, this research relates to the followings: We investigated the situation of an accident occurred in the company in which his obligation of selecting a safety manager is exempted, in accordance with the industrial safety & healthcare & enforcement ordinance, enforcement rule. We investigated the situation of an accident occurred in the company which entrusted the specialized organization with his own safety control notwithstanding it is free from an obligation to have any safety manager for aiming at the comparison and analysis of the outcome. The economic and preventive effect of industrial accident has been compared and analyzed in order to strengthen the obligation of selecting a safety manager.

Everyone knows how much the company business goal is achieved is the most important to all companies. In order to maximize the business performance, many companies have introduced a diversity of management innovation activities. The effect of business performance is important in the business activity, but an efficiency of output-to-input concept is significantly important. Each year, companies have managed the business through a sum of performance. In terms of the efficiency of business performance, the management is importantly managed. In the efficiency of business performance, there are the main items including the total assets, employees, and operating expenses as the input. As the output, there are the main items of sales, current term's net income. This study is intended to calculate the business efficiency through DEA analysis for companies' business performance, and to study in order for the efficiency of business performance to be considered when the companies establish the mid and long term business plan.

This study closely examines quality management's realities which manufacturing firms have and effective result controls access formula by comparison and analysis on the product of introduction quality control realities and quality management of manufacturing firms in Chollabukdo. In order to accomplish the purpose of this study, this research was progressed as order of literature review and survey. After literature review this study drew up questionnaire on the basis of foregoing literature and executed survey on manufacturing business taking TQM(Total Quality Management) in Chollado's area. The result of analysis are as follows. First, according to the analysis manufacturing of industry's realities, investment in TQM techniques seems to contribute to the performance of manufacturing firms, but most of manufacturing firms quality control do not have strategic orientations. Conseqently, general and strategic quality management system suitable for the realities of manufacturing industry are required. Second, It seems that manufacturing industry didn't recognize strategic importance for competitive advantage. Namely, It was found that firms with less TQM executed non-strategic quality management, compared with firms more TQM.

This study demonstrates a basic concept and designing direction for the realisation of disaster prevention planning in u-City(u-BangjaeCity) that is from establishing a planning system in terms of the areas of professional disaster and safety management for the national disaster management. and designing disaster or safety management system via using ubiquitous technology for the scientific disaster management. In order to realise u-City it is necessary to maps out interrelation amongst various services such as traffic, environment and disaster prevention. Domestic and international case studies regarding the tendency of disaster prevention planing in u-City and its analysis could be the fundamental resource in order to develop the standard model of u-BangjaeCity.

The government should establish internationally harmonious regulations for effective import and export of necessary resources to other countries. However, the use and the number of pesticides used for the same purpose on same crops are depending on the soil and the climate where the crops are grown. Therefore, if internationally harmonized standards are difficult to establish, it is mandatory to conduct a risk assessment based on scientific data to reflect the domestic situation in order to avoid trade friction or conflict between countries. The government is preparing the implementation of a more regulated PLS (positive list systme) than the existing pesticide management system for safer pesticide management reflecting the recent increasing imported food, changing dietary habits, and changing climate. In order for effectively safe and scientific management of pesticides, the government should strive to communicate with consumers properly and the perception of pesticides by consumers should also be changed.
