Workflow Management System(WfMS) enables corporations to manage business processes efficiently The purpose of this research is to develop a management system that is capable of managing complicated business processes efficiently under distributed environment where many companies or divisions are participating. Run-time encapsulation proposed in this paper is a system design methodology that enables appropriate response to the dynamically changing processes by using nested processes. We have implemented WfMS under Web environment using run-time encapsulation. Run-time encapsulation using nested process is an efficient development methodology for implementing heterogeneous and distributed WfMS under web environment.

When accidents that relate to a large numbers of people occur, such as disasters involving group tours by ship or aircraft, or large-scale chemical leakages, it is very important to know the personal identification of victims and to determine their locations and status. It is true that there will be serious damage or injury to people who engaged especially when information does not transfer properly or people get inaccurate one. In this study, therefore, we analysed the disaster response management system for rescued people of the Sewo ferry sinking accident. Based on the analysis we proposed to improve the real-time disaster management system with ICT(Information & Communication Technology).

With the increasing interest of a demand side management using a Smart Grid infrastructure, the demand resources and energy usage data management becomes an important factor in energy industry. In addition, with the help of Advanced Measuring Infrastructure(AMI), energy usage data becomes a Big Data System. Therefore, it becomes difficult to store and manage the demand resources big data using a traditional relational database management system. Furthermore, not many researches have been done to analyze the big energy data collected using AMI. In this paper, we are proposing a Hadoop based Big Data system to manage the demand resources energy data and we will also show how the demand side management systems can be used to improve energy efficiency.

This paper investigate and compare the appraisement methods and programs are related in Ergonomic, which in foreign country are approved to appraise worker's posture and environment. First, Search the appraisement program to need and develop the program. Second, Design and develop the standard model that easy and accurate, and apply to our country workstation. To response above mention, we made the EWAP(Ergonomic Workplace Analysis program) and purpose of EWAP is assisting the activity of safety management to assess more detail and delicate through quantitative methodology in which operated the Ergonomic Workplace safety management. EWAP can provide the more convenience where need to analyze their Ergonomic Workplace problem and developed by the algorithm of Ergonomic Workplace Analysis management.

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.

The fuel cell system has inherent limitation such as slow response time and low fuel economy especially at the low power region, and thus, the battery system has come to be used to compensate for the fuel cell system. This type of hybrid configuration has many advantages, however, the energy management strategy is essentially required. The work in this paper presents survey on recent power management strategies for fuel cell hybrid electric vehicles. For three power management strategies: basic control method. object function-based control method, and fuzzy logic-based control method. each strategy is reviewed and discussed with other strategy.

The purpose of business strategy is to achieve competitive advantages which includes higher efficiency, better quality, more innovation and faster customer response. In other words, The business strategy is to build unique capability of lower cost and/or differentiation. In production aspect, unique capability means better production power with better performance at 3M(Man, Machine, Material) of input and PQCDSM (Product, Quality, Cost, Delivery, Safety, Moral) from output. The Total Productive management (TPM), a series of improvement activities focused on reduction of equipment loss, is a tool to establish business competitive advantages. In this paper, several domestic companies who won the Japan TPM Award have been studied. It is found that there is a strong cause-effect relationship between TPM and competitive advantages because. 1. TPM can change employees mindset effectively. 2. TPM can upgrade employees capabilities. 3. TPM can lead to excellent productivity.

Many countries are enforcing the Product Liability Act to ask the responsibility for the supply of the safe products. Thus, the safety of the product becomes one of the most important elements in modern corporate management. Diamond tool industries producing risk-high products cannot make an except to this situation. This research presents how Diamond tool manufactures in korea to respond effectively to Product Liability through construction of Product Safety Management System.

A fundamental concepts of business environment changes and the importance of stakeholder's value creation is changing in the business. This study ISO9004: 2009 quality management system of Category 5: Strategy and Policy, Category 10: improvement, innovation and learning (Note) SBK target was to develop a model that is the company's sustained success. Three concepts of the new revision of ISO9004" in response to environmental changes," "learning", "innovation" (Note) SBK applied to the project settings and talent establish long-term vision was to establish the process as the organization's learning content was TDR for the creation of exceptional and innovative programs were introduced. As a result, (Note) SBK three years of continuous business performance indicator has grown dramatically to more than 50% continued success is going to create business models. But 100 years to accomplish the vision, ISO9004 model needs to extends the entire category as a management system to achieve the optimization needed.
