The research in the field of quality engineering has mainly focused on the manufactured products. The philosophy and concept of the existing quality engineering should be equally applicable in the coming e-Business era. However, there would be numerous new quality-related issues in the e-Business environment, due to the fundamental change in the business processes, which did not exist in the past. This paper first proposes a framework for quality engineering research suited for the e-Business environment, and then identifies major quality-related issues that should be resolved in the near future. It also evaluates the potential usefulness and limitations of the existing quality engineering tools in resolving such issues.

This paper discusses some variables of innovation arised in the Mathematical Curriculum reform, This means that we should consider the curriculum change based on those variables so that the Mathematical Curriculum could be created on our culture, need of industrial society and nation's system. Those variables could be described as follows. (1) Extension of Compulsory Education (2) Needs of industrial society (3) Change of School environment (4) Integration of School subjects The research method used in the study was the interview-analysis method which the researcher firstly send the questionnaire and then have interviews with the target people. This study also suggests informally a possible solutions of problem that current mathematical curriculum is faced. Those solutions include the change of mathematics syllabus based on the adaption toward the real problems arised in real world.

Changes in manufacturing system are those that occur during production and cause the systems to behave unpredictably. So scheduling problem in this dynamic Industrial environments is very complex. The main concept of this dissertation is to continuously monitor a manufacturing system status(Rate of Prior Job, Rate of Large Job, Rate of Shortest due date Job, Job Interval Time) and detect or predict a change so that scheduling system will react by modifying production schedule(dispaching rule) to lessen the effects of this change.

Global financial crisis at 2008 bring about the great change to the company itself and its environment. In these days, the company needs change to the ambidextrous organization, which have more efficiency processes also have more attractive products and services. Ambidextrous organization purse exploiting and exploration innovation program. For the existing process's incremental and rapid improvement, the exploiting innovation programs are used such as 6 Sigma program and so on. For the new business model's searching and developments, the exploration innovation programs are used such as blue ocean program and brainstorming and so on. In this paper is presented the new procedures, for the new business model development, combining exploration and exploiting innovation programs. To obtain the creative business ideas, various exploration methodologies are adopted based on 6 Sigma's methodology, The new procedures are applied to the venture company and examined its validity.

The 4th Industrial Revolution has been rapidly changing the environment of all industries and the new technologies as included in the 4th Industrial Revolution has taken the lead in this change. Domestic SME need to change according to the 4th Industrial Revolution. Specially, it is necessary to introduce smart factories to the SME. Thus, this study suggests strategies for successful introduction of smart factories to SME through SWOT analysis about the situation of the SME. As strategies for utilizing its strengths, first, it is an activation through superior competitiveness. Second, the utilization of excellent technology and information is considered. Third, it is suggested to utilize global network-based environment. The strategies for making up for weakness are provided as follows. First, it is suggested to raise awareness of information security. Second, it is considered to establish technical standardization for the construction of evaluation system. Third, the promotion of manpower to secure professional manpower is suggested. The implication of this study is that it suggests the necessity of smart factory to understand and prepare for effective strategies for SME and various external strategies for the fourth industrial revolution.

In this study, two kinds of industrial filter bags were tested for their filtration performance to apply the existing bag filter systems. Experimental variables were examined for pressure drop, cleaning interval, residual pressure drop, cleaning efficiency, fractional grade efficiency, total collection efficiency according to the filter bag structure. According to these results, the filter bags tested in this study demonstrated good performance in dust collection. This was also true for the double surface filter bag. The lifetime was longer than the round type filter bag because the filtration area was more than 1.6 times wider and the filter quality factor was much higher. Therefore, double surface filter bags are suggested to be used in order to increase filtration performance of the bag filter systems.

Montmorillonite is one of representative inorganic clay particles. As the characteristics of clay particulate matter in aqueous environment determine the efficiencies of wastewater treatment and some industrial operations, it is essential to understand its aquatic behavior in relation with turbidity. The change of electrokinetic potential of montmorillonite suspension shows that it tends to negatively increase as the pH of suspension increases. In addition, it is observed that its potential is around 0mV when the solution pH is ca. 5. The turbidity of suspension is shown to be very low when pH is lower than its isoelectric point. However, the turbidity gradually enhances according to beyond isoelectric point. These results reveal that the correlation between electrokinetic potential and turbidity for clay mineral suspension is peculiar which should be fundamentally considered for systematic treatment of wastewater.

No matter what Corporate Social Responsibility has been discussed, that has been indifferent. But, new concept of Corporate Social Responsibility, Socially Responsible Investment is attracted recently and these come to the front with management strategy or policy in 2004. Corporate Social Responsibility is progressing toward direction of standardization over dimension of simple discussion. Continuance possibility Management is gathering strength by supplement method that limitation of Environment Management and Ethics Management are emphasized. How does corporation cope with change of business environment?

As Gyoto Agreement, the Climate Change Agreement, has become effective, total weight restriction on waste has started in each country and environment issue becomes one of the most important global issues. Therefore, environmental logistics became important matter, and industries need to establish production system for environmental conscious products and services. In this paper, we compare and analyze environmental conscious logistics activity(ECLA) that affect Carbon Dioxide Discharge(CDD) and packaging waste caused by logistics activity in Korea and Japan. We also propose the optimal alternative to the problem by this comparison and analysis.

The purpose of industry-education cooperation field training is improving students' abilities & skills by working at industrial companies and experiencing how to apply their school knowledge to a real work for some period of time. The followings are recommendable ways of industry-education cooperation field training management to improve the students' adaptability of industrial companies with the most effectiveness (1) Prior to everything, setting the industry-education cooperation field training program to have extreme efficient and managing it with exhaustiveness & intensiveness is necessary. (2) Before sending students to industrial companies for education, the committee must make an inspection of industrial companies to decide whether they have the fine educational value. (3) To assign eve student to proper industrial companies, school authorities must survey the aptitude, desire and ability of each students and peculiarities of each industrial companies. (4) Figure out a way to increase the students' adaptability with a highest degree. (5) To help the employment of students who finished the industry-education cooperation field training with on admirable record, the committee must discuss that matter with industrial companies & students.
