In this paper, we use and apply statistical tools to planning marketing strategy in advanced markets. New comers with low brand awareness in advanced markets can not attain high profit easily and need more effective strategic approach. In this paper, an effective and practical procedure is proposed to plan marketing strategies to satisfy the customer and increase the market share in advanced markets. The procedure consists of 5 steps : market survey, determining target brand, evaluation of brand attributes, gap analysis to determine the goal, and correlation analysis for effective improvement method. A case study is studied in the European market for electric appliances, between a Korean company and other companies. Various statistical tools are used to analyze the phenomena and some important conclusions are derived for effective marketing.

Six sigma has been evolved into three generations. The first generation focused on eliminating or reducing defects as Motorola originally developed and applied. The second generation focused on reducing costs and improving process efficiency as GE extended the first generation. The next generation of six sigma such as D2MAIC(Discovery, Define, Measure, Analyze, Improve, Control) and ICRA(Innovate, Configure, Realize, Attenuate) has been discussed since the beginning of the 21st century. Although the third generation of six sigma emphasizes value creation, but there are few specific tools for its implementation. In this thesis, some tools for finding opportunities for value creation are suggested. It is explained and discussed with examples how the tools can be applied.

Recently, demand on machine tools has been increased because the machine and automobile industry is booming. Therefore, the machine tools need to have a high accuracy and productivity. To build a high precision machine tool and increase its productivity, structural analysis needs to be carried out for vibration and stiffness of the machine tool before its detail design. However, it is the fact that many manufacturers of machine tools depend on their know-how about design experience. Therefore, in this paper, the static and dynamic analysis is carried out for evaluating a horizontal CNC lathe and then, applied to its detail design. It is positive that the analysis can lead to reduction of design time and improvement of the quality of the lathe as its design proceeds.

Purpose: It can be said that the 21st century is the age of creativity. However creativity has been relatively less considered in comparison with control and continuous improvement in quality management. How to incorporate creativity into quality management is treated in this paper. Methods: The opposing characteristics of quality and creativity are examined, and the possible outcomes resulted from the conflict are reviewed. Previous researches on managing evolutionary and revolutionary changes are also examined. Results: Quality and creativity require each other although they have incompatible characteristics, and can be incorporated into the innovation cycle. Conclusion: Creative thinking tools such as SIT should be included in the quality training and education for the effective operation of the innovation cycle.

Objectives: To review trends of clinical trials on Korean medicine treatments for postoperative sleep improvement. Methods: We searched randomized controlled trials (RCTs) on Korean medicine treatments for postoperative sleep improvement from ten domestic and foreign databases. Sample sizes, diseases, types of operation, diagnosis tools, pattern identification, interventions, outcome measurements, and main results of included studies were extracted and analyzed. Results: A total of 20 RCTs were selected. Most studies were published in China. The most common target disease was cancer, followed by cardiovascular disease. Most studies lacked detailed description regarding participants such as onset, duration of sleep disturbance, and preoperative sleep issues. Herbal medicine was the most frequently used in 12 studies. The most commonly used prescription was Suanzaoren decoction. The effectiveness of Korean medicine treatment on improving postoperative sleep was found to be significant in most studies. Conclusions: Korean medicine treatments might be effective in postoperative sleep improvement. However, the quality of included studies was low. Therefore, further well-designed research studies are needed to provide high quality clinical evidence on Korean medicine treatments for postoperative sleep improvement.

Cohorts are established and operated at medical schools as part of efforts to improve the quality of education. Chosun University College of Medicine clarified the purpose of establishing three cohorts in light of its core values and developed criteria and indicators for each purpose. An organization focusing on cohort construction and operation was established as the Cohort Committee under the Quality Improvement Committee, and guidelines were proposed. In addition, a database and system were developed to handle primary data efficiently, and tools for measuring psychological variables were created. The data collected by establishing a cohort, regions, and admission types of graduates were first analyzed for the following projects: (1) an analysis of the educational process and quality improvement to educate medical professionals who contribute to the community after graduation, and (2) an analysis of the educational process and quality improvement to secure excellence in the medical field (e.g., knowledge and clinical reasoning), using information on the academic achievements of students and graduates as primary data. Chosun University College of Medicine is conducting cohorts and longitudinal studies gradually, starting with a simple, practically feasible system to solve the difficulties faced in cohort establishment and operation. Medical educators hope that future data collection and analysis will improve the quality of medical school education and have practical implications.
