Six sigma is much less of a technical program than it is a leadership and cultural change program. Nevertheless, most of literatures on six sigma have mainly focused on technical and tactical aspects. This paper introduces a self-assessment for six sigma initiative in a major Korean software company. The self-assessment gives a valuable clue to how to manage leadership and cultural aspects of six sigma initiative.

Purpose: The purpose of this study was to examine the causal relationships among quality of health care service, service value, satisfaction and loyalty as perceived by hospital inpatients. Methods: A survey using a structured questionnaire was conducted with 654 hospital inpatients. Analysis of the data was done with both SPSS Win 17.0 for descriptive statistics and AMOS 18.0 for the structural equation model. Results: The modified model yielded Chi-square=7.96 (p=.019), df=2, $x^2$/df=3.98, GFI=.99, AGFI=.96, RMSEA=.07, NFI=.99, CFI=.99, TLI=.98 and showed good fit indices. Three dimensions of quality had significant direct effects on service value. Functional quality, technical quality and service value had significant direct effects on customer satisfaction. Technical quality, service value, and customer satisfaction had significant direct effects on customer loyalty. Conclusion: These results suggest that quality of health care is an important element in service value, and through both quality and service value, customer satisfaction and customer loyalty can be enhanced. Further study with a larger sample from various hospitals and a longitudinal design is necessary.

As the Medical Serious Games are recently proven effective, the quality evaluation of the game has become an important issue. In quality evaluation, objective criteria and evaluation elements are important. Quality evaluation of the serious game is divided into two areas : the technical (from the point of view of Program) and the non-technical (from the point of view of Content). In this study, we developed the quality evaluation element of the non-technical area to the psychotherapy and the health & rehab game according to developing process of quality evaluation model. We extracted five evaluation elements from the two kinds of medical games, and interviewed with medical experts in order to ensure the validity of them. The goodness of fit tests for the elements mentioned above were verified by conducting. Chi-square test results for the two groups did not differ significantly. In conclusion, we expect to take advantage of the results of this study to design and develop serious games for medical treatment.

Purpose: Research focuses on private universities' professional education in a competitive educational environment. Due to increased competition in the higher education industry, private universities are under pressure to improve their marketing strategies and better understand their prospective students. This study intends to investigate how information sources are used and modified by Indonesian university students when making decisions. Research design, data and methodology: This research is a case study in Riau province, which includes active university students registered in the government database. Data was collected using a questionnaire distributed via Google Forms to students at a private university, and 164 students completed the questionnaire. Results: The results show that the influence of technical quality, functional quality, and image cannot affect word of mouth, and technical quality cannot affect consumer attitudes. The results show that the distribution of high service quality and high image will encourage people to share their experiences by word of mouth to build evaluation attachment in college selection. and found that a good campus image has no direct impact on word of mouth. The spread of an excellent campus image only attracts students to evaluate it. The more talk about the distribution of service quality, the higher the decision to choose the service.

An Application of Experimental Designs to Improve the quality of Industrial product : optimization Methodology of statistical model. The primary object of this paper is to aid scientists and Engineers, in applying response surface procedures to obtain operating conditions for many technical fields, particularly for industrial manufacturing processes. The problem considered in this paper is to select technically and scientifically some important factors affecting the quality of products through the experimental design and analysis of response surface. Even though the mathematical model is unknown these statistical analysis can be applicable to control the quality of industrial products and to determine optimum operating conditions for many technical fields, particularly, for industrial manufacturing processes. This paper proposes a method to obtain the optimum operating condition, and how to find the condition by using table of orthogonal array experiments, and optimization methodology of statistical model.

The print quality of a ink jet printer is generally affected by three major components of the printing process: printer, ink formulation, and paper. The result of this study indicated that the surface sized paper with oxidized starch and cationic starch differed ink jet print quality in terms of ink spread and black optical density of the print image. Paper properties, like air permeability and siting degree, which may influence the ink jet printing were also measured. It was found that black print quality was controlled by starch level and ionic charge on the paper surface. Cationic surface sizing starch improved black ink jet print quality.

The paper discusses the combined use of softwood and eucalyptus kraft pulps in the production of printing and writing papers. Looking for process and paper quality optimization, refining pilot plant trails were carried to identify the effects of refining type (mixed or separate) and intensities (specific edge load), and also furnish composition (amount of each pulp in mixture) on final paper quality and process costs. The basic effects on pulp fibers were evaluated against paper quality properties, such as physical strengths, bulk, vessel picking, opacity and porosity, as well as the interactions with papermaking process, such as estimates of paper machine runnability, paper breaks and industrial refining control. The results show that the furnish composition and the type of refining has a significant effect on properties related with both final paper quality and total costs. The best alternative for printing and writing papers was identified for mixed refining, under the lowest refining intensity, and with the highest dosage of eucalyptus pulp.

Determining the optimal levels of the technical attributes (TAs) of a product to achieve a high level of customer satisfaction is the main activity in the planning process for quality function deployment (QFD). In real applications, the number of customer requirements for developing a single product is quite large, and the number of converted TAs is also high so the size of the house of quality (HoQ) becomes huge. Furthermore, the TA levels are often discrete instead of continuous and the product market can be divided into several market segments corresponding to the number of HoQ, which also unacceptably increases the size of the QFD optimization problem and the time spent on making decisions. This paper proposed a genetic algorithm (GA) solution approach to finding the optimum set of TAs in QFD in the above situation. A numerical example is provided for illustrating the proposed approach. To assess the computational performance of the GA, tests were performed on problems of various sizes using a fractional factorial design.
