This study is (a) to describe the history of Total Quality Management (TQM) generated in the industry, health care service, and nursing society ; (b) to define the concept, total quality management including the definition of quality ; (C) to explain the each principle of TQM theory developed by main theorists, E. Deming, J. Juran, and B. Crosby ; (d) to give the examples related to TQM implementation at the health care organization ; and (e) to mention the extent to which the health care organizations are able to evaluate their cultural organization toward TQM and have had the way to measure the effect of TQM implementation. TQM referred to Continuous Quality Improvement(CQI), Quality Improvement(QI), and Total Quality Improvement(TQI), was not recognized by experts in the United States industry, but by economists in Japan until the end of the 1970's. However, the United States' government led to introduce the principles of TQM to general industry as well as health care service area so that TQM became a main philosophy to manage the organizations in health care service. TQM is a structured, systematic process for creating organization-wide participation in planning and implementing continuous improvement in quality. E. Deming established the "Chain reaction in Quality" and the fourteen point of TQM. The Chain reaction in quality is to describe the relationship among the reduction of waste, rework, and delay, quality improvement, customer satisfaction, and productivity. There are fourteen points to explain the principles of TQM by E. Deming. Juran defined the "Quality Trilogy" to improve the level of quality in any organization. Quality Trilogy has three steps such as quality planning, quality control, and quality improvement for implementing the TQM projects. Crosby describes his TQM theory by establishing "Four Absolutes" and "Fourteen steps in TQM" implementation. Until now, most healthcare organizations have made efforts to organize the TQM task team and to implement TQM principles with various issues. There are three priorities to select the TQM issues : High-volume, High-risk, and Problem-prone. However, there is no absolute, credible measurement yet to evaluate the effects of TQM implementation in health care organization regardless of the classification of health care organizations, geographical background, and social influence. Thus, developing the evaluation way in terms of TQM is the foremost task in health service area. The most important thing for TQM implementation in the organization is to settle up the concept, cultural transformation from traditional management toward quality.

Community-Based Participatory Research(CBPR) has gained attention as a public health approach to develop community health interventions to address health disparities in recognition of the community relevance of specific health issues associated with social determinants of health. It emphasizes community involvement in equal partnership with researchers and public health professionals to address community-identified needs. The characteristics and principles of CBPR discussed in this paper highlight participatory nature, capacity development, partnership building, and process-orientation of CBPR. A 6-step process model for community empowerment is then introduced as a CBPR operationalization strategy. Mixed methods research approaches are valuable in CBPR as well as process evaluation. For the application of CBPR in Korean contexts, the Diffusion of Innovation theory is suggested as a theoretical framework for implementation. Building public health partnerships between public and private sectors to create partnership synergy is a necessary condition for successful CBPR for health promotion in Korea. Accompanying critical factors for the CBPR application include: common understanding of CBPR and its values, establishment of the definition of 'community,' 'community-based' and 'participation' in community health, development of accommodating research infrastructure for CBPR, recognition of the importance of program evaluation (particularly process evaluation), and training CBPR specialists.

Objectives : The purpose of this study was to analyze dental records performed through a dental hygiene process and provide basic data on clinical training education for dental hygienists. Methods : The dental hygiene records of 440 senior dental hygiene students in Y University from March 2005 to September 2008, were examined. The needs of the clients confirmed by the dental hygiene diagnosis was based on Human Need Theory. The client's needs and the number of visits were analyzed according to the general characteristics(gender, age). The contents of the dental hygiene implementation performed according to the needs were divided into dental hygiene care and oral health education. The dental hygiene evaluation was classified into 'Met of Goal', 'Partially Met of Goal', and 'Unmet of Goal' according to the dental hygiene diagnosis. Data analysis was performed for the Frequency statistics and a Fisher's exact test using SPSS 12.0K for Windows. Results : 1. The clients were mostly aged in their 20's(307 clients). 2. The dental hygiene care usually performed was 'Scaling' and 'Recommendation to visit a dental clinic', and the education performed was 'How to brush teeth'. The implementation result from the need to Freedom of Stress was as simple as 'Be careful when treating' and 'Explanation of medical treatment and tools'. 3. The dental hygiene evaluation showed a higher met rate in the field of education than in that of the dental hygiene care. The reason for unmet the goal was 'Lack of the client's efforts and they didn't visit dental clinic'. Conclusions : The search for a range of clients for dental hygiene process should be made through effective connections between the local community institutions and schools. It was suggested that they should be strength the practical exercises for clients suffering dental anxiety and stress in dental treatments. In addition, education and attempts to motivate the clients should be performed according to their characteristics.

In this study, we investigated how to achieve differentiation for the ISM (Internet Shopping Mall) to improve profitability, which is required for survival in the fiercely competitive ISM industry. We analyzed implementation level key managerial factors that could contribute to the differentiation of the ISM. The research model is constructed through integration of two distinctive research streams of e-commerce. The one is B2C differentiation strategy research, most of which are conceptual and conducted at a strategy level, and the other is empirical research analyzing the antecedents of customer satisfaction at the ISM. This study is organized as follows. First, we draw upon transaction cost theory to organize constructs representing customer value associated with the customer buying decision process. Next, after reviewing comprehensive managerial factors that could impact on customer value, we selected 15 managerial factors that could contribute to the differentiation of the ISM to deliver value to customers. Finally, the resulting structural model is validated through empirical analyses. The results provide insights for future studies on ISM differentiation.

With growing applications of wireless video streaming, an efficient video traffic model featuring modern high-compression techniques is more desirable than ever, because the wireless channel bandwidths are ever limited and time-varying. We propose a modeling and analysis method for video traffic by a class of stochastic processes, which we call '$GEO^Y/G/{\infty}$ input processes'. We model video traffic by $GEO^Y/G/{\infty}$ input process with gamma-distributed batch sizes Y and Weibull-like autocorrelation function. Using four real-encoded, full-length video traces including action movies, a drama, and an animation, we evaluate our modeling performance against existing model, transformed-M/G/${\infty}$ input process, which is one of most recently proposed video modeling methods in the literature. Our proposed $GEO^Y/G/{\infty}$ model is observed to consistently provide conservative performance predictions, in terms of packet loss ratio, within acceptable error at various traffic loads of interest in practical multimedia streaming systems, while the existing transformed-M/G/${\infty}$ fails. For real-time implementation of our model, we analyze G/D/1/K queueing systems with $GEO^Y/G/{\infty}$ input process to upper estimate the packet loss probabilities.

Plastic molding designers are frequently faced with optimizing multiple defects in injection molded parts. these defects are usually in conflict with each other, and thus a tradeoff needs to be made reach a final compromised solution. In this study, an automated injection molding design methodology has been developed to optimize multiple defects of injection molded parts. Two features of the proposed methodology are as follows: one is to apply the utility theory to transform the original multiple objective optimization problem into single objective optimization problem with utility as objective function, the other is an implementation of a direct search-based injection molding optimization procedure with automated consideration of process variation. The modified complex method is used as a general optimization tool in this research. The developed methodology was applied to an actual molding design and the results showed that the methodology was useful through the CAE simulation using a commercial injection molding software package. Applied to production, this study will be of immense value to industry in reducing the product development time and enhancing the product quality.

In order to post process the vector-quantized images employing the theory of projections onto convex sets or the constrained minimization technique, the the projector onto QCS(quantization constraint set) as well as the filter that smoothes the lock boundaries should be investigated theoretically. The basic idea behind the projection onto QCS is to prevent the processed data from diverging from the original quantization region in order to reduce the blurring artifacts caused by a filtering operation. However, since the Voronoi regions in order to reduce the blurring artifacts caused by a filtering operation. However, since the Voronoi regions in the vector quantization are arbitrarilly shaped unless the vector quantization has a structural code book, the implementation of the projection onto QCS is very complicate. This paper mathematically analyzes the projection onto QCS from the viewpoit of minimizing the mean square error. Through the analysis, it has been revealed that the projection onto a subset of the QCS yields lower distortion than the projection onto QCS does. Searching for an optimal constraint set is not easy and the operation of the projector is complicate, since the shape of optimal constraint set is dependent on the statistical characteristics between the filtered and original images. Therefore, we proposed a hyper-cube as a constraint set that enables a simple projection. It sill be also shown that a proper filtering technique followed by the projection onto the hyper-cube can reduce the quantization distortion by theory and experiment.

For the last half-century, interprofessional education (IPE) has been identified and discussed as a critical educational process to facilitate collaboration in order to improve healthcare outcomes for healthcare participants. While the concept is not new, outcome-based research has provided few valid and reliable explanations of whether and how IPE can be effective in healthcare quality improvement. This challenge stems from the struggle to understand the epistemological meaning of IPE. The purpose of this literature review paper is to provide a synthesized understanding of IPE, its meaning, and to provide practical guidance for medical educators. The paper reviewed several key aspects of IPE. Professionalility was discussed to understand the historical background of IPE, followed by an explanation of the international trend of embracing the complexity of health care practice and the need for interprofessional collaboration. Additionally, several theoretical perspectives, such as general systems theory, social identity theory, and community of practice were reviewed to pinpoint what constitutes IPE. Several existing definitions were discussed with similar concepts (i.e., disciplinary vs. professional, and multi-, inter-, vs. trans-) to clarify the nature of knowledge and collaboration in IPE. Three concepts, including practice, authenticity of context, and socialization were proposed as key constructs of IPE, followed by appropriate timing of IPE, outcome research, directions for future research, and guidance for implementation. Community-based medical education practice, professional socialization within a community, and longitudinal system-based outcome research are recommended as future directions for research and practice.

Purpose: The study aims to assess the current status of domestic public food delivery apps and analyze the process through which sellers choose between private delivery apps and public delivery apps. This involves exploring strategiesto achieve the original purpose of public food delivery apps, which is to enhance the small business owners income and promote consumer welfare by preventing the monopoly of private food delivery apps. Research design, data and methodology: the research methodology is based on a model that introduces adjustments for non-economic effects, considering the preferences of multi-homing consumers, to more realistically reflect the benefits of sellers' choices. For data analysis, real business performance data from 'Daeguro', 'Meokkaebi', and 'Somunnan Shop' were used. Results: The study revealed that if the market share of public delivery apps within a specific region increases beyond a certain level, the benefits for small-business sellers also increase. This leads to the strategic advantage of simultaneously using both delivery apps. Furthermore, the results exhibit a tendency similar to real social phenomena. Conclusions: This analysis confirmed the role of public food delivery apps in the domestic delivery app market and presents policy recommendations, including application integration and the implementation of exclusive public interest functions, to effectively fulfill this role.
