Background : This study was carried out to assess the quality improvement(QI)activities in Korean hospitals. Methods : A mailed questionnaire survey was conducted between September 15 and October 30, 2000. The staffs being charge of QI each of the hospitals with 400 beds or more responded to the questionnaire. Of the 108 hospitals eligible for inclusion in our study, 69 participated, yielding a response rate of 63.9%. Results : Based on these survey, 87.3 percent of the responding hospitals were performing QI projects and 54 percent of the hospitals had a separate department for QI activity. About 62 percent of hospitals performing QI activity (QI hospitals) had a QI manager and 58 percent had a separate budget for QI activities. Among the QI hospitals, 85 percent had cross-functional or cross-departmental teams as the major mechanisms for doing QI projects, 94 percent had one or more educational programs on QI. The level of physician's participation level for QI projects was lower than other staff(CEO, nurses and other administrators). Conclusion : The majority of the hospitals have undertaken activities in QI. For the successful implemented QI, the involvement of and education for employees(including physicians and other health professionals)are needed as well as management strategy and leadership. Understanding of other hospitals experience would be helpful for health care managers to plan and initiate QI activities.

We often overlook the importance of several safety issues such as identification of patients, timeout procedure, hand hygiene, handoff communication, and many others. This ignorance, along with many other issues, leads to medical error being ranked as a third leading cause of death in the U.S. Consequently, quality improvement (QI) has become one of the major subjects in healthcare despite a relatively short history. Improving quality is about making healthcare safe, effective, patient-centered, timely, efficient, and equitable. Understanding the need and methodology of QI as well as participation is now essential for physicians. Although basic QI methodology has not changed, one of the most fascinating changes in recent QI is conducting large-scale QI projects through multicenter networks. Prospective multicenter QI projects utilizing the Korean Neonatal Network are a substantial initiation of pediatric QI in Korea. The Korean Pediatric Society should set ambitious goals for QI activities for every primary care pediatrician and pediatric subspecialist.

Background : The purpose of this study was to investigate the understanding and the attitude of Korean hospital CEOs toward the healthcare quality improvement. Methods : A mailed questionnaire survey to the CEOs of hospitals with 400 beds or more was conducted between September 15 and October 30, 2000. Of the 108 hospitals eligible for the study, 58 participated, yielding a response rate of 54 percent. Result : The hospital CEOs have expressed that their hospital management was arduous job, and they had been pressured by increasing competitions among healthcare providers. They indicated that the low fees of health insurance made their hospital management difficult. The results also indicated that there was general consensus that the improvement of service quality was important in encouraging their organizations, but the investment of manpower and equipment ranked higher than the improvement of service quality. The majority of the CEOs have good understanding about quality improvement activities. However the facts that in general QI must be focused at the process of services and customer satisfaction, meanwhile quality improvement activities are helpful for the organizational productivity embarrassed them. The hospital CEOs responded that there were successful changes in terms of quality of care, patient satisfaction, and process efficiency after QI activities, but no increase in patient number and profit. Lack of understanding to QI activities and limited budget seem to attribute unsatisfactory outcomes. Conclusion : The majority of Korean hospital CEOs have a good understanding and attitude about QI activities. As mentioned in the result, despite of several limitations, several facts regarding the CEOs of hospital in Korean can be elucidated. (1) The general cognition of the QI project is relatively high, and it is accepted with positive concern, (2) the priority of the QI project, however, is not set higher than other projects and (3) the specific concepts of the actual QI project such as customer (patient)-focused work driving, the recognition of the work accomplishment, and the importance of rewards have not sufficiently understood.

The destruction and fracture of rock masses are crucial components in engineering and there is an increasing demand for the study of the influence of rock mass heterogeneity on the safety of engineering projects. The numerical manifold method (NMM) has a unified solution format for continuous and discontinuous problems. In most NMM studies, material homogeneity has been assumed and despite this simplification, fracture mechanics remain complex and simulations are inefficient because of the complicated topology updating operations that are needed after crack propagation. These operations become computationally expensive especially in the cases of heterogeneous materials. In this study, a heterogeneous model algorithm based on stochastic theory was developed and introduced into the NMM. A new fracture algorithm was developed to simulate the rupture zone. The algorithm was validated for the examples of the four-point shear beam and semi-circular bend. Results show that the algorithm can efficiently simulate the rupture zone of heterogeneous rock masses. Heterogeneity has a powerful effect on the macroscopic failure characteristics and uniaxial compressive strength of rock masses. The peak strength of homogeneous material (with heterogeneity or standard deviation of 0) is 2.4 times that of heterogeneous material (with heterogeneity of 11.0). Moreover, the local distribution of parameter values can affect the configuration of rupture zones in rock masses. The local distribution also influences the peak value on the stress-strain curve and the residual strength. The post-peak stress-strain curve envelope from 60 random calculations can be used as an estimate of the strength of engineering rock masses.

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.

This paper proposes gob-side entry retaining by roof break and filling in thick-layer soft rock conditions based on the thick-layer soft rock roof strata migration law and the demand for non-pillar gob-side entry retaining projects. The functional expressions of main roof subsidence are derived for three break roof direction conditions: lateral deflection toward the roadway, lateral deflection toward the gob and vertically to the roof. These are derived according to the load-bearing boundary conditions of the main roadway roof stratum. It is concluded that the break roof angle is an important factor influencing the stability of gob-side entry retaining surrounding rock. This paper studies the stress distribution characteristics and plastic damage scope of gob-side entry retaining integrated coal seams, as well as the roof strata migration law and the supporting stability of caving structure filled on the break roof layer at the break roof angles of $-5^{\circ}$, $0^{\circ}$, $5^{\circ}$, $10^{\circ}$ and $15^{\circ}$ are studied. The simulation results of numerical analysis indicate that, the stress concentration and plastic damage scope to the sides of gob-side entry retaining integrated coal at the break roof angle of $5^{\circ}$ are reduced and shearing stress concentration of the caving filling body has been eliminated. The disturbance of coal mining to the roadway roof and loss of carrying capacity are mitigated. Field tests have been carried out on air-return roadway 5203 with the break roof angle of $5^{\circ}$. The monitoring indicates that the break roof filling section and compaction section are located at 0-45 m and 45-75 m behind the working face, respectively. The section from 75-100 m tends to be stable.
