Polysomnography is an essential methodology for diagnosing and following up sleep disorders and doing researches on human sleep. Sleep medicine, mainly with the utilization of polysomnographic techniques, has developed itself as one of the promising fields in the 21st century medicine. Korea is not an exception in importing and developing sleep medicine into the conventional medicine. However, it still remains to be clarified what polysomnography is for and how it should be done, considering the relatively recent introduction of sleep medicine into Korea. The author, being a board-certified sleep medicine specailist, having experienced spreading out sleep medicine within Korea for the past four years, and having recently set up a major sleep study facility in Korea at Seoul National University Hospital, attempts in this introductory critical article to review the essential issues related to quality assurance in polysomnographic study of human sleep. Also, unconditional introduction of "automated" sleep scoring system, which has been found to have significantly reduced reliability in various studies including the author's own, is critically reviewed. The author suggests that quality assurance and training program should be initiated and established by a responsible sleep medicine-related organization such as the Korean Association of Sleep Medicine and Psychophysiology.

Korean health insurance has adopted preliminary DRG payment system through 8 DRGs from 1997. But present DRG payment system gives economic incentives for hospitals to hire less nurse. This study was attempted to develope DRG adjust index to differentiate DRG price by nurse staffing level for nursing care quality. Method: We analyzed inpatient care cost by medical institute and developed DRG adjust index to differentiate DRG price by nurse staffing level. Results: Among same medical institute, inpatient care cost are very different according to hospital's nurse staffing level. In the case of casarean section, inpatient care cost of the 1st grade general hospital are more expensive 85,732won than the 6th grade hospital. The cost difference are 8.24% of total casarean section DRG price and 16.48% of DTG variable price. We developed DRG adjust index-a to apply DRG variable price and index-b to apply DRG total price for compensation cost difference of hospitals. Conclusions: DRG price adjust index will give economic incentive for hospitals to hire more nurse and improve nursing care quality.

The purpose of this study is ultimately to contribute to enhancing quality of patients' life, by grasping quality level of care-giving service that is recognized by inpatients of long-term care hospital, and by pursuing a plan for improving quality of care-giving service based on this. For this, targeting 500 patients who entered 40 long-term care hospitals in Daejeon Metropolitan City, the quality of service was multi-dimensionally grasped by using SERVQUAL scale. As a result of research, the quality of care-giving service, which is recognized by patients as survey subjects, tended to be relatively high with about 4 points as a whole out of 5-point perfection. By item, reliability was indicated to be the highest with 4.56 points. The next was surveyed to be in order of tangibility, empathy, responsiveness, and assurance.

The purpose of this article was to review the basic concept of the SERVQUAL scale and to evaluate its usefulness in health care settings. The SERVQUAL scale was developed by Parasuraman et al. in 1988. Its purpose was to provide an instrument for measuring the quality of service that would apply across a broad range of services with minor modifications in the scale. The SERVQUAL scale is based on gap theory, which indicates the difference between consumers' expectations and their assessment of the actual performance of a specific firm. It has five dimensions to define service quality. These dimensions include: (1) tangibles' (2) reliability' (3) responsiveness' (4) assurance' (5) empathy. While the SERVQUAL scale has been tested in a number of health care settings. the findings have been mixed. So. health care marketers should be cautious in their use of the SERVQUAL scale. However, it is rare to find instruments that are as well validated as SERVQUAL appears to be. As well the SERVQUAL scale provides valuable information about the quality of health care service.

3-dimensional information for anatomic stucture plays a role as integral part in clinical aspect of dental practice. CBCT(cone beam computed tomography) has been accepted as useful diagnostic tool offering Volume data and images for evaluating teeth and jaws in lower radiation dose than conventional CT. CBCT equipment is essential for the quality assurance of it to ensure continued satisfactory performance and result of adequate images. Dental practitioner and oral and maxillofacial radiologist should have a responsibility and critical thinking to deliver this technology to patients in a responsible way, so that diaganostic value is maximised and radiation doses kept as low as resonably achievable. CBCT imaging modality should be used only after a review of the patient's health and imaging history and the completion of a thorough clinical examination. Clinical guidelines are systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances Dental practitioners should prescribe CBCT imaging only when they expect that the diagnostic yield will benefit patient care, enhance patient safety or improve clinical outcomes significantly. Knowledge of patient dose is essential for clinicians who are making the decision regarding the justification of the exposure. There are some limitation in the measurement of patient dose in CBCT for the approval and adaptation of conventinal methodolgy in CT. It is also important to ensure that doses are optimised and in line with any national and international guidelines. The higher radiation doses of CBCT compared with conventional radiography, mean that high standards must be maintained. The Quality Assurance(QA) programme should entail surveys and checks that are performed according to a regular timetable. QA programme should be maintained by staff to ensure adherence to the programme and to raise its importance among staff.

This study was conducted to identify the current situation of home care nursing research and to propose future research in the area of home care nursing in Korea. The design was a retrospective descriptive study based on 171 studies. The studies were collected from nursing academic magazines, the national library web site and dissertations on home care. The data were classified according to the independent and dependent variables which were represented in the research title. The final category classification was defined by considering the research objectives and content as found in the 171 studies. Eight categories were created to describe the results of home care nursing research in Korea. They included: home care needs. home care services. home care costs. development of home care programs and equipment. management of home care services. effectiveness of home care services, development of an educational curriculum for home care, and recognition of home care services. Based on our research we have identified other future research areas that need to be developed such as community needs assessment, standards and guidelines for home care nursing, quality assurance and quality improvement for controlling home care quality, home care informatics. and a system of home care cost and ethics.

The purpose of the study is to evaluate the visiting nurses service of a public health center. Data were collectd from the 36 clients who received services from a public health center. In terms of the process evaluation, the tool is composed 4 parts, 27 items such as assessment planning, implementation, and evaluation. It was measured through the health records by 2 peer review. In terms of the outcome evaluation, the level of client satisfaction was measured by self report or interview by 2 supervisor. The result were as follows: 1. 30% of 36 health records showed narsing process was not and out of them, nursing care plann including spectific activities were rarely established or unclear. 2. The lack of systematic data collection' showed and nursing diagnosis was not adressed in health records review. 3. Client satisfaction score was 32, 97, out of maximum score 36. 4. The lack of sufficent objective data, care plan, record of client's health status change, and evaluation was founded therefore quality assurance for visiting nurses service and in-service education are required and the development of standardized record system need.
