Purpose: This study was performed to give direction to quality improvement strategies of nursing services by comparing the differences in quality perceptions and satisfaction for nursing services between patients and nurses in small-medium sized general hospitals with 200 beds. Method: The subjects, who were 150 inpatients and 162 nurses of 4 general hospitals in a community, answered a self-report questionnaire with a SERVQUAL scale. Result: There were differences between patients' and nurses' expectations and perceptions of nursing service and satisfaction. In the service expectation, the highest factor was 'the responsiveness', and in the perceived performance, the highest was the 'assurance'. In addition, overall patients' perceptions on nursing services showed higher than nurses'. There were positive correlations among the expectations and perceptions on nursing service, and satisfaction. The correlation between perception and satisfaction was higher than the correlation between expectations and satisfaction. Conclusion: To improve the nursing service quality at small-medium hospitals, strengthening the 'assurance' factor and improving the nursing service support system is needed. Also, this study on nurses' perceived nursing service at small-medium sized hospitals should be duplicated.

Since the pilot program for a DRG-based prospective payment system was introduced in 1997, the performance of KDRGs has been one of hotly debated issues. The objectives of this study are to refine the classification algorithm of the KDRGs and to assess the improvement achieved by the refinement. The U.S. Medicare DRGs version 17.0 and the Australian Refined DRGs version 4.1 were reviewed to identify areas of possible impro-vement. Refined changes in the classification and result of date analyses were submitted to a panel of 48 physicians for their reviews and suggestions. The refinement was evaluated by the variance reduction in resource utilization achieved by the KDRG The database of 2,182,168 claims submitted to the Health Insurance Review Agency during 2002 was used for evaluation. As the result of the refinement, three new MDCs were introduced and the number of ADEGs increased from 332 to 674. Various age splits and two to four levels of severity classification for secondary diagnoses were introduced as well. A total of 1,817 groups were defined in the refined KDRGs. The variance reduction for charges of all patients increased from 48.2％ to 53.6％ by the refinement, and from 65.6％ to 73.1％ for non-outlier patients. The r-square for length of stays of all patients was increased from 28.3％ to 32.6％, and from 40.4％ to 44.9％ for non-outlier patients. These results indicated a significant improvement in the classification accuracy of the KDRG system.

The purpose of present study is to investigate the significance of preoperative evaluation with perfusion lung scintigraphy in patients with lung cancer. Lung scans with the use of macroaggregated human serum albumin labeled with technetlum-99m were carried out in 35 patients with lung cancer before thoracotomy at Seoul National University Hospital during the period from November 1981 to September 1983. The relationship between size of the perfusion defect as seen by perfusion lung scan and size of the mass lesion as seen radiologically was correlated with the presence of regional adenopathy and resectability. Among patients with a larger perfusion defect than mass lesion on chest X-ray film.86% were found to have regional lymph node involvement with 29% resectability, whereas among patients in whom a larger defect was not present only 14% had such extension of the disease with 93% resectability. The relative pulmonary arterial perfusion of affected lung was calculated from the counts of radioactivity recorded from affected lung on both anterior and posterior scans expressed as a percentage of the total counts in the scan. The mean relative pulmonary arterial perfusion of the inoperable group [34\ulcorner%] is significantly different from both that of the pneumonectomy group [39\ulcorner%] and that of the lobectomy group [48\ulcorner%].(p<0.01)

Background: This study was to investigate the effect of cervical HVLA technique and mulligan MWM technique on patients with lateral epicondylitis. Methods: 36 participants were randomly allocated to the two groups; group I involved high velocity low amplitude (HVLA) cervical mobilization technique, mulligan mobilizations with movement (MWM) technique (n=18). group II mulligan MWM (n=18). Patient attended for three times a week for six weeks. Results: The change of visual analogue scale (VAS) was statistically and significantly decreased in both of the group I and the group II. The change of patients rated tennis elbow evaluation (PRTEE) was statistically and significantly decreased in both of the group I and the group II. The change of pressure pain threshold (PPT) was statistically and significantly increased in both of the group I and the group II. Nevertheless, There is no statistical differences between group I and group II. Conclusion: After experiment, pressure pain threshold and visual analogue scale, patients rated tennis elbow evaluation were improved in both group. But Cervical HVLA group does not showed the change better than mulligan MWM group.

Background and Objectives : Patients with so-called 'functional voice disorders' who have structurally normal larynges and demonstrate muscle misuse in the larynx, and those with several interacting causes including habitual muscle tension, are probably better defined as having a 'muscle misuse voice disorder'. The purpose of this study was to analyze the voice and effectiveness of voice therapy in patients with functional voice disorders and to provide a guide for the treatment of functional voice disorder. Materials and Method : The records of 35 patients, presenting with functional voice disorder and receiving voice therapy during October, 2001 to September, 2002, were reviewed. Prior to voice therapy, the stroboscopic examination of their larynx, aerodynamic and acoustic analysis was done. The results of voice therapy were compared according to the patient's subjective, perceptual evaluation of voice, and maximal phonation time. Results : Patient's subjective, perceptual evaluation, and maximal phonation time showed superior results after voice therapy. Conclusion : The result of this study indicates that voice therapy is an effective treatment method of patients with functional voice disorder, especially muscular tension dysphonia.

Background: Sexual health and function frequently are overlooked by healthcare professionals despite being identified as an essential aspect of patient care. Patients with cancer have identified sexuality issues as being of equal importance to other quality-of-life issues. Objectives: The aim of this study was to determine the views and attitudes of oncology nurses caring for cancer patients regarding sexual counseling. Participants and Methods: A descriptive cross-sectional study was conducted on the web site of the Turkish Oncology Nurses Association. With the participation of 87 nurses from oncology departments, the study determined that most nurses do not evaluate and counsel patients regarding their sexual problems and many difficulties prevent them from focussing on sexual health. The most important reasons for ignoring sexual counseling were the absence of routine regarding sexual counseling in oncology departments, the belief that the patient may become ashamed and the nurses' self-evaluation that they have insufficient skills and education to counsel in this subject. Conclusions: The most important variables in sexual evaluation and counseling are long years of service in the profession and a postgraduate degree.

Background: In most human lives, 80 percent have problems with the ankle and can be solved with a treatment that is objective in proper assessment. Discrepacts in the ankle are also associated with walking patterns and affect hip and knee joints. An evaluation of hip flexion and extensor muscles was performed to check the strength of hip joints after ankle sprain patients application of arthesis. Methods: In the hospital in Bucheon, 20 outpatients who visited the hospital for treatment with ankle sprain were tested with 10 male and 10 female patients. The criteria for selection of the study subjects were randomly divided into those with joint movement techniques applied to the ankle joints and those with conservative physical therapy. Results: In applying arthrography and preservation physical therapy to patients with ankle sprain, a difference in muscle strength between hip flexion and extensor was noted in post-evaluation comparisons. There were significant differences in the assessment of walking speed and walking time between the two counties in the gait analysis assessment (p<.05). Conclusion: Studies have shown that applying arthrography to people with ankle sprain has a greater therapeutic effect than using conservative physical therapy.

Palatoplasty using Furlow's double-opposing Z-plasty has been performed from June, 1995 to September, 1999 at Seoul National University Children's Hospital. The goal of this study is to determine the optimal timing of repair and cleft severity affecting velopharyngeal function. This is the retrospective study of patients operated by the second author. The mean age of patients was 10.53 months. The patients could be divided into three groups-isolated cleft palate(n=70), unilateral cleft lip and palate(n=88), and bilateral cleft lip and palate(n=42). To evaluate the velopharyngeal function, we used two parameters, speech evaluation and cineofluorography using DSR(digital subtraction radiography). Also, to determine the relevance between cleft severity and speech development, we measured the distance between maxillary tuberosities and cleft margins. Among 200 patients, about 96% had no or minimal hypernasality and 87% had no or mild nasal emission. The cleft width and length of soft palate seemed not to be related with the speech development. Palatoplasty at the age under 12 months resulted in less 'nasal emission' and better 'articulation' of the parameters that were assessed at the age of 7 years. It can be concluded Furlow palatoplasty shows satisfactory results and also it seems that it is better to perform the operation before the age of 12 months.

Objectives: We studied what is the role of elective carotid artery resection in the management of advanced cervical metastatic cancer. Materials and Methods: 5 patients with elective carotid artery resection in advanced metastatic cervical cancer were reviewed retrospectively. The patients underwent complete neuroradiologic evaluation, including CT/MRI. angiography, duplex doppler, balloon occlusion test with EEG, and brain SPECT for determination of compatible collateral circulation after carotid artery resection. Results: Perioperative complication were appeared in 2 patients those were middle cerebral arterial infarction and mediastinal bleeding. Postoperative mortality rate was 20%. 4 patients recurred within 1 year. Conclusion: Preoperative collateral study rarely provide whether resection carotid artery or not. Elective carotid artery resection cannot provide locoregional control of tumor and don't promote survival.

PURPOSE. The study was conducted to evaluate the efficacy of implant supported tooth replacement in diabetic patients. MATERIALS AND METHODS. The study involved placement of implants (UNITI implants, Equinox Medical Technologies, Zeist, Holland, diameter of 3.7 mm and length 13 mm) in five diabetic patients (three females and two males) of age ranging from 35-65 years with acceptable metabolic control of plasma glucose. All patients included in the study were indicated for single tooth maxillary central incisor replacement, with the adjacent teeth intact. The survival of the restored implants was assessed for a period of three months by measurement of crestal bone heights, bleeding on probing and micro flora predominance. Paired t-test was done to find out the difference in the microbial colonization, bleeding on probing and crestal bone loss. P values of less than 0.05 were taken to indicate statistical significance. RESULTS. Results indicated that there was a significant reduction in bleeding on probing and colonization at the end of three months and the bone loss was not statistically significant. CONCLUSION. The study explores the hypothesis that patients with diabetes are appropriate candidates for implants and justifies the continued evaluation of the impact of diabetes on implant success and complications.
