This descriptive, correlational study was carried out in order to a) investigate the perceived stress and quality of life, b) to identify the relationship between the stress and quality of life of recipients who have undergone kidney transplantation and c) to provide data for their care in clinical situations. The subjects in this study were 156 kidney transplant recipients who received regular follow up in the Out Patient departments of 9 university hospitals in Seoul and the Provinces. The data were collected during the period from June 2 to August 31, 1998. The instruments used for this study were as follows: The Stress instrument used in this study was a stress questionnaire in which I modified the instrument developed by Hayward(1989), KTRSS(Kidney Transplant Recipient Stress Scale) and used by Fallen(1997). The instrument to measure the Quality of Life in this study was the 'Quality of Life Scale developed by Ro You Ja The data was analyzed by the SPSS program using descriptive statistics & Pearson's correlation coefficient. The results were as follows 1. The range of stress the scores of the subjects was from 62 to 163. The mean score was 115(SD=20.609). Perceived stress revealed the mean, 3.05(SD=0.552) ranged from 4.288 to 1.660 Among 38 items, the highest mean in the rank-order was "Taking medications for the rest of their lives"(M=4.288, SD=0.908). The next four stressors in the rank-order were "Fear of injury to the new kideney, Fear of rejection, Cost of medication, Uncertainty about the future".The item with the lowest(M = 1.660,SD=o.853) was "Non-reliance on nursing staff". The next was "Non-reliance on medical staff". 2. The range of Quality of Life scores of the subjects was from 83 to 200. The mean score was 151.237 (SD= 22.296) For each factor on the Quality of Life scale, the mean scores in the rank-order were as followed: Family relationship : 3.518(SD=0717), Self-esteem 3.550(SD=0.760), Relationship with neighbors : 3.430(SD=O.522), Physical state and function : 3.290(SD=0.549), Emotional state 3. 199(SD=0.663) 3. The relationship between stress and the Quality of life revealed a significant negative correlation (r=-0.430, p= .000). The relationship between stress and other factors in the Quality of Life scale showed a negative correlation, as follows: Stress and emotional state : r=-0.432, p=.000, Physical state and function : r=-0.403, p=.000, Economical state : r= -0.330, p=.000, Relationship with neighbors : r= -0.290, p=.000, Self esteem: r = -0.205, p = .010, Family relationship :r=-0.264, p=.001 In conclusion, This study revealed that the perceived stress and Quality of life of Kidney Transplant recipients have significant correlation. The results of this study might help Nurses and other health care workers to consult effectively, to educate, to give pre operational information, to prepare education for the period following the discharge, and to develop interventions for self-care reinforcement.

BACKGROUND: The pathogenic role of the hair follicle mite in rosacea is still a matter of debate. Although the hair follicle mite may induce a pathologic condition by dermal invasion or excessive number of mites, the number of mites necessary to induce a pathologic condition has not been established in Korea. OBJECTIVE: The purpose of our study was to know the causative role of the hair follicle mite in rosacea and the threshold value between 'normal' and 'abnormal' density of the hair follicle mite on Korean facial skin. METHODS: We applied skin surface biopsy to investigate the population density and distribution of hair follicle mites in the facial skin of 50 patients with rosacea (9 with episodic erythema, 29 with stage I, 12 with stage II), 7 patients with demodicidosis and 54 control subjects. The mites were counted in measured skin surface biopsy specimens obtained from three standard facial sites(2cm on cheek and chin, 1cm on nose) with cyanoacrylate glue. RESULTS: 1. The mean mite count per 5cm was 3.4+/-0.7 in control subjects and 10.7+/-1.9 in patients with rosacea(p<0.05) The density of Demodex(mite count/ 5cm) was significantly higher in patients with demodicidosis (115+/-14.2) than in the control (p<0.001) and rosacea patients(p<0.05). 2. The highest density of mites was found on the cheek in the control and diseased subjects. The incidence of hair follicle mites was higher on the nose than on the cheek in the control subjects and rosacea patients. In demodicidosis, the incidence of the hair follicle mites was higher on the cheek than on the nose. 3. The distribution of hair follicle mite was not significantly different among the three clinical stages of rosacea. The mite counts in stage II rosacea were higher than those of control subjects (p<0.05). 4. The distribution of the hair follicle mite in the control subjects was related to a increase of age but not related to sex. The distribution of the hair flooicle mites in rosacea patients was not related to age or sex. 5. Hair follicle mites were found in 33 out of 54 control subjects(61%) and in 40 out of 50 rosacea patients (80%). The mite counts of all control subjects and all rosacea patients were less than 5/cm and 10/cm, respectively. The mite counts of all demodicidosis patients were more than 10/cm. CONCLUSION: These results suggest that the increased nomber of mites play a part in the pathogenesis of rosacea and demodicidosis is a specifio disease entity differentiated from rosacea. When the density of the hair follicle mites is above 5 /cm2, a pathologic condition of the skin, such as rosacea and demodicidosis, would have to be considered. Demodicidosis should be suspected when the density of the hair follicle mites is above 10 /cm. In addition, skin surface biopsy is recommended as the most simple and useful clinical method in search of the distribution of the distrbution of the hair follicle mites.

Purpose: This study analyzed the changes in the number of surgeries and surgical patterns due to the adoption and diffusion of new medical technology while focusing on radical prostatectomy. Materials and Methods: Medical equipment status report data and the National Health Insurance claims data from 2007 to 2019 were used. A total of 62798 radical prostatectomies from 135 medical facilities were analyzed. Radical prostatectomy was classified into open radical prostatectomy (ORP), laparoscopic radical prostatectomy (LRP), and robot-assisted laparoscopic radical prostatectomy (RARP) using the fee schedule codes. A linear mixed model was used to determine whether the adoption of a robotic surgical system had an effect on the number of surgeries and surgical patterns after adjusting for medical characteristics. Results: The number of radical prostatectomies performed in Korea increased from 1756 in 2007 to 8475 in 2019. During this period, the proportion of RARP in total surgery increased from 17.5% to 74.3%. The mean number of surgeries at medical facilities adopting the robotic surgical system was 128.3, which was higher compared to 18.5 cases in medical facilities that did not adopt it. The adoption of a robotic surgical system increased the number of radical prostatectomy surgeries by 12.1 cases and the RARP share by 47.2% in a linear mixed model.  Conclusion The adoption and diffusion of robotic surgical systems in Korea increased the number of surgeries as well as the share of robotic surgery. It is necessary to manage a technology that is widely used in a state where its clinical effectiveness is uncertain.

Urinary retention is a common complication after abdominal surgery. Urinary retention causes infection and damage to the urinary system, prolonging hospital stays and increasing health care costs in the end. Because medical personnel tend to regard urinary retention as not being a serious problem, it is hard to find any method which decrease the postoperative urinary retention. There are few papers reporting the incidence and the factors which influence the postoperative urinary retention. The purpose of this study is to evaluate the incidence of postoperative urinary retention and to identify the factors which affect the postoperative urinary retention. We retrospectively reviewed 296 patients out of 338, who had been undergone laparotomy under spinal or general endotracheal anesthesia during a three month period from January to March 1998. We reviewed nursing, anesthetic and operative records. Among the 296 patients, male were 189(63.9%) and female were 107(36.1%). Postoperative urinary retention occurred in 71 patients(24%). The incidence rate was higher in female patients than in male (M : F=18% : 35%). Factors that in fluence the incidence of postoperative urinary retention were sex, duration of operation, the amount of fluid given the patient, preoperative history of dysuria, and preoperative insertion of a urinary catheter. Among those factors, preoperative urinary catheter insertion is the most effective preventive measure in lowering the incidence of postoperative urinary retention (Spearman correlation coefficient, r=-.462). Shortening the operation time and sparing the fluid which is infused during operation are important in preventing postoperative urinary retention. Preoperative urinary catheter insertion may be helpful in lowering urinary retention in those patients who have a possibility of postoperative urinary retention.
