From March in 1991, central photorefractive keratectomy(CPRK) have performed to correct the 700 myopic eyes. With the example of 310 eyes posibly observed over 6 months after CPRK, studed whether it was corrected by retrospective examining. Especilly in the study of 150 patients collected by answering sheet then studied how discomfort they took through complication, and analyzed the cause of change and Indivisual degree of sansfaction with their myopic degree and postoperative permd. This study led to a conclusion that the milder myopia and the longer postoperative period, the more patients sansfaction increased. This is because the change of refractive power become stable and corneal haze decresase with time, Futhermore we dunk that corneal haze and regression occur more frequently in higher myopla, The CPRK is promising surgical treatment for patients with higher myopia but considerable further investigation and longer-term studies are needed to increase satisfaction.

PURPOSE: The purpose of this study was to understand depression in women with endometriosis and to identify the factors influencing depression. METHOD: The instruments used were the Beck Depression Inventory for depression, Lemaire Scale for endometriosis syndrome, Mishel Uncertainty in Illness Scale-Community form (MUIS-C), the Rosenberg Self-esteem Scale, and Quality of Life (Endometriosis Health Profile Questionnaire; EHP-5) by Jones et al. The Subjects of Study were 118 outpatients diagnosed with endometriosis from 7 hospitals in Busan City and Kyungsangnam-do. Data was collected from Aug 1, 2004 to Jan 31, 2005. For statistical analysis of collected data, frequency analysis, analysis of variance, and stepwise multiple regression analysis were used with the SPSS statistical program. RESULT: The general characteristic showing a statistically significant difference in depression in the women with endometriosis was marital status. The score of the depression showed a significantly positive correlation with the score of endometriosis TSD(r= .464, p= .000), uncertainty(r= .393, p= .000), and quality of life(r= .543, p= .000). Depression showed a significantly negative correlation with the score of self esteem(r= - .557, p= .000). Stepwise multiple regression analysis revealed that the most powerful predictor of depression in the women with endometriosis was self-esteem (R2=0.311). A combination of self esteem, quality of life, and total symptom distress accounted for 50.0% of the variance in depression in women with endometriosis. CONCLUSION: The influencing factor on depression in women with endometriosis was self- esteem, quality of life, and endometriosis TSD. Further studies need to be done to identify methods of overcoming and the presentation of depression in endometriosis.

Background: Desflurane, a fluorinated methyl-ethyl ether, has some advantageous properties including low blood solubility, stability in soda lime, and resistance to biodegradation. Desflurane in vivo has demonstrated myocardial depressant property. The purpose of this study was to test the direct effects of desflurane on myocardial contractile function and coronary flow in the isolated heart. Methods: Twelve isolated rat hearts were continuously perfused with modified Krebs solution containing 6, 9 and 12 vol% of desflurane for 10 min at each concentration. Systolic left ventricular pressure and rate of change of ventricular pressure (dp/dt) were measured. Heart rate and coronary flow were also measured. To differentiate direct vasodilatory effect of desflurane from an indirect metabolic effect due to autoregulation of coronary flow, oxygen delivery, myocardial oxygen consumption and percent oxygen extraction were calculated. Results: Heart rate (control 266+/-22 beats/min) decreased to 250+/-23 beats/min at 6 vol%, 236+/-26 beats/min at 9 vol% and 223+/-22 beats/min at 12 vol% of desflurane. Systolic left ventricular pressure and dp/dt decreased in a concentration-dependent manner. In spite of decrement of myocardial oxygen consumption, coronary flow (control 12.0+/-1.2 ml/min) increased to 12.8+/-1.6 ml/min at 6 vol%, 12.9+/-1.6 ml/min at 9 vol% and 13.7+/-1.4 ml/min at 12 vol% of desflurane. Oxygen delivery increased proportionally with coronary flow. Percent oxygen extraction decreased in a concentration-dependent manner. Conclusion: These results suggest that desflurane has a direct myocardial depressing and coronary vasodilating effect in a concentration-dependent manner.

Objectives: This study examined ways to promote desirable eating habits by choosing foods with low sugar contents and provide nutrition education in adolescents. Methods: This study was a cross-sectional survey. The sugar reduction perception and knowledge, sugary food preference, and intake frequency of 487 male and female high school students in Incheon were analyzed comparatively. Results: Approximately 94.9% and 94.5% of the subjects were unaware of the promotion of a sugar reduction policy and the sugar reduction in the basic guidelines for school meals, respectively. Approximately 95% of them had not received any sugar reduction nutrition education, and 90% were not interested in sugar reduction. The perception for sugar reduction was significantly higher in girls (3.43 out of 5 points) than in boys (3.16 out of 5 points) (P < 0.001). Knowledge about sugar was 3.65 out of 6 points in girls and 3.04 points in boys (P < 0.001). The preference and intake frequency for fruits of the total students were 4.24 out of 5 points and 2.56, respectively.For beverages, the preference was significantly higher in boys (3.97 points) than in girls (3.70 points) (P < 0.001), and the intake frequency was significantly higher in boys (2.26 points) than in girls (2.08 points) (P < 0.001). The preference for snacks was significantly higher for girls (4.19 points) than boys (4.02 points) (P < 0.01), and the intake frequency was 2.22 points in boys and 2.17 in girls, showing no significant difference. Sugar reduction perception and knowledge about sugar showed significant negative correlations with the snack intake frequency (r = -0.11, P < 0.05; -0.13, P < 0.05) after adjusting for gender, grade, and body mass index. Conclusions The high school students' perception of sugar reduction was very low, and there was a significant correlation with sugary food intake, suggesting that the sugary food intake will decrease as the sugar reduction perception and knowledge about sugar increase.

Authors performed extrapedicular screws fixation in thoracic spines. Because patient had very narrow thoracic pedicles, classical transpedicular screws fixation could not be accomplished. In case of narrow thoracic pedicles, extrapedicular screws fixation would be a good alternative technique. We describe here a method for thoracic extrapedicular screws fixation.
