Purpose: : This study investigated the differences in system thinking and innovative behavior among nursing students, nursing managers, and nursing educators by implementing a table-top simulation. Methods: : This study used a non-equivalent pretest-posttest design. The game-based table-top simulation, Friday night at the ER® was separately implemented to three groups including 14 nursing students (on April 13, 2021), 15 nursing managers (on April 29, 2021), and 14 nursing educators (on January 25, 2022). The system thinking scale and innovative behavior scale were used to measure the effect of table-top simulation. Wilcoxon signed rank and Kruskal-Wallis test were utilized using the SPSS program for data analysis. Results: : There was no statistically significant increase in the pre- and post-scores of system thinking in each group. However, the innovative behavior scores significantly increased in all groups after simulation. There were no significant differences in systems thinking and innovative behavior among the three groups. Conclusion : The game-based table-top simulation provides motivation for innovative behavior through communication and teamwork among team members.

A study on objective personality characteristics of 41 central serous chorioretinopathy patients was performed to investigate the etiologic relationship of psychological behaviors about the central serous chorioretinopathy. Fourty-one healthy subjects were used as a control group. Authors used the Minnesota Multiphasic Personality Inventory (MMPI) which consisted of 4 validity scales and 10 clinical scales. Three neurotic scales of hypochondriasis, depression and hysteria in the atients group were significantly higher than in the normal control group even though the mean scores on each clinical scale were within normal ranges in both groups.

PURPOSE: Strabismus fixus is a rare form of strabismus which is known for its difficulty to correct surgically, because it tends to go back to its previous state after the surgery. We report the case because we had successfully corrected the case of convergent strabismus fixus. SUBJECTS AND METHODS: A 38-year-old female patient who had both medial rectus muscle tenotomy 10 years before was operated with both lateral rectus muscle resection, superior and inferior rectus muscle recession and temporary traction suture for 5 days, but it was dissatisfactory, so making a hole in the lateral orbital rim was performed by microdrill, with fixation of insertion site of the lateral rectus muscle to the lateral orbital rim by permanent traction suture. RESULTS: At three months after the surgery, patient appeared to be almost orthophoric at primary position. Eye movement was impossible but we had satisfactory result cosmetically. CONCLUSION: It is suggested that eyeball fixation to lateral orbital rim is an effective surgical procedure for the case of convergent strabismus fixus which was not corrected by previous surgical techniques.

Surgical method for blow out fracture of medial orbital wall is performed by medial canthotomy and subciliary incision or transconjunctival incision. However, these approaches can leave cosmetic problem due to skin incision and have a risk of infection and absorption of prosthetic implant for a large medial wall fracture. The authors performed endoscopic intranasal reconstruction of the isolated medial wall fracture in a case with significant functional impairment of extraocular muscle. After the incision of the middle turbinate, medial wall fracture was reconstructed with muco-periosteal flap under endoscopic control. We had a good result without intraoperative or postoperative complications caused by prosthetic implant. There was no disadvantage seen with the traditional approaches by medial canthotomy. Endoscopic intranasal reconstruction with muco-periosteal flap appears to be a new safe method for especially large defect.

Postoperative endophthalmitis following cataract surgery is rare but may influence the final visual outcome markedly. The authors reviewed the clinical records of 16 patients who had been treated with the diagnosis of endophthalmitis after cataract surgeries from March. 1992. to September, 1995. We analysised their final visual outcomes according to cultured microorganisms, durations of symptom onset after the surgeries, the methods of antibiotic administration and treatment methods with or without vitrectomies. Final visual accuities were 0.5 or better in 50% of all eyes, 0.15 or better in 75% and light perception or worse in 4 eyes(25%). Twelve(75%) of all eyes were cultured in positive. Five of twelve culture proven cases were Staphylococcus epidermidis and five were Pseudomonas aeruginosa. Each case of Xanthomonas maltophilia and fluorescens were cultured. All 5 cases infected by gram positive organisms had got visual accuity of 0.15 or better but 4 of 7 eyes infected by gram negative ones had got. We treated 9 patients with intravitreal, subconjunctival and systemic antibiotics but did 7 without systemic antibiotics. Six cases(85.7%) of these had got visual accuity of 0.15 or better but 6 cases(66.7%) of those had got. One of five patients who had undergone therapeutic vitrectomies had got visual outcome of 0.15 or better but all eleven without vitrectomy had got.

Ocular perforation during retinal reattachment surgery is very uncommon intraoperative complication.If globe rupture occurs, intraocular fluid leakage, ocular hypotony, and vitreous hemorrhage follow. Authors made an intraoperative ocular perforation inadvertently by scleral depressor on our patient who had a recurrent retinal detachment on his right eye. However, immediate scleral suture of the ruptured wound and balanced salt solution injection by pars plana route, and effective scleral exoplant maintained his retina anatomically flat. So, we present the case with a brief literatures review.

PURPOSE: Myelodysplastic syndrome (MDS) in children needs to be elucidated in terms of clinical characteristics, natural history, the most effective treatment and prognostic factors, as the disease is very rare and its definition and classification has not reached a consensus by many physician. This study was aimed to describe the characteristics and the disease courses of Korean children with MDS, and to analyze the usefulness of prognostic scoring systems in the prediction of transformation to acute myelogenous leukemia (AML) and overall survival among subgroups. MATERIALS AND METHODS: Fourteen children with MDS seen at Chonnam University Hospital and additional 59 patients identified by the review of Korean literature were evaluated to define clinical characteristics and disease courses. Kaplan-Meier (K-M) probability of leukemic transformation and overall survival were plotted. FAB subtypes, subgroups by Boumemouth Scoring System (BSS), and International Prognostic Scoring System (IPSS) risk groups were compared to predict transformation to AML and overall survival. RESULTS: The median age of 14 patients was 36.5 months. The sex ratio was 3.7:1 (M: F). The frequency of FAB subtypes in Korea was similar to that of other countries except for higher proportion of RA (37%). K-M 3-yr probability of AML transformation and survival for Korean patients were 54.7%, and 49.8%, respectively. Although FAB system, BMS and IPSS were all capable of discriminating subgroups in the prediction of AML transformation and survival, they did not reach the significant level possibly due to small number of patients assigned to each subgroup. CONCLUSION: The clinical characteristics of Korean children with MDS were not different from those of other countries. This study showed the high rate of AML transformation and poor survival in children with MDS.

Underserved area is a region that has a lack of healthcare resources. In the context of Korea, however, there are not enough detailed criteria for underserved areas. In this study, we aimed to develop indicators for underserved area through Delphi technique. We systematically reviewed the existing measure of underserved area. Sixty indicators were extracted as candidates across four domains in secondary medical care. Four domains are demand, medical resource, quality of care, and health outcome. To develop indicator, two round Delphi survey was conducted among 15 professional experts such as professionals and public administrators. In conclusion, 2 final indicators (accessibility, medical utilization) was determined as an appropriate measure in order to designate underserved area for secondary medical services. Using our criteria from Delphi technique, 36 areas were found as underserved areas for the secondary medical care.
