PURPOSE: This study was conducted to determine the effects of a fall prevention program on knowledge, efficacy, and prevention behavior of falls among the low-income elderly. METHODS: This study used a nonequivalent control group pre and post test quasi-experimental research design. The study was conducted from August to October, 2008 with 20 subjects in the experimental group and 22 in the control group who were registered at the public health center of S District in D City. RESULTS: Hypothesis 1 "The experimental group that participated in the fall prevention program will show a higher degree of knowledge about falls than the control group" was supported. Hypothesis 2 "The experimental group will have a higher degree of self-efficacy of falls than the control group" was not supported. Hypothesis 3 "The experimental group will report fall prevention behavior more frequently than the control group" was supported. CONCLUSION: It was verified that the fall prevention program in this study was an effective intervention to improve knowledge about falls and fall prevention behaviors among the low-income elderly. The results can be used as part of an intervention to prevent falls for the vulnerable elderly such as the low-income elderly.

PURPOSE: To evaluate the effects of trans-scleral diode laser cyclophotocoagulation (TSDLC) on best corrected visual acuity (BCVA) in patients with refractory glaucoma. METHODS: The medical records of 148 eyes of 148 patients with refractory glaucoma who were followed-up for over 6 months after TSDLC were analyzed retrospectively. Among them, 49 eyes of 49 subjects who had BCVA greater than no light perception (NLP) before TSDLC were classified as Group 1 and the other 99 eyes of 99 patients who had NLP vision were classified as Group 2. The outcomes of TSDLC including change in BCVA following surgery were analyzed for all patients and 49 subjects. RESULTS: The mean follow-up period in Group 1 was 19.1 +/- 13.5 months and 16.7 +/- 12.7 months in Group 2. The intraocular pressure (IOP) and the number of IOP lowering medications decreased in both groups (both p < 0.001). In all subjects, there was no significant difference between BCVA before surgery and at the last follow-up (2.4 +/- 0.9 log MAR and 2.5 +/- 0.8 log MAR, respectively, p = 0.612). However, in Group 1, BCVA was decreased from 1.4 +/- 1.0 to 1.9 +/- 1.1 log MAR after the TSDLC (p < 0.001). In those patients, visual loss > or = 0.2 log MAR was found in 31 eyes (63.3%) and light perception was lost in 15 eyes (30.6%). After treatment, corneal edema developed in 5 eyes (3.4%), phthisis bulbi and chronic hypotony occurred in 3 eyes each (2%) and iridocydlitis occurred in 2 eyes (1.4%). CONCLUSIONS: TSDLC in patients with refractory glaucoma showed an efficient reduction in IOP and the number of IOP-lowering medications. However, there was a significant loss in BCVA in many patients and therefore, careful monitoring regarding potential visual loss is necessary when considering TSDLC in glaucoma patients with useful vision.

PURPOSE: This paper aims to introduce the design of multiple mini-interviews (MMIs) as a tool to assess medical school applicants' attributes in alignment with the school's educational goals and to evaluate its utility. METHODS: In this MMI, candidates rotated through six stations (10 minutes per station), in which specific interview topics were drawn by mapping the school's educational goals with the core competencies for entering medical students. We conducted post-MMI surveys of all of the interviewers and candidates to investigate their experiences of MMIs. The G-coefficient and interclass correlation were analyzed to investigate the reliability of this test. Additionally, the candidates' MMI scores were compared across different backgrounds and a univariate analysis was used to estimate correlations between their MMI scores and prior academic achievements. RESULTS: A total of 164 candidates (a 98.8% response rate) and 19 interviewers (a 100% response rate) completed the surveys in the years 2014 and 2015. Both candidates and assessors showed positive responses to MMIs. The G-coefficient of MMI scores was 0.88 and the interclass correlation coefficients ranged from 0.58 to 0.75. The participants' total MMI scores did not differ across genders or undergraduate backgrounds and were not associated with age, undergraduate graduate point averages, nor the Korean medical school admission test (Medical Education Eligibility Test) scores. CONCLUSION: Our study illustrates the utility of MMIs that utilize the institution's educational goals to identify attributes to be pursued in the admission interviews in alignment with the institution's core values. Future research is warranted of the predictive validity of this MMI.

Cellular schwannoma is a variant of schwannoma, and is diagnosed as malignant tumor in over one fourth of cases because of its cellularity, mitotic activity and the occasional presence of bone destruction. This tumor is a tumor with low malignant potential and usually occurs in peripheral nervous system, mainly in the posterior mediastinum and retroperitoneal space. But pelvic retroperitoneal cellular schwannoma is very rare. Recently, we experienced a case of pelvic retroperitoneal cellular schwannoma in a 42-year-old woman; in reporting the case a brief review of the literature is included.

Background: A clinician reported unusually high incidence of A. xylosoxidans isolation from aspirated tissues in outpatient clinic. Methods: A. xylosoxidans isolates from January 2002 to June 2002 were investigated. The infection control nurse reviewed medical records and observed the procedures of tissue aspiration and culture at the clinical microbiology laboratory. Specimens were obtained for investigational cultures from dye, aspiration gun, slide alcohol sponge, tray, sink. water of sink, buffer solution, microscope, computer, and telephone. Results: A. xyloxosidans was isolated from twenty-four patients during 6 months. None of 24 cases had any typical signs or symptoms of infections by A. xylosoxidans. Observation of tissue aspiration and culture procedure revealed that buffer solution was used for prevention of specimen drying after tissue aspiration. Culture of the buffer solution yielded a heavy growth of A. xylosoxidans from four out of ten specimens. A. xylosoxidans was not isolated from any other investigational specimens. Conclusions: This was supposed to represent pseudoepidemic. Contaminated buffer solution was documented as the cause of this pseudoepidemic. The usage of buffer solution was stopped. During the follow-up period of 2 months, no additional A. Xylosoxidans was cultured from aspirated tissues.

This study was understand in order to examine the effect of hardness on stress-causing factors, defined in this study as burnout in nursing. The subjects were 248 nurses working in three general hospitals in Taejon. The instruments used for this study were a survey of general characteristics, modified Health-Related Hardiness Scale(HRHS) (25 items), job stress scale (63 items), and burnout scale(20 items). Analysis of data was done through the mean, percentage, Person correlation coefficient, and stepwise multiple regression done with a SAS program. The results of this study are as follows. 1) The average item score for the job stress was high at 4.44. In the subcategories, the highest degree of stress was night duty(5.11), and work overload(4.70), responsibility for extra affairs(4.70), conflict in nurse-doctor relationships(4.69), and low reward (4.63) in that order. 2) In the stepwise multiple regression analysis, hardiness(11.55%) was a significant determinant of burnout along with job stress(17.24%) and job duration(12.94%). The results of this study show that hardiness has an effect on psychological distress caused by stress.

BACKGROUND: The purpose of this study was to survey the nasal colonization of methicillin-resistant Staphylococcus aureus (MRSA) among the patients admitted in a medical intensive care unit (MICU) and analyze risk factors associated with the colonization. METHODS: The study was carried out on patients admitted into the MICU in a 1,250-bed tertiary care university hospital from January through December 2006. Nasal surveillance cultures were obtained from patients within 24 hours of admission to the unit. Data were analyzed retrospectively by the review of medical records. RESULTS: A total of 312 patients were screened with active nasal cultures; 36 patients (11.6%) were positive for MRSA. Of these, 22 (7.1%) were positive in the nasal cultures only and 14 (4.5%) were positive in the cultures of other specimens (13, sputum; 1, joint fluid) in addition to the nasal swabs. Among the risk factors for MRSA nasal colonization were sex (man), route of admission (from other ICUs or wards), a history of ICU admission during the recent 12 months, and prolonged hospital days in ICU. CONCLUSION: MRSA nasal carrier rate was found higher in this study than in those reported in the literature. Most of the patients colonized with MRSA in the nostril were not colonized with the organism elsewhere in the body. Whether or not active surveillance for MRSA should be performed would depend on the nasal colonization rate of the patients at the time of admission to the ICU.
