Orthopantomogram is commonly used to evaluate root parallelism. "Good parallelism" between roots is widely accepted as one of the guidelines of a successful orthodontic treatment. In case there was a large angle between crown axis and root axis, and if we valued only the position of crown in establishing occlusal relationship without considering of the situation of root, the problem of root arrangement between adjacent teeth would be occurred. The estimate of root parallelism in mesiodistal direction before and after orthodontic treatment must be emphasized. The intent of this study was to determine the clinical importance and correlation of the angle between crown axis and root axis. Orthopantomograms of 105 orthodontic patients being treated in Yonsei university were used in this study. Twenty-eight teeth in both maxilla and mandible were selected and analyzed quantitively to evaluate the angle between crown axis and root axis, and obtain the correlationship among the individual teeth. The results are as follows: 1. Among the teeth presenting normal distribution, the maxillary right canine showed the largest mean valuer 5.73+/-4.42degrees), which was composed of the crown-root angles, and the mandibular left lateral incisor showed the smallest mean valuer 0.60+/-3.76degrees). 2. The crown-root angles of the maxillary incisors and the first molars, and the mandibular central incisors and the first molars didn`t show normal distribution and the ranges of these angles were dispersed. 3. Significant differences were present between the crown axis and the root axis except for lower first premolars. (p<0.05) 4. No significant difference was present for the crown-root angle between right and left side. (p<0.05) 5. No significant difference was present for the crown-root angle between male and female except for lower left first premolar. (p<0.05) 6. In the upper right quadrant, significant correlations were present between crown-root angles of the central incisor and lateral incisor, lateral incisor and canine. In the upper left quadrant, significant correlations were present between crown-root angles of the central incisor and lateral incisor. In the lower right quadrant, significant correlations were present between crown-root angles of the central incisor and lateral incisor, first molar and second molar. In the lower left quadrant, significant correlations were present between crown-root angles of the central incisor and lateral incisor, lateral incisor and canine, first molar and second molar.

BACKGROUND: Urinary tract is the most common site of nosocomial infections, accounting for 35% of all nosocomial infections. About 80-90% of these urinary tract infections are associated with urethral catheter insertion. Recently, we experienced an outbreak of nosocomial UTI (urinary tract infection) caused by Candida spp. in the surgical ICU (SICU) and we investigated the cause of UTI outbreak. METHODS: We collected data from clinical records and observed the current methods of care of urethral catheters in the SlCU. During the outbreak, we investigated the current procedures and maintenance care of urethral catheter insertion and educated the staff on the correct methods of the catheter insertion and care. We performed surveillance cultures of unused new urine bags, RESULTS: Between May 2000 and June 2000, 17 Candida spp. strains were isolated from urines of 17 patients hospitalized in the SICU of National Health Insurance Corporation Ilsan Hospital. All infections were attributed to the care of urethral catheter insertion and contaminated bags. We identified that routine bladder irrigation and emptying urine to a common urinal have been done incorrectly during the outbreak period. Rodotorula spp. was isolated from 4 urine bags (50% contamination rate) out of 8 unused new urine bags by surveillance cultures. CONCLUSION: The causes of the UTI outbreak caused by Candida spp. was terminated by outbreak investigation and change of contaminated urine bag.

PURPOSE: In this study, differences and relationship between teaching style, personality, job stress, and job satisfaction among preceptors were examined. METHODS: The participants were 121 preceptors. Data were collected in November and December 2010 and analyzed using descriptive statistics, ANOVA, Scheffe's test, and Pearson correlation coefficients. RESULTS: The most frequent teaching style was judgement-initiative, and personality scores were highest for conscientiousness. Job stress was average (3.05+/-.59), and job satisfaction was below the mid-point level (2.76+/-.39). Job stress and job satisfaction were significantly different according to teaching style. Significant correlations were found between personality and job stress, and personality and job satisfaction. CONCLUSIONS: These findings indicate that changes in perceived teaching style, and personality may be necessary to decrease job stress, and to promote job satisfaction among preceptors. The results of this study should be considered in the development of effective preceptor training programs.

PURPOSE: This study was examined to identify the relationship among knowledge, attitude, and compliance with preventive behavior on influenza A (H1N1) by University students. METHODS: The sample consisted of 101 students. The data were collected from August to September 2009 and analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression. RESULTS: The mean scores of knowledge (11.89 +/- 1.39), attitude (30.16 +/- 2.87), and compliance with preventive behavior (22.35 +/- 3.51) on influenza A (H1N1) were above the average. The level of knowledge was not significantly different regardless of characteristics. Students' attitude differed according to gender (p<.001), and plan to seasonal influenza vaccination for this year (p=.007). Compliance with preventive behavior was significantly different according to experience of seasonal influenza vaccination during last year (p=.010), experience of obtained information about influenza A (H1N1) (p=.037). Significant correlations were found between knowledge and compliance with preventive behavior (p<.001), attitude and compliance with preventive behavior (p<.001). Knowledge and attitude was a predictor of compliance with preventive behavior (23.4%). CONCLUSION: These findings indicate that perceived knowledge and attitude may be necessary to improve compliance with preventive behavior on influenza A (H1N1) among university students. The results of the study can be utilized in educational programs about preventing the occurrence of influenza among university students.

PURPOSE: The purpose of this study was to ascertain current status of nurses' perception, nursing performance, job stress, and burnout in relation to the Joint Commission International (JCI) hospital accreditation and to verify the relationships among these variables. METHODS: This cross-sectional study was performed using questionnaires. Data were collected from 220 nurses who worked at one hospital from April 5 to May 4, 2013. RESULTS: The scores for perception, nursing performance, job stress and burnout in relation to the JCI hospital accreditation were(on a five-point Likert scale) 3.23, 4.01, 3.56 and 3.40 respectively. A positive correlation was observed between perception and nursing performance. Burnout was negatively correlated with perception and nursing performance, and positively correlated with job stress. CONCLUSION: These results indicate that developing positive perception and reduced burnout in relation to the JCI hospital accreditation can produce good nursing performance. These findings can be utilized to develop strategies for reducing job stress and burnout in relation to the JCI hospital accreditation.

BACKGROUND: The purpose of this study is to evaluate the evidence for the effectiveness of different isolation policies in reducing the incidence of methicillin-resistant Staphylococcus aureus (MRSA) infection in hospital in-patients. METHODS: We prospectively evaluated the effectiveness of an isolation policy on transmission of MRSA in the 745-beds hospital. First period, all patients with MRSA (March - July 2000) were not isolated Second period, strict isolation policies were performed (August 2000 - January 2002). All patients with MRSA were isolated in separated room, hand hygiene using alcohol handrub, gowning and g1oving, apply of MRSA notice sticker, criteria in isolation remove, separated disinfection and wastement. Third period, semi strict isolation policies were performed (February 2002 - August 2005). Some patients with MRSA were isolated in separated room and others were admitted in general ward for bed shortage. Only some practices were performed in hand washing and separated disinfection in general ward. RESULTS: The rates of MRSA nosocomial infection per patients during 1st, 2nd, and 3rd surveillance were reported 0.56, 0.23, and 0.42 (P<0.05). Patient-days rate of MRSA nosocomial infection during 1st, 2nd, and 3rd surveillance were reported 0.62, 0.27, and 0.38 (P<0.05). CONCLUSION: With many different isolation policies, it was possible to reduce nosocomial infection of MRSA. In this study, strict isolation policies (2nd period) were the most effective practices in reducing MRSA infection.

PURPOSE: The purpose of this study was to describe role conflict and job satisfaction of Neurosurgery Clinical Nurse Specialist(NCNS) and to identify associated factors. METHOD: The target populations was 77 NCNSs from 30 general hospitals. Data were collected with self-administered questionnaires and analyzed using t-test and ANOVA. RESULTS: The overall mean scores of role conflict and job satisfaction were 3.60(+/-0.54) and 3.04(+/-0.46) respectively. Significant variables affecting role conflict were the working period as NCNS, the number of colleague NCNSs in working hospital, and assignment of prescription rights. The significant variable affecting job satisfaction was assignment of prescription rights. There was no statistically significant correlation between job and role conflict. CONCLUSION: The variable effecting both role conflict and job satisfaction was the extent of prescription rights. In order to improve the quality of patient care and to protect Neurosurgery Nurse Clinical Specialist, the enactment of law on prescription practice is needed.
