In order to develop a self-report scale measureing posttraumatic distress, the authors translated Horowitz's(1979) Impact of Event Scale(IES) in Korean and explored its reliability and validity. The IES, BDI, STAI-I, II and MMPI-PTSD were administered to 143 college students and 104 patients who had experienced auto vehicle accident. The internal consistency(item-total correlation, students: r=.52, patients: r=.58:Cronbach's alpha, students: alpha=.87, patients: alpha=.89) and test-retest reliability (r=.73) were psychometrically approvable. To examine the validity, patients who were classified PTSD and non-PTSD were compared with IES, BDI, STAI-I, II and MMPI-PTSD. There were significant group differences in IES, BDI, and MMPI-PTSD. The IES was significantly correlated with BDI, STAI-II, and MMPI-PTSD. It was more highly correlated with MMPI-PTSD than BDI or STAI. The results of factor analysis suggested a single factor. IES showed sufficient discriminant validities between PTSD and non-PTSD(74.4%). Finally, the usefulness of the scale, some limitations, and implications for future study were discussed.

PURPOSE: This study was conducted to identify the influencing factors of job stress, self-efficacy, and organizational culture to presenteeism in clinical nurses. METHODS: A descriptive correlation research design was used for the this study. The subjects were 245 nurses working at the hospital in S, A and C City, from August 1st to October 30th 2014. Data were analyzed using t-test, ANOVA, Scheffe's test, stepwise multiple regression by SPSS 21.0 program. RESULTS: Job impairment indicated a significant positive relationship to job stress (p=.009), health problem (p<.001), and indicated significant negative relationship to self-efficacy (p<.001), innovative-oriented (p<.001), affiliative-oriented (p=.002), task-oriented (p=.026) in organizational culture. Significant factors of influencing to presenteeism were self-efficacy (p<.001, beta=-.363), culture of task-oriented (p<.001, beta=-.248) in organizational culture, and health problem (p=.002, beta=.187). CONCLUSION: Self-efficacy was defined as a variable to influence on presenteeism, and developing of strategies and program to strengthen self-efficacy and task-oriented of organizational culture in nursing is helpful to reduce the presenteeism of clinical nurses.

PURPOSE: To identify current status of university health care program. METHODS: Data and information from homepages of 309 colleges or universities in South Korea were collected. The data was analyzed by frequencies, t-test, chi2 test with SPSS Ver. 18.0. RESULTS: 117(37.9%) universities had organization of health care. Whether university had health care program or not had shown significantly depended on number of students, types of school (university or college), region, and existence of medical and nursing course. Medical course was shown as a strong predictor for facilitating university health care program limitedly focusing on diseases treatment. Health promotion programs have been operated in 15 universities, vaccination programs in 10 universities, and health screening in 20 universities. CONCLUSION: It is strongly recommended to revise the School Health Law for constructing a comprehensive university health care program consolidating health counseling and physical training.

The objective of this study was to explore the psychosocial factors such as life events, coping styles and family relationships in middle-aged depressed women. This study was designed to compare how different variables relate to depression in two different test groups: a depressed patient group and a normal group. The Beck Depression Inventory(BDI), The Ways of Coping Checklist, Interpersonal Support Evaluation List(ISEL), Family Environment Scale were administered to 116 depressed patients and 113 normal persons between the ages of 35 and 64. The results were as follows 1) The highest stress was marital stress(n=42, 36.2%) in patient group and family stress(n=44, 38.9%) in normal group, respectively. 2) There were significant differences between patient group and normal group in BDI scores (t=15.94, p<.0001), lift events(t=4.73, p<.0001), active coping(t=6.29, p<.0001), social support(t=7.20, p<.0001), and family relationship(t=5.75, p<.0001) except for passive coping(t=0.93, p=.35). 3) In depressed patient group, BDI scores had a significantly positive correlation with the scores of the life event(r=.24, p<.01) and negative correlation with active coping(r= -.22, p<01), social support(r=-.35, p<.001) and family relationships(r=-.30, p<.001). 4) In depressed patient group, multiple regression analysis showed that social support(12.3%, beta=-.281, T=-3.162, P=.002), lift events(5.1%, beta=.279, T=3.195, F=.002), and active coping(3.5%, beta=-.204, T=-2.225, F=.028) had predictability on the BDI scores and the total predictability was 20.9%. 5) Stress experienced in family relationships were highest in life events and there was a lack of consistency(in the BDI scores ol the coping styles). Social support was the most important factor and there were no significant differences between the two groups in family relationships.

BACKGROUND: The aim of the study was to determine prevalence of potential heterogeneous vancomycin-resistant Staphylococcus aureus (h-VRSA) among methicillin-resistant S. aureus (MRSA) isolated in Korea by using Mu-3 agar and to determine the effect of in vitro vancomycin exposure on the resistance. METHODS: MRSAs isolated in 1980-1999 were screened for the presence of VISA or h-VRSA using Mu-3 agar. MIC of vancomycin was tested by NCCLS agar dilution and broth microdilution tests. Suspected h-VRSA were selected by vancomycin-containing media and change of resistance was determined by population analysis. A strain with Mu50 type growth was serially exposed to 8 pg/ml of vancomycin containing media and change of the vancomycin resistance was determined. RESULTS: Among the 455 MRSA isolates, 18 (3.9 %) grew on selective brain heart infusion agar (BHIA), and 354 (77,8%) on Mu-3 agar, 66 (14.5%) with Mu3 type growth and 78 (17.1%) with Mu50 type growth. MIC of vancomycin was 11 pg/ml for some of the isolates when inocula were approximately 10' CFU, but VISA was not present when tested by NCCLS broth microdilution test. Exposure of the isolates to van-cornycin raised the MIC. Serial exposure once to 8 pg/ml of vancomycin resulted in significant decrease of cells susceptible to 8-12 pg/ml of vancomycin. CONCLUSION: VISA was not present among the test isolates, but 34.2% were suspected to be potential h-VRSAs, suggesting possible emergence of VISA if vancomycin was administered prolonged period. It is considered that suitable screening media are vancomycin containing BHIA for VISA and Mu-3 agar for h-VRSA. The isolates showing Mu50 type growth on Mu-3 agar are not always VISA, but rather h-VRSA.

BACKGROUND AND OBJECTIVES: Qualitative oculomotor abnormalities have been reported in parkinsonian patients for many years, but conflicting results have been obtained. This study was performed to evaluate the correlation between the severity of the disease and the abnormalities of the ocular movements in idiopathic parkinson's disease. METHODS: We gave the vestibular function tests in patients with idiopathic parkinson's disease and normal controls. Eye movement recordings were made with automated electronystagmography and rotation test was performed. A total of 46 patients (mean age : 61.2+/-6.7) and 24 controls (mean age : 60.5+/-4.3) were studied. The severity of the disease was divided into two groups by modified Hoehn & Yahr staging ; H-Y stage 1 and 2 as a mild group and stage 3 and 4 as a severe group. RESULTS: Saccadic latency and accuracy, pursuitic gain and velocity, vestibulo-ocular reflex (VOR) suppression by vision were significantly altered in patients, whereas mean velocity of optokinetic nystagmus (OKN) and VOR gain in darkness were normal. Alteration of saccadic latency and accuracy, pursuitic gain and velocity, VOR suppression by vision were profound in the severe group compared with a mild group and controls, but the above parameters did not differ between a mild group and controls. In a hemiparkinson's group, saccadic latency and accuracy, pursuitic gain, OKN mean velocity and gain was not different between the both sides. CONCLUSION: The results indicate that severe Parkinson's disease damages nigrostriatal or other specific pathways which were involved in the regulation of the saccadic, pursuitic and pursuitic-mediated visual fixation system. In a hemiparkinson's group asymmetric damage of dopaminergic innervation which was involved in the regulation of ocular movements was not found.

PURPOSE: To assess the efficacy of ancillary CT findings other than the obstructive lesion per se for the differential diagnosis of extrahepatic biliary obstruction. MATERIALS AND METHODS:CT findings of 49 patients with extrahepatic bile duct obstruction(22 benign and 27 malignant lesions) were assessed with emphasis on the patterns of ductal dilatation, contrast enhancement, and diffuse thickening of the extrahepatic ductal wall. Degree of central and peripheral intrahepratic ductal dilatation was graded by comparing with the adjacent portal radicles and hepatic parenchymal thickeness. RESULTS: Diffuse circumferential thickening and contrast enhancement of the extrahepatic ductal wall were more frequent in benign cases, but only thickening was statistically significant(p < 0.01). Peripheral intrahepatic ducts were more severely dilated by malignant causes(p < 0.01). With the same degrees of extrahepatic and central ductal dilatations, peripheral intrahepatic ducts were more severely dilated in malignant than in benign cases. CONCLUSION: These results may help to interpret the CT findings of extrahepatic biliary obstruction, particularly when the cause of biliary obstruction is uncertain.

BACKGROUND/AIMS: Multiple myeloma (MM)–associated cardiac damage, particularly according to the type of monoclonal (M) protein has not been elucidated. We sought to investigate relationship between elevated serum M protein levels and echocardiographic indices of cardiac structure and function in patients with MM. METHODS: We evaluated a total of 184 consecutive MM patients who underwent echocardiography for bone marrow pre-transplant screening. Serum levels of intact immunoglobulin M protein and free light chain kappa/lambda (FLC-κ/-λ) were measured. RESULTS: One hundred thirty-nine patients were non-light chain MM (non-LCMM) and 45 patients belonged to LCMM. In patients with non-LCMM, significant correlations were found between serum M protein and left atrial volume index (LAVi; r = 0.720, p < 0.0001), E/e’ (r = 0.511, p < 0.0001), and systolic pulmonary arterial pressure (r = 0.485, p < 0.0001). In patients with LCMM, log-transformed FLC-λ (log-λ) was correlated with left ventricular ejection fraction (LVEF, r = –0.536, p = 0.010), left ventricular (LV) end-systolic dimension (r = 0.500, p = 0.018), and LV end-systolic volume (r = 0.444, p = 0.038). On multivariate analyses, hematocrit and serum M protein were independent predictors of LAVi in patients with non-LCMM. In patient with LCMM, FLC-λ isotype was only found to be an independent determinant of LVEF. CONCLUSIONS: An increase in serum M protein was associated with LV diastolic dysfunction, whereas an increase in serum FLC-λ concentration showed a negative correlation with the echocardiographic parameters of LV systolic function. These findings also suggest that serum M protein has different effects on LV function according to the type of paraproteins in patients with MM.

The purpose of this study was to investigate the inpatients' perception of therapeutic-diets and of explanation about those diets provided by hospitals and satisfaction on therapeutic-diets at hospitals in Busan. The subjects consisted of 155 inpatients at five hospitals, which all had over 400 beds. The research was performed through the interviewing process using questionnaires. Seventy five percent of patients had received an explanation for their therapeutic-diet and 57.4% of respondents were given a manual that explained the reason for the therapeutic-diet. The professionals who explained the therapeutic-diet was 61.7% dietitians and 25.6% doctors. 59.4% of the patients considered the dietitian to be suitable for explaining the diet and 25.6% patients believed the doctor to be suitable for explaining the diet. In terms of the patients' perception of the therapeutic-diet explanation, 74.5% of the patients understood very well, 78.9% of them perceived this explanation as very important, and 67.5% of them were satisfied. On a scale of 5.00 for therapeutic-diet satisfaction, the average scores were 2.95 for meal characteristics and 3.06 for service characteristics. The items that scored low in therapeutic-diet satisfaction were taste, seasoning and appearance of meals, provision of selective menu and consideration of personal preference. In terms of the perception of understanding the therapeutic-diet, patients who were provided a manual and an explanation gave high scores to 'taste', 'variety of diet', 'meeting opportunity with dietitians', and 'prompt dealing with meal complications'. There was a significant (p<0.05) positive correlation between satisfaction for the explanation of the therapeutic-diet and the degree of perceived benefits of the explanation to the nutrition-management and the satisfaction on the therapeutic-diet satisfaction. Therefore, the results of this study suggest that hospitals should increase support for explaining the therapeutic-diet by dietitians and develop menus based on the patients' preference and the taste of the meal.
