The study was conducted to confirm the construct of individual perception and preference for work characteristics as personal factors influencing Korean nurses' job satisfaction. The subjects of the study were 231 nurses who are currently working in intensive care units and have been for a minimum of 6 months. The study used the Staff Perception and Preference Scale(Song et al., 1997) to measure the individual's perception and preference on the technical, practice, and management components of the ideal work environment. The Korean version of the Staff Perception and Preference Scale consists of 16 items on perception and 13 on preference with each item related on a scale from 1 (not at all) to 4 (a great deal). Psychometric testing revealed that the preference and perception scale is internally consistent with Chronbach's alphas of .83 for perception scale and .80 for preference scale. The subscales of the perception and preference scale also showed acceptable reliability for the early stage of the development of the instruments with Chronbach alphas of .62-.76 and .69-.83 respectively. Criterion0related validity of the scale was tested by examining correlations with individual growth need that is conceptually close to individual preference, but not to individual perception. Individual growth need was significantly related to individual preference(r=.63, p<.05), but the correlation with the perception scale was not significant. A separate factor analysis for the each of perception and preference scales was performed with a three-factor loading solution based on a previous study. The results on the staff perception scale confirmed with varimax rotation that the items were cleanly and strongly loaded on technique, practice and management components, which together explained 50.7% of the variance. The factor analysis on the staff preference scale also yielded a three factor solution that explained 56.7% of the variance, but items on technique and management components were loaded together. This phenomena may due to the current nursing delivery system in Korea where nurses never experience either shared governance nor case management, and as a results they may not be able to consider management roles as their potential extended roles. Therefore, more efforts should be given to enhance nurses' autonomy and decision making in the technique, practice and management components of their work environment. Meanwhile, there is a need for continuously confirming and developing tools for individual perception and preferences to effectively enhance job satisfaction among Korea nurses through innovative work environments.

The purposes of this study were to determine the factors that influence job satisfaction for ICU nurses and to analyze group differences in job satisfaction based on the nurses' preference and perception of the work environment with an enhanced professional role. A total of 231 nurses who had been working in Intensive Care Units at least for 6 months at selected university hospitals participated in the study while head nurses or those with administrative positions were excluded. The study participants had an average of 33 months of clinical experience with an age range of 23 to 40 years. The data were analyzed by utilizing SPSSWIN and the results are as follows. 1) Hierarchical multiple regression analysis showed that work characteristics defined by Job characteristics theory and nurses' preference/ perception of ideal work environment together explained 33% of variance in job satisfaction. Skill variety, task identity and autonomy as well as individual perception of work environment were significant variables for explaining job satisfaction. Job satisfaction was not significantly related to age, marital status, education, and clinical experience. 2) The groups classified by nurses' preference and perception of work environment were significantly different in their job satisfaction. Nurses with high preference and high perception showed significantly higher general and specific job satisfaction than other nurses. The nurses who showed high preference but perceived their work environment as not reflecting ideal job characteristics reported the lowest job satisfaction among the groups. In conclusion, the role of individual preference and perception of the work environment in explaining the relationship between the redesign of work environment and job satisfaction was supported by the study. The preferences of nurses to the innovative work characteristics should be considered in the process of enhancing job characteristics to lead job satisfaction and low turn over and ultimately to improve quality of care.

PURPOSE: The purpose of this study was to analyze the characteristic MR findings of childhood metachromatic leukodystrophy. MATERIALS AND METHODS: Five female patients (10--29 months old;mean age, 21.8 months) of biochemically confirmed metachromatic leukodystrophy were included in this study. We evaluated the extent of white matter degeneration, which was shown as high signal intensity on T2-weighted image, and the presence or absence of the enhancement. Result.' All 5 cases showed high signal intensity in periventricular deep white matter and centrum semiovale which were bilateral, symmetric and confluent. Posterior predominace, sparing of subcortical U fibers and immediate periventricular white matter, and the involvement of splenium of corpus callosum were also noted in all cases. There were other manifestations, such as 'tigroid pattern' in centrum semiovale (n=4), the involvement of genu of corpus callosum(n=4), posterior limb of internal capsule(n=4), descending pyramidal tracts (n=3), deep cerebellar white matter(n=1), claustrum(n=2), and diffuse brain atrophy(n=1). In three cases with Gd-infusion, contrast enhancement of the lesion was not seen. CONCLUSION: In childhood metachromatic leukodystrophy, MRI can clearly demonstrate the chracteristic extent of the white matter lesion and other associated findings, facilitating the differential diagnosis from other similar leukodystrophies.

Hajdu-Cheney syndrome (HCS) is a rare skeletal dysplasia that is characterized by acroosteolysis of the distal phalanges, distinctive craniofacial and skull changes, dental abnormalities and generalized osteoporosis. The clinical and radiologic characteristics are variable and these characteristics progress with age. This syndrome shows autosomal dominant inheritance with sporadic cases. The genetic defects or molecular pathogenesis of HCS are still unknown. We experienced a case of Hajdu-Cheney syndrome in a 20-year-old man who had generalized osteoporosis with multiple non-traumatic spine compression fractures. He had acroosteolysis of the hands and feet, wormian bones in the skull, facial dysmorphism (mid-facial flattening, micrognathia and bushy eyebrows), a high arched palate, malocclusion and short dental alveolar processes. HCS was diagnosed based on the clinical and radiologic evidence. For the differential diagnosis, we excluded the other possible causes of the acroosteolysis and wormian bones, including hyperparathyroidism, osteogenesis imperfecta, hypophosphatemia and mandibuloacral dysplasia. The specific treatment of HCS is unknown, but case reports with bisphosphonate treatment have been reported.

BACKGROUND AND OBJECTIVE: IgG subclass deficiency has been reported in patients with bronchial asthma and is associated with recurrent respiratory tract infections. This study was done to identify prevalence of IgG subclass deficiency and to evaluate the possible difference between atopic and non-atopic asthmatics. Subjects and METHODS: We measured serum levels of IgG and IgG subclass in 35 asthmatic patients and 50 healthy controls using nephelometry. Reference values of each IgG subclass was defined as cumulative percentile between 2.5% to 97.5% of controls. RESULTS: Total IgG, IgG1 and IgG2 of asthmatics were significantly lower than for those of controls(p<0.05, respectively). In atopic asthmatics, compared with non-atopic asthmatics, IgG4 level was significantly higher (p<0.05). The frequency of IgG subclass levels below the reference value was eight (22.9%) of 35 asthmatics. CONCLUSION: IgG, IgG1 and IgG2 were significantly lower in asthmatic patients. Some patients had IgG subclass levels below reference value. Further studies will be needed to evaluate their clinical significance.

PURPOSE: To evaluate the efficacy of computed tomography(CT) in detecting pericardial adhesion. MATERIALS AND METHODS: CT of 32 patients with 'redo-valve surgery' was retrospectively evaluated for the location and appearance of their surgically confirmed pericardial adhesion. CT of 20 cases without cardiac or pericardial disease was reviewed as normal control. RESULTS: Nodular increased density at the site of adhesion between the sternum and the right atrium(RA) or ascending aorta(n=10), retrosternal dirty fat(n=10), obliteration of the pericardial fat(n=28), cardiac contour change with or without nodular epicardial fat accumulation(n=10), diffuse pericardial thickening(n=14), and pericardial calcification(n=13) were considered to be important findings. We also noticed an additional findings of beak-like projection of RA appendage(n=13), but was considered less significant because they were also observed in 4 normal subjects. CONCLUSION: CT scan is an effective, simple, and noninvasive method for predicting pericardial adhesion that may be occurred after redo-valve surgery.

Truncus arteriosus is characterized by a single arterial vessel arising from the base of the heart and giving origin to the systemic, pulmonary and coronary circulation. To evaluate the incidence, types, and associated anomalies, 18cases of truncus arteriosus diagnosed by angiocardiography, were reviewed and were compared with other reports. Ten of them were confirmed by operation. The overall incidence of truncus arteriosus was 0.127%. Accordin to Collett and Edwards classification. Type I was encountered in 11cases(61%), type II in 4cases(22%), and type III in 3cases(17%), All the patients had subtruncal ventricular septal defects. Eight patients showed truncal valve regurgitation and valve stenosis was noted in one case. A right aortic arch was present in 9 cases. Associated anomalies were atrial septal defect(8cases), patent ductus arteriosus(3cases), coarctation of the aorta(2cases), isolation of the left subclavian artery(2 cases), and right aortic arch with an aberrant left subclavian artery(1case). Truncus arteriosus is an uncommon congenital cardio vascular malformation. In the group of cases which we encountered, type I was the most common anomaly. Frequently associated anomalies were right aortic arch, incompetent truncal valve and atrial septal defect.

Sjogren's syndrome (SS) is an autoimmune disease characterized by a lymphocytic infiltration of the salivary and lacrimal glands leading to a progressive destruction of these glands due to the production of autoantibodies. This disorder is either isolated (primary SS) or associated with other systemic diseases (secondary SS). The occurrence of B-cell non-Hodgkin's lymphoma (NHL) represents the major complication in the evolution of SS patients. The risk of developing NHL, which is equivalent for both primary and secondary SS, was estimated to be 44 times greater than that observed in a comparable normal population. NHLs in SS patients occur preferentially in the salivary glands and in other mucosa-associated lymphoid tissues (MALT). However, it can also occur in the lymph nodes or bone marrow. We documented a case of low-grade B-cell lymphoma of MALT in the right eyelid and primary biliary cirrhosis (PBC) of a patient with SS. To the best of our knowledge, this is the first case reported in Korea.

PURPOSE: The purpose of this study was to analyze patient factors including smoking, body mass index, correction angle, graft material, presence of lateral cortex fracture, and age for the effect on bone union after open-wedge high tibial osteotomy and the effect of graft material used for lateral cortex fractures. MATERIALS AND METHODS: This retrospective study was conducted on 54 patients and 58 cases with osteoarthritic change Kallgren-Lawrence grade 2 or less from May 2012 to June 2014. Average follow-up period was 22 months (14–38 months). The patients were divided into two groups according to patient related factors and graft materials (allograft, n=6; beta-tricalcium phosphate [β-TCP], n=6) used for lateral cortex fractures and were analyzed for the relationship with bone union after open-wedge high tibial osteotomy. Radiographic and clinic analyses were performed, and van Hemert grading was used for grading bone union at 6 weeks, 3 months, 6 months, and 1 year postoperatively. RESULTS: The non-smoking group and the group without lateral cortex fracture showed significantly higher bone union rates than the control group. No significant clinical or radiological difference was observed between the two groups in 12 cases and the allograft group showed significantly higher rates of union at 6 months and 1 year postoperatively according to the van Hemert grading. CONCLUSION: Smoking and the presence of a lateral cortex fracture is a risk factor for nonunion in medial open-wedge high tibial osteotomy. The use of allograft material rather than β-TCP for lateral cortex fractures is thought to result in better bone union.
