PURPOSE: The purpose of this research was to delineate the effects of organizational injustice on negative behaviors of employees with the mediating effects of trust. METHODS: A survey was conducted among 550 nurses in 11 departments of 3 hospitals located in the Pohang area. Data were analyzed using frequency, descriptive statistics. correlation coefficients, regression analysis. RESULTS: Procedural injustice (beta=-.48, p<.001) had the greatest negative effect on organizational trust, followed by interactional injustice(beta=-.15, p<.001) and distributive injustice(beta=-.14, p<.001). For supervisor trust, both procedural (beta=-.11, p=.006) and interactional (beta=-.63, p<.001) injustice had a negative effect. While supervisor trust (beta=-.28, p<.001) had greater negative effects on organizational negative behaviors of nurses compared to organizational trust (beta=-.21, p<.001), supervisor trust (beta=-.29, p<.001) had negative effects on personal negative behaviors but organizational trust had no significant effect on personal negative behaviors. CONCLUSION: To reduce the negative organizational behaviors of nurses, an organizational effort is needed to reduce procedural injustice by introducing fair organizational management and to reduce interactional injustice through formal or informal communication channels between supervisors and nurses.

Cerebral infarction is caused by decreased perfusion to the brain. In the evaluation of the infarction, CT has been widely used but MRI ans SPECT recently tend to increase in use. The purpose of this study is to compare the efficacy of MR imaging with that of 99mTc-hexamethylpropylene amine(HMPAO) single photon emission computed tomography(SPECT) in the patients with cerebral infarction in the points of (1) number of detected lesion, (2) size of the lesion, and (3) correlation with clinical neurologic deficits. Sixty-one patients with cerebral infarctions(acute: 23, subacute:30, chronic:8) were reviewed. In all patients, MRI and corresponding 99mTc-HMPAO SPECT examinations were performed within a reasonable time span. We analyzed the fiadings of (1) clinical neurologic examination, (2) MR and, (3) Tc-99m-HMPAO SPECT independently they were compared later on. The lesion of SPECT was larger than the seen on MRI in 9 of 23 acute cases, 13 of 30 subacute cases, and 3 of 8 chronic cases. The lesion on MRI was larger than that on SPECT in seven acute cases, six subacute, and only one case in chronic stage. In the remaining cases, the size of the lesion was similar to that on both SPECT and MRI. For the detection of lesion, MRI was superior to SPECT in 15 acute cases, 13 subacute cases, and four chronic cases, while SPECT was super or to MRI in four of 30 cases at subacute stage, and one of 8 cases at chronic stage. In conclusion, there was a tendency that the detection rate of the lesion was higher on MRI but the lesion was larger on SPECT. The lesions detected on both MRI and SPECT correlated well with clinical symptoms.

It is a well known fact that the major craniofacial operation is a complicated procedure. In this procedure, the operative period is extremely long and blood loss is large, extremely difficult to estimate and continuous into the early postoperative period. The air was should be protected intraoperatively and postoperatively due to frequent airway obstruction. We had experienced of an anesthetic management for correction of hypertelorism. Anesthetic management of this case should focus on reduction intracranial pressure and volume. WE had performed neurolept anesthesia with controlled hyperventilation. The careful monitoring and frequent measuring of blood gas analysis, hematocrit, hourly urine output, electrolytes, body temperature, CVP, ECG, and acid-base balance status are recommended. We report a case of anesthetic management for a patient.

PURPOSE: To predict pulmonary arterial hypertension by comparing the extent of honeycombing lesion with the diameter of main pulmonary artery (MPA). MATERIALS AND METHODS: We retrospectively reviewed 21 patients (20 men, one woman) who showed honeycombing lesion on HRCT, and also analysized a control group of 30 (29men, one woman) who had no cardiopulmonary symptom and no abnormality on chest CT. On Chest HRCT, we scanned at four levels [1)aortic arch, 2) bifurcation of bronchus, 3) mid-portion of left ventricle, 4) dome of right diaphragm], and two radiologists then evaluated the proportion of honeycombing lesion within the entire lung field. According to the extent of this, we divided the patients into five groups [<20% (I), 20-39% (II), 40-59% (III), 60-79% (IV), > or = 80% (V)], and then divided Group I into two subgroups [<10 % (I|1), 10-19% (I-2)]. Using contrast-enhanced routine CT, the main pulmonary artery (MPA) was measured at its the widest diameter perpendicular to the long axisat the level of its bifurcation. RESULT: In group I (n=11) MPA was 28.4+/-2.6mm ; in group II (n=6), it was31.7+/-2.0mm ; in group III (n=2), 33.5mm ; in group IV (n=1), 33mm ; and in group V (n = 1), 39mm. In subgroup I-1MPA was 26.1+/-1.9mm, and in subgroup I-2, it was 29.8+/-1.6mm. In the control group, MPA was 25.1+/- 2.0mm. CONCLUSION: The extent of honeycombing lesion is closely related to the change in diameter of the MPA. Honeycombing lesion extending over more than 10% of the lung field may lead to pulmonary arterial hypertension.

We report here a case of pulmonary benign metastasizing leiomyoma from the uterus in a 45 year old woman. The patient presented for investigation of multiple pulmonary nodules on a routine chest roentgenogram. The patient had undergone uterine myomectomy due to uterine leiomyoma 10 years earlier. We performed thoracoscopic wedge resection for definitive diagnosis. Histologically, spindle shaped smooth muscle cells appeared between collagen stroma, histology similar to that seen in uterine myoma. The tumor tissue tested positive for estrogen and progesterone receptors. The pathological findings were consistent with benign metastasizing leiomyoma. The patient was in pre-menopause. She received no specific treatment for lung tumors, and we did not found any changes in the lesions after one year follow up without any medication.

PURPOSE: We intended to evaluate myocardial oxygen consumption (MVO2) by applying recirculation correction and modified one-compartment model to have a reference range of MVO2 in normal young population and to reveal the effect of recirculation on time-activity curve (TAC). Materials and METHODS: In nine normal male volunteers with mean age of 26.3+/-4.0, MVO2 was estimated with 925 MBq (25mCi) of 11C-Acetate (Neuroscience Research Institute, Gachon University of Medicine and Science, Incheon, Korea) and PET/CT (Biograph 6, Siemens Medical Solution, Germany). Analysis software such as MATLAB(R) v7.1 (Mathworks, Inc., United States), Excel(R) 2007 (Microsoft, United States), and SPSS(R) v12.0 (Apache Software Foundation, United States) were used. Twenty three frames were of 12 x 10, 5 x 60, 3 x 120, 2 x 300's duration, respectively. The modified one-compartmental model and the recirculation correction method were applied. Statistical analysis was performed by using Test of Normality, ANOVA and Post-Hoc (Scheffe's) analysis, and p-value less than 0.05 was considered as significant. RESULTS: The normal reference ranges of MVO2 were presented as 3.18-4.64 x 10(-4) ml/g/sec, 1.91-3.94 x 10(-4) ml/g/sec, 4.31-6.40 x 10(-4) ml/g/sec, 2.84-4.53 x 10(-4) ml/g/sec and 3.42-5.00 x 10(-4) ml/g/sec in the septum, the inferior wall, the lateral wall, the anterior wall and the entire wall, respectively. In addition, it was noted that the dual exponentiality of the clearance curve is due to the recirculation effect and that the characteristic of the curve is essentially mono-exponential. CONCLUSION: 11C-Acetate is a radiotracer worthwhile to assess MVO2. Re-circulated 11C can influence TAC of 11C in myocadia and so the recirculation correction must be considered when measuring MVO2.

We report a rare case of the concurrent manifestation of central diabetes insipidus (CDI) and type 2 diabetes mellitus (DM). A 56 year-old man was diagnosed as a type 2 DM on the basis of hyperglycemia with polyuria and polydipsia at a local clinic two months ago and started an oral hypoglycemic medication, but resulted in no symptomatic improvement at all. Upon admission to the university hospital, the patient's initial fasting blood sugar level was 140 mg/dL, and he showed polydipsic and polyuric conditions more than 8 L urine/day. Despite the hyperglycemia controlled with metformin and diet, his symptoms persisted. Further investigations including water deprivation test confirmed the coexisting CDI of unknown origin, and the patient's symptoms including an intense thirst were markedly improved by desmopressin nasal spray (10 microg/day). The possibility of a common origin of CDI and type 2 DM is raised in a review of the few relevant adult cases in the literature.

BACKGROUND: Quality of life (QoL) has emerged as an important issue to patients with chronic illness. Parkinson's disease (PD) is a chronic neurodegenerative disorder requiring life-time treatment and supportive care, which affects not only physical activity but also cognition, mood, and daily living. The author investigated the QoL of patients with PD and aimed to find factors that have an influence on the QoL. METHODS: One hundred thirty patients with PD were evaluated. The QoL was measured and assessed by the Parkinson's disease quality of life questionnaire (PDQL). The author analyzed demographic and social data and clinical profiles. The Beck Depression Inventory (BDI) and Spielburger's State-Trait Anxiety Inventory were used to evaluate depressive symptoms and anxiety levels. RESULTS: The mean age of onset of parkinsonian symptom was 55.2 +/-10.9 years and the average duration of treatment was 34.7 +/-36.9 months. Patients with high BDI score, low Schwab and England activities of daily living scale (SEADLS) score, high bradykinesia score, progressed Hoehn and Yahr stage, high Unified Parkinson's disease rating scale score, low educational period and high economic state were all correlated with low PDQL scores. Multivariate regression analysis showed that BDI score, bradykinesia score, SEADLS score, and educational period were significantly associated with PDQL score. CONCLUSIONS: In order of magnitude, BDI, bradykinesia, SEADLS and educational period were influenc-ing factors on PDQL. Therefore, to improve the QoL in patients with PD, we should consider not only physical disabili-ty, but also psychological factors, including depressive mood.
