PURPOSE: This study was to compare job stress and job satisfaction between ward nurses and outpatient nurses, and to identify the correlation between job stress and job satisfaction. METHODS: The subjects of this study were 200 ward nurses and 85 outpatient nurses in G and I University Hospital in Incheon. The data were collected in March 2010 and analyzed with t-test and Pearson correlation coefficient. RESULTS: There was no significant difference in overall job stress between two groups, but slightly higher stress level for ward nurses. In sub-area of job stress, 'nursing duty' was primary for both groups. And in 'nursing duty' (t=2.05, p=.041), 'conflict with patients' (t=2.73, p=.007), and 'working environment' (t=3.37, p<.001) ward nurses showed significant higher level of stress than outpatient nurses. For job satisfaction, outpatient nurses showed higher level significantly (t=-2.98, p=.003). And both groups of nurses' job satisfaction was negatively correlated with job stress significantly (r=-.31, p<.001). CONCLUSION: It will be possible to reduce job stress and promote job satisfaction level for both groups of nurses by adding staffs, and specifically for ward nurses by improving facilities for relax and appropriate supply, and for outpatient nurses by managing interpersonal stress and reducing side tasks.

Dysregulation of TGF-beta that is a modulator of cell growth and differentiation can result in uncontrolled growth and tumor formation. Monitoring these pattern of genes and protein expression during tumor development will provide a basis for understanding normal growth and distortion of osteochondrogenesis. Our comparative studies on the experssion of TGF-beta protein indicate that TGF-beta may primarily be a regulator of epithelial differentiation during tooth development (between 4 weeks and 40 gestational weeks) and tumorigenesis of odontogenic neoplasm (ameloblastoma). In early human tooth germ (cap/early bell stage) TGF-beta protein was found in the epithelial dentallamina and enamel orgen. TGF-beta experessions were seen in inner and outer dental epithelium during bell stage. During enamel and cementum appositional stage, TGF-beta expression shifted from the ameloblast to the odontoblast. In eruption stage, TGF-beta expressions look like moderate positive pattern in odontoblast and rare pattern in enamel, dentin and cementum. TGF-beta expressions of follicular and plexiform amelobalstoma are moderate positive reaction in ectodermal tumor components and mild positive in vessels of stroma tissue. In acanthomatous type, TGF-beta expression was shown severely positive finding in stellate reticulum cell. TGF-beta expressions were noted moderate reaction in margin of tumor epithelium and stellate reticulum cell of granular ameloblastoma. In unicystic ameloblastoma, TGF-beta expression was rare feature in cystic luminal epithelium. With these result, I should be suggested that TGF-beta may play an important role in epithelial-mesenchymal interactions in human tooth morphogenesis and development of odontogenic epithelial tumors.

The lymphoepithelial cyst (LEC) rarely occurs in the thyroid gland. The LEC has been thought to be related to developmental rest, namely solid cell nest, which is derived from ultimobranchial body. We report a case of lymphoepithial cyst in a 34- year-old woman clinically diagnosed with Hashimoto's thyroiditis. The cyst was located in mid to lower portion of the left lobe. It was a single unilocular cyst, which for the most part was lined with squamous epithelium, and at certain foci with ciliated columnar epithelium. The cyst wall showed a dense lymphocytic infiltration, numerous lymphoid follicles with germinal centers and admixed thyroid follicles. This morphology is similar to the branchial cleft cyst, with the exception of the thyroid follicles in the cyst wall. Near the cyst were several solid epidermoid cell nests. Immunohistochemical stain of this cyst-lining epithelium and solid cell nests showed CEA positivity. In view of the similarity in histomorphology and CEA positivity to branchial cleft cyst of the lateral neck, the LEC of the thyroid could also have been of branchial origin. However, the admixed thyroid follicles in the cyst wall suggests that the LEC of the thyroid gland might have derived from another branchial cleft as a ultimobranchial body, because it has the potential for thyroid follicular differentiation.

Renal dysplasia results from aberrant histogenesis in metanephric differentiation. It is characterized morphologically by abnormal organization and a persistence of primitive structures, such as cartilage, undifferentiated mesenchyme, and immature tubules. Six cases of renal dysplasia from five children and one adult are reviewed. Five patients were female and one patient was male. The chief complaint was urinary incontinence in four patients, dysuria in one patient, and the sixth patient suffered from vesicoureteral reflux. No evidence of family history of renal dysplasia in any patient was seen. According to Risdon's classification, three cases were hypoplastic dysplasia, one case was dysplasia in a duplex system, one case was dysplasia in a triplex system, and one case was dysplasia with vesicoureteral reflux. The ipsilateral ectopic ureteral orifice was identified in four patients, two of which drained into a Gartner's duct cyst, and the orifice was suggested in one patient. On histologic examination, all cases showed primitive ducts surrounded by concentrically arranged primitive mesenchyme. Nests of metaplastic cartilage were observed within the stroma in three of the six cases.

One hundred and thirty-eight strains of Mycobacterium tuberculosis isolated from the 7th nationwide tuberculosis prevalence survey in 1995 were subjected to the restriction fragment length polymorphism (RFLP) analysis using IS6110 probe to define the representative fingerprinting patterns of Korean strains of M. tuberculosis and to evaluate the usefulness of DNA fingerprinting in tracing the transmission link of M. tuberculosis. Among 138 strains, 129 different IS6l10 RFLP types were identified. The number of bands in IS6110 RFLP types diversed from 1 to 20, and the majority (75%) was 9 to 14 bands. The RFLP patterns of 8 out of 15 strains isolated from the follow-up survey of one and half year later after the 7th national TB prevalence survey were unchanged when compared with previous RFLP patterns. Fifteen (11%) out of 138 strains were grouped in 6 IS6110 clusters; 2 with 10 copies, 2 with 12 copies, 1 with 14 copies, and 1 with 17 copies. These clusters were unable to be subclassified by IS1081 or (GTG) probes except one cluster by pTBN12 probe. The transmission links of 2 clusters were deducible; one from household and another from neighborhood, but those of remaining clusters were unclear because they had no contact one another. The results suggest that vigorous transmissions in tuberculosis are still progressing in Korea.
