PURPOSE: This is a descriptive correlation study to identify self-esteem, job satisfaction, and turnover intention among ship-building supply workers. METHODS: The subjects were 199 ship-building supply workers at two small & medium-sized ship-building supply companies in K city. The data were collected from March 1st through 31st, 2013. The collected data were analyzed using the SAS program through t-test, ANOVA, Scheffe test, and Pearson's correlation coefficients. RESULTS: There was a positive correlation between self-esteem and job satisfaction (r=.29, p<.001), a negative correlation between self-esteem and turnover intention (r=-.20, p<.001). Also there was a negative correlation between job satisfaction and turnover intention (r= -.58, p<.001). CONCLUSION: This finding identified that the self-esteem and job satisfaction were an important variable related to the turnover intention. Therefore, organizational managers need to develop strategies for improving workers' self-esteem and job satisfaction to prevent and decrease worker's turnover intention.

This study was carried out to observe the ultrastructure of tongue mast cells in frog, Bombina orientalis. In the light microscopy, mast cells were round, oval, spindle-like and irregular shape and occasionally had one or more tail-like long cytoplasmic processes. Mast cells had many red granules stained with toluidine blue in the cytoplasm. In the electron microscopy, mast cells had membrane-bounded granules and poorly developed organelles. The granules were composed of two parts, low and dense electron density. In high magnification the dense part in the middle region of granule had honey comb-like crystalline structure.

PURPOSE: This study was to assess the prevalence of workplace bullying and the relationship workplace bullying to self-esteem and turnover intention among clinical nurses. METHODS: The subjects were 223 clinical nurses at 3 small and medium-sized hospitals in K and B cities. The data were collected from February 1st throughout 28th, 2013. The collected data were analyzed using the SAS program through the frequency, percentage, mean, and Pearson's correlation coefficients. RESULTS: The rate of self-reported bullying in the nursing workplace was 24.6% of respondents. There was a negative correlation between workplace bullying and self-esteem (r=-.39, p<.001). Also there was a positive correlation between workplace bullying and turnover intention (r=.14, p=.031). CONCLUSION: Prevalence of self-reported bullying is high among small and medium-sized hospitals and is clearly associated with lower levels of self-esteem and higher levels of turnover intention. Therefore, an organizational nursing management program as a monitoring regularly the psychosocial work environment and policies and procedures to prevent and manage workplace bullying is strongly recommended for the promotion of self-esteem and reducing the nurse's intention to leave the organization.

Radiation sensitivity data was generated for two human cancer cell lines(KB, RPMI 2650) and human primary gingival fibroblast was tested three times using a viable cell number counting with a hemocytometer, MTT(3-[4,5-dimethylthiazol 2-yl]-2,5-dipheny tetrazolium bromide) assay, and LDH(Lactate dehydrogenase) assay. Single irradiation of 2, 4, 6, 10, 15, 20 Gy were aplied to the tumor cell lines and the primary cultured gingical fibroblast. The two fractions of 4 Gy an d 10 Gy were seperated with a 4 hour time interval. The irradiation was done with 241.5 cGy/min dose rate using 137 Cs MK cell irradiator at room temperature. The obtained results were as followed: 1. There was significantly different viable cell numbers as the amount of radiation dose on the tested cells were cell number counted with a hemocytometer, In fractions, there were more viable cells remaining, 2. Phase-contrast microscopically, radiation-induced morphologic changes were pronounced on the tumor cells, however, a lmost no differences on the gingival fibroblast. 3. There was significantly different absorbance at 2 Gy on RPMI 2650, 4 Gy on KB and GF in MTT assay. In fractions, the absorbance was significantly higher on KB. 4. THe level of extracellular LDH activity in the experimental group was significantly higher in the 2-4 Gy than the co ntrol group. 5. The total level of extracellular and intracellular LDH activity was decreased as increased amounts of radiation dose was applied.

OBJECTIVES: There have been several studies documenting the changing level of the conus throughout infancy and childhood, but there is only a little detailed study that documents the range of conus positions in a living adult population, especially in Korean, without spinal deformity. METHODS: we made a sequential study of magnetic resonance images of the lumbar spine to determine the variation in position of the conus medullaris in 650 living korean adults population without spinal deformity who checked MRI to identify the cause of low back pain. The study population consisted of patients over the age of 16 years. A T1-weighted, midline, sagittal image was reviewed for identifying the postion of conus. This location was recorded in relation to the upper, middle, or lower third of the adjacent vertebral body or the adjacent intervertebral disc. RESULTS: The study group consisted of 305 men(47%) and 345 women(53%) with a mean age 45.9 years(range, 16-79 years). The conus existed commonly at the middle third of L1(131cases, 20.2%), at the L1-2 intervertebral space(129cases, 19.8%), and the lower third of L1(123cases, 18.9%). The mean position of conus was the lower third of L1(range, middle third of T12 to middle third of L3). Conclusions:The mean position of conus was at the lower third of L1(range, middle third of T12 to middle third of L3). This results was same as that of foreign study. Our results of living korean adult population could allow for safe clinical procedures such as lumbar puncture, spinal anesthesia, and help to explain the differences among observed neurologic injuries from fracture-dislocation at the thoracolumbar junction.

The glomus tumor is a distinct neoplasm composed of modified perivascular smooth-muscle cells identical to those described in the glomus body. Malignant glomus tumor, also referred to as glomangiosarcoma, is exceedingly rare. It has been subdivided into locally infiltrative glomus tumor, glomangiosarcoma arising in a benign glomus tumor, and glomangiosarcoma arising in de novo. A few cases of malignant glomus tumor arising in a benign glomus tumor have been reported. A 55-year-old man underwent resection of a solitary nodule in the right shoulder area. The tumor was biphasic with a typical benign glomus tumor at the periphery and the central sarcomatous area composed of oval to elongated pleomorphic cells with a single prominent nucleolus and occasional mitotic figures. Both tumor components showed intense staining for vimentin, smooth muscle actin, and muscle specific actin. Herein, we report a case of a malignant glomus tumor arising in a benign glomus tumor with an immunohistochemical study and a review of literatures.

We experienced 2 cases of vesicovaginal fistula and obtained good results in the Department of Urology, Seoul Adventist Hospital, Seoul, Korea. The causes of vesicovaginal fistula were corrosive agent and prolonged labor, the ages were 42 and 52 years old, the locations were in the trigonal area in both cases and the sizes were 3cm and 1.5cm respectively. Both cases were treated successfully with suprapubic transvesical approach.
