Dedifferentiated chordoma is a rare pathologic entity presenting an additional sarcomatous component in otherwise classical chordoma. It has been also emphasized that this neoplasm is classified as a distinct entity because of its different clinical settings and aggressive behavior. Dedifferentiation is a peculiar phenomenon but its histogenesis has remained controversial. A 50-yera-old man developed a huge tumor mass in the retrorectal, presacral area, featured with two histological components. The one was a typical chordoma accounted for approximately 60% of the mass and the other was made up of highly cellular, plemorphic, undifferentiated tumor cells, reminiscent partly to the cells of plemorphic malignant fibrous histiocytoma. Ultrastructural features and immunoreactivity against cytokeratin, S-100 protein and alpha-1-antichymotrypsin in both portions support that histologically different components of this neoplasm derive from the same origin. To our knowledge, this is the first case of dedifferentiated chordoma in Korea.

Epithelioid hemangioendothelioma is a recently described vascular neoplasm characterized by epitheloiod endothelial linings and its borderline biologic behavior. We report a case of epithelioid hemangioendothelioma in a 6-year-old male. The tumor was presented as a non-tender dermal nodule on the left middle finger. The microscopic sections revealed irregular proliferation of vascular channels lined by epithelioid cells with histiocytoid features and frequent intracytoplasmic vacuoles, mimicking so called signet ring cells. Immunohistochemical stainings for factor VIII and vimentin were positive both in epithelioid and vacuolated endothelial cell. Electron microscopic finding reveals abundant intermediate filaments.

PURPOSE: The purpose of this study was to translate the Self-Reflection and Insight Scale (SRIS) into Korean and test its validity and reliability. METHODS: Participants were 340 nursing students who were recruited from 5 nursing colleges in Korea. Data were collected from November 21 to December 20, 2016 and analyzed using the IBM Statistics SPSS 22.0 and AMOS 23.0 programs. Exploratory factor analysis, Confirmatory factor analysis, and concurrent validity analysis were performed. RESULTS: For the Korean-SRIS (K-SRIS) 4 items were deleted from the original SRIS. The final scale consisted of 16 items which were sorted into- the 2 factors: self-reflection (11 items), insight (5 items). The cumulative percent of variance was 50.91%. The statistically significant correlation between K-SRIS scores and the Reflection in Learning Scale (RLS) support the concurrent validity of the K-SRIS. The reliability of the scale, Cronbach's α was .83. CONCLUSION: The finding indicate that the K-SRIS has validity and reliability. Therefore it can be used for measuring and developing reflection ability in nursing students.

The purpose of study was to develop and validate Korean Sleep Scale A which can be easily administrated by nurse for a wide range of adult subjects. Dimensions of adult concept were derived by literature review. Previously developed sleep scales were also analyzed in order to develop scales items. The Korean sleep scale A was structured as a 15 item, 4 point like type scale. The Scale was tested an 298 female and male adult subjects after pilottest and content validation. The results showed reliability by internal consistency of Cronbach's alpha=75 Construct validity was tested by factor analysis and known group technique. Factor analysis showed 4 factor-sleep pattern, sleep evaluation, sleep result, and cause of sleep disturbance. Theses four factors explained 55.9% of total variance. Correlations between factors ranged from .15-.32. There was correlation among Korean Sleep Scale A score, Verran and Snyder-Halpern(VSH) Sleep Scale scale, and sleep satisfaction scale score, r= .71(p=.00), r=.51(p=.03), respectively. These study results partially support reliability, construct validity, and criterion related validity of Korean Sleep Scale A. Further validation study is required with other subjects and other settings.

PURPOSE: This study was done to identify effects of a life-esteemed education applied logotherapy on life respect, meaning of life, and depression on older elementary school students. METHODS: A nonequivalent control group and non-synchronized design was conducted with a convenience sample of 142 students. The program named 'My Precious Life'. consisted of one session per week for five weeks. Students were assigned to the experimental group (n=70) or the control group (72). Data were analyzed using descriptive statistics, Chi-square, Fisher's exact test, t-test, and repeated measured ANOVA with the SPSS/PC 18.0 program. RESULTS: Meaning of life and life respect increased significantly and depression decreased significantly for participants in the experimental group. CONCLUSION: The results of the study indicate that life-esteemed education applied logotherapy is effective in improving meaning of life and life respect and in decreasing depression in elementary school students. It can also be used to prevent existential distress and to intervene as a motif for having hope in life.

In order to investigate pathogenic genes and genetic relationships of Y. pseudotuberculosis strains, We isolated 9 strains of Y. pseudotuberculosis from 380 spring water sites in Seoul from 2000 to 2003. All isolates were distributed to the northeast area in Seoul. The isloates were analyzed for chromosomal virulence gene (inv) and plasmid-borne genes (yadA and lcrF) using PCR to assume pathogenicity. As a result, all isolates were positive for the inv gene, but only five isolates (55.6%) were positive for the yadA and lcrF genes. RAPD and PCR-ribotyping were tested and all isolates were grouped with 90% similarity. RAPD revealed 4 clusters and PCR-ribotyping revealed 2 clusters. The result of this experiments confirmed the view that RAPD had better powerful discrimination than PCR-ribotyping and RAPD typing was effective to distinguish between various strains of Y. pseudotuberculosis from spring water.
