1.Meningioma with Multiple Recurrences and Malignant Transformation Differences in expression of MIB1, p53 and progesterone receptor.
Korean Journal of Pathology 1997;31(12):1314-1316
We describe herein a case of meningioma showing three recurrences and in the end malignant transformation. To compare the differences of MIB1, p53 and progesterone receptor expressions in benign, recurrent and malignant meningiomas of the same patient, we performed immunohistochemical stainings for those markers. MIB1 and p53 reactivities were increased in proportion to histologic aggressiveness. By contrast, the progesterone receptor expression was noted in benign meningioma but not in malignant meningioma.

Epidermoid cysts occur rarely on the palms and soles, where hair is not present. These cysts have long been assumed to arise from traumatic implantation of epidermal fragment, but the pathogenesis is still controversial. Recently, with microscopic findings, immunohistochemical features, and molecular studies, the epidermoid cysts of the sole may be induced by the human papillomavirus. We report two cases of epidermoid cysts of the sole with the discussion of the pathogenesis.

PURPOSE: This study was done to identify the level of adjustment to hospital life, hospitalization recognition and hospital-related fear by school-aged children, and investigate the influence of hospitalization recognition and hospital-related fear on the hospital life of these children. METHODS: Participants were 112 three to six grade students who were hospitalized from 3 to 7 days at one of two children's hospital. Date were collected from September 2015 to March 2016. Data were analyzed using frequency, percentage, mean, standard deviation, multiple regression. RESULTS: The mean score for adjustment to hospital life was 3.43±0.40 of 5, for hospitalization recognition, 2.98±0.46 of 4 and for hospital-related fear, 1.37±0.28 of 3. Factors affecting adjustment to hospital life were hospital-related fear (β=-.28, p=.002) and hospitalization recognition (β=.27, p=.003). These factors explained 17% of the variance in adjustment to hospital life. CONCLUSION: Results indicate that adjustment to hospital life by school-aged children is not sufficient enough for them to cope with illnesses and hospitalization. Therefore, to improve adjustment to hospital life by school-aged children, nursing interventions that focus on increasing hospitalization recognition and decreasing hospital-related fear need to be developed.

OBJECTIVE: Immunofluorescence microscopy including confocal laser scanning microscopy and electron microscopy were used to study the production of fibronectin, tenascin, and laminin in the cumulus-corona (CC) cells surrounding mature, unfertilized oocytes after ovulation in view of their presumptive importance in the coordination of the processes leading to fertilization and early embryo cleavage, including the final maturation of the ovum, the sperm-egg interaction, and the complex biochemical mechanism between the ovum and the oviduct. METHODS: Mature oocyte-cumulus complex (OCC) was cultured for 24 and 48 hour and fixed in 3.7% formaldehyde. Specimens were incubated with a mixture of primary monoclonal antibodies recognizing different epitopes of fibronectin, tenascin, and laminin, and then with a mixture of secondary antibodies containing FITC, TRITC, and Cy-5 conjugated antibodies. Observation was made by confocal laser scanning microscope equipped with epifluorescece optics. Transmission electron microscopy were used to observe the OCC at 24 and 48 hours after cultrue. RESULTS: The immunocytochemical date demonstrated that CC masses are capable of producing fibronectin and tenascin but their production is heterogeneous in the CC population. Immunoreactivity to fibronectin and tenascin was shown mostly by inner corona cells, and the intensity of immunofluorescence decreased from the central corona cells to the peripheral cumulus cells. Colocalization of fibronectin and tenascin was evident in most CC cells. Moreover, fibronectin and tenascin immunoreactive material was observed in the intracytoplasmic areas, at the plasma membrane level as well as in the extracellular matrix. Whereas, laminin immunofluorescence was found around plasma membrane and extracellular area, but a intracytoplasmic reaction was rarely observed. The distribution of laminin immunofluorescence was similar to that of fibronectin and tenascin, but in some cumulus cells, colocalization between them was not found. Ultrastructurally, cumulus cells projected numerous long, thin microvilli into the intercellular area and some micovilli penetrated into zona pellucida. The inner layer of the cumulus mass was loose arrangement of relatively uniform, small cells with widened intercellular spaces, whereas in the outer layer, cumulus cells are rather larger in size and compact arrangement by narrow, irregular spaces. A small and large linear gap junctions were easily found at cell contacts. The cytoplasm of most cells had abundant organelles typical of steroidogenesis: numerous mitochondrias, a well-developed smooth endoplasmic reticulum, electron dense lipid droplets, and bundles of microtubules and microfilaments. Rudimentary disrupted basal lamina along the cytoplasmic border was rarely seen in a few inner conora cells. CONCLUSION: Even though the functional role of these extracellular matrix proteins remains still unclear, it is reasonable to suggest that they are necessary in various steps of the reproductive process. Cumulus cells appears to be a heterogeneous and dynamic system for suitable microenviroment of fertilization. And functional differences between corona and cumulus cells during the oocyte denudation may be accounted for particular distribution of these adhesive proteins and steroidogenesis-related organelles.

8.Impact of Unit-level Nurse Practice Environment on Nurse Turnover Intention in the Small and Medium Sized Hospitals.
Journal of Korean Academy of Nursing Administration 2012;18(4):414-423
PURPOSE: The purpose of this study was to investigate the impact of the unit-level nurse practice environment on nurse turnover intention in the small and medium sized hospitals. METHODS: A cross-sectional study was conducted using a questionnaire survey with 308 nurses in 38 nursing units of 6 small and medium sized hospitals, having over 200 beds and under 300 beds and located in B metropolitan city. Data were collected from July 20 to August 10, 2011. Data were analyzed using hierarchical multiple regression. RESULTS: The mean turnover intention in nurses of small and medium sized hospitals was 3.52+/-0.53. Factors affecting turnover intention in the nurses included age, work unit, monthly income, number of night-duties, work hours per day and unit-level nurse practice environment. The unit-level nurse practice environment accounted for 15% of turnover intention when other variables were controlled. CONCLUSION: The results of the study indicate that nurse turnover intention is associated with the nurse practice environment at the unit level. Small and medium sized hospitals can improve nurse retention and lower turnover intention by changing the nurse practice environment of unit, such as creating better support services and nurse participation in hospital affairs.

Journal of Korean Academy of Nursing Administration 2014;20(3):292-301
PURPOSE: The purpose of this study was to identify factors that affect reality shock in new nurses. METHODS: Participants were 216 newly graduated nurses with less than 1 year experience in 5 university and 10 general hospitals in Busan, Ulsan and Gyeongnam, A self-report questionnaire was completed by the nurses between November 18 and December 25, 2013. Data were analyzed using t-test, ANOVA and hierarchial multiple regression analysis with the SPSS/WIN 21.0 Program. RESULTS: Average scores for work environment and environmental reality shock were 2.63+/-0.33 and 2.66+/-0.43 points respectively. Regression analysis showed that with the nurses' demographic and work characteristics controlled, work environment explained 4.2% of the reality shock. Factors significantly affecting reality shock included nurses' changing residence because of job (beta=.21, p=.001), whether they were able to work on the unit of their choice (beta=-.13, p=.031) and whether they had a choice in days off (beta=-.14, p=.038). CONCLUSION: When these factors are considered, reduction in nurses' reality shock requires improvement in work environment, placing new nurses in a department of their choice and allowing them a choice in off-duty days. These measures would also help achieve organizational goals and develop the new nurses as professional nurses.
