PURPOSE: The purpose of this study was to identify the relationships among nursing students' knowledge, attitudes to advance medical directives and ethics values. METHODS: The study was a cross-sectional and descriptive survey, carried out with 232 students from two schools of nursing, one located in B and C city. Student nurses' knowledge, attitudes for advance medical directives and ethics values were measured using structured self-report questionnaires. Data were analyzed using t-test or one-way ANOVA, and Pearson correlation coefficients. RESULTS: The scores for knowledge, attitudes for medical advance directives were 7.18 and 3.07, and for ethics values, 3.47. Nursing students' knowledge and attitude showed a significant difference depending on grade. Nursing students' ethics values showed significant differences depending on whether a study on ethics had been completed. A positive correlation was observed between nursing students' knowledge, attitudes for advance medical directives and ethics values. CONCLUSION: The results of this study indicate that basic data for the development of an effective education program on ethics is important in establishing a positive attitude toward advance medical directives and the appropriate ethical values in student nurses.

PURPOSE: This study was aimed to explore the work experience of nurses who transitioned from the patient nursing department to administrative departments.METHODS: The participants were 11 nurses who had worked in departments of human resources, education and training, medical insurance review, information technology, and quality improvement. Data were collected through in-depth individual interviews done between December 2017 and July 2018 and were analyzed in terms of Giorgi's phenomenological methodology. The research question was ‘What kind of experience did you have as you transition to a new role from a nurse to a hospital administrative nurse? What are the challenges in carrying out a new role? How do you overcome obstacles and adjust to being a hospital administrative nurse?’RESULTS: The main essence of the administrative nurses' work adjustment experience is represented by six components; 1) Beginning of a new challenge in conflict, 2) Running into barriers, 3) Struggling to take root, 4) Recognizing changes in the hospital, 5) Gradually adjusting to change, 6) Becoming a proficient hospital administrative nurse.CONCLUSION: Based on these findings, it is essential to create systems that enable administrative nurses to adjust to their work without confusion, and continuously develop programs to enhance their competence.

The ureteropelvic junction is one of the most common site of obstruction in the upper urinary tract, though the etiology is still unclear. In the present study, a quantitative histological analysis of the ureteropelvic junction(UPJ) obstruction was performed on 23 patient specimens(10 children, 13 adults) and 14 normal control specimens(6 children, 8 adults). Color image analysis system was employed to examine and compare collagen and smooth muscle components of the lamina muscularis layer. Tissue matrix ratio, that is collagen-to-smooth muscle ratio, was calculated using Bio Scan OPTIMAS Ver 4.02. Relative ratio of lamina propria and lamina muscularis to UPJ was calculated as percentage provided by "Img Pro" computer program. The results showed an increased tissue matrix ratio of 0.68+/-0.42 in the child patient group compared with the value of 0.30+/-0.10 in the child control group(p<0.05), also the increased tissue matrix ratio of 1.45+/-1.67 in the adult patient group compared to 0.48+/-0.25 in the adult control group(p<0.05). But relative ratio of the lamina propria and lamina muscularis to UPJ was not statistically significant for each group(p>0.05). Our findings emphasize a significant increase in the tissue matrix ration(collagen-to-smooth muscle ratio) of the UPJ obstruction.

To investigate the effect of tumor removal and administration of OK432 on the splenic natural killer (NK) cell activity in the subcutaneous tumor bearing rats, NK cell activity assay using a 4-hour 51Cr release assay and flow cytometric analysis for NK cell population were performed. The results were as follows: 1. Splenic NK cell activity and population in the subcutaneous tumor bearing rats decreased along with the growth of the tumor. 2. The rats with subcutaneous tumor removal showed decrease of splenic NK cell activity, but splenic NK cell population was not decreased. 3. In the rats with subcutaneous tumor removal and OK432 administration, splenic NK cell activity was significantly increased 1 week after administration of OK432 and then gradually returned to normal, whereas increase of NK cell population was not significant. In the present study, splenic NK cell activity was significantly decreased despite removal of subcutaneous tumor. But with the administration of OK432, splenic NK cell activity returned to normal. Considering the role of NK cells on the first line of defense against the metastatic implantation of circulating tumor emboli, we suggest that perioperative administration of immunopotentiator such as OK432 may improve the patient's outcome after surgery of human neoplasm.

Chondroblastoma is a rare primary bone tumor which originates from cartilage, and represents approximate 1% af all bone tumor. The chondroblastoma arises most frequently from the epiphysis of the long bones with the humerus being the commonest site. It afflicts usually the young under 25 years with greater incidence in male. As there is no cartilage cell on craniofacial bone which is mainly fromed by intramembranous ossification, the chondroblastoma on the craniofacial bone is extremely rare. But the chondroblastoma recurred frequently in craniofacial bone when the mass is excised incompletely or curretted and, as the tumor has the outstanding ability of local invasiveness, it destructs the adjacent bone. In addition, it is difficult to diagnose differentially from sarcoma or giant cell tumor histopathologically. Due to the entities described above, it is necessary to remove the entire tumor mass as complete as possible, to treat with radiation pre or postoperatively for preventing from recurrence, and to observe for a long time. The chondroblastoma on temporal bone is rare and is difficult to diagnose and treat successfully. So we'd like to present a case of chondroblastoma which was originated from temporal side of TMJ with literatural review.
