Purpose: This study investigates the level of nursing professionalism and factors that affect nurse perceptions. Method: This study is a descriptive study involving 443 nursing students from two universities. Data were collected in September 2012 via a structured self-report questionnaire and subsequently analyzed using descriptive statistics, t-tests, one-way ANOVA, Pearson correlation coefficients, and multiple regression. Results: The mean scores for nurse image, core elements of nursing professionalism and nursing professionalism were 3.65±.46, 4.17±.39 and 3.59±.45, respectively. Nursing Professionalism had a significant positive correlation with nurse image (r=.749, p<.001) and core elements of nursing professionalism (r=.365, p<.001). In multiple linear regression, factors that influenced nursing professionalism were: temperament as nurses, professionalism, vision of career, role performance of nurses image, and fundamental nursing practical experience. These variables explained about 58.8% of the total variance in nursing professionalism. Conclusion: For more positive nursing professionalism among students, more attention should be paid to enhancing the positive image of nurses. Doing so can serve as a fundamental resource for the development of appropriate strategies for nursing professionalism.

From late 1880s based on Chicago School Style, tall buildings have been planned and constructed in major cities by recognizing as one of the solutions to release required office spaces in limited and higher land value downtown area. Consequently, tall buildings have became a powerful expression of architecture in the modern civilization due to their huge mass and vertical spaces. This dramatic phenomenon has rapidly spread to all over the world which want to be modern city. Specially, the center of a typhoon is Asia zone as well as Korea, China and Dubai. Basically, the design of tall building needs a spacial approach to form, space, vertical movement, construction and etc comparing with low-rise buildings. Because tall buildings have a different characters for natural system such as strong wind and huge thermal effect. Hence, to achieve proper tall building facade with architectural aesthetics, the design should understand a physical phenomenon for a wind movement and a thermal appearance such as the gravity is a natural phenomenon. Therefor, the target of the study is to understand a physical phenomenon and application on tall building"s facade design. It is very important work to know how design are applied for tall building"s facade design by a wind and the sun. So, this study starts with a basic research of a general facade design topic with wind and the sun. And to get the technical data for relationship between wind force, thermal issue and glass performance which is one of the facade component part, this study will use a computer simulation method. It will give a chance to inform design methodology for tall building"s facade design before starting initial facade design. Also it will make a database to understand what facade design for wind and the sun.

Background: To determine if positive pressure pneumoperitoneum has adverse effects on autonomic nervous system function, we examined baroreflex sensitivity (BRS) during carbon dioxide pneumoperitoneum in patients undergoing laparoscopic surgery. Methods: Twenty adult patients scheduled for laparoscopic gynecologic surgery were selected for the study. After general anesthesia was induced with sevoflurane, continuous electrocardiography and blood pressure were monitored. Spontaneous BRS was achieved using sequence method immediately before, and 5 minutes after, pneumoperitoneum. Heart rate variability (HRV) was also determined. Results: After pneumoperitoneum, BRS decreased from 12.9 ± 1.8 ms/mmHg to 8.1 ± 1.1 ms/mmHg (P < 0.05), and the power of the high frequency band decreased from 237.8 ms2/Hz to 49.6 ms2/Hz (P < 0.05). Conclusions: Compared to recordings obtained before pneumoperitoneum, BRS was decreased during pneumoperitoneum. This may predispose patients undergoing laparoscopic surgery to hemodynamic instability in addition to pneumoperitoneum itself. (Korean J Anesthesiol 2008; 55: 662~5)

Background: Age-based formulae have been widely used to predict appropriate size of the endotracheal tube (ETT) in children. The objective of this study was to evaluate the effectiveness of formula (internal diameter (ID) (mm) = [age in years + 16]/4) in Korean children. Methods: Ninety children under 8 years who required intubation with the regular uncuffed ETT were included in the study. Appropriate sizes were to permit a gas leak at 10-25 cmH2O with positive pressure ventilation. Initial intubation was tried with predetermined size and ETT was adjusted to meet this guideline. Results: A range of three tubes around the predicted tube size covered 79 cases (88%), whereas one size predicted by the formula applied to only 29 cases (32%). The selection of ETT which is 0.5 mm larger than the predicted size could allow appropriate intubation in 41 (45.6%) patients. Conclusions: The age-based formula (ID (mm) = [age in years + 16]/4) could predict the appropriate tube size in less than one third our patients. Therefore, we recommend three sizes be available before endotracheal intubation. (Korean J Anesthesiol 2007; 52: 275~7)
