The purpose of this study was to identify the levels and factors influencing perceived knowledge of evidence-based practice(K-EBP) among university librarians. The results were as follows. Variables with significant differences in K-EBP were age, education level, employed type, position, frequency of reading journal articles, and attendance of conference. Multiple regression analysis showed that the predicting factors influencing K-EBP were education level and frequency of reading journal articles. Also, It turned out to be weak in critically appraising and applying research evidence in practice, and in understanding research literature and conducting research among items of K-EBP. For developing university librarians' K-EBP, they need to improve overall research literacy. Library organization and library sectors need to support research activities of librarians. Finally, many different education programs are needed to develop librarians' research skill and to utilize for enlargement of evidence-based practice.

A polymer-based flexible neural probe was fabricated for monitoring of neural activities from a brain. To improve the insertion stiffness, a 5 ${\mu}m$ thick biocompatible Au layer was electroplated between the top and bottom polymer layers. The developed neural probe penetrated a gel whose elastic modulus is similar to that of a live brain tissue without any fracture, To minimize mechanical residual stress and bending from the probe, two new methods were employed: (1) use of a thermal annealing process after completing the device and (2) incorporation of multiple different layers to compensate the residual stress between top and bottom layers. Mechanical bending around the probe tip was clearly removed after employing the two processes. In electrical test, the developed probe showed a proper impedance value to record neural signals from a brain and the result remained the same for 72 hours. In simple in-vitro probe characterization, the probe showed a great removal of residual stress and an excellent recording performance. The in-vitro recording results did not change even after 1 week, suggesting that this electrode has the potential for great recording from neuron firing and long-term implant performance.

This study investigated the quality characteristics of breads made with addition of lotus(Nelumbo nucifera) seeds powder. Breads were prepared with 0, 5, 10, 15 and 20%(w/w) lotus seed powder instead of wheat flour. The moisture, crude protein, crude fat, crude ash and crude fiber contents of the breads increased as the proportion of lotus seed powder increased. The pH of the breads increased as lotus seed powder levels increased. The weight of breads increased with increasing lotus seed powder levels, whereas volume decreased. The specific volumes of breads with lotus seed powder were in the range of $3.59{\sim}4.68\;mL/g$, whereas the control value was 5.12 mL/g. The baking loss rates of breads prepared with 5%, 15% and 20% lotus seed powder were 8.95%, 8.17% and 7.67%, respectively. Lightness (L value) of breads was decreased by addition of lotus seed powder, whereas redness (a value) and yellowness (b value) increased in crumb and crust. Texture measurements showed that hardness and gumminess increased with increased lotus seed powder levels, but springiness decreased. In sensory evaluation, the highest scores for flavor, taste and overall preference were obtained when lotus seed powder content was 10%, and color and texture were the best when 5% of lotus seed powder was added. Thus, addition of $5{\sim}10%$ lotus seed powder may have a role in functional bread preparation, resulting in improved quality.

The potential importance of proteomic approaches has been clearly demonstrated in other fields of human medical research, including liver and heart disease and certain forms of cancer. However, reproductive researches have been applied to proteomics poorly. Proteomics can be defined as the systematic analysis of proteins for their identity, quantity, and function. It could increase the predictability of early drug development and identify non-invasive biomarkers of toxicity or efficacy. Proteome analysis is most commonly accomplished by the combination of two-dimensional gel electrophoresis(2DE) and MALDI-TOF(matrix-assisted laser desorption ionization-time of flight) MS(mass spectrometry) or protein chip array and SELDI-TOF(surface-enhanced laser desorption ionization-time of flight) MS. In addition understanding the possessing knowledge of the developing biomarkers used to assess reproductive biology will also be essential components relevant to the topic of reproduction. The continued integration of proteomic and genomic data will have a fundamental impact on our understanding of the normal functioning of cells and organisms and will give insights into complex cellular processes and disease and provides new opportunities for the development of diagnostics and therapeutics. The challenge to researchers in the field of reproduction is to harness this new technology as well as others that are available to a greater extent than at present as they have considerable potential to greatly improve our understanding of the molecular aspects of reproduction both in health and disease.

This study examined the relationship between the happiness, empowerment, and nursing performance of nurses with more than one-year of clinical experience, and the factors affecting the nursing performance. The subjects were 164 nurses who worked in two general hospitals in Incheon and Chungcheong-do, Korea. Data were collected from October to November 2018. The main findings of this study were as follows. The mean scores for happiness, empowerment, and nursing performance were 3.07±0.36, 3.37±0.43, and 3.40±0.44 points. Happiness was positively correlated with empowerment (r=.58, p<.01) and nursing performance (r=.58, p<.01), empowerment was positively correlated with the nursing performance (r=.58, p<.01). The factors influencing the nursing performance were empowerment (β=.65, p<.001), total length of a clinical career (β=.19, p<.001), education level (β=.12, p<.05), and happiness (β=.12, p=.05), showing an explanatory power of 64%. Based on these results, it is necessary to provide sufficient human and physical resources to improve the nursing performance and manage the organizational level to increase the nurses' happiness and empowerment. To improve the work performance of nurses, an empowerment improvement program tailored to the clinical experience and educational level should be developed, and the working environment that can increase the nurse's happiness should be improved.

This study was conducted to evaluate the moral distress, moral sensitivity, and the factors that influence moral distress and the experience of moral distress among nurse working in a long-term care hospital. Overall, 180 nurses working in long-term care hospital in G Province were evaluated. Date were collected from March 21 to April 8, 2016 and analyzed using the SPSS/WIN 23.0 program. The mean of moral distress among nurses was 3.57 and the moral sensitivity was 4.82, and these factors was significantly and positively correlated (r=0.494, p<0.001). Regression analysis revealed that the factors that significantly influenced moral distress were moral sensitivity and ethical dilemmas when conducting nursing practices. Situations that caused nurses to experience moral distress included inappropriate care behavior was not guaranteed the quality of nursing care, conditions related to unethical the human rights, conditions related to the lack of nursing staff and conditions related to the lack of support at the organizational and national level. Therefore, to reduce moral distress, nursing intervention programs that improve the moral sensitivity and ability to solve ethical-problems are needed for nurses working in long-term care facilities.

This paper focuses on the geographical pattern of financial activities in the Korean urban system during 1975-1990, based on the assumption that financial activities can reveal control points in Korea's urban economy. In terms of spatial evolution of financial insitutions, different locational characteristics are revealed among different types of financial institutions, implying the role of urban hierarchy. Financial resources are highly concentrated in the capital region, Seoul and Kyonggi Province. Both centralization trends into the large metropolitan cities and relative declines of medium and small cities within the Korean urban system, have been experienced over the study period. Financial activities sustain relatively stable hierarchical structure in the urban hierarchy. Regarding the financial flows, dominant flow zones centered on major metropolitan cities are identified, clearly showing a prominant role of Seoul in financial flows in the entire urban system.

Wedge filter could use to increase the dose distribution at the hot dose regions. We evaluated dose discrepancy at surface and build region in the infield and outfield that Metal Wedge (MW) and Enhance Dynamic Wedge (EDW) were interact with photon. In this paper, we used Gafchromic EBT3 film that had excellent spatial resolution, composed the water equivalent materials and changed the optical density without development. The set up conditions of linear accelerator were fixed 6 MV photon, 100 cm SSD, $10{\times}10cm^2$ field size and were irradiated 400 cGy at Dmax. The dose distribution and absorbed dose were evaluated when we compared the open field with $15^{\circ}$, $30^{\circ}$, $45^{\circ}$ metal wedge and enhanced dynamic wedge. A $15^{\circ}$ metal wedge could increase the surface and build up region dose than using a $15^{\circ}$ enhanced dynamic wedge. A $30^{\circ}$ metal wedge could decrease the surface and build up region dose than using a $30^{\circ}$ enhanced dynamic wedge. A $45^{\circ}$ metal wedge could decrease by large deviation the surface and build up region dose than using a $15^{\circ}$ enhanced dynamic wedge. The dose of penumbra region at outfield were increased on the thick side but were decreased on the thin side. It could be decrease the surface dose and build up region dose, if the metal wedge filters were properly used to make a good dose distribution and not closed the distance of surface.
