Purpose: The purpose of this study was to identify the factors influencing personal disaster preparation and disaster nursing core competency among visiting nurses in public health centers. Methods: A descriptive survey study was adopted. A convenience sample was taken from 277 subjects in three regions. Data were analyzed by descriptive statistics, t-test, ANOVA, correlation, Pearson correlation coefficient and multiple regression. Results: The mean personal disaster preparation and disaster nursing core competency scores were 11.13 and 76.87, respectively. Personal disaster preparation was statistically significant by experience of disaster victims and disaster management guideline. Disaster nursing core competency was statistically significant by participation in future disaster recovery. As a result of multiple regression analysis, personal disaster preparation accounted for 14.9 of the variance by experience of disaster victims and disaster management guidelines; disaster nursing core competency accounted for 8.9 of the variance by perception of disaster nursing. Conclusion: Although visiting nurses are ill-prepared for disaster, global natural and man-made disasters can occur regardless of time and place. Disaster education and training should therefore be included in nurses' fundamental education.

Determination method of optimum feeding point for the PIFA type internal antenna for the mobile phone handset was studied. Fundamental theory is that radiated gain is basically depended upon the electric field strength between PIFA conductor and ground plane. Feeding point, slit configuration, material and structure of carrier are main factors fur the PIFA performances. It is shown that maximum electric field strengths of other feeding points decrease in -2dB to -10 dB than optimum point. Ansoft HFSS EM simulator was applied to determine the best feeding point for 2 models of Samsung Electronics mobile phone handset.

We have studied the effect of crystallization temperature, composition and film thickness, which are the fundamental processing parameters of lead zirconate titanate(PZT) thin film fabrication, in the respect of the piezoelectric properties by our pneumatic loading method(PLM). A great deal of research has been done in the field of characterization for piezoelectric thin films after the first report on the measurement for the piezoelectric coefficient of thin films in 1990. Even though the piezoelectric properties of thin films are very critical factors in the micro-electro mechanical system(MEMS) and thin film sensor devices, a few reports for the piezoelectric characterization are provided for the last decade unlikely the bulk piezoelectric devices. We have found that the piezoelectric properties of thin films are improved as the increase of crystallization temperature up to 750$\^{C}$ and this behavior can be also explained by the analysis of dielectric polarization hysteresis loop, X-ray diffraction and scanning electron microscopy. The effect of Zr/Ti composition has been also studied. This gives us the fact that the maximum piezoelectricity is found near Morphotropic Phase Boundary(MPB) as bulk PZT system does.

The study on the analytical and productive methodolgy of visual culture contents is meaningful because cultural contents are regarded as a national growth industry. The fundamental notion of cultural contents is researched based on the notion of visual culture, and important factors of the fun are analyzed as a creative motive of visual culture contents. So this paper provides anaytical methodologies for the fun in visual culture contents, which are based on semiotic theories of Charles Morris, Roland Barthes and Roman Jakobson. These analytical matrix can be references for the study of the mechanism of fun and the basic theory for using fun effects in the visual culture contents.

Open clusters consisting of a co-spatial and coeval population with a similar chemical composition are a superb astrophysical test bed in both stellar and galactic astronomy. We introduce not only several scientific issues relating to these objects but also comprehensive studies of the two young open clusters Westerlund 1 and IC 1848 formed in extremely different star-forming conditions. Westerlund 1 is known as the most massive starburst cluster in the Galaxy. Located in the Scutum-Centaurus spiral arm, the cluster is relatively close to the Galactic Center. The apparent surface density is very high. On the other hand, IC 1848 is a core cluster within the large-scale star-forming region W5 lying in the Perseus arm. Unlike Westerlund 1, IC 1848 with a putatively low metallicity exhibits a low surface density. We present the fundamental parameters of those young clusters, such as reddening, distance, and age, obtained from the broadband photometric analysis. The stellar initial mass function (IMF) of the clusters is used to investigate the effects of the different star-forming conditions on the star formation activity. With the results of previous studies for several young open clusters, our preliminary results support a possibility that star formation activity may be affected by the environmental factors or the initial condition of natal clouds. In addition, we shortly discuss the age scale and spread of pre-main sequence stars to understand the formation processes of star clusters.
