Recently the hair style of Michelle Obama, the world's most recognized First Lady of the United States has been loved by the public with her optimistic confidence and as a fashion leader. For Michelle Obama's hair styles by length, a medium-short cut style was expressed in various ways to show her strong will by exposing the forehead, an elegant image by asymmetry hair, or a progressive image by a short volume hair cut. A medium cut style expressed an elegant and intelligent image in shoulder-length and a trendy image using a side parting. A updo hair style produced young, womanly, and casual images using twisting, binding, typing up, and rolling technique according to situations. For hair styles associated with her roles, when participating as a diplomatic delegate, she expressed the President's helpful partner by a soft and womanly image using bobbed hair and half updo technique. For the participation in state occasions, her hair styles were examined in three situations. First of all, she mainly had a neat style, exposing her forehead in official schedules as a political partner to create an intelligent and high-class image. Second, she expressed a strong will with a medium-short style during an election campaign. Finally, she showed an elegant and refined hair style in consideration of T.P.O. during social activity. Michelle Obama overcame her hair's handicap, grasped her images associated with hair length, and expressed hair strategically according to her roles as the first African-American First Lady of the United States.

In sport programs, real-time virtual imaging system come into notice for new technology which can compose information like team logos, scores. distances directly on playing ground, so it can compensate for the defects of general character generator. In order to synchronize graphics to camera movements, generally two method is used. One is for using sensors attached to camera moving axis and the other is for analyzing camera video itself. KBS technical research institute developed real-time sensor-based virtual imaging system 'VIVA', which uses four sensors on pan, tilt, zoom, focus axis and controls virtual graphic camera in three dimensional coordinates in real-time. In this paper, we introduce our system 'VIVA' and it's technology. For accurate camera tracking we calculated view-point movement occurred by zooming based on optical principal point variation data and we considered field of view variation not only by zoom but also by focus. We developed our system based on three dimensional graphic environment. so many useful three dimensional graphic techniques such as keyframe animation can be used. VIVA was successfully used both in Busan Asian Games and 2002 presidential election. We confirmed that it can be used not only in the field but also in the studio programs in which camera is used within more close range.

Recently, the need of researches and developments about WSN(Wireless Sensor Network) technologies, which can be applied to services that require continuous monitoring or services to specific areas where accesses are limited, has gradually increased due to their expansion of application areas and the improvement of the efficiency. Especially, in the defense field, researches on the latest IT technologies including sensor network areas are actively conducted as an alternative to avoid the risk factors that can be occurred when personnel are put in, such as boundary and surveillance reconnaissance and to utilize personnel efficiently. In this paper, we analyze the conditions for increasing the life span of sensing nodes that make up sensor network by applying clustering and location-based techniques and derived the factors for extending the life span of them. The derived factors include CH(Cluster Head) election scheme and optimal path selection from CH to BS(Base Station). We proposed final scheme using derived factors and verified it through simulation experiments.

Boophilus microplus (Canestrini, 1887) female specimens were subjected to scanning electron microscopy for the observation of surface fine structures. Morphological characteristics observed were summarized as follows: 1. The palpi were wider than long, and compressed, ridged dorsally and laterally. There were usually four pairs of ventro-internal setae on the articles. 2. The hypostome dentition was usually 4/4 but occasionally 5/5. 3. The basis capituli were hexagonal dorsally and the porose area was distinct with the holes developed well. 4. There were numerous folds resembling finger prints around the female genital pore. 5. A pair of anal lobes with specified setae on them was also rocognized as one of the morphological characteristics.

Ba-ferrite particles added with Co and Ti, which were known well the additives for the control in coercivity, were synthesized by sol-gel method. In the range 90 to 120 minute reaction time, a stable sol solution which showed no change with temperature, pH, viscosity and aging time. After dried and heat treatment of sol solution, Ba-ferrite phase formed at $700^{\circ}C$ with Differential Thermal Analysis(DTA) and X-Ray Diffractometer(XRD) measurement. The crystallinity became to be better with increasing the temperature. It were showed by Scanning Electron Microscopy(SEM) that Ba-ferrite increased to particle sizes as increasing heating temperature and obtained of narrow particles size distribution. Also, magnetic characteristics of Ba-ferrite powders Co and Ti added were observed by a Vibrating Sample Magnetometer(VSM). Saturation magnetization$(M_s)$ was not much changed, however. the coercivity$(H_c)$dramatically dropped with addition of Co and Ti.

This research has been performed in order to investigate the probability that cultural factors in everyday life affect individuals' political behaviors. Using the data collected from 2014 Seoul mayoral election, it analyzes how the degree to which individuals have various cultural capital influences their types of political information acquisition through media. The outcomes suggest following three. First, the more cultural capital individuals have, the more active they are in obtaining political information using diverse media. Second, those who mark high score in the self-cognitive area of cultural capital, such as cultural preferences and cultural tastes, tend to gather political information throughout formal news-oriented media such as on-line news, TV, and newspapers. Third, when types of media are classified into old and new, those who have a variety of cultural capital are likely to prefer new media as their major source of political information acquisition.

Purpose: The purpose of this study was to identify how political interest, efficacy and media usage influence political participation in hospital nurses. Methods: Participants were 286 nurses, who were informed of the study purpose and agreed to participate. Data were collected during November and December, 2012 using a questionnaire on political interest, political efficacy, media usage and political participation. Data were analyzed using t-test, ANOVA, Scheff$\acute{e}$'s test, Pearson Correlation Coefficients, and Multiple Stepwise Regression. Results: Scores for political participation and political interest was average. The score for political efficacy was higher than average. Political participation was significantly different by education level, job career, position, and intention to vote in the election for the 18th President. Political participation had a moderate positive correlation with political interest (r=.50, p<.001), political efficacy (r=.32, p<.001) and media usage (r=.14, p=.022). Political interest (${\beta}$=.43) was the factor most influential on political participation, explaining 25% of the variance. A total of 32% of political participation was explained by political interest, political efficacy, and TV news or SNS for media use. Conclusion: The results suggest that it is necessary to develop strategies to promote political interest and political efficacy for hospital nurses to improve political participation.

Many P2P systems which are designed to implement large-scale data sharing have been introduced in internet recently. They exhibit interesting features like sell-configuration, sell-healing and complete decentralization, which make them appealing for deployment in ad hoc environments as well. This paper proposes an Gnutella-based P2P system that can operate efficiently in ad hoc networks. The objectives of this paper are to extend the overall system lifetime, to reduce overheads, and to provide enhanced performance. The proposed system uses an ultrapeer election scheme based on metric values and proactive distribution of ultrapeer information. According to the simulation results, the proposed system can provide better performance than Gnutella in terms of query success rate, query response time, overhead and residual battery power by utilizing network resources efficiently.
