이 연구는 사회 감시견과 상호작용성의 차원에서 살펴 본 기자 블로그의 저널리즘적 특성이 전문기자 블로그와 시민기자 블로그 간에 어떻게 다르게 나타나는지를 비교 분석하였다. 사회의 감시견은 블로그 콘텐츠의 연성화 정도와 내용에 반영된 언론과 정부와의 관계의 측면에서 분석하였고, 상호작용성은 댓글 분석을 통해 규명하였다. 분석대상은 대표적인 시민기자 신문인 <오마이뉴스>와 이와 유사한 이념적 지향성을 지닌 <한겨레>의 전문기자 블로그다. 분석 결과, <오마이뉴스> 시민기자 블로그의 게시물이 <한겨레> 전문기자 블로그 게시물 보다 연성뉴스를 더 많이 다루고 있었으나 정부와 상호 비판적인 견제관계를 유지하는 경향이 상대적으로 강하게 드러나 시민기자 블로그와 전문기자 블로그가 서로 다른 측면에서 사회 감시견의 특성을 보여준다는 사실이 드러났다. 그리고 기자 블로그 게시물에 달린 댓글을 분석하여 파악한 상호작용성은, 댓글의 단순한 상호작용은 <오마이뉴스>에서 더 활발하게 이루어졌으나, 소통적 상호작용은 <한겨레>에서 더욱 강하게 나타난다는 결과를 얻었다.

IMT-2000 service started around year of 2000 to support global roaming with high speed data rate. But 3GPP and 3GPP2 could not narrow gaps between them to make separate specification. To make it worse, economy regression delayed deployment. Starting 2007, WCDMA, standardized in 3GPP, was launched in Korea by KT and SKT. 3GPP introduced HSDPA and HSUPA as an enabler for high speed down and uplink packet service, in release5 and release5, respectively.

This paper presents a novel shunt radio frequency microelectromechanical system switch on a quartz substrate with stiff ribs around the membrane. The buckling effects in the switch membrane and stiction problem are the primary concerns with RF MEMS switches. These effects can be reduced by the proposed design approach due to the stiffness of the ribs around the membrane. A lower mass of the beam and a reduction in the squeeze film damping is achieved due to the slots and holes in the membrane, which further aid in attaining high switching speeds. The proposed switch is optimized to operate in the k-band, which results in a high isolation of -40 dB and low insertion loss of -0.047 dB at 21 GHz, with a low actuation voltage of only 14.6 V needed for the operation the switch. The membrane does not bend with this membrane design approach. Finite element modeling is used to analyze the stress and pull-in voltage.

Purpose: This study was conducted to investigate the relationships among communication competence, professional self-concept, and stress in clinical practice of nursing students. Methods: The study participants were 308 senior year nursing students in D city and K province. Collected data were analyzed using t-tests, analysis of variance, Pearson's correlation coefficient, and stepwise multiple regression with the SPSS Version 20.0. Results: There were significant differences in participants' stress of clinical practice based on their level of satisfaction on clinical practice, self-confidence of nursing and difficulty with relationships in clinical practice. A negative correlation was detected between stress in clinical practice and the professional self-concept of nursing students. Significant predictors of the perceived stress of clinical practice were satisfaction in clinical practice and pride in nursing. These accounted for 18% of the perceived stress of clinical practice in a regression model. Conclusion: The results may serve as basic data in support of the need to the develop effective systematic stress management programs and clinical training courses in order to attenuate the stress experienced during clinical practice of nursing students.

Even through many professional organizations increasingly use Q&A sites in their online communities for information sharing, there are few studies which examine what is really going on in the Q&A activities in professional online communities (POC). This study aims to examine the interaction patterns and contents posted in the Q&A site of a POC, KOSEN, a science and technology online community in South Korea, focusing on how actively scientific information and knowledge are shared. The interaction patterns among the participants were identified through social network analysis (SNA) and the contents in the Q&As were examined by content analysis. The results show that the overall network indicated a moderate level of participation and connection and answerers especially tended to be active. Also, there are different interaction patterns depending on academic fields. Relatively few participants were posting leaders who seemed to steer the overall interactions. Furthermore, some content related to manipulation and explanation for experiments, which are in urgent need, seem to be posted in the sites more frequently with more amounts. Combining both SNA and content analysis, this study demonstrated how actively information and knowledge is shared and what types of contents are exchanged. The findings have practical implications for POC managers and practitioners.

The purpose of this study was to serve as a basis for mapping out successful strategies to build the professional self-image of nurses through uniform, by examining their satisfaction with uniform and professional self-image by general characteristics, and identifying the correlational relationship between the two factors. The subjects in this study were 205 nurses who served in general departments of two university hospitals in Seoul. The departments where special uniform was required, including ICU, RR, OR and CSR, were excluded. The data were collected from September 15 through 22, 2000. For measurement of uniform satisfaction level, a uniform satisfaction scale was prepared by myself, and Arthur(1990)'s PSCNI translated and modified by Song Kyong Ae and Rho Chun Hee(1996) was employed. The Cronbach a of the uniform satisfaction scale and PSCNI was 0.90 and 0.86 respectively. The collected data were analyzed by SAS, and real number, percentage, average and standard deviation were calculated. Besides, t-test, one-way ANOVA, Pearson's r procedures were utilized, and Scheffe test was conducted as a posttest. The findings of this study were as below: 1. The uniform satisfaction of the nurses investigated was scored 2.52 on the basis of 4 points, which was on the medium level. By subarea, symbolicity satisfaction was 2.48, and aesthetic satisfaction was 2.60. The functionability satisfaction was 2.44. So the esthetic satisfaction was greatest. 2. Among general characteristics of the subjects, two factors made a significant difference to their uniform satisfaction : age(F=4.05, P=.0189), and total career(F=4.25, P=.0061). 3. Their professional self-image got 2.75 on the basis of 4 points, which was on upper middle level. The subarea score was 2.79 for professional work, 2.52 for satisfaction and 2.97 for communication. The communication area was rated highest, and the satisfaction area was scored lowest. 4. Among the general characteristics of the subjects, professional self-image was different according to five factors : age(F=17.83, P=.001), marital status(T=5.18, P=.0000), educational background(F=8.72, P=.0002), position(T=-5.29, P=.0000) and total career(F=15.23, p=.0001). Better professional self-image was possessed by the older group than the younger one, by the married group than the singles, by the better-educated group than the less-educated, by the nurses in position equal to or higher than charge nurse, or by the higher-career group. 5. The correlational relationship of uniform satisfaction to professional self-image was statistically significant, yet very weak(r=.1978, p=.0045). The satisfaction area of professional self-image was correlated to every uniform satisfaction area, including symbolicity(4=.4393, p=.0001), aesthetics(r=.2471, p=.0004), functionability(r=.3094, p=.0001) and total satisfaction(r=.4050, p=.0001). Therefore, the uniform satisfaction gave an impact on the satisfaction area of professional self-image of the nurses, and there was a significant correlational relationship between uniform symbolicity area and total professional self-image(r=.2416, p=.0005).

In a specialized modern society and/or visual communication technique seems to be preferable to the traditional one-way communication technique which resorts to reading materials. P.R materials currently produced by various levels of Korean government administrative bodies seem to outdated and inefficient both in their contents and in graphic technique employed. In this paper we argue that the problems of the communication technique used by Korean government result mainly from the ambiguous nature of the message of P.R materials and the inability to differentiate the contents of P.R materials according to the target audience. We recommend various changes to the current government communication program and emphasize the importance of graphic communication technique for the production of more effective and professional communication materials
