Signal words such as DANGER, WARNING, CAUTION, etc. have been used in order to transmit a potential hazard easily and quickly. But they were applied to a number of the sites without consistency. Thus, this study took Quantification Method and Cluster Analysis in order to judge the signal words corresponding to the urgency of situations, and to analyze whether signal words are used properly or not. According to the result of Quantification Method II signal words were most affected by Understanding, Severity and Likelihood in both student group and industrial worker group. And in Quantification Method III CAUTION corresponded to Immediacy and Understanding whereas NOTICE did to Receptivity, WARNING, DEADLY and DANCER did to Likelihood, Dangerousness and Severity. Finally, Cluster Analysis showed that CAUTION and NOTICE were recognized as similar words.

The Saemaul Mini-Library system had to start as a purely voluntary grass-roots movement without a tax su n.0, pport. In other words, it had to depend on voluntary contributions in time and labor by the reading club members for its finance and daily maintenance and operation. The purpose of the study is to analyse the actual condition of a Saemaul Mini-Library, which is established in a rural and a fishing village. To meet this purpose, I will survey the function and the meaning of a Saemaul Mini-Library and the main tendency of it-now did it start and how did it develop and I will analyse the general condition of structural factors (establishment, materials, reading club) in a Saemaul Mini-Library.

The karyotype of Lilium cernum has been analysed by means of C-banding technique. Most of clones observed were 2n=24 chromosomes which consist of two pairs of submetacentric and ten pairs of subtelocentric chromosomes, among which two pairs of chromosomes(B and E) showed secondary constriction in the short arm. In addition to these chromosomes a small supernumerary telocentric chromosome was seen in the eight clones. Sixtyeight bands were observed in the twentytwo chromosomes of complement and one band in the supernumerary chromosome. A pair of chromosome (L) did not show any band. The bnads on the chromosome. A pair of chromosome (L) did not show any band. The bands on the chromosomes were distributed in the centromere, secondary constriction and intercalary regions of arms. Of the twelve pairs of chromosomes ten pairs showed symmetric banding patterns in each, but two pairs (I and K) showed asymmetric banding patterns.

As the college environment changes, the roles of professors and students should also be changed. And the way that we teach undergraduate students should also be changed. The purpose of this research is to analysis characteristics of good teaching methods in college as perceived by students and professors. We did content analysis to elicit the characteristics of good instruction from qualitative comments of 196 course evaluations, 195 excellent essays selected from 8 college essay competitions, and 72 teaching knowhow essays of professors. To see the difference of division in good instruction characteristics, we did frequency analysis by SPSS statistics program. According to the content analysis, the most essential characteristics of good instruction as perceived by the students and professors is teaching strategies. There were also differences in the fact of recognition transition by division and the students-professors.

I used Principal Component Analysis(PCA) and Linear Discriminant Analysis(LDA) to utilize biometric technology for security. I used 14 korean consonants(ㄱ to ㅎ). And It has both information of gestures for each consonants and identity of user. So this experiment is set for this two aspects. I used database including 20 people's images. Each person did 140 action for every consonant with 10 trials. PCA and LDA must be applied on self-collected database using MATLAB programming. Equal Error Rate (EER) is used for evaluate performance of this analysis.

We investigate the effect of comment history disclosure on portal news comments. Specifically, based on the scraped news comments from Naver and Daum (two leading Korean news portals), we employ the difference-in-differences estimator to empirically tease out the impact of the comment history disclosure policy implemented in Naver on its news comments. Our result shows that the policy implementation significantly increased the length and the positiveness of online news comments but did not affect their quality.

In this paper, we are going to analyze on relation of an output spectrum along phase distortion of power amplifier in wireless LAN system, and then considered an ACPR characteristic of power amplifier and consideration of an OFDM method for this. Also, we did implementation for OFDM modulation and transmission section of an IEEE 802.11a standard to have transmission speed of the maximum 54Mbps in order to know an OFDM modulation method and relation of non-linear characteristic of power amplifier. The non-linear characteristic of power amplifier did modeling with AM-to-AM and AM-to-PM, and we analyzed an output spectrum characteristic along phase distortion composed input signal supply for power amplifier. When output spectrum analysis results phase distortion increased, and an AM-to-PM characteristic of power amplifier in 5 degrees, the output spectrum was satisfied with a demand spectrum in P1 dB, but 10-20 degrees were able to confirm what cannot be satisfied with a demand spectrum in phase distortion. Also, an output spectrum of power amplifier by frequency re-growth generated by a non-linear characteristic of power amplifier did not satisfied in P1dE. therefore, a back-off value was requested according to an AM-to-PM distortion degree, and smaller back-off value were able to know what demand became in case of modulation section that used OFDM.

This study was conducted to evaluate the necessity of the anchor lug system in continuously reinforced concrete pavement(CRCP) by comparing longitudinal displacements of CRCPs with and without anchor lugs, and to investigate the effect of horizontal cracking on CRCP performance by measuring the vertical displacements. The measurements before and after the anchor lug section was separated were conducted for 12 days in June, and for 14 days in August after the abrupt displacements according to cutting disappeared, respectively. This short term measurement results showed that when anchor lugs were installed, a daily displacement variation at any location was less than 0.1mm; therefore, longitudinal movements were negligibly small. When there were no anchor lugs, longitudinal displacements mainly occurred near the free end and the displacement variation was small; therefore, an expansion joint system seems to be employed at a CRCP terminus without installing anchor lugs. However, further studies are needed to verify the terminus behavior due to annual temperature changes. The horizontal crack width variation was ignorable and did not affect the vertical displacement of the slab. Therefore, the horizontal crack did not delaminate the slab and did not seem to reduce the structural capacity and performance of CRCP.

This paper analyzed experientially political conducts of the political players on privitization of healthcare service and public healthcare sercive aftrer the democratization in order to determine the influence of democracy on the development of a welfare state. For this purpose, the contents of the major daily newspaper reports from 1993 to 2012 were analyzed. As a result of such analysis, it was found that the political parties did not drive the policy even after the democratization reflecting the demands of the people, political parties had a strong conservative stance and did not show a consistent ideological inclination in their policies. Second, even though the role of the civic movement in the public healthcare service issue became larger after the democratization, policy decisions were driven by the government in an authoritative manner. In addition, the degree of contribution by the civic movements to the development of public healthcare service did not offset the influence of the president and the finance ministry on the development of privatization. Third, both the development of public healthcare service and privatization progressed simultaneously under the Kim Dae Jung, Rho Mu Hyun and Lee Myung Bak administrations after the democratization and it is thus difficult to argue that the qualitative nature as a welfare state was changed after the democratization. However, the degree of development as a welfare state differed depending on the ideological inclination of the presidents, the capacity of the welfare ministry and the ministry that drove the privatization.
