Purpose: The purpose of this study was to investigate sexual communication among college student couples and to analyze the relationship among sexual communication, sexual attitude, sexual autonomy and sexual satisfaction. Methods: Using a descriptive correlation study design, 281 college student couples were recruited through convenience random sampling from September 18th to October 3rd, 2014. Data were analyzed using average, standard deviation, percentage, t-test, ANOVA, Scheffe test, Duncan’s test and Pearson’s correlation using the SPSS 21.0 program. Results: In both genders, it is identified that high scores for sexual communication is related to sexual openness (male: R= .347, p<0.01 / female: R=.337, p<0.01) higher sexual satisfaction (male: R= .349, p<0.01 / female: R=.336, p<0.01) and sexual autonomy (male: R= .336, p<0.01 / female: R=.364, p<0.01). The same outcome is found when each male and female are grouped as a couple. Among sub-categories of sexual attitude, sexual pleasure was related to sexual communication the most in male (R=.337, p<0.01), female groups (R=.317, p<0.01) and couples (R=.402, p<0.01). Among sub-categories of sexual satisfaction, psychological factor was related to sexual communication the most in the male group (R=.342, p<0.01) and interactive factor was related to sexual communication the most in the female group (R=.317, p<0.01) and couples (R=.402, p<0.01). Conclusion: The significance of this research is that the relations of sexual communication with the other three dependent variables among each gender and couples are shown. In addition, this study suggests the importance of sexual communication between couples which will lead to healthier and better quality of sexual relationships. However, with the lack of sufficient advanced research, there are limitations of analyzing each variables divided by demographic characteristics.

<P>The cytogenetic and molecular data is recognized as the most valuable prognostic factor in acute myeloid leukemia (AML). Our aim was to systemically analyze the cytogenetics of Korean AML patients and to compare the cytogenetic profiles of various races to identify possible geographic heterogeneity. We retrospectively reviewed medical records of 2806 AML patients diagnosed at 11 tertiary teaching hospitals in Korea between January 2007 and December 2011. The most common recurrent chromosomal abnormality was t(8;21) (8.8 %, 238/2717), but t(15;17) showed an almost same number (8.6 %,235/2717). Among de novo AML, the most frequent aberrations were t(15;17), observed in 229 (10.7 %). The most common French-American-British (FAB) classification type was M2 (32.2 %), and recurrent cytogenetic abnormalities correlated with the FAB subtypes. Among 283 secondary AML cases, myelodysplastic syndrome was the most common predisposing factor. About 67.1 % of the secondary AML cases were associated with chromosomal aberrations, and chromosome 7 abnormalities (n = 45, 15.9 %) were most common. The incidence of FLT3 internal tandem duplication mutation was relatively low at 15 %. Our study reports certain similarities and differences in comparison to previous reports. Such discrepancies call for extensive epidemiological studies to clarify the role of genetic as well as geographic heterogeneity in the pathogenesis of AML.</P>
Amantadine-resistant influenza A viruses isolated in South Korea from 2003 to 2009

To investigate the frequency of amantadine resistance among influenza A viruses isolated in Korea during the 2003-2009 seasons, 369 (16.8%) 2199 A/H1N1 viruses and 780 (14.8%) of 5263 A/H3N2 viruses were randomly selected. The M2 and HA1 genes of each isolate were amplified by reverse transcription-polymerase chain reaction and followed by nucleotide sequencing. The results showed that the resistance rate to amantadine among A/H1N1 viruses increased significantly from 2004-2005 (33.3%) to 2007-2008 (97.8%) and then decreased dramatically in 2008-2009 (1.9%). The A/H1N1 isolates recently detected in 2008-2009 turned amantadine-sensitive containing two new substitutions at specific sites (S141N, G185A) in HA1. Compared with A/H1N1 viruses, the amantadine resistance among the A/H3N2 viruses increased from 2003-2004 (9.7%) to 2005-2006 (96.7%) and decreased in 2006-2007 (57.4%). During 2006-2007, both of amantadine-resistant and -sensitive A/H3N2 viruses co-circulated but clustered in different branches phylogenetically. All of A/H3N2 isolates tested during 2007-2009 appeared to cluster in the same group being resistant to amantadine.

<P>Fast water flow facilitates ferrous ion transport leading to flow accelerated corrosion (FAC) of carbon steel and the possibility of a large accident through a failure of a secondary pipe in a nuclear power plant. Ion transport is directly linked to oxide properties such as the thickness, chemical composition and porosity. This work deals with a precise observation of the cross section of the corroded specimen focusing on an oxide passivity and its thickness using SEM (scanning electron microscope) and TEM (transmission electron microscope) as well as an apparent weight loss and a surface observation for the specimens corroded using a rotating cylindrical electrode autoclave system in pure water of pH 7 at 150 degrees C having dissolved oxygen below 1 ppb within a flow rate range of 0 to 10 m/s. The Cr content in steel was changed from 0.02 to 2.4 wt%. Increasing the Cr content in the alloy, the FAC rate and oxide thickness decreased. The oxide porosity tends to decrease with the Cr content and immersion time owing to the development of Cr containing oxide. The oxidation behavior is not changed with the immersion time.</P>

Interfaces, both grain boundaries and phase boundaries, play a very important role in the mechanical behavior of structural materials. The problems particularly intense in composite materials where interfaces play a primary role in the mechanical response of the composites. This paper will concentrate on the approaches to perform nondestructive evaluation of the interfaces in a manner in which some measure of the mechanical behavior of the interface can be established. Some of the possible approaches that may potential for the nondestructive evaluation of interfaces are optical, electronic/electrical, and acoustic approaches.

The multi-frequency eddy current technique has been used for evaluation of various type of defects in tubings. However, this technique is not sufficient to detect and evaluate the defect in tubings if the defect is located in the geometrically complicated area(e. g. tube support plate, anti-vibration bar, tubesheet area) and mixing residue signal is significant to the defect signal. In order to improve the reliability of the multi-frequency eddy current technique, the effect of the interaction of mixing residue after frequency mixing with a function of distances between the defect and the tube support plate boundary has been analyzed theoretically. The experimental results have been discussed with the theoretical developments. The calculation shows the interaction between the two neighboring signal sources could be significant within the range of approximately 1.0mm with the experimental condition.

The integral model for the eddy current phenomena has been suggested. The model could lift the limitations of the previously well-known analytical model of eddy current theory. The model could be applied to two-dimentional, arbitary shaped defects. The computer programs have been developed in oder to calculate the eddy current signal with the suggested integral method. The eddy current signals by the model calculations have been shown similar patterns to the actual experimental data from the real defects in the calibration standard tubes.
