<P>ABSTRACT</P><P>We report the discovery of a multiple system with a quadruple-lined spectrum and a double eclipsing feature. Our photometric and high-resolution spectroscopic data show that V994 Herculis (V994 Her; ADS 11373 AB) is composed of two pairs of double-lined eclipsing binaries, which we designate as A and B. System A consists of a B8V+A0V binary with an orbital period of 2.083 264 d and system B of a A2V+A4V binary with 1.420 033 d. Our light curves show that both of them have a detached binary configuration. We derive masses and radii of four components (Aa, Ab, Ba and Bb) from the synthetic analyses of light curves and radial velocity curves. The masses of systems A and B are <I>M</I><SUB>Aa</SUB>= 2.83 ± 0.20 M<SUB>⊙</SUB>, <I>M</I><SUB>Ab</SUB>= 2.30 ± 0.16 M<SUB>⊙</SUB>, <I>M</I><SUB>Ba</SUB>= 1.87 ± 0.12 M<SUB>⊙</SUB> and <I>M</I><SUB>Bb</SUB>= 1.86 ± 0.12 M<SUB>⊙</SUB>, with radii <I>R</I><SUB>Aa</SUB>= 2.15 ± 0.05 R<SUB>⊙</SUB>, <I>R</I><SUB>Ab</SUB>= 1.71 ± 0.04 R<SUB>⊙</SUB>, <I>R</I><SUB>Ba</SUB>= 1.59 ± 0.08 R<SUB>⊙</SUB> and <I>R</I><SUB>Bb</SUB>= 1.50 ± 0.08 R<SUB>⊙</SUB>, respectively. These masses and radii are well consistent with the empirical relation for double-lined eclipsing binaries.</P>

This study was conducted to investigate the differences in the degrees of career attitude maturity according to the clinical practice experience of the college of nursing students. The convenience sample was 275 students attending the college of nursing in Seoul. Data was obtained through a questionnaire from December 1st to 12th, 2008. The instrument used to measure the career attitude maturity in this study was "A barometer of maturity in career attitudes" developed by Ki-hak, Lee(1997). The collected data were analyzed by descriptive statistics, Chronbach's alpha, t-test and ANOVA with the SPSS 16.0 program. Below is the result of this study. 1. The average score for career attitude maturity of nursing students who experienced clinical practices was 135.56(±12.17): higher than the average score of inexperienced students, 134.37(±12.44). However it could not show meaningful differences in the statistics(F=-.805, p=.422). 2. Determinacy, one of five subordinate concepts of career attitude maturity, was statistically significative. On average, the group comprised of students with clinical practices scored 27.60(±3.81): higher than that of unpracticed students, 26.63(±4.26)(F=-1.976, p=.049). 3. The more academic years they have, except for junior year students, the points of career attitude maturity relative to general characteristics were increasingly higher. The points were 132.60(±11.99) for freshmen, 135.93(±12.72) for sophomores, 133.50(±12.57) for juniors and 138.11(±11.24) for seniors(F=2.714, p=.045). 4. According to the age of the group, the grade of career attitude maturity became higher. The scores were 133.21(±12.34) for 18-19yrs., 134.05(±12.16) for 20-22yrs., 138.43(±10.96) for 23-26yrs. and 148.71(±12.76) for 27-32yrs. (F=5.118, p=.002). 5. The average total score for career attitude maturity of nursing students was 135.00(±12.30). Of the five subdivisions―readiness, conviction, determinacy, independence and finality― readiness demonstrated the highest result with 32.33(±4.46) followed by conviction, determinacy, independence and finality respectively. Based on the results, there are some proposals for further researches. As this research was only for college of nursing in Seoul, it is necessary to compare career attitude maturity with 3-year colleges and other departments. In addition, alongside clinical practices there is a growing need to develop programs that will not only provide guidelines but also prepare students for the maturity of their career attitude.

We conducted a cross‐sectional telephone survey for women who had obtained a National Cancer Screening Programme mammographic screening at general hospitals between May and October 2008. The present study included 2005 women in their forties. We performed multivariate linear regression using dependent variable as general satisfaction and independent variables as subscales of satisfaction, such as pre‐screening information transfer, staff interpersonal skills, physical surroundings and results reporting. Participants were stratified according to the result of their mammogram as negative or positive. Mean score of satisfaction was above 2.5 of 4 for all subscales. Women who received positive results were less satisfied with all of subscale factors. Staff interpersonal skills were the most important factor that contributed to general satisfaction. Future efforts such as staff training programme of communication/attitude skills, ensuring privacy and explanation of possible discomfort of the screening would be needed.</P>

Kim, A.,Kwon, O. S.,Kim, S. O.,He, L.,Bae, E. Y.,Lee, M. S.,Jeong, S. J.,Shim, J. H.,Yoon, D. Y.,Kim, C. H.,Moon, A.,Kim, K. E.,Ahn, J. S.,Kim, B. Y. Blackwell Publishing Ltd 2008 Cell proliferation Vol.41 No.5

<P>Abstract. </P><P><I>Objectives</I>: Nuclear factor-kappa B (NF-&kgr;B) activation has been associated with the tumorigenic growth of hepatitis B virus X protein (HBx)-transformed cells. This study was aimed to find a key target for treatment of HBx-mediated cancers. <I>Materials and methods</I>: NF-&kgr;B activation, endoplasmic reticulum-stress (ER-stress), caspase-3 activation, and cell proliferation were evaluated after Chang/HBx cells permanently expressing HBx viral protein were treated with inhibitors of NF-&kgr;B, proteasome and DNA topoisomerase. <I>Results</I>: Inhibition of NF-&kgr;B transcriptional activity by transient transfection with mutant plasmids encoding Akt1 and glycogen synthase kinase-3&bgr; (GSK-3&bgr;), or by treatment with chemical inhibitors, wortmannin and LY294002, showed little effect on the survival of Chang/HBx cells. Furthermore, I&kgr;Bα (S32/36A) mutant plasmid or other NF-&kgr;B inhibitors, 1-pyrrolidinecarbonidithioic acid and sulphasalazine, were also shown to have little effect on the cell proliferation. By contrast, proteasome inhibitor-1 (Pro1) and MG132 enhanced the HBx-induced ER-stress response and the subsequent activation of caspase-12, -9 and -3 and reduced cell proliferation. Camptothecin (CPT), however, triggered activation of caspase-3 without induction of caspase-12, and reduced cell proliferation. In addition, CPT-induced cell death was reversed by pre-treatment with z-DEVD, a caspase-3-specific inhibitor. <I>Conclusions</I>: Detailed exploitation of the regulators of caspase-3 activation could open the gate for finding an efficient target for development of anticancer therapeutics against HBx-transformed hepatocellular carcinoma.</P>

Purpose: The purpose of this study was to determine the sexual knowledge, and sex education perception and current status of the parents of preschoolers. The objective was to analyze the relationship between sexual knowledge and sex education demands of parents. Method: The method used in this study was a descriptive correlationstudy. The subjects were 278 parents of 3-to-6 year old children in 5 kindergartens located in Seoul. Data were analyzed using frequency, percentage, average, standard deviation, t-test, ANOVA, Scheffe test, and correlation using the SPSS 20.0 program. Result: The results of this study were the following: 1.There was no significantdifference in the sexual knowledge between the father and mother of preschoolers (Father 20.76, Mother 20.73). According to the findings, sexual knowledge was higher when both father and mother were older (P=.005). Similarly, when the economic level of the father and mother was high, sexual knowledge was also high (P=.030). 2.Concerning sexual education perception, it was found out that both father and mother thought that sex education was necessary. 3.In terms of sex education, a significant difference was noted. Mothers conducted sex education more often than fathers (Fathers, 46.7% Mother, 60.3%). Both the father and mother thought that providing sex education would be best in Grades 1-2, especially for ages 6-7. 4.When asked about the demands for sex education in terms of the physical, social, and living aspects, living aspect was the highest demand. It was revealed that both fathers and mothers were aware of the need for sex education, and when parents hadmore sexual knowledge, they would demand more sex education. Accordingly, there was a correlation between parent’s sexual knowledge and demand for sex education (r=.202, p=.001). Conclusion: Since the age,knowledge, education and economic levels of parents were different, it was necessary to develop sexeducation programs in accordance with their levels. In this way, preschooler parents would be able to teach sex education appropriate to their children’s level.

The stability of alumina-coated NiO cathodes was studied in Li 0.62 /K 0.38 molten carbonate electrolyte. Alumina was effectively coated on the porous Ni plate using galvanostatic pulse plating method. The deposition mechanism of alumina was governed by the concentration of hydroixde ions near the working electrode, which was controlled by the temperature of bath solution. Alumina-coated NiO cathodes were formed to A1 2 O 3 ?NiO solid solution by the oxidation process and their Ni solubilities were were than that of NiO up to the immersion time of 100h. However, their Ni solubilities increased and were similar to that of the bare NiO cathode after 100h. It was because aluminum into the solid solution was segregated to α?LiAlO 2 on the NiO and its Product did not Play a role of the Physical barrier against NiO dissolution.
