  • An efficient method for the rapid propagation of Smilax china from axillary buds was established. Plants with thick leafage were selected from Korea native S. china population. Axillary buds of S. china collected from selected plant and were cultured in various culture media (2MS, MS, 1/2MS, WPM, B5 and SH medium). Shoot was induced from axillary bud on MS basal medium after 4 weeks of culture. 1/2MS medium showed a higher growth rate than those of the others, while the lowest shoot growth was obtained in 2MS medium. Among the sucrose concentrations, 5% sucrose was the optimum level for shoots growth from axillay buds. Among cytokinins, $0.5mgL^{-1}$ 6-benzylaminopurine (BAP) treatment showed the best performance on shoot multiplication, yielding average shoot multiplication forming about 2.4. Rooting was induced directly near the base of the shoot on 1/2MS medium containing with three-auxins ${\alpha}-napthalene$ acetic acid (NAA), indole acetic acid (IAA) and ${\beta}-indolebutyric$ acid (IBA) (0.5 and $1.0mgL^{-1}$). The $1.0mgL^{-1}$ IBA treatments induced earliest rooting with maximum of root number and root growth. These rooted plantlets were successfully transferred to pots for 4 weeks hardening process, and were transferred to soil with above 90% survival rate.

  • The purpose of this study is to investigate the selection mechanism of the Science Citation Index(SCI) in domestic journals. Analysis has been carried out specially on the \"Journal of the Korean Nuclear Society\", which is a leading journal in the nuclear field in Korea. It is published in English and meets the basic standards of technical journal, however, does not meet the SCI selection criteria in many aspects. Major problems are; 1) Small number of research institutes and universities submit articles to the journal. 2) The impact factor is 0.097, far less than 0.764, the average value of SCI, and the rate of self-citation approaches only to 50%. 3) The journal is not distributed to the libraries in universities and research institutes that have nuclear engineering programs in foreign countries. 4) It does not have editor from international communities, only domestic editors serve for the journal. The study made recommendations for ways to be selected by SCI and utilization of this study for selection criteria of SCI.

  • The effect of doping Gd, La for Y into $YVO_{4}:Eu^{3+}$ red phosphor on its photoluminescence(PL) intensity has been investigated. $YVO_{4}:$Eu-based phosphors were prepared by solid-state reaction at temperature above $1200^{\circ}C$. Under UV excitation(254, 365 nm), it was measured that $YVO_{4}:Eu^{3+}$ was superior to a commercial red phosphor (Y,Gd)$BO_{3}:Eu^{3+}$ in terms of PL intensity and CIE color coordinates. When La, Gd were doped into $YVO_{4}:Eu^{3+}$, the change in the structure of the host material was observed. In result, when the ($Y{1_x}La_{x})VO_{4}:Eu^{3+}$ phosphors were excited by 365 nm excitation, its PL intensity was improved up to about 30 % for the case of x being $0.4{\sim}0.6$.
