  • Satsuma dwarf virus (SDV) or Citrus mosaic sadwavirus (CiMV) were not consistently detected in RTPCR assay with the primer sets based on gene of Japan isolates. SDV and CiMV isolates were distinctively divided into two groups based on phylogenetic analysis of PP2 gene cloned from 22 Korean isolates, and the Korean CiMV and SDV isolates shared 95.5-96.2% and 97.1-97.7% sequence identity with Japanese isolate, respectively. We developed PP2-1 primer set based on the PP2 gene sequence of Korean isolates to simultaneously and effectively detect SDV and CiMV. And CTLV-2013 and CTV-po primer sets were newly designed for detection of Citrus tatter leaf virus (CTLV) and Citrus tristeza virus (CTV), respectively. Using these primer sets, a new multiplex PCR assay was developed as a means to simultaneously detect 4 citrus viruses, CTV, CTLV, SDV, and CiMV. The degree of detection by the multiplex PCR were consistent with those of uniplex RT-PCR for detection of each of the viruses. Therefore, the new multiplex PCR provides an efficient method for detecting 4 citrus viruses, which will help diagnose many citrus plants at the same time. We verified that 35.2% and 72.1% of 775 trees in 155 orchards were infected with SDV or CiMV (SDV/CiMV) and CTV by the multiplex-PCR assay, respectively, and CTLV was not detected in any of the trees tested.

  • Purpose: The purpose of this study was to identify nurses' perceptions of the importance of concrete items as a basis for nursing practice. A total of 179 concrete items for basic nursing, which clinical nurses must know in order to practice appropriately, were identified. Method: The participants in this study were 225 nurses who had worked for two to five years in university hospitals. The nurses were asked to rate the importance of the 179 items (in 39 middle range categories) on a 5 point scale. Result: The mean age of the nurses was 26 and about 54% were university graduates. Of the 39 middle range categories those rated as the top ten were transfusion (4.682), IV injection (4.492), po medication (4.476), surgery (4.469), infection control (4.438), IM injection (4.413), safety (4.388), oxygenation (4.376), diagnostic test (4.366), and fluid & electrolyte balance (4.359). The categories that had the lowest scores were sexuality (3.449), conceptual nursing (3.465), spirituality (3.527) and personal hygiene (3.548). Conclusion: The results of this study show that most nurses evaluate items which they use frequently in their practice as important.

  • Low molecular weight copolymers of maleic anhydride and vinyl acetate were prepared to develop formaldehyde free cross-linking agents. Since lower molecular weight is favorable for efficient penetration of the finishing agent into the cotton fibers in the padding process, the concentration of the initiator, chain transfer agent and the monomer ratios were varied to obtain copolymers of low molecular weights. The prepared polymers were characterized by GPC, $^1{H-NMR}$, FTIR, DSC and TGA. Copolymers of molecular weights of 2 000 to 10 000 were obtained and it was found that the most efficient method of controlling the molecular weight was by varying the monomer ratios. Poly(maleic anhydride-co-vinyl acetate) did not dissolve in water, but the maleic anhydride residue hydrolyzed within a few minutes to form poly(maleic acid-co-vinyl acetate) and dissolved in water. However, the maleic acid units undergo dehydration to form anhydride groups on heating above ${160}^{\circ}C$ to some extent even in the absence of catalysts. The possibility of using the copolymers as durable press finishing agent for cotton fabric was investigated. Lower molecular weight poly(maleic anhydride-co-vinyl acetate) copolymers were more efficient in introducing crease resistance, which appears to be due to the more efficient penetration of the cross-linking agent into cotton fabrics. The wrinkle recovery angles of cotton fabrics treated with poly(maleic anhydride-co-vinyl acetate) copolymers were slightly lower than those treated with DMDHEU and were higher when higher curing temperatures or higher concentrations of copolymer were used, and when catalyst, $NaH_2$$PO_2$, was added. The strength retention of the poly(maleic anhydride-co-vinyl acetate) treated cotton fabrics was excellent.

  • Surface modifications are commonly utilized to adjust the properties of the titanium and its alloy surface to the specific needs of the medical applications, but there are disadvantages such as poor osteoconductive properties and low adhesion of bone cell to implant surface. In order to improve these disadvantages, changes in surface properties have an important effect on osseointegration during implantation. In this paper we applied new technological method for improving a unique surface modification using the characteristic of an electrolytic Solution. Thus, in the electrolyte containing NaF in Na2SO4, TiO2 nanoporous was uniformly formed, and HAp nanoparticles were electrodeposited around the TiO2 nanopores, but in the electrolyte containing NH4F in (NH4)H2PO4, the coarse protrusions including HAp nano particles were regularly deposited onto the TiO2 barrier layer. The surface characteristics and the distributed elements and have been investigated by EDS analysis, and ultra-fine structure of surface are carried out using FE-SEM. To investigate the behavior of the anion, the analysis of chemical states was performed by XPS, and the narrow spectrums for Ti2P, Ca 2p, and P 2p seems to be almost similar depending on the characteristics of the electrolyte solution respectively. In addition, Ca 2p spectrum could be resolved into two peaks for Ca 2p3/2 and 2p1/2 at 347.4 and 351.3 eV, which are related to hydroxyapatite. And, the P peak can also be deconvoluted into two peaks for P1/2 and P3/2 levels with binding energy 134.2 and 133.4 eV, respectively. From the result of soaking test, the apatite morphologys were well-formed onto the modified surface according to the different conditions.

  • Objectives : In order to make a new psychotherapeutic model in the theory of oriental medicine by means of psychoanalysis method. Methods : The research was done by comparing the contents of the Tong-Ui Po-Kam, techniques of Yang Saeng(養生術), with the psychoanalysis Results : 1. There's no difference in the mind state which a doctor has to have between the oriental doctor and the occidental doctor. You should make effort not to project yourself on a patient. A conception of 'doctor' in oriental medicine is one who trains one's mind rather than just healer. 2. Heart(心) in oriental medical conception is revealed by circulation structure of Jeong(精), Gi(氣), and Sin(神). A healthy mind comes from harmony and smooth transport of Jeong(精), Gi(氣), and Sin(神). 3. The conception similar to unconsciousness doesn't exist in oriental medicine, but the contents about the attitudes or the methods of training one’s mind correspond to unconsciousness. 4. The psychotherapy of oriental medicine emphasized mutual dynamics between emotions at present, and presented a way of treatment by describing emotions from standpoint of 'Gi(氣)'. 5. The special feature of psychological treatment in oriental medicine is that treatment is done by understanding emotions of present time as Gi (氣), and using dynamics of Gi (氣)(; 相生相剋). Also the balanced state can be kept even after treatment and prevention can be done by observing one's own unconsciousness(; training one's mind helps circulation of Jeong(精), Gi(氣), and Sin(神)) I think that we need a new realistic therapy model to develop these psychotherapy methods in oriental neuropsychiatry, through studying emotions in the theory of oriental medicine, especially Korean's emotions and spiritual training.

  • The purpose of this study is to clarify the adaptation of beauty of traditional dress depicted contemporary Korean fashion design. For this purpose, the external form and the internal meaning based on 'the double roots' proposed by W$\ddot{o}$lfflin were analyzed in Korean traditional dress. Documentary studies and objective studies were done with descriptive and content analytic methods. And homospatial process was devised in order to develop the traditional identity in contemporary fashion design. The results were as follows: 1. As the external form, H. O. A silhouette, chogori, ch'ima, paji, and po concerning internal type, kaftan, flat form related to structured type were represented. Traditional color sense were love of white, contrasting as well as analogous color harmony shown often in nature phenomena, and temperate achromatic color harmony. Texture were characterized as rough and coarse expressing vividness, fine and smooth expressing delicateness and tenderness. As the internal meaning, the beauty of purity related to nature, tragedy, and symbolism were represented. 2. Since 1980's. Korean fashion designers frequently applied unstructural kaftan form and H silhouette to Korean fashion design, and sought natural and pliable line in whole dress. Use of white and achromatic color harmony as well as use of linnen were prominent. Designers' aesthetic consciousness was pursuit of the beauty of nature. Representative designers who concentrated on expressing traditional beauty were Lee Shinwoo, Sul Yoonhyung, Jin Taiok and others. 3. A homospatial process could be a method in the creative design which enables to express Korean identity in fashion design, and could suggest ideas of new designs full of Korean identity by superimposed and fused imaginery.

  • The addition of a carbanion to ${\yen}{\acute{a}}{\yen}{\hat{a}}$-unsaturated carbonyl compounds is of importance in the C-C bond formation reactions for modern pharmaceuticals and organic synthesis. Recently, heterogeneous asymmetric catalysis became more attractive area of research because of the easy recovery and separation of the catalyst from the reaction system. Most of synthetic methods for heterogeneous catalysts were grafting or immobilization of homogeneous catalyst onto the solid supports. Trans-1,2-Diaminocyclohexane(DACH) and L-proline ligands have been enormously used as chiral ligands in several catalytic transformation under homogenous conditions. Our group prepared l-proline functionalized mesoporous silica was synthesized under acidic condition using a poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) triblock copolymer template (EO20PO70EO20, Pluronic P-123, BASF). Furthermore, we successfully directly synthesized trans-1,2 diaminocyclohexane functionalized mesoporous silica by using microwave method. The direct functionalization of chiral ligand into the framework of mesoporous materials is expected to be useful for the heterogeneous asymmetric catalysis. So, we adopt the direct synthesis of chiral ligand functionalized mesoporous silica by using thermal and microwave irradiation. Then, chiral ligand functionalized mesoporous silicas were applied to enantioselective asymmetric catalytic reactions.

  • 흙은 실제 비균질,비등방성이기 때문에 정확한 지반 특성을 파악하기는 쉽지 않다. 또한, 지반조사는 시간적, 경제적 측면에서 비효율적인 경우가 많다. 따라서, 본 연구는 지반조사의 효율적인 방법을 제시하기 위해 콘 관입치와 탄성속도에 대한 연약지반의 특성 파악에 적합한 장비로서 본 연구에서는 휴대용 원추형 콘관입시험기를 사용하였다. 휴대용 원추형 콘관입시험기는 조작이 편리하고 신속하게 지반상태를 파악할 수 있는 장점이 있다. 또한, 탄성탐사는 물리 탐사방법중 개략적 지반상태의 추정에 가장 많이 이용되는 방법으로 연약지반에 대한 이용이 계속 증가하고 있다. 콘저항치는 심도별 지층구성에 따라 일정한 군을 형성하였고 탄성파속도 또한 지층경계에 따라 일치하는 경향이 나타났다. 따라서, 타성파 속도와 콘관입저항치는 상당한 연관성을 가지고 있으며 이는 지반조사의 효율성을 증대 시킬 수 있을 것이다.
