  • Rotavirus infection is the leading cause of severe diarrhea disease in infants and young children worldwide. Rotavirus infects every child at least once by her/his $5^{th}$ birthday. It has been known that single episode of rotavirus infection can protect or alleviate subsequent illness caused by both homotypic and heterotypic rotaviruses. There are two currently licensed rotavirus vaccines. One is human-bovine rotavirus reassortant pentavalent vaccine ($RotaTeq^{TM}$), which contains five reassortant rotavirus (expressing protein G1, G2, G3, G4 and P[8]) and was licensed in Korea for use among infants in 2007. Another is live-attenuated human rotavirus vaccine ($Rotarix^{TM}$) derived from 89-12 strain which represents the most common of the human rotavirus VP7(G1) and VP4(P[8]) antigens. $Rotarix^{TM}$ was licensed in Korea in 2008. Both live oral rotavirus vaccines are efficacious in preventing severe rotavirus gastroenteritis.

  • We predict agigantic perpendicular magnetocrystalline anisotropy (MCA) in Fe (001) capped by 5d transition metal (TM) overlayers by using first principles calculations. Analysis of atom-by-atom contribution to MCA reveals that gigantic MCA as large as 11 meV/TM originates not from Fe atoms but from the 5d TMs through the strong spin-orbit coupling. More specifically, it is the hybridization between TM and Fe d orbitals that also induces non-negligible magnetic moments in TM. Furthermore, spin-channel decompositions of MCA matrix with and without the presence of Fe substrate identify the electronic origin of the perpendicular MCA that the down-down channel contribution plays the most crucial role for the sign changes of MCA of TM overlayers upon the hybridization with Fe-3d.

  • We report the salient features of the magnetic properties of amorphous TM70Cr5Si10B15(TM=Fe, Co, Ni) alloys. The temperature dependence of magnetization for amorphous ribbons were measured by a SQUID and a VSM from 5 K to 700 K under an external field of 10 kOe. Except TM70Cr5Si10B15 that shows a paramagnetic behaviour, both Fe and Co based amorphous alloys show a typical ferromagnetic thermo-magnetization curves. For these two ferromagnetic alloys, the saturation magnetization in the temperature range from 5 K to about 0.4 Tc can be descrived by the Bloch relation, Ms (T)=Ms(0) [1-BT3/2-CT5/2]. The spin wave stiffness constants and the range of exchange interaction were analyzed from the magnetization behaviour. The variation of the magnetic properties are discussed and compared with the composition of the alloys.

  • A new algorithm for the rate control of videos considering the sensitivity of the human visual system is presented. The method adopts the three-step structure of MPEG2 TM5 rate control, and a new measure of macroblock activity based on spatio-temporal sensitivity is introduced for the adaptive quantization. Experimental results show that the spatio-temporal activity measure outperforms the spatial activity of TM5 in picture quality.

  • Susceptibility or resistance of the Bordetella bronchiseptica was determined by using the broth microdilution method. Each Bordetella bronchiseptica was tested fur sutraceptluility with 7 different antimicrobial agents.4 high prevalence of resistance (greater than 80 %) was found when Bordetella bronchiseptica was tested with amikacin (AK), ciprofloxacin ILrJl gentamlcin IGAgf, kanamycin (Kbf) and tobramycin (TM). However, the Bordetella bronchiseptica were sensitive to chloramphenicol (CP) and tetracycline (TC). Three different combination of drug resistance were observed : AM-CF-GM-TM (1 strain), AM-CF-GM- KM-TM (45 strains), and AM-CF-GM-KM-TM-CP (3 strains). The MICs against Bordetella bronchiseptica were 0.13 to >2.00 for TC, 4 to >648 for CP, 8 to >128 for CF 16 to >256 for GM, 16 to >256 for TM, 32 to >256 for KM and 64 to 256 for AM.

  • $Dy^{3+}-(or Tm^{3+}-)$ doped $Ga_2O_3 \;and\; ZnGa_2O_4$ phosphors were prepared using the solid state reaction method to investigate their photoluminescent characteristics. Under 254 nm excitation, $Dy^{3+}-doped Ga2_O_3$ exhibited two emission bands of 460~505nm and 570~600nm. On the other hand, $Dy^{3+}-(or Tm^{3+}-)$ doped $ZnGa_2O_4 $phosphors exhibited a broad-band emission extending from 330 nm to 610 nm, peaking at about 430 nm(or 370 nm). In this study, an emission peak shift of nealy 50 nm towards longer wavelength region was observed with $Dy^{3+}$ doping in the $ZnGa_2O_4 $.

  • Purpose: This review aimed to evaluate the effectiveness of telemonitoring (TM) in the management of children and adolescents with asthma. Methods: We searched Ovid-MEDLINE, Ovid-EMBASE, CENTRAL (Cochrane Central Register of Controlled Trials), CINAHL (Cumulative Index to Nursing and Allied Health Literature), and 5 domestic databases to identify randomized controlled trials (RCTs) published through December 2017. Two reviewers independently selected relevant studies, assessed methodological quality and extracted data. We performed a meta-analysis of TM versus usual care and summarized the intervention characteristics of included studies. Results: Of the 3,095 articles identified, 8 RCTs (9 articles) were included in this review. The type of TM intervention of included studies was varying across studies (transmitted data, transmission frequency, data review, etc.). The pooled asthma control score was not significantly different between TM and usual care (standardized mean difference 0.04, 95% confidence interval (CI) -0.20~0.28). Another pooled analysis demonstrated no statistically significant difference in asthma exacerbation between TM and usual care (odds ratio 0.95, 95% CI 0.43~2.09). Overall, the pooled results from these studies revealed that TM did not lead to clinically significant improvements in health outcomes, but some studies in our analysis suggested that TM increased patient medication adherence and intervention adherence. Conclusion: The current evidence base does not demonstrate any differences between TM intervention and usual care, but TM intervention might be considered a promising strategy for the delivery of self-management support for children and adolescents with asthma. Further well-designed studies are needed to assess the effects on clinical outcomes.

  • Statement of problem: For the long-term success of removable partial dentures, the bonding between metal framework and denture base resin is one of the important factors. To improve bonding between those, macro-mechanical retentive form that is included metal framework design has been generally used. However it has been known that sealing at the interface between metal framework and denture base resin is very weak, because this method uses mechanical bonding. Purpose: Many studies has been made to find a simple method which induces chemical bond, now various bonding system is applied to clinic. In this experiment, shear bond strengths of heat-cured denture base resin to the surface-treated Co-Cr alloy were measured before and after thermocycling. Chemically treated groups with Alloy $Primer^{TM}$, Super-Bond $C&B^{TM}$, and tribochemically treated group with $Rocatec^{TM}$ system were compared to the beadtreated control group. The data were analyzed with two-way ANOVA. Result: 1. Shear bond strength of bead-treated group is highest, and Alloy $Primer^{TM}$ treated group, Super-Bond $C&B^{TM}$ treated group, RocatecTM system treated group were followed. Statistically significant differences were found in each treated group(p<0.05). 2. Surface treatment and thermocycling affected shear bond strength(p<0.05), however there was no interaction between two factors(p>0.05). 3. Shear bond strengths of bead-treated group and Alloy $Primer^{TM}$ treated group showed no statistically significant difference before and after thermocycling(p>0.05), and those of Super-Bond $C&B^{TM}$ treated group and $Rocatec^{TM}$ system treated group showed statistically significant difference after thermocycling(p<0.05).
