  • In this paper, an attitude determination system(ADS) for KOMPSAT using GPS LI carrier phase measurements is considered. The baseline vector is estimated by the Exetnded Kalman Filter (EKF) which used the double differenced carrier phased measuremenmts made by three GPS receivers mounted on the spaceraft. The attitude angles of three axes of spacecrat are computed by the estimated baseline vectors, directly. The proposed ADS is verified by the simulation results.

  • An efficient method of shoot regeneration of peanut is described. In vitro shoot organogenesis from the callus of cotyledon explants of Arachis hypogaea L. was stimulated by addition of Adenine sulphate (Ads) along with 6 - benzylaminopurine (BAP) and - napthalene acetic acid (NAA). Ads (13 ${\mu}{\textrm}{m}$) had a stimulatory effect on shoot bud differentiation when combined with BAP (13 ${\mu}{\textrm}{m}$) and NAA (2 ${\mu}{\textrm}{m}$). Shoot organogenesis was markedly higher (92%) from callus induced on Ads, BAP and NAA combined media than from those formed by the individual supplementation of Ads or BAP with NAA. The shoots elongated on the media with GA$_3$ (1 ${\mu}{\textrm}{m}$). Elongated plantlets rooted with MS media containing IBA (9 ${\mu}{\textrm}{m}$).

  • The preparation of $CaSO_4$ nanoparticle by vesicles formed spontaneously in cationic OTAC and anionic ADS mixed surfactant solution whose ratio is 0.3/0.7 is investigated. Added electrolytes for preparing nanoparticles reduce vesicle size about 200-300 nm comparing with that of pure vesicle whose size is 700-800 nm by DLS. The core of vesicles has 200 nm size and acts as nanoreactors which same size of monodisperse $CaSO_4$ nanopaticles are formed. Although $CaSO_4$ particles are formed at the outer of vesicles, they are very large and amorphous. The formed particles are identified with XRD analysis after separation due to coinciding with $CaSO_4$ particles.

  • In this work, a new high frequency transmission line structure combined with defected ground structure (DGS) and artificial dielectric substrate (ADS) structure is proposed. DGS patterns give add the additional inductance to transmission lines and results in the increased characteristic impedance for a given line width. To the contrary, ADS presents increased capacitance and reduced line impedance. So both play a role in reducing the length of transmission lines commonly, but in preserving the line impedance complementarily. This means that the length of transmission lines can be reduced furtherly by DGS and ADS without a critical change of line width compared to the cases when one of DGS and ADS is used only. As examples, $35{\sim}100{\Omega}$ transmission lines having DGS and ADS are designed, fabricated, measured, and compared to the simulation results. A good agreement between the simulated and measured line impedances is presented. In addition, the physical lengths of the proposed transmission lines are only 55.4~76.9% of those of the normal microstrip lines for the same electrical lengths.

  • In this study, we conducted an experiment with the 219 undergraduates to find out the controlling effects of the verbal anchoring (low, high, non) in the nostalgia ads and the consumers' responses according to the product types (emotional/rational). The results suggest the higher the standards of the effects of the verbal anchoring are, the more favorably the preferences to the ads and the purchasing intention are formed regardless of the existence of the nostalgia. The following reveals that the controlling effects of the verbal anchoring in the nostalgia ads have differences between the purchasing intention and the preferences to the ads as to both the nostalgia familiarity and the product types. In the preferences to the ads in case that the standards of the effects of the verbal anchoring are low, the differences between familiarity group and non familiarity one are not noticeable but in the purchasing intention the differences between the low case and non of the standards of the effects of the verbal anchoring are a little more noticeable.
