  • GEO-KOMPSAT-2 which is under development by KARI to be launched in 2018 is expected to be injected into its orbit through the standard GTO(Geostationary Transfer Orbit) or SSTO(Supersynchronous Transfer Orbit). While the standard GTO mission has been applied for the most of the geostationary satellites, the SSTO mission is rare case and significantly different from the standard GTO mission in technical point of view. This paper lists the operational constraints to be applied for GEO-KOMPSAT-2 SSTO mission, and introduces a preliminary LAE burn plan for GEO-KOMPSAT-2 mission. In order to evaluate the developed plan, a simulation study has been performed considering ground station visibility.

  • This study is about developing a transit assignment model on railway network. Current transit assignment models are mainly focused on road or urban transportation so that these models, for example, transit assignment model based on optimal strategy generates unrealistic transit assignment. Especially, since the advent of KTX, more passengers are using the transfer route containing KTX but most transit assignment models have a shortcoming that transfer is not considered or is overestimated. We present a new stochastic transit assignment model based on LOGIT considering transfer resistance.

  • A new genus and two new species of Bathynellacea are described from California in USA. Califobathynella, a new genus, belongs to the subfamily Leptobathynellinae, and is closely related to the genera Parvulobathynella and Leptobathynella but differs from them with respect to labrum, maxillule, maxilla, and male thoracopod VIII. Based on the detailed structure of mouthparts, the phylogenetic relationship of three genera are discussed. The phlogenetic age of the stem species of three genera are estimated at the late Jurassic, based on their phylogenetic relationship and distribution pattern. Two new species, C. noodti and C. teucherti differ from each other in the structure of labrum.

  • In this paper we represent a new species, Cteniobathynella ahnerti sp. nov., from South America. The new species is characterized by the heterodont teeth on free margin of labrum, the spine row of the mandible consisting of four thick spines, the presence of two setae on outer distal margin of distal segment of maxillule, the prehensile nature of maxilla and the oblique arrangement of two spines on sympod and the presence of a median spine on the endopod of the uropod.

  • Adult type of osteochondritis dissecans of elbow is very rare condition. We describe a case of a osteochondritis dissecans of capitellum in 51-year-old male patient. We performed arthroscopy procedure for removal of loose osteochondral fragments. After I year follow-up, the patient gained good result.

  • Metoprolol (MT) is one kinds of adrenergic beta-blockers. Its (S)-enantiomer is known to be more active than the (R). Recently. the x-ray structure of beta-blocker. (S)-propranolol (a-naphthyl analogue), complexed in a mould fungal cellulase. Cel7A. was reported and the (R)-form did not build any complex. And in our previous study the conformation and stability of MT in carboxymethylated beta-cyclodextrin (BCD) complex was determined by NMR. HPLC, UV and electrophoresis measurement. (omitted)

  • The chromosome numbers of two sea anemones, Anthopleura midori and A. kurogane, were determined to be 2n=18 in both by the air-drying method. The chromosomes of A, midori are all telocentric, while the first pair of chromosomes of A. kurogane is subtelocentric and the remainders are all telocentric.
