  • Catinia plana Bocquet and Stock, the type genus and species of the family Catiniidae, which has been known incompletely is redescribed on the basis of type material. Structure of appendages, especially those of mandible and maxilla, are reinterpreted. In addition, two new species of Myzomolgus associated respectively with the sipunculids Sipunculus nudus Linnaeus and Siphonosoma cumanense (Keferstein) are described from Korean waters. A comparison of already known species of Myzomolgus and two new species of the same genus resulted in a conclusion that members of this genus possess homogeneous traits and the genus is a well established taxon. A key to distinguish five genera of the Catiniidae is also provided.

  • The vinyl-shielded rearing chamber was controlled by automatic electric heater to maintain relatively constant temperature and under this condition, it took 13 to 14 days from egg to adult and 8 days for their preoviposition. The pupal weight was not varied with the advance of generation, whereas was greatly effected by temperature changes. Since only $60\%$ of the pupae was able to classify the sex by pupal weight, a mechanical device will be needed for the further sexing.

  • In 1998, bacterial shot hole of peach (Prunus persica) and Japanese plum(Prunus salicina) was found in Naju and Milyang. Five isolates of bacteria isolates from the diseased leaves and fruits of peach and Japanese plum were classified into genus Erwinia and Xanthomonas on diagnostic characteristics. Of five isolates, two were identified as X. campestris pv. pruni, three as E. nigrifluens. E.nigrifluens is the first description of bacteria which causes the disease on peach and Japanese plum in Korea. the symptoms caused by E. nigrifluens were hardly distinguished from those caused by X. campestris pv. pruni. In addition, it was observed that two pathogenic bacteria were isolated from most of naturally infected plants at the same time. from the reason mentioned above, we proposed to use a single common name \"bacterial shot hole of peach and Japanese plum\" for the both bacterial diseases, hereafter.

  • 본 연구는 중국의 3개지역 (Hebei, Shaanxi, Shanghai)에서 한 자녀가족정책이 둘째 및 셋째 아이의 출산에 미치는 영향을 헤져드(Hazard) 모델을 이용하여 분석하고 있다. 특히, 그 정책효과의 도시와 농촌간의 격차, 현재자녀의 성구조에 따른 격차의 연구에 중점을 두고 있다. 연구자료는 1985년에 완료된 제 1단계 중국의 출산력 심층조사 (In-Depth Fertility Survey in China)를 이용하였다. 이 분석은 해져드 모델에서 각 시점의 한 자녀정책 전인지 후인지를 나타내는 시간에 따른 변동변수(time-varying variable)를 설명변수중의 하나로 포함시키고 그와 더불어 그 변수와 도시/농촌 주거여부를 나타내는 변수와의 혼합변수 (Interactive term) 및 현존자녀의 성구조와의 혼합변수를 포함하므로써 가능하게 된다. 또한, 자녀의 사망력이 차후 출산력에 미치는 영향을 비슷한 방법으로 분석하였다. 연구결과로는 첫째, 둘째 및 셋째 아이를 출산할 확률에 있어서 도시와 농촌격차가 한 자녀정책 실시 이후 더욱 커졌다는 사실이다. 이러한 결과는 부모가 생각하는 자녀의 가치가 도시에서 더 많이 저하했음을 제시하거나 정부의 한 자녀정책이 도시에서 더욱더 엄격히 집행되고 있음을 시사하고 있다. 둘째, Hebei와 Shanghai에서는 남아가 없는 부부가 남아를 가진 부부보다 둘째 또는 셋째아이를 가질 확률이 훨씬 높게 나타났다. 한편, Shanghai에서는 한 자녀정책 이후 둘째아이의 출산률이 첫째아이의 성에 관계없이 매우 낮았다. 이는 전통적으로 내려오는 남아선호 성향이 아직 농촌지역에서는 강하게 영향을 미치고 있지만 도시지역에서는 강력한 정책집행이 이를 억누르고 있음을 시사하고 있다. 하지만 Shanghai에서도 첫째아이가 사망한 경우 그 아이가 남아였으면 죽은아이가 여아이였을 경우보다 둘째아이의 출산이 훨씬 더 빠르게 나타나고 있음을 볼 때 도시에서도 여전히 남아선호 성향이 잠재하고 있음을 간접적으로 보여주고 있다.

  • Novel baculovirus vector systems recombined with coding genes of polyhedron promoter, vesicular stomatitis virus G (VSVG), polyA, cytomegalovirus (CMV) promoter, enhanced green fluorescent protein (EGFP), and protein transduction domain (PTD) were constructed. These recombinant baculovirus vector systems were applied into human foreskin fibroblast cells and compared the effects of gene transfer and gene expression of these recombinant baculovirus vector systems with control vector system. From this study, it showed that these novel recombinant baculovirus vector systems were superior efficacy to control vector system in view of gene transfer and gene expression.

Kontrastive Untersuchung zu deutschen und koreanischen Phraseologismen - unter besonderer Berucksichtigung ihrer Gemeinsamkeiten und Verschiedenheiten - (성구어의 대비연구 - 독일어와 한국어 성구어의 공통성과 상이성을 중심으로 -)

  • In der vorliegenden Arbeit wird versucht, sowohl die Gemeinsamkeiten bzw. $\"{A}hnlichkeiten$ als auch Verschiedenheiten der deutschen und koreanischen Phrasologismen festzustellen, wobei die interkultuellen Unterschiede der beiden Sprachgemeinschaften besonders $ber\"{u}cksichtigt$ werden sollen. Dabei wird von den deutschen Phraseologismen ausgegengen und es werden die Entspechungen in den koreanischen gesucht. Die $Entsprechungsm\"{o}glickeiten$ lassen sich wie folgl feststellen: 1) Gemeinsamkeiten von deutschen und koreanischen Phraseologismen (Auge um Auge, Zahn um Zahn; Augen zudrucken) 2) Entspechung von deutschen Phrasologismen und koreanischen Einzellexemen (Grund und Boden; Knall und Fall) 3) Interpretation deutscher Phraseologismen in koreanische Sprache (in Fleisch un Blut $\"{u}bergehen$; eine $H\"{a}nde$ $w\"{a}scht$ die andere) $\"{A}hnlichkeiten$ bzw. Gemeinsamkeiten bestehen vor allem in den Phraseologismen, deren gemeinsame Quelle auf die $\"{U}bernahme$ desselben Kulturgut wie die Antike, die Bibel und die Weltliteratur $zur\"{u}ckzuf\"{u}hren$ ist. Die $\"{A}hnlichkeiten$ zeigen sich auch bei den vielen somatischen Phraseologismen der beiden Sprachen, da manche somatischen Bezeichnungen die gleichen Symbolwerte haben. Hingegen beruhen Verschiedenheiten vorwiegend auf den interkulturellen Unterschieden der beiden Sprachgemeinschaften, die sich historisch­gesellschaftlich unterschiedlich entwickeln und keine Gemeinsamkeiten in Sitten und $Volksbr\"{a}uchen$ haben. Insbesonders bei den phraseologischen Vergleichen kommen viele Tierbezeichnungen als Einheit der Phraseologismen vor, die sich einander stark unterscheiden (dt. arbeiten wie ein Pferd $\to$ kr. arbeiten wie ein Rind; dt. wie Hund und Katze leben $\to$ kr. wie Hund und Affe leben). Die Zwillingsformeln der deutschen Phraseolgismen sind im Koreanischen als Einzellexem oder durch die Redupulikation $auszudr\"{u}cken$(Haus und Hof; klipp und klar; mit $H\"{a}ngen$ und $W\"{u}rgen$). Einige Redewendungen und $Sprichw\"{o}rter$ im Deutschen entsprechen den aus 4-Buchstaben bestehenden Redewendungen im Koreanischen, die aus der chinesischen Kultur stammen(viele Hunde sind des Hasen rod; Gelegenheit macht Diebe). Es sind naturlich manche Redewendungen bzw. $Sprichw\"{o}rter$, deren unterschiedliche Ausdrucksweisen auf die interkulturellen Verschiedenheiten $zur\"{u}ckzuf\"{u}hren$ sind (die $W\"{a}nde$ haben Ohren; der Apfel $f\"{a}llt$ nicht weit vom Stamm)
