Three morphospecies of the genus Uronychia, i.e. U. setigera Calkins, 1902, U. binucleata Young, 1922, and U. multicirrus Song, 1997, were collected from the coastal waters of Gumjin-ri on the East Sea and the public waterfront of Incheon on the Yellow Sea in Korea, respectively. These species are described based on live observation, protargol impregnation, silver nitrate impregnation, and their morphometrics. Diagnostic keys for these species are also provided. In addition, their small subunit ribosomal DNA sequences were compared with previously known sequences of Uronychia species. Diagnostics of three Uronychia species are as follows: U. setigera: $50-80\;{\mu}m$ long in vivo, oval-shaped, 2 macronuclear nodules (Ma), 1 spur on the left margin, 11 adoral membranelles (AM) 1, 4 AM2, 1 buccal cirrus (BC), 4 frontal cirri (FC), 3 left marginal cirri (LMC), 2 ventral cirri (VC), 5 transverse cirri (TC), 3 caudal cirri (CC), 6 dorsal kineties (DK), and approximately 23 cilia in the leftmost kinety. U. binucleata: $70-110\;{\mu}m$ long in vivo, oval to slightly rectangular shaped, 2 Ma, 1 micronucleus (Mi), 2 spurs on the posterior region, 11 AM1, 4 AM2, 1 BC, 4 FC, 3 LMC, 2 VC, 5 TC, 3 CC, 6 DK, and approximately 37 cilia in the leftmost kinety. U. multicirrus: $140-200\;{\mu}m$ long in vivo, oval to slightly rectangular shaped, ca. 7 Ma, 1 Mi, 11 AM1, 4 AM2, 1 BC, 4 FC, 3 LMC, approximately 8 VC, 5 TC, 3 CC, and 6 DK. This study presents the first record of this genus in Korea.

We investigated the amounts of radiation exposure from $^{238}U$, $^{232}Th$, and $^{40}K$ which are three major radionuclides naturally residing in soil of the Korean peninsula. The experimental results showed that the concentrations of the radionuclides were 15.77$\pm$7.27, 290.05$\pm$73.92 and 750.30$\pm$165.38 Bq/kg respectively. The absorbed dose rate based on the measured concentrations was 213.76$\pm$46.37 nGy/hr, while the spatial gamma absorbed dose rate measured in the same region was 123.90$\pm$19.18 nGy/hr. The effective dose rate was 0.26 mSv/yr, which is significantly higher than the world average effective dose rate 0.07 mSv/yr provided by the UNSCEAR.

To ascertain the effect of over-expressed maize calreticulin in tomato plant on tobamovirus movement in addition to validating potentiality of the gene (ZmCRT) as a means for the virus-resistance resource, four ZmCRT-expressing homozygous lines were generated from the T0 plants as using an Agrobacterium-mediated transformation, nucleic acid analyses, and a conventional breeding method. Of them, a line was subjected to the bioassay for tolerances to tobacco mosaic virus-U1 (TMV-U1) and tomato mosaic virus (ToMV) followed by RT-PCR and a chlorophyll fluorescence quenching analyses. Both transgenic plants transcribing ZmCRT and wild-type plants showed no symptom by 20 days after viruses inoculation, however the photosystem II quantum yield parameter measured from the upper leaves of ToMV-inoculated plants revealed that ZmCRT transgenic plants have higher photosynthetic ability than wild-type ones at that time, which indirectly implies that over-expressed ZmCRT product acts as a barrier to the cell-to-cell and/or systemic movement of ToMV. Moreover, ZmCRT transgenic plants showed remarkably longer shoot length than wild-type ones in 40 days after TMV-U1 or ToMV inoculation each, which might be resulted from higher photosynthetic ability during the phase not yet showing any external symptoms. Collectively, over-expressed ZmCRT protein in tomato plants is able to interrupt the systemic movement of infected TMV-U1 and ToMV even though not perfect.

These experiments were conducted to purify the glucoamylase produced by Rhizopus oryzae. Two forms of glucoamylase (GI and GII) from Phizopus oryzae were purified by $(NH_2)_2SO_4$ fractionation, acetone fractionation and successive column chromatography on DEAE-cellulose and CM-cellulose. The specific activities of GI and GII toward soluble starch were 157.6 U/㎎. protein (37.5 fold of crude extract), and 164.7 U/㎎. protein (39.2 fold of curde extract), respectively, and the yields of them were 4.3% and 3.8%, respectively. The two purified enzymes have shown a single band by polyacrylamide disc gel electrophoresis and SDS-polyacrylamide gel electrophoresis. The protein bands of their electrophoresis gel were revealed to have glucoamylase activity by iodine staining and were proved to be glycoprotein by periodic acid Schiff's staining.

연구개는 그 주위조직과 더불어 생리적 기능에 있어 음성, 연하, 및 호흡 등에 중요한 역할을 한다. 종양등의 이유로 인한 연구개의 외과적 절제는 그 해부학적 크기와 모양의 영구적인 변화로 인해 여러기능의 상실을 초래한다. 이에 따른 결함은 과도한 비음, 연하중 음식물이나 유동물의 비관으로의 누출 등을 들 수 있다. 연구개와 그 주위조직의 생리적인 기능의 숙지 및 이를 응용한 보철물(Palatopharyngeal Obturator)의 적절한 제작은 이러한 기능적 결함을 수복하는데 이용되어진다. 본 증례에서는 종양으로 인해 연구개를 절제한 환자의 보철적 수복에 있어, 구강내 온도에 따라 그 형상이 변화하는 인상재를 이용하여, 측-후 인두벽의 운동을 기능적으로 인기하는 방법을 이용하였다. 이러한 방법으로 제작된 보철물은 종양으로 인한 연구개의 절제 후 생리적인 기능의 장애를, 올바른 Palatopharyngeal 폐쇠를 유도함으로써 음질의 향상, 연하등의 기능을 회복시키는데 큰 도움이 될 수 있음을 보여준다.

In this paper, we describe 72-year-old female patient without evidence of malignant disease presented with significantly elevated serum carbohydrate antigen (CA) 19-9 levels by respiratory infections. She was diagnosed with respiratory infections due to Mycobacterium avium complex and Pseudomonas aeruginosa. The serum CA 19-9 levels remarkably increased (1,453-5,300 U/mL; reference range, <37 U/mL) by respiratory infection and abruptly decreased (357-534 U/mL) whenever infection was controlled by specific treatments. This case suggests that serum CA 19-9 levels may be used as a diagnostic marker to indicate new or resistant infections to previous antibiotics in chronic lung diseases without significant changes in chest X-ray findings.

In dieser Arbeit wird versucht, einen weiteren theoretischen Rahmen $f\"{u}r$ die Farbensymbole(Rot, Gelb und Grun) in der deutschen, englischen und korearischen Sprache, vor allem in Idiomatik weiterzuentwickeln. Rot und Grun sind in diesen Sprachen reichlicher als Gelb vertreten. Die symbolische Bedeutung von Rot ist besonders ambivalent Es ist die Farbe der Gesundheit, aber auch die Farbe des Blutes, Krieges und Todes. Rot ist in den untersuchten Sprachen als 'sehr', 'gut', 'gesund' oder 'schlecht' belegt Rot zeigt aber einzelsprachliche Eigenschaften. Im Koreanischen ist Rot syrnbollisch mit 'Frau', im Englischen mit $'B\"{u}rokratismus'$ verbunden.. Gelb hat auch $widerspr\"{u}chliche$ Symbolbedeutung .Es ist die Farbe der $Fr\'{u}hlingsblumen$, der Sonne und des Lichtes. Aber Gelb kann die Farbe von 'Neid, Eifersucht' oder 'feige, schlecht' sein. Grun ist die wichtigste Farbe der Natur. So ist diese Farbe symbolisch mit 'gut', 'unreif, 'sehr, viel', 'Wachstum und Gedeihen' assozziert. Durch Vergleich und Analyse der Farbensymbole in diesen drei Sprachen und durch Resultat der Antwort auf Fragenbogen an denen 99 Deutschen, 100 Amerikaner und 101 Koreaner teilnahmen, zeichnen sich folgende Ergebnisse ab. Sprachsymbole von dieser Farbe hat auf die Farbenwahrnehmungen von diesen Leuten nicht direkte $Einfl\"{u}sse{\;} ausge\"{u}bt$. Rot assoziert in 89 Koreanern und 5 Amerikanern 'Leidenschaft': Gelb in 52 Amerikanem, 47 Deutschen und 38 Koreanern $'W\"{a}rme'$: Grun in 33 Amerikanern, '37 Deutschen und 11 Koreanern 'Frieden'. Im Englischen und Deutschen zeigt sich die Assoziation von Gelb mit 'Neid, Eifersucht', was mit kulturellen Vorstellungen $\"{u}bereinstimmt$. 38 Deutsche und 4 Amerikaner geben $f\"{u}r$ Gelb die Symbolbedeutung 'Neid' an. Hier bin ich mit sprachlichem Determinismus von Wharf-Hypothese einverstanden: Verschiroene Sprachgemeinschaften erfassen die Wirklichkeit in ganz verschiedener Weise. Sprachsymbol und Kul­tursymbol scheinen an die Farbenwahrnehmungen von untersuchten Leuten $anzukn\"{u}pfen$.
