  • 최근 지구온난화 심화와 환경재난 등으로 석유유래 플라스틱의 분해에 대한 관심이 높아지고 있다. 플라스틱의 분해를 촉진하는 산화촉진제로 ferric ion(Fe2+)을 농도별로 첨가하여 필름을 제조하였다. 대조군으로 LLDPE필름과 산화촉진제를 농도별로 첨가한 필름에 UV를 시간별로 조사하여 인장강도, 신장율과 분자량변화를 조사하였다. 수지에 ferric ion 첨가량이 많아질수록 물성저하가 컸으며, 분자량 변화도 큰 것으로 나타났다. 인장강도는 대조군에 비해 산화촉진제 첨가필름이 조사시간 100시간 후 부터는 현저하게 저하되었으며, 이러한 현상은 신장율에서도 비슷한 것으로 나타났다. 분자량은 산화촉진제 첨가에 따른 결과로 UV 조사 50시간 후 63.6%, 100시간 후에는 73.8% 분자량이 감소한 것으로 나타났다. 이상의 결과에서 플라스틱 필름에 산화촉진제인 ferric ion(Fe2+)을 첨가함에 따라서 필름의 강도와 분자량이 저하되는 결과와 김 등 등의 보고를 바탕으로 필름의 분자량이 저하되면 그만큼 필름이 분해되고 있다고 판단할 수 있을 것으로 사료되었다.

  • For the development of UFS device test system, M-PHY specifications should be matched with MIPI-standard which is analog signal protocol. In this paper, the implementation methodology and hardware structure for the M-PHY AFE (Analog Front End) Block was suggested that it can be implemented using universal components without ASIC process. The testing procedure has a jitter problem so to solve the problems we using ASIC process, normally but the ASIC process needs a lot of developing cost making the UFS device test system. In is paper, the suggestion was verified by the output signal which was compared to the MIPI-standard on the Prototype-board using universal components. The board was reduced the jitter on the condition of HS-TX and 5.824 Gbps Mode in SerDes (Serialize-deserializer). Finally, the suggestion and developed AFE block have a useful better than ASIC process on developing costs of the industrial UFS device test system.

  • Though the Platycodon grandiflorum, has a broad range of pharmacologic properties, but the mechanisms underlying these effects remain unclear. In order to profile proteins from the nodal segment, callus, root and shoot, high throughput proteome approach was executed in the present study. Two-dimensional gels stained with CBB, a total of 84 differential expressed proteins were confirmed out of 839 protein spots using image analysis by Progenesis SameSpot software. Out of total differential expressed spots, 58 differential expressed protein spots (${\geq}2-fold$) were analyzed using MASCOT search engine according to the similarity of sequences with previously characterized proteins along with the UniProt database. Out of 58 differential expressed protein, 32 protein spots were up-regulated such as ribulose-1,5-bisphosphate carboxylase, endoplasmic oxidoreductin-1, heat stress transcription factor A3, RNA pseudourine synthase 4, cysteine proteinase, GntR family transcriptional regulator, E3 xyloglucan 6-xylosyltransferase, while 26 differential protein spots were down-regulated such as L-ascorbate oxidase precursor, late embryogenesis abundant protein D-34, putative SCO1 protein, oxygen-evolving enhancer protein 3. However, the frequency distribution of identified proteins using iProClass databases, and assignment by function based on gene ontology revealed that the identified proteins from the explants were mainly associated with the nucleic acid binding (17%), transferase activity (14%) and ion binding (12%). Taken together, the protein profile may provide insight clues for better understanding the characteristics of proteins and its metabolic activities in various explants of this essential medicinal plant P. grandiflorum.

  • Platycodon grandiflorum, commonly known as Doraji in Korea, has a wide range of pharmacologic properties, such as reducing adiposity and hyperlipidemia, and antiatherosclerotic effects. However, the mechanisms underlying these effects remain unclear. In order to profile proteins from the nodal segment, callus, root and shoot, high throughput proteome approach was executed in the present study. Two dimensional gels stained with CBB, a total of 84 differential expressed proteins were confirmed out of 839 protein spots using image analysis by Progenesis SameSpot software. Out of total differential expressed spots, 58 differential expressed protein spots (${\geq}$ 2-fold) were analyzed using MASCOT search engine according to the similarity of sequences with previously characterized proteins along with the UniProt database. Out of 58 differential expressed protein, 32 protein spots were up-regulated such as ribulose-1,5-bisphosphate carboxylase, endoplasmic oxidoreductin-1, heat stress transcription factor A3, RNA pseudourine synthase 4, cysteine proteinase, GntR family transcriptional regulator, E3 xyloglucan 6-xylosyltransferase, while 26 differential protein spots were down-regulated such as L-ascorbate oxidase precursor, late embryogenesis abundant protein D-34, putative SCO1 protein, oxygen-evolving enhancer protein 3. However, frequency distribution of identified proteins using iProClass databases, and assignment by function based on gene ontology revealed that the identified proteins from the explants were mainly associated with the nucleic acid binding (17%), transferase activity (14%) and ion binding (12%). In that way, the exclusive protein profile may provide insight clues for better understanding the characteristics of proteins and metabolic activity in various explants of the economically important medicinal plant Platycodon grandiflorum.

  • Objectives: This study investigated the incidence of root dentin defects after the use of different post space preparation (PSP) drills. Materials and Methods: Seventy-two bovine incisors were selected and obtained 14-mm-long root sections. Twelve roots served as controls with no intervention (G1). The 60 root canals remaining were instrumented using the crown-down technique with the ProTaper Next system and obturated using the lateral condensation technique. Specimens were randomly distributed into 5 groups (n = 12) according to the operative steps performed: G2, root canal instrumentation and filling (I+F); G3, I+F and PSP with Gates-Glidden drills; G4, I+FI+F and PSP with Largo-Peeso reamers; G5, I+F and PSP with Exacto drill; and G6, I+F and PSP with WhitePost drill. Roots were sectioned at 3, 6, 9, and 12 mm from the apex, and digital images were captured. The presence of root dentin defects was recorded. Data were analyzed by the χ2 test, with p < 0.05 considered to indicate statistical significance. Results: Root dentin defects were observed in 39.6% of the root sections. No defects were observed in G1. G5 had significantly more cracks and craze lines than G1, G2, and G3 (p < 0.05), and more fractures than G1, G2, G3, and G4 (p < 0.05). When all root sections were analyzed together, significantly more defects were observed at the 12-mm level than at the 3-mm level (p < 0.05). Conclusions: PSP drills caused defects in the root dentin. Gates-Glidden drills caused fewer root defects than Largo-Peeso reamers and Exacto drills.

  • Die vorliegende Arbeit verfolgt zwei Ziele: zum einen sollen die Entwicklungen in der modernen zweisprachigen Lexikographie mit Ausgangssprache Deutsch skizzenhaft vorgestellt und einige Forschungsdefizite benannt werden, zum anderen sollen die Ergebnisse und Methoden der neueren Lexikographie anhand von Beispielartikeln der drei $einschl\"{a}gigen$ deutsch-koreanischen $Gro{\ss}w\"{o}rterblicher$ kontrastiert und diskutiert werden. Zuerst wird eine Typologie der zweisprachigen $W\"{o}rterb\"{u}cher$ erstellt, derzufolge es jeweils 2 aktive und 2 passive Worterblicher pro Sprachenpaar gibt. Das Aktiv-Passiv­Prinzip gilt als ein grundlegender Ausgangspunkt $f\"{u}r$ die zweisprachige Lexikographie. Eine Erweiterung der Unterscheidungskriterien scheint nicht $zweckm\"{a}{\ss}ig$ und angesichts praktischer Schwierigkeiten auch kaum realisierbar. $Pl\"{a}diert\;wird\;f\"{u}r\;eine\;st\"{a}rkere\;Ber\"{u}cksichtigung$ der Benutzungssituationen, zu denen z.B. der Grad der Sprachbeherr­schung der jeweiligen Benutzergruppe, die $m\"{o}glichen\;Benutzungsanl\"{a}sse$, der Kenntnisstand $bez\"{u}glich$ der Benutzerhinweise sowie die technische Geschicklichkeit bei der $W\"{o}rterbuch-benutzung\;etc.\;zu\;z\"{a}hlen$ sind. In makrostruktueller Hinsicht werden die Selektion und die Anordnung der Lemmata diskutiert. Bei der Lemmaauswahl $w\"{a}re\;es\;w\"{u}nschenswert$, auf der Grundlage eines Lemmavergleiches der verschiedensten Quellenworterbucher ein datenbasiertes Korpus zu erstellen. Dazu $k\"{o}nnten$ folgende Materialien ausgewertet werden: (1) einsprachige allgemeine (ad spezielle) $W\"{o}rterb\"{u}cher$ (z.B. Deutsch/Koreanisch), (2) zweisprachige allgemeine (od spezielle) Worterblicher (z.B. Deutsch-Koreanisch, Deutsch-Englisch) etc. Die $blo{\ss}e\;\"{U}bersetzung$ lediglich eines einzigen $Quellenw\"{o}rterbuches\;k\"{o}nnte$ dagegen zu $unerw\"{u}nschten\;Einseitigkeiten\;f\"{u}hren$. Was die Anordnung der Lemmata in zweisprachigen $W\"{o}rterb\"{u}chern$ betrifft, $k\"{o}nnen$ dieselben drei makrostrukturellen Typen unterschieden werden, wie in einsprachigen $W\"{o}rterb\"{u}chern$: (1) glattalphabetisch, (2) nischenalphabetisch, (3) nestalphabetisch. Unter den zu untersuchenden $W\"{o}rterb\"{u}chern$ weisen das EDK und das HDK die nischenalpha­betische Makrostruktur auf, das MDK ist dagegen nestalphabetisch angeordnet. Je nachdem, wie die Polysemiestruktur und die Mehr-Wort-Einheit kombinieren, werden die drei Arten der Mikrostruktur unterschieden: (1) die integrierte Mikrostruktur, (2) die nichtintegrierte Mikrostruktur, (3) die partiell integrierte Mikrostruktur. $W\"{a}hrend$ das EDK und das HDKeine integrierte Mikrostruktur besitzen, weist das HDK eine partiell integrierte Mikrostruktur auf. Die Artikelgestaltung durch die nichtintegrierte Mikrostruktur, die $h\"{a}ufig$ in der zweisprachigen Lexikographie angewandt wird und entsprechende Vorteile besitzt, sallte $k\"{u}nftig\;als\;Gestaltungsm\"{o}glichkeit\;st\"{a}rker$in Betracht gezogen werden. In Bezug auf die Organisation der Mikrostruktur werden vier Bauteile, das sind Lemma-, $\"{A}quivalent-$, Diskriminator- und Beispielangaben untersucht. Die $\"{U}bersetzungs\"{a}quivalente$ werden je nach dem lexikalisch-semantischen Abdeckungsgrad mit dem Lemma in drei Typen eingeteilt: (1) $Voll\"{a}quivalent,\;(2)\;Teil\"{a}quivalent,\;(3)\;Null\"{a}quivalent$. In der Mehrheit kommen die Teil- oder $Null\"{a}quivalente$ vor, weil die ausgangssprachlichen Lemmata und die zielsprachlichen $\"{A}quivalente$ in sich Polysemiestruktur aufweisen. $Informationsm\"{a}ngel$ auszugleichen ist die Funktion des Diskriminators, in dem Glosse, Markierungen und metasprachliche $Erl\"{a}uterungen$ zusammenwirken. $Verbesserungsw\"{u}rdig\;sind\;die\;g\"{a}ngigen$ deutsch-koreanischen $W\"{o}rterb\"{u}cher$ var allem im Hinblick auf die stilistischen Markierungen; die Inkongruenz des Stils zwischen den beiden verschiedenen Sprachen wird bislang zu wenig $ber\"{u}cksichtigt$ und sagar in ein und demselben $W\"{o}rterbuch$ nicht konsequent dargestellt. Trotz der relativen $Geringsch\"{a}tzung$ von Beispielangaben in der $europ\"{a}ischen$ zweisprachigen passiven Lexikographie sallte diesen in deutsch-koreanischen $W\"{o}rterb\"{u}chern$ mehr Aufmerksamkeit gewidrnet werden. Sie sind dem koreanischen Benutzer eine wichtige Hilfe, indem sie die $\"{A}quivalentenangaben\;implizite\;erg\"{a}nzen$ und Informationen $\"{u}ber$ die syntaktisch-semantische und pragmatische Kontextrestriktion bieten. $Dar\"{u}berhinaus$ stellen sie selbst interessante kulturelle, geistige und landeskundliche etc. Informationen dar. Was den Artikelaufbau betrifft, wird das Van Dale-Modell diskutiert, d.h. das kategoriell-semantisch-alphabetische Prinzip, das trotz mancher Kritikpunkte viele interessante Anregungen $f\"{u}r$ die zweisprachige Lexikographie Deutsch-Koreanisch bietet, wo z.B. noch nicht die $Pr\"{a}positionen$ in der Beispielangabe durch typographische Hervorhebung $pr\"{a}sentiert$ worden sind. Aus $Platzgr\"{u}nden$ sind hier nur wenige Beispielartikel mit substantivischen Lemmata $angef\"{u}hrt$ und analysiert worden. Um die $h\"{o}here$ Generalisierbarkeit zu erreichen, brauchen die Untersuchungs- materialien mindestens einen bestimmten Umfang. Derartige empirische Forschungen $k\"{o}nnen$ als Impulse dazu beitragen, $k\"{u}nftige\;W\"{o}rterb\"{u}cher$ im Sinne einer $Ber\"{u}cksichtigung$ neuerer lexikographischer Erkenntnisse verbessern zu helfen.
