To study effective dossage and administration route for scaling, ketamine HCl/propionyl promazine HCl(ketamine) combination and tiletamine HCl/zolazepam HCl(zoletil) were administered in one hundred six dogs. The dogs were toy poodle, Yorkshire Terrier, Pekingese and Chihuahua. Scaling and polishing time, possible treatment time after the first injection of anesthetics, the number of anethesia added, presence of tongue movement during anesthesia, the presence of swaying sign during recovery and respiration were evaluated. The possible treatment time after the first Injection of anesthetic in toy poodle were 26.3${\pm}$3.0 minutes with intravenous(IM) treatment of ketamine 10mg/kg, and 21.4${\pm}$6.6 minutes with intramuscula(IM) treatment of zoletil 8mg/kg, In Yorkshire Terrier were 19.51: 1.7 minutes with IV treatment of ketamine 10mg/kg. 19.0${\pm}$5.2 minutes IM and 20.8${\pm}$6.1 minutes with IM treatment of zoletil 5mg/kg,24.8${\pm}$3,5 minutes with IM treatment of zoletil 8mg/kg. In pekingese were 27.5${\pm}$2.1 minutes with IM treatment of ketamine 10mg/kg,28.0${\pm}$4.2 minutes with IM treatment of zoletil 8mg/kg. In Chihuahua were 19.5${\pm}$1.9 minutes with IV treatment of ketamine 7mg/kg, 17.5${\pm}$1.7 minutes with IM treatment of ketamine 10mg/kg and 20.3${\pm}$3.8 minutes with IM treatment of zoletil 5mg/kg, 21.2${\pm}$5.5 minutes with IM treatment of zoletil 8mg/kg. Swaying sign was observed in all group during recovery time, espically, in toy poodle and Yorkshire Terrier which administered zoletil 8mg/kg IM showed more severe swaying sign. The present results suggested that injection of zoletil 8mg/kg IM might be relatively effective for scaling in Chihuahua Within 20 minutes treatment for scaling in Yorkshire Terrier and Chihuahua, IM treatment of ketamine 7 to 10mg/kg is recommended.

IM(Instant Messenger)은 현재 가장 각광받고 있는 개인 커뮤니케이션 도구이다. 이는 개인에게는 전자우편을 대신할 도구로 기업에게는 사용자 확보의 도구이자 무한한 잠재력을 가진 도구로 평가받고 있다. 하지만, IM은 보안상 여러 문제점을 내포하고 있다. 전송 메시지에 대한 총격에 안전하지 못하다는 점을 비롯하여 여러 취약점들이 보고되고 있고, 이를 이용한 해킹 도구들이 개발된 상태이다. 다시 말해, IM을 통해 주고 받는 메시지는 누구든지 엿볼 수 있으며 조작 가능하다는 것이다. 이는 기업의 전략적 도구로의 발전에 큰 걸림돌로 작용하며 개인의 프라이버시에 대한 심각한 문제를 낳을 수 있다. IETF의 IMPP WG(Working Group)에서는 IM간의 상호 연통을 위한 표준을 준비하고 있으나 가장 많은 IM 사용자를 확보하고 있는 AOL(American On-Line)의 불참으로 관련 표준 제정의 진행이 원만하지 않은 상태이며 전송되는 데이터의 형식에 관한 논의만이 주로 이루어질 뿐 전체적인 보안서비스에 대한 논의는 미비한 상태이다. 본 논문에서는 이러한 IM의 취약점과 보안상의 문제를 해결하여 안전한 단문 전송 시스템(SIMS ; Secure Instant Messaging System)을 설계 및 구현하였다.

This study investigated relationship between preservice kindergarten teachers' cognitive strategies and self-determination motivation types. Cognitive strategies were measured by 3 variables surface, deep, and metacognitive strategies; motivation for self-determination was measured by 7 variables; intrinsic motivation(IM) to know, IM to accomplish, IM to experience stimulation, external regulation, introjected regulation, identified regulation, and amotivation. The Motivated Strategies for Learning Questionnaire(Pintirch & DeGroot, 1990) and the Academic Motivation Scale(Vallerand et al., 1992, 1993) were administered to 82 subjects. Data were analyzed by Pearson's correlation, multiple regression analysis, and canonical correlation analysis. Finding were a positive correlation between IM to know and IM to accomplish. IM to accomplish positively predicted surface, deep, and metacognitive strategies, and identified regulation positively predicted deep cognitive strategy. Amotivation negatively predicted deep and metacognitive strategies.

An integrated magnetic (IM) transformer is proposed for a phase shifted full bridge (PSFB) converter with zero voltage switching (ZVS). In a proposed IM transformer, the transformer is located on the center leg of E-core and the output inductor is wound on two outer legs with air gap. The proposed IM transformer is analyzed by using the magnetic capacitor model. For reducing the core size, EE core is redesigned. The proposed IM transformer is experimentally verified on a 1.2 kW prototype converter. The converter efficiency with the proposed IM transformer is about 93 % at full load and its volume size can be reduced. It can be expected that the power density can be largely increased with the proposed IM transformer.

Herein we report multiple ion mobility (IM) peaks in electrospray ionization IM mass spectrometry (ESI-IM-MS) produced by glutamine residue in peptide. The mobility features of 147 peptides were investigated using ESI-IM-MS combined with liquid chromatography. Of these peptides, 66 presented multiple IM peaks, and analysis of their sequence using collision induced dissociation (CID) revealed that glutamine (Gln), as well as proline (Pro), plays a critical role in generating multiple IM peaks. Mutant-based investigations using Gln-containing peptides indicate that the side chain of Gln promotes intermolecular interactions, inducing multiple structures of the peptide ions in the gas phase. Consequently, the present study demonstrates that the distinct ion mobility signatures identified herein can potentially be used to characterize glutamine-containing peptide ions.

The purpose of this study was to analyze chemical water quality, fish trophic guilds, tolerance indicators, and fish community conditions in the Gap Stream and to compare the stream conditions between the unimpacted site and impacted site. This study was conducted in the physically stable season (May 2008) to minimize physical impacts such as flow and hydrological disturbance, and applied the study in the Gap Stream with two sites of unimpacted upstream site (Unim-S), mainly surrounded by forested area and impacted site (Im-S), influenced by the wastewater disposal plants and industrial complex in the urban region. Chemical data analysis showed that the degree of organic matter pollution, based on BOD, and COD, was $2{\sim}3$ fold greater in the Im-S than the Unim-S, and that TP, as eutrophication indicators, was 4.7 fold greater in the Im-S. Also, $NH_3-N$ was in 8.2 fold greater in the Im-S ($6.25\;mg\;L^{-1}$) than the Unim-S ($0.76\;mg\;L^{-1}$), indicating a massive influence of wastewater from the disposal plant. Similar results were found in other chemical parameters. Thus, chemical impacts in the Im-S were evident, compared to the unimpacted site. Evaluations of tolerant indicator species indicated that sensitive species were dominant in the Unim-S (23.9%) and tolerant species were dominant (97.8%) in the Im-S. Condition factor (CF) was averaged 0.95 ($0.68{\sim}1.18$) in the Unim-S and 1.08 ($0.93{\sim}1.22$) in the Im-S. Fish community in the Unim-S and Im-S was categorized as Zacco-community and Hemibarbus-community, respectively, and the community diversity index (H') was significantly (p<0.05) higher in the Unim-S (0.810) than the Im-S (0.466). Overall, our results suggest that the comparison approach of various chemical and ecological indicators provide important information in identifying multiple stressors in the stream ecosystems.

Nonwoven fabrics have been widely used in various fields that include household, industrial, agricultural, medical goods, especially in the automobile industry. In this study, eco-friendly fiber materials were developed and investigated as a substitute material for polyester fibers in nonwovens. To make plant fiber bundles, stems of Indian mallow (IM), and Kuzu vine (KV) were retted; in addition, the non-cellulose component was partially removed. Plant fiber bundles and polyester fibers (P) were blended and needle punched to produce nonwovens. Five kinds of nonwovens were manufactured: P100 (Polyester 100%), IM10 (IM 10% and Polyester 90%), IM20 (IM 20% and Polyester 80%), KV10 (KV 10% and Polyester 90%), and KV20 (KV 20% and Polyester 80%). The color values, surface appearance, tensile strength, elongation, tear strength, abrasion strength, flexstiffness, moisture regain, water or oil absorbency, and static electricity of manufactured nonwovens are investigated. As the blended ratios of IM or KV increased, the brightness of nonwovens decreased compared to that of polyester 100%. Tensile strength, tear strength, abrasion strength, and flexstiffness of IM10 as well as KV10 were higher than those of P100, IM20, and KV20, resulting from the influence of the structure and properties of nonwoven fibers. Moisture regain and water or oil absorbency increased, while static electricity decreased in proportion to the amount of plant fibers. IM or KV and polyester blended nonwovens showed improved properties over P100 that could be substituted for P100 as a novel material for textiles.

Die Pluralformen (-(e), -( e)n, -'e, -'er, -s) sind durch die Flexionsklassen detenniniert. Basierend auf Genus und prosodischen Eigenschaften werden Plural­klassen unterschieden. Unter den Substantiven mit konsonantischem Wortauslaut wahlen die Feminina den (e)n-Plural, die Maskulina und Neutra im Allgemeinen aber den (e)-Plural. Es ist also anzunehmen, dass es fur jede Flexionsklasse eine vorhersagbare regulare Pluralbildung gibt Die Bildungen mit Umlaut (-'(e)-PI. und -'er-Pl) unterscheiden sich durch die deutlicheren, $verst\"{a}rkten$ Pl.-Markierungen vom einfachen Typ. Im Hinblick auf die $Regularit\"{a]ten$ im Pluralsystem ist festzustellen, dass die Numerusmarkierung bei den Feminina konsequenter ist als bei den Maskulina und Neutra. Im Weiteren spielt bei der Beschreibung der Pluralbildung der Begriff Markiertheit eine $gro{\ss}e$ Rolle. $Anschlie{\ss}end$ wird gezeigt, dass das Pluralsystem nach $Beschr\"{a}nkungen$ aufgebaut ist, die silbenphonologischer und morphologischer Natur sind. Im Rahmen der $Optim\"{a}litatstheorie$ werden die Pluralanalysen von Wegener und Wunderlich vorgestellt. Dabei werden die verschiedenartigen Pluralbildungen mithilfe zusammengestellter Begriffsinstrumentarien, die $f\"{u}r$ die Auswahl einer guten Pluralform ausreichen, vereinfacht dargestellt. Damit bestatigt sich das Plural system im Deutschen als nach klaren Prinzipien geordnet, wenn es auch komplex ist. $Schlie{\ss}lich$ wird der s-Plural als markierte Pluralform $ausf\"{u}hrlich$ gezeigt. Die These, der s-Plural sei der Defaultwert und einzige $regul\"{a}re$ Plural im Deutschen, gilt nur mit $Einschr\"{a}nkung$, da dieser Typ $haupts\"{a}chlich$ in bestimmten Bereichen des Wortschatzes auftritt. Es $w\"{a}re$ also angebracht, den s-Plural als 'unmarkierte Pluralform im markierten Bereich' anzusehen.
