  • 본 논문에서는 J2ME상에서 JSR-184를 이용한 모바일 3D 엔진을 설계 및 구현하였다. 기존에는 모바일 표준 3D 그래픽 API(C언어 기반)인 OpenGL-ES를 사용하여 모바일 3D 엔진을 제작해, 핸드폰에 애플리케이션을 작동시켰으나, 저수준(Low-Level)의 다양한 기능만 제공함으로써, 다양한 콘텐츠제작 및 호환성에 제약이 많았다. 이에 OpenGL-ES보다 더욱더 다양한 고수준(High-Level)의 API를 제공하면서도 GSM 폰을 중심으로 J2ME상에서 자바환경에 최적화된 모바일표준 3D 표준 API(Java언어 기반)인 JSR-184로 모바일 3D 엔진을 제작하고, 스킨드 메시(Skinned Mesh) 형태를 가지는 모델의 처리속도를 향상시키는 방법을 제시한다.

  • The low density lipoprotein receptor-related protein 5 (LRP5) highly expressed in many tissues, including hepatocytes and pancreatic beta cells, can bind to apolipoprotein E. To evaluate in vivo roles of LRP5, we generated LRP5-deficient mice. LRP5 genomic DNA was isolated from TT2 embryonic stem (ES) cells. Targeting vector was constructed to disrupt an exon 18 of the mouse LRP5 gene and transfected into ES cells. Three homologous recombinants at LRP5 locus were identified from 178 G418-resistant clones. Chimeric males generated by morula aggregation technique were mated to C57BL/6 female mice. After achieving germ-line transmission, LRP5+/- females were crossed with LRP5+/- males to obtain LRP5-deficient mice. One line of mice lacking LRP5 gene was confirmed by Southern blotting. Such knock-out mice may serve as an effective animal model to study in vivo function of LRP5 gene.

  • Domestic southwest offshore wind farms have problems such as the reduction in fishing rights by prohibiting vessel traffic, which delays their development. As such, there is a need to develop offshore windfarms in Europe to permit the passage of vessels and fishing operations in specific offshore windfarm areas. In this study, we used the environmental stress (ES model) and the IALA Waterway Risk Assessment Program (IWRAP) to determine the ratio of risk to the route type (cross pattern, grid pattern) and traffic volume (present, 3 times, 5 times and 10 times) to derive the risk factors of specific vessels for offshore windfarms. As a result, ship operators' risk related to offshore windfarms did not rise in both route types and there was no significant difference in the annual probability of collision in the present traffic volume. In conditions that increased traffic volume by 3 times, 5 times and 10 times, the risk ratio increased as ship operator risk and collision probability increased at the crossing points. Furthermore, when the traffic volume of the ship increased, the risk could be more effectively distributed in the grid route compared to the cross route. The results of this study are expected to apply to the operation type, route operation method, safety measures, etc. in offshore wind farms.

  • ESS(energy storage system) has recently become an important power source in various areas due to increased renewable energy resources. The more ESS is used, the less the effective capacity of the ESS. Therefore, it is important to manage the remaining useful lifetime(RUL). RUL can be checked regularly by inspectors, but it is common to be monitored and estimated by an automated monitoring system. The accurate state estimation is important to ESS operator for economical and efficient operation. RUL estimation model usually requires complex mathematical calculations consisting of cycle aging and calendar aging that are caused by the operation frequency and over time, respectively. A lightweight RUL estimation model is required to be embedded in low-performance processors that are installed on ESS. In this paper, a lightweight ESS RUL estimation model is proposed to operate on low-performance micro-processors. The simulation results show less than 1% errors compared to the original RUL model case. In addition, a performance analysis is conducted based on ATmega 328. The results show 76.8 to 78.3 % of computational time reduction.

  • Neben der staatlichen Gerichtsbarkeit gibt es eine gesetzlich legitimierte Schiedsgerichtsbarkeit durch Privatpersonen nach dem Schiedsverfahrensrecht. Diese Institution entwickelte sich zwar als $\ddot{U}bergangsstufe$ von der Selbsthilfe zur staatlichen Gerichtsbarkeit und aber erlangt zur Zeit mit dem Wirtschaftswachstum, vor allem mit der Verschmelzung des internationalen Handels eine hervorragende Stellung im Justizsystem. $F\ddot{u}r$ die weitere Entwicklung der Schiedsgerichtsbarkeit ist die $Unterst\ddot{u}tzung$ und Kontrolle des staatlichen Gerichts von großer Bedeutung. In der vorliegenden Arbeit handelt es sich $haupts\ddot{a}chlich$ um die Rolle und Grenze des Gerichts in der Schiedsgerichtsbarkeit. Dabei ist die Rolle des Gerichts in 3 Teilen geteilt untersucht, und zwar die aktive, die passive und die kontrollierende Rolle des Gerichts. Unter der ersten $geh\ddot{o}ren$ das Eingreifen des Gerichts in das Schiedsverfahren, z.B. bei der Bestellung und Ablehnung des Schiedsrichters und bei der Frage $\ddot{u}ber$ die Bedendigung des Schiedsrichteramtes und die einstweiligen Maßnahmen des Gerichts sowie die $Unterst\ddot{u}tzung$ des Gerichts bei der Beweisaufnahme. Weil das Schiedsgericht keine Zwangsgewalt besitzt, ist die Schiedsgerichtsbarkeit in bestimmten $F\ddot{a}llen$ auf die aktive Mitwirkung des Gerichts stark angewiesen. Die Rolle des Gerichts in der Schiedsgerichtsbarkeit ist aber durch die Entscheidungsbefugnis des Schiedsgerichts $\ddot{u}ber$ die eigene $Zust\ddot{a}ndigkeit$ und $\ddot{u}ber$ die $G\ddot{u}ltigkeit$ der Schiedsvereinbarung(sog. Kompentz-Kompetenz) und durch den einstweiligen Rechtsschutz durch das Schiedsgericht $eingeschr\ddot{a}nkt$. Hier $beschr\ddot{a}nkt$ sich das Gericht auf die passive Rolle. Die Schiedsgerichtsbarkeit ist außerdem der Kontrolle durch das staatliche Gericht zu unterziehen, sei es durch die Aufhebungsklage oder sei es durch die Entscheidung $\ddot{u}ber$ die Vollstreckung des Schiedsspruchs. Besonders im $Vollstreckbarerkl\ddot{a}rungsverfahren$ hat das ordentliche Gericht eine umfangreiche $\ddot{U}berpr\ddot{u}fungsm\ddot{o}glichkeit$ des Schiedsspruchs. Einerseits soll die Stellung der Schiedsgerichtsbarkeit nicht durch die Mitwirkung und Kontrolle des staatlichen Gerichts entwertet werden, andererseits ist es aber Aufgabe des Staates, die Richtigkeit der schiedsgerichtlichen Entscheidung zu garantieren. In der Schiedsgerichtsbarkeit ist auch das Rechtsstaatsprinzip aufrechterhalten zu bleiben. Abschließend ist festzustellen, daß die Schiedsgerichtsbarkeit ohne Mitwirkung des staatlichen Gerichts nicht auskommt, die Rolle des Gerichts aber auf das erforderliche Maß $beschr\ddot{a}nkt$ sein sollte.

Zur Problematik von Werbetextanalysen nach einem Kommunikationsmodell - in bezug auf den Gebrauch der deiktische $Ausdr\"{u}cke$ wie 'es' und 'it' - (의사소통 모델에 따른 광고분석의 문제점 - 광고의 지시어 사용을 중심으로)

  • In der vorliegenden Arbeit wird die Interpretationsproblematik bei Werbetextanalysen in bezug auf das Kommunikationsmodell von Shannon & Weaver (1949) untersucht. Dabei geht es vor allem urn deiktische $Ausdr\"{u}cke$, wie 'es' im Deutschen und 'it' im Englischen, die ihre Antezedens in der Werbung nicht eindeutig angezeigt haben. Die Kommunikation basiert ja auf den drei grundlegenden Elementen: Sender/Sprecher, Information (Kanal), und $Empf\"{a}nger/Horer$. Im Kommunikationsvorgang ist jeweils der Rollenaustausch zwischen Sender und $Empf\"{a}nger$ enthalten. Sowinski (1998) hat die Werbung nach diesem Kommunikationsmodell analysiert. Bei der werblichen Kommunikation aber fallen einige Besonderheiten auf, die nur der Werbekommunikation eigen sind. Sowinski nannte $f\"{u}nf$ werbespezifische Charakteristika, die einerseits als einseitiger $Verstandigungsproze{\ss}$ und andererseits als fehlende Kontroll- und Korrekturfunktion $gegen\"{u}ber\;dem\;H\"{o}rer$ und dadurch als $unbeschr\"{a}nkte\;Interpretationsm\"{o}glichkeiten$ von Seiten des Horers aufzufassen sind. In bezug auf die besonderen Charakteristika von Werbung wurden in dieser Arbeit hier einige kritische Bemerkungen gegen zwei Argumente vorgetragen: Die Kritik richtet sich einmal gegen das auf den konversationellen Implikaturen beruhende Modell von Lee (2000) und zum anderen gegen die strategischen $Ans\"{a}tze$ zur Interpretation von Werbetexten bei Oh (1999a, 1999b). Die $Vorschl\"{a}ge$, die in den $Argumentationsg\"{a}ngen$ der beiden Autoren als vorteilhaft $f\"{u}r\;die\;Interpretationsm\"{o}glichkeiten$ von Werbebotschaften gelten sollen, scheinen jedoch die besondere Form der werblichen Kommunikation nicht berticksichtigt zu haben.
