Let R be a prime ring with center Z and characteristic different from two, U a nonzero Lie ideal of R such that $u^2{\in}U$ for all $u{\in}U$ and $d$ be a nonzero (${\sigma}$, ${\tau}$)-derivation of R. We prove the following results: (i) If $[d(u),u]_{{\sigma},{\tau}}$ = 0 or $[d(u),u]_{{\sigma},{\tau}}{\in}C_{{\sigma},{\tau}}$ for all $u{\in}U$, then $U{\subseteq}Z$. (ii) If $a{\in}R$ and $[d(u),a]_{{\sigma},{\tau}}$ = 0 for all $u{\in}U$, then $U{\subseteq}Z$ or $a{\in}Z$. (iii) If $d([u,v])={\pm}[u,v]_{{\sigma},{\tau}}$ for all $u{\in}U$, then $U{\subseteq}Z$.

Partial characterization of B. thuringiensis var. kurstaki 3ab temperature-sensitive mutants was carried out through biochemical analyses, utilization tests of carbohydrate sources, antobiotic resistant test, hemolytic reaction test, growth measurement of Fructus gardenia sxtrant medium and toxicity test against mice. Six ts mutants, ts-U154, ts-U601, ts-U602, ts-U603, tsU-604, and ts-U788 could not produce urease, ts-U603 lost its motility, ts-U154 could not use salicin and cellobiose and ts-U603 not ribose. All ts mutants except ts-U154 and wild type strain were resistant to cephalothin, ampicillin, and penicillin. but ts-U154 was sensitive to the three. Four mutants, ts-U21, ts-U74, ts0U131 and ts-U154 did not form pigment colonies on the F. gardenia medium. All the mutants and wild type strain showed hemolysis reaction on the blood agar. The B. thuringiensis and mutants were not toxic to mice.

For the development and management of u-City(ubiquitous city), Ubiquitous City Construction Law was enacted(March 3, 2008) to form the legal basis of u-City plan, construction and managements afterwards. The ultimate goal of the u-City construction is the advancement of national territory utilization and management using Korea's high level of IT and spatial information infrastructure. Based on the definition of the u-City Construction Law, the u-City refers to a city where u-City services are provided through the u-City infrastructure applying u-City technology. But, based on the current level of relationship model among u-City service, technology and infrastructure, it is not enough to guide the local municipalities to plan and provide the successful u-City services in its vicinity. So as one of the core issues for the legal arrangements of successful u-City services, the purpose of the study is to suggest the basic directions and execution strategies for the relationship establishment among u-City service, technology and infrastructure.

The u-City construction plan being executed presently involves such problem that services are provided in a suppliers-oriented direction while there are not much discussions on what u-Services citizens should be provided with and what u-Services that city government the supplier shall provide. In order to implement citizen-friendly u-Services the type of u-Services that offer just the right services efficient and convenient for citizens, u-Services should be provided based on active researches on the citizens' use and utilization of u-Services rather than u-Services being provided in suppliers' perspective as so far. To that end, there need be recognition and well-organized methodology that u-Services should be provided through humane, social and scientific analysis of the citizens that are to be provided with u-Services. Thus, in this study, the process of u-Services being transmitted was re-interpreted as background theory to deduce and apply services appropriate for u-Residential Space, and service science for u-Services the scientific and overall approach to seek for service innovation was applied to the development of u-Service deduction method based on such background theory. The u-Service methodology developed based on service science is judged able to deduce and provide u-Services appropriate for the intended services through scientific analysis of citizen-friendly u-Services.

As the ubiquitous technology has been widespread, the u-service development in the private sector is increasing these days. Especially, consisting of various life spaces, a mixed-use complex started actively utilizing the ubiquitous technology in order to provide users with differentiated services. In this paper, a new development methodology of the u-service for a mixed-use complex is proposed. Because the ultimate purpose of the u-service in a mixed-use complex is to guarantee profitability, the u-service must accelerate commercial activities among various users in the complex. The u-service development methodology of a mixed-use complex proposed in this paper firstly defines various perspectives for the u-service and identifies specific u-service elements in cross points of the perspectives. Then with those u-service elements, the methodology generates a u-service pool. Finally, after evaluation process, target u-serviced to develop are selected. Having designed the u-service development methodology, we expect the methodology to contribute the successful implementation of u-service model for a mixed-use complex.

U-Services are inevitably essential for the realization of u-Cities. Most local governments in Korea have expressed much interest in introducing u-Cites and related u-Services. Since researchers anticipate that developing u-Cities will produce economic effects, the Korea government has support local governments to develop u-Cities and necessary u-Services. However, the technology issues have been dominiated in the field of U-City services and most of the U-City services do not reflects all the complicated and pluralistic sides of environment, which are caused by future uncertainties in developing u-Cites. For the purpose of addressing the above uncertainties, this paper attempts to develop the possible scenarios for U-City services through a scenario planning approach. A focus group interview and survey with professionals in the field of planning u-Cities was performed to identify these uncertainties. Then, in order to investigate the validity of the scenario planning methodology, the u-Service "u-Water purity monitoring" is adopted. After considering the relevant issues, we developed two possible scenarios: a mutual linkage service among u-Service related organization and a cooperating and coordinating service among local governments. On the basis of these scenarios, the strategies for potential U-City services are formulated. Various participants in developing U -City services are encouraged to use the scenarios as the foundation of predicting future features of u-Cities and developing the framework of the U-City service scenarios effectively.

Seit dem Ereignis des Tunnbaus zu Babel. versucht man, Sprachbarriere zu $\"{u}berwinden$. Eine dieser $Bem\"{u}hungen$ hat seit der 60er Jahre zur Anwendung von Computern in der $\"{U}bersetzung gef\"{u}hrt$. Bei der automatischen $\"{U}bersetzung\;\"{u}bernimmt$ der Computer die Aufgabe, Texte von einer $nat\"{u}rlichen$ Sprache in eine andere zu $\"{u}bertragen$. Die vorliegende Arbeit $besch\"{a}ftigt$ sich mit verschiedenen Arten von den sogenannten $\"{U}bersetzungspatterns\;f\"{u}r$ die automatische $\"{U}bersetzung$ Koreanisch­Deutsch. Zu den $\"{U}bersetzungspatterns\;geh\"{o}ren$ u.a. Verbphrasen-Pattern, Nominalphrasen-Pattern und Verbindungspattern. Unter 'Verbphrasen-Pattern' versteht man einen gekoppelten Subkategorisierungsrahmen der Verben zweier Sprachen. 'NominaIphrasen-Pattern' verstehen sich als $\"{U}bersetzungspattern$ der Nominalphrasen. Unter 'Verbindungs-Pattern' werden $\"{U}bersetzungspattern$ von komplexen $S\"{a}tze$ verstanden, wie z.B. Satzkoordinationen und $S\"{a}tze$ mit eingebetten $S\"{a}tzen$. Als Vorteil des Ansatzes $z\"{a}hlen$ u.a. die Wiederverwendbarkeit bzw. das leichte Management der Patterns, die $Beschreibungsm\"{o}glichkeit$ in der lexikalischen Ebene, die Generieung der naturlichen $Ziels\"{a}tze$ und die leichte Verbesserung der $\"{U}bersetzungsqualit\"{a}t$. Die in dieser Arbeit vorgestellten $\"{U}bersetzungspatterns\;k\"{o}nnen$ aIs Hilfsmittel $f\"{u}r$ Deutschunterrichte, Aufsatzhilfesysteme und elektronische Koreanisch-Deutsch $W\"{o}rterb\"{u}cher$ eingesetzt werden.
