Linguistics which is bent on establishing strict scientific logic to everyday language as its main subject was prone to be inactive in study of literature. Interpretation in the dimension of art was considered as a realm of literature. However if linguistics should open itself to diverse and characteristic aspect and function of language then literature is truly one of the most important source for uncovering poetic function, aesthetic aspect and process for creation of beauty of language. Recently level of linguistic interest in works of Korean literature has been heightened. Thus value and importance of language in literary works have been recognized and people concerned are contemplating profoundly about what can be done by Korean language for literature works and linguistic analysis of poems and novels have been carried out. Poet Yun Dong-Ju among many other Korean poets of middle standing while enduring and internalizing time he had took the path of self verification process thoroughly. Literary language which was used in the process of Poet Yun Dong-Ju`s watching, enduring and aesthetizing is considered as very valuable in searching for poetic function, aesthetic function and creating of meaning. Thus this author attempted to broaden horizon of literary language through analysis of the Poet Yun Dong-Ju`s poems and to disclose identity and secret of literary language clearly and precisely through this study. Literary language being used in the process of Poet Yun Dong-Ju`s watching, enduring and aesthetizing is viewed as very valuable for search of its poetic and aesthetic function and creating of meaning. Furthermore Poet Yun Dong-Ju contributed to extending horizon of literary language by expressing predicates in diverse aspects.

The necessity of online dynamic security assessment is getting apparent under Electricity Market environments, as operation of power system is exposed to more various operating conditions. For on-line dynamic security assessment, fast transient stability analysis tool is required for contingency selection. The TEF(Transient Energy Function) method is a good candidate for this purpose. The clustering of critical generators is crucial for the precise and fast calculation of energy margin. In this paper, we propose a new method for fast decision of mode of instability by using stability indices and energy margin. The method is a new version of our previous paper.[1] Case studies are showing very promising results.

The emergence of competitive power market makes dispatch algorithm with transient stability constraints increasingly important for the transparent power system operation. HeurisTTC and off-line evaluation for the operation point can produce a discrimination among market players in the deregulated power system. In this paper, a dispatch algorithm with transient stability constraints is proposed. Energy margin under the TEF(Transient Energy Function) structure is adopted as a measure for the stability index. Implementation issues and simulation results are discussed in the context of a l0-bus system

Magnesium has been gained increased attention in recent years as a structural metal, especially in the automotive industry. These alloys have higher strength/weight ratio, heat conductivity and recyclability compare to other alloys. To fully benefit from the whole designing potential of this material, joining processes have to be developed. Laser welding turns out to be very suitable to join magnesium parts. Because laser welding allows, in comparison to conventional welding techniques like MIG and TIG welding, a low thermal load when joining the components. This paper presents the laser weldability of magnesium alloy by CW Nd:YAG laser. The mechanical properties of the joints are investigated, and the possibilities of industrial use are presented.
