In metropolitan railway systems, the average commuting time keeps increasing as the scheduled speed increases, and this leads to a decline of rail service usage and competitiveness. Therefore, effective express operation for urban trains is required to improve the scheduled speed. In this study, based on the obtainable time shortening efficiency and economic viability, several express operations are suggested for urban railways and these suggestions are compared by considering high performance trains with acceleration/deceleration and maximum speed improvement. As a result, the optimum express system, which can minimize the cost for sidetrack construction, is suggested.

Honorific forms express the speaker's social attitude to others and also indicate the social ranks and level of intimacy of the participants in the discourse. In a cross-linguistic perspective of grammar engineering, modelling honorification has been regarded as a key strategy for improving language processing applications. Using the HPSG and MRS formalism, this article provides a multilingual grammar model of honorification. The present study incorporates the honorific information into the Meaning Representation System (MRS) via Individual Constraints (ICONS), and then conducts an evaluation to see if the model contributes to semantics-based language processing.

China's logistics industry is an growing one at a very higher rate, owing to the rapid expansion of the country's industrial base and the rise of domestic consumer markets. Essential to the development of china's economy, policy makers have paid constant attention to the logistics sector which is attracting growing volumes of both foreign and domestic investment. The inefficiencies are exacerbated by a number of factors such as transportation bottlenecks, regulatory constraints and local barriers to entry. Foreign and foreign-invested logistics companies have typically cornered the express delivery (for example DHL, FedEX), sea freight forwarding and specialized logistics services (for example Hanjin Shipping). The purpose of this paper is to contribute to the activation of Korean companies' entry into China's logistics market by studying the strategies and types for Korean companies enter into China's logistics Market.

Telomerase reverse transcriptase (TERT) is an enzymatic ribonucleoprotein that prolongs the replicative life span of cells by maintaining protective structures at the ends of eukaryotic chromosomes. Telomerase activity is highly up-regulated in 85-90% of human cancers, and is predominately regulated by hTERT expression. In contrast, most normal somatic tissues in humans express low or undetectable levels of telomerase activity. This expression profile identifies TERT as a potential anticancer target. By using an RNA mapping strategy based on a trans-splicing ribozyme library, we identified the regions of mouse TERT (mTERT) RNA that were accessible to ribozymes. We found that particularly accessible sites were present downstream of the AUG start codon. This mTERTspecific ribozyme will be useful for validation of the RNA replacement as cancer gene therapy approach in mouse model with syngeneic tumors.

In an express tilting train, side wall insulating the noise from the exterior sound source consists of two parts. One is the layered composite panel including aluminum honeycomb, glass wool and nomex honeycomb. The other is the double glazed window. In this study, sound insulation performance of the two parts is investigated by mass law and experiment. Based on ASTM E2249-02, the intensity sound transmission loss (TL) is measured on the specimens of the two parts. Mass law deviation (MLD) is considered in order to compare the sound insulation performance in respect of weight. Contribution of each part to the sound insulation is analyzed and the sound insulation strategy for the interior noise reduction is investigated.

Citizens of 21st century which is called to be the era of 'Culture' express their cultural desires in their public environments. Governments found that these needs can be satisfied through the culture-centered public designs which are based on the local resources and identities. This research suggests the strategy programming model to support these projects. It aims at not suggesting the conceptual process model, but developing the practical supporting model with options to choose. Thus the indices which are related to each prototype phases of programming process are analyzed through the case analyses with qualitative approach. This paper focused on analyzing the indices for Place Strategy which includes the phases for Resource, Mission, and Targeting. Altogether, 81 indices are analyzed.

Research on strategic Code-Switching (CS) of second language learners in teaching English in English (TEE) program provides an elaborate framework for analyzing how learners manage to express themselves in spite of their limited knowledge of the target language. This research presupposes that L2 learners' CS presents innovative solutions for communicative strategy, and that CS used as communicative strategy can promote L2 learners' language acquisition. The major questions of current research involve examining the significant patterns of different functions of CS in L2 learners' interaction and investigating L2 learners' CS styles according to the different functions of CS. The implication of CS utility is regarded as a teaching technique in the TEE program. Recorded transcript is analyzed to trace the same pattern and the categorization of CS as well as to recognize the functions of CS and their ratio. Hence, this leads to the conclusion that learners' negotiation between code selection and communication intention occurs in patterns. The learners' CS tends to be predictable, reproductive, and systematic, as one of the language acquisition phases. Therefore, the attention to the CS in the TEE program should be redirected in communication substantiality toward the principles of pragmatics. As an additional advantage of the CS analysis, this research elaborates on a conceptual acceptance of CS as a set of learners' strategies in the TEE program.

The income level of people in South Korea has risen as the gross national income per capita reached the milestone of 30,000 dollars. More and more consumers try to change their houses according to their tastes just like they express themselves through clothes, bags, and other fashion items, thus pursuing value-based consumption. The changes to the housing culture including the greater percentage of one- or two-person households and the growing trend of lease and monthly rent have made consumers increase their demands for products to express their lifestyles. As a result, global lifestyle shops with characteristic and diverse concepts entered the South Korean market and were joined by South Korean fashion brands, large-sized stores, department stores, and fancy stationery manufacturers, which launched their own brands, in the expansion of lifestyle shops across the nation. Lifestyle shops have a couple of unique attributes including the relatively clear selection of target consumers and a clear set of VMD strategies accordingly. Based on a judgment that there was cost differentiation among brands, the investigator categorized the comparison and analysis criteria into high, middle, and low prices to apply case analysis. This study set out to analyze VMD strategies for spatial composition through cost differentiation among lifestyle shops, take the results into total consideration, and propose an effective and competitive VMD strategy for lifestyle shops through spatial composition elements.

In daily life, another major role of human hand is a communicative function using hand gestures besides grasp function. Therefore, if amputees can express their intention by the prosthetic hand, they can much actively participate in social activities. Thus, this paper propose myoelectric multi-function prosthetic hand which can express 6 useful hand gestures such as Rock, Scissors, Paper, Indexing, Ok and Thumb-up. It was designed as under-actuated structure to minimize volume and weight of the prosthetic hand. Moreover, in order to effectively control various hand gestures by only two EMG sensors, we propose a control strategy that the signal type are expanded as "Strong" and "Light", and hand gestures are hierarchically classified for the intuitive control. Finally, we prove the validity of the developed prosthetic hand with the experiment.
