Though the maintenance monitoring of structurally weak parts of the tunnel structure in public service must be judged in connection with the monitoring during the construction period for analysis of the behavior of the ground and surrounding structures following the tunnel excavation for the effective management, the monitoring during the construction period and the maintenance monitoring are implemented separately on the basis of the periods of construction and maintenance, so the connectivity and systematic management of the related data are mostly inadequate. The improvement direction is suggested in this thesis, by analyzing the problems of tunnel monitoring in the domestic design criteria. And, it is anticipated that from now on the use of hi-tech sensors and wireless communications technology will proceed vigorously in the maintenance, so considering these situations, the development and application of the maintenance monitoring system and the revision of the domestic design criteria and specification are needed in the future.

In east Asia, the leaves of various Sasa species have been used in folk medicine for centuries. The effects of the methanolic extract and its subsequent fractions derived from the leaves of Sasa quelpaertensis Nakai on cell proliferation in human leukemia HL-60 cells were evaluated. The ethyl acetate fraction of this extract (ESQL) significantly reduced cell viability in a dose-dependent manner ($0-250\;{\mu}g/mL$). ESQL ($IC_{50}=24.8\;{\mu}g/mL$) exhibited growth inhibition comparable to the main constituent of green tea, epigallocatechin ($IC_{50}=26.2\;{\mu}g/mL$), which was used as a positive control. ESQL treatment induced apoptosis, which was confirmed by the presence of nuclear condensation and annexin V-staining. These results demonstrate that ESQL contains chemopreventive phytochemicals that may be useful in neutraceutical applications.

As the era of change that has developed a variety of media. But no matter how hi-tech media it, even though several of the previous circular forms of media have evolved from. Jay David Bolter and Richard Grusin them academically for "old media remediation will use," he explains. The middle of media, especially games remediation nature of the game, the game plan, game content, game machines, etc. in various parts of the outward form, there is remediation characteristics. The use of these remediation allows users to facilitate access to the media, and more importantly are able to adapt quickly to the game controls. And Increase the fun of the game, given the immersion for the game that enhance the role is. Remediation of the game against a variety of elements in the game if they utilize in-depth research on the development of the game has been suggested that the role is a lot.

In recent automotive industry, vehicle weight can be reduced by one-step forming of tailored blanks welded with two or more sheets of metal blanks. Tailored blank(TB) welding is a production method for blanks involving welding together materials of different quality, thickness, and coating, and has proved popular in fabrication automotive parts. This paper deals with the forming characteristics of mash seam welded tailored blanks. Using these forming characteristics, the bumper beam was developed using the mash seam welded tailored blank with the different thickness. We performed the forming simulation with respect to strain distribution on blank during the stamping of the bumper rail part. Based on these results, we made some stamping tryouts with selected types of blank designs to investigate the formability of tailored blank with different thickness. During the tryouts, we knew that it was important the BHF(Blank Holding Force). We obtained to reducing 10.5% weight and cost with adapting the bumper beam of automotive component using the tailored blank of mash seam welding.

The purpose of this study is to draw out the features of expressions about Nature in Korean interior design, because the Nature has been being very important theme in the interior space. So, the 68 cases of domestic famous interior designers' works during last ten years were selected from authorized design magazines like as INTERIORS, MARU and so on. And next, the cases were analysed in according to interior image style, design elements used for effect of Nature and the direction of expression(directly or indirectly), As the results, composite expressions with a few elements were found in modern, hi-tech, elegant, minimal and casual styles, while direct expressions with many elements were found in natural and ethnic styles. And main elements for effect of Nature were trees and stones. Among many elements, water and stones became more important elements after 2000 than before. In the meantime the use of composite expressions was being increased and so appeared even in natural and ethnic styles.

This study was carried out to evaluate the high rate biological reactor such as lab scale reactor before the application in site, and to get the basic data for possibility using liquid fertilizer with the effluent from biological reactor when the centrifugal machine was applied. The total volume of this reactor in 6 L, in composted of anoxic reactor (2 L), aerobic reactor (2 L), and nitification reactor (2 L). BOD removal efficiency rates when centrifugal machine was applied after effluent from biological reactor are over than 95%. This biological reactor was required post process to satisfy the effluent standards, and was need centrifugal machine to control the washout of microbes in the reactor. T-N removal efficiency rate in HRT 24 hr with centrifugation is 80.0%, and it is desirable to operate less than $1.3kgN/m^3{\cdot}d$ for 70% of T-N removal efficiency rate. T-P removal efficiency rate in HRT 24 hr is 68.2%, and become higher 71.3% after centrifugation. Considering in the 28.6% T-N removal efficiency rate, the nitrogen contents of the effluent from reactor is 0.34% to satisfy the liquid fertilizer.

This study is to examine the types of expression and aesthetic characteristics of on-line game characters by analyzing those game characters' body and their costume that appear in various domestic on-line game sites. It is shown in this study that types of the human bodies and costume expressed through the game characters are grouped into five categories such as exposure and tightness, enlargement and exaggeration, curtailment and simplification, gender stereotype and unification. Furthermore, there are four typical aesthetic characteristics resulting from those types of expressions; First, 'grotesque' is expressed in the form of extreme enlargement and exaggeration, extreme exposure and concealment, combined images among human, animal or machine, or monstrous devilish images. Second, in an effort to express 'eroticism', bodies are directly exposed, see-through costumes are used in order to emphasize the body lines or very tight designs are used. Third, 'futuristic' characteristics are shown through geometrical shape and silhouette, machine-like details, strong artificial colors or glossy hi-tech material. Lastly, 'pastiche' is expressed with reconciliation of variety of costumes of game characters. Various opposite or heterogeneous styles are combined or harmonized each other to show pastiche, of which examples are male and female, superior culture and inferior one, rich and poor, oriental and western, human and machine, human and nature or past and future, etc.

The rapid development of information media in the 21th century has given rise to the acceleration of fashion change and its diversification due to individual lifestyle, the personification and differentiation of consumers. This has got away from the function-centeredness of clothing and awakened people to the important task of hi-tech new materials development and design development. We immediately need to develop the measure to cope quickly and properly with changes in the dwindled fabric market. Consumers; needs are personified and diversified and the cycle of fashion materials become curtailed. From this perspective, this study attempted to manufacture the material for capable of satisfying consumers; psychology and needs with the handicraft based on the multi-item and small-quantity production system. This study attempted to present the possibility of differentiating products and developing diverse materials by applying the Woolsmok technique. It is expected that the development of these materials will not simply stay at the level of handicraft but contribute to the competitive materials of creativity and aesthetics by inducing it to be applicable to the industrial world and activate them as differentiated high-grade clothing materials for consumers at home and abroad.

Using the service innovation system model, the development of Korean online game industry is analyzed. The model proposed by Gallouj (2002) is modified in order to reflect IT service characteristics such as network externalities. Success factors and innovations patterns of Korean online game industry are examined. First, at the early stage of her growth, Korean online game industry was not supported or coordinated by any Government policies unlike DRAM, CDMA or TFT-LCD. Many parts of technical and service innovations were unintentionally initiated by online game developing ventures without predeterminde strategies. Second, the online game industry is basically a service industry so that users' needs and technical and service characteristics are intertwined to produce innovation. The innovation system of the online game industry is quite different from conventional product technological innovation systems in a sense that there are no blueprints for innovation as well as major players in the system. Third, Government's policies for promotion of IT industry such as the broadband infrastructure installation policy, the hi-tech venture promotion policy and the military exemption policy contributed greatly to development of the online game industry. However, these policy tools were not intended for online game industry but in the end gave a great impact on the service innovation system of the online game industry.
