Object : The purpose of this study is to observe the correlation between change in pattern identification symptoms and scandinavian stroke scale in ischemic stroke patient who had receive traditional Korean medical treatment and conservative treatment. Methods : 43 subjects were recruited from patients with ischemic stroke within 30 days of onset. We chose the subjects who had at least one follow up session and had checked the score between last follow up session and first session in pattern identification and scandinavian stroke scale. We also assessed the correlation between pattern identification and scandinavian stroke scale. Results : There were significant negative correlation between pattern identification and scandinavian stroke scale in Fire-heat pattern and positive correlation in Dampness-phlegm pattern. Conclusions : This study provides evidence that collaborative treatment maybe effective in improving neurologic symptoms in ischemic stroke patients diagnosed as Fire-heat pattern. Further studies with larger scale and longer observation period, more neurologicscales scales, control group would be required.

A 512-bit Task Programmable ROM has been designed and fabricated using PMOS technology. The content of the memory was written through the gate pattern during the fabrication process, and was checked by displaying the output of the chip on an oscilloscope with 512(32$\times$16) matrix points. The operation of the chip was surcessful with operating voltage from -6V to -l2V, The power consumption and propagation delay time have been measured to be 3mW and 13 $\mu$sec, respectively at -6 Volt. The power consunption increased to 27mW and propagation delay time decreased to 3$\mu$sec at -12V. The output of the chip was capable of driving the input of a TTL gate directly and retained a high impedence state when the chip solect function disabled the output.

Tatan is a symbol of kinship and belonging in Scotland and a badge of identity recognized all over the world. Alongside the powerful historical and national resonance to Tartan for Scots it has been borrowed repeatedly by fashion. The pattern compositionof Tartan check is formed as a typical cross stripes that vertical line and hrizontal line meets rectangulary. And its color is much various and rich than other check pattern. So its magnificient spec-tacle that various all kinds of colors is dyed in cloth is second to name. Today we are as likely to meet tartan in a couturier dress as in a kilt or plaid. Tartan is distinctive in colour style and de-sign. It conveys personality ceremony and drama. All these aspects of its character have contributed to tartan being one of the best-known and best-loved fabrics in the world. In other parts of Europe traditional checked patterns declined and disappeared but in Scotland tartan survived strongly jist as the bagpipes also European flourished Due to geographical and cultural circumstances Scots were able to develop and enhance tartan and its remarkable individuality ensured its sur-vival in spite of adverse political and economic pressures. Tartan has been adopted as the national dress of all Scots. Lowland and High-land providing a powerful form of national cultural and personal identity. Whether tra-ditional or a recent creation whether tra-ditional or a recent creation whether a symbol of nationality or a substitute for nationhood tartan is no mean achievement.

The characteristics of rock fractures for engineering rock classification are investigated by analyzing three dimensional point cloud generated from adjusted digital images of a tunnel face during construction and the tunnel is reinforced based on the supporting pattern suggested by the RMR and the Q system using parameters extracted from those images. As results, it is possible saving time required from face mapping to tunnel reinforcing work, enhancing safety during face mapping work in tunnels and reliability of both the mapping information and selecting supporting pattern by storing the files of digital images and related information which can be checked again, if necessary sometime in the future.

RTP (rapid thermal pressing), one of micro-pattern replication techniques like hot embossing, is focused on achieving shorter cycle time. DFSS(Design for Six Sigma) has been applied in order to enhance the completeness of the development process for RTP system. According to DIDOV roadmap, we derived design concepts and subsequently decided the main performances, design factors, and components for RTP system. In the design process of RTP system using finite element analysis, it was realized that its structural characteristics affect large area replicability. Optimizing structural design factors, based on CAE, it was checked out that its large area replicability could be improved in a virtual test. Finally, we have a plan to validate the large area replicability of the developed RTP system, by performing micro-pattern replication tests with polymeric sheets.

Tensile strength is considered key properties for characterizing rock material in engineering project. It is determined by direct and indirect methods. Point load test is a useful testing method to estimate the tensile strengths of rocks. In this paper, the effects of rock shape on the point load index of gypsum are investigated by PFC2D simulation. For PFC simulating, initially calibration of PFC was performed with respect to the Brazilian experimental data to ensure the conformity of the simulated numerical models response. In second step, nineteen models with different shape were prepared and tested under point load test. According to the obtained results, as the size of the models increases, the point load strength index increases. It is also found that the shape of particles has no major effect on its tensile strength. Our findings show that the dominant failure pattern for numerical models is breaking the model into two pieces. Also a criterion was rendered numerically for determination of tensile strength of gypsum. The proposed criteria were cross checked with the results of experimental point load test.

Intrusion detection is a process that identifies the attacks and responds to the malicious intrusion actions for the protection of the computer and the network resources. Due to the fast development of the Internet, the types of intrusions become more complex recently and need immediate and correct responses because the frequent occurrences of a new intrusion type rise rapidly. Therefore, to solve these problems of the intrusion detection systems, we propose a sequential pattern miner for analysis of the alert data in order to support intelligent and automatic detection of the intrusion. Sequential pattern mining is one of the methods to find the patterns among the extracted items that are frequent in the fixed sequences. We apply the prefixSpan algorithm to find out the alert sequences. This method can be used to predict the actions of the sequential patterns and to create the rules of the intrusions. In this paper, we propose an extended prefixSpan algorithm which is designed to consider the specific characteristics of the alert data. The extended sequential pattern miner will be used as a part of alert data analyzer of intrusion detection systems. By using the created rules from the sequential pattern miner, the HA(high-level alert analyzer) of PEP(policy enforcement point), usually called IDS, performs the prediction of the sequence behaviors and changing patterns that were not visibly checked.

In this study two dimensional visco-plastic finite element model capable of handling the multi-step excavation was developed for investigating the effect of excavation support sequences on the behavior of underground openings in the jointed rock mass. First, the finite element model which is capable of handling the multi-step excavation is developed and verified. And then the model is combined with visco-plastic joint model. Ubiquitous joint pattern was considered in the model and joint properties in cach set were assumed to be indentical. Passive, full-grouted rockbolts were cosidered in the numerical model. The visco-plastic deformations of joints and rockbolts were assumed to be governed by Mohr-Conlomb and von Mises yield criteria, respectively. With the ability of removing elements, the model can simulate the multi-step excavation-suppport sequences. The reliability and applicability of the model to the stability analysis for the underground excavation in pratice was checked by simulating the behavior of underground crude oil storage caverns under construction.

Construction of the coping of reinforced concrete piers is very complicated due to heavy density of rebars and usually exposed to negligent accident. To correct these problems, coping is pre-assembled at the ground in pier coping pre-assembly method and recently a new method of rebar assembling has proposed in this study. For safety assessment of proposed method, small scale model test of railway bridge(PSC U-GIRDER T-shaped pier) was carried out and it was verified that crack pattern, failure mechanism and load resistance capacity are similar between existing method and proposed method. And using analytical approach, linear and non-linear finite element analysis was performed. As a result, it was checked that proposed method has an acceptable structural safety.
