This paper describes external and internal stability of reinforced earth wall using large-scale modular block and geogrid reinforcement. The evaluation for external and internal stability was conducted to analyze effect of wall height, reinforced soil (or backfill soils) and reinforcement strength. The external stability showed that the analysis cases were satisfied with design criteria, when the required minimum length and vertical spacing of reinforcement were 0.7H and 1m, respectively. The internal stability conformed that some cases were satisfied with design criteria in $25^{\circ}$ of internal friction angle of reinforced soil. Expecially, it will be applicable as wall structure considering a structural stability and economic efficiency based on evaluation of internal stability.

Background : The tonsillar region is innervated by the sensory components of the glossopharyngeal nerve(IX) which communicates with certain part of cervical sympathetic ganglion. Some authors suggest stellate ganglion block(SGB) is effective for treatment of recurrent tonsillitis. The goal of this study was to evaluate the effect of SGB in controlling pain after tonsillectomy. Methods : Forty five patients, evaluated to ASA class 1 and 2, scheduled for tonsillectomy under general anesthesia were randomly assigned to 1 of 3 groups (group I: control; group II: SGB with 1% lidocaine 5 ml; group III: SGB with 2% lidocaine 2.5 ml plus 0.5% bupivacaine 2.5 ml), SGB was performed at the end of surgery. Postoperative pain was assessed with Numeric Rating Scale(NRS) NRS assessment was made 30, 60, 90 min, 2 h, 4 h, 24 h, 48 h after tonsillectomy. Results : Pain scores, after 30 min in group II, III and 60, 90 min in group III were significantly lower than group I(p<0.05). Conclusions : We found SGB was effective in controlling pain after tonsillectomy but further studies are required needs to prolong duration of relief..

Background: Millions of patients with chronic sciatica are still treated with epidural corticosteroids. The efficacy of epidural corticosteroids remains questionable, especially in the failed back surgery syndrome (FBSS). We studied to evaluate outcome for 10 patients with failed back surgery syndrome treated with spinal nerve root block using corticosteroids, hyaluronidase, and local anesthetics. Methods: The affected nerve roots are localized with the help of fluoroscopy and contrast dye. Local anesthetic diluted in 1,500 U hyaluronidase and 40 mg methylprednisolone is injected. A small retrospective pilot group of 10 patients with FBSS was treated. The success rate is evaluated using a visual analogue scale at 1 week and 3 month interval after the last injection. Results: Initially, 7 patients experienced good pain relief; 5 patients suspained pain relief for 3 months. No complications were observed. Conclusions: This technique is worthwhile for patients with FBSS and where epidural fibrosis is suspected to be the pain origin.

This study optimized the mixing ratios of seafood sauce with blue crab for maximal sensory attributes using a response surface methodology with central composite design. It evaluated sensory appeal, nutritional value, and some rheological properties. The optimal formulation appeared to be 252 g of tomato paste, 78 g of chopped garlic, and 519 g of blue crab block; this ratio resulted in a predicted sensory score of 5.7 (on a 7-point scale) for overall acceptability. Addition of blue crab block increased moisture, ash, and protein contents in various sauces, but fat contents were similar in every sauce. Major free amino acids such as glutamic acid, phospho serine, asparagine, and arginine composed about $60\%$ of the total amino acid content. Standard and optimized sauces were red and light yellow, and those color values were significantly higher than in American-style sauces. Optimal viscosity was half the value of American-style sauces; more blue crab block added to the sauce resulted in lower viscosity. Adding this sauce to seafood dishes will likely aid development of flavoring substances.

Scale Invariant Feature Transform (SIFT) generates image features widely used to match objects in different images. Previous work on hardware-based SIFT implementation requires excessive internal memory and hardware logic [1]. In this paper, a new hardware organization is proposed to implement SIFT with less memory and hardware cost than the previous work. To this end, a parallel Gaussian filter bank is adopted to eliminate the buffers that store intermediate results because parallel operations allow all intermediate results available at the same time. Furthermore, the processing order is changed from the raster-scan order to the block-by-block order so that the line buffer size storing the source image is also reduced. These techniques trade the reduction of memory size with a slight increase of the execution time and external memory bandwidth. As a result, the memory size is reduced by 94.4%. The proposed hardware for SIFT implementation includes the Descriptor generation block, which is omitted in the previous work [1]. The addition of the hardwired descriptor generation improves the computation speed by about 30 times when compared with the previous work.

Korea physiographic province is divided into two provinces which is northern Chugaryung graben zone and southern Chugraryung graben zone. Northern Chugraryung is also divided in to Gema block and Kohan block, and southern Chugraryung dividedinto Han block, Yongnam basin and Honam plain. The above mentioned macro geomorophic units is divided, mainly on the geotectonics. The meso geomorphic units is divided, based upon the regional distribution of topographic characteristic that is plateaus, mountains, mountain range, basins and great plain etc. Micro geomorphic units id into a mountain, a hill, a plain, and a lowland, and then it is formed by selfreliant topographic unit. And micro topographic (fan, peneplain, delta, etc) dealt with a characteristics unit. In this article has a disregarded amallest scale that is included flood plait natural levee, back marsh and oxbow lake etc. Accordingly, it shows macro units are meso units are 5, meso units are 53, micro units are 299. A study method of physiographic provincs prefered to aufsteigende and abstergands methoy. How to organically combine topographic factors can be seen in regional distribution of the peculiar topographic characteristics, for charage teristic of topographic makes a study on the topographic of micro unit such understanding as aufsteigende method. At the same time, since it can be studied systematically from marco unit to micro unit like the absteigende methods, I used both methods. And this establishment of physiographic province based on the scientific method depend on the base map of climate classification. Geology, Soil, Biology. I feel confident that it will be used the basic map for land use map, land classification map, study of geomorphology of Korea. And will be used for study of a topographic standard data.

The purpose of this study is to present the direction of the plan to transform the residential complex into a space that can provide an open residential environment that can lead to social communication and exchange without being closed to the urban residential environment, especially in the apartment complex environment, which is becoming more dense. As a result of the Openness analysis of the 'Codan Shinonome Canal Court', the overall accessibility was good in terms of space utilization, and the openness was low in terms of the spatial composition, which is a physical environment due to the dense block type. When looking at the overall openness of the Codan Sinonome complex in terms of analysis by block, the corrected openness index (C.O.I) for all six blocks was 0.245, the corrected accessibility index (C.A.I) was 1.447 and the openness composite index (O.C.I) was assessed at 1.692. This was due to the formation of high-density block-type urban dwellings and the introduction of S-shaped streets and the layout of low-rise urban support facilities and commercial facilities. The Codan Sinonome Canal Court, which is considered an "open city residence," quantitatively confirmed that it embodies macro-space structure and human-scale space environment even in high-precision environments.

Uses of geosynthetics as a reinforcing material for earth structures have ever increased due to their excellent economy. fine external appearance. and easy construction. In the current practice of geosynthetics. however, the lacks of the standardized method of evaluating the soil/geosynthetics friction properties and the inconsistency of conventional design methods develop confusion to the civil engineers. The purpose of site monitoring of the retaining wall reinforced by geogrids was to evaluate the applicability of existing design methods to, and performance of. CHAMSTONE wall system. Full scale field performance during and after construction was monitored by incorporating instrumentation including strain gauges on the geogrid and soil pressure cells. The difference of the reinforcing effects of geosynthetics embedded in the soil will be also investigated by comparing of the line and curve types of retaining wall reinforced by geogrids with block type facings.
