본 논문에서는 AR 보드 게임을 위한 FTIR 방식의 멀티 터치 스크린 시스템을 제안한다. 기존 보드 게임은 카드의 정보나 위치등 다양한 정보를 보여주면서 사용자와의 상호작용에 있어서 버튼과 같은 단순한 형태의 입력을 요구한다. 이러한 낮은 상호작용을 보완하기 위해서 다양한 형태의 패턴 등을 입력할 수 있는 멀티 터치 스크린 시스템을 적용한 텐저블 사용자 인터페이스를 제공하여 사용자로 하여금 더 많은 상호작용과 높은 몰입감을 제공하고자 한다. 본 논문에서 제안하는 시스템은 다음과 같이 구성된다. 먼저, 텐저블 사용자 인터페이스를 위해서 Jefferson Y. Han이 제안한 시스템과 유사한 형태의 FTIR 방식의 멀티 터치 스크린을 테이블 탑 형태로 제작한다. 또한, 스크린 위의 카드를 인식하기 위해서 특정한 모양의 패턴을 적용한 적외선 반사지를 카드에 입힌 후, DI 방식을 사용하여 카드의 고유한 정보를 인식할 수 있도록 하였다. 마지막으로 사용자에게 인터페이스의 확장뿐만 아니라 시각적으로 높은 몰입감을 제공하기 위해 Bimber가 제안한 Virtual Showcase를 적용하였다. 이러한 시스템을 통해 사용자는 이전의 단조로운 형태의 게임에서 벗어나 훨씬 다양하고 높은 몰입감을 즐길 수 있게 되었다.

최근 국가기간 철도망의 도심지 통과시 민원 및 환경, 기존 노선과의 접속 등의 이유로 구조물 근접, 하저, 퇴적층~경암의 복합지반 등 점점 더 가혹한 현장조건에서도 터널공법의 적용이 요구되어 지고 있으며, 이들 조건에서도 안전하게 시공이 가능한 쉴드(Shield) TBM에 대한 적용이 증가하고 있다. 본 고에서는 대곡~소사 복선전철 민간투자시설사업 구간 중 한강 하저를 횡단하는 철도 쉴드(Shield) TBM 터널 설계시 주요 고려사항에 대해 기술하고자 한다. 특히, 하저구간 통과시의 고수압 조건과 한강 하류지역의 지질학적 특성으로 인한 풍화대 심도가 불규칙한 복합지반, 다수의 단층파쇄대, 퇴적층 등의 불량한 지반조건을 통과하기 위한 쉴드 TBM의 검토사항과 터널안정성 확보를 위한 주요 설계 방안을 중점적으로 다루고자 한다. Recently, despite of the harsh conditions such as adjacent structures, underwater tunnel, and complex grounds, tunnel construction has been performed inevitably in underground metropolitan area because of civil complaint, environment and connection with existing railway. Thus, it has been increasingly demanded to be constructed by Shield TBM excavation method that can be a safe way under these adverse conditions. In this paper, we would like to introduce the major considerations about the shield tunnel design for passing through under the Han-River among the BTL Project of double-track electrification in the Deagok~Sosa section. Especially, Focus on key design strategies are discussed in Shield TBM and securing the tunnel stability for passing through under the river, such as high water pressure, complexity ground, many fault fractured zone, sedimentary layer

Puff pastry의 제조 공정에서 pastry 마가린 함량과 적층 수의 변화가 제품의 수분 함량, 굽기 손실, 부피, vapor action 등에 미치는 영향을 조사하였다. Pastry 마가린 함량이 90%로 동일하고 적층 수가 27결일 경우 10.8±0.6%의 수분 함량을 나타냈으며, 1024결일 경우 16.7±0.3%로 적층 수가 증가할수록 제품의 수분함량은 증가 하는 경향을 보였다. 적층 수를 256결로 동일하게 하고, pastry 마가린 함량이 50%일 경우는 17.3±0.5%로 나타났으며, 130%에서는 7.5±0.2%로 pastry 마가린 함량이 증가할수록 제품의 수분 함량은 감소하였다. Pastry 마가린 함량을 70%로 동일하게 했을 때 굽기 손실의 변화는 27결일 경우 25.0±0.7%로 나타났으며, 1024결일경우엔 18.8±0.6^로 나타나 적층 수가 증가할수록 제품의 굽기 손실은 감소하는 경향을 보였다. 적층 수를 27결로 동일하게 한 경우에서는 pastry 마가린 함량이 90%일 때 25.4±0.4%의 굽기 손실이 발생하였으며, 110%에서 26.9±0.4%로 굽기 손실이 가장 높게 나타났다. Pastry 마가린 함량이 130%이고 적층수가 81결일 때에 21.87±0.79㎖/g로 최대의 부피를 나타내었다. 또한 vapor action의 크기는 9.15㎜가 pastry 마가린 함량 110%, 적층 수 256결에서 8.25±0.50개로 가장 많이 나타났다. This study was carried out to investigate the effect of pastry margarine content and number of layers on moisture content, baking loss. specific loaf volume and the vapor action in the manufacturing process of puff pastry. As the number of layers of the puff pastry increased the moisture content of the products slightly increased. And the moisture contents of the products decreased, as the pastry margarine contents of the puff pastry increased in the same number of layers. The baking loss of the products tended to decrease as the number of layers increased. On the other hand, as the pastry margarine contents of the puff pastry increased, the baking loss of the product increased. When the pastry margarine content in puff pastries became 130%, 81 layers provided the maximum specific loaf volumes 21.62±0.79 ㎖/g of puff pastries. When 110% of margarine and 256 layers were applied for preparation of puff pastry, the number of vapor action was 8.25±0.50 with the vapor action size of 9-15 ㎜.

The purpose of this study was evaluate immunohistochemical observation to epidermal growth factor of the effect of duct ligation of mouse submandibular gland. Fifty two mice were aging 3 months old, devided into experimental group(36 mice) and control group (16 mice). Under general anesthesia, 36 animals were ligated in left side duct of submandibular gland. Experimental animals were sacrificed consecutively on 1st, 6th, 12th hours and 1st, 2nd, 3rd, 5th, 7th, 14th day after duct ligation. These specimens fixed with formalin and sectioned in paraffin. Subsequently were stained with H-E and immunohistochemistry to observe epidermal growth factor. The results were as follows ; 1. After duct ligation, the acinar cells were atrophied and disappeared and granular convoluted tubule cells in which cytoplasm atrophied and granules reduced, degenerated duct-like structure. 2. With the time lapse, epidermal growth factor in cytoplasm of granular convoluted tubule cells reduced with change of features of granular convoluted tubule. 3. From 7th day after duct ligation, there are suggested that duct-like structure were originated from granular convoluted tubule and these were regressive changes by secretory disturbance.

Relationship between growth rate and wood properties was investigated by water absorption and hygroscopic properties with Alnus glutinosa L. from 4 different origin of seed (Bulgary, Italy, United Kindom, Yugoslavia). In cross sectional water absorption. there was difference among different origin of seed and higher growth rate led to higher water absorption as 0.62~2.82 g/cm2 ranges with average 1.81 g/cm2. In equilibrium moisture content (EMC) at temperature 40oC relative humidity(RH) 75%, there was difference among different origin of seed and higher growth rate led to higher EMC as 12.32 ~13.16% ranges with average 12.65%. EMC at temperature 40 RH 90%, there was difference among different origin of seed and higher growth rate led to higher EMC as 29.01~34.15% ranges with average 30.32%. In cross sectional moisture absorption at 24 h treatment. there was no difference among different origin of seed and different growth rate as 0.031~0.041% ranges with average 0.036 g/cm2

Alkoxysilanes were synthesized by me alcoholysis of trichbromethyhilanc having trifunctional group with corresponding alcohols under sodium alkoxide or HCl acceptor. The yields of the products were more than 80%. It was found that the rate of the hydrolysis of ethoxysilane was faster than methoxysilane. Hexamethyldisilazanes were synthesized by the reaction of chlorotrimethylsilane with ammonia gas or ammonium liquid solution. The yields of the products were 86% and 26% respectively. As the results of hydrolysis of disilazanes prepared under acidic, neutral, and alkali solutions, the rate of the hydrolysis was increased with the order of alkali, neutral, and acidic solution. After synthesizing α,ω-dichloromethylsiloxane by the reaction of diethoxydimethylsilane with dimethyldichlorosilane, α,ω-dichloromethylsiloxanol with terminal hydroxyl group was prepared by the hydrolysis of the product. p-Phenylene-bis-dimethylchlorosilane was prepared through Grignard reaction of p-dibromobenzene with dimethyldichlorosilane, and then p-phenylene-bis-dimethyltydroxysilane was synthesized by the hydrolysis of p-phenylene-bis-dimethylchlorosilane. α,ω-dichloromethylsiloxane

The tunneling barrier is crucial to the overall performance in magnetic tunnel junction. We have suggested a new formation method for the tunnel barrier, which has utilized pseudo atomic layer deposition with sputtering (PALDS). As is well known, all metallic thin films oxidize more or less under atmospheric conditions. With using this property of metallic thin films, we have prepared tunnel barrier by sputtering metallic thin film and exposing it to the oxygen ambience. From transmission electron microscopy (TEM) observation, the formed tunnel barrier has been confirmed to have clear and good interface between magnetic layers and tunnel barrier. From atomic force microscopy (AFM) observation, it has been also confirmed to have low surface roughness. The TMR MRAM cell manufactured using PALDS method has been shown to exhibit typical tunnel resistance of 86 KΩ·μm^2 and TMR ratio of about 40%. The 40% of MR is quite large. It is considered that this value is geometrically enhanced magnetoresistance due to the low junction resistance of MTJ.
