일상적인 상황에서 방위산업에 관련된 물류관리의 중요성은 일반 산업에 비하여 크지 않으나, 예외적인 상황이 발생했을 때에는 신속한 해결책을 찾아내어 문제를 해결하지 않으면 국방에 있어서 전략적 공백으로 이어질 수 있다. 그러므로 예외상황에 대한 신속한 대비책을 구축하는 것이 필요하며 본 논문에서는 업무절차관리(BPMS) 시스템을 도입하여 물류 프로세스의 지속적인 개혁 및 개선을 유도한다. 이를 위하여 프로세스 저장소의 사용을 제안하며, 예외발생시 신속한 처리방안을 검색하기 위한 검색트리의 사용방법론을 제시한다. 획일적인 업무처리가 강조되는 군사작전 및 방위산업의 환경 하에서 예외상황의 처리를 위한 효율적 장치를 마련하는 것은 방산운용의 측면에서 매우 중요하다. 본 논문에서는 특히 지식경영의 관점에서 예외처리 시 생성되는 새로운 프로세스 지식을 프로세스 저장소(process repository)에 저장하고, 예외발생시 이 문제의 해결에 적합한 프로세스를 저장소에서 신속하게 검색하는 데 활용할 수 있는 검색트리의 생성과 활용에 대한 방법론을 연구하였다. 검색트리의 생성과 활용을 위하여 ‘상황변수’와 ‘의사결정변수’의 개념을 새로 도입함으로써 문제의 상황을 체계적으로 기술하고 저장 및 검색하는 방편을 제시하였으며, 예외상황의 인식능력(context awareness)을 제고시켰다. 정보의 엔트로피를 기초로 한 C5.0 알고리즘을 적용하여 정보이득을 최대화하는 검색트리를 생성하는 방법을 제시하였다.

Crude saponin(100g) were obtained by extracting the radix(5kg) of Scrophalariae koraiensis Nakai. Crude saponin were positive in the Liebermann-Burchard test. We observed 5 sports by TLC using BuOH saturated with H_2O : ethyl acetate : water(4:1:5, upper phase) as solvent and 1% Ce(SO_4)_2 in 10% H_2SO_4 as a color former. We divided into 3 fractions by common column chromatography using BuOH saturated with H_2O : ethylacetate : water(4:1:5, upper phase) as solvent.

A sewage treatment plant which has been operated by the treatment process of conventional activated sludge process and its optimal operating factors depends on a condition of its design and environment. This study was carried out by experiments to exhibit optimal operating factors of the Sludge process. The sewage was inflowed regularly but in winter. The concentration of Inflow water appeared that of spring/summer is higher than that of autumn/winter. The removal rate of BOD/SS sppeared in the order of summer>spring>autumn>winter. MLSS was maintained high in winter/spring, low in summer/autumn, because it changes according to the temperature of the aeration tank and pollutional concentration of the inflow water. The optimal operating factors can improve the process efficiency and operate easily at the sewage treatment plant. The results of this study were summarized as follow; 1) In the winter, it has been measured that DO is 1.5mg/ℓ, MLSS is 2,191mg/ℓ, SV?? Is 15%, a load of BOD-SS(F/M ratio) is 0.16, SVI is 68, SRT is 10 day, the return rate of sludge is 44%. 2) In the spring, it has been measured that DO is 2.3mg/ℓ, MLSS is 2,047mg/ℓ, SV??is 21%, a load of BOD-SS(F/M ratio) is 0.15, SVI is 106, SRT is 6 day, the return rate of sludge is 37%. 3)In the summer, it has been measured that DO is 0.8mg/ℓ, MLSS is 1,653mg/ℓ, SV?? is 8.5%, a load of BOD-SS(F/M ratio) is 0.3, SVI is 51.6, SRT is 4 day, the return rate of sludge is 33%. 4) In the autumn, it has been measured that DO is 0.7mg/ℓ, MLSS is 1,560mg/ℓ, SV?? is 9.7%, a load of BOD-SS(F/M ratio) is 0.17, SVI is 62, SRT is 7.91 day, the return rate of sludge is 38%.

IPOW 기술은 파장이 갖는 특성으로 인하여 여러 가지 제약 사항을 갖고 있어 기존에 개발된 MPLS 기술을 효과적으로 적용하기 위해서는 WDM의 특성을 잘 분석하여 적용하여야 한다. 본 논문에서는 현재 IETF를 중심으로 연구중인 MPLambdaS 개념을 기초로 하여 광 인터넷의 진화를 고려한 구조적인 접근 방법을 연구한다. MPLS 도메인과 MPLambdaS 도메인간에 연동을 고려하여 전자적인 다수의 LSP를 광 LSP로 모으는 레이블 스택 개념을 이용한 Lambda LSP Tunneling 기술을 적용하여 전자적인 MPLS와 광 MPLambdaS 간의 연동 방안을 제안하고 이를 지원하는 Edge Optical LSR의 구조를 제안한다.

Purpose : To assess the diagnostic accuracy and value in an imaging technique field through the comparison of cone beam computed tomography and conventional panoramic radiography in assessing the topographic relationship between the mandibular canal and impacted third molars. Materials and Methods : Participants consisted of 100 patients offered the images through cone beam computed tomography and panoramic radiography. PSR-9000 Dental CT system (Asahi Roentgen Ind. Co., Ltd, Japan) was used as the unit of cone beam computed tomography. CE-II (Asahi Roentgen Ind. Co., Ltd, Japan) and Pro Max (Planmeca Oy, Finland) were used as the unit of panoramic radiography. The images obtained through panoramic radiography were classified into 3 types according to the distance between mandibular canal and root of mandibular third molar. And they were classified into 4 types according to the proximity of radiographic feature. The images obtained through cone beam computed tomography based on the classification above were classified into 4 types according to the location between the mandibular canal and the root and were analyzed. And they were classified into buccal, inferior, lingual, and between roots, according to the location between mandibular canal and root. The data were statistically analyzed and estimated by χ²-test. Results : 1. There was no statistical significance according to 3 types (type l, type ll, type lll) through CBCT. 2. The results of 4 types (type A, type B, type C, type D) through CBCT were as high prevalence of CBCT 1 in type A, CBCT 2 in type B, CBCT 3 in type C, and CBCT1 in type D and those of which showed statistical significance (P value=0.03). 3. The results according to location between mandibular canal and root through CBCT recorded each 49, 25, 17, 9 as buccal, inferior, lingual, between roots. Conclusion : When estimating the mandibular canal and the roots through the panoramic radiography, it could be difficult to drive the views of which this estimation was considerable. Thus it is required to have an accurate diagnostic approaching through CBCT that could estimate the location between mandibular canal and roots.

The use of computed tomography for dental procedures has increased recently. Cone beam computed tomography (CBCT) systems have been designed for imaging hard tissues of the dentomaxillofacial region. CBCT is capable of providing high resolution in images of high diagnostic quality. This technology allows for 3-dimensional representation of the dentomaxillofacial skeleton with minimal distortion, but at lower equipment cost, simpler image acquisition and lower patient dose. Because this technology produces images with isotropic sub-millimeter spatial resolution, it is ideally suited for dedicated dentomaxillofacial imaging. In this paper, we provide a brief overview of cone beam scanning technology and compare it with the fan beam scanning used in conventional CT and the basic principles of currently available CBCT systems.

A Computer program for the precombustion chamber type 4 cycle C.I.engine using two-zone model and quasi-steady model has been developed. Comparing with experimental results, the calculated results have about 10% of deviation. Through the numerical analysis, the direction of optimum engine design condition can be obtained as follows; 1) From the numerical solution, the optimal driving points of experimental engine are as follows. Engine speed is 2500 - 3000rpm and the injection timing is 15-20。BTDC, When the economy of fuel is considered, and when the engine is driven under 2100 rpm and fuel is injectioned at 25。BTDC, the maximum output can be obtained. 2) The maximum cylinder pressure increase about 3% at every 400 rpm, and increase about 20% whenever the injection time is advanced at 5 degrees. 3) The volumetric efficiency decrease about 9% at every 400rpm.

This study was to investigate the cause of the color and turbidity in a small-scale water treatment plant using lakes water as water supply source. Water qualities in aqueducts, in depth of the lakes and in each process were measured. And effects of prechlorination on each unit operation in the water treatment, especially on iron and manganese removal, were studied. The concentration of iron and manganese was 0.13, 0.08 mg/L in the surface water and 1.93 and 0.433 mg/L in 15 m depth of the lake. Higher iron concentration of the inlet was measured to 5.35 mg/L which was caused by the steel aqueduct corrosion. The optimun coagulation dosages of Poly Aluminum Chloride(PAC) and Liquid Aluminum Sulfate (LAS) were 17.5 mg/L and 35 mg/L. Pretreatmnet of raw water with CaCOl improved the removal efficiencies of iron and manganes. However, more efficient method for removing iron and manganes was required.
