Angioneurotic edema is rarely seen in dental practice and manifested by acute attacks of swelling of the extremities, face, airway, or abdominal visera, occuring spontaneously and suddenly or secondary to trauma. Two types are recognized : hereditary and nonhereditary. Prophylatic therapy may be used by fresh frozen plasma or antifibrinolytic agents in hereditary type. Good supportive care for acute attacks, together with a knowledge of course of the disease, can prevent asphyxiation from airway obstruction. A case of acute angioneurotic edema of the facial area in a 19-year-old man is presented in conjunction with a review of the literature. Angioneurotic edema attacks him acutely after the extraction of the lower, right 3rd molar.

Gas permeation behavior was examined for asymmetric cellulose acetate membrane prepared by changing the acetone evaporation time and drying solvent. By changing the acetone evaporation time, the gas permeation rate decreased for the first 2 minutes and then increased gradually for the membrane of i-PrOH exchange drying. Gas permeation rate was in the order of He>N₂>O₂ and separation factor was about 1.9 for the membrane of 9 minute acetone evaporation. The permeation mechanism appears to be the combination of Knudsen flow and viscous flow. The effect of Knudsen flow was increased with acetone evaporation time, while the effect of viscous flow increased for the membrane of EtOH exchange drying.

This paper studies the schemes to apply the Simulated Annealing algorithm that is used as an optimization stchnique for neural Network as a technique for finding the optimal design of experiments and compares this implemented results with those of Branch and Bound algorithm which completely gurarantees the optimality in order to evaluate their performance. In this comparison, D-optimality is used as a criterion for optimization.

A basic fluidelastic excitation mechanism causes large whirling vibrations of tubes in model arrays when the flow velocity exceeds a critical value. The nondimensional critical velocity is ?? where ?? the threshold instability constant is a function of the tube pattern and spacing. In this paper, ?? were given that were obtained from experiment on single-row tube array in uniform crossflow. The vibration characteristics of tube array were described as a function of flow velocity.

The relation between local self-government and democracy is inseparable. Because local self-government can make contribution to securing democracy of self-rule. And the local self-government can be actually secured without the establishment of sound local finance. The autonomous local finance is a prerequisite condition for the local self-goverment as a basis of democracy. But Korean local self-government has not yet grown up enough and has been stagemet One of the more restrictive factors in the development of self-government is generally recognized to be insufficient local finance. Without sufficient financial resource, local self-government is not only a normal autonomy but is unable to carry out any functions substantial of self-government. The purpose of this study is find out ①actual condition through case study in Busan ②alternatives to enlarge the present condition of the local finance in Korea. By the result of analysis of the local finance in Korea, the important problem has discovered that the local finance in Korea is too scanty to meet the rapidly increasing public needs and to cope with enlarging problems. And many institutional and practical problems have discovered. These are as follows. 1)scantiness of the local finance. 2)inelasticity of the local finance. 3)poorness of the independent funding resources. 4)problems the local financial adjustment system. To reform these problems of local finance, this study proposed some alternative policies. Although these alternatives can not be satisfactory solutions, they can provide some suggeston and references for the local finance reform. 1)The proposals for reform of the local tax administration are as follows; (1)to optimize tax sources distribution adjuration national tax and local tax. (2)to adjust tax rates of local taxes. (3)to develop the new types of local tax sources. 2)To raise the non-tax revenue. 3)Rational management of local financial adjustment systems.(local share tax and national subsidies) 4)To introduce a local transfer tax system in order to improve regional disparity and promore long-term stability of local finance. 5)An active application of local borrowing and introduction of regional development fund. 6)An active application of the local public enterprises and third sector.
이온주입법에 의해 실리카에 형성한 실리콘 나노결정의 구조적 특성연구

Si nanocrystals have been fabricated in fused silica by ion-implantation to doses of 6×10^(16) to 6×10^(17)cm^(-2) and subsequent high temperature annealing and their structural properties have been studied by Raman scattering and high resolution transmission electron microscopy(HRTEM). By fitting experimental Raman spectra, it is obtained that both crystallite size and crystal fraction increase with increasing the implant dose, also confirmed by HRTEM. Higher-dose implantation induces shifts of Raman peak to lower frequency and the discrepancy of this downward shift with the Phonon confinement model may be attributed mainly to the stress exerted on Si nanocrystals due to the existence of the fused silica. The Raman-line shift due to stress effects increases from negative to positive values with increasing the dose, indicating a gradual transformation of compressive to tensile stress.

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.

This study was performed to evaluate the actual temperature rise on the surface of Buchanan plugger using thermocouple. The heat carrier system 'System B Heatsource'(Model 1005, Analytic Technologies, Redmond, WA, USA) and the Buchanan pluggers of F, FM, M and ML sizes are used for this study. The temperature was set to 200℃ on digital display and the power level on it was set to 10. Five thermocouples were placed in direct contact with the surface of each size of Buchanan's pluggers at 1 mm increments from the tip to the 4 mm length of shank. The heat control spring was touched for 5 seconds, and temperature rise on the surface of the pluggers were measured at 1 sec intervals for more than 5 seconds with an accuracy of 0.01 using Data Logger. The data were statistically analyzed by one-way ANOVA. The results were as follows. 1. The position at which the temperature peaked was approximately at 1~2 mm far from the tip of Buchanan plugger (p<0.01). 2. The peak temperature was 215.25±2.28℃ in F plugger, 185.94±2.19℃ in FM plugger, 169.51±9.12℃ in M plugger, and 160.79±1.27℃ in ML plugger and the peak temperature was highest in F plugger and followed by, in descending order, FM plugger, M plugger. ML plugger showed the lowest peak temperature (p<0.01). 3. The temperature on the pluggers was decreased with the increase of touching time. This results suggest that the actual temperature on the surface of the pluggers dose not correlate well with the temperature set on digital display. Heat concentrates around the up. The larger plugger reveals lower temperature rise relatively.

The study considered various procedures for the application of chitosan on cotton fabric, the effect of the biopolymer on the exhaustion and dyeing efficiency. The application of the polycationic biopolymer chitosan to a cotton fabric allows an increase in dye exhaustion leading to a reduction in reactive dyestuff consumption, and less dye in waste waters. Chitosan boosts dyeing efficiency.

한글대장경의 전산화 및 검색 시스템 개발은 세계에 우리 문화의 우수성을 널리 알리고, 우리 문화유산에 대한 국민적 관심을 높이며 해당 분야에 대한 효과적인 연구를 지원하기 위해 반드시 필요하다. 한글대장경은 고려대장경의 번역본으로 주로 한글로 기록되어 있지만, 원문의 이해를 돕기 위해서 다양한 한자가 사용되고 있다. 이러한 한자들은 본자(本字)와 뜻은 같지만 모양이 틀린 이체자(異體字)및 오자(誤字)나 탈자(脫字)로 간주되는 파자(破字) 등을 포함하고 있으므로 입력이나 저장 뿐 아니라 검색 관점에서도 여러 가지 문제점을 갖는다. 또한 인터넷이 널리 보급되면서 인터넷을 통한 문헌 검색이 증가하였지만 기존의 문헌 검색 시스템은 용어 검색, 색인 검색 등과 같은 단순한 검색만을 지원하기 때문에 사용자의 다양한 검색 요구를 충족시키기가 어려웠다. 본 연구에서는 한글대장경의 효과적인 입력과 저장을 위해 유니코드(unicode)를 사용하였고, 효율적인 검색을 위해 문서 구조를 XML로 정의하였으며, 결과내 검색과 히스토리 검색 등과 같은 다양한 검색 방법을 지원하는 웹 기반 한글 대장경 검색 시스템을 개발하였다.
