심미와 기능이 조화를 이루는 총의치 제작을 위해서는 상하악 관계를 정확히 기록하는 것이 필수적이다. 고딕아치 묘기법은 하악의 운동을 시각적으로 보여주며, 정확하고 반복재현성 있는 중심위를 확립하는데 유용하다. 또한, 고도의 치조제 흡수를 갖는 환자에서는 총의치의 적절한 유지 및 안정을 얻기가 어려운데, 이런 경우 환자의 생리적인 동작으로 변연을 형성하여 의치상연 주위가 가동점막으로 봉쇄되도록 하는 폐구 인상법이 유용할 수 있다. 본 증례에서는 우측 하악과두골절 병력과 고도의 하악 치조제 흡수를 보이는 환자에서 폐구인상법과 고딕아치 묘기법을 이용한 총의치로 수복하였고 만족할 만한 결과를 얻어 보고하는 바이다. It is essential to record maxillomandibular relationship accurately for the harmony of esthetic and function in complete denture. Gothic arch tracing visually demonstrates the movement of the mandible, and is useful to establish accurate and reproducible centric relation. Proper retention and stability of complete denture in patients with severe alveolar bone resorption is difficult to attain. In such case, the closed mouth impression technique might be recommended. The denture border and impression are determined by patient's physiologic movement in the closed mouth impression technique. And, denture peripheral border is entirely closed with oral mucous membrane. This report presents satisfactory complete denture restoration using closed mouth impression technique and gothic arch tracing in patients with mandibular condyle fracture and severe absorption of mandibular alveolar ridge.

본 연구는 수중에 용해된 인과 질소 제거효과를 갖는 세라믹소재를 개발하기 위하여 수행되었다. 감람석을 이용한 인의 제거효과는 “이”와 “최”의 연구에서 수행된바 있으며, 제올라이트를 이용한 질소제거에 관한 연구는 국내외적으로 많이 수행되어 왔다. 본 연구에서는 감람석(Olivine)과 제올라이트(Zeolite)를 서로 다른 부피 혼합비에 따라 혼합한 후 소성하여 얻어진 세라믹을 이용하여 수중에 용해된 총인(Total-Phosphorus)과 총질소(Total-Nitrogen)의 제거효과를 회분식 실험(batch reactor system)을 통해 분석하였다. 연구결과 총인의 경우 감람석과 제올라이트의 부피 혼합비가 1:2의 경우 최고의 제거효율을 보였으며, 시험개시 30분 일 때 96.0%, 4시간일 때 95.1% 의 인이 제거되었다. 총질소의 경우 감람석과 제올라이트가 1:6일 때 시험개시 30분일 때 93.6%, 4시간일 때 97.4%의 질소가 제거되었다. This study was performed to develop ceramic material to be able to eliminate phosphorus and nitrogen in water. Olivine was found to remove phosphorus in aqueous phase, which was demonstrated by Lee and Choi.1) The nitrogen removal using zeolite has been demonstrated by many researchers.2,3) Hence, utilization of mixed-typed material of Olivine and Zeolite is expected to achieve simultaneous elimination of phosphorus and nitrogen in water. In this study, the removal efficiencies of T-P(Total phosphorus) and T-N(Total nitrogen) were investigated using ceramic material in batch reactor system, which was produced by incinerating after mixing Olivine and Zeolite with different ratio. The highest removal efficiency of phosphorus was achieved under the condition of 1: 2 mixing volume ratio of Olivine to Zeolite. The phosphorus of 93.6% and 97.4% (as T-P) was removed for 0.5hr and 4hr, respectively. For the nitrogen, the nitrogen removal efficiencies of 93.6% and 97.4% (as T-N) were obtained under the condition of 1:6 mixing volume ratio of Olivine and Zeolite.

Laboratory flume experiments to investigate the characteristics of the flows and local scour around cicular shapes of bridge pier in a curved channel are performed. For the various discharge conditions, the maximum transverse bed slope is generated at the location of 150° in a curved channel. The scour depth due to a collar is about 40% of the scour depth without collar in a straight course of the flume shile it is about 44% of the scour depth without collar at the location of 150° in a curved channel. Also, when the collar is placed at the 0.1 times of water depth, the reduction of scour depth is very effective in a curved channel. As a result of using a non-symmetry collar, the ratio of non-symmerty width is 1 : 3 and the 8 degree of angle of attack are the most effective to reduce the maximum local scour depth.

Rational method known as the first rainfall-runoff model has been widely used by many engineers because of its simplicity and convenience. However, rational method is of difficulty in obtaining the accurate value of rainfall-runoff because it contains hydrological parameters such as drainage area, rainfall intensity, time of concentration, or runoff coefficient. A number of researchers paid much attention to deriving the runoff coefficient because it is evaluated as an pivotal parameter that relates the correlation of rainfall with runoff. A variety of formula and tables have been provided for the appropriate runoff coefficient. The limited corrected runoff coefficient was verified. Selma stream was chosen as the experimental catchment because it can represent the area with relatively small size of region and with the developed stage-discharge curve. In addition, the existing runoff coefficient exhibits relatively large deviation for natural river basin. Based on the results of the application of corrected runoff coefficient to the estimation of stream flow throughout the precedent rainfall phenomena of Selma stream area, it was found that the range of presented runoff coefficient for the domestic woodland area was underestimated.

In this paper, a class J amplifier with high efficiency is designed. As a method of improving the efficiency of a power amplifier, many methods of shorting high-order parasitic components are used. Class F amplifiers short the odd-order high frequency components, and Class E amplifiers short the even-order high frequencies. Class J amplifiers are short circuits of other components, leaving only the secondary or tertiary high frequency components of class E and class F amplifiers. The measured results of the designed class J amplifier showed that the maximum output power was 31.5dBm, the gain was 16.5dB, and the minimum output power was 29.8dBm when the input power was 15dBm. Maximum drain efficiency is 75.49% at 2.95GHz and minimum drain 1.6GHz is 55.68%. In the 1.6GHz to 3.2GHz frequency band, the average gain is 15.35dB and the average drain efficiency is 66%
