연구개를 포함한 상악골 절제술을 받은 환자는 구강, 비강, 상악동, 비인두를 포함하는 결손을 가질 수 있다. 비강과 구강이 개통되고 불완전한 구개인두폐쇄로 인해 공기 및 음식물이 누출되어 발음 장애, 저작, 연하 기능의 저하가 발생할 수 있고, 안모의 변형으로 환자의 심리상태에 부정적 영향을 줄 수 있다. 구개 폐색장치는 결손 부위 폐쇄를 통해 구강과 비강을 분리시켜 연하, 발음 및 심미적 장애를 개선할 수 있다. 완전 무치악 환자에서 구개 폐색장치는 통상적인 총의치와 같은 유지, 안정을 얻기 어렵기 때문에 결손 부위의 주위조직을 적절히 활용해 변연봉쇄를 얻어야 한다. 또한 hollow type bulb를 통해 보철물의 무게를 감소시켜 유지에 도움을 준다. 본 증례는 우측 편평상피암으로 인하여 상악골 절제술을 받은 63세 남환으로 구강 및 인두부의 기능적 변연형성을 통해 생리적으로 적절한 변연을 갖고, 이중온성법을 사용하여 무게를 감소시킨 보철물을 이용하여 기능적, 심미적 회복을 얻었기에 보고하는 바이다. A patient who went through maxillectomy can have soft palate defects including oronasal fistulas and suffer from dysphagia and dysarthria due to velopharyngeal insufficiency. This defect causes the food to enter nasal cavity and creates hypernasal sound which debilitates a quality of life. An obturator can rehabilitate the substantial oral tissue defects. The maxillary obturator separates the nasopharynx from the oropharynx during speech and deglutition by closing of the defect. For edentulous obturator patient, it is difficult to obtain proper retention due to reduced peripheral sealing. Therefore, the contours of the defects must be used to maximize the retention, stability, and support. Hollow type obturator can improve physiologic function by reducing weight than the traditional obturator. This case report describes a patient with hemi-maxillectomy who recovers mastication, speech, deglutition, and appearance with a maxillary obturator using physiological border molding of the velopharyngeal area and double-processing method.

우유 또는 주스 종이용기를 재활용하여 화장지를 생산하고 있는 제지회사에서 배출되는 제지폐수를 대상으로 주기적 질소 역세척이 가능한 세라믹 정밀여과 시스템을 운전하였다. 제지폐수 재활용을 위해 본 연구에서 7개의 채널이 있는 2 종류의 알루미나 분리막이 사용되었다. 질소 역세척 시간을 40초, 막간압력차 $1.0kg_f/cm^2$, 역세척 압력 $5.0kg_f/cm^2$로 고정하였을 때 $0.4{\mu}m$의 평균기공 크기를 갖고 있는 HC04 알루미나 분리막의 최적 여과시간 간격은 4분으로 $1.0{\mu}m$의 평균기공인 HV10 분리막의 16분보다 짧았다. 여과시간 간격과 역세척 시간을 고정한 상태에서 막간압력차(TMP)의 영향을 살펴본 결과, 높은 TMP 조건에서는 쉽게 막표면에 케이크가 형성되고 막 내부 구조에도 막오염이 발생하기 때문에 낮은 TMP 조건이 막오염 제어에 유리한 것을 알 수 있었다. 그러나 TMP는 폐수처리 여과 시스템에서 구동력이기 때문에, 가장 높은 TMP 조건에서 가장 많은 총여과부피를 얻을 수 있었다. 한편, 다채널 세라믹 분리막을 사용한 정밀여과시스템에서 얻은 투과수는 탁도가 낮기 때문에 제지공정에서 재활용 될 수 있다. The ceramic microfiltration system with periodic $N_2$-back-flushing was operated for treating paper wastewater discharged from a company making toilet papers by recycling milk or juice cartons. Two kinds of alumina membranes with 7 channels used here for recycling paper wastewater. The optimal filtration time interval for HC04 membrane with $0.4{\mu}m$ pore size was lower value of 4 min than 16 min for HC10 with $1.0{\mu}m$ pore size at fixed back-flushing time 40 sec, trans-membrane pressure $1.0kg_f/cm^2$ and back-flushing pressure $5.0kg_f/cm^2$. From the results of TMP effect at fixed filtration time interval and back-flushing time, the lower TMP was better on membrane fouling because high TMP could make easily membrane cake and fouling inside membrane structure. However, we could acquire the highest volume of total permeate at the highest TMP for the reason that TMP was driving force in our filtration system to treat paper wastewater. Then the permeate water of low turbidity was acquired in our microfiltration system using multi channels ceramic membranes, and the treated water could be reused in paper process.

To develop the lake water clean technology by ultrafiltration, the performances of polysulfone and polyacrylonitrile hollow-fiber type modules (Koch Inc.) were investigated using dextran and polyethylene glycol solution, and we found the optimum operation conditions of this ultrafiltration system. Then, the ultrafiltration was operated using water of Gongjee-stream, that was the branch of Euam-lake in Bukhanriver. As the results, the molecular weight cutoffs confirmed in these tests were a little higher than those suggested by the manufacturers, and the optimum transmembrane pressure were 18.5psi in this system. In the ultrafiltration of lake water the rejection rate of turbidity was above 94% and that of BOD, was 24∼50%. However, the rejection rate of TS and TDS were low values, that were 19∼34% and 10∼17%, respectively. Therefore, the suitable module investigated in this study seemed to be polysulfone PM10, which showed the highest rejection rate of BOD_5.

The spiral wound type RO (reverse osmosis) membrane module (BW30-2540) for brackish water showed the high values of salt rejection rate and recovery rate in the primary performance tests. Therefore, it was selected for applying RO membrane process to groundwater treatment to use the industrial water. In the field test of the groundwater the value of permeate rate was almost constant, 29.93L/㎡·hr, and very stable water quality, TDS (total dissolved solids)=10∼20㎎/L. After the operation of the RO membrane process during 750hrs, the membrane was disassembled from the module and investigated to find the membrane fouling and its sources. The components of the fouling layer in the membrane surface were Si, Mn, Fe, Ca and K, which were supposed to be the source of the membrane fouling. And, the insoluble organic materials, i.e. algae, were accumulated on the membrane surface, and the inorganic salt component involved in the fouling layer was 1.2282%.

접촉각 측정방법을 이용한 SiC 단결정의 극성표면 판별에 있어 자연산화막의 영향

박진용,김정곤,김대성,유우식,이원재,Park, Jin Yong,Kim, Jung Gon,Kim, Dae Sung,Yoo, Woo Sik,Lee, Won Jae 한국전기전자재료학회 2020 전기전자재료학회논문지 Vol.33 No.3

The wettability of silicon carbide (SiC) crystal, which has 6H-SiC and 4H-SiC regions prepared using the physical vapor transport (PVT) method, is quantitatively analyzed using dispensed deionized (DI) water droplets. Regardless of the polytypes in SiC, the average of five contact angle measurements showed a difference of about 6° between the Si-face and C-face. The contact angle on the Si-face (C-face) is measured after the removal of the native oxide using BOE (6:1), and revealed a significant decrease of the contact angle from 74.9° (68.4°) to 47.7° (49.3°) and from 75.8° (70.2°) to 51.6° (49.5°) for the 4H-SiC and 6H-SiC regions, respectively. The contact angle of the Si-face recovered over time during room temperature oxidation in air; in contrast, that of the C-face did not recover to the initial value. This study shows that the contact angle is very sensitive to SiC surface polarity, specific surface conditions, and process time. Contact angle measurements are expected to be a rapid way of determining the surface polarity and wettability of SiC crystals.

세라믹 여과 시스템으로 제지폐수 처리시 회수 효율에 대한 물 역세척 시간의 영향

박진용,Park Jin Yong 한국막학회 2004 멤브레인 Vol.14 No.4

본 연구에서는 4종류의 관형 세라믹 정밀 및 한외여과막(탄소 재질)으로 제지공장의 방류수를 물로 주기적 역세척하면서 여과하였을 때, 최적 역세척 시간을 규명하였다. 각 분리막에 대상으로 물 역세척 시간의 영향을 살펴 본 결과, 분리막의 기공이 클수록 길게 역세척 하는 것이 가장 많은 총여과부피, 즉 처리수의 회수 효율이 높기 때문에 가장 효과적이라 할 수 있다. 한편, 180분 동안 여과하면서 초기투과선속에 대한 투과선속의 변화를 살펴본 결과, 정상운전시간이 길수록 막오염이 많이 진행된 상태이므로 역세척 시간을 길게 해주여야만 막오염을 억제하여 높은 투과선속을 유지할 수 있다는 것을 알 수 있었다. 또한, 막오염의 저항 변화 추이를 관찰하여 최적 물역세척 시간을 규명해 보아도, 투과선속의 변화로부터 얻은 최적 역세척 시간과 거의 동일한 결과를 얻을 수 있었다. In this study the discharged wastewater from paper manufacturing plant was filtrated by 4 kinds of tubular ceramic microfiltration and ultrafiltration membranes (carbon material) with periodic water-back-flushing, and we tried to find the optimum back-flushing time (BT). As results of water-BT effect for each ceramic membrane, the longer BT was more effective for a membrane having the larger pore size. And we could acquire the most volume of total permeate and the highest recovery efficiency of purified water, Then, the results of permeate flux vs. initial permeate flux during 180 min's operation showed that the longer BT was more effective for longer filtration time (FT) to obtain the higher permeate flux because membrane fouling proceeded deeply at long FT condition. And the optimum BT that founded from the trends of membrane fouling resistances almost accorded with the optimum BT from the trends of permeate flux, too.
