The authors describe two cases of unusual intracranial metastatic adenoid cystic carcinomas. A 42-year-old woman had a right pariental epidural metastatic mass. presumed hematogenous. spread from a primary tumor in the parotid gland. In second case, a 32-year-old man had a intracranial metastatic adenoid cystic carcinoma mimicking calcified psammomatous meningioma on CT scans. We present these unusual cases with a review of relevant literature and a discussion of possible pathogenesis.

In oriental medicine, man is yang(陽) and woman is eum(陰). Qi(氣) is yang and blood(陽) is eum. Right side is yang and Left side is eum. Man have more Qi than woman. Woman have more blood than man. Right side is man's dominant side and left side is woman's dominant side. Therefore left side is likely to man's affected side and right side is woman's affected side. We researched correlation between sex and affected side in CVA(cerebulovascula accident) and concluded that sex and affected side in CVA is not related.

In most cities, sanitary waste and stormwater are combined in the same sewer system. A significant amount of pollution entering the sewage treatment plant is the-refore from street wash-off during rainstorms. Wastewater flowrates can vary depending on the quantity and quality of the water supply, structure and economic, social, and other characteristics of the community. The flowrates in combined sewer system don't change for low rain intensity, but for high rain intensity increase sharply in rain period. The lower flowrate in mixing commercial and residental area is estimated 1,900㎥/day in combined sewer systems. The average flowrate on morning time in combined sewer systems 6,352㎥/day. The average flowrate in rainfall in combined sewer systems 10,237㎥/day and doubled the flowrate in dry period. The infiltration ratio of interval of two manhole using real measurements is 2.47㎥/m/day. To transform the in-sewer systems, we assumed that the unidentified water is 2 mg/L as BOD. The average BOD loading 114.4 kgBOD/day, the concentration of the real wastewater 56.4 mgBOD/L excluding the unidentified water in influent manhole. The concentration of real wastewater gone down 500m is 45.7 mgBOD/L. We deduce the in-sewer transformation from reducing the loading. The flowrate in separate systems is typically 2-mountain shape, the base-line flowrate is 92.4㎥/day. The BOD loading on rain days in separate sewer system is lower than that of dry days using missing connection between rain pipe and wastewater pipe. 우리나라 대부분의 도시에서는 하수와 우수를 함께 처리하는 합류식 하수관로가 부설되어 있다. 합류식 하수관에서 하수 차집관거의 용량을 초과할 경우 합류식 하수관거에서 배출되는 월류수가 발생하며, 이는 도시하천의 수질에 지대한 영향을 주고 있다. 합류식 관거에 있어서 낮은 강우강도에서는 강우의 유출이 발생하지 않음으로써 하수관거의 유량변화가 나타나지 않으나, 높은 강우강도에서는 강우의 유입으로 높은 유량을 보인다. 생활 및 상업이 혼합되어 있는 지역의 합류식지역에서 최저 유량은 1,900㎥/일로 산정되었으며, 강우기의 평균 유량은 10,237㎥/일로서 건기시의 2배로 나타났다. 500m 간격을 가진 맨홀에서의 기저유량을 중심으로 하여 실질적으로 측정한 불명수량 2.47㎥/m/day로 나타났다. 하수관거를 해석하기 위하여 불명수의 BOD농도를 2mg/L로 가정하였고, 평균 하수관거의 부하량은 114.4kgBOD/day이었으며, 불명수를 제외한 하수관거의 맨홀로 유입된 하수의 농도는 56.4mgBOD/L로 나타났다. 500m 후단에 설치된 맨홀에서 부하량 해석을 실시한 결과는 45.7mgBOD/L로 나타났으며, 이는 하수관거는 생물막의 형태로 작용함으로서 오염물질이 분해되고 있음을 나타낸다. 분류식 지역에서의 유량은 전형적인 쌍봉형을 보여주며, 심야시간대의 기저유량은 92.4㎥/일이며, 강우시와 비강우시의 오염물질 농도를 시간대별로 비교하면, 강우시에 낮은 농도를 보여주고 있는데, 이는 부분적인 오접으로 인하여 농도가 낮아짐을 보여준다.

Nowadays, the parking is a very serious problem almost everyhere. It is even more serious in the parking lot of the high storied apartment. Many parking devices have been developed to solve this problem by increasing the parking capacity within the limited areas. In this study parking devices are considered to obtain the optimum for the capability of carrying the required load and for the minimization of the material usage for the structure. The design of the parking structure studied in this work can readily be applied to many different parking devices.

Actinic lichen planus is a particular subtype of lichen planus with a distinct photodistribution. This disease has been variously named lichen planus in subtropical countries, such as lichen planus subtropicus annularis, lichen planus tropicus, summertime actinic lichenoid eruption, and lichenoid melanodermatitis. It is a disorder seen most frequently in Africa, the Middle East, and the Indian subcontinent, favoring Asiana. This disease presents in the spring or summer and is frequently quiescent during the winter. A 61-year-old man with unusual lichenoid photosensitive eruption is presented. The lesions developed during the late spring, appearing on both dorsa of hands, wrists, and lower legs. We report a case of actinic lichen planus with a review of the literature.

본 연구는 무연탄으로 활성탄을 제조할 경우 성형이 세공특성에 미치는 효과를 고찰한 것이다. 3가지 다른 방법으로 활성탄(파쇄형 활성탄, 압축성형 활성탄, 압축성형 활성탄)을 제조하여 특성을 비교했다. 이중에서 25%의 콜타르와 7%의 물을 혼합하여 압출 성형한 활성탄이 비표면적, 세공부피, 그리고 경도에서 가장 좋은 물성을 나타내었다. 압축 및 압출 성형체의 표면은 무연탄 원탄과는 달리 무연탄 분말이 바인더와 혼합되어 있으므로 매우 거친 상태를 나타내었고, 활성화시 거칠게 형성되어 있는 입자사이로 활성화제인 수증기가 쉽게 침투하여 많은 세공을 형성시킴을 알 수 있었다. 이렇게 형성된 세공을 통해 수증기 활성화반응이 잘 일어나 직경 3,000-50,000Å 범위의 거대세공이 발달하였다. 파쇄형 활성탄에 비해 약 2배의 거대세공(macropore)부피를 가지고 있었으며 경도도 30%에서 95% 이상으로 상승되었다. This study was to investigate the effect of granulation process on pore characteristics in manufacturing anthracitebased activated carbons. The activated carbons were made by three different methods to compare characteristics: the crushed activated carbon, the compressed activated carbon, and the extruded activated carbon. Among these activated carbons, the extruded activated carbon using a binder that consists of 25% coal tar and 7% water showed the best characteristics in specific surface area, pore volume, and hardness. Since the compressed and the extruded substances had coarser surfaces than a raw material, steam could penetrate easily through particles and produce macropores especially in the diameter ranges of 3,000-50,000Å during activation process. The extruded activated carbon showed about twice more macropore volumes than the crushed activated carbon and the hardness was increased from 30% up to 95%.

The size of minimum order stream has a very sensitive effect on runoff analysis model using the divergence characteristic of stream. Therefore, in this study, the threshold area of minimum order stream has been examined the change characteristic of topographical parameters. The subject basin of the research was the upper basin of the Kumho water gage station which is located in the middle of the Kumho river. The 1:25,000 numerical geography which was constructed 10×lOm mesh was used. The range of investigation of topographical parameters are number of stream order, length, area, slope, basin relief, sinuosity ratio, drainage density and total stream length etc. It was found from the result of analysis that the threshold value of minimum order stream has a very big effect on topographical parameters of basin. It was found that the threshold area of minimum ord er stream revealed under 0.10km². Furthermore, the parameters showed a serious change except for over 0.10km².

In order to evaluate the effect of poloxamer 407 content on the dissolution profiles of pellets, diltiazem HCl (DTL) core pellets were prepared with poloxamer 407 (50∼90% w/w, with lactose as filler) using an extruder and a spheronizer. Any possible interaction between the drug and excipients was evaluated using DSC, IR and TLC. Dissolution tests were performed using USP basket method. In addition, scanning electron micrograph was performed to examine the surface roughness and cross sections. The release of DTL from the core pellets was decreased with increasing poloxamer 407 content. Cracks appeared on the surface of the core pellets with increasing the poloxamer 407 content, which may play a role on the retardation of the release of DTL from core pellets. There was no any significant interaction between the drug and excipients employed to prepare the core pellets.

Activated carbons were prepared from Korean coal by steam activation in this study. The variation of pore structure of the activated carbons were investigated according to different carbonization temperatures. Yield, surface area, pore volume and pore structure of this activated carbon were compared with those of activated carbon prepared without carbonization. The investigated carbonization temperature ranged from 700℃ to 1,000℃. Carbonization was carried out in nitrogen atmosphere for 70 minutes and activation was performed by steam at 950℃ for 210 minutes. Surface area and pore volume of the resulting activated carbons increased with carbonization temperature. Also pore volume increased by 20% compared to the activated carbon without carbonization. Especially, in mesopore region, the activated carbon carbonized at 900℃ had more pores by 60% than that of activated carbon carbonized at other temperature.
