도시와 산업의 급속한 성장에 따라 폐기물의 발생량이 급증하고 있어 그 처리가 중요한 문제로 대두되고 있다. 현재 폐기물 처리에 대한 국내의 정책방향은 폐기물의 발생 자체를 억제하고, 기 발생된 폐기물은 적절한 환경적 처리를 거쳐 재활용하는 자원순환형 폐기물 관리체계로 정착되어 가는 추세이기 때문에 폐기물 및 산업부산물의 재활용이 크게 부상되고 있다. 대량으로 발생되는 폐기물의 하나인 폐석고는 지정폐기물로 분류되어 왔으나, 1994년 이후에는 일반폐기물로 분류되었으며, 처리비용 및 불순물 제거기술 부족 등으로 재활용이 극히 미비하였다. 그러나 최근들어 반건식 탈황공정 등을 이용한 불순물 제거기술이 개발되어 폐석고의 재활용에 관한 연구가 활발히 진행되고 있다. 본 연구에서는 폐석고를 콘크리트용 시멘트 대체재로의 활용 가능성을 규명하고 적정대체율을 도출하기 위하여 볼밀처리 전 후의 폐석고의 특성을 분석하였으며, 시멘트 사용량의 0, 5.0, 7.5, 10.0 및 12.5%를 폐석고로 대체한 콘크리트 시험체에 대한 강도 및 특성시험을 수행하였다.

All-ceramic restorations have had a more limited life expectancy than metal ceramic restorations because of their low strength. Their relatively lower strength and resistance to fracture have restricted the use of all-ceramic crowns to anterior applications where occlusal loads are lower. But there has been increasing interest in all-ceramic restorations because patients are primarily concerned with improved esthetics. Many efforts have been made to in prove the mechanical properties of dental ceramics. This study was designed to elucidate the influence of the luting agent on the strength of the Empress 2 crown (staining technique) cemented on human teeth. Seventy extracted human permanent molar teeth were chosen. Teeth were prepared for Empress 2 crowns with milling machine on a surveyor. A dental bur was placed in the mandrel that was positioned so that the long axis of the bur was perpendicular to the surveyor base. Dimensions of the Empress 2 crown preparation were $6^{\circ}$ taper on each side, $1.5{\pm}0.1mm$ shoulder margin, and 4mm crown height. The luting cements used in this study were as follow: 1. Uncemented 2. Zinc phosphate cements (Confi-Dental) 3. Conventional glass ionomer cement : Fuji 1 (GC) 4. Resin-modified glass ionomer cements : Fuji plus (GC) 5. Adhesive cements : Panavia F (Kuralay), Variolink II (Vivadent), Choice (Bisco). Fracture test using Instron. The crowns were loaded in compressive force to evaluate the effect of these cements on the breaking strength of these all-ceramic crowns. A steel ball with a diameter of 4mm was placed on the occlusal surface and load was applied to the steel ball by a cylindrical bolt with a crosshead speed of 0.5mm per minute until fracture occurred. The fractured surface was examined using Scanning Electron Microscopic Image (SEM) to discover the correlation between fracture strength and bonding capacity. Within the limitation of this in vitro study design, the results were as follows : 1. fomentations significantly increased the fracture resistance of Empress ceramic crowns compared to control. Uncemented (206.9 N): ZPC (812.9 N): Fuji 1 (879.5 N): Fuji Plus (937.7 N): Choice (1105.4 N): Variolink II (1221.1 N): Panavia F (1445.2 N). 2. Resin luting agent, treated by a silane bond enhancing agents, yielded a significant increase in fracture resistance. In some of the Panavia F group, a fracture extended into dentin. 3. According to SEM images of fractured Empress crowns, the stronger the bond at both interfaces(crown and die), the more fracture strength was acquired.

본 연구에서는 기지금속과의 고상이나 액상의 고용한이 거의 없는 금속-카본(carbon)계에서 고에너지 볼밀공정을 이용하여 고체 윤활 청동베어링용 Cu-C-X계 나노복합금속분말을 제조하고자 하였다. Cu-10wt.%C-5wt.%AI과 Cu-10wt.%C-5wt.%Fe의 혼합분말을 이르곤 분위기의 attritor내에서 기계적 합금화한 후 Cu-C-X의 나노복합금속분말의 미세조직 특성을 조사하였다. AI, Fe를 첨가하였을 때 10시간 이상의 MA공정에서부터 약 $10\mu\textrm{m}$이하의 미세한 Cu-C-X나노복합금속분말을 얻을 수 있었으며, MA 시간에 따른 분말의 형상과 미세구조 변화는 금속-금속계의 MA 과정과 유사하게 진행되는 것을 알 수 있었다. Cu-C-X 나노복합금속분말의 X-선 회절시험 결과, MA 시간에 따라 Cu와 C분말의 회절피크의 폭은 넓어지고 회절강도는 감소하였으며, 특히 흑연피크의 MA시간에 따른 소멸은 흑연의 낮은 원자산란계수 때문에 의한 X-선 흡수 영향으로 고찰하였다. Williamson-Hall식으로 계산된 Cu-C-X 나노복합금속분말내의 Cu의 결정립은 15시간 이상의 MA공정에서부터 약 10nm이하의 크기를 가졌으며, TEM 분석결과로는 불규칙한 형상의 약 10-30nm 크기로 복합화된 Cu결정립을 확인할 수 있었다.

An important business-field of world-wide steel-industry is the coating of thin metal-sheets with zinc, zinc-aluminum and aluminum based materials. These products mostly go into automotive industry. in particular for the car-body. into building and construction industry as well as household appliances. Due to mass-production, the processing is done in large continuously operating plants where the mostly cold-rolled metal-strip as the substrate is handled in coils up to 40 tons unwind before and rolled up again after passing the processing plant which includes cleaning, annealing, hot-dip galvanizing / aluminizing and chemical treatment. In the liquid Zn, Zn-AI, AI-Zn and AI-Si bathes a combined action of corrosion and wear under high temperature and high stress onto the transfer components (rolls) accounts for major economic losses. Most critical here are the bearing systems of these rolls operating in the liquid system. Rolls in liquid system can not be avoided as they are needed to transfer the steel-strip into and out of the crucible. Since several years, ceramic roller bearings are tested here [1.2], however, in particular due to uncontrollable Slag-impurities within the hot bath [3], slide bearings are still expected to be of a higher potential [4]. The today's state of the art is the application of slide bearings based on Stellite\ulcorneragainst Stellite which is in general a 50-60 wt% Co-matrix with incorporated Cr- and W-carbides and other composites. Indeed Stellite is used as the bearing-material as of it's chemical properties (does not go into solution), the physical properties in particular with poor lubricating properties are not satisfying at all. To increase the Sliding behavior in the bearing system, about 0.15-0.2 wt% of lead has been added into the hot-bath in the past. Due to environmental regulations. this had to be reduced dramatically_ This together with the heavily increasing production rates expressed by increased velocity of the substrate-steel-band up to 200 m/min and increased tractate power up to 10 tons in modern plants. leads to life times of the bearings of a few up to several days only. To improve this situation. the Mechanical Alloying (MA) TeChnique [5.6.7.8] is used to prOduce advanced Stellite-based bearing materials. A lubricating phase is introduced into Stellite-powder-material by MA, the composite-powder-particles are coated by High Energy Milling (HEM) in order to produce bearing-bushes of approximately 12 kg by Sintering, Liquid Phase Sintering (LPS) and Hot Isostatic Pressing (HIP). The chemical and physical behavior of samples as well as the bearing systems in the hot galvanizing / aluminizing plant are discussed. DependenCies like lubricant material and composite, LPS-binder and composite, particle shape and PM-route with respect to achievable density. (temperature--) shock-reSistibility and corrosive-wear behavior will be described. The materials are characterized by particle size analysis (laser diffraction), scanning electron microscopy and X-ray diffraction. corrosive-wear behavior is determined using a special cylinder-in-bush apparatus (CIBA) as well as field-test in real production condition. Part I of this work describes the initial testing phase where different sample materials are produced, characterized, consolidated and tested in the CIBA under a common AI-Zn-system. The results are discussed and the material-system for the large components to be produced for the field test in real production condition is decided. Outlook: Part II of this work will describe the field test in a hot-dip-galvanizing/aluminizing plant of the mechanically alloyed bearing bushes under aluminum-rich liquid metal. Alter testing, the bushes will be characterized and obtained results with respect to wear. expected lifetime, surface roughness and infiltration will be discussed. Part III of this project will describe a second initial testing phase where the won results of part 1+11 will be transferred to the AI-Si system. Part IV of this project will describe the field test in a hot-dip-aluminizing plant of the mechanically alloyed bearing bushes under aluminum liquid metal. After testing. the bushes will be characterized and obtained results with respect to wear. expected lifetime, surface roughness and infiltration will be discussed.

In analyzing the operational characteristics of a rice whitening machine, the internal radial pressure of the machine was measured using strain gage equipment. Changes in cylinder and feed screw configurations, screen type, cylinder speed and counter-pressure levels were examined to determine their impact on the quality and quantity of milled rice and the performance of the machine. The results are summarized as follows: 1. The internal radial pressure in the whitening chamber varied with the surface condition of the grain being processed. During the first or second pass through the machine, pressure was relatively low, reached a maximum after two to three passes with combinations I and II, three to six with combination III and then began to fall. 2. The pitch of the feed screw and the size of the feed gate opening which determine the rate of entry of grain into the whitening chamber, appeared to be the most important factor aff-::cting the degree of radial pressure, quality and quantity of milled rice and the efficiency of the machine. Using a feed screw with a wide pitch (4.8cm), radial pressure was relatively high and head rice recovery ratio \vere quite low. In this case capacity and machine effic?iency were much higher than obtained when using a feed screw with a narrow pitch (2.3cm). Very significant responses in radial pressure, head rice recovery rates and machine capacity were observed with changes in cylinder speed and counter-pressure levels when using the wide pitch feed screw. 3. The characteristics of the screen which surrounds the whitening chamber had an important effect on whitening efficiency. The existence of small protuberances on the original screen resulted in significant increases in both machine capacity and efficiency but without a significant decrease in head rice recovery or development of excessive radial pressure. Further work is required to determine the effects of screen surface conditions and the shape of the cylinderical steel roller on the rate of bran removal, machine efficiency and recovery rates. The size of the slotted perforations 0:1 the screen affects total milled rice recovery. The opening size on the original screen was fabricated to accommodate the round shape of Japonica rice varieties but was not suitable for the more slender Indica type. Milling Indica varieties with this screen resulted in a reduction in total milled rice recovery. 4. An increase in cylinder speed from 380 to 820 rpm produced a positive effect on head rice recovery for all machine combinations at every level of counter-pressure used in the tests. Head rice recovery was considerably lower at 380rpm using a wide screw pitch when compared to the results obtained at speeds from 600 to 820 r.p.m. The effects of cylinder speed On radial pressure, capacity and machine efficiency showed contrasting results, depending on the width of the feed screw pitch. With a narrow feed screw pitch (2.3cm), a direct proportional relationship was observed bet?ween cylinder speed and both radial pressure and machine efficiency. In contrast, using a 4.8 centimeter pitch feed roller produced a series of inverse relationships between the above variables. Based on the results of this study it is recommended when milling Indica type long grain rice varieties that the cylinder speed of the original machine be increased from 500-600 rmp up to a minimum of 800 rpm to obtain a greater abrasive effect between the grain and the screen. The pitch of the feed screw should be also reduced to decr?ease the level of internal radial pressure and to obtain higher machine efficiency and increased quality of milled rice with increased cylinder speeds. Further study on the interaction between cylinder speed and feed screw pitch is recommended. 5. An increase in the counter pressure level produced a negative effect On the head rice recovery with an increase in radial pressure, capacity, and machine efficiency over all combinations and at every level of cylinder speed. 6. Head rice recovery rates were conditioned primarily by the pressure inside the whitening chamber. According to the empirical cha racteristics curve developed in this study, the relationships of head rice recovery ($Y_h$) and machine capacity ($Y_c$/TEX>) to internal radial pressure ($X_p$) followed an inverse quadratic function and a linear function respectively: $$Y_h^\Delta=\frac{1}{{1.4383-0.2951X_p^\ast+0.1425X_p^{\ast\ast}}^2} , (R^2=0.98)$$$$Y_c^\Delta=-305.83+374.37X_p^{\ast\ast}, (R^2=0.88)$$The correlation between capacity and power consumption per unit of brown rice expressed in the following exponential function: $$Y_c^\Delta=1.63Y_c^{-0.7786^\{\ast\ast}, (R^2=0.94)$$These relationships indicate that when radial pressure increases above a certain range (1. 6 to 2.0 kg/$cm^2$ based On the results of the experiment) head ricerecovery decrea?ses in a quadratic relation with a inear increase in capacity but without any decrease in power consump tion per unit of brown rice. On the other hand, if radial pressure is below the range shown above, power consumption increases dramatically with a lin?ear decrease in capacity but without significant increases in head rice recovery. During the operation of a given whitening machine, the optimum radial pressure range or the correct capacity range should be selected by controlling the feed rate and/or counter-pressure keeping in mind the condition of the grain, particulary the hardness. It was observed that the total number of passes is related to radial pessure level, feed rate and counter-pressure level. The higher theradial pressure the fewer num?ber of pass required but with decreased head rice recovery. In particular, when using high feed rates, the total number of passes should be increased to more than three by reducing the counter-pressure level to avoid decreaseases in head rice recovery (less than 65 percent head rice recovery on the basis of brown rice) at every cylinder speed. 7. A rapid rise in grain temperature seemed to have a close relationship with the pressure generated inside the whitening chamber and, subsequently with head rice reco?very rates. The higher the rate of increase, the lower were the resulting head rice recoveries.

복합 레진은 소아치과 영역에서 대중적으로 사용되는 재료가 되었다. 하지만 복합 레진은 중합 수축을 최소화하기 위하여 적층 충전을 해야 하기 때문에 긴 시술 시간이 필요하다. 이러한 문제를 극복하기 위하여 임상가들은 bulk-filling 재료에 관심을 돌리기 시작하였고, 최근 bulk-base 복합 레진이 새로 출시되었다. 본 연구는 bulk-base 복합 레진의 깊이별 미세경도 측정값을 비교, 평가하였다. 실험군으로 1종의 저점도 bulk-base 복합 레진과 1종의 고점도 bulk-base 복합 레진을 사용하였고 대조군으로 1종의 전통적 복합 레진을 사용하였다. 각 깊이별 재료들의 미세경도에 대한 결과로 대조군의 경우는 중합 깊이가 깊어질수록 미세경도의 유의한 차이를 보였다(p < 0.05). 이에 반해 실험군 인 HFB는 0 mm와 4 mm에서, 그리고 MFB는 0 mm와 2 mm, 0 mm와 3 mm에서 각각 유의한 차이를 보였으나 높이에 따른 유의한 감소 경향을 보이지는 않았다. 각각의 깊이에서 시편들의 미세경도를 비교하였을 때 표면과 2 mm에서는 대조군이 실험군보다 큰 미세경도를 보였다(p < 0.05). 3 mm에서는 저점도 실험군이 대조군보다 미세경도가 크게 나왔으나 통계적으로 유의한 차이는 아니었다. 하지만 4 mm에서는 모든 실험군이 대조군보다 통계적으로 유의하게 큰 미세경도 값을 보였다(p < 0.05). 이번 실험을 통하여 bulk-base 복합 레진이 4 mm에서 기존의 복합 레진보다 더 높은 미세경도를 보였고 표면과 2 mm에서는 더 낮은 미세경도를 보이는 것을 관찰하였다. 그러므로 bulk-base 레진의 기계적 성질의 향상을 통해 표면의 낮은 미세경도 특성이 극복된다면 소아 환자의 수복 치료 시 적용이 고려되어 질 만 할 것이다.

국내산 밀로 수원 261, 수원 265, 은파, 고분, 알찬, 올그루, 금강밀 및 표준밀 ASW(Australian Standard White Wheat)의 제면 적성에 대하여 평가하였다. 국내산 밀의 원맥과 밀가루의 회분함량은 표준밀 ASW보다 0.1-0.3%정도 높게 나와 제분시 회분의 조절이 더 요구되었다. 단백질 함량은 밀가루의 가공공정을 좌우하는 것으로 국내산 밀 품종 중 수원 261, 수원 265, 금강밀이 각각 10.32, 11.3, 9.57%로 제면용으로 적합하였다. Farinograph의 valorimeter value(v.v.)는 은파, 올그루, 금강밀이 각각 68, 67, 61 v.v.로 표준밀인 ASW의 70v.v.와 비슷한 값을 나타내어 중력분에 속함을 알 수 있었다. Extensograph의 형상계수가 적을수록 박력분인데, 본 결과에서는 국내산 밀의 형상계수가 표준밀 보다 낮게 나타났다. 전분의 호화특성을 측정하는 amylograph에서 최고점도가 500-800 BU가 제면용으로 적합한데 국내산 밀 중 은파밀, 올그루밀, 금강밀이 이에 속하였다. 국내산 밀과 표준밀의 건면, 습면의 조리특성은 무게증가, 부피증가, 탁도로 나타내었는데 단백질 함량이 낮아 수분 침투가 많았던 올그루밀의 무게 , 부피증가가 높았다. 탁도는 무게, 부피의 증가와 비례하는 경향을 보이지는 않았으나 수원 265밀과 은파밀을 제외한 국내산 밀 품종은 표준밀 ASW와 비슷한 값을 보였다. 국수의 기계적 조직감을 습면, 건면으로 제조한 후 조리 전, 후로 나누어 TPA test를 측정하였다. 습면의 경우 조리에 의해 탄력성과 응집성을 증가시키며 국내산 밀이 표준밀 ASW보다 높은 값을 보여주었다. 건면의 경우 탄력성, 응집성은 조리 전, 후 품질간 뚜렷한 경향을 보이지 않았고 검성, 씹힘성, 견고성의 경우 전반적으로 국내산 밀 품종이 표준밀보다 높은 값을 보였다 인장력의 경우 습면은 시료간 차이가 없었으나 건면의 경우 국내산 밀이 표준밀보다 높은 인장력을 보였고, 표준밀은 습면의 인장력과 비슷한 값을 보였으나, 국내산 밀의 경우는 습면과 비교시 2-3g force전도 인장력이 상승되었다. 국내산 밀 품종과 표준밀 ASW의 색도는 밀가루와 반죽은 큰 차이를 보이지 않았으나 표준밀이 적색도가 낮았고, 습면의 경우 밀가루보다 백색도와 적색도가 크게 감소하였다. 건면의 경우도 시료간 차이를 보이지 않았으나 표준밀 ASW가 국내산 밀보다 역시 적색도가 낮았으며 습면과 비교시 백색도는 비슷하였고 적색도와 황색도는 증가되었다. 관능검사 항목은 습면과 건면으로 나누어 측정하였으며 습면, 건면 모두에서 금강밀이 전체적인 기호도에서 우수한 것으로 나타나 금강밀이 제면용으로 적합함을 알 수 있었다.
