Malignant peritoneal mesothelioma is a rare neoplasm that arises from the mesothelium of a serosal cavity and is a rapidly fatal disease with a median survival of 4 to 12 months for untreated cases. Recently, we experienced a case with malignant peritoneal mesothelioma who was suspected hepatocelluar carcioma by abdominal CT scan and was confirmed by biopsy including immunohistochemical stain(calretinin) after surgery. We performed tumor excisions and wedge resection of the liver(segment Ⅷ)and inserted Tencoff catheter in abdominal cavity at 25th day of post-operation. We treated with intraperitoneal paclitaxel(25mg/m^(2)/day for 5 days) six courses monthly. She was well tolerable and is still living without any evidence of recurrence for 14th month of post-operation.

After the turmoil of Postmodern feast, A new tendency characterized as simplicity has been emerged in architecture. It seems clear that such a tendency, so called Minimal Architecture, has risen as a reaction to the surfeit of sign and the mixture of languages generated by Postmodernism. This new simplicity is also related to the tradition of Modem Architeture and the Minimal Art Movement in 1960's. This study aims to identify the concepts and philosophies of contemporary Minimal Architeture through analyzing the works and statements of the architects who tend to design in a way mentioned above. They are Wiel Arets (Netherland), Baumschlager & Eberle (Austria), Herzog & de Meuron (Swiss) and Dominique Perrault (France). The conclusions generated by the analysis are as follows; - They adopted simple primary volume to avoid the malinfluence on the already chaotic urban environment. In addition, the achieved strong monumentality in this way. - They are interested in making simple structure and repeating modular elements to achieve the economy and efficiency of construction. - Transparent and honest expression is preferred instead of attaching another ornamental skin on the skeleton of architeture.

The acidic treatment of waterworks sludge released organic materials as well as inorganics such as Al, Fe and Mn. Through solubilization as mentioned above, the content of suspended solids reduced by 18% at final pH 3.5. It also increased thickening efficiency and dewaterability of sludge. However overdosing of H_2SO_4 made dewaterability deteriorated. It showed that the optimal condition of acidic treatment be as follows; 5.5㎖ dose of H_2SO_4(97%)/1 sludge, final pH 3.5 and 15minutes of reaction time. Under these conditions, reduction efficiencies of sludge through thickening and dewatering were 57% and 92.2% respectively and then 7.8% of raw sludge released as cake compared to 10.5% without acidic pre-treatment. Therefore, mass of dewatered cake decreased by 26% through acidic treatment. Water content of dewatered cake was reduced from 71% to 62% due to this treatment. The changes of sludge properties including particle size, zeta-potential and bound water by acidic treatment appear to be important keys in assesment of the improvement of sludge dewaterability.

This study is in comparison the theoretical calculated values by the critical channel slope method with the field measured data in a braided channel. A consequence by the dimensional analysis showed to 3 dimensionless variable quantities one of the 6 variables, tractive force, particle size, water and sediment density, gravity acceleration and dynamic viscosity, related to transport of sediment particles. As a study channel reach we chose a small part of MIHO river which is a well developed braided channel in tributary of the KUM river catchment area, and it divided into 25 sections to the channel reaches 4,680m. Theoretical critical channel slope appeared at the section No. 21 and the meandering channel from began to appear instead of braided form at near section No.23 downstream about 320m from section No.21. And also the critical channel slope was 1/1,591 in theory but in field it is 1/1,613.

Representation has been main topic in teaching and learning mathematics for a long time. Moreover, teachers' deficiency of representation about fraction results in teaching algorithms without conceptual understanding. So, this paper was conducted to investigate and analysize the elementary preservice mathematics teachers' representation about fraction. 38 elementary preservice mathematics teachers participated in this study. This study results showed that, the only model of a fraction that was familiar to the preservice teachers was the part of whole one. And research showed that, they solved the problems about fraction well using algorithms but seldom express the sentence which illustrates the meaning of the operation by a fraction. Specially, the division aspect of a fraction was not familiar nor readily accepted. It menas that preservice teachers are used to using algorithms without a conceptual understanding of the meaning of the operation by a fraction. This results give us some implications. Most of all, teaching programs in preservice mathematics teachers education have to devise to form a network among the concepts in relation to fraction. And we must emphasize how to teach and what to teach in preservice mathematics teachers education course. Finally, we have to invent the various materials which can be used to educate both preservice teachers and elementary school students. If we want to improve the mathematical ability of students, we will concentrate preservice teachers education.

This study was performed to examine the effect of electro-chemical treatment on the precipitation of apatite-like calcium phosphate in simulated body fluid. Titanium plates were polished from #600 to #2,000 sand paper and one surface of each specimen was received an additional polishing sequence through 0.1㎛ alumina paste. To improve the activity of titanium plates, they were electro-chemically treated at 100㎃ for 20min in an electrolyte containing the calcium and phosphate ions, and the temperature of electrolyte was held constantly in the range of 20∼80℃ during the treatment. All specimens were soaked in the (Hanks solution) with pH 7.4 at 36.5℃ for 30 days, and the surfaces were examined with XRD, SEM, XPS. Precipitation of calcium phosphate and CaO were observed on the electro-chemically treated titanium surface in a simulated body fluid after treatment at 600℃. Precipitation of calcium phosphate was densified and coarsened with increasing the temperature of the electrolyte solution in the range of 20∼80℃. The calcium phosphate contained phosphate in the form of PO₄^(3-), HPO₄^(2-) and H₂PO₄^(-1).
