This research investigates the turbidity and flow of river for an year, 2005, in order to examine the relation of the generation of turbidity according to the outflow of min water. For this research, the region of Jawoon river where is the area of high land vegetable growing in the upper Soyang Reservoir is selected to observe actual floating materials that generate negative nutrition and turbidity of the Reservoir water and the changes of water quality by raining of each month, In addition, the researcher has conducted statistical inspection methods, such as correlation analysis and regression analysis on strength of raining force, and rain continuance time among the elements affecting the outflow of floating materials.

Recently, parallel kinematic machine tool with high accuracy and stiffness is causing great concern in 5-Axis processing which is applied in manufacturing with complicated shape products. However, there are some inherent difficulties in parallel kinematic machine tool such as a collision between workpiece and tool, over-cut and under-cut, verification of tool path route in progress. To solve these problem in advance, it needs machine simulation of parallel kinematic machine tool above all things. the purpose of this study is, therefore, carried out machine simulation for parallel kinematic machine tool and accumulation of technical knowledge for the productivity and efficiency in parallel kinematic machine tool through verification of 5-Axis machining.

A Study on failure strength of rock under uniaxial and triaxial compression tests was carried out for underground structural design in domestic and foreign countries recently. An experimental study was made for the core specimens of SANG-DONG tungsten mine. The results are as follows; 1. Failure strength was increasing gradually with increase of confining pressure. 2. Longitudinal and lateral strain increased in proportion to confining pressure under triaxial compression tests. 3. Stress-strain curves showed straight line to 62% of failure strength. 4. Effect of failure strength about porosity was 3.0% on the average and it represented lower value comparatively. 5. The values of triaxial compressive strength were distributed between 345 and 3082㎏/㎠, the mean value of which was 1063㎏/㎠. 6. The mean value of modulus of longitudinal elasticity(E) was 3.6X 10^5㎏/㎠ and poisson's ratio was 0.35.

Renal artery thrombosis may result from external trauma of a blunt nature. Such injury is induced by rapid deceleration resulting in the stretching of the renal vasculature, disruption of the arterial intima-the least elastic layer of the arterial wall and eventual thrombosis. The treatment of renal artery thrombosis is controversial, with physician's options divided between prompt surgical exploration with vascular repair and clinical observation. We experienced 1 case of traumatic renal artery thrombosis and report that with a brief review of the literature.

Recently, Hotels re faced with competitions form other highly upgraded calering business and the increased lobor costs. As one of the methods to solve these difficalties. Stratgic supply could be considered for a hotel business. Actually, SCM(Supply Chain Management) is a theory of a general administion. In recent, a lots of companies over the world have implemented SCM in their supply management and have been succed. Thus, this study is to consider about the possibility if SCM could be used in the hotel business. The survey is enhanced with the staffs who is charge of the purchasing of 60 hotels and analyzed by SPSS 10.0 and AMOS 4.0. This study is only concerned to material supply. But, in the hotel work, it could be also important for service supplies such as order information processing.

Overbreak, underbreak and range of disturbed rock zone (DRZ) are the most important factors in evaluating the results of tunnel blasting. These factors, which depend on the discontinuities in rock mass, the blasting patterns and drilling conditions, have been studied. The range of DRZ can be estimated by relationships between vibration velocity and associated tensile stress. A new computerized rocket jumbo drill has been adopted to reduce overbreak based on the analysis of drilling accuracy. In-situ blasting tests were also performed by varying initiating systems. Overbreak can be reduce from 34.5cm to 20cm. The range of DRZ is 0.2m with stoping holes and 0.4m with wall holes respectively. In addition, some methods to reduce DRZ have been presented in this study.

The pressure-time profile of the explosion gases can controlled for the use of cartridge explosive with two techniques known as Decoupling and spacing of the charges. Decoupling consists of a space between the explosive column and wall of the blast hole. Four different decoupling index 1.4, 1.8, 2.34, 3.0 are selected in this field study. The level of ground vibrations with each decoupling index was measured and the empirical particle velocity equation from these data was obtained. The condition of new cracks at blast hole are also examined. As the decoupling index is increased, the level of the blast vibration is decreased. But the cracks in rock masses are efficiently formed to remove the broken rock. The vibration constant associated with test sites is given as K=1564.5(D.I)^-1.3233 in terms of D.I.(decoupling index)

Bortezomib is the first clinically available proteasome inhibitor that is clinically effective in the treatment of multiple myeloma. A proteasome inhibitor acts through multiple mechanisms to arrest tumor growth, tumor spread, and angiogenesis. The main adverse effects of bortezomib are gastrointestinal symptoms, cytopenia, fatigue, and peripheral neuropathy. To date, severe paralytic ileus has not been reported as a toxic effect of bortezomib treatment in multiple myeloma. Bortezomib is a novel agent that has only been used clinically for 30 months, so a need exists to further evaluate its toxicity. We report a case of grade Ⅲ (NCI CTCAE v3.0) or grade Ⅳ(SWOG toxicity criteria) paralytic ileus in a 65-year-old man with relapsed multiple myeloma who underwent one cycle of single-agent bortezomib treatment scheduled in a 21-day cycle (1.3 mg/㎥ as a single i.v. bolus on days 1, 4, 8, and 11).
