The incidence of pulmonary mycotic infection is increasing these days, and it can be frequently over-diagnosed as very well differentiated squamous cell carcinoma on sputum cytology due to its simi1ar morphology. Althouh each cell in pulmonary mycosis shows marked atypism or metaplastic changes, but we must considered the whole spectrums for differential diagnosis , ie. true tumor diathesis, volume of atypical cells, or chromatin pattern of the cell etc. Herein we report a case of pulmonary mycosis overdiagnosed as highly suspicious squamous cell carcinoma on sputum cytology.

Using of computers in design is a trend in recent years. A good suspension model is depend on the carefully prepared data like joint connection points or spring stiffness, etc.<br/> Once a good computer model is obtained, a parametric study for specific suspension design factor, like a toe angle, can be done to obtain sensitivity information. Using this information, several important design parameters for a specific design factor can be identified. Once a design of experiments is done using computer models, the results can be used to approximate a function which can best represent the experimentation. An optimum solution of this function can be used to fined an optimum design of a suspension system for a specific suspension design factor. Same method is again applied to other design factors iteratively until a good suspension system design is obtained.<br/>

Ride harshness is the important characteristic for a passenger bus. Since ride generally involves frequencies up to 30 Hz, special modelling technique should be used for ride harshness analysis. This paper investigates modelling technique of a passenger bus for ride analysis which involves coupling of rigid bodies and flexible bodies in one model. First step is to build a rigid model and next step is to establish FEM model of a bus body and leaf springs. Then, prepared FEM model is coupled with the rigid model Computational results of the coupled bus model is compared with the testing results. Then, sensitivity analysis was carried out to suggest the direction for the ride quality improvement.<br/> <br/>
