  • We report a rare case of an extremely large right ventricular myxoma involving the ventricular side of the tricuspid valve. The tumor was excised along with the entire posterior leaflet and part of the anterior leaflet. The tricuspid valve was repaired by sliding valvuloplasty combined with ring annuloplasty.

  • This study aims to suggest guidelines of open classroom in open elementary school. It consists of following three parts. The first part takes a theoretical review of open education and open classroom. And the second makes analysis of architectural characteristics of open classroom as case studies which are analyzed in terms of modul, function and ratio of open space, etc. The last part is user need analysis of the open space.

  • Wire ropes are widely used in cable car, suspension bridge and elevator, etc. and composed of single or multi-layer strands. It is difficult to find out the characteristics of a strand or wire rope because of complicated geometry and contact condition. In this study, the axial stiffness is evaluated using finite element method and reliable finite element analysis model is presented, taking into consideration the convergence on the length. The axial stiffness predictive equation of a strand is developed using analysis of variance, which can be applicable for characterizing the relationship between load and displacement when the strand configuration is determined.
