Gastric cancer is histologically classified into two types. One is the intestinal and diffuse type according to Lauren's classification, and the other is the differentiated and undifferentiated type based on Nakamura's classification. In 2007, Japanese groups proposed a new type of well-differentiated gastric adenocarcinoma in the gastric fundic glands with distinct endoscopic and clinicopathologic features. This is gastric adenocarcinoma of the fundic-gland type (GA-FG), a rare variant of gastric cancer. In a 2012 Korean study, of 6,000 cases of gastric cancer tissues, only three cases of GA-FG were identified. GA-FG is usually located in the upper third of the stomach and not known to be associated with the Helicobacter pylori infection. We herein report a case of GA-FG diagnosed in a 63-year-old man. A gastric polyp was incidentally detected during an upper endoscopy screening while conducting a health check-up, and he was diagnosed with GA-FG after an endoscopic mucosal resection (EMR) was conducted for diagnostic and therapeutic purposes. Our case suggests that for both diagnostic and therapeutic purposes, EMR may be beneficial in case of gastric polyps with suspected GA-FG.

This paper examined for the dynamic elastic-plastic response behavior of framed structures composed of composite beams under the earthquake loading. The elastic-plastic incremental stiffness matrix of composite beams is derived based on the Newmark's differential equation and on the generalized hinge method. Next, using the elastic-plastic stiffness matrix, the composite effects on the dynamic elastic-plastic response behavior of multi-story multi-bay building frames are examined against earthquake excitation. The frames used in the analysis are designed according to the plastic design method.

This paper describes on the elastic stiffness and moment distribution of composite beam frames under horizontal loads by using elastic stiffness matrix of composite beam. In estimating moments distribution of Composite beam frames eiastic stiffness of composite beam is unimformed in Design Recommendation for Composite Constructions. So it is overestimated in negative bending area and underestimated in positive bending area. Then, this paper throw light on moment distribution behavior of composite beam frames under horizontal loads by using elastic stiffness matrix of composite beams. And on using D-Value Method, to consider equivalent rigid ratio as varying cross section members of composite beam show possibility of elastic stress distribution of composite beam frames so high approximate value.

Although the research for the behavior of steel member that is subjected to combined stress has done fully, the research for behavior of steel member that is subjected to stress under the single axial force is not done fully. The purpose of this study are to find the elastic-plastic torsion analytical method using the generaliged plastic hinge method for the H-shaped section member that is in restricted to the bending moment within the torsion analytical method using the existing experimental results.
