Abstract: The present invention relates to a flexible joint coupler coupled with a corrugated flexible pipe to function as a connection pipe connecting a sprinkler head coupled to an elevation fixating bracket equipped to install the sprinkler head at an appropriate height with an interior ceiling surface and a fire fighting pipe supplying a fire extinguishing solution. In particular, in the past, directly coupling a flexible pipe to a sprinkler head was impossible due to very weak structural strength of the flexible pipe made of a thin sheet of material such that the flexible pipe and the sprinkler head were coupled by a coupler with a coupling nut. However, in the present invention, the flexible joint coupler of an integrated structure has a configuration simplified by pressurizing the flexible pipe and a small coupler with a small and lightweight crimp ring installed in the outside of the flexible pipe to couple the flexible pipe and the small coupler, and then coupling the elevation fixating bracket to the crimp ring. In addition, the flexible joint coupler is formed into a structure firm and airtight, and capable of remarkably reducing manufacturing cost while reducing the number of leaks.

Abstract: The present invention relates to a method of providing information for predicting lymph node metastasis of gastric cancer, and more particularly, to a method of providing information for predicting lymph node metastasis of gastric cancer by combining a maximum standard uptake coefficient of primary cancer (T_SUVmax) and a maximum standard uptake coefficient of lymph nodes (N_SUVmax) with hematological information of a gastric cancer patient in fluoro-2-deoxyglucose (F-18 FDG) positron emission tomography/computed tomography (PET/CT). In the present invention, it was found that the maximum standard uptake coefficient of primary cancer (T_SUVmax) and the maximum standard uptake coefficient of lymph nodes (N_SUVmax) obtained from F-18 FDG PET/CT before surgery and a tumor marker CA19-9 among hematological indicators and albumin are statistically significant related factors in predicting the lymph node metastasis in multivariate logistic regression analysis. Finally, it was found that an area under curve (AUC) of a model created with four parameters T_SUVmax, N_SUVmax, CA19-9, and albumin is 0.780, which is a most suitable model for predicting the lymph node metastasis of the gastric cancer. Accordingly, the above four parameters are used to effectively provide information on whether the gastric cancer has metastasized to the lymph nodes.
