AIM: To investigate how many discrepancies occur in patients before and after endoscopic treatment of referred adenoma and the reason for these results. METHODS: We retrospectively reviewed data from 554 cases of 534 patients who were referred from primary care centres for adenoma treatment and treated for endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) at Chungnam National University Hospital, from July 2006 to June 2009. Reendoscopy was examined in 142 cases and biopsywas performed in 108 cases prior to treatment. Three endoscopists (1, 2 and 3) performed all EMRs or ESDs and three pathologists (1, 2 and 3) diagnosed most of the cases. Transfer notes, medical records and endoscopic pictures of these cases were retrospectively reviewed and analyzed. RESULTS: Adenocarcinoma was 72 (13.0%) cases in total 554 cases after endoscopic treatment of referred adenoma. When the grade of dysplasia was high (55.0%), biopsy number was more than three (22.7%), size was no smaller than 2.0 cm (23.2%), morphologic type was depressed (35.8%) or yamada type Ⅳ (100%), and color was red (30.9%) or mixed-or-undetermined (25.0%), it had much more malignancy rate than the others (P < 0.05). All 18 cases diagnosed as adenocarcinoma in the re-endoscopic forceps biopsy were performed by endoscopist 1. There were different malignancy rates according to the pathologist (P = 0.027). CONCLUSION: High grade dysplasia is the most important factor for predicting malignancy as a final pathologic diagnosis before treating the referred gastric adenoma. This discrepancy can occur mainly through inappropriately selecting a biopsy site where cancer cells do not exist, but it also depends on the pathologist to some extent.

The support plates including all of the inner hulls such as E grade steel, weld seams and SUS304L were considered to establish the optimal stud welding condition in LNG ship building. The stainless steel plate was especially applied to the bracket on the liquid dome. The polished and etched surfaces of the welded stud and support plate were examined if the bead was properly formed. With the micrographic examination, the fusion boundary of metal weld zone formed by stud welding was analyzed to optimize the welding parameters. And also the analysis of the unacceptable welding faults such as cold and hot weld were performed. The mechanical tests such as tensile tests and bending tests were carried out to reveal any abnormal variation in the relationship of process parameters and the strength.

Stacking plates of CFRP composite materials are increasingly used because of their unique characteristics. However, unlike other materials used in metallurgy they have a disadvantage of uneven quality and anisotropy when combined with other composites. Hence, specimens of CFRP stacking plates are manufactured by changing orientation angles throughout three quasiisotropic plies （0°/45°/90°/-45°）68, （03°/453°/903°/-453°）2s, and （06°/456°/906°/-456°）s and throughout three cross plies （0°/90°/0°/90°）68, （03 °/903 °/03°/903°）2s, and （06 °/906 °/06°/906°）8 In this study 3-point bending tests and transverse bending tests have been carried out in order to find out mechanical characteristics according to orientation angles by stacking in 6 different types along with the change of stacking composition method of a CFRP composite.

BACKGROUND Transcatheter arterial embolization(TAE)has been widely used as an effective and a safe treatment method and was often used as an alternative to the surgical management,but there are limited studies on the efficacy and the safety for patients undergoing their secondary postpartum hemorrhage(PPH).AIM To evaluate the usefulness of TAE for secondary PPH focusing on the angiographic *** We conducted a research from January 2008 to July 2022 on all 83 patients(mean:32 years,range:24-43 years)presented with secondary PPH and they were treated with TAE in two university *** medical records and angiography were retrospective reviewed in order to evaluate the patients’characteristics,delivery details,clinical status and peri-embolization management,angiography and embolization details,technical/clinical success and *** group with active bleeding sign and the group without it were also compared and *** On angiography,46(55.4%)patients showed active bleeding signs such as contrast extravasation(n=37)or pseudoaneurysm(n=8)or both(n=1),and 37(44.6%)patients showed non-active bleeding signs such as only spastic uterine artery(n=2)or hyperemia(n=35).In the active bleeding sign group there were more multiparous patients,low platelet count,prothrombin time prolongation,and high transfusion *** technical success rates were 97.8%(45/46)in active bleeding sign group and 91.9%(34/37)in non-active bleeding sign group,and the overall clinical success rates were 95.7%(44/46)and 97.3%(36/37).An uterine rupture with peritonitis and abscess formation occurred to one patient after the embolization,therefore hysterostomy and retained placenta removal were performed which was a major *** TAE is an effective and a safe treatment method for controlling secondary PPH regardless of angiographic findings.
