  • This study is intended to investigate the fundamental properties of concrete which AE water reducing agent for reduction of bleeding is used, and the properties of bleeding reduction. According to the results, when the adding ratio of AE water reducing agent for reduction of bleeding increases, a range of normal fluidity and aimed air content are satisfied, setting time is faster than that of normal AE water reducing agent. And bleeding amount decreases, bleeding speed is highest between 60 and 90 min, and sinking depth increases drastically in 60 min. When. AE water reducing agent for reduction of bleeding is added, compressive strength shows a slight variation by air content, but there is not a large influence by addition of AE water reducing agent for reduction of bleeding. Synthetically, it proves that AE water reducing agent for reduction of bleeding satisfies aimed air content in the range of normal slump and can reduce only bleeding without quality variation of compressive strength.

  • This study is intended to investigate the properties of bleeding reduction of concrete using AE water reducing agent for the type of bleeding reduction with the replacement admixture. According to the results, when the adding ratio of AE water reducing agent for the type of bleeding reduction increases, a range of normal fluidity and aimed air content are satisfied, setting time is faster than that of normal AE water reducing agent. And bleeding amount decreases, bleeding speed is highest between 60 and 90 min, and sinking depth increases drastically in 50 min. When AE oater reducing agent for the type of bleeding reduction is added, compressive strength shows a slight variation by air content, but there is not a large influence by addition of AE water reducing agent for the type of bleeding reduction. Synthetically, it proves that AE water reducing agent for the type of bleeding reduction satisfies aimed air content in the range of normal slump and can reduce only bleeding without quality variation of compressive strength.

  • This paper describes the properties analysis of concrete using bleeding reduction agent. According to the results, the fluidity and the air content of fresh concrete with increase of bleeding reduction agent show little difference in compare with plain concrete which does not use bleeding reduction agent. The efficiency of bleeding reduction agent is confirmed because in variation of W/C and slump, the increase of bleeding reduction agent dosage reduces bleeding remarkably. And the compressive strength of hardened concrete does not show any differences with increase the dosage of bleeding reduction agent. Bleeding reduction agent does not have bad effect on the quality of concrete such as fluidity, air content and the strength of hardened concrete and so on, the dosage of it can reduce bleeding effectively.

  • Objectives: This paper aim to report the effects of korean medical treatment including Yikwiseungyang-tang-gagambang on patients with abnormal uterine bleeding. Methods: From 2012 August to 2017 June, six outpatient with abnormal uterine bleeding came to the clinic. The patients took Yikwiseungyang-tang-gagambang and got acupuncture and warm needle therapy. We assessed the patients' bleeding period and bleeding amount. Results: All patients' abnormal uterine bleeding stopped after they took Yikwiseungyang-tang-gagambang in 2~40 days. One patient restart slight bleeding, the bleeding stopped after continual korean medical treatment. Conclusions: Korean medical treatment including Yikwiseungyang-tang-gagambang is effective on patients with abnormal uterine bleeding.

  • Gastrointestinal bleeding is a common cause of hospitalization. Jejunal diverticula is a rare disease and it is an unusual cause of obscure gastrointestinal bleeding. After exclusion of the more common bleeding sources, small bowel diverticula should be considered as a possible rare cause of gastrointestinal bleeding. Jejunal diverticular bleeding is difficult to diagnose and treat because the bleeding site cannot be identified by routine endoscopy and radiologic studies. An exploratory operation is sometimes needed to diagnose and treat obscure gastrointestinal bleeding. If the bleeding site is certain, then surgical resection of the bleeding part of the bowel is the procedure of choice. We report here on a case of jejunal diverticular bleeding that was diagnosed by and treated with surgical resection.

  • The general local cause of gingival bleeding is the vessel engorgement and erosion by odontogenic infection. Abnormal gingival bleeding is also associated with systemic causes. Bleeding disorders in which continuous gingival bleeding is encountered include the followings : vascular abnormalities, platelet disorders, hypoprothrombinemia and other coagulation defects. There are classic methods for gingival bleeding control, such as, direct pressure, electrocoagulation, suture, crushing and application of hemostatic agents. If the continuous gingival bleeding is not stopped in spite of the conventional methods, the life of patient is threatened owing to upper airway obstruction, syncope, vomiting and hypovolemic shock. Therefore, the rapid and correct hemostatic method is very important in the emergency condition. This is a case report of continuous gingival bleeding control by primary endodontic drainage & suture in a disabled patient with systemic bleeding disorders.

  • Contrast-enhanced ultrasonography (CEUS) has been applied to evaluate parenchymal organs in human and veterinary medicine. However, to our knowledge, there is no report on the identification of active bleeding and the bleeding site in veterinary clinical patients. Herein, we describe the use of CEUS in two cases of abdominal bleeding caused by ruptured lesions with malignant abdominal tumors. One dog had a splenic hemangiosarcoma, which had metastasized to the liver; the other dog had hepatic cell carcinomas in the left hepatic lobe, which were lobectomized, and another nodule was identified in the right hepatic lobe. Immediately after the rupture of these oncogenic lesions was suspected, CEUS was performed to identify the bleeding sites. The active bleeding sites were confirmed by hyperechoic pooling signs in the arterial phase, and extravasation could be observed within the defects showing hypoechoic perfusions in the delayed phase of the CEUS. Microbubbles were also observed in the ascites; thus, CEUS could detect the presence of hemorrhage and accurately identify the bleeding site. Collectively, the study findings suggest the usefulness of CEUS in emergent situations as it enables rapid and noninvasive evaluation of bleeding points in case of active bleeding in dogs.

  • This study is intended to look into the influence of environment and construction factor on bleeding of concrete. According to the results, as wind is light, relative humidity is high and temperature is low, the amount of bleeding increases greatly, and evaporation speed is influenced greatly by order of wind, temperature and humidity. As the properties of bleeding by construction factor, the amount of bleeding increases with an increase of placing thickness, but the bleeding ratio, the amount of bleeding per unit volume, increases with a decrease of the placing thickness. Bleeding speed is fastest at about 90 minute after placing concrete. Also, as wind is light, relative humidity is high, temperature is low and the placing thickness is thick, bleeding speed grow faster.

  • While oral and maxillofacial surgery such as orthognathic surgery, TMJ surgery is in progress, there always exists a risk of bleeding from maxillary artery, and this perplexes the surgeon in operation. In case of massive bleeding, it is mostly very difficult or even impossible to take an immediate action in order to stop bleeding. Even when hemostasis is possible by applying such methods as the use of local hemostatics, pressing, electrocoagulation or direct ligation, there is a high risk of secondary bleeding. Therefore, in case there is bleeding from maxillary artery, it is the best to restrain bleeding completely either by the ligation of the artery in bleeding in operation fields or by the ligation of the external carotid artery.
