  • This study is focused on the influence of mixture and construction factor on bleeding amount of concrete According to the results, Amount of bleeding with mixture factor increases with increase of water contents and W/C. Amount of bleeding with construction factors is larger in the case of placing height of 1m than in the case of placing height of 0 and 0.5m. Amount of bleeding is larger at the temperature of 20℃ than at the temperature of 35℃ and 5℃, and increases in order of vibration compacting, standard lamping and non tamping. Therefore, to reduce bleeding, it is thought that it is profitable to reduce water content within the range that fluidity and workability don't go bad, to lower the placing height and not to do compacting too much.

  • The posterior nasal bleeding sometimes develope a life threatening situation because of its limited access and the profuse vascular network of the bleeding area. There are various methods of hemostasis including packing, cautery, and arterial ligation those vary in effectiveness. But sometimes patients cannot tolerate these methods or show rebleeding sign. So, if all of these methods are not successful, we should consider the further treatment. The selective angiographic embolization has various advantages such as rapidness, repetition, good visualization, and being performed under local anesthesia, therefore it can provide useful way in patients with massive, intractable posterior nasal bleeding. We report a case of angiographic embolization for intractable posterior nasal bleeding patient and review the effectiveness of the this treatment.

  • Purpose : The purpose of this study is to report the effect of oriental treatments for the abnormal uterine bleeding. Methods : We treated a 30-year-old female who had been suffering from abnormal uterine bleeding for one month by Herb medication(Yikweseungyangtang, Chokyungjongoktang, Jahagehwan), acupuncture therapy and moxibustion therapy at the same time. And these teatments were based on 塞流([sailiu]-stanch blood), 澄源([chengyuan]-correct origin), 復舊([fuliu-restore) which are principles of treatment of 崩漏([benglou]-metrorrhagia). Results : After oriental medical teatment, abnormal uterine bleeding was disappeared and recovered the normal menstrual cycle. Conclusion : This case study shows that the oriental medical treatment in accordance with three principles of oriental treatment has an useful effect on abnormal uterine bleeding patient's treatment and recovery.

  • This paper investigates the influence of fine aggregates on bleeding of concrete. According to test results, as water content decreases, crushed sand content increases, fluidity shows decline tendency. As for aggregates kinds, concrete using sea sand shows most fluidity loss among the tested results. Compressive strength gains highly when crushed sand is used. As for bleeding of concrete, bleeding shows decline tendency because of increasing in powder content and filling effect of voids. Bleeding amount is in a decreasing order of magnitude for concretes made with the following aggregates: sea sand, river sand, and crushed sand. Accordingly, crushed sand mixed with river sand and sea sand with certain proportion enable to reduce bleeding and enhance strength.

  • This study is intended to investigate the influence of chemical admixture on bleeding of concrete. According to the results, the amount of bleeding with elapse of time does not make much difference in the case of naphthalene type water reducing agent(RN), Naphthalene type high performance water reducing agent(HN) and Melamine type high performance water reducing agent(HM), but it is largest in the case of Polycarbonic acid type high performance water reducing agent(HP). Bleeding speed also is highest in the case of HP in comparison with other chemical admixture. This prove that high performance water reducing agent like HP has little effect on fluidity of concrete, but influences the amount of bleeding more greatly, instead. As properties of hardened concrete, compressive strength makes no difference in the case of RN, HN and HM, but on the other hand, it increases in the case of HP due to a decrease of air content and the large amount of bleeding.

  • The purpose of this study is to present the two treatment case of patient with dysfunctional uterine bleeding. Each patient has received the Korean Medicinal treatment including acupuncture, moxibustion, and herbal medication twice a week for a month or six months. This efficacy of treatment was evaluated with the degree of bleeding by the number of pad used per day. After finishing treatment, two patients had stopped bleeding, and their menstrual cycle returned to the normal range. Moreover, additional clinical manifestations including leukorrhea, hot flush, bloating, feeling tired and irritability which refers to the premenstrual syndrome were also alleviated. This case report showed that the acupuncture, moxibustion, and the herbal medicinal treatment can be effective for the treatment of the dysfunctional uterine bleeding.

  • Adverse events such as hemoptysis and gastrointestinal hemorrhage during tyrosine kinase inhibitor treatment are relatively rare, but the severity of the bleeding can be higher than other common adverse events. It is necessary to educate patients about its possibility so that they can be found early. In this case report of radioiodine refractory thyroid cancer patient, hemoptysis and gastrointestinal bleeding has occurred following lenvatinib administration. Drug interruption and dose modification and dose interruption were required in addition to management for bleeding itself. It is necessary to confirm the high risk of bleeding before the administration of tyrosine kinase inhibitors, and to appropriately control the follow-up interval and drug dosage accordingly.

  • The common local causes of active gingival bleeding are the vessel engorgement and erosion by severe inflammation and injury to hypervascularity lesion. Abnormal gingival bleeding is also associated with systemic bleeding disorders (liver disease, leukemia etc.). There are many conventional methods for gingival bleeding control, such as, direct pressure, packing, electrocoagulation, tight suture and application of hemostatic agents. If the continuous gingival bleeding is not stopped in spite of the all local application methods, the medical consultation should be obtained for systemic condition care and the major feeding arterial embolization. This is a case report of severe gingival bleeding and periodontitis control in a patient with liver cirrhosis and oral metastatic lesion of hepatocellular carcinoma. The bleeding lesion was placed in left buccal mucosa and gingiva of the left mandibular molars. The control methods were dental crown removal, primary endodontic drainage, gingival sulcus drainage and maxillary arterial embolization with medical consultation.

  • 블리딩은 재료분리의 일종으로 콘크리트 구조물의 품질을 향상시키기 위해서는 손쉬운 블리딩 저감방안이 요구되고 있다. 그러나, 지금까지 알려진 블리딩 저감대책으로는 재료의 고품질화 및 배합비를 조정하는 등의 방법 외에는 손쉬운 해결책이 없는 실정이었다. 그러므로, 본 연구에서는 콘크리트의 블리딩을 효과적으로 저감할 수 있는 증점제 Type 블리딩저감제의 개발과 그 실용성을 검토한 것으로, 실험결과는 다음과 같다. 즉, 블리딩저감제의 개발은 MC 증점제 : 소포제 : 유동화제를 1 : 0.004 : 0.2의 비율로 혼합하면 가능한 것으로 밝혀졌고. 또한, 개발된 블리딩저감제는 혼입률 증가에 따라 굳지 않은 콘크리트의 유동성, 공기량 및 경화 콘크리트의 압축강도, 내동해성 등 제반 품질은 변동 없고, 블리딩의 저감효과는 우수한 것으로 나타나, 실무에서 콘크리트용 블리딩저감제로 유효하게 활용할 수 있음이 밝혀졌다.

  • Objectives: Heavy menstrual bleeding has a significant effect on women's daily life and health consequences for theirs. Attention to women's and girls' menstrual health is critical for their health. This study presents the results of a novel research on the effect of chamomile capsule on the amount of bleeding, and the duration and interval of menstrual cycles. Methods: The current study was a randomized, double-blind, clinical trial, which was carried out on 118 female students living in dorms of Guilan University of Medical Sciences. The participants were divided into two groups of 59, each receiving either chamomile capsule 250 mg or placebo three times a day, for an interval beginning from 7 days before the starting menstruation till the next onset. Higham chart is the pictorial blood loss assessment to determine the amount and duration of menstrual bleeding. Data were analyzed using SPSS version 20. Alpha was set at 0.05 for all analyses. Results: The average amount of bleeding in the chamomile group decreased after taking the capsule (p = 0.001). However, statistical tests did not show any significant difference in terms of duration and interval between two bleeding in both the experimental and control groups (p > 0.05). Conclusion: The present study showed that the chamomile capsule decreases the amount of menstrual bleeding and can be used as a therapeutic method. Conclusion:The present study showed that the chamomile capsule decreases the amount of menstrual bleeding and can be used as a therapeutic method.
